Forward-Looking Information This prospectus, including the information we incorporate by reference, includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. You can identify our forward-looking statements by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "plan," "forecast," "budget," "goal" or other words that convey the uncertainty of future events or outcomes. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements in this prospectus, any prospectus supplement and the documents we have incorporated by reference. The forward-looking statements are not guarantees of future performance, and we caution you not to rely unduly on them. We have based many of these forward-looking statements on expectations and assumptions about future events that may prove to be inaccurate. Our management considers these expectations and assumptions to be reasonable, but they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks, contingencies and uncertainties relate to, among other matters, the following: . our acquisition and national operating strategies; . our ability to integrate the businesses we acquire; . our ability to obtain the capital necessary to finance our growth strategies; . the availability of qualified personnel; . the trends we anticipate in our business; . the level of activity in the construction industry generally and in our local markets for ready-mixed concrete; . the highly competitive nature of our business; . changes in, or our ability to comply with, governmental regulations, including those relating to the environment; . our labor relations and those of our suppliers of cement and aggregates; and . our ability to control costs and maintain quality. We have discussed some of these factors in more detail in the "Risk Factors" section of this prospectus. These factors are not necessarily all the important factors that could affect us. We advise you that you should (1) be aware that important factors we do not refer to above could affect the accuracy of our forward-looking statements and (2) use caution and common sense when considering our forward-looking statements. We do not intend to update these statements unless the securities laws require us to do so. About U.S. Concrete, Inc. U.S. Concrete provides ready-mixed concrete and related products and services to the construction industry in several major markets in the United States. As of August 1, 2000, we have 63 operating plants producing approximately 4.9 million cubic yards of concrete annually. Our operations consist principally of formulating, preparing, delivering and placing ready- mixed concrete at the job sites of our customers. We provide services intended to reduce our customers' overall construction costs by lowering the installed, or "in-place," cost of concrete. These services include the formulation of new mixtures for specific design uses, on-site and lab-based product quality control and delivery programs we configure to meet our customers' needs. We completed our initial public offering in May 1999. At the same time, we acquired six ready-mixed concrete and related businesses and began operating 26 concrete plants in three major markets in the United States. Since our IPO and through August 1, 2000, we have acquired an additional 13 ready-mixed concrete and related businesses, operating an additional 37 concrete plants, in five additional major markets in the United States. 4

To increase our geographic diversification and expand the scope of our operations, we seek to acquire businesses operating under quality management teams in growing markets. Our acquisition strategy has two primary objectives. In a new market, we target one or more companies that can serve as platform businesses into which we can integrate other concrete operations. In markets where we have existing operations and seek to increase our market penetration, we pursue tuck-in acquisitions. In this prospectus, we refer to U.S. Concrete, Inc., its wholly owned subsidiaries and its ownership interest in equity affiliates as "we," "us" or "U.S. Concrete," unless we specifically state otherwise or the context indicates otherwise. Our principal executive offices are located at 1300 Post Oak Blvd., Suite 1200, Houston, Texas 77056, and our telephone number at that location is (713) 499-6200. 5

Risk Factors You should carefully consider the following matters, in addition to the other information we have provided in this prospectus, the accompanying prospectus supplement and the documents we incorporate by reference, before reaching a decision regarding an investment in our securities. The risks and uncertainties we describe below are not the only ones relating to these securities or facing our company. Additional risks and uncertainties not presently known to us or that we currently do not believe are material may also impact our business, operations, financial condition or results of operations. We have a limited history of operating and integrating acquired businesses, and we may not be able to realize our business strategy of reducing costs and achieving revenue enhancements in the operations of the businesses we acquire If we are unable to integrate or successfully manage the companies we have acquired or may acquire in the future, our business, financial condition and results of operations could be materially and adversely affected. We completed our initial public offering in May 1999. At the same time, we acquired six ready-mixed concrete and related businesses. Since our IPO and through August 1, 2000, we have grown rapidly through the acquisition of an additional 13 ready-mixed concrete and related businesses. To manage the combined enterprise on a profitable basis, we must implement several common systems and various control mechanisms in each of the businesses we acquire. We may not be able to realize our business strategy of reducing costs and achieving revenue enhancements in the operations of the businesses we acquire for a number of reasons, including the following: . we may fail to integrate the businesses we acquire into a cohesive, efficient enterprise with company-wide information and management systems and effective cost and other control mechanisms; . we will have to rely on existing accounting, information and administrative systems of acquired businesses, which may be inadequate, until we can implement our centralized systems; . our resources, including management resources, are limited and may be strained if we engage in a significant number of acquisitions, and acquisitions may divert our management's attention from initiating or carrying out programs to save costs or enhance revenues; and . our ability to realize significant cost savings and customer cross- selling opportunities in any market will depend on the extent to which our acquisition strategy succeeds in that market. We may be unsuccessful in identifying and acquiring sufficient acquisition candidates to carry out our growth strategy One of our principal growth strategies is to increase our revenues and the markets we serve through the acquisition of additional ready-mixed concrete and related businesses. We expect to face competition for acquisition candidates and we may not be able to identify and acquire sufficient suitable acquisition candidates available for sale at reasonable prices and on other reasonable terms for a number of reasons, including: . the unwillingness of candidates to sell during a period of growing demand for ready-mixed concrete; . competitors in our industry may outbid us; or . we may not have sufficient available capital to pay for acquisitions. 6

There are risks related to our operating and internal growth strategies A key element of our strategy is to increase the profitability and revenues of the businesses we acquire. Although we have been implementing this strategy by various means since our IPO, you have no assurance that we will be able to continue to do so successfully. Another key component of our strategy is to operate the businesses we acquire on a decentralized basis, with local management retaining responsibility for day-to-day operations, profitability and the internal growth of the individual business. If we do not implement and maintain proper overall business controls, this decentralized operating strategy could result in inconsistent operating and financial practices at the businesses we acquire, and our overall profitability could be adversely affected. Our ability to generate internal growth will be affected by, among other factors, our ability to: . emphasize new product development and value-added sales and marketing; . attract new customers; . hire and retain employees; and . reduce operating and overhead expenses. Many of the factors affecting our ability to generate internal growth may be beyond our control, and you have no assurance that our strategies will be successful or that we will be able to generate cash flow sufficient to fund our operations and to support internal growth. Our inability to achieve internal growth could materially and adversely affect our business, financial condition and results of operations. We may not have access to sufficient funding to finance future acquisitions If we cannot secure additional financing on acceptable terms, we may be unable to continue pursuing our acquisition strategy successfully and we may be unable to support our growth strategy. We cannot readily predict the timing, size and success of our acquisition efforts or the capital we will need for those efforts. We intend to continue to use our common stock as a significant component of the consideration we pay for future acquisitions. Issuances of common stock as acquisition consideration could have a dilutive effect on our then existing stockholders. If our common stock does not maintain a sufficient market value or potential acquisition candidates are unwilling to accept our common stock as part of the consideration for the sale of their businesses, we may be required to use more of our cash resources to pursue our acquisition program. Using cash for acquisition consideration limits our financial flexibility and increases the likelihood that we will need to seek additional capital through future debt or equity financings. If we seek more debt financing, we may have to agree to financial covenants that limit our operational and financial flexibility. Additional equity financing may dilute the ownership interests of our then existing stockholders. You have no assurance that additional debt or equity financing will be available on terms acceptable to us. Our principal credit facility contains a requirement to obtain the consent of the lenders for acquisitions exceeding a specified level of cash consideration. Our business growth could outpace the capability of our corporate management and systems We expect to grow both internally and through acquisitions. We expect to expend significant time and effort in evaluating, completing and integrating acquisitions and opening new facilities. We cannot be certain that our systems, procedures and controls will be adequate to support our operations as they expand. Any future growth also will impose significant additional responsibilities on members of our senior management and executive officers. Our success will also depend on recruiting new senior level managers and officers and we cannot be certain that we can recruit and retain such additional managers and officers. To the extent we are unable to manage our growth effectively, or are unable to attract and retain additional qualified management personnel, our business, financial condition and results of operations could be materially and adversely affected. 7

The departure of key personnel could disrupt our business We depend on the continued efforts of our executive officers and, in many cases, on senior management of the businesses we acquire. The loss of key personnel, or the inability to hire and retain qualified replacements, could adversely effect our business, financial condition and results of operations. We do not carry key-person life insurance on any of our employees. We may be unable to attract and retain qualified employees Our ability to provide high-quality products and services on a timely basis requires that we employ an adequate number of skilled plant managers, technicians and drivers. Accordingly, our ability to increase our productivity and profitability will be limited by our ability to employ, train and retain skilled personnel necessary to meet our requirements. Like many of our competitors, we are currently experiencing shortages of qualified personnel. You have no assurance that we will be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our growth strategy or that our labor expenses will not increase as a result of a shortage in the supply of skilled personnel. We may lose business to competitors who underbid us and otherwise be unable to compete favorably in our highly competitive industry We may lose business to competitors who underbid us and otherwise be unable to compete favorably in our highly competitive industry. Our competitive position in a given market will depend largely on the location and operating costs of our ready-mixed concrete plants and prevailing prices in that market. Price is the primary competitive factor among suppliers for small or simple jobs, principally in residential construction, while timeliness of delivery and consistency of quality and service as well as price are the principal competitive factors among suppliers for large or complex jobs. Our competitors range from small, owner-operated private companies offering simple mixes to subsidiaries or operating units of large, vertically integrated cement manufacturing and concrete products companies. Competitors having lower operating costs than we do or having the financial resources to enable them to accept lower margins than we do will have a competitive advantage over us for jobs that are particularly price-sensitive. Competitors having greater financial resources than we do to invest in new mixer trucks, build plants in new areas or pay for acquisitions also will have competitive advantages over us. Our operating results may vary significantly quarter-to-quarter The ready-mixed concrete business is subject to seasonal variations. In particular, demand for our products and services during the winter months is typically lower than in other months of the year due to inclement weather. Additionally, the ready-mixed concrete industry can be highly cyclical. As a result, our volume of business may be adversely affected by declines in construction in various geographic regions of the U.S. Our quarterly results may also be materially affected by: . the timing of acquisitions; . variations in the margins of jobs performed during any particular quarter; . the timing and magnitude of acquisition assimilation costs; . the budgetary spending patterns of customers; . costs we incur to support growth internally or through acquisitions or otherwise; . the change in mix of our customers and business; . increases in construction and design costs; and 8

. regional or general economic conditions. As a result, our operating results in any particular quarter may not be indicative of the results that you can expect for any other quarter or for the entire year. Our results of operations could be adversely affected as a result of goodwill amortization When we acquire a business, we record an asset called "goodwill" equal to the excess amount we pay for the business, including liabilities we assume, over the fair value of the tangible assets of the business we acquire. Under generally accepted accounting principles, we amortize this goodwill over its estimated useful life. We amortize goodwill over up to 40 years following the acquisition, which directly impacts our earnings in those years. Accounting regulatory bodies are considering reducing the maximum write-off period for goodwill for most companies to a period less than the amortization period we have currently scheduled for many of our acquisitions or otherwise modifying the treatment of goodwill in a manner that could increase the amount of the amortization charge for goodwill we might recognize in a given year. In addition, we periodically evaluate whether events or circumstances have occurred that indicate that the remaining useful life of goodwill may warrant revision or that the remaining balance may not be recoverable. Should we be required to accelerate the amortization of goodwill or write it off completely because of impairments or changes in generally accepted accounting principles, our results of operations may be materially and adversely affected. Governmental regulations, including environmental regulations, may result in increases in our operating costs and capital expenditures and decreases in our earnings A wide range of federal, state and local laws, ordinances and regulations apply to our operations, including the following matters: . land usage; . street and highway usage; . noise levels; and . health, safety and environmental matters. In many instances, we must have various certificates, permits or licenses in order to conduct our business. Our failure to maintain required certificates, permits or licenses or to comply with applicable governmental requirements could result in substantial fines or possible revocation of our authority to conduct some of our operations. Delays in obtaining approvals for the transfer or grant of certificates, permits or licenses, or failure to obtain new certificates, permits or licenses, could impede the implementation of our acquisition program. Governmental requirements that impact our operations include those relating to air quality, solid waste management and water quality. These requirements are complex and subject to frequent change. They impose strict liability in some cases without regard to negligence or fault and expose us to liability for the conduct of or conditions caused by others, or for our acts that complied with all applicable requirements when we performed them. Our compliance with amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of environmental conditions may require us to make material expenditures we currently do not anticipate. In addition, although we intend to conduct appropriate investigations with respect to environmental matters in connection with future acquisitions, we may fail to identify or obtain indemnification from all potential environmental liabilities of any acquired business. 9

Collective bargaining agreements, work stoppages and other labor relations matters may result in increases in our operating costs, disruptions in our business and decreases in our earnings At August 1, 2000, approximately 47% of our employees were covered by collective bargaining agreements. Any inability by us to negotiate acceptable new contracts with these unions could cause strikes or other work stoppages by the affected employees, and new contracts could result in increased operating costs attributable to both union and non-union employees. If any such strikes or other work stoppages were to occur, or if other of our employees were to become represented by a union, we could experience a significant disruption of our operations and higher ongoing labor costs which could materially adversely affect our business, financial condition and results of operations. In addition, the coexistence of union and non-union employees may lead to conflicts between union and non-union employees or impede our ability to integrate our operations efficiently. Labor relations matters affecting our suppliers of cement and aggregates could adversely impact our business from time to time. Our operations are subject to various hazards that may cause personal injury or property damage and increase our operating costs Operating mixer trucks, particularly when loaded, exposes our drivers and others to traffic hazards. Our drivers are subject to the usual hazards associated with providing services on construction sites, while our plant personnel are subject to the hazards associated with moving and storing large quantities of heavy raw materials. Our operating hazards can cause personal injury and loss of life, damage to or destruction of property, plant and equipment and environmental damage. Although we conduct training programs designed to reduce the risks of these occurrences, we cannot eliminate these risks. We maintain insurance coverage in amounts and against the risks we believe accord with industry practice, but this insurance may not be adequate to cover all losses or liabilities we may incur in our operations, and we may not be able to maintain insurance of the types or at levels we deem necessary or adequate or at rates we consider reasonable. We may incur material costs and losses as a result of claims our products do not meet regulatory requirements or contractual specifications Our operations generally involve providing mixed designs of concrete which must meet building code or other regulatory requirements and contractual specifications for durability, stress-level capacity, weight-bearing capacity and other characteristics. We generally warrant to our customers that the concrete we provide: (1) in its plastic state on site will be delivered on time and in conformity with applicable tests and contractual specifications; and (2) in its hardened state will satisfy any applicable industry compressive strength test conducted by an independent testing laboratory. If we fail to provide product in accordance with these requirements and specifications, claims may arise against us or our reputation may be damaged. The market price of our common stock may be volatile The market price of our common stock may be volatile. Factors that could cause that volatility include: . fluctuations in our annual or quarterly financial results or those of our competitors or consolidators having growth strategies similar to ours in other industries; . price and volume volatility in the stock market generally or in the group of companies having smaller market capitalizations similar to ours; . changes in the market valuations of other consolidators; . failures of our operating results to meet the estimates of securities analysts or the expectations of our stockholders or changes by securities analysts in their estimates of our future earnings; 10

. changing conditions in our cyclical industry or in the local and regional economies in which we operate; and . unfavorable publicity or changes in laws or regulations which adversely affect our industry or us. We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock Our certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such preferences, powers and relative, participating, optional and other rights, including preferences over our common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might afford holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the common stock. See "Description of Capital Stock -- Preferred Stock" and "-- Stockholders Rights Plan." Provisions in our corporate documents and Delaware law could delay or prevent a change in control of our company, even if that change would be beneficial to our stockholders The existence of some provisions in our corporate documents and Delaware law could delay or prevent a change in control of our company, even if that change would be beneficial to our stockholders. Our certificate of incorporation and bylaws contain provisions that may make acquiring control of our company difficult, including: . provisions relating to the classification, nomination and removal of our directors; . provisions limiting the right to call special meetings of our board of directors and our stockholders; . provisions regulating the ability of our stockholders to bring matters for action at annual meetings of our stockholders; . a prohibition of action by our stockholders without a meeting; and . the authorization given to our board of directors to issue and set the terms of preferred stock. In addition, we have adopted a stockholder rights plan that would cause extreme dilution to any person or group who attempts to acquire a significant interest in U.S. Concrete without advance approval of our board of directors, while the Delaware General Corporation Law would impose some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. See "Description of Capital Stock." 11

Use of Proceeds Unless we inform you otherwise in the prospectus supplement, we will use the net proceeds from the sale of the offered securities for general corporate purposes. These purposes may include acquisitions, working capital, capital expenditures, repayment and refinancing of indebtedness and repurchases and redemptions of securities. Pending any specific application, we may initially invest those funds in short-term marketable securities or apply them to the reduction of short-term indebtedness. Ratio of Earnings to Fixed Charges The following table presents our ratio of earnings to fixed charges for each of the periods shown. We have computed the ratios of earnings to fixed charges by dividing earnings by fixed charges. For this purpose, "earnings" consist of income before income taxes plus fixed charges exclusive of capitalized interest. "Fixed charges" consist of interest, whether expensed or capitalized, amortization of capitalized expenses relating to indebtedness and an estimate of the portion of annual rental expense on operating leases that represents the interest factor. Because our financial statements present Central Concrete Supply Co., Inc., one of the businesses we acquired in May 1999 when we completed our IPO, as the purchaser of the other businesses we have acquired and U.S. Concrete, in accordance with the purchase method of accounting, the following information reflects results of Central only for periods prior to June 1, 1999, the date we recorded our initial acquisitions for accounting purposes, and for U.S. Concrete and its consolidated subsidiaries after that date.

The debt securities will be either senior debt securities or subordinated debt securities. We will issue the debt securities under one or more separate indentures between us and a trustee that we will name in the prospectus supplement. Senior debt securities will be issued under a senior indenture, and subordinated debt securities will be issued under a subordinated indenture. We sometimes call the senior indenture and the subordinated indenture the "indentures." We have summarized selected provisions of the indentures and the debt securities below. This summary is not complete. You should read the indentures for provisions that may be important to you. We have filed the forms of the indentures with the SEC as exhibits to the registration statement. Please read "Where You Can Find More Information." In this summary description of the debt securities, all references to "U.S. Concrete" or "us" mean U.S. Concrete, Inc. only, unless we state otherwise or the context clearly indicates otherwise. General The senior debt securities will constitute senior debt and will rank equally with all our unsecured and unsubordinated debt. The subordinated debt securities will be subordinated to, and thus have a position junior to, any senior debt securities and all our other senior debt. The indentures will not limit the amount of debt we may issue under the indentures, and, unless we inform you otherwise in the prospectus supplement, they will not limit the 12

amount of other unsecured debt or securities we may incur or issue. We may issue debt securities under either indenture from time to time in one or more series, each in an amount we authorize prior to issuance. We conduct our operations through our subsidiaries, and they generate substantially all our operating income and cash flow. As a result, distributions or advances from our subsidiaries are important sources of funds to meet our debt service obligations. Contractual provisions or laws, as well as our subsidiaries' financial condition and operating requirements, may limit our ability to obtain from our subsidiaries cash that we need to pay our debt service obligations, including payments on the debt securities. In addition, holders of the debt securities will have a position junior to the claims of creditors of our subsidiaries on their assets and earnings. Unless we inform you otherwise in the prospectus supplement, the indentures and the debt securities will not contain: . any covenants or other provisions designed to protect holders of the debt securities in the event we participate in a highly leveraged transaction; or . provisions that give holders of the debt securities the right to require us to repurchase their securities in the event of a decline in our credit rating resulting from a takeover, recapitalization or similar restructuring or otherwise. The prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following: . the title of the debt securities; . the total principal amount of the debt securities; . whether the debt securities are senior debt securities or subordinated debt securities; . whether we will issue the debt securities in individual certificates to each holder or in the form of temporary or permanent global securities held by a depositary on behalf of holders; . the date or dates on which the principal of and any premium on the debt securities will be payable; . any interest rate, the date from which interest will accrue, interest payment dates and record dates for interest payments; . whether and under what circumstances any additional amounts with respect to the debt securities will be payable; . the place or places where payments on the debt securities will be payable; . any provisions for redemption or early repayment; . any sinking fund or other provisions that would obligate us to redeem, purchase or repay the debt securities prior to maturity; . the denominations in which we may issue the debt securities; . whether payments on the debt securities will be payable in foreign currency or currency units or another form, and whether payments will be payable by reference to any index or formula; 13

. the portion of the principal amount of the debt securities that will be payable if the maturity is accelerated, if other than the entire principal amount; . any additional means of defeasance of the debt securities, any additional conditions or limitations to defeasance of the debt securities or any changes in those conditions or limitations; . any changes in or additions to the events of default or covenants this prospectus describes; . any restrictions or other provisions relating to the transfer or exchange of the debt securities; . any terms for the conversion or exchange of the debt securities for other securities issued by U.S. Concrete or any other entity; and . any other terms of the debt securities. We may sell the debt securities at a discount, which may be substantial, below their stated principal amount. Those debt securities may bear no interest or interest at a rate that at the time of issuance is below market rates. If we sell any of the debt securities for any foreign currency or currency unit or if payments on the debt securities are payable in any foreign currency or currency unit, we will describe in the prospectus supplement the restrictions, elections, tax consequences, specific terms and other information relating to those debt securities and the foreign currency or currency unit. Subordination Under the subordinated indenture, payment of the principal, interest and any premium on the subordinated debt securities will generally be subordinated and junior in right of payment to the prior payment in full of all Senior Debt. Unless we inform you otherwise in the prospectus supplement, we may not make any payment of principal, interest or any premium on the subordinated debt securities if: . we fail to pay the principal, interest, premium or any other amounts on any Senior Debt when due; or . we default in performing any other covenant (a "covenant default") in any Senior Debt that we have designated if the covenant default allows the holders of that Senior Debt to accelerate the maturity of the Senior Debt they hold. Unless we inform you otherwise in the prospectus supplement, a covenant default will prevent us from making payments on the subordinated debt securities only for up to 179 days after holders of the Senior Debt give the trustee for the subordinated debt securities notice of the covenant default. The subordination provisions will not affect our obligation, which will be absolute and unconditional, to pay, when due, principal of, premium, if any, and interest on the subordinated debt securities. In addition, the subordination provisions will not prevent the occurrence of any default under the subordinated indenture. Unless we inform you otherwise in the prospectus supplement, the subordinated indenture will not limit the amount of Senior Debt that we may incur. As a result of the subordination of the subordinated debt securities, if we became insolvent, holders of subordinated debt securities may receive less on a proportionate basis than our other creditors. 14

Unless we inform you otherwise in the prospectus supplement, "Senior Debt" will mean all notes or other indebtedness, including guarantees, of U.S. Concrete for money borrowed and similar obligations, unless the indebtedness states that it is not senior to the subordinated debt securities or our other junior debt. Consolidation, Merger and Sale of Assets The indentures generally will permit a consolidation or merger between us and another entity. They also will permit the sale by us of our assets substantially as an entirety to a single entity. The indentures will provide, however, that we may consolidate with another entity to form a new entity or merge into any other entity or transfer or dispose of our assets substantially as an entirety to any other entity only if: . the resulting entity is organized and existing under the laws of any United States jurisdiction and assumes the due and punctual payments on the debt securities and the performance of our covenants and obligations under the applicable indenture and the debt securities; and . immediately after giving effect to the transaction, no default or event of default would occur and be continuing. Events of Default Unless we inform you otherwise in the prospectus supplement, the following will be events of default with respect to a series of debt securities: . our failure to pay interest or any required additional amounts on any debt securities of that series for 30 days; . our failure to pay principal of or any premium on any debt securities of that series when due; . our failure to deposit any mandatory sinking fund payment for that series of debt securities for 30 days; . our failure to comply with any of our covenants or agreements in the debt securities of that series or the applicable indenture, other than an agreement or covenant that we have included in that indenture solely for the benefit of other series of debt securities, for 90 days after written notice by the trustee or by the holders of at least 25% in principal amount of all the outstanding debt securities issued under that Indenture that are affected by that failure; . certain events involving bankruptcy, insolvency or reorganization of U.S. Concrete; and . any other event of default provided for that series of debt securities. A default under one series of debt securities will not necessarily be a default under another series. The trustee may withhold notice to the holders of the debt securities of any default or event of default, except in any payment on the debt securities, if the trustee in good faith determines that withholding notice is in the interest of the holders of the debt securities. If an event of default for any series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the series affected by the default (or, in some cases, 25% in principal amount of all senior debt securities or subordinated debt securities affected, voting as one 15

class) may declare the principal of and all accrued and all unpaid interest on those debt securities to be due and payable. If an event of default relating to events of bankruptcy, insolvency or reorganization occurs, the principal of and all accrued and unpaid interest on all the debt securities will become immediately due and payable without any action on the part of the applicable trustee or any holder. The holders of a majority in principal amount of the outstanding debt securities of the series affected by the default (or of all senior debt securities or subordinated debt securities affected, voting as one class) may in some cases rescind this accelerated payment requirement. Depending on the terms of our other indebtedness, an event of default under either of the indentures may give rise to cross defaults on our other indebtedness. A holder of a debt security of any series will be able to pursue any remedy under the applicable indenture only if: . the holder gives the trustee written notice of a continuing event of default for that series; . the holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the trustee to pursue the remedy; . the holder or holders offer to the trustee indemnity reasonably satisfactory to it; . the trustee fails to act for a period of 60 days after receipt of notice and offer of indemnity; and . during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request. This provision will not, however, affect the right of a holder of a debt security to sue for enforcement of any overdue payment. In most cases, holders of a majority in principal amount of the outstanding debt securities of a series (or of all debt securities affected, voting as one class) will be able to direct the time, method and place of: . conducting any proceeding for any remedy available to the applicable trustee; and . exercising any trust or power conferred on the applicable trustee not relating to or arising in respect of an event of default. Each indenture will require us to file with the trustee each year a written statement as to our compliance with the covenants that indenture contains. Modification and Waiver We may amend or supplement either indenture if the holders of a majority in principal amount of the outstanding debt securities of all series issued under the applicable indenture and affected by the amendment or supplement, acting as one class, consent to it. Without the consent of the holder of each debt security affected, however, no amendment or supplement may: . reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver; . reduce the rate of or change the time for payment of interest on any debt security; . reduce the principal of, premium on or any mandatory sinking fund payment for any debt security; 16

. change the stated maturity of any debt security; . reduce any premium payable on the redemption of any debt security or change the time at which any debt security may or must be redeemed; . change any obligation to pay additional amounts on any debt security; . make the payments on any debt security payable in any currency or currency unit other than as the debt security originally states; . impair the holder's right to institute suit for the enforcement of any payment on any debt security; . make any change in the percentage of principal amount of debt securities necessary to waive compliance with specified provisions of the applicable indenture or to make any change in the applicable indenture's provisions for modification; . waive a continuing default or event of default regarding any payment on any debt security; or . with respect to the subordinated indenture, modify the provisions relating to the subordination of any subordinated debt security in a manner adverse to the holder of that security. We and the applicable trustee may agree to amend or supplement either indenture or waive any provision of either indenture without the consent of any holders of debt securities in some circumstances, including: . to cure any ambiguity, omission, defect or inconsistency; . to provide for the assumption of our obligations under the indenture by a successor on any merger, consolidation or asset transfer; . to provide for uncertificated debt securities in addition to or in place of certificated debt securities or to provide for bearer debt securities; . to provide any security for or add guarantees of any series of debt securities; . to comply with any requirement to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939; . to add covenants that would benefit the holders of any debt securities or to surrender any rights we have under the indenture; . to add events of default with respect to any debt securities; . to make any change that does not adversely affect any outstanding debt securities of any series in any material respect; . to facilitate the defeasance or discharge of any series of debt securities if that change does not adversely affect the holders of debt securities of that series or any other series under the indenture in any material respect; and . to provide for the acceptance of a successor or another trustee. 17

The holders of a majority in principal amount of the outstanding debt securities of any series (or of all senior debt securities or subordinated debt securities affected, voting as one class) may waive any existing or past default or event of default with respect to those debt securities. Those holders may not, however, waive any default or event of default in any payment on any debt security or compliance with a provision that cannot be amended or supplemented without the consent of each holder affected. Defeasance When we use the term "defeasance," we mean discharge from some or all of our obligations under an indenture. If we deposit with the applicable trustee funds or government securities sufficient to make payments on the debt securities of a series on the dates those payments are due and payable, then, at our option, either of the following will occur: . we will be discharged from our obligations with respect to the debt securities of that series ("legal defeasance"); or . we will no longer have any obligation to comply with the restrictive covenants under the applicable indenture, and the related events of default will no longer apply to us, but some of our other obligations under the indenture and the debt securities of that series, including our obligation to make payments on those debt securities, will survive ("covenant defeasance"). If we defease a series of debt securities, the holders of the debt securities of the series affected will not be entitled to the benefits of the applicable indenture, except for our obligations to: . register the transfer or exchange of debt securities; . replace stolen, lost or mutilated debt securities; and . maintain paying agencies and hold moneys for payment in trust. Unless we inform you otherwise in the prospectus supplement, we will be required to deliver to the applicable trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the debt securities to recognize income, gain or loss for United States federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based on a ruling from the United States Internal Revenue Service or a change in law to that effect. Governing Law New York law will govern the indentures and the debt securities. Trustee If an event of default occurs and is continuing, the trustee must use the degree of care and skill of a prudent person in the conduct of his own affairs. The trustee will become obligated to exercise any of its powers under the indenture at the request of any of the holders of any debt securities only after those holders have offered the trustee indemnity reasonably satisfactory to it. Each indenture will limit the right of the trustee, if it is one of our creditors, to obtain payment of claims or to realize on certain property received for any such claim, as security or otherwise. The trustee may engage in other transactions with us. If it acquires any conflicting interest, however, it must eliminate that conflict or resign. 18

Form, Exchange, Registration and Transfer If we issue the debt securities in registered form, we will not charge a service charge for any registration of transfer or exchange of those securities. We may, however, require the payment of any tax or other governmental charge payable for that registration. Debt securities of any series will be exchangeable for other debt securities of the same series with the same total principal amount and the same terms but in different authorized denominations in accordance with the applicable indenture. Holders may present registered debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange when it is satisfied with the documents of title and identity of the person making the request. Unless we inform you otherwise in the prospectus supplement, we will appoint the trustee under each indenture as security registrar for the debt securities we issue in registered form under that indenture. If the prospectus supplement refers to any transfer agents initially designated by us, we may at any time rescind that designation or approve a change in the location through which any transfer agent acts. We will be required to maintain an office or agency for transfers and exchanges in each place of payment. We may at any time designate additional transfer agents for any series of debt securities or rescind the designation of any transfer agent. In the case of any redemption, neither the security registrar nor the transfer agent will be required to register the transfer or exchange of any debt security: . during a period beginning 15 business days before the day of mailing of the relevant notice of redemption and ending on the close of business on that day of mailing; or . if we have called the debt security for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part. Payment and Paying Agents Unless we inform you otherwise in the prospectus supplement, we will make payments on the debt securities in U.S. dollars at the office of the applicable trustee or any paying agent we designate. At our option, we may make payments by check mailed to the holder's registered address or, with respect to global debt securities, by wire transfer. Unless we inform you otherwise in the prospectus supplement, we will make interest payments to the person in whose name the debt security is registered at the close of business on the record date for the interest payment. Unless we inform you otherwise in the prospectus supplement, we will designate the trustee under each indenture as our paying agent for payments on debt securities we issue under that indenture. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts. Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will repay to us on our written request any funds they hold for payments on the debt securities that remain unclaimed for two years after the date upon which that payment has become due. After repayment to us, holders entitled to those funds must look only to us for payment. Book-entry Debt Securities We may issue the debt securities of a series in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. We may issue global debt 19

securities in either temporary or permanent form. We will describe in the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security. Description of Capital Stock Our authorized capital stock consists of: . 60,000,000 shares of common stock; and . 10,000,000 shares of preferred stock, issuable in series. Each authorized share has a par value of $.001. As of July 31, 2000, 21,981,827 shares of common stock were issued and outstanding. Also as of July 31, 2000, no shares of our preferred stock were issued and outstanding. In the discussion that follows, we have summarized selected provisions of our certificate of incorporation, as amended, and our amended and restated bylaws relating to our capital stock. This summary is not complete. You should read the provisions of our certificate of incorporation and bylaws as currently in effect for provisions that may be important to you. We have filed copies of those documents with the SEC, and they are incorporated by reference as exhibits to the registration statement. Please read "Where You Can Find More Information." Common Stock Each share of common stock has one vote in the election of each director and on other corporate matters, other than any matter that (1) solely relates to the terms of any outstanding series of preferred stock or the number of shares of that series and (2) does not affect the number of authorized shares of preferred stock or the powers, privileges and rights pertaining to the common stock. No share of common stock affords any cumulative voting rights. This means that the holders of a majority of the voting power of the shares voting for the election of directors can elect all directors to be elected if they choose to do so. Our board of directors may grant holders of preferred stock, in the resolutions creating the series of preferred stock, the right to vote on the election of directors or any questions affecting us. Holders of common stock will be entitled to dividends in such amounts and at such times as our board of directors in its discretion may declare out of funds legally available for the payment of dividends. We currently intend to retain our entire available discretionary cash flow to finance the growth, development and expansion of our business and do not anticipate paying any cash dividends on the common stock in the foreseeable future. Any future dividends will be at the discretion of our board of directors after taking into account various factors, including: . our financial condition and performance; . our cash needs and expansion plans; . our obligations to holders of any preferred stock we may issue; . income tax consequences; and . the restrictions Delaware and other applicable laws and our credit arrangements then impose. In addition, the terms of our principal credit facility prohibit the payment of cash dividends. 20

If we liquidate or dissolve our business, the holders of common stock will share ratably in all assets available for distribution to stockholders after our creditors are paid in full and the holders of all series of our outstanding preferred stock, if any, receive their liquidation preferences in full. The common stock has no preemptive rights and is not convertible or redeemable or entitled to the benefits of any sinking or repurchase fund. All issued and outstanding shares of common stock are fully paid and nonassessable. Any shares of common stock we offer and sell under this prospectus will also be fully paid and nonassessable. The common stock is quoted on the Nasdaq National Market under the symbol "RMIX." Preferred Stock At the direction of our board of directors, without any action by the holders of common stock, we may issue one or more series of preferred stock from time to time. Our board of directors can determine the number of shares of each series of preferred stock and the rights, preferences, privileges and restrictions, including dividend rights, voting rights, conversion or exchange rights, terms of redemption and liquidation preferences, of each series. The prospectus supplement relating to any series of preferred stock we offer will include specific terms relating to the offering. These terms will include some or all of the following: . the series designation of the preferred stock; . the maximum number of shares of the series; . the dividend rate (or the method of calculating the dividend), the date from which dividends will accrue and whether dividends will be cumulative; . any liquidation preference; . any optional redemption provisions; . any sinking fund or other provisions that would obligate us to redeem or repurchase the preferred stock; . any terms for the conversion or exchange of the preferred stock for any other securities; . any voting rights; and . any other preferences and relative, participating, optional or other special rights or any qualifications, limitations or restrictions on the rights of the shares. Any preferred stock we offer and sell under this prospectus will be fully paid and nonassessable. The description of the terms of the preferred stock to be set forth in an applicable prospectus supplement will not be complete and will be subject to and qualified by the certificate of designation relating to the applicable series of preferred stock. The registration statement will include the certificate of designation as an exhibit or will incorporate the certificate of designation by reference. You should read that document for provisions that may be important to you. Undesignated preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a tender offer, proxy contest, merger or otherwise, and to thereby 21

protect the continuity of our management. The issuance of shares of preferred stock may adversely affect the rights of the holders of common stock. For example, any preferred stock issued may rank prior to the common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. As a result, the issuance of shares of preferred stock may discourage bids for common stock or may otherwise adversely affect the market price of the common stock or any existing preferred stock. Stockholder Rights Plan On May 10, 1999, we entered into a rights agreement with American Stock Transfer & Trust Company, as rights agent, providing for the issuance of preferred stock purchase rights to holders of common stock. Under the plan, each share of common stock currently includes one right to purchase from us a unit consisting of one one-hundredth of a share of our Series A junior participating preferred stock at an exercise price of $35.00 per unit, subject to adjustment. We have summarized selected provisions of the rights agreement below. This summary is not complete. You should read the rights agreement for provisions that may be important to you. We have filed a copy of the rights agreement with the SEC, and it is incorporated by reference as an exhibit to the registration statement. Please read "Where You Can Find More Information." The rights are attached to all certificates representing our currently outstanding common stock and will attach to all common stock certificates we issue prior to the "rights distribution date." That date would occur, except in some cases, on the earlier of: . 10 days following a public announcement that a person or group of affiliated or associated persons (collectively, an "acquiring person") has acquired or obtained the right to acquire beneficial ownership of 15% or more of the outstanding shares of common stock; or . 10 business days following the start of a tender or exchange offer that would result, if closed, in a person's becoming an acquiring person. Our board of directors may defer the rights distribution date in some circumstances, and some inadvertent acquisitions will not result in a person becoming an acquiring person if the person promptly divests itself of sufficient common stock. Until the rights distribution date: . common stock certificates will evidence the rights; . the rights will be transferable only with those certificates; . those certificates will contain a notation incorporating the rights agreement by reference; and . the surrender for transfer of any of those certificates also will constitute the transfer of the rights associated with the stock that certificate represents. The rights are not exercisable until after the rights distribution date and will expire at the close of business on April 30, 2009, unless we earlier redeem or exchange them as we describe below. As soon as practicable after the rights distribution date, the rights agent will mail certificates representing the rights to holders of record of common stock as of the close of business on that date and, from and after that date, only separate rights certificates will represent the rights. 22

We will not issue rights with any shares of common stock we issue after the rights distribution date, except (1) as our board of directors otherwise may determine and (2) together with shares of common stock we issue as a result of previously established incentive plans or convertible securities. A "flip-in event" will occur under the rights agreement when a person becomes an acquiring person otherwise than as a result of a "permitted offer." The rights agreement defines "permitted offer" to mean a tender or exchange offer for all outstanding shares of common stock at a price and on terms that a majority of the independent members of our board of directors determines to be fair to and otherwise in our best interests and the best interests of our stockholders. If a flip-in event occurs, our board of directors may, at any time until 10 days after the public announcement that a person has become an acquiring person, cause us to redeem the rights in whole, but not in part, at a redemption price of $.01 per right, subject to adjustment for any stock split, stock dividend or similar transaction occurring before the date of redemption. At our option, we may pay that redemption price in cash, shares of common stock or any other consideration our board of directors selects. The rights will not be exercisable after a flip-in event until they are no longer redeemable. If our board of directors timely orders the redemption of the rights, the rights will terminate on the effectiveness of that action. If a flip-in event occurs and we do not redeem the rights, each right, other than any right that has become null and void as we describe below, will become exercisable, at the time we no longer may redeem it, to receive the number of shares of common stock (or, in some cases, cash, property or other of our securities) which has a "current market price" (as the rights agreement defines that term) equal to two times the exercise price of the right. When a flip-in event occurs, all rights that then are, or under the circumstances the rights agreement specifies previously were, beneficially owned by an acquiring person or specified related parties will become null and void in the circumstances the rights agreement specifies. A "flip-over event" will occur under the rights agreement when, at any time from and after the time a person becomes an acquiring person, (1) we are acquired in a merger or other business combination transaction, other than specified mergers that follow a permitted offer of the type we describe above, or (2) 50% or more of our assets or earning power is sold or transferred. If a flip-over event occurs, each holder of a right (except rights that previously have become void as we describe above) thereafter will have the right to receive, on exercise of that right, the number of shares of common stock of the acquiring company which has a current market price equal to two times the exercise price of the right. The number of outstanding rights associated with a share of common stock, the number of fractional shares of junior participating preferred stock issuable on exercise of a right and the exercise price of the rights are subject to adjustment in the event of a stock dividend on, or a subdivision, combination or reclassification of, the common stock occurring prior to the rights distribution date. The exercise price of the rights and the number of fractional shares of junior participating preferred stock or other securities or property issuable on exercise of the rights also are subject to adjustment from time to time to prevent dilution in the event of some transactions affecting the junior participating preferred stock. With some exceptions, the rights agreement will not require us to adjust the exercise price of the rights until cumulative adjustments amount to at least 1% of that exercise price. It also will not require us to issue fractional shares of junior participating preferred stock that are not integral multiples of one one-hundredth, and, in lieu thereof, we will make a cash adjustment based on the market price of the junior participating preferred stock on the last trading date prior to the date of exercise. The rights agreement reserves to us the right to require prior to the occurrence of any flip-in event or flip-over event that, on any exercise of rights, a number of rights must be exercised so that we will issue only whole shares of junior participating preferred stock. 23

At any time after the occurrence of a flip-in event and prior to a person's becoming the beneficial owner of 50% or more of the shares of common stock then outstanding or the occurrence of a flip-over event, we may, at our option, exchange the rights (other than rights owned by an acquiring person or an affiliate or an associate of an acquiring person, which will have become void), in whole or in part, at an exchange ratio of one share of common stock, and/or other equity securities we deem to have the same value as one share of common stock, per right, subject to adjustment. During the time we may redeem the rights, we may, at the direction of our board of directors, amend any of the provisions of the rights agreement other than the redemption price. Thereafter, we may amend the provisions of the rights agreement, other than the redemption price, only as follows: . to cure any ambiguity, defect or inconsistency; . to make changes that do not materially adversely affect the interests of holders of rights, excluding the interests of any acquiring person; or . to shorten or lengthen any time period under the rights agreement; provided, however, that we cannot lengthen the time period governing redemption if the rights are no longer redeemable. Until a right is exercised, the holder thereof, as such, will have no rights to vote or receive dividends or any other rights as a stockholder. The rights have anti-takeover effects. They will cause severe dilution to any person or group that attempts to acquire us without the approval of our board of directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire us, even if the acquisition may be favorable to the interests of our stockholders. Because our board of directors can redeem the rights or approve a permitted offer, the rights should not interfere with a merger or other business combination our board of directors approves. Limitation on Directors' Liability Delaware law authorizes Delaware corporations to limit or eliminate the personal liability of their directors to them and their stockholders for monetary damages for breach of a director's fiduciary duty of care. The duty of care requires that, when acting on behalf of the corporation, directors must exercise an informed business judgment based on all material information reasonably available to them. Absent the limitations Delaware law authorizes, directors of Delaware corporations are accountable to those corporations and their stockholders for monetary damages for conduct constituting gross negligence in the exercise of their duty of care. Delaware law enables Delaware corporations to limit available relief to equitable remedies such as injunction or rescission. Our certificate of incorporation limits the liability of our directors to us or our stockholders to the fullest extent Delaware law permits. Specifically, no member of our board of directors will be personally liable for monetary damages for any breach of the member's fiduciary duty as a director, except for liability: . for any breach of the member's duty of loyalty to us or our stockholders; . for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; . for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; and . for any transaction from which the member derived an improper personal benefit. 24

This provision could have the effect of reducing the likelihood of derivative litigation against our directors and may discourage or deter our stockholders or management from bringing a lawsuit against our directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefitted our stockholders and us. Our bylaws provide indemnification to our officers and directors and other specified persons with respect to their conduct in various capacities, and we have entered into agreements with each of our directors and executive officers which indemnify them to the fullest extent Delaware law and our certificate of incorporation permit. Statutory Business Combination Provision As a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. In general, Section 203 prevents an "interested stockholder," which is defined generally as a person owning 15% or more of a Delaware corporation's outstanding voting stock or any affiliate or associate of that person, from engaging in a broad range of "business combinations" with the corporation for three years following the date that person became an interested stockholder unless: . before that person became an interested stockholder, the board of directors of the corporation approved the transaction in which that person became an interested stockholder or approved the business combination; . on completion of the transaction that resulted in that person's becoming an interested stockholder, that person owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, other than stock held by (1) directors who are also officers of the corporation or (2) any employee stock plan that does not provide employees with the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or . following the transaction in which that person became an interested stockholder, both the board of directors of the corporation and the holders of at least two-thirds of the outstanding voting stock of the corporation not owned by that person approve the business combination. Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors, if a majority of the directors who were directors prior to any person's becoming an interested stockholder during the previous three years, or were recommended for election or elected to succeed those directors by a majority of those directors, approve or do not oppose that extraordinary transaction. Other Matters Some of the provisions of our certificate of incorporation and bylaws discussed below may have the effect, either alone or in combination with the provisions of Section 203 of the Delaware General Corporation Law, of making more difficult or discouraging a tender offer, proxy contest or other takeover attempt that our board of directors opposes but that a stockholder might consider to be in its best interest. Our certificate of incorporation provides that our stockholders may act only at an annual or special meeting of stockholders and may not act by written consent. Our bylaws provide that only the chairman of our board of directors or a majority of the board may call a special meeting of our board of directors or of our stockholders. Our certificate of incorporation provides for a classified board of directors. Except for directors that the holders of preferred stock may elect, our board of directors is divided into three classes, with the directors of each 25

class as nearly equal in number as possible. At each annual meeting of our stockholders, the term of a different class of our directors will expire. As a result, we contemplate that stockholders will elect approximately one-third of our board of directors each year. Board classification could prevent a party who acquires control of a majority of our outstanding voting stock from obtaining control of our board of directors until the second annual stockholders' meeting following the date that party obtains that control. Our certificate of incorporation provides that the number of directors will be as the board of directors determines from time to time, but will not be less than three. It also provides that directors may be removed only for cause and then only by the affirmative vote of the holders of at least a majority of all outstanding voting stock entitled to vote. This provision, along with the provisions authorizing the board of directors to fill vacant directorships, will prevent stockholders from removing incumbent directors without cause and filling the resulting vacancies with their own nominees. Stockholder Proposals Our bylaws contain advance-notice and other procedural requirements that apply to stockholder nominations of persons for election to the board of directors at any annual or special meeting of stockholders and to stockholder proposals that stockholders take any other action at any annual meeting. In the case of any annual meeting, a stockholder proposing to nominate a person for election to the board of directors or proposing that any other action be taken must give our corporate secretary written notice of the proposal not less than 90 days and not more than 120 days before the anniversary date of the immediately preceding annual meeting. These stockholder proposal deadlines are subject to exceptions if the pending annual meeting date differs by more than specified periods from that anniversary date. If the chairman of our board of directors or a majority of the board of directors calls a special meeting of stockholders for the election of directors, a stockholder proposing to nominate a person for that election must give our corporate secretary written notice of the proposal not earlier than 120 days prior to that special meeting and not later than the last to occur of (1) 90 days prior to that special meeting or (2) the 10th day following the day we publicly disclose the date of the special meeting. Our bylaws prescribe the specific information any advance written stockholder notice must contain. The advance-notice procedure may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if the proper procedures are not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal, without regard to whether consideration of those nominees or proposals might be harmful or beneficial to our company and our stockholders. Transfer Agent and Registrar The transfer agent and registrar for the common stock is American Stock Transfer & Trust Company. Description of Warrants We may issue warrants to purchase debt securities, common stock, preferred stock or other securities. We may issue warrants independently or together with other securities. Warrants we sell with other securities may be attached to or separate from those other securities. If we issue warrants, we will do so under one or more warrant agreements between us and a warrant agent that we will name in the prospectus supplement. We have summarized selected provisions of the warrants below. This summary is not complete. If we offer any warrants, we will file the forms of warrant certificate and warrant agreement with the SEC, and you should read those documents for provisions that may be important to you. 26

The prospectus supplement relating to any warrants being offered will include specific terms relating to the offering. These terms will include some or all of the following: . the title of the warrants; . the aggregate number of warrants offered; . the designation, number and terms of the debt securities, common stock, preferred stock or other securities purchasable on exercise of the warrants, and procedures that may result in the adjustment of those numbers; . the exercise price of the warrants; . the dates or periods during which the warrants are exercisable; . the designation and terms of any securities with which the warrants are issued; . if the warrants are issued as a unit with another security, the date on and after which the warrants and the other security will be separately transferable; . if the exercise price is not payable in U.S. dollars, the foreign currency, currency unit or composite currency in which the exercise price is denominated; . any minimum or maximum amount of warrants that may be exercised at any one time; . any terms, procedures and limitations relating to the transferability, exchange or exercise of the warrants; and . any other terms of the warrants. Warrant certificates will be exchangeable for new warrant certificates of different denominations at the office indicated in the prospectus supplement. Prior to the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities subject to the warrants. Modifications We may amend the warrant agreements and the warrants without the consent of the holders of the warrants to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision, or in any other manner that will not materially and adversely affect the interests of holders of outstanding warrants. We may also modify or amend certain other terms of the warrant agreements and the warrants with the consent of the holders of not less than a majority in number of the then outstanding unexercised warrants affected. Without the consent of the holders affected, however, no modification or amendment may: . shorten the period of time during which the warrants may be exercised; or . otherwise materially and adversely affect the exercise rights of the holders of the warrants. Enforceability of Rights The warrant agent will act solely as our agent. The warrant agent will not have any duty or responsibility if we default under the warrant agreements or the warrant certificates. A warrant holder may, without the consent of 27

the warrant agent, enforce by appropriate legal action on its own behalf the holder's right to exercise the holder's warrants. 28

Plan of Distribution We may sell the offered securities in and outside the United States (1) through underwriters or dealers, (2) directly to purchasers or (3) through agents. The prospectus supplement will set forth the following information: . the terms of the offering; . the names of any underwriters or agents; . the name or names of any managing underwriter or underwriters; . the purchase price of the securities from us; . the net proceeds we will receive from the sale of the securities; . any delayed delivery arrangements; . any underwriting discounts, commissions and other items constituting underwriters' compensation; . any initial public offering price; . any discounts or concessions allowed or reallowed or paid to dealers; and . any commissions paid to agents. Sale Through Underwriters or Dealers If we use underwriters in the sale, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to various conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers. During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, in which selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time. If we use dealers in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. We will include in the prospectus supplement the names of the dealers and the terms of the transaction. Direct Sales and Sales Through Agents We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment. 29

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act of 1933 with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement. Delayed Delivery Contracts If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from various types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions the prospectus supplement describes. The prospectus supplement will describe the commission payable for solicitation of those contracts. General Information We may have agreements with the agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act of 1933, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses. Legal Matters Baker Botts L.L.P., Houston, Texas, our outside counsel, will issue an opinion about the legality of the offered securities for us. Any underwriters will be advised about other issues relating to any offering by their own legal counsel. Experts The financial statements incorporated by reference in this prospectus have been audited by Arthur Andersen LLP, independent public accountants, as indicated in their report with respect thereto, and are incorporated herein in reliance upon the authority of said firm as experts in accounting and auditing in giving said report. 30

PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14. Other Expenses of Issuance and Distribution. The following table sets forth expenses payable by U.S. Concrete, Inc. ("U.S. Concrete" or the "Company") in connection with the issuance and distribution of the securities being registered. All the amounts shown are estimates, except the SEC registration fee. SEC registration fee ............................. $ 52,800 Printing expenses ................................ * Legal fees and expenses .......................... * Accounting fees and expenses ..................... * Fees and expenses of trustee and counsel ......... * Fees and expenses of transfer agent .............. * Rating agency fees ............................... * Miscellaneous expenses ........................... * ------------ Total................................... * ============ - ------------ * To be provided by amendment Item 15. Indemnification of Directors and Officers. Delaware General Corporation Law Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director or officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by that person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A Delaware corporation may indemnify directors, officers, employees and others in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the person to be indemnified has been adjudged to be liable to the corporation. Where a director or officer is successful on the merits or otherwise in the defense of any action referred to above or in defense of any claim, issue or matter therein, the corporation must indemnify that director or officer against the expenses (including attorneys' fees) which he or she actually and reasonably incurred in connection therewith. Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which the director derived an improper personal benefit. II-1

Certificate of Incorporation and Bylaws Article Seventh of U.S. Concrete's restated certificate of incorporation states that: No director of the Corporation shall be personally liable to the Corporation or its stockholders of monetary damages for breach of fiduciary duty by such director as a director; provided, however, that this Article Eighth shall not eliminate or limit the liability of a director to the extent provided by applicable law (1) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which the director derived an improper personal benefit. No amendment to or repeal of this Article Eighth shall apply to, or have any effect on, the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. In addition, Article VI of U.S. Concrete's bylaws further provides that U.S. Concrete shall indemnify its officers, directors and employees to the fullest extent permitted by law. Indemnification Agreements and Insurance U.S. Concrete has entered into indemnification agreements with each of its executive officers and directors. These indemnification agreements generally provide the Company's directors and executive officers with contractual rights of indemnification to the same extent provided by Section 145 of the Delaware General Corporation Law and Article VI of U.S. Concrete's bylaws. Agreements the Company may enter into with underwriters, dealers and agents who participate in the distribution of securities of the Company may contain provisions relating to the indemnification of the Company's officers and directors. The Company also maintains directors' and officers' liability insurance for its directors and officers that protects them from certain losses arising from claims or charges made against them in their capacities as directors or officers of the Company.

Item 17. Undertakings. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act"); (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post- effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a II-5

court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (d) The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (e) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee under any indenture relating to the debt securities to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939 (the "Act") in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.

Exhibit 4.5 CERTIFICATE OF DESIGNATIONS of Series A Junior Participating Preferred Stock of U.S. CONCRETE, INC. Pursuant to Section 151 of the General Corporation Law of the State of Delaware U.S. CONCRETE, INC., a corporation organized and existing under the General Corporation Law of the State of Delaware, in accordance with the provisions of Section 103 thereof, DOES HEREBY CERTIFY: That pursuant to the authority vested in the Board of Directors in accordance with the provisions of the Restated Certificate of Incorporation of the said Corporation, the said Board of Directors on May 10, 1999 adopted the following resolution creating a series of 400,000 shares of Preferred Stock designated as "Series A Junior Participating Preferred Stock": RESOLVED, that pursuant to the authority vested in the Board of Directors of this Corporation in accordance with the provisions of the Restated Certificate of Incorporation, a series of Preferred Stock, par value $.001 per share, of the Corporation be and hereby is created, and that the designation and number of shares thereof and the voting and other powers, preferences and relative, participating, optional or other rights of the shares of such series and the qualifications, limitations and restrictions thereof are as follows: SERIES A JUNIOR PARTICIPATING PREFERRED STOCK 1. Designation and Amount. There shall be a series of Preferred Stock that shall be designated as "Series A Junior Participating Preferred Stock," and the number of shares constituting such series shall be 400,000. Such number of shares may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease shall reduce the number of shares of Series A Junior Participating Preferred Stock to less than the number of shares then issued and outstanding plus the number of shares issuable upon exercise of outstanding rights, options or warrants or upon conversion of outstanding securities issued by the Corporation. 1

2. Dividends and Distributions. (A) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Series A Junior Participating Preferred Stock with respect to dividends, the holders of shares of Series A Junior Participating Preferred Stock, in preference to the holders of shares of any class or series of stock of the Corporation ranking junior to the Series A Junior Participating Preferred Stock, shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on March 31, June 30, September 30 and December 31 in each year (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b) the Adjustment Number (as defined below) times the aggregate per share amount of all cash dividends, and the Adjustment Number times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value $.001 per share, of the Corporation (the "Common Stock") since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Junior Participating Preferred Stock. The "Adjustment Number" shall initially be 100. In the event the Corporation shall at any time after May 10, 1999 (the "Rights Declaration Date") (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. (B) The Corporation shall declare a dividend or distribution on the Series A Junior Participating Preferred Stock as provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. (C) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Junior Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such 2

shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share- by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. 3. Voting Rights. The holders of shares of Series A Junior Participating Preferred Stock shall have the following voting rights: (A) Each share of Series A Junior Participating Preferred Stock shall entitle the holder thereof to a number of votes equal to the Adjustment Number on all matters submitted to a vote of the stockholders of the Corporation. (B) Except as otherwise provided herein, in the Restated Certificate of Incorporation or by law, the holders of shares of Series A Junior Participating Preferred Stock, the holders of shares of any other class or series entitled to vote with the Common Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. (C)(i) If at any time dividends on any Series A Junior Participating Preferred Stock shall be in arrears in an amount equal to six quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a "default period") that shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Series A Junior Participating Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, (1) the number of Directors shall be increased by two, effective as of the time of election of such Directors as herein provided, and (2) the holders of Preferred Stock (including holders of the Series A Junior Participating Preferred Stock) upon which these or like voting rights have been conferred and are exercisable (the "Voting Preferred Stock") with dividends in arrears in an amount equal to six quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect such two Directors. (ii) During any default period, such voting right of the holders of Series A Junior Participating Preferred Stock may be exercised initially at a special meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of stockholders, and thereafter at annual meetings of stockholders, provided that such voting right shall not be exercised unless the holders of at least one-third in number of the shares of Voting Preferred Stock outstanding shall be 3

present in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Voting Preferred Stock of such voting right. (iii) Unless the holders of Voting Preferred Stock shall, during an existing default period, have previously exercised their right to elect Directors, the Board of Directors may order, or any stockholder or stockholders owning in the aggregate not less than ten percent of the total number of shares of Voting Preferred Stock outstanding, irrespective of series, may request, the calling of a special meeting of the holders of Voting Preferred Stock, which meeting shall thereupon be called by the Chairman of the Board, the President, a Vice President or the Secretary of the Corporation. Notice of such meeting and of any annual meeting at which holders of Voting Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each holder of record of Voting Preferred Stock by mailing a copy of such notice to him at his last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or, in default of the calling of such meeting within 60 days after such order or request, such meeting may be called on similar notice by any stockholder or stockholders owning in the aggregate not less than ten percent of the total number of shares of Voting Preferred Stock outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the stockholders. (iv) In any default period, after the holders of Voting Preferred Stock shall have exercised their right to elect Directors voting as a class, (x) the Directors so elected by the holders of Voting Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the class or classes of stock which elected the Director whose office shall have become vacant. References in this paragraph (C) to Directors elected by the holders of a particular class or classes of stock shall include Directors elected by such Directors to fill vacancies as provided in clause (y) of the foregoing sentence. (v) Immediately upon the expiration of a default period, (x) the right of the holders of Voting Preferred Stock as a class to elect Directors shall cease, (y) the term of any Directors elected by the holders of Voting Preferred Stock as a class shall terminate and (z) the number of Directors shall be such number as may be provided for in the Restated Certificate of Incorporation or By-Laws irrespective of any increase made pursuant to the provisions of paragraph (C) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the Restated Certificate of Incorporation or By-Laws). Any vacancies in the Board of Directors effected by the provisions of clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining Directors. (D) Except as set forth herein, holders of Series A Junior Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent 4

they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action. 4. Certain Restrictions. (A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Junior Participating Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Junior Participating Preferred Stock outstanding shall have been paid in full, the Corporation shall not (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock; (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, except dividends paid ratably on the Series A Junior Participating Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; or (iii) redeem or purchase or otherwise acquire for consideration any shares of Series A Junior Participating Preferred Stock, or any shares of stock ranking on a parity with the Series A Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of Series A Junior Participating Preferred Stock, or to all such holders and the holders of any such shares ranking on a parity therewith, upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes. (B) The Corporation shall not permit any subsidiary of the oration to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner. 5. Reacquired Shares. Any shares of Series A Junior Participating Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new 5

series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to any conditions and restrictions on issuance set forth herein. 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Series A Junior Participating Preferred Stock shall have received $10.00 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the "Series A Junior Participating Preferred Stock Liquidation Preference"). Following the payment of the full amount of the Series A Junior Participating Preferred Stock Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the "Common Adjustment") equal to the quotient obtained by dividing (i) the Series A Junior Participating Preferred Stock Liquidation Preference by (ii) the Adjustment Number. Following the payment of the full amount of the Series A Junior Participating Preferred Stock Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Junior Participating Preferred Stock and Common Stock, respectively, holders of Series A Junior Participating Preferred Stock and holders of shares of Common Stock shall, subject to the prior rights of all other series of Preferred Stock, if any, ranking prior thereto, receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Series A Junior Participating Preferred Stock and Common Stock, on a per share basis, respectively. (B) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Junior Participating Preferred Stock Liquidation Preference and the liquidation preferences of all other series of Preferred Stock, if any, that rank on a parity with the Series A Junior Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. (C) Neither the merger or consolidation of the Corporation into or with another corporation nor the merger or consolidation of any other corporation into or with the Corporation shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6, but the sale, lease or conveyance of all or substantially all the Corporation's assets shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6. 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case each share of Series A Junior Participating Preferred Stock shall at the same time be 6

similarly exchanged or changed in an amount per share equal to the Adjustment Number times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. 8. Redemption. (A) The Corporation, at its option, may redeem shares of the Series A Junior Participating Preferred Stock in whole at any time and in part from time to time, at a redemption price equal to the Adjustment Number times the current per share market price (as such term is hereinafter defined) of the Common Stock on the date of the mailing of the notice of redemption, together with unpaid accumulated dividends to the date of such redemption. The "current per share market price" on any date shall be deemed to be the average of the closing price per share of such Common Stock for the ten consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, that in the event that the current per share market price of the Common Stock is determined during a period following the announcement of (A) a dividend or distribution on the Common Stock other than a regular quarterly cash dividend or (B) any subdivision, combination or reclassification of such Common Stock and the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, shall not have occurred prior to the commencement of such ten Trading Day period, then, and in each such case, the current per share market price shall be properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sales price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange, or, if the Common Stock is not listed or admitted to trading on the New York Stock Exchange, on the principal national securities exchange on which the Common Stock is listed or admitted to trading, or, if the Common Stock is not listed or admitted to trading on any national securities exchange but sales price information is reported for such security, as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ") or such other self-regulatory organization or registered securities information processor (as such terms are used under the Securities Exchange Act of 1934, as amended) that then reports information concerning the Common Stock, or, if sales price information is not so reported, the average of the high bid and low asked prices in the over-the-counter market on such day, as reported by NASDAQ or such other entity, or, if on any such date the Common Stock is not quoted by any such entity, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Corporation. If on any such date no such market maker is making a market in the Common Stock, the fair value of the Common Stock on such date as determined in good faith by the Board of Directors of the Corporation shall be used. The term "Trading Day" shall mean a day on which the principal national securities exchange on which the Common Stock is listed or admitted to trading is open for the transaction of business, or, if the Common Stock is not listed or admitted to trading on any national securities exchange but is quoted by NASDAQ, a day on which NASDAQ reports trades, or, if the Common Stock is not so quoted, a Monday, Tuesday, Wednesday, Thursday or Friday on which banking institutions in the State of New York are not authorized or obligated by law or executive order to close. 7

(B) In the event that fewer than all the outstanding shares of the Series A Junior Participating Preferred Stock are to be redeemed, the number of shares to be redeemed shall be determined by the Board of Directors and the shares to be redeemed shall be determined by lot or pro rata as may be determined by the Board of Directors or by any other method that may be determined by the Board of Directors in its sole discretion to be equitable. (C) Notice of any such redemption shall be given by mailing to the holders of the shares of Series A Junior Participating Preferred Stock to be redeemed a notice of such redemption, first class postage prepaid, not later than the fifteenth day and not earlier than the sixtieth day before the date fixed for redemption, at their last address as the same shall appear upon the books of the Corporation. Each such notice shall state: (i) the redemption date; (ii) the number of shares to be redeemed and, if fewer than all the shares held by such holder are to be redeemed, the number of such shares to be redeemed from such holder; (iii) the redemption price; (iv) the place or places where certificates for such shares are to be surrendered for payment of the redemption price; and (v) that dividends on the shares to be redeemed will cease to accrue on the close of business on such redemption date. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the stockholder received such notice, and failure duly to give such notice by mail, or any defect in such notice, to any holder of Series A Junior Participating Preferred Stock shall not affect the validity of the proceedings for the redemption of any other shares of Series A Junior Participating Preferred Stock that are to be redeemed. On or after the date fixed for redemption as stated in such notice, each holder of the shares called for redemption shall surrender the certificate evidencing such shares to the Corporation at the place designated in such notice and shall thereupon be entitled to receive payment of the redemption price. If fewer than all the shares represented by any such surrendered certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. (D) The shares of Series A Junior Participating Preferred Stock shall not be subject to the operation of any purchase, retirement or sinking fund. 9. Ranking. The Series A Junior Participating Preferred Stock shall rank junior to all other series of the Corporation's Preferred Stock as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise, and shall rank senior to the Common Stock as to such matters. 10. Amendment. At any time that any shares of Series A Junior Participating Preferred Stock are outstanding, the Restated Certificate of Incorporation of the Corporation shall not be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of two-thirds or more of the outstanding shares of Series A Junior Participating Preferred Stock, voting separately as a class. 11. Fractional Shares. Series A Junior Participating Preferred Stock may be issued in fractions of a share that shall entitle the holder, in proportion to such holder's fractional 8

shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Participating Preferred Stock. IN WITNESS WHEREOF, the undersigned has executed this Certificate and does affirm the foregoing as true this 1st day of September, 1999. /s/ Eugene P. Martineau ------------------------------------------ Eugene P. Martineau President and Chief Executive Officer 9

The Trustee's certificate of authentication shall be in substantially the following form: "This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. 9

_________________________, as Trustee By: _____________________________________ Authorized Officer". SECTION 2.04 Execution, Authentication, Delivery and Dating. Two Officers of the Company shall sign the Securities of each series on behalf of the Company by manual or facsimile signature. The Company's seal, if any, shall be impressed, affixed, imprinted or reproduced on the Securities and may be in facsimile form. If an Officer of the Company whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless. A Security shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if any Security has been authenticated and delivered hereunder but never issued and sold by the Company, and the Company delivers that Security to the Trustee for cancellation as provided in Section 2.13 together with a written statement (which need not comply with Section 10.05 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture that Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, and the Trustee shall authenticate and deliver those Securities for original issue on a Company Order for the authentication and delivery of those Securities or pursuant to such procedures reasonably acceptable to the Trustee as may be specified from time to time by Company Order. That order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated, the name or names of the initial Holder or Holders and any other terms of the Securities of that series not otherwise determined. If provided for in those procedures, that Company Order may authorize (1) authentication and delivery of Securities of that series for original issue from time to time, with certain terms (including, without limitation, the Maturity date or dates, original issue date or dates and interest rate or rates) that differ from Security to Security and (2) may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Section 2.01, in authenticating those Securities, and accepting the additional responsibilities under this Indenture in relation to those Securities, the Trustee shall be entitled to receive (in addition to the Company Order referred to above and the other 10

documents required by Section 10.04), and (subject to Section 7.01) shall be fully protected in relying on, (a) an Officers' Certificate setting forth the Board Resolution and, if applicable, an appropriate record of any action taken pursuant thereto, as contemplated by the last paragraph of Section 2.01; and (b) an Opinion of Counsel to the effect that: (i) if the form of those Securities has been established by or pursuant to Board Resolution, as is permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture; (ii) if the terms of those Securities have been established by or pursuant to Board Resolution, as is permitted by Section 2.01, that such terms have been established in conformity with the provisions of this Indenture; and (iii) those Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in that Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws in effect from time to time affecting the rights of creditors generally, and the application of general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law). If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers' Certificate and Opinion of Counsel at the time of issuance of each such Security, but that Officers' Certificate and Opinion of Counsel shall be delivered at or before the time of issuance of the first Security of the series to be issued. The Trustee shall not be required to authenticate those Securities if the issuance of those Securities pursuant to this Indenture would affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the Trustee. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. Unless limited by the terms of that appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by that agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company. Each Security shall be dated the date of its authentication. 11

SECTION 2.05 Registrar and Paying Agent. The Company shall maintain an office or agency for each series of Securities where Securities of that series may be presented for registration of transfer or exchange ("Registrar") and an office or agency where Securities of that series may be presented for payment ("Paying Agent"). The Registrar shall keep a register of the Securities of that series and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar, and the term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to that Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. The Company may change any Paying Agent or Registrar without notice to any Holder. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. The Company initially appoints the Trustee as Registrar and Paying Agent. SECTION 2.06 Paying Agent to Hold Money in Trust. With respect to each series of Securities, the Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders of Securities of that series or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on or any Additional Amounts with respect to Securities of that series and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent with respect to a series of Securities, it shall segregate and hold in a separate trust fund for the benefit of the Holders of Securities of that series all money held by it as Paying Agent. Each Paying Agent shall otherwise comply with TIA (S) 317(b). SECTION 2.07 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of each series of Securities and shall otherwise comply with TIA (S) 312(a). If the Trustee is not the Registrar with respect to a series of Securities, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date with respect to that series of Securities, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of 12

the names and addresses of Holders of the Securities of that series, and the Company shall otherwise comply with TIA (S) 312(a). SECTION 2.08 Transfer and Exchange. Except as set forth in Section 2.17 or as may be provided pursuant to Section 2.01, when Securities of any series are presented to the Registrar with the request to register the transfer of those Securities or to exchange those Securities for an equal principal amount of Securities of the same series of like tenor and of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements and the requirements of this Indenture for those transactions are met; provided, however, that the Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instruction of transfer in form reasonably satisfactory to the Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on which instruction the Registrar can rely. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's written request and submission of the Securities (other than Global Securities). No service charge shall be made to a Holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or similar governmental charge payable on exchanges pursuant to Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part pursuant to Article III, except the unredeemed portion of any Security being redeemed in part or (b) any Security during the period beginning 15 Business Days before the mailing of notice of any offer to repurchase Securities of the series required pursuant to the terms thereof or of redemption of Securities of a series to be redeemed and ending at the close of business on the date of mailing. SECTION 2.09 Replacement Securities. If any mutilated Security is surrendered to the Trustee, or if the Holder of a Security claims that the Security has been destroyed, lost or stolen and the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of that Security, the Company shall issue and the Trustee shall authenticate a replacement Security of the same series if the Trustee's requirements are met. If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay that Security. If required by the Trustee or the Company, the Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent or any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security. Every replacement Security is an additional obligation of the Company. 13

SECTION 2.10 Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee hereunder and those described in this Section 2.10 as not outstanding. If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. SECTION 2.11 Original Issue Discount, Foreign-Currency Denominated and Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, amendment, supplement, waiver or consent, (a) the principal amount of an Original Issue Discount Security shall be the principal amount thereof that would be due and payable as of the date of that determination upon acceleration of the Maturity thereof pursuant to Section 6.02, (b) the principal amount of a Security denominated in a foreign currency shall be the Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for that currency, as that rate is certified for customs purposes by the Federal Reserve Bank of New York (the "Exchange Rate") on the date of original issuance of that Security, of the principal amount (or, in the case of an Original Issue Discount Security, the Dollar equivalent, as determined by the Company by reference to the Exchange Rate on the date of original issuance of that Security, of the amount determined as provided in (a) above), of that Security and (c) Securities owned by the Company or any other obligor on the Securities or any Affiliate of the Company or of that other obligor shall be disregarded, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, amendment, supplement, waiver or consent, only Securities that the Trustee actually knows are so owned shall be so disregarded. SECTION 2.12 Temporary Securities. Until definitive Securities of any series are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. 14

Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. SECTION 2.13 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or redemption or for credit against any sinking fund payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, redemption, replacement or cancellation or for credit against any sinking fund. Unless the Company shall direct in writing that canceled Securities be returned to it, after written notice to the Company all canceled Securities held by the Trustee shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the Trustee shall maintain a record of their disposal. The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation. SECTION 2.14 Payments; Defaulted Interest. Unless otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, interest (except defaulted interest) on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Persons who are registered Holders of that Security at the close of business on the record date next preceding that Interest Payment Date, even if those Securities are canceled after that record date and on or before that Interest Payment Date. Unless otherwise provided with respect to the Securities of any series, the Company will pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities in Dollars. Those amounts shall be payable at the offices of the Trustee, provided that at the option of the Company, the Company may pay those amounts (1) by wire transfer with respect to Global Securities or (2) by check payable in that money mailed to a Holder's registered address with respect to any Securities. If the Company defaults in a payment of interest on the Securities of any series, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities of that series and in Section 4.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special record date selected by the Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20 days' prior written notice from the Company setting forth that record date and the interest amount to be paid) shall mail to Holders of any such series of Securities a notice that states the special record date, the related payment date and the amount of that interest to be paid. SECTION 2.15 Persons Deemed Owners. The Company, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of that Security for the purpose of receiving payments of principal of, premium (if any) or interest on, or any Additional Amounts with 15

respect to that Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary. SECTION 2.16 Computation of Interest. Except as otherwise specified as contemplated by Section 2.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year comprising twelve 30-day months. SECTION 2.17 Global Securities; Book-Entry Provisions. If Securities of a series are issuable in global form as a Global Security, as contemplated by Section 2.01, then, notwithstanding clause (10) of Section 2.01 and the provisions of Section 2.02, any such Global Security shall represent those of the outstanding Securities of that series as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges or redemptions. Any endorsement of a Global Security to reflect the amount, or any increase or decrease in the amount, of outstanding Securities represented thereby shall be made by the Trustee (i) in such manner and upon instructions given by such Person or Persons as shall be specified in that Security or in a Company Order to be delivered to the Trustee pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other written form of instructions as is customary for the Depositary for that Security, from that Depositary or its nominee on behalf of any Person having a beneficial interest in that Global Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified in that Security or in the applicable Company Order. With respect to the Securities of any series that are represented by a Global Security, the Company authorizes the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the Depositary appointed with respect to that Global Security. Any Global Security may be deposited with the Depositary or its nominee, or may remain in the custody of the Trustee or the Security Custodian therefor pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee and the Depositary. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 10.05 and need not be accompanied by an Opinion of Counsel. Members of, or participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee or the Security Custodian as its custodian, or under that Global Security, and the Depositary may be treated by the Company, the Trustee or the Security Custodian and any agent of the Company, the Trustee or the Security Custodian as the absolute owner of that Global Security for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a Global Security of any series may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a 16

Holder of Securities of that series is entitled to take under this Indenture or the Securities of that series and (ii) nothing herein shall prevent the Company, the Trustee or the Security Custodian or any agent of the Company, the Trustee, or the Security Custodian from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Security. Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01, transfers of a Global Security shall be limited to transfers of that Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred in accordance with the rules and procedures of the Depositary. Securities of any series shall be transferred to all beneficial owners of a Global Security of that series in exchange for their beneficial interests in that Global Security if, and only if, either (1) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for that Global Security and a successor Depositary is not appointed by the Company within 90 days of that notice, (2) an Event of Default has occurred with respect to that series and is continuing and the Registrar has received a request from the Depositary to issue Securities of that series in lieu of all or a portion of that Global Security (in which case the Company shall deliver Securities of that series within 30 days of that request) or (3) the Company determines not to have the Securities of that series represented by a Global Security. In connection with any transfer of a portion of the beneficial interests in a Global Security to beneficial owners pursuant to this Section 2.17, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee on receipt of a Company Order for the authentication and delivery of Securities shall authenticate and deliver, one or more Securities of the same series of like tenor and amount. In connection with the transfer of all the beneficial interests in a Global Security of any series to beneficial owners pursuant to this Section 2.17, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate principal amount of Securities of that series of authorized denominations. Neither the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to those Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Global Security Holder or the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from that Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Securities to be issued). 17

The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any Global Security if that Global Security was never issued and sold by the Company and the Company delivers to the Trustee the Global Security together with written instructions (which need not comply with Section 10.05 and need not be accompanied by an Opinion of Counsel) with regard to the cancellation or reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of the third paragraph of Section 2.04. Notwithstanding the provisions of Sections 2.03 and 2.14, unless otherwise specified as contemplated by Section 2.01 with respect to Securities of any series, payment of principal of and premium (if any) and interest on and any Additional Amounts with respect to any Global Security shall be made to the Person or Persons specified therein. ARTICLE III REDEMPTION SECTION 3.01 Applicability of Article. Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 2.01 for Securities of any series) in accordance with this Article III. SECTION 3.02 Notice to the Trustee. If the Company elects to redeem Securities of any series pursuant to this Indenture, it shall notify the Trustee of the Redemption Date and principal amount of Securities of that series to be redeemed. The Company shall so notify the Trustee at least 45 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) by delivering to the Trustee an Officers' Certificate stating that the redemption will comply with the provisions of this Indenture and of the Securities of that series. Any such notice may be canceled at any time prior to the mailing of that notice of redemption to any Holder of the Securities of that series and shall thereupon be void and of no effect. SECTION 3.03 Selection of Securities To Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all of the Securities of that series of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Securities of that series (and tenor) not previously called for redemption, either pro rata, by lot or by such other method as the Trustee shall deem fair and appropriate. That redemption may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of that series of a denomination larger than the minimum authorized denomination for Securities of that series or of the principal amount of Global Securities of that series. 18

The Trustee shall promptly notify the Company and the Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities of any series shall relate, in the case of any of the Securities redeemed or to be redeemed only in part, to the portion of the principal amount thereof which has been or is to be redeemed. SECTION 3.04 Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities of a series to be redeemed, at the address of that Holder appearing in the register of Securities for that series maintained by the Registrar. All notices of redemption shall identify the Securities to be redeemed and shall state: (1) the Redemption Date; (2) the Redemption Price; (3) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of those Securities is to receive payment of the Redemption Price on surrender to the Paying Agent of the Securities redeemed; (4) if any Security is to be redeemed in part, the portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, on surrender for cancellation of that Security to the Paying Agent, a new Security or Securities in the aggregate principal amount equal to the unredeemed portion thereof will be issued without charge to the Holder; (5) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and the name and address of the Paying Agent; (6) that the redemption is for a sinking or analogous fund, if that is the case; and (7) the CUSIP number, if any, relating to those Securities. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's written request, by the Trustee in the name and at the expense of the Company. 19

SECTION 3.05 Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent, those Securities called for redemption shall be paid at the Redemption Price, but interest installments whose maturity is on or prior to that Redemption Date will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant record dates specified pursuant to Section 2.01. SECTION 3.06 Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Trustee or the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.06) an amount of money in same day funds sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on and any Additional Amounts with respect to, the Securities or portions thereof which are to be redeemed on that date, other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation. If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of that Redemption Price, interest on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not those Securities are presented for payment, and the Holders of those Securities shall have no further rights with respect to those Securities except for the right to receive the Redemption Price on surrender of those Securities. If any Security called for redemption shall not be so paid on surrender thereof for redemption, the principal of and premium, if any, any Additional Amounts, and, to the extent lawful, accrued interest thereon shall, until paid, bear interest from the Redemption Date at the rate specified pursuant to Section 2.01 or provided in the Securities or, in the case of Original Issue Discount Securities, their initial yield to maturity. SECTION 3.07 Securities Redeemed or Purchased in Part. Upon surrender to the Paying Agent of a Security to be redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of that Security without service charge a new Security or Securities, of the same series and of any authorized denomination as requested by that Holder in aggregate principal amount equal to, and in exchange for, the unredeemed portion of the principal of the Security so surrendered that is not redeemed. SECTION 3.08 Purchase of Securities. Unless otherwise specified as contemplated by Section 2.01, the Company and any Affiliate of the Company may at any time purchase or otherwise acquire Securities in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a redemption of the indebtedness represented by those Securities. Any Securities purchased or acquired by the Company may be delivered to the Trustee for cancellation and, on that 20

cancellation, the indebtedness represented thereby shall be deemed to be satisfied. Section 2.13 shall apply to all Securities so delivered. SECTION 3.09 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment," and any payment in excess of the minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment." Unless otherwise provided by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.10. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of that series and by this Article III. SECTION 3.10 Satisfaction of Sinking Fund Payments with Securities. The Company may deliver outstanding Securities of a series (other than any previously called for redemption) and may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms of those Securities or through the application of permitted optional sinking fund payments pursuant to the terms of those Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of that series required to be made pursuant to the terms of that series of Securities; provided that those Securities have not been previously so credited. Those Securities shall be received and credited for that purpose by the Trustee at the Redemption Price specified in those Securities for redemption through operation of the sinking fund, and the amount of that sinking fund payment shall be reduced accordingly. SECTION 3.11 Redemption of Securities for Sinking Fund. Not less than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate of the Company specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, that is to be satisfied by payment of cash and the portion thereof, if any, that is to be satisfied by delivery of or by crediting Securities of that series pursuant to Section 3.10 and will also deliver to the Trustee any Securities to be so delivered. Failure of the Company to timely deliver that Officers' Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute the election of the Company (i) that the mandatory sinking fund payment for that series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of that series in respect thereof and (ii) that the Company will make no optional sinking fund payment with respect to that series as provided in this Section. If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $100,000 (or the Dollar equivalent thereof based on the applicable Exchange Rate on the date of original issue of the applicable Securities) or a lesser 21

sum if the Company shall so request with respect to the Securities of any particular series, that cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of that series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If that amount shall be $100,000 (or the Dollar equivalent thereof as aforesaid) or less and the Company makes no such request, then it shall be carried over until a sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is available. Not less than 30 days before each such sinking fund payment date, the Trustee shall select the Securities to be redeemed on that sinking fund payment date in the manner specified in Section 3.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.04. That notice having been duly given, the redemption of those Securities shall be made on the terms and in the manner stated in Sections 3.05, 3.06 and 3.07. ARTICLE IV COVENANTS SECTION 4.01 Payment of Securities. The Company shall pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of each series on the dates and in the manner provided in the Securities of that series and in this Indenture. Principal, premium, interest and any Additional Amounts shall be considered paid on the date due if the Paying Agent, other than the Company or a Subsidiary of the Company, holds on that date money deposited by the Company designated for and sufficient to pay all principal, premium (if any), interest and any Additional Amounts then due. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal of and premium (if any) on Securities of any series, at a rate equal to the then applicable interest rate on the Securities of that series to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest on and any overdue payments of Additional Amounts with respect to Securities of that series (without regard to any applicable grace period) at the same rate to the extent lawful. SECTION 4.02 Maintenance of Office or Agency. The Company will maintain in each Place of Payment for any series of Securities an office or agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities of that series may be presented for registration of transfer or exchange, where Securities of that series may be presented for payment and where notices and demands to or on the Company in respect of the Securities of that series and this Indenture may be served. Unless otherwise designated by the Company by written notice to the Trustee, that office or agency shall be the office of the Trustee in The City of New York, which on the date hereof is located at ____________________. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of that office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the 22

address thereof, those presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all those purposes and may from time to time rescind those designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for those purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. SECTION 4.03 SEC Reports; Financial Statements. (a) The Company shall file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports (or copies of those portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company shall also comply with the provisions of TIA (S) 314(a). (b) If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall furnish to all Holders of Rule 144A Securities and prospective purchasers of Rule 144A Securities designated by the Holders of Rule 144A Securities, promptly on their request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the Securities Act of 1933, as amended. SECTION 4.04 Compliance Certificate. (a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a statement signed by an Officer of the Company, which need not constitute an Officers' Certificate, complying with TIA (S) 314(a)(4) and stating that, in the course of performance by the signing Officer of the Company of his or her duties as such Officer of the Company, he or she would normally obtain knowledge of the keeping, observing, performing and fulfilling by the Company of its obligations under this Indenture, and further stating that, to the best of his or her knowledge, the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which that Officer may have knowledge and what action the Company is taking or proposes to take with respect thereto). (b) The Company shall, so long as Securities of any series are outstanding, deliver to the Trustee, promptly on any Officer of the Company becoming aware of any Default or Event of Default under this Indenture, an Officers' Certificate specifying that Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 23

SECTION 4.05 Existence. Subject to Article V hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Subsidiaries and all rights (charter and statutory) of the Company and its Subsidiaries, provided that the Company shall not be required to preserve the existence of any Subsidiary of the Company or any such right if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries taken as a whole and that the loss thereof would not have a material adverse effect on the business, operations, assets or financial condition of the Company and its Subsidiaries taken as a whole and would not have any material adverse effect on the payment and performance of the obligations of the Company under the Securities and this Indenture. SECTION 4.06 Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist on, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.07 Additional Amounts. If the Securities of a series expressly provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of that series Additional Amounts as expressly provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received from the sale or exchange of any Security of any series, that mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.07 to the extent that, in that context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 4.07, and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where that express mention is not made. Unless otherwise provided pursuant to Section 2.01 with respect to Securities of any series, if the Securities of a series provide for the payment of Additional Amounts, at least ten days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least ten days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish the Trustee and the Company's 24

principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether that payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then that Officers' Certificate shall specify by country the amount, if any, required to be withheld on those payments to those Holders of Securities, and the Company will pay to that Paying Agent the Additional Amounts required by this Section. The Company covenants to indemnify the Trustee and any Paying Agent for and to hold them harmless against any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this Section 4.07. ARTICLE V SUCCESSORS SECTION 5.01 Limitations on Mergers, Consolidations and Other Transactions. The Company shall not, in any transaction or series of related transactions, consolidate with any other Person into, or merge into, any other Person, or sell, lease, convey, transfer or otherwise dispose of its assets substantially as an entirety to any Person, unless: (1) the Person formed by that consolidation or into which the Company is merged, or to which that sale, lease, conveyance, transfer or other disposition shall be made (collectively, the "Successor"), is organized and validly existing under the laws of the United States, any political subdivision thereof or any State thereof or the District of Columbia, and expressly assumes by supplemental indenture the due and punctual payment of the principal of (and premium, if any) and interest on and Additional Amounts with respect to all the Securities and the performance of the Company's covenants and obligations under this Indenture and the Securities; (2) immediately after giving effect to that transaction or series of related transactions, no Default or Event of Default shall have occurred and be continuing; and (3) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that the transaction and that supplemental indenture comply with this Indenture. SECTION 5.02 Successor Person Substituted. Upon any consolidation or merger of the Company or any sale, lease, conveyance, transfer or other disposition of the assets of the Company substantially as an entirety in accordance with Section 5.01, any Successor formed by that consolidation or into or with which the Company is merged or to which that sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of the Company under this 25

Indenture and the Securities with the same effect as if that Successor had been named as the Company herein and the predecessor Company, in the case of a sale, conveyance, transfer or other disposition, shall be released from all obligations under this Indenture and the Securities. ARTICLE VI DEFAULTS AND REMEDIES SECTION 6.01 Events of Default. Unless either inapplicable to a particular series or specifically deleted or modified in or pursuant to the supplemental indenture or Board Resolution establishing that series of Securities or in the form of Security for that series, an "Event of Default," wherever used herein with respect to Securities of any series, occurs if: (1) the Company defaults in the payment of interest on or any Additional Amounts with respect to any Security of that series when the same becomes due and payable and that default continues for a period of 30 days; (2) the Company defaults in the payment of (A) the principal of any Security of that series at its Maturity or (B) premium (if any) on any Security of that series when the same becomes due and payable; (3) the Company defaults in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series, and that default continues for a period of 30 days; (4) the Company fails to comply with any of its other covenants or agreements in, or provisions of, the Securities of that series or this Indenture (other than an agreement, covenant or provision that has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than that series) which shall not have been remedied within the specified period after written notice, as specified in the last paragraph of this Section 6.01; (5) the Company pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors; 26

(6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 90 days and that: (A) is for relief against the Company as debtor in an involuntary case, (B) appoints a Bankruptcy Custodian of the Company or a Bankruptcy Custodian for all or substantially all of the property of the Company, or (C) orders the liquidation of the Company; or (7) any other Event of Default provided with respect to Securities of that series occurs. The term "Bankruptcy Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. The Trustee shall not be deemed to know or have notice of a Default unless a Trust Officer at the Corporate Trust Office of the Trustee receives written notice at the Corporate Trust Office of the Trustee of that Default with specific reference to that Default. When a Default is cured, it ceases. Notwithstanding the foregoing provisions of this Section 6.01, if the principal of, premium (if any) or interest on or Additional Amounts with respect to any Security is payable in a currency or currencies (including a composite currency) other than Dollars and such currency or currencies are not available to the Company for making payment thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company (a "Conversion Event"), the Company will be entitled to satisfy its obligations to Holders of the Securities by making that payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other currency, as determined by the Company by reference to the Exchange Rate on the date of that payment, or, if that rate is not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the foregoing provisions of this Section 6.01, any payment made under such circumstances in Dollars where the required payment is in a currency other than Dollars will not constitute an Event of Default under this Indenture. Promptly after the occurrence of a Conversion Event, the Company shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of that notice, shall give notice thereof in the manner provided in Section 10.02 to the Holders. Promptly after the making of any payment in Dollars as a result of a Conversion Event, the Company shall give notice in the manner provided in Section 10.02 to the Holders, setting forth the applicable Exchange Rate and describing the calculation of those payments. A Default under clause (4) or (7) of this Section 6.01 is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by that Default (or, in the case of a Default under clause 27

(4) of this Section 6.01, if outstanding Securities of other series are affected by that Default, then at least 25% in principal amount of the then outstanding Securities so affected) notify the Company and the Trustee, of the Default, and the Company fails to cure the Default within 90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." SECTION 6.02 Acceleration. If an Event of Default with respect to any Securities of any series at the time outstanding (other than an Event of Default specified in clause (5) or (6) of Section 6.01 hereof) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by that default (or, in the case of an Event of Default described in clause (4) of Section 6.01, if outstanding Securities of other series are affected by that Default, then at least 25% in principal amount of the then outstanding Securities so affected) by notice to the Company and the Trustee, may declare the principal of (or, if any of those Securities are Original Issue Discount Securities, that portion of the principal amount as may be specified in the terms of that series) and all accrued and unpaid interest on all then outstanding Securities of that series or of all series, as the case may be, to be due and payable. Upon any such declaration, the amounts due and payable on those Securities shall be due and payable immediately. If an Event of Default specified in clause (5) or (6) of Section 6.01 hereof occurs, those amounts shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities of the series affected by that default or all series, as the case may be, by written notice to the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of or premium or interest on or any Additional Amounts with respect to the Securities) if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to Securities of that series (or of all series, as the case may be) have been cured or waived, except nonpayment of principal, premium, interest or any Additional Amounts that has become due solely because of the acceleration. SECTION 6.03 Other Remedies. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on the Securities of that series or to enforce the performance of any provision of the Securities of that series or this Indenture. The Trustee may maintain a proceeding with respect to Securities of any series even if it does not possess any of the Securities of that series or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing on an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 28

SECTION 6.04 Waiver of Defaults. Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the then outstanding Securities of any series or of all series (acting as one class) by notice to the Trustee may waive an existing or past Default or Event of Default with respect to that series or all series, as the case may be, and its consequences (including waivers obtained in connection with a tender offer or exchange offer for Securities of that series or all series or a solicitation of consents in respect of Securities of that series or all series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of that series or all series (but the terms of that offer or solicitation may vary from series to series)), except (1) a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on or any Additional Amounts with respect to any Security or (2) a continued Default in respect of a provision that under Section 9.02 cannot be amended or supplemented without the consent of each Holder affected. Upon any such waiver, that Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. SECTION 6.05 Control by Majority. With respect to Securities of any series, the Holders of a majority in principal amount of the then outstanding Securities of that series may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it relating to or arising under an Event of Default described in clause (1), (2), (3) or (7) of Section 6.01, and with respect to all Securities, the Holders of a majority in principal amount of all the then outstanding Securities affected may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it not relating to or arising under such an Event of Default. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with that direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion from Holders directing the Trustee against all losses and expenses caused by taking or not taking that action. SECTION 6.06 Limitations on Suits. Subject to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy with respect to this Indenture or the Securities of that series only if: (1) the Holder gives to the Trustee written notice of a continuing Event of Default with respect to that series; (2) the Holders of at least 25% in principal amount of the then outstanding Securities of that series make a written request to the Trustee to pursue the remedy; 29

(3) such Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and (5) during that 60-day period, the Holders of a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent with the request. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of and premium, if any, and interest on and any Additional Amounts with respect to that Security, on or after the respective due dates expressed in that Security, or to bring suit for the enforcement of any such payment on or after those respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. SECTION 6.08 Collection Suit by Trustee. If an Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs and is continuing with respect to Securities of any series, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the amount of principal, premium (if any), interest and any Additional Amounts remaining unpaid on the Securities of that series, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, as may be necessary or advisable to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceeding relative to the Company or its creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Bankruptcy Custodian in any such judicial proceeding is hereby authorized by each Holder to make those payments to the Trustee, and in the event that the Trustee shall consent to the making of those payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, 30

disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties which the Holders of the Securities may be entitled to receive in that proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10 Priorities. If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07; Second: to Holders for amounts due and unpaid on the Securities in respect of which or for the benefit of which that money has been collected, for principal, premium (if any), interest and any Additional Amounts ratably, without preference or priority of any kind, according to the amounts due and payable on those Securities for principal, premium (if any), interest and any Additional Amounts, respectively; and Third: to the Company. The Trustee, on prior written notice to the Company, may fix record dates and payment dates for any payment to Holders pursuant to this Article VI. To the fullest extent allowed under applicable law, if for the purpose of obtaining a judgment against the Company in any court it is necessary to convert the sum due in respect of the principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities of any series (the "Required Currency") into a currency in which a judgment will be rendered (the "Judgment Currency"), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Business Day next preceding that on which final judgment is given. Neither the Company nor the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to Holders of Securities under this Section 6.10 caused by a change in exchange rates between the time the amount of a judgment against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required Currency to make payments under this Section to Holders of Securities, but payment of that judgment shall discharge all amounts owed by the Company on the claim or claims underlying that judgment. 31

SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the then outstanding Securities of any series. ARTICLE VII TRUSTEE SECTION 7.01 Duties of Trustee. (a) If an Event of Default with respect to the Securities of any series has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to the Securities of that series, and use the same degree of care and skill in that exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of an Event of Default with respect to the Securities of any series: (1) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, on certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine those certificates and opinions to determine whether, on their face, they appear to conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: (1) this paragraph does not limit the effect of Section 7.01(b); (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 32

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.01. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity reasonably satisfactory to it against any loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee with respect to Securities of any series shall, until applied as herein provided, be held in trust for the payment of the principal of, premium (if any) and interest on and Additional Amounts with respect to the Securities of that series. SECTION 7.02 Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may require instruction, an Officers' Certificate or an Opinion of Counsel or both to be provided. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on that instruction, Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel, and the written advice of that counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers conferred on it by this Indenture. (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. 33

SECTION 7.03 May Hold Securities. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. However, the Trustee is subject to Sections 7.10 and 7.11. SECTION 7.04 Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities; it shall not be accountable for the Company's use of the proceeds from the Securities or any money paid to the Company or upon the Company's direction under any provision hereof; it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee; and it shall not be responsible for any statement or recital herein or any statement in the Securities other than its certificate of authentication. SECTION 7.05 Notice of Defaults. If a Default or Event of Default with respect to the Securities of any series occurs and is continuing and it is known to the Trustee, the Trustee shall mail to Holders of Securities of that series a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium (if any) and interest on and Additional Amounts or any sinking fund installment with respect to the Securities of that series, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders of Securities of that series. SECTION 7.06 Reports by Trustee to Holders. Within 60 days after each May 15 of each year after the execution of this Indenture, the Trustee shall mail to Holders of a series and the Company a brief report dated as of that reporting date that complies with TIA (S) 313(a); provided, however, that if no event described in TIA (S) 313(a) has occurred within the twelve months preceding the reporting date with respect to a series, no report need be transmitted to Holders of that series. The Trustee also shall comply with TIA (S) 313(b). The Trustee shall also transmit by mail all reports if and as required by TIA (S)(S) 313(c) and 313(d). A copy of each report at the time of its mailing to Holders of a series of Securities shall be filed by the Company with the SEC and each securities exchange, if any, on which the Securities of that series are listed. The Company shall notify the Trustee if and when any series of Securities is listed on any stock exchange. SECTION 7.07 Compensation and Indemnity. The Company agrees to pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The 34

Company agrees to reimburse the Trustee on request for all reasonable disbursements, advances and expenses incurred by it. Those expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company hereby indemnifies the Trustee against any loss, liability or expense incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, except as set forth in the next paragraph. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel, and the Company shall pay the reasonable fees and expenses of that counsel. The Company need not pay for any settlement made without its consent. The Company shall not be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through negligence or bad faith. To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of any series. That lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(5) or (6) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.08 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 7.08. The Trustee may resign and be discharged at any time with respect to the Securities of one or more series by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee with respect to the Securities of that series by so notifying the Trustee and the Company. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its property; or 35

(4) the Trustee otherwise becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, with respect to the Securities of one or more series, the Company shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of those series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). Within one year after the successor Trustee with respect to the Securities of any series takes office, the Holders of a majority in principal amount of the Securities of that series may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee with respect to the Securities of any series does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the then outstanding Securities of that series may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of that series. If the Trustee with respect to the Securities of a series fails to comply with Section 7.10, any Holder of Securities of that series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Securities of that series. In case of the appointment of a successor Trustee with respect to all Securities, each such successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. In case of the appointment of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more (but not all) series shall execute and deliver an indenture supplemental hereto in which each successor Trustee shall accept that appointment and that (1) shall confer to each successor Trustee all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall confirm that all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee. Nothing herein or in that supplemental indenture shall constitute those Trustees co-trustees of the same trust, and each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. Upon the execution and delivery of that 36

supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, and each such successor Trustee shall have all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates. On the request of the Company or any successor Trustee, that retiring Trustee shall transfer to that successor Trustee all property held by that retiring Trustee as Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates. Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 7.08, the obligations of the Company under Section 7.07 shall continue for the benefit of the retiring Trustee or Trustees. SECTION 7.09 Successor Trustee by Merger, etc. Subject to Section 7.10, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee corporation expressly assumes all of the Trustee's liabilities hereunder. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to that authenticating Trustee may adopt that authentication and deliver the Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate those Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all those cases those certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. SECTION 7.10 Eligibility; Disqualification. There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under the laws of the United States, any State thereof or the District of Columbia and authorized under those laws to exercise corporate trust power, shall be subject to supervision or examination by Federal or State (or the District of Columbia) authority and shall have, or be a Subsidiary of a bank or bank holding company having, a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. The Indenture shall always have a Trustee who satisfies the requirements of TIA (S)(S) 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA (S) 310(b) during the period of time required by this Indenture. Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA (S) 310(b). 37

SECTION 7.11 Preferential Collection of Claims Against Company. The Trustee is subject to and shall comply with the provisions of TIA (S) 311(a), excluding any creditor relationship listed in TIA (S) 311(b). A Trustee who has resigned or been removed shall be subject to TIA (S) 311(a) to the extent indicated therein. ARTICLE VIII DISCHARGE OF INDENTURE SECTION 8.01 Termination of Company's Obligations. (a) This Indenture shall cease to be of further effect with respect to the Securities of a series (except that the Company's obligations under Section 7.07, the Trustee's and Paying Agent's obligations under Section 8.03 and the rights, powers, protections and privileges accorded the Trustee under Article VII shall survive), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging the satisfaction and discharge of this Indenture with respect to the Securities of that series, when: (1) either (A) all outstanding Securities of that series theretofore authenticated and issued (other than destroyed, lost or stolen Securities that have been replaced or paid) have been delivered to the Trustee for cancellation; or (B) all outstanding Securities of that series not theretofore delivered to the Trustee for cancellation: (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and, in the case of clause (i), (ii) or (iii) above, the Company has irrevocably deposited or caused to be deposited with the Trustee as funds (immediately available to the Holders in the case of clause (i)) in trust for that purpose (x) cash in an amount, or (y) Government Obligations, maturing as to principal and interest at such times and in such amounts as will ensure the availability of cash in an amount or (z) a combination thereof, which will be sufficient, in the opinion (in the case of clauses (y) and (z)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and 38

discharge the entire indebtedness on the Securities of that series for principal and any interest and any Additional Amounts to the date of that deposit (in the case of Securities which have become due and payable) or for principal, premium, if any, interest and any Additional Amounts to the Stated Maturity or Redemption Date, as the case may be; or (C) the Company has properly fulfilled such other means of satisfaction and discharge as is specified, as contemplated by Section 2.01, to be applicable to the Securities of that series; (2) the Company has paid or caused to be paid all other sums payable by it hereunder with respect to the Securities of that series; and (3) the Company has delivered to the Trustee an Officers' Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture with respect to the Securities of that series have been complied with, together with an Opinion of Counsel to the same effect. (b) Unless this Section 8.01(b) is specified as not being applicable to Securities of a series as contemplated by Section 2.01, the Company may terminate certain of its obligations under this Indenture ("covenant defeasance") with respect to the Securities of a series if: (1) the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for and dedicated solely to the benefit of the Holders of Securities of that series, (i) money in the currency in which payment of the Securities of that series is to be made in an amount, or (ii) Government Obligations with respect to that series, maturing as to principal and interest at such times and in such amounts as will ensure the availability of money in the currency in which payment of the Securities of that series is to be made in an amount or (iii) a combination thereof, that is sufficient, in the opinion (in the case of clauses (ii) and (iii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay, without consideration of the reinvestment of any such amounts and after payment of all taxes or other charges or assessments in respect thereof payable by the Trustee, the principal of and premium (if any) and interest on and any Additional Amounts with respect to all Securities of that series on each date that such principal, premium (if any), interest or Additional Amounts are due and payable and (at the Stated Maturity thereof or on redemption as provided in Section 8.01(e)) to pay all other sums payable by it hereunder; provided that the Trustee shall have been irrevocably instructed to apply that money and/or the proceeds of those Government Obligations to the payment of said principal, premium (if any), interest and Additional Amounts with respect to the Securities of that series as the same shall become due; (2) the Company has delivered to the Trustee an Officers' Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture with respect to the 39

Securities of that series have been complied with, and an Opinion of Counsel to the same effect; (3) no Default or Event of Default with respect to the Securities of that series shall have occurred and be continuing on the date of that deposit; (4) the Company shall have delivered to the Trustee an Opinion of Counsel from counsel reasonably acceptable to the Trustee or a tax ruling to the effect that the Holders of Securities of that series will not recognize income, gain or loss for Federal income tax purposes as a result of the Company's exercise of its option under this Section 8.01(b) and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if that option had not been exercised; (5) the Company has complied with any additional conditions specified pursuant to Section 2.01 to be applicable to the discharge of Securities of that series pursuant to this Section 8.01; and (6) that deposit and discharge shall not cause the Trustee to have a conflicting interest as defined in TIA (S) 310(b). In that event, this Indenture shall cease to be of further effect (except as set forth in this paragraph), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging satisfaction and discharge under this Indenture. However, the Company's obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 5.01, 7.07, 7.08 and 8.04, the Trustee's and Paying Agent's obligations in Section 8.03 and the rights, powers, protections and privileges accorded the Trustee under Article VII shall survive until all Securities of that series are no longer outstanding. Thereafter, only the Company's obligations in Section 7.07 and the Trustee's and Paying Agent's obligations in Section 8.03 shall survive with respect to Securities of that series. After making the irrevocable deposit pursuant to this Section 8.01(b) and following satisfaction of the other conditions set forth herein, the Trustee on request shall acknowledge in writing the discharge of the Company's obligations under this Indenture with respect to the Securities of that series, except for those surviving obligations specified above. In order to have money available on a payment date to pay principal of or premium (if any) or interest on or any Additional Amounts with respect to the Securities, the Government Obligations shall be payable as to principal or interest on or before that payment date in such amounts as will provide the necessary money. Any such Government Obligations shall not be callable at the issuer's option. (c) If the Company has previously complied or is concurrently complying with Section 8.01(b) (other than any additional conditions specified pursuant to Section 2.01 that are expressly applicable only to covenant defeasance) with respect to Securities of a series, then, unless this Section 8.01(c) is specified as not being applicable to Securities of that series as contemplated 40

by Section 2.01, the Company may elect to be discharged ("legal defeasance") from its obligations to make payments with respect to Securities of that series, if: (1) no Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof shall have occurred at any time during the period ending on the 91st day after the date of deposit contemplated by Section 8.01(b) (it being understood that this condition shall not be deemed satisfied until the expiration of that period); (2) unless otherwise specified with respect to Securities of that series as contemplated by Section 2.01, the Company has delivered to the Trustee an Opinion of Counsel from counsel reasonably acceptable to the Trustee to the effect referred to in Section 8.01(b)(4) with respect to that legal defeasance, which opinion is based on (i) a private ruling of the Internal Revenue Service addressed to the Company, (ii) a published ruling of the Internal Revenue Service or (iii) a change in the applicable federal income tax law (including regulations) after the date of this Indenture; (3) the Company has complied with any other conditions specified pursuant to Section 2.01 to be applicable to the legal defeasance of Securities of that series pursuant to this Section 8.01(c); and (4) the Company has delivered to the Trustee a Company Request requesting legal defeasance of the Securities of that series and an Officers' Certificate stating that all conditions precedent with respect to legal defeasance of the Securities of that series have been complied with, together with an Opinion of Counsel to the same effect. In that event, the Company will be discharged from its obligations under this Indenture and the Securities of that series to pay principal of, premium (if any) and interest on, and any Additional Amounts with respect to, Securities of that series, the Company's obligations under Sections 4.01, 4.02 and 5.01 shall terminate with respect to those Securities, and the entire indebtedness of the Company evidenced by those Securities shall be deemed paid and discharged. (d) If and to the extent additional or alternative means of satisfaction, discharge or defeasance of Securities of a series are specified to be applicable to that series as contemplated by Section 2.01, the Company may terminate any or all of its obligations under this Indenture with respect to Securities of a series and any or all of its obligations under the Securities of that series if it fulfills such other means of satisfaction and discharge as may be so specified, as contemplated by Section 2.01, to be applicable to the Securities of that series. (e) If Securities of any series subject to subsections (a), (b), (c) or (d) of this Section 8.01 are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory or optional sinking fund provisions, the terms of the applicable trust arrangement shall provide for that redemption, and the Company shall make such arrangements as are reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 41

SECTION 8.02 Application of Trust Money. The Trustee or a trustee reasonably satisfactory to the Trustee and the Company shall hold in trust money or Government Obligations deposited with it pursuant to Section 8.01 hereof. It shall apply the deposited money and the money from Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of the series with respect to which the deposit was made. SECTION 8.03 Repayment to Company. The Trustee and the Paying Agent shall promptly pay to the Company at any time on the written request of the Company any excess money or Government Obligations (or proceeds therefrom) held by them. Subject to the requirements of any applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Company on written request any money held by them for the payment of principal, premium (if any), interest or any Additional Amounts that remain unclaimed for two years after the date on which that payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the Paying Agent with respect to that money shall cease. SECTION 8.04 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or Government Obligations deposited with respect to Securities of any series in accordance with Section 8.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting that application, the obligations of the Company under this Indenture with respect to the Securities of that series and under the Securities of that series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money or Government Obligations in accordance with Section 8.01; provided, however, that if the Company has made any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of those Securities to receive such payment from the money or Government Obligations held by the Trustee or the Paying Agent. ARTICLE IX SUPPLEMENTAL INDENTURES AND AMENDMENTS SECTION 9.01 Without Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities or waive any provision hereof or thereof without the consent of any Holder: 42

(1) to cure any ambiguity, omission, defect or inconsistency; (2) to comply with Section 5.01; (3) to provide for uncertificated Securities in addition to or in place of certificated Securities, or to provide for the issuance of bearer Securities (with or without coupons); (4) to provide any security for any series of Securities or to add guarantees of any series of Securities; (5) to comply with any requirement in order to effect or maintain the qualification of this Indenture under the TIA; (6) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if those covenants are to be for the benefit of less than all series of Securities, stating that those covenants are expressly being included solely for the benefit of that series), or to surrender any right or power herein conferred on the Company; (7) to add any additional Events of Default with respect to all or any series of the Securities (and, if any such Event of Default is applicable to less than all series of Securities, specifying the series to which that Event of Default is applicable); (8) to change or eliminate any of the provisions of this Indenture; provided that any such change or elimination shall become effective only when there is no outstanding Security of any series created prior to the execution of that amendment or supplemental indenture that is adversely affected in any material respect by that change in or elimination of that provision; (9) to establish the form or terms of Securities of any series as permitted by Section 2.01; (10) to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Section 8.01; provided, however, that any such action shall not adversely affect the interest of the Holders of Securities of that series or any other series of Securities in any material respect; or (11) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 7.08. Upon the request of the Company, accompanied by a Board Resolution, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to 43

Section 9.06, join with the Company in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained. SECTION 9.02 With Consent of Holders. Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture with the written consent (including consents obtained in connection with a tender offer or exchange offer for Securities of any one or more series or all series or a solicitation of consents in respect of Securities of any one or more series or all series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of each such series (but the terms of that offer or solicitation may vary from series to series)) of the Holders of at least a majority in principal amount of the then outstanding Securities of all series affected by that amendment or supplement (acting as one class). Upon the request of the Company, accompanied by a Board Resolution, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company in the execution of that amendment or supplemental indenture. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if that consent approves the substance thereof. The Holders of a majority in principal amount of the then outstanding Securities of one or more series or of all series may waive compliance in a particular instance by the Company with any provision of this Indenture with respect to Securities of that series (including waivers obtained in connection with a tender offer or exchange offer for Securities of that series or a solicitation of consents in respect of Securities of that series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of that series (but the terms of that offer or solicitation may vary from series to series)). However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not: (1) reduce the amount of Securities whose Holders must consent to an amendment, supplement or waiver; (2) reduce the rate of or change the time for payment of interest, including default interest, on any Security; (3) reduce the principal of, premium on or any mandatory sinking fund payment with respect to, or change the Stated Maturity of, any Security or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable on a declaration of acceleration of the Maturity thereof pursuant to Section 6.02; 44

(4) reduce the premium, if any, payable on the redemption of any Security or change the time at which any Security may or shall be redeemed; (5) change any obligation of the Company to pay Additional Amounts with respect to any Security; (6) change the coin or currency or currencies (including composite currencies) in which any Security or any premium, interest or Additional Amounts with respect thereto are payable; (7) impair the right to institute suit for the enforcement of any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Security pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06; (8) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of this Indenture pursuant to Section 6.04 or 6.07 or make any change in this sentence of Section 9.02; or (9) waive a continuing Default or Event of Default in the payment of principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities. A supplemental indenture that changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of that series with respect to that covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from that Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which that consent is required or sought as of a date identified by the Company in a notice furnished to Holders in accordance with the terms of this Indenture. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail that notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. SECTION 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect. 45

SECTION 9.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his or her Security or portion of a Security if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. The Company may, but shall not be obligated to, fix a record date (which need not comply with Section 316(c) of the TIA) for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at that record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to that amendment, supplement or waiver or to revoke any consent previously given, whether or not those Persons continue to be Holders after that record date. No consent shall be valid or effective for more than 90 days after that record date unless consents from Holders of the principal amount of Securities required hereunder for that amendment or waiver to be effective shall have also been given and not revoked within that 90-day period. After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (9) of Section 9.02 hereof. In that case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder's Security. Section 9.05 Notation on or Exchange of Securities. If an amendment or supplement changes the terms of an outstanding Security, the Company may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security at the request of the Company regarding the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of that amendment or supplement. Securities of any series authenticated and delivered after the execution of any amendment or supplement may, and shall if required by the Company, bear a notation in form approved by the Company as to any matter provided for in that amendment or supplement. Section 9.06 Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or supplement authorized pursuant to this Article if the amendment or supplement does not adversely affect the rights, duties, liabilities or 46

immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign that amendment or supplement, the Trustee shall be entitled to receive, and, subject to Section 7.01 hereof, shall be fully protected in relying on, an Opinion of Counsel provided at the expense of the Company as conclusive evidence that such amendment or supplement is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding on the Company in accordance with its terms. ARTICLE X MISCELLANEOUS Section 10.01 Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by operation of TIA (S) 318(c), the imposed duties shall control. Section 10.02 Notices. Any notice or communication by the Company or the Trustee to the other is duly given if in writing and delivered in person or mailed by first-class mail (registered or certified, return receipt requested), telex, facsimile or overnight air courier guaranteeing next day delivery, to the other's address: If to the Company: U.S. Concrete, Inc. 1300 Post Oak Blvd., Suite 1220 Houston, Texas 77056 Attention: General Counsel If to the Trustee: ______________________________ ______________________________ ______________________________ ______________________________ The Company or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications. All notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt acknowledged, if by facsimile; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery. 47

Any notice or communication to a Holder shall be mailed by first-class mail, postage prepaid, to the Holder's address shown on the register kept by the Registrar. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it, except in the case of notice to the Trustee, it is duly given only when received. If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time. All notices or communications, including without limitation notices to the Trustee or the Company by Holders, shall be in writing, except as otherwise set forth herein. In case by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impossible to mail any notice required by this Indenture, then such method of notification as shall be made with the approval of the Trustee shall constitute a sufficient mailing of that notice. SECTION 10.03 Communication by Holders with Other Holders. Holders may communicate pursuant to TIA (S) 312(b) with other Holders with respect to their rights under this Indenture or the Securities. The Company, the Trustee, the Registrar and anyone else shall have the protection of TIA (S) 312(c). SECTION 10.04 Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Company to the Trustee to take any action under this Indenture, the Company shall, if requested by the Trustee, furnish to the Trustee at the expense of the Company: (1) an Officers' Certificate (which shall include the statements set forth in Section 10.05) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and (2) an Opinion of Counsel (which shall include the statements set forth in Section 10.05 hereof) stating that, in the opinion of that counsel, all those conditions precedent and covenants have been complied with. 48

SECTION 10.05 Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA (S) 314(a)(4)) shall comply with the provisions of TIA (S) 314(e) and shall include: (1) a statement that the Person making that certificate or opinion has read that covenant or condition; (2) a brief statement as to the nature and scope of the examination or investigation on which the statements or opinions contained in that certificate or opinion are based; (3) a statement that, in the opinion of that Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not that covenant or condition has been complied with; and (4) a statement as to whether or not, in the opinion of that Person, that condition or covenant has been complied with. SECTION 10.06 Rules by Trustee and Agents. The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or the Paying Agent may make reasonable rules and set reasonable requirements for its functions. SECTION 10.07 Legal Holidays. If a payment date is a Legal Holiday at a Place of Payment, payment may be made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. Section 10.08 No Recourse Against Others. A director, officer, employee, stockholder, partner or other owner of the Company or the Trustee, as such, shall not have any liability for any obligations of the Company under the Securities or for any obligations of the Company or the Trustee under this Indenture or for any claim based on, in respect of or by reason of those obligations or their creation. Each Holder by accepting a Security waives and releases all that liability. The waiver and release shall be part of the consideration for the issue of Securities. SECTION 10.09 Governing Law. THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW 49

YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICTS OF LAWS THEREUNDER TO THE EXTENT THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

The Trustee's certificate of authentication shall be in substantially the following form: "This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. _________________________, as Trustee By: _____________________________________ Authorized Officer". SECTION 2.04 Execution, Authentication, Delivery and Dating. Two Officers of the Company shall sign the Securities of each series on behalf of the Company by manual or facsimile signature. The Company's seal, if any, shall be impressed, affixed, imprinted or reproduced on the Securities and may be in facsimile form. If an Officer of the Company whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless. 11

A Security shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if any Security has been authenticated and delivered hereunder but never issued and sold by the Company, and the Company delivers that Security to the Trustee for cancellation as provided in Section 2.13 together with a written statement (which need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture that Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, and the Trustee shall authenticate and deliver those Securities for original issue on a Company Order for the authentication and delivery of those Securities or pursuant to such procedures reasonably acceptable to the Trustee as may be specified from time to time by Company Order. That order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated, the name or names of the initial Holder or Holders and any other terms of the Securities of that series not otherwise determined. If provided for in those procedures, that Company Order may authorize (1) authentication and delivery of Securities of that series for original issue from time to time, with certain terms (including, without limitation, the Maturity date or dates, original issue date or dates and interest rate or rates) that differ from Security to Security and (2) may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Section 2.01, in authenticating those Securities, and accepting the additional responsibilities under this Indenture in relation to those Securities, the Trustee shall be entitled to receive (in addition to the Company Order referred to above and the other documents required by Section 11.04), and (subject to Section 7.01) shall be fully protected in relying on, (a) an Officers' Certificate setting forth the Board Resolution and, if applicable, an appropriate record of any action taken pursuant thereto, as contemplated by the last paragraph of Section 2.01; and (b) an Opinion of Counsel to the effect that: (i) if the form of those Securities has been established by or pursuant to Board Resolution, as is permitted by Section 2.01, that such form has been established in conformity with the provisions of this Indenture; (ii) if the terms of those Securities have been established by or pursuant to Board Resolution, as is permitted by Section 2.01, that such terms have been established in conformity with the provisions of this Indenture; and 12

(iii) those Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in that Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws in effect from time to time affecting the rights of creditors generally, and the application of general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law). If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers' Certificate and Opinion of Counsel at the time of issuance of each such Security, but that Officers' Certificate and Opinion of Counsel shall be delivered at or before the time of issuance of the first Security of the series to be issued. The Trustee shall not be required to authenticate those Securities if the issuance of those Securities pursuant to this Indenture would affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the Trustee. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. Unless limited by the terms of that appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by that agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company. Each Security shall be dated the date of its authentication. SECTION 2.05 Registrar and Paying Agent. The Company shall maintain an office or agency for each series of Securities where Securities of that series may be presented for registration of transfer or exchange ("Registrar") and an office or agency where Securities of that series may be presented for payment ("Paying Agent"). The Registrar shall keep a register of the Securities of that series and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar, and the term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to that Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. The Company may change any Paying Agent or Registrar without notice to any Holder. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 13

The Company initially appoints the Trustee as Registrar and Paying Agent. SECTION 2.06 Paying Agent to Hold Money in Trust. With respect to each series of Securities, the Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders of Securities of that series or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on or any Additional Amounts with respect to Securities of that series and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent with respect to a series of Securities, it shall segregate and hold in a separate trust fund for the benefit of the Holders of Securities of that series all money held by it as Paying Agent. Each Paying Agent shall otherwise comply with TIA (S) 317(b). SECTION 2.07 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of each series of Securities and shall otherwise comply with TIA (S) 312(a). If the Trustee is not the Registrar with respect to a series of Securities, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date with respect to that series of Securities, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of the Securities of that series, and the Company shall otherwise comply with TIA (S) 312(a). SECTION 2.08 Transfer and Exchange. Except as set forth in Section 2.17 or as may be provided pursuant to Section 2.01, when Securities of any series are presented to the Registrar with the request to register the transfer of those Securities or to exchange those Securities for an equal principal amount of Securities of the same series of like tenor and of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements and the requirements of this Indenture for those transactions are met; provided, however, that the Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instruction of transfer in form reasonably satisfactory to the Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on which instruction the Registrar can rely. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's written request and submission of the Securities (other than Global Securities). No service charge shall be made to a Holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the 14

Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or similar governmental charge payable on exchanges pursuant to Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part pursuant to Article III, except the unredeemed portion of any Security being redeemed in part or (b) any Security during the period beginning 15 Business Days before the mailing of notice of any offer to repurchase Securities of the series required pursuant to the terms thereof or of redemption of Securities of a series to be redeemed and ending at the close of business on the date of mailing. SECTION 2.09 Replacement Securities. If any mutilated Security is surrendered to the Trustee, or if the Holder of a Security claims that the Security has been destroyed, lost or stolen and the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of that Security, the Company shall issue and the Trustee shall authenticate a replacement Security of the same series if the Trustee's requirements are met. If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay that Security. If required by the Trustee or the Company, the Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent or any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security. Every replacement Security is an additional obligation of the Company. SECTION 2.10 Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee hereunder and those described in this Section 2.10 as not outstanding. If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 15

SECTION 2.11 Original Issue Discount, Foreign-Currency Denominated and Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, amendment, supplement, waiver or consent, (a) the principal amount of an Original Issue Discount Security shall be the principal amount thereof that would be due and payable as of the date of that determination upon acceleration of the Maturity thereof pursuant to Section 6.02, (b) the principal amount of a Security denominated in a foreign currency shall be the Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for that currency, as that rate is certified for customs purposes by the Federal Reserve Bank of New York (the "Exchange Rate") on the date of original issuance of that Security, of the principal amount (or, in the case of an Original Issue Discount Security, the Dollar equivalent, as determined by the Company by reference to the Exchange Rate on the date of original issuance of that Security, of the amount determined as provided in (a) above), of that Security and (c) Securities owned by the Company or any other obligor on the Securities or any Affiliate of the Company or of that other obligor shall be disregarded, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, amendment, supplement, waiver or consent, only Securities that the Trustee actually knows are so owned shall be so disregarded. SECTION 2.12 Temporary Securities. Until definitive Securities of any series are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. SECTION 2.13 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or redemption or for credit against any sinking fund payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, redemption, replacement or cancellation or for credit against any sinking fund. Unless the Company shall direct in writing that canceled Securities be returned to it, after written notice to the Company all canceled Securities held by the Trustee shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the Trustee shall maintain a record of their disposal. The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation. 16

SECTION 2.14 Payments; Defaulted Interest. Unless otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, interest (except defaulted interest) on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Persons who are registered Holders of that Security at the close of business on the record date next preceding that Interest Payment Date, even if those Securities are canceled after that record date and on or before that Interest Payment Date. Unless otherwise provided with respect to the Securities of any series, the Company will pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities in Dollars. Those amounts shall be payable at the offices of the Trustee, provided that at the option of the Company, the Company may pay those amounts (1) by wire transfer with respect to Global Securities or (2) by check payable in that money mailed to a Holder's registered address with respect to any Securities. If the Company defaults in a payment of interest on the Securities of any series, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities of that series and in Section 4.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special record date selected by the Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20 days' prior written notice from the Company setting forth that record date and the interest amount to be paid) shall mail to Holders of any such series of Securities a notice that states the special record date, the related payment date and the amount of that interest to be paid. SECTION 2.15 Persons Deemed Owners. The Company, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of that Security for the purpose of receiving payments of principal of, premium (if any) or interest on, or any Additional Amounts with respect to that Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary. SECTION 2.16 Computation of Interest. Except as otherwise specified as contemplated by Section 2.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year comprising twelve 30-day months. SECTION 2.17 Global Securities; Book-Entry Provisions. If Securities of a series are issuable in global form as a Global Security, as contemplated by Section 2.01, then, notwithstanding clause (10) of Section 2.01 and the provisions of Section 2.02, any such Global Security shall represent those of the outstanding Securities of that series as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as 17

appropriate, to reflect exchanges or redemptions. Any endorsement of a Global Security to reflect the amount, or any increase or decrease in the amount, of outstanding Securities represented thereby shall be made by the Trustee (i) in such manner and upon instructions given by such Person or Persons as shall be specified in that Security or in a Company Order to be delivered to the Trustee pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other written form of instructions as is customary for the Depositary for that Security, from that Depositary or its nominee on behalf of any Person having a beneficial interest in that Global Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified in that Security or in the applicable Company Order. With respect to the Securities of any series that are represented by a Global Security, the Company authorizes the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the Depositary appointed with respect to that Global Security. Any Global Security may be deposited with the Depositary or its nominee, or may remain in the custody of the Trustee or the Security Custodian therefor pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee and the Depositary. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel. Members of, or participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee or the Security Custodian as its custodian, or under that Global Security, and the Depositary may be treated by the Company, the Trustee or the Security Custodian and any agent of the Company, the Trustee or the Security Custodian as the absolute owner of that Global Security for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a Global Security of any series may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder of Securities of that series is entitled to take under this Indenture or the Securities of that series and (ii) nothing herein shall prevent the Company, the Trustee or the Security Custodian or any agent of the Company, the Trustee, or the Security Custodian from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Security. Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01, transfers of a Global Security shall be limited to transfers of that Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred in accordance with the rules and procedures of the Depositary. Securities of any series shall be transferred to all beneficial owners of a Global Security of that series in exchange for their beneficial interests in that Global Security if, and only if, either (1) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for that Global Security and a successor Depositary is not appointed by the Company within 90 days of that notice, (2) an Event of Default has occurred with respect to that series and is continuing and the Registrar has received a request from the Depositary to issue Securities of that series in lieu of all or a portion of that Global Security (in which case the Company shall deliver Securities of that series 18

within 30 days of that request) or (3) the Company determines not to have the Securities of that series represented by a Global Security. In connection with any transfer of a portion of the beneficial interests in a Global Security to beneficial owners pursuant to this Section 2.17, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee on receipt of a Company Order for the authentication and delivery of Securities shall authenticate and deliver, one or more Securities of the same series of like tenor and amount. In connection with the transfer of all the beneficial interests in a Global Security of any series to beneficial owners pursuant to this Section 2.17, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate principal amount of Securities of that series of authorized denominations. Neither the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to those Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Global Security Holder or the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from that Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Securities to be issued). The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any Global Security if that Global Security was never issued and sold by the Company and the Company delivers to the Trustee the Global Security together with written instructions (which need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel) with regard to the cancellation or reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of the third paragraph of Section 2.04. Notwithstanding the provisions of Sections 2.03 and 2.14, unless otherwise specified as contemplated by Section 2.01 with respect to Securities of any series, payment of principal of and premium (if any) and interest on and any Additional Amounts with respect to any Global Security shall be made to the Person or Persons specified therein. 19

ARTICLE III REDEMPTION SECTION 3.01 Applicability of Article. Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 2.01 for Securities of any series) in accordance with this Article III. SECTION 3.02 Notice to the Trustee. If the Company elects to redeem Securities of any series pursuant to this Indenture, it shall notify the Trustee of the Redemption Date and principal amount of Securities of that series to be redeemed. The Company shall so notify the Trustee at least 45 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) by delivering to the Trustee an Officers' Certificate stating that the redemption will comply with the provisions of this Indenture and of the Securities of that series. Any such notice may be canceled at any time prior to the mailing of that notice of redemption to any Holder of the Securities of that series and shall thereupon be void and of no effect. SECTION 3.03 Selection of Securities To Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all of the Securities of that series of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Securities of that series (and tenor) not previously called for redemption, either pro rata, by lot or by such other method as the Trustee shall deem fair and appropriate. That redemption may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of that series of a denomination larger than the minimum authorized denomination for Securities of that series or of the principal amount of Global Securities of that series. The Trustee shall promptly notify the Company and the Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities of any series shall relate, in the case of any of the Securities redeemed or to be redeemed only in part, to the portion of the principal amount thereof which has been or is to be redeemed. SECTION 3.04 Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities of a 20

series to be redeemed, at the address of that Holder appearing in the register of Securities for that series maintained by the Registrar. All notices of redemption shall identify the Securities to be redeemed and shall state: (1) the Redemption Date; (2) the Redemption Price; (3) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of those Securities is to receive payment of the Redemption Price on surrender to the Paying Agent of the Securities redeemed; (4) if any Security is to be redeemed in part, the portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, on surrender for cancellation of that Security to the Paying Agent, a new Security or Securities in the aggregate principal amount equal to the unredeemed portion thereof will be issued without charge to the Holder; (5) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and the name and address of the Paying Agent; (6) that the redemption is for a sinking or analogous fund, if that is the case; and (7) the CUSIP number, if any, relating to those Securities. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's written request, by the Trustee in the name and at the expense of the Company. SECTION 3.05 Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent, those Securities called for redemption shall be paid at the Redemption Price, but interest installments whose maturity is on or prior to that Redemption Date will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant record dates specified pursuant to Section 2.01. SECTION 3.06 Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Trustee or the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.06) an amount of money in same day funds sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on 21

and any Additional Amounts with respect to, the Securities or portions thereof which are to be redeemed on that date, other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation. If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of that Redemption Price, interest on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not those Securities are presented for payment, and the Holders of those Securities shall have no further rights with respect to those Securities except for the right to receive the Redemption Price on surrender of those Securities. If any Security called for redemption shall not be so paid on surrender thereof for redemption, the principal of and premium, if any, any Additional Amounts, and, to the extent lawful, accrued interest thereon shall, until paid, bear interest from the Redemption Date at the rate specified pursuant to Section 2.01 or provided in the Securities or, in the case of Original Issue Discount Securities, their initial yield to maturity. SECTION 3.07 Securities Redeemed or Purchased in Part. Upon surrender to the Paying Agent of a Security to be redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of that Security without service charge a new Security or Securities, of the same series and of any authorized denomination as requested by that Holder in aggregate principal amount equal to, and in exchange for, the unredeemed portion of the principal of the Security so surrendered that is not redeemed. SECTION 3.08 Purchase of Securities. Unless otherwise specified as contemplated by Section 2.01, the Company and any Affiliate of the Company may at any time purchase or otherwise acquire Securities in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a redemption of the indebtedness represented by those Securities. Any Securities purchased or acquired by the Company may be delivered to the Trustee for cancellation and, upon that cancellation, the indebtedness represented thereby shall be deemed to be satisfied. Section 2.13 shall apply to all Securities so delivered. SECTION 3.09 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment," and any payment in excess of the minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment." Unless otherwise provided by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.10. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of that series and by this Article III. 22

SECTION 3.10 Satisfaction of Sinking Fund Payments with Securities. The Company may deliver outstanding Securities of a series (other than any previously called for redemption) and may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms of those Securities or through the application of permitted optional sinking fund payments pursuant to the terms of those Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of that series required to be made pursuant to the terms of that series of Securities; provided that those Securities have not been previously so credited. Those Securities shall be received and credited for that purpose by the Trustee at the Redemption Price specified in those Securities for redemption through operation of the sinking fund, and the amount of that sinking fund payment shall be reduced accordingly. SECTION 3.11 Redemption of Securities for Sinking Fund. Not less than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate of the Company specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, that is to be satisfied by payment of cash and the portion thereof, if any, that is to be satisfied by delivery of or by crediting Securities of that series pursuant to Section 3.10 and will also deliver to the Trustee any Securities to be so delivered. Failure of the Company to timely deliver that Officers' Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute the election of the Company (i) that the mandatory sinking fund payment for that series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of that series in respect thereof and (ii) that the Company will make no optional sinking fund payment with respect to that series as provided in this Section. If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $100,000 (or the Dollar equivalent thereof based on the applicable Exchange Rate on the date of original issue of the applicable Securities) or a lesser sum if the Company shall so request with respect to the Securities of any particular series, that cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of that series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If that amount shall be $100,000 (or the Dollar equivalent thereof as aforesaid) or less and the Company makes no such request, then it shall be carried over until a sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is available. Not less than 30 days before each such sinking fund payment date, the Trustee shall select the Securities to be redeemed on that sinking fund payment date in the manner specified in Section 3.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.04. That notice having been duly given, the redemption of those Securities shall be made on the terms and in the manner stated in Sections 3.05, 3.06 and 3.07. 23

ARTICLE IV COVENANTS SECTION 4.01 Payment of Securities. The Company shall pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of each series on the dates and in the manner provided in the Securities of that series and in this Indenture. Principal, premium, interest and any Additional Amounts shall be considered paid on the date due if the Paying Agent, other than the Company or a Subsidiary of the Company, holds on that date money deposited by the Company designated for and sufficient to pay all principal, premium (if any), interest and any Additional Amounts then due. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal of and premium (if any) on Securities of any series, at a rate equal to the then applicable interest rate on the Securities of that series to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest on and any overdue payments of Additional Amounts with respect to Securities of that series (without regard to any applicable grace period) at the same rate to the extent lawful. SECTION 4.02 Maintenance of Office or Agency. The Company will maintain in each Place of Payment for any series of Securities an office or agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities of that series may be presented for registration of transfer or exchange, where Securities of that series may be presented for payment and where notices and demands to or on the Company in respect of the Securities of that series and this Indenture may be served. Unless otherwise designated by the Company by written notice to the Trustee, that office or agency shall be the office of the Trustee in The City of New York, which on the date hereof is located at ____________________. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of that office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, those presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all those purposes and may from time to time rescind those designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for those purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 24

SECTION 4.03 SEC Reports; Financial Statements. (a) The Company shall file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports (or copies of those portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. The Company shall also comply with the provisions of TIA (S) 314(a). (b) If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall furnish to all Holders of Rule 144A Securities and prospective purchasers of Rule 144A Securities designated by the Holders of Rule 144A Securities, promptly on their request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the Securities Act of 1933, as amended. SECTION 4.04 Compliance Certificate. (a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a statement signed by an Officer of the Company, which need not constitute an Officers' Certificate, complying with TIA (S) 314(a)(4) and stating that, in the course of performance by the signing Officer of the Company of his or her duties as such Officer of the Company, he or she would normally obtain knowledge of the keeping, observing, performing and fulfilling by the Company of its obligations under this Indenture, and further stating that, to the best of his or her knowledge, the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which that Officer may have knowledge and what action the Company is taking or proposes to take with respect thereto). (b) The Company shall, so long as Securities of any series are outstanding, deliver to the Trustee, promptly on any Officer of the Company becoming aware of any Default or Event of Default under this Indenture, an Officers' Certificate specifying that Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. SECTION 4.05 Existence. Subject to Article V hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Subsidiaries and all rights (charter and statutory) of the Company and its Subsidiaries, provided that the Company shall not be required to preserve the existence of any Subsidiary of the Company or any such right if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries taken as a whole and that the loss thereof would not have a material adverse effect on the business, operations, assets or financial condition of the Company and its Subsidiaries taken as a whole and would not have any material adverse effect on the payment and performance of the obligations of the Company under the Securities and this Indenture. 25

SECTION 4.06 Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist on, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.07 Additional Amounts. If the Securities of a series expressly provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of that series Additional Amounts as expressly provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received from the sale or exchange of any Security of any series, that mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.07 to the extent that, in that context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 4.07, and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where that express mention is not made. Unless otherwise provided pursuant to Section 2.01 with respect to Securities of any series, if the Securities of a series provide for the payment of Additional Amounts, at least ten days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least ten days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish the Trustee and the Company's principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether that payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then that Officers' Certificate shall specify by country the amount, if any, required to be withheld on those payments to those Holders of Securities, and the Company will pay to that Paying Agent the Additional Amounts required by this Section. The Company covenants to indemnify the Trustee and any Paying Agent for and to hold them harmless against any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers' Certificate furnished pursuant to this Section 4.07. 26

ARTICLE V SUCCESSORS SECTION 5.01 Limitations on Mergers, Consolidations and Other Transactions. The Company shall not, in any transaction or series of related transactions, consolidate with any other Person into, or merge into, any other Person, or sell, lease, convey, transfer or otherwise dispose of its assets substantially as an entirety to any Person, unless: (1) the Person formed by that consolidation or into which the Company is merged, or to which that sale, lease, conveyance, transfer or other disposition shall be made (collectively, the "Successor"), is organized and validly existing under the laws of the United States, any political subdivision thereof or any State thereof or the District of Columbia, and expressly assumes by supplemental indenture the due and punctual payment of the principal of (and premium, if any) and interest on and Additional Amounts with respect to all the Securities and the performance of the Company's covenants and obligations under this Indenture and the Securities; (2) immediately after giving effect to that transaction or series of related transactions, no Default or Event of Default shall have occurred and be continuing; and (3) the Company delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that the transaction and that supplemental indenture comply with this Indenture. SECTION 5.02 Successor Person Substituted. Upon any consolidation or merger of the Company or any sale, lease, conveyance, transfer or other disposition of the assets of the Company substantially as an entirety in accordance with Section 5.01, any Successor formed by that consolidation or into or with which the Company is merged or to which that sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture and the Securities with the same effect as if that Successor had been named as the Company herein and the predecessor Company, in the case of a sale, conveyance, transfer or other disposition, shall be released from all obligations under this Indenture and the Securities. ARTICLE VI DEFAULTS AND REMEDIES SECTION 6.01 Events of Default. Unless either inapplicable to a particular series or specifically deleted or modified in or pursuant to the supplemental indenture or Board Resolution establishing that series of Securities or in the form of Security for that series, an "Event of Default," wherever used herein with respect to Securities of any series, occurs if: 27

(1) the Company defaults in the payment of interest on or any Additional Amounts with respect to any Security of that series when the same becomes due and payable and that default continues for a period of 30 days; (2) the Company defaults in the payment of (A) the principal of any Security of that series at its Maturity or (B) premium (if any) on any Security of that series when the same becomes due and payable; (3) the Company defaults in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series, and that default continues for a period of 30 days; (4) the Company fails to comply with any of its other covenants or agreements in, or provisions of, the Securities of that series or this Indenture (other than an agreement, covenant or provision that has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than that series) which shall not have been remedied within the specified period after written notice, as specified in the last paragraph of this Section 6.01; (5) the Company pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors; (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 90 days and that: (A) is for relief against the Company as debtor in an involuntary case, (B) appoints a Bankruptcy Custodian of the Company or a Bankruptcy Custodian for all or substantially all of the property of the Company, or (C) orders the liquidation of the Company; or (7) any other Event of Default provided with respect to Securities of that series occurs. 28

The term "Bankruptcy Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. The Trustee shall not be deemed to know or have notice of a Default unless a Trust Officer at the Corporate Trust Office of the Trustee receives written notice at the Corporate Trust Office of the Trustee of that Default with specific reference to that Default. When a Default is cured, it ceases. Notwithstanding the foregoing provisions of this Section 6.01, if the principal of, premium (if any) or interest on or Additional Amounts with respect to any Security is payable in a currency or currencies (including a composite currency) other than Dollars and such currency or currencies are not available to the Company for making payment thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company (a "Conversion Event"), the Company will be entitled to satisfy its obligations to Holders of the Securities by making that payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other currency, as determined by the Company by reference to the Exchange Rate on the date of that payment, or, if that rate is not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the foregoing provisions of this Section 6.01, any payment made under such circumstances in Dollars where the required payment is in a currency other than Dollars will not constitute an Event of Default under this Indenture. Promptly after the occurrence of a Conversion Event, the Company shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of that notice, shall give notice thereof in the manner provided in Section 11.02 to the Holders. Promptly after the making of any payment in Dollars as a result of a Conversion Event, the Company shall give notice in the manner provided in Section 11.02 to the Holders, setting forth the applicable Exchange Rate and describing the calculation of those payments. A Default under clause (4) or (7) of this Section 6.01 is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by that Default (or, in the case of a Default under clause (4) of this Section 6.01, if outstanding Securities of other series are affected by that Default, then at least 25% in principal amount of the then outstanding Securities so affected) notify the Company and the Trustee, of the Default, and the Company fails to cure the Default within 90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." SECTION 6.02 Acceleration. If an Event of Default with respect to any Securities of any series at the time outstanding (other than an Event of Default specified in clause (5) or (6) of Section 6.01 hereof) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by that default (or, in the case of an Event of Default described in clause (4) of Section 6.01, if outstanding Securities of other series are affected by that Default, then at least 25% in principal amount of the then outstanding 29

Securities so affected) by notice to the Company and the Trustee, may declare the principal of (or, if any of those Securities are Original Issue Discount Securities, that portion of the principal amount as may be specified in the terms of that series) and all accrued and unpaid interest on all then outstanding Securities of that series or of all series, as the case may be, to be due and payable. Upon any such declaration, the amounts due and payable on those Securities shall be due and payable immediately. If an Event of Default specified in clause (5) or (6) of Section 6.01 hereof occurs, those amounts shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities of the series affected by that default or all series, as the case may be, by written notice to the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of or premium or interest on or any Additional Amounts with respect to the Securities) if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to Securities of that series (or of all series, as the case may be) have been cured or waived, except nonpayment of principal, premium, interest or any Additional Amounts that has become due solely because of the acceleration. SECTION 6.03 Other Remedies. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on the Securities of that series or to enforce the performance of any provision of the Securities of that series or this Indenture. The Trustee may maintain a proceeding with respect to Securities of any series even if it does not possess any of the Securities of that series or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing on an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 6.04 Waiver of Defaults. Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the then outstanding Securities of any series or of all series (acting as one class) by notice to the Trustee may waive an existing or past Default or Event of Default with respect to that series or all series, as the case may be, and its consequences (including waivers obtained in connection with a tender offer or exchange offer for Securities of that series or all series or a solicitation of consents in respect of Securities of that series or all series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of that series or all series (but the terms of that offer or solicitation may vary from series to series)), except (1) a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on or any Additional Amounts with respect to any Security or (2) a continued Default in respect of a provision that under Section 9.02 cannot be amended or supplemented without the consent of each Holder affected. Upon any such waiver, that Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 30

SECTION 6.05 Control by Majority. With respect to Securities of any series, the Holders of a majority in principal amount of the then outstanding Securities of that series may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it relating to or arising under an Event of Default described in clause (1), (2), (3) or (7) of Section 6.01, and with respect to all Securities, the Holders of a majority in principal amount of all the then outstanding Securities affected may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it not relating to or arising under such an Event of Default. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with that direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion from Holders directing the Trustee against all losses and expenses caused by taking or not taking that action. SECTION 6.06 Limitations on Suits. Subject to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy with respect to this Indenture or the Securities of that series only if: (1) the Holder gives to the Trustee written notice of a continuing Event of Default with respect to that series; (2) the Holders of at least 25% in principal amount of the then outstanding Securities of that series make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and (5) during that 60-day period, the Holders of a majority in principal amount of the Securities of that series do not give the Trustee a direction inconsistent with the request. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of and premium, if any, and interest on and any Additional Amounts with respect to that Security, on or after the respective due dates expressed in that Security, 31

or to bring suit for the enforcement of any such payment on or after those respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. SECTION 6.08 Collection Suit by Trustee. If an Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs and is continuing with respect to Securities of any series, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the amount of principal, premium (if any), interest and any Additional Amounts remaining unpaid on the Securities of that series, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, as may be necessary or advisable to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceeding relative to the Company or its creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Bankruptcy Custodian in any such judicial proceeding is hereby authorized by each Holder to make those payments to the Trustee, and in the event that the Trustee shall consent to the making of those payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties which the Holders of the Securities may be entitled to receive in that proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10 Priorities. If the Trustee collects any money pursuant to this Article VI, subject to Article X, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07; 32

Second: to Holders for amounts due and unpaid on the Securities in respect of which or for the benefit of which that money has been collected, for principal, premium (if any), interest and any Additional Amounts ratably, without preference or priority of any kind, according to the amounts due and payable on those Securities for principal, premium (if any), interest and any Additional Amounts, respectively; and Third: to the Company. The Trustee, on prior written notice to the Company, may fix record dates and payment dates for any payment to Holders pursuant to this Article VI. To the fullest extent allowed under applicable law, if for the purpose of obtaining a judgment against the Company in any court it is necessary to convert the sum due in respect of the principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities of any series (the "Required Currency") into a currency in which a judgment will be rendered (the "Judgment Currency"), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Business Day next preceding that on which final judgment is given. Neither the Company nor the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to Holders of Securities under this Section 6.10 caused by a change in exchange rates between the time the amount of a judgment against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required Currency to make payments under this Section to Holders of Securities, but payment of that judgment shall discharge all amounts owed by the Company on the claim or claims underlying that judgment. SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the then outstanding Securities of any series. ARTICLE VII TRUSTEE SECTION 7.01 Duties of Trustee. (a) If an Event of Default with respect to the Securities of any series has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to the Securities of that series, and use the same degree of care and skill in that exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 33

(b) Except during the continuance of an Event of Default with respect to the Securities of any series: (1) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, on certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine those certificates and opinions to determine whether, on their face, they appear to conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: (1) this paragraph does not limit the effect of Section 7.01(b); (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.01. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity reasonably satisfactory to it against any loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. All money received by the Trustee with respect to Securities of any series shall, until applied as herein provided, be held in trust for the payment of the principal of, premium (if any) and interest on and Additional Amounts with respect to the Securities of that series. SECTION 7.02 Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. 34

(b) Before the Trustee acts or refrains from acting, it may require instruction, an Officers' Certificate or an Opinion of Counsel or both to be provided. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on that instruction, Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel, and the written advice of that counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers conferred on it by this Indenture. (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. SECTION 7.03 May Hold Securities. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. However, the Trustee is subject to Sections 7.10 and 7.11. SECTION 7.04 Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities; it shall not be accountable for the Company's use of the proceeds from the Securities or any money paid to the Company or upon the Company's direction under any provision hereof; it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee; and it shall not be responsible for any statement or recital herein or any statement in the Securities other than its certificate of authentication. SECTION 7.05 Notice of Defaults. If a Default or Event of Default with respect to the Securities of any series occurs and is continuing and it is known to the Trustee, the Trustee shall mail to Holders of Securities of that series a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium (if any) and interest on and Additional Amounts or any sinking fund installment with respect to the Securities of that series, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders of Securities of that series. 35

SECTION 7.06 Reports by Trustee to Holders. Within 60 days after each May 15 of each year after the execution of this Indenture, the Trustee shall mail to Holders of a series and the Company a brief report dated as of that reporting date that complies with TIA (S) 313(a); provided, however, that if no event described in TIA (S) 313(a) has occurred within the twelve months preceding the reporting date with respect to a series, no report need be transmitted to Holders of that series. The Trustee also shall comply with TIA (S) 313(b). The Trustee shall also transmit by mail all reports if and as required by TIA (S)(S) 313(c) and 313(d). A copy of each report at the time of its mailing to Holders of a series of Securities shall be filed by the Company with the SEC and each securities exchange, if any, on which the Securities of that series are listed. The Company shall notify the Trustee if and when any series of Securities is listed on any stock exchange. SECTION 7.07 Compensation and Indemnity. The Company agrees to pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company agrees to reimburse the Trustee on request for all reasonable disbursements, advances and expenses incurred by it. Those expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company hereby indemnifies the Trustee against any loss, liability or expense incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, except as set forth in the next paragraph. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel, and the Company shall pay the reasonable fees and expenses of that counsel. The Company need not pay for any settlement made without its consent. The Company shall not be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through negligence or bad faith. To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of any series. That lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(5) or (6) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 36

SECTION 7.08 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only on the successor Trustee's acceptance of appointment as provided in this Section 7.08. The Trustee may resign and be discharged at any time with respect to the Securities of one or more series by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee with respect to the Securities of that series by so notifying the Trustee and the Company. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its property; or (4) the Trustee otherwise becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, with respect to the Securities of one or more series, the Company shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of those series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). Within one year after the successor Trustee with respect to the Securities of any series takes office, the Holders of a majority in principal amount of the Securities of that series may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee with respect to the Securities of any series does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the then outstanding Securities of that series may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of that series. If the Trustee with respect to the Securities of a series fails to comply with Section 7.10, any Holder of Securities of that series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Securities of that series. In case of the appointment of a successor Trustee with respect to all Securities, each such successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become 37

effective, and the successor Trustee shall have all the rights, powers and duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. In case of the appointment of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more (but not all) series shall execute and deliver an indenture supplemental hereto in which each successor Trustee shall accept that appointment and that (1) shall confer to each successor Trustee all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall confirm that all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee. Nothing herein or in that supplemental indenture shall constitute those Trustees co-trustees of the same trust, and each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. Upon the execution and delivery of that supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, and each such successor Trustee shall have all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates. On the request of the Company or any successor Trustee, that retiring Trustee shall transfer to that successor Trustee all property held by that retiring Trustee as Trustee with respect to the Securities of that or those series to which the appointment of that successor Trustee relates. Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 7.08, the obligations of the Company under Section 7.07 shall continue for the benefit of the retiring Trustee or Trustees. SECTION 7.09 Successor Trustee by Merger, etc. Subject to Section 7.10, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee corporation expressly assumes all of the Trustee's liabilities hereunder. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to that authenticating Trustee may adopt that authentication and deliver the Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate those Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all those cases those certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 38

SECTION 7.10 Eligibility; Disqualification. There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under the laws of the United States, any State thereof or the District of Columbia and authorized under those laws to exercise corporate trust power, shall be subject to supervision or examination by Federal or State (or the District of Columbia) authority and shall have, or be a Subsidiary of a bank or bank holding company having, a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. The Indenture shall always have a Trustee who satisfies the requirements of TIA (S)(S) 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA (S) 310(b) during the period of time required by this Indenture. Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA (S) 310(b). SECTION 7.11 Preferential Collection of Claims Against Company. The Trustee is subject to and shall comply with the provisions of TIA (S) 311(a), excluding any creditor relationship listed in TIA (S) 311(b). A Trustee who has resigned or been removed shall be subject to TIA (S) 311(a) to the extent indicated therein. ARTICLE VIII DISCHARGE OF INDENTURE SECTION 8.01 Termination of Company's Obligations. (a) This Indenture shall cease to be of further effect with respect to the Securities of a series (except that the Company's obligations under Section 7.07, the Trustee's and Paying Agent's obligations under Section 8.03 and the rights, powers, protections and privileges accorded the Trustee under Article VII shall survive), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging the satisfaction and discharge of this Indenture with respect to the Securities of that series, when: (1) either (A) all outstanding Securities of that series theretofore authenticated and issued (other than destroyed, lost or stolen Securities that have been replaced or paid) have been delivered to the Trustee for cancellation; or (B) all outstanding Securities of that series not theretofore delivered to the Trustee for cancellation: (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or 39

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and, in the case of clause (i), (ii) or (iii) above, the Company has irrevocably deposited or caused to be deposited with the Trustee as funds (immediately available to the Holders in the case of clause (i)) in trust for that purpose (x) cash in an amount, or (y) Government Obligations, maturing as to principal and interest at such times and in such amounts as will ensure the availability of cash in an amount or (z) a combination thereof, which will be sufficient, in the opinion (in the case of clauses (y) and (z)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge the entire indebtedness on the Securities of that series for principal and any interest and any Additional Amounts to the date of that deposit (in the case of Securities which have become due and payable) or for principal, premium, if any, interest and any Additional Amounts to the Stated Maturity or Redemption Date, as the case may be; or (C) the Company has properly fulfilled such other means of satisfaction and discharge as is specified, as contemplated by Section 2.01, to be applicable to the Securities of that series; (2) the Company has paid or caused to be paid all other sums payable by it hereunder with respect to the Securities of that series; and (3) the Company has delivered to the Trustee an Officers' Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture with respect to the Securities of that series have been complied with, together with an Opinion of Counsel to the same effect. (b) Unless this Section 8.01(b) is specified as not being applicable to Securities of a series as contemplated by Section 2.01, the Company may terminate certain of its obligations under this Indenture ("covenant defeasance") with respect to the Securities of a series if: (1) the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for and dedicated solely to the benefit of the Holders of Securities of that series, (i) money in the currency in which payment of the Securities of that series is to be made in an amount, or (ii) Government Obligations with respect to that series, maturing as to principal and interest at such times and in such amounts as will ensure the availability of money in the currency in which payment of the Securities of that series is to be made in an amount or (iii) a combination thereof, that is sufficient, in the opinion (in the case of clauses (ii) and (iii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay, 40

without consideration of the reinvestment of any such amounts and after payment of all taxes or other charges or assessments in respect thereof payable by the Trustee, the principal of and premium (if any) and interest on and any Additional Amounts with respect to all Securities of that series on each date that such principal, premium (if any), interest or Additional Amounts are due and payable and (at the Stated Maturity thereof or on redemption as provided in Section 8.01(e)) to pay all other sums payable by it hereunder; provided that the Trustee shall have been irrevocably instructed to apply that money and/or the proceeds of those Government Obligations to the payment of said principal, premium (if any), interest and Additional Amounts with respect to the Securities of that series as the same shall become due; (2) the Company has delivered to the Trustee an Officers' Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture with respect to the Securities of that series have been complied with, and an Opinion of Counsel to the same effect; (3) no Default or Event of Default with respect to the Securities of that series shall have occurred and be continuing on the date of that deposit; (4) the Company shall have delivered to the Trustee an Opinion of Counsel from counsel reasonably acceptable to the Trustee or a tax ruling to the effect that the Holders of Securities of that series will not recognize income, gain or loss for Federal income tax purposes as a result of the Company's exercise of its option under this Section 8.01(b) and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if that option had not been exercised; (5) the Company has complied with any additional conditions specified pursuant to Section 2.01 to be applicable to the discharge of Securities of that series pursuant to this Section 8.01; and (6) that deposit and discharge shall not cause the Trustee to have a conflicting interest as defined in TIA (S) 310(b). In that event, this Indenture shall cease to be of further effect (except as set forth in this paragraph), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging satisfaction and discharge under this Indenture. However, the Company's obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 5.01, 7.07, 7.08 and 8.04, the Trustee's and Paying Agent's obligations in Section 8.03 and the rights, powers, protections and privileges accorded the Trustee under Article VII shall survive until all Securities of that series are no longer outstanding. Thereafter, only the Company's obligations in Section 7.07 and the Trustee's and Paying Agent's obligations in Section 8.03 shall survive with respect to Securities of that series. After making the irrevocable deposit pursuant to this Section 8.01(b) and following satisfaction of the other conditions set forth herein, the Trustee on request shall acknowledge in writing the discharge of the Company's obligations under this Indenture with respect to the Securities of that series, except for those surviving obligations specified above. 41

In order to have money available on a payment date to pay principal of or premium (if any) or interest on or any Additional Amounts with respect to the Securities, the Government Obligations shall be payable as to principal or interest on or before that payment date in such amounts as will provide the necessary money. Any such Government Obligations shall not be callable at the issuer's option. (c) If the Company has previously complied or is concurrently complying with Section 8.01(b) (other than any additional conditions specified pursuant to Section 2.01 that are expressly applicable only to covenant defeasance) with respect to Securities of a series, then, unless this Section 8.01(c) is specified as not being applicable to Securities of that series as contemplated by Section 2.01, the Company may elect to be discharged ("legal defeasance") from its obligations to make payments with respect to Securities of that series, if: (1) no Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof shall have occurred at any time during the period ending on the 91st day after the date of deposit contemplated by Section 8.01(b) (it being understood that this condition shall not be deemed satisfied until the expiration of that period); (2) unless otherwise specified with respect to Securities of that series as contemplated by Section 2.01, the Company has delivered to the Trustee an Opinion of Counsel from counsel reasonably acceptable to the Trustee to the effect referred to in Section 8.01(b)(4) with respect to that legal defeasance, which opinion is based on (i) a private ruling of the Internal Revenue Service addressed to the Company, (ii) a published ruling of the Internal Revenue Service or (iii) a change in the applicable federal income tax law (including regulations) after the date of this Indenture; (3) the Company has complied with any other conditions specified pursuant to Section 2.01 to be applicable to the legal defeasance of Securities of that series pursuant to this Section 8.01(c); and (4) the Company has delivered to the Trustee a Company Request requesting legal defeasance of the Securities of that series and an Officers' Certificate stating that all conditions precedent with respect to legal defeasance of the Securities of that series have been complied with, together with an Opinion of Counsel to the same effect. In that event, the Company will be discharged from its obligations under this Indenture and the Securities of that series to pay principal of, premium (if any) and interest on, and any Additional Amounts with respect to, Securities of that series, the Company's obligations under Sections 4.01, 4.02 and 5.01 shall terminate with respect to those Securities, and the entire indebtedness of the Company evidenced by those Securities shall be deemed paid and discharged. (d) If and to the extent additional or alternative means of satisfaction, discharge or defeasance of Securities of a series are specified to be applicable to that series as contemplated by Section 2.01, the Company may terminate any or all of its obligations under this Indenture with respect to Securities of a series and any or all of its obligations under the Securities of that series if 42

it fulfills such other means of satisfaction and discharge as may be so specified, as contemplated by Section 2.01, to be applicable to the Securities of that series. (e) If Securities of any series subject to subsections (a), (b), (c) or (d) of this Section 8.01 are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory or optional sinking fund provisions, the terms of the applicable trust arrangement shall provide for that redemption, and the Company shall make such arrangements as are reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. SECTION 8.02 Application of Trust Money. The Trustee or a trustee reasonably satisfactory to the Trustee and the Company shall hold in trust money or Government Obligations deposited with it pursuant to Section 8.01 hereof. It shall apply the deposited money and the money from Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of the series with respect to which the deposit was made. Money and securities held in trust are not subject to Article X. SECTION 8.03 Repayment to Company. The Trustee and the Paying Agent shall promptly pay to the Company at any time on the written request of the Company any excess money or Government Obligations (or proceeds therefrom) held by them. Subject to the requirements of any applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Company on written request any money held by them for the payment of principal, premium (if any), interest or any Additional Amounts that remain unclaimed for two years after the date on which that payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the Paying Agent with respect to that money shall cease. SECTION 8.04 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or Government Obligations deposited with respect to Securities of any series in accordance with Section 8.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting that application, the obligations of the Company under this Indenture with respect to the Securities of that series and under the Securities of that series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money or Government Obligations in accordance with Section 8.01; provided, however, that if the Company has made any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Securities because of the reinstatement of its obligations, the Company shall be 43

subrogated to the rights of the Holders of those Securities to receive such payment from the money or Government Obligations held by the Trustee or the Paying Agent. ARTICLE XI SUPPLEMENTAL INDENTURES AND AMENDMENTS SECTION 9.01 Without Consent of Holders. The Company and the Trustee may amend or supplement this Indenture or the Securities or waive any provision hereof or thereof without the consent of any Holder: (1) to cure any ambiguity, omission, defect or inconsistency; (2) to comply with Section 5.01; (3) to provide for uncertificated Securities in addition to or in place of certificated Securities, or to provide for the issuance of bearer Securities (with or without coupons); (4) to provide any security for any series of Securities or to add guarantees of any series of Securities; (5) to comply with any requirement in order to effect or maintain the qualification of this Indenture under the TIA; (6) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if those covenants are to be for the benefit of less than all series of Securities, stating that those covenants are expressly being included solely for the benefit of that series), or to surrender any right or power herein conferred on the Company; (7) to add any additional Events of Default with respect to all or any series of the Securities (and, if any such Event of Default is applicable to less than all series of Securities, specifying the series to which that Event of Default is applicable); (8) to change or eliminate any of the provisions of this Indenture; provided that any such change or elimination shall become effective only when there is no outstanding Security of any series created prior to the execution of that amendment or supplemental indenture that is adversely affected in any material respect by that change in or elimination of that provision; (9) to establish the form or terms of Securities of any series as permitted by Section 2.01; (10) to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Section 8.01; provided, however, that any such action shall not adversely affect 44

the interest of the Holders of Securities of that series or any other series of Securities in any material respect; or (11) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 7.08. Upon the request of the Company, accompanied by a Board Resolution, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained. SECTION 9.02 With Consent of Holders. Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture with the written consent (including consents obtained in connection with a tender offer or exchange offer for Securities of any one or more series or all series or a solicitation of consents in respect of Securities of any one or more series or all series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of each such series (but the terms of that offer or solicitation may vary from series to series)) of the Holders of at least a majority in principal amount of the then outstanding Securities of all series affected by that amendment or supplement (acting as one class). Upon the request of the Company, accompanied by a Board Resolution, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company in the execution of that amendment or supplemental indenture. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if that consent approves the substance thereof. The Holders of a majority in principal amount of the then outstanding Securities of one or more series or of all series may waive compliance in a particular instance by the Company with any provision of this Indenture with respect to Securities of that series (including waivers obtained in connection with a tender offer or exchange offer for Securities of that series or a solicitation of consents in respect of Securities of that series, provided that in each case that offer or solicitation is made to all Holders of then outstanding Securities of that series (but the terms of that offer or solicitation may vary from series to series)). However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not: 45

(1) reduce the amount of Securities whose Holders must consent to an amendment, supplement or waiver; (2) reduce the rate of or change the time for payment of interest, including default interest, on any Security; (3) reduce the principal of, premium on or any mandatory sinking fund payment with respect to, or change the Stated Maturity of, any Security or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable on a declaration of acceleration of the Maturity thereof pursuant to Section 6.02; (4) reduce the premium, if any, payable on the redemption of any Security or change the time at which any Security may or shall be redeemed; (5) change any obligation of the Company to pay Additional Amounts with respect to any Security; (6) change the coin or currency or currencies (including composite currencies) in which any Security or any premium, interest or Additional Amounts with respect thereto are payable; (7) impair the right to institute suit for the enforcement of any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Security pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06; (8) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of this Indenture pursuant to Section 6.04 or 6.07 or make any change in this sentence of Section 9.02; (9) modify the provisions of this Indenture with respect to the subordination of any Security in a manner adverse to the Holder thereof; or (10) waive a continuing Default or Event of Default in the payment of principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities. An amendment under this Section may not make any change that adversely affects the rights under Article X of any holder of an issue of Senior Indebtedness of the Company unless the holders of the issue pursuant to its terms consent to the change. A supplemental indenture that changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of that series with respect to that covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 46

The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from that Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which that consent is required or sought as of a date identified by the Company in a notice furnished to Holders in accordance with the terms of this Indenture. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail that notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. SECTION 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect. SECTION 9.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his or her Security or portion of a Security if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. The Company may, but shall not be obligated to, fix a record date (which need not comply with Section 316(c) of the TIA) for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at that record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to that amendment, supplement or waiver or to revoke any consent previously given, whether or not those Persons continue to be Holders after that record date. No consent shall be valid or effective for more than 90 days after that record date unless consents from Holders of the principal amount of Securities required hereunder for that amendment or waiver to be effective shall have also been given and not revoked within that 90-day period. After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (9) of Section 9.02 hereof. In that case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder's Security. 47

SECTION 9.05 Notation on or Exchange of Securities. If an amendment or supplement changes the terms of an outstanding Security, the Company may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security at the request of the Company regarding the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of that amendment or supplement. Securities of any series authenticated and delivered after the execution of any amendment or supplement may, and shall if required by the Company, bear a notation in form approved by the Company as to any matter provided for in that amendment or supplement. SECTION 9.06 Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or supplement authorized pursuant to this Article if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign that amendment or supplement, the Trustee shall be entitled to receive, and, subject to Section 7.01 hereof, shall be fully protected in relying on, an Opinion of Counsel provided at the expense of the Company as conclusive evidence that such amendment or supplement is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding on the Company in accordance with its terms. ARTICLE X SUBORDINATION SECTION 10.01 Securities Subordinated to Senior Indebtedness. The Company and each Holder of a Security, by his or her acceptance thereof, agree that (a) the payment of the principal of, premium (if any) and interest on and any Additional Amounts with respect to each and all the Securities and (b) any other payment in respect of the Securities, including on account of the acquisition or redemption of Securities by the Company, is subordinated, to the extent and in the manner provided in this Article X, to the prior payment in full of all Senior Indebtedness of the Company, whether outstanding at the date of this Indenture or thereafter created, incurred, assumed or guaranteed, and that these subordination provisions are for the benefit of the holders of Senior Indebtedness of the Company. Each Holder of a Security, by his or her acceptance thereof, acknowledges and agrees that the provisions of this Article X are, and are intended to be, an inducement and a consideration to all Persons who, in reliance on such provisions, become holders of, or continue to hold, Senior Indebtedness of the Company, and such provisions are made for the benefit of the holders of Senior Indebtedness of the Company, and those holders are made obligees hereunder, and any one or more of them may enforce such provisions. 48

SECTION 10.02 No Payment on Securities in Certain Circumstances . (a) Unless otherwise specified with respect to Securities of a series as contemplated by Section 2.01, no payment shall be made by or on behalf of the Company on account of the principal of, premium (if any) or interest on or any Additional Amounts with respect to the Securities of any series or to acquire any of those Securities (including any repurchases of those Securities pursuant to the provisions thereof at the option of the Holder of those Securities) for cash or property (other than Junior securities of the Company), or on account of any redemption provisions of those Securities, in the event of default in payment of any principal of, premium (if any) or interest on any Senior Indebtedness of the Company when the same becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration of acceleration or otherwise (a "Payment Default"), unless and until that Payment Default has been cured or waived or otherwise has ceased to exist. (b) Unless otherwise specified with respect to Securities of a series as contemplated by Section 2.01, no payment shall be made by or on behalf of the Company on account of the principal of, premium (if any) or interest on or any Additional Amounts with respect to the Securities of any series or to acquire any of those Securities (including any repurchases of those Securities pursuant to the provisions thereof at the option of the Holder of those Securities) for cash or property (other than Junior securities of the Company), or on account of the redemption provisions of those Securities, in the event of any event of default (other than a Payment Default) with respect to any Designated Senior Indebtedness permitting the holders of that Designated Senior Indebtedness (or a trustee or other representative on behalf of the holders thereof) to declare that Designated Senior Indebtedness due and payable prior to the date on which it would otherwise have become due and payable, on written notice thereof to the Company and the Trustee by any holders of Designated Senior Indebtedness (or a trustee or other representative on behalf of the holders thereof) (the "Payment Blocking Notice"), unless and until that event of default shall have been cured or waived or otherwise has ceased to exist; provided, that such payments may not be prevented pursuant to this Section 10.02(b) for more than 179 days after an applicable Payment Blocking Notice has been received by the Trustee unless the Designated Senior Indebtedness in respect of which that event of default exists has been declared due and payable in its entirety, in which case no such payment may be made until that acceleration has been rescinded or annulled or that Designated Senior Indebtedness has been paid in full. Unless otherwise specified with respect to Securities of a series as contemplated by Section 2.01, no event of default that existed or was continuing on the date of any Payment Blocking Notice (whether or not that event of default is on the same issue of Designated Senior Indebtedness) may be made the basis for the giving of a second Payment Blocking Notice, and only one such Payment Blocking Notice may be given in any period of 365 consecutive days. (c) In furtherance of the provisions of Section 10.01, in the event that, notwithstanding the foregoing provisions of this Section 10.02, any payment or distribution of assets of the Company (other than Junior securities of the Company) shall be received by the Trustee or the Holders of the Securities of any series or any Paying Agent with respect thereto at a time when that payment or distribution was prohibited by the provisions of this Section 10.02, then, unless that payment or distribution is no longer prohibited by this Section 10.02, that payment or distribution (subject to the provisions of Section 10.07) shall be received and held in trust by the Trustee or such 49

Holders or Paying Agent for the benefit of the holders of Senior Indebtedness of the Company, and shall be paid or delivered by the Trustee or such Holders or Paying Agent, as the case may be, to the holders of Senior Indebtedness of the Company remaining unpaid or unprovided for or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing that Senior Indebtedness of the Company may have been issued, ratably, according to the aggregate amounts remaining unpaid on account of that Senior Indebtedness of the Company held or represented by each, for application to the payment of all Senior Indebtedness of the Company in full after giving effect to all concurrent payments and distributions to or for the holders of that Senior Indebtedness. SECTION 10.03 Securities Subordinated to Prior Payment of All Senior Indebtedness on Dissolution, Liquidation or Reorganization. Upon any distribution of assets of the Company or upon any dissolution, winding up, total or partial liquidation or reorganization of the Company, whether voluntary or involuntary, in bankruptcy, insolvency, receivership or similar proceeding or upon assignment for the benefit of creditors: (a) the holders of all Senior Indebtedness of the Company shall first be entitled to receive payments in full before the Holders of Securities of any series are entitled to receive any payment (other than in the form of Junior securities of the Company) on account of the principal of, premium (if any) or interest on or any Additional Amounts with respect to those Securities; (b) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (other than Junior securities of the Company), to which the Holders of Securities of any series or the Trustee on behalf of those Holders would be entitled, except for the provisions of this Article X, shall be paid by the liquidating trustee or agent or other Person making such a payment or distribution directly to the holders of that Senior Indebtedness or their representative, ratably according to the respective amounts of Senior Indebtedness held or represented by each, to the extent necessary to make payment in full of all that Senior Indebtedness remaining unpaid after giving effect to all concurrent payments and distributions to the holders of that Senior Indebtedness; and (c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (other than Junior securities of the Company), shall be received by the Trustee or the Holders of Securities of any series or any Paying Agent with respect thereto (or, if the Company or any Affiliate of the Company is acting as its own Paying Agent, money for any such payment or distribution shall be segregated or held in trust) on account of the principal of, premium (if any) or interest on or any Additional Amounts with respect to the Securities of that series before all Senior Indebtedness of the Company is paid in full, that payment or distribution (subject to the provisions of Section 10.07) shall be received and held in trust by the Trustee or such Holder or Paying Agent for the benefit of the holders of that Senior Indebtedness, or their respective representatives, ratably according to the respective amounts of that Senior Indebtedness held or represented by each, to the extent necessary to make payment as 50

provided herein of all that Senior Indebtedness remaining unpaid after giving effect to all concurrent payments and distributions and all provisions therefor to or for the holders of that Senior Indebtedness, but only to the extent that as to any holder of that Senior Indebtedness, as promptly as practical following notice from the Trustee to the holders of that Senior Indebtedness that such prohibited payment has been received by the Trustee, Holder(s) or Paying Agent (or has been segregated as provided above), that holder (or a representative therefor) notifies the Trustee of the amounts then due and owing on that Senior Indebtedness, if any, held by that holder, and only the amounts specified in those notices to the Trustee shall be paid to the holders of that Senior Indebtedness. SECTION 10.04 Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness of the Company as provided herein, the Holders of the Securities shall be subrogated (to the extent of the payments or distributions made to the holders of that Senior Indebtedness pursuant to the provisions of this Article X) to the rights of the holders of that Senior Indebtedness to receive payments or distributions of assets of the Company applicable to that Senior Indebtedness until all amounts owing on the Securities shall be paid in full. For the purpose of that subrogation, no such payments or distributions to the holders of that Senior Indebtedness by the Company, or by or on behalf of the Holders of the Securities by virtue of this Article X, which otherwise would have been made to those Holders shall, as among the Company, its creditors other than the holders of Senior Indebtedness of the Company and those Holders, be deemed to be payment by the Company or on account of that Senior Indebtedness, it being understood that the provisions of this Article X are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand,and the holders of that Senior Indebtedness, on the other hand. If any payment or distribution to which the Holders of the Securities would otherwise have been entitled but for the provisions of this Article X shall have been applied, pursuant to the provisions of this Article X, to the payment of amounts payable under Senior Indebtedness of the Company, then those Holders shall be entitled to receive from the holders of that Senior Indebtedness any payments or distributions received by those holders of Senior Indebtedness of the Company in excess of the amount sufficient to pay all amounts payable under or in respect of that Senior Indebtedness in full. SECTION 10.05 Obligations of the Company Unconditional. Nothing contained in this Article X or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Company and the Holders of the Securities of any series, the obligation of the Company, which is absolute and unconditional, to pay to those Holders the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of that series as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of those Holders and creditors of the Company other than the holders of Senior Indebtedness of the Company, nor shall anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law on default under this Indenture, subject to the rights, if any, under this Article X, of the holders of Senior Indebtedness of the Company in respect of cash, property or securities of the 51

Company received on the exercise of any such remedy. Notwithstanding anything to the contrary in this Article X or elsewhere in this Indenture or in the Securities, on any distribution of assets of the Company referred to in this Article X, the Trustee, subject to the provisions of Sections 7.01 and 7.02, and the Holders of the Securities shall be entitled to rely on any order or decree made by any court of competent jurisdiction in which such dissolution, winding up, liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee or agent or other Person making any distribution to the Trustee or to those Holders for the purpose of ascertaining the Persons entitled to participate in that distribution, the holders of Senior Indebtedness of the Company and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article X so long as that court has been apprised of the provisions of, or the order, decree or certificate makes reference to, the provisions of this Article X. SECTION 10.06 Trustee Entitled to Assume Payments Not Prohibited in Absence of Notice. The Trustee shall not at any time be charged with knowledge of the existence of any facts that would prohibit the making of any payment to or by the Trustee unless and until a Responsible Officer of the Trustee or any Paying Agent shall have received, no later than two Business Days prior to that payment, written notice thereof from the Company or from one or more holders of Senior Indebtedness of the Company or from any representative therefor and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Sections 7.01 and 7.02, shall be entitled in all respects conclusively to assume that no such fact exists. SECTION 10.07 Application by Trustee of Amounts Deposited with It . Amounts deposited in trust with the Trustee pursuant to and in accordance with Article VIII shall be for the sole benefit of Holders of the Securities of the series for the benefit of which those amounts were deposited, and, to the extent allocated for the payment of Securities of that series, shall not be subject to the subordination provisions of this Article X. Otherwise, any deposit of assets with the Trustee or the Paying Agent (whether or not in trust) for the payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Securities shall be subject to the provisions of Sections 10.01, 10.02, 10.03 and 10.04; provided that if prior to two Business Days preceding the date on which by the terms of this Indenture any such assets may become distributable for any purpose (including, without limitation, the payment of either principal of, premium (if any) or interest on or any Additional Amounts with respect to any Security), the Trustee or such Paying Agent shall not have received with respect to those assets the written notice provided for in Section 10.06, then the Trustee or such Paying Agent shall have full power and authority to receive those assets and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary that may be received by it on or after that date; and provided further that nothing contained in this Article X shall prevent the Company from making, or the Trustee from receiving or applying, any payment in connection with the redemption of Securities if the first publication of notice of that redemption (whether by mail or otherwise in accordance with this Indenture) has been made, and the Trustee has received that payment from the Company, prior to the occurrence of any of the contingencies specified in Section 10.02 or 10.03. 52

SECTION 10.08 Subordination Rights Not Impaired by Acts or Omissions of the Company or Holders of Senior Indebtedness. No right of any present or future holders of any Senior Indebtedness of the Company to enforce the subordination provisions contained in this Article X shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms of this Indenture, regardless of any knowledge thereof that any such holder may have or be otherwise charged with. The holders of Senior Indebtedness of the Company may extend, renew, modify or amend the terms of the Senior Indebtedness or any security therefor and release, sell or exchange that security and otherwise deal freely with the Company, all without affecting the liabilities and obligations of the parties to this Indenture or the Holders of the Securities. SECTION 10.09 Trustee to Effectuate Subordination of Securities. Each Holder of a Security by his acceptance thereof authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provisions contained in this Article X and to protect the rights of the Holders of the Securities pursuant to this Indenture, and appoints the Trustee his attorney-in-fact for that purpose, including, in the event of any dissolution, winding up, liquidation or reorganization of the Company (whether in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors of the Company), the filing of a claim for the unpaid balance of his Securities in the form required in said proceedings and cause said claim to be approved. If the Trustee does not file a proper claim or proof of debt in the form required in that proceeding prior to 30 days before the expiration of the time to file such claim or claims, then the holders of Senior Indebtedness of the Company or their representative is hereby authorized to have the right to file and is hereby authorized to file an appropriate claim for and on behalf of the Holders of said Securities. Nothing herein contained shall be deemed to authorize the Trustee or the holders of Senior Indebtedness of the Company or their representative to authorize or consent to or accept or adopt on behalf of any Holder of Securities any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee or the holders of Senior Indebtedness of the Company or their representative to vote in respect of the claim of any Holder of the Securities in any such proceeding. SECTION 10.10 Right of Trustee to Hold Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all of the rights set forth in this Article X in respect of any Senior Indebtedness of the Company at any time held by it to the same extent as any other holder of Senior Indebtedness of the Company, and nothing in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder. SECTION 10.11 Article X Not to Prevent Events of Default. The failure to make a payment on account of principal of or premium (if any) or interest on or any Additional Amounts with respect to the Securities by reason of any provision of this Article X shall not be construed as preventing the occurrence of a Default or an Event of Default 53

under Section 6.01 or in any way prevent the Holders of the Securities from exercising any right hereunder other than the right to receive payment on the Securities. SECTION 10.12 No Fiduciary Duty of Trustee to Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company, and shall not be liable to any of those holders (other than for its willful misconduct or gross negligence) if it shall in good faith mistakenly pay over or distribute to the Holders of the Securities or the Company or any other Person, cash, property or securities to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article X or otherwise. Nothing in this Section 10.12 shall affect the obligation of any other such Person to hold that payment for the benefit of, and to pay that payment over to, the holders of Senior Indebtedness of the Company or their representative. SECTION 10.13 Article Applicable to Paying Agent. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article X shall in that case (unless the context shall otherwise require) be construed as extending to and including that Paying Agent within its meaning as fully for all intents and purposes as if that Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that this Section 10.13 shall not apply to the Company or any Affiliate of the Company if it or that Affiliate acts as Paying Agent. ARTICLE XI MISCELLANEOUS SECTION 11.01 Trust Indenture Act Controls.
