Dear Sirs:

USA Waste Services, Inc., a Delaware corporation (the "Company"), proposes to issue and sell $300,000,000 principal amount of its 7% Senior Notes due 2004 (the "Securities"), to the several underwriters named in Schedule I hereto (the "Underwriters"). The Securities are to be issued pursuant to the provisions of an indenture (the "Senior Indenture") to be dated as of September 10, 1997 between the Company and Texas Commerce Bank, National Association, as trustee (the "Trustee"). The terms of the Securities are set forth in resolutions of the Pricing Committee of the Board of Directors of the Company dated as of the date hereof (the "Resolutions").

1. Registration Statement and Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the "Commission") in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively called the "Act"), a registration statement on Form S-3 (Registration No. 333-32471), including a prospectus relating to the Securities, which may be amended. The registration statement as amended at the time when it became effective, including all documents or information incorporated or deemed to be incorporated by reference therein is referred to as the "Registration Statement"; and the prospectus in the form first used to confirm sales of Securities, (including (a) the information contained in any prospectus supplement relating to the Securities or deemed to be part of the Registration Statement at effectiveness pursuant to Rule 430A or Rule 434 of the Act, and (b) any documents or information incorporated or deemed to be incorporated by reference into such prospectus), are hereinafter referred to as the "Prospectus". Any registration statement (including any amendment or supplement thereto or information which is deemed to be a part thereof) filed by the Company under Rule 462(b) of the Act (a "Rule 462(b) Registration Statement") shall be deemed to be a part of the Registration Statement. If the


Company elects to rely on Rule 434 under the Act, all references to the Prospectus shall be deemed to also include, without limitation, the form of prospectus and term sheet (a "Term Sheet"), taken together, provided to the Underwriters by the Company in reliance on Rule 434 under the Act (the "Rule 434 Prospectus"). All references in this Agreement to financial statements and schedules and other information which is "contained," "included," "described" or "stated" in the Registration Statement or the Prospectus (and all references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or the Prospectus shall be deemed to mean and include, without limitation, even through not specifically stated, any document filed under the Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the "Exchange Act") which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus after the effective date, as the case may be.

2. Agreements to Sell and Purchase. On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to issue and sell, and each Underwriter agrees, severally and not jointly, to purchase from the Company the principal amount of Securities set forth opposite the name of such Underwriter in Schedule I hereto at 99.172% of the principal amount thereof (the "Purchase Price") plus accrued interest thereon, if any, from September 15, 1997 to the date of payment and delivery.

3. Terms of Public Offering.

(j) The Senior Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, enforceable in accordance with its terms except as (i) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors' rights generally and (ii) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability.

(k) The Securities conform as to legal matters to the description thereof contained in the Prospectus.

(l) The capitalization of the Company conforms as to legal matters to the description thereof included in the Prospectus.

(m) Neither the Company nor any of its subsidiaries is in violation of its respective charter or by-laws or in default in the performance of any obligation, agreement or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any other agreement, indenture or instrument material to the conduct of the business of the Company and its subsidiaries, taken as a whole, to which the Company or any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective properties are bound.

(n) The execution, delivery and performance of this Agreement, the Senior Indenture and the Securities and compliance by the Company with all the provisions hereof and thereof and the consummation of the transactions contemplated hereby and thereby will not require any consent, approval, authorization or order of any court, regulatory body, administrative agency or other governmental body (except such as may be required under the securities or Blue Sky laws of the various states or jurisdictions outside the United States) and will not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws of the Company or any of its subsidiaries or any agreement, indenture or other instrument to which it or any of its subsidiaries is a party or by which it or any of its subsidiaries or their respective properties are bound, or violate or conflict with any laws, administrative regulations or rulings or court decrees applicable to the Company, any of its subsidiaries or their respective properties.

(o) Except as otherwise set forth in the Prospectus, there are no material legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any of their respective properties are the subject, and, to the Company's knowledge, no such proceedings are threatened or contemplated. No material development has occurred with respect to the legal proceedings described in the Registration Statement. No contract or document of a character required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement is not so described or filed as required.

(p) Neither the Company nor any of its subsidiaries has violated any foreign, federal, state or local law or regulation relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants

-7-

("Environmental Laws"), nor any federal or state law relating to discrimination in the hiring, promotion or pay of employees nor any applicable federal or state wages and hours laws, nor any provisions of the Employee Retirement Income Security Act or the rules and regulations promulgated thereunder, which in each case might result in any material adverse change in the business, prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole.

(q) The Company and each of its subsidiaries has such permits, licenses, franchises and authorizations of governmental or regulatory authorities ("permits"), including, without limitation, under any applicable Environmental Laws, as are necessary to own, lease and operate its respective properties and to conduct its business as currently being conducted and as the Company expects it to be conducted except where the failure to have such permits would not have a material adverse effect on the Company and its subsidiaries, taken as a whole; the Company and each of its subsidiaries has fulfilled and performed all of its material obligations with respect to such permits and no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the holder of any such permit; and, except as described in the Prospectus, such permits contain no restrictions that are materially burdensome to the Company or any of its subsidiaries.

(r) In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, except to the extent properly accrued for in the Company's financial statements, singly or in the aggregate, have a material adverse effect on the Company and its subsidiaries, taken as a whole.

(s) Except as otherwise set forth in the Prospectus or such as are not material to the business, prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, the Company and each of its subsidiaries has good and marketable title, free and clear of all liens, claims, encumbrances and restrictions, except liens for taxes not yet due and payable, to all property and assets described in the Registration Statement as being owned by it. All leases to which the Company or any of its subsidiaries is a party are valid and binding and no default has occurred or is continuing thereunder that might result in any material adverse change in the business, prospects, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, and the Company and its subsidiaries enjoy peaceful and undisturbed possession under all such leases to which any of them is a party as lessee with such exceptions as do not materially interfere with the use made by the Company or such subsidiary.

(t) The Company and each of its subsidiaries maintains insurance as is customary in the industry.

-8-

No other financial statements or schedules are required by the Act or the Exchange Act to be included in the Registration Statement or the Prospectus.

(w) The Company is not an "investment company" or a company "controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended.

(x) No holder of any security of the Company has any right to require registration of shares of Common Stock or any other security of the Company because of the filing of the Registration Statement, which has not been waived.

(y) There are no outstanding subscriptions, rights, warrants, options, calls, convertible securities, commitments of sale or liens related to or entitling any person to purchase or otherwise to acquire any shares of the capital stock of, or other ownership interest in, the Company or any subsidiary thereof except as otherwise disclosed in the Registration Statement or Prospectus.

(bb) The Company and each of its subsidiaries maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management's general or specific authorizations; (ii) transactions are recorded as necessary

-9-

to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management's general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(cc) All material tax returns required to be filed by the Company and each of its subsidiaries in any jurisdiction have been filed, other than those filings being contested in good faith, and all material taxes, including withholding taxes, penalties and interest, assessments, fees and other charges due pursuant to such returns or pursuant to any assessment received by the Company or any of its subsidiaries have been paid, other than those being contested in good faith and for which adequate reserves have been provided.

(dd) Subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus and prior to the Closing Date, (i) there has not been and will not have been, except as set forth in or as contemplated by the Registration Statement and the Prospectus any change in the capitalization, long term or short term debt or in the capital stock or equity of the Company or any of its subsidiaries, (ii) neither the Company nor any of its subsidiaries has incurred any material liabilities or obligations, direct or contingent, nor has it entered into any material transactions other than pursuant to this Agreement, and the transactions referred to herein, or as contemplated in the Prospectus, and (iii) there has not been any material adverse effect, or any development involving a prospective material adverse effect, in or affecting the general affairs, management, financial position, shareholders' equity (or, with respect to partnership subsidiaries, partnership capital), net worth or results of operations of the Company and its subsidiaries, taken as a whole.

(ee) The Company and its affiliates have not taken, and will not take, directly or indirectly, any action designed to, or which might reasonably be expected to, cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities pursuant to the distribution contemplated by this Agreement, and other than as permitted by the Act, the Company has not distributed and will not distribute any prospectus or other offering material in connection with the offering and sale of the Securities.

Any certificate or other document signed by any officer or authorized representative of the Company and delivered to the Underwriters or to counsel for the Underwriters shall be deemed a representation and warranty of the Company to each Underwriter as to the matter covered thereby.

7. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or

-10-

omission or alleged untrue statement or omission based upon information relating to any Underwriters furnished in writing to the Company by or on behalf of any Underwriter through you expressly for use therein.

(b) The indemnity agreement contained in paragraph 7(a), with respect to any preliminary prospectus, shall not inure to the benefit of any Underwriter to the extent that any loss, claim, damage or liability results from the fact that a copy of the Prospectus was not sent or given by or on behalf of such Underwriter to the person asserting any such loss, claim, damage or liability to the extent that the Prospectus would have cured the defect giving rise to such loss, claim, damage, liability or judgment if such Underwriter shall have been provided with the number of copies of the Prospectus requested by such Underwriter and it is judicially determined that such delivery was required under the Securities Act and was not so made.

(c) In case any action shall be brought against any Underwriter or any person controlling such Underwriter, based upon any preliminary prospectus, the Registration Statement or the Prospectus or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such Underwriter shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses. Any Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the employment of such counsel has been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel, or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the Company and such Underwriter or such controlling person shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Underwriters and controlling persons, which firm shall be designated in writing by Donaldson, Lufkin & Jenrette Securities Corporation and that all such fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent, but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any Underwriter and any such controlling person from and against any loss or liability by reason of such settlement. Notwithstanding the immediately preceding sentence, if in any case where the fees and expenses of counsel are at the expense of the Company and an indemnified party shall have requested the Company to reimburse the indemnified party for such fees and expenses of counsel as incurred, the Company agrees that it shall be liable for any settlement of any action effected without its written consent if (i) such settlement is entered into more than forty business days after the receipt by the Company of the aforesaid request and (ii) the Company shall have failed to reimburse the indemnified party in accordance with such request for reimbursement prior to the date of such settlement. The Company shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity

-11-

could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, and any person controlling the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only with reference to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus or any preliminary prospectus. In case any action shall be brought against the Company, any of its directors, any such officer or any person controlling the Company based on the Registration Statement, the Prospectus or any preliminary prospectus and in respect of which indemnity may be sought against any Underwriter, the Underwriter shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), and the Company, its directors, any such officers and any person controlling the Company shall have the rights and duties given to the Underwriter, by Section 7(c) hereof.

(e) If the indemnification provided for in this Section 7 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, bear to the total price to the public of the Securities, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding

-12-

paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 7(e) are several in proportion to the respective number of Securities purchased by each of the Underwriters hereunder and not joint.

(f) The Company hereby designates CT Corporation Systems, Inc., 1633 Broadway, New York, New York 10019, (a Delaware corporation) as its authorized agent, upon which process may be served in any action, suit or proceeding which may be instituted in any state or federal court in the State of New York by any Underwriter or person controlling an Underwriter asserting a claim for indemnification or contribution under or pursuant to this Section 7, and the Company will accept the jurisdiction of such court in such action, and waives, to the fullest extent permitted by applicable law, any defense based upon lack of personal jurisdiction or venue. A copy of any such process shall be sent or given to the Company, at the address for notices specified in Section 10 hereof.

8. Conditions of Underwriters' Obligations. The several obligations of the Underwriters under this Agreement are subject to the satisfaction of each of the following conditions:

(j) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating or outlook accorded any of the Company's securities by any "nationally recognized statistical rating organization," as such term is defined for purposes of Rule 436(g)(2) under the Act.

9. Effective Date of Agreement and Termination. This Agreement shall become effective upon the later of (i) execution of this Agreement and
(ii) when notification of the effectiveness of the Registration Statement has been released by the Commission.

This Agreement may be terminated at any time prior to the Closing Date by you by written notice to the Company if any of the following has occurred:
(i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any adverse change or development involving a prospective adverse change in the condition, financial or otherwise, of the Company or any of its subsidiaries or the earnings, affairs, or business prospects of the Company or any of its subsidiaries, whether or not arising in the ordinary course of business, which would, in your judgment, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (ii) any outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic conditions or in the financial markets of the United States or elsewhere that, in your judgment, is material and adverse and would, in your judgment, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (iii) the suspension or material limitation of trading in securities on the New York Stock Exchange, the American Stock Exchange or the NASDAQ National Market System or limitation on prices for securities on any such exchange or National Market System, (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects, or will materially and adversely affect, the business or operations of the Company or any

-18-

Subsidiary, (v) the declaration of a banking moratorium by either federal or New York State authorities or (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in your opinion has a material adverse effect on the financial markets in the United States.

If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase the Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase is not more than one-tenth of the total principal amount of the Securities to be purchased on such date by all Underwriters, each non-defaulting Underwriter shall be obligated severally, in the proportion which the principal amount of Securities set forth opposite its name in Schedule I bears to the total principal amount of Securities which all the non- defaulting Underwriters, as the case may be, have agreed to purchase, or in such other proportion as you may specify, to purchase the Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities which any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Securities, without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date by all Underwriters and arrangements satisfactory to you and the Company for purchase of such Securities are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter and the Company. In any such case which does not result in termination of this Agreement, either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of any such Underwriter under this Agreement.

10. Miscellaneous.

The respective indemnities, contribution agreements, representations, warranties and other statements of the Company, its officers and directors and of the several Underwriters set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, and will survive delivery of and payment for the Securities, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or by or on behalf of the Company, the officers or directors of the Company or any controlling person of the Company, (ii) acceptance of the Securities and payment for them hereunder and (iii) termination of this Agreement.

If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company agrees to reimburse the several Underwriters for all out-of-pocket expenses (including the fees and disbursements of counsel) reasonably incurred by them.

-19-

Except as otherwise provided, this Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Underwriters, any controlling persons referred to herein and their respective successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Securities from any of the several Underwriters merely because of such purchase.

This Agreement shall be governed and construed in accordance with the laws of the State of New York.

The Securities are to be issued pursuant to the provisions of an indenture (the "Senior Indenture") to be dated as of September 10, 1997 between the Company and Texas Commerce Bank, National Association, as trustee (the "Trustee"). The terms of the Securities are set forth in resolutions of the Pricing Committee of the Board of Directors of the Company dated as of the date hereof (the "Resolutions").

The Company has prepared and filed with the Securities and Exchange Commission (the "Commission") in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively called the "Act"), a registration statement on Form S-3 (Registration No. 333-32471), including a prospectus relating to the Securities, which may be amended. The registration statement as amended at the time when it became effective, including all documents or information incorporated or deemed to be incorporated by reference therein is referred to as the "Registration Statement"; and the prospectus in the form first used to confirm sales of Securities, (including (a) the information contained in any prospectus supplement relating to the Securities or deemed to be part of the Registration Statement at effectiveness pursuant to Rule 430A or Rule 434 of the Act, and (b) any documents or information incorporated or deemed to be incorporated by reference into such prospectus), are hereinafter referred to as the "Prospectus". Any registration statement (including any amendment or supplement thereto or information which is deemed to be a part thereof) filed by the Company under Rule 462(b) of the Act (a "Rule 462(b) Registration Statement") shall be deemed to be a part of the Registration Statement. If the


Company elects to rely on Rule 434 under the Act, all references to the Prospectus shall be deemed to also include, without limitation, the form of prospectus and term sheet (a "Term Sheet"), taken together, provided to the Underwriters by the Company in reliance on Rule 434 under the Act (the "Rule 434 Prospectus"). All references in this Agreement to financial statements and schedules and other information which is "contained," "included," "described" or "stated" in the Registration Statement or the Prospectus (and all references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or the Prospectus shall be deemed to mean and include, without limitation, even through not specifically stated, any document filed under the Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the "Exchange Act") which is or is deemed to be incorporated by reference in the Registration Statement or the Prospectus after the effective date, as the case may be.

(r) In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties).

(b) The indemnity agreement contained in paragraph 7(a), with respect to any preliminary prospectus, shall not inure to the benefit of any Underwriter to the extent that any loss, claim, damage or liability results from the fact that a copy of the Prospectus was not sent or given by or on behalf of such Underwriter to the person asserting any such loss, claim, damage or liability to the extent that the Prospectus would have cured the defect giving rise to such loss, claim, damage, liability or judgment if such Underwriter shall have been provided with the number of copies of the Prospectus requested by such Underwriter and it is judicially determined that such delivery was required under the Securities Act and was not so made.

(c) In case any action shall be brought against any Underwriter or any person controlling such Underwriter, based upon any preliminary prospectus, the Registration Statement or the Prospectus or any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such Underwriter shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses. Any Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the employment of such counsel has been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel, or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the Company and such Underwriter or such controlling person shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Underwriters and controlling persons, which firm shall be designated in writing by Donaldson, Lufkin & Jenrette Securities Corporation and that all such fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written consent, but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any Underwriter and any such controlling person from and against any loss or liability by reason of such settlement. Notwithstanding the immediately preceding sentence, if in any case where the fees and expenses of counsel are at the expense of the Company and an indemnified party shall have requested the Company to reimburse the indemnified party for such fees and expenses of counsel as incurred, the Company agrees that it shall be liable for any settlement of any action effected without its written consent if (i) such settlement is entered into more than forty business days after the receipt by the Company of the aforesaid request and (ii) the Company shall have failed to reimburse the indemnified party in accordance with such request for reimbursement prior to the date of such settlement. The Company shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity

-11-

could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, and any person controlling the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only with reference to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus or any preliminary prospectus. In case any action shall be brought against the Company, any of its directors, any such officer or any person controlling the Company based on the Registration Statement, the Prospectus or any preliminary prospectus and in respect of which indemnity may be sought against any Underwriter, the Underwriter shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), and the Company, its directors, any such officers and any person controlling the Company shall have the rights and duties given to the Underwriter, by Section 7(c) hereof.

(e) If the indemnification provided for in this Section 7 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, bear to the total price to the public of the Securities, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company and the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding

-12-

paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 7(e) are several in proportion to the respective number of Securities purchased by each of the Underwriters hereunder and not joint.

(f) The Company hereby designates CT Corporation Systems, Inc., 1633 Broadway, New York, New York 10019, (a Delaware corporation) as its authorized agent, upon which process may be served in any action, suit or proceeding which may be instituted in any state or federal court in the State of New York by any Underwriter or person controlling an Underwriter asserting a claim for indemnification or contribution under or pursuant to this Section 7, and the Company will accept the jurisdiction of such court in such action, and waives, to the fullest extent permitted by applicable law, any defense based upon lack of personal jurisdiction or venue. A copy of any such process shall be sent or given to the Company, at the address for notices specified in Section 10 hereof.

8. Conditions of Underwriters' Obligations. The several obligations of the Underwriters under this Agreement are subject to the satisfaction of each of the following conditions:

(viii) the execution, delivery and performance of this Agreement, the Senior Indenture and the Securities by the Company, compliance by the Company with all the provisions hereof and thereof and the consummation of the transactions contemplated hereby and thereby will not require any consent, approval, authorization or other order of any court, regulatory body, administrative agency or other governmental body (except such as may be required under the Act or other securities or Blue Sky laws) and will not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws of the Company;

(e) You shall have received on the Closing Date an opinion (satisfactory to you and counsel for the Underwriters), dated the Closing Date, of Gregory T. Sangalis, General Counsel to the Company, to the effect that:

(ii) the Company and each of its Material Subsidiaries is duly qualified and is in good standing as a foreign corporation authorized to do business in each jurisdiction in which the nature of its business or its ownership or leasing of property requires such qualification, except where the failure to be so qualified would not have a material adverse effect on the Company and its subsidiaries, taken as a whole;

(vi) the execution, delivery and performance of this Agreement, the Senior Indenture and the Securities by the Company, compliance by the Company with all the provisions hereof and thereof and the consummation of the transactions contemplated hereby and thereby will not conflict with or constitute a breach of any of the terms or provisions of, or a default under, the charter or by-laws of any of the Company's Material Subsidiaries or any agreement, indenture or other instrument to which the Company or any of its Material Subsidiaries is a party or by which the Company or any of its Material Subsidiaries or their respective properties are bound, or violate or conflict with any laws, administrative regulations or rulings or court decrees applicable to the Company or any of its subsidiaries or their respective properties;

-16-

(j) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating or outlook accorded any of the Company's securities by any "nationally recognized statistical rating organization," as such term is defined for purposes of Rule 436(g)(2) under the Act.

9. Effective Date of Agreement and Termination. This Agreement shall become effective upon the later of (i) execution of this Agreement and
(ii) when notification of the effectiveness of the Registration Statement has been released by the Commission.

This Agreement may be terminated at any time prior to the Closing Date by you by written notice to the Company if any of the following has occurred:
(i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any adverse change or development involving a prospective adverse change in the condition, financial or otherwise, of the Company or any of its subsidiaries or the earnings, affairs, or business prospects of the Company or any of its subsidiaries, whether or not arising in the ordinary course of business, which would, in your judgment, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (ii) any outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic conditions or in the financial markets of the United States or elsewhere that, in your judgment, is material and adverse and would, in your judgment, make it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus, (iii) the suspension or material limitation of trading in securities on the New York Stock Exchange, the American Stock Exchange or the NASDAQ National Market System or limitation on prices for securities on any such exchange or National Market System, (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects, or will materially and adversely affect, the business or operations of the Company or any

-18-

Subsidiary, (v) the declaration of a banking moratorium by either federal or New York State authorities or (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in your opinion has a material adverse effect on the financial markets in the United States.

If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase the Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase is not more than one-tenth of the total principal amount of the Securities to be purchased on such date by all Underwriters, each non-defaulting Underwriter shall be obligated severally, in the proportion which the principal amount of Securities set forth opposite its name in Schedule I bears to the total principal amount of Securities which all the non-defaulting Underwriters, as the case may be, have agreed to purchase, or in such other proportion as you may specify, to purchase the Securities which such defaulting Underwriter or Underwriters, as the case may be, agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities which any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Securities, without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date by all Underwriters and arrangements satisfactory to you and the Company for purchase of such Securities are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter and the Company. In any such case which does not result in termination of this Agreement, either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of any such Underwriter under this Agreement.

10. Miscellaneous. Notices given pursuant to any provision of this Agreement shall be addressed as follows: (a) if to the Company, to USA Waste Services, Inc., 1001 Fannin Street, Suite 4000, Houston, Texas 77002 and (b) if to any Underwriter or to you, to you c/o Donaldson, Lufkin & Jenrette Securities Corporation, 277 Park Avenue, New York, New York 10172, Attention:
Corporate Bond Syndicate Department, or in any case to such other address as the person to be notified may have requested in writing.

The respective indemnities, contribution agreements, representations, warranties and other statements of the Company, its officers and directors and of the several Underwriters set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, and will survive delivery of and payment for the Securities, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or by or on behalf of the Company, the officers or directors of the Company or any controlling person of the Company, (ii) acceptance of the Securities and payment for them hereunder and (iii) termination of this Agreement.

If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company agrees to reimburse the several Underwriters for all out-of-pocket expenses (including the fees and disbursements of counsel) reasonably incurred by them.

-19-

Except as otherwise provided, this Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Underwriters, any controlling persons referred to herein and their respective successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Securities from any of the several Underwriters merely because of such purchase.

This Agreement shall be governed and construed in accordance with the laws of the State of New York.

This Agreement may be signed in various counterparts which together shall constitute one and the same instrument.

If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fourteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent or proxy or of the holding by any Person of a Security shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the

7

Company if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in
Section 1406.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) The Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as the record date for the purpose of determining the Holders of Registered Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted to be given or taken by Holders of Securities of such series. If not set by the Company prior to the first solicitation of a Holder of Securities of such series made by any Person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 701) prior to such first solicitation or vote, as the case may be. With regard to any record date for action to be taken by the Holders of one or more series of Securities, only the Holders of Securities of such series on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant action.

(d) The principal amount and serial numbers of Registered Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(e) The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary, wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved in any other manner which the Trustee deems sufficient.

(f) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

(g) Without limiting the foregoing, a Holder entitled hereunder to give or take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any different part of such principal amount.

SECTION 105. Notices, Etc., to Trustee and Company.

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with a Responsible Officer of the Trustee at its Corporate Trust Office in Dallas, Texas or Houston, Texas, as appropriate, or

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture, to the attention of its Treasurer, or at any other address previously furnished in writing to the Trustee by the Company.

SECTION 106. Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of Securities of any event,

(1) such notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at the address of such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice; and

(2) such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper in The City of New York and in such other city or cities as may be specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders of Registered Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein.

In case by the reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice to Holders of Registered Securities given as provided herein.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or excluded, as the case may be.

SECURITY FORMS

SECTION 201. Forms Generally.

The Registered Securities, if any, of each series and the Bearer Securities, if any, of each series and related coupons shall be in substantially the form (including temporary or permanent global form) as shall be established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with law, or with the rules of any securities exchange or to conform to general usage, all as may, consistently herewith, be determined by the officers executing such Securities or coupons, as evidenced by their execution of the Securities or coupons. If temporary Securities of any series are issued in global form as permitted by Section 304, the form thereof shall be established as provided in the preceding sentence. A copy of the Board Resolution establishing the forms of Securities or coupons of any series (or any such temporary global Security) shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 303 for the authentication and delivery of such Securities (or any such temporary global Security) or coupons.

Unless otherwise specified as contemplated by Section 301, Securities in bearer form shall have interest coupons attached.

The definitive Securities and coupons, if any, shall be printed, lithographed or engraved on steel engraved borders or may be produced in any other manner, all as determined by the officers executing such Securities, as evidenced by their execution of such Securities or coupons.

SECTION 203. Securities in Global Form.

If Securities of a series are issuable in global form, as specified as contemplated by Section 301, then, notwithstanding clause (10) of Section 301 and the provisions of Section 302, any such Security shall represent such of the Outstanding Securities of such 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 be reduced to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Company Order to be delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of Section 303 and, if applicable, Section 304, 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 therein or in the

11

applicable Company Order. If a Company Order pursuant to Section 303 or 304 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 102 and need not be accompanied by an Opinion of Counsel.

The provisions of the last sentence of Section 303 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 303.

Notwithstanding the provisions of Sections 201 and 307, unless otherwise specified as contemplated by Section 301, payment of principal of and any premium and interest on any Security in permanent global form shall be made to the Person or Persons specified therein.

Any Book-Entry Security authenticated and delivered hereunder shall bear a legend in substantially the following form:

"This Security is a Book-Entry Security within the meaning of the Indenture hereinafter referred to and is registered in the name of a Depository or a nominee of a Depository. This Security is exchangeable for Securities registered in the name of a Person other than the Depository or its nominee only in the limited circumstances described in the Indenture, and no transfer of this Security (other than a transfer of this Security as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository) may be registered except in such limited circumstances."

All Securities of any one series and the coupons appertaining to any Bearer Securities of such series shall be substantially identical except, in the case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers' Certificate referred to above or in any such indenture supplemental hereto.

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate setting forth the terms of the series.

SECTION 302. Denominations.

Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, any Registered Securities of a series shall be issuable in denominations of $1,000 and any integral multiple thereof and any Bearer Securities of a series shall be issuable in the denomination of $5,000.

SECTION 303. Execution, Authentication, Delivery and Dating.

The Securities shall be executed on behalf of the Company by its Chairman of the Board, a Vice Chairman of the Board, its President, its Treasurer or its Chief Financial Officer, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Coupons shall bear the facsimile signature of the Treasurer or any Assistant Treasurer of the Company.

Securities and coupons bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with any coupons appertaining thereto, executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities; provided, however, that, unless otherwise provided with respect to such series, in connection with its original issuance, no Bearer Security shall be

14

mailed or otherwise delivered to any location in the United States; and provided, further, that, unless otherwise provided with respect to such series, a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in Exhibit A to this Indenture, dated no earlier than the Certification Date. If any Security shall be represented by a permanent global Bearer Security, then, for purposes of this
Section and Section 304, the notation of a beneficial owner's interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial owner's interest in such permanent global Security. Except as permitted by Section 306, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and canceled.

In authenticating Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating:

(a) that the forms of such Securities and coupons established by or pursuant to a Board Resolution as contemplated by Section 201 have been established in conformity with the provisions of this Indenture;

(b) if the terms of such Securities and any coupons have been established by or pursuant to a Board Resolution as permitted by
Section 301, that such terms have been established in conformity with the provisions of this Indenture; and

(c) that such Securities, together with any coupons appertaining thereto, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization and other laws of general applicability relating to or affecting creditors' rights and to general equity principles.

Such Opinion of Counsel shall also cover such other matters as the Trustee may reasonably request.

The Trustee shall not be required to authenticate such Securities the forms or terms of which have been established by or pursuant to a Board Resolution if the issue of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 301 and of the two preceding paragraphs, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraphs at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon issuance of the first Security of such series to be issued.

After the original issuance of the first Security of such series to be issued, any separate request by the Company that the Trustee authenticate Securities of such series for original issuance will be deemed to be a certification by the Company (which, subject to Section 601, the Trustee shall be fully protected in relying on) that it is in compliance with all conditions precedent provided for in this Indenture relating to the authentication and delivery of such Securities.

Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date of original issuance of the first Security of such series to be issued.

No Security or coupon shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security, or the Security to which such coupon appertains, a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly

15

authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 102 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 such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. Temporary Securities.

Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. In the case of any series issuable as Bearer Securities, such temporary Securities may be in global form. A temporary Bearer Security shall be delivered only in compliance with the conditions set forth in Section 303.

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company maintained pursuant to Section 1002 in a Place of Payment for such series for the purpose of exchanges of Securities of such series without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining thereto) the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like aggregate principal amount of definitive Securities of the same series and of like tenor of authorized denominations; provided, however, that no definitive Bearer Security shall be issued in exchange for a temporary Registered Security.

If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London office of a depositary or common depositary (the "Common Depositary"), for the benefit of Euro-clear and CEDEL S.A., for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security of a series (the "Exchange Date"), the Company shall deliver to the Trustee definitive Securities of that series in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities of that series without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged; provided, however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euro-clear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by CEDEL S.A. as to the portion of such temporary global Security held for its account then to be exchanged, each in the form set forth in Exhibit B to this Indenture. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 301, and if any combination

16

thereof is so specified, as requested by the beneficial owner thereof; provided, however, that no definitive Bearer Security or permanent global Security shall be delivered in exchange for a temporary Bearer Security except in compliance with the conditions set forth in Section 303.

Unless otherwise specified in the temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged on the Exchange Date for definitive Securities (and, where the form of the definitive Securities is not specified by the Holder, for an interest in a permanent global Security) of the same series and of like tenor unless, on or prior to the Exchange Date, such beneficial owner has not delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the form set forth in Exhibit A to this Indenture dated no earlier than the Certification Date, copies of which certificate shall be available from the offices of Euro-clear and CEDEL S.A., the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent and after the Exchange Date, the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities (and, where the form of the definitive Securities is not specified by the Holder, for an interest in a permanent global Security) of the same series and of like tenor following such beneficial owner's delivery to Euro-clear or CEDEL S.A., as the case may be, of a certificate in the form set forth in Exhibit A to this Indenture dated no earlier than the Certification Date. Unless otherwise specified in such temporary global Security, any exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like in the event that such Person does not take delivery of such definitive Securities in person at the offices of Euro-clear or CEDEL S.A. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall be delivered only outside the United States.

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series shall be payable to Euro-clear and CEDEL S.A. on such Interest Payment Date upon delivery by Euro-clear and CEDEL S.A. to the Trustee of a certificate or certificates in the form set forth in Exhibit B to this Indenture, for credit without further interest on or after such Interest Payment Date to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the form set forth in Exhibit A to this Indenture. Any interest so received by Euro-clear and CEDEL S.A. and not paid as herein provided shall be returned to the Trustee immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company in accordance with
Section 1003.

SECTION 305. Registration, Registration of Transfer and Exchange.

The Company shall cause to be kept at an office or agency to be maintained by the Company in accordance with Section 1002 a register (being the combined register of the Security Registrar and all transfer agents designated pursuant to Section 1002 for the purpose of registration of transfer of Securities and sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of each series of Registered Securities and the registration of transfers of such Registered Securities. The Company shall serve initially as "Security Registrar" for the purpose of registering Registered Securities and transfers of Registered Securities as herein provided.

Upon surrender for registration of transfer of any Registered Security of any series at the office or agency of the Company maintained pursuant to
Section 1002 for such purpose in a Place of Payment for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor.

17

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. Unless otherwise provided with respect to any series of Securities, Bearer Securities may not be issued in exchange for Registered Securities.

At the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture.

Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph. If the beneficial owners of interests in a permanent global Security are entitled to exchange such interests for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by
Section 301, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities of that series in an aggregate principal amount equal to the principal amount of such permanent global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered from time to time in accordance with instructions given to the Trustee and the Common Depositary (which instructions shall be in writing but need not comply with Section 102 or be accompanied by an Opinion of Counsel) by the Common Depositary or such other depositary or Common Depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the Company's agent for such purpose, to be exchanged, in whole or in part, for definitive Securities of the same series without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, a like aggregate principal amount definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged which, unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, as specified as contemplated by Section 301, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of that series is to be redeemed and ending on the relevant

18

Redemption Date; and provided, further, that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such permanent global Security shall be returned by the Trustee to the Common Depositary or such other depositary or Common Depositary referred to above in accordance with the instructions of the Company referred to above. If a Registered Security is issued in exchange for any portion of such permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee or any transfer agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar or any transfer agent duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption, or if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption, in whole or in part, except the unredeemed portion of any Registered Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that such Registered Security shall be simultaneously surrendered for redemption.

Notwithstanding the foregoing and except as otherwise specified or contemplated by Section 301, any Book-Entry Security shall be exchangeable pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities registered in the name of, and a transfer of a Book Entry Security of any series may be registered to, any Person other than the Depository for such Security or its nominee only if (i) such Depository notifies the Company that it is unwilling or unable to continue as Depository for such Book-Entry Security or if at any time such Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, (ii) the Company executes and delivers to the Trustee a Company Order that such Book-Entry Security shall be so exchangeable and the transfer thereof so registrable or (iii) there shall have occurred and be continuing an Event of Default, with respect to the Securities of such series. Upon the occurrence in respect of any Book-Entry Security of any series of any one or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be specified, such Book-Entry Security may be exchanged for Securities registered in the names of, and the transfer of such Book-Entry Security may be registered to, such Persons (including Persons other than the Depository with respect to such series and its nominees) as such Depository shall direct. Notwithstanding any other provision of this Indenture, any Security authenticated and delivered

19

upon registration of transfer of, or in exchange for, or in lieu of, any Book-Entry Security shall also be a Book-Entry Security and shall bear the legend specified in Section 204 except for any Security authenticated and delivered in exchange for, or upon registration of transfer of, a Book-Entry Security pursuant to the preceding sentence.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

If any mutilated Security or a Security with a mutilated coupon appertaining thereto is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security or coupon has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains.

If, after the delivery of such new Security, a bona fide purchaser of the original Security in lieu of which such new Security was issued presents for payment or registration such original Security, the Company and the Trustee shall be entitled to recover such new Security from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company or the Trustee in connection therewith.

In case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or coupon; provided, however, that the principal of and any premium and interest on Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an office or agency located outside the United States.

Upon the issuance of any new Security under this Section, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees, and expenses of the Trustee) connected therewith.

Every new Security of any series with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security or in exchange for a Security to which a destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and any such new Security and coupons, if any, shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series and their coupons, if any, duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons.

20

SECTION 307. Payment of Interest; Interest Rights Preserved.

Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Unless otherwise so provided, at the option of the Company, payment of interest on any Registered Security may be made by check mailed on or before the due date to the address of the Person entitled thereto as such address shall appear in the Security Register.

Any interest on any Registered Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Registered Securities of such series at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest on the Registered Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be then listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 308. Persons Deemed Owners.

Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of (and premium, if any) and

21

(subject to Sections 305 and 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Security or coupon be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Notwithstanding the foregoing, with respect to any Book-Entry Security, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by a Depository or impair, as between a Depository and holders of beneficial interests in any Book-Entry Security, the operation of customary practices governing the exercise of the rights of the Depository (or its nominee) as Holder of such Book-Entry Security.

SECTION 309. Cancellation.

All Securities and coupons surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Registered Securities and matured coupons so delivered shall be promptly canceled by the Trustee. All Bearer Securities and unmatured coupons so delivered shall be held by the Trustee and, upon instruction by a Company Order, shall be canceled or held for reissuance. Bearer Securities and unmatured coupons held for reissuance may be reissued only in replacement of mutilated, lost, stolen or destroyed Bearer Securities of the same series and like tenor or the related coupons pursuant to Section
306. All Bearer Securities and unmatured coupons held by the Trustee pending such cancellation or reissuance shall be deemed to be delivered for all purposes of this Indenture and the Securities. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities and coupons held by the Trustee shall be disposed of in accordance with its customary practice.

SECTION 310. Computation of Interest.

Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 1003 shall survive.

SECTION 402. Application of Trust Money.

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities, the coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited.

23

ARTICLE FIVE
REMEDIES

SECTION 501. Events of Default.

"Event of Default", wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order, rule or regulation of any administrative or governmental body), unless it is either inapplicable to a particular series of Securities or it is specifically deleted or modified in or pursuant to the terms of such series or in the form of Security of such series:

(1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or

(2) default in the payment of the principal of (or premium, if any, on) any Security of that series at its Maturity; or

(3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series; or

(4) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of a series of Securities other than that series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or

(5) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or

(6) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or

24

(7) any other Event of Default provided with respect to Securities of that series.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified in the terms thereof) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay

(A) all overdue interest on all Securities of that series,

(B) the principal of (and premium, if any, on) any Securities of that series which has become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel;

and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if

(1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

25

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities and coupons, the whole amount then due and payable on such Securities and coupons for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities and, in addition thereto, 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.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series and any related coupons by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim.

In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due 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 607.

No provision of this Indenture 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; provided, however, that the Trustee may, on behalf of Holders, vote for the election of a trustee of bankruptcy or similar official and be a member of a creditors' or other similar committee.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities or Coupons.

All rights of action and claims under this Indenture or the Securities or coupons may be prosecuted and enforced by the Trustee against third parties or otherwise without the possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities and coupons in respect of which such judgment has been recovered.

26

SECTION 506. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities or coupons, or both as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under
Section 607; and

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities and coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities and coupons for principal and any premium and interest, respectively.

In any case in which Securities are Outstanding that are denominated in more than one currency and the Trustee is directed to make ratable payments under this Section to Holders of such Securities, unless otherwise provided with respect to any series of Securities, the Trustee shall calculate the amount of such payments as follows: (i) as of the day the Trustee collects an amount under this Article, the Trustee shall, as to each Holder of a Security to whom an amount is due and payable under this Section that is denominated in a foreign currency, determine that amount in Dollars that would be obtained for the amount owing such Holder, using the rate of exchange at which in accordance with normal banking procedures the Trustee could purchase in The City of New York Dollars with such amount owing; (ii) calculate the sum of all Dollar amounts determined under (i) and add thereto any amounts due and payable in Dollars; and (iii) using the individual amounts determined in (i) or any individual amounts due and payable in Dollars, as the case may be, as a numerator, and the sum calculated in (ii) as a denominator, calculate as to each Holder of a Security to whom an amount is owed under this Section the fraction of the amount collected under this Article payable to such Holder. Any expenses incurred by the Trustee in actually converting amounts owing Holders of Securities denominated in a currency other than that in which any amount is collected under this Article shall be likewise (in accordance with this paragraph) borne ratably by all Holders of Securities to whom amounts are payable under this Section.

To the fullest extent allowed under applicable law, if for the purpose of obtaining judgment against the Company in any court it is necessary to convert the sum due in respect of the principal of, or premium, if any, or interest on, 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 Business Day in The City of New York next preceding that on which final judgment is given. Neither the Company nor the Trustee shall be liable for any shortfall nor shall either of them benefit from any windfall in payments to Holders of Securities under this
Section caused by a change in exchange rates between the time the amount of a judgment against the Company 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 such judgment shall discharge all amounts owed by the Company on the claim or claims underlying such judgment.

SECTION 507. Limitation on Suits.

No Holder of any Security of any series or any related coupons shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

27

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60- day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.

Notwithstanding any other provision in this Indenture, the Holder of any Security or coupon shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Sections 305 and 307) any interest on such Security or payment of such coupon on the Stated Maturity or Maturities expressed in such Security or coupon (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies.

If the Trustee or any Holder of a Security or coupon has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities and coupons shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the

28

Holders of Securities or coupons may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities or coupons, as the case may be.

SECTION 512. Control by Holders of Securities.

The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that

(1) such direction shall not be in conflict with any rule of law or with this Indenture;

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

(3) the Trustee shall not be obligated to take any action unduly prejudicial to Holders not joining in such direction or involving the Trustee in personal liability.

SECTION 513. Waiver of Past Defaults.

The Holders of a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to the Securities of such series and its consequences, except a default

(1) in the payment of the principal of or any premium or interest on any Security of such series, or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such 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 514. 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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company.

SECTION 515. Waiver of Stay or Extension Laws.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) 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.

30

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; and

(7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

The Trustee or any Authenticating Agent shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

SECTION 605. May Hold Securities.

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and coupons and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 607. Compensation and Reimbursement.

The Company agrees

(1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) except as otherwise expressly provided herein, to reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(3) to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder.

31

As security for the performance of the obligations of the Company under this Section the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities.

SECTION 608. Disqualification; Conflicting Interests.

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

SECTION 609. Corporate Trustee Required; Eligibility.

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 of America, any State thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal or State authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. No obligor upon any Security issued under this Indenture or a person directly or indirectly controlling, controlled by or under common control with such obligor shall serve as Trustee under this Indenture.

SECTION 610. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611.

(b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Trustee and to the Company.

(d) If at any time:

(1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or

(2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or a public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in

32

any case, (i) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (ii) subject to Section 514, any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, 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 series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders of Securities of such series and accepted appointment in the manner required by Section 611, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. Such court may thereupon, after such notice, if any, as it may deem proper, appoint a successor Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee, with like effect as if originally named Trustee hereunder; but on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Any Trustee ceasing to act shall, nevertheless, retain a prior lien upon all property or funds held or collected by such Trustee to secure any amounts then due it pursuant to the provisions of
Section 607.

(b) In case of the appointment hereunder 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 series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts 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

33

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, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees as co-trustees of the same trust and that 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; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(c) Upon request of any successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. 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 such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 613. Preferential Collection of Claims Against Company.

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

SECTION 614. Appointment of Authenticating Agent.

The Trustee may, by an instrument in writing, appoint an Authenticating Agent or Agents with respect to one or more series of Securities which may be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue or upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia (or, if Bearer Securities, organized and doing business under the laws of the country in which the Bearer Securities are eligible), authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority (or, if Bearer Securities, an authority of the country in which the Bearer Securities are eligible). If such Authenticating Agent publishes reports of

34

condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of such Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or such Authenticating Agent.

An Authenticating Agent may, and if it shall cease to be eligible shall, resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such notice of resignation or upon such termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payment, subject to the provisions of Section 607.

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have been endorsed thereon, in addition to the Trustee's certificate of authentication, an alternative certificate of authentication in the following form:

"This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.


As Trustee

By:
As Authenticating Agent

By:

Authorized Officer"

If all the Securities of a series may not be originally issued at one time, and if the Company has an Affiliate eligible to be appointed as an Authenticating Agent hereunder or the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 102 and need not be accompanied by an Opinion of Counsel), shall appoint in accordance with this
Section an Authenticating Agent (which, if so requested by the Company, shall be such

35

Affiliate of the Company) having an office in a Place of Payment designated by the Company with respect to such series of Securities.

COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities, any coupons appertaining thereto and this Indenture. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, any interest due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several coupons for such interest installments as are evidenced thereby as they severally mature.

SECTION 1002. Maintenance of Office or Agency.

If Securities of a series are issuable only as Registered Securities, the Company will maintain in each Place of Payment for such series an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company will maintain (A) in the Borough of Manhattan, The City of New York, an office or agency where any Registered Securities of that series may be presented or surrendered for payment, where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered for payment in the circumstances described in the following paragraph (and not otherwise), (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States, an office or agency where Securities of that series and related coupons may be presented and surrendered for payment (including payment of any additional amounts payable on Securities of that

40

series pursuant to Section 1004); provided, however, that if the Securities of that series are listed on The International Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange, and (C) subject to any laws or regulations applicable thereto, in a Place of Payment for that series located outside the United States an office or agency where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee and prompt notices to the Holders as provided in Section 106 of the location, and any change in the location, of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency in respect of any series of Securities or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders of Securities of that series may be made and notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of that series and the related coupons may be presented and surrendered for payment (including payment of any additional amounts payable on Bearer Securities of that series pursuant to Section 1004) at any Paying Agent for such series located outside the United States, and the Company hereby appoints the same as its agents to receive such respective presentations, surrenders, notices and demands.

No payment of principal, premium or interest on Bearer Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States provided, however, that, if the Securities of a series are denominated and payable in Dollars, payment of principal of and any premium and interest on any Bearer Security (including any additional amounts payable on Securities of such series pursuant to Section 1004) shall be made at the office of the Company's Paying Agent in the Borough of Manhattan, The City of New York, if (but only if) payment in Dollars of the full amount of such principal, premium, interest or additional amounts, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions.

The Company may also from time to time designate one or more other offices or agencies where Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to so maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee and the Holders of any such designation or rescission and of any other change in the location of any such other office or agency.

SECTION 1003. Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of and any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure to so act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal of and any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal and any premium or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure to so act.

41

The Company will cause each Paying Agent for any series of Securities (other than the Company or the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, and upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and any premium or interest on any Security of any series and remaining unclaimed for two years after such principal and any premium or interest has become due and payable shall be paid to the Company on Company Request (unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law), or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or any coupon appertaining thereto shall (unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law) thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 1004. Additional Amounts.

If the Securities of a series provide for the payment of additional amounts, the Company will pay to the Holder of any Security of such series or any coupon appertaining thereto additional amounts as 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 payment of any related coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of additional amounts provided for in this Section to the extent that, in such context, additional amounts are, were or would be payable in respect thereof pursuant to the provisions of this
Section 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 such express mention is not made.

If the Securities of a series provide for the payment of additional amounts, at least 10 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 10 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 will 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 such 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 or any related coupons 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 such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities or coupons and the Company

42

will pay to the Trustee or such 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.

SECTION 1005. Purchase of Securities by Company or Subsidiary.

If and so long as the Securities of a series are listed on The International Stock Exchange of the United Kingdom and the Republic of Ireland Limited and such stock exchange shall so require, the Company will not, and will not permit any of its Subsidiaries to, purchase any Securities of that series by private treaty at a price (exclusive of expenses and accrued interest) which exceeds 120% of the mean of the nominal quotations of the Securities of that series as shown in The Stock Exchange Daily Official List for the last trading day preceding the date of purchase.

SECTION 1006. Statement by Officer as to Default.

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company's compliance with all conditions and covenants under this Indenture. For purposes of this Section 1006, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

SECTION 1007. Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 1005 with respect to the Securities of any series if before the time for such compliance the Holders of a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

SECTION 1008. Limitation on Liens.

SECTION 1102. Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In the case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities of such series to be redeemed.

Notice of redemption shall be given in the manner provided in Section 106 to the Holders of Securities to be redeemed not less than 30 or more than 60 days prior to the Redemption Date.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed, and that on and after the Redemption Date, upon surrender of the Securities, new Securities of such series in principal amount equal to the unredeemed part thereof will be issued,

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(5) the place or places where such Securities, together in the case of Bearer Securities with all coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price, and

(6) that the redemption is for a sinking fund, if such is the case.

A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed.

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 request, by the Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 1105. Deposit of Redemption Price.

On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date.

SECTION 1106. Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of coupons for

49

such interest, and provided, further, that, unless otherwise specified as contemplated by Section 301, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of those coupons.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

SECTION 1107. Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at a Place of Payment thereof (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

(2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund

50

payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

SECTION 1203. Redemption of Securities for Sinking Fund.

Not less than 45 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee a Company Order 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, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so credited. Not less than 30 days before each such sinking fund payment date the Company or the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 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 1104.

Anything in this Article Thirteen to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in
Section 1304 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 1302 or 1303 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities of such series shall be revived and reinstated as though no deposit had occurred pursuant to this Article Thirteen until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1302 or 1303; provided, however, that if the Company makes any payment of principal of or any premium or interest on any Security following the

53

This Security is one of a series designated as the 7% Senior Notes due 2004 of the Company, limited in aggregate principal amount to $300,000,000.

1. Interest.

USA Waste Services, Inc., a Delaware corporation (hereinafter called the "Company," which term includes any successors under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 7% per annum. To the extent it is lawful, the Company promises to pay interest on any interest payment due but unpaid on such principal amount at a rate of 7% per annum.

The Company will pay interest semi-annually on October 1 and April 1 of each year (each an "Interest Payment Date"), commencing April 1, 1998. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from September 15, 1997. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

2. Method of Payment.

The Company shall pay interest on the Securities (except Defaulted Interest) to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Any such interest not so punctually paid ("Defaulted Interest"), may be paid to the persons who are registered Holders at the close of business on a Special Record Date for the payment of such Defaulted Interest, or in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may then be listed if such manner of payment shall be deemed practicable by the Trustee, as more fully provided in the Indenture referred to below. Except as provided below, the Company shall pay principal and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts ("U.S. Legal Tender"). Payments in respect of the Book-Entry Securities (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. Payments in respect of Securities in definitive form (including principal, premium, if any, and interest) will be made at the office or agency of the Company maintained for such purpose within the Borough of Manhattan, The City of New York, or at the option of the Company, payment of interest may be made by check mailed to the Holders on the Regular Record Date or on the Special Record Date at their addresses set forth in the Security Register of Holders.

5. Redemption.

The Securities will be redeemable at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days notice to each Holder of Securities, at a redemption price equal to the Make-Whole Price. "Make-Whole Price" means an amount equal to the greater of (i) 100% of the principal amount of such Securities and (ii) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case accrued and unpaid interest to the date of redemption. Unless the Company defaults in payment of the Make-Whole Price, on and after the date of redemption, interest will cease to accrue on the Securities or portions thereof called for redemption.

"Adjusted Treasury Rate" means, with respect to any date of redemption, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such date of redemption, plus 0.20%.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Securities.

"Comparable Treasury Price" means, with respect to any date of redemption, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day preceding such date of redemption, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations of U.S. Government Securities", or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, (A) the average of the Reference Treasury Dealer Quotations for such date of redemption, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

"Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company.

"Reference Treasury Dealer" means each of Donaldson, Lufkin & Jenrette Securities Corporation, Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities Inc. and BT Alex. Brown Incorporated and their respective successors; provided, however, that if any of the foregoing shall not be a primary U.S. government securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer.

"Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any date of redemption, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such date of redemption.

In the case of a partial redemption, the Company or the Trustee shall select the Securities or portions thereof for redemption by such method as the Company or the Trustee shall deem fair and appropriate. The Securities may be redeemed in part in multiplies of $1,000 only.

Any such redemption will also comply with Article Eleven of the Indenture.

4

Notice of redemption will be given in the manner provided in the Indenture to the Holders of Securities to be redeemed not less than 30 days and not more than 60 days prior to the Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Make-Whole Price and, except as set forth in the Indenture, from and after such Redemption Date, (unless the Company shall default in the payment of the Make-Whole Price), the Securities called for redemption will cease to bear interest and the only right of the Holders of such Securities will be to receive payment of the Make-Whole Price.

6. Denominations; Transfer; Exchange.

The Securities are issued in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of, or exchange, Securities in accordance with the Indenture. The Securities Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

7. Person Deemed Owners.

The registered Holder of a Security may be treated as the owner of it for all purposes.

Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

9. Defaults and Remedies.

If an Event of Default occurs and is continuing, then in every such case, the Trustee or the Holders of 25% in aggregate principal amount of the Securities then outstanding may declare the principal amount of all the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after the unpaid principal amount of the Securities shall have been so declared due and payable and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all overdue installments of interest, if any, upon all of the Securities and the principal of any and all Securities which shall have become due otherwise than by acceleration and any interest thereon at the rate prescribed therefor herein and, to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor herein, as well as the reasonable compensation, disbursements, expenses and advances of the Trustee, and any and all defaults under the Indenture, other than the nonpayment of such portion of the principal amount of and accrued interest, if any, on such Securities which shall become due by acceleration, shall have been cured or shall have been waived or provision deemed by the Trustee to be adequate shall have been made therefor -- then in every such case the Holders of a majority in aggregate principal amount of the Securities then Outstanding, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences; but no such rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

10. Trustee Dealings with Company.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from,

5

and perform services for the Company or its Affiliates or any subsidiary of the Company's Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not the Trustee.

No representation is made as to the accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

8. Amendment; Supplement; Waiver.

Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the written consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

If an Event of Default occurs and is continuing, then in every such case, the Trustee or the Holders of 25% in aggregate principal amount of the Securities then outstanding may declare the principal amount of all the Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after the unpaid principal amount of the Securities shall have been so declared due and payable and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all overdue installments of interest, if any, upon all of the Securities and the principal of any and all Securities which shall have become due otherwise than by acceleration and any interest thereon at the rate prescribed therefor herein and, to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor herein, as well as the reasonable compensation, disbursements, expenses and advances of the Trustee, and any and all defaults under the Indenture, other than the nonpayment of such portion of the principal amount of and accrued interest, if any, on such Securities which shall become due by acceleration, shall have been cured or shall have been waived or provision deemed by the Trustee to be adequate shall have been made therefor -- then in every such case the Holders of a majority in aggregate principal amount of the Securities then Outstanding, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences; but no such rescission and annulment shall extend to or shall affect any subsequent default, or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates or any subsidiary of the Company's Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not the Trustee.
