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
<PAGE>   2
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.  The Company is advised by you that
the Underwriters propose (i) to make a public offering of their respective
portions of the Securities as soon after the effective date of the Registration
Statement as in your judgment is advisable and (ii) initially to offer the
Securities upon the terms set forth in the Prospectus.

         4.      Delivery and Payment.  Delivery to the Underwriters of and
payment for the Securities shall be made at 10:00 A.M., New York City time, on
the third or fourth business day unless otherwise permitted by the Commission
pursuant to Rule 15c6-1 of the Exchange Act (the "Closing Date") following the
date of the initial public offering at such place as you shall designate.  The
Closing Date and the location of delivery of and the form of payment for the
Securities may be varied by agreement between you and the Company.

         The Securities shall be registered in such names and issued in such
denominations as you shall request in writing not later than two full business
days prior to the Closing Date.  A global certificate for the Securities shall
be made available to you for inspection not later than 9:30 A.M., New York City
time, on the business day next preceding the Closing Date.  A global
certificate for the Securities in definitive form evidencing the Securities
shall be delivered to you on the Closing Date with any transfer taxes thereon
duly paid by the Company, for the respective accounts of the several
Underwriters, against payment of the Purchase Price therefor by wire transfer
in same day funds to an account specified by the Company.

         5.      Agreements of the Company.  The Company agrees with you:

                 (a)      Immediately following the determination of the
         Purchase Price, to prepare, and file or transmit for filing with the
         Commission in accordance with Rule 424(b) of the Act, copies of a
         prospectus supplement relating to the Securities and containing all
         information required under the Act.





                                      -2-
<PAGE>   3
                 (b)      To advise you promptly and, if requested by you, to
         confirm such advice in writing, (i) when the Registration Statement
         has become effective and when any post-effective amendment to it
         becomes effective, (ii) of the receipt of comments from the Commission
         relating to the Registration Statement, (iii) of any request by the
         Commission for amendments to the Registration Statement or amendments
         or supplements to the Prospectus or for additional information, (iv)
         of the issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or of the suspension of
         qualification of the Securities for offering or sale in any
         jurisdiction, or the initiation of any proceeding for such purposes,
         and (v) of the happening of any event during the period referred to in
         paragraph (e) below which makes any statement of a material fact made
         in the Registration Statement or the Prospectus untrue or which
         requires the making of any additions to or changes in the Registration
         Statement or the Prospectus in order to make the statements therein
         not misleading.  If at any time the Commission shall issue any stop
         order suspending the effectiveness of the Registration Statement, the
         Company will make every reasonable effort to obtain the withdrawal or
         lifting of such order at the earliest possible time.

                 (c)      To furnish to you, without charge, five signed copies
         of the Registration Statement as first filed with the Commission and
         of each amendment to it, including all exhibits, and to furnish to you
         and each Underwriter designated by you such number of conformed copies
         of the Registration Statement as so filed and of each amendment to it,
         without exhibits, as you may reasonably request.

                 (d)      Prior to the termination of the offering of
         Securities, not to (i) file any 462(b) Registration Statement, (ii)
         file any amendment or supplement to the Registration Statement, (iii)
         file any document under the Exchange Act which shall be deemed to be
         incorporated by reference into the Prospectus, or (iv) make any
         amendment or supplement to the Prospectus (including the issuance or
         filing of any Term Sheet) of which you shall not previously have been
         advised or to which you shall reasonably object; and to prepare and
         file with the Commission, promptly upon your reasonable request, any
         462(b) Registration Statement, Term Sheet or amendment or supplement
         to the Registration Statement or the Prospectus which may be necessary
         or advisable in connection with the distribution of the Securities by
         you, and to use its best efforts to cause the same to become promptly
         effective.

                 (e)      From time to time for such period as in the opinion
         of counsel for the Underwriters a prospectus is required by law to be
         delivered in connection with sales by an Underwriter or a dealer, to
         furnish to each Underwriter and dealer as many copies of the
         Prospectus (and of any amendment or supplement to the Prospectus) as
         such Underwriter or dealer may reasonably request.

                 (f)      If during the period specified in paragraph (e) any
         event shall occur as a result of which, in the opinion of counsel for
         the Underwriters, it becomes necessary to amend or supplement the
         Prospectus in order to make the statements therein, in the light of
         the circumstances when the Prospectus is delivered to a purchaser, not
         misleading, or if it is necessary to amend or supplement the
         Prospectus to comply with any law, forthwith to prepare and file with
         the Commission an appropriate amendment or supplement to the
         Prospectus so that the statements in the Prospectus, as so amended or
         supplemented, will not, in the light of the circumstances when it is
         so delivered, be misleading, or so that the Prospectus will comply
         with law, and to furnish to





                                      -3-

         of copies thereof as such Underwriter or dealers may reasonably

         or Blue Sky laws of such jurisdictions as you may request, to continue
         such qualification in effect so long as required for distribution of
         the Securities and to file such consents to service of process or
         other documents as may be necessary in order to effect such
         registration or qualification.

         securityholders as soon as reasonably practicable an earnings
         statement covering a period of at least twelve months after the

         date) which shall satisfy the provisions of Section 11(a) of the Act.

         this Agreement, (i) to mail as soon as reasonably practicable after

         a material fact or omit to state a material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, except that the representations and
         warranties set forth in this paragraph (b) do not apply to statements
         or omissions in the Registration Statement or the Prospectus based
         upon information relating to any Underwriter furnished to the Company
         in writing by such Underwriter through you expressly for use therein.

                 (c)      Any term sheet or prospectus subject to completion
         provided by the Company to the Underwriters for use in connection with
         the offering and sale of the Securities pursuant to Rule 434 under the
         Act together are not materially different from the prospectus included

         deemed to be incorporated by reference in the Prospectus pursuant to
         Item 12 of Form S-3 under the Act, at the time they were, or hereafter

         Exchange Act, and, when read together with other information in the
         Prospectus, at the time the Registration Statement became effective
         and as of the Closing Date, and during the period specified in Section
         5(e), did not and will not contain an untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.

                 (d)      Each preliminary prospectus filed as part of the
         Registration Statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Act, and each Rule
         462(b) Registration Statement, if any, complied when so filed in all
         material respects with the Act; and did not contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading.

                 (e)      Annex I is an accurate and complete list of all
         subsidiaries of the Company (the "Material Subsidiaries") which
         accounted for more than $35.0 million of revenues during the six
         months ended June 30, 1997 or which, as of June 30, 1997, had assets
         in excess of $125.0 million.  The Company and each of its subsidiaries
         has been duly incorporated, is validly existing as a corporation in
         good standing under the laws of its jurisdiction of incorporation and
         has the corporate power and authority to carry on its business as it
         is currently being conducted and to own, lease and operate its
         properties, and each 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.

                 (f)      All of the outstanding shares of capital stock of, or
         other ownership interests in, each of the Company's subsidiaries have
         been duly authorized and validly issued and are fully paid and non-
         assessable, and are owned by the Company, free and clear of any
         security interest, claim, lien, encumbrance or adverse interest of any
         nature (other than liens created under the Credit Facility (as defined
         in the Registration Statement)).

                 (g)      All the outstanding shares of capital stock of the
         Company have been duly authorized and validly issued and are fully
         paid, non-assessable and not subject to any preemptive or similar
         rights.  Upon payment of the Purchase Price and delivery of
         certificates representing the Securities, each of the Underwriters
         will receive the Securities free and clear of all liens, security
         interests or encumbrances.

                 (h)      The Securities have been duly authorized and, when
         executed and authenticated in accordance with the provisions of the
         Senior Indenture and delivered to the Underwriters against payment
         therefor as provided by this Agreement, will be entitled to the
         benefits of the Senior Indenture, and will be valid and binding
         obligations of the Company, enforceable in accordance with their 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 to equitable principles of general applicability.

                 (i)      This Agreement 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
         enforcement of rights to indemnity and contribution hereunder may be
         limited by





                                      -6-
<PAGE>   7
         applicable laws or principles of public policy and subject to the
         qualifications that the enforceability of the Company's obligations
         hereunder may be limited by bankruptcy, insolvency, reorganization, or
         other laws relating to or affecting creditors' rights generally and by
         general principles of equity, regardless of whether such
         enforceability is considered in a proceeding in equity or at law).

                 (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-
<PAGE>   8
         ("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.

                 (u)      Coopers & Lybrand LLP and Coopers & Lybrand Chartered
         Accountants are independent public accountants with respect to the
         Company and Ernst & Young LLP are





                                      -8-

         independent public accountants with respect to United Waste Systems,
         Inc. ("United") as required by the Act.

                 (v)      The financial statements, together with related
         schedules and notes, forming part of the Registration Statement and
         the Prospectus (and any amendment or supplement thereto), present
         fairly the consolidated financial position, results of operations and
         changes in financial position of the Company and its subsidiaries
         (including United) on the basis stated in the Registration Statement
         at the respective dates or for the respective periods to which they
         apply; such statements and related schedules and notes have been
         prepared in accordance with generally accepted accounting principles
         consistently applied throughout the periods involved, except as
         disclosed therein; and the other financial and statistical information
         and data set forth in the Registration Statement and the Prospectus
         (and any amendment or supplement thereto) is, in all material
         respects, accurately presented and prepared on a basis consistent with
         such financial statements and the books and records of the Company and
         its subsidiaries (including United).  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.

                 (z)      Except as disclosed in the Prospectus, there are no
         business relationships or related party transactions required to be
         disclosed therein by Item 404 of Regulation S-K of the Commission.

                 (aa)     There is (i) no significant unfair labor practice
         complaint pending against the Company or any of its subsidiaries or,
         to the knowledge of the Company, threatened against any of them,
         before the National Labor Relations Board or any state or local labor
         relations board, and no significant grievance or significant
         arbitration proceeding arising out of or under any collective
         bargaining agreement is so pending against the Company or any of its
         subsidiaries or, to the best knowledge of the Company, threatened
         against any of them, and (ii) no significant strike, labor dispute,
         slowdown or stoppage pending against the Company or any of its
         subsidiaries or, to the best knowledge of the Company, threatened
         against it or any of its subsidiaries except for such actions
         specified in clause (i) or (ii) above, which, singly or in the
         aggregate could not reasonably be expected to have a material adverse
         effect on the Company and its subsidiaries, taken as a whole.

                 (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,

         or any development involving a prospective material adverse effect, in

         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-
<PAGE>   11
         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-
<PAGE>   12
         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-
<PAGE>   13
         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:

                 (a)      All the representations and warranties of the Company
         contained in this Agreement shall be true and correct on the Closing
         Date with the same force and effect as if made on and as of the
         Closing Date.

                 (b)      The Registration Statement shall have become
         effective not later than 5:00 P.M., (and in the case of a Registration
         Statement filed under 462(b) of the Act, not later than 10:00 P.M.)
         New York City time, on the date of this Agreement or at such later
         date and time as you may approve in writing, and at the Closing Date,
         no stop order suspending the effectiveness of the Registration
         Statement shall have been issued and no proceedings for that purpose
         shall have been commenced or shall be pending before or contemplated
         by the Commission.

                 (c)      (i) Since the date of the latest balance sheet
         included in the Registration Statement and the Prospectus, there shall
         not have been any material adverse change, or any development
         involving a prospective material adverse change, in the condition,
         financial or otherwise, or in the earnings, affairs or business
         prospects, whether or not arising in the ordinary course of business,
         of the Company, (ii) since the date of the latest balance sheet
         included in the Registration Statement and the Prospectus there shall
         not have been any change, or any development involving a prospective

         of the Company from that set forth in the Registration Statement and
         Prospectus, (iii) the Company and its subsidiaries shall have no
         liability or obligation, direct or contingent, which is material to
         the Company and its subsidiaries, taken as a whole, other than those
         reflected in the Registration Statement and the Prospectus and (iv) on
         the Closing Date you shall have received a certificate





                                      -13-

         Chief Financial Officer of the Company, confirming the matters set
         forth in paragraphs (a), (b), and (c) of this Section 8.

                 (d)      You shall have received on the Closing Date an
         opinion (satisfactory to you and counsel for the Underwriters), dated
         the Closing Date of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P.,

                 Underwriters against payment therefor as provided by this
                 Agreement, will be entitled to the benefits of the Senior

                 laws or principles of public policy and subject to the
                 qualifications that the enforceability of the Company's

                 affecting creditors' rights generally and by general
                 principles of equity (regardless of whether such
                 enforceability is considered in a proceeding in equity or at

                          (iv)    the Senior Indenture has been duly qualified

                 and is a valid and binding agreement of the Company,

                 insofar as such statements constitute a summary of legal
                 matters or documents referred to therein, fairly present the
                 information called for with respect to such legal matters or

                 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

                 a company "controlled" by an "investment company" within the
                 meaning of the Investment Company Act of 1940, as amended;

                          (x)     the Registration Statement, the Prospectus,
                 any supplement or amendment thereto and each document filed
                 pursuant to the Exchange Act and incorporated or deemed to be
                 incorporated by reference in the Prospectus (except for
                 financial statements, financial and statistical information
                 contained therein as to which no opinion need be expressed)
                 comply as to form in all material respects with the Act;

                 (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:

                          (i)     each of the Company's Material Subsidiaries
                 has been duly incorporated, is validly existing as a
                 corporation in good standing under the laws of its
                 jurisdiction of incorporation and has the corporate power and
                 authority required to carry on its business as it is currently
                 being conducted and to own, lease and operate its properties;

                          (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;

                          (iii)   all of the outstanding shares of capital
                 stock of, or other ownership interests in, each of the
                 Company's subsidiaries have been duly and validly authorized
                 and issued and are fully paid and non-assessable, and are
                 owned by the Company, free and clear of any security interest,
                 claim, lien, encumbrance or adverse interest of any nature
                 (other than liens created under the Credit Facility);

                          (iv)    all the outstanding shares of Common Stock
                 have been duly authorized and validly issued and are fully
                 paid, non-assessable and not subject to any statutory
                 preemptive rights or, to the knowledge of such counsel, any
                 other similar rights;

<PAGE>   16
                          (v)     neither the Company nor any of its Material
                 Subsidiaries is in violation of its respective charter or by-
                 laws and, to the best of such counsel's knowledge after due
                 inquiry, neither the Company nor any of its Material
                 Subsidiaries is 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 Material
                 Subsidiaries is a party or by which it or any of its
                 subsidiaries or their respective properties are bound;

                          (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;

                          (vii)   to such counsel's knowledge there are no
                 legal or governmental proceedings pending or threatened to
                 which the Company or any of its subsidiaries is a party or to
                 which any of their respective properties are subject which is
                 required to be described in the Registration Statement or the
                 Prospectus and is not so described, or of any contract or
                 other document which is required to be described in the
                 Registration Statement or the Prospectus or is required to be
                 filed as an exhibit to the Registration Statement which is not
                 described or filed as required; such counsel does not have any
                 reason to believe that the description of litigation in the
                 Prospectus is not accurate and complete in all material
                 respects;

                          (viii)  to such counsel's knowledge, except as
                 described in the Prospectus, neither the Company nor any of
                 its subsidiaries has violated any 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;

                          (ix)    to such counsel's knowledge, 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 in the manner described in the Prospectus 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; to such counsel's knowledge, 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, subject in each case to such qualification as may be
                 set forth in the Prospectus; and, except as described in the
                 Prospectus, such permits contain no restrictions that are
                 materially burdensome to the Company or any of its
                 subsidiaries;

                          (x)     to such counsel's knowledge, 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
                 as a result of filing the Registration Statement, which have
                 not been waived;

                          (xi)    such counsel believes that (except for
                 financial statements, financial and statistical information
                 contained therein, as aforesaid and except for that part of
                 the Registration Statement that constitutes the Form T-1) the
                 Registration Statement and the prospectus included therein at
                 the time the Registration Statement became effective did not
                 contain any untrue statement of a material fact or omit to
                 state a material fact required to be stated therein or
                 necessary to make the statements therein not misleading, and
                 that the Prospectus, as amended or supplemented, if applicable
                 (except for financial statements, and financial and
                 statistical information, as aforesaid) does not contain any
                 untrue statement of a material fact or omit to state a
                 material fact necessary in order to make the statements
                 therein, in the light of the circumstances under which they
                 were made, not misleading;

                          (xii)   all descriptions in the Prospectus of
                 statutes, regulations or legal or governmental proceedings in
                 all material respects are accurate and fairly present the
                 information required to be shown;

                 The opinion of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P.
         referred to in subsection (d) above shall contain a statement that
         such counsel believes that (except for financial statements and
         financial and statistical information contained therein, as aforesaid
         and except for that part of the Registration Statement that
         constitutes the Form T-1), the Registration Statement and the
         prospectus included therein at the time the Registration Statement
         became effective did not contain any untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, and that the
         Prospectus, as amended or supplemented, if applicable (except for
         financial statements and financial and statistical information, as
         aforesaid) does not contain any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading.  Liddell, Sapp, Zivley, Hill & LaBoon,
         L.L.P. in giving its opinions with respect to the matters covered by
         clauses (d)(ix) and (e)(xi) may state that its opinions and beliefs
         are based upon its participation in the preparation of the
         Registration Statement and Prospectus and any amendments or
         supplements thereto and review and discussion of the contents thereof,
         but are without independent check or verification except as specified.

                 In giving the opinions described in clause (d) and (e) above,
         such counsel may rely as to factual matters on information set forth
         in certificates of the Company or public officials.

                 The opinions of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P.
         and Gregory T. Sangalis described in paragraphs (d) and (e) above
         shall be rendered to you at the request of the Company and shall so
         state therein.

                 (f)      You shall have received on the Closing Date an
         opinion, dated the Closing Date, of McDermott, Will & Emery, counsel
         for the Underwriters, in form and substance satisfactory to you.

                 (g)      You shall have received a letter on and as of the
         Closing Date, in form and substance satisfactory to you, from each of
         Coopers & Lybrand L.L.P., Coopers & Lybrand Chartered Accountants and
         Ernst & Young LLP, independent public accountants, with respect to the
         financial statements and certain financial information contained in
         the Registration Statement and the Prospectus and substantially in the
         form and substance of the letter delivered to you by each of Coopers &
         Lybrand LLP, Coopers & Lybrand Chartered Accountants and Ernst & Young
         LLP, on the date of this Agreement.

                 (h)      The Company shall not have failed at or prior to the
         Closing Date to perform or comply with any of the agreements herein
         contained and required to be performed or complied with by the Company
         at or prior to the Closing Date.

                 (i)      The transactions contemplated by the Underwriting
         Agreement dated of even date herewith between you and the Company with
         respect to $300,000,000 principal amount of 7 1/8% Senior Notes due
         2007 of the Company (the "2007 Notes Underwriting Agreement") shall be
         consummated simultaneously with the transactions contemplated hereby.

                 (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-
<PAGE>   19
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.

         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.

Dear Sirs:

         USA Waste Services, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell $300,000,000 principal amount of its 7 1/8% Senior
Notes due 2007 (the "Securities"), to the several underwriters named in

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

Securities may be varied by agreement between you and the Company.

                 offering or sale in any jurisdiction, or the initiation of any
                 proceeding for such purposes, and (v) of the happening of any
                 event during the period referred to in paragraph (e) below
                 which makes any statement of a material fact made in the
                 Registration Statement or the Prospectus untrue or which
                 requires the making of any additions to or changes in the
                 Registration Statement or the Prospectus in order to make the
                 statements therein not misleading.  If at any time the
                 Commission shall issue any stop order suspending the
                 effectiveness of the Registration Statement, the Company will
                 make every reasonable effort to obtain the withdrawal or

         of the Registration Statement as first filed with the Commission and

         filing of any Term Sheet) of which you shall not previously have been
         advised or to which you shall reasonably object; and to prepare and

         or advisable in connection with the distribution of the Securities by
         you, and to use its best efforts to cause the same to become promptly
         effective.

                 (e)      From time to time for such period as in the opinion

         event shall occur as a result of which, in the opinion of counsel for
         the Underwriters, it becomes necessary to amend or supplement the
         Prospectus in order to make the statements therein, in the light of
         the circumstances when the Prospectus is delivered to a purchaser, not
         misleading, or if it is necessary to amend or supplement the
         Prospectus to comply with any law, forthwith to prepare and file with
         the Commission an appropriate amendment or supplement to the
         Prospectus so that the statements in the Prospectus, as so amended or

         so delivered, be misleading, or so that the Prospectus will comply
         with law, and to furnish to

         which the nature of its business or its ownership or leasing of
         property requires such qualification, except where the failure to be

         and its subsidiaries, taken as a whole.

                 (f)      All of the outstanding shares of capital stock of, or

         rights.  Upon payment of the Purchase Price and delivery of
         certificates representing the Securities, each of the Underwriters
         will receive the Securities free and clear of all liens, security
         interests or encumbrances.

                 (h)      The Securities have been duly authorized and, when
         executed and authenticated in accordance with the provisions of the
         Senior Indenture and delivered to the Underwriters against payment
         therefor as provided by this Agreement, will be entitled to the
         benefits of the Senior Indenture, and will be valid and binding
         obligations of the Company, enforceable in accordance with their 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 to equitable principles of general applicability.

                 (i)      This Agreement 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
         enforcement of rights to indemnity and contribution hereunder may be
         limited by





                                      -6-

         applicable laws or principles of public policy and subject to the
         qualifications that the enforceability of the Company's obligations
         hereunder may be limited by bankruptcy, insolvency, reorganization, or
         other laws relating to or affecting creditors' rights generally and by
         general principles of equity, regardless of whether such
         enforceability is considered in a proceeding in equity or at law).

                 (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.

         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.

                 (u)      Coopers & Lybrand LLP and Coopers & Lybrand Chartered
         Accountants are independent public accountants with respect to the
         Company and Ernst & Young LLP are





                                      -8-
<PAGE>   9
         independent public accountants with respect to United Waste Systems,
         Inc. ("United") as required by the Act.

                 (v)      The financial statements, together with related
         schedules and notes, forming part of the Registration Statement and
         the Prospectus (and any amendment or supplement thereto), present
         fairly the consolidated financial position, results of operations and
         changes in financial position of the Company and its subsidiaries
         (including United) on the basis stated in the Registration Statement
         at the respective dates or for the respective periods to which they
         apply; such statements and related schedules and notes have been
         prepared in accordance with generally accepted accounting principles
         consistently applied throughout the periods involved, except as
         disclosed therein; and the other financial and statistical information
         and data set forth in the Registration Statement and the Prospectus
         (and any amendment or supplement thereto) is, in all material
         respects, accurately presented and prepared on a basis consistent with
         such financial statements and the books and records of the Company and
         its subsidiaries (including United).  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.

                 (z)      Except as disclosed in the Prospectus, there are no
         business relationships or related party transactions required to be
         disclosed therein by Item 404 of Regulation S-K of the Commission.

                 (aa)     There is (i) no significant unfair labor practice
         complaint pending against the Company or any of its subsidiaries or,
         to the knowledge of the Company, threatened against any of them,
         before the National Labor Relations Board or any state or local labor
         relations board, and no significant grievance or significant
         arbitration proceeding arising out of or under any collective
         bargaining agreement is so pending against the Company or any of its
         subsidiaries or, to the best knowledge of the Company, threatened
         against any of them, and (ii) no significant strike, labor dispute,
         slowdown or stoppage pending against the Company or any of its
         subsidiaries or, to the best knowledge of the Company, threatened
         against it or any of its subsidiaries except for such actions
         specified in clause (i) or (ii) above, which, singly or in the
         aggregate could not reasonably be expected to have a material adverse
         effect on the Company and its subsidiaries, taken as a whole.

                 (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-
<PAGE>   10
         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-
<PAGE>   11
         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-
<PAGE>   12
         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-
<PAGE>   13
         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

                 (b)      The Registration Statement shall have become
         effective not later than 5:00 P.M., (and in the case of a Registration

         shall have been commenced or shall be pending before or contemplated
         by the Commission.

                 (c)      (i) Since the date of the latest balance sheet

         involving a prospective material adverse change, in the condition,
         financial or otherwise, or in the earnings, affairs or business
         prospects, whether or not arising in the ordinary course of business,
         of the Company, (ii) since the date of the latest balance sheet

                          (iv)    the Senior Indenture has been duly qualified

                 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,

                 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;

                          (ix)    the Company is not an "investment company" or
                 a company "controlled" by an "investment company" within the

                 incorporated by reference in the Prospectus (except for
                 financial statements, financial and statistical information
                 contained therein as to which no opinion need be expressed)
                 comply as to form in all material respects with the Act;

                 (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:

                          (i)     each of the Company's Material Subsidiaries
                 has been duly incorporated, is validly existing as a
                 corporation in good standing under the laws of its
                 jurisdiction of incorporation and has the corporate power and
                 authority required to carry on its business as it is currently
                 being conducted and to own, lease and operate its properties;

                          (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;

                          (iii)   all of the outstanding shares of capital
                 stock of, or other ownership interests in, each of the
                 Company's subsidiaries have been duly and validly authorized
                 and issued and are fully paid and non-assessable, and are
                 owned by the Company, free and clear of any security interest,
                 claim, lien, encumbrance or adverse interest of any nature
                 (other than liens created under the Credit Facility);

                          (iv)    all the outstanding shares of Common Stock
                 have been duly authorized and validly issued and are fully
                 paid, non-assessable and not subject to any statutory
                 preemptive rights or, to the knowledge of such counsel, any
                 other similar rights;

<PAGE>   16
                          (v)      neither the Company nor any of its Material 
                 Subsidiaries is in violation of its respective charter or
                 by-laws and, to the best of such counsel's knowledge after due
                 inquiry, neither the Company nor any of its Material
                 Subsidiaries is 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 Material
                 Subsidiaries is a party or by which it or any of its
                 subsidiaries or their respective properties are bound;

                          (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;

                          (vii)   to such counsel's knowledge there are no
                 legal or governmental proceedings pending or threatened to
                 which the Company or any of its subsidiaries is a party or to
                 which any of their respective properties are subject which is
                 required to be described in the Registration Statement or the
                 Prospectus and is not so described, or of any contract or
                 other document which is required to be described in the
                 Registration Statement or the Prospectus or is required to be
                 filed as an exhibit to the Registration Statement which is not
                 described or filed as required; such counsel does not have any
                 reason to believe that the description of litigation in the
                 Prospectus is not accurate and complete in all material
                 respects;

                          (viii)  to such counsel's knowledge, except as
                 described in the Prospectus, neither the Company nor any of
                 its subsidiaries has violated any 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;

                          (ix)    to such counsel's knowledge, 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 in the manner described in the Prospectus 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; to such counsel's knowledge, 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,





                                      -16-

                 revocation or termination thereof or results in any other
                 material impairment of the rights of the holder of any such
                 permit, subject in each case to such qualification as may be
                 set forth in the Prospectus; and, except as described in the
                 Prospectus, such permits contain no restrictions that are
                 materially burdensome to the Company or any of its
                 subsidiaries;

                          (x)     to such counsel's knowledge, 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
                 as a result of filing the Registration Statement, which have
                 not been waived;

                          (xi)    such counsel believes that (except for
                 financial statements, financial and statistical information
                 contained therein, as aforesaid and except for that part of
                 the Registration Statement that constitutes the Form T-1) the
                 Registration Statement and the prospectus included therein at
                 the time the Registration Statement became effective did not
                 contain any untrue statement of a material fact or omit to
                 state a material fact required to be stated therein or
                 necessary to make the statements therein not misleading, and
                 that the Prospectus, as amended or supplemented, if applicable
                 (except for financial statements, and financial and
                 statistical information, as aforesaid) does not contain any
                 untrue statement of a material fact or omit to state a
                 material fact necessary in order to make the statements
                 therein, in the light of the circumstances under which they
                 were made, not misleading;

                          (xii)   all descriptions in the Prospectus of
                 statutes, regulations or legal or governmental proceedings in
                 all material respects are accurate and fairly present the
                 information required to be shown;

                 The opinion of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P.
         referred to in subsection (d) above shall contain a statement that
         such counsel believes that (except for financial statements and
         financial and statistical information contained therein, as aforesaid
         and except for that part of the Registration Statement that
         constitutes the Form T-1), the Registration Statement and the
         prospectus included therein at the time the Registration Statement
         became effective did not contain any untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, and that the
         Prospectus, as amended or supplemented, if applicable (except for
         financial statements and financial and statistical information, as
         aforesaid) does not contain any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading.  Liddell, Sapp, Zivley, Hill & LaBoon,
         L.L.P. in giving its opinions with respect to the matters covered by
         clauses (d)(ix) and (e)(xi) may state that its opinions and beliefs
         are based upon its participation in the preparation of the
         Registration Statement and Prospectus and any amendments or
         supplements thereto and review and discussion of the contents thereof,
         but are without independent check or verification except as specified.

                 In giving the opinions described in clause (d) and (e) above,

         dated the Closing Date, of McDermott, Will & Emery, counsel for the 
         Underwriters, in form and substance satisfactory to you.

                 (g)      You shall have received a letter on and as of the
         Closing Date, in form and substance satisfactory to you, from each of
         Coopers & Lybrand L.L.P., Coopers & Lybrand Chartered Accountants and
         Ernst & Young LLP, independent public accountants, with respect to the
         financial statements and certain financial information contained in

         form and substance of the letter delivered to you by Coopers & Lybrand
         LLP, Coopers & Lybrand Chartered Accountants and Ernst & Young LLP, on
         the date of this Agreement.

                 (h)      The Company shall not have failed at or prior to the
         Closing Date to perform or comply with any of the agreements herein
         contained and required to be performed or complied with by the Company
         at or prior to the Closing Date.

                 (i)      The transactions contemplated by the Underwriting
         Agreement dated of even date herewith between you and the Company with
         respect to $300,000,000 principal amount of 7% Senior Notes due 2004
         of the Company (the "2004 Notes Underwriting Agreement") shall be
         consummated simultaneously with the transactions contemplated hereby.

                 (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-
<PAGE>   19
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.

substantially similar tenor signed by such Holders in person or by an agent

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
<PAGE>   14
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.

SECTION 107. Language of Notices, Etc.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of
the country of publication.

SECTION 108. Conflict with Trust Indenture Act.

         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.

SECTION 109. Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 110. Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

SECTION 111. Separability Clause.

         In case any provision in this Indenture or the Securities or coupons
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

SECTION 112. Benefits of Indenture.

         Nothing in this Indenture or the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, their
successors hereunder and the Holders of Securities and coupons, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

SECTION 113. Governing Law.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York.

SECTION 114. Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities or coupons other than a provision in the Securities of any series
which specifically states that such provision shall apply in lieu of this
Section) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

                                  ARTICLE TWO
                                 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 202. Form of Trustee's Certificate of Authentication.

         The Trustee's certificate of authentication shall be in substantially
the following form:

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


                                     ----------------------------------------
                                                    as Trustee

                                     By: 
                                        -------------------------------------
                                                Authorized Signatory."


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
<PAGE>   18
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.

SECTION 204. Form of Legend for Book-Entry Securities.

         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."

                                 ARTICLE THREE
                                 THE SECURITIES

         The aggregate principal amount of Securities which may be

set forth, or determined in the manner provided, in an Officers' Certificate,
or established in one or more indentures supplemental hereto, prior to the
issuance of Securities of any series:

                 (1) the title of the Securities of the series (which shall
         distinguish the Securities of the series from all other Securities);

                 (2) any limit upon the aggregate principal amount of the
         Securities of the series which may be authenticated and delivered
         under this Indenture (except for Securities authenticated and
         delivered upon registration of transfer of, or in exchange for, or in
         lieu of, other Securities of the series pursuant to Section 304, 305,
         306, 906 or 1107 and except for any Securities which, pursuant to
         Section 303, are deemed never to have been authenticated and delivered
         hereunder);

                 (3) whether Securities of the series are to be issuable as
         Registered Securities, Bearer Securities or both, whether any
         Securities of the series are to be issuable initially in temporary
         global form and whether any Securities of the series are to be
         issuable in permanent global form with or without coupons and, if so,
         whether

         may exchange such interests for Securities of such series and of like

         under which any such exchanges may occur, if other than in the manner
         provided in Section 305;

         the close of business on the Regular Record Date for such interest,
         the manner in which, or the Person to whom, any interest on any Bearer
         Security of the series shall be payable, if otherwise than upon
         presentation and surrender of the coupons appertaining thereto as they
         severally mature and the extent to which, or the manner in which, any
         interest payable on a temporary global Security on an Interest Payment
         Date will be paid if other than in the manner provided in Section 304;

                 (5) the date or dates on which the principal of the Securities
         of the series is payable;

                 (6) the rate or rates at which the Securities of the series
         shall bear interest, if any, or the method by which such rate shall be
         determined, the date or dates from which any such interest shall
         accrue, the Interest Payment Dates on which any such interest shall be
         payable, and the Regular Record Date for any interest payable on any

         Section 1002, the principal of and any premium and interest on
         Securities of the series shall be payable, any Registered Securities
         of the series may be surrendered for registration of transfer or
         exchange;

                 (8) the right, if any, of the Company to redeem Securities of
         the series, in whole or in part, at its option and the period or

         conditions upon which Securities of the series may be so redeemed;

                 (9) the obligation, if any, of the Company to redeem,
         purchase, or repay Securities of the series pursuant to any mandatory
         redemption, sinking fund or analogous provisions or at the option of a

<PAGE>   20
                 (14) if the principal of and any premium or interest on the
         Securities of the series are to be payable, at the election of the
         Company or a Holder thereof, in a currency or currencies, including

         election is to be made;

                 (15) the applicability, if any, of Section 1008 or Section
         1009 to the Securities of such series;

         inconsistent with the provisions of this Indenture except as permitted
         by Section 901(5)).

         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
<PAGE>   21
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
<PAGE>   22
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
<PAGE>   23
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
<PAGE>   24
         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
<PAGE>   25
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
<PAGE>   26
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.

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
<PAGE>   28
(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.

exchange of Securities herein expressly provided for, and any right to receive
additional amounts, as provided in Section 1004), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

                 (A) all Securities theretofore authenticated and delivered and
         all coupons, if any, appertaining thereto (other than (i) coupons
         appertaining to Bearer Securities surrendered for exchange for

         surrender is not required or has been waived as provided in Section

         trust or segregated and held in trust by the Company and thereafter
         repaid to the Company or discharged from such trust, as provided in
         Section 1003) have been delivered to the Trustee for cancellation; or

                 (B) all such Securities and, in the case of (i) or (ii) below,
         any coupons appertaining thereto not theretofore delivered to the
         Trustee for cancellation

                          (i) have become due and payable, or

                          (ii) will become due and payable at their Stated 
                 Maturity within one year, or

                 of notice of redemption by the Trustee in the name, and at the
                 expense, of the Company;

         and the Company, in the case of (i), (ii) or (iii) above, has
         deposited or caused to be deposited with the Trustee as trust funds in
         trust for the purpose an amount sufficient to pay and discharge the
         entire indebtedness on such Securities and coupons not theretofore
         delivered to the Trustee for cancellation, for principal (and premium,
         if any) and any interest to the date of such deposit (in the case of
         Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

         (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to clause (1)(B) of this Section,
the obligations of the Trustee under Section 402 and the last paragraph of
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.

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

         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
<PAGE>   31
                 (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
<PAGE>   32
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
<PAGE>   33
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
<PAGE>   34
                 (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
<PAGE>   35
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.

SECTION 601. Certain Duties and Responsibilities.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.

SECTION 602. Notice of Defaults.

         If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice
of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified
in Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

SECTION 603. Certain Rights of Trustee.

         Subject to the provisions of Section 601:

                 (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                 (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order
         and any resolution of the Board of Directors shall be sufficiently
         evidenced by a Board Resolution;

                 (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                 (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

                 (5) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;





                                       30
<PAGE>   37
                 (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.

SECTION 604. Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) and in any coupons shall be taken as
the statements of the Company, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons. 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 606. Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

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
<PAGE>   38
         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
<PAGE>   39
         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
<PAGE>   40
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
<PAGE>   41
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
<PAGE>   42
Affiliate of the Company) having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

is furnished;

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.

SECTION 702. Preservation of Information:  Communications to Holders.

         Without the consent of any Holders of Securities or coupons, the

                 (2) to add to the covenants of the Company for the benefit of
         the Holders of all or any series of Securities (and if such covenants
         are to be for the benefit of less than all series of Securities,
         stating that such covenants are expressly being included solely for
         the benefit of such series) or to surrender any right or power herein
         conferred upon the Company; or

         neither (i) apply to any Security of any series created prior to the
         execution of such supplemental indenture and entitled to the benefit
         of such provision nor (ii) modify the rights of the Holder of any such
         Security with respect to such provision or (B) shall become effective
         only when there is no such Security Outstanding; or

                 (6) to secure the Securities pursuant to the requirements of
         Section 1006 or otherwise; or

                 (7) to establish the form or terms of Securities of any series

         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611(b); or

                 (9) to cure any ambiguity, to correct or supplement any
         provision herein or in any supplemental indenture which may be
         defective or inconsistent with any other provision herein or in any
         supplemental indenture, or to make any other provisions with respect
         to matters or questions arising under this Indenture; provided, that
         such action shall not adversely affect the interests of the Holders of
         Securities of any series or any related coupons in any material
         respect.

SECTION 902. Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of a majority in principal amount of
the Outstanding Securities of each series affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company, when authorized by a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities of such series and any related coupons under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby,

                 (1) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, any Security, or reduce
         the principal amount thereof or the rate of interest thereon or any
         premium payable upon the redemption thereof, or change the Redemption
         Date thereof, or change any obligation of the Company to pay
         additional amounts pursuant to Section 1004 (except as contemplated by
         Section 801 (1) and permitted by Section 901(1)), or reduce the amount
         of the principal of an Original Issue Discount Security that would be
         due and payable upon a declaration of acceleration of the Maturity
         thereof pursuant to Section 502 or change the coin or currency in
         which any Security or any premium or interest thereon is payable, or
         change any right of redemption, purchase or repayment by the Company
         at the option of the Holder, or impair the right to institute suit for
         the enforcement of any such payment on or after the Stated Maturity
         thereof (or, in the case of redemption, on or after the Redemption
         Date), or

                 (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose

         provisions of this Indenture or certain defaults hereunder and their
         consequences provided for in this Indenture, or reduce the
         requirements of Section 1404 for quorum or voting, or

                 (3) change any obligation of the Company to maintain an office
         or agency in the places and for the purposes specified in Section
         1002, or

                 (4) modify any of the provisions of this Section, Section 513
         or Section 1007 except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby; provided, however, that this clause shall not be
         deemed to require the consent of any Holder of a Security or coupon
         with respect to changes in the references to "the Trustee" and
         concomitant changes in this Section and Section 1007 or the deletion
         of this provision, in accordance with the requirements of Sections
         611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders of Securities under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

SECTION 903. Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to
receive and (subject to Section 601) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter





                                       39
<PAGE>   46
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

SECTION 904. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupons appertaining thereto shall be bound thereby.

SECTION 905. Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 906. Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series and of like
tenor.

                                  ARTICLE TEN
                                   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
<PAGE>   47
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
<PAGE>   48
         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
<PAGE>   49
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.

         Unless established in or pursuant to a Board Resolution and, subject
to Section 303, set forth in or determined in the manner provided, in an
Officers' Certificate, or established in one or more indentures supplemental
hereto, prior to the issuance of Securities of any series, the provisions of
this Section 1008 shall apply to each series of Securities issued under this
Indenture:

         (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, create, incur, assume or suffer to exist, directly or
indirectly, any Indebtedness secured by a Security Interest upon any Principal
Property of the Company or of a Restricted Subsidiary, whether owned as of the
date of this Indenture or hereafter acquired, without making effective
provision (and the Company hereby covenants that in any such case it shall make
or cause to be made effective provision) whereby the Securities of that series
then outstanding and any other Indebtedness of the Company or any Restricted
Subsidiary then entitled thereto shall be secured by such Security Interest
equally and ratably with (or, in the case of the Securities of that series and
if the Company shall so determine, prior to) any and all other Indebtedness of
the Company or any Restricted Subsidiary thereby secured for so long as any
such other Indebtedness of the Company or any Restricted Subsidiary shall be so
secured; provided, that nothing in this Section 1008 shall prevent, restrict or
apply to Indebtedness secured by:

         (1) (a) Any Security Interest upon property or assets which is created
prior to or contemporaneously with, or within 360 days after, (i) in the case
of the acquisition of such property or assets, the completion of such

payment, financing or refinancing, directly or indirectly, of all or any part
of the acquisition cost of such property or assets or the cost of construction,
development or improvement thereof; or (b) any Security Interest upon property
or assets existing at the time of the acquisition thereof, which Security

entirety to the Company or any Restricted Subsidiary or at the time such
corporation becomes a Restricted Subsidiary; or (e) any Security Interest
existing on the property, assets or shares of stock of any successor which
shall have become the Company in accordance with the provisions of Section 801
hereof; provided, in each case, that any such Security Interest described in

property or assets owned by the Company or any Restricted Subsidiary prior to
the event referred to in such clauses; or

         (2) Mechanics', materialmen's, carriers' or other like liens arising
in the ordinary course of business (including construction of facilities) in
respect of obligations which are not due or which are being contested in good
faith; or

         (3) Any Security Interest arising by reason of deposits with, or the
giving of any form of security to, any governmental agency or any body created
or approved by law or governmental regulation, which is required by law or
governmental regulation as a condition to the transaction of any business or
the exercise of any privilege, franchise or license (including, without
limitation, any Security Interest arising by reason of one or more letters of
credit in connection with any international waste management contract to be
performed by the Company or any of its Subsidiaries or their respective
affiliates); or

         (4) Security Interests for taxes, assessments or governmental charges
or levies not yet delinquent or Security Interests for taxes, assessments or
governmental charges or levies already delinquent but the validity of which is
being contested in good faith; or

         (5) Security Interests (including judgment liens) arising in
connection with legal proceedings so long as such proceedings are being
contested in good faith and, in the case of judgment liens, execution thereon
is stayed; or

         (6) Landlords' liens on fixtures located on premises leased by the
Company or any Restricted Subsidiary in the ordinary course of business; or

         (7) Any Security Interest in favor of any governmental authority in
connection with the financing of the cost of construction or acquisition of

<PAGE>   51
entered into by the Company or by any Restricted Subsidiary, provided that such
program is on terms comparable for similar transactions, or any document

receivables in respect of which such program is created or exists and the
proceeds thereof; or

         (12) Any extension, renewal or refunding (or successive extensions,
renewals or refundings) in whole or in part of any Indebtedness secured by any
Security Interest referred to in the foregoing clauses (1) through (11),
inclusive, provided that the Security Interest securing such Indebtedness shall
be limited to the property or assets which, immediately prior to such
extension, renewal or refunding, secured such Indebtedness and additions to
such property or assets.

         Notwithstanding the foregoing provisions of this Section 1008(a), the
Company or any of its Restricted Subsidiaries may create, incur, assume or
suffer to exist any Indebtedness secured by a Security Interest without so
securing the Securities of that series if, at the time such Security Interest
becomes a Security Interest upon any Principal Property of the Company or such
Restricted Subsidiary and after giving effect thereto, the aggregate
outstanding principal amount of all Indebtedness of the Company and its
Restricted Subsidiaries secured by Security Interests permitted by this
sentence (excluding Indebtedness secured by a Security Interest existing as of
the date of this Indenture, but including the Attributable Debt in respect of
Sale and Leaseback Transactions (as defined in Section 1009), other than Sale
and Leaseback Transactions which, if the Attributable Debt in respect thereof
had been Indebtedness secured by a Security Interest, would have been permitted
by clause (1)(a) above, other Sale and Leaseback Transactions the proceeds of
which have been applied or committed to be applied in accordance with Section
1009(b) or Section 1009(c) and other than Sale and Leaseback Transactions

time under this Indenture compounded semi-annually, in either case, of the
obligation of a lessee for rental payments during the remaining term of any
lease (including any period for which such lease has been extended or may, at
the option of the lessor, be extended); the net amount of rent required to be
paid for any such period shall be the total amount of the rent payable by the
lessee with respect to such period but may exclude amounts required to be paid
on account of maintenance and repairs, insurance, taxes, assessments, water
rates and similar charges; and, in the case of any lease which is terminable by
the lessee upon the payment of a penalty, such net amount shall also include
the amount of such penalty, but no rent shall be considered as required to be

debt) and (ii) the value (net of any applicable reserves) of all intangible
assets such as excess of cost over net assets of acquired businesses, customer
lists, covenants not to compete, licenses, and permits, all as set forth on the

the Company's most recently completed fiscal quarter, prepared in accordance
with United States generally accepted accounting principles.

obligation or other liability of any other Person (other than by endorsements
of instruments in the course of collection), or guarantees the payment of
dividends or other distributions upon the shares of any other Person. The
amount of the obligor's obligation under any Guaranty shall (subject to any
limitation set forth therein) be deemed





                                       45
<PAGE>   52
to be the amount of such other Person's debt, obligation or other liability or
the amount of such dividends or other distributions guaranteed.

         The term "Indebtedness" of any Person shall mean

         (a) all obligations of such Person for borrowed money (including,
without limitation, all notes payable and drafts accepted representing

         thereon) secured by a Security Interest in property owned or being
         purchased by such Person (including, without limitation, indebtedness
         arising under conditional sales or other title retention agreements)
         whether or not such indebtedness shall have been assumed by such
         Person, and

                 (ii) all Guaranties of such Person.

not of material importance to the total business conducted, or assets owned, by
the Company and its Subsidiaries as an entirety, or (b) any portion of such
plant or facility which the Board of Directors determines in good faith not to
be of material importance to the use or operation thereof.

designate as a Restricted Subsidiary in an Officers' Certificate delivered to
the Trustee.

         The term "Security Instrument" shall mean any security agreement,

personal property or fixture which secures payment or performance of an
obligation and shall include any mortgage, lien, encumbrance, charge or other
security interest of any kind, whether arising under a Security Instrument or
as a matter of law, judicial process or otherwise.

         (b) If, upon any consolidation or merger of any Restricted Subsidiary
with or into any other corporation, or upon any consolidation or merger of any
other corporation with or into the Company or any Restricted Subsidiary or upon
any sale or conveyance of the Principal Property of any Restricted Subsidiary
as an entirety or substantially as an entirety to any other Person, or upon any
acquisition by the Company or any Restricted Subsidiary by purchase or
otherwise of all or any part of the Principal Property of any other Person, any
Principal Property theretofore owned by





                                       46
<PAGE>   53
the Company or such Restricted Subsidiary would thereupon become subject to any
Security Interest not permitted by the terms of this Section 1008, the Company,
prior to such consolidation, merger, sale or conveyance, or acquisition, will,
or will cause such Restricted Subsidiary to, secure payment of the principal of
and interest, if any, on the Securities of that series (equally and ratably
with or prior to any other Indebtedness of the Company or such Restricted
Subsidiary then entitled thereto) by a direct lien on all such Principal
Property prior to all liens other than any liens theretofore existing thereon
by supplemental indenture hereto or otherwise.

         (c) If at any time the Company or any Restricted Subsidiary shall
create, incur, assume or suffer to exist any Indebtedness secured by any
Security Interest not permitted by this Section 1008, to which the covenant in
the first paragraph of Section 1008(a) or Section 1008(b) is applicable, the
Company will promptly deliver to the Trustee

                 (1) an Officers' Certificate stating that the covenant of the
         Company contained in the first paragraph of Section 1008(a) or Section
         1008(b) has been complied with; and

                 (2) an Opinion of Counsel to the effect that such covenant has
         been complied with, and that any instruments executed by the Company
         in the performance of such covenant comply with the requirements of
         such covenant.

         (d) In the event that the Company shall hereafter secure the
Securities equally and ratably with or prior to any other obligation or
indebtedness pursuant to the provisions of this Section 1008, the Trustee is
hereby authorized to enter into an indenture or agreement supplemental hereto
and to take such action, if any, as it may deem advisable to enable it to
enforce effectively the rights of the Holders of the Securities so secured,
equally and ratably with or prior to such other obligations or indebtedness.

SECTION 1009. Limitations On Sale And Leaseback Transactions.

         Unless established in or pursuant to a Board Resolution and, subject
to Section 303, set forth in or determined in the manner provided, in an
Officers' Certificate, or established in one or more indentures supplemental
hereto, prior to the issuance of Securities of any series, the provisions of
this Section 1009 shall apply to each series of Securities issued under this
Indenture:

         The Company will not, and will not permit any Restricted Subsidiary
to, enter into any arrangement with any Person (other than with any Restricted
Subsidiary) providing for the leasing to the Company or any Restricted
Subsidiary of any Principal Property owned or hereafter acquired by the Company
or such Restricted Subsidiary (except for temporary leases for a term,
including any renewal thereof, of not more than three years and except for
leases between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries), which Principal Property has been or is to be sold or
transferred by the Company or such Restricted Subsidiary to such person (herein
referred to as a "Sale and Leaseback Transaction") unless (a) the Company or
such Restricted Subsidiary would be entitled, pursuant to the provisions of (1)
clause (1)(a) of Section 1008(a) or (2) the second paragraph of Section
1008(a), to incur Indebtedness secured by a Security Interest on the property
to be leased without equally and ratably securing the Securities of that
series, or (b) the Company shall, and in any such case the Company covenants
that it will, within 180 days after the effective date of any such arrangement,
apply an amount equal to the fair value (as determined by the Board of
Directors) of such property to the redemption of Securities that, by their
terms, are subject to redemption, or to the purchase and retirement of
Securities, or to the payment or other retirement of funded debt for money
borrowed, incurred or assumed by the Company which ranks senior to or pari
passu with the Securities of that series or of funded debt for money borrowed,
incurred or assumed by any Restricted Subsidiary (other than, in either case,
funded debt owned by the Company or any Restricted Subsidiary), or (c) the
Company shall within 180 days after entering into the Sale and Leaseback
Transaction, enter into a bona fide commitment or commitments to expend for the
acquisition or capital improvement of a Principal Property an amount at least
equal to the fair value (as determined by the Board of Directors) of such
property. Funded Debt means any Indebtedness which by its terms matures at or
is extendable or





                                       47
<PAGE>   54
renewable at the sole option of the obligor without requiring the consent of
the obligee to a date more than twelve months after the date of the creation of
such Indebtedness.

         Notwithstanding the foregoing, the Company may, and may permit any
Restricted Subsidiary to, effect any Sale and Leaseback Transaction that is not
acceptable pursuant to clauses (a) through (c), inclusive, of this Section
1009, provided that the Attributable Debt associated with such Sale and
Leaseback Transaction, together with the aggregate principal amount of
outstanding debt secured by Security Interests upon Principal Property not
acceptable pursuant to clauses (1) through (12) of Section 1008, inclusive, do
not exceed 15% of Consolidated Net Tangible Assets.

                                 ARTICLE ELEVEN
                            REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any
series) in accordance with this Article.

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. In the case of any redemption of Securities (i)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture, or (ii) pursuant to an
election of the Company which is subject to a condition specified in the terms
of such Securities, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction or condition.

SECTION 1103. Selection of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series of a specified tenor are to be
redeemed) the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Company or the Trustee, from
the Outstanding Securities of such series not previously called for redemption,
by such method as the Company or the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of portions (equal to
the minimum authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Registered Securities of
such series of a denomination larger than the minimum authorized denomination
for Securities of that series or of the principal amount of global Securities
of such series. If less than all of the Securities of such series and of a
specified tenor are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 45 days prior to the Redemption Date by the
Company or the Trustee, from the Outstanding Securities of such series and
specified tenor not previously called for redemption in accordance with the
preceding sentence.

         The Company or the Trustee, as the case may be, shall promptly notify
the other in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.





                                       48
<PAGE>   55
SECTION 1104. Notice of Redemption.

         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
<PAGE>   56
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.

                                 ARTICLE TWELVE
                                 SINKING FUNDS

SECTION 1201. Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(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

<PAGE>   57
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

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

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. Company's Option to Effect Defeasance or Covenant Defeasance.

         The Company may at its option by Board Resolution, at any time, elect
to have either Section 1302 or Section 1303 applied to the Outstanding
Securities of any series upon compliance with the conditions set forth below in
this Article Thirteen.

SECTION 1302. Defeasance and Discharge.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series
on the date the conditions set forth below are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
the Outstanding Securities of such series and to have satisfied all its other
obligations under the Securities of such series and this Indenture insofar as
the Securities of such series are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder:  (A) the rights of Holders of the Securities of such series to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on the Securities of such series when such payments are

Sections 304, 305, 306, 1002, 1003 and 1004, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Thirteen.
Subject to compliance with this Article Thirteen, the Company may exercise its
option under this Section 1302 notwithstanding the prior exercise of its option
under Section 1303.

SECTION 1303. Covenant Defeasance.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, (i) the Company shall be released from its
obligations with respect to the Securities of such series under Sections 801
and 1005, and (ii) the occurrence of an event specified in Sections 501(3) or
(4) shall not be deemed to be an Event of Default on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant defeasance"),
but the remainder of this Indenture and such Securities shall be unaffected
thereby. For this purpose, such covenant defeasance means that





                                       51
<PAGE>   58
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such Section or clause
whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or clause or by reason of any reference in any such Section or
clause to any other provision herein or in any such Section or clause to any
other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to application of either Section
1302 or Section 1303 to the then Outstanding Securities of any series:

                 (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 609 who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds
         in trust for the purpose of making the following payments specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of the Securities of such series, (A) money in an amount, or
         (B) U.S. Government Obligations which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment, money in an amount, or (C) a combination thereof, sufficient,
         in the opinion of a nationally recognized firm of independent public
         accountants expressed in a written certification thereof delivered to
         the Trustee, to pay and discharge, and which shall be applied by the
         Trustee (or other qualifying trustee) to pay and discharge, the
         principal of (and premium, if any) and each installment of interest on
         the Securities and any coupons pertaining thereto on the Stated
         Maturity of such principal (and premium, if any) or installment of
         interest in accordance with the terms of this Indenture and of the
         Securities of such series. For this purpose, "U.S. Government
         Obligations" means securities that are (x) direct obligations of the
         United States of America for the payment of which its full faith and
         credit is pledged or (y) obligations of a Person controlled or
         supervised by and acting as an agency or instrumentality of the United
         States of America the payment of which is unconditionally guaranteed
         as a full faith and credit obligation by the United States of America,
         which, in either case, are not callable or redeemable at the option of
         the issuer thereof, and shall also include a depository receipt issued
         by a bank (as defined in Section 3(a)(2) of the Securities Act of
         1933, as custodian with respect to any such U.S. Government Obligation
         or a specific payment of principal of or interest on any such U.S.
         Government Obligation held by such custodian for the account of the
         holder of such depository receipt, provided that (except as required
         by law) such custodian is not authorized to make any deduction from
         the amount payable to the holder of such depository receipt from any
         amount received by the custodian in respect of the U.S. Government
         Obligation or the specific payment of principal of or interest on the
         U.S. Government Obligation evidenced by such depository receipt.

                 (2) In the case of an election under Section 1302, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (x) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (y) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to the effect that, and based thereon such opinion
         shall confirm that, the Holders of the Outstanding Securities of such
         series will not recognize income, gain or loss for Federal income tax
         purposes as a result of such deposit, defeasance and discharge and
         will be subject to Federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such
         deposit, defeasance and discharge had not occurred.

                 (3) In the case of an election under Section 1303, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the
         effect that the Holders of the Outstanding Securities of such series
         will not recognize gain or loss for Federal income tax purposes as a
         result of such deposit and covenant defeasance and will be subject to
         Federal income tax on the same amount, in the same manner and at the
         same times as would have been the case if such deposit and covenant
         defeasance had not occurred.

<PAGE>   59
                 (4) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit or, insofar as subsections 501(5) and (6) are
         concerned, at any time during the period ending on the 121st day after
         the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until the expiration of such period).

                 (5) Such defeasance or covenant defeasance shall not cause the
         Trustee to have a conflicting interest within the meaning of the Trust
         Indenture Act with respect to any securities of the Company.

                 (6) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, any other
         agreement or instrument to which the Company is a party or by which it
         is bound.

                 (7) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the defeasance
         under Section 1302 or the covenant defeasance under Section 1303 (as
         the case may be) have been complied with.

                 (8) Such defeasance or covenant defeasance shall not result in
         the trust arising from such deposit constituting an investment company
         as defined in the Investment Company Act of 1940, or such trust shall
         be qualified under such Act or exempt from regulation thereunder.

SECTION 1305. Deposited Money and U.S. Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee -- collectively, for
purposes of this Section 1305, the "Trustee") pursuant to Section 1304 in
respect of the Securities of such series shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities of such
series 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 Holders of the Securities of such series, of all
sums due and to become due thereon in respect of principal (and premium, if
any) and interest, but such money need not be segregated from other funds
except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Securities.

         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.

SECTION 1306. Reinstatement.

         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
<PAGE>   60
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities of such series to receive such payment from
the money held by the Trustee or the Paying Agent.

                                ARTICLE FOURTEEN
                       MEETINGS OF HOLDERS OF SECURITIES

authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such
series.

SECTION 1402. Call, Notice and Place of Meetings.

         (a) The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1401, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, or in London as the Trustee shall determine. Notice of every meeting of
Holders of Securities of any series, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such
meeting, shall be given, in the manner provided in Section 106, not less than
21 nor more than 120 days prior to the date fixed for the meeting.

         (b) In case at any time the Company, pursuant to a Board Resolution,

Securities of any series shall have requested the Trustee to call a meeting of
the Holders of Securities of such series for any purpose specified in Section
1401, by written request setting forth in reasonable detail the action proposed
to be taken at the meeting, and the Trustee shall not have made the first
publication of the notice of such meeting within 21 days after receipt of such
request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series
in the amount above specified, as the case may be, may determine the time and
the place in the Borough of Manhattan, The City of New York, or in London for
such meeting and may call such meeting for such purposes by giving notice

SECTION 1404. Quorum; Action.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes of the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10

is scheduled to be reconvened. Notice of the reconvening of





                                       54
<PAGE>   61
an adjourned meeting shall state expressly the percentage, as provided above,
of the principal amount of the Outstanding Securities of such series which
shall constitute a quorum.

         Except as limited by Section 512 or the proviso to the first paragraph
of Section 902, any resolution presented to a meeting (or adjourned meeting
duly reconvened at which a quorum is present as aforesaid) may be adopted by
the affirmative vote of the Holders of a majority in principal amount of the
Outstanding Securities of that series; provided, however, that, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action which this Indenture expressly provides may be made,
given or taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of a series may be
adopted at a meeting (or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid) by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of that
series.

         To the extent consistent with the terms of this Indenture, any
resolution passed or decision taken at any meeting of Holders of Securities of
any series duly held in accordance with this Section shall be binding on all
the Holders of Securities of such series and the related coupons, whether or
not present or represented at the meeting.

SECTION 1405. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

         (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section
104 and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the Person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations
may provide that written instruments appointing proxies, regular on their face,
may be presumed valid and genuine without the proof specified in Section 104 or
other proof.

         (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1402(b), in
which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

         (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1402 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 1406. Counting Votes and Recording Action of Meetings.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives





                                       55
<PAGE>   62
by proxy and the principal amounts and serial numbers of the Outstanding
Securities of such series held or represented by them. The permanent chairman
of the meeting shall appoint two inspectors of votes who shall count all votes
cast at the meeting for or against any resolution and who shall make and file
with the secretary of the meeting their verified written reports in duplicate
of all votes cast at the meeting. A record, at least in duplicate, of the
proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 1402 and, if applicable, Section 1404.
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to
the Company, and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so
signed and verified shall be conclusive evidence of the matters therein stated.

financial institution described in clause (iii) above (whether or not also
described in clause (i) or (ii)), this is to further certify that such
financial institution has not acquired the Securities for purposes of resale
directly or indirectly to a United States person or to a person within the
United States or its possessions.

         If the Securities are of the category contemplated in Section
230.903(c)(3) of Regulation S under the Securities Act of 1933, as amended (the
"Act"), then this is also to certify that, except as set forth below (i) in the
case of debt securities, the Securities are beneficially owned by (a) non-U.S.
person(s) or (b) U.S. person(s) who purchased the Securities in transactions
which did not require registration under the Act; or (ii) in the case of equity
securities, the Securities are owned by (x) non-U.S. person(s) (and such
person(s) are not acquiring the Securities for the account or benefit of U.S.
person(s)), or (y) U.S. person(s) who purchased the Securities in a transaction
which did not require registration under the Act. If this certification is
being delivered in connection with the exercise of warrants pursuant to Section
230.902(m) of Regulation S under the Act, then this is further to certify that,
except as set forth below, the Securities are being exercised by and on behalf
of non-U.S. person(s). As used in this paragraph, the term "U.S. person" has
the meaning given to it by Regulation S under the Act.

         As used herein, "United States" or "U.S." means the United States of
America (including the States and District of Columbia); and its "possessions"
include Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake Island
and the Northern Mariana Islands.

         We undertake to advise you promptly by tested telex on or prior to the
date on which you intend to submit your certification relating to the
Securities held by you for our account in accordance with your Operating
Procedures if any applicable statement herein is not correct on such date, and
in the absence of any such notification it may be assumed that this
certification applies as of such date.

         This certification excepts and does not relate to $_________ of such
interest in the above Securities in respect of which we are not able to certify
and as to which we understand exchange and delivery of definitive Securities
(or, if relevant, exercise of any rights or collection of any interest) cannot
be made until we do so certify.

                            USA WASTE SERVICES, INC.

                            7% SENIOR NOTE DUE 2004


         This Book-Entry Security is one of a duly authorized issue of
Securities or other evidences of indebtedness of the Company (the "Securities")
of the series hereinafter specified, all issued or to be issued under and
pursuant to the Indenture, to which Indenture reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities. The Securities may be issued in one or more series, which different
series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different sinking, purchase or analogous funds (if any) and may otherwise
vary as provided in the Indenture. 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.

3.       Paying Agent and Registrar.

         Initially, Texas Commerce Bank National Association (the "Trustee")
will act as Paying Agent and Registrar. The Company may change any Paying
Agent, Registrar or co-Registrar at any time upon notice to the Trustee and the
Holders. The Company or any of its Subsidiaries may, subject to certain
exceptions, act as Paying Agent, Registrar or co-Registrar.

4.       Indenture.

         This Security is one of a duly authorized issue of Securities of the
Company issued and to be issued in one or more series under an Indenture, dated
as of September 10, 1997 (the "Indenture"), between the Company and the
Trustee.


                                       3

<PAGE>   4



Capitalized terms herein are used as defined in the Indenture unless otherwise
defined herein. The terms of the Securities include those stated in the
Indenture, all indentures supplemental thereto, those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended, as in
effect on the date of the Indenture, and those terms stated in the Resolutions
of the Pricing Committee of the Board of Directors of the Company dated
September 10, 1997 (the "Resolutions"). The Securities are subject to all such
terms, and Holders of Securities are referred to the Indenture, all indentures
supplemental thereto, said Act and said Resolutions for a statement of them.
The Securities of this series are general unsecured obligations of the Company
limited in aggregate principal amount to $300,000,000.

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

<PAGE>   5



         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.

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.

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

                         REVERSE OF BOOK-ENTRY SECURITY

                            USA WASTE SERVICES, INC.

                           7 1/8% SENIOR NOTE DUE 2007


         This Book-Entry Security is one of a duly authorized issue of
Securities or other evidences of indebtedness of the Company (the "Securities")
of the series hereinafter specified, all issued or to be issued under and
pursuant to the Indenture, to which Indenture reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities. The Securities may be issued in one or more series, which different
series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject
to different sinking, purchase or analogous funds (if any) and may otherwise
vary as provided in the Indenture. This Security is one of a series designated
as the 7 1/8% Senior Notes due 2007 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 1/8% 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 1/8% 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.

3.       Paying Agent and Registrar.

         Initially, Texas Commerce Bank National Association (the "Trustee")
will act as Paying Agent and Registrar. The Company may change any Paying
Agent, Registrar or co-Registrar at any time upon notice to the Trustee and the
Holders. The Company or any of its Subsidiaries may, subject to certain
exceptions, act as Paying Agent, Registrar or co-Registrar.

4.       Indenture.

         This Security is one of a duly authorized issue of Securities of the
Company issued and to be issued in one or more series under an Indenture, dated
as of September 10, 1997 (the "Indenture"), between the Company and the
Trustee. Capitalized terms herein are used as defined in the Indenture unless
otherwise defined herein. The terms of the Securities include those stated in
the Indenture, all indentures supplemental thereto, those made part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended, as in
effect on the date of the Indenture, and those terms stated in the Resolutions
of the Pricing Committee of the Board of Directors of the Company dated
September 10, 1997 (the "Resolutions"). The Securities are subject to all such
terms, and Holders of Securities are referred to the Indenture, all indentures
supplemental thereto, said Act and said Resolutions for a statement of them.
The Securities of this series are general unsecured obligations of the Company
limited in aggregate principal amount to $300,000,000.

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 Deutsche Morgan Grenfell Inc. 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.

         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.

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.

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, 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.

11.      Authentication.

         This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on the other side of this
Security.

12.      Abbreviations and Defined Terms.

         Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as: TEN COM (=tenant in common), TEN ENT
(=tenants by the entireties), JT TEN (=joint tenants with right of survivorship
and not as tenants in common), CUST (=Custodian), and U/G/M/A (=Uniform Gifts
to Minors Act).

13.      CUSIP Numbers.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Note Identification Procedures, the Company will cause CUSIP numbers to be
printed on the Securities as a convenience to the Holders of the Securities. 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.

absolute and unconditional, to pay the principal of and interest on this
Security in the manner, at the respective times, at the rate and in the coin or
currency herein prescribed.

15.      No Recourse.

contained in the Indenture or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any incorporator, past, present or
future stockholder, officer or director, as such of the Company or of any

the laws of the State of New York.
