Dear Sirs:

         USA Waste Services, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell $350,000,000 principal amount of its 6-1/2% Senior
Notes due 2002 (the "Securities"), to the several underwriters named in
Schedule I hereto (the "Underwriters").  The Securities are to be issued
pursuant to the provisions of an indenture (the "Senior Indenture") to be dated
as of September 10, 1997 between the Company and Texas Commerce Bank, National
Association, as trustee (the "Trustee").  The terms of the Securities are set
forth in resolutions of the Pricing Committee of the Board of Directors of the
Company dated as of the date hereof (the "Resolutions").

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





<PAGE>   2
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 though not specifically stated, any document filed under the
Securities 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 99.963% of the principal amount thereof (the "Purchase
Price") plus accrued interest thereon, if any, from December 17, 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 this Agreement 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.

<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 Rule 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
         Rule 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





                                      -3-

         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.

                 (e)      Annex I is an accurate and complete list of all
         subsidiaries of the Company (the "Material Subsidiaries") which
         accounted for more than $52.5 million of revenues during the nine
         months ended September 30, 1997 or which, as of September 30, 1997,

         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 of 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





                                      -6-

         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 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)      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.

                 (m)      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.

                 (n)      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





                                      -7-
<PAGE>   8
         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.

                 (o)      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
         ("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.

                 (p)      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.

                 (q)      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.

                 (r)      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.

         aggregate could not reasonably be expected to have a material adverse
         effect on the Company and its subsidiaries, taken as a whole.

                 (aa)     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)

         with the offering and sale of the Securities.

Any certificate or other document signed by any officer or authorized

Company to each Underwriter as to the matters 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

         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 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





                                      -11-
<PAGE>   12
         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
         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 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:

         Closing Date.

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

         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

         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 Closing Date you shall have received a certificate dated the

                 business as it is currently being conducted and to own, lease

                 the enforceability thereof may be limited by bankruptcy,

                 generally and (b) rights of acceleration and the availability
                 of equitable remedies may be limited by equitable principles

                 affecting creditors' rights generally and by general

                 the Prospectus and Item 15 of Part II of the Registration
                 Statement, insofar as such statements constitute a summary of

                 the information called for with respect to such legal matters
                 or documents;

                 hereof and thereof and the consummation of the transactions
                 contemplated hereby and thereby will not require any consent,

                 comply as to form in all material respects with the Act;

                 (e)      You shall have received on the Closing Date an

         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

                          (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

                 (other than liens created under the Credit Facility);

                 other similar rights;

                 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,

                 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

                 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

                 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





                                      -16-
<PAGE>   17
                 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.  In
         making such statement, Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P.
         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 Coopers
         & Lybrand L.L.P., 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 Coopers & Lybrand
         L.L.P. 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 $150,000,000 principal amount of 7-1/8% Senior Notes due
         2017 of the Company (the "2017 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





                                      -18-
<PAGE>   19
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 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 $150,000,000 principal amount of its 7-1/8% Senior

         requires the making of any additions to or changes in the Registration
         Statement or the Prospectus in order to make the statements therein

         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

         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 of the outstanding shares of capital stock of the
         Company have been duly authorized and validly issued and are fully

         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

         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 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.

         description thereof contained in the Prospectus.

                 (l)      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.

                 (m)      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.

                 (n)      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





                                      -7-

         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.

                 (o)      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
         ("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.

                 (p)      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.

                 (q)      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.

                 (r)      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.

         complaint pending against the Company or any of its subsidiaries or,
         to the knowledge of the Company, threatened against any of them,

         aggregate could not reasonably be expected to have a material adverse
         effect on the Company and its subsidiaries, taken as a whole.

                 (aa)     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)

         information is given in the Registration Statement and the Prospectus
         and prior to the Closing Date, (i) there has not been and will not

         partnership capital), net worth or results of operations of the
         Company and its subsidiaries, taken as a whole.

                 (dd)     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 matters 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





                                      -10-
<PAGE>   11
         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 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





                                      -11-
<PAGE>   12
         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
         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.

<PAGE>   13
                 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 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

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

                 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

                          (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

                 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);

<PAGE>   16
                          (iv)    all of 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;

                          (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





                                      -16-
<PAGE>   17
                 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.  In making such statement, Liddell, Sapp,
         Zivley, Hill & LaBoon, L.L.P. 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.

         form and substance of the letter delivered to you by Coopers & Lybrand
         L.L.P. 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 $350,000,000 principal amount of 6-1/2% Senior Notes due

                 (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 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.

this Agreement shall be addressed as follows: (a) if to the Company, to USA

                          6 1/2% SENIOR NOTE DUE 2002


         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 6 1/2% Senior Notes due 2002 of the Company, limited in
aggregate principal amount to $350,000,000.

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 6 1/2% 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 6 1/2% per annum.

         The Company will pay interest semi-annually on December 15 and June 15
of each year (each an "Interest Payment Date"), commencing June 15, 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
December 17, 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.

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

                          7 1/8% SENIOR NOTE DUE 2017


         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 2017 of the Company, limited in
aggregate principal amount to $150,000,000.

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 December 15 and June 15
of each year (each an "Interest Payment Date"), commencing June 15, 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
December 17, 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.

<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
December 12, 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 $150,000,000.

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.





                                       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

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.

         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

portion of the principal amount of and accrued interest, if any, on such

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.
