                  WHEREAS, the parties hereto intend that the Merger shall be
accounted for as a "pooling of interests" for financial reporting purposes under
applicable United States accounting rules and the accounting standards of the
United States Securities and Exchange Commission (the "SEC"); and

                  WHEREAS, for United States federal income tax purposes, it is
intended that the Merger shall qualify as a reorganization under the provisions
of Section 368(a) of the United States Internal Revenue Code of 1986, as amended
(the "Code"), and the Treasury regulations thereunder (the "Regulations");

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth in
this Agreement, the parties hereto agree as follows:


                                    ARTICLE I

                  SECTION 1.01. The Merger. Upon the terms and subject to the
conditions set forth in this Agreement, and in accordance with the DGCL, at the

satisfaction or waiver of the conditions set forth in Article VII, at a closing
(the "Closing") to be held at the offices of Shearman & Sterling, 599 Lexington

                  SECTION 1.03. Effective Time. At the time of the Closing, the
parties shall cause the Merger to be consummated by filing a certificate of
merger (the "Certificate of Merger") with the Secretary of State of the State of

relevant provisions of, the DGCL (the date and time of such filing, or such
later date or time as set forth therein, being the "Effective Time").

                  SECTION 1.04. Effect of the Merger. At the Effective Time, the
effect of the Merger shall be as provided in the applicable provisions of the
DGCL. Without limiting the generality of the foregoing, and subject thereto, at
the Effective Time, except as otherwise provided herein, all the property,

and Officers of Surviving Corporation. At the Effective Time:

                  (a) the Certificate of Incorporation and the Bylaws of Merger
         Sub, as in effect immediately prior to the Effective Time, shall be the
         Certificate of Incorporation and the Bylaws of the Surviving
         Corporation (except that Article I of the Certificate of Incorporation
         shall be amended as of the Effective Time to read as follows: "The name
         of the Corporation is Waste Management, Inc.");

                  (b) the officers of the Company immediately prior to the
         Effective Time shall be the initial officers of the Surviving

         exist in any office of the Surviving Corporation, such vacancy may
         thereafter be filled in the manner provided by Law and the Certificate
         of Incorporation and Bylaws of the Surviving Corporation; and

                  (c) the directors of Merger Sub immediately prior to the
         Effective Time shall be the initial directors of the Surviving
         Corporation from and after the Effective Time, in each case until their
         successors are elected or appointed and qualified or until their
         resignation or removal. If, at the Effective Time, a vacancy shall
         exist on the Board of Directors of the Surviving Corporation, such
         vacancy may thereafter be filled in the manner provided by Law and the
         Certificate of Incorporation and Bylaws of the Surviving Corporation.

                                   ARTICLE II

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

                  SECTION 2.01. Conversion of Securities. At the Effective Time,
by virtue of the Merger and without any action on the part of Merger Sub, the
Company or the holders of any of the capital stock of Merger Sub or the Company:

                  (a) Each share of Company Common Stock issued and outstanding
         immediately prior to the Effective Time (other than any shares of
         Company Common Stock to be canceled pursuant to Section 2.01(b)) shall
         be converted, subject to Section 2.02(e), into the right to receive
         0.725 shares of Parent Common Stock (the "Exchange Ratio"); provided,
         however, that, in any event, if between the date of this Agreement and
         the Effective Time the outstanding shares of Parent Common Stock or
         Company Common Stock shall have been changed into a different number of
         shares or a different class, by reason of any stock dividend,
         subdivision, reclassification, recapitalization, split, combination or
         exchange of shares, the Exchange Ratio shall be correspondingly
         adjusted to reflect such stock dividend, subdivision, reclassification,
         recapitalization, split, combination or exchange of shares. All such
         shares of Company Common Stock shall no longer be outstanding and shall
         automatically be canceled and retired and shall cease to exist, and
         each certificate previously representing any such shares shall
         thereafter represent the right to receive a certificate representing
         the shares of Parent Common Stock into which such Company Common Stock
         was converted in the Merger. Certificates previously representing
         shares of Company Common Stock shall be exchanged for certificates
         representing whole shares of Parent Common Stock issued in
         consideration therefor upon the surrender of such certificates in
         accordance with the provisions of Section 2.02, without interest. No
         fractional share of Parent Common Stock shall be issued, and, in lieu
         thereof, a cash payment shall be made pursuant to Section 2.02(e)
         hereof.

                  (b) Each share of Company Common Stock held in the treasury of
         the Company and each share of Company Common Stock owned by Parent or
         any direct or indirect wholly owned subsidiary of Parent or of the
         Company immediately prior to the Effective Time shall be canceled and
         extinguished without any conversion thereof and no payment shall be
         made with respect thereto.

                  (c) Each share of common stock, par value $0.01 per share, of
         Merger Sub ("Merger Sub Common Stock") issued and outstanding
         immediately prior to the




<PAGE>


                                        5

         Effective Time shall be converted into and exchanged for one newly and
         validly issued, fully paid and nonassessable share of common stock of
         the Surviving Corporation.

                  (d) For all purposes of this Agreement, unless otherwise
         specified, all shares held by employee benefit plans of the Company (i)
         shall be deemed to be issued and outstanding, (ii) shall not be deemed
         to be held in the treasury of the Company and (iii) shall be converted
         into shares of Parent Common Stock in accordance with Section 2.01(a).

                  SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. As
of the Effective Time, Parent shall deposit, or shall cause to be deposited,
with a bank or trust company designated by Parent and reasonably acceptable to
the Company (the "Exchange Agent"), for the benefit of the holders of shares of
Company Common Stock, for exchange in accordance with this Article II, through
the Exchange Agent, certificates representing the shares of Parent Common Stock
(such certificates for shares of Parent Common Stock, together with cash in lieu
of fractional shares and any dividends or distributions with respect thereto,
being hereinafter referred to as the "Exchange Fund") issuable pursuant to
Section 2.01 in exchange for outstanding shares of Company Common Stock. The
Exchange Agent shall, pursuant to irrevocable instructions, deliver the Parent
Common Stock contemplated to be issued pursuant to Section 2.01 out of the
Exchange Fund. Except as contemplated by Section 2.02(e) hereof, the Exchange
Fund shall not be used for any other purpose.

                  (b) Exchange Procedures. Promptly after the Effective Time,
Parent shall instruct the Exchange Agent to mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "Certificates") (i)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon proper
delivery of the Certificates to the Exchange Agent, and shall be in customary
form) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of Parent Common
Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent
together with such letter of transmittal, duly executed, and such other
documents as may be required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing that number of whole shares of Parent Common Stock which such
holder has the right to receive in respect of the shares of Company Common Stock
formerly represented by such Certificate (after taking into account all shares
of Company Common Stock then held by such holder), cash in lieu of fractional
shares of Parent Common Stock to which such holder is entitled pursuant to
Section 2.02(e) and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.02(c), and the Certificate so surrendered shall
forthwith be canceled. No interest will be paid or accrued on any cash in lieu
of fractional shares or on any unpaid dividends and

                                        6

distributions payable to holders of Certificates. Notwithstanding anything to
the contrary contained herein, no certificate representing Parent Common Stock
or cash in lieu of a fractional share interest shall be delivered to a person
who is a Pooling Affiliate of Parent or the Company unless such affiliate has
theretofore executed and delivered to Parent the agreement referred to in
Section 6.04(a). In the event of a transfer of ownership of shares of Company
Common Stock which is not registered in the transfer records of the Company, a
certificate representing the proper number of shares of Parent Common Stock may
be issued to a transferee if the Certificate representing such shares of Company
Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.02, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the certificate representing shares of Parent Common Stock, cash in
lieu of any fractional shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.02(e) and any dividends or other distributions to
which such holder is entitled pursuant to Section 2.02(c).

                  (c) Distributions with Respect to Unexchanged Shares of Parent
Common Stock. No dividends or other distributions declared or made after the
Effective Time with respect to Parent Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent Common Stock represented thereby, and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 2.02(e), until the holder of such Certificate shall surrender such
Certificate. Subject to the effect of escheat, tax or other applicable Laws,
following surrender of any such Certificate, there shall be paid to the holder
of the certificates representing whole shares of Parent Common Stock issued in
exchange therefor, without interest, (i) promptly, the amount of any cash
payable with respect to a fractional share of Parent Common Stock to which such
holder is entitled pursuant to Section 2.02(e) and the amount of dividends or
other distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Parent Common Stock and (ii) at the
appropriate payment date, the amount of dividends or other distributions, with a
record date after the Effective Time but prior to surrender and a payment date
occurring after surrender, payable with respect to such whole shares of Parent
Common Stock.

                  (d) No Further Rights in Company Common Stock. All shares of
Parent Common Stock issued upon conversion of the shares of Company Common Stock
in accordance with the terms hereof (including any cash paid pursuant to Section
2.02(c) or (e)) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Common Stock, subject, however, to
the Surviving Corporation's obligation to pay dividends or make any other
distribution with respect to shares of Company Common Stock with a record date
prior to the Effective Time which have been declared or made by the




<PAGE>


                                        7

Company on such shares of Company Common Stock in accordance with the terms of
this Agreement (to the extent permitted under Section 5.01) prior to the date
hereof and which remain unpaid at the Effective Time.

                  (e) No Fractional Shares. (i) No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Certificates, no dividend or distribution with respect
to Parent Common Stock shall be payable on or with respect to any fractional
share and such fractional share interests will not entitle the owner thereof to
any rights of a stockholder of Parent.

                  (ii) As promptly as practicable following the Effective Time,
the Exchange Agent shall determine the excess of (x) the number of full shares
of Parent Common Stock delivered to the Exchange Agent by Parent pursuant to
Section 2.02(a) over (y) the aggregate number of full shares of Parent Common
Stock to be distributed to holders of Company Common Stock pursuant to Section
2.02(b) (such excess being herein called the "Excess Shares"). As soon after the
Effective Time as practicable, the Exchange Agent, as agent for such holders of
Parent Common Stock, shall sell the Excess Shares at then prevailing prices on
the New York Stock Exchange, Inc. (the "NYSE"), all in the manner provided in
paragraph (iii) of this Section 2.02(e).

                  (iii) The sale of the Excess Shares by the Exchange Agent
shall be executed on the NYSE through one or more member firms of the NYSE and
shall be executed in round lots to the extent practicable. The Exchange Agent
shall use all reasonable efforts to complete the sale of the Excess Shares as
promptly following the Effective Time as, in the Exchange Agent's reasonable
judgment, is practicable consistent with obtaining the best execution of such
sales in light of prevailing market conditions. Until the net proceeds of any
such sale or sales have been distributed to such holders of Company Common
Stock, the Exchange Agent will hold such proceeds in trust for such holders of
Company Common Stock as part of the Exchange Fund. Parent shall pay all
commissions, transfer taxes and other out-of-pocket transaction costs of the
Exchange Agent incurred in connection with such sale or sales of Excess Shares.
In addition, Parent shall pay the Exchange Agent's compensation and expenses in
connection with such sale or sales. The Exchange Agent shall determine the
portion of such net proceeds to which each holder of Company Common Stock shall
be entitled, if any, by multiplying the amount of the aggregate net proceeds by
a fraction the numerator of which is the amount of the fractional share interest
to which such holder of Company Common Stock is entitled (after taking into
account all shares of Company Common Stock then held by such holder) and the
denominator of which is the aggregate amount of fractional share interests to
which all holders of Certificates representing Company Common Stock are
entitled.

                                        8

                  (iv) Notwithstanding the provisions of subsections (ii) and
(iii) of this Section 2.02(e), Parent may elect, at its option exercised prior
to the Effective Time and in lieu of the issuance and sale of Excess Shares and
the making of the payments contemplated in such subsections, to pay to the
Exchange Agent an amount in cash sufficient for the Exchange Agent to pay each
holder of Company Common Stock an amount in cash equal to the product obtained
by multiplying (x) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Company Common
Stock held at the Effective Time by such holder) by (y) the closing price for a
share of Parent Common Stock on the NYSE Composite Transaction Tape on the first
business day immediately following the Effective Time and, in such case, all
references herein to the cash proceeds of the sale of the Excess Shares and
similar references shall be deemed to mean and refer to the payments calculated
as set forth in this Section 2.02(e)(iv).

                  (v) As soon as practicable after the determination of the
amount of cash, if any, to be paid to holders of Company Common Stock with
respect to any fractional share interests, the Exchange Agent shall promptly pay
such amounts to such holders of Company Common Stock subject to and in
accordance with the terms of Section 2.02(c).

                  (f) Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the holders of Company Common Stock for one
year after the Effective Time shall be delivered to Parent, upon demand, and any
holders of Company Common Stock who have not theretofore complied with this
Article II shall thereafter look only to Parent for the shares of Parent Common
Stock, any cash in lieu of fractional shares of Parent Common Stock to which
they are entitled pursuant to Section 2.02(e) and any dividends or other
distributions with respect to Parent Common Stock to which they are entitled
pursuant to Section 2.02(c), in each case, without any interest thereon.

                  (g) No Liability. Neither Parent nor the Company shall be
liable to any holder of shares of Company Common Stock for any such shares of
Parent Common Stock (or dividends or distributions with respect thereto) or cash
from the Exchange Fund delivered to a public official pursuant to any abandoned
property, escheat or similar Law.

                  (h) Lost Certificates. If any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and, if
required by Parent, the posting by such person of a bond, in such reasonable
amount as Parent may direct, as indemnity against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the shares of Parent
Common Stock, any cash in lieu of fractional shares of Parent Common Stock to
which the holders thereof are entitled pursuant




<PAGE>


                                        9

to Section 2.02(e) and any dividends or other distributions to which the holders
thereof are entitled pursuant to Section 2.02(c), in each case, without any
interest thereon.

                  (i) Withholding. Parent or the Exchange Agent shall be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of Company Common Stock such amounts as
Parent or the Exchange Agent are required to deduct and withhold under the Code,
or any provision of state, local or foreign tax law, with respect to the making
of such payment. To the extent that amounts are so withheld by Parent or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of Company Common Stock in respect
of whom such deduction and withholding was made by Parent or the Exchange Agent.

                  SECTION 2.03. Stock Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed and there shall be no
further registration of transfers of shares of Company Common Stock thereafter
on the records of the Company. From and after the Effective Time, the holders of
certificates representing shares of Company Common Stock outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to such
shares of Company Common Stock except as otherwise provided herein or by Law. On
or after the Effective Time, any Certificates presented to the Exchange Agent or
Parent for any reason shall be converted into the shares of Parent Common Stock,
any cash in lieu of fractional shares of Parent Common Stock to which the
holders thereof are entitled pursuant to Section 2.02(e) and any dividends or
other distributions to which the holders thereof are entitled pursuant to
Section 2.02(c).

                  SECTION 2.04. Options to Purchase Company Common Stock. (a) At
the Effective Time, each option or warrant granted by the Company to purchase
shares of Company Common Stock (the "Company Stock Options"), which is
outstanding and unexercised immediately prior to the Effective Time, shall be
assumed by Parent and converted into an option or warrant to purchase shares of
Parent Common Stock in such number and at such exercise price as provided below
and otherwise having the same terms and conditions as in effect immediately
prior to the Effective Time (except to the extent that such terms, conditions
and restrictions may be altered in accordance with their terms as a result of
the Merger contemplated hereby):

                  (i) the number of shares of Parent Common Stock to be subject
         to the converted option or warrant shall be equal to the product of (x)
         the number of shares of Company Common Stock subject to the original
         option or warrant and (y) the Exchange Ratio;





<PAGE>


                                       10

                  (ii) the exercise price per share of Parent Common Stock under
         the converted option or warrant shall be equal to (x) the exercise
         price per share of Company Common Stock under the original option or
         warrant divided by (y) the Exchange Ratio; and

                  (iii) upon each exercise of options or warrants by a holder
         thereof, the aggregate number of shares of Parent Common Stock
         deliverable upon such exercise shall be rounded down, if necessary, to
         the nearest whole share and the aggregate exercise price shall be
         rounded up, if necessary, to the nearest cent.

The adjustments provided herein with respect to any options which are "incentive
stock options" (as defined in Section 422 of the Code) shall be effected in a
manner consistent with the requirements of Section 424(a) of the Code.

                  (b) Parent shall take all corporate action necessary to
reserve and make available for issuance a sufficient number of shares of Parent
Common Stock for delivery under Company Stock Options assumed by Parent. At or
prior to the Effective Time, Parent shall file a registration statement on Form
S-8 (or any successor or other appropriate forms) with respect to the shares of
Parent Common Stock subject to such options and shall use its best efforts to
maintain the effectiveness of such registration statement or registration
statements (and maintain the current status of the prospectus or prospectuses
contained therein) for so long as such options remain outstanding.

                  SECTION 2.05. Restricted Stock. At the Effective Time, any
restricted shares of Company Common Stock awarded pursuant to any plan,
arrangement or transaction and outstanding immediately prior to the Effective
Time shall be assumed by Parent and converted into restricted shares of Parent
Common Stock in accordance with Section 2.01 hereof, subject to the same terms,
conditions and restrictions as in effect immediately prior to the Effective
Time, except to the extent that such terms, conditions and restrictions may be
altered in accordance with their terms as a result of the Merger contemplated
hereby.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company hereby represents and warrants to Parent that:

                  SECTION 3.01. Organization and Qualification; Subsidiaries.
Each of the Company and each subsidiary of the Company (the "Company
Subsidiaries") has been duly organized and is validly existing and in good
standing (to the extent applicable) under the laws of the jurisdiction of its
incorporation or organization, as the case may be, and has the requisite
corporate power and authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing or in good
standing or to have such power, authority and governmental approvals would not,
individually or in the aggregate, have a Company Material Adverse Effect. Each
of the Company and each Company Subsidiary is duly qualified or licensed to do
business, and is in good standing (to the extent applicable), in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that would not, individually or in the aggregate, have any change in or
effect on the business of the Company and the Company Subsidiaries that is, or
is reasonably likely to be, materially adverse to the business, assets
(including intangible assets), liabilities (contingent or otherwise), condition
(financial or otherwise) or results of operations of the Company and the Company
Subsidiaries taken as a whole (a "Company Material Adverse Effect"). Section
3.01(a) of the Disclosure Schedule delivered by the Company to Parent prior to
the execution of this Agreement (the "Company Disclosure Schedule") sets forth a
complete and correct list of all of the Company Subsidiaries other than the
subsidiaries of Waste Management International plc (together with its
subsidiaries, "WME"). Except as set forth in Section 3.01(b) of the Company
Disclosure Schedule, neither the Company nor any Company Subsidiary (except for
WME and NSC Corporation and its subsidiaries (collectively, "NSC")) holds any
interest in any corporation, limited liability company, partnership, joint
venture or other legal entity of any kind.

                  SECTION 3.02. Certificate of Incorporation and Bylaws. The
copy of the Company's Restated Certificate of Incorporation that is incorporated
by reference as an exhibit to the Company's Form 10-Q for the period ending June
30, 1997 and the copy of the Company's Bylaws that is incorporated by reference
as an exhibit to the Company's Form 10-Q for the period ending September 30,
1997 are complete and correct copies thereof. Such Restated Certificate of
Incorporation and Bylaws are in full force and effect. The Company is not in
violation of any of the provisions of its Restated Certificate of Incorporation
or Bylaws.

                                       12

                  SECTION 3.03. Capitalization. The authorized capital stock of
the Company consists of 1,500,000,000 shares of Company Common Stock and
50,000,000 shares of preferred stock, par value $1.00 per share (the "Company
Preferred Stock"). As of December 31, 1997, (i) 507,101,774 shares of Company
Common Stock were issued (including treasury shares), all of which were validly
issued, fully paid and nonassessable, (ii) 2,500,000 shares of Series A
Preferred Stock were authorized, none of which were issued, (iii) 52,063,991
shares of Company Common Stock were held in the treasury of the Company or by
any direct or indirect wholly owned Company Subsidiary (including those in the
employee stock benefit trust), (iv) 14,650,015 shares of Company Common Stock
were reserved for future issuance pursuant to the terms of the Company's
Convertible Subordinated Notes due 2005 and the Company's Liquid Yield Option
Notes due 2001, 2010 and 2012 (together, the "Company Subordinated Notes") and
(v) 21,998,096 shares of Company Common Stock were reserved for issuance
pursuant to outstanding Company Stock Options issued under the benefits plans
set forth on Section 3.03(a) of the Company Disclosure Schedule (the "Company
Stock Plans"). Between December 31, 1997 and the date of this Agreement, an
aggregate of 10,000 Company Stock Options have been granted, excluding Company
Stock Options with respect to up to 5.3 million shares of Company Common Stock
granted on March 9, 1998 under the Company 1997 Equity Incentive Plan (the
"March 1998 Options"), and, since that date, no awards of restricted stock have
been made under the Company Stock Plans, and, since that date, no shares of
Company Common Stock (or securities convertible into Company Common Stock) have
been issued other than those shares of Company Common Stock reserved for
issuance as set forth in this Section 3.03. Except for the Company Stock Options
granted pursuant to the Company Stock Plans and shares of Company Common Stock
issuable pursuant to the Company Stock Plans and upon the conversion of the
Company Subordinated Notes or pursuant to agreements or arrangements described
in Section 3.03(a) of the Company Disclosure Schedule, there are no options,
warrants or other rights, agreements, arrangements or commitments of any
character to which the Company is a party or by which the Company is bound
relating to the issued or unissued capital stock of the Company or any Company
Subsidiary (other than WME and NSC) or obligating the Company or any Company
Subsidiary (other than WME and NSC) to issue or sell any shares of capital stock
of, or other equity interests in, the Company or any Company Subsidiary (other
than WME and NSC). The terms of each grant of a March 1998 Option provide that,
as a condition to such grant, the optionee must waive any rights thereunder
arising as a result of any "change in control" of the Company that may be caused
by the Merger. All shares of Company Common Stock subject to issuance as
aforesaid, upon issuance prior to the Effective Time on the terms and conditions
specified in the instruments pursuant to which they are issuable, will be duly
authorized, validly issued, fully paid and nonassessable. Except as set forth in
Section 3.03(a) of the Company Disclosure Schedule, there are no outstanding
contractual obligations of the Company or any Company Subsidiary (other than WME
and NSC) to repurchase, redeem or otherwise acquire any shares of Company Common
Stock or any capital stock of any Company Subsidiary. Except as




<PAGE>


                                       13

disclosed in Section 3.03(a) of the Company Disclosure Schedule, each
outstanding share of capital stock of each Company Subsidiary is duly
authorized, validly issued, fully paid and nonassessable and each such share
owned by the Company or another Company Subsidiary is free and clear of all
security interests, liens, claims, pledges, options, rights of first refusal,
agreements, limitations on the Company's or such other Company Subsidiary's
voting rights, charges and other encumbrances of any nature whatsoever, except
where the failure to own such shares free and clear would not, individually or
in the aggregate, have a Company Material Adverse Effect. Except as set forth in
Section 3.03(b) of the Company Disclosure Schedule or as set forth in the
Company Reports (as hereinafter defined), there are no material outstanding
contractual obligations of the Company or any Company Subsidiary (other than WME
and NSC) to provide funds to, or make any material investment (in the form of a
loan, capital contribution or otherwise) in, any Company Subsidiary which is not
wholly owned by the Company or in any other person.

                  SECTION 3.04. Authority Relative to this Agreement. The
Company has all necessary corporate power and authority to execute and deliver
this Agreement, to perform its obligations hereunder and to consummate the
Merger. The execution and delivery of this Agreement by the Company and the
consummation by the Company of the Merger contemplated hereby have been duly and
validly authorized by all necessary corporate action, and no other corporate
proceedings on the part of the Company are necessary to authorize this Agreement
or to consummate the Merger (other than, with respect to the Merger, the
adoption of this Agreement by the affirmative vote of a majority of the
outstanding shares of Company Common Stock entitled to vote with respect thereto
at the Company Stockholders' Meeting and the filing and recordation of the
Certificate of Merger as required by the DGCL). This Agreement has been duly
executed and delivered by the Company and, assuming the due authorization,
execution and delivery by the other parties hereto and thereto, constitutes a
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms.

                  SECTION 3.05. No Conflict; Required Filings and Consents. (a)
The execution and delivery of this Agreement by the Company does not, and the
performance by the Company of its obligations hereunder and the consummation of
the Merger will not, (i) conflict with or violate any provision of the Restated
Certificate of Incorporation or Bylaws of the Company or any equivalent
organizational documents of any Company Subsidiary (other than WME and NSC),
(ii) assuming that all consents, approvals, authorizations and permits described
in Section 3.05(b) have been obtained and all filings and notifications
described in Section 3.05(b) have been made, conflict with or violate any Law
applicable to the Company or any Company Subsidiary or by which any property or
asset of the Company or any Company Subsidiary is bound or affected or (iii)
except as set forth in Section 3.05(a) of the Company Disclosure Schedule,
result in any breach of or constitute a default (or an event




<PAGE>


                                       14

which with the giving of notice or lapse of time or both would become a default)
under, or give to others any right of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on any
property or asset of the Company or any Company Subsidiary pursuant to, any
note, bond, mortgage, indenture, contract, agreement, lease, license, Company
Permit, franchise or other instrument or obligation, except, with respect to
clauses (ii) and (iii), for any such conflicts, violations, breaches, defaults
or other occurrences which would neither, individually or in the aggregate, (A)
have a Company Material Adverse Effect nor (B) prevent or materially delay the
performance by the Company of its obligations pursuant to this Agreement or the
consummation of the Merger.

                  (b) The execution and delivery of this Agreement by the
Company does not, and the performance by the Company of its obligations
hereunder or the consummation of the Merger will not, require any consent,
approval, authorization or permit of, or filing by the Company with or
notification by the Company to, any United States federal, state or local or any
supranational or foreign governmental, regulatory or administrative authority,
agency or commission or any court, tribunal or arbitral body (a "Governmental
Entity"), except (i) applicable requirements of the Securities Exchange Act of
1934, as amended (together with the rules and regulations promulgated
thereunder, the "Exchange Act"), the Securities Act of 1933, as amended
(together with the rules and regulations promulgated thereunder, the "Securities
Act"), state securities or "blue sky" laws ("Blue Sky Laws"), the rules and
regulations of the NYSE, state takeover laws, the premerger notification
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations thereunder (the "HSR Act"), the filing
and recordation of the Certificate of Merger as required by the DGCL, and as set
forth in Section 3.05(b) of the Company Disclosure Schedule, and (ii) where
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not (A) prevent or materially delay
the performance by the Company of its obligations pursuant to this Agreement and
the consummation of the Merger or (B) individually or in the aggregate have a
Company Material Adverse Effect.

                  SECTION 3.06. Permits; Compliance with Laws. Each of the
Company and the Company Subsidiaries (other than WME) is in possession of all
franchises, grants, authorizations, licenses, permits, easements, variances,
exceptions, consents, certificates, approvals and orders of any Governmental
Entity necessary for the Company or any Company Subsidiary (other than WME) to
own, lease and operate its properties or to carry on its business as it is now
being conducted (the "Company Permits"), and all such Company Permits are valid
and in full force and effect, except where the failure to have, or the
suspension or cancellation of, any of the Company Permits, or the failure of any
of such Company Permits to be valid and in full force and effect, would not,
individually or in the aggregate, (i) have a Company Material Adverse Effect, or
(ii) except as described in Section 3.05(b) of the




<PAGE>


                                       15

Company Disclosure Schedule, prevent or materially delay the performance by the
Company of its obligations pursuant to this Agreement and the consummation of
the Merger, and, as of the date of this Agreement, no suspension or cancellation
of any of the Company Permits is pending or, to the knowledge of the Company,
threatened, except where the failure to have, or the suspension or cancellation
of, any of the Company Permits would not, individually or in the aggregate, (i)
have a Company Material Adverse Effect or (ii) prevent or materially delay the
performance by the Company of its obligations pursuant to this Agreement and the
consummation of the Merger. Except as disclosed in Section 3.06(a) of the
Company Disclosure Schedule, neither the Company nor any Company Subsidiary
(other than WME) is in conflict with, or in default or violation of, (i) any Law
applicable to the Company or any Company Subsidiary (other than WME) or by which
any property or asset of the Company or any Company Subsidiary (other than WME)
is bound or affected or (ii) any Company Permits, except in the case of clauses
(i) and (ii) for any such conflicts, defaults or violations that would neither
individually or in the aggregate, (A) have a Company Material Adverse Effect nor
(B) prevent or materially delay the performance by the Company of its
obligations pursuant to this Agreement and the consummation of the Merger. As
used in this Agreement, "Law" means any federal, state or local statute, law,
ordinance, regulation, rule, code, order, judgment, writ, stipulation, award,
injunction, decree or other requirement or rule of law of the United States or
any other jurisdiction.

                  SECTION 3.07. SEC Filings; Financial Statements. (a) Other
than those listed on Section 3.07(a)(i) of the Company Disclosure Schedule (the
"Reporting Company Subsidiaries") and other than NSC, no Company Subsidiary is
subject to the periodic reporting requirements of the Exchange Act or required
to file any form, report or other document with the SEC, NYSE, any other stock
exchange or any other comparable Governmental Entity. The Company and each
Reporting Company Subsidiary has timely filed all periodic reports and all other
documents required to be filed by it with the SEC under the Exchange Act since
December 31, 1996 through the date of this Agreement (collectively and as
amended, the "Company Reports"). Except as set forth in Section 3.07(a)(iii) of
the Company Disclosure Schedule or except as would not have a Company Material
Adverse Effect, each Company Report (i) was prepared in accordance with the
requirements of the Exchange Act and (ii) did not at the time it was filed
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading.

                  (b) Except as set forth on Section 3.07(b)(i) of the Company
Disclosure Schedule, each of the consolidated financial statements (including,
in each case, any notes thereto) contained in the Company Reports was prepared
in accordance with United States generally accepted accounting principles ("U.S.
GAAP") applied on a consistent basis throughout the periods indicated (except as
may be indicated in the notes thereto) and each




<PAGE>


                                       16

presented fairly, in all material respects, the consolidated financial position
of the Company and the consolidated Company Subsidiaries (with respect to
Company Reports filed by the Company) or the consolidated financial position of
the Reporting Company Subsidiary (with respect to Company Reports filed by a
Reporting Company Subsidiary) as at the respective dates thereof and the
consolidated results of their operations and their consolidated cash flows for
the respective periods indicated therein, except as otherwise noted therein
(subject, in the case of unaudited statements, to normal and recurring year-end
adjustments which were not and are not expected, individually or in the
aggregate, to have a Company Material Adverse Effect). The books and records of
the Company and the Company Subsidiaries (other than WME and NSC) are being
maintained in accordance with U.S. GAAP and any other applicable legal and
accounting requirements.

                  (c) Except as and to the extent set forth on Section 3.07(c)
of the Company Disclosure Schedule, none of the Company or any Company

disclosed in the Company Reports or in Section 3.10 of the Company Disclosure
Schedule, neither the Company nor, to the knowledge of the Company, any of its
affiliates has taken or agreed to take any action (other than actions
contemplated by this Agreement) that would prevent the Merger from qualifying
for "pooling of interests" accounting treatment under applicable United States
accounting rules, including, without limitation, applicable SEC accounting
standards, or would prevent the Merger from constituting a transaction
qualifying under Section 368(a) of




<PAGE>


                                       20

Parent Common Stock), with a fair market value equal to the cash that would
otherwise have been payable thereunder.

disclosed in the Company Reports or in Section 3.11 of the Company Disclosure
Schedule, there is no contract or agreement that is material to the business,

Schedule, neither the Company nor any Company Subsidiary is in violation of or

any loan or credit agreement, note, bond, mortgage, indenture or lease, or any
other contract, agreement, arrangement or understanding to which it is a party
or by which it or any of its properties or assets is bound, except for
violations or defaults that would not, individually or in the aggregate, result

to the knowledge of the Company, there are no existing facts or circumstances
that would be reasonably likely to result in such a suit, claim, action,
proceeding or investigation. Except as disclosed to Parent, the Company is not
aware of any facts or circumstances which would result in the denial of

Subsidiaries in respect of such suits, claims, actions,

         Environmental Law;

                  (c) neither the Company nor any Company Subsidiary (other than

                                   ARTICLE IV

                        REPRESENTATIONS AND WARRANTIES OF
                              PARENT AND MERGER SUB

                  Parent and Merger Sub hereby jointly and severally represent
and warrant to the Company that:

                  SECTION 4.01. Organization and Qualification; Subsidiaries.
Each of Parent, Merger Sub and each other subsidiary of Parent (together with
Merger Sub, the "Parent Subsidiaries") has been duly organized and is validly
existing and in good standing (to the




<PAGE>


                                       25

extent applicable) under the laws of the jurisdiction of its incorporation or
organization, as the case may be, and has the requisite corporate power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as it is now being conducted, except
where the failure to be so organized, existing or in good standing or to have
such power, authority and governmental approvals would not, individually or in
the aggregate, have a Parent Material Adverse Effect. Each of Parent and each
Parent Subsidiary is duly qualified or licensed to do business, and is in good
standing (to the extent applicable), in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failures to be
so qualified or licensed and in good standing that would not, individually or in
the aggregate, have any change in or effect on the business of Parent and the
Parent Subsidiaries that is, or is reasonably likely to be, materially adverse
to the business, assets (including intangible assets), liabilities (contingent
or otherwise), condition (financial or otherwise) or results of operations of
Parent and the Parent Subsidiaries taken as a whole (a "Parent Material Adverse
Effect"). Section 4.01(a) of the Disclosure Schedule delivered by Parent to the
Company prior to the execution of this Agreement (the "Parent Disclosure
Schedule") sets forth a complete and correct list of all of Parent Subsidiaries.
Except as set forth in Section 4.01(b) of the Parent Disclosure Schedule,
neither Parent nor any Parent Subsidiary holds any interest in any corporation,
limited liability company, partnership, joint venture or other legal entity of
any kind.

                  SECTION 4.02. Certificate of Incorporation and Bylaws. The
copy of Parent's Restated Certificate of Incorporation that is incorporated by
reference as an exhibit to Parent's Form 10-Q for the period ending September
30, 1997 and the copy of Parent's Bylaws that is incorporated by reference as an
exhibit to Parent's Form 10-K for the period ending December 31, 1996 (the
"Parent 1996 10-K") are complete and correct copies thereof. Parent has
heretofore furnished to the Company a complete and correct copy of the
Certificate of Incorporation and Bylaws of Merger Sub. Such Restated Certificate
of Incorporation, Certificate of Incorporation and Bylaws of Parent and Merger
Sub are in full force and effect. Neither Parent nor Merger Sub is in violation
of any of the provisions of its Certificate of Incorporation or Bylaws.

                  SECTION 4.03. Capitalization. The authorized capital stock of
Parent consists of 500,000,000 shares of Parent Common Stock and 10,000,000
shares of preferred stock (the "Parent Preferred Stock"). As of February 27,
1998, (i) 218,866,174 shares of Parent Common Stock were issued and outstanding,
all of which were validly issued, fully paid and nonassessable, (ii) no shares

("Parent Stock Options") issued under the benefits plans set forth on Section
4.03(v) of the Parent Disclosure Schedule or otherwise (the "Parent Stock
Plans") and (vi) 4,035,572 shares of Parent Common Stock were reserved for

Disclosure Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character to which Parent is a party or by
which Parent is bound relating to the issued or unissued capital stock of Parent
or any Parent Subsidiary or obligating Parent or any Parent Subsidiary to issue

authorized, validly issued, fully paid and nonassessable. Except as set forth in
Section 4.03 of the Parent Disclosure Schedule, there are no outstanding
contractual obligations of Parent or any Parent Subsidiary to repurchase, redeem
or otherwise acquire any shares of Parent Common Stock or any capital stock of
any Parent Subsidiary. Except as disclosed in Section 4.03 of the Parent
Disclosure Schedule, each outstanding share of capital stock of each Parent
Subsidiary is duly authorized, validly issued, fully paid and nonassessable and
each such share owned by Parent or another Parent Subsidiary is free and clear
of all security interests, liens, claims, pledges, options, rights of first
refusal, agreements, limitations on Parent's or such other Parent Subsidiary's
voting rights, charges and other encumbrances of any nature whatsoever, except
where the failure to own such shares free and clear would not, individually or
in the aggregate, have a Parent Material Adverse Effect. Except as set forth in
Section 4.03 of the Parent Disclosure Schedule or as set forth in the Parent
Reports (as hereinafter defined), there are no material outstanding contractual
obligations of Parent or any Parent Subsidiary to provide funds to, or make any
material investment (in the form of a loan, capital contribution or otherwise)
in, any Parent Subsidiary which is not wholly owned by Parent or in any other
person.

                  SECTION 4.04. Authority Relative to this Agreement. Each of
Parent and Merger Sub has all necessary corporate power and authority to execute
and deliver this

                                       27

Agreement, to perform its obligations hereunder and to consummate the Merger.
Each of (i) the execution and delivery of this Agreement by Parent and Merger
Sub and the consummation by Parent and Merger Sub of the transactions

Incorporation of Parent to increase the number of authorized shares of Parent
Common Stock to a number sufficient to consummate the transactions contemplated
hereby and to change Parent's name, as of the Effective Time, to "Waste
Management, Inc." (the "Certificate Amendment") and (iii) the issuance (the
"Share Issuance") of shares of Parent Common Stock in the Merger, have been duly
and validly authorized by all necessary corporate action, and no other corporate
proceedings on the part of Parent or Merger Sub are necessary to authorize this
Agreement or to consummate such transactions (other than, with respect to (a)
the adoption of the Certificate Amendment, the affirmative vote of a majority of
the votes entitled to be cast and (b) the adoption of the Share Issuance, the
approval thereof by the affirmative vote of a majority of votes cast by the
holders of outstanding shares of Parent Common Stock at the Parent Stockholders'
Meeting). This Agreement has been duly executed and delivered by Parent and
Merger Sub and, assuming the due authorization, execution and delivery by the
Company, this Agreement constitutes a legal, valid and binding obligation of
each of Parent and Merger Sub, enforceable against Parent and Merger Sub, as the
case may be, in accordance with its terms.

                  SECTION 4.05. No Conflict; Required Filings and Consents. (a)
The execution and delivery of this Agreement by Parent and Merger Sub, do not,
and the performance by Parent and Merger Sub of their respective obligations
hereunder and the consummation of the Merger will not, (i) conflict with or
violate any provision of the Restated Certificate of Incorporation or Bylaws of
Parent or any equivalent organizational documents of any Parent Subsidiary
(assuming that the Certificate Amendment is approved as contemplated by this
Agreement), (ii) assuming that all consents, approvals, authorizations and
permits described in Section 4.05(b) have been obtained and all filings and
notifications described in Section 4.05(b) have been made, conflict with or

to others any right of termination, amendment, acceleration or cancellation of,
or result in the creation of a lien or other encumbrance on any property or
asset of Parent or any Parent Subsidiary pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, Parent Permit, franchise or
other instrument or obligation, except, with respect to clauses (ii) and (iii),
for any such conflicts, violations, breaches, defaults or other occurrences
which would neither, individually or in the aggregate, (A) have a Parent
Material Adverse Effect nor (B) prevent or materially delay the performance by
Parent or Merger Sub of their respective obligations pursuant to this Agreement
or the consummation of the Merger.

                                       28

                  (b) The execution and delivery of this Agreement by each of
Parent and Merger Sub does not, and the performance by Parent and Merger Sub of
their respective obligations hereunder or the consummation of the Merger will
not, require any consent, approval, authorization or permit of, or filing by
Parent or Merger Sub with or notification by Parent or Merger Sub to, any
Governmental Entity, except (i) applicable requirements of the Exchange Act, the
Securities Act, Blue Sky Laws, the rules and regulations of the NYSE, state
takeover laws, the premerger notification requirements of the HSR Act, the
filing and recordation of the Certificate of Merger as required by the DGCL, and
as set forth in Section 4.05(b) of the Parent Disclosure Schedule, and (ii)
where failure to obtain such consents, approvals, authorizations or permits, or
to make such filings or notifications, would not (A) prevent or materially delay
the performance by Parent or Merger Sub of their respective obligations pursuant
to this Agreement and the consummation of the Merger or (B) individually or in
the aggregate have a Parent Material Adverse Effect.

                  SECTION 4.06. Permits; Compliance with Laws. Each of Parent
and the Parent Subsidiaries is in possession of all franchises, grants,
authorizations, licenses, permits, easements, variances, exceptions, consents,
certificates, approvals and orders of any Governmental Entity necessary for
Parent or any Parent Subsidiary to own, lease and operate its properties or to
carry on its business as it is now being conducted (the "Parent Permits"), and
all such Parent Permits are valid and in full force and effect, except where the
failure to have, or the suspension or cancellation of, any of Parent Permits, or
the failure of any such Parent Permits to be valid and in full force and effect,
would not, individually or in the aggregate, (i) have a Parent Material Adverse
Effect, or (ii) prevent or materially delay the performance by Parent or Merger
Sub of their respective obligations pursuant to this Agreement and the
consummation of the Merger, and, as of the date of this Agreement, no suspension
or cancellation of any of Parent Permits is pending or, to the knowledge of
Parent, threatened, except where the failure to have, or the suspension or
cancellation of, any of Parent Permits would not, individually or in the
aggregate, (i) have a Parent Material Adverse Effect or (ii) prevent or
materially delay the performance by Parent or Merger Sub of their respective
obligations pursuant to this Agreement and the consummation of the Merger.
Except as disclosed in Section 4.06 of the Parent Disclosure Schedule, neither
Parent nor any Parent Subsidiary is in conflict with, or in default or violation
of, (i) any Law applicable to Parent or any Parent Subsidiary or by which any
property or asset of Parent or any Parent Subsidiary is bound or affected or
(ii) any Parent Permits, except in the case of clauses (i) and (ii) for any such
conflicts, defaults or violations that would neither individually or in the
aggregate, (A) have a Parent Material Adverse Effect nor (B) prevent or
materially delay the performance by Parent or Merger Sub of their respective
obligations pursuant to this Agreement and the consummation of the Merger.

                  SECTION 4.07. SEC Filings; Financial Statements. (a) Other
than those listed on Section 4.07(a)(i) of the Parent Disclosure Schedule (the
"Reporting Parent Subsidiaries"), no Parent Subsidiary is subject to the
periodic reporting requirements of the Exchange Act or required to file any
form, report or other document with the SEC, NYSE, any other stock exchange or
any other comparable Governmental Entity. Except as disclosed in Section
4.07(a)(ii) of the Parent Disclosure Schedule, Parent and each Reporting Parent
Subsidiary has timely filed all forms, reports and documents required to be
filed by it with the SEC, the NYSE, any other stock exchange or comparable
Governmental Entity since January 1, 1995 through the date of this Agreement
(collectively and as amended, the "Parent Reports"). Except as would not have a
Parent Material Adverse Effect, each Parent Report (i) was prepared in
accordance with the requirements of the Securities Act, the Exchange Act, the
NYSE, other stock exchange or comparable Governmental Entity, as the case may
be, and (ii) except as set forth in Section 4.07(a)(iii) of the Parent
Disclosure Schedule, did not at the time it was filed contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading.

                  (b) Each of the consolidated financial statements (including,
in each case, any notes thereto) contained in the Parent Reports was prepared in
accordance with U.S. GAAP applied on a consistent basis throughout the periods
indicated (except as may be indicated in the notes thereto) and each presented
fairly, in all material respects, the consolidated financial position of Parent
and the consolidated Parent Subsidiaries as at the respective dates thereof and
the consolidated results of their operations and their consolidated cash flows
for the respective periods indicated therein, except as otherwise noted therein
(subject, in the case of unaudited statements, to normal and recurring year-end
adjustments which were not and are not expected, individually or in the
aggregate, to have a Parent Material Adverse Effect). The books and records of
Parent and the Parent Subsidiaries have been, and are being, maintained in
accordance with U.S. GAAP and any other applicable legal and accounting
requirements.

                  (c) Except as and to the extent set forth on the consolidated
balance sheet of Parent and the Parent Subsidiaries as reported in the Parent
Reports, including the notes thereto, none of Parent or any Parent Subsidiary
has any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) that would be required to be reflected on a balance
sheet or in notes thereto prepared in accordance with U.S. GAAP, except for
liabilities or obligations incurred in the ordinary course of business since
January 1, 1997 that would not, individually or in the aggregate, have a Parent
Material Adverse Effect.

                  SECTION 4.08. Absence of Certain Changes or Events. Since
January 1, 1997, except as contemplated by or as disclosed in this Agreement, as
set forth in Section 4.08




<PAGE>


                                       30

of the Parent Disclosure Schedule or as disclosed in any Parent Report filed
since January 1, 1997, Parent and the Parent Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, since such date, there has not been (i) any Parent Material
Adverse Effect or any event or development that would have a Parent Material
Adverse Effect, excluding any changes and effects resulting from changes in
economic, regulatory or political conditions or changes in conditions generally
applicable to the industries in which Parent and the Parent Subsidiaries are
involved, (ii) any event that could reasonably be expected to prevent or
materially delay the performance of Parent's and Merger Sub's obligations
pursuant to this Agreement and the consummation of the Merger by Parent and
Merger Sub, (iii) any material change by Parent in its accounting methods,
principles or practices, (iv) any declaration, setting aside or payment of any
dividend or distribution in respect of the shares of Parent Common Stock or any
redemption, purchase or other acquisition of any of Parent's securities or (v)
any increase in the compensation or benefits or establishment of any bonus,
insurance, severance, deferred compensation, pension, retirement, profit
sharing, stock option (including, without limitation, the granting of stock
options, stock appreciation rights, performance awards or restricted stock
awards), stock purchase or other employee benefit plan, or any other increase in
the compensation payable or to become payable to any executive officers of
Parent or any Parent Subsidiary except in the ordinary course of business
consistent with past practice.

                  SECTION 4.09. Employee Benefit Plans; Labor Matters. (a) With
respect to each employee benefit plan, program, arrangement and contract
(including, without limitation, any "employee benefit plan", as defined in
Section 3(3) of ERISA maintained or contributed to by Parent or any Parent
Subsidiary, or with respect to which Parent or any Parent Subsidiary could incur
liability under Section 4069, 4212(c) or 4204 of ERISA (the "Parent Benefit
Plans"), Parent has delivered (or will, within 15 days of the date hereof,
deliver) to the Company a true and correct copy of (i) such Parent Benefit Plan
and the most recent summary plan description related to each Company Benefit
Plan for which a summary plan description is required, (ii) each trust agreement
or other funding arrangement relating to such Parent Benefit Plan, (iii) the
most recent annual report (Form 5500) filed with the IRS, (iv) the most recent
actuarial report or financial statement relating to a Parent Benefit Plan and
(v) the most recent determination letter issued by the IRS with respect to any
Parent Benefit Plan qualified under Section 401(a) of the Code.

                  (b) Each Parent Benefit Plan has been administered in all
material respects in accordance with its terms and all contributions required to
be made under the terms of any of the Parent Benefit Plans as of the date of
this Agreement have been timely made or have been reflected on the most recent
consolidated balance sheet filed or incorporated by reference in the Parent
Reports prior to the date of this Agreement. Except as set forth in Section
4.09(b) of the Parent Disclosure Schedule, with respect to the Parent Benefit
Plans, no event has occurred




<PAGE>


                                       31

and, to the knowledge of Parent, there exists no condition or set of
circumstances in connection with which Parent or any Parent Subsidiary could be
subject to any liability under the terms of such Parent Benefit Plans, ERISA,
the Code or any other applicable Law which, in any case, would individually or
in the aggregate have a Parent Material Adverse Effect.

                  (c) Except as set forth in Section 4.09(c) of the Parent
Disclosure Schedule or except as would not have a Parent Material Adverse
Effect, with respect to each Parent Benefit Plan that is not subject to United
States Law (a "Parent Foreign Benefit Plan"):

                  (i) all employer and employee contributions to each Parent
         Foreign Benefit Plan required by Law or by the terms of such Parent
         Foreign Benefit Plan have been made or, if applicable, accrued in
         accordance with normal accounting practices and a pro rata contribution
         for the period from the date hereof to and including the Effective Time
         has been made or accrued in accordance with normal accounting
         principles;

                  (ii) the fair market value of the assets of each funded Parent
         Foreign Benefit Plan, the liability of each insurer for any Parent
         Foreign Benefit Plan funded through insurance or the book reserve
         established for any Parent Foreign Benefit Plan, together with any
         accrued contributions, is sufficient to procure or provide for the
         accrued benefit obligations, as of the Effective Time, with respect to
         all current and former participants in such plan according to the
         actuarial assumptions and valuations most recently used to determine
         employer contributions to such Parent Foreign Benefit Plan and no
         transaction contemplated by this Agreement shall cause such assets or
         insurance obligations to be less than such benefit obligations; and

                  (iii) each Parent Foreign Benefit Plan required to be
         registered has been registered and has been maintained in good standing
         with the appropriate regulatory authorities.

                  (d) As of the date of this Agreement, there is no labor
dispute, strike or work stoppage against Parent or any Parent Subsidiary pending
or, to the knowledge of Parent, threatened which may interfere with the
respective business activities of Parent or any Parent Subsidiary, except where
such dispute, strike or work stoppage would not have a Parent Material Adverse
Effect. As of the date of this Agreement, to the knowledge of the Parent, none
of Parent, any Parent Subsidiary, or any of their respective representatives or
employees has committed any unfair labor practice in connection with the
operation of the respective businesses of Parent or any Parent Subsidiary, and
there is no charge or complaint against Parent or any Parent Subsidiary by the
National Labor Relations Board or any comparable governmental agency pending or
threatened in writing, except where such unfair labor practice, charge or
complaint would not have a Parent Material Adverse Effect.

                  (e) Parent has made available to the Company true and complete
copies of (i) all employment agreements with executive officers of Parent and
with each other officer of Parent and of each Parent Subsidiary providing for
annual compensation in excess of $250,000, (ii) all severance plans, agreements,
programs and policies of Parent and each Parent Subsidiary with or relating to
their respective employees, and (iii) all plans, programs, agreements and other
arrangements of Parent and each Parent Subsidiary with or relating to their
respective employees which contain "change of control" provisions.

                  (f) No amount paid or payable by Parent or any Parent
Subsidiary in connection with the transactions contemplated hereby either solely
as a result thereof or as a result of such transactions in conjunction with any
other events will be an "excess parachute payment" within the meaning of Section
280G of the Code.

                  (g) Except as provided in Section 4.09(g) of the Parent
Disclosure Schedule or as otherwise required by Law, no Parent Benefit Plan
provides retiree medical or retiree life insurance benefits to any person.

                  SECTION 4.10. Accounting and Tax Matters. (a) Except as
disclosed in the Parent Reports, neither Parent nor, to the knowledge of Parent,
any of its affiliates has taken or agreed to take any action (other than actions
contemplated by this Agreement) that would prevent the Merger from qualifying
for "pooling of interests" accounting treatment under applicable United States
accounting rules, including, without limitation, applicable SEC accounting
standards, or would prevent the Merger from constituting a transaction
qualifying under Section 368(a) of the Code. Parent is not aware of any
agreement, plan or other circumstance that would prevent the Merger from so
qualifying under Section 368(a) of the Code.

                  (b) The representations and warranties made in Parent's letter
of compliance with pooling of interest criteria addressed to Coopers & Lybrand
("Coopers & Lybrand") are true as of the date hereof.

                  SECTION 4.11. Contracts; Parent Debt Instruments. Except as
disclosed in the Parent Reports or in Section 4.11(a) of the Parent Disclosure
Schedule, there is no contract or agreement that is material to the business,
financial condition or results of operations of Parent and the Parent
Subsidiaries taken as a whole (each, a "Parent Material Contract"). Except as
disclosed in the Parent Reports or in Section 4.11(b) of the Parent Disclosure
Schedule, neither the Parent nor any Parent Subsidiary is in violation of or in
default under (nor does there exist any condition which with the passage of time
or the giving of notice would cause such a violation of or default under) any
loan or credit agreement, note, bond, mortgage, indenture or lease, or any other
contract, agreement, arrangement or understanding

                                       33

to which it is a party or by which it or any of its properties or assets is
bound, except for violations or defaults that would not, individually or in the
aggregate, result in a Parent Material Adverse Effect. Set forth in Section
4.11(c) of the Parent Disclosure Schedule is a description of any material
changes to the amount and terms of the indebtedness of Parent and the Parent
Subsidiaries as described in the notes to the financial statements incorporated
in the Parent 1996 10-K.

                  SECTION 4.12. Litigation. Except as disclosed in the Parent
Reports or in Section 4.12 of the Parent Disclosure Schedule, there is no suit,
claim, action, proceeding or investigation pending or, to the knowledge of
Parent, threatened against Parent or any Parent Subsidiary before any
Governmental Entity that, individually or in the aggregate, is reasonably likely
to have a Parent Material Adverse Effect, and, except as disclosed to the
Company, to the knowledge of Parent, there are no existing facts or
circumstances that would be reasonably likely to result in such a suit, claim,
action, proceeding or investigation. Except as disclosed to the Company, Parent
is not aware of any facts or circumstances which would result in the denial of
insurance coverage under policies issued to Parent and the Parent Subsidiaries
in respect of such suits, claims, actions, proceedings and investigations,
except in any case as would not, individually or in the aggregate, have a Parent
Material Adverse Effect. Except as disclosed in the Parent Reports or in Section
4.12 of the Parent Disclosure Schedule, neither Parent nor any Parent Subsidiary
is subject to any outstanding order, writ, injunction or decree which, insofar
as can be reasonably foreseen, individually or in the aggregate, would have a
Parent Material Adverse Effect.

                  SECTION 4.13. Environmental Matters. Except as disclosed in
the Parent Reports or in Section 4.13 of the Parent Disclosure Schedule or as
would not, individually or in the aggregate, have a Parent Material Adverse
Effect:

                  (a) Parent and the Parent Subsidiaries (i) are in compliance
         with all, and are not subject to any asserted liability or, to Parent's
         knowledge, any liability, in each case with respect to any, applicable
         Environmental Laws, (ii) hold or have applied for all Environmental
         Permits and (iii) are in compliance with their respective Environmental
         Permits;

                  (b) neither Parent nor any Parent Subsidiary has received any
         written notice, demand, letter, claim or request for information
         alleging that Parent or any of its Subsidiaries may be in violation of,
         or liable under, any Environmental Law;

                  (c) neither Parent nor any Parent Subsidiary (i) has entered
         into or agreed to any consent decree or order or is subject to any
         judgment, decree or judicial order relating to compliance with
         Environmental Laws, Environmental Permits or the

                                       34

         investigation, sampling, monitoring, treatment, remediation, removal or
         cleanup of Hazardous Materials and, to the knowledge of Parent, no
         investigation, litigation or other proceeding is pending or threatened
         in writing with respect thereto, or (ii) is an indemnitor in connection
         with any threatened or asserted claim by any third-party indemnitee for
         any liability under any Environmental Law or relating to any Hazardous
         Materials; and

                  (d) none of the real property owned or leased by Parent or any
         Parent Subsidiary is listed or, to the knowledge of the Company,
         proposed for listing on the "National Priorities List" under CERCLA, as
         updated through the date hereof, or any similar state or foreign list
         of sites requiring investigation or cleanup.

                  SECTION 4.14. Taxes. (a) Except as set forth in Section 4.14
of the Parent Disclosure Schedule and except for such matters that, individually
or in the aggregate, would not have a Parent Material Adverse Effect, (i) Parent
and each of the Parent Subsidiaries have timely filed or shall timely file all
returns and reports required to be filed by them with any taxing authority with
respect to Taxes for any period ending on or before the Effective Time, taking
into account any extension of time to file granted to or obtained on behalf of
Parent and the Parent Subsidiaries, (ii) all Taxes that are due prior to the
Effective Time have been paid or shall be paid on or before the applicable due
date, (iii) as of the date hereof, no deficiency for any amount of Tax has been
asserted or assessed by a taxing authority against Parent or any of the Parent
Subsidiaries and (iv) Parent and each of the Parent Subsidiaries have provided
adequate reserves in their financial statements for any Taxes that have not been
paid, whether or not shown as being due on any returns.

                  (b) To the best of Parent's knowledge, no Tax disputes or
audits are pending against, and no claims for Taxes have been received in
writing by or any of Parent Subsidiar ies, other than disputes, audits and
claims that are not reasonably likely to have a Parent Material Adverse Effect.

                  (c) There are no Tax liens upon any property or assets of
Parent or any of the Parent Subsidiaries except liens for current Taxes not yet
due and liens which have not had and are not reasonably likely to have a Parent
Material Adverse Effect.

                  SECTION 4.15. Pooling Affiliates. Section 4.15 of the Parent
Disclosure Schedule sets forth the names and addresses of those persons who are,
in Parent's reasonable judgment, a Pooling Affiliate of Parent.

                  SECTION 4.16. Non-Competition Agreements. Except as set forth
on Section 4.16 of the Parent Disclosure Schedule, neither Parent nor any Parent
Subsidiary is a party to




<PAGE>


                                       35

any agreement which purports to restrict or prohibit in any material respect
Parent and the Parent Subsidiaries collectively from, directly or indirectly,
engaging in any business involving the collection, interim storage, transfer,
recovery, processing, recycling, marketing or disposal of rubbish, garbage,
paper, textile wastes, chemical or hazardous wastes, liquid and any other wastes
services businesses currently engaged in by Parent or any corporations
affiliated with Parent. None of Parent's officers, directors or key employees is
a party to any agreement which, by virtue of such person's relationship with
Parent, restricts in any material respect Parent or any Parent Subsidiary or
affiliate from, directly or indirectly, engaging in any of the businesses
described above.

                  SECTION 4.17. Opinion of Financial Advisor. Donaldson, Lufkin
& Jenrette ("DLJ") has delivered to the board of directors of Parent its written
opinion to the effect that, as of the date of the opinion, the Exchange Ratio

commission in connection with the Merger based upon arrangements made by or on
behalf of Parent. Parent has heretofore made available to the Company complete
and correct copies of all agreements between Parent, on the one hand, and each
of DLJ, Relational and Lehman, on the other hand, pursuant to which such firm
would be entitled to any payment relating to the Merger.

with reputable insurers in such amounts and covering such risks as are in
accordance with normal industry practice for companies engaged in businesses
similar to that of Parent (taking into account the cost and availability of such

stock of Merger Sub will be owned directly by Parent. As of the Effective Time,
there will be no options, warrants or other rights, agreements, arrangements or
commitments to which Merger Sub is a party of any character relating to the
issued or unissued capital stock of, or other equity interests in, Merger Sub or
obligating Merger Sub to grant, issue or sell any shares of the capital stock
of, or other equity interests in, Merger Sub, by sale, lease, license or
otherwise.

other (and its officers, directors, employees, accountants, consultants, legal

access at reasonable times upon prior




<PAGE>


                                       42

notice to its and its subsidiaries' officers, employees, agents, properties,
offices and other facilities and to the books and records thereof, and (ii)
furnish promptly such information concerning its and its subsidiaries' business,
properties, contracts, assets, liabilities and personnel as the other party or
its Representatives may reasonably request. No investigation conducted pursuant
to this Section 5.05 shall affect or be deemed to modify any representation or
warranty made in this Agreement.

                  (b) The parties hereto shall comply with their respective
obligations under the Confidentiality Agreement dated January 26, 1998 (the
"Confidentiality Agreement") between Parent and the Company with respect to the

                  SECTION 5.06. No Solicitation of Transactions. (a) Each party
to this Agreement shall not, directly or indirectly, and shall instruct its
officers, directors, employees, subsidiaries, agents or advisors or other
representatives (including, without limitation, any investment banker, attorney
or accountant retained by it), not to, directly or indirectly, solicit, initiate
or knowingly encourage (including by way of furnishing nonpublic information),
or take any other action knowingly to facilitate, any inquiries or the making of
any proposal or offer (including, without limitation, any proposal or offer to
its stockholders) that constitutes, or may reasonably be expected to lead to,
any Competing Transaction, or enter into or maintain or continue discussions or
negotiate with any person in furtherance of such inquiries or to obtain a
Competing Transaction, or agree to or endorse any Competing Transaction, or
authorize or permit any of the officers, directors or employees of such party or
any of its subsidiaries, or any investment banker, financial advisor, attorney,
accountant or other representative retained by such party or any of such party's
subsidiaries, to take any such action; provided, however, that nothing contained
in this Section 5.06 shall prohibit the Board of Directors of Parent or the
Company from furnishing information to, or entering into discussions or
negotiations with, any person in connection with an unsolicited (from the date
of this Agreement) proposal by such person to acquire such party pursuant to a
merger, consolidation, share exchange, tender offer, exchange offer, business
combination or other similar transaction or to acquire all or substantially all
of the assets of such party or any of its subsidiaries, if, and only to the
extent that, (i) such Board of Directors, after consultation with outside legal
counsel (which may include its regularly engaged outside legal counsel),
determines in good faith that such action is required for such Board of
Directors to comply with its duties to its stockholders imposed by applicable
Law and (ii) prior to furnishing such information to, or entering into
discussions or negotiations with, such person, such party obtains from such
person an executed confidentiality agreement on terms no less favorable to the
Company or Parent, as the case may be, than those contained in the
Confidentiality Agreement. Each party hereto shall notify the other parties
hereto promptly if any proposal or offer, or any inquiry or contact with any
person with respect thereto, regarding a Competing




<PAGE>


                                       43

Transaction is made. Each party hereto immediately shall cease and cause to be
terminated all existing discussions or negotiations with any parties conducted
heretofore with respect to a Competing Transaction. Each party hereto agrees not
to release any third party from, or waive any provision of, any confidentiality
or standstill agreement to which it is a party. Notwithstanding the foregoing,
either party may enter into a confidentiality agreement containing a standstill
provision which permits, or waive compliance with any existing standstill
agreement in order to permit, a third party to make a confidential takeover
proposal to the Board of Directors which could reasonably be expected to result
in a Competing Transaction; provided, however, that either party may then
further waive compliance with a standstill agreement in order to permit a third
party to make such takeover proposal to such party's stockholders so as to
enable the Company or Parent to terminate this Agreement pursuant to the
provisions of Section 8.01(i) or (j), as the case may be; provided further that
nothing in this Section 5.06(a) shall affect the obligation of the Company or
Parent to pay the Company Termination Fee or the Parent Termination Fee (each as
hereinafter defined) pursuant to the terms of Section 8.05.

involving the Company or Parent, as the case may be (other than the Merger
contemplated by this Agreement): (i) a merger, consolidation, share exchange,
business combination or other similar transaction, (ii) any sale, lease,
exchange, transfer or other disposition of 25 percent or more of the assets of
such party and its subsidiaries, taken as a whole, or of assets of such party
and its subsidiaries generating 25 percent or more of such party's revenues or
operating income, or (iii) a tender offer or exchange offer for 25 percent or
more of the outstanding voting securities of such party.

                  SECTION 5.07. Pooling Matters. (a) From and after the date of
this Agreement, each of the parties hereto, and each of their respective
subsidiaries or other affiliates, shall take all reasonable actions necessary to
cause the Merger to be characterized as a pooling of interests for accounting
purposes.

                  (b) As soon as practicable following the effective time of the
merger of WMI Merger Sub, Inc. ("WMI Merger Sub"), a wholly owned subsidiary of
the Company, with and into Wheelabrator Technologies Inc. ("WTI") as
contemplated by the Agreement and Plan of Merger among the Company, WTI and WMI
Merger Sub, the Company shall take all actions necessary to cause the WTI
benefits plans set forth on Section 3.10 of the Company Disclosure Schedule (the
"WTI Stock Plans") to be amended so as to provide that the Company shall satisfy
any obligations it may have to repurchase a participant's exercisable but
unexercised options under such WTI Stock Plans by issuing to such participant
shares of the Company Common Stock, with a fair market value equal to the cash
that would otherwise have been payable thereunder.

statement on Form S-3 or other applicable form (the "S-3 Registration
Statement") to dispose of any "tainted shares" required to be disposed of prior
to the Effective Time (including those described in Section 3.10 of the Company
Disclosure Schedule, as well as any other shares of Company Common Stock
required to be disposed of prior to the Effective Time in furtherance of the
provisions of Section 5.07(a)); provided, however, that the terms and conditions
of any such disposition shall be reasonably acceptable to Parent (it being
understood and agreed that any sale of "tainted shares" at a customary discount
to the then-market price, less customary underwriters' discounts and
commissions, shall be reasonably acceptable to Parent). Parent will cooperate
with the Company in fulfilling the requirements of the S-3 Registration
Statement.

                  SECTION 5.08. Letters of Accountants. (a) Parent shall use all
reasonable efforts to cause to be delivered to the Company a "comfort" letter of
Coopers & Lybrand dated and delivered as of the date the Registration Statement
shall have become effective and a "bring-down comfort" letter of Coopers &
Lybrand dated and delivered as of the Effective Time. The Company shall use all
reasonable efforts to cause to be delivered to Parent a "comfort" letter of
Arthur Andersen dated and delivered as of the date the Registration Statement
shall have become effective and a "bring-down comfort" letter of Arthur Andersen
dated and delivered as of the Effective Time. Each such letter shall be
addressed to Parent and the Company, and shall be in form and substance
reasonably satisfactory to the recipient thereof and reasonably customary in
scope and substance for letters delivered by independent public accountants in
connection with mergers such as the one contemplated by this Agreement.

                  (b) Each of Parent and the Company shall use all reasonable
efforts to cause to be delivered to the other an opinion from Coopers & Lybrand
and Arthur Andersen, respectively, addressed to each of Parent and the Company
and dated as of the Closing Date, that the Merger will qualify for "pooling of
interests" accounting treatment under applicable United States accounting rules,
including, without limitation, applicable SEC accounting standards.

                  SECTION 5.09. Plan of Reorganization. This Agreement is
intended to constitute a "plan of reorganization" within the meaning of Section
1.368-2(g) of the income tax regulations promulgated under the Code. From and
after the date of this Agreement, each party hereto shall use all reasonable
efforts to cause the Merger to qualify, and shall not, without the prior written
consent of the other parties hereto, knowingly take any actions or cause any
actions to be taken which could prevent the Merger from qualifying as a
reorganization under the provisions of Section 368(a) of the Code.

                  SECTION 5.10. Subsequent Financial Statements. Prior to the
Effective Time, each of the Company and Parent (a) shall consult with the other
prior to making publicly available its financial results for any period and (b)
shall consult with the other prior to the filing of, and shall timely file with
the SEC, each Annual Report on Form 10-K, Quarterly Report on Form 10-Q and
Current Report on Form 8-K required to be filed by such party under the Exchange
Act and the rules and regulations promulgated thereunder and shall promptly
deliver to the other copies of each such report filed with the SEC. As of their
respective dates, none of such reports shall 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, in light of the circumstances under
which they were made, not misleading. The respective audited financial
statements and unaudited interim financial statements of each of the Company and
Parent, as the case may be, included in such reports shall fairly present the
financial position of such party and its Subsidiaries as at the dates thereof
and the results of their operations and cash flows for the periods then ended in
accordance with U.S. GAAP applied on a consistent basis and subject, in the case
of unaudited interim financial statements, to normal year-end adjustments.

                  SECTION 5.11. Control of Operations. Nothing contained in this
Agreement shall give Parent, directly or indirectly, the right to control or
direct the operations of the Company and the Company Subsidiaries prior to the
Effective Time. Nothing contained in this Agreement shall give the Company,
directly or indirectly, the right to control or direct the operations of Parent
and the Parent Subsidiaries prior to the Effective Time. Prior to the Effective
Time, each of Parent and the Company shall exercise, consistent with the terms
and conditions of this Agreement, complete control and supervision over its
respective operations.

                  SECTION 5.12. Further Action; Consents; Filings. (a) Upon the
terms and subject to the conditions hereof, each of the parties hereto shall use
all reasonable efforts to (i) take, or cause to be taken, all appropriate
action, and do, or cause to be done, all things necessary, proper or advisable
under applicable Law or otherwise to consummate and make effective the Merger,
(ii) obtain from Governmental Entities any consents, licenses, permits, waivers,
approvals, authorizations or orders required to be obtained or made by Parent,
the Company or the Surviving Corporation or any of their subsidiaries in
connection with the




<PAGE>


                                       46

authorization, execution and delivery of this Agreement and the consummation of
the Merger, including, but not limited to, actions with respect to Environmental
Permits, (iii) make all necessary filings, and thereafter make any other
required or appropriate submissions, with respect to this Agreement and the
Merger required under (A) the rules and regulations of the NYSE, (B) the
Securities Act, the Exchange Act and any other applicable federal or state
securities Laws, (C) the HSR Act and (D) any other applicable Law and (iv)
obtain any consents necessary such that the Merger will not constitute a change
of control, or any similar event, which constitutes a default (or an event which
with notice or lapse of time or both would become a default) under any material
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which the Company, Parent or any of their subsidiaries is a party.
The parties hereto shall cooperate and consult with each other in connection
with the making of all such filings, including by providing copies of all such
documents to the nonfiling parties and their advisors prior to filing, and any
comments of the nonfiling parties and their advisors shall be considered prior
to the filing of such document. No party shall consent to any voluntary
extension of any statutory deadline or waiting period or to any voluntary delay
of the consummation of the Merger at the behest of any Governmental Entity
without the consent and agreement of the other parties hereto.

                  (b) Without limiting the generality of the foregoing, and
subject to the following sentence, each of the parties hereto agrees, and shall
cause each of its respective Subsidiaries to cooperate and to use their
commercially reasonable efforts to obtain any government clearances required for
completion of the Merger (including though compliance with the HSR Act), to
respond to any government requests for information, and to contest and resist
any action, including any legislative, administrative or judicial action, and to
have vacated, lifted, reversed or overturned any Governmental Order (whether
temporary, preliminary or permanent) that restricts, prevents or prohibits the
consummation of the Merger, including, without limitation, by vigorously
pursuing all available avenues of administrative and judicial appeal and all
available legislative action. Each of the parties hereto also agrees to take or
cause to be taken the following actions: (i) provide promptly to Governmental
Entities with regulatory jurisdiction over enforcement of any applicable
antitrust laws ("Government Antitrust Entity") information and documents
requested by any Government Antitrust Entity or necessary, proper or advisable
to permit consummation of the transactions contemplated by this Agreement; (ii)
file any Notification and Report Form and related material required under the
HSR Act as soon as practicable after the date hereof, and thereafter use its
reasonable efforts to certify as soon as practicable its substantial compliance
with any requests for additional information or documentary material that may be
made under the HSR Act; (iii) deliver the proffer of Parent and the Company of
their willingness to (A) sell or otherwise dispose of, or hold separate and
agree to sell or otherwise dispose of, such assets, categories of assets or
businesses of Parent or Parent Subsidiaries or Company or Company Subsidiaries
(other than WME), as applicable, and (B) terminate such existing




<PAGE>


                                       47

relationships and contractual rights and obligations (and, in each case, to
enter into agreements with the relevant Government Antitrust Entity giving
effect thereto) in each case with respect to the foregoing clause (A) or (B), if
such action is necessary or reasonably advisable for the purpose of avoiding or
preventing any action by any Government Antitrust Entity which would restrain,
enjoin or otherwise prevent or materially delay consummation of the transactions
contemplated by this Agreement; provided, however, that no party shall be
required to take any actions described in this clause (iii) if such actions
would be reasonably likely, individually or in the aggregate, to have a Parent
Material Adverse Effect after giving effect to the Merger; and (iv) Parent or
the Company, as applicable, shall take promptly, in the event that any permanent
or preliminary injunction or other order is entered or becomes reasonably
foreseeable to be entered in any proceeding that would make consummation of the
transactions contemplated hereby in accordance with the terms of this Agreement
unlawful or that would prevent or delay consummation of the transactions
contemplated hereby, any and all steps (including the appeal thereof, the
posting of a bond or the taking of the steps contemplated by clause (iii) of
this subsection (b)) necessary to vacate, modify or suspend such injunction or
order so as to permit such consummation prior to the deadline specified in
Section 8.01(b). The parties hereto will consult and cooperate with one another,
and consider in good faith the views of one another, in connection with any
analyses, appearances, presentations, memoranda, briefs, arguments, opinions and
proposals made or submitted by or in behalf of any party hereto in connection
with proceedings under or relating to the HSR Act or any other federal, state or
foreign antitrust or fair trade law. The parties hereto will provide to the
other copies of all correspondence between it (or its advisors) and any
Government Antitrust Entity relating to this Agreement or any of the matters
described in this Section 5.12(b). The parties hereto agree that all material
telephonic calls and meetings with a Government Antitrust Entity regarding the
transactions contemplated hereby or any of the matters described in this Section
5.12(b) shall include representatives of each of Parent and the Company. Parent
shall coordinate and be the principal spokesperson in connection with any
proceedings or negotiations with any Governmental Entity relating to any of the
foregoing, provided that it shall afford the Company a reasonable opportunity to
participate therein.

                  SECTION 5.13. Stockholder Rights Plan. Notwithstanding the
limitations set forth in this Agreement with respect to the conduct of the
Company's or Parent's respective businesses prior to the Effective Time,
including the limitations set forth in Sections 5.01 and 5.02, either the
Company or Parent may, at any time prior to the Effective Time, take all actions
necessary to adopt and implement a stockholder rights plan, provided that the
terms of such stockholder rights plan shall specifically exclude the
consummation of the Merger as contemplated by this Agreement.

                  SECTION 5.14. Employee Benefit Plans. (a) Following the
Effective Time, Parent shall arrange for each employee of the Company or any
Company Subsidiary to




<PAGE>


                                       48

participate in any counterpart Parent Benefit Plans in accordance with the
eligibility criteria thereof, provided that (i) such participants shall receive
full credit for years of service with the Company or any Company Subsidiary (and
service otherwise credited by the Company or any Company Subsidiary) prior to
the Effective Time for all purposes for which such service was recognized under
the Company Benefit Plans including, but not limited to, eligibility to
participate, vesting, and, to the extent not duplicative of benefits received
under such Company Benefit Plan, the amount of benefits, (ii) such participants
shall participate in the Parent Benefit Plans on terms no less favorable than
those offered by Parent to similarly situated employees of Parent, and (iii)
Parent shall cause any and all pre-existing condition limitations, eligibility
waiting periods and evidence of insurability requirements under any group plans
to be waived with respect to such participants and their eligible dependents and
shall provide each such participant with credit for any co-payments and
deductibles paid prior to the Effective Time for purposes of satisfying any
applicable deductible, out-of-pocket, or similar requirements under any health
plans in which such participants are eligible to participate after the Effective
Time. Notwithstanding any of the foregoing to the contrary, none of the
provisions contained herein shall operate to duplicate any benefit provided to
any employee of the Company or the funding of any such benefit.

                  (b) Following the Effective Time, Parent shall cause the
Surviving Corporation to honor and perform, pursuant to their terms, all
employee benefit obligations to current and former employees and directors of
the Company under any Company Benefit Plans; provided, however, that nothing
contained herein shall limit any reserved right in any Company Benefit Plan to
amend, modify, suspend, revoke or terminate any such plan.

                  (c) Notwithstanding any of the foregoing to the contrary,
prior to the Effective Time, the Company shall take all necessary action to
terminate the Company Supplemental Executive Retirement Plan, as amended and
restated as of November 11, 1997 (the "SERP"). No further benefits shall accrue
under the SERP after its termination (except that participants shall be credited
with the maximum number of additional years of benefit service to which the
participant would be entitled under his or her employment agreement if his or
her employment terminated upon the termination of the SERP under circumstances
which would entitle him or her to severance or similar benefits under such
employment agreement) and all benefits thereunder shall be fully vested and paid
out on a present value basis, using the actuarial assumptions applicable to lump
sum payments under the Company's qualified defined benefit plan, effective as of
the date of termination of the SERP.

                  (d) To the extent that Parent elects to terminate after the
Effective Time any employee pension benefit plan maintained by the Company or
any Company Subsidiary which is a defined benefit plan, then all accrued
benefits thereunder shall be fully vested and the




<PAGE>


                                       49

accrued benefits shall be paid as promptly as practicable to participants
thereunder who so elect in a lump sum payment.

                              ADDITIONAL AGREEMENTS

(a) As promptly as practicable after the execution of this Agreement, (i) Parent
and the Company shall jointly prepare and file with the SEC a joint proxy
statement with respect to the Merger relating to the special meeting of each of
the Company's stockholders (the "Company Stockholders' Meeting") and Parent's
stockholders (the "Parent Stockholders' Meeting" and, together with the Company
Stockholders' Meeting, the "Stockholders' Meetings") to be held in connection
with the Merger (together with any amendments thereto, the "Joint Proxy
Statement") and (ii) Parent shall prepare and file with the SEC a registration
statement on Form S-4 (together with all amendments thereto, the "Registration

issuance of Parent Common Stock to the Company's stockholders pursuant to the
Merger, in which the Joint Proxy Statement shall be included as a prospectus.
Copies of the Joint Proxy Statement shall be provided to the NYSE in accordance
with the rules of such exchange. Each of the parties hereto shall use all
reasonable efforts to cause the Registration Statement to become effective as
promptly as practicable, and, prior to the effective date of the Registration
Statement, the parties hereto shall take all action required under any
applicable Laws in connection with the issuance of shares of Parent Common Stock
pursuant to the Merger. Parent or the Company, as the case may be, shall furnish
all information concerning Parent or the Company as the other party may
reasonably request in connection with such actions and the preparation of the
Registration Statement and Joint Proxy Statement. As promptly as practicable
after the effective date of the Registration Statement, the Joint Proxy
Statement shall be mailed to the stockholders of Parent and the Company. Each of
the parties hereto shall cause the Joint Proxy Statement to comply as to form
and substance in all material respects with the applicable requirements of (i)
the Exchange Act, (ii) the NYSE, (iii) the Securities Act and (iv) the DGCL.

this Agreement; provided, however, that the Board of Directors of the Company
may, at any time prior to the Effective Time, withdraw, modify or change any
such recommendation to the extent that the Board of Directors of the Company
determines in good faith, after consultation with outside legal counsel (who may
be the Company's regularly engaged outside legal counsel), that such




<PAGE>


                                       50

withdrawal, modification or change of its recommendation is required by its
fiduciary duties to the Company's stockholders under applicable Law. In
addition, the Joint Proxy Statement shall include the opinion of Merrill Lynch
referred to in Section 3.17.

                  (ii) The Joint Proxy Statement shall include the approval of

                  (c) No amendment or supplement to the Joint Proxy Statement or
the Registration Statement shall be made without the prior review of Parent and
the Company, and any comments of Parent or the Company shall be considered prior
to filing such amendment or supplement, to the extent practicable. Each of the
parties hereto shall advise the other parties hereto, promptly after it receives
notice thereof, of the time when the Registration Statement has become effective
or any supplement or amendment has been filed, of the issuance of any stop
order, of the suspension of the qualification of the Parent Common Stock
issuable in connection with the Merger for offering or sale in any jurisdiction,
or of any request by the SEC or the NYSE for amendment of the Joint Proxy
Statement or the Registration Statement or comments thereon and responses
thereto or requests by the SEC for additional information.

                  (d) The information supplied by the Company for inclusion in
the Registration Statement and the Joint Proxy Statement shall not, at (i) the
time the Registration Statement is filed with the SEC, (ii) if different, the
time the Registration Statement is declared effective, (iii) the time the Joint
Proxy Statement (or any amendment thereof or supplement thereto) is first mailed
to the stockholders of the Company and Parent, (iv) the time of the Company
Stockholders' Meeting, (v) the time of the Parent Stockholders' Meeting and (vi)
the Effective Time, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to

made, not misleading. If at any time prior to the Effective Time any event or
circumstance relating to the Company or any Company Subsidiary, or their
respective officers or directors, should be discovered by the Company that
should be set forth in an amendment or a supplement to the Registration
Statement or Joint Proxy Statement, the Company shall promptly inform Parent.

connection with the Merger will comply as

the DGCL, the Securities Act and the Exchange Act.

                  (e) The information supplied by Parent for inclusion in the
Registration Statement and the Joint Proxy Statement shall not, at (i) the time

the Registration Statement is declared effective, (iii) the time the Joint Proxy
Statement (or any amendment thereof or supplement thereto) is first mailed to
the stockholders of Parent and the Company, (iv) the time of the Company
Stockholders' Meeting, (v) the time of the Parent Stockholders' Meeting and (vi)
the Effective Time, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading. If, at any time prior to the Effective Time, any event or
circumstance relating to Parent or any Parent Subsidiary, or their respective
officers or directors, should be discovered by Parent that should be set forth
in an amendment or a supplement to the Registration Statement or Joint Proxy
Statement, Parent shall promptly inform the Company. All documents that Parent
is responsible for filing with the SEC in connection with the Merger will comply
as to form in all material respects with the applicable requirements of the
NYSE, the DGCL, the Securities Act and the Exchange Act.

                  SECTION 6.02. Stockholders' Meetings. The Company shall call
and hold the Company Stockholders' Meeting, and Parent shall call and hold the
Parent Stockholders' Meeting, in each case as promptly as practicable, for the
purpose, in the case of the Company Stockholders' Meeting, of voting upon the
adoption of this Agreement and the Merger contemplated hereby, and, in the case
of the Parent Stockholders' Meeting, of voting upon the adoption of the
Certificate Amendment and the Share Issuance pursuant to the Joint Proxy
Statement, and each of Parent and the Company shall use its reasonable efforts
to hold the Stockholders' Meetings on the same day and as soon as practicable
after the date on which the Registration Statement becomes effective. The
Company shall use its reasonable efforts to solicit from its stockholders
proxies in favor of the adoption of this Agreement pursuant to the Joint Proxy
Statement and shall take all other action necessary or advisable to secure the
vote or consent of stockholders required by the DGCL or applicable stock
exchange requirements to obtain such approval, except to the extent that the
Board of Directors of the Company determines in good faith after consultation
with outside legal counsel (who may be the Company's regularly engaged outside
legal counsel) that the withdrawal, modification or change of its recommendation
is required by its fiduciary duties to the Company stockholders under applicable
Law. Parent shall use its reasonable efforts to solicit from its stockholders
proxies in favor of the Certificate Amendment and the Share Issuance
contemplated hereby pursuant to the Joint Proxy Statement, and shall take all
other action necessary or advisable to secure the vote or consent of
stockholders required by the DGCL or applicable stock exchange requirements to
obtain such approval, except to the extent that the Board of Directors of Parent




<PAGE>


                                       52

determines in good faith after consultation with outside legal counsel (who may
be Parent's regularly engaged outside legal counsel) that the withdrawal,
modification or change of its recommendation is required by its fiduciary duties
to Parent's stockholders under applicable Law. Each of the parties hereto,
subject to the exercise of their fiduciary duties to their respective
stockholders, as described in this Section 6.02, shall take all other action
necessary or, in the opinion of the other parties hereto, advisable to promptly
and expeditiously secure any vote or consent of stockholders required by
applicable Law and such party's Restated Certificate of Incorporation and Bylaws
to effect the Merger.

                  SECTION 6.03. Post-Merger Directors and Chief Executive
Officer of Parent. (a) The Board of Directors of Parent shall take such action
as may be necessary to cause Parent's Board of Directors immediately following
the Effective Time to be composed of fourteen members, and to cause seven
persons designated by the Board of Directors of the Company prior to the Closing
(the "Company Designees") to be elected to Parent's Board of Directors. In
furtherance thereof, Parent shall increase the size of its Board of Directors
and secure the resignations of such number of its incumbent directors as is
necessary to effectuate the foregoing sentence. To the extent practicable, the
Company Designees and the members of the Parent board of Directors designated by
Parent shall be equally distributed among the Parent's three classes of
directors at the Effective Time. All of the Company Designees shall serve in
accordance with the Restated Certificate of Incorporation and Bylaws of Parent
until their respective successors are duly elected or appointed and qualified.
The Board of Directors of Parent shall take such action as may be necessary to
cause Mr. Robert S. Miller to be named as the Non-Executive Chairman of the
Board of Parent for a 12-month term to begin immediately following the Effective
Time. Following the expiration of such term, Mr. John E. Drury shall be named as
the Chairman of the Board of Parent.

                  (b) The current Chief Executive Officer of Parent shall remain
as Chief Executive Officer of Parent following the Effective Time.

                  SECTION 6.04. Pooling Affiliates. (a) Not less than 45 days
prior to the Effective Time, the Company shall deliver to Parent a list of names
and addresses of those persons, in the Company's reasonable judgment, at the
record date for the Company Stockholders' Meeting, who were Pooling Affiliates
of the Company. The Company shall provide Parent such information and documents
as Parent shall reasonably request for purposes of reviewing such list. The
Company shall use its reasonable efforts to deliver or cause to be delivered to
Parent, prior to the Effective Time, an affiliate letter in the form attached
hereto as Exhibit 6.04(a) (the "Company Affiliate Letter"), executed by each of
the Pooling Affiliates of the Company identified in the above-referenced list.
The foregoing notwithstanding, Parent shall be entitled to place legends as
specified in the Company Affiliate Letter on the certificates evidencing any of
the Parent Common Stock to be received by (i) any Pooling Affiliate of the




<PAGE>


                                       53

Company or (ii) any person Parent reasonably identifies (by written notice to
the Company) as being a person who may be deemed an "affiliate" within the
meaning of Rule 145 of the rules and regulations of the Securities Act or
applicable SEC accounting releases with respect to pooling-of-interests
accounting treatment, pursuant to the terms of this Agreement, and to issue
appropriate stop transfer instructions to the transfer agent for the Parent
Common Stock, consistent with the terms of the Company Affiliate Letter,
regardless of whether such person has executed the Company Affiliate Letter and
regardless of whether such person's name and address appear on Section 3.15 of
the Company Disclosure Schedule.

                  (b) Not less than 45 days prior to the Effective Time, Parent
shall deliver to the Company a list of names and addresses of those persons who
were, in Parent's reasonable judgment, at the record date for the Parent
Stockholders' Meeting, Pooling Affiliates of Parent. Parent shall provide the
Company such information and documents as the Company shall reasonably request
for purposes of reviewing such list. Parent shall use its reasonable efforts to
deliver or cause to be delivered to the Company, prior to the Effective Time, an
affiliate letter in the form attached hereto as Exhibit 6.04(b) (the "Parent
Affiliate Letter"), executed by each of the Pooling Affiliates of Parent
identified in the above-referenced list.

                  SECTION 6.05. Assumption of Debt. With respect to the
Company's indebtedness identified on Section 6.05 of the Company Disclosure
Schedule issued by the Company under an indenture qualified under the Trust
Indenture Act of 1939 (the "Company Indentures"), if required by the Company
Indentures, the Surviving Corporation shall execute and deliver to the trustee
under each Company Indenture a supplemental indenture, in form satisfactory to
the trustee, expressly assuming the obligations of the Company with respect to
the due and punctual payment of the principal of (and premium, if any) and
interest on such indebtedness and the due and punctual performance of all the
terms, covenants and conditions of the Company Indentures to be kept or
performed by the Company, and shall deliver such supplemental indenture to the
trustee under each Company Indenture. Holders of the Company Subordinated Notes
who convert after the Effective Time shall be entitled to receive Parent Common
Stock based on a ratio determined in accordance with Section 2.01(a).

                  SECTION 6.06. Indemnification of Directors and Officers. (a)
Parent and Merger Sub agree that the indemnification obligations set forth in
the Company's Restated Certificate of Incorporation and Bylaws, in each case as
of the date of this Agreement, shall survive the Merger (and, prior to the
Effective Time, Parent shall cause the Certificate of Incorporation and Bylaws
of Merger Sub to reflect such provisions) and shall not be amended, repealed or
otherwise modified for a period of six years after the Effective Time in any
manner that would adversely affect the rights thereunder of the individuals who
on or prior to the Effective Time were directors, officers, employees or agents
of the Company or the Company Subsidiaries.




<PAGE>


                                       54

                  (b) The Company shall, to the fullest extent permitted under
applicable Law and regardless of whether the Merger becomes effective, indemnify
and hold harmless, and, after the Effective Time, the Surviving Corporation
shall, to the fullest extent permitted under applicable Law, indemnify and hold
harmless, each present and former director, officer, trustee, fiduciary,
employee or agent of the Company and each Company Subsidiary and each such
person who served at the request of the Company or any Company Subsidiary as a
director, officer, trustee, partner, fiduciary, employee or agent of another
corporation, partnership, joint venture, trust, pension or other employee
benefit plan or enterprise (collectively, the "Indemnified Parties") against all
costs and expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages, liabilities and settlement amounts paid in connection
with any claim, action, suit, proceeding or investigation (whether arising
before or after the Effective Time), whether civil, administrative or
investigative, arising out of or pertaining to any action or omission in their
capacity as an officer or director, in each case occurring before the Effective
Time (including the transactions contemplated by this Agreement). Without
limiting the foregoing, in the event of any such claim, action, suit, proceeding
or investigation, the Company or the Surviving Corporation, as the case may be,
shall pay the fees and expenses of counsel selected by any Indemnified Party,

Corporation, as the case may be, promptly after statements therefor are received
(unless the Surviving Corporation shall elect to defend such action).

                  (c) For six years from the Effective Time, the Surviving
Corporation shall provide (to the extent available in the market) to the
Company's current directors and officers liability insurance protection of the
same kind and scope as that provided by the Company's directors' and officers'
liability insurance policies (copies of which have been made available to
Parent); provided, however, that in no event shall the Surviving Corporation be
required to expend more than 200% of the current amount expended by the Company
(the "Insurance Amount") to maintain or procure insurance coverage pursuant
hereto and further provided that if the Surviving Corporation is unable to
maintain or obtain the insurance called for by this Section 6.06(c), it shall
use its best efforts to obtain as much comparable insurance as is available for
the Insurance Amount.

                  (d) Following the Effective Time, Parent will fully guaranty
the prompt payment and performance of all obligations of the Surviving
Corporation pursuant to this Section 6.06 and under any and all director and
officer indemnification agreements entered into by the Company and/or any
Company Subsidiary.

                  (e) The obligations of the Company, the Surviving Corporation,
and Parent under this Section 6.06 shall not be terminated or modified in such a
manner as to adversely

affect any Indemnified Party without the consent of such affected party (it
being expressly agreed that each such party shall be a third-party beneficiary
of this Section 6.06).

                  (f) The rights of an Indemnified Party to indemnification and
advancement of expenses under this Section 6.06 shall not be deemed exclusive of
any other rights which the Indemnified Party may at any time be entitled to
under applicable Law, any charter or bylaw provision, any agreement, vote of
stockholders, resolution of disinterested directors or otherwise.

                  SECTION 6.07. No Shelf Registration. Parent shall not be
required to amend or maintain the effectiveness of the Registration Statement
for the purpose of permitting resale of the shares of Parent Common Stock

the Company within the meaning of Rule 145 promulgated under the Securities Act.

                  SECTION 6.08. Public Announcements. The initial press release
concerning the Merger shall be a joint press release and, thereafter, Parent and
the Company shall consult with each other before issuing any press release or
otherwise making any public statements with respect to this Agreement or the
Merger and shall not issue any such press release or make any such public
statement without the prior written approval of the other, except to the extent
required by applicable Law or the requirements of the NYSE, in which case the
issuing party shall use its reasonable efforts to consult with the other party
before issuing any such release or making any such public statement.

                  SECTION 6.09. Parent Restated Certificate of Incorporation. As
of the Effective Time, Parent shall cause its Restated Certificate of
Incorporation to be amended to reflect the Certificate Amendment.

hereto shall use its reasonable efforts to obtain, prior to the Effective Time,

issuance, of the shares of Parent Common Stock issuable to the Company's
stockholders in the Merger and upon the exercise of options pursuant to Section
2.04 hereof.

                  SECTION 6.11. Blue Sky. Each of the parties hereto shall use
all reasonable efforts to obtain prior to the Effective Time all necessary blue

                  SECTION 7.02. Conditions to the Obligations of the Company.

applicable Law, waiver of the following further conditions:

                  (a) each of the representations and warranties of Parent
         contained in this Agreement that is qualified by materiality shall be
         true and correct on and as of the Effective Time as if made at and as
         of the Effective Time (other than representations and warranties which
         address matters only as of a certain date which shall be true and
         correct as of such certain date) and each of the representations and
         warranties that is not so qualified shall be true and correct in all
         material respects on and as of the Effective Time as if made at and as
         of the Effective Time (other than representations and warranties which
         address matters only as of a certain date which shall be true and
         correct in all material respects as of such certain date), in each case
         except as contemplated or permitted by this Agreement, and the Company

         Chief Financial Officer of Parent to such effect;

                  (b) Parent shall have performed or complied in all material
         respects with all material agreements and covenants required by this
         Agreement to be performed or complied with by it on or prior to the

         reasonably satisfactory to the Company, based upon facts,
         representations and assumptions set forth in such opinion which are
         consistent with the state of facts existing at the Effective Time, to
         the effect that (i) the Merger will be treated for federal income tax
         purposes as a reorganization




<PAGE>


                                       58

         reorganization, (ii) no gain or loss will be recognized by Parent,
         Merger Sub or the Company as a result of the Merger, and (iii) no gain
         or loss will be recognized by the stockholders of the Company who
         exchange their Company Common Stock solely for Parent Common Stock
         pursuant to the Merger (except with respect to cash received in lieu of
         a fractional share interest). In rendering such opinion, counsel may
         require and rely upon representations contained in certificates of
         officers of Parent and the Company; and

                  (e) Parent shall have taken all action necessary to cause the
         Company Designees to become members of the Parent Board of Directors,
         and Mr. Robert S. Miller to be elected Chairman of the Board of Parent,
         in each case as of the Effective Time, as contemplated by Section 6.03.

                  SECTION 7.03. Conditions to the Obligations of Parent. The

         contained in this Agreement that is qualified by materiality shall be
         true and correct on and as of the Effective Time as if made at and as
         of the Effective Time (other than representations and warranties which
         address matters only as of a certain date which shall be true and
         correct as of such certain date) and each of the representations and
         warranties that is not so qualified shall be true and correct in all
         material respects on and as of the Effective Time as if made on and as
         of such date (other than representations and warranties which address
         matters only as of a certain date which shall be true and correct in
         all material respects as of such certain date), in each case except as
         contemplated or permitted by this Agreement, and Parent shall have
         received a certificate of the Chairman or President and Chief Financial
         Officer of the Company to such effect;

                  (b) the Company shall have performed or complied in all
         material respects with all material agreements and covenants required
         by this Agreement to be performed or complied with by it on or prior to
         the Effective Time and Parent shall have received a certificate of the
         Chairman or President and Chief Financial Officer of the Company to
         that effect;

                  (c) except as set forth on Section 3.08 of the Company
         Disclosure Schedule, no event or events shall have occurred or be
         reasonably likely to occur which, individually or in the aggregate,
         shall have had, or could reasonably be expected to have, a Company
         Material Adverse Effect, it being understood that for purposes of

                                       59

         determining whether a Company Material Adverse Effect shall have
         occurred on the assets, liabilities, financial condition or results of
         operations of the Company and the Company Subsidiaries taken as a
         whole, actual amounts as at any date of determination or for any period
         of determination shall be compared, to the extent practicable, to the
         corresponding amounts included in the Company's 1998 business plan
         included in Section 3.08 of the Company Disclosure Schedule; and

                  (d) Parent shall have received the opinion of Shearman &
         Sterling, in form and substance reasonably satisfactory to Parent,
         based upon facts, representations and assumptions set forth in such
         opinion which are consistent with the state of facts existing at the
         Effective Time, to the effect that (i) the Merger will be treated for
         federal income tax purposes as a reorganization qualifying under the
         provisions of Section 368(a) of the Code, and Parent, Merger Sub and
         the Company will each be a party to the reorganization, (ii) no gain or
         loss will be recognized by Parent, Merger Sub or the Company as a
         result of the Merger, and (iii) no gain or loss will be recognized by
         the stockholders of the Company who exchange their Company Common Stock
         solely for Parent Common Stock pursuant to the Merger (except with
         respect to cash received in lieu of a fractional share interest). In
         rendering such opinion, counsel may require and rely upon
         representations contained in certificates of officers of Parent and the
         Company.

                                  ARTICLE VIII

                        TERMINATION, AMENDMENT AND WAIVER

                  SECTION 8.01. Termination. This Agreement may be terminated
and the Merger may be abandoned at any time prior to the Effective Time,
notwithstanding any requisite adoption of this Agreement, as follows:

                  (a) by mutual written consent duly authorized by the Boards of
         Directors of each of Parent and the Company;

                  (b) by either Parent or the Company, if the Effective Time
         shall not have occurred on or before October 31, 1998; provided,
         however, that the right to terminate this Agreement under this Section
         8.01(b) shall not be available to any party whose failure to fulfill
         any obligation under this Agreement shall have caused, or resulted in,
         the failure of the Effective Time to occur on or before such date;
         provided further that this Agreement may be extended not more than 60
         days by Parent or the Company by written notice to the other party if
         the Merger shall not have been consummated as a direct result of (i)
         the Company or Parent having failed to receive all regulatory




<PAGE>


                                       60

         approvals or consents required to be obtained by the Company or Parent
         with respect to the Merger in order to satisfy the condition set forth
         in Section 7.01(e) or (ii) the existence of litigation or any
         governmental proceeding seeking to prevent or prohibit consummation of
         the Merger;

                  (c) by either Parent or the Company, if any Governmental
         Order, writ, injunction or decree preventing the consummation of the
         Merger shall have been entered by any court of competent jurisdiction
         and shall have become final and nonappealable;

                  (d) by Parent, if (i) in accordance with the proviso to
         Section 6.01(b)(i), the Board of Directors of the Company withdraws,
         modifies or changes its recommendation of this Agreement and the Merger
         in a manner adverse to Parent or its stockholders or shall have
         resolved to do so, or if the Board of Directors of the Company shall
         have refused to affirm its recommendation of this Agreement and the
         Merger as promptly as practicable (but in any event within three
         business days) after receipt of any request by Parent, (ii) the Board
         of Directors of the Company shall have recommended to the stockholders
         of the Company a Competing Transaction or shall have resolved to do so
         or (iii) a tender offer or exchange offer for 25 percent or more of the
         outstanding shares of capital stock of the Company is commenced and the
         Board of Directors of the Company fails to recommend against acceptance
         of such tender offer or exchange offer by its stockholders (including
         by taking no position with respect to the acceptance of such tender
         offer or exchange offer by its stockholders);

                  (e) by the Company, if (i) in accordance with the proviso to
         Section 6.01(b)(ii), the Board of Directors of Parent withdraws,
         modifies or changes its recommendation of this Agreement and the Merger
         in a manner adverse to the Company or its stockholders or shall have
         resolved to do so, or if the Board of Directors of Parent shall have
         refused to affirm its recommendation of this Agreement and the Merger
         as promptly as practicable (but in any event within three business
         days) after receipt of any request by the Company, (ii) the Board of
         Directors of Parent shall have recommended to the stockholders of
         Parent a Competing Transaction or shall have resolved to do so or (iii)
         a tender offer or exchange offer for 25 percent or more of the
         outstanding shares of capital stock of Parent is commenced and the
         Board of Directors of Parent fails to recommend against acceptance of
         such tender offer or exchange offer by its stockholders (including by
         taking no position with respect to the acceptance of such tender offer
         or exchange offer by its stockholders);

                  (f) by Parent or the Company, (i) if this Agreement shall fail
         to receive the requisite votes for adoption at the Company
         Stockholders' Meeting or any adjournment




<PAGE>


                                       61

         or postponement thereof or (ii) if the Share Issuance or the
         Certificate Amendment shall fail to receive the requisite votes for
         approval at the Parent Stockholders' Meeting or any adjournment or
         postponement thereof;

                  (g) by Parent, upon a breach of any representation, warranty,
         covenant or agreement on the part of the Company set forth in this
         Agreement, or if any representation or warranty of the Company shall
         have become untrue, in either case such that the conditions set forth
         in Section 7.03 would not be satisfied (a "Terminating Company
         Breach"); provided, however, that, if such Terminating Company Breach
         is curable by the Company through the exercise of its reasonable
         efforts and for so long as the Company continues to exercise such
         reasonable efforts, Parent may not terminate this Agreement under this
         Section 8.01(g); and provided further that the preceding proviso shall
         not in any event be deemed to extend any date set forth in paragraph
         (b) of this Section 8.01;

                  (h) by the Company, upon breach of any representation,
         warranty, covenant or agreement on the part of Parent set forth in this
         Agreement, or if any representation or warranty of Parent shall have
         become untrue, in either case such that the conditions set forth in
         Section 7.02 would not be satisfied (a "Terminating Parent Breach");
         provided, however, that, if such Terminating Parent Breach is curable
         by Parent through the exercise of its reasonable efforts and for so
         long as Parent continues to exercise such reasonable efforts, the
         Company may not terminate this Agreement under this Section 8.01(h);
         and provided further that the preceding proviso shall not in any event
         be deemed to extend any date set forth in paragraph (b) of this Section
         8.01;

                  (i) by the Company, if the Board of Directors of the Company
         shall, following receipt of advice of outside legal counsel (who may be
         the Company's regularly engaged outside legal counsel) that failure to
         so terminate would be inconsistent with its duties to its stockholders
         under applicable Law, in good faith have withdrawn, modified or changed
         its recommendation of the adoption of this Agreement and the Merger in
         a manner adverse to Parent and, on or prior to such date, any person
         (other than Parent) shall have made a public announcement or otherwise
         communicated to the Company and its stockholders with respect to a
         Competing Transaction that, as determined by the Board of Directors of
         the Company after consultation with its outside legal counsel (who may
         be its regularly engaged outside legal counsel) and financial advisors,
         contains terms more favorable to the stockholders of the Company than
         those provided for in the Merger; provided, however, that the Company
         may not terminate this Agreement pursuant to this Section 8.01(i) until
         three business days have elapsed following delivery to Parent of
         written notice of such determination of the Company (which written
         notice shall inform Parent of the material terms and conditions of the




<PAGE>


                                       62

         Competing Transaction); provided further, that such termination under
         this Section 8.01(i) shall not be effective until the Company has made
         payment to Parent of the amounts required to be paid pursuant to
         Section 8.05(b); or

                  (j) by Parent, if the Board of Directors of Parent shall,
         following receipt of advice of outside legal counsel (who may be
         Parent's regularly engaged outside legal counsel) that failure to so
         terminate would be inconsistent with its duties to its stockholders
         under applicable Law, in good faith have withdrawn, modified or changed
         its recommendation of the approval of this Agreement and the Merger in
         a manner adverse to the Company and, on or prior to such date, any
         person (other than the Company) shall have made a public announcement
         or otherwise communicated to Parent and its stockholders with respect
         to a Competing Transaction that, as determined by the Board of
         Directors of Parent after consultation with its outside legal counsel
         (who may be its regularly engaged outside legal counsel) and financial
         advisors, contains terms more favorable to the stockholders of Parent
         than those provided for in the Merger; provided, however, that Parent
         may not terminate this Agreement pursuant to this subsection (j) until
         three business days have elapsed following delivery to the Company of
         written notice of such determination of Parent (which written notice
         shall inform the Company of the material terms and conditions of the
         Competing Transaction); provided further, that such termination under
         this Section 8.01(j) shall not be effective until Parent has made
         payment to the Company of the amounts required to be paid pursuant to
         Section 8.05(c).

                  SECTION 8.02. Effect of Termination. Except as provided in
Section 9.01, in the event of termination of this Agreement pursuant to Section
8.01, this Agreement shall forthwith become void, there shall be no liability
under this Agreement on the part of Parent or the Company or any of their
respective officers or directors, and all rights and obligations of each party
hereto shall cease, subject to the remedies of the parties hereto set forth in
Section 8.05(b) through and including (f); provided, however, that nothing
herein shall relieve any party hereto from liability for the willful or
intentional breach of any of its representations and warranties or the willful
or intentional breach of any of its covenants or agreements set forth in this
Agreement; provided further, that the Confidentiality Agreement shall survive
any termination of this Agreement.

                  SECTION 8.03. Amendment. This Agreement may be amended by the
parties hereto by action taken by or on behalf of their respective Boards of

                        FORM OF COMPANY AFFILIATE LETTER


USA Waste Services, Inc.
1001 Fannin Street, Suite 4000
Houston, TX 77002

Waste Management, Inc.
3003 Butterfield Road
Oak Brook, IL 60523


Ladies and Gentlemen:

                  I have been advised that as of the date of this letter I may
be deemed to be an "affiliate" of Waste Management, Inc., a Delaware corporation
("Company"), as the term "affiliate" is (i) defined for purposes of paragraphs
(c) and (d) of Rule 145 of the rules and regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"), and/or (ii) used in and for
purposes of Accounting Series Releases 130 and 135, as amended, of the
Commission. Pursuant to the terms of the Agreement and Plan of Merger, dated as
of March 10, 1998 (the "Agreement"), among USA Waste Services, Inc. ("Parent"),
the Company and Dome Merger Subsidiary, Inc., a Delaware corporation and a
wholly owned subsidiary of Parent ("Merger Sub"), Merger Sub shall be merged
with and into the Company (the "Merger"), and the stockholders of the Company
shall receive shares of common stock, par value $.01 per share, of Parent
("Parent Common Stock"), in exchange for shares of common stock, par value $1.00
per share, of the Company (the "Company Common Stock").

                  As a result of the Merger, I may receive shares of Parent
Common Stock in exchange for shares (or upon exercise of options for shares or
upon the exercise by me of rights under certain option plans of the Company that
become exercisable upon the consummation of the Merger) owned by me of Company
Common Stock ("Parent Securities").

                  I represent, warrant and covenant to Parent that in the event
I receive any shares of Parent Securities as a result of the Merger:

                           A. I shall not make any sale, transfer or other
         disposition of Parent Securities in violation of the Act or the Rules
         and Regulations.

                                        2

                           B. I have carefully read this letter and the
         Agreement and discussed the requirements of such documents and other
         applicable limitations upon my ability to sell, transfer or otherwise
         dispose of Parent Securities to the extent I felt necessary, with my
         counsel or counsel for the Company.

                           C. I have been advised that the issuance of Parent
         Securities to me pursuant to the Merger shall be registered with the
         Securities and Exchange Commission (the "Commission") under the Act on
         a Registration Statement on Form S- 4. However, I have also been
         advised that, since (a) at the time the Merger shall be submitted for a
         vote of the stockholders of the Company, I may be deemed to be an
         affiliate of the Company and (b) the distribution by me of Parent
         Securities has not been registered under the Act, I may not sell,
         transfer or otherwise dispose of Parent Securities issued to me in the
         Merger unless (i) such sale, transfer or other disposition is made in

                           F. I also understand that, unless the sale or
         transfer by me of Parent Securities has been registered under the Act
         or is a sale made in conformity with the provisions of Rule 145, Parent

                           G. I further represent to, and covenant with, Parent
         that to the extent the consummation of the Merger results in a "change
         in control" pursuant to any option plan of the Company and, as a result
         thereof, I exercise my right to require Parent to repurchase my
         outstanding options thereunder, I will elect to receive Parent
         Securities as consideration for such repurchase, notwithstanding any

         from Parent (whether as the result of Parent's sale, on my behalf, of
         Parent Securities issued to me or otherwise).

                           H. I further represent to, and covenant with, Parent
         that I will not sell, transfer or otherwise dispose of, or execute any

                  WASTE MANAGEMENT AND USA WASTE AGREE TO MERGE
                  ---------------------------------------------

     -- Transaction Expected To Be Accretive To Both Companies' Shareholders
                      And To Accelerate Earnings Growth --

                    -- Operating Earnings Of Combined Company
                 Expected To Be $2.90 - $3.05 Per Share In 1999;
                   $3.55 - $3.70 Per Share In The Year 2000 --

OAK BROOK, ILLINOIS, AND HOUSTON, TEXAS, March 11, 1998 -- Waste
Management, Inc. (NYSE:  WMX) and USA Waste Services, Inc. (NYSE:  UW) today
announced that they have signed a definitive agreement to merge.

In the merger, which has been approved unanimously by the boards of both
companies, each share of Waste Management will be exchanged for 0.725 shares of
USA Waste common stock (or 345 million USA Waste shares), resulting in a total
of approximately 565 million outstanding shares for the combined company, after
adjusting for approximately 20 million pooling-related shares to be issued by
Waste Management prior to the merger. Waste Management shareholders will own
approximately 60 percent of the combined enterprise, which at yesterday's
closing stock prices would have an aggregate equity market capitalization in
excess of $20 billion. The transaction will be tax free to shareholders and is
intended to be accounted for as a pooling of interests.

The parties expect to achieve annual cost savings of at least $800 million
through operating synergies and enhanced efficiencies. Excluding costs directly
related to the merger, the transaction is expected to be accretive to both
companies' operating earnings for 1999 and the long term. Operating earnings for
the combined company in 1999 are currently expected to be in the range of $2.90
to $3.05 per share.

"In one stroke we are delivering to Waste Management and its shareholders the
ideal senior management team, while at the same time creating a new vehicle for
long-term growth," said Robert S. Miller, who has served as acting chairman and
chief executive officer of Waste Management, Inc. since October and was elected
chairman and chief executive officer on Tuesday. He will serve as non-executive
chairman of the combined company.

USA Waste Chairman and CEO John E. Drury, who will be CEO of the new company,
said, "This merger is about creating value for both companies' shareholders. An
essential result of the transaction is its expected accretion to USA Waste's
shareholders. We intend to move swiftly to apply our operating strategy to the
combined company. That strategy has allowed us to provide superior service to
our customers while maintaining the lowest costs and the highest profit margins
in the industry.

"The merger also represents an excellent platform from which to pursue future
growth," Mr. Drury added. "We anticipate the cost savings coupled with expected
strong revenue growth to allow the combined company's operating earnings to grow
at a rate in excess of 20 percent for the next several years."

The new company will benefit from a management and corporate governance
structure that melds the talents of the two organizations:

o        Mr. Miller will serve as non-executive chairman of the board of
         directors of the new company.

o        Mr. Drury will serve as chief executive officer and chairman of the
         board's executive committee.

o        USA Waste President and Chief Operating Officer Rodney R. Proto will
         serve as president and COO and as a director.

o        Earl E. DeFrates, USA Waste's chief financial officer, will serve as
         executive vice president and CFO.

o        Additional members of the new senior management team will be drawn from
         the best of both companies.

o        The new company will be governed by a board of directors consisting of
         an equal number of members designated by each company's current board.

o        Roderick M. Hills, a current member of Waste Management's board, will
         serve as chairman of the board's audit committee. Mr. Hills is a former
         chairman of the U.S. Securities and Exchange Commission.

o        Jerome B. York, a current member of USA Waste's board, will serve as
         chairman of a special integration committee overseeing achievement of
         cost savings and synergies. Mr. York is vice chairman of Tracinda
         Corporation and a former chief financial officer of IBM Corporation and
         Chrysler Corp.

o        USA Waste President and COO Rod Proto and Waste Management Executive
         Vice President and COO Joseph Holsten will serve as co-chairman of a
         special management committee designated to oversee the transition.

o        The new company will be named Waste Management, Inc. and will be based
         in Houston. It will also maintain offices in Oak Brook, Illinois.

"This transaction is driven by the tremendous cost savings available to the
combined company and the growth opportunity arising from creating the world's
largest solid waste company," Mr. Drury said. "These savings will come from
consolidating routes, eliminating duplicate facilities, utilizing transfer
stations and disposal facilities more cost-effectively, and streamlining
corporate and support functions.

"We are delighted to bring someone of Jerry York's talents to this process as
chairman of the board's Special Integration Committee," Mr. Drury continued.
"Realization of these savings, along with our growth strategy, will make the new
company a powerful cash-generating engine. These strong cash flows will give us
maximum flexibility for creating continuing shareholder value."

Mr. Miller stated, "After carefully reviewing a wide variety of strategic
alternatives available to Waste Management at this critical juncture in its
history, our board of directors determined that a strategic combination with USA
Waste is in the best interest of our shareholders. The transaction is expected
to be accretive to our shareholders in the near and long term.

Mr. Miller continued, "We have been looking for a dynamic, creative and
experienced CEO to lead our company. We found that person in John Drury. The
Waste Management board is confident that the combined company's corporate and
field management team -- drawing the best of the best from both companies --
will have the talent, commitment and enthusiasm needed to make this merger an
unqualified success.

"We are particularly impressed by the significant personal investments that John
Drury, his colleagues in senior management and the board of USA Waste have in
their company. They clearly have a strong incentive to deliver outstanding
results to the combined company's shareholders."

Mr. Drury added, "Waste Management has long been a leader in this industry and
is particularly distinguished by its dedicated and talented work force. I am
looking forward to the exciting task

                                        3

of combining the two companies' strengths to create the outstanding waste
services company of the next century."

Consummation of the transaction is subject to expiration or termination of the
applicable Hart-Scott-Rodino waiting period, approval of the merger by the
shareholders of each company, and other customary closing conditions. The
transaction is expected to be completed by the fall of 1998.

Donaldson, Lufkin & Jenrette served as financial adviser to USA Waste and
Merrill Lynch served as financial adviser to Waste Management.
