W I T N E S S E T H: WHEREAS, the boards of directors of Parent and the Company have determined that it is consistent with and in furtherance of their respective long-term business strategies and fair to and in the best interests of their respective companies and stockholders to combine their respective businesses pursuant to the transaction set forth in this Agreement; WHEREAS, the board of directors of each of Parent, Merger Sub and the Company have approved and declared advisable the merger of Merger Sub with and into the Company (the "Merger"), upon the terms and subject to the conditions of this Agreement and in accordance with the General Corporation Law of the State of Delaware (the "DGCL"); WHEREAS, the board of directors of Parent has approved this Agreement and the Merger and the issuance of common stock, par value $.01 per share, of Parent ("Parent Common Stock"), and the amendments to the Restated Certificate of Incorporation of Parent, all as contemplated by this Agreement, and has recommended that the holders of Parent Common Stock vote to approve the issuance of Parent Common Stock and the amendments to the Restated Certificate of Incorporation of Parent as contemplated by this Agreement; WHEREAS, the board of directors of the Company has approved this Agreement and the Merger, as contemplated by this Agreement, and has recommended that the holders of common stock, par value $1.00 per share, of the Company ("Company Common Stock"), vote to adopt this Agreement and the terms of the Merger as contemplated by this Agreement; WHEREAS, the board of directors of Merger Sub has approved this Agreement and the Merger, as contemplated by this Agreement, and has recommended that its sole stockholder vote to adopt this Agreement and the terms of the Merger, and Parent, as the sole stockholder of Merger Sub, has adopted this Agreement and terms of the Merger, as contemplated by this Agreement; 2 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 THE MERGER 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 Effective Time (as defined below), Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation of the Merger as a wholly owned subsidiary of Parent (the "Surviving Corporation"). SECTION 1.02. Closing. Unless this Agreement shall have been terminated and the Merger herein contemplated shall have been abandoned pursuant to Section 8.01 and subject to the satisfaction or waiver of the conditions set forth in Article VII, the consummation of the Merger shall take place as promptly as practicable (and in any event within three business days) after 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 Avenue, New York, New York, unless another date, time or place is agreed to by Parent and the Company. 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 Delaware, in such form as required by, and executed in accordance with the 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"). 3 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, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation. SECTION 1.05. Certificate of Incorporation; Bylaws; Directors 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 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 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. 4 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 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 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 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; 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.

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.

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").

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(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 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 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.

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. 44 (c) The Company agrees that, at Parent's request, it shall cooperate with and assist Parent in conducting one or more registered exchange offers to exchange outstanding Company Stock Options for shares of Parent Common Stock as of the Effective Time. The Company shall furnish all information concerning the Company as Parent may reasonably request in connection with such exchange offer(s), including as may be necessary to comply with the applicable requirements of the Exchange Act, the Securities Act, the NYSE and the DGCL.

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. 45 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 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 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.

(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.

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 conformity with the volume and other limitations of Rule 145 promulgated by the Commission under the Act, (ii) such sale, transfer or other disposition has been registered under the Act or (iii) in the opinion of counsel reasonably acceptable to Parent, such sale, transfer or other disposition is otherwise exempt from registration under the Act. D. I understand that, except as provided in the Agreement, Parent is under no obligation to register the sale, transfer or other disposition of Parent Securities by me or on my behalf under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available. E. I also understand that stop transfer instructions will be given to Parent's transfer agents with respect to Parent Securities issued to me and that there will be placed on the certificates for Parent Securities issued to me, or any substitutions therefor, a legend stating in substance: "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED ________ BETWEEN THE REGISTERED HOLDER HEREOF AND USA WASTE SERVICES, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF USA WASTE SERVICES, INC." 3 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 reserves the right to put the following legend on the certificates issued to my transferee: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933." 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 ability I may have under such option plan to receive cash consideration 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 cashless exercise of stock options or warrants for, (i) any Company Common Stock during the 30 days immediately preceding the effective date of the Merger or (ii) any Parent Securities received by me in the Merger or any other shares of the capital stock of Parent or enter into any arrangement to reduce my risk relating to Company Common Stock or such Parent Securities until after such time as results covering at least 30 days of combined operations of Company and Parent have been published by Parent, in the form of a quarterly earnings report, an effective registration statement filed with the Commission, a report to the Commission on Form 10-K, 10-Q or 8-K, or any other public filing or announcement which includes such combined results of operations. Parent shall notify the "affiliates" of the publication of such results. 4 Execution of this letter should not be considered an admission on my part that I am an "affiliate" of the Company as described in the first paragraph of this letter, or as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.
