(b) Buyer acknowledges that for purposes of the BFI Plans, the consummation of the Acquisition will constitute a "Change in Control" of the Company. (c) Buyer currently intends to provide for a period of at least one year following the Closing Date, employee benefits and incentive compensation to active employees of the Company employed as of the Closing Date who are not covered by any collective bargaining agreement ("Company Employees") that are no less favorable in the aggregate than those provided to similarly situated employees of Buyer and its subsidiaries (excluding, however, severance payments for employees covered by paragraph (d) hereof).

Any severance pay to which a Company Employee is entitled hereunder shall be reduced by the severance pay such Company Employee receives from any other source. (e) Buyer and Seller each hereby acknowledge and agree that (i) at the Closing Date, each of the executives listed in Schedule 6.5(e) (which shall not include executives who are currently based at BFI's headquarters in Houston, Texas or at any of BFI's area business offices) will be deemed to have terminated his or her employment with the Company under circumstances which entitle such executive to the severance pay required by the contracts listed in Schedule 6.5(e); (ii) each such executive will become entitled to receive the severance pay (and other payments) required by such contracts upon a termination of employment following a "change of control" at the Closing Date; and (iii) any severance pay to which such executives are entitled shall be paid at the Closing Date or as soon as practicable after the Closing Date. Seller shall, prior to the Closing Date, use its reasonable efforts to cause BFI or the Company to take all action necessary such that each executive to whom this Section 6.5(e) applies shall be deemed to have consented to the payment of severance pay in accordance with this Section 6.5(e), notwithstanding any provision to the contrary in such contracts. The executives listed in Schedule 6.5(e) shall receive the coverage set forth in Section 6.5(f), subject to applicable law and to the extent permitted by applicable insurance policies. 16 18 (f) Buyer shall use reasonable efforts to cause any Company Employee (i) whose employment is involuntarily terminated without cause (including by reason of Constructive Discharge) during the 12 months following the Closing Date and (ii) who is age 50 or older on the date of termination to be provided with continued medical, dental and vision coverage for such Company Employee and his or her dependents from the date of termination until age 65 at such Company Employee's expense; provided, however, that the obligation of Buyer set forth in this Section 6.5(f) (x) shall cease if the Company Employee becomes eligible for coverage under any other employee benefit plan providing substantially similar benefits and (y) shall in any event be subject to applicable law. Coverage required by this Section 6.5(f) shall commence upon termination of the coverage required by Section 6.5(g). (g) Subject to applicable law and to the extent permitted by applicable insurance policies, Buyer shall cause any Company Employee whose employment is involuntarily terminated without cause (including by reason of Constructive Discharge) during the 12 months following the Closing Date to be provided with health insurance coverage at no cost to such Company Employee equal to the number of weeks based on the calculation of severance pay in Section 6.5(d) hereof, up to a maximum of 52 weeks. To the extent permitted by applicable existing insurance policies of Buyer, the COBRA continuation coverage period shall commence thereafter with coverage at Company Employee's cost. (h) For purposes of all employee benefit plans maintained by or contributed to by Buyer or its subsidiaries in which Company Employees participate, Buyer shall cause each such plan to treat the prior service with the Company or BFI of each Company Employee as service rendered to Buyer or its subsidiaries, as the case may be, for purposes of eligibility to participate, vesting, benefit accrual and levels of benefits under such plans; provided, that the foregoing shall not apply to the extent that its application would result in duplication of accrual of benefits or to newly established plans and programs for which prior service of Buyer employees is not taken into account. (i) Buyer shall (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Company Employees under any welfare benefits plans that such Company Employees may be eligible to participate in after the Closing Date, whether pursuant to the provisions of this Section 6.5 or otherwise, except to the extent that any Company Employees were subject to such preexisting conditions, exclusions and waiting periods under the Company plans, and (ii) provide each Company Employee with credit for any co-payments and deductibles paid prior to the Closing Date (in the calendar year of the Closing Date) in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans that such employees are eligible to participate in after the Closing Date.

(a) Subject to the terms and conditions of this Agreement, including Section 6.3, each of the parties hereto shall use all reasonable best efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement, including using its reasonable best efforts to obtain all necessary or appropriate waivers, consents or approvals of third parties required in order to preserve material contractual relationships of Buyer and the Company, all necessary or appropriate waivers, consents and approvals and SEC "no-action" letters to effect all necessary registrations, filings and submissions and to lift any injunction or other legal bar to the Acquisition (and, in such case, to proceed with the Acquisition as expeditiously as possible). In addition, subject to the terms and conditions herein provided and subject to the fiduciary duties of the respective boards of directors of Seller and Buyer, neither of the parties hereto shall knowingly take or cause to be taken any action (including, but not limited to, in the case of Buyer, (x) the incurrence of material debt financing, other than the Financing in connection with the Acquisition and related transactions and other than debt financing incurred in the ordinary course of business, and (y) the acquisition of businesses or assets) which would reasonably be expected to materially delay or prevent consummation of the Acquisition. Buyer shall use its reasonable best efforts to cause the satisfaction of any conditions to the receipt of funds arising from or related to the Financing Assurances. 18 20 (b) Without limitation of the foregoing, each of Buyer and Seller undertakes and agrees to file as soon as practicable, and in any event prior to 15 days after the date hereof, a Notification and Report Form under the HSR Act with the United States Federal Trade Commission (the "FTC") and the Antitrust Division of the United States Department of Justice (the "Antitrust Division"). Each of Buyer and Seller shall (i) respond as promptly as practicable to any inquiries received from the FTC or the Antitrust Division for additional information or documentation and to all inquiries and requests received from any State Attorney General or other governmental authority in connection with antitrust matters, and (ii) not extend any waiting period under the HSR Act or enter into any agreement with the FTC or the Antitrust Division not to consummate the transactions contemplated by this Agreement, except with the prior written consent of the other party hereto. Buyer shall use its reasonable best efforts to avoid or eliminate impediments under any antitrust, competition, or trade regulation law that may be asserted by the FTC, the Antitrust Division, any State Attorney General or any other governmental entity with respect to the Acquisition so as to enable the Closing Date to occur prior to September 15, 1999 (the "Outside Date"). Without limiting the foregoing, Buyer shall agree to negotiate the sale, divestiture or disposition of such assets or businesses of Buyer or, effective as of the Closing Date, the Company, or any of Buyer's subsidiaries, or agree to negotiate limits on its freedom of action with respect to any of the businesses, services or assets of Buyer, the Company or any of Buyer's subsidiaries, as reasonably may be required to avoid delaying the Closing Date beyond the Outside Date. At the request of Buyer, Seller shall use its reasonable efforts to cause the Company to agree to divest, hold separate or otherwise take or commit to take any action that limits its freedom of action with respect to, or its ability to retain, any of the businesses, services, or assets of the Company, provided that any such action may be conditioned upon the consummation of the Acquisition and the transactions contemplated hereby. Each party shall (i) promptly notify the other party of any written communication to that party from the FTC, the Antitrust Division, any State Attorney General or any other governmental entity and, subject to applicable law, permit the other party to review in advance any proposed written communication to any of the foregoing; (ii) not agree to participate in any substantive meeting or discussion with any governmental authority respect of any filings, investigation or inquiry concerning this Agreement or the Acquisition unless it consults with the other party in advance and, to the extent permitted by such governmental authority, gives the other party the opportunity to attend and participate thereat; and (iii) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their affiliates and their respective representatives on the one hand, and any government or regulatory authority or members or their respective staffs on the other hand, with respect to this Agreement and the Acquisition. If Buyer shall have complied with all of its obligations under this Section 6.10, but there is no action that Buyer or Seller can undertake or offer to undertake that would eliminate the impediment asserted by the FTC, Antitrust Division, or State Attorney General or other order in any suit or proceeding, in order for the Closing Date to occur prior to the applicable date specified in Section 8.1(ii), assuming all conditions other than those relating to such impediment or order have been satisfied or waived, then Buyer shall not be deemed to have breached its obligations under this Section 6.10. (c) In the event any litigation is commenced by any person or entity relating to the transactions contemplated by this Agreement, Buyer shall have the right, at its own expense, to participate therein, and Seller will not settle any such litigation without the consent of Buyer, which consent will not be unreasonably withheld. (d) In connection with the consummation of the Financing contemplated by the Financing Assurances, at the reasonable request of Buyer, Seller (i) agrees to enter into such agreements, to use reasonable best efforts to deliver such officers' certificates and opinions as are customary in financing of this type and as are, in the good faith determination of the persons executing such officers' certificates or opinions, accurate and (ii) will provide to the lenders who have issued financing commitments to Buyer for the Acquisition financial and other information in Seller's possession with respect to the Acquisition, use reasonable efforts to make the Company's senior officers available to assist such lenders, and otherwise cooperate in connection with the consummation of the Financing. (e) Buyer shall provide Seller any certificates from Buyer relating to the solvency and adequate capitalization of Buyer and Buyer's ability to pay its debts that are given to any banks, other lenders in 19 21 connection with the Financing or the independent evaluation firm as may be reasonably requested by Seller. Any such certificate, opinion or other statement will be provided to Seller at the time it is provided to such banks or other lenders. (f) At Buyer's request, Seller shall, at no additional expense to Seller, cause the BFI Medical Waste Assets to be transferred to two or more entities, including the Company, in which event all references in this Agreement to the "Company" shall include all such entities that hold the BFI Medical Waste Assets. (g) From and after the Closing Date, Seller will cooperate with Buyer in taking such actions as may be necessary to fully vest in the Company or in Buyer title to the assets that comprise the Business. Section 6.11 DIRECTORS' AND OFFICERS' INDEMNIFICATION. (a) The indemnification provisions of the certificate of incorporation and bylaws of the Company as in effect at the Closing Date shall not be amended, repealed or otherwise modified for a period of six years from the Closing Date in any manner that would adversely affect the rights thereunder of individuals who at the Closing Date were directors, officers, employees or agents of the Company. Buyer shall assume, be jointly and severally liable for, and honor, guaranty and stand surety for, and shall cause the Company to honor, in accordance with their respective terms each of the covenants contained in this Section 6.11 without limit as to time. (b) Without limiting Section 6.11(a), after the Closing Date, each of Buyer and the Company shall, to the fullest extent permitted under applicable law, indemnify and hold harmless, each present and former director, officer, employee and agent of the Company (each, together with such person's heirs, executors or administrators, an "Indemnified Party" and collectively, the "Indemnified Parties") against any costs or expenses (including attorneys' fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of, relating to or in connection with any action or omission occurring or alleged to occur prior to the Closing Date (including, without limitation, acts or omissions in connection with such persons serving as an officer, director or other fiduciary in any entity if such service was at the request or for the benefit of the Company) and the Acquisition and the other transactions contemplated by this Agreement or arising out of or pertaining to the transactions contemplated by this Agreement. In the event of any such actual or threatened claim, action, suit proceeding or investigation (whether arising before or after the Closing Date), (i) the Company or Buyer, as the case may be, shall pay the reasonable fees and expenses of counsel selected by the Indemnified Parties, which counsel shall be reasonably satisfactory to Buyer, promptly after statements therefor are received and shall pay all other reasonable expenses in advance of the final disposition of such action, (ii) Buyer and the Company will cooperate and use all reasonable efforts to assist in the vigorous defense of any such matter, and (iii) to the extent any determination is required to be made with respect to whether an Indemnified Party's conduct complies with the standards set forth under the Delaware Law and Buyer's or the Company's respective certificate of incorporation or bylaws, such determination shall be made by independent legal counsel acceptable to the Buyer or the Company, as the case may be, and the Indemnified Party; provided, however, that neither Buyer nor the Company shall be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld) and, provided further, that if Buyer or the Company advances or pays any amount to any person under this paragraph (b) and if it shall thereafter be finally determined by a court of competent jurisdiction that such person was not entitled to be indemnified hereunder for all or any portion of such amount, to the extent required by law, such person shall repay such amount or such portion thereof, as the case may be, to Buyer or the Company, as the case may be. The Indemnified Parties as a group may not retain more than one law firm to represent them with respect to each matter unless there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more Indemnified Parties. (c) In the event the Company or Buyer or any of their successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such 20 22 consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any person, then and in each such case, proper provisions shall be made so that the successors and assigns of the Company or Buyer shall assume the obligations of the Company or the Buyer, as the case may be, set forth in this Section 6.11. (d) Buyer shall pay all reasonable expenses, including reasonable attorneys' fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 6.11. (e) The rights of each Indemnified Party hereunder shall be in addition to, and not in limitation of, any other rights such Indemnified Party may have under the charter or bylaws of the Company, any indemnification agreement, under the Delaware Law or otherwise. The provisions of this Section 6.11 shall survive the consummation of the Acquisition and expressly are intended to benefit each of the Indemnified Parties. Section 6.12 SECTION 338(H)(10) ELECTION. Seller and Buyer each agree to make timely Section 338(h)(10) elections pursuant to Regulation 1.338(h)(10)-1(d) with respect to the acquisition of the Company Shares on Form 8023 and in accordance with the instructions to such Form. Seller agrees to report on its tax return the deemed sale gain resulting from such election in accordance with Code Section 338 and Regulation 1.338(h)(10)-1(e). Buyer shall submit to Seller for its review and approval a proposed valuation of the assets of the Company deemed to have been sold at least 120 days prior to the due date for the filing of any tax return reporting such deemed sale gain. The parties agree to negotiate in good faith such valuation. Buyer shall pay to Seller at the Closing an amount equal to the net increase in state income taxes payable by Seller by reason of the Section 338(h)(10) election or the transfers described in the recitals to this Agreement, as jointly determined for the parties by Arthur Andersen, LLP (for Seller) and Ernst & Young, LLP (for Buyer).

Notwithstanding the foregoing, Seller shall not be prohibited from acquiring any solid waste or other business (which is not primarily a medical waste business) or assets that include a medical waste operation, provided that during the five year term of the covenant not to compete, if Seller determines to divest any such medical waste operations, Seller offers to Buyer the first right to acquire the same on generally the same terms and under the same time parameters as established in the First Rights Agreement.
