In the event that Purchaser shall object to the Preliminary Closing Balance Sheet, such statement shall include a detailed itemization of Purchaser's objections and its reasons therefor. Objections, if any, shall be limited to transactions occurring subsequent to June 30, 1997. If no such statement is delivered by Purchaser to Seller within the Review Period, Purchaser shall be deemed to have accepted the Preliminary Closing Balance Sheet. (iii) In the event that Purchaser shall accept or shall be deemed to have accepted the Preliminary Closing Balance sheet as prepared and delivered by Seller, the Preliminary Closing Balance Sheet shall constitute the Final Closing Balance Sheet for purposes of determining any adjustment to the Estimated Purchase Price. In the event, however, that Purchaser shall object to the Preliminary Closing Balance Sheet within the Review Period, Purchaser and Seller shall promptly meet and in good faith attempt to resolve such objections. Any such objections which cannot be resolved between Purchaser and Seller within thirty (30) days following Seller's receipt of Purchaser's statement of objections shall be resolved in accordance with the procedures set forth in Section 3.02(e). The Preliminary Closing Balance Sheet, as adjusted to reflect the adjustments agreed upon by the parties or determined in accordance with Section 3.02(e), shall constitute the Final Closing Balance Sheet for purposes of determining any adjustment to the Estimated Purchase Price. (c) ADJUSTMENT AND SETTLEMENT OF PURCHASE PRICE. In the event that the amount of the Closing Net Assets as finally determined is greater or less than the amount of the June 30 Net Assets, such excess or deficiency, as the case may be, shall be referred to as the "ADJUSTMENT." On the third business day following the date upon which the Final Closing Balance Sheet as provided for in Section 3.03(b)(iii) is determined, Purchaser shall pay to Seller (if the Closing Net Assets are greater than the June 30 Net Assets), or Seller shall pay to Purchaser (if the June 30 Net Assets are greater than the Closing Net Assets), the amount of the Adjustment. Payment of the Adjustment shall be made by wire transfer of immediately available United States funds. (d) ALLOCATION OF PURCHASE PRICE. The consideration given by Purchaser under this Agreement (including without limitation the payment of the Purchase Price and the assumption of the Assumed Liabilities) shall be allocated among the Assets in accordance with section 1060 of the Internal Revenue Code of 1986, as amended (the "CODE"), and the regulations under the Code. 11 A schedule setting forth such proposed allocations shall be prepared by Purchaser and delivered to the Selling Entities within one hundred twenty (120) days following the Closing Date. The determination of the amount of consideration paid by Purchaser, including the Assumed Liabilities, and its allocation as set forth on such schedule shall be reasonably determined by Purchaser and shall be reasonably satisfactory to the Selling Entities. Purchaser and the Selling Entities agree to make such allocation in filing their respective tax returns or declarations for applicable United States income tax purposes. (e) ACCOUNTING OBJECTIONS. Should the Selling Entities and Purchaser not be able to resolve such objections as may be raised with respect to the Preliminary Closing Balance Sheet, the Final Closing Balance Sheet or adjustments to the Estimated Purchase Price (collectively, the "ACCOUNTING OBJECTIONS"), the Accounting Objections shall be submitted to a binding arbitration to be conducted by AA which shall represent Seller and the independent public accounting firm of DT which shall represent Purchaser. Should AA and DT be unable to agree on the resolution of the Accounting Objections, after negotiating in good faith for a period of thirty (30) days, the same shall be submitted to Ernst & Young LLP for a binding resolution. The Selling Entities and Purchaser shall be responsible for the fees of their respective accounting firms. The fees of the third accounting firm, if one is required, shall be borne equally by the Selling Entities and Purchaser. 3.04 ASSUMPTION OF LIABILITIES.

Purchaser shall indemnify and hold harmless Selling Entities and their Affiliates from and against any liability resulting from, or obligations incurred under the Performance Bonds after the Closing Date. Purchaser shall pay Selling Entities for the cost of the Performance Bonds attributed to the period after Closing for which such Performance Bonds remain in force.

Contemporaneously with the delivery of the Preliminary Closing Balance Sheet, the Selling Entities shall deliver to Purchaser listings of such items updated through the Closing Date. During the ninety (90) day period following the Closing (the "COLLECTION PERIOD"), Purchaser shall use normal collection procedures (but in no event shall Purchaser be obligated to file or perfect any liens or file or prosecute any suit as part of its collection effort) to collect all invoice amounts, notes and drafts receivable, and unbilled receivable amounts and other receivable items in respect of the Business as of the Closing Date which are included in the Final Closing Balance Sheet (the "CLOSING DATE RECEIVABLES"). Any payments received by Purchaser from any person who is the account debtor on any of the Closing Date Receivables (a "CUSTOMER") shall be applied as specified by the Customer, unless (i) it is uncertain which invoice is being paid, or (ii) part of the invoice covers unbilled receivables. In either such case, payments shall be applied in the order of the oldest invoice or unbilled receivable first, unless Purchaser or the Selling Entities shall have received notice of a bona fide dispute with respect to such account. Each of the Selling Entities shall promptly remit to Purchaser any payments which it may receive in respect of any of the Closing Date Receivables. 13 Each of the Selling Entities grants to Purchaser the authority, coupled with an interest, to receive, endorse, cash, deposit, and receipt for any checks, drafts, documents and instruments evidencing Closing Date Receivables which are in the name of any of the Selling Entities. Purchaser shall make and keep detailed records of amounts collected in respect of the Closing Date Receivables until such time as any Uncollected Receivables are assigned to the Selling Entities pursuant to paragraph (b) below, and shall make such records available for review by the Selling Entities when a statement of Uncollected Receivables is delivered to the Selling Entities.

If Purchaser does not provide the Selling Entities with a list and description of Uncollected Receivables within thirty (30) days after expiration of the Collection Period, Purchaser may not demand that the Selling Entities repurchase the Uncollected Receivables or otherwise hold the Selling Entities responsible for nonpayment thereof and Purchaser shall have no other remedy against the Selling Entities with respect to the Uncollected Receivables.

Inc. ("Dillon Read") has been retained by Brown & Root, Inc. ("B&R") to explore the possible sale of its Environmental Services business (the "Environmental Business") principally operated by B&R's subsidiary, Halliburton NUS Corporation ("HNUS"). You have requested information concerning the Environmental Business in connection with your investigation. Dillon Read is furnishing to you oral and written information on behalf of B&R and HNUS, and may furnish additional information in the future, that B&R and HNUS consider confidential. By accepting such information, you agree that any information that may be furnished to you by officers, directors, employees, agents or financial advisors of B&R or HNUS will be kept confidential. In no event shall you use such information to the detriment of B&R nor HNUS. You agree to provide such material only to responsible officers, employees or agents (including your outside legal counsel, accountants, sources of financing and financial advisors) of your company hereinafter referred to as "Representatives" (all of whom shall be informed by you of this Agreement and shall agree to be bound by the terms hereof), for the exclusive purpose of evaluating a possible acquisition transaction, and you shall be responsible for compliance with the terms of this Agreement by all such persons to whom you provide such information. You agree not to make such material available to any other person or group as defined above for any other purpose whatsoever. You further agree that without B&R's prior written consent, you will not disclose to any person the fact that you have requested confidential information regarding the Environmental Business, or that discussions or negotiations are taking place concerning a possible acquisition transaction involving you and B&R and HNUS or the status thereof, unless, in the opinion of your counsel, such disclosure is required by the United States securities laws (in which case you shall notify B&R and its counsel prior to any disclosure you propose to make concerning the reasons for, and nature of, your proposed disclosure). In the event that you are requested in any proceeding to disclose any material concerning the Environmental Business, you will give B&R prompt notice of such request so that B&R may seek an appropriate protective order. If in the absence of a protective order you are nonetheless compelled to disclose material concerning the Environmental Business, you may disclose such information without liability hereunder; provided, however, that you give B&R written notice of the information to be disclosed as far in advance of its disclosure as is practicable and, upon B&R's request and at B&R's expense, use your best efforts to obtain assurances that confidential treatment will be accorded to such information. In the event that you do not make an acquisition proposal or offer, or an acquisition transaction does not proceed for any other reason, you agree upon the request of B&R or Dillon Read to return all information furnished to you and any copies thereof and to destroy any notes, extracts or analyses which are based upon or derived from such information. Your obligations under the Agreement shall survive the return or destruction of such information and shall expire on the third anniversary of the date of this Agreement. The foregoing restrictions with respect to information furnished to you shall not apply to any information which you demonstrate (i) becomes generally available to the public other than as a result of a disclosure by you or your representatives, (ii) was available to you on a non-confidential basis prior to its disclosure to you by B&R, HNUS or their representatives or (iii) becomes available to you on a non-confidential basis from a source other than B&R, HNUS or their representatives, which source was not itself bound by a confidentiality agreement with B&R, HNUS or their representatives. You further agree that for a period of two years from the date of this Agreement, your "Representatives" will not, without the prior written approval of HNUS or B&R, as applicable, directly or indirectly solicit for employment or hire any person who is now employed in an executive, managerial, marketing or technical role by HNUS or by B&R in the Environmental Business, who comes to your attention in connection with your evaluation of HNUS.

The following are the general terms and conditions under which the Selling Entities will provide Purchaser certain support, services and facilities ("Seller Services"). Seller Services will be provided in accordance with these general terms and conditions and in accordance with Exhibit A attached to and made a part of this Transition Agreement. SECTION 2 SELLER SERVICES 2.1 SELLER FACILITIES. As requested by Purchaser, the Selling Entities shall provide Purchaser with substantially the same use of owned real estate, leasehold interests, and the facilities thereon and the shared office equipment, furniture and supplies ("Seller Facilities") at the locations specified in Exhibit A as the Selling Entities made available to the Business immediately prior to the date hereof.

Subject to Section 2.2 below, Purchaser, with respect to its use of Seller Facilities, shall pay the applicable monthly rent for each of the Seller Facilities at the rate set forth in Exhibit A, which rates include normal utilities and taxes. Selling Entities' obligation to provide Purchaser the use of Seller Facilities shall terminate SIX (6) MONTHS after the Agreement Date. Purchaser shall leave the Seller Facilities in 2 substantially the same condition as existed on the date hereof with fair wear and tear excepted. 2.2 FREE RENTAL PERIOD. Purchaser shall not owe any rental on a facility listed in Exhibit A if Purchaser has removed all its property, equipment and personnel from such facility within thirty (30) days from the Agreement Date. For purposes of calculating time under this provision, the first day of the thirty (30) day period shall be deemed to be the day after the Agreement Date. If Purchaser does not vacate a facility within such thirty (30) day period, 3 Purchaser shall pay the applicable monthly rent for such facility but only for the period commencing on the thirty first (31st) day through the date the facility is vacated. 2.3 MISCELLANEOUS SERVICES. Selling Entities will provide such services as may be reasonably requested by Purchaser to permit Purchaser to continue operations relating to the Business in the same manner as such services were being provided by the Selling Entities to the Business immediately prior to the Agreement Date ("Miscellaneous Services").

Miscellaneous Services shall not include two- way radio communications, legal and credit services. 2.4 CHARGES FOR MISCELLANEOUS SERVICES. Purchaser shall pay to the Selling Entities for the supply of any or all of the Miscellaneous Services a monthly charge in the amount of Selling Entities' cost consistent with Selling Entities' current accounting practices.

The Selling Entities shall not be obligated to incur any additional costs for interim third party software licenses or sublicenses needed to continue providing the Miscellaneous Services to the Business, and all such additional costs shall be for Purchaser's account. If Purchaser requests in writing the Selling Entities to make any systems software modifications or special accommodations in connection with the Selling Entities' Miscellaneous Services and the Selling Entities agree to provide same, such will be for Purchaser's account and chargeable at a rate equal to Selling Entities' cost consistent with Selling Entities current accounting practices. 2.6 ACCOUNTING DATA. Purchaser understands and acknowledges that the accounting data for the Business has been maintained as an integral part of the accounting data for the entire Selling Entities and, therefore, the records produced as a result of the normal services covered by this Section 2 may not include all records which a stand alone business may require nor be in the form that would normally be produced for a stand alone business.

SECTION 10 LEASED EMPLOYEES 10.1 LEASED EMPLOYEES. Selling Entities will continue to employ any of the employees of the Business after the Closing at the request of Purchaser for a period ending not later than [______________, 19__] for non-exempt employees and [_________________, 19__] for exempt employees, and will lease those employees ("Leased Employees") to Purchaser during such period to enable Purchaser to operate the Business after the Closing while arrangements are made by Purchaser to employ the Leased Employees to operate the Business. Selling Entities will charge Purchaser as a fee for leasing the employees an amount equal to the total compensation of the Leased Employees during such period plus all payroll related costs for group insurance, retirement plan costs, payroll taxes, workers' compensation benefit costs and any other costs incurred by the Selling Entities as a consequence of having the Leased Employees on the Selling Entities' payroll 10 during such period. In addition, Purchaser agrees to indemnify the Selling Entities for any costs incurred by the Selling Entities under their medical plan, disability income plan and workers' compensation self insurance plan (whether incurred during or after the period for which the Leased Employees are provided to Purchaser) as a result of events occurring during the period for which the Leased Employees are leased in excess of the employee and employer contributions to such plans for the period during which the Leased Employees are provided and, if applicable, subsequent periods with respect to such Leased Employees. The intent of this provision is that neither Selling Entities nor the Selling Entities' benefit plans shall incur any costs, net of fees and indemnity amounts paid by Purchaser or the Leased Employees, related to such employees which would not be incurred if such Leased Employees had not been employees of the Selling Entities during the period for which such Leased Employees are provided to Purchaser.

In the event that such dispute is not resolved between the Parties (after such review by their accountants), such dispute shall be submitted to and finally settled under the Rules of the American Arbitration Association ("AAA") by an arbitrator 11 appointed in accordance with those Rules. The place of the arbitration shall be Houston, Texas. The determination by the arbitrator shall be final and binding upon the Parties and shall be enforceable in any court of competent jurisdiction.
