The July 31 Balance Sheet shall include all information necessary to compute the Working Capital of the Company.

Within 60 days following delivery of the July 31 Balance Sheet, the Seller shall notify the Buyer whether it agrees with the July 31 Balance Sheet. In the event that the Seller disagrees with the July 31 Balance Sheet, the Seller shall provide the Buyer with a written notice specifying the basis for the Seller's disagreement, and the Seller and the Buyer shall work in good faith to reach agreement on the composition of the July 31 Balance Sheet, but, in the event that they shall not agree within 30 days following the date of such written notice, the matter will be referred to a "Big Six" independent public accounting firm mutually agreed to by the Buyer and the Seller. The fees and disbursements of such accounting firm shall be borne equally by the Buyer and the Seller. Such accounting firm shall examine the records of the Company, and, within 30 days following the date upon which such matter shall be referred to such accounting firm, such accounting firm shall determine the disposition of any dispute with respect to the July 31 Balance Sheet (the date on which the determination is made, whether by the accounting firm or by agreement of the parties, is referred to as the "Final Determination Date"). Any such determination shall be final and binding on the parties, and may be enforced by appropriate judicial or other proceedings. (b) In the event that the Working Capital of the Company is less than the Estimated Working Capital, then the amount of such difference shall be paid by the Seller to the Buyer within two business days of the Final Determination Date, plus interest of 8% per annum payable from July 31, 1997 to the Final Determination Date. In the event that the Working Capital of the Company is more than the Estimated Working Capital, then the amount of such difference shall be paid by the Buyer to the Seller within two business days of the Final Determination Date, plus interest of 8% per annum payable from July 31, 1997 to the Final Determination Date. (c) The July 31 Balance Sheet shall be prepared in accordance with generally accepted accounting principles applied in a manner consistent with the Company's historical accounting policies and practices; except that all intercompany balances will be eliminated. (d) On or prior to 90 days from the Closing Date, the Seller will prepare and deliver to the Buyer a calculation of the State Tax Detriment (as defined below) resulting from the sale of the Company, showing all necessary information for such calculation. The Seller shall make available to the Buyer all information which may be in the possession of the Seller which the Buyer reasonable requests in order to verify the accuracy of the State Tax Detriment calculation. Within 30 days following delivery of the calculation of the State Tax Detriment, the Buyer shall notify the Seller whether it disagrees with such calculation and the Buyer shall be deemed to agree with such calculation if no notice of disagreement is received within such time period. In the event that the Buyer disagrees with such calculation, the Buyer shall attach to its notice of disagreement or incorporate therein a written notice specifying the basis for the Buyer's disagreement, and the Seller and the Buyer shall work in good faith to reach agreement on the calculation but, in the event that they shall not agree within 30 days following the date of such written notice, the matter will be referred to a nationally recognized independent public accounting firm mutually agreed to by the Buyer and the Seller. The fees and the disbursements of such accounting firm shall be borne equally by the Buyer and the Seller. Such accounting firm shall examine the records of the Seller and the Company, and, within 30 days following the date upon which such matter shall be referred to such accounting firm, such accounting firm shall determine the disposition of any dispute with respect to the calculation. Any such determination shall be final and binding on the parties, and may be enforced by appropriate judicial or other proceedings. Payment of the amount of the State Tax Detriment shall be made by the Buyer to the Seller no later than five business days after the date agreement is reached between the Buyer and the Seller or the decision of the accounting firm is made. The "State Tax Detriment" equals the difference between (A) the state Taxes payable by the Seller or any related party as a result of making the Section 338(h)(10) election contemplated by Section 5.11(c) of this Agreement and (B) the state Taxes that would have been payable as a result of the sale pursuant to this Agreement had such a Section 338(h)(10) election not been made, such calculation to be grossed up for any additional state or other Taxes payable as a result of the payment to the Seller under this provision. 2.4 The Closing.

The Buyer shall execute or cause to be executed powers of attorney or other documents necessary to enable the Seller to take all actions desired by the Seller with respect to such Proceeding to the extent such Proceeding may affect amount of Taxes for which the Seller is liable pursuant to this Agreement. The Seller shall have the right to control any such Proceedings, and, if there is substantial authority thereof, to initiate any claim for refund, file any amended return or take any other action which it deems appropriate with respect to such Taxes. Any Proceeding with respect to Taxes for a period which includes but does not end on the Closing Date shall be controlled jointly by the Seller and the Buyer. Notwithstanding the foregoing, the Seller shall not agree to any settlement concerning Taxes for any taxable period ending on or before the Closing Date which may result in a material increase in Taxes for any taxable period ending after the Closing Date without the prior written consent of the Buyer. (c) The Seller, the Company and their Affiliates, as of the Closing Date, shall terminate all Tax allocation agreements or other Tax sharing arrangements with respect to the Company, shall cause such agreements or arrangements to be of no further force and effect as regards the Company on and after the Closing Date and there shall be no further liability of the Company thereunder from and after the Closing Date.

The election will include the execution and subsequent filing of Internal Revenue Service Form 8023-A pursuant to the requirements as stated therein. The Buyer shall, within 60 days of the Closing Date, provide to the Seller an allocation of the deemed purchase price among the assets of the Company in accordance with Code Sections 338 and 1060 and any comparable provisions of state, local or foreign law, as appropriate. Such allocation shall be deemed acceptable to the Seller unless it notifies the Buyer of any objections within 30 days of receipt of such allocation. If the Seller and the Buyer are unable to agree on such allocation within 120 days of the Closing Date, then an independent accounting firm mutually acceptable to the parties hereto shall make a binding determination with respect to such allocation, the fees and expenses of which shall the paid equally by the Seller and the Buyer. (e) The Buyer, Key Energy and the Seller shall preserve all information, returns, books, records and documents relating to any liabilities for Taxes of the Company with respect to a taxable period until the later of expiration of all applicable statutes of limitation and extensions thereof or a final determination with respect to Taxes of the Company for such period. 5.12 Inspections.

(a) Agreement to Register Resales. Key Energy agrees that no later than 90 days following the Closing Date, it will file with the Commission on Form S-3, or if Form S-3 is not available to Key Energy, on Form S-1, a shelf registration statement pursuant to Rule 415 of the Securities Act (the "Shelf Registration Statement") covering the offer and resale by the Seller of (i) the shares of Key Energy Common Stock delivered to the Seller pursuant to Section 2.2(a)(ii), and (ii) the Warrant Shares (collectively, the "Registered Securities"), and will use its best efforts to cause the Shelf Registration Statement to be declared effective promptly by the Commission, and in any event within 90 days after the initial filing thereof. (b) Effectiveness of Shelf Registration Statement. Key Energy agrees to maintain the Shelf Registration Statement in effect for the maximum period allowable under the regulations promulgated by the Commission; provided that if such maximum period is less than two years from the Closing Date and if as of the end of such maximum period not all of the Registered Securities registered under the Shelf Registration Statement have been sold or are capable of being sold under Rule 144 of the Securities Act without application of the volume, manner of sale or notice restrictions, then within 10 days after the end of such maximum period Key Energy shall file either a post-effective amendment to the existing Shelf Registration Statement or a new Shelf Registration Statement covering the offer and resale by the Seller of all Registered Securities not previously sold, and Key Energy will use its best efforts to cause the same to be declared effective promptly by the Commission, and in any event within 90 days after the initial filing thereof. (c) Blue Sky Qualification.

(d) Registration Expenses. All expenses (except for any legal fees for the Seller's counsel) relating to the registration of the Registered Securities pursuant to this Agreement (including, but not limited to, the expenses of any qualifications under the blue-sky or other state securities laws and compliance with governmental requirements of preparing and filing any post-effective amendments or prospectus supplements required for the lawful distribution of the Registered Securities to the public in connection with such registration) will be paid by Key Energy.

The registration rights provided by this Section 5.14 are transferable to any Affiliate of the Seller to which the Registered Securities may be transferred and to any single purchaser of all (but not less than all) of the Registrable Securities, provided, in each case, that the Affiliate or the purchaser agrees (in a writing that names the Company as an explicit third party beneficiary) to be bound by all the terms and provisions of this Section 5.14. (g) Undertaking to File Reports and Cooperate in Rule 144 and Rule 145 Transactions. For as long as the Seller is subject to Rule 144 of the Securities Act with respect to the Registered Securities, Key Energy will use its best efforts to timely file all annual, quarterly and other reports required to be filed by it under Section 13 or 15(d) of the Exchange Act and the rules and regulations of the Commission thereunder, as amended from time to time. If the Seller proposes to sell any Registered Securities pursuant to Rule 144, Key Energy shall cooperate with the Seller so as to enable such sales to be made in accordance with applicable laws, rules and regulations, the requirements of Key Energy's transfer agent, and the reasonable requirements of the broker through which the sales are proposed to be executed. Without limiting the generality of the foregoing, Key Energy shall, upon request, furnish with respect to each such sale (i) a written statement certifying that Key Energy has complied with the public information requirements of Rule 144 and (ii) an opinion of Key Energy's counsel regarding such matters as Key Energy's transfer agent or such stockholder's broker may reasonably desire to confirm.

(ii) Notice to the Seller.

(iii) Incorporation of Information. If requested by the Seller, promptly incorporate in a prospectus supplement or post-effective amendment such information as the Seller reasonably requests to be included therein, including, without limitation, with respect to the Registered Securities being sold by the Seller, and promptly make all required filings of such prospectus supplement or post-effective amendment.

For purposes of this Section 5.14(h), the "Seller" shall include any Affiliate of the Seller or other Person to which the Registered Securities and registration rights with respect thereto are transferred. Also for purposes of this Section 5.14(h), Registered Securities shall refer to any capital stock of Key Energy or its successors into which Key Energy shares may be exchanged or converted. (i) Indemnification. (i) Key Energy will, and hereby does, indemnify and hold harmless, to the extent permitted by applicable law, the Seller, its officers and directors, if any, and each Person, if any, who controls the Seller within the meaning of Section 15 of the Securities Act, and their respective successors, against all losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses, including legal fees incurred in investigating or defending any such loss, claim, damage or liability (under the Securities Act or common law or otherwise) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Shelf Registration Statement or prospectus (and as amended or supplemented if Key Energy shall have furnished any amendments or supplements thereto), covering the Registrable Securities or any preliminary prospectus or other document incident thereto or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities (or proceedings in respect thereof) or expenses arise out of or are based upon any untrue statement or alleged untrue statement contained in or by any omission or alleged omission from information furnished in writing to Key Energy by the Seller expressly for use therein. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Seller, its officers, directors or any Person, if any, who controls the Seller as aforesaid, and shall survive the transfer of such securities by the Seller. (ii) The Seller will and hereby does indemnify and hold harmless, to the extent permitted by applicable law, Key Energy, its officers and directors and each Person, if any, who controls Key Energy within the meaning of Section 15 of the Securities Act, and their respective successors, against all losses, claims, damages, liabilities (or proceedings in respect thereof) and expenses, including legal fees incurred in investigating or defending any such loss, claim, damage or liability (under the Securities Act or common law or otherwise) arising out of or based upon any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be state in any Shelf Registration Statement or prospectus or preliminary prospectus or any amendment thereof or supplement thereto or other document incident thereto or arising out of or based upon any omission or alleged omission to state therein a material fact, or necessary to make the statements therein by the Seller not misleading, but only to the extent that such untrue statement is contained in, or such omission is in, information furnished in a writing by the Seller expressly for use therein, provided that the Seller's obligations hereunder shall be limited to an amount equal to the proceeds to the Seller of the Registrable Securities sold pursuant to such registration statement. (iii) Any Person entitled to indemnification under the provisions of this Section 5.14(i) shall (A) give prompt notice to the indemnifying Person of any claim with respect to which it seeks indemnification and (B) unless in such indemnified Person's reasonably judgment a conflict of interest between such indemnified and indemnifying Persons may exist in respect to such claim, permit such indemnifying Person to assume the defense of such claim, with counsel reasonably satisfactory to the indemnified Person; and, if such defense is so assumed, such indemnifying Person shall not enter into any settlement without the consent of the indemnified Person if such settlement attributes liability to the indemnified Person and such indemnified Person shall not be subject to any liability for any settlement made without such consent (which shall not be unreasonably withheld). In the event that an indemnifying Person shall not be entitled, or elects not, to assume the defense of a claim, such indemnifying Person shall not be obligated to pay the fees and expenses of more than one counsel or firm of counsel for all parties indemnified by such indemnifying Person in respect of such claim, unless, in the reasonable judgment of any such indemnified Person, a conflict of interest may exist between such indemnified Person and any other of such indemnified Persons in respect of such claim. (iv) If for any reason the foregoing indemnity is unavailable, then, subject to the proviso in Section 5.14(i)(ii) in the case of the Seller, the indemnifying Person shall contribute to the amount paid or payable by the indemnified Person as a result of such losses, claims, damages, liabilities or expenses (A) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying Person on the one hand and the indemnified Person on the other or (B) if the allocation provided by clause (A) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits received by the indemnifying Person on the one hand and the indemnified Person on the other but also the relative fault or the indemnifying Person and the indemnified Person as well as any other relevant equitable considerations. The relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying Person or by the indemnified Person and by the Persons' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a Person as a result of the losses, claims, damages, liabilities and expenses shall be deemed to include any legal or other fees or expenses reasonably incurred by the Person in connection with investigating or defending any action or claim. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. (v) An indemnifying Person shall make payments of all amounts required to be made pursuant to the foregoing provisions of this Section 5.14(i) to or for the account of the indemnified Person from time to time promptly upon receipt of bills or invoices relating thereto or when otherwise due or payable. (j) Suspension of Resales. Key Energy shall be entitled to require that the Seller refrain from effecting any public sales or distributions of the Registered Securities, pursuant to the Shelf Registration Statement that has been declared effective by the Commission, if the board of directors of Key Energy in good faith determines that such public sales or distributions would interfere in any material respect with any transaction involving Key Energy that is material to Key Energy. The board of directors shall, as promptly as practicable, give the Seller written notice of any such development, which notice also shall contain a general statement of the reasons for such restriction on use and an estimate of the anticipated length of the period of the restriction. In the event of a request by the board of directors that the Seller refrain from effecting any public sales or distributions of the Registered Securities, Key Energy shall be required to lift such restrictions regarding effecting public sales or distributions of the Registered Securities as soon as reasonably practicable after the board of directors shall determine that public sales or distributions by the Seller of the Registered Securities shall not interfere with such transaction; provided, that in any event no requirement that the Seller refrain from effecting public sales or distributions in the Registered Securities shall extend for more than 15 days at any one time or more than 30 days over the entire period the Shelf Registration Statement is required to be in effect. 5.15 Books and Records. Until April 30, 2001 (or for such longer period as may be required by law), no party or any of its Affiliates shall destroy or give up possession of an original or any copy of the books and records relative to any matter for which a party or its Affiliates shall have any continuing responsibility under this Agreement or the Oxy Purchase Agreement without first offering the other parties the opportunity, at their expense, to obtain such original or copy thereof.

(d) So long as the Indemnifying Party has assumed and is conducting the defense of the Third Party Claim in accordance with Section 8.4(b), (i) the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably) unless the judgment or proposed settlement involves only the payment of money damages by one or more of the Indemnifying Parties and does not impose an injunction or other equitable relief upon the Indemnified Party and (ii) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably). 8.5 Matters Involving the Parties. In the event an Indemnified Party should have a claim against an Indemnifying Party hereunder that does not involve a Third Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a written notice describing in reasonable detail the nature of the claim, an estimate of the amount of damages attributable to such claim and the basis of the Indemnified Party's request for indemnification under this Agreement. If the Indemnifying Party does not notify the Indemnified Party within 30 days of its receipt of such notice that the Indemnifying Party disputes such claim, the claim shall be deemed a Liability of the Indemnifying Party hereunder and shall be paid within 30 days of the expiration of the initial 30-day period. If the Indemnifying Party has timely disputed such claim as provided above, such dispute shall be resolved by litigation as provided herein. 8.6 Limitations on Indemnification. (a) No party shall be entitled to indemnification hereunder unless and until the aggregate of all amounts for which indemnity would otherwise be due to such party exceeds $100,000, in which case such other parties shall be responsible for all amounts of such liability excluding such threshold amount; provided that (i) the Seller shall be indemnified for the full amount of any Adverse Consequences pursuant to Section 8.3(b) and (ii) each party shall be indemnified for the full amount of any Taxes for which the other party is liable pursuant to Section 5.11, in each case without regard to any such threshold amount. (b) Notwithstanding anything to the contrary, no party shall be liable for Adverse Consequences pursuant to this Article 8 in excess of the Purchase Price (with stock and warrants valued at the Closing Date) except for liabilities for Adverse Consequences pursuant to Section 8.3(b) and Taxes pursuant to Section 5.11. 8.7 Environmental Claims. Notwithstanding anything in this Agreement to the contrary, and notwithstanding the fact that any representation, warranty or covenant in this Agreement might be interpreted to cover the same, this Section 8.7 shall be the sole and exclusive provision of this Agreement, and represents the Buyer's and Key Energy's sole and exclusive remedy against the Seller or any of its current Affiliates with respect to Environmental Claims. To the extent the Seller or any of its current Affiliates is (i) an indemnified party for Environmental Claims under the Oxy Purchase Agreement and (ii) actually receives payment from Oxy after following the reasonable instructions of the Buyer to prosecute such Environmental Claims, at the sole expense of the Buyer, in accordance with the provisions of the Oxy Purchase Agreement, the Seller shall remit any amounts recovered, less unrecovered costs to prosecute any Environmental Claim, to the Buyer in full payment for such Environmental Claim. In the event (1) the Seller or any of its current Affiliates (A) is not an indemnified party for Environmental Claims under the Oxy Purchase Agreement or (B) is unable to recover any amount thereunder or (2) any Environmental Claim arises with respect to the period between April 30, 1996 and the Closing Date, the Buyer and Key Energy will have no recourse against the Seller or its Affiliates, and shall indemnify, defend and hold the Seller and its Affiliates harmless therefor. ARTICLE 9. MISCELLANEOUS. 9.1 Press Releases and Public Announcements. Neither the Buyer nor Key Energy shall issue any press release or make any public announcement relating to the subject matter of this Agreement without the prior written approval of the Seller; provided, however, that the foregoing shall not apply to any announcement or written statement which, upon written advice of counsel provided to the Seller, is required by law to be made. 9.2 No Third-Party Beneficiaries. This Agreement shall not confer any rights or remedies upon any person other than the parties and their respective successors and permitted assigns. 9.3 Entire Agreement.
