ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS

         On October 1, 1997, Key Four Corners, Inc., a wholly owned subsidiary
of Key Energy Group, Inc. (the "Company"), completed an acquisition of
substantially all of the assets of Big A Well Service Co., Sunco Trucking Co.
and Justis Supply Co., Inc., each of which is a closely held New Mexico
corporation (collectively, the "Sellers"). The assets acquired from the Sellers
(the "Assets") consist of equipment and vehicles utilized in working over and
servicing oil and gas wells, oil field fluid sales and services, oil and gas
well drilling operations and the operation of a fabrication, repair and machine
shop in the Four Corners area of the Southwest as well as certain real property
and improvements located in Farmington, New Mexico. The consideration paid for
the Assets was $28 million, subject to certain adjustments based on the Sellers'
net working capital as of October 1, 1997, and 125,000 shares of common stock,
par value $.10 per share, of the Company. The amount of such consideration, the
cash portion of which was financed by the Company's credit facility and
available cash balances, was determined by negotiations between the Company, the
Sellers and the principal stockholder of Coleman Oil & Gas Co., the sole
stockholder of all of the issued and outstanding capital stock of each of the
Sellers. No material relationship exists between the Sellers or the principal
stockholder of Coleman Oil & Gas Co. and the Company or any of its affiliates,
any director or officer of the Company or any associate of any such officer or
director. The Company intends for the assets of the Sellers to be used by Key
Four Corners, Inc. in its well servicing operations.

                  (h) all other or additional privileges, rights, interests,
         properties and assets of the Sellers of every kind and description and
         wherever located that are used in the Businesses or intended for use in
         the Businesses in connection with, or that are necessary for the
         continued conduct of, the Businesses.

         The purchased assets shall not include the following (collectively, the
"EXCLUDED ASSETS"): (i) all assets in possession of the Sellers but owned by
third parties; (ii) the assets listed


                                        2

on Schedule 1.1(a)-2; (iii) the corporate charter, related organizational
documents and minute books of the Sellers; and (iv) the consideration paid or 
payable by Buyer to Sellers pursuant to Section 1.2 hereof.  The assets 
purchased and sold pursuant to this Agreement are collectively referred to 
herein as the "ASSETS."

         1.2. Consideration for Assets. As consideration for the sale of the
Assets and for the other covenants and agreements of COG, Sellers and Coleman
contained herein and subject to adjustments pursuant to Section 1.3, Buyer
agrees to pay to Sellers on the Closing Date, an aggregate purchase price (the
"PURCHASE PRICE") of (i) $26,993,000 ($28,000,000 less cash paid for Real
Estate) in immediately available funds to accounts designated by the Sellers
(the "CASH CONSIDERATION") and (ii) 125,000 shares of the common stock, par
value $.10 per share, of Key (the "KEY SHARES"), subject to appropriate
adjustment for any share split or combination in the common stock of Key during
the period between the date hereof and the Closing Date.

         The aggregate Purchase Price payable hereunder shall be paid among the
Sellers in accordance with Schedule 1.2, provided that the Cash Consideration
portion of the Purchase Price shall be adjusted pursuant to Section 1.3.

         1.3. Post-Closing Adjustment with Respect to Sellers' Net Value. Within
45 days after the Closing Date, Buyer shall provide to Sellers a schedule
setting forth the Sellers' Net Value (as hereinafter defined) as of the Closing
Date. If Sellers' Net Value is greater than $6,901,449, then Buyer shall
reimburse Sellers in cash the amount which equals the Sellers' Net Value at the
Closing Date less $6,901,449. If the Sellers' Net Value at the Closing Date is
less than $6,901,449, then Sellers, COG and Coleman jointly and severally agree
to pay to Buyer an aggregate amount in cash equal to $6,901,449 minus the
Sellers' Net Value at the Closing Date. Sellers shall have 30 days after receipt
of the schedule setting forth the Sellers' Net Value calculation to object to
the same; if no such objection is made, such net value calculation by Buyer
shall be deemed accepted by each of the Sellers, and the required payment shall
be made within ten days thereafter. If any of the Sellers object to the Sellers'
Net Value calculation, then the parties agree to mutually cooperate in reaching
agreement with respect thereto. If no such agreement can be reached within 90
days after the Closing Date, then the parties agree that either party may submit
the dispute to an independent accounting firm mutually acceptable to Buyer and
the Sellers, whose determination shall be made not later than 120 days after the
Closing Date and whose determination shall be binding on all the parties hereto.
All charges of such accounting firm and other expenses directly incurred in
making such determination shall be borne 50% by the Buyer and 50% by the
Sellers.

         For purposes hereof, the Sellers' Net Value shall mean with respect to
a given date (i) the sum of (1) the amount by which (A) the total current assets
plus the other assets (less amounts due from affiliates or officers) exceeds (B)
the total current liabilities plus the total long-term liabilities (less accrued
or deferred income taxes and amounts due affiliates or officers), plus (2) total
funds expended for the purchase of capital equipment during the period between

March 31, 1997 and the Closing Date in accordance with Section 3.1.7. Schedule
3.1 hereto shows the computation of Sellers' Net Value as of March 31, 1997,
based on the information contained in the Sellers' Financial Statements.


         Any amount payable to Sellers under this Section 1.3 shall be paid
among the Sellers in accordance with the ratio which (i) the portion of the Cash
Consideration allocated to each Seller under Section 1.2 bears to (ii) the total
amount of the Cash Consideration.

         1.4. Assumption of Liabilities. On the Closing Date, Buyer shall assume
those, and only those, liabilities and obligations of the Sellers hereinafter
listed and defined as the "ASSUMED LIABILITIES." For purposes of this Agreement,
"Assumed Liabilities" means (i) all items comprising each account balance under
the captions "Current Liabilities" or "Long Term Liabilities" on the March 31,
1997 unaudited balance sheet and (ii) liabilities incurred by the Sellers in the
ordinary course of business subsequent to the Balance Sheet Date for the account
or benefit of Buyer or, of the property, other assets and businesses of the
Sellers to be transferred to Buyer pursuant to this Agreement; provided,
however, the Assumed Liabilities shall not include any Excluded Liabilities. As
used herein, the term "EXCLUDED LIABILITIES" means (a) all liabilities of any of
the Sellers which are not "Assumed Liabilities," (b) any and all federal and
state income tax liability of any of the Sellers, COG or Coleman (c) any and all
intercompany accounts and (d) all attorneys' and accountants' fees and expenses
and any other fees and expenses incurred by the Sellers, COG or Coleman in
connection with transactions contemplated hereby.

         1.5. Time and Place of Closing. The closing of the transactions
contemplated by this Agreement (the "CLOSING") shall be at the offices of
Laflin, Lieuwen, Tucker, Pick & Heer, P.A. located at 6400 Uptown Boulevard,
Northeast, Suite 600 West, Albuquerque, New Mexico 87110, on the second business
day following the satisfaction by all parties hereto of all of the conditions to
the Closing or as soon as practicable thereafter (the "CLOSING DATE").

                         REPRESENTATIONS AND WARRANTIES

         2.1. Representations and Warranties of the Sellers, COG and Coleman.

reference of this Agreement to which such disclosure relates), each of the
Sellers, COG and Coleman, jointly and severally, represent and warrant to Buyer
as follows:

                  2.1.1. Organization and Good Standing. Each of COG and the

         corporations authorized to do business in all jurisdictions in which
         the character of the properties owned or the nature of the businesses
         conducted by them would make such qualification or licensing necessary.

                  2.1.2.   Agreements Authorized and their Effect on Other 
         Obligations. The execution and delivery of this Agreement have been 
         authorized by all necessary corporate, shareholder and other action 
         on the part of each of COG and the Sellers, and this Agreement is the 

         valid and binding obligation of each of COG, the Sellers and Coleman
         enforceable against each of such parties in accordance with its terms,
         except as enforceability may be limited by bankruptcy, insolvency,
         reorganization, debtor relief or similar laws affecting rights of
         creditors generally and subject to normal equitable principles. The
         execution, delivery and performance of this Agreement and the
         consummation of the transactions contemplated hereby, will not conflict
         with or result in a violation or breach of any term or provision of,
         nor constitute a default under (i) the charter or bylaws (or other
         organizational documents) of any of COG, the Sellers or Coleman, (ii)
         any obligation, indenture, mortgage, deed of trust, lease, contract or
         other agreement to which any of COG, the Sellers or Coleman is a party
         or by which any of COG, the Sellers or Coleman or their respective
         properties are bound; or (iii) any provision of any law, rule,
         regulation, order, permit, certificate, writ, judgment, injunction,
         decree, determination, award or other decision of any court,
         arbitrator, or other governmental authority to which any of COG or the
         Sellers or any of their respective properties are subject.

                  2.1.3.   Subsidiaries.  None of the Sellers has any subsidiary
         corporations or any interest in any other organization, incorporated 
         or unincorporated, partnership or any other entity of any type.

                  2.1.4. Liabilities. The Sellers do not have any liabilities or
         obligations, either accrued, absolute, contingent, or otherwise, or
         have any knowledge of any potential liabilities or obligations that
         would materially and adversely affect the value and conduct of the
         Businesses by the Buyer or the Assets, other than those (i) reflected
         or reserved against in the March 31, 1997 unaudited balance sheet of
         the Sellers or (ii) incurred in the ordinary course of business since
         March 31, 1997.

                  2.1.5. Contracts. Schedule 1.1(d) hereto sets forth a true,
         complete and accurate list of all material Contracts of the Sellers,
         including leases under which the Sellers are lessor or lessee, which
         relate to the Assets or the Businesses and are to be performed in whole
         or in part after the date hereof. All of the material Contracts are in
         full force and effect, and constitute valid and binding obligations of
         the Sellers. The Sellers are not, and no other party to any of the
         Contracts is, in default thereunder, and no event has occurred which
         (with or without notice, lapse of time, or the happening of any other
         event) would constitute a default thereunder. No material Contract has
         been entered into on terms that could reasonably be expected to have an
         adverse effect on the use of the Assets or the Businesses by Buyer.
         None of COG, the Sellers or Coleman has received any information which


                                        5

<PAGE>   11

         would cause any of such parties to conclude that any customer of the
         Sellers will (or is likely to) cease doing business with Buyer (or its
         successors) as a result of the consummation of the transactions
         contemplated hereby. All of the Contracts set forth on Schedule 1.1(d),
         other than the leases to be entered into pursuant to Section 4.2.10,
         are assignable (and as of the Closing Date will be validly assigned) to
         Buyer without the consent of any other party thereto, other than
         consents obtained no later than the Closing Date.

                  2.1.6.   Title to and Condition of Assets.  The Sellers have 
         good, indefeasible and marketable title to all of the Assets, free 
         and clear of any Encumbrances (defined below). All of the
         Assets are in a state of good operating condition and
         repair, ordinary wear and tear excepted, and are free from any known
         defects except as may be repaired by routine maintenance and such minor
         defects as to not substantially interfere with the continued use
         thereof in the conduct of normal operations. All of the Assets
         materially conform to all applicable laws governing their use. No
         notice of any violation of any law, statute, ordinance, or regulation
         relating to any of the Assets has been received by any of the Sellers,
         COG or Coleman, except such as have been fully complied with. For
         purposes of this Agreement, the term "ENCUMBRANCES" means all liens,
         security interests, pledges, mortgages, deeds of trust, claims, rights
         of first refusal, options, charges, restrictions or conditions to
         transfer or assignment, liabilities, obligations, privileges, equities,
         easements, rights of way, limitations, reservations, restrictions, and
         other encumbrances of any kind or nature.

                  2.1.7. Licenses and Permits. Schedule 1.1(e) hereto sets forth
         a true, complete and accurate list of all Permits material to the
         Businesses and the operation, maintenance and use of the Assets in the
         manner in which they are now being operated, maintained and used. Each
         of the Sellers' Permits and the Sellers' rights with respect thereto is
         valid and subsisting, in full force and effect, and enforceable by the
         respective Sellers subject to administrative powers of regulatory
         agencies having jurisdiction. Each of the Sellers is in material
         compliance in all respects with the terms of each of the Sellers'
         Permits. None of the Sellers' Permits have been, or to the knowledge of
         any of the Sellers, COG or Coleman, are threatened to be, revoked,
         canceled, suspended or modified. Upon consummation of the transactions
         contemplated hereby, all of the Sellers' Permits that are assignable
         without the consent of any governmental or other agency shall be
         assigned to the Buyer, and Buyer's rights with respect thereto will be
         valid and subsisting in full force and effect, and enforceable by Buyer
         subject only to the administrative powers of regulatory agencies having
         jurisdiction over the assigned Sellers' Permits.

                  2.1.8. Intellectual Property. Schedule 1.1(c) hereto sets
         forth a true, complete and accurate list of all Intellectual Property
         material to the continued conduct of the Businesses. The Sellers'
         Intellectual Property is owned or licensed by the Sellers free and
         clear of any Encumbrances. The Sellers have not granted to any other
         person any license to use any Sellers' Intellectual Property. Neither
         the Sellers, COG nor Coleman has received any notice of infringement,
         misappropriation, or conflict with the intellectual property rights of
         others in connection with the use by the Sellers of the Sellers'
         Intellectual Property.

                  2.1.9. Financial Statements. The Sellers have delivered to
         Buyer copies of certain unaudited financial statements of the Sellers,
         copies of which are attached hereto as Schedule 2.1.9 (collectively,
         the "SELLERS' FINANCIAL STATEMENTS") as of and for the five months
         ended March 31, 1997 (the "BALANCE SHEET DATE"). The Sellers' Financial
         Statements are true, correct and complete in all material respects and
         present fairly and fully the financial condition of the Sellers as of
         the dates and for the periods indicated thereon, and have been prepared
         in accordance with generally accepted accounting principles as
         promulgated by the American Institute of Certified Public Accountants
         ("GAAP") applied on a consistent basis, except as noted therein. Each
         of the Sellers' Financial Statements include all adjustments


         which are necessary for a fair presentation of the applicable Seller's
         results for that period. The inventories of the Sellers reflected in
         the Sellers' Financial Statements, or which have thereafter been
         acquired by the Sellers, consist of items of a quality and quantity
         salable in the normal course of the applicable business. The values at
         which such inventories are carried are in accordance with GAAP applied
         on a consistent basis, and are consistent with the normal inventory
         level and practices of the Sellers with respect to the Businesses.

                  2.1.10.  Additional Information.  Attached as Schedule

                  2.1.12. Assets; Necessary Consents. The Assets constitute all
         of the assets necessary to conduct the Business as historically
         conducted by each of the Sellers (other than the Excluded Assets). As
         of the Closing Date, each of the Sellers will have obtained and

         including, without limitation, any consents required to assign the
         Contracts and the Sellers' Permits.

                  2.1.13. Environmental Matters. None of the current or past

         has received any notice (whether formal or informal, written or oral)
         from any entity, governmental agency or individual regarding any
         existing, pending or threatened investigation or inquiry related to
         violations of any Environmental Law or regarding any claims for
         remedial obligations or contribution for removal costs or damages under
         any Environmental Law. There are no writs, injunction decrees, orders
         or judgments outstanding, or lawsuits, claims, proceedings or
         investigations pending or, to the knowledge of any of the Sellers, COG
         or Coleman, threatened, relating to the ownership, use, maintenance or
         operation of the Assets or the conduct of the Business, nor, to the
         knowledge of any of the Sellers, COG or Coleman, is there any basis for
         any of the foregoing. Buyer will not be required to obtain any permits,
         licenses or similar authorizations pursuant to any Environmental Law
         after the Closing Date to operate and use any of the Assets for their
         current or proposed purposes and uses, except for permits, licenses or
         similar authorizations that would not have a Material Adverse Effect on
         the Sellers. The Assets include all environmental and pollution control
         equipment necessary for material compliance with
         applicable Environmental Law. Except as disclosed on Schedule 2.1.13
         (i) no Hazardous Materials (defined below) have been or are currently
         being used by any of the Sellers in the operation of the Assets, (ii)
         no Hazardous Materials are or have ever been situated on or under any
         of the Sellers' properties, whether owned or leased, or incorporated
         into any of the Assets, (iii) there are no, and there have never been
         any, underground storage tanks (as defined under Environmental Law)
         located under any of the Sellers' properties, whether owned or leased,
         and (iv) there are no environmental conditions or circumstances,
         including the presence or release of any Hazardous Materials, on any
         property presently or previously owned or leased by any of the Sellers,
         or on any property on which Hazardous Materials generated by any of the
         Sellers' operations or the use of the Assets were disposed of. The term
         "ENVIRONMENTAL LAW" means any and all laws, rules, orders, regulations,
         statutes, ordinances, codes, decrees, and other legally enforceable
         requirements (including, without limitation, common law) of the United
         States, or any state, regional, city, local, municipal or other
         governmental authority or quasi-governmental authority, regulating,
         relating to, or imposing environmental standards of conduct concerning
         protection of the environment or human health, or employee health and
         safety as from time to time has been or is now in effect. The term
         "HAZARDOUS MATERIALS" means (x) asbestos, polychlorinated biphenyls,
         urea formaldehyde, lead based paint, radon gas, petroleum, oil, solid
         waste, pollutants and contaminants, and (y) any chemicals, materials,
         wastes or substances that are defined, regulated, determined or
         identified as toxic or hazardous in any Environmental Law.

                  2.1.14. Employee Benefit Plans; Labor Issues. Upon request ,
         each of the Sellers will deliver to the Buyer copies of the Employee
         Plans and any other health, dental and life insurance plans, bonus,

                                       10
<PAGE>   16

         deferred compensation, pension, profit sharing and retirement plans and
         all other employee benefit plans, programs or arrangements providing
         benefits for employees of any of the Sellers (the "BENEFIT PLANS").
         Each of the Benefit Plans has been administered and maintained in
         material compliance with the requirements of the Employee Retirement
         Income Security Act of 1974, as amended ("ERISA"), and, if applicable,
         the Internal Revenue Code of 1986, as amended (the "CODE"), and all
         other applicable laws. There is no "ACCUMULATED FUNDING DEFICIENCY" (as
         such term is defined in Section 302 of ERISA or Section 412 of the
         Code) with respect to a Benefit Plan that is an "EMPLOYEE PENSION
         BENEFIT PLAN" (as defined in Section 3(2) of ERISA), and there has been
         no application for waiver of the minimum funding standards imposed by
         Code Section 412 with respect to any such plan. There are no pending
         or, to the knowledge of any of the Sellers, COG or Coleman, threatened
         claims by or on behalf of the Benefit Plans, the United States
         Department of Labor, the Internal Revenue Service, or by any current or
         former employee of any of the Sellers or beneficiary of such current or
         former employee alleging a breach of any fiduciary duties or a
         violation of applicable state or federal law which could result in a
         material liability on the part of any of the Sellers or a Benefit Plan
         under ERISA or any other law (other than benefit claims and funding
         obligations in the ordinary course of business). None of the Sellers
         has suffered or otherwise caused a "complete withdrawal" or "partial
         withdrawal," as such terms are respectively defined in Sections 4203
         and 4205 of ERISA, from any Multiemployer Pension Plan, as such term is
         defined in Section 3(37) of ERISA.

                  None of the Sellers have engaged in any unfair labor practices
         which could reasonably be expected to result in an adverse effect on
         the Business or the Assets. None of the Sellers have any dispute with
         any of their existing or former employees, and there are no labor
         disputes or, to the knowledge of any of the Sellers, COG or Coleman,
         any disputes threatened by current or former employees of any of the
         Sellers.

                  2.1.15. Investigations; Litigation. Except as required
         pursuant to the Hart-Scott- Rodino Antitrust Improvements Act of 1978
         and the rules and regulations promulgated thereunder (collectively,
         "HSR"), no investigation or review by any governmental entity with
         respect to any of the Sellers or any of the transactions contemplated
         by this Agreement is pending or, to the knowledge of any of the
         Sellers, COG or Coleman, threatened, nor has any governmental entity
         indicated to any of the Sellers, COG or Coleman an intention to conduct
         the same. Except as disclosed on Schedule 2.1.15, there is no suit,
         action, or legal, administrative, arbitration, or other proceeding or
         governmental investigation pending to which any of the Sellers, COG or
         Coleman is a party or, to the knowledge of any of the Sellers, COG or
         Coleman, might become a party.

                  2.1.16. Absence of Certain Businesses Practices. None of the
         Sellers, COG or Coleman, nor any officer, employee or agent of any of
         the Sellers or COG, nor any other person acting on behalf of any of the
         Sellers, COG or Coleman, has, directly or indirectly, within the past
         five years, given or agreed to give any gift or similar benefit to any
         customer, supplier, government employee or other person who is or may

                                       11
<PAGE>   17

         be in a position to help or hinder the profitable conduct of the
         Businesses or the profitable use of the Assets (or to assist any of the
         Sellers in connection with any actual or proposed transaction) which if
         not given in the past, may more likely than not have had an adverse
         effect on the profitable conduct of the Business or the profitable use
         of the Assets, or if not continued in the future, may more likely than
         not adversely affect the profitable conduct of the Businesses or the
         profitable use of the Assets.

                  2.1.17. Solvency. None of the Sellers are presently insolvent,
         nor will any of the Sellers be rendered insolvent by the occurrence of
         the transactions contemplated by this Agreement. The term "INSOLVENT",
         with respect to a particular Seller, means that the sum of the present
         fair and saleable value of such Seller's assets does not and will not
         exceed its debts and other probable liabilities, and the term "DEBTS"
         includes any legal liability whether matured or unmatured, liquidated
         or unliquidated, absolute fixed or contingent, disputed or undisputed
         or secured or unsecured.

                  2.1.18. Untrue Statements. This Agreement and all other
         agreements executed by any of the Sellers, COG or Coleman and delivered
         to Buyer does not 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.

                  2.1.19. Transactions with Management. Except as set forth on 
         Schedule 2.1.19, none of the Sellers is a party to any contract, lease
         or agreement with any of the officers or directors, any of the Sellers,
         COG or Coleman or any of their affiliates or family members,
         as applicable.

                  2.1.20. Compliance with Other Laws. None of the Sellers is in
         material for violation of or in material default with respect to, or in
         alleged violation of or alleged default with respect to the
         Occupational Safety and Health Act (29 U.S.C. ss. 651 et seq., as
         amended), or any applicable law or any applicable rule, regulation, or
         any writ or decree of any court or any governmental commission, board,
         bureau, agency, or instrumentality, or delinquent with respect to any
         report required to be filed with any governmental commission, board,
         bureau, agency or instrumentality.

                  2.1.21. Taxes. The federal income tax returns of the Sellers
         for the years 1995 and 1996 have been provided to the Buyer prior to
         the date hereof. Proper and accurate federal, state and local income,
         sales, use, franchise, gross revenue, turnover, excise, payroll,
         property, employment, customs duties and any and all other tax returns,
         reports, and estimates have been filed with appropriate governmental
         agencies, domestic and foreign, by each of the Sellers and COG for each
         period for which any returns, reports, or estimates were due. All taxes
         shown by such returns to be payable have been paid. All sales taxes
         have been properly collected and accounted for through the date hereof
         by each of the Sellers, and the Sellers have made all required deposits
         of such taxes with all taxing authorities. The tax provision reflected


                                       12
<PAGE>   18

         in each of the Sellers' financial statements as of March 31, 1997 is
         adequate to cover liabilities of each of the Sellers at the date
         thereof for all taxes of any character whatsoever applicable to each of
         the Sellers or its assets or business. No waiver of any statute of
         limitations executed by any of the Sellers or by COG with respect to
         federal or state income or other tax is in effect for any period. No
         deficiencies for any taxes have been proposed, asserted or assessed
         against any of the Sellers, COG, and no requests or waivers of the time
         to assess any such tax are pending. The federal income tax returns of
         the Sellers or COG have not been audited by the Internal Revenue
         Service since 1990. No audit of any federal or state or other tax
         return of any of the Sellers or COG is presently in process nor has an
         appointment for or notice of any such audit been requested or given by
         any taxing authority.

                  2.1.22. Finder's Fee. All negotiations relative to this
         Agreement and the transactions contemplated hereby have been carried on
         by the Sellers, COG and Coleman and their respective counsel directly
         with Buyer and its counsel, without the intervention of any other
         person in such manner as to give rise to any valid claim against any of
         the parties hereto for a brokerage commission, finder's fee or any
         similar payment.

         2.2. Investment Representations. Each of the Sellers acknowledges, 
represents and agrees that:

                  2.2.1. Sellers' Investment Suitability and Related Matters.
         (i) Key has made available to the Sellers and COG the information and
         documents described in Section 2.4.3, (ii) the Sellers understand the
         risks associated with ownership of Key Common Stock, and (iii) the
         Sellers are capable of bearing the financial risks associated with such
         ownership.

                  2.2.2.    Key Shares Not Registered.  The Key Shares have not
         been registered under the Securities Act of 1933, as amended (the 
         "SECURITIES ACT"), or registered or qualified under any applicable 
         state securities laws.

                  2.2.3. Reliance on Representations. The Key Shares are being
         issued to the Sellers in reliance upon exemptions from such
         registration or qualification requirements, and the availability of
         such exemptions depends in part upon the Sellers' bona fide investment
         intent with respect to the Key Shares.

                  2.2.4. Investment Intent. The Sellers' acquisition of the Key
         Shares are solely for their respective own accounts for investment, 
         and the Sellers are not acquiring the Key Shares for the account of 
         any other person or with a view toward distribution thereof.

                  2.2.5. Permitted Resale. The Sellers shall not offer for sale,
         sell, transfer, pledge, hypothecate or otherwise dispose of any of the
         Key Shares except in accordance with the registration requirements of
         the Securities Act and applicable state securities laws or upon

                                       13
<PAGE>   19

         delivery to Key of an opinion of legal counsel reasonably satisfactory
         to Key that an exemption from registration is available.

                  2.2.6. Investor Sophistication.  Each of the Sellers has such
         knowledge and experience in financial and business matters that it is 
         capable of evaluating the merits and risks of an investment in the 
         Key Shares, and to make an informed investment decision with
         respect thereto.

                  2.2.7. Availability of Information. Each of the Sellers has
         had the opportunity to ask questions of, and receive answers from Key's
         officers and directors concerning the Seller's acquisition of the Key
         Shares and to obtain such other information concerning Key and the Key
         Shares, to the extent Key's officers and directors possessed the same
         or could acquire it without unreasonable effort or expense, as the
         Sellers deemed necessary in connection with making an informed
         investment decision.

                  2.2.8.    Restrictive Legends.  In addition to any other 
         legends required by law or the other agreements entered into in 
         connection herewith, each certificate evidencing the Key Shares will
         bear a conspicuous restrictive legend substantially as follows:

                  THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER
                  THE SECURITIES ACT OF 1933, AS AMENDED ("ACT"), OR UNDER ANY
                  APPLICABLE STATE SECURITIES LAWS, AND THEY CANNOT BE OFFERED
                  FOR SALE, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE HYPOTHECATED
                  EXCEPT IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF THE
                  ACT AND SUCH OTHER STATE LAWS OR UPON DELIVERY TO THIS
                  CORPORATION OF AN OPINION OF LEGAL COUNSEL SATISFACTORY TO THE
                  CORPORATION THAT AN EXEMPTION FROM REGISTRATION IS AVAILABLE.

         2.3.     Representations and Warranties of Buyer. Buyer represents and
warrants to each of the Sellers, COG and Coleman as follows:

                  2.3.1. Organization and Good Standing. Buyer is a corporation
         duly organized, validly existing and in good standing under the laws of

         operate the properties currently owned and operated by it, and is duly
         qualified or licensed to do business and is in good standing as a
         foreign corporation authorized to do business in all jurisdictions in
         which the character of the properties owned or the nature of the
         business conducted by it would make such qualification or licensing
         necessary, including the State of New Mexico.

                  2.3.2. Agreement Authorized and its Effect on Other
         Obligations. The execution and delivery of this Agreement has been
         authorized by all necessary corporate, shareholder and other action on
         the part of Buyer, and this Agreement is the valid and binding
         obligation of Buyer enforceable against Buyer in accordance with its
         terms, except as enforceability may be limited by bankruptcy,
         insolvency, reorganization, debtor relief or similar laws affecting
         rights of creditors generally and subject to normal equitable
         principles. The execution, delivery and performance of this Agreement
         and the consummation of the transactions contemplated hereby, will not
         conflict with or result in a violation or breach of any term or
         provision of, nor constitute a default under (i) the charter or bylaws
         (or other organizational documents) of Buyer, (ii) any obligation,
         indenture, mortgage, deed of trust, lease, contract or other agreement
         to which Buyer is a party or by which Buyer or its properties are

         permits, certificate, writ, judgment, injunction, decree,
         determination, award or other decision of any court, arbitrator, or
         other governmental authority to which Buyer or any of its properties
         are subject, except, with respect to items (ii) and (iii), such
         violations, breaches, or defaults as would not have a Material Adverse
         Effect on Buyer, any Seller or the transactions contemplated by this
         Agreement.

                  2.3.3. Necessary Consents. No consent, approval or
         authorization of, or filing of a registration with, any governmental or
         regulatory authority, or any other person or entity is required to be
         made or obtained by Buyer in connection with the execution, delivery or
         performance of this Agreement or the consummation of the transactions
         contemplated hereby.

                  2.3.4. Investigations. Except as required pursuant to HSR, no
         investigation or review by any governmental entity with respect to the
         Buyer or any of the transactions contemplated by this Agreement is
         pending, or to knowledge of Buyer, threatened, nor has any governmental
         entity indicated to Buyer an intention to conduct the same.

         2.4.     Representations and Warranties of Key.  Key represents and 
warrants to each of the Sellers, COG and Coleman as follows:

                  2.4.1. Organization and Standing. Key is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of Maryland, has full requisite corporate power and authority to

         the Sellers, COG or Coleman, and the other parties to any other
         material agreements to which the Sellers, COG or Coleman are a party
         shall, when and to the extent necessary in the reasonable opinion of
         Buyer, have consented to the transaction contemplated hereby.

                  4.2.6. Assignment of Contracts and Issuance of Permits. All of
         the material Contracts shall have been assigned to Buyer. Buyer shall
         have received from the appropriate regulatory agencies all permits
         necessary for the operation of the Businesses as such Businesses have
         been conducted by the Sellers and COG, including permits of like tenor
         of the Sellers' Permits, or the Sellers' Permits shall have been
         assigned to the Buyer with the consent of the appropriate regulatory
         agencies.

                  4.2.7.  Environmental Assessments. The Sellers or COG shall 
         have caused, at their sole expense, a Phase I Environmental Site 
         Assessment of all real property being transferred or leased
         to the Buyer as contemplated by this Agreement and the Real
         Estate Contract. Such Environmental Site Assessment will be conducted
         in conformance with the scope and limitations of the ASTM Standard
         Practice E1527 by an environmental surveyor approved by the Buyer. At
         Buyer's reasonable request, the Sellers, COG or Coleman will cause, at
         their sole expense, a Phase II environmental site assessment to be
         conducted in conformance with the scope and limitations of the ASTM
         Standard Practice E1527 by an environmental surveyor approved by Buyer.
         The results of such Phase I and Phase II Environmental Site Assessments
         shall have revealed no environmental condition that would result in a
         Material Adverse Effect on the Sellers or materially reduce the value
         of the Real Estate.

         the Sellers in connection with the Businesses, other than the Real
         Estate, on such terms and conditions as is mutually acceptable to such
         party and Buyer.

         the Sellers.

                  5.1.2. By Buyer Because of Failure to Perform Agreements or

         and such condition has not been waived.

<PAGE>   29

                  5.1.6. By Buyer or by the Sellers if No Closing by November 1,
         1997. By either Buyer or the Sellers, if the Closing of the purchase
         and sale contemplated hereby shall not have been consummated on or
         before November 1, 1997 through no fault of any party hereto; provided,
         however, that this Agreement may not be terminated by any party hereto
         if the transactions contemplated hereby have not occurred due to the
         breach of any provision of this Agreement by the party desiring to
         terminate this Agreement.

         5.2. Effect of Termination. In the event of the termination and
abandonment of this Agreement pursuant to and in accordance with the provisions
of Section 5.1 hereof, this Agreement shall become void and have no effect,
without any liability on the part of any party hereto (or its stockholders or
controlling persons or directors or officers), except as otherwise provided in
this Agreement; provided, however, that a termination of this Agreement shall
not relieve any party hereto from any liability for damages incurred as a result
of a breach by such party of its representations, warranties, covenants,
agreements, or other obligations hereunder, occurring before such termination.

         5.3.  Waiver of Conditions.  Subject to the requirements of any

                                    ARTICLE 6

                              ADDITIONAL AGREEMENTS

         6.1. Noncompetition. Except as otherwise consented to or approved in
writing by Buyer, each of the Sellers, COG and Coleman, and their respective
affiliates, officers and directors agree that for a period of 60 months
following the Closing Date, such party will not (and in the case of Coleman will
cause any members of his family not to), directly or indirectly, acting alone or
as a member of a partnership or a holder of, or investor in as much as 5% of any
security of any class of any corporation or other business entity (i) engage in
any business on or after the Closing Date in competition with the businesses
conducted by any of the Sellers on or before the Closing Date, or in any service
business the services of which were provided and marketed by any of the Sellers
on or before the Closing Date in any state of the United States, or any foreign
country in which any of the Sellers transacted business on or before the Closing
Date; provided, however, that nothing in this Agreement will restrict any of the
above persons from pursuing oil and gas exploration and
production operations; (ii) request any present customers or suppliers of any of
the Sellers to curtail or cancel their business with Buyer (or Buyer's
affiliates); (iii) disclose to any person, firm or corporation any trade,
technical or technological secrets of Buyer (or Buyer's affiliates) or of the
Sellers or any details of their organization or business affairs or (iv) induce
or actively attempt to influence any employee of Buyer (or Buyer's affiliates)

                                       24
<PAGE>   30

to terminate his employment. The Sellers, COG and Coleman agree that if either
the length of time or geographical as set forth in this Section 6.1 is deemed
too restrictive in any court proceeding, the court may reduce such restrictions
to those which it deems reasonable under the circumstances, and such
restrictions as modified shall be enforceable hereunder. The obligations
expressed in this Section 6.1 are in addition to any other obligations that the
Sellers, COG and Coleman may have under the laws of any state requiring a
corporation selling its assets (or the shareholders of such corporation) to
limit its activities so that the goodwill and business relations being
transferred with such assets will not be materially impaired. The Sellers, COG
and Coleman further agree and acknowledge that Buyer does not have any adequate
remedy at law for the breach or threatened breach by the Sellers, COG or Coleman
of the covenants contained in this Section 6.1, and agree that Buyer may, in
addition to the other remedies which may be available to it hereunder, file a
suit in equity to enjoin the Sellers, COG or Coleman from such breach or
threatened breach. If any provisions of this Section 6.1 are held to be invalid
or against public policy, the remaining provisions shall not be affected
thereby. The Sellers, COG and Coleman acknowledge that the covenants set forth
in this Section 6.1 are being executed and delivered by such party in
consideration of the covenants of Buyer contained in this Agreement, and for
other good and valuable consideration, the receipt of which is hereby
acknowledged.

         6.2. Employees. Schedule 6.2 hereto is a complete and accurate listing
of all employees of the Sellers that devote their full time and effort in the
operation of the Assets and the conduct of the Business (the "EMPLOYEES"). Each
of the Sellers, COG and Coleman will use their best efforts to make all of their
Employees available for hire by the Buyer or its affiliates, and the Buyer
agrees to hire all of such Employees on the Closing Date, subject to such
Employees meeting Buyer's standard employment eligibility requirements and
mutual agreement between such Employees and Buyer as to their compensation
levels. Buyer shall have no liability or obligation with respect to any employee
benefits of any Employee except those benefits that accrue pursuant to such
Employees' employment with Buyer on or after the Closing Date. The Sellers, COG
and Coleman shall cooperate with Buyer in connection with any offer of
employment from Buyer to the Employees and use their best efforts to cause the
acceptance of any and all such offers. Except as provided in Section 4.2.9, all
Employees hired by Buyer shall be at-will employees of Buyer. Notwithstanding
any other provisions of this Agreement, this Section 6.2 shall not be deemed to
create any right or claim for the benefit of, and shall not be enforceable by,
any person which is not a party to this Agreement.

         6.3. Allocation of Purchase Price. The parties hereto agree to allocate
the purchase price paid by Buyer for the Assets hereunder as set forth on
Schedule 6.3 hereto, and shall report this transaction for federal income tax
purposes in accordance with the allocation so agreed upon. The parties hereto
for themselves and for their respective successors and assigns covenant and
agree that they will file coordinating Form 8594's in accordance with Section
1060 of the Internal Revenue Code of 1986, as amended, with their respective
income tax returns for the taxable year that includes the date hereof.

         6.4. Name Change. The Sellers shall, within ten days from the Closing
Date, cause to be filed (i) with the applicable agency of the Sellers' states of
organization an amendment to their charters (or other applicable organization
documents) of the Sellers changing the name of the Sellers from their current

                                       25
<PAGE>   31

names to names that are not similar to such names, and (ii) with the appropriate
authorities of the Sellers' states of organization and any other states such
documents as are required to effect such name change, including without
limitation, amendments or withdrawals of certificates of authority to do
business and assumed name filings. The Sellers shall, within five days from the
date of their receipt of confirmation of such filings from the applicable state
authorities, cause to be delivered to Buyer copies of all such confirmations.

         6.5. Further Assurances Relating to the Real Estate. Buyer and COG
agree that if the Title Commitment (as defined in the Real Estate Contract)
contains any Material Encumbrance (as defined in the Real Estate Contract), then
Buyer and COG shall in good faith either (i) negotiate an adjustment to the
Purchase Price (as defined in the Real Estate Contract) to reflect the
diminution in value of the Real Estate caused by such Material Encumbrance;
provided however that the Buyer shall not be required to purchase the Real
Estate under any circumstances that would prohibit the Buyer from operating the
Real Estate, without interference of any third party, in the same manner as the
Real Estate was operated by COG or (ii) enter into a lease with respect to the
Real Estate pursuant to which Buyer shall obtain use of the Real Estate
sufficient to operate such Real Estate, without interference of any third party,
in the same manner as the Real Estate was operated by COG. The provisions of
this Section 6.5 shall not relieve COG of its obligation under the Real Estate
Contract to use its best efforts to cure or remove all Material Encumbrances (as
defined in the Real Estate Contract).

         6.6. Further Assurances. From time to time, as and when requested by
any party hereto, any other party hereto shall execute and deliver, or cause to
be executed and delivered, such documents and instruments and shall take, or
cause to be taken, such further or other actions as may be reasonably necessary
to effect the transactions contemplated hereby.

                                    ARTICLE 7

                                 INDEMNIFICATION

         7.1. Indemnification by the Sellers, COG and Coleman. In addition to
any other remedies available to Buyer under this Agreement, or at law or in
equity, each of the Sellers, COG and Coleman shall, jointly and severally,
indemnify, defend and hold harmless Buyer and Key and their respective officers,
directors, employees, agents and stockholders, against and with respect to any
and all claims, costs, damages, losses, expenses, obligations, liabilities,
recoveries, suits, causes of action and deficiencies, including interest,
penalties and reasonable attorneys' fees and expenses (collectively, the
"DAMAGES") that such indemnitee shall incur or suffer, which arise, result from
or relate to (i) any breach of, or failure by the Sellers, COG or Coleman to
perform their respective representations, warranties, covenants or agreements in
this Agreement or in any schedule, certifi cate, exhibit or other instrument
furnished or delivered to Buyer by the Sellers, COG or Coleman under this
Agreement; and (ii) the Excluded Liabilities.



                                       26

<PAGE>   32



         7.2. Indemnification by Buyer and Key. In addition to any other
remedies available to the Sellers, COG and Coleman under this Agreement, or at
law or in equity, Buyer shall indemnify, defend and hold harmless the Sellers,
COG and Coleman against and with respect to any and all Damages that such
indemnitees shall incur or suffer, which arise, result from or relate to (i) any
breach of, or failure by Buyer or Key to perform, any of their respective
representations, warranties, covenants or agreements in this Agreement or in any
schedule, certificate, exhibit or other instrument furnished or delivered to
Sellers, COG or Coleman by or on behalf of Buyer or Key under this Agreement;
and (ii) the Assumed Liabilities.

         7.3. Indemnification Procedure. If any party hereto discovers or
otherwise becomes aware of an indemnification claim arising under Section 7.1 or
7.2 of this Agreement, such indemnified party shall give written notice to the
indemnifying party, specifying such claim, and may thereafter exercise any
remedies available to such party under this Agreement; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations hereunder, to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified party hereunder of written notice of the commencement
of any action or proceeding with respect to which a claim for indemnification
may be made pursuant to this Article 7, such indemnified party shall, if a claim
in respect thereof is to be made against any indemnifying party, give written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations hereunder, to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is brought against an indemnified party, the indemnifying party shall be
entitled to participate in and to assume the defense thereof, jointly with any
other indemnifying party similarly notified, to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party, and after such
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying party
has failed to assume the defense of such claim and to employ counsel reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim shall not be liable for the fees and expenses of
more than one counsel in any single jurisdiction for all parties indemnified by
such indemnifying party with respect to such claim or with respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations. Notwithstanding any of the foregoing to the contrary, the
indemnified party will be entitled to select its own counsel and assume the
defense of any action brought against it if the indemnifying party fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying party. No indemnifying party shall
consent to entry of any judgment or enter into any settlement with respect to a
claim without the consent of the indemnified party, which consent shall not be
unreasonably withheld, or unless such judgment or settlement includes as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability with respect to such claim. No
indemnified party shall consent to entry of any judgment or enter into any
settlement of any such action, the defense of which has been assumed by an
indemnifying party, without the consent of such indemnifying party, which
consent shall not be unreasonably withheld or delayed.

<PAGE>   33



         7.4. Limitation on Indemnification. The obligation of Sellers, COG and
Coleman to indemnify Buyer and Key for breach of a representation or warranty
pursuant to Section 7.1, and the obligation of Buyer and Key to indemnify the
Sellers, COG and Coleman for the breach of a representation or warranty pursuant
to Section 7.2, shall be limited as to amount as follows:

                  (i) the indemnifying party shall not be required to indemnify
         the indemnified party for any Damages not related to environmental
         matters (the "NON-ENVIRONMENTAL DAMAGES") except to the extent the
         aggregate amount of all such Non-Environmental Damages exceeds
         $250,000; and

                  (ii) neither the Sellers, COG, Coleman shall be required to
         indemnify Buyer or Key for any Damages relating to the breach of a
         representation or warranty contained in Section 2.1.14 (Environmental
         Matters) (the "ENVIRONMENTAL DAMAGES") except to the extent the
         aggregate amount of all such Environmental Damages exceeds $250,000.

                  (iii) for purposes of the indemnification obligations set
         forth in this Section 7.4, all representations, warranties and
         covenants set forth in this Agreement shall be assumed to be free of
         qualifications with respect to materiality.


                                    ARTICLE 8

                                  MISCELLANEOUS

         8.1. Materiality. "MATERIAL ADVERSE EFFECT" when used in this Agreement
shall mean any adverse effect on the business, operations, assets or financial
condition or results of operations of the party or parties at issue unless such
effect either can reasonably be expected to result in less than a $250,000
effect on the financial condition or results of operations, or the effect is due
to general changes in the economy or the general industry in which the party at
issue operates.

         8.2. Survival of Representations, Warranties and Covenants. All
representations, warranties, covenants and agreements made by the parties hereto
shall survive indefinitely without limitation, notwithstanding any investigation
made by or on behalf of any of the parties hereto; provided, however, that all
representations and warranties of each party hereto shall terminate on the
second anniversary of the Closing Date except (i) as to representations and
warranties contained in Section 2.1.6 with respect to title to the Assets which
shall continue and survive indefinitely, and (ii) as to the representations and

                                       28
<PAGE>   34

warranties contained in Section 2.1.21 (Taxes), which shall continue and survive
for the full period of the applicable statutes of limitation (giving effect to
any waiver or extension thereof). All claims for indemnification by any party
hereto with respect to a breach of a representation or warranty must be asserted
in writing with specificity prior to the expiration of the applicable survival
period. All statements contained in any certificate, schedule, exhibit or other
instrument delivered pursuant to this Agreement shall be deemed to have been
representations and warranties by the respective party or parties, as the case
may be, and shall also survive subject to the limitations stated above despite
any investigation made by any party hereto or on its behalf.

         8.3.     Entirety.  This Agreement embodies the entire agreement among
the parties with respect to the subject matter hereof, and all prior agreements
between the parties with respect thereto are hereby superseded in their 
entirety.

         8.4.     Counterparts.  Any number of counterparts of this Agreement 
may be executed and each such counterpart shall be deemed to be an original 
instrument, but all such counterparts together shall constitute but one 
instrument.

         8.5.     Notices and Waivers.  Any notice or waiver to be given to any
party hereto shall be in writing and shall be delivered by courier, sent by 
facsimile transmission or first class registered or certified mail, postage 
prepaid, return receipt requested:

                  documents referred to in the Title Commitment ("TITLE
                  COMMITMENT DOCUMENTS").

                  b. Within fifteen (15) days after a request from Purchaser,
         Seller, at its sole cost and expense, shall deliver to Purchaser an
         updated survey ("SURVEY") consisting of a plat and field notes prepared
         by a licensed surveyor acceptable to Purchaser and Title Company,
         which Survey shall (i) reflect the actual dimensions of, and area
         within, the Land, the location of any easements, setback lines,
         encroachments, or overlaps thereon or thereover, and the outside

         Title Company to delete the printed exception for "discrepancies,

         any overlapping of improvements" in the Owner's Title Policy to be
         delivered pursuant to Section 9 hereof, (vi) reflect any area within
         the Land that has been designated by the Federal Insurance

         agency or body as being subject to special or increased flooding
         hazards, and (vii) in general, comply with the requirements for an ALTA
         survey. For purposes of the property description to be included in the
         general warranty deed to be delivered pursuant to Section 9 hereof, the
         field notes prepared by the surveyor shall control any conflicts or
         inconsistencies with Exhibit A hereto, and such field notes shall be
         incorporated herein by this reference upon their completion and
         approval by Purchaser.

                  c. Within fifteen (15) days after the Effective Date of this
         Agreement, Seller, at its sole cost and expense, shall deliver to
         Purchaser current searches of all Uniform Commercial Code financing
         statements filed with the Office of the Secretary of State of New
         Mexico and the County Clerk of San Juan County, New Mexico against
         Seller and Seller's predecessors in title reflecting all effective
         financing statements then of record relating to the Property or any
         part thereof.

                  d. Within fifteen (15) days after the Effective Date of this
         Agreement, Seller, at its sole cost and expense, shall deliver to
         Purchaser (i) legible copies of all Property Agreements; (ii) copies of
         all engineering and technical reports in the possession of Seller or
         its representatives that concern the Land or Improvements, including
         oils testing reports and reports of environmental or hazardous waste
         inspections or surveys; (iii) copies of all plans and specifications
         that describe or relate to the Improvements; and (iv) profit and loss
         statements reflecting the results of operation of the Property for the
         preceding year. The documents described in this Section 5(d) are herein
         collectively called the "DOCUMENTS", and the information contained in
         the Documents is herein collectively called the "INFORMATION".

         Section 6. Right of Inspection; Contingency Period. From the Effective
Date to the Closing Date, Seller shall afford Purchaser and its representatives
a continuing right to inspect, at reasonable hours, the Property, and all books,

                                       3

operation, or maintenance of the Property; provided, however, that in conducting
its inspection Purchaser shall not unreasonably interfere with the business and
operations of the Seller.

         Section 7. Title. Purchaser shall have the right, within ten (10) days
after receipt of the last of the Title Commitment, Title Documents, Survey, UCC
search and Documents, to object in writing to any Material Encumbrances (as
hereinafter defined) reflected by the Title Commitment, Survey or UCC search. If
a notice of objection is not given during such ten (10) day period, then it

shall be deemed that all matters reflected by the Survey and Title Commitment
are "PERMITTED ENCUMBRANCES". Seller shall use reasonable efforts, at its sole
cost, to cure or remove all Material Encumbrances and give Purchaser written
notice thereof before Closing; provided, however, that Seller, at its sole cost,
shall be obligated to cure or remove at or before Closing all mortgages, deeds
of trust, judgment liens, mechanics and materialmen's liens, and other liens
against the Property, whether or not Purchaser objects thereto. Further, Seller
shall cause any leases relating to the Land and Improvements to be terminated on
or before Closing. If Seller does not timely cause all of the Material
Encumbrances to be removed or cured, and timely written notice thereof to be
given to Purchaser, then Purchaser shall have the right to either (i) terminate
this Agreement in accordance with Section 12(b) hereof by delivering notice to
Seller, or (ii) attempt to remove or cure the Material Encumbrances and deduct
the cost of such removal or cure from the Purchase Price, or (iii) elect to
purchase the Property subject to the Material Encumbrances, other than liens
that Seller is obligated to cure or remove, and the Material Encumbrances (other
than liens that Seller is obligated to cure or remove) subject to which
Purchaser elects to purchase the Property shall thereafter be Permitted
Encumbrances, and with a reduction in the Purchase Price to reflect the
diminution in value of the Property. For the purposes of this Agreement, a
"MATERIAL ENCUMBRANCE" shall mean a lien, or an encumbrance on the Property
which affects Seller's ability to convey good, marketable and indefeasible title
to the Property to Purchaser or materially interferes with Purchaser's intended
use of the Property.

         Section 8. Seller's Representations, Warranties, and Covenants. Seller
hereby represents and warrants to, and covenants with, Purchaser that:

                  a. Seller has full right, power, and authority to execute and
         deliver this Agreement and to consummate the purchase and sale
         transactions provided for herein without obtaining any further consents
         or approvals from, or the taking of any other actions with respect to,
         any third parties. This Agreement, when executed and delivered by
         Seller and Purchaser, will constitute the valid and binding agreement
         of Seller, enforceable against Seller in accordance with its terms.

                  b. Seller has good, marketable and indefeasible title in fee
         simple to the Land and Improvements, free and clear of all liens
         (except those liens that will be released at or before Closing), and no
         party, except as herein set forth, has or shall have on the Closing
         Date any rights in, or to acquire, the Property.

                  c. The Land is not located within an area that has been
         designated by the Federal Insurance Administration, the Army Corps of
         Engineers, or any other governmental agency or body as being subject to
         special flooding hazards.

                                       4
<PAGE>   6

                  d. Seller is the owner of all Personalty free and clear of all
         material liens, claims or encumbrances, except liens and security
         interests that will be released at or before Closing.

                  e. The copies of all Documents, Title Commitment Documents 
         and other documents delivered by or on behalf of Seller to Purchaser 
         pursuant to this Agreement shall be true and complete in all material 
         respects and, to the best of Seller's knowledge and belief, the 
         information shall be true and complete in all material respects.

                  f. There are no actions, suits, claims, assessments, or
         proceedings pending or, to the knowledge of Seller, threatened that
         could materially adversely affect the ownership, operation, or
         maintenance of the Property or Seller's ability to perform hereunder.

                  g. All bills and other payments due with respect to the
         ownership, operation, and maintenance of the Property have been paid or
         to be paid prior to Closing in the ordinary course of business.

                  h. From the Effective Date until the Closing Date, Seller
         shall: (i) operate the Property in a good and businesslike manner in
         accordance with good and prudent business practices; (ii) continue all
         Property Agreements, and insurance policies or contracts relative to
         the Property in full force and effect and neither cancel, amend, nor
         renew any of the same without Purchaser's prior written consent; (iii)
         not commit or permit to be committed any waste to the Property; (iv)
         not, without the prior written consent of Purchaser, enter into any
         agreement or instrument or take any action that would encumber the
         Property after Closing, that would bind Purchaser or the Property after
         Closing, or that would be outside the normal scope of maintaining and
         operating the Property; and (v) not remove any item of the Personalty
         from the Land or Improvements unless it is replaced with an item of at
         least equal value that is properly suited for its intended purpose.

                  i. There are no labor disputes, organizational campaigns, or
         union contracts existing or under negotiation with respect to the
         Property or the operation thereof. There are no employees engaged in
         the operation or maintenance of the Property for whom Purchaser will be
         responsible after Closing.

                  j. Attached hereto as Exhibit C is a complete and correct list
         of all Property Agreements setting forth the identity of the parties
         thereto, the date of such agreement, the consideration payable
         thereunder, the services to be rendered thereunder, and the expiration
         date thereof. Except as otherwise expressly indicated on Exhibit C, all
         of the Property Agreements are cancelable on thirty (30) or fewer days
         notice, without payment of any cancellation consideration.

                  k. None of the current or past operations of the Property is
         being or has been conducted or used in such a manner as to constitute a
         violation of any Environmental Law (defined below) that would or might
         result in a Material Adverse Effect (defined below). The Seller has not
         received any notice (whether formal or informal, written or oral) from

                                       5
<PAGE>   7

         any entity, governmental agency or individual regarding any existing,
         pending or threatened investigation or inquiry related to violations of
         any Environmental Law or regarding any claims for remedial obligations
         or contribution for removal costs or damages under any Environmental
         Law. There are no writs, injunction decrees, orders or judgments
         outstanding, or lawsuits, claims, proceedings or investigations pending
         or, to the knowledge of Seller, threatened, relating to the ownership,
         use, maintenance or operation of the Property, nor, to the knowledge of
         any of Seller, is there any basis for any of the foregoing.
         Purchaser will not be required to obtain any permits, licenses or
         similar authorizations pursuant to any Environmental Law after the
         Closing Date to operate and use any of the Property for their current
         or proposed purposes and uses, except for permits, licenses or similar
         authorizations that would not have a Material Adverse Effect. The
         Property includes all environmental and pollution control equipment
         necessary for material compliance with applicable Environmental Law.
         Except as disclosed in Schedule 8(k) hereof, (i) no Hazardous Materials
         (defined below) have been or are currently being used by Seller in the
         operation of the Property, (ii) no Hazardous Materials are or have ever
         been situated in, on or under the Property, (iii) there are no, and
         there have never been any, underground storage tanks (as defined under
         Environmental Law) located under the Property, and (iv) there are no
         environmental conditions or circumstances, including the presence or
         release of any Hazardous Materials, on the Property, or on any property
         on which Hazardous Materials generated by Seller's operations or the
         use of the Property were disposed of, to the extent any of the above
         individually or in the aggregate would or might result in a Material
         Adverse Effect. The term "ENVIRONMENTAL LAW" means any and all laws,
         rules, orders, regulations, statutes, ordinances, codes, decrees, and
         other legally enforceable requirements (including, without limitation,
         common law) of the United States, or any state, regional, city, local,
         municipal or other governmental authority or quasi-governmental
         authority, regulating, relating to, or imposing environmental standards
         of conduct concerning protection of the environment or human health, or
         employee health and safety as from time to time has been or is now in

                  l. The current zoning classification of the Property is
         small commercial and light industrial; the Improvements have been

         therewith; and there are no proceedings pending or contemplated to 
         alter such zoning classification.

If (i) any of Seller's representations and warranties set forth in this Section
8 are untrue in any material respect, or (ii) at any time at or before Closing
there is any material change with respect to the matters represented and
warranted by Seller pursuant to this Section 8, then Seller shall give Purchaser
prompt written notice thereof, and Purchaser shall have the right to terminate

                  Company, made payable to the order of Seller, or immediately
                  available cash funds, in the amount of the Purchase Price as
                  specified in Section 2 hereof, adjusted in accordance with

                  Company that the person executing the Closing documents on

                  Permitted Encumbrances;

                           ii. Bill of Sale and Assignment in the form of

                  other than the Land and Improvements, to Purchaser, subject 
                  only to the Permitted Encumbrances;

                           iii. Owner's Policy of Title Insurance in the amount
                  of the Purchase Price issued by Title Company (with such
                  reinsurance as Purchaser may require), insuring that Purchaser
                  is the owner of the Land and Improvements subject only to the
                  Permitted Encumbrances and the standard printed exceptions
                  included in an ALTA standard form owner's policy of title
                  insurance; provided, however, that (A) the standard exception
                  for discrepancies, conflicts, or shortages in area shall be
                  deleted; (B) such policy shall have "None of Record" endorsed
                  regarding restrictions except for restrictions that are
                  Permitted Encumbrances; (C) the rights of parties in


                                       7
<PAGE>   9

                  possession shall be limited only to those holding under
                  written leases; (D) the standard exception for taxes shall be
                  limited to the year in which the Closing occurs, marked "not
                  yet due and payable", and subsequent years and subsequent
                  assessments for prior years due to change in land usage or
                  ownership; and (E) the Owner's Policy shall provide
                  comprehensive coverage, lien coverage and gap coverage;

                           iv. Current certificate issued by company acceptable
                  to Purchaser reflecting that since the date of the 
                  searches furnished pursuant to Section 5(c) hereof no Uniform
                  Commercial Code filings, chattel mortgages, assignments, 
                  pledges, or other encumbrances have been filed in the offices
                  of the Secretary of State of the State of New Mexico or the 
                  County Clerk of San Juan County with reference to the 
                  Property;

                           v. Evidence satisfactory to Purchaser and the Title 
                  Company that the persons executing and delivering the Closing
                  documents on behalf of Seller have full right, power and 
                  authority to do so;

                           vi. Certificate executed by Seller stating that, as 
                  of the Closing Date, each of Seller's representations and 
                  warranties set forth in Section 8 hereof is true and
                  correct;

                           vii. Certificate meeting the requirements of Section
                  1445 of the Internal Revenue Code of 1986, as amended,
                  executed and sworn to by Seller; and

                           viii. Such other instruments as are customarily
                  executed in New Mexico to effectuate the conveyance of
                  property similar to the Property, with the effect that, after
                  the Closing, Purchaser will have succeeded to all of the
                  rights, titles, and interests of Seller related to the
                  Property and Seller will no longer have any rights, titles, or
                  interests in and to the Property.

                  c. All normal and customarily proratable items, including
         without limitation real estate and personal property taxes, utility
         bills, rents, interest, and Property Agreement payments shall be
         prorated as of the Closing Date, Seller being charged and credited for
         all of same up to such date and Purchaser being charged and credited
         for all of same on and after such date. If the actual amounts to be
         prorated are not known as of the Closing Date, the prorations shall be
         made on the basis of the best evidence then available, and thereafter,
         when actual figures are received, a cash settlement will be made
         between Seller and Purchaser. The provisions of this Section 9(c) shall
         survive the Closing.

                  d. Seller shall pay all costs and liabilities relating to the
         Property that arise out of or are attributable to the period prior to
         the Closing Date, and shall indemnify and hold harmless Purchaser from
         such costs and liabilities and from all reasonable attorneys' fees
         expended by Purchaser in connection therewith; provided, however, that
         Seller's obligations under this indemnity shall be subject to the
         provisions of Paragraph 8(k). Seller shall have the right to receive
         all proceeds relating to the Property that are properly allocable to

                                       8
<PAGE>   10

         the period before the Closing Date, and Purchaser shall have the right
         to receive all proceeds relating to the Property that are properly
         allocable to the period from and after the Closing Date. Purchaser
         shall pay all costs and liabilities relating to the Property that arise
         out of or are attributable to the period from and after the Closing
         Date, except such costs and liabilities that arise out of or result
         from a breach by Seller of its representations and warranties set forth
         in Section 8 hereof, and Purchaser shall indemnify and hold harmless
         Seller from such costs and liabilities and from all reasonable
         attorneys' fees expended by Seller in connection therewith. This
         Section 9(d) shall survive the Closing.

                  e. Upon completion of the Closing, Seller shall deliver to
         Purchaser possession of the Property free and clear of all tenancies of
         every kind and parties in possession, with all parts of the Property
         (including without limitation the Improvements and Personalty) in the
         same condition as on the date hereof, normal wear only excepted.

         Section 10. Commissions. Seller shall defend, indemnify, and hold
harmless Purchaser, and Purchaser shall defend, indemnify, and hold harmless
Seller, from and against all claims by third parties for brokerage, commission,
finders, or other fees relative to this Agreement or the sale of the Property,
and all court costs, attorneys' fees, and other costs or expenses arising
therefrom, and alleged to be due by authorization of the indemnifying party.

         Section 11. Destruction, Damage or Taking Before Closing. If, before
Closing, all or any part of the Land, Minerals, Utilities, Improvements or
Personalty are destroyed or damaged, or become subject to condemnation or
eminent domain proceedings, then Seller shall promptly notify Purchaser thereof.
Purchaser shall have the right to terminate this Agreement or may elect to
proceed with the Closing (subject to the other provisions of this Agreement). In
the event Purchaser elects to proceed to Closing, Purchaser shall be entitled to
all insurance proceeds or condemnation awards payable as a result of such damage
or taking and, to the extent the same may be necessary or appropriate, Seller
shall assign to Purchaser at Closing Seller's rights to such proceeds or awards.
If, within ten (10) business days of receipt of Seller's notice respecting the
damage, destruction, or taking, Purchaser notifies Seller of its intent to
terminate this Agreement, then this Agreement shall be deemed terminated
pursuant to Section 12(b) hereof.

         Section 12.       Termination and Remedies.

                  a. If Purchaser fails to consummate the purchase of the
         Property pursuant to this Agreement for any reason other than
         termination hereof pursuant to a right granted to Purchaser in Sections
         6, 7, 8, 11 and 13 hereof, then Seller, as its sole remedies, shall
         have the right to: (i) terminate this Agreement by notifying Purchaser
         thereof, in which event Title Company shall deliver the Earnest Money
         to Seller as liquidated damages, whereupon neither Purchaser nor Seller
         shall have any further rights or obligations hereunder, or (ii) enforce
         specific performance of the obligations of Purchaser hereunder.

                  b. If Purchaser terminates this Agreement pursuant to Section
         6, 7, 8, 11 or 13 hereof, then Title Company shall return the Earnest
         Money to Purchaser, whereupon neither party hereto shall have any
         further rights or obligations hereunder.


                                       9
<PAGE>   11

                  c. If Seller fails to consummate the sale of the Property
         pursuant to this Agreement for any reason other than termination hereof
         pursuant to Section 13, Purchaser's failure to perform its obligations
         hereunder or termination hereof by Purchaser in accordance with Section
         12(b), then Purchaser, as its sole remedies, shall have the right to:
         (i) terminate this Agreement by notifying Seller thereof, in which case
         Title Company shall return the Earnest Money to Purchaser and neither
         party hereto shall have any further rights or obligations hereunder; or
         (ii) enforce specific performance of the obligations of Seller
         hereunder.

                  d. Seller and Purchaser hereby acknowledge and agree that they
         have included the provision for payment of liquidated damages in
         Section 12(a) because, in the event of a breach by Purchaser, the
         actual damages to be incurred by Seller can reasonably expected to
         approximate the amount of liquidated damages called for herein and
         because the actual amount of such damages would be difficult if not
         impossible accurately to measure.

         Section 13. Consideration. A material part of the consideration to the
Seller for selling is that the Seller has the option to qualify this transaction
as part of a tax deferred exchange under Section 1031 of the Internal Revenue
Code. Buyer agrees to cooperate in the exchange provided Buyer incurs no
additional liability, cost or expense.

         Section 14. Conditions to Closing. This Agreement is expressly
conditioned upon the consummation of an Asset Purchase Agreement dated on or
about September 2, 1997, between Purchaser, Key Energy Group, Inc., Seller, Big
A Well Service Co., Sunco Trucking Co. and Justis Supply Co., Inc. (the "ASSET
PURCHASE AGREEMENT"). In the event the Asset Purchase Agreement is not
consummated for any reason, Seller shall have no further obligation to sell and
Purchaser shall have no further obligation to purchase the Property and this
Agreement shall be automatically terminated and of no further force and effect.

         Section 15. Notices. All notices provided or permitted to be given
under this Agreement must be in writing and may be served by depositing same in
the United States mail, addressed to the party to be notified, postage prepaid
