Execution Copy NON-COMPETE AGREEMENT This AGREEMENT (the "Agreement"), dated as of October 20, 1998, by and among Key Energy Group, Inc., a Maryland corporation ("Parent"), and Joseph B. Eustace ("Mr. Eustace"). WHEREAS, Mr. Eustace previously held the position of Vice President of East Texas/Gulf Coast Region of Dawson Production Services, Inc., a Texas corporation (the "Company"); WHEREAS, pursuant to an Agreement and Plan of Merger, dated as of August 11, 1998, by and among Parent, Midland Acquisition Corp., a New Jersey corporation (the "Purchaser"), and the Company (the "Merger Agreement"), at the Effective Time (as defined in the Merger Agreement) the Purchaser will be merged with and into the Company (the "Merger"), and the Company will become a subsidiary of Parent; and WHEREAS, Mr. Eustace entering into this Agreement is a material inducement to Parent and the Purchaser to enter into the Merger Agreement; NOW, THEREFORE, in consideration of the foregoing and the mutual covenants, representations, agreements, and promises set forth herein, and intending to be legally bound, the parties agree as follows: 1. Covenant Not to Compete; No Solicitation. In addition to any limitation on competition contained in any employment agreement that Mr. Eustace may enter into with Parent, during that period of time (the "Term") beginning on the date hereof and ending on October 19, 2001, other than pursuant to an employment agreement with Parent, Mr. Eustace shall not, in the Continental United States, directly or indirectly engage in the following businesses: (i) workover rig services, including completion of new wells, maintenance and recompletion of existing wells (including horizontal recompletions) and plugging and abandonment of wells at the end of their useful lives; (ii) liquid services, including vacuum truck services, frac tank rental and salt water injection; and/or (iii) production services, including well test analysis, pipe testing, slickline wireline services and fishing and rental tool services. Without limiting the generality of the foregoing, Mr. Eustace shall not interfere with the business or accounts of Parent and its subsidiaries and affiliates, including the making of any statements or comments of a defamatory or disparaging nature to third parties regarding Parent or its subsidiaries or affiliates or their respective officers, directors, personnel, products or services. Mr. Eustace agrees that during the Term, he will not hire or solicit to hire, directly or indirectly, any employee of Parent or its subsidiaries or affiliates, or otherwise solicit, directly or indirectly, any employee of Parent or its subsidiaries or affiliates to leave the employ of Parent or its subsidiaries or affiliates. 2. Consideration. In exchange for Mr. Eustace's covenants contained in Section 1 hereof, Parent shall pay, or cause to be paid to, Mr. Eustace an annual amount of $75,000, payable in equal monthly installments (subject to proration for any partial period) on the last day of each month of the Term to an account designated in writing by Mr. Eustace. The payor may make any tax withholding it deems to be necessary under applicable tax laws. Mr. Eustace acknowledges that the consideration described in this Section 2 is adequate, fair and reasonable. 3. Reasonableness of Covenant Not to Compete; Irreparable Injury. Mr. Eustace acknowledges that this Agreement is being entered into in connection with the consummation of the transactions contemplated by the Merger Agreement, that the agreements contained herein are of a special and unique character, which gives this Agreement a peculiar value to Parent, the loss of which may not be reasonably or adequately compensated for by damages in an action at law, and that a material breach or threatened breach by him of any of the provisions contained in this Agreement will cause Parent irreparable injury. Mr. Eustace therefore agrees that Parent shall be entitled, in addition to any other right or remedy, to a temporary, preliminary and permanent injunction, without the necessity of proving the inadequacy of monetary damages or the posting of any bond or security, enjoining or restraining Mr. Eustace from any such violation or threatened violations. 4. Arbitration. Any dispute between the parties arising out of this Agreement, including but not limited to any dispute regarding any aspect of this Agreement, its formation, validity, interpretation, effect, performance or breach ("arbitrable dispute") shall be submitted to arbitration in the cities of Houston or San Antonio, Texas, before an experienced arbitrator who is either licensed to practice law in Texas, or is a retired judge. The parties agree to make a good faith effort to select a mutually agreeable arbitrator. However, if the parties are unable to reach agreement on an arbitrator, one will be selected pursuant to the commercial rules of the American Arbitration Association or any successor rules thereto. The arbitration shall be conducted in accordance with the commercial rules of the American Arbitration Association or any successor rules. The arbitrator in any arbitrable dispute shall not have authority to modify or change this Agreement in any respect except to the extent set forth in Section 5.6 hereof. The prevailing party in any such arbitration shall be awarded its costs, expenses, and reasonable attorneys' fees incurred in connection with the arbitration in an aggregate amount not to exceed $25,000. Mr. Eustace and Parent shall each be responsible for payment of one-half of the amount of any arbitrator's fee(s) payable prior to the existence of a prevailing party, such amounts to be repaid to the prevailing party pursuant to the previous sentence. The arbitrator's decision and/or award will be fully enforceable and subject to an entry of judgment by any court of competent jurisdiction. 5.

No waiver shall be deemed to have occurred unless set forth in a writing executed by or on behalf of the waiving party. No such written waiver shall be deemed a continuing waiver unless specifically stated therein, and each such waiver shall operate only as to the specific term or condition waived and shall not constitute a waiver of such term or condition for the future or as to any act other than that specifically waived. 5.4 Notices.

If for any reason any term or provision of this Agreement is held to be invalid or unenforceable, all other valid terms and provisions hereof shall remain in full force and effect, and all of the terms and provisions of this Agreement shall be deemed to be severable in nature. If for any reason any term or provision containing a restriction set forth herein is held to cover an area or to be for a length of time which is unreasonable, or in any other way is construed to be too broad or to any extent invalid, such term or provision shall not be determined to be null, void and of no effect, but to the extent the same is or would be valid or enforceable under applicable law, any court of competent jurisdiction shall construe and interpret or reform this Agreement to provide for a restriction having the maximum enforceable area, time period and other provisions (not greater than those contained herein) as shall be valid and enforceable under applicable law. 5.6 Amendment.
