All contracts, leases, plans or other arrangements to which TST is a party, by which it is bound or to which TST or the assets of TST are subject are in full force and effect, and constitute valid and binding obligations of TST and the other parties thereto.

No contract has been entered into on terms which could reasonably be expected to have a materially adverse effect on TST. Neither of the Shareholders has received any information which would cause such Shareholder to conclude that any customer of TST will (or is likely to) cease doing business with TST (or any successors thereto) as a result of the consummation of the transactions contemplated hereby.

The Shareholders will use their reasonable best efforts to cause the TST Employees to remain in the employment of TST through the Closing Date. Key will cause TST to continue the employment of the TST Employees; provided, however, nothing herein shall be construed as creating any contractual obligation of TST to continue any such employee as an employee of TST. 7.4 Employee Benefit Plans.

Each of the Shareholders agrees that for a period of five (5) years from the Closing Date, such Shareholder will not, directly or indirectly, acting alone or as a member of a partnership or as an officer, director, employee, consultant, representative, holder of, or investor in as much as 3% of any security of any class of any corporation or other business entity (i) engage in competition with the business or businesses conducted by TST, Key or any affiliate of Key as of the Closing Date, or in any service business the services of which are provided and marketed by TST, Key or any affiliate of Key as of the Closing Date in Texas or New Mexico; (ii) request any present customers or suppliers of TST to curtail or cancel their business with TST, Key or any affiliate of Key; (iii) disclose to any person, firm or corporation any trade, technical or technological secrets of TST, Key or any affiliate of Key or any details of their organization or business affairs or (iv) induce or actively attempt to influence any employee of TST, Key or any affiliate of Key to terminate his employment. Each of the Shareholders agrees that if either the length of time or geographical area set forth in this Section 7.5 is deemed too restrictive in any court proceeding, the court may reduce such restrictions to those which it deems reasonable under the circumstances. The obligations expressed in this Section 7.5 are in addition to any other obligations that the Shareholders may have under the laws of the State of Texas requiring an employee of a business or a shareholder who sells his stock in a corporation (including a disposition in a merger) to limit his activities so that the goodwill and business relations of his employer and of the corporation whose stock he has sold (and any successor corporation) will not be materially impaired. Each of the Shareholders further agrees and acknowledges that TST, Key and its affiliates do not have any adequate remedy at law for the breach or threatened breach by such Shareholder of this covenant, and agree that TST, Key or any affiliate of Key may, in addition to the other remedies which may be available to it hereunder, file a suit in equity to enjoin such Shareholder from such breach or threatened breach. If any provisions of this Section 7.5 are held to be invalid or against public policy the remaining provisions shall not be affected thereby. Each of the Shareholders acknowledges that the covenants set forth in this Section 7.5 are being executed and delivered by such Shareholder in consideration of the covenants of Key contained in this Agreement, and for other good and valuable consideration, receipt of which is hereby acknowledged. 7.6 Material Adverse Change. As used in this Agreement, the term "material adverse change" means any change, event, circumstance or condition (collectively, a "Change") which when considered with all other Changes would reasonably be expected to result in a "loss" having the effect of so fundamentally adversely affecting the business or financial prospects of Key or TST, as the case may be, that the benefits reasonably expected to be obtained by Key or TST, as the case may be, as a result of the consummation of the transactions contemplated by this Agreement would be jeopardized with relative certainty. The term "loss" shall mean any and all direct or indirect payments, obligations, assessments, losses, loss of income, liabilities, fines, penalties, costs and expenses paid or incurred or more likely than not to be paid or incurred, or diminutions in value of any kind or character (whether known or unknown, conditional or unconditional, choate or inchoate, liquidated or unliquidated, secured or unsecured, accrued, absolute, contingent or otherwise) that are more likely than not to occur, including without limitation penalties, interest on any amount payable to a third party as a result of the foregoing and any legal or other expenses reasonably incurred or more likely than not to be incurred in connection with investigating or defending any demands, claims, actions or causes of action that, if adversely determined, would likely result in losses, and all amounts paid in settlement of claims or actions; provided, that losses shall be net of any recoveries by TST from third parties and any insurance proceeds TST is entitled to receive from a non-affiliated insurance company on account of such losses (after taking into account any costs incurred in obtaining such proceeds and any increase in insurance premiums as a result of a claim with respect to such proceeds). 7.7 Shareholder Employment. After the Closing Date, Keith Neill shall remain in the employment of TST at a monthly salary of $8,000. ARTICLE 8 INDEMNIFICATION 8.1 Indemnification by the Shareholders. In addition to any other remedies available to Key under this Agreement, or at law or in equity, each of the Shareholders shall jointly and severally indemnify, defend and hold harmless Key, and its 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") in excess of $150,000.00 in the aggregate that such indemnitees shall incur or suffer, which arise, result from or relate to any breach of, or failure by, the Shareholders to perform, their respective representations, warranties, covenants or agreements in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to Key by the Shareholders under this Agreement; provided, however, that (i) the Shareholders' aggregate obligations to indemnify Key and the other parties identified above shall never exceed the aggregate sum of $8,500,000.00; (ii) the Shareholders shall not be required to so indemnify, defend and hold harmless Key and its officers, directors, employees, agents and stockholders, against and with respect to any Damages incurred as a result of a breach by either of the Shareholders of their respective representations and warranties in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to Key by any of the Shareholders under this Agreement for which Key fails to provide written notice of a claim for such Damages to the Shareholders on or before the expiration of the survival period (as specified in Section 9.2 hereof) of the specific representation or warranty alleged to have been breached; (iii) in the event that Key can recover Damages for which it is indemnified by the Shareholders pursuant to this Section 8.1 from a collateral source including, but not limited to, a third party or insurance coverage, and does in fact collect all or a portion of such Damages from such collateral source, then Key agrees not to enforce its right to indemnification under this Section 8.1 to the extent of such third party collections; and (iv) Key agrees that it will not seek indemnification under this Section 8.1 for any environmental remedial work on TST's properties unless TST (or Key) is required to perform such work by a third party or by a governmental entity or agency. 8.2 Indemnification by Key. In addition to any other remedies available to the Shareholders under this Agreement, or at law or in equity, Key shall indemnify, defend and hold harmless each of the Shareholders against and with respect to any and all Damages in excess of $150,000.00 in the aggregate that such indemnitees shall incur or suffer, which arise, result from or relate to any breach of, or failure by Key to perform, any of its representations, warranties, covenants or agreements in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to the Shareholders by or on behalf of Key under this Agreement; provided, however, that (i) Key's aggregate obligation to indemnify the Shareholders shall never exceed the sum of $8,500,000.00; (ii) Key shall not be required to so indemnify, defend and hold harmless the Shareholders and their employees and agents against and with respect to any Damages incurred as a result of a breach by Key of any of its representations and warranties in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to the Shareholders by Key under this Agreement for which the Shareholders fail to provide written notice of a claim for such Damages to Key on or before the expiration of the survival period (as is specified in Section 9.2 hereof) of the specific representations or warranty alleged to have been breached; and (iii) in the event that the Shareholders can recover Damages for which it is indemnified by Key pursuant to this Section 8.1 from a collateral source including, but not limited to, a third party or insurance coverage, and does in fact collect all or a portion of such Damages from such collateral source, then the Shareholders agree not to enforce its right to indemnification under this Section 8.2 to the extent of such third party collections. 8.3 Indemnification Procedures. If any party hereto discovers or otherwise becomes aware of a claim for Damages arising under this Article 8, 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 Damages arising under Sections 8.1 or 8.2 hereof may be made, 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. Any 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, and the expenses of such defense shall 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. 8.4 Litigation Indemnification. The parties hereto acknowledge that TST is a defendant in Cause No. H-96-0163 pending in the United States District Court for the Southern District of Texas, Houston Division, entitled AMERADA HESS CORPORATION VS. T.S.T. PARAFFIN SERVICE COMPANY, INC. (the "Amerada Hess Litigation"). The parties hereto further acknowledge that there are collateral matters which are being litigated insofar as the validity of an indemnity agreement executed as a result of settlement by TST in Cause No. C-2244-94-D pending in the 206th Judicial District Court of Hidalgo County, Texas, which involved Regina Valenzuela as Next Friend of Brenda Janette Montanez. The parties hereto further acknowledge that TST has remaining upon its insurance coverage the sum of $250,000 which can be applied toward any damages awarded in the Amerada Hess Litigation or which may be used to help fund a settlement of this litigation. In addition to any other remedies available to the parties hereto under this Agreement, or at law or in equity, the parties hereto hereby agree that in the event that damages and/or settlement of the Amerada Hess Litigation results in an amount in excess of the $250,000 insurance coverage, that such excess will be paid as follows: (i) The Shareholders shall commence paying with the first dollar over the $250,000 and shall continue paying all dollars thereafter until such award and/or settlement amount reaches $1,250,000; and (ii) For all amounts awarded or for which settlement may be had in excess of $1,250,000 and commencing with the first dollar after $1,250,000, the Shareholders shall pay 20% of each dollar and TST shall pay 80% of each dollar. The Shareholders and Key agree that they will jointly, at TST's expense, pursue any third party, including Petrosurance Company, for reimbursement, collateral source money, or to enforce any other indemnity agreements. For monies recovered as a result of such pursuit, the Shareholders and TST shall divide each dollar recovered according to a ratio formula determined by a fraction whose numerator shall consist of the total amount of money paid by either the Shareholders or TST, and the denominator shall consist of the total monies paid by both the Shareholders and TST. Such fraction shall then be multiplied times the recovered amount of money to determine those sums reimbursable either to the Shareholders or TST. Key further agrees that upon the Closing, it shall cause TST to directly participate in the Amerada Hess Litigation and proceed with due diligence to reach resolution thereof by employing its own counsel to commence such legal activities as may be necessary to (i) apply pressure to TST's insurance carrier, AIG, to settle the Amerada Hess Litigation, and/or to tender the full policy amounts to assist in funding the settlement of said litigation, and (ii) initiate such activities as may be necessary to commence meaningful settlement discussions with Amerada Hess and other matters which management may deem prudent to rapidly conclude the Amerada Hess Litigation. The first $25,000 of the costs and expenses of such counsel shall be borne by TST with the remaining costs and expenses being shared equally by TST and the Shareholders. Key shall not consent to settle the Amerada Hess Litigation for an amount above $250,000 without the prior consent of the Shareholders, such consent not to be unreasonably withheld. ARTICLE 9 MISCELLANEOUS 9.1 Press Releases. Key, on the one hand, and the Shareholders, on the other, shall consult with each other before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby, and shall not issue any such press release or make any such public statement prior to receiving approval from the other party, such approval not to be unreasonably withheld or delayed. No announcement shall be made by any of the parties hereto prior to the Closing except as may specifically be required under the terms of this Agreement, except when in the opinion of the parties' counsel such public statement or announcement is legally required. 9.2 Survival of Representations, Warranties and Covenants.

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 for a period of 12 months from the Closing Date despite any investigation made by any party hereto or on its behalf. All covenants and agreements contained herein shall survive as provided herein. 9.3 Entirety. This Agreemennt 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. 9.4 Counterparts.
