     (a) Upon the execution and delivery of this Agreement by each of the parties hereto, Buyer shall pay to Seller $9,000,000 in cash, to be deposited by Seller into an interest bearing bank account (the “Transaction Account”) maintained by Seller with a commercial bank in the United States of America selected by Seller. Such amount, together with any earnings thereon while in such account shall be maintained in cash or cash equivalents and shall be referred to herein as the “Deposit.” The Deposit shall be maintained in the Transaction Account at all times prior to disbursement from such account to Buyer or retention of the Deposit by Seller in accordance with the provisions of this Agreement.

     (b) If the Closing occurs on or prior to December 31, 2006, then the Deposit shall be retained by Seller free of any restriction, and the Closing Cash Consideration shall be reduced by the amount of the Deposit.

     (c) If the Closing does not occur on or prior to December 31, 2006, and as of such date, all of the Deposit Forfeiture Conditions (as defined below) shall have been satisfied, then the Deposit shall be retained by Seller, as liquidated damages, and in such event, Seller, without any further act or consent by Buyer, shall be free to disburse the Deposit from the Transaction Account to one of Seller’s other accounts, this Agreement shall terminate (except that Section 1.4 and Section 9.7 and ARTICLE 11 shall survive such termination), and neither party shall have any further liability to the other party in connection with this Agreement or the transactions contemplated by this Agreement. The parties hereto acknowledge that the potential damages that would be incurred by Seller upon a failure by Buyer to consummate Buyer’s acquisition of the Transferred Assets by such date as contemplated by this Agreement, despite the satisfaction of the Deposit Forfeiture Conditions, are impossible to calculate, predict or estimate with any meaningful degree of accuracy, and further acknowledge and agree that such payment of the Deposit to Seller as liquidated damages is not intended, and shall not be construed, as a penalty and that such liquidated damages have been freely negotiated. As used herein, “Deposit Forfeiture Conditions” means, collectively, the following:

     (i) Seller shall have produced Adjusted EBITDA for the fiscal year ended October 31, 2006 of not less than $46,000,000. For purposes of this Agreement, “Adjusted EBITDA” shall be calculated as required pursuant to Section 5.13.

     (ii) Buyer shall have determined to its reasonable satisfaction based on information from the original manufacturers or a process mutually acceptable to Seller and Buyer that the sum of (i) the replacement cost (brand new) for those Transferred Assets constituting Seller’s rental equipment inventory and repair parts and supplies inventory and (ii) the fair market value based on current appraisals of the other Transferred Assets, is at least $200,000,000.

     (iii) The Federal Trade Commission and the Department of Justice shall have approved the transaction under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (the “HSR Act”), or any applicable waiting periods thereunder shall have expired or been terminated, in any case, without any requirement for any party to effect any divestiture.

     (iv) After the date of this Agreement, there shall not have occurred a Fundamental Adverse Change. For the purposes of this Agreement, “Fundamental Adverse Change” means the occurrence of (i) the cancellation of customer orders which orders are for amounts that in the aggregate would exceed 20% of Seller’s total revenue for the fiscal year ended October 31, 2006 or (ii) loss or damage (without the reasonable possibility of replacement or repair to brand new standards within 45 days of the occurrence of the loss or damage) of one or more items of Equipment that in the aggregate constitute at least 20% of the replacement cost (brand new) of all the Equipment.

     (v) The shareholders of Seller shall have approved the execution and delivery of this Agreement and all other Transaction Documents to which Seller is a party and the consummation of the transactions contemplated hereby and thereby.

     (vi) Seller shall not have terminated this Agreement pursuant to Section 10.1(a)(v).

     (vii) Buyer shall have received the title insurance commitments and other items mentioned in Section 5.7 hereof, in each case, relating to any of the Real Property constituting part of the Transferred Assets.

     (viii) The representations and warranties of Seller contained in Section 2.1, Section 2.2, Section 2.3, Section 2.5, Section 2.8(a) and Section 2.10 of this Agreement shall be true and correct in all material respects as though made on December 31, 2006.

     (ix) There shall have been no fraud committed by or on behalf of Seller in connection with the transactions contemplated by this Agreement.

     (d) If the Closing does not occur on or prior to December 31, 2006, and as of such date, any of the Deposit Forfeiture Conditions has not been fulfilled and satisfied, then Seller shall immediately return the Deposit to Buyer, this Agreement shall terminate (except that Section 1.4 and Section 9.7 and ARTICLE 11 shall survive), neither party shall have any further liability to the other party in connection with this Agreement and the transactions contemplated by this Agreement; provided, however, that if either of the Deposit Forfeiture Conditions set forth in Section 1.4(c)(ii), Section 1.4(c)(iii) or Section 1.4(c)(vii) has not been fulfilled or satisfied primarily as a result of action or inaction of Buyer, then the Deposit shall be retained by Seller in the Transaction Account until January 31, 2007 on which date (x) the Deposit shall be retained by Seller if all Deposit Forfeiture Conditions have been fulfilled or satisfied and the Closing has not occurred by January 31, 2007, (y) the Deposit shall be retained by Seller at the Closing and credited against the Closing Cash Consideration if all Deposit Forfeiture Conditions have been fulfilled or satisfied and the Closing occurs on or prior to January 31, 2007 or (z) the Deposit shall be retained by Seller if the Deposit Forfeiture Conditions have not been fulfilled or satisfied. Upon the occurrence of the events specified in clauses (x) or (z) of the immediately preceding sentence, this Agreement shall terminate (except that Section

1.4 and Section 9.7 and ARTICLE 11 shall survive) and neither party shall have any further liability to the other party in connection with this Agreement and the transactions contemplated by this Agreement. Furthermore, if the Closing does not occur on or prior to December 31, 2006, and as of such date, the Deposit Forfeiture Condition set forth in Section 1.4(c)(vi) has not been fulfilled and satisfied, then in addition to the return of the Deposit to Buyer in accordance with the first sentence of this Section 1.4(d), Seller shall immediately pay to Buyer an additional $1,000,000 in cash.

     Section 1.5 Allocation of Purchase Price and Working Capital Adjustment. As soon as practicable after the Adjustment Date (as defined in Section 1.6 below), the parties shall mutually agree to the allocation of the Purchase Price and the Working Capital Adjustment, if any, among the Transferred Assets on an asset-per-asset basis, in accordance with the rules of Section 1060 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury Regulations promulgated thereunder, and shall jointly prepare an IRS Form 8883 evidencing such allocation of the Purchase Price and the Working Capital Adjustment, if any. The parties shall use the amounts allocated pursuant to the preceding sentence for purposes of filing all tax returns, and shall not take any position inconsistent therewith on any tax return or for any other Tax (as defined in Section 2.11 below) purpose.

     Section 1.6 Working Capital Adjustment. In accordance with the provisions of this Section 1.6, and at the time therein set forth, Buyer shall pay to Seller or, as the case may be, Seller shall pay to Buyer, in immediately available funds, the amount of the Working Capital Adjustment (as defined below).

     (a) For the purposes of this Agreement, the term “Working Capital” shall mean, as of a particular date, the working capital of the Business, which working capital shall be computed in accordance with the methods, formulae, prorations and reserves set forth in Annex A attached hereto, and shall equal: (i) the aggregate amount of the current assets relating to the Business, which is comprised of (A) the Receivables (other than any Receivables that are more than 120 days old, unless and to the extent otherwise agreed by the parties hereto), net of reserves, (B) the amount of the Prepaids and (C) cash, cash equivalents, short-term investments and marketable securities; minus (ii) the aggregate amount of the current portion of the Assumed Liabilities. The amounts of all items to be used in the calculation of Working Capital will be based upon United States generally accepted accounting principles (“GAAP”), consistently applied. Notwithstanding anything to the contrary in this Agreement, the Deposit shall not constitute an asset or a liability for purposes of the calculation of Working Capital.

     (b) The Working Capital on the Closing Date shall be $11,300,000 (the “Target Working Capital”) and shall be included in the Transferred Assets.

     (c) Within forty-five (45) days after the Closing Date, Buyer shall deliver to Seller a statement of the Working Capital of the Business as of the Effective Time on the Closing Date (the “Statement of the Closing Date Working Capital” or “Statement”), which Statement shall (i) have been prepared by Buyer, after consultation with Seller, and reviewed by Buyer’s auditors, UHY LLP (or such other firm of independent certified public accountants appointed by Buyer for this purpose), in accordance with GAAP consistently applied, the provisions of Annex A and the provisions hereof, and (ii) set forth the Working Capital of the Business as of the Effective Time on the Closing Date (the “Closing Date Working Capital”). Following delivery by Buyer to Seller of the Statement of the Closing Date Working Capital, Buyer and its auditors shall permit Seller and its auditors at the earliest practicable date access to and copies of the work papers and calculations related thereto, and consult with Seller and its auditors as to any questions they may have.

     (d) Any dispute which may arise between Buyer and Seller as to the Closing Date Working Capital shall be resolved in the following manner:

     (i) If Seller disputes the calculation of the Closing Date Working Capital, or any portion thereof, Seller shall notify Buyer in writing within fifteen (15) days after its receipt of the Statement, and shall specify therein in reasonable detail the basis and reason for such dispute and the amount which is in dispute;

     (ii) During the fifteen (15) day period following the date of such notice from Seller, Buyer and Seller shall attempt to resolve such dispute; and

     (iii) If at the end of the fifteen (15) day period specified in clause (ii) above, the parties shall have failed to reach agreement with respect to such dispute, the matter shall be referred to the Houston, Texas office of such firm of independent certified public accountants as the parties mutually agree, who shall act as an arbitrator. The arbitrator shall be instructed to use every reasonable effort to perform such services within thirty (30) days of the submission to it of the Statement of the Closing Date Working Capital and the related dispute and, in any case, as soon as practicable after such submission. Each of the parties shall bear all costs and expenses incurred by it in connection with such arbitration, and the fees of the arbitrator shall be paid entirely by the party whose assertions regarding the Closing Date Working Capital differ by the greatest amount from the final Closing Date Working Capital determined by the arbitrator. This provision for arbitration shall be specifically enforceable by the parties and the decision of the arbitrator in accordance with the provisions hereof shall be final and binding and there shall be no right of appeal therefrom.

     (e) The latest to occur of (i) the date on which Seller accepts, or forfeits its right to contest, the Closing Date Working Capital disclosed in the Statement or (ii) the date on which the Closing Date Working Capital is determined in accordance with the provisions of Section 1.6(d) is referred to herein as the “Adjustment Date”.

     (f) Within ten (10) days after the Adjustment Date:

     (i) Buyer shall pay to Seller, in immediately available funds, an amount equal to the difference (if any, and if a positive result) between (A) the Closing Date Working Capital, minus (B) the Target Working Capital; or, alternatively

     (ii) Seller shall pay to Buyer, in immediately available funds, an amount equal to the difference (if any, and if a positive result) between (A) the Target Working Capital minus (B) the Closing Date Working Capital.

The amount, if any, payable as a result of the calculation in clauses (i) or (ii) above is referred to herein as the “Working Capital Adjustment.”

     Section 1.7 Assumed Liabilities. At the Closing, Seller shall transfer to Buyer, and Buyer shall assume, the Assumed Liabilities. For purposes of this Agreement, “Assumed Liabilities” shall mean only the following liabilities of Seller: (a) the accounts payable and accrued expenses arising from the conduct of the Business (“Payables”) in existence at the close of business on the Closing Date, (b) all obligations and liabilities with respect to the Transferred Employees attributable to the conduct of the Business from and after the Closing Date and (c) all obligations and liabilities of Seller with respect to the Transferred Assets, but only to the extent that such obligations (i) arise after the Closing Date, (ii) do not arise from or relate to any breach by Seller of any provision of such Assigned Contracts and (iii) do not arise from or relate to any event, circumstance or condition occurring or existing on or prior to the Closing Date, that, with notice or lapse of time or both, would constitute or result in a breach of such Assigned Contracts. OTHER THAN AS SET FORTH IN THE IMMEDIATELY PRECEDING SENTENCE, BUYER SHALL NOT ASSUME ANY OBLIGATION OR LIABILITY OF SELLER OR THE BUSINESS OF ANY KIND, AND SELLER SHALL PAY, SATISFY AND PERFORM ALL OF ITS REMAINING OBLIGATIONS, WHETHER FIXED, CONTINGENT, KNOWN OR UNKNOWN AND WHETHER EXISTING AS OF THE CLOSING OR ARISING PRIOR TO THE CLOSING, WHICH MAY AFFECT IN ANY WAY THE TRANSFERRED ASSETS.

     Section 1.8 Sales and Transfer Taxes. Except for vehicle transfer taxes, if any (which shall be the sole responsibility of Buyer), Seller shall be responsible for the payment of all stamp, documentary, registration, sales, use, excise, transfer, value added and similar Taxes (including any penalties and interest)

imposed by any Governmental Authority in any jurisdiction in connection with the sale of the Transferred Assets contemplated herein (collectively, the “Transfer Taxes”). Seller shall provide Buyer with an exemption certificate and any additional documents reasonably requested by Buyer to ensure that the transactions contemplated by this Agreement shall not be subject to any Transfer Taxes. The parties contemplate that the transfer of the Transferred Assets pursuant to this Agreement qualifies as an occasional sale and is generally exempt from sales tax under Texas Tax Code Sections 151.304(a) and 151.304(b)(2) and 34 Texas Administrative Code Section 3.316(d) and Louisiana Revised Statutes Section 47:301(1)(c).

Seller has the corporate power and authority to own, lease or operate all properties and assets now owned, leased or operated by it and to carry on its businesses as now conducted. For the purposes of this Agreement, “Material Adverse Effect” means any adverse change, circumstance or effect that, individually or in the aggregate with all other changes, circumstances or effects, is or would reasonably likely be materially adverse to the business, operations, assets, liabilities (including, without limitation, contingent liabilities) or condition (financial or otherwise), or results of operations of a person and it subsidiaries, taken as a whole; provided that, Material Adverse Effect shall not include any event, change in or effect upon financial condition, operating results or business of such person and its subsidiaries, directly or indirectly arising out of, attributable to or as a consequence of: (1) changes in law or any Governmental Authority’s policies or regulations or conditions, events or circumstances, in all such cases, generally affecting the oil and gas industry, relevant securities markets or the overall economy of the United States of America, (2) disruption resulting from transactions contemplated by this Agreement, including the public announcement thereof or (3) Reportable Conditions and recognized environmental conditions identified during a Phase I or Phase II assessment and any subsequent actions taken in response thereto.

This Agreement has been, and the other Transaction Documents to which Seller is a party will

be (on or prior to the Closing Date), duly and validly executed and delivered on behalf of Seller. Except as set forth in Schedule 2.3, neither the execution and delivery of this Agreement or the other Transaction Documents to which Seller is a party nor the consummation of the transactions contemplated herein or therein will result in a violation or breach of, or constitute a default under any term or provision of (a) the Certificate of Incorporation, Bylaws or other organizational documents of Seller or (b) (i) any indenture, note, mortgage, bond, security agreement, loan agreement, guaranty, pledge, or other instrument, contract, agreement or commitment, (ii) any law, statute, rule, regulation, Permit, ordinance, order, judgment, award, writ, injunction, consent judgment, consent order or decree or other pronouncement having the effect of law of any Governmental Authority (“Law”), (iii) any applicable ruling or order of any Governmental Authority, or (iv) any other commitment or restriction, in each case, to which Seller is a party or by which any of the Transferred Assets is subject or bound, nor will such actions result in the creation of any Lien on any of the Transferred Assets.

Except as set forth in Annex C, Seller will not have as of the date of the Fiscal 2006 Financial Statements, and Seller will not have incurred since that date, any Liabilities relating to the Transferred Assets or the Business, except Liabilities: (i) that, if required by GAAP to be accrued or reserved against, are accrued or adequately reserved against in the Fiscal 2006 Financial Statements; or (ii) that were incurred after the date of the Fiscal 2006 Financial Statements in the ordinary course of business of Seller and which could not reasonably be expected to have a Material Adverse Effect with respect to the Transferred Assets or the Business. For purposes hereof, “Liabilities” shall mean, with respect to the Transferred Assets or the Business, any debt, obligation or other liability related to the Transferred Assets or the Business, whether absolute, accrued, contingent, fixed or otherwise, or whether

Seller is not a party to, either as licensor or licensee, and is not bound by or subject to, any license agreement for any patent, process, trademark, service ▇▇▇▇, trade name or copyright, except as described in Schedule 2.16.

     Section 2.18 Securities Laws.

     (a) Seller is acquiring the Stock Consideration for its own account, without a view to the distribution thereof in violation of the Securities Act of 1933, as amended (the “Securities Act”). Seller does not have any contract, undertaking, agreement, understanding or arrangement with any person to sell, transfer or pledge to any Person any part or all of the Stock Consideration, or any interest therein, nor does Seller have any present plans to enter into the same. Seller agrees that it will not transfer any of the Stock Consideration except in compliance with applicable United States and other securities laws.

     (b) Seller is an “accredited investor” within the meaning of Regulation D under the Securities Act and was not organized solely for the purpose of acquiring any of the Stock Consideration. Seller has adequate means of providing for its current needs and contingencies, has no need now, and anticipates no need in the foreseeable future, to sell any portion of the Stock Consideration, and currently has sufficient net worth and financial liquidity to afford a complete loss of its investment in Buyer. Seller has such knowledge and experience in financial and business matters so that Seller is capable of evaluating the merits and risks of an investment in Buyer and has made such evaluation. Seller fully understands that the Stock Consideration is a speculative investment which involves a high degree of risk of loss of Seller’s entire investment. No person or entity, other than Buyer or its authorized representatives, has offered the Stock Consideration to Seller. Seller is able to bear the economic risk of an investment in the Stock Consideration.

     (c) Seller understands that Buyer has not registered the Stock Consideration under the Securities Act, and Seller agrees that the Stock Consideration may not be sold or transferred or offered for sale or transfer by it without registration under the Securities Act or the availability of an exemption therefrom. Seller has had an opportunity to ask questions of and receive answers from the management and authorized representatives of Buyer, and to review any other relevant documents and records concerning the business of Buyer, including all of Buyer’s current filings with the SEC, and the terms and conditions of this investment, and that any such questions have been answered to Seller’s full satisfaction. Seller understands that no Governmental Authority has passed upon or made any recommendation or endorsement of an investment in the Stock Consideration.

     Section 2.19 Full Disclosure. No representation or warranty of Seller contained in this ARTICLE 2 contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact necessary to make the statements contained herein or therein not misleading.

     Section 2.20 No Other Representations or Warranties. Except for the representations and warranties contained herein (including any annexes, exhibits, schedules or other attachments hereto and any certificates or other documents delivered in connection with the consummation of the transactions contemplated hereby), the Transferred Assets are being sold by Seller to Buyer “as is, where is” and Seller makes no express or implied representations or warranties with respect to the Transferred Assets, the Assumed Liabilities, the Business or any other matters, including without limitation the implied warranties of merchantability or of fitness for a particular purpose.

     (f) any claims, liabilities, obligations, damages, costs and expenses, known or unknown, fixed or contingent, claimed or demanded by third parties against any Seller Indemnitee arising out of or resulting from (i) the operation of the Business from and after the Closing, (ii) ownership or operation of the Transferred Assets and arising out of any fact or occurrence from and after the Closing or (iii) the Transferred Employees from and after the Closing.

     Section 7.3 Defense of Claims.

     (a) If any third-party claim or action arises after the Closing Date and during the Survival Period (as defined in Section 8.1 below) for which (i) Seller may be liable to any Buyer Indemnitee or (ii) Buyer may be liable to any Seller Indemnitee (for purposes of this ARTICLE 7, Buyer Indemnitees and Seller Indemnitees are sometimes referred to as “Indemnitee(s)” and, Seller and Buyer are sometimes referred to as “Indemnitor(s)”, in each case, as the context requires), such Indemnitee will, if a claim is to be made against an Indemnitor pursuant to this ARTICLE 7 or if the Indemnitee intends to take such claim into account in calculating the Threshold (as defined below), give prompt notice to the Indemnitor of the commencement of such claim, but the failure to notify the Indemnitor will not relieve the Indemnitor of any liabilities that the Indemnitor may have to the Indemnitee, except to the extent that the Indemnitor demonstrates that the defense of such action is prejudiced by the Indemnitees failure to give such notice. The expenses of all proceedings,

contests or lawsuits with respect to such claims or actions shall be borne by Indemnitor(s). If Indemnitor wishes to assume the defense of such claim or action, then Indemnitor shall give written notice to Indemnitees within twenty (20) days after notice from Indemnitees of such claim or action (unless the claim or action reasonably requires a response in less than twenty (20) days after the notice is given to Indemnitor, in which event Indemnitor shall notify Indemnitees at least five (5) days prior to such reasonably required response date), and Indemnitor shall thereafter assume the defense of any such claim or liability; provided that Indemnitees may participate in such defense at their own expense; provided further that in the event Indemnitees retain counsel as provided above, counsel retained by the Indemnitor shall be lead counsel.

     (b) If Indemnitor does not assume the defense of, or if after so assuming Indemnitor fails to defend, any such claim or action, then Indemnitees may defend against such claim or action in such manner as they may deem appropriate (provided that Indemnitor may participate in such defense at its own expense) and Indemnitees may settle such claim or litigation with the consent of Indemnitor (which shall not be unreasonably withheld or delayed so long as any such settlement is solely for money damages), and Indemnitor shall promptly reimburse Indemnitees for the amount of all expenses, legal and otherwise consented to by Indemnitor. If no settlement of such claim or litigation is made, Indemnitor shall satisfy any judgment rendered with respect to such claim or in such action, before Indemnitees are required to do so, and pay all expenses, legal or otherwise, reasonably and necessarily incurred by Indemnitees in the defense of such claim or litigation.

     (c) If a judgment is rendered against any of the Indemnitees in any action covered by the indemnification hereunder, or any lien in respect of such judgment attaches to any of the assets of any of the Indemnitees, Indemnitor shall immediately upon such entry or attachment pay such judgment in full or discharge such lien unless, at the expense and direction of Indemnitor, an appeal is taken under which the execution of the judgment or satisfaction of the lien is stayed. If and when a final judgment is rendered in any such action, Indemnitor shall promptly pay such judgment or discharge such lien before any of Indemnitees is compelled to do so.

     Section 7.4 Limits on Indemnification.

     (a) No party shall have any right to seek indemnification under this Agreement with respect to Losses contemplated by Section 7.1 or Section 7.2 that would otherwise be indemnifiable hereunder (including Losses incurred by all other Indemnitees affiliated with or related to such party) until such Losses exceed $3,350,000 in the aggregate (the “Threshold”); provided, however, that any Loss (or series of related Losses) contemplated by Section 7.1 or Section 7.2 must equal or exceed $50,000 to count towards the Threshold and to be indemnifiable pursuant to such sections, it being understood by the parties that once the Threshold has been exceeded then the Indemnitor shall be liable for all Losses in excess of $500,000 (other than any Loss or series of related Losses that is less than $50,000); provided, further, that the provisions of this Section 7.4(a) shall not apply to (i) any breach by Seller of the representations and warranties contained in Section 2.1, Section 2.2, Section 2.3, Section 2.5 and Section 2.8(a), (ii) any breach by Buyer of the representations and warranties contained in Section 3.1, Section 3.2, Section 3.3 and Section 3.4(b), (iii) the failure by any party to this Agreement to perform any unwaived covenant or agreement in this Agreement on its part to be performed or (iv) indemnification with respect to any and all Losses as contemplated by Section 7.1(c), Section 7.2(c) or Section 7.2(d).

     (b) Notwithstanding any provision of this Agreement, the aggregate liability of Seller under this ARTICLE 7 shall be limited to an amount equal to $35,000,000; provided, however, that the limitation set forth in this Section 7.4(b) shall not apply to (i) any breach by Seller of the representations, warranties and covenants contained in Section 2.1, Section 2.2, Section 2.3, Section 2.5 and Section 2.8(a), (ii) the failure by Seller to perform any unwaived covenant or agreement in this Agreement on its part to be performed or (iii) indemnification with respect to any and all Losses as contemplated by Section 7.1(c). Furthermore, subject to the preceding provisions of this Section 7.4(b), Seller’s indemnification obligations hereunder shall be satisfied solely out of the Stock Consideration and the cash and cash equivalents described in Section 9.10.

     (c) Notwithstanding any provision of this Agreement, the liability of Buyer under this ARTICLE 7 shall be limited to an amount equal to $35,000,000; provided, however, that the limitation set forth in this Section 7.4(c) shall not apply to (i) any breach by Buyer of the representations and warranties contained in Section 3.1, Section 3.2, Section 3.3 and Section 3.4(b), (ii) the failure by Buyer to perform any unwaived covenant or agreement in this Agreement on its part to be performed or (iii) indemnification with respect to any and all Losses as contemplated by Section 7.2(c) or Section 7.2(d).

     Section 7.5 Exclusive Remedies. After the Closing, the remedies provided by this ARTICLE 7 shall be the sole and exclusive remedy for the parties to this Agreement with respect to any dispute arising from, or related to, this Agreement except in the case of fraud and except that injunctive relief (including specific performance) shall continue to be available to the extent such remedy is in respect of a then surviving representation, warranty, covenant or agreement.

     Section 7.6 Allocation. Any payment of indemnifications by Seller pursuant to Section 7.1 shall be treated by the parties for tax purposes as an adjustment to the Purchase Price.

ARTICLE 8. SURVIVAL OF REPRESENTATIONS AND OTHER PROVISIONS.

     Section 8.1 Survival.

     (a) The representations, warranties, covenants, agreements and indemnities of the parties contained in this Agreement shall survive the consummation of the transactions contemplated herein and shall continue in full force and effect for the period (the “Survival Period”) beginning on the Closing Date and continuing for a period of eighteen (18) months (other than the representations and warranties set forth in Section 2.14, which shall terminate upon the Closing); provided, however, that obligations under Section 7.1(c), obligations under Section 7.2(c), obligations under Section 7.2(d) and the obligation to indemnify and hold harmless an indemnified party in respect of breaches of the representations and warranties in Section 2.11 (Taxes) and Section 2.12 (ERISA), shall, in each such case, survive the Closing Date until the expiration of the applicable statute of limitations period; and provided, further, that the Survival Period shall be extended automatically to include any time period necessary to resolve a specific claim for indemnification which was made before expiration of the Survival Period but not resolved prior to its expiration; and provided, further, that any such extension shall apply only as to claims asserted and not so resolved within the Survival Period.

     (b) The covenants and agreements made by the parties in this Agreement shall survive the Closing Date in accordance with their respective terms but, if Closing occurs, any covenant and agreement to be performed fully on or prior to the Closing Date shall be of no further force and effect after the Closing Date.

     (c) No party hereto (or its Affiliates) shall, under any circumstance, be liable to any other party (or its Affiliates) for any consequential, exemplary, special, incidental or punitive damages claimed by such other party under the terms of or due to any breach of this Agreement, including but not limited to, loss of revenue of income, cost of capital, or loss of business reputation or opportunity.

ARTICLE 9. ADDITIONAL AGREEMENTS.

     Section 9.1 Cooperation. The parties shall reasonably cooperate with each other in connection with any steps required to be taken as part of their respective obligations under this Agreement, and the parties shall use their commercially reasonable efforts to consummate the transactions contemplated herein and to fulfill their obligations hereunder, including without limitation causing to be fulfilled at the earliest practical date the conditions precedent to the obligations of the parties to consummate the transactions contemplated hereby. Without limiting the generality of the foregoing, Seller hereby covenants and agrees that, prior to the Closing, it will use its commercially reasonable efforts to cause the shareholders of Seller to authorize and approve the execution and delivery of this Agreement and the other Transaction Documents to which Seller is a party, the consummation of the transactions contemplated hereby and thereby and all other

action necessary to enable Seller to comply with the terms hereof and thereof. Without the prior written consent of the other party, no party hereto may take any intentional action that would cause the conditions precedent to the obligations of the parties hereto to effect the transactions contemplated hereby not to be fulfilled, including without limitation taking or causing to be taken any action which would cause the representations and warranties made by such party herein not to be true, correct and complete as of the Closing.

     Section 9.2 Access.

     (a) Following the date of this Agreement, for the purpose of permitting Buyer to conduct a due diligence review of the assets and business of Seller (including without limitation the Business), Seller will permit Buyer and its agents and representatives to have reasonable access during normal business hours to premises in which Seller conducts its business (including without limitation the Business) and to all of its assets, books, records, personnel, customers and suppliers and will furnish Buyer such financial data, operating data and other information as Buyer may reasonably request. Contact with customers and suppliers shall be coordinated between the parties and shall be done on a mutually agreeable basis. Assuming compliance with the requirements of this Section 9.2, Buyer will complete its due diligence by November 30, 2006.

     (b) Following the date of this Agreement, for the purpose of permitting Seller to conduct a due diligence review of the assets and business of Buyer, Buyer will permit Seller and its agents and representatives to have reasonable access during normal business hours to premises in which Buyer conducts its business and to all of its assets, books, records, personnel, customers and suppliers and will furnish Seller such financial data, operating data and other information as Seller may reasonably request. Seller will complete its due diligence by November 30, 2006.

     Section 9.3 Non-Compete.

     (a) Non-Compete. Seller shall not, for a period of two (2) years following the Closing Date, directly or indirectly, for itself or on behalf of or in conjunction with any Person:

     (i) engage, as an officer, partner, director, shareholder, owner, partner, joint venturer, member, manager, employee, contractor, lender or in a managerial or advisory capacity, or otherwise, nor shall it cause or permit any Affiliate, whether as an employee, independent contractor, consultant, advisor, or sales representative, or in any other capacity whatsoever, to engage in any business offering any services or products in competition with the Business, in the Territory serviced by Buyer or any of its Affiliates. For purposes hereof, the “Territory” shall mean the areas identified on Annex E;

     (ii) call upon or employ any Person who is, at that time, or has been, within two (2) years prior to that date, within the Territory, an employee or agent of Buyer or any of its Affiliates for the purpose or with the intent of enticing such employee away from or out of the employ of Buyer or any of its Affiliates, or

     (iii) call upon any Person who is, at that time, or has been, within two (2) years prior to that time, a customer or supplier of Buyer or any of its Affiliates within the Territory for the purpose of soliciting or selling services or products in competition with Buyer or any of its Affiliates within the Territory.

For purposes of this Agreement, the term “Affiliate” means, with respect to any Person, any Person directly or indirectly controlling, controlled by or under common control with, such Person; and “control” means the possession, directly or indirectly of the power to direct or cause the direction of management and policies of such Person, whether through the ownership of voting securities, by contract or otherwise.

     (b) Equitable Relief. Because of the difficulty of measuring economic losses as a result of a breach of the foregoing covenants, and because of the immediate and irreparable damage that could be caused for which Buyer would have no other adequate remedy, the parties agree that the foregoing covenant may be enforced by Buyer or its Affiliates by injunctions, restraining orders and other equitable actions in addition to any other relief to which Buyer may be entitled, without the necessity of posting a bond.

     (c) Reasonable Restraint. The parties hereto acknowledge and agree that the provisions contained in this Section 9.3 are ancillary or part of an otherwise enforceable agreement and contain limitations as to time and scope of activity to be restrained that are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other business interest of Buyer.

     (d) Material and Independent Covenant. Seller acknowledges that its agreement with the covenants set forth in this Section 9.3 are material conditions to Buyer’s agreement to execute and deliver this Agreement and to consummate the transactions contemplated hereby. All of the covenants in this Section 9.3 shall be construed as an agreement independent of any other provision in this Agreement or any other Transaction Document, and the existence of any claim or cause of action of Seller or any of its Affiliates, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement of such covenants. It is specifically agreed that the two (2) year period during which the agreements and covenants made in this Section 9.3 shall be computed by excluding from such computation any time during which Seller is in violation of any provision of this Section 9.3. The covenants contained in this Section 9.3 shall not be affected by any breach of any other provision hereof by any party hereto.

     Section 9.4 Transferred Employees; Severance.

     (a) Upon the Closing, Seller shall terminate all employees of the Business. Buyer shall invite all employees of the Business to apply for consideration for employment with Buyer upon Closing at terms and conditions of employment set by Buyer, in its sole discretion. Seller shall provide Buyer with all information reasonably requested by Buyer pertaining to such employees. Any such employees to whom Buyer offers employment and who elect to become employees of Buyer are hereinafter referred to collectively as “Transferred Employees” (and individually as a “Transferred Employee”) and all other employees are hereafter referred to as “Retained Employees”). Nothing in this Agreement shall be construed as giving any person any right to become an employee of Buyer or to any terms and conditions of employment, including without limitation any type or level of compensation or benefits, with Buyer. Nothing in this Agreement is intended to, nor does it confer any rights or privileges upon, any person not a party to this Agreement.

     (b) Seller shall be responsible for all pre-Closing obligations for Transferred Employees as of the Closing Date (except for those liabilities that are accrued on the Fiscal 2006 Financial Statements), and such pre-Closing obligations shall be vested and paid by Seller on the Closing Date. Seller shall be responsible for all liabilities and costs arising from or relating to any claims by or on behalf of persons who at or prior to the Closing are or were employees of Seller in the Business, in respect of severance pay, paid time off and accrued vacation for employees, accrued sick leave, personal days, shutdown benefits, and any other similar obligations or liabilities (the “Termination Costs”) relating to the termination of such employees’ employment with Seller, or any break in service or any other event entitling someone to payments for such benefits (a “Termination”), which occurs on or prior to the Closing.

     (c) Buyer shall be responsible for all Termination Costs accruing from and after the Closing Date relating to a Termination by Buyer which occurs after the Closing, in respect of any Transferred Employee.

     Section 9.5 Employee Benefits and Welfare Plans.

     (a) Buyer shall not assume any liabilities and obligations of Seller relating to employees or employee benefits. Without limiting the foregoing, Seller shall retain, and Buyer shall not assume, obligations and liabilities with respect to (i) any Plans or arrangements maintained, sponsored, contributed to, or required to be contributed to by Seller relating to Transferred Employees, Retained Employees or any other

present, former or retired employees of Seller, including without limitation liabilities and obligations for retiree benefits and (ii) except as provided in this Section 9.5, any other employee-related liabilities arising at or before, or by reason of, the Closing, or otherwise in respect of any period at or before the Closing.

     (b) Buyer shall provide or offer to provide “continuation coverage” (as defined in Section 4980B(f) of the Code) under Buyer’s group medical plan to Seller’s covered employees, including Retained Employees or former employees, and their qualified beneficiaries (as defined in Section 4980B(g) of the Code.

     (c) No assets or liabilities with respect to Transferred Employees shall be transferred, as a result of this Agreement, from any pension plans maintained, sponsored, contributed to, or required to be contributed to by Seller applicable to its employees to any plan maintained or established by Buyer, and Seller shall retain all assets related thereto and all obligations to fund or otherwise provide benefits accrued by Transferred Employees under such pension plans before the Closing.

     (d) Buyer shall provide credit for periods of service with Seller under Buyer’s plans, programs, and similar agreements, commitments or arrangements that provide benefits or compensation to or for the benefit of Buyer’s employees, including without limitation eligibility and vesting under any qualified employee benefit plan maintained by Buyer and credit under any seniority based benefit or compensation arrangement. Buyer shall further provide credit under Buyer’s group medical plan for any deductible or co-payment made by Seller’s employee’s prior to the Closing Date under Seller’s group medical plan.

     (e) Without limitation as to the provisions of Section 9.5(a) above, Seller will retain liability for all workers’ compensation liabilities of the Transferred Employees due to or based upon events occurring on or before the Closing, whether or not filed on or before the Closing. Buyer shall be liable for workers’ compensation liabilities of the Transferred Employees due to or based upon events occurring after the Closing.

     Section 9.6 Consents; Assignments; Additional Post-Closing Covenants. The parties will use their respective commercially reasonable efforts to obtain any consent, approval or amendment required to assign or transfer the Transferred Assets. With respect to the Required Consents, Seller shall use its commercially reasonable efforts to obtain the consents as soon as practicable after the Closing. Seller shall execute any such further documents or other instruments reasonably requested to complete the conveyance, or to fully vest in Buyer, good and marketable title to the Transferred Assets. In addition, from and after Closing, Seller agrees to promptly forward to Buyer all inquiries, notices, calls and other requests relating to the Business or the Transferred Assets.

     Section 9.7 Expenses. Buyer shall pay all costs and expenses incurred or to be incurred by it in negotiating and preparing this Agreement and carrying out the transactions contemplated hereby. Seller shall pay all costs and expenses incurred or to be incurred by it in negotiating and preparing this Agreement and carrying out the transactions contemplated hereby.

     Section 9.8 Exclusivity. Until the termination of this Agreement, (a) neither Seller nor its representatives or agents will solicit offers from, negotiate with or provide financial or operating information to, any third party for the purpose of determining any interest in acquiring Seller or any of its securities or material assets, (b) Seller and its representatives will cease any current discussions with any third parties concerning an acquisition transaction and shall negotiate exclusively with Buyer in connection therewith and (c) Seller will promptly notify Buyer in the event that it or any of its representatives receives any proposal concerning an acquisition of all or any part of Seller’s equity interests or all or any significant part of Seller’s assets, which notice shall include a copy of such proposal, if in writing or a summary of such proposal, if oral.

     Section 9.9 Public Disclosure. The parties shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the transactions contemplated by this Agreement, and shall not issue any such press release or

make any such public statement prior to such consultation and without the prior written consent of the other party, except as may be required by applicable Law or court process or by obligations pursuant to any listing agreement with any national securities exchange; provided, however, that any such required disclosure shall be in a form approved by each of Buyer and Seller (which such approval shall not be unreasonably withheld or delayed).

     Section 9.10 Lock-Ups. Seller hereby covenants and agrees that:

     (a) for a period commencing on the Closing Date and continuing through the date that is one (1) year after the Closing Date, Seller will not directly or indirectly sell, offer, contract or grant any option to sell (including without limitation any short sale), pledge, distribute (including without limitation by means of a stock dividend or other distribution to shareholders) or otherwise dispose of or transfer (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of) any shares of Common Stock constituting all or any portion of the Stock Consideration; and

     (b) for a period commencing on the Closing Date and continuing through the date that is eighteen (18) months after the Closing Date, Seller will maintain in the Transaction Account cash and cash equivalents in an aggregate amount not less than $10,000,000.

     Section 9.11 Delivery of Disclosure Items.

     (a) On or before the Disclosure Delivery Deadline, Seller shall deliver to Buyer true, correct and complete copies of:

     (i) each of the Schedules for which Seller is responsible referenced in this Agreement;

     (ii) each of the written Assigned Contracts;

     (iii) each of the Owned Real Property Title Documents;

     (iv) each of the Realty Use Rights; and

     (v) each of the Plans.

     (b) Seller shall use its commercially reasonable efforts to deliver to Buyer true, correct and complete copies of the Fiscal 2006 Financial Statements on or prior to November 27, 2006, and in any event as soon as practicable after the date hereof.

     (c) On or before the Disclosure Delivery Deadline, Buyer shall:

     (i) deliver to Seller true, correct and complete copies of each of the Schedules for which Buyer is responsible referenced in this Agreement; and

     (ii) apply for the Owner Policies of Title Insurance, as more fully described in Section 5.7.

     Section 9.12 Environmental Matters. The parties hereby acknowledge and agree that, on and after the date of this Agreement and prior to the Closing, Buyer may, at its election and expense, conduct one or more Phase I environmental assessments (each a “Phase I”) on any of the Real Property otherwise constituting part of the Transferred Assets (the “Subject Real Property”). In the event that any such Phase I shall identify any Reportable Conditions on any Subject Real Property, then Buyer may, at its election and expense, conduct one or more Phase II environmental assessments (each a “Phase II”) on such Subject Real Property. In the event that any such Phase II shall identify any Reportable Conditions on such Subject Real Property, then at Buyer’s election (and in its sole discretion), notwithstanding anything to the contrary set forth in this Agreement, either:

     (a) such Subject Real Property shall be deemed to be an Excluded Asset, and the Closing Cash Consideration shall be reduced by an amount equal to the fair market value of such Subject Real Property (provided that as used herein “fair market value” means the value that would be paid by a willing buyer to an unaffiliated willing seller in a transaction not involving distress or necessity of either party); or

     (b) after the Closing, Seller shall (at its expense and under its direction and control) use its commercially reasonable best efforts to diligently and promptly remediate all such Reportable Conditions in accordance with applicable Environmental Laws.

Notwithstanding anything to the contrary set forth in this Agreement, any and all expenses of Seller or other costs to Seller in connection with any remediation pursuant to clause (b) above (including any such expenses or costs arising from third party claims) shall not constitute “Losses” for which indemnification might otherwise be available to any Buyer Indemnitee pursuant to Section 7.1 of this Agreement or to any Seller Indemnitee pursuant to Section 7.2 of this Agreement. Accordingly, all such costs and expenses shall be disregarded for all purposes under Section 7.4 of this Agreement.

     Section 9.13 Post-Closing Title Insurance Matters. After the Closing, Seller shall use its commercially reasonable efforts to assist Buyer in obtaining the Owner Policies of Title Insurance, as more fully described in Section 5.7.

     Section 9.14 Post-Closing Auditor Matters. If the Closing occurs, then for so long as Buyer would be required under the rules and regulations of the SEC (including without limitation Regulation S-X), to include any financial statements of Seller (or financial statements relating to the Transferred Assets) in a registration statement of Buyer filed under the Securities Act, (a) Seller, at Buyer’s sole cost and expense, shall allow Buyer to include the financial statements of Seller for the three year period ended October 31, 2006 in any filing by Buyer with the SEC and/or in any offering memorandum or circular prepared by Buyer in connection with a securities offering conducted pursuant to Rule 144A under the Securities Act and (b) Seller, at Buyer’s request, will request its auditors to provide to Buyer access to all work papers and accounting records in its possession relating to Seller in connection with such SEC filings or securities offerings, and Buyer shall pay all costs and expenses of such auditors in connection with such matters.

     Section 9.15 Post-Closing Accounting Matters. If the Closing occurs, then for a period of three (3) months after the Closing Date, Buyer will use its commercially reasonable efforts to cooperate with Seller such that Seller can obtain copies of its accounting records from the computer equipment, hardware and software transferred to Buyer as part of the Transferred Assets.

     Section 9.16 Tax Cooperation. Buyer and Seller shall reasonably cooperate in good faith to minimize, to the fullest extent possible under provisions of all applicable laws, the amount of any taxes payable in connection with the transfer of the Transferred Assets pursuant to this Agreement with the understanding that such cooperation shall not affect the Parties’ respective responsibilities for reporting, remitting and paying taxes or their obligations set forth in Section 1.8.

     (i) by mutual written consent of Buyer and Seller;

     (ii) by Seller, if (i) there has been a breach by Buyer of any representation, warranty, covenant or agreement set forth in this Agreement or if any representation or warranty of Buyer shall have become untrue, in either case such that the conditions set forth in ARTICLE 6 would not be

satisfied and (ii) such breach is not curable, or, if curable, is not cured within 30 days after written notice of such breach is given by Seller to Buyer; provided, however, that the right to terminate this Agreement pursuant to this section shall not be available to Seller if Seller, at such time, is in material breach of any representation, warranty, covenant or agreement set forth in this Agreement such that the conditions set forth in ARTICLE 5 shall not be satisfied;

     (iii) by Buyer, if (i) there has been a breach by Seller of any representation, warranty, covenant or agreement set forth in this Agreement or if any representation or warranty of Seller shall have become untrue, in either case such that the conditions set forth in ARTICLE 5 would not be satisfied and (ii) such breach is not curable, or, if curable, is not cured within 30 days after written notice of such breach is given by Buyer to Seller; provided, however, that the right to terminate this Agreement pursuant to this section shall not be available to Buyer if Buyer, at such time, is in material breach of any representation, warranty, covenant or agreement set forth in this Agreement such that the conditions set forth in ARTICLE 6 shall not be satisfied;

Noncompetition, Nondisclosure, and Nonsolicitation Agreement

     This Noncompetition, Nondisclosure, and Nonsolicitation Agreement (“Agreement”) is made and entered effective as of _____ ___, 2006, by and between [Insert one of the following: ▇▇▇▇▇-▇▇▇▇▇▇▇▇ Energy Inc., a Delaware corporation / ▇▇▇▇▇-▇▇▇▇▇▇▇▇ Rental Tools, Inc., a Texas corporation] (“Company”) and                                         , an individual (“Employee”).

     The Company and Employee desire to enter into an agreement (i) defining the relative rights of the Company and Employee with respect to Trade Secrets and Confidential Information (as defined below) which Employee receives and to which Employee has access as a result of Employee’s employment with the Company, (ii) setting forth Employee’s obligation to refrain from competing with the Company during Employee’s employment with the Company and for a reasonable period of time thereafter as provided herein, and (iii) setting forth Employee’s obligation not to solicit or recruit the Company’s employees for employment elsewhere and not to solicit customers of the Company for a reasonable period of time as provided herein. Employee’s acknowledgments, agreements, promises, and representations in the Agreement inure to the benefit of not only the Company, but also of its subsidiaries, affiliates, successors, and assigns. In consideration of the promises and mutual covenants herein contained, the parties agree as follows:

1.

Trade Secrets/Confidential Information. Employee acknowledges that during the course of Employee’s employment, Employee will be provided, be exposed to, have access to, and gain knowledge of Trade Secrets and Confidential Information of the Company and/or its subsidiaries and affiliates. “Trade Secrets” means all information and compilations of information of any kind, type, or nature (tangible and intangible, written or oral, and including information contained, stored, or transmitted through any electronic medium). Trade Secrets consist of, but are not limited to, computer software, specifications and code, customer lists, confidential customer information, source code, executable code, pricing data, sources of supply, products or services, fees, costs and pricing structures, designs, analysis, drawings, technology, manuals and documentation, databases, accounting and business methods and plans, inventions, devices, new ideas and developments, methods and processes, sales information, marketing information, production procedures, merchandising systems or plans of the Company and/or its subsidiaries or affiliates, the Company’s and/or its subsidiaries’ and affiliates’ customers, and inventions made, developed or conceived by the Company and/or its subsidiaries and affiliates. “Confidential Information” means all information and compilations of information of any kind, type or nature (tangible and intangible, written or oral, and including information contained, stored, or transmitted through any electronic medium), whether owned by the Company or licensed from third parties, which, at any time during the employment of Employee, is devised, developed, designed or discovered or otherwise acquired or learned by Employee to the extent it relates to the Company or its subsidiaries, affiliates, partners, business, services, products, processes, properties or assets, customers, good-will, customers, markets, source code, executable code, marketing strategies, product plans, formulae, management, employees, technology and technical data, research, know-how, trade secrets, financial conditions or prospects, including, but not limited to, employee compensation, customers, customer lists,

customer fee information, business development plans and strategies, marketing plans and strategies, fees, costs, pricing structures and inventions. Employee acknowledges and agrees that the Trade Secrets and Confidential Information are valuable and unique assets that provide the Company an advantage over competitors, are developed or acquired by the Company and/or its subsidiaries and affiliates at considerable time and expense, and are proprietary to the Company and are intended to be used solely for the benefit of the Company and/or its subsidiaries and affiliates. Employee acknowledges and agrees that, but for the Employee’s agreement to the terms and conditions of this Agreement, the Company and/or its subsidiaries and affiliates would not impart or provide access to such Trade Secrets and Confidential Information.

2.		Nondisclosure. Employee acknowledges and agrees that the Company and/or its subsidiaries and affiliates have put in place certain policies and practices to safeguard such Trade Secrets and Confidential Information, including requiring employees, customers and vendors to execute confidentiality agreements. Employee further acknowledges and agrees that such Trade Secrets and Confidential Information are valuable and unique assets that provide the Company and/or its subsidiaries and affiliates an advantage over competitors who do not know such Trade Secrets and Confidential Information. Employee also acknowledges and agrees that such Trade Secrets and Confidential Information are developed or acquired by the Company at considerable time and expense and are intended to be used solely for the benefit of the Company and/or its subsidiaries and affiliates. Accordingly, Employee agrees that both during the term of Employee’s employment with the Company and during the Non-Compete Period, Employee will (i) hold all information of any kind, nature or description relating to the Company’s and its subsidiaries’ and affiliates’ Trade Secrets and Confidential Information in strict confidence and will not disclose, make available, discuss, transmit, lecture upon, publish or use such Trade Secrets and Confidential Information other than for the Company’s benefit, and (ii) not disclose (directly or indirectly), use, cause, facilitate or allow any third party to use Confidential Information or Trade Secrets in any way, except as authorized by the Company’s Chief Executive Officer, or someone designated by the Company’s Chief Executive Officer, in writing or as required by law. Employee further acknowledges and agrees that the Company’s conduct in providing Employee with Trade Secrets and Confidential Information in exchange for Employee’s nondisclosure agreement gives rise to the Company’s interest in restraining Employee from competing against the Company as set forth in Sections 6 and 8, and that Employee’s agreement to those provisions is designed to enforce Employee’s nondisclosure agreement.
3.		Former Employer and Third Party Information. Employee agrees that Employee will not, at any time during Employee’s employment with the Company, improperly use or disclose any Confidential Information or Trade Secrets of any former or concurrent employer or other person or entity and that Employee will not bring into the Company any unpublished document or confidential information belonging to any such other employer, person or entity unless consented to in writing by such employer, person or entity. Employee agrees that the Company has received and in the future will receive from third parties certain trade secret and confidential information, subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes within the course and scope of the Company’s relationship with such third parties and of Employee’s

employment with the Company. Employee agrees to hold all such third party confidential information in the strictest of confidence, not to disclose it to any person, firm, or corporation or to use it except as necessary in carrying out Employee’s work for the Company consistent with the Company’s agreement with such third party, and to use the same standard of care in safeguarding such confidential information as Employee is required to use in safeguarding the Company’s Trade Secrets and Confidential Information.

4.		Return of Company Property. Upon termination of employment, Employee agrees to return to the Company (and will not keep in Employee’s possession, recreate, or deliver to any one else) all property and documents of and/or relating to the Company, and its customers and clients, including but not limited to the following: Confidential Information, Trade Secrets, all disks and copies of software applications utilized by the Company or the Company’s clients, customers, or business, hard and soft copies of data, drawings, notes, proposals, specifications, blueprints, sketches, equipment, records, reports, analyses, manuals, correspondence, customer lists, computer programs, intellectual property, and all other materials or property and all copies or reproductions thereof relating in any way to the Company’s business, or in any way obtained or developed by Employee during Employee’s employment with the Company. Employee also agrees not to retain any copies of the foregoing.
5.		Inventions. Employee acknowledges and agrees that all works or authorship and/or inventions of any kind (including, without limitation, processes and methodologies) which are made by Employee (solely or jointly with others) within the scope of and during the period of Employee’s employment with the Company (collectively “Work”) shall be owned solely by the Company, unless Employee identifies such Works as Independent Inventions (as defined in Exhibit B). As such, Employee agrees to all the terms set forth in Exhibits B & C which relate to Works.
6.		Noncompetition Agreement.

     (a) Employee acknowledges and agrees that Employee’s training, work, and experience with the Company enhances Employee’s value to competitors, and that the nature of the Confidential Information and Trade Secrets to which Employee has access makes it difficult, if not impossible for Employee to work for any person or entity carrying on or engaging in a business similar to that of the Company without disclosing or utilizing the Trade Secrets and Confidential Information to which Employee has access during the course of Employee’s employment. Employee further acknowledges and agrees that the Company’s agreement to impart to and to provide Employee with access to its Trade Secrets and Confidential Information is ancillary to and contingent upon Employee’s agreement that Employee will not, for a period of two (2) years immediately following the Employee’s last day of employment with the Company or two (2) years from the date of any court order enforcing all or part of this Agreement, whichever is later (the “Non-Compete Period”), do any of the following:

     (i) carry on, engage, or have any ownership or equity interest (directly or indirectly) in a business similar to that of the Company or its subsidiaries, affiliates, successors or assigns or that otherwise competes with the Company within the areas

identified in Exhibit A, provided that this Section 6(a)(i) shall not apply to the ownership by Employee of less than 5% of a class of publicly traded equity securities;

     (ii) become employed by, derive benefit from or otherwise provide services for compensation or divert the Company’s business to any person or entity carrying on or engaging in a business similar to that of the Company or its subsidiaries, affiliates, successors or assigns or that otherwise competes with the Company within the areas identified in Exhibit A; or

     (iii) contact, solicit, or divert (directly or indirectly) any customer with whom the Company has had a contractual relationship during the two year (2) period prior to Employee’s last day of employment with the Company for the purpose of attempting to enter into a business relationship related to the rental, sale, manufacture, distribution, or servicing of products or services rented, sold, manufactured, distributed, or serviced by the Company or its subsidiaries, affiliates, successors or assigns.

     (b) The Company’s business, both actual and intended, includes, without limitation, providing oil and gas rental equipment for onshore and offshore well drilling, completion, and workover operations, including without limitation, premium drill pipe, heavy weight spiral drill pipe, tubing work strings, blow out preventors, choke manifolds, and various valves and handling tools. Employee acknowledges that this description of the business, both actual and intended, is not intended to be limiting and that the business will continue to grow and evolve and the range of services and the ways of providing services will continue to be enhanced and supplemented.

     (c) Employee understands and agrees that the scope of each of the agreements and promises contained in this Section 6 is reasonable as to time, area, and scope of activity restrained and is necessary to protect the Company’s legitimate business interests. Specifically, Employee has considered the agreements and promises in light of the benefits that Employee will obtain by means of this Agreement and has concluded that the promises and agreements leave Employee with a reasonable number and variety of permitted avenues for engaging in employment in a number of locations and a number of occupations during the period of restriction.

7.

Performance. Employee acknowledges and agrees that Employee’s position with the Company is a position of trust and confidence. Employee shall devote Employee’s full time to the performance of Employee’s responsibilities faithfully, industriously, and to the best of Employee’s abilities, and will not take any action at any time while employed by the Company, which would conflict or jeopardize in any way the Company’s interests or objectives.

General Provisions.

     (a) Not an Employment Agreement. Employee and the Company acknowledge and agree that this Agreement is not intended and should not be construed to grant Employee any right to continued employment with the Company. Therefore, nothing in this Agreement or the execution of this Agreement shall in any way be deemed to establish an employment relationship on a basis other than terminable at will.

     (b) Absence of Conflicting Agreements. Employee hereby warrants and covenants that Employee’s employment by the Company and Employee’s execution, delivery and performance of this Agreement do not and will not result in a breach of the terms, conditions or provisions of any agreement, order, judgment or decree to which Employee is subject.

     (c) Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable if any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. The parties agree that a court of competent jurisdiction making a determination of the invalidity or unenforceability of any term or provision of this Agreement will have the power to reduce the scope, duration or area of any such term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement will be enforceable as so modified.

     (d) Complete Agreement. This Agreement, those documents expressly referred to herein and other documents of even date herewith embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

     (e) Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed to be an original and all of which taken together constitute one and the same agreement.

     (f) Subsidiaries, Affiliates, Successors, and Assigns. Except as otherwise provided herein, this Agreement will inure to the benefit of and be enforceable by the Company, its subsidiaries, affiliates, successors and assigns, and may be assigned by them. The rights and obligations of Employee under this Agreement will not be assignable by Employee without the prior written consent of the Company.

     (g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS. THE TRADE SECRETS AND CONFIDENTIAL INFORMATION PROTECTED BY THIS AGREEMENT SHALL BE SUBJECT TO PROTECTION AND SEAL TO THE FULL EXTENT CONTEMPLATED BY THE LAWS OF THE STATE OF TEXAS.

WITH RESPECT TO ANY SUIT, ACTION, OR OTHER PROCEEDING ARISING FROM (OR RELATING TO) THIS AGREEMENT, THE COMPANY AND EXECUTIVE HEREBY IRREVOCABLY AGREE TO THE EXCLUSIVE PERSONAL JURISDICTION AND VENUE OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF TEXAS (AND ANY TEXAS STATE COURT WITHIN ▇▇▇▇▇▇ COUNTY, TEXAS).

     (i) Reaffirmation. Immediately at the time Employee’s employment with the Company ends, Employee will ratify Sections 11(g) and 11(h) of this Agreement.

     (j) Remedies. Employee acknowledges and agrees that any breach or violation of any term or provision of this Agreement will result in immediate and irreparable harm to the Company and will cause damage to the Company in amounts difficult to ascertain. Accordingly, in the event of a breach or threatened breach by Employee of this Agreement, the Employee agrees that the Company, in addition to and without limitation of any other rights, remedies or damages available to the Company, at law or in equity, shall be entitled, without posting bond or proving actual damages, to a temporary restraining order and to a preliminary and/or permanent injunction in order to prevent or restrain any such breach by the Employee or the Employee’s partners, agents, representatives, employers, employees, and/or any and all persons directly or indirectly acting for or with or for the benefit of Employee. The parties acknowledge that the remedies contained in this Section are reasonably related to the injuries the Company may sustain as a result of the Employee’s breach of Employee’s obligations under the Agreement and are not a penalty. No delay or omission by the Company in exercising any right under this Agreement will operate as a waiver of that or any other right. The foregoing shall not otherwise limit the Company’s rights and remedies hereunder. A waiver or consent given by the Company on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other occasion. The validity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement.

     (k) Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written consent of the Company and Employee.

     EMPLOYEE acknowledges that Employee has carefully read this Agreement and understands and agrees to all of the provisions in this Agreement.

INVENTIONS

a.		Inventions Retained and Licensed. To preclude any possible uncertainty over the ownership of any invention, I have attached hereto, as Exhibit C, a complete list of all inventions, original works of authorship, developments, improvements, and trade secrets which (i) were made by me, either alone or jointly with others, prior to commencement of my employment with the Company, independently and not as a part of or relation to the work I have or will perform for the Company; (ii) belong to me only; (iii) relate to or could relate to the Company’s proposed business, products or research and development; and (iv) I do not intend to assign to the Company hereunder (collectively referred to as “Independent Inventions”); or, if no such list is attached, I represent that there are no such Independent Inventions. If disclosure of any such invention on Exhibit C would cause me to violate any prior confidentiality agreement, I understand that I am not to list such inventions in Exhibit C but am to inform the Company that all inventions have not been listed for that reason. If in the course of my employment with the Company, I incorporate into any invention, improvement, development, product, copyrightable material or trade secret any invention, improvement, development, concept, discovery or other proprietary information owned by me or in which I have an interest, the Company is hereby granted and shall have a nonexclusive, assignable, royalty-free, irrevocable, perpetual, sublicenseable (through one or multiple tiers), worldwide license to make, have made, modify, reproduce, distribute, create derivative works of, use, offer to sell, and sell such item as part of or in connection with such product, process or machine.
b.		Assignment of Inventions. I agree that I (i) will promptly make full written disclosure to the Company, (ii) will hold in trust for the sole right and benefit of the Company, and (iii) hereby assign to the Company, or its designee, all my right, title, and interest in and to any and all inventions, original works of authorship, developments, concepts, improvements or trade secrets, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the period of time during which I perform work for the Company (collectively referred to as “Company Inventions”). I further acknowledge that all original works of authorship which are made by me (solely or jointly with others) within the scope of and during the period in which I perform work for the Company and which can be protected by copyright are “works made for hire,” as that term is defined in the United States Copyright Act, and shall be the sole and complete property of the Company. To the extent that any such work of authorship may not be deemed a work made for hire, I hereby irrevocably assign all my ownership rights in and to such work in the Company. If any such work cannot be assigned, I hereby grant to the Company an exclusive, assignable, irrevocable, perpetual, worldwide, sublicenseable (through one or multiple tiers), royalty-free, unlimited license to make, have made, modify, use, reproduce, distribute, create derivative works of, display, offer to sell, and sell such work in any media now known, or hereafter known. Outside the scope of my employment, I agree not to (i) modify, adapt, alter, translate, or create derivative works from any such work of authorship, or (ii) merge any such work of authorship with other inventions.

Exhibit B - 1

c.		Inventions Assigned to the United States. I agree to assign to the United States government all my right, title, and interest in and to any and all Company Inventions whenever such full title is required to be in the United States by a contract between the Company and the United States or any of its agencies.
d.		Maintenance of Records. I agree to keep and maintain adequate and current written records of all Company Inventions made by me (solely or jointly with others) during the period in which I perform work for the Company. The records will be in the form of notes, sketches, drawings, and any other format that may be specified by the Company. The records will be available to and remain the sole property of the Company at all times.
e.		Patent and Copyright Registrations. I agree to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Company Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns and nominees, the sole and exclusive rights, title and interest in and to such Company Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after the termination of this Agreement. If the Company is unable because of my mental or physical incapacity or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Company Inventions or original works of authorship assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by me. I hereby waive and quitclaim to the Company any and all claims, of any nature whatsoever, that I now or may hereafter have for infringement of any ownership rights assigned hereunder to the Company.
f.		Obligation to Keep the Company Informed. During the first year after termination of my employment, I will provide the Company with a complete copy of each patent application and copyright registration application (including any mask work registration application) filed by me or that names me as an inventor, co-inventor, author, co-author, creator, co-creator, developer, or co-developer.
g.		No Reciprocal License. I acknowledge and agree that nothing in this Agreement shall be deemed to grant, by implication, estoppel, or otherwise, (i) a license from the Company to me to make, use, license, or transfer in any way a Company Invention; or (ii) a license from the Company to me regarding any of the Company’s existing or future ownership rights.

Accordingly, if a court of competent jurisdiction determines that the scope and/or operation of any provision of this Agreement is too broad to be enforced as written, the Company and Executive intend that the court should reform such provision to such narrower scope and/or operation as it determines to be enforceable. If, however, any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future law, and not subject to reformation, then (i) such provision shall be fully severable, (ii) this Agreement shall be construed and enforced as if such provision was never a part of this Agreement, and (iii) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by illegal, invalid, or unenforceable provisions or by their severance.

          5.11 General Creditor Status. All cash payments to which Executive may become entitled hereunder will be paid, when due, from the general assets of the Company, and no trust fund, escrow arrangement or other segregated account will be established as a funding vehicle for such payment. Accordingly, Executive’s right (or the right of the personal representatives or beneficiaries of Executive’s estate) to receive such cash payments hereunder will at all times be that of a general creditor of the Company and will have no priority over the claims of other general creditors.

          5.12 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

          5.13 Jurisdiction. WITH RESPECT TO ANY SUIT, ACTION, OR OTHER PROCEEDING ARISING FROM (OR RELATING TO) THIS AGREEMENT, THE COMPANY AND EXECUTIVE HEREBY IRREVOCABLY AGREE TO THE EXCLUSIVE PERSONAL JURISDICTION AND VENUE OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF TEXAS (AND ANY TEXAS STATE COURT WITHIN ▇▇▇▇▇▇ COUNTY, TEXAS).

          5.14 Reaffirmation. Immediately at the time Executive’s employment with the Company ends, Executive will ratify Sections 5.12 and 5.13 of this Agreement.

          5.15 Counterparts. This Agreement may be executed in any number of counterparts and by facsimile, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

whether such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration; provided, however, that a Transfer to a Permitted Assignee will not be subject to this Section 3 as long as (x) such Transfer is effected in accordance with applicable securities laws; (y) such transferee agrees in writing to become subject to the terms of this Agreement as a Holder; and (z) the Company is given written notice by such Holder of such Transfer, stating the name and address of the transferee and identifying the Shares being Transferred.

     (b) Furthermore, each Holder hereby authorizes the Company during the Market Standoff Period to cause any transfer agent for the Relevant Securities to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, any Relevant Securities for which such Holder is the record holder and, in the case of Relevant Securities for which such Holder is the Beneficial Owner but not the record holder, agrees during the Market Standoff Period to cause the record holder thereof to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Relevant Securities.

     (c) Subject to the provisions of Section 4(b), without the prior written consent of the Company, during the Market Standoff Period such Holder (x) will not participate in the filing with the SEC of any registration statement, or circulate or participate in the circulation of any preliminary or final prospectus or other disclosure document with respect to any proposed offering or sale of a Relevant Security and (y) will not exercise any rights the undersigned may have to require registration with the SEC of any proposed offering or sale of a Relevant Security (including without limitation pursuant to this Agreement).

     Section 4. Registration Rights.

     (a) Shelf Registration Statement. The Company shall (i) file with the SEC a shelf registration statement on Form S-1 (or, if the Company is eligible to use such form, Form S-3) relating to the registration of the offer and resale by the Holders of all of the Registrable Securities (the “Shelf Registration Statement”) and (ii) use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective by the SEC no later than the date that is one (1) year after the Closing Date; provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 4(a), or keep such registration or the Shelf Registration Statement effective pursuant to Section 4(c)(i), during any Blackout Period.

     (b) Piggyback Registration Rights.

     (i) Piggyback Registration. If after the date that is one (1) year after the Closing Date, the Company shall determine to register the offer and sale for cash of any of its Common Stock for its own account, other than (i) a registration relating solely to employee benefit plans or securities issued or issuable to employees, consultants (to the extent the securities owned or to be owned by such consultants could be registered on Form S-8) or any of their Family Members (including a registration on Form S-8), (ii) a registration on Form S-4 in connection with a merger, acquisition, divestiture, reorganization, exchange offer or similar event, or (iii) a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt

securities that are also being registered, then (subject to Section 4(b)(iii)) the Company shall promptly give to the Holders written notice thereof, and in no event shall such notice be given less than 20 calendar days prior to the filing of a registration statement (each a “Piggyback Registration Statement” and collectively the “Piggyback Registration Statements”) with respect to such registration (each a “Piggyback Registration”), and shall, subject to Section 4(b)(ii) and Section 4(b)(iii), include in such Piggyback Registration, all of the Registrable Securities specified in a written request or requests, made within 10 calendar days after receipt of such written notice from the Company, by any Holder or Holders. However, the Company may, without the consent of the Holders, withdraw such Piggyback Registration Statement prior to its becoming effective if the Company has elected to abandon the proposal to register the securities proposed to be registered thereby.

     (ii) Underwriting. If a Piggyback Registration is for a registered public offering involving an underwriting, the Company shall so advise the Holders in writing or as a part of the written notice given pursuant to Section 4(b)(i). In such event the right of any Holder to registration pursuant to Section 4(b)(i) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Section 4(b)(ii), if the underwriter or the Company determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise all Holders (except those Holders who failed to timely elect to distribute their Registrable Securities through such underwriting or have indicated to the Company their decision not to do so), and the number of shares that may be included in the registration and underwriting shall be allocated:

     (A) first to the Company; and

     (B) then, subject to written obligations and commitments existing as of October 25, 2006, to all selling stockholders, including the Holders, who have requested to sell in the registration on a pro rata basis according to the number of shares requested to be included.

No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter. The Registrable Securities and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities pursuant to the terms and

limitations set forth herein in the same proportion used above in determining the underwriter limitation.

     (iii) Notwithstanding anything to the contrary set forth in this Agreement, the Company shall not be obligated to effect, or take any action to effect, any registration pursuant to Section 4(b) after the Company has initiated two (2) such registrations (counting for this purpose only registrations which have been declared or ordered effective and pursuant to which securities have been sold).

     (c) Registration Procedures. In the case of each registration, qualification, or compliance effected by the Company pursuant to Section 4(a) and Section 4(b), the Company will keep each Holder including securities therein reasonably advised in writing (which may include e-mail) as to the initiation of each registration, qualification, and compliance and as to the completion thereof. In addition, the Company hereby agrees as follows with respect to each Registration Statement:

     (i) The Company will use its commercially reasonable efforts to cause such Registration Statement to become and remain effective at least for a period ending with the first to occur of (A) the sale by the Holders of all Registrable Securities covered by such Registration Statement, (B) the availability under Rule 144 for the Holders to immediately, freely resell without restriction under United States federal securities laws all Registrable Securities covered by such Registration Statement, or (C) the date that is two years after the SEC Effective Date of such Registration Statement (provided, however, that if the Company files a Registration Statement on Form S-1 and subsequently becomes eligible to use Form S-3, it may file a post-effective amendment to such Form S-1 on Form S-3 prior to the end of such period and use its commercially reasonable efforts to cause such Registration Statement as amended to become effective until the end of such period) (in any such case, the “Effectiveness Period”). At any time after the end of the Effectiveness Period with respect to the Shelf Registration Statement, if (a) the Holders Beneficially Own Registrable Securities representing more than 10% of the fully diluted equity interests in the Company (calculated giving effect to the exercise of all outstanding options, warrants and other rights to purchase to acquire any Common Stock of the Company) or (b) any nominee designated by the Holders pursuant to Section 2(a) is a member of the Board, then (x) as promptly as reasonably practicable after the written request of Holders of a majority of the Registrable Securities, the Company shall file with the SEC another shelf registration statement on Form S-1 (or, if the Company is eligible to use such form, Form S-3) relating to the registration of the offer and resale by the Holders of all of the Registrable Securities, (y) the provisions of this Agreement (including without limitation the provisions of Section 4(a) and Section 4(c)) shall apply to such registration statement and (z) such registration statement shall be deemed to be the Shelf Registration Statement (as defined in Section 4(a)) for purposes of this Agreement.

     (ii) If any Registration Statement becomes subject to review by the SEC, the Company will promptly respond to all comments and diligently pursue resolution of any comments to the satisfaction of the SEC.

     (iii) The Company will prepare and file with the SEC such amendments and supplements to each Registration Statement and any prospectus used in connection therewith as may be reasonably necessary to keep such Registration Statement effective during the applicable Effectiveness Period, and will comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended method(s) of disposition by the sellers thereof set forth in such Registration Statement.

     (iv) The Company will furnish, without charge, to each Holder (A) a reasonable number of copies of each Registration Statement (including any exhibits thereto other than exhibits incorporated by reference), each amendment and supplement thereto as such Holder may request, (B) such number of copies of the prospectus included in such Registration Statement (including each preliminary prospectus and any other prospectus filed under Rule 424 under the Securities Act) as each Holder may request, in conformity with the requirements of the Securities Act, and (C) such other documents as each Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holder, but only during the applicable Effectiveness Period.

     (v) The Company will use its commercially reasonable efforts to register or qualify the Registrable Securities under such other applicable securities or blue sky laws of such jurisdictions as the Holders of a majority of the Registrable Securities reasonably requests as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the relevant Registration Statement is deemed effective by the SEC) and do any and all other acts and things which may be reasonably necessary or advisable to enable the Holders to consummate the disposition in such jurisdictions of the Registrable Securities owned by the Holders; provided, however, that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (v), (B) subject itself to taxation in any such jurisdiction, or (C) consent to general service of process in any such jurisdiction.

     (vi) As promptly as practicable after becoming aware of such event, the Company will notify each Holder of Registrable Securities being offered or sold pursuant to each Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event which comes to the Company’s attention if as a result of such event the prospectus included in such Registration Statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company shall promptly prepare and furnish to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate reports under the Exchange Act) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period, in which case no supplement or amendment need be furnished (or Exchange Act filing made) until the termination of such suspension or Blackout Period.

     (vii) The Company will comply, and continue to comply during the period that each Registration Statement is effective under the Securities Act, in all material respects with the Securities Act and the Exchange Act and with all applicable rules and regulations of the SEC with respect to the disposition of all securities covered by such Registration Statement.

     (viii) As promptly as practicable after becoming aware of such event, the Company will notify each Holder of Registrable Securities being offered or sold pursuant to each Registration Statement of the issuance by the SEC of any stop order or other suspension of effectiveness of such Registration Statement.

     (ix) The Company will permit the Holders of Registrable Securities being offered or sold pursuant to each Registration Statement and their legal counsel, at such Holders’ sole cost and expense to review and have a reasonable opportunity to comment on such Registration Statement and all amendments and supplements thereto at least two Business Days prior to their filing with the SEC.

     (x) The Company will make available for inspection by the Holders and any Inspector retained by the Holders, at the Holders’ sole expense, all records as shall be reasonably necessary to enable the Holders to exercise their due diligence responsibility, and cause the Company’s officers, directors, and employees to supply all information which the Holders or any Inspector may reasonably request for purposes of such due diligence; provided, however, that the Holders shall hold in confidence and shall not make any disclosure of any record or other information which the Company determines in good faith to be confidential, and of which determination the Holders are so notified at the time the Holders receive such information, unless (w) the Holders have, or obtained, knowledge of such information without violation of or protection under any agreements with the Company or, to its knowledge any third party, (x) the disclosure of such record is reasonably necessary to avoid or correct a misstatement or omission in each Registration Statement and a reasonable time prior to such disclosure the Holders shall have informed the Company of the need to so correct such misstatement or omission and the Company shall have failed to correct such misstatement of omission, (y) the release of such record is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction or (z) the information in such record has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement. The Company shall not be required to disclose any confidential information in such records to any Inspector until and unless such Inspector shall have entered into a confidentiality agreement with the Company with respect thereto, containing terms substantially similar to those set forth in this Section 4(c)(x), which agreement shall permit such Inspector to disclose records to the Holders. Each Holder agrees that it shall, upon learning that disclosure of such records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the records deemed confidential. The Company shall hold in confidence and shall not make any disclosure of information concerning the Holders provided to the Company pursuant to this Agreement unless (A) disclosure of such information is reasonably necessary to comply with federal or state securities laws, (B) disclosure of such

information to the SEC’s Staff of the Division of Corporation Finance is reasonably necessary to respond to comments raised by such staff in its review of such Registration Statement, (C) disclosure of such information is reasonably necessary to avoid or correct a misstatement or omission in such Registration Statement, (D) release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, or (E) such information has been made generally available to the public other than by disclosure in violation of this or any other agreement. The Company agrees that it shall, upon learning that disclosure of such information concerning the Holders is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Holders and allow the Holders, at the Holders’ expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

     (xi) The Company will use its commercially reasonable efforts to cause all the Registrable Securities covered by each Registration Statement to be listed or quoted on the principal securities market on which securities of the same class or series issued by the Company are then listed or traded.

     (xii) The Company will provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities at all times.

     (xiii) The Company will cooperate with the Holders of Registrable Securities being offered pursuant to each Registration Statement to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to such Registration Statement and enable such certificates to be in such denominations or amounts as the Investor may reasonably request.

     (xiv) The Company will take all other reasonable actions necessary to expedite and facilitate disposition by the Holders of the Registrable Securities pursuant to each Registration Statement, including without limitation making its chief executive officer, president, chief financial officer and other appropriate officers and personnel available to participate in marketing efforts with respect to any registered underwritten public offering.

     (d) Suspension of Offers and Sales. Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4(c)(vi) or of the commencement of a Blackout Period, such Holder shall discontinue and suspend disposition of Registrable Securities pursuant to any Registration Statement until the Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 4(c)(vi) or notice of the end of the Blackout Period, and, if so directed by the Company, such Holder shall deliver to the Company (at the Company’s expense) all copies (including, without limitation, any and all drafts), other than permanent file copies, then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

     (e) Registration Expenses. All expenses incident to the Company’s performance of or compliance with this Agreement, including without limitation all registration and filing fees,

All Selling Expenses shall be borne solely by the Holders.

     (f) Information by the Holder. The Holder or Holders of Registrable Securities included in any Registration Statement shall furnish to the Company such information required under Regulation S-K under the Securities Act regarding such Holder or Holders and the distribution proposed by such Holder or Holders as the Company may request in writing.

     (g) Indemnification.

     (i) In the event of the offer and sale of Registrable Securities under the Securities Act, the Company shall, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its directors, officers, partners, each other person who participates as an underwriter in the offering or sale of such securities, and each other person, if any, who controls or is under common control with such Holder or any such underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, and expenses to which such Holder or any such director, officer, partner or underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in (A) any Registration Statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or (B) in any materials or information provided to investors by, or with the written approval of, the Company in connection with the marketing of the offering of the Shares (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made not misleading, and the Company shall reimburse the Holder, and each such director, officer, partner, underwriter and controlling person for any legal or any other expenses reasonably incurred by them in connection

with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided that the foregoing shall not apply, and the Company shall not be liable, in any such case (A) to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from such Registration Statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by or on behalf of such Holder specifically stating that it is for use in the preparation thereof, or (B) to the extent that such Holder failed to comply with the terms of the plan of distribution mechanics described in the applicable prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders, or any such director, officer, partner, underwriter or controlling person and shall survive the transfer of such shares by the Holders.

     (ii) As a condition to including any Registrable Securities to be offered by a Holder in any Registration Statement, such Holder agrees to be bound by the terms of this Section 4(g) and to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such Registration Statement and any controlling person within the meaning of the Securities Act of any such underwriter or other Holder, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer or controlling person may become subject under the Securities Act or otherwise, (A) insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement in or omission or alleged omission from such Registration Statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by or on behalf of such Holder specifically stating that it is for use in the preparation thereof, or (B) to the extent that such Holder failed to comply with the terms of the plan of distribution mechanics described in the applicable prospectus. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company, or any such director, officer, partner, underwriter or controlling person and shall survive the transfer of such shares by the Holder, and such Holder shall reimburse the Company, and each such director, officer, legal counsel and accountants, underwriter, other stockholder, and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling and such loss, claim, damage, liability, action, or proceeding; provided, however, that such indemnity agreement found in this Section 4(g)(ii) shall in no event exceed the gross proceeds from the offering received by the Investor.

     (iii) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Section 4(g)(i) or Section 4(g)(ii) (including any governmental action), such indemnified party

shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the indemnifying party 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 its obligations under Section 4(g)(i) or Section 4(g)(ii), except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in the reasonable judgment of counsel to such indemnified party a conflict of interest between such indemnified and indemnifying parties may exist or the indemnified party may have defenses not available to the indemnifying party in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and, after 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 in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend such claim in a diligent manner, other than reasonable costs of investigation. Neither an indemnified nor an indemnifying party shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement, which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to the defense of a claim.

     (iv) In the event that an indemnifying party does or is not permitted to assume the defense of an action pursuant to Section 4(g)(iii) or in the case of the expense reimbursement obligation set forth in Section 4(g)(i) and Section 4(g)(ii), the indemnification required by Section 4(g)(i) and Section 4(g)(ii) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills received or expenses, losses, damages, or liabilities are incurred.

     (v) If the indemnification provided for in this Section 4(g) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall (A) contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense as is appropriate to reflect the proportionate relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission), or (B) if the allocation provided by clause (A) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, not only the proportionate relative fault of the indemnifying party and the indemnified party, but also

the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation.

     (vi) Indemnification similar to that specified in the preceding subsections of this Section 4(g) (with appropriate modifications) shall be given by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities under any federal or state law or regulation or governmental authority other than the Securities Act.

     Section 5. Miscellaneous.
