NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter contained, the parties hereto agree as follows:

1. Purchase and Sale of Assets. On the Closing Date (as hereinafter defined), and subject to the terms and conditions of this Agreement, Seller shall sell, transfer and assign to Purchaser and Purchaser shall purchase and acquire from Seller as of the Effective Time (as hereinafter defined), all right, title, interest and benefit in and to all of the assets, properties and rights used in connection with the operation of the Drilling Business, all of which are described below (the “Assets”), free and clear and expressly excluding all Liens (as hereinafter defined):

If, as of the Effective Time, Seller shall be performing, or be committed to perform, under a drilling contract that is not to be assumed by the Purchaser at Closing, such contract shall be performed by Seller, for its own account, in which event, at the Closing, the Rig(s) which is being used to perform such contract shall nevertheless be sold to Purchaser pursuant to this Agreement and Purchaser and Seller shall enter into a daywork contract in order to allow Seller to perform the drilling services pursuant to such drilling contract, the form of which is attached as Exhibit A hereto (the “Daywork Contract”);

(e) Those contracts, agreements, leases and commitments of Seller set forth on Schedule 1(e) (the “Ancillary Agreements”) and those contracts, agreements, leases and commitments of Seller entered into after the date of this Agreement with respect to which Purchaser provides its written approval and agreement to assume such contracts, all of which shall be expressly assumed by Purchaser by written instrument at Closing, provided that Purchaser shall only be assuming the obligations of Seller which are related to periods after the Closing Date;

(f) All personal property acquired after the date of this Agreement but prior to the Closing Date by Seller used in Seller’s Drilling Business, all of which shall be included in the appropriate Schedules at the time of acquisition.

(g) The term “Assets” does not include, and Seller is not selling to Purchaser, (i) any cash or cash equivalents, deposits, accounts receivable, trademarks, service marks or trade names of Seller, (ii) any interests of Seller in oil and gas properties, any other property or assets including, but not limited to, cash and accounts receivable of Seller not used in the operation of Seller’s Drilling Business, (iii) any asset (including any contract or agreement) not otherwise included in the definition of the term “Assets” in Sections 1(a)-(f), (iv) Seller’s minute books and governance documents, tax returns and historical financial statements, (v) any other books and records of the Seller that relate to the Seller’s Drilling Business (to the extent such other books and records are not Business Records (as hereinafter defined)), (vi) the real property located at 0000 Xxxxxx, Xxxxx Xxxx, Xxxxxx 00000, (vii) any assets that Seller is required by law to retain and (viii) the 2001 Audi A6 automobile, (ix) the xxxxxxx that existed on or about April 17, 2004 and any insurance proceeds received as a result of the destruction of such xxxxxxx and (x) those assets described on Schedule 1(h) (collectively, the “Excluded Assets”).

2. Assumption of Liabilities.

(iii) Resolutions of the board of directors and the Shareholder of Seller evidencing the authorization of the execution, delivery and performance of this Agreement and each of the other agreements contemplated hereby by Seller and the Shareholder and the consummation of the transactions contemplated hereby and thereby, certified by the Secretary of Seller;

(iv) A certificate dated as of the Closing Date and signed by the President of Seller and the Shareholder to the effect that the representations and warranties of Seller and the Shareholder set forth in this Agreement, as of the date of this Agreement and as of the Effective Time, are true and correct in all material respects and that all covenants, agreements and conditions required by this Agreement to be performed or complied with prior to or at the Closing have been so performed or complied with;

the States of Colorado, Oklahoma and Kansas and any other applicable States, counties and jurisdictions (which searches shall include a search of judgments and abstracts), showing that the Assets are free and clear of any Liens or executed UCC-3 termination statements (or such other releases which are necessary to release such Liens,) releasing Liens or that are reflected in such searches;

(vii) Such additional certificates, proceedings, instruments and other documents as Purchaser may reasonably request to evidence compliance by Seller and the Shareholder with this Agreement and applicable legal requirements and the performance and satisfaction by Seller, at or prior to the time of Closing, of all agreements then to be performed and all conditions then to be satisfied by Seller or the Shareholder;

(xii) With respect to any Drilling Contract, Ancillary Agreement or any other contract or commitment, the Seller shall provide written consents or approvals by the parties to such agreements, authorizing the assignment of same from the Seller to Purchaser; to the extent that any such consent or approval is necessary for assignment thereof; provided, however, in the case of any such Ancillary Agreement or any other contract or commitment (including a Drilling Contract) which is not by its terms assignable and with respect to which a consent to assignment is not obtained by the Closing Date (each, an “Unassigned Contract”), Seller agrees to use its best efforts to obtain, or cause to be obtained, subsequent to the Closing Date, any written consents necessary to convey to Purchaser the benefit and obligations thereof. Purchaser shall cooperate with Seller, in such manner as may be reasonably requested, in connection therewith. If Seller is unable to obtain such necessary written consents for the remaining term of any such Unassigned Contract, Seller shall cooperate with Purchaser in any reasonable arrangement proposed by Purchaser that provides the Purchaser with the benefits, rights or interests which inure to Seller under any such Unassigned Contract and requires Purchaser to promptly make any payments and perform any obligations, on Seller’s behalf, due under any such Unassigned Contract. Purchaser agrees to indemnify and hold harmless Seller and each of its affiliates from and against any and all Damages (as defined in Section 12)

5 incurred by it in connection with Purchaser’s performance of Seller’s obligations under such Unassigned Contracts; provided, however, that such Damages are not (i) the result of Seller’s default hereunder or a default under or breach of such Unassigned Contract which occurs prior to Closing or (ii) based upon a breach of Seller’s agreement with a third party not to assign such contract. However, Purchaser may refuse to perform Seller’s obligations under an Unassigned Contract, in which case the Seller will be solely responsible for such Unassigned Contracts. In the event that the Unassigned Contract in question is a Drilling Contract, then the Rig being used to perform such Drilling Contract shall be contracted to Seller pursuant to the provisions of Section 1(d) hereof with respect to unassumed drilling contracts.

(i) The Xxxx of Sale and Assignment and Assumption Agreement;

(ii) The Employment Agreement;

(iii) The Non-Competition Agreement;

(iv) If, at the time of Closing, any of the Rigs are being operated by Seller and pursuant to the terms of this Agreement the related drilling contract which is being performed by Seller is not to be transferred to the Purchaser, a Daywork Contract, with respect to each affected Rig(s) to allow the Seller to complete such drilling contract(s); provided, however, that notwithstanding anything herein to the contrary, the Purchaser shall have no obligation to enter into any Daywork Contract unless the Seller demonstrates that it is in compliance with the insurance provisions set forth in the Daywork Contract at the time of Closing, and if Seller is not in compliance with such insurance provisions the Seller may not refuse to Close on the basis that Purchaser will not enter into such Daywork Contract, in which event at Closing the Seller will be solely responsible for performing the drilling contract (or portion of a drilling contract) which would have otherwise been performed under a Daywork Contract;

(v) Resolutions of the general partner of Purchaser evidencing the authorization of the execution, delivery and performance of this Agreement by Purchaser and the consummation of the transactions contemplated hereby, certified by the Secretary of the general partner of Purchaser;

6 (vi) A certificate dated as of the Closing Date and signed by the President of the general partner of Purchaser to the effect that the representations and warranties of Purchaser set forth in this Agreement, as of the date of this Agreement and as of the Effective Time, are true and correct in all material respects and that all covenants, agreements and conditions required by this Agreement to be performed or complied with prior to or at the Closing have been so performed or complied with;

(c) Delivery of Assets. At the Closing, Seller shall deliver and transfer title to the Assets other than the Unassigned Contracts to Purchaser free, clear and discharged of and from any and all Liens. The Rigs, to the extent they are not then performing drilling services, shall be rigged down at the locations of the last completed drilling contracts and delivery of the Rigs shall be deemed to occur at Closing at such locations, or at the Yard if mutually agreed by the parties. To the extent that the Rigs are at the time of the Closing Date performing drilling services under a Drilling Contract, delivery of the Rigs shall occur at the location that the Drilling Contract is being performed. The Support Agreements, Drilling Contracts, Ancillary Agreements and Business Records shall be appropriately boxed and packaged for pick-up by Purchaser at Seller’s office in Denver, Colorado and delivery shall be deemed to occur at Closing at such location. Delivery of the Yard Equipment, Office Equipment and Vehicles shall occur at Closing at the Yard. The certificates of title to the Vehicles shall be delivered at Closing in San Antonio, Texas or at a mutually agreeable location. The above notwithstanding, to the extent that at Closing any Rig is being used to perform a drilling contract on behalf of Seller and the use of the Rig(s) to perform such drilling contract is to be provided to Seller under a Daywork Contract, such Rig(s) shall not be rigged down but shall be deemed delivered to Purchaser at the Closing at its then present location. It is expressly agreed that the title to, and the risk of loss of, all of the Assets shall pass to Purchaser at the Effective Time, except that only risk of loss and not title shall pass to Purchaser with respect to the Unassigned Contracts which the Purchaser elects to perform. In the event that, pursuant to the terms of this Agreement, Seller obtains the use of any of the Rigs under a Daywork Contract, Seller agrees to maintain all insurance required by the Daywork Contract.

5. Covenants, Representations and Warranties of Seller and Shareholder. Seller and the Shareholder hereby, jointly and severally, covenant, represent and warrant to Purchaser as follows and acknowledge that Purchaser is relying upon such representations and warranties in entering into this Agreement:

(a) Legal Existence of Seller. Seller is a corporation duly organized and validly existing under the laws of the State of Kansas and has the power to carry on its business as now being conducted. Seller is not qualified as a foreign corporation in any jurisdiction other than the State of Oklahoma and is not required to do so. There are no other jurisdictions in which Seller’s failure to be so qualified would have a material adverse effect on the Drilling Business, the Assets or Purchaser’s operation of the Drilling Business or the Assets after the Closing Date. The Shareholder is the sole shareholder of Seller and has all voting rights with respect to the capital stock of Seller.

(b) Legal Authority. The execution, delivery and performance of this Agreement and each of the other agreements contemplated hereby, and the obligations undertaken by Seller herein, have been duly authorized and approved by the board of directors of Seller and have been consented to by the Shareholder.

(c) No Violation. This Agreement constitutes a valid and binding obligation of Seller and the Shareholder enforceable against Seller and the Shareholder in accordance with its terms and this Agreement and all transactions contemplated hereby will not result in the violation of any terms of the Articles of Incorporation or the Bylaws of Seller or any applicable law or, except for the requirement for any consent or approval set forth in Schedule 5(g) below, any agreement to which Seller is a party or by which any of the Assets or Seller’s Drilling Business is bound.

(d) Title to Assets. Seller owns all of the Assets, free and clear of all liens, charges, privileges, equities, pledges, mortgages, leases, options, assessments, judgments, security interests, restrictions and other encumbrances of any kind whatsoever (“Liens”), other than those Liens disclosed in Schedule 5(d) (the “Existing Liens”), and Seller has, or as of the Closing Date will have, full right, power, title and authority to sell, transfer and convey the Assets, to Purchaser, free and clear of all Liens, including the Existing Liens and therefore, at Closing the Seller will transfer the Assets to the Purchaser free and clear of all Liens.

(e) No Litigation. Except as described on Schedule 5(e), there presently exists no litigation, proceeding, action, claim, arbitration or investigations (a “Proceeding”) at law, in equity or otherwise, pending or, to Seller’s or the Shareholder’s knowledge, threatened against Seller or affecting any of the Assets or the Drilling Business or the Real Property. Neither Seller nor the Shareholder is subject to any notice, writ, injunction, order, or decree of any court, agency, or other governmental authority affecting the Seller, the Assets, the Drilling Business or the Real Property. Neither Seller nor the Shareholder has been served with process or otherwise received formal notice with respect to, nor, to Seller’s or the Shareholder’s knowledge, has Seller or the Shareholder been threatened with, any litigation or judicial, administrative, arbitration or other Proceeding affecting the Seller, the Assets, the Drilling Business or the Real Property.

(f) Brokers. Except as set forth in Schedule 5(f), no agent, broker, person or firm acting on behalf of Seller or the Shareholder is, or will be, entitled to any commission or broker’s or finder’s fees from any of the parties hereto, or from any

affiliate of the parties hereto, in connection with any of the transactions contemplated by this Agreement.

(g) Contracts/Assignments. The lists of contracts and agreements identified on Schedules 1(c), (d) and (e) are complete and accurate lists of all contracts and agreements between Seller and any other person related to the Seller’s Drilling Business. Each of the contracts and agreements described or referred to in Schedules 1(c), (d) and 1(e) are valid and binding obligations of Seller and the other party or parties thereto. None of the parties to any of such contracts or agreements has terminated, canceled, or modified any of such contracts or agreements or given notice that it intends to do so and, to the best of Seller’s and Shareholder’s knowledge, neither Seller nor any other party is in default thereunder or will be with the giving of notice, the passage of time or both. During the Review Period (as defined in Section 7(a)), Seller agrees that it will not, without the written consent of the Purchaser, modify any of the contracts which Purchaser is to assume at Closing or otherwise perform after Closing. Each of the contracts and agreements identified on Schedules 1(c), (d) and (e) may be freely assigned by Seller to Purchaser without the requirement of any consent or approval, except as set forth in Schedule 5(g). True and complete copies of the contracts and agreements identified on Schedules 1(c), (d) and (e) have been provided to Purchaser and true and complete copies of any Drilling Contracts entered into after the Effective Date will be provided to Purchaser when such Drilling Contracts are executed by Seller. To the extent that performance by Seller of any Drilling Contract has commenced, Seller is performing such Drilling Contract in material compliance with its terms and there are no defaults thereunder or which would exist with the passage of time, the giving of notice or both and, to the best of Seller’s knowledge, there are no material adverse circumstances which exist or that the Seller has reason to believe will exist, which relate to the performance thereof, the completion of such Drilling Contract in accordance with its terms, and the receipt of payment for the performance thereof.

(h) Personal Property. The Assets described in Schedules 1(a) and 1(b) attached hereto are a full and complete list of all the operating assets of the Drilling Business and along with the miscellaneous hand tools and other spare equipment not required to be listed on Schedules 1(a) and 1(b), constitute all of the tangible and intangible personal property used by Seller in connection with Seller’s Drilling Business (except as qualified below). Seller has delivered or will deliver at Closing all support, maintenance, warranty, and similar agreements related to the Assets. Seller has maintained the Assets in good operating condition, and, at the time the Assets are delivered to Purchaser at the Closing, will be in good operating condition. Neither Seller nor the Shareholder has any knowledge of any material damage to or defect in any of the Assets. Subject to the foregoing, it is expressly agreed that all of the Assets are being sold to Purchaser in “AS-IS,” “WHERE-IS” condition without warranty or guarantee of any kind or nature. In addition, at all times prior to Closing, the Seller shall provide Purchaser with timely, accurate reports specifying any loss or damage to any of the Assets, including the Rigs and Yard Equipment.

(i) Permits and Approvals. Except as set forth in Schedule 5(i), Seller has no permits, approvals, authorizations, licenses, consents, certifications, qualifications or

clearances held, used or required in connection with Seller’s operation of the Drilling Business or ownership or use of the Assets and the Real Property and, to Seller’s and Shareholder’s knowledge none (other than those set forth in Schedule 5(i)) are required in connection with Seller’s operation of the Drilling Business.

(j) Compliance with Laws. Seller’s operation of the Drilling Business, ownership and use of the Assets and the Real Property and Seller’s performance under the Drilling Contracts has been conducted in material compliance with all statutes, ordinances, codes, restrictions, regulations and other governmental requirements, including all environmental laws.

(k) Taxes. The Assets are not in any manner encumbered by any Liens arising out of unpaid taxes except for Liens for current taxes not yet due and payable. All taxes owed by Seller or relating to the Drilling Business, the Assets or the Real Property have been paid, and Seller has filed all federal, state and other tax returns and reports required to be filed. No claim has ever been made by an authority in a jurisdiction where Seller does not file tax returns or have tax returns filed on its behalf that it is or may be subject to taxation by that jurisdiction. Seller has withheld and paid all taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, stockholder or other third party. No taxing authority is expected to assess any additional taxes for any period for which tax returns have been filed or for which tax returns should have been filed. There is no claim, either written or otherwise, concerning any tax liability of Seller. Seller’s Drilling Business constitutes a separate and identifiable business of Seller and the income and expenses attributable to Seller’s Drilling Business could be separately established from the books of account or records of Seller.

(l) True and Correct Copies. Seller has delivered or made available or, prior to the commencement of the Review Period will deliver or make available, to Purchaser true, correct, and complete copies of all contracts, agreements and documents referred to in this Agreement, together with all modifications thereof and amendments thereto, and all current maintenance records related to the Assets. It is expressly understood that Seller, prior to the execution of this Agreement, has made available to the Purchaser, true and correct copies of (i) all Ancillary Agreements and Support Agreements in effect as of the Effective Date, (ii) certificates of insurance with respect to all insurance policies held by Seller, and (iii) any lawsuit, demand, order or other complaint relating to the Seller or the Drilling Business. At the commencement of the Review Period, Seller shall make available to Purchaser true and correct copies of (i) all Drilling Contracts and Ancillary Agreements which are to be assumed or performed by the Purchaser, (ii) daily drilling reports with respect to Seller’s Drilling Business, (iii) all maintenance and rig inspection records relating to the Assets, (iv) all safety records relating to the Drilling Business (for the prior one year), (v) all personnel records for all employees, and (vi) all other documents referenced in this Agreement which have not previously been delivered to the Purchaser, including copies of all insurance policies listed on Schedule 5(m).

(m) Insurance. Seller has delivered or made available to Purchaser true, correct, and complete copies of certificates of insurance with respect to all insurance

policies and contracts related to or material to Seller’s ownership and use of the Assets and the Real Property, if any, together with all modifications thereof and amendments thereto, and Schedule 5(m) contains a list of all such policies and contracts (including insurer, named insured and type of coverage) for fire, casualty, liability and other forms of insurance maintained by, or for the benefit of Seller, in connection with Seller’s Drilling Business, the Assets and the Real Property. Except as disclosed on Schedule 5(m), no pending or unresolved claims exist under any policy or contract of insurance related to Seller’s Drilling Business, its ownership and use of the Assets, or the Real Property and, to Seller’s and Shareholder’s knowledge, no facts or circumstances exist pursuant to which any such claim could be made. All such policies, if any, are in full force and effect. Seller has not received any notice of cancellation, non-renewal or significant premium increases with respect to any policy. All premiums due prior to the date hereof for the period prior to the date hereof with respect to such policies have been timely paid, and all premiums due before the Closing Date for periods between the date hereof and the Closing Date will be timely paid. Notwithstanding the foregoing, Purchaser acknowledges that Seller does not insure casualty loss or damage to the Assets.

(n) Employee Benefit Plans.

(i) Each Seller Benefit Plan (as hereinafter defined) has been administered and operated within the terms of the applicable controlling documents and with the applicable provisions of ERISA (as hereinafter defined), the Internal Revenue Code of 1986, as amended (the “Code”), and all other applicable laws. For purposes of this Agreement, “Seller Benefit Plan” means (A) all “employee benefit plans”, as such term is defined in section 3(3) of ERISA including, but not limited to, all employee benefit plans which are not subject to ERISA, that are or have been sponsored, maintained, or contributed to by Seller or any Commonly Controlled Entity and (B) stock option, stock purchase or other stock-based plans, bonus or incentive award plans, employment or casualty agreements, severance pay policies or agreements, fringe benefit plans or programs, deferred compensation agreements, supplemental income arrangements, vacation plans, and all other employee benefit plans, programs, policies, practices, agreements and arrangements (written or unwritten) not described in (A) above that are or have been sponsored, maintained or contributed to by Seller or any Commonly Controlled Entity.

(ii) Except as described in Schedule 5(n), neither the Seller nor any corporation, trade, business or entity under common control with the Seller or its subsidiaries, within the meaning of section 414(b), (c) or (m) of the Code or section 4001 of the Employee Retirement Income Security Act of 1974 (“ERISA”) (“Commonly Controlled Entity”), sponsors, maintains or contributes to, or has sponsored, maintained or contributed to, within six years prior to the Closing Date, any “multiemployer plans” as such term is defined in Section 3(37) of ERISA or any “employee pension benefit plan,” as such term is defined in Section 3(2)(A) of ERISA, that is subject to Title IV of ERISA.

(iii) Seller and/or its Commonly Controlled Entities maintain the

“group health plan(s),” as that term is defined in Section 607(1) of ERISA, described in Schedule 5(n) and shall continue to maintain such group health plans for a period of thirty (30) days following the Closing Date. All such group health plans of Seller and/or of any Commonly Controlled Entity have been operated in material compliance with the requirements of Part 6 of Title I of ERISA and of Sections 4980B (and its predecessor) and 5000 of the Internal Revenue Code of 1986, and Seller and/or its affiliates have provided, or will have provided before the Closing Date, to individuals entitled thereto all required notices and coverage pursuant to such Part 6 and Section 4980B with respect to any “qualifying event” (as defined therein) occurring prior to the Closing Date.

(o) Labor Matters.

(i) Neither Seller nor any of its affiliates is a party to (nor is it bound as a successor entity by) any collective bargaining agreements. Neither Seller nor any of its affiliates has agreed to recognize any union or other collective bargaining representative, nor has any union or other collective bargaining representative been certified as the exclusive bargaining representative of any of the employees of Seller or any of its affiliates. There is no question concerning representation as to any collective bargaining representative concerning employees of Seller or any of its affiliates.

7. Actions Before Closing.

(a) Access During Review Period. During the period from the date of this Agreement to the Closing Date (the “Review Period”), Seller shall, and the Shareholder shall cause the Seller to, afford Purchaser and its counsel and other representatives reasonable access during normal business hours to Seller’s contracts, properties and facilities which form a part of the Assets, shall assist Purchaser in its discussions with customers, suppliers and employees of Seller’s Drilling Business, and Seller shall instruct its officers, employees, accountants and agents to fully cooperate with Purchaser and its counsel, accountants, lenders and other representatives in its investigation and to furnish such additional information as Purchaser and its counsel and other representatives may from time to time reasonably request including, without limitation, any request for information made by financiers from whom Purchaser is seeking financing, if any. The Shareholder and Seller specifically covenant that during the Review Period, the Shareholder and Seller shall permit Purchaser to conduct such tests and investigations of the Drilling Business, the Assets and the Real Property, at Purchaser’s sole cost and expense, as Purchaser may reasonably request, provided that such tests and investigations do not materially interfere with Seller’s conduct of the Drilling Business or damage or alter any of the Assets or Real Property. In addition, Purchaser shall, at Purchaser’s sole cost and expense, be permitted to make abstracts from, or take copies of, such

documentation relating to the Drilling Business, the Assets and the Real Property as may be reasonably required by Purchaser. Access shall include the right to conduct an environmental assessment of the Yard, the Real Property and the Building. Seller and the Shareholder shall provide documentation and narrative information regarding Seller, the Assets and Seller’s Drilling Business, which will assist Purchaser with its due diligence. As requested by Purchaser, during the Review Period, Seller shall provide Purchaser with copies of Seller’s business records which relate to the Drilling Business as conducted by Seller (collectively, “Business Records”), including, as requested, employee records for those Employees (as defined below) to be hired by Purchaser, maintenance records, safety records, drilling records, bit record files, drilling reports and all records pertaining to the Drilling Contracts which are to be assumed or performed by Purchaser. It is understood that during the Review Period, Seller is not required to make copies of all Business Records, but rather only portions of the Business Records requested by Purchaser. After Closing Seller agrees to provide Purchaser with access to all Business Records as reasonably requested by Purchaser after Closing;

(b) Interim Conduct of the Drilling Business. Seller shall conduct Seller’s Drilling Business only in the ordinary and usual course, consistent with past practices. Seller shall pay when due, its obligations relating to the Drilling Business, including its obligations to employees, suppliers and contractors. Seller agrees that prior to executing or amending any Defined Contract (as defined below), it will provide Purchaser with a copy of such Defined Contract and provide all other information relating thereto as reasonably requested by Purchaser. “Defined Contract” means any drilling contract or any other agreement between Seller and any third party which relates to Seller’s Drilling Business and which may be performable in whole or in part after Closing. Unless Purchaser provides its written consent to the entering into of any such Defined Contract (which consent shall not be unreasonably withheld or delayed), Purchaser shall have no obligation to assume (or otherwise perform) any such Defined Contract at or after Closing. Additionally Purchaser shall not withhold its written consent to a Defined Contract that is a drilling contract if it contains daywork, footage or turnkey rates substantially equivalent to the prevailing market rates, as reasonably determined by Purchaser, at the time they are entered into and do not contain any terms and conditions which, when taken as a whole, are not at least as favorable in any material respect as those contained in the other Drilling Contracts listed in Schedule 1(d). To the extent that Purchaser provides its written consent to the entering into of any such Defined Contract, such Defined Contract shall be added to Schedules 1(d) or 1(e), as applicable. Without limiting the generality of the foregoing, Seller hereby covenants to Purchaser that insofar as Seller’s Drilling Business is concerned, Seller will use commercially reasonable efforts to:

(i) Preserve the Drilling Business and Seller’s relationships with suppliers, customers, employees, creditors, and others having business dealings with the Drilling Business;

(ii) Maintain in full force and effect its existing policies of insurance listed on Schedule 5(m);

(iii) Maintain the Assets in good operating condition and repair, and repair any of the Assets which are not in good operating condition as of the date of this Agreement so that such Assets are placed in good operating condition;

(iv) Continue performance in the ordinary course of its obligations under the Drilling Contracts and Ancillary Agreements;

(v) During the Review Period and subject to reasonable advance notice to the Seller and cooperation in scheduling the same, permit employees or other representatives of Purchaser to consult with Seller’s employees who are employed in the Drilling Business in the performance of their jobs, provided that any such discussions will be performed in a manner that will not unreasonably disrupt the operation of Seller’s Drilling Business; and

(vi) Avoid entering into any agreement relating to the Drilling Business which does not by its terms, terminate or expire (whether by performance or otherwise) at or prior to the Closing Date, whether a drilling contract or otherwise, which prohibits the transfer or assignment of such agreement to Purchaser.

(c) Purchaser’s Approval of Certain Transactions. Seller hereby covenants to Purchaser that during the Review Period, or during such shorter period as indicated below, Seller shall not do any of the following acts without the prior written consent of Purchaser, which consent shall not be unreasonably withheld or delayed:

(i) Sell, transfer, encumber or assign any of the Assets (except to Purchaser in accordance with this Agreement or in connection with the replacement of such Assets in the ordinary course of business);

(ii) Enter into any Drilling Business transaction, contract or commitment outside of the ordinary course of business;

(iii) Enter into any drilling contract which contains any terms and conditions which, when taken as a whole, are not at least as favorable in any material respect as those contained in the other Drilling Contracts listed in Schedule 1(c); provided, however, that drilling contracts that contain Daywork, footage or turnkey rates substantially equivalent to the prevailing market rates, as reasonably determined by Purchaser, at the time they are entered into shall not violate the foregoing provision on the basis of the rates charged;

(iv) Give any Employee an increase or change in wages, salary or benefits or make any promise with respect to any such increase or change in wages, salary or benefits; provided, however, that Seller may (after notifying Purchaser in writing and obtaining Purchaser’s consent, which consent will not be unreasonably withheld or delayed) increase or change the wages, salary or benefits of those employees, or make commitments to do so where the Seller reasonably believes in the exercise of its good faith it is necessary to do so in

order to remain commercially competitive with prevailing wages, salaries and benefits; or

(v) Enter into any agreement which would result in the Shareholder not owning 100% of the capital stock of Seller.

(d) Consent to Assignment. Seller hereby covenants to Purchaser that Seller will use its best efforts to obtain, prior to the Closing, the consents and approvals that are necessary to assign to Purchaser the Drilling Contracts and Ancillary Agreements. Any and all such approvals and consents shall be in writing, signed by the person entitled to consent or approve, and shall be delivered to Purchaser at or prior to Closing.

(e) Schedule Update. Seller and Purchaser shall update by amendment or supplement each of the Schedules referred to herein and any other disclosure in writing from either party required by this Agreement to be disclosed by Seller or Purchaser promptly upon any change in the information set forth in such Schedules or other disclosures. Each party hereby represents and warrants to the other that such Schedules and such written disclosures up to and including the date of Closing, as so amended or supplemented by them, shall be true and correct as of the dates thereof and as of the Closing Date; provided, however, that the inclusion of any information in any such amendment or supplement, not included in the original Schedule or other disclosure at or prior to the date of this Agreement, shall not limit or impair any right that either party might otherwise have respecting the representations and warranties of Seller originally contained in this Agreement.

(f) Reports. During the Review Period, on a daily basis, Seller shall provide Purchaser, via telefax, with the daily drilling reports pertaining to the operation of the Drilling Business. In addition, as situations occur, Seller shall promptly notify Purchaser in writing with respect to any material damage to the Assets or any material adverse change in the Drilling Business or any Drilling Contract (or any facts or circumstances that could result in material adverse damage to Seller’s Drilling Business or any Drilling Contract).

(g) No Negotiation. Until such time, if any, as this Agreement is terminated pursuant to Section 14 hereof, Seller and the Shareholder shall not, directly or indirectly solicit, initiate, or encourage any inquiries or proposals from, discuss or negotiate with, provide any non-public information to, or consider the merits of any unsolicited inquiries or proposals from, any Person (other than Purchaser) relating to any transaction involving the sale of the Assets, or any of the ownership interest in Seller, or any merger, consolidation, business combination, or similar transaction involving Seller. The Shareholder shall, and shall cause Seller to, promptly communicate to Purchaser the terms of any proposal received or the fact that Seller has received inquiry with respect to, or has participated in discussions or negotiations in respect of, any such transaction, and the identity of any persons who initiated or participated in such discussions or negotiations.

Such schedule shall be added to this Agreement as Schedule 10(c) at the time it is provided to Purchaser.

In addition, to the extent that any consent or approval was not obtained prior to Closing and Purchaser nevertheless elected to proceed with Closing, Seller shall continue to use its best efforts to obtain from such person or persons any such

consents or approvals. Notwithstanding the foregoing, Purchaser agrees to take all actions reasonably requested by Seller to effect the assignments of any of the Drilling Contracts or Ancillary Agreements.

Further, Seller, the Shareholder and the Trust Beneficiaries acknowledge that each of them will directly or indirectly benefit from the transactions contemplated by this Agreement. Seller, the Shareholder and each of the Trust Beneficiaries agree that for a period of five (5) years from the Closing, they will not, directly or indirectly, engage in the contract drilling business anywhere in the States of Oklahoma, Kansas, Colorado and/or Texas whether as an investor, owner, employee, partner, shareholder, lender, consultant or in any other capacity whatsoever.

(iv) Notwithstanding anything to the contrary contained in this Agreement, Purchaser acknowledges and agrees that for all purposes related to the foregoing disclosure prohibitions, “third parties” shall include any officers, directors, employees, representatives, agents or advisors of Seller. However, “third parties” do not include the Shareholder’s and Seller’s lawyers and accountants, nor during the Review Period only, does it include directors, agents, advisors, employees, officers and representatives of Seller.

(v) Mutual Benefit. Seller, the Shareholder, the Trust Beneficiaries and Purchaser acknowledge and agree that they will benefit directly from the sale of the Assets, and that the parties would not enter into this Agreement and purchase the Assets without the agreements set forth in Sections 10(g) and (h) as the same are necessary to protect the goodwill associated with Seller’s Drilling Business. Therefore, Seller, the Shareholder, the Trust Beneficiaries and Purchaser agree that in the event of a breach of the covenants contained in Sections 10(g) and (h), the non-breaching party shall suffer material and irreparable harm, and any remedy at law for such breach will be inadequate and that the non-breaching party or its successors or assigns may seek injunctive relief or specific performance of its rights therein described without any requirement of posting a bond; provided, however, that they shall not be limited to the remedy of injunctive relief or specific performance in the event of a breach, but may seek any other remedies available to them at law or at equity, including the recovery of attorney’s fees.

(i) Xxxxxxx Maintenance. Purchaser shall allow Seller to maintain, at no cost to Seller, the damaged xxxxxxx referenced in Section 1(g)(xi) above until such time as the litigation referenced in Schedule 5(e) is concluded, so long as such maintenance (and removal as provided below) does not directly or indirectly interfere with the Drilling Business to be operated by Purchaser after the Closing Date. At the conclusion of such litigation, Purchaser shall allow Seller reasonable time to remove the xxxxxxx at Seller’s sole cost and expense.

11. Allocation of Proceeds from Drilling Contracts. Seller and Purchaser shall allocate any proceeds received after Closing with respect to a dayrate Drilling Contract based on the number of days of work completed on such Drilling Contract up to the Closing Date and the number of days of work completed on such Drilling Contract on the day of and after the Closing Date. Seller shall receive the portion of revenue attributable to the days of work completed up to the Closing Date and Purchaser shall receive the portion of revenue attributable to the days of work completed on the day of and after Closing. With respect to any multiple well footage or

turnkey drilling contract assumed by the Purchaser, Seller shall receive that portion of the proceeds which relates to xxxxx drilled by the Seller, and the Purchaser shall receive that portion of the proceeds which relates to the drilling of xxxxx by the Purchaser.

12. Indemnification.

14. Termination and Effect of Termination.

(a) Termination. This Agreement may, by notice given prior to or at the Closing, be terminated:

(i) By either party if a material breach of any provision of this Agreement has been committed by the other party and such breach has not been waived or cured to the reasonable satisfaction of the non-breaching party, after the receipt of written notice of such breach and a ten (10) day opportunity to cure;

(ii) By Purchaser if any of the material conditions under Section 8 hereof have not been satisfied as of the Closing Date, or if satisfaction of such a material condition is or becomes impossible (other than the willful and intentional failure of Purchaser to comply with its obligation under this Agreement), and Purchaser has not waived such condition on or before the Closing Date;

(iii) By Seller, if any of the material conditions in Section 9 hereof have not been satisfied as of the Closing Date, or if satisfaction of such a material condition is or becomes impossible (other than the willful and intentional failure of Seller to comply with its obligation under this Agreement), and Seller has not waived such condition on or before the Closing Date;

(b) Effect of Termination. Each party’s right of termination under this Section 14 is in addition to any other rights it may have under this Agreement or

otherwise, and the exercise of a right of termination will not be an election of remedies.

15. Specific Performance; Remedies. Each of the parties hereby agrees that the transactions contemplated by this Agreement are unique, and that each party shall have, in addition to any other legal or equitable remedy available to it, the right to enforce this Agreement by decree of specific performance.

Without limiting the generality of foregoing, the term “Cause” shall also include any breach or affirmative acts which are reasonably believed to be a threatened breach of any of the provisions of Article 6 or the Non-Competition Agreement, or the assertion by Xxxxx in any judicial or other proceeding that the Non-Competition Agreement (or any provision thereof) is unenforceable or should be reformed.

(d) Without Cause.

(i) This Agreement shall terminate upon the Company providing thirty (30) days written notice to Xxxxx that the Company is terminating the Agreement without Cause, at any time during his employment; provided, however, that the Company shall be required to pay severance in accordance with the severance provisions in Section 5.2.

(ii) Any termination of this Agreement by the Company which is not for Cause, or which does not result from the death of Xxxxx, or the disability of Xxxxx, shall be deemed to be a termination without Cause. Further, in the event that the Company communicates a notice of termination for Cause, and an arbitrator determines that no Cause exists or existed for the notice of termination for Cause to be communicated by the Company to Xxxxx, then such notice shall be deemed to have been a communication of a notice of termination without Cause, as appropriate, for all purposes under this Agreement.

(e) Good Reason. Xxxxx shall have the right to terminate this Agreement for any breach of this Agreement by the Company which shall include but not be limited to (i) materially changing the duties assigned to Xxxxx beyond those contemplated in Section 2.1, (ii) failing to pay the compensation or provide the benefits provided in Article 3 of this Agreement, or (iii) requiring Xxxxx to relocate to any location other than the Denver metropolitan area; provided, however, that the Company shall be furnished ten (10) days notice of such breach and an opportunity to cure such breach (any such termination constituting a termination for “Good Reason”).

5.2 Severance. Upon termination by the Company without Cause or termination by Xxxxx with Good Reason, if such termination occurs during the initial Employment Term (i.e. the two year period commencing on the date hereof and ending on the day immediately preceding the second anniversary of such date), the Company shall pay to Xxxxx, as severance pay (“Severance

Pay”), the total remaining salary due Xxxxx for the entire remaining initial Employment Term (i.e. the remaining portion of the salary owed to Xxxxx for the initial two year term commencing on the date hereof and ending on the second anniversary of such date). The Severance Pay shall be paid to Xxxxx in equal monthly payments over the remaining portion of the initial Employment Term. The Severance Pay specified in this Section 5.2 shall be in addition to the payment of any and all unpaid salary due Xxxxx through the date of termination. In addition, the Company shall either (i) continue to provide Xxxxx at the Company’s sole cost and expense with the same benefits as he had while employed through the end of the Employment Term or (ii) to the extent it is not possible to provide Xxxxx with the same benefits he had while employed, the Company shall pay or reimburse Xxxxx for the actual cost of Xxxxx obtaining substantially similar benefits through the end of the Employment Term.

ARTICLE 6

CONFIDENTIALITY; NON-COMPETITION AGREEMENT

6.1 Confidentiality. Xxxxx acknowledges that during his employment with Seller and his employment with the Company, Seller and the Company have and will continue to disclose, to him the confidential affairs and proprietary information of the Company and its subsidiaries and affiliates, which is developed by and belongs to the Company and its subsidiaries and affiliates including, without limitation, the following information (collectively, the “Confidential Matters”): (i) any and all trade secrets (as such term may be defined under any and all applicable law) concerning the business and affairs of the Company and its subsidiaries and affiliates including, without limitation, product specifications, data, know-how, formulae, compositions, processes, designs, sketches, photographs, graphs, drawings, samples, inventions and ideas, past, current and planned research and development, current and planned manufacturing and distribution methods and processes, acquisition opportunities, customer lists, current and anticipated customer requirements, price lists, market studies, business plans, computer software and programs (including object code and source code), computer software and database technologies, systems, structures and architectures (and related processes, formulae, compositions, improvements, devices, know-how, inventions, discoveries, concepts, ideas, designs, methods and information) and any other information, however documented, of the Company and its subsidiaries and affiliates that is a trade secret, (ii) any and all information concerning the business and affairs of the Company and its subsidiaries and affiliates (which includes historical financial statements, financial projections and budgets, historical and projected sales, capital spending budgets and plans, the names and backgrounds of key personnel, personnel training and techniques and materials), however documented and (iii) any and all notes, analysis, compilations, studies, summaries, and other material prepared by or for the Company and its subsidiaries and affiliates or containing or based, in whole or in part, on any information included in the foregoing. Xxxxx further acknowledges and agrees that he would be unable to perform his duties and responsibilities for the Company but for the Company’s disclosure of the Confidential Matters and that the Company would not enter into this Agreement, the transactions contemplated by the Asset Purchase Agreement, hire Xxxxx as an

employee of the Company or disclose any Confidential Matters to Xxxxx without the promises made by Xxxxx in this Section 6.1. Finally, Xxxxx acknowledges and agrees that the Company used, and will continue to use, its own resources to provide training to Xxxxx that allows Xxxxx to perform his duties and responsibilities; provided, however, that neither the foregoing nor anything else in this Agreement shall prohibit or restrict Xxxxx from using the general knowledge and skills learned and developed by Xxxxx in performing his employment duties to the extent such knowledge and skills would be known to another person performing similar duties at another company and/or not otherwise covered in the definition of Confidential Matters above.

In light of the foregoing, Xxxxx agrees:

(a) To keep secret all Confidential Matters of the Company and its subsidiaries and affiliates, and not to disclose such Confidential Matters to anyone outside of the Company or its subsidiaries and affiliates, or otherwise use such Confidential Matters or use his knowledge of such Confidential Matters for his own benefit or for the benefit of any third party, whether Xxxxx has such Confidential Matters in his memory or embodied in writing or other physical form including, without limitation, use of the trade secrets, trade names or trademarks of the Company, either during or after the Employment Term, except in the performance of Xxxxx’x employment duties for Purchaser hereunder or with the Company’s prior written consent; and

(b) To deliver promptly to the Company at any time the Company may request, all memoranda, notices, records, reports and other documents (and all copies thereof) relating to the business of the Company or any of its affiliates including, but not limited to, Confidential Matters, which he may then possess or have under his control.

Notwithstanding any of the foregoing, the term “Confidential Matters” does not include information which is or becomes generally available to the public other than as a result of any disclosure by Xxxxx. Further, the obligations of confidentiality contained herein shall not apply to the extent that Xxxxx is compelled to disclose such Confidential Matters by judicial or administrative process; provided, however, that in the case of any such requirement or purported requirement Xxxxx shall provide written notice to the Company prior to producing such information, which notice shall be given at least ten (10) days prior to producing such information, if practicable, so that the Company may seek a protective order or other appropriate remedy.

6.2 Non-Competition Agreement. Xxxxx acknowledges that concurrent with the execution hereof, he will enter into a Non-Competition Agreement (the “Non-Competition Agreement”) which will contain similar confidentiality provisions and certain restrictive covenants prohibiting Xxxxx from engaging in certain competitive activities (including, without limitation, solicitation of employees and customers). A breach of the Non-Competition Agreement shall be deemed a breach of this Agreement. The Company and Xxxxx acknowledge and agree that the employment or solicitation of employees prohibited under the Non-Competition Agreement during the restriction period contained in the Non-Competition

Agreement is prima facie evidence that Xxxxx is using Confidential Matters in violation of Section 6.1 and the burden of proof in any proceeding to restrict such activity shall be on Xxxxx to provide such activity did not result in the unauthorized use of the Confidential Matters.

Notwithstanding the foregoing, Xxxxx may undertake or engage in any activities with any business solely to the extent that Xxxxx and/or such other business or person are not involved in any Restricted Activities in the Restricted Area, and Xxxxx may purchase or otherwise acquire up to (but not more than) one percent (1%) of any class of securities of any enterprise (but without other participation in the activities of such enterprise) if such securities are listed on any national or regional securities exchange or have been registered under Section 12(g) of the Securities Exchange Act of 1934, as amended. Xxxxx agrees that this covenant is reasonable with respect to its duration, geographical area and scope of activity to be restrained.

(ii) Xxxxx shall not, directly or indirectly, either for himself or any other person, (A) induce or attempt to induce any employee of Purchaser (or any subsidiary or affiliate of Purchaser) to leave the employ of Purchaser or such

subsidiary or affiliate, (B) in any way interfere with the relationship between Purchaser (or any subsidiary or affiliate) and any of its employees or (C) employ, or otherwise engage as an employee, independent contractor or otherwise, any then-current or past employees of Purchaser (or any subsidiary or affiliate) for the purposes of assisting or permitting such person to engage in any of the Restricted Activities in the Restricted Area unless such person shall have ceased to be employed by such entity and such cessation of employment shall have occurred at least twelve (12) months prior thereto.

(iii) Xxxxx shall not, directly or indirectly, either for himself or any other person, induce or attempt to induce any customer, supplier, licensee or business relation of Purchaser to cease doing business with Purchaser or in any way interfere with the relationship between any customer, supplier, licensee or business relation and Purchaser. Without limiting the generality of any of the restrictions contained in Section 5, Xxxxx shall not, directly or indirectly, either for himself or any other person, solicit the business of any person known to Xxxxx to be a customer or prospective customer of Purchaser with respect to products, services or activities which compete in whole or in part with any of the Restricted Activities of Purchaser within the Restricted Area; provided, however, that this prohibition shall not apply to general advertisements in newspapers or other widely distributed publications, media or mail, whether electronic or otherwise not targeted toward a specific customer.

(b) In the event of a breach by Xxxxx of any covenant set forth in Section 5(a), the term of such covenant will be extended by the period of the duration of such breach.

(c) Xxxxx agrees that he will not, at any time during or after the Restriction Period, disparage Purchaser or any of its subsidiaries, affiliates, shareholders, members, directors, managers, officers, employees, agents or other representatives of Purchaser or its subsidiaries or affiliates.

6. Remedies. If Xxxxx breaches the covenants set forth in Sections 4 or 5, Purchaser shall be entitled to the following remedies, in addition to any others, each of which shall be independent of the other and severally enforceable:

(a) The right and remedy to seek a temporary restraining order or preliminary injunctive relief and to have such provisions specifically enforced by any court having equity jurisdiction. Xxxxx specifically acknowledges and agrees that any breach or any affirmative acts which are reasonably believed to be a threatened breach of the provisions of Section 4 or 5 will cause irreparable injury to Purchaser and/or its subsidiaries and affiliates and that money damages will not provide an adequate remedy to Purchaser and/or its subsidiaries and affiliates. Such injunction shall be available without the posting of any bond or other security. If Xxxxx is determined to have breached any provision of Section 4 or 5, the court or arbitrator(s) shall extend the effect of the applicable provision of Section 5 for an amount of time equal to the time Xxxxx was in breach of Section 4 or 5.

(b) The right to require Xxxxx to account for and pay over to Purchaser and its subsidiaries and affiliates all compensation, profits, monies, accruals, increments or other benefits (hereinafter collectively the “Benefits”) derived or received by Xxxxx as a result of any transactions constituting a breach of any of the provisions of Section 4 or 5.

(c) Upon discovery by Purchaser of a breach or any affirmative acts which are reasonably believed to be a threatened breach of Section 4 or 5, the right to immediately suspend payments to Xxxxx under the Employment Agreement, pending a resolution of the dispute.

(d) The right to terminate Xxxxx’x employment for “Cause” pursuant to the Employment Agreement.

If, notwithstanding the stated and clear intent of the parties set forth in Sections 2, 4 and 5 above and their acknowledgement of the appropriateness of restrictions with respect to the duration, geography and activities set forth therein, any covenant contained in Section 5 or any portion thereof is hereafter construed to be invalid or unenforceable, the same shall not affect the remainder of the covenant or covenants contained therein, which shall be given full effect, without regard to the invalid portions, and any court having jurisdiction shall have the power to reduce the duration and/or area of such covenant and, in its reduced form, said covenant shall then be enforceable. The parties hereto intend to and hereby confer jurisdiction to issue temporary orders or preliminary injunctions to enforce the covenants contained in this Section 5 upon the courts of any state or other jurisdiction in which any alleged breach of any such covenant occurs, pending a ruling on a permanent injunction by the courts. If the courts of any of one or more of such states or other jurisdictions shall hold such covenants not wholly enforceable by reason of the scope thereof or otherwise, it is the intention of the parties hereto that such determination shall not be deemed to be res judicata or collateral estoppel or bar in any way Purchaser’s right to the relief provided above in the courts of any other states or jurisdictions as to breaches of such covenants in such other respective states or jurisdictions, and the above covenants as they relate to each state or jurisdiction being, for this purpose, severable into diverse and independent covenants.

7. Miscellaneous.

(a) Entire Agreement. This Agreement constitutes the entire agreement of the parties regarding the subject matter of this Agreement, and supersedes all prior or contemporaneous understandings among them with respect to the subject matter hereof.

(b) Severability. Whenever possible each provision and term of this Agreement will be interpreted in a manner to be effective and valid but if any provision or term of this Agreement is held to be prohibited by law or invalid, then such provision or term will be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provision or term or the remaining provisions or terms of this Agreement. If any covenants or any portion thereof set forth in this Agreement is held by a court of competent jurisdiction to contain limitations as to duration, geographical area or scope of activity to be restrained that are not reasonable and impose a greater restraint than is necessary to protect the

goodwill or other business interests of Purchaser and its subsidiaries and affiliates, the same shall not affect the remainder of the covenant or covenants contained therein, which shall be given full effect, without regard to the invalid portions, and any court having jurisdiction shall reform the covenants to the extent necessary to cause the limitations contained therein as to duration, geographical area and scope of activity to be restrained to be reasonable and to impose a restraint that is not greater than necessary to protect the goodwill or other business interests of Purchaser and it subsidiaries and affiliates and enforce the covenants as reformed.

(c) Successors and Assigns. This Agreement shall be binding upon Purchaser and Xxxxx and shall inure to the benefit of, and be enforceable by, Purchaser and its affiliates, successors and assigns and Xxxxx and his assigns, heirs and legal representatives.

(d) Governing Law. This agreement shall be governed by the laws of the State of Texas.

(e) Remedies Cumulative; Waiver. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power, or privilege under this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable law, (a) no claim or right arising out of this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other party; (b) no wavier that may be given by a party will be applicable except to the specific instance for which it is given and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement.

(f) Enforcement; Jurisdiction; Service of Process. If any legal action or other proceeding, including arbitration, is brought for the enforcement of this Agreement, or because of an alleged dispute, breach, default or misrepresentation in connection with any provisions of this Agreement, the prevailing party or parties shall be entitled to recover reasonable attorneys’ fees, court costs and all expenses even if not taxable as court costs, incurred in that action or proceeding, in addition to any other relief to which such party or parties may be entitled. The parties hereto intend to and hereby confer jurisdiction to enforce the covenants contained in this Agreement upon the courts of any state or other jurisdiction in which any alleged breach of such covenant occurs. If the courts of any one or more of such states or other jurisdictions hold that such covenants are not wholly enforceable by reason of the breadth of such scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect Purchaser’s or its subsidiaries’ and affiliates’ right to the relief provided above in the courts of any other states or jurisdictions within the geographical scope of such covenants, as to breaches of such covenants in such other respective states or jurisdictions. The above covenants as they relate to each state or jurisdiction are severable into diverse and independent covenants.

(g) Notices. Any notice or other communications required or permitted hereunder shall be in writing and, unless otherwise provided herein, shall be deemed to have been duly given upon delivery in person, by telecopy, by overnight courier or by certified or registered mail, return receipt requested, as follows:
