PURCHASE AND SALE AGREEMENT

THIS PURCHASE AND SALE AGREEMENT, dated as of July 19, 2011 (this “Agreement”), is by and among Rowan Companies, Inc., a Delaware corporation (the “Seller”), Ensign United States Drilling (S.W.) Inc., a Colorado corporation (the “Buyer”) and Ensign Energy Services Inc., an Alberta corporation (the “Parent Guarantor”). The Seller, the Buyer and the Parent Guarantor are hereinafter together referred to as the “parties” and each individually as a “party.”

WHEREAS, the Seller, through its wholly owned subsidiary Rowan Drilling Company LLC, a Delaware limited liability company (the “Company”), is engaged in the business of owning and operating a land rig fleet consisting of 31 land rigs, listed in Section 2.4(b) of the Seller Disclosure Letter (collectively, the “Rigs”), and provides drilling equipment and personnel on a contract basis for the Seller’s onshore contract drilling business (as conducted as of the date of this Agreement, the “Company Business”);

WHEREAS, prior to the date of this Agreement, the Company was converted from a corporation into a limited liability company, and all of the shares of common stock of the Company were converted into equity interests in such limited liability company (the “Membership Interests”);

WHEREAS, upon the terms and subject to the conditions set forth herein, the Seller desires to sell to the Buyer, and the Buyer desires to purchase from the Seller, all of the then issued and outstanding Membership Interests, of the Company; and

WHEREAS, Parent Guarantor desires to guarantee the obligations of the Buyer under this Agreement in accordance with Section 8.13.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound, the parties agree as follows:

ARTICLE 1

PURCHASE AND SALE

1.1 Purchase and Sale.

Upon the terms and subject to the conditions of this Agreement, at the Closing (as defined below):

(a) The Seller shall sell, convey, assign, transfer and deliver to the Buyer, and the Buyer shall purchase, acquire and accept from the Seller, the Membership Interests; and

(b) The Buyer shall pay to the Seller, in consideration for the Membership Interests, $510,000,000, (the “Purchase Price”), by wire transfer of immediately available funds to an account or accounts designated by the Seller prior to the Closing.

The transactions contemplated by this Section 1.1 are sometimes referred to in aggregate as the “Purchase.”

1.2 Conversion of the Company. Prior to the date of this Agreement, the Seller has caused the Company to be converted into a Delaware limited liability company in accordance with Delaware law, with all related documents and instruments to be in form and substance mutually satisfactory to the Seller and the Buyer in their respective reasonable judgments. Following the effectiveness of the conversion of the Company into a limited liability company and thereafter, neither the Seller nor any of its Affiliates has made or will make an election or take any action resulting in the Company being treated as anything other than an entity disregarded from its owner for United States federal and state income Tax purposes, and the Seller and its Affiliates will file all income Tax Returns in a manner consistent with such disregarded entity status. The parties agree that for United States federal and state income Tax purposes the purchase of the interests in a disregarded entity will be treated as a purchase of the assets of the Company.

1.3 Purchase Price Allocation. At least three business days before Closing, the Buyer shall provide to the Seller a schedule setting forth a proposal for an allocation of a portion of the Purchase Price (including any assumed liabilities) among the classes of company assets on IRS Form 8594 in accordance with Section 1060 of the Code and the U.S. Treasury Regulations promulgated thereunder (the “Purchase Price Allocation”). At the Closing, the parties shall mutually agree to the Purchase Price Allocation subject to any adjustments that may be required pursuant to Sections 1.10 and 4.14. Other than the adjustments pursuant to Sections 1.10 and 4.14, the Purchase Price Allocation agreed to at Closing shall be binding on the parties.

1.4 Time and Place of Closing. The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, at 9:00 a.m. (central time) on a date to be specified by the parties that shall be no later than two business days after satisfaction (or waiver as provided herein) of the conditions set forth in Article 5 (other than those conditions that by their nature will be satisfied at the Closing), unless another time, date and/or place is agreed to in writing by the parties. The date on which the Closing occurs is referred to as the “Closing Date.” Immediately upon consummation of the Closing, the Buyer shall take title to and ownership of the Membership Interests.

1.5 Deliveries by the Seller. Upon the terms and subject to the conditions of this Agreement, at the Closing, the Seller shall deliver (or cause to be delivered) the following to the Buyer:

(a) Original certificates for the Membership Interests, along with duly executed powers by the Seller in favor of the Buyer transferring the Membership Interests to the Buyer;

(b) The resignations (or evidence of the removal) of all members of the Board of managers of the Company, and the officers as set forth in Section 1.5(b) of the Seller Disclosure Letter;

(c) A certificate executed on the behalf of the Seller by an officer thereof, certifying as to the fulfillment of the conditions set forth in Sections 5.3(a) and 5.3(b);

(d) A Transition Services Agreement with the terms as provided in Section 4.3(f) (the “Transition Services Agreement”) in form and substance reasonably acceptable to the Buyer and the Seller;

(e) A certificate of non-foreign status, in form and substance reasonably acceptable to the Buyer and in the form provided in U.S. Treasury Regulation Section 1.1445-2(b)(2), issued pursuant to and in compliance with (including the making of any required filings with the IRS) U.S. Treasury Regulation Section 1.1445-2(b)(2), certifying that the Seller is not a foreign person within the meaning of U.S. Treasury Regulation Section 1.1445-2(b)(2);

(f) Evidence of the release of the Company as a guarantor under the Credit Agreement dated September 16, 2010 as amended on June 30, 2011, among Rowan Companies, Inc., as Borrower, the Lenders named therein, ▇▇▇▇▇ Fargo Bank, National Association, as Administrative Agent, Issuing Lender and Swingline Lender and Citibank, N.A., DnB Nor Bank ASA and Royal Bank of Canada, as Co-Syndication Agents; and

(g) All other documents, instruments and writings required to be delivered by the Seller at or (to the extent not previously delivered) prior to the Closing under this Agreement.

1.6 Deliveries by the Buyer. Upon the terms and subject to the conditions of this Agreement, at the Closing, the Buyer shall deliver (or cause to be delivered) the following to the Seller:

(a) The Purchase Price in immediately available funds as set forth in Section 1.1;

(b) A certificate executed on behalf of the Buyer by an officer thereof, certifying as to the fulfillment of the conditions set forth in Sections 5.2(a) and 5.2(b);

(d) An IRS Form 8594 setting forth the Purchase Price Allocation; and

(e) All other documents, instruments and writings required to be delivered by the Buyer at or (to the extent not previously delivered) prior to the Closing under this Agreement.

1.7 Intellectual Property; Marks. The Buyer agrees that it shall not acquire, nor shall the Company acquire or retain, any rights to the name “Rowan” (or any variation thereof) or any trademarks, trade names or symbols related thereto except as specifically contemplated in this Section 1.7. The Buyer shall as soon as reasonably practicable after Closing, and in any event within 30 days after the Closing, (i) at its own cost remove “Rowan” or any derivative, extension, abbreviation, variation or indicia thereof or other similar ▇▇▇▇ and any trade names, trademarks, identifying logos, service marks or symbols related thereto or employing the word “Rowan” or any part or variation of any of the foregoing or any confusingly similar trade names, trademarks, logos, service marks or symbols (collectively, the “Seller Trademarks and Logos”) from all Rigs and other properties and assets of the Company, (ii) cease, and not permit any of the Buyer’s Affiliates (including the Company), to use any of the Seller Trademarks and Logos, including in electronic databases, web sites, product instructions or specifications, technical documentation, datasheets, brochures, advertising, promotional and other marketing materials, invoices, letterhead, office forms and business cards, packaging and other materials, printed or otherwise (all such materials, together with buildings, signs, other properties and vehicles, the “Marked Assets”), and (iii) remove “Rowan” from the Company’s company name and registration in accordance with applicable Law. In addition, effective as of the Closing or within five business days thereafter, the Buyer shall amend the constitutional and/or organizational documents of the Company to remove all references therein to the name “Rowan” and to the address of the Seller or any of its Affiliates. As used in the Agreement, “Affiliate” means, with respect to any specified person, any other person that, directly or indirectly, controls, is under common control with, or is controlled by, such specified person, where the term “control” means, with respect to any person, the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such person, whether through the ownership of voting securities, by contract or otherwise.

1.8 Books of Minutes. At or as soon as practicable after the Closing, the Seller shall deliver to the Buyer the limited liability company books of minutes of meetings of the governing body of the limited liability company and the corporate minute books of the Company prior to its conversion to a limited liability company as well as the equity transfer records of the Company. The Seller may retain copies of any such books of minutes delivered to the Buyer.

1.9 Intercompany Accounts and Agreements. Except as set forth in Section 1.9 of the Seller Disclosure Letter, at or prior to the Closing, all intercompany accounts, leases and other agreements between the Company, on the one hand, and the Seller or any of its Affiliates (other than the Company), on the other hand, shall have been canceled, paid or otherwise settled and terminated. Subject to Section 1.10, no adjustment shall be made to the Purchase Price as a result of any such cancellations.

1.10 Distributions; Purchase Price Adjustment.

(a) The Purchase Price presumes that there is no Company Net Working Capital on the Closing Date. To the extent that Company Net Working Capital exists, the Purchase Price will be adjusted upwards or downwards, as appropriate in accordance with this Section 1.10. Additionally, the parties agree that the Seller shall have the right, at or prior to the Closing, to cause the Company to distribute some or all of the Company’s cash and working capital to the Seller by one or more dividends.

(b) Within 60 calendar days following the Closing, the Seller shall prepare, or cause to be prepared, and deliver to the Buyer a schedule of components of Company Net Working Capital as of the Closing Date (the “Closing Date Schedule”) and a statement (the “Closing Statement”) reflecting the calculation of any adjustment to the Purchase Price under Section 1.10(d), accompanied by a certificate of the Chief Financial Officer of the Seller to the effect that such statement has, to his or her knowledge, been prepared in accordance with the terms of this Agreement. As used in this Agreement, the “Company Net Working Capital” means the current assets of the Company minus the current liabilities of the Company, as such terms are customarily referred to under generally accepted accounting principles in the United States (“GAAP”) as consistently applied by the Company and the Seller, consistent with and subject in each case to the Working Capital Methodology; provided, however, that Company Net Working Capital shall not include income Taxes payable, income Taxes receivable or deferred income Taxes, liabilities relating to pension and post retirement obligations, and amounts included in Section 1.9, to the extent that the same remain the obligations of the Seller. For the avoidance of doubt, the parties agree that Section 1.10(b) of the Seller Disclosure Letter sets forth the calculation of Company Net Working Capital as of December 31, 2010. The Company Net Working Capital as of the Closing Date shall be prepared using the same methodology, assumptions, adjustments, estimates, and accounting policies and principles that were used to calculate the Company Net Working Capital as of December 31, 2010 (collectively, the “Working Capital Methodology”). The respective amounts included for any accounts, reserves or accruals that were determined by estimates in the calculation of Company Net Working Capital as of December 31, 2010 shall not be changed for the calculation of Company Net Working Capital as of the Closing Date, except to reflect circumstances or events occurring after December 31, 2010 consistent with the Working Capital Methodology. All determinations of Company Net Working Capital shall be made disregarding the effect of any accounting or tax elections or adjustments made at or subsequent to the Closing.

(c) The Buyer shall have a period of 30 calendar days after delivery of the Closing Date Schedule and the Closing Statement to review such documents and make any objections it may have in writing to the Seller. If such written objections are delivered to the Seller by the Buyer within such 30-day period, then the Buyer and the Seller shall attempt to resolve the matter or matters in dispute and a revised Closing Date Schedule and Closing Statement shall be prepared in accordance with such discussions. If no written objections are made by the Buyer within such 30-day period, then such Closing Date Schedule and Closing Statement shall be final and binding on the parties. If disputes with respect to such Closing Date Schedule or such Closing Statement cannot be resolved by the Buyer and the Seller within 30 calendar days after timely delivery of any objections thereto, then, at the request of the Seller or the Buyer, the specific matters in dispute shall be submitted to KPMG LLP or such other independent accounting firm as may be approved by the Buyer and the Seller (the “Auditors”), which firm shall render its opinion as to such specific matters. The Auditors shall promptly render their opinion only as to the specific matters so referred to them, and shall promptly send to the Buyer and the Seller such opinion and, based on such opinion, the Auditors’ determination of the specified matters in dispute, which determination shall be final and binding on the parties hereto. The fees and expenses of the Auditors shall be borne one-half by the Seller and one-half by the Buyer.

(d) If the Company Net Working Capital reflected on the Closing Date Schedule as finally determined under Section 1.10(b) is less than zero, then within five days following the final determination thereof, the Seller shall pay to the Buyer by wire transfer in immediately available funds to the account or accounts designated by the Buyer the amount of such deficiency, plus interest thereon at 5.00% per annum from (and including) the Closing Date to (but excluding) the date of such payment. If the Company Net Working Capital reflected on such Closing Date Schedule is greater than zero, then within five days following the final determination thereof, the Buyer shall pay to the Seller by wire transfer in immediately available funds to the account or accounts designated by the Seller the amount of such excess, plus interest thereon at such rate from (and including) the Closing Date to (but excluding) the date of such payment.

True and complete copies of the Organizational Documents of the Company have been provided to the Buyer. The Company is not in violation or default under any of its Organizational Documents.

There are no outstanding options, warrants, or other rights relating to the sale or voting of the Membership Interests that have been granted or entered into by the Seller or the Company, respectively.

(e) Notwithstanding anything to the contrary in this Agreement, except as set forth in Section 4.3(a) with respect to antitrust approvals, (i) neither the Seller or the Company on the one hand or the Buyer and its Affiliates on the other hand shall be required to take any action in connection with satisfying its obligations to obtain consents if such actions would require such Person to make any material payments or suffer any material burden on such Person in order to obtain any consent; and (ii) without the prior written consent of the Buyer, neither the Seller nor the Company will, in seeking to obtain any such consents, agree to amend, modify, terminate or waive any rights under the applicable contracts to which such consents relate or otherwise require the Company to make any payments or suffer any burden in connection therewith.

(f) The parties acknowledge that prior to the Closing Date, the Seller or its Affiliates has or will furnish certain administrative, management, accounting and operational services to the Company Business. Such services shall be terminated as of the Closing Date, except that, at the Buyer’s option, the Seller or its Affiliates shall continue some or all of such services for up to 90 days after the Closing Date under the Transition Services Agreement with customary terms, and providing for the Buyer to reimburse the Seller for such services beginning immediately after the Closing at the Seller’s actual cost plus ten percent and providing for the Seller to ▇▇▇▇ the Buyer for such services promptly following the end of each month during which such services are rendered.

4.4 Notification. Between the date of this Agreement and the Closing, each party shall promptly notify the other parties hereto in writing if such party becomes aware of any fact or condition that causes or constitutes a material breach of any of its representations and warranties as of the date of this Agreement, or if such party becomes aware of the occurrence after the date of this Agreement of any fact or condition that would (except as expressly contemplated by this Agreement) cause or constitute a material breach of any such representation or warranty of such party had such representation or warranty been made as of the time of occurrence or discovery of such fact or condition; provided, however, that such disclosure shall not be deemed to cure any material breach of a representation or warranty. During the same period, each party to this Agreement will promptly notify the other parties hereto of the occurrence of any material breach of any covenant or agreement by such party in this Agreement or of the occurrence of any event that may make the satisfaction of the conditions in Article 5 impossible or unlikely; provided, however, that such disclosure shall not be deemed to cure any material breach of a covenant or agreement or to satisfy a condition. Each party to this Agreement shall promptly notify the other parties of the threat or commencement of any Legal Proceeding before the Closing that could in any way affect the ability of such party to consummate the transaction.

4.5 No Negotiation. From the date of this Agreement through the earlier of the Closing Date or the date on which this Agreement is earlier terminated, neither Seller nor any of its Subsidiaries, Affiliates or Representatives shall, directly or indirectly, solicit, initiate or encourage any inquiries or proposals from, discuss or negotiate with, provide any information to or consider any inquiries or proposals from, any Person (other than the Buyer and its Affiliates and representatives) relating to any transaction involving the sale of all or any portion of the Company Business, whether affected by sale of assets, sale of equity interests, merger or otherwise. The Seller shall (i) ensure that its subsidiaries, Affiliates and representatives are aware of the provisions of this Section 4.5, and (ii) be responsible for any breaches by any such parties of this Section 4.5. At or prior to Closing, the Seller shall request and require the return or destruction of all confidential information concerning the Company Business or the Company made available to any third party (other than the Buyer and its Affiliates and Representatives) since January 1, 2010 with respect to or in connection with any inquiries, proposals or access to information prior to the Closing Date and of a type described in the first sentence of this Section 4.5 to the full extent provided in the confidentiality agreement entered into between the Seller and/or the Company and such third party in connection therewith. In addition, the Seller shall not release any such third party from any such confidentiality agreement (or any obligation thereunder) or waive, amend or alter any of such third party’s obligations thereunder and, at the reasonable request and expense of the Buyer enforce the terms of such confidentiality agreement against such third party and assign to the Buyer (to the extent assignable without the consent of such third party) the Seller’s rights thereunder as it relates to the Company Business and the Company. Nothing in this Agreement shall restrict or limit the Seller’s rights to engage in any discussions with respect to the Seller or any of its subsidiaries, assets or businesses, other than the Company.

4.6 Commercially Reasonable Efforts. Each of the Seller and the Buyer shall cooperate, and use its commercially reasonable efforts, to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate the transactions contemplated by this Agreement.

4.7 Public Announcements. Prior to but not after the Closing, except as set forth herein or otherwise agreed to by the parties, the parties shall not issue any report, statement or press release or otherwise make any public statements with respect to this Agreement or the transactions contemplated by this Agreement, except as in the reasonable judgment of the party may be required by Law or in connection with its or any of its Affiliate’s obligations as a publicly-held, exchange-listed company, in which case the parties shall take all reasonable measures to consult with each other as to the language of any such report, statement or press release.

4.8 Tax Matters.

(a) Indemnification.

(i) The Seller shall indemnify the Buyer from, against and in respect of any Taxes imposed on the Company with respect to any taxable period, or portion thereof, ending on or before the Closing Date, but not including (A) any Transfer Taxes or ad valorem Taxes for which the Buyer is liable under Section 4.8(e), and (B) any Taxes that were taken into account in determining the Company Net Working Capital under Section 1.10(b).

(ii) The Buyer shall indemnify the Seller from, against and in respect of any liability of the Seller for (A) any Taxes imposed on the Company with respect to any taxable period, or portion thereof, beginning after the Closing Date, (B) any liability of the Seller or its subsidiaries for any Transfer Taxes or ad valorem Taxes for which the Buyer is liable under Section 4.8(e) and (C) any Taxes that were taken into account in determining the Company Net Working Capital under Section 1.10(b).

(iii) Each of the Seller and the Buyer agrees to treat any indemnity payment made pursuant to this Agreement as an adjustment to the Purchase Price for all Tax purposes, unless otherwise required by applicable Laws.

(b) Allocation of Taxes. To the extent permitted by Law or administrative practice, the taxable years of the Company shall end at the close of business on the Closing Date. Whenever it is necessary to determine the liability for Taxes of the Company for a portion of a taxable year or period that begins before and ends after the Closing Date, the determination of the Taxes for the portion of the year or period ending on, and the portion of the year or period beginning after, the Closing Date shall be determined by assuming that the taxable year or period ended at the close of business on the Closing Date, except that exemptions, allowances or deductions that are calculated on an annual basis and Taxes imposed on the ownership, use or operation of real or personal property shall be prorated on the basis of the number of days in the annual period elapsed through the Closing Date as compared to the number of days in the annual period elapsing after the Closing Date.

(i) The Seller shall prepare, or cause to be prepared, and file or cause to be filed when due Tax Returns with respect to the Company for any taxable period ending on or before the Closing Date.

(ii) The Buyer shall prepare, or cause to be prepared, and file or cause to be filed when due all other Tax Returns with respect to the Company.

(iii) The Buyer shall provide the Seller with copies of all Tax Returns filed, or caused to be filed, by the Buyer with respect to the Company for periods beginning on or before the Closing Date and ending after the Closing, and the Seller shall provide the Buyer with copies of all Tax Returns filed, or caused to be filed, after the Closing Date by the Seller with respect to the Company.

(iv) The other party (the “Payor”) shall have the option of providing to the party responsible under this Agreement for filing such return (the “Preparer”), at any time at least 15 days prior to the Due Date, written instructions as to how the Payor wants any, or all, of the items for which it may be liable reflected on such Tax Return. The Preparer shall, in preparing such return, cause the items for which the Payor is liable under this Agreement to be reflected in accordance with the Payor’s instructions (unless, in the opinion of a partner of an internationally recognized law or accounting firm retained by the Preparer, complying with the Payor’s instructions would likely subject the Preparer to any civil or criminal penalty on any such item) and, in the absence of having received such instructions, in accordance with past practice. The Payor shall pay to the Preparer the amount of the Taxes with respect to such Tax Return for which the Payor is liable not later than 30 days after such Tax Return is filed.

(v) If the Preparer fails to satisfy its obligations under this Section 4.8(c), the Payor shall have no obligation to indemnify the Preparer for any incremental Taxes that are reflected on any such Tax Return as a result of such failure or any related Loss, and shall retain any and all remedies it may otherwise have that arise out of such failure.

(d) Tax Contests. The Buyer shall inform the Seller of the commencement of any audit, examination or proceeding (“Tax Contest”) relating in whole or in part to Taxes for which the Buyer may be entitled to indemnity from the Seller hereunder. With respect to any Tax Contest for which the Seller acknowledges in writing that the Seller is liable under Section 4.8(a) for all losses relating thereto, the Seller shall be entitled to control, in good faith, all proceedings taken in connection with such Tax Contest with counsel reasonably satisfactory to the Buyer; provided, however, that (x) the Seller shall promptly notify the Buyer in writing of the Seller’s intention to control such Tax Contest, (y) in the case of a Tax Contest relating to Taxes of the Company for a Tax period beginning before and ending after the Closing Date, the Buyer shall control all proceedings taken in connection with any such Tax Contest, and (z) if any Tax Contest could reasonably be expected to have an adverse effect on the Seller or the Company, in any Tax period ending on or before the Closing Date, the Tax Contest shall not be settled or resolved without the Seller’s consent, which consent shall not be unreasonably withheld or delayed. The Buyer and the Company shall use commercially reasonable efforts to provide the Seller with such assistance as may be reasonably requested by the Seller in connection with a Tax Contest controlled solely by the Seller.

(e) Transfer Taxes. All excise, sales, use, value added, transfer (including real property transfer or gains), stamp, documentary, filing, recordation and other similar taxes, levies, assessments, customs, duties, imposts, charges or fees, together with any interest, additions or penalties with respect thereto and any interest in respect of such additions or penalties, resulting directly from the sale and transfer by the Seller to the Buyer of the Membership Interests (the “Transfer Taxes”) shall be borne fully by the Buyer. Without limiting or altering the Buyer’s sole responsibility to pay all Transfer Taxes, the Buyer and the Seller agree to cooperate in (i) determining the amount of Transfer Taxes; (ii) providing all requisite exemption certificates; and (iii) preparing and timely filing any and all required Tax Returns for or with respect to such Transfer Taxes with any and all Governmental Entities.

(f) Income Tax Treatment of Transaction

. Prior to the Closing, the Company will become a disregarded entity for United States federal income Tax purposes and relevant state income Tax purposes. Accordingly, the parties intend that for United States federal income Tax purposes and for state income Tax purposes, (i) the Company will be treated as completely liquidating in a nontaxable transaction pursuant to Sections 332 and 337 of the Code, (ii) the purchase and sale hereunder of the Membership Interest in the Company as a single-member limited liability company will be treated as a taxable sale by the Seller of the assets of the Company to the Buyer, and a purchase of such assets by the Buyer from the Seller, for the Purchase Price and the assumption of liabilities of the Company, and (iii) the Company shall have completed a plan of complete liquidation of the Company for United States federal income Tax purposes pursuant to Section 332 of the Code. The parties agree not to take any position inconsistent with such intended Tax consequences, including any action that would cause the Company (as a limited liability company) to become taxable as a corporation or to reincorporate.

(g) Buyer’s Claiming, Receiving or Using of Refunds, Overpayments and Prepayments. If, after the Closing, the Buyer or the Company (A) receives any refund (whether by payment, offset, credit or otherwise) or (B) utilizes the benefit of any overpayment of Taxes that, in each case (A) and (B), (x) relates to Taxes for which the Seller is liable or paid by the Seller or the Company with respect to a taxable period, or portion thereof, ending on or before the Closing Date or (y) is the subject of indemnification by the Seller under this Agreement, the Buyer shall promptly transfer, or cause to be transferred, to the Seller the entire amount of the refund or overpayment (including interest) received or utilized by the Buyer or the Company. For purposes of the immediately preceding sentence, a prepayment made by the Seller or the Company on or before the Closing Date of Taxes for which the Buyer is liable shall be treated in the same manner as an overpayment of Taxes for which the Seller is liable. The Buyer agrees to notify the Seller within 15 days following the discovery of a right to claim any such refund or overpayment and the receipt of any such refund or utilization of any such overpayment. The Buyer agrees to claim any such refund or to utilize any such overpayment as soon as possible and to furnish the Seller all information, records and assistance necessary to verify the amount of the refund or overpayment.

(h) Post-Closing Actions That Affect the Seller’s Liability for Taxes. None of the Buyer, the Company or any of their respective Affiliates shall take any action (including amending any Tax Return) on or after the Closing Date that could materially increase the Seller’s liability for Taxes (including any liability of the Seller to indemnify the Buyer for Taxes under this Agreement), without the prior written consent of the Seller. The Buyer shall not cause the Company to waive or extend any statute of limitations for Taxes without the prior written consent of the Seller.

(i) No Carryback of Tax Attributes. The Buyer shall elect to waive any right to carry back any net operating loss of the Company which arises in a Tax year or portion thereof beginning on or after the Closing Date to any Tax year and period ending on or before the Closing Date under Section 172(b)(3) of the Code and Treasury Regulation section 1.1502-21(b)(3)(ii)(B) (and any similar provision of state, local or foreign income Tax law).

(j) Assistance and Cooperation. The Buyer and the Seller agree that, after the Closing Date:

(i) The Buyer and the Seller shall assist (and cause its respective Affiliates to assist) the other party in preparing any Tax Returns that such other party is responsible for preparing and filing;

(ii) The Buyer and the Seller shall cooperate fully in preparing for any Tax Audits, or disputes with taxing authorities, relating to any Tax Returns or Taxes of the Company, including providing access to relevant books and records relating to Taxes at issue;

(iii) The Buyer and the Seller shall make available to each other and to any taxing authority as reasonably requested all relevant books and records relating to Taxes;

(iv) The Buyer and the Seller shall promptly furnish the other party with copies of all relevant correspondence received from any taxing authority in connection with any Tax Audit or information request relating to Taxes for which such other party may have an indemnification obligation under this Agreement; and

(v) Except as otherwise provided in this Agreement, the party requesting assistance or cooperation shall bear the other party’s out-of-pocket expenses in complying with such request to the extent that those expenses are attributable to fees and other costs of unaffiliated third-party service providers.

(k) This Section 4.8 contains the exclusive provisions as to all Tax indemnification claims. Article 7 shall not apply to Tax indemnification claims.

(l) For purposes of this Agreement, “Tax” or “Taxes” shall mean (i) taxes of any kind, levies or other like assessments, customs, duties, imposts, charges or fees, including income taxes, gross receipts, ad valorem, value added, excise, real or property, asset, sales, use, license, payroll, transaction, capital, net worth, withholding, estimated, social security, utility, workers’ compensation, severance, production, unemployment compensation, occupation, premium, windfall profits, transfer and gains taxes or other governmental taxes imposed or payable to the United States, or any state, county, local or foreign government or subdivision or agency thereof, together with any interest, penalties or additions with respect thereto and any interest in respect of such additions or penalties; (ii) any liability for payment of amounts described in clause (i) whether as a result of transferee liability, of being a member of an affiliated, consolidated, combined or unitary group for any period or otherwise through operation of law; and (iii) any liability for the payment of amounts described in clauses (i) or (ii) as a result of any tax sharing, tax indemnity or tax allocation agreement or any other express or implied agreement to indemnify any other Person with respect thereto; “Due Date” shall mean, with respect to any Tax Return, the date such return is due to be filed (taking into account any valid extensions); and “Tax Item” shall mean, with respect to Taxes, any item of income, gain, deduction, loss or credit or other tax attribute.

4.9 Buyer’s Knowledge of Breach. If, prior to the Closing, the Buyer shall have actual knowledge of any breach of a representation and warranty of the Seller, the Buyer shall promptly notify the Seller of the Buyer’s knowledge, in reasonable detail, including the amount that the Buyer believes, based on the facts actually known by it, would be payable by the Seller under the indemnification provisions of this Agreement without reference to any indemnification limitations set forth in Section 7.2 of this Agreement.

4.10 Employees; Employee Benefits.

(a) Offer of Employment. The Buyer hereby agrees that, prior to the Closing Date, an Affiliate of the Buyer will extend an offer of employment to not fewer than 95% of the Seller Assigned Employees in accordance with the terms of this Section 4.10. Any Seller Assigned Employee who receives an offer of employment from the Buyer’s Affiliate but does not accept such offer will not be eligible for any severance benefit under any Seller Benefit Plan. Any Seller Assigned Employee who accepts such offer of employment with the Buyer’s Affiliate is herein referred to as a “Transferring Employee.” All Transferring Employees’ service with the Seller or its Affiliates will be terminated by the Seller or its Affiliates as of the Closing Date.

At least five business days before the Closing, the Buyer shall furnish to the Seller a list of the names of any Seller Assigned Employees who will not receive an offer of employment from the Buyer’s Affiliate, and the Seller shall have the right, but not the obligation, to retain such employees. Any employees so retained are herein referred to as “Seller Retained Employees”. Notwithstanding the foregoing, the three employees listed on Section 4.10(a) of the Seller Disclosure Letter may remain as Seller Retained Employees if they so choose, in their sole discretion. The Seller will be responsible for any change of control payment due to any employee of the Seller (or one or more of the Seller’s Affiliates) in connection with this Agreement.

Any employee who is not given an offer of employment by the Buyer’s Affiliate and who is not a Seller Retained Employee will be terminated by the Seller on or before the Closing Date (“Terminated Employees”), and the Seller is obligated to pay any and all severance obligations under the seller severance plan (the “Seller Severance Plan”) for all such Terminated Employees.

The terms of any offer of employment by the Buyer’s Affiliate to a Seller Assigned Employee shall be at least at substantially the same base salary or hourly rate of pay, as applicable, and bonus opportunity, in each case as exists on the date of this Agreement, and such terms shall recognize each Seller Assigned Employee’s years of service, seniority and tenure with the Seller and its Affiliates prior to the Closing Date in all respects, including for purposes of terms of employment and eligibility, vesting, benefit accrual, and bonus determination.

Nothing contained in this Agreement shall affect the ability of Buyer’s Affiliate to alter the terms, conditions or wages of any Transferring Employee’s employment after a period of twelve months following the Closing Date; provided, however, that nothing in this paragraph shall limit the right of Buyer’s Affiliate at any time after the Closing Date to alter the terms, conditions or wages of such Transferring Employees, if consistent with the policies and procedures concerning the Buyer’s or its Affiliates’ other employees or to adjust such terms or conditions due to a downturn in the Company Business, the condition of the industry, the termination of customer contracts, or for any other valid business purpose, including but not limited to compliance with any federal immigration law or any applicable state law that penalizes a business that fails to use the federal EVerify system.

(b) Buyer Benefit Plans. From and after the Closing Date, the Transferring Employees shall be covered under employee compensation and benefit plans, policies, programs or arrangements as the Company, the Buyer or an Affiliate of the Buyer, shall make available (the “Buyer Benefit Plans”) in accordance with the requirements of Section 4.10(a). The Buyer shall cause the Buyer Benefit Plans, for purposes of determining a Transferring Employee’s eligibility to participate, vesting and eligibility for benefits, to recognize the service, seniority and tenure that is recognized by the Seller or its Affiliates immediately prior to the Closing Date. The Transferring Employees shall have substantially the same benefits as similarly situated employees of the Buyer or its Affiliates. The Buyer or its Affiliates shall cause there to be waived for such Transferring Employees any waiting periods and actively-at-work requirements to the extent necessary to provide immediate coverage under such plans. The Buyer, its Affiliates or the Company shall be solely responsible for all benefits accruing to the Transferring Employees under the Buyer Benefit Plans.

(c) Welfare Plans. The Seller or its Affiliates (other than the Company) shall be liable for claims for benefits (other than for short-term disability, workers’ compensation and medical benefits) by Transferring Employees under each welfare benefit plan sponsored by the Seller or its Affiliates (including, but not limited to, The Group Life & Health Insurance Plan of Parent Companies, Inc. (inclusive of its constituent plans)) arising out of occurrences on or prior to the Closing Date. The Seller or its Affiliates (other than the Company) shall be liable for claims for short-term disability benefits and workers’ compensation benefits by Transferring Employees under such welfare benefit plans with respect to payments otherwise due on or prior to the Closing Date. The Seller or its Affiliates (other than the Company) shall be liable for claims for medical benefits by Transferring Employees under such welfare benefit plans with respect to services and treatment rendered on or prior to the Closing Date. The Buyer or its Affiliates shall provide welfare benefit coverages for the Transferring Employees for which the Seller or its Affiliates are not otherwise liable. The Buyer or its Affiliates shall cause each of the Transferring Employees to be granted credit under its health benefit plans, for the year during which the Closing Date occurs, with any deductibles, co-insurance payments and out-of-pocket expenses already incurred by such Transferring Employees for such year under the plans of the Seller or its Affiliates, and the Buyer or its Affiliates shall cause there to be waived for such Transferring Employees any preexisting condition restrictions, evidence of insurability, exclusions, waiting periods and actively at-work requirements, under its health benefits plans to the extent necessary to provide immediate coverage under such plans after the Closing Date. The Buyer shall offer, or shall cause the Company or the Buyer’s Affiliate (as the case may be) to offer, continuation health care coverage to Transferring Employees after the Closing Date and their qualified beneficiaries who incur or incurred a qualifying event, in accordance with the continuation health care coverage requirements of Section 4980B of the Code and Title I, Subtitle B, Part 6 of ERISA (“COBRA”), after the Closing Date. The Seller shall be responsible for offering continuation health care coverage to Transferring Employees and their qualified beneficiaries who incur or incurred a qualifying event, in accordance with COBRA, on or before the Closing Date.

(d) Cessation of Participation in Seller Benefit Plans. Except as otherwise specifically provided in Section 4.10, from and after the Closing Date, the Transferring Employees will accrue no additional benefits under the Seller Benefit Plans. Notwithstanding the foregoing, the Seller shall retain benefit obligations under the Seller Benefit Plans to Transferring Employees as set forth in Section 4.10(d) of the Seller Disclosure Letter. Except as otherwise specifically provided in this Section 4.10(d), the Seller (or the applicable Seller Benefit Plan) shall discharge all obligations to Transferring Employees (including funding obligations) with respect to benefits accrued prior to the Closing Date under the Seller Benefit Plans, and neither the Buyer, its Affiliates nor the Company shall have any liability or responsibility therefor; provided that neither the Seller nor any of the Seller Benefit Plans will recognize for any purpose a Transferring Employee’s post-Closing employment with the Company, the Buyer or an Affiliate of the Buyer.

(e) Retiree Medical Benefits. The Seller, at the Seller’s cost, shall be responsible for the funding of the Retiree Life & Medical Supplement Plan of the Seller (the “Seller Retiree Medical Plan”) for the benefit of Seller Assigned Employees who are participants in the Seller Retiree Medical Plan and who are age fifty or older as of the Closing Date. The Buyer and its Affiliates (including the Company) shall have no liability whatsoever in connection with the Seller Retiree Medical Plan.

(f) Accumulated Vacation, Holiday and Sick Leave. The Seller shall be responsible for paying Transferring Employees for all accumulated paid time off days accrued or accumulated by the Transferring Employees but that are unused as of the Closing Date. The Seller shall pay Transferring Employees for all such accrued but unused paid time off days prior to the Closing Date.

(g) Pension Plan. The Seller, at the Seller’s cost and expense, shall take such action as is necessary, on or before the Closing Date, to cause each of the Transferring Employees to have a fully nonforfeitable right in such Transferring Employee’s accrued benefit under the Seller Pension Plan as of the Closing Date. The Buyer and its Affiliates (including the Company) shall have no liability whatsoever in connection with the Seller Pension Plan

(h) 401(k) Plan. The Seller shall take such action as is necessary, on or before the Closing Date, to cause each of the Transferring Employees to have a fully nonforfeitable right in his account balance under the Parent Savings & Investment Plan (“Seller’s 401(k) Plan”) as of the Closing Date. The Seller and its Affiliates represent, covenant and agree with respect to the Seller’s 401(k) Plan, that, as of the Closing Date such plan will satisfy the requirements of Sections 401(a), (k), and (m) of the Code and will not have been amended or operated in a way that would adversely affect such qualified status. The Buyer and its Affiliates (including the Company) will not receive any assets from the Seller’s 401(k) plan and will have no liability whatsoever with respect to such plan.

(i) No Rights or Amendment. The provisions of this Section 4.10 are for the benefit of the parties to this Agreement only and shall not be construed to grant any rights, as a third party beneficiary or otherwise, to any person who is not a party to this Agreement, nor shall any provision of this Agreement be deemed to be the adoption of, or an amendment to, any employee benefit plan sponsored or maintained by the Buyer and its Affiliates, or the Seller and its Affiliates, or otherwise to limit the right of the Buyer or the Seller to amend, modify or terminate any of their employee benefit plans.

4.11 Control of Other Party’s Business. Nothing contained in this Agreement shall give the Buyer, directly or indirectly, the right to control or direct the operation of the Company Business prior to Closing and each of the Buyer, the Seller and the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its respective operations prior to Closing.

4.12 Non-Competition.

(a) From the Closing Date until the fourth anniversary of the Closing Date (the “Restricted Period”), without the Buyer’s consent, the Seller shall not, and shall cause each of its Subsidiaries (the Seller and its Subsidiaries, the “Restricted Party”) not to, directly or indirectly (including by means of management, advisory, operating, or similar agreements or arrangements or by any record or beneficial equity interest, either as a principal, trustee, stockholder, partner, joint venture or otherwise, in any Person), engage in a land-based drilling business that competes with the Company Business, for their own account or for any other Person, in any state in which the Company operates the Company Business or otherwise had sales immediately prior to the Closing (the “Restricted Business”); provided, however, that nothing in this Agreement or in the definition of Restricted Business shall prohibit or in any way restrict the Restricted Party’s ability to:

(i) engage in the Restricted Business to the extent necessary to perform its duties under this Agreement;

(ii) make or maintain passive investments of less than five percent of the outstanding equity securities in any entity engaged in the Restricted Businesses listed for trading on any recognized securities exchange or in the over-the-counter markets; or

(iii) acquire the assets or capital stock or other equity interests of or enter into a merger, consolidation of business combination with any other Person engaged in the Restricted Business, provided, however, that the net sales attributable to the Restricted Business conducted by such Person account for less than 25% of the net sales of such Person for its most recently completed fiscal year.

(b) The parties agree that this covenant is personal to the Buyer, and the Buyer may not assign or otherwise transfer this covenant, in whole or in part, to any Person other than to other Affiliates of the Buyer. During the Restricted Period, the Seller shall not, and shall cause each of its Affiliates not to, without the prior written consent of the Buyer, directly or indirectly, induce or attempt to induce any customer, reseller, retailer, distributor, supplier, licensee or other Person to cease doing business with the Buyer or the Company or in any way interfere with the relationship between any such customer, reseller, retailer, distributor, supplier, licensee or other Person and the Buyer or the Company.

(c) The Seller agrees that any remedy at law for any breach by it or its Affiliates of Section 4.12(a) or Section 4.12(b) would be inadequate, and the Buyer shall be entitled to injunctive or other equitable relief in such case in addition to any other right the Buyer may have, whether at law or in equity. Each party intends that the provisions of this Section 4.12 be enforced under the laws applied in each jurisdiction in which enforcement is sought. If any provision of this Section 4.12 shall be held by a court of competent jurisdiction to be invalid or unenforceable, this Section 4.12 shall be amended to revise the scope of such provision to make it enforceable, if possible, or, if not possible, to delete such provision, in either case, without affecting the other or remaining provisions of this Section 4.12 or this Agreement. Any invalidity or unenforceability of any provision of this Section 4.12 in a jurisdiction will not affect the validity or enforceability of that provision in any other jurisdiction.

4.13 Non-Solicitation.

(a) For a period of 18 months from the date of this Agreement, the Seller shall not, and shall cause its Affiliates not to, directly or indirectly induce or attempt to induce any employee, any consultant or any independent contractor to discontinue work with the Buyer or in any way knowingly interfere with the relationship between the Buyer and any employee, consultant, independent contractor or person employed by the Buyer, nor shall the Seller contact, approach or solicit any such Persons for the purpose of hiring.

(b) For a period of 18 months from the date of this Agreement, the Buyer shall not, and shall cause its Affiliates not to, directly or indirectly induce or attempt to induce any employee, any consultant or any independent contractor to discontinue work with the Seller or in any way knowingly interfere with the relationship between the Seller and any employee, consultant, independent contractor or person employed by the Seller, nor shall the Buyer contact, approach or solicit any such Persons for the purpose of hiring.

(i) the foregoing provision shall not apply to any employee of the Buyer or the Seller or their respective Affiliates whose annual base compensation is less than $75,000, and

(ii) the foregoing provisions shall not prohibit (A) the hiring of a Person whose employment was terminated by his or her respective employer (or its Affiliates) and who was not solicited by the other party (or its Affiliates) in violation of Sections 4.13(a) or 4.12(b), as applicable, or (B) solicitation by way of general advertising, including general solicitations in any local, regional or national newspapers or other publications or circulars or on internet sites or any search firm engagement which is not directed or focused on employees of the Buyer, or the Seller or their respective Affiliates, as applicable.

(d) The parties agree that the restraints created by the covenants in this Section 4.13 are no greater than necessary to protect the parties’ respective legitimate interests, that damages would be an inadequate remedy and that a Person seeking to enforce this Section 4.13 shall be entitled to seek specific performance and injunctive relief as remedies for any breach hereof. Furthermore, the parties agree that such covenants do not hinder, or otherwise cause hardship to, any party or its Affiliates with respect to finding other employees or any party’s or its Affiliates’ employees with respect to finding employment elsewhere. Similarly, the parties agree that no party’s need for the protection afforded by the covenants of this Section 4.13 is outweighed by either the hardship to any other party or its Affiliates or any public interest. The existence of any claim or cause of action of a party against another party, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by a party of the covenants contained in this Section 4.13. Should any portion of the covenants in this Section 4.13 be held to be wholly or partially invalid or unenforceable because such portion is held to be overly broad or unreasonable in scope, such holding shall not invalidate or void the remainder of this Section 4.13 or this Agreement, and the portions held to be overly broad or unreasonable in scope shall be revised and reduced in scope so as to be valid and enforceable, and shall be enforced as so reformed, to the maximum extent permitted by law.

4.14 Casualty Loss.

(a) In the event of any fire, explosion, accident, earthquake, act of the public enemy, act of God, or other similar event or occurrence that results in damage to, the loss of or the destruction of any Rig or other material Company asset (a “Casualty Event”) that occurs between the date of execution hereof and the Closing Date and is not a Business Material Adverse Effect, the Seller shall give the Buyer prompt written notice of the Casualty Event together with a description of the applicable insurance coverage and an estimate of the Seller’s exposure with respect to such Casualty Event. The Seller shall have the first right and option to repair or replace the Rig or other material Company asset with items of equivalent quality and value, at the Seller’s sole cost and expense. If the Seller elects to repair the damage caused by the relevant Casualty Event or replace the Rig or other material Company asset damaged or taken, the Seller shall commence such repair or replacement as soon as reasonably practicable after the occurrence of such Casualty Event, promptly and diligently continue such efforts until such damaged or taken Rig or other material Company asset has been fully repaired or replaced with an item of comparable quality and value, and pay all costs and expenses incurred in connection therewith. If the Seller elects not to repair or replace the damaged or taken Rig or other material Company asset, or if the Seller is unable to repair or replace the damaged or taken Rig or other material Company asset on or before the Closing Date, the Buyer shall accept the affected Rig or other material Company asset subject to such unremedied Casualty Event, proceed to Closing, and receive a reduction in the Purchase Price equal to (i) the estimated cost to repair the Rig or other material Company asset, as agreed to by the parties in good faith (the “repair cost”), or, (ii) in the case of the loss of or destruction of a Rig or other material Company asset, the greater of the insured value or replacement value of such Rig or other material Company asset affected by such Casualty Event. If the Purchase Price is reduced as specified in this Section 4.14(a), the Seller shall be entitled to retain any and all insurance proceeds.

(b) For the avoidance of doubt, in no event shall any reduction in the Purchase Price be made for ordinary wear and tear occurring prior to the Closing. If the parties are unable to agree on repair costs within five Business Days prior to the Closing Date, the parties shall submit the issue to a recognized firm that is mutually acceptable to the parties (the “Appraiser”). The Seller and the Buyer shall each submit to the Appraiser their proposed repair costs together with support calculations and documentation with respect thereto. The Appraiser shall, prior to Closing, advise the parties as to its determination of the repair costs. The final value of such costs of recovery, salvage and repairs as determined in this Section 4.14(b) shall be the “repair costs” for purposes of this Section 4.14. The costs of retaining the Appraiser shall be borne equally by the Seller and the Buyer. For the avoidance of doubt, no such casualty loss or damage shall in any way be considered in the determination of a termination of this Agreement under Section 6.1 of this Agreement.

(c) by the Seller or the Buyer by giving written notice to the other party if the other party, has failed to perform its covenants or agreements contained herein required to be performed on or prior to the Closing Date or has breached any of its representations or warranties contained herein, in each case in clause (c) such that the related condition set forth in Article 5 would not be satisfied (assuming for this purpose that the references in Article 5 to “Closing Date” mean the date of termination pursuant to this Section 6.1); provided, however, that the defaulting party shall have a period of ten business days following written notice from the non-defaulting party to cure any breach of this Agreement, if such breach is curable; or

(d) by the Seller or the Buyer by giving written notice to the other party if there shall be any Legal Requirement that makes the transactions contemplated by this Agreement illegal or otherwise prohibited of if the consummation of these transactions contemplated by this Agreement would violate any non-appealable Order of any Governmental Entity having competent jurisdiction.

6.2 Procedure for and Effect of Termination.

(a) In the event of termination of this Agreement and abandonment of the transactions contemplated by this Agreement under Section 6.1, written notice thereof shall be given by a party so terminating to the other party and this Agreement shall forthwith terminate and shall become null and void and of no further effect, and the transactions contemplated by this Agreement shall be abandoned without further action by the Seller or the Buyer. If this Agreement is terminated under Section 6.1:

(i) the Buyer shall redeliver all documents and other materials of the Seller or any of its Affiliates relating to the transactions contemplated by this Agreement, whether obtained before or after the execution of this Agreement, to the Seller, and all confidential information received by the Buyer hereto with respect thereto shall be treated in accordance with the Confidentiality Agreement and Section 4.2(b);

(ii) all filings, applications and other submissions made pursuant hereto shall, at the option of the Seller, and to the extent practicable, be withdrawn from the agency or other person to which made; and

(iii) there shall be no liability or obligation under this Agreement on the part of the Seller or the Buyer or any of their respective directors, officers, employees, Affiliates, agents or representatives, except with respect to a breach of Section 3.5 of this Agreement by the Buyer and except that the Seller or the Buyer, as the case may be, may have liability to the other party if the basis of termination is a willful, material breach by the Seller or the Buyer, as the case may be, of one or more of the provisions of this Agreement, and except that the obligations provided for in Section 6.1(d), Section 8.4, Section 8.5, Section 8.8 and Section 8.13 of this Agreement shall survive any such termination.

(c) The parties acknowledge that the agreements contained in this Section 6.2 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the parties would not have entered into this Agreement.

ARTICLE 7

All representations and warranties of the parties contained in this Agreement shall survive the Closing and shall continue until the 18-month anniversary of the Closing Date but, except as provided in Section 6.2(a)(iii) of this Agreement, shall not survive any termination of this Agreement; provided that the representations and warranties set forth in Section 2.1 (Organization; Etc. of Seller), Section 2.2 (Authority of Seller), Section 2.3 (Capitalization), Section 2.4(b) (Ownership), Section 2.10 (Employee Benefit Plans), Section 2.14 (Environmental Matters), Section 3.1 (Organization; Etc. of Buyer), Section 3.2 (Authority of Buyer) (the “Fundamental Representations”) shall survive the Closing and shall continue until the 36-month anniversary of the Closing Date, all claims for breach of any other covenant shall survive until the 36-month anniversary of the Closing Date, the representations and warranties set forth in Section 2.13 (Taxes) and Section 4.8 (Tax Matters) shall survive until 60 days following the expiration of the applicable statute of limitations, and the representations and warranties set forth in Section 2.4(a) (Ownership) shall survive indefinitely. The covenants and agreements of the parties contained in this Agreement that by their terms contemplate performance after the Closing, including without limitation Sections 4.8 and 4.12, shall survive the Closing until 60 days following the date specified therein, or if no such date is specified, the expiration of the applicable statute of limitations for each such covenant and agreement. The applicable period set forth above in this Section 7.1 for each such representation, warranty, covenant and agreement is referred to herein as the “Survival Period.” The parties intend to modify the statute of limitations and agree that no claims or causes of action may be brought against the Seller or the Buyer based upon, directly or indirectly, any of the representations, warranties, covenants or agreements contained in this Agreement after the applicable Survival Period or, except as provided in Section 6.2(a)(iii) of this Agreement, any termination of this Agreement.

7.2 Seller’s Agreement to Indemnify.

(a) Upon the terms and subject to the conditions set forth in this Agreement, from and after the Closing, the Seller shall indemnify and hold harmless the Buyer and its directors, officers, employees, Affiliates, agents and representatives and their successors and assigns (collectively, the “Buyer Indemnitees”) from and against all liabilities, demands, claims, deficiencies, actions or causes of action, assessments, losses, damages, costs and expenses (including without limitation, interest, penalties, reasonable attorneys’ fees and expenses and all reasonable amounts paid in settlement of any of the foregoing) (collectively, “Buyer Damages”) asserted against or incurred by any Buyer Indemnitee to the extent arising out of or resulting from the following: (i) any breach of any representation or warranty of the Seller in this Agreement; (ii) any breach or nonfulfillment of any covenant, agreement or other obligation of the Seller in this Agreement; (iii) the matters listed in Section 7.2 of the Seller Disclosure Letter; (iv) any claim for brokerage or finder’s fees or commissions or similar payments based on any agreement or understanding alleged to have been made in connection with the Purchase; (v) any Seller Benefit Plans, including without limitation, the Seller Retiree Medical Plan, the Seller Pension Plan and the Seller Severance Plan; (vi) any Legal Proceeding or Order applicable to the Company as of the Closing Date, or (vii) any Indebtedness of the Company to the extent attributable to the operation of the Company or the Company Business prior to the Closing Date.

(b) The obligation of the Seller to indemnify the Buyer Indemnitees under Section 7.2 is subject to the following limitations:

(i) No indemnification shall be made by the Seller pursuant to clause (i) of Section 7.2(a) unless the aggregate amount of Buyer Damages subject to such clauses exceeds $750,000 (the “Threshold Amount”) and, in such event, indemnification shall be made by the Seller from the first dollar; provided, however, that any Buyer Damages that individually total less than $100,000 (“De Minimis Buyer Losses”) shall be excluded in their entirety for all purposes, including counting towards fulfillment of the Threshold Amount, and the Seller in no event shall have any liability hereunder to any Buyer Indemnitees for any such De Minimis Buyer Losses; and provided, further, that claims for Buyer Damages pursuant to Section 7.2(a) resulting from fraud or from a breach of the Fundamental Representations or the representations and warranties identified in Section 7.1(c) and Section 7.1(d) made by the Seller shall not be subject to the Threshold Amount, and shall be recoverable from the first dollar. This Section 7.2(b)(i) shall not apply to claims for indemnification made pursuant to clauses (ii), (iii), (iv), (v), (vi) and (vii) of Section 7.2(a).

(ii) In no event shall the Seller’s aggregate obligation to indemnify the Buyer Indemnitees pursuant to clause (i) of Section 7.2(a) exceed $40,000,000 in the aggregate, provided, however, that this limitation shall not apply to claims for Buyer Damages pursuant to Section 7.2(a) resulting from fraud or from a breach of the Fundamental Representations or the representations and warranties identified in Section 7.1(c) and Section 7.1(d) made by the Seller. This Section 7.2(b)(ii) shall not apply to claims for indemnification made pursuant to clauses (ii), (iii), (iv), (v), (vi) and (vii) of Section 7.2(a).

(iii) The amount of any Buyer Damages shall be reduced by any amount directly or indirectly received by a Buyer Indemnitee (including, for this purpose, the Company) with respect to such Buyer Damages under any insurance coverage or from any other party alleged to be responsible for such Buyer Damages less any expenses of recovery, deductibles and/or co-payment. The Buyer Indemnitees shall use commercially reasonable efforts to collect any amounts available under such insurance coverage and from such other party alleged to have responsibility. If a Buyer Indemnitee directly or indirectly receives any amount under insurance coverage or from such other party with respect to Buyer Damages at any time subsequent to any indemnification provided by, or for the benefit of, the Seller under this Section 7.2, then such Buyer Indemnitee shall promptly reimburse the Seller for any payment made or expense incurred by, or for the benefit of, the Seller in connection with providing such indemnification up to such amount received by such Buyer Indemnitee less any expenses of recovery, deductibles and/or co-payments.

(iv) The Seller shall be obligated to indemnify the Buyer Indemnitees only for those claims giving rise to Buyer Damages as to which the Buyer Indemnitees have given the Seller written notice thereof prior to the end of the applicable Survival Period. Any written notice delivered by a Buyer Indemnitee to the Seller with respect to Buyer Damages shall set forth with as much specificity as is reasonably practicable the basis of the claim for Buyer Damages and, to the extent reasonably practicable, a reasonable estimate of the amount of such claim.

(v) The Seller shall be entitled to control each of the matters and Legal Proceedings referenced in clause (iii) of Section 7.2(a), at the Seller’s expense.

Such cooperation shall include access to books, records and personnel. With respect to such matters and Legal Proceedings referenced in clause (iii) of Section 7.2(a), the Seller shall be entitled to all proceeds, if any, received by the Company with respect to such matters and Legal Proceedings, and the Buyer shall cause the Company to turn over promptly to the Seller all such proceeds.

7.3 Buyer’s Agreement to Indemnify.

(a) Upon the terms and subject to the conditions set forth in this Agreement, from and after the Closing, the Buyer shall indemnify and hold harmless the Seller and its directors, officers, employees, Affiliates, agents and representatives and their successors and assigns (collectively, the “Seller Indemnitees”) from and against all liabilities, demands, claims, deficiencies, actions or causes of action, assessments, losses, damages, costs and expenses (including without limitation interest, penalties, reasonable attorneys’ fees and expenses and all reasonable amounts paid in settlement of any of the foregoing) (collectively, “Seller Damages”) asserted against or incurred by any Seller Indemnitee to the extent arising out of or resulting from the following: (i) any breach of any representation or warranty of the Buyer in this Agreement; (ii) any breach or nonfulfillment of any covenant, agreement or other obligation of the Buyer in this Agreement; and (iii) the ownership or operation of the Company, the Company Business and the Rigs after Closing.

(b) The obligation of the Buyer to indemnify the Seller Indemnitees under Section 7.3 is subject to the following limitations:

(i) No indemnification shall be made by the Buyer pursuant to clause (i) of Section 7.3(a) unless the aggregate amount of Seller Damages subject to such clauses exceeds the Threshold Amount; provided, however, that any Seller Damages that individually total less than $100,000 (“De Minimis Seller Losses”) shall be excluded in their entirety for all purposes, including counting towards fulfillment of the Threshold Amount, and the Seller in no event shall have any liability hereunder to any Buyer Indemnitees for any such De Minimis Seller Losses; and provided, further, that claims for Seller Damages pursuant to Section 7.3(a) resulting from fraud or a breach of the Fundamental Representations made by the Buyer shall not be subject to the Threshold Amount, and shall be recoverable from the first dollar. This Section 7.3(b)(i) shall not apply to claims for indemnification made pursuant to clauses (ii) and (iii) of Section 7.3(a).

(ii) In no event shall the Buyer’s aggregate obligation to indemnify the Seller Indemnitees pursuant to clauses (i) of Section 7.3(a) exceed $40,000,000 in the aggregate provided, however, that this limitation shall not apply to claims for Seller Damages pursuant to Section 7.3(a) resulting from fraud or a breach of the Fundamental Representations made by the Buyer. This Section 7.3(b)(ii) shall not apply to claims for indemnification made pursuant to clauses (ii) and (iii) of Section 7.3(a).

(iii) The amount of any Seller Damages shall be reduced by any amount directly or indirectly received by a Seller Indemnitee with respect to such Seller Damages under any insurance coverage or from any other party alleged to be responsible for such Seller Damages less any expenses of recovery, deductibles and/or co-payments. The Seller Indemnitees shall use commercially reasonable efforts to collect any amounts available under such insurance coverage and from such other party alleged to have responsibility. If a Seller Indemnitee directly or indirectly receives any amount under insurance coverage or from such other party with respect to Seller Damages at any time subsequent to any indemnification provided by the Buyer under this Section 7.3, then such Seller Indemnitee shall promptly reimburse the Buyer for any payment made or expense incurred by the Buyer, or for the benefit of, the Buyer in connection with providing such indemnification up to such amount received by the Seller Indemnitee less any expenses of recovery, deductibles and/or co-payments; and

(iv) The Buyer shall be obligated to indemnify the Seller Indemnitees only for those claims giving rise to Seller Damages as to which the Seller Indemnitees have given the Buyer written notice thereof prior to the end of the applicable Survival Period. Any written notice delivered by a Seller Indemnitee to the Buyer with respect to Seller Damages shall set forth with as much specificity as is reasonably practicable the basis of the claim for Seller Damages and, to the extent reasonably practicable, a reasonable estimate of the amount of such claim.

7.4 Third-Party Indemnification. The obligations of the Seller to indemnify the Buyer Indemnitees under Section 7.2 with respect to Buyer Damages and the obligations of the Buyer to indemnify the Seller Indemnitees under Section 7.3 with respect to Seller Damages, in either case resulting from the assertion of liability by third parties (each, as the case may be, a “Claim”), shall be subject to the following terms and conditions:

(a) Any party against whom any Claim is asserted shall give the indemnifying party written notice of any such Claim promptly after learning of such Claim, and the indemnifying party may, at its option, undertake the defense of such Claim by representatives of its own choosing. Failure to give prompt notice of a Claim under this Agreement shall not affect the indemnifying party’s obligations under this Article 7, except to the extent the indemnifying party is materially prejudiced by such failure to give prompt notice. If the indemnifying party, within 30 days after notice of any such Claim, or such shorter period as is reasonably required, fails to assume the defense of such Claim, the Buyer Indemnitee or the Seller Indemnitee, as the case may be, against whom such Claim has been made shall (upon further notice to the indemnifying party) have the right to undertake the defense, compromise or settlement of such Claim on behalf of and for the account and risk, and at the expense, of the indemnifying party, subject to the right of the indemnifying party to assume the defense of such Claim at any time prior to settlement, compromise or final determination of such Claim;

(b) Anything in this Section 7.4 to the contrary notwithstanding, the indemnifying party shall not enter into any settlement or compromise of any action, suit or proceeding or consent to the entry of any judgment (i) that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Seller Indemnitee or the Buyer Indemnitee, as the case may be, of a written release from all liability in respect of such action, suit or proceeding or (ii) for other than monetary damages to be borne by the indemnifying party, without the prior written consent of the Seller Indemnitee or the Buyer Indemnitee, as the case may be, which consent shall not be unreasonably withheld. The indemnified party shall not enter into any settlement or compromise of any action, suit or proceeding or consent to the entry of any judgment; and

(c) The indemnifying party and the indemnified party shall cooperate fully in all aspects of any investigation, defense, pretrial activities, trial, compromise, settlement or discharge of any claim in respect of which indemnity is sought under this Article 7, including by providing the other party with reasonable access to employees and officers (including as witnesses) and other information.

7.5 No Setoff. Neither the Buyer nor the Seller shall have any right to setoff any Buyer Damages or Seller Damages, respectively, against any payments to be made by either of them under this Agreement.

7.6 Insurance. The indemnifying party shall be subrogated to the rights of any indemnified party in respect of any insurance relating to Buyer Damages or Seller Damages, as the case may be, to the extent of any indemnification payments made under this Agreement, and the indemnified party shall provide all reasonably requested assistance to the indemnifying party in respect of such subrogation.

7.7 No Duplication. Any liability for indemnification under this Agreement shall be determined to avoid duplication of recovery by reason of the state of facts (i) giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement or (ii) taken into account in determining any adjustment to the Purchase Price under Sections 1.10(d) and 4.14.

7.8 Sole Remedy.

(a) The parties agree that, from and after the Closing, the sole and exclusive remedy of any party to this Agreement, any Buyer Indemnitee or any Seller Indemnitee or their respective Affiliates with respect to this Agreement or any other claims relating to the events giving rise to this Agreement and the transactions provided for in this Agreement or contemplated by this Agreement shall be limited to the indemnification provisions set forth in Sections 4.8, 4.12, 4.13, 6.1(b), 8.8 and this Article 7 and, in furtherance of the foregoing, each of the parties, on behalf of itself and its Affiliates, waives and releases the other party to this Agreement (and such other party’s Affiliates) from, to the fullest extent permitted under any applicable Law, any and all rights, claims and causes of action it or its Affiliates may have against the other party to this Agreement with respect to the foregoing matters, except as provided by this Agreement.

(b) The parties intend that, even though indemnification and other obligations appear in various sections and articles of this Agreement, the indemnification procedures and limitations contained in this Article 7 shall apply to all indemnity and other obligations of the parties under this Agreement, except as provided in Sections 4.8, 4.12, 4.13, 6.1(b) and 8.8 and except to the extent expressly excluded in this Article 7.

7.9 No Special Damages. IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS ARTICLE 7 OR OTHERWISE IN RESPECT OF THIS AGREEMENT FOR EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGES EXCEPT TO THE EXTENT THAT SUCH DAMAGES ARISE FROM A THIRD PARTY CLAIM.

7.10 Express Negligence. THE FOREGOING INDEMNITIES ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING ANY EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

7.11 Tax Treatment of Indemnity Payments. Each of the Seller and the Buyer agrees to treat any indemnity payment made pursuant to this Agreement as an adjustment to the Purchase Price for all Tax purposes, unless otherwise required by applicable Laws.

ARTICLE 8

MISCELLANEOUS PROVISIONS

8.2 Entire Agreement; Assignment; Binding Effect. This Agreement (including the Seller Disclosure Letter and the Buyer Disclosure Letter), the Confidentiality Agreement and the documents listed in Sections 1.5 and 1.6 actually delivered at Closing constitute the entire agreement between the parties concerning the subject matter of this Agreement and supersede other prior agreements, understandings, covenants and representations, both written and oral, between the parties to the extent they relate in any way to the subject matter of this Agreement or the transactions contemplated hereby, and unless otherwise herein set forth, shall not be assigned, by operation of Law or otherwise, by a party, without the prior written consent of the other party. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns. No representation, covenant, warranty, promise, inducement or statement of intention has been made by either party hereto that is not embodied in this Agreement or such other documents, and neither party hereto shall be bound by, or be liable for, any alleged representation, warranty, promise, inducement or statement of intention not embodied herein or therein.

8.3 Severability. The invalidity or unenforceability of any term or provision of this Agreement in any situation or jurisdiction shall not affect the validity or enforceability of the other terms or provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction, and the remaining terms and provisions shall remain in full force and effect to the fullest extent permitted by law, unless doing so would result in an interpretation of this Agreement that is manifestly unjust.

8.5 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Texas applicable to contracts executed in and to be performed entirely within that state. All actions and proceedings arising out of or relating to this Agreement shall be heard and determined in any Texas state or federal court sitting in Houston, Texas, and the parties hereby irrevocably submit to the exclusive jurisdiction of such courts in any such action or proceeding and irrevocably waive the defense of an inconvenient forum to the maintenance of any such action or proceeding. Each party irrevocably consents to the service of any and all process in any such action or proceeding by the mailing of copies of such process to such party at its address specified in Section 8.4. The parties agree that a final, non-appealable judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Nothing in this Section 8.5 shall affect the right of any party to serve legal process in any other manner permitted by Law. The consents to jurisdiction set forth in this Section 8.5 shall not constitute general consents to service of process in the State of Texas and shall have no effect for any purpose except as provided in this Section 8.5 and shall not be deemed to confer rights on any person other than the parties.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE SUCH WAIVER, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVER, (C) IT MAKES SUCH WAIVER VOLUNTARILY AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.5(b).

8.6 Descriptive Headings; References. The descriptive headings used in this Agreement are inserted for convenience of reference only and shall in no way be construed to define, limit, describe, explain, modify, amplify, or add to the interpretation, construction or meaning of any provision of, or scope or intent of, this Agreement nor in any way affect this Agreement. When reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated.

8.7 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but any of which together shall constitute one and the same instrument. An executed counterpart signature page to this Agreement delivered by fax or other means of electronic transmission shall be deemed to be an original and shall be as effective for all purposes as delivery of a manually executed counterpart.

8.8 Fees and Expenses. Except as otherwise expressly set forth in this Agreement, all costs and expenses (including legal and financial advisory fees and expenses) incurred in connection with, or in anticipation of, this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such expenses; provided, however, the Buyer shall pay all fees relating to any filing made pursuant to any Antitrust Regulations. The Seller, on the one hand, and the Buyer, on the other hand, shall indemnify and hold harmless the other party from and against any and all claims or liabilities for financial advisory and finders’ fees incurred by reason of any action taken by such party or otherwise arising out of the transactions contemplated by this Agreement by any person claiming to have been engaged by such party or parties.

8.9 Interpretation. The phrase “to the knowledge of the Seller” or any similar phrase shall mean such facts and other information that as of the date of this Agreement are actually known to any director or executive officer of the Seller, after due inquiry. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.”

8.10 Third-Party Beneficiaries. This Agreement is solely for the benefit of the Seller, its successors and permitted assigns and the Seller Indemnitees, with respect to the obligations of the Buyer under this Agreement, and for the benefit of the Buyer, its successors and permitted assigns and the Buyer Indemnitees, with respect to the obligations of the Seller under this Agreement, and this Agreement shall not be deemed to confer upon or give to any other third party any remedy, claim of liability or reimbursement, cause of action or other right. The representations and warranties in this Agreement are the product of negotiations between the parties and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties of risks associated with particular matters regardless of knowledge of either of the parties. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

8.11 No Waivers. Except as otherwise expressly provided in this Agreement, no failure to exercise, delay in exercising, or single or partial exercise of any right, power or remedy by any party, and no course of dealing between the parties, shall constitute a waiver of any such right, power or remedy. No waiver by a party of any default, misrepresentation, or breach of warranty or covenant under this Agreement, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant under this Agreement or affect in any way any rights arising by virtue of any such prior or subsequent occurrence. No waiver shall be valid unless in writing and signed by the party against whom such waiver is sought to be enforced.

8.12 Specific Performance. The parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at Law or in equity.

8.13 Buyer Parent Guarantor Undertaking. Buyer Parent Guarantor, a corporation which is registered pursuant to the laws of Alberta, Canada, and which is the direct or indirect owner of all the outstanding shares of capital stock of the Buyer, hereby agrees to cause the Buyer to perform the actions required of it under this Agreement and absolutely and unconditionally guarantees the payment of all sums due hereunder and the performance of all of the Buyer’s duties described herein.
