THIS STOCK PURCHASE AGREEMENT (this “Agreement”), dated as of March 15, 2012, is entered into by and among TransAtlantic Petroleum Ltd., an exempted company incorporated with limited liability under the laws of Bermuda (“TAT”), Viking International Limited, an exempted company incorporated with limited liability under the laws of Bermuda (“VIL”), Viking Geophysical Services, Ltd., an international business company organized under the laws of Bahamas (“VGS”), and Viking Oilfield Services SRL, a limited liability company under the laws of Romania (“VOS SRL” and together with VIL and VGS, the “Acquired Companies”), TransAtlantic Worldwide, Ltd., an international business company organized under the laws of Bahamas (“TAW”), Longe Energy Limited, an exempted company incorporated with limited liability under the laws of Bermuda (“Longe”), TransAtlantic Petroleum (USA) Corp., a corporation incorporated under the laws of the State of Colorado, United States of America (“USA”), and TransAtlantic Petroleum Cyprus Limited, a limited liability company organized under the laws of Cyprus (“Cyprus,” and together with TAW, Longe and USA, “Sellers”), and Dalea Partners, LP, an Oklahoma limited partnership (“Buyer”).

RECITALS

A. Sellers are the record and beneficial owners of all of the issued and outstanding equity securities of each of the Acquired Companies as set forth onSchedule 1 to this Agreement (the “Shares”).

B. Sellers desire to sell to Buyer, and Buyer desires to purchase from Sellers, all of the Shares.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby confirmed, and subject to the terms and conditions set forth herein, TAT, the Acquired Companies, Sellers and Buyer, intending to be legally bound, hereby agree as follows:

ARTICLE I

DEFINITIONS

The terms defined inExhibit A, whenever used herein, shall have the meanings set forth inExhibit Afor all purposes of this Agreement. The definitions inExhibit Aare incorporated into this Agreement as if fully set forth at length herein and all references to a section in suchExhibit Aare references to such section of this Agreement.

ARTICLE II

SALE AND PURCHASE

2.1Purchase and Sale of Shares. At the Closing, subject to the terms and conditions of this Agreement, Sellers shall sell, transfer, assign and convey the Shares to Buyer, and Buyer shall purchase and accept the Shares from Sellers, and Buyer shall pay to Sellers the Closing Date Cash Consideration and shall deliver the Promissory Note. The “Closing Date Cash Consideration” (and, collectively with the Promissory Note, the “Purchase Price”) shall

be equal to $152,500,000. Sellers acknowledge and agree that, for the convenience of the parties, the Closing Date Cash Consideration, the Promissory Note (and any replacements or substitutions therefor), and all other payments to be made by Buyer to Sellers or TAT under this Agreement shall be paid to TAT, to be further allocated among the Sellers as determined by TAT. The Purchase Price shall be increased or decreased as provided below:

(a)Increases in the Purchase Price. The Purchase Price shall be increased by the Working Capital Overage, if any (as contemplated bySection 2.3(b)).

(b)Decreases in the Purchase Price. The Purchase Price shall be decreased by the Working Capital Underage, if any (as contemplated bySection 2.3(b)).

2.2Settlement Amounts. At the Closing, Buyer, based upon mutually agreed upon instructions with Sellers and against receipt by Buyer and Sellers of appropriate Lien releases and/or acknowledgments of payment from the relevant creditor entity, shall, out of the Closing Date Cash Consideration, on behalf of the Acquired Companies, cause to be paid in full the Acquired Company Debt (other than the Dalea Party Debt) to the party or parties entitled thereto pursuant to the Payoff Letters (which shall be delivered to Buyer and Sellers no later than three (3) Business Days prior to the Closing Date) (the “Settlement Amounts”).

2.3Working Capital Adjustment.

(a)Estimated Net Working Capital Statements. Not later than the third Business Day prior to the Closing Date, the Acquired Companies shall prepare and deliver, or cause to be prepared and delivered, to Buyer (i) an unaudited estimated balance sheet for each of the Acquired Companies as of the close of business on the day immediately preceding the Effective Date (the “Estimated Effective Date Balance Sheet”) and (ii) an estimated net working capital statement for each of the Acquired Companies, based on the Estimated Closing Balance Sheet (the “Estimated Net Working Capital Statement”), setting forth each Acquired Company’s calculation of the estimated Net Working Capital of such Acquired Company as of the close of business on the day immediately preceding the Effective Date and the aggregate amount of such calculations (the “Estimated Effective Date Net Working Capital”) calculated, in each case, in good faith and in accordance with GAAP using the same methodologies, procedures and principles set forth onExhibit B.

(b)Effective Date Adjustment. If the Estimated Effective Date Net Working Capital is less than zero, then the Purchase Price will be reduced (first, through an adjustment to the Promissory Note, and, to the extent the Promissory Note is reduced to zero, by a reduction of the Closing Date Cash Consideration) by an amount equal to the absolute value of such shortfall (a “Working Capital Underage”). If the Estimated Effective Date Net Working Capital is greater than zero, then the Purchase Price will be increased (through an adjustment to the Closing Date Cash Consideration) by an amount equal to such excess (a “Working Capital Overage”). If the Estimated Effective Date Net Working Capital is zero, then the Purchase Price will not be adjusted pursuant to thisSection 2.3(b), but may be subject to adjustment as otherwise provided in thisSection 2.3. The adjustments made at Closing pursuant to thisSection 2.3(b)are subject to subsequent adjustment as provided inSections 2.3(f)(i)and2.3(f)(ii).

2

(c)Final Net Working Capital Statement. Not later than 90 days after the Closing Date, Buyer shall cause to be prepared and delivered to TAT (i) unaudited balance sheets for each Acquired Company as of the close of business on the day immediately preceding the Effective Date (the “Final Effective Date Balance Sheets”) and (ii) a final net working capital statement, based on the Final Effective Date Balance Sheets (the “Final Net Working Capital Statement”), setting forth Buyer’s calculation of the Net Working Capital of the Acquired Companies, both individually and in the aggregate, as of the close of business on the day immediately preceding the Effective Date (the “Final Net Working Capital”) calculated, in each case, in good faith and in accordance with GAAP using the same methodologies, procedures and principles set forth onExhibit B.

(d)Dispute. Within 30 days following receipt by TAT of the Final Effective Date Balance Sheets and the Final Net Working Capital Statement, TAT may deliver a written objection notice to Buyer of any disagreement TAT has with respect to the preparation or content of the Final Effective Date Balance Sheets and/or the Final Net Working Capital Statement (such notice, an “Objection Notice”). An Objection Notice must describe in reasonable detail the line item calculations contained in the Final Effective Date Balance Sheets and/or the Final Net Working Capital Statement with which TAT disagrees and must briefly describe the basis for any such disagreement. If TAT does not provide an Objection Notice to Buyer within such 30-day period, such Final Effective Date Balance Sheets and Final Net Working Capital Statement will be final, conclusive and binding on the parties. In the event an Objection Notice is timely provided, Buyer and TAT shall negotiate in good faith to resolve the disputed items identified in the Objection Notice. If Buyer and TAT, notwithstanding such good faith efforts, fail to resolve any such disagreements within 30 days after Buyer’s receipt of an Objection Notice, then Buyer and TAT shall jointly engage the firm of Deloitte LLP, or, if Deloitte LLP is not then independent of Buyer and TAT or is not reasonably available to so act, then such other nationally recognized accounting firm as may be mutually acceptable to Buyer and TAT (or in the event the parties cannot agree, an accounting expert as chosen by the American Arbitration Association) (as applicable, the “Arbitration Firm”) to resolve any remaining disagreements;provided, that the Arbitration Firm shall determine only the disputed items identified in the Objection Notice that remain unresolved following the 30-day period described in this sentence. In addition, in resolving any such disputed items, the Arbitration Firm shall (i) be bound by the terms and conditions set forth in thisSection 2.3 andExhibit B, (ii) render its decision within 30 days after the referral of the dispute(s) to the Arbitration Firm for a decision pursuant hereto, and (iii) not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party. Neither TAT and Sellers, on one hand, nor Buyer, on the other hand, (and none of their respective representatives) shall have anyex parte conversations or meetings with the Arbitration Firm without the prior consent of (x) with respect to TAT and Sellers, Buyer and (y) with respect to Buyer, TAT. The fees, costs and expenses of the Arbitration Firm shall be allocated to and borne by Buyer, on the one

3

hand, and TAT, on the other hand, based on the inverse of the percentage that the Arbitration Firm’s determination (before such allocation) bears to the total amount of the total items in dispute as originally submitted to the Arbitration Firm. For example, should the items in dispute total in amount to $1,000 and the Arbitration Firm awards $600 in favor of Buyer’s position, 60% of the costs of its review would be borne by TAT and 40% of the costs would be borne by Buyer. All determinations made by the Arbitration Firm shall be final, conclusive and binding on the parties. Judgment may be entered upon the determination of the Arbitration Firm in any court having jurisdiction over the party against which such determination is to be enforced.

(e)Access. For purposes of complying with the terms set forth in thisSection 2.3, each party shall reasonably cooperate with and make reasonably available to the other parties and their respective representatives all information, records, data and working papers, including reasonable access to its facilities and personnel during normal business hours, as may be reasonably requested in connection with the preparation and analysis of the Final Effective Date Balance Sheets and the Final Net Working Capital Statement and the resolution of any disagreement related thereto;provided, that (i) such activities shall not unreasonably disrupt the operations of the Acquired Companies and (ii) the Acquired Companies shall have no obligation to make available any information if the Acquired Company has been advised by counsel that making such information available may jeopardize any attorney-client or other legal privilege or contravene any applicable Law or Contract in existence as of the Closing Date (including any confidentiality agreement to which the Acquired Company is a party). Buyer may require that TAT enter into a customary confidentiality agreement with respect to such information.

(f)Post-Closing Adjustment. Not later than the third Business Day after the date on which the Final Effective Date Balance Sheets and the Final Net Working Capital are finally determined pursuant toSection 2.3(d), TAT and Buyer shall jointly determine the amount by which the Purchase Price would have been adjusted pursuant toSection 2.3(b)had the Final Net Working Capital been substituted for the Estimated Effective Date Net Working Capital as of the Closing.

(i) If such substitutions would have resulted in a Purchase Price that is greater than the Estimated Closing Date Purchase Price (any such excess, the “Price Increase”), then Buyer shall within 30 days from the date on which the Final Effective Date Balance Sheets and the Final Net Working Capital are finally determined pursuant toSection 2.3(d) cover the Price Increase by payment of immediately available funds to TAT.

(ii) If such substitutions would have resulted in a Purchase Price that is less than the Estimated Closing Date Purchase Price (such deficit, the “Price Decrease”), then TAT shall return the original Promissory Note to Buyer against delivery of a modified Promissory Note the principal of which is reduced by the Price Decrease within five Business Days from the date on which the Final Effective Date Balance Sheets and the Final Net Working Capital are finally determined pursuant toSection 2.3(d). To the extent that the Price Decrease

4

exceeds the balance of the Promissory Note, TAT shall pay the amount of such excess to Buyer in immediately available funds within 30 days after the date on which the Final Effective Date Balance Sheets and the Final Net Working Capital are finally determined pursuant toSection 2.3(d).

(iii) If such substitutions would have resulted in a Purchase Price equal to the Estimated Closing Date Purchase Price, there shall be no adjustment to the consideration payable hereunder pursuant to thisSection 2.3(f).

The “Restricted Period” shall mean a period of five years from the Closing Date to the fifth anniversary of the Closing Date.

(b)Acquisitions by Selling Group. If during the Restricted Period any member of the Selling Group (the “Acquirer”) acquires any interest in any Person engaged in a Restricted Business that would otherwise be prohibited bySection 7.9(a), the Acquirer will give Buyer written notice of such acquisition within ten days after the consummation of such acquisition (the “Acquisition Notice”). Following delivery of the Acquisition Notice, the Acquirer shall provide Buyer with access to such information regarding the Offered Business (as defined below) as Buyer may reasonably request and shall promptly respond to Buyer’s questions regarding the Offered Business. Buyer shall have the right to purchase from the Acquirer the portion of such Person’s business constituting the Restricted Business (the “Offered Business”) on the terms set forth in thisSection 7.9(b). The Acquisition Notice shall include the Acquirer’s proposed purchase price for the Offered Business, which shall be the Acquirer’s reasonable allocation of the total consideration paid by the Acquirer for the interest acquired by it to the portion of such consideration attributable to the Offered Business. If Buyer desires to purchase the Offered Business, Buyer shall notify the Acquirer of such desire in writing not later than 60 days after the Acquirer has provided Buyer access to the information regarding the Offered Business, as set forth above, which notice shall include the purchase price and terms upon which Buyer offers to purchase the Offered Business (the “Offer Notice”). If Buyer fails to timely deliver an Offer Notice, Buyer’s right to purchase the Offered Business shall terminate, and the Acquirer shall be entitled to operate (but not expand) the Offered Business, for its own benefit but not for the purpose of providing such services to third parties, in substantially the manner operated prior to the acquisition of the Offered Business for the remainder of the Restricted Period. If Buyer timely delivers an Offer Notice, the Offer Notice shall either (i) accept the purchase price proposed in the Acquisition Notice, in which case Buyer shall be obligated to purchase, and the Acquirer shall be obligated to sell, the Offered Business on the terms set forth in the Acquisition Notice within 30 days after such Offer Notice is delivered by Buyer, or (ii) notify the Acquirer that Buyer disputes Acquirer’s allocation of the total consideration paid by the Acquirer for the interest acquired by it to the portion of such consideration attributable to the Offered Business, in which event the parties shall engage Hadco International Appraisal Services (“Hadco”) to appraise the Offered Business. If the price in such appraisal is higher than the purchase price provided in the Offer Notice, Buyer shall pay the fees and expenses of Hadco or, if the price in such appraisal is lower

25

than the purchase price provided in the Offer Notice, Acquirer shall pay the fees and expenses of Hadco. Within ten days following receipt of Hadco’s appraisal of the Offered Business, Buyer may revoke its offer to purchase the Offered Business, in which case, Acquirer shall be entitled to operate (but not expand) the Offered Business, for its own benefit but not for the purpose of providing such services to third parties, in substantially the manner operated prior to the acquisition of the Offered Business for the remainder of the Restricted Period. If Buyer does not timely revoke such offer, Acquirer shall be obligated to sell, and Buyer shall be obligated to purchase, the Offered Business at the price set forth in the appraisal within 30 days after the appraisal is delivered to Buyer.

(c)Non-Competition by Buyer. Buyer agrees that during the Restricted Period, Buyer will not, and Buyer will cause its Subsidiaries not to, without the prior written consent of TAT, engage directly or indirectly in oil and gas exploration and production, either as employer, consultant, agent, principal, proprietor, partner (general or limited), shareholder, member, manager, managing member, advisor, joint venturer, investor, lender, independent contractor or in any other individual or representative capacity, in the Restricted Region;provided, that nothing contained herein shall be construed to prevent Buyer or any of its Subsidiaries from investing in the capital stock of any Person engaged in oil and gas exploration and production that is listed on a national securities exchange or traded in the over-the-counter market so long as Buyer or such Subsidiary is not actively involved in the management of such Person and does not own more than 1% of the stock of such entity.

(d)Acquisitions. If during the Restricted Period, Buyer acquires any interest in any Person engaged in oil and gas exploration and production in the Restricted Region (the “E&P Business”), Buyer will give TAT written notice of such acquisition within ten days after the consummation of such acquisition (the “E&P Acquisition Notice”). Following delivery of the E&P Acquisition Notice, Buyer shall provide TAT with access to such information regarding the E&P Business as TAT may reasonably request and shall promptly respond to TAT’s questions regarding the E&P Business. TAT shall have the right to purchase from Buyer the portion of such Person’s business constituting the E&P Business on the terms set forth in thisSection 7.9(d). The E&P Acquisition Notice shall include Buyer’s proposed purchase price for the E&P Business, which shall be Buyer’s reasonable allocation of the total consideration paid by Buyer for the interest acquired by it to the portion of such consideration attributable to the E&P Business. If TAT desires to purchase the E&P Business, TAT shall notify Buyer of such desire in writing not later than 60 days after Buyer has provided TAT access to the information regarding the E&P Business, as set forth above, which notice shall include the purchase price and terms upon which TAT offers to purchase the E&P Business (the “E&P Offer Notice”). If TAT fails to timely deliver an Offer Notice, TAT’s right to purchase the E&P Business shall terminate, and Buyer shall be entitled to operate the E&P Business in substantially the manner operated prior to the acquisition of the E&P Business for the remainder of the Restricted Period but shall not be entitled to expand beyond the geographic area in which the E&P Business was permitted to operate prior to Buyer’s acquisition thereof. If TAT timely delivers an E&P Offer Notice, the E&P Offer Notice shall either (i) accept the purchase price proposed in the E&P Acquisition Notice, in

26

which case TAT shall be obligated to purchase, and Buyer shall be obligated to sell, the E&P Business on the terms set forth in the E&P Acquisition Notice within 30 days after such E&P Offer Notice is delivered by TAT, or (ii) notify Buyer that TAT disputes Buyer’s allocation of the total consideration paid by Buyer for the interest acquired by it to the portion of such consideration attributable to the E&P Business, in which event that parties shall engage a reputable appraiser to be agreed upon by Buyer and TAT to appraise the E&P Business. If Buyer and TAT are not able to agree on an appraiser, each shall select an appraiser, and such appraisers shall jointly select a third appraiser to appraise the E&P Business (such appraiser, or the appraiser agreed upon by Buyer and TAT, the “Appraiser”). If the price in such appraisal is higher than the purchase price provided in the E&P Offer Notice, TAT shall pay the fees and expenses of the Appraiser or, if the price in such appraisal is lower than the purchase price provided in the E&P Offer Notice, Buyer shall pay the fees and expenses of the Appraiser. Within ten days following receipt of the appraisal of the E&P Business, TAT may revoke its offer to purchase the E&P Business, in which case, Buyer shall be entitled to operate the E&P Business in substantially the manner operated prior to the acquisition of the E&P Business for the remainder of the Restricted Period but shall not be entitled to expand beyond the geographic area in which the E&P Business was permitted to operate prior to Buyer’s acquisition thereof. If TAT does not timely revoke such offer, Buyer shall be obligated to sell, and TAT shall be obligated to purchase, the E&P Business at the price set forth in the appraisal within 30 days after the appraisal is delivered to TAT.

(e)Non-Solicitation of Clients and Customers. During the Restricted Period, each member of the Selling Group agrees that it shall not (i) solicit clients or customers of any Acquired Company for the purpose of engaging in the Restricted Business or (ii) encourage any of such clients or customers to reduce or terminate its business with any of the Acquired Companies. During the Restricted Period, Buyer agrees that it shall not (i) solicit clients or customers of TAT or any Seller for the purpose of engaging in oil and gas exploration and production or (ii) encourage any of such clients or customers to reduce or terminate its business with TAT or any Seller.

(f)Non-Solicitation of Employees, Consultants and Agents. Each member of the Selling Group further agrees that it shall not induce or attempt to induce or encourage others to induce or attempt to induce, any Person who is or during the Restricted Period becomes an employee of, consultant to or agent of Buyer or any Acquired Company to terminate such Person’s employment with Buyer or an Acquired Company, as applicable (in the case of an employee), or cease providing its services to Buyer or an Acquired Company, as applicable (in the case of a consultant or agent);provided, that nothing herein shall restrict general solicitations through advertising or similar means which are not specifically directed at employees of, consultants to or agents of Buyer or any Acquired Company or employing or engaging anyone who responds to such general solicitations. Buyer further agrees that it shall not induce or attempt to induce or encourage others to induce or attempt to induce, any Person who is or during the Restricted Period becomes an employee of, consultant to or agent of TAT or any Seller to terminate such Person’s employment with TAT or any Seller, as applicable (in the case of an employee), or cease providing its services to TAT or any Seller, as applicable (in the case of a consultant or agent); provided, that nothing herein shall restrict general solicitations through advertising or similar means which are not specifically directed at employees of, consultants to or agents of TAT or any Seller or employing or engaging anyone who responds to such general solicitations.

27

(g)Specific Performance. The Parties acknowledge that a breach or violation of any or all of the covenants and agreements contained in thisSection 7.9 may cause irreparable harm and the damages in a monetary amount which may be virtually impossible to ascertain. As a result, each Party recognizes and acknowledges that each Party that is intended to benefit from such covenants and agreements shall be entitled, without the posting of any bond, to (i) a decree or order of specific performance to enforce the observance and performance of such covenant, obligation or other provision and (ii) an injunction from any court of competent jurisdiction enjoining and restraining any breach or violation of any or all of the covenants and agreements contained in this Agreement, either directly or indirectly, and that such rights shall be cumulative and in addition to all other rights and remedies available hereunder, at law or in equity.

(h)Review and Enforcement. Each Party has carefully read and considered the provisions of thisSection 7.9, and having done so, agrees that the restrictions set forth in thisSection 7.9 (including the time period of the restrictions and the geographical areas of restrictions set forth herein) are fair and reasonable and are reasonably required for the protection of the interests of the other Parties. Each member of the Selling Group further agrees that the ongoing business of the Acquired Companies has developed significant goodwill over the years, and they are agreeing to these restrictions in connection with sale of that goodwill and have received fair consideration in exchange for the covenants agreed by each member of the Selling Group under this Agreement. Buyer further agrees that it has received fair consideration in exchange for the covenants agreed by Buyer under this Agreement. In the event that, notwithstanding the foregoing, any part of the covenants set forth in thisSection 7.9 are held to be invalid or unenforceable by a court of competent jurisdiction, the Parties agree that such invalid or unenforceable provision(s) may be severed or modified in this Agreement without, in any manner, affecting the remaining portions hereof (all of which shall remain in full force and effect). In the event that any provision of thisSection 7.9 related to time period, areas, or activities of restriction shall be declared by a court of competent jurisdiction to exceed the maximum time period, area or activities such court deems reasonable and enforceable, said time period, area or activities of restriction shall be deemed modified to the minimum extent necessary to make the geographic or temporal restrictions or activities reasonable and enforceable.

(i)Independence. All covenants in thisSection 7.9 shall be construed as an agreement independent of any other provision of this Agreement or any other agreement or other transaction document, and the existence of any claim or cause of action of any member of the Selling Group against Buyer, any Acquired Company or any of their Affiliates, or any claim or cause of action of Buyer against any member of the Selling Group, as applicable, whether predicated on this Agreement or otherwise, shall not constitute a defense to enforcement such covenants.

28

7.10Transfer of Assets. Prior to Closing, and at the sole cost and expense of TAT and Sellers (including the payment of any related Taxes, including transfer Taxes), TAT and Sellers shall cause to be transferred to an Acquired Company or an Acquired Company Subsidiary designated by Buyer good title, free and clear of all Liens except for Permitted Liens, to each of the assets listed onSchedule 7.10, except to the extent any such asset is already owned by an Acquired Company; provided that to the extent any assets set forth onSchedules 4.7(b) or4.8(b) contemplated to be transferred pursuant to thisSection 7.10 are not able to be so transferred due to pending third party consents or regulatory approvals (“Non-Assignable Assets”), TAT and Sellers shall cause such transfers to occur as promptly as practicable after Closing, but in no event more than 120 days after Closing, and such Non-Assignable Assets shall be held, as of and from the Closing Date, by Sellers and TAT in trust for Buyer and the covenants and obligations thereunder shall be performed by Buyer in such Seller’s or TAT’s name and all benefits of and obligations existing thereunder shall be for Buyer’s account. Sellers and TAT shall take or cause to be taken such actions in its name or otherwise as Buyer may reasonably request so as to provide Buyer with the benefits of the Non-Assignable Assets and to effect the collection of money or other consideration that becomes due and payable under the Non-Assignable Assets, and each Sellers and TAT shall promptly pay over to Buyer all money or other consideration received by it in respect of all Non-Assignable Assets. As of and from the Closing Date, Sellers and TAT, on behalf of themselves and their Affiliates, authorize Buyer, to the extent permitted by applicable Law and the terms of the Non-Assignable Assets, to perform all the obligations and receive all the benefits of Sellers, TAT or their Affiliates under the Non-Assignable Assets and each appoint Buyer as its attorney-in-fact to act in its name on its behalf or in the name of any Affiliate of Sellers or TAT that is a party thereto and on such Affiliate’s behalf with respect thereto.

Notwithstanding the foregoing, disputes regarding current assets and current liabilities (including the nature and amount thereof) which are taken into account in computing the Net Working Capital underSection 2.3(d)shall not give rise to an indemnification claim hereunder.

34

10.4Limitations on Indemnification. Notwithstanding anything herein to the contrary, the indemnification rights and obligations provided for inSection 10.2 are subject to the following limitations:

(a) Notwithstanding anything to the contrary in this Agreement, the Buyer Indemnitees’ sole and exclusive remedy and source of recovery for any Losses pursuant to claims underSections 10.2(b)(i),10.2(b)(ii) (solely with respect to covenants or agreements to be performed prior to Closing), or10.2(c)(i) related to breaches of representations and warranties is the portion of the General Indemnity Amount remaining at any given time; provided that breaches of the Fundamental Representations shall not be limited to the portion of the General Indemnity Amount remaining at any given time but shall instead be limited to the full amount of the Purchase Price less any indemnification amounts previously paid by TAT or the Sellers to Buyer pursuant to this Agreement.

(b) No Buyer Indemnitee shall be entitled to indemnification pursuant toSections 10.2(b)(i),10.2(b)(ii) (solely with respect to covenants or agreements to be performed prior to Closing), or10.2(c)(i), (i) with respect to any single breach of representations and warranties or a pre-closing covenant unless the aggregate Losses arising from such breach exceeds $50,000 (the “Claim Threshold”) and (ii) until the aggregate amount of all Losses exceeding the Claim Threshold suffered by Buyer Indemnitees exceeds $2,000,000 (the “Basket”), provided that once the Basket of Losses exceeding the Claims Threshold exceeds $2,000,000, the Buyer Indemnitees shall be entitled to recover the entire amount of all such Losses resulting from all claims exceeding the Claim Threshold, including those included in achieving the Basket (subject toSection 10.4(a)).

(c) The limitations set forth inSection 10.4(a) andSection 10.4(b) shall not apply to (i) claims for fraud, or (ii) claims underSection 10.2(b)(i) (solely with respect to Fundamental Representations which shall be limited to the full amount of the Purchase Price less any indemnification amounts previously paid by TAT or the Sellers to Buyer pursuant to this Agreement),Section 10.2(b)(ii)(solely with respect to covenants or agreements to be performed after Closing),Section 10.2(b)(iii),Section 10.2(c)(i) (solely with respect to Fundamental Representations which shall be limited to the full amount of the Purchase Price less any indemnification amounts previously paid by TAT or the Sellers to Buyer pursuant to this Agreement) orSection 10.2(c)(ii).

(d) If any Losses sustained by an Indemnitee are covered by an insurance policy or an indemnification, contribution or similar obligation of another Person (other than an Affiliate of such Indemnitee), the Indemnitee shall use commercially reasonable efforts to collect such insurance proceeds or indemnity, contribution or similar payments. The amount of any Losses subject to indemnification underSection 10.2 shall be reduced by the amounts recovered by any Indemnitee, as applicable, under applicable insurance policies or an indemnification, contribution or similar obligation of another Person (other than an Affiliate of such Indemnitee) with respect to claims related to such Losses and if any Indemnitee receives such insurance proceeds or indemnity, contribution or similar payments after the settlement of any indemnification claim underSection 10.2, as applicable, such Indemnitee shall refund to the Indemnitor the amount of such insurance proceeds or indemnity, contribution or similar payments, up to the amount received in connection with such indemnification claim. It is the intention of the parties that no insurer or third party shall be entitled to any benefit or right it would not be entitled to receive in the absence of thisSection 10.4(d).

35

(e) Notwithstanding anything to the contrary contained in this Agreement or provided for under any applicable Law, no party hereto shall be liable under thisArticle X to any Indemnitee, either in contract or in tort, for any loss of profits or any consequential, incidental, exemplary, special or punitive damages of such Indemnitee, whether or not the possibility of such damages has been disclosed to the other party in advance, other than any such damages with respect to claims brought by a third party.

(f) The Buyer Indemnitees shall not be entitled to indemnification pursuant toSection 10.2(b)for Losses to the extent that any Buyer Indemnitee has been compensated therefor pursuant toSection 2.3 or otherwise.

(g) The Buyer Indemnitees’ right to indemnification pursuant toSection 10.2(b)andSection 10.2(c) shall be reduced by the amount of any reserve reflected in the 2011 Financial Statements specifically established for the specific items giving rise to such Loss or if such Loss is reflected in the Net Working Capital.

(h) Each Indemnitee shall use commercially reasonable efforts to mitigate any Loss for which such Indemnitee seeks indemnification.

(i) No Buyer Indemnitee shall be entitled to duplication of recovery for under thisArticle X with respect to breaches of representations, warranties, and covenants related to Taxes and employee claims underSection 10.2(b)(iii).

10.5Procedures.

(a)Notice of Losses by Seller Indemnitee. If a Seller Indemnitee has a claim for indemnification under thisArticle X that may result in a Loss (including any claim relating to a third party claim) (a “Claim”), such Seller Indemnitee shall, as soon as reasonably practicable after it becomes aware of such claim, give written notice thereof (a “Claims Notice”) to Buyer. A Claims Notice must describe the Claim in reasonable detail, and indicate the amount (estimated, as necessary and to the extent feasible) of the Loss that has been or may be suffered by the applicable Seller Indemnitee and include copies of all written documentation and summaries of all oral information actually known or in good faith believed by Seller to exist sufficient to establish the basis for the Claim. No delay in or failure to give a Claims Notice by Seller to Buyer pursuant to thisSection 10.5(a) will adversely affect any of the other rights or remedies that the applicable Seller Indemnitee has under this Agreement, or alter or relieve Buyer of its obligations to indemnify the applicable Seller Indemnitee except to the extent that it is materially prejudiced thereby. Buyer shall respond to Seller (a “Claim Response”) within 30 days (the “Response Period”) after the date that the Claims Notice is sent by Seller. Any Claim Response must specify whether or not Buyer disputes the Claim described in the Claims Notice. If Buyer fails to give a Claim Response within the Response Period, Buyer will be deemed not to dispute the Claim described in the related Claims Notice. If Buyer elects not to dispute a Claim described in a Claims Notice, whether by failing to give a timely Claim Response or otherwise, then the amount of Losses alleged in such Claims Notice will conclusively be deemed an obligation of Buyer, and Buyer shall pay or cause the Acquired Companies to pay, in cash, to Sellers

36

on behalf of the applicable Seller Indemnitees, within five days after the last day of the applicable Response Period the amount, if any, specified in the Claims Notice. If Buyer delivers a Claim Response within the Response Period indicating that it disputes one or more of the matters identified in the Claims Notice, Buyer and Sellers shall promptly meet and use their commercially reasonable efforts to settle the dispute. If Buyer and Sellers are unable to reach agreement within 30 days after the conclusion of the Response Period, then the dispute will be resolved in accordance withSection 12.10.

(b)Notice of Losses by Buyer Indemnitee.

(i)Claims with Determinable Losses. Subject to the limitations set forth in thisArticle X, if any Buyer Indemnitee has a claim for indemnification pursuant toSection 10.2(b) orSection 10.2(c) (a “Buyer Claim”) the amount of which is then known, Buyer shall, as soon as reasonably practicable after it becomes aware of such Buyer Claim, notify Seller of such Buyer Claim by means of a written notice specifying the nature, circumstances and amount of such Buyer Claim, including copies of any written documentation received from third parties and in Buyer’s possession and related to such Buyer Claim (an “Buyer Claim Notice” and, together with a Claims Notice, a “Notice”). The failure by Buyer to promptly deliver a Buyer Claim Notice under thisSection 10.5(b)(i) will not adversely affect the applicable Buyer Indemnitee’s right to indemnification except to the extent that Sellers are materially prejudiced thereby. If, within 30 days following receipt by Sellers of a Buyer Claim Notice (the “Dispute Period”), Buyer has not received from Sellers notice in writing that Sellers object to the Buyer Claim (or the amount of Losses set forth therein) asserted in such Buyer Claim Notice (a “Dispute Notice”), Sellers will be conclusively deemed to have agreed to and accepted Liability for the Buyer Claim and the amounts set forth in the Buyer Claim Notice, and Sellers shall pay, first, through a reduction in the then outstanding balance of the Promissory Note in an amount equal to the amount of such Buyer Claim, and second, in cash to the extent that the amount of such Buyer Claim exceeds the outstanding balance of the Promissory Note, to Buyer on behalf of the applicable Buyer Indemnitees, within five days after the last day of the applicable Dispute Period the amount specified in the Buyer Claim Notice, subject to the limitations contained in thisArticle X.

(ii)Claims Without Determinable Losses. Subject to the limitations set forth in thisArticle X, if any Buyer Indemnitee determines that it has a Buyer Claim the amount of which cannot reasonably be determined, Buyer shall, as soon as reasonably practicable after it becomes aware of such Buyer Claim, notify Sellers by means of a Buyer Claim Notice that contains the information required bySection 10.5(b)(i) and a good faith estimate, if possible, of Buyer’s calculation of the Losses incurred by the applicable Buyer Indemnitee with respect thereto. The failure by Buyer to promptly deliver an Buyer Claim Notice under thisSection 10.5(b)(ii) will not adversely affect the applicable Buyer Indemnitees’ right to indemnification except to the extent Sellers are materially prejudiced thereby. If Buyer has not received a Dispute Notice from Seller within the Dispute Period, Sellers will be conclusively deemed to have agreed to and

37

accepted Liability for the Buyer Claim, and Sellers shall pay from time to time as the amount of any such Buyer Claim becomes known, first, through a reduction in the then outstanding balance of the Promissory Note in an amount equal to the amount of such Buyer Claim, and second, in cash to the extent that the amount of such Buyer Claim exceeds the outstanding balance of the Promissory Note, to Buyer on behalf of the applicable Buyer Indemnitees, within five days after Buyer delivers Sellers notice of such amounts, the amount of such Buyer Claims, subject to the limitations contained in thisArticle X.

(iii)Disputes. If Sellers deliver a Dispute Notice to Buyer within the Dispute Period, Buyer and Sellers shall promptly meet and use their commercially reasonable efforts to settle the dispute as to whether and to what extent the Buyer Indemnitees are entitled to indemnification on account of such Buyer Claim. If Buyer and Sellers are unable to reach agreement within 30 days after Buyer receives such Dispute Notice, then the dispute will be resolved in accordance withSection 12.10. For all purposes of thisArticle X (including, without limitation, those pertaining to disputes underSection 10.5(a) and thisSection 10.5(b)(iii)), Buyer and Sellers shall cooperate with and make available to the other party and its respective representatives all information, records and data, and shall permit reasonable access to its facilities and personnel, as may be reasonably required in connection with the resolution of such disputes.

(c)Opportunity to Defend Third Party Claims. In the event of any claim by a third party against a Buyer Indemnitee or Seller Indemnitee for which indemnification is available hereunder, the Indemnitor has the right, exercisable by written notice to Buyer or Sellers, as applicable, within 30 days of receipt of a Notice from Buyer or Sellers, as applicable, to assume and conduct the defense of such claim with counsel selected by the Indemnitor, subject to the reasonable approval of the Indemnitee;provided, that Sellers shall not be entitled to assume the defense of a claim hereunder if (i) it involves potential criminal Liability of Buyer, any Acquired Company, or any of their employees, (ii) relief other than monetary damages is sought, or (iii) Buyer determines in good faith that the amount necessary to resolve such claims would materially exceed the amount recoverable under this Agreement. If the Indemnitor has assumed such defense as provided in thisSection 10.5(c), the Indemnitor will not be liable for any legal expenses subsequently incurred by any Indemnitee in connection with the defense of such Claim. If the Indemnitor does not, or is not permitted to, assume the defense of any third party claim in accordance with thisSection 10.5(c), the Indemnitee may continue to defend such Claim (and, subject to the limitations set forth in thisArticle X, the Indemnitor shall reimburse the Indemnitee for the reasonable expenses of defending such claim upon submission of periodic bills) and the Indemnitor may still participate in, but not control, the defense of such third party claim at the Indemnitor’s sole cost and expense. The Indemnitee shall not consent to a settlement of, or the entry of any judgment arising from, any such Claim, without the prior written consent of the Indemnitor (such consent not to be unreasonably withheld or delayed). Except with the prior written consent of the Indemnitee (such consent not to be unreasonably withheld or delayed), no Indemnitor, in the defense of any such claim, will consent to the entry of any judgment or enter into any settlement that (i) provides for injunctive or other nonmonetary relief affecting the Indemnitee, or

38

(ii) does not include as an unconditional term thereof the giving by each claimant or plaintiff to such Indemnitee of a release from all Liability with respect to such claim or litigation. In any such third party claim, the party responsible for the defense of such claim (the “Responsible Party”) shall, to the extent reasonably requested by the other party, keep such other party informed as to the status of such claim, including, without limitation, all settlement negotiations and offers. With respect to a third party claim for which Sellers are the Responsible Parties, Buyer shall use all commercially reasonable efforts to make available to Sellers and their representatives all books and records of Buyer and the Acquired Companies relating to such third party claim and shall cooperate with Sellers, at Sellers’ expense, in the defense of the third party claim.

(d)Settlement. The Responsible Party shall promptly notify the other party of each settlement offer with respect to a third party claim. Such other party shall promptly notify the Responsible Party whether or not such party is willing to accept the proposed settlement offer. If any such settlement offer is made to any claimant and rejected by such claimant, the amount payable to an Indemnitee with respect to such claim will not be limited to the amount of such settlement offer but will remain subject to all other limitations set forth in this Agreement. If the Indemnitor makes any payment hereunder on any third party claim, the Indemnitor shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnitee to any insurance benefits or other claims of the Indemnitee with respect to such third party claim.

ARTICLE XI

Sellers shall prepare and timely file, or cause to be timely filed, for each Acquired Company with reasonable assistance from each respective Acquired Company, all Tax Returns that are required by Law to be filed on or before the Closing Date and shall pay or cause to be paid all Taxes shown due thereon.

(a) Sellers hereby agree, jointly and severally, to be liable for and to indemnify and hold the Buyer Indemnitees harmless from and against, and pay to the Buyer Indemnitees the amount of any and all Losses in respect of (i) all Taxes of any Acquired Company and the Subsidiaries (or any predecessor thereof) for any Pre-Effective Date Tax Period, including the portion of any Straddle Period ending at the close of business on the Effective Date and (ii) any failure by Sellers to timely pay any and all Taxes required to be borne by Sellers pursuant toSection 11.5.

39

(c) The Acquired Companies will, in the discretion of Buyer and where not prohibited by Law, close the taxable periods of some or all the Acquired Companies and the Subsidiaries as of the close of business on the Effective Date. If applicable law does not permit the Acquired Company or a Subsidiary to close its taxable year on the Effective Date or Buyer does not exercise its discretion to do so, in any case in which a Tax is assessed with respect to or is attributable to a Straddle Period, the amount of Taxes attributable to the Pre-Effective Date Tax Period shall be determined on the basis of an interim closing of the books of the Acquired Companies as of the Effective Date, and the determination of the hypothetical Tax for such Pre-Effective Date Tax Period shall be determined on the basis of such interim closing of the books;provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on and including the Effective Date and the period beginning after the Effective Date in proportion to the number of days in each such period relative to the entire taxable period.

(d) Any and all transactions or events contemplated by this Agreement that occur on or prior to the Effective Date shall be deemed to have occurred in the Pre-Effective Tax Period.

11.3Cooperation; Audits.

(a) In connection with any audit examinations or Actions relating to the Tax liabilities imposed on any Acquired Company (or any successor thereof), Buyer, on the one hand, and Sellers, on the other hand, shall cooperate fully with each other, including the furnishing or making available during normal business hours of records, personnel (as reasonably required), books of account, powers of attorney or other materials necessary or helpful for the preparation of such Tax Returns, the conduct of audit examinations or the defense of Actions by Taxing Authorities as to the imposition of Taxes. Buyer shall and shall cause the Acquired Companies to retain all books and records with respect to Tax matters pertinent to the Acquired Company relating to any taxable period beginning before the Closing Date until the expiration of the applicable statute of limitations (including any extension thereof) for the respective taxable periods, and to abide by all record retention agreements entered into with any Taxing Authority. Notwithstanding the above, the control and conduct of any Action relating to Taxes that is a third-party Claim shall be governed bySection 10.5(c).

40

(b) Buyer and Sellers shall, upon request, use commercially reasonable efforts to obtain any certificate or other document from any Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

11.4Tax Refunds; Amended Tax Returns.

(a) Buyer shall promptly pay or cause to be paid to Sellers, or will set-off such amounts against any Tax Liability for the Pre-Effective Date Tax Period owed by Sellers, any Tax refunds attributable to the Acquired Company with respect to any Pre-Effective Date Tax Period that are received by Buyer or any Acquired Company (or any successor thereof) within ten days after the receipt of such refunds. At Sellers’ request, Buyer shall cooperate with Sellers in obtaining such reasonably available refunds, including through the filing of amended Tax Returns or refund claims as prepared by Seller, at Seller’s expense. Notwithstanding the foregoing, Sellers shall not file and Buyer shall not be obligated to file or cause any Acquired Company to file any amended Tax Return or refund claim that would result in additional Tax to Buyer or any Acquired Company or reduction of any Tax item.

(b) Neither Buyer nor any of its Affiliates shall amend, refile, revoke or otherwise modify any Tax Return or Tax election of any Acquired Company (or any successor(s) thereof) with respect to a taxable period (or portion thereof) ending on or prior to the Effective Date unless required to do so by a Taxing Authority or with the prior written consent of Sellers which shall not be unreasonably withheld.

11.5Transfer Taxes. Sellers shall be liable for and shall pay (and shall indemnify and hold harmless the Buyer Indemnitees against) all sales, use, stamp, documentary, filing, recording, transfer or similar fees or Taxes or governmental charges as levied by any Governmental Authority including any interest and penalties) in connection with the transfer of the Shares, or the transfer of any assets to the Acquired Companies or any Acquired Company Subsidiaries, contemplated by this Agreement.

11.6Disputes. Any dispute as to any matter covered by thisArticle XIshall be resolved by an Arbitration Firm. The fees and expenses of such Arbitration Firm shall be borne equally by TAT and Sellers, on the one hand, and Buyer, on the other hand. If any dispute with respect to a Tax Return is not resolved prior to the due date of such Tax Return, such Tax Return shall be filed in the manner which the party responsible for preparing such Tax Return deems correct.

11.7Time Limits. In accordance with the provisions ofArticle X, any claim for indemnity under thisArticle XI may be made at any time prior to 30 days after the expiration of the applicable Tax statute of limitations with respect to the relevant taxable period (including all periods of extension, whether automatic or permissive).
