The Buyer Closing Deliverables have been duly authorized by all necessary corporate action of the Buyer and the Parent, as the case may be, and constitute the valid and legally binding obligations of each of the Buyer and the Parent, as the case may be, enforceable against the Buyer or the Parent in accordance with their respective terms, except that the enforcement thereof may be subject to bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally and to general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law). Except as set forth in this Agreement, no consent, approval, or action of, filing with, or prior notice to any Governmental or Regulatory Authority on the part of the Buyer or the Parent is required in connection with the execution, delivery and performance of this Agreement or any other Buyer Closing Deliverable, except where the failure to obtain such consent or approval, or take such action, or file with or give such notice would not have a Material Adverse Effect.

(c) Compliance with Documents. Neither the Buyer nor the Parent is in violation or default of any material provisions of the Buyer Governing Documents. The execution, delivery, issuance and performance of the Buyer Closing Deliverables and the

purchase of the Equity Interests from Seller are not and will not be in conflict with or result in a violation or breach of, with or without the passage of time or the giving of notice or both, the Buyer Governing Documents, any judgment, order or decree of any court or arbitrator to which the Buyer or the Parent is a party or is subject, or any Material agreement, contract, license, lease or other similar instrument or obligation to which the Buyer or the Parent is a party or by which it is bound, except where such violation or breach would not have a Material Adverse Effect.

(d) Public Company Representations and Warranties.

(i) The Parent has filed on ▇▇▇▇▇ accurate and complete copies (excluding copies of exhibits) of each report, registration statement and definitive proxy statement filed by the Parent with the SEC between January 1, 2009 and the Effective Date or the Closing Date, as applicable (the “Parent SEC Documents”). As of the time it was filed with the SEC (or, if amended or superseded by a filing prior to the Effective Date, then on the date of such filing but only with respect to such amended or superseded portion): (A) each of the Parent SEC Documents complied as to form in all material respects with the applicable requirements of the Securities Act, or the Securities Exchange Act of 1934, as amended (as the case may be); and (B) none of the Parent SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(ii) The consolidated financial statements contained in the Parent SEC Documents: (A) complied as to form in all material respects with the published rules and regulations of the SEC applicable thereto; (B) were prepared in accordance with generally accepted accounting principles in the United States, applied on a consistent basis throughout the periods covered, except as may be indicated in the notes to such financial statements and (in the case of unaudited statements) as permitted by Form 10-Q of the SEC, and except that unaudited financial statements may not contain footnotes and are subject to year-end audit adjustments; and (C) fairly present the consolidated financial position of the Parent and its subsidiaries as of the respective dates thereof and the consolidated results of operations of the Parent and its subsidiaries for the periods covered thereby.

(e) Independent Evaluation. Each of the Buyer and the Parent is experienced and knowledgeable in the oil and gas business and is aware of its risks. Representatives of each of the Buyer and the Parent have visited the offices of the Seller and have been given opportunities to examine the Seller’s records, the Material Agreements and other materials made available to it by the Seller with respect to the Equity Interests and the Subsidiary Entities (the “Background Materials”). In entering into this Agreement, each of the Buyer and the Parent acknowledges and affirms that it has relied and will rely solely on the representations and warranties of the Seller set forth in this Agreement or other Seller Closing Deliverables and upon its own independent analysis, evaluation and investigation of, and judgment with respect to, the business, economic, legal, tax or other consequences of this transaction, including its own estimate and appraisal of the extent and value of the petroleum, natural gas and other reserves attributable to the assets owned by the Subsidiary Entities. Notwithstanding the foregoing, in no event shall the Knowledge of the Buyer or the Parent be used as a defense to the Seller’s breach of any representation or warranty under this Agreement or any other Seller Closing Deliverables or be used to limit or release the Seller from the Seller’s indemnity obligations under Section 9.

(f) OFAC Compliance.

(i) Each of the Buyer and the Parent has fully reviewed the Office of Foreign Assets Control (“OFAC”) website at ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/▇▇▇▇. Each of the Buyer and the Parent represents and warrants that the assets to be invested by it in the Equity Interests were not and are not directly or indirectly derived from activities that contravene federal, state or international laws and regulations, including anti-money laundering laws and regulations. Federal regulations and executive orders administered by OFAC prohibit, among other things, the engagement in transactions with, and the provision of services to, certain foreign countries, territories, entities and individuals. Each of the Buyer and the Parent has reviewed the lists of OFAC prohibited countries, territories, persons and entities found on the OFAC website at ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/▇▇▇▇ (the “OFAC Lists”). In addition, each of the Buyer and the Parent acknowledges that the programs administered by OFAC (the “OFAC Programs”) prohibit dealing with individuals or entities in certain countries regardless of whether such individuals or entities appear on the OFAC Lists.

(ii) None of: (A) the Buyer or the Parent; (B) any person controlling or controlled by the Buyer or the Parent; or (C) any person for whom the Buyer or the Parent is acting as agent or nominee in connection with an investment in the Equity Interests is a country, territory, individual or entity named on an OFAC List, or a person or entity prohibited under the OFAC Programs.

6. Further Assurances. The Parties agree that with respect to the period following the Closing, in case at any time after the Closing any further action is necessary or desirable to carry out the purposes of this Agreement or the Assignment, each of the Parties will take such further action (including the execution and delivery of such further instruments and documents) as the other Party reasonably may request, including, but not limited to, securing any and all consents and approvals from any Governmental or Regulatory Authority necessary to consummate the purchase and sale of the Equity Interests and Receivables. Without limiting the foregoing, the Seller shall, at its own expenses, execute and deliver such further instruments and documents and cooperate diligently and in good faith with the Buyer to promptly complete the transfer of the limited liability company shares in Direct Bulgaria and the registration thereof in the Republic of Bulgaria. The Seller acknowledges and agrees that from and after the Closing the Buyer will be entitled to possession of all documents, books, records, agreements and financial data of any sort relating to any of the Subsidiary Entities.

7. Tax Matters.

(a) Cooperation on Tax Matters. The Buyer and the Seller shall, and shall cause each of the Subsidiary Entities to, cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Each of the Buyer and the Seller agrees (i) to retain all books and records with respect to Tax matters pertinent to any of the Subsidiary Entities relating to any taxable

period until the expiration of the statute of limitations and to abide by all record retention agreements entered into with any Taxing Authority (in the case of each Party, other than record retention agreements that do not bind such Party with respect to which such Party has no notice), and (ii) if one Party so requests, the other Party shall allow the requesting Party to make copies of such books and records.

(b) Certain Taxes and Fees. All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid by the Buyer when due, and the Buyer will, at its own expense, file or cause to be filed all necessary Tax Returns and other documentation with respect to all such Taxes, fees and charges. For the avoidance of doubt, the Seller shall pay (or cause to be paid) all U.S. federal, Bulgarian, Moroccan, state and local income, capital gain, franchise or similar taxes imposed on the Seller (or its parent) with respect to the Seller’s sale of the Equity Interests and Receivables. Seller shall pay and be responsible for all taxes for each of the Subsidiary Entities arising from their operations during calendar year 2010.

(c) Tax Free Transaction. The Seller and the Buyer hereby agree that the purchase and sale of the Equity Interests and Receivables is intended to be a tax free transaction pursuant to Section 368(a)(1)(c) of the Internal Revenue Code of the United States; provided, however, whether the transaction ultimately qualifies as a tax free transaction under applicable law shall not impact any of the transactions contemplated by this Agreement or other Closing Deliverables.

8. Post Closing Covenants and Obligations. In addition to the obligations of the Parties set forth in Sections 6 and 7, the Buyer and Seller agree as follows:

(a) Buyer agrees that during the twelve month period after the Closing, the Buyer will have completed drilling and testing the HKE-1 bis Well or the GRB-1 Well. Notwithstanding anything to the contrary set forth in this Agreement, each of the Buyer, the Parent and the Seller agrees that it would be impracticable and extremely difficult to ascertain the amount of actual damages caused by a breach of this Section 8(a). Therefore, the Buyer, the Parent and the Seller agree that, in the event it is established that the Buyer has violated the first sentence of this Section 8(a), then (i) the Seller shall have earned, and the Buyer and the Parent shall as soon as reasonably practicable after the date twelve months after the Closing Date deliver to the Seller, shares of Parent Common Stock having a value of Three Million U.S. Dollars (USD $3,000,000) (the number of shares to be issued to be calculated by dividing $3,000,000 by the volume weighted average price per share of the Parent Common Stock on the NYSE Amex Stock Exchange for the ten (10) trading days ending on the one year anniversary of the Closing Date); and (ii) in the event at any time prior to the end of the twenty-four month period following the Closing the Buyer completes (albeit in a non-timely manner) the obligations set forth in this Section 8(a) and achieve a Morocco Success, then the Seller shall have earned, and the Parent and the Buyer will as soon as reasonably practicable thereafter deliver to the Seller, additional shares of Parent Common Stock having a value of Three Million U.S. Dollars (USD $3,000,000) (the number of shares to be issued to be calculated by dividing $3,000,000 by the volume weighted average price per share of the Parent Common Stock on the NYSE Amex

Stock Exchange for the ten (10) trading days prior to the day the 72-hour deliverability test made a part of the definition of Commercial Success – Morocco for the first of either the HKE-1 bis Well or the GRB-1 Well to so qualify is finished). Each of the Buyer, the Parent and the Seller further agrees that this liquidated damages provision represents reasonable compensation for the loss which would be incurred by the Seller due to any such breach. For avoidance of doubt, delivery of Parent Common Stock under Section 8(a)(i) or Section 8(a)(ii) above shall release the Buyer and the Parent from their obligations under Section 2(c)(i).

(b) Buyer agrees that the Buyer will (x) have commenced drilling the Deventci-R2 Well during the nine month period after the Closing, (y) be continuously diligently proceeding to drill the Deventci-R2 Well to a depth sufficient to test the Ozirovo formation beginning on the commencement of the Deventci-R2 Well through the end of the twenty-four month period after the Closing, and (z) drill the Deventci-R2 Well to a depth sufficient to test the Ozirovo formation and test the Deventci-R2 Well prior to the end of the twenty-four month period after the Closing; provided, however, in the event the Buyer has drilled to sufficient test depth in accordance with standard industry practice and reasonably determines, based on the well, seismic and other geophysical data, that the Deventci-R2 Well is unlikely to be completed to achieve production in commercial quantities, then the Buyer shall have no obligation to complete the Deventci-R2 Well or to conduct the 72 hour deliverability test for the Deventci-R2 Well to determine whether a Bulgaria Success has been achieved. In connection with that decision, the Buyer shall plug and permanently abandon the Deventci-R2 Well. Notwithstanding anything to the contrary set forth in this Agreement, each of the Buyer, the Parent and the Seller agrees that it would be impracticable and extremely difficult to ascertain the amount of actual damages caused by a breach of this Section 8(b). Therefore, the Buyer, the Parent and the Seller agree that, in the event it is established that the Buyer has violated any of the provisions of the first sentence of Section 8(b), then (i) the Seller shall have earned, and the Buyer and the Parent shall as soon as reasonably practicable after the date of such violation (i.e., nine months or twenty-four months, as applicable, after the Closing Date) deliver to the Seller, shares of Parent Common Stock having a value of Five Million U.S. Dollars (USD $5,000,000) (the number of shares to be issued to be calculated by dividing $5,000,000 by the volume weighted average price per share of the Parent Common Stock on the NYSE Amex Stock Exchange for the ten (10) trading days prior to the date of such violation (i.e., nine months or twenty-four months, as applicable, after the Closing Date); provided, however, in no event shall the Seller be entitled to recover more than once under this Section 8(b)(i) even if the Buyer has violated more than one provision of this Section 8(b); and (ii) in the event at any time prior to the end of the twenty-four month period following the Closing (or such longer period necessary to test and complete such well if such testing or completion is in process as of the end of the twenty-four month period following the Closing), the Buyer completes (albeit in a non-timely manner) the obligations set forth in this Section 8(b) and achieves a Bulgaria Success, then the Seller shall have earned, and the Parent and the Buyer will as soon as reasonably practicable thereafter deliver to Seller, additional shares of Parent Common Stock having a value of Five Million U.S. Dollars (USD $5,000,000), with such shares to be issued by the Parent upon the earlier to occur of (A) the Buyer executing a multi-year gas sales contract for the sale of all or substantially all of the gas produced by such well (with such gas sales contract to be in form and substance satisfactory to the Buyer) or (B) the date the Deventci-R2 Well is connected to the Bulgartransgas or any other pipeline with significant deliverability. The number of shares to be issued is to be calculated by dividing $5,000,000 by the volume weighted average price per share of the Parent Common Stock on the

NYSE Amex Stock Exchange for the ten (10) trading days prior to the day the 72-hour deliverability test made as part of the definition of Commercial Success – Bulgaria for the Deventci-R2 Well to so qualify is finished. Each of the Buyer, the Parent and the Seller further agree that this liquidated damages provision represents reasonable compensation for the loss which would be incurred by the Seller due to any such breach. For avoidance of doubt, the Seller hereby agrees that: (X) delivery of Parent Common Stock under Section 8(b)(i) or Section 8(b)(ii) above shall release the Buyer and the Parent from their obligations under Section 2(c)(ii), and (Y) in the event that the Buyer complies with the first sentence of this Section 8(b) but reasonably determines that the Deventci-R2 Well is unlikely to be completed to achieve production in commercial quantities as provided in the first sentence of this Section 8(b), then no shares shall be due under this Section 8(b) or Section 2(c)(ii).

(c) Buyer agrees that during the twelve month period after the Closing, the Buyer will have completed drilling the Deventci-R2 Well to a depth sufficient to penetrate through and extract a core specimen from the Etropole Shale formation and have penetrated through and extracted a core specimen from the Etropole Shale formation. If required to secure a production concession for the Etropole Shale, then Buyer will, within the twelve month period following the Closing Date, commence the drilling of a second well to penetrate through the Etropole Shale formation. Before the expiration of the A-Lovech Exploration License (as may be extended), the Buyer shall submit an application for a production concession for the Etropole Shale covering the largest acreage which the Buyer reasonably believes is justified based on the well, seismic and other geophysical data, but only to the extent that the Buyer reasonably determines that the data collected during the respective period establishes that a production concession for the Etropole Shale will be granted to the Buyer. Notwithstanding anything to the contrary set forth in this Agreement, each of the Buyer, the Parent and the Seller agrees that it would be impracticable and extremely difficult to ascertain the amount of actual damages caused by a breach of this Section 8(c). Therefore, the Buyer, the Parent and the Seller agree that, in the event it is established that the Buyer has violated any of the provisions of the first three (3) sentences of Section 8(c), then (i) the Seller shall have earned, and the Buyer and the Parent shall as soon as reasonably practicable after the date of such violation (i.e., twelve months after the Closing Date or the expiration date of the A-Lovech Exploration License, as applicable) deliver to the Seller, shares of Parent Common Stock having a value of Five Million U.S. Dollars (USD $5,000,000) (the number of shares to be issued to be calculated by dividing $5,000,000 by the volume weighted average price per share of the Parent Common Stock on the NYSE Amex Stock Exchange for the ten (10) trading days prior to the date of such violation (i.e., the twelve months after the Closing Date or the expiration date of the A-Lovech Exploration License, as applicable); provided, however, in no event shall the Seller be entitled to recover more than once under this Section 8(c)(i) even if the Buyer has violated more than one provision of this Section 8(c); and (ii) in the event at any time prior to the end of the thirty month period following the Closing, the Buyer completes (albeit in a non-timely manner) the obligations set forth in this Section 8(c) and achieves a Shale Success, then the Seller shall have earned, and the Parent and the Buyer will as soon as reasonably practicable thereafter deliver the Seller, additional shares of Parent Common Stock having a value of Five Million U.S. Dollars (USD $5,000,000) (the number of shares to be issued to be calculated by dividing $5,000,000 by the volume weighed average price per share of the Parent Common Stock on the NYSE Amex Stock Exchange for the ten (10) trading days prior to the date such production concession is granted). Each of the Buyer, the Parent and the Seller further agrees that this liquidated damages provision represents

reasonable compensation for the loss which would be incurred by the Seller due to any such breach. For avoidance of doubt, Seller hereby agrees that (X) delivery of Parent Common Stock under Section 8(c)(i) or Section 8(c)(ii) above shall release the Buyer and the Parent from their obligations under Section 2(c)(iii), and (Y) in the event that the Buyer complies with the first two sentences of this Section 8(c) but does not apply for a production concession for the Etropole Shale because it has reasonably determined that a production concession for the Etropole Shale will not be granted to the Buyer as provided in the third sentence of this Section 8(c), then no shares shall be due under this Section 8(c) or Section 2(c)(iii).

(d) Sole Remedy. The Seller hereby agrees and acknowledges that the liquidated damages provisions set forth in Sections 8(a), 8(b), and 8(c) above are the exclusive rights and remedies of the Seller for any breach by the Buyer of its covenants and obligations under Sections 8(a), 8(b) and 8(c).

(e) Seller Guarantees. To the extent not released at Closing, the Buyer and the Parent shall use their respective commercially reasonable efforts to have the Seller released from those Seller guarantees set forth on Schedule 2(g)(iv).

(f) Sale or Divestment. To the extent the Buyer or the Parent has any outstanding obligations under Section 2(c) or Sections 8(a), 8(b) or 8(c), each of the Buyer and the Parent shall, prior to any sale or divestment by the Buyer of the Equity Interests or all or substantially all of the assets held by the Subsidiary Entities or any acquisition or merger of the Buyer that includes the assets held by the Subsidiary Entities, ensure that such purchaser or acquiror (or the ultimate parent entity thereof) agrees to assume all of the Buyer’s obligations set forth in this Agreement; provided, however, that in the event the purchaser or acquiror (or the ultimate parent entity thereof) is not a publicly traded company with a market capitalization of at least USD $1,000,000,000, then any obligations set forth in this Agreement to provide Additional Consideration hereunder shall become an all cash obligation without any marketability discount.

(g) Performance. The Seller hereby agrees and acknowledges that, at the sole discretion of the Buyer, the covenants and obligations of the Buyer under Sections 8(a), 8(b), and 8(c) may be performed by an applicable Subsidiary Entity, one or more Affiliates of the Buyer or the applicable Subsidiary Entity, or one or more third Persons.

9. Indemnification.

(a) Indemnification with respect to Representations and Warranties. The Seller shall indemnify and hold harmless the Buyer and each of its members, managers, officers, shareholders, directors, employees, agents and Affiliates (collectively, the “Buyer Indemnitees”) for any Losses paid, incurred, sustained or accrued by any Buyer Indemnitee that arises out of or in connection with (i) any breach of any representation, warranty or covenant made by the Seller concerning the Seller or any of the Subsidiary Entities contained in this Agreement or in any other Seller Closing Deliverable or (ii) any Action or Proceeding arising from any exercise by Seller’s shareholders of dissenters’ or similar rights.

(b) Procedures.

(i) Any Buyer Indemnitee that intends to seek indemnification for any Losses hereunder shall promptly deliver to the Seller a notice (a “Loss Notice”) describing in reasonable detail the facts giving rise to any Losses (and any underlying Action or Proceeding) and setting forth all claims and shall include in such Loss Notice (if then known) the amount or the method of computation of the amount of such Loss and a reference to the provision of this Agreement or any other Closing Deliverable executed or delivered pursuant hereto or in connection herewith upon which such Loss is based. To the extent the Loss Notice pertains to an Action or Proceeding brought by a third Person: (A) the failure to notify the Seller shall not relieve it from any liability which it may have under this Section 9 except to the extent it has been materially prejudiced by such failure; (B) the Seller shall be entitled to participate therein and, to the extent that it wishes, to assume the defense of such Action or Proceeding with counsel of its own choosing and at its own expense, in which case the Seller shall not be liable to such Buyer Indemnitee under this Section 9 for any legal or other expenses subsequently incurred by such Buyer Indemnitee in connection with the defense thereof; provided, however, that such Buyer Indemnitee shall have the right to employ one counsel (plus one local counsel) to represent it and any other Buyer Indemnitees who may be subject to liability arising out of any Action or Proceeding in respect of which indemnity may be sought under this Section 9 if (1) the Seller and the Buyer Indemnitee shall have so mutually agreed or (2) the named parties in any such proceeding (including any impleaded parties) include both the Buyer Indemnitees, on the one hand, and the Seller, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the reasonable fees and expenses of such separate counsel shall be paid by the Seller; (C) neither the Seller nor any Buyer Indemnitee shall, without the prior written consent of the other party, which consent shall not be unreasonably withheld, settle or compromise or consent to the entry of any judgment with respect to any such pending or threatened Action or Proceeding unless such settlement, compromise or consent includes an unconditional release of each Buyer Indemnitee or Seller, as the case may be, from all liability arising out of such Action or Proceeding.

(ii) If the Loss Notice does not pertain to an Action or Proceeding brought by a third Person, the Seller shall have five (5) days after the giving of any Loss Notice to (A) agree to the amount or method of determination set forth in the Loss Notice and to pay such amount to such Buyer Indemnitee in immediately available funds, or (B) provide such Buyer Indemnitee with notice that it disagrees with the amount or method of determination set forth in the Loss Notice (the “Dispute Notice”). Within thirty (30) days after the giving of the Dispute Notice, representatives of Seller and such Buyer Indemnitee shall negotiate in a bona fide attempt to resolve the matter.

(i) Except to the extent otherwise provided in this Agreement (including, without limitation, Section 9(c)(ii) below), the Seller’s obligations to indemnify the Buyer Indemnitees against, or reimburse the Buyer Indemnitees for, any Losses under Section 9 are subject to the following: (A) with respect to claims made within the first six (6) months after the Closing Date, the Seller shall have no obligation to indemnify the Buyer Indemnitees against,

or reimburse any Buyer Indemnitees for, any Losses after the aggregate amount of all payments made by the Seller under Section 9 in respect of Losses equals fifty percent (50%) of the Purchase Price received by the Seller at the time of such claim, provided that any Losses in excess of such amount may be applied against fifty percent (50%) of the amount of Additional Consideration, if any, to be paid to the Seller, and (B) with respect to claims made after the first six (6) months after the Closing Date and on or prior to the respective expiration dates of the representations and warranties pursuant to Section 10, the Seller shall have no obligation to indemnify the Buyer Indemnitees against, or reimburse any Buyer Indemnitees for, any Losses after the aggregate amount of all payments made by the Seller under Section 9 in respect of Losses equals twenty five percent (25%) of the Purchase Price received by the Seller at the time of such claim, provided that any Losses in excess of such amount may be applied against twenty five percent (25%) of the amount of Additional Consideration, if any, to be paid to the Seller, including any amounts paid pursuant to Section 9(c)(i)(B) above.

(ii) In no event shall the limitations set forth in Section 9(c) apply to: (A) any breach by the Seller of its representations and warranties under Section 3(c), or (B) any Losses caused by the fraudulent act or willful misconduct of the Seller. In either event, the Seller shall indemnify the Buyer Indemnitees against, or reimburse the Buyer Indemnitees for, the full amount of any and all Losses.

(d) Sole Remedy. The indemnification provisions set forth in this Section 9 are the exclusive rights and remedies of the Buyer Indemnitees for any inaccuracy or breach of the representations, warranties, covenants and obligations made in this Agreement except for the remedies of specific performance, injunction and other equitable relief.

(e) Set Off. The Seller hereby agrees and acknowledges that the Buyer may, at its sole discretion, offset any or all amounts of Losses subject to Section 9(c)(i) against any Additional Consideration payable to the Seller under Section 2(c) or unpaid royalty amounts due to the Seller arising under the Overriding Royalty Interest Agreement – 1%. The Seller agrees that Buyer and Parent may withhold any such Additional Consideration or royalty amounts based on claims for indemnification made in good faith by the Buyer pending final resolution of such claims by settlement, final judgments or otherwise. Buyer and Parent acknowledge and agree that Seller may distribute the Restricted Securities to its shareholders pursuant to Section 2(k) hereof and that Buyer and Parent will not make any claim for indemnification against the members of the Board of Directors of the Seller in connection with any such distribution occurring six months after the Closing, provided that the Seller reserves a sufficient number of shares of Restricted Securities to satisfy any claims for indemnification made prior to the date of such distribution.

10. Survival of Representations and Warranties. All of the representations, warranties and covenants of the Parties contained in this Agreement or in any Seller Closing Deliverable shall survive the Closing hereunder and shall continue in full force and effect for a period of two (2) years thereafter; provided, however, that the representations and warranties of the Seller (x) regarding Taxes shall continue until the expiration of the applicable statute of limitations and (y) regarding due authorization, valid formation, valid existence, and legal compliance shall continue to survive indefinitely in full force and effect following the Closing Date. Notwithstanding the foregoing, any and all claims for indemnification made under Section 9 on or prior to the expiration of the respective representations and warranties shall remain in full force and effect until their resolution in full.

11. Termination.

(a) Termination. This Agreement may be terminated in accordance with the following provisions:

(ii) the Parties shall, in all events, remain bound and continue to be subject to the provisions set forth in Section 13(k).

12. Assignment of Agreement.

(a) The Seller acknowledges and agrees that the Buyer may assign its rights to acquire any of the Equity Interests or Receivables to a third party who is either (i) an Affiliate of the Buyer or (ii) a newly formed entity controlled by the Buyer, the purpose of which entity is to acquire such Equity Interests and/or Receivables. Without limiting the foregoing, the Seller hereby specifically acknowledges and agrees that the Buyer may, at its sole option, assign its

right to acquire the limited liability company shares in Direct Bulgaria and/or the Receivables with respect to Direct Bulgaria to TransAtlantic Petroleum Cyprus Limited (“Cyprus”), an Affiliate of the Buyer, provided that the Parent guarantee set forth in Section 13(j) remains applicable with respect to Cyprus. Prior to Closing the Buyer will notify the Seller of any such assignment and the identity of such assignee(s). Upon such notice any such assignee shall be deemed a third party beneficiary of this Agreement with full independent rights to (a) rely on the representations, warranties and covenants contained herein and (b) enforce all rights and obligations hereunder, as to the Equity Interests and Receivables assigned to such assignee. From and after the date of any notice regarding any assignee, the term “Buyer” shall be deemed to include Buyer and any such assignee(s). Any such assignment shall not relieve the Buyer or the Parent of any of its obligations hereunder.

(b) The Buyer and the Parent acknowledge and agree that Seller may assign its rights and obligations under this Agreement to one Affiliate of the Seller in connection with the dissolution of Seller, provided (i) that such assignee shall be bound by all of the terms and provisions of this Agreement, including, without limitation, the securities representations contained in Section 2(j) and the indemnification obligations contained in Section 9, as if it were the Seller; and (ii) that the Seller shall not dissolve earlier than November 30, 2011. The assignee shall assume all of the Seller’s obligations under this Agreement and the Seller shall remain fully liable for its obligations under this Agreement. Such assignment shall only be effective upon receipt of the Buyer and the Parent of an assignment and assumption of obligations and such other documentation in form and substance reasonably acceptable to the Buyer and the Parent.

(g) Governing Law and Jurisdiction. This Agreement shall be governed by, construed and interpreted in accordance with the domestic laws of the State of Texas without giving effect to any choice or conflict of law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Texas. Any and all suits, proceedings and other actions relating to, arising out of or in connection with this Agreement or any other Closing Deliverables shall be submitted to the in personam jurisdiction of the courts of the State of Texas and venue for all such suits, proceedings and other actions shall be in Dallas County, Texas.

No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

(i) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

As a material inducement to the Seller’s willingness to enter into this Agreement and perform its obligations hereunder, the Parent hereby unconditionally guarantees the full performance and payment by the Buyer (or its successors and assigns) of each of its covenants, obligations and undertakings pursuant to or otherwise in connection with this Agreement and the transactions contemplated by this Agreement (including, without limitation, any obligations to pay Additional Consideration) and hereby represents, acknowledges and agrees that any breach of, or other failure to perform, any such representation, warranty, covenant, obligation, agreement or undertaking of the Buyer (or its successors and assigns) shall also be deemed to be a breach or failure to perform by the Parent, and the Seller, if applicable, shall have the right, exercisable in the Seller’s or such person’s sole discretion, to pursue any and all available remedies the Seller or such person may have arising out of any such breach or nonperformance directly against either or both of the Parent and the Buyer (or its successors and assigns) in the first instance.

(k) Confidentiality. Each of the Seller, the Parent and the Buyer covenants and agrees to, and agrees to cause and require their respective Affiliates and each such Party’s directors, officers, employees, agents, financial advisors, attorneys and accountants to, keep confidential and not make any disclosure regarding (i) the terms of this Agreement or the transactions contemplated hereby or (ii) any Party’s Confidential Information (as defined below), except as may be required by law. For purposes of this Section 13(k) the term “Confidential Information” means any and all confidential and/or proprietary knowledge, data or information of either the Seller, the Parent or the Buyer delivered to the other Party pursuant to this Agreement or in the course of the diligence and negotiation of this Agreement, except information that (i) was in the public domain at the time it was communicated; (ii) entered the public domain, through no fault of the Party receiving such information pursuant to this Agreement, subsequent to the time it was communicated; or (iii) was developed independently of and without reference to any information of the other Party.
