Ladies and Gentlemen: 

TransAtlantic Petroleum Ltd., a Bermuda exempted company with limited liability (the “Company”), proposes, subject to
the terms and conditions stated in this Placement Agency Agreement (this “Agreement”), to issue and sell an aggregate of 30,357,143 shares (the “Shares”) of the Company’s common shares, $0.01 par value (the
“Common Shares”). The Company hereby confirms its agreement with Madison Williams and Company LLC (“Madison Williams”) and Wunderlich Securities, Inc. (“Wunderlich”), as set forth below. Madison
Williams and Wunderlich are referred to herein collectively as the “Placement Agents” and each individually as a “Placement Agent”. 

1. Agreement to Act as Placement Agents; Delivery and Payment. On the basis of the representations, warranties and
agreements of the Company herein contained, and subject to the terms and conditions set forth in this Agreement: 
 (a) The
Company hereby engages the Placement Agents, as agents of the Company on a non-exclusive basis, to, on a reasonable best efforts basis, solicit offers to purchase the Shares from the Company on the terms and subject to the conditions set forth
herein and in the Prospectus (as defined below). Each Placement Agent agrees, separately and not jointly, to use its reasonable best efforts to assist the Company in obtaining performance by each purchaser of Shares (each, a
“Purchaser”) whose offer to purchase Shares was solicited by such Placement Agent and accepted by the Company, but neither Placement Agent shall, except as otherwise provided in this Agreement, have any liability to the Company in
the event any such purchase is not consummated for any reason. Under no circumstances will either Placement Agent or any of its affiliates be obligated to underwrite or purchase any of the Shares for its own account or otherwise provide any
financing. Each Placement Agent shall act solely as the Company’s agent and not as principal. Neither Placement Agent shall have any authority to bind the Company with respect to any prospective offer to purchase Shares, and the Company shall
have the sole right to accept offers to purchase Shares and may reject any such offer, in whole or 

 
in part. Each Placement Agent has the right, after discussion with the Company, to reject any offer to purchase Shares received by it, in whole or in part, and any such rejection shall not be
deemed a breach of this Agreement. 
 (b) As compensation for services rendered by the Placement Agents hereunder, on the
Closing Date (as defined below), the Company shall pay or cause to be paid to the Placement Agents by wire transfer of immediately available funds to accounts designated by the Placement Agents, an aggregate amount equal to 5.0% of the gross
proceeds received by the Company from the sale of the Shares if consummated prior to the expiration or termination of this Agreement other than gross proceeds of the sale of Shares attributable to N. Malone Mitchell, 3rd or his designated affiliates
(the “Agency Fee”); 0.5% of the Agency Fee will be designated as the “Discretionary Agency Fee” and recipients of the Discretionary Agency Fee will be determined at the sole discretion of the Company; 4.5% of the Agency
Fee will be designated as the “Non-Discretionary Agency Fee”. 55% of the Non-Discretionary Agency Fee shall be paid to Madison Williams, and 25% of the Non-Discretionary Agency Fee shall be paid to Wunderlich. The remaining 20%
of the Non-Discretionary Agency Fee shall be payable by the Company to other parties as to be determined at the sole discretion of the Company. The Placement Agents agree that the foregoing compensation, together with any expense reimbursement
payable hereunder, constitutes all of the compensation that the Placement Agents shall be entitled to receive in connection with the Offering contemplated hereby. 

(c) The Shares are being sold to the Purchasers at the price per Share (the “Purchase Price”) set forth on the cover
page of the Prospectus (as defined below). 
 (d) Prior to the earlier of (i) the date on which this Agreement is
terminated and (ii) the Closing Date, the Company shall not, without the prior written consent of Madison Williams, solicit or accept offers to purchase Common Shares (other than pursuant to the exercise of options or warrants to purchase
Common Shares that are outstanding at the date hereof) otherwise than through the Placement Agents in accordance herewith. 

(e) No Shares shall be deemed to have been purchased and paid for, or sold by the Company, until such Shares shall have been delivered to
the Purchaser purchasing such Shares against payment therefor by such Purchaser. If the Company shall default in its obligations to deliver Shares to a Purchaser whose offer it has accepted, the Company shall indemnify and hold each Placement Agent
harmless against any loss, claim, damage or liability directly or indirectly arising from or as a result of the default by the Company in accordance with the procedures set forth in Section 6(c) hereof. 

(f) Payment of the purchase price for and delivery of the Shares shall be made at a closing (the “Closing”) at the
offices of Bracewell & Giuliani LLP, counsel for the Placement Agents, located at 711 Louisiana Street, Houston, Texas, at 10:00 a.m., New York City time, on September 30, 2010 or at such other time and date as the Placement Agents and
the Company determine pursuant to Rule 15c6-1(a) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (such date of payment and delivery being herein referred to as the “Closing Date”). The
sale of the Shares will be settled through the facilities of The Depository Trust Company’s DWAC system. Concurrently with the execution and delivery of this Agreement, the Company, Madison Williams and Citibank, N.A., as escrow agent (the

  

 2 

 
“Escrow Agent”), shall enter into an escrow agreement (the “Escrow Agreement”), pursuant to which an escrow account (the “Escrow Account”) will
be established for the benefit of the Company and the Purchasers. Subject to the terms hereof and of the Escrow Agreement, payment of the purchase price for the Shares shall be made to the Company in the manner set forth below by federal funds wire
transfer, against delivery of the Shares to such persons and shall be registered in the name or names and shall be in such denominations as Madison Williams may request at least one business day before the Closing Date. Payment of the purchase price
for the Shares to be purchased by Purchasers shall be made by such Purchasers directly to the Escrow Agent and the Escrow Agent shall agree to hold such purchase price in escrow in accordance herewith. Prior to the Closing, each such Purchaser shall
deposit into the Escrow Account an amount (the “Purchase Amount”) equal to the product of (x) the number of Shares such Purchaser has agreed to purchase and (y) the Purchase Price. The aggregate of all such Purchase
Amounts is herein referred to as the “Escrow Funds.” Subject to the terms and conditions hereof and the Escrow Agreement, the Escrow Agent shall, on the Closing Date, deliver to the Company, by federal funds wire transfer, the
Escrow Funds so held by such person in escrow, reduced by an amount equal to the sum of the aggregate Agency Fee payable to Madison Williams (for itself and on behalf of the other Placement Agents) and each Placement Agent’s bona fide estimate
of the amount, if any, of expenses for which such Placement Agent is entitled to reimbursement pursuant hereto. Each of the Company and Madison Williams hereby agree to deliver to the Escrow Agent a Closing Notice in the form attached as Exhibit E
to the Escrow Agreement at least one day prior to the Closing Date. At least one day prior to the Closing Date, each Placement Agent shall submit to the Company its bona fide estimate of the amount, if any, of expenses for which such Placement Agent
is entitled to reimbursement pursuant hereto. As soon as reasonably practicable after the Closing Date, each Placement Agent shall submit to the Company its expense reimbursement invoice and the Company or such Placement Agent, as applicable, shall
make any necessary reconciling payment(s) within thirty days of receipt of such invoices.

adversely to the Company or such subsidiary, would reasonably be likely to result in a Material Adverse Effect. To the Company’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by other
third parties. 
 (w) No Violation. Neither the Company nor any of its subsidiaries is in breach or violation of or in
default (nor has any event occurred which with notice, lapse of time or both would result in any breach or violation of, or constitute a default) (i) under the provisions of its charter or bylaws (or analogous governing instrument, as
applicable) or (ii) in the performance or observance of any term, covenant, obligation, agreement or condition contained in any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license,
lease, contract or other agreement or instrument to which the Company or such subsidiary is a party or by which any of its properties may be bound or affected, or (iii) in the performance or observance of any statute, law, rule, regulation,
ordinance, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or such subsidiary or any of its properties,

conduct its business as described in the Disclosure Package (collectively, “Permits”), and is in compliance in all material respects with the terms and conditions of all such Permits. All such Permits are valid and in full force and
effect. Neither the Company nor any of its subsidiaries has received any notice of any proceedings relating to revocation or modification of, any such Permit, which, individually or in the aggregate, if the subject of an unfavorable decision, ruling
or finding, would have a Material Adverse Effect. Except as may be required under the Securities Act and state and foreign blue sky laws and the rules and regulations of FINRA, no other Permits are required for the Company or any of its subsidiaries
to enter into, deliver and perform this Agreement and to issue and sell the Shares to be issued and sold by the Company hereunder. 

(y) Not an Investment Company. The Company is not or, after giving effect to the offering and sale of the Shares and the
application of the proceeds thereof as described in the Disclosure Package and the Prospectus, will not be (i) required to register as an “investment company” as defined in the Investment Company Act of 1940, as amended (the
“Investment Company Act”), and the rules and regulations of the Commission thereunder or (ii) a “business development company” (as defined in Section 2(a)(48) of the Investment Company Act). 

(z) No Price Stabilization. Neither the Company nor any of its subsidiaries, or any of their respective officers, directors,
affiliates or controlling persons has taken or will take, directly or indirectly, any action designed to or that would be reasonably expected to cause or result in, or which has constituted or which would reasonably be expected to constitute the
stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares. 

(aa) Good Title to Property. The Company and each of its subsidiaries has good and defensible title to all property (whether real
or personal) described in the Registration Statement, the Disclosure Package and the Prospectus as being owned by it, in each case free and clear of all liens, claims, security interests, other encumbrances or defects (collectively,
“Liens”), except (i) such as are described in the Registration Statement, the Disclosure Package and the Prospectus and (ii) those that would not, individually or in the aggregate materially affect the value of such
property and do not materially interfere with the use made and proposed to be made of such property by the Company or any of its subsidiaries. All of the property described in the Registration Statement, Disclosure Package and the Prospectus as
being held under lease by the Company or any of its subsidiaries is held thereby under valid, subsisting and enforceable leases, without any liens, restrictions, encumbrances or claims, except those that, individually or in the aggregate, are
not material and do not materially interfere with the use made and proposed to be made of such property by the Company or such subsidiary. 
  

 12 

 (bb) Intellectual Property Rights. The Company and each of its subsidiaries owns or
possesses the right to use all patents, trademarks, trademark registrations, service marks, service mark registrations, trade names, copyrights, licenses, inventions, software, databases, know-how, Internet domain names, trade secrets and other
unpatented and/or unpatentable proprietary or confidential information, systems or procedures, and other intellectual property (collectively, “Intellectual Property”) necessary to carry on its businesses as currently conducted, and
as proposed to be conducted as described in the Disclosure Package and the Prospectus, and the Company is not aware of any claim to the contrary or any challenge by any other person to the rights of the Company or any of its subsidiaries with
respect to the foregoing except for those that would not reasonably be expected to have a Material Adverse Effect. The Company’s and each of its subsidiaries’ business as now conducted and as proposed to be conducted, to the knowledge of
the Company, does not and will not infringe or conflict with any patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses or other Intellectual Property or franchise right of any person. Neither the Company nor any of its
subsidiaries has received notice of any claim against the Company or any of its subsidiaries alleging the infringement by the Company or any of its subsidiaries of any patent, trademark, service mark, trade name, copyright, trade secret, license in
or other intellectual property right or franchise right of any person. 
 (cc) No Labor Disputes. No labor problem or
dispute with the employees of the Company or any of the Company’s subsidiaries exists, or, to the Company’s knowledge, is threatened or imminent, which would reasonably be expected to result in a Material Adverse Effect. The Company is not
aware that any key employee or significant group of employees of the Company or any of the Company’s subsidiaries plans to terminate employment with the Company or any of the Company’s subsidiaries. Neither the Company nor any of its
subsidiaries has engaged in any unfair labor practice; except for matters which would not, individually or in the aggregate, result in a Material Adverse Effect, (i) there is (A) no unfair labor practice complaint pending or, to the

(dd) Taxes. Except as disclosed in its filings with the Commission, the Company and each of its subsidiaries (i) has timely
filed all necessary federal, state, local and foreign income and franchise tax returns (or timely filed applicable extensions therefor) that have been required to be filed and (ii) is not in default in the payment of any taxes which were
payable pursuant to such returns or any assessments with respect thereto, other than any which the Company or any of its subsidiaries is contesting in good faith and for which adequate reserves

  

 13 

 
have been provided and reflected in the Company’s financial statements included in the Registration Statement, the Disclosure Package and the Prospectus. Except as disclosed in the
Registration Statement, neither the Company nor any of its subsidiaries has any tax deficiency that has been or, to the knowledge of the Company, is reasonably likely to be asserted or threatened against it that would result in a Material Adverse
Effect. Neither the Company nor any of its subsidiaries has engaged in any transaction which is a corporate tax shelter or which could be characterized as such by the Internal Revenue Service or any other taxing authority. 

(ee) ERISA. The Company and each of its subsidiaries is in compliance in all material respects with all presently applicable
provisions of ERISA; no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company or any of its subsidiaries would have any liability; neither the Company
nor any of its subsidiaries has incurred and does not expect to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Internal
Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “pension plan” for which the Company or any of its subsidiaries would have any liability that is
intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification. 

(ff) Compliance with Environmental Laws. The Company and each of its subsidiaries (i) is in compliance with any and all
applicable foreign, federal, state and local laws, orders, rules, regulations, directives, decrees and judgments relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection of human health and safety
or the environment which are applicable to their businesses (“Environmental Laws”); (ii) has received and is in compliance with all permits, licenses or other approvals required of it under applicable Environmental Laws to
conduct its business; and (iii) is in compliance with all terms and conditions of any such permit, license or approval, except where such noncompliance with Environmental Laws, failure to receive required permits, licenses or other approvals or
failure to comply with the terms and conditions of such permits, licenses or approvals would not, individually or in the aggregate, result in a Material Adverse Effect. There are no costs or liabilities associated with Environmental Laws (including,
without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential
liabilities to third parties) which would, individually or in the aggregate, result in a Material Adverse Effect. 
 (gg)
Insurance. The Company and each of its subsidiaries maintains or is covered by insurance provided by recognized, financially sound and reputable institutions with insurance policies in such amounts and covering such risks as is adequate for
the conduct of its business and the value of its properties and as is customary for companies engaged in similar businesses in similar industries. All such insurance is fully in force on the date hereof and will be fully in force as of the Closing
Date. The Company has no reason to believe that it and its subsidiaries will not be able to renew their existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue
its business at a cost that would not have a Material Adverse Effect. Neither the Company nor any of its subsidiaries has been denied any material insurance policy or coverage 

 

 14 

 
for which it has applied. Neither the Company nor any of its subsidiaries insures risk of loss through any captive insurance, risk retention group, reciprocal group or by means of any fund or
pool of assets specifically set aside for contingent liabilities other than as described in the Disclosure Package. 
 (hh)
Accounting Controls. Except as disclosed in the Registration Statement, the Company maintains a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with
management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for
assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and
appropriate action is taken with respect to any differences. 
 (ii) Disclosure Controls. The Company has established,
maintains and evaluates “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), which (i) are designed to ensure that material information relating to the Company and
its subsidiaries is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are
being prepared, (ii) have been evaluated for effectiveness as of the end of the last fiscal period covered by the Registration Statement; and (iii) except as disclosed in the Registration Statement, such disclosure controls and procedures
are effective to perform the functions for which they were established. Except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus, there are no material weaknesses in the design or operation of internal controls
which could adversely affect the Company’s ability to record, process, summarize, or report financial data to management and the Board of Directors of the Company. The Company is not aware of any fraud, whether or not material, that involves
management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in
other factors that could significantly affect internal controls, except any corrective actions with regard to significant deficiencies and material weaknesses. A member of the Audit Committee of the Board of Directors of the Company (the
“Audit Committee”) has confirmed to the Chief Executive Officer, Chief Financial Officer or General Counsel of the Company that, except as set forth in the Disclosure Package, the Audit Committee is not reviewing or investigating,
and neither the Company’s independent auditors nor its internal auditors have recommended that the Audit Committee review or investigate, (i) adding to, deleting, changing the application of or changing the Company’s disclosure with
respect to, any of the Company’s material accounting policies, (ii) any matter which could result in a restatement of the Company’s financial statements for any annual or interim period during the current or prior three fiscal years,
or (iii) a significant deficiency, material weakness, change in internal control over financial reporting or fraud involving management or other employees who have a significant role in the internal control over financial reporting. 

(jj) Minute Books. The minute books of the Company and each of its subsidiaries that would be a Significant Subsidiary have been
made available upon request to the 
  

 15 

 
Placement Agents and counsel for the Placement Agents, and such books (i) contain a complete summary in all material respects of all meetings and actions of the board of directors (including
each board committee) and shareholders of the Company (or analogous governing bodies and interest holders, as applicable), and each of its Significant Subsidiaries since the time of its incorporation or organization through the date of the latest
meeting and action, and (ii) accurately in all material respects reflect all transactions referred to in such minutes. 

(kk) Contracts; Off-Balance Sheet Interests. There is no document, contract, permit or instrument, or off-balance sheet
transaction (including without limitation, any “variable interests” in “variable interest entities,” as such terms are defined in Financial Accounting Standards Board Interpretation No. 46) of a character required by the
Securities Act or the Rules and Regulations to be described in the Registration Statement or the Disclosure Package or to be filed as an exhibit to the Registration Statement or document incorporated by reference therein, which is not described or
filed as required. Each description of a document, contract, permit or instrument in the Registration Statement or the Disclosure Package accurately reflects in all material respects the terms of the underlying document, contract, permit or
instrument. The documents, contracts, permits and instruments described in the immediately preceding sentence to which the Company is a party have been duly authorized, executed and delivered by the Company, constitute valid and binding agreements
of the Company, are enforceable against and by the Company in accordance with the terms thereof (except as rights to indemnity thereunder may be limited by federal or state securities laws and except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity) and are in full force and effect on the date hereof. No default exists, and no event has
occurred which with notice or lapse of time or both would constitute a default, in the due performance and observance of any term, covenant or condition, by the Company or a subsidiary, if a subsidiary is a party thereto, of any agreement or
instrument to which the Company or any of its subsidiaries is a party or by which the Company or its properties or business or a subsidiary or the subsidiary’s properties or business may be bound or affected which default or event, individually
or in the aggregate, would reasonably be expected to have a Material Adverse Effect. 
 (ll) No Undisclosed
Relationships. No relationship, direct or indirect, exists between or among the Company on the one hand and the directors, officers, stockholders, customers or suppliers of the Company or any of their affiliates on the other hand, which is
required to be described in the Registration Statement, the Disclosure Package or the Prospectus or a document incorporated by reference therein and which has not been so described. 

(mm) Brokers Fees. Except as disclosed in the Disclosure Package, there are no contracts, agreements or understandings between the
Company and any person (other than this Agreement) that would give rise to a claim against the Company or the Placement Agents for a brokerage commission, finder’s fee or other like payment in connection with the offering and sale of the
Shares. 
 (nn) Forward-Looking Statements. No forward-looking statements (within the meaning of Section 27A of the
Securities Act and Section 21E of the Exchange Act) contained in either the Disclosure Package or the Prospectus have been made or reaffirmed without a reasonable basis therefor or have been disclosed other than in good faith. 

 

 16

Company’s directors or officers, in their capacities as such, is in compliance in all material respects with all applicable effective provisions of the Sarbanes-Oxley Act and any related rules and regulations promulgated by the Commission. Each

required by Sections 302 and 906 of the Sarbanes-Oxley Act with respect to all reports, schedules, forms, statements and other documents required to be filed by him or her with the Commission. For purposes of the preceding sentence, “principal
executive officer” and “principal financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act. 

(pp) Foreign Corrupt Practices. Neither the Company nor, to the Company’s knowledge, any other person acting on behalf of the
Company, including without limitation any director, officer, agent or employee of the Company or any of its subsidiaries has, directly or indirectly, while acting on behalf of the Company or any of its subsidiaries (i) used any corporate funds
for unlawful contributions, gifts, entertainment or other unlawful expenses relating to political activity or failed to disclose fully any contribution in violation of law, (ii) made any payment to any federal or state governmental officer or

Foreign Corrupt Practices Act of 1977, as amended or (iv) made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment. 

(qq) Affiliate Transactions. There are no transactions, arrangements or other relationships between and/or among the Company, any
of its affiliates (as such term is defined in Rule 405) and any unconsolidated entity, including, but not limited to, any structured finance, special purpose or limited purpose entity that could reasonably be expected to materially affect the
Company’s liquidity or the availability of or requirements for its capital resources required to be described in the Disclosure Package and the Prospectus or a document incorporated by reference therein which have not been described as
required. The Company does not, directly or indirectly, including through any subsidiary, have any outstanding personal loans or other credit extended to or for any of its directors or executive officers. 

(rr) Statistical or Market-Related Data. Any statistical, industry-related or market-related data included or incorporated by
reference in the Registration Statement, the Prospectus or the Disclosure Package, are based on or derived from sources that the Company reasonably and in good faith believes to be reliable and accurate, and such data agree with the sources from
which they are derived.

laundering statutes of all jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering

 17 

 
court or governmental agency, authority or body or any arbitrator involving the Company with respect to the Money Laundering Laws is pending, or to the knowledge of the Company, threatened
against the Company or any of its subsidiaries. 
 (tt) OFAC. Neither the Company nor, to the knowledge of the Company,
any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”);
and the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any affiliate, joint venture partner or other person or entity, which, to the Company’s
knowledge, will use such proceeds for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC. 

(uu) Margin Securities. The Company does not own any “margin securities” as that term is defined in Regulation U of the
Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), and none of the proceeds of the sale of the Shares will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security,
for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might cause any of the Shares to be considered a “purpose credit” within the
meanings of Regulation T, U or X of the Federal Reserve Board. 
 (vv) Rated Securities. At the Time of Sale there were,

(xx) Exchange Act Requirements. The Company has filed in a timely manner all reports required to be filed pursuant to Sections
13(a), 13(e), 14 and 15(d) of the Exchange Act during the preceding 12 months (except to the extent that Section 15(d) requires reports to be filed pursuant to Sections 13(d) and 13(g) of the Exchange Act, which shall be governed by the next
clause of this sentence); and the Company has filed in a timely manner all reports required to be filed pursuant to Sections 13(d) and 13(g) of the Exchange Act, except where the failure to timely file could not reasonably be expected individually
or in the aggregate to have a Material Adverse Effect. 
 (yy) Trading Market. No approval of the shareholders of the
Company under the rules and regulations of any trading market is required for the Company to issue and deliver to the Purchasers the Shares. The Common Shares are registered pursuant to Section 12(b) or

  

 18 

 
12(g) of the Exchange Act and are listed on the NYSE Amex, and the Company has taken no action designed to, or reasonably likely to have the effect of, terminating the registration of the Common
Shares under the Exchange Act or delisting the Common Shares from the NYSE Amex, nor has the Company received any notification that the Commission or the NYSE Amex is contemplating terminating such registration or listing. The Company has complied
in all material respects with the applicable requirements of the NYSE Amex for maintenance of inclusion of the Common Shares thereon. The Company has filed a notification of the listing of the Shares on the NYSE Amex. 

(zz) Reserve Reports. The information underlying the estimates of the reserves of the Company and its subsidiaries, which was

Reports”), including, without limitation, production volumes, sales prices for production, contractual pricing provisions under oil or gas sales or marketing contracts under hedging arrangements, costs of operations and development, and
working interest and net revenue interest information relating to the Company’s ownership interests in properties, was true and correct in all material respects on the dates of such Reserve Reports; the estimates of future capital expenditures

production of the reserves and intervening spot market product price fluctuations incorporated by reference into the Registration Statement, to the knowledge of the Company, there are not any facts or circumstances that would adversely effect the
reserves in the aggregate, or the aggregate present value of future net cash flows therefrom, as incorporated by reference into the Registration Statement and reflected in the Reserve Reports such as to cause a material adverse change; estimates of
such reserves and the present value of the future net cash flows therefrom as incorporated by reference into the Registration Statement and reflected in the Reserve Reports comply in all material respects to the applicable requirements of
Regulations S-K and S-X under the Act. 
 (aaa) Other Information. The Company has not provided and has not authorized

 19 

 3. Covenants. The Company covenants and agrees with the Placement Agent as
follows: 
 (a) Reporting Obligations; Exchange Act Compliance. The Company will file: (i) any Preliminary
Prospectus and the Prospectus with the Commission within the time periods specified by Rule 424(b) and Rules 430A, 430B or 430C under the Securities Act, as applicable, (ii) any Issuer Free Writing Prospectus to the extent required by Rule 433
under the Securities Act, if applicable, (iii) all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act
subsequent to the date of the Prospectus during the Prospectus Delivery Period, and (iv) furnish copies of each Issuer Free Writing Prospectus, if any, (to the extent not previously delivered) to the Placement Agents prior to 11:00 a.m. New
York City time, on the second business day next succeeding the date of this Agreement in such quantities as the Placement Agents shall reasonably request. 

(b) Continued Compliance with Securities Law. If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any
event occurs as a result of which the Disclosure Package as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, the Company will (i) promptly notify the Placement Agents so that any use of the Disclosure Package may cease until it is amended or supplemented and (ii) amend or supplement the
Disclosure Package to correct such statements or omission. If, during the Prospectus Delivery Period, any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Prospectus to
comply with the Securities Act, the Company will (A) promptly notify the Placement Agents of such event and (B) promptly prepare and file with the Commission and furnish, at its own expense, to the Placement Agents and, to the extent
applicable, the dealers and any other dealers upon request of the Placement Agents, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Upon request, the Company will deliver
promptly to the Placement Agents such number of the following documents as the Placement Agents shall reasonably request: (i) conformed copies of the Registration Statement as originally filed with the Commission (in each case excluding
exhibits), (ii) any Preliminary Prospectus, (iii) any Issuer Free Writing Prospectus, (iv) the Prospectus (the delivery of the documents referred to in clauses (i), (ii) (iii) and (iv) of this subsection (b) to
be made not later than 10:00 a.m., New York time, on the business day following the date of request), (v) conformed copies of any amendment to the Registration Statement (excluding exhibits), (vi) any amendment or supplement to the
Disclosure Package or the Prospectus (the delivery of the documents referred to in clauses (v) and (vi) of this subsection (b) to be made not later than 10:00 a.m., New York City time, on the business day following the
date of request) and (vii) any document incorporated by reference in the Disclosure Package or the Prospectus (excluding exhibits thereto) (the delivery of the documents referred to in clause (vii) of this subsection (b) to be
made not later than 10:00 a.m., New York City time, on the business day following the date of request). 
  

 20 

 (c) Issuer Free Writing Prospectuses. The Company will (i) not make any offer
relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the Company with the
Commission under Rule 433 under the Securities Act unless Madison Williams approves its use in writing prior to first use (each, a “Permitted Free Writing Prospectus”); provided, that the prior written consent of Madison
Williams shall be deemed to have been given in respect of any electronic road show; (ii) treat each Permitted Free Writing Prospectus prepared or approved by the Company as an Issuer Free Writing Prospectus; (iii) comply with the
requirements of Rules 164 and 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including the requirements relating to filing timely with the Commission, legending and record keeping; and (iv) not take any action
that would result in the Placement Agents or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Placement Agents that the Placement Agents
otherwise would not have been required to file thereunder. The Company and the Placement Agents, as applicable, will satisfy the conditions in Rule 433 under the Securities Act to avoid a requirement to file with the Commission any electronic road
show. 
 (d) Conflicting Issuer Free Writing Prospectus. If at any time following the issuance of an Issuer Free Writing
Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement relating to the Shares or included or
would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the
Company promptly will notify the Placement Agents and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing sentence does not
apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company by a Placement Agent specifically for inclusion therein, which information the parties
hereto agree is limited to the Placement Agents’ Information. 
 (e) Blue Sky Laws. The Company will promptly take
or cause to be taken, from time to time, such actions as the Placement Agents may reasonably request to qualify the Shares for offering and sale under the state securities, or blue sky, laws of such states or other jurisdictions as the Placement
Agents may reasonably request and to maintain such qualifications in effect so long as the Placement Agents may request for the distribution of the Shares, provided, that in no event shall the Company be obligated to qualify as a foreign
corporation in any jurisdiction in which it is not so qualified or to file a general consent to service of process in any jurisdiction or subject itself to taxation as doing business in any jurisdiction. The Company will advise the Placement Agents
promptly of the suspension of the qualification or registration of (or any exemption relating to) the Shares for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of

Securities Act and the Rules and Regulations (including, at the option of the Company, Rule 158). For the purpose of the preceding sentence, “as soon as practicable” means the 45th day after the end of the fourth fiscal quarter following

communication is required by law.

transfer, pledge, contract to sell, or otherwise dispose of, or announce the intention to otherwise dispose of, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares, not to engage in any swap, hedge
or similar agreement or arrangement that transfers, in whole or in part, directly or indirectly, the economic risk of ownership of Common Shares or any such securities and not to engage in any short selling of any Common Shares or any such

registration statement for the resale of securities of the Company.
 4. Costs and Expenses. The Company, whether
or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or reimburse the Placement Agents for all actual and accountable direct and reasonable expenses incident to the performance of this Agreement
and in connection with the transactions contemplated hereby, including the reasonable legal fees and expenses of counsel to the Placement Agents. 

5. Conditions of Placement Agents’ Obligations. The obligations of the Placement Agents hereunder and Closing of the

effectiveness of the Registration Statement or any part thereof, preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus or any part thereof shall have been issued under the Securities Act and no proceedings for that
purpose or pursuant to Section 8A under the Securities Act shall have been initiated or threatened by the Commission, (ii) no order suspending the qualification or registration of the Shares under the securities or blue sky laws of any
jurisdiction shall be in effect and (iii) all requests for additional information on the part of the Commission (to be included or incorporated by reference in the Registration Statement, the Disclosure Package, the Prospectus or any Issuer
Free Writing Prospectus or otherwise) shall have been complied with to the reasonable satisfaction of the Placement Agents. On or prior to the Closing Date, the Registration Statement or any amendment thereof or supplement thereto shall not contain
an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and neither the Disclosure Package, nor any Issuer Free Writing Prospectus nor the

circumstances in which they were made, not misleading. 
 (c) Action Preventing Issuance. No action shall have been taken
and no law, statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would prevent the issuance or sale of the Shares or materially and adversely affect or would reasonably be expected to

outstanding Common Shares due to the issuance of shares upon the exercise of outstanding options or warrants or the conversion of convertible indebtedness), or material change in the short–term debt or long–term debt of the Company (other
than upon conversion of convertible indebtedness) or any material adverse change, in or affecting the business, assets, general affairs, management, financial position, prospects, stockholders’ equity or results of operations of the Company,
otherwise than as set forth in the Disclosure Package, the effect of which, in any such case described in clause (i) or (ii) of this subsection (d), is, in the reasonable judgment of the Placement Agents, so material and adverse as
to make it impracticable or inadvisable to proceed with the sale or delivery of the Shares on the terms and in the manner contemplated in the Disclosure Package. 

(e) Representations and Warranties. Each of the representations and warranties of the Company contained herein shall be true and
correct when made and on and as of the Closing Date, as if made on such date (except that those representations and warranties

(ii) there has not been, subsequent to the date of the most recent audited financial statements included or incorporated by reference in

 6. Indemnification
and Contribution. 
 (a) Indemnification of the Placement Agents. The Company agrees to indemnify, defend and
hold harmless each Placement Agent, its affiliates, each of its directors, officers, members, employees, representatives and agents and any person who controls a Placement Agent within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act (each a “Control Person”), and the successors and assigns of all of the foregoing persons, from and against any losses, claims, damages, expenses or liabilities, joint or several, to which such
person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise (including in settlement of any litigation if such settlement is effected with the written
consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration
Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or in any materials or information provided to Purchasers by, or with the approval of, the
Company in connection with the marketing of the offering of the Common Shares (“Marketing Materials”), including any roadshow or investor presentations made to Purchasers by the Company (whether in person or electronically) or arise
out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such person for any legal or other expenses
reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability, expense or action; or (ii) in whole or in part upon any inaccuracy in the representations

  

 27 

 
and warranties of the Company contained herein; or (iii) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; provided, however, that
the Company shall not be liable in any such case to the extent that any such loss, claim, damage, expense, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the
Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any such amendment or supplement, any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with written
information furnished to the Company by a Placement Agent or its representatives or agents, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Placement Agents’ Information. 

(b) Indemnification of the Company. Each Placement Agent, severally and not jointly, agrees to indemnify, defend and hold harmless
the Company, its affiliates, each of its directors, officers, members, employees, representatives and agents and any Company Control Person against any losses, claims, damages, expenses or liabilities to which the Company may become subject, under
the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the applicable Placement
Agent), insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any
Preliminary Prospectus, the Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus or Marketing Materials, or arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was
made in the Registration Statement, any Preliminary Prospectus, the Disclosure Package, the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus or Marketing Materials in reliance upon and in conformity with
written information furnished to the Company by such Placement Agent or its representatives or agents, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Placement Agents’ Information,
and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action. Notwithstanding the provisions of this
Section 6(b), in no event shall any indemnity by either Placement Agent under this Section 6(b) exceed the total compensation received by such Placement Agent in accordance with Section 1(b) hereof. 

(c) Notice and Procedures. If any action, suit or proceeding (each, a “Proceeding”) is brought against a person
(an “Indemnified Party”) in respect of which indemnity may be sought against the Company or a Placement Agent (as applicable, the “Indemnifying Party”) pursuant to subsections (a) or
(b) above, respectively, of this Section 6, such Indemnified Party shall promptly notify such Indemnifying Party in writing of the institution of such Proceeding and such Indemnifying Party shall assume the defense of such
Proceeding, including the employment of counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the Indemnifying Party) and payment of all fees and expenses;
provided, however, that the omission to so notify such Indemnifying Party shall not relieve such Indemnifying Party from any liability 

 

 28 

 
which such Indemnifying Party may have to any Indemnified Party or otherwise, except to the extent the Indemnifying Party has been materially prejudiced by such failure; and provided,
further, that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under subsection (a) or (b) above. The Indemnified Party or
Parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless (i) the employment of such counsel shall have been
authorized in writing by the Indemnifying Party in connection with the defense of such Proceeding, (ii) after having received notice from the Indemnified Party the Indemnifying Party shall not have, within a reasonable period of time in light
of the circumstances, employed counsel to defend such Proceeding or (iii) such Indemnified Party or Parties shall have reasonably concluded upon written advice of counsel that there may be one or more legal defenses available to it or them
which are different from, additional to or in conflict with those available to such Indemnifying Party (in which case such Indemnifying Party shall not have the right to direct that portion of the defense of such Proceeding on behalf of the
Indemnified Party or Parties, but such Indemnifying Party or Parties may employ counsel and participate in the defense thereof but the reasonable fees and expenses of such counsel shall be at the expense of the Indemnifying Party), in any of which
events such reasonable fees and expenses shall be borne by such Indemnifying Party and paid as incurred (it being understood, however, that such Indemnifying Party shall not be liable for the expenses of more than one separate counsel (in addition
to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the Indemnified Parties who are parties to such Proceeding). An Indemnifying Party shall not be liable for any settlement of any
Proceeding effected without its written consent but, if settled with its written consent, such Indemnifying Party agrees to indemnify and hold harmless the Indemnified Party or parties from and against any loss or liability by reason of such
settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Party shall have requested an Indemnifying Party to reimburse the Indemnified Party for fees and expenses of counsel as contemplated by the second sentence of this
Section 6(c), then the Indemnifying Party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such
Indemnifying Party of the aforesaid request, (ii) such Indemnifying Party shall not have fully reimbursed the Indemnified Party in accordance with such request prior to the date of such settlement, (iii) such Indemnified Party shall have
given the Indemnifying Party at least 30 days’ prior notice of its intention to settle and (iv) such settlement includes an unconditional release of the Indemnifying Party from all liability on claims that are the subject matter of
such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of the Indemnifying Party; provided, however, that this sentence shall not apply if the fees and expenses are reasonably in dispute. No
Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding in respect of which any Indemnified Party is or could
have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such
Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such Indemnified Party. 

(d) Contribution. If the indemnification provided for in this Section 6 is unavailable to an Indemnified Party under
subsections (a) or (b) of this Section 6 or insufficient 
  

 29 

 
to hold an Indemnified Party harmless in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages, liabilities or expenses referred to in subsections (a) or (b) above, (i) in such
proportion as is appropriate to reflect the relative benefits received by the Indemnifying Party or Parties on the one hand and the Indemnified Party or Parties on the other hand from the offering of the Shares or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Indemnifying Party or
Parties on the one hand and the Indemnified Party or Parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand and the Placement Agents on the other hand shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares (before
deducting expenses) received by the Company bear to the discounts and commissions received by the Placement Agents. The relative fault of the Company on the one hand and the Placement Agents on the other hand shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Placement Agents, on the
other hand, and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written
information furnished to the Company by the Placement Agents for use in the Registration Statement, Disclosure Package, Issuer Free Writing Prospectus, the Prospectus or Marketing Materials, or in any amendment or supplement thereto, consists solely
of the Placement Agents’ Information. 
 (e) Allocation. The Company and the Placement Agents agree that it would
not be just and equitable if contribution pursuant to subsection (d) above were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the
first sentence of subsection (d) above. Notwithstanding the provisions of this Section 6(e), neither Placement Agent shall be required to contribute any amount in excess of the total commissions received by such Placement
Agent in accordance with Section 1(b) less the amount of any damages which such Placement Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged
act or failure to act or alleged failure to act. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity. 

(f) Representations and Agreements to Survive Delivery. The obligations of the Company under this Section 6 shall be
in addition to any liability which the Company may otherwise have. The indemnity and contribution agreements contained in this Section 6 and the covenants, agreements, warranties and representations of the Company and the Placement
Agents contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the

  

 30 

 
Placement Agents, any person who controls either Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or any affiliate of
either Placement Agent, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and (iii) the
issuance and delivery of the Shares. The Company and each Placement Agent agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors
in connection with the issuance and sale of the Shares, or in connection with the Registration Statement, the Disclosure Package or the Prospectus. 

7. Information Furnished by Placement Agent. 

(a) The Company acknowledges that the statements set forth in the first paragraph with respect to each Placement Agent’s name under
the heading “Plan of Distribution” in the Prospectus (the “Placement Agents’ Information”) constitute the only information relating to the Placement Agents furnished in writing to the Company by the Placement Agents
as such information is referred to in Sections 2 and 6 hereof. 
 (b) Each Placement Agent agrees and confirms
that it has not provided any Purchaser or its respective agents or counsel with any information about the Company that constitutes or might constitute material, non-public information which is not otherwise disclosed in the Disclosure Package.

 8. Termination. The Placement Agents shall have the right to terminate this Agreement by giving notice
as hereinafter specified at any time at or prior to the Closing Date, without liability on the part of the Placement Agents to the Company, if (i) prior to delivery and payment for the Shares (A) trading in securities generally shall have
been suspended on or by the New York Stock Exchange, the New York Stock Exchange Amex Equities, the NASDAQ Global Market or in the over the counter market (each, a “Trading Market”), (B) trading in the Common Shares of the
Company shall have been suspended on any exchange, in the over-the-counter market or by the Commission, (C) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities or a material
disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States, (D) there shall have occurred any outbreak or material escalation of hostilities or acts of terrorism involving the United
States or there shall have been a declaration by the United States of a national emergency or war, (E) there shall have occurred any other calamity or crisis or any material change in general economic, political or financial conditions in the
United States or elsewhere, if the effect of any such event specified in clause (D) or (E), in the judgment of the Placement Agents, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of
and payment for the Shares on the Closing Date on the terms and in the manner contemplated by this Agreement, the Disclosure Package and the Prospectus, (ii) since the time of execution of this Agreement or the earlier respective dates as of
which information is given in the Disclosure Package or incorporated by reference therein, there has been any Material Adverse Effect, (iii) the Company shall have failed, refused or been unable to comply with the terms of or perform any
agreement or obligation under this Agreement, other than by reason of a default by the Placement Agents, or (iv) any condition of the Placement Agents’ obligations hereunder is not fulfilled. Any such

  

 31 

 
termination shall be without liability of any party to any other party except that the provisions of Section 4, Section 6, and Section 12 hereof shall at all
times be effective notwithstanding such termination. The Company may, at its option, terminate this Agreement at any time prior to the Time of Sale upon giving notice as hereinafter specified without liability on the part of the Company to the
Placement Agents if the Placement Agents fail to comply in any material respect with any of their obligations hereunder.

Agents. 
 11. Governing Law; Submission to Jurisdiction. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York, without giving effect to the conflicts of laws provisions thereof. Except as set forth below, no Proceeding may be commenced, prosecuted or continued in any court other than the courts
of State of New York located in the City and County of New York or the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company hereby consents to
the jurisdiction of such courts and personal service with respect thereto. The Company and each Placement Agent hereby consent to personal jurisdiction, service and venue in any court in which any Proceeding arising out of or in any way relating to
this Agreement is brought by any third party against the Placement Agents. The Company and each Placement Agent hereby waive all right to trial by jury in any Proceeding (whether based upon contract, tort or otherwise) in any way arising out of or

enforced in any other courts in the jurisdiction of which the Company is or may be subject, by suit upon such judgment. 
 12.
No Fiduciary Relationship. The Company hereby acknowledges and agrees that: 
 (a) No Other Relationship.
Each Placement Agent has been retained solely to act as Placement Agent on a non-exclusive basis in connection with the offering of the Company’s securities. The Company further acknowledges that each Placement Agent is acting pursuant to a
contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that either Placement Agent act or be responsible as a fiduciary to the Company, its management, stockholders,
creditors or any other person in connection with any activity that such Placement Agent may undertake or has undertaken in furtherance of the offering of the Company’s securities, either before or after the date hereof, irrespective of whether
such Placement Agent has advised or is advising the 
  

 33 

 
Company on other matters. Each Placement Agent hereby expressly disclaims any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this
Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. 

(b) Arm’s-Length Negotiations. The price of the Shares determined hereunder were or will be established by the Company
following discussions and arms-length negotiations with the Purchasers and the Placement Agents, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions
contemplated by this Agreement. 
 (c) Absence of Obligation to Disclose. The Company has been advised that each
Placement Agent and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that neither Placement Agent has any obligation to disclose such interests or transactions to the
Company by virtue of any fiduciary, advisory or agency relationship. 
 (d) Waiver. The Company hereby waives and
releases, to the fullest extent permitted by law, any claims that the Company may have against either Placement Agent with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions
contemplated by this Agreement or any matters leading up to such transactions and agrees that neither Placement Agent shall have any liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim to any person
asserting a fiduciary duty claim on behalf of the Company, including stockholders, employees or creditors of the Company. 
 13.
Headings. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement. 

14. Amendments and Waivers. No supplement, modification or waiver of this Agreement shall be binding unless executed in
writing by the party or parties to be bound thereby. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall
be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided. 

15. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart,
the executed counterparts shall each be deemed to be an original and all such counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart by facsimile or portable document format (.pdf) or of a similar
format shall be effective as delivery of a manually executed counterpart thereof. 
 16. Research Analyst
Independence. The Company acknowledges that the Placement Agents’ research analysts and research departments are required to be independent from their investment banking divisions and are subject to certain regulations and internal
policies, and that the Placement Agents’ research analysts may hold views and make statements or investment 
  

 34 

 
recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their investment banking divisions. The Company hereby waives and
releases, to the fullest extent permitted by law, any claims that the Company may have against either Placement Agent with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts
and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Placement Agent’s investment banking division. The Company acknowledges that each Placement Agent is a full service
securities firm and as such from time to time, subject to applicable securities laws, rules and regulations, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of
the Company; provided, however, that nothing in this Section 16 shall relieve the Placement Agents of any responsibility or liability it may otherwise bear in connection with activities in violation of applicable securities
laws, rules or regulations. 
 17. Entire Agreement. This Agreement constitutes the entire agreement of the
parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. 

18. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph, clause or provision of this
Agreement shall not affect the validity or enforceability of any other section, paragraph, clause or provision hereof. If any section, paragraph, clause or provision of this Agreement is for any reason determined to be invalid or unenforceable,
there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable. 

19. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

SUBSCRIPTION ESCROW AGREEMENT 

among 

TRANSATLANTIC PETROLEUM LTD., 

MADISON WILLIAMS AND COMPANY LLC, 

and 

CITIBANK, N.A., as Escrow Agent 

Dated as of September 27, 2010 

 This Subscription Escrow Agreement (this “Agreement”), dated as of
September 27, 2010, is entered into by and among TransAtlantic Petroleum Ltd., a Bermuda corporation (the “Company”), Madison Williams and Company LLC (“Madison Williams”), as the lead placement
agent for itself and on behalf of the Company’s other placement agents in the Offering (as defined below) (collectively Madison Williams and the other placement agents are referred to herein as the “Placement Agents”),
and CITIBANK, N.A., a national banking association incorporated under the laws of the United States of America (the “Escrow Agent”). 

WHEREAS, the Company intends to raise cash funds from investors (the “Investors”) pursuant to a “registered
direct” public offering (the “Offering”) of not less than $50,000,000 (the “Minimum Amount”) nor more than $100,000,000 of common shares, par value $0.01 per share (each, a
“Share”), on a “best efforts” basis; 
 WHEREAS, the Company has entered into a Placement
Agency Agreement, dated September 27, 2010, with the Placement Agents pursuant to which the Placement Agents are authorized to solicit subscription funds on behalf of the Company in connection with the Offering; 

WHEREAS, the Company and Madison Williams desire to establish an escrow account with the Escrow Agent into which the Company and the
Placement Agents shall instruct Investors to deposit funds, to be held for the benefit of the Investors and the Company, until such time as such funds are to be released to the Company or returned to the Investors in accordance with the terms of
this Agreement; 
 WHEREAS, the Escrow Agent is willing to accept appointment as escrow agent upon the terms and conditions set
forth herein; and 
 WHEREAS, unless the Offering has been terminated by the Company and Madison Williams, or the Minimum Amount
has not been deposited with the Escrow Agent and accepted by the Company, the closing of the Offering shall take place on or before 4:00 p.m. eastern time on September 30, 2010 (the “Initial Closing Date”), unless
otherwise extended to a date following the Initial Closing Date by the Company and Madison Williams as provided herein. 
 NOW,
THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged by each of the parties hereto, the parties hereto, intending to be legally bound, do hereby agree as follows: 

1. Establishment of Escrow. Prior to the commencement of the Offering, the Escrow Agent shall cause to be opened a fully
segregated non-interest bearing account (the “Escrow Account”). The Company and Madison Williams hereby appoint CITIBANK, N.A. as Escrow Agent in accordance with the terms and conditions set forth herein, and the Escrow Agent
hereby accepts such appointment. The Escrow Agent hereby agrees to receive and disburse the proceeds from the offering of the Shares in accordance with the terms and conditions set forth herein. The Escrow Account shall be entitled “Escrow
Account for the benefit of Subscribers for Shares of TransAtlantic Petroleum Ltd.” 

 2. Deposit of Escrowed Property. 

(a) The Company and the Placement Agents shall instruct Investors to direct any amounts wired in payment for Shares to the Escrow Agent
for deposit into the Escrow Account, in accordance with the wire instructions provided for the Escrow Agent in Section 7 hereof. Upon receipt thereof, the Escrow Agent shall credit such funds to the Escrow Account. During any period
prior to the closing of the Offering, the Company is aware and understands that it is not entitled to the assets held in the Escrow Account (the “Escrow Property”) and no Escrow Property shall become the property of the
Company or any other entity, or be subject to the debts of the Company or any other entity, until properly released by the Escrow Agent to the Company in accordance with this Agreement. All proceeds so deposited shall remain the property of the
Investors and shall not be subject to any liens or charges by the Company, the Placement Agents or the Escrow Agent until properly released by the Escrow Agent to the Company and Madison Williams in accordance with this Agreement. 

(b) Upon receipt of the Escrow Property, the Escrow Agent shall acknowledge such receipt in writing (which may be via electronic mail) to
the Company and Madison Williams and shall hold and disburse the same pursuant to the terms and conditions of this Agreement. The Escrow Agent shall have no duty to verify whether the amounts and property delivered comport with the requirements of
any other agreement. 
 (c) The Escrow Agent will reject any Investor’s funds upon receipt of written instructions
generated as a result of the Company’s or Madison Williams’ review of the Investor’s suitability for investment in the Shares. If the Company’s or Madison Williams’ review of the Investor’s application and method for
payment for Shares under its anti-money laundering policies and procedures indicates a risk of money laundering or fraud, the Company or Madison Williams will notify the Escrow Agent and will provide written instructions regarding disposition of the
Investor funds in question. The Escrow Agent shall be entitled to rely on the foregoing review by the Company or Madison Williams, and in the absence of such written instructions from the Company or Madison Williams, the Escrow Agent shall be
entitled to conclude that no risk of money laundering or fraud exists; provided, however, that the Escrow Agent (without undertaking any independent or additional responsibility for diligence or review) reserves the right to reject Investor funds
based on its own policies and procedures and determinations by providing notice to the Company and Madison Williams. 
 (d) The
Escrow Property will remain uninvested and no interest will accrue thereon. 
 3. Maintenance of Escrowed Property.
Pursuant to this Agreement, and during the term of this Agreement, the Escrow Agent shall maintain the assets of the Escrow Property in the Escrow Account. 

4. Instructions, Verification, Communications. 

(a) All instructions required under this Agreement will be delivered to the Escrow Agent in writing in English, in facsimile form and, if
so requested by the Escrow Agent, an original, executed by any person who is authorized by the Company and Madison Williams to provide such instructions (“Authorized Persons”), which Authorized Persons may include officers of
the Company and Madison Williams. In addition, any notices to be given by or to the 
  

 2 

 
Company or Madison Williams pursuant to this Agreement may be given by or to any Authorized Person. The identity of such Authorized Persons, as well as their specimen signatures, title, telephone
and e-mail address, shall be delivered to the Escrow Agent in the list of authorized signers form set forth on Exhibit A, and shall remain in effect until the Company or Madison Williams notify the Escrow Agent of any change. The Escrow
Agent, the Company, Madison Williams and all Authorized Persons identified to the Escrow Agent as provided herein agree that the above constitutes a commercially reasonable security procedure. 

(b) In the event funds transfer instructions are given (other than in writing at the time of execution of this Agreement), whether in
writing, by telecopier, .pdf, e-mail, or otherwise, such funds transfer instructions should contain a selected test word also evidenced on Exhibit A. Test Words must contain at least 8 alphanumeric characters, established at document
execution and changed each time Exhibit A is updated in accordance with (a) above. In addition or in lieu of test words, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call back to the applicable
person(s) specified to the Escrow Agent from time to time by an Authorized Person and the Escrow Agent may rely upon the confirmations of anyone purporting to be the person(s) so designated. To ensure the accuracy of the instructions it receives,
the Escrow Agent may record such call backs. If the Escrow Agent is unable to verify the instruction, or is not satisfied in its sole discretion with the verification it receives, it will not execute the instruction until all issues have been
resolved to its satisfaction. The persons and telephone numbers for call backs may be changed only in writing, signed by an Authorized Person, actually received and acknowledged by the Escrow Agent. The Company, Madison Williams and all Authorized
Persons identified to the Escrow Agent acknowledge that these security procedures for funds transfers are commercially reasonable. 

(c) To help the U.S. government fight the funding of terrorism and money laundering activities, Federal law requires all financial
institutions to obtain, verify, and record information that identifies each person who opens an account. When an account is opened, the Escrow Agent will ask for information that will allow the Escrow Agent to identify relevant parties. The Company,
Madison Williams and all Authorized Persons identified to the Escrow Agent hereby acknowledge such information disclosure requirements and agree to comply with all such information disclosure requests from time to time from the Escrow Agent.

 (d) Notwithstanding anything to the contrary herein, any and all email communications (both text and attachments) by or from
the Escrow Agent that the Escrow Agent deems to contain confidential, proprietary, and/or sensitive information shall be encrypted. The recipient (the “Email Recipient”) of the
encrypted email communication will be required to complete a registration process. Instructions on how to register and/or retrieve an encrypted message will be included in the first secure email sent by the Escrow Agent to the Email Recipient.
Additional information and assistance on using the encryption technology can be found at Citibank’s Secure Email website at www.citigroup.com/citigroup/citizen/privacy/email.htm or by calling (866) 535-2504 (in the U.S.) or
(904) 954-6181. 
 (e) The provisions of this Section 4(a)-(d) may be amended by the Escrow Agent unilaterally
upon notice to the Company and Madison Williams.

 5. List of Investors. The Company and Madison Williams shall furnish or cause to be
furnished to the Escrow Agent a list, substantially in the form of Exhibit B attached, containing the name of, the address of, number of Shares subscribed for by, the subscription amount delivered to the Escrow Agent on behalf of, and the
U.S. tax identification number, if applicable, of, each Investor whose funds are being deposited (the “List of Investors”), and to which is attached a completed W-9 form (or, in the case of any Investor who is not a United
States citizen or resident, a W-8 form) for each listed Investor. The Escrow Agent shall notify the Company and Madison Williams of any discrepancy between the subscription amounts set forth on the List of Investors delivered pursuant to this
Section 5 and the subscription amounts received by the Escrow Agent, whereupon the Company and Madison Williams shall resolve such discrepancy, and the Company and Madison Williams shall cause to be delivered to the Escrow Agent a
revised List of Investors reflecting such resolution. 
 6. Release of Subscription Amounts. 

(a) If the Escrow Agent shall receive a notice, substantially in the form of Exhibit C hereto (an “Offering Termination
Notice”), from the Company, the Escrow Agent shall promptly after receipt of such Offering Termination Notice send to each Investor listed on the current List of Investors held by the Escrow Agent pursuant to Section 5, a
check to the order of such Investor in the amount of the subscription amount held by the Escrow Agent for such Investor as set forth on such List of Investors held by the Escrow Agent. The Escrow Agent shall promptly notify the Company and Madison
Williams of the distribution of such funds to the Investors. 
 (b) If prior to 4:00 P.M. eastern time on the Initial Closing
Date, the Escrow Agent receives written notice, in the form of Exhibit D, signed by the Company and Madison Williams stating that the closing of the Offering has been extended to a date following the Initial Closing Date (the
“Extended Closing Date”) then the closing of the Offering shall be so extended. 
 (c) In the event that
(i) funds equal to at least the Minimum Amount have been deposited with the Escrow Agent in accordance with this Agreement on or before the Initial Closing Date or the Extended Closing Date, as the case may be (each, a “Closing
Date”), and (ii) no Offering Termination Notice shall have been received by the Escrow Agent, the Company and Madison Williams shall deliver to the Escrow Agent a joint notice on such Closing Date substantially in the form of
Exhibit E hereto (the “Closing Notice”), designating the proceeds which are to be distributed on such Closing Date, and identifying the Investors and the number of Shares to be sold to each thereof on such Closing
Date. The Escrow Agent, after receipt of the Closing Notice, on the Initial Closing Date or the Extended Closing Date, as the case may be, shall pay to the Company and Madison Williams (for itself and the other Placement Agents) the amount set forth
for each such entity, respectively, on the Closing Notice, by wire transfer of immediately available funds and otherwise in the manner specified in the Closing Notice, which amounts shall equal collectively the aggregate of the subscription amounts
paid by the Investors identified in the Closing Notice for the Shares to be sold on such Closing Date as set forth on the List of Investors held by the Escrow Agent pursuant to Section 5. 

(d) If at any time and from time to time prior to the release of any Investor’s total subscription amount pursuant to paragraph
(a) or (c) of this Section 6 from the Escrow Account, the Company shall deliver to the Escrow Agent a notice, substantially in the form of Exhibit F hereto (a “Subscription Termination Notice”),
to the effect that any or all of the subscriptions of such Investor have been rejected by the Company (a “Rejected Subscription”), the Escrow Agent shall, promptly after receipt of such Subscription Termination Notice, send a
check to the order of such Investor in the amount of such Rejected Subscription. 
  

 4 

 (e) If by 4:00 P.M. eastern time on Initial Closing Date or the Extended Closing Date, if
extended pursuant to paragraph (b) of this Section 6, the Escrow Agent has not received a Closing Notice or the total amount of funds that have been deposited with the Escrow Agent is less than the Minimum Amount, then the Escrow
Agent shall promptly send to each Investor a check to the order of such Investor in the amount of the subscription amount held by the Escrow Agent for such Investor as set forth on the List of Investors. 

(f) For the purposes of this Section 6, any check that the Escrow Agent shall be required to send to any Investor shall be
sent to such Investor within 3-5 business days by first class mail, postage prepaid, at the address set forth on the List of Investors. 

7. Notices and Wire Instructions. 

(a) Any notice or other communication required or permitted to be given hereunder shall be in writing in English and shall be sent

8. Concerning the Escrow Agent. Each party agrees that: 

(a) The Escrow Agent shall not be under any duty to give the Escrow Property held by it hereunder any greater degree of care than it
gives its own similar property, and shall not be required to invest any funds held hereunder. Uninvested funds held hereunder shall not earn or accrue interest. 

(b) The duties, responsibilities and obligations of the Escrow Agent shall be limited to those expressly set forth herein and no duties,
responsibilities or obligations shall be inferred or implied. The Escrow Agent shall not be subject to, nor required to comply with, any other agreement between or among any or all of the Company and Madison Williams or to which any of them may be a
party and to which the Escrow Agent is not a party, nor required to comply with any direction or instruction that is not delivered to the Escrow Agent in accordance with this Agreement. The Escrow Agent shall not be required to expend or risk any of
its own funds or otherwise incur any financial or other liability in the performance of any of its duties hereunder. The Escrow Agent shall not be obligated to take any legal or other action hereunder which might in its judgment involve or cause it
to incur any expense or liability unless it shall have been furnished with acceptable indemnification. Notwithstanding any other provision hereof, the Escrow Agent shall have no responsibility whatsoever for any Shares, and the Escrow Agent shall
have no duty to disburse any funds deposited with it by check until such check shall have cleared. 
  

 6 

 (c) The Escrow Agent shall not be liable for any action taken or omitted or for any loss or
injury resulting from its actions or its performance or lack of performance of its duties hereunder in the absence of gross negligence or willful misconduct on its part. In no event shall Escrow Agent be liable (i) for acting in accordance with
or relying upon any order, judgment, instruction, notice, demand, certificate, instrument, consent, authorization, receipt, power of attorney, e-mail, .pdf or writing from the Company or Madison Williams or any entity acting on its behalf that is
delivered to the Escrow Agent in accordance with this Agreement, or (ii) for any indirect, consequential, punitive or special damages, regardless of the form of action and whether or not any such damages were foreseeable or contemplated.

 (d) The Escrow Agent shall not incur any liability for not performing any act or fulfilling any duty, obligation or
responsibility hereunder by reason of any occurrence beyond the control of Escrow Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God, terrorism, war, or the
unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility). 
 (e) If at any time the
Escrow Agent is served with any judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process which in any way affects the Escrow Property (including but not limited to orders of attachment or
garnishment or other forms of levies or injunctions or stays relating to the transfer of the Escrow Property), the Escrow Agent is authorized to comply therewith in any manner it or legal counsel of its own choosing deems appropriate; and if the
Escrow Agent complies with any such judicial or administrative order, judgment, decree, writ or other form of judicial or administrative process, the Escrow Agent shall not be liable to any of the parties hereto or to any other person or entity even
though such order, judgment, decree, writ or process may be subsequently modified or vacated or otherwise determined to have been without legal force or effect. The Escrow Agent shall have no duty to determine the authenticity or the correctness of
any fact stated therein or the propriety or validity or the service thereof. 
 (f) The Escrow Agent may act pursuant to the
advice of counsel with respect to any matter relating to this Agreement and shall not be liable for any action taken or omitted in good faith and in accordance with such advice. 

(g) The Escrow Agent does not have any interest in the Escrow Property deposited hereunder but is serving as escrow holder only and
having only possession thereof. The Company shall pay or reimburse the Escrow Agent upon request for any transfer taxes or other taxes relating to the Escrow Property incurred in connection herewith and shall indemnify and hold harmless the Escrow
Agent from any amounts that it is obligated to pay in the way of such taxes. Any payments of income from this Escrow Account shall be subject to withholding regulations then in force with respect to United States taxes. The Company and Madison
Williams will provide the Escrow Agent with appropriate W-9 forms for tax I.D., number certifications, or W-8 forms for non-resident alien certifications. 
  

 7 

 (h) Paragraphs (c) and (g) shall survive notwithstanding any termination of this
Agreement or the resignation or removal of the Escrow Agent. 
 (i) The Escrow Agent shall not be responsible in any respect for
the form, execution, validity, sufficiency, value or genuineness of documents or securities deposited hereunder, or for any description therein, or for the identity, authority or rights of persons executing or delivering or purporting to execute or
deliver any such document, security or endorsement. The Escrow Agent shall not be called upon to advise any party as to the wisdom in selling or retaining or taking or refraining from any action with respect to any securities or other property
deposited hereunder. The Escrow Agent shall have no responsibility for the contents of any writing of any third party contemplated herein as a means to resolve disputes and may rely without any liability upon the contents thereof. 

(j) In the event of any dispute between or conflicting claims by or among the Company and Madison Williams with respect to any Escrow
Property, the Escrow Agent shall be entitled, in its sole discretion, to refuse to comply with any and all claims, demands or instructions with respect to such Escrow Property so long as such dispute or conflict shall continue, and the Escrow Agent
shall not be or become liable in any way to the Company or Madison Williams for failure or refusal to comply with such conflicting claims, demands or instructions. The Escrow Agent shall be entitled to refuse to act until, in its sole discretion,
either (i) such conflicting or adverse claims or demands shall have been determined by a final order, judgment or decree of a court of competent jurisdiction, which order, judgment or decree is not subject to appeal, or settled by agreement
between the conflicting parties as evidenced in a writing signed by an Authorized Person of each of the parties and satisfactory to the Escrow Agent, or (ii) the Escrow Agent shall have received security or an indemnity satisfactory to it
sufficient to hold it harmless from and against any and all losses that it may incur by reason of so acting. The Escrow Agent may, in addition, elect, in its sole discretion, to commence an interpleader action or seek other judicial relief or orders
as it may deem, in its sole discretion, necessary. The costs and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such proceeding shall be paid by, and shall be deemed an obligation of, the Company.

 9. Termination. 

(a) This Agreement shall terminate upon the earlier of (i) payment pursuant to Section 6 of all amounts held in the
Escrow Account, or (ii) earlier notification in accordance with this Section 9. 
 (b) The Escrow Agent may at
any time resign by giving 30 days written notice of resignation to the Company and Madison Williams. Upon receiving such notice of resignation, the Company and Madison Williams shall promptly appoint a successor and, upon the acceptance by the
successor of such appointment, release the resigning Escrow Agent from its obligations hereunder (other than obligations and liabilities as determined by a court of competent jurisdiction to have been caused by the prior willful misconduct or gross
negligence of the Escrow Agent) by written instrument, a copy of which instrument shall be delivered to the resigning Escrow Agent and the successor. If no successor shall have been so appointed and have accepted appointment within such 30 day
period, the resigning Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor. The costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Escrow Agent in connection

with such proceeding shall be paid by, and be deemed an obligation of, the Company. The Escrow Agent’s sole responsibility after such 30 day notice period expires shall be to hold the Escrow
Property and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions or a final order or judgment of a court of competent jurisdiction, at which time of delivery the Escrow Agent’s obligations
hereunder shall cease and terminate. 
 (c) The Company and Madison Williams, by issuing a joint written instruction to the
Escrow Agent, shall have the right to terminate the appointment of the Escrow Agent. Such joint written instruction shall specify the date upon which such termination shall take effect. Thereafter, the Escrow Agent shall have no further obligation
hereunder (other than obligations and liabilities as determined by a court of competent jurisdiction to have been caused by the prior willful misconduct or gross negligence of the Escrow Agent) except to hold the Escrow Property as depository. The
Company and Madison Williams agree that in the event of such termination, they will cooperate with each other to jointly appoint a banking corporation, trust company or attorney as successor Escrow Agent and the Company shall pay the Escrow
Agent’s fees, costs and expenses or other obligations owed to Escrow Agent hereunder. The Escrow Agent shall refrain from taking any action until receiving written instructions jointly signed by the Company and Madison Williams designating the
successor Escrow Agent. 
 10. Fees. As consideration for its agreement to act as Escrow Agent as herein described, the
Company agrees upon demand to pay the Escrow Agent fees determined in accordance with the terms set forth on Exhibit G hereto (made a part of this Agreement as if herein set forth). In addition, the Company agrees to reimburse the Escrow
Agent for all reasonable expenses, disbursements and advances incurred or made by the Escrow Agent in performance of its duties hereunder (including reasonable fees, expenses and disbursements of its counsel). 

11. Indemnification of Escrow Agent. The Company and Madison Williams shall jointly and severally be liable for and shall jointly
and severally reimburse and indemnify, defend and hold harmless the Escrow Agent and its officers, directors, employees, representatives and agents, from and against and any and all claims, expenses, obligations, liabilities, losses, damages,
actions, suits, judgments, reasonable costs and expenses (including reasonable attorneys’ fees and expenses) suffered or incurred by the Escrow Agent relating to, or arising from the acceptance and performance of its obligations hereunder, or
from any claims against the Escrow Agent by reason of its participation in the transactions contemplated hereby, except to the extent caused by the Escrow Agent’s own gross negligence or willful misconduct. The obligations of the Company and
Madison Williams provided for in this Section 11 shall survive the termination of this Agreement and the resignation or removal of the Escrow Agent. 

12. Governing Law; Consent to Jurisdiction. This Agreement shall be interpreted, construed, enforced and administered in
accordance with the internal substantive laws (and not the choice of law rules) of the State of New York. The parties hereby submit to the personal jurisdiction of, and agree that all proceedings relating hereto shall be brought in, courts located
within the City and State of New York. The parties hereby waive the right to trial by jury and to assert counterclaims in any such proceedings. To the extent that in any jurisdiction either party may be entitled to claim, for itself or its assets,
immunity from suit, execution, attachment (whether before or after judgment) or other legal process, each hereby irrevocably agrees not to claim, and hereby waives, such immunity. The parties waive personal service of process and consent to service
of process by certified or registered mail, return receipt requested, directed to it at the address last specified for notices hereunder, and such service shall be deemed completed ten (10) calendar days after the same is so mailed.

14. Inurement; Assignment. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their
respective successors and assigns, heirs, administrators and representatives, and shall not be enforceable by or inure to the benefit of any other third party. No party may assign any of its rights or obligations under this Agreement without the
