References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, each Selling Shareholder agrees, severally and not jointly, to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from each Selling Shareholder, at a purchase price of $5.38 per share, that number of Firm Securities obtained by multiplying the number of Firm Securities set forth opposite the name of such Selling Shareholder in Schedule A hereto, as the case may be, by a fraction, the numerator of which is the number of Firm Securities set forth opposite the name of such Underwriters in Schedule B hereto and the denominator of which is the total number of Firm Securities.

The Selling Shareholders will deliver the Firm Securities to or as instructed by the Underwriters for the accounts of the several Underwriters in a form reasonably acceptable to the Underwriters against payment of the purchase price in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Underwriters as specified by the Selling Shareholders to the Underwriters at least 24 hours prior to the First Closing Date (as defined below), at the office of Xxxxxxx Xxxxxxx & Xxxxxxxx LLP, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, at 9:00 A.M., New York time, on November 29, 2018, or at such other time not later than seven full business days thereafter as the Underwriters and the Company determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The Firm Securities so to be delivered or evidence of their issuance will be made available for checking at the office of Xxxxxxx Xxxxxxx & Xxxxxxxx LLP described above at least 24 hours prior to the First Closing Date.

In addition, upon not less than two business days written notice from the Underwriters given to the Company and the Selling Shareholders from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per Security to be paid for the Firm Securities, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Firm Securities but not payable on the Optional Securities. The Selling Shareholders agree to sell, severally and not jointly, to the Underwriters the respective number of Optional Securities obtained by multiplying the number of Optional Securities specified in such notice by a fraction the numerator of which is the number of shares set forth opposite the names of such Selling Shareholders in Schedule A hereto under the caption “Number of Optional Securities to be Sold” and the denominator of which is the total number of Optional Securities, and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of the several Underwriters in the same proportion as the number of shares of Firm Securities set forth opposite such Underwriters’ name bears to the total number of shares of Firm Securities (subject to adjustment by the Underwriters to eliminate fractions). No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Underwriters to the Company and the Selling Shareholders.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by the Underwriters but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. The Selling Shareholders will deliver the Optional Securities being purchased on each Optional Closing Date to or as instructed by the Underwriters for the accounts of the several Underwriters in a form reasonably acceptable to the Underwriters, against payment of the purchase price therefor in Federal (same day) funds by wire transfer to an account at a bank acceptable to the Underwriters as specified by the Selling Shareholders at the office of Xxxxxxx Xxxxxxx & Xxxxxxxx LLP described above. The Optional Securities being purchased on each Optional Closing Date or evidence of their issuance will be made available for checking at the office of Xxxxxxx Xxxxxxx & Xxxxxxxx LLP described above at a reasonable time in advance of such Optional Closing Date.

Without limiting the applicability of Section 3 hereof or any other provision of this Agreement, with respect to any Underwriter who is affiliated with any person or entity engaged to act as an investment adviser on behalf of a client who has a direct or indirect interest in the Offered Securities being sold by a Selling Shareholder, the Offered Securities being sold to such Underwriter shall not include any Securities attributable to such client (with any such shares instead being allocated and sold to the other Underwriters) and, accordingly, the fees or other amounts received by such Underwriter in connection with the transactions contemplated hereby shall not include any fees or other amounts attributable to such client.

(c) Notice of Material Changes. Such Selling Shareholder will advise the Underwriters promptly, and if requested by the Underwriters, will confirm such advice in writing, so long as delivery of a prospectus relating to the Securities by an underwriter or dealer may be required under the Act, of any material change in Selling Shareholder Information.

(d) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final 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 Final Prospectus to comply with the Act, the Company will promptly notify the Underwriters of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Underwriters, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Underwriters’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(e) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the Effective Time of the Registration Statement which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the 45th day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 90th day after the end of such fourth fiscal quarter.

(f) Furnishing of Prospectuses. The Company will furnish to the Underwriters signed copies of the Registration Statement (including all exhibits), each

related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Underwriters request. The Final Prospectus shall be so furnished on or prior to 3:00 P.M., New York time, on the business day following the execution and delivery of this Agreement unless otherwise agreed by the Underwriters. All other such documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(g) Blue Sky Qualifications. The Company will cooperate with the Underwriters for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Underwriters designate and to continue such qualifications in effect so long as required for the distribution; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(h) Reporting Requirements.

However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval (“XXXXX”) system, it is not required to furnish such reports or statements to the Underwriters.

(i) Payment of Expenses. The Company agrees with the several Underwriters that the Company will pay all expenses incidental to the performance of the obligations of the Company and the Selling Shareholders under this Agreement, including but not limited to any filing fees and other expenses (including fees and disbursements of counsel to the Underwriters) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Underwriters designate and the preparation and printing of “Blue Sky” memoranda relating thereto (including the related fees and expenses of counsel for the Underwriters), costs and expenses related to the review by FINRA (if any) of the Offered Securities (including filing fees and the fees and expenses of counsel for the Underwriters relating to such review), costs and expenses relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s officers and employees and any other expenses of the Company including

(j) Absence of Manipulation.

(k) Taxes. The Selling Shareholders will, severally and not jointly, indemnify and hold harmless the Underwriters against any documentary, stamp or similar issue tax arising under laws other than those of the United States, including any interest and penalties, on the sale or transfer of the Offered Securities to the Underwriters and on the execution and delivery of this Agreement. All payments to be made by the Company and each Selling Shareholder hereunder shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company or such Selling Shareholder is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company or such Selling Shareholder shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made.

(l) Restriction on Sale of Securities by Company.

6. Free Writing Prospectuses. The Company and the Selling Shareholders represent and agree that, unless they obtain the prior consent of the Underwriters, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

7. Conditions of the Obligations of the Underwriters.

such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with (i) written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below or (ii) any Selling Shareholder Information with respect to that Selling Shareholder.

(b) Indemnification of Underwriters by Selling Shareholders. The Selling Shareholders, severally and not jointly, will indemnify and hold harmless each Indemnified Party against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in reliance upon and in conformity with the Selling Shareholder Information with respect to that Selling Shareholder, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to the above as such expenses are incurred; provided, however, that the liability under this subsection of each Selling Shareholder shall be limited to an amount equal to the aggregate proceeds (less underwriters’ discounts and commissions, but before other expenses) to such Selling Shareholder from the Offered Securities sold by such Selling Shareholder.

(c) Indemnification of Company and the Selling Shareholders. Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and each Selling Shareholder and each person, if any, who controls a selling shareholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”) against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement at any time, any Statutory Prospectus at any time, the Final Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission of 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 reliance upon and in conformity with written information furnished to the Company by such Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: (i) the first sentence of the fourth paragraph and the second sentence of the sixth paragraph under the heading “Underwriting” and (ii) the information contained under the heading “Underwriting—Price Stabilization and Short Positions.”

(d) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) 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), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be

liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, from the offering of the Offered Securities 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 Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (less underwriting discounts and commissions but before deducting expenses) received by the Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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 or the Selling Shareholders or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), (1) no Selling Shareholder shall be required to contribute pursuant to this subsection (e), (i) unless such Selling Shareholder would have had indemnification obligations pursuant to subsection (b) above or (ii) any amount in excess of the amount by which such Selling Shareholder’s aggregate proceeds (less underwriter’s discounts and commissions, but before other expenses) received by it from the sale of the Offered Securities pursuant to this Agreement exceeds the amount of any damages which such Selling Shareholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and (2) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at

which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(e). No Selling Shareholder shall have any liability under Section 8(b) and this Section 8(e), in the aggregate, in excess of such Selling Shareholder’s aggregate proceeds (less underwriting discounts and commissions, but before deducting expenses) received by it from the sale of the Offered Securities pursuant to this Agreement.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Shareholders and the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, any Selling Shareholder, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling Shareholders and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

10. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telefaxed and confirmed to the Underwriters at Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attn: Syndicate Registration, Fax No.: (000) 000-0000; with a copy to Xxxxxxx Xxxxxxx & Xxxxxxxx LLP, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Xxxxx Xxxxxx, Esq., or, if sent to the Company, will be mailed or delivered and confirmed to it at Kosmos Energy Ltd., x/x Xxxxxx Energy, LLC, 0000 Xxxx Xxxx, Xxxxx 000, Xxxxxx, XX 00000, Attention: General Counsel, with a copy to Xxxxx Xxxx & Xxxxxxxx LLP, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Xxxxx X.

Xxxxx X. Xxxxxx, Xx., Esq.; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective personal representatives and successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

13. Absence of Fiduciary Relationship. Each of the Company and each Selling Shareholder acknowledges and agrees that:

(a) No Other Relationship. The Underwriters have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Underwriters have advised or are advising the Company or the Selling Shareholders on other matters;

(b) Arms’ Length Negotiations. The price of the Offered Securities set forth in this Agreement was established by the Selling Shareholders following discussions and arms-length negotiations with the Underwriters and the Selling Shareholders are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Company and the Selling Shareholders have been advised that the Underwriters and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and the Selling Shareholders and that the Underwriters have no obligation to disclose such interests and transactions to the Company or the Selling Shareholders by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Company and the Selling Shareholders waive, to the fullest extent permitted by law, any claims they may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including shareholders, employees or creditors of the Company.

14. Patriot Act Notice. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Shareholders, which information may include the name and address of

their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

15. Applicable Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company and the Selling Shareholders hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company and the Selling Shareholders irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in the City of New York and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

The obligations of the Company and the Selling Shareholders pursuant to this Agreement in respect of any sum due to any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company and the Selling Shareholders, as applicable, agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company and the Selling Shareholders, as applicable, an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.

If the foregoing is in accordance with the Underwriters’ understanding of our agreement, kindly sign and return to the Company and the Selling Shareholders one of the counterparts hereof, whereupon it will become a binding agreement, among the Company, the Selling Shareholders and the several Underwriters in accordance with its terms.

Very truly yours,
