Underwriting Agreement Standard Provisions

From time to time Talisman Energy Inc., a corporation organized under the laws of Canada (the “Company”), proposes to enter into one or more underwriting agreements in the form of Annex I hereto, with such additions and deletions as the parties thereto may determine, and, subject to the terms and conditions stated herein and therein, to issue and sell to the firms named in Schedule I to the applicable underwriting agreement (such firms constituting the “Underwriters” with respect to such underwriting agreement and the securities specified therein) certain of its debt securities (the “Securities”) specified in Schedule II to such underwriting agreement (with respect to such underwriting agreement, the “Designated Securities”). Each particular underwriting agreement shall be deemed to incorporate the provisions hereof (these “Standard Provisions”) into such underwriting agreement, and each such underwriting agreement, together with these Standard Provisions so incorporated therein, is collectively referred to as the “Underwriting Agreement”. The terms “this Agreement”, “hereof”, “herein” and similar terms mean the Underwriting Agreement including all Schedules thereto and these Standard Provisions.

The terms and rights of any particular issuance of Designated Securities shall be as specified in the Underwriting Agreement relating thereto and in or pursuant to the indenture (the “Indenture”) identified in such Underwriting Agreement.

Particular sales of Securities may be made from time to time to the Underwriters of such Securities, for whom the firms designated as representatives of the Underwriters of such Securities in the Underwriting Agreement relating thereto will act as representatives (the “Representatives”). The term “Representatives” also refers to a single firm acting as sole representative of the Underwriters and to an Underwriter or Underwriters who act without any firm being designated as its or their representatives. The obligation of the Company to issue and sell any of the Securities and the obligation of any of the Underwriters to purchase any of the Securities shall be evidenced by the Underwriting Agreement with respect to the Designated Securities specified therein. Each Underwriting Agreement shall specify the aggregate principal amount of such Designated Securities, the initial public offering price of such Designated Securities, the purchase price to the Underwriters of such Designated Securities, the names of the Underwriters of such Designated Securities, the names of the Representatives of such Underwriters and the principal amount of such Designated Securities to be purchased by each Underwriter and shall set forth the date, time and manner of delivery of such Designated Securities and payment therefor. The Underwriting Agreement shall also specify (to the extent not set forth in the Indenture and the registration statement and prospectus with respect thereto) the terms of such Designated Securities. An Underwriting Agreement shall be in the form of an executed writing (which may be in counterparts), and may be evidenced by an exchange of facsimile communications or any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under each Underwriting Agreement shall be several and not joint.

(xxi) The execution, delivery and performance of this Agreement, the Indenture and the Designated Securities and the consummation of the transactions contemplated in this Agreement and in the Canadian Prospectus and the U.S. Prospectus do not and will not, whether with or without the giving of notice or lapse of time or both: (1) to the knowledge of such counsel, conflict with or constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to any of the agreements to be listed in a schedule to the opinion to which the Company is a party; (2) result in any violation of the provisions of the articles or by-laws of the Company; (3) result in any violation of the provisions of any applicable Canadian federal or Alberta law, statute, rule or regulation; or (4) to the knowledge of such counsel, violate the terms of any judgment, order, writ or decree of any Canadian federal or Alberta government, government instrumentality or court having jurisdiction over the Company or any of its properties, assets, or operations;

(xxii) A court of competent jurisdiction in the Province of Alberta (an “Alberta Court”) would recognize the choice of the law of the State of New York (“New York Law”) as the proper law governing this Agreement, the Designated Securities and the Indenture, provided that such choice of law is bona fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction) and legal, and provided that such New York Law is not contrary to public policy, as that term is applied by an Alberta Court;

(xxiii) If this Agreement, the Designated Securities or the Indenture are sought to be enforced in the Province of Alberta in accordance with the laws applicable thereto as chosen by the parties, namely, New York Law, and an Alberta Court recognizes the choice of New York Law, an Alberta Court would, if specially pleaded and upon appropriate evidence as to such law being adduced, apply the substantive law of New York in the enforcement of such documents as the proper law governing such agreements in accordance with conflicts of law principles applied by Alberta Courts, provided that none of the provisions of this Agreement, the Designated Securities or the Indenture, or of applicable New York Law, is contrary to public policy as that term is applied by an Alberta Court, or otherwise seek to enforce foreign revenue, expropriatory or penal laws; provided, however, that, in matters of procedure, the laws of the Province of Alberta will be applied, including the Limitations Act (Alberta), and an Alberta Court will retain discretion to decline to hear such action if it is contrary to public policy, as that term is applied by an Alberta Court, or if it is not the proper forum to hear such an action, or if concurrent proceedings are being brought elsewhere;

(xxv) The laws of the Province of Alberta and the federal laws of Canada applicable therein permit an action to be brought before an Alberta Court on a final and conclusive in personam judgment for a sum certain of a New York Court respecting the enforcement of the Designated Securities, the Indenture or this Agreement that is not impeachable as void or voidable or otherwise ineffective under the internal laws of New York Law if: (1) the New York Court tendering such judgment had jurisdiction over the Company, as recognized by an Alberta Court (the appointment by the Company of CT Corporation System as its agent to receive service of process in the United States under the Registration Statement, the Indenture and this Agreement and the provisions in the Indenture and this Agreement whereby the Company has submitted to the non-exclusive jurisdiction of a New York Court and waiver of immunities is sufficient

for that purpose); (2) such judgment was not obtained by fraud or in a manner contrary to natural justice or other rule of law, whether equitable, legal or statutory and in the case of a judgment obtained by default there has been no manifest error in the granting of such judgment; (3) the enforcement of such judgment would not be inconsistent with public policy as such term is understood under the laws of the Province of Alberta or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada); (4) the enforcement of such judgment does not constitute, directly or indirectly, the enforcement of foreign revenue, expropriatory or penal laws; (5) no new admissible evidence relevant to the action is discovered prior to the rendering of judgment by an Alberta Court; (6) performance of this Agreement, the Designated Securities or the Indenture is not illegal under the laws of the place of performance; and (7) the action to enforce such judgment is commenced within the applicable limitation periods;

(xxvi) The Company is subject to the relevant commercial law and common laws of the Province of Alberta and is generally subject to suit in the Province of Alberta and the Company does not have any right of immunity from any judicial proceedings in the Province of Alberta;

(xxvii) No goods and services tax imposed under the federal laws of Canada or the laws of the Province of Alberta will be collectible by an Underwriter in respect of the issuance and sale to an Underwriter of the Designated Securities as contemplated by this Agreement, including the payment or crediting of any discount, commission or fee as contemplated by this Agreement, provided that any such discount, commission or fee is payable in respect of services performed by such Underwriter wholly outside of Canada; and

(xxviii) No stamp duty, registration or documentary taxes, duties or similar charges are payable by the Underwriters under the laws of the Province of Alberta or the federal laws of Canada applicable therein in connection with the creation, issuance and delivery to the Underwriters of the Designated Securities, the sale and delivery outside Canada by the Underwriters of the Designated Securities to the initial purchasers thereof, or the authorization, execution and delivery of the Indenture and this Agreement.

In rendering such opinion, such counsel may state that they express no opinion as to matters governed by laws other than the federal laws of Canada and the laws of the Province of Alberta. As to matters of law, other than the laws of the Province of Alberta and the federal laws of Canada, such counsel may rely upon the opinions of counsel reasonably satisfactory to the Representatives in which case the opinion shall state that they believe that both they and the Representatives are justified in so relying.

(vi) Assuming the due authorization, execution, issuance and delivery of the Designated Securities by the Company under Canadian federal and Alberta law, the Designated Securities (to the extent execution, issuance and delivery are governed by the laws of New York) have been duly executed, certified and delivered by the Company, and when issued by the Company against payment as provided by the Underwriting Agreement with respect to such Designated Securities, constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization, and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles entitled to the benefits provided by the Indenture.

In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the federal laws of the United States, the laws of the State of Washington or the laws of the State of New York. As to matters of Alberta and Canadian federal law, such counsel may rely upon the opinion of counsel of Macleod Dixon LLP, Canadian counsel for the Company, described in subsection (c) of this Section.

In addition to rendering the opinions set forth above, such counsel shall also include a statement to the effect that such counsel has participated in the preparation of the Registration Statement and the U.S. Prospectus and in conferences with officers and other representatives of the Company, Canadian counsel for the Company, representatives of the independent accountants for the Company, counsel for the Underwriters and representatives of the Underwriters at which the contents of the Registration Statement and U.S. Prospectus and related matters were discussed and although such counsel has not independently verified, and (except as to those matters and to the extent set forth in the opinions referred to in subsections (ii) and (iii) of this Section 6(d)) is not passing upon and does not assume any responsibility for, the factual accuracy, completeness or fairness of the statements contained in the Registration Statement and U.S. Prospectus, on the basis of such participation, no facts have come to such counsel’s attention which have caused such counsel to believe that (i) at the time it became effective and as of the time the Underwriting Agreement was entered into, the Registration Statement (other than the financial statements and other financial data and the information derived from the report of the internal qualified reserves evaluator in reliance on the authority of such evaluator as an “expert” within the meaning of the Securities Act, included or incorporated by reference in the Registration Statement, as to which such counsel need express no belief), contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) as of the date of the U.S. Prospectus Supplement and as of the Time of Delivery for the Designated Securities, the U.S. Prospectus (other than the financial statements and other financial data and the information derived from the report of the internal qualified reserves evaluator in reliance on the authority of such evaluator as an “expert” within the meaning of the Securities Act, included or incorporated by reference in the U.S. Prospectus, as to which such counsel need express no belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(i) The Company shall have complied with the provisions of Section 4(c) hereof with respect to the furnishing of prospectuses; and

(j) Prior to the Time of Delivery, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

7. Termination. The Underwriting Agreement shall be subject to termination in the sole discretion of the Representatives by notice to the Company given prior to the Time of Delivery if, at or prior to the Time of Delivery, (a) trading in securities generally on the New York Stock Exchange or the Toronto Stock Exchange shall have been suspended or materially limited; (b) trading of any securities of the Company shall have been suspended on the New York Stock Exchange or the Toronto Stock Exchange; (c) a general moratorium on commercial banking activities shall have been declared by appropriate authorities in the United States, Canada or New York State; (d) there shall have occurred (i) an outbreak or escalation of hostilities between the United States and any foreign power, (ii) an outbreak or escalation of any other insurrection or armed conflict involving the United States, or (iii) any other calamity or crisis or materially adverse change in general economic, political or financial conditions having an effect on the U.S. financial markets that, in the sole judgment of the Representatives, makes it impractical or inadvisable to proceed with the offering or the delivery of the Designated Securities as contemplated by the U.S. Prospectus.

8. Indemnity.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject, under Alberta Securities Law, the Securities Act, the Exchange Act 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 of a material fact contained in the Canadian Prospectus, the U.S. Prospectus or the Registration Statement, or any amendment or supplement thereto, 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 agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending such loss, claim, damage, liability or action 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 any such untrue statement or alleged untrue statement or omission or alleged omission made in the Canadian Prospectus, the U.S. Prospectus, the Registration Statement, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company and each of its directors, officers, employees and agents against all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject, under Alberta Securities Law, the Securities Act, the Exchange Act 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 of a material fact contained in the Canadian Prospectus, the U.S. Prospectus, the Registration Statement or any amendment or supplement thereto, 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 any 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 or on behalf of any Underwriter through the Representatives specifically for inclusion therein; and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending such loss, claim, damage, liability or action as such expenses are incurred. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement of the action; but the failure so to notify the indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and, in any event, shall not relieve it from any liability which it may have otherwise than under subsection (a) or (b) above. In case any such action shall be brought against any indemnified party, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, acting reasonably, and, after notice from the indemnifying party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation unless such indemnified party shall have reasonably concluded that there may be defenses available to it which are different from, additional to or in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), in which event such legal and other expenses shall be borne by the indemnifying party and paid as incurred (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one action or series of related actions in the same jurisdiction representing the indemnified parties who are parties to such action). No indemnifying party shall, without the written consent

of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim 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 any indemnified party.

(d) If the indemnification provided for in this Section 8 is for any reason unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then the Company and the Underwriters severally agree to contribute to the aggregate amount of such losses, claims, damages or liabilities (or actions in respect thereof) incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Designated Securities, or (ii) if the allocation provided by clause (i) 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 of the indemnified party on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Designated Securities pursuant to this Agreement shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault of the parties shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) 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 above in this Section 8(d). The aggregate amount of losses, claims, damages or liabilities (or actions in respect thereof) incurred by an indemnified party and referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing for or defending against any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Designated 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 any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8(d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company and each officer of the Company who signed the Canadian Prospectus, the U.S. Prospectus, the Registration Statement or any amendment or supplement thereto shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 8(d). The obligations of the Underwriters in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations with respect to the Designated Securities and not joint.

9. Default by an Underwriter.

(a) If any Underwriter shall default in its obligation to purchase the Designated Securities which it has agreed to purchase under the Underwriting Agreement, the Representatives may in their discretion arrange for themselves, another Underwriter or, with the consent of the Company (which consent will not be unreasonably withheld or delayed), another party or other parties to purchase such Designated Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Designated Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Designated Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Designated Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Designated Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for such Designated Securities for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the U.S. Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the U.S. Prospectus or the Canadian Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to the Underwriting Agreement.

(b) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount

of such Designated Securities which remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Designated Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Designated Securities which such Underwriter agreed to purchase under the Underwriting Agreement relating to such Designated Securities and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Designated Securities which such Underwriter agreed to purchase under the Underwriting Agreement) of the Designated Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Designated Securities which remains unpurchased exceeds one-tenth of the aggregate principal amount of the Designated Securities as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Designated Securities of a defaulting Underwriter or Underwriters, then the Underwriting Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 5 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter or the Company, or any officer or director of the Company, and shall survive delivery of and payment for the Designated Securities.

11. Consequences of Non-Completion. If the Underwriting Agreement shall be terminated pursuant to Section 7 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Designated Securities except as provided in Sections 5 and 8 hereof; but, if for any other reason, the Designated Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all reasonable out-of-pocket expenses, including reasonable fees and disbursements of counsel, incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Designated Securities, but the Company shall then be under no further liability to any Underwriter with respect to the Designated Securities except as provided in Sections 5 and 8 hereof.

12. Authority of Representatives; Notices. In all dealings hereunder, the Representatives of the Underwriters shall act on behalf of each of such Underwriters, and the parties hereto

shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Underwriting Agreement.

All statements, requests, notices, and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the address of the Representatives as set forth in the Underwriting Agreement; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Corporate Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. Inurement. The Underwriting Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 7 hereof, the officers and directors of the Company and each person who controls any Underwriter and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of the Underwriting Agreement. No purchaser of any of the Designated Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

14. Submission to Jurisdiction; Agent for Service. The Company irrevocably (i) agrees that any legal suit, action or proceeding against the Company brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any Court in the city of New York, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding or to the convenience of the forum and (iii) submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company has appointed CT Corporation System as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any New York Court by any Underwriter or by any person who controls any Underwriter, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. The Company represents and warrants that the Authorized Agent has agreed to act as such agent for service of process and agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to the Company shall be deemed, in every respect, effective service of process upon the Company.

15. Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than United States dollars, the Company will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and cost of exchange payable in connection with the purchase of or conversion into United States dollars.

16. Time of Essence. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

17. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

18. Counterparts. This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

19. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof.
