Ladies and Gentlemen:

Toreador Resources Corporation, a Delaware corporation (the “Issuer”), proposes to sell to the several underwriters (the “Underwriters”) named in Schedule I hereto an aggregate of 3,000,000 shares (the “Firm Securities”) of the Issuer’s common stock, par value $0.15625 per share (“Common Stock”). The respective amounts of the Firm Securities to be so purchased by the several Underwriters are set forth opposite their names in Schedule I hereto. The Issuer also proposes to sell at the Underwriters’ option an aggregate of up to 450,000 additional shares of the Issuer’s Common Stock (the “Option Securities”) as set forth below.

You have advised the Issuer (a) that you are authorized to enter into this Agreement, and (b) that the several Underwriters are willing, acting severally and not jointly, to purchase the numbers of Firm Securities set forth opposite their respective names in Schedule I, plus their pro rata portion of the Option Securities if the Underwriters elect to exercise the over-allotment option in whole or in part. The Firm Securities and the Option Securities (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”

The Issuer has prepared and filed a registration statement on Form S-3 (File No. 333-163067), as amended, with respect to the Shares pursuant to the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations (the “Rules and Regulations”) of the United States Securities and Exchange Commission (the “Commission”) thereunder.

Any reference to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents incorporated by reference therein pursuant to Form S-3 under the Securities Act as of the date of such Preliminary Prospectus or the Prospectus, as the case may be.

1. REPRESENTATIONS AND WARRANTIES OF THE ISSUER.

The Issuer represents and warrants to each of the Underwriters as follows:

(a) The Registration Statement has been filed with the Commission under the Securities Act and has been declared effective by the Commission under the Securities Act. No stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Issuer, threatened by, the Commission. The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus. Copies of the Registration Statement have been delivered or made available to you. The Registration Statement conformed, and any post-effective amendment to the

Registration Statement will conform in all material respects on the Effective Date and on the Closing Date (as defined below) and the Option Closing Date (as defined below), if any, to the requirements of the Securities Act and the Rules and Regulations. The most recent Preliminary Prospectus conformed, and the Prospectus will conform, in all material respects when filed with the Commission pursuant to Rule 424(b) and on the Closing Date and the Option Closing Date, if any, to the requirements of the Securities Act and the Rules and Regulations. As of the Effective Date and the date hereof, the Registration Statement did not and does not, and any further amendments to the Registration Statement will not, when they become effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; as of its date, on the Closing Date and the Option Closing Date, if any, the Prospectus will not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; the Disclosure Package, as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Issuer Free Writing Prospectus listed on Schedule II(b), taken together with the Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties set forth in this sentence do not apply to statements or omissions in the Registration Statement, the most recent Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Issuer by or on behalf of any Underwriter expressly for use therein, such information being listed in Section 12 below. Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use.

(b) This Agreement has been duly authorized, executed and delivered by the Issuer. The delivery and performance by the Issuer of its obligations under this Agreement has been duly and validly authorized.

The Issuer and each of the Subsidiaries are duly qualified to transact business and are in good standing in all jurisdictions in which the conduct of their business requires such qualification (if such concept exists in such jurisdiction); except where the failure to be so qualified or to be in good standing would not have a material adverse effect on the condition (financial or otherwise), properties, assets, operations, business or prospects of the Issuer and its Subsidiaries, taken as a whole (a “Material Adverse Effect”).

2. PURCHASE, SALE AND DELIVERY OF THE FIRM SECURITIES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Issuer agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $8.075 per share, the number of Firm Securities set forth opposite the name of each Underwriter in Schedule I hereof.

(b) Delivery of and payment for the Firm Securities shall be made at 10:00 A.M., New York City time, on the third full business day following the date of this Agreement or at such other time and date as shall be determined by agreement between the Underwriters and the Issuer. This date and time are herein referred to as the “Closing Date.” Delivery of the Firm

Securities shall be made to the Underwriters for the account of each Underwriter against payment by the several Underwriters of the aggregate purchase price of the Firm Securities to or upon the order of the Issuer by wire transfer in immediately available funds to the accounts specified by the Issuer. The Issuer shall deliver the Firm Securities through the facilities of Depositary Trust Company unless the Underwriters shall otherwise instruct. As used herein, “business day” means a day on which banks in New York are open for business and are not permitted by law or executive order to be closed.

(c) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Issuer hereby grants an option to the several Underwriters to purchase the Option Securities at the price per share as set forth in the paragraph (a) of this Section. The option granted hereby may be exercised in whole or in part by you by giving written notice to the Issuer (i) at any time before the Closing Date and (ii) only once thereafter within 30 calendar days after the date of this Agreement, setting forth the number of Option Securities as to which the several Underwriters are exercising the option and the time and date at which such Option Securities are to be delivered.

The option with respect to the Option Securities granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Securities by the Underwriters. The Underwriters may cancel such option at any time prior to the Option Closing Date by giving written notice of such cancellation to the Issuer. To the extent, if any, that the option is exercised, payment for the Option Securities shall be made on the Option Closing Date by wire transfer in immediately available funds, and delivery of the Option Securities shall be made through the facilities of the Depository Trust Company.

The Firm Securities are to be initially offered to the public at the public offering price set forth in the Prospectus. To the extent, if at all, that any Option Securities are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

4. Covenants.

Statement or supplement to the Prospectus, any Preliminary Prospectus or any Issuer Free Writing Prospectus of which the Underwriters shall not previously have been advised and furnished with a copy or to which the Underwriters shall have promptly reasonably objected in writing or which is not in compliance with the Rules and Regulations; and (iii) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Issuer with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters.

(b) The Issuer will not distribute any prospectus or other offering material (including, without limitation, any offer relating to the Shares that would constitute a “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) required to be filed by the Issuer with the Commission under Rule 433 of the Rules and Regulations) in connection with the offering and sale of the Shares, other than the materials referred to in Section 1(a) without the prior consent of the Underwriters. Each Underwriter represents and agrees that it has not made and, without the prior consent of the Issuer and the Underwriters, will not make, any offer relating to the Shares that would constitute a free writing prospectus. Any Issuer Free Writing Prospectus the use of which has been consented to by the Issuer and the Underwriters is listed on Schedule II(a) or Schedule II(b) hereto. The Issuer will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending. The Issuer will satisfy the conditions under Rule 433 of the Rules and Regulations to avoid a requirement to file with the Commission any electronic road show. The Issuer agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Prospectus or the Disclosure Package or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Issuer will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Issuer by an Underwriter expressly for use therein.

(c) The Issuer will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Issuer.

(d) The Issuer will advise the Underwriters promptly (i) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information; and (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Issuer will use its best efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(e) The Issuer will cooperate with the Underwriters in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Underwriters may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Issuer shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Issuer will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Underwriters may reasonably request for distribution of the Shares.

(f) The Issuer will deliver to, or upon the order of, the Underwriters, from time to time, as many copies of any Preliminary Prospectus as the Underwriters may reasonably request. The Issuer will deliver to, or upon the order of, the Underwriters during the period when delivery of a Prospectus is required under the Securities Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Underwriters may reasonably request.

(g) The Issuer will comply with the Securities Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Issuer or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Issuer promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or prepare and file with the Commission an appropriate filing under the Exchange Act, which shall be incorporated by reference in the Prospectus, so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(h) The Issuer will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 18 months after the Effective Date, an earning statement (which need not be audited) of the Issuer and its Subsidiaries complying with the requirements of Section 11(a) of the Securities Act and, at the option of the Issuer, Rule 158 of the Rules and Regulations.

(i) Prior to the Closing Date, the Issuer will furnish to the Underwriters, as soon as they have been prepared by or are available to the Issuer, a copy of any unaudited interim financial statements of the Issuer for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement and the Prospectus.

(j) The Issuer covenants and agrees that no offering, sale, short sale or other disposition of any shares of Common Stock of the Issuer or other securities convertible into or exchangeable or exercisable for shares of Common Stock or derivative of Common Stock (or

agreement for such) will be made for a period of 90 days after the date of this Agreement, directly or indirectly, by the Issuer otherwise than hereunder or with the prior written consent of the Underwriters; provided, that this provision shall not apply to the Shares to be sold hereunder, any shares of Common Stock issued by the Issuer upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof, or any shares of Common Stock issued or to be issued, or options to purchase Common Stock granted or to be granted in the ordinary course of business consistent with past practice, pursuant to existing employee or non-employee director benefit or incentive plans.

(k) The Issuer will use its best efforts to list, subject to notice of issuance, the Shares on The Nasdaq Global Market.

(l) At or prior to the date hereof, the Issuer shall have furnished to the Underwriters a letter substantially in the form of Exhibit A-1 or A-2 hereto from each officer, director and stockholder of the Issuer named in Schedule III hereto addressed to the Underwriters (“Lockup Agreements”).

(m) The Issuer shall apply the net proceeds of its sale of the Shares as described under the heading “Use of Proceeds” in the Prospectus and the Disclosure Package and shall file reports with the Commission with respect to the sale of the Shares and the application of the proceeds therefrom as may be required in accordance with Rule 463 under the Securities Act.

(n) The Issuer shall not invest, or otherwise use the proceeds received by the Issuer from its sale of the Shares in such a manner as would require the Issuer to register as an investment company under the 0000 Xxx.

(o) The Issuer will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Issuer, a registrar for the Common Stock.

5. COSTS AND EXPENSES.

The Issuer will pay all costs, expenses and fees incident to the performance of the obligations of the Issuer under this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Issuer; the fees and disbursements of counsel for the Issuer; the cost of printing and delivering to, or as requested by, the Underwriters copies of any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus and any supplements or amendments thereto; the filing fees of the Commission; the filing fees and expenses (including reasonable and documented legal fees and disbursements of counsel for the Underwriters) incident to securing any required review by the FINRA of the terms of the sale of the Shares; the Listing Fee of The Nasdaq Global Market; and the expenses (including the reasonable and documented fees and disbursements of counsel for the Underwriters up to a maximum amount of $5,000) incurred in connection with the qualification of the Shares under State securities or Blue Sky laws.

The Issuer shall not, however, be required to pay for any of the Underwriters expenses (other than those related to qualification under FINRA regulation and State securities or Blue Sky laws as described above), including without limitation, the fees and expenses of counsel to

the Underwriters (other than those as described above), the roadshow expenses of the Underwriters and the advertising expenses of the Underwriters incurred in connection with the sale of the Shares, except that, if the sale of the Shares shall not be consummated because the conditions in Section 6 hereof are not satisfied or this Agreement is terminated by the Underwriters pursuant to Section 10(a)(i) or Section 10(a)(v) hereof, then the Issuer shall reimburse the several Underwriters for reasonable and documented out-of-pocket expenses, including all reasonable and documented and fees and disbursements of its counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Issuer shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.

6. CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.

7. CONDITIONS OF THE OBLIGATIONS OF THE ISSUER.

The obligations of the Issuer to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the Closing Date or the Option Closing Date, if any, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened.

8. INDEMNIFICATION.

(a) The Issuer agrees:

(i) to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities arise out of (i) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing

Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or (C) any “road show” not constituting an Issuer Free Writing Prospectus or (ii) 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.

(ii) to reimburse each Underwriter and each such controlling person upon demand for any reasonable and documented legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto;

provided, however, that the Issuer 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, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or such amendment or supplement, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act in reliance upon and in conformity with written information furnished to the Issuer by or through the Underwriters specifically for use in the preparation thereof, such information being listed in Section 12 below.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Issuer, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Issuer within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Issuer or any such director, officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Issuer or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Issuer by or through the Underwriters specifically for use in the preparation thereof, such information being listed in Section 12 below.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, 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 reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) and by the Issuer in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(d) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings

in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer 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, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Issuer, on the one hand, and the Underwriters, on the other, in connection with the offering of the Shares shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Issuer, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Issuer, on the one hand, and the Underwriters, on the other, 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 Issuer, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Issuer and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection 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 Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Subsection, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) 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 Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

10. TERMINATION.

(a) This Agreement may be terminated by you by written notice to the Issuer at any time prior to the Closing Date if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, there has occurred, in the sole discretion of the Underwriters, a Material Adverse Effect, (ii) any outbreak, attack, or escalation of hostilities or declaration of war, national emergency, act of terrorism or other national or international calamity or crisis or material adverse change in general economic, financial or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or material adverse change on the financial markets of the United States would, in the sole discretion of the Underwriters, make it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, (iii) suspension of trading in securities generally on the New York Stock Exchange or The Nasdaq Global Market or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on either such Exchange, (iv) declaration of a banking moratorium by United States or New York State authorities or (v) the suspension of trading of the Issuer’s Common Stock by The Nasdaq Global Market, the Commission, or any other governmental authority.

(b) If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Sections 5 and 8 hereof, and provided further that Sections 1, 8 and 14 shall survive such termination and remain in full force and effect.

11. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Issuer and Underwriters and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.

12. INFORMATION PROVIDED BY UNDERWRITERS.

The Issuer and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Issuer for inclusion in any Preliminary Prospectus, Prospectus, Issuer Free Writing Prospectus or the Registration Statement consists of the information in the third, ninth, tenth, eleventh, twelfth and fifteenth paragraphs under the caption “Underwriting” in the Prospectus.

13. RESEARCH INDEPENDENCE.

In addition, the Issuer acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Issuer and/or the offering that differ from the views of its investment bankers. The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by such Underwriters’ investment banking divisions. The Issuer acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short position in debt or equity securities of the companies which may be the subject to the transactions contemplated by this Agreement.

14. NO FIDUCIARY DUTY.

Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the underwriters, the Issuer acknowledges and agrees that:

(a) nothing herein shall create a fiduciary or agency relationship between the Issuer and the Underwriters;

(b) the Underwriters are not acting as advisors, expert or otherwise, to the Issuer in connection with this offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares;

(c) the relationship between the Issuer and the Underwriters is entirely and solely commercial, based on arms-length negotiations;

(d) any duties and obligations that the Underwriters may have to the Issuer shall be limited to those duties and obligations specifically stated herein; and

(e) notwithstanding anything in this Underwriting Agreement to the contrary, the Issuer acknowledges that the Underwriters may have financial interests in the success of the Offering that are not limited to the difference between the price to the public and the purchase price paid to the Issuer by the Underwriters for the shares and the Underwriters have no obligation to disclose, or account to the Issuer for, any of such additional financial interests.

The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty in connection with this offering.

15. MISCELLANEOUS.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any investigation made by or on behalf of any Underwriter or controlling person thereof, or by or on behalf of the Issuer or its directors or officers and (b) delivery of and payment for the Shares under this Agreement.

This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

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.

This Agreement may only be amended or modified in writing, signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.
