(i) The Company has prepared a registration statement on Form S-1 (File No. [333-______]) with respect to the Shares, including a form of preliminary prospectus, in conformity with the requirements of the Act and the rules and regulations (the "Rules and Regulations") of the Securities and Exchange Commission (the "Commission") promulgated thereunder and has filed such registration statement with the Commission under the Act. The Company has prepared and filed such amendments thereto and such amended preliminary prospectuses as may have been required to the date hereof, and will file such additional amendments thereto and such amended preliminary prospectuses as may hereafter be required. The Company has delivered or caused to be delivered to the Representatives without charge two (2) signed copies of such registration statement and each amendment thereto together with two (2) copies of each exhibit filed therewith; one (1) conformed copy of such registration statement and each amendment thereto, but without exhibits, for each of the Underwriters if requested; and such number of the related Preliminary Prospectus (as hereinafter defined) and of the Prospectus as the Representatives heretofore have reasonably requested. As used in this Agreement, the term "Preliminary Prospectus" means each and every prospectus filed with the registration statement and amendments thereto (except the Prospectus). Such registration statement, as amended, has been declared effective by the Commission under the Act and is not proposed to be further amended. If such registration statement, as it may have been amended, omits information in accordance with Rule 430A under the Act, promptly after the execution of this Agreement the Company will file with the Commission a prospectus in the form most recently included in an amendment to such registration statement (or, if no such amendment shall have been filed, in such registration -4- statement) with such changes or insertions as are required by Rule 430A or permitted by Rule 424(b) under the Act and as have been provided to and approved by the Representatives. Such registration statement, as finally amended and revised at the time such registration statement is or was declared effective by the Commission, and the information contained in the form of final prospectus, filed with the Commission pursuant to Rule 424(b) and Rule 430A of the Rules and Regulations and deemed to be part of the registration statement), is referred to herein as the "Registration Statement." "Prospectus" means (a) the form of prospectus first filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations or (b) the last preliminary prospectus included in the Registration Statement filed prior to the time it becomes effective or filed pursuant to Rule 424(a) under the Act that is delivered by the Company to the Underwriters for delivery to purchasers of the Shares, together with the term sheet or abbreviated term sheet filed with the Commission pursuant to Rule 424(b)(7). (j) The Common Stock is registered pursuant to Section 12(g) of the Exchange Act. (k) Neither the Commission nor the securities authority of any state or other jurisdiction has issued any order preventing or suspending the use of any Preliminary Prospectus, and no proceeding for that purpose has been instituted or, to the best of the Company's knowledge after due inquiry, threatened by the Commission or any such securities authority. No stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceeding for that purpose has been instituted or, to the best of the Company's knowledge after due inquiry, threatened or contemplated by the Commission or any such securities authority. Each Preliminary Prospectus complies with the requirements of the Act and the Rules and Regulations and did not include any untrue statement of a material fact or omit 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. The Registration Statement and the Prospectus contained therein, and any amendments or supplements thereof, including without limitation the financial statements included in such Prospectus, contained or will contain all statements that are required to be stated therein in accordance with the Act and the Rules and Regulations and conformed or will conform in all respects to the requirements of the Act and the Rules and Regulations, and neither the Registration Statement nor the Prospectus, nor any amendment or supplement thereto, included or will include any untrue statement of a material fact or omitted or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. When the Prospectus or any amendment or supplement thereto is filed with the Commission pursuant to Rule 424(b) (or, if the Prospectus or such amendment or supplement is not required to be so filed, when the Registration Statement or amendment thereto containing such amendment or supplement to the Prospectus was or is declared effective), the Prospectus, as amended or supplemented at any such time, contained or will contain all statements that are required to be stated therein in accordance with the Act and the Rules and Regulations and conformed or will conform in all material respects to the requirements of the Act and the Rules and Regulations and did not or will not include any -5- untrue statements of a material fact or omitted or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made. No representation or warranty in this Section 2(k) is made as to information contained in or omitted from the Registration Statement, the Prospectus or any such amendment or supplement 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 in the Registration Statement or Prospectus or any amendment or supplement thereto.

Such counsel may rely as to factual matters on certificates of officers of the Company and of governmental officials, in each case satisfactory to the Representatives, in which case their opinion shall state that they are so doing and that they have no reason to believe that any such certificate is not complete and accurate, and copies of such certificates or opinions shall be attached to such counsel's opinion.] (iii) [AN OPINION OF KING & SPALDING, REGULATORY COUNSEL FOR THE COMPANY, DATED THE CLOSING DATE AND ADDRESSED TO YOU, AS REPRESENTATIVES OF THE SEVERAL UNDERWRITERS TO THE EFFECT THAT: ANY STATEMENTS SET FORTH IN THE REGISTRATION STATEMENT AND THE PROSPECTUS UNDER THE CAPTIONS "RISK FACTORS - GOVERNMENTAL REGULATION: AND "BUSINESS - GOVERNMENT REGULATION" (COLLECTIVELY, THE "FDA PORTION") CONSTITUTE AN ACCURATE SUMMARY IN ALL MATERIAL RESPECTS OF RESTRICTIONS APPLICABLE TO THE BUSINESS OF THE COMPANY ARISING UNDER THE FEDERAL FOOD, DRUG, AND COSMETIC ACT (THE "FFDCA") OR THE REGULATIONS THEREUNDER OR THE FDA REGULATION OF THE BUSINESS OR OPERATIONS OF THE COMPANY, OR OF ANY LEGAL -27- MATTERS, DOCUMENTS OR PROCEEDINGS REFERRED TO THEREIN AND RELATING TO THE FFDCA OR THE FDA'S REGULATION OF THE BUSINESS OR OPERATIONS OF THE COMPANY OR THE COMPANY'S COMPLIANCE THEREWITH.

(vi) Concurrently with the execution of this Agreement, each of the Accountants shall have delivered to the Representatives a letter, dated the date of this Agreement, addressed to the Representatives, as representatives of the Underwriters and the directors of the Company , in form and substance reasonably satisfactory to the Representatives, confirming that the Accountants are independent accountants with respect to the Company as required by the Act and the Rules and Regulations and with respect to certain financial and other statistical and numerical information contained in the Registration Statement.

There shall not have been any change or decrease set forth in any of the letters referred to in this Section 9(g)(vi) that makes it impracticable or inadvisable in the reasonable judgment of the Representatives to proceed with the public offering or purchase of the Shares contemplated hereby.

All such opinions, certificates, letters and documents shall be in compliance with the provisions of this Agreement only if they are reasonably satisfactory to the Representatives and to Ropes & Gray, counsel for the Underwriters. The Company shall furnish the -30- Representatives with such manually signed or conformed copies of such opinions, certificates, letters and documents as the Representatives reasonably may request.

(i) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall have been no litigation or other proceeding instituted against the Company, or any of its officers or directors in their capacities as such, for or by any foreign, federal, state, municipal or local court, commission, regulatory body, administrative agency or other governmental body, in which litigation or proceeding an unfavorable ruling, decision or finding would have a Material Adverse Effect. (j) Each of the representations and warranties of the Company contained in this Agreement shall be true and correct in all material respects at the First Closing Date and, with respect to the Option Shares, at the Second Closing Date, and all covenants and agreements contained in this Agreement to be performed on the part of the Company and all conditions contained herein to be fulfilled or complied with by the Company at or prior to the First Closing Date and, with respect to the Option Shares, at or prior to the Second Closing Date, shall have been duly performed, fulfilled or complied with.

If any condition to the Underwriters' obligations hereunder to be satisfied prior to or at the First Closing Date is not so satisfied, this Agreement, at the Representatives' election, shall, upon notification of the Company, terminate without liability on the part of any Underwriter, including without limitation the Representatives, or the Company, except for the expenses to be paid by the Company pursuant to Section 8 or reimbursed by the Company pursuant to Section 10 and except to the extent provided in Section 12. SECTION 10. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If the sale to the Underwriters of the Shares at the First Closing is not consummated because any condition to the Underwriters' obligations under this Agreement is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company agrees to reimburse the Representatives and the other Underwriters through you upon demand for all reasonable out-of-pocket expenses (including without limitation reasonable fees and disbursements of counsel) that shall have been incurred by the Representatives and the other Underwriters in connection with the -31- proposed purchase and the sale of Shares up to a maximum of $50,000. Any such failure of consummation shall be without liability of any party to any other except that the provisions of this Section 10 and Sections 8 and 12 shall at all times be effective and shall apply. SECTION 11. MAINTENANCE OF EFFECTIVENESS OF REGISTRATION STATEMENT. The Representatives and the Company shall use their respective best efforts to prevent the issuance of any stop order suspending the effectiveness of the Registration Statement and, if any such stop order is issued, to obtain the withdrawal of such order at the earliest possible moment. SECTION 12. INDEMNIFICATION. (a) The Company agrees to indemnify and hold harmless each Underwriter; the directors, officers, employees and agents of each Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act; from and against any losses, claims, damages, expenses, liabilities or actions in respect thereof (including without limitation any and all investigative, legal and other expenses reasonably incurred in connection with, and any amounts paid in settlement of, any action, suit or proceeding or any claim asserted) (collectively, "Claims"), whether joint or several, to which any such Underwriter, person or controlling person may become subject under the Act, the Exchange Act, any Blue Sky Law, or any other federal or state statutory law or regulation, at common law or otherwise (including without limitation payments made in settlement of any litigation, if such settlement is effected with the written consent of the Company, which consent shall not be unreasonably withheld), insofar as such Claims arise out of or are based upon 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 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 light of the circumstances in which they were made, and will reimburse each Underwriter, each such other person and each such controlling person for any reasonable legal fees or other expenses reasonably incurred by such Underwriter or any such other person party or any such controlling person in connection with investigating, defending against or appearing as a third witness in connection with any such Claim; provided, however, that the Company will not be liable in any such case to the extent that: (i) any such Claim arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission to state a material fact made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with the written information furnished by or on behalf of the Underwriters to the Company pursuant to Section 4; or -32- (ii) such untrue statement or alleged untrue statement or omission or alleged omission to state a material fact was contained or made in any Preliminary Prospectus and corrected in the Prospectus and (A) any such Claim suffered or incurred by any Underwriter (or any person who controls any Underwriter within the meaning of Section 15 of the Act of or Section 20 of the Exchange Act) resulted from a Claim by any person who purchased Shares that are the subject thereof from such Underwriter in the offering, and (B) such Underwriter failed to deliver a copy of the Prospectus (as then amended if the Company shall have amended the Prospectus) to such person at or prior to the confirmation of the sale of such Shares in any case where such delivery is required by the Act, unless such failure was due to failure by the Company to provide copies of the Prospectus (as so amended) to the Underwriters as required by this Agreement. The indemnification obligations of the Company pursuant to this Section 12(a) are in addition to any liabilities the Company may otherwise have. The Company will not, without the prior written consent of the Representatives, settle or compromise or consent to the entry of any judgment in any pending or threatened Claim (or related cause of action or portion thereof) in respect of which indemnification may be sought hereunder (whether or not any Underwriter is a party to such Claim), unless such settlement, compromise or consent includes an unconditional release of each Underwriter from all liability arising out of such Claim (or related cause of action or portion thereof). (b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, and each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any Claim to which the Company or any of its directors, officers or controlling persons or person controlling such persons may become subject under the Act, the Exchange Act, any Blue Sky Law or any other federal or state statutory law or regulation, at common law or otherwise (including without limitation payments made in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter and the Representatives, which consent shall not be unreasonably withheld), insofar as such Claims arise out of or are based upon any untrue 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 arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or any amendment or supplement by such Underwriter to the Company pursuant to Section 4. Each Underwriter will severally reimburse any legal fees or other expenses reasonably incurred by the Company, or any of its directors, officers or controlling persons or any of the controlling persons of such persons in connection with investigating or defending any such Claim, and from any and all Claims resulting from failure of an Underwriter to deliver a copy of the Prospectus, if the person asserting such Claim purchases Shares from such Underwriter and a copy of the Prospectus -33- (as then amended if the Company shall have amended the Prospectus) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended) would have cured the defect giving rise to such Claim. The indemnification obligations of each Underwriter pursuant to this Section 12(b) are in addition to any liabilities any such Underwriter may otherwise have. (c) Any party that proposes to assert its right to be indemnified under this Section 11 shall, promptly after receipt of notice of the commencement of any action against such party in respect of a Claim, if a Claim in respect thereof is to be made against an indemnifying party under this Section 11, notify each such indemnifying party in writing of the commencement thereof (a "Commencement Notice"), and such Commencement Notice shall include a copy of all papers served upon the notifying party, provided that the omission to so notify such indemnifying party or parties shall only relieve the indemnifying party or parties from any liability it or they may have to any indemnified party under this Section 11 to the extent that such omission to give such notice results in the loss of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party, and such indemnified party notifies an indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving a Commencement Notice, jointly with all other indemnifying parties similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded (based on advice of counsel) that there may be legal defenses available to the indemnified party and/or other indemnified parties that are different from or in addition to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties in accordance with clause (d) hereof. (d) Upon receipt of notice from the indemnifying party to such indemnified party of the indemnifying party's election to assume the defense of such action and upon approval by the indemnified party of counsel selected by the indemnifying party, the indemnifying party shall not be liable to such indemnified party under Section 12(a) or Section 12(b) for any legal fees or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than the reasonable costs of investigation subsequently incurred by the indemnified party in connection with such defense, unless: (i) the indemnified party shall have employed separate counsel in connection with the assumption of legal defenses in accordance with the proviso to the last sentence of Section 12(c) (it being understood, however, that the indemnifying party shall not be liable for the legal fees and expenses of more than one separate counsel, approved by the Representatives if one or more of the Underwriters or their controlling persons are the indemnified parties); or -34- (ii) the indemnifying party has authorized in writing the employment of counsel at the expense of the indemnifying party; or (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and any 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). It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges shall be reimbursed by the indemnifying party or parties promptly as they are incurred. No indemnifying party shall be liable for any settlement of any action or claim effected without such indemnifying party's written consent (which consent shall not be unreasonably withheld). (e) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 12 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Underwriters, the Company and the Underwriters shall contribute to the total losses, claims, liabilities, expenses and damages (including without limitation any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any Claim, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which each indemnified party may be subject as a result of such Claim: (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 Shares; or (ii) if the allocation provided by Section 12(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in Section 12(e)(i) above, but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such Claim, as well as any other relevant equitable considerations. The respective relative benefits received by the Company on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions and other compensation received by the -35- Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other hand 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 contributions pursuant to this Section 12(e) were to be 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 into account the equitable considerations referred to in this Section 12(e). The amount paid or payable by an indemnified party as a result of the Claims referred to above shall be deemed to include, subject to the limitations set forth in Sections 12(c) and 12(d), any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim. (f) Notwithstanding the other provisions of this Section 12, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions and other compensation received by it, and no person found 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 to contribute pursuant to this Section 12 are several in proportion to the respective number of Firm Shares set forth opposite their names in SCHEDULE A (or such number of Firm Shares increased as set forth in Section 12) and not joint. For purposes of this Section 12, any person who controls a party to this Agreement within the meaning of the Act shall have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement shall have the same rights to contribution as the Company, subject in each case to the provisions of this Section 12. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against any such party in respect of which a claim for contribution may be made under this Section 12, shall notify any such party or parties from whom contribution may be sought, but the omission so to notify shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 12. No party shall be liable for contribution with respect to any action or claim settled without its written consent (which consent shall not be unreasonably withheld). (g) The indemnity and contribution agreements contained in this Section 12 shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters, (ii) acceptance of any of the Shares and payment therefor or (iii) any termination of this Agreement. SECTION 13. SUBSTITUTION OF UNDERWRITERS. It shall be a condition to this Agreement and to the obligations of the Company to sell and deliver the Shares hereunder, and to the obligations of each Underwriter to purchase the Shares in the manner as described -36- herein, that, except as hereinafter provided in this Section 13, each of the Underwriters shall purchase and pay for all of the Shares agreed to be purchased by such Underwriter hereunder upon tender to the Representatives of all such Shares in accordance with the terms hereof. If any Underwriter or Underwriters defaults in its or their obligations to purchase Shares hereunder on either the First Closing Date or the Second Closing Date and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed ten percent (10%) of the total number of Shares the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements for the purchase of such Shares by other persons, including without limitation any of the Underwriters, but if no such arrangements are made by such Closing Date the nondefaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Shares such defaulting Underwriters agreed but failed or refused to purchase on such Closing Date, provided that in no event shall the maximum number of Shares which any Underwriter has become obligated to purchase pursuant to Section 5 be increased pursuant to this Section 13 by more than one-eleventh of such number of Shares without the prior written consent of such Underwriter. If any Underwriter or Underwriters so default and the aggregate number of Shares with respect to which such default or defaults occur is greater than the above percentage and arrangements satisfactory to the Representatives for the purchase of such Shares by other persons are not made within thirty-six (36) hours after such default, this Agreement shall terminate without liability on the part of any nondefaulting Underwriter or the Company, except for the expenses to be paid by the Company pursuant to Section 8 and except to the extent provided in Section 12. If the Shares to which such a default relates are to be purchased by the nondefaulting Underwriters or by another party or parties, the Representatives or the Company shall have the right to postpone the First or Second Closing Date, as the case may be, for not more than seven (7) business days so that the required changes in the Registration Statement, Prospectus and any other documents, as well as any other arrangements, may be effected. The term "Underwriter" shall include any person substituting for a defaulting Underwriter hereunder. Nothing contained in this Agreement shall relieve a defaulting Underwriter from liability for its default. SECTION 14. EFFECTIVE DATE OF THIS AGREEMENT. This Agreement shall become effective immediately upon the execution hereof on the date hereof. SECTION 15. TERMINATION. Without limiting the right to terminate this Agreement pursuant to any other provision hereof, this Agreement may be terminated by the Representatives prior to the First Closing Date and the Option, if exercised, may be canceled by the Representatives at any time prior to the Second Closing Date, prior to delivery of and payment for the applicable Shares, if in the Representatives' sole judgment, payment for and delivery of the Shares is rendered impracticable or inadvisable because: -37- (a) additional government restrictions, not in force and effect on the date hereof, shall have been imposed upon trading in securities generally or minimum or maximum prices shall have been generally established over-the-counter on the Nasdaq Stock Market or on the New York Stock Exchange, or trading in securities generally shall have been suspended or limited on the Nasdaq Stock Market or the New York Stock Exchange; or (b) a general banking moratorium shall have been established by federal, New York or Connecticut authorities; (c) any event shall have occurred or shall exist that makes untrue or incorrect in any material respect any statement or information contained in the Registration Statement or that is not reflected in the Registration Statement but should be reflected therein to make the statements or information contained therein not misleading in an material respect; or (d) any outbreak or escalation of major hostilities or other national or international calamity or crisis or any substantial change in political, financial or economic conditions or any other event or events shall have occurred or shall have accelerated to such extent, in the Representatives' sole judgment, as to have a material adverse effect on the general financial and/or securities markets of the United States or make it impracticable or inadvisable to proceed with completion of the sale of and payment for the Shares as provided in this Agreement; or (e) trading in any of the equity securities of the Company shall have been suspended by the Commission, by an exchange that lists the Shares or by the Nasdaq Stock Market. Any termination pursuant to this Section 15 shall be without liability on the part of any Underwriter to the Company or on the part of the Company to any Underwriter (except for expenses to be paid by the Company pursuant to Section 8 or reimbursed by the Company pursuant to Section 10 and except as to indemnification to the extent provided in Section 12). SECTION 16. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The respective indemnities, agreements, representations, warranties, covenants and other statements of the Company or its officer or directors and of the several Underwriters set forth in or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (a) any investigation made by or on behalf of any Underwriter, the Company or any of its or their partners, officers, directors, or any controlling person, as the case may be; (b) any termination of this Agreement; and (c) delivery of and payment for the Shares sold hereunder. SECTION 17. NOTICES. All communications hereunder shall be in writing and, if sent to the Representatives, shall be mailed, delivered, telecopied (with receipt confirmed) or -38- telegraphed and confirmed to Advest, Inc. at One Commercial Plaza, 280 Trumbull Street, Hartford, Connecticut 06103, Attention: Roger E.

SECTION 18. SUCCESSORS. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns, and to the benefit of the officers and directors (and their personal representatives and controlling persons referred to in Section 12), and no other person shall acquire or have any right or obligation hereunder. The term successors and assigns shall not include any purchaser of the Shares as such from any of the Underwriters merely by reason of such purchase. SECTION 19. PARTIAL UNENFORCEABILITY. If any Section, subsection, clause or provision of this Agreement is for any reason determined to be invalid or unenforceable, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or provision is invalid, illegal or incapable of being enforced, the parties thereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible. SECTION 20. WAIVER OF JURY TRIAL. The Company and the Underwriters each hereby waive any right they may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or any of the transactions contemplated hereby. SECTION 21. APPLICABLE LAW. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York. No doctrine of choice of law shall be used to apply any law other than that of the State of Connecticut, and no defense, counterclaim or right of set-off given or allowed by the laws of any other state jurisdiction, or arising out of the enactment, modification or repeal of any law, regulation, ordinance or decree of any foreign jurisdiction, shall be interposed in any action upon or relating to this Agreement. SECTION 22. ENTIRE AGREEMENT.

SECTION 23. COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together constitute one and the same instrument. -39- SECTION 24.
