Dear Sirs:

1. Introduction. OXiGENE, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the purchasers, pursuant to the terms and conditions of this Placement Agent Agreement (this “Agreement”) and the Subscription Agreements in the form of Exhibit A attached hereto (the “Subscription Agreements”) entered into with the purchasers identified therein (each a “Purchaser” and collectively, the “Purchasers”), up to an aggregate of 6,250,000 units (the “Units”) with each Unit consisting of (i) one share (a “Share,” collectively, the “Shares”) of common stock, $0.01 par value per share (the “Common Stock”) of the Company, (ii) one warrant to purchase 0.45 shares of Common Stock (a “Series I Warrant”) and (iii) one warrant (the “Series II Warrant”, and together with the Series I Warrant, the “Warrants”) to purchase up to 0.45 shares of Common Stock, for an aggregate purchase price of $10,000,000 (the “Purchase Price”). The terms and conditions of the Warrants are set forth in the forms of Exhibit B-1 and Exhibit B-2 attached hereto. The Units will not be issued or certificated. The Shares and Warrants are immediately separable and will be issued separately. The shares of Common Stock issuable upon exercise of the Warrants are referred to herein as the “Warrant Shares” and, together with the Units, the Shares and the Warrants, are referred to herein as the “Securities.” The Company hereby confirms its agreement with Lazard Capital Markets LLC (“LCM”) and Xxxxxxxx Curhan Ford & Co. (“Xxxxxxxx”, together with LCM, the “Placement Agents”) to act as Placement Agents in accordance with the terms and conditions hereof. LCM is acting as the representative of the Placement Agents and in such capacity is hereinafter referred to as the “Representative.”

2. Agreement to Act as Placement Agents; Placement of Securities. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement:

2.1 The Company has authorized and hereby acknowledges that the Placement Agents have acted as its exclusive agents to solicit offers for the purchase of all or part of the Units from the Company in connection with the proposed offering of the Units (the “Offering”). Until the Closing Date (as defined in Section 4 hereof) or earlier upon the termination of this Agreement pursuant to Section 9, the Company shall not, without the prior written consent of the Representative, solicit or accept offers to purchase Units otherwise than through the Placement Agents. LCM may utilize the expertise of Lazard Frères & Co. LLC in connection with LCM’s placement agent activities.

2.2 The Company hereby acknowledges that the Placement Agents, as agents of the Company, used their best efforts to solicit offers to purchase the Units from the

Company on the terms and subject to the conditions set forth in the Prospectus (as defined below). The Placement Agents shall use commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Units was solicited by the Placement Agents and accepted by the Company, but the Placement Agents shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any potential purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason. Under no circumstances will the Placement Agents be obligated to underwrite or purchase any Units for their own accounts and, in soliciting purchases of Units, the Placement Agents acted solely as the Company’s agents and not as principals. Notwithstanding the foregoing and except as otherwise provided in Section 2.3, it is understood and agreed that the Placement Agents (or their affiliates) may, solely at their discretion and without any obligation to do so, purchase Units as principals.

2.3 Subject to the provisions of this Section 2, offers for the purchase of Units were solicited by the Placement Agents as agents for the Company at such times and in such amounts as the Placement Agents deem advisable. Each Placement Agent shall communicate to the Company, orally or in writing, each reasonable offer to purchase Units received by it as agent of the Company. The Company shall have the sole right to accept offers to purchase the Units and may reject any such offer, in whole or in part. Each Placement Agent shall have the right, in its discretion reasonably exercised, without notice to the Company, to reject any offer to purchase Units received by it, in whole or in part, and any such rejection shall not be deemed a breach of this Agreement.

2.4 The Units are being sold to the Purchasers at a price of $1.60 per Unit. The purchases of the Units by the Purchasers shall be evidenced by the execution of Subscription Agreements by each of the Purchasers and the Company.

2.5 As compensation for services rendered, on the Closing Date (as defined in Section 4 hereof), the Company shall pay to the Placement Agents by wire transfer of immediately available funds to an account or accounts designated by the Representative, an aggregate amount equal to six and one half percent (6.5%) (the “Placement Fee”) of the gross proceeds received by the Company from the sale of the Units on such Closing Date.

2.6 No Units which the Company has agreed to sell pursuant to this Agreement and the Subscription Agreements shall be deemed to have been purchased and paid for, or sold by the Company, until such Units shall have been delivered to the Purchaser thereof against payment by such Purchaser. If the Company shall default in its obligations to deliver Units to a Purchaser whose offer it has accepted, the Company shall indemnify and hold the Placement Agents harmless against any loss, claim, damage or expense arising from or as a result of such default by the Company in accordance with the procedures set forth in Section 8(c) herein.

3. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Placement Agents and the Purchasers that:

(w) Except as may be disclosed in the General Disclosure Package or the Prospectus, the Company possesses all material licenses, certificates, permits, consents, orders, approvals and authorizations from United States and foreign government authorities, including, without limitation, the Food and Drug Administration (the “FDA”) and any agency of any foreign government and any other foreign regulatory authority exercising authority comparable to that of the FDA (including any non-governmental entity whose approval or authorization is required under foreign law comparable to that administered by the FDA) (each a “Permit”) that are necessary to the ownership of the Company’s property or to the conduct of its business in the manner and to the extent now conducted. Each issued Permit is currently in full force and effect, and no proceeding has been instituted or is pending or, to the best of the Company’s knowledge, is contemplated or threatened, which in any manner adversely affects or draws into question the validity or effectiveness thereof or relates in any way to the revocation or modification thereof.

(x) Except as disclosed in the General Disclosure Package or the Prospectus, (1) each Investigational New Drug application (“IND”) submitted by the Company to the FDA or similar application submitted by the Company to foreign regulatory bodies, and related documents and information, has been submitted and maintained in compliance in all material respects with applicable statutes, rules and regulations administered or promulgated by the FDA or other regulatory body, (2) the studies, tests and preclinical and clinical trials conducted by or on behalf of the Company that are described in the General Disclosure Package or the Prospectus were and, if still pending, are being, conducted, to the best of the Company’s knowledge, in all material respects in accordance with experimental protocols, procedures and controls pursuant to, where applicable, accepted professional and scientific standards for products or product candidates comparable to those being developed by the Company; and the drug substances used in the clinical trials have been manufactured to the best of the Company’s knowledge, under current Good Manufacturing Practices, and (3) the Company uses commercially reasonable efforts to review, from time to time, the progress and results of the studies, tests and preclinical and clinical trials and, based upon (i) the information provided to the Company by the third parties conducting such studies, tests and preclinical and clinical trials that are described in the General Disclosure Package and the Prospectus and the Company’s review of such information, and (ii) the Company’s actual knowledge, the Company reasonably believes that such descriptions of the results of such studies, tests and preclinical and clinical trials are accurate and complete in all material respects. The Company has not received any notices or correspondence from the FDA or any foreign, state or local governmental body exercising comparable authority requiring the termination, suspension or material

modification of any studies, tests or preclinical or clinical trials conducted by or on behalf of the Company.

(y) The Company has made available to counsel to the Placement Agents, FDA and regulatory correspondence logs, and such logs contain complete and accurate descriptions, in all material respects, of all material correspondence between the Company on the one hand and the FDA on the other hand, relating to the clinical trials of the Company’s product candidates under development being conducted under the two (2) Company-sponsored INDs.

(z) The Company has good and marketable title in fee simple to, or has valid rights to lease or otherwise use, all items of real or personal property which are material to the business of the Company, in each case free and clear of all liens, encumbrances, security interests, claims and defects that may result in a Material Adverse Effect.

(aa) No organized labor disturbance by the employees of the Company exists or, to the best of the Company’s knowledge, is imminent which might be expected to have a Material Adverse Effect. The Company is not aware that any key employee or significant group of employees of the Company plans to terminate employment with the Company.

(bb) No “prohibited transaction” (as defined in Section 406 of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”), or Section 4975 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”)) or “accumulated funding deficiency” (as defined in Section 302 of ERISA) or any of the events set forth in Section 4043(b) of ERISA (other than events with respect to which the thirty (30)-day notice requirement under Section 4043 of ERISA has been waived) has occurred or could reasonably be expected to occur with respect to any employee benefit plan of the Company which could, singularly or in the aggregate, have a Material Adverse Effect. Each employee benefit plan of the Company is in compliance in all material respects with applicable law, including ERISA and the Code. The Company has not incurred and could not reasonably be expected to incur liability under Title IV of ERISA with respect to the termination of, or withdrawal from, any pension plan (as defined in ERISA). Each pension plan for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified, and nothing has occurred, whether by action or by failure to act, which could, singularly or in the aggregate, cause the loss of such qualification.

(cc) The Company is in compliance with all foreign, federal, state and local rules, laws and regulations relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection of health and safety or the environment which are applicable to its business (“Environmental Laws”), except where the failure to comply would not, singularly or in the aggregate, have a Material

Adverse Effect. There has been no storage, generation, transportation, handling, treatment, disposal, discharge, emission, or other release of any kind of toxic or other wastes or other hazardous substances regulated by Environmental Laws (“Hazardous Substances”) or caused by the Company (or, to the Company’s knowledge, any other entity for whose acts or omissions the Company is or may otherwise be liable) upon any of the property now or previously owned or leased by the Company, or upon any other property, in violation of any law, statute, ordinance, rule, regulation, order, judgment, decree or permit or which would, under any law, statute, ordinance, rule (including rule of common law), regulation, order, judgment, decree or permit, give rise to any liability, except for any violation or liability which would not have, singularly or in the aggregate with all such violations and liabilities, a Material Adverse Effect; and there has been no disposal, discharge, emission or other release of any kind onto such property or into the environment surrounding such property of any Hazardous Substances with respect to which the Company has knowledge, except for any such disposal, discharge, emission, or other release of any kind which would not have, singularly or in the aggregate with all such discharges and other releases, a Material Adverse Effect.

(dd) The Company (i) has timely filed all necessary federal, state, local and foreign tax returns, and all such returns were true, complete and correct, (ii) has paid all federal, state, local and foreign taxes, assessments, governmental or other charges due and payable for which it is liable, including, without limitation, all sales and use taxes and all taxes which the Company is obligated to withhold from amounts owing to employees, creditors and third parties, and (iii) does not have any tax deficiency or claims outstanding or assessed or, to the best of its knowledge, proposed against any of them, except those, in each of the cases described in clauses (i), (ii) and (iii) of this paragraph (dd), that would not, singularly or in the aggregate, have a Material Adverse Effect. The Company has not engaged in any transaction which is a corporate tax shelter or which could be characterized as such by the Internal Revenue Service or any other taxing authority. The Company reasonably believes that the accruals and reserves on the books and records of the Company in respect of tax liabilities for any taxable period not yet finally determined are adequate to meet any assessments and related liabilities for any such period, and since December 31, 2007, the Company has not incurred any liability for taxes other than in the ordinary course.

(ee) The Company carries, or is covered by, insurance in such amounts and covering such risks as it reasonably believes to be adequate for the conduct of its business and the value of its properties and as it reasonably believes to be customary for companies engaged in similar businesses in similar industries.

(ff) The Company maintains a system of internal accounting and other controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the

General Disclosure Package, since the end of the Company’s most recent audited fiscal year, there has been (A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (B) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(gg) The minute books of the Company have been made available to the Placement Agents and counsel for the Placement Agents, and such books (i) contain a complete summary of all meetings and actions of the board of directors (including each board committee, with the exception of the meetings of the Ad Hoc Committee, for which no minutes were kept) and shareholders of the Company (or analogous governing bodies and interest holders, as applicable), since December 2006 through the date of the latest meeting and action, and (ii) accurately in all material respects reflect all transactions referred to in such minutes.

(hh) There is no franchise, lease, contract, agreement or document required by the Securities Act or by the Rules and Regulations to be described in the General Disclosure Package and in the Prospectus or a document incorporated by reference therein or to be filed as an exhibit to the Registration Statement or a document incorporated by reference therein which is not described or filed therein as required; and all descriptions of any such franchises, leases, contracts, agreements or documents contained in the Registration Statement or in a document incorporated by reference therein are accurate and complete descriptions of such documents in all material respects. Other than as described in the General Disclosure Package, no such franchise, lease, contract or agreement has been suspended or terminated for convenience or default by the Company or any of the other parties thereto, and the Company has not received notice nor does the Company have any other knowledge of any such pending or threatened suspension or termination, except for such pending or threatened suspensions or terminations that would not reasonably be expected to, singularly or in the aggregate, have a Material Adverse Effect.

(ii) No relationship, direct or indirect, exists between or among the Company on the one hand, and the directors, officers, stockholders, customers or suppliers of the Company or any of its affiliates on the other hand, which is required to be described in the General Disclosure Package and the Prospectus or a document incorporated by reference therein and which is not so described, except that, on July 2, 2009, the Company entered into the Symphony Amendment.

(jj) No person or entity has the right to require registration of shares of Common Stock or other securities of the Company because of the filing or effectiveness of the Registration Statement or otherwise, except for persons and entities who have expressly waived such right in writing or who have been given timely and proper written notice and have failed to exercise such right within the time or times required under the terms and conditions of such right. Except as described in the General Disclosure Package, there are no persons with registration rights or similar rights to have any securities registered by the Company under the Securities Act.

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

(ll) Except for this Agreement, the Company is not a party to any contract, agreement or understanding with any person that would give rise to a valid claim against the Company or any Placement Agent for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Units or any transaction contemplated by this Agreement, the Registration Statement, the General Disclosure Package or the Prospectus.

(mm) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in either the General Disclosure Package or the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

(nn) The Company is subject to and in compliance in all material respects with the reporting requirements of Section 13 or Section 15(d) of the Exchange Act. The Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is listed on the Nasdaq GM, and the Company has taken no action designed to, or reasonably likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from the Nasdaq GM, nor, except as set forth in the Company’s Form 8-K filing dated December 30, 2008, has the Company received any notification that the Commission or FINRA is contemplating terminating such registration or listing. No consent, approval, authorization or order of, or filing, notification or registration with, the Nasdaq GM is required for the listing and trading of the Common Stock on the Nasdaq GM except for (i) a Notification: Listing of Additional Shares and (ii) a Notification: Change in the Number of Shares Outstanding.

(oo) The Company is in compliance in all material respects with all applicable provisions of the Xxxxxxxx-Xxxxx Act of 2002 and all rules and regulations promulgated thereunder or implementing the provisions thereof (the “Xxxxxxxx-Xxxxx Act”) that are currently in effect.

(pp) The Company is in compliance in all material respects with all applicable corporate governance requirements set forth in the Nasdaq Marketplace Rules that are currently in effect.

(qq) There are no transactions, arrangements or other relationships between and/or among the Company, any of its affiliates (as such term is defined in Rule 405 of the Securities Act) and any unconsolidated entity, including, but not limited to, any structured finance, special purpose or limited purpose entity that could reasonably be

expected to materially affect the Company’s liquidity or the availability of or requirements for its capital resources required to be described in the General Disclosure Package and the Prospectus or a document incorporated by reference therein which have not been described as required.

(rr) There are no outstanding loans, advances (except normal advances for business expenses in the ordinary course of business) or guarantees or indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of their respective family members, except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus.

(ss) The statistical and market related data included in the Registration Statement, the General Disclosure Package and the Prospectus are based on or derived from sources that the Company believes to be reliable and accurate.

(tt) Neither the Company nor any of its affiliates (within the meaning of FINRA Conduct Rule 2720(b)(1)(a)) directly or indirectly controls, is controlled by, or is under common control with, or is an associated person (within the meaning of Article I, Section 1(ee) of the By-laws of FINRA) of, any member firm of FINRA.

(uu) No approval of the shareholders of the Company under the rules and regulations of Nasdaq (including Rule 5635(d) of the Nasdaq Marketplace Rules) is required for the Company to issue and deliver the Units to the Purchasers.

Any certificate signed by or on behalf of the Company and delivered to the Representative or to counsel for the Placement Agents shall be deemed to be a representation and warranty by the Company to the Placement Agents and the Purchasers as to the matters covered thereby.

4. The Closing. The time and date of closing and delivery of the documents required to be delivered to the Placement Agents pursuant to Sections 5 and 7 hereof shall be at 10:00 A.M., New York time, on July 20, 2009 (the “Closing Date”) at the office of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo P.C., Xxx Xxxxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000.

5. Further Agreements of the Company. The Company agrees with the Placement Agents and the Purchasers:

(a) To prepare the Rule 462(b) Registration Statement, if necessary, in a form approved by the Representative and file such Rule 462(b) Registration Statement with the Commission on the date hereof; to prepare the Prospectus in a form approved by the Representative containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on rules 430A, 430B and 430C and to file such Prospectus pursuant to Rule 424(b) of the Rules and Regulations not later than the second business (2^nd) day following the execution and delivery of this Agreement or, if applicable, such earlier time as may be required by Rule 430A of the Rules and Regulations; to notify the Representative immediately of the Company’s intention to file or prepare any supplement or amendment to any Registration Statement or to the Prospectus and to make no amendment or supplement to the Registration Statement, the

General Disclosure Package or to the Prospectus to which the Representative shall reasonably object by notice to the Company after a reasonable period to review; to advise the Representative, promptly after it receives notice thereof, of the time when any amendment to any Registration Statement has been filed or becomes effective or any supplement to the General Disclosure Package or the Prospectus or any amended Prospectus has been filed and to furnish the Representative with copies thereof; to file promptly all material required to be filed by the Company with the Commission pursuant to Rule 433(d) or 163(b)(2), as the case may be; to file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) of the Rules and Regulations) is required in connection with the offering or sale of the Units; to advise the Representative, promptly after it receives notice thereof, of the issuance by the Commission of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus, of the suspension of the qualification of the Units for offering or sale in any jurisdiction, of the initiation or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement, the General Disclosure Package or the Prospectus or for additional information; and, in the event of the issuance of any stop order or of any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus or suspending any such qualification, and promptly to use its reasonable best efforts to obtain the withdrawal of such order.

(b) The Company represents and agrees that, unless it obtains the prior consent of the Representative, it has not made and will not, make any offer relating to the Units that would constitute a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations unless the prior written consent of the Representative has been received (each, a “Permitted Free Writing Prospectus”); provided that the prior written consent of the Representative hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectus[es] included in Schedule A hereto. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, comply with the requirements of Rules 164 and 433 of the Rules and Regulations applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping and will not take any action that would result in any Placement Agent or the Company being required to file with the Commission pursuant to Rule 433(d) of the Rules and Regulations a free writing prospectus prepared by or on behalf of such Placement Agent that such Placement Agent otherwise would not have been required to file thereunder.

(c) If at any time when a Prospectus relating to the Securities is required to be delivered under the Securities Act, any event occurs or condition exists as a result of which the Prospectus, as then amended or supplemented, would 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, or the Registration Statement, as then amended or supplemented, would include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if for any other reason it is necessary at any time to amend or supplement any Registration Statement or the Prospectus to comply with the Securities Act or the Exchange Act, the Company will promptly notify the Representative, and upon the Representative’s request, the Company will promptly prepare and file with the Commission, at the Company’s expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus that corrects such statement or omission or effects such compliance and will deliver to the Placement Agents, without charge, such number of copies thereof as the Placement Agents may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by the Placement Agents.

(d) If the General Disclosure Package is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Representative, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, or to make the statements therein not conflict with the information contained or incorporated by reference in the Registration Statement then on file and not superseded or modified, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will either (i) prepare, file with the Commission (if required) and furnish to the Placement Agents and any dealers an appropriate amendment or supplement to the General Disclosure Package or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances then prevailing, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

(e) If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or will conflict with the information contained in the Registration Statement, Pricing Prospectus or Prospectus, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof and not superseded or modified or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances prevailing at the subsequent time, not misleading, the Company has promptly notified or will promptly notify the Representative so that any use of the Issuer Free Writing Prospectus may cease until it is amended or supplemented and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon, and in conformity with, written information furnished to the Company by any Placement Agent specifically for inclusion therein,

which information the parties hereto agree is limited to the Placement Agents’ Information (as defined in Section 17).

(f) To the extent not available on the Commission’s XXXXX system or any successor system, to furnish promptly to the Placement Agents and to counsel for the Placement Agents a signed copy of the Registration Statement as originally filed with the Commission, and of each amendment thereto filed with the Commission, including all consents and exhibits filed therewith.

jurisdiction in which it is not so qualified or to file a general consent to service of process in any jurisdiction.

(j) To the extent not available on the Commission’s XXXXX system or any successor system, upon request, during the period of two (2) years from the date hereof, to deliver to the Placement Agents, (i) upon request, copies of all reports or other communications furnished to shareholders, and (ii) upon request, copies of any reports and financial statements furnished or filed with the Commission or any national securities exchange or automatic quotation system on which the Company’s securities are listed or quoted.

The Company also agrees that during such period, the Company will not file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the Securities Act for any such transaction or which registers, or offers for sale, Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, except for a registration statement on Form S-8 relating to employee benefit plans, except for (1) a post-effective amendment to the Registration Statement or Form S-1 (Reg.

Company occurs, during the last seventeen (17) days of the Lock-Up Period, or (ii) if prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this paragraph (k) or the letter shall continue to apply until the expiration of the eighteen (18)-day period beginning on the date of issuance of the earnings release or the occurrence of the material news or material event.

(o) Until the Representative shall have notified the Company of the completion of the offering of the Units, that the Company will not, and will cause its affiliated purchasers (as defined in Regulation M under the Exchange Act) not to, either alone or with one or more other persons, bid for or purchase, for any account in which it or any of its affiliated purchasers has a beneficial interest, any Units, or attempt to induce any person to purchase any Units; and not to, and to cause its affiliated purchasers not to, make bids or purchase for the purpose of creating actual, or apparent, active trading in or of raising the price of the Units.

satisfactory to the Representative, to the effect that (x) such counsel has acted as counsel to the Company in connection with the preparation of the Registration Statement, the General Disclosure Package and the Prospectus, and each amendment or supplement thereto made by the Company prior to the Closing Date, (y) based on such counsel’s examination of the Registration Statement, the General Disclosure Package and the Prospectus, and each amendment or supplement thereto made by the Company prior to the Closing Date and the documents incorporated by reference in the General Disclosure Package or the Prospectus and any further amendment or supplement to any such incorporated document made by the Company prior to the Closing Date, and such counsel’s investigations made in connection with the preparation of the Registration Statement, the General Disclosure Package and the Prospectus, and each amendment or supplement thereto made by the Company prior to the Closing Date, and conferences with certain officers and employees of and with auditors for the Company as well as the Placement Agents and counsel to the Placement Agents, nothing has come to such counsel’s attention that has led it to believe that (I) the Registration Statement or any amendment thereto as of its effective date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus or any amendment or supplement thereto, at the respective date thereof or at the Closing Date, contained or contains any untrue statement of a material fact or omits 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, the documents included in the General Disclosure Package, all considered together, as of the Applicable Time, contained or contains any untrue statement of a material fact or omits 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, or (II) any document incorporated by reference in the Prospectus or any further amendment or supplement to any such incorporated document made by the Company prior to the Closing Date, when they became effective or were filed with the Commission, as the case may be, contained, in the case of a registration statement which became effective under the Securities Act, any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, or, in the case of other documents which were filed under the Exchange Act with the Commission, any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; it being understood that such counsel need express no opinion as to the financial statements, schedules or other financial, statistical or accounting data contained in the Registration Statement, the General Disclosure Package, or the Prospectus, or an incorporated document. The foregoing statement may be qualified by a statement to the effect that such counsel has not independently verified the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus and is not passing upon and takes no responsibility therefor except to the extent set forth in the opinion described above.

(a) The Company shall indemnify and hold harmless each Placement Agent, each of its affiliates and each of its and their respective directors, officers, members, employees, representatives and agents (including, without limitation Lazard Frères & Co. LLC, (which will provide services to LCM) and its affiliates, and each of its and their respective directors, officers, members, employees, representatives and agents and each person, if any, who controls Lazard Frères & Co. LLC within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and each person, if any, who controls such Placement Agent within the meaning of Section 15 of the Securities Act

or Section 20 of the Exchange Act (collectively the “Placement Agent Indemnified Parties,” and each a “Placement Agent Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Placement Agent Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, or (B) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto or document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein not misleading (C) any breach of the representations and warranties of the Company contained herein or failure of the Company to perform its obligations hereunder or pursuant to any law, any act or failure to act, or any alleged act or failure to act, by any Placement Agent in connection with, or relating in any manner to, the Units, the Escrow Agreement or the Offering, and which is included as part of or referred to in any loss, claim, damage, expense, liability, action, investigation or proceeding arising out of or based upon matters covered by subclause (A), (B) or (C) above of this Section 8(a) (provided that the Company shall not be liable in the case of any matter covered by this subclause (C) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, expense or liability resulted directly from any such act, or failure to act, undertaken or omitted to be taken by any Placement Agent through its gross negligence or willful misconduct), and shall reimburse the Placement Agent Indemnified Party promptly upon demand for any documented legal fees or other expenses reasonably incurred and documented by that Placement Agent Indemnified Party in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, expense or liability arises out of or is based upon an untrue statement or alleged untrue statement in, or omission or alleged omission from any Preliminary Prospectus, any Registration Statement or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by the Representative by or on behalf of any Placement Agent specifically for use therein, which information the parties hereto agree is limited to the Placement Agents’ Information (as defined in Section 17). This indemnity agreement is not exclusive and will be in addition to any liability, which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Placement Agent Indemnified Party.

(b) Each Placement Agent, severally and not jointly, shall indemnify and hold harmless the Company and its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively the “Company Indemnified Parties” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the 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 the Representative by or on behalf of any Placement Agent specifically for use therein, which information the parties hereto agree is limited to the Placement Agents’ Information (as defined in Section 17), and shall reimburse the Company for any documented legal fees or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. Notwithstanding the provisions of this Section 8(b), in no event shall any indemnity by any Placement Agent under this Section 8(b) exceed the total compensation received by such Placement Agent in accordance with Section 2.5.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify such indemnifying party in writing of the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, except as provided

herein, the indemnifying party shall not be liable to the indemnified party under Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the reasonable, documented fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 8(a) or Section 2.6 or LCM in the case of a claim for indemnification under Section 8(b), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action; provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable documented fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by LCM if the indemnified parties under this Section 8 consist of any Placement Agent Indemnified Party or by the Company if the indemnified parties under this Section 8 consist of any Company Indemnified Parties. Subject to this Section 8(c), the amount payable by an indemnifying party under Section 8 shall include, but not be limited to, (x) reasonable, documented legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such 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. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or

any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, if its consent has been unreasonably withheld or delayed or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or Section 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agents on the other hand from the offering of the Units, or (ii) if the allocation provided by clause (i) of this Section 8(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 8(d) but also the relative fault of the Company on the one hand and the Placement Agents on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agents on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Company bear to the total Placement Fee received by the Placement Agents in connection with the Offering, 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 Placement Agents 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 Company on the one hand or the Placement Agents on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by the Representative by and on behalf of the Placement Agent for use in any Preliminary Prospectus, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Placement Agents’ Information as defined in Section 17. The Company and the Placement Agents agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined

by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of this Section 8(d), no Placement Agent shall be required to contribute any amount in excess of the total compensation received by such Placement Agent in accordance with Section 2.5 less the amount of any damages which such Placement Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Placement Agents’ obligations to contribute as provided in this Section 8(d) are several in proportion to the amount of the Placement Fee received by each of them and not joint.

9. Termination. The obligations of the Placement Agents and the Purchasers hereunder and under the Subscription Agreements may be terminated by the Representative, in its absolute discretion by notice given to the Company prior to delivery of and payment for the Units if, prior to that time, any of the events described in Sections 7(j), 7(k) and 7(l) have occurred or if the Purchasers shall decline to purchase the Units for any reason permitted under this Agreement or the Subscription Agreements.

10. Reimbursement of Placement Agents’ Expenses. Notwithstanding anything to the contrary in this Agreement, if (a) this Agreement shall have been terminated pursuant to Section 9, (b) the Company shall fail to tender the Units for delivery to the Purchasers for any reason not permitted under this Agreement, (c) the Purchasers shall decline to purchase the Units for any reason permitted under this Agreement or (d) the sale of the Units is not consummated because any condition to the obligations of the Purchasers or the Placement Agents set forth herein is not satisfied or because of the refusal, inability or failure on the part of the Company to perform any agreement herein or to satisfy any condition or to comply with the provisions hereof, then in addition to the payment of amounts in accordance with Section 6, the Company shall reimburse the Placement Agents for the reasonable, documented fees and expenses of the Placement Agents’ counsel and for such other accountable out-of-pocket expenses as shall have been reasonably incurred by them in connection with this Agreement and the proposed purchase of the Units, and upon demand the Company shall pay the full amount thereof to the Placement Agents.

11. Authority of the representative. Xxxxxxxx consents and agrees that LCM will act as Representative of the Placement Agents under this Agreement and with respect to the sale of the Units. Accordingly, Xxxxxxxx authorizes LCM to manage the Offering and the sale of the Units and to take such action in connection therewith as LCM in its sole discretion deems appropriate or desirable, consistent with the provisions of each Agreement Among Underwriters

previously entered into between LCM and Xxxxxxxx, respectively, taking into account that the Offering of the Units will be in the form of a best efforts placement and not a firm commitment underwriting. Xxxxxxxx agrees to comply with such Agreement Among Underwriters and that any action taken under this Agreement by the Representative shall be binding upon all of the Placement Agents.

12. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) the Placement Agents’ responsibility to the Company is solely contractual in nature, the Placement Agents have been retained solely to act as placement agents in connection with the Offering and no fiduciary, advisory or agency relationship between the Company and the Placement Agents has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Placement Agents or Lazard Frères & Co. LLC have advised or are advising the Company on other matters;

(b) the price of the Units set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Placement Agents, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) it has been advised that the Placement Agents and Lazard Frères & Co. LLC and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Placement Agent have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) it waives, to the fullest extent permitted by law, any claims it may have against the Placement Agents for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Placement Agents shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

13. Successors; Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Placement Agents, the Company, and their respective successors and assigns. This Agreement shall also inure to the benefit of Lazard Frères & Co. LLC, the Purchasers, and each of their respective successors and assigns, which shall be third party beneficiaries hereof. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, other than the persons mentioned in the preceding sentences, any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person; except that the representations, warranties, covenants, agreements and indemnities of the Company contained in this Agreement shall also be for the benefit of the

Placement Agent Indemnified Parties and the indemnities of each Placement Agent shall be for the benefit of the Company Indemnified Parties. It is understood that the Placement Agents’ responsibility to the Company is solely contractual in nature and the Placement Agents do not owe the Company, or any other party, any fiduciary duty as a result of this Agreement.

14. Survival of Indemnities, Representations, Warranties, etc. The respective indemnities, covenants, agreements, representations, warranties and other statements of the Company and the Placement Agents, as set forth in this Agreement or made by them respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation made by or on behalf of the Placement Agents, the Company, the Purchasers or any person controlling any of them and shall survive delivery of and payment for the Units. Notwithstanding any termination of this Agreement, including without limitation any termination pursuant to Sections 9 or 10, the indemnity and contribution agreements contained in Section 8 and the covenants, representations, warranties set forth in this Agreement shall not terminate and shall remain in full force and effect at all times.
