Ladies and Gentlemen:

OXiGENE, Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions contained herein, to issue and sell shares (the “Shares”) of common stock, $0.01 par value per share (the “Common Stock”), directly to certain investors (collectively, the “Investors”). The Company desires to engage you as its placement agents (the “Placement Agents”) in connection with such issuance and sale. The Shares are more fully described in the Registration Statement (as hereinafter defined).

The Company has prepared and filed in conformity with the requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the published rules and regulations thereunder (the “Rules”) adopted by the Securities and Exchange Commission (the “Commission”), a Registration Statement (as hereinafter defined) on Form S-3 (No. 333-109433), including a base prospectus relating to the Shares (the “Base Prospectus”) and such amendments thereof as may have been required to the date of this Agreement. Copies of such Registration Statement (including all amendments thereof) and of the related Base Prospectus (as hereinafter defined) have heretofore been delivered by the Company to you. The term “Registration Statement” as used in this Agreement means the initial registration statement (including all exhibits, financial schedules and all documents and information deemed to be a part of the Registration Statement through incorporation by reference or otherwise)), as amended

at the time and on the date it became effective (the “Effective Date”), including the information (if any) contained in the form of final prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and deemed to be part thereof at the time of effectiveness pursuant to Rule 430A of the Rules. If the Company has filed an abbreviated registration statement to register additional Shares pursuant to Rule 462(b) under the Rules (the “462(b) Registration Statement”), then any reference herein to the Registration Statement shall also be deemed to include such 462(b) Registration Statement. The prospectus supplement relating to the Shares as filed with the Commission pursuant to and in accordance with Rule 424(b) under the Securities Act is hereinafter referred to as the “Prospectus Supplement.” The term “Prospectus” as used in this Agreement means the Base Prospectus together with the Prospectus Supplement. As used herein, the terms “Base Prospectus,” “Prospectus,” “Registration Statement,” “462(b) Registration Statement,” and “Prospectus Supplement” shall include any documents incorporated by reference therein, and any reference to any amendment or supplement to the Registration Statement or the Prospectus shall be deemed to refer to and include any documents filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the date of the Base Prospectus by the Company with the Commission, that are deemed to be incorporated by reference in the Prospectus.

The Company hereby confirms that the Placement Agents, in connection with their duties in such capacity, are authorized to distribute or cause to be distributed the Prospectus (as from time to time amended or supplemented if the Company furnishes amendments or supplements thereto to the Placement Agents).

1. Agreement to Act as Placement Agents, Delivery and Payment. On the basis of the representations, warranties and agreements contained in, and subject to the terms and conditions of, this Agreement:

(a) The Placement Agents agree to act as the Company’s exclusive placement agents in connection with the issuance and sale, on a reasonable efforts basis, by the Company of the Shares to the Investors. The Company acknowledges and agrees that the Placement Agents’ engagement hereunder is not an agreement by the Placement Agents or any of their affiliates to underwrite or purchase any securities or otherwise provide any financing. As compensation for their services hereunder, the Company agrees to pay on the Closing Date (as defined below) to the Placement Agents by wire transfer of immediately available funds 7% of the proceeds received by the Company from the sale of the Shares.

(b) Payment of the purchase price for, and delivery of the Shares shall be made at a closing (the “Closing”) at the offices of Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP, at 9:00 a.m., New York time, on the Closing Date to take place on the third or fourth business day (as permitted under Rule 15c6-1 under the Exchange Act) after the determination of the sales price of the Shares (such time and date of payment and delivery being herein called the “Closing Date”). All actions taken at the Closing shall be deemed to have occurred simultaneously.

(c) Payment of the purchase price for the Shares shall be made by the Investors directly to or upon the order of U.S. Bank National Association, as escrow agent (the

“Escrow Agent”) by wire transfer in immediately available funds to the Escrow Agent, upon delivery of the Shares through the facilities of The Depository Trust Company, to the Investors, and shall be registered in such name or names and shall be in such denominations, as the Investors may request at least one business day before the Closing Date.

(d) The several purchases of the Shares by the Investors shall be evidenced by the execution of one or more purchase agreements each substantially in the form attached hereto as Exhibit A (the “Purchase Agreement”).

(e) Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date, the Company shall not, without the prior consent of the Placement Agents, solicit or accept offers to purchase Shares (other than pursuant to the exercise of options or warrants to purchase shares of Common Stock that are outstanding at the date hereof) otherwise than through the Placement Agents.

2. Representations and Warranties of the Company. The Company represents and warrants to each Placement Agent as of the date hereof, and as of the Closing Date, as follows:

(a) The Company meets the requirements for use of Form S-3 under the Securities Act. On the Effective Date, the Registration Statement complied, and on the date of the Prospectus, the date any post-effective amendment to the Registration Statement becomes effective, the date any supplement or amendment to the Prospectus is filed with the Commission and the Closing Date, the Registration Statement and the Prospectus (and any amendment thereof or supplement thereto) will comply, in all material respects, with the requirements of the Securities Act and the Rules and the Exchange Act and the rules and regulations of the Commission thereunder. The Registration Statement did not, as of the Effective Date, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the Effective Date and the other dates referred to in the second sentence of this paragraph 2(a) above, neither the Registration Statement nor the Prospectus, nor any amendment thereof or supplement thereto, will contain any untrue statement of a material fact or will omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading. If applicable, when any related preliminary prospectus was first filed with the Commission (whether filed as part of the Registration Statement or any amendment thereto or pursuant to Rule 424(b) of the Rules) and when any amendment thereof or supplement thereto was first filed with the Commission, such preliminary prospectus as amended or supplemented complied in all material respects with the applicable provisions of the Securities Act and the Rules and did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading. If applicable, each preliminary prospectus and the Prospectus delivered to the Placement Agents for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T. If Rule 434 is used, the Company will comply with the requirements of

Rule 434 and the Prospectus shall not be “materially different,” as such term is used in Rule 434, from the Prospectus included in the Registration Statement at the time it became effective. Notwithstanding the foregoing, none of the representations and warranties in this paragraph 2(a) shall apply to statements in, or omissions from, the Registration Statement or the Prospectus made in reliance upon, and in conformity with, information herein or otherwise furnished in writing by the Placement Agents for use in the Registration Statement or the Prospectus.

(b) The Registration Statement is effective under the Securities Act, and no stop order preventing or suspending the effectiveness of the Registration Statement or suspending or preventing the use of the Prospectus has been issued by the Commission and, to the Company’s knowledge, no proceedings against the Company for that purpose have been instituted or are threatened under the Securities Act. Any required filing of the Prospectus and any supplement thereto pursuant to Rule 424(b) of the Rules has been or will be made in the manner and within the time period required by such Rule 424(b).

(c) The documents incorporated by reference in the Registration Statement and the Prospectus, at the time they became effective or were filed with the Commission, as the case may be, complied in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder, and at the time they became effective or were filed with the Commission, as the case may be, none of such documents contained an untrue statement of a material fact or omitted 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 under which they were made, not misleading, and any further documents so filed and incorporated by reference in the Registration Statement and the Prospectus, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

(d) The financial statements of the Company (including all notes and schedules thereto) included or incorporated by reference in the Registration Statement and Prospectus present fairly, in all material respects, the financial position of the Company at the dates indicated and the statement of operations, stockholders’ equity and cash flows of the Company for the periods specified; and such financial statements and related schedules and notes thereto, and the unaudited financial information filed with the Commission as part of the Registration Statement, have been prepared in conformity with generally accepted accounting principles, consistently applied throughout the periods involved (except as otherwise stated therein and subject, in the case of unaudited financial statements, to the absence of footnotes and normal year-end adjustments). The selected financial data included in the Prospectus present fairly, in all material respects, the information shown therein as at the respective dates and for the respective periods specified and have been presented on a basis consistent with the consolidated financial statements set forth in the Prospectus and other financial information.

(e) Ernst & Young LLP (“E&Y”), whose reports are filed with the Commission as a part of the Registration Statement, are and, during the periods covered by their reports, were independent public accountants with respect to the Company as required by the Securities Act and the Rules.

(f) The Company is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation. The Company has no subsidiary or subsidiaries and does not control, directly or indirectly, any corporation, partnership, joint venture, association or other business organization. The Company is duly qualified to do business and is in good standing as a foreign entity in each jurisdiction in which the nature of the business conducted by it or location of the assets or properties owned, leased or licensed by it requires such qualification, except for such jurisdictions where the failure to so qualify individually or in the aggregate would not have a material adverse effect on the assets, properties, condition, financial or otherwise, or the results of operations of the Company considered as a whole (a “Material Adverse Effect”); and to the Company’s knowledge, no proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification. Except as disclosed in the Prospectus, the Company does not own, lease or license any material asset or property or conduct any material business, other than clinical trials, outside the United States of America

(g) The Company has all requisite corporate power and authority, and all necessary authorizations, approvals, consents, orders, licenses, certificates and permits of and from all governmental or regulatory bodies or any other person or entity (collectively, the “Permits”), to own, lease and license its assets and properties and conduct its business, all of which are valid and in full force and effect, except where the lack of such Permits, individually or in the aggregate, would not have a Material Adverse Effect. The Company has fulfilled and performed in all material respects all of its material obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof, or results in any other impairment of the rights of the Company thereunder, except where such revocation, termination or impairment would not have a Material Adverse Effect. Except as may be required under the Securities Act, state and foreign Blue Sky laws, and by the rules of the National Association of Securities Dealers, Inc. (the “NASD”), no other Permits are required to enter into, deliver and perform this Agreement and each Purchase Agreement and to issue and sell the Shares.

(h) Since the respective dates as of which information is given in the Prospectus, (i) all of the descriptions of the Company’s legal and governmental proceedings and procedures before the United States Food and Drug Administration (the “FDA”), the European Medicines Evaluation Agency (the “EMEA”) or any other national, departmental, state or local governmental body exercising comparable authority are true and correct in all material respects, (ii) all of the description of the studies, tests and preclinical and clinical trials conducted by or on behalf of the Company were and, if still pending, are being conducted in accordance with experimental protocols, procedures and controls pursuant to, where applicable, accepted professional scientific standards (which statements are made to the Company’s knowledge after due inquiry with respect to all

such studies, tests and preclinical and clinical trials that are being conducted on its behalf or independently by others using the Company’s drug candidates); (iii) the descriptions of the results of such studies, tests and trials are true and correct in all material respects (which statements are made to the Company’s knowledge after due inquiry with respect to all such studies, tests and preclinical and clinical trials that are being conducted on its behalf or independently by others using the Company’s drug candidates); and (iv) except as disclosed in the Prospectus, the Company has not received any notices or correspondence from the FDA, or any national, 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.

(i) To the best of the Company’s knowledge, after due inquiry, the Company owns or possesses adequate rights to use all patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property necessary to carry on the business now operated by it with respect to the Company’s currently contemplated combretastatin products for ophthalmic and oncology uses as described in the Company’s Form 10-K and the Prospectus Supplement (collectively, “Intellectual Property”), except where the lack of such ownership or rights would not have a Material Adverse Effect. Except as disclosed in the Prospectus, there is no litigation or other proceeding pending or, to the Company’s knowledge, threatened and no claims are presently being asserted by any third party challenging or questioning the ownership, validity, or enforceability of the Company’s right to use or own any Intellectual Property or asserting that the use of any Intellectual Property by the Company or the operation of the business of the Company infringes upon or misappropriates the Intellectual Property of any third party, other than infringements which would not be reasonably likely to have a Material Adverse Effect, and the Company is not otherwise aware of any infringement of or conflict with asserted rights of others with respect to any of the Company’s Intellectual Property or of any facts or circumstances which would render any of the Company’s Intellectual Property invalid or inadequate to protect the interest of the Company therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate, would result in a Material Adverse Effect.

(j) The Company has good and marketable title in fee simple to all real property, and good and marketable title to all other personal property owned by it, in each case free and clear of all liens, encumbrances, claims, security interests and defects, except such as do not materially affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company. All property held under lease by the Company is held by it under valid, existing and enforceable leases, free and clear of all liens, encumbrances, claims, security interests and defects, except such as are not material and do not materially interfere with the use made or proposed to be made of such property by the Company. Subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus, (i) there has not been any Material Adverse Effect; (ii) the Company has not sustained any loss or interference with its assets, businesses or properties (whether owned or leased) from fire,

explosion, earthquake, flood or other calamity, whether or not covered by insurance, or from any labor dispute or any court or legislative or other governmental action, order or decree, in any such case that would have a Material Adverse Effect; and (iii) since the date of the latest balance sheet included or incorporated by reference in the Registration Statement and the Prospectus, the Company has not (A) issued any securities except for shares of Common Stock of the Company issued upon the exercise or conversion of securities exercisable for, or convertible into, shares of Common Stock outstanding on the date of such balance sheet or incurred any liability or obligation, direct or contingent, for borrowed money, except such liabilities or obligations incurred in the ordinary course of business, (B) entered into any transaction not in the ordinary course of business or (C) declared or paid any dividend or made any distribution on any shares of its stock or redeemed, purchased or otherwise acquired or agreed to redeem, purchase or otherwise acquire any shares of its capital stock.

Each description of a contract, document or other agreement in the Registration Statement and the Prospectus accurately reflects in all material respects the terms of the underlying contract, document or other agreement. Each contract, document or other agreement described in the Registration Statement and Prospectus or listed in the exhibits to the Registration Statement or incorporated by reference is in full force and effect and is valid and enforceable by and against the Company in accordance with its terms. Neither the Company nor, to the Company’s knowledge, any other party is in default in the observance or performance of any term or obligation to be performed by it under any such agreement or any other agreement or instrument to which the Company is a party or by which Company or its properties or business may be bound, and no event has occurred which with notice or lapse of time or both would constitute such a default, in any such case in which the default or event, individually or in the aggregate, would have a Material Adverse Effect.

(m) The Company is not in violation of any term or provision of its charter, by-laws or of any franchise, license, permit, judgment, decree, order, statute, rule or regulation, where the consequences of such violation, individually or in the aggregate, would have a Material Adverse Effect.

(o) Neither the execution, delivery and performance of this Agreement by the Company nor the consummation of any of the transactions contemplated hereby (including, without limitation, the issuance and sale by the Company of the Shares) will (a) give rise to a right to terminate or accelerate the due date of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default

(or an event which with notice or lapse of time or both would constitute a default) under, or require any consent or waiver under, or result in the execution or imposition of any lien, charge or encumbrance upon any properties or assets of the Company pursuant to the terms of, (i) any indenture, mortgage, deed of trust or other agreement or instrument to which the Company is a party or by which the Company or any of its properties or businesses is bound, or (ii) any franchise, license, permit, judgment, decree, order, statute, rule or regulation applicable to the Company, or (b) violate any provision of the charter or by-laws of the Company except for such consents or waivers which have already been obtained and are in full force and effect, and except in the case of clause (a) above, for any such right, conflict, breach, default or other consequence that would not, individually or in the aggregate, have a Material Adverse Effect.

(v) The Company has filed all Federal, state, local and foreign tax returns which are required to be filed through the date hereof, which returns are true and correct in all material respects, or has received timely extensions thereof, and has paid all taxes shown on such returns and all assessments received by it to the extent that the same are material and have become due and are not being contested in good faith.

(nn) 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 Placement Agents for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Shares.

4. Covenants of the Company.

(a) The Company covenants and agrees as follows:

(i) The Company shall prepare the Prospectus in a form approved by the Placement Agents and file such Prospectus pursuant to Rule 424(b) under the Securities Act not later than the Commission’s close of business on the second business day following the execution and delivery of this Agreement, or, if applicable, such earlier time as may be required by the Rules.

(ii) The Company shall promptly advise the Placement Agents in writing, during any period when the Prospectus would be required by law to be delivered in connection with sales of the Shares by an underwriter or dealer in connection with the offering contemplated by this Agreement, (A) when any post-effective amendment to the Registration Statement shall have become effective or any supplement to the Prospectus shall have been filed, (B) of any request by the Commission for any amendment of the Registration Statement or the Prospectus or for any additional information, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the institution or threatening of any proceeding for that purpose and (D) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company shall not, during such period as the Prospectus would be required by law to be delivered in connection with sales of the Shares by an underwriter or dealer in connection with the offering contemplated by this Agreement, file any amendment to the Registration Statement or supplement to the Prospectus or any document incorporated by reference in the Registration Statement unless the Company has furnished the Placement Agents a copy for its review prior to filing and shall not file any such proposed amendment or supplement to which the Placement Agents reasonably object. The Company shall use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(iii) If, at any time when a prospectus relating to the Shares is required to be delivered under the Securities Act and the Rules, any event occurs 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 any material fact

necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend or supplement the Prospectus to comply with the Securities Act or the Rules, the Company promptly shall prepare and file with the Commission, subject to the second sentence of paragraph (ii) of this Section 4(a), an amendment or supplement which shall correct such statement or omission or an amendment which shall effect such compliance.

(iv) The Company shall make generally available to its security holders and to the Placement Agents as soon as practicable, an earning statement which shall satisfy the provisions of Section 11(a) of the Securities Act or Rule 158 of the Rules.

(v) The Company shall furnish to the Placement Agents and counsel for the Placement Agents, without charge, signed copies of the Registration Statement (including all exhibits thereto and amendments thereof) and, so long as delivery of a prospectus by a placement agent or dealer may be required by the Securities Act or the Rules, as many copies of any preliminary prospectus and the Prospectus and any amendments thereof and supplements thereto as the Placement Agents may reasonably request. If applicable, the copies of the Registration Statement and Prospectus and each amendment and supplement thereto furnished to the Placement Agents will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(vi) The Company shall cooperate with the Placement Agents and their counsel in endeavoring to qualify the Shares for offer and sale in connection with the offering under the laws of such jurisdictions as the Placement Agents may designate and shall maintain such qualifications in effect so long as required for the distribution of the Shares; provided, however, that the Company shall not be required in connection therewith, as a condition thereof, to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or subject itself to taxation as doing business in any jurisdiction.

(vii) The Company, during the period when the Prospectus is required to be delivered under the Securities Act and the Rules or the Exchange Act, will file all reports and other documents required to be filed with the Commission pursuant to Section 13, 14 or 15 of the Exchange Act within the time periods required by the Exchange Act and the regulations promulgated thereunder.

(viii) Without the prior written consent of ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ Incorporated, for a period of 90 days after the date of this Agreement (the “Lock-Up Period”), the Company and each of its individual directors and executive officers of the Company shall not issue, sell or register with the Commission (other than on Form S-8 or on any successor form), or otherwise dispose of, directly or indirectly, any equity securities of the Company (or any

securities convertible into, exercisable for or exchangeable for equity securities of the Company), except for (1) the issuance of the Shares pursuant to the Registration Statement, (2) the issuance of shares pursuant to the Company’s existing stock option plan or bonus plan as described in the Registration Statement and the Prospectus, (3) securities required to be issued pursuant to the agreements set forth in Schedule II hereto, and (4) options issued to a person not previously an employee or director of the Company pursuant to the provisions of NASD Marketplace Rule 4350(i)(1)(A)(iv). In the event that during this period, (A) any shares are issued pursuant to the Company’s existing stock option plan or bonus plan that are exercisable during such 90 day period or (B) any registration is effected on Form S-8 or on any successor form relating to shares that are exercisable during such 90 day period, the Company shall obtain the written agreement of such grantee or purchaser or holder of such registered securities that, for a period of 90 days after the date of this Agreement, such person will not, without the prior written consent of ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ Incorporated, offer for sale, sell, distribute, grant any option for the sale of, or otherwise dispose of, directly or indirectly, or exercise any registration rights with respect to, any shares of Common Stock (or any securities convertible into, exercisable for, or exchangeable for any shares of Common Stock) owned by such person. Notwithstanding the foregoing, if (x) during the last 17 days of the Lock-Up Period the Company issues an earnings release or material news or a material event relating to the Company occurs, or (y) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed in this clause shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

(ix) On or before completion of this offering, the Company shall make all filings required under applicable securities laws and by the Nasdaq National Market.

(x) Prior to the earlier of the termination of this Agreement or the Closing Date, the Company will issue no press release or other communications directly or indirectly and hold no press conference with respect to the Company, its condition, financial or otherwise, or its earnings, business affairs or business prospects, or the offering of the Shares without the prior written consent of the Placement Agents, which consent shall not be unreasonably withheld or delayed, unless in the judgment of the Company and its counsel, and after notification to the Placement Agents, such press release or communication is required by law.

(xi) The Company will apply the net proceeds from the offering of the Shares in the manner set forth under “Use of Proceeds” in the Prospectus.

(b) The Company agrees to pay, or reimburse if paid by the Placement Agents, whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, all costs and expenses incident to the performance of the obligations of the

Company under this Agreement including those relating to: (i) the preparation, printing, filing and distribution of the Registration Statement including all exhibits thereto, any preliminary prospectus, the Prospectus, all amendments and supplements to the Registration Statement and the Prospectus and any document incorporated by reference therein, and the printing, filing and distribution of this Agreement; (ii) the preparation and delivery of certificates for the Shares; (iii) the registration or qualification of the Shares for offer and sale under the securities or Blue Sky laws of the various jurisdictions referred to in Section 4(a)(vi), including the reasonable fees and disbursements of counsel for the Placement Agents in connection with such registration and qualification and the preparation, printing, distribution and shipment of preliminary and supplementary Blue Sky memoranda; (iv) the furnishing (including costs of shipping and mailing) to the Placement Agents of copies of any preliminary prospectus, the Prospectus and all amendments or supplements to the Prospectus, and of the several documents required by this Section 4 to be so furnished, as may be reasonably requested for use in connection with the offering and sale of the Shares; (v) the filing fees of the NASD in connection with its review of the terms of the offering and reasonable fees and disbursements of counsel for the Placement Agents in connection with such review; (vi) inclusion of the Shares for quotation on the Nasdaq National Market; (vii) the costs and expenses of the Company relating to investor presentations in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the production of slides and graphics, fees and expenses of any consultants engaged in connection with the presentations, travel and lodging expenses of the representatives and officers of the Company and any such consultants; and (viii) all of reasonable out-of-pocket expenses of the Placement Agents (including reasonable fees and expenses of one legal counsel) in connection with the performance of the services hereunder, provided that such expenses shall not exceed a total of $100,000 without the prior written approval of the Company. Subject to the provisions of Section 7, the Placement Agents agree to pay, whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, all costs and expenses incident to the performance of the obligations of the Placement Agents under this Agreement not payable by the Company pursuant to the preceding sentence.

5. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Placement Agent and each person, if any, who controls any Placement Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee, agent or affiliate of each Placement Agent against any and all losses, claims, damages and liabilities, joint or several (including any reasonable investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the Securities Act, the Exchange Act or other Federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Registration Statement or the Prospectus or any amendment thereof or supplement thereto, or arise out of or are based upon any omission to state therein a material fact required to be stated therein or

necessary to make the statements therein not misleading; provided, however, that such indemnity shall not inure to the benefit of any Placement Agent (or any person controlling such Placement Agent) on account of any losses, claims, damages or liabilities arising from the sale of the Shares if such untrue statement or omission or alleged untrue statement or omission was made in any preliminary prospectus, Registration Statement or the Prospectus, or such amendment or supplement thereto, in reliance upon and in conformity with information furnished in writing to the Company by the Placement Agents on behalf of such Placement Agent specifically for use therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Placement Agent agrees to indemnify and hold harmless the Company, 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, each director of the Company, and each officer of the Company who signs the Registration Statement, against any and all losses, claims, damages and liabilities, joint or several (including any reasonable investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted) to which they, or any of them, may become subject under the Securities Act, the Exchange Act or other Federal or state law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Registration Statement or 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 any preliminary prospectus, the Registration Statement or the Prospectus or any such amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Placement Agent expressly for use therein; provided, however, that the obligation of each Placement Agent to indemnify the Company (including any controlling person, director or officer thereof) shall be limited to the amount of placement agent fees actually received by such Placement Agent pursuant to this Agreement.

(c) Any party that proposes to assert the right to be indemnified under this Section 5 will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 5, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served. No indemnification provided for in Section 5(a) or 5(b) shall be available to any party who shall fail to give notice as provided in this Section 5(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related but the omission to so notify such indemnifying party of any such action, suit or proceeding shall only relieve it from liability to the extent that it was prejudiced by the failure to give such notice and shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under this Section 5. In case

any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and the approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying parties, (ii) the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iii) the indemnifying parties shall not have employed counsel to assume the defense of such action within a reasonable time after notice of the commencement thereof, in each of which cases the fees and expenses of one counsel shall be at the expense of the indemnifying parties. An indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or claim effected without its written consent, which consent shall not be unreasonably withheld or delayed.

6. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 5(a) or 5(b) is due in accordance with its terms but for any reason is unavailable to or insufficient to hold harmless an indemnified party in respect to any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted) incurred by such indemnified party, as incurred, in such proportion as is 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 Shares pursuant to this Agreement or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and the Placement Agents on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The Company and the Placement Agents agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Placement Agents were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or

alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 6, no Placement Agent shall be required to contribute any amount in excess of the amount of placement agent fees actually received by such Placement Agent pursuant to this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person, if any, who controls a Placement Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee, agent or affiliate of each Placement Agent shall have the same rights to contribution as such Placement Agent, and each director of the Company, each officer of the Company 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, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 6, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 6. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Placement Agents’ obligations to contribute pursuant to this Section 6 are several in proportion to the respective amounts of placement agent fees each has actually received pursuant to this Agreement and not joint.

7. Termination.

(a) This Agreement may be terminated at any time prior to the Closing Date by the Placement Agents by notifying the Company at any time at or before the Closing Date in the absolute discretion of the Placement Agents if: (i) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the opinion of the Placement Agents, will in the future materially disrupt, the securities markets, or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States is such as to make it, in the judgment of the Placement Agents, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (ii) there has occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the judgment of the Placement Agents, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (iii) trading in the Shares or any securities of the Company has been suspended or materially limited by the Commission or trading generally on the New York Stock Exchange, Inc., the American Stock Exchange, Inc. or the Nasdaq National Market has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc., or any other governmental or regulatory authority; or (iv) a banking moratorium has been declared by any state or Federal authority; or (v) in the judgment of the Placement Agents, there has

been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the assets, properties, condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company considered as a whole, whether or not arising in the ordinary course of business.

(b) If this Agreement is terminated pursuant to any of its provisions, the Company shall not be under any liability to any Placement Agent, and no Placement Agent shall be under any liability to the Company, except that if this Agreement is terminated by the Placement Agents because of any failure, refusal or inability on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Placement Agents for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) incurred by them in connection with this Agreement and the proposed sale of the Shares or in contemplation of performing their obligations hereunder, which shall not exceed the $100,000 threshold referenced in Section 4(b).

8. Miscellaneous. The respective agreements, representations, warranties, indemnities and other statements of the Company, and the Placement Agents, as set forth in this Agreement or made by or on behalf of them pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Placement Agent or the Company or any of their respective officers, directors or controlling persons referred to in Sections 5 and 6 hereof, and shall survive delivery of and payment for the Shares. In addition, the provisions of Sections 4(b), 5, 6 and 7 shall survive the termination or cancellation of this Agreement.

This Agreement has been and is made for the benefit of the Placement Agents, the Company and their respective successors and assigns, and, to the extent expressed herein, for the benefit of persons controlling any of the Placement Agents, or the Company, and directors and officers of the Company, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term “successors and assigns” shall not include any Investor merely because of such purchase.

All notices and communications hereunder shall be in writing and mailed or delivered or by telephone or telegraph if subsequently confirmed in writing, (a) if to the Placement Agents, c/▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ Incorporated, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, CPA, with a copy to Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇, Esq. and (b) if to the Company, to its agent for service as such agent’s address appears on the cover page of the Registration Statement with a copy to Mintz, Levin, Cohn, Ferris, Glovsky and Popeo P.C., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq.

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

This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

In consideration of the Placement Agents’ agreement to enter into the Placement Agency Agreement and to proceed with the Offering of the Securities, and for other good and valuable consideration, receipt of which is hereby acknowledged, the undersigned hereby agrees for the benefit of the Company, you and the other Placement Agents that, without the prior written consent of ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, Incorporated on behalf of the Placement Agents, the undersigned will not, during the period ending 90 days (the “Lock-Up Period”) after the date of the prospectus supplement relating to the Offering (the “Prospectus”), directly or indirectly (1) offer, pledge, assign, encumber, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock owned either of record or beneficially (as

In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ Incorporated on behalf of the Placement Agents it will not, during the period ending 90 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.
