On the basis of the representations, warranties and agreements of the Company and its Subsidiary (as defined below) herein contained, and subject to all the terms and conditions of this Agreement: (a) The Company hereby authorizes the Placement Agents to act as its exclusive agents to solicit offers for the purchase of all or part of the Stock from the Company in connection with the proposed offering of the Stock (the "OFFERING"). Until the Closing Date (as defined in Section 3 hereof), the Company shall not, without the prior consent of the Representative, solicit or accept offers to purchase the Stock otherwise than through the Placement Agents.

The Placement Agents shall make commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Stock has been 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 purchase any Stock for its own account and, in soliciting purchases of Stock, the Placement Agents shall act solely as the Company's agent and not as principals. Notwithstanding the foregoing and except as otherwise provided in Section 1(c), 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 Stock as principals. (c) Subject to the provisions of this Section 1, offers for the purchase of Stock may be 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 Stock received by it as agent of the Company. The Company shall have the sole right to accept offers to purchase the Stock 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 Stock received by it, in whole or in part, and any such rejection shall not be deemed a breach of its agreement contained herein. (d) The purchases of the Stock by the Purchasers shall be evidenced by the execution of the Subscription Agreements by each of the parties thereto. (e) As compensation for services rendered, on the Closing Date 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 amount equal to seven percent (7%) of the gross proceeds received by the Company from the sale of the Stock on such Closing Date. (f) No Stock which the Company has agreed to sell pursuant to this Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Stock shall have been delivered to the Purchaser thereof against payment by such Purchaser. If the Company shall default in its obligations to deliver Stock to a Purchaser whose offer it has accepted, the Company shall indemnify and hold the Placement Agents harmless against any loss, claim or damage arising from or as a result of such default by the Company. 2 2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND ITS SUBSIDIARY. The Company and its Subsidiary represent and warrant to, and agrees with, the several Placement Agents and the Purchasers that: (a) The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the "SECURITIES ACT"), and has filed with the Securities and Exchange Commission (the "COMMISSION") a registration statement on such form (Registration File No. 333-125731), which became effective as of June 17, 2005, for the registration under the Securities Act of the Stock. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the "RULES AND REGULATIONS") of the Commission promulgated thereunder, a supplement to the form of prospectus included in such registration statement relating to the placement of the Stock and the plan of distribution thereof and has advised the Representative of all further information (financial and other) with respect to the Company required to be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the "REGISTRATION STATEMENT"; such prospectus in the form in which it appears in the Registration Statement is hereinafter called the "BASE PROSPECTUS"; and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the "PROSPECTUS SUPPLEMENT." Any reference herein to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein, including all exhibits thereto (the "INCORPORATED DOCUMENTS") pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference herein to the terms "amend," "amendment" or "supplement" with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is "contained," "included," "described," "set forth" or "stated" in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company's knowledge, is threatened by the Commission. For purposes of this Agreement, "FREE WRITING PROSPECTUS" has the meaning set forth in Rule 405 under the Securities Act and the "TIME OF SALE PROSPECTUS" means the 3 preliminary prospectus, if any, together with the free writing prospectuses, if any, used in connection with the Offering, including any documents, incorporated by reference therein. (b) The Registration Statement (and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations. Each of the Base Prospectus, the Time of Sale Prospectus, if any, and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus, the Time of Sale Prospectus, if any, or Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading. Notwithstanding the foregoing, the Company makes no representations or warranties as to information, if any, contained in or omitted from the Time of Sale Prospectus, if any, or the Prospectus Supplement or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Placement Agent specifically for use in the Registration Statement, the Time of Sale Prospectus, if any, or the Prospectus Supplement, which information the parties hereto agree is limited to the Placement Agents' Information as defined in Section 16.

Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or behalf of or used by the Company complies or will comply in all material respects with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder.

(f) The Stock to be issued and sold by the Company hereunder and under the Subscription Agreements has been duly and validly authorized and, when issued and delivered against payment therefor as provided herein, will be duly and validly issued, fully paid and nonassessable and free of any preemptive or 5 similar rights.

(k) There is no franchise, contract, lease, instrument or other document of a character required by the Securities Act or the Rules and Regulations to be described in the Base Prospectus or the Prospectus Supplement, or to be filed as an exhibit to the Registration Statement, which is not described or filed as required; and all statements summarizing any such franchises, contracts, leases, instruments or other documents or legal matters contained in the Registration Statement are accurate and complete in all material respects, except as redacted pursuant to confidential treatment requests.

(r) Neither the Company nor its Subsidiary is (i) in violation of any provision of its charter or bylaws, (ii) in default in any respect, and no event has occurred which, with notice or lapse of time or both, would constitute such a default, in the due performance or observance of any term, covenant, or condition of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which it is a party or by which it is bound or to which any of its property or assets is subject, or (iii) in violation in any respect of any statute, law, rule, regulation, ordinance, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or its Subsidiary, or any of their properties, as applicable (including, without limitation, those administered by the Food and Drug Administration of the U.S. Department of Health and Human Services (the "FDA") or by any foreign, federal, state or local governmental or regulatory authority performing functions similar to those performed by the FDA), except, with respect to clauses (ii) and (iii), any violations or defaults which, singularly or in the aggregate, would not have a Material Adverse Effect. (s) The contracts described in the Company's regular reports on Forms 10-Q, 10-K, and 8-K as filed by the Company with the Commission or incorporated by reference therein that are material to the Company are in full force and effect on the date hereof, and neither the Company nor, to the Company's knowledge, any other party to such contracts is in breach of or default under any of such contracts which would have a Material Adverse Effect. (t) No labor problem or dispute with the employees of the Company or its Subsidiary exists or, to the Company's knowledge, is threatened or imminent, which might be expected to have a Material Adverse Effect. Neither the Company nor its Subsidiary is aware that any key employee of the Company or its Subsidiary or significant group of employees of the Company or its 9 Subsidiary plans to terminate employment with the Company or its Subsidiary. (u) Each of the Company and its Subsidiary has fulfilled its obligations, if any, under the minimum funding standards of Section 302 of the United States Employee Retirement Income Security Act of 1974 ("ERISA") and the regulations and published interpretations thereunder with respect to each "PLAN" (as defined in Section 3(3) of ERISA and such regulations and published interpretations) in which employees of the Company and its Subsidiary are eligible to participate and each such plan is in compliance in all material respects with the presently applicable provisions of ERISA and such regulations and published interpretations. No "PROHIBITED TRANSACTION" (as defined in Section 406 of ERISA, or Section 4975 of the Internal Revenue Code of 1986, as amended from time to time (the "CODE")) has occurred with respect to any employee benefit plan which could have a Material Adverse Effect. Each of the Company and its Subsidiary has not incurred any unpaid liability to the Pension Benefit Guaranty Corporation (other than for the payment of premiums in the ordinary course) or to any such plan under Title IV of ERISA. Each "PENSION PLAN" (as defined in ERISA) for which the Company or its Subsidiary would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which could cause the loss of such qualification. (v) The Company and its Subsidiary maintain insurance in such amounts and covering such risks as is adequate for the conduct of its business and the value of its properties and as is customary for companies engaged in similar businesses in similar industries; all such insurance is fully in force on the date hereof and will be fully in force on the Closing Date. (w) Each of the Company and its Subsidiary has made all filings, applications and submissions required by, and possesses all approvals, licenses, certificates, certifications, clearances, consents, exemptions, marks, notifications, orders, permits and other authorizations issued by, the appropriate federal, state or foreign regulatory authorities (including, without limitation, the FDA, and any other foreign, federal, state or local government or regulatory authorities performing functions similar to those performed by the FDA) necessary to conduct its business as presently conducted (collectively, "PERMITS"), except for such Permits which the failure to obtain would not have a Material Adverse Effect, and is in compliance with the terms and conditions of all such Permits; all of such Permits held by each of the Company and its Subsidiary are valid and in full force and effect; there is no pending or threatened action, suit, claim or proceeding which may cause any such Permit to be limited, revoked, cancelled, suspended, modified or not renewed and each of the Company and its Subsidiary has not received any notice of proceedings relating to the limitation, revocation, cancellation, suspension, modification or non-renewal of any such Permit which, singularly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect, whether or not arising from 10 transactions in the ordinary course of business, except as set forth in or contemplated by the Base Prospectus. (x) Cacciamatta Accountancy Corp., who have certified certain financial statements of the Company and delivered their report with respect to the audited consolidated financial statements and schedules included in the Base Prospectus, the Prospectus Supplement or the Registration Statement, or incorporated by reference therein, as the case may be, are independent registered public accountants with respect to the Company within the meaning of the Securities Act and the Rules and Regulations. (y) Each of the Company and its Subsidiary has filed all foreign, federal, state and local tax returns that are required to be filed or has requested extensions thereof (except in any case in which the failure so to file would not have a Material Adverse Effect, except as set forth in the Base Prospectus) and has paid all taxes required to be paid by it and any other assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that is currently being contested in good faith or as would not have a Material Adverse Effect, except as set forth in the Base Prospectus. (z) The principal executive officer and principal financial officer of the Company have made all certifications required by the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the "SARBANES-OXLEY ACT"), and the statements contained in any such certification are complete and correct. The Company maintains "disclosure controls and procedures" (as defined in Rule 13a-14(c) under the Exchange Act), and such controls and procedures are designed (i) to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms and (ii) to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. The Company does not have any material weaknesses in internal controls, and to the Company's knowledge there has been no fraud, whether or not material, that involves management or other employees of the Company or its Subsidiary who have a significant role in the Company's internal controls. The Company is otherwise in compliance in all respects with all applicable effective provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated by the Commission (and intends to comply with all applicable provisions that are not yet effective upon effectiveness). (aa) Each of the Company and its Subsidiary maintains a system of internal accounting controls sufficient to provide reasonable assurance 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 generally accepted accounting 11 principles and to maintain accountability of 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 the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Base Prospectus, since the end of the Company's most recent fiscal year, there has been no change in the Company's or its Subsidiary'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. (bb) Each of the Company and its Subsidiary (i) is in compliance in all material respects with any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants ("ENVIRONMENTAL LAWS"), (ii) has received and is in compliance with all permits, licenses or other approvals required of it under applicable Environmental Laws to conduct its business and (iii) has not received notice of any actual or potential liability for the investigation or remediation of any disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals, or liability would not, individually or in the aggregate, have a Material Adverse Effect, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated by the Base Prospectus (exclusive of any supplement thereto). Neither the Company nor its Subsidiary has been named as a "POTENTIALLY RESPONSIBLE PARTY" under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended. (cc) There has been no storage, disposal, generation, manufacture, refinement, transportation, handling or treatment of medical wastes, toxic wastes, hazardous wastes or hazardous substances by the Company or its Subsidiary (or, to the Company's knowledge, any of the Company's or its Subsidiary's predecessors in interest) at, upon or from any of the property now or previously owned or leased by the Company or its Subsidiary in violation of any applicable Environmental Law which would require remedial action under any applicable Environmental Law, except for any violation or remedial action which would not cause, singularly or in the aggregate with all such violations and remedial actions, a Material Adverse Effect; there has been no material spill, discharge, leak, emission, injection, escape, dumping or release of any kind onto such property or of any medical wastes, toxic wastes, hazardous wastes or hazardous substances due to or caused by the Company or its Subsidiary or with respect to which the Company or its Subsidiary had knowledge, except for any such spill, discharge, leak, emission, injection, escapes, dumpings or releases which would not cause or would not be reasonably likely to cause, singularly or in the aggregate with all such spills, discharges, leaks, emissions, injections, escapes, dumpings or releases, a Material Adverse Effect; and the terms "hazardous substances," "toxic wastes," "hazardous wastes" and "medical wastes" shall have the meanings specified in any applicable Environmental Laws. 12 (dd) In the ordinary course of its business, the Company and its Subsidiary periodically reviews the effect of Environmental Laws on the business, operations and properties of each of the Company and its Subsidiary in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties).

INDEMNIFICATION AND CONTRIBUTION. (a) The Company shall indemnify and hold harmless the Placement Agents, their respective officers, employees, representatives and agents and each person, if any, who controls such Placement Agents within the meaning of the Securities Act (collectively the "PLACEMENT AGENT INDEMNIFIED PARTIES" and each a "PLACEMENT AGENT INDEMNIFIED PARTY") against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which that Placement Agent Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Registration Statement, the Time of Sale Prospectus, if any, or the Prospectus Supplement or in any amendment or supplement thereto, (ii) the omission or alleged omission to state in the Base Prospectus, the Registration Statement, the Time of Sale Prospectus, if any, or the Prospectus Supplement or in any amendment or supplement thereto a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) any breach of the representations and warranties of the Company contained herein or (iv) 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 Stock or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i), (ii) or (iii) above; (provided that the Company shall not be liable in the case of any matter covered by this clause (iv) to the extent that 26 it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such act or failure to act undertaken or omitted to be taken by such Placement Agent through its gross negligence or willful misconduct) and shall reimburse each Placement Agent Indemnified Party promptly upon demand for any legal or other expenses reasonably incurred 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 connection with any such loss, claim, damage, liability or action as such 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, liability or action arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from the Base Prospectus, the Registration Statement, the Time of Sale Prospectus, if any, or the Prospectus Supplement or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Placement Agent through the Representative specifically for use therein, which information the parties hereto agree is limited to the Placement Agents' Information (as defined in Section 16). 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 its officers, employees, representatives and agents, each of its directors and each person, if any, who controls the Company within the meaning of the Securities Act (collectively the "COMPANY INDEMNIFIED PARTIES" and each a "COMPANY INDEMNIFIED PARTY") against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company Indemnified Parties may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Registration Statement, the Time of Sale Prospectus, if any, or the Prospectus Supplement or in any amendment or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, 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 or on behalf of that Placement Agent through the Representative specifically for use therein, and shall reimburse the Company Indemnified Parties for any legal or other expenses reasonably incurred by such parties 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 or action as such expenses are incurred; provided that the parties hereto hereby agree that such written information provided by the Placement Agents consist solely of the Placement Agents Information. This indemnity agreement is not exclusive and will be in addition to any liability, which each of the Placement Agents and the Purchasers might otherwise have and shall not limit any rights 27 or remedies which may otherwise be available at law or in equity to the Company Indemnified Parties. Notwithstanding the provisions of this Section 7(b), in no event shall any indemnity by any Placement Agent under this Section 7(b) exceed the total compensation received by such Placement Agent in accordance with Section 1(e). (c) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or 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 7 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or 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 thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof 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 thereof but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized by the indemnifying party in writing, (ii) such indemnified party shall have been advised by such 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 and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action in accordance with the terms hereof and employ counsel reasonably satisfactory to the indemnified party, 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 such action on behalf of such indemnified party, it being understood, 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 fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties, which firm shall be designated in writing by the Representative, if the indemnified parties under this Section 7 consist of any Placement Agent Indemnified Party, or by the Company if the indemnified parties under this Section 7 consist of any Company Indemnified Parties. Each indemnified party, as a condition of the indemnity agreements 28 contained in Sections 7(a) and 7(b) shall use all reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. Subject to the provisions of Section 7(d) below, no indemnifying party shall be liable for any settlement, compromise or consent to the entry of judgment in connection with any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action (other than a judgment entered with the consent of such indemnified party), 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. (d) 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 by this Section 7 effected without its written consent if (i) such settlement is entered into more than 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 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. (e) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (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 from the offering of the Stock or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Placement Agents on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action 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 Stock purchased under this Agreement (before deducting expenses) received by the Company bears to the total compensation received by the Placement Agents with respect to the Stock purchased under this Agreement. The relative fault 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 or omission; provided that the parties hereto agree that the written information furnished to the Company by the Placement 29 Agents for use in the Prospectus Supplement consists solely of the Placement Agents' Information. The Company and the Placement Agents agree that it would not be just and equitable if contributions pursuant to this Section 7(e) were to be determined by pro rata allocation or by any other method of allocation which 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 or liability, or action in respect thereof, referred to above in this Section 7(e) shall be deemed to include, for purposes of this Section 7(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(e), the Placement Agents shall not be required to contribute any amount in excess of the total compensation received by such Placement Agent in accordance with Section 1(e) 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 or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (f) The Placement Agents' obligations to contribute as provided in this Section 7(f) are several in proportion to the total compensation received by each of the Placement Agents in accordance with Section 1(e) and not joint. 8. 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 (including electronic delivery) of and payment for the Stock if, prior to that time, any of the events described in Sections 6(i) or 6(l) have occurred or if the Purchasers shall decline to purchase the Stock for any reason permitted under this Agreement or the Subscription Agreements. 9. REIMBURSEMENT OF PLACEMENT AGENTS' EXPENSES. If the sale of the Stock provided for herein is not consummated because any condition to the obligations of the Placement Agents and the Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 8 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Placement Agents, the Company will reimburse the Placement Agents upon demand for all out-of-pocket expenses (including fees and disbursements of counsel and any expenses advanced by the Placement Agents on the Company's behalf) that shall have been incurred by the Placement Agents in connection with this Agreement and the proposed purchase and sale of the Stock and, upon demand, the Company shall pay the full amount thereof to Representative. 10. SUCCESSORS; PERSONS ENTITLED TO BENEFIT OF AGREEMENT. This Agreement shall inure to the benefit of and be binding upon the Placement Agents, the Purchasers, the Company, and their respective successors. 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 sentence any legal or equitable 30 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 the Placement Agents shall also be for the benefit of the Company Indemnified Parties. 11. ABSENCE OF FIDUCIARY RELATIONSHIP. The Company acknowledges and agrees that: (a) each Placement Agent's 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 sale of the Stock 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 any of the Placements Agents has advised or is advising the Company on other matters; (b) the price of the Stock set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Representative, the Purchasers, 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) the Company has been advised that the Placement Agents 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 Agents have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and (d) the Company 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. 12. SURVIVAL OF INDEMNITIES, REPRESENTATIONS, WARRANTIES, ETC. The respective indemnities, covenants, agreements, representations, warranties and other statements of the Company, its Subsidiary 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 Stock. 31 13.
