Dear Sir or Madam:

Aastrom Biosciences, Inc., a Michigan corporation (the “Company”), proposes to issue and sell to certain investors (collectively, the “Investors”) up to an aggregate of 11,842,105 units (the “Units”), each consisting of one share of common stock, no par value per share (the “Common Stock”), and one warrant to purchase 0.5 shares of the Company’s common stock (the “Warrants” and, together with the Common Stock, the “Securities”). The shares of Common Stock and Warrants are immediately separable and will be issued separately to the Investors. The Company hereby confirms its agreement with BMO Capital Markets Corp. (“BMO” or the “Placement Agent”) to act as placement agent in connection with such issuance and sale.

1. Agreement to Act as Placement Agent. On the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions of this Agreement, the Placement Agent agrees to act as the Company’s exclusive placement agent in connection with the sale, on a best efforts basis, by the Company of the Units to the Investors, and the issuance of the Securities to the Investors. The Placement Agent agrees to use its commercially reasonable efforts to solicit offers to purchase the Units from the Company on the terms and subject to the conditions set forth in the Prospectus (as defined below). The Placement Agent has no authority to bind the Company with respect to any prospective offer to purchase the Units. The Placement Agent shall use commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Units has been solicited by either of the Placement Agent and accepted by the Company, but the Placement Agent shall not, except as otherwise provided in this Agreement, have any liability to the Company in the event any such purchase is not consummated for any reason. The Company shall pay to the Placement Agent 6% of the gross

proceeds received by the Company from the sale of the Units on the Closing Date, without taking into account any proceeds from the exercise of the Warrants.

2. Closing. Concurrently with the execution and delivery of this Agreement, the Company, the Placement Agent, and The Bank of New York as escrow agent (the “Escrow Agent”), shall enter into an Escrow Agreement substantially in the form of Exhibit A attached hereto (the “Escrow Agreement”), pursuant to which an escrow account will be established, at the Company’s expense, for the benefit of the Investors (the “Escrow Account”). Prior to the Closing Date (as hereinafter defined), (i) each of the Investors will deposit an amount equal to the price per Unit as shown on the cover page of the Prospectus (as hereinafter defined) multiplied by the number of Units purchased by it in the Escrow Account, and (ii) the Escrow Agent will notify the Company and the Placement Agent in writing whether the Investors have deposited in to the Escrow Account funds in the amount equal to the proceeds of the sale of all of the Units offered hereby (the “Requisite Funds”). At 10:00 a.m., New York City time, on October 16, 2007, or at such other time on such other date as may be agreed upon by the Company and the Placement Agent but in no event prior to the date on which the Escrow Agent shall have received all of the Requisite Funds (such date is hereinafter referred to as the “Closing Date”), the Escrow Agent will release the Requisite Funds from the Escrow Account for collection by the Company and the Placement Agent as provided in the Escrow Agreement and the Company shall deliver the Units to the Investors, which delivery, with respect to the shares of Common Stock, may be made through the facilities of the Depository Trust Company. The closing (the “Closing”) shall take place at the office of Xxxxxx, Xxxxx & Xxxxxxx LLP, 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000. All actions taken at the Closing shall be deemed to have occurred simultaneously.

(i) Each Issuer Free Writing Prospectus (including, without limitation, any road show that is a free writing prospectus under Rule 433), when considered together with the Pricing Disclosure Materials as of the Applicable Time, did 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 were made, not misleading.

(j) Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Act and the Rules and Regulations on the date

of first use, and the Company has complied with any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Rules and Regulations. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Units, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein that has not been superseded or modified. The Company has not made any offer relating to the Units that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Placement Agent. The Company has retained in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Rules and Regulations and will file with the Commission all Issuer Free Writing Prospectuses, if any, in the time and manner required under Rules 163(b)(2) and 433(d) of the Act.

(k) The Company is, and at the Closing Date will be, duly organized, validly existing and in good standing under the laws of the State of Michigan. The Company has, and at the Closing Date will have, full power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and the Prospectus. The Company is, and at the Closing Date will be, duly licensed or qualified to do business and in good standing as a foreign organization in all jurisdictions in which the nature of the activities conducted by it or the character of the assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect or would not reasonably be expected to have a material adverse effect on or affecting the business, prospects, properties, management, consolidated financial position, stockholders’ equity or results of operations of the Company and its Subsidiaries (as defined below) taken as a whole (a “Material Adverse Effect”). Complete and correct copies of the articles or certificate of incorporation and of the bylaws of the Company and all amendments thereto have been delivered to the Placement Agent, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date.

(l) The Company’s only subsidiaries (each a “Subsidiary” and collectively the “Subsidiaries”) are listed on Schedule 1 to this Agreement. Each Subsidiary has been duly organized and is validly existing as a corporation in good standing under the laws of its jurisdiction of formation. Each Subsidiary is duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing which will not have a Material Adverse Effect. All of the shares of issued capital stock of each subsidiary of the Company have been duly authorized and validly issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of any lien, encumbrance, claim, security interest, restriction on transfer, shareholders’ agreement, voting trust or other defect of title whatsoever.

(m) The issued and outstanding shares of capital stock of the Company have been validly issued, are fully paid and nonassessable and, other than as set forth in the Registration Statement, are not subject to any preemptive rights, rights of first refusal or

similar rights. The Company has an authorized, issued and outstanding capitalization as set forth in the Prospectus as of the dates referred to therein. The descriptions of the securities of the Company in the Registration Statement and the Prospectus are, and at the Closing Date will be, complete and accurate in all respects. Except as set forth in the Registration Statement and the Prospectus, or pursuant to the Company’s benefit plans or direct stock purchase plan as described in the Registration Statement and the Prospectus, the Company does not have outstanding any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to issue or sell, any shares of capital stock or other securities.

(n) The Company has full legal right, power and authority to enter into this Agreement, the Escrow Agreement, the Purchase Agreements and the Warrants (together, the “Transaction Documents”) and perform the transactions contemplated hereby and thereby. The Transaction Documents have been authorized and validly executed and delivered by the Company and are legal, valid and binding agreements of the Company enforceable against the Company in accordance with their respective terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability, including the effect of public policy on the enforceability of provisions relating to indemnification or contribution.

(o) The sale of the Units and the issuance of the Securities have been duly authorized by the Company, and the shares of Common Stock, including the shares that will be issued upon exercise of the Warrants, when issued and paid for in accordance with this Agreement, will be duly and validly issued, fully paid and nonassessable and will not be subject to preemptive or similar rights. The holders of the Securities will not be subject to personal liability by reason of being such holders. The Securities, when issued, will conform in all material respects to the description thereof included in the Prospectus. As of the date hereof, the Company has reserved from its duly authorized capital stock, the maximum number of shares of Common Stock issuable pursuant to this Agreement and the Warrants.

(p) The consolidated financial statements and the related notes included in the Registration Statement and the Prospectus present fairly, in all material respects, the financial condition of the Company and its consolidated Subsidiaries as of the dates thereof and the results of operations and cash flows at the dates and for the periods covered thereby in conformity with generally accepted accounting principles (“GAAP”). No other financial statements or schedules of the Company, any Subsidiary or any other entity are required by the Act or the Rules and Regulations to be included in the Registration Statement or the Prospectus. All disclosures contained in the Registration Statement, the Pricing Disclosure Materials and the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the Rules and Regulations) comply with Regulation G of the Exchange Act and Item 10 of Regulation S-K under the Act, to the extent applicable. The Company and the Subsidiaries do not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations or any “variable interest entities” within the meaning of Financial Accounting Standards Board Interpretation No. 46), not disclosed in the Registration Statement, the Pricing Disclosure Materials and the Prospectus

(q) PricewaterhouseCoopers L.L.P. (the “Accountants”), who have reported on such consolidated financial statements and schedules for the years ended June 30, 2005 through June 30, 2007, are registered independent public accountants with respect to the Company as required by the Act and the Rules and Regulations and by the rules of the Public Accounting Oversight Board. The consolidated financial statements of the Company and the related notes and schedules included in the Registration Statement and the Prospectus have been prepared in conformity with the requirements of the Act and the Rules and Regulations and present fairly the information shown therein.

(r) There is and has been no failure on the part of the Company, or to its knowledge after due inquiry, and any of the Company’s directors or officers, in their capacities as such, to comply with any applicable provisions of the Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations promulgated therewith (the “Xxxxxxxx-Xxxxx Act”). Each of the principal executive officer and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company as applicable) has made all certifications required by Sections 302 and 906 of the Xxxxxxxx-Xxxxx Act with respect to all reports, schedules, forms, statements and other documents required to be filed by it with the Commission. For purposes of the preceding sentence, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in the Xxxxxxxx-Xxxxx Act. The Company has taken all necessary actions to ensure that it is in compliance with all provisions of the Xxxxxxxx-Xxxxx Act that are in effect and with which the Company is required to comply.

(s) The Company and its Subsidiaries maintain systems 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 principles and to maintain asset accountability; (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. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and its Subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of the end of the period covered by the Form 10-K for the year ended June 30, 2007 (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the year ended June 30, 2007 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Exchange Act) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal controls.

(t) Except as set forth in or otherwise contemplated by the most recent Preliminary Prospectus, since the date of the most recent consolidated financial statements of the Company included or incorporated by reference in the most recent Preliminary Prospectus and prior to Closing, (i) there has not been and will not have been any change in the capital stock of the Company (except for changes in the number of outstanding shares of Common Stock of the Company due to the issuance of shares upon the exercise of stock options or the issuance of shares pursuant to the Company’s employee stock purchase plan or direct stock purchase plan, in each case pursuant to such Company option or stock purchase plans as in effect on the date hereof) or long-term debt of the Company or any Subsidiary or any dividend or distribution of any kind declared, set aside for payment, paid or made by the Company on any class of capital stock, or any material adverse change, or any development that would reasonably be expected to result in a material adverse change, in or affecting the business, prospects, properties, management, consolidated financial position, stockholders’ equity, or results of operations of the Company and its Subsidiaries taken as a whole (a “Material Adverse Change”) and (ii) neither the Company nor any Subsidiary has sustained any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor disturbance or dispute or any action, order or decree of any court or arbitrator or governmental or regulatory authority, except in each case as otherwise disclosed in the Registration Statement and the Prospectus.

(u) Since the date as of which information is given in the most recent Preliminary Prospectus, neither the Company nor any Subsidiary has entered, or will enter (other than with respect to transactions that are consistent with the Company’s publicly announced strategy and which are consistent with the “Use of Proceeds” disclosure contained in the Prospectus), into any transaction or agreement, not in the ordinary course of business, that is material to the Company and its Subsidiaries taken as a whole or incurred or will incur any liability or obligation, direct or contingent, not in the ordinary course of business, that is material to the Company and its Subsidiaries taken as a whole.

The Company and its Subsidiaries are not in violation of any provision of their respective organizational or governing documents.

(aa) Neither the execution of the Transaction Documents, nor offering or sale of the Units, nor the issuance of the Securities, nor the consummation of any of the transactions contemplated herein, nor the compliance by the Company with the terms and provisions hereof or thereof will conflict with, or will result in a breach of, any of the terms and provisions of, or has constituted or will constitute a default under, or has resulted in or will result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to the terms of any contract or other agreement to which the Company or its Subsidiaries may be bound or to which any of the property or assets of the Company or its Subsidiaries is subject, except such conflicts, breaches or defaults as may have been waived; nor will such action result in any violation of the provisions of the organizational or governing documents of the Company or any Subsidiary, or

reference therein or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by the Placement Agent and (D) any application or other document, or any amendment or supplement thereto, executed by the Company based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Units under the securities or Blue Sky laws thereof or filed with the Commission or any securities association or securities exchange (each, an “Application”), or (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or in any Permitted Issuer Information or any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Units in the public offering to any person and is based solely on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Placement Agent furnished in writing to the Company by the Placement Agent expressly for inclusion in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information or any Application (as set forth in paragraph (D); and provided further, that such indemnity with respect to any Preliminary Prospectus shall not inure to the benefit of the Placement Agent (or any person controlling the Placement Agent) from whom the person asserting any such loss, claim, damage, liability or action purchased Units which are the subject thereof to the extent that any such loss, claim, damage or liability (i) results from the fact that the Placement Agent failed to send or give a copy of the Prospectus (as amended or supplemented) to such person at or prior to the confirmation of the sale of such Units to such person in any case where such delivery is required by the Act and (ii) arises out of or is based upon an untrue statement or omission of a material fact contained in such Preliminary Prospectus that was corrected in the Prospectus (or any amendment or supplement thereto), unless such failure to deliver the Prospectus (as amended or supplemented) was the result of noncompliance by the Company with Section 4(d). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Placement Agent will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the foregoing indemnity from the Company to the Placement Agent, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Placement Agent furnished in writing to the Company by the Placement Agent expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that the Placement Agent might otherwise have. The Company acknowledges that, for all purposes under this Agreement, the last paragraph on the cover page of the Prospectus constitutes the only information relating to the Placement Agent furnished in writing to the Company by the Placement Agent expressly for inclusion in the Registration Statement, any Preliminary Prospectus or the Prospectus. Notwithstanding the provisions of this Section 8(b),

in no event shall any indemnity by either Placement Agent under this Section 8(b) exceed the total compensation received by the Placement Agent in accordance with Section 1.

(c) Any party that proposes to assert the right to be indemnified under this Section 8 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 8 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that a conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party that would prevent the counsel selected by the indemnifying party from representing the indemnified party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (3) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in each of which cases, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. The Company will not, without the prior written consent of the Placement Agent (which consent will not be unreasonably withheld), settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution has been sought hereunder (whether or not the Placement

Agent or any person who controls the Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent will not be unreasonably withheld.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 8 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Placement Agent, the indemnifying party or parties will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted) to which the indemnifying party or parties may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Placement Agent, on the other, from the offering of the Units. The relative benefits received by the Company, on the one hand, and the Placement Agent, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting Company expenses) received by the Company as set forth in the table on the cover page of the Prospectus bear to the fee received by the Placement Agent hereunder as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Placement Agent, on the other, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Placement Agent, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission; provided that the parties hereto agree that the written information furnished to the Company by the Placement Agent for use in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Placement Agent information as defined in Section 8(b). The Company and the Placement Agent agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation 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, liability, expense or damage, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purpose of this Section 8(d), 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 8(d), the Placement Agent shall not be required to contribute any amount in excess of the total compensation received by it in accordance with

Section 1, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 8(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 8(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld). The Placement Agent’s obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

9. Termination.

(a) The obligations of the Placement Agent under this Agreement may be terminated at any time prior to the Closing Date, by notice to the Company from the Placement Agent, in its sole discretion, without liability on the part of the Placement Agent to the Company if, prior to delivery and payment for the Securities, any of the events described in Sections 7(b) have occurred.

(b) If this Agreement shall be terminated pursuant to any of the provisions hereof, or if the sale of the Units provided for herein is not consummated because any condition to the obligations of the Placement Agent set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will reimburse the Placement Agent for all reasonable, documented out-of-pocket expenses incurred in connection herewith.

10. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Units or any other services the Placement Agent may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Placement Agent: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Placement Agent, on the other, exists; (ii) the Placement Agent is not acting as an advisor, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the offering price of the Units, and such relationship between the Company, on the one hand, and the Placement Agent, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Placement Agent may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Placement Agent and its affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Placement Agent with respect to any breach of fiduciary duty in connection with this offering.

The respective agreements, covenants, indemnities and other statements set forth in Sections 6 and 8 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

In addition, the undersigned agrees that, without the prior written consent of the Placement Agent, it will not, during the period beginning on the date hereof and ending on the date which is 90 days after the date of the final prospectus supplement relating to the Offering, 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.
