Item 1.01               Entry into a Material Definitive Agreement

On August 9, 2006, Cytori Therapeutics, Inc. (the “Company”) entered into a Common Stock Purchase Agreement with Olympus Corporation (the “Purchase Agreement”) and subscription agreements with certain institutional investors (the “Subscription Agreements”), relating to the offering and sale of a total of 2,918,255 shares of common stock at a price of $5.75 per share, which is equal to the August 9, 2006 closing price of the Company’s common stock on the Nasdaq Global Market.

On August 15, 2006, the Company completed the offering of 1,005,212 shares pursuant to the Subscription Agreements (the “Institutional Offering”), raising offering proceeds, net of placement agency fees and estimated offering expenses, of approximately $5.45 million.  The offering made pursuant the Purchase Agreement (the “Olympus Offering”) is expected to close on or before September 8, 2006 and the Company expects the net offering proceeds to be approximately $11,000,000, as no commissions or other fees are payable with respect to the proceeds of the Olympus Offering.

Piper Jaffray & Co. (“Piper Jaffray”) acted as the Company’s placement agent for the Institutional Offering pursuant to a Placement Agency Agreement entered into with the Company on August 9, 2006 (the “Placement Agency Agreement”).  Under the Placement Agency Agreement, the Company agreed to pay Piper Jaffray an aggregate fee equal to 6.5% of the gross proceeds from the Institutional Offering, provided, however, that with respect to 33.33% of the aggregate number of securities sold in the Institutional Offering to certain purchasers identified in the Placement Agency Agreement, the fee to be paid to Piper Jaffray equaled 3.25% of the gross proceeds.  The Company also agreed to pay the fees, disbursements and other charges of counsel to Piper Jaffray, up to $75,000.  Additionally, for a period of one year from June 30, 2006, the Company granted Piper Jaffray the right of first refusal to act as its exclusive placement agent in connection with any best efforts placement of registered or unregistered securities, subject to certain exceptions.

The Institutional Offering and Olympus Offering were made pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-134129).  The Company has, pursuant to Rule 424(b) under the Securities Act of 1933, filed with the Securities and Exchange Commission a prospectus and prospectus supplements relating to these offerings.

Exhibit 10.32

COMMON STOCK PURCHASE AGREEMENT

This Common Stock Purchase Agreement (the “Agreement”) is entered into at 5:00 p.m. California time on August 9, 2006 (the “Effective Date”), by and between Cytori Therapeutics, Inc., a Delaware corporation (the “Company”), and Olympus Corporation, a Japanese corporation (“Purchaser”).

1.             Sale of Stock.  Subject to the terms and conditions of this Agreement, the Company will issue and sell to Purchaser, and Purchaser agrees to purchase from the Company, at a closing to occur at the principal office of the Company within thirty (30) days of the Effective Date (the “Closing”), the number of shares of the Company’s Common Stock (the “Shares”) determined by dividing $11,000,000 (“Purchase Price”) by the closing sale price of the Company’s common stock as quoted on the Nasdaq Stock Market on the Effective Date; provided however, that in the event the total number of shares that would be owned by Olympus, after adding the new Shares as calculated above to the previously acquired 1.1 million shares, would exceed 19.9% of the then total outstanding Cytori shares, the Purchase Price (and the number of new Shares that would be purchased at such price-per-Share) shall be reduced by an amount that would cause the total share ownership of Olympus as calculated above to be  to  exactly 19.9% of the total outstanding Cytori shares.  The Shares shall upon issuance be listed on the Nasdaq Global Market.    The offering and sale of the Shares are being made pursuant to the Registration Statement and the Prospectus (as such terms are defined below). As such, the issuance of the Shares pursuant to this Agreement shall be duly registered under the Securities Act. Purchaser acknowledges that the Company intends to enter into other purchase or subscription agreements on terms substantially similar to the terms of this Agreement with certain other investors and currently intends to offer and sell (the “Offering”) Common Stock, for a total (including Purchaser and such other investors) of up to an aggregate of $                             pursuant to the Registration Statement and Prospectus.

2.             Purchase.  At the Closing, the Company shall deliver to Purchaser the documentation from Company’s transfer agent certifying the completion of the electronic transfer of the Shares into the account specified by Purchaser, and Purchaser shall immediately deliver to the Company the Purchase Price therefor by wire transfer.

3.             Limitations on Transfer.  Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with applicable securities laws and regulations of applicable countries and stock exchanges.

4.             Investment Representations.  In connection with the purchase of the Shares, Purchaser represents to the Company the following:

(a)           Purchaser has received and/or is aware that the Company has filed or shall file with the Securities and Exchange Commission (the “Commission”) a prospectus (the “Base Prospectus”) and a prospectus supplement reflecting the Offering (collectively, the “Prospectus”), with respect to an effective Form S-3 registration statement (File No. 333-134129), (the “Registration Statement”), including any amendments thereto, and the exhibits and

any schedules thereto, the documents otherwise deemed to be a part thereof or included therein by the rules and regulations of the Commission (the “Rules and Regulations”), in conformity with the Securities Act of 1933, as amended (the “Securities Act”), including Rule 424(b) thereunder.  Purchaser hereby confirms that it has had full access to the Base Prospectus and the Company’s periodic reports and other publicly available information incorporated by reference therein, and was able to read, review, download and print such materials. Purchaser further acknowledges that Purchaser and Purchaser’s advisors have had the opportunity to ask questions of and receive answers from the Company’s management concerning this investment.

(b)           Purchaser has not entered into any agreement to pay commissions to any persons with respect to the purchase or sale of the Shares, except commissions for which Purchaser will be responsible.

(c)           Purchaser understands and acknowledges that no Japanese, German or United States federal or state agency, governmental authority, regulatory body, stock exchange or other entity has made any finding or determination as to the merits of this investment, nor have any such agencies, governmental authorities, regulatory bodies, stock exchanges or other entities made any recommendation or endorsement with respect to the Shares.

(d)           Purchaser, in evaluating the merits of an investment in the Shares, is not relying on the Company, its counsel, or any financial or other advisor to the Company for an evaluation of the tax, legal or other consequences of an investment in the Shares.

5.             Legends.  Any physical certificates representing Shares shall bear the following legend:

AND COMPUTERSHARE TRUST COMPANY, INC., A COLORADO CORPORATION, AS RIGHTS AGENT, DATED AS OF MAY 29, 2003 (THE “RIGHTS AGREEMENT”), THE TERMS OF WHICH ARE HEREBY INCORPORATED HEREIN BY REFERENCE AND A COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF CYTORI THERAPEUTICS, INC. UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, SUCH RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND WILL NO LONGER BE EVIDENCED BY THIS CERTIFICATE. CYTORI THERAPEUTICS, INC. WILL MAIL TO THE HOLDER OF THIS CERTIFICATE A COPY OF THE RIGHTS AGREEMENT WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST THEREFOR.

6.             Indemnification.

(a)           Indemnification by the Company. The Company shall indemnify and hold harmless Purchaser, its permitted assignees, officers, directors, agents, brokers, investment advisors and employees, each person who controls Purchaser or a permitted assignee (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers,

2

directors, agents and employees of each such controlling person, and the respective successors, assigns, estate and personal representatives of each of the foregoing, to the fullest extent permitted by applicable law, from and against any and all claims, losses, damages, liabilities, penalties, judgments, costs (including, without limitation, costs of investigation) and expenses (including, without limitation, reasonable attorneys’ fees and expenses) (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus, as supplemented or amended, if applicable, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except (i) to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein, or (ii) as a result of the failure of the Purchaser to deliver a Prospectus, as amended or supplemented, to a purchaser in connection with an offer or sale.  The Company shall notify the Purchaser promptly of the institution, threat or assertion of any proceeding of which the Company is aware in connection with the transactions contemplated by this Agreement.  Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as defined in Section 6(b) hereof) and shall survive the transfer of the Shares by the Purchaser.

(b)           Conduct of Indemnification Proceedings. If any proceeding shall be brought or asserted against any Person entitled to indemnity pursuant to Section 6(a) or 6(b) hereunder (an “Indemnified Party”), such Indemnified Party promptly shall notify the Person from whom indemnity is sought (the “Indemnifying Party) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such proceeding; or (iii) the named parties to any such proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying 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 thereof and such counsel shall be at the expense of the Indemnifying Party).  The Indemnifying Party shall not be

3

liable for any settlement of any such proceeding effected without its written consent, which consent shall not be unreasonably withheld, conditioned or delayed.  No Indemnifying Party shall, without the prior written consent of the Indemnified Party, which consent shall not unreasonably be withheld, conditioned or delayed, effect any settlement of any pending proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding.

All reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within 10 business days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder or pursuant to applicable law).

(c)           The indemnity agreement contained in this Section is in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

7.             Representations by the Company.  In connection with the sale of the Shares by the Company, the Company represents to Purchaser the following:

The Company has timely filed all registration statements, prospectuses, forms, reports and documents required to be filed by it under the Securities Act, or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as the case may be, since December 31, 2002, including the Registration Statement (each a “Company SEC Filing,” and collectively the “Company SEC Filings”).  Each Company SEC Filing (i) as of its date complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and (ii) did not, at the time they were filed, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.  Each of the consolidated financial statements (including, in each case, any notes thereto) contained in the Company SEC Filings was prepared in accordance with generally accepted accounting principles applied (except as may be indicated in the notes thereto and, in the case of unaudited quarterly financial statements, as permitted by Form 10-Q under the Exchange Act) on a consistent basis throughout the periods indicated (except as may be indicated in the notes thereto), and each presented fairly the consolidated financial position of the Company as of the respective date thereof and for the respective periods indicated therein (subject, in the case of unaudited statements, to normal and recurring year-end adjustments.)  The books and records of the Company have been, and are being, maintained in accordance with applicable legal and accounting requirements.  The Company has not, directly or indirectly, disclosed any material non-public information of the Company to Purchaser.  The information concerning the Company set forth in this Agreement, the Prospectus, the Registration Statement, and any document, statement or certificate furnished to Purchaser at the Closing, does not

4

contain any untrue statement of a material fact or omit to state a material fact required to be stated herein or therein or necessary to make the statements and facts contained herein or therein, in light of the circumstances in which they are made, not false and misleading.

8.             Miscellaneous.

(a)           Governing Law.  This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law.

(b)           Entire Agreement; Enforcement of Rights.  This Agreement sets forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them with regard to such subject matter.  No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to this Agreement.  The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party.

(c)           Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith.  In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

(d)           Construction.  This Agreement is the result of negotiations between and has been reviewed by both of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of both of the parties hereto, and no ambiguity shall be construed in favor of or against either one of the parties hereto.

c.             The Investor understands that nothing in this Subscription or any other materials presented to the Investor in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice.  The Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Shares.

d.             Neither the Investor nor any Person acting on behalf of, or pursuant to any understanding with or based upon any information received from, the Investor has, directly or indirectly, engaged in any transactions in the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities) since the earlier to occur of (i) the time that the Investor was first contacted by the Placement Agent or the Company with respect to the transactions contemplated hereby and (ii) the date that is the tenth (10th) trading day prior to the date of this Subscription.  “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not against the box, and all types of direct and indirect stock pledges, forward  sale contracts, options, puts, calls, short sales, swaps, “put equivalent positions” (as defined in Rule 16a-1(h) under the Exchange Act) and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.  The Investor covenants that neither it, nor any Person acting on behalf of, or pursuant to any understanding with or based upon any information received from, the Investor will engage in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions contemplated by this Subscription are publicly disclosed.

(If no exceptions, write “none.” If left blank, response will be deemed to be “none.”)

(a)           The Company hereby engages the Placement Agent to act as its exclusive placement agent in connection with the issuance and sale, by the Company, of Shares to the Investors and the Placement Agent hereby agrees, as an agent of the Company, to use its best efforts to solicit offers to purchase the Shares from the Company upon the terms and conditions set forth in the Prospectus (as hereinafter defined).  Upon the occurrence of the Closing (as hereinafter defined), the Company shall pay to the Placement Agent, by wire transfer of immediately available funds payable to the order of the Placement Agent, to an account designated by the Placement Agent, an aggregate of six and one-half percent (6.5%) of the gross proceeds received by the Company at Closing from its sale of the Shares, provided, however, that with respect to up to 33.33% of the aggregate number of Shares sold in the offering to those Investors whose names are set forth on Schedule III attached hereto, the fee to be paid to the Placement Agent shall equal three and one-quarter percent (3.25%) of the gross proceeds received by the Company at Closing from its sale of such Shares to such Investors.  Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date (as hereinafter defined), the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Shares of the Company (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 Agent in accordance herewith.

(b)           The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a best efforts basis and this Agreement shall not give rise to a commitment by the Placement Agent or any of its affiliates to underwrite or purchase any of the Shares or otherwise provide any financing, and the Placement Agent shall have no authority to (and agrees not to purport to) bind the Company in respect of the sale of any Shares.  The sale of the Shares shall be made pursuant to the subscription terms in the form included as Exhibit A hereto (the “Subscription Terms”).  The Company shall have the sole right to accept offers to purchase the Shares and may reject any such offer in whole or in part, and, except as set forth in Section 4 hereof, in no event shall fees be payable on any proposed purchase which is rejected for any reason or which otherwise does not close for any reason.  Notwithstanding the foregoing, it is understood and agreed that the Placement Agent or any of its affiliates may, solely at their discretion and without any obligation to do so, purchase Shares as principals; provided, however, that any such purchases by the Placement Agent (or its affiliates) shall be fully disclosed to the Company and approved by the Company in accordance with the previous sentence.

(c)           Concurrently with the execution and delivery of this Agreement, the Company, the Placement Agent and Lowenstein Sandler PC, as escrow agent (the “Escrow Agent”), shall enter into an escrow agreement (the “Escrow Agreement”), pursuant to which an escrow account (the “Escrow Account”) will be established for the benefit of the Company and the Investors who desire to settle their purchase through the facilities of The Depository Trust Company’s DWAC system.  Prior to the Closing Date (as hereinafter defined), each such Investor shall deposit into the Escrow Account an amount equal to the product of (x) the number of Shares such Investor has agreed to purchase and (y) the purchase price per share as set forth on the cover page of the Prospectus  (the “Purchase Amount”).  The aggregate of all such Purchase Amounts is herein referred to as the “Escrow Funds.” On the Closing Date, the Escrow Agent will disburse the Escrow Funds from the Escrow Account to the Company and the Placement Agent as provided in the Escrow Agreement, and the Company shall cause its transfer agent to deliver the Shares purchased by such Investors, which delivery may be made through the facilities of The Depository Trust Company’s DWAC system.

(d)           Payment of the purchase price for, and delivery of, the Shares shall be made at a closing (the “Closing”) at the offices of Heller Ehrman LLP, counsel for the Company, located at 4350 La Jolla Village Drive, 7th Floor, San Diego, California, at 10:00 a.m., Pacific Daylight Time, on the third or fourth business day (as permitted under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (collectively with the rules and regulations promulgated thereunder, the “Exchange Act”)) after the determination of the public offering price of the Shares (such date of payment and delivery being herein called the “Closing Date”).  All such actions taken at the Closing shall be deemed to have occurred simultaneously.  No Shares which the Company has agreed to sell pursuant to this Agreement and the Subscription Terms shall be deemed to have been purchased and paid for, or sold by the Company, until such Shares shall have been delivered to the Investor thereof against payment therefor by such Investor.  If the Company shall default in its obligations to deliver Shares to an Investor whose offer it has accepted, the Company shall indemnify and hold the Placement Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company.

(e)           Any Investor not settling its purchase of Shares pursuant to Section 1(c) above shall deposit its respective Purchase Amount into an account or accounts established with the Placement Agent.  On the Closing Date, the Placement Agent shall, with respect to each such Investor, cause the Purchase Amount for such Shares to be wired from such accounts to an account designated by the Company in exchange for the release of such Investor’s Shares.

2.             Representations and Warranties of the Company.  The Company represents and warrants to the Placement Agent and the Investors as follows:

The Company is not aware of any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(h)           Opinion of Counsel to the Company.  The Placement Agent shall have received from Heller Ehrman LLP, counsel to the Company, such counsel’s written opinion, addressed to the Placement Agent and the Investors and dated the Closing Date, in form and substance as is set forth on Exhibit D attached hereto.  Such counsel shall also have furnished to the Placement Agent a written statement, addressed to the Placement Agent and dated the Closing Date, in form and substance as set forth in Exhibit E attached hereto.

(i)            Opinion of Counsel to the Placement Agent.  The Placement Agent shall have received from Lowenstein Sandler PC, such opinion or opinions, dated the Closing Date and addressed to the Placement Agent, covering such matters as are customarily covered in transactions of this type.

(k)           Officer’s Certificate.  The Placement Agent shall have received on the Closing Date a certificate, addressed to the Placement Agent and dated the Closing Date, of the chief executive or chief operating officer and the chief financial officer or chief accounting officer of the Company to the effect that:

(i)            each of the representations, warranties and agreements of the Company in this Agreement were true and correct in all material respects (except for those representations and warranties which are qualified by materiality, in which case such representations and warranties shall be true and correct in all respects) when originally made and are true and correct in all material respects

19

(except for those representations and warranties which are qualified by materiality, in which case such representations and warranties shall be true and correct in all respects) as of the Time of Sale and the Closing Date; and the Company has complied in all material respects with all agreements and satisfied all the conditions on its part required under this Agreement to be performed or satisfied at or prior to the Closing Date;

(ii)           subsequent to the respective dates as of which information is given in the Disclosure Package (taking into account any updates included within the Disclosure Package), there has not been (A) a material adverse change or any development involving a prospective material adverse change in the general affairs, business, prospects, properties, management, financial condition or results of operations of the Company, taken as a whole, (B) any transaction that is material to the Company, taken as a whole, except transactions entered into in the ordinary course of business, (C) any obligation, direct or contingent, that is material to the Company, taken as a whole, incurred by the Company, except obligations incurred in the ordinary course of business, (D) any change in the capital stock (other than a change in the number of outstanding shares of Common Stock due to the issuance of shares upon the exercise of outstanding options or warrants) or any material change in the short term or long term indebtedness of the Company, taken as a whole, (E) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company or (F) any loss or damage (whether or not insured) to the property of the Company which has been sustained or will have been sustained which has had or is reasonably likely to result in a Material Adverse Effect.

(iv)          the signers of said certificate have reviewed the Registration Statement, the Disclosure Package and the Prospectus, and any amendments thereof or supplements thereto (and any documents filed under the Exchange Act and deemed to be incorporated by reference into the Disclosure Package and the Prospectus), and (A) (i) each part of the Registration Statement and any amendment thereof do not and did not contain when the Registration Statement (or such amendment) became effective, any untrue statement of a material fact or omit to state, and did not omit to state when the Registration Statement (or such amendment) became effective, any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) as of the Time of Sale, neither the Disclosure Package nor any individual Issuer Free Writing Prospectus, when considered together with the Disclosure Package, contained any untrue statement of material fact or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and (iii) the Prospectus, as amended or supplemented, does not and did not contain, as of its issue date, any untrue statement of material fact or omit to state and did not omit to state as of such date, a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (B) since the Time of Sale, there has occurred no event required to be set forth in an amendment or supplement to the Registration Statement, the Disclosure Package or the Prospectus which has not been so set forth and there has been no document required to be filed under the Exchange Act that upon such filing would be deemed to be incorporated by reference in to the Disclosure Package and into the Prospectus that has not been so filed.

(l)            Secretary’s Certificate.  On the Closing Date, the Company shall have furnished to the Placement Agent a Secretary’s Certificate of the Company.

(m)          The Nasdaq Global Market.  The Shares shall have been listed and authorized for trading on the Nasdaq Global Market.

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Placement Agent.

6.             Indemnification and Contribution.

(a)           Indemnification of the Placement Agent.  The Company agrees to indemnify, defend and hold harmless the Placement Agent, its directors and officers, and each person, if any, who controls the Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, claim or liability, which, jointly or severally, the Placement Agent or any such person may become subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise, (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, damage, claim or liability (or actions in respect thereof as contemplated below) arises out of or is based upon: (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto (including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, if applicable) or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, the Prospectus (or any amendment or supplement thereto including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus), any Issuer Free Writing Prospectus or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Common Stock (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading; and, in the case of (i) and (ii) above, to reimburse the Placement Agent and each such controlling person for any and all reasonable expenses (including reasonable fees and disbursements of counsel) as such expenses are

21

incurred by the Placement Agent or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action, (iii) any untrue statement or alleged untrue statement made by the Company in Section 3 hereof or the failure by the Company to perform when and as required any agreement or covenant contained herein or (iv) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided to Investors by or with the approval of the Company or based upon written information furnished by or on behalf of the Company including, without limitation, slides, videos, films or tape recordings used in any road show or investor presentations made to investors by the Company (whether in person or electronically) or in connection with the marketing of the Shares; provided, however, that the foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, it arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in or omitted from the Registration Statement, the Disclosure Package, the Prospectus, or any such amendment or supplement, any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with information concerning the Placement Agent furnished in writing by or on behalf of the Placement Agent to the Company expressly for use therein, which information the parties hereto agree is limited to the Placement Agent Information.

(b)           Indemnification of the Company.  The Placement Agent agrees to indemnify, defend and hold harmless the Company, its directors and officers, and any person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, claim, damage, liability or expense, as incurred to which, jointly or severally, the Company or any such person may become subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Placement Agent), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, in the case of each of (i) and (ii) above, to the extent but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Disclosure Package, the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus in reliance upon and in conformity with information concerning the Placement Agent furnished in writing by or on behalf of the Placement Agent to the Company expressly for use therein, and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, that the parties hereto hereby agree that such written information provided by the Placement Agent consists solely of the Placement Agent Information.  Notwithstanding the provisions of this Section 6(b), in no event shall any indemnity by the Placement Agent under this Section 6(b) exceed the total compensation received by such Placement Agent in accordance with Section 1(b).

(c)           Notice and Procedures.  If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company or the Placement Agent (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 6, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the

22

defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise, except to the extent the indemnifying party does not otherwise learn of the Proceeding and such failure results in the forfeiture by the indemnifying party of substantial rights or defenses. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding, (ii) the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties ), in any of which events such reasonable fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). An indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent or if there be a final judgment for the plaintiff, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 6(c), then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d)           Contribution.  If the indemnification provided for in this Section 6 is unavailable to an indemnified party under subsections (a) or (b) of this Section 6 or insufficient to hold an indemnified party harmless in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable indemnifying party shall, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in subsection (a) or (b) above, (i) in such proportion as is 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 Shares 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Placement Agent on the other hand shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the

23

Shares (before deducting expenses) received by the Company and the total placement agent commissions received by the Placement Agent, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Shares.  The relative fault of the Company on the one hand and the Placement Agent on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Placement Agent, on the other hand, and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission.  The Company and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this Section 6(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 6(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this Section 6(d).  Notwithstanding the provisions of this Section 6(d), the Placement Agent shall not be required to contribute any amount in excess of the total commissions received by such Placement Agent in accordance with Section 1(b).  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.

(e)           Representations and Agreements to Survive Delivery.  The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have.  The indemnity and contribution agreements contained in this Section 6 and the covenants, warranties and representations of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Placement Agent, any person who controls the Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or any affiliate of the Placement Agent, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and (iii) the issuance and delivery of the Shares. The Company and the Placement Agent agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection with the issuance and sale of the Shares, or in connection with the Registration Statement, the Disclosure Package or the Prospectus.

7.             Information Furnished by Placement Agent. The Company acknowledges that the statements set forth in (a) the first sentence of the fourth paragraph and (b) the tenth paragraph under the heading “Plan of Distribution” in the Prospectus (the “Placement Agent Information”) constitute the only information relating to the Placement Agent furnished in writing to the Company by the Placement Agent as such information is referred to in Sections 2 and 6 hereof.

8.             Termination.  (a)  The Placement Agent shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the Closing Date, without liability on the part of the Placement Agent to the Company, if (i) prior to delivery and payment for the Shares (A) trading in securities generally shall have been suspended on or by the New York Stock Exchange, the American Stock Exchange or the Nasdaq Global Market, (each, a “Trading Market”), (B) trading in the Common Stock of the Company shall have been suspended on any such exchange, in the over-the-counter market or by the Commission, (C) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities, (D) there shall have occurred any outbreak or material escalation of hostilities or acts of terrorism involving the United States or there shall have been a declaration by the United States of a national emergency or war, (E) there shall have occurred any other calamity or crisis or any material change in general economic, political or financial conditions in the

24

United States or elsewhere, if the effect of any such event specified in clause (D) or (E), in the judgment of the Placement Agent, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Shares on the Closing Date on the terms and in the manner contemplated by this Agreement, the Disclosure Package and the Prospectus, (ii) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Disclosure Package, there has been any Material Adverse Effect or the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character that in the judgment of the Placement Agent would, individually or in the aggregate, result in a Material Adverse Effect and which would, in the judgment of the Placement Agent, make it impracticable or inadvisable to proceed with the offering or the delivery of the Shares on the terms and in the manner contemplated in the Disclosure Package, (iii) the Company shall have failed, refused or been unable to comply with the terms or perform any agreement or obligation of this Agreement or any of the Subscription Terms, other than by reason of a default by the Placement Agent, or (iv) any condition of the Placement Agent’s obligations hereunder is not fulfilled.  Any such termination shall be without liability of any party to any other party except that the provisions of Section 4, Section 6, and Section 11 hereof shall at all times be effective notwithstanding such termination.

The Company further acknowledges that the Placement Agent is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that the Placement Agent act or be responsible as a fiduciary to the Company, its management, stockholders, creditors or any other person in connection with any activity that the Placement Agent may undertake or has undertaken in furtherance of the offering of the Company’s securities, either before or after the date hereof. The Placement Agent hereby expressly disclaims any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Placement Agent agree that they are each responsible for making their own independent judgments with respect to any such transactions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

13.           Headings.  The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

14.           Entire Agreement; Amendments and Waivers.  This Agreement, together with that certain Engagement Letter, dated June 30, 2006, by and between the Company and you, constitutes the entire agreement between the parties hereto pertaining to the subject matter hereof and supersedes all prior and contemporaneous agreements, understandings, negotiations and discussions, whether oral or written, of the parties, and there are no warranties, representations or other agreements among the parties in connection with the subject matter hereof except as set forth specifically herein or contemplated hereby.  No supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the party to be bound thereby.

The Company hereby waives all right to trial by jury in any Proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final and no-longer-appealable judgment in any such Proceeding brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts in the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

17.           Research Analyst Independence.

The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research department may be different from or inconsistent with the views or advice communicated to the Company by such Placement Agent’s investment banking division. The Company acknowledges that the Placement Agent is a full service securities firm and as such from time to time, subject to applicable securities laws, rules and regulations, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company; provided, however, that nothing in this Section 17 shall relieve the Placement Agent of any responsibility or liability that it may otherwise bear in connection with activities in violation of applicable securities laws, rules and regulations.

3.             The completion of the purchase and sale of the Shares shall occur at a closing (the “Closing”) which, in accordance with Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended, is expected to occur on or about August 15, 2006.  At the Closing, (a) the Company shall cause its transfer agent to release to the Investor the number of Shares being purchased by the Investor and (b) the aggregate purchase price for the Shares being purchased by the Investor will be delivered by or on behalf of the Investor to the Company.  If the Investor chooses to settle via DWAC (by checking the appropriate space on the Signature Page hereto), the provisions set forth in Exhibit A hereto shall be incorporated herein by reference as if set forth fully herein.

4.             The offering and sale of the Shares are being made pursuant to the Registration Statement and the Prospectus (as such terms are defined below).  The Investor acknowledges that the Company intends to enter into subscriptions in substantially the same form as this Subscription with certain other investors and intends to offer and sell (the “Offering”) up to an aggregate of 1,005,212 shares of Common Stock pursuant to the Registration Statement and Prospectus.  In addition, the Investor acknowledges that the Company intends to enter into a common stock purchase agreement with Olympus Corporation whereby Olympus Corporation will purchase $11,000,000 of Company Common Stock at a purchase price per share equal to the purchase price per share to be paid by the Investor.

5.             The Company has filed or shall file with the Securities and Exchange Commission (the “Commission”) a prospectus (the “Base Prospectus”) and a final prospectus supplement (collectively, the “Prospectus”) with respect to the registration statement (File No. 333-134129) reflecting the Offering, including all amendments thereto, the exhibits and any schedules thereto, the documents otherwise deemed to be a part thereof or included therein by the rules and regulations of the Commission (the “Rules and Regulations”) and any registration statement relating to the Offering and filed pursuant to Rule 462(b) under the Rules and Regulations (collectively, the “Registration Statement”), in conformity with the Securities Act of 1933, as amended (the “Securities Act”), including Rule 424(b) thereunder.  The Investor hereby confirms that it has had full access to the Base Prospectus and the Company’s

periodic reports and other information incorporated by reference therein, and was able to read, review, download and print such materials.

6.             The Company has entered into a Placement Agency Agreement (the “Placement Agreement”), dated August 9, 2006 with Piper Jaffray & Co. (the “Placement Agent”), which will act as the Company’s placement agent with respect to the Offering and receive a fee in connection with the sale of the Shares.  The Placement Agreement contains certain representations and warranties of the Company.  The Company acknowledges and agrees that the Investor may rely on the representations and warranties made by it to the Placement Agent in Section 2 of the Placement Agreement to the same extent as if such representations and warranties had been incorporated in full herein and made directly to the Investor.  Capitalized terms used, but not otherwise defined, herein shall have the meanings ascribed to such terms in the Placement Agreement.

8.             The Company hereby makes the following representations, warranties and covenants to the Investor:

a.             The Company has the requisite corporate power and authority to enter into and to consummate the transactions contemplated by this Subscription and otherwise to carry out its obligations hereunder.  The execution and delivery of this Subscription by the Company and the consummation by it of the transactions contemplated hereunder have been duly authorized by all necessary action on the part of the Company.  This Subscription has been duly executed by the Company and, when delivered in accordance with the terms hereof, will constitute the valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as may be limited by any bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws affecting the enforcement of creditors’ rights generally or by general principles of equity.

9.             The Investor hereby makes the following representations, warranties and covenants to the Company:

c.             The Investor understands that nothing in this Subscription or any other materials presented to the Investor in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice.  The Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Shares.

d.             Neither the Investor nor any Person acting on behalf of, or pursuant to any understanding with or based upon any information received from, the Investor has, directly or indirectly, engaged in any transactions in the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities) since the earlier to occur of (i) the time that the Investor was first contacted by the Placement Agent or the Company with respect to the transactions contemplated hereby and (ii) the date that is the tenth (10th) trading day prior to the date of this Subscription.  “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not against the box, and all types of direct and indirect stock pledges, forward  sale contracts, options, puts, calls, short sales, swaps, “put equivalent positions” (as defined in Rule 16a-1(h) under the Exchange Act) and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.  The Investor covenants that neither it, nor any Person acting on behalf of, or pursuant to any understanding with or based upon any information received from, the Investor will engage in any transactions in the securities of the Company (including Short Sales) prior to the time that the transactions contemplated by this Subscription are publicly disclosed.

(If no exceptions, write “none.” If left blank, response will be deemed to be “none.”)

10.          Notwithstanding any investigation made by any party to this Subscription, all covenants, agreements, representations and warranties made by the Company and the Investor herein will survive the execution of this Subscription, the delivery to the Investor of the Shares being purchased and the payment therefor.

11.          This Subscription may not be modified or amended except pursuant to an instrument in writing signed by the Company and the Investor.

12.          In case any provision contained in this Subscription should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein will not in any way be affected or impaired thereby.

13.          This Subscription will be governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to the principles of conflicts of law that would require the application of the laws of any other jurisdiction.

14.          This Subscription may be executed in one or more counterparts, each of which will constitute an original, but all of which, when taken together, will constitute but one instrument, and will become effective when one or more counterparts have been signed by each party hereto and delivered to the other parties.

15.          The Investor acknowledges and agrees that such Investor’s receipt of the Company’s counterpart to this Subscription shall constitute written confirmation of the Company’s sale of Shares to such Investor.
