Item 1.01 Entry into a Material Definitive Agreement

On February 23, 2007, we entered into a Placement Agency Agreement with Piper Jaffray & Co. (“Piper Jaffray”), pursuant to which Piper Jaffray agreed to act as our placement agent for the offering and sale to certain institutional and accredited investors of units, at a price of $5.74 per unit, constituting a total of 3,745,645 shares of common stock and 1,872,823 common stock warrants (the “Offering”).

The warrants have a five-year exercisability period and an exercise price of $6.25 per share.

We expect to conduct the closing of the Offering on February 28, 2007 and to raise approximately $20 million, net of placement agency fees and estimated offering expenses, from the sale of the units. The units will be immediately separable.

Under the Placement Agency Agreement, we agreed to pay Piper Jaffray an aggregate fee equal to 6.5% of the gross proceeds from the Offering, provided, however, that with respect to securities sold in the Offering to certain purchasers identified in the Placement Agency Agreement, the fee to be paid to Piper Jaffray equaled 5.0% of the gross proceeds. We expect the actual total fee payable to Piper Jaffray to be $1,380,280. We 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 February 14, 2007, we granted Piper Jaffray the right of first refusal to act as our exclusive or bookrunning placement agent in connection with any best efforts placement of registered or unregistered securities, subject to certain exceptions.

We also entered into a Financial Services Advisory Agreement with WBB Securities, LLC (“WBB”), in which we agreed to pay WBB a cash fee equal to 1.5% of the gross proceeds of the Offering. We expect this fee to amount to $322,500.

The Offering was made pursuant to our shelf registration statement on Form S-3 (File No. 333-134129) and a related post-effective amendment. The Company will, pursuant to Rule 424(b) under the Securities Act of 1933, file with the Securities and Exchange Commission a prospectus and prospectus supplements relating to the Offering.

Ladies and Gentlemen:

Cytori Therapeutics, Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to certain investors located by you or set forth on Schedule II attached hereto (each an “Investor” and, collectively, the “Investors”), (i) up to 3,745,645 shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”) and (ii) warrants to purchase up to 1,872,823 shares of Common Stock (the “Warrants” and together with the Shares, the “Securities”). The shares of Common Stock issuable upon exercise of the Warrants are hereinafter referred to as the “Warrant Shares”. The Company desires to engage Piper Jaffray & Co. as its exclusive placement agent (the “Placement Agent”) in connection with such issuance and sale. The Securities are more fully described in the Registration Statement (as hereinafter defined).

The Company has prepared and filed in conformity with the requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the published rules and regulations thereunder (the “Rules and Regulations”) adopted by the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-3 (No. 333-134129), relating to the Securities and the offering thereof from time to time in accordance with Rule 415 of the Rules and Regulations, and such amendments thereof as may have been required. The Registration Statement includes a prospectus dated June 5, 2006 (the “Base Prospectus”). The Company has filed the Base Prospectus with the Commission and has filed with, or transmitted for filing to, or shall promptly hereafter file with or transmit for filing to the Commission, a prospectus supplement relating to the Securities in accordance with Rule 424(b) under the Act (the “Final Prospectus Supplement”). The term “Registration Statement” as used in this Agreement means the initial registration statement (including all exhibits, financial schedules and all documents and information deemed to be a part of the Registration Statement (through incorporation by reference or otherwise)), as amended, at the time and on the date it became effective (the “Effective Date”), including the information (if any) contained in the form of final prospectus filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations and deemed to be part thereof at the time of effectiveness pursuant to Rule 430A of the Rules and Regulations. The term “Prospectus” as used in this Agreement means the Base Prospectus together with the Final Prospectus Supplement. Any preliminary prospectus or prospectus subject to completion included in the Registration Statement or filed with the Commission

pursuant to Rule 424 under the Securities Act is hereafter called a “Preliminary Prospectus.” As used herein, the terms “Base Prospectus,” “Prospectus,” “Registration Statement,” “Preliminary Prospectus” and “Final Prospectus Supplement” shall include any documents incorporated by reference therein; and any reference to any amendment or supplement to the Registration Statement or the Prospectus shall be deemed to refer to and include any document filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the date of the Base Prospectus by the Company with the Commission and on or before the last to occur of the Effective Date, the date of the Preliminary Prospectus, or the date of the Prospectus; and any reference herein to the terms “amend,” “amendment,” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act before or after the Effective Date, the date of such Preliminary Prospectus or the date of the Prospectus, as the case may be, which is incorporated by reference into such amendment or supplement, but excluding any documents or information furnished to the Commission under Item 2.02 or Item 7.01 of any Current Report on Form 8-K. If the Company has filed an abbreviated registration statement to register additional Shares and Warrants pursuant to Rule 462(b) under the Rules and Regulations (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall also be deemed to include such Rule 462(b) Registration Statement. The Company hereby confirms that the Placement Agent, in connection with its duties in such capacity, is authorized to distribute or cause to be distributed the Prospectus (as from time to time amended or supplemented if the Company furnishes amendments or supplements thereto to such Placement Agent).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement or the Prospectus shall be deemed to mean and include the filing of any document under the Exchange Act on or before the Closing Date (as defined herein), which is incorporated by reference in the Registration Statement or the Prospectus, as the case may be.

For purposes of this Agreement, all references to the Registration Statement, the Rule 462(b) Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

1. Agreement to Act as Placement Agent; Delivery and Payment. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to the terms and conditions set forth in this Agreement:

(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 Securities 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 all or part of the Securities from the Company upon the terms and conditions set forth in the Prospectus. The Company expressly acknowledges and agrees that 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 Securities or otherwise provide any financing, and the Placement Agent shall have no authority to bind (and agrees not to purport to bind) the Company in respect of the sale of any Securities.

(b) Concurrently with the execution and delivery of this Agreement, the Company, the Placement Agent and JP Morgan Chase, as escrow agent (the “Escrow Agent”), shall enter into an escrow agreement, dated as of the date hereof (the “Escrow Agreement”) pursuant to which an escrow

account will be established, at the Company’s expense, 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 (the “Escrow Account”). Prior to the Closing Date, (i) each such Investor will deposit in the Escrow Account an amount equal to $5.74 per unit (each unit consisting of one Share and 0.5 Warrants) multiplied by the number of units to be purchased by such Investor (the “Purchase Amount”), and (ii) the Escrow Agent will notify the Company and the Placement Agent in writing of the amount of funds deposited in the Escrow Account.

(c) 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 from its sale of the Securities at such Closing (the “Agency Fee”) provided, however, that with respect to Securities sold in the offering to those Investors whose names are set forth on Schedule II attached hereto, the fee to be paid to the Placement Agent shall equal five percent (5.0%) of the gross proceeds received by the Company at Closing from its sale of such Securities to such Investors.

(d) Payment of the purchase price for, and delivery of, the Securities 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., local time, on February 28, 2007 or at such other time and date as the Placement Agent and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act (such date of payment and delivery being herein referred to as the “Closing Date”), and upon satisfaction of the conditions set forth in this Agreement and the Subscription Agreements (as defined below), the Company shall deliver the Securities, which shall be registered in the name or names and shall be in such denominations as the Placement Agent may request at least one business day before the Closing Date, to the Investors, which delivery, with respect to the Shares, may be made through the facilities of the Depository Trust Company, and the Escrow Agent will disburse the aggregate funds in the Escrow Account to the Company reduced by an amount equal to the sum of the aggregate Agency Fee payable to the Placement Agent and the Placement Agent’s bona fide estimate of the amount, if any, of expenses for which the Placement Agent is entitled to reimbursement pursuant hereto, with such amounts being delivered to the Placement Agent, by wire in federal (same day) funds, as provided in the Escrow Agreement. All such actions taken at the Closing shall be deemed to have occurred simultaneously. Each of the Company and the Placement Agent hereby agree to deliver to the Escrow Agent a Closing Notice in the form attached as Exhibit C to the Escrow Agreement at least one day prior to the Closing Date. At least one day prior to the Closing Date, the Placement Agent shall submit to the Company its bona fide estimate of the amount, if any, of expenses for which such Placement Agent is entitled to reimbursement pursuant hereto. If the Company shall default in its obligations to deliver Securities 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) The sale of the Securities shall be made pursuant to subscription agreements in the form included as Exhibit A hereto (the “Subscription Agreements”). The Company shall have the sole right to accept offers to purchase the Securities 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.

(f) Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date, the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Securities 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.

(g) Any Investor not settling its purchase of Securities pursuant to Section 1(b) 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 Securities to be wired from such accounts to an account designated by the Company in exchange for the release of such Investor’s Securities.

supplement, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations 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 any Preliminary Prospectus, 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, which information the parties hereto agree is limited to the Placement Agent Information and shall 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. 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(c).

(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 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 one or more legal 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other from the offering of the Securities 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 Securities (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 Securities. 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, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by the Placement Agent for use in any Preliminary Prospectus, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Placement Agent Information. 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(c). 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, agreements, 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 Securities. 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 Securities, 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 eighth paragraph and (b) the eleventh 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 Securities (A) trading in securities generally shall have been suspended on or by the New York Stock Exchange, the American Stock Exchange, the Nasdaq Global Market or in the over-the-counter 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 or a material disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States, (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 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 Securities 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 or incorporated by reference therein, there has been any Material Adverse Effect or the Company shall have sustained a loss or interference with its business by strike, fire, flood, earthquake, accident or other calamity, whether or not covered by insurance, 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 Securities 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 Subscription Agreement, 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.

Ladies and Gentlemen:

The undersigned understands that you, as Placement Agent, propose to enter into the Placement Agency Agreement (the “Placement Agreement”) with Cytori Therapeutics, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) of shares (the “Shares”) of common stock, par value $0.001 per share (the “Common Stock”), of the Company. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Placement Agreement.

In consideration of the foregoing, and in order to induce you to participate in the Offering, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without your prior written consent (which consent may be withheld in your sole discretion), the undersigned will not, during the period (the “Lock-Up Period”) beginning on the date hereof and ending on the date 90 days after the date of the final prospectus (including the final prospectus supplement) to be used in confirming the sale of the Shares, (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission in respect of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, (3) 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, or (4) publicly announce an intention to effect any transaction specific in clause (1), (2) or (3) above.

Notwithstanding the foregoing, the restrictions set forth in clause (1) and (2) above shall not apply to (a) transfers (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) with your prior written consent or (iv) effected pursuant to any exchange of “underwater” options with the Company, (b) the acquisition or exercise of any stock option issued pursuant to the Company’s existing stock option plan, including any exercise effected by the

delivery of Shares of the Company held by the undersigned, or (c) the purchase or sale of the Company’s securities pursuant to a plan, contract or instruction that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) that was in effect prior to the date hereof. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. None of the restrictions set forth in this Lock-Up Agreement shall apply to Common Stock acquired in open market transactions.

For the purpose of allowing you to comply with NASD Rule 2711(f)(4), if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or publicly announces other material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16 day period beginning on the last day of the Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18 day period beginning on the date of release of the earnings results or the public announcement regarding the material news or the occurrence of the material event, as applicable, unless you waive, in writing, such extension. The undersigned hereby acknowledges that the Company has agreed not to accelerate the vesting of any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period. In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a sale or disposition of the Common Stock even if such Common Stock would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put option or put equivalent position or call option or call equivalent position) with respect to any of the Common Stock or with respect to any security that includes, relates to, or derives any significant part of its value from such Common Stock.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that, if the Placement Agreement does not become effective, or if the Placement Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder, the undersigned shall be released from all obligations under this Lock-Up Agreement.

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Attn:

Gentlemen:

The purpose of this letter (the “Agreement”) is to set forth the terms of the engagement by Cytori Therapeutics, Inc, a Delaware corporation (“CYTORI” or the “Company”) of WBB Securities, LLC (“WBB”) to serve as the Company’s non-exclusive financial advisor in connection with the engagement of Piper Jaffray Companies, a Delaware company (“PIPER”). WBB will assist CYTORI with the subject matter in the letter agreement dated February 14, 20007 between PIPER and the CYTORI.

1) Indemnification of WBB Securities, LLC.

The Company agrees that it will indemnify and hold harmless WBB and its affiliates and their respective directors, officers, agents and employees and each other person controlling WBB or any of WBB’s affiliates (collectively, the “Indemnified Parties”), to the full extent lawful, from and against any losses, expenses, claims or proceedings (collectively, “losses”) (i) related to or arising out of (A) information provided by the Company, its employees or other agents, which information either the Company or WBB provided to any actual or potential buyers, sellers, investors or offerees, or (B) any other action or failure to act by the Company, its directors, officers, agents or employees or by WBB or any Indemnified Party at the Company’s request or with the Company’s consent, or (ii) otherwise related to or arising out of the engagement or any transaction or conduct in connection therewith and resulting primarily from the Company’s negligence, bad faith or willful misconduct, except that these clauses (i) and (ii) shall not apply with respect to (x) any losses that are finally judicially determined to have resulted primarily from the gross negligence or willful misconduct of such Indemnified Party, or (y) any amount paid in settlement of claims without the Company’s consent, which consent will not be unreasonably withheld.

In the event that the foregoing indemnity is unavailable to any Indemnified Party for any reason (other than as a consequence of a final judicial determination of willful misconduct, bad faith or gross negligence of such Indemnified Party), then the Company agrees to contribute to any losses related to or arising out of the engagement or any transaction or conduct in connection therewith as follows. With respect to such losses referred to in clause (i) of the preceding paragraph, each of the Company and WBB shall contribute in such proportion as is appropriate to reflect the relative benefits received (or anticipated to be received) by WBB, on the one hand, and by the Company and its security holders, on the other hand, from the actual or proposed transaction arising in connection with the engagement. With respect to any other losses (other than as a consequence of a final judicial determination of willful misconduct, bad faith or gross negligence of such Indemnified Party), and for losses referred to in clause (i) of the preceding paragraph if the allocation provided by the immediately preceding sentence is unavailable for any reason, each of the Company and WBB shall contribute in such proportion as is appropriate to reflect not only the relative benefits as set forth above, but also the relative fault of each of the Company and WBB in connection with the statements, omissions or other relevant equitable considerations. Benefits received (or anticipated to be received) by the Company and its security holders shall be deemed to be equal to the aggregate cash consideration and value of securities or any other property payable, issue able, exchangeable or transferable in such transaction or proposed transaction, and benefits received by WBB shall be deemed to be equal to the compensation paid by the Company to WBB (whether in cash or otherwise) in connection with the engagement (exclusive of amounts paid for reimbursement of expenses or paid under this agreement). Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any other alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents), on the one hand, or by WBB, on the other hand. WBB and the Company agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above.

Promptly after WBB receives notice of the commencement of any action or other proceeding in respect of which indemnification or reimbursement may be sought hereunder, WBB will notify the Company thereof; but the omission so to notify the Company shall not relieve the Company from any obligation hereunder unless, and only to the extent that, such omission results in its forfeiture of substantive rights or defenses. If any such action or other proceeding shall be brought against any Indemnified Party, the Company shall, upon written notice given reasonably promptly following WBB’s notice to the Company of such action or proceeding, be entitled to assume the defense thereof at its expense with counsel chosen by the Company and reasonably satisfactory to the Indemnified Parties; provided, however, that any Indemnified Party may at its own expense retain separate counsel to participate in such

defense. Notwithstanding the foregoing, such Indemnified Party shall have the right to employ separate counsel at the Company’s expense and to control its own defense of such action or proceeding if, in the reasonable opinion of counsel to such Indemnified Party, a conflict or likely conflict exists between the Company and such Indemnified Party that would make such separate representation advisable; provided, however, that in no event shall the Company be required to pay fees and expenses under this indemnity for more than one counsel in any one legal action or group of related legal actions. The Company agrees that it will not, without the prior written consent of WBB, which consent shall not be unreasonably withheld or delayed, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters that are the subject of WBB’s engagement (whether or not any Indemnified Party is a party thereto) unless such settlement, compromise or consent includes an unconditional release of WBB and each other Indemnified Party from all liability arising or that may arise out of such claim, action or proceeding.

The Company further agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or any of its affiliates, creditors or security holders for or in connection with the engagement or any actual or proposed transactions or other conduct in connection therewith except for losses incurred by the Company that are finally judicially determined to have resulted primarily from the gross negligence or willful misconduct of such Indemnified Party or have resulted from a breach of the engagement between the Company and WBB.

The foregoing agreement is in addition to any rights WBB may have at common law or otherwise and shall be binding on and inure to the benefit of any successors, assigns, and personal representatives of the Company and each Indemnified Party. This agreement is governed by the laws of the State of California, without regard to such state’s rules concerning conflicts of laws. Each of the parties hereto also hereby submits to the jurisdiction of the state and federal courts located in San Diego County, California in any proceeding arising out of or relating to this agreement, agrees not to commence any suit, action or proceeding relating hereto except in such courts, and waives, to the fullest extent permitted by law, the right to move to dismiss or transfer any action brought in such court on the basis of any objection to personal jurisdiction, venue or inconvenient forum. Solely for purposes of enforcing this agreement, each party hereby consents to personal jurisdiction, service of process and venue in any court in which any claim or proceeding that is subject to this agreement is brought against the other party. Any right to trial by jury with respect to any claim or proceeding related to or arising out of the engagement, or any transaction or conduct in connection therewith or this agreement is waived.

2) Services Provided by WBB Securities, LLC.

(a) Familiarize itself to the extent it deems appropriate and feasible with the business, operations, properties, financial condition, management, and strategic direction of

CYTORI, as well as make any suggestions on how the Company might enhance any of the above;

(b) Evaluate the possible sale of equity related securities in the Company, including, without limitation, evaluating potential capital raising transactions by the Company in the form of a private placement of common stock, convertible preferred stock, other equity securities and/or convertible debt securities; it being agreed and understood that the undertaking of any such possible sale of securities shall be pursuant to a separate agreement between the Parties and CYTORI shall be under no obligation or commitment to undertake such possible sale or placement, respectively, of securities prior to the execution of such separate agreement; and

(c) To the extent requested by the Company, evaluate potential acquisitions, mergers, or joint ventures by the Company, or other strategic alternatives available to the Company.

3) Term of Engagement.

The term of WBB’s engagement shall be for the period commencing on the date of this Agreement and continuing for 30 days of the date of this Agreement (the “Initial Term”), and may be extended beyond the Initial Term by mutual written consent of the Parties. Notwithstanding the foregoing, either Party may terminate this Agreement at any time upon ten (10) days written notice to the other Party, in which event neither Party will have any further obligations hereunder, except for any unpaid amounts under Sections 4 below, which shall survive any such termination.

4) Compensation.

For providing services hereunder, the Company agrees to pay WBB 1.5% of the Gross proceeds raised by the company during the Initial Term or any agreed renewal Terms on the settlement date of the transaction covered by the terms of the Piper letter Agreement.

5) Information.

The Company agrees to make available to WBB all information relating to the Company (the “Information”) as may be reasonably requested by WBB, which Information, taken as a whole, will not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading. The Company agrees to advise WBB immediately of the occurrence of any event or any other change known to the Company that results in the Information, taken as a whole, containing an untrue statement of a material fact or omitting to state any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made,

not misleading. The Company acknowledges that WBB may rely on the Information without undertaking independent verification. WBB hereby agrees and covenants that all non-public Information received by WBB during the term of this Agreement shall be held in strict confidence and not used (except for the purpose of performing WBB’s services under this Agreement), disseminated, released or otherwise disclosed, except as required pursuant to applicable law, rule or regulations, without the prior written consent of the Company.

6) General.

This Agreement represents the entire agreement of the Parties concerning the subject matter hereof and supersedes all prior agreements or understandings, oral or written, between the Parties with respect to the subject matter hereof. This Agreement may not be amended or modified except in writing and signed by WBB and the Company, and shall be governed by and construed in accordance with the laws of the State of California. This Agreement is binding upon and inures to the benefit of the parties hereto. This Agreement may not be assigned by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld.

Delivered herewith are two identical copies of this Agreement. If the foregoing is in accordance with your understanding of the terms of our engagement, please confirm your agreement by signing both enclosed copies of this Agreement and returning to WBB one executed copy of this Agreement.

		Very truly yours,

		WBB Securities, LLC.

Exhibit 10.3

SUBSCRIPTION AGREEMENT

Cytori Therapeutics, Inc.

3020 Callan Road

San Diego, California 92121

Ladies and Gentlemen:

The undersigned (the “Investor”) hereby confirms and agrees with you as follows:

1. This Subscription Agreement (this “Agreement”) is made as of the date set forth below between Cytori Therapeutics, Inc., a Delaware corporation (the “Company”), and the Investor.

2. The Company has authorized the sale and issuance of (i) up to 3,745,645 shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”), and (ii) warrants to purchase up to 1,872,823 shares of Common Stock (the “Warrants” and together with the Shares, the “Securities”) for a purchase price of $5.74 per unit, with each unit consisting of one Share and 0.5 Warrants (the “Offering”). The Offering and issuance of the Securities have been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the Company’s Registration Statement on Form S-3 (No. 333-134129), 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”). The Investor acknowledges that the Company intends to enter into subscription agreements in substantially the same form as this Agreement with certain other investors.

3. As of the Closing (as defined below) and subject to the terms and conditions hereof, the Company and the Investor agree that the Investor will purchase from the Company and the Company will issue and sell to the Investor such number of Shares and Warrants as is set forth on the signature page hereto (the “Signature Page”). The Investor acknowledges that the Offering is not a firm commitment underwriting and that there is no minimum offering amount. Certificates representing the Shares purchased by the Investor will not be issued to the Investor; instead, such Shares will be credited to the Investor using customary procedures for book-entry transfer through the facilities of The Depository Trust Company (“DTC”). The Warrants will be issued by the Company, and delivered to the Investor, in physical form. This Offering will not clear directly through the Placement Agent (as defined below) acting in such capacity. Consequently, the Investor must instruct their individual broker how to settle the transaction.

4. The completion of the purchase and sale of the Securities 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 February 28, 2007. 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, (b) the Company shall deliver to the Investor the Warrants being purchased by the Investor and (c) the aggregate purchase price for the Securities 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 Deposit/Withdrawal At Custodian (“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.

5. The Company has filed with the Securities and Exchange Commission (the “Commission”) a prospectus (the “Base Prospectus”) and will promptly file a final prospectus supplement (collectively with the Base Prospectus, the “Prospectus”) with respect to the Registration Statement in conformity with the Securities Act,

including Rule 424(b) thereunder. The Investor hereby consents to the receipt of the Company’s Prospectus in portable document format, or .pdf, via e-mail.

6. The Company has entered into a Placement Agency Agreement (the “Placement Agreement”), dated February 23, 2007 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 Securities. 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, which shall be a third party beneficiary thereof. Capitalized terms used, but not otherwise defined, herein shall have the meanings ascribed to such terms in the Placement Agreement.

7. The obligations of the Company and the Investor to complete the transactions contemplated by this Agreement shall be subject to the following:

(a) The Company’s obligation to issue and sell the Securities to the Investor shall be subject to: (i) the receipt by the Company of the purchase price for the Shares and Warrants being purchased hereunder as set forth on the Signature Page and (ii) the accuracy of the representations and warranties made by the Investor and the fulfillment of those undertakings of the Investor to be fulfilled prior to the Closing Date.

(b) The Investor’s obligation to purchase the Securities will be subject to the condition that the Placement Agent shall not have: (i) terminated the Placement Agreement pursuant to the terms thereof or (ii) determined that the conditions to closing in the Placement Agreement have not been satisfied.

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 Agreement and otherwise to carry out its obligations hereunder. The execution and delivery of this Agreement 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 Agreement 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.

(b) The Company shall (i) before the opening of trading on The Nasdaq Global Market on the next trading day after the date hereof, issue a press release, disclosing all material aspects of the transactions contemplated hereby and (ii) make such other filings and notices in the manner and time required by the Commission with respect to the transactions contemplated hereby.

(d) The making, execution and performance of this Agreement by the Investor and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under, (i) the charter, bylaws or other organizational documents of such Investor, as applicable, or (ii) any law, order, rule, regulation, writ, injunction, judgment or decree of any court, administrative agency, regulatory body, government or governmental agency or body, domestic or foreign, having jurisdiction over such Investor or its properties, except for any conflict, breach, violation or default which is not reasonably likely to have a material adverse effect on such Investor’s performance of its obligations hereunder or the consummation of the transactions contemplated hereby.

(f) 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 Agreement. “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 Agreement are publicly disclosed.

12. The headings of the various sections of this Agreement have been inserted for convenience of reference only and shall not be deemed to be part of this Agreement.

15. This Agreement may be executed in 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 counterparts have been signed by each party hereto and delivered to the other party.

16. The Investor acknowledges and agrees that such Investor’s receipt of the Company’s counterpart to this Agreement shall constitute written confirmation of the Company’s sale of Securities to such Investor.

CYTORI THERAPEUTICS, INC.

WARRANT


Warrant No.		Original Issue Date: February , 2007

Cytori Therapeutics, Inc., a Delaware corporation (the “Company”), hereby certifies that, for value received, or its permitted registered assigns (the “Holder”), is entitled to purchase from the Company up to a total of shares of common stock, $0.001 par value per share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price equal to $6.25 per share (as adjusted from time to time as provided herein, the “Exercise Price”), at any time and from time to time on or after the date hereof (the “Original Exercisability Date”) and through and including February , 2012 (the “Expiration Date”), and subject to the following terms and conditions:

This Warrant is being issued pursuant to that certain Subscription Agreement, dated February 23, 2007, by and between the Company and the purchaser identified therein (the “Purchase Agreement”). The original issuance of the Warrant by the Company pursuant to the Purchase Agreement has been registered pursuant to a Registration Statement on Form S-3 (File No. 333-134129) (the “Registration Statement”).

1. Definitions. In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement.

2. List of Warrant Holders. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder (which shall include the initial Holder or, as the case may be, any registered assignee to which this Warrant is permissibly assigned hereunder from time to time). The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

3. List of Transfers; Restrictions on Transfer. The Company shall register any such transfer of all or any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at its address specified herein. Upon any such registration or transfer, a new Warrant to purchase Common Stock, in substantially the form of this Warrant (any such new Warrant, a “New Warrant”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the

transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations in respect of the New Warrant that the Holder has in respect of this Warrant.

4. Exercise and Duration of Warrant.

(a) All or any part of this Warrant shall be exercisable by the registered Holder in any manner permitted by Section 10 of this Warrant at any time and from time to time on or after the Original Exercisability Date and through and including the Expiration Date. Subject to Section 11 hereof, at 5:00 p.m., New York City time, on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value and this Warrant shall be terminated and no longer outstanding.

(b) The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached hereto (the “Exercise Notice”), completed and duly signed, and (ii) if such Holder is not utilizing the cashless exercise provisions set forth in this Warrant, payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised. The date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise Date.” The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder, but if it is not so delivered then such exercise shall constitute an agreement by the Holder to deliver the original Warrant to the Company as soon as practicable thereafter. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

5. Delivery of Warrant Shares.

(a) Upon exercise of this Warrant, the Company shall promptly (but in no event later than three Trading Days after the Exercise Date) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the Warrant Shares issuable upon such exercise, free of restrictive legends. The Holder, or any Person permissibly so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of the Exercise Date. The Company shall, upon the written request of the Holder, use its best efforts to deliver, or cause to be delivered, Warrant Shares hereunder electronically through the Depository Trust and Clearing Corporation or another established clearing corporation performing similar functions, if available; provided, that, the Company may, but will not be required to, change its transfer agent if its current transfer agent cannot deliver Warrant Shares electronically through the Depository Trust and Clearing Corporation. If as of the time of exercise the Warrant Shares constitute restricted or control securities, the Holder, by exercising, agrees not to resell them except in compliance with all applicable securities laws.

(b) If by the close of the third Trading Day after delivery of an Exercise Notice and the payment of the aggregate exercise price in any manner permitted by Section 10 of this Warrant, the Company fails to deliver to the Holder a certificate representing the required number of Warrant Shares in the manner required pursuant to Section 5(a), and if after such third Trading Day and prior to the receipt of such Warrant Shares, the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall, within three Trading Days after the Holder’s request and in the Holder’s sole discretion, either (i) pay in cash to the Holder an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Warrant Shares, times (B) the closing bid price on the date of the event giving rise to the Company’s obligation to deliver such certificate.

(c) To the extent permitted by law, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

6. Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or the Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for

and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

8. Reservation of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares that are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.

9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9.

(a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(b) Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, distributes to all holders of Common Stock for no consideration (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset besides cash (in each case, “Distributed Property”), then, upon any exercise of this Warrant that occurs after the record date fixed for determination of stockholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable upon such

exercise (if applicable), the Distributed Property that such Holder would have been entitled to receive in respect of such number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date.

(c) Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects (A) any merger of the Company with (but not into) another Person, in which the shareholders of the Company immediately prior to the transaction own less than a majority of the outstanding stock of the surviving entity, or (B) any merger or consolidation of the Company into another Person, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer approved or authorized by the Company’s Board of Directors is completed pursuant to which holders of at least a majority of the outstanding Common Stock tender or exchange their shares for other securities, cash or property, or (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (each, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate Consideration”), and the Holder shall no longer have the right to receive Warrant Shares upon exercise of this Warrant. The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Warrant. The provisions of this paragraph (c) shall similarly apply to subsequent transactions of a Fundamental Transaction type. Notwithstanding the foregoing, in the event of a Fundamental Transaction in which the consideration consists of substantially all cash or securities of a private company, at the request of the Holder delivered before the 20th day after such Fundamental Transaction, the Company (or the successor entity) shall purchase this Warrant from the Holder by paying to the Holder, within five Business Days after such request (or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date of such Fundamental Transaction. For purposes hereof, “Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg Financial Markets (“Bloomberg”) determined as of the day immediately following the public announcement of the applicable Fundamental Transaction and reflecting (i) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of such date of request and (ii) an expected volatility equal to the greater of 50% and the 100 day volatility obtained from the HVT function on Bloomberg.

(d) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section 9, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

(e) [Reserved.]

(f) Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

(g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will, at the written request of the Holder, promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, in good faith, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s Transfer Agent.

(h) Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then, except if such notice and the contents thereof shall be deemed to constitute material non-public information, the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction at least 10 Trading Days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all reasonable steps to give Holder the practical opportunity to exercise this Warrant prior to such time; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

10. Payment of Exercise Price. The Holder may pay the Exercise Price in one of the following manners:

(a) Cash Exercise. If an Exercise Notice is delivered at a time when the Registration Statement is effective, then the Holder shall deliver immediately available funds; or

(b) Cashless Exercise. If an Exercise Notice is delivered at a time when the Registration Statement is not then effective, then the Holder shall notify the Company in an Exercise Notice of its election to utilize cashless exercise, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = Y [(A-B)/A]

where:

X = the number of Warrant Shares to be issued to the Holder.

Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

A = the closing price on the Trading Day immediately prior to the Exercise Date.

B = the Exercise Price then in effect.

11. Limitations on Exercise. (a) Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to ensure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by the Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Each delivery of an Exercise Notice by the Holder will constitute a representation by the Holder that it has evaluated the limitation set forth in this Section and determined that issuance of the full number of Warrant Shares requested in such Exercise Notice is permitted under this Section. The Company’s obligation to issue shares of Common Stock in excess of the limitation referred to in this Section shall be suspended (and, except as provided below, shall not terminate or expire notwithstanding any contrary provisions hereof) until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation; provided, that, if, as of 5:00 P.M., New York City time, on the Expiration Date, the Company has not received written notice that the shares of Common Stock may be issued in compliance with such limitation, the Company’s obligation to issue such shares shall terminate. This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount

of securities or other consideration that such Holder may receive in the event of a Fundamental Transaction as contemplated in Section 9 of this Warrant. By written notice to the Company, the Holder may waive the provisions of this Section but any such waiver will not be effective until the 61st day after such notice is delivered to the Company, nor will any such waiver affect any other Holder.

(b) Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to ensure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 9.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Each delivery of an Exercise Notice hereunder will constitute a representation by the Holder that it has evaluated the limitation set forth in this Section and determined that issuance of the full number of Warrant Shares requested in such Exercise Notice is permitted under this Section. The Company’s obligation to issue shares of Common Stock in excess of the limitation referred to in this Section shall be suspended (and, except as provided below, shall not terminate or expire notwithstanding any contrary provisions hereof) until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation; provided, that, if, as of 5:00 P.M., New York City time, on the Expiration Date, the Company has not received written notice that the shares of Common Stock may be issued in compliance with such limitation, the Company’s obligation to issue such shares shall terminate. This provision shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a Fundamental Transaction as contemplated in Section 9 of this Warrant. This restriction may not be waived.

12. No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares that would otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the closing price of one Warrant Share as reported by the applicable Trading Market on the Exercise Date.

13. Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section at or prior to 5:00 p.m. (New York City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section on a day that is not a Trading Day or later than 5:00 p.m. (New York City time) on any Trading Day, (iii) the

Trading Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. The addresses for such notices or communications shall be: if to the Company, to Cytori Therapeutics, Inc., 3020 Callan Road, San Diego, California 92121, Attention: Chief Executive Officer, (Facsimile No.: 858-458-0995) (or such other address as the Company shall indicate in writing in accordance with this Section) or (ii) if to the Holder, to the address or facsimile number appearing on the Warrant Register (or such other address as the Holder shall indicate in writing in accordance with this Section).

14. Warrant Agent. The Company shall serve as warrant agent under this Warrant. Upon 30 days’ notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act.
