Conversion and Distribution of Securities

Section 3.1 Conversion of Capital Stock. At the First Effective Time, by virtue of the First Merger and without any action on the part of NeoStem, Subco or Amorcyte or their respective stockholders, as the case may be:

(a) Each share of capital stock of Subco issued and outstanding immediately prior to the First Effective Time shall, by virtue of the First Merger, be converted into and become one validly issued, fully paid and nonassessable share of common stock of Amorcyte. Such common stock shall thereafter constitute all of the issued and outstanding equity of Amorcyte, so that NeoStem shall own all of the capital stock interests in, and equity of, Amorcyte. Each share of capital stock of Subco, when converted in accordance with this Section 3.1(a), will no longer be outstanding, will automatically be cancelled and will cease to exist.

(b) Subject to the other provisions of this Article III, all of the shares of Amorcyte Series A Preferred Stock, all of the shares of Amorcyte Common Stock, all of the Amorcyte Options and Amorcyte Warrants, and all Convertible Debt (to the extent such Convertible Debt has not been converted into Series A Preferred Stock) (with such Convertible Debt being treated as if such Convertible Debt was actually converted into Series A Preferred Stock) in each case, issued and outstanding immediately prior to the First Effective Time, shall, by virtue of the First Merger, be cancelled and converted into the right to receive, in the aggregate, the following:

-14-

(i) 6,821,283 shares of Parent Common Stock, adjusted as set forth in Section 3.3, equal to $10 million divided by the Parent Per Share Value (the “Base Stock Consideration”),

(ii) The right to receive 4,092,768 shares of Parent Common Stock (a number, subject to satisfaction of the conditions precedent set forth in Section 3.6, equal to $6 million divided by the Parent Per Share Value) (the “Contingent Shares”, and together with the Base Stock Consideration, the “Stock Consideration”);

(iii) Warrants to purchase 1,881,008 shares of Parent Common Stock over a seven (7) year period (the number of shares shall be fixed so that the fair market valuation of the Warrants using the Black-Scholes option valuation formula shall be $2 million) at an exercise price of the Parent Per Share Value (the “Warrants”); and

(iv) The Earn Out Payments in accordance with Section 3.7.

(c) Transfer of any shares of Parent Common Stock issued upon exercise of the Warrants will be restricted until the date one year after the Closing Date pursuant to the terms of the Warrants. The Warrants otherwise shall be on customary terms and in customary form for Parent common stock purchase warrants as set forth in Exhibit C.

(d) Amorcyte covenants that, prior to the Closing Date, (i) it will cause all Amorcyte Options and Amorcyte Warrants to have been modified in writings executed by each Optionholder and each Warrantholder, as applicable; provided that such modifications shall be reasonably acceptable to Parent, so that, effective upon the First Effective Time, all Amorcyte Options and all Amorcyte Warrants shall, by virtue of the First Merger, be converted into the right to receive their share of any Earn Out Payments that the holders of such Amorcyte Options and Amorcyte Warrants would have received if they had exercised their Amorcyte Options and/or Amorcyte Warrants, as applicable, prior to the Closing Date (after taking into account any exercise price such holders would have had to pay if they had actually exercised their Amorcyte Options or Amorcyte Warrants) and (ii) all payables due to PCT through the Closing Date will be fully paid and satisfied prior to or at Closing.

(e) As of the Second Effective Time all shares of common stock of Amorcyte issued and outstanding following the First Effective Time shall automatically be cancelled and shall cease to exist, and each holder of any such shares of common stock shall cease to have any rights with respect thereto.

(f) At the Second Effective Time, each common unit of Subco II that is issued and outstanding immediately prior to the Second Effective Time will continue to constitute one validly issued common unit of the Surviving Company. Such common unit shall be the only units of the Surviving Company that are issued and outstanding immediately after the Second Effective Time.

-15-

Section 3.2 Payments by the Parent. Upon the terms and subject to the conditions of this Agreement and on the basis of the representations, warranties and agreements contained herein, at the Closing, the Parent shall cause its transfer agent to issue the Base Stock Consideration in the name of the Escrow Agent, as agent for the Amorcyte Stockholders, and to deliver the Base Stock Consideration to the Escrow Agent, to be held and disbursed by the Escrow Agent pursuant to the terms and conditions of an escrow agreement in the form and substance of the escrow agreement annexed hereto as Exhibit B, subject to such modifications thereof as the Escrow Agent shall reasonably request prior to the Closing and as shall be accepted by the Parent and Amorcyte (such acceptance not to be unreasonably denied) (as so modified, the “Escrow Agreement”). The stock certificates representing the shares of Parent Common Stock held in escrow shall bear restrictive legends as set forth in the Escrow Agreement. Parent also shall issue the Warrants in electronic book entry form in the name of the Amorcyte Stockholders. The Escrow Agreement shall prohibit transfers of interests in the Escrow Account or any of the Stock Consideration, directly or indirectly, until released from the Escrow Account. The Contingent Shares shall be issued to the Amorcyte Stockholders if and when the contingencies set forth in Section 3.6 have been satisfied.

Section 3.3 Adjustment to Base Stock Consideration.

(a) At Closing, Amorcyte shall provide the Parent with an estimated list of all of its Liabilities (the “Estimated Liabilities”). The Estimated Liabilities shall reflect, but not be limited to, all payments required to be made by, or obligations of Amorcyte on or as of the Closing Date (including, without limitation, an estimate of the Amorcyte Expenses incurred to date and to be incurred and a good faith reasonable estimate of any contingent Liabilities and excluding any Convertible Debt).

(b) If the Estimated Liabilities are more than $478,000 (the “Target Liabilities”), the Base Stock Consideration payable at Closing will be decreased by two times (2x) the amount by which the Estimated Liabilities are greater than the Target Liabilities. The decrease will reduce the Base Stock Consideration by two dollars for every dollar by which Estimated Liabilities are greater than the Target Liabilities, with each share of Parent Common Stock valued at the Parent Per Share Value. “Adjusted Stock Consideration”, as used in this Section 3.3, shall mean the Base Stock Consideration as decreased (if at all) by this Section 3.3(b).

(c) The Adjusted Stock Consideration shall be further adjusted (upward or downward, as applicable, but never to an amount greater than the number of shares set forth in Section 3.1(b)(i)) as set forth in Section 3.3(e) after the Closing to reflect the difference, if any, between the Adjusted Closing Liabilities determined pursuant to this Section 3.3(c) and the Estimated Liabilities. “Adjusted Closing Liabilities” means all Liabilities of Amorcyte incurred as of the close of business on the Closing Date (including, without limitation, the Amorcyte Expenses and a good faith reasonable estimate of any contingent Liabilities as of the Closing Date which remain contingent at the date of determination and excluding any Convertible Debt). Within ninety (90) calendar days following the Closing Date, the Parent shall deliver to the Amorcyte Representative a statement setting forth the Adjusted Closing Liabilities (the “Adjusted Closing Liabilities Statement”). To the extent the Parent fails to deliver the Adjusted Closing Liabilities Statement to the Amorcyte Representative within such ninety (90) day period, then the Estimated Liabilities shall be final, conclusive and binding upon all parties hereto. Parent covenants to timely pay all Liabilities set forth on the Adjusted Closing Liabilities Statement.

-16-

(d) The Adjusted Closing Liabilities delivered by the Parent to the Amorcyte Representative shall be conclusive and binding upon the parties unless the Amorcyte Representative, within thirty (30) calendar days after receipt by the Amorcyte Representative of the Adjusted Closing Liabilities Statement, notifies the Parent in writing that the Amorcyte Representative disputes any of the amounts set forth therein, specifying the nature of the dispute and the basis therefor. The parties shall in good faith attempt to resolve any dispute, in which event the Adjusted Closing Liabilities Statement, as amended to the extent necessary to reflect the resolution of the dispute, shall be conclusive and binding on the parties. If the parties do not reach agreement in resolving any and all such disputes within twenty (20) calendar days after notice is given by the Amorcyte Representative to the Parent pursuant to the second preceding sentence, the parties shall, within twenty (20) days thereafter, jointly select and engage an independent accounting firm (other than the Parent’s or Amorcyte’s accounting firm) (the “Firm”) to resolve any remaining disputes regarding the Adjusted Closing Liabilities Statement. Promptly, but no later than twenty (20) calendar days after acceptance of its appointment as the Firm, the Firm shall determine (it being understood that in making such determination, the Firm shall be functioning as an expert and not as an arbitrator), based solely on written submissions by the Parent and the Amorcyte Representative, each containing a computation of Adjusted Closing Liabilities (the final submission made by the Parent and the Amorcyte Representative to the Firm being referred to herein as such party’s “Final Submission”), and not by independent review, only those issues in dispute and shall render a written report as to the resolution of the disputes and the resulting computation of the Adjusted Closing Liabilities. Such written report shall be conclusive and binding on the parties. All proceedings conducted by the Firm shall take place in New York, New York. In resolving any disputed item, the Firm (x) shall be bound by the provisions of this Section 3.3(d) and (y) may not assign a value to any Liability greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party. The fees, costs and expenses of the Firm shall be borne solely by the party whose calculation of Adjusted Closing Liabilities, as reflected in such party’s Final Submission, is furthest in amount, whether positive or negative, from the amount of Adjusted Closing Liabilities as determined by the Firm.

(e) Upon final determination of the Adjusted Closing Liabilities as provided in Section 3.3(d), (i) if the Adjusted Closing Liabilities are greater than the Estimated Liabilities, the Adjusted Stock Consideration shall be further decreased by two times (2x) the excess of the Adjusted Closing Liabilities over the Estimated Liabilities (the “Decrease Amount”); and (ii) if the Adjusted Closing Liabilities are less than the Estimated Liabilities, the Adjusted Stock Consideration shall be increased by two times (2x) the excess of the Estimated Liabilities over the Adjusted Closing Liabilities (the “Increase Amount”), provided that, in no event shall the Adjusted Stock Consideration be increased to be an amount that in the aggregate is greater than the number of shares initially reflected as the Base Stock Consideration in Section 3.1(b)(i) (without regard for any adjustments pursuant to this Section 3.3). If the Adjusted Closing Liabilities are greater than the Estimated Liabilities, then the Parent shall direct the Escrow Agent to return to the Parent, within five (5) Business Days of such determination, Shares of Parent Common Stock representing the Decrease Amount with each share of Parent Common Stock valued at the Parent Per Share Value as of the payment date. On the other hand, if the Estimated Liabilities are greater than the Adjusted Closing Liabilities, then the Parent shall deposit with the Escrow Agent, within five (5) Business Days of such determination, shares of Parent Common Stock representing the Increase Amount with each share of Parent Common Stock valued at the Parent Per Share Value as of the payment date; provided that in no event shall the Parent deposit with the Escrow Agent an aggregate amount of Parent Common Stock greater than the number of shares reflected in Section 3.1(b)(i) as the Base Stock Consideration.

-17-

(f) Amorcyte undertakes and covenants to make all payments required in the Ordinary Course of Amorcyte’s Business through the Closing Date. For avoidance of any doubt, the Adjusted Closing Liabilities shall include all Amorcyte Expenses whenever incurred, as well as all Amorcyte accounts payable incurred in the Ordinary Course of Amorcyte’s Business through the Closing Date. To the extent that any such expense or accounts payable are not due as of the Closing Date and are properly reflected on the Adjusted Closing Liabilities Statement and result in an adjustment of the Base Stock Consideration, Parent shall pay such expenses or accounts payable in the ordinary course when due.

Section 3.4 Distributions; Exchange Ratio; Fractional Shares; Adjustments.

(a) Pursuant to the Voting Agreement, dated as of the date hereof, the Lock-Up Stockholders have irrevocably agreed to vote in favor of the First Merger, this Merger Agreement and the Escrow Agreement and agreed to certain transfer restrictions with respect to their shares in Amorcyte prior to the First Effective Time. Amorcyte represents and warrants that the Lock-up Stockholders now own, and will own after completion of any Amorcyte Financing, a sufficient number of shares of the Amorcyte Series A Preferred Stock and Amorcyte Common Stock to assure that all requisite shareholder consents, votes or approvals will be obtained.

(b) Each Amorcyte Securityholder shall receive, for his, her or its Amorcyte Series A Preferred Stock, Amorcyte Common Stock, Amorcyte Options and Amorcyte Warrants, as applicable, an allocable share of the Base Stock Consideration, as adjusted pursuant to this Agreement, the Warrants, the Contingent Shares, if applicable, and the Earn Out Payments, if applicable, in each case, in accordance with (i) the certificate of incorporation of Amorcyte, including the certificate of designations for the Amorcyte Series A Preferred Stock, (ii) the terms of any stockholder agreements, (iii) the terms of the Amorcyte Options and the Amorcyte Warrants, as amended pursuant to this Agreement, and (iv) the Consideration Allocation and Percentage Certification (subsections (i) through (iii), the “Amorcyte Governing Documents”). At the Closing, Amorcyte shall deliver to the Parent and the Escrow Agent a certification signed by the Amorcyte Representative showing: (a) the number of shares of the Base Stock Consideration, the Warrants and the Contingent Shares, if applicable, allocable to each Amorcyte Securityholder and (b) the percentage interest of each Amorcyte Securityholder in the Base Stock Consideration, Warrants, Contingent Shares, if applicable, and Earn Out Payments, if applicable, (the “Consideration Allocation and Percentage Certification”). Annexed hereto as Exhibit E is a form of the chart showing the aggregate allocation of the consideration to be received hereunder allocated among the holders of Amorcyte Series A Preferred Stock, Amorcyte Common Stock, Amorcyte Options and Amorcyte Warrants. Amorcyte shall deliver Exhibit E to Parent within 5 Business Days of the date of execution of this Agreement. Exhibit E is, and the Consideration Allocation and Percentage Certification shall be, consistent with the Amorcyte Governing Documents in all respects and conclusive and binding on the Amorcyte Securityholders. Prior to Closing, Amorcyte shall provide NeoStem with any updates to Exhibit E required as a result of the Amorcyte Financing.

-18-

(c) Within three (3) Business Days after the final determination of the Adjusted Stock Consideration pursuant to Section 3.3, the Amorcyte Representative shall deliver to the Parent and the Escrow Agent an amended Consideration Allocation and Percentage Certification, which will show (a) the number of shares of Adjusted Stock Consideration, (b) the number of Contingent Shares, if issuable, (c) the number of Warrants and (d) the percentage of Earn Out Payments, if earned, to be issued to or paid to, as applicable, each Amorcyte Securityholder again consistent with Exhibit E and the Amorcyte Governing Documents and rounded in each case to the nearest whole shares as provided in Section 3.4(e).

(d) Within three (3) Business Days of the closing of the Amorcyte Financing, if any, the Amorcyte Representative shall deliver to the Parent and the Escrow Agent an amended Consideration Allocation and Percentage Certification, which will show (a) the number of shares of Adjusted Stock Consideration, (b) the number of Contingent Shares, if issuable, (c) the number of Warrants and (d) the percentage of Earn Out Payments, if earned, to be issued to or paid to, as applicable, each Amorcyte Securityholder again consistent with Exhibit E and the Amorcyte Governing Documents and rounded in each case to the nearest whole shares as provided in Section 3.4(e).

(e) No certificates for fractional shares of Parent Common Stock or Warrants to purchase fractional shares of Parent Common Stock shall be issued. In lieu of any fractional shares or Warrants to purchase a fractional share to which the Amorcyte Securityholders would otherwise be entitled as a result of the distributions provided for herein or in the Escrow Agreement based on the Consideration Allocation and Percentage Certification, all stock issuances of Parent Common Stock or Warrant amounts shall be rounded up or down to the nearest whole share, so that no more than the whole number of shares represented by the Adjusted Stock Consideration and the Contingent Shares, if any, and no more than the whole number of shares represented by the Warrants shall ever be issued.

(f) In the event that, subsequent to the date hereof and prior to the First Effective Time, NeoStem shall declare a stock dividend or other distribution payable in shares of Parent Common Stock or securities convertible into shares of Parent Common Stock or effect a stock split, reclassification, combination or other change with respect to shares of Parent Common Stock, the Adjusted Stock Consideration and Warrants shall be proportionately adjusted to reflect such dividend, distribution, stock split, reclassification, combination or other change.

Section 3.5 Delivery of Certificates to Escrow Agent. Promptly following the First Effective Time, NeoStem shall deposit with the Escrow Agent, for distribution in accordance with the Escrow Agreement, certificates representing the Base Stock Consideration (6,821,283 shares of the Parent Common Stock) in the name of the Escrow Agent for eventual distribution to the Amorcyte Stockholders consistent with the Escrow Agreement. So long as any shares of Parent Common Stock are held in escrow, the Escrow Agreement shall provide that the shares of Parent Common Stock be voted on any matter presented to the shareholders of NeoStem by the Amorcyte Representative.

-19-

Section 3.6 Contingent Shares. Contingent Shares (with an aggregate Parent Per Share Value of $6 million) only shall be issued subject to satisfaction of certain conditions as follows: One-third of the Contingent Shares shall be issued upon (i) the completion of Phase 2 clinical trial for AMR-001 and (ii) issuance of a statistically significant analysis demonstrating satisfaction of the primary clinical end points from the Phase 2 clinical trial, which primary clinical endpoints are described in the Phase 2 clinical trial protocol submitted to the FDA on July 5, 2011 (the “Primary Clinical Endpoints”). The Primary Clinical Endpoints may only be changed in a writing consented to by the Parent and the Amorcyte Representative. One-third of the Contingent Shares shall be issued following a Type B End of Phase 2/Pre-Phase 3 meeting with the FDA wherein AMR-001 is acknowledged in writing by the FDA to be ready for Phase 3. The remaining one-third of the Contingent Shares shall be issued upon the Commencement of the pivotal Phase 3 clinical study for AMR-001.

Section 3.7 Earn Out Payments.

(a) Determination of Earn Out Payments. Parent shall also pay an earn out (the “Earn Out Payments”) (to be paid by Parent to the Amorcyte Representative in trust for the benefit of the Amorcyte Securityholders in accordance with the Consideration Allocation and Percentage Certification and consistent with Exhibit E), equal to 10% of the Net Sales of AMR-001, which payment obligation shall begin following the date of first commercial sale of AMR-001 and continue until the latest date that a valid patent claim exists on a country by country basis covering AMR-001, provided that if Parent licenses or otherwise grants an unaffiliated third party the right to commercialize or otherwise exploit AMR-001 or any portion of AMR-001 (an “Out-License Transaction”) (including, without limitation, an Out-License Transaction for all or part of any territory for AMR-001) then the applicable Earn Out Payment shall be equal to 30% of any sublicensing fees, royalties and milestone fees or profit sharing payments (but not payments for development costs) actually received by NeoStem. NeoStem shall be entitled to recover (i) direct out-of-pocket clinical development costs not previously paid or reimbursed and (ii) any costs, expenses, damages, liabilities, settlement amounts (including any royalties paid to third parties) arising out of or related to claims with respect to patent infringement or otherwise challenging Amorcyte’s ownership of, or right to use, the Intellectual Property (the “Infringement Damage Claims”) by reducing any Earn Out Payments due to the Amorcyte Securityholders pursuant to this Section 3.7(a) by 50% until such costs have been recouped in full; provided that there shall be no double counting of Infringement Damage Claims and provided further that in the event Parent or Amorcyte receives any Infringement Damage Claim, it shall notify the Amorcyte Representative of such claim and shall consult with the Amorcyte Representative with reasonable frequency with respect to the defense of, and negotiation of any settlement with respect to, any such Infringement Damage Claim. All of the payments due hereunder shall be paid to the Amorcyte Representative within ninety (90) days following the end of each calendar quarter.

After the Registration Statement is declared effective by the SEC, each of Parent and Amorcyte shall use reasonable efforts to mail as soon as reasonably practicable to the Amorcyte Stockholders the Prospectus/Joint Proxy Statement, which shall include all information required under applicable Law to be furnished to the Amorcyte Stockholders and NeoStem’s stockholders in connection with this Agreement and the transactions contemplated hereby and shall include the recommendation of Amorcyte’s Board of Directors in favor of the transactions contemplated hereby.

(b) Amorcyte will provide Parent with a representation that the information provided by it for inclusion and/or incorporation into the Registration Statement and/or Form 8-K is true and accurate in all material respects and that there is no material fact or matter which has not been disclosed in the disclosure document which renders such information untrue or misleading in any material respect.

Section 6.5 No Solicitation. (a) Commencing on the date of this Agreement and continuing thereafter, unless and until this Agreement is terminated pursuant to Article IX, Amorcyte shall not, nor shall it authorize or permit any of its Affiliates or any Amorcyte Stockholder, officer, director, employee, investment banker, attorney or other adviser or representative of Amorcyte or any of its Affiliates to (i) solicit, initiate, or encourage the submission of, any Amorcyte Acquisition Proposal (as hereinafter defined), (ii) enter into any agreement or understanding with respect to any Amorcyte Acquisition Proposal or (iii) participate in any discussions or negotiations regarding, or furnish to any person any information for the purpose of facilitating the making of, or take any other action to facilitate any inquiries or the making of, any proposal that constitutes, or may reasonably be expected to lead to, any Amorcyte Acquisition Proposal. Without limiting the foregoing, it is understood that any violation, of which Amorcyte or any of its Affiliates had knowledge at the time of such violation, of the restrictions set forth in the immediately preceding sentence by any Amorcyte Stockholder, officer, director, employee, investment banker, attorney or other adviser or representative of Amorcyte or any of its Affiliates, whether or not such Person is purporting to act on behalf of Amorcyte or any of its Affiliates or otherwise, shall be deemed to be a breach of this Section 6.5 by Amorcyte and its Affiliates. Amorcyte shall notify Parent in accordance with the notice provisions of this Agreement in writing and orally within 24 hours after receipt of any Amorcyte Acquisition Proposal or receipt of any inquiries with respect to any Amorcyte Acquisition Proposal, such notice to include the identity of the Person making such proposal, offer, inquiry or contact, and the terms of such Amorcyte Acquisition Proposal. Amorcyte immediately shall cease and cause to be terminated in all respects all existing discussions or negotiations with any parties conducted heretofore with respect to an Amorcyte Acquisition Proposal. Amorcyte shall not release any third party from, or waive any provision of, any confidentiality or standstill agreement to which it is a party. “Amorcyte Acquisition Proposal” means any proposal for a merger or other business combination involving Amorcyte or any of its Affiliates or any proposal or offer to acquire in any manner, directly or indirectly, an equity interest in Amorcyte or any of its Affiliates, any voting securities of Amorcyte or any of its Affiliates or a substantial portion of the assets of Amorcyte or a license to its Intellectual Property.

(b) Amorcyte acknowledges that damages for any breach of the obligations in this Section will be difficult to measure and that Parent has the right to have the provisions of this Agreement, including this Section, specifically enforced pursuant to Section 10.3. If Amorcyte breaches the obligations set forth in this Section 6.5 and such obligations are not specifically enforced pursuant to Section 10.3, then, if Amorcyte consummates a transaction related to or arising out of an Amorcyte Acquisition Proposal, upon the closing of such transaction, Amorcyte shall pay to the Parent an amount equal to $1,500,000.

-54-

(d) The representations, warranties and covenants contained in this Agreement or in any certificate or other writing delivered in connection with this Agreement shall survive for the periods set forth in this Section 8.1 and shall in no event be affected by any investigation, inquiry or examination made for or on behalf of any party, or the knowledge of any party’s representatives or the acceptance by any party of any certificate or opinion hereunder.

Section 8.2 Indemnification.

(a) The Amorcyte Stockholders (to the extent of their collective interest in the Escrow Account) shall jointly and severally indemnify and hold harmless the Parent, Subco, their Affiliates, and their respective officers, directors, employees, agents and representatives, and any Person claiming by or through any of them (the “Parent Indemnified Parties”), against and in respect of any and all claims, costs, expenses, damages, liabilities, losses or deficiencies (including, without limitation, counsel’s fees and other costs and expenses incident to any suit, action or proceeding) (the “Damages”) arising out of, resulting from or incurred in connection with (i) any inaccuracy in any representation or the breach of any warranty made by Amorcyte in this Agreement (ignoring, for purposes of determining the existence of any such misrepresentation or breach or the amount of Damages with respect thereto, any “materiality”, “Material Adverse Effect” or similar qualifier set forth in such representation or warranty), (ii) the breach by Amorcyte of any covenant or agreement to be performed by it hereunder, (iii) any Taxes relating to the Amorcyte Business with respect to any time prior to the Closing Date, (iv) any Indemnified Liabilities (unless such Indemnified Liabilities have been included in the Adjusted Closing Liabilities Statement), (v) except as contemplated by this Agreement, any liability arising from the operation of the Amorcyte Business or services provided by any Person in the Amorcyte Group with respect to any time prior to the Closing Date outside of the Ordinary Course of Amorcyte’s Business, including but not limited to claims with respect to patent infringement or otherwise challenging Amorcyte's ownership of, or right to use, the Intellectual Property, (vi) any claim by any Person relating to any Indebtedness, equity interest, or option, warrant or other right exercisable, convertible or exchangeable into or for any equity interest of Amorcyte, and (vii) any product liability claim by any Person relating to the Amorcyte Business with respect to any time prior to the Closing Date (to the extent not covered by insurance). The Parent Indemnified Parties shall not be entitled to recover Damages from Amorcyte or the Amorcyte Stockholders for any claim for indemnification pursuant to this Section 8.2(a) first made after the expiration of the Survival Period nor from any other source other than the Escrow Account, except for claims in the nature of fraud, willful breach or intentional misconduct or intentional misrepresentation.

-55-

(b) The Parent shall indemnify and hold harmless the Amorcyte Stockholders (the “Amorcyte Indemnified Parties”) against and in respect of any and all Damages arising out of, resulting from or incurred in connection with (i) any inaccuracy in any representation or the breach of any warranty made by the Parent and Subco in this Agreement, or (ii) the breach by the Parent or Subco of any covenant or agreement to be performed by such party hereunder. Amorcyte Indemnified Parties shall not be entitled to recover Damages from the Parent for any claim for indemnification pursuant to this Section 8.2(b) first made after the expiration of the Survival Period except for claims made against Parent or Subco for failure to pay any portion of, or deliver any portion of, the Base Stock Consideration, the Contingent Shares, the Warrants (including the failure to deliver shares of Parent Common Stock upon the exercise of any Warrants) or the Earn Out Payments (collectively, the “Excluded Payments”) owed to the Amorcyte Securityholders.

(c) Any Person providing indemnification pursuant to the provisions of this Section 8.2 is hereinafter referred to as an “Indemnifying Party” and any Person entitled to be indemnified pursuant to the provisions of this Section 8.2 is hereinafter referred to as an “Indemnified Party.”

(d) Notwithstanding anything to the contrary contained in this Agreement, the Parent may not seek indemnification with respect to any claim for Damages until the aggregate amount of all Damages for which the Parent is seeking indemnification under Section 8.2 equals or exceeds $25,000 (the “Threshold”), whereupon the Parent shall be entitled to seek indemnification with respect to all Damages exceeding the Threshold, provided that the Threshold shall not apply to Amorcyte’s failure to pay any Indemnified Liabilities. Notwithstanding anything to the contrary contained in this Agreement, the Amorcyte Stockholders may not seek indemnification with respect to any claim for Damages until the aggregate amount of all Damages for which the Amorcyte Stockholders are seeking indemnification under Section 8.2 equals or exceeds the Threshold whereupon the Amorcyte Stockholders, through the Amorcyte Representative, shall be entitled to seek indemnification with respect to all such Damages exceeding the Threshold, provided that the Threshold shall not apply to Parent and/or Subco’s failure to pay any Excluded Payments.

(e) The liability of the Amorcyte Stockholders or any Amorcyte Stockholder(s) of the Knowledge Group to the Parent for all Damages for which indemnification is provided hereunder shall not exceed the Escrow Account, except for any claims of fraud, willful breach, intentional misconduct or intentional misrepresentation. The liability of the Parent to the Amorcyte Stockholders for all Damages for which indemnification is provided hereunder shall not exceed $2,000,000, except for any claims of fraud, willful breach, intentional misconduct or intentional misrepresentation and except for any failure by Parent and/or Subco to pay any Excluded Payments. Any claim for fraud, willful breach, intentional misconduct or intentional misrepresentation, may be asserted only against the applicable Amorcyte Stockholder to which such claim relates. Notwithstanding any provision herein to the contrary, no limitation on a party’s liability provided for herein shall apply in the event of the fraudulent conduct, willful breach, intentional misconduct, or intentional misrepresentation of such party.

(f) If and to the extent any provision of Section 8.2(a) is unenforceable for any reason, the Amorcyte Stockholders (to the extent of the Escrow Account other than in the case of fraud) shall make the maximum contribution to the payment and satisfaction of any Damages for which indemnification is provided for in Section 8.2(a) which is permissible under applicable Laws, such amount not to exceed the amount otherwise available under this Agreement if such provision were enforceable. If and to the extent any provision of Section 8.2(b) is unenforceable for any reason, the Parent hereby agrees to make the maximum contribution to the payment and satisfaction of any Damages for which indemnification is provided for in Section 8.2(b) which is permissible under applicable Laws, such amount not to exceed the amount otherwise available under this Agreement if such provision were enforceable.

-56-

(g) For the purposes of determining the amount of any Damages related to a breach of any representation or warranty, the representations and warranties set forth in this Agreement shall be considered without regard to any “material,” “Material Adverse Effect”, or similar qualifications set forth therein.

Section 8.3 Procedures for Third Party Claims. In the case of any claim for indemnification arising from a claim of a third party, an Indemnified Party shall give prompt written notice, following such Indemnified Party’s receipt of such claim or demand, to the Indemnifying Party of any claim or demand of which such Indemnified Party has knowledge and as to which it may request indemnification hereunder; provided, however, that failure to give such notice will not affect such Indemnified Party’s rights furnished hereunder unless, and then solely to the extent that, the rights of the parties from whom indemnity is sought are materially prejudiced as a result of such failure. The Indemnifying Party shall have the right to defend and to direct the defense against any such claim or demand, in its name or in the name of the Indemnified Party, as the case may be, at the expense of the Indemnifying Party, and with counsel selected by the Indemnifying Party provided that the Indemnifying Party shall have provided the Indemnified Party with the prior written assumption, in form and substance reasonably acceptable to the Indemnified Party, by the Indemnifying Party of any and all liability with respect to the matter in controversy, unless (i) such claim or demand seeks an order, injunction or other equitable relief against the Indemnified Party, or (ii) the Indemnified Party shall have reasonably concluded that (x) there is a conflict of interest between the Indemnified Party and the Indemnifying Party in the conduct of the defense of such claim or demand or (y) the Indemnified Party has one or more defenses not available to the Indemnifying Party. Notwithstanding anything in this Agreement to the contrary, the Indemnified Party shall, at the expense of the Indemnifying Party, cooperate with the Indemnifying Party, and keep the Indemnifying Party fully informed, in the defense of such claim or demand. The Indemnified Party shall have the right to participate in the defense of any claim or demand with counsel employed at its own expense; provided, however, that, in the case of any claim or demand described in clause (i) or (ii) of the second preceding sentence or as to which the Indemnifying Party shall not in fact have employed counsel to assume the defense of such claim or demand, the reasonable fees and disbursements of such counsel shall be at the expense of the Indemnifying Party. The Indemnifying Party shall have no indemnification obligations with respect to any such claim or demand which shall be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The Indemnifying Party shall not settle any such claim without the prior written consent of the Indemnified Party, unless such claim solely involves a claim for monetary Damages and such settlement is accompanied by a document releasing the Indemnified Party from all liability with respect to the matter in controversy.

Section 8.4 Escrow Account. Upon approval of this Agreement the Amorcyte Stockholders shall be deemed to have consented to the right of Parent or any Parent Indemnified Party to collect from the Escrow Account the amount of any Damages payable to the Parent or any of the Parent Indemnified Parties in accordance with this Article VIII as and when the Parent or any of the Parent Indemnified Parties incurs or suffers such Damages.

(a) Escrow Period; Release of Escrow Account. The Escrow Account shall commence on the Closing Date and terminate on the date (the “Termination Date”) which is two (2) years and one day after the Closing Date (the “Escrow Period”).

-57-

(i) An aggregate of up to 20% of the Base Stock Consideration in the Escrow Account may be released from the Escrow Account and distributed to the Amorcyte Representative for distribution to the Amorcyte Securityholders in accordance with their proportional interests six (6) months after the Closing Date, provided, however, that the Parent shall not be required to release any shares of Parent Common Stock then being held with respect to pending claims. Shares subject to pending claims will be released to the Amorcyte Representative for distribution to the applicable Amorcyte Stockholders when the pending claim is finally resolved.

(ii) As soon as practicable after the one year anniversary of the Closing Date (the “One-Year Release Date”), the Parent shall direct the Escrow Agent to release and distribute to the Amorcyte Representative for distribution to the Amorcyte Securityholders in accordance with the terms of this Agreement all shares of Parent Common Stock then remaining in the Escrow Account except as follows: If no indemnification claims have been asserted by the Parent prior to the One-Year Release Date, then Parent Common Stock with a Current Value of $1,250,000 shall remain in the Escrow Account until the Termination Date. If any indemnification claims have been asserted by the Parent prior to the One-Year Release Date, then Parent Common Stock with a Current Value equal to the sum of (i) $2,500,000 plus (ii) the amount of any then pending indemnification claims shall remain in the Escrow Account until the Termination Date. For purposes of this paragraph, “Current Value” means the Parent Per Share Value.

(iii) As soon as practical after the Termination Date, the Parent shall direct the Escrow Agent to release and distribute to the Amorcyte Representative for distribution to the Amorcyte Securityholders in accordance with this Agreement all shares of Parent Common Stock then remaining in the Escrow Account; provided that Parent Common Stock representing 120% of the maximum amount of any claim made by the Parent pursuant to Article VIII during the Escrow Period shall be withheld and remain in the Escrow Account pending resolution of such claim; provided, further, that the Parent Common Stock in the Escrow Account which is necessary to satisfy any unsatisfied claims specified in any Parent Notice theretofore delivered to the Escrow Agent prior to the termination of the Escrow Period with respect to facts and circumstances existing prior to the expiration of the Escrow Period, shall remain in the Escrow Account until such claims have been resolved. Parent shall direct the Escrow Agent to promptly distribute to the Amorcyte Representative for distribution to Amorcyte’s former Amorcyte Securityholders any portion of the Escrow Account at the Termination Date for which there is no claim pending or unsatisfied pursuant to this Article VIII. All shares of Parent Common Stock in the Escrow Account shall have been registered on the Form S-4.

(b) Claims Upon Escrow Account. Subject to the provisions of this Section 8.4, the Parent or Subco may make claims upon the Escrow Account by delivering to the Escrow Agent at any time on or before the last day of the Escrow Period a notice signed by a representative of Parent or Subco (a “Parent Notice”) specifying in reasonable detail the individual items of Damages for which indemnification is being sought. Thirty (30) calendar days after receipt by the Escrow Agent of a Parent Notice, the Escrow Agent shall deliver to Parent, the number of shares of Parent Common Stock held in the Escrow Account having a Current Value equal to such Damages. Parent shall, concurrent with the sending of any Parent Notice to the Escrow Agent, provide a copy of such Parent Notice to the Amorcyte Representative. Any payments made to an Indemnified Person pursuant to this Article VIII or the Escrow Agreement shall be treated as an adjustment to the total consideration being paid hereunder for Tax purposes.

-58-

(i) If the Amorcyte Representative shall deliver a written objection to a Parent Notice to Parent and the Escrow Agent within thirty (30) calendar day period after Parent or Subco’s delivery thereof, then Parent and the Amorcyte Representative shall use their good faith efforts to resolve such dispute. If Parent and the Amorcyte Representative resolve such dispute, the parties shall deliver a written notice to the Escrow Agent directing the delivery of the applicable portion of the Escrow Account based upon such resolution. In the event that no objection is made by the Amorcyte Representative as provided herein, the Amorcyte Representative, Amorcyte and the Amorcyte Stockholders shall have irrevocably waived any right to object to such Parent Notice.

(ii) If timely notice of such an objection is given and Parent and the Amorcyte Representative are unable to resolve the applicable dispute within thirty (30) days after the Amorcyte Representative objects to such Parent Notice, either Parent or the Amorcyte Representative may, by written notice to the other and the Escrow Agent, demand arbitration of such dispute. Any such arbitration shall be conducted by JAMS/Endispute, Inc. or such other alternative dispute service (“Arbitration Service”) as shall be reasonably acceptable to Parent and the Amorcyte Representative. The Arbitration Service shall select one (1) arbitrator reasonably acceptable to both Parent and the Amorcyte Representative who shall be expert in the area in dispute. The decision by the arbitrator shall be binding and conclusive and, notwithstanding any other provisions of this Section 8.4, the Escrow Agent shall be entitled to act in accordance with such decisions and make delivery of the Escrow Account in accordance therewith. The arbitration shall be held in New York, New York. The costs of any such arbitration shall be borne one-half by the Parent and one-half by the Amorcyte Stockholders (out of the Escrow Account to the extent available after all claims have been satisfied and shares released). Judgment upon any award rendered by the arbitrator may be entered in any court of competent jurisdiction.

Section 8.5 Amorcyte Representative.

(a) By approval of the First Merger at the Amorcyte Meeting, each Amorcyte Stockholder shall be deemed to irrevocably constitute and appoint the Amorcyte Representative as such Amorcyte Stockholder’s attorney-in-fact and agent in connection with the transactions contemplated by this Agreement and the Escrow Agreement. This power is irrevocable and coupled with an interest, and shall not be affected by the death, incapacity, illness or other inability to act of any Amorcyte Stockholder. Each Amorcyte Stockholder hereby irrevocably grants the Amorcyte Representative full power and authority on behalf of such Amorcyte Stockholder, including, but not limited, to:

(i) execute and deliver, and to accept delivery of, such documents as may be deemed by the Amorcyte Representative, in its sole discretion, to be appropriate to consummate the transactions contemplated by this Agreement or the Escrow Agreement;

-59-

(ii) certify as to the accuracy of the representations and warranties of the Company and of such Amorcyte Stockholder under, or pursuant to the terms of, this Agreement and to deliver such documents, instruments, certificates or agreements contemplated by this Agreement on behalf of such Amorcyte Stockholder;

(iii) (A) dispute or refrain from disputing any claim made by the Parent and Subco under this Agreement; (B) negotiate and compromise any dispute that may arise under, and to exercise or refrain from exercising any remedies available under, this Agreement and (C) execute any settlement agreement, release or other document with respect to such dispute or remedy;

(iv) waive any closing condition contained in Article VII and give or agree to any and all consents, waivers, amendments or modifications deemed by the Amorcyte Representative, in its sole discretion, to be necessary or appropriate under this Agreement or the Escrow Agreement, and, in each case, to execute and deliver any documents that may be necessary or appropriate in connection therewith.

(v) enforce any claim against the Parent and Subco arising under this Agreement;

(vi) engage attorneys, accountants and agents at the expense of the Amorcyte Stockholders;

(vii) exercise all rights of, and take all actions that may be taken by, the Amorcyte Stockholders or any of them hereunder or under the Escrow Agreement; and

(viii) give such instructions and to take such action or refrain from taking such action as the Amorcyte Representative deems, in his sole discretion, necessary or appropriate to carry out the provisions of, and to consummate the transactions contemplated by, this Agreement.

(b) The Amorcyte Representative shall not be liable for any act done or omitted hereunder as Amorcyte Representative while acting in good faith and in the exercise of reasonable judgment. The Amorcyte Securityholders shall indemnify the Amorcyte Representative and hold the Amorcyte Representative harmless against any loss, liability or expense incurred without gross negligence or willful misconduct on the part of the Amorcyte Representative and arising out of or in connection with the acceptance or administration of the Amorcyte Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Amorcyte Representative. This indemnification shall survive termination of this Agreement. A decision, act, consent or instruction of the Amorcyte Representative, including an amendment, extension or waiver of this Agreement, shall constitute a decision of the Amorcyte Stockholders and shall be final, binding and conclusive upon the Amorcyte Representative; and the Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Amorcyte Representative as being the decision, act, consent or instruction of the Amorcyte Stockholders. The Amorcyte Representative may in all questions arising under this Agreement seek advice of legal counsel, and for anything done, omitted or suffered in good faith by the Amorcyte Representative in accordance with such advice, the Amorcyte Representative shall not be liable to any Amorcyte Securityholder. The Escrow Agent and Parent are hereby relieved from any liability to any person for any decision, act, consent or instruction of the Amorcyte Representative.

-60-

(c) In no event shall the Amorcyte Representative be liable hereunder or in connection herewith to any Amorcyte Stockholder for any indirect, punitive, special or consequential damages.

(d) Without limiting in any way any other provision of this Agreement, the Amorcyte Representative is authorized to, without limitation, engage counsel, and such accountants and other advisors and incur such other expenses in connection with this Agreement and the transactions contemplated hereby or thereby as the Amorcyte Representative may in his sole discretion deem appropriate. The Amorcyte Representative shall be entitled to reimbursement of all expenses incurred in connection with its duties as Amorcyte Representative hereunder from the Amorcyte Securityholders in proportion to the aggregate consideration received by each of the respective Amorcyte Securityholders from Parent. If an Amorcyte Securityholder shall default in his, her or its obligations to reimburse the Amorcyte Representative hereunder, the Amorcyte Representative shall be entitled to withhold from distribution to the defaulting Amorcyte Securityholder an amount equal to such defaulted obligation.

(e) In the performance of its duties hereunder, the Amorcyte Representative shall be entitled to (i) rely upon any document or instrument reasonably believed to be genuine, accurate as to content and signed by any Amorcyte Stockholder or any party hereunder and (ii) assume that any person purporting to give any notice in accordance with the provisions hereof has been duly authorized to do so.

(f) Notwithstanding any other provision herein to the contrary, the Parent and all of its Affiliates shall be able to rely conclusively on the instructions and decisions of the Amorcyte Representative as to any matter requiring action or decision by Amorcyte or the Amorcyte Securityholders under this Agreement or the Escrow Agreement, notwithstanding any dispute or disagreement among the Amorcyte Securityholders, without any liability to, or obligation to inquire of, any Amorcyte Securityholder, and notwithstanding any Knowledge on the part of the Parent and Subco of any such dispute or disagreement. Amorcyte and the Amorcyte Securityholders shall not have any cause of action against the Parent or any of its Affiliates for any action taken by the Parent in reliance upon the instructions or decisions of the Amorcyte Representative. All actions, decisions and instructions of the Amorcyte Representative shall be conclusive and binding upon Amorcyte and the Amorcyte Securityholders and, in the absence of fraud or intentional misconduct, neither Amorcyte nor the Amorcyte Securityholders shall have any right to object, dissent, protest or otherwise contest the same or have any cause of action against the Amorcyte Representative for any action taken, decision made or instruction given by the Amorcyte Representative under this Agreement, the Escrow Agreement or any other agreement contemplated hereby.

(g) By approval of the First Merger at the Amorcyte Meeting, each Amorcyte Securityholder shall be deemed to agree that:

(i) notice to the Amorcyte Representative, delivered in the manner provided herein, shall be deemed to be notice to each Amorcyte Securityholder for the purposes of this Agreement;

-61-

(ii) the authority of the Amorcyte Representative, as described in this Agreement and the Escrow Agreement, shall be effective until the rights and obligations of the Amorcyte Representative under this Agreement shall terminate by virtue of the termination of any and all rights and obligations of such Amorcyte Securityholder to the Parent and all of its Affiliates under this Agreement;

(iii) if the Amorcyte Representative is removed, resigns or otherwise ceases to function in his capacity as such for any reason whatsoever, and if no successor is appointed by a majority-in-interest of the Amorcyte Securityholders based on their proportional percentage of the Stock Consideration within thirty (30) days of such removal, resignation or otherwise, then the Parent and Subco shall have the right to appoint a Amorcyte Representative to serve as described in this Agreement (who shall be an Amorcyte Securityholder) and, under such circumstances, the Parent and Subco and the Escrow Agent shall be entitled to rely on all actions taken by such Amorcyte Representative; and

(iv) the Amorcyte Representative shall not be liable to any Amorcyte Securityholder for Damages with respect to any action taken or any omission by the Amorcyte Representative pursuant to this Section 8.5 or the Escrow Agreement, except to the extent such Damages are caused by the Amorcyte Representative’s gross negligence or willful misconduct.

(h) Each Amorcyte Securityholder shall be deemed to have agreed that, notwithstanding the foregoing, at the request of the Parent and Subco, he/she/it shall take all actions necessary or appropriate to consummate the transactions contemplated by this Agreement (including, without limitation, delivery of his/her/its shares of Amorcyte Securities and/or the Letter of Transmittal contemplated by this Agreement and acceptance of the consideration payable pursuant to this Agreement in escrow at Closing) individually on his/her/its own behalf. As a condition to receipt of each Amorcyte Securityholder’s pro rata portion of the Warrants, the Adjusted Stock Consideration, the Contingent Shares, and the Earn Out Payments, if applicable, each Amorcyte Securityholder shall execute and deliver to the Parent and its transfer agent the Letter of Transmittal, duly endorsed (signature guaranteed by a commercial bank).

(i) Any claim, action, suit or other proceeding, whether at law or in equity, to enforce any right, benefit or remedy granted to Amorcyte Stockholders under this Agreement shall be asserted, brought, prosecuted, or maintained only by the Amorcyte Representative on behalf of the Amorcyte Stockholders. Any claim, action, suit or other proceedings, either at law or in equity, to enforce any right, benefit or remedy granted under this Agreement, including, without limitation, any right of indemnification provided in this Agreement, may be asserted, brought, prosecuted or maintained by the Parent or Subco against the Amorcyte Stockholder by service of process on the Amorcyte Representative and without the necessity of serving process on, or otherwise joining or naming any other Amorcyte Stockholder as a defendant in such action, suit or other proceeding. With respect to any matter contemplated by this Section, an Amorcyte Stockholder shall be bound by any determination in favor of or against the Amorcyte Representative or the terms of any settlement or release to which the Amorcyte Representative shall become a party.

-2-

(d) To the extent that any Lock Up Stockholder holds any Options, Warrants or other rights to acquire securities of the Company, the Lock Up Stockholder hereby consents and agrees to the treatment of such Options, Warrants and any other rights to acquire securities of the Company as provided in the Merger Agreement.

(e) Each of the Lock Up Stockholders agrees that notwithstanding anything else in any agreement to the contrary, (i) no further consent of or notice to the Lock Up Stockholders shall be required in connection with the Company’s execution of the Merger Agreement or consummation of the transactions contemplated thereby, including, without limitation, the First Merger and (ii) neither the Company’s execution of the Merger Agreement or consummation of the transactions contemplated thereby, including, without limitation, the First Merger, shall trigger, or give any legal rights except as contemplated by the Merger Agreement. Upon request of the Company or the Parent, each Lock Up Stockholder agrees to execute a form of proxy in favor of the Company.

4. Covenants, Representations and Warranties of the Company and each Lock Up Stockholder. The Company represents and warrants to Parent, and each Lock Up Stockholder represents and warrants to Parent severally with respect to the securities held by it, (a) that to the best of its knowledge, the signatories to this Agreement, as listed on Schedule A, (i) constitute the holders of at least 51% of each class of equity securities of the Company, which percentage is and will be at the record date for any shareholders meeting or consent with respect to the Merger, sufficient to constitute all shareholders’ consents or votes needed to approve the Merger Agreement and the First Merger and (ii) constitute all of the directors of the Company, and (b) that there are no other classes of equity or persons with voting, consent or approval rights with respect to the First Merger under the certificate of incorporation or by-laws of the Company, or under any investor rights agreement, subscription agreement, voting trust, trust or other agreement or understanding, so that the First Merger and all matters related thereto will have received all requisite approvals under any law, organizational document or agreement upon approval by the signatories hereto at the Amorcyte Special Meeting. Each of the Lock Up Stockholders hereby severally represents and warrants (with respect to such Lock Up Stockholder only and not with respect to each other Lock Up Stockholder) to, and agrees with, Parent as follows:

This Lock Up Agreement has been duly and validly executed and delivered by such Lock Up Stockholder and constitutes a valid and binding agreement enforceable against such Lock Up Stockholder in accordance with its terms. There is no beneficiary or holder of a voting trust certificate or other interest of any trust of which such Lock Up Stockholder is a trustee whose consent is required for the execution and delivery of this Lock Up Agreement or the consummation by such Lock Up Stockholder of the transactions contemplated hereby. If such Lock Up Stockholder is married and such Lock Up Stockholder’s Shares constitute community property, this Lock Up Agreement has been duly authorized, executed and delivered by, and constitutes a valid and binding agreement of, such Lock Up Stockholder’s spouse, enforceable against such person in accordance with its terms.

(c)

No Conflicts. (i) Except as may be required under Section 13 of the Exchange Act, no filing with, and no permit, authorization, consent or approval of, any state or federal public body or authority is necessary for the execution of this Lock Up Agreement by such Lock Up Stockholder and the consummation by such Lock Up Stockholder of the transactions contemplated hereby and (ii) none of the execution and delivery of this Lock Up Agreement by such Lock Up Stockholder, the consummation by such Lock Up Stockholder of the transactions contemplated hereby or compliance by such Lock Up Stockholder with any of the provisions hereof shall (A) conflict with or result in any breach of the organizational documents of such Lock Up Stockholder (if applicable), (B) result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any third party right of termination, cancellation, material modification or acceleration) under any of the terms, conditions or provisions of any note, bond, mortgage, indenture, license, contract, commitment, arrangement, understanding, agreement or other instrument or obligation of any kind to which such Lock Up Stockholder is a party or by which such Lock Up Stockholder or any of its properties or assets may be bound, or (C) violate any order, writ injunction, decree, judgment, order, statute, rule or regulation applicable to such Lock Up Stockholder or any of its properties or assets.

-4-

(d)

No Encumbrances. Such Lock Up Stockholder’s Shares at all times during the term hereof will be Beneficially Owned by such Lock Up Stockholder, free and clear of all liens, claims, security interests, proxies, voting trusts or agreements, understandings or arrangements or any other encumbrances whatsoever.

(e)

No Solicitation. Such Lock Up Stockholder agrees not to take any action inconsistent with or in violation of the Merger Agreement.

(f)

Restriction on Transfer; Restriction on Redemption; Proxies and Non-interference.

Reliance by Parent. Such Lock Up Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon such Lock Up Stockholder’s execution and delivery of this Lock Up Agreement.

See attached.

Exhibit B

ESCROW AGREEMENT

THIS ESCROW AGREEMENT (“Agreement”) is made and entered into as of _________________, 2011, by and among NeoStem, Inc., a Delaware corporation (“Parent”), Amorcyte, Inc., a Delaware corporation (the “Company”), ▇▇▇▇ ▇▇▇▇▇▇▇ (the “Amorcyte Representative”), as representative of the stockholders of the Company identified from time to time on Schedule 1 hereto, and Continental Stock Transfer & Trust Company, a New York corporation (the “Escrow Agent”).

RECITALS

WHEREAS, Parent, AMO Acquisition Company, I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Subco”), AMO Acquisition Company II, LLC, a Delaware limited liability company and a wholly-owned subsidiary of Parent (“Subco II”), and the Company have entered into an Agreement and Plan of Merger dated as of July 13, 2011 (the “Merger Agreement”), pursuant to which, among other things, (i) Subco is merging with and into the Company, with the Company surviving the merger (the “First Merger”), (ii) within ninety (90) days after the First Merger, the Company, as the surviving company of the First Merger, is merging with and into Subco II, with Subco II surviving the merger as the Surviving Company (the “Second Merger” and together with the First Merger, the “Mergers”), and (iii) certain issuances of Parent Common Stock are to be made by Parent to the Amorcyte Representative on behalf of the Amorcyte Stockholders. A copy of the Merger Agreement is attached hereto as Exhibit A;

WHEREAS, the Merger Agreement contemplates the establishment of an escrow account to secure certain rights of the Parent Indemnified Parties to indemnification and reimbursement as provided in the Merger Agreement; and

WHEREAS, pursuant to Section 8.5 of the Merger Agreement, ▇▇▇▇ ▇▇▇▇▇▇▇ has been irrevocably appointed by the Amorcyte Stockholders to serve as the Amorcyte Representative in connection with all matters under this Agreement and the resolution of all claims for Damages under the Merger Agreement.

AGREEMENT

The parties, intending to be legally bound, agree as follows:

Section 1. Defined Terms.

1.1 Capitalized terms used and not defined in this Agreement shall have the meanings given to them in the Merger Agreement.

1.2 As used in this Agreement, the term “Amorcyte Stockholders” refers to the Persons who were stockholders of the Company immediately prior to the First Effective Time or to which the rights under this Agreement have been assigned as set forth herein. “Escrowed Shares” refers to the 6,821,283 shares of Parent Common Stock being issued as the Base Stock Consideration under the Merger Agreement.

Section 2. Escrow and Indemnification.

2.1 Appointment of Escrow Agent; Shares and Stock Powers Placed in Escrow. Continental Stock Transfer & Trust Company is hereby appointed to serve as Escrow Agent hereunder, and Continental Stock Transfer & Trust Company hereby agrees to serve as Escrow Agent hereunder. In accordance with the Merger Agreement, promptly following the First Effective Time, (a) Parent shall issue certificates for the Escrowed Shares registered in the name of the Escrow Agent evidencing 6,821,283 shares of Parent Common Stock to be held in escrow under this Agreement, and shall cause such certificates to be delivered to the Escrow Agent, and (b) the Amorcyte Representative shall deliver to the Escrow Agent an “assignment separate from certificate” (“Stock Power”) endorsed by him in blank. Such endorsement by the Amorcyte Representative shall have been guaranteed by a national bank or an NYSE-Amex member firm.

2.2 Escrow Account. The Escrowed Shares being held in escrow pursuant to this Agreement, together with any distributions on the Escrowed Shares, shall collectively constitute an escrow fund securing the indemnification rights of Parent and the other Parent Indemnified Parties under the Merger Agreement. The Escrow Agent agrees to accept delivery of the Escrowed Shares and to hold the Escrowed Shares in a separate escrow account (such account, the “Escrow Account”), subject to the terms and conditions of this Agreement and the Merger Agreement.

2.3 Voting of Escrow Shares. The Escrow Agent, as record owner of the Escrowed Shares, shall exercise all voting rights with respect to such Escrowed Shares in accordance with Section 3.5 of the Merger Agreement, upon receipt of written instructions from the Amorcyte Representative. The Escrow Agent is not obligated to distribute to the Amorcyte Stockholders or to the Amorcyte Representative any proxy materials or other documents relating to the Escrowed Shares received by the Escrow Agent from Parent.

2.4 Reports. Upon the request of either Parent or the Amorcyte Representative, the Escrow Agent shall provide a statement to the requesting party that describes any deposit, distribution or investment activity or deductions with respect to shares of Parent Common Stock held in the Escrow Account in addition to quarterly account statements from the Escrow Agent.

2.5 Dividends, Etc. Parent and the Amorcyte Representative, on behalf of each of the Amorcyte Stockholders, agree that any shares of Parent Common Stock or other property (including ordinary cash dividends) distributable or issuable (whether by way of dividend, stock split or otherwise) in respect of or in exchange for any Escrowed Shares (including pursuant to or as a part of a merger, consolidation, acquisition of property or stock, reorganization or liquidation involving Parent) shall not be distributed or issued to the beneficial owners of such Escrowed Shares, but rather shall be distributed or issued to and held by the Escrow Agent in the Escrow Account. Any securities or other property received by the Escrow Agent in respect of any Escrowed Shares held in escrow as a result of any stock split or combination of shares of Parent Common Stock, payment of a stock dividend or other stock distribution in or on shares of Parent Common Stock, or change of Parent Common Stock into any other securities pursuant to or as a part of a merger, consolidation, acquisition of property or stock, reorganization or liquidation involving Parent, or otherwise, shall be held by the Escrow Agent as part of the Escrow Account.

-2-

2.6 Transferability. Except as expressly provided for herein or by operation of law, the interests of the Amorcyte Stockholders in the Escrow Account shall not be assignable or transferable.

2.7 Trust Fund. The Escrow Account shall be held as trust funds and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of Escrow Agent, any Amorcyte Stockholder or Parent, respectively, or of any party hereto. The Escrow Agent shall hold and safeguard the Escrow Account until the Escrow Termination Date (as defined in Section 3.3) or earlier distribution in accordance with this Agreement.

Section 3. Release of Escrow Shares.

3.1 General. (X) Within ten (10) calendar days after receiving either (a) written instructions from the Parent (a “Parent Notice”) which have not been objected to by the Amorcyte Representative within thirty (30) calendar days after the Parent’s delivery of such Parent Notice to the Amorcyte Representative, (b) joint written instructions from Parent and the Amorcyte Representative (“Joint Instructions”), (c) a decision and/or award from the Arbitrator (an “Arbitration Award”) or (d) an order issued by a court of competent jurisdiction (a “Court Order”) relating to the release of any Escrowed Shares from the Escrow Account or (Y) in accordance with Section 3.3 hereof, the Escrow Agent shall release or cause to be released any such Escrowed Shares and any other amounts from the Escrow Account, in the amounts, to the Persons and in the manner set forth in such Parent Notice, Joint Instructions, Arbitration Award, Court Order or as provided in Section 3.3, as applicable. If a Parent Notice is sent under Section 8.4 of the Merger Agreement and such Parent Notice is not disputed as provided in Section 8.4 within thirty (30) calendar days, the Escrow Agent shall make the distribution requested by the Parent Notice without action by the Amorcyte Representative.

3.2 Pro Rata Distributions. For purposes of this Agreement, all distributions to the Amorcyte Stockholders shall be pro rata distributions made based on the percentages set forth on Schedule 1, as may be amended from time to time pursuant to Section 9.8 of this Agreement, except that no fractional shares shall be issued, and all amounts released from the Escrow Account and distributed to the Amorcyte Representative on behalf of the Amorcyte Stockholders shall be rounded up or down pursuant to Section 3.4(e) of the Merger Agreement.

The Company and the Amorcyte Representative represent and warrant that Schedule 1 attached hereto (the “Percentage Certification”) accurately reflects each Amorcyte Stockholder’s percentage ownership interest in the Company immediately prior to the consummation of the First Merger.

-3-

3.3 Release of the Escrowed Shares.

(a) Within ten (10) Business Days following the six (6) month anniversary of the Closing Date (the “Six-Month Release Date”), the Escrow Agent shall deliver to the Amorcyte Representative for distribution to the Amorcyte Stockholders in accordance with the Percentage Certification as of the Six-Month Release Date an aggregate of up to 20% of the Base Stock Consideration in the Escrow Account (the “Six-Month Release Amount”), provided, however, that if there are claims for Damages against the Escrow Account that have not been finally resolved and paid as of the Six-Month Release Date, the Escrow Agent shall release and deliver to the Amorcyte Representative for distribution to the Amorcyte Stockholders only a number of Escrowed Shares equal to the positive difference, if any, between (i) the Six-Month Release Amount and (ii) the number of Escrowed Shares then being held with respect to pending claims against the Escrow Account. The Escrow Agent shall deliver Escrowed Shares subject to pending claims that would have otherwise been released and delivered to the Amorcyte Representative pursuant to this Section 3.3(a) when the pending claims are finally resolved.

(b) Within ten (10) Business Days following the one year anniversary of the Closing Date (the “One-Year Release Date”), the Escrow Agent shall deliver to the Amorcyte Representative for distribution to the Amorcyte Stockholders in accordance with the Percentage Certification as of the One-Year Release Date the balance of shares of Parent Common Stock then held in the Escrow Account at such time except as follows: If no claims for Damages have been asserted against the Escrow Account by the Parent prior to the One-Year Release Date, then the Escrow Agent shall retain in the Escrow Account Parent Common Stock with a Current Value of $1,000,000 until the date that is two (2) years and one day after the Closing Date (the “Escrow Termination Date”). If any claims for Damages have been asserted against the Escrow Account by the Parent prior to the One-Year Release Date, then the Escrow Agent shall retain in the Escrow Account Parent Common Stock with a Current Value equal to the sum of (i) $2,000,000 plus (ii) the amount of any then pending and unresolved claims until the Escrow Termination Date.

(c) Within ten (10) Business Days following the Escrow Termination Date, if there are no claims for Damages pending against the Escrow Account, the Escrow Agent shall deliver to the Amorcyte Representative for distribution to the Amorcyte Stockholders in accordance with the Percentage Certification as of the Escrow Termination Date the balance of shares of Parent Common Stock and other property held in the Escrow Account at such time. If, on the Escrow Termination Date, there are claims for Damages against the Escrow Account that have not been finally resolved, then, within ten (10) Business Days of the Escrow Termination Date, the Escrow Agent shall deliver to the Amorcyte Representative for distribution to the Amorcyte Stockholders the excess, if any, by which the value of the amounts held in the Escrow Account exceed an amount equal to 120% of the maximum amount of any claims for Damages against the Escrow Account that have not been finally resolved and paid at such time. Thereafter, final distributions of the Escrow Account shall be made in accordance with Section 3.1(X)(a), (b), (c) or (d), as applicable.

-4-

3.4 Distributions. Whenever a distribution of a number of shares of Parent Common Stock is to be made pursuant to the terms of this Agreement, the Escrow Agent shall requisition the appropriate number of shares from Parent’s stock transfer agent, delivering to the transfer agent the appropriate stock certificates accompanied by the respective Stock Powers, together with the specific instructions, as appropriate. Within 5 Business Days prior to the date the Escrow Agent is required to make a distribution of shares of Parent Common Stock or other property (including ordinary cash dividends) to the Amorcyte Representative pursuant to the terms of this Agreement, the Escrow Agent shall provide the Amorcyte Representative and the Parent with a notice specifying that a distribution will be made and requesting that the Amorcyte Representative update the then current Schedule 1 to this Agreement. The Escrow Agent shall make the appropriate distributions to the Amorcyte Representative for distribution to the Persons listed on such updated Schedule 1 in accordance with the terms hereof. Notwithstanding anything to the contrary set forth herein, the Escrow Agent shall not be obligated to make any distribution under this Agreement unless it has received from the Amorcyte Representative an updated Schedule 1 to this Agreement as provided herein. Any distributions to Parent pursuant to the terms of this Agreement shall be made to the address set forth in Schedule 2 hereto.

3.5 Disputes. All disputes, claims, or controversies arising out of or relating to Section 3 of this Agreement that are not resolved by mutual agreement between Parent and the Amorcyte Representative shall be resolved solely and exclusively as set forth in Section 8.4 of the Merger Agreement by the Amorcyte Representative and the Parent.

Section 4. Fees and Expenses.

The Escrow Agent shall be entitled to receive, from time to time, fees in accordance with Schedule 3. In accordance with Schedule 3, the Escrow Agent will also be entitled to reimbursement for reasonable and documented out-of-pocket expenses incurred by the Escrow Agent in the performance of its duties hereunder and the execution and delivery of this Agreement. All such fees and expenses shall be paid by Parent.

Section 5. Limitation of Escrow Agent’s Liability.

5.1 The Escrow Agent undertakes to perform such duties as are specifically set forth in this Agreement only and shall have no duty under any other agreement or document, and no implied covenants or obligations shall be read into this Agreement against the Escrow Agent. The Escrow Agent shall incur no liability with respect to any action taken by it or for any inaction on its part in reliance upon any notice, direction, instruction, consent, statement or other document believed by it in good faith to be genuine and duly authorized, nor for any other action or inaction except for its own gross negligence or willful misconduct. In all questions arising under this Agreement, the Escrow Agent may rely on the advice of counsel, and for anything done, omitted or suffered in good faith by the Escrow Agent based upon such advice the Escrow Agent shall not be liable to anyone. In no event shall the Escrow Agent be liable for incidental, punitive or consequential damages.

-5-

5.2 Parent and the Amorcyte Representative, acting on behalf of the Amorcyte Stockholders hereby agree to indemnify the Escrow Agent and its officers, directors, employees and agents for, and hold it and them harmless against, any loss, liability or expense incurred without gross negligence or willful misconduct on the part of Escrow Agent, arising out of or in connection with the Escrow Agent’s carrying out its duties hereunder. This right of indemnification shall survive the termination of this Agreement and the resignation of the Escrow Agent.

Section 6. Termination.

This Agreement shall terminate upon the release by the Escrow Agent of the final amounts held in the Escrow Account in accordance with Section 3.

Section 7. Successor Escrow Agent.

In the event the Escrow Agent becomes unavailable or unwilling to continue as escrow agent under this Agreement, the Escrow Agent may resign and be discharged from its duties and obligations hereunder by giving its written resignation to the parties to this Agreement. Such resignation shall take effect not less than thirty (30) calendar days after it is given to all the other parties hereto. In such event, Parent may appoint a successor Escrow Agent (acceptable to the Amorcyte Representative, acting reasonably). If Parent fails to appoint a successor Escrow Agent within fifteen (15) calendar days after receiving the Escrow Agent’s written resignation, the Escrow Agent shall have the right to apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent. The successor Escrow Agent shall execute and deliver to the Escrow Agent an instrument accepting such appointment, and the successor Escrow Agent shall, without further acts, be vested with all the estates, property rights, powers and duties of the predecessor Escrow Agent as if originally named as Escrow Agent herein. The Escrow Agent shall act in accordance with written instructions from Parent and the Amorcyte Representative as to the transfer of the Escrow Accounts to a successor Escrow Agent.

Section 8. Amorcyte Representative.

Unless and until Parent and the Escrow Agent shall have received written notice of the appointment of a successor Amorcyte Representative, Parent and the Escrow Agent shall be entitled to rely on, and shall be fully protected in relying on, the power and authority of the Amorcyte Representative to act on behalf of the Amorcyte Stockholders.

Section 9. Miscellaneous.

9.1 Attorneys’ Fees. In any action at law or suit in equity to enforce or interpret this Agreement or the rights of any of the parties hereunder, the prevailing party in such action or suit shall be entitled to receive a reasonable sum for its attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit.

Notwithstanding the foregoing, notices addressed to the Escrow Agent shall be effective only upon receipt. If any notice or other document is required to be delivered to the Escrow Agent and any other Person, the Escrow Agent may assume without inquiry that notice or other document was received by such other Person on the date on which it was received by the Escrow Agent.

9.3 Headings. The bold-faced headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement.

9.4 Counterparts and Exchanges by Facsimile or Other Electronic Transmission. This Agreement may be executed in several counterparts, each of which shall constitute an original and all of which, when taken together, shall constitute one agreement. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or other means of electronic transmission shall be sufficient to bind the parties to the terms and conditions of this Agreement.

9.5 Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

9.6 Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of each of the parties hereto and each of their respective permitted successors and assigns, if any.

9.7 Waiver. No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Person shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Person; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

9.8 Amendment. This Agreement may not be amended, modified, altered or supplemented other than by means of a written instrument duly executed and delivered on behalf of Parent, the Amorcyte Representative and the Escrow Agent; provided, however, that any amendment executed and delivered by the Amorcyte Representative shall be deemed to have been approved by and duly executed and delivered by all of the Amorcyte Stockholders.

9.9 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

9.10 Parties in Interest. Except as expressly provided herein, none of the provisions of this Agreement, express or implied, is intended to provide any rights or remedies to any Person other than the parties hereto and their respective successors and assigns, if any.

9.11 Entire Agreement. This Agreement and the Merger Agreement set forth the entire understanding of the parties hereto relating to the subject matter hereof and supersede all prior agreements and understandings among or between any of the parties relating to the subject matter hereof.

Exhibit C

AMORCYTE WARRANT AGREEMENT

THIS WARRANT AGREEMENT (this “Agreement”), dated as of _________, 2011, is entered into by and between NeoStem, Inc., a Delaware corporation (“NeoStem” or the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Warrant Agent”).

WHEREAS, on __________, 2011, NeoStem consummated a merger (the “Merger”) of its wholly-owned subsidiary, AMO Acquisition Company, Inc. (“Subco”), with and into Amorcyte, Inc., a Delaware corporation (“Amorcyte”), pursuant to an Agreement and Plan of Merger, dated as of July 13, 2011 (as such agreement may be amended from time to time, the “Merger Agreement”), by and among NeoStem, Amorcyte, Subco and AMO Acquisition Company II, LLC, a wholly-owned subsidiary of NeoStem;

WHEREAS, the Merger Agreement provides that the Company will issue warrants to purchase One Million Eight Hundred Eighty-One Thousand Eight (1,881,008) shares of the Company’s common stock, par value $0.001 per share, (the “NeoStem Common Stock”) exercisable over a seven year period at an exercise price of $1.466 per share (the “Warrants” or the “Amorcyte Warrants”);

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, transfer, exchange, redemption and exercise of the Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1. Appointment of Warrant Agent and Depository. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Amorcyte Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. The Company initially appoints the Warrant Agent to act as Depository with respect to the Global Warrants as hereinafter defined.

2. Warrants.

2.1 Issuance of Warrants. Each Amorcyte Warrant shall be (a) issued by book-entry registration only and (b) evidenced by the Global Warrant, substantially in the form of Exhibit A, hereto (individually a “Global Warrant” and together, the “Global Warrants”), respectively, the provisions of which are incorporated herein.

2.2 Execution and Delivery of the Global Warrants.

2.2.1 Each Global Warrant shall be dated and may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Agreement or the respective Warrants, or as may be required to comply with any law or with any rule or regulation made pursuant thereto. The Global Warrants shall be signed on behalf of the Company by its chairman or vice chairman of the Board of Directors of the Company (the “Board of Directors”), the chief financial officer, the president, any vice president, any assistant vice president, the treasurer or any assistant treasurer of the Company, which may but need not be attested to by its secretary or one of its assistant secretaries. Such signatures may be manual or facsimile signatures of such authorized officers and may be imprinted or otherwise reproduced on each Global Warrant. From time to time, in accordance with the Warrant Agent’s customary practices, the Warrant Agent shall send to each Holder (as hereinafter defined) a statement reflecting such Holder’s book-entry position in the Warrants and any changes thereto (the “Warrant Statement”). The terms and conditions of each Global Warrant are incorporated herein by this reference and made a part hereof. Notwithstanding anything contained herein to the contrary, if any terms or conditions of the Global Warrant or the Warrant Statement shall be found to conflict with any terms or conditions of this Agreement, the terms and conditions of the respective Global Warrants shall control except that the Warrant Agent’s procedures relating to the exercise of book-entry interests in the Global Warrants shall control the exercise of the Warrants.

2.2.2 Each Global Warrant shall represent the respective number of outstanding Warrants from time to time endorsed thereon and the respective number of outstanding Warrants represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, exercises and other similar transactions.

2.2.3 No Warrant shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until the Global Warrant has been countersigned by the Warrant Agent by manual or facsimile signature. Such signature by the Warrant Agent upon the Global Warrant executed by the Company shall be conclusive evidence, and the only evidence, that the Global Warrant so countersigned has been duly issued hereunder.

2.2.4 In case any officer of the Company who shall have signed any of the Global Warrants either manually or by facsimile signature shall cease to be such officer before such Global Warrant so signed shall have been countersigned and delivered by the Warrant Agent as provided herein, such Global Warrant may be countersigned and delivered notwithstanding that the person who signed such Global Warrant ceased to be such officer of the Company; and such Global Warrant may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Global Warrant, shall be the proper officers of the Company, although at the date of the execution of this Agreement any such person was not such officer.

-2-

2.2.5 The term “Holder” shall mean, when used with respect to any Warrant, any person in whose name a Warrant is issued at the time such Warrant shall be registered upon the books to be maintained by the Warrant Agent for that purpose.

3. Terms and Exercise of Warrants.

3.1 Exercise Price. For purposes of this Agreement, “Exercise Price” shall mean the initial exercise price for each Warrant as set forth in the Global Warrant, subject to adjustment as provided in the Global Warrant.

3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) specified in the Global Warrant or as the same may be extended as hereinafter provided. Except with respect to the right to receive the Redemption Price if the Warrants have been redeemed (as set forth in the Global Warrant), each Warrant not exercised on or before the expiration date, as set forth in the Global Warrant (the “Expiration Date”), shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date.

3.3 Exercise of Warrants. Warrants may be exercised, at the option of the Holder, in whole or in part, at any time or from time to time during the Exercise Period, by complying with the Warrant Agent’s procedures relating to the exercise of such book-entry interest in the Global Warrant. In addition, the Holder shall deliver to the Company at the then designated office of the Warrant Agent (the “Warrant Agent Office”) (i) the Exercise Form substantially in the form attached to the Global Warrant duly executed by such Holder or its duly authorized agent or attorney (the “Exercise Form”) and (ii) payment of the aggregate Exercise Price. In case an exercise of Warrants is in part only, the Warrant Agent shall make an appropriate adjustment to the account of the Holder to reflect a number of Warrants for the number of shares of NeoStem Common Stock equal (without giving effect to any adjustment thereof) to the number of such shares called for by such Holder’s Warrants prior to such exercise, minus the number of shares designated by the Holder upon such exercise.

3.3.1 Payment. The Holder shall pay the Exercise Price in accordance with the procedures in the Global Warrant and this Agreement.

3.3.2 Procedures and Validity.

(a) Any exercise of a Warrant by a Holder pursuant to the terms of this Agreement shall be irrevocable and shall constitute a binding agreement between the Holder and the Company, enforceable in accordance with its terms.

(b) The Warrant Agent shall:

(i) examine all Exercise Forms and all other documents delivered to it by or on behalf of Holders as contemplated hereunder to ascertain whether or not, on their face, such Exercise Forms and any such other documents have been executed and completed in accordance with their terms and the terms hereof;

-3-

(ii) where an Exercise Form or other document appears on its face to have been improperly completed or executed or some other irregularity in connection with the exercise of the Warrants exists, the Warrant Agent shall endeavor to inform the appropriate parties (including the person submitting such instrument) of the need for fulfillment of all requirements, specifying those requirements which appear to be unfulfilled;

(iii) inform the Company of and cooperate with and assist the Company in resolving any reconciliation problems between the Exercise Forms received and the crediting of Warrants to the respective Holders’ accounts; and

(iv) advise the Company no later than two (2) business days after receipt of an Exercise Form, of (i) the receipt of such Exercise Form and the number of Warrants exercised in accordance with the terms and conditions of this Agreement, (ii) the percentage of the then outstanding Warrants represented by such exercise and (iii) such other information as the Company shall reasonably require.

(c) All questions as to the validity, form and sufficiency (including time of receipt) of an exercised Warrant and any Exercise Form will be determined by the Company in good faith. The Company reserves the right to reject any and all Exercise Forms not in proper form or for which any corresponding agreement by the Company to exchange would, in the opinion of the Company, be unlawful. Moreover, the Company reserves the absolute right to waive any of the conditions to the exercise of Warrants or defects in the exercise thereof with regard to any particular exercise of Warrants. Other than as required in Section 3.3.2(b)(ii) above, neither the Company nor the Warrant Agent shall be under any duty to give notice to the Holders of the Warrants of any irregularities in any exercise of Warrants or any Exercise Form, nor shall it incur any liability for the failure to give such notice.

3.3.3 Issuance of Certificates. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Exercise Price, the Company shall cause its Transfer Agent to issue to the Holder of such Warrant a certificate or certificates representing the number of full shares of NeoStem Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant unless (a) a registration statement under the Securities Act of 1933 (the “Securities Act”) with respect to the NeoStem Common Stock issuable upon exercise of such Warrants is effective and a current prospectus relating to the shares of NeoStem Common Stock issuable upon exercise of the Warrants is available for delivery to the Holders or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the registration requirements of the Securities Act and such securities are qualified for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the registered holder resides. Warrants may not be exercised by, or securities issued to, any Holder in any state in which such exercise or issuance would be unlawful. In the event that a registration statement under the Securities Act with respect to the NeoStem Common Stock underlying the Warrants is not effective or a current prospectus is not available, a Holder shall not be entitled to exercise his, her or its Warrants unless an exemption from registration is available. In the event that during the last 20 business days immediately prior to the Expiration Date both (i) a registration statement with respect to the NeoStem Common Stock underlying the Warrants is not effective or a current prospectus is not available and (ii) the Exercise Price of the Warrants is less than the price at which the NeoStem Common Stock is trading on the NYSE Amex (or if the NeoStem Common Stock is no longer trading on the NYSE Amex, such other stock exchange on which the shares of NeoStem Common Stock trades), the Exercise Period shall automatically be extended for a period of 20 business days after the date that the Company causes a registration statement covering the NeoStem Common Stock underlying the Warrants to be effective and a current prospectus is made available. In no event will the Company be required to “net cash settle” the warrant exercise.

-4-

3.3.4 Valid Issuance. All shares of NeoStem Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.3.5 Date of Issuance. All shares of NeoStem Common Stock so issued shall be registered in the name of the Holder or such other name as shall be designated in the Exercise Form delivered by the Holder. Such shares of NeoStem Common Stock shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become the holder of record of such shares of NeoStem Common Stock as of the date of delivery of the Exercise Form to the Warrant Agent Office duly executed by the Holder thereof and upon the Company’s receipt of payment of the Exercise Price.

4. Adjustments.

4.1 Adjustments Generally. The Exercise Price, the number of shares of NeoStem Common Stock issuable upon exercise of the Warrants and the number of Warrants outstanding are subject to adjustment from time to time upon the occurrence of certain events in accordance with the provisions of the Global Warrant.

4.2 Notices of Changes in Warrant. Upon every adjustment of (i) the Exercise Price, (ii) the number of shares of NeoStem Common Stock issuable upon exercise of the Warrants and (iii) the number of Warrants outstanding, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in the Global Warrant then, in any such event, the Company shall give written notice to each Holder, at the last address set forth for such Holder in the Warrant register maintained by the Warrant Agent, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.3 No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the Holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round up or down to the nearest whole number the number of shares of NeoStem Common Stock to be issued to the Holder.

-5-

4.4 Form of Warrant. The form of Global Warrant need not be changed because of any adjustment pursuant to this Section 4. However, the Company may, at any time, in its sole discretion, make any change in the form of Global Warrant that the Company may deem appropriate and that does not affect the substance thereof.

5. Transfer and Exchange of Warrants.

5.1 Exchange and Transfer.

5.1.1 The Warrant Agent shall keep, at the Warrant Agent Office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrants and exchanges and transfers of outstanding Warrants upon request to exchange or transfer such Warrants, provided, that the Warrant Agent shall have received a written instruction of transfer or exchange in form satisfactory to the Warrant Agent, duly executed by the Holder thereof or by his duly authorized agent or attorney, providing all information required to be delivered hereunder, such signature to be guaranteed by an eligible guarantor institution to the extent required by the Warrant Agent or the Depository. Upon any such registration of transfer, a Warrant Statement shall be issued to the transferee.

5.1.2 No service charge shall be made for any exchange or registration of transfer of Warrants; however, the Warrant Agent and/or the Company may require payment of a sum sufficient to cover any stamp or other tax or other charge that may be imposed in connection with any such exchange or registration of transfer. Neither the Warrant Agent nor the Company shall be required to pay any stamp or other tax or other charge required to be paid in connection with such transfer, and neither the Warrant Agent nor the Company shall be required to issue or deliver any Warrants until it has been established to the Company’s and the Warrant Agent’s satisfaction that such tax or other charge has been paid or that no such tax or other charge is due.

5.1.3 The Warrant Agent shall not effect any exchange or registration of transfer which will result in the issuance of a Warrant evidencing a fraction of a Warrant or a number of full Warrants and a fraction of a Warrant.

5.1.4 All Warrants credited to a Holder’s or transferee’s account upon any exchange or transfer of Warrants in accordance with the provisions of this Agreement shall be the valid obligations of the Company evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrants that were so exchanged or transferred.

5.2 Treatment of Holders of Warrants. Each Holder of Warrants, by accepting the same, consents and agrees with the Company, the Warrant Agent and every subsequent Holder of such Warrants that until the transfer of such Warrants is registered on the books of such Warrant Agent, the Company and the Warrant Agent may treat the registered Holder of such Warrants as the absolute owner thereof for any purpose and as the person entitled to exercise the rights represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

-6-

5.3 Restrictions on Transfers. Notwithstanding anything in this Agreement to the contrary, in no event may any Holder transfer any NeoStem Common Stock received upon the exercise of a Warrant until after the one year anniversary of the date of issuance of the Global Warrant.

5.4 Cancellation of Global Warrant. Promptly following the Expiration Date or at such earlier time that there are no longer outstanding any Warrants, the Global Warrants shall be cancelled or destroyed and the Warrant Agent shall deliver a certificate of such cancellation or destruction to the Company.

6. Redemption. The Warrants may be redeemed, at the option of the Company, in accordance with the provisions of the Global Warrant.

7. Other Provisions Relating to Rights of Holders of Warrants.

7.1 No Rights as Stockholder. No Warrant shall, and nothing contained in this Agreement, in the Global Warrants or in the Warrant Statement shall be construed to, entitle the Holder or any beneficial owner thereof to any of the rights of a holder or beneficial owner of NeoStem Common Stock, including, without limitation, the right to vote or to consent or to receive notice as a stockholder in respect of any meeting of stockholders for the election of directors of the Company or any other matter, to receive dividends on NeoStem Common Stock or any rights whatsoever as stockholders of the Company, until such Warrant is duly exercised in accordance with this Agreement and such Holder is issued the NeoStem Common Stock to which it is entitled in connection therewith.

7.2 Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of NeoStem Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.3 Registration of Common Stock. The Company included the shares of NeoStem Common Stock underlying the Warrants in the registration statement on Form S-4 that was filed with the Securities and Exchange Commission in connection with the Merger (the “Registration Statement”). The Company will use its commercially reasonable efforts to maintain the effectiveness of such Registration Statement or file and maintain the effectiveness of another registration statement covering the shares of NeoStem Common Stock issuable upon exercise of the Warrants at any time that both (a) the Warrants are exercisable and (b) the Exercise Price of the Warrants is less than 105% of the price at which the NeoStem Common Stock is trading on the NYSE Amex (or if the NeoStem Common Stock is no longer trading on the NYSE Amex, such other stock exchange on which the shares of Common Stock trades). In no event will any Holder of a Warrant be entitled to receive a “net cash settlement” in lieu of physical settlement in shares of NeoStem Common Stock regardless of whether the Company complies with this Section 7.3.

-7-

7.4 Limitation on Monetary Damages. In no event shall the Holder of a Warrant be entitled to receive monetary damages for failure to settle any Warrant exercise if the NeoStem Common Stock issuable upon exercise of the Warrants has not been registered with the SEC pursuant to an effective registration statement or if a current prospectus is not available for delivery by the Warrant Agent, provided the Company has fulfilled its obligations under Section 7.3 to use its commercially reasonable efforts to effect the registration under the Securities Act of the NeoStem Common Stock issuable upon exercise of the Warrants. The foregoing limitation on damages shall not apply to an exercise in connection with a redemption of a Warrant.

8. Concerning the Warrant Agent and Other Matters.

8.1 Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of NeoStem Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

8.2 Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1 Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company and to each Holder. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by any Holder of a Warrant, then the Holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to each Holder, the predecessor Warrant Agent and the transfer agent for the NeoStem Common Stock not later than the effective date of any such appointment.

-8-

8.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

8.3 Fees and Expenses of Warrant Agent.

8.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and will reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2 Further Assurances. The Company agrees to perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4 Liability of Warrant Agent.

8.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the General Counsel, President or Chairman of the Board of Directors of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith.

8.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant; nor shall it be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of NeoStem Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of NeoStem Common Stock will when issued be valid and fully paid and nonassessable.

-9-

8.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and, among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all moneys received by the Warrant Agent for the purchase of shares of NeoStem Common Stock through the exercise of Warrants.

9. Miscellaneous Provisions.

as described herein

NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED, OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

Each Warrant (each a “Warrant”) represented hereby, entitles the holder to purchase one share (the “Warrant Share”) of common stock, $.001 par value (the “Common Stock”), of NeoStem, Inc., a Delaware corporation, (the “Corporation”) for the benefit of certain Holders (as defined in the Warrant Agreement) of such Warrants on the following terms. This Global Warrant Certificate represents the number of outstanding Warrants from time to time endorsed hereon and the number of outstanding Warrants represented hereby may from time to time be reduced or increased, as appropriate to reflect exchanges, redemptions, exercises and other similar transactions. This Global Warrant Certificate is issued under and in accordance with the Warrant Agreement, and is subject to the terms and provisions contained therein, all of which terms and provisions the Holders consent to by acceptance of their book-entry interests in the Global Warrant Certificate. Copies of the Warrant Agreement are on file at the Corporation’s headquarters. In the event of any conflict or inconsistency between this Global Warrant Certificate and the Warrant Agreement, this Global Warrant Certificate shall control. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Warrant Agreement dated as of _________, 2011 by and between the Corporation and Continental Stock Transfer & Trust Company (as such agreement may be amended from time to time, the “Warrant Agreement”).

1. Exercise Period. The Warrants shall vest in full and become exercisable on _________, 2011 (the “Vesting Date”) and, notwithstanding anything to the contrary contained herein, shall expire at 5:00 p.m. (Eastern Time) on ___________, 2018 (the “Termination Date”).

-14-

2. Exercise of Warrants. Each Holder may, at any time on or after the Vesting Date and prior to the Termination Date, exercise his, her or its Warrant in whole or in part at an exercise price per share equal to $1.466 per share, subject to adjustment as provided herein (the “Exercise Price”), by the delivery of the Warrant Exercise Form annexed hereto duly completed and executed to the Warrant Agent at the Warrant Agent Office or at such other agency or office of the Corporation in the United States of America as the Corporation may designate by notice in writing to the Holder at the address of such Holder appearing on the books of the Corporation, and by payment to the Corporation of the Exercise Price in lawful money of the United States by certified check or wire transfer for each share of Common Stock being purchased. Upon any partial exercise of a Warrant, the Warrant Agent shall make an appropriate adjustment to the account of the Holder to reflect a number of warrants for the account of the Holder equal (without giving effect to any adjustment thereof) to the number of shares called for by such Holder’s Warrants prior to such exercise, minus the number of shares designated by the Holder upon such exercise. In the event of the exercise of the rights represented by any Warrant, a certificate or certificates for the Warrant Shares so purchased, as applicable, registered in the name of the Holder, shall be delivered to the Holder hereof as soon as practicable after the rights represented by such Warrant shall have been so exercised.

3. Reservation of Warrant Shares. The Corporation agrees that, prior to the expiration of this Warrant, it will at all times have authorized and in reserve, and will keep available, solely for issuance or delivery upon the exercise of all outstanding Warrants represented by this Global Warrant Certificate, the number of Warrant Shares as from time to time shall be issuable by the Corporation upon the exercise of this Warrant.

4. No Stockholder Rights; No Rights to Net Cash Settled. No Warrant shall entitle the holder hereof to any voting rights or other rights as a stockholder of the Corporation. In no event may any Warrant be net cash settled.

5. Transferability of Warrant and Underlying Shares. Prior to the Termination Date and subject to compliance with applicable Federal and State securities and other laws, this Warrant and all rights hereunder are transferable, in whole or in part, at the office or agency of the Corporation by the Holder in person or by duly authorized attorney in accordance with the provisions of the Warrant Agreement and upon delivery of the Assignment Form annexed hereto properly endorsed for transfer. The Corporation or the Warrant Agent shall be entitled to require, as a condition of any such transfer, that the Holder and the transferee execute or provide such documents and make such representations and warranties as the Corporation or the Warrant Agent may deem appropriate to evidence compliance with applicable law or otherwise. None of the Warrant Shares, if issued, may be transferred by the Holder until after the date that is one year after the date of issuance of this Warrant.

6. Certain Adjustments. With respect to any rights that any Holder has to exercise any Warrant and convert into shares of Common Stock, Holder shall be entitled to the following adjustments:

-15-

(a) Merger or Consolidation. If at any time there shall be a merger or a consolidation of the Corporation with or into another entity when the Corporation is not the surviving corporation, then, as part of such merger or consolidation, lawful provision shall be made so that the holder hereof shall thereafter be entitled to receive upon exercise of each Warrant, during the period specified herein and upon payment of the aggregate Exercise Price then in effect, the number of shares of stock or other securities or property (including cash) of the successor corporation resulting from such merger or consolidation, to which the holder hereof as the holder of the stock deliverable upon exercise of each Warrant would have been entitled in such merger or consolidation if each Warrant had been exercised immediately before such transaction. In any such case, appropriate adjustment shall be made in the application of the provisions of each Warrant with respect to the rights and interests of the holder hereof as the holder of each Warrant after the merger or consolidation.

(b) Reclassification, Recapitalization, etc. If the Corporation at any time shall, by subdivision, combination or reclassification of securities, recapitalization, automatic conversion, or other similar event affecting the number or character of outstanding shares of Common Stock, or otherwise, change any of the securities as to which purchase rights under each Warrant exist into the same or a different number of securities of any other class or classes, each Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under each Warrant immediately prior to such subdivision, combination, reclassification or other change.

(c) Split or Combination of Common Stock and Stock Dividend. In case the Corporation shall at any time subdivide, redivide, recapitalize, split (forward) or change its outstanding shares of Common Stock into a greater number of shares or declare a dividend upon its Common Stock payable solely in shares of Common Stock, the Exercise Price shall be proportionately reduced and the number of Warrant Shares proportionately increased. Conversely, in case of a reverse stock split or the outstanding shares of Common Stock of the Corporation shall be combined into a smaller number of shares, the Exercise Price shall be proportionately increased and the number of Warrant Shares proportionately reduced.

7. Compliance with Securities Laws; Legend and Stop Transfer Orders. Unless the Warrant Shares are subject to an effective registration statement under the Securities Act, upon exercise of any part of any Warrant represented hereby, (i) the Corporation shall be entitled to require that the Holder make such representations and warranties as may be reasonably required by the Corporation to assure that the issuance of Warrant Shares is exempt from the registration requirements of applicable securities laws and (ii) the Corporation shall instruct its transfer agent to enter stop transfer orders with respect to such Warrant Shares, and all certificates or instruments representing the Warrant Shares shall bear on the face thereof substantially the following legend:

-16-

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED, OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

8. Redemption of Warrant. Each Warrant is subject to redemption by the Corporation as provided in this Section 8.

(a) Each Warrant may be redeemed, at the option of the Corporation, in whole and not in part, at a redemption price of $.0001 per Warrant (the “Redemption Price”), provided the average closing price of the Common Stock as quoted by Bloomberg, LP., or the Principal Trading Market (as defined below) on which the Common Stock is included for quotation or trading, shall equal or exceed $____ per share (taking into account all adjustments) for twenty (20) out of thirty (30) consecutive trading days.

(b) If the conditions set forth in Section 8(a) are met, and the Corporation desires to exercise its right to redeem each Warrant, it shall mail a notice (the “Redemption Notice”) to the registered holder of each Warrant by first class mail, postage prepaid, at least fourteen (14) business days prior to the date fixed by the Corporation for redemption of the Warrants (the “Redemption Date”).

(c ) The Redemption Notice shall specify (i) the Redemption Price, (ii) the Redemption Date, (iii) the redemption price payable, and (iv) that the right to exercise each Warrant shall terminate at 5:00 p.m. (New York time) on the business day immediately preceding the Redemption Date. No failure to mail such notice nor any defect therein or in the mailing thereof shall affect the validity of the proceedings for such redemption except as to a holder (a) to whom notice was not mailed, or (b) whose notice was defective. An affidavit of the Secretary or an Assistant Secretary of the Corporation that the Redemption Notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(d) Any right to exercise a Warrant shall terminate at 5:00 p.m. (New York time) on the business day immediately preceding the Redemption Date. On and after the Redemption Date, the holder of each Warrant shall have no further rights except to receive the Redemption Price.

(e) From and after the Redemption Date, the Corporation shall, at the place specified in the Redemption Notice, upon presentation and surrender to the Corporation by or on behalf of the holder thereof the warrant certificates evidencing each Warrant being redeemed, deliver, or cause to be delivered to or upon the written order of such holder, a sum in cash equal to the Redemption Price of each Warrant. From and after the Redemption Date, each Warrant shall expire and become void and all rights hereunder, except the right to receive payment of the Redemption Price, shall cease.

Re: NeoStem Agreement and Plan of Merger

Dear Ladies and Gentlemen:

We have acted as legal counsel to Amorcyte, Inc., a Delaware corporation (the “Company”) in connection with the execution and delivery of the Agreement and Plan of Merger by and among the Company, NeoStem, Inc. (“NeoStem”), AMO Acquisition Company I, Inc., and AMO Acquisition Company II, LLC (the “Agreement”). This opinion is being delivered to the parent pursuant to Article 7.2(e) of the Agreement. All capitalized terms used herein, but not otherwise defined herein, shall have the meanings ascribed to them in the Agreement.

In rendering the following opinions, we have made such inquiries and examined such documents as we have considered necessary or appropriate for the purpose of rendering the opinions herein set forth. As to various questions of fact material to this opinion, we have relied, without independent verification, upon representations and warranties of the Company contained in the Agreement and upon public records. We have not undertaken any special or independent examination or investigation to determine the existence of, or absence of, facts or circumstances not otherwise expressly disclosed to us, and no inference as to our knowledge of the existence of, or absence of, such facts or circumstances should be drawn merely from our representation of the Company. In our examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity and completeness of all documents submitted to us as originals, the conformity to original documents of documents submitted to us as copies and the authenticity of the originals of such documents. Further, in rendering the following opinion, we note that we have not conducted a docket search in any jurisdiction with respect to litigation that may be pending against the Company or any of its officers or directors. However, to our knowledge, except as disclosed in the disclosure schedules to the Agreement, we know of no facts or circumstances that are contrary to the opinions expressed herein.

Based upon such examination and in reliance thereon and having regard for legal considerations which we deem relevant, subject to the assumptions set forth herein and the limitations and qualifications set forth herein, we are of the following opinions:

The opinion of counsel to Amorcyte, Inc. (the “Company”) shall be to the effect that:

1. The Company is a Delaware corporation, duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company is duly qualified and in good standing to do business as a foreign corporation in the State of New Jersey.

2. The Company has the requisite power and authority to own its assets and conduct its business as presently conducted and to execute, deliver and perform its obligations under the Merger Agreement and the Escrow Agreement, and to consummate the transactions contemplated thereby.

3. The Company’s board of directors and stockholders have taken all action necessary for the authorization, execution and delivery of the Merger Agreement and the Escrow Agreement by the Company and the performance by the Company of its obligations under the Merger Agreement and the Escrow Agreement.

4. The Merger Agreement and the Escrow Agreement have been duly authorized, executed and delivered by the Company and such agreements constitute valid and binding obligations of the Company enforceable against it in accordance with their terms.

5. The execution and delivery of the Merger Agreement and Escrow Agreement and the Company's performance of its obligations thereunder do not and will not (i) contravene any provision contained in the Certificate of Incorporation of the Company, as amended or amended and restated as of the date hereof, the bylaws of the Company, as amended or amended and restated as of the date hereof, or other organizational documents of the Company, (ii) violate the provisions of any law, rule or regulation applicable to the Company; (iii) to our knowledge violate or result in a breach (with or without the lapse of time, the giving of notice or both) of or constitute a default under any Material Contract known to us, (iv) to our knowledge violate any judgment, decree, order or award of any government entity naming the Company, (v) to our knowledge result in the creation or imposition of any lien, claim, charge, encumbrance, equity, restriction or right on any of the assets or properties of the Company or any Person in the Amorcyte Group, or (vi) result in the acceleration of, or permit any Person to accelerate or declare due and payable prior to its stated maturity, any Liability known to us of the Company or any Person in the Amorcyte Group (except where the result of such acceleration would not cause a Material Adverse Effect).

6. The authorized capital stock of the Company consists of: (i) 31,000 shares of Amorcyte Common Stock, of which 7,821.5 shares are issued and outstanding and (ii) 11,000 shares of Amorcyte Series A Preferred Stock, of which [ ] shares are issued and outstanding. The Company has issued (i) Warrants to purchase an aggregate of 0 shares of Amorcyte Common Stock, all of which Warrants are issued and outstanding and (ii) Options to purchase an aggregate of 3,972 shares Amorcyte Common Stock, all of which Options are issued and outstanding. All of the securities which are issued and outstanding on the date hereof have been duly authorized and validly issued, are fully paid and non-assessable and were not issued in violation of any preemptive or similar rights. None of the securities issued by the Company since January 1, 2007 were issued in violation of any registration requirements under federal securities laws. Immediately prior to the First Effective Time, the Company validly modified in accordance with their terms and the terms of the Merger Agreement, and without liability to the Company, all outstanding Warrants and Options. Immediately prior to the First Effective Time, the Company validly cancelled in accordance with their terms and without liability to the Company all outstanding other rights, agreements, or commitments known to us or listed in the schedules to the Merger Agreement to which the Company or any Amorcyte Securityholder is a party or by which any such party is bound obligating the Company or the Amorcyte Securityholder to grant, issue, or sell any capital stock or any other security in the Company.

7. Except for the filing of the Certificate of Merger with the Secretary of State of the State of Delaware, no consent, approval or authorization of or designation, declaration, filing with any Governmental Authority or other action on the part of the Company is required in connection with the consummation of the transactions contemplated by the Merger Agreement and the Escrow Agreement.

8. Assuming that all necessary action in respect of the First Merger has been duly taken by the Parent and Subco, upon the filing of the First Certificate of Merger in the office of the Secretary of State of the State of Delaware (and the acceptance of such filings by such offices) and the payment of all applicable filing fees with respect thereto, the First Merger will be effective at the First Effective Time under the DGCL.

9. To our knowledge, except as disclosed in the disclosure schedules to the Agreement, there are no civil, criminal or administrative actions, suits or proceedings which are pending or have been threatened in writing against the Company or any Person in the Amorcyte Group which (a) seek either damages in excess of $25,000 or equitable relief or (b) in any manner challenge or seek to prevent, enjoin, alter or delay the transactions contemplated by the Merger Agreement.

We express no opinion herein as to laws other than the laws of the State of Delaware and the federal law of the United States of America. All opinions are rendered as of the date of this opinion unless otherwise expressly indicated.

The opinions expressed herein are subject to the following qualifications, limitations, and assumptions:

(a) No opinion is given, either express or implied, as to any document, agreement, instrument or certificate delivered or to be delivered in connection with the Agreement other than the documents attached as schedules or exhibits to the Agreement and, with respect to those schedules or documents, only as expressly set forth and qualified and limited herein.

(b) No opinion is given with respect to the effect of rules of law governing specific performance, injunctive relief and other equitable remedies.

(d) No opinion is given with respect to the following miscellaneous provisions in the Agreement, the exhibits or schedules thereto: notice requirements, merger provisions, and choice of law and whether provisions for waiver or modification may be limited by general contract principles and rules of construction.

(e) No opinion is given with respect to the enforceability of provisions that may purport to restrict access to legal or equitable remedies or provisions that may purport to impose liquidated damages, penalties, set-offs or forfeitures.

(f) We express no opinion as to whether a Court in any jurisdiction will find that any provisions relating to a covenant not to compete contained in the Agreement the exhibits or schedules thereto are valid or enforceable.

(g) No opinion is given, either express or implied, with respect to any requirement that provisions of the Agreement, the exhibits or schedules thereto, may only be waived in writing, to the extent an oral agreement has been consummated modifying provisions of the Agreement, the exhibits or schedules thereto, and other schedules or documents.

(h) No opinion is given, either express or implied, with respect to the effect of judicial decisions that may permit the introduction of extrinsic evidence to modify the terms or the interpretation of the Agreement the exhibits or schedules thereto.

(i) No opinion is given, either express or implied, with respect to the enforceability of provisions of the Agreement, the exhibits or schedules thereto, that purport to establish evidentiary standards or to make determinations conclusive.

(j) No opinion is given, either express or implied, with respect to the enforceability of provisions of the Agreement, the exhibits or schedules thereto, that purport to establish particular courts as the forum for the adjudication of any controversy relating to the Agreement, and other schedules or documents.

(k) No opinion is given, either express or implied, with respect to the enforceability of provisions of the Agreement, the exhibits or schedules thereto, providing that rights or remedies are not exclusive, that every right or remedy is cumulative, or that the election of a particular remedy or remedies does not preclude recourse to one or more other remedies.

(l) No opinion is given with respect to the enforceability of any provision of the Agreement that would result in the forfeiture of any rights of any Amorcyte Securityholder if such Amorcyte Securityholder does not deliver an executed Letter of Transmittal within certain time periods set forth in the Agreement.

(m) No opinion is given as to the effect of bankruptcy, insolvency, reorganization, arrangement, fraudulent transfer, moratorium, or similar laws relating to or affecting the rights of creditors.

(n) No opinion is given as to federal laws and judicial decisions concerning the enforceability of contractual provisions which were unconscionable at the time the contract was made.

(o) With respect to the opinion expressed in paragraph 1 above, as it relates to the good standing of the Company, we have relied solely upon a Certificate of Good Standing issued by the Secretary of State of Delaware dated [____________________].

(p) The words “to our knowledge” or the like used in this letter refer only to items of which we have current actual knowledge. The words “our knowledge” or the like used in this letter signify that, in the course of our representation of the Company, no information has come to our attention that would give us current actual knowledge that any statements, opinions or other matters so qualified are not accurate.

Further, the words “our knowledge”, “to our knowledge” or the like as used in this letter are intended to be limited to the actual knowledge of the attorneys within our firm who have been directly involved in representing the Company.

The opinions contained herein address only the facts in existence and the laws in effect on the date hereof and we have no obligation to update our opinions for changes in such laws or other events occurring after the date hereof. Without our written consent and except as may be required by applicable law: (i) no person other than NeoStem, Subco, and Subco II, their successors and assigns and the affiliates may rely on this letter for any purpose; (ii) this letter may not be cited or quoted in any financial statement, prospectus, private placement memorandum, or other similar document; (iii) this letter may not be cited or quoted in any other document or communication which might encourage reliance upon this letter by any person or for any purpose excluded by the restrictions in this paragraph; and (iv) copies of this letter may not be furnished to anyone for purposes of encouraging such reliance.
