Item 8.01. Other Events.

     On July 18, 2008, the Securities and Exchange Commission (the “Commission”) declared effective the Registration Statement on Form S-3 (File No. 333-151891) of StemCells, Inc. (the “Company”) filed on June 24, 2008 with the Commission (the “Registration Statement”). The Registration Statement permits the Company to issue, in one or more offerings, shares of common stock, preferred stock, warrants or debt securities at an aggregate initial offering price not to exceed $100,000,000.

     On October 28, 2009, the Company entered into a placement agency agreement with Chardan Capital Markets, LLC as the exclusive placement agent, relating to the sale and issuance by the Company to certain investors (the “Purchasers”) of up to 10,000,000 shares of the Company’s common stock, par value $0.01 per share (“Common Stock”) and warrants (“Warrants”) to purchase up to 4,000,000 shares of Common Stock, in the aggregate, pursuant to the terms of the placement agency agreement and the related subscription agreements. The Common Stock and Warrants will be sold in units (the “Units”), with each Unit consisting of (i) one share of the Company’s Common Stock and (ii) a warrant to purchase 0.4 of a share of Common Stock, at a purchase price of $1.25 per Unit, pursuant to the Registration Statement (the “Offering”). The Warrants will generally be exercisable for a period of five years beginning six months after the date of issuance, and will carry a price per share equal to $1.50, or 106% of the closing price of the Common Stock on October 27, 2009 as reported by NASDAQ.

     The Company anticipates raising gross proceeds of $12.5 million. The net offering proceeds to the Company from the sale of the Units, after deducting the placement agent fees and other estimated offering expenses payable by the Company, are expected to be approximately $11.9 million.

In addition, together with each Share sold, the Company shall issue and sell to each Investor a warrant substantially in the form the warrant attached as Annex I to Exhibit A hereto to purchase 0.40 shares of the Company’s Common Stock per each share issued to such Investor (the “Warrants”). The Shares and the Warrants are collectively referred to herein as the “Securities.” The Company desires to engage Chardan Capital Markets, LLC (“Chardan”) as the exclusive placement agent (the “Placement Agent”) in connection with such issuance and sale. The Securities are described in the Prospectus which is referred to below.

          The Company has prepared and filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-151891) under the Act (the “registration statement”). Amendments to such registration statement, if necessary or appropriate, have been similarly prepared and filed with the Commission in accordance with the Act. Such registration statement, as so amended, has become effective under the Act.

          Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Placement Agent (the “Effective Time”), including (i) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (ii) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the Effective Time, and (iii) any registration statement filed to register the offer and sale of Securities pursuant to Rule 462(b) under the Act.

          Except where the context otherwise requires, “Prospectus Supplement,” as used herein, means the final prospectus supplement, relating to the Securities, filed by the Company with the Commission pursuant to Rule 424(b) under the Act on or before the second business day after the date hereof (or such earlier time as may be required under the Act), in the form

          Any reference herein to the registration statement, the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”) on or after the initial effective date of the Registration Statement, or the date of the Basic Prospectus, the Prospectus Supplement, the Prospectus or such Permitted Free Writing Prospectus, as the case may be, and deemed to be incorporated therein by reference.

As compensation for services rendered, at the time of purchase (as defined below) the Company shall pay to the Placement Agent an amount equal to 4.0% of the

The Shares are being sold to Investors at a price of $1.25 per share, and together with each Share, Investors will receive a Warrant to purchase 0.40 shares of the Company’s Common Stock at an exercise price of $1.50 per share. The Placement Agent may retain other brokers or dealers to act as sub-agents on its behalf in connection with the offering and sale of the Securities.

          The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable efforts basis, and this Agreement shall not give rise to any commitment by the Placement Agent or any of its affiliates to underwrite or purchase any of the Securities or otherwise provide any financing.

The sale of the Securities shall be made pursuant to purchase agreements substantially in the form included as Exhibit A hereto (the “Subscription Agreements”).

     2. Payment and Delivery. Subject to the terms and conditions hereof, payment of the purchase price for, and delivery of certificates for, the Securities shall be made at the office of Chardan Capital Markets, LLC at 17 State Street, Suite 1600, New York, New York 10004 (or at such other place as shall be agreed upon by you and the Company), at 10:00 A.M., New York City time, on November 2, 2009 (unless another time shall be agreed to by you and the Company).

          If the Placement Agent elects to terminate this Agreement as provided in this Section 7, the Company shall be notified promptly in writing.

          If the sale of the Securities, as contemplated by this Agreement and the Subscription Agreements, is not carried out for any reason permitted under this Agreement or the Subscription Agreements, or if such sale is not carried out because the Company shall be unable to comply with any of the terms of this Agreement or the Subscription Agreements, the Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(m), 5 and 8 hereof), and the Placement Agent shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 8 hereof).

     8. Indemnity and Contribution.

     (a) The Company agrees (i) to indemnify, defend and hold harmless the Placement Agent, their respective, directors, officers, employees and agents, and each person, if any, who controls the Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (or actions in respect thereof as contemplated below) which the Placement Agent or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or actions in respect thereof as contemplated below) arises out of or is based (A) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein, (B) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law, (C) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430B or Rule 430C under the Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, (D) upon any untrue statement or alleged untrue statement of a material fact contained in the Basic Prospectus (as amended or supplemented), any Permitted Free Writing Prospectus, the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a

material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (E) in whole or in part upon any act or failure to act or alleged act or failure to act by the Placement Agent in reliance upon (A), (B), (C) or (D), and in connection with or relating in any manner to the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (A), (B), (C) or (D) above, provided that the Company shall not be liable under this clause (E) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted primarily from any such acts or failures to act undertaken or omitted to be taken by such Placement Agent through its bad faith or willful misconduct; and (ii) to reimburse each Placement Agent, its respective officers, directors, employees, agents and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Placement Agent) as such expenses are reasonably incurred by the Placement Agent, or its respective officers, directors, employees and agents or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use in the Registration Statement, any Permitted Free Writing Prospectus, or the Prospectus (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

     (b) The Placement Agent agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company or any such director, officer or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Permitted Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Permitted Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use therein; and to reimburse the Company or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby

acknowledges that the only information that the Placement Agent has furnished to the Company expressly for use in the Registration Statement, any Permitted Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth in Section 9.

     (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party a) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and b) will not, in any event, relieve the indemnifying party from any liability other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

     (d) The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to

indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

     (e) If the indemnification provided for in Section 8(a) or (b), as applicable, is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Placement Agent, on the other hand, from the placement of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Placement Agent, on the other hand, in connection with the statements or omissions contained in the Registration Statement, the Basic Prospectus (as amended or supplemented), any Permitted Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Placement Agent, on the other hand, in connection with the placement of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the placement of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total compensation received by the Placement Agent bears to the aggregate proceeds from the placement of the Securities. The relative fault of the Company, on the one hand, and the Placement Agent, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact or any such inaccurate or alleged inaccurate representation or warranty relates to information supplied by the Company, on the one hand, or the Placement Agent, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 8(e).

     (f) Notwithstanding the provisions of Section 8(e), the Placement Agent shall not be required to contribute any amount in excess of the compensation received by the Placement Agent in connection with the placement contemplated by this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Placement Agent’s obligations to contribute pursuant to Section 8(e) is in proportion to itsrespective percentage allocations of the compensation payable by the Company pursuant to Section 1 hereof. For purposes of Section 8(e), each director, officer, employee and agent of the Placement Agent and each person, if any, who controls the Placement Agent within the meaning of the Act or the Exchange Act shall have the same rights to contribution as the Placement Agent, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act or the Exchange Act shall have the same rights to contribution as the Company.

     9. Information Furnished by the Placement Agent. The statements set forth under the caption “Plan of distribution—Price stabilization” in the Prospectus Supplement, only insofar as such statements relate to the stabilization activities that may be undertaken by the Placement Agent, constitute the only information furnished by the Placement Agent, as such information is referred to in Sections 3 and 8 hereof.

     12. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the

Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Company consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against the Placement Agent or any indemnified party. The Placement Agent and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waive all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

     13. Parties at Interest. Except as set forth in the Subscription Agreement, the Agreement herein set forth has been and is made solely for the benefit of the Placement Agent and the Company and to the extent provided in Section 8 hereof the controlling persons, partners, directors and officers referred to in such Section 8, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from the Company) shall acquire or have any right under or by virtue of this Agreement.

The Company hereby acknowledges that the Placement Agent is acting solely as a Placement Agent in connection with the purchase and sale of the Company’s securities. The Company further acknowledges that the Placement Agent is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Placement Agent act or be responsible as a fiduciary to the Company, its management, stockholders or creditors or any other person in connection with any activity that the Placement Agent may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Placement Agent hereby expressly disclaims any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Placement Agent agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by a Placement Agent to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

     15. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

To Purchase 2,000,000 Shares of Common Stock

Date of Issuance: October 28, 2009

VOID AFTER APRIL 28, 2015

     THIS CERTIFIES THAT, for value received,                      , or permitted registered assigns (the “Holder”), is entitled to subscribe for and purchase at the Exercise Price (defined below) from StemCells, Inc., a Delaware corporation (the “Company”), up to 2,000,000 shares of the common stock of the Company, par value $0.01 per share (the “Common Stock”). This warrant is one of a series of warrants issued by the Company as of the date hereof (individually a “Warrant”; collectively, “Company Warrants”) pursuant to that certain subscription agreement between the Company and the Holder, dated as of October 28, 2009 (the “Subscription Agreement”).

     1. DEFINITIONS. Capitalized terms used herein but not otherwise defined herein shall have their respective meanings as set forth in the Subscription Agreement. As used herein, the following terms shall have the following respective meanings:

     (a) “Exercise Period” shall mean the period commencing with the date occurring six months after the date hereof and ending five years and six months from the date hereof, unless sooner terminated as provided below.

     (b) “Exercise Price” shall mean $1.50 per share, subject to adjustment pursuant to Section 4 below.

     (c) “Exercise Shares” shall mean the shares of Common Stock issuable upon exercise of this Warrant.

     (d) “Trading Day” shall mean (i) any day on which the Common Stock is listed or quoted and traded on its primary Trading Market, (ii) if the Common Stock is not then listed or quoted and traded on any eligible market (meaning any of the NYSE, AMEX or NASDAQ), then a day on which trading occurs on the OTC Bulletin Board (or any successor thereto), or (iii) if trading does not occur on the OTC Bulletin Board (or any successor thereto), any business day.

     2. EXERCISE OF WARRANT.

     2.1 STANDARD EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the

following to the Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to the Holder):

     (a) An executed Notice of Exercise in the form attached hereto; and

     (b) Payment of the Exercise Price either (i) in cash or by check (subject to the limitations in Section 2.4 below), or (ii) pursuant to net exercise terms outlined under Section 2.2 below.

     The Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Exercise Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Exercise Shares available hereunder shall have the effect of lowering the outstanding number of Exercise Shares purchasable hereunder in an amount equal to the applicable number of Exercise Shares purchased. The Holder and the Company shall maintain records showing the number of Exercise Shares purchased and the date of such purchases.

     Certificates for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposits and Withdrawal at Custodian (DWAC) system if the Company is a participant in such system, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within three Trading Days from the delivery to the Company of the Notice of Exercise, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above. This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. The Exercise Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date this Warrant has been exercised by payment to the Company of the Exercise Price.

     If by the close of the fifth Trading Day after delivery of an Notice of Exercise, the Company fails to deliver to the Holder a certificate representing the required number of Exercise Shares in the manner required pursuant to this Section 2, and such failure to deliver the Exercise Shares is caused by the Company’s failure to use commercially reasonable efforts to comply with this Section 2 and/or the covenants in Section 3.1 herein, and if after such fifth Trading Day and prior to the receipt of such Exercise Shares, the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Exercise Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall, within three Trading Days after the Holder’s request and in the Holder’s sole discretion, either (1) pay in cash to the Holder an amount equal to the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Exercise Shares) shall terminate or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Exercise Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Exercise Shares, times (B) the closing bid price on the date of exercise.

     The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

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

     2.2 NET EXERCISE. If during the Exercise Period, the issuance of the Exercise Shares to the Holder is not covered by the Registration Statement, as defined in the Subscription Agreement, or any other effective registration statement under the Securities Act of 1933, as amended, and the fair market value of one share of the Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), the Holder shall be permitted to exercise this Warrant by electing to receive (and the Company shall be permitted satisfy its obligation to issue the shares to be issued on exercise of this Warrant by issuing to the Holder) shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled), in lieu of paying the Exercise Price in immediately available funds. Upon delivery of a properly endorsed Notice of Exercise, the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y (A–B)
         A    

Where X =		the number of shares of Common Stock to be issued to the Holder
Y =		the number of shares of Common Stock for which the Warrant is then being exercised

A =		the fair market value of one share of the Company’s Common Stock (at the date of such calculation)
B =		Exercise Price in effect at the time of exercise

     For purposes of the above calculation, the “fair market value” of one share of Common Stock shall mean (i) the average of the closing sales prices for the shares of Common Stock on the NASDAQ Global Market or other trading market where such security is listed or traded as reported by Bloomberg Financial Markets (or a comparable reporting service of national reputation selected by the Company and reasonably acceptable to the Holder if Bloomberg Financial Markets is not then reporting sales prices of such security) (collectively, “Bloomberg”) for the ten (10) consecutive trading days immediately preceding such date, or (ii) if the NASDAQ Global Market is not the principal trading market for the shares of Common Stock, the average of the reported sales prices reported by Bloomberg on the principal trading market for the Common Stock during the same period, or, if there is no sales price for such period, the last sales price reported by Bloomberg for such period, or (iii) if neither of the foregoing applies, the last sales price of such security in the over-the-counter market on the pink sheets or bulletin board for such security as reported by Bloomberg, or if no sales price is so reported for such security, the last bid price of such security as reported by Bloomberg or (iv) if fair market value cannot be calculated as of such date on any of the foregoing bases, the fair market value shall be as determined by the Board of Directors of the Company in the exercise of its good faith judgment.

     2.3 ISSUANCE OF NEW WARRANTS. Upon any partial exercise of this Warrant, the Company, at its expense, will forthwith and, in any event within five Trading Days, issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, exercisable, in the aggregate, for the balance of the number of shares of Common Stock remaining available for purchase under this Warrant.

     2.4 EXERCISE LIMITATIONS; HOLDER’S RESTRICTIONS. A Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise, such Holder (together with such Holder’s affiliates) would beneficially own in excess of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such issuance. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by such Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other shares of Common Stock or Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2.4, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act, it being acknowledged by a Holder that the Company is not representing to such Holder that such calculation is in compliance with

Section 13(d) of the Exchange Act and such Holder is solely responsible for any schedules or other filings required to be filed under the Exchange Act. To the extent that the limitation contained in this Section 2.4 applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which a portion of this Warrant is exercisable shall be in the sole discretion of a Holder, and the submission of a Notice of Exercise shall be deemed to be each Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall be entitled to rely on the Holder’s determination and shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section 2.4, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company’s Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by such Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The provisions of this Section 2.4 may be waived by such Holder, at the election of such Holder, upon not less than 61 days’ prior notice to the Company, and the provisions of this Section 2.4 shall continue to apply until such 61st day (or such later date, as determined by such Holder, as may be specified in such notice of waiver).

     3. COVENANTS OF THE COMPANY.

     3.1 COVENANTS AS TO EXERCISE SHARES. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof.

     The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

     3.2 NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, and will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to

protect the exercise rights of the Holder against impairment.

     3.3 NOTICES OF RECORD DATE AND CERTAIN OTHER EVENTS. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall provide to the Holder, at least ten (10) days prior to the date on which any such record is to be taken for the purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall provide to the Holder, at least ten (10) days prior to the date of the occurrence of any such event, a notice specifying such date. In the event the Company authorizes or approves, enters into any agreement contemplating, or solicits stockholder approval for any Fundamental Transaction, as defined in Section 6 herein, the Company shall provide to the Holder, at least ten (10) days prior to the date of the occurrence of such Fundamental Transaction, a notice specifying such date. Notwithstanding the foregoing, the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

     4. ADJUSTMENT OF EXERCISE PRICE AND EXERCISE SHARES.

     (a) If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant.

     (b) If the Company, at any time while this Warrant is outstanding, distributes to holders of Common Stock, (i) Common Stock or any shares of stock or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution (other than a dividend or distribution covered in Section 4(a) above); (ii) any cash paid or payable otherwise than as a cash dividend; or (iii) any other asset, then and in each such case, the Holder hereof will, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property (including cash in the cases referred to in clauses (ii) and (iii) above) which such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property.

     (c) Upon the occurrence of each adjustment pursuant to this Section 4, the Company at its expense will, at the written request of the Holder, promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Exercise Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

     5. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction.

     6. FUNDAMENTAL TRANSACTIONS. If, at any time while this Warrant is outstanding, (i) the Company effects any merger or consolidation of the Company with or into another entity, in which the shareholders of the Company as of immediately prior to the transaction own less than a majority of the outstanding stock of the surviving entity, (ii) any tender offer or exchange offer (whether by the Company or another person or entity) is completed pursuant to which the holders of more than the 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the person or persons making or party to, or associated or affiliated with the Persons making or party to, such purchase, tender or exchange offer) are permitted to tender or exchange their shares for other securities, cash or property, or (iii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, or (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 4 above), (v) the Company consummates a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another person whereby such other person acquires more than the 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other person or other persons making or party to, or associated or affiliated with the other persons making or party to, such stock purchase agreement or other business combination), or (vi) any “person” or “group” (as these terms are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the “beneficial owner” (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended), directly or indirectly, of 50% of the aggregate ordinary voting power represented by issued and outstanding Common Stock (each, a “Fundamental Transaction”), the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if

it had been, immediately prior to such Fundamental Transaction, the holder of the number of Exercise Shares then issuable upon exercise in full of this Warrant (the “Alternate Consideration”). To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant into Alternate Consideration. In lieu of the Alternate Consideration, the Holder shall have the right to require the Company to redeem this Warrant, for a purchase price, payable in cash on the closing date of such Fundamental Transaction, equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the closing date of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg determined as of the day immediately following the public announcement of the applicable Fundamental Transaction and reflecting (i) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of such date, (ii) an expected volatility equal to the lesser of (x) 60-day volatility or (y) 100-day volatility, in each case obtained from the HVT function on Bloomberg, provided however, the expected volatility used to calculate such value shall not exceed eighty (80%) percent and (iii) an underlying price per share used in such calculation equal to the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in the Fundamental Transaction. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 6 and ensuring that this Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

     7. NO STOCKHOLDER RIGHTS. Other than as provided in Section 3.3 or otherwise herein, the Holder, solely in such Holder’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Holder’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Exercise Shares which such Holder is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

     8. TRANSFER OF WARRANT. Subject to compliance with any applicable laws, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 2.3), registered as the Holder may request, representing the right to purchase the number of Exercise Shares being transferred

by the Holder and, if less then the total number of Exercise Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 2.3) to the Holder representing the right to purchase the number of Exercise Shares not being transferred.

     9. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to reasonable bond and indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

     10. DISPUTE. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Exercise Shares, the Company shall promptly issue to the Holder the number of Exercise Shares that are not disputed and resolve such dispute in accordance with this Section 10. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Exercise Shares, the Company shall provide notice to the Holder of the disputed determinations or arithmetic calculations within two Trading Days of receipt of the Notice of Exercise giving rise to such dispute, as the case may be. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Exercise Shares within three Trading Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two Trading Days provide submit (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Exercise Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

     11. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next Trading Day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at the address listed on the signature page hereto and to Holder at the applicable address set forth on the applicable signature page to the Subscription Agreement or at such other address as the Company or Holder may designate by ten (10) days advance written notice to the other parties hereto.

     12. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

     13. GOVERNING LAW; WAIVER OF JURY TRIAL. This Warrant shall be governed by, and construed in accordance with, the laws of the State of New York. The Holder and the Company hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the

Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated thereby. The Holder and the Company irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Warrant in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND THE HOLDER HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY.

     14. AMENDMENT OR WAIVER. Any term of this Warrant may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) with the written consent of the Company and the Holder. The Company shall give prompt written notice to the Holder of any amendment hereof or waiver hereunder that was effected without the Holder’s written consent. No waivers of any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

Re:		Registration Statement on Form S-3 (Registration No. 333-151891), initially filed on June 24, 2008 with the Securities and Exchange Commission (the “Commission”) and declared effective on July 18, 2008.

Ladies and Gentlemen:

This opinion is furnished to you in connection with the above-referenced registration statement (the “Registration Statement”), the base prospectus dated July 18, 2008 (the “Base Prospectus”) and the preliminary prospectus supplement dated October 28, 2009 (together with the Base Prospectus, the “Prospectus”). The Prospectus relates to the offering by StemCells, Inc. (the “Company”) of (i) 10,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”) and (ii) warrants (the “Warrants”) to purchase 4,000,000 shares of the Common Stock (the “Warrant Shares”), which Shares, Warrants and Warrant Shares are covered by the Registration Statement. We understand that the Shares, Warrants and Warrant Shares are to be offered and sold in the manner described in the Prospectus.

We have acted as counsel for the Company in connection with the issuance of the Shares, Warrants and Warrant Shares. For purposes of this opinion, we have examined and relied upon such documents, records, certificates and other instruments as we have deemed necessary.

The opinions expressed below are limited to the Delaware General Corporation Law, including the applicable provisions of the Delaware Constitution and the reported cases interpreting those laws.

Based upon and subject to the foregoing, we are of the opinion that (i) the Shares, when sold as described in the Prospectus, will be duly authorized, validly issued, fully paid and non-assessable, (ii) provided that the Warrants have been duly executed and delivered by the Company and duly delivered to the purchasers thereof against payment therefor, then the Warrants, when issued and sold as described in the Prospectus, will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally and by general equitable principles (regardless of whether such enforceability is considered in a

At the Closing, the Company shall deliver to the Investor, using customary book-entry procedures, the number of Securities as set forth above in Section 2, and the Investor shall deliver, or cause to be delivered, to the Company by Federal Funds wire transfer the full amount of the Purchase Price for the Securities being purchased.

     5. This Subscription Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to the principles of conflicts of law.

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

     7. A prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, may be obtained, when available, from the Company at 3155 Porter Drive, Palo Alto, CA 94304, Attention: Chief Executive Officer.

     8. The Company confirms that it has entered into a Placement Agency Agreement (the “Placement Agency Agreement”) with Chardan Capital Markets, LLC (the “Placement Agent”) that contains certain representations, warranties, covenants and agreements of the Company that may be relied upon by the Investor, which shall be a third party beneficiary thereof. A copy of the Placement Agency Agreement is available upon request.

     9. The Company further confirms and the Investor acknowledges that the Investor’s obligation to purchase the Securities is subject to the condition that the Placement Agent shall not have (a) terminated the Placement Agency Agreement or (b) determined that the conditions to closing in the Placement Agency Agreement have not been satisfied.

The Offering Information may be provided to the Investor by any means permitted under the Act, including in the Prospectus Supplement (delivered to the Investor or made available to it by the filing of an electronic version thereof with the Commission), a free writing prospectus or oral communications.

     11. No offer by the Investor to buy Securities will be accepted and no part of the Purchase Price will be delivered to the Company until the Investor has received the Offering Information and the Company has accepted such offer by countersigning a copy of this Subscription Agreement, and any such offer may be withdrawn or revoked, without obligation or commitment of any kind, at any time prior to the Company (or the Placement Agent on behalf of the Company) sending (orally, in writing or by electronic mail) notice of its acceptance of such offer. This Subscription Agreement will constitute only an indication of interest and will involve no obligation or commitment of any kind until the Investor has been delivered the Offering Information and this Subscription Agreement is accepted and countersigned by or on behalf of the Company.
