STEMCELLS, INC. CALLABLE WARRANT Warrant No. CW-1 Dated: July 31, 2000 STEMCELLS, INC., a Delaware corporation (the "Company"), hereby certifies that, for value received, MILLENNIUM PARTNERS, L.P., or its registered assigns ("Holder"), is entitled, subject to the terms set forth below, to purchase from the Company a total of 101,587 shares of common stock, $.01 par value per share (the "Common Stock"), of the Company (each such share, a "Warrant Share" and all such shares, the "Warrant Shares") at an exercise price equal to $4.7250 per share (as adjusted from time to time as provided in Section 9, the "Exercise Price"), at any time and from time to time from and after the date hereof and through and including July 31, 2005 (the "Expiration Date"), and subject to the following terms and conditions: 1. REGISTRATION OF WARRANT. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the "Warrant Register"), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, and the Company shall not be affected by notice to the contrary. 2. REGISTRATION OF TRANSFERS AND EXCHANGES. (a) The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Transfer Agent or to the Company at the office specified in or pursuant to Section 3(b). Upon any such registration or transfer, a new warrant to purchase Common Stock, in substantially the form of this Warrant (any such new warrant, a "New Warrant"), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance of such transferee of all of the rights and obligations of a holder of a Warrant. (b) This Warrant is exchangeable, upon the surrender hereof by the Holder to the office of the Company specified in or pursuant to Section 3(b) for one or more New Warrants, evidencing in the aggregate the right to purchase the number of Warrant Shares which may then be purchased hereunder. Any such New Warrant will be dated the date of such exchange. 3. DURATION, EXERCISE AND REDEMPTION OF WARRANTS. (a) This Warrant shall be exercisable by the registered Holder on any business day before 5:00 P.M., New York City time, at any time and from time to time on or after the date hereof to and including the Expiration Date. At 5:00 P.M., New York City time on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value. (b) Subject to Sections 2(b), 5 and 10, upon surrender of this Warrant, with the Form of Election to Purchase attached hereto duly completed and signed, to the Company at its address for notice set forth in Section 13 and upon payment of the Exercise Price multiplied by the number of Warrant Shares that the Holder intends to purchase hereunder, in the manner provided hereunder, all as specified by the Holder in the Form of Election to Purchase, the Company shall promptly (but in no event later than 3 business days after the Date of Exercise (as defined herein)) issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate, a certificate for the Warrant Shares issuable upon such exercise, free of restrictive legends except (i) either in the event that a registration statement covering the resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective or the Warrant Shares are not freely transferable without volume restrictions pursuant to Rule 144(k) promulgated under the Securities Act of 1933, as amended (the "Securities Act"), or (ii) if this Warrant shall have been issued pursuant to a written agreement between the original Holder and the Company, as required by such agreement. Any person so designated by the Holder to receive Warrant Shares shall be deemed to have become holder of record of such Warrant Shares as of the Date of Exercise of this Warrant. A "Date of Exercise" means the date on which the Company shall have received (i) this Warrant (or any New Warrant, as applicable), with the Form of Election to Purchase attached hereto (or attached to such New Warrant) appropriately completed and duly signed, and (ii) payment of the Exercise Price for the number of Warrant Shares so indicated by the holder hereof to be purchased. (c) This Warrant shall be exercisable, either in its entirety or, from time to time, for a portion of the number of Warrant Shares. If less than all of the Warrant Shares which may be purchased under this Warrant are exercised at any time, the Company shall issue or cause to be issued, at its expense, a New Warrant evidencing the right to purchase the remaining number of Warrant Shares for which no exercise has been evidenced by this Warrant. 2 (d) In lieu of delivering physical certificates representing the Warrant Shares issuable upon conversion of this Warrant, provided the Company's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer ("FAST") program, upon request of the Holder, the Company shall use its best efforts to cause its transfer agent to electronically transmit the Warrant Shares issuable upon exercise to the Holder, by crediting the account of the Holder's prime broker with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system. The time periods for delivery described above shall apply to the electronic transmittals through the DWAC system. The Company agrees to coordinate with DTC to accomplish this objective. (e) Commencing at any time after the date of the issuance of this Warrant, the Company shall have the right, upon fifteen (15) days notice to the Holder, to cancel this Warrant in full effective on such 15th day (the "Cancellation Date"). The Holder may exercise this Warrant at any time prior to the Cancellation Date. On the Cancellation Date, the Company shall pay in full and complete satisfaction of its obligations under the remaining portion of this Warrant to the Holder an amount in cash equal to (i) the number of shares of Common Stock then issuable hereunder multiplied by (ii) $8.64, as such number shall be appropriately adjusted for stock splits, recapitalizations and similar events minus the applicable Exercise Price as of the Cancellation Date, and the Holder shall surrender this Warrant to the Company for cancellation. 4. REGISTRATION RIGHTS. This Warrant and the Holder hereof are entitled to the benefits of, and subject to the terms and condition of and obligations under, that certain Registration Rights Agreement dated the date hereof between the Company and the original Holder (the "Registration Rights Agreement"). 5. Intentionally left blank. 6. PAYMENT OF TAXES. The Company will pay all documentary stamp taxes attributable to the issuance of Warrant Shares upon the exercise of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof. 7. REPLACEMENT OF WARRANT. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and indemnity, if requested, satisfactory to it. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable charges as the Company may prescribe. 8. RESERVATION OF WARRANT SHARES. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant 3 as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares that shall be so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. 9. CERTAIN ADJUSTMENTS. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section. Upon each such adjustment of the Exercise Price pursuant to this Section, the Holder shall thereafter prior to the Expiration Date be entitled to purchase, at the Exercise Price resulting from such adjustment, the number of Warrant Shares obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment. (a) If the Company, at any time while this Warrant is outstanding, (i) shall pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or on any other class of capital stock payable in shares of Common Stock (except dividends or distributions paid on preferred or other senior stock), (ii) subdivide outstanding shares of Common Stock into a larger number of shares, or (iii) combine outstanding shares of Common Stock into a smaller number of shares, the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination, and shall apply to successive subdivisions and combinations. (b) In case of any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property, then the Holder shall have the right thereafter to exercise this Warrant only into the shares of stock and other securities and property receivable upon or deemed to be held by holders of Common Stock following such reclassification or share exchange, and the Holder shall be entitled upon such event to receive such amount of securities or property as such Holder would have been entitled to receive if such Holder had exercised this Warrant immediately prior to such reclassification or share exchange (net of the applicable Exercise Price). The terms of any such reclassification or share exchange shall include such terms so as to continue to give to the Holder the right to receive the securities or property set forth in this Section 9(b) upon any exercise following any such reclassification or share exchange. (c) If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to holders of this Warrant) evidences of its indebtedness or assets or rights or warrants to subscribe for or purchase any security 4 (excluding those referred to in Sections 9(a), (b) and (d)), then in each such case the Exercise Price shall be determined by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the Exercise Price determined as of the record date mentioned above, and of which the numerator shall be such Exercise Price on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock as determined by the Company's independent certified public accountants that regularly examine the financial statements of the Company (an "Appraiser"). (d) If at any time the Company or any subsidiary thereof, as applicable with respect to Common Stock Equivalents (as defined below), shall issue shares of Common Stock or rights, warrants, options or other securities or debt that is convertible into or exchangeable for shares of Common Stock ("COMMON STOCK EQUIVALENTS"), entitling any person or entity to acquire shares of Common Stock at a price per share less than the market price of the Common Stock at the time of issuance, except with respect to a Board Approved Transaction (as defined herein), forthwith upon such issue or sale, the Exercise Price shall be reduced to the price (calculated to the nearest cent) determined by multiplying the Exercise Price in effect immediately prior thereto by a fraction, the numerator of which shall be the sum of (i) the number of shares of Common Stock outstanding immediately prior to such issuance, and (ii) the number of shares of Common Stock which the aggregate consideration received (or to be received, assuming exercise or conversion in full of such Common Stock Equivalents) for the issuance of such additional shares of Common Stock would purchase at the Exercise Price, and the denominator of which shall be the sum of the number of shares of Common Stock outstanding immediately after the issuance of such additional shares. For purposes hereof, all shares of Common Stock that are issuable upon conversion, exercise or exchange of Common Stock Equivalents shall be deemed outstanding immediately after the issuance of such Common Stock Equivalents. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. However, upon the expiration of any Common Stock Equivalents the issuance of which resulted in an adjustment in the Exercise Price pursuant to this Section, the Exercise Price shall immediately upon such expiration be recomputed and effective immediately upon such expiration be increased to the price which it would have been (but reflecting any other adjustments in the Exercise Price made pursuant to the provisions of this Section after the issuance of such Common Stock Equivalents) had the adjustment of the Exercise Price made upon the issuance of such Common Stock Equivalents been made on the basis of offering for subscription or purchase only that number of shares of the Common Stock actually purchased upon the exercise of such Common Stock Equivalents actually exercised. Notwithstanding anything herein to the contrary, issuances of any stock or stock options under any bona fide employee benefit plan or compensation arrangement of the Company, shall not be subject to the provisions of this Section. A "Board Approved Transaction" is a transaction involving a strategic alliance, acquisition of stock or assets, merger, collaboration, joint venture, partnership or similar arrangement of the Company with another corporation, partnership or other business entity (A) which is engaged in a business similar complementary or related to the business of the Company or (B) pursuant to which the Company issues securities with the primary purpose to directly or indirectly acquire, license or otherwise become entitled to use technology relevant to or useful in 5 the Company's business, so long as the Company's Board of Directors by resolution duly adopted approves such transaction in accordance with its duties under applicable law. (e) In case of any (1) merger or consolidation of the Company with or into another Person, or (2) sale by the Company of more than one-half of the assets of the Company (on a market value basis) in one or a series of related transactions, or (3) tender or other offer or exchange (whether by the Company or another Person) pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, stock, cash or property of the Company or another Person; then the Holder shall have the right thereafter to (A) exercise this Warrant for the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Stock following such merger, consolidation or sale, and the Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the Common Stock for which this Warrant could have been exercised immediately prior to such merger, consolidation or sales would have been entitled, (B) in the case of a merger or consolidation, require the surviving entity to issue to the Holder a warrant entitling the Holder to acquire shares of such entity's common stock, which warrant shall have terms identical MUTATIS MUTANDIS (including with respect to exercise) to the terms of this Warrant and shall be entitled to all of the rights and privileges set forth herein and the agreements pursuant to which this Warrant was issued (including, without limitation, as such rights relate to the acquisition, transferability, registration and listing of such shares of stock or other securities issuable upon exercise thereof), or (C) in the event of an exchange or tender offer or other transaction contemplated by clause (3) of this Section 9(e), tender or exchange this Warrant for such securities, stock, cash and other property receivable upon or deemed to be held by holders of Common Stock that have tendered or exchanged their shares of Common Stock following such tender or exchange, and the Holder shall be entitled upon such exchange or tender to receive such amount of securities, cash and property as the shares of Common Stock for which this Warrant could have been exercised immediately prior to such tender or exchange would have been entitled as would have been issued (net of the applicable Exercise Price). In the case of clause (B), the exercise price applicable for the newly issued warrant shall be based upon the amount of securities, cash and property that each share of Common Stock would receive in such transaction and the Exercise Price immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger, sale, consolidation, tender or exchange shall include such terms so as continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or exercise following such event. This provision shall similarly apply to successive such events. (f) For the purposes of this Section 9, the following clauses shall also be applicable: (i) RECORD DATE. In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock or in securities convertible or exchangeable into shares of Common Stock, or (B) to subscribe for or purchase Common Stock or securities convertible or exchangeable into shares of Common Stock, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or 6 the date of the granting of such right of subscription or purchase, as the case may be. (ii) TREASURY SHARES. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock. (g) All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. (h) If (i) the Company shall declare a dividend (or any other distribution) on its Common Stock; or (ii) the Company shall declare a special nonrecurring cash dividend on or a redemption of its Common Stock; or (iii) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights; or (iv) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; or (v) the Company shall authorize the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall cause to be mailed to each Holder at their last addresses as they shall appear upon the Warrant Register, at least 30 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, grant of rights or warrants, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding up; provided, however, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. 10. PAYMENT OF EXERCISE PRICE. The Holder shall pay the Exercise Price in one of the following manners: (a) CASH EXERCISE. The Holder may deliver immediately available funds; or (b) CASHLESS EXERCISE. At any time after the earlier to occur of the SEC Effective Date (as defined in the Registration Rights Agreement) and the date the initial registration statement filed pursuant to the Registration Rights Agreement is declared effective by the Commission, when a registration statement covering the resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective, the Holder may surrender this Warrant to the Company together with a notice of cashless exercise, in which 7 event the Company shall issue to the Holder the number of Warrant Shares determined as follows: X = Y [(A-B)/A] where: X = the number of Warrant Shares to be issued to the Holder. Y = the number of Warrant Shares with respect to which this Warrant is being exercised. A = the average of the closing sale prices of the Common Stock for the five (5) trading days immediately prior to (but not including) the Date of Exercise. B = the Exercise Price. For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have been commenced, on the issue date of this Warrant. 11. CERTAIN EXERCISE RESTRICTIONS. (a) Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the Holder upon exercise pursuant to the terms hereof shall not exceed a number that, when added to the total number of shares of Common Stock deemed beneficially owned by such Holder (other than by virtue of the ownership of securities or rights to acquire securities that have limitations on the Holder's right to convert, exercise or purchase similar to the limitation set forth herein), together with all shares of Common Stock deemed beneficially owned (other than by virtue of the ownership of securities or rights to acquire securities that have limitation set forth herein) by the Holder's "affiliates" (as defined in Rule 144 of the Securities Act) ("Aggregation Parties"), that would be aggregated for purposes of determining whether a group under Section 13(d) of the Securities Exchange Act of 1934, as amended, exists would exceed 9.99% of the total issued and outstanding shares of the Common Stock (the "Restricted Ownership Percentage"). Each Holder shall have the right (w) at any time and from time to time to reduce its Restricted Ownership Percentage immediately upon notice to the Company and (x) (subject to waiver) at any time and from time to time, to increase its Restricted Ownership Percentage immediately in the event of the announcement as pending or planned, of a merger or consolidation of the Company, a sale of all or substantially all of the assets of the Company or the acquisition by any third party (and/or such party's Aggregation Parties) of at least 51% of the Company's outstanding Common Stock. (b) The Holder covenants at all times on each day (each such day being referred to as a "Covenant Day") as follows: during the balance of such Covenant Day and the succeeding sixty-one (61) days (the balance of such Covenant Day and the succeeding 61 8 days being referred to as the "Covenant Period") such Holder will not acquire shares of Common Stock pursuant to any right (including exercise of this Warrant) existing at the commencement of the Covenant Period to the extent the number of shares so acquired by such Holder and its Aggregation Parties (ignoring all dispositions) would exceed: (x) the Restricted Ownership Percentage of the total number of shares of Common Stock outstanding at the commencement of the Covenant Period; MINUS (y) the number of share of Common Stock owned by such Holder and its Aggregation Parties at the commencement of the Covenant Period. A new and independent covenant will be deemed to be given by the Holder as of each moment of each Covenant Day. No covenant will terminate, diminish or modify any other covenant. The Holder agrees to comply with each such covenant. The Company's obligation to issue shares of Common Stock which would exceed such limited shall be suspended to the extent necessary until such time, if any, as shares of Common Stock may be issued in compliance with such restrictions. 12. FRACTIONAL SHARES. The Company shall not be required to issue or cause to be issued fractional Warrant Shares on the exercise of this Warrant. The number of full Warrant Shares which shall be issuable upon the exercise of this Warrant shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of this Warrant so presented. If any fraction of a Warrant Share would, except for the provisions of this Section, be issuable on the exercise of this Warrant, the Company shall pay an amount in cash equal to the Exercise Price multiplied by such fraction. 13. NOTICES. Any and all notices or other communications or deliveries hereunder shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section prior to 6:30 p.m. (New York City time) on a business day, (ii) the business day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile telephone number specified in this Section later than 6:30 p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York City time) on such date, (iii) the business day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given.

WARRANT AGENT. The Company shall serve as warrant agent under this Warrant. Upon thirty (30) days' notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder's last address as shown on the Warrant Register. 15. MISCELLANEOUS. (a) This Warrant shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns.

(d) The headings herein are for convenience only, do not constitute a part of this Warrant and shall not be deemed to limit or affect any of the provisions hereof. (e) In case any one or more of the provisions of this Warrant shall be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt in good faith to agree upon a valid and enforceable provision which shall be 10 a commercially reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Warrant.
