The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of the date prior to the filing date of the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”).

The Company has not, in the 12 months preceding the Effective Date, received notice from any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market.

The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances, which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the date of the Commitment Closing. The SEC Reports set forth as of the dates thereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments.

5.11 Issuance of Additional Securities. The Company shall not issue additional Common Stock or securities convertible into Common Stock to any Person other than Investor, or an Investor Affiliate, if such issuance would reduce the number of remaining authorized shares of Common Stock that could be issued below the number of remaining authorized shares issuable upon exercise of the Warrants, without previously amending its Certificate of Incorporation to increase the number of duly authorized shares of Common Stock by at least the amount necessary to assume a sufficient number of shares to permit the exercise of all outstanding Warrants.

5.12 Prospectus Availability and Changes. The Company will make available to Investor upon request, and thereafter from time to time to furnish Investor, as many copies of any Prospectus (or of the Prospectus as amended or supplemented if the Company shall have made any amendments or supplements thereto after the effective date of the applicable Registration Statement) as Investor may request for the purposes contemplated by the Act; and in case Investor is required to deliver a prospectus after the nine-month period referred to in Section 10(a)(3) of the Act in connection with the sale of the Common Shares, or after the time a post-effective amendment to the applicable Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Act, the Company will prepare, at its expense, promptly upon request such amendment or amendments to the Registration Statement and the Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be.

MISCELLANEOUS

6.1 Fees and Expenses. Prior to the Effective Date, the Company shall have paid a $20,000.00 non-refundable document preparation fee to counsel for Investor.

No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

6.4 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.

6.5 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Investor, which consent will not be unreasonably withheld or delayed.

6.6 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 5.8.

6.7 Governing Law; Dispute Resolution. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

6.8 Survival. The representations and warranties contained herein shall survive the Closing and the delivery, exercise and/or conversion of the Securities, as applicable.

6.9 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or in a PDF file by e-mail transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

6.10 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.11 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution

therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.

6.12 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of Investor and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. Neither the Company nor Investor shall be liable for special, indirect, consequential or punitive damages suffered or alleged to be suffered by the other party or any third party, whether arising from or related to the Transaction Documents or otherwise.

6.13 Payment Set Aside. To the extent that the Company makes a payment or payments to Investor pursuant to any Transaction Document or Investor enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.14 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been canceled.

6.15 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments hereto.

6.16 Time of the Essence. Time is of the essence with respect to all provisions of this Agreement that specify a time for performance.

6.17 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties, and supersede all prior and contemporaneous agreements, term sheets, communications, discussions and understandings, oral or written, which the parties acknowledge have been merged into such documents, exhibits and schedules. Neither party has relied upon any agreement, promise or representation not expressly set forth in the Transaction Documents and each party agrees that it may only rely on the agreements, promises and representations set forth therein.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized signatories as of the date first indicated above.

Lock-Up Agreement

[Date]

Ladies and Gentlemen:

This Lock-Up Agreement is being delivered to you in connection with the Preferred Stock Purchase Agreement dated as of April [ ], 2010 (“Purchase Agreement”) and entered into by and among the undersigned and (“Investor”), with respect to the purchase pursuant to registration under the Securities Act of 1933, as amended (the “Act”) of shares of Series F Preferred Stock and related Securities of International Stem Cell Corporation, a Delaware corporation (“Company”). Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Purchase Agreement.

In order to induce Investor to enter into the Purchase Agreement, the undersigned agrees that, for a period of seven Trading Days beginning on the date the Company delivers a Preferred Stock Notice to Investor (the “Preferred Stock Notice Date”) and ending of after the Preferred Stock Closing Date pursuant to the terms of the Purchase Agreement (the “Lock-up Period”), the undersigned will not, without the prior written consent of Investor, (a) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Exchange Act”) with respect to, any Common Stock of the Company or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock or any such securities, or any securities substantially similar to the Common Stock, (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or any such securities, or warrants or other rights to purchase Common Stock, whether any such transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (c) publicly announce an intention to effect any transaction specified in clause (a) or (b).

The foregoing sentence shall not apply to (a) bona fide gifts, provided the recipient thereof agrees in writing to be bound by the terms of this Lock-Up Agreement, (b) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing to be bound by the terms of this Lock-Up Agreement, (c) sales made pursuant to any written sales plans established prior to the date of this Lock-Up Agreement in conformity with the requirements of Rule 10b5-1(c) promulgated under the Exchange Act or (d) exercise of options for Common Stock and the disposition

(whether by sale, gift or otherwise) of Common Stock underlying such options. Notwithstanding subsection (a) above, the undersigned may make a bona fide gift of up to 10,000 shares of Common Stock to a charity or other non-profit entity and such charity or entity shall not be required to be bound by the terms of this Lock-Up Agreement; provided, however, that in the event the undersigned exercises options during the Lock-Up Period, the undersigned may not, during the Lock-Up Period, dispose of the number of shares of Common Stock underlying such exercised options equal to the number of shares of Common Stock gifted by the undersigned pursuant to this sentence during the Lock-Up Period. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

The Company agrees to provide the undersigned with notice that the Company has delivered a Preferred Stock Notice to Investor prior to, or simultaneous with, its delivery of the Preferred Stock Notice to Investor. Such notice shall provide the undersigned with the Preferred Stock Notice Date and clearly indicate the beginning of the Lock-up Period.

Upon the termination of the Purchase Agreement, this Lock-Up Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.

Sincerely,

[Stockholder]
