Exhibit 10.4

ChromaDex, Inc.

Restricted Stock Purchase Agreement
under the 2007 Equity Incentive Plan

This Agreement is made by and between ChromaDex, Inc., a California corporation (the “Company”), and _____  (“Purchaser”).

R E C I T A L S

A Purchaser holds a notice of grant of right to purchase stock dated _____ (the “Notice of Grant”) to purchase shares of Common Stock (“Common Stock”) of the Company (the “Purchase Right”) pursuant to the Company’s 2007 Equity Incentive Plan (the “Plan”); and

B. The Purchase Right consists of the Notice and a Restricted Stock Purchase Agreement.

C. Purchaser desires to exercise the Purchase right on the terms and conditions contained herein.

A G R E E M E N T

In consideration of the foregoing recitals and the mutual covenants and conditions contained herein, the parties, intending to be legally bound, agree as follows:

1. Incorporation of Plan by Reference. This Agreement is subject to all of the terms and conditions as set forth in the Plan. If there is a conflict between the terms of this Agreement and the Plan, the terms of the Plan shall control. Defined terms not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan.

2. Purchase and Sale of Common Stock.

(a) Agreement to Purchase and Sell Common Stock. Purchaser hereby agrees to purchase from the Company, and the Company hereby agrees to sell to Purchaser, shares of the Common Stock of the Company in accordance with the Notice of Grant duly executed by Purchaser and attached hereto as Exhibit A. In accordance with the terms of the Option, the purchase price for the shares of Common Stock are payable by a Promissory Note substantially in the form set forth in Exhibit D, subject to a Pledge Agreement substantially in the form set forth in Exhibit E.

(b) Closing. The closing hereunder, including payment for and delivery of the Common Stock, shall occur at the offices of the Company immediately following the execution of this Agreement, or at such other time and place as the parties may mutually agree; provided, however, that if shareholder approval of the Plan is required before this Agreement may be executed, then the Notice of Grant may not be exercised, and the closing shall be delayed, until such shareholder approval is obtained. If such shareholder approval is not obtained within the time limit specified in the Plan, then this Agreement shall be null and void.

3. Repurchase Option. Upon the earlier of (i) the termination of Purchaser’s Continuous Service, or (ii) the occurrence of a Corporate Transaction and the Company opts to terminate the Plan pursuant to Section 10(c)(i) of the Plan, then the Company shall have an irrevocable option (the “Unvested Share Repurchase Option”) for a period of ninety (90) days after said termination or Corporate Transaction, or such longer period as may be agreed to by the Company and the Purchaser, to repurchase from Purchaser or Purchaser’s personal representative, as the case may be, those shares that Purchaser received pursuant to the exercise of the Notice of Grant. Pursuant to its repurchase option, the Company may repurchase all or any of the shares that Purchaser received pursuant to the exercise of the Notice of Grant that (a) have not as yet vested as of such termination or Corporate Transaction date in accordance with the Vesting Schedule indicated on Purchaser’s Notice of Grant (the “Unvested Shares”) at a price (“Option Price”) equal to the Purchaser’s Purchase Price for such shares as indicated on Purchaser’s Notice of Grant, and (b) have vested as of such termination or Corporate Transaction date in accordance with the Vesting Schedule indicated on Purchaser’s Notice of Grant (the “Vested Shares”) at a price equal to the Fair Market Value for such shares.

4. Exercise of Repurchase Option. The Repurchase Option shall be exercised by written notice signed by an Officer of the Company and delivered or mailed as provided herein. Such notice shall identify the number of shares of Common Stock to be purchased and shall notify Purchaser of the time, place and date for settlement of such purchase, which shall be scheduled by the Company within the term of the Repurchase Option set forth above. The Company shall be entitled to pay for any shares of Common Stock purchased pursuant to its Repurchase Option at the Company’s option in cash or by offset against any indebtedness owing to the Company by Purchaser (including without limitation any Note given in payment for the Common Stock), or by a combination of both. Upon delivery of such notice and payment of the purchase price in any of the ways described above, the Company shall become the legal and beneficial owner of the Common Stock being repurchased and all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the Common Stock being repurchased by the Company, without further action by Purchaser.

5. Capitalization Adjustments to Common Stock. In the event of a “Capitalization Adjustment” affecting the Company’s outstanding Common Stock as a class as designated in the Plan, then any and all new, substituted or additional securities or other property to which Purchaser is entitled by reason of Purchaser’s ownership of Common Stock shall be immediately subject to the Repurchase Option and be included in the word “Common Stock” for all purposes of the Repurchase Option with the same force and effect as the shares of the Common Stock presently subject to the Repurchase Option, but only to the extent the Common Stock is, at the time, covered by such Repurchase Option. While the total Option Price shall remain the same after each such event, the Option Price per share of Common Stock upon exercise of the Repurchase Option shall be appropriately adjusted.

6. Corporate Transactions. In the event of a Corporate Transaction described in the Plan, then the Repurchase Option may be assigned by the Company to the successor of the Company (or such successor’s parent company), if any, in connection with such Corporate Transaction. To the extent the Repurchase Option remains in effect following such Corporate Transaction, it shall apply to the new capital stock or other property received in exchange for the Common Stock in consummation of the Corporate Transaction, but only to the extent the Common Stock was at the time covered by such right. Appropriate adjustments shall be made to the price per share payable upon exercise of the Repurchase Option to reflect the Corporate Transaction upon the Company’s capital structure; provided, however, that the aggregate Option Price shall remain the same.

7. Escrow of Unvested Common Stock. As security for Purchaser’s faithful performance of the terms of this Agreement and to insure the availability for delivery of Purchaser’s Common Stock upon exercise of the Repurchase Option herein provided for, Purchaser agrees, at the closing hereunder, to deliver to and deposit with the Secretary of the Company or the Secretary’s designee (“Escrow Agent”), as Escrow Agent in this transaction, three (3) stock assignments duly endorsed (with date and number of shares blank) in the form attached hereto as Exhibit B, together with a certificate or certificates evidencing all of the Common Stock subject to the Repurchase Option; said documents are to be held by the Escrow Agent and delivered by said Escrow Agent pursuant to the Joint Escrow Instructions of the Company and Purchaser set forth in Exhibit C, attached hereto and incorporated by this reference, which instructions shall also be delivered to the Escrow Agent at the closing hereunder.

8. Rights of Purchaser. Subject to the provisions of this Agreement, Purchaser shall exercise all rights and privileges of a shareholder of the Company with respect to the shares deposited in escrow. Purchaser shall be deemed to be the holder of the shares for purposes of receiving any dividends that may be paid with respect to such shares and for purposes of exercising any voting rights relating to such shares, even if some or all of such shares have not yet vested and been released from the Company’s Repurchase Option.

9. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not sell, assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Common Stock while the Common Stock is subject to the Repurchase Option. After any Common Stock has been released from the Repurchase Option, Purchaser shall not sell, assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Common Stock except in compliance with the provisions herein and applicable securities laws. Furthermore, the Common Stock shall be subject to any right of first refusal in favor of the Company or its assignees that may be contained in the Company’s Bylaws.

10. Restrictive Legends. All certificates representing the Common Stock shall have endorsed thereon legends in substantially the following forms (in addition to any other legend which may be required by other agreements between the parties hereto):

(a) “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN OPTION SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS COMPANY. ANY TRANSFER OR ATTEMPTED TRANSFER OF ANY SHARES SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN CONSENT OF THE COMPANY.”

(b) “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.”

(c) Any legend required by appropriate blue sky officials.

11. Investment Representations. In connection with the purchase of the Common Stock, Purchaser represents to the Company the following:

(a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Common Stock. Purchaser is acquiring the Common Stock for investment for Purchaser’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act.

(b) Purchaser understands that the Common Stock has not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein.

(c) Purchaser further acknowledges and understands that the Common Stock must be held indefinitely unless the Common Stock is subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the Common Stock. Purchaser understands that the certificate evidencing the Common Stock will be imprinted with a legend that prohibits the transfer of the Common Stock unless the Common Stock is registered or such registration is not required in the opinion of counsel for the Company.

(d) Purchaser is familiar with the provisions of Rules 144 and 701, under the Securities Act, as in effect from time to time, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of issuance of the securities, such issuance will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the securities exempt under Rule 701 may be sold by Purchaser ninety (90) days thereafter, subject to the satisfaction of certain of the conditions specified by Rule 144.

(e) In the event that the sale of the Common Stock does not qualify under Rule 701 at the time of purchase, then the Common Stock may be resold by Purchaser in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things: (i) the availability of certain public information about the Company and (ii) the resale occurring following the required holding period under Rule 144 after the Purchaser has purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold.

(f) Purchaser further understands that at the time Purchaser wishes to sell the Common Stock there may be no public market upon which to make such a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public current information requirements of Rule 144 or 701, and that, in such event, Purchaser would be precluded from selling the Common Stock under Rule 144 or 701 even if the minimum holding period requirement had been satisfied.

12. Section 83(b) Election. Purchaser understands that Section 83(a) of the Code, taxes as ordinary income the difference between the amount paid for the Common Stock and the fair market value of the Common Stock as of the date any restrictions on the Common Stock lapse. In this context, “restriction” includes the right of the Company to buy back the Unvested Shares pursuant to the Repurchase Option set forth above. Purchaser understands that Purchaser may elect to be taxed at the time the Common Stock is purchased, rather than when and as the Repurchase Option expires, by filing an election under Section 83(b) (an “83(b) Election”) of the Code with the Internal Revenue Service within thirty (30) days from the date of purchase. Even if the fair market value of the Common Stock at the time of the execution of this Agreement equals the amount paid for the Common Stock, the 83(b) Election must be made to avoid income under Section 83(a) in the future. Purchaser understands that failure to file such an 83(b) Election in a timely manner may result in adverse tax consequences for Purchaser. Purchaser further understands that Purchaser must file an additional copy of such 83(b) Election with his or her federal income tax return for the calendar year in which the date of this Agreement falls. Purchaser acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to purchase of the Common Stock hereunder, and does not purport to be complete. Purchaser further acknowledges that the Company has directed Purchaser to seek independent advice regarding the applicable provisions of the Code, the income tax laws of any municipality, state or foreign country in which Purchaser may reside, and the tax consequences of Purchaser’s death. Purchaser assumes all responsibility for filing an 83(b) Election and paying all taxes resulting from such election or the lapse of the restrictions on the Common Stock.

13. Refusal to Transfer. The Company shall not be required (a) to transfer on its books any shares of Common Stock of the Company which shall have been transferred in violation of any of the provisions set forth in this Agreement or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares shall have been so transferred.

14. No Employment Rights. This Agreement is not an employment contract and nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company (or a parent or subsidiary of the Company) to terminate Purchaser’s employment for any reason at any time, with or without cause and with or without notice.

15. Miscellaneous.

(a) Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or sent by telegram or fax or upon deposit in the United States Post Office, by registered or certified mail with postage and fees prepaid, addressed to the other party hereto at such party’s address hereinafter shown below its signature or at such other address as such party may designate by ten (10) days’ advance written notice to the other party hereto.

(b) Successors and Assigns. This Agreement shall inure to the benefit of the successors and assigns of the Company and, subject to the restrictions on transfer herein set forth, be binding upon Purchaser, Purchaser’s successors, and assigns. The Company may assign the Repurchase Option hereunder at any time or from time to time, in whole or in part.

(c) Attorneys’ Fees; Specific Performance. Purchaser shall reimburse the Company for all costs incurred by the Company in enforcing the performance of, or protecting its rights under, any part of this Agreement, including reasonable costs of investigation and attorneys’ fees. It is the intention of the parties that the Company, upon exercise of the Repurchase Option and payment of the Option Price, pursuant to the terms of this Agreement, shall be entitled to receive the Common Stock, in specie, in order to have such Common Stock available for future issuance without dilution of the holdings of other shareholders. Furthermore, it is expressly agreed between the parties that money damages are inadequate to compensate the Company for the Common Stock and that the Company shall, upon proper exercise of the Repurchase Option, be entitled to specific enforcement of its rights to purchase and receive said Common Stock.

(d) Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of California. The parties agree that any action brought by either party to interpret or enforce any provision of this Agreement shall be brought in, and each party agrees to, and does hereby, submit to the jurisdiction and venue of, the appropriate state or federal court for the district encompassing the Company’s principal place of business.

(e) Further Execution. The parties agree to take all such further action(s) as may reasonably be necessary to carry out and consummate this Agreement as soon as practicable, and to take whatever steps may be necessary to obtain any governmental approval in connection with or otherwise qualify the issuance of the securities that are the subject of this Agreement.

(f) Independent Counsel. Purchaser acknowledges that this Agreement has been prepared on behalf of the Company by Manatt, Phelps & Phillips, LLP, counsel to the Company and that Manatt, Phelps & Phillips, LLP does not represent, and is not acting on behalf of, Purchaser. Purchaser has been provided with an opportunity to consult with Purchaser’s own counsel with respect to this Agreement.

(g) Entire Agreement; Amendment. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes and merges all prior agreements or understandings, whether written or oral. This Agreement may not be amended, modified or revoked, in whole or in part, except by an agreement in writing signed by each of the parties hereto.

(h) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

(i) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

In witness whereof, the parties hereto have executed this Agreement as of this _____ day of _____ 200 _____ .

STOCK PLEDGE AGREEMENT

This Stock Pledge Agreement (“Pledge Agreement”) is made by _____ (“Pledgor”), in favor of ChromaDex, Inc.., a California corporation with its principal place of business at ChromaDex, Inc., 10005 Muirlands Boulevard, Suite G, 1st Floor, Irvine, CA 92618 (“Pledgee”).

Whereas, Pledgor has concurrently herewith executed that certain Promissory Note (the “Note”) in favor of Pledgee in the amount of _____ Dollars ($ _____ ) in payment of the purchase price of _____ ( _____ ) shares of the Common Stock of Pledgee; and

Whereas, Pledgee is willing to accept the Note from Pledgor, but only upon the condition, among others, that Pledgor shall have executed and delivered to Pledgee this Pledge Agreement and the Collateral (as defined below):

Now, Therefore, in consideration of the foregoing recitals and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and intending to be legally bound, Pledgor hereby agrees as follows:

1. As security for the full, prompt and complete payment and performance when due (whether by stated maturity, by acceleration or otherwise) of all indebtedness of Pledgor to Pledgee created under the Note (all such indebtedness being the “Liabilities”), together with, without limitation, the prompt payment of all expenses, including, without limitation, reasonable attorneys’ fees and legal expenses, incidental to the collection of the Liabilities and the enforcement or protection of Pledgee’s lien in and to the collateral pledged hereunder, Pledgor hereby pledges to Pledgee, and grants to Pledgee, a first priority security interest in all of the following (collectively, the “Pledged Collateral”):

The term “indebtedness” is used herein in its most comprehensive sense and includes any and all advances, debts, obligations and Liabilities heretofore, now or hereafter made, incurred or created, whether voluntary or involuntary and whether due or not due, absolute or contingent, liquidated or unliquidated, determined or undetermined, and whether recovery upon such indebtedness may be or hereafter becomes unenforceable.

2. At any time, without notice, and at the expense of Pledgor, Pledgee in its name or in the name of its nominee or of Pledgor may, but shall not be obligated to: (1) collect by legal proceedings or otherwise all dividends (except cash dividends other than liquidating dividends), interest, principal payments and other sums now or hereafter payable upon or on account of said Pledged Collateral; (2) enter into any extension, reorganization, deposit, merger or consolidation agreement, or any agreement in any way relating to or affecting the Pledged Collateral, and in connection therewith may deposit or surrender control of such Pledged Collateral thereunder, accept other property in exchange for such Pledged Collateral and do and perform such acts and things as it may deem proper, and any money or property received in exchange for such Pledged Collateral shall be applied to the indebtedness or thereafter held by it pursuant to the provisions hereof; (3) insure, process and preserve the Pledged Collateral; (4) cause the Pledged Collateral to be transferred to its name or to the name of its nominee; (5) exercise as to such Pledged Collateral all the rights, powers and remedies of an owner, except that so long as no default exists under the Note or hereunder Pledgor shall retain all voting rights as to the Pledged Shares.

3. Pledgor agrees to pay prior to delinquency all taxes, charges, liens and assessments against the Pledged Collateral, and upon the failure of Pledgor to do so, Pledgee at its option may pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same.

4. At the option of Pledgee and without necessity of demand or notice, all or any part of the indebtedness of Pledgor shall immediately become due and payable irrespective of any agreed maturity, upon the happening of any of the following events: (1) failure to keep or perform any of the terms or provisions of this Pledge Agreement; (2) failure to pay any installment of principal or interest on the Note when due; (3) the levy of any attachment, execution or other process against the Pledged Collateral; or (4) the insolvency, commission of an act of bankruptcy, general assignment for the benefit of creditors, filing of any petition in bankruptcy or for relief under the provisions of Title 11 of the United States Code of, by, or against Pledgor.

5. In the event of the nonpayment of any indebtedness when due, whether by acceleration or otherwise, or upon the happening of any of the events specified in the last preceding section, Pledgee may then, or at any time thereafter, at its election, apply, set off, collect or sell in one or more sales, or take such steps as may be necessary to liquidate and reduce to cash in the hands of Pledgee in whole or in part, with or without any previous demands or demand of performance or notice or advertisement, the whole or any part of the Pledged Collateral in such order as Pledgee may elect, and any such sale may be made either at public or private sale at its place of business or elsewhere, or at any broker’s board or securities exchange, either for cash or upon credit or for future delivery; provided, however, that if such disposition is at private sale,

then the purchase price of the Pledged Collateral shall be equal to the public market price then in effect, or, if at the time of sale no public market for the Pledged Collateral exists, then, in recognition of the fact that the sale of the Pledged Collateral would have to be registered under the Securities Act of 1933 and that the expenses of such registration are commercially unreasonable for the type and amount of collateral pledged hereunder, Pledgee and Pledgor hereby agree that such private sale shall be at a purchase price mutually agreed to by Pledgee and Pledgor or, if the parties cannot agree upon a purchase price, then at a purchase price established by a majority of three independent appraisers knowledgeable of the value of such collateral, one named by Pledgor within ten (10) days after written request by the Pledgee to do so, one named by Pledgee within such 10-day period, and the third named by the two appraisers so selected, with the appraisal to be rendered by such body within thirty (30) days of the appointment of the third appraiser. The cost of such appraisal, including all appraiser’s fees, shall be charged against the proceeds of sale as an expense of such sale. Pledgee may be the purchaser of any or all Pledged Collateral so sold and hold the same thereafter in its own right free from any claim of Pledgor or right of redemption. Demands of performance, notices of sale, advertisements and presence of property at sale are hereby waived, and Pledgee is hereby authorized to sell hereunder any evidence of debt pledged to it. Any officer or agent of Pledgee may conduct any sale hereunder.

6. The proceeds of the sale of any of the Pledged Collateral and all sums received or collected by Pledgee from or on account of such Pledged Collateral shall be applied by Pledgee to the payment of expenses incurred or paid by Pledgee in connection with any sale, transfer or delivery of the Pledged Collateral, to the payment of any other costs, charges, attorneys’ fees or expenses mentioned herein, and to the payment of the indebtedness or any part hereof, all in such order and manner as Pledgee in its discretion may determine. Pledgee shall then pay any balance to Pledgor.

7. Upon the transfer of all or any part of the indebtedness Pledgee may transfer all or any part of the Pledged Collateral and shall be fully discharged thereafter from all liability and responsibility with respect to such Pledged Collateral so transferred, and the transferee shall be vested with all the rights and powers of Pledgee hereunder with respect to such Pledged Collateral so transferred; but with respect to any Pledged Collateral not so transferred Pledgee shall retain all rights and powers hereby given.

8. Until all indebtedness shall have been paid in full the power of sale and all other rights, powers and remedies granted to Pledgee hereunder shall continue to exist and may be exercised by Pledgee at any time and from time to time irrespective of the fact that the indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Pledgor may have ceased.

9. Pledgee agrees that so long as no default exists under the Note or hereunder, the Pledged Shares shall, upon the request of Pledgor, be released from pledge as the indebtedness is paid. Such releases shall be at the rate of one share for each _____ ($ _____ ) of principal amount of indebtedness paid. Release from pledge, however, shall not result in release from the provisions of those certain Joint Escrow Instructions, if any, of even date herewith among the parties to this Pledge Agreement and the Escrow Agent named therein.

10. Pledgee may at any time deliver the Pledged Collateral or any part thereof to Pledgor and the receipt of Pledgor shall be a complete and full acquittance for the Pledged Collateral so delivered, and Pledgee shall thereafter be discharged from any liability or responsibility therefor.

11. The rights, powers and remedies given to Pledgee by this Pledge Agreement shall be in addition to all rights, powers and remedies given to Pledgee by virtue of any statute or rule of law. Any forbearance or failure or delay by Pledgee in exercising any right, power or remedy hereunder shall not be deemed to be a waiver of such right, power or remedy, and any single or partial exercise of any right, power or remedy hereunder shall not preclude the further exercise thereof; and every right, power and remedy of Pledgee shall continue in full force and effect until such right, power or remedy is specifically waived by an instrument in writing executed by Pledgee.

12. If any provision of this Pledge Agreement is held to be unenforceable for any reason, it shall be adjusted, if possible, rather than voided in order to achieve the intent of the parties to the extent possible. In any event, all other provisions of this Pledge Agreement shall be deemed valid and enforceable to the full extent possible.

13. This Pledge Agreement shall be governed by, and construed in accordance with, the laws of the State of California as applied to contracts made and performed entirely within the State of California by residents of such State.
