SYNERGY PHARMACEUTICALS INC. RESTRICTED STOCK PURCHASE AGREEMENT

Exhibit 10.3

SYNERGY PHARMACEUTICALS INC.

RESTRICTED STOCK PURCHASE AGREEMENT

THIS AGREEMENT is made as of July       2008 at New York, New York, between Synergy Pharmaceuticals Inc. a Delaware corporation (the “Company”), and                                                                             (the “Purchaser”).

WHEREAS the Purchaser is a service provider of the Company, and the Purchaser’s continued participation is considered by the Company to be important for the Company’s continued growth; and

WHEREAS in order to give the Purchaser an opportunity to acquire an equity interest in the Company as an incentive for the Purchaser to participate in the affairs of the Company, the Company has agreed to sell the Purchaser shares of its Common Stock as set forth in this Restricted Stock Purchase Agreement (the “Agreement”).

THEREFORE, the parties agree as follows:

1.                                       Sale of Stock. The Company hereby agrees to sell to the Purchaser and the Purchaser hereby agrees to purchase                  shares of the Company’s Common Stock (the “Shares”), at a price of $0.001 per share.

2.                                       Payment of Purchase Price. The purchase price for the Shares is payable on or before 5:30PM New York Time on the third business days following the date of this Agreement by delivery of a check to the Company.  The failure to make payment by that date and time will void the sale of the Shares and relieve the Company of any obligations under this Agreement.

3.                                       Repurchase Option.

(a)                                  In the event the Purchaser ceases to be an employee, officer, director or consultant of or to the Company (any such position constituting a “Service Provider”) for any reason, except the termination of Purchaser’s position by the Company, or no reason (including death or disability) before all of the Shares are released from the Company’s repurchase option (see Section 4), the Company shall, upon the date of such termination (as reasonably fixed and determined by the Company) have an irrevocable, exclusive option for a period of sixty (60) days from such date to repurchase up to that number of shares which constitute the Unreleased Shares (as defined in Section 4) at the original purchase price per share (the “Repurchase Price”). Said option shall be exercised by the Company by delivering written notice to the Purchaser or the Purchaser’s executor (with a copy to the Escrow Holder (as defined in Section 6)) AND, at the Company’s option, by delivering to the Purchaser or the Purchaser’s executor a check in the amount of the aggregate Repurchase Price. Upon delivery of such notice and the payment of the aggregate Repurchase Price in any of the ways described above, the Company shall become the legal and beneficial owner of the Shares being repurchased and all rights and interests therein or relating thereto, and the Company shall have the right to retain and transfer to its own name the number of Shares being repurchased by the Company.

(b)                                   Whenever the Company shall have the right to repurchase Shares hereunder, the Company may designate and assign one or more employees, officers, directors of the Company or other persons or organizations to exercise all or a part of the Company’s purchase rights under this Agreement and purchase all or a part of such Shares.

4.                                       Release of Shares From Repurchase Option.

(a)                                    50% of the Shares shall be released from the Company’s repurchase option one year after the date of this Agreement; and the remaining 50% of the Shares shall be released from the repurchase option two years after such date, subject to Purchaser continuing to be a Service Provider on such dates.

(b)                                   In the event of a “Change of Control” of the Company, all of the Shares shall be released from the Company’s repurchase option, unless the transaction constituting a Change in Control includes an exchange of Shares for Shares of another company and the Company assigns and such other Company assumes this Agreement.  For this purpose, a “Change of Control” is defined as:

(i)                                       Any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (other than a group consisting of the Company’s shareholders as of the date of the Closing and their Parents and Subsidiaries) becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then outstanding voting securities; or

(ii)                                    The consummation of a merger, consolidation, reorganization, sale of stock or similar transaction in which the shareholders of the Company before such transaction (and their Parents and Subsidiaries) own less than 50% of the voting stock or voting power of the surviving entity immediately after such transaction; or

(iii)                                 The consummation of the sale or disposition of all or substantially all of the Company’s assets.

(c)                                    Any of the Shares which have not yet been released from the Company’s repurchase option are referred to herein as “Unreleased Shares.”

(d)                                   The Shares which have been released from the Company’s repurchase option shall be delivered to the Purchaser at the Purchaser’s request (see Section 6).

5.                                     Restriction on Transfer. Except for the escrow described in Section 6 or transfer of the Shares to the Company or its assignees contemplated by this Agreement, none of the Shares or any beneficial interest therein shall be transferred, encumbered or otherwise disposed of in any way until the release of such Shares from the Company’s repurchase option in

accordance with the provisions of this Agreement, other than by will or the laws of descent and distribution.

6.                                     Escrow of Shares.

(a)                                    To ensure the availability for delivery of the Purchaser’s Unreleased Shares upon repurchase by the Company pursuant to the Company’s repurchase option under Section 3 above, the Purchaser shall, upon execution of this Agreement, deliver and deposit with the Secretary of the Company (the “Escrow Holder”) the share certificates representing the Unreleased Shares, together with the stock assignment duly endorsed in blank, attached hereto as Exhibit A-1. The Unreleased Shares and stock assignment shall be held by the Escrow Holder, pursuant to the Joint Escrow Instructions of the Company and Purchaser attached as Exhibit A-2 hereto, until such time as the Company’s repurchase option expires. As a further condition to the Company’s obligations under this Agreement, the spouse of Purchaser, if any, shall execute and deliver to the Company the Consent of Spouse attached hereto as Exhibit A-3.

(b)                                   The Escrow Holder shall not be liable for any act it may do or omit to do with respect to holding the Unreleased Shares in escrow and while acting in good faith and in the exercise of its judgment.

(c)                                    If the Company or any assignee exercises its repurchase option hereunder, the Escrow Holder, upon receipt of written notice of such option exercise from the proposed transferee, shall take all steps necessary to accomplish such transfer.

(d)                                   When the repurchase option has been exercised or expires unexercised or a portion of the Shares has been released from such repurchase option, upon Purchaser’s request the Escrow Holder shall promptly cause a new certificate to be issued for such released Shares and shall deliver such certificate to the Company or the Purchaser, as the case may be.

(e)                                    Subject to the terms hereof, the Purchaser shall have all the rights of a shareholder with respect to such Shares while they are held in escrow, including without limitation, the right to vote the Shares and receive any cash dividends declared thereon. If, from time to time during the term of the Company’s repurchase option, there is (i) any stock dividend, stock split or other change in the Shares, or (ii) any merger or sale of all or substantially all of the assets or other acquisition of the Company, any and all new, substituted or additional securities to which the Purchaser is entitled by reason of the Purchaser’s ownership of the Shares shall be immediately subject to this escrow, deposited with the Escrow Holder and included thereafter as “Shares” for purposes of this Agreement and the Company’s repurchase option.

7.                                     Legends.

(a)                                    The Shares are being issued to the Purchaser in reliance on certain exemptions from the registration requirements of state and federal securities laws, and as a condition of the Company selling the Shares to the Purchaser the Purchaser will execute and deliver to the Company the Investor Representation Statement in the form annexed hereto as Exhibit B.

(b)                                   Purchaser understands and agrees that the Company shall cause the legends set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by applicable state or federal securities laws:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH, THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, INCLUDING A REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND REPURCHASE OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

(c)                                    Stop-Transfer Notices. Purchaser agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

(d)                                   Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

8.                                     Adjustment for Stock Split. All references to the number of Shares and the purchase price of the Shares in this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend or other change in the Shares which may be made by the Company after the date of this Agreement or the proportionate amount of another issuer’s shares that have been exchanged in a transaction constituting a Change in Control.

9.                                     Tax Consequences. The Purchaser has reviewed with the Purchaser’s own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement. The Purchaser is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Purchaser understands that the Purchaser (and not the Company) shall be responsible for the Purchaser’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. The Purchaser understands that Section 83 of the Internal Revenue Code of 1986, as amended (the “Code”), taxes as ordinary income the difference between the purchase price for the Shares and the Fair Market Value of the Shares as of the date any restrictions on the

Shares lapse. In this context, “restriction” includes the right of the Company to buy back the Shares pursuant to its repurchase option. The Purchaser understands that the Purchaser may elect to be taxed at the time the Shares are purchased rather than when and as the Company’s repurchase option expires by filing an election under Section 83(b) of the Code with the I.R.S. within thirty (30) days from the date of purchase. The form for making this election is attached as Exhibit A-5 hereto.  In connection with such decisions, the Company will make available to the Purchaser and the Purchaser’s tax advisor, in each case on a confidential basis, the most recent final report of experts determining the fair market value of the Company nearest the date of this Agreement.

THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER’S SOLE RESPONSIBILITY AND NOT THE COMPANY’S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON THE PURCHASER’S BEHALF.

10.                               General Provisions.

(a)                                  This Agreement shall be governed by the laws of the State of Deleware. This Agreement represents the entire agreement between the parties with respect to the purchase of Common Stock by the Purchaser.

(b)                                 Any notice, demand or request required or permitted to be given by either the Company or the Purchaser pursuant to the terms of this Agreement shall be in writing and shall be deemed given when delivered personally or deposited in the U.S. mail, First Class with postage prepaid, and addressed to the parties at the addresses of the parties set forth at the end of this Agreement or such other address as a party may request by notifying the other in writing.

(c)                                  The rights and benefits of the Company under this Agreement shall be transferable to any one or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of the Purchaser under this Agreement may only be assigned with the prior written consent of the Company.

(d)                                 Either party’s failure to enforce any provision or provisions of this Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Agreement. The rights granted both parties herein are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances.

(e)                                  The Purchaser agrees upon request to execute any further documents or instruments necessary or desirable to carry out the purposes or intent of this Agreement.

(f)                                    PURCHASER ACKNOWLEDGES AND AGREES THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY PURSUANT TO SECTION 4 HEREOF IS EARNED ONLY BY CONTINUING AS A

SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES HEREUNDER). PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH PURCHASER’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE PURCHASER’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

By Purchaser’s signature below, Purchaser represents that he is familiar with the terms and provisions of this Agreement and hereby accepts this Agreement subject to all of the terms and provisions thereof Purchaser has reviewed this Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully understands all provisions of this Agreement.

EXHIBIT B

INVESTMENT REPRESENTATION STATEMENT

In connection with the purchase of the above Securities (exercising a “Stock Purchase Right”), the undersigned 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 Securities. Purchaser is acquiring these Securities 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 of 1933, as amended (the “Securities Act”).

(b)                               Purchaser acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. In this connection, Purchaser understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Purchaser’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the future. Purchaser further understands that the Securities must be held indefinitely unless they are 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 Securities. Purchaser understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company, and any other legend required under applicable state securities laws.

(c)                                Purchaser is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, 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 the grant of the Stock Purchase Right to the Purchaser, the exercise 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, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt under Rule 701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule 144, including: (1)(A) the Securities being held and the full purchase price paid not less that six months before such resale but only if certain public information about the Company is available or (B) the Securities being held and the full purchase price paid not less that one year before such resale; and, in the case of an affiliate, (A) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934), (B) certain public information about the Company is available, (3) the amount of Securities being sold during any three (C) month period not exceeding the limitations specified in Rule 144, and (D) the timely filing of a Form 144, if applicable.

In the event that the Company does not qualify under Rule 701 at the time of grant of the Stock Purchase Right, then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires the resale to occur not less than one (1) year after the later of the date the Securities were sold by the Company or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; and, in the case of acquisition of the Securities by an affiliate, or by a non-affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3) and (4) of the paragraph immediately above.

(d)                               Purchaser hereby agrees that if so requested by the Company or any representative of the underwriters in connection with any registration of the offering of any securities of the Company under the Securities Act, Purchaser shall not sell or otherwise transfer any Shares or other securities of the Company during the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act; provided, however, that such restriction shall only apply to the first registration statement of the Company to become effective under the Securities Act which include securities to be sold on behalf of the Company to the public in an underwritten public offering under the Securities Act. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period.

(e)                                Purchaser further understands that in the event all of the applicable requirements of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for

such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Purchaser understands that no assurances can be given that any such other registration exemption will be available in such event.
