GT SOLAR INTERNATIONAL, INC.

RESTRICTED STOCK AGREEMENT

        THIS AGREEMENT (the "Agreement") is made as of March 17, 2008, by and between GT Solar International, Inc., a Delaware corporation (the "Company"), and Robert W. Woodbury ("Executive").

        The Company and Executive desire to enter into an agreement pursuant to which the Company shall grant to Executive five thousand (5,000) shares of the Company's common stock, par value $.01 per share (the "Common Stock"). All of such shares of Common Stock and all shares of Common Stock hereafter acquired by Executive pursuant to this Agreement are referred to herein as "Executive Stock." The issuance of shares of Executive Stock to Executive hereunder is intended to be exempt from registration under the Securities Act of 1933 pursuant to Rule 701 thereunder. Certain definitions are set forth in Section 6 of this Agreement.

        The parties hereto agree as follows:

        1.    Grant of Executive Stock.

        (a)   The Company hereby grants to Executive, as of the date hereof, 5,000 shares of Common Stock, subject to the terms and conditions hereunder. Executive agrees and understands that nothing contained in this Agreement provides, or is intended to provide, Executive with any protection against potential future dilution of Executive's stockholder interest in the Company for any reason.

        (b)   The grant of the Executive Stock by the Company is subject to Executive's execution and delivery of the Employment Agreement between Executive and the Company.

        (c)   In connection with the receipt of the Executive Stock hereunder, Executive represents and warrants to, and agrees with, the Company that:

          (i)  The Executive Stock to be acquired by Executive pursuant to this Agreement shall be acquired for Executive's own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, or any applicable state securities laws, and the Executive Stock shall not be disposed of in contravention of the Securities Act or any applicable state securities laws.

         (ii)  Executive acknowledges that the Executive Stock has not been registered under the Securities Act and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.

        (iii)  Executive is the chief financial officer of the Company, is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Executive Stock.

        (iv)  Executive is able to bear the economic risk of holding the Executive Stock for an indefinite period of time because the Executive Stock has not been registered under the Securities Act and, therefore, cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available.

         (v)  Executive is an "accredited investor" as such term is defined in Rule 501 under the Securities Act.

        (vi)  Executive has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of Executive Stock and has had full access to such other information concerning the Company as he has requested. Executive has reviewed, or has had an opportunity to review, the following documents: (A) the Company's Certificate of Incorporation and Bylaws, and (B) the Stockholders' Agreement.

       (vii)  This Agreement constitutes the legal, valid and binding obligation of Executive, enforceable in accordance with its terms, and the execution, delivery and performance of this

Agreement by Executive do not and shall not conflict with, violate or cause a breach of any agreement, contract or instrument to which Executive is a party or any judgment, order or decree to which Executive is subject.

      (viii)  Executive has not taken any action that constitutes a conflict with, violation or breach of, and the execution and delivery of this Agreement and the other agreements contemplated hereby will not conflict with, violate or cause a breach of, any noncompete, nonsolicitation or confidentiality agreement to which Executive is a party or by which Executive is bound. Executive agrees to notify the Board of any matter (including, but not limited to, any potential acquisition by the Company) which, to Executive's knowledge, might reasonably be expected to violate or cause a breach of any such agreement.

        (ix)  Executive is a resident of the Commonwealth of Massachusetts.

         (x)  Executive has been advised and encouraged in writing (via this Agreement) to consult with an attorney and a tax advisor prior to signing this Agreement.

        (d)   As an inducement to the Company to issue the Executive Stock to Executive, and as a condition thereto, Executive acknowledges and agrees that neither the issuance of the Executive Stock to Executive nor any provision contained herein shall entitle Executive to remain in the employment of the Company and its Subsidiaries or affect the right of the Company to terminate Executive's employment at any time, with or without cause.

        (e)   The Company and Executive acknowledge and agree that this Agreement has been executed and delivered, and the Executive Stock has been issued hereunder, in connection with and as a part of the compensation and incentive arrangements between the Company and Executive.

        (f)    In connection with the grant of the Executive Stock hereunder, Executive hereby agrees and acknowledges that all of the shares of Executive Stock are subject in all respects to the terms of this Agreement, the Stockholders' Agreement (as if the shares of Executive Stock were "Covered Shares," as defined in such agreement), and the Registration Rights Agreement, each as may be amended from time to time. In addition, Executive hereby accepts all the terms and conditions of (i) the Stockholders' Agreement, which terms and conditions include restrictions on transfer and rights of repurchase in favor of the Company, and agrees to be bound in all respects as an "Executive Stockholder" thereunder, and (ii) the Registration Rights Agreement. Notwithstanding the foregoing, Executive agrees and acknowledges that under no circumstances may any unvested shares of Executive Stock be transferred to any Person except in connection with a Drag Along Transaction (as defined in the Stockholders' Agreement) pursuant to the Stockholders' Agreement.

        2.    Vesting of Executive Stock.

        (a)   Except as otherwise provided in this Section 2, the Executive Stock shall become vested in accordance with the following schedule, if as of each such date Executive is employed by the Company or any of its Subsidiaries, such that, subject to the other terms and conditions of this Agreement, all of the Executive Stock shall be vested on the fourth anniversary of the Employment Agreement:

The Board, or a duly designated committee thereof, in its sole discretion, may determine, prior to or within 90 days after the date of any such termination, that all or a portion of any of Executive's unvested shares of Executive Stock shall not be so cancelled and forfeited.

        (c)   In the event that Executive's employment with the Company or one of its Subsidiaries is terminated for "Cause" (as defined in the Employment Agreement) or if Executive fails to comply with any of the covenants binding Executive in the Stockholders' Agreement, the Company may cancel any outstanding Executive Stock, whether vested or unvested.

        (d)   In addition to Sections 2(a)-(b) above, upon a termination without Cause (as defined in the Employment Agreement) of Executive's employment with the Company within twelve months following a "Change in Control" of the Company (the "Termination"), the Executive Stock shall vest as follows: (A) if the Termination occurs on or before January 2, 2009, 1/4th of the Executive Stock shall vest on the date of the Termination and (B) if the Termination occurs after January 2, 2009, on the date of the Termination a number of shares of Executive Stock (not to exceed the number of unvested shares of Executive Stock as of immediately prior to Termination) shall vest that is equal to the product of (x) 1/48th of the Executive Stock and (y) the number of full months passed between January 2, 2008and the date of the Termination (for the avoidance of doubt, the vesting described in this Section 2(d) is in addition to, and not in lieu of, any vesting described in Sections 2(a)-(b) above).

        4.    Dividends and Other Distributions.    Any holder of shares of the Executive Stock shall be entitled to receive all dividends and other distributions paid with respect to such shares, provided that any such dividends or other distributions will be subject to the same vesting requirements as the underlying Executive Stock and shall be paid at the time the Executive Stock becomes vested pursuant to Section 2. If any dividends or distributions are paid in shares of common stock or any other equity interests of the Company, such shares or equity interests shall be deposited with the Company and shall be subject to the same restrictions on transferability and forfeitability as the Executive Stock with respect to which they were paid.
