Item 14.    Indemnification of Directors and Officers.

        The Registrant is incorporated under the laws of the State of Delaware. Section 145 ("Section 145") of the Delaware General Corporation Law, as the same exists or may hereafter be amended (the "DGCL"), provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reasons of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation's best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be liable to the corporation. Where an officer, director, employee or agent is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

        Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

II-1

        The Registrant's certificate of incorporation will provide that to the fullest extent permitted by the DGCL, none of the Registrant's directors shall be liable to it or its stockholders for monetary damages for a breach of fiduciary duty. In addition, the Registrant's certificate of incorporation will provide for indemnification of any person who was or is made, or threatened to be made, a party to or is involved in any action, suit or other proceeding, whether, civil, criminal, administrative or investigative, because of his or her status as a director or officer of the Registrant, or service at the request of the Registrant as a director or officer of another corporation, as a partner or officer of a partnership, as a member or officer of a limited liability company, as a principal or officer of a joint venture, as a trustee or officer of a trust or in any comparable capacity in any other enterprise, including service with respect to an employee benefit plan, to the fullest extent authorized under the DGCL against all expenses, liabilities and losses actually and reasonably incurred or suffered by such person in connection therewith. Further, all of the directors and officers of the Registrant are covered by insurance policies maintained and held in effect by the Registrant against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act.

Item 15.    Recent Sales of Unregistered Securities.

        During the last three years, the Registrant has issued securities in the following transactions, each of which was exempt from the registration requirements of the Securities Act. No underwriters were involved in any of the below-referenced sales of securities. The historical share data set forth in this section has not been adjusted to reflect the stock split that is expected to be effected prior to the completion of this offering.

        During the last three years, the Registrant (or its predecessor) has issued the following securities without registration under the Securities Act of 1933:

        (1)   The Registrant was incorporated under the laws of the State of Delaware on September 27, 2006, and in connection therewith issued 100 shares of common stock to GT Solar Incorporated for an aggregate consideration of $100.00. This issuance was made without registration under the Securities Act in reliance upon Section 4(2) thereof.

        (2)   On September 28, 2006, the Registrant entered into the Agreement and Plan of Merger with Solar Incorporated (the "Operating Company") and GT Solar Merger Corp., a newly formed wholly owned subsidiary of the Registrant, pursuant to which GT Solar Merger Corp. was merged with and into the Operating Company, with the Operating Company continuing as the surviving corporation in the merger (the "Reorganization Merger"). In the Reorganization Merger, each outstanding share of common stock of the Operating Company was converted into one share of common stock of the Registrant, and each outstanding option to acquire a share of common stock of the Operating Company was converted into an option to acquire one share of common stock of the Registrant. As a result of the Reorganization Merger, the Registrant issued 8,370,000 shares of common stock. Immediately following, and as a result of, the Reorganization Merger, the Operating Company became a wholly owned direct subsidiary of the Registrant, and the Registrant became a wholly-owned direct subsidiary of GT Solar Holdings, LLC. This issuance was made without registration under the Securities Act in that the Reorganization Merger did not involve a "sale" of securities for purposes of Section 2(3) of the Securities Act. To the extent that the Reorganization Merger was deemed to involve a "sale," such sale was not subject to the registration requirements of the Securities Act under Section 4(2) thereof.

        (3)   In July 2006, the Operating Company granted options to purchase 195,840 shares of its common stock to certain executives, employees, directors and consultants. These option grants were made in the ordinary course of business and did not involve any cash payment from the optionees. The grant of options did not involve a "sale" of securities for purposes of Section 2(3) of the Securities Act and were otherwise made in reliance upon Rule 701 under the Securities Act. Following the

II-2

Reorganization Merger, these options were converted into options exercisable for shares of the Registrant's common stock in accordance with the terms of such options.

        (4)   In December 2007 and January 2008, the Registrant granted options to purchase 187,331 shares of its common stock to certain executives, employees, directors and consultants and 5,000 shares of restricted stock to one executive. The option grants were made in the ordinary course of business and did not involve any cash payment from the optionees. The grant of options did not involve a "sale" of securities for purposes of Section 2(3) of the Securities Act and were otherwise made in reliance upon Rule 701 under the Securities Act. The cash paid for the restricted stock was equal to their par value of $0.01 per share. The issuance of restricted stock was made without registration under the Securities Act in reliance upon Rule 701 thereof.

        (5)   In June 2008, the Registrant granted restricted stock units representing 9,288 shares of its common stock to certain employees and directors. The restricted stock unit grants were made in the ordinary course of business and did not involve any cash payment from the recipient thereof. The issuance of restricted stock units was made without registration under the Securities Act in reliance upon Rule 701 thereof.

Item 16.    Exhibits and Financial Statement Schedules.

Exhibits.

        The attached Exhibit Index is incorporated by reference herein.

Financial Statement Schedules.

        All schedules for which provision is made in the applicable accounting regulations of the Commission are not required under the related instructions, are inapplicable or not material, or the information called for thereby is otherwise included in the financial statements and therefore has been omitted.

Item 17.    Undertakings.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

        The undersigned Registrant hereby undertakes that:

        (1)   For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

        (2)   For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement

II-3

relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (3)   For the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

        (4)   For the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

A.

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;



B.

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;



C.

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and



D.

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

        The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreements certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

The Firm Securities and the Optional Securities are herein collectively called the "Offered Securities".

        2.    Representations and Warranties of the Company and the Selling Stockholder.    (a) The Company represents and warrants to, and agrees with, the several Underwriters and the Selling Stockholder that:

The Selling Stockholder agrees to sell to the Underwriters the number of shares of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased from the Selling Stockholder for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter's name bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Company and the Selling Stockholder.

        5.    Certain Agreements of the Company and the Selling Stockholder.    The Company agrees with the several Underwriters and the Selling Stockholder that:

        (a)    Additional Filings.    Unless filed pursuant to Rule 462(c) as part of the Additional Registration Statement in accordance with the next sentence, the Company will file the Final Prospectus, in a form approved by the Representatives, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Representatives (which consent shall not be unreasonably delayed or withheld), subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Company will advise the Representatives promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Representatives of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Securities under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Company will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Representatives.

        (b)    Filing of Amendments: Response to Commission Requests.    The Company will promptly advise the Representatives of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such amendment or supplementation without the Representatives' consent; and the Company will also advise the Representatives promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and (v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

        (c)    Continued Compliance with Securities Laws.    If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Representatives, an amendment or supplement which will

12

correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives' consent to, nor the Underwriters' delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

        (d)    Rule 158.    As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its security holders an earnings statement covering a period of at least 12 months beginning after the Effective Date of the Initial Registration Statement (or, if later, the Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, "Availability Date" means the day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time on which the Company is required to file its Form 10-Q for such fiscal quarter except that, if such fourth fiscal quarter is the last quarter of the Company's fiscal year, "Availability Date" means the day after the end of such fourth fiscal quarter on which the Company is required to file its Form 10-K.

        (e)    Furnishing of Prospectuses.    The Company will furnish to the Representatives four copies of each Registration Statement (two of which will be photocopies of such signed Registration Statement and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives reasonably request. The Final Prospectus shall be so furnished on or prior to 10:00 P.M., New York time, on the business day following the execution and delivery of this Agreement. All other such documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

        (f)    Blue Sky Qualifications.    The Company will arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives reasonably request and will continue such qualifications in effect so long as required for the distribution; provided, however that the Company shall not be required to qualify to do business, consent to service of process or become subject to taxation in any jurisdiction in which it has not already done so.

        (g)    Reporting Requirements.    During the period of 3 years hereafter, the Company will furnish, upon request, to the Representatives and to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year to the extent such a report is prepared and mailed to Stockholders for such year; and the Company will furnish to the Representatives upon request (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request subject to the execution of a customary confidentiality agreement (with respect to non-public information). However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and files reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR"), it will not be required to furnish such reports or statements to the Underwriters.

        (h)    Payment of Expenses.    The Company agrees with the several Underwriters that the Company will pay all expenses incident to the performance of the obligations of the Company under this Agreement, including but not limited to any filing fees and other expenses (including the fees and disbursements of counsel to the Underwriters) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto, costs and expenses related to the review by the Financial Industry Regulatory Authority of the Offered

        (i)    Absence of Manipulation.    The Company and the Selling Stockholder will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

        (j)    Restriction on Sale of Securities by Company.    For the period specified below (the "Lock-Up Period"), the Company will not, directly or indirectly, take any of the following actions with respect to its Securities or any securities convertible into or exchangeable or exercisable for any of its Securities ("Lock-Up Securities"): (i) offer, sell, issue, contract to sell, pledge or otherwise dispose of Lock-Up Securities, (ii) offer, sell, issue, contract to sell, contract to purchase or grant any option, right or warrant to purchase Lock-Up Securities, (iii) enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of Lock-Up Securities, (iv) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in Lock-Up Securities within the meaning of Section 16 of the Exchange Act or (v) file with the Commission a registration statement under the Act relating to Lock-Up Securities other than a Form S-8 with respect to securities described in clause (B) below, or publicly disclose the intention to take any such action, without the prior written consent of the Representatives, except for (A) the issuance of Lock-Up Securities pursuant to the exercise of any stock options outstanding on the date hereof, (B) the issuance of any stock option or other equity security to any employee, director or officer under any employee benefit plan existing on the date hereof and as described in the General Disclosure Package and the Prospectus or (C) the issuance of Lock-Up Securities in connection with the Company's or any of its subsidiaries' acquisition of, or merger or consolidation with, any other corporation or business entity; provided that in the case of clause (C), that such issuance shall not be greater than 10% of the Securities outstanding on the date of such issuance and the recipients of such Lock-Up Securities agree to be bound by a lockup letter in the form executed by directors, officers and the Selling Stockholder pursuant to Section 7(i) hereof. The initial Lock-Up Period will commence on the date hereof and continue for 180 days after the date hereof or such earlier date that the Representatives consent to in writing; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the materials news or material event, as applicable, unless the Representatives waive, in writing, such extension. The Company will provide the Representatives with notice of any announcement described in clause (2) of the preceding sentence that gives rise to an extension of the Lock-Up Period.

14

        6.    Free Writing Prospectuses.    The Company and Selling Stockholder represent and agree that, unless they obtain the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a "free writing prospectus," as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a "Permitted Free Writing Prospectus." The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an "issuer free writing prospectus," as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that is has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

        7.    Conditions of the Obligations of the Underwriters.    The obligations of the several Underwriters to purchase and pay for the Firm Securities on the First Closing Date and the Optional Securities to be purchased on each Optional Closing Date will be subject to the accuracy of the representations and warranties of the Company and the Selling Stockholder herein (as though made on such Closing Date), to the accuracy of the statements of Company officers made in any certificates delivered pursuant to the provisions hereof, to the performance by the Company and the Selling Stockholder of their respective obligations hereunder and to the following additional conditions precedent:

        (b)    Indemnification of Underwriters by Selling Stockholder.    The Selling Stockholder will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an "Indemnified Party"), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to the above as such expenses are incurred; provided, however, that the Selling Stockholder shall be liable only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in any Registration Statement, any Statutory Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus in reliance upon and in conformity with information relating to the Selling Stockholder furnished to the Company by or on behalf of the Selling Stockholder expressly for use therein; and provided, further, that the liability under this subsection of the Selling Stockholder shall be limited to an amount equal to the aggregate net proceeds after underwriting commissions and discounts, but before expenses, to the Selling Stockholder from the sale of Offered Securities sold by the Selling Stockholder hereunder.

        (d)    Actions against Parties; Notification.    Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action

18

and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

        (e)    Contribution.    If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Stockholder or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and the Selling Stockholder shall not be required to contribute any amount in excess of the aggregate net proceeds after underwriting commissions and discounts, but before expenses, to the Selling Stockholder from the sale of Offered Securities sold by the Selling Stockholder hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(e).

        9.    Default of Underwriters.    If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company and the Selling Stockholder for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting

19

Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives, the Company and the Selling Stockholder for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section.

If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the obligations of the Company and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

        (a)    No Other Relationship.    The Representatives have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company or the Selling Stockholder, on the one hand, and the Representatives, on the other, has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or is advising the Company or the Selling Stockholder on other matters;

        (d)    Waiver.    The Company and the Selling Stockholder waive, to the fullest extent permitted by law, any claims they may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Representatives shall have no liability (whether direct or indirect) to the Company or the Selling Stockholder in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

        16.    Applicable Law.    This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company and the Selling Stockholder each agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and the Selling Stockholder and may be enforced in any other courts to the jurisdiction of which the Company or the Selling Stockholder is or may be subject, by suit upon such judgment.

SCHEDULE C

        The Representatives shall have received letters, dated, respectively, the date hereof and the First Closing Date, of Ernst & Young LLP confirming that they are a registered public accounting firm and independent public accountants within the meaning of the Securities Laws to the effect that:

(i)

in their opinion the audited consolidated financial statements by them and included in the Registration Statements comply as to form in all material respects with the applicable accounting requirements of the Securities Act of 1933 and the related rules and regulations adopted by the SEC;



(ii)

they have read the latest unaudited monthly consolidated financial statements of the Company and its consolidated subsidiaries made available by the Company and the minutes of the meetings of the stockholders, Board of Directors and committees of the Board of Directors of the Company; and have made inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its consolidated subsidiaries as to whether the unaudited monthly financial statements are stated on a basis substantially consistent with that of the audited consolidated financial statements included in the Registration Statement and General Disclosure Package; and on the basis thereof, nothing came to their attention which caused them to believe that:



(A)

with respect to the period subsequent to the date of the most recent audited consolidated financial statements included in the General Disclosure Package, at a specified date at the end of the most recent month, there was any increase in the long-term debt of the Company and its consolidated subsidiaries, or any decrease in stockholders' equity or any change in the consolidated capital stock of the Company and its consolidated subsidiaries or any decrease in the net current assets of the Company and its consolidated subsidiaries, as compared with the amounts shown on the latest balance sheet included in the Registration Statement; or for the period from the day after the date of the most recent audited consolidated financial statements for such entities included in the General Disclosure Package to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenue, or in the total or per share amounts of consolidated net income of the Company and its consolidated subsidiaries, except for such changes, increases or decreases set forth in such letter which the Registration Statement discloses have occurred or may occur;



(iii)

With respect to any period as to which officials of the Company have advised that no consolidated financial statements as of any date or for any period subsequent to the specified date referred to in (ii)(A) above are available, they have made inquiries of certain officials of the Company who have responsibility for the financial and accounting matters of the Company and its consolidated subsidiaries as to whether, at a specified date not more than three business days prior to the date of such letter, there were any increases in the short-term debt or long-term debt of the Company and its consolidated subsidiaries, or any decrease in stockholders' equity or any change in the consolidated capital stock of the Company and its consolidated subsidiaries or any decreases in the net current assets of the Company and its consolidated subsidiaries, as compared with the amounts shown on the most recent balance sheet for such entities included in the Registration Statement; or for the period from the day after the date of the most recent unaudited monthly consolidated financial statements of the Company and its consolidated subsidiaries made available by the Company to such specified date, there were any decreases, as compared with the corresponding period in the preceding year, in revenue or in the total or per share amounts of consolidated net income of the Company and its consolidated subsidiaries and, on the basis of such inquiries and the review of the minutes described in paragraph (ii) above, nothing came to their attention which caused

26

them to believe that there was any such change, increase, or decrease, except for such changes, increases or decreases that the Registration Statement discloses have occurred or may occur; and

(iv)

they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial and statistical information contained in the Registration Statements, and the General Disclosure Package (in each case to the extent that such dollar amounts, percentages and other financial and statistical information are derived from the general accounting records of the Company and its subsidiaries or are derived directly from such records by analysis or computation) with the results obtained from inquiries, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial and statistical information to be in agreement with such results.

        For purposes of this Schedule, if the Effective Time of the Additional Registration Statement is subsequent to the execution and delivery of this Agreement, "Registration Statements" shall mean the Initial Registration Statement and the Additional Registration Statement as proposed to be filed shortly prior to its Effective Time.

        Section. 2    Other Offices.    The Corporation may also have offices at such other places, both within and without the State of Delaware, as the Board of Directors may from time to time determine or the business of the Corporation may require.

ARTICLE II
MEETINGS OF STOCKHOLDERS

        Section. 1    Place of Meetings.    The Board of Directors may designate any place, either within or without the State of Delaware, as the place of meeting for any annual meeting or for any special meeting.

        Section. 2    Annual Meeting.    An annual meeting of stockholders shall be held each year and stated in a notice of meeting or in a duly executed waiver thereof. The date, time and place of such meeting shall be determined by the Chairman of the Board of Directors; provided that if the Chairman does not act, the Board of Directors shall determine the date, time and place of such meeting. At such annual meeting, the stockholders shall elect, by a plurality vote, a Board of Directors and transact such other business as may properly be brought before the meeting.

        Section. 3    Special Meetings.    Special meetings of the stockholders may only be called in the manner provided in the Corporation's certificate of incorporation as then in effect (the "Certificate of Incorporation").

        Section. 4    Notice of Meetings.    Whenever stockholders are required or permitted to take action at a meeting, written notice of each annual and special meeting of stockholders stating the date, time and place of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given to each stockholder of record entitled to vote thereat not less than thirty (30) nor more than sixty (60) days before the date of the meeting. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. Notice shall be given personally or by mail and, if by mail, shall be sent in a postage prepaid envelope, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. Notice by mail shall be deemed given at the time when the same shall be deposited in the United States mail, postage prepaid. Notice of any meeting shall not be required to be given to any person who attends such meeting, except when such person attends the meeting in person or by proxy for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened, or who, either before or after the meeting, shall submit a signed written waiver of notice, in person or by proxy. Neither the business to be transacted at, nor the purpose of, an annual or special meeting of stockholders need be specified in any written waiver of notice.

        Section. 5    List of Stockholders.    The officer having charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, showing the address of and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting or (b) during ordinary business hours, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

        Section. 6    Quorum; Adjournments.    The holders of a majority of the voting power of the issued and outstanding stock of the Corporation entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of stockholders, except as otherwise provided by statute or by the Certificate of Incorporation. If, however, such quorum shall not be present or represented by proxy at any meeting of stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, shall have the power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented by proxy. At such adjourned meeting at which a quorum shall be present or represented by proxy, any business may be transacted which might have been transacted at the meeting as originally called. If the adjournment is for more than thirty (30) days, or, if after adjournment a new record date is set, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

        Section. 7    Organization.    At each meeting of stockholders, the Chairman of the Board of Directors, if one shall have been

2

elected, or, in his absence or if one shall not have been elected, the chief executive officer shall act as chairman of the meeting.

        Section. 8    Order of Business.    The order of business at all meetings of the stockholders shall be as determined by the chairman of the meeting.

        Section. 9    Voting.    Except as otherwise provided by the Certificate of Incorporation, the General Corporation Law of the State of Delaware or the certificate of designations relating to any outstanding class or series of Preferred Stock, each stockholder of the Corporation shall be entitled at each meeting of stockholders to one (1) vote for each share of capital stock of the Corporation standing in his name on the record of stockholders of the Corporation:

(a)

on the date fixed pursuant to the provisions of Section 13 of this Article II of these Bylaws as the record date for the determination of the stockholders who shall be entitled to notice of and to vote at such meeting; or



(b)

if no such record date shall have been so fixed, then at the close of business on the day next preceding the day on which notice thereof shall be given, or, if notice is waived, at the close of business on the date next preceding the day on which the meeting is held.

Each stockholder entitled to vote at any meeting of stockholders may authorize another person or persons to act for him by a proxy which is in writing or transmitted as permitted by law, including, without limitation, electronically, via telegram, internet, interactive voice response system, or other means of electronic transmission executed or authorized by such stockholder or his attorney-in-fact, but no proxy shall be voted after three (3) years from its date, unless the proxy provides for a longer period. Any such proxy shall be delivered to the secretary of the meeting at or prior to the time designated in the order of business for so delivering such proxies. Any proxy transmitted electronically shall set forth information from which it can be determined by the secretary of the meeting that such electronic transmission was authorized by the stockholder. When a quorum is present at any meeting, the vote of the holders of a majority of the voting power of the issued and outstanding stock of the Corporation entitled to vote thereon, present and voting, in person or represented by proxy, shall decide any question brought before such meeting, unless the question is one upon which by express provision of statute or of the Certificate of Incorporation or of these Bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such question. Unless required by statute, or determined by the chairman of the meeting to be advisable, the vote on any question need not be by ballot. On a vote by ballot, each ballot shall be signed by the stockholder voting, or by his proxy, if there be such proxy, and shall state the number of shares voted and the number of votes to which each share is entitled.

        Section. 10    Inspectors.    The Board of Directors may, in advance of any meeting of stockholders, appoint one or more inspectors to act at such meeting or any adjournment thereof. If any of the inspectors so appointed shall fail to appear or act, the chairman of the meeting shall, or if inspectors shall not have been appointed, the chairman of the meeting may, appoint one or

3

more inspectors. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability. The inspectors shall determine the number of shares of capital stock of the Corporation outstanding and the voting power of each, the number of shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the results, and do such acts as are proper to conduct the election or vote with fairness to all stockholders. On request of the chairman of the meeting, the inspectors shall make a report in writing of any challenge, request or matter determined by them and shall execute a certificate of any fact found by them. No director or candidate for the office of director shall act as an inspector of an election of directors. Inspectors need not be stockholders.

        Section. 11    Advance Notice of Director Nominations.

        (a)    Nomination of Persons for Elections as Directors.

(i)

Unless otherwise required by applicable law, the Certificate of Incorporation or any instrument of designation of any series of preferred stock of the Corporation with respect to the right of holders of preferred stock of the Corporation, only persons who are nominated in accordance with the following procedures shall be eligible for election as directors of the Corporation. Nominations of persons for election to the Board of Directors may be made at any annual meeting of stockholders of the Corporation or at any special meeting of stockholders of the Corporation called for the purpose of electing directors and must be:



(A)

expressly specified in the notice of meeting (or any supplement or amendment thereto) given by or at the direction of the Board of Directors;



(B)

otherwise made by or at the direction of the Board of Directors; or



(C)

otherwise properly made by any stockholder of the Corporation who (i) is a stockholder of record at the time of giving of notice provided for in this Bylaw, on the record date for the meeting and at the time of the meeting (ii) is entitled to vote at the meeting and (iii) complies with the notice procedures set forth in this Bylaw as to such nomination.

        (b)    Timely Notice of Nomination.

(i)

For a nomination to be properly made by a stockholder pursuant to Section 11(a)(i)(C) of this Article II, the stockholder must, in addition to any other applicable requirements, have given timely

4

notice thereof in writing to the Secretary. To be timely, a stockholder's notice must be received by the Secretary at the principal executive offices of the Corporation by the close of business:

(A)

in the case of an annual meeting, no fewer than ninety (90) nor more than one hundred twenty (120) days prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is not within thirty (30) days before or sixty (60) days after such anniversary date, to be timely a stockholder's notice must be received by the Secretary by the close of business on the tenth (10^th) day following the day on which a public announcement (as defined below) with respect to the date of such meeting is first made by the Corporation; and



(B)

in the case of a special meeting called for the purpose of electing directors, no fewer than ninety (90) nor more than one hundred twenty (120) days prior to the date of such meeting; provided, however, that if the first public announcement of the date of such special meeting is less than one hundred (100) days prior to the date of such special meeting, to be timely a stockholder's notice must be received by the Secretary by the close of business on the tenth (10^th) day following the day on which a public announcement with respect to the date of such meeting is first made by the Corporation.

        In no event shall any adjournment or postponement of a meeting or the announcement thereof commence a new time period (or extend any time period) for the giving of a stockholder's notice as described above. Notwithstanding the foregoing, in the event that the number of directors to be elected to the Board of Directors at any annual meeting is increased and the first public announcement of such increase is less than one hundred (100) days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice required by this Bylaw shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be received by the Secretary at the principal executive offices of the Corporation by the close of business on the tenth (10^th) day following the day on which a public announcement with respect to such elections is first made by the Corporation.

        (c)    Proper Form of Notice of Director Nomination.

Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

13

meeting, a majority of the directors present at such meeting shall elect one of their members to so preside. A majority of the total number of directors then in office shall constitute a quorum for the transaction of business. Unless by express provision of an applicable law, the Certificate of Incorporation or these Bylaws a different vote is required, the vote of a majority of directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

        Section. 7    Committees.    The Board of Directors (i) may, by resolution passed by a majority of the entire Board of Directors, designate one or more committees, including an executive committee, consisting of one or more of the directors of the Corporation, and (ii) shall during such period of time as any securities of the Corporation are listed on the Nasdaq Global Market (the "Nasdaq"), by resolution passed by a majority of the entire Board of Directors, designate all committees required by the rules and regulations of the Nasdaq. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Except to the extent restricted by applicable law or the Certificate of Incorporation, each such committee, to the extent provided in the resolution creating it, shall have and may exercise all the powers and authority of the Board of Directors. Each such committee shall serve at the pleasure of the Board of Directors as may be determined from time to time by resolution adopted by the Board of Directors or as required by the rules and regulations of the Nasdaq, if applicable. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors upon request.

        Section. 8    Committee Rules.    Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. Unless otherwise provided in such a resolution, in the event that a member and that member's alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member.

        Section. 9    Communications Equipment.    Members of the Board of Directors or any committee thereof may participate in and act at any meeting of such board or committee through the use of a conference telephone or other communications equipment by means of which all persons participating in the meeting can hear and speak with each other, and participation in the meeting pursuant to this section shall constitute presence in person at the meeting.

        Section. 10    Action by Written Consent.    Unless otherwise restricted by the Certificate of Incorporation, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of such board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the board or committee.

ARTICLE V
CERTIFICATES OF STOCK

        Section. 1    Form.    The shares of stock of the Corporation may be represented by certificates or may be in uncertificated form. Every holder of stock represented by a certificate and, upon request, every holder of uncertificated shares shall be entitled to have a certificate, signed by, or in the name of the Corporation by (i) the chairman of the board, the chief executive officer, the president or a vice president and the chief financial officer, the treasurer or an assistant treasurer or the secretary or an assistant secretary of the Corporation, or (ii) any two officers designated by the Board of Directors, certifying the number of shares owned by such holder in the Corporation. If such a certificate is countersigned (i) by a transfer agent or an assistant transfer agent other than the Corporation or its employee or (ii) by a registrar, other than the Corporation or its employee, the signature of any such chairman of the board, chief executive officer, president, vice president, chief financial officer, treasurer, assistant treasurer, secretary or assistant secretary may be facsimiles. In case any officer or officers who have signed, or whose facsimile signature or signatures have been used on, any such certificate or certificates shall cease to be such officer or officers of the Corporation whether because of death, resignation or otherwise before such certificate or certificates have been delivered by the Corporation, such certificate or certificates may nevertheless be issued and delivered as though the person or persons who signed such certificate or certificates or whose facsimile signature or signatures have been used thereon had not ceased to be such officer or officers of the Corporation.

17

All certificates for shares shall be consecutively numbered or otherwise identified. The name of the person to whom the shares represented thereby are issued, with the number of shares and date of issue, shall be entered on the books of the Corporation. Shares of stock of the Corporation represented by a certificate shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder's attorney duly authorized in writing, upon surrender to the Corporation of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates and record the transaction on its books. Uncertificated shares of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder's attorney duly authorized in writing, upon presentment of proper evidence of succession, assignation or authority to transfer in accordance with the customary procedures for transferring shares in uncertificated form. The Board of Directors may appoint a bank or trust company organized under the laws of the United States or any state thereof to act as its transfer agent or registrar, or both in connection with the transfer of any class or series of securities of the Corporation. The Board of Directors may make such additional rules and regulations, not inconsistent with these Bylaws, as it may deem expedient concerning the issue, transfer and registration of certificates for shares of stock of the Corporation.

        Section. 2    Lost Certificates.    The Corporation may issue or direct a new certificate or certificates to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the loss, theft or destruction of any such certificate or the issuance of such new certificate.

        Section. 3    Registered Stockholders.    Prior to the surrender to the Corporation of the certificate or certificates for a share or shares of stock with a request to record the transfer of such share or shares, the Corporation may treat the registered owner as the person entitled to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner.

The loan, guaranty or other assistance may be with or without interest, and may be unsecured, or secured in such manner as the Board of Directors shall approve, including, without limitation, a pledge of shares of stock of the Corporation.

        Section. 7    Voting Securities Owned By Corporation.    Voting securities in any other Corporation held by the Corporation shall be voted by the chief executive officer, unless the Board of Directors specifically confers authority to vote with respect thereto, which authority may be general or confined to specific instances, upon some other person or officer. Any person authorized to vote securities shall have the power to appoint proxies, with general power of substitution.

        Section. 8    Inspection of Books and Records.    The Board of Directors shall have power from time to time to determine to what extent and at what times and places and under what conditions and regulations the accounts and books of the Corporation, or any of them, shall be open to the inspection of the stockholders; and no stockholder shall have any right to inspect any account or book or document of the Corporation, except as conferred by the laws of the State of Delaware, unless and until authorized so to do by resolution of the Board of Directors or of the stockholders of the Corporation.

        This Confidentiality Agreement (this "Agreement") is made and entered into as of the 7th day of May, 2008 by and between GT Solar International, Inc. and its subsidiaries and affiliates ("GT Solar") and the undersigned, a prospective member of the Board of Directors of GT Solar (the "Recipient").

WITNESSETH:

        WHEREAS, the Recipient desires to receive certain information from GT Solar to assist Recipient in evaluating Recipient's prospective service on the Board of Directors of GT Solar; and

        WHEREAS, in connection therewith, GT Solar will be disclosing to the Recipient certain confidential information regarding GT Solar's business, which information GT Solar desires to protect;

        NOW, THEREFORE, in consideration of the covenants and obligations herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

        2.     Confidentiality.    The Recipient, for himself or herself and each of Recipient's agents, shall be subject to the following obligations with respect to the Confidential Information:

to keep the Confidential Information confidential and secret, and not, without the prior written consent of GT Solar, to disclose directly or indirectly the Confidential Information to any third party,



(b)

not to use the Confidential Information directly or indirectly for any purpose other than in connection with evaluating Recipient's prospective service as a Board Member of GT Solar; and



(c)

otherwise to exercise at least the same degree of care with respect to the Confidential Information as the Recipient uses in handling his or her own or proprietary information, except that the foregoing obligation of confidentiality and non-use shall not apply to:



(1)

information which at the time of disclosure is already in the public domain;



(2)

information which after disclosure hereunder becomes part of the public domain by publication or otherwise through no act or fault of the Recipient;



(3)

information which can be proven to have been known to the Recipient prior to the date hereof and not obtained or derived in contravention of any confidentiality obligation in favor of GT Solar;



(4)

information obtained from a third party in lawful possession of such information who is not under a confidentiality obligation to GT Solar; or



(5)

information disclosed by the Recipient's pursuant to applicable law, governmental regulation or legal process: provided, however, the Recipient shall give GT Solar timely

1

notice of the service of a subpoena or other process so that GT Solar may seek a protective order or other legal remedy to prevent disclosure, shall disclose only such information as is required by such process, and shall take reasonable steps to have the confidentiality of such information protected to the extent possible under such legal process; and

(d)

not to circumvent GT Solar, directly or indirectly, regarding any potential business opportunity with respect to any matters or projects on which Recipient is working with or for, or learns of through, GT Solar.

        Upon the written request of GT Solar at any time, the Recipient shall account for and immediately return to GT Solar all tangible embodiments of Confidential Information.

        5.     Governing Law.    This Agreement shall be governed by the laws of the State of Delaware, without regard to the provisions governing conflicts of law, and all rights and remedies shall be construed and interpreted in accordance therewith and the federal or state courts of which shall have exclusive jurisdiction over any disputes arising hereunder.

        6.     No Warranty.    The Recipient hereby acknowledges that neither GT Solar nor any of its respective agents, affiliates or assigns makes any representations or warranties whatsoever concerning the accuracy, completeness or correctness of the Confidential Information supplied hereunder, nor is any such representation or warranty to be implied.

        7.     Miscellaneous.    This Agreement represents the entire agreement between the parties with respect to the subject matter hereof and may be executed in one or more separate counterparts, all of which shall constitute one and the same Agreement and may be amended only in writing executed by both parties. The failure of either party to enforce or insist upon compliance with any of the terms or conditions of this Agreement, the waiver of any term or condition of this Agreement or the granting of an extension of time for performance, shall not constitute the permanent waiver of any term or condition of this Agreement and this Agreement and each of its provisions shall remain at all times in full force and effect. All notices hereunder shall be in writing and mailed, faxed or otherwise delivered to the last address of the recipient known to the sender, and shall be effective upon the fifth (5th) business day after posting, if by first class U.S. mail.

Exhibit 10.41

GT SOLAR INTERNATIONAL, INC.

RESTRICTED STOCK UNIT AGREEMENT

        THIS RESTRICTED STOCK UNIT AGREEMENT (this "Agreement") is made as of [                        ], 2008, by and between GT Solar International, Inc., a Delaware corporation (the "Company"), and [                        ] ("Director"), in accordance with the 2008 Equity Incentive Plan of the Company, as the same may be amended from time to time (the "Plan").

        The Company and Director desire to enter into an agreement pursuant to which the Company shall grant to Director [                        ] restricted stock units (the "RSUs") under the Plan. Each RSU shall entitle Director to receive from the Company one share of the Company's common stock, par value $.01 per share ("Common Stock") for each RSU granted hereunder that becomes vested under the terms described herein and in the Plan. All of such shares of Common Stock that may hereafter be delivered to Director pursuant to this Agreement are referred to herein as "Director Stock." The issuance of shares of the Director Stock to Director 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 7 of this Agreement.

        The parties hereto agree as follows:

1.

Incorporation by Reference; Plan Document Receipt.    This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time unless such amendments are expressly intended not to apply to the award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were expressly set forth herein. Any capitalized term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan. Director hereby acknowledges receipt of a true copy of the Plan and that Director has read the Plan carefully and fully understands its content. In the event of a conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control.

2.

Grant of the RSUs.

(a)

The Company hereby grants to Director, as of the date hereof, [                        ] RSUs, subject to the terms and conditions hereunder. Director agrees and understands that nothing contained in this Agreement provides, or is intended to provide, Director with any protection against potential future dilution of Director's stockholder interest in the Company for any reason. Director shall not have the rights of a stockholder in respect of the shares of Common Stock underlying these RSUs until such Common Stock is delivered to the Participant in accordance with Section 4.

(b)

The grant of the RSUs by the Company is subject to Director's execution and delivery of the attached Non-Competition, Non-Disclosure, Proprietary Information and Patent and Invention Assignment Agreement between Director and the Company (or, at the discretion of the Board, a similar agreement containing such terms as the Board, or a duly designated committee thereof, shall determine) (the "Director Non-Disclosure Agreement"), and these RSUs and all shares of the Director Stock shall be subject to the terms and conditions of the Director Non-Disclosure Agreement.

(c)

In connection with the receipt of the RSUs and the delivery of any Director Stock hereunder, Director represents and warrants to, and agrees with, the Company that:

(i)

The RSUs and the Director Stock to be acquired by Director pursuant to this Agreement shall be acquired for Director'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 RSUs and the Director Stock shall not be disposed of in contravention of the Securities Act or any applicable state securities laws.

(ii)

Director acknowledges that the RSUs and the Director Stock have 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)

Director is a director on the Board, is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Director Stock.



(iv)

Director is able to bear the economic risk of holding the Director Stock for an indefinite period of time because the RSUs and the Director Stock have 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)

Director is an "accredited investor" as such term is defined in Rule 501 under the Securities Act.



(vi)

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



(vii)

This Agreement constitutes the legal, valid and binding obligation of Director, enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by Director do not and shall not conflict with, violate or cause a breach of any agreement, contract or instrument to which Director is a party or any judgment, order or decree to which Director is subject.



(viii)

Director 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 Director is a party or by which Director is bound. Director agrees to notify the Board of any matter (including, but not limited to, any potential acquisition by the Company) which, to Director's knowledge, might reasonably be expected to violate or cause a breach of any such agreement.



(ix)

Director is a resident of the State of [                        ].



(x)

Director 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 any RSUs to Director, and as a condition thereto, Director acknowledges and agrees that neither the issuance of the RSUs or the delivery of any Director Stock nor any provision contained herein shall entitle Director to a directorship on the Board and/or on the board of directors of the Subsidiaries, or affect the right of the Company to terminate Director's directorship at any time, with or without cause.



(e)

The Company and Director acknowledge and agree that this Agreement has been executed and delivered, the RSUs have been granted and any Director Stock that may be delivered hereunder will be delivered, in connection with and as a part of the compensation and incentive arrangements between the Company and Director.



(f)

In connection with the issuance of any Director Stock hereunder, Director hereby agrees and acknowledges that all of the shares of the Director Stock are subject in all respects to the terms of this Agreement, the Amended and Restated Stockholders' Agreement (as if Director

2

were an "Employee Stockholder" and as if the shares of the Director Stock were "Covered Shares," as such terms are defined in such agreement), and the Amended and Restated Registration Rights Agreement, each as may be amended from time to time. In addition, Director hereby accepts all the terms and conditions of (i) the Amended and Restated 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 "Employee Stockholder" thereunder, and (ii) the Amended and Restated Registration Rights Agreement. Notwithstanding the foregoing, Director agrees and acknowledges that under no circumstances may any shares of the Director Stock that may be issued hereunder be transferred to any Person except in connection with a Drag Along Transaction (as defined in the Amended and Restated Stockholders' Agreement) pursuant to the Amended and Restated Stockholders' Agreement.

3.

Vesting.

(a)

Except as otherwise provided in this Section 3, the RSUs shall become vested in accordance with the following schedule, if as of each such date Director has continuously served as a director on the Board and/or on the board of directors of the Subsidiaries since the date hereof, such that, subject to the other terms and conditions of this Agreement, all of the RSUs shall be vested on [                                    ]:

Date	Portion of RSUs Vested
[                    ]	[                    ] RSUs
[                    ]	Additional [                    ] RSUs

(b)

Except as otherwise provided in this Section 3, if Director's directorship with the Company and/or its Subsidiaries terminates for any reason (including upon the death or disability of Director prior to the vesting of all or any portion of the RSUs awarded under this Agreement), such unvested portion of the RSUs shall immediately be cancelled and Director (and Director's estate, designated beneficiary or other legal representative) shall forfeit any rights or interests in and with respect to any such RSUs.



(c)

In addition to Sections 3(a)-(b) above, upon a termination of Director's directorship with the Company that also constitutes a "separation from service" within the meaning of Treas. Reg. § 1.409A-3(i)(5) within twelve months following a "Change in Control," as defined below, of the Company (the "Change in Control Termination"), the RSUs shall vest as follows: (A) if the Change in Control Termination occurs on or before [                                    ], [                        ] RSUs shall vest on the date of the Change in Control Termination and (B) if the Change in Control Termination occurs [                                    ], the remaining [                        ] RSUs shall vest. For purposes of this Agreement, (x) the term "Change in Control" means (i) the consummation of any transaction or series of transactions resulting in a Third Party (or group of affiliated third parties) owning, directly or indirectly, securities of the Company possessing the voting power to elect a majority of the members of the Board (whether by merger, consolidation or sale or transfer of the Company's securities) or (ii) the sale, transfer or other disposition of all or substantially all of the business and assets of the Company, whether by sale of assets, merger or otherwise (determined on a consolidated basis) to a Third Party (or group of affiliated third parties), and (y) the term "Third Party" means any person or entity who or which (i) does not own any of the Company's securities as of the date of this Agreement, (ii) is not controlling, controlled by or under common control with any person or entity that owns any of the Company's securities as of the date of this Agreement and (iii) is not the spouse or descendent (by birth or adoption) of any person who directly or indirectly owns or controls any of the Company's securities as of the date of this Agreement. Upon the occurrence of a Change in Control Termination in the time period described in either

3

clause (A) or (B) of the first sentence of this Section 3(c), the Board shall be permitted, in its sole discretion, to cause the Company to pay to Director in substitution for the vesting of Director's RSUs and the delivery of Common Stock to Director under such circumstances and in respect of each share of Common Stock that would otherwise be issuable upon such vesting, cash in an amount per share of Common Stock equal to the price per share payable in the Change in Control in respect of each issued and outstanding share of Common Stock.

4.

Delivery of Common Stock.    Subject to the terms of the Plan, if the RSUs awarded by this Agreement become vested, the Company shall promptly distribute to Director the number of shares of Common Stock equal to the number of the RSUs that so vested; provided that to the extent required by Section 409A of the Code, delivery of shares of Common Stock upon a Participant's "separation from service" within the meaning of Treas. Reg. § 1.409A-1 shall be deferred until the six month anniversary of such separation from service. In connection with the delivery of the shares of Common Stock pursuant to this Agreement, the Participant agrees to execute any documents reasonably requested by the Company and provide therein customary representations and warranties related to the receipt of such shares of Common Stock.

5.

Certificates.    The shares of Director Stock may be in certificated or uncertificated form, as permitted by the Company's Bylaws. Prior to any registered public offering of any Common Stock, the Company shall hold each certificate representing the Director Stock (or shall reflect in its records the uncertificated Director Stock as being held by the Company) until such time as such Director Stock is transferred by Director, other than to a Family Transferee (as defined in the Amended and Restated Stockholders' Agreement), in compliance with the provisions of the Amended and Restated Stockholders' Agreement.

6.

Restructuring Event.    In the event of a stock dividend, stock split or recapitalization or a corporate reorganization in which the Company is a surviving corporation, including without limitation a merger, consolidation, split-up or spin-off or a liquidation or distribution of securities or assets other than cash dividends (a "Restructuring Event"), the number of shares of the Director Stock held by Director may be adjusted by the Board, or a duly designated committee thereof, as it reasonably determines is necessary to reflect such Restructuring Event.

7.

Definitions.

        "Board" means the Company's Board of Directors.

        "Amended and Restated Registration Rights Agreement" means the Amended and Restated Registration Rights Agreement, by and among the Company, GT Solar Holdings, LLC, and the other parties thereto, dated July 1, 2008, as amended from time to time.

        "Amended and Restated Stockholders' Agreement" means the Amended and Restated Employee Stockholders' Agreement of the Company, by and among the Company and the stockholders of the Company, dated July 1, 2008, as amended from time to time.

General Provisions.

(a)

Transferability.    The RSUs shall not be transferable by Director other than by the laws of will or descent. All provisions of this Agreement shall in any event continue to apply to any RSU transferred as permitted by this Section 9(a), and any transferee shall be bound by all provisions of this Agreement as and to the same extent as Director. Any transfer or attempted transfer of any RSUs in violation of any provision of this Agreement or the Amended and Restated Stockholders' Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such RSUs as the owner of such stock for any purpose.

(b)

Withholding Taxes.    The Company shall be entitled to withhold from any amounts due and payable by the Company to Director the amount of any federal, state, local or other tax which, in the opinion of the Company, is required to be withheld in connection with the vesting of the RSUs or the delivery of shares of the Director Stock. To the extent that the amounts available to the Company for such withholding are insufficient, it shall be a condition to the delivery or vesting, as applicable, of such shares of the Director Stock that Director make arrangements satisfactory to the Company for the payment of the balance of such taxes required to be withheld. The Board, upon the written request of Director, in the Board's sole discretion and pursuant to such procedures as it may specify from time to time, may permit Director to satisfy all or part of the tax obligations in connection with the vesting of the RSUs or the delivery of the shares of Director Stock by (a) having the Company withhold otherwise deliverable shares, or (b) delivering to the Company already-owned shares, in each case having a Fair Market Value (as defined in the Plan) equal to the amount sufficient to satisfy such tax obligations, provided such shares have been held by Director for at least six months.

(c)

Severability.    Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this Agreement shall be reformed, construed and

5

enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

(d)

Complete Agreement.    This Agreement, the Plan, those documents expressly referred to herein and therein and other documents of even date herewith embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.



(e)

Counterparts.    This Agreement may be executed in separate counterparts, each of which is deemed to be an original and all of which taken together constitute one and the same agreement.



(f)

Successors and Assigns.    Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be enforceable by Director, the Company and their respective successors and assigns (including subsequent permitted holders of the RSUs or the Director Stock); provided that the rights and obligations of Director under this Agreement shall not be assignable except in connection with a permitted transfer of the Director Stock hereunder.



(g)

Choice of Law.    All questions concerning the construction, validity, enforcement and interpretation of this Agreement and the exhibits hereto shall be governed by, and construed in accordance with, the internal law, and not the law of conflicts, of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.



(h)

Remedies.    Each of the parties to this Agreement shall be entitled to enforce its rights under this Agreement specifically, to recover damages and costs (including reasonable attorney's fees) caused by any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or deposit) in order to enforce or prevent any violations of the provisions of this Agreement.



(i)

Amendment and Waiver.    The provisions of this Agreement may be amended and waived only with the prior written consent of the Company and Director.

Exhibit 10.42

PROPRIETARY RIGHTS AND CONFIDENTIALITY AGREEMENT

        THIS PROPRIETARY RIGHTS AND CONFIDENTIALITY AGREEMENT (this "Agreement") is made as of [                                    ] between GT SOLAR INTERNATIONAL,  INC. on behalf of itself and its affiliates (collectively, the "Company") and the undersigned director ("Director").

        In consideration of Director's engagement as a director of the Company and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto intending to be legally bound agree as follows:

1.     Protection of Confidential Information.

        (a)   Obligation to Maintain Confidentiality.    Director acknowledges and agrees that the continued success of the Company depends upon the use and protection of a large body of confidential and proprietary information. All of such confidential and proprietary information now existing or to be developed in the future will be referred to in this Agreement as "Confidential Information." Confidential Information will be interpreted as broadly as possible to include all information of any sort (whether merely remembered or embodied in a tangible or intangible form) that is (i) related to the Company's current or potential business and (ii) is not generally or publicly known. Confidential Information includes, without limitation, the information, observations and data obtained by Director during the course of his service as a director of the Company concerning the business and affairs of the Company and includes third party confidential information. Therefore, Director agrees that he shall not, at any time during or after his service as a director of the Company, disclose to any unauthorized person or use for his own account any of such Confidential Information without the prior written consent of the Company, unless and to the extent that any Confidential Information (i) becomes generally known to and available for use by the public other than as a result of Director's acts or omissions or (ii) is required to be disclosed pursuant to any applicable law or court order, provided that with respect to clause (ii), Director shall at the earliest practicable date provide a copy of the subpoena or court order to the Company's general counsel. Director agrees to deliver to the Company at the end of his service as a director of the Company, or at any other time upon request, all tools, supplies and Confidential Information, along with all copies.

        (b)   Use of Information of Employers.    During Director's service as a director of the Company, Director is not requested to, and shall not, use or disclose any confidential information of any employer of the Director or any other person to whom Director has an obligation of confidentiality.

        (c)   Additional Acknowledgments.    Director acknowledges and agrees that he has carefully read this Agreement and has given careful consideration to the restraints imposed upon Director by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of Confidential Information of the Company. Director expressly acknowledges and agrees that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical area.

2.     Miscellaneous.

        (a)   No Guarantee.    This Agreement shall not be construed and is not intended by either Director or the Company to be a guarantee, commitment or understanding of Director's continued service as a director of the Company for any period of time.

        (b)   Remedies.    Because Director's services are unique and because Director has access to Confidential Information and Developments, the parties hereto agree that money damages would not be an adequate remedy for any breach of this Agreement. Therefore, in the event of a breach or

1

threatened breach of this Agreement, the Company, in addition to other rights and remedies existing in its favor, shall be entitled to specific performance and/or injunctive or other equitable relief from a court of competent jurisdiction in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

        (c)   Survival.    Director's obligations under this Agreement shall survive termination of Director's service as a director of the Company and shall thereafter be enforceable whether or not such termination is later claimed or found to be wrongful or to constitute or result in a breach of any contract or of any other duty owed or claimed to be owned by the Company to Director.

        (d)   Entire Agreement.    This Agreement supersedes all prior agreements between the Company and Director related to the subject matter hereto, and cannot be modified except in writing signed by the parties hereto.

        (e)   Assignment.    This Agreement shall be binding upon Director and his heirs, successors and legal representatives and shall be binding upon and inure to the benefit of the Company and its successors and assigns. The Company may freely assign this Agreement. Director not assign this Agreement or his rights and obligations hereunder.

        (f)    Governing Law.    This Agreement shall be governed by the laws of the State of Delaware (without reference to conflict of laws provisions).

        (g)   Representations.    Director represents that there is no agreement with any other party that would conflict with his obligations under this Agreement Director represents and warrants that he (i) has read and understands each and every provision of this Agreement, (ii) has had the opportunity to obtain advice from legal counsel of his choice in order to interpret any and all provisions of this Agreement and (iii) has had the opportunity to ask the Company questions about this Agreement and any of such questions he has asked have been answered to his satisfaction.

All existing confidential lists of customers of the Company, and all confidential lists of customers of the Company developed during the course of my employment by the Company, are and shall be the sole and exclusive property of the Company, and that I neither have nor shall have any right, title or interest therein; such lists of customers are and must continue to be confidential; and the Company's present and future business relationship with its customers is and will continue to be of a type which normally continues unless interfered with by others.

E.

As used herein, the period of my employment includes any time during which I may be retained by the Company as an Independent Contractor.

Ownership of Proprietary Information—All Proprietary Information shall be the sole property of the Company and its assigns, and the Company and its assigns shall be the sole owner of all

patents, copyrights, trademarks and other rights in connection therewith. I hereby assign to the Company any rights I may have or acquire in such Proprietary Information. I hereby acknowledge that all Proprietary Information is and must continue to be confidential and that the same is not readily accessible to competitors of the Company. At all times, both during my employment by the Company and after its termination, I will keep in strictest confidence and trust all Proprietary Information and I will not use or disclose any Proprietary Information without the written consent of the Company, except as may be necessary in the ordinary course of performing my duties as an employee of the Company.

I will also promptly disclose to the Company, and the Company hereby agrees to receive all such disclosures in confidence, all other discoveries, developments, designs, improvements, inventions, formulae, processes, techniques, computer programs, strategies, blueprints, know-how and data, whether or not patentable or registerable under copyright or similar statutes, made or conceived or reduced to practice or learned by me, either alone or jointly with others, during the period of my employment for the purpose of determining whether they constitute "Inventions", as defined above.

6.

Ownership of Inventions—All Inventions shall be the sole property of the Company and its assigns, and the Company and its assigns shall be the sole owner of all patents, copyrights, trademarks and other rights in connection therewith. I hereby assign to the Company any rights I may have or acquire in such Inventions. I shall assist the Company in every proper way as to all such Inventions (but at the Company's expense) to obtain and, from time to time, enforce patents, copyrights, trademarks and other rights and protections relating to said Inventions in any and all countries, and to that end, I will execute all documents for use in applying for and obtaining such patents, copyrights, trademarks and other rights and protections on and enforcing such Inventions, as the Company may desire, together with any assignments thereof to the Company or persons designated by it. My obligation to assist the Company in obtaining and enforcing patents, copyrights, trademarks and other rights and protections relating to such Inventions in any and all countries shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after my termination for time actually spent by me at the

Company's request on such assistance. In the event the Company is unable, after reasonable effort, to secure my signature on any document or documents needed to apply for or prosecute any patent, copyright or other right or protection relating to an Invention, for any reason whatsoever, I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney-in-fact, to act for and on my behalf to execute and file any such application or applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyrights or similar protections thereon with the same legal force and effect as if executed by me and I hereby ratify, affirm and approve all such lawfully permitted acts accordingly.

7.

Other Agreements—I represent and warrant that my execution and delivery of this Agreement and the performance of all the terms of this Agreement does not and will not breach any agreement to keep in confidence proprietary information acquired by me in confidence or trust. I have not entered into and shall not enter into any agreement, either written or oral, in conflict herewith.

8.

Use of Confidential Information of Other Persons—I represent that I have not brought and will not bring with me to the Company or use at the Company any materials or documents of an employer or a former employer that are not generally available to the public, unless express written authorization from such employer for their possession and use has been obtained. I also understand that I am not to breach any obligation of confidentiality that I have to any employer or former employer and agree to fulfill all such obligations during the period of my affiliation with the Company.

9.

Restrictive Covenant—I hereby acknowledge and recognize my possession of Proprietary Information and the highly competitive nature of the business of the Company and accordingly agree that, in consideration of the premises contained herein, I will not, during the period of my employment by the Company and in the event that my employment with the Company is terminated for any reason whatsoever and whether such termination be voluntary or involuntary, for a period of three years (3) years following such termination, (i) directly or indirectly engage in any competitive business (defined as a business that designs, develops, manufactures, markets or sells a product, product line or service that competes with any product, product line or service of the Company as they presently exist or as may be in existence or development on the date of termination of my employment with the Company whether such engagement shall be as an employer, officer, director, owner, employee, partner or other participant, (ii) assist others in engaging in any competitive business in the manner described in the foregoing clause (i), or (iii) induce employees of the Company, its affiliates or subsidiaries to terminate their employment with the Company or such affiliate or subsidiary and/or engage in any competitive business. I understand that this Section 9 is not meant to prevent me from earning a living or fostering my career. It does intend, however, to prevent any competitive business from gaining any unfair advantage from my knowledge of Proprietary Information. I understand that by making my new employer aware of the provisions of this Section 9, they can take such action as to avoid my breaching the provisions hereof and to indemnify me in the even of a breach.

10.

Agreement Not to Solicit Customers—During the course of my employment by the Company for a period of three (3) years following the termination of such employment for any reason whatsoever and whether such termination be voluntary or involuntary, I will not, directly or indirectly, as owner, officer, director, stockholder, partner, associate, consultant, manager, advisor, representative, employee, agent, creditor or otherwise, attempt to solicit or in any other way disturb or service any person, firm or corporation that has been a customer account of the Company at any time or times within three (3) years prior to the termination date of my

employment, whether or not I had direct account responsibility for a contact with such customer account.

11.

Remedies—I acknowledge that a remedy at law for any breach or threatened breach of the provisions of this Agreement would be inadequate and, therefore, agree that the Company shall be entitled to injunctive relief in addition to any other available rights and remedies in case of any such breach or threatened breach; provided, however, that nothing contained herein shall be construed as prohibiting the Company from pursuing any other remedies available for any such breach or threatened breach.

12.

Assignment—This Agreement and the rights and obligations of the parties hereto shall bind and inure to the benefit of any successor or successors of the Company, whether by reorganization, merger, consolidation, sale of assets or otherwise, except that neither this Agreement nor any rights or benefits hereunder may be assigned by me.

13.

Interpretation—It is the desire and intent of the parties hereto that the provisions of this Agreement shall be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated to be invalid or unenforceable, such provision shall be deemed amended to delete there from the portion thus adjudicated to be invalid or unenforceable, such deletion to apply only with respect to the operation of such provision in the particular jurisdiction in which such adjudication is made. In addition, if any one or more of the provisions contained in this Agreement shall, for any reason, be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it so as to be enforceable to the extent compatible with the applicable law as it shall then appear.

14.

Notices—Any notice which a party is required or may desire to give pursuant to this Agreement shall be given by personal delivery or registered or certified mail, return receipt requested, addressed to the Employee at the address of the Employee of record with the Company and addressed to the Company at its principal office, or at such other place as either party may, from time to time, designate in writing. The date of personal delivery or the date of mailing any such notice shall be deemed to be the date of delivery thereof.

15.

Waivers—If either party shall waive any breach of any provision of this Agreement, her or it shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement.

16.

Headings—The headings of the sections hereof are inserted for convenience only and shall not be deemed to constitute a part hereof nor to affect the meaning hereof.

17.

Governing Law—This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New Hampshire with respect to contracts made and to be performed wholly therein.

18.

No Employment Agreement—I acknowledge that this Agreement does not constitute an employment agreement and agree that this Agreement shall be binding upon me regardless of whether or not my employment shall continue for any length of time hereafter and whether or not my employment is terminated for any reason whatsoever by either the Company or me or both.

19.

Complete Agreement; Amendments: Prior Agreements—The foregoing is the entire agreement of the parties with respect to the subject matter hereof and may not be amended,

supplemented, canceled or discharged except by written instrument executed by both parties hereto. This Agreement supersedes any and all prior agreements between the parties hereto with respect to the matters covered hereby.
