ARTICLE III
CAPITAL CONTRIBUTIONS

        3.1 Shareholders.    

        (a)    Authorized Shares.    The authorized Shares which the LLC has authority to issue consist of such number of Class A Shares, Class B Shares, Class C Shares and Class D Shares as shall be determined by the Managing Member. The Managing Member shall have sole discretion to authorize the issuance by the LLC of any Equity Securities (as defined in Section 3.1(c) below). All Shares issued hereunder shall not be Certificated Shares unless otherwise determined by the Managing Member. The ownership by a Member of Class A Shares, Class B Shares, Class C Shares and/or Class D Shares shall entitle such Member to allocations of Profits and Losses and other items and Distributions of cash and other property as set forth in Article IV hereof.

        (b)    Capital Contributions.    Each Shareholder shall make Capital Contributions pursuant to the Merger Agreement or shall make, has made or has been deemed to have made, or contemporaneously with the execution hereof shall make, on the date hereof, Capital Contributions to the LLC, and shall receive Shares, as set forth on the Schedule of Shareholders (as such Schedule may be amended to reflect adjustments to such Capital Contributions and number of Shares corresponding to the per share adjustments to the purchase price pursuant to Section 1.11 of the Merger Agreement and/or to reflect any additional issuances of Shares after the Closing (as defined in the Merger Agreement) pursuant to the Exchange Agreement or otherwise). The Class A Capital Contribution of each of Messrs. Gupta, Talbott and Zarrella shall be equal to the product of (i) the number of shares of GT Equipment Technologies common stock contributed by such Person (reflected on Exhibit A to the Merger Agreement) and (ii) the per share price of the GT Equipment Technologies common stock as finally determined, after giving effect to the working capital adjustment in Section 1.11 of the Merger Agreement. The Capital Contributions for Messrs. Gupta, Talbott and Zarrella as reflected in Schedule of Shareholders as of the Closing have been determined based on an estimate of $106.93670 for such per share price of GT Equipment Technologies common stock and shall be adjusted hereafter to the extent the actual per share price, as finally determined, deviates from such estimate. The Schedule of Shareholders reflects that each Shareholder will receive for its Capital Contribution as of the Closing Class A Shares at a price per share of $6.77630. If the Common Merger Consideration (as defined in the Merger Agreement) plus or minus, as applicable, the per share adjustment pursuant to Section 1.11 of the Merger Agreement (the "Actual Per Share Purchase Price") is greater or less than $106.93670, then (A) the Class A Shares Capital Contribution for each of Messrs. Gupta, Talbott and Zarrella shall equal the product of (x) the Actual Per Share Purchase Price and (y) the number of shares of common stock of GT Equipment Technologies contributed to the LLC by such Person, (B) the number of Class A Shares received by each of Gupta, Talbott and Zarrella in exchange for such Shareholder's Capital Contribution shall be adjusted to equal the quotient of (xx) such Shareholder's Class A Shares Capital Contribution over (yy) $6.77630, and (C) the aggregate number of Class B Shares, Class C Shares and Class D Shares outstanding shall be adjusted so as to cause the ratio of the aggregate number of outstanding Shares of each such class of the LLC to all outstanding Shares to remain unchanged before and after the adjustments set forth in this Section 3.1(b), and for each of clauses (A), (B) and (C) of this Section 3.1(b), the Schedule of Shareholders shall be amended accordingly. In the case of any adjustments pursuant to clause (C) of the immediately preceding sentence, the LLC shall issue such additional Class B Shares to, or cancel such Class B Shares held by, as the case may be, the holders of Class B Shares ratably based on holdings of shares of such class, shall issue such additional Class C Shares to, or cancel such Class C Shares held by, as the case may be, the holders of Class C Shares ratably based on holdings of shares of such class, and shall issue such additional Class D Shares to, or cancel such Class D Shares held by, as the case may be, the holders of Class D Shares ratably based on holdings of shares of such class. Shares of any such class which are so issued to any holder of unvested Shares of such class shall also be unvested, and thereafter shall be subject to vesting in

10

---

accordance with Section 3.2. In addition, each Shareholder acknowledges that additional Class A Shares, Class B Shares, Class C Shares and Class D Shares may be issued pursuant to the Exchange Agreement . Upon any such issuances, the Schedule of Shareholders will be amended accordingly. No subsequent Capital Contributions shall be required from the Shareholders.

        (c)    Issuance of Additional Shares and Interests.    Subject to compliance with Section 3.1(d), and except as otherwise expressly provided in this Agreement, the Managing Member has the power and authority to cause the LLC to issue (i) additional Shares or other interests in the LLC (including to create and issue other classes or series having different rights), (ii) obligations, evidences of indebtedness or other securities or interests convertible or exchangeable into Shares or other interests in the LLC and (iii) warrants, options or other rights to purchase or otherwise acquire Shares or other interests in the LLC (collectively, "Equity Securities"); provided that at any time following the date hereof, the LLC shall not issue Shares to any Person unless such Person shall have executed a counterpart to this Agreement. In such event, (A) the rights of Shareholders in respect of Shares or interests of any class or series shall be diluted on a pro rata basis based on holdings of such Shares or other interests of such class or series, and (B) the Managing Member shall have the power and authority to amend the Schedule of Shareholders solely to reflect such additional issuances and dilution and to make any such other amendments as it deems necessary or desirable to reflect such additional issuances consistent with the foregoing (including, without limitation, power and authority to amend this Agreement to increase the authorized number of Shares of any class or create a new class of Shares and to add the terms of such new class including economic and governance rights which may be different from the Class A Shares, Class B Shares, Class C Shares or Class D Shares or any other outstanding securities).

        (d)    Preemptive Rights.    

11

        3.2 Vesting Shares.    

        (a)   The Class A Shares and Class C Shares shall not be subject to vesting.

        (b)    Class B Shares.    The Class B Shares shall be issued to only employees of GT Equipment Technologies or any of its Subsidiaries (each, a "GT Employee"), in each case subject to vesting in accordance with this Section 3.2(b), and shall vest only so long as the holder thereof remains employed by GT Equipment Technologies or any of its Subsidiaries. Notwithstanding any other provision of this Agreement, no Class B Shares issued to such holder shall vest after the date such holder is no longer employed by GT Equipment Technologies or any of its Subsidiaries (such date, the "Termination Date"), and in no event shall the aggregate number of Class B Shares held by such holder which are deemed to be vested at any time after the Termination Date exceed the aggregate number of Class B Shares held by such holder which are vested on such Termination Date (as determined in accordance with this Section 3.2(b)).

12

---

        (c)    Class D Shares.    The Class D Shares shall be issued to only to GT Employees, in each case subject to vesting in accordance with this Section 3.2(c), and shall vest only so long as the holder thereof remains employed by GT Equipment Technologies or any of its Subsidiaries. Notwithstanding any other provision of this Agreement, no Class D Shares shall vest after such holder's Termination Date, and in no event shall the aggregate number of Class D Shares which are deemed to be vested exceed the aggregate number of Class D Shares which are vested at any time after the Termination Date on such Termination Date (as determined in accordance with this Section 3.2(c)).

13

---

        (d)   Any Shareholder who receives Class B Shares or Class D Shares for services shall make a timely and effective election under Code Section 83(b) with respect to such Shares. The Company and all Shareholders will (a) treat such Shares as outstanding for tax purposes, (b) treat such Shareholder as a partner of the LLC for tax purposes with respect to such Shares and (c) file all tax returns and reports consistently with the foregoing, and neither the Company nor any of its Shareholders will deduct any amount (as wages, compensation or otherwise) for the fair market value of such Shares for federal income tax purposes. Consistent with the foregoing, the Class B Shares and Class D Shares are intended to be treated as "profits interests" under Revenue Procedure 93-27, I.R.B. 1993-24 (June 9, 1993) and Revenue Procedure 2001-43, I.R.B. 2001-34 (August 2, 2001), and the provisions of this Agreement shall be interpreted and applied consistently therewith.

        3.3 Capital Accounts.    

        (a)   The LLC shall maintain a separate Capital Account for each Shareholder according to the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). In accordance with such Treasury Regulation, the Capital Account of each Member shall equal, as of the date hereof, the amount set forth on the Schedule of Shareholders attached hereto and shall be (a) increased by any additional Capital Contributions made by such Member and such Member's share of items of income and gain allocated to such Member pursuant to Article IV and (b) decreased by such Member's share of items of loss, deduction and expense allocated to such Member pursuant to Article IV and any Distributions to such Holder of cash or the Fair Market Value of any other property distributed to such Member. The LLC may (in the sole discretion of the Managing Member), upon the occurrence of the events specified in Treasury Regulation Section 1.704-1(b)(2)(iv)(f), increase or decrease the Capital Accounts in accordance with the rules of such regulation and Treasury Regulation Section 1.704-1(b)(2)(iv)(g) to reflect a revaluation of LLC property.

        (b)   For purposes of computing the amount of any item of LLC income, gain, loss or deduction to be allocated pursuant to Article IV and to be reflected in the Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for this purpose); provided that:

14

---

        3.4 Negative Capital Accounts.    No Shareholder shall be required to pay to any other Shareholder or the LLC any deficit or negative balance which may exist from time to time in such Shareholder's Capital Account (including upon and after dissolution of the LLC).

        3.5 No Withdrawal.    No Person shall be entitled to withdraw any part of such Person's Capital Contributions or Capital Account or to receive any Distribution from the LLC, except as expressly provided herein.

        3.6 Loans From Shareholders.    Loans by Shareholders to the LLC shall not be considered Capital Contributions. If any Shareholder shall loan funds to the LLC in excess of the amounts required hereunder to be contributed by such Shareholder to the capital of the LLC, the making of such loans shall not result in any increase in the amount of the Capital Account of such Shareholder. The amount of any such loans shall be a debt of the LLC to such Shareholder and shall be payable or collectible in accordance with the terms and conditions upon which such loans are made; provided, that such terms and conditions are no more favorable to such lending Shareholder than those which would be agreed to in an orderly transaction with a willing, unaffiliated lender in an arm's-length transaction.

        3.7 Distributions In-Kind.    To the extent that the LLC distributes property in-kind to the Members, the LLC shall be treated as making a distribution equal to the Fair Market Value of such property for purposes of Section 4.1 and such property shall be treated as if it were sold for an amount equal to its Fair Market Value (or such other amount as is required to be used by the Code or applicable Treasury Regulation) and any resulting gain or loss shall be allocated to the Members' Capital Accounts in accordance with Sections 4.2 through 4.4.

        3.8 Transfer of Shares.    In the event of a Transfer of a Share pursuant to Article IX, the Transferee shall succeed to the Transferor's Capital Account pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(l).

        3.9 Repurchase of Shares.    The LLC may elect to purchase all or any portion of the vested Class B Shares pursuant to Section 3.2(b)(iv) by delivering written notice (the "Repurchase Notice") to the holder thereof within 60 days after the Termination Date. The Repurchase Notice shall set forth the number of vested Class B Shares to be acquired from such holder, the aggregate consideration to be paid for such Shares as determined pursuant to Section 3.2(b)(iv), and the time and place for the closing of the transaction. The closing of the repurchase shall take place on the date designated by the LLC in the Repurchase Notice, which date shall not be more than 60 days nor less than 10 days after the date of such Repurchase Notice. The LLC shall pay for the vested Class B Shares to be repurchased by delivery of a check or wire transfer of funds. The LLC shall be entitled to receive customary representations and warranties from the holder regarding such sale of Shares (including representations and warranties regarding good title to such Shares, free and clear of any liens or

15

---

encumbrances) and to require the holder's signature be guaranteed by a national bank or reputable securities broker.

        3.10 Conversion to Corporation.    

        (a)   The Managing Member may, in its sole discretion, either (i) cause the LLC to contribute all or substantially all of its assets to a corporation in a transaction qualified under Section 351(a) of the Code, and thereupon liquidate and dissolve the LLC, (ii) elect to have all Shareholders contribute their Shares to a corporation, in a transaction qualifying under Section 351(a) of the Code, as long as the value of the shares of the corporation received by all Shareholders has a value equal to the value of the Shares transferred, or (iii) otherwise cause the LLC to convert into a corporation, by way of merger, consolidation or otherwise, so long as such conversion does not result in any material liability (including any material liability for Taxes) of any of the Shareholders without their consent and provided that the value of the shares of the corporation received by each Shareholder has a value equal to the value of the Shares transferred. Subject to the foregoing and to Section 3.10(b), the conversion of the LLC or its business into a corporation shall be accomplished pursuant to such terms and in such manner as the Managing Member shall deem appropriate, in its sole discretion; provided, however, that the Managing Member shall use all reasonable efforts to structure the conversion so as to minimize the adverse impact, if any, to the Shareholders.

        (b)   The Managing Member and the other Shareholders shall use all reasonable efforts (including executing a stockholders' agreement) to ensure that the shares of the corporation issued to each Shareholder in connection with any of the transactions referred to in Section 3.10(a) shall have substantively the same rights and be subject to the same restrictions as the Shares of each class held by such Shareholder, including with respect to distributions and transfer restrictions.

ARTICLE IV

DISTRIBUTIONS AND ALLOCATIONS

        4.1 Distributions.    

        (a)    Tax Distributions.    To the extent funds of the LLC are available for distribution by the LLC (as determined by the Managing Member in its sole discretion), the Managing Member shall cause the LLC to distribute to the Shareholders with respect to each Fiscal Quarter of the LLC an amount of cash (a "Tax Distribution") which in the good faith judgment of the Managing Member equals (i) the amount of net taxable income (adjusted to take account of any net taxable losses of the LLC allocable to the Shareholders in prior periods) of the LLC allocable to the Shareholders in respect of such Fiscal Quarter, multiplied by (ii) the sum of the highest marginal federal, state and local income tax rates applicable to an individual living in New York, NY for the relevant type of taxable income, with such Tax Distribution to be made to the Shareholders in the same proportions that taxable income was allocated to the Shareholders during such Fiscal Quarter. Tax Distributions shall be considered advance Distributions to Shareholders under Section 4.1(b).

        (b)    Other Distributions.    Except as otherwise set forth in Section 4.1(a), the Managing Member may in its sole discretion (but shall not be obligated to) make Distributions at any time or from time to time, but shall make distributions in respect of Class A Shares, Class B Shares, Class C Shares and/or Class D Shares only in the following order of priority:

16

---

        (c)    Distributions With Respect to Class B Shares and Class D Shares.    

17

---

        4.2 Allocations.    Except as otherwise provided in Section 4.3 and Section 4.5, Profits and Losses for any Fiscal Year shall be allocated among the Shareholders in such a manner that, as of the end of such Fiscal Year, the sum of (i) the Capital Account of each Shareholder, (ii) such Shareholder's share of Minimum Gain (as determined according to Treasury Regulation Section 1.704-2(g)) and (iii) such Shareholder's partner nonrecourse debt minimum gain (as defined in Treasury Regulation Section 1.704-2(i)(3)) shall be equal to the respective net amounts, positive or negative, which would be distributed to them or for which they would be liable to the LLC under the Delaware Act or otherwise, determined as if all unvested Shares were to vest and the LLC were to (i) liquidate the assets of the LLC for an amount equal to their Book Value and (ii) distribute the proceeds of liquidation pursuant to Section 12.2.

        4.3 Special Allocations.    

        (a)   Losses attributable to partner nonrecourse debt (as defined in Treasury Regulation Section 1.704-2(b)(4)) shall be allocated in the manner required by Treasury Regulation Section 1.704-2(i). If there is a net decrease during a Taxable Year in partner nonrecourse debt minimum gain (as defined in Treasury Regulation Section 1.704-2(i)(3)), Profits for such Taxable Year (and, if necessary, for subsequent Taxable Years) shall be allocated to the Shareholders in the amounts and of such character as determined according to Treasury Regulation Section 1.704-2(i)(4). This Section 4.3(a) is intended to be a "partner nonrecourse debt minimum gain chargeback" provision that complies with the requirements of Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted in a manner consistent therewith.

        (b)   Nonrecourse deductions (as determined according to Treasury Regulation Section 1.704-2(b)(1)) for any Taxable Year shall be allocated to each Shareholder ratably among such Shareholders based upon the number of outstanding Class A Shares held by each such Shareholder immediately prior to such allocation. Except as otherwise provided in Section 4.3(a), if there is a net decrease in the Minimum Gain during any Taxable Year, each Shareholder shall be allocated Profits for

18

---

such Taxable Year (and, if necessary, for subsequent Taxable Years) in the amounts and of such character as determined according to Treasury Regulation Section 1.704-2(f). This Section 4.3(b) is intended to be a Minimum Gain chargeback provision that complies with the requirements of Treasury Regulation Section 1.704-2(f), and shall be interpreted in a manner consistent therewith.

        (c)   If any Shareholder that unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6) has an Adjusted Capital Account Deficit as of the end of any Taxable Year, computed after the application of Sections 4.3(a) and 4.3(b) but before the application of any other provision of this Article IV, then Profits for such Taxable Year shall be allocated to such Shareholder in proportion to, and to the extent of, such Adjusted Capital Account Deficit. This Section 4.3(c) is intended to be a qualified income offset provision as described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted in a manner consistent therewith.

        (d)   Profits and Losses described in Section 3.3(b)(v) shall be allocated in a manner consistent with the manner that the adjustments to the Capital Accounts are required to be made pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(k) and (m).

        (e)   The allocations set forth in Section 4.3(a)-(d) (the "Regulatory Allocations") are intended to comply with certain requirements of Sections 1.704-1(b) and 1.704-2 of the Treasury Regulations. The Regulatory Allocations may not be consistent with the manner in which the Shareholders intend to allocate Profit and Loss of the LLC or make LLC distributions. Accordingly, notwithstanding the other provisions of this Article IV, but subject to the Regulatory Allocations, income, gain, deduction, and loss shall be reallocated among the Shareholders so as to eliminate the effect of the Regulatory Allocations and thereby cause the respective Capital Accounts of the Shareholders to be in the amounts (or as close thereto as possible) they would have been if Profit and Loss (and such other items of income, gain, deduction and loss) had been allocated without reference to the Regulatory Allocations. In general, the Shareholders anticipate that this will be accomplished by specially allocating other Profit and Loss (and such other items of income, gain, deduction and loss) among the Shareholders so that the net amount of the Regulatory Allocations and such special allocations to each such Shareholder is zero. In addition, if in any Fiscal Year or Fiscal Period there is a decrease in partnership Minimum Gain, or in partner nonrecourse debt Minimum Gain, and application of the Minimum Gain chargeback requirements set forth in Section 4.3(a) or Section 4.3(b) would cause a distortion in the economic arrangement among the Shareholders, the Shareholders may, if they do not expect that the LLC will have sufficient other income to correct such distortion, request the Internal Revenue Service to waive either or both of such Minimum Gain chargeback requirements. If such request is granted, this Agreement shall be applied in such instance as if it did not contain such Minimum Gain chargeback requirement.

        (f)    The Members acknowledge that allocations like those described in Proposed Treasury Regulation Section 1.704-1(b)(4)(xii)(c) ("Forfeiture Allocations") result from the allocations of Profits and Losses provided for in this Agreement. For the avoidance of doubt, the LLC is entitled to make Forfeiture Allocations and, once required by applicable final or temporary guidance, allocations of Profits and Losses will be made in accordance with Proposed Treasury Regulation Section 1.704-1(b)(4)(xii)(c) or any successor provision or guidance.

        4.4 Tax Allocations.    

        (a)   The income, gains, losses, deductions and credits of the LLC will be allocated, for federal, state and local income tax purposes, among the Shareholders in accordance with the allocation of such income, gains, losses, deductions and credits among the Shareholders for computing their Capital Accounts; except that if any such allocation is not permitted by the Code or other applicable law, the LLC's subsequent income, gains, losses, deductions and credits will be allocated among the

19

---

Shareholders so as to reflect as nearly as possible the allocation set forth herein in computing their Capital Accounts.

        (b)   Items of LLC taxable income, gain, loss and deduction with respect to any property contributed to the capital of the LLC shall be allocated among the Shareholders in accordance with Code Section 704(c) so as to take account of any variation between the adjusted basis of such property to the LLC for federal income tax purposes and its Book Value using any permitted method selected by the Tax Matters Partner.

        (c)   If the Book Value of any LLC asset is adjusted pursuant to the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f) subsequent allocations of items of taxable income, gain, loss and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Book Value in the same manner as under Code Section 704(c) using any permitted method selected by Tax Matters Partner.

        (d)   Allocations of tax credits, tax credit recapture, and any items related thereto shall be allocated to the Shareholders according to their interests in such items as determined by the Managing Member taking into account the principles of Treasury Regulation Section 1.704-1(b)(4)(ii).

        (e)   Allocations pursuant to this Section 4.4 are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing, any Shareholder's Capital Account or share of Profits, Losses, Distributions or other LLC items pursuant to any provision of this Agreement.

        4.5 Offsetting Allocations.    If, and to the extent that, any Member is deemed to recognize any item of income, gain, deduction or loss as a result of any transaction between such Member and the LLC pursuant to Sections 83, 482, or 7872 of the Code or any similar provision now or hereafter in effect, the Managing Member shall use its reasonable best efforts to allocate any corresponding Profit or Loss of the LLC to the Member who recognizes such item in order to reflect the Members' economic interest in the LLC.

        4.6 Forfeiture of Unvested Shares.    In the event that a Member's unvested Shares are forfeited to the LLC, the Capital Account balance attributable to such unvested Shares shall be allocated among the holders of the outstanding Shares based upon how a distribution of such remaining Capital Account balance would have been made to such holders under Section 4.1.

        4.7 Indemnification and Reimbursement for Payments on Behalf of a Shareholder.    Except as otherwise provided in Section 5.4 and 6.1., if the LLC is required by law to make any payment to a Governmental Entity that is specifically attributable to a Shareholder or a Shareholder's status as such (including, without limitation, federal withholding taxes, state personal property taxes, and state unincorporated business taxes), then such Shareholder shall indemnify and contribute to the LLC in full for the entire amount paid (including interest, penalties and related expenses). The Managing Member may offset Distributions to which a Person is otherwise entitled under this Agreement against such Person's obligation to indemnify the LLC under this Section 4.7. A Shareholder's obligation to indemnify and make contributions to the LLC under this Section 4.7 shall survive the termination, dissolution, liquidation and winding up of the LLC, and for purposes of this Section 4.7, the LLC shall be treated as continuing in existence. The LLC may pursue and enforce all rights and remedies it may have against each Shareholder under this Section 4.7, including instituting a lawsuit to collect such indemnification and contribution with interest calculated at a rate equal to the Base Rate plus three percentage points per annum (but not in excess of the highest rate per annum permitted by law).

Notwithstanding the foregoing, except for issuances of securities to the Managing Member or its Affiliates (subject to Section 3.1(d)), without the approval of the holders of a majority of the Non-Power Fund Equity, the Managing Member shall not approve any transaction between the LLC or any Subsidiary of the LLC on the one hand, and the Managing Member, Power Fund, or any of their respective Affiliates, on the other. No other Member shall have the power and authority to bind the LLC in any way, to do any act that would be (or that could be construed as) binding on the LLC, or to make any expenditures on behalf of the LLC, unless such specific power and authority has been expressly granted in writing to and not revoked from such other Member by the Managing Member.

        5.3 Purchase of Shares.    The Managing Member may cause the LLC to purchase or otherwise acquire Shares, or may purchase or otherwise acquire Shares on behalf of the LLC; provided that this provision shall not in and of itself obligate any Shareholder to sell any Shares to the LLC. So long as any such Shares are owned by or on behalf of the LLC such Shares will not be considered outstanding for any purpose.

        5.4 Limitation of Liability.    

        (a)   Except as otherwise provided herein or in any agreement entered into by such Person and the LLC, and to the maximum extent permitted by the Delaware Act, no present or former Managing Member or any of such Managing Member's Affiliates, employees, agents or representatives shall be liable to the LLC or to any other Member for any act or omission performed or omitted by such Person in good faith in its capacity as a Managing Member of the LLC or otherwise; provided that, except as otherwise provided herein, such limitation of liability shall not apply to the extent the act or omission was attributable to such Person's gross negligence, willful misconduct or knowing violation of law or this Agreement or any other agreement with the LLC. The Managing Member may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its Affiliates, agents or representatives, and the Managing Member shall not be responsible for any misconduct or negligence on the part of any such Person appointed by the Managing Member (so long as such Person was selected in good faith and with reasonable care). The Managing Member shall be entitled to rely upon the advice of legal counsel, independent public accountants and other experts, including financial advisors, and any act of or failure to act by the Managing Member in good faith reliance on such advice shall in no event subject the Managing Member or any of its Affiliates, employees, agents or representatives to liability to the LLC or any Member.

        (b)   Whenever in this Agreement or any other agreement contemplated herein, the Managing Member is permitted or required to take any action or to make a decision in its "sole discretion" or "discretion," with "complete discretion" or under a grant of similar authority or latitude, the Managing Member shall be entitled to consider such interests and factors as it desires (including its interests as a Shareholder), provided that, the Managing Member shall act in good faith.

        (c)   Whenever in this Agreement a Managing Member is permitted or required to take any action or to make a decision in its "good faith" or under another express standard, the Managing Member shall act under such express standard and, to the extent permitted by applicable law, shall not be subject to any other or different standards imposed by this Agreement or any other agreement contemplated herein, and, notwithstanding anything contained herein to the contrary, so long as the Managing Member acts in good faith, the resolution, action or terms so made, taken or provided by the Managing Member shall not constitute a breach of this Agreement or any other agreement contemplated herein or impose liability upon the Managing Member or any of its Affiliates, employees, agents or representatives.

        (d)   To the maximum extent permitted by applicable law, each Member hereby waives any claim or cause of action against the Managing Member or any of its Affiliates, employees, agents and representatives for any breach of any fiduciary duty to the LLC, its Members or any Subsidiary of the LLC by such Person, including as may result from a conflict of interest between the LLC or such Subsidiary and such Person; provided that, except as otherwise provided herein, such waiver shall not apply to the extent the act or omission was attributable to such Person's gross negligence, willful misconduct or knowing violation of law or this Agreement or any other Agreement with the LLC, nor

With respect to any such waived conflict of interest, the Managing Member shall not be obligated to recommend or take any action as a managing member that prefers the interests of the LLC or any Subsidiary or the other Members or Shareholders over the interests of the Managing Member or its Affiliates, employees, agents or representatives and the LLC.

        (e)   Except as otherwise required by law or the provisions of this Agreement, the LLC shall indemnify its present and former Managing Members against any losses, liabilities, damages or expenses (including amounts paid for attorneys' fees, judgments and settlements in connection with any threatened, pending or completed action, suit or proceeding) to which any of such Persons may directly or indirectly become subject for action taken or omitted to be taken on behalf of the LLC or in connection with any involvement with the LLC or any Subsidiary (including serving as a manager, officer, director, consultant or employee of such Subsidiary), but not to the extent attributable to such Indemnified Person's or its Affiliates' gross negligence, willful misconduct or knowing violation of law or for any present or future breaches of any representations, warranties or covenants by such Indemnified Person or its Affiliates, employees, agents or representatives contained herein or in any other agreement with the LLC or to such Person's failure to act in good faith.

ARTICLE VI

RIGHTS AND OBLIGATIONS OF SHAREHOLDERS

        6.1 Limitation of Liability.    Except as otherwise provided by the Delaware Act, the debts, obligations and liabilities of the LLC, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the LLC, and no Shareholder or Member (including the Managing Member) shall be obligated personally for any such debt, obligation or liability of the LLC solely by reason of being a Shareholder or acting as a Member or Managing Member of the LLC, other than such Shareholder's obligation to make Capital Contributions to the LLC pursuant to the terms and conditions hereof. Except as otherwise provided in this Agreement, a Shareholder's liability (in its capacity as such) for LLC liabilities and losses shall be such Shareholder's share of the LLC's assets; provided that a Shareholder shall be required to return to the LLC any Distribution made to it in clear and manifest accounting or similar error. The immediately preceding sentence shall constitute a compromise to which all Shareholders have consented within the meaning of the Delaware Act. Notwithstanding anything contained herein to the contrary, the failure of the LLC to observe any formalities or requirements relating to the exercise of its powers or management of its business and affairs under this Agreement or the Delaware Act shall not be grounds for imposing personal liability on any of the Shareholders or Members (including the Managing Member) for liabilities of the LLC.

        6.2 Lack of Authority.    No Shareholder or Member (other than the Managing Member) in its capacity as such has the authority or power to act for or on behalf of the LLC in any manner, to do any act that would be (or could be construed as) binding on the LLC or to make any expenditures on behalf of the LLC, and the Shareholders and Members hereby consent to the exercise by the Managing Member of the powers conferred on it by law and this Agreement.

        6.3 No Right of Partition.    No Shareholder or Member shall have the right to seek or obtain partition by court decree or operation of law of any LLC property, or the right to own or use particular or individual assets of the LLC.

        (a)   Subject to Section 4.7, the LLC hereby agrees to indemnify and hold harmless any Person (each an "Indemnified Person") to the fullest extent permitted under the Delaware Act, as the same now exists or may hereafter be amended, substituted or replaced (but, in the case of any such amendment, substitution or replacement only to the extent that such amendment, substitution or replacement permits the LLC to provide broader indemnification rights than the LLC is providing immediately prior to such amendment), against all expenses, liabilities and losses (including attorney fees, judgments, fines, excise taxes or penalties) reasonably incurred or suffered by such Person (or one or more of such Person's Affiliates) by reason of the fact that such Person is or was a Shareholder or Member or a partner, member, employee, officer, director, agent or other representative of the Managing member or is or was serving as a Managing Member, officer, director, principal, member, employee, agent or representative of the LLC or is or was serving at the request of the LLC as a Managing Member, officer, director, principal, member, employee, agent or representative of another corporation, partnership, joint venture, limited liability company, trust or other enterprise; provided that (unless the Managing Member otherwise consents) no Indemnified Person shall be indemnified for any expenses, liabilities and losses suffered to the extent attributable to such Indemnified Person's or its Affiliates' gross negligence, willful misconduct or knowing violation of law or for any present or future breaches of any representations, warranties or covenants by such Indemnified Person or its Affiliates, employees, agents or representatives contained herein or in any other agreement with the LLC. Expenses, including attorneys' fees and expenses, incurred by any such Indemnified Person in defending a proceeding shall be paid by the LLC in advance of the final disposition of such proceeding, including any appeal therefrom, upon receipt of an undertaking by or on behalf of such Indemnified Person to repay such amount if it shall ultimately be determined that such Indemnified Person is not entitled to be indemnified by the LLC.

        (b)   The right to indemnification and the advancement of expenses conferred in this Section 6.4 shall not be exclusive of any other right which any Person may have or hereafter acquire under any statute, agreement, law, vote of Managing Member or otherwise.

        (c)   The LLC may maintain insurance, at its expense, to protect any Indemnified Person against any expense, liability or loss relating to the LLC or its business whether or not the LLC would have the power to indemnify such Indemnified Person against such expense, liability or loss under the provisions of this Section 6.4.

        (d)   Notwithstanding anything contained herein to the contrary (including in this Section 6.4), any indemnity by the LLC relating to the matters covered in this Section 6.4 shall be provided out of and to the extent of LLC assets only and neither the Managing Member nor any other Shareholder (unless such Shareholder otherwise agrees in writing or is found in a final decision by a court of competent jurisdiction to have personal liability on account thereof) shall have personal liability on account thereof or shall be required to make additional Capital Contributions to help satisfy such indemnity of the LLC (except as expressly provided herein).

        (e)   If this Section 6.4 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the LLC shall nevertheless indemnify and hold harmless each Indemnified Person pursuant to this Section 6.4 to the fullest extent permitted by any applicable portion of this Section 6.4 that shall not have been invalidated and to the fullest extent permitted by applicable law.

The actions taken by the Members entitled to vote or consent at any meeting (as opposed to by written consent), however called and noticed, shall be as valid as though taken at a meeting duly held after regular call and notice if (but not until), either before, at or after the meeting, the Members entitled to vote or consent as to whom it was improperly held signs a written waiver of notice or a consent to the holding of such meeting or an approval of the minutes thereof. The actions by the Members entitled to vote or consent may be taken by vote of the Members entitled to vote or consent at a meeting or by written consent (without a meeting and without a vote) so long as such consent is signed by the Members having not less than the minimum number of Shares that would be necessary to authorize or take such action at a meeting at which all Members entitled to vote thereon were present and voted. Prompt notice of the action so taken without a meeting shall be given to those Members entitled to vote or consent who have not consented in writing. Any action taken pursuant to such written consent of the Members shall have the same force and effect as if taken by the Members at a meeting thereof.

The Other Members may elect to participate in the contemplated Transfer with respect to the same class of Shares proposed to be Transferred by such holder of Power Fund Equity by delivering written notice to Power Fund within 15 days after delivery of the Sale Notice, and failure to deliver any such notice shall be deemed a waiver of rights under this Section 9.4 with respect to such Transfer. The aggregate consideration to be received by each Shareholder in such Transfer shall be based upon the Pro Rata Share represented by the Shares requested to be included by each Shareholder relative to the Pro Rata Share of all Shares participating in such Transfer held by the Shareholders participating in such Transfer. If no Other Member has elected to participate in the contemplated Transfer (through notice to such effect or expiration of the 15-day period after delivery of the Sale Notice), then Power Fund may, during the 90-day period immediately following the date of the delivery of the Sale Notice, Transfer the Shares specified in the Sale Notice at a price and on terms no more favorable to the Transferee(s) thereof than specified in the Sale Notice. Any Shares identified in the Sale Notice but not Transferred within such 90-day period shall be subject to the provisions of this Section 9.4 upon subsequent Transfer.

        (b)   Power Fund shall not Transfer any of its Shares to any prospective Transferee if such prospective Transferee(s) declines to allow the participation of the Other Members who have elected to participate in such Transfer in accordance with Section 9.4(a), unless Power Fund or its designee acquires the Shares that otherwise would have been sold in such Transfer for the price and on the terms that such Member would have been entitled to receive had such Other Member(s) sold the Shares such Member was entitled to sell in such Transfer. Each Member Transferring Shares pursuant to this Section 9.4 (including in respect of the Transfer to Power Fund or its designees referenced in the immediately foregoing sentence) shall pay its Pro Rata Share of the expenses incurred by the Members in connection with such Transfer and shall be obligated to join based on its Pro Rata Share in any indemnification or other obligations that Power Fund agrees to provide in connection with such Transfer (other than any such obligations that relate specifically to a particular Member such as indemnification with respect to representations and warranties given by a Member regarding such Member's title to and ownership of Shares); provided that no holder shall be obligated in connection with such Transfer to agree to indemnify or hold harmless the Transferees with respect to an amount in excess of the cash proceeds to which such holder is entitled in such Transfer, or to make indemnity payments in excess of the net cash proceeds paid to such holder in connection with such Transfer; provided further, that any escrow proceeds of any such transaction shall be withheld on a pro rata basis among all Shareholders who participate in the Transfer.

If the Approved Sale is structured as a (x) merger or consolidation, each Member holding Shares shall waive any dissenters rights, appraisal rights or similar rights in connection with such merger or consolidation or (y) sale of Shares, each holder of Shares shall agree to sell all of his, her or its Shares and rights to acquire Shares on the terms and conditions approved by the Managing Member.

29

---

        (b)   The obligations of the Members holding Shares with respect to the Approved Sale are subject to the satisfaction of the following conditions: (i) the consideration payable upon consummation of such Approved Sale to all Shareholders shall be allocated among the Shareholders as if distributed pursuant to Section 4.1(b); and (ii) upon the consummation of the Approved Sale, all of the Shareholders of a particular class of Shares shall receive the same amount of consideration per Share of such class (with any non-cash consideration valued in good faith by the Managing Member), as reduced by the aggregate principal amount plus all accrued and unpaid interest on any indebtedness of any holder to the LLC.

        (c)   Notwithstanding anything to the contrary, in connection with an Approved Sale, (i) no Shareholder will be required to make affirmative representations or warranties except as to such Shareholder's due power and authority, non-contravention and ownership of Shares, free and clear of all liens, and (ii) the Shareholders may be severally obligated to join on a pro rata basis (based on the amount by which each holder's share of the aggregate proceeds paid with respect to its Shares would have been reduced had the aggregate proceeds available for distribution to such Shareholders been reduced by the amount of such indemnity) in any indemnification obligation agreed to by the Managing Member in connection with such Approved Sale, except that each Member may be fully liable for obligations that relate specifically to such Shareholder, such as indemnification with respect to representations and warranties given by such Shareholder regarding such Shareholder's title to and ownership of Shares; provided that no holder shall be obligated in connection with such Approved Sale to agree to indemnify or hold harmless the Transferees with respect to an amount in excess of the cash proceeds to which such holder is entitled in such Approved Sale, or to make indemnity payments in excess of the net cash proceeds paid to such holder in connection with such Approved Sale; provided further, that any escrow of proceeds of any such transaction shall be withheld on a pro rata basis among all Shareholders (based on the amount by which each such holder's share of the aggregate proceeds otherwise payable with respect to its Shares would have been reduced had the aggregate proceeds available for distribution to such Shareholders been reduced by the amount placed in escrow). Each Shareholder shall enter into any indemnification or contribution agreement requested by the Managing Member to ensure compliance with this Section 9.5(c) and the provisions of this Section 9.5(c) shall be deemed complied with if the requirement for several liability is addressed through such agreement, even if the purchase and sale agreement or merger agreement related to the Approved Sale provides for joint and several liability.

        (d)   If GT Equipment Technologies or any of its Subsidiaries, the LLC or holders of a majority of the Power Fund Equity enter into any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), the other Shareholders shall, at the request of the holders of a majority of the Power Fund Equity, appoint a "purchaser representative" (as such term is defined in Rule 501 promulgated under the Securities Act) designated by the LLC and reasonably acceptable to the holders of a majority of the Power Fund Equity. If any Shareholder so appoints a purchaser representative, the LLC shall pay the fees of such purchaser representative. However, if any Shareholder declines to appoint the purchaser representative designated by the LLC, such holder shall appoint another purchaser representative (reasonably acceptable to the holders of a majority of the Power Fund Equity), and such holder shall be responsible for the fees of the purchaser representative so appointed.

        (e)   Except as otherwise provided in Section 9.5(d), each Member Transferring Shares pursuant to this Section 9.5 shall pay its Pro Rata Share of the expenses incurred by the Members in connection with such Transfer (including by reducing the portion of the consideration to which such Shareholder would be entitled in such Approved Sale).

        (f)    In addition, if the Managing Member approves a Public Offering or transaction pursuant to Section 3.10, each Shareholder shall, and shall cause its Representatives to, vote for, consent to (to the

30

---

extent it has any voting or consenting rights) and raise no objections against any such transaction, and the LLC, the Managing Member and each Shareholder shall take all reasonable actions in connection with the consummation of any such transaction as requested by the Managing Member.

        (g)   In no manner shall this Section 9.5 be construed to grant to any Shareholder any dissenters' rights or appraisal rights or give any Shareholder any right to vote in any transaction structured as a merger or consolidation (it being understood that the Members have expressly waived rights under Section 18-210 of the Delaware Act and any other dissenters rights, appraisal rights or similar rights (if any) and have granted to the Managing Member the sole right to approve or consent to a merger or consolidation of the LLC without approval or consent of the Members).

        9.6 Void Transfers.    Any Transfer by any Member of any Shares or other interest in the LLC in contravention of this Agreement in any respect (including, without limitation, the failure of the Transferee to execute a counterpart in accordance with Section 9.1(b)) or which would cause the LLC to not be treated as a partnership for U.S. federal income tax purposes shall be void and ineffectual and shall not bind or be recognized by the LLC or any other party. No purported assignee shall have any right to any profits, losses or distributions of the LLC.

        9.7 Effect of Assignment.    

        (a)   Any Member who shall assign any Shares or other interest in the LLC shall cease to be a Member of the LLC with respect to such Shares or other interest and shall no longer have any rights or privileges of a Member with respect to such Shares or other interest.

        (b)   Any Person who acquires in any manner whatsoever any Shares or other interest in the LLC, irrespective of whether such Person has accepted and adopted in writing the terms and provisions of this Agreement, shall be deemed by the acceptance of the benefits of the acquisition thereof to have agreed to be subject to and bound by all of the terms and conditions of this Agreement that any predecessor in such Shares or other interest in the LLC of such Person was subject to or by which such predecessor was bound.

        9.8 Additional Restrictions on Transfer.    

        (a)   Prior to any Transfer of Restricted Shares, the Member proposing to Transfer such Restricted Shares will deliver written notice to the LLC describing in reasonable detail the Transfer or proposed Transfer. In addition, if the Member holding such Restricted Shares delivers to the LLC an opinion of counsel (who may be counsel for the LLC), satisfactory in form and substance to the Managing Member and counsel for the LLC (which opinion may be waived, in whole or in part, at the discretion of the Managing Member) that no subsequent Transfer of such Restricted Shares will require registration under the Securities Act, the LLC will promptly upon such contemplated Transfer deliver new certificates or instruments, as the case may be, for such Restricted Shares which do not bear the restrictive legend relating to the Securities Act as set forth below. If the LLC is not required to deliver new certificates or instruments, as the case may be, for such Restricted Shares not bearing such legend, the Member holding such Restricted Shares will not Transfer the same until the prospective Transferee has confirmed to the LLC in writing its agreement to be bound by the conditions contained in this Section 9.8.

        (b)   Notwithstanding any other provisions of this Article IX, no Transfer of Shares or any other interest in the LLC may be made unless in the opinion of counsel (who may be counsel for the LLC), satisfactory in form and substance to the Managing Member and counsel for the LLC (which opinion may be waived, in whole or in part, at the discretion of the Managing Member), such Transfer would not violate any federal securities laws or any state or provincial securities or "blue sky" laws (including any investor suitability standards) applicable to the LLC or the interest to be Transferred, or cause the LLC to be required to register as an "Investment Company" under the U.S. Investment Company

31

---

Act of 1940, as amended. Such opinion of counsel shall be delivered in writing to the LLC prior to the date of the Transfer.

        (c)   In order to permit the LLC to qualify for the benefit of a "safe harbor" under Code Section 7704, notwithstanding anything to the contrary in this Agreement, no Transfer of any Share or economic interest shall be permitted or recognized by the LLC or the Managing Member (within the meaning of Treasury Regulation Section 1.7704-1(d)) if and to the extent that such Transfer would cause the LLC to have more than 100 partners (within the meaning of Treasury Regulation Section 1.7704-1(h), including the look-through rule in Treasury Regulation Section 1.7704-1(h)(3)).

        9.9 Prospective Transferees.    Subject to the terms of this Agreement, the LLC agrees to cooperate, as may reasonably be requested, by providing information and access to information to any prospective Permitted Transferee in connection with a proposed Transfer, subject to receipt of a confidentiality agreement in form and substance satisfactory to the Managing Member.

        9.10 Legend.    In the event that certificates representing the Shares are issued ("Certificated Shares"), such certificates will bear the following legend:

        9.11 Transfer Fees and Expenses.    Except as provided in Sections 9.3, 9.4 and 9.5, the Transferor and Transferee of any Shares or other interest in the LLC shall be jointly and severally obligated to reimburse the LLC for all reasonable expenses (including attorneys' fees and expenses) of any Transfer or proposed Transfer, whether or not consummated.

ARTICLE X

ADMISSION OF MEMBERS

        10.1 Substituted Members.    In connection with the Transfer of Shares of a Shareholder permitted under the terms of this Agreement, the Transferee shall become a Substituted Member on the later of (i) the effective date of such Transfer, and (ii) the date on which the Managing Member approves such Transferee as a Substituted Member, and such admission shall be shown on the books and records of the LLC.

        10.2 Additional Members.    A Person may be admitted to the LLC as an Additional Member only as contemplated under Section 3.1 and only upon furnishing to the Managing Member (a) a letter of acceptance, in form satisfactory to the Managing Member, of all the terms and conditions of this Agreement, including the power of attorney granted in Section 13.2, and (b) such other documents or instruments as may be necessary or appropriate to effect such Person's admission as a Member. Such

32

---

admission shall become effective on the date on which the Managing Member determines in its sole discretion that such conditions have been satisfied and when any such admission is shown on the books and records of the LLC.

ARTICLE XI

WITHDRAWAL AND RESIGNATION OF SHAREHOLDERS

        11.1 Withdrawal and Resignation of Member.    No Member shall have the power or right to withdraw or otherwise resign from the LLC prior to the dissolution and winding up of the LLC pursuant to Article XII without the prior written consent of the Managing Member (which consent may be withheld by the Managing Member in its sole discretion), except as otherwise expressly permitted by this Agreement or any of the other agreements contemplated hereby. Upon a Transfer of all of a Member's Shares in a Transfer permitted by this Agreement, subject to the provisions of Section 9.7, such Member shall cease to be a Member. Notwithstanding that payment on account of a withdrawal may be made after the effective time of such withdrawal, any completely withdrawing Member will not be considered a Member for any purpose after the effective time of such complete withdrawal, and, in the case of a partial withdrawal, such Shareholder's Capital Account (and corresponding voting and other rights) shall be reduced for all other purposes hereunder upon the effective time of such partial withdrawal.

ARTICLE XII

DISSOLUTION AND LIQUIDATION

        12.1 Dissolution.    The LLC shall not be dissolved by the admission of Additional Members or Substituted Members. The LLC shall dissolve, and its affairs shall be wound up upon the first to occur of the following:

        (a)   at any time by the Managing Member; or

        (b)   the entry of a decree of judicial dissolution of the LLC under Section 35-5 of the Delaware Act or an administrative dissolution under Section 18-802 of the Delaware Act.

        Except as otherwise set forth in this Article XII, the LLC is intended to have perpetual existence. An Event of Withdrawal shall not cause a dissolution of the LLC and the LLC shall continue in existence subject to the terms and conditions of this Agreement.

        12.2 Liquidation and Termination.    On the dissolution of the LLC, the Managing Member shall act as liquidator or may appoint one or more representatives, Members or other Persons as liquidator(s). The liquidators shall proceed diligently to wind up the affairs of the LLC and make final distributions as provided herein and in the Delaware Act. The costs of liquidation shall be borne as an LLC expense. Until final distribution, the liquidators shall continue to operate the LLC properties with all of the power and authority of the Managing Member. The steps to be accomplished by the liquidators are as follows:

        (a)   the liquidators shall pay, satisfy or discharge from LLC funds all of the debts, liabilities and obligations of the LLC (including, without limitation, all expenses incurred in liquidation) or otherwise make adequate provision for payment and discharge thereof (including, without limitation, the establishment of a cash fund for contingent liabilities in such amount and for such term as the liquidators may reasonably determine);

        (b)   as promptly as practicable after dissolution, the liquidators shall (i) determine the Fair Market Value (the "Liquidation FMV") of the LLC's remaining assets (the "Liquidation Assets") in accordance with the definition thereof in this Agreement, (ii) determine the amounts to be distributed to each Shareholder in accordance with Section 4.1(b), and (iii) deliver to each Shareholder a statement (the

33

---

"Liquidation Statement") setting forth the Liquidation FMV and the amounts and recipients of such Distributions;

        (c)   if the holders of a majority of the Power Fund Equity or a majority-in-interest of Non-Power Fund Equity do not deliver written notice to the liquidators disagreeing with the calculations in the Liquidation Statement (a "Statement of Disagreement") within 15 days after the date of delivery of the Liquidation Statement, absent manifest error, the Liquidation Statement shall be final and binding on all Shareholders. In the event such holders give a Statement of Disagreement within such 15-day period, the holders of a majority of the Power Fund Equity or of a majority-in-interest of Non-Power Fund Equity, as applicable, and the liquidators will attempt in good faith to agree on the Liquidation FMV, and any such agreement shall be final and binding on all Shareholders. If such Persons are unable to reach such agreement within 20 days after the date of the Statement of Disagreement, the holders of a majority of the Power Fund Equity or of a majority-in-interest of Non-Power Fund Equity, as applicable, and the liquidators shall each, within 10 days thereafter, select an investment banker or other appraiser with experience in analyzing and making determinations concerning matters in the Business and in valuing entities like the LLC (including calculating distribution mechanisms like that set forth in Section 4.1(b) above), and the two investment bankers/appraisers so selected shall together select a third such investment banker/appraiser similarly qualified. The three investment bankers/appraisers so selected shall each determine the Liquidation FMV in accordance with the definition thereof in this Agreement, shall determine the amount and allocation of Distributions in accordance with Section 4.1 (b), and shall, within 30 days after their retention, provide the written results of such determination to the holders of Power Fund Equity or Non-Power Fund Equity, as applicable, and the liquidators. For purposes hereof, the Liquidation FMV and the amounts to be distributed with respect to each class of Shares shall each be equal to the average of the two appraisals closest to each other with respect thereto, and such amounts shall be final and binding on all Shareholders. The costs of such appraisal shall be borne by the LLC; and

        (d)   as soon as the Liquidation FMV and the proper amounts of Distributions have been determined in accordance with Section 12.2(c) above, the liquidators shall promptly distribute the LLC's Liquidation Assets to the holders of Shares in accordance with Section 4.1(b) above. Any non-cash Liquidation Assets will first be written up or down to their Fair Market Value, thus creating Profit or Loss (if any), which shall be allocated in accordance with Sections 4.2 and 4.3. In making such distributions, the liquidators shall allocate each type of Liquidation Assets (i.e., cash or cash equivalents, etc.) among the Shareholders ratably based upon the aggregate amounts to be distributed with respect to the Shares held by each such holder. To the extent that equity securities of any Subsidiary of the LLC are distributed to any Shareholders in connection with the liquidation, such Shareholders hereby agree to enter into a securityholders agreement with such Subsidiary and each other Shareholder which contains restrictions on the Transfer of such equity security and other provisions (including with respect to the governance and control of such Subsidiary) in form and substance similar to the provisions and restrictions set forth herein (including, without limitation, in Article IX and Article V). The distribution of cash and/or property to a Shareholder in accordance with the provisions of this Section 12.2 constitutes a complete return to the Shareholder of its Capital Contributions and a complete distribution to the Shareholder of its interest in the LLC and all the LLC's property and constitutes a compromise to which all Shareholders have consented within the meaning of the Delaware Act. To the extent that a Shareholder returns funds to the LLC, it has no claim against any other Shareholder for those funds.

        12.3 Cancellation of Certificate.    On completion of the distribution of LLC assets as provided herein, the LLC is terminated (and the LLC shall not be terminated prior to such time), and the Managing Member (or such other Person or Persons as the Delaware Act may require or permit) shall file a certificate of cancellation with the Secretary of State of Delaware, cancel any other filings made pursuant to this Agreement that are or should be canceled and take such other actions as may be

34

---

necessary to terminate the LLC. The LLC shall be deemed to continue in existence for all purposes of this Agreement until it is terminated pursuant to this Section 12.3.

        12.4 Reasonable Time for Winding Up.    A reasonable time shall be allowed for the orderly winding up of the business and affairs of the LLC and the liquidation of its assets pursuant to Section 12.2 in order to minimize any losses otherwise attendant upon such winding up.

        12.5 Return of Capital.    The liquidators shall not be personally liable for the return of Capital Contributions or any portion thereof to the Shareholders (it being understood that any such return shall be made solely from LLC assets).

        12.6 Hart-Scott-Rodino.    In the event the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") is applicable to any Shareholder, the dissolution of the LLC shall not be consummated until such time as the applicable waiting period (and extensions thereof) under the HSR Act have expired or otherwise been terminated with respect to each such Shareholder.

ARTICLE XIII

GENERAL PROVISIONS

        13.1 Information Rights.    The LLC shall provide RBC, Dr. Kedar P. Gupta and Jonathan A. Talbott, in each case so long as such Shareholder continues to own at least one-half of the Shares acquired pursuant to the Merger Agreement as set forth on the Schedule of Shareholders, with the following: (A) as soon as available and in any event within 45 days after the end of each of the first three quarters of each Fiscal Year, consolidated balance sheets of the LLC and its Subsidiaries as of the end of such period, and consolidated statements of income and cash flows of the LLC and its Subsidiaries for the period then ended prepared in conformity with generally accepted accounting principles in the United Stated applied on a consistent basis, except as otherwise noted therein, and subject to the absence of footnotes and year-end adjustments; and (B) as soon as available and in any event within 120 days after the end of each Fiscal Year, a consolidated balance sheet of the LLC and its subsidiaries as of the end of such year, and consolidated statements of income and cash flows of the LLC and its subsidiaries for the year then ended prepared in conformity with generally accepted accounting principles in the United States applied on a consistent basis, except as otherwise noted therein, together with an auditor's report thereon.

        13.2 Power of Attorney.    

        (a)   Each Shareholder hereby constitutes and appoints the Managing Member and the liquidators, with full power of substitution, as his true and lawful agent and attorney-in-fact, with full power and authority in his or its name, place and stead, to execute, swear to, acknowledge, deliver, file and record in the appropriate public offices (A) this Agreement, all certificates and other instruments and all amendments thereof in accordance with the terms hereof which the Managing Member deems appropriate or necessary to form, qualify, or continue the qualification of, the LLC as a limited liability company in the State of Delaware and in all other jurisdictions in which the LLC may conduct business or own property; (B) all instruments which the Managing Member deems appropriate or necessary to reflect any amendment, change, modification or restatement of this Agreement in accordance with its terms; (C) all conveyances and other instruments or documents which the Managing Member and/or the liquidators deems appropriate or necessary to reflect the dissolution and liquidation of the LLC pursuant to the terms of this Agreement, including a certificate of cancellation; and (D) all instruments relating to the admission, withdrawal or substitution of any Shareholder pursuant to Article X or XI.

        (b)   The foregoing power of attorney is irrevocable and coupled with an interest, and shall survive the death, disability, incapacity, dissolution, bankruptcy, insolvency or termination of any Shareholder and the Transfer of all or any portion of his or its Shares and shall extend to such Shareholder's heirs, successors, assigns and personal representatives.

35

---

        13.3 Amendments.    Subject to the right of the Managing Member to amend this Agreement as expressly provided herein, this Agreement may be amended, modified, or waived with the written consent of a majority of the Power Fund Equity; provided that if any such amendment, modification, or waiver would adversely affect in any material respect the rights, preferences or privileges of any Shares as compared with the effect of such amendment, modification or waiver on the rights, preferences or privileges of the Power Fund Equity, such amendment, modification, or waiver shall also require the written consent of the holders of a majority of the Shares so adversely affected. In connection with any amendment, modification or waiver, or other approval hereunder, the Managing Member will have no obligation to provide any information to any Person unless the consent of such Person is required to be obtained in order to effectuate such amendment, modification or waiver; provided that any Person shall, at the request of the LLC or the Company, as the case may be, promptly (and in any event, within three (3) business days) execute and deliver to the LLC or the Company, any amendment, modification or waiver that has been approved in accordance with this Agreement; and provided further that the Managing Member shall be required to inform the holders of Class A Shares of the substance and occurrence of such amendment. The Managing Member may, without the consent of any other Member or Shareholder, amend the Schedule of Shareholders to reflect the admission of any other Member or Shareholder, the creation of issuance of any other Shares or interests in the LLC or the making of any Capital Contributions.

        13.4 Title to LLC Assets.    LLC assets shall be deemed to be owned by the LLC as an entity, and no Shareholder, individually or collectively, shall have any ownership interest in such LLC assets or any portion thereof. Legal title to any or all LLC assets may be held in the name of the LLC, the Managing Member or one or more nominees, as the Managing Member may determine. The Managing Member hereby declares and warrants that any LLC assets for which legal title is held in its name or the name of any nominee shall be held in trust by the Managing Member or such nominee for the use and benefit of the LLC in accordance with the provisions of this Agreement. All LLC assets shall be recorded as the property of the LLC on its books and records, irrespective of the name in which legal title to such LLC assets is held.

        13.5 Remedies.    Each Shareholder shall have all rights and remedies set forth in this Agreement and all rights and remedies which such Person has been granted at any time under any other agreement or contract and all of the rights which such Person has under any law. Any Person having any rights under any provision of this Agreement or any other agreements contemplated hereby shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

        13.6 Successors and Assigns.    All covenants and agreements contained in this Agreement shall bind and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors, legal representatives and permitted assigns, whether so expressed or not.

        13.7 Severability.    Whenever possible, each provision of this Agreement will 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 will not affect any other provision or the effectiveness or validity of any provision in any other jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

        13.8 Counterparts.    This Agreement may be executed simultaneously in two or more separate counterparts, anyone of which need not contain the signatures of more than one party, but each of which will be an original and all of which together shall constitute one and the same agreement binding on all the parties hereto.

36

Wherever a conflict exists between this Agreement and any other agreement, this Agreement shall control but solely to the extent of such conflict.

        13.10 Applicable Law.    This Agreement shall be governed by, and construed in accordance with, the laws 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. Subject to Section 13.19, any dispute relating hereto shall be heard in the state or federal courts of Delaware, and the parties agree to jurisdiction and venue therein.

        13.11 Addresses and Notices.    All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or made when (a) delivered personally to the recipient, (b) telecopied to the recipient (with hard copy sent to the recipient by reputable overnight courier service (charges prepaid) that same day) if telecopied before 5:00 p.m. Los Angeles, California time on a business day, and otherwise on the next business day, or (c) one business day after being sent to the recipient by reputable overnight courier service (charges prepaid).

Any notice to the Managing Member or the LLC shall be deemed given if received by the Managing Member at the principal office of the LLC designated pursuant to Section 2.5.

        13.12 Creditors.    None of the provisions of this Agreement shall be for the benefit of or enforceable by any creditors of the LLC or any of its Affiliates, and no creditor who makes a loan to the LLC or any of its Affiliates may have or acquire (except pursuant to the terms of a separate agreement executed by the LLC in favor of such creditor) at any time as a result of making the loan any direct or indirect interest in LLC Profits, Losses, Distributions, capital or property other than as a secured creditor.

        13.13 Waiver.    No failure by any party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute a waiver of any such breach or any other covenant, duty, agreement or condition.

        13.14 Further Action.    The parties agree to execute and deliver all documents, provide all information and take or refrain from taking such actions as may be necessary or appropriate to achieve the purposes of this Agreement.

37

---

        13.15 Offset.    Whenever the LLC is to pay any sum to any Shareholder or any Affiliate or related person thereof, any amounts that such Shareholder or such Affiliate or related person owes to the LLC under any promissory note issued to the LLC as partial payment for any Shares of the LLC may be deducted from that sum before payment.

        13.16 Entire Agreement.    This Agreement and the Registration Rights Agreement, those documents expressly referred to herein and other documents dated as 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.

        13.17 Opt-in to Article 8 of the Uniform Commercial Code.    The Shareholders hereby agree that the Shares shall be securities governed by Article 8 of the Uniform Commercial Code of the State of Delaware (and the Uniform Commercial Code of any other applicable jurisdiction).

        13.18 Delivery by Facsimile.    This Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall reexecute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation or enforceability of a contract and each such party forever waives any such defense.

        13.19 Arbitration.    Except as set forth in Section 13.5, any controversy or claim arising out of or relating to this Agreement shall be settled exclusively by final and binding arbitration in accordance with the rules of the American Arbitration Association and shall take place in Los Angeles, California. Judgment upon the arbitration award may be entered in any court having jurisdiction thereof. In the event that a judgment is made pursuant to this Section 13.19, all reasonable out of pocket costs and reasonable legal costs incurred by the prevailing party shall be paid by the non-prevailing party. In the event that a non-arbitrated settlement is reached, each party shall pay their own respective costs and fees incurred thereby.

        13.20 Survival.    Section 6.7 shall survive and continue in full force in accordance with its terms notwithstanding any termination of this Agreement or the dissolution of the LLC.

        13.21 Expenses.    The LLC shall pay (or cause its Subsidiaries to pay) and hold Power Fund harmless against liability for the payment of the reasonable out-of-pocket expenses of such Persons (including the reasonable fees and expenses of legal counsel or other advisors) in the performance of its duties as Managing Member and in connection with (i) start-up and organizational costs in connection with the formation of the LLC and its Subsidiaries and the commencement of their respective businesses and operations, (ii) the preparation, negotiation and execution of this Agreement, any debt financing documents and each other agreement executed in connection herewith, and the evaluation and consummation of the transactions contemplated hereby and thereby, (iii) any amendments or waivers (whether or not the same become effective) under or in respect of this Agreement or such other agreements, (iv) the enforcement of the rights granted under this Agreement, the Merger Agreement or such other agreements or Power Fund's direct or indirect investment in the LLC or GT Equipment Technologies or their respective Subsidiaries, (v) any filing with any governmental agency with respect to such Person's investment in the LLC or in any other filing with any governmental agency with respect to the LLC that mentions such Person, (vi) any fees and

38

---

expenses of any lenders to the LLC and its Subsidiaries, and (vii) any transaction, claim, event, or other matter relating to GT Equipment Technologies or its Subsidiaries or the transactions contemplated hereby as to which such Person seeks advice of counsel. For the avoidance of doubt, GT Equipment Technologies' (and it Subsidiaries') responsibilities in this respect shall exclude expenses incurred by Power Fund in its role as Buyer under the Merger Agreement, specifically excluding legal, operational, and financial due diligence expenses, related out of pocket expenses, and legal advisory services related to the drafting and negotiation of the Merger Agreement (together with the exhibits thereto) and the related Disclosure Schedules. Nothing in Section 6.4 or elsewhere in this Agreement shall require reimbursement of expenses of any Member or Shareholder (other than Power Fund) in connection with the matters referred to in clauses (i)—(vii) of this Section 13.21.

        13.22 Acknowledgements.    Upon execution and delivery of a counterpart to this Agreement or a joinder to this Agreement, each Member and Additional Member shall be deemed to acknowledge to Power Fund as follows: (a) the determination of such Member or Additional Member to purchase Shares pursuant to this Agreement and any other agreement referenced herein has been made by such Member or Additional Member independent of any other Member and independent of any statements or opinions as to the advisability of such purchase or as to the properties, business, prospects or condition (financial or otherwise) of the LLC or the Company and its Subsidiaries which may have been made or given by the Managing Member or by any agent or employee of the Managing Member, (b) the Managing Member has not acted as an agent of such Member or Additional Member in connection with making its investment hereunder and that the Managing Member shall not be acting as an agent of such Member or Additional Member in connection with monitoring its investment hereunder, (c) Power Fund has retained Kirkland & Ellis LLP in connection with the transactions contemplated hereby and expects to retain Kirkland & Ellis LLP as legal counsel in connection with the management and operation of the investment in the LLC and GT Equipment Technologies, (d) Kirkland & Ellis LLP is not counsel to any other Members and is not representing and will not represent any other Member or Additional Member in connection with the transaction contemplated hereby or any dispute which may arise between Power Fund, on the one hand, and any other Member or Additional Member, on the other hand, (e) such Member or Additional Member will, if it desires legal advice with respect to any of the transactions contemplated hereby, retain its own independent counsel, and (f) Kirkland & Ellis LLP may represent Power Fund in connection with any and all matters contemplated hereby (including, without limitation, any dispute between Power Fund, on the one hand, and any other Member or Additional Member, on the other hand) and such Member or Additional Member waives any conflict of interest in connection with such representation by Kirkland & Ellis LLP.
