4.3 Preferential Purchase Right; Change of Member Control

(a) Preferential Purchase Right. Except for Dispositions permitted in accordance with Section 4.2(e) and Section 4.3(d), if a Member at any time proposes to Dispose of all or any portion of its Membership Units in a transaction that complies with the requirements of Section 4.2, then such Member shall promptly give notice of such proposed transaction (the “Disposition Notice”) to the Company and each other Member. The Disposition Notice shall set forth all material terms of the proposed Disposition, including the name and address of the prospective acquirer, the fact that the prospective acquirer has agreed to purchase all or a specified part of the Membership Units owned by the Disposing Member, the price to be paid for such Membership Units, and the other material terms and conditions of the proposed Disposition.

If the Purchasing Members fail to exercise their Preferential Right to purchase all of


^**		This Portion has been redacted pursuant to a confidential treatment request.

the Membership Units included in such proposed Disposition within such ^**, the Disposing Member shall give the Purchasing Members a second notice of the Membership Units which were not subscribed for. Unless on or before the ^** after such second notice the Purchasing Members have either (i) each elected, by notice to the Disposing Member, to purchase its respective pro-rata share of all of the Membership Units not subscribed for by such other Members or (ii) collectively elected, by notice delivered by all Purchasing Members to the Disposing Member, to purchase all of the Membership Units not subscribed for by such other Members, allocated among the Purchasing Members as set forth in such notice, then the Nondisposing Members shall be deemed to have elected not to acquire the Membership Units of the Disposing Member. For purposes of the second election under this Section, the pro-rata share of the Purchasing Members shall be determined including only the Membership Percentages of the Purchasing Member(s) participating in such second election and shall treat the Class A Membership Units and Class B Membership Units as separate classes and not together as a single class. A Member that fails to exercise a Preferential Right during the applicable periods set forth in this Section 4.3(a) shall be deemed to have waived such Preferential Right with respect to the Disposition described in such Disposition Notice, but not any future Preferential Right with respect to any other Disposition described in any other Disposition Notice.

(b) Closing following Exercise Notice. If the Purchasing Members exercise the Preferential Right to acquire all of the Membership Units described in the Disposition Notice, the closing of the purchase of the Membership Units of the Disposing Member specified in such Disposition Notice shall occur at the principal place of business of the Company on the ^** after the date on which the Disposition Notice is given, unless the Disposing Member and the Purchasing Members agree upon a different place or date. At the closing, (A) the Disposing Member shall execute and deliver to each Purchasing Member (1) an assignment of the Membership Units being transferred to such Purchasing Member, in form and substance reasonably acceptable to such Purchasing Member, containing a general warranty of title as to such Membership Units (including that such Membership Units are free and clear of all Encumbrances) and (2) any other instruments reasonably requested by such Purchasing Member to give effect to the purchase; and (B) such Purchasing Member shall deliver to the Disposing Member in immediately available funds its pro-rata portion, based on the Class A Membership Units and the Class B Membership Units, as applicable, actually being purchased by each Purchasing Member, of the purchase price for the Class A Membership Units and the Class B Membership Units included in such proposed Disposition as set forth in the Disposition Notice.

(c) Failure to Exercise. If no Member timely delivers an Exercise Notice (or if the Purchasing Members do not exercise the Preferential Right to acquire all of the Membership Units described in the Disposition Notice), then the Disposing Member shall have the right, subject to compliance with the provisions of this Article IV, to Dispose of its Membership Units or the portion thereof specified in the Disposition Notice on or before the ^** after the date the Disposition Notice was given to the proposed Assignee strictly in accordance


^**		This Portion has been redacted pursuant to a confidential treatment request.

with the terms of the Disposition Notice. If, however, the Disposing Member fails to so Dispose of the Membership Units on or before such ^**, the proposed Disposition shall again become subject to the Preferential Right.

(d) Exception for NRG Transfer. ^**

(e) Change of Control.

(i) A Change of Control shall be deemed to be a Disposition of all of the Membership Units of the Member with respect to which the Change of Control occurs for purposes of this Section 4.3. The Member with respect to which such Change of Control occurs shall be the Disposing Member, and the Disposing Member shall give notice thereof (the “Change of Control Notice”) to the Company and each other Member on or before the ^**after the earlier to occur of such Change of Control or the relevant Affiliate of the Disposing Member entering into a binding agreement to effect such Change of Control. Each other Member shall have the Preferential Right, exercisable by notice (the “Change of Control Exercise Notice” and each exercising Member a “Change of Control Purchasing Member”) to each other Member on or before the ^** after the Change of Control Notice is given (the period from the date on which the Change of Control Notice is given in respect of such Change of Control to such ^** being herein called the “Change of Control Election Period”), to acquire such Change of Control Purchasing Member’s pro-rata portion of all of the Class A Membership Units and the Class B Membership Units of the Disposing Member (A) ^**, or (B) ^**. Each Change of Control Purchasing Member’s pro-rata portion shall be based on the Class A Membership Percentages and the Class B Membership Percentages, as applicable, of each Change of Control Purchasing Member^**. If the Change of Control Purchasing Members fail to exercise their Preferential Right to purchase all of the Membership Units of the Disposing Member within such ^**, the Disposing Member shall give the Change of Control Purchasing Members a second notice of the Membership Units which were not subscribed for. Unless on or before the 15^th Day after such second notice the Change of Control Purchasing Members have either (i) each elected, by notice to the Disposing Member, to purchase its respective pro-rata share of all of the Membership Units not subscribed for by such other Members or (ii) collectively elected, by notice delivered by all Change of Control Purchasing Members to the Disposing Member, to purchase all of the Membership Units not subscribed for by such other Members, allocated among the Purchasing Members as set forth in such notice, then the Nondisposing Members shall be deemed to have elected not to acquire the Membership Units of the Disposing Member. For purposes of the second election under this Section, the pro-rata share of the Change of Control Purchasing Members shall be determined including only the Membership Percentages of the Change of Control Purchasing Member(s) participating in such second election and shall treat the Class A


^**		This Portion has been redacted pursuant to a confidential treatment request.

Membership Units and Class B Membership Units as separate classes and not together as a single class. In any event, the Change of Control Purchasing Members may agree amongst themselves as to their respective shares of the Membership Units to be acquired by them.

After the Toshiba Committed Contributions have been fully contributed to the Company in cash, Capital Calls shall be made to all Members, and each Member may (but shall not be obligated to), on or before the ^**after such Capital Call, pay to the Company in cash such Member’s Class A Membership Percentage or Class B Membership Percentage, as applicable, of the amount for which the Capital Call is made. If any Member elects not to make a contribution in response to a Capital Call, the other Members shall have the right, pro-rata in accordance with their respective Class A Membership Percentages or Class B Membership Percentages, as applicable, to make such contributions to the capital of the Company (with the result that the Class A Membership Percentage or the Class B Membership Percentage of the non-contributing Members will be diluted on a dollar-for-dollar basis). An additional Membership Unit of the applicable Class shall be issued to each Member for each $^** of each Capital Contribution made in respect of such Class in accordance with this Section 6.2(e).

6.3 Failure to Contribute.

(a) Noncontributing Member. If the Toshiba Member does not contribute on the date required a Toshiba Committed Contribution or if any other Member does not contribute on the date required all or any portion of a Capital Contribution that such Member has committed to make in accordance with this Agreement, the Company may exercise, on notice to such Member (the “Noncontributing Member”), one or more of the following remedies:


^**		This Portion has been redacted pursuant to a confidential treatment request.

(i) taking such action (including court proceedings) as the Company may deem appropriate to obtain payment by the Noncontributing Member of the portion of the Noncontributing Member’s Capital Contribution that is in default, together with interest thereon at the Default Rate from the date that the Capital Contribution was due until the date that it is made, all at the cost and expense of the Noncontributing Member;

(ii) permitting the other Members to advance the portion of the Noncontributing Member’s Capital Contribution that is in default;

(iii) exercising the rights of a secured party under the Uniform Commercial Code of the State of Delaware, as more fully set forth in Section 6.3(b); or

(iv) exercising any other rights and remedies available at Law or in equity.

(b) Pledge. The Toshiba Member grants to the Company, as security for the payment of the Toshiba Committed Contributions, and each other Member that at any time commits to the Company to make a Capital Contribution grants to the Company, as security, for the payment of such Capital Contributions, a security interest in and a general lien on its Class A Membership Units and its Class B Membership Units and the proceeds thereof, all under the Uniform Commercial Code of the State of Delaware. On any default in the payment of a Capital Contribution, the Company is entitled to all the rights and remedies of a secured party under the Uniform Commercial Code of the State of Delaware with respect to the security interest granted in this Section 6.3(b). The Toshiba Member and each other Member at any time granting such security interest shall execute and deliver to the Company all financing statements and other instruments that the Company may reasonably request to effectuate and carry out the preceding provisions of this Section 6.3(b).

6.4 Return of Contributions. Except as expressly provided herein, a Member is not entitled to the return of any part of its Capital Contributions or to be paid interest in respect of either its Capital Accounts or its Capital Contributions. An unrepaid Capital Contribution is not a liability of the Company or of any Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contributions.

6.5 Capital Accounts. Both a Class A Capital Account and a Class B Capital Account shall be established and maintained for each Member. In connection with the contribution by the NRG Member to the Company of the NRG Committed Contributions, the NRG Member’s Class A Capital Account and Class B Capital Account have each been credited with a contribution to the capital of the Company equal to $^**and $^**, respectively. In connection with the contribution by the Toshiba Member to the Company of the Toshiba Initial Contribution, the Toshiba Member’s Class A Capital Account has been credited with a contribution to the capital of the Company equal to the Toshiba Initial Contribution. In connection with the further Toshiba Committed Contributions to be made on May 1 of each year in accordance with Section 6.2(b), such Capital Contributions shall be allocated by the Company


^**		This Portion has been redacted pursuant to a confidential treatment request.

and credited to the Toshiba Member’s Class A Capital Account and/or Class B Capital Account in accordance with the Company’s expected application of such Capital Contributions to budgeted expenditures of the Company. To the extent that Toshiba Committed Contributions in excess of $^**are used to pay costs or expenses of or invested in the Class A Business, the Class A Capital Accounts and Class B Capital Accounts of the Toshiba Member and the NRG Member shall be adjusted to reflect^**. After giving effect to the foregoing credits and adjustments to the Class A Capital Account and the Class B Capital Account of the Toshiba Member and the NRG Member, each Member’s Capital Account for each Class shall be increased by the amount of money contributed by that Member to the Business of that Class, the fair market value of property contributed by that Member to the Business of that Class (net of liabilities secured by such contributed property that the Company is considered to assume or take subject to under Section 752 of the Code) in respect of the Business of that Class, and allocations to that Member of income and gain (or items thereof) of the Business of that Class, including income and gain exempt from tax and income and gain described in Treasury Regulation Section 1.704-1(b)(2)(iv)(g), but excluding income and gain described in Treasury Regulation Section 1.704-1(b)(4)(i), and shall be decreased by the amount of money distributed to that Member by the Company in respect of the Business of that Class, the fair market value of property distributed to that Member by the Company (net of liabilities secured by such distributed property that such Member is considered to assume or take subject to under Section 752 of the Code) in respect of the Business of that Class, allocations to that Member of expenditures of the Company described (or treated as described) in Section 705(a)(2)(B) of the Code in respect of the Business of that Class, and allocations of Company loss and deduction (or items thereof) in respect of the Business of that Class, including loss and deduction described in Treasury Regulation Section 1.704-1(b)(2)(iv)(g), but excluding items loss or deduction described in Treasury Regulation Sections 1.704-1(b)(4)(i) or 1.704-1(b)(4)(iii). The Members’ Class A Capital Accounts and Class B Capital Accounts shall also be maintained and adjusted (and the items allocated pursuant to Section 7.4 will be calculated) as permitted by the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(f) and as required by the other provisions of Treasury Regulation Sections 1.704-1(b)(2)(iv) and 1.704-1(b)(4), including adjustments to reflect the allocations to the Members of depreciation, depletion, amortization, and gain or loss as computed for book purposes rather than the allocation of the corresponding items as computed for tax purposes, as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(g). A Member shall have a single Class A Capital Account or Class B Capital Account, as applicable, that reflects all Membership Units of that Class held by such Member, regardless of the time or manner in which such Membership Units were acquired. Upon the Disposition of all or a portion of the Class A Membership Units or Class B Membership Units owned by a Member, the Capital Account of the Disposing Member that is attributable to such Class A Membership Units or Class B Membership Units, as applicable, shall carry over to the Assignee in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(l).

ARTICLE VII
DISTRIBUTIONS AND ALLOCATIONS

7.1 Tax Distributions. Prior to making distributions pursuant to Section 7.2, on each Tax Distribution Date, the Company shall, subject to the availability of funds, distribute to each Member in cash an amount equal to such Member’s Assumed Tax Liability, if any. “Tax Distribution Date” means any date that is two Business Days prior to the date for the income tax return of a corporate calendar year taxpayer (without regard to extensions). “Assumed Tax Liability” of each Member means an amount equal to (i) the cumulative amount of federal income taxes (including any applicable estimated taxes), determined taking into account the character of income and loss allocated as it affects the applicable tax rate, that the Board estimates would be due from such Member as of such Tax Distribution Date, (x) assuming such Member were a corporation who earned solely the items of income, gain, deduction, loss, and/or credit allocated to such Member pursuant to Section 7.4, (y) after taking proper account of loss carryforwards available to corporate taxpayers resulting from losses allocated to the Members by the Company, to the extent not taken into account in prior periods, and (z) assuming that such Member is subject to tax at the highest applicable rate, reduced by (ii) all previous distributions made to such Member pursuant to this Section 7.1. Distributions pursuant to this Section 7.1 shall be treated as an advance distribution under Section 7.2 and shall offset future distributions that such Member would otherwise be entitled to receive pursuant to Section 7.2.

7.2 Regular Distributions. The Board may from time to time distribute to the Members of each Class, pro-rata in accordance with their Membership Percentages with respect to such Class, such amounts as the Board may determine from the funds on hand of the Business of that Class, after the payment of all then-due obligations of the Company relating to the Business of that Class and the establishment of reasonable reserves for such Business’s liabilities, obligations, working capital and other anticipated needs, to the extent the Board determines that the Company is not restricted by contract or Law from making a distribution to the Members from such funds.

7.3 Member Withdrawals. Notwithstanding anything in this Article VII to the contrary, if a Member withdraws or resigns from the Company, such Member shall not have any right to any distributions or allocations upon the dissolution and winding up of the Company.

7.4 Allocations.

(a) In General. For accounting and income tax purposes, except as provided in Sections 7.4(a)(ii) and 7.5 and subject to Section 11.2,

(i) Each item of income, gain, loss, deduction and credit of the Business of each Class shall be allocated among the Members in accordance with their Membership Percentages with respect to such Class; and

(ii) With respect to any period during which an event occurs that results in an adjustment of the Class A Membership Percentages and all subsequent periods, prior to making any allocations pursuant to Section 7.4(a)(i) relating to the Class A Business, items of income, gain, loss and deduction relating to the Class A Business will be allocated in a

manner that results in the Adjusted Capital Accounts of the Members in respect of the Class A Business to be in proportion to their Class A Membership Percentages. With respect to any period during which an event occurs that results in an adjustment of the Class B Membership Percentages and all subsequent periods, prior to making any allocations pursuant to Section 7.4(a)(i) relating to the Class B Business, items of income, gain, loss and deduction relating to the Class B Business will be allocated in a manner that results in the Adjusted Capital Accounts of the Members in respect of the Class B Business to be in proportion to their Class A Membership Percentages.

(b) Special Allocations. Notwithstanding any other provisions of Section 7.4(a), the following special allocations shall be made for each taxable period:

(i) Notwithstanding any other provision of this Section 7.4, if there is a net decrease in Company Minimum Gain for a Business during any Company taxable period, each Member shall be allocated items of income and gain from that Business for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Section 1.704-2(f)(6),(g)(2), and (j)(2)(i). For purposes of this Section 7.4(b)(i), the Capital Account of each Member for each Class shall be determined and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 7.4 with respect to such taxable period. This Section 7.4(b)(i) is intended to comply with the minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Notwithstanding the other provisions of this Section 7.4(b)(ii) (other than 1.1(b)(i) above), if there is a net decrease in Member Nonrecourse Debt Minimum Gain with respect to a Class during any Company taxable period, any Member with a share of Member Nonrecourse Debt Minimum Gain with respect to such Class at the beginning of such taxable period shall be allocated items of income and gain from the Business of that Class for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Section 1.704-2(i)(4) and (j)(2)(ii). For purposes of this Section 7.4(b)(ii) the balance of each Member’s Adjusted Capital Account with respect to that Class shall be determined, and the allocation of income and gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 7.4(b)(ii), other than Section 7.4(b)(i) with respect to such taxable period. This Section 7.4(b)(ii) is intended to comply with the Member Nonrecourse Debt Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Except as provided in Section 7.4(b)(i) and Section 7.4(b)(ii), in the event that any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6) in respect of its Membership Units of a Class, items of income and gain from the Business of that Class shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by such Treasury Regulation, the deficit balance, if any, in its Adjusted Capital Account of that Class created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Section 7.4(b)(i) and Section 7.4(b)(ii).

(iv) If any Member has a deficit balance in its Adjusted Capital Account for a Class at the end of any Company taxable period, such Member shall be specially allocated items of gross income and gain from the Business of that Class in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 7.4(b)(iv) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account for that Class after all other allocations provided in this Section 7.4(b)(iv) have been tentatively made as if this Section 7.4(b)(iv) were not in this Agreement.

(v) Nonrecourse Deductions attributable to the Business of a Class for any taxable period shall be allocated to the Members in accordance with their Membership Percentages in respect of that Class.

(vi) Member Nonrecourse Deductions relating to the Business of a Class for any taxable period shall be allocated 100% to the Member that bears the Economic Risk of Loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Members in accordance with the ratios in which they share such Economic Risk of Loss. This Section 7.4(b)(vi) is intended to comply with the provisions of Treasury Regulation 1.704-2(i) and shall be interpreted consistently therewith.

(vii) To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Sections 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such provisions.

(viii) Notwithstanding any other provision of this Section 7.4(b)(viii), other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss and deduction allocated to each Member pursuant to the Required Allocations and Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Member under the Agreed Allocations if the Required Allocations had not otherwise been provided for in this Section 7.4(b)(viii).

7.5 Tax Allocations. For income tax purposes, income, gain, loss, and deduction with respect to property contributed to the Company by a Member or revalued pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(f) shall be allocated among the Members in a manner that takes into account the variation between the adjusted tax basis of such property and its book value, as required by Section 704(c) of the Code and Treasury Regulation Section 1.704-1(b)(4)(i), using an allocation method (other than the Remedial Method with respect to the NRG Contributed Assets) determined by the Tax Matters Member and with prior consent of the Toshiba Member, which consent shall not be unreasonably withheld.

7.6 Allocation Mechanics. A time and expenses system will be implemented to track employee time and out-of-pocket expenses attributable to the Class A Business and the Class B Business. Such time and expenses attributable to the Class A Business shall be charged to the Class A Business. General and administrative costs and expenses not attributable directly to either the Class A Business or the Class B Business shall be allocated 25% to the Class A Business and 75% to the Class B Business from and after the Effective Date, with adjustments to such allocation to reflect changes in the Company’s activities to be made on a basis to be mutually agreed.

7.7 Varying Interests. All items of income, gain, loss, deduction or credit allocable to any Membership Units that may have been transferred shall be allocated between the transferor and the transferee based on the portion of the calendar year during which each was recognized as owning those Membership Units; provided, however, that this allocation must be made in accordance with a method permissible under Section 706 of the Code and the regulations under it.

ARTICLE VIII

Neither the Company nor any Member shall make an election for the Company to be excluded from the application of the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state law and no provision of this Agreement (including Section 2.7) shall be construed to sanction or approve such an election.

8.3 Tax Matters Member.

(a) Appointment; Duties. The NRG Member shall be the “tax matters partner” of the Company pursuant to Section 6231(a)(7) of the Code (the “Tax Matters Member”). The Tax Matters Member shall take such action as may be necessary to cause, to the extent possible, each other Member to become a “notice partner” within the meaning of Section 6223 of the Code.

(c) Administrative Adjustments. No Member shall file a request pursuant to Code Section 6227 for an administrative adjustment of Company items for any taxable year without first notifying the other Member.

If such consent is not obtained within 30 Days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member, including the Tax Matters Member, may file a request for administrative adjustment on its own behalf. Any Member intending to file a petition under Code Sections 6226, 6228 or other Code Section with respect to any item involving the Company shall notify the other Member of such intention and the nature of the contemplated proceeding. In the case where the Tax Matters Member is the Member intending to file such petition on behalf of the Company, such notice shall be given within a reasonable period of time to allow the other Member to participate in the choosing of the forum in which such petition will be filed.

(d) Notice of Inconsistent Treatment.

DISPUTE RESOLUTION

10.1 Disputes. Any and all claims, counterclaims, demands, causes of action, disputes, controversies, and other matters in question arising out of or relating to this Agreement, or to the alleged breach hereof, or in any way relating to the subject matter of this Agreement or the relationship between the Members created by this Agreement (whether extra-contractual in nature, sounding in contract, tort or otherwise, or provided for by federal or state statute, common law or otherwise) (hereafter a “Dispute”) shall be finally resolved by binding arbitration under the Non-Administered Arbitration Rules of the International Institute for Conflict Prevention and Resolution (the “Rules”) then in force to the extent such Rules are not inconsistent with the provisions of this Agreement.

10.2 Negotiation to Resolve Disputes. If a Dispute arises out of or relates to this Agreement, a Member may give notice to all other Members that it intends to initiate the dispute resolution procedures set forth herein. Promptly upon receipt of such notice, each Member that is a party to the Dispute (each, a “Disputing Member”) shall refer such Dispute to a senior executive officer (“SEO”) of each Disputing Member (or of Toshiba’s Power Systems Company, in the case of the Toshiba Member). The SEOs will meet in person or by teleconference as soon as mutually practicable in order to try and resolve the Dispute. If the SEOs are unable to resolve the Dispute on or before the 30^th Day after such notice, any Disputing Member may commence an arbitration under this Article X by notifying each Member (an “Arbitration Notice”).

10.3 Selection of Arbitrators.

(a) Three Arbitrators. Any arbitration conducted under this Article X shall be heard by three arbitrators (each an “Arbitrator” and collectively the “Tribunal”) selected in accordance with this Section 10.3. Each Disputing Member and any proposed Arbitrator shall, as soon as practicable, disclose to the other Disputing Members any business, personal or other relationship or affiliation that may exist between any Member and the proposed Arbitrators. The Disputing Members may then object to any of the proposed Arbitrators on the basis of such relationship or affiliation. The validity of any such objection shall be determined according to the Rules.

(b) Selection of Arbitrators. Except as provided for in this Section 10.3, the Tribunal shall be appointed according to the Rules. In the Arbitration Notice, the Disputing Member requesting arbitration shall nominate one Arbitrator. The Disputing Member named as respondent by the claimant shall nominate one Arbitrator. Within 30 Days of the appointment of the second Arbitrator, the two party-appointed Arbitrators shall appoint a third Arbitrator who shall chair the arbitration. Where the Dispute at issue involves more than two Disputing Members, the International Institute for Conflict Prevention and Resolution (“CPR”) shall provide a list of potential Arbitrators. Within seven (7) days of receiving this list, each Disputing Member shall provide to CPR a ranking of the potential Arbitrators on such list showing such Disputing Member’s order of preference among such proposed Arbitrators, with any one or more Disputing Members who are Affiliates of one another submitting one common ranked list. The CPR shall then appoint all three Arbitrators as it shall determine in its discretion but taking into account to the extent practical the Disputing Members’ preferences.

10.4 Conduct of Arbitration. The Tribunal shall expeditiously (and, if practicable, consistent with the Tribunal’s primary responsibility to justly adjudicate the dispute before it, within 180 Days after the appointment of the third Arbitrator) hear and decide all matters concerning the Dispute. Any arbitration hearing shall be held in Washington, D.C. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et. seq. Except as expressly provided to the contrary in this Agreement, the Tribunal shall have the power to gather such materials, information, testimony and evidence as it deems relevant to the dispute before it (and each Member will provide such materials, information, testimony and evidence requested by the Tribunal, subject to such protective orders as the Tribunal determines necessary for the protection of any information so requested that is proprietary, subject to a third-party confidentiality restriction or to an attorney-client or other privilege) and to grant injunctive relief and enforce specific performance. The Tribunal shall not have the power to award punitive or any other form of indirect or non-compensatory damages, even if such are available under the governing law and even if a court would otherwise be empowered to avoid this limitation on damages to make such an award. If it deems necessary, the Tribunal may propose to the Disputing Members that one or more other experts be retained to assist it in resolving the Dispute. The retention of such other experts shall require the unanimous consent of the Disputing Members, which shall not be unreasonably withheld. The decision of the Tribunal (which shall be rendered in writing) shall be final, nonappealable and binding upon the Members and may be enforced in any court of competent jurisdiction. Each Member hereby consents to the non-exclusive personal jurisdiction and venue of the Washington, D.C., courts for any proceedings in aid of arbitration under this Section, including any request for interim or injunctive relief. Notwithstanding the foregoing consent, the Members may nevertheless seek interim or injunctive relief from any court of competent jurisdiction.

10.5 Arbitration Costs and Expenses. The responsibility for paying the costs and expenses of the arbitration, including compensation to the Tribunal and any experts retained by the Tribunal, shall be borne by the Disputing Member or Disputing Members who is or are the least successful in such process, which shall be determined by the Tribunal by comparing the position asserted by each Disputing Member on all disputed matters taken together to the final decision of the Tribunal on all disputed matters taken together, provided however, that each Disputing Member shall be responsible for the fees and expenses of its respective counsel, consultants and witnesses, unless the Tribunal determines that compelling reasons exist for allocating all or a portion of such costs and expenses to the other Disputing Members.

ARTICLE XI
DISSOLUTION, WINDING-UP AND TERMINATION

11.1 Dissolution. The Company shall dissolve and its affairs shall be wound up on the first to occur of the following events (each a “Dissolution Event”): the unanimous consent of the Members and the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act. No other event shall cause a dissolution of the Company.

11.2 Winding-Up and Termination

(a) Actions of Liquidator. On the occurrence of a Dissolution Event, the Board shall act as liquidator. The liquidator shall proceed diligently to wind up the affairs of the

Company and make final distributions as provided herein and in the Act. The costs of winding up shall be borne as a Company expense. Until final distribution, the liquidator shall continue to operate the Company properties with all of the power and authority of the Members. The steps to be accomplished by the liquidator are as follows:

(i) as promptly as possible after dissolution and again after final winding up, the liquidator shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Company’s assets (including any outstanding unpaid amounts of the Toshiba Committed Contributions), liabilities, and operations through the last calendar Day of the month in which the dissolution occurs or the final winding up is completed, as applicable;

(ii) the liquidator shall discharge from Company funds all of the indebtedness and other debts, liabilities and obligations of the Company (including all expenses incurred in winding up) or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine); and

(iii) all remaining assets of the Company shall be distributed to the Members as follows:

(A) the liquidator may sell any or all property of the Business or a Class, including to Members, and any resulting gain or loss from each sale shall be computed and allocated to the Capital Accounts of the Members for such Class in a manner to cause the Capital Accounts of the Members for such Class to equal, as nearly as possible, the amounts that would be distributable to the Members under the provisions of Section 7.2;

GENERAL PROVISIONS

12.1 Confidential Information

(a) Non-Disclosure; Non-Use. Each Member shall keep confidential (and shall not disclose to any Person) all Confidential Information that is furnished by any other Member or its Affiliates, except that the foregoing restrictions shall not apply to any Confidential Information that (i) is in the public domain at the time of its disclosure or thereafter, other than as a result of a disclosure directly or indirectly by a Member or its Affiliates in contravention of this Agreement, (ii) as to any Member, was known, free of any obligation of confidentiality, by such Member or its Affiliates prior to the execution of this Agreement or (iii) has been independently acquired or developed by a Member or its Affiliates without violating any of the obligations of such Member or its Affiliates under this Agreement. A Member may disclose Confidential Information to the extent that it relates to the Company to its financial and other advisors, lenders or potential acquirers who need to know such Confidential Information for the purpose of evaluating any proposed financing or acquisition transaction (it being understood that such Persons shall be informed by such Member of the confidential nature of the Confidential Information and shall be directed to treat such Confidential Information confidentially and in accordance with this Section 12.1).

(b) Specific Performance. The Members agree that no adequate remedy at law exists for a breach of any of the provisions of this Section 12.1, the continuation of which unremedied will cause the furnishing Member to suffer irreparable harm. Accordingly, the Members agree that the furnishing Member shall be entitled, in addition to other remedies that may be available to them, to immediate injunctive relief from any breach or threatened breach of any of the provisions of this Section 12.1 and to specific performance of their rights hereunder, as well as to any other remedies available at law or in equity.

(c) Survival. The obligations of the Members under this Section 12.1 shall terminate on the second anniversary of the end of the Term.

12.2 Notices. Except as expressly set forth to the contrary in this Agreement, all notices, requests or consents provided for or permitted to be given under this Agreement must be in writing and must be delivered to the recipient in person, by courier or mail or by facsimile (if

followed by courier or mail). A notice, request or consent given under this Agreement is effective on receipt by the Member to receive it; provided, however, that a facsimile that is transmitted after the normal business hours of the recipient shall be deemed effective on the next Business Day. All notices, requests and consents to be sent to a Member must be sent to or made at the addresses or fax number given for that Member on Exhibit A or in the instrument described in Section 3.3 or Section 4.1(b)(i), or such other address or fax number as that Member may specify by notice to the other Member. Any notice, request or consent to the Company must be given to each other Member. Whenever any notice is required to be given by Law, the Certificate or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

12.3 Entire Agreement; Superseding Effect. This Agreement and the Contribution Agreements constitute the entire agreement of the Members and their Affiliates relating to the Company and the transactions contemplated hereby and supersede all provisions and concepts contained in all prior contracts or agreements between the Members or any of their Affiliates with respect to the Company (including the Original Agreement) and the transactions contemplated hereby, whether oral or written.

12.4 Effect of Waiver or Consent. Except as otherwise provided in this Agreement, a waiver or consent, express or implied, to or of any breach or default by any Member in the performance by that Member of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Member of the same or any other obligations of that Member with respect to the Company. Except as otherwise provided in this Agreement, failure on the part of a Member to complain of any act of any other Member or to declare any other Member in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Member of its rights with respect to that default until the applicable statute-of-limitations period has run.

12.5 Amendment or Restatement. This Agreement or the Certificate may be amended or restated only by a written instrument executed (or, in the case of the Certificate, approved) by all of the Members.

12.6 Binding Effect. Subject to the restrictions on Dispositions set forth in this Agreement, this Agreement is binding on and shall inure to the benefit of the Members and their respective successors and permitted assigns.

12.7 Governing Law; Severability. This Agreement is governed by and shall be construed in accordance with the law of the State of Delaware, excluding any conflict-of-laws rule or principle that might refer the governance or the construction of this Agreement to the law of another jurisdiction. If there is a direct conflict between the provisions of this Agreement and any mandatory, non-waivable provision of the Act, such provision of the Act shall control. If any provision of the Act provides that it may be varied or superseded in a limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter. If any provision of this Agreement or the application thereof to any Member or circumstance is held invalid or

unenforceable to any extent, the remainder of this Agreement and the application of that provision to the other Member or circumstances is not affected thereby and the Members shall negotiate in good faith to replace that provision with a new provision that is valid and enforceable and that puts the Members in substantially the same economic, business and legal position as they would have been in if the original provision had been valid and enforceable.

12.8 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Member shall execute and deliver any additional documents and instruments and perform any additional acts that may be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions.

12.9 Waiver of Certain Rights. Each Member irrevocably waives any right it may have to maintain any action for dissolution of the Company or for partition of the property of the Company.

12.10 Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signing parties had signed the same document. All counterparts shall be construed together and constitute the same instrument.
