6.2 Authority for Agreement; Non-Contravention.

(a) Authority. Investor has the requisite power and authority to enter into this Agreement and to consummate the Transactions. The execution and delivery of this Agreement and the consummation of the Transactions have been duly and validly authorized by all necessary company action and no other corporate or member proceedings or actions (or their equivalents) are necessary on the part of Investor to authorize and consummate this Agreement and the Transactions. This Agreement has been duly executed and delivered by Investor, and constitutes the legal, valid and binding obligations of Investor, enforceable against Investor in accordance with their respective terms, subject to the qualifications that enforcement of the rights and remedies created hereby are subject to Equitable Qualifications.

(b) No Conflict. Neither the execution and delivery by Investor of this Agreement nor the performance by Investor of its obligations hereunder, nor the consummation by Investor of the Transactions will (i) violate any provision of the Charter Documents of Investor, (ii) conflict with, or result in a breach of any term, covenant, condition or provision of, or constitute a default (with or without notice or lapse of time or both) under, or result a penalty or in the creation or imposition of any Lien (other than a Permitted Lien) upon any material Assets of Investor pursuant to, or give rise to any right of termination, cancellation or acceleration under, the terms of any material Contract to which Investor is a party or by which Investor or any of its material Assets are bound, which would reasonably be expected to adversely affect Investor’s ability to carry out its obligations under this Agreement, (iii) conflict with or result in a material violation or breach of any term or provision of any Laws applicable to Investor or any of its respective material Assets, or (iv) require the consent or approval of, filing with, or notice to any Person which, if not obtained, would prevent Investor from performing its obligations under this Agreement.

6.3 Litigation and Audits. In each case as it relates to the Transactions, and except as it would not reasonably be expected to result in a material adverse effect on Investor’s ability to perform its obligations hereunder, (i) there is no investigation by any Governmental Entity with respect to Investor that is pending or, to the Knowledge of Investor, threatened, nor

(a) Investment Purposes. Investor is buying the Investor Interests for its own account, for investment purposes only and not with a view toward, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the Investor Interests, in violation of the federal securities Laws or any applicable foreign or state securities Law.

The Parties acknowledge and agree that JBIC and NEXI are separate entities that are not controlled by Investor, and there can be no guaranty that such efforts by Investor will result in such a conditional commitment or a financing by JBIC, or such credit insurance from NEXI, on terms or conditions or at a time satisfactory to the Parties or NINA Investments or otherwise, and Investor shall have no liability hereunder if such commitment, financing, or credit insurance is not timely provided by JBIC or NEXI on satisfactory terms and conditions or otherwise is not provided.

10.2 Indemnification Obligations — NINA.

Subject to the terms and conditions of this Article X, from and after the Initial Closing, NINA shall indemnify and hold harmless Investor and its Subsidiaries, officers and directors, agents and Affiliates (individually and collectively, the “TEPCO Group”) against all Losses resulting from, imposed upon or incurred by any member of the TEPCO Group directly or indirectly arising out of any of the following:

(a) any failure of any of the representations or warranties of NINA contained in Article IV or NINA Holdings contained in Article V to be true and correct at and as of the Agreement Date and the Initial Closing Date, or of any of the representations or warranties of either NINA Party contained in any certificate delivered to Investor at the Initial Closing pursuant to Section 2.5(a), except for such representations and warranties that are made at and as of an earlier date, in which case at and as of such earlier date;

(b) any breach of any of the covenants, obligations or agreements of NINA Holdings contained in Section 7.6; or

(c) any breach of any of the covenants, obligations or agreements of either NINA Party contained in this Agreement (other than Section 7.6).

NINA hereby fully and forever waives and relinquishes any right it may have (i) to be subrogated to the rights of Investor against NINA Holdings in respect of any amounts paid or obligation performed by NINA pursuant to this Article X, and (ii) against NINA Holdings for reimbursement, indemnity, contribution, or any similar legal or equitable right with respect to


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

any such amount or obligation. The indemnification obligations of NINA under this Article X are primary obligations of NINA, and not those of a guarantor or surety, and are absolute and independent of those of NINA Holdings, and Investor may maintain a separate action or actions against NINA to enforce its indemnification obligation under this Article X. NINA expressly waives (i) diligence, presentment, and protest, (ii) notice of acceptance of this indemnity by Investor, (iii) demand for payment of any of such obligations, and (iv) any claim or defense that Investor shall have impaired any right of NINA against NINA Holdings, any other guarantor of any such obligations, or any other Person, by way of reimbursement, subrogation or otherwise. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not affect the liability of Indemnitor hereunder: (a) any dissolution of either of the NINA Parties, or the combination or consolidation of either of the NINA Parties into or with another entity or any transfer or disposition of any assets of either of the NINA Parties, (b) any bankruptcy, insolvency, reorganization, dissolution, liquidation or other similar proceeding relating to either of the NINA Parties; (c) either of the NINA Parties ceasing to be a person or entity controlled by, controlling or under common control with NRG, (d) the absence of any notice to, or knowledge by, NINA of the existence or occurrence of any of the matters set forth in the foregoing clauses, or (e) any other circumstance whatsoever that might otherwise constitute a legal or equitable defense available to, or discharge of, a surety or a guarantor.

10.3 Indemnification Obligations — Investor.

Subject to the terms and conditions of this Article X, from and after the Initial Closing Investor shall indemnify and hold harmless NINA, NINA Holdings and their respective Subsidiaries, officers and directors, agents and Affiliates (individually and collectively, the “NINA Group”; provided, in no event shall any member of the TEPCO Group be deemed a member of the NINA Group) against all Losses resulting from, imposed upon or incurred by any member of the NINA Group directly or indirectly arising out of any of the following:

(a) any failure of any of Investor’s representations or warranties contained in Article VI of this Agreement to be true and correct at and as of the Agreement Date and the Initial Closing Date, or of any of the representations or warranties of Investor contained in any certificate delivered to NINA Holdings at the Initial Closing pursuant to Section 2.5(b), except for such representations and warranties that are made at and as of an earlier date, in which case at and as of such earlier date; or

(b) any breach of any of Investor’s covenants, obligations or agreements contained in this Agreement.

10.4 Limitations on Indemnification Obligations; Liability Cap.

(a) By NINA. Except as set forth below, NINA shall not be required to indemnify any member of the TEPCO Group with respect to any claim for indemnification resulting from or arising out of matters described in Section 10.2(a) or Section 10.2(b) except to the extent that (i) any such claim is in an amount in excess of ^** (the “De Minimis Amount”),


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

and (ii) the aggregate amount of all claims by members of the TEPCO Group in excess of the De Minimis Amount exceeds ^** (the “Indemnity Threshold”), and then the TEPCO Group will be entitled to recover all Losses except for Losses from claims that may not be asserted under Section 10.4(a)(i); provided, that NINA’s aggregate liability under Section 10.2(a) and Section 10.2(b) shall not exceed (x) if the Option Closing does not occur, other than as a result of a breach of NINA Holdings’ obligation to consummate the Option Closing under Section 8.6 (a “Holdings Closing Breach”), ^**, or (y) if the Option Closing occurs, or if the Option Closing does not occur as a result of a Holdings Closing Breach, ^** (the “Indemnity Cap”); provided, further, that NINA’s liability under Section 10.2(a) for breaches of representations and warranties contained in Section 4.1(a), Section 4.1(c), Section 4.2, Section 5.1(a), Section 5.1(d), Section 5.2, Section 5.3(a), Section 5.3(b), Section 5.3(c), Section 5.3(d), Section 5.6 or Section 5.11 shall not be subject to any of the foregoing limitations and shall not count toward any such limitations. For the avoidance of doubt, any claims by the TEPCO Group for Losses arising from the matters specified in Section 10.2(c) shall not be subject to any of the limitations set forth in the preceding sentence. Notwithstanding anything herein to the contrary, NINA’s aggregate liability under this Agreement shall not exceed the Investor Aggregate Investment Amount.

(b) By Investor. Except as set forth below, Investor shall not be required to indemnify any member of the NINA Group with respect to any claim for indemnification resulting from or arising out of matters described in Section 10.3(a) except to the extent that (i) any such claim is in an amount in excess of the De Minimis Amount, and (ii) the aggregate amount of all claims by members of the NINA Group in excess of the De Minimis Amount exceeds the Indemnity Threshold, and then the NINA Group will be entitled to recover all Losses except for Losses from claims that may not be asserted under Section 10.4(b)(i); provided, that Investor’s maximum aggregate liability under Section 10.3(a) shall not exceed the Indemnity Cap; provided, further, that Investor’s liability under Section 10.3(a) for breaches of representations and warranties contained in Section 6.1, Section 6.2 or Section 6.4 shall not be subject to or count toward the De Minimis Amount or the Indemnity Threshold. For the avoidance of doubt, any claims by the NINA Group for Losses arising from the matters specified in Section 10.3(b) shall not be subject to any of the limitations set forth in the preceding sentence. Notwithstanding anything herein to the contrary, Investor’s aggregate liability under this Agreement shall not exceed the Investor Aggregate Investment Amount.

(c) No Consequential or Punitive Damages. Notwithstanding any other provision of this Agreement, neither NINA nor Investor shall by way of indemnification for Losses or otherwise be liable to any of the TEPCO Group or the NINA Group, respectively, for any consequential, exemplary, special, incidental or punitive damages claimed by any of such TEPCO Group or NINA Group (as applicable) under the terms of or due to any breach of this Agreement, including, but not limited to, loss of revenue, income, or profits, cost of capital, or loss of business reputation or opportunity, except that this limitation shall not apply to any Third-Party Claims for consequential, exemplary, special, incidental or punitive damages.


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

(d) Losses Net of Insurance. The amount of any Loss for which indemnification is provided under Section 10.2 or Section 10.3 shall be net of (i) any amounts recovered by the Indemnitee pursuant to any indemnification by or indemnification agreement with any other Person, and (ii) any insurance proceeds or other cash receipts or sources of reimbursement received by the Indemnitee as an offset against such Loss (each source of recovery referred to in clauses (i) and (ii), a “Collateral Source”). If the amount to be netted hereunder in connection with a Collateral Source from any payment required under Section 10.2 or Section 10.3 is received after payment by the Indemnitee of any amount otherwise required to be paid to an Indemnitee pursuant to this Article X, the Indemnitee shall repay to the Indemnitor, promptly after such receipt, any amount that the Indemnitee would not have had to pay pursuant to this Article X had such receipt occurred at the time of such payment.

10.5 Indemnification Process for Claims.

(a) Notice to Collect. To collect the amount of any claim for which a member of the TEPCO Group or the NINA Group seeks indemnification under this Article X, including indemnification for claims that are brought by third parties against any such Person (a “Claim”), the indemnified Person (the “Indemnitee”) shall give the indemnifying Party (the “Indemnitor”) notice of such Claim. Such notice shall contain a summary of the basis for the Claim and a reasonable estimate of the amount of Losses suffered or likely to be suffered by the Indemnitee as a consequence thereof. If the Indemnitor does not dispute the basis or amount of any Claim within thirty (30) days of receiving notice thereof, the Indemnitee shall have the right to recover the applicable indemnity amount through a wire transfer of funds to such account as may be designated by such Indemnitee. If any Indemnitor disagrees in good faith with the basis of the Indemnitee’s Claim or the amount of Losses suffered by the Indemnitee in connection therewith, then within twenty (20) days of receiving notice thereof, such Indemnitor, as applicable, shall give notice to the Indemnitee of such disagreement.

(b) Third-Party Claims. With respect to each third-party Claim for which a member of the NINA Group or the TEPCO Group seeks indemnification under this Article X (collectively, “Third-Party Claims”), the Indemnitee shall give written notice to the Indemnitor of the Third-Party Claim within thirty (30) days of the first receipt by the Indemnitee of notice of such Third-Party Claim; provided, that failure to give such notice promptly to the Indemnitor shall not relieve or limit the obligations of the Indemnitor except to the extent that the Indemnitor shall have been materially prejudiced by such failure to give such notice, in which case the Indemnitor shall be relieved of its obligations under this Article X to the extent of such material prejudice. The Indemnitor shall have the right to assume the defense of any such Third-Party Claim at its own cost and expense; provided, that counsel for the Indemnitor conducting the defense of such Third-Party Claim shall be subject to the approval of Indemnitee (whose approval shall not be unreasonably withheld). If the Indemnitor chooses to defend or prosecute a Third-Party Claim, the Indemnitee shall cooperate in the defense or prosecution thereof, which cooperation shall include, to the extent reasonably requested by the Indemnitor and at the cost of the Indemnitor, (i) the retention, and the provision to the Indemnitor, of records and information reasonably relevant to such Third-Party Claim, and (ii) making directors, officers, managers, executives, employees, consultants and agents of the Indemnitee and its Affiliates available on a mutually convenient basis to provide additional information and explanation of any materials provided hereunder. The Indemnitee may participate in, but not control, such defense at its own

expense; provided, that the Indemnitor shall pay such expense if the Indemnitee shall have reasonably concluded that there is a substantial probability of a conflict between the positions of the Indemnitor and the Indemnitee in conducting the defense of any such Third-Party Claim or that there may be legal defenses available to the Indemnitee that are different from or additional to those available to the Indemnitor. No Indemnitee shall settle any Third-Party Claim without the consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed. If the Indemnitor wishes to enter into a settlement with respect to a Third-Party Claim, the Indemnitee shall cooperate in such settlement; provided, that such settlement (x) does not provide for injunctive relief or similar equitable remedies against the Indemnitee, and (y) includes, as an unconditional term thereof, the giving by the third party to the Indemnitee of a release from all liability in respect of such Third-Party Claim. If the Indemnitor elects not to control or conduct the defense or prosecution of a Third-Party Claim, the Indemnitor nevertheless shall have the right to participate in the defense or prosecution of any Third-Party Claim and, at its own expense, to employ counsel of its own choosing for such purpose.

10.6 Specific Performance. In addition to any other remedies which the Parties may have at law or in equity, the Parties hereby acknowledge that the transactions contemplated under this Agreement are unique, and that the harm to Investor on the one hand, or the NINA Parties, on the other hand, resulting from breaches by the NINA Parties or Investor, respectively, of their obligations cannot be adequately compensated by damages. Accordingly, the Parties agree that Investor and the NINA Parties shall have the right to have all obligations, undertakings, agreements, covenants and other provisions of this Agreement specifically performed by the NINA Parties, on the one hand, or by Investor, on the other hand, as the case may be, and that Investor or the NINA Parties, as the case may be, shall have the right to obtain an order or decree of such specific performance in any of the courts of the United States of America or any state or other political subdivision thereof; provided, that neither the NINA Parties, on the one hand, nor Investor, on the other hand, shall be required to post any guaranty, letter of credit, bond or other security to obtain an order or decree of such specific performance.

10.7 Exclusive Remedy. Notwithstanding any other provision of this Agreement to the contrary or any remedies that might otherwise be available under Law (other than claims based on fraud) the remedies set forth in this Article X shall constitute the sole and exclusive remedies of the Parties after the Initial Closing for any claims arising under this Agreement or the certificates to be delivered at the Initial Closing (i) for breach of the representations and warranties set forth herein or therein, or (ii) for breach prior to the Initial Closing of the covenants set forth in Section 7.6.

10.8 No Recourse. No Person other than the Parties shall be liable for the payment of any amount due hereunder or for the performance of any other obligation (including the breach of any representation or warranty or any indemnification obligation) hereunder, and the sole recourse of (i) the NINA Parties for satisfaction of such obligations of Investor shall be against Investor and its assets and not against any other Person, and (ii) of Investor for the satisfaction of such obligations of the NINA Parties shall be against the NINA Party undertaking such obligation and its assets and not against any other Person; provided, that nothing in this Section 10.8 shall limit or otherwise prejudice in any way the right of any Party to proceed against any Person with respect to the enforcement of such Person’s obligations (or the enforcement of such Party’s rights) under any other agreement to which it is a party, including any Related Agreement.

10.9 Adjustments to Initial Investment Amount. The Parties hereby agree that any and all indemnity payments made pursuant to this Article X shall, to the maximum extent permitted by applicable Law, be treated for all Tax purposes as an adjustment to the Initial Investment Amount.

ARTICLE XI

MISCELLANEOUS

11.1 Amendments and Supplements. This Agreement may be amended or supplemented only by an instrument in writing signed by each Party.

11.2 Waiver. The terms and conditions of this Agreement may be waived only by a written instrument signed by the Party waiving compliance. The failure of any Party hereto to enforce at any time any of the provisions of this Agreement shall in no way be construed to be a waiver of any such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of such Party thereafter to enforce each and every such provision. No waiver of any breach of or non-compliance with this Agreement shall be held to be a waiver of any other or subsequent breach or non-compliance. Except as otherwise expressly provided in this Agreement, the rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies that any Party may otherwise have at law or in equity.

11.3 Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the substantive laws of the State of New York, without regard to its principles of conflicts of laws other than Section 5-1401 of the New York General Obligations Law.

11.4 Resolution of Disputes.

(a) 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 among the Parties 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 effect except as modified herein.

(b) Negotiation to Resolve Disputes. If a Dispute arises out of or relates to this Agreement, either the NINA Parties, on the one hand, or Investor, on the other hand, shall give notice to the other Parties that it intends to initiate the dispute resolution procedures set forth herein. Promptly upon receipt of such notice, each Party shall refer such Dispute to a senior executive officer (“SEO”) of such Party. 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 of the NINA Parties, on the one hand, and Investor, on the other hand, are unable to resolve the Dispute on or before the thirtieth (30th) day after such notice, either the NINA Parties, on the one hand, or Investor, on the other hand, may commence arbitration under this Section 11.4 by notifying the other Parties (an “Arbitration Notice”).

(i) Any arbitration conducted under this Section 11.4 shall be heard by three (3) arbitrators (each an “Arbitrator” and collectively the “Tribunal”) selected in accordance with this Section 11.4. Each Party and any proposed Arbitrator shall, as soon as practicable, disclose to the other Parties any business, personal or other relationship or affiliation that may exist between a Party and the proposed Arbitrators. The Parties 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.

(ii) Except as provided for in this Section 11.4, the Tribunal shall be appointed according to the Rules. In the Arbitration Notice, the Party or Parties (whether Investor or the NINA Parties, as applicable) requesting arbitration shall nominate one Arbitrator. The Parties or Party (whether the NINA Parties or Investor, as applicable) named as respondent by the claimant shall nominate one Arbitrator. Within thirty (30) days of the appointment of the second Arbitrator, the two (2) Party-appointed Arbitrators shall appoint a third Arbitrator who shall chair the arbitration. Within seven (7) Days of receiving this list, each Party shall provide to CPR a ranking of the potential Arbitrators on such list showing such Party’s order of preference among such proposed Arbitrators, with the NINA Parties submitting one common ranked list. The CPR shall then appoint all three (3) Arbitrators as it shall determine in its discretion but taking into account to the extent practical the preferences of the Parties.

(d) 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 ^** 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 Party 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 Parties 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 Parties, which shall not be unreasonably withheld. The decision of the Tribunal (which shall be rendered in writing) shall be final, non-appealable and binding upon the Parties and may be enforced in any court of competent jurisdiction. Each Party 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 11.4, including any request for interim or injunctive relief. Notwithstanding the foregoing

consent, the Parties may nevertheless seek interim or injunctive relief from any court of competent jurisdiction.

(e) 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 NINA Parties, on the one hand, or Investor, on the other hand, whichever is the least successful in such process, which shall be determined by the Tribunal by comparing the position asserted by the NINA Parties, on the one hand, or Investor, on the other hand, on all disputed matters taken together to the final decision of the Tribunal on all disputed matters taken together; provided, that each Party 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 NINA Parties, on the one hand, or Investor, on the other hand.

11.5 Notice. Except as expressly set forth to the contrary in this Agreement, all notices, requests, consents, or other communications 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, mail, electronic mail (with receipt confirmed personally by the recipient (and not by automatic confirmation of receipt)) or facsimile (if followed by courier or mail). A notice, request, consent, or communication given under this Agreement is effective on receipt by the Party to receive it; provided, that a notice, request, consent, or communication given by electronic mail shall be deemed effective upon being sent in the local jurisdiction from which such electronic mail is being sent, subject to confirmation of receipt by the recipient as set forth in the preceding sentence.

11.6 Entire Agreement. This Agreement (including the Schedules and Exhibits attached hereto), the Confidentiality Agreement, and the Related Agreements constitute the entire agreement among the Parties with respect to the subject matter hereof and supersede all other prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof, including the Letter of Intent but excluding the Confidentiality Agreement, which shall survive until the Initial Closing.

11.7 Binding Effect; Assignability. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. This Agreement is not intended to confer upon any Person other than the Parties (and such Parties’ respective successors and permitted assigns) any rights or remedies hereunder, except as otherwise expressly provided herein. No Party shall assign any of its rights or delegate any of its obligations under this Agreement to any Person (other than, in the case of Investor, to its Wholly Owned Affiliate (as defined in the Operating Agreement) who is at least as creditworthy as the Investor (as reasonably determined by the NINA Parties)) without the prior written consent of the other Parties. Any purported assignment of rights or delegation of obligations in contravention of this Section 11.7 shall be void ab initio.

11.8 Validity. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, each of which shall remain in full force and effect.

11.9 Counterparts. This Agreement may be executed and delivered in one or more counterparts, all of which together shall constitute one and the same agreement. This Agreement may be delivered by facsimile transmission.

11.10 Time is of the Essence. The Parties acknowledge that time is of the essence with respect to this Agreement. If any date specified in this Agreement or the Related Agreements for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

11.11 No Relationship. Nothing in this Agreement or the Related Agreements creates or is intended to create an association, trust, partnership, joint venture, joint-employer, or any other entity or similar legal relationship among the Parties, or impose a trust, partnership or fiduciary duty, obligation, or liability on or with respect to the NINA Parties or Investor. None of the NINA Parties, on the one hand, nor Investor, on the other hand, is or shall act as or be the agent or Representative of Investor or either of the NINA Parties, respectively.

11.12 Construction of Agreement. This Agreement and the Related Agreements shall be construed without regard to the identity of the Person who drafted the various provisions of the same. Each and every provision of this Agreement and the Related Agreements shall be construed as though the Parties participated equally in the drafting of the same. Consequently, the Parties acknowledge and agree that any rule of construction that a document is to be construed against the drafting party shall not be applicable either to this Agreement or the Related Agreements.

WHEREAS, Guarantor acknowledges that it will receive direct and indirect benefits from Beneficiary entering into and performing its obligations under the Investment Agreement and, accordingly, Guarantor is willing to guarantee certain obligations of NINA to Beneficiary under the Investment Agreement, subject to the terms, conditions and limitations contained herein.

NOW, THEREFORE, to induce Beneficiary to enter into and perform its obligations under the Investment Agreement, and for other good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged, the parties hereto hereby agree as follows:

Section 1. Guaranty. Guarantor hereby absolutely, irrevocably and unconditionally guarantees to Beneficiary, as primary obligor and not merely as surety, the due and punctual payment and performance of the obligations of NINA under Section 10.2(a) and 10.5 of the Investment Agreement, but only with respect to those representations and warranties of NINA contained in Article IV of the Investment Agreement and NINA Holdings contained in Sections 5.1, 5.2, 5.3, 5.5, 5.6, 5.9, 5.10, 5.11, 5.13(a), 5.13(c), 5.14(a), 5.14(d), 5.14(e), 5.16, 5.17(a) and 5.21 of the Investment Agreement (which representations and warranties, for purposes of this Limited Guaranty, shall be deemed to exclude any representation and warranty regarding STPNOC (as defined in the Investment Agreement), except with respect to the representations and warranties in Sections 5.5 and 5.16) (such obligations, the “Guaranteed Obligations”); provided, that Guarantor’s liability under this Guaranty shall not exceed the sum

^**; provided, further, that the obligations of Guarantor under this Guaranty are conditioned on the occurrence of the Initial Closing under and as defined in the Investment Agreement, and in the event the Investment Agreement is terminated in accordance with its terms, this Guaranty shall automatically terminate and be of no further force and effect. This Guaranty is a guaranty of payment and performance and not merely of collection.

Section 2. Guaranty Absolute and Independent. Guarantor’s obligations under this Guaranty are absolute and are independent of those of the NINA Parties and Beneficiary may maintain a separate action or actions against Guarantor to enforce this Guaranty. Accordingly, Beneficiary shall not be obligated or required before enforcing this Guaranty against Guarantor to: (i) commence any suit or other proceeding against either of the NINA Parties or any other person, or any other security for the Guaranteed Obligations, in any court or other tribunal, or (ii) make any claim in any bankruptcy, insolvency, reorganization, liquidation, dissolution, or similar proceedings affecting either of the NINA Parties (whether voluntary or involuntary); and the failure of Beneficiary to so act or so file shall not affect or impair Guarantor’s obligations hereunder.

Section 3. Continuing Guaranty. This Guaranty is a continuing guarantee and shall apply to all Guaranteed Obligations whenever arising, and shall remain in full force and effect until such time as all the Guaranteed Obligations have been discharged finally and in full.

Section 4. Waivers. Guarantor expressly waives (i) diligence, presentment, and protest, (ii) notice of acceptance of this Guaranty by Beneficiary, and all other notices whatsoever, (iii) demand for payment or performance of any of the Guaranteed Obligations, and (iv) any claim or defense that Beneficiary shall have impaired any right of Guarantor against either of the NINA Parties, any other guarantor of any of the Guaranteed Obligations, or any other person or entity, by way of reimbursement, subrogation or otherwise. Without limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not affect the liability of Guarantor hereunder: (a) any dissolution of either of the NINA Parties, or the combination or consolidation of either of the NINA Parties into or with another entity or any transfer or disposition of any assets of either of the NINA Parties, (b) any bankruptcy, insolvency, reorganization, dissolution, liquidation or other similar proceeding relating to either of the NINA Parties; (c) either of the NINA Parties ceasing to be a person or entity controlled by, controlling or under common control with Guarantor, (d) the absence of any notice to, or knowledge by, Guarantor of the existence or occurrence of any of the matters set forth in the foregoing clauses, or (e) any other circumstance whatsoever that might otherwise constitute a legal or equitable defense available to, or discharge of, a surety or a guarantor.

Section 5. Effect of Amendments. Guarantor agrees that Beneficiary and the NINA Parties may modify, amend and supplement the Investment Agreement and that Beneficiary may delay or extend the date on which any payment must be made pursuant to the

Section 7. Subrogation; Subordination. Guarantor hereby fully and forever waives and relinquishes any right it may have (i) to be subrogated to the rights of Beneficiary against either of the NINA Parties in respect of any amounts paid or obligation performed by Guarantor pursuant to this Guaranty, and (ii) against either of the NINA Parties for reimbursement, indemnity, contribution, or any similar legal or equitable right with respect to any such amount or obligation.

The execution, delivery, and performance of Guaranty have been duly and validly authorized by all necessary corporate action and no other corporate or shareholder proceedings or actions (or their equivalents) are necessary on its part to authorize and consummate this Guaranty.

MEMBERSHIP UNITS; MEMBERS

3.1 Membership Units. The Company shall have one class of membership units (the “Membership Units”). The Membership Units represent a Member’s share of the income, gains, deductions, credits, profits and similar items, and such Member’s right to receive distributions, from, associated with or allocable to the Company’s investment in NINA Investments LLC and the STP Entities and all liabilities, losses, costs and expenses from, associated with or allocable to such investment and/or to the development, permitting, engineering, procurement, construction, ownership, financing and operation of the Project (the “Business”). Each Membership Unit shall be a “security” for purposes of, as defined in, and governed by, Article 8 of the Uniform Commercial Code and shall be evidenced by a Membership Unit certificate in the form of Exhibit D. Each such certificate shall bear a legend substantially in the following form:

“THIS CERTIFICATE EVIDENCES MEMBERSHIP UNITS REPRESENTING A MEMBERSHIP INTEREST IN NINA INVESTMENTS HOLDINGS LLC AND SHALL BE A

SECURITY WITHIN THE MEANING OF, AND GOVERNED BY, ARTICLE 8 OF THE UNIFORM COMMERCIAL CODE.”

The Membership Units shall be adjusted, and new or additional certificates shall be issued, including to reflect any adjustments made pursuant to Section 6.3(a) to Membership Units held by the Members, as necessary from time to time so that such Membership Units are owned by the Members in proportion to their Capital Contributions.

3.2 Members as of the Effective Date. Each Member executing this Agreement as of the Effective Date has been admitted as a Member on or prior to the Effective Date. Each Member has been issued the number of Membership Units, and has the Membership Percentage as of the Effective Date (rounded to the nearest 1/1,000^th of a percent), as set forth opposite its name on Exhibit A. If and when the Company issues additional Membership Units or a Member Disposes of all or a portion of its Membership Units or any Person ceases to be a Member pursuant to, and in accordance with, the terms and conditions of this Agreement, then upon such issuance, Disposition or cessation of membership, as applicable, the Company shall amend Exhibit A and the records of the Company, as appropriate, to reflect such issuance, Disposition or cessation of membership and deliver to each Member, within a reasonable time thereafter, a copy of Exhibit A, as amended.

The provisions of this Section 3.3 shall not apply to Dispositions of Membership Units or admissions of Assignees in connection therewith, such matters being governed by Article IV.

3.4 Ceasing to Be a Member. Any Person admitted as a Member pursuant to Section 3.2 or 3.3 or Article IV shall cease to be a Member, and shall cease to have the rights of a Member, under this Agreement at such time such Person no longer owns, beneficially and of record, any Membership Units, but such Person shall remain bound by the terms of Article X and Article XII and shall remain liable under this Agreement to the extent expressly set forth herein.

In the case of any Member other than NINA, such Member is Completely Controlled by its Parent as set forth opposite its name on Exhibit A, and in the case of NINA, such Member is Controlled by its Parent as set forth opposite its name on Exhibit A.

(b) Execution and Delivery; Enforceability.

(c) Non-Contravention. Such Member’s authorization, execution, delivery, and performance of this Agreement does not and will not (i) conflict with, or result in a breach, default or violation of, (A) the organizational documents of such Member, (B) any contract or agreement to which such Member is a party or is otherwise subject or (C) any Law, order, judgment, decree, writ, injunction or arbitral award to which such Member is subject or (ii) require any consent, approval or authorization from, filing or registration with, or notice to, any Governmental Authority or other Person, unless such requirement has already been satisfied.

(d) Investment Purpose.

Such Member has not authorized or dealt with any agent, broker, Person or firm acting on behalf of such Member or the Company, who is, or shall be, entitled to any broker’s fees, finder’s fees or commissions in connection with this Agreement or any of the transactions contemplated hereby.

No Member has the right or power to withdraw or resign from the Company without the prior written consent of each Member having or deemed as having the Minimum Threshold Percentage (other than in the event that such Member ceases to hold any Membership Units); no Member shall be liable for the debts, obligations or liabilities of the Company; and no Member may be expelled from the Company (other than in the event that such Member ceases to hold any Membership Units).

The business transacted at any such meeting shall be limited to that stated in the notice of meeting. All notices of a meeting must state the time and place of the meeting and be given on or before the fifth (5^th) Business Day before the meeting, or, in the case of an emergency, such shorter period as the Board may determine appropriate under the circumstances. All notices must specify, as applicable, the purpose of the meeting or the matter requiring the Required Member Approval to be considered at the meeting.

On any matter that is to be voted on, consented to or approved by the Members, the Members may take such action without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, are signed by the Members having not less than the minimum voting percentage 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; provided, that the non-consenting Members shall be given prompt notice after the requisite number of Members sign such consent.

3.8 Right of First Offer. Subject to the terms and conditions specified in this Section 3.8, the Company hereby grants to each Member having or deemed as having the Minimum Threshold Percentage a right of first offer with respect to future sales by the Company of its Membership Units or other debt or equity securities of the Company convertible into or exchangeable or exercisable for any Membership Units (collectively, “New Securities”). Each time the Company proposes to offer any New Securities, the Company shall first make an offering of such New Securities to each Member in accordance with the following provisions:

(a) Issuance Notice. The Company shall deliver a notice (the “Issuance Notice”) to the Members stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms upon which it proposes to offer such New Securities.

(b) Election. Each Member may elect, by notice to the Company on or before the ^** Day after the Issuance Notice (the “Election Notice”), to purchase or obtain, at the price and on the terms specified in the Issuance Notice, all or any portion of the New Securities. In the event that the Company shall have received Election Notices which collectively offer to purchase more New Securities than the Company is proposing to sell, then the New Securities shall be allocated among the Members electing to purchase or obtain New Securities pro-rata in accordance with their respective Membership Percentages (such pro-rata share to be determined by including only the Membership Percentages of such electing Members).


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

(c) Expiration. If all New Securities that Members are entitled to purchase or obtain pursuant to Section 3.8(b) are not elected to be purchased or obtained as provided in Section 3.8(b), the Company may, during the ^** Day period following the expiration of the period provided in Section 3.8(b), offer the unsubscribed portion, if any, of such New Securities to any Person or Persons at a price not less than and upon terms not materially more favorable to the offeree than the price and terms, respectively, that were specified in such Issuance Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within ^** Days of the execution thereof (or if regulatory approvals are required, such as the prior written consent of the NRC or the DOE, within ^** Days after the date on which all such approvals are obtained), the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Members by delivery of an Issuance Notice in accordance with this Section 3.8.

(d) Exceptions. The right of first offer in this Section 3.8 shall not be applicable to (i) the issuance or sale of Membership Units pursuant to the TEPCO Investment Agreement, including the issuance of Membership Units in connection with the TEPCO Member’s exercise of the Option pursuant to the TEPCO Investment Agreement, (ii) the issuance or sale of Membership Units to new Members admitted to the Company to satisfy any shortfalls in Capital Calls pursuant to and in accordance with Section 6.3, (iii) the issuance or sale of New Securities in an IPO or (iv) Dispositions of Membership Units as a result of TANE exercising its rights under the Toshiba Credit Agreement and the other Loan Documents.

3.9 Business of the Subsidiaries of the Company. Concurrently with the execution of this Agreement, the Company shall cause the limited liability company agreement of: (a) Nuclear Innovation North America Investments LLC, a Delaware limited liability company (“NINA Investments LLC”), to be amended to provide that NINA Investments LLC shall not conduct any business other than the Business and any other business or activity that now or in the future may be necessary, incidental, proper, advisable, or convenient to conduct such Business; and (b) each of NINA Texas 3 LLC, a Delaware limited liability company (“NINA Texas 3”) and NINA Texas 4 LLC, a Delaware limited liability company (“NINA Texas 4”), to be amended to provide that NINA Texas 3 and NINA Texas 4 shall not conduct any business other than business related to the development, permitting, engineering, procurement, construction, ownership, financing and operation of STP 3 or STP 4, respectively, and any other business or activity that now or in the future may be necessary, incidental, proper, advisable, or convenient to conduct such business.

ARTICLE IV
DISPOSITIONS OF MEMBERSHIP UNITS

4.1 Requirements for Dispositions.

(a) Compliance with Article IV. A Member may not Dispose of all or any portion of its Membership Units except in accordance with this Article IV. Any attempted Disposition of any Membership Units, other than in accordance with this Article IV, shall be, and is hereby declared, null and void ab initio.

(b) General Requirements for Dispositions of Membership Units. Any Member Disposing of all or any portion of its Membership Units (a “Disposing Member”) and its Assignee, if applicable, shall cause the requirements in this Article IV to be met in connection with such Disposition and, if applicable, the admission of such Assignee as a Member, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with.

(i) The following documents must be delivered to the Company and each Member other than the Disposing Member (each, a “Nondisposing Member”) and must be satisfactory, in form and substance, to the Board in its reasonable discretion:

(A) a copy of the instrument pursuant to which the Disposition is to be effected;

(B) an instrument, executed by the Disposing Member and its Assignee, containing the following information and agreements, to the extent they are not contained in the instrument described above: (1) the notice address of the Assignee; (2) if the Assignee has a Parent, the name of the Parent; (3) the Assignee’s ratification of this Agreement and agreement to be bound by it, the Assignee’s assumption of all obligations of the Disposing Member from and after the date of the Disposition and the Assignee’s confirmation that the representations and warranties in Section 3.5 are true and correct with respect to it; (4) representations and warranties by the Disposing Member and its Assignee that (a) the Disposition and admission are being made in accordance with all applicable Laws (including that the Disposition does not require any approval of the NRC or any other Governmental Authority or that the Disposing Member or its Assignee has obtained any such approval at their own cost and expense without imposing any material regulatory burden or adverse regulatory or other consequences on the Company or the Nondisposing Members) and (b) the matters covered in the legal opinions described in subsections 4.1(b)(i)(C) and 4.1(b)(i)(D) are true and correct;

(C) unless the Membership Units subject to the Disposition are registered under the Securities Act and any applicable state securities Law, a favorable opinion of the Company’s legal counsel, or of other legal counsel acceptable to the Board in its reasonable discretion, to the effect that the

Disposition and admission are being made pursuant to a valid exemption from registration under those Laws and in accordance with those Laws; and

(D) a favorable opinion of the Company’s legal counsel, or of other legal counsel acceptable to the Board in its reasonable discretion, to the effect that the Disposition would not result in the Company’s being considered to have terminated within the meaning of Code Section 708;

provided, however, that the Board, in its sole and absolute discretion, may waive the foregoing subsections 4.1(b)(i)(C) and 4.1(b)(i)(D); and provided, further, that if such Disposition is a result of a Change of Control, the Disposing Member shall only be required to provide the Company and each Nondisposing Member with (1) the name of the Disposing Member’s Parent after such Change of Control is consummated, (2) a summary of the material terms of the instrument pursuant to which the Disposition is to be effected and (3) an instrument executed by the Disposing Member containing representations and warranties by the Disposing Member that the Disposition is being made in accordance with all applicable Laws (including that the Disposition does not require any approval of the NRC or any other Governmental Authority or that the Disposing Member or its new Parent and/or Affiliates have obtained any such approval at their own cost and expense without imposing any material regulatory burden or adverse regulatory or other consequences on the Company or the Nondisposing Members); provided, further, however, that the Board, in its sole and absolute discretion, may waive compliance with the requirements applicable to Dispositions resulting from a Change of Control in the immediately preceding proviso.

(ii) The Disposing Member and its Assignee, if applicable, shall pay, or reimburse the Company for, all reasonable costs and expenses incurred by the Company in connection with the Disposition and admission, if applicable, including the legal fees incurred in connection with the legal opinions referred to in Sections 4.1(b)(i)(C) and (D), on or before the tenth (10^th) Business Day after the receipt by that Person of the Company’s invoice for the amount due. If payment is not made by the date due, the Person owing that amount shall pay interest on the unpaid amount from the date due until paid at a rate per annum equal to the Default Rate (as determined on the date such amount became due and payable).

(c) Release of Disposing Member. Except as otherwise provided in Sections 3.4 or 4.2(b) or if such Disposition results from a Change in Control, from and after the Disposition of any Membership Units in accordance with this Article IV, the Disposing Member shall be released from all obligations and liabilities arising hereunder on or after the date of the Disposition to the extent of the Membership Units Disposed of; provided, however, that no Disposition hereunder shall release the Disposing Member from any liability or obligation it may have hereunder with respect to liabilities or obligations incurred prior to the date of such Disposition or with respect to Membership Units that it continues to own after the date of such Disposition.

(d) Admission of Assignee as a Member. An Assignee has the right to be admitted to the Company as a Member, with the Membership Units so transferred to such

Assignee, only if the Disposition complies with this Article IV and either the Disposing Member making the Disposition has expressly granted such right to the Assignee or the Board otherwise approves.

(e) Compliance with Sections 103 & 184 of the Atomic Energy Act. Section 103 of the Atomic Energy Act of 1954, as amended (the “AEA”), prohibits the NRC from issuing a license to any entity that is owned, controlled or dominated by a foreign entity or person, and Section 184 of the AEA requires NRC’s prior written consent to any direct or indirect transfer of control of a NRC license. Thus, any change in Membership Units, including (i) a Disposition; (ii) a creation or issuance of additional Membership Units and admission of a new Member pursuant to Section 3.3; or (iii) an exercise by a Member of its right of first offer pursuant to Section 3.8 (collectively, each of (i), (ii) and (iii) a “Change in Membership Units”), (x) could impact the NRC’s review of the pending application for NRC licenses for STP 3 and STP 4 and (y) after issuance of any NRC license for STP 3 or STP 4 to any Subsidiary of the Company, could involve a direct or indirect transfer of control of the Company that would require NRC’s prior written consent. Moreover, if a Change in Membership Units involves any increased ownership by foreign-owned entities, this may require mitigation measures to assure that the foreign-owned Members do not exercise control or domination over the Company as prohibited by the AEA, and such measures may need to take into account any foreign-owned Member’s rights to acquire increased ownership of Membership Units. This Agreement shall be construed in light of these requirements and in a manner that facilitates compliance with these requirements. In addition, to the extent required under the AEA and the NRC’s implementing regulations, orders and license conditions, the Members will negotiate in good faith to agree on amendments to Article V to assure that the Company and the conduct of the Company’s business involving any NRC license continues to remain controlled and dominated by U.S. citizens and/or U.S. controlled entities, as necessary to facilitate any Change in Membership Units.

(f) Notwithstanding anything herein to the contrary, this Section 4.1 (other than Section 4.1(e)) shall not apply to Dispositions of Membership Units as a result of TANE exercising its rights under the Toshiba Credit Agreement and the other Loan Documents.

4.2 Certain Restrictions on Disposition.

(a) Creditworthiness Standards. A Member may not Dispose of all or any portion of its Membership Units to any Person without the approval of the Board (acting by the affirmative vote or written consent of one or more Managers, other than the Manager appointed by the Disposing Member (the “Disposing Manager”), having a majority of the aggregate Voting Percentages in accordance with Section 5.1(c)) unless ^**.

(b) Assignments of Membership Units to Wholly Owned Affiliates. Notwithstanding Section 4.2(a), a Member may assign all or any portion of its Membership Units to a Wholly Owned Affiliate of such Member that is as creditworthy as such Member (as reasonably determined by each Nondisposing Member); provided, however, that the Disposing Member shall not be released from its obligations under this Agreement without the approval of


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

the Board (acting by the affirmative vote or written consent of one or more Managers, other than the Disposing Manager, having a majority of the aggregate Voting Percentages in accordance with Section 5.1(c)).

(c) Nonstrategic Purchasers. A Member may not Dispose of all or any portion of its Membership Units to a Nonstrategic Purchaser unless such Disposition (i) complies with all other relevant restrictions on Dispositions in this Article IV and (ii) does not result in one or more Nonstrategic Purchasers having a Membership Percentage, in the aggregate, equal to or greater than ^**; provided, however, that a Disposition that results in one or more Nonstrategic Purchasers having a Membership Percentage, in the aggregate, equal to or greater than ^** shall be permitted with the prior approval of the Board (acting by the affirmative vote or written consent of one or more Managers, other than the Disposing Manager, having a majority of the aggregate Voting Percentages in accordance with Section 5.1(c)).

(d) Energy Regulatory Matters. A Member may not Dispose of all or any portion of its Membership Units if the Board (acting by the affirmative vote or written consent of one or more Managers, other than the Disposing Manager, having a majority of the aggregate Voting Percentages in accordance with Section 5.1(c)) reasonably determines that such proposed Disposition requires the Company to obtain approval of or make notification to any Governmental Authority (including, for the avoidance of doubt, the DOE) unless the relevant Governmental Authority shall have (i) issued an order approving such proposed Disposition or accepting any such required notification (or otherwise indicating that no further action will be taken with respect to any required notification) or (ii) determined that approval or notification is not required. Notwithstanding any decision by the Company pursuant to the immediately preceding sentence that no approval is required for a given Disposition, such Disposition will not be effective from the date of any determination by any Governmental Authority that the approval of such Governmental Authority is required to effect such Disposition until such approval is obtained. If any Person acquiring Membership Units in connection with a Disposition shall have a Membership Percentage equal to or greater than five percent (5%) following such Disposition, such Person shall deliver to the Company a certificate, in a form and substance prescribed by the Board, certifying that it does not and shall not cause NINA Texas 3 or NINA Texas 4, or their affiliates pursuant to applicable affiliate attribution regulations, to violate Section 39.154 of the Texas Public Utility Regulatory Act and Section 25.401 of the Texas Public Utility Commission Substantive Rules.

(e) Exercise of Cure Rights In Connection with a Failure to Contribute Capital Contributions. Notwithstanding Section 4.2(a), a Member shall Dispose of all of the Membership Units issued to it in exchange for its Capital Contributions pursuant to Section 6.3(a)(i) to the Nonfunding Member that cures its failure to make such Capital Contributions in accordance with Section 6.3(a)(i).

(f) Encumbrances of Membership Units. A Member may Encumber its Membership Units to a Bona Fide Secured Party, and such secured party in respect of such Encumbrance may foreclose such Encumbrance and exercise other legal remedies in respect of


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

such Encumbrance, free of any right of consent of any Member and free of the Preferential Right described in Section 4.3; provided, however, that such secured party and/or any Person that acquires such Membership Units as a consequence of such foreclosure or other exercise of remedies, shall not be entitled to become a Member hereunder with rights under Sections 5.1 and 5.2, unless and until approved by all of the other Members, and any further Disposition of such Membership Units shall thereafter be fully subject to the provisions of this Article IV; provided, further, however, that notwithstanding anything to the contrary in this Agreement, any such secured party and/or Person that acquires such Membership Units as a consequence of foreclosure or other exercise of remedies with respect to an Encumbrance thereon that secures indebtedness under the Toshiba Credit Agreement shall become a Member hereunder with rights under Sections 5.1 and 5.2, without the need for notice or approval of the other Members.

(g) Notwithstanding anything herein to the contrary, this Section 4.2 (other than Sections 4.2(d) and 4.2(f)) shall not apply to Dispositions of Membership Units as a result of TANE exercising its rights under the Toshiba Credit Agreement and the other Loan Documents.

4.3 Preferential Purchase Right.

(a) Preferential Purchase Right. Except for Dispositions of Membership Units permitted in accordance with Section 4.2(b) or as a result of a Change of Control or TANE exercising its rights under the Toshiba Credit Agreement and the other Loan Documents, 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. Each other Member shall have the preferential right (the “Preferential Right”), exercisable by notice (the “Exercise Notice” and each exercising Member, a “Purchasing Member”) to each other Member on or before the ^** Day after the Disposition Notice is given, to acquire, for the same purchase price and on the same terms and conditions as are set forth in the Disposition Notice, such Purchasing Member’s pro-rata portion, based on the Membership Percentages of each Purchasing Member (for purposes of determining such pro-rata portion, including only the Membership Units of the Purchasing Member(s)), of the Membership Units included in such proposed Disposition in accordance with this Section 4.3. If the Purchasing Members fail to exercise their Preferential Right to purchase all of the Membership Units included in such proposed Disposition within such ^** Days, the Disposing Member shall give the Purchasing Members a second notice of the proposed Disposition of the Membership Units which were not subscribed for. Unless on or before the ^** Day 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


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

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 any Membership Units of the Disposing Member. For purposes of the second election under this Section 4.3(a), 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. 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 or before the ^** Day after the date on which the Disposition Notice is given (or if regulatory approvals are required, such as the prior written consent of the NRC or the DOE, on or before the ^** Day after the date on which all such approvals are obtained), unless the Disposing Member and the Purchasing Members agree upon a different place or date. At the closing, (i) the Disposing Member shall execute and deliver to each Purchasing Member (A) 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 (B) any other instruments reasonably requested by such Purchasing Member to give effect to the purchase; and (ii) such Purchasing Member shall deliver to the Disposing Member in immediately available funds its pro-rata portion, based on the Membership Units actually being purchased by each Purchasing Member, of the purchase price for the Membership Units included in such proposed Disposition as set forth in the Disposition Notice.

(c) Failure to Exercise.

Without in any way diminishing the foregoing, it shall be the policy of the Company to endeavor, to the maximum extent possible consistent with the foregoing, to permit the involvement of Officers and other personnel (who may all be Japanese nationals) appointed, seconded, assigned or nominated by the TEPCO Member or any of its Affiliates, in accordance with this Agreement, to a position with the Company or any Subsidiary, without regard to race, nationality or citizenship.

ARTICLE VI

6.2 Subsequent Capital Contributions.

(a) In General. Other than pursuant to Capital Calls (defined below) or as specified in the NINA Contribution Agreement or the TEPCO Investment Agreement, no Member shall be entitled to or obligated to make any contributions to the capital of the Company or to provide any guarantees of the Company’s or any Subsidiary’s obligations.

(b) Capital Calls. The Company will have the right from time to time and at any time by notice to the applicable Members to call for the Members to make contributions to

the capital of the Company in a stated amount (each such call, a “Capital Call”); provided, however, that, if (i) subject to Section 5.1(e)(ii)(J), the Company fails to issue or make a Capital Call as a result of which the Company breaches or is in default under any of the contracts set forth on Schedule 6.2(b)¹ or other contracts approved in accordance with Section 5.1(e)(ii)(K) or fails or is unable to meet its payment or other obligations under any such contract or (ii) the Majority Member or any of its Affiliates announces that it will no longer fund or pursue the development of STP 3 or STP 4 and thereafter the Company ceases making Capital Calls with respect to such Unit, then the Members other than the Majority Member shall have the right to cause the Company to issue or make a Capital Call. Capital Calls shall be made to all Members, and each Member may (but shall not be obligated to), on or before the ^** Day after such Capital Call, pay to the Company in cash such Member’s Membership Percentage of the amount for which the Capital Call is made. For the avoidance of doubt, no new Membership Units shall be issued in connection with a Capital Call if all Members elect to make their respective pro-rata share of contributions in response to a Capital Call pursuant to this Section 6.2(b).

6.3 Failure to Contribute Capital Contributions.

(a) Dilution. If any Member (including the Majority Member) elects not to make a contribution in response to a Capital Call by the ^** Day after such Capital Call (such Member, a “Nonfunding Member”), then the other Members shall have the right:

(i) to make, or to cause their respective Wholly Owned Affiliates that are as creditworthy as the applicable Member (as reasonably determined by each other Member) to make, such contribution pro-rata in accordance with their respective Membership Percentages to the capital of the Company (with the result that the Membership Units of the Members will be proportionately adjusted based on the Capital Contributions); provided, however, that such Nonfunding Member shall have the right to cure any failure to contribute at any point prior to the contribution by the other Members or their respective Wholly Owned Affiliates described in this clause (i) or thereafter by repaying in full the other Members or their respective Wholly Owned Affiliates who have made contributions pursuant to this clause (i) by the earlier of (x) the date of issuance of the next Capital Call and (y) the admission of a new Member to the Company pursuant to Section 6.3(a)(ii), and upon such cure the rights described in this clause (i) shall be of no further effect unless and until a subsequent failure to make a contribution in response to a Capital Call occurs; and

(ii) subject to the restrictions on Dispositions in Section 4.2, on or after the ^** day after such Capital Call, to admit any third-party Person(s) to the Company as a new Member(s) to make a contribution in response to such Capital Call (with the result that the Membership Units of the Members will be proportionately adjusted based on the Capital Contributions) and upon such admission, the Nonfunding Member shall lose any


¹		Note to draft: Schedule to include the Major Contracts set forth on Schedule 5.15(a) of the Investment Agreement and the Toshiba Credit Agreement.

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

right to cure such failure to contribute; provided, however, that any such contribution by such Person shall only be to the extent of the shortfall in the Capital Call resulting from the election by the Nonfunding Member not to make a contribution in response to such Capital Call and in the event such Person elects to make a contribution to the capital of the Company in excess of such shortfall, any Membership Units issued or sold in respect of such excess shall be subject to the provisions of Section 3.8.

(b) Voting Rights. In addition to Section 6.3(a), if a Nonfunding Member does not cure a failure to make a contribution in response to a Capital Call within the time period set forth in Section 6.3(a)(i), then unless and until such time as such Nonfunding Member elects to make or resumes making contributions in response to a subsequent Capital Call (in which case all of the voting rights of the Manager appointed by such Nonfunding Member removed pursuant to this Section 6.3(b) shall be restored, subject to any dilution in Voting Percentages that may have been effected in accordance with this Agreement), the Manager(s) appointed by such Nonfunding Member shall not have the right to direct the Company with respect to (i) all actions and decisions of the Company requiring the affirmative vote or written consent of one (1) or more Managers having a majority of the aggregate Voting Percentages pursuant to Section 5.1(c) and (ii) the matters specified in Sections 5.1(e)(i) and Section 5.1(e)(ii), and the Manager appointed by such Nonfunding Member shall be excluded from any vote or written consent of the Board on such actions, decisions or matters; provided, however, that the Manager appointed by such Nonfunding Member shall not be excluded from voting on the matters specified in Section 5.1(e)(i) for so long as such Nonfunding Member has a Membership Percentage equal to or greater than ^**; and provided, further, that the Manager appointed by such Nonfunding Member shall not be excluded from voting on the matters specified in Section 5.1(e)(ii) for so long as such Nonfunding Member has a Membership Percentage greater than ^**; and provided, further, however, the Manager appointed by the Majority Member shall not be excluded from voting on the matters specified in Section 5.1(e)(ii) for so long as the Membership Percentage of such Majority Member is greater than ^**. For the avoidance of doubt, such Nonfunding Member shall not be excluded from voting on the matters specified in Section 5.1(d)(i) at any time for so long as such Nonfunding Member owns any Membership Units and remains a Member of the Company.

6.4 Return of Contributions. Except as provided in Section 7.2, 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.

proposed Treasury Regulation Section 1.704-1(b)(2)(iv). In connection with the contribution by NINA to the Company of the NINA Initial Contribution, NINA’s Capital Account has been credited with a contribution to the capital of the Company equal to $[•]. In connection with the contribution by the TEPCO Member to the Company of the TEPCO Contribution, the TEPCO Member’s Capital Account has been credited with a contribution to the capital of the Company equal to $[•]. Each Member’s Capital Account shall be increased by the amount of money contributed by that Member to the Company, the fair market value of property contributed by that Member to the Company (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), and allocations to that Member of income and gain (or items thereof) of the Company, 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, 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), allocations to that Member of expenditures of the Company described (or treated as described) in Section 705(a)(2)(B) of the Code, and allocations of Company loss and deduction (or items thereof), including loss and deduction described in Treasury Regulation Section 1.704-1(b)(2)(iv)(g), but excluding items of loss or deduction described in Treasury Regulation Sections 1.704-1(b)(4)(i) or 1.704-1(b)(4)(iii). The Members’ 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) (including in connection with each issuance of Membership Units) 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 Capital Account that reflects all Membership Units 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 Membership Units owned by a Member, the Capital Account of the Disposing Member that is attributable to such Membership Units 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 as determined by the Board, 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 (2) Business Days prior to the date on which estimated income tax payments are required to be made by a U.S. corporate calendar year taxpayer and each due date for the income tax return of a U.S. corporate calendar year taxpayer (without regard to extensions). “Assumed Tax Liability” means an amount calculated with respect to each Member (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) equal to (a) the cumulative amount of federal, state and local 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 (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) as of such Tax Distribution Date, (i) assuming such Member (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) earned solely the items of income, gain, deduction, loss, and/or credit allocated to such Member (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) pursuant to Section 7.3, (ii) after taking proper account of loss carryforwards resulting from losses allocated to the Members (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) by the Company, to the extent not taken into account in prior periods, and (iii) assuming that such Member (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners) is subject to tax at the highest income tax rates applicable to such Member (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners), reduced by (b) all previous distributions made to such Member pursuant to this Section 7.1. If on a Tax Distribution Date there are not sufficient funds on hand to distribute to each Member the full amount of such Member’s (or in the case of a pass-through entity for U.S. federal income tax purposes, such Member’s beneficial owners’) Assumed Tax Liability, such distributions shall be made pro-rata basis among the Members in accordance with their Membership Percentages. 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 Distributions. The Board may from time to time distribute to the Members such amounts as the Board may determine from the funds on hand of the Business, after the payment of all then-due obligations of the Company relating to the Business 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. Such funds shall be distributed pro-rata among the Members in accordance with their Membership Percentages.

7.3 Allocations. For purposes of maintaining Capital Accounts, income, gain, loss and deduction of the Company shall be allocated as follows:

(a) General Allocations. For each taxable year of the Company (including the taxable year in which the dissolution or liquidation of the Company occurs), items of income, gain, loss and expense shall be allocated among the Members during such taxable year in a manner that will, as nearly as possible, cause the Capital Account balance of each Member at the end of such taxable year to equal:

(i) the distribution (if any) that such Member would receive if, on the last day of the taxable year, (x) all the assets were sold for cash equal to their Book Values, taking into account any adjustments thereto for such taxable year, (y) all liabilities were satisfied in cash according to their terms (limited, with respect to each Nonrecourse Liability, to the Book Value of the assets securing such liability), and (z) the

net proceeds thereof (after satisfaction of such liabilities) and any cash on hand were distributed pursuant to Section 7.2, minus

(ii) the sum of (x) the amount, if any, which such Member is obligated to contribute to the capital of the Company, (y) such Member’s share of the Company Minimum Gain determined pursuant to Treasury Regulation Section 1.704-2(g), and (z) such Member’s share of Member Nonrecourse Debt Minimum Gain determined pursuant to Treasury Regulation Section 1.704-2(i)(5).

(b) Special Allocations. Notwithstanding any other provisions of Section 7.3(a), the following special allocations shall be made for each taxable period:

(i) Notwithstanding any other provision of this Section 7.3, if there is a net decrease in Company Minimum Gain during any Company taxable period, each Member shall be allocated items of income and gain 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 7.3(b)(i), the Capital Account of each Member 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 7.3 with respect to such taxable period. This Section 7.3(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 7.3 (other than 7.3(b)(i) above), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Company taxable period, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of income and gain 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 7.3(b)(ii), the balance of each Member’s Adjusted Capital Account 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 7.3(b)(ii), other than Section 7.3(b)(i) with respect to such taxable period. This Section 7.3(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 7.3(b)(i) and Section 7.3(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, items of income and gain 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 created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Section 7.3(b)(i) and Section 7.3(b)(ii).

(iv) If any Member has a deficit balance in its Adjusted Capital Account at the end of any Company taxable period, such Member shall be specially allocated items of gross income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 7.3(b)(iv) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 7.3(b)(iv) have been tentatively made as if this Section 7.3(b)(iv) were not in this Agreement.

(v) Nonrecourse Deductions attributable to the Company for any taxable period shall be allocated to the Members in accordance with their Membership Percentages.

(vi) Member Nonrecourse Deductions relating to the Company for any taxable period shall be allocated one hundred percent (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 7.3(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.

(c) Allocations Following Exercise of Option. If the Option is exercised by the TEPCO Member, then the Company shall comply with the allocation rules described in proposed Treasury Regulation § 1.704-1(b)(2)(iv)(s) and shall make subsequent corrective allocations among the Members of income, gain, loss or deduction, described in proposed Treasury Regulation § 1.704-1(b)(4)(x), solely to the extent necessary to take into account any reallocations of Company capital that were required by proposed Treasury Regulation § 1.704-1(b)(2)(iv)(s) (if any).

7.4 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 determined by the Tax Matters Member.

7.5 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.

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 effect except as modified herein.

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 such Disputing 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 thirtieth (30^th) Day after such notice, any Disputing Member may commence an arbitration under this Article X by notifying each other 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 thirty (30) Days of the appointment of the second Arbitrator, the two (2) party-appointed Arbitrators shall appoint a third Arbitrator who shall chair the arbitration. Where the Dispute at issue involves more than two (2) 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 ^** Days after the appointment of the third Arbitrator or as soon thereafter as practicable) 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 entered and 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 10.4, 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.

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, (iii) has been independently acquired or developed by a Member or its Affiliates without violating any of the obligations of

A Member may disclose Confidential Information to the extent (x) 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 Disposition (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) or (y) a Member is requested pursuant to, or required by, applicable Law or by legal or regulatory process to disclose any Confidential Information (including any request made by the NRC and/or DOE); provided, that such Member will, to the extent legally permissible and reasonably practicable, provide the Company with prompt notice of such request or requirement to enable the Company to seek an appropriate protective order or other remedy, and, at the Company’s sole expense, cooperate with the Company to obtain such protective order and consult with the Company with respect to taking of steps to resist or narrow the scope of such disclosure or legal process; provided, further that if such protective order is not obtained or the Company waives compliance with the provisions hereof, such Member will furnish only that portion of the Confidential Information which, in the opinion of its counsel, is legally required or requested to be disclosed and use its commercially reasonable efforts to ensure that all Confidential Information that is so disclosed will be accorded confidential treatment.

(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 it, 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 its 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 (2^nd) anniversary of the end of the Term.

12.2 Public Announcements. Without the prior written consent of each Member having or deemed as having the Minimum Threshold Percentage, no Member shall make any public statements with respect to the transactions contemplated by this Agreement, except as may be required by applicable Law or regulation or by obligations pursuant to any listing agreement with any national securities exchange. Prior to issuing a press release or other public announcement required pursuant to the preceding sentence, the Members shall, to the extent legally permissible and reasonably practicable, consult with each other and each Member shall have a reasonable opportunity to comment on such press release or announcement.

12.3 Notices. Except as expressly set forth to the contrary in this Agreement, all notices, requests, consents, or other communications 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, mail, electronic mail (with receipt confirmed personally by the recipient (and not by automatic confirmation of receipt)) or facsimile (if followed by courier or mail). A notice, request, consent, or communication given under this Agreement is effective on receipt by the

Member to receive it; provided, that a notice, request, consent, or communication given by electronic mail shall be deemed effective upon being sent in the local jurisdiction from which such electronic mail is being sent, subject to confirmation of receipt by the recipient as set forth in the preceding sentence. All notices, requests, consents, or other communications to be sent to a Member must be sent to or made at the addresses, electronic mail address or fax number set forth on Exhibit A, or such other address, electronic mail address or fax number as that Member may specify by notice to each other Member.

12.5 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.

12.6 Amendment or Restatement. Other than pursuant to Section 3.2, this Agreement or the Certificate may be amended or restated only after approval by the Board and, in the event of an amendment referenced in Section 5.1(d)(i)(B), by Required Member Approval, or in the event of an amendment referenced in Section 5.1(e)(i)(J), by Required Manager Approval.

12.7 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. The Members acknowledge that their respective obligations hereunder are unconditional and absolute without right of set-off or counterclaim.

12.8 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 Members 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.

12.9 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.

12.10 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.

12.11 Parties in Interest; No Third-Party Beneficiaries. This Agreement shall inure to the benefit of, and be binding upon, the parties hereto and their respective successors, legal representatives and permitted assigns. This Agreement is for the sole benefit of the parties hereto and their successors and permitted assigns and nothing herein expressed or implied shall give or be construed to give any Person, other than the parties hereto and such permitted successors and assigns, any legal or equitable rights hereunder.
