ARTICLE II
OWNERS

Section 2.1 Ownership Interests.

(a) As of the Effective Date, subject to adjustments as provided herein, the Owners own all rights relating to STP 3, STP 4 and the STP 3 & 4 Common Facilities, in undivided interests as

tenants in common as follows (such interests being, with respect to each of STP 3 and STP 4, an Owner’s “Unit Ownership Interest”):


STP 3 and ▇▇▇ ▇ & ▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇

▇▇▇ ▇▇▇▇▇▇▇	7.625	%
NINA 3	92.375	%

STP 4

San Antonio	7.625	%
NINA 4	92.375	%

(b) The Parties recognize and acknowledge that at any time prior to the Funding Recommencement Date for each Unit, NINA 3 and/or NINA 4 may choose to abandon the development of the Project without liability to any Owner, other than pursuant to any written agreements among the Parties; provided, however, that the NINA Parties hereby agree that they will not pursue a “downsized Project” (i.e., Unit 3 alone). In the case of Abandonment, in no event will San Antonio’s Unit Ownership Interest ever fall below 7.625%.

(i) If STP 3 or the Project is Abandoned at any time prior to conditional approval from the DOE with respect to the loan guaranty term sheet, then, at San Antonio’s option in its sole and absolute discretion exercised upon delivery of written notice to NINA within 90 days after the date San Antonio becomes aware of such Abandonment, the Owner’s Unit Ownership Interest will automatically revert to 50% without any further action of the Parties.

(ii) If STP 3 or the Project is Abandoned at any time after conditional approval from the DOE with respect to the loan guaranty term sheet, but prior to FNTP, then, at San Antonio’s option in its sole and absolute discretion exercised upon delivery of written notice (the “Repurchase Notice”) to NINA within 90 days after the date San Antonio becomes aware of such Abandonment, (A) each Owner’s respective Unit Ownership Interest will automatically revert to the proportion that the Total Project Costs actually paid by such Owner prior to the Abandonment date bears to the Total Project Costs paid by all Owners through such date, without any further action of the Parties, and (B) San Antonio shall have the right to increase its Unit Ownership Interest to any percentage between the percentage in clause (A) and 50% upon payment to the NINA Parties of an amount equal to the difference between (1)(x) Total Project Costs actually paid by all Parties prior to the Abandonment date, times (y) the percentage that San Antonio wants to own, minus (2) the Total Project Costs actually paid by San Antonio prior to such date. The closing of the repurchase described in clause (B) shall occur no later than 12 months after the date of receipt by the NINA Parties of the Repurchase Notice. For purposes of the formulas contained in paragraph (ii), the Owners hereby agree that (I) they shall count only the out-of-pocket Total Project Costs relating to the development, licensing, design, construction and starting-up of the Project, and not any Total Project Costs relating to the financing of the Project or relating to an Owner’s internal matters, such as financing costs, interest, commitment fees, investment banking fees, over-head costs or personnel costs, (II) San Antonio, on the one hand, and the NINA Parties, on the other hand, have paid an equal amount of Total Project Costs through the date of this Agreement, and (III) any payments made to San Antonio by NRG (by and for the benefit of the NINA Parties) under Sections 3.1.1 and 3.1.2 of the Project Agreement (i.e., the Initial Cash Payment and Remaining Cash Payment thereunder), as and when paid, shall increase or decrease, as applicable, an Owner’s share of the Total Project Costs. For the

avoidance of doubt, with respect to the “City Initiative Contribution” under the Project Agreement, no portion of such contribution shall be included in the calculation of Total Project Costs under this Section 2.1(b)(ii). An example of the foregoing formula is set forth on Schedule 2.1(b)(ii).

(iii) If STP 3 or the Project is Abandoned at any time after FNTP and San Antonio has not acquired any additional Ownership Interest or exercised its rights pursuant to this Section 2.1, then the Unit Ownership Interests shall remain as provided in Section 2.1(a).

Promptly after San Antonio’s exercise of its right to increase its Unit Ownership Interest, NINA, NINA 3 and NINA 4, as applicable, shall execute, acknowledge and deliver all documents and shall take all other actions reasonably necessary to convey the applicable Unit Ownership Interest to San Antonio, free and clear of all Liens (other than those to which the conveyances under Section 2.1.2 of the Project Agreement are subject, those arising under applicable Law or the Participation Agreement, those which are customary title encumbrances of a non-lien nature that arise during the ordinary course of development of a nuclear facility and that are granted pursuant to the NINA Parties’ authority under Section 3.1 hereof or granted by San Antonio, or those of the type described in clause (y) of Section 3.1(b)(vi) hereof) including such documentation reasonably satisfactory to San Antonio, its creditors and lenders (including the DOE, if applicable), to effect the transfer of the relevant portion of the NINA Parties’ undivided tenant-in-common percentage interest in: (a) the land on which the Project (comprising only STP 3 and STP 4) is located and in all improvements located thereon, and (b) the Common Station Facilities. San Antonio, on behalf of itself and its creditors and lenders, agrees that the deeds and conveyance instruments that shall be used by the Parties pursuant to Section 2.1.2 of the Project Agreement are acceptable forms to effect the conveyances contemplated by this Section 2.1(b).

Following Abandonment, the NINA Parties and San Antonio shall be responsible, in proportion to their Abandonment Restoration Costs Share, for all costs of Abandonment, including restoring the Site (to the extent not occupied by the Existing STP Units) to the condition (including completing all landscaping and other restoration work to the extent) set forth in the ETS and in accordance with all Applicable Laws and Applicable Permits. “Abandonment Restoration Costs Share” shall mean (a) as to the NINA Parties, 100% minus the amount of percentage increase in Unit Ownership Interest acquired by San Antonio pursuant to San Antonio’s exercise of its right pursuant to Section 2.1(b)(ii)(B) (the “San Antonio Restoration Costs Share”), and (b) as to San Antonio, the San Antonio Restoration Costs Share. San Antonio shall reimburse the NINA Parties for the San Antonio Restoration Costs Share of any costs of Abandonment paid by the NINA Parties between the Abandonment date and the date when San Antonio exercises its right pursuant to Section 2.1(b)(ii)(B).

Section 2.2 Additional Owners. Any Person to which a Unit Ownership Interest in STP 3 and/or STP 4 is transferred in accordance with this Agreement or the Participation Agreement must assume the obligations of the transferring Owner and become an Owner under this Agreement and must execute an assignment and assumption agreement as evidence thereof.

Section 2.3 Term. The term of this Agreement shall commence as of the Effective Date and shall remain in force and effect until the expiration of the Participation Agreement.

Section 2.4 Related Agreements.

(a) The terms of the Participation Agreement shall govern the rights and obligations of the Owners except to the extent of the agreements among the Owners set out in this Agreement relating to STP 3 and/or STP 4, which agreements shall, as among the Owners, control in the event of a conflict between this Agreement and the Participation Agreement. For the avoidance of doubt, any failure to

make reference in this Agreement to any specific provision of the Participation Agreement shall not be interpreted to mean that such provision is inapplicable to the Owners.

(b) The Owners acknowledge and agree that OPCO shall, pursuant to the terms of the Operating Agreement, license, operate, construct, maintain and decommission STP 3 and STP 4. Upon assignment of its rights, obligations and liabilities under the Agency Agreement from San Antonio to NINA 3 and NINA 4, the relationship between OPCO and the Owners regarding oversight of the Project construction, including during the development, licensing and construction phases of STP 3 and/or STP 4, as applicable, shall be governed by this Agreement.

(c) As to the EPC Contract and other Project documents entered into by OPCO under the Agency Agreement or by the Owners directly (whether before or after the date hereof, including documents entered into after the date hereof by the NINA Parties), even though all or a portion of the beneficial interest in such agreements have been assigned to the NINA Parties, each Owner shall continue to own its Unit Ownership Interest share of the following rights: (i) any work product, intellectual property rights or tangible property as it relates to the Project to which the owner under the EPC Contract obtains title pursuant to the terms thereof and (ii) cash proceeds paid to the owners under the EPC Contract by or on behalf of TANE pursuant to the EPC Contract (including liquidated damages, warranty or casualty proceeds) to the extent not used to repair or reconstruct the Project (such cash proceeds, a “Distribution”).

(d) In furtherance of the foregoing, the NINA Parties agree as follows:

(i) If the NINA Parties receive a Distribution, the NINA Parties shall (A) accept and hold San Antonio’s Unit Ownership Interest share of such Distribution for the account and sole benefit of San Antonio, (B) have no equitable or beneficial interest in San Antonio’s Unit Ownership Interest share of such Distribution, and (C) deliver San Antonio’s Unit Ownership Interest share of such Distribution (free of any withholding, setoff, recoupment, or deduction of any kind) promptly to San Antonio. In addition, the NINA Parties shall do all acts and shall execute and deliver such further written instruments as may be reasonably required to vest in San Antonio the rights described in Section 2.4(c)(i) above.

(ii) The NINA Parties (A) shall maintain records of all payments made to the NINA Parties with respect to the EPC Contract or such other Project documents, and (B) shall cause OPCO, in the ordinary course of its business and consistent with its past practices, to maintain records relating to the work product, intellectual property rights and tangible property as it relates to the Project to which the owner under the EPC Contract obtains title pursuant to the terms thereof. Such records shall be available for inspection by San Antonio from time to time upon reasonable prior notice to the NINA Parties during regular business hours.

ARTICLE III
VOTING

Section 3.1 Decisions Relating to STP 3 and STP 4.

(a) As to decisions of the Owners Committee affecting only one or more of the Units, then each of NINA 3 and NINA 4, with respect to the Project and from and after the San ▇▇▇▇▇▇▇ ▇▇▇▇▇ Funding Date (as defined in the Project Agreement), shall have full discretion and control for the operation, maintenance, planning, development, construction (including being the party to the EPC Contract), construction and development scheduling, financing and other aspects of management of such Unit, including decisions with respect to (i) management of the EPC Contract and development or

cancellation of the Project; (ii) day-to-day operations, including relationship with OPCO and direction as to interface between OPCO, as licensee, and the NRC; (iii) government relations, including interface with the NRC; (iv) insurance as to the Project (as long as such insurance (A) meets the requirements in the Participation Agreement and the EPC Contract, and (B) names San Antonio as an additional insured), but nothing shall prevent San Antonio from maintaining at its own cost, additional insurance it deems necessary; (v) decommissioning and the timing thereof; (vi) budgets; (vii) maintenance, repairs and casualty restoration; (viii) Project litigation (unless San Antonio is a party to such suit or there exists an actual or potential conflict of interest between the NINA Parties or their counsel and San Antonio, in which case San Antonio may participate in such litigation at its own cost and expense); provided, however, that in making its decisions relating to Project litigation, NINA 3 and NINA 4 may not agree, without San Antonio’s prior written consent, to any settlement or compromise of such litigation (A) that involves any non-ministerial non-monetary obligations to be performed by San Antonio, or (B) that involves monetary obligations on San Antonio that are in excess of its proportionate Unit Ownership Interest; (ix) NRC license extensions; (x) the right to sell, lease, make a sale-leaseback, exchange, convey or dispose of assets of the Project the ownership of which are not necessary for the operation of the Project; (xi) the right to license intellectual property rights of the type described in Section 2.4(c)(i), but each Owner shall have the right to its Unit Ownership Interest in the net proceeds thereof; and (xii) upratings and improvements, in each case, whether such decision is made prior to or after the Funding Recommencement Date for each Unit.

(iii) Each Party, on behalf of itself and its Affiliates, successors and assigns, will use commercially reasonable efforts (which shall not include any requirement to threaten or initiate litigation) to look to available insurance for the Project, if any, to cover the matters that are the subject of this indemnity and, to the extent such insurance coverage is obtained, each Party hereby waives on behalf of its insurers all right to subrogation. Notwithstanding the previous sentence, the NINA Parties shall perform their obligations under Section 3.1(d)(i) (A) until the applicable insurance carrier for the Project affirmatively agrees to assume the defense (at its costs) of the matters that are the subject of this indemnity, and (B) to the extent that such insurance does not fully cover the matters that are the subject of this indemnity. If San Antonio (or its Affiliates and their successors and assigns) receives any insurance proceeds with respect to a matter for which such Person has previously been indemnified hereunder, then such Person shall promptly refund to the NINA Parties a portion of such proceeds (net of direct collection expenses and less any adjustments to past, present and future insurance premiums) equal to the amount paid by the NINA Parties hereunder.

(iv) Except as provided in this Section 3.1(d), this Section 3.1 is not intended to grant an Owner any additional rights to make any direct claims against another Owner, or to increase the liabilities of an Owner towards another Owner, beyond the limitations set forth in the Participation Agreement. The provisions of Section 20.3 of the Participation Agreement shall apply to this Agreement

(e) Nothing in this Agreement will modify or limit San Antonio’s rights with respect to decisions involving the Existing STP Units or involving both the Units and the Existing STP Units or involving the Common Station Facilities which are for the common use of the Units and the Existing STP Units.

Section 3.2 San Antonio Cooperation. San Antonio shall cooperate with and assist the NINA Parties promptly, as and when reasonably requested by the NINA Parties and at the NINA Parties’ expense, to the extent necessary for the NINA Parties to perform their duties, responsibilities and obligations under this Agreement, the EPC Contract and other agreements related to the financing, construction and operation of the Project, including:

(a) executing and delivering documents, certificates or instruments requested by the NINA Parties that are necessary in connection with the financing of the Project and the NINA Parties’ performance of such duties, responsibilities and obligations; and

(b) supporting the NINA Parties’ efforts to receive a United States Department of Energy loan guaranty for the Project (including by providing clarity to the DOE on San Antonio’s ownership position in the Project); provided, that unless requested by the NINA Parties or the DOE, or unless required in order to comply with applicable Law, San Antonio shall not attend any meetings with the DOE or request additional data from the DOE regarding such loan guaranty.

San Antonio will be deemed to comply with this Section 3.2 if it acts in good faith in response to a request from the NINA Parties that is consistent with the terms on this Section 3.2. The NINA Parties’ sole remedy for a breach of this Section 3.2 by San Antonio will be an action for specific performance, and in no event will San Antonio be liable for monetary damages to the NINA Parties or to any other Person for a breach or alleged breach of this Section 3.2.

Section 3.3 Access to Information. With respect to STP 3, STP 4 and/or the ▇▇▇ ▇ & ▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇ shall have such rights of access and audit as are described in the Participation Agreement and Operating Agreement. If requested by San Antonio, the NINA Parties shall provide reasonable assistance to San Antonio in gaining access to all of OPCO’s books and records and to all of its material correspondence with Government Authorities relating to STP 3, STP 4 and/or the STP 3 & 4 Common Facilities. In addition, the NINA Parties will provide San Antonio with reasonable access to, and the right to inspect and audit, the books and records of the Owners Committee. The foregoing rights in this Section 3.3 represent all of San Antonio’s rights to access information or participate in meetings relating to the development and construction of the Project.

Section 3.4 Allocation of Costs and Obligations to Pay Costs.

(a) From and after February 1, 2010 and except as set forth in Section 3.4(b) below, NINA 3 and NINA 4 (and their permitted transferees) will be solely responsible for and shall pay the Project Costs and Total Project Costs (including all liabilities and obligations of the Owners under the EPC Contract), and San Antonio will have no liability or obligation for any Total Project Costs; provided, however, that San Antonio agrees to pay when due, in the ordinary course of business consistent with OPCO’s customary historical practices, its 50% of the costs set forth on Schedule 3.4(a) attached hereto relating to the portion of services rendered and materials delivered on or prior to January 31, 2010. For the avoidance of doubt, (i) San Antonio shall not be responsible for any Total Project Costs other than those expressly set forth on Schedule 3.4(a), regardless of whether such amounts were approved by San Antonio on or before January 31, 2010, (ii) the costs set forth on Schedule 3.4(a) are estimated amounts, and San Antonio shall not be obligated to pay such costs until the actual amounts are determined and invoiced by OPCO, and (iii) for the line item on Schedule 3.4(a) titled “TANE Long Lead Material”, San Antonio shall pay 50% of $[*], or $ [*], with payments up to these amounts made when due after invoices are received. If San Antonio has paid or in the future pays any amounts relating to services rendered or to be rendered or materials delivered or to be delivered after January 31, 2010 (as reasonably determined by OPCO), then such payments shall reduce the amounts payable by San Antonio under this Section 3.4(a). San Antonio shall have the right to review the invoices, work papers, worksheets and other documents relating to the costs on Schedule 3.4(a) in order to independently verify the estimated and actual amounts to be paid by San Antonio under this Section 3.4(a). If San Antonio disputes the determination by OPCO, then San Antonio will notify NINA and OPCO. If San Antonio, NINA and OPCO are unable to resolve the dispute within 30 days after San Antonio’s notice, then San Antonio and NINA shall submit the dispute for determination to a nationally recognized accounting firm mutually acceptable to San Antonio and NINA (which firm may not be a firm that has been engaged by the Parties during the prior two years). The determination of the accounting firm shall be final and binding on the Parties. NINA and San Antonio shall each pay half of the fees and costs of such accounting firm’s review and determination.

(b) From and after the Funding Recommencement Date of each Unit, each Owner shall be obligated to fund its Unit Ownership Interest share of the Project Costs incurred after such date with respect to such Unit as provided under the Participation Agreement and the Operating Agreement (and any successor agreements thereto); provided, however, that NINA 3 and NINA 4 (and their permitted transferees) will continue to be solely responsible for and shall pay all liabilities and obligations under the EPC Contract and all other Project Costs relating to development and construction of the Project (whether incurred before or after the Funding Recommencement Date) that are necessary to achieve Final Completion of the Project.

Section 3.5 Power Production Prior to Final Completion Date.

(a) Prior to the Funding Recommencement Date, the NINA Parties shall designate a Qualified Scheduling Entity pursuant to the ERCOT regulations who will be responsible for scheduling

power for such Unit. Any revenues generated by a Unit during such period shall be paid to and for the benefit of the NINA Parties in proportion to their ownership of such Unit.

(b) Following the Funding Recommencement Date, each Owner with a Unit Ownership Interest in such Unit shall designate a Qualified Scheduling Entity pursuant to the ERCOT regulations, who will be responsible for scheduling power allocable to such Owner until the Unit reaches its Final Completion Date.

(c) From and after the Final Completion Date, each Owner of such Unit have the obligation to take its Generation Entitlement Share (as defined in the Participation Agreement) of power and energy produced from such Unit during such period, which shall be equal to its Unit Ownership Interest in such Unit.

Section 3.6 Cooperation Among Owners. Upon the reasonable request of any Party, and at the requesting Party’s expense, the other Parties shall furnish such information and documentation regarding such Party as reasonably requested by the requesting Party and necessary for the requesting Party’s performance of its duties, responsibilities and obligations under this Agreement, the EPC Contract and other agreements related to the financing, construction and operation of the Project.

Section 3.7 Indemnification. The Owners’ rights and obligations with respect to indemnification shall be as provided in the Participation Agreement and nothing set forth herein shall be construed as a waiver of any such rights of the parties under the Participation Agreement.

ARTICLE IV
TRANSFERS

Section 4.1 Transfers.

(a) Restriction. NINA, NINA 3 and NINA 4 will not, and will not permit its Ultimate Parent or a subsidiary of its Ultimate Parent to, sell, assign, transfer or otherwise dispose of, except pursuant to (b) below, an equity interest in (or issue equity interests in) any direct or indirect subsidiary of the Ultimate Parent owning directly or indirectly a Unit Ownership Interest in STP 3 and/or 4, where all or substantially all of such subsidiary’s assets are directly (or indirectly through one or more subsidiaries) the Unit Ownership Interest in STP 3 and/or 4.

“Ultimate Parent” means, as applicable with respect to NINA 3 and NINA 4, NRG as well as any Person that is a transferee or purchaser of an equity interest in a transaction after the date hereof as to which the restriction in (a) above would apply, but for the application of (b)(i) or (b)(iii) below. For the avoidance of doubt, as to the Person that is the transferee or purchaser in the preceding sentence, such Person shall be an Ultimate Parent, but not any parent entity of such Person.

(b) Permitted Transfers. The foregoing restriction shall not apply to any of the following:

(i) a sale, disposition or issuance to an Affiliate;

(ii) a transfer or disposition as collateral security or pursuant to hypothecation, pledge, or mortgage or similar lien granted in good faith pursuant to a bona fide financing transaction, or with respect to the foreclosure, transfer or disposition thereof by a collateral agent;

(iii) a bona fide sale, disposition or issuance made prior to the Funding Recommencement Date of both Units 3 and 4; or

(iv) an issuance of equity in an entity (A) to the existing holders of equity in such entity pro rata in accordance with their ownership interests, (B) in connection with an initial or subsequent public offering, or (C) in connection with a private placement or similar transaction where the existing holders of equity in such entity are diluted pro-rata as to their ownership in such entity and where such issuance is not part of an arrangement that specifically includes distributions to the existing equity holders of the issuing entity or any purchases or redemptions of equity interests of the existing equity holders in the issuing entity and therefore would have the effect of transferring an existing equity holder’s direct or indirect interest in STP 3 and/or 4 to the new equity holder(s) beyond such pro-rata dilution arising from such issuance.

(c) The NINA Parties agree that if within ten years after the Funding Recommencement Date of both Units 3 and 4 they become aware that a holder of an equity interest in any of the NINA Parties desires to sell some or all of that interest, the NINA Parties will use commercially reasonable efforts to request such holder of an equity interest to enter in discussions with San Antonio about a possible sale of a portion of that interest to San Antonio.

SCHEDULE 2.1(b)(ii)

Abandonment Calculation Example

Data Points:

	(a)		Abandonment occurs after payment of Initial Cash Payment and Remaining Cash Payment: $80 million total

	(b)		Total Project Costs expended by NINA Parties and San Antonio through date of Agreement: $300 million each ($600 million total)

	(c)		Out-of-pocket Total Project Costs (including Initial Cash Payment and Remaining Cash Payment) expended by NINA Parties at time of Abandonment: $580 million

	(d)		Costs of Abandonment expended by NINA Parties between Abandonment date and closing of repurchase by San Antonio: $200 million

Calculation:

Automatic reversion pursuant to Section 2.1(b)(ii)(A):

NINA Parties: 72.5% Unit Ownership Interest
(i.e., $580 million / $800 million)

San Antonio: 27.5% Unit Ownership Interest
(i.e., $220 million / $800 million)


	(b)		San Antonio Unit Ownership Interest increase pursuant to Section 2.1(b)(ii)(B):

San Antonio decides to repurchase up to 50% Unit Ownership Interest (i.e., 22.5% San Antonio Restoration Costs Share).

Payment for Unit Ownership Interest:

$180 million (i.e., ($800 million * 50%) — $220 million)

Reimbursement payment for Abandonment costs:

$45 million (i.e., 22.5% * $200 million)
