Section 2.4 Project Information.

(a) Each Party may identify up to four Project representatives (which shall include its respective Site Representative) for purposes of this Agreement and Amendment (“Project Representatives”). GPC shall also identify a manager or director level employee as the point of contact (“Point of Contact”) with the Participating Parties for the delivery of Project information and responding to requests for Project information provided by any Primary Contractor; provided that, notwithstanding the foregoing, Participating Party’s Project Representatives shall be entitled to contact relevant SNC or GPC team members directly from time-to-time for Project information on discreet topics, subject to each Participating Party’s duty to refrain from unreasonably distracting such team members from their regular duties. Notwithstanding the foregoing, for the purposes of this section, MEAG and the MEAG SPVs shall constitute one Party.

(b) GPC shall make Project information provided by any Primary Contractor available to each Party’s Project Representatives as soon as feasible after receipt of Project information from the Primary Contractor following a request from a Party’s Project Representative, and in no event later than two (2) business days after the request from a Party’s Project Representative to GPC’s Point of Contact, provided that such Project information can be provided in such a timeframe without unreasonably distracting Agents’ personnel from their other duties. GPC shall advise the Participating Parties within one (1) business day of the request if such Project information cannot reasonably be delivered within two (2) business days. In no event shall the delay in delivering requested Project information in SNC or GPC’s possession extend beyond seven (7) business days.

(c) Each Party’s Project Representatives shall be responsible for disseminating Project information within the Party’s respective organizations, consistent with the confidentiality requirements of applicable contracts.

Section 2.5 Meetings. The Parties will receive invitations for their Project Representatives to attend and participate in the regularly scheduled daily Plan of the Day meetings (and scheduled subsequent follow-up meetings) with the functional area managers of each Primary Contractor where progress and schedule of construction activities are discussed with those managers. The Parties’ Project Representatives will also be invited to attend all exit meetings with the NRC in connection with inspection activities. The Parties’ Project Representatives will be provided reasonable advance notice of such meetings. The Parties’ Designated Representatives will continue to be invited to attend Project Management Board meetings and quarterly Construction Review Board meetings. A meeting agenda and a copy of the materials to be discussed at such meetings shall be provided in advance of the meeting.

Section 2.6 Services Agreement Information. (a) Each of SNC and GPC will provide each Party’s Project Representatives with access to regular, periodic, written reports provided to SNC or GPC by WEC, each Primary Contractor and SNC regarding the execution of the work on the Project within one (1) business day after receipt by SNC or GPC, as applicable, and (b) as to any information other than such written reports, SNC or GPC will provide such information as soon as feasible after receipt of such information by SNC or GPC following a request from a Party’s Project Representative, and in no event later than two (2) business days after the request from a Party’s Project Representative to GPC’s Point of Contact for such information, provided that such information can be provided in such a timeframe without unreasonably distracting SNC’s or GPC’s personnel from their other duties. GPC shall advise the Participating Parties within one (1) business day of the request if such information cannot reasonably be delivered within two (2) business days. In no event shall the delay in delivering requested information in SNC or GPC’s possession extend beyond seven (7) business days.

Section 2.7 Claims; Dispute Resolution Processes.

(a) SNC or GPC will notify each Party’s Project Representatives no later than two (2) business days after SNC or GPC becomes aware of an actual third party claim relating to the Project or the completed Additional Units, either pending or threatened in writing, and will provide each Party’s Project Representatives with access to Project information in GPC’s or SNC’s possession concerning such third party claims

and the Parties’ defenses (except for GPC’s and SNC’s privileged attorney work product not within the scope of any applicable joint defense agreement between the Parties) as soon as feasible after request of a Party’s Project Representative.

(b) Each Party will consult in good faith regarding the selection of members of the dispute resolution board established to handle disputes with the Primary Contractor relating to the Project (the “Dispute Resolution Board”) in an effort to achieve unanimous consent as to the identity of the members of the Dispute Resolution Board. The Parties agree that all members of the Dispute Resolution Board will be neutrals and that Parties will not agree to a selection process whereby the Parties and the Primary Contractor each select one member who will then select a third.

(c) GPC will seek input from each other Party in the development of legal and commercial strategy concerning the resolution of Project disputes with the Primary Contractor, including the formulation of any proposed settlement proposal or the consideration and analysis of settlement proposals received from the Primary Contractor. A designated Party representative may attend and observe each negotiating session that is scheduled in advance between the Primary Contractor and GPC or SNC, provided that GPC or SNC representatives will conduct the negotiations on behalf of all of the Parties.

Section 2.8 Electronic Access. Provision of electronic access to Project information shall satisfy the Project information delivery requirements under the Ownership Participation Agreement, as amended hereby, so long as such electronic access provides complete Project information. Where electronic access does not provide complete Project information, such electronic access shall be supplemented.

Section 2.9 Clarification of Site Representative Access Rights. Section 5.5(d) of the existing Ownership Participation Agreement provides that each Party’s Site Representative may attend any meeting described therein other than (i) personnel or conflict-resolving meetings, or (ii) any other meetings that the Agent’s project management or senior management shall reasonably request (emphasis added) such Site Representative not attend. For clarity, the presumption will be that those meetings that do not fall under (i) are open to each Party’s Site Representative and the exception shall be invocation of (ii) to prohibit attendance by a Party’s Site Representative. Upon any invocation of (ii) to prohibit attendance by a Party’s Site Representative, GPC or SNC, as applicable, shall deliver to such Party a written explanation of the reasonable grounds for its prohibition of the Site Representative’s attendance.

Section 2.10 Information and Access Covenant Remedies. Each Party hereby acknowledges, understands and agrees that a breach of the requirements on the part of GPC or SNC to provide information or access to another Party set forth in this Agreement and Amendment, including those obligations in Sections 2.4, 2.5, 2.6, 2.7 and 2.8 hereof, will result in irreparable damage and harm to the other Parties and that the other Parties will not have an adequate remedy at law in the event of any such breach. Therefore, in furtherance, and not in limitation, of the rights of the Parties set forth in Section 8.2(b)(v) of the Ownership Participation Agreement, the Parties hereby agree that, in the event of any such breach of this Agreement and Amendment, the equitable remedies described in Section 8.2(b)(v) of the Ownership

Participation Agreement shall be available to any Party seeking to obtain information or access to which it is entitled hereunder.

Section 2.11 MEAG Representative. Notwithstanding anything to the contrary contained or implied in this Agreement and Amendment (but subject to the last sentence of Section 5.1(c)), MEAG and the MEAG SPVs shall not have separate rights of access, to information, to meeting attendance nor the right to appoint separate individuals to act as their respective designated Party representatives and may instead appoint the same Project Representatives to act as the designated Party representatives of MEAG and all the MEAG SPVs for purposes of the receipt of information, access and meeting attendance to the extent permitted by this Agreement and Amendment.

SECTION 3.0 Amendments to Ownership Participation Agreement and Development Agreement.

Section 3.1 No Unilateral Discontinuance or Deferral Right. No Party shall have a unilateral right to defer or discontinue the Project except as necessary to comply with an order of the GPSC or the NRC. Section 3.8 of the Development Agreement is hereby removed from the Development Agreement in its entirety and each other provision of the Development Agreement or Ownership Participation Agreement that refers to such Section 3.8 or otherwise implies that GPC has a unilateral right to defer or discontinue the Project, including without limitation Section 5.3(b) of the Ownership Participation Agreement, shall be interpreted to give effect to the first sentence of this Section 3.1.

Section 3.2 GPC’s Agency Standard. Section 5.3(a) of the Ownership Participation Agreement is hereby amended to replace the phrase “use its reasonable best efforts to discharge its responsibilities as agent in accordance with Prudent Utility Practice” with the phrase “discharge its responsibilities as agent in accordance with Prudent Utility Practice.”

Section 3.3 Notice of Removal of Agent. Section 5.3(a) of the Ownership Participation Agreement is hereby amended to replace the phrase “upon written notice to the Agent executed by all the other Participating Parties, provided that if an Affiliate of the Agent has an Ownership Interest in either or both of the Additional Units, its execution of such notice shall not be unreasonably withheld” with “upon written notice to the Agent executed by Participating Parties owning more than an aggregate 50% Ownership Interest in the Additional Units.”

SECTION 4.0 SNC Liability, etc.

Section 4.1 SNC Liability. In recognition of SNC’s performance of services as agent At Cost, without a fee, and except in the case of SNC’s Willful Misconduct, the Parties’ sole recourse against SNC or its affiliates (other than GPC) for SNC’s action or inaction in connection with its performance as agent shall be limited to the removal of SNC from its role as agent in accordance with the SNC Letter Agreement, the SNC Operating Agreement, or Section 2.3(d) of this Agreement and Amendment. For clarity, except for extending the existing GPC limitations on agent liability to SNC, the foregoing is meant simply to restate the existing Ownership Participation Agreement on this point and shall not operate to amend the existing Ownership Participation Agreement (including, but not limited to, the existing obligation of GPC

not to make any adverse distinction), the SNC Letter Agreement or the SNC Operating Agreement. For purposes hereof, “Willful Misconduct” shall have the meaning given to it in (and be interpreted in accordance with) the SNC Letter Agreement.

Section 4.2 Clarification. Nothing in this Agreement and Amendment limits SNC’s indemnification and other rights under the SNC Letter Agreement and the SNC Operating Agreement or GPC’s right to charge and collect from the other Parties the charges and costs incurred by GPC in connection with the SNC Letter Agreement and SNC Operating Agreement (including, without limitation, for any such indemnification) in accordance with the Additional Units Agreements (as amended hereby), the Nuclear Managing Board Agreement (as defined in the Ownership Participation Agreement) and related agreements.

Section 4.3 SNC is GPC’s Agent. The Participating Parties acknowledge and agree: (A) that this Agreement and Amendment does not render OPC, MEAG, any of the MEAG SPVs, or Dalton a party to the SNC Letter Agreement or SNC Operating Agreement; (B) that this Agreement and Amendment does not modify the rights of OPC, MEAG, any of the MEAG SPVs, or Dalton as third party beneficiaries of the SNC Letter Agreement and the SNC Operating Agreement as set forth in those agreements; and (C) SNC is not agent for OPC, MEAG, any of the MEAG SPVs or Dalton, except as and to the extent provided in Section 11.13 of the SNC Operating Agreement or Paragraph 7 of the SNC Letter Agreement.

SECTION 5.0 Miscellaneous.

Section 5.1 Construction; Relationship to Additional Units Agreements.

(a) The rights and obligations of the Parties established in Section 2 of this Agreement and Amendment are in all respects in addition to, and shall in no way limit (but shall not result in duplication of), the existing rights of the Parties under the Additional Units Agreements, including without limitation (i) the Parties’ existing rights under the Additional Units Agreements to approve, vote on or consent to certain decisions or actions relating to the Project or the completed Additional Units and (ii) the Parties’ existing rights under the Additional Units Agreements to receive and audit certain information relating to the Project or the completed Additional Units, maintain Site Representatives, and attend certain meetings, including without limitation those rights under Sections 5.2(d), 5.5, 5.6, 5.7, 5.8, 6.2, 6.4, 6.6, 7.2, 7.8 and 8.2(b)(v) of the Ownership Participation Agreement and Section 3.9 of the Development Agreement, as applicable.

(b) Except as expressly amended hereby, the Development Agreement and the Ownership Participation Agreement and all other provisions thereof remain and shall continue to be in full force and effect and are hereby ratified, subject in all respects to Sections 5.1(a) and (c).

(c) The Additional Units Agreements shall be interpreted, applied and enforced so as to give full effect to this Agreement and Amendment. For the avoidance of doubt, notwithstanding anything to the contrary contained or implied in this Agreement and Amendment, this Agreement and Amendment is not intended to and shall not be

directly or indirectly interpreted or applied so as to directly or indirectly modify or supplement any of the document provisions identified in Exhibit B hereto.

Section 5.2 Counterparts. This Agreement and Amendment may be executed simultaneously in two or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. Further, the signatures of the duly authorized representatives of each Party hereto need not be contemporaneous and shall be deemed effective if exchanged by electronic transfer between the Parties hereto or their respective designees, including transmittal by facsimile or electronic mail.

Section 5.3 Joint Drafting. No Party shall assert or claim a presumption disfavoring the other by virtue of the fact that this Agreement and Amendment was drafted primarily by legal counsel for the other, and this Agreement and Amendment shall be construed as if drafted jointly by the Parties and no presumption or burden of proof will arise favoring or disfavoring a Party by virtue of the authorship of any of the provisions of this Agreement and Amendment.

Section 5.4 Governing Law. The validity, interpretation, and performance of this Agreement and Amendment and each of its provisions shall be governed by the internal Laws of the State of Georgia.

Section 5.5 Severability. If any provision of this Agreement and Amendment is declared by any regulator or court of competent jurisdiction to be invalid or unenforceable, the balance of this Agreement and Amendment shall remain in effect, and this Agreement and Amendment shall be interpreted so as to give full effect to its effective terms and still be valid and enforceable.

Section 5.6 Headings. Headings appearing herein are used solely for convenience and are not intended to affect the interpretation of any provision of this Agreement and Amendment.

Section 5.7 Entire Agreement.

SNC hereby acknowledges and agrees to all of its rights and obligations, and modifications to its existing rights and obligations, set forth in the immediately above specifically enumerated sections of this Agreement and Amendment. SNC also hereby agrees to join in the execution of any consent, assignment, agreement or other instrument or document reasonably requested by the DOE in connection with the DOE-guaranteed federal
