1000 Independence Ave. S.W.

Washington, D.C. 20585

Attention: Mr. John Sneed, Executive Director Loan Programs Office, U.S. Department of Energy

Re: Loan Guarantee Agreement dated as of February 20, 2014, as amended (the “LGA”), between Oglethorpe Power Corporation (An Electric Membership Corporation), as Borrower (the “Borrower”), and U.S. Department of Energy (“DOE”), relating to Vogtle Electric Generating Plant, Units 3 and 4 (“Vogtle 3 and 4” or “Project”)

Ladies and Gentlemen:

This letter is being delivered to DOE in connection with the Borrower’s Advance Notice, dated on or about the date hereof, for a $585,000,000 Advance on March 15, 2019, under its Future Advance Promissory Note No. 2 (the “March 2019 Advance”). This letter sets forth certain requests by the Borrower for amendments to the LGA and waivers of terms and conditions under the LGA in connection with the March 2019 Advance. Capitalized terms used and not otherwise defined in this letter shall have their respective meanings specified in the LGA, as modified by Annex A hereto. Unless otherwise indicated, all section, article and exhibit references are references to the LGA.

Background

Pursuant to Sections 2.2.3(a) (Mechanics for Requesting Advances; Advance Notice), 4.2 (Conditions Precedent to Each Advance) and 10.23 (Interim Agreement Prior to Completion Assessment and Replacement EPC Arrangements), the March 2019 Advance is not permitted under the LGA until certain conditions set forth therein are satisfied or waived in writing. Among other conditions, (i) Section 2.2.3(a) (Mechanics for Requesting Advances; Advance Notice) requires the Borrower to deliver an appropriately completed Advance Notice to DOE not less than twenty (20) Business Days prior to any Requested Advance Date, in the case of an Advance in an amount equal to or greater than $500,000,000 and less than $2,000,000,000, (ii) Section 4.2.2 (Invoices and Lien Waivers) requires the Borrower to deliver to DOE copies of (a) lien waivers and releases with respect to all work reflected in each invoice of the EPC Contractor that are the subject of an Advance and (b) certain invoices, and (iii) Section 10.23 (Interim Agreement Prior to Completion Assessment and Replacement EPC Arrangements) prohibits Advances under Article

4 (Conditions Precedent to Advances) until the conditions set forth in Section 10.23 (among other things, requiring an amendment to the LGA to reflect the Replacement EPC Arrangements) are satisfied.

Advance Notice Period

DOE has indicated to the Borrower that it is willing to accommodate the Borrower’s proposed schedule for the March 2019 Advance by waiving the requirement that the Advance Notice for the March 2019 Advance be delivered to DOE twenty (20) Business Days prior to the Requested Advance Date for the March 2019 Advance and requiring instead that the Advance Notice for the March 2019 Advance be delivered to DOE six (6) Business Days prior to the Requested Advance Date for the March 2019 Advance (i.e., by March 7, 2019).

Lien Waivers and Invoices

As of the date hereof, the EPC Contractor had not delivered and is not expected to deliver lien waivers and releases associated with the Interim Assessment Agreement. The Borrower will certify, however, in the Borrower Advance Date Certificate for the March 2019 Advance that (i) the Borrower has paid all amounts required under the Interim Assessment Agreement, (ii) GPC, on behalf of itself and as Owners’ Agent, has filed a claim in the Chapter 11 bankruptcy proceeding of Westinghouse and WECTEC (the “Debtors”) seeking reimbursement of, among other things, approximately $56.4 million previously paid under the Interim Assessment Agreement (the “Disputed Payment Amount”) and (iii) while Wind Down Co, the entity responsible for administering the Debtors’ obligations under the confirmed plan of reorganization has asserted claims that could result in the Debtors retaining less than all of the funds in the Disputed Payment Amount, to the Knowledge of the Borrower, neither Wind Down Co nor any other party has asserted that the Borrower is required to make further payments under the Interim Assessment Agreement beyond the payments previously made by the Borrower.

In addition, in light of the significant changes to the contractual arrangements relating to the Project following the bankruptcy of the EPC Contractor, the Borrower, DOE and the Lender’s Engineer have discussed and developed an updated set of invoice delivery requirements that more appropriately reflect the current Project structure.

Replacement EPC Arrangements

DOE has indicated to the Borrower that it is willing to waive the Borrower’s compliance with Section 10.23 (Interim Agreement Prior to Completion Assessment and Replacement EPC Arrangements) solely for purposes of the March 2019 Advance, provided that DOE has received, among other items, (a)(i) copies of the most recent updates of each of the Completion Assessment, the Project Milestone Schedule, the Summary Project Milestone Schedule — Regulatory Based, the Summary Project Milestone Schedule — Working Plan, the Construction Budget and the Base Case Projections, (ii) access to such information as DOE shall have reasonably requested in connection with completing its review of the documents listed in the preceding clause (i), (iii) copies of each requested invoice, lien waiver and release with respect to each of the EPC Contractor (under the EPC Contract and the Interim Assessment Agreement), the Service Provider and the CCA

Contractor through June 30, 2018 (other than lien waivers and releases with respect to work performed by the EPC Contractor under the Interim Assessment Agreement), (iv) copies of other specified invoices and (v) copies of certain Additional Project Documents and Loan Documents entered into in connection with the Replacement EPC Arrangements, in each case accompanied by a certification of the Borrower that such copies are true, correct and complete; (b) from each of the CCA Contractor and the CCA Guarantor, its most recent audited and unaudited Financial Statements; and (c) certain legal opinions from counsel to the Borrower, in-house counsel to Westinghouse Electric Company LLC, in-house counsel to the CCA Contractor and the CCA Guarantor and special counsel to the Owners’ Agent, in each case relating to certain Additional Project Documents and Loan Documents entered into in connection with the Replacement EPC Arrangements.

To induce DOE’s consent and waiver as requested herein, the Borrower will certify to DOE that (i) to the Borrower’s Knowledge, the Operator is not in breach of its obligations under the Letter Agreement for Construction Services, except for any such breach that could not reasonably be expected to have a material adverse effect on the completion or operation of the Project; (ii) to the Borrower’s Knowledge, the CCA Contractor is not in breach of its obligations under the Construction Completion Agreement, except for any such breach that could not reasonably be expected to have a material adverse effect on the completion or operation of the Project; (iii) to the Borrower’s Knowledge, the Service Provider is not in breach of its obligations under the Services Agreement, the Westinghouse Direct Agreement, the IP License, and the Triggering Event IP License, except for any such breach that could not reasonably be expected to have a material adverse effect on the completion or operation of the Project; and (iv) as of the Advance Notice Date and the Advance Date for the March 2019 Advance no PAE has occurred for which at least 90% of the Ownership Interests in the Project have not been voted in favor of continuing the construction, completion, testing, startup and pre-operational turnover of the Project.

Requested Amendments

The LGA provides, pursuant to Section 10.5 (Amendment or Waiver), that any amendment or waiver under the LGA must be in writing and signed by the Borrower and DOE. To allow the Borrower to proceed with the March 2019 Advance, the Borrower hereby requests DOE agree to the following amendments:

(a) modifying Exhibit A (Definitions) in accordance with Annex A;

(c) adding the phrase “or otherwise acceptable to DOE” immediately following “Exhibit C-2” in Section 4.2.6(a) (Advance Certificates);

(d) replacing paragraph (i) (EPC Contractor) of Section 5.26 (U.S. Government Requirements) in its entirety with the representations attached hereto as Annex B;

(g) replacing Sections 7.7(c) (Limitations on Certain Types of Contracts) in its entirety with the restrictions set forth in Annex D;

(h) replacing paragraph 14 (Forward-Looking Statements) in Exhibit B (Rules of Interpretation) with the provisions attached hereto as Annex E; and

(i) replacing Exhibit M (Form of Project Cost Spreadsheet) in its entirety with the form attached hereto as Annex F;

The Borrower acknowledges that none of the foregoing amendments will satisfy the requirement of Section 10.23(a)(iv) (Interim Agreement Prior to Completion Assessment and Replacement EPC Arrangements).

(a) (i) waive compliance with Section 2.2.3(a) (Mechanics for Requesting Advances; Advance Notice), solely with respect to the delivery of the Advance Notice for the March 2019 Advance less than twenty (20) Business Days prior to the Requested Advance Date for the March 2019 Advance and (ii) agree that the Advance Notice for the March 2019 Advance may instead be submitted no later than six (6) Business Days prior to the Requested Advance Date for the March 2019 Advance (i.e., by March 7, 2019);
