(b) Dispositions of System Assets. The Borrower shall not, without first complying with the requirements of Section 9.1, request the release of capital assets that constitute utility plant from the lien of the Indenture pursuant to Section 5.2 of the Indenture if (taking into account any substantially contemporaneous or otherwise related purchase, construction, lease or other acquisition of similar property that is subject to the lien of the Indenture) there will result a decrease in the generating capacity of the System or any generating plant by more than 5% if the aggregate net book value of all such assets released from the lien of the Indenture (i) in the current fiscal year of the Borrower is greater than 5% of the Borrower’s Total Utility Plant or (ii) in the current and two immediately preceding fiscal years of the Borrower is greater than 10% of the Borrower’s Total Utility Plant.

(c) Legal Requirements. The requirements of this Section 6.2 shall not apply to any purchase, construction, lease or other acquisition, or any sale, transfer, lease or other disposition, of capital assets to the extent that any of the foregoing is required to comply with “Legal Requirements” (as defined in the Wholesale Power Contract). No such purchase, construction, lease or other acquisition and no such sale, transfer, lease or other disposition shall be considered in calculating the aggregate limitations specified in Subsections (a) or (b) hereof.

(d) Highest Oversight Period. During a Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, purchase, construct, lease or otherwise acquire, or sell, transfer, lease or otherwise dispose of, any capital asset, or enter into any agreement therefor.

At any time an Event of Default, or an event which with the passage of time or the giving of notice, or both, would become an Event of Default, occurs and is continuing, the Borrower

shall not, without the prior written approval of the RUS, enter into an employment relationship with any person to serve as General Manager unless such employment shall first have been approved by the RUS. If an Event of Default, or an event which with the passage of time or the giving of notice, or both, would become an Event of Default, occurs and is continuing and the RUS requests the Borrower to terminate the employment of its General Manager, the Borrower shall do so within thirty (30) days after the date of such request.

(v) any contract for construction or procurement or for architectural and engineering services in connection with a new generating facility if the project will be financed in whole or in part by the RUS.

(b) Terminations. The Borrower shall not, without first complying with the requirements of Section 9.1, exercise any option to terminate any contract, including, without limitation, any Wholesale Power Contract, if such contract, based upon its nature, remaining term (not taking into account any option of the Borrower to terminate) and size, would be

19 required to be approved by the RUS pursuant to Subsection (a) above if the Borrower were to have entered into such contract on the proposed termination date. The Borrower further agrees at the written direction of the RUS to exercise any option to terminate a contract if the exercise by the Borrower of that option would require compliance with the requirements of Section 9.1 pursuant to the immediately preceding sentence; provided, however, the Borrower shall not be required to exercise any such option to terminate if such exercise could reasonably be expected to have a Material Adverse Effect. For the purpose of illustration only, and not by way of limitation, the Borrower shall be required to comply with the requirements of Section 9.1 before terminating, and the RUS can require the Borrower to terminate, in any year before year seven (7) thereof, a ten (10) year contract for the sale of electric power and energy that exceeds ten percent (10%) of the Borrower’s peak demand because the portion of the contract to be terminated meets the standards of Subsection (a)(ii) above (i.e., a term greater than three (3) years for the committed sale of electric power and energy that exceeds ten percent (10%) of the Borrower’s peak demand). The Borrower can terminate without first complying with the requirements of Section 9.1, and the RUS cannot require the Borrower to terminate, that same contract after year seven (7) thereof.

(c) Highest Oversight Period. During a Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, enter into or amend or modify any of the contracts of the type described in this Section 6.4, regardless of duration or size.

(d) Determination of Term. For purposes of this Section 6.4, the term of any contract shall be determined in accordance with this Subsection. The term of any contract shall be the period during which performance (other than payment) is to occur and not the period commencing when such contract is executed. The term of any contract shall be based upon the period prior to the first date upon which the Borrower could, at its option, terminate the contract (taking into account any notice period required for termination), unless the exercise of such termination right could reasonably be expected to have a Material Adverse Effect.

(e) Amendments; Extensions. Any amendment or modification to an existing contract (including an extension thereof) shall be governed by this Section 6.4 only to the extent such specific amendment or modification (and not the contract as a whole), judged as if it were a separate contract, would be required to be approved by the RUS pursuant to Subsection (a) above.

Section 6.5 Limitations on Loans, Investments and Other Obligations

The Borrower shall not, without first complying with the requirements of Section 9.1, make any Investment, except (i) Investments made for the purpose of funds management that are made pursuant to an investment policy approved by the Borrower’s Board of Directors, a copy of which has been provided to the RUS, (ii) Investments specifically approved by the RUS in writing under this clause (ii), (iii) retained earnings or patronage of Subsidiaries, (iv) patronage allocated to the Borrower as a result of transactions in the ordinary course of business with cooperatives, such as, National Rural Utilities Cooperative Finance Corporation and CoBank, ACB, (v) investments set forth in RUS Regulations (7 C.F.R. § 1717.655, as such RUS Regulations exist on the date hereof) as excluded from computations of the amounts and type of Investments for which RUS approval is required, and (vi) other Investments (valued at the initial

cost thereof) that do not in the aggregate with all other Investments other than Investments described in clauses (i) through (v) above exceed fifteen percent (15%) of the Borrower’s Total Utility Plant; provided, however, that during an Increased Oversight Period, or Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, make any additional Investments of the type described in clause (vi) above.

(f) liens, pledges, security interests, charges and encumbrances with respect to deposit, brokerage, commodity and other similar accounts to the extent such liens, pledges, security interests, charges and encumbrances do not secure indebtedness for borrowed money other than indebtedness incurred in connection with acquiring securities or other investments deposited in any such account.

The term “dissolution or liquidation of the Borrower,” as used in this Subsection (h), shall not be construed to include the cessation of the corporate existence of the Borrower resulting either from a merger or consolidation of the Borrower into or with another corporation following a transfer of all or substantially all its assets as an entirety, under the conditions permitting such actions; and

(i) Indenture. Any Event of Default as set forth in Section 8.1 of the Indenture and any event (as set forth in such Section 8.1) that with the giving of notice or the passage of time, or both, could become an Event of Default.

Section 8.1 Remedies

Upon the occurrence of an Event of Default, then the RUS may pursue all rights and remedies available to the RUS that are contemplated by this Agreement in the manner, upon the conditions and with the effect provided in this Agreement, including, but not limited to, a suit for specific performance, injunctive relief or compensatory damages. The RUS is hereby authorized, to the maximum extent permitted by applicable law, to demand specific performance of this Agreement at any time when the Borrower shall have failed to comply with any provision of this Agreement applicable to it. The Borrower hereby irrevocably waives, to the maximum extent permitted by applicable law, any defense based on the adequacy of a remedy at law that might be asserted as a bar to such remedy of specific performance. Nothing herein shall limit the right of the RUS to pursue all rights and remedies available to a creditor at law or in equity following the occurrence of an Event of Default, or any right or remedy available to the RUS as a Holder of an Obligation under the Indenture. Each right, power and remedy of the RUS shall be cumulative and concurrent, and recourse to one or more rights or remedies shall not constitute a waiver of any other right, power or remedy.

Section 8.2 Suspension of Advances

In addition to the rights, powers and remedies referred to in Section 8.1, the RUS may, in its absolute discretion, suspend or terminate the obligation to make or approve Advances

hereunder if (i) any Event of Default, or any occurrence which with the passage of time or giving of notice would be an Event of Default, occurs and is continuing; or (ii) an event shall have occurred that has had or is likely to have a Material Adverse Effect.

This Agreement and the other Loan Documents are intended by the parties to be a complete and final expression of their agreement. However, the RUS reserves the right to waive its rights to compliance with any provision of this Agreement, the RUS Regulations and the other Loan Documents. No amendment, modification, or waiver of any provision hereof or thereof, and no consent to any departure of the Borrower herefrom or therefrom, shall be effective unless approved in writing by the RUS in the form of either RUS Regulations or other writing signed by or on behalf of the RUS, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Any Schedule to this Agreement may be

amended and replaced by attaching a revised Schedule hereto, which revised Schedule shall have been signed by both parties hereto.

Section 9.13 Right of Set Off

Upon the occurrence and during the continuance of any Event of Default, the RUS is hereby authorized at any time and from time to time, without prior notice to the Borrower, to exercise rights of set off or recoupment and apply any and all amounts held or hereafter held, by the RUS or owed to the Borrower or for the credit or account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing hereunder or under the Notes.

Nothing herein is intended to, or shall be deemed to, waive the requirements of any Federal statute or regulation that is applicable to the Borrower independently of any requirement made applicable solely by the RUS Regulations.

(d) Subject to Subsections (b) and (c) above, if on the date of this Agreement, any RUS Regulation conflicts with the terms of this Agreement or the Indenture or imposes additional or different requirements, pursuant to 7 C.F.R. § 1710.113(c)(2), the provisions of this Agreement or the Indenture shall control and the RUS hereby waives compliance by the Borrower with such RUS Regulations.

Environmental Matters

Sierra Club and Coosa River Basin Initiative ▇. ▇▇▇▇▇▇▇ (April 6, 2007)

In April, 2007, the Sierra Club and the Coosa River Basin Initiative appealed two unsuccessful permit challenges involving operating permit renewals for Plants ▇▇▇▇▇▇▇ (co-owned by Oglethorpe Power), ▇▇▇▇▇, ▇▇▇▇▇▇▇ and Branch to the U. S. Court of Appeals for the Eleventh Circuit. The permits were all challenged on the bases of not including compliance schedules to bring the sources into compliance with opacity standards, not including an adequate statement of basis, and, in the cases of ▇▇▇▇▇▇▇ and ▇▇▇▇▇, not including compliance schedules to bring the sources into compliance with Prevention of Significant Deterioration requirements. Oglethorpe intervened in the case on behalf of EPA. A decision in favor of EPA was issued by the Court on September 2, 2008. Sierra Club sought a rehearing by the 11th Circuit Court of Appeals which was denied. It is not known whether the Sierra Club and the Coosa River Basin Initiative will seek a writ of certiorari from the Supreme Court.

Atomic Safety and Licensing Board Proceedings regarding Vogtle Units 3 & 4

Oglethorpe is one of the applicants for an Early Site Permit (“ESP”) with respect to two proposed additional nuclear electric generating units at the Vogtle Electric Generating Plant site, of which Oglethorpe is a part owner. Southern Nuclear Operating Company, on behalf of all of the owners of the proposed additional Plant Vogtle units, filed the ESP application. A petition for intervention in the Vogtle ESP process was filed in December, 2006 by five entities (Center for a Sustainable Coast, Savannah Riverkeeper, Southern Alliance for Clean Energy, Atlanta Women’s Action for New Directions, and Blue Ridge Environmental Defense League) which included seven contentions. The Nuclear Regulatory Commission (“NRC”) appointed an Atomic Safety and Licensing Board (“ASLB”) panel consisting of three administrative law judges to review the contentions and determine admissibility. The ASLB panel held a pre-hearing in February 2007 to review the contentions and rejected all but two of the proposed contentions. The contentions that were admitted alleged 1) that the analysis of impacts on aquatic life in the Savannah River, including impingement, entrainment, chemical and thermal impacts of the proposed cooling system intake and discharge structures was not adequate, including the baseline description of aquatic life in the vicinity of the proposed units to the extent it is related to impacts, and 2) that the Environmental Report (“ER”) fails to fully address alternative cooling technologies, in particular, dry cooling. On September 22, 2008, the above named intervenors filed an additional contention, which was admitted for hearing by the ASLB panel on October 24, 2008 . The contention alleges that the analysis of impacts of potential dredging in the Savannah River in the Environmental Impact Statement was not adequate.

The ASLB panel hearing is scheduled to be held in March 2009, at which time testimony will be heard and the ASLB panel will question Southern Nuclear Operating Company (on behalf of the applicants), the intervenors, and the NRC staff, after which the ASLB panel will provide a final ruling on the contentions.

On May 31, 2008, the NRC docketed an application for a Combined Construction Permit and Operating License (“COL”) submitted by Southern Nuclear Operating Company on behalf of the owners of the proposed Vogtle Units 3 and 4, including Oglethorpe. On September 16, 2008 the NRC issued a Notice of Hearing and of Opportunity to Intervene in the COL application proceeding. On November 17, 2008 an ASLB panel was appointed to preside over the mandatory hearing and any contested hearing that may be ordered in the proceeding. On November 17, 2008 the same intervenors in the Vogtle ESP proceeding filed a joint petition to intervene and three proposed contentions. On December 12, 2008 Southern Nuclear and NRC Staff responded to the contentions in separate Answers opposing the admission of each of the contentions.

Tax Matters

Monroe County Tax Appeal (November 21, 2008)

On November 13, 2008, the Monroe County Board of Assessors issued its assessment of Oglethorpe’s interest in Plant ▇▇▇▇▇▇▇ for the 2008 tax year. While the state used an equalization ratio of 34.55%, Monroe County used an equalization ratio of 40%. On November 21, 2008, Oglethorpe appealed Monroe County’s assessment by filing a notice of appeal with the Monroe County Board of Tax Assessors.

Property Lawsuit

▇▇▇▇▇▇ Creek Noise Lawsuits (February 5, 2007)

On February 5, 2007, twelve lawsuits were filed against Oglethorpe and Smarr EMC in the Superior Court of Polk County, Georgia (Cedartown) by plaintiffs owning property near the ▇▇▇▇▇▇ Creek Energy Facility, which is owned by Smarr EMC and operated by Oglethorpe. The plaintiffs allege that noise and vibration from the plant have interfered with the plaintiffs’ right of quiet enjoyment of their property and diminished their property values. Plaintiffs seek unspecified damages based on various claims, including trespass, nuisance, inverse condemnation and negligence.

Pursuant to the indemnification provision contained in the management agreement between Oglethorpe and ▇▇▇▇▇ EMC, ▇▇▇▇▇ EMC would be responsible for indemnifying Oglethorpe for any liability it may incur in this litigation. ▇▇▇▇▇ EMC has insurance that is expected to cover any liability resulting from these claims.
