SECOND AMENDMENT TO CREDIT AGREEMENT

THIS SECOND AMENDMENT TO CREDIT AGREEMENT, dated as of October 31, 2012 (this “Amendment”), amends the Credit Agreement, dated as of December 8, 2011 (the “Credit Agreement”) among Portland General Electric Company (the “Borrower”), the financial institutions from time to time parties thereto as lenders (collectively, together with their respective successors and assigns, the “Lenders”) and Bank of America, N.A., as administrative agent for the Lenders (in such capacity, the “Agent”). Capitalized terms used but not otherwise defined herein have the meanings assigned to such terms in the Credit Agreement.

WHEREAS, the parties hereto desire to amend the Credit Agreement as provided herein.

NOW, THEREFORE, the parties hereto agree as follows:

SECTION 1    Amendments. Subject to the conditions precedent set forth in Section 3, the Credit Agreement is amended as set forth below:

1.1    Amendment to Section 2.18.    Section 2.18 of the Credit Agreement is amended in its entirety to read as follows:

2.18    Extension of Final Termination Date. The Borrower may, up to two times during the term of this Agreement, request a one-year extension of each Lender's Scheduled Termination Date by submitting a request for an extension to the Agent (an “Extension Request”) no more than ninety (90) days, but not less than sixty (60) days, prior to any anniversary of the Effective Date commencing with the first anniversary thereof (the “Extension Date”). Any Extension Request shall specify the date (which must be at least thirty (30) days after the Extension Request is delivered to the Agent but no later than thirty (30) days prior to the Extension Date) as of which the Lenders must respond to such Extension Request (the “Response Date”). Promptly upon receipt of an Extension Request, the Agent shall notify each Lender of the contents thereof. Each Lender shall, not later than the Response Date for any Extension Request, deliver a written response to the Agent approving or rejecting such Extension Request (and any Lender that fails to deliver such a response by the Response Date shall be deemed to have rejected such Extension Request). If (i) Lenders that collectively have a Pro Rata Share of more than 50% approve an Extension Request (which approval shall be at the sole discretion of each Lender) and (ii) all of the Aggregate Outstanding Credit Exposure shall have been paid in full on the Extension Date, then the then-effective Final Termination Date, and the Scheduled Termination Date for each such approving Lender, shall be extended to the date that is one year after the then-effective Final Termination Date or, if such date is not a Business Day, to the next preceding Business Day (but the then-effective Scheduled Termination Date for each other Lender shall remain unchanged). The Agent shall promptly (and in any event not later than twenty-five (25) days prior to the Extension Date for each of the Lenders) notify the Borrower, in writing, of the Lenders' elections pursuant to this Section 2.18. If Lenders that collectively have a Pro Rata Share of 50% or more reject an Extension Request, then the Final Termination Date, and the Scheduled Termination Date of each Lender, shall remain unchanged. The Borrower may elect to replace any declining Lender under this Section 2.18 pursuant to the terms of Section 2.17. Prior to the effectiveness of any Extension Request under this Section 2.18, the Agent shall have received evidence, in form and substance reasonably satisfactory to the Agent, that the Borrower has obtained the approval of the Public Utility Commission of Oregon in connection with such Extension Request.

1.2    Amendment to Section 6.10(xvi). Section 6.10(xvi) of the Credit Agreement is amended in its entirety to read as follows:

(xvi)    Liens, in addition to those listed in clauses (i) through (xv) above, incurred in the ordinary course of the Borrower's business on collateral with a market value that in the aggregate does not exceed $50,000,000.
