SECTION 2.20. Increase in Commitments. (a) Alcoa may from time to time, by written notice to the Administrative Agent, executed by Alcoa and one or more financial institutions (any such financial institution referred to in this Section being called a “Prospective Lender”), which may include any Lender, cause the Commitments of the Prospective Lenders to be increased (or cause Commitments to be extended by the Prospective Lenders, as the case may be) in an amount for each Prospective Lender set forth in such notice; provided, however, that (i) the amount of any such increase in the Commitments shall be no less than $25,000,000, (ii) the sum of the aggregate amount of increases in Commitments under this Section 2.20, the aggregate amount of increases in commitments under Section 2.20 of the 2003 Five-Year Credit Agreement and the aggregate amount of increases in commitments under Section 2.20 of the 2005 Five-Year Credit Agreement, in each case during the term of this Agreement, shall not exceed $500,000,000, (iii) each Prospective Lender, if not already a Lender hereunder, shall be subject to the approval of the Administrative Agent (which approval shall not be unreasonably withheld) and (iv) each Prospective Lender, if not already a Lender hereunder, shall become a party to this Agreement by completing and delivering to the Administrative Agent a duly executed Accession Agreement. Increases in Commitments and new Commitments created pursuant to this Section shall become effective (A) in the case of Prospective Lenders already parties hereto, on the date specified in the notice delivered pursuant to this Section and (B) in the case of Prospective Lenders not already parties hereunder, on the effective date of the Accession Agreement. Upon the effectiveness of any Accession Agreement to which any Prospective Lender is a party, (i) such Prospective Lender shall thereafter be deemed to be a party to this Agreement and shall be entitled to all rights, benefits and privileges accorded a Lender hereunder and subject to all obligations of a Lender hereunder and (ii) Schedule 2.01 shall be deemed to have been amended to reflect the Commitment of the additional Lender as provided in such Accession Agreement. Upon the effectiveness of any increase pursuant to this Section in the Commitment of a Lender already a party hereunder, Schedule 2.01 shall be deemed to have been amended to reflect the increased Commitment of such Lender. Notwithstanding the foregoing, no increase in the aggregate Commitments (or in the Commitment of any Lender) shall become effective under this Section unless (i) the Administrative Agent shall have received documents consistent with those delivered under paragraphs (a) and (c) of Section 4.01 as to the corporate power and authority of Alcoa to borrow hereunder after giving effect to such increase and (ii) on the date of such increase, the conditions set forth in paragraphs (b) and (c) of Section 4.02 shall be satisfied (with all references in such paragraphs to a Borrowing being deemed to be references to such increase) and the Administrative Agent shall have received a certificate to that effect dated such date and executed by a Financial Officer of Alcoa. Following any increase of a Lender’s Commitment or any extension of a new Commitment pursuant to this paragraph, any Loans outstanding prior to the effectiveness of such increase or extension shall continue outstanding until the ends of the respective Interest Periods applicable thereto, and shall then be repaid or refinanced with new Loans made pursuant to Section 2.01; provided that notwithstanding anything to the contrary in this Agreement, the conditions to borrowing set forth in Section 4.02 shall not apply to such new Loans to the extent they are in a principal amount not greater than that of the Loans being refinanced. Notwithstanding anything to the contrary in this Agreement, no Lender shall be required to be a Prospective Lender.

In case any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, none of the parties hereto shall be required to comply with such provision for so long as such provision is held to be invalid, illegal or unenforceable, but the validity, legality and enforceability of the remaining provisions contained herein and in the Credit Agreement shall not in any way be affected or impaired. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8. Notices. All communications and notices hereunder shall be in writing and given as provided in Section 10.01 of the Credit Agreement. All communications and notices hereunder to the Acceding Lender shall be given to it at the address set forth under its signature hereto.
