SECTION 2.20.  Extension  of Maturity Date.  (a)  The Borrower may, by notice to the Administrative Agent (which shall promptly notify the Lenders), request that each Lender extend such Lender’s Maturity Date to a date that is one year after the Maturity Date then in effect for such Lender (it being agreed at no time shall any such extended Maturity Date result in a total maturity length ofbe more than 5five years under this Agreement fromafter the effective date of any such extension) (the “Existing Maturity Date”).

(b)          Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not later than the date that is 15 days after the date on which the Administrative Agent received the Borrower’s extension request (the “Lender Notice Date”), advise the Administrative Agent whether or not such Lender agrees to such extension (each Lender that determines to so extend its Maturity Date, an “Extending Lender”, and each other Lender, a “Non-Extending Lender”), provided that any Lender that does not so advise the Administrative Agent on or before the Lender Notice Date shall be deemed to be a Non- Extending Lender. The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section promptly upon receiving notice thereof from such Lender. The election of any Lender to agree to such extension shall not obligate any other Lender to so agree, and it is understood and agreed that no Lender shall have any obligation whatsoever to agree to any request made by the Borrower for extension of the Maturity Date.

(c)          The Borrower shall have the right, but shall not be obligated, on or before the Maturity Date applicable to any Non-Extending Lender to replace such Non-Extending Lender with, and add as “Lenders” under this Agreement in place thereof, one or more financial institutions (each, an “Additional Commitment Lender”) in accordance with the procedures set forth in Section 2.18(b). Prior to any Non-Extending Lender being replaced by one or more Additional Commitment Lenders pursuant hereto, such Non-Extending Lender may elect, in its sole discretion, by giving irrevocable notice thereof to the Administrative Agent and the Borrower (which notice shall set forth such Lender’s new Maturity Date), to become an Extending Lender.

(d)          If (and only if) the total of the Commitments of the Lenders that have agreed to extend their Maturity Date and the new or increased Commitments of any Additional Commitment Lenders is more than 50% of the aggregate amount of the Commitments in effect immediately prior to the applicable Extension Date, then, effective as of the first date on which the foregoing conditions shall have been satisfied (the “Extension Date”), the Maturity Date of each Extending Lender and of each Additional Commitment Lender shall be extended to the date that has been requested by the Borrower pursuant to (and approved in accordance with) this Section, and each Additional Commitment Lender shall thereupon become a Lender for all purposes of this Agreement and shall be bound by the provisions of this Agreement as a Lender hereunder and shall have the obligations of a Lender hereunder, provided that any extension of any Maturity Date pursuant to this Section shall be subject to the receipt by the Administrative Agent of a certificate dated such date and executed by a Financial Officer of the Borrower certifying that the conditions set forth in paragraphs (a) and (b) of Section 4.02 are satisfied.
