Notwithstanding anything to the contrary contained herein, any Bank (a "Designating Lender") may grant to an Eligible Designee identified as such (and as a Designated Lender) in writing from time to time by such Designating Lender to the Administrative Agent and the Borrowers, the option to provide to the Borrowers all or any part of any Loan that such Granting Bank would otherwise be obligated to make to any Borrower pursuant to this Agreement; provided that nothing herein shall constitute a commitment by such Designated Lender to make any Loan and (ii) if a Designated Lender elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Designating Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by a Designated Lender hereunder shall utilize the Committed Amount of the Designating Lender to the same extent, and as if, such Loan were made by such Designating Lender. Each party hereto hereby agrees that no Designated Lender shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Designating Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any Designated Lender, it will not institute against, or join any other person in -8- instituting against, such Designated Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. As to any Loans or portion thereof made by it, each Designated Lender shall have all the rights that a Bank making such Loans or portion thereof would have had under this Agreement and otherwise; provided that (i) its voting rights under this Agreement shall be exercised solely by its Designating Lender, (ii) its Designating Lender shall be deemed to hold its relevant Note as agent for its Designated Lender to the extent of the Loans or portion thereof funded by such Designated Lender and (iii) the designation of a Designated Lender and the funding of Loans by a Designated Lender shall in no event (x) subject any of the Borrowers to any delay in the making of a Loan, (y) cause or give rise to any obligation of any of the Borrowers to indemnify or hold harmless such Designated Lender or any other person (including without limitation pursuant to Sections 2.11 and 9.04 of this Agreement) except to the extent such obligation would have arisen in favor of the Designating Lender or another person if the Designating Lender (rather than such Designated Lender) had made all of such Designated Lender's Loans and such Designated Lender had not been designated as such hereunder, or (z) render the performance of any provision of the Agreement illegal, void or unenforceable under any provision of law. Each Designating Lender shall act as administrative agent for its Designated Lender and give and receive notices and other communications on behalf of its Designated Lender. Any payments for the account of any Designated Lender shall be paid to its Designating Lender as administrative agent for such Designated Lender and neither the Borrowers nor either Agent shall be responsible for any Designating Lender's application of such payments. In addition, any Designated Lender may (i) with notice to, but without the prior written consent of, XL Capital and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Designating Lender or to any -9- financial institutions (consented to by XL Capital and the Administrative Agent) providing liquidity and/or credit support to or for the account of such Designated Lender to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans or portions thereof to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such Designated Lender.
