We, the Issuing Bank, hereby certify that as of the Date of Issuance of this Irrevocable Standby Letter of Credit our Senior Unsecured Debt is rated “A” or better by S&P Global Ratings (“S&P”) if rated by S&P, “A2” or better from Moody’s Investors Service (“Moody’s”) if rated by Moody’s, and “A” or better by Fitch Ratings (“Fitch”) if rated by Fitch. We hereby certify that our Senior Unsecured Debt is rated by at least two of S&P, Moody’s, and Fitch. If affiliated with a foreign bank, we further certify we are a U.S. branch office of such foreign bank and that as of the Date of Issuance of this Letter of Credit, our Senior Unsecured Debt meets the ratings requirement of this paragraph.

Thus, a bank that has a rating of “A-“ from Fitch is not acceptable as an Issuing Bank for the Post-Bid Letter of Credit. As specified in the certification above, if a bank is rated by Fitch, the bank must be rated “A” or better.

A Bidder may also meet the collateral requirements under the applicable supplier contract by posting cash.
