IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money

laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for the Borrower: When a borrower opens an account, if such borrower is an individual, the Bank will ask for such borrower’s name, residential address, tax identification number, date of birth, and other information that will allow the Bank to identify such borrower; and, if such borrower is not an individual, the Bank will ask for such borrower’s name, tax identification number, business address, and other information that will allow the Bank to identify such borrower. The Bank may also ask, if such borrower is an individual, to see such borrower’s driver’s license or other identifying documents; and, if such borrower is not an individual, to see such borrower’s legal organizational documents or other identifying documents.

     The Status in effect on any date is based on the Moody’s Rating and S&P Rating in effect at the close of business on such date.

     For the purposes of the foregoing (but subject to the final paragraph of this Pricing Schedule):

     “Level I Status” exists at any date if, on such date, the Borrower’s Moody’s Rating is A2 or better or the Borrower’s S&P Rating is A or better.

     “Level II Status” exists at any date if, on such date, (i) Level I Status does not exist and (ii) the Borrower’s Moody’s Rating is A3 or better or the Borrower’s S&P Rating is A- or better.

     “Level III Status” exists at any date if, on such date, (i) neither Level I Status nor Level II Status exists and (ii) the Borrower’s Moody’s Rating is Baa1 or better or the Borrower’s S&P Rating is BBB+ or better.

     “Level IV Status” exists at any date if, on such date, (i) none of Level I Status, Level II Status or Level III Status exists and (ii) the Borrower’s Moody’s Rating is Baa2 or better or the Borrower’s S&P Rating is BBB or better.

     “Level V Status” exists at any date if, on such date, (i) none of Level I Status, Level II Status, Level III Status or Level IV status exists and (ii) the Borrower’s Moody’s Rating is Baa3 or better or the Borrower’s S&P Rating is BBB- or better.

     “Level VI Status” exists at any date for Borrower if, on such date, none of Level I Status, Level II Status, Level III Status, Level IV Status or Level V Status exists.

     “Status” means Level I Status, Level II Status, Level III Status, Level IV Status, Level V Status or Level VI Status.

     If the S&P Rating and the Moody’s Rating for the Borrower create a split-rated situation and the ratings differential is one level, the higher rating will apply. If the differential is two levels or more, the intermediate rating at the midpoint will apply. If there is no midpoint, the higher of the two intermediate ratings will apply. If Borrower has no Moody’s Rating or no S&P Rating, Level VI Status shall exist.
