Description Of Bank's Loan Grading Process	The Bank’s loan grading process is as follows: All loans are assigned a loan grade at the time of origination by the relationship manager. Typically, a loan is assigned a loan grade of “pass” at origination. Loan relationships greater than or equal to $500 thousand are reviewed by the Bank’s external loan review provider on an annual basis. Additionally, the Bank’s external loan review provider samples other loan relationships between $100 thousand and $500 thousand with an emphasis on commercial and commercial real estate loans and insider loans. The Bank’s internal loan review department samples approximately 33 percent of all other loan relationships less than $500 thousand on an annual basis for review. If a loan is delinquent 60 days or more or a pattern of delinquency exists, the loan will be selected for review. Generally, all loans on the Bank’s internal watchlist are reviewed annually by internal loan review or external loan review providers.
