Description Of Bank's Loan Grading Process	The Banks 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 Banks external loan review provider on an annual basis. The Banks 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 Banks internal watchlist are reviewed annually by internal loan review or external loan review providers.
