deterioration  in  credit  quality  and/or a  reduced  demand  for  credit;  (5)

realized within the expected time frames; (8) deposit attrition,  customer loss,
or revenue loss following  pending mergers and  acquisitions may be greater than
expected;  (9)  competitors  may have greater  financial  resources  and develop
products that enable such competitors to compete more successfully than NBT; and
