REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Stockholders and Board of Directors of USBANCORP, Inc.: We have reviewed the accompanying consolidated balance sheets of USBANCORP, Inc. (a Pennsylvania corporation) and Subsidiaries as of March 31, 1994 and 1993, and the related consolidated statements of income, changes in stockholders' equity and cash flows for the three-month period ended March 31, 1994 and 1993. These financial statements are the responsibility of the company's management. We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion. Based on our review, we are not aware of any material modifications that should be made to the financial statements referred to above for them to be in conformity with generally accepted accounting principles. We have previously audited, in accordance with generally accepted auditing standards, the consolidated balance sheet of USBANCORP, Inc. as of December 31, 1993, and, in our report dated January 28, 1994, we expressed an unqualified opinion on that statement. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 1993, is fairly stated, in all material respects, in relation to the balance sheet from which it has been derived.
