AND SUBSIDIARIES UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENTS OF INCOME SUMMARY The following Unaudited Pro Forma Condensed Combined Statements of Income give effect to UST's acquisition of Affiliated by combining the results of operations of UST for the three months ended March 31, 1998, with the results of operations of Affiliated for the three months ended March 31, 1998, on a pooling of interests basis, assuming the combination, which was consummated on August 7, 1998, had occurred as of January 1, 1998. Basic and Diluted earnings per share and weighted average common shares outstanding are based on the exchange ratio of 1.41 shares of UST for each share of Affiliated as specified in the Affiliation Agreement. The Unaudited Pro Forma Condensed Combined Statements of Income also give effect to the acquisition by UST of Somerset assuming the combination, which was consummated on July 20, 1998 and accounted for as a pooling of interests, had occurred as of January 1, 1998. The Unaudited Pro Forma Condensed Combined Statements of Income should be read in conjunction with the Unaudited Pro Forma Condensed Combining Balance Sheet appearing elsewhere in this Form 8-K. The Unaudited Pro Forma Condensed Combining Balance Sheet reflects an after-tax charge for estimated merger and reorganization expenses of $8.7 million ($12.0 million pre-tax) in connection with the Affiliated acquisition and an after-tax charge for estimated merger and reorganization expenses of $5.3 million ($7.5 million pre-tax) in connection with the Somerset acquisition; however, since these expenses are nonrecurring, they have not been reflected in the Unaudited Pro Forma Condensed Combined Statements of Income.

The Unaudited Pro Forma Condensed Combined Statements of Income are presented for information purposes only and are not necessarily indicative of the combined results of operations that would have occurred if the combination of UST and Affiliated had been consummated on January 1, 1998 or which may be obtained in the future. 4 UST CORP.

Accordingly, pro forma financial information assumes that the combinations were consummated as of the beginning of the periods indicated herein. Certain reclassifications have been made to the accounts of Affiliated and Somerset in the accompanying Unaudited Pro Forma Condensed Combining Balance Sheet and Unaudited Pro Forma Condensed Combined Statements of Income to conform to UST presentation. Pro forma results of operations do not reflect nonrecurring items of income and expense relating directly from the combinations. The effect of estimated one-time, after-tax charges of $8.7 million ($12.0 million pre-tax) recorded in connection with the Affiliated acquisition has been reflected in the accompanying Unaudited Pro Forma Condensed Combining Balance Sheet as a reduction in retained earnings, and an increase in other liabilities, net of a 40 percent tax benefit of $3.3 million, after excluding $3.8 million of nondeductible expense. The effect of estimated one-time, after-tax charges of $5.3 million ($7.5 million pre-tax) recorded in connection with the Somerset acquisition has been reflected in the accompanying Unaudited Pro Forma Condensed Combining Balance Sheet as a reduction in retained earnings, and an increase in other liabilities, net of a 40 percent tax benefit of $2.2 million, after excluding $2.1 million of nondeductible expense. These charges have not been reflected in the Unaudited Pro Forma Condensed Combined Statements of Income since they are nonrecurring. The pro forma financial information does not give effect to any cost savings in connection with the acquisitions. NOTE 2: The pro forma stockholders' investment accounts of UST and Somerset have been adjusted in the accompanying Unaudited Pro Forma Condensed Combining Balance Sheet to reflect the issuance of shares of UST Common Stock in exchange for all of the outstanding shares of Somerset Common Stock. The number of shares of UST Common Stock issued pursuant to the acquisition of Somerset were based upon the number of Somerset shares outstanding as of July 20, 1998. The exchange ratio of 0.19 shares of UST Common Stock for each share of Somerset Common Stock is specified in the Affiliation Agreement. The differences between the par value of the UST Common Stock issued ($0.625 per share) and the par value of the Somerset Common Stock acquired ($1.00 per share) has been recorded to Additional paid-in capital. The pro forma stockholders' investment accounts of UST, as adjusted for Somerset, and Affiliated have been adjusted in the accompanying Unaudited Pro Forma Condensed Combining Balance Sheet to reflect the issuance of shares of UST Common Stock in exchange for all of the outstanding shares of Affiliated Common Stock. The number of shares of UST Common Stock issued pursuant to the acquisition of Affiliated were based upon the number of Affiliated shares outstanding as of August 7, 1998. The exchange ratio of 1.41 shares of UST Common Stock for each share of Affiliated Common Stock is specified in the Affiliation Agreement. The difference between the par value of the UST Common Stock issued ($0.625 per share) and the par value of the Affiliated Common Stock acquired ($0.01 per share) has been recorded to Additional paid-in capital. 6 NOTE 3: UST classifies its investments in debt and equity securities as "Securities Available-for-Sale" in accordance with the provisions of Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities." Accordingly, such securities are carried at fair value, with unrealized gains and losses, net of tax, reported as a separate component of Stockholders' Investment. In order to maintain UST's existing interest rate risk position, the securities in the Affiliated and Somerset portfolios, which are designated as Held-to-Maturity and are carried at cost adjusted for the amortization of premium and accretion of discount, were redesignated as Available-for-Sale upon consummation of the acquisitions. At March 31, 1998, the Available-for-Sale designation would add approximately $1.2 million and $334 thousand, respectively, to the Stockholders' Investment accounts of Affiliated and Somerset. NOTE 4: Pro forma earnings per share amounts in the accompanying Unaudited Pro Forma Condensed Combined Statements of Income are based on the weighted average number of Basic and Diluted common shares of the constituent companies outstanding during each period assuming an exchange ratio of 1.41 shares of UST Common Stock for each share of Affiliated Common Stock and an exchange ratio of 0.19 shares of UST Common Stock for each share of Somerset Common Stock.
