accounting principles, Signal Corp and First Shenango expect that costs incurred to effect the Merger, which would include transaction costs of the Merger and costs to combine operations, will be deducted in determining net income in the period in which they are incurred. Adjustments to conform the accounting policies of the entities are reflected in these Unaudited Pro Forma Condensed Combined Financial Statements and are discussed in the following notes. The pro forma financial statements do not give effect to any cost savings which may be realized in connection with the consolidation of the respective operations of Signal Corp and First Shenango. (1) Transaction costs of the Merger (primarily investment banker and other professional fees) and costs to combine operations are expected to be in the $8.6 million to $9.5 million range (the "Expected Range"_). The Unaudited Pro Forma Condensed Combined Statements of Income do not reflect these charges. The Unaudited Pro Forma Condensed Combined Statement of Financial Condition reflects these charges at the mid-point of the Expected Range ($9.1 million). It is anticipated that these charges will be incurred and recognized by Signal Corp and First Shenango and substantially paid by the end of 1998. The following table provides details of the estimated charges by type of cost: Type of Cost Expected Range of Pre-Tax Cost - ------------------------------------------------------------------------------------------------------- Transaction costs 1.8 million Adjustments to conform accounting policies .50 to .75 million Additional loan loss allowance 1.8 million Costs to combine operations: Employee Stock Ownership Plan termination costs 1.6 million Duplicative systems and operating costs 2.4 to 2.8 million Other costs incidental to the Merger .50 to .75 million Total Merger-related adjustments 8.6 to 9.5 million (2) Represents the expected after-tax effect of the pro forma adjustments, as described in note (1) above, assuming a federal income tax rate of 35%. Transaction costs are not fully deductible for federal income tax purposes. (3) Represents the expected income tax benefit associated with the pro forma adjustments. (4) Represents the exercise of options covering 5,000 shares of First Shenango Common Stock at $20.75 per share and the exercise of options covering 94,339 shares of First Shenango Common Stock at $10.00 per share which are expected to occur prior to the closing of the Merger pursuant to written commitments to exercise executed by the optionees. (5) The pro forma combined per share data has been computed based on the combined historical income and on the combined weighted average common and common equivalent shares outstanding assuming the issuance of 1.42875 shares of Signal Corp Common Stock for each share of First Shenango Common Stock based on the Exchange Ratio. Shares assumed to be issued in computing the weighted number of common and common equivalent shares outstanding used to compute basic per share earnings for the three months ended March 31, 1998 and 1997 and for the years ended December 31, 1997, 1996 and 1995 were 2,863,000, 2,810,000, 2,836,000, 3,083,000, and 3,116,000, respectively. (6) Share and per share data for Signal Corp. has been retroactively restated for a 25% stock dividend approved in April 1998. 8 9 (7) The following table reflects the assumed conversion of First Shenango Common Stock into Signal Corp Common Stock pursuant to the Merger if the Merger were to be effective as of March 31, 1998: Pre-Merger Shares Post-Merger Shares Outstanding Outstanding First Shenango common shares issued 2,343,098 2,343,098 Less Treasury stock 274,091 174,752 Cancellation of shares held in First Shenango Management Bonus Plan reserves -- (10,367) ---------------- ------------------ First Shenango common shares issued and outstanding 2,069,007 2,157,979 ================ Exchange Ratio x 1.42875 ------------------ First Shenango post-Merger shares outstanding 3,088,212 ================== Treasury shares will be issued upon the exercise of options covering 99,339 shares of First Shenango Common Stock.
