2 Item 7. FINANCIAL STATEMENTS AND EXHIBITS. The following financial statements and exhibits are filed as part of this Report: (a) Financial statements of Kwangju Packaging business of Anam Semiconductor, Inc. ("K4") (i) Financial statements of K4 for the year ended December 31, 1998 were previously filed with this report on April 26, 1999 and are incorporated herein by reference.

3 (b) Pro forma financial information. (i) Pro forma financial information for the year ended December 31, 1998. (ii) Pro forma financial information for the three month period ended March 31, 1999. UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA The unaudited pro forma consolidated balance sheets as of March 31, 1999 and December 31, 1998 give effect to the Transaction as if it had occurred on March 31, 1999 and December 31, 1998, respectively. The unaudited pro forma consolidated income statements for the three months ended March 31, 1999 and the year ended December 31, 1998 give effect to the Transaction as if it had occurred on January 1, 1999 and January 1, 1998, respectively. We have used the purchase method of accounting in accordance with APB Opinion No. 16 to prepare the accompanying unaudited pro forma consolidated financial information. Under this method of accounting, we allocated the $575.0 million aggregate purchase price of K4, plus $7.0 million of assumed employee benefit liabilities, to specific assets acquired and liabilities assumed based on their estimated fair values. The purchase price does not include $20.3 million of estimated transaction fees and expenses. The balance of the purchase price of K4 represents the excess of cost over net assets acquired. We have estimated the preliminary fair value of K4's assets and liabilities based on a draft appraisal. We will determine the final allocation of the purchase price based upon the receipt of the final appraisal. We have not completed all of the work required to fully evaluate the assets acquired and liabilities assumed as of the date of this filing. Accordingly, we may not finalize purchase accounting adjustments for up to one year after the closing. We have prepared the unaudited pro forma consolidated financial information in accordance with U.S. GAAP. These principles require us to make extensive use of estimates and assumptions that affect: (1) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (2) the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The unaudited pro forma consolidated income statements for the three months ended March 31, 1999 and the year ended December 31, 1998 is not necessarily indicative of our future operating results. You should read the unaudited pro forma consolidated financial information in conjunction with our consolidated financial statements and the notes thereto and the financial statements of K4 and the notes thereto, included elsewhere in other filings.

5 - --------------------------- (a) We have eliminated the processing charges that we have paid to ASI for services performed for us at the K4 factory under our supply agreements. Because we currently sell substantially all of K4's services, the net revenues from the sale of K4's services to our customers are already reflected in our historical net revenues. (b) Represents amortization of goodwill related to the Acquisition, assuming a ten-year life. (c) Represents change in depreciation expense based on adjusted book values of acquired property, plant and equipment. (d) Represents the elimination of interest expense and foreign currency losses related to debt of K4, which we will not assume as part of the Acquisition. (e) Represents: (1) interest expense on $625,000 of Notes at an assumed weighted average interest rate of 9.65% and (2) $2,593 of amortization of deferred debt issuance costs, which are amortized over the life of the respective debt. (f) Represents an income tax benefit due to the pro forma adjustment for interest expense. (g) Prior to our reorganization in April 1998, our predecessor, AEI, elected to be taxed as an S Corporation under the Code. As a result, AEI did not recognize any provision for federal income tax expense during the period presented. In accordance with applicable SEC regulations, we have presented a pro forma adjustment (unaudited) for income taxes to reflect the additional U.S. federal income taxes that we would have recorded if AEI had been a C Corporation during this period. We used 106,221 shares of common stock to compute basic net income per common share and 116,596 shares of common stock and common stock equivalents to compute diluted net income per common share.
