Other Events. ------------- EMC Corporation ("EMC"), a Massachusetts corporation, Emerald Merger Corporation ("Merger Sub"), a Delaware corporation and a wholly owned subsidiary of EMC, and Data General Corporation ("DG"), a Delaware corporation, have entered into an Agreement and Plan of Merger dated as of August 6, 1999 (the "Merger Agreement") pursuant to which, among other things, Merger Sub would merge with and into DG with DG as the surviving corporation (the "Merger"). At the effective time of the Merger, each share of DG common stock issued and outstanding (other than shares held by DG, EMC or any wholly owned subsidiary of EMC), will be converted into the right to receive .3262 of a share of EMC common stock, subject to certain adjustments; provided, however, that in the event the average of the mean high and low per share trading prices on the New York Stock Exchange of shares of EMC common stock for each of the 20 consecutive trading days ending on the fifth day prior to the meeting of the stockholders of DG to consider approval and adoption of the Merger Agreement and the merger (the "Pre-Closing Average Price") is greater than $66.0625, then the exchange ratio shall be adjusted so that each share of DG common stock is converted into the right to receive a number of shares of EMC common stock equal to the quotient obtained by dividing (A) $21.55 by (B) the Pre-Closing Average Price. Simultaneously with the execution of the Merger Agreement, EMC and DG entered into a stock option agreement (the "Stock Option Agreement"), pursuant to which, among other things, DG granted to EMC a contingent irrevocable option to purchase up to 10,177,850 shares (the "Option Shares") of DG common stock, including any associated rights to purchase shares of DG common stock pursuant to the Renewed and Restated Rights Agreement between DG and The Bank of New York, at a price of $19.58 per Option Share, subject to certain adjustments. Completion of the transactions contemplated by the Merger Agreement and the Stock Option Agreement is subject to the approval of DG stockholders and appropriate regulatory review, and is expected to occur before the end of 1999. The merger is intended to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code and as a "pooling of interests" in accordance with generally accepted accounting principles for financial accounting purposes. Copies of the Merger Agreement and the Stock Option Agreement are attached hereto as Exhibits 2.1 and 10.1, respectively, and are incorporated herein by reference. A copy of a press release issued by EMC and DG announcing the execution of the Merger Agreement is attached hereto as Exhibit 99.1 and is also incorporated herein by reference. Item 7.
