Treinen Chairman of the Board of Directors 3 SUPPLEMENT TO PROXY STATEMENT DATED NOVEMBER 11, 1998 This is a Supplement to the Proxy Statement dated November 11, 1998 (the "Proxy Statement"). This Supplement contains additional information for your consideration of Amendment No. 1 to the Merger Agreement. The capitalized terms used in this Supplement and not defined herein shall have the meanings ascribed them in the Proxy Statement. STOCKHOLDER LITIGATION As reported in the August Proxy Statement and the Proxy Supplement to the August Proxy Statement (both of which are attached as Appendices B and C, respectively to the Proxy Statement), three purported stockholder class action lawsuits were filed in the Delaware Court of Chancery challenging the Merger. These lawsuits alleged, among other things, that the directors of SDI violated their fiduciary duties to SDI by failing to obtain sufficient consideration for the Merger and by failing to disclose material information in the Proxy Statement. On November 30, 1998, SDI learned of a fourth purported stockholder class action lawsuit filed in the Delaware Court of Chancery challenging the Merger. The lawsuit, filed by Paul Packer, purportedly on behalf of himself and other stockholders of SDI as of October 15, 1998, is brought against J. Nelson Hoffman, Jack B. Watson, Thomas F. Treinen, Samuel Levin, Donald A. Bendix, John M. Cuthbert, Robert S. Ritchie, and SDI. The lawsuit essentially charges the individual defendants with breaching their fiduciary duties to the public stockholders of SDI by allegedly failing to obtain adequate consideration for the Merger. The Complaint alleges, INTER ALIA, that the terms of the merger are unfair, that the consideration to be paid to the public shareholders of SDI is unfair, inadequate and substantially below the fair market value of the company, that the individual defendants failed to take steps to enhance SDI's value, that they failed to effectively expose the company in the marketplace, and that they are favoring their own interests at the expense of the public stockholders. SDI has just been served with the Complaint and the individual defendants have not yet been served. Management disputes all of plaintiff's material allegations and believes that this lawsuit, like the three previously-filed purported stockholder class action lawsuits, is without merit. As further reported in the Proxy Supplement to the August Proxy Statement, the plaintiffs and defendants agreed in the first three purported class actions to enter into a memorandum of understanding ("MOU"), evidencing the parties' agreement on the material terms of a settlement of the litigation. SDI and its counsel are continuing in discussions with counsel for the plaintiffs in all of these actions and it is possible that the actions will still be settled. Whether or not a settlement is reached, SDI will proceed with the meeting of Stockholders on December 10, 1998 and, if approved, close the transaction soon thereafter. SDI will vigorously defend the actions if they are not settled. Any settlement will be subject to approval by the Delaware Court of Chancery. 4 RECENT DEVELOPMENTS SDI recently announced preliminary unaudited results for the fiscal year and fourth quarter ended October 31, 1998. For the fiscal year, net sales are expected to be approximately $170.5 million, a 21.4% increase over fiscal year 1997. For the fourth quarter, net sales are expected to be approximately $41.3 million, a decrease of 4.4% from the fourth quarter of fiscal year 1997, while earnings before interest, taxes, depreciation and amortization are expected to be greater than earnings before interest, taxes, depreciation and amortization generated in the fourth quarter of fiscal year 1997. Results for the Automotive Products Division for the fourth quarter of fiscal year 1998 were adversely affected by the 54-day United Auto Workers strike at General Motors and continued weakness in the Asian market, resulting in reduced purchases by certain customers. Results for the Aerospace Division increased over the prior year due primarily to sales of a proprietary bomb ejector product and increased demand for products used in commercial satellite launch vehicles. 5 PROXY SPECIAL DEVICES, INCORPORATED Proxy Solicited on Behalf of the Board of Directors The undersigned, revoking all previous proxies, hereby appoints Thomas F.
