Other Events. On February 10, 1997, the Board of Directors of Mine Safety Appliances Company (the "Company") approved the adoption of a shareholder rights plan. The plan is intended to promote continuity and stability, deter coercive or partial offers which will not provide fair value to all shareholders, and enhance the Board's ability to represent all shareholders and thereby maximize shareholder values. Pursuant to the Rights Agreement entered into between the Company and Norwest Bank Minnesota, N.A., as Rights Agent (the "Rights Agreement"), one right ("Right") will be issued for each share of common stock, no par value per share, of the Company outstanding as of the close of business on February 21, 1997. Each of the Rights will entitle the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock at a price of $225 per one one-thousandth of a share. The Rights generally will not become exercisable unless and until, among other things, any person acquires, after excluding "exempted shares," beneficial ownership of 15% or more of the outstanding stock. The Rights are generally redeemable at $.01 per Right at any time until 10 days following a public announcement that such a 15% or greater position in the Company's common stock has been acquired and will expire, unless earlier redeemed or exchanged, on February 21, 2007. A description of the Rights is set forth in Exhibit B to the Rights Agreement, a copy of which is filed herewith and is incorporated herein by reference. Item 7. Financial Statements and Exhibits.
