By: _______________________________ Name:_______________________________ Title:______________________________ SUNTRUST BANK By: _______________________________ Name:_______________________________ Title:______________________________ 473363.1 EXHIBIT A ISOLYSER COMPANY, INC. SUMMARY OF SHAREHOLDER PROTECTION RIGHTS PLAN AS AMENDED BY THE FIRST AMENDMENT THERETO DISTRIBUTION AND TRANSFER OF RIGHTS; RIGHTS CERTIFICATES: The Board has declared a dividend of one Right for each share of Common Stock outstanding on December 31, 1996. Prior to the Separation Time referred to below, the Rights will be evidenced by and trade with the Common Stock and will not be exercisable. After the Separation Time, the Company will mail Rights Certificates to shareholders and the Rights will become transferable apart from the Common Stock. SEPARATION TIME: Rights will separate from the Common Stock and become exercisable following the earlier of (i) the date of the Flip-in Trigger referred to below or (ii) the tenth business day (or such later day as the Board may decide) after any person commences a tender offer that would result in such person holding a total of 15% or more of the Common Stock. EXERCISE OF RIGHTS: After the Separation Time, each Right will entitle the holder to purchase, for an Exercise Price of $60.00, Participating Preferred Stock designed to have economic and voting terms similar to those of one share of Common Stock. "FLIP-IN" TRIGGER: Upon announcement that any person has acquired 15% or more of the outstanding Common Stock, then: (i) Rights owned by the person acquiring such stock (an "Acquiring Person") or transferees thereof will automatically become void; and (ii) each other Right will automatically become a right to buy, for the Exercise Price, that number of shares of Common Stock or Participating Preferred Stock having a market value of twice the Exercise Price. EXCHANGE OPTION: If any person acquires between 15% and 50% of the outstanding Common Stock, the Board may, in lieu of allowing Rights to be exercised, require each outstanding Right to be exchanged for one share of Common Stock or Participating Preferred Stock designed to have economic and voting terms similar to those of one share of Common Stock. "FLIP-OVER" TRIGGER: After an Acquiring Person has become such, the Company may not consolidate or merge with, or sell 50% or more of its assets or earning power to, any person (a "Flip-Over Transaction or Event") if at the time of such merger or sale (or agreement to do any of the foregoing) the Acquiring Person controls the Board of Directors and, in the case of a merger, will receive different treatment than all other shareholders unless proper provision is made so that each Right would thereafter become a right to buy, for the Exercise Price, that number of shares of common stock of such other person having a market value of twice the Exercise Price. REDEMPTION: The Rights may be redeemed by the Board, at any time, until a "Flip-in" Trigger has occurred, at a Redemption Price of $0.001 per Right, subject to the restriction described below. 473363.1 POWER TO AMEND: The Board may amend the Plan in any respect until a "Flip-in" Trigger has occurred, subject to the restriction described below. Thereafter, the Board may amend the Plan in any respect not materially adverse to Rights holders generally. RESTRICTION ON REDEMPTION AND AMENDMENTS: The right of the Board to redeem the rights or amend the Plan is restricted in the event of certain circumstances designed to address a situation where a potential "raider" has obtained control of the Board through the election or appointment of non-incumbent directors. These restrictions generally prohibit redemptions or amendments facilitating a transaction with an Acquiring Person for one year or longer following obtaining control of the Board. EXPIRATION: The Rights will expire no later than ten years from the date of their issuance. 473363.1 2 479978.1
