The series of Preferred Stock designated and known as "Series H Special Preferred Stock" shall consist of 200,000 shares, par value $.01 per share. Shares of the Special Preferred Stock shall, with respect to rights on liquidation, winding up and dissolution, rank senior to all classes of common stock of the Corporation (including, without limitation, the Common Stock, par value $.004 per share (the "Common Stock")), and each other class of capital stock or series of preferred stock hereafter created which does not expressly provide that it ranks on a parity with the Special Preferred Stock as to rights on liquidation, winding up and dissolution ("Junior Stock"), on a parity with the Series D Preferred Stock, Cumulative Convertible Preferred Stock and each other class of capital stock or series of preferred stock hereafter created which expressly provides that it ranks on a parity with the Special Preferred Stock as to rights on liquidation, winding up and dissolution ("Parity Stock"), and, junior to the Series C Preferred Stock and each other class of capital stock or series of preferred stock hereafter created which has been approved by the holders of the Special Preferred Stock in accordance with Section 4 and which expressly provides that it ranks senior to the Special Preferred Stock as to rights on liquidation, winding up and dissolution ("Senior Stock"). 2. Dividends. (a) The holders of the Special Preferred Stock shall not be entitled to receive any dividends. 3. Liquidation, Dissolution or Winding Up. (a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Special Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders, after and subject to the payment in full of all amounts required to be distributed to the holders of any Senior Stock but before any payment shall be made to the holders of any Junior Stock, and on a parity with any payment to the holders of Parity Stock, an amount equal to $100 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares) (the "Original Liquidation Preference") plus with respect to any date after December 31, 1996, an amount (which amount, collectively with the Original Liquidation Preference, is hereinafter referred to as -2- the "Liquidation Preference") equal to 5% per annum of the Original Liquidation Preference thereof calculated on a daily basis from January 1, 1996 to such date; provided that the maximum Liquidation Preference shall not exceed $30,000,000. If upon any such liquidation, dissolution or winding up of the Corporation the remaining assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Special Preferred Stock the full amount to which they shall be entitled, the holders of Special Preferred Stock shall share ratably in any distribution of the remaining assets and funds of the Corporation in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. (b) After the payment of all preferential amounts required to be paid to the holders of Senior Stock, Parity Stock and Special Preferred Stock upon the dissolution, liquidation or winding up of the Corporation, the holders of shares of Junior Stock then outstanding shall be entitled to receive the remaining assets and funds of the Corporation available for distribution to its stockholders. (c) Written notice of such liquidation, dissolution or winding up, stating a payment date and the place where said payment shall be made, shall be given by mail, postage prepaid, or by telecopier, not less than 20 days prior to the payment date stated therein, to the holders of record of the Special Preferred Stock, such notice to be addressed to each such holder at its address as shown by the records of the Corporation. (d) Whenever the distribution provided for in this Section 3 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors of the Corporation. (e) For the purposes of this Section 3, neither the voluntary sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation nor the consolidation or merger of the Corporation with one or more other corporations shall be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, unless such voluntary sale, conveyance, exchange or transfer shall be in connection with a plan of liquidation, dissolution or winding up of the business of the Corporation. -3- 4. Voting. (a) Except as may be otherwise provided in these terms of the Special Preferred Stock or by law, the Special Preferred Stock shall not be entitled to vote.

For this purpose, without limiting the generality of the foregoing, the authorization or issuance of any series of Preferred Stock with preference or priority over the Special Preferred Stock as to the right to receive amounts distribut-able upon liquidation, dissolution or winding up of the Corporation shall be deemed to affect adversely the Special Preferred Stock, and the authorization or issuance of any series of Preferred Stock on a parity with the Special Preferred Stock as to the right to receive amounts distributable upon liquidation, dissolution or winding up of the Corporation shall be deemed not to affect adversely the Special Preferred Stock. 5. Redemption. (a) At any time and from time to time the Corporation may, at the option of its Board of Directors, redeem the Special Preferred Stock in the manner provided below, in whole or in part, at a redemption price equal to 100% of the Liquidation Preference thereof on the Redemption Date (as defined below). (b) The Corporation shall redeem all outstanding shares of Special Preferred Stock on (x) the date which is 35 days after the occurrence of a Change of Control (as defined below) and, in any event, on (z) March 31, 2007 in each such case in the manner provided below at a redemption price equal to 100% of the Liquidation Preference thereof on the Redemption Date. (c) On March 31 of each year, commencing with March 31, 1997, the Corporation shall redeem at a redemption price equal to 100% of the Liquidation Preference thereof on such Redemption Date an amount (the "Required Redemption Amount") of Special Preferred Stock equal to 50% of the amount, if any, by which the consolidated EBITDA (as defined below) of the Corporation and its subsidiaries exceeds the Threshold Amount set forth below for the immediately preceding year ended on -4- December 31. To the extent the Required Redemption Amount exceeds 50% of the sum (the "Income Limitation") of (i) the consolidated net income of the Corporation and its subsidiaries for the immediately preceding year ended on December 31 (without deducting therefrom any amounts on account of dividends paid or payable on any preferred stock or redemptions of any preferred stock of the Corporation, including, without limitation, the Convertible Preferred Stock, Special Preferred Stock and Series C and D classes of Preferred Stock of the Corporation) plus (ii) amounts attributable to the amortization of goodwill of the Corporation and its subsidiaries for such immediately preceding year, such excess amount shall be carried forward and be considered a Required Redemption Amount for the next succeeding year and for each year thereafter until paid. The Threshold Amount for each year shall be as follows: Year Ended Threshold December 31, Amount 1996......................................... $47.0 million 1997......................................... 53.0 million 1998......................................... 57.5 million 1999......................................... 60.5 million 2000......................................... 63.5 million 2001......................................... 66.5 million 2002......................................... 69.5 million 2003......................................... 72.5 million 2004......................................... 75.5 million 2005......................................... 78.5 million 2006 and thereafter.......................... 81.5 million "EBITDA" means net income plus income taxes, interest expense, depreciation and amoritization. In the event that the Corporation or any subsidiary sells or disposes of any material asset or business ("material" meaning having a value of $250,000 or more), the Threshold Amount for each year thereafter as set forth above shall be reduced by the amount of EBITDA attributable to such asset or business for the four fiscal quarters immediately preceding such sale or disposition. All accounting terms used in this paragraph (c) shall be determined in accordance with generally accepted accounting principles consistently applied as in effect in the United States from time to time. (d) At least 30 days prior to the date fixed for any redemption of Special Preferred Stock (hereinafter referred to as the "Redemption Date"), written notice (the "Redemption Notice") -5- shall be mailed, by first class or registered mail, postage prepaid, to each holder of record of Special Preferred Stock to be redeemed, at its address last shown on the records of the transfer agent of the Special Preferred Stock (or the records of the Corporation, if it serves as its own transfer agent). The Redemption Notice shall state: (1) whether the redemption is pursuant to Section (5)(a), (5)(b)(x), (5)(b)(z) or 5(c) hereof; (2) the redemption price thereof; (3) whether all or less than all the outstanding shares of the Special Preferred Stock redeemable thereunder are to be redeemed and the total number of shares of such Special Preferred Stock being redeemed; (4) the number of shares of Special Preferred Stock held, as of the appropriate record date, by the holder that the Corporation intends to redeem; (5) the date fixed for redemption (the "Redemption Date"); and (6) that the holder is to surrender to the Corporation, at the place or places where certificates for shares of Special Preferred Stock are to be surrendered for redemption, in the manner and at the price designated, his certificate or certificates representing the shares of Special Preferred Stock to be redeemed. (e) Each Holder of Special Preferred Stock shall surrender the certificate or certificates representing such shares of Special Preferred Stock to the Corporation, duly endorsed, in the manner and at the place designated in the Redemption Notice, and on the Redemption Date the full redemption price for such shares shall be payable in cash to the Person whose name appears on such certificate or certificates as the owner thereof, and each surrendered certificate shall be canceled and retired and shall not under any circumstances be reissued. In the event that less than all of the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. (f) Unless the Corporation defaults in the payment in full of the redemption price the holders of such redeemed shares shall cease to have any further rights with respect thereto on -6- the Redemption Date, other than the right to receive the redemption price with respect thereto, without interest. (g) In the event of any redemption of only a part of the then outstanding Special Preferred Stock, the Corporation shall effect such redemption pro rata among the holders thereof based on the number of shares of Special Preferred Stock held by such holders on the date of the Redemption Notice. (h) The occurrence of any of the following events will constitute a "Change of Control" for purposes of this Section 5: (i) any "person" (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than one or more Permitted Holders (as defined below), is or becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act except that for purposes of this clause (i) such person shall be deemed to have "beneficial ownership" of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 30% of the total voting power of the Voting Stock (as defined below) of the Corporation; provided, however, that the Permitted Holders beneficially own (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, in the aggregate a lesser percentage of the total voting power of the Voting Stock of the Corporation than such other person and do not have the right or ability by voting power, contract or otherwise to elect or designate for election a majority of the Board of Directors of the Corporation (for the purposes of this clause (i), a person shall be deemed to beneficially own any Voting Stock of a specified corporation held by another corporation (the "parent corporation"), if such other person is the beneficial owner (as defined in this clause (i) above), directly or indirectly, of more than 30% of the voting power of the Voting Stock of such parent corporation and the Permitted Holders beneficially own (as defined in this clause (i) above), directly or indirectly, in the aggregate a lesser percentage of the voting power of the Voting Stock of such parent corporation and do not have the right or ability by voting power, contract or otherwise to elect or designate for election a majority of the board of directors of such parent corporation); (ii) during any two consecutive 365-day periods, individuals who at the beginning of such period constituted -7- the Board of Directors of the Corporation (together with any new directors whose election by the Board of Directors of the Corporation or whose nomination for election by the shareholders of the Corporation was approved by a vote of 66-2/3% of the directors of the Corporation then still in office who were either directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors of the Corporation then in office; or (iii) the merger or consolidation of the Corporation with or into another Person or the merger of another Person with or into the Corporation, or the sale of all or substantially all the assets of the Corporation to another Person (other than a Person that is controlled by the Permitted Holders), and, in the case of any such merger or consolidation, the securities of the Corporation that are outstanding immediately prior to such transaction and which represent 100% of the aggregate voting power of the Voting Stock of the Corporation are changed into or exchanged for cash, securities or property, unless pursuant to such transaction such securities are changed into or exchanged for, in addition to any other consideration, securities of the surviving corporation that represent immediately after such transaction, at least a majority of the aggregate voting power of the Voting Stock of the surviving corporation and have the immediate right to appoint a majority of the Board of Directors of the surviving corporation.
