The closing of the transaction contemplated by the Letter Agreement (the "Closing") is expected to occur on or about August 28, 2001, and is subject only to payment of the purchase price for the Shares and delivery of the Shares at the Closing. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5 is hereby amended and restated in its entirety: (a) As of the Closing, Rugby may be deemed to beneficially own 5,755,940 shares of the Stock, which based on calculations made in accordance with Rule 13d-3 promulgated under the Exchange Act and, to the best of the Reporting Persons' knowledge, there being 19,947,891 (2) shares of Common Stock outstanding at such time, represents 28.9% of the issued and outstanding shares of the Common Stock of the Issuer. As of the Closing, RMC may be deemed to beneficially own 5,755,940 shares of the Stock, which based on calculations made in accordance with Rule 13d-3 promulgated under the Exchange Act and there being 19,947,891 (2) shares of Common Stock outstanding at such time, represents 28.9% of the issued and outstanding shares of the Common Stock of the Issuer. None of the executive officers and directors of either of the Reporting Persons beneficially owns any Common Stock.

(d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock. (e) Not Applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. On August 20, 2001, the Issuer's Board of Directors (the "Board") authorized the Stock Repurchase Program pursuant to which the Issuer is authorized to purchase up to an aggregate of $15 million of currently issued and outstanding Common Stock. On August 20, 2001, pursuant to the Letter Agreement between the Issuer and Rugby, Rugby agreed to sell the Shares to the Issuer as part of the Issuer's Stock Repurchase Program at a price of $5.99 per share, which was the closing price of the Issuer's Common Stock on the New York Stock Exchange on that date. The aggregate consideration for the Shares to be paid to Rugby by the Issuer represents Rugby's PRO RATA portion of the aggregate dollar amount of the Stock Repurchase Program. The Closing is expected to occur on or about August 28, 2001, and is subject only to payment of the purchase price for the Shares and delivery of the Shares at the Closing. As previously described in Amendment No. 1, pursuant to the Registration Rights Agreement, dated December 16, 1999, between Rugby and the Issuer (the "Registration Rights Agreement"), Rugby is entitled to designate for nomination to the Board three directors, two directors and one director so long as Rugby and its affiliates hold in the aggregate 30%, 20% and 10%, respectively, of the then outstanding Common Stock. Pursuant to the Letter Agreement, Rugby and the Issuer agreed that, if solely as a result of the sale of the Shares, shares of Common Stock beneficially owned by Rugby and its affiliates in the aggregate at any time would constitute less than 30% of the Issuer's outstanding stock (such new ownership percentage, as it may increase from time to time as a result of the Issuer's repurchase of Common Stock pursuant to the Stock Repurchase Program, the "New Percentage"), the Registration Rights Agreement would be deemed to be amended so that Rugby would maintain its right to designate for nomination three directors to be elected to the Board, so long as the Common Stock held by Rugby and its affiliates in the aggregate constitutes at least the New Percentage of the then outstanding Common Stock. The foregoing summary of the Letter Agreement is not intended to be complete and is qualified in its entirety by reference to Exhibit 1 which is attached hereto and incorporated herein by reference.
