Item 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

Item 6 is hereby amended by adding at the end thereof the following:

     The Issuer declared a dividend with a record date of December 1, 2000 pursuant to which each holder of the Stock received a warrant to purchase one-half of a share of the Stock for each share of the Stock owned on the record date (the "Dividend Warrants"). The Dividend Warrants were dated as of December 19, 2000, but will not be exercisable until February 27, 2002 (the "Benchmark Date"), the date that is one year after the effective date of the Merger. The exercise price for the Dividend Warrants has not been determined. When they become exercisable, the Dividend Warrants will have an exercise price per share of the Stock equal to 1.25 times the lesser of (i) $1.4815, and (ii) the lowest average closing price of the Stock over any consecutive 20 calendar days during the 90 calendar days after the Benchmark Date. If the amount in clause (ii) cannot be determined from the publication by the American Stock Exchange or the National Quotations Bureau LLP, the lowest average closing price for such period will be determined in good faith by the Issuer's Board of Directors. The description of the warrants contained herein is qualified in its entirety by reference to a copy of the Warrant Agreement covering the Dividend Warrants, which Warrant Agreement is hereby incorporated herein by reference in its entirety. A copy of the Warrant Agreement is attached hereto as Exhibit 99.9.

     FW PowerBrief is a party to a Preferred Stock Purchase Agreement dated March 27, 2001 by and among the Issuer, FW PowerBrief, and certain other persons and entities (the "Preferred Stock Purchase Agreement"). In connection with the Preferred Stock Purchase Agreement, FW PowerBrief also entered into a registration rights agreement (the "Registration Rights Agreement"), a voting agreement (the "Voting Agreement"), and an indemnification agreement (the "Indemnification Agreement"). The descriptions contained herein of the Preferred Stock Purchase Agreement, the Registration Rights Agreement, the Voting Agreement, and the Indemnification Agreement and the certificate of designation relating to the Series A Stock are not, and do not purport to be, complete and are qualified in their entirety by reference to such agreements which are attached hereto as Exhibits 99.10 through 99.14 and are fully incorporated herein by this reference.

     Preferred Stock Purchase Agreement

     As described under Item 5(c) above, FW PowerBrief purchased shares of the Series A Stock from the Issuer on March 27, 2001 pursuant to the Preferred Stock Purchase Agreement. The Series A Stock purchased by FW PowerBrief is currently convertible into shares of the Stock at a rate of ten shares of the Stock for each share of the Series A Stock, based on a liquidation preference of $1.12 per share and a conversion price of $.112 per share, which is subject to adjustment as set forth in the Certificate of Designation and Determination of Rights and Preferences of the Series A Stock (the "Certificate of Designation").

     Certificate of Designation

     The Certificate of Designation provides the holders of the Series A Stock the number of votes equal to the number of whole shares of the Stock into which a share of the Series A Stock could be converted at the record date for the determination of shareholders entitled to vote on the relevant matter or, if no record date is established, the date such vote is taken or any written consent of shareholders is solicited. Each holder of the Series A Stock has full voting rights and powers equal to the voting rights and powers of the holders of the Stock, and except as expressly provided in the Certificate of Designation, the holders of the Series A Stock and the holders of the Stock shall vote together and not as separate classes.  The holders of the Series A Stock, voting as a separate series, are entitled to elect two directors.

     The Series A Stock is convertible into shares of the Stock at any time or from time to time at a ratio determined by dividing the liquidation value of the Series A Stock (including the stated liquidation preference and accrued but unpaid dividends) by the conversion price. The initial liquidation value of the Series A Stock is $1.12 per share, while the initial conversion price is $0.112 per share, in both cases subject to adjustment as provided in the Certificate of Designation. The holders of the Series A Stock are entitled to receive cumulative cash dividends at a rate per annum of $.0896 per share, subject to adjustment. At the option of the Issuer, dividends on the Series A Stock may be paid, instead of in cash, in whole or in part, on declaration of the Board of Directors, in additional shares of the Series A Stock.

     Registration Rights Agreement

     The Registration Rights Agreement entitles holders of the Series A Stock, shares of the Stock issuable or issued upon conversion of the Series A Stock, and other shares of the Stock issued as a dividend or other distribution with respect to, or in exchange for or in replacement of the Series A Stock or shares of common stock issuable upon conversion thereof, certain rights with respect to the registration of such shares under the Securities Act of 1933, as amended (the "Securities Act"). The Registration Rights Agreement requires the Company to use its best efforts to effect a registration to permit the sale of Registrable Securities upon written demand from holders of at least 20% of the Registrable Securities then outstanding. The Company is required to use its best efforts to cause such Registration Statement to become effect as soon as reasonably practicable and to keep such Registration Statement continuously effective unless and until Rule 144 under the Securities Act would permit the public sale of all of the Registrable Securities during a three-month period without registration.

     Voting Agreement

     FW PowerBrief, FW Investors, FW Investors II, and the Issuer are parties to the Voting Agreement. Pursuant to the Voting Agreement, FW PowerBrief, FW Investors and FW Investors II have agreed to vote or to act with respect to their shares so as to elect (a) a certain number of members of the Issuer's board of directors designated by Keystone, Inc. (an entity associated with the Reporting Persons) or its affiliates (the "Keystone Directors"), one such member to be Scott Hancock ("Hancock"), with the number of Keystone Directors to be determined by multiplying the total number of members of the Issuer's Board of Directors by the quotient obtained by dividing (i) the total number of shares of Series A Stock and shares of the Stock held by Keystone and the Reporting Persons on an as-converted basis, by (ii) the total number of the Issuer's shares of Series A Stock and shares of the Stock on an as-converted basis then actually issued and outstanding; provided that the number of such directors shall be no less than one; (b) one member of the Issuer's board of directors designated by the Issuer's senior management team, and (c) one independent member of the Issuer's board of directors unanimously designated by the members of the board designated pursuant to (a) and (b).  Hancock is currently a member of the Issuer's Board of Directors, having served in that capacity as a representative of certain of the Reporting Persons since December of 1997.

     Indemnification Agreement

     FW PowerBrief, the Issuer, and Hancock are parties to the Indemnification Agreement, which provides that the Issuer shall indemnify both Hancock and FW PowerBrief (each an "Indemnitee" and together the "Indemnitees"), to the fullest extent permitted by law with respect to any threatened, pending or completed action, suit or proceeding, including actions by or in the right of the Issuer, arising (i) by reason of the fact that either of the Indemnitees is or was a director, officer or shareholder of the Issuer, (ii) by reason of any action or inaction on the part of either of the Indemnitees while a director, officer, controlling person, shareholder, fiduciary, employee or agent of the Issuer, or (iii) by reason of the fact that either Indemnitee is or was may be deemed to be serving at the request of the Issuer as a director, officer, agent or in a similar capacity with respect to another corporation or business enterprise.
