                              (Page 7 of 10 Pages)





     WCM is the sole general partner of the Partnership and Partnership-I and,
accordingly, may be deemed to be the indirect beneficial owner (as that term is

general partner of the Partnership and Partnership-I, has the sole power to
direct the voting and disposition of the shares of Common Stock that the
Partnership and Partnership-I beneficially own.

     Messrs. Obus and Landes are the co-managing members of WCM and,
accordingly, each of Messrs. Obus and Landes may be deemed to be the indirect
beneficial owner (as that term is defined under Rule 13d-3 under the Exchange
Act) of the shares of Common Stock that WCM may be deemed to beneficially own.
Each of Messrs. Obus and Landes, as a co-managing member of WCM, shares with the
other the power to direct the voting and disposition of the shares of Common
Stock that WCM may be deemed to beneficially own.

     WCI is the sole investment manager of the Fund and, accordingly, may be

     Beneficial ownership of shares of Common Stock shown on the cover pages of

Wynnefield Group assumes that they have not formed a group for purposes of
Section 13(d)(3) under the Exchange Act, and Rule 13d-5(b)(1) promulgated
thereunder. If the members of the Wynnefield Group were deemed to have formed a
group for purposes of Section 13(d)(3) and Rule 13d-5(b)(1), the group would be
deemed to own beneficially (and may be deemed to have shared voting and
dispositive power over) 705,000 shares of Common Stock, constituting
approximately 4.3% of the outstanding shares of Common Stock (the percentage of
shares owned being based upon 16,233,149 shares outstanding on December 10,
2003, as set forth in the Issuer's most recent report on Form 10-Q for the
period ended September 30, 2003, filed with the Commission on January 6, 2004).

     The filing of this Amendment No. 1 and any future amendment by the
Wynnefield Group, and the inclusion of information herein and therein with
respect to Messrs. Obus and Landes, shall not be considered an admission that
any of such persons, for the purpose of Section 13(d) of the Exchange Act, are
the beneficial owners of any shares in which such persons do not have a
pecuniary interest.

     To the best knowledge of the Wynnefield Group, except as described in this
Amendment No. 1, none of the Wynnefield Group, any person in control (ultimately
or otherwise) of the Wynnefield Group, any general partner, executive officer or
director thereof, as applicable, beneficially owns any shares of Common Stock,
and except as set forth in the table below, there


                              (Page 8 of 10 Pages)





have been no transactions in shares of Common Stock affected during the past 60
days, by the Wynnefield Group, any person in control of the Wynnefield Group
(ultimately or otherwise), or any general partner, executive officer or director
thereof, as applicable; provided, however, certain investment banking affiliates
of the Wynnefield Group may beneficially own shares of Common Stock, including
shares that may be held in discretionary or advisory accounts with the
Wynnefield Group; and the Wynnefield Group, directly or in connection with such
discretionary or advisory accounts, may acquire, hold, vote or dispose of Common
Stock, including transactions that may have occurred during the past 60 days.

     The members of the Wynnefield Group listed below have made open market
sales of shares of Common Stock during the past 60 days, as follows:

direct the receipt of dividends from, or the proceeds from the sale of, such
shares of Common Stock.
