This Amendment No. 1 (this "Amendment") amends the statement on Schedule 13G
filed on May 7, 2007 (as amended, the "Schedule 13G") with respect to shares of
Common Stock, par value $0.0001 per share (the "Shares") of Fortissimo
Acquisition Corp., a Delaware corporation (the "Company"). Capitalized terms
used herein and not otherwise defined in this Amendment have the meanings set
forth in the Schedule 13G. This Amendment amends and restates Item 4 in its
entirety as set forth below.

Item 4.     Ownership

(a)  Amount Beneficially Owned

            As of the date of this filing, D.B. Zwirn & Co., L.P., DBZ GP, LLC,
Zwirn Holdings, LLC, and Daniel B. Zwirn may each be deemed the beneficial owner
of (i) 290,460 Shares owned by D.B. Zwirn Special Opportunities Fund, L.P. and
(ii) 427,540 Shares owned by D.B. Zwirn Special Opportunities Fund, Ltd. (each
entity referred to in (i) through (ii) is herein referred to as a "Fund" and,
collectively, as the "Funds").

            D.B. Zwirn & Co., L.P. is the manager of each of the Funds, and
consequently has voting control and investment discretion over the Shares held
by each of the Funds. Daniel B. Zwirn is the managing member of and thereby
controls Zwirn Holdings, LLC, which in turn is the managing member of and
thereby controls DBZ GP, LLC, which in turn is the general partner of and
thereby controls D.B. Zwirn & Co., L.P. The foregoing should not be construed in
and of itself as an admission by any Reporting Person as to beneficial ownership
of Shares owned by another Reporting Person. In addition, each of D.B. Zwirn &
Co., L.P., DBZ GP, LLC, Zwirn Holdings, LLC, and Daniel B. Zwirn disclaims
beneficial ownership of the Shares held by the Funds.


(b)  Percent of Class

            Based upon the Issuer's Quarterly Report on Form 10-Q for the
quarterly period ended September 30, 2007, there were 5,868,334 Shares
outstanding as of November 14, 2007. Therefore, (i) D.B. Zwirn Special
Opportunities Fund, L.P. owns approximately 4.95% of the outstanding Shares,
(ii) D.B. Zwirn Special Opportunities Fund, Ltd. owns approximately 7.29% of the
outstanding Shares and (iii) each of D.B. Zwirn & Co., L.P., DBZ GP, LLC, Zwirn
Holdings, LLC, and Daniel B. Zwirn may be deemed to beneficially own 12.24% of
the outstanding Shares. The foregoing should not be construed in and of itself
as an admission by any Reporting Person as to beneficial ownership of Shares
owned by another Reporting Person.

(c) Number of shares as to which such person has:

            (i)   Sole power to vote or to direct the vote:

                  See Item 4(a)

            (ii)  Shared power to vote or to direct the vote

                  See Item 4(a)

            (iii) Sole power to dispose or to direct the disposition of

            (iv)  Shared power to dispose or to direct the disposition of
