This Amendment No. 2 (this "Amendment") amends the statement on Schedule 13G
filed on May 7, 2007, as amended by Amendment No. 1 filed on November 28, 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

     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) 290,040 Shares owned by D.B. Zwirn Special Opportunities Fund, L.P. and (ii)
426,960 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 4.94% of the outstanding Shares, (ii) D.B. Zwirn Special
Opportunities Fund, Ltd. owns approximately 7.28% 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 12.22% 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)
