This Amendment No. 1 (this "Amendment") amends the statement on Schedule 13G
filed on November 26, 2007 (as amended, the "Schedule 13G") with respect to the
shares of Common Stock, par value $0.001 per share (the "Common Stock") of
HD Partners Acquistion Corporation, a Delaware corporation (the "Issuer").
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) 917,462 shares of Common Stock owned by D.B. Zwirn Opportunities Fund,
L.P. and (ii) 1,424,168 shares of Common Stock 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 the Funds, and consequently
has voting control and investment discretion over the shares of Common Stock
held by 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 of Common Stock 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 of Common Stock held by the Funds.


(b)  Percent of Class

            Based upon the Issuer's Definitive Proxy Statement on Schedule 14A
filed on December 24, 2007, the total number of outstanding shares of Common
Stock as of December 24, 2007 was 23,437,500. Therefore, (i) D.B. Zwirn Special
Opportunities Fund, L.P. owns approximately 3.91% of the outstanding shares of
Common Stock, (ii) D.B. Zwirn Special Opportunities Fund, Ltd. owns
approximately 6.08% of the outstanding shares of Common Stock 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 approximately 9.99% of the outstanding shares of
Common Stock. The foregoing should not be construed in and of itself as an
admission by any Reporting Person as to beneficial ownership of shares of Common
Stock 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

                       See Item 4(a)
