This Amendment No. 1 (this "Amendment") amends the statement on Schedule 13G
filed on September 27, 2006 (as amended, the "Schedule 13G") with respect to
shares of Common Stock, par value $0.01 per share (the "Shares") of Community
Bankers Acquisition Corp., 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) 354,353 Shares owned by D.B. Zwirn Special Opportunities Fund, L.P. and
(ii) 607,056 Shares owned by D.B. Zwirn Special Opportunities Fund, Ltd. (each
entity referred to in (i) and (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 filed on August
14, 2007 for the quarterly period ended June 30, 2007, there were 9,375,000
Shares outstanding as of August 6, 2007. Therefore, (i) D.B. Zwirn Special
Opportunities Fund, L.P. owns approximately 3.78% of the outstanding Shares,
(ii) D.B. Zwirn Special Opportunities Fund, Ltd. owns approximately 6.48% 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 10.26% 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
