Item 4.  Ownership

This Amendment No. 2 is filed pursuant to Section 240.13d-2(b) of the Securities
and Exchange Act of 1934. The statement on this amended Schedule 13G relates to
an aggregate total of 142,400 shares of the outstanding common shares of the
issuer, Aerocentury Corp., beneficially owned as of December 31, 2002,
representing 11.28% of the class (the "Shares").

On January 30, 1999, PAL-BRO PARTNERS, LLC ("Pal-Bro"), a registered
broker-dealer and American Stock Exchange, Inc.


                                  Page 10 of 17

specialist member organization, acquired a position in the Shares in excess of
5% of the issuer's outstanding common shares in the normal course of its duty to
maintain a fair and orderly market as the designated specialist in the common
stock of Aerocentury Corp.

On January 2, 2002, Pal-Bro transferred its entire specialist business,
including the Shares, to a subsidiary in which Pal-Bro has a minority interest,
HBH Specialists LLC ("HBH"). HBH acquired the Shares as Pal-Bro's
successor-in-interest to Pal-Bro's specialist security positions. Subsequent to
the transfer, Pal-Bro ceased engaging in business as a broker-dealer.

All persons other than HBH identified on this Schedule 13G,represent, as of
January 2, 2002, a parent holding company or a control person of HBH in
accordance with 17 CFR 240.13d-1(b)(1)(ii)(G)(collectively, the "Control
Persons"). Parent holding companies that do not have voting or dispositive power
over the Shares pursuant to agreement are not identified herein.

Only Pal-Bro, and its successor-in-interest, HBH, have held the Shares since
their acquisition. Some or all of the Control Persons of HBH who are identified
in this Schedule may have shared or share with HBH the power to vote, direct the
vote, dispose, or direct the disposition of, the Shares, during some or all of
the reporting period.

Pal-Bro, HBH and the Control Persons (which includes Pal-Bro effective on
January 2, 2002) are of the view that they are not acting as a "group" for
purposes of Section 13(d) or 13(g) under the 1934 Act and that they are not
otherwise required to attribute to each other the "beneficial ownership" of the
Shares held by Pal-Bro, and then by HBH as Pal-Bro's successor-in-interest.

Neither Pal-Bro's nor HBH's position in the Shares has changed by 5% or more
from the position held by Pal-Bro on January 30, 1999. Neither HBH nor Pal-Bro
has made a Section 16(b) filing under the Securities & Exchange Act pursuant to
the exemption set forth in Section 16(d).

(a)   Amount Beneficially Owned:

      142,400 shares as of December 31, 2002
