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 (b) Percent of Class: 11.28% (c) Number of shares as to which each person has: (i) sole power to vote or to direct the vote: 0 (ii) shared power to vote or to direct the vote: 142,400 Page 11 of 17 (iii) sole power to dispose or to direct the disposition of: 0 (iv) shared power to dispose or to direct the disposition of: 142,400 Item 5.
