            This Amendment No. 3 is filed in accordance with Rule 13d-2 of the
Securities Exchange Act of 1934, as amended, by the Reporting Person and refers
only to information which has materially changed since the filing of Amendment
No. 2 to Schedule 13D by the Reporting Person on November 12, 2003. The items
identified below, or the particular paragraphs of such items which are

Capitalized terms not otherwise defined herein have the meanings ascribed to
them in the original Schedule 13D.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

            Effective as of March 26, 2003, Federal Partners, L.P. ("Federal
Partners") purchased from the Issuer in a private placement transaction a 4.95%
Subordinated Note due 2006 in the principal amount of $3,050,000 (the "Note")
with interest payable quarterly and 3,150,002 shares of Common Stock (the "March
2003 Shares") for an aggregate purchase price of $3,050,000 pursuant to a
Securities Purchase Agreement (the "March 2003 Purchase Agreement").

            In connection with this private placement, the Issuer agreed
pursuant to a Registration Rights Agreement (the "March 2003 Registration Rights
Agreement") to file a Registration Statement with the SEC with respect to the
March 2003 Shares and certain other shares of Common Stock issued in connection
with this private placement.

            Effective as of November 12, 2003, Federal Partners purchased from
the Issuer in a private placement transaction an additional 3,125,000 shares of
Common Stock (the "November 2003 Shares" and together with the March 2003
Shares, the "Shares") for an aggregate purchase price of $2,500,000 pursuant to
a Stock Purchase Agreement (the "November 2003 Stock Purchase Agreement").

            In connection with this private placement, the Issuer agreed
pursuant to a Registration Rights Agreement (the "November 2003 Registration
Rights Agreement") to file a Registration Statement with the SEC with respect to
the November 2003 Shares.

            Effective as of July 27, 2005, Federal Partners purchased from the
Issuer in a private placement transaction an additional 1,290,323 shares of
Common Stock (the "July 2005 Shares" and together with the "November 2003
Shares" and the March 2003 Shares, the "Shares") for an aggregate purchase price
of $2,000,000 pursuant to a Stock Purchase Agreement (the "July 2005 Stock
Purchase Agreement").

            In connection with this private placement, the Issuer agreed
pursuant to a Registration Rights Agreement (the "July 2005 Registration Rights
Agreement") to file a Registration Statement with the SEC with respect to the
July 2005 Shares.

            In addition, on July 27, 2005, the Issuer and Federal Partners
amended the Note (the "Amended Note") to extend the maturity date from March 31,
2006 to March 31, 2008 in exchange for the payment by the Issuer of $61,000 to
Federal Partners.

            Federal Partners is a limited partnership, the general partner of
which is Ninth Floor Corporation. The Reporting Person provides management and
administrative services to Federal Partners. The purchase price for the Shares
and the Note was provided by funds available for investment by accounts for
which the Reporting Person provides management and administrative services.



ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

            (a) The 8,118,725 shares of Common Stock beneficially owned by the
Reporting Person, 7,565,325 of which are held of record by Federal Partners and
the remainder of which are held of record by the Reporting Person for the
benefit of accounts for which the Reporting Person provides management and
administrative services, constitute approximately 14.0% of the outstanding
shares of the Common Stock, computed in accordance with the provisions of SEC
Rule 13d-3(d)(1) (based upon an aggregate of 57,932,000 outstanding shares of
the Common Stock as of April 27, 2005, as disclosed in the Issuer's Quarterly
Report on Form 10-Q for the quarter ended March 31, 2005).

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
        SECURITIES OF THE ISSUER

            Except for the March 2003 Securities Purchase Agreement, the Amended
Note, the March 2003 Registration Rights Agreement, the November 2003 Stock
Purchase Agreement and the November 2003 Registration Rights Agreement, the July
2005 Stock Purchase Agreement and the July 2005 Registration Rights Agreement
neither the Reporting Person nor (to the best knowledge of the Reporting Person)
any of its executive officers or directors has any contract, arrangement,
understanding or relationship (legal or otherwise) with any person with respect
to any securities of the Issuer, including but not limited to the transfer or
voting of any of such securities, finder's fees, joint ventures, loan or option
agreements, puts or calls, guarantees of profits, division of profits or losses,
or the giving or withholding of proxies.

                                    SIGNATURE

            After reasonable inquiry and to the best of my knowledge and belief,
