         This Amendment No. 1 to Schedule 13D is being filed on behalf of the
undersigned to amend the Schedule 13D (the "Schedule 13D") which was originally
filed on February 3, 1999. Unless otherwise indicated, all capitalized terms
used herein but not defined herein shall have the same meaning as set forth in
the Schedule 13D. This Amendment is being filed pursuant to Rule 13d-2 of the
General Rules and Regulations under the Securities and Exchange Act of 1934 as
amended. Only those items reported herein are amended. All other items remain
unchanged.

ITEM 5.INTEREST IN SECURITIES OF THE ISSUER.

                  (a) As a result of the transactions referred to under Item 6
below, the Bank is now the holder of 7,837,332 Common Shares.

                  (b) As a result of the transaction referred to under Item 6
below, the Bank is the sole holder of the power to vote or direct the vote and
the sole holder of the power to dispose or direct the disposition of the Common
Shares. The persons on whose behalf the bank acts may revoke this power at any
time by notice to the Bank.

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

         On June 21, 1999 the Bank and Advantix (now known as Tickets.com, Inc.)
("Tickets.com") entered into the First Amendment to Agreement (the "First
Amendment"), dated that date. The First Amendment amended the Purchase Agreement
in several material respects. First, notwithstanding that the consummation of
the transactions contemplated by the Purchase Agreement was to have occurred on
or prior to May 15, 1999, Tickets.com agreed to purchase all of the Preferred
Shares within three business days after the Issuer executed a definitive
Agreement and Plan of Merger (the "Merger Agreement") with Tickets.com pursuant
to which a subsidiary of Tickets.com would merge with and into the Issuer (the
"Merger"). Second, Tickets.com agreed to pay 170.081 shares of Tickets.com
common stock or $435.00 for each outstanding Preferred Share, at the option of
the holder of each of the Preferred Shares. Third, the parties agreed that
Tickets.com would purchase the Common Shares as part of the Merger under the
Merger Agreement and not as a separate transaction under the Purchase Agreement.
The obligation of Tickets.com to purchase the Preferred Shares was subject to
the resignation by Jacqueline E. Soechtig as an officer and director of the
Issuer and Ms. Soechtig's general release of the Issuer and Tickets.com. All
other provisions contained in the Purchase Agreement remained in full force and
effect.

         On June 28, 1999, the Bank sold and delivered the Preferred Shares to
Tickets.com and Tickets.com paid $754,290 and issued 674,541 shares of its
common stock pursuant to the First Amendment.

         As a result of the transactions referred to above, the Bank's holding
of the Issuer's shares has been reduced to 7,837,332 Common Shares. The shares
represent 51.2% of the Issuer's Common Stock as reported in the Issuer's
Quarterly Report on Form 10-QSB for the quarter ended September 30, 1998 (the
most recent quarterly report filed by the Issuer). The Bank is the record holder
of the Common Shares and entered into the Purchase Agreement on instructions

from the holders of the Underlying Shares; the power to vote the Common Shares
and the power to dispose of the Common Shares (to the extent such power may be
exercised at all, after giving effect to the transactions contemplated by the
Merger Agreement) remain with the approximately 60 independent holders of the
Common Shares, each of whom is an Austrian national.

         On June 21, 1999 the Bank and the Issuer entered into a Settlement and
Release Agreement (the "Settlement Agreement") settling the legal action
commenced on February 8, 1999 by the Bank against the Issuer and its directors
in the Circuit Court of Pinellas County, Florida. Thereafter, the Issuer and its
directors interposed certain defenses and counterclaims against the Bank in that
case. Pursuant to the Settlement Agreement, the Issuer delivered inducement
letters from each of the Issuer's directors containing mutual releases pursuant
to which each of the Bank, the Issuer and Tickets.com released the directors and
each of the directors generally released the Bank, the Issuer and Tickets.com
from claims, liabilities and obligations. The inducement letters provided for
the resignation of the three directors and, in the case of Jacqueline Soechtig,
the termination of her employment as well. The parties agreed to dismiss the
action with prejudice.

         The Settlement Agreement also provided that, as a material condition to
the Bank's obligations set forth therein, immediately after approving the
transactions contemplated by the Merger Agreement and recommending that the
Issuer's shareholders accept the Merger and adopt and approve the Merger
Agreement, the Issuer's Board of Directors would (i) appoint David A. Riley as
the Issuer's President and Chief Executive Officer, (ii) fill two existing
vacancies with David A. Riley and Steven H. Noble III and (iii) then resign from
the Issuer's Board of Directors. The three individuals who comprised the
Issuer's board immediately prior to June 21, 1999 so acted, and Mr. Riley and
Mr. Noble, having been so appointed, comprise the Issuer's Board of Directors,
subject to the Issuer's compliance with the applicable rules and regulations of
the Securities and Exchange Commission.

         Clifford Soechtig, the husband of Jacqueline Soechtig also provided an
inducement letter containing a mutual release and terminating his employment
with the Issuer.
