                                  SCHEDULE 13D

INTRODUCTION.

         Blackhawk Investors II, L.L.C., a Delaware limited liability company
("Blackhawk II"), Blackhawk Investors, L.L.C., a Delaware limited liability
company in liquidation ("Blackhawk I"), Blackhawk Capital Partners, a Texas
general partnership ("BCP"), Somerset Capital Partners, a New York general
partnership ("SCP"), Steven A. Webster, a natural person ("Webster"), William R.
Ziegler, a natural person ("Ziegler") and Thomas H. O'Neill, Jr., a natural
person ("O'Neill"; O'Neill, Ziegler, Webster, BCP, Blackhawk I and Blackhawk II
being sometimes hereinafter individually referred to as an "Initial Reporting
Person" and collectively as the "Initial Reporting Persons") are signatories to
a certain Schedule 13D which was jointly filed with the Securities and Exchange
Commission (the "Commission") on May 12, 2003 by the Initial Reporting Persons
(the "Initial Group Schedule 13D Filing") because (i) such persons may have been
deemed to constitute a "group" within the meaning of Rule 13d-5(b)(1)
promulgated pursuant to the Securities Exchange Act of 1934, as amended (the
"Exchange Act") by virtue of the fact that they may have acted in concert in
connection with their acquisition of certain securities of the Company (as
hereinafter defined), pursuant to the terms and conditions of a certain
Securities Purchase and Exchange Agreement dated as of May 2, 2003 among the
Initial Reporting Persons, the Company and certain other persons signatory
thereto (the "2003 Securities Purchase Agreement"), (ii) due to certain
affiliations and relationships among the Initial Reporting Persons, some of the
Initial Reporting Persons may be deemed to own beneficially the same securities
acquired from the Company by certain other Initial Reporting Persons, and (iii)
most of the Initial Reporting Persons are parties to a certain Shareholders
Agreement dated as of May 2, 2003 among such Initial Reporting Persons on the
one hand, an unaffiliated third party shareholder on the other hand and the
Company (the "Shareholders Agreement").

         The reporting persons named in Item 2 below (hereinafter sometimes
individually referred to as a "Reporting Person" and collectively as the
"Reporting Persons") are hereby jointly filing this Amendment No. 1 to the
Initial Group Schedule 13D Filing (hereinafter sometimes referred to as this
"Amended Group Schedule 13D Filing") to disclose: (i) the acquisition of certain
shares of newly authorized Series A Senior Convertible Preferred Stock, par
value $10.00 per share, of the Company (the "Series A Preferred Stock") by
certain of the Initial Reporting Persons and two new Reporting Persons that are
affiliates of Webster, pursuant to the terms and conditions of a certain
Securities Purchase Agreement dated as of November 30, 2004 among the Company,
most of the Reporting Persons, and certain other persons signatory thereto (the
"2004 Securities Purchase Agreement"); and (ii) that effective as of December 8,
2003, Blackhawk I ceased to own beneficially any shares of Common Stock of the
Company and therefore is no longer a Reporting Person.

         In accordance with Rule 13d-1(f) promulgated pursuant to the Exchange
Act, the Reporting Persons named in Item 2 below have executed a written
agreement relating to the joint filing of this Amended Group Schedule 13D Filing
(the "Group Filing Agreement"), a copy of which is attached hereto as Exhibit
IX. A copy of the 2004 Securities Purchase Agreement is

Stock will rank senior to all other capital stock of the Company in liquidation.
In liquidation, each share of Series A Preferred Stock will be entitled to
receive (i) $300.00 per share, (ii) any accrued, but unpaid dividends, and (iii)
a pro rata share of the remaining proceeds available for distribution to holders
of the Company's Common Stock on an "as-converted" basis.

         Pursuant to the terms of the Certificate of Designation of Series A
Preferred Stock, each share of Series A Preferred Stock entitles the holder
thereof to vote with the holders of the Common Stock on all matters on an "as
converted basis." In addition, the consent of the holders of a majority of the
Series A Preferred Stock is required for any action which: (i) amends the
preferences, rights or privileges of the Series A Preferred Stock or materially
affects the holders of the Series A Preferred Stock, as a class, in an adverse
manner; (ii) amends the Company's certificate of incorporation; (iii) creates
any class or series of the Company's capital stock on parity with or having
preference over the Series A Preferred Stock; (iv) authorizes the Company's
liquidation, a merger in which the Company is not the surviving entity, the
Company's recapitalization, or a sale or transfer of all or substantially all of
the Company's assets; and (v) certain other corporate actions.

                              Page 14 of 31 Pages


         The Certificate of Designation further provides that (i) if the Company
issues Common Stock or any type of securities giving the holders thereof the
right to purchase Common Stock at a price below the conversion price of the
Series A Preferred Stock, the numbers, rights and privileges of the shares of
Common Stock into which the Series A Preferred Stock shall be convertible shall
be increased, decreased or changed in like manner as if such shares of Common
Stock had been issued and outstanding, fully paid and non-assessable at the time
of such occurrence, and (ii) the shares of Series A Preferred Stock will be
automatically converted into shares of Common Stock at any time the Company
closes an underwritten public offering at a price per share of Common Stock of
at least $1.20, with net proceeds to the Company or the selling shareholders of
at least $20,000,000.

         Holders of the Series A Preferred Stock are entitled to require the
Company to redeem their shares of Series A Preferred Stock, if not previously
converted, at any time after October 31, 2009, for the original purchase price
of $300.00 per share, plus any accrued but unpaid dividends. At any time after
October 31, 2011, the Company may redeem, upon not less than 90 days prior
notice, the then outstanding shares of Series A Preferred Stock for a payment
equal to the original purchase price of $300.00 per share, plus any accrued but
unpaid dividends.

         Each holder of Series A Preferred Stock has a preemptive right to
purchase any new equity securities offered for sale by the Company. Each such
holder's right is limited to a pro rata share of the securities offered, based
upon such holder's pro rata ownership of Common Stock, and assuming that all
shares of Series A Preferred Stock had been converted to Common Stock as of the
time of the proposed offering.

         The Certificate of Designation further provides that the holders of the
Series A Preferred Stock shall be entitled to elect one director to the Board of
Directors of the Company at each annual meeting of the stockholders of the
Company. To date, the holders of the Series A Preferred Stock have not exercised
their contractual right to elect a director to the Board of Directors of the
Company.

         Pursuant to the terms of the 2004 Securities Purchase Agreement, the
purchasers of the Series A Preferred Stock (including most of the Reporting
Persons) entered into a Registration Rights Agreement dated as of November 30,
2004 with the Company (the "Registration Rights Agreement"), pursuant to which
the holders of the Series A Preferred Stock (i) are entitled to (A) two demand
registration rights following the first anniversary of the closing, plus (B)
immediately exercisable and unlimited piggyback registration rights, and (ii)
have the right to cause the Company to file one or more registration statements
to register the Common Stock underlying the Series A Preferred Stock for resale
by the holders of the Series A Preferred Stock on Form S-3 (or comparable form)
provided that the number of shares of underlying Common Stock to be registered
on each such registration statement have an aggregate price to the public of not
less than $250,000, in each case, pari passu with the registration rights of the
holders of the Company's Common Stock issued in the Restructuring.

         The Series A Preferred Stock (convertible into Common Stock) issued to
the Reporting Persons pursuant to the terms and conditions of the 2004
Securities Purchase Agreement was acquired by such Reporting Persons not only
for investment purposes, but also

                              Page 15 of 31 Pages


for the purpose of acquiring or maintaining, as the case may be, control of the
Company and influencing management.

         Although there is no present intention to do so, any of the Reporting
Persons may decide to make additional purchases of securities of the Company,
including Common Stock, in the future either in the open market or in private
transactions, subject to their evaluation of the Company's business, prospects
and financial condition, the market for the securities of the Company, including
Common Stock, other opportunities available to the Reporting Persons, prospects
for the respective business' of the Reporting Persons, general economic
conditions, money and stock market conditions and other future developments.

         Depending upon the results of the reviews and the other factors
mentioned above, any of the Reporting Persons, at any time, may decide to change
his or its intention with respect to the acquisition and/or retention of
securities of the Company (including, without limitation, shares of Common
Stock), including, without limitation, a determination to increase, decrease or
entirely dispose of his or its holdings of Common Stock or other securities of
the Company, although none of the Reporting Persons has any current intention to
do so.

         Any of the Reporting Persons may also approach members of the Company's
management in connection with the foregoing and/or any other matter enumerated
in clauses (a) through (j) of Item 4 of Schedule 13D and/or Webster or Ziegler
may seek to influence the management of the Company in his capacity as a
director of the Company.

         The descriptions of the 2004 Securities Purchase Agreement, the Series
A Preferred Stock and the Registration Rights Agreement (in each case, inclusive
of the other agreements which are exhibits thereto), contained in this Item 4
are summaries and are subject to and qualified in their entirety by reference to
