(The Schedule and Amendment Nos. 1, 2, 3, 4, 5, 6, 7, 8 and this Amendment No.
9 are collectively referred to herein as the "Schedule" where the context so
permits.)  All defined terms refer to terms defined herein, in the Schedule

Amendment No. 9, the Schedule and Amendment Nos. 1, 2, 3, 4, 5, 6, 7 and 8
speak as of their respective dates.  The Schedule and Amendment Nos. 1, 2, 3,

Item 2.  Identity and Background

     Subsections (a)-(c) of Item 2.  Identity and Background appearing in the
Schedule are amended and revised to read in their entirety to read as follows:

     (a)-(c)  This Amendment No. 9 is filed by (i) Value Partners, Ltd. ("VP"),
a Texas limited partnership, (ii) Ewing & Partners (formerly known as Fisher
Ewing Partners) ("E&P"), a Texas general partnership and the general partner
of VP, and (iii) Timothy G. Ewing, a general partner of E&P.  Mr. Ewing, E&P

Item 4.  Purpose of Transaction

     Item 4.  Purpose of Transaction appearing in the Schedule is amended and
revised to read in its entirety as follows:

     The purpose of the acquisition of shares of the Issuer's Exchangeable
Preferred Stock by VP and E&P is for investment.  The shares reported on this
Schedule were not acquired with the intention of exercising control over the
Issuer.  Although the Exchangeable Preferred Stock is non-voting stock, it
has the exclusive right to vote as a class for up to two directors to the
Board of Directors of the Issuer if at any time or times dividends payable on
the Exchangeable Preferred Stock shall be in arrears and unpaid for three
consecutive full semi-annual periods.  The two directors that may be elected
by the holders of the Exchangeable Preferred Stock constitute a minority of
the total Board of Directors of the Issuer, which results in the holders of
the Exchangeable Preferred Stock being unable to exercise control over the
Issuer.

     The Issuer's Form 10-Q for the quarterly period ended March 31, 1998
stated that no dividends on the Exchangeable Preferred Stock were declared or
paid during fiscal years 1992 through 1997.  Consequently, VP and E&P were of
the belief that, pursuant to the terms of the Issuer's amended and restated
articles of incorporation, there were two vacancies on the Board of Directors
of the Issuer, constituting the "Class D" directors, who may be elected
exclusively by the holders of the Exchangeable Preferred Stock.

     As described in Amendment No. 6, the Issuer was ordered by the United
States District Court for the Eastern District of Virginia, Alexandria
Division (the "Court"), to hold a special meeting ("Special Meeting") of the
holders of the Exchangeable Preferred Stock for the purpose of electing the
two Class D directors.  At a Special Meeting held on July 31, 1998, the two
Class D directors nominated by VP, Julio E. Heurtematte, Jr. and Malcolm M.B.
Sterrett, were elected as directors of the Issuer.

     VP spent approximately $200,000 in its efforts to require that the
Issuer hold a Special Meeting and elect the Class D directors.  VP did not
obtain reimbursement from the Issuer or any other holder of the Exchangeable
Preferred Stock.

     Mr. Heurtematte resigned from the Issuer's Board of Directors in 1999
and was replaced by John C. Boland, who was appointed to the Board of Directors
on December 17, 1999 as a Class D director.  At the annual meeting of
stockholders held on November 6, 2001, Geoffrey Baker and Malcolm Sterrett
were elected as Class D directors.  The Class D directors are elected
annually, and VP has submitted nominations for the Class D directors each
year.  The current Class D directors were nominated by VP.

     While VP and E&P intend to exercise their rights as stockholders, except
as set forth herein, none of VP, E&P or Mr. Ewing currently has any plans or
proposals which relate to or would result in:  (a) the acquisition by any
person of additional securities of the Issuer or the disposition of securities
of the Issuer; (b) an extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving the Issuer or any of its
subsidiaries; (c) a sale or transfer of a material amount of assets of the
Issuer or any of its subsidiaries; (d) any change in

CUSIP NO. 87969B 20 0                13D/A                   Page 7 of 9 Pages



the present Board of Directors or management of the Issuer, including any plans
or proposals to change the number or term of directors or to fill any existing
vacancies on the Board; (e) any material change in the present capitalization
or dividend policy of the Issuer; (f) any other material change in the Issuer's
business or corporate structure; (g) changes in the Issuer's Articles of
Incorporation, Bylaws or instruments corresponding thereto or other actions
which may impede the acquisition of control of the Issuer by any person; (h)
causing a class of securities of the Issuer to be delisted from a national
securities exchange or to cease to be authorized or quoted in an inter-dealer
quotation system of a registered national securities association; (i) a class
of equity securities of the Issuer becoming eligible for termination of
registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any
action similar to any of those enumerated above.

     The Reporting Persons have proposed a recapitalization of the Issuer,
with the general terms providing for the following:  (1) the issuance of
additional common stock by the Issuer, a portion of which VP would be willing
to commit to purchase; (2) the Issuer's use of the proceeds from the sale of
the common stock to retire the outstanding senior subordinated notes at
their face amount with no prepayment penalty; (3)  the conversion of the
Exchangeable Preferred Stock for common stock; (4) the appointment of a new
director acceptable to the persons who purchase the common stock in clause (1)
above, bringing the size of the Board to nine members; (5) the registration of
the common stock under the Securities Act of 1933; and (6) the adoption of a
new stock option plan for management.

     The Reporting Persons note that the Issuer had a total stockholders'
deficit of $82.6 million at September 30, 2004.  The Issuer has appointed a
committee of independent directors to consider any and all proposals and
alternatives with respect to the possible restructuring of the capital stock
of the Issuer.

     The Reporting Persons have had and intend to have discussions with other
holders of the Issuer's securities from time to time with respect to the
Issuer, its operations and prospects, and general corporate governance matters.
The Reporting Persons may in the future elect to form a group with one or more
other holders of the Issuer's securities if deemed necessary to (1) effectuate
appropriate changes in the manner in which the Issuer conducts its business,
(2) make the Board of Directors more responsive to stockholder concerns, or
(3) facilitate a recapitalization of the Issuer.

     The Reporting Persons have had discussions from time to time with the
Class D directors, who were previously nominated by VP, as well as other
directors and management of the Issuer.  However, the Class D directors act
independently of the Reporting Persons.

     Notwithstanding the above, the Reporting Persons may vote the Exchangeable
Preferred Stock as permitted by the Issuer's governing corporate documents.  In
addition, the Reporting Persons may exercise any or all rights available to
holders of the Exchangeable Preferred Stock.  In the future, the Reporting
Persons may determine to purchase additional shares of the Issuer's Exchangeable
Preferred Stock (or other securities of the Issuer) or may determine to sell
shares of the Issuer's Exchangeable Preferred Stock.  Any such determination
will depend on a number

CUSIP NO. 87969B 20 0                13D/A                   Page 8 of 9 Pages



of factors, including market prices, the Issuer's prospects, VP's or E&P's
capital requirements, and alternative investments.

Item 5.  Interest in Securities of the Issuer.

     (a)  According to the Issuer's Report on Form 10-Q for the quarter ended
September 30, 2004, a total of 3,185,586 shares of Exchangeable Preferred Stock
were issued and outstanding as of September 30, 2004.  As of March 17, 2005,
VP beneficially owns 561,317 shares of Exchangeable Preferred Stock,
representing 17.6% of the issued and outstanding Exchangeable Preferred Stock.

     (b)  VP has the sole power to vote and dispose of the Exchangeable
Preferred Stock beneficially owned by it.  VP does not share the power to vote
or to direct the vote of, or the power to dispose or to direct the disposition
of, the Exchangeable Preferred Stock owned by it.  E&P, EAM and Mr. Ewing do
not directly own any shares of Exchangeable Preferred Stock of the Issuer.
However, E&P, as a general partner of VP, may be deemed, for purposes of
determining beneficial ownership pursuant to Rule 13d-3, to have the shared
power with VP to vote or direct the vote of, and the shared owner with VP to
dispose of or to direct the disposition of, the Exchangeable Preferred Stock
owned by VP.  Mr. Ewing, as a general partner and the Managing Partner of E&P,
may be deemed, for purposes of determining beneficial ownership pursuant to
Rule 13d-3, to have shared power with VP to vote or to direct the vote of, and
the shared power to dispose or to direct the disposition of, the Exchangeable
Preferred Stock owned by VP.  Although EAM holds a 1% general partner interest
in E&P, EAM does not have any shared voting or dispositive power over the
Exchangeable Preferred Stock owned by VP, as the general partnership agreement
for E&P gives such power solely to Mr. Ewing as the Managing Partner of E&P.

     (c)  On March 17, 2005, VP sold 153,000 shares of Exchangeable Preferred
Stock through a broker at a price of $5.85 per share, less a broker's
commission.

     (d)  E&P and Mr. Ewing may be deemed to have the power to direct the
receipt of dividends from, or the proceeds from the sale of, the Exchangeable
Preferred Stock owned by VP.

     (e)  Not applicable.
