                              SELLING SHAREHOLDERS

         This Prospectus relates to shares of Common Stock that the selling
shareholders have acquired or will acquire upon the exercise of options granted
under the 1992 Plan. Each of the selling shareholders is a director or executive
officer of the Company. The Shares to which this Prospectus relates may be
"control securities" within the meaning of General Instruction C to Form S-8.
Neither the statements in this Prospectus or in the related registration
statement, nor the delivery of this Prospectus in connection with the
disposition of Shares by any of the selling shareholders, will be an admission
by the Company or any of the selling shareholders that the selling shareholder
is in a control relationship with the Company.

         The table attached as Annex A sets forth, with respect to the selling
shareholders and based on the information available to us as of the date
thereof, the name of each selling shareholder, the nature of any position,
office, or other material relationship which the selling shareholder has had
within the past three years with the Company and its affiliates, the number of
shares of Common Stock owned by each selling shareholder prior to the offering,
the number of Shares available for resale under this Prospectus, and the number
of shares and percentage of our outstanding Common Stock to be owned by each
selling shareholder after giving effect to this offering. We do not know whether
any of the selling shareholders will sell any or all of the Shares offered by
this Prospectus. The inclusion of Shares in the table in Annex A does not
constitute a commitment to sell any Shares by any of the selling shareholders
named therein.

                                 USE OF PROCEEDS

         The Company will not receive any of the proceeds from the sale of any
of the Shares by the selling shareholders.

                              PLAN OF DISTRIBUTION

         The Shares may be sold from time to time by the selling shareholders or
by their respective pledgees, donees, transferees, or other successors in
interest. Such sales may be made in the Nasdaq National Market, otherwise in the
over-the-counter market, on one or more securities exchanges, or otherwise at
prices and at terms then prevailing, at prices related to the then-current
market price, or in negotiated transactions. The Shares may be sold by one or
more of the following methods, without limitation:

         o        Ordinary brokerage transactions and transactions in which the
                  broker-dealer solicits purchasers;



                                       5
<PAGE>

         o        A block trade in which the broker-dealer so engaged will
                  attempt to sell the Shares as agent but may position and
                  resell a portion of the block as principal to facilitate the
                  transaction;

         o        Purchases by a broker-dealer as principal and resale by such
                  broker-dealer for its account pursuant to this Prospectus;

         o        An exchange distribution in accordance with the rules of such
                  exchange; and

         o        Face-to-face transactions between sellers and purchasers with
                  or without a broker-dealer.

         In effecting sales of the Shares, broker-dealers engaged by the selling
shareholders may arrange for the participation of other broker-dealers.
Broker-dealers may receive compensation in the form of underwriting discounts,
concessions, or commissions from the selling shareholders in amounts to be
negotiated immediately prior to the sale. Such broker-dealers and any other
participating broker-dealers may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales.

         Once the Company has been notified by a selling shareholder that any
material arrangement has been entered into with a broker-dealer for the sale of
Shares through a block trade, exchange or secondary distribution, or a purchase
by a broker-dealer, a supplement to the Prospectus will be filed, if required,
pursuant to Rule 424(b) under the Securities Act, disclosing: the participating
broker-dealer(s); the number of Shares involved; the price at which such Shares
were sold; the commissions paid or discounts or concessions allowed to such
broker-dealer(s), where applicable; that such broker-dealer(s) did not conduct
any investigation to verify the information set out or incorporated by reference
in this Prospectus (as supplemented); and other facts material to the
transaction.

         In addition to any sales of Shares under this Prospectus, the selling
shareholders may, at the same time, sell any shares of Common Stock owned by
them, including Shares covered by this Prospectus, pursuant to Rule 144 under
the Securities Act.

         There is no assurance that the selling shareholders will sell any or
all of the Shares offered hereby.

         The Company will pay all expenses incident to the offering and sale of
the Shares pursuant to this Prospectus other than commissions and discounts of
underwriters, dealers, or agents.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 2.02-1 of the Texas Business Corporation Act, as amended,
authorizes the Company to indemnify our officers and directors and certain other
persons in certain instances. In addition, Section 2.02-1 and our Bylaws require
that we indemnify any director or officer against reasonable expenses he incurs
in connection with a wholly successful defense of a proceeding in which he is a
named defendant or respondent because he is or was a director or officer. This
indemnification will only occur with the determination that the person (i)
conducted himself in good faith, (ii) reasonably believed, in the case of
conduct in his official capacity as our director or officer, that his conduct
was in our best interests and, in all other cases, that his conduct was at least
not opposed to our best interests, and (iii), in the case of any criminal
proceeding, had no reasonable cause to believe his conduct was unlawful.
However, if the director or officer is found liable to us or is found liable on
the basis that personal benefit was improperly received, the indemnification
shall be limited to reasonable expenses actually incurred in connection with the
proceeding and shall not be made in respect of any proceeding in which the
person shall have been found liable for willful or intentional misconduct in the
performance of his duty to the Company. Indemnification shall not be made in
respect of any proceeding in which the person shall have been found liable for
willful or intentional misconduct in the performance of his duty to us.




                                       9
<PAGE>

         Section 2.02-1 and our Bylaws generally require determinations that the
person to be indemnified has satisfied the prescribed conduct and belief
standards, as determined by directors who are not themselves then named
defendants or respondents in the proceeding, by a special legal counsel selected
by the Board of Directors or a committee thereof, or by shareholders in a vote
that excludes the shares held by directors and officers who are named defendants
or respondents in the proceeding.

         The Bylaws further require us to pay or reimburse expenses incurred by
a director or officer in connection with his appearance as a witness or other
participation in a proceeding at a time when he is not a named defendant or
respondent in the proceeding. We must also advance reasonable expenses to a
director or officer upon receipt of a good faith affirmation by him that he has
met the standard of conduct necessary for indemnification and a written
undertaking to repay such advances if it is ultimately determined that he has
not met those requirements.

         The Bylaws permit us to indemnify and advance expenses to an officer,
employee, or agent to such further extent as may be consistent with law,
including persons serving another entity in various capacities at our request.
The Bylaws also authorize us to purchase and maintain insurance or make other
arrangements on behalf of directors, officers, employees, and agents against or
in respect of liabilities.

         Any indemnification of or advance of expenses to a director under the
Bylaws or any statute must be reported in writing to shareholders not later than
the notice of the next shareholders' meeting or the next submission to
shareholders of a consent to action without a meeting and, in any event, within
the 12-month period immediately following the indemnification or advance.

ITEM 9.  UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (a)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement;
                           and

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in the registration statement;

                  Provided, however, that paragraphs (a)(i) and (a)(ii) do not
                  apply if the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed by the registrant pursuant to Section
                  13 or Section 15(d) of the Exchange Act that are incorporated
                  by reference in this registration statement.

         (b)      That, for the purpose of determining any liability under the
                  Securities Act; each such post-effective amendment shall be
                  deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof; and

         (c)      To remove from registration by means of post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein and the offering of such securities at the time shall be deemed
to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by




                                       11
<PAGE>

such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         Pursuant to the requirements of the Securities Act, United States Lime

the offer and sale of the Shares on behalf of selling shareholders may be deemed
to be "underwriters" for purposes of the Securities Act of 1933, as amended (the

the Securities Act. See "PLAN OF DISTRIBUTION." The Company will pay all
expenses incident to the offering and sale of the Shares to the public other
than commissions and discounts of underwriters, dealers, or agents. The Company
will not receive any proceeds from the sale of the Shares by the selling
shareholders.

         There is no assurance that any of the selling shareholders will sell
any of the Shares or that all of the Shares will be sold. The Company's Common

                              SELLING SHAREHOLDERS

         This Prospectus relates to shares of Common Stock that the selling
shareholders have acquired or will acquire upon the exercise of options granted
under the 1992 Plan. Each of the selling shareholders is a director or executive
officer of the Company. The Shares to which this Prospectus relates may be
"control securities" within the meaning of General Instruction C to Form S-8.
Neither the statements in this Prospectus or in the related registration
statement, nor the delivery of this Prospectus in connection with the
disposition of Shares by any of the selling shareholders, will be an admission
by the Company or any of the selling shareholders that the selling shareholder
is in a control relationship with the Company.

         The table attached as Annex A sets forth, with respect to the selling
shareholders and based on the information available to us as of the date
thereof, the name of each selling shareholder, the nature of any position,
office, or other material relationship which the selling shareholder has had
within the past three years with the Company and its affiliates, the number of
shares of Common Stock owned by each selling shareholder prior to the offering,
the number of Shares available for resale under this Prospectus, and the number
of shares and percentage of our outstanding Common Stock to be owned by each
selling shareholder after giving effect to this offering. We do not know whether
any of the selling shareholders will sell any or all of the Shares offered by
this Prospectus. The inclusion of Shares in the table in Annex A does not
constitute a commitment to sell any Shares by any of the selling shareholders
named therein.

                                 USE OF PROCEEDS

         The Company will not receive any of the proceeds from the sale of any
of the Shares by the selling shareholders.

                              PLAN OF DISTRIBUTION

         The Shares may be sold from time to time by the selling shareholders or
by their respective pledgees, donees, transferees, or other successors in
interest. Such sales may be made in the Nasdaq National Market, otherwise in the
over-the-counter market, on one or more securities exchanges, or otherwise at
prices and at terms then prevailing, at prices related to the then-current
market price, or in negotiated transactions. The Shares may be sold by one or
more of the following methods, without limitation:

         o        Ordinary brokerage transactions and transactions in which the
                  broker-dealer solicits purchasers;

                                       5
o        A block trade in which the broker-dealer so engaged will
                  attempt to sell the Shares as agent but may position and
                  resell a portion of the block as principal to facilitate the
                  transaction;

         o        Purchases by a broker-dealer as principal and resale by such
                  broker-dealer for its account pursuant to this Prospectus;

         o        An exchange distribution in accordance with the rules of such
                  exchange; and

         o        Face-to-face transactions between sellers and purchasers with
                  or without a broker-dealer.

         In effecting sales of the Shares, broker-dealers engaged by the selling
shareholders may arrange for the participation of other broker-dealers.
Broker-dealers may receive compensation in the form of underwriting discounts,
concessions, or commissions from the selling shareholders in amounts to be
negotiated immediately prior to the sale. Such broker-dealers and any other
participating broker-dealers may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales.

         Once the Company has been notified by a selling shareholder that any
material arrangement has been entered into with a broker-dealer for the sale of
Shares through a block trade, exchange or secondary distribution, or a purchase
by a broker-dealer, a supplement to the Prospectus will be filed, if required,
pursuant to Rule 424(b) under the Securities Act, disclosing: the participating
broker-dealer(s); the number of Shares involved; the price at which such Shares
were sold; the commissions paid or discounts or concessions allowed to such
broker-dealer(s), where applicable; that such broker-dealer(s) did not conduct
any investigation to verify the information set out or incorporated by reference
in this Prospectus (as supplemented); and other facts material to the
transaction.

         In addition to any sales of Shares under this Prospectus, the selling
shareholders may, at the same time, sell any shares of Common Stock owned by
them, including Shares covered by this Prospectus, pursuant to Rule 144 under
the Securities Act.

         There is no assurance that the selling shareholders will sell any or
all of the Shares offered hereby.

         The Company will pay all expenses incident to the offering and sale of
the Shares pursuant to this Prospectus other than commissions and discounts of
underwriters, dealers, or agents.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 2.02-1 of the Texas Business Corporation Act, as amended,
authorizes the Company to indemnify our officers and directors and certain other
persons in certain instances. In addition, Section 2.02-1 and our Bylaws require
that we indemnify any director or officer against reasonable expenses he incurs
in connection with a wholly successful defense of a proceeding in which he is a
named defendant or respondent because he is or was a director or officer. This
indemnification will only occur with the determination that the person (i)
conducted himself in good faith, (ii) reasonably believed, in the case of
conduct in his official capacity as our director or officer, that his conduct
was in our best interests and, in all other cases, that his conduct was at least
not opposed to our best interests, and (iii), in the case of any criminal
proceeding, had no reasonable cause to believe his conduct was unlawful.
However, if the director or officer is found liable to us or is found liable on
the basis that personal benefit was improperly received, the indemnification
shall be limited to reasonable expenses actually incurred in connection with the
proceeding and shall not be made in respect of any proceeding in which the
person shall have been found liable for willful or intentional misconduct in the
performance of his duty to the Company. Indemnification shall not be made in
respect of any proceeding in which the person shall have been found liable for
willful or intentional misconduct in the performance of his duty to us.

                                       9
Section 2.02-1 and our Bylaws generally require determinations that the
person to be indemnified has satisfied the prescribed conduct and belief
standards, as determined by directors who are not themselves then named
defendants or respondents in the proceeding, by a special legal counsel selected
by the Board of Directors or a committee thereof, or by shareholders in a vote
that excludes the shares held by directors and officers who are named defendants
or respondents in the proceeding.

         The Bylaws further require us to pay or reimburse expenses incurred by
a director or officer in connection with his appearance as a witness or other
participation in a proceeding at a time when he is not a named defendant or
respondent in the proceeding. We must also advance reasonable expenses to a
director or officer upon receipt of a good faith affirmation by him that he has
met the standard of conduct necessary for indemnification and a written
undertaking to repay such advances if it is ultimately determined that he has
not met those requirements.

         The Bylaws permit us to indemnify and advance expenses to an officer,
employee, or agent to such further extent as may be consistent with law,
including persons serving another entity in various capacities at our request.
The Bylaws also authorize us to purchase and maintain insurance or make other
arrangements on behalf of directors, officers, employees, and agents against or
in respect of liabilities.

         Any indemnification of or advance of expenses to a director under the
Bylaws or any statute must be reported in writing to shareholders not later than
the notice of the next shareholders' meeting or the next submission to
shareholders of a consent to action without a meeting and, in any event, within
the 12-month period immediately following the indemnification or advance.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9.  UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (a)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement;
                           and

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in the registration statement;

                  Provided, however, that paragraphs (a)(i) and (a)(ii) do not
                  apply if the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed by the registrant pursuant to Section
                  13 or Section 15(d) of the Exchange Act that are incorporated
                  by reference in this registration statement.

         (b)      That, for the purpose of determining any liability under the
                  Securities Act; each such post-effective amendment shall be
                  deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof; and

         (c)      To remove from registration by means of post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein and the offering of such securities at the time shall be deemed
to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by

                                       11
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
