ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article 2.02.A.(16) and Article 2.02-1 of the Texas Business Corporation
Act and Article V of the Company's Amended and Restated Bylaws provide the
Company with broad powers and authority to indemnify its directors and officers
and to purchase and maintain insurance for such purposes. Pursuant to such
statutory and Bylaw provisions, the Company has purchased insurance against
certain costs of indemnification that may be incurred by it and by its officers
and directors.

     Additionally, Article IX of the Company's Amended and Restated Articles of
Incorporation provides that a director of the Company is not liable to the
Company for monetary damages for any act or omission in the director's capacity
as director, except that Article IX does not eliminate or limit the liability of
a director for (i) any breach of such director's duty of loyalty to the Company
or its shareholders, (ii) any act or omission not in good faith that constitutes
a breach of duty of such director to the Company or an act or omission that
involves intentional misconduct or a knowing violation of law, (iii) a
transaction from which such director received an improper benefit, whether or
not the benefit resulted from an action taken within the scope of the director's
office or (iv) an act or omission for which the liability of a director is
expressly provided for by statute.

     Article IX also provides that any subsequent amendments to Texas statutes
that further limit the liability of directors will inure to the benefit of the
directors, without any further action by shareholders. Any repeal or
modification of Article IX shall not adversely affect any right of protection of
a director of the Company existing at the time of the repeal or modification.

     See "Item 17. Undertakings" for a description of the Commission's position
regarding such indemnification provisions.

ITEM 17.  UNDERTAKINGS

     (a) The undersigned registrant hereby undertakes:

          (1) 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 of 1933;

             (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. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate

                                       II-2


        offering price set forth in the "Calculation of Registration Fee" table
        in the effective registration statement;

             (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(1)(i) and a(1)(ii) of this section do
     not apply if the information required to be included in a post-effective
     amendment by those paragraphs is contained in periodic reports filed with
     or furnished to the Commission by the registrant pursuant to section 13 or
     section 15d of the Securities Exchange Act of 1934 that are incorporated by
     reference in the registration statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, 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.

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

     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 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 that time shall be deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 Securities and Exchange
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 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.

                                       II-3


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Post-Effective
Amendment to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Houston, the State of Texas, on September 6, 2002.
