ITEM 9.   UNDERTAKINGS.

(A)   RULE 415 OFFERING.

      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; and

                                      II-2

            (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) 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
            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)   FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE.

      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 Exchange Act (and, where applicable, each filing of an employee
      benefit plan's annual report pursuant to 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 that time shall be
      deemed to be the initial bona fide offering thereof.

(H)   STATEMENT REQUIRED BY ITEM 512(H) IN CONNECTION WITH FILING OF
      REGISTRATION STATEMENT ON FORM S-8.

      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
      Commission such indemnification is against public policy as expressed in
      the Securities Act of 1933 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 Securities Act of 1933 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-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Houston, State of Texas on April 15, 1998.
