pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities and Exchange
Act of 1934, as amended (the "1934 Act") (other than Current Reports or portions

Statement and to be a part hereof from their respective dates of filing.

         Any statement contained in a document incorporated or deemed to be

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Ronald C. Potter, Esq., whose opinion of counsel is attached hereto as
Exhibit 5, is Vice President, General Counsel and Corporate Secretary of the
Registrant. As of April 29, 2005, Mr. Potter directly or indirectly beneficially
owned, subject in some cases to certain restrictions, 18,997 shares of Common
Stock of the Company and had the right to exercise options to receive an
additional 129,896 shares.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the General Corporation Law of the State of Delaware
empowers a Delaware corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or 



                                      II-1




investigative (other than an action by or in the right of the corporation) by
reason of the fact that such person is or was a director, officer, employee or
agent of such corporation or is or was serving at the request of such
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The indemnity may include
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that such person acted in good faith
and in a manner such person reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful. A Delaware corporation may indemnify directors, officers, employees
and other agents of such corporation in an action by or in the right of the
corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the person to be indemnified has been
adjudged to be liable to the corporation. Where a director, officer, employee or
agent of the corporation is successful on the merits or otherwise in the defense
of any action, suit or proceeding referred to above or in defense of any claim,
issue or matter therein, the corporation must indemnify such person against the
expenses (including attorneys' fees) which he or she actually and reasonably
incurred in connection therewith.

         The By-laws of Registrant contain provisions that provide for
indemnification of officers and directors to the fullest extent permitted by,
and in the manner permissible under, the General Corporation Law of the State of
Delaware. In addition, the Registrant has entered into specific agreements with
the directors and officers of the Registrant providing for indemnification of
such persons under certain circumstances.

         As permitted by Section 102(b)(7) of the General Corporation Law of the
State of Delaware, the Registrant's Certificate of Incorporation contains a
provision eliminating the personal liability of a director to the Registrant or
its stockholders for monetary damages for breach of fiduciary duty as a
director, subject to certain exceptions.

         The Registrant maintains policies insuring its officers and directors
against certain civil liabilities, including liabilities under the 1933 Act.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 9.  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 1933 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)(1)(i) and (a)(1)(ii) above do
         not apply if the registration statement is on Form S-3, Form S-8, or
         Form F-3, and 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 Securities and Exchange
         Commission by the Registrant pursuant to Section 13 or Section 15(d) of
         the 1934 Act that are incorporated by reference in the registration
         statement.

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

                  (3) 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.

         (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the 1934 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) Insofar as indemnification for liabilities arising under the 1933
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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the 1933 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 



                                      II-3




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 1933 Act and
will be governed by the final adjudication of such issue.



                                      II-4




                                   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 May 6, 2005.
