ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article Eighth of the Company's Certificate of Incorporation and Article X
of the Companys Bylaws provide for mandatory indemnification to at least the
extent specifically allowed by Section 145 of the General Corporation Law of
the State of Delaware (the GCL).
 
  Pursuant to Section 145 of the GCL, the Company generally has the power to
indemnify its current and former directors, officers, employees and agents
against expenses and liabilities incurred by them in connection with any suit
to which they are, or are threatened to be made, a party by reason of their
serving in such positions so long as they acted in good faith and in a manner
in which they reasonably believed to be, or not opposed to, the best interest
of the Company, and with respect to any criminal action, they had no
reasonable cause to believe their conduct was unlawful. With respect to suits
by or in the right of the Company, however, indemnification is generally
limited to attorneys' fees and other expenses and is not available if such
person is adjudged to be liable to the Registrant unless the court determines
that indemnification is appropriate. The statute expressly provides that the
power to indemnify authorized thereby is not exclusive of any rights granted
under any bylaw, agreement, vote of stockholders or disinterested directors,
or otherwise. The Company also has the power to purchase and maintain
insurance for such persons.
 
  The above discussion of the Company's Certificate of Incorporation and
Bylaws and Section 145 of the GCL is not intended to be exhaustive and is
qualified in its entirety by such document and statute.
 
  Directors and Officers are insured at the Company's expense, against certain
liabilities which might arise out of their employment and which are not
subject to indemnification under the Bylaws.
 
  Reference is made to the form of Underwriting Agreement, filed as Exhibit
1.1 hereto, which contains provisions for indemnification of the Company, its
directors, officers and any controlling persons by the Underwriters against
certain liabilities for information furnished by the Underwriters.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  In connection with the organization of the Company, in May 1998 an aggregate
of 1,000 shares of Common Stock were issued to the McNair Interests and the
Minority Interests pursuant to Section 4(2) of the Securities Act of 1993, as

  As permitted by Item 601(b)(4) of Regulation S-K, the Company has not filed
with this Registration Statement certain instruments defining the rights of
holders of long-term debt of the Company, if any, because the total amount of
securities authorized under any of such instruments does not exceed 10% of the
total assets of the Company and its subsidiaries on a consolidated basis. The
Company agrees to furnish a copy of any such agreements to the Securities and
Exchange Commission upon request.
 
  (b) Financial Statement Schedules: None.
 
ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Company of expenses incurred or paid by a director, officer or controlling
person of the Company 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 Company 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 and will be governed by the final adjudication of such issue.
 
  The undersigned Company hereby undertakes to provide to the Underwriters at
the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Company hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act, the
      information omitted from the form of prospectus filed as a part of this
      Registration Statement in reliance upon Rule 430A and contained in a
      form of prospectus filed by the Company pursuant to Rule 424(b)(1) or
      (4) or 497(h) under the Securities Act shall be deemed to be a part of
      this Registration Statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act,
      each post-effective amendment that contains a form of prospectus 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.
