Item 14. Indemnification of Directors and Officers

   Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's board of directors to grant indemnification to
directors and officers in terms sufficiently broad to permit indemnification
under limited circumstances for liabilities, including reimbursement for
expenses incurred, arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article VI, Section 6.1 of our bylaws provides for mandatory
indemnification of our directors, officers and employees to the maximum extent
permitted by the Delaware General Corporation Law. Our Sixth Amended and
Restated Certificate of Incorporation provides that our officers and directors
shall not be liable for monetary damages for breach of the officers' or
directors' fiduciary duty as officers or directors to our stockholders and us.
This provision in the Sixth Amended and Restated Certificate of Incorporation
does not eliminate the officers' or directors' fiduciary duty, and, in
appropriate circumstances, equitable remedies like injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
officer or director will continue to be subject to liability for breach of the
officer's or director's duty of loyalty to us or our stockholders for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for actions leading to improper personal benefit to the
officer or director, and for payment of dividends or approval of stock
repurchases or redemptions that are unlawful under Delaware law. The provision
also does not affect an officer's or director's responsibilities under any
other law, like the federal securities laws or state or federal environmental
laws. We have entered into indemnification agreements with our officers and
directors, a form of which is attached as Exhibit 10.1 and incorporated by
reference. The indemnification agreements provide our officers and directors
with

                                      II-1


further indemnification to the maximum extent permitted by the Delaware General
Corporation Law. Reference is made to Section 7 of the underwriting agreement
contained in Exhibit 1.1 to this registration statement, indemnifying officers
and directors of ours against limited liabilities.

  (b) Financial Statement Schedules

   All schedules have been omitted because the information required to be

Item 17. Undertakings

   We undertake to provide to the underwriters at the closing specified in the
underwriting agreement, certificates in the denominations and registered in the
names as required by the underwriters to permit prompt delivery to each
purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant under the Delaware General Corporation Law, our Sixth Amended and
Restated Certificate of Incorporation or our Amended and Restated Bylaws, the
underwriting agreement, or otherwise, we have been advised that in the opinion
of the Securities and Exchange Commission this indemnification is against
public policy as expressed in the Securities Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against these
liabilities, other than the payment by us of expenses incurred or paid by a
director, officer, or controlling person of ours in the successful defense of
any action, suit or proceeding, is asserted by a director, officer or
controlling person in connection with the securities being registered in this
offering, we will, unless in the opinion of our counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether this indemnification by us is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of this issue.

   We undertake that:

   (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by us under Rule 424(b)(1) or (4) or 497(h) under the
Securities Act shall be deemed to be 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,
and the offering of these securities at that time shall be deemed to be the
initial bona fide offering.
