<P><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our restated certificate of incorporation (the &#147;certificate&#148;) provides
that, except to the extent prohibited by Delaware law, our directors shall not
be personally liable to us or our stockholders for monetary damages for breach
of their fiduciary duty as directors. Under Delaware law, the directors have a
fiduciary duty to us which is not eliminated by this provision of our
certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available. In
addition, each director will continue to be subject to liability under Delaware
law for breach of their duty of loyalty to us or our stockholders; for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or which involve intentional misconduct or knowing violations of
law; for actions leading to improper personal benefit to the director; and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by Delaware law. This provision also does not affect the directors&#146;
responsibilities under any other laws, such as the federal securities laws or
state or federal environmental laws.
</FONT>
<P><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law allows a corporation
to indemnify its directors and officers and to purchase insurance with respect
to liability arising out of their capacity or status as directors and officers,
provided that the indemnification does not eliminate or limit the liability of
a director for (i)&nbsp;any breach of the director&#146;s duty of loyalty to us or our
stockholders, (ii)&nbsp;acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii)&nbsp;unlawful payments
of dividends or unlawful stock purchases or redemptions, and (iv)&nbsp;any
transaction from which the director derived an improper personal benefit.
</FONT>
<P><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Delaware law further provides that the permitted indemnification shall not
be deemed exclusive of any other rights to which the directors and officers may
be entitled under our bylaws, any agreement, a vote of stockholders or
otherwise. Our certificate eliminates the personal liability of directors to
the fullest extent permitted by Delaware law. In addition, our certificate
provides that we may fully indemnify any person through bylaw provisions,
agreements with such person, vote of stockholders or disinterested directors or
otherwise, in excess of the indemnification and advancement otherwise permitted
by Section&nbsp;145 of the Delaware General Corporation Law, subject only to limits
created by applicable Delaware law (statutory or non-statutory), with respect
to action for breach of duty to us, our stockholders or others.
</FONT>
<P><FONT size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have also obtained directors&#146; and officers&#146; liability insurance, the
effect of which is to indemnify our directors and officers against certain
damages and expenses because of certain claims made against them caused by

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

year ended December 31, 2001;

All reports and definitive proxy or information statements filed under
Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), after the date of this Registration Statement and

Table of Contents
Item 6. Indemnification of Directors and Officers
Our restated certificate of incorporation (the "certificate") provides
that, except to the extent prohibited by Delaware law, our directors shall not
be personally liable to us or our stockholders for monetary damages for breach
of their fiduciary duty as directors. Under Delaware law, the directors have a
fiduciary duty to us which is not eliminated by this provision of our
certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available. In
addition, each director will continue to be subject to liability under Delaware
law for breach of their duty of loyalty to us or our stockholders; for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or which involve intentional misconduct or knowing violations of
law; for actions leading to improper personal benefit to the director; and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by Delaware law. This provision also does not affect the directors'
responsibilities under any other laws, such as the federal securities laws or
state or federal environmental laws.
Section 145 of the Delaware General Corporation Law allows a corporation
to indemnify its directors and officers and to purchase insurance with respect
to liability arising out of their capacity or status as directors and officers,
provided that the indemnification does not eliminate or limit the liability of
a director for (i) any breach of the director's duty of loyalty to us or our
stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) unlawful payments
of dividends or unlawful stock purchases or redemptions, and (iv) any
transaction from which the director derived an improper personal benefit.
Delaware law further provides that the permitted indemnification shall not
be deemed exclusive of any other rights to which the directors and officers may
be entitled under our bylaws, any agreement, a vote of stockholders or
otherwise. Our certificate eliminates the personal liability of directors to
the fullest extent permitted by Delaware law. In addition, our certificate
provides that we may fully indemnify any person through bylaw provisions,
agreements with such person, vote of stockholders or disinterested directors or
otherwise, in excess of the indemnification and advancement otherwise permitted
by Section 145 of the Delaware General Corporation Law, subject only to limits
created by applicable Delaware law (statutory or non-statutory), with respect
to action for breach of duty to us, our stockholders or others.
We have also obtained directors' and officers' liability insurance, the
effect of which is to indemnify our directors and officers against certain
damages and expenses because of certain claims made against them caused by
their negligent act, error or omission.

Item 9. Undertakings
A.
The 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;
(ii) To reflect in the prospectus any facts or events arising after the
effective date of this 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 this
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 20% change in
the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and
(iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement;
provided, however, that clauses (1)(i) and (1)(ii) shall not apply if the
information required to be included in a post-effective amendment by those
clauses is contained in periodic reports filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference into this Registration Statement.
II-3
Table of Contents
(2) That, for the purpose of determining any liability under the
Securities 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; and
(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 Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is
incorporated by reference into this 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 may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the SEC,
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
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 and will be governed by the final adjudication of such issue.
