<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law (the &#147;DGCL&#148;) provides, in summary, that
directors and officers of Delaware corporations are entitled, under certain circumstances, to be
indemnified against all expenses and liabilities (including attorneys&#146; fees) incurred by them as a
result of suits brought against them in their capacity as directors or officers, if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to our best interests,
and, with respect to any criminal action or proceeding, if they had no reasonable cause to believe
their conduct was unlawful; provided that no indemnification may be made against expenses in
respect of any claim, issue, or matter as to which they shall have been adjudged to be liable to
us, unless and only to the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, they are fairly and reasonably entitled to indemnity for such expenses
as the court shall deem proper. Any such indemnification may be made by us only as authorized in
each specific case upon a determination by the stockholders, disinterested directors or independent
legal counsel that indemnification is proper because the indemnitee has met the applicable standard
of conduct.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation shall not be personally liable to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a director, except for
liability for any breach of the director&#146;s duty of loyalty to the corporation or its stockholders,
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions or
other distributions, or for any transaction from which the director derived an improper personal
benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our amended and restated certificate of incorporation and amended and restated by-laws provide
that we shall indemnify our directors and officers to the fullest extent permitted by law and that
no director shall be liable for monetary damages to us or our stockholders for any breach of
fiduciary duty, except to the extent provided by applicable law. We have entered into
indemnification agreements with our directors. The indemnification agreements provide
indemnification to our directors under certain circumstances for acts or omissions that may not be
covered by directors&#146; and officers&#146; liability insurance and may, in some cases, be broader than the
specific indemnification

provisions, or otherwise, the Company has been advised that in the opinion of the 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.

Table of Contents
Any statement contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified, superseded or replaced by a statement or information
contained in any other subsequently filed document incorporated herein by reference. Any such
statement so modified, superseded or replaced shall not be deemed, except as so modified,
superseded or replaced, to constitute a part of this Registration Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law (the "DGCL") provides, in summary, that
directors and officers of Delaware corporations are entitled, under certain circumstances, to be
indemnified against all expenses and liabilities (including attorneys' fees) incurred by them as a
result of suits brought against them in their capacity as directors or officers, if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to our best interests,
and, with respect to any criminal action or proceeding, if they had no reasonable cause to believe
their conduct was unlawful; provided that no indemnification may be made against expenses in
respect of any claim, issue, or matter as to which they shall have been adjudged to be liable to
us, unless and only to the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, they are fairly and reasonably entitled to indemnity for such expenses
as the court shall deem proper. Any such indemnification may be made by us only as authorized in
each specific case upon a determination by the stockholders, disinterested directors or independent
legal counsel that indemnification is proper because the indemnitee has met the applicable standard
of conduct.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation shall not be personally liable to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a director, except for
liability for any breach of the director's duty of loyalty to the corporation or its stockholders,
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions or
other distributions, or for any transaction from which the director derived an improper personal
benefit.
Our amended and restated certificate of incorporation and amended and restated by-laws provide
that we shall indemnify our directors and officers to the fullest extent permitted by law and that
no director shall be liable for monetary damages to us or our stockholders for any breach of
fiduciary duty, except to the extent provided by applicable law. We have entered into
indemnification agreements with our directors. The indemnification agreements provide
indemnification to our directors under certain circumstances for acts or omissions that may not be
covered by directors' and officers' liability insurance and may, in some cases, be broader than the
specific indemnification

provisions contained under Delaware law. We currently maintain liability
insurance for our directors and officers.
Item 7. Exemption From Registration Claimed.
Not applicable.
Item 8. Exhibits.
The exhibits listed in the Exhibit Index, which is incorporated herein by reference, are filed
as part of this Registration Statement.
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 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 a 20 percent change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in this
Registration Statement;
(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 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
by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this 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
4
Table of Contents
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) The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company'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 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 and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise, the Company has been advised that in the opinion of the 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
