<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our certificate of incorporation contains certain provisions permitted under the Delaware
General Corporation Law (&#147;DGCL&#148;) relating to the liability of directors. These provisions eliminate
a director&#146;s personal liability for monetary damages resulting from a breach of fiduciary duty,
except that a director will be personally liable:

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These provisions do not limit or eliminate our rights or those of any stockholder to seek
nonmonetary relief, such as an injunction or rescission, in the event of a breach of a director&#146;s
fiduciary duty. These provisions will not alter a director&#146;s liability under federal securities
laws.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our certificate of incorporation and bylaws also provide that we must indemnify our directors
and officers to the fullest extent permitted by Delaware law and also provide that we must advance
expenses, as incurred, to our directors and officers in connection with a legal proceeding to the
fullest extent permitted by Delaware law, subject to very limited exceptions.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the DGCL, <I>inter alia</I>, authorizes a 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, other than an action by or in the right of the corporation, because such person
is or was a director, officer, employee or agent of the corporation or was serving at the request
of the corporation as a director, officer, employee or agent of another corporation or other
enterprise, against expenses, including attorneys&#146; fees, judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such suit or proceeding if he
acted in good faith and in a manner he 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 reason
to believe his conduct was unlawful. Similar indemnity is authorized for such persons against
expenses, including attorneys&#146; fees, actually and reasonably incurred in defense or settlement of
any such pending, completed or threatened action or suit by or in the right of the corporation if
such person acted in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and provided further that, unless a court of competent
jurisdiction otherwise provides, such person shall not have been adjudged liable to the
corporation. Any such indemnification may be made only as authorized in each specific case upon a
determination by the stockholders or disinterested directors 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;145 further authorizes a corporation to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or agent of another
corporation or enterprise, against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the corporation would otherwise
have the power to indemnify him. We maintain policies insuring our and our subsidiaries&#146; officers
and directors against specified liabilities for actions taken in such capacities, including
liabilities under the Securities Act of 1933.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have entered into separate indemnification agreements with our directors and officers that
may, in some cases, be broader than the specific indemnification provisions contained in our
certificate of incorporation, bylaws or the DGCL. The indemnification agreements may require us,
among other things, to indemnify our officers and directors against certain liabilities, other than
liabilities arising from willful misconduct, that may arise by reason of their status or service as
directors or officers. We believe that these indemnification arrangements are necessary to attract
and retain qualified individuals to serve as directors and officers.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Although the above discussion summarizes the material provisions of our certificate of
incorporation and bylaws, as amended, and Section&nbsp;145 of the DGCL, it is not intended to be
exhaustive and is qualified in its entirety by each of those documents and that statute.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 4%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To include any prospectus required by Section&nbsp;10(a)(3) of the Securities
Act of 1933;

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 4%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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% change in the maximum aggregate offering price set forth in the
&#147;Calculation of Registration Fee&#148; table in the effective registration statement; and

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 4%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) To include any material information with respect to the plan of

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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any of the

the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee
benefit plan annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)

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 Commission such indemnification is against public policy as expressed in the
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 Act and will be governed by the final adjudication of such issue.

Item 6.
Indemnification of Directors and Officers
.
Our certificate of incorporation contains certain provisions permitted under the Delaware
General Corporation Law ("DGCL") relating to the liability of directors. These provisions eliminate
a director's personal liability for monetary damages resulting from a breach of fiduciary duty,
except that a director will be personally liable:
II-1
Table of Contents
•
for any breach of the director's duty of loyalty to us or our stockholders;
•
for acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law;
•
under Section 174 of the DGCL relating to unlawful stock repurchases or dividends; and
•
for any transaction from which the director derives an improper personal benefit.
These provisions do not limit or eliminate our rights or those of any stockholder to seek
nonmonetary relief, such as an injunction or rescission, in the event of a breach of a director's
fiduciary duty. These provisions will not alter a director's liability under federal securities
laws.
Our certificate of incorporation and bylaws also provide that we must indemnify our directors
and officers to the fullest extent permitted by Delaware law and also provide that we must advance
expenses, as incurred, to our directors and officers in connection with a legal proceeding to the
fullest extent permitted by Delaware law, subject to very limited exceptions.
Section 145 of the DGCL,
inter alia
, authorizes a 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, other than an action by or in the right of the corporation, because such person
is or was a director, officer, employee or agent of the corporation or was serving at the request
of the corporation as a director, officer, employee or agent of another corporation or other
enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such suit or proceeding if he
acted in good faith and in a manner he 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 reason
to believe his conduct was unlawful. Similar indemnity is authorized for such persons against
expenses, including attorneys' fees, actually and reasonably incurred in defense or settlement of
any such pending, completed or threatened action or suit by or in the right of the corporation if
such person acted in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and provided further that, unless a court of competent
jurisdiction otherwise provides, such person shall not have been adjudged liable to the
corporation. Any such indemnification may be made only as authorized in each specific case upon a
determination by the stockholders or disinterested directors that indemnification is proper because
the indemnitee has met the applicable standard of conduct.
Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or agent of another
corporation or enterprise, against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the corporation would otherwise
have the power to indemnify him. We maintain policies insuring our and our subsidiaries' officers
and directors against specified liabilities for actions taken in such capacities, including
liabilities under the Securities Act of 1933.
We have entered into separate indemnification agreements with our directors and officers that
may, in some cases, be broader than the specific indemnification provisions contained in our
certificate of incorporation, bylaws or the DGCL. The indemnification agreements may require us,
among other things, to indemnify our officers and directors against certain liabilities, other than
liabilities arising from willful misconduct, that may arise by reason of their status or service as
directors or officers. We believe that these indemnification arrangements are necessary to attract
and retain qualified individuals to serve as directors and officers.
Although the above discussion summarizes the material provisions of our certificate of
incorporation and bylaws, as amended, and Section 145 of the DGCL, it is not intended to be
exhaustive and is qualified in its entirety by each of those documents and that statute.

(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 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.
(4) That, for purposes of determining any liability under the Securities Act of 1933,
each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee
benefit plan annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
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.
(5) Insofar as indemnification for liabilities arising under the Securities Act of 1933
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 Commission such indemnification is against public policy as expressed in the
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 Act and will be governed by the final adjudication of such issue.
