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 whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by reason of the fact
that he 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,
partnership, joint venture, trust 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 action, 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 reasonable cause to believe his conduct was
unlawful. Section&nbsp;145 further provides that a corporation similarly may indemnify any such person
serving in any such capacity who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the corporation to procure a

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">request of the corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses (including attorneys&#146; fees)
actually and reasonably incurred in connection with the defense or settlement of such action or
suit 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 except that no indemnification shall be made in respect
of any claim, issue or matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery or such other court
in which such action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery
or such other court shall deem proper. Our certificate of incorporation and bylaws provide that
indemnification shall be to the fullest extent permitted by the DGCL for all our current or former
directors or officers. As permitted by the DGCL, our certificate of incorporation provides that we
will indemnify our directors against liability to us or our stockholders for monetary damages for
breach of fiduciary duty as a director, except (1)&nbsp;for any breach of the director&#146;s duty of loyalty
to us or our stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional
misconduct or knowing violation of law, (3)&nbsp;under Section&nbsp;174 of the DGCL or (4)&nbsp;for any
transaction from which a director derived an improper personal benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have also entered into indemnification agreements with all of our directors and all of our
named executive officers. These indemnification agreements are intended to permit indemnification
to the fullest extent now or hereafter permitted by the DGCL. It is possible that the applicable
law could change the degree to which indemnification is expressly permitted.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The indemnification agreements cover expenses (including attorneys&#146; fees), judgments, fines
and amounts paid in settlement incurred as a result of the fact that such person, in his or her
capacity as a director or officer, is made or threatened to be made a party to any suit or
proceeding. The indemnification agreements generally cover claims relating to the fact that the
indemnified party is or was an officer, director, employee or agent of us or any of our affiliates,
or is or was serving at our request in such a position for another entity. The indemnification
agreements also obligate us to promptly advance all reasonable expenses incurred in connection with
any claim. The indemnitee is, in turn, obligated to reimburse us for all amounts so advanced if it
is later determined that the indemnitee is not entitled to indemnification. The indemnification
provided under the indemnification agreements is not exclusive of any other indemnity rights;
however, double payment to the indemnitee is prohibited.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are not obligated to indemnify the indemnitee with respect to claims brought by the
indemnitee against:

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,

Item 6.
Indemnification of Directors and Officers
.
Section 145 of the Delaware General Corporation Law ("DGCL") provides that a corporation may
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 whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by reason of the fact
that he 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,
partnership, joint venture, trust 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 action, 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 reasonable cause to believe his conduct was
unlawful. Section 145 further provides that a corporation similarly may indemnify any such person
serving in any such capacity who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director, officer, employee or
agent of the corporation or is or was serving at the
Table of Contents
request of the corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees)
actually and reasonably incurred in connection with the defense or settlement of such action or
suit 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 except that no indemnification shall be made in respect
of any claim, issue or matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery or such other court
in which such action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all of the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery
or such other court shall deem proper. Our certificate of incorporation and bylaws provide that
indemnification shall be to the fullest extent permitted by the DGCL for all our current or former
directors or officers. As permitted by the DGCL, our certificate of incorporation provides that we
will indemnify our directors against liability to us or our stockholders for monetary damages for
breach of fiduciary duty as a director, except (1) for any breach of the director's duty of loyalty
to us or our stockholders, (2) for acts or omissions not in good faith or which involve intentional
misconduct or knowing violation of law, (3) under Section 174 of the DGCL or (4) for any
transaction from which a director derived an improper personal benefit.
We have also entered into indemnification agreements with all of our directors and all of our
named executive officers. These indemnification agreements are intended to permit indemnification
to the fullest extent now or hereafter permitted by the DGCL. It is possible that the applicable
law could change the degree to which indemnification is expressly permitted.
The indemnification agreements cover expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement incurred as a result of the fact that such person, in his or her
capacity as a director or officer, is made or threatened to be made a party to any suit or
proceeding. The indemnification agreements generally cover claims relating to the fact that the
indemnified party is or was an officer, director, employee or agent of us or any of our affiliates,
or is or was serving at our request in such a position for another entity. The indemnification
agreements also obligate us to promptly advance all reasonable expenses incurred in connection with
any claim. The indemnitee is, in turn, obligated to reimburse us for all amounts so advanced if it
is later determined that the indemnitee is not entitled to indemnification. The indemnification
provided under the indemnification agreements is not exclusive of any other indemnity rights;
however, double payment to the indemnitee is prohibited.
We are not obligated to indemnify the indemnitee with respect to claims brought by the
indemnitee against:
•
us, except for:
•
claims regarding the indemnitee's rights under the indemnification agreement;
•
claims to enforce a right to indemnification under any statute or law; and
•
counter-claims against us in a proceeding brought by us against the indemnitee; or
•
any other person, except for claims approved by our board of directors.
We have obtained director and officer liability insurance for the benefit of each of the above
indemnitees. These policies include coverage for losses for wrongful acts and omissions and to
ensure our performance under the indemnification agreements. Each of the indemnitees are named as
an insured under such policies and provided with the same rights and benefits as are accorded to
the most favorably insured of our directors and officers.

Item 9.
Undertakings
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:
(a) To include any prospectus required by Section 10(a)(3) of the Securities Act of
1933 (the "Securities Act");
(b) 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
Table of Contents
percent change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and
(c) 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 (1)(a) and (1)(b) do not apply if the information required to be
included in a post-effective amendment by those paragraphs is contained in periodic reports filed
with or furnished or furnished to the Commission by the registrant 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, 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, each filing
of the registrant'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 the 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 may be
permitted to directors, officers and controlling persons of the registrant, the registrant 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 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.
