</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law provides generally that a corporation
shall have the power, and in some cases is required, to indemnify an agent, including an officer or
director, 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 or she
is or was a director, officer, employee or agent of the corporation, against certain expenses,
judgments, fines, settlements and other amounts under certain circumstances.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our certificate of incorporation limits, to the maximum extent permitted by Delaware law, the
personal liability of our directors and officers for monetary damages. Our bylaws require us to
indemnify our directors and executive officers to the fullest extent not prohibited by Delaware law
or any other applicable law, and permit us to indemnify our other officers. A summary of the
circumstances in which such indemnification is provided for is contained herein, but that summary
is qualified in its entirety by reference to Article&nbsp;XI of our bylaws, incorporated by reference in
this registration statement.

<DIV style="font-family: 'Times New Roman',Times,serif">

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under our bylaws, we must generally advance all expenses incurred by our directors and
executive officers who are party or threatened to be made party to any action by reason of the fact
that each such director or executive officer is or was a director or executive officer of us. Each
advancement shall only be made if such director or executive officer undertakes to repay any such
advancement if it is ultimately determined that such person is not entitled to be indemnified under
our bylaws or otherwise. Our bylaws further provide that we may purchase indemnification insurance
on a person required or permitted to be indemnified under our bylaws.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have entered into indemnification agreements with each of our directors and certain
officers. These agreements, among other things, require us to indemnify each director and officer
to the fullest extent permitted by Delaware law, including indemnification for expenses such as
attorneys&#146; fees, judgments, fines and settlement amounts incurred by the director or officer in any
action or proceeding, including any action by or in the right of us, arising out of the person&#146;s
services as a director or officer of us, any subsidiary of us or any other company or enterprise to
which the person provides services at our request. We believe that our charter provisions and
indemnification agreements are necessary to attract and retain qualified persons as directors and
officers.

registrant&#146;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&#146;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

thereof.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Act 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 SEC 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.

of the filing of such reports and documents.
Item 4. Description of Securities.
Not applicable.
Item 5. Interest of Named Experts and Counsel.
None.
Item 6. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law provides generally that a corporation
shall have the power, and in some cases is required, to indemnify an agent, including an officer or
director, 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 or she
is or was a director, officer, employee or agent of the corporation, against certain expenses,
judgments, fines, settlements and other amounts under certain circumstances.
Our certificate of incorporation limits, to the maximum extent permitted by Delaware law, the
personal liability of our directors and officers for monetary damages. Our bylaws require us to
indemnify our directors and executive officers to the fullest extent not prohibited by Delaware law
or any other applicable law, and permit us to indemnify our other officers. A summary of the
circumstances in which such indemnification is provided for is contained herein, but that summary
is qualified in its entirety by reference to Article XI of our bylaws, incorporated by reference in
this registration statement.
Table of Contents
Under our bylaws, we must generally advance all expenses incurred by our directors and
executive officers who are party or threatened to be made party to any action by reason of the fact
that each such director or executive officer is or was a director or executive officer of us. Each
advancement shall only be made if such director or executive officer undertakes to repay any such
advancement if it is ultimately determined that such person is not entitled to be indemnified under
our bylaws or otherwise. Our bylaws further provide that we may purchase indemnification insurance
on a person required or permitted to be indemnified under our bylaws.
We have entered into indemnification agreements with each of our directors and certain
officers. These agreements, among other things, require us to indemnify each director and officer
to the fullest extent permitted by Delaware law, including indemnification for expenses such as
attorneys' fees, judgments, fines and settlement amounts incurred by the director or officer in any
action or proceeding, including any action by or in the right of us, arising out of the person's
services as a director or officer of us, any subsidiary of us or any other company or enterprise to
which the person provides services at our request. We believe that our charter provisions and
indemnification agreements are necessary to attract and retain qualified persons as 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:
(i)
To include any prospectus required by Section 10(a)(3) of the
Act;
(ii)
To reflect in the prospectus any facts or events arising after
the effective date of the 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 the 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 SEC 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 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 paragraphs (i) and (ii) of this section do not apply if the
Registration Statement is on Form S-8, and the information required to be included in a
post-effective amendment by those paragraphs is contained in reports filed with or furnished to the
SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the Registration Statement.
(2) That, for the purpose of determining any liability under the 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 this offering.
(4) That, for the purpose of determining liability of the registrant under the Act to any
purchaser in the initial distribution of the securities, the undersigned registrant undertakes that
in a primary offering of securities of the undersigned registrant pursuant to this Registration
Statement, regardless of the underwriting method used to sell the securities to the purchaser, if
the securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned registrant will be a seller to the purchaser and will be considered
to offer or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned
registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)
Any free writing prospectus relating to the offering prepared
by or on behalf of the undersigned registrant or used or referred to by the
undersigned registrant;
(iii)
The portion of any other free writing prospectus relating to
the offering containing material information about the undersigned registrant
or its securities provided by or on behalf of the undersigned registrant; and
(iv)
Any other communication that is an offer in the offering made
by the undersigned registrant to the purchaser.
Table of Contents
(5) That, for purposes of determining any liability under the 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.
Insofar as indemnification for liabilities arising under the Act 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 SEC 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.
