<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;6. Indemnification of Directors and Officers</B>
</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 makes provision for the indemnification of
officers and directors in terms sufficiently broad to include indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred) arising under the
Securities Act. Section&nbsp;145 of the Delaware General Corporation Law permits indemnification by the
corporation of its officers and directors against expenses (including attorneys&#146; fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by them in connection with
actions or proceedings against them if they acted in good faith and in a manner they 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 their conduct was unlawful. Section&nbsp;145
provides that no indemnification may be made, however, without court approval, in respect of any
claim as to which the officer or director is adjudged to be liable to the corporation. Such
indemnification provisions of Delaware law are expressly not exclusive of any other rights which
the officers or directors may have under the corporation&#146;s by-laws or agreements, pursuant to the
vote of stockholders or disinterested directors or otherwise.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Certificate of Incorporation, as amended, of the Registrant provides that the
Registrant will, to the maximum extent permitted by law, indemnify each of its officers and
directors against expenses, judgments, fines, settlements and other amounts actually and reasonably
incurred in connection with any proceeding arising by reason of the fact any such person is or was
a director or officer of the Registrant. The Registrant also carries directors and officers
liability insurance.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant has entered into separate indemnification agreements with its directors and
officers. These agreements require the Registrant, among other things, to indemnify them against
liabilities that may arise by reason of their status or service as directors or officers (other
than liabilities arising from actions not taken in good faith or in a manner the indemnitee
believed to be opposed to the best interests of the Registrant), and to advance their expenses
incurred as a result of any proceeding against them as to which they could be indemnified. Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors,
officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant
has been informed that in the opinion of the Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

Item 6. Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law makes provision for the indemnification of
officers and directors in terms sufficiently broad to include indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred) arising under the
Securities Act. Section 145 of the Delaware General Corporation Law permits indemnification by the
corporation of its officers and directors against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by them in connection with
actions or proceedings against them if they acted in good faith and in a manner they 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 their conduct was unlawful. Section 145
provides that no indemnification may be made, however, without court approval, in respect of any
claim as to which the officer or director is adjudged to be liable to the corporation. Such
indemnification provisions of Delaware law are expressly not exclusive of any other rights which
the officers or directors may have under the corporation's by-laws or agreements, pursuant to the
vote of stockholders or disinterested directors or otherwise.
The Certificate of Incorporation, as amended, of the Registrant provides that the
Registrant will, to the maximum extent permitted by law, indemnify each of its officers and
directors against expenses, judgments, fines, settlements and other amounts actually and reasonably
incurred in connection with any proceeding arising by reason of the fact any such person is or was
a director or officer of the Registrant. The Registrant also carries directors and officers
liability insurance.
The Registrant has entered into separate indemnification agreements with its directors and
officers. These agreements require the Registrant, among other things, to indemnify them against
liabilities that may arise by reason of their status or service as directors or officers (other
than liabilities arising from actions not taken in good faith or in a manner the indemnitee
believed to be opposed to the best interests of the Registrant), and to advance their expenses
incurred as a result of any proceeding against them as to which they could be indemnified. Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors,
officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant
has been informed that in the opinion of the Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.
Item 7. Exemption from Registration Claimed
Not applicable.
Item 8. Exhibits
See the attached Exhibit Index at page 9, which is incorporated herein by reference.
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:
4
Table of Contents
(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) under the Securities Act 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 "Calculation of Registration Fee" table in
the effective 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) 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
Commission by the Registrant pursuant to Section 13 or 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.
(b) The undersigned 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 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.
(h) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, executive officers and controlling persons of the Registrant pursuant to
the provisions described in Item 6 above, or otherwise, 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,
5
Table of Contents
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.
