</DIV>


<DIV align="justify" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law authorizes a court to award, or a
corporation&#146;s board of directors to grant, indemnity to officers, directors and other corporate
agents in terms sufficiently broad to permit such indemnification under certain circumstances and
subject to certain limitations.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Registrant&#146;s certificate of incorporation and bylaws provide that Registrant shall indemnify
its directors, officers, employees and agents to the full extent permitted by Delaware General
Corporation Law, including in circumstances in which indemnification is otherwise discretionary
under Delaware law.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, Registrant has entered into separate indemnification agreements with its
directors, officers and certain employees which require Registrant, among other things, to
indemnify them against certain liabilities which may arise by reason of their status as directors,
officers or certain other employees. Registrant also intends to maintain director and officer
liability insurance, if available on reasonable terms.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These indemnification provisions and the indemnification agreements entered into between
Registrant and its officers and directors may be sufficiently broad to permit indemnification of
Registrant&#146;s officers and directors for liabilities (including reimbursement of expenses incurred)
arising under the Securities Act.

Table of Contents
All documents subsequently filed by Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d)
of the Exchange Act, prior to the filing of a post-effective amendment which indicates that all
securities offered have been sold or which deregisters all securities then remaining unsold, shall

reference herein modifies or supersedes such earlier statement. Any statement so modified or
superseded shall not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.
Item 6.
Indemnification of Directors and Officers
.
Section 145 of the Delaware General Corporation Law authorizes a court to award, or a
corporation's board of directors to grant, indemnity to officers, directors and other corporate
agents in terms sufficiently broad to permit such indemnification under certain circumstances and
subject to certain limitations.
Registrant's certificate of incorporation and bylaws provide that Registrant shall indemnify
its directors, officers, employees and agents to the full extent permitted by Delaware General
Corporation Law, including in circumstances in which indemnification is otherwise discretionary
under Delaware law.
In addition, Registrant has entered into separate indemnification agreements with its
directors, officers and certain employees which require Registrant, among other things, to
indemnify them against certain liabilities which may arise by reason of their status as directors,
officers or certain other employees. Registrant also intends to maintain director and officer
liability insurance, if available on reasonable terms.
These indemnification provisions and the indemnification agreements entered into between
Registrant and its officers and directors may be sufficiently broad to permit indemnification of
Registrant's officers and directors for liabilities (including reimbursement of expenses incurred)
arising under the Securities Act.

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 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;
II-2
Table of Contents
(iii)     to include any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to the information in the
Registration Statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above 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 to the Commission by 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 Securities Act, each
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 Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Securities 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.
(c)     Insofar as indemnification for liabilities arising under the Securities Act may be permitted to
directors, officers and controlling persons of Registrant pursuant to the foregoing provisions, or
otherwise, Registrant has been advised that in the opinion of the Securities and Exchange
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 Registrant of expenses incurred or paid by a director, officer or
controlling person of 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, 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.
