that a corporation has the power to indemnify a director, officer, employee or
agent of the corporation and certain other persons serving at the request of
the corporation in related capacities against amounts paid and expenses
incurred in connection with an action or proceeding to which he is or is
threatened to be made a party by reason of such position, if such person shall

has been successful, on the merits or otherwise, including the dismissal of an
action without prejudice, he or she is required to be indemnified by the
registrant against all expenses (including attorneys&#146; fees) incurred in
connection therewith. Expenses shall be advanced to a director or officer at
his or her request, provided that he or she undertakes to repay the amount
advanced if it is ultimately determined that he or she is not entitled to

been met. In the event of a determination by the registrant that the director
or officer did not meet the applicable standard of conduct required for
indemnification, or if the registrant fails to make an indemnification payment
within sixty days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the registrant
notice of the action for which indemnity is sought and the registrant has the
right to participate in such action or assume the defense thereof.</font></p>

must indemnify those persons to fullest extent permitted by such law as so
amended.</font></p>

registrant of expenses incurred or paid by a director, officer or 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.</font></p>

Item 5.   Interests of Named
Experts and Counsel
Cooley LLP has opined as to the legality of the shares of common stock
being offered by this registration statement on Form S-8.
Item 6. Indemnification of Directors and Officers.
Section 102 of the Delaware General Corporation Law allows a
corporation to eliminate the personal liability of directors of a corporation
to the corporation or its stockholders for monetary damages for a breach of
fiduciary duty as a director, except where the director breached his duty of
loyalty, failed to act in good faith, engaged in intentional misconduct or
knowingly violated a law, authorized the payment of a dividend or approved a
stock repurchase in
1
violation of Delaware corporate law or obtained an improper personal
benefit. The registrant has included such a provision in its Certificate of
Incorporation, as amended (the "Certificate of Incorporation").
Section 145 of the General Corporation Law of Delaware provides
that a corporation has the power to indemnify a director, officer, employee or
agent of the corporation and certain other persons serving at the request of
the corporation in related capacities against amounts paid and expenses
incurred in connection with an action or proceeding to which he is or is
threatened to be made a party by reason of such position, if such person shall
have 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, in any criminal
proceeding, if such person had no reasonable cause to believe his conduct was
unlawful; provided that, in the case of actions brought by or in the right of
the corporation, no indemnification shall be made with respect to any matter as
to which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.
Article SEVENTH of the Certificate of Incorporation provides that
no director of the registrant shall be personally liable for any monetary
damages for any breach of fiduciary duty as a director, except to the extent
that the Delaware General Corporation Law prohibits the elimination or
limitation of liability of directors for breach of fiduciary duty.
Article EIGHTH of the Certificate of Incorporation provides that a
director or officer of the registrant shall be indemnified by the registrant
against:
(a)           all expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
incurred in connection with any litigation or other legal proceeding (other
than an action by or in the right of the registrant) brought against him or her
by virtue of his or her position as a director or officer of the registrant if
he or she acted in good faith and in a manner he or she reasonably believed to
be in, or not opposed to, the best interests of the registrant, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful; and
(b)           all expenses
(including attorneys' fees) and amounts paid in the settlement incurred in
connection with any action by or in the right of the registrant brought against
him or her by virtue of his or her position as a director or officer of the
registrant if he or she acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
registrant, unless a court determines that, despite such adjudication but in
view of all of the circumstances, he or she is entitled to indemnification of
such expenses.
Notwithstanding the foregoing, to the extent that a director or officer
has been successful, on the merits or otherwise, including the dismissal of an
action without prejudice, he or she is required to be indemnified by the
registrant against all expenses (including attorneys' fees) incurred in
connection therewith. Expenses shall be advanced to a director or officer at
his or her request, provided that he or she undertakes to repay the amount
advanced if it is ultimately determined that he or she is not entitled to
indemnification for such expenses.
Indemnification is required to be made unless the registrant determines
that the applicable standard of conduct required for indemnification has not
been met. In the event of a determination by the registrant that the director
or officer did not meet the applicable standard of conduct required for
indemnification, or if the registrant fails to make an indemnification payment
within sixty days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the registrant
notice of the action for which indemnity is sought and the registrant has the
right to participate in such action or assume the defense thereof.
Article EIGHTH of the Certificate of Incorporation further
provides that the indemnification provided therein is not exclusive, and
provides that in the event that the Delaware General Corporation Law is amended
to expand the indemnification permitted to directors or officers the registrant
must indemnify those persons to fullest extent permitted by such law as so
amended.
2
The registrant has purchased directors' and officers' liability
insurance which would indemnify its directors and officers against damages
arising out of certain kinds of claims which might be made against them based
on their negligent acts or omissions while acting in their capacity as such.

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.
(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 such information in the
registration statement;
provided, however,
that paragraphs (a)(i) and
(a)(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
3
reports filed with or furnished to the Securities and Exchange
Commission by the registrant pursuant to section 13 or section 15(d) of
the Exchange Act that are incorporated by reference in the registration
statement.
(b)
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 herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
(c)
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.
2.
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 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 herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
3.
Insofar as indemnification
for liabilities arising under the Securities 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 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 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.
