Corporation Law of the State of Delaware, as the same exists or may hereafter
be amended (the &#147;General Corporation Law&#148;), inter alia, provides that a
Delaware corporation may indemnify any persons who were, are or are threatened
to be made, parties 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 such corporation), by reason of the fact
that such person is or was an officer, director, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys&#146; fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding, provided such person acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the corporation&#146;s best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was
illegal.&#160; In addition, the statutes of
Delaware contain provisions to the general effect that any director shall in
the performance of his duties be fully protected in relying in good faith upon
the books of account or records of the corporation or statements prepared by
any official of the corporation.</font></p>

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.&#160; 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.</p>

Item 6.
Indemnification of Directors and
Officers.
The Company is incorporated under the laws of
the State of Delaware. Section 145 ("Section 145") of the General
Corporation Law of the State of Delaware, as the same exists or may hereafter
be amended (the "General Corporation Law"), inter alia, provides that a
Delaware corporation may indemnify any persons who were, are or are threatened
to be made, parties 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 such corporation), by reason of the fact
that such person is or was an officer, director, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding, provided such person acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the corporation's best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was
illegal.  In addition, the statutes of
Delaware contain provisions to the general effect that any director shall in
the performance of his duties be fully protected in relying in good faith upon
the books of account or records of the corporation or statements prepared by
any official of the corporation.
Section 145 further authorizes a
corporation to purchase and maintain insurance on behalf of any person who 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 or enterprise, against any liability asserted
against him and incurred by him in any such
2
capacity, arising out of his status as such, whether or not the
corporation would otherwise have the power to indemnify him under Section 145.
In accordance with the General Corporation Law of
the State of Delaware, Article VII of the Company's Amended and Restated
Certificate of Incorporation (the "Certificate") provides that no director of
the Company shall be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii) in
respect of certain unlawful dividend payments or stock redemptions or
repurchases, or (iv) for any transaction from which the director derived
an improper personal benefit.  In
addition, the Certificate provides that if the General Corporation Law of the
State of Delaware is amended to authorize the further elimination or limitation
of the liability of directors, then the liability of a director of the
Corporation shall be eliminated or limited to the fullest extent permitted by
the General Corporation Law of the State of Delaware, as so amended.
Article V of the Company's Amended and Restated
By-laws provides for indemnification, to the fullest extent authorized by the
General Corporation Law of the State of Delaware (as the same exists or may
hereafter be amended; provided that no such amendment shall reduce the level of
indemnity provided prior to such amendment), by the Company of its directors,
officers and certain non-officer employees under certain circumstances against
expenses (including, among other things, attorneys' fees, judgments, fines,
taxes, penalties and amounts reasonably paid in settlement) reasonably incurred
in connection with the defense or settlement of any threatened, pending or
completed legal proceeding (or any claim, issue or matter therein) in which any
such person is involved by reason of the fact that such person is or was a
director, officer or employee of the Company if such person 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 Company, and, with respect to criminal actions or
proceedings, if such person had no reasonable cause to believe his or her
conduct was unlawful.
The Company also carries standard directors' and
officers' liability insurance covering its directors and officers.

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:
(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.
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 a prospectus filed with the Commission pursuant to Rule 424(b) if,
in the aggregate, the changes in volume and price represent no more than 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 the registration statement or any material change to such
information in the registration statement;
provided, however
,
that paragraphs (a)(1)(i) and (a)(1)(ii) above shall 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 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 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 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
