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.</P>

Description of Securities.

Item 5.

Item 6.
Indemnification of Directors and Officers.
Section 102 of the Delaware General Corporation
Law permits a corporation to eliminate the personal liability of its directors or its stockholders for monetary damages for a breach
of fiduciary duty as a director, except where the director breached his or her 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 violation
of Delaware corporate law or obtained an improper personal benefit.  The registrant's certificate of incorporation provides
that no director shall be personally liable to the registrant or its stockholders for monetary damages for any breach of fiduciary
duty as a director, notwithstanding any provision of law imposing such liability, except to the extent that the Delaware General
Corporation Law prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.
Section 145 of the Delaware General Corporation
Law 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 expenses (including attorneys' fees),
judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit
or proceeding to which he or she is or is threatened to be made a party by reason of such position, 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 corporation, and, in any
criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of
actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter
as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of
Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other
court shall deem proper.
The registrant's certificate of incorporation
and by-laws provide that the registrant will, to the fullest extent permitted by Section 145 of the Delaware General Corporation
Law, indemnify each person 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 by reason of the fact that he is or was, or has agreed
to become, a director or officer of the registrant, or is or was serving, or has agreed to serve, at the registrant's request
as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such
capacity, against all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom. 
The right to indemnification does not apply to any proceeding initiated by such persons unless the initiation of the proceeding
was approved by the registrant's board of directors.
The registrant maintains a general liability
insurance policy which covers certain liabilities of its directors and officers of the registrant arising out of claims based on
acts or omissions in their capacities as directors or officers.
The registrant has generally entered into indemnification
agreements with its directors and officers.  These indemnification agreements require the registrant, among other things,
to indemnify its directors and officers for certain expenses (including attorneys' fees), judgments, fines, penalties and
settlement amounts, actually and reasonably incurred by a director or officer in any action or proceeding arising out of his service
as one of the registrant's directors or officers, or as a director, partner, trustee, officer, employee or agent of another
entity at the registrant's request.
Item 7.
Exemption from Registration Claimed.
Not applicable.
Item 8.
Exhibits.
The Exhibit Index immediately preceding
the exhibits is incorporated herein by reference.
Item 9.
Undertakings.
1.
Item 512(a) of Regulation S-K
. 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; 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 (i) and (ii)
do not apply if 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 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 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.
2.
Item 512(b) of Regulation S-K
. 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 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.
3.
Item 512(h) of Regulation S-K
. 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.
