<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is incorporated under the laws of the State of Delaware. Sections 102 and 145 of the Delaware General Corporation Law (the "DGCL") set
forth the conditions and limitations governing the indemnification of officers, directors and other persons by Delaware corporations. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generally,
Section&nbsp;145 of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to
any action, suit or proceeding (except actions by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against
all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such </FONT></P>

action, suit or proceeding 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 corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In addition, a Delaware corporation may similarly indemnify such person for expenses actually and reasonably
incurred by him or her in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided
that the
Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall have determined upon application, that, despite the adjudication of liability by in view of all
of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper. To the extent that a present or former director or
officer of a Delaware corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, such
person shall be indemnified against expenses actually and reasonably incurred by such person in connection therewith. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generally,
Section&nbsp;102(b)(7) of the DGCL provides that the certificate of incorporation of a Delaware corporation may contain provisions eliminating or limiting the personal
liability of a director to a corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; provided that such provision may not eliminate or limit the liability of a
director (i)&nbsp;for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct
or knowing violation of law, (iii)&nbsp;under Section&nbsp;174 of Title 8 of the DGCL or (iv)&nbsp;for any transaction from which the director derived an improper personal benefit. No such
provision may eliminate or limit the liability of a director for any act or omission occurring prior to the date which such provisions became effective. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145
of the DGCL provides that a Delaware corporation shall have the power to purchase and maintain insurance of behalf of any person who is or was a director, officer,
employee or agent of the corporation against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not
the corporation would have the power to indemnify such person against the same pursuant to the provisions of the DGCL. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our
certificate of incorporation, as amended, provides for indemnification of directors and officers for liabilities and expenses incurred in defending actions brought against them in
such capacities. Our certificate of incorporation provides that we shall indemnify our directors and officers to the maximum extent now or hereafter permitted by law. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
maintain directors' and officers' liability insurance covering all of our directors and officers against claims arising out of the performance of their duties. </FONT></P>

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&nbsp;424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in

for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section&nbsp;13(a) or Section&nbsp;15(d) of the

as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions
described under Item 6 above, 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. </FONT></P>

ITEM 6.    INDEMNIFICATION OF DIRECTORS AND OFFICERS.
The Company is incorporated under the laws of the State of Delaware. Sections 102 and 145 of the Delaware General Corporation Law (the "DGCL") set
forth the conditions and limitations governing the indemnification of officers, directors and other persons by Delaware corporations.
Generally,
Section 145 of the DGCL provides that a Delaware corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to
any action, suit or proceeding (except actions by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation against
all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such
II-1
action, suit or proceeding 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 corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In addition, a Delaware corporation may similarly indemnify such person for expenses actually and reasonably
incurred by him or her in connection with the defense or settlement of any action or suit by or in the right of the corporation, provided such person acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the corporation, and, in the case of claims, issues and matters as to which such person shall have been adjudged liable to the corporation, provided
that the
Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall have determined upon application, that, despite the adjudication of liability by in view of all
of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper. To the extent that a present or former director or
officer of a Delaware corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, such
person shall be indemnified against expenses actually and reasonably incurred by such person in connection therewith.
Generally,
Section 102(b)(7) of the DGCL provides that the certificate of incorporation of a Delaware corporation may contain provisions eliminating or limiting the personal
liability of a director to a corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; provided that such provision may not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct
or knowing violation of law, (iii) under Section 174 of Title 8 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit. No such
provision may eliminate or limit the liability of a director for any act or omission occurring prior to the date which such provisions became effective.
Section 145
of the DGCL provides that a Delaware corporation shall have the power to purchase and maintain insurance of behalf of any person who is or was a director, officer,
employee or agent of the corporation against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not
the corporation would have the power to indemnify such person against the same pursuant to the provisions of the DGCL.
Our
certificate of incorporation, as amended, provides for indemnification of directors and officers for liabilities and expenses incurred in defending actions brought against them in
such capacities. Our certificate of incorporation provides that we shall indemnify our directors and officers to the maximum extent now or hereafter permitted by law.
We
maintain directors' and officers' liability insurance covering all of our directors and officers against claims arising out of the performance of their duties.

ITEM 9.    UNDERTAKINGS.
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 of 1933;
(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 prospectus filed with the Commission pursuant to Rule 424(b) 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; or
(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 if the information required to be included in a post-effective
amendment by paragraphs (1)(i) and (ii) above is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement, then paragraphs (1)(i) and (ii) shall not apply.
2.    That,
for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities
II-3
offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and
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.
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 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.
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 provisions
described under Item 6 above, 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.
