<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s Common Stock to be so offered is registered under Section
12(b) of the Securities Exchange Act.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is incorporated under the laws of the State of Delaware.
Reference is made to Section&nbsp;145 of the Delaware General Corporation Law, or
DGCL, which generally provides that all directors and officers (as well as
other employees and individuals) may be indemnified against expenses (including
attorney&#146;s fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with certain specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation &#151; a &#147;derivative action&#148;),
if they acted in


<P align="center" style="font-size: 10pt">&nbsp;

<H5 align="left" style="page-break-before:always">&nbsp;</H5><P>

<DIV style="font-family: 'Times New Roman',Times,serif">
<P align="left" style="font-size: 10pt">good faith and in a manner they 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 their conduct
was unlawful. A similar standard of care is applicable in the case of
derivative actions, except that indemnification extends only to expenses
(including attorneys&#146; fees) actually and reasonably incurred in connection with
defense or settlement of an action and the DGCL requires court approval before
there can be any indemnification where the person seeking indemnification has
been found liable to the corporation. Section&nbsp;145 of the DGCL also provides
that the rights conferred thereby are not exclusive of any other right which
any person may be entitled to under any bylaw, agreement, vote of stockholders
or disinterested directors or otherwise, and permits a corporation to advance
expenses to or on behalf of a person to be indemnified upon receipt of an
undertaking to repay the amounts advanced if it is determined that the person
is not entitled to be indemnified.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s bylaws provide that each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding by reason of the fact that he is or was a director or officer of the
Company (or is or was serving at the request of the Registrant as a director,
officer, employee or agent of another entity), shall be indemnified and held
harmless by the Company to the fullest extent authorized by the DGCL, as in
effect (or to the extent that indemnification is broadened, as it may be
amended), against all expense, liability and loss (including attorneys&#146; fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be
paid in settlement) reasonably incurred or suffered by such person in
connection therewith. Except with respect to actions initiated by an officer
or director against the Company to recover the amount of an unpaid claim, the
Company is required to indemnify an officer or director in connection with an
action, suit or proceeding initiated by such person only if such action, suit
or proceeding was authorized by the board of directors of the Company. The
bylaws of the Company further provide that an officer or director may (60&nbsp;days
after a written claim has been received by the Registrant) bring suit against
the Registrant to recover an unpaid claim and, if such suit is successful, the
expense of bringing such suit. While it is a defense to such suit that the
claimant has not met the applicable standards of conduct which make
indemnification permissible under the DGCL, neither the failure of the board of
directors to have made a determination that indemnification is proper, nor an
actual determination that the claimant has not met the applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The bylaws of the Company also provide that the rights conferred thereby
are contract rights, that they are not exclusive of any other rights which an
officer or director may have or hereafter acquire under any statute, any other
provision of the certificate of incorporation, bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, and that they include the
right to be paid by the Company the expenses incurred in defending any
specified action, suit or proceeding in advance of its final disposition
provided that, if the DGCL so requires, such payment shall only be made upon
delivery to the Company by the officer or director of an undertaking to repay
all amounts so advanced if it shall ultimately be determined that such director
or officer is not entitled to be indemnified under the bylaws or otherwise.

Registrant&#146;s annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan&#146;s annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 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.

Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act (other than the
portions of those documents not deemed to be filed), subsequent to the date
hereof and prior to the filing of a post-effective amendment hereto indicating
that all the shares of the Company's Common Stock offered hereunder have been
sold or which deregisters all the shares of the Company's Common Stock then
remaining unsold, shall be deemed to be incorporated by reference into this
Registration Statement and to be a part hereof from the date of filing of such
documents. Any statement contained in a document incorporated or deemed to be
incorporated by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or in any other subsequently filed document which also is or
is deemed to be incorporated by reference herein modifies or supersedes such
statement. Any statement so modified or superseded shall not be deemed, except
as so modified or superseded, to constitute a part of the Registration
Statement.
Item 4. Description of Securities.
The Company's Common Stock to be so offered is registered under Section
12(b) of the Securities Exchange Act.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Company is incorporated under the laws of the State of Delaware.
Reference is made to Section 145 of the Delaware General Corporation Law, or
DGCL, which generally provides that all directors and officers (as well as
other employees and individuals) may be indemnified against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with certain specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation — a "derivative action"),
if they acted in
good faith and in a manner they 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 their conduct
was unlawful. A similar standard of care is applicable in the case of
derivative actions, except that indemnification extends only to expenses
(including attorneys' fees) actually and reasonably incurred in connection with
defense or settlement of an action and the DGCL requires court approval before
there can be any indemnification where the person seeking indemnification has
been found liable to the corporation. Section 145 of the DGCL also provides
that the rights conferred thereby are not exclusive of any other right which
any person may be entitled to under any bylaw, agreement, vote of stockholders
or disinterested directors or otherwise, and permits a corporation to advance
expenses to or on behalf of a person to be indemnified upon receipt of an
undertaking to repay the amounts advanced if it is determined that the person
is not entitled to be indemnified.
The Company's bylaws provide that each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding by reason of the fact that he is or was a director or officer of the
Company (or is or was serving at the request of the Registrant as a director,
officer, employee or agent of another entity), shall be indemnified and held
harmless by the Company to the fullest extent authorized by the DGCL, as in
effect (or to the extent that indemnification is broadened, as it may be
amended), against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be
paid in settlement) reasonably incurred or suffered by such person in
connection therewith. Except with respect to actions initiated by an officer
or director against the Company to recover the amount of an unpaid claim, the
Company is required to indemnify an officer or director in connection with an
action, suit or proceeding initiated by such person only if such action, suit
or proceeding was authorized by the board of directors of the Company. The
bylaws of the Company further provide that an officer or director may (60 days
after a written claim has been received by the Registrant) bring suit against
the Registrant to recover an unpaid claim and, if such suit is successful, the
expense of bringing such suit. While it is a defense to such suit that the
claimant has not met the applicable standards of conduct which make
indemnification permissible under the DGCL, neither the failure of the board of
directors to have made a determination that indemnification is proper, nor an
actual determination that the claimant has not met the applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.
The bylaws of the Company also provide that the rights conferred thereby
are contract rights, that they are not exclusive of any other rights which an
officer or director may have or hereafter acquire under any statute, any other
provision of the certificate of incorporation, bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, and that they include the
right to be paid by the Company the expenses incurred in defending any
specified action, suit or proceeding in advance of its final disposition
provided that, if the DGCL so requires, such payment shall only be made upon
delivery to the Company by the officer or director of an undertaking to repay
all amounts so advanced if it shall ultimately be determined that such director
or officer is not entitled to be indemnified under the bylaws or otherwise.
Item 7. Exemption from Registration Claimed.
Not Applicable.
Item 8. Exhibits.
The Exhibit Index included herein is hereby incorporated by reference.
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 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 forgoing, any increase or decrease in
volume of securities offered
(if the total dollar value of securities offered would not
exceed that which is registered) and deviation from the low
or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the
Securities and Exchange Commission pursuant to Rule 424(b)
under the Securities Act of 1933 if, in the aggregate, the
changes in volume and price represents 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;
(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) do not apply
if the registration statement is on Form S-3, Form S-8 or Form F-3, and 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 section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.
(2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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 of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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 of 1933 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 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.
