    <TD>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 Act
and will be governed by the final adjudication of such issue.</TD>

Articles of Incorporation and the agreements are subject to the limitations set forth by California
law.
ITEM 7. Exemption From Registration Claimed
Not applicable.
ITEM 8. Exhibits
Reference is made to the Exhibit Index.
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 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;
(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) of this section 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 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 that 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 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.
(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 Act
and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it
has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and
has duly caused this Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Glendale, State of California, on the 4th day of
November, 2005.
