</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Under Arizona corporate law, in order for a corporation to indemnify a person who is or was a
director, a majority of the corporation&#146;s disinterested directors, special legal counsel, or the
shareholders must find that the conduct of the individual to be indemnified was in good faith and
that the individual reasonably believed that the conduct was in the corporation&#146;s best interests
(in the case of conduct in an &#147;official capacity&#148; with the corporation) or that the conduct was at
least not opposed to the corporation&#146;s best interests (in all other cases). In the case of any
criminal proceeding, the finding must be to the effect that the individual had no reasonable cause
to believe the conduct was unlawful. Indemnification is permitted with respect to expenses,
judgments, fines and amounts paid in settlement by such individuals, except that, in the case of a
proceeding by or in the right of the corporation, indemnification is limited to reasonable expenses
incurred in connection with the proceeding. However, a corporation cannot indemnify a director in
the cases noted in clause (ii)&nbsp;of the second sentence of the following paragraph. In addition, a
corporation&#146;s articles of incorporation may contain a provision permitting or making obligatory
indemnification of a director for liability to any person for any action taken or failure to act as
a director, except liability for (a)&nbsp;the amount of a financial benefit received by the director to
which the director is not entitled, (b)&nbsp;an intentional infliction of harm on the corporation or
shareholders, (c)&nbsp;a violation of the provisions of Arizona corporate law imposing liability for an
unlawful distribution, and (d)&nbsp;an intentional violation of criminal law.

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Indemnification under the Arizona corporate law is permissive, except in the event of a successful
defense, in which case, unless such indemnification is limited by the articles of incorporation, a
director or officer must be indemnified against reasonable expenses, including attorneys&#146; fees,
incurred in connection with the proceeding. In addition, Arizona corporate law requires Arizona
corporations to indemnify any &#147;outside director&#148; (a director who is not an officer, employee or
holder of more than five percent of any class of the corporation&#146;s stock or the stock of any
affiliate of the corporation) against liability unless (i)&nbsp;the corporation&#146;s articles of
incorporation limit such indemnification, (ii)&nbsp;the director is adjudged liable in a proceeding by
or in the right of the corporation or in any other proceeding charging improper financial benefit
to the director, whether or not involving action in the director&#146;s official capacity, in which the
director was adjudged liable on the basis that a financial benefit was improperly received by the
director, or (iii)&nbsp;a court determines, before payment to the outside director, that the director
failed to meet the standards of conduct described in the preceding paragraph. With certain
limitations, a court may also order that an individual be indemnified if the court finds that the
individual is fairly and reasonably entitled to indemnification in light of all of the relevant
circumstances, whether or not the individual has met the standards of conduct in this and the
preceding paragraph or was adjudged liable as described above.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">A corporation may indemnify an officer of the corporation who is a party to a proceeding because
the individual is or was an officer of the corporation to the same extent as a director. If the
individual is an officer, but not a director (or is also a director but the basis on which the
officer is made a party to the proceeding is an act or omission solely as an officer), the
corporation may indemnify the individual to the furthest extent provided by the articles of
incorporation, bylaws, a resolution of the board of directors, or contract, except for (a)
liability in connection with a proceeding by or in the right of the corporation other than for
reasonable expenses incurred in connection with the proceeding and (b)&nbsp;liability arising out of
conduct that constitutes (i)&nbsp;receipt by the officer of a financial benefit to which the officer is
not entitled, (ii)&nbsp;an intentional infliction of harm on the corporation or shareholders, or (iii)
an intentional violation of criminal law.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">In Arizona, a corporation may purchase and maintain insurance on behalf of a director or officer of
the corporation against liability asserted against or incurred by the individual arising from the
individual&#146;s status as a director or officer whether or not the corporation would have the power to
indemnify the individual against the same liability. We maintain insurance on a regular basis (and
not specifically in connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on our part out of
the foregoing indemnification provisions, subject to certain exclusions and to the policy limits.

(&#147;<U>Articles</U>&#148;) also provide for the indemnification of directors and officers. Article&nbsp;Sixth
of the Company&#146;s Articles provides that the
Company, to the maximum extent permitted by law, shall indemnify any individual who is or was a
party to or otherwise involved in any Proceeding because such individual is or was a director or
officer of the Company or, while a director or officer of the Company, is or was serving at the
request of the Company as a director, officer, partner, trustee, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against all Liability incurred by such individual in connection with such Proceeding.
The Articles define &#147;Proceeding&#148; to mean any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative and whether formal or
informal, including without limitation, any action, suit or proceeding by or in the right of the
Company and including any appeal of any such action, suit or proceeding. The Articles define
&#147;Liability&#148; to mean an obligation to pay a judgment, settlement, penalty or fine and reasonable
attorney&#146;s fees and all other costs and expenses reasonably related and incurred with respect to a
Proceeding.

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Indemnification provisions contained in a corporation&#146;s articles of incorporation, bylaws,
resolutions, contracts or otherwise will be valid only to the extent consistent with Arizona
corporate law described above. However if the articles of incorporation limit indemnification,
indemnification will be valid only to the extent consistent with the articles.

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&nbsp;percent change in the maximum
aggregate offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the

employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange Act) that is

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
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 of 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.

Item 4. Description of Securities
.
The Company's Common Stock, no par value, is registered pursuant to Section 12 of the Exchange Act,
and, therefore, the description of securities is omitted.
Item 5. Interests of Named Experts and Counsel
.
Not applicable.
Item 6. Indemnification of Directors and Officers
.
Under Arizona corporate law, in order for a corporation to indemnify a person who is or was a
director, a majority of the corporation's disinterested directors, special legal counsel, or the
shareholders must find that the conduct of the individual to be indemnified was in good faith and
that the individual reasonably believed that the conduct was in the corporation's best interests
(in the case of conduct in an "official capacity" with the corporation) or that the conduct was at
least not opposed to the corporation's best interests (in all other cases). In the case of any
criminal proceeding, the finding must be to the effect that the individual had no reasonable cause
to believe the conduct was unlawful. Indemnification is permitted with respect to expenses,
judgments, fines and amounts paid in settlement by such individuals, except that, in the case of a
proceeding by or in the right of the corporation, indemnification is limited to reasonable expenses
incurred in connection with the proceeding. However, a corporation cannot indemnify a director in
the cases noted in clause (ii) of the second sentence of the following paragraph. In addition, a
corporation's articles of incorporation may contain a provision permitting or making obligatory
indemnification of a director for liability to any person for any action taken or failure to act as
a director, except liability for (a) the amount of a financial benefit received by the director to
which the director is not entitled, (b) an intentional infliction of harm on the corporation or
shareholders, (c) a violation of the provisions of Arizona corporate law imposing liability for an
unlawful distribution, and (d) an intentional violation of criminal law.
Indemnification under the Arizona corporate law is permissive, except in the event of a successful
defense, in which case, unless such indemnification is limited by the articles of incorporation, a
director or officer must be indemnified against reasonable expenses, including attorneys' fees,
incurred in connection with the proceeding. In addition, Arizona corporate law requires Arizona
corporations to indemnify any "outside director" (a director who is not an officer, employee or
holder of more than five percent of any class of the corporation's stock or the stock of any
affiliate of the corporation) against liability unless (i) the corporation's articles of
incorporation limit such indemnification, (ii) the director is adjudged liable in a proceeding by
or in the right of the corporation or in any other proceeding charging improper financial benefit
to the director, whether or not involving action in the director's official capacity, in which the
director was adjudged liable on the basis that a financial benefit was improperly received by the
director, or (iii) a court determines, before payment to the outside director, that the director
failed to meet the standards of conduct described in the preceding paragraph. With certain
limitations, a court may also order that an individual be indemnified if the court finds that the
individual is fairly and reasonably entitled to indemnification in light of all of the relevant
circumstances, whether or not the individual has met the standards of conduct in this and the
preceding paragraph or was adjudged liable as described above.
A corporation may indemnify an officer of the corporation who is a party to a proceeding because
the individual is or was an officer of the corporation to the same extent as a director. If the
individual is an officer, but not a director (or is also a director but the basis on which the
officer is made a party to the proceeding is an act or omission solely as an officer), the
corporation may indemnify the individual to the furthest extent provided by the articles of
incorporation, bylaws, a resolution of the board of directors, or contract, except for (a)
liability in connection with a proceeding by or in the right of the corporation other than for
reasonable expenses incurred in connection with the proceeding and (b) liability arising out of
conduct that constitutes (i) receipt by the officer of a financial benefit to which the officer is
not entitled, (ii) an intentional infliction of harm on the corporation or shareholders, or (iii)
an intentional violation of criminal law.
In Arizona, a corporation may purchase and maintain insurance on behalf of a director or officer of
the corporation against liability asserted against or incurred by the individual arising from the
individual's status as a director or officer whether or not the corporation would have the power to
indemnify the individual against the same liability. We maintain insurance on a regular basis (and
not specifically in connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on our part out of
the foregoing indemnification provisions, subject to certain exclusions and to the policy limits.
In addition to the foregoing, the Company's Amended and Restated Articles of Incorporation
("
Articles
") also provide for the indemnification of directors and officers. Article Sixth
of the Company's Articles provides that the
Company, to the maximum extent permitted by law, shall indemnify any individual who is or was a
party to or otherwise involved in any Proceeding because such individual is or was a director or
officer of the Company or, while a director or officer of the Company, is or was serving at the
request of the Company as a director, officer, partner, trustee, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against all Liability incurred by such individual in connection with such Proceeding.
The Articles define "Proceeding" to mean any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative and whether formal or
informal, including without limitation, any action, suit or proceeding by or in the right of the
Company and including any appeal of any such action, suit or proceeding. The Articles define
"Liability" to mean an obligation to pay a judgment, settlement, penalty or fine and reasonable
attorney's fees and all other costs and expenses reasonably related and incurred with respect to a
Proceeding.
Indemnification provisions contained in a corporation's articles of incorporation, bylaws,
resolutions, contracts or otherwise will be valid only to the extent consistent with Arizona
corporate law described above. However if the articles of incorporation limit indemnification,
indemnification will be valid only to the extent consistent with the articles.

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 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) of this section do not apply if the
Registration Statement is on Form S-8, and 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.
(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 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 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
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 of 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.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has
