Van Kasper & Company
As Representative of the several
Underwriters named in Schedule A hereto
600 California Street, 17th Floor
San Francisco, CA 94111
 
Ladies and Gentlemen:
 
     AMERCO, a Nevada corporation (the "Company"), and Paul F. Shoen (the
"Selling Stockholder"), confirm their agreements with Van Kasper & Company, the
representative of the several underwriters named in Schedule A hereto
(collectively, the "Underwriters," which term shall also include any underwriter
substituted as hereinafter provided in Section 10), with respect to the sale by
the Selling Stockholder and the purchase by the Underwriters, acting severally
and not jointly, of the respective numbers of shares totaling 500,000 shares of
Common Stock, par value $.25 per share (the "Shares"), of the Company set forth
in said Schedule A.
 
     You have advised us that each of you, acting severally and not jointly,
desire to purchase the Shares and that you have been authorized by the other
Underwriters to execute this Agreement on their behalf.
 
     The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (File No.
33-      ) covering the registration of the Shares under the Securities Act of
1933, as amended (the "1933 Act"), including the related preliminary prospectus,
and either (A) has prepared and proposes to file, prior to the effective date of
such registration statement, one or more amendments to such registration
statement, including a final prospectus, or (B) if the Company has elected to
rely upon Rule 430A ("Rule 430A") of the rules and regulations of the Commission
under the 1933 Act (the "1933 Act Regulations"), will prepare and file a
prospectus, in accordance with the provisions of Rule 430A and Rule 424(b)
("Rule 424(b)") of the 1933 Act Regulations, promptly after execution and
delivery of this Agreement. The information, if any, included in such prospectus
that was omitted from any prospectus included in such registration statement at
the time it becomes effective but that is deemed, pursuant to Rule 430A(b), to
be part of such registration statement at the time it becomes effective is
referred to herein as the "Rule 430A Information." Each form of prospectus used
before the time such registration statement becomes effective is herein called a
"preliminary prospectus." Such registration statement, including the exhibits
thereto, as amended at the time it becomes effective and including, if
applicable, the Rule 430A Information, is herein called the "Registration
Statement," and the form of prospectus included in the Registration Statement at
the time it becomes effective is herein called the "Prospectus" except that, if
the final Prospectus first furnished to the Underwriters after the execution of
this Agreement in connection with the offering of the Shares differs from the
prospectus included in the Registration Statement at the time it becomes
effective (whether or not such prospectus is required to be filed pursuant to
Rule 424(b)), the term "Prospectus," shall refer to the final Prospectus first
furnished to the Underwriters for such use. Any reference herein to the
Registration Statement, any preliminary prospectus or the Prospectus shall be
deemed to refer to and include the documents incorporated by reference therein
pursuant to Item 12 of Form S-3 under the 1933 Act, as of the date thereof, and
any reference herein to the terms "amend," "amendment" or "supplement" with
respect to any preliminary prospectus or the Prospectus shall be deemed to refer
to and include any documents filed with the Commission after such date under the
Securities Exchange Act of 1934, as amended (the "1934 Act"), and the rules and
regulations of the Commission promulgated thereunder (the "1934 Act
Regulations"), and so incorporated by reference (all such incorporated documents
being herein called the "Incorporated Documents").
   3
 
     The Company and the Selling Stockholder understand that the Underwriters
propose to make a public offering of the Shares as soon as you deem advisable
after the Registration Statement becomes effective.
 
SECTION 1.  REPRESENTATIONS AND WARRANTIES.
 
     (a) The Company represents and warrants to and agrees with each of the
Underwriters that:
 
     (i) The Registration Statement relating to the Shares, including such
amendments to such Registration Statement as may have been required to the date
of this Agreement, has been prepared by the Company under and in conformity with
the provisions of the 1933 Act and the 1933 Act Regulations thereunder, and has
been filed with the Commission. If such Registration Statement has not become
effective upon execution of this Agreement, a further amendment to such
Registration Statement, including a form of Prospectus, necessary to permit such
Registration Statement to become effective will promptly be filed by the Company
with the Commission. If such Registration Statement has become effective, a
Prospectus containing information permitted to be omitted at the time of
effectiveness by Rule 430A of the 1933 Act Regulations will promptly be filed by
the Company with the Commission in accordance with Rule 424 of the 1933 Act
Regulations (and in form and substance reasonably satisfactory to the counsel
for the Underwriters). When the Registration Statement and any further
amendments thereto shall become effective, (A) the Registration Statement and
any such amendments will comply in all material respects with the requirements
of the 1933 Act and the 1933 Act Regulations; (B) neither the Registration
Statement nor any such amendment will contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading. Neither the Prospectus nor any
amendment or supplement thereto will, as of their respective issue dates or at
the Closing Date referred to below, include an untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. Notwithstanding the foregoing, this representation and warranty does
not apply to statements or omissions from the Registration Statement or the
Prospectus or any amendments or supplements thereto made in reliance upon and in
conformity with information furnished or confirmed in writing to the Company by
or on behalf of the Selling Stockholder or any Underwriter expressly for use in
the Registration Statement or the Prospectus or any amendments or supplements
thereto.
 
     (ii) No stop order suspending the effectiveness of the Registration
Statement or preventing or suspending the use of the Prospectus has been issued
and no proceedings for that purpose are pending or threatened or, to the best
knowledge of the Company, contemplated by the Commission; no stop order
suspending the sale of the Shares in any jurisdiction has been issued and no
proceedings for that purpose are pending or, to the best knowledge of the
Company, threatened or are contemplated; and any request of the commission for
additional information (to be included in the Registration Statement or the
Prospectus or otherwise) has been complied with.
 
     (iii) The Incorporated Documents when they became effective or were filed
with the Commission, as the case may be, complied in all material respects with
the requirements of the 1933 Act, the 1933 Act Regulations, the 1934 Act or the
1934 Act Regulations, as applicable, and any documents so filed and incorporated
by reference subsequent to the date of the Prospectus shall, when they are filed
with the Commission, conform in all material respects to the requirements of the
1933 Act, 1933 Act Regulations, 1934 Act and the 1934 Act Regulations, as
applicable.
 
     (iv) Price Waterhouse, who are reporting upon the audited consolidated
financial statements and schedules included in the Registration Statement, are
independent public accountants as required by the 1933 Act and the 1933 Act
Regulations. The Company and the Subsidiaries (as hereinafter defined) maintain
a system of internal accounting controls sufficient to provide reasonable
assurance that (i) transactions are executed in accordance with management's
general and specific authorizations; (ii) transactions are recorded as necessary
to permit preparations of financial statements in conformance with generally
accepted accounting principles and to maintain accountability for assets; (iii)
access to assets is permitted only in accordance with management's general or
specific authorizations; and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.
 
                                        2
   4
 
     (v) The Company has all requisite corporate power and authority to execute,
deliver and perform its obligations under this Agreement, and this Agreement has
been duly authorized, executed and delivered by the Company and constitutes the
valid and binding agreement of the Company, and is enforceable against the
Company in accordance with its terms.
 
     (vi) The consolidated financial statements included in the Registration
Statement present fairly the financial position of the Company and the
Subsidiaries (as hereinafter defined) as of the dates indicated and the
consolidated statements of operations, stockholders' equity and cash flows of
the Company and the Subsidiaries for the periods specified. Such financial
statements have been prepared in conformity with generally accepted accounting
principles applied on a consistent basis throughout the periods involved. The
financial statement schedules, if any, included in the Registration Statement
present fairly the information required to be stated therein.
 
     (vii) The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Nevada with corporate power
under such laws to own, lease and operate its properties and conduct its
business as described in the Prospectus; and the Company is duly qualified to
transact business as a foreign corporation and is in good standing in each other
jurisdiction in which it owns or leases property of a nature, or transact
business of a type, that would make such qualification necessary, except to the
extent that the failure to so qualify or be in good standing would not have a
material adverse effect on the business, financial condition or results of
operations of the Company and the Subsidiaries (as hereinafter defined), taken
as a whole ("Material Adverse Effect").
 
     (viii) The Company's only subsidiaries are listed on Exhibit A hereto
(collectively, the "Subsidiaries"). U-Haul International, Inc., Ponderosa
Holdings, Inc. (whose Significant Subsidiaries are Oxford Life Insurance Company
and Republic Western Insurance Company) and Amerco Real Estate Company are the
only subsidiaries that are "significant subsidiaries" of the Company as defined
in Section 1-02 of Regulation S-X under the Securities Act (collectively, the
"Significant Subsidiaries"). Each Significant Subsidiary is a corporation duly
incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation with corporate power under such laws to own,
lease and operate its properties and conduct its business as described in the
Prospectus; and each Subsidiary is duly qualified to transact business as a
foreign corporation and is in good standing in each other jurisdiction in which
it owns or leases property of a nature, or transacts business of a type, that
would make such qualification necessary, except to the extent that the failure
to so qualify or be in good standing would not have a Material Adverse Effect.
All of the outstanding shares of capital stock of each Subsidiary have been duly
authorized and validly issued and are fully paid and non-assessable (except for
the shares of the capital stock of Oxford Life Insurance Company and Republic
Western Insurance Company that are further assessable to the extent of their
respective par values in accordance with Article 14, Section 11 of the
Constitution of the State of Arizona), and are owned by the Company, directly or
through one or more Subsidiaries, free and clear of any pledge, lien, security
interest, claim or encumbrance of any kind; none of the outstanding shares of
capital stock of the Subsidiaries was issued in violation of the preemptive or
similar rights of any stockholder of such corporation arising by operation of
law, under the charter or bylaws of any Subsidiary or under any agreement to
which the Company or any Subsidiary is a party.
 
     (ix) The Company had at the date indicated a duly authorized and
outstanding capitalization as set forth in the Prospectus and the Shares conform
in all material respects to the description thereof contained in the Prospectus.
 
     (x) The Shares to be sold by the Selling Stockholder pursuant to this
Agreement have been duly authorized and are validly issued, fully paid and
non-assessable; no holder thereof shall be subject to personal liability by
reason of being such holder; such Shares are not subject to the preemptive or
other similar rights of any stockholder of the Company arising by operation of
law, under the charter and bylaws of the Company or under any agreement to which
the Company is a party, except as have been waived.
 
     (xi) Except as disclosed in the Prospectus, there are no outstanding
options, warrants or other rights calling for issuance of, and no commitments,
plans or arrangements to issue, any shares of capital stock of the Company or
any security convertible into, exercisable for, or exchangeable for capital
stock of the Company.
 
                                        3
   5
 
There is outstanding no security or other instrument which by its terms is
convertible into or exchangeable for capital stock of the Company, except as
described in the Prospectus. Except as disclosed in the Prospectus, there is no
commitment, plan or arrangement to change or alter the rights, preferences or
privileges of any outstanding class or series of the capital stock of the
Company.
 
     (xii) All of the outstanding shares of capital stock of the Company,
including the Shares, have been duly authorized and validly issued and are fully
paid and non-assessable; and none of the outstanding shares of Common Stock of
the Company was issued in violation of the preemptive or other similar rights of
any stockholder of the Company arising by operation of law, under the charter
and bylaws of the Company or under any agreement to which the Company or any
Subsidiary is a party.
 
     (xiii) Since the respective dates as of which information is given in the
Registration Statement and the Prospectus, except as otherwise stated therein or
contemplated thereby, there has not been (A) any material adverse change in the
business, financial condition or results of operations of the Company and the
Subsidiaries, taken as a whole ("Material Adverse Change"), whether or not
arising in the ordinary course of business, (B) any transaction entered into by
the Company or any of the Subsidiaries, other than in the ordinary course of
business that is material to the Company and the Subsidiaries, taken as a whole,
(C) any changes in the capital stock or long-term debt of the Company or any
Subsidiaries, or (D) any dividend or distribution of any kind declared, paid or
made by the Company, on its capital stock, except for dividends declared and
paid on the Series A 8 1/2% Preferred Stock.
 
     (xiv) Neither the Company nor any Significant Subsidiary is in violation of
its charter or in default in the performance or observance of any obligation,
agreement, covenant or condition contained in any contract, indenture, mortgage,
loan agreement, note, lease or other agreement or instrument to which it is a
party or by which it is bound or to which any of its properties or assets is
subject, except for such defaults that would not have a Material Adverse Effect.
The execution and delivery of this Agreement by the Company, the consummation by
the Company of the transactions contemplated in this Agreement and compliance by
the Company with the terms of this Agreement have been duly authorized by all
necessary corporate action on the part of the Company and do not and will not
result in any violation of the charter or bylaws of the Company or any
Subsidiary, and do not and will not conflict with, or result in a breach of any
of the terms or provisions of, or constitute a default under, or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Company or the Subsidiaries under (A) any indenture, mortgage,
loan agreement, note, lease or other agreement or instrument to which the
Company or any of the Subsidiaries is a party or by which the Company or any of
the Subsidiaries is bound or to which any of the Company's or any of the
Subsidiaries' properties or assets is subject (except for such conflicts,
violations, defaults or breaches as have been waived), or (B) any existing
applicable law, rule, regulation, judgment, order or decree of any government,
governmental instrumentality or court having jurisdiction over the Company or
any of the Subsidiaries or any of the Company's or any of the Subsidiaries'
properties or assets, in each case, except as disclosed in the Prospectus and
except for such conflicts, breaches, violations or defaults or liens, charges or
encumbrances that would not have a Material Adverse Effect.
 
     (xv) The Company is not required to obtain any authorization, approval,
consent or license of any government, governmental instrumentality or court
(other than under the 1933 Act and the 1933 Act Regulations and the Securities
or blue sky laws of the various states) in connection with the due
authorization, execution, delivery and performance by the Company of this
Agreement and the valid sale and delivery of the Shares.
 
     (xvi) Except as disclosed in the Prospectus, there is no action, suit, or
proceeding before or by any government, governmental instrumentality or court,
domestic or foreign, now pending or, to the knowledge of the Company, threatened
against or affecting the Company or any Subsidiary that is required to be
disclosed in the Prospectus or that could reasonably be expected to result in
any Material Adverse Change, or that could reasonably be expected to materially
and adversely affect the properties or assets of the Company and the
Subsidiaries, taken as a whole, or that could reasonably be expected to
materially and adversely affect the consummation of the transactions
contemplated in this Agreement.
 
                                        4
   6
 
     (xvii) There are no contracts or documents of a character required to be
described in the Registration Statement or the Prospectus or to be filed as
exhibits to the Registration Statement that are not described and filed as
required.
 
     (xviii) Each of the Company and the Subsidiaries owns, or has valid rights
to use in the manner currently used or proposed to be used, all properties and
assets described in the Prospectus, except such as do not materially impair or
interfere with the current use made of such properties or could not reasonably
be expected to have a Material Adverse Effect.
 
     (xix) Each of the Company and the Subsidiaries owns or possesses all
foreign and domestic governmental licenses, permits, certificates, consents,
orders, approvals and other authorizations (collectively, "Government Licenses")
necessary to own or lease, as the case may be, and to operate its properties and
to carry on its business as presently conducted, except where the failure to own
or possess such Governmental Licenses could reasonably be expected to not have a
Material Adverse Effect, and neither the Company nor any Subsidiary has received
any notice of proceedings relating to revocation or modification of any such
Governmental Licenses that, singly or in the aggregate, if the subject of an
unfavorable decision, rulings or findings, could reasonably be expected to have
a Material Adverse Effect.
 
     (xx) Each of the Company and the Subsidiaries owns or possesses, or has the
right to use or can acquire on reasonable terms, trademarks, service marks and
trade names (collectively, "intellectual property") necessary to carry on their
business as presently operated by them, except where the failure to own or
possess or have the right to use or ability to acquire any such intellectual
property would not have a Material Adverse Effect, and neither the Company nor
any of the Subsidiaries has received any notice of infringement of or conflict
with asserted rights of others with respect to any intellectual property or of
any facts which would render any intellectual property invalid or inadequate to
protect the interest of the Company or any of the Subsidiaries therein and which
infringement or conflict, singly or in the aggregate, if the subject of any
unfavorable decision, ruling or findings or invalidity or inadequacy, would have
a Material Adverse Effect.
 
     (xxi) Except as disclosed in the Prospectus, the Company and the
Subsidiaries comply in all material respects with all Environmental Laws (as
defined below), except to the extent that failure to comply with such
Environmental Laws would not have a Material Adverse Effect. To the knowledge of
the Company, other than as disclosed in the Prospectus, none of the Company nor
the Subsidiaries (i) is the subject of any pending or threatened federal, state
or local investigation evaluating whether any remedial action by the Company or
any Subsidiary is needed to respond to a release of any Hazardous Materials (as
defined below) into the environment, resulting from the Company's or any of the
Subsidiaries' business operations or ownership or possession of any of their
properties or assets or (ii) is in contravention of any Environmental Law that,
in the case of (i) or (ii), could reasonably be expected to have a Material
Adverse Effect. Except as disclosed in the Prospectus, neither the Company nor
any Subsidiary has received any notice or claim, nor are there pending or, to
the knowledge of the Company, threatened lawsuits against them, with respect to
violations of an Environmental Law or in connection with any release of
Hazardous Material into the environment that, in the aggregate, if the subject
of any unfavorable decision, ruling or finding, could reasonably be expected to
have a Material Adverse Effect. As used herein, "Environmental Laws" means any
federal, state or local law or regulation applicable to the Company's or any of
the Subsidiaries' business operations or ownership or possession of any of their
properties or assets relating to environmental matters, and "Hazardous
Materials" means those substances that are regulated by or form the basis of
liability under any Environmental Laws.
 
     (xxii) No labor dispute exists with the Company's or the Subsidiaries'
employees or, to the knowledge of the Company, is imminent that could reasonably
be expected to have a Material Adverse Effect; and neither the Company nor the
Subsidiaries are aware of any existing or imminent labor disturbance by the
employees of its principal suppliers, manufacturers or contractors which might
be expected to result in any Material Adverse Change. No collective bargaining
agreement exists with any of the Company's or any of the Subsidiaries' employees
and, to the best knowledge of the Company, no such agreement is imminent.

indirectly, any action designed to cause or result in or which has constituted
or which might reasonably be expected to cause or result in, under the 1934 Act,
the 1934 Act Regulations or otherwise, the stabilization or manipulation of the
price of any
 
                                        5
   7
 
security of the Company to facilitate the sale or resale of the Shares. No bid
or purchase by the Company and, to the best knowledge of the Company, no bid or
purchase that could be attributed to the Company (as a result of bids or
purchases by an "affiliated purchaser" within the meaning of Rule 10b-6 under
the 1934 Act) for or of the Common Stock, any securities of the same class or
series as the Common Stock or any securities immediately convertible into or
exchangeable for or that represent any right to acquire the Common Stock, is now
pending or in progress or will have commenced at any time prior to the
completion of the distribution of the Shares.
 
     (xxiv) Except as disclosed in the Prospectus, all United States federal
income tax returns of the Company and the Subsidiaries required by law to be
filed have been filed and all taxes shown by such returns or otherwise assessed,
which are due and payable, have been paid, except tax assessments, if any, as
are being contested in good faith and as to which adequate reserves have been
provided. To the best of the Company's knowledge, the charges, accruals and
reserves on the respective books of the Company and the Subsidiaries in respect
of any United States federal income tax liability for any years not finally
determined are adequate to meet any assessments or re-assessments for additional

would not have a Material Adverse Effect.
 
     (xxv) Except as disclosed in the Prospectus, there are no outstanding
loans, advances or guaranties of indebtedness by the Company to or for the
benefit of any of its "affiliates," as such term is defined in the 1933 Act
Regulations, or any of the officers or directors of any of the Subsidiaries, or
any of the members of the families of any of them.
 
     (xxvi) There are no holders of securities (debt or equity) of the Company,
or holders of rights (including, without limitation, preemptive rights),
warrants or options to obtain securities of the Company or the Subsidiaries, who
have the right to request the Company to register securities held by them under
the 1933 Act, other than as disclosed in the Prospectus.
 
     (xxvii) Each of the Company and the Subsidiaries is conducting its business

and regulations of the jurisdictions in which it is conducting business except
to the extent that such failure to comply would not have a Material Adverse
Effect.
 
     (xxviii) The Company is not an investment company within the meaning of the
Investment Company Act of 1940, as amended.
 
     (xxix) The Shares are free from any Company-imposed restrictions preventing

other person associated with or acting on behalf of the Company has, directly or
indirectly: used any corporate funds for unlawful contributions, gifts,
entertainment or other unlawful expenses relating to political activity; made

or made any bribe, rebate, payoff, influence payment, kickback or other unlawful
payment.
 
     (xxxi) Except as set forth in the Prospectus, no officer, director or

are defined in Rule 405 of the 1933 Act Regulations) of any of the foregoing

Shares.
 
     (xxxiv) The Company has not distributed and will not distribute prior to
the Closing Date any prospectus or other offering material in connection with
the offering and sale of the Shares other than the Prospectus, the Registration
Statement and any other material that may be permitted by the 1933 Act and the
1933 Act Regulations.
 
     (b) The Selling Stockholder represents and warrants to, and agrees with
each of the Underwriters as follows:
 
     (i) The Selling Stockholder is not prompted to sell the Shares to be sold
by the Selling Stockholder by any information concerning the Company that is not
set forth in the Prospectus or other documents filed by the Company with the
Commission pursuant to the periodic reporting and other informational
requirements of the 1934 Act.
 
     (ii) When the Registration Statement and any further amendments thereto
shall become effective, neither the Registration Statement nor any such
amendment will contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent that such statements or omissions were made
in reliance upon and in conformity with information furnished or confirmed in
writing to the Company by the Selling Stockholder expressly for use in the
Registration Statement or the Prospectus or any amendments or supplements
thereto. Without having undertaken to determine independently the accuracy or
completeness of either the representations and warranties of the Company
contained in Section l(a) hereof or the information contained in the
Registration Statement, including the Prospectus (and any amendment or
supplement thereto), the Selling Stockholder (A) does not have any actual
knowledge that the representations and warranties of the Company contained in
Section l(a) hereof are not true and correct, and (B) is familiar with the
Registration Statement and does not have any actual knowledge that the
Registration Statement contains any untrue statements of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading; except that the foregoing shall not
apply to statements in or omissions from any such document (A) made in reliance
upon, and in conformity with, written information furnished to the Company by
the Underwriters specifically for use in the preparation thereof or (B) to the
extent, if any, such statements or omissions are inconsistent with information
furnished in writing to the Company or the Underwriters by the Selling
Stockholder expressly for this purpose.
 
     (iii) The Selling Stockholder has full right, power and authority to enter
into this Agreement, the Power of Attorney (as defined below) and the Custody
Agreement (as defined below) and to sell, transfer and deliver the Shares

behalf of such Selling Stockholder and to take certain other actions with
respect hereto and thereto; each of the Power of Attorney and the Custody

enforceable in accordance with its terms, and each of such Attorneys, acting
alone, is authorized to execute and deliver this Agreement, the Custody
Agreement and the certificate contemplated by Section   of this Agreement on
behalf of such Selling Stockholder, to determine the purchase price to be paid

completion of the distribution of the Shares by the Selling Stockholder.
 
     (xi) Neither the Selling Stockholder nor any of his affiliates directly or

     (xiii) The Selling Stockholder will review the Prospectus and comply with
all agreements and satisfy all conditions on his part to be complied with or
satisfied pursuant to this Agreement on or prior to the Closing Date and will
advise one of his Attorneys, prior to the Closing Date if any statement to be

     (xiv) The Selling Stockholder has not relied upon any representation by the
Underwriters with respect to any tax consequences (federal, state or local) of
the transactions contemplated hereby, or otherwise. The Selling Stockholder
acknowledges that any tax liability that might arise with respect to the Shares
to be sold by the Selling Stockholder shall be solely the responsibility of the
Selling Stockholder.
 
     (c) Any certificate signed by any officer of the Company and delivered to
you or to Grover Wickersham, P.C., as counsel for the Underwriters pursuant to

Stockholder the number of Shares set forth in Schedule A opposite the name of
such Underwriter (plus such additional number of Shares that such Underwriter
may become obligated to purchase pursuant to Section 10 hereof).
 
     The purchase price per Share to be paid by the Underwriters shall be
$          . The initial public offering price of the Shares shall be

The Selling Stockholder agrees that the Shares represented by the certificates

under this Agreement, that the arrangements made by such Selling Stockholder for
such custody, including the Power of Attorney, are to that extent irrevocable
and that the obligations of such Selling Stockholder under this Agreement shall
not be terminated by the act of such Selling Stockholder or by operation of law,
whether by the death or incapacity of such Selling Stockholder or the occurrence
of any other event, except as specifically provided in this Agreement or in the
Custody Agreement. If the Selling Stockholder should die or become
incapacitated, or if any other such event should occur before the delivery of
the Shares hereunder, certificates for the Shares to be sold by such Selling
Stockholder shall, except as specifically provided in this Agreement or in the
Custody Agreement, be delivered by the Custodian in accordance with the terms
and conditions of this Agreement as if such death, incapacity or other event has
not occurred, regardless of whether the Custodian shall have received notice of
such death or other event.

purchase price (less the nonaccountable expense allowance provided for in
Section 4 of this Agreement) for, and delivery of certificates for the Shares

on the fifth full business day after the date of this Agreement, or (ii) at such
other time not more than seven full business days after such fifth business day
as you, the Company and the Selling Stockholder shall determine (the "Closing
Date"). As used in this Agreement, "business day" means a day on which the New
York Stock Exchange is open for trading and on which banks in New York are open
for business and not permitted by law or executive order to be closed. Payment
shall be made to the Selling Stockholder by wire transfer pursuant to
instructions of the Selling Stockholder, certified or official bank check or
checks in California Clearing House funds or similar next day funds payable to
the
 
                                        9
   11
 
order of the Selling Stockholder against delivery to you for the respective
accounts of the several Underwriters of certificates for the Shares to be
purchased by them.
 
     (d) Certificates for the Shares to be purchased by the Underwriters shall
be in such denominations and registered in such names as you may request in
writing at least two full business days before the applicable Closing Date. The
certificates for the Shares will be made available for examination and packaging
by you at the offices of Alex. Brown & Sons, New York, New York, not later than
one full business day prior to the Closing Date.
 
     (e) It is understood that each Underwriter has authorized you, for its
account, to accept delivery of, receipt for, and make payment of the purchase

(but shall not be obligated to) make payment of the purchase price for the
Shares to be purchased by any Underwriter whose check or checks shall not have
been received by the applicable Closing Date.
 
     (f) It is understood that the several Underwriters propose to offer the
Shares for sale to the public as soon as you, in your capacity as the
Representative, deem it advisable to do so. The Shares are to be initially
offered to the public at the public offering price set forth in the Prospectus.
The Representative may from time to time thereafter change the public offering
price and other selling terms.
 
     (g) The information set forth in the last paragraph on the front cover page
(insofar as such information relates to the Underwriters), the legend respecting
stabilization set forth on the inside front cover page, the statements set forth
under the caption, "Underwriting" in any Preliminary Prospectus and in the
Prospectus constitute the only information furnished by the Underwriters to the
Company for inclusion in any Preliminary Prospectus, the Prospectus or the
Registration Statement.
 
SECTION 3.  CERTAIN COVENANTS OF THE COMPANY.
 
     The Company covenants with each Underwriter as follows:
 
     (a) The Company will use its best efforts to cause the Registration
Statement to become effective and, if the Company elects to rely upon Rule 430A
and subject to Section 3(b), will comply in all material respects with the
requirements of Rule 430A and will notify you promptly, (i) when the
Registration Statement, or any post-effective amendment to the Registration
Statement, shall have become effective, or any supplement to the Prospectus or
any amended Prospectus shall have been filed, (ii) of the receipt of any
comments from the Commission, (iii) of any request by the Commission to amend
the Registration Statement or amend or supplement any Prospectus or for
additional information and (iv) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or of any order
preventing or suspending the use of any preliminary prospectus, or of the
suspension of the qualification of the Shares for offering or sale in any
jurisdiction, or of the institution or threatening of any proceedings for any of
such purposes. The Company will make every reasonable effort to prevent the
issuance of any such stop order or of any order preventing or suspending such
use and, if any such order is issued, to obtain the lifting thereof at the
earliest possible moment.
 
     (b) The Company will not at any time file or make any amendment to the
Registration Statement, or any amendment or supplement (i) if the Company has
not elected to rely upon Rule 430A to the Prospectus or (ii) if the Company has
elected to rely upon Rule 430A, to either the prospectus included in the
Registration Statement at the time it becomes effective or to the Prospectus, of
which you shall not have previously been advised and furnished a copy or to
which you or Grover Wickersham, P.C., as counsel for the Underwriters shall have
promptly and reasonably objected in writing; provided that such objections shall
not prevent the filing of any amendment or supplement which, in the opinion of
counsel for the Company, is required by the 1933 Act or the 1933 Act
Regulations, in which case the Company shall make such changes in any such
document prior to the filing thereof as the Underwriters upon advice of counsel
may reasonably request.
 
     (c) The Company has furnished or will furnish to you and your counsel,
without charge, two signed copies of the Registration Statement as originally
filed and of all amendments thereto, whether filed before or
 
                                       10
   12
 
after the Registration Statement becomes effective, copies of all exhibits and
documents filed therewith and signed copies of all consents and certificates of
experts and has furnished or will furnish to you, for each other Underwriter,
one conformed copy of the Registration Statement as originally filed and each
amendment thereto (without exhibits). In addition, the Company has furnished or
will furnish to you and your counsel, without charge, such additional conformed
copies of the Registration Statement, any amendments or supplements thereto and
exhibits as shall be reasonably requested.
 
     (d) The Company will deliver to each Underwriter, without charge, from time
to time until the effective date of the Registration Statement as many copies of
each preliminary prospectus as such Underwriter may reasonably request, and the
Company hereby consents to the use of such copies for purposes permitted by the
1933 Act. The Company will deliver to each Underwriter, without charge, as soon
as the Registration Statement shall have become effective and thereafter from
time to time as requested during the period when the Prospectus is required to
be delivered under the 1933 Act and prior to the expiration of ninety days after
the effective date of the Registration Statement such number of copies of the
Prospectus (as supplemented or amended) as such Underwriter may reasonably
request, and in case any Underwriter is required to deliver a prospectus in
connection with sales of any of the Shares at any time ninety days or more after
the effective date of the Registration Statement upon such Underwriter's request
through you, but at the expense of such Underwriter, the Company will prepare
and deliver to such Underwriter, as many copies as you may request of an amended
or supplemented Prospectus complying with Section 10(a)(3) of the 1933 Act.
 
     (e) The Company will comply to the best of its ability with the 1933 Act
and the 1933 Act Regulations, and the 1934 Act, and the 1934 Act Regulations so
as to permit the completion of the distribution through the Underwriters of the
Shares as contemplated in this Agreement and in the Prospectus. If at any time
when a prospectus is required by the 1933 Act to be delivered in connection with
Sales by the Underwriters of the Shares any event shall occur or condition exist
as a result of which it is necessary, in the opinion of counsel for the
Underwriters or counsel for the Company, to amend the Registration Statement or
amend or supplement any Prospectus in order that the Prospectus will not include
an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein not misleading in the light of
the circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of either such counsel, at any such time to
amend the Registration Statement or amend or supplement any Prospectus in order
to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the
Company will promptly prepare and file with the Commission, subject to Section
3(b), such amendment or supplement as may be necessary to correct such untrue
statement or omission or to make the Registration Statement or the Prospectus
comply with such requirements, provided that the Company shall make such changes
in any such document as the Underwriters upon advice of counsel may reasonably
request; provided, further, that the Company shall determine the final terms of
any such amendment or supplement.
 
     (f) The Company will endeavor, in cooperation with the Underwriters, to
qualify the Shares for offering and sale under the applicable securities laws of
such states and other jurisdictions as you may designate and to maintain such
qualifications in effect for a period of not less than one year from the
effective date of the Registration Statement; provided, however, that neither
the Company nor any Subsidiary shall be obligated to file any general consent to
service of process or to qualify as a foreign corporation or as a dealer in
securities in any jurisdiction in which it is not so qualified or to subject
itself to taxation in respect of doing business in any jurisdiction in which it
is not otherwise so subject. The Company will file such statements and reports
as may be required by the laws of each jurisdiction in which the Shares have
been qualified as above provided.
 
     (g) The Company will make generally available (within the meaning of
Section 11(a) of the 1933 Act and the 1933 Act Regulations) to its security
holders as soon as practicable, but not later than 15 months after the date of

1933 Act or the 1933 Act Regulations, but which shall satisfy the provisions of
Section 11(a) of the 1933 Act Regulations), covering a period of 12 months
beginning after the effective date of the Registration Statement but beginning
not later than the first day of the Company's fiscal quarter next following such

steps as it deems necessary to ascertain promptly whether the form of prospectus
transmitted for filing under Rule 424(b) was received for filing by the
Commission and, in the event that it was not, it will promptly file such
prospectus.
 
     (j) The Company will furnish to you as early as practicable prior to the
Closing Date, but not less than two full business days prior thereto, a copy of
its latest available unaudited interim financial statements that have been read

Agreement, the Company will promptly furnish to each of you, and to each
Underwriter who may so request in writing, copies of all periodic and special
reports furnished to stockholders of the Company, of all information, documents

Stock is in due and proper form and complies with all applicable requirements of
the General Corporation Law of Nevada.
 
     (vi) The description in the Registration Statement and the Prospectus of
the charter and bylaws of the Company and of statutes and contracts are accurate
in all material respects and fairly present the information required to be
presented by the 1933 Act and the 1933 Act Regulations with respect to such
statutes and contracts.
 
     (vii) The Company has the corporate power to enter into and perform its
obligations under this Agreement and this Agreement has been duly authorized,
executed and delivered by the Company and, assuming due authorization, execution
and delivery by the other parties hereto, is a valid and binding agreement of
the Company. Such counsel need not express an opinion with respect to the
limitations and exceptions to the enforceability of contracts and obligations in
general, including, without limitation: (a) the effect of bankruptcy,
insolvency, reorganization, arrangement, moratorium, fraudulent conveyance and
other similar laws relating to or affecting the rights of creditors generally;
(b) the effect of general principles of equity and similar principles,
including, without limitation, concepts of materiality, reasonableness,
unconscionability, good faith and fair dealing and the possible unavailability
of specific performance, injunctive relief or other equitable remedies,
regardless of whether considered in a proceeding in equity or at law, and the
effect of public policy; and (c) the enforceability of provisions relating to
indemnity or contribution for liabilities arising under the 1933 Act.
 
     (viii) The Company is not required to obtain any authorization, approval,
consent or license of any government, governmental instrumentality or court
(other than under the 1933 Act and the 1933 Act
 
                                       14
   16
 
Regulations, and state securities laws) under federal or Nevada or Arizona law
for the sale and delivery of the Shares by the Selling Stockholder to the
Underwriters.
 
     (ix) The execution and delivery of this Agreement by the Company, the
consummation by the Company of the transactions contemplated in this Agreement
and the compliance by the Company with the terms of this Agreement have been
duly authorized by all necessary corporate action on the part of the Company and
do not and will not result in any violation of the Restated Articles of
Incorporation, as amended (the "Articles of Incorporation"), or the Restated
By-Laws, as currently in effect (the "By-Laws"), of the Company or any of the
Significant Subsidiaries incorporated in Arizona or Nevada, and do not and will
not conflict with, or constitute a breach or violation of, any of the terms and
provisions of, or constitute a default under, or result in the creation or
imposition of any lien or encumbrance upon any property or assets of the Company
or any of the Significant Subsidiaries where such default would have a Material
Adverse Effect under (A) any indenture, mortgage, deed of trust, loan or credit
agreement, bond, debenture, note agreement or any other agreement or instrument
known to us to which the Company or any of its Subsidiaries incorporated in
Arizona or Nevada is a party or by which it is bound, (B) any existing
applicable federal or Nevada or Arizona corporate laws, rules or regulations,
and except to the extent that the indemnification provisions thereof may
conflict with any applicable law, rule or regulation or (C) to such counsel's
knowledge, any judgment, order, writ or decree of any government agency or body,
domestic or foreign, having jurisdiction over the Company, any of its
Subsidiaries incorporated in Arizona or Nevada or any of their properties or
operations. Such counsel need express no opinion, however, as to whether the
execution and delivery of, or the performance by the Company of its obligations
under this Agreement will constitute a violation of, or default under, any
financial covenant or financial ratios contained in any of the agreements
referred to in the preceding sentence.
 
     (x) Such counsel has been advised by the Division of Corporation Finance of
the Commission that the Registration Statement has become effective under the
1933 Act, and, to the best of the knowledge of such counsel, no stop order
suspending the effectiveness of the Registration Statement has been issued and
no proceedings for that purpose have been instituted or are pending or are
contemplated under the 1933 Act; any required filing of the Prospectus or any
supplement thereto pursuant to Rule 424(b) of the 1933 Act Regulations have been
made in the manner and within the time period required by Rule 424(b).
 
     (xi) The Registration Statement (including the Rule 430a information, if
applicable), the Prospectus and each amendment or supplement to the Registration
Statement and Prospectus, as of their respective effective or issue dates (other
than the financial statements, notes or schedules thereto and other financial or
statistical data and supplemental schedules included therein or omitted
therefrom, as to which such counsel need express no opinion), complied as to
form in all material respects with the requirements of the 1933 Act and the 1933
Act Regulations.
 
     (xii) The Company is not an investment company within the meaning of the
Investment Company Act of 1940, as amended.
 
     (xiii) All descriptions in the Prospectus of contracts and other documents
filed as exhibits to the Registration Statement or incorporated by reference to
which the Company and the Subsidiaries are parties are accurate in all material
respects.
 
     (xiv) To such counsel's knowledge, no holders of the Company's securities
have rights to the registration of shares of Common Stock or other securities in
connection with the Offering as a result of the filing of the Registration
Statement by the Company or the offering contemplated hereby, except for any
such rights which have been waived.
 
     In addition, such opinion shall state that such counsel has participated in
the preparation of the Registration Statement and Prospectus and in conferences
with officers and other representatives of the Company, representatives of the
independent public accountants for the Company, and your representatives and
your counsel at which the contents of the Registration Statement, the Prospectus
and related matters were discussed and, although such counsel need not pass upon
or assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement or the Prospectus and
although such counsel has not undertaken to verify independently the accuracy or
completeness of the
 
                                       15
   17
 
statements in the Registration Statement and the Prospectus and, therefore,
would not necessarily have become aware of any material misstatement of fact or
omission to state a material fact, on the basis of and subject to the foregoing
and in reliance as to materiality upon the opinions of officers and other
representatives of the Company, no facts have come to such counsel's attention
which have caused such counsel to believe that either the Registration Statement
or the Prospectus (other than the financial statements, notes or schedules
thereto and other financial or statistical data and supplemental schedules
included therein or omitted therefrom, as to which such counsel need express no
opinion) contained as of its date or contains as of the date of such opinion any
untrue statement of a material fact or omitted as of its date or omits as of the
date of such opinion to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.
 
     In giving such opinion, such counsel may rely as to all matters governed by
laws of jurisdiction other than the State of Arizona, the General Corporation
Law of the State of Nevada or the federal law of the United States, on opinions
of other local counsel in such jurisdictions, who shall be counsel satisfactory
to Grover Wickersham, P.C., as counsel for the Underwriters, in which case the
opinion shall state that they believe you and they are entitled to so rely. Such
counsel may also state that, insofar as such opinions involve factual matters,
they have relied, to the extent they deem proper, upon certificates of officers
of the Company and the Subsidiaries and certificates of public officials.
 
     (c) At the Closing Date, you shall have received a signed opinion of Gary
V. Klinefelter, General Counsel for the Company, dated as of such Closing Date,
together with reproduced copies of such opinion for each of the other
Underwriters, in form and substance reasonably satisfactory to the Underwriters
upon advice of counsel, to the effect that:
 
     (i) Such counsel does not know of any pending or threatened legal or
governmental actions, suits or proceedings, required to be described in the
Prospectus that are not described as required; to the best knowledge of such
counsel, there are no agreements, contracts, licenses, leases or documents of a
character required by the 1933 Act or the 1933 Act Regulations to be described
or referred to in the Registration Statement or Prospectus or to be filed as
exhibits to the Registration Statement that are not described or referred to in
the Prospectus or the Registration Statement or filed as exhibits to the
Registration Statement.
 
     (ii) To the knowledge of such counsel, no default exists in the performance
or observance of any obligation, agreement, covenant or condition contained in
any contract, indenture, loan agreement, note, lease or other agreement or
instrument to which the Company or any of the Subsidiaries is party or to which
any of their respective properties are bound, except as disclosed in the
Registration Statement and except for such defaults that would not have a
material adverse effect on the Company and the Subsidiaries, taken as a whole.
 
     (iii) The descriptions in the Prospectus of the statutes, regulations,
legal or governmental proceedings, contracts and other documents therein
described, to the extent that they constitute matters of law or legal
conclusion, have been reviewed by such counsel and fairly present the
information disclosed therein in all material respects.
 
     (iv) To the best knowledge of such counsel, except as set forth in the
Registration Statement and Prospectus, and except for the Shares to be sold by
the Selling Stockholder thereunder, (a) no holder of common Stock or other
securities of the Company has registration rights with respect to securities of
the Company and (b) all holders of securities of the Company having rights to
registration of such securities, as a result of the filing of the Registration
Statement by the Company have, with respect to the offering provided for in this
Agreement, waived such rights or such rights have expired by reason of lapse of
time following notification of the Company's intention to file the Registration
Statement.
 
     (v) The execution and delivery of this Agreement by the Company, the
consummation by the Company of the transactions contemplated in this Agreement
and compliance by the Company with the terms of this Agreement have been duly
authorized by all necessary corporate action on the part of the Company and do
not and will not result in any violation of the Articles of Incorporation or
By-Laws of the Company or any of the Subsidiaries, and do not and will not
conflict with, or constitute a breach of any of the terms or provisions of, or
constitute a default under, or result in the creation or imposition of any lien
or encumbrance under any
 
                                       16
   18
 
property or assets of the Company or any of the Subsidiaries where such default
would have a Material Adverse Effect under (A) any indenture, mortgage, deed of
trust, loan or credit agreement, bond, debenture, note agreement or any other
agreement or instrument to which the Company or any of the Subsidiaries is a
party or by which any of their respective properties are bound, (B) any existing
applicable Arizona or Nevada laws, rules or regulations (other than securities
or blue sky laws of the various states, as to which such counsel-need express no
opinion, and except to the extent that the indemnification provisions thereof
may conflict with any applicable Arizona or Nevada law, rule or regulation), or
(C) to such counsel's knowledge, any judgment, order, writ or decree of any
governmental agency or body, domestic or foreign, having jurisdiction over the
Company or any of the Subsidiaries or any of their respective properties or
operations.
 
     (vi) Each of the Company and its Subsidiaries is duly qualified to do
business as a foreign corporation in good standing in all jurisdictions, if any,
where it owns or leases real properties and in which the failure so to qualify
when taken in the aggregate would have a Material Adverse Effect.
 
     (vii) No authorization, approval, consent or license of any government,
governmental instrumentality or court (other than under the 1933 Act and the
1933 Act Regulations and the rules and regulations of the Commission thereunder,
and state securities law) is required to be made or obtained by the Company
under Arizona or Nevada law for the consummation by the Company of the
transactions contemplated in this Agreement.
 
     (viii) The Company has taken all necessary and appropriate action to remove
the Company's fight of first refusal set forth in Article VII, Section 2 of the
By-Laws with respect to the Shares.
 
     In addition, such opinion shall state that such counsel has participated in
the preparation of the Registration Statement and Prospectus and in conferences
with officers and other representatives of the Company, representatives of the
independent public accountants for the Company, and your representatives and
your counsel at which the contents of the Registration Statement, the Prospectus
and related matters were discussed and, although such counsel need not pass upon
or assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement or the Prospectus and
although such counsel has not undertaken to verify independently the accuracy or
completeness of the statements in the Registration Statement and the Prospectus
and, therefore, would not necessarily have become aware of any material
misstatement of fact or omission to state a material fact, on the basis of and
subject to the foregoing, no facts have come to such counsel's attention which
have caused such counsel to believe that either the Registration Statement or
the Prospectus (other than the financial statements, notes or schedules thereto
and other financial or statistical data and supplemental schedules included
therein or omitted therefrom, as to which such counsel need express no opinion)
contained as of its date or contains as of the date of such opinion any untrue
statement of a material fact or omitted as off its date or omits as of the date
of such opinion to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.
 
     Such counsel may also state that, insofar as such opinion involves factual
matters, they have relied, to the extent they deem proper, upon certificates of
officers of the Company and the Subsidiaries and certificates of public
officials.
 
     (d) At the Closing Date, you shall have received a signed opinion of Ryan,
Swanson & Cleveland, counsel for the Selling Stockholder, dated as of such
Closing Date, together with reproduced copies of such opinion for each of the
other Underwriters, in form and substance reasonably satisfactory to the
Underwriters upon advice of counsel, to the effect that:
 
     (i) No authorization, approval, consent or license of any government,
governmental instrumentality or court (other than under the 1933 Act and the
1933 Act Regulations and the rules and regulations of the Commission thereunder,
and state securities law) is necessary for the valid sale and delivery of the
Shares or for the consummation by the Selling Stockholder of the transactions
contemplated in this Agreement.
 
     (ii) The execution and delivery of this Agreement by the Selling
Stockholder, the delivery of the Shares sold by the Selling Stockholder to the
Underwriters, the consummation by the Selling Stockholder of the transactions
contemplated in this Agreement and the compliance by the Selling Stockholder
with the terms of
 
                                       17
   19
 
this Agreement do not and will not conflict with, or constitute a breach or
violation of, any of the terms and provisions of, or constitute a default under,
or result in the creation or imposition of any lien or encumbrance upon any
property or assets of the Selling Stockholder under (A) any indenture, mortgage,
deed of trust, loan or credit agreement, bond, debenture, note agreement or any
other agreement or instrument known to such counsel to which the Selling
Stockholder is a party or by which any of his respective properties are bound,
(B) except to the extent that the indemnification provisions thereof may
conflict with any applicable law, rule or regulation, any existing applicable
laws, rules or regulations, other than the securities or blue sky laws of the
various states, as to which such counsel need express no opinion, or (C) to such
counsel's knowledge, any judgment, order, writ or decree of any government
agency or body, domestic or foreign, having jurisdiction over the Selling
Stockholder or any of his properties or operations. Such counsel need express no
opinion, however, as to whether the execution and delivery of, or the
performance by the Selling Stockholder of his obligations under this Agreement
will constitute a violation of, or default under, any financial covenants or
financial ratios contained in any of the agreements referred to in the preceding
sentence.
 
     (iii) The Custody Agreement has been duly authorized, executed and
delivered by the Selling Stockholder and constitutes the valid and binding
agreement of the Selling Stockholder enforceable against the Selling Stockholder
in accordance with its terms.
 
     (iv) This Agreement has been duly executed and delivered by the Selling
Stockholder and constitutes the valid and binding obligation of the Selling
Stockholder enforceable against the Selling Stockholder in accordance with its
terms. Such counsel need not express an opinion with respect to the limitations
and exceptions to the enforceability of contracts and obligations in general,
including, without limitation: (a) the effect of bankruptcy, insolvency,
reorganization, arrangement, moratorium, fraudulent conveyance and other similar
laws relating to or affecting the rights of creditors generally; (b) the effect
of general principles of equity and similar principles, including, without
limitation, concepts of materiality, reasonableness, unconscionability, good
faith and fair dealing and the possible unavailability of specific performance,
injunctive relief or other equitable remedies, regardless of whether considered
in a proceeding in equity or at law, and the effect of public policy; and (c)
the enforceability of provisions relating to indemnity or contribution for
liabilities arising under the 1933 Act.
 
     (v) The Selling Stockholder is the sole registered owner of the Shares to
be sold by the Selling Stockholder; upon completion and registration with the
transfer agent of the sale of the Shares pursuant to this Agreement, each of the
Underwriters will be the registered owner of the Shares purchased by it from the
Selling Stockholder and, assuming the Underwriters purchased the Shares in good
faith and without prior notice of any adverse claim, the Underwriters will have
acquired the Shares free of any adverse claim, any lien in favor of the Company;
the owner of the Shares, if other than the Selling Stockholder, is precluded
from asserting against the Underwriters the ineffectiveness of any unauthorized
endorsement; and the Selling Stockholder has the full right and power (A) to
enter into this Agreement and the Custody Agreement and (B) to sell, transfer
and deliver the Shares to be sold by the Selling Stockholder under this
Agreement.
 
     In addition, such opinion shall state that such counsel has participated in
the preparation of the Registration Statement and Prospectus and in conferences
with officers and other representatives of the Company, representatives of the
independent public accountants for the Company, and your representatives and
your counsel at which the contents of the Registration Statement, the Prospectus
and related matters were discussed and, although such counsel need not pass upon
or assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement or the Prospectus and
although such counsel has not undertaken to verify independently the accuracy or
completeness of the statements in the Registration Statement and the Prospectus
and, therefore, would not necessarily have become aware of any material
misstatement of fact or omission to state a material fact, on the basis of and
subject to the foregoing, no facts have come to such counsel's attention which
have caused such counsel to believe that either the Registration Statement or
the Prospectus (other than the financial statements, notes or schedules thereto
and other financial or statistical data and supplemental schedules included
therein or omitted therefrom, as to which such counsel need express no opinion)
contained as of its date or contains as of the date of such opinion any untrue
statement of a material fact or omitted as off its date or omits as of the
 
                                       18
   20
 
date of such opinion to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.
 
     Such opinion shall be to such further effect with respect to the legal
matters relating to this Agreement and the sale of the Shares pursuant to this
Agreement as counsel for the Underwriters may reasonably request. Such counsel
may also state that, insofar as such opinion involves factual matters, they have
relied, to the extent they deem proper, upon certificates of officers of the
Company and the Subsidiaries and certificates of public officials.
 
     (e) At the Closing Date, you shall have received the favorable opinion of
Grover Wickersham, P.C. as counsel for the Underwriters, dated as of such
Closing Date, together with reproduced copies of such opinion for each of the
other Underwriters, to the effect that the opinions delivered pursuant to
Sections 5(b), (c) and (d) appear on their faces to be appropriately responsive
to the requirements of this Agreement except, specifying the same, to the extent
waived by you, and with respect to the legal existence of the Company, the
Shares, this Agreement, the Registration Statement, the Prospectus or such other
related matters as you may require. In giving such opinion, such counsel may
rely, as to all matters governed by the laws of jurisdictions other than the law
of the State of California and the federal law of the United States, upon the
opinions of counsel satisfactory to you. Such counsel may also state that,
insofar as such opinion involves factual matters, they have relied, to the
extent they deem proper, upon certificates of officers of the Company and
certificates of public officials.
 
     (f) At the Closing Date, (i) the Registration Statement and the Prospectus,
as they may then be amended or supplemented, shall conform in all material
respects to the requirements of the 1933 Act and the 1933 Act Regulations, the
Company shall have complied in all material respects with Rule 430A (if it shall
have elected to rely thereon), the Registration Statement, as it may then be
amended or supplemented, shall not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements in the Registration Statement not misleading, and the
Prospectus, as they may then be amended or supplemented, shall not contain an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements in the Prospectus, in
light of the circumstances under which they were made, not misleading, (ii)
there shall not have been, since the date as of which information is given in

ordinary course of business, (iii) no action, suit or proceeding at law or in
equity shall be pending or, to the knowledge of the Company, threatened against
the Company or the Subsidiaries that would be required to be set forth in the
Prospectus other than as set forth therein and no proceedings shall be pending

Subsidiaries or before or by any federal, state or other commission, board or
administrative agency that could reasonably be expected to have a Material
Adverse Effect, other than as set forth in the Prospectus, (iv) the Company
shall have complied in all material respects with all agreements and satisfied
in all material respects all conditions on its part to be performed or satisfied

shall have received a certificate of the Chairman or the President and the chief
financial or chief accounting officer of the Company, dated as of such Closing
Date, to such effect. As used in Section 5(f)(ii) and (iii), the term
"Prospectus" means the Prospectus in the form first used to confirm sales of the
Shares.
 
     (g) At the Closing Date, (i) the representations and warranties of the
Selling Stockholder set forth in Section 1(b) and in any certificates by or on

representations, warranties or statements of the Company and the Selling
Stockholder, the performance of any of the covenants of the Company and the
Selling Stockholder, or the fulfillment of any of the conditions herein
contained; and all proceedings taken by the Company and the Selling Stockholder
at or prior to such Closing Date in connection with the sale of the Shares as

4 herein. Notwithstanding any such termination, the provisions of Sections 7 and
8 herein shall remain in effect.
 
SECTION 6.  INDEMNIFICATION.
 
     (a) Subject to the conditions set forth below, the Company and the Selling
Stockholder agree to indemnify and hold harmless the Underwriters, any member of
the selling group, and each of such entities' officers, directors, partners,
employees, agents, and counsel, and each person, if any, who controls any one of
the Underwriters or selling group members within the meaning of Section 15 of
the 1933 Act or Section 20(a) of the Exchange Act, against any and all loss,
liability, claim, damage (or actions in respect thereof), and expense whatsoever
(which shall include, for all purposes of this Section 6, but not be limited to,
attorneys' fees and any and all expense whatsoever incurred in investigations
preparing or defending against any litigation, commenced or threatened, or any
claim whatsoever and any and all amounts paid in settlement of any claim or
litigation) as and when incurred arising out of, based upon, or in connection
with (i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any Preliminary Prospectus, the Registration Statement, or the
Prospectus (as from time-to-time amended and supplemented), or any amendment or
supplement thereto (including the 430A Information, if applicable), or (B) in
any application or other document or communication (in this Section 6,
collectively called an "application") in any jurisdiction in order to qualify
the Shares under the "blue sky" or securities laws thereof or filed with the
Commission or any securities exchange or national market system; or any omission
or alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (ii) any breach of
any representation, warranty, covenant or agreement of the Company or of the
Selling Stockholder contained in this Agreement. The foregoing agreement to
indemnify shall be in addition to any liability the Company and the Selling
Stockholder may otherwise have, including liabilities arising under this
Agreement. However, (i) the Company and the Selling Stockholder shall have no
liability under this Section 6 if such statement or omission was made in
reliance upon and in conformity with written information furnished to the
Company as stated in Section 6(b) with respect to the Underwriters by or on
behalf of the Underwriters expressly for inclusion in any Preliminary
Prospectus, the Registration Statement, or the Prospectus, or any amendment or
supplement thereto, or in any application, as the case may be, and (ii) the
Selling Stockholder shall be liable under this Section 6(a) only if such loss,
liability, claim, damage, or expense arises out of or is based upon the
representations and warranties of such Selling Stockholder
 
                                       20
   22
 
contained in Section l(b) hereof. The foregoing notwithstanding, the indemnity
provided for in this Section 6(a) with respect to any preliminary prospectus
shall not inure to the benefit of any Underwriter or selling group member (or
any person controlling such Underwriter or selling group member) from whom the
person asserting such loss, claim, damage or liability purchased the Shares that
are the subject thereof if such person did not receive a copy of the Prospectus
(or the Prospectus, as amended or supplemented) at or prior to confirmation of
the sale of the Shares to such person in any case where such delivery is
required by the 1933 Act and the true statement or omission or alleged untrue
statement or omission of a material fact contained in such preliminary
prospectus was corrected in the Prospectus (or the Prospectus as amended or
supplemented).
 
     If any action is brought against the Underwriters, any members of the
selling group or any of their respective officers, directors, partners,
employees, agents, or counsel, or any controlling persons of an Underwriter or
selling group member (an "indemnified party") in respect of which indemnity may
be sought against the Company or the Selling Stockholder (the "indemnifying
party") pursuant to the foregoing paragraph, such indemnified party or parties
shall promptly notify the indemnifying party or parties in writing of the
institution of such action (but the failure so to notify shall not relieve the
indemnifying party or parties from any liability they may have other than
pursuant to this Section 6(a), and the indemnifying party or parties shall
promptly assume the defense of such action, including the employment of counsel
(satisfactory to such indemnified party or parties) and payment of expenses.
Such indemnified party or parties shall have the right to employ its or their
own counsel in any such case, but the fees and expenses of such counsel shall be
at the expense of such indemnified party or parties unless the employment of
such counsel shall have been authorized in writing by the indemnifying party or
parties in connection with the defense of such action or the indemnifying party
or parties shall not have promptly employed counsel satisfactory to such
indemnified party or parties to have charge of the defense of such action or
such indemnified party or parties shall have reasonably concluded that there may
be one or more legal defenses available to it or them or to other indemnified
parties which are different from or additional to those available to the
indemnifying party or parties, in any of which events such fees and expenses
shall be borne by the indemnifying party or parties which shall not have the
right to direct the defense of such action on behalf of the indemnified party or
parties. Anything in this paragraph to the contrary notwithstanding, the
indemnifying party or parties shall not be liable for any settlement of any such
claim or action effected without its or their written consent; provided,
however, if a settlement is reached with such consent or if there is a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. The Company and the Selling Stockholder each agrees
promptly to notify the Underwriters and the Representative of the commencement
of any litigation or proceedings against the Company or the Selling Stockholder,
respectively, or against any of their officers or directors in connection
with the sale of the Shares, any Preliminary Prospectus, the Registration
Statement, or the Prospectus, or any amendment or supplement thereto, or any
application. To the extent any provision of this Section 6(a) entities the
indemnified party to reimbursement of fees and expenses, such obligations may be
billed by the indemnified party monthly and shall be due and payable within 10
days of the date thereof.
 
     (b) The Underwriters severally agree to indemnify and hold harmless the
Company, each director of the Company, each officer of the Company who shall
have signed the Registration Statement, each other person, if any, who controls
the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of
the Exchange Act, and the Selling Stockholder to the same extent as the
foregoing indemnity from the Company to the Underwriters in Section 6(a), but
only with respect to statements or omissions, if any, made in any Preliminary
Prospectus, the Registration Statement, or the Prospectus (as from time to time
amended and supplemented), or any amendment or supplement thereto, or in any
application, in reliance upon and in conformity with written information
furnished to the Company as stated in this Section 6(b) with respect to the
Underwriters by or on behalf of the Underwriters expressly for inclusion in any
Preliminary Prospectus, the Registration Statement, or the Prospectus, or any
amendment or supplement thereto, or in any application, as the case may be;
provided, however, that the obligation of the Underwriters to provide indemnity
under the provisions of this Section 6(b) shall be limited to the amount which
represents the product of the number of Shares sold hereunder and the initial
public offering price per Share set forth on the cover page of the Prospectus.
For all purposes of this Agreement, the amounts of the selling concession and
reallowance set
 
                                       21
   23
 
forth in the Prospectus and the information under "UNDERWRITING" constitute the
only information furnished in writing by or on behalf of the Underwriters
expressly for inclusion in any Preliminary Prospectus, the Registration
Statement, or the Prospectus (as from time to time amended or supplemented), or
any amendment or supplement thereto, or in any application, as the case may be.
If any action shall be brought against the Company, the Selling Stockholder or
any other person so indemnified based on any Preliminary Prospectus, the
Registration Statement, or the Prospectus, or any amendment or supplement
thereto, or any application, and in respect of which indemnity may be sought
against the Underwriters pursuant to this Section 6(b), the Underwriters shall
have the rights and duties given to the Company, and the Company, the Selling
Stockholder and each other person so indemnified shall have the rights and
duties given to the indemnified parties, by the provisions of Section 6(a).
 
SECTION 7.  CONTRIBUTION.
 
     In order to provide for just and equitable contribution in circumstances in
which the indemnity agreement provided for in Section 6 is for any reason held
to be unavailable to the Underwriters, the Company or the Selling Stockholder,
then the Company and the Selling Stockholder shall contribute to the damages
paid by the several Underwriters, and the several Underwriters shall contribute
to the damages paid by the Company and the Selling Stockholder; provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. In
determining the amount of contribution to which the respective parties are
entitled, there shall be considered the relative benefits received by each party
from the offering of the Shares (taking into account the portion of the proceeds
of the offering realized by each), the parties' relative knowledge and access to
information concerning the matter with respect to which the claim was asserted,
the opportunity to correct and prevent any statement or omission, and any other
equitable considerations appropriate in the circumstances. The Company, the
Selling Stockholder and the Underwriters agree that it would not be equitable if
the amount of such contribution were determined by pro rata or per capita
allocation (even if the Underwriters were treated as one entity for such
purpose). No Underwriter or person controlling such Underwriter shall be
obligated to make contribution hereunder which in the aggregate exceeds the
total public offering price of the Shares purchased by such Underwriter under
this Agreement, less the aggregate amount of any damages which such Underwriter
and its controlling persons have otherwise been required to pay in respect of
the same or any substantially similar claim. The Selling Stockholder shall not
be obligated to contribute any amount in excess of the amount by which the
product of the purchase price per share of Common stock, as set forth in Section
2 hereof, and the number of shares of common stock being sold by the Selling
Stockholder exceeds the amount of damages which the Selling Stockholder has
otherwise been required to pay in respect of the same or any substantially
similar claim. The Underwriters' obligations to contribute hereunder are several
in proportion to their respective underwriting obligations and not joint. For
purposes of this Section 7, each person, if any, who controls an Underwriter
within the meaning of Section 15 of the 1933 Act shall have the same rights to
contribution as such Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement, and each person, if any,
who controls the Company within the meaning of Section 15 of the 1933 Act, shall
have the same rights to contribution as the Company. Anything in this Section 7
contrary notwithstanding, no party shall be liable for contribution with respect
to the settlement of any claim or action entered without its written consent;
provided however, if a settlement is reached with such consent or if there is a
final judgment for the plaintiff, the party liable to make contribution agrees
to so contribute b), reason of such settlement or judgment to the extent
provided in this Section 7. This Section 7 is intended to supersede any right to
contribution under the 1933 Act, the 1934 Act, or otherwise.
 
SECTION 8.  REPRESENTATION, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.
 
     The representations, warranties, indemnities, agreements and other
statements of the Company, its officers and the Selling Stockholder set forth in
or made pursuant to this Agreement shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of the Company and
the Selling Stockholder or any Underwriter or controlling person and will
survive delivery of and payment for the Shares.

SECTION 9.  EFFECTIVE DATE OF THIS AGREEMENT AND TERMINATION OF AGREEMENT.
 
     (a) This Agreement shall become effective at 6:30 a.m. Pacific Time, on the
first full business day following the day on which the Registration Statement
becomes effective or at the time of the initial public offering of the Shares,
whichever is earlier. The time of the initial public offering shall mean the
time, after the Registration Statement becomes effective, of the release by you
for publication of the first newspaper advertisement which is subsequently
published relating to the Shares or the time, alter the Registration Statement
becomes effective, when the Shares are first released by you for offering by
dealers by letter or telegram, whichever shall first occur. You or the Company
may prevent this Agreement from becoming effective without liability of any
party to any other party, except as noted below in this Section 9, by giving the
notice indicated in Section 9(c) before the time this Agreement becomes
effective.
 
     (b) You shall have the right to terminate this Agreement at any time prior
to the Closing Date by giving notice to the Company and the Selling Stockholder
(i) if there has been, since the date as of which the information is given in
the Prospectus, any Material Adverse Change, whether or not arising in the
ordinary course of business; (ii) if there has occurred any material adverse
change in the financial markets in the United States or internationally or any
outbreak of hostilities or escalation of existing hostilities or other calamity
or crisis the effect of which is such as to make it, in your reasonable
judgment, impracticable to market the Shares or enforce contracts for the sale
of the Shares; (iii) if trading in any securities of the Company has been
suspended by the Commission, or if trading generally on either the American
Stock Exchange or the New York Stock Exchange or in the over-the-counter market
has been suspended, or minimum or maximum prices for trading have been fixed, or
maximum ranges for prices for securities have been required, by either of such
Exchanges or by order of the Commission, any other governmental authority or the
NASD; (iv) if a banking moratorium has been declared by either federal, Arizona,
Nevada or New York authorities; (v) if there has occurred any change or
development involving a prospective change in national or international
political financial or economic controls, which in your opinion is likely to
have a material adverse effect on the market for the Shares; or (vi) any event
occurs affecting the condition of the Company or the Significant Subsidiaries
which, in your judgment, renders the sale of the Shares provided for herein
undesirable, impractical, or inadvisable. As used in this Section 9(a), the term
"Prospectus" means the Prospectus in the form first used to confirm sales of the
Shares.
 
     (c) If you elect to prevent this Agreement from becoming effective as
provided in this Section 9, or to terminate this Agreement, you shall notify the
Company and the Selling Stockholder, promptly by telephone, telex or telegram,
confirmed by letter. If, as so provided, the Company elects to prevent this
Agreement from becoming effective, the Company shall notify you and the Selling
Stockholder by telephone, telex or telegram, confirmed by letter.
 
     (d) Notwithstanding any election hereunder or any termination of this
Agreement, and whether or not this Agreement is otherwise carried out, the
provisions of Section 3(a), 4, 6, 7, 8 and 9 shall not be in any way affected by
such election or termination or failure to carry out the terms of this Agreement
or any part hereof.
 
     (e) This Agreement may also terminate pursuant to the provisions of Section
2(c) and Section 5, with the effect stated in such Sections.
 
SECTION 10.  DEFAULT BY ONE OR MORE OF THE UNDERWRITERS.
 
     If for any reason one or more Underwriters shall fail or refuse (otherwise
than for a reason sufficient to justify the termination of this Agreement under
the provisions of Section 9 hereof to purchase and pay for the number of Shares
agreed to be purchased by such Underwriter, the Company or the Selling
Stockholder shall immediately give notice thereof to you, and the non-defaulting
Underwriters shall have the fight within 24 hours after the receipt by you of
such notice, to purchase or procure one or more other Underwriters to purchase,
in such proportions as may be agreed upon among you and such purchasing
Underwriter or Underwriters and upon the terms herein set forth, the Shares that
such defaulting Underwriter or Underwriters agreed to purchase. If the
non-defaulting Underwriters fail so to make such arrangements with respect to
all such shares, the number of Shares which each non-defaulting Underwriter is
otherwise obligated to purchase under the Agreement shall be automatically
increased pro rata to absorb the remaining Shares that
 
                                       23
   25
 
the defaulting Underwriter or Underwriters agreed to purchase; provided,
however, that the non-defaulting Underwriters shall not be obligated to purchase
the Shares that the defaulting Underwriter or Underwriters agreed to purchase in
excess of 10% of the total number of Shares that such non-defaulting Underwriter
agreed to purchase hereunder, and provided, further, that the non-defaulting
Underwriters shall not be obligated to purchase any Shares that the defaulting
Underwriter or Underwriters agreed to purchase if such additional purchase would
cause the Underwriter to be in violation of the net capital rule of the
Commission or other applicable law. If the total number of Shares that the
defaulting Underwriter or Underwriters agreed to purchase shall not be purchased
or absorbed in accordance with the two preceding sentences, the Selling
Stockholder shall have the right, within 24 hours next succeeding the 24-hour
period above referred to, to make arrangements with other underwriters or
purchasers satisfactory to you for the purchase of such Shares on the terms
herein set forth. In any such case, either you or the Selling Stockholder shall
have the right to postpone each Closing for not more than seven business days
after the date originally fixed as such Closing in order that any necessary
changes in the Registration Statement, the Prospectus or any other documents or
arrangements may be made. As used herein, the term "Underwriter" includes any
person substituted for an Underwriter under this Section 10. If neither the
non-defaulting Underwriters nor the Selling Stockholder shall make arrangements
within the 24-hour periods stated above for the purchase of all the Shares that
the defaulting Underwriter or Underwriters agreed to purchase hereunder, this
Agreement shall be terminated without further act or deed and without any
liability on the pan of the Company or the Selling Stockholder to any
non-defaulting Underwriter.
 
     Nothing contained herein shall relieve any defaulting Underwriter of its
liability, if any, to the Selling Stockholder or to the remaining Underwriters
for damages occasioned by its default hereunder.
 
SECTION 11.  DEFAULT BY THE SELLING STOCKHOLDER.
 
     If the Selling Stockholder shall fail at either Closing Date to sell and
deliver the number of Shares that she is obligated to sell, then this Agreement
shall terminate without any liability on the part of any non-defaulting party
except to the extent provided in Section 4 and except that the provisions of
Sections 7 and 8 shall remain in effect. No action taken pursuant to this
Section shall relieve the Selling Stockholder from liability, if any, in respect
of such default.
 
SECTION 12.  NOTICES.
 
     All notices and other communications under this Agreement shall be in
writing and shall be deemed to have been duly given if delivered, mailed or
transmitted by any standard form of telecommunication (notices transmitted by

administrators, successors and assigns and, subject to the provisions of Section
10, no other person shall acquire or have any fight under or by virtue of this

obligations of the Underwriters hereunder are several and not joint.
