with the Commission pursuant to Rule 424(b) and Rule 430A under the Act or, if
no prospectus is required to be filed pursuant to said Rule 424(b), such term
means the prospectus included in the Registration Statement.

         several Underwriters an option to purchase, severally and not jointly,
         the Option Securities. The purchase price to be paid for any Option
         Securities shall be the same price per share as the price per share for

         plus if the purchase and sale of any Option Securities takes place
         after the Firm Closing Date and after the Firm Securities are trading
         "ex-dividend," an amount equal to the dividend payable on such Option
         Securities. The option granted hereby may be exercised as to all or any
         part of the Option Securities from time to time within



 
                                        8

         Option Securities shall be sold and delivered unless the Firm
         Securities previously have been, or simultaneously are, sold and
         delivered. The Underwriters shall not be under any obligation to
         purchase any of the Option Securities prior to the exercise of such
         option. The Representatives may from time to time exercise the option
         granted hereby by giving notice in writing or by telephone (confirmed
         in writing) to the Company setting forth the aggregate number of shares
         of Option Securities as to which the several Underwriters are then
         exercising the option and the date and time for delivery of and payment
         for such Option Securities. Any such date of delivery shall be
         determined by the Representatives but shall not be earlier than two
         business days or later than seven business days after such exercise of
         the option and, in any event, shall not be earlier than the Firm
         Closing Date. The time and date set forth in such notice, or such other
         time on such other date as the Representatives and the Company may
         agree upon or as the Representatives may determine pursuant to Section
         9 hereof, is herein called the "Option Closing Date" with respect to
         such Option Securities. Upon exercise of the option as provided herein,
         the Company shall become obligated to sell to each of the several
         Underwriters, and, subject to the terms and conditions herein set
         forth, each of the Underwriters (severally and not jointly) shall
         become obligated to purchase from the Company, the same percentage of
         the total number of the Option Securities as to which the several
         Underwriters are then exercising the option as such Underwriter is
         obligated to purchase of the aggregate number of Firm Securities, as
         adjusted by the Representatives in such manner as the Representatives
         deems advisable to avoid fractional shares. If the option is exercised
         as to all or any portion of the Option Securities, one or more
         certificates in definitive form for such Option Securities, and payment
         therefor, shall be delivered on the related Option Closing Date in the
         manner, and upon the terms and conditions, set forth in paragraph (a)
         of this Section 3.

                  (c) It is understood that you, individually and not as the
         Representatives, may (but shall not be obligated to) make payment on
         behalf of any Underwriter or Underwriters for any of the Securities to
         be purchased by such Underwriter or Underwriters. No such payment shall
         relieve such Underwriter or Underwriters from any of its or their
         obligations hereunder.

         4. Offering by the Underwriters. Upon your authorization of the release
of the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.
The Representatives shall promptly advise the Company of the commencement of the
public offering.

         5. Covenants of the Company. The Company covenants and agrees with each
of the Underwriters that:

                  (a) Subject to the next sentence, the Company will file the
         Prospectus with the Commission pursuant to Rule 424 under the Act.
         During any time when a prospectus relating to the Securities is
         required to be delivered under the Act, the Company (i) will comply
         with all requirements imposed upon it by the Act and the Exchange Act
         and the respective rules and regulations of the Commission thereunder
         to the extent necessary to permit the continuance of sales of or
         dealings in the Securities in accordance with the provisions hereof and
         of the Prospectus, as then amended or supplemented, and (ii) will not



 
                                        9
   10
         file with the Commission the Prospectus, any amendment or supplement to
         the Prospectus, or any amendment to the Registration Statement, of
         which the Representatives shall not previously have been advised and
         furnished with a copy a reasonable period of time prior to the proposed
         filing and as to which filing the Representatives shall not have given
         their consent, which consent will not be unreasonably withheld. The
         Company will advise the Representatives, promptly after receiving
         notice thereof, of the time when (i) the Prospectus has been filed with
         the Commission and (ii) any amendment to the Registration Statement has
         been filed or declared effective or any amendment or supplement to the
         Prospectus has been filed and will provide evidence satisfactory to the
         Representatives of each such filing or effectiveness.

                  (b) The Company will advise the Representatives, promptly
         after receiving notice or obtaining knowledge thereof, of (i) the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or any post-effective
         amendment thereto or any order directed at any document incorporated by
         reference in the Registration Statement or the Prospectus or any
         amendment or supplement thereto or any order preventing or suspending
         the use of the Prospectus, (ii) the suspension of the qualification of
         the Securities for offering or sale in any jurisdiction, (iii) the
         institution, threatening or contemplation of any proceeding for any
         such purpose or (iv) any request made by the Commission for amending
         the Registration Statement, for amending or supplementing the
         Prospectus or for additional information. The Company will use its best
         efforts to prevent the issuance of any such stop order and, if any such
         stop order is issued, to obtain the withdrawal thereof as promptly as
         possible.

                  (c) The Company will cooperate with the Representatives in
         connection with the registration or qualification of the Securities for
         offering and sale under the securities or blue sky laws of such
         jurisdictions as the Representatives may designate and will continue
         such qualifications in effect for as long as may be reasonably
         necessary to complete the distribution of the Securities, provided,
         however, that in connection therewith the Company shall not be required
         to qualify as a foreign corporation or to execute a general consent to
         service of process in any jurisdiction.

                  (d) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus, as then amended or supplemented,
         would include any 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, or if for any other reason it is necessary at any time to
         amend or supplement the Prospectus to comply with the Act, the Exchange
         Act or the respective rules or regulations of the Commission
         thereunder, the Company will promptly notify the Representatives
         thereof and, subject to Section 5(a) hereof, will prepare and file with
         the Commission, at the Company's expense, an amendment to the
         Registration Statement or an amendment or supplement to the Prospectus
         that corrects such statement or omission or effects such compliance.

                  (e) The Company will, without charge, provide to the
         Representatives and to counsel for the Underwriters a signed copy of
         the Registration Statement originally filed with respect to the
         Securities and each amendment thereto (in each case including exhibits



 
                                       10
   11
         thereto), (ii) to each Underwriter, a conformed copy of such
         Registration Statement and each amendment thereto (in each case without
         exhibits thereto) and (iii) as long as a prospectus relating to the
         Securities is required to be delivered under the Act, as many copies of
         each Preliminary Prospectus or the Prospectus or any amendment or
         supplement thereto as the Representatives may reasonably request.

                  (f) The Company, as soon as practicable, will make generally
         available to its security holders and to the Representatives a
         consolidated earnings statement of the Company and its subsidiaries
         covering a period of at least 12 months after the effective date of the
         Registration Statement (but in no event commencing later than 90 days
         after such date), which statement shall satisfy the provisions of
         Section 11(a) of the Act and Rule 158 thereunder.

                  (g) The Company will apply the net proceeds from the sale of
         the Company's Securities as set forth under "Use of Proceeds" in the
         Prospectus.

                  (h) The Company, its directors and executive officers will
         not, directly or indirectly, without the prior written consent of the
         Representatives, on behalf of the Underwriters, offer, issue, sell,
         contract to sell, grant any option to purchase or otherwise dispose of
         (or announce any offer, issuance, sale, grant of any option to purchase
         or other disposition of) any shares of Common Stock or any securities
         convertible into, or exchangeable or exercisable for, shares of Common
         Stock for a period of 90 days from the date of the Prospectus, except
         pursuant to this Agreement and except grants of option under stock
         option plans described in the Prospectus and issuances of shares of
         Common Stock (x) pursuant to the exercise of stock options under stock
         options plans or compensation contracts described in the Prospectus or
         (y) in connection with the acquisition of assets by the Company or its
         subsidiaries as described in the Prospectus.

                  (i) For a period of 60 days after the effective date of the
         Registration Statement, the Company will not (i) take, directly or
         indirectly, any action designed to cause or to result in, or that might
         reasonably be expected to constitute, the stabilization or manipulation
         of the price of any security of the Company to facilitate the sale or
         resale of the Securities or (ii) bid for, purchase, attempt to induce
         any person to purchase, or pay anyone any compensation for soliciting
         purchases of, the Securities or (iii) pay or agree to pay to any person
         any compensation for soliciting another to purchase any other
         securities of the Company.

                  (j) The Company will file with the NYSE, as long as its
         securities are quoted thereon, all documents and notices required by
         the NYSE of companies that have issued securities that are traded on
         the NYSE.

                  (k) If at any time during the 25-day period after the
         Registration Statement becomes effective, any rumor, publication or
         event relating to or affecting the Company shall occur as a result of
         which in your opinion the market price of the Common Stock has been or
         is likely to be materially affected (regardless of whether such rumor,
         publication or event necessitates a supplement to or amendment to the
         Prospectus), the Company will, after written notice from you advising
         the Company to the effect set forth above, forthwith



 
                                       11
   12
         prepare, consult with you concerning the substance of, and disseminate
         a press release or other public statement, reasonably satisfactory to
         you, responding to or commenting on such rumor, publication or event.

                  (l) For five years after the date hereof, the Company will
         mail as soon as practicable to the holders of its Common Stock and
         Convertible Exchangeable Preferred Stock substantially all of the
         following documents, which documents shall be in compliance with this
         Section if they are in the form prescribed by the Exchange Act:

                                    (i) within 75 days after the end of the
                           first three quarters of each fiscal year, copies of
                           the quarterly unaudited condensed consolidated

                           be opined to by a nationally recognized firm of
                           independent public accountants in such form as to

                           condition and the consolidated results of its
                           operations for such fiscal year.

                  (m) For five years after the date hereof, the Company will
         furnish to the Representatives (i) concurrently with furnishing such
         reports to its shareholders, the reports described in Section 5(l)
         hereof; (ii) as soon as they are available, copies of all other reports

         be on a consolidated basis to the extent that the accounts of the
         Company and any subsidiary or subsidiaries are consolidated and shall
         be accompanied by similar financial statements for any significant
         subsidiary which is not so consolidated.

                  (n) For a period of at least three years after the effective
         date of the Registration Statement, the Company will continue to file
         with the Commission all reports and other documents as may be required

                  Company or any of its subsidiaries is a party or to which any
                  property of any of them is subject that, if determined
                  adversely to the Company or any subsidiary, would have a
                  material adverse effect on the Company and its subsidiaries
                  taken as a whole, nor has such counsel become aware of a
                  threat of any such proceedings by governmental authorities or
                  others, nor is such counsel aware of any 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 (except that such counsel need not
                  express any belief, comment or opinion as to the financial
                  statements, notes or schedules or other financial or
                  statistical data or information in the Registration Statement
                  or the Prospectus), and such contracts and documents as are
                  summarized in the Registration Statement or the Prospectus are
                  fairly summarized in all material respects;

                           (viii) the compliance by the Company with the
                  provisions of this Agreement and the consummation of the
                  transactions herein contemplated do not (A) require the
                  consent, approval, authorization, registration or
                  qualification of or with any governmental authority, except
                  such as have been obtained and such as may be required under
                  state securities or blue sky laws or applicable regulations of
                  the NASD or (B) conflict with or result in a material breach
                  or violation of any of the terms and provisions of, or
                  constitute a default under, (1) any indenture, mortgage, deed
                  of trust, lease or other agreement or instrument, known to
                  such counsel, to which the Company or any of its subsidiaries
                  is a party or by which the Company or any of its subsidiaries
                  or any of their respective properties are bound, (2) the
                  articles of incorporation or bylaws of the Company or any of
                  the Subsidiaries, (3) any statute, rule or regulation or (4)
                  any judgment, decree or order of any court or other
                  governmental authority or any arbitrator known to such counsel
                  and applicable to the Company or any of its subsidiaries;

                           (ix) other than as described in the Registration
                  Statement or the Prospectus, in the course of such counsel's
                  engagement to represent the Company and any of its
                  subsidiaries professionally, such counsel has not become aware
                  that any subsidiary of the Company is currently prohibited,
                  directly or indirectly, from paying any dividends to the
                  Company, from making any other distribution on such
                  subsidiary's capital stock, from repaying to the Company any
                  loans or advances to such subsidiary from the Company, or from
                  transferring any of such subsidiary's property or assets to
                  the Company or any other subsidiary of the Company;

                           (x) other than as disclosed in the Registration
                  Statement or the Prospectus, in the course of such counsel's
                  engagement to represent the Company and any of its
                  subsidiaries professionally, such counsel has not become aware
                  that the Company or any of its subsidiaries are in default, or
                  that any event has occurred which with the giving of notice or
                  the lapse of time or both would constitute such a default,
                  with respect to any statute, order, rule, regulation,
                  indenture, mortgage, deed of trust,

                  note agreement or other agreement or instrument certified by
                  the Company to such counsel as material to the Company (and
                  such counsel advises the Representatives that they are not
                  aware of any other material agreements or instruments to which
                  the Company or any of its subsidiaries is a party or by which
                  any of them is bound) and where such default would expose the
                  Company and the subsidiaries, taken as a whole, to substantial
                  monetary damages or penalties or would otherwise have a
                  material adverse effect on the Company and its subsidiaries,
                  taken as a whole;

                           (xi) the Registration Statement has become effective
                  under the Act; any required filing of the Prospectus and any
                  Preliminary Prospectus pursuant to Rule 424(b) has been made
                  in the manner and within the time period required by Rule
                  424(b); and no stop order suspending the effectiveness of the
                  Registration Statement or any post-effective amendment thereto
                  has been issued, and to such counsel's best knowledge no
                  proceedings for that purpose have been instituted or
                  threatened or are contemplated by the Commission; and

                           (xii) the registration statement originally filed
                  with respect to the Securities and each amendment thereto and
                  the Prospectus (not including the financial statements, notes,
                  schedules or other financial and statistical data or
                  information contained therein, as to which such counsel need
                  express no opinion), as of its respective effective or issue
                  date, as applicable, on its face complied as to form in all
                  material respects with the applicable requirements of the Act
                  and the Exchange Act and the respective rules and regulations
                  of the Commission thereunder.

                           (xiii) the Company has filed with the Commission a
                  Registration Statement on Form 8-A which has become effective
                  under the Exchange Act with respect to the Common Stock.

Such counsel shall also state that they have participated in conferences with
officers of the Company, the independent accountants for the Company, and
counsel for and the Representatives of the Underwriters in connection with the
preparation of the Registration Statement and Prospectus and have considered the
matters required to be stated therein and the statements contained or
incorporated by reference therein, although such counsel shall not be required
to have independently verified the accuracy, completeness or fairness of such
statements. Such counsel shall advise the Representatives that, on the basis of
the foregoing, no facts have come to such counsel's attention that have caused
such counsel to believe that the Registration Statement (exclusive of the
financial statements, notes and schedules and other financial and statistical
information or data included therein, as to which such counsel need express no
belief or comment), at the time it became effective or at the time of any
post-effective amendment thereto, contained an untrue statement of a material
fact or omitted to state a 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, or that the Prospectus (exclusive of the
financial statements, notes and schedules and other financial and statistical
information or data included therein, as to which such counsel need express no
belief or comment), on the date thereof or as of the Firm Closing Date,
contained or contains an untrue statement of material fact or omitted or omits
to state a 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 rendering such opinion, such counsel may rely (A) as to matters of
fact, to the extent such counsel deems proper, on certificates of executive
officers of the Company and public officials, and (B) as to matters involving
the application of laws of any jurisdiction other than the State of Arizona and
the United States, to the extent satisfactory in form and scope to counsel for
the Underwriters, upon the opinion of local counsel for the Company.

         References to the Registration Statement and the Prospectus in this
paragraph (b) shall include any amendment or supplement thereto at the date of
such opinion.

                  (c) The Representatives shall have received an opinion, dated
         the Firm Closing Date, of O'Connor, Cavanagh, Anderson, Killingsworth &
         Beshears, a professional association, counsel for the Underwriters,
         with respect to the issuance and sale of the Firm Securities, the
         Registration Statement and the Prospectus, and such other related
         matters as the Representatives may reasonably require, and the Company
         shall have furnished to such counsel such documents as they may
         reasonably request for the purpose of enabling them to pass upon such
         matters.

                  (d) The Representatives shall have received from Deloitte &
         Touche LLP a letter or letters dated, respectively, the date hereof and
         the Firm Closing Date, in form and substance satisfactory to the
         Representatives, to the effect that:

                           (i) they are independent accountants with respect to
                  the Company and its subsidiaries within the meaning of the
                  Act, the Exchange Act and the applicable rules and regulations
                  thereunder;

                           (ii) in their opinion, the audited consolidated
                  financial statements and schedules examined by them and
                  included and incorporated by reference in the Registration
                  Statement and the Prospectus comply in form in all material
                  respects with the applicable accounting requirements of the
                  Act and the related published rules and regulations
                  thereunder;

                           (iii) on the basis of a reading of the latest
                  available unaudited consolidated financial statements of the
                  Company and its consolidated subsidiaries, carrying out
                  certain specified procedures (which do not constitute an
                  examination made in accordance with generally accepted
                  auditing standards) that would not necessarily reveal matters
                  of significance with respect to the comments set forth in this
                  paragraph (iii), a reading of the minute books of the
                  shareholders, the board of directors and any committees
                  thereof of the Company and each of its consolidated
                  subsidiaries, and inquiries of certain officials of the
                  Company and its consolidated subsidiaries who have
                  responsibility for financial and accounting matters, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited consolidated financial
                           statements of the Company and its subsidiaries
                           included and incorporated by reference in the
                           Registration Statement and the Prospectus do not
                           comply in form in all material respects with the
                           applicable accounting requirements of the Act, the
                           Exchange Act and the related published rules and
                           regulations thereunder, or



 
                                       17
   18
                           are not in conformity with generally accepted
                           accounting principles applied on a basis
                           substantially consistent with that of the audited
                           consolidated financial statements included and
                           incorporated by reference in the Registration
                           Statement and the Prospectus; and

                                    (B) at a specific date not more than five
                           business days prior to the date of such letter, there
                           were any changes in the capital stock or long-term
                           debt of the Company and its consolidated subsidiaries
                           or any decreases in total assets, net current assets
                           or shareholders' equity of the Company and its
                           consolidated subsidiaries, in each case compared with
                           amounts shown on the December 31, 1996 audited
                           consolidated balance sheet included and incorporated
                           by reference in the Registration Statement and the
                           Prospectus, or for the period from January 1, 1997 to
                           such specified date there were any decreases, as
                           compared with the comparable period commencing
                           January 1, 1996, in revenues, income from operations,
                           net income or net income per common share, of the
                           Company and its consolidated subsidiaries, except in
                           all instances for changes, decreases or increases set
                           forth in such letter or in the Registration
                           Statement; and

                                    (iv) they have carried out certain specified
                           procedures, not constituting an audit, with respect
                           to certain amounts, percentages and financial
                           information that are derived from the general
                           accounting records of the Company and its
                           consolidated subsidiaries and are included in the
                           Registration Statement and the Prospectus under the
                           captions "Prospectus Summary," "Use of Proceeds,"
                           "Capitalization," "Selected Consolidated Financial
                           Data," "Management's Discussion and Analysis of
                           Financial Condition and Results of Operations,"

                           "Description of Securities" and "Shares Eligible for
                           Future Sale," and have compared such amounts,
                           percentages and financial information with such
                           records of the Company and its consolidated
                           subsidiaries and with information derived from such
                           records and have found them to be in agreement,
                           excluding any questions of legal interpretation;

                                    (v) although they are unable to and do not
                           express an opinion on the unaudited pro forma
                           condensed earnings information (the "Pro Forma
                           Earnings Information") included in the Registration
                           Statement or the Prospectus, they have (A) read the
                           Pro Forma Earnings Information, (B) made inquiries of
                           certain officials of the Company who have
                           responsibility for financial and accounting matters
                           about the basis for their determination of the pro
                           forma adjustments to the historical amounts in the
                           Pro Forma Earnings Information and whether the Pro
                           Forma Earnings Information comply in form in all
                           material respects with the applicable accounting
                           requirements of Rule 11-02 of Regulation S-X; and (C)
                           proved the arithmetic accuracy of the application of
                           the pro forma adjustments to the historical amounts
                           in the Pro Forma Earnings Information; on the basis
                           of such procedures, and such other inquiries and
                           procedures as may be specified in such letter,
                           nothing came to their attention that caused them to
                           believe that



 
                                       18
   19
                           the Pro Forma Earnings Information do not comply in
                           form in all material respects with the applicable
                           requirements of Rule 11-02 of Regulation S-X and that
                           the pro forma adjustments have not been properly
                           applied to the historical amounts in the compilation
                           of such statements.

         In the event that the letters referred to above set forth any such
changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (A) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

                  References to the Registration Statement and the Prospectus in
         this paragraph (d) with respect to either letter referred to above
         shall include any amendment or supplement thereto at the date of such
         letter.

                  (e) The Representatives shall have received a certificate,
         dated the Firm Closing Date, of the President and the Chief Financial
         Officer of the Company to the effect that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct as if made on and as of

                  as of the Firm Closing Date, does not include any untrue
                  statement of a material fact or omit to state any material
                  fact necessary to make the statements therein, in light of the
                  circumstances under which they were made, not misleading, and
                  the Prospectus, as amended or supplemented as of the Firm
                  Closing Date, does not include any untrue statement of a
                  material fact or omit to state any material fact necessary in
                  order to make the statements therein, in light of the
                  circumstances under which they were made, not misleading; and
                  the Company has performed all covenants and agreements and
                  satisfied all conditions on its part to be performed or
                  satisfied under this Agreement at or prior to the Firm Closing
                  Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement or any post-effective amendment
                  thereto and no order directed at any document incorporated by
                  reference in the Registration Statement or the Prospectus, has
                  been issued, and no proceedings for that purpose have been
                  instituted or threatened or, to the best of the Company's
                  knowledge, are contemplated by the Commission; and

                           (iii) subsequent to the respective dates as of which
                  information is given in the Registration Statement and the
                  Prospectus, the Company and its subsidiaries, taken as a
                  whole, have not sustained any material loss or interference
                  with their respective businesses or properties from fire,
                  flood, hurricane, accident or other calamity, whether or not
                  covered by insurance, or from any labor dispute or any legal
                  or governmental proceeding, and there has not been any
                  material adverse change, or any development reasonably likely
                  to result in a material adverse change, in the condition
                  (financial or otherwise), business prospects, net worth or
                  results of operations of the Company and its subsidiaries,
                  except in each case as described in



 
                                       19
   20
                  or contemplated by the Prospectus (exclusive of any amendment
                  or supplement thereto after the date hereof).

                  (f) The Representatives shall have received from each
         executive officer and each director of the Company an agreement to the
         effect that such person will not, directly or indirectly without the
         prior written consent of the Representatives of the Underwriters,
         offer, sell contract to sell, grant any option to purchase or otherwise
         dispose of (or announce any offer, sale, grant of an option to purchase
         or other disposition of) any shares of Common Stock or any securities
         convertible into, or exchangeable or exercisable for shares of Common
         Stock prior to 90 days from the date of the Prospectus.

                  (g) On or before the Firm Closing Date, the Representatives
         and counsel for the Underwriters shall have received such further
         certificates, documents or other information as they may have
         reasonably requested from the Company.

         All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Underwriters. The Company shall furnish to the Representatives
such conformed copies of such opinions, certificates, letters and documents in
such quantities as the Representatives and counsel for the Underwriters shall
reasonably request.

         The respective obligations of the several Underwriters to purchase and
pay for any Option Securities shall be subject, in their discretion, to each of
the foregoing conditions to purchase the Firm Securities, except that all
references to (i) the Firm Securities and (ii) the Firm Closing Date shall be
deemed to refer to (i) such Option Securities and (ii) the related Option
Closing Date, respectively.

         8.       Indemnification and Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls any Underwriter
         within the meaning of the Act against any losses, claims, damages or
         liabilities to which such Underwriter or such controlling person may
         become subject under the Act or otherwise, insofar as such losses,
         claims, damages or liabilities (or actions or proceedings in respect
         thereof) arise out of or are based upon (i) any untrue statement or
         alleged untrue statement of any material fact contained in the
         Registration Statement, any Preliminary Prospectus, the Prospectus or
         any amendment or supplement thereto or any application or other
         document (or amendment or supplement thereto) executed by the Company
         filed in any jurisdiction to qualify the Securities under the
         securities or blue sky laws thereof or filed with the Commission or any
         securities association or exchange, or (ii) the omission or alleged
         omission to state in the Registration Statement, any Preliminary
         Prospectus, the Prospectus or any amendment or supplement thereto, a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, and will reimburse, as incurred,
         each Underwriter and each such controlling person for any legal or
         other expenses reasonably incurred by such Underwriter or such
         controlling person in connection with investigating, defending or
         appearing as a third party witness in connection with any such loss,
         claim, damage, liability, action or proceeding; provided, however, that
         the Company will not be liable in any such case to the extent that



 
                                       20
   21
         any such loss, claim, damage or liability arises out of or is based
         upon an untrue statement or alleged untrue statement, or omission or
         alleged omission made in the Registration Statement, any Preliminary
         Prospectus, the Prospectus, or such amendment or supplement, in
         reliance upon and in conformity with written information furnished to
         the Company by or through the Representatives specifically for use in
         the preparation thereof. This indemnity agreement will be in addition
         to any liability which the Company may otherwise have.

                  (b) Each Underwriter will indemnify and hold harmless the
         Company, each of its directors, each of its officers who signed the
         Registration Statement, and each person, if any, who controls the
         Company within the meaning of Section 15 of the Act or Section 20 of
         the Exchange Act against any losses, claims, damages or liabilities to
         which the Company, any such director or officer of the Company, or any
         such controlling person of the Company may become subject under the
         Act, the Exchange Act or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions in respect thereof) arise out of or
         are based upon (i) any untrue statement or alleged untrue statement of
         any material fact contained in the Registration Statement or any
         amendment thereto, any Preliminary Prospectus or the Prospectus or any
         amendment or supplement thereto, or any Application or (ii) the
         omission or the alleged omission to state therein a material fact
         required to be stated in the Registration Statement or any amendment
         thereto, any Preliminary Prospectus or the Prospectus or any amendment
         or supplement thereto, or any Application or necessary to make the
         statements therein not misleading, in each case to the extent, but only
         to the extent, that such untrue statement or alleged untrue statement
         or omission or alleged omission was made in reliance upon and in
         conformity with written information furnished to the Company by any
         Underwriter through the Representatives specifically for use therein;
         and, subject to the limitation set forth immediately preceding this
         clause, will reimburse, as incurred, any legal or other expenses
         reasonably incurred by the Company, any such director, officer or
         controlling person in connection with investigating or defending or
         appearing as a third party witness in connection with any such loss,
         claim, damage, liability or any action in respect thereof. This
         indemnity agreement will be in addition to any liability which such
         Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
         Section 8 of notice of the commencement of any action, such indemnified
         party will, if a claim in respect thereof is to be made against the
         indemnifying party under this Section notify the indemnifying party of
         the commencement thereof; but the omission so to notify the
         indemnifying party will not relieve the indemnifying party from any
         liability which it may have to any indemnified party otherwise than
         under this Section 8. In case any such action is brought against any
         indemnified party, and it notifies the indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate therein and, to the extent that it may wish, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof, with counsel reasonably satisfactory to such indemnified
         party; provided, however, that if the defendants in any such action
         include both the indemnified party and the indemnifying party and the
         indemnified party shall have reasonably concluded that there may be one
         or more legal defenses available to it and/or other indemnified parties
         which are different from or additional to those available to the
         indemnifying party, the indemnifying party shall not have the right to
         direct the defense of such action on behalf of such indemnified party
         or parties



 
                                       21
   22
         and such indemnified party or parties shall have the right to select
         separate counsel, reasonably acceptable to the indemnifying party, to
         defend such action on behalf of such indemnified party or parties.
         After notice from the indemnifying party to such indemnified party of
         its election so to assume the defense thereof and approval by such
         indemnified party of counsel appointed to defend such action, the
         indemnifying party will not be liable to such indemnified party under
         this Section 8 for any legal or other expenses, other than reasonable
         costs of investigation, subsequently incurred by such indemnified party
         in connection with the defense thereof, unless (i) the indemnified
         party shall have employed separate counsel in accordance with the
         proviso to the next preceding sentence (it being understood, however,
         that in connection with such action the indemnifying party shall not be
         liable for the expenses of more than one separate counsel (in addition
         to local counsel) in any one action or separate but substantially
         similar actions in the same jurisdiction arising out of the same
         general allegations or circumstances, designated by the Representatives
         in the case of paragraph (a) of this Section 8 representing the
         indemnified parties under such paragraph (a) who are parties to such
         action or actions) or (ii) the indemnifying party has authorized in
         writing the employment of counsel for the indemnified party at the
         expense of the indemnifying party. After such notice from the
         indemnifying party to such indemnified party, the indemnifying party
         will not be liable for the costs and expenses of any settlement of such
         action effected by such indemnified party without the consent of the
         indemnifying party, unless such indemnified party waived its rights
         under this Section 8 in writing in which case the indemnified party may
         effect such a settlement without such consent.

                  (d) Only in circumstances in which the indemnity agreement
         provided for in the preceding paragraphs of this Section 8 is
         unavailable or insufficient to hold harmless an indemnified party in
         respect of any losses, claims, damages or liabilities (or actions in
         respect thereof), each indemnifying party, in order to provide for just
         and equitable contribution, shall contribute to the amount paid or
         payable to such indemnified party as a result of such losses, claims,
         damages or liabilities (or actions in respect thereof) in such
         proportion as is appropriate to reflect (i) the relative benefits
         received by the indemnifying party or parties on the one hand and the
         indemnified party on the other from the offering of the Securities or
         (ii) if the allocation provided by the foregoing clause (i) is not
         permitted by applicable law, not only such relative benefits but also
         the relative fault of the indemnifying party or parties on the one hand
         and the indemnified party on the other in connection with the
         statements or omissions or alleged statements or omissions that
         resulted in such losses, claims, damages or liabilities (or actions in
         respect thereof). The relative benefits received by the Company on the
         one hand and the Underwriters on the other shall be deemed to be in the
         same proportion as the total proceeds from the offering (before
         deducting expenses) received by the Company bear to the total
         underwriting discounts and commissions received by the Underwriters.
         The relative fault of the parties shall be determined by reference to,
         among other things, whether the untrue or alleged untrue statement of a
         material fact or the omission or alleged omission to state a material
         fact relates to information supplied by the Company or the
         Underwriters, the parties' relative intents, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission, and any other equitable considerations appropriate in the
         circumstances. The Company 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) or by any other method of allocation that
         does not take into account the equitable



 
                                       22
   23
         considerations referred to in the first sentence of this paragraph (d).
         Notwithstanding any other provision of this paragraph (d), no
         Underwriter shall be obligated to make contributions hereunder that in
         the aggregate exceed the total public offering price of the Securities
         purchased by such Underwriter under this Agreement under this Agreement
         less the aggregate amount of any damages that such Underwriter has
         otherwise been required to pay in respect of the same or any
         substantially similar claim, and no person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the Act)
         shall be entitled to contribution from any person who was not guilty of
         such fraudulent misrepresentation. The Underwriters' obligations to
         contribute hereunder are several in proportion to their respective
         underwriting obligations and not joint, and contributions among
         Underwriters shall be governed by the provisions of the Agreement Among
         Underwriters dated the date hereof among the Representatives and the
         other Underwriters. For purposes of this paragraph (d), each person, if
         any, who controls an Underwriter within the meaning of Section 15 of
         the Act or Section 20 of the Exchange 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 Act or Section 20 of the Exchange Act, shall have the
         same rights to contribution as the Company.

         9. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Securities or Option Securities hereunder and
the aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the nondefaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase. If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter, the Company other than as provided
in Section 10 hereof. In the event of any default by one or more Underwriters as
described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

         10. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers, and
the several Underwriters set forth



 
                                       23
   24
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement shall remain in full force and effect, regardless of (i) any
investigation made by or on behalf of the Company, any of its officers or
directors, any Underwriter or any controlling person referred to in Section 8
hereof and (ii) delivery of and payment for the Securities. The respective
agreements, covenants, indemnities and other statements set forth in Sections 6
and 8 hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement.

         11.      Termination.

                  (a) This Agreement may be terminated with respect to the Firm
         Securities or any Option Securities in the sole discretion of the
         Representatives by notice to the Company and (in the case of a
         termination with respect to the Firm Securities) the Attorney-in-Fact
         given prior to the Firm Closing Date or the related Option Closing
         Date, respectively, in the event that the Company shall have failed,
         refused or been unable to perform all obligations and satisfy all
         conditions on their part to be performed or satisfied hereunder at or
         prior thereto or, if at or prior to the Firm Closing Date or such
         Option Closing Date, respectively,

                           (i) the Company or any of its subsidiaries shall have
                  sustained any material loss or interference with their
                  respective businesses or properties from fire, flood,
                  hurricane, accident or other calamity, whether or not covered
                  by insurance, or from any labor dispute or any legal or
                  governmental proceeding or there shall have been any material
                  adverse change, or any development involving a prospective
                  material adverse change (including without limitation a change
                  in control of the Company), in the condition (financial or
                  otherwise), business prospects, net worth or results of
                  operations of the Company and its subsidiaries, taken as a
                  whole, except in each case as described in or contemplated by
                  the Prospectus (exclusive of any amendment or supplement
                  thereto after the date hereof), which, in the sole judgment of
                  the Representatives, makes it impractical to offer or deliver
                  the Firm Securities or the Option Securities, as applicable,
                  on the terms contemplated by the Prospectus;

                           (ii) trading in the Common Stock shall have been
                  suspended by the Commission or the NYSE;

                           (iii) trading in securities generally on the NYSE
                  shall have been suspended or minimum or maximum prices shall
                  have been established on such exchange or market system;

                           (iv) a banking moratorium shall have been declared by
                  New York or United States authorities; or

                           (v) there shall have been (A) an outbreak or
                  escalation of hostilities between the United States and any
                  foreign country, (B) an outbreak or escalation of any other
                  insurrection or armed conflict involving the United States or
                  (C) any other calamity or crisis having an effect on the
                  financial markets that, in any case referred to in this clause
                  (v), in the sole judgment of the Representatives, makes it
                  impracticable or inadvisable to proceed with the public
                  offering or the delivery of the



 
                                       24
   25
                  Securities as contemplated by the Registration Statement, as
                  amended as of the date hereof.

                  (b) Termination of this Agreement pursuant to this Section 11
         shall be without liability of any party to any other party except as
         provided in Section 10 hereof.

         12. Information Supplied by Underwriters. The statements set forth in
the last paragraph on the front cover page and under the heading "Underwriting'
in any Preliminary Prospectus or the Prospectus (to the extent such statements
relate to the Underwriters) constitute the only information furnished by any
Underwriter through the Representatives to the Company for the purposes of
Sections 2(b), 8(a), and 8(b) hereof. The Underwriters confirm that such
statements (to such extent) are correct.

         13. Notices. All communications hereunder shall be in writing and, if
sent to any of the Underwriters, shall be mailed or delivered or telegraphed and
confirmed in writing to H.D. Brous & Co., Inc., 2700 No. Central Avenue, Suite
1250, Phoenix, Arizona 85004, Attention: Scott Miller, Syndicate Department; and
if sent to the Company, shall be mailed, delivered or telegraphed and confirmed
in writing to the Company at 2700 No. Central Avenue, Suite 1000, Phoenix,
Arizona 85004, Attention: Donald W. Townsend, President.

         14. Successors. This Agreement shall inure to the benefit of and shall
be binding upon the several Underwriters, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or
any provisions herein contained, this Agreement and all conditions and
provisions hereof being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person except that (i)
the indemnities of the Company contained in Section 8 of this Agreement shall
also be for the benefit of any person or persons who control any Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
and (ii) the indemnities of the Underwriters contained in Section 8 of this
Agreement shall also be for the benefit of the directors of the Company, the
officers of the Company who have signed the Registration Statement, and any
person or persons who control the Company within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act. No purchaser of Securities from any
Underwriter shall be deemed a successor because of such purchase.

         15. APPLICABLE LAW. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT,
AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT
TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS.

         16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.
