          (b)  either:

          (a)  For all services rendered by the Employee in any capacity
during the term of this Agreement following a Change of Control, including
services as an executive, officer, director, or member of any committee of
the Company or any subsidiary or affiliate thereof, the Company shall pay
the Employee a fixed salary at a rate of not less than Employee's salary in
effect at the time of the Change in Control, subject to such periodic
increases as the Board of Directors, or a committee designated by said
Board, shall deem appropriate in accordance with the Company's customary
procedures and practices regarding the salaries of senior management
employees.  Such salary shall be payable in accordance with the customary
payroll practices of the Company.  Such periodic increases in salary, once
granted, shall not be subject to revocation.

          (b)  Nothing in this Agreement shall preclude or affect any
rights or benefits that may now or hereafter be provided for the Employee
or for which the Employee may be or become eligible under any bonus or
other form of compensation or employee benefit plan now existing or that

Employee shall:

               (i)    participate in the Company's Retirement Plan and any
related excess benefit or supplemental retirement program (hereinafter

which senior management employees are eligible; provided, however, that
nothing in this Agreement shall preclude the Company from amending or
terminating any such plan or program, on the condition that such amendment
or termination is applicable to all of the Company's senior management
employees generally.

     1.5  BUSINESS EXPENSES.  The Company shall pay or reimburse the
Employee for all reasonable travel or other expenses incurred in connection
with the performance of the Employee's duties under this Agreement in
accordance with such procedures as the Company may from time to time

Employee's eligibility to participate in all group health, dental,
hospitalization, life, travel or accident or other insurance plans or
programs and all other perquisites, fringe benefit or retirement plans or
additional compensation, including termination pay programs, which the
Company may hereafter, in its sole and absolute discretion, elect to make
available to its senior management employees generally, and the Employee
shall be eligible to receive, during his employment, all benefits and
emoluments for which key employees are eligible under every such plan,
program, perquisite or arrangement to the extent permissible under the
general terms and provisions thereof.
     1.7  TERMINATION OF EMPLOYMENT.  Notwithstanding any other provision
of this Agreement, the Employee's employment with the Company may be
terminated:

          (a)  by the Company:

               (i)    in the event of the Employee's fraud or dishonesty
which has resulted or is likely to result in material economic damage to
the Company or any of its subsidiaries, as determined by a vote of two-
thirds (2/3) of the Directors of the Company at a meeting of the Board of
Directors at which the Employee had an opportunity to be heard and such
termination is based on facts and circumstances known by a majority of the
non-employee Directors for a period of no more than twelve (12) months by
written notice to the Employee, specifying the event relied upon for such
termination; or

               (ii)   upon the Disability or death of the Employee. For
purposes of this Agreement, the term "Disability" is defined as the
inability of the Employee to engage in his regular occupation for twelve
(12) consecutive months and the inability thereafter to engage in any
occupation in which the Employee could reasonably expect to engage giving
due consideration to the Employee's education, training and experience. The
Employee must be under the regular medical care of a physician in
connection with treatment for such Disability.

          (b)  by the Employee:

               (i)    if, following a Change of Control, there has been any
material change by the Company of the Employee's status, title, authority,
duties or responsibilities which change would cause the Employee's position
with the Company to become of less responsibility or scope from that which
the Employee held immediately prior to the Change in Control;

               (ii)   upon the assignment or reassignment by the Company or
by one of its subsidiaries of the Employee to another place of employment
more than fifty (50) miles from the Employee's current place of employment;

               (iii)  upon the liquidation, dissolution, consolidation or
merger of the Company, or transfer of all or substantially all of its
assets, other than a transaction in which a successor corporation with a
net worth at least equal to that of the Company assumes this Agreement and
all obligations and undertakings of the Company hereunder; or

               (iv)   upon a reduction in the Employee's target
compensation or any component thereof, following a Change of Control,
except as part of a salary reduction program affecting the Company's
management employees generally, or other material breach of this Agreement
by the Company or any of its subsidiaries, by written notice to the
Company, specifying the event or events relied upon for such termination
and given at any time within one (1) year after the occurrence of such
event or events. For the purpose of this Agreement, "target compensation"
shall include the Employee's base salary plus the opportunity to
participate in the Company's annual incentive plan and the Company's 1994
Omnibus Stock and Incentive Plan or any successor plans thereto (the
"Plan"), at the same level and terms available to the Employee immediately
prior to the Change in Control; or

          (c)by either the Company or the Employee, if the Employee accepts
employment or a consulting position with another company.

                                ----------
                      Compensation Upon Termination
                      -----------------------------

     2.1  BASIC SEVERANCE PAYMENT.  In the event of a Qualifying
Termination, the Company shall, as liquidated damages or severance pay, or
both, pay to the Employee and provide the Employee and the dependents,
beneficiaries and estate of the Employee within thirty (30) business days
after such Qualifying Termination of employment with the following:

          (a)  A lump sum cash amount equal to:

               (i)    three (3) times the sum of Employee's base annual
salary immediately preceding the Change in Control; adjusted to reflect any
increases in such base salary following the Change in Control plus the
Employee's annual target bonus; and

               (ii)   a prorated annual target bonus for the short year in
which the Qualifying Termination occurs.

          (b)  A lump sum cash amount equal to the present value of the
excess of:

               (i)    the aggregate benefit that would have been paid under
the Retirement Program described in paragraph 1.4(b)(i) above as in effect
on the date first above written, if the Employee had continued to be
employed and to be entitled to service credit for eligibility and benefit
purposes during the sixty (60) month period immediately following such
Qualifying Termination, at an annual rate of compensation equal to that
used to calculate the payments provided by paragraph 2.1(a) above,
calculated on the basis of the compensation amount used in the benefit
formula under said Retirement Program, and assuming that the Employee is
fully vested in such benefit, over

               (ii)   the aggregate benefit actually payable under the
Retirement Program and any successor retirement program of the Company
consisting of a tax-qualified pension plan and a related excess benefit
plan. In clarification of the immediately preceding sentence, the aggregate
benefit that would have been paid under the Retirement Program shall be
calculated as of the normal or early retirement date for which the Employee
would have qualified, if the Employee were still employed on that date, and
which would produce the highest present value.

          (c)  To the extent not otherwise paid or payable under this
Agreement or the Plan, the present value of any Employee awards under the
Plan which are outstanding at the time of the Qualifying Termination
(whether vested or not) prorated based on length of service, and assuming,
for the purpose of this paragraph, that any contingencies or performance
goals related to such awards are fully achieved at the one hundred percent
(100%) level.

          (d)  For purposes of calculating the lump sum cash payments
provided by paragraph 2.1(b) above, present value shall be determined by
using a discount factor equal to one (1) percentage point below the Prime
Rate, compounded annually.  The "Prime Rate" shall be the base rate on
corporate loans at large U.S. money center commercial banks as reported in
the Wall Street Journal (or, if such rate is no longer published, such
other base rate on corporate loans by large money center commercial banks
in the United States to their most credit worthy customers as published by
any newspaper or periodical of general circulation) as of the date on which
Qualifying Termination shall have occurred.

          (e)  For a period of sixty (60) months (commencing with the month
in which the Qualifying Termination shall have occurred), the Employee
shall continue to be entitled to all employee benefits provided for in
paragraph 1.4(b)(v) through (vii) above as if the Employee were still
employed during such period under this Agreement, with benefits based upon
the compensation used to calculate the payments provided by paragraph
2.1(a) above, and if and to the extent that such benefits shall not be
payable or provided under any such plan, the Company shall pay or provide
such benefits on an individual basis. The benefits provided for in
paragraph 1.4(b)(vii) above in accordance with this paragraph 2.1(e) shall
be secondary to any comparable benefits provided by another employer.

     2.2  TAX WITHHOLDING.  The Company may withhold from any payment made
under this Agreement, all federal, state or other tax as required by law,
government regulation or ruling.

     2.3  EXCISE TAX GROSS-UP.  Should Employee become entitled to any
payment or benefit under this Agreement (the "Total Payments"), and the
Total Payments are subject to the tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended (the "Excise Tax"), the Company
shall pay to Employee, in cash, an additional amount (the "Gross-Up
Payment") such that the net amount retained by the Employee after deduction
of

          (a)  any Excise Tax upon the Total Payments, and

          (b)  any federal, state or local income tax and Excise Tax upon
the Gross-Up Payment provided for by this paragraph,
shall be equal to the Total Payments. Such payment shall be made to
Employee within thirty (30) days from the Qualifying Termination giving
rise to payments under this Agreement.

     2.4  TAX COMPUTATION.  For purposes of determining whether any of the
Total Payments will be subject to the Excise Tax and the amounts of such
Excise Tax:

          (a)  Any payments or benefits received by Employee in connection
with a Qualifying Termination (whether pursuant to the terms of this
Agreement or any other plan, or agreement with the Company, or with any
person (as defined in Section 3(a)(9) of the Exchange Act, including a
"group" as defined in Section13(d) therein) whose actions result in a
Change in Control or any person affiliated with the Company or such
persons) shall be treated as "parachute payments" within the meaning of
Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended (the
"Code"), and all "excess parachute payments" within the meaning of Section
280G(b)(1) shall be treated as subject to the Excise Tax, unless in the
opinion of tax counsel as supported by the Company's independent auditors
and acceptable to the Employee, such other payments or benefits (in whole
or in part) do not constitute parachute payments, or unless such excess
parachute payments (in whole or in part) represent reasonable compensation
for services actually rendered within the meaning of Section 280G(b)(4) of
the Code in excess of the base amount within the meaning of Section
280G(b)(3) of the Code, or are otherwise not subject to the Excise Tax;

          (b)  The amount of the Total Payments which shall be treated as
subject to the Excise Tax shall be equal to the lesser of:

               (i)    the total amount of the Total Payments; or

               (ii)   the amount of excess parachute payments within the
meaning of Section 280G(b)(1) (after applying clause (a) above); and

               (iii)  the value of any noncash benefits or any deferred
payment or benefit shall be determined by the Company's independent
auditors in accordance with the principles of Sections 280G(d)(3) and (4)
of the Code.

     For purposes of determining the amount of the Gross-Up Payment, the
Employee shall be deemed to pay federal income taxes at the highest
marginal rate of federal income taxation in the calendar year in which the
Gross-Up Payment is to be made, and state and local income taxes at the
highest marginal rate of taxation in the state and locality of the
Employee's residence on the date of Qualifying Termination, net of the
maximum reduction in federal income taxes which could be obtained from
deduction of such state and local taxes.

     2.5  SUBSEQUENT RECALCULATION.  In the event the Internal Revenue
Service adjusts the computation made by the Company under paragraph 2.4
herein so that Employee did not receive the greatest net benefit, the
Company shall reimburse Employee for the full amount necessary to make
Employee whole, plus a market rate of interest, as determined by the
Company.

     2.6  SOURCE OF PAYMENTS.  All payments provided for in paragraphs 1.4,
2.1, 2.3, and 2.5 above shall be paid in cash from the general funds of the
Company.  The Company shall not be required to establish a special or
separate fund or other segregation of assets to assure such payments.


                               ARTICLE III
                               -----------
                              Miscellaneous
                              -------------

     3.1  LITIGATION EXPENSES.  In the event of any litigation or other
proceeding between the Company and the Employee with respect to the subject
matter of this Agreement and the enforcement of rights hereunder, the
Company shall advance the Employee all reasonable costs and expenses
relating to such litigation or other proceeding as they are incurred,
including reasonable attorneys' fees and expenses, however, if such
litigation results in any settlement or judgment or order in favor of the
Employer, Employee shall reimburse Employer for all such monies advanced.

     Notwithstanding the preceding sentence or any provision of Arizona law
to the contrary, in no event shall the Employee be required to reimburse
the Company for any of the costs and expenses incurred by the Company on
its own behalf relating to such litigation or other proceeding.  The
obligation of the Company under this paragraph 3.1 shall survive the
termination of this Agreement (whether such termination is by the Company,
by the Employee, upon the expiration of this Agreement or otherwise).

     3.2  ARBITRATION.  Any controversy or claim arising out of or relating
to this Agreement or the breach thereof, shall be settled by arbitration.
The Party desiring arbitration shall deliver written notice of demand for
arbitration to the other Party within a reasonable time after the
controversy or claim arises, but in no event after the date when
institution of legal or equitable proceedings based on such controversy or
claim would be barred by the applicable statute of limitations.

     The arbitration shall be heard before a single neutral arbitrator
appointed by mutual agreement of the Parties.  If the Parties fail to agree
upon a single arbitrator within ten (10) days of the referral of the
dispute to arbitration, each Party shall choose one arbitrator who shall
sit on a three-member arbitration panel.  The two arbitrators so chosen
shall within ten (10) days select a third arbitrator.  In either case, the
arbitrator(s) shall be knowledgeable in executive and employee compensation
matters, and shall not have any current or past substantial business or
financial relationships with any Party to the arbitration.  The arbitration
shall be conducted under the rules of the American Arbitration Association,
except as modified herein, and shall take place in Tucson, Arizona.  No
discovery shall be permitted.  The arbitrator shall issue a scheduling
order that shall not be modified except by the mutual agreement of the
Parties.

     The award of the arbitrator(s) shall be final and binding and shall be
enforceable in any court of competent jurisdiction.

     3.3  ENTIRE UNDERSTANDING.  This Agreement contains the entire
understanding between the Company and the Employee with respect to the
subject matter hereof and supersedes any prior employment agreement and
amendment thereto between the Company and the Employee, except that this
Agreement shall not affect or operate to reduce any benefit or compensation
inuring to the Employee of a kind elsewhere provided and not expressly
provided in this Agreement.

     3.4  SEVERABILITY.  If, for any reason, any one or more of the
provisions or part of a provision contained in this Agreement shall be held
to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provision or part
of a provision of this Agreement not held so invalid, illegal or
unenforceable, and each other provision or part of a provision shall, to
the full extent consistent with law, continue in full force and effect.  If
this Agreement is held invalid or cannot be enforced, then to the full
extent permitted by law, any prior agreement between the Company and the
Employee shall be deemed reinstated as if this Agreement had not been
executed.

     3.5.  CONSOLIDATION, MERGER, OR SALE OF ASSETS.  Nothing in this
Agreement shall preclude the Company from consolidating or merging into or
with or transferring all or substantially all of its assets to another
corporation with a net worth at least equal to that of the Company and
which assumes this Agreement and all obligations and undertakings of the
Company hereunder.  Upon such a consolidation, merger or transfer of assets
and assumption, the term, "the Company", as used herein shall mean such
other corporation and this Agreement shall continue in full force and
effect.
