of  the  mutual   covenants   herein  contained  and  other  good  and  valuable
consideration,  the receipt  and  sufficiency  of which is hereby  acknowledged,
hereby confirm and agree as follows:

SECTION 1. RECITALS.

         1.1 Borrower and the Administrative Agent, NBD Bank as Co-Agent and the
Banks named therein  entered into that Credit  Agreement  dated October 31, 1996
(the "Credit Agreement") to provide financial  accommodations to the Borrower as

         1.2  Borrower  and the  Administrative  Agent,  with the consent of the
Banks, desire to modify the Credit Agreement as set forth herein.

         1.3 All undefined  capitalized terms used herein shall have the meaning
given them in the Credit Agreement.

SECTION 2. CREDIT AGREEMENT.

         2.1 The following  definition  in Section 1.1 of the Loan  Agreement is
hereby amended to read as follows:

                  "Consolidated  Debt" shall mean the total Debt of the Borrower
         and  its  Subsidiaries,   less  the  outstanding  principal  amount  of
         Convertible Subordinated  Indebtedness,  all computed on a consolidated
         basis in accordance with GAAP.

         2.2 The following definition is hereby added to Section 1.1 of the Loan
         Agreement:

                  "Convertible    Subordinated    Indebtedness"    shall    mean
         Subordinated  Indebtedness  that  is  convertible  into  equity  of the
         Borrower,  which  amount for purposes of the  calculation  of the ratio
         under Section 6.8 shall not exceed at any time $100,000,000.00.

SECTION 3. OTHER MODIFICATIONS, RATIFICATIONS AND AGREEMENTS.

         3.1 All references to the Credit  Agreement in the other Loan Documents
are hereby amended to refer to the Credit Agreement as hereby amended.

         3.2 Borrower  hereby  reaffirms to Lender each of the  representations,
warranties,  covenants  and  agreements  of  Borrower  set  forth in the  Credit
Agreement,  with the same  force and  effect as if each were  separately  stated
herein and made as of the date hereof.

         3.3 Borrower hereby ratifies, reaffirms,  acknowledges, and agrees that
the Notes and the Credit Agreement represent valid,  enforceable and collectible
obligations  of  Borrower,  and that  there are no  existing  claims,  defenses,
personal or  otherwise,  or rights of setoff  whatsoever  with respect to any of
these documents or instruments.  In addition,  Borrower hereby expressly waives,
releases and absolutely  and forever  discharges the Banks and their present and
former  shareholders,  directors,  officers,  employees  and  agents,  and their
separate and respective heirs, personal representatives, successors and assigns,
from any and all liabilities,  claims,  demands,  damages,  action and causes of
action,  whether  known or unknown  and  whether  contingent  or  matured,  that
Borrower  may now  have,  or has had  prior  to the  date  hereof,  or that  may
hereafter arise with respect to acts, omissions or events occurring prior to the
date hereof and, without limiting the generality of the foregoing,  from any and
all liabilities,  claims, demands,  damages, actions and causes of action, known
or unknown, contingent or matured, arising out of, or in any way connected with,
the  Loans.  Borrower  further  acknowledges  and  represents  that no event has
occurred and no condition  exists that,  after notice or lapse of time, or both,
would  constitute  a default  under  this  Agreement,  the  Notes or the  Credit
Agreement.

         3.4 All terms,  conditions and  provisions of the Credit  Agreement are
continued in full force and effect and shall  remain  unaffected  and  unchanged
except as specifically amended hereby. The Credit Agreement,  as amended hereby,
is hereby  ratified  and  reaffirmed  by  Borrower,  and  Borrower  specifically
acknowledges the validity and enforceability thereof.

SECTION 4. GENERAL.

         4.1 This  Agreement  in no way acts as a release or  relinquishment  of
those rights  securing  payment of the Loans.  Such rights are hereby  ratified,
confirmed, renewed and extended by Borrower in all respects.

         4.2 The  modifications  contained  herein shall not be binding upon the
Banks until the Administrative Agent shall have received all of the following:

                  (a) An  original  of  this  Agreement  fully  executed  by the
         Borrower.

                  (b)  Such  resolutions  or   authorizations   and  such  other
         documents  as the  Administrative  Agent may  require  relating  to the
         existence  and good  standing of the Borrower and the  authority of any
         person  executing  this  Agreement or other  documents on behalf of the
         Borrower.

         4.3 Borrower shall execute and deliver such additional documents and do
such  other acts as the Banks may  reasonably  require  to fully  implement  the
intent of this Agreement.
                                      -2-

         4.4  Borrower  shall  pay all costs and  expenses,  including,  but not
limited to, reasonable  attorneys' fees incurred by the Administrative  Agent in
connection herewith, whether or not all of the conditions described in Paragraph
4.2 above are satisfied.  Banks, at their option,  but without any obligation to
do so,  may  advance  funds  to pay any such  costs  and  expenses  that are the
obligation of the Borrower,  and all such funds  advanced shall bear interest at
the highest rate provided in the Notes and shall be due and payable upon demand.


         4.5 Notwithstanding anything to the contrary contained herein or in any
other instrument executed by Borrower, the Administrative Agent or the Banks, or
in any other action or conduct undertaken by Borrower,  the Administrative Agent
or the  Banks on or  before  the date  hereof,  the  agreements,  covenants  and
provisions  contained  herein shall  constitute  the only evidence of the Banks'
consent to modify the terms and provisions of the Credit Agreement. Accordingly,
no express or implied consent to any further modifications  involving any of the
matters set forth in this Agreement or otherwise shall be inferred or implied by
the  Banks'  consent to this  Agreement.  Further,  the  Banks'  consent to this
Agreement  shall not  constitute  a waiver  (either  express or  implied) of the
requirement that any further  modification of the Credit Agreement shall require
the express  written  consent of the Banks;  no such consent  (either express or
implied) has been given as of the date hereof.

         4.6 Time is hereby  declared to be of the essence  hereof of the Credit
Agreement, and Banks require, and Borrower agrees to, strict performance of each
and every covenant,  condition,  provision and agreement  hereof,  of the Credit
Agreement.

         4.7 This  Agreement  shall be  binding  upon,  and  shall  inure to the
benefit  of, the  parties  hereto  and their  heirs,  personal  representatives,
successors and assigns.
                                       -3-

         4.8 This  Agreement is made for the sole  protection and benefit of the
parties  hereto,  and no other  person or entity  shall have any right of action
hereon.


         4.9 This Agreement shall be governed by and construed  according to the
laws of the State of Arizona.

         IN  WITNESS  WHEREOF,  these  presents  are  executed  as of  the  date
indicated above.
