         NOW, THEREFORE, for valuable consideration, the receipt and sufficiency

                                   THE CREDITS

          SECTION 1.1.      LINE OF CREDIT.

         (a) Line of Credit. Subject to the terms and conditions of this
Agreement, Bank hereby agrees to make advances to Borrower from time to time up
to and including June 1, 1999, not to exceed at any time the aggregate principal
amount of Twenty Million Dollars ($20,000,000.00) ("Line of Credit"), the
proceeds of which shall be used to finance Borrower's working capital
requirements. Borrower's obligation to repay advances under the Line of Credit
shall be evidenced by a promissory note substantially in the form of Exhibit A
attached hereto ("Line of Credit Note"), all terms of which are incorporated
herein by this reference.

         (b) Letter of Credit Subfeature. As a subfeature under the Line of
Credit, Bank agrees from time to time during the term thereof to issue standby
and/or sight commercial letters of credit for the account of Borrower (each, a

that the form and substance of each Letter of Credit shall be subject to
approval by Bank, in its sole discretion; and provided further, that the
aggregate undrawn amount of all outstanding Letters of Credit shall not at any
time exceed Two Million Dollars ($2,000,000.00). No Letter of Credit shall have
an expiration date subsequent to the maturity date of the Line of Credit. The

Credit and shall not be available for borrowings thereunder. Each Letter of
Credit shall be subject to

the additional terms and conditions of the Letter of Credit Agreement and
related documents, if any, required by Bank in connection with the issuance
thereof (each, a "Letter of Credit Agreement" and collectively, "Letter of
Credit Agreements"). Each draft paid by Bank under a Letter of Credit shall be
deemed an advance under the Line of Credit and shall be repaid by Borrower in
accordance with the terms and conditions of this Agreement applicable to such
advances; provided however, that if advances under the Line of Credit are not
available, for any reason, at the time any draft is paid by Bank, then Borrower
shall immediately pay to Bank the full amount of such draft, together with
interest thereon from the date such amount is paid by Bank to the date such
amount is fully repaid by Borrower, at the rate of interest applicable to
advances under the Line of Credit. In such event Borrower agrees that Bank, in
its sole discretion, may debit any demand deposit account maintained by Borrower
with Bank for the amount of any such draft.

         (c) Borrowing and Repayment. Borrower may from time to time during the
term of the Line of Credit borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions contained herein or in the Line of Credit Note; provided however,
that the total outstanding borrowings under the Line of Credit shall not at any
time exceed the maximum principal amount available thereunder, as set forth
above.

occurrence and continuation of an Event of Default, the recipient has accepted

         SECTION 7.11.  ARBITRATION.

         (a) Arbitration. Upon the demand of any party, any Dispute shall be
resolved by binding arbitration (except as set forth in (e) below) in accordance
with the terms of this Agreement. A "Dispute" shall mean any action, dispute,
claim or controversy of any kind, whether in contract or tort, statutory or
common law, legal or equitable, now existing or hereafter arising under or in
connection with, or in any way pertaining to, any of the Loan


                                      -18-
<PAGE>   19
Documents, or any past, present or future extensions of credit and other
activities, transactions or obligations of any kind related directly or
indirectly to any of the Loan Documents, including without limitation, any of
the foregoing arising in connection with the exercise of any self-help,
ancillary or other remedies pursuant to any of the Loan Documents. Any party may
by summary proceedings bring an action in court to compel arbitration of a
Dispute. Any party who fails or refuses to submit to arbitration following a
lawful demand by any other party shall bear all costs and expenses incurred by
such other party in compelling arbitration of any Dispute.

         (b) Governing Rules. Arbitration proceedings shall be administered by
the American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules. All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the Loan
Documents. The arbitration shall be conducted at a location in Arizona selected
by the AAA or other administrator. If there is any inconsistency between the
terms hereof and any such rules, the terms and procedures set forth herein shall
control. All statutes of limitation applicable to any Dispute shall apply to any
arbitration proceeding. All discovery activities shall be expressly limited to
matters directly relevant to the Dispute being arbitrated. Judgment upon any
award rendered in an arbitration may be entered in any court having
jurisdiction; provided however, that nothing contained herein shall be deemed to
be a waiver by any party that is a bank of the protections afforded to it under
12 U.S.C. Section 91 or any similar applicable state law.

         (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration hereunder.

         (d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be
active members of the Arizona State Bar or retired judges of the state or
federal judiciary of Arizona with expertise in the substantive law applicable to
the subject matter of the Dispute. Arbitrators are empowered to resolve Disputes
by


                                      -19-
<PAGE>   20
summary rulings in response to motions filed prior to the final arbitration
hearing. Arbitrators (i) shall resolve all Disputes in accordance with the
substantive law of the state of Arizona, (ii) may grant any remedy or relief
that a court of the state of Arizona could order or grant within the scope
hereof and such ancillary relief as is necessary to make effective any award,
and (iii) shall have the power to award recovery of all costs and fees, to
impose sanctions and to take such other actions as they deem necessary to the
same extent a judge could pursuant to the Federal Rules of Civil Procedure, the
Arizona Rules of Civil Procedure or other applicable law. Any Dispute in which
the amount in controversy is $5,000,000 or less shall be decided by a single
arbitrator who shall not render an award of greater than $5,000,000 (including
damages, costs, fees and expenses). By submission to a single arbitrator, each
party expressly waives any right or claim to recover more than $5,000,000. Any
Dispute in which the amount in controversy exceeds $5,000,000 shall be decided
by majority vote of a panel of three arbitrators; provided however, that all
three arbitrators must actively participate in all hearings and deliberations.

         (e) Judicial Review. Notwithstanding anything herein to the contrary,
in any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law. In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
Arizona, and (iii) the parties shall have in addition to the grounds referred to
in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
Arizona. Judgment confirming an award in such a proceeding may be entered only
if a court determines the award is supported by substantial evidence and not
based on legal error under the substantive law of the state of Arizona.

         (f) Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent


                                      -20-
<PAGE>   21
necessary to exercise any judicial review rights set forth herein. If more than
one agreement for arbitration by or between the parties potentially applies to a
Dispute, the arbitration provision most directly related to the Loan Documents
or the subject matter of the Dispute shall control. This arbitration provision
shall survive termination, amendment or expiration of any of the Loan Documents
or any relationship between the parties.


         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first written above.
