         purposes or for the short-term working capital needs of Borrower; and
         (iv) (A) immediately upon disbursement of the Advance, the aggregate
         unpaid principal balance of the Facility Note does not exceed the
         Facility Commitment, (B) the amount of the Advance does not exceed the
         then effective Net


                                       17
<PAGE>   18
         Availability, and (C) such Advance would not cause a violation of any
         of the financial covenants set forth in SECTION 9.7.

                  (b) Reborrowings. Subject to the terms and conditions hereof,
         Borrower may borrow, prepay and reborrow under SECTION 2.1(a) so long
         as (a) the principal balance of the Facility Note at any time
         outstanding does not exceed the Facility Commitment and (B) the amount
         of an advance does not exceed the then effective Net Availability.
         Lender, at its option, from time to time may make advances to or on
         behalf of Borrower in excess of the above stated limitations without
         impairing Lender's right to demand, at any time, repayment of such
         excess upon ten (10) days' written demand from Lender. Borrower's
         obligation to repay each advance made pursuant to this Section and to
         pay interest thereon, shall be evidenced by the Facility Note and this
         Agreement.

                  (c) Maturity. The Facility shall become fully due and payable
         and no addition Advances shall be available on or after the Restated
         Maturity Date.

                  (d) Principal and Interest Payments. Borrower shall pay to
         Lender (in arrears) accrued but unpaid interest, computed at the
         Facility Rate, on all sums outstanding under the Facility on the fifth
         day of each calendar month following the Restated Closing Date and
         thereafter until the Restated Maturity Date, at which time Borrower
         shall pay to Lender the amount necessary to pay in full all remaining
         principal and interest, together with any Lender's Expenses due Lender.

                  (e) Unused Commitment Fee. From and after the Restated Closing
         Date, Borrower shall pay Lender an unused commitment fee for the
         immediately preceding Fiscal Quarter, in an amount equal to one-half of
         one percent (0.50%) per annum multiplied by an amount equal to the
         difference between the Facility Commitment and the average daily
         balance of the Facility during the immediately preceding Fiscal
         Quarter. Such fee shall be calculated on the basis of a 360-day year
         for the actual number of days elapsed and be payable in arrears,
         beginning on the fifteenth (15th) day of the First Fiscal Quarter
         following the Restated Closing Date, on the fifteenth (15th) day of
         each Fiscal Quarter thereafter, and on the Restated Maturity Date;
         provided that, if the Commitment is at any time terminated in its
         entirety, all accrued commitment fees relating thereto shall be payable
         at the applicable rate on the effective date of such termination.

SECTION 3 -- GENERAL ADVANCE AND REPAYMENT PROCEDURES

         3.1 Advances Evidenced and Secured By Restated Loan Documents. All
Advances made by Lender pursuant to this Agreement and all other Obligations,
whether arising from Advances made by Lender under this Agreement, reasonable
costs incurred by Lender for purposes of preserving or protecting the Collateral
pursuant to any of the Restated Security Documents, reasonable costs incurred by
Lender in collecting any portion of the Obligations or in enforcing any of its
rights under any of the Restated Loan Documents or any other amounts that
Borrower are obligated to pay to Lender pursuant to the Restated Loan Documents,
shall be evidenced by the Facility Note, and secured by the Liens of the
Restated Security Documents.


                                       18
<PAGE>   19
         3.2 Requests for Advances. Subject to the provisions of SECTIONS 2 AND
4, Lender shall make Advances under the Facility upon receipt of appropriate
requests therefor signed by one of the Authorized Signators in a form reasonably
satisfactory to Lender, together with such information and writings as this
Agreement may require to obtain such Advances under the Restated Loan. Borrower
shall make its requests for Advances not later than 10:00 a.m. on the date an
Advance is required to be disbursed. All requests for Advances shall: (a)
contain the appropriate information required by SECTION 2 hereof; and (b)
clearly identify any amounts requested for payment of the Restated Loan.

         3.3 Withholding from Advances. Upon the occurrence of an Event of
Default, Lender is expressly authorized to withhold from any Advance under this
Agreement, or portion thereof, as Lender in its discretion considers necessary
to protect Lender from loss on account of any obligation required by this
Agreement to have been performed by Borrower that has not been performed.

         3.4 Protective Advances. Although Lender shall have no obligation to
make any Advance under this Agreement unless and until all of the relevant
conditions set forth herein have been fulfilled, Lender, in its sole discretion,
may make such Advance prior to that time without waiving or releasing any of the
requirements or conditions of this Agreement; but Borrower shall continue to be
strictly obligated and subject thereto, and all such conditions shall
nevertheless be strictly and punctually fulfilled; and, notwithstanding any such
disbursement, Lender, at its discretion, may discontinue any further Advances at
any time until all of the relevant conditions of this Agreement have been
strictly fulfilled. In the event of any dispute that, in the good faith opinion
of Lender, may endanger the fulfillment of any condition or covenant contained
herein, Lender may agree to make Advances for the account of Borrower without
prejudice to Borrower's rights, if any, to recover said funds from the party to
whom paid. All sums paid or agreed to be paid pursuant to such agreement shall
be for the account of Borrower, and shall constitute Advances pursuant to
SECTION 2.1. At any time that an uncured or non-waived Event of Default exists,
Lender may at its sole option make Advances from the Restated Loan in payment of
taxes, assessments, liens or encumbrances existing against any of the
Collateral, and any charges and expenses that are the obligation of Borrower
under any of the Restated Loan Documents. Notwithstanding what may otherwise be
provided herein, Lender shall not make Advances in payment of taxes,
assessments, liens or encumbrances if Borrower is then contesting such liability
and Borrower has provided a bond or other form of additional collateral security
acceptable to Lender (in its sole and absolute discretion) which when liquidated
would provide enough cash to satisfy all obligations of Borrower under such
liability including, without limitation, interest, penalties, costs and fees.
All Advances pursuant to this SECTION 3.4 shall be deemed made under and added
to the outstanding balance of Facility Note and bear interest as provided
thereunder.

         3.5 Telephonic Notice of Advance Request. If Borrower elects to give
telephonic notice to Lender of its advance request, then Borrower shall promptly
mail written confirmation thereof to Lender, which confirmation shall be signed
by one of the Authorized Signators. In implementing this arrangement under this
SECTION 3.5, Lender is authorized to act upon and honor any such telephonic
notice which Lender believes, in its sole discretion, to emanate from an
Authorized Signator acting pursuant to this Agreement, whether in fact that be
the case or not, and


                                       19
<PAGE>   20
Lender shall not be liable for acting in good faith on notices which emanate
from unauthorized individuals.

         3.6 Disbursement of the Restated Loan. Lender, at its option, may waive
any condition to disbursement of any Advance or any disbursement procedure set
forth in SECTION 4 hereof, but no such waiver shall be deemed to constitute a
waiver of any other condition or procedure. Lender shall disburse the amounts
requested by direct deposit into Borrower's account with Lender or as otherwise
directed by Borrower.

         3.7 Statements. Lender shall send to Borrower monthly interest
billings or statements by regular first class United States mail setting forth
the accrued and unpaid balances of principal and interest due on the Restated
Loan, and Borrower agrees to advise Lender with reasonable promptness if
Borrower is aware of any errors therein.

         3.8 Time and Place of Payments. All payments of the Obligations
(including without limitation payments of interest thereon), shall be made not
later than 5:00 p.m. Phoenix, Arizona Time at the primary office of Lender in
Phoenix, Arizona 85004. Funds received after such hour on any Business Day shall
be treated for all purposes of this Agreement as having been received on the
next succeeding Business Day. Whenever any payment to be made pursuant to the
Restated Loan Documents is due on a Saturday, Sunday or any other day which is
not a Business Day, such payment may be made on the next succeeding Business
Day, and such extension of time shall in such case be included in computing
interest in connection with such payments. Borrower authorizes Lender to
collect all interest, fees, costs, and/or expenses due under this Agreement by
charging Borrower's demand deposit account number 97003297 with Lender, or any
other demand deposit account maintained by Borrower with Lender, for the full
amount thereof. Should there be insufficient funds in any such demand deposit
account to pay all such sums when due, the full amount of such deficiency shall
be immediately due and payable by Borrower.

         3.9 Prepayment. Borrower may at any time, and from time to time, repay
the Obligations in whole or in part without penalty, provided that all accrued
and unpaid interest on the Obligations to be prepaid is also paid. All such
prepayments shall be applied in the inverse order of maturity. All prepayments
made by Borrower to Lender, shall be in lawful money of the United States of
America in federal or other funds immediately available to Lender in Phoenix,
Arizona.

         3.10 Insurance and Condemnation Proceeds. Any Net Proceeds payable
with respect to a loss under any property insurance policy of any kind, now
existing or after acquired, of any Collateral, any Net Proceeds from any award
or compensation from any proceeding for the condemnation or taking by eminent
domain of any Collateral, any Net Proceeds of other involuntary conversions of
Collateral, and any portions thereof shall be payable to Lender as loss payee,
and, except as otherwise provided in this SECTION 3.10, released to Borrower
subject to any provisions of this SECTION 3.10.

                  (a) Conditions for Release of Proceeds to Borrower. Provided
         no Event of Default is then in effect and Borrower's Obligations have
         not been accelerated, Lender shall release the Net Proceeds described
         in SECTION 3.10 to Borrower, or, at the discretion of Lender, the
         Person responsible for doing the repair or supplying the replacement of
         the relevant Collateral upon receipt of a certificate from Borrower
         accompanied by appropriate


                                       20
<PAGE>   21
         evidence of the matters asserted therein that the Collateral with
         respect to which a property loss occurred has been repaired or
         replaced, or will be so repaired or replaced using such Net Proceeds,
         that the amount to be released does not exceed the cost of the repair
         or replacement, and that the amount to be released will be expended for
         such repair or replacement immediately after its release by Lender.
         Notwithstanding the foregoing, Lender shall not be required to
         authorize the release or payment of any such Net Proceeds resulting
         from any one incident where the Net Proceeds with respect to said loss,
         damage or destruction exceed $250,000.00 and where replacement or
         repair of the relevant Collateral is not necessary (in the reasonable
         judgment of Borrower) for the conduct of Borrower's on-going Primary
         Business. In any such case Lender, in its discretion, may elect to
         apply such Net Proceeds to the repayment of Borrower's Obligations (to
         be applied as if Net Proceeds from a Disposition of the relevant
         Collateral) or allow, as permitted herein, such Net Proceeds to be paid
         or released in the manner provided herein to Borrower in such amounts
         and on such terms as Lender may require.

                  (b) Proceeds Received After Acceleration of Obligations. Net
         Proceeds payable as the result of property losses, condemnation awards,
         and other involuntary conversions of Collateral and the allocation and
         distribution thereof while a notice of acceleration of Obligation is in
         effect, shall be paid to Lender. Any insurance Net Proceeds, or Net
         Proceeds from a condemnation award, or Net Proceeds of other
         involuntary conversions of assets, received by Borrower with respect to
         Collateral when a notice of acceleration of Obligations is in effect
         shall be held by Borrower in trust for Lender, shall be segregated from
         other funds of Borrower and shall, forthwith upon receipt, be turned
         over to Lender without any request from Lender, in the same form as
         received by Borrower (duly endorsed to Lender, if required), for
         application to the Borrower's Obligations.

         shall have given such assent or approval, and shall have been duly

SECTION 5 - RESTATED SECURITY AGREEMENT AND COLLATERAL

         5.1 Grant of Security Interest. It is the intention of the parties
hereto that the Obligations shall constitute one indebtedness, and shall
constitute one general obligation, including all whole or partial extensions,
renewals or replacements thereof, and including any obligation to perform or
forbear from any action as well as any obligation to pay money. To secure the
payment


                                       24
<PAGE>   25
and performance of the Obligations, and to the extent not already created in
favor of and granted to Lender, Borrower hereby creates and grants to Lender a
security interest in the Collateral.

         5.2 Borrower's Duties Regarding Collateral. Borrower agrees as follows:

                  (a) General Maintenance of Collateral. Borrower: (i) shall
         maintain the Collateral in good condition and repair (ordinary wear and
         tear and depreciation excepted) and shall not permit its value to be
         materially impaired; (ii) shall keep the Collateral free from all
         Liens (other than the Liens of ad valorem property taxes which are not
         delinquent, any statutory landlords' liens which are covered by lien
         waivers, and any Liens in favor of Lender); (iii) shall defend the
         Collateral against all claims and legal proceedings by persons other
         than Lender; (iv) shall pay and discharge when due all taxes, levies
         and other charges upon the Collateral; (v) shall not sell, lease or
         otherwise dispose of the Collateral or permit it to become a fixture or
         an accession to other goods, except for sales or leases of equipment or

         business and except as specifically authorized in this Agreement; and
         (vi) shall not permit the Collateral to be used in violation of any
         Legal Requirement or any policy of insurance. Notwithstanding the
         foregoing, Borrower may, in its sole and absolute discretion, obtain
         financing for its future acquisitions of vehicles or equipment from
         third party lenders, and grant or convey to such third party lenders
         such purchase money liens and security interests as may reasonably be
         required by such third party lenders, provided only, that the vehicles
         or equipment purchased or financed with all or part of the Proceeds of
         one or more of the Restated Loan made hereunder, shall be and remain
         free of any liens or security interests in favor of such third party
         lenders. Upon Borrower's written request, and at Borrower's cost and
         expense, Lender shall enter into intercreditor agreements or execute
         lien waivers as may reasonably be required by such third party lenders
         incident to their financing of Borrower's vehicles or equipment.

                  (b) Insurance. Borrower shall keep all Collateral and Lender's
         interest in it insured under policies with such provisions, for such
         amounts and by such insurers as shall be reasonably satisfactory to
         Lender from time to time and shall furnish evidence of such insurance
         satisfactory to Lender. Each policy shall be payable to the Borrower
         and Lender as their interests appear. Borrower assigns and directs any
         insurer to pay to Lender the Proceeds of all such insurance and any
         premium refunds, and authorizes Lender to endorse in the name of
         Borrower any instrument for such Proceeds or refunds, and to apply such
         Proceeds or refunds as provided in SECTION 3.10 hereof. Lender is
         authorized, in the name of Borrower or otherwise, to make, adjust or
         settle claims under or cancel any insurance on the Collateral.

                  (c) Lien Waivers. Borrower shall (to the extent such can be
         obtained with reasonable, good faith effort) obtain and provide to
         Lender appropriate lien waivers from all present and future lessors of
         real property upon which any of the Collateral consisting of goods or
         any other Fixed Assets is at any time located.

                  (d) Perfection and Priority. Borrower shall pay all expenses
         and, upon Lender's request, execute all writings and take all other
         actions reasonably deemed advisable by


                                       25
<PAGE>   26
         Lender to preserve the Collateral or to establish, and determine
         priority of, perfection, continued perfection or enforce Lender's
         interest in the Collateral.

                  (e) Records. Lender may examine and conduct audits of the
         Collateral and Borrower's records concerning it, wherever located, and
         make copies of such records, at any time during normal business hours,
         and Borrower shall assist Lender in so doing; provided, however,
         Borrower shall be responsible for the cost and expense of any two
         audits per calendar year. Borrower shall keep accurate, complete and
         current records respecting the Collateral. In addition to the specific
         requirements of SECTION 9, Borrower shall, within ten (10) days of any
         request by Lender, furnish to Lender a detailed statement, certified as
         being substantially accurate by an Authorized Signator, setting forth
         the current status, value and location of all or any portion of the
         Collateral.

         5.3 Collateral Inspections. Lender shall have the right (but not the
obligation) to do physical on-site examinations of the Collateral, conducted in
a reasonable manner, upon one (1) day's prior written notice to Borrower.

         5.4 Deposits. Effective on the Closing Date, Borrower hereby pledges to
Lender any and all deposits (including investment accounts) or other sums at any
time credited by or due from Lender to Borrower as security for Borrower's
Obligations, and at the direction of Lender, Lender may apply or setoff such
deposits or other sums against Borrower's Obligations at any time following a
Default as provided in SECTION 11.13, whether or not other Collateral is
adequate to pay Borrower's Obligations.

         6.1 Authority to Enter Transaction; Valid and Binding Obligation.
Borrower is fully authorized and permitted to enter into this Agreement and the

binding legal obligations of Borrower, enforceable in accordance with their
respective terms.

been designated as series A preferred, and all of which shares are issued and
outstanding, and 3,333,334 shares designated as series B preferred, none of
which is outstanding; (ii) 50,000,000 shares of common stock, 10,898,550 of
which are issued and outstanding, 5,000,000 of which are reserved for issuance
upon conversion of preferred stock and 1,494,500 of which are reserved for
issuance upon exercise of options and warrants.. Except as noted, all shares are
validly issued, fully paid and nonassessable. Shares outstanding are held of
record and beneficially owned by the Shareholders. To the best of Borrower's
knowledge, all issued and outstanding shares of capital stock of Borrower were

aggregate, at an initial exercise price of $2.00 per share, the number of
shares of common stock of Borrower equal to one


                                       26
<PAGE>   27

as of December 18, 1997; said number of shares and exercise price to be subject
to adjustments as provided in the Warrant. The common shares issuable upon
exercise of the Warrant are duly and validly authorized and reserved for
issuance and when issued (upon exercise of the Warrant in accordance with the
terms thereof) will be validly issued, fully paid and nonassessable. Borrower's
Shareholders have no preemptive rights relating to the common shares of Borrower
issuable upon the exercise of the Warrant. Borrower has created no liens,
encumbrances, equities or restrictions on the shares to be issued pursuant to
the exercise of the Warrant. Except as set forth in EXHIBIT F and except with
respect to shares of preferred stock currently authorized by the Borrower, there
are no existent preemptive or other outstanding rights, options, warrants,
conversion rights subscriptions, convertible securities calls, or other
agreements, commitments or understandings for the purchase or acquisition from
Borrower of any shares of capital stock or other securities of Borrower, or
obligating Borrower to issue any additional shares of its capital stock or any
other securities, bonds or debentures of any class, or obligating Borrower to
redeem any shares of capital stock or other securities of Borrower.

         6.3 Disclosure. To the best of Borrower's knowledge, no representation

statement furnished to Lender by or on behalf of any such Person for use in
connection with the Restated Loan Documents contains any untrue statement of a
material fact or omitted, omits or will omit to state a material fact necessary
in order to make the statements contained herein or therein not misleading in
light of the circumstances in which the same were made. The projections and pro
forma financial information contained in such materials are based upon good
faith estimates and assumptions believed by such Persons to be reasonable at the
time made, it being recognized by Lender that such projections as to future
events are not to be viewed as facts and that actual results during the period
or periods covered by any such projections may differ from the projected
results. There is no material fact known to Borrower that has had or will have a
Material Adverse Effect and that has not been disclosed herein or in such other
documents, certificates and statements furnished to Lender for use in connection
with the transactions contemplated hereby.

         6.4 Financial Condition. All financial statements concerning Borrower
which have been furnished to Lender pursuant to SECTION 4.2(b) of this Agreement
have been prepared in accordance with GAAP consistently applied throughout the
periods involved (except as disclosed therein) and do present fairly the
financial condition of Borrower as at the dates thereof and the results of their
operations for the periods then ended. The projections delivered have been
prepared by Borrower in light of the past operations of the business of
Borrower, and such projections represent the good faith estimate of senior
management of Borrower concerning the most probable course of its business as of
the date such projections are prepared and delivered.

of or suspect to exist in its favor at the time of executing this release, and
Borrower specifically the provision of any law providing that a general release

of executing the release. In that regard, Borrower expressly waive the
provisions of California Civil Code Section 1542, which provides that: "A
general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with the debtor." To
the extent permitted by law, regulation, guide or code, Borrower expressly
waives and assumes the risk of any and all Claims arising out of any matter
described or referred to in this

                                       33

Section that exist as of the date hereof, but which they do not know or suspect
to exist in their favor, whether through ignorance, oversight, error,
negligence or otherwise, and which, if known, would materially affect its
decision to enter into this Restated Loan Agreement. Borrower understands that
its release will prevent it from making any further claim against Lender or
Imperial Bank Arizona, even for damages not now known to exist, and even if the
extent of damage may actually be greater than it now understands it to be. This
Agreement has been negotiated and entered into with knowledge that such risks
exist and are assumed by Borrower.

         7.22 Subordinated Debt and Other Indebtedness Notices. Borrower shall
promptly deliver copies of all notices given or received by a Restated Loan
Party with respect to noncompliance with any term or condition related to any
Subordinated Debt and other Indebtedness, and shall promptly notify Lender of
any potential or actual event of default with respect to any Subordinated Debt
or other Indebtedness.

         7.23 Taxes and Other Liabilities. Borrower shall pay and discharge,
before the same become delinquent and before penalties or interest accrue
thereon, all taxes, assessments, and governmental charges of, upon, or against
Borrower or any of its property, and all other debts, obligations and
liabilities existing at any time, including, without limitation, all
withholdings, premiums, deposits, remittances and payments due under any
applicable federal or state law related to employment, payroll, workers'
compensation and unemployment compensation, except to the extent and so long as:
(i) the same are being contested in good faith and by appropriate proceedings in
a manner that will not have any material adverse effect upon the financial
condition of Borrower or the loss of any right of redemption from any sale
thereunder; and (ii) the Borrower shall have set aside on its books reserves
(segregated to the extent required by regulation or sound accounting practice)
deemed by Borrower and its certified public accountants to be adequate with
respect thereto.

         7.24 Trade Names. Borrower will give Lender at least thirty (30) days
advance written notice of any change of name or of any new trade name or
fictitious business name. Borrower's use of any trade name or fictitious
business name will be in compliance with all laws regarding the use of such
names.

         7.25 Use of Advances; Costs and Expenses Relating to Collateral.
Borrower shall use all Advances from the solely for permitted purposes for the
particular Advances described in this Agreement, consistent with all applicable
laws, statutes, rules and regulations. No portion of the Proceeds of any
Restated Loan shall be used by Borrower in any manner that might cause the
borrowing or the application of such Proceeds to violate or require a filing by
Lender or Borrower under Regulation G, Regulation U, Regulation T or Regulation
X or any other regulation of the Board of Governors of the Federal Reserve
System or to violate the Exchange Act. Borrower shall promptly pay all costs and
expenses relating to the Collateral, but may contest in good faith the validity
or amount thereof provided that Borrower shall have furnished Lender a cash
deposit or other appropriate security in an amount and form satisfactory to
Lender to protect Lender against the creation of any lien on, or any sale or
forfeiture of, any Collateral. Upon the final determination of Borrower, such
contest, Borrower shall promptly pay any sums determined to be due, whereupon
any deposit or security provided by Borrower shall be returned to Borrower.

         generally fails to pay, or admits in writing its inability or
         unwillingness to pay, debts as they become due; (ii) applies for the
         appointment of a trustee, receiver, sequestrator or other custodian for
         Borrower or any substantial portion of its property, or makes a general
         assignment for the benefit of creditors; (iii) in the absence of such
         application, consents or acquiesces, permits or suffers to exist the

         receiver, sequestrator or other custodian shall not be discharged
         within sixty (60) days, provided that Borrower hereby expressly
         authorizes Lender to appear in any court conducting any relevant
         proceeding during such 60-day period to preserve, protect and defend
         the rights of Lender under the Restated Loan Documents; (iv) affects or
         participates in, or permits or suffers to exist the commencement of any
         bankruptcy, reorganization, debt arrangement or other case or
         proceeding under any bankruptcy or insolvency law, or any dissolution,
         winding up or liquidation proceeding, in respect of Borrower or
         proceeding is not commenced by Borrower, such case or proceeding shall
         be consented to or acquiesced in by Borrower or shall result in the
         entry of an order for relief or shall remain for sixty (60) days
         undismissed, provided that Borrower, hereby expressly authorizes Lender
         to appear in any court conducting any such case or proceeding during
         such 60-day period to preserve, protect and defend the rights of Lender
         under the Restated Loan Documents; or (v) takes any action authorizing,

         financial or other statement or certificate contained in any Loan
         Document or other Restated Loan Document, or made or furnished to
         Lender by or on behalf of Borrower, shall be false, inaccurate or
         misleading (or there shall be any material omission) in any material
         respect as of the relevant date(s) reflected thereby.

                                       42

         to become or be declared due prior to its stated maturity.

                  (e) Failure of Security. Lender does not have or ceases to
         have a valid and perfected first priority security interest in the
         Collateral, in each case, for any reason other than the failure of
         Lender to take any action within its control.

         destruction or loss of the Equipment Collateral that is not adequately
         insured against, consisting of more than $150,000.00.

         Loan Documents for any reason, other than a partial or full release in
         accordance with the terms thereof, ceases to be in full force and
         effect or is declared to be null and void, or Borrower denies that it
         has any further liability under any Restated Loan Documents to which it

         deposits or committed Restated Loan Proceeds under this Agreement, and
         such claim or lien is not discharged, satisfied or bonded over to
         Lender's satisfaction before the earlier of: (i) forty-five (45)
         Business Days thereafter; and (ii) not less than five (5) Business Days
         prior to any sale of any portion of or interest in the Collateral

         interest therein) by Borrower, except in the ordinary course of
         business (which shall include the Disposition of obsolete or retired
         property not used or useful in its business), without the written
         consent of Lender or except as may be authorized herein.

                                       43
<PAGE>   44
                  (m) Termination of Borrower. If Borrower is dissolved,
         liquidated or terminated, without an immediate reconstitution, or
         otherwise ceases to exist.

SECTION 11 -- REMEDIES

         11.1 Acceleration. At any time when a Default shall have occurred (and
not be cured as provided in this Agreement or waived in writing by Lender) or
shall exist, without notice to, demand, presentment, protest or other
formalities of any kind, all of which are hereby expressly waived by Borrower,
Lender shall have the right to accelerate the Maturity Date of the applicable
Note and require immediate payment of the entire principal sum owing, together
with all accrued and unpaid interest, Advances, and Lender Expenses, and all
other amounts payable by Borrower hereunder; provided, however, upon the
occurrence of a Default under SECTION 10.1 (c), (g) and (i) the entire amount of
Borrower's Obligations shall be deemed fully due and payable without notice to,
demand, presentment, protest or other formalities of any kind, all of which are
expressly waived by Borrower.

         11.2 Advances to Protect Lender's Interests. Regardless whether a
Default or Potential Default shall have occurred or exist, with notice to be
given Borrower as promptly as is practicable (and, in advance, if practicable),
Lender shall have the right but not the obligation, at any time to advance to
any Person any sum which Lender in its judgment deems necessary to protect or
preserve the Collateral or Lender's security interests in or liens on the
Collateral (or the priority thereof), or to cure any Default which shall then
exist. Each such Advance shall constitute a part of Borrower's Obligations and
shall be secured by the Collateral and, at Lender's election, shall either be
reimbursed to it by Borrower immediately upon demand or added to Borrower's
Obligations balance and bear interest at the Default Rate under the Facility
Note. It is understood and agreed that nothing herein contained shall obligate
Lender to make any such advance, nor shall the making of one or more such
advances constitute an agreement by Lender to make any further advance or be
deemed a waiver of any Default by Borrower under the terms hereof or of any
other Restated Loan Document. Lender shall seasonably inform Borrower of any
such advance, but failure to so inform or delay therein shall not limit or
otherwise affect Borrower's obligation under this SECTION 11.2 to reimburse such
advance or to pay interest thereon.

         11.3 Application of Proceeds. Upon the occurrence and during the
continuance of an Event of Default, the Proceeds of any sale of, or other
realization upon, all or any part of the Collateral shall be applied: first, to
all Lender Expenses incurred by Lender; second, to accrued and unpaid interest
on the Obligations; third, to the principal amounts of the Obligations
outstanding; and fourth, to any other indebtedness or obligations of Borrower
owing to Lender.

         11.4 Cessation of Funding. Lender shall have the right to cease making
any disbursements hereunder or pursuant to any of the other Restated Loan
Documents.

         11.5 Collection of Accounts and Payments. Upon the occurrence of an
Event of Default and at any time while an uncured or non-waived Event of Default
exists, if requested by Lender, Borrower shall establish such lock boxes and
depository accounts ("BLOCKED ACCOUNTS") in Borrower's name with such banks as
are acceptable to Lender (subject to Bank Agency Agreements and to irrevocable
instructions acceptable to Lender as hereinafter set forth) to which all account
debtors shall directly remit all payments on accounts and in which Borrower will

                                       44
<PAGE>   45
immediately deposit all cash payments made for inventory or other cash payments
constituting Proceeds of Collateral in the identical form in which such payment
was made, whether by cash or check. Borrower hereby agrees that all immediately
available funds received in the Blocked Accounts shall on the Business Day of
receipt be forwarded to Lender. All payments received by Lender, whether by
cash, check, wire transfer or any other instrument, made to such Blocked
Accounts or otherwise received by Lender and whether on the accounts or as
Proceeds of other Collateral or otherwise will be the sole and exclusive
property of Lender. Lender may settle, compromise, extend or renew the
indebtedness of such account debtors. Borrower hereby constitutes and appoints
Lender and all Persons designated by Lender for that purpose as the Borrower's
true and lawful attorney-in-fact, with power to endorse Borrower's name to any
of the items of payment or Proceeds described in this SECTION 11.5, and all
Proceeds of Collateral that come into Lender's possession or under Lender's
control. Both the appointment of Lender as Borrower's attorney and Lender's
rights and powers are coupled with an interest and are irrevocable until payment
in full and complete performance of all of the Obligations. Borrower, and any of
its Affiliates, employees, agents or other Persons acting for or in concert with
Borrower, shall, acting as trustee for Lender, receive, as the sole and
exclusive property of Lender, any monies, checks, notes, drafts or any other
payments relating to and/or Proceeds of accounts or other Collateral which come
into the possession or under the control of Borrower or any of Borrower's
Affiliates, employees, agents or other Persons acting for or in concert with
Borrower, and immediately upon receipt thereof, Borrower or such Persons shall
remit the same or cause the same to be remitted, in kind, to the Blocked
Accounts or to Lender at its address set forth in SECTION 12.14 below.

         11.6 Cure Period. Upon the occurrence of an Event of Default under
SECTION 10.1(k), Lender shall not be entitled to declare the Obligations
immediately due and payable prior to the Restated Maturity Date of any relevant
Obligation(s) unless Borrower fails to cure the Event of Default within five (5)
days after Lender gives written notice to Borrower as provided by SECTION 12.25
hereof, reasonably specifying the nature of the Events of Default. Upon the
occurrence of an Event of Default under SECTIONS 10.1 (d), (h), (i), or (j),
Lender shall not be entitled to declare the Obligations immediately due and
payable prior to the final maturity date of any relevant Obligation(s) unless
Borrower fails to cure the relevant Event(s) of Default within thirty (30) days
after Lender gives written notice to Borrower as provided by SECTION 12.25
hereof, reasonably specifying the nature of the Event(s) of Default. The thirty
(30) day period described in the foregoing sentence shall be extended for an
additional sixty (60) days (for a total of ninety (90) days) if: (a) the
relevant Event(s) of Default are reasonably capable of being cured, but not
within thirty (30) days and not by the payment of monies; and (b) Borrower
immediately commences to take and diligently pursues all reasonable steps to
cure such Event(s) of Default, except as provided in SECTION 10.1 hereof.
Notwithstanding any conflicting provision of this SECTION 11.6, no notice shall
be required or cure period provided with respect to any other Event(s) of
Default.

         11.7 Default Interest. During any period that there exists a Default in
payment due under any of the Restated Loan Documents, unless the same is waived
in writing by Lender, and during any period when a notice of acceleration of
Obligation is in effect, interest on the unpaid balance of the Notes shall
accrue at the Default Rate.

                                       45
<PAGE>   46
         11.8 Duty of Lender with Respect to Collateral. Beyond the safe
custody thereof, Lender shall have no duty with respect to any Collateral in
its possession or control (or in the possession or control of any agent or
bailee) or with respect to any income thereon or the preservation of rights
against prior parties or any other rights pertaining thereto. Lender shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which Lender accords its own property, provided,
however, Lender shall have no duty or obligation to protect, insure, collect or
realize upon the Collateral or preserve rights in it against prior parties.
Lender shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by Lender in good faith. Borrower releases Lender from,
and shall indemnify Lender against, any liability for any act or omission
relating to the Collateral, except for any liability directly resulting from
Lender's gross negligence or willful misconduct.

         11.9 General Remedies. At any time when a Default shall have occurred
or exists, or if any Obligation matures by its terms and is not then fully paid,
without any further notice (except as may be required by specific applicable
laws such as those requiring notices of intended Dispositions of certain
Collateral), and in addition to all rights and remedies provided for under the
Restated Loan Documents, Lender shall have all rights and remedies provided to
it by law, and, without limiting the generality of the foregoing, Lender may do
any one or more acts described in this SECTION 11.9, this Agreement or in the
other Restated Loan Documents and in any order they deem appropriate. Lender
shall exercise all rights, powers and remedies afforded it under the Restated
Loan Documents in good faith, unless the exercise of such rights, powers and
remedies is stated to be in Lender's sole and absolute discretion. To the extent
that the Collateral consists of personal property rights and interests, Lender
may exercise any or all of the remedies of a secured party under the UCC (and/or
any other relevant state(s)' Uniform Commercial Code) with respect to such
personal property. If Lender should proceed to dispose of or otherwise realize
upon any such personal property in accordance with the provisions of the UCC,
unless the Collateral is perishable or threatens to decline speedily in value,
ten (10) days notice by Lender to Borrower or any other "debtor" entitled to
notice under the UCC shall be deemed to be commercially reasonable notice under
any provision of the UCC requiring notice.

         11.10 License of Intellectual Property. Borrower hereby assigns,
transfers and conveys to Lender, effective upon the occurrence of any Event of
Default hereunder, the non-exclusive right and license to use all Intellectual
Property owned or used by it together with any goodwill associated therewith,
all to the extent necessary to enable Lender to realize on the Collateral and
any successor or assign to enjoy the benefits of the Collateral. This right and
license shall inure to the benefit of all successors, assigns and transferees of
Lender and its successors, assigns and transferees, whether by voluntary
conveyance, operation of law, assignment, transfer, foreclosure, transfer in
lieu of foreclosure or otherwise. Such right and license is granted free of
charge, without requirement that any monetary payment whatsoever be made to
Borrower by Lender.

         11.11 Other Remedies. Lender shall have the right to exercise any other
right, privilege or remedy available to Lender under any of the Restated Loan
Documents, under any other agreement or instrument or as may be provided by
applicable law or in equity. Lender shall have the

                                       46
<PAGE>   47
right to enforce any one or more of the remedies provided hereunder or by law or
in equity either successively or concurrently, and any such action by Lender
shall not be deemed an election of remedies or otherwise prevent Lender from
pursuing any further remedy it may have hereunder or at law or in equity, except
as otherwise required by applicable law.

         11.12 Power of Attorney. All assignments and grants of liens to Lender
made or contemplated by SECTION 5 include, inter alia, all powers, rights and
privileges that are now or hereafter possessed by Borrower in and to the
Collateral. Borrower hereby makes, constitutes and appoints Lender the true and
lawful attorney-in-fact of Borrower, in the name, place and stead of Borrower,
or otherwise, upon the occurrence of any Event of Default which remains uncured
or not waived following the receipt of a notice pursuant to SECTION 12.25:

                  (a) To take all actions and to execute, acknowledge, obtain
         and deliver any and all writings necessary or deemed advisable by
         Lender in order to exercise any rights of Borrower with respect to the
         Collateral or to receive and enforce any payment or performance due to
         Borrower with respect to the Collateral;

                  (b) To give any notices, instructions or other communications
         to any Person or entity in connection with the Collateral;

                  (c) To demand and receive all performances due under or with
         respect to the Collateral and to take all lawful steps to enforce such
         performances and to compromise and settle any claim or cause of action
         of Borrower arising from or related to the Collateral and give
         acquittances and other discharges relating thereto; and

                  (d) To file any claim or proceeding or to take any other
         action, in the name of Lender, Borrower or otherwise, to enforce
         performances due under or related to the Collateral or to protect and
         preserve the right, title and interest of Lender thereunder.

The foregoing power of attorney is a power coupled with an interest and shall be
irrevocable and unaffected by the disability of the principal so long as any
portion of the Obligations remains contingent, unmatured, unliquidated, unpaid
or unperformed. Lender shall have no obligation to exercise any of the foregoing
rights and powers in any event.

         11.13 Set Off Rights. Lender is hereby granted a continuing security
interest in, and shall have the right, without notice to Borrower to set off and
apply against Borrower's Obligations, any deposits (general or special, time or
demand, provisional or final) or funds held by it for the account of Borrower,
for so long as a Default shall exist and remain uncured, to the full extent of
the indebtedness owed with respect to Borrower's Obligations, and the aforesaid
security interest and right of set off may be exercised against Borrower or
against any trustee in bankruptcy, debtor in possession, assignee for the
benefit of creditors, custodian, sequestrator, receiver, or execution, judgment
or attachment creditor of Borrower, or against anyone else claiming through or
against Borrower or such trustee in bankruptcy, debtor in possession, assignee
for the benefit of creditors, custodian, sequestrator, receiver, or execution,
judgment or attachment creditor, notwithstanding the fact that such right of set
off shall not have been exercised by Lender prior to the making, filing or
issuance, or service upon Lender of, or of notice of, any petition seeking any
such relief or remedy, any assignment for the benefit of creditors, an
appointment or application

                                       47
<PAGE>   48
for the appointment of a custodian, sequestrator or receiver, or the issuance of
execution, subpoena, order or warrant. Lender agrees promptly to notify Borrower
after any such set off and application made by it, provided that neither failure
to give such notice nor delay therein shall affect the validity of such set off
and application. It is understood that the cumulative right of set off granted
hereby shall not exceed in the aggregate the full indebtedness owing with
respect to Borrower's Obligations. Borrower hereby agrees, to the fullest extent
permitted by law, that any Lender or holder or participant may exercise its
right of setoff with respect to amounts in excess of its pro rata share of the
Obligations (or, in the case of a Lender or participant, in excess of its pro
rata participation interest in the Obligations) and that such Lender or holder
or participant, as the case may be, shall be deemed to have purchased for cash
in the amount of such excess, participations in each other Lender or holder's
share of the Obligations.

         11.14 Specific Performance. Lender shall have the right to institute
appropriate proceedings to specifically enforce performance of the terms and
conditions of all or any of the Restated Loan Documents.

         11.15 Waivers, Non-Exclusive Remedies. No failure on the part of Lender
to exercise, and no delay in exercising and no course of dealing with respect
to, any right under this Agreement or the other Restated Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise by Lender
of any right under this Agreement or any other Restated Loan Document preclude
any other or further exercise thereof or the exercise of any other right. The
rights in this Agreement and the other Restated Loan Documents are cumulative
and are not exclusive of any other remedies provided by law.

SECTION 12 -- MISCELLANEOUS

         12.1 Advice of Counsel. Borrower acknowledges that it has received a
copy of this Agreement as executed and that it has had the opportunity to seek,
and has in fact sought, the advice and benefit of legal counsel prior to
executing this Agreement.

         12.2 Assignability by Borrower. Borrower shall not sell, assign,
transfer or otherwise convey any of its rights or delegate any of its
obligations or duties under this Agreement or any of the other Restated Loan
Documents. Any attempted sale, assignment, transfer, conveyance or delegation in
violation of this SECTION 12.2 shall be void and a Default under SECTION 10.1.

         12.3 Assignments and Participations by Lender. Lender may assign its
rights and delegate its obligations under this Agreement and further may assign,
or sell participations in, all or any part of the Restated Loan, the Commitments
or any other interest herein to an Affiliate or to another Person; provided,
Lender retains an interest in the Restated Loan and Commitments and continues as
the servicing agent for such assignees and participants. In the case of an
assignment authorized under this SECTION 12.3, the assignee shall have, to the
extent of such assignment, the same rights, benefits and obligations as it would
if it were a Lender hereunder. Lender shall be relieved of its obligations
hereunder with respect to the Commitments or assigned portion thereof. Borrower
hereby acknowledges and agrees that any assignment will give rise to a direct
obligation of Borrower to the assignee and that the assignee shall be considered
to be a "Lender." Lender may furnish any information concerning Borrower in its
possession from time to time to assignees and participants (including
prospective assignees and participants).

                                       48

         12.4 Binding Effect. This Agreement shall be binding upon and inure to
the benefit of the parties hereto and, subject to SECTION 12.2, their respective
successors and assigns.

         12.5 Brokers. Borrower and Lender each warrant and represent to the
other that they have dealt with no mortgage broker or finder with respect to the
Restated Loan. Each party indemnities and holds the other harmless from any and
all claims for broker's or finder's fees relating to the Restated Loan alleged
to be due as a result of the acts of the indemnifying party.

         12.6 Claims Resolution.

                  (a) Other than matters involving the appointment of a

         dispute or claim between or among the parties hereto arising out of or
         relating to this Agreement (individually and collectively, a "CLAIM")
         which is not settled in writing within thirty (30) days after the date
         on which a party subject to this Agreement gives written notice to all
         other parties that a Claim exists (the "CLAIM DATE"), will be settled
         by a "REFERENCE PROCEEDING."

                  (b) "REFERENCE PROCEEDING" means a proceeding in California in
         accordance with the provisions of Section 638 et seq. of the California
         Code of Civil Procedure, or their successor section ("CCP"), which
         shall constitute the exclusive remedy for the settlement of any Claim
         concerning this Agreement, including whether such controversy, dispute
         or claim is subject to the reference proceeding. Except as set forth
         above, the parties waive their rights to initiate any legal proceedings
         against each other in any court or jurisdiction other than Los Angeles
         County (the "COURT").

                  (c) The referee shall be a retired Judge of the Court selected
         by mutual Agreement of the parties, and if they cannot so agree within
         forty-five (45) days after the Claim Date, the Presiding Judge of the
         Court (or his representative) shall promptly select the referee. The
         referee shall be appointed to sit as a temporary judge, with all of the
         powers for a temporary judge, as authorized by law, and upon selection
         should take and subscribe to the oath of office as provided for in Rule
         244 of the California Rules of Court (or any subsequently enacted
         Rule). Each party shall have one peremptory challenge pursuant to CCP
         Section 170.6.

                  (d) The referee shall (i) be requested to set the matter for
         hearing within sixty (60) days after the Claim Date and (ii) try any
         and all issues of law or fact and report a statement of decision upon

         decision rendered by the referee will be final, binding and conclusive
         and judgment shall be entered pursuant to CCP Section 644 in any court
         in the State of California having jurisdiction.

                  (e) Any party may apply for a reference proceeding at any time

                  (f) All discovery permitted by this Agreement shall be
         completed no later than fifteen (15) days before the first hearing
         date established by the referee. The referee may extend such period in
         the event of a party's refusal to provide requested discovery for any
         reason whatsoever, including, without limitation, legal objections
         raised to such discovery or unavailability of a witness due to absence
         or illness. No party shall be entitled to "priority" in conducting
         discovery. Either party upon seven (7) days written notice may take
         depositions, and request for production or inspection of documents
         shall be responded to within ten (10) days after service. All disputes
         relating to discovery which cannot be resolved by the parties shall be
         submitted to the referee whose decision shall be final and binding upon
         the parties. Pending appointment of the referee as provided herein, the
         Superior Court is empowered to issue temporary and/or provisional
         remedies, as appropriate.

                  (g) Except as expressly set forth in this Agreement, the
         referee shall determine the manner in which the reference proceeding is
         conducted including the time and place of all hearings, the order of
         presentation of evidence, and all other questions that arise with
         respect to the course of the reference proceeding. All proceedings and
         hearings conducted before the referee, except for trial, shall be
         conducted without a court reporter, except that when any party so
         requests, a court reporter will be used at any hearing conducted before
         the referee. The party making such a request shall have the obligation
         to arrange for and pay for the court reporter. The costs of the court
         reporter at the trial shall be borne equally by the parties.

                  (h) The referee shall be required to determine all issues in
         accordance with existing case law and the statutory laws of the State
         of California. The rules of evidence applicable to proceedings at law
         in the State of California will be applicable to the reference
         proceeding. The referee shall be empowered to enter equitable as well
         as legal relief, to provide all temporary and/or provisional remedies
         and to enter equitable orders that will be binding upon the parties.
         The referee shall issue a single judgment at the close of the reference
         proceeding that shall dispose of all of the claims of the parties that
         are the subject of the reference.

                  (i) The parties hereto expressly reserve the right to contest
         or appeal from the final judgment or any appealable order or appealable
         judgment entered by the referee. The parties hereto expressly reserve
         the right to findings of fact, conclusions of law, a written statement
         of decision, and the right to move for a new trial or a different
         judgment, which new trial, if granted, is also to be a reference
         proceeding under this provision.

                  (j) In the event that the enabling legislation which provides
         for appointment of a referee is repealed (and no successor statute is
         enacted), any dispute between the parties that would otherwise be
         determined by the reference procedure herein described will be resolved
         and determined by arbitration. The arbitration will be conducted by a
         retired judge of the Court, in accordance with the California
         Arbitration Act, Section 1280 through Section 1294.2 of the CCP as
         amended from time to time. The limitations with respect to discovery as
         set forth hereinabove shall apply to any such arbitration proceeding.

         12.7 Confidentiality. Prior to the Restated Closing Date, neither
Lender nor Borrower shall disclose or in any way publish any information or
make publicity releases regarding the proposed transaction except to their
respective counsel, accountants and such other parties as would need to know for
them to proceed with appropriate due diligence. Upon the execution and delivery
of this Agreement, either of the parties may disclose and make public the fact
of this financing provided that such disclosure shall not include disclosure of
rates, particular terms or covenants without the prior written consent of
Lender, which consent Lender may withhold in its sole and absolute discretion.

         12.8 Consent and Approval by Lender. In any instance under the Restated
Loan Documents where Lender's approval or consent is required or the exercise of
Lender's judgment is required, the granting or denial of such approval or
consent and the exercise of such judgment shall be subject to the obligation of
Lender to act in good faith, unless the matter is expressly provided to be
within the sole discretion of Lender, in which event, as to such matters, Lender
shall not, for any reason or to any extent, be required to grant such approval
or consent or exercise such judgment in any particular manner.

          12.9 Construction of Agreement. This Agreement shall apply to the
parties hereto according to the context hereof, without regard to the number or
gender of words or expressions used herein. The headings or captions of parts
and Sections in this Agreement are for convenience and reference only, and in no
way define, limit or describe the scope or intent of this Agreement or the
provisions of such Parts or Sections. This Agreement shall be construed as a
whole, in accordance with the fair meaning of its language, and, as each party
has been represented by legal counsel of its choice in the negotiation of this
Agreement, neither this Agreement nor any provision thereof shall be construed
for or against either party by reason of the identity of the party drafting
this Agreement. As used in this Agreement, the term(s): (a) "INCLUDING" shall
mean without limitation by reason of enumeration; (b) "HEREIN", "HEREUNDER",
"HEREOF", "HEREINAFTER" or similar terms refer to this Agreement as a whole
rather than to any particular Section or Section; and (c) "MONTH" means a
calendar month unless otherwise provided. Unless otherwise expressly provided in
this Agreement or another Restated Loan Document, the provisions of this
Agreement shall prevail in the event that an irreconcilable conflict or
discrepancy exists between the provisions of this Agreement and the provisions
of any other Restated Loan Document, and specific provisions of the Restated
Loan Documents that irreconcilably conflict with general provisions of the same
or another Restated Loan Document that is not otherwise entitled to priority in
construction shall prevail over the general provisions. Technical words and
phrases and those that have acquired particular meanings in the banking, real
estate and construction industries shall be construed according to those
particular meanings when the context in which they are used in this Agreement
reasonably indicates that the technical meaning is intended.

         12.10 Counterparts. This Agreement and any other Restated Loan Document
may be executed in any number of counterparts, each of which, when executed and
delivered, shall be an original, but all of which shall together constitute one
and the same agreement.

         12.11 Expenses and Attorneys' Fees. Whether or not the transactions
contemplated hereby shall be consummated (provided, any failure to consummate is
not Lender's fault) Borrower agrees to promptly pay all of Lender's Expenses in
connection with any matters contemplated by or arising out of this Agreement or
the other Restated Loan Documents.

         12.12 Further Documents and Acts. Borrower, upon the request of Lender,
shall execute and deliver such further writings, and take such further actions
as may be reasonably necessary to carry out the intent of this Agreement and to
perfect and preserve the rights, interests and priority of Lender hereunder.

         12.13 General Immunity. Lender shall have no liability to Borrower, or
any other Person for: (i) any loss, costs or expenses incurred by Borrower in
connection with any drafts, documents or instruments delivered by Borrower to
Lender in connection herewith; (ii) any negligence, misfeasance, suspension,
misconduct, insolvency, or bankruptcy of any correspondent or agent of Lender to
whom any such drafts, documents or instruments may be entrusted, unless caused
by such correspondent's or agent's gross negligence or willful misconduct; (iii)
any loss or delay, in transmission or otherwise, of any such drafts, documents
or instruments or the Proceeds thereof; or, (iv) any delay, interruption,
omission or error in transmission or delivery of any message; provided, however,
that nothing herein contained shall be deemed to release Lender from liability
on account of any gross negligence or willful misconduct by Lender, nor to
release any obligation under any of the Restated Loan Documents of Lender.

         12.14 Governing Law. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF CALIFORNIA AND THE VALIDITY OF THIS AGREEMENT AND THE
CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF, AND THE RIGHTS OF THE
PARTIES HERETO SHALL SPECIFICALLY, EXCEPT AS OTHERWISE PROVIDED HEREIN, BE
DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF CALIFORNIA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

         12.15 Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, Lender shall not be obligated to do anything in
violation of any limitation or prohibition provided by any applicable statute or
regulation.

         12.16 Headings. All sections and descriptive headings of subsections
in this Agreement are inserted for convenience only, and shall not affect the
construction or interpretation hereof.

         12.17 Incorporation of Recitals and Exhibits. The recitals hereto
together with all Exhibits attached hereto are hereby incorporated herein and
made a part hereof for all purposes, and references in this Agreement to such
recitals and Exhibits shall be deemed to include this reference and
incorporation.

         12.18 Indemnification.

                  12.18.1. Scope of Indemnity. Borrower hereby indemnifies
         Lender, and its past and current officers, directors, employees,
         attorneys and agents, and their respective successors and assigns
         (collectively, the "INDEMNITEES), from and against any and all
         out-of-pocket loss, expenses, charges, fees (and including reasonable
         attorneys' fees of independent and in-house counsel) and liability, and
         agrees to hold Indemnitees harmless from any and all out-of-pocket
         damages, costs, expenses, claims, demands, and liabilities which may be
         asserted or alleged against any of them in connection with or arising
         out of (i) the Borrower's Obligations; and (ii) the administration or
         enforcement of or the exercise

                                       52
<PAGE>   53
         of any right under the original Loan Documents or the Restated Loan
         Documents (including, without limitation, in connection with or as a
         result of any sale, use, operation, lease, Disposition or consumption
         of any of the Collateral as long as such is done in a commercially
         reasonable manner); whenever asserted, and for all reasonable
         out-of-pocket expenses (and including reasonable attorneys' fees of
         independent and in-house counsel) and all out-of-pocket costs of
         compromise or settlement which may be incurred by Indemnitees on
         account of or arising out of or in connection with any such claim,
         demand or obligation. In each case, such losses or expenses shall
         include, but not be limited to, any such loss or expense arising from
         interest or fees payable by an Indemnitee to lenders of funds obtained
         by it in order to maintain Advances hereunder and the cost of
         liquidating any time deposit prior to the maturity thereof. A
         certificate as to any additional amounts payable pursuant to this
         Section submitted by Lender to Borrower shall be conclusive, absent
         manifest error.

                  12.18.2. Survival of Indemnity Obligation. This covenant shall
         survive termination of the original Loan Agreement, this Agreement and
         the payment of the original Notes and the Facility Note. The foregoing
         indemnity shall extend to claims, demands or obligations, and
         out-of-pocket expenses relating thereto and out-of-pocket costs of
         compromise or settlement thereof, but not to those resulting from the
         gross negligence of or willful misconduct by any Indemnitee.

                  12.18.3. Tender of Defense. In the event that any action or
         proceeding is brought against an Indemnitee arising out of Borrower's
         Obligations, the administration or enforcement of the Restated Loan
         Documents or the exercise of any right under the Restated Loan
         Documents, Borrower shall, upon notice from the Indemnitee, resist and
         defend such action or proceeding on behalf of the Indemnitee; provided
         that failure of such party to give such notice shall not relieve
         Borrower from any of its obligations under this Section unless such
         failure prejudices defense of such action or proceeding by Borrower. At
         its own expense, an Indemnitee may employ separate counsel and
         participate in the defense.

                  12.18.4. Conflicts of Interest. If employment of separate
         counsel is required because of a conflict of interest between Borrower
         and the indemnified party or among the indemnified parties, or the
         failure of Borrower, after receipt of notice, to assume the defense,
         then the indemnified party may employ separate counsel at Borrower's
         expense.

                  12.18.5. Compromise and Settlement. Borrower shall not be
         liable for any compromise or settlement without its consent unless
         Borrower shall have failed to perform any of its obligations under this
         SECTION 12.18.

                  12.18.6. Unenforceability of Indemnity Undertaking. If and to
         the extent that the undertaking described in this SECTION 12.18 may be
         unenforceable for any reason, Borrower hereby agrees to make the
         maximum contribution to the payment and satisfaction of indemnified
         liabilities which is permissible under applicable law.

         12.19 Interest Limit. All Restated Loan Documents and all other
agreements between Borrower and Lender are hereby expressly limited so that, in
no event whatsoever, whether by

                                       53
<PAGE>   54
reason of deferment in accordance with any Restated Loan Document(s) or any
other present or future agreement, or advancement of the Proceeds of any
Restated Loan acceleration or maturity of any Obligation, or otherwise, shall
the total amount paid or agreed to be paid to Lender for the loan, use,
forbearance, detention, funding or issuance of any financial accommodations
described herein, including, without limitation, all interest, any commitment,
loan, consent or extension fees, all late charges, all values of deposit
accounts, and all reimbursable charges, expenses and costs which may be treated
as interest, exceed the total maximum permissible amount(s), if any, under
applicable law. If, from any circumstance whatsoever, fulfillment of any
provision of any Restated Loan Document or any such other agreement would
require Borrower to pay amounts in excess of the maximum amounts, if any,
lawfully collectible under applicable law, then, ipso facto, the obligation of
Borrower to be fulfilled shall be reduced to the require the payment of only
the maximum amounts lawfully collectible. To the extent that Borrower have the
power to do so, Borrower agrees that the only laws relevant to maximum
permissible interest shall be the substantive internal laws of the State of
Arizona in effect on the date of this Agreement. All interest and other charges,
fees, things of value and reimbursable costs and expenses which Borrower is or
may become obligated to pay or reimburse in connection with the financial
accommodations described herein and which constitute "interest" shall constitute
items of interest in addition to the rate(s) of interest specified in the
Restated Loan Documents, which Borrower hereby contracts in writing to pay, and
shall constitute additional "rates of interest" for purposes of determining
compliance with such statutes. Notwithstanding anything herein or in any of the
other Restated Loan Documents to the contrary, if any charge or fee for which
Borrower is or becomes obligated in connection with the Restated Loan Documents
constitutes interest and is not otherwise stated as a rate, such charge or fee
shall be deemed an additional rate of interest to which Borrower agrees,
computed by dividing the amount of such charge or fee by the principal amount of
the Notes. This provision shall control every agreement between Borrower and
Lender pertaining to Borrower's Obligations. In the event any amount determined
to be excessive interest is applied against the unpaid principal balance of
Borrower's Obligations, and thereafter the rate of interest accruing on
Borrower's Obligations is less than the rate permitted by law, Borrower's
Obligations shall thereafter accrue interest at such highest lawful rate until
such time as the amount accrued at the interest rate differential equals the
amount of excessive interest previously applied against principal.

         12.20 Lender's Agents. All attorneys, accountants, appraisers, and
other professional Persons and consultants retained by Lender shall have the
right to act exclusively in the interest of Lender and shall have no duty of
disclosure, duty of loyalty, duty of care, or other duty or obligation of any
type or nature whatsoever to Borrower or any of Borrower's shareholders or any
other Person.

         12.21 Marshaling; Payments Set Aside. Lender shall not be under any
obligation to marshal any assets in favor of any Restated Loan Party or any
other party or against or in payment of any or all of the Obligations. To the
extent that any Restated Loan Party makes a payment or payments to Lender or
Lender enforces its Security interests or exercise its rights of setoff, and
such payment or payments or the Proceeds of such enforcement or setoff or any
part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside and/or required to be repaid to a trustee, receiver or
any other party under any bankruptcy law, state or federal law, common law or
equitable cause, then to the extent of such recovery, the Obligations or part
thereof

                                       54
<PAGE>   55
originally intended to be satisfied, and all Liens, rights and remedies
therefor, shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

         12.22 Modification and Waiver. No provision of this Agreement shall be
amended, or modified except by an instrument in writing signed by Borrower and
Lender. No provision of this Agreement shall be waived except by an instrument
in writing signed by Borrower and Lender. Unless and until Lender has received
written notice from Borrower that such authorization has been revoked with
respect to that Borrower, any Authorized Signator shall be authorized to execute
any amendment on behalf of Borrower. Any and all prior oral and/or written
commitments from Lender to Borrower, any Related Person or any predecessor in
interest of Borrower, any Related Person or any principals or agents thereof
with respect to all or any portion of the financing described in this Agreement
have been merged in the Restated Loan Documents and shall, except as expressly
provided in the Restated Loan Documents, be of no further force or effect.
Lender shall not be deemed to have waived any rights with respect to the
obligations secured or the Collateral unless such waiver be in writing and
signed by Lender. No delay or omission on the part of Lender in exercising any
right shall operate as a waiver of such right or any other right. A waiver on
any one occasion shall not be construed as a bar to the exercise of any right on
any future occasion. All rights and remedies of Lender as to Borrower's
Obligations or the Collateral, whether evidenced hereby or by any other
instrument or papers shall be cumulative and may be exercised singularly or
concurrently. The waiver by Lender of any breach or Default by Borrower under
any of the terms of any of the Restated Loan Documents shall not be deemed to be
a waiver of any subsequent breach or Default on the part of Borrower under the
same or any other of the Restated Loan Documents.

         12.23 No Agency, Fiduciary or Partnership Relationship. Borrower
acknowledges and agrees that no agency, fiduciary, representative or partnership
relationship exists between Lender, on the one hand, and Borrower, on the other
hand.

         12.24 No Other Parties to Benefit. The Restated Loan Documents are made
for the sole benefit of Borrower and Lender, and, subject to SECTIONS 12.2 AND
12.3, their respective successors and assigns, and no other Person is intended
to or shall have any rights or benefits hereunder, whether as third-party
beneficiary or otherwise, except as otherwise expressly provided therein.

         12.25 Notices. All notices and other communications provided for
hereunder shall be in writing (including telegraphic, telecopy or other
facsimile communication) and mailed, telegraphed, telexed, cabled, telecopied
(or communicated by other means of facsimile transmission) or delivered (by hand
or by courier service), to the parties at their respective addresses set forth

cabled or telecopied, be effective upon the earlier to occur of actual receipt
or two (2) Business Days after deposit in the mail (postage prepaid), or upon
delivery to the telegraph company, or upon confirmation by telex answerback, or
upon delivery to the cable company or upon confirmation at the established
confirmation number, respectively. Lender's giving of notice to Borrower under
the Restated Loan Documents shall not be required in any instance in which the
giving of such notice is prohibited by the provision of 11 U.S.C. Section 362.

         12.26 Other Actions and Documents. At any time and from time to time,
Borrower agrees to take, without further consideration, such actions and to
execute and deliver such documents as Lender deems necessary to effectuate the
purposes of this Agreement.

         12.27 Ratification of Loan Documents; Integration. Borrower and Lender
hereby ratify all Loan Documents and the terms, conditions and provisions
thereof except as specifically amended hereby. This Agreement and the Restated
Loan Documents constitute a complete integration of the agreement of Lender and
Borrower respecting the Restated Loan.

         12.28 Reinstatement of Liabilities. In the event that any time after
the Restated Closing Date Lender is for any reason compelled to surrender to any
Person all or any portion of the Collateral or any payments received by them as
contemplated by the original Loan Agreement, this Agreement, the Notes, the
Facility Note, the original Loan Documents, or the Restated Loan Documents,
because the same (or any portion thereof) is determined to be void or voidable
as a fraudulent transfer or conveyance or a preference, or a diversion of trust
funds or for any other reason, then, to the extent such Collateral or such
payments, note or any other payments are

                                       56
<PAGE>   57
compelled to be surrendered, any Debt deemed to have been satisfied and
discharged, and (as applicable) the Restated Loan Documents and any promissory
notes which have been cancelled, as the case may be, will be reinstated with the
same force and effect as though they had continued in full force and effect
notwithstanding the receipt of such Collateral or such payments, and any action
taken by Lender in reliance upon or by reason of the receipt of such Collateral
or such payment or payments shall be without prejudice to Lender's rights under
the original Loan Documents or the Restated Loan Documents, and any promissory
notes, as the case may be, and such action shall be deemed to have been
conditioned upon the receipt of such Collateral or such payment or payments to
Lender having become final and irrevocable.

         12.29 Rights Unimpaired. ABSENT FULL AND TIMELY PERFORMANCE OF THE
RESTATED LOAN DOCUMENTS BY BORROWER, NOTHING CONTAINED HEREIN SHALL BE DEEMED A
WAIVER OF ANY CAUSE OF ACTION, CLAIM, RIGHT OR REMEDY WHICH LENDER HAS AGAINST
BORROWER AND ITS OFFICERS, DIRECTORS AND EMPLOYEES, BY REASON OF THE
CIRCUMSTANCES AND EVENTS GIVING RISE TO BORROWER'S OBLIGATIONS.

         12.30 Right to Appear in Litigation. Lender shall have the right to
commence, appear in or defend any action or proceeding which Lender, in good
faith, believes may affect the rights or duties of any of the parties hereunder
or in connection herewith or in and to the Collateral. If no Default shall
exist hereunder, Lender shall give notice to Borrower of its intent to exercise
its rights hereunder, and, if Borrower fails, within five (5) Business Days, to
diligently commence, appear in or defend any action or proceeding which Lender
sets forth in its notice to Borrower, then Lender may commence such action or
appear in or defend any action or proceeding then pending. In the event Lender
exercises its rights hereunder, then Borrower agrees to pay all necessary and
reasonable out-of-pocket expenses incurred by Lender in connection therewith
(including, but not limited to, reasonable attorneys' fees of independent and
in-house counsel).

         12.31 Severability; Integration; Form and Substance of Documents;
Time of the Essence. Inapplicability or unenforceability of any provision of the
Restated Loan Documents shall not limit or impair the operation or validity of
any other provision of the Restated Loan Documents. The Restated Loan Documents
constitute the entire agreement between the parties with respect to the subject
matter hereof. Restated Loan Documents is intended to represent the mutual
intent of the parties thereto and no rule of strict construction shall be
applied against any party. TIME IS OF THE ESSENCE OF THIS AGREEMENT AND OF THE
RESTATED LOAN DOCUMENTS.

         12.32 Taxes and Expenses. Any taxes (excluding income taxes) payable,
