6.   NOTIFICATION AND PAYMENTS; COLLECTION OF COLLATERAL; USE OF COLLATERAL
     BY DEBTOR

     6.1  Secured Party, before or after the occurrence of any Event of Default,
defined below, and without notice to Debtor, may notify any or all Obligors of
the existence of the Security Interest and may direct the Obligors to make all
payments on the Collateral to Secured Party. Until Secured Party has notified
the Obligors to remit payments directly to it, Debtor, at Debtor's own cost and
expense, shall collect or cause to be collected the accounts and monies due
under the accounts, documents, instruments and general intangibles or pursuant
to the terms of the chattel paper. Secured Party shall not be liable or
responsible for any embezzlement, conversion, negligence or default by Debtor or
Debtor's agents with respect to such collections; all agents used in such
collections shall be agents of Debtor and not agents of Secured Party. Unless
Secured Party notifies Debtor in writing that it waives one or more of the
requirements set forth in this sentence, any payments or other proceeds of
Collateral received by Debtor,

                                      -5-

<PAGE>
before or after notification to Obligors, shall be held by Debtor in trust for
Secured Party in the same form in which received, shall not be commingled with
any assets of Debtor and shall be turned over to Secured Party not later than
the next business day following the day of receipt. All payments and other
proceeds of Collateral received by Secured Party directly or from Debtor shall
be applied to the Obligation in such order and manner and at such time as
Secured Party, in its sole discretion, shall determine. In addition, Debtor
shall promptly notify Secured Party of the return to or possession by Debtor of
goods underlying any Collateral; Debtor shall hold the same in trust for Secured
Party and shall dispose of the same as Secured Party directs.

     6.2  Secured Party, before or after the occurrence of an Event of Default,
may demand, collect and sue on the Collateral (either in Debtor's or Secured
Party's name), enforce, compromise, settle or discharge the Collateral and
endorse Debtor's name on any instruments, documents, or chattel paper included
in or pertaining to the Collateral; Debtor hereby irrevocably appoints Secured
Party its attorney in fact for all such purposes.

     6.3  Until the occurrence of an Event of Default, Debtor may: (i) use,
consume and sell any inventory included in the Collateral in any lawful manner
in the ordinary course of Debtor's business provided that all sales shall be at
commercially reasonable prices; and (ii) subject to Paragraphs 6.1 and 6.2
above, retain possession of any other Collateral and use it in any lawful manner
consistent with this Agreement.

7.   COLLATERAL IN THE POSSESSION OF SECURED PARTY

     7.1  Secured Party shall use such reasonable care in handling, preserving
and protecting the Collateral in its possession as it uses in handling similar
property for its own account. Secured Party, however, shall have no liability
for the loss, destruction or disappearance of any Collateral unless there is
affirmative proof of gross negligence or a lack of due care; the lack of due
care shall not be implied solely by virtue of any loss, destruction or
disappearance.

     7.2  Debtor shall be solely responsible for taking any and all actions to
preserve rights against all Obligors; Secured Party shall not be obligated to
take any such actions whether or not the Collateral is in Secured Party's
possession. Debtor waives presentment and protest with respect to any instrument
included in the Collateral on which Debtor is in any way liable and waives
notice of any action taken by Secured Party with respect to any instrument,
document or chattel paper included in any Collateral that is in the possession
of Secured Party.

8.   EVENTS OF DEFAULT; REMEDIES

     8.1  The occurrence of any of the following events or conditions shall
constitute and is hereby defined to be an "Event of Default":

          (a)  Any failure or neglect to perform or observe any of the terms,
               provisions, or covenants of this Agreement.

          (b)  The occurrence of any event of default under the Credit
               Agreement.

                                      -6-
<PAGE>
     8.2  Secured Party, so far as may be lawful, may purchase all or any part
of the Collateral offered at any public or private sale made in the enforcement
of Secured Party's rights and remedies hereunder consistent with the Uniform
Commercial Code.

     8.3  Any demand or notice of sale, disposition or other intended action
hereunder or in connection herewith, whether required by the Uniform Commercial
Code or otherwise, shall be deemed to be commercially reasonable and effective
if such demand or notice is given to Debtor at least ten (10) days prior to such
sale, disposition or other intended action, in the manner provided herein for
the giving of notices.

     8.4  Debtor shall pay all reasonable costs and expenses, including without
limitation costs of Uniform Commercial Code searches, court costs and reasonable
attorneys' fees, incurred by Secured Party in enforcing payment and performance
of the Obligation or in exercising the rights and remedies of Secured Party
hereunder. All such costs and expenses shall be secured by this Agreement and by
all deeds of trust and other lien and security documents securing the
Obligation. In the event of any court proceedings, reasonable court costs and
reasonable attorneys' fees shall be set by the court and not by jury and shall
be included in any judgment obtained by Secured Party.

     8.5  In addition to any remedies provided herein for an Event of Default,
Secured Party shall have all the rights and remedies afforded a secured party
under the Uniform Commercial Code and all other legal and equitable remedies
allowed under applicable law. No failure on the part of Secured Party to
exercise any of its rights hereunder arising upon any Event of Default shall be
construed to prejudice its rights upon the occurrence of any other or subsequent
Event of Default. No delay on the part of Secured Party in exercising any such
rights shall be construed to preclude it from the exercise thereof at any time
while that Event of Default is continuing. Secured Party may enforce any one or
more rights or remedies hereunder successively or concurrently. By accepting
payment or performance of any of the Obligation after its due date, Secured
Party shall not thereby waive the agreement contained herein that time is of the
essence, nor shall Secured Party waive either its right to require prompt
payment or performance when due of the remainder of the Obligation or its right
to consider the failure to so pay or perform an Event of Default.

9.   MISCELLANEOUS PROVISIONS

considered a waiver of or in any way to affect or impair any other security
that Secured Party may have, acquire simultaneously herewith, or hereafter
acquire for the payment or performance of the Obligation, nor shall the taking
by Secured Party at any time of any such additional security be construed as a
waiver of or in any way to affect or impair the Security Interest; Secured Party

provision of this Agreement shall be made except by a written agreement

thereafter until all of the Obligation incurred before the receipt of such
notice, and all of the Obligation incurred thereafter under commitments

     OF COLLATERAL BY DEBTOR

Default, defined below, and without notice to Debtor, may notify any or all
Obligors of the existence of the Security Interest and may direct the Obligors
to make all payments on the Collateral to Secured Party. Until Secured Party has
notified the Obligors to remit payments directly to it, Debtor, at Debtor's own
cost and expense, shall collect or cause to be collected the accounts and monies

                                      -5-
<PAGE>

due under the accounts, documents, instruments and general intangibles or
pursuant to the terms of the chattel paper. Secured Party shall not be liable
or responsible for any embezzlement, conversion, negligence or default by
Debtor or Debtor's agents with respect to such collections; all agents used in
such collections shall be agents of Debtor and not agents of Secured Party.
Unless Secured Party notifies Debtor in writing that it waives one or more of
the requirements set forth in this sentence, any payments or other proceeds of
Collateral received by Debtor, before or after notification to Obligors, shall
be held by Debtor in trust for Secured Party in the same form in which
received, shall not be commingled with any assets of Debtor and shall be turned
over to Secured Party not later than the next business day following the day of
receipt.  All payments and other proceeds of Collateral received by Secured
Party directly or from Debtor shall be applied to the Obligation in such order
and manner and at such time as Secured Party, in its sole discretion, shall
determine. In addition, Debtor shall promptly notify Secured Party of the
return to or possession by Debtor of goods underlying any Collateral; Debtor
shall hold the same in trust for Secured Party and shall dispose of the same as
Secured Party directs.

     6.2   Secured Party, before or after the occurrence of an Event of Default,
may demand, collect and sue on the Collateral (either in Debtor's or Secured
Party's name), enforce, compromise, settle or discharge the Collateral and
endorse Debtor's name on any instruments, documents, or chattel paper included
in or pertaining to the Collateral; Debtor hereby irrevocably appoints Secured
Party its attorney in fact for all such purposes.

     6.3   Until the occurrence of an Event of Default, Debtor may: (i) use,
consume and sell any inventory included in the Collateral in any lawful manner
in the ordinary course of Debtor's business provided that all sales shall be at
commercially reasonable prices; and (ii) subject to Paragraphs 6.1 and 6.2
above, retain possession of any other Collateral and use it in any lawful
manner consistent with this Agreement.

7.   COLLATERAL IN THE POSSESSION OF SECURED PARTY

     7.1   Secured Party shall use such reasonable care in handling, preserving
and protecting the Collateral in its possession as it uses in handling similar
property for its own account. Secured Party, however, shall have no liability
for the loss, destruction or disappearance of any Collateral unless there is
affirmative proof of gross negligence or a lack of due care; the lack of due
care shall not be implied solely by virtue of any loss, destruction or
disappearance.

     7.2   Debtor shall be solely responsible for taking any and all actions to
preserve rights against all Obligors; Secured Party shall not be obligated to
take any such actions whether or not the Collateral is in Secured Party's
possession. Debtor waives presentment and protest with respect to any
instrument included in the Collateral on which Debtor is in any way liable and
waives notice of any action taken by Secured Party with respect to any
instrument, document or chattel paper included in any Collateral that is in the
possession of Secured Party.

8.   EVENTS OF DEFAULT; REMEDIES

     8.1   The occurrence of any of the following events or conditions shall
constitute and is hereby defined to be an "Event of Default":

                                      -6-

<PAGE>
           (a)  Any failure or neglect to perform or observe any of the terms,
               provisions, or covenants of this Agreement.

           (b)  The occurrence of any event of default under the Credit
               Agreement.

     8.2   Secured Party, so far as may be lawful, may purchase all or any part
of the Collateral offered at any public or private sale made in the enforcement
of Secured Party's rights and remedies hereunder consistent with the Uniform
Commercial Code.

     8.3   Any demand or notice of sale, disposition or other intended action
hereunder or in connection herewith, whether required by the Uniform Commercial
Code or otherwise, shall be deemed to be commercially reasonable and effective
if such demand or notice is given to Debtor at least ten (10) days prior to such
sale, disposition or other intended action, in the manner provided herein for
the giving of notices.

     8.4   Debtor shall pay all reasonable costs and expenses, including without
limitation costs of Uniform Commercial Code searches, court costs and reasonable
attorneys' fees, incurred by Secured Party in enforcing payment and performance
of the Obligation or in exercising the rights and remedies of Secured Party
hereunder. All such costs and expenses shall be secured by this Agreement and by
all deeds of trust and other lien and security documents securing the
Obligation. In the event of any court proceedings, reasonable court costs and
reasonable attorneys' fees shall be set by the court and not by jury and shall
be included in any judgment obtained by Secured Party.

     8.5   In addition to any remedies provided herein for an Event of Default,
Secured Party shall have all the rights and remedies afforded a secured party
under the Uniform Commercial Code and all other legal and equitable remedies
allowed under applicable law. No failure on the part of Secured Party to
exercise any of its rights hereunder arising upon any Event of Default shall be
construed to prejudice its rights upon the occurrence of any other or subsequent
Event of Default. No delay on the part of Secured Party is exercising any such
rights shall be construed to preclude it from the exercise thereof at any time
while that Event of Default is continuing. Secured Party may enforce any one or
more rights or remedies hereunder successively or concurrently. By accepting
payment or performance of any of the Obligation after its due date, Secured
Party shall not thereby waive the agreement contained herein that time is of the
essence, nor shall Secured Party waive either its right to require prompt
payment or performance when due of the remainder of the Obligation or its right
to consider the failure to so pay or perform an Event of Default.

9.   MISCELLANEOUS PROVISIONS

     9.1   The acceptance of this Agreement by Secured Party shall not be
considered a waiver of or in any way to affect or impair any other security that
Secured Party may have, acquire simultaneously herewith, or hereafter acquire
for the payment or performance of the Obligation, nor shall the taking by
Secured Party at any time of any such additional security be construed as a
waiver of or in any way to affect or impair the Security Interest; Secured Party

                                      -7-

<PAGE>
may resort, for the payment or performance of the Obligation, to its several
securities therefor in such order and manner as it may determine.

     9.2 Without notice or demand, without affecting the obligations of Debtor
hereunder or the personal liability of any person for payment or performance of
the Obligation, and without affecting the Security Interest or the priority
thereof, Secured Party, from time to time, may: (i) extend the time for payment

other security for the payment or performance of the Obligation and enforce,
exchange, substitute, subordinate, waive or release any such security; (iii)

Secured Party, or to pursue any remedy in any particular order or manner; (ii)
the benefits of any statute of limitations affecting the enforcement hereof;
(iii) demand, diligence, presentment for payment, protest and demand, and
notice of extension, dishonor, protest, demand and nonpayment, relating to the

     9.4 The terms herein shall have the meanings in and be construed under the
Uniform Commercial Code as in effect in the State of Arizona from time to time
(the "UCC"). This Agreement shall be governed by and construed according to
the laws of the State of Arizona. Each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be void or invalid, the same
shall not affect the remainder hereof which shall be effective as though the
void or invalid provision had not been contained herein.

     9.5 No modification, rescission, waiver, release or amendment of any
provision of this Agreement shall be made except by a written agreement
executed by Debtor and a duly authorized officer of Secured Party.

     9.6 This is a continuing Agreement which shall remain in full force and
effect until actual receipt by Secured Party of written notice of its
revocation as to future transactions and shall remain in full force thereafter
until all of the Obligation incurred before the receipt of such notice, and all
of the Obligation incurred thereafter under commitments extended by Secured
Party before the receipt of such notice, shall have been paid and performed in
full.

     9.7 No setoff or claim that Debtor now has or may in the future have
against Secured Party shall relieve Debtor from paying or performing the
Obligation.

subject to and in accordance with the terms thereof. If Borrower is a
corporation or partnership, it is not necessary for Secured Party to inquire
into the powers of Borrower or the officers, directors, partners or agents
acting or purporting to act on its behalf. Debtor is and shall continue to be
fully informed as to all aspects of the business affairs of Borrower that it

discharges Secured Party from any and all obligations to communicate to Debtor
any facts of any nature whatsoever regarding Borrower and Borrower's business
affairs.

affecting the obligations of Debtor hereunder or the personal liability of any
person for payment or performance of the Obligation and without affecting the
lien or the priority of the Security Interest, from time to time, at the
request of any person primarily obligated therefor, to renew, compromise,
extend, accelerate or otherwise change the time for payment or performance of,
or otherwise change the terms of, all or any part of the Obligation, including
increase or decrease any rate of interest thereon. Debtor waives and agrees not
to assert: (i) any right to require Secured Party to proceed against Borrower;
(ii) the benefits of any statutory provision limiting the liability of a
surety, including without limitation the benefit of Section 12-1641, et seq.,
of the Arizona Revised Statutes; and (iii) any defense arising by reason of any
disability or other defense of Borrower or by reason of the cessation from any
cause whatsoever of the liability of Borrower. Debtor shall have no right of
subrogation and hereby waives any right to enforce any remedy which Secured
Party now has, or may hereafter have, against Borrower.
