                              CONTINUING GUARANTY

TO:  WELLS FARGO BANK, NATIONAL ASSOCIATION for itself and as Agent

     1.   GUARANTY; DEFINITIONS. In consideration of any credit or other 
financial accommodation heretofore, now or hereafter extended or made to SCHUFF 
INTERNATIONAL, INC., a Delaware corporation ("Borrower"), by WELLS FARGO BANK, 
NATIONAL ASSOCIATION, for itself and as agent for one or more Lenders ("Bank"), 
and for other valuable consideration, the undersigned                        ,
a                    corporation ("Guarantor"), jointly and severally   
unconditionally guarantees and promises to pay to Bank, or order, on demand in 
lawful money of the United States of America and in immediately available 
funds, any and all Indebtedness of Borrower to Bank. The term "Indebtedness" is 
used herein in its most comprehensive sense and includes any and all advances, 
debts, obligations and liabilities of Borrower, heretofore, now or hereafter 
made, incurred or created, whether voluntary or involuntary and however 
arising, whether due or not due, absolute or contingent, liquidated or 
unliquidated, determined or undetermined, and whether Borrower may be liable 
individually or jointly with others, or whether recovery upon such Indebtedness 
may be or hereafter becomes unenforceable. The term "Lenders" means those 
Lenders listed from time to time in that Credit Agreement dated as of June 30, 
1998 between Schuff Steel Company, a Delaware corporation as predecessor in 
interest to Borrower and Bank as Administrative Agent for the Lenders and as 
Arranger, Issuing Bank and Swing Line Lender.

     2.   MAXIMUM LIABILITY; SUCCESSIVE TRANSACTIONS; REVOCATION; OBLIGATION 
UNDER OTHER GUARANTIES. The liability of Guarantor shall not exceed at any one 
time the sum of FIFTEEN MILLION AND NO/100 DOLLARS ($15,000,000.00) for 
principal, plus all interest thereon and costs and expenses pertaining to the 
enforcement of this Guaranty and/or the collection of the Indebtedness of 
Borrower to Bank. Notwithstanding the foregoing, Bank may permit the 
Indebtedness of Borrower to exceed Guarantor's liability. This is a continuing 
guaranty and all rights, powers and remedies hereunder shall apply to all past, 
present and future Indebtedness of Borrower to Bank, including that arising 
under successive transactions which shall either continue the Indebtedness, 
increase or decrease it, or from time to time create new Indebtedness after all 
or any prior Indebtedness has been satisfied, and notwithstanding the death, 
incapacity, dissolution, liquidation or bankruptcy of Borrower or Guarantor or 
any other event or proceeding affecting Borrower or Guarantor. This Guaranty 
shall not apply to any new Indebtedness created after actual receipt by Bank of 
written notice of its revocation as to such new Indebtedness; provided however, 
that loans or advances made by Bank to Borrower after revocation under 
commitments existing prior to receipt by Bank of such revocation, and 
extensions, renewals or modifications, of any kind, of Indebtedness incurred by 
Borrower or committed by Bank prior to receipt by Bank of such revocation, 
shall not be considered new Indebtedness. Any such notice must be sent to Bank 
by registered U.S. mail, postage prepaid, addressed to its office at 100 West 
Washington, Phoenix, Arizona 85003, Attention: John Helms #S4101-251, or at 
such other address as Bank shall from time to time designate. Any payment by 
Guarantor shall not reduce Guarantor's maximum obligation hereunder unless 
written notice to that effect is actually received by Bank at or prior to the 
time 
<PAGE>
of such payment. The obligations of Guarantor hereunder shall be in addition to 
any obligations of Guarantor under any other guaranties of any liabilities or 
obligations of Borrower or any other person heretofore or hereafter given to 
Bank unless said other guaranties are expressly modified or revoked in writing; 
and this Guaranty shall not, unless expressly herein provided, affect or 
invalidate any such other guaranties.

     3. OBLIGATIONS JOINT AND SEVERAL; SEPARATE ACTIONS; WAIVER OF STATUTE OF 
LIMITATIONS; REINSTATEMENT OF LIABILITY. The obligations hereunder are joint and
several and independent of the obligations of Borrower, and a separate action 
or actions may be brought and prosecuted against Guarantor whether action is 
brought against Borrower or any other person, or whether Borrower or any other 
person is joined in any such action or actions. Guarantor acknowledges that 
this Guaranty is absolute and unconditional, there are no conditions precedent 
to the effectiveness of this Guaranty, and this Guaranty is in full force and 
effect and is binding on Guarantor as of the date written below, regardless of 
whether Bank obtains collateral or any guaranties from others or takes any 
other action contemplated by Guarantor. Guarantor waives the benefit of any 
statute of limitations affecting Guarantor's liability hereunder or the 
enforcement thereof, and Guarantor agrees that any payment of any Indebtedness 
or other act which shall toll any statute of limitations applicable thereto 
shall similarly operate to toll such statute of limitations applicable to 
Guarantor's liability hereunder. The liability of Guarantor hereunder shall be 
reinstated and revived and the rights of Bank shall continue if and to the 
extent for any reason any amount at any time paid on account of any 
Indebtedness guaranteed hereby is rescinded or must otherwise be restored by 
Bank, whether as a result of any proceedings in bankruptcy or reorganization or 
otherwise, all as though such amount had not been paid. The determination as to 
whether any amount so paid must be rescinded or restored shall be made by Bank 
in its sole discretion; provided however, that if Bank chooses to contest any 
such matter at the request of Guarantor, Guarantor agrees to indemnify and hold 
Bank harmless from and against all costs and expenses, including reasonable 
attorneys' fees, expended or incurred by Bank in connection therewith, 
including without limitation,in any litigation with respect thereto.

     4. AUTHORIZATIONS TO BANK. Guarantor authorizes Bank either before or 
after revocation hereof, without notice to or demand on Guarantor, and without 
affecting Guarantor's liability hereunder, from time to time to: (a) alter, 
compromise, renew, extend, accelerate or otherwise change the time for payment 
of, or otherwise change the terms of the Indebtedness or any portion thereof, 
including increase or decrease of the rate of interest thereon; (b) take and 
hold security for the payment of this Guaranty or the Indebtedness or any 
portion thereof, and exchange, enforce, waive, subordinate or release any such 
security; (c) apply such security and direct the order or manner of sale 
thereof, including without limitation, a non-judicial sale permitted by the 
terms of the controlling security agreement or deed of trust, as Bank in its 
discretion may determine; (d) release or substitute any one or more of the 
endorsers or any other guarantors of the Indebtedness, or any portion thereof, 
or any other party thereto; and (e) apply payments received by Bank from 
Borrower to any Indebtedness of Borrower to Bank, in such order as Bank shall 
determine in its sole discretion, whether or not such Indebtedness is covered 
by this Guaranty, and Guarantor hereby waives any provision of law regarding 
application of payments which specifies otherwise. Bank may without notice 
assign this Guaranty in whole or in part. Upon Bank's request, Guarantor agrees 
to provide to Bank copies of Guarantor's financial statements.





                                      -2-

<PAGE>
     5. REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to 
Bank that: (a) this Guaranty is executed at Borrower's request; (b) Guarantor 
shall not, without Bank's prior written consent, sell, lease, assign, encumber, 
hypothecate, transfer or otherwise dispose of all or a substantial or material 
part of Guarantor's assets other than in the ordinary course of Guarantor's 
business; (c) Bank has made no representation to Guarantor as to the 
creditworthiness of Borrower; and (d) Guarantor has established adequate means 
of obtaining from Borrower on a continuing basis financial and other 
information pertaining to Borrower's financial condition. Guarantor agrees to 
keep adequately informed from such means of any facts, events or circumstances 
which might in any way affect Guarantor's risks hereunder, and Guarantor 
further agrees that Bank shall have no obligation to disclose to Guarantor any 
information or material about Borrower which is acquired by Bank in any manner.

     6. GUARANTOR'S WAIVERS.

        (a) Guarantor waives any right to require Bank to: (i) proceed against 
Borrower or any other person; (ii) marshal assets or proceed against or exhaust 
any security held from Borrower or any other person; (iii) give notice of the 
terms, time and place of any public or private sale of personal property 
security held from Borrower or any other person, or otherwise comply with the 
provisions of A.R.S. section 47-9504; (iv) take any action or pursue any other 
remedy in Bank's power; or (v) make any presentment or demand for performance, 
or give any notice of nonperformance, protest, notice of protest or notice of 
dishonor hereunder or in connection with any obligations or evidences of 
indebtedness held by Bank as security for or which constitute in whole or in 
part the Indebtedness guaranteed hereunder, or in connection with the creation 
of new or additional Indebtedness.

        (b) Guarantor waives any defense to its obligations hereunder based 
upon or arising by reason of: (i) any disability or other defense of Borrower 
or any other person; (ii) the cessation or limitation from any cause 
whatsoever, other than payment in full, of the Indebtedness of Borrower or any 
other person; (iii) any lack of authority of any officer, director, partner, 
agent or any other person acting or purporting to act on behalf of Borrower, if 
a corporation, partnership or other type of entity, or any defect in the 
formation of such Borrower; (iv) the application by Borrower of the proceeds of 
any Indebtedness for purposes other than the purposes represented by Borrower 
to, or intended or understood by, Bank or Guarantor; (v) any act or omission by 
Bank which directly or indirectly results in or aids the discharge of Borrower 
or any portion of the Indebtedness by operation of law or otherwise, or which 
in any way impairs or suspends any rights or remedies of Bank against Borrower; 
(vi) any impairment of the value of any interest in any security for the 
Indebtedness or any portion thereof, including without limitation, the failure 
to obtain or maintain perfection or recordation of any interest in any such 
security, the release of any such security without substitution, and/or the 
failure to preserve the value of, or to comply with applicable law in disposing 
of, any such security; or (vii) any modification of the Indebtedness, in any 
form whatsoever, including any modification made after revocation hereof to any 
Indebtedness incurred prior to such revocation, and including without 
limitation the renewal, extension, acceleration or other change in time for 
payment of, or other change in the terms of, the Indebtedness or any portion 
thereof, including increase or decrease of the rate of interest thereon. Until 
all Indebtedness shall have been paid in full, Guarantor shall have no right of 
subrogation, and Guarantor waives any right to enforce any remedy which Bank 
now has or may hereafter have against Borrower or any other person, and waives 
any benefit of,





                                      -3-
<PAGE>
or any right to participate in, any security now or hereafter held by Bank.
Guarantor further waives all rights and defenses Guarantor may have arising out
of (A) any election of remedies by Bank, even though that election of remedies,
such as a non-judicial foreclosure with respect to any security for any portion
of the Indebtedness, destroys Guarantor's rights of subrogation or Guarantor's
rights to proceed against Borrower for reimbursement, or (B) any loss of rights
Guarantor may suffer by reason of any rights, powers or remedies of Borrower in
connection with any anti-deficiency laws or any other laws limiting, qualifying
or discharging Borrower's Indebtedness, whether by operation of law or
otherwise, including any rights Guarantor may have to a fair market value
hearing to determine the size of a deficiency following any trustee's
foreclosure sale or other disposition of any real property security for any
portion of the Indebtedness, and Guarantor waives the benefits of A.R.S.
sections 12-1566, 12-1641 et seq., 33-814,44-142 and Rule 17(F) of the Arizona 
Rules of Civil Procedure.

     7.   BANK'S RIGHTS WITH RESPECT TO GUARANTOR'S PROPERTY IN BANK'S
POSSESSION. In addition to all liens upon and rights of setoff against the
monies, securities or other property of Guarantor given to Bank by law, Bank
shall have a lien upon and a right of setoff against all monies, securities and
other property of Guarantor now or hereafter in the possession of or on deposit
with Bank, whether held in a general or special account or deposit or for
safekeeping or otherwise, and every such lien and right of setoff may be
exercised without demand upon or notice to Guarantor. No lien or right of setoff
shall be deemed to have been waived by any act or conduct on the part of Bank,
or by any neglect to exercise such right of setoff or to enforce such lien, or
by any delay in so doing, and every right of setoff and lien shall continue in
full force and effect until such right of setoff or lien is specifically waived
or released by Bank in writing.

     8.   SUBORDINATION.  Any Indebtedness of Borrower now or hereafter held by
Guarantor is hereby subordinated to the Indebtedness of Borrower to Bank. Such
Indebtedness of Borrower to Guarantor is assigned to Bank as security for this
Guaranty and the Indebtedness and, if Bank requests, shall be collected and
received by Guarantor as trustee for Bank and paid over to Bank on account of
the Indebtedness of Borrower to Bank but without reducing or affecting in any
manner the liability of Guarantor under the other provisions of this Guaranty.
Any notes or other instruments now or hereafter evidencing such Indebtedness of
Borrower to Guarantor shall be marked with a legend that the same are subject to
this Guaranty and, if Bank so requests, shall be delivered to Bank. Guarantor
will, and Bank is hereby authorized in the name of Guarantor from time to time
to, execute and file financing statements and continuation statements and
execute such other documents and take such other action as Bank deems necessary
or appropriate to perfect, preserve and enforce it rights hereunder.

     9.   REMEDIES; NO WAIVER. All rights, powers and remedies of Bank hereunder
are cumulative. No delay, failure or discontinuance of Bank in exercising any
right, power or remedy hereunder shall affect or operate as a waiver of such
right, power or remedy; nor shall any single or partial exercise of any such
right, power or remedy preclude, waive or otherwise affect any other or further
exercise thereof or the exercise of any other right, power or remedy. Any
waiver, permit, consent or approval of any kind by Bank of any breach of this
Guaranty, or any such waiver of any provisions or conditions hereof, must be in
writing and shall be effective only to the extent set forth in writing.

                                      -4-

<PAGE>
     10.  COSTS, EXPENSES AND ATTORNEYS' FEES. Guarantor shall pay to Bank 
immediately upon demand the full amount of all payments, advances, charges, 
costs and expenses, including reasonable attorneys' fees (to include outside 
counsel fees and all allocated costs of Bank's in-house counsel), expended or 
incurred by Bank in connection with the enforcement of any of Bank's rights, 
powers or remedies and/or the collection of any amounts which become due to Bank
under this Guaranty, and the prosecution or defense of any action in any way 
related to this Guaranty, whether incurred at the trial or appellate level, in 
an arbitration proceeding or otherwise, and including any of the foregoing 
incurred in connection with any bankruptcy proceeding (including without 
limitation, any adversary proceeding, contested matter or motion brought by 
Bank or any other person) relating to Guarantor or any other person or entity. 
All of the foregoing shall be paid by Guarantor with interest from the date of 
demand until paid in full at a rate per annum equal to the greater of ten 
percent (10%) or the Prime Rate in effect from time to time. The "Prime Rate" 
is a base rate that Bank from time to time establishes and which serves as the 
basis upon which effective rates of interest are calculated for those loans 
making reference thereto.

     11.  SUCCESSORS; ASSIGNMENT. This Guaranty shall be binding upon and inure 
to the benefit of the heirs, executors, administrators, legal representatives, 
successors and assigns of the parties; provided however, that Guarantor may not 
assign or transfer any of its interests or rights hereunder without Bank's 
prior written consent. Guarantor acknowledges that Bank has the right to sell, 
assign, transfer, negotiate or grant participations in all or any part of, or 
any interest in, any Indebtedness of Borrower to Bank and any obligations with 
respect thereto, including this Guaranty. In connection therewith, Bank may 
disclose all documents and information which Bank now has or hereafter acquires 
relating to Guarantor and/or this Guaranty, whether furnished by Borrower, 
Guarantor or otherwise. Guarantor further agrees that Bank may disclose such 
documents and information to Borrower.

     12.  AMENDMENT. This Guaranty may be amended or modified only in writing 
signed by Bank and Guarantor.

     13.  UNDERSTANDING WITH RESPECT TO WAIVERS; SEVERABILITY OF PROVISIONS. 
Guarantor warrants and agrees that each of the waivers set forth herein is made 
with Guarantor's full knowledge of its significance and consequences, and that 
under the circumstances, the waivers are reasonable and not contrary to public 
policy or law. If any waiver or other provision of this Guaranty shall be held 
to be prohibited by or invalid under applicable public policy or law, such 
waiver or other provision shall be ineffective only to the extent of such 
prohibition or invalidity, without invalidating the remainder of such waiver or
other provision or any remaining provisions of this Guaranty.

     14.  GOVERNING LAW. This Guaranty shall be governed by and construed in 
accordance with the laws of the State of Arizona.

     15.  ARBITRATION.

          (a)  Arbitration. Upon the demand of any party, any Dispute shall be 
resolved by binding arbitration (except as set forth in (e) below) in 
accordance with the terms of this Guaranty. A "Dispute" shall mean any action, 
dispute, claim or controversy of any kind,


                                      -5-


<PAGE>
whether in contract or tort, statutory or common law, legal or equitable, now
existing or hereafter arising under or in connection with, or in any way
pertaining to, this Guaranty and each other document, contract and instrument 
required hereby or now or hereafter delivered to Bank in connection herewith 
(collectively, the "Documents"), or any past, present or future extensions of 
credit and other activities, transactions or obligations of any kind related 
directly or indirectly to any of the Documents, including without limitation, 
any of the foregoing arising in connection with the exercise of any self-help, 
ancillary or other remedies pursuant to any of the Documents. Any party may by 
summary proceedings bring an action in court to compel arbitration of a 
Dispute. Any party who fails or refuses to submit to arbitration following a 
lawful demand by any other party shall bear all costs and expenses incurred by 
such other party in compelling arbitration of any Dispute.

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

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

          (d) Arbitrator Qualifications and Powers; Awards. Arbitrators must be 
active members of the Arizona State Bar or retired judges of the state or 
federal judiciary of Arizona, with expertise in the substantive law applicable 
to the subject matter of the Dispute. Arbitrators are empowered to resolve 
Disputes by summary rulings in response to motions filed prior to the final 
arbitration hearing. Arbitrators (i) shall resolve all Disputes in accordance 
with the substantive law of the state of Arizona, (ii) may grant any remedy or 
relief that a court of the state of Arizona could order or grant within the 
scope hereof and such ancillary relief as is necessary to make effective any 
award, and (iii) shall have the power to award recovery of all costs and fees, 
to impose sanctions and to take such other actions as they deem necessary to 
the same extent a judge could pursuant to the Federal Rules of Civil Procedure, 
the Arizona Rules of Civil Procedure or other applicable law. Any Dispute in 
which the amount in controversy is $5,000,000.00 or less shall be decided by a 
single arbitrator who shall not render an award of greater than $5,000,000.00 
(including damages, costs, fees and expenses). By submission to a


                                      -6-
<PAGE>
single arbitrator, each party expressly waives any right or claim to recover 
more than $5,000,000.00 Any Dispute in which the amount in controversy exceeds 
$5,000,000.00 shall be decided by majority vote of a panel of three 
arbitrators; provided however, that all three arbitrators must actively 
participate in all hearings and deliberations.

     (e)  Judicial Review. Notwithstanding anything herein to the contrary, in 
any arbitration in which the amount in controversy exceeds $25,000,000.00, the 
arbitrators shall be required to make specific, written findings of fact and 
conclusions of law. In such arbitrations (i) the arbitrators shall not have the 
power to make any award which is not supported by substantial evidence or which 
is based on legal error, (ii) an award shall not be binding upon the parties 
unless the findings of fact are supported by substantial evidence and the 
conclusions of law are not erroneous under the substantive law of the state of 
Arizona, and (iii) the parties shall have in addition to the grounds referred 
to in the Federal Arbitration Act for vacating, modifying or correcting an 
award the right to judicial review of (A) whether the findings of fact rendered 
by the arbitrators are supported by substantial evidence, and (B) whether the 
conclusions of law are erroneous under the substantive law of the state of 
Arizona. Judgment confirming an award in such a proceeding may be entered only 
if a court determines the award is supported by substantial evidence and not 
based on legal error under the substantive law of the state of Arizona.

     (f)  Miscellaneous. To the maximum extent practicable, the AAA, the 
arbitrators and the parties shall take all action required to conclude any 
arbitration proceeding within 180 days of the filing of the Dispute with the 
AAA. No arbitrator or other party to an arbitration proceeding may disclose the 
existence, content or results thereof, except for disclosures of information by 
a party required in the ordinary course of its business, by applicable law or 
regulation, or to the extent necessary to exercise any judicial review rights 
set forth herein. If more than one agreement for arbitration by or between the 
parties potentially applies to a Dispute, the arbitration provision most 
directly related to the Documents or the subject matter of the Dispute shall 
control. This arbitration provision shall survive termination, amendment or 
expiration of any of the Documents or any relationship between the parties.

     IN WITNESS WHEREOF, the undersigned Guarantor has executed this Guaranty 
as of ____________, 20____.

4.   REPRESENTATIONS AND WARRANTIES OF PLEDGOR

     Pledgor hereby represents and warrants that:

     4.1 If Pledgor is a corporation, partnership or trust, it (i) is duly

which it is organized; (ii) is qualified to do business and is in good standing 
under the laws of each state in which it is doing business; (iii) has full 
power and authority to own its properties and assets and to carry on its 
business as now conducted; and (iv) is fully authorized and permitted to 
execute and deliver this Agreement. The execution, delivery and performance by 
Pledgor of this Agreement and all other documents and instruments relating to 
the Obligation will not result in any breach of the terms and conditions of, 
nor constitute a default under, any agreement or instrument under which Pledgor 
is a party or is obligated. Pledgor is not in default in the performance or 
observance of any covenants, conditions or provisions of any such agreement or 
instrument.

     4.2 The address of Pledgor set forth at the beginning of this Agreement is 
the chief executive office of Pledgor (or Pledgor's residence if Pledgor is an 
individual without an office).

     4.3 The Pledged Securities are and shall be duly and validly issued and 
pledged in accordance with applicable law, and this Agreement shall not 
contravene any law, agreement or commitment binding Pledgor or the Company, and 
Pledgor shall defend the right, title, lien and security interest of Secured 
Party in and to the Pledged Securities against the claims and demands of all 
persons and other entities whatsoever.

     4.4 Pledgor has the right, power and authority to convey good and 
marketable title to the Pledged Securities; and the Pledged Securities and the 
proceeds thereof are and shall be free and clear of all claims, mortgages, 
pledges, liens, encumbrances and security interest of every nature whatsoever 
other than as imposed hereby or as set forth, if at all, on Schedule "A" 
attached hereto.

5.   IRREVOCABLE PROXY

     5.1 Pledgor irrevocably constitutes and appoints Secured Party, whether or 
not the Pledged Securities have been transferred into the name of Secured Party 
or its nominee, as Pledgor's proxy with full power, in the same manner, to the 
same extent and with the same effect as if Pledgor were to do the same, in the 
sole discretion of Secured Party:

     (a) To call a meeting of the stockholders of the Company and to vote the 
Pledged Securities, to seek the consent of such stockholders, to remove the 
directors of the Company, or any of them, and to elect new directors of the 
Company, who thereafter shall manage the affairs of the Company, operate its 
properties and carry on its business, and otherwise take any action with 
respect to the business, properties and affairs of the Company that such new 
directors shall deem necessary or appropriate, including, but not limited to, 
the maintenance, repair, renewal or alteration of any or all of the properties 
of the Company, the leasing, subleasing, sale or other disposition of any or all
of such properties, the borrowing of money on the credit of the Company 
(whether from Secured Party or others) that in the judgment of such new 
directors shall be necessary to





                                      -4-
<PAGE>
     preserve any of such properties or to discharge the obligations of the
     Company, and the employment of any or all agents, attorneys, counsel, or
     other employees as deemed by such new directors to be necessary for the
     proper operation or conduct of the business, properties and affairs of the
     Company;

          (b)  To consent to any and all actions by or with respect to the
     Company for which consent of the stockholders of the Company is or may be
     necessary or appropriate; and

          (c)  Without limitation, to do all things that Pledgor can do or could
     do as stockholder of the Company, giving Secured Party full power of
     substitution and revocation;

provided, however, that (i) the foregoing irrevocable proxy shall not be 
exercisable by Secured Party, and Pledgor alone shall have the foregoing 
powers, so long as there is no Event of Default hereunder, and (ii) this 
irrevocable proxy shall terminate at such time as this Agreement is no longer 
in full force and effect. The foregoing proxy is coupled with an interest 
sufficient in law to support an irrevocable power and shall be irrevocable and 
shall survive the death or incapacity of Pledgor. Pledgor hereby revokes any 
proxy or proxies heretofore given to any person or persons and agrees not to 
give any other proxies in derogation hereof until such time as this Agreement 
is no longer in full force and effect.

6.   COVENANTS OF PLEDGOR

     6.1 Pledgor shall not sell, transfer, assign or otherwise dispose of any 
of the Pledged Securities or any interest therein without obtaining the prior 
written consent of Secured Party and shall keep the Pledged Securities free of 
all security interests or other encumbrances except the lien and security 
interests granted herein.

     6.2 Pledgor shall pay when due all taxes, assessments, expenses and other 
charges which may be levied or assessed against the Pledged Securities.

     6.3 Pledgor shall give Secured Party immediate written notice of any 
change in Pledgor's name as set forth above and of any change in the location 
of Pledgor's chief executive office (or residence if Pledgor is an individual 
without an office).

     6.4 Pledgor, at its cost and expense, shall protect and defend the Pledged 
Securities, this Agreement and all of the rights of Secured Party hereunder 
against all claims and demands of other parties. Pledgor shall pay all claims 
and charges that in the opinion of Secured Party might prejudice, imperil or 
otherwise affect the Pledged Securities. Pledgor shall promptly notify Secured 
Party of any levy, distraint or other seizure, by legal process or otherwise, 
of all or any part of the Pledged Securities and of any threatened or filed 
claims or proceedings that might in any way affect or impair the terms of this 
Agreement.

     6.5 If Pledgor shall fail to pay any taxes, assessments, expenses or 
charges, to keep all of the Pledged Securities free from other security 
interests, encumbrances or claims, or to perform otherwise as required herein, 
Secured Party may advance the monies necessary to pay the same or to so perform.

                                      -5-


<PAGE>
     6.6  All rights, powers and remedies granted Secured Party herein, or
otherwise available to Secured Party, are for the sole benefit and protection of
Secured Party, and Secured Party may exercise any such right, power or remedy at
its option and in its sole and absolute discretion without any obligation to do
so. In addition, if, under the terms hereof, Secured Party is given two or more
alternative courses of action, Secured Party may elect any alternative or
combination of alternatives at its option and in its sole and absolute
discretion. All monies advanced by Secured Party under the terms hereof, all
amounts paid, suffered or incurred by Secured Party under the terms hereof and
all amounts paid, suffered or incurred by Secured Party in exercising any
authority granted herein, including reasonable attorneys' fees, shall be added
to the Obligation, shall be secured hereby, shall bear interest at the highest
rate payable on any of the Obligation until paid, and shall be due and payable
by Pledgor to Secured Party immediately without demand.

     6.7  Secured Party shall use such reasonable care in handling, preserving
and protecting the Pledged Securities 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 Pledged Securities
unless there is affirmative proof of a lack of due care; the lack of due care
shall not be implied solely by virtue of any loss, distribution or
disappearance. Secured Party shall not be required to take any steps necessary
to preserve any rights in the Pledged Securities against prior parties or to
protect, perfect, preserve or maintain any security interest given to secure the
Pledged Securities.

     6.8  Immediately upon demand by Secured Party, Pledgor shall execute and
deliver to Secured Party such other and additional applications, acceptances,
stock powers, authorizations, irrevocable proxies, dividend and other orders,
chattel paper, instruments or other evidences of payment and such other
documents as Secured Party may reasonably request to secure to Secured Party the
rights, powers and authorities intended to be conferred upon Secured Party by
this Agreement. All assignments and endorsements by Pledgor shall be in such
form and substance as may be satisfactory to Secured Party.

     subscription, or any other rights, privileges or options pertaining to any 
     of the Pledged Securities including, but not limited to, the right to 
     exchange, at its discretion, any or all of the Pledged Securities upon the
     merger, consolidation, reorganization, recapitalization or other 
     readjustment of the Company or upon the exercise by Pledgor or Secured 
     Party of any right, privilege or option pertaining to any of the shares of 
     the Pledged Securities, and in connection therewith to deposit and deliver 
     such shares of Pledged Securities with any committee, depository, transfer

     of the Pledged Securities; and

          (f)  Sell any or all of the Pledged Securities in accordance with the 
     provisions hereof;

but Secured Party shall have no duty to exercise any of the aforesaid rights, 
privileges or options and shall not be responsible for any failure to do so or 
delay in so doing. Pledgor waives all rights to be advised or to receive any 
notices, statements or communications received by Secured Party or its nominee 
as the record owner of all or any of the Pledged Securities. Any cash received 
and retained by Secured Party as additional collateral hereunder may be applied 
to payment in the manner provided in Subparagraph 7.3(c) below.

     7.3  In connection with Secured Party's right to sell any or all of the 
Pledged Securities, upon the occurrence of any Event of Default and at any time 
while such Event of Default is continuing:

          (a)  (i)  Secured Party shall have the right at any time and
          from time to time to sell, resell, assign and deliver, in its 
          discretion, all or any part of the Pledged Securities in one or
          more units, at the same or different times, and all right, title 
          and interest, claim and demand therein, and right of redemption
          thereof, at private sale, or at public sale to the highest bidder 
          for cash, upon credit or for future delivery, Pledgor hereby waiving 
          and releasing to the fullest extent permitted by law any and all 
          equity or right of redemption. If any of the Pledged Securities are
          sold by Secured Party upon credit or for future delivery, Secured 
          Party shall not be liable for the failure of the purchaser to 
          purchase or pay for same, and, in the event of any such failure, 
          Secured Party may resell such Pledged Securities. In no event shall
          Pledgor be credited with any part of

                                      -7-


     
<PAGE>
     the proceeds of the sale of any Pledged Securities until cash payment 
     thereof has actually been received by Secured Party.

         (ii) No demand, advertisement or notice, all of which are hereby
     expressly waived, shall be required in connection with any sale or other
     disposition of all or any part of the Pledged Securities that threatens to
     decline speedily in value or that is of a type customarily sold on a
     recognized market; otherwise Secured Party shall give Pledgor at least five
     (5) days' prior notice of the time and place of any public sale or of the
     time after which any private sale or other dispositions are to be made,
     which Pledgor agrees is reasonable, all other demands, advertisements and
     notices being hereby waived. Upon any sale, whether under this Agreement or
     by virtue of judicial proceedings, Secured Party may bid for and purchase
     any or all of the Pledged Securities and, upon compliance with the terms of
     the sale, may hold, retain, possess and dispose of such items in its own
     absolute right without further accountability, and as purchaser at such
     sale, in paying the purchase price, may turn in any note or notes held by
     Secured Party in lieu of cash up to the amount that would, upon
     distribution of the net proceeds of such sale in accordance with
     Subparagraph 7.3(c) hereof, be payable to Secured Party. In case the amount
     so payable thereon shall be less than the amount due thereon, the note or
     notes turned in (in lieu of cash) shall be returned to the holder thereof
     after being properly stamped to show the partial payment effected by such
     purchase.

     (b) Pledgor recognizes that Secured Party may be unable to effect a sale to
the public of all or a part of the Pledged Securities by reason of prohibitions
contained in applicable securities laws, but may be compelled to resort to one
or more sales to a restricted group of purchasers who will be obliged to agree,
among other things, to acquire such Pledged Securities for their own account,
for investment and not with a view to the distribution or resale thereof.
Pledgor agrees that sales so made may be at prices and other terms less
favorable to the seller than if such Pledged Securities were sold to the public,
and that Secured Party has no obligation to delay sale of any such Pledged
Securities for the period of time necessary to permit the issuer of such Pledged
Securities to register the same for sale to the public under applicable
securities laws. Pledgor agrees that negotiated sales made under the foregoing
circumstances shall be deemed to have been made in a commercially reasonable
manner.

     (c) In all sales of Pledged Securities, public or private, Secured Party
shall apply the proceeds of sale as follows:

         (i) First, to the payment of all costs and expenses, incurred hereunder
     or for the sale, transfer, or delivery, including broker's and attorneys'
     fees.

                                      -8-
<PAGE>
               (ii) Next to the payment of the Obligation; and

               (iii) The balance, if any, to Pledgor or to the person or 
          persons entitled thereto upon proper demand.

     7.4  Secured Party shall have the right, for and in the name, place and
stead of Pledgor, to execute endorsements, assignments or other instruments of
conveyance or transfer with respect to all or any of the Pledged Securities and
any instruments, documents and statements that Pledgor is obligated to furnish
or execute hereunder. Pledgor shall execute and deliver such additional
documents as may be necessary to enable Secured Party to implement such right.

     7.5  Pledgor shall pay all costs and expenses, including without limitation
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 other lien and security documents securing
the Obligation. In the event of any court proceedings, court costs and
attorneys' fees shall be set by the court and not by jury and shall be included
in any judgment obtained by Secured Party.

     7.6  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.

8.   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 right and interest granted

Obligation, to its several securities therefor in such order and manner as it
may determine.

     8.5  No modification, rescission, waiver, release or amendment of any 
provision of this Agreement shall be made except by a written agreement

effect until actual receipt by Secured Party of written notice of its revocation
as to future transactions and shall remain in full force and effect 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

otherwise affect the Collateral or the Security Interest. Debtor shall promptly 
notify Secured Party of any material levy, distraint or other seizure by legal

filed material claims or proceedings that might materially affect or impair the 
terms of this Agreement.

shall be prior to any other interests in the Collateral except any Permitted 
Liens. Debtor shall act and perform as necessary and shall execute and file all

establish and determine the validity and the continuing priority of the 
Security Interest.

     5.12      If Debtor shall fail to pay any taxes, assessments, expenses or 
charges, to keep all of the Collateral free from other security interests, 
encumbrances or claims, except any Permitted Liens to keep the Collateral in 
good condition and repair, to procure and maintain insurance thereon, or to 
perform otherwise as required herein, Secured Party may advance the monies 
necessary to pay the same, to accomplish such repairs, to procure and maintain 
such insurance or to so perform; Secured Party is hereby authorized to enter 
upon any property in the possession or control of Debtor for such purposes.

     5.13      All rights, powers and remedies granted Secured Party herein, or
otherwise available to Secured Party, are for the sole benefit and protection of
Secured Party, and Secured Party may exercise any such right, power or remedy at
its option and in its sole and absolute discretion without any obligation to do
so. In addition, if under the terms hereof, Secured Party is given two or more
alternative courses of action, Secured Party may elect any alternative or
combination of alternatives at its option and in its sole and absolute
discretion. All monies advanced by Secured Party under the terms hereof and all
amounts paid, suffered or incurred by Secured Party in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by the Security Interest, shall bear interest at
the highest rate payable on any of the Obligation until paid, and shall be due
and payable by Debtor to Secured Party immediately without demand.

     5.14      Debtor will not sign or authorize the signing on its behalf or 
the filing of any financing statement naming it as debtor covering all or any 
portion of the Collateral except as permitted by the Credit Agreement.

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

                                      -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 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

     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 
of all or any part of the Obligation, accept a renewal note therefor, reduce 
the payments thereon, release any person liable for all or any part thereof, or
otherwise change the terms of all or any part of the Obligation; (ii) hold 
other security for the payment or performance of the Obligation and enforce, 
exchange, substitute, subordinate, waive or release any such security; (iii) 
join in any extension or subordination agreement; or (iv) release any part of 
the Collateral from the Security Interest.

     9.3  Debtor waives and agrees not to assert: (i) any right to require 
Secured Party to proceed against any guarantor, to proceed against or exhaust 
any other security for the Obligation, to pursue any other remedy available to 
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 
Obligation; and (iv) any benefit of, and any right to participate in, any other 
security now or hereafter held by Secured Party.

     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 and effect 
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.

     9.8  Time is of the essence hereof. If more than one Debtor is named 
herein, the word "Debtor" shall mean all and any one or more of them, 
severally and collectively. All liability hereunder shall be joint and several. 
This Agreement shall be binding upon, and shall inure to the benefit of, the 
parties hereto and their heirs, personal representatives, successors and 
assigns.

                                      -8-
<PAGE>
The term "Secured Party" shall include not only the original Secured Party 
hereunder but also any future owner and holder, including pledgees, of note or 
notes evidencing the Obligation. The provisions hereof shall apply to the 
parties according to the context thereof and without regard to the number or 
gender of words or expressions used.

     9.9  All notices required or permitted to be given hereunder shall be in
writing and may be given in person or by United States mail, by delivery service
or by electronic transmission. Any notice directed to a party to this Agreement
shall become effective upon the earliest of the following: (i) actual receipt by
that party; (ii) delivery to the designated address of that party, addressed to
that party; or (iii) if given by certified or registered United States mail,
thirty-six (36) hours after deposit with the United States Postal Service,
postage prepaid, addressed to that party at its designated address. The
designated address of a party shall be the address of that party shown at the
beginning of this Agreement or such other address as that party, from time to
time, may specify by notice to the other parties.

     9.10 A carbon, photographic or other reproduced copy of this Agreement 
and/or any financing statement relating hereto shall be sufficient for filing 
and/or recording as a financing statement. Debtor hereby authorizes the filing 
of a financing statement with respect to the Collateral by the Secured Party.

     9.11 The capitalized terms used herein and not otherwise defined shall 
have the same meanings as set forth in the Credit Agreement.

10.  NON-DEBTOR BORROWER PROVISIONS     

     10.1 All advances of principal under the Note shall be made to Borrower 
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 
deems relevant to the risks it is assuming and hereby waives and fully 
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.

     10.2 Debtor authorizes Secured Party, 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 
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.
