              Pope and Linda Pope, husband and wife ("Guarantors").


AGREEMENT:

              Borrower agrees to borrow from Lender and Lender, in reliance upon

                                    SECTION 1
                      AMOUNT AND GENERAL TERMS OF THE LOAN

              1.1    LOAN AMOUNT.

                     The amount of the Loan ("Loan Amount") shall be Eight
Million and No/100 Dollars ($8,000,000).

              1.2    INTEREST.

                     Interest ("Interest") on the unpaid balance of the Loan
shall be at a rate ("Rate") of twenty percent (20%) per annum. During any Event
of Default (as defined in this Agreement), the Rate shall be increased an
additional eight percent (8%) per annum ("Default Rate") from the date of an
Event
<PAGE>   2
of Default if Borrower does not cure an Event of Default as provided in the Note
(as defined in this Agreement). The Interest shall be calculated on the basis of
a 360 day year and 30 day month, and if not paid by the 10th day of each month
the due and unpaid Interest shall be compounded effective on the first (1st) day
of each such month.

              1.3    TERM.

                     The term ("Term") of the Loan shall be for a period of six
(6) months from the Closing (as defined in this Agreement) of the Loan.

              1.4    MULTIPLE ADVANCES.

                     The Loan will be funded in two or more advances. The first
("First Advance") shall not exceed Five Million and No/100 Dollars and the
subsequent advances ("Subsequent Advances") shall not exceed Three Million and
No/100 Dollars ($3,000,000) in the aggregate. Interest on the amount advanced
shall commence on the date of each advance. The First Advance shall be paid at
the Closing (as defined in this Agreement), and Subsequent Advances shall be
paid within three (3) days after Borrower gives Lender notice of its request for
the Subsequent Advances, but in no event shall any of the Subsequent Advances be
funded prior to April 18, 2001. At the closing of the First Advance Borrower
shall pledge 1,799,083 shares which shall be deemed sufficient to support the
full five million & NO/100 Dollar advance. At the Closing of the Subsequent
Advances, Borrower shall pledge a sufficient number of shares of the Pledged
Stock to provide a seventy five percent (75%) loan to value based upon the Bid
Price (as defined in this subsection). "Bid Price" shall be the closing bid
price on the American Stock Exchange for the Pledged Stock on the last business
day prior to the date of the First Advance and each of the Subsequent Advances.
For example, if Lender advances $900,000 to Borrower at a time when the Bid
Price is $1.00 per share, Borrower shall pledge 1,200,000 shares of the Pledged
Stock.

              1.5    PAYMENTS.

                     Interest shall be payable quarterly in arrears commencing
on the first day of the third month following the Closing, it being understood
that the first payment may include a partial month. All unpaid Interest and
principal shall be paid at the end of the Term.

              1.6    LATE CHARGE.

                     Borrower shall pay Lender a late charge of ten percent
(10%) of any payment not received by Lender within ten (10) days after said
payment is due, including the unpaid balance of the Loan at the end of the Term.

              1.7    ACCOUNT SERVICING.

                     At the Closing the Loan shall be serviced by Lender. The
costs to establish and maintain the servicing account shall be paid by Borrower,
and the costs shall be what are customarily charged for account servicing in
Maricopa County, Arizona. The following shall apply in connection with the
servicing:

                     (a) A payment shall be deemed to have been paid to Lender
              as of the date the payment is processed by Lender as long as
              Borrower's check is honored by Borrower's bank. Borrower
              acknowledges that the processing of funds by Lender shall be
              performed in the ordinary course of Lender's business and that the
              time involved in the processing may vary depending upon the
              administrative workload of Lender. Any payment received by Lender
              shall be conditionally accepted by Lender until such time as the
              processing of the payment is completed.

                     (b) Payments shall be applied in the order received by
              Lender and as provided in the Note (as defined in this Agreement).

                     (c) Borrower shall make payments to Lender as required by
              the Note and other Loan Documents without the need for a notice
              from Lender to Borrower that any payment is due.

                     (d) In addition to a statement for a full payoff of the
              unpaid balance of the Loan, Lender shall give Borrower a statement
              showing the account activity as requested by Borrower, but not
              more than two (2) times during the Term.

              5.1    EVENT OF DEFAULT

                     The existence or occurrence of any one or more of the
following events shall constitute an event of default under the Loan Documents

                     5.1.5  Bankruptcy or Insolvency.

                            Borrower being insolvent by being unable to pay
debts when due or by having liabilities in excess of assets; or Borrower

creditors, or the filing by or against Borrower of a voluntary or involuntary
petition in bankruptcy or for the appointment of a receiver (and any involuntary
petition is not dismissed within 60 days from the filing thereof); or if there
commences under any law relating to bankruptcy, insolvency, reorganization or
relief of debtors, proceedings affecting the Pledged Stock or for the
composition, extension, arrangement or adjustment of any of their respective
obligations; or if Borrower's business is discontinued as a going concern or is

other document received by or available to Borrower disclosing any such
requirement or violation of any such law or regulation, or otherwise bearing
upon Borrower's compliance thereunder. In this regard, "promptly" shall be
deemed to mean within thirty (30) days after the giving of written notification
to Borrower of the existence of such violation or notice or other document or,
where such cure or compliance cannot be fully effected within thirty (30) days,
then the commencement of the action to cure or comply within the same thirty

sufficient additional shares of Pledged Stock to provide the 75% loan to value.

              5.2    REMEDIES.

                     During an Event of Default, Lender shall have the right to
exercise any and all remedies available to it, both at law and in equity,
subject to Lender giving Borrower ten (10) days written notice for a monetary
Event of Default and thirty (30) days written notice for a non-monetary Event of
Default; provided, however, that Borrower shall have a reasonable amount of time
after the thirty (30) days for a non-monetary Event of Default, if the Event of
Default cannot be cured within thirty (30) days and Borrower commences a cure
within the thirty (30) days and diligently prosecutes the cure until it is
completed.

              6.2    SEVERABILITY.

                     In the event any provision of this Agreement is illegal,
invalid or unenforceable, such provisions shall not affect the validity of the
remainder hereof.

              6.3    STANDARD OF APPROVAL.

                     Where, within this Agreement, the approval or satisfaction
of Lender is required or permitted, or Lender's consent may be granted or

specified, Lender shall not unreasonably withhold its satisfaction, approval or
consent.

              6.4    CALCULATION OF TIME PERIODS.

                     Borrower shall not assign this Agreement. Lender shall have

                     The waiver by Lender of any breach or Event of Default by
Borrower under any of the terms of any of the Loan Documents shall not be deemed
to be a waiver of any subsequent breach or Event of Default on the part of
Borrower under the Loan Documents. The acceptance by Lender of a partial amount
of a payment due from Borrower to Lender under this Agreement shall not
constitute a waiver of the requirement of Borrower to make a full payment to
Lender and it shall not constitute a waiver by Lender of the time of the essence
provision of this Agreement.

              6.7    TIME OF THE ESSENCE.

upon the parties and their representatives, successors, and assigns.

              6.10   ATTORNEYS' FEES.

                     The other Loan Documents are not intended to supersede the
provisions of this Agreement, but shall be construed as supplemental thereto. In
the event of any inconsistency between the provisions of the other Loan
Documents and this Agreement, or in the event the provision in the other Loan

control. This Agreement shall survive the execution, recording and filing of the
Loan Documents.

              6.14   COUNTERPARTS.

                     This Agreement can be signed in counterpart.

              6.15   ENTIRE AGREEMENT.

                     This Agreement shall constitute the entire agreement of the
parties and any prior or contemporaneous verbal or written understanding or

       PAYEE:              BRIDGE FINANCIAL CORPORATION
                           an Arizona corporation
                           Attention: R. Randy Stolworthy

       ORIGINAL
       PRINCIPAL
       AMOUNT              Eight Million and No/100 Dollars ($8,000,000)
       OF LOAN:



              FOR VALUE RECEIVED, Maker promises and agrees to pay to Payee, or
order, at the mailing address of Payee, or at such other place as the holder
hereof ("Holder") may from time-to-time designate, the principal sum of Eight
Million and No/100 Dollars ($8,000,000) with Interest (as defined in this Note)
commencing as provided herein on the unpaid amount of said sum at the Base Rate
(as defined herein) or the Default Rate (as defined herein), whichever is
applicable, as follows:

              1.     MULTIPLE ADVANCES.

              The principal amount of this Promissory Note ("Note") shall be
paid by Payee to or for the benefit of Maker in multiple advances. Interest
shall commence on the date of each advance, and the advances shall be paid by
Payee to Maker pursuant to the terms and conditions of that certain Loan
Agreement dated April 3, 2001 between Maker and Payee.

              2.     INTEREST RATE.

                     a. Commencing on the date of this Note, and so long as no
Event of Default (as defined herein) exists, the unpaid balance of this Note
shall accrue interest ("Interest") at the rate of twenty percent (20%) per annum
("Base Rate").

                     b. During any Event of Default under this Note or any
security for this Note, the unpaid balance of this Note shall accrue Interest at
the rate of twenty eight percent (28%) per annum ("Default Rate"). Interest
shall accrue at the Default Rate from the date of an Event of Default, without
notice to Maker, if Borrower does not cure an Event of Default as provided in
this Note.
<PAGE>   13
                     c. The Interest provided herein shall be calculated on the
basis of a 360-day year/30-day month and if not paid as provided below by the
tenth (10th) day of each month, the due and unpaid Interest shall be compounded
effective on the first (1st) day of each such month.

              3.     PAYMENTS.

                     a. Quarterly payments of Interest only on the unpaid
principal balance of this Note at the Base Rate shall be paid on July 1, 2001
and on October 1, 2001.

                     b. If not sooner paid, all accrued and unpaid Interest and
all unpaid principal of this Note shall be paid on October 3, 2001("Maturity
Date").

              4.     LATE PAYMENT CHARGE. Maker shall pay to Holder a late
charge ("Late Payment Charge") equal to ten percent (10%) of any payment not
received by the Holder within ten (10) days after said payment is due, including
the unpaid balance of this Note as of the Maturity Date.

              5.     REASONABLENESS OF CHARGES. Maker acknowledges that upon the
occurrence of an Event of Default, the damages to the Holder would be extremely
difficult to ascertain, including the Holder's lost profit and loss of use of
the funds evidenced hereby and expenses incurred in connection with such
default, and that the accrual of Interest at the Default Rate and the Late
Payment Charge are reasonable estimates of the loss to the Holder incurred by
virtue of an Event of Default.

              6.     LEGAL LIMITS.

                     a. Maker agrees to an effective rate of interest which is
the rate stated herein plus any additional rate of interest resulting from any
other payments in the nature of interest, including without limitation, any loan
fees or other charges to the extent that such charges may be deemed includable
in interest for any purpose.

                     b. All agreements between Maker and Payee are hereby
expressly limited so that in no event whatsoever, whether by reason of deferment
in accordance with this Note or under any agreement or by virtue of acceleration
or maturity of the loan evidenced by this Note, or otherwise, shall the amount
paid or agreed to be paid to Payee for the loan, use, forbearance or detention
of the money to be loaned under this Note or to compensate Payee for damages to
be suffered by reason of a late payment or default under this Note, exceed the
maximum permissible under applicable law. If, from any circumstances whatsoever,
fulfillment of any provision of this Note, or of any provision in the security
for this Note at the time performance of such provision shall be due, shall
involve exceeding the limit of validity prescribed by law, from the date of this
Note, the obligations to be fulfilled shall be reduced to the limit of such
validity. This provision shall never be superseded or waived and shall control
every other provision of all agreements between Maker and Payee.

              7.     PREPAYMENT. The unpaid principal balance of this Note may
be prepaid in whole or in part without penalty at any time upon five (5) days
prior written notice to the Holder.

              8.     FORM OF PAYMENTS. Principal and Interest shall be payable
in lawful money of the United States of America in immediately available funds.

              9.     CREDITING OF PAYMENTS. Each payment hereunder shall be
credited first to accrued Interest and then to principal.

              10.    EVENTS OF DEFAULT AND REMEDIES.
<PAGE>   14
                     a. The existence or occurrence of either one or both of the
following events shall constitute an event of default ("Event of Default") under
this Note: (i) The failure by Maker to make any payment of principal, Interest,
Late Payment Charge or any other cost or expense due under this Note in
accordance with the terms of this Note; or, (ii) The occurrence of any event of
default under any security for this Note, including the Pledge (as defined
herein).

                     b. Upon the occurrence of any Event of Default and the
failure of Maker to cure such default within ten (10) days after notice thereof
if monetary and within thirty (30) days after notice thereof if non-monetary
(unless the Event of Default cannot be cured within thirty (30) days and Maker
commences a cure within the thirty (30) days and diligently prosecutes the cure
until it is complete, in which event, Maker shall have a reasonable amount of
time after the thirty (30) days to cure a non-monetary default): (i) the entire
unpaid principal balance, any unpaid Interest, and any other amounts owing under
this Note shall, at the option of the Holder and without further notice or
demand of any kind to Maker or any other person, immediately become due and
payable; and, (ii) the Holder shall have and may exercise any and all rights and
remedies available at law or in equity and also any and all rights and remedies
provided in any security for this Note.

                     c. The remedies of the Holder, as provided in this Note and
in any security for this Note, shall be cumulative and concurrent, and may be
pursued singularly, successively or together, at the sole discretion of the
Holder, and may be exercised as often as occasion therefor shall arise. No act
of omission or commission of the Holder, including specifically any failure to
exercise any right, remedy or recourse, shall be deemed to be a waiver or
release of any right, remedy or recourse, such waiver or release to be effected
only through a written document executed by the Holder. A waiver or release with
reference to any one event shall not be construed as continuing, as a bar to, or
as a waiver or release of, any subsequent right, remedy or recourse as to a
subsequent event.

              11.    SECURITY. This Note is secured by, among other things, and
is entitled to the benefits of, a stock pledge and security agreement ("Pledge")
dated the date of this Note. The provisions of the Pledge are incorporated
herein by reference as if set forth in full, and the covenants and conditions of
this Note shall control if there is a conflict between them and the covenants
and conditions contained in the Pledge.

              12.    ATTORNEYS' FEES. In the Event of Default under this Note or
in the event the Holder seeks legal advice in order to enforce the provisions of
this Note after an Event of Default, Maker agrees to pay a reasonable sum to
Holder for Holder's attorneys' fees. If any action is brought to enforce or
interpret the provisions of this Note, the prevailing party shall be entitled to
a reasonable sum for attorneys' fees.

              13.    GOVERNING LAW AND SEVERABILITY. This Note is made pursuant
to, and shall be construed, governed and enforced under the laws of the State of
Arizona. If any provision of this Note or any security for this Note is
construed or interpreted by a court of competent jurisdiction to be void,
invalid or unenforceable, such decision shall affect only those provisions so
construed or interpreted and shall not affect the remaining provisions of this
Note or any security for this Note.

              14.    TIME OF ESSENCE. Time is of the essence of this Note.

              15.    PAYMENT WITHOUT OFFSET. Principal and Interest shall be
paid without deduction or offset.

              16.    CALENDAR DAYS. Unless otherwise provided in this Note to
the contrary, calendar days, and not business days, shall be used in calculating
any time periods set forth in this Note.

              17.    NOTICES. Any notices which any party may be required, or
may desire, to give, unless otherwise specified, shall be in writing and shall
be (i) hand-delivered, effective upon receipt,
<PAGE>   15
(ii) transmitted by telecopier, effective upon receipt, with the original mailed
the same date by first class mail, postage prepaid, (iii) sent by United States
Express Mail or by private overnight courier, effective upon receipt, or (iv)
served by certified mail, postage prepaid, return receipt requested and
addressed to such party at the address set forth above, or to such other
address(es) or addressee(s) as the party to be served with notice may have
furnished in writing to the other party, effective three (3) days after mailing.

              18.    ASSIGNMENT. Payee or any other Holder of this Note may
assign all or a portion of its rights, title and interest in this Note and
security to any person, firm, corporation or other entity without the consent of
Maker.

              19.    RELATIONSHIP. The relationship of the parties hereto is
that of borrower and lender and it is expressly understood and agreed that
nothing contained in this Note or in any security for this Note shall be
interpreted or construed to make Maker and Payee partners, joint venturers or
participants in any other legal relationship except for borrower and lender.

              20.    WAIVER. Except as otherwise expressly provided to the
contrary in this Note, the Pledge or other loan documents relating to this Note,
Maker for itself and for its successors, transferees and assigns and all
guarantors, endorsers and signers, hereby waives all valuation and appraisement
privileges, presentment and demand for payment, protest, notice of protest and
nonpayment, dishonor and notice of dishonor, bringing of suit, lack of diligence
or delays in collection or enforcement of this Note and notice of the intention
to accelerate, the release of any party liable, the release of any security for
this Note, the taking of any additional security and any other indulgence or
forbearance. Maker agrees that this Note and any or all payments coming due
hereunder may be extended or renewed from time to time without in any way
affecting or diminishing Maker's liability under this Note. The acceptance by
Holder of a partial amount of a payment due from Maker to Holder under this Note
shall not constitute a waiver of the requirement of Maker to make a full payment
to Holder, and it shall not constitute a waiver by Holder of the time of the
essence provision of this Note.

              21.    HEADINGS. The subject headings of the paragraphs of this
Note are included for purposes of convenience only, and shall not affect the
construction or interpretation of any of its provisions.

              IN WITNESS WHEREOF, Maker has executed this Note as of the date
set forth above.

                           husband and wife

       LENDER:             BRIDGE FINANCIAL CORPORATION
                           an Arizona corporation
                           Attention: R. Randy Stolworthy

       BORROWER:           SUN NZ, LLC
                           an Arizona limited liability company
                           Attention: William Pope
                           2525 East Camelback Road, Suite 888
                           Phoenix, Arizona 85016
                           Facsimile Number (602) 852-5599


       ORIGINAL
       PRINCIPAL           Eight Million and No/100 Dollars ($8,000,000)
       AMOUNT OF           evidenced by that  certain Promissory Note of even
       INDEBTEDNESS        date herewith between Lender, as Payee, and Borrower,
       GUARANTEED:         as Maker (the "Note")



              FOR VALUABLE CONSIDERATION, Guarantor unconditionally guarantees
and promises to pay to Lender, or order, on demand, in lawful money of the
United States, any and all obligations of Borrower to Lender, under and by
virtue of the Note and the other loan documents related to the Note.

              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 regardless of whether an action is brought
against Borrower or whether Borrower is joined in any such action or actions;
and Guarantor waives the benefit of any statute of limitations affecting its
liability hereunder or the enforcement thereof. Each Guarantor expressly agrees
that recourse may be made against the marital community and the separate
property of each Guarantor and in such order and manner as Lender may elect. The
provisions of any law or regulation are waived to the extent they require
spouses to be sued jointly for satisfaction of any debt or obligation first from
community property and second from sole and separate property.

              Guarantor authorizes Lender, without notice or demand and without
affecting its liability hereunder, from time to time to (a) renew, compromise,
extend, accelerate or otherwise change the time for payment of or the terms of
the Note or any part thereof, increase the amount or the rate of interest of the
Note, or shorten the term of the Note; (b) take and hold security for the
payment of this Guaranty of the obligations guaranteed, and exchange, enforce,
waive and release any such security; (c) apply such security and direct the
order or manner of sale thereof as Lender in its discretion may determine; and
(d) release or substitute any one or more of the endorsers of Guarantor. Lender
may without notice assign this Guaranty in whole or in part.
<PAGE>   18
              Guarantor waives any right to require Lender to (a) proceed
against Borrower; (b) proceed against or exhaust any security held from
Borrower; or (c) pursue any other remedy in Lender's power whatsoever, and any
laws or regulations to the contrary are hereby waived. Guarantor waives 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.

              Guarantor also waives (a) all diligence in collection or
protection of or realization on the Note, on any obligation under the Guaranty
or on any security for the Note; (b) any and all suretyship defenses and
defenses in the nature thereof; (c) any rights for a homestead exemption; and
(d) any defenses based upon release of collateral, failure to perfect a lien on
the collateral, failure to maintain a lien on the collateral, the release of
Borrower, the modification of the Note without Guarantor's consent or notice of
Lender's acceptance of this Guaranty.

              Until all obligations of Borrower to Lender under the Note shall
have been paid in full, Guarantor shall have no right of subrogation, and waive
any right to enforce any remedy which Lender now has or may hereafter have
against Borrower, and waive any benefit of and any right to participate in any
security now or hereafter held by Lender. Guarantor waives all presentments,
demands for performance, notice of nonperformance, protests, notices of protest,
notices of dishonor, and notices of acceptance of this Guaranty and of the
existence, creation or incurring of new or additional obligations.

              No delay on the part of Lender in the exercise of any right or
remedy shall operate as a waiver thereof, and no single or partial exercise by
Lender of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy; nor shall any modification or
waiver of any of the provisions of this Guaranty be binding on Lender except as
expressly set forth in writing, duly signed and delivered on behalf of Lender.
No action of Lender permitted hereunder shall in any way affect or impair the
rights of Lender and the obligations of Guarantor under this Guaranty.

              Guarantor represents and warrants to Lender that:

              (a) The execution, delivery and performance by Guarantor of this
Guaranty does not and will not conflict with or contravene any law, rule,
regulation, judgment, order or decree of any government, governmental
instrumentality or court having jurisdiction over Guarantor or Guarantor's
activities or properties or conflict with, or result in any default under any
agreement or instrument of any kind to which Guarantor is a party or by which
Guarantor or Guarantor's properties may be bound or affected;

              (b) Neither the execution and delivery by Guarantor of this
Guaranty nor the performance by Guarantor hereunder require the consent,
approval, order or authorization of, or registration with, or the giving of
notice to any governmental authority, domestic or foreign;

              (c) This Guaranty has been duly executed and delivered by
Guarantor and constitutes a legal, valid and binding obligation of Guarantor
enforceable against Guarantor in accordance with its terms;

              (d) There is no action, litigation or other proceeding pending or,
to Guarantor's best knowledge, threatened against Guarantor before any court,
arbitrator or administrative agency which may have an adverse effect on
Guarantor's assets, businesses, or financial condition or which would prevent,
hinder or jeopardize Guarantor's performance under this Guaranty.

              (e) Guarantor is fully familiar with all of the covenants, terms
and conditions of the Note and related documents and have reviewed such
documents personally and with counsel;

              (f) The financial statements (including the notes thereto) and
other financial information of any person or entity provided to Lender in
support of Guarantor's application for the Loan are materially true, correct and
complete, and present fairly the financial condition and the results of
operations of the persons set forth in such financial statements in accordance
with generally accepted accounting principles. There have not been any material
adverse changes in the
<PAGE>   19
condition, affairs or prospects, financial or otherwise, of any person or
company whose financial condition is reflected in any of the aforesaid financial
statements since the date of such financial statements; and Guarantor is unaware
of any facts or circumstances which might give rise to any such material adverse
change. In the event Guarantor becomes aware of any such material change, either
before or after any disbursement by Lender, Guarantor shall notify Lender in
writing immediately after Guarantor becomes aware of such facts or
circumstances.

              (g) Except as may be set forth in the written financial statements
presented by Guarantor to Lender, Guarantor is not a party to any contract,
agreement, indenture or instrument or subject to any restriction which
individually or in the aggregate require any obligations of Guarantor to be
performed as of the date hereof or as a result of executing this Guaranty, which
might adversely affect Guarantor's financial condition or businesses, or which
would in any way jeopardize the ability of Guarantor to perform hereunder; and

              (h) Guarantor was not induced to give this Guaranty by the fact
that there are or may be other guarantors either to this Guaranty or otherwise.
It is understood that this Guaranty is not being given in consideration of any
such other guaranty, and, in this regard, Lender may, at its discretion, take,
receive, accept, sue upon, release or compromise any such other guaranty of the
Note obtained or which may be obtained from any other person or entity, without
affecting this Guaranty or impairing any rights which Lender may have under this
Guaranty.

              Any provision of this Guaranty which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and no such prohibition or unenforceability shall
invalidate or render unenforceable such provision in any other jurisdiction.

              Any property assigned, pledged or hypothecated as security for
this Guaranty shall be deemed to secure all obligations of Borrower to Lender to
the same extent as if the same were Borrower's property and given as security by
Borrowers therefor.

              Any obligations of Borrower now or hereafter held by or payable to
Guarantor are hereby subordinated to the obligations of Borrower to Lender; and
such obligations of Borrower to Guarantor if Lender so requests shall be
collected, enforced and received by Guarantor as trustees for Lender and be paid
over to Lender on account of the obligations of Borrower to Lender but without
reducing or affecting in any manner the liability of Guarantor under the other
provisions of this Guaranty. Unless and until there is an Event of Default under
the Note and other loan documents related to the Note, Guarantor shall have the
right to receive payments under the obligations of Borrower to Guarantor in the
ordinary course of business.

              Where the Borrower is an entity, it is not necessary for Lender to
inquire into the powers of Borrower or the officers, directors, partners,
members or agents acting or purporting to act on its behalf, and any obligations
made or created in reliance upon the professed exercise of such powers shall be
guaranteed hereunder.

              Guarantor agrees to pay a reasonable attorneys' fee and all other
costs and expenses which may be incurred by Lender in the enforcement of this
Guaranty.

              In all cases where there is more than one Guarantor, then all
words used herein in the singular shall be deemed to have been used in the
plural where the context and construction so require.
<PAGE>   20
              If this Guaranty requires more than one signature, this Guaranty
may be signed in counterpart and, together, the counterpart Guaranties shall
constitute a single Guaranty.

              This Guaranty shall remain in full force and effect until the
expiration of any time periods within which a bankruptcy court can order the
disgorgement of payments made by Borrower to Lender under the Note or related
documents.

              This Guaranty is made pursuant to, and shall be construed,
governed and enforced under the laws of the State of Arizona.

              IN WITNESS WHEREOF, the undersigned Guarantor has executed this
Guaranty as of the date set forth above.

                                        GUARANTOR:

Bridge Financial Corporation
333 N. 44th St., Suite 420
Phoenix, AZ 85008-6568


Ladies and Gentlemen:

         I am legal counsel for SUN NZ, LLC, an Arizona limited liability
company ("Borrower") and Sun NMA, Inc., an Arizona corporation, the managing
member of the Borrower ("Managing Member"). As such counsel, I have examined
originals (or copies identified to my satisfaction as true copies of the
originals) of the following documents dated April 3, 2001 ("Documents"):

         1.       Loan Agreement;

         2.       Promissory Note;

         3.       Unconditional Guaranty;

         4.       Stock Certificate Assignment;

         5.       Stock Pledge and Security Agreement ("Pledge");

         6.       Uniform Commercial Code Financing Statement ("Financing
                  Statement"); and

         7.       Transfer Agent Letter.

I have also examined the Articles of Organization, Operating Agreement, Articles
of Incorporation, Bylaws and other relevant organizational documents of the
Borrower and Managing Member.

         In my examination, I have assumed the genuineness of all signatures and
the authenticity of the Documents submitted to me as originals conforming to the
originals of the Documents submitted to me as copies.

         I am an attorney licensed to practice in the State of Arizona, and
accordingly, I do not express any opinion as to the laws or their effect in any
jurisdiction other than the State of Arizona.

         The enforceability of the Documents and the rights and remedies of the
parties thereunder, are subject to, and limited by: (1) bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws now or
hereafter in effect relating to creditors' rights generally; (2) availability of
equitable remedies; and (3) future changes or interpretations to current laws,
rules and regulations of the State of Arizona.

         Based upon and subject to the foregoing, it is my opinion that:

         1. The Borrower is a limited liability company duly organized, validly
existing and in good standing under the laws of the State of Arizona.

         2. The Managing Member is a corporation duly organized, validly
existing and in good standing under the laws of the State of Arizona.

         3. The Borrower and Managing Member have all the requisite power and
authority to execute and deliver the Documents, and the Borrower has all of the
requisite power and authority to perform under the Documents.
<PAGE>   36
         4. Upon execution and delivery of the Documents, the Documents shall be
binding obligations of and enforceable against the Borrower according to their
terms.

         5. To my knowledge, the execution, delivery and performance under the
Documents by Borrower do not violate the laws and regulations applicable to the
Borrower and Managing Member.

         6. To my knowledge, there is not any action, suit or proceeding, at law
or in equity, either pending or threatened against the Borrower that would
materially and adversely affect the ability of the Borrower to perform under the
Documents.

The words "my knowledge" mean the actual knowledge of John E. Olson as of the
date of this letter without any independent investigation or inquiry to
determine if my actual knowledge is true and correct.

         In rendering this opinion, I have relied upon the fact that the Pledge
and Financing Statement will be properly recorded and filed for perfection of
the liens created thereby.

         I have no information concerning and express no opinion on the priority
of the security interest which will be perfected by the filing of the Financing
Statement. However, to my knowledge, the Pledged Stock for the First Advance is
not subject to any pledge and, at the time of each Subsequent Advance, the
Pledged Stock for each Subsequent Advance shall not be subject to any pledge
other than the ones created by each Pledge.

         This letter is limited to the above and is furnished by me as legal
counsel for the Borrower and Managing Member to you solely for your benefit and
with respect to the Documents.

                                               Sincerely,



                                               --------------------------------
