facilities exceed the sum so permitted, Borrower shall immediately repay to Bank
such excess.

This Alternative Dispute Resolution Agreement ("Agreement") is made and entered
into as of the 3rd day of April 1997, by and between the undersigned ("Obligor")
and Union Bank of California, N.A., ("Bank") (Obligor and Bank herein
collectively, the "Parties" and individually, a "Party"). Initially capitalized
terms used in this Agreement which are not otherwise defined herein shall have
the respective meanings set forth in Paragraph 7 of this Agreement.

1.  CLAIMS SUBJECT TO ARBITRATION OR JUDICIAL REFERENCE.

    (a) Any Claim other than a Claim that arises out of or relates to any
        obligation under any Subject Document that is secured, in whole or in
        part, by an interest in real property shall, at the written request of
        any Party, be determined by Arbitration.

    (b) Any Claim that arises out of or relates to any obligation under any
        Subject Document that is secured, in whole or in part, by an interest in
        real property shall be determined by Arbitration only with the consent
        of both Parties. If both Parties do not consent to the determination of
        any such Claim by Arbitration, then such Claim shall, at the written
        request of any Party, be determined by Reference.

    (c) The determination as to whether or not a Claim arises out of or relates
        to any obligation under any Subject Document that is secured, in whole
        or in part, by an interest in real property shall be made at the time
        the arbitrator or referee is selected pursuant to Paragraph 2 of this
        Agreement.

2. SELECTION OF ARBITRATOR OR REFEREE. Within 30 days after written demand, or
within 30 days after commencement by any Party, of any lawsuit subject to this
Agreement, the Parties shall select a single neutral arbitrator pursuant to the
Commercial Arbitration Rules of the AAA or a single neutral referee pursuant to
the Judicial Reference Procedures of the AAA. However, the arbitrator or referee
selected must be a retired state or federal court judge with at least five years
of judicial experience in civil matters. In the event that the selection
pursuant to such Commercial Arbitration Rules or Judicial Reference Procedures
does not result in the appointment of a single neutral arbitrator or a single
neutral referee within 30 days, any such Party may petition the court to appoint
a single neutral arbitrator or single neutral referee with the judicial
experience described above. The Parties shall equally bear the fees and expenses
of the arbitrator or referee unless the arbitrator or referee otherwise provides
in the award or statement of decision.

3.  CONDUCT OF ARBITRATION OR REFERENCE.

    (a) Except as provided in this Agreement, the arbitrator shall have the
        powers provided under Applicable State Law and the Commercial
        Arbitration Rules of the AAA, and the referee shall have the powers
        provided under Applicable State Law and the Judicial Reference
        Procedures of the AAA.

    (b) The arbitrator or referee shall determine all challenges to the legality
        or enforceability of this Agreement.

    (c) The arbitrator or referee shall apply the rules of evidence to the same
        extent as they would be applied in a court of law.

    (d) A Party may not conduct discovery unless the arbitrator or referee
        grants such Party leave to do so upon a showing of good cause. All
        discovery shall be completed within 90 days after the appointment of the
        arbitrator or referee, except upon a showing of good cause by any Party.
        The arbitrator or referee shall limit discovery to non-privileged
        material that is relevant to the issues to be determined by the
        arbitrator or referee.

    (e) The arbitrator or referee shall determine the time of the hearing and
        shall designate its location based upon the convenience of the
        arbitrator or referee, the Parties and any witnesses. However, such
        hearing shall be commenced within 30 days after completion of discovery,
        unless the arbitrator or referee grants a continuance upon a showing of
        good cause by any Party. At least 7 days before the date set for such
        hearing, the Parties shall exchange copies of exhibits to be offered as
        evidence, and lists of the witnesses who will testify, at such hearing.
        Once commenced, the hearing shall proceed day to day until completed,
        unless the arbitrator or referee grants a continuance upon a showing of
        good cause by any Party. Any Party may cause to be prepared, at its
        expense, a written transcription or electronic recordation of such
        hearing.

    (f) Subject to the provisions of this Agreement, the arbitrator may award,
        or the referee may report, a statement of decision providing for any
        remedy or relief, including without limitation judicial foreclosure,
        deficiency judgment and equitable relief, and give effect to all legal
        and equitable defenses, including without limitation, statutes of
        limitation, the statute of frauds, waiver and estoppel.

    (g) The award of the arbitrator or the statement of decision of the referee
        shall be supported by written findings of fact and conclusions of law
        delivered by the arbitrator or referee to the Parties concurrently with
        such award or statement of decision.

    (h) In the event that punitive damages are permitted under Applicable State
        Law, the award of the arbitrator or the statement of decision of the
        referee may provide for recovery of punitive damages provided that the
        arbitrator or referee first makes written findings of fact that would
        satisfy the requirements for recovery of punitive damages under
        Applicable State Law. Any such punitive damages shall not exceed a sum
        equal to three times the amount of actual damages as determined by the
        arbitrator or referee.

    (i) The arbitrator shall have the power to award or the referee shall have
        the power to report a statement of decision providing for reasonable
        attorneys' fees (including a reasonable allocation for the costs of
        in-house counsel) and costs to the prevailing party.

    (j) In the event that Applicable State Law provides that publications or
        communications made in a judicial proceeding are subject to a litigation
        privilege, such litigation privilege shall apply to the same extent to
        publications or communications made in the Arbitration or Reference.

4.  PROVISIONAL REMEDIES, SELF-HELP AND FORECLOSURE. No provision of this
Agreement shall limit the right of any Party (a) to exercise self-help remedies
including, without limitation, set-off, (b) to foreclose against or sell any
collateral, by power of sale or otherwise or (c) to obtain or oppose provisional
or ancillary remedies from a court of competent jurisdiction before, after or
during the pendency of the Arbitration or Reference. The exercise of, or
opposition to, any such remedy does not waive the right of any Party to
Arbitration or Reference pursuant to this Agreement.

5.  FINAL, BINDING AND NONAPPEALABLE JUDGMENT. Any court of competent
jurisdiction shall, upon the petition of any Party, confirm the award of the
arbitrator and enter judgment in conformity therewith. Any court of competent
jurisdiction shall, upon the filing of the statement of decision of the referee,
enter judgment thereon. Any such judgment shall be final, binding and
nonappealable.

6.  MISCELLANEOUS. In the event that multiple claims are asserted, some of
which are found not subject to this Agreement, the Parties agree to stay the
proceedings of the claims not subject to this Agreement until all other claims
are resolved in accordance with this Agreement. In the event that claims are
asserted against multiple parties, some of whom are not subject to this
Agreement, the Parties



   13

agree to sever the claims subject to this Agreement and resolve them in
accordance with this Agreement. In the event that any provision of this
Agreement is found to be illegal or unenforceable, the remainder of this
Agreement shall remain in full force and effect. In the event of any challenge
to the legality or enforceability of this Agreement, the prevailing Party shall
be entitled to recover the costs and expenses, including reasonable attorneys'
fees, incurred by it in connection therewith. Applicable State Law shall govern
the interpretation of this Agreement. This Agreement fully states all of the
terms and conditions of the Parties' agreement regarding the matters mentioned
in, or incidental to, this Agreement. This Agreement supersedes all oral
negotiations and prior writings concerning the subject matter hereof.

        set-off, (ii) to foreclose against or sell any collateral, by power of
        sale or otherwise or (iii) to obtain or oppose provisional or ancillary
        remedies from a court of competent jurisdiction before, after or during

=================================================================================================================================



SAN DIEGO, CALIFORNIA               $6,000,000.00                Date__________

FOR VALUE RECEIVED, on September 15, 1998, the undersigned ("Debtor") promises
to pay to the order of Union Bank of California, N.A. ("Bank"), as indicated
below, the principal sum of SIX MILLION AND NO/100 Dollars ($6,000,000.00), or
so much thereof as is disbursed, together with interest on the balance of such
principal from time to time outstanding, at the per annum rate or rates and at
the times set forth below.

1. INTEREST PAYMENTS. Debtor shall pay interest on the Fifteenth day of each
month (commencing May 15, 1997). Should interest not be paid when due, it shall
become part of the principal and bear interest as herein provided. All
computations of interest under this note shall be made on the basis of a year of
360 days, for actual days elapsed.

     a. BASE INTEREST RATE. At Debtor's option, amounts outstanding hereunder in
     increments of at least $10,000 shall bear interest at a rate, based on an
     index selected by Debtor, which is 1.75% per annum in excess of Bank's
     LIBOR-Rate for the Interest Period selected by Debtor.

     Any Base Interest Rate may not be changed, altered or otherwise modified
     until the expiration of the Interest Period selected by Debtor. The
     exercise of interest rate options by Debtor shall be as recorded in Bank's
     records, which records shall be prima facie evidence of the amount borrowed
     under either interest option and the interest rate; provided, however, that
     failure of Bank to make any such notation in its records shall not
     discharge Debtor from its obligations to repay in full with interest all
     amounts borrowed. In no event shall any Interest Period extend beyond the
     maturity date of this note.

     To exercise this option, Debtor may, from time to time with respect to
     principal outstanding on which a Base Interest Rate is not accruing, and on
     the expiration of any Interest Period with respect to principal outstanding
     on which a Base Interest Rate has been accruing, select an index offered by
     Bank for a Base Interest Rate Loan and an Interest Period by telephoning an
     authorized lending officer of Bank located at the banking office identified
     below prior to 10:00 a.m., Pacific time, on any Business Day and advising
     that officer of the selected index, the Interest Period and the Origination
     Date selected (which Origination Date, for a Base Interest Rate Loan based
     on the LIBOR-Rate, shall follow the date of such selection by no more than
     two (2) Business Days).

     Bank will mail a written confirmation of the terms of the selection to
     Debtor promptly after the selection is made. Failure to send such
     confirmation shall not affect Bank's rights to collect interest at the rate
     selected. If, on the date of the selection, the index selected is
     unavailable for any reason, the selection shall be void. Bank reserves the
     right to fund the principal from any source of funds notwithstanding any
     Base Interest Rate selected by Debtor.

     b. VARIABLE INTEREST RATE. All principal outstanding hereunder which is not
     bearing interest at a Base Interest Rate shall bear interest at a rate per
     annum equal to the Reference Rate, which rate shall vary as and when the
     Reference Rate changes.



                                      -1-

   17

At any time prior to the maturity of this note, subject to the provisions of
paragraph 4. below, of this note, Debtor may borrow, repay and reborrow hereon
so long as the total outstanding at any one time does not exceed the principal
amount of this note. Debtor shall pay all amounts due under this note in lawful
money of the United States at Bank's SAN DIEGO COMMERCIAL BANKING Office, or
such other office as may be designated by Bank, from time to time.

2. LATE PAYMENTS. If any payment required by the terms of this note shall remain
unpaid ten days after same is due, at the option of Bank, Debtor shall pay a fee
of $100 to Bank.

3. INTEREST RATE FOLLOWING DEFAULT. In the event of default, at the option of
Bank, and, to the extent permitted by law, interest shall be payable on the
outstanding principal under this note at a per annum rate equal to five percent
(5%) in excess of the interest rate specified in paragraph 1.b, above,
calculated from the date of default until all amounts payable under this note
are paid in full.

4. PREPAYMENT.

     a. Amounts outstanding under this note bearing interest at a rate based on
     the Reference Rate may be prepaid in whole or in part at any time, without
     penalty or premium. Amounts outstanding under this note bearing interest at
     a Base Interest Rate may only be prepaid, in whole or in part provided Bank
     has received not less than five (5) Business Days prior written notice of
     an intention to make such prepayment and Debtor pays a prepayment fee to
     Bank in an amount equal to the present value of the product of: (i) the
     difference (but not less then zero) between (a) the Base Interest Rate
     applicable to the principal amount which Debtor intends to prepay, and (b)
     the return which Bank could obtain if it used the amount of such prepayment
     of principal to purchase at bid price regularly quoted securities issued by
     the United States having a maturity date most closely coinciding with the
     relevant Base Rate Maturity Date and such securities were held by Bank
     until the relevant Base Rate Maturity Date ("Yield Rate"); (ii) a fraction,
     the numerator of which is the number of days in the period between the date
     of prepayment and the relevant Base Rate Maturity Date and the denominator
     of which is 360; and (iii) the amount of the principal so prepaid (except
     in the event that principal payments are required and have been made as
     scheduled under the terms of the Base Interest Rate Loan being prepaid,
     then an amount equal to the lesser of (A) the amount prepaid or (B) 50% of
     the sum of (1) the amount prepaid and (2) the amount of principal scheduled
     under the terms of the Base Interest Rate Loan being prepaid to be
     outstanding at the relevant Base Rate Maturity Date). Present value under
     this note is determined by discounting the above product to present value
     using the Yield Rate as the annual discount factor.

     b. In no event shall Bank be obligated to make any payment or refund to
     Debtor, nor shall Debtor be entitled to any setoff or other claim against
     Bank, should the return which Bank could obtain under the above prepayment
     formula exceed the interest that Bank would have received if no prepayment
     had occurred. All prepayments shall include payment of accrued interest on
     the principal amount so prepaid and shall be applied to payment of interest
     before application to principal. A determination by Bank as to the
     prepayment fee amount, if any, shall be conclusive.

     c. Such prepayment fee, if any, shall also be payable if prepayment occurs
     as the result of the acceleration of the principal of this note by Bank
     because of any default hereunder. If, following such acceleration, all or
     any portion of a Base Interest Rate Loan is satisfied, whether through sale
     of property encumbered by any security agreement or other agreement
     securing this note, at a foreclosure sale held thereunder or through the
     tender of payment at any time following such acceleration, but prior to
     such a foreclosure sale, then such satisfaction shall be deemed an evasion
     of the prepayment conditions set forth above, and Bank shall, automatically
     and without notice or demand, be entitled to receive, concurrently with
     such satisfaction the prepayment fee set forth above, and the amount of
     such prepayment fee shall be added to the principal. DEBTOR HEREBY
     ACKNOWLEDGES AND AGREES THAT BANK WOULD NOT MAKE THE LOAN TO DEBTOR
     EVIDENCED BY THIS NOTE WITHOUT DEBTOR'S AGREEMENT, AS SET FORTH ABOVE, TO
     PAY BANK A PREPAYMENT FEE UPON THE SATISFACTION OF ALL OR ANY PORTION OF
     THE PRINCIPAL BEARING INTEREST AT A BASE INTEREST RATE FOLLOWING THE
     ACCELERATION OF THE MATURITY DATE HEREOF BY REASON OF A DEFAULT. DEBTOR HAS
     CAUSED THOSE PERSONS SIGNING THIS NOTE ON ITS BEHALF TO SEPARATELY INITIAL
     THE AGREEMENT CONTAINED IN THIS PARAGRAPH BY PLACING THEIR INITIALS BELOW:

     INITIALS:    
              -----------              -----------

5. DEFAULT AND ACCELERATION OF TIME FOR PAYMENT. "See Addendum "A", consisting
of two (2) pages, attached hereto and incorporated herein.

6. ADDITIONAL AGREEMENTS OF DEBTOR. If any amounts owing under this note are not
paid when due, Debtor promises to pay all costs and expenses, including
reasonable attorneys' fees, incurred by Bank in the collection or enforcement of
this note. Debtor and any endorsers of this note, for the maximum period of time
and the full extent permitted by law, (a) waive diligence, presentment, demand,
notice of nonpayment, protest, notice of protest, and notice of every kind; (b)
waive the right to assert the defense of any statute of limitations to any debt
or obligation hereunder; and (c) consent to renewals and extensions of time for
the payment of any amounts due under this note. If this note is signed by more
than one party, the term "Debtor" includes each of the undersigned and any
successors in interest thereof; all of whose liability shall be joint and
several. Any married person who signs this note agrees that recourse may be had
against the separate property of that person for any obligations hereunder. The
receipt of any check or other item of payment by Bank, at its option, shall not
be considered a payment on account until such check or other item of payment is
honored when presented for payment at the drawee bank. Bank may delay the credit
of such payment based upon Bank's schedule of funds availability, and interest
under this note shall accrue until the funds are deemed collected. In any action
brought under or arising out of this note, Debtor and any Obligor, including
their successors and assigns, hereby consent to the jurisdiction of any
competent court within the State of California, as provided in any alternative
dispute resolution agreement executed between Debtor and Bank, and consent to
service of process by any means authorized by said state's law. The term "Bank"
includes, without limitation, any holder of this note. This note shall be
construed in



                                      -2-

   18

accordance with and governed by the laws of the State of California. This note
hereby incorporates any alternative dispute resolution agreement previously,
concurrently or hereafter executed between Debtor and Bank.

7. DEFINITIONS. As used herein, the following terms shall have the meanings
respectively set forth below: "BASE INTEREST RATE" shall mean a rate of interest
based on the LIBOR-Rate. "BASE INTEREST RATE LOAN" shall mean amounts
outstanding under this note that bear interest at a Base Interest Rate. "BASE
RATE MATURITY DATE" shall mean the last day of the Interest Period with respect
to principal outstanding on which a Base Interest Rate has been selected by
Debtor. "BUSINESS DAY" shall mean a day which is not a Saturday or Sunday on
which Bank is open for business in the state identified in paragraph 6, above,
and, with respect to the rate of interest based on the LIBOR Rate, on which
dealings in U.S. dollar deposits outside of the United States may be carried on
by Bank. "INTEREST PERIOD" shall mean any calendar period of one, three, six,
nine or twelve months. In determining an Interest Period, a month means a period
that starts on one Business Day in a month and ends on and includes the day
preceding the numerically corresponding day in the next month. For any month in
which there is no such numerically corresponding day, then as to that month,
such day shall be deemed to be the last calendar day of such month. Any Interest
Period which would otherwise end on a non-Business Day shall and on the next
succeeding Business Day unless that is the first day of a month, in which event
such Interest Period shall and on the next preceding Business Day. "LIBOR RATE"
shall mean a per annum rate of interest (rounded upward, if necessary, to the
nearest 1/100 of 1%) at which dollar deposits, in immediately available funds
and in lawful money of the United States would be offered to Bank, outside of
the United States, for a term coinciding with the Interest Period selected by
Debtor and for an amount equal to the amount of principal covered by Debtor's
interest rate selection, plus Bank's costs, including the costs, if any, of
reserve requirements. "ORIGINATION DATE" shall mean the Business Day on which
funds are made available to Debtor relating to Debtor's selection of a Base

Rate is an index rate determined by Bank from time to time as a means of pricing
certain extensions of credit and is neither directly tied to any external rate
of interest or index nor necessarily the lowest rate of interest charged by Bank
at any given time.

==================================================================================================================================




$2,000,000.00                                                    Date_________


FOR VALUE RECEIVED, on SEPTEMBER 15, 2000, the undersigned ("Debtor") promises
to pay to the order of UNION BANK OF CALIFORNIA, N.A. ("Bank"), as indicated
below, the principal sum of TWO MILLION AND NO/100 Dollars ($2,000,000.00), or
so much thereof as is disbursed, together with interest on the balance of such
principal from time to time outstanding, at the per annum rate or rates and at
the times set forth below.

1.   PAYMENTS.

     PRINCIPAL PAYMENTS. Principal shall be payable in 36 equal consecutive
monthly instalments, each instalment in an amount sufficient to fully amortize
the principal balance by the final maturity date, beginning OCTOBER 15, 1997,
and continuing on the 15th day of each consecutive month. The availability under
this note shall be reduced on the same day and in the same amount as each
scheduled principal payment.

     INTEREST PAYMENTS. Debtor shall pay interest on the 15th day of each MONTH
(commencing MAY 15, 1997). Should interest not be paid when due, it shall become
part of the principal and bear interest as herein provided. All computations of
interest under this note shall be made on the basis of a year of 360 days, for
actual days elapsed.

     a. BASE INTEREST RATE. At Debtor's option, amounts outstanding hereunder in
     increments of at least $10,000 shall bear interest at a rate, based on an
     index selected by Debtor, which is 2.00% per annum in excess of Bank's
     LIBOR-Rate for the Interest Period so selected by Debtor.

     Any Base Interest Rate may not be changed, altered or otherwise modified
     until the expiration of the Interest Period selected by Debtor. The
     exercise of interest rate options by Debtor shall be as recorded in Bank's
     records, which records shall be prima facie evidence of the amount borrowed
     under either interest option and the interest rate; provided, however, that
     failure of Bank to make any such notation in its records shall not
     discharge Debtor from its obligations to repay in full with interest all
     amounts borrowed. In no event shall any Interest Period extend beyond the
     maturity date of this note.

     To exercise this option, Debtor may, from time to time with respect to
     principal outstanding on which a Base Interest Rate is not accruing, and on
     the expiration of any Interest Period with respect to principal outstanding
     on which a Base Interest Rate has been accruing, select an index offered by
     Bank for a Base Interest Rate Loan and Interest Period by telephoning an
     authorized lending officer of Bank located at the banking office identified
     below prior to 10:00 a.m., Pacific time, on any Business Day and advising
     that officer of the selected index, Interest Period and the Origination
     Date selected (which Origination Date, for a Base Interest Rate Loan based
     on the LIBOR-Rate, shall follow the date of such election by no more than
     two (2) Business Days).

     Bank will mail a written communication of the terms of the selection to
     Debtor promptly after the selection is made. Failure to send such
     confirmation shall not affect Bank's rights to collect interest at the rate
     selected. If, on the date of the selection, the index selected is
     unavailable for any reason, the selection shall be void. Bank reserves the
     right to fund the principal from any source of funds notwithstanding any
     Base Interest Rate selected by Debtor.

     b. VARIABLE INTEREST RATE. All principal outstanding hereunder which is not
     bearing interest at a Base Interest Rate shall bear interest at a rate per
     annum of 0.35% in excess of the Reference Rate, which rate shall vary as
     and when the Reference Rate changes.




                                      -1-
   23

     Debtor shall pay all amounts due under this note in lawful money of the
     United States at Bank's SAN DIEGO COMMERCIAL BANKING Office, or such other
     office as may be designated by Bank, from time to time.

2. LATE PAYMENTS. If any payment required by the terms of this note shall remain
unpaid ten days after same is due, at the option of Bank, Debtor shall pay a fee
of $100 to Bank.

3. INTEREST RATE FOLLOWING DEFAULT. In the event of default, at the option of
Bank, and, to the extent permitted by law, interest shall be payable on the
outstanding principal under this note at a per annum rate equal to five percent
(5%) in excess of the interest rate specified in paragraph 1.b, of this note,
calculated from the date of default until all amounts payable under this note
are paid in full.

4. PREPAYMENT.

     a. Amounts outstanding under this note bearing interest at a rate based on
     the Reference Rate may be prepaid in whole or in part at any time, without
     penalty or premium. Amounts outstanding under this note bearing interest at
     a Base Interest Rate may only be prepaid, in whole or in part provided Bank
     has received not less than five (5) Business Days prior written notice of
     an intention to make such prepayment and Debtor pays a prepayment fee to
     Bank in an amount equal to the present value of the product of: (i) the
     difference (but not lass than zero) between (a) the Base Interest Rate
     applicable to the principal amount which Debtor intends to prepay, and (b)
     the return which Bank could obtain if it used the amount of such prepayment
     of principal to purchase at bid price regularly quoted securities issued by
     the United States having a maturity date most closely coinciding with the
     relevant Base Rate Maturity Date and such securities were held by Bank
     until the relevant Base Rate Maturity Date ("Yield Rate"); (ii) a fraction,
     the numerator of which is the number of days in the period between the date
     of prepayment and the relevant Base Rate Maturity Date and the denominator
     of which is 360; and (iii) the amount of the principal so prepaid (except
     in the event that principal payments are required and have been made as
     scheduled under the terms of the Base Interest Rate Loan being prepaid,
     then an amount equal to the lesser of (A) the amount prepaid or (B) 50% of
     the sum of (1) the amount prepaid and (2) the amount of principal scheduled
     under the terms of the Base Interest Rate Loan being prepaid to be
     outstanding at the relevant Base Rate Maturity Date). Present value under
     this note is determined by discounting the above product to present value
     using the Yield Rate as the annual discount factor.

     b. In no event shall Bank be obligated to make any payment or refund to
     Debtor, nor shall Debtor be entitled to any setoff or other claim against
     Bank, should the return which Bank could obtain under the above prepayment
     formula exceed the interest that Bank would have received if no prepayment
     had occurred. All prepayments shall include payment of accrued interest on
     the principal amount so prepaid and shall be applied to payment of interest
     before application to principal. A determination by Bank as to the
     prepayment fee amount, if any, shall be conclusive. In the event of partial
     prepayment, such prepayments shall be applied to principal payments in the
     inverse order of their maturity.

     c. Such prepayment fee, if any, shall also be payable if prepayment occurs
     as the result of the acceleration of the principal of this note by Bank
     because of any default hereunder. If, following such acceleration, all or
     any portion of a Base Interest Rate Loan is satisfied, whether through sale
     of property encumbered by any security agreement or other agreement
     securing this note, at a foreclosure sale held thereunder or through the
     tender of payment at any time following such acceleration, but prior to
     such a foreclosure sale, then such satisfaction shall be deemed an evasion
     of the prepayment conditions set forth above, and Bank shall, automatically
     and without notice or demand, be entitled to receive, concurrently with
     such satisfaction the prepayment fee set forth above, and the amount of
     such prepayment fee shall be added to the principal. DEBTOR HEREBY
     ACKNOWLEDGES AND AGREES THAT BANK WOULD NOT MAKE THE LOAN TO DEBTOR
     EVIDENCED BY THIS NOTE WITHOUT DEBTOR'S AGREEMENT, AS SET FORTH ABOVE, TO
     PAY BANK A PREPAYMENT FEE UPON THE SATISFACTION OF ALL OR ANY PORTION OF
     THE PRINCIPAL BEARING INTEREST AT A BASE INTEREST RATE FOLLOWING THE
     ACCELERATION OF THE MATURITY DATE HEREOF BY REASON OF A DEFAULT. DEBTOR HAS
     CAUSED THOSE PERSONS SIGNING THIS NOTE ON ITS BEHALF TO SEPARATELY INITIAL
     THE AGREEMENT CONTAINED IN THIS PARAGRAPH BY PLACING THEIR INITIALS BELOW:

     INITIALS:

5. DEFAULT AND ACCELERATION OF TIME FOR PAYMENT See Addendum "A", consisting of
two (2) pages, attached hereto and incorporated herein.

6. ADDITIONAL AGREEMENTS OF DEBTOR. If any amounts owing under this note are not
paid when due, Debtor promises to pay all costs and expenses, including
reasonable attorneys' fees, incurred by Bank in the collection or enforcement
of this note. Debtor and any endorsers of this note, for the maximum period of
time and the full extent permitted by law, (a) waive diligence, presentment,
demand, notice of nonpayment, protest, notice of protest, and notice of every
kind; (b) waive the right to assert the defense of any statute of limitations to
any debt or obligation hereunder; and (c) consent to renewals and extensions of
time for the payment of any amounts due under this note. If this note is signed
by more than one party, the term "Debtor" includes each of the undersigned and
any successors in interest thereof; all of whose liability shall be joint and
several. Any married person who signs this note agrees that recourse may be had
against the separate property of that person for any obligations hereunder. The
receipt of any check or other item of payment by Bank, at its option, shall not
be considered a payment on account until such check or other item of payment is
honored when presented for payment at the drawee bank. Bank may delay the credit
of such payment based upon Bank's schedule of funds availability, and interest
under this note shall accrue until the funds are deemed collected. In any action
brought under or arising out of this note, Debtor and any Obligor, including
their successors and assigns, hereby consent to the jurisdiction of any
competent court within the State of





                                      -2-



   24

California, as provided in any alternative dispute resolution agreement executed
between Debtor and Bank, and consent to service of process by any means
authorized by said state's law. The term "Bank" includes, without limitation,
any holder of this note. This note shall be construed in accordance with and
governed by the laws of the State of California. This note hereby incorporates
any alternative dispute resolution agreement previously, concurrently or
hereafter executed between Debtor and Bank.

7. DEFINITIONS. As used herein, the following terms shall have the meanings
respectively set forth below: "BASE INTEREST RATE" shall mean a rate of interest
based on the LIBOR-Rate. "BASE INTEREST RATE LOAN" shall mean amounts
outstanding under this note that bear interest at a Base interest Rate. "BASE
RATE MATURITY DATE" shall mean the last day of the Interest Period with respect
to principal outstanding under a Base interest Rate Loan. "BUSINESS DAY" shall
mean a day which is not a Saturday or Sunday on which Bank is open for business
in the state identified in paragraph 6, above, and, with respect to the rate of
interest based on the LIBOR-Rate, on which dealings in U.S. dollar deposits
outside of the United States may be carried on by Bank. "INTEREST PERIOD" shall
mean with respect to funds bearing interest at a rate based on the LIBOR-Rate,
any calendar period of one, three, six, nine or twelve months. In determining an
Interest Period, a month means a period that starts on one Business Day in a
month and ends on and includes the day preceding the numerically corresponding
day in the next month. For any month in which there is no such numerically
corresponding day, then as to that month, such day shall be deemed to be the
last calendar day of such month. Any Interest Period which would otherwise end
on a non-Business Day shall end on the next succeeding Business Day unless that
is the first day of a month, in which event such Interest Period shall end on
the next preceding Business Day. "LIBOR RATE" shall mean a per annum rate of
interest (rounded upward, if necessary, to the nearest 1/100 of 1%) at which
dollar deposits, in immediately available funds and in lawful money of the
United States would be offered to Bank, outside of the United States, for a term
coinciding with the Interest Period selected by Debtor and for an amount equal
to the amount of principal covered by Debtor's interest rate election, plus
Bank's costs, including the cost, if any, of reserve requirements. "ORIGINATION
DATE" shall mean the Business Day on which funds are made available to Debtor
relating to Debtor's selection of a Base Interest Rate. "REFERENCE RATE" shall
mean the rate announced by Bank from time to time at its corporate headquarters
as its "Reference Rate." The Reference Rate is an index rate determined by Bank
from time to time as a means of pricing certain extensions of credit and is
neither directly tied to any external rate of interest or index nor necessarily
the lowest rate of interest charged by Bank at any given time.

$2,500,000.00                                                 Date____________

FOR VALUE RECEIVED, on SEPTEMBER 15, 2001, the undersigned ("Debtor") promises
to pay to the order of UNION BANK OF CALIFORNIA, N.A. ("Bank"), as indicated
below, the principal sum of TWO MILLION FIVE HUNDRED THOUSAND AND NO/100 Dollars
($2,500,000,00), or so much thereof as is disbursed, together with interest on
the balance of such principal from time to time outstanding, at the per annum
rate or rates and at the times set forth below.

1.   PAYMENTS.

     PRINCIPAL PAYMENTS. Principal shall be payable in 36 equal consecutive
monthly instalments, each instalment in an amount sufficient to fully amortize
the principal balance by the final maturity date, beginning OCTOBER 16, 1998,
and continuing on the 16th day of each consecutive month. The availability under
this note shall be reduced on the same day and in the same amount as each
scheduled principal payment.

     INTEREST PAYMENTS. Debtor shall pay interest on the 16th day of each MONTH
(commencing SEPTEMBER 16, 1997). Should interest not be paid when due, it shall
become part of the principal and bear interest as herein provided. All
computations of interest under this note shall be made on the basis of a year of
360 days, for actual days elapsed.

     a. BASE INTEREST RATE. At Debtor's option, amounts outstanding hereunder in
     increments of at least $10,000 shall bear interest at a rate, based on an
     index selected by Debtor, which is 2.00% per annum in excess of Bank's
     LIBOR-Rate for the Interest Period so selected by Debtor.

     Any Base Interest Rate may not be changed, altered or otherwise modified
     until the expiration of the Interest Period selected by Debtor. The
     exercise of interest rate options by Debtor shall be as recorded in Bank's
     records, which records shall be prima facie evidence of the amount borrowed
     under either interest option and the interest rate; provided, however, that
     failure of Bank to make any such notation in its records shall not
     discharge Debtor from its obligations to repay in full with interest all
     amounts borrowed. In no event shall any Interest Period extend beyond the
     maturity date of this note.

     To exercise this option, Debtor may, from time to time with respect to
     principal outstanding on which a Base Interest Rate is not accruing, and on
     the expiration of any Interest Period with respect to principal outstanding
     on which a Base Interest Rate has been accruing, select an index offered by
     Bank for a Base Interest Rate Loan and Interest Period by telephoning an
     authorized lending officer of Bank located at the banking office identified
     below prior to 10:00 a.m., Pacific time, on any Business Day and advising
     that officer of the selected index, Interest Period and the Origination
     Date selected (which Origination Date, for a Base Interest Rate Loan based
     on the LIBOR-Rate, shall follow the date of such election by no more than
     two (2) Business Days).

     Bank will mail a written communication of the terms of the selection to
     Debtor promptly after the selection is made. Failure to send such
     confirmation shall not affect Bank's rights to collect interest at the rate
     selected. If, on the date of the selection, the index selected is
     unavailable for any reason, the selection shall be void. Bank reserves the
     right to fund the principal from any source of funds notwithstanding any
     Base Interest Rate selected by Debtor.

     b. VARIABLE INTEREST RATE. All principal outstanding hereunder which is not
     bearing interest at a Base Interest Rate shall bear interest at a rate per
     annum of 0.35% in excess of the Reference Rate, which rate shall vary as
     and when the Reference Rate changes.




                                      -1-


   29

     Debtor shall pay all amounts due under this note in lawful money of the
     United States at Bank's SAN DIEGO COMMERCIAL BANKING Office, or such
     other office as may be designated by Bank, from time to time.

2. LATE PAYMENTS. If any payment required by the terms of this note shall remain
unpaid ten days after same is due, at the option of Bank, Debtor shall pay a fee
of $100 to Bank.

3. INTEREST RATE FOLLOWING DEFAULT. In the event of default, at the option of
Bank, and, to the extent permitted by law, interest shall be payable on the
outstanding principal under this note at a per annum rate equal to five percent
(5%) in excess of the interest rate specified in paragraph 1.b, of this note,
calculated from the date of default until all amounts payable under this note
are paid in full.

4. PREPAYMENT.

     a. Amounts outstanding under this note bearing interest at a rate based on
     the Reference Rate may be prepaid in whole or in part at any time, without
     penalty or premium. Amounts outstanding under this note bearing interest at
     a Base Interest Rate may only be prepaid, in whole or in part provided Bank
     has received not less than five (5) Business Days prior written notice of
     an intention to make such prepayment and Debtor pays a prepayment fee to
     Bank in an amount equal to the present value of the product of: (i) the
     difference (but not less than zero) between (a) the Base Interest Rate
     applicable to the principal amount which Debtor intends to prepay, and (b)
     the return which Bank could obtain if it used the amount of such prepayment
     of principal to purchase at bid price regularly quoted securities issued by
     the United States having a maturity date most closely coinciding with the
     relevant Base Rate Maturity Date and such securities were held by Bank
     until the relevant Base Rate Maturity Date ("Yield Rate"); (ii) a fraction,
     the numerator of which is the number of days in the period between the date
     of prepayment and the relevant Base Rate Maturity Date and the denominator
     of which is 360; and (iii) the amount of the principal so prepaid (except
     in the event that principal payments are required and have been made as
     scheduled under the terms of the Base Interest Rate Loan being prepaid,
     then an amount equal to the lesser of (A) the amount prepaid or (B) 50% of
     the sum of (1) the amount prepaid and (2) the amount of principal scheduled
     under the terms of the Base Interest Rate Loan being prepaid to be
     outstanding at the relevant Base Rate Maturity Date). Present value under
     this note is determined by discounting the above product to present value
     using the Yield Rate as the annual discount factor.

     b. In no event shall Bank be obligated to make any payment or refund to
     Debtor, nor shall Debtor be entitled to any setoff or other claim against
     Bank, should the return which Bank could obtain under the above prepayment
     formula exceed the interest that Bank would have received if no prepayment
     had occurred. All prepayments shall include payment of accrued interest on
     the principal amount so prepaid and shall be applied to payment of interest
     before application to principal. A determination by Bank as to the
     prepayment fee amount, if any, shall be conclusive. In the event of partial
     prepayment, such prepayments shall be applied to principal payments in the
     inverse order of their maturity.

     c. Such prepayment fee, if any, shall also be payable if prepayment occurs
     as the result of the acceleration of the principal of this note by Bank
     because of any default hereunder. If, following such acceleration, all or
     any portion of a Base Interest Rate Loan is satisfied, whether through sale
     of property encumbered by any security agreement or other agreement
     securing this note, at a foreclosure sale held thereunder or through the
     tender of payment at any time following such acceleration, but prior to
     such a foreclosure sale, then such satisfaction shall be deemed an evasion
     of the prepayment conditions set forth above, and Bank shall, automatically
     and without notice or demand, be entitled to receive, concurrently with
     such satisfaction the prepayment fee set forth above, and the amount of
     such prepayment fee shall be added to the principal. DEBTOR HEREBY
     ACKNOWLEDGES AND AGREES THAT BANK WOULD NOT MAKE THE LOAN TO DEBTOR
     EVIDENCED BY THIS NOTE WITHOUT DEBTOR'S AGREEMENT, AS SET FORTH ABOVE, TO
     PAY BANK A PREPAYMENT FEE UPON THE SATISFACTION OF ALL OR ANY PORTION OF
     THE PRINCIPAL BEARING INTEREST AT A BASE INTEREST RATE FOLLOWING THE
     ACCELERATION OF THE MATURITY DATE HEREOF BY REASON OF A DEFAULT. DEBTOR HAS
     CAUSED THOSE PERSONS SIGNING THIS NOTE ON ITS BEHALF TO SEPARATELY INITIAL
     THE AGREEMENT CONTAINED IN THIS PARAGRAPH BY PLACING THEIR INITIALS BELOW:


     INITIALS: /s/ [INITIALS]
               --------------

5. DEFAULT AND ACCELERATION OF TIME FOR PAYMENT* See Addendum "A", consisting of
two (2) pages, attached hereto and incorporated herein.

6. ADDITIONAL AGREEMENTS OF DEBTOR. If any amounts owing under this note are not
paid when due, Debtor promises to pay all costs and expenses, including
reasonable attorneys' fees, incurred by Bank in the collection or enforcement of
this note. Debtor and any endorsers of this note, for the maximum period of time
and the full extent permitted by law, (a) waive diligence, presentment, demand,
notice of nonpayment, protest, notice of protest, and notice of every kind; (b)
waive the right to assert the defense of any statute of limitations to any debt
or obligation hereunder; and (c) consent to renewals and extensions of time for
the payment of any amounts due under this note. If this note is signed by more
than one party, the term "Debtor" includes each of the undersigned and any
successors in interest thereof; all of whose liability shall be joint and
several. Any married person who signs this note agrees that recourse may be had
against the separate property of that person for any obligations hereunder. The
receipt of any check or other item of payment by Bank, at its option, shall not
be considered a payment on account until such check or other item of payment is
honored when presented for payment at the drawee bank. Bank may delay the credit
of such payment based upon Bank's schedule of funds availability, and interest
under this note shall accrue until the funds are deemed collected. In any action
brought under or arising out of this note, Debtor and any Obligor, including
their successors and assigns, hereby consent to the jurisdiction of any
competent court within the State of




                                      -2-

   30

California, as provided in any alternative dispute resolution agreement executed
between Debtor and Bank, and consent to service of process by any means
authorized by said state's law. The term "Bank" includes, without limitation,
any holder of this note. This note shall be construed in accordance with and
governed by the laws of the State of California. This note hereby incorporates
any alternative dispute resolution agreement previously, concurrently or
hereafter executed between Debtor and Bank.

7. DEFINITIONS. As used herein, the following terms shall have the meanings
respectively set forth below: "BASE INTEREST RATE" shall mean a rate of interest
based on the LIBOR-Rate. "BASE INTEREST RATE LOAN" shall mean amounts
outstanding under this note that bear interest at a Base Interest Rate. "BASE
RATE MATURITY DATE" shall mean the last day of the Interest Period with respect
to principal outstanding under a Base Interest Rate Loan. "BUSINESS DAY" shall
mean a day which is not a Saturday or Sunday on which Bank is open for business
in the state identified in paragraph 6, above, and, with respect to the rate of
interest based on the LIBOR-Rate, on which dealings in U.S. dollar deposits
outside of the United States may be carried on by Bank. "INTEREST PERIOD" shall
mean with respect to funds bearing interest at a rate based on the LIBOR-Rate,
any calendar period of one, three, six, nine or twelve months. In determining an
Interest Period, a month means a period that starts on one Business Day in a
month and ends on and includes the day preceding the numerically corresponding
day in the next month. For any month in which there is no such numerically
corresponding day, then as to that month, such day shall be deemed to be the
last calendar day of such month. Any Interest Period which would otherwise end
on a non-Business Day shall end on the next succeeding Business Day unless that
is the first day of a month, in which event such Interest Period shall end on
the next preceding Business Day. "LIBOR RATE" shall mean a per annum rate of
interest (rounded upward, if necessary, to the nearest 1/100 of 1%) at which
dollar deposits, in immediately available funds and in lawful money of the
United States would be offered to Bank, outside of the United States, for a term
coinciding with the Interest Period selected by Debtor and for an amount equal
to the amount of principal covered by Debtor's interest rate election, plus
Bank's costs, including the cost, if any, of reserve requirements. "ORIGINATION
DATE" shall mean the Business Day on which funds are made available to Debtor
relating to Debtor's selection of a Base Interest Rate. "REFERENCE RATE" shall
mean the rate announced by Bank from time to time at its corporate headquarters
as its "Reference Rate." The Reference Rate is an index rate determined by Bank
from time to time as a means of pricing certain extensions of credit and is
neither directly tied to any external rate of interest or index nor necessarily
the lowest rate of interest charged by Bank at any given time.
