               the Purchased Receivable, whether or not the Scheduled Due Date

               for the Purchased Receivable plus (B) the product of (1) the
               Discount Amount for the Purchased Receivable times (2) a fraction

               thousandth of one percent), the numerator of which is the number
               of days in the period commencing on the Closing Date and ending
               on the Repurchase Date and the denominator of which is the number

               Rate in effect from time to time during such period.

        (iii)  If the Scheduled Due Date HAS been set PRIOR to the Repurchase
               Date and the Repurchase Date occurs AFTER the Tentative Due Date
               but BEFORE the Scheduled Due Date for the Purchased Receivable,
               then the Seller shall pay a Repurchase Price equal to the sum of
               (A) the Face Amount of the Purchased Receivable plus (B) the
               Funded Interest Accrued Amount.

         (iv)  If the Scheduled Due Date HAS been set PRIOR to the Repurchase
               Date and the Repurchase Date occurs AFTER the Tentative Due Date
               and AFTER the Scheduled Due Date for the Purchased Receivable,
               then the Seller shall pay a Repurchase Price equal to the sum of

               Funded Interest Amount for the Purchased Receivable plus (C) an
               amount equal to the interest which would have accrued on the Face
               Amount from the Scheduled Due Date through the Repurchase Date at
               the Daily Rate in effect from time to time during such period.

In addition to the Repurchase Price payable by the Seller to the Purchaser on

                                    PAYMENTS

20.  CURRENCY OF ACCOUNT AND PAYMENT

20.1      Yen is the currency of account and payment for each and every sum at
any time due from any person hereunder, PROVIDED THAT:

          (i)  each payment in respect of costs and expenses shall be made in
               the currency in which the same were incurred; and

                                       36



         (ii)  each payment which is expressed herein to be payable in another
               currency shall be made in that other currency.

20.2      If any sum due from a person (a "relevant person") under this
Supplemental Agreement or any order or judgment given or made in relation hereto
has to be converted from the currency (the "first currency") in which the same
is payable hereunder or under such order or judgment into another currency (the
"second currency") for the purpose of (i) making or filing a claim or proof
against the relevant person, (ii) obtaining an order or judgment in any court or
other tribunal or (iii) enforcing any order or judgment given or made in
relation hereto, the relevant person shall indemnify and hold harmless the other
person to whom such sum is due from and against any loss suffered as a result of
any discrepancy between (a) the rate of exchange used for such purpose to
convert the sum in question from the first currency into the second currency and
(b) the best rate or rates of exchange at which such other person is reasonably
able to purchase the first currency with the second currency upon receipt of a
sum paid to it in satisfaction, in whole or in part, of any such order,
judgment, claim or proof.  To the extent that the person to whom such payment is
due receives an amount in excess of the amount due to it under this Supplemental
Agreement, such person shall forthwith pay an amount equal to any such excess to
the relevant person.

20.3      All payments made by any person hereunder shall be made free and clear
of and without any deduction for or on account of any set-off or counterclaim.

21.  PAYMENTS BY THE SELLER OR THE COLLECTION AGENT

21.1      On each date upon which this Supplemental Agreement requires an amount
to be paid by the Seller or the Collection Agent to the Purchaser hereunder, the
Seller or the Collection Agent (as the case may be) shall, save as expressly
provided otherwise herein, make the same available to the Purchaser:

          (i)  where such amount is denominated in Yen, by payment in Yen and in
               immediately available funds to such account and bank in Tokyo as
               the Purchaser shall have specified in writing for this purpose

                                       37



               at least two business days prior to such amount becoming payable;
               or

         (ii)  where such amount is denominated in a currency other than Yen, by
               payment in such currency and in immediately available, freely
               transferable, cleared funds to such account with such bank in the
               principal financial currency as the Purchaser shall have
               specified in writing for this purpose.

22.  PAYMENTS BY THE PURCHASER

22.1      On each date upon which this Supplemental Agreement requires an amount
to be paid to the Seller hereunder by the Purchaser, the Purchaser shall, save
as otherwise provided herein, make the same available to the Seller:

          (i)  where such amount is denominated in Yen, by payment in Yen and in
               immediately available funds to the Seller at such account and
               bank as the Seller shall have specified in writing for this
               purpose; or

         (ii)  where such amount is denominated in a currency other than Yen, by
               payment in such currency and in immediately available, freely
               transferable, cleared funds to such account with such bank in the
               principal financial centre of the country of such currency as the
               Seller shall have specified in writing for this purpose.

                                       38



                                     PART 10

                                      TAXES

23.  TAXES

23.1      All payments to be made by or on behalf of the Seller or the
Collection Agent to the Purchaser under or pursuant to any of the provisions of
this Supplemental Agreement shall be made free and clear of and without
deduction for or on account of tax unless the Seller or the Collection Agent (as
the case may be) is required by any applicable law to make such payment subject
to the deduction or withholding of tax in which case the sum payable by the
Seller or the Collection Agent (as the case may be) in respect of which such
deduction or withholding is required to be made shall be increased to the extent
necessary to ensure that, after the making of such deduction or withholding
(including any additional deduction or withholding on such increased amount),
the Purchaser receives and retains (free from any liability in respect of any
such deduction or withholding) a net sum equal to the sum which it would have
received and so retained had no such deduction or withholding been made or
required to be made.

23.2      If the Seller or the Collection Agent makes any payment to the
Purchaser under or pursuant to this Supplemental Agreement in respect of which
it is required to make any such deduction or withholding, the Seller or the
Collection Agent (as the case may be) shall deliver to the Purchaser as soon as
practicable a certificate of deduction of tax and/or a receipt or other evidence
issued by the relevant taxation or other authority demonstrating the payment to
such authority of all amounts so required to be deducted or withheld.

23.3      If an event occurs which would result in the Seller or the Collection
Agent becoming obliged to make any payment pursuant to this CLAUSE 23, then each
of the parties hereto shall in good faith use reasonable endeavors to take such
reasonable steps as may be open to it to mitigate or avoid the effects of such
event, PROVIDED THAT nothing in this CLAUSE 23.3 shall:

          (i)  oblige any party hereto to incur any costs or expenses or to take
               or refrain from taking any action where in the reasonable opinion
               of such

                                       39



               party to take or refrain from taking any action would be
               prejudicial to its interests; or

         (ii)  oblige any party hereto to disclose any confidential information
               relating to the organization of its affairs; or

        (iii)  interfere with the right of any party hereto to arrange its
               internal affairs in whatever manner it thinks fit.


                                     PART 11

                                   TERMINATION

24.  CONSEQUENCE OF A TERMINATION EVENT

24.1      Upon the occurrence of any Termination Event, other than the breach of
CLAUSE 11.3 or the occurrence of an Insolvency Event in relation to the Seller,
the Purchaser may, by notice to the Seller:

          (i)  terminate the obligation of the Purchaser to purchase any
               Receivable;

         (ii)  require the Seller to repurchase immediately the Purchased
               Receivable if the Scheduled Due Date has not been determined, in
               which event the provisions contained in CLAUSES 14.2 TO 14.4
               shall be applied MUTATIS MUTANDIS; and/or

        (iii)  exercise any and all other rights available to the Purchaser
               under this Supplemental Agreement or any of the other Transaction
               Documents or at law or in equity.

24.2      Upon the occurrence of any Insolvency Event in relation to the Seller,
automatically and without any notice to the Seller:

          (i)  the obligation of the Purchaser to purchase any Receivable shall
               terminate;

                                       40



         (ii)  the Seller shall repurchase immediately the Purchased Receivable
               if the Scheduled Due Date has not been determined, in which event
               the provisions contained in CLAUSES 14.2 TO 14.4 shall be applied
               MUTATIS MUTANDIS; and/or

        (iii)  the Purchaser may exercise any and all other rights available to
               the Purchaser under this Supplemental Agreement or any of the
               other Transaction Documents or at law or in equity.

24.3      Upon the breach of CLAUSE 11.3, the Seller shall, upon the request of
the Purchaser, deliver to the Purchaser either (i) funds in an amount equal to
the Face Amount of the Purchased Receivable or (ii) a standby letter of credit
with a stated amount equal to the Face Amount of the Purchased Receivable.

          (i)  The Purchaser shall hold any funds delivered to it pursuant to
               clause (i) of the first sentence of this CLAUSE 24.3 in an
               interest bearing account in the name of the Seller as security
               for the performance by the Seller of its obligations under this
               Supplemental Agreement and the other Transaction Documents.  The
               Seller hereby grants to the Purchaser, as security for such
               obligations, a security interest in such funds and such account
               and agrees to perform such other actions as the Purchaser may
               request to establish, perfect, maintain and protect such security
               interest prior to the rights of others in such funds and such
               account.

         (ii)  Any standby letter of credit delivered to the Purchaser pursuant
               to clause (ii) of the first sentence of this CLAUSE 24.3 shall be
               in a form and substance and issued by a bank acceptable to the
               Purchaser.  The Purchaser shall have the right to draw under any
               such letter of credit for any amounts payable to the Purchaser
               hereunder which are not paid to the Purchaser when due.

                                       41



Upon the payment or repurchase of the Purchased Receivable and the satisfaction
by the Seller of all its obligations under this Supplemental Agreement and the
other Transaction Documents, the Purchaser shall (A) deliver to the Seller the
funds, if any, remaining in any account established pursuant to clause (i) above
or (B) return to the Seller any letter of credit delivered to the Purchaser
pursuant to clause (ii) above, if any amounts remain available for drawing
thereunder.


                                     PART 12

                                  MISCELLANEOUS

25.  DEFAULT INTEREST AND INDEMNITY

25.1      If any sum due and payable by or on behalf of a party hereto (the
"Payer") to the other party (the "Payee") hereunder is not paid on the due date
therefor in accordance with the provisions hereof or if any sum due and payable
by the Payer under any judgment of any court in connection herewith is not paid
on the date of such judgment (the balance of such sum for the time being unpaid
being herein referred to as an "unpaid sum"), an unpaid sum shall bear interest
at the rate PER ANNUM which is equal to the Daily Rate plus two percent (2%),
such rate to change from time to time as the Daily Rate changes, for the period
beginning on, and including, such due date or, as the case may be, the date of
such judgment and ending on, but excluding, the date upon which the obligation
of the Payer to pay such sum is discharged (calculated on the basis of a year of
360 days).  Such default interest shall be payable upon demand of the Payee.

25.2      Each of the Seller and the Collection Agent undertakes to indemnify
the Purchaser against any loss or expense, including legal fees reasonably
incurred, which the Purchaser may sustain or incur as a consequence of any
default by the Seller or the Collection Agent (as the case may be) in the
performance of any of the obligations expressed to be assumed by it in this
Supplemental Agreement.

fees) incurred by it in or in connection with the negotiation, preparation and

Transaction Documents or any amendment thereto or any waiver thereof.

26.2      The Seller or the Collection Agent will, upon demand, pay to the

under this Supplemental Agreement, the Assignment or any other Transaction
Document or any amendment thereto or any waiver thereof.

28.1      No failure to exercise, nor any delay in exercising, on the part of
any party hereto, any right or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right or remedy prevent
any further or other exercise thereof or the exercise of any other right or
remedy.

28.2      The rights and remedies herein provided are cumulative and not
exclusive of any rights or remedies provided by law.

29.  PARTIAL INVALIDITY

     Without prejudice to any other provision hereof, if one or more provisions
hereof is or becomes invalid, illegal or unenforceable in any respect in any
jurisdiction or with respect to such party or parties, it shall not, to the

Seller (the "RECEIVABLE") upon the terms and subject to the conditions set forth
in the Supplemental Purchase Agreement and (ii) Seller has agreed to act as
collection agent for the Receivable so purchased by Purchaser from Seller (the
"PURCHASED RECEIVABLE").

     B.   Purchaser's obligation to purchase the Receivable from Seller under
the Supplemental Purchase Agreement is subject, among other conditions, to
receipt by Purchaser of this Guaranty, duly executed by Guarantor.


                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Guarantor hereby agrees with Purchaser as follows:

     1.   DEFINITIONS AND INTERPRETATION.

          (a)  DEFINITIONS.  Unless otherwise indicated in this Guaranty, each
     term set forth in SCHEDULE 1, when used in this Guaranty, shall have the
     respective meaning given to

     SCHEDULE 1.

          (b)  OTHER INTERPRETIVE PROVISIONS.  Headings in this Guaranty are for
     convenience of reference only and are not part of the substance hereof.
     All terms defined in this Guaranty in the singular form shall have
     comparable meanings when used in the plural form and VICE VERSA.  This
     Guaranty shall be governed by and construed in accordance with the laws of
     the State of California without reference to conflicts of law rules.
     References in this Guaranty to any document, instrument or agreement
     (i) shall include all exhibits, schedules and other attachments thereto,
     (ii) shall include all documents, instruments or agreements issued or
     executed in replacement thereof and (iii) shall mean such document,
     instrument or agreement, or replacement or predecessor thereto, as amended,

     time.

promises to pay and perform as and when due, upon the demand of Purchaser, (a)
all obligations of the obligor under the Purchased Receivable ("BUYER") and (b)
all obligations of Seller under the Supplemental Purchase Agreement and all

to be referred to herein collectively as the "GUARANTEED OBLIGATIONS").
Guarantor shall make all payments required hereunder to Purchaser, or its order,
at Purchaser's office located at the address set forth in SUBPARAGRAPH 8(A)
hereof, or at such other office as Purchaser may designate, on demand in such
lawful currency as is required by SUBPARAGRAPH 8(D) hereof.  Notwithstanding any
termination of this Guaranty in accordance with PARAGRAPH 6 hereof, this
Guaranty shall continue to be in full force and effect and applicable to any
Guaranteed Obligations arising thereafter which arise because prior payments of
Guaranteed Obligations are rescinded or otherwise required to be surrendered by
Purchaser after receipt.  The liability of Guarantor hereunder is independent of
the obligations of Seller and Buyer, and a separate action or actions may be
brought and prosecuted against Guarantor irrespective of whether action is
brought against

                                       7-2



Seller, Buyer or any other guarantor of the Guaranteed Obligations or whether
Seller, Buyer or any other guarantor of the Guaranteed Obligations is joined in
any such action or actions.  This Guaranty is a guaranty of payment and not of

Obligations, or (iii) pursue any other remedy in Purchaser's power whatsoever;
(b) any defense arising by reason of the application by Seller of the proceeds
of any purchase; (c) any defense resulting from the absence, impairment or loss
of any right of reimbursement, subrogation, contribution or other right or
remedy of Guarantor against Seller, Buyer, any other guarantor with respect to
the Guaranteed Obligations or any security, whether resulting from an election
by Purchaser to foreclose upon security by nonjudicial sale, or otherwise;
(d) any setoff or counterclaim of Seller or any defense which results from any
disability or other defense of Seller or the cessation or stay of enforcement
from any cause whatsoever of the liability of Seller (including, without
limitation, the lack of

                                       7-7



validity or enforceability of any Transaction Document); (e) any right to
exoneration of sureties which would otherwise be applicable; (f) until all
obligations of Purchaser under the Transaction Documents have been terminated
and the Guaranteed Obligations have been fully satisfied, any right of
subrogation or reimbursement and, if there are any other guarantors of the
Guaranteed Obligations, any right of contribution, and right to enforce any
remedy which Purchaser now has or may hereafter have against Seller, and any
benefit of, and any right to participate in, any security now or hereafter
received by Purchaser; (g) all presentments, demands for performance, notices of
non-performance, notices delivered under the Supplemental Purchase Agreement or

risk of nonpayment or nonperformance of the Purchased Receivable or Guaranteed
Obligations; and (k) any right to revoke this Guaranty prior to the termination
of the Transaction Documents and the satisfaction in full of all the Guaranteed
Obligations.  Guarantor has the ability and assumes the responsibility for
keeping informed of the financial condition of Seller, the Buyers and any other
guarantors of the Guaranteed Obligations and of other circumstances affecting
such nonpayment and nonperformance risks.  Without limiting the scope of any of
the foregoing waivers, Guarantor hereby waives (i) all rights and defenses
arising out of an election of remedies by Purchaser, even though that election
of remedies, such as a nonjudicial foreclosure with respect to security for a
Guaranteed Obligation, has destroyed Guarantor's rights of subrogation and
reimbursement against Seller by the operation of Section 580d of the Code of
Civil Procedure or otherwise, (ii) all rights and defenses Guarantor may have by
reason of protection afforded to Seller with respect to the Guaranteed
Obligations pursuant to the antideficiency or other laws of California limiting
or discharging the Guaranteed Obligations, including, without limitation,
Section 580a, 580b, 580d, or 726 of the California

                                       7-8



Code of Civil Procedure, and (iii) all other rights and defenses available to
Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil
Code.

     7.   SUBORDINATION.  Guarantor hereby subordinates any obligations of
Seller to Guarantor (the "SUBORDINATED OBLIGATIONS") to the Guaranteed
Obligations as provided in this PARAGRAPH 7.  Until the occurrence of a
Potential Termination Event or Termination Event, Guarantor may receive
regularly scheduled payments from Seller on account of Subordinated Obligations.
Upon the occurrence and during the continuance of any Potential Termination
Event or Termination Event, however:

          (a)  Purchaser shall be entitled to receive payment of all Guaranteed
     Obligations before Guarantor receives payment of any Subordinated
     Obligations;

          (b)  Any payments on the Subordinated Obligations, if Purchaser so
     requests, shall be collected, enforced and received by Guarantor as trustee
     for Purchaser and be paid over to Purchaser on account of the Guaranteed
     Obligations, but without reducing or affecting in any manner the liability
     of Guarantor under the other provisions of this Guaranty; and

          (c)  Purchaser is authorized and empowered (but without any obligation
     to so do), in its discretion, (i) in the name of Guarantor, to collect and
     enforce, and to submit claims in respect of, the Subordinated Obligations
     and to apply any amounts received thereon to the Guaranteed Obligations and
     (ii) to require Guarantor (A) to collect and enforce, and to submit claims
     in respect of, the Subordinated Obligations and (B) to pay any amounts

          (b)  EXPENSES.  Guarantor shall pay on demand, whether or not any
     Receivable is purchased under the Transaction Documents, (i) all reasonable
     fees and expenses, including reasonable attorneys' fees and expenses,
     incurred by Purchaser in connection with the preparation, execution and
     delivery of, and the exercise of its duties under, this Guaranty and the
     other Transaction Documents, and the preparation, execution and delivery of
     amendments and waivers hereunder and thereunder; and (ii) all reasonable
     fees and expenses, including reasonable attorneys' fees and

                                      7-10



     expenses, incurred by Purchaser in the enforcement or attempted enforcement
     of this Guaranty or any of the Guaranteed Obligations or in preserving any
     of Purchaser's rights and remedies (including, without limitation, all such
     fees and expenses incurred in connection with any "workout" or
     restructuring affecting the Transaction Documents or the Guaranteed
     Obligations or any bankruptcy or similar proceeding involving Guarantor,
     Seller or any of their affiliates).

          (c)  INDEMNIFICATIONS.  To the fullest extent permitted by law,
     Guarantor agrees to protect, indemnify, defend and hold harmless Purchaser
     and its affiliates and their respective directors, officers, employees,
     agents and advisors ("INDEMNITEES") from and against any and all
     liabilities, losses, damages or  expenses of any kind or nature and from
     any and all suits, claims or demands (including in respect of or for
     reasonable attorney's fees and other expenses) arising on account of or in
     connection with any matter or thing or action or failure to act by
     Indemnitees, or any of them, arising out of or relating to this Guaranty or
     the other Transaction Documents, including without limitation any use by
     Guarantor of any proceeds of any Receivable purchases, except to the extent
     such liability arises from the willful misconduct or gross negligence of
     the Indemnitees.  Upon receiving knowledge of any suit, claim or demand
     asserted by a third party that Purchaser believes is covered by this
     indemnity, Purchaser shall give Guarantor reasonable notice of the matter
     and an opportunity to defend it, at Guarantor's sole cost and expense, with
     legal counsel satisfactory to Purchaser.  Any failure or delay of Purchaser
     so to notify Guarantor of any such suit, claim or demand shall not relieve
     Guarantor of its obligations under this SUBPARAGRAPH 8(c) but shall reduce
     such obligations to the extent of any increase in those obligations caused
     solely by such failure or delay.  The obligations of Guarantor under this
     SUBPARAGRAPH 8(c) shall survive the payment and performance of the
     Guaranteed Obligations.

          (d)  CURRENCY OF PAYMENT.

               (i)  Guarantor shall make all payments of the Guaranteed
          Obligations hereunder in the currency in

                                      7-11



          which such Guaranteed Obligations are required to be paid by Seller
          pursuant to the other Transaction Documents and shall make all other
          payments hereunder in the lawful currency of the United States.

              (ii)  If any sum due from Guarantor under this Guaranty or any
          order or judgment given or made in relation hereto has to be converted
          from the currency (the "first currency") in which the same is payable
          hereunder or under such order or judgment into another currency (the
          "second currency") for the purpose of (A) making or filing a claim or
          proof against Guarantor with any Governmental Authority, (B) obtaining
          an order or judgment in any court or other tribunal or (C) enforcing
          any order or judgment given or made in relation hereto, Guarantor
          shall, to the fullest extent permitted by law, indemnify and hold
          harmless each of the Persons to whom such sum is due from and against
          any loss suffered as a result of any discrepancy between (1) the rate
          of exchange used for such purpose to convert the sum in question from
          the first currency into the second currency and (2) the rate or rates
          of exchange at which such Person may, using reasonable efforts in the
          ordinary course of business, purchase the first currency with the
          second currency upon receipt of a sum paid to it in satisfaction, in
          whole or in part, of any such order, judgment, claim or proof.  The
          foregoing indemnity shall constitute a separate obligation of
          Guarantor distinct from its other obligations hereunder and shall
          survive the giving or making of any judgment or order in relation to
          all or any of such obligations.

          (e)  WAIVERS; AMENDMENTS.  Any term, covenant, agreement or condition
     of this Guaranty may be amended or waived if such amendment or waiver is in
     writing and is signed by Guarantor and Purchaser.  No failure or delay by
     Purchaser in exercising any right hereunder shall operate as a waiver
     thereof or of any other right nor shall any single or partial exercise of
     any such right preclude any other further exercise thereof or of any other
     right.  Unless otherwise specified in such waiver or consent, a waiver or
     consent given hereunder shall be effective only in the

                                      7-12



     specific instance and for the specific purpose for which given.

          (f)  ASSIGNMENTS.  This Guaranty shall be binding upon and inure to
     the benefit of Guarantor and Purchaser and their respective successors and
     permitted assigns, except that Guarantor may not assign or transfer any of
     its rights or obligations under this Guaranty without the prior written
     consent of Purchaser.  All references in this Guaranty to any Person shall
     be deemed to include all successors and assigns of such Person.

          (g)  CUMULATIVE RIGHTS, ETC.  The rights, powers and remedies of
     Purchaser under this Guaranty shall be in addition to all rights, powers
     and remedies given to Purchaser by virtue of any applicable law, rule or
     regulation of any Governmental Authority, the other Transaction Documents
     or any other agreement, all of which rights, powers, and remedies shall be
     cumulative and may be exercised successively or concurrently without
     impairing Purchaser's rights hereunder.

          (h)  PAYMENTS FREE OF TAXES, ETC.  All payments made by Guarantor
     under this Guaranty shall be made by Guarantor free and clear of and
     without deduction for any and all present and future taxes, levies,
     charges, deductions and withholdings.  In addition, Guarantor shall pay
     upon demand any stamp or other taxes, levies or charges of any jurisdiction
     with respect to the execution, delivery, registration, performance and
     enforcement of this Guaranty.  If any taxes, levies, charges or other
     amounts are required to be withheld from any amounts payable to Purchaser
     hereunder, the amounts so payable to Purchaser shall be increased to the
     extent necessary to yield to Purchaser (after payment of all such amounts)
     any such amounts payable hereunder in the amounts specified in this
     Guaranty.  Upon request by Purchaser, Guarantor shall furnish evidence
     satisfactory to Purchaser that all requisite authorizations and approvals
     by, and notices to and filings with, governmental authorities and
     regulatory bodies have been obtained and made and that all requisite taxes,
     levies and charges have been paid.

                                      7-13



          (i)  PARTIAL INVALIDITY.  If at any time any provision of this
     Guaranty is or becomes illegal, invalid or unenforceable in any respect
     under the law or any jurisdiction, neither the legality, validity or
     enforceability of the remaining provisions of this Guaranty nor the
     legality, validity or enforceability of such provision under the law of any
     other jurisdiction shall in any way be affected or impaired thereby.

          (j)  JURY TRIAL.  EACH OF GUARANTOR AND PURCHASER, TO THE FULLEST
     EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT TO
     TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
     COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY.

          (k)  SUBMISSION TO JURISDICTION.  Guarantor hereby irrevocably and
     unconditionally:

               (i)  Submits for itself and its property in any legal action or
          proceeding relating to this Guaranty, or for recognition and
          enforcement of any judgment in respect thereof, to the non-exclusive
          jurisdiction of the courts of the State of California and the courts
          of the United States of America for the Northern District of
          California, and consents and agrees to suit being brought in such
          courts as Purchaser may elect;

              (ii)  Waives any objection that it may now or hereafter have to
          the venue of any such action or proceeding in any such court or that
          such proceeding was brought in an inconvenient court and agrees not to
          plead or claim the same; and

              (iii) Agrees that nothing herein shall affect Purchaser's right to
          effect service of process in any manner permitted by law, and that
          Purchaser shall have the right to bring any legal proceedings
          (including a proceeding for enforcement of a judgment entered by any
          of the aforementioned courts) against Guarantor in such courts or in
          any other court or jurisdiction in accordance with applicable law.

     IN WITNESS WHEREOF, Guarantor has caused this Guaranty to be executed as of
the day and year first above written.
