                                      ARTICLE 2.
                                       GUARANTY

    SECTION 2.1.  GUARANTY OF THE OBLIGATIONS.  Guarantor unconditionally
guarantees and promises to pay to, or cause to be paid to, or to the order of,
Lender, on demand, in lawful money of Japan, any and all of the Obligations of
the Borrower to the Lender.  "Obligations" mean any amount due and payable to
Lender (including its successors and assigns) by Borrower (including its
successors and assigns) pursuant to any of the Loan Documents, including,
without limitation, principal and interest payable with respect to the Note,
interest at the Default Rate on late payments, any prepayment charges or
expenses, including Interest Rate Funding Costs and amounts which may become
payable under Section 2.9 (Change in Law), Section 2.10 (Capital Adequacy),
Section 8.5 (Costs and Expenses) and Section 8.7 (Indemnification) of the Loan
Agreement.  The unconditional obligations of Guarantor set forth herein
constitute the full recourse obligations of Guarantor enforceable against it to
the full extent of all its assets and properties.

    SECTION 2.2.  CONTINUING GUARANTY.  This is a continuing guaranty of the
Obligations and is a guaranty of payment and performance of the Obligations and
not of collection only.

    SECTION 2.3.  NATURE OF GUARANTY.  The liability of Guarantor hereunder is
independent of the obligations of Borrower and a separate action or separate
actions may be brought and prosecuted against Guarantor whether or not any
action is brought or prosecuted against Borrower or any other person, including
any other guarantor of the Obligations, or whether Borrower or any other person
is joined in any such action or actions.  The liability of Guarantor hereunder
is independent of and not in consideration of or contingent upon the liability
of any other person under this or any similar instrument and the release of, or
cancellation by, any signer of this or a similar



instrument shall not act to release or otherwise affect the liability of
Guarantor hereunder.  Guarantor waives the benefit of any statute of limitations
affecting its liability hereunder or the enforcement thereof to the fullest
extent permitted by law.

    SECTION 2.4.  AUTHORIZATION.  Guarantor hereby 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 otherwise change the terms of, the Obligations, or
    any part thereof, including increasing or decreasing the rate of interest
    thereon (but subject to the approval of Borrower to the extent required
    under the Loan Documents);

         (b)  amend with Borrower or waive any provision or provisions of the
    Loan Documents including the Note;

         (c)  take and hold security for the payment of the Obligations and
    exchange, enforce, waive or release any such security or any part thereof,
    and apply any such security and direct the order or manner of sale thereof
    as Lender, in its sole discretion, may determine; and

         (d)  release or substitute any one or more endorsers, guarantors
    and/or other obligors of this Guaranty and of the Obligations.

    SECTION 2.5.  WAIVERS.

         (a)   Guarantor waives the right to require Lender to proceed against
    or exhaust any security held from Borrower or any other person, or to
    pursue any other remedy in Lender's power whatsoever and Guarantor waives
    the right to have the property of Borrower first applied to the discharge
    of the Obligations.  Lender may at its election exercise any right or
    remedy it may have against Borrower or any security now or hereafter held
    by Lender, including, without limitation, the right to foreclose upon any
    such security by judicial or nonjudicial sale, without affecting or
    impairing in any way the liability of Guarantor hereunder, except to the
    extent the Obligations have been paid.  Guarantor understands that the
    exercise by Lender of certain rights and remedies contained in the Loan
    Documents (including without limitation, non-judicial foreclosure against
    any real property security for the Obligations) may affect or eliminate
    Guarantor's right of subrogation, contribution or indemnification against
    Borrower and that Guarantor may therefore succeed to a partially or totally
    nonreimbursable liability hereunder.  Nevertheless, Guarantor hereby
    authorizes and empowers Lender to exercise, in its sole discretion any
    rights and remedies or any combination of rights and remedies that may then
    be available, since it is the intent and purpose of Guarantor that the
    obligations hereunder shall be absolute, independent and unconditional
    under any and all circumstances.  Guarantor waives (i) 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, either in whole or in part, of Borrower to Lender for the
    Obligations; (ii) any defense based on the discharge of Borrower by
    operation of law, notwithstanding any intervention or omission by Lender
    and notwithstanding the provisions of section 2825 of the California Civil
    Code; (iii) all rights and benefits under section 726 of the California
    Code of Civil Procedure; and (iv) any defense based on arising out of the
    absence, impairment or loss of any right of reimbursement, contribution or
    subrogation or any other right or remedy of Guarantor against Borrower or
    any such security, whether resulting from such election by Lender or
    otherwise.

         (b)  Guarantor waives all rights and benefits under (i) section 2822
    of the California Civil Code purporting to reduce the obligation of a
    surety upon the acceptance by a creditor of anything in partial
    satisfaction of an obligation; (ii) section 2819 of the California Civil
    Code purporting to exonerate a surety if by any act of the creditor,
    without the consent of the surety, the original obligation of the principal
    is altered in any respect, or the remedies or rights of the creditor
    against the principal, in respect thereto, are in any way impaired or
    suspended (it being expressly understood and agreed that Lender may
    compromise, settle, alter, extend, waive, amend, suspend or surrender any
    Obligation or any right or remedy with respect thereto without notice to or
    consent by Guarantor and without affecting Guarantor's obligations
    hereunder); and (iii) section 2845 of the California Civil Code purporting
    to exonerate the surety to the extent that the creditor does not proceed
    against the principal, or pursue any other remedy in the creditor's power
    which the surety cannot pursue, and which would lighten the surety's
    burden.  Guarantor hereby waives, to the fullest extent permitted by law
    (a) all rights and benefits under section 2809 of the California Civil Code
    purporting to reduce a guarantor's obligations in proportion to the
    principal obligation; (b) all rights and benefits under sections 2810, 2899
    and 3433 of the California Civil Code; (c) all rights and benefits under
    section 580a of the California Code of Civil Procedure; (d) all rights and
    benefits under section 580b of the California Code of Civil Procedure
    stating that no deficiency may be  recovered on a real property purchase
    money obligation; and (e) all rights and benefits under section 580d of the
    California Code of Civil Procedure stating that no deficiency may be
    recovered on a Note secured by a deed of trust on real property in case
    such real property is sold under the power of sale contained in such deed
    of trust.  Guarantor fully understands that, without the waivers set forth
    in this Section 2.5, Guarantor would have a defense to a deficiency
    judgment under section 580d of the California Code of Civil Procedure
    should Lender elect to pursue nonjudicial foreclosure remedies, and
    nevertheless Guarantor expressly waives any and all benefits of any such
    defense to a deficiency judgment should Lender elect to exercise its
    nonjudicial foreclosure remedies (including waiver of Guarantor's defense
    under section 580d of the California Code of Civil Procedure).



         (c)  Without limiting the application of any of the other waivers
    contained herein, Guarantor hereby expressly waives all rights and defenses
    arising out of an election of remedies by Lender, even though that election
    of remedies, such as a nonjudicial foreclosure with respect to security for
    the guaranteed Obligations, has destroyed Guarantor's rights of subrogation
    and reimbursement against the principal (I.E., Borrower) by the operation
    of Section 580d of the California Code of Civil Procedure or otherwise.

          (d)  Guarantor understands and agrees that (i) by waiving the 
    anti-deficiency protections and the subrogation rights and defenses 
    referred to in this Section 2.5 and in Section 2.6 below, which 
    protections, rights and defenses might otherwise afford Guarantor with 
    protection from a deficiency judgment, Guarantor can be held liable for a 
    deficiency judgment following a judicial or non-judicial foreclosure sale 
    (including a judicial or non-judicial foreclosure sale of a purchase 
    money obligation) even if the price paid for the property at the 
    non-judicial foreclosure sale is less than the fair value of the 
    property; (ii) Guarantor is waiving its defense that the price paid for 
    the property at a judicial or non-judicial foreclosure sale may not be 
    equal to the fair value of the property; and (iii) by Guarantor waiving 
    its right to a fair value hearing following the foreclosure sale that 
    Lender can seek a deficiency against Guarantor up to the entire amount of 
    the indebtedness secured by any real property collateral  with interest 
    and costs of sale less the amount paid for the property at the judicial 
    or non-judicial foreclosure sale.

    SECTION 2.6.  ADDITIONAL WAIVERS; NO SUBROGATION.  Until all the
Obligations have been fully satisfied, Guarantor waives, to the fullest extent
permitted by law (i) all rights of subrogation, contribution or indemnification
against Borrower or any other right or remedy against Borrower arising from or
relating to this Guaranty; (ii) all rights and benefits under section 2848 of
the California Civil Code and any right to enforce any remedy which  Lender now
has or may hereafter have against Borrower in respect of the Obligations; (iii)
any benefit of, and any right to participate in, any security, whether real or
personal property, now or hereafter held by Lender for the Obligations; and (iv)
all rights and benefits under sections 2849 and 2850 of the California Civil
Code.  Guarantor waives all presentments, demands for performance, notices 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, whether existing, created or incurred under the Loan
Agreement, any modification thereof or otherwise.  Guarantor assumes the
responsibility for being and keeping informed of the financial condition of
Borrower and of all other circumstances bearing upon the risk of nonpayment of
the Obligations which diligent inquiry would reveal, and agrees that Lender
shall have no duty to advise Guarantor of information known to it regarding such
condition or any such circumstances.

    SECTION 2.7.  BANKRUPTCY NO DISCHARGE; REPAYMENTS.  So long as any of the
Obligations remain unpaid and owing to Lender, Guarantor shall not, without the
prior written consent of Lender, commence or join with any other party in
commencing any



bankruptcy, reorganization or insolvency proceedings of or against Borrower.
Guarantor understands and acknowledges that by virtue of this Guaranty,
Guarantor has specifically assumed any and all risks of a bankruptcy or
reorganization case or proceeding with respect to Borrower.  As an example and
not in any way of limitation, a subsequent modification of the Obligations in
any reorganization case concerning Borrower shall not affect the obligation of
Guarantor to pay and perform the Obligations in accordance with their respective
original terms.  If claim is ever made upon Lender for repayment of any amount
or amounts received by Lender in payment of the obligations under the Loan
Documents or hereunder (whether or not all or any part of such payment is
invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid by Lender) and Lender repays all or any part of said amount, then,
notwithstanding any revocation or termination of this Guaranty or the
cancellation of the Note or any other instrument evidencing the Loan, Guarantor
shall be and remain liable to Lender for the amount so repaid to the same extent
as if such amount had never originally been received by Lender.

    SECTION 2.8.  BORROWER.  It is not and shall not be necessary for Lender to
inquire into the powers of Borrower or any of their agents acting or purporting
to act on behalf thereof, and any Obligations made or created in reliance upon
the professed exercise of such powers shall be guaranteed hereunder.  Guarantor
agrees that Lender's books and records showing the account between Lender and
Borrower shall be admissible in any proceeding or action.


                                      ARTICLE 3.
                                      COVENANTS

    terms shall have the following meanings:

              "AFFILIATE" means, with respect to any Person (i) each Person
         that, directly or indirectly, owns or controls, whether beneficially
         or as a trustee, guardian or other fiduciary, ten percent (10%) or
         more of any class of Equity Securities of such Person; (ii) each
         Person that controls, is controlled by or is under common control with
         such Person or any Affiliate of such person; or (iii) each of such
         Person's officers, directors, joint venturers and partners; provided,
         however, that in no case shall Lender be deemed to be an Affiliate of
         Guarantor or any Subsidiary of Guarantor for purposes of this
         Guaranty.  For the purpose of this definition, "control" of a Person
         shall mean the possession, directly or indirectly, of the power to
         direct or cause the direction of its management or policies, whether
         through the ownership of voting securities, by contract or otherwise.



              "CAPITAL ASSET"  means, with respect to any Person, any tangible
         fixed or capital asset owned or leased (in the case of a Capital
         Lease) by such Person, or any expense incurred by such Person that is
         required by GAAP to be reported as a non-current asset on such
         Person's balance sheet.

         reasonably anticipated liability in respect thereof.

              Subsidiaries accruing during such period (to the extent deducted

         other equity interests in and of such Person (regardless of how
         designated and whether or not voting or non-voting); and (ii) all

         obligation of that Person, whether or not contingent (i) to purchase,
         repurchase or otherwise acquire such primary obligations or any
         property constituting direct or  indirect security therefor; (ii) to
         advance or provide funds (a) for the payment or discharge of any such
         primary obligation, or (b) to maintain working capital or equity
         capital of the primary obligor or otherwise to maintain the net worth
         or solvency or any balance sheet item, level of income or financial
         condition of the primary obligor; or (iii) to purchase property,
         securities or services primarily for the purpose of assuring the owner
         of any primary obligation of the ability of the primary obligor to
         make payment of such primary obligation; or (iv) otherwise to assure
         or hold harmless the holder of any such primary obligation against
         loss in respect thereof.  The amount of any Guaranty Obligation shall
         be deemed equal to the stated or determinable amount of the primary
         obligation in respect of which such Guaranty Obligation is made or, if
         not stated or if indeterminable, the maximum reasonably anticipated
         liability in respect thereof.

              or other title retention agreements with respect to property
              acquired by such Person (to the extent of the value of such
              property if the rights and remedies of the seller or lender under
              such agreement in the event of default are limited solely to
              repossession or sale of such property);

              respect to Capital Leases;

              right, contingent or otherwise, to be secured by) any Lien in any
              property (including accounts and contract rights) of such Person,
              even though such Person has not assumed or become liable for the
              payment of such Indebtedness.

              "INTEREST COVERAGE RATIO" means, with respect to any Person for
         any period, the ratio, determined on a consolidated basis in
         accordance with GAAP where applicable, of:

                   (i)  The remainder of (a) EBIT of such Person and its
              Subsidiaries for such period, MINUS (b) all Capital Expenditures
              of such Person and its Subsidiaries for such period;

    SECTION 4.1.  CURRENCY.  Guarantor shall make all payments due hereunder in
Japanese Yen and this obligation shall not be discharged by any tender or
judgment which is expressed in or converted into any currency other than
Japanese Yen, except to the extent resulting in the actual receipt by Lender of
the full amount of Japanese Yen payable hereunder.  Such obligation to pay in
Japanese Yen shall be enforceable as an additional cause of action to recover in
Japanese Yen the amount, if any, by which such actual receipt shall fall short
of the full amount of Japanese Yen payable hereunder.  If after the occurrence
of any Event of Default, any sum is due from Guarantor under this Guaranty or if
any order or judgment given or made in relation hereto has to be converted from

of:

           (i) making or filing a claim or proof against the Guarantor;

          (ii) obtaining an order or judgment in any court or tribunal; or

         (iii) enforcing any order or judgment given or made in relation
    hereto,

Guarantor shall indemnify and hold harmless Lender from and against any damages
or losses 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 rate or rates of exchange at
which Lender may in the ordinary



course of business purchase the first currency with the second currency in the
Japanese foreign exchange market upon receipt of a sum paid to it in
satisfaction, in whole or in part, of any such order, judgment, claim or proof.

    SECTION 4.2.  PAYMENTS FREE AND CLEAR OF TAXES.

         (a)  Any and all payments by Guarantor hereunder shall be made free
    and clear of and without deduction for any and all taxes, charges or levies
    ("Taxes").  If Guarantor shall be required by law to deduct any Taxes from
    or in respect of any sum payable hereunder (i) the sum payable shall be
    increased as may be necessary so that after making all required deductions
    (including deductions applicable to additional sums payable under this
    Section 4.2) Lender receives an amount equal to the sum it would have
    received had no such deductions been made, (ii) Guarantor shall make such
    deductions and (iii) Guarantor shall pay the full amount deducted to the
    relevant taxation authority or other authority in accordance with
    applicable law.  Notwithstanding anything to the contrary contained in this
    Section 4.2, Guarantor shall not be liable for the payment of any income,
    gross receipts or franchise taxes or other similar taxes with respect to
    any payment made by Guarantor pursuant to this Guaranty which is now or
    hereafter imposed on the overall net income of Lender.

         (b)  In addition, Guarantor agrees to pay any present or future stamp
    or documentary taxes, recording or filing fees or any other excise or
    property taxes, charges or similar levies which arise from any payment made
    hereunder or from the execution or delivery of or otherwise with respect to
    this Guaranty.

         (c)  Within ten (10) days after the date of any payment of Taxes by a
    Guarantor, Guarantor will furnish to Lender, at its principal office, the
    original or a certified copy of a receipt evidencing payment thereof.

    SECTION 4.3.  SURVIVAL OF WARRANTIES.  All agreements, representations and
warranties made herein shall survive the execution and delivery of this
Guaranty.

    SECTION 4.4.  FAILURE OR INDULGENCE NOT WAIVER.  No failure or delay on the
part of Lender in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
power, right or privilege preclude any other exercise of such powers, rights or
privileges.  The powers, rights and privileges hereunder are cumulative to, and
not exclusive of, any powers, rights or privileges otherwise available.

    SECTION 4.5.  RIGHTS TO SETOFF AND SUBROGATION.  In addition to all liens
upon, and rights to setoff against the moneys, securities or other property of
Guarantor given to Lender by law, Lender shall have a lien upon and a right of
setoff against all moneys, securities and other property of Guarantor now or
hereafter in the possession of or on deposit with Lender, whether held in a
general or special account or deposit, or for safekeeping or otherwise; and
every such lien and right of setoff may be exercised



without demand upon or notice to Guarantor.  No lien or right of setoff shall be
deemed to have been waived by any act or conduct on the part of Lender, or by
any neglect to exercise such right of setoff or to enforce such lien, or by any
delay in so doing; and every right of setoff and lien shall continue in full
force and effect until specifically waived or released by an instrument in
writing executed by Lender.

other jurisdiction.  To the extent that Guarantor has or hereafter may acquire
