          terms and conditions of this Agreement, the Bank agrees to make
          Advances to Borrowers in an aggregate outstanding amount not to exceed
          the Domestic Committed Revolving Line or the Domestic Borrowing Base,
          whichever is less. Subject to the terms and conditions of this
          Agreement, amounts borrowed pursuant to this Section 2.1(a) may be
          repaid and reborrowed at any time during the term of this Agreement.

               (2) FOREIGN COMMITTED REVOLVING LINE. Subject to and upon the

          Each request for an Advance shall indicate whether it is to be made
          under the Domestic Committed Revolving Line or the Foreign Committed

immediately pay to the Bank, in cash, the amount of such excess.

               (1) INTEREST RATE. Except as set forth in Section 2.3(b), (i) any
          Advances under the Domestic Committed Revolving Line shall bear
          interest, on the average Daily Balance, at a rate equal to Prime Rate
          plus 1.25% and (ii) any Advances under the Foreign Committed Revolving
          Line shall bear interest at a per annum rate equal to Prime Plus
          1.50%.

               (2) DEFAULT RATE. All Obligations shall bear interest, from and

          (3) percentage points above the interest rate applicable immediately
          prior to the occurrence of the Event of Default.

               (3) PAYMENTS. Interest hereunder shall be due and payable on each
          Payment Date. Borrower hereby authorizes the Bank to debit any

          owing by Borrowers to the Bank. The Bank will notify each Borrower of
          all debits which the Bank has made against such Borrower's accounts.
          Any such debits against any Borrower's accounts in no way shall be
          deemed a set-off. Any interest not paid when due shall be compounded
          by becoming a part of the Obligations, and such interest shall
          thereafter accrue interest at the rate then applicable hereunder.

               (4) COMPUTATION. In the event the Prime Rate is changed from time
          to time hereafter, the applicable rate of interest hereunder shall be
          increased or decreased effective as of 12:01 a.m., California time, on
          the day the Prime Rate is changed, by an amount equal to such change
          in the Prime Rate. All interest chargeable under the Loan Documents
          shall be computed on the basis of a three hundred sixty (360) day year
          for the actual number of days elapsed.

     2.4 CREDITING PAYMENTS. Prior to the occurrence of an Event of Default, the
Bank shall credit a wire transfer of funds, check or other item of payment to
such deposit account or Obligation as the Borrowers specify. After the
occurrence of an Event of Default, the receipt by the Bank of any wire transfer
of funds, check, or other item of payment, whether directed to a Borrower's
deposit account with the Bank or to the Obligations or otherwise, may at the
election of the Bank be immediately applied to conditionally reduce Obligations,
but shall not be considered a payment in respect of the Obligations unless such
payment is of immediately available federal funds or unless and until such check
or other item of payment is honored when presented for payment. Notwithstanding
anything to the contrary contained herein, any wire transfer or payment received
by the Bank after 12:00 noon Pacific time shall be deemed to have been received
by the Bank as of the opening of business on the immediately following Business
Day. Whenever any payment to the Bank under the Loan Documents would otherwise
be due on a date that is not a Business Day,



<PAGE>

          Person, the Borrowers shall pay to the Bank a Termination Fee equal to
          one percent (1%) of the aggregate amount of the Committed Revolving
          Lines, provided, however, the Termination Fee shall be reduced by
          one-twelfth (1/12) on each monthly anniversary of the date hereof.

          Bank's applicable lending office is located or in which it is taxable
          solely on account of some connection other than the execution,
          delivery or performance of this Agreement or the receipt of income
          hereunder, it shall pay the Bank on the due date of the payment any
          additional amounts necessary (as determined by the Bank) to ensure
          that the Bank receives when due a net amount (after payment of any
          taxes in respect of those additional amounts) in the relevant currency
          equal to the full amount which it would have received had a deduction
          not been made. It shall, on demand, indemnify the Bank against the tax
          and any amounts recoverable from the Bank in respect of the tax.

               (4) The demand for additional payments under the preceding
          subsection (c) shall be accompanied by a certificate as to the amount
          of such additional payment required by the Bank which shall be
          conclusive absent manifest error. If the Bank is entitled to an
          exemption from or reduction of withholding tax under the law of the
          jurisdiction in which any of the Borrowers are located, or any treaty
          to which such jurisdiction is a party, with respect to payments under
          this Agreement, and the Borrowers so advise the Bank and the Borrowers
          deliver to the Bank an opinion of tax counsel or a letter of advice
          from an internationally recognized accounting firm acceptable to the
          Bank and its counsel as to the basis therefor which is acceptable to
          the Bank in form and substance, the Bank shall deliver to the
          Borrowers, at the time or times prescribed by applicable law or as
          reasonably requested by the Borrowers such properly completed and
          executed documentation prescribed by applicable law as will permit
          such payments to be made without withholding or at a reduced rate. If
          the Bank shall become aware that it is entitled to claim a refund from
          any taxing authority in respect of any taxes with respect to which the
          Borrower has paid increased amounts pursuant to this Section 2.8, the
          Bank shall notify the Borrower of the availability of such refund
          claim and shall exercise reasonable efforts to make the appropriate
          claim to the relevant government authority for such a refund. If the
          Bank receives a refund with respect to which the Borrower has paid
          increased amounts pursuant to this Section 2.8, it shall with
          reasonable promptness pay over such refund to the Borrower, net of all
          reasonable Bank Expenses incurred in connection therewith not
          previously paid by the Borrowers. The Borrowers agree that the
          obligations of the Bank under this clause (d) shall be expressly
          conditioned upon the Borrowers' agreement to pay all reasonable Bank
          Expenses incurred by the Bank in connection with or relating to the
          Bank's discharge of the foregoing obligations.

To the extent permitted under applicable law, the Borrowers waive any statutory
right to recover from the Bank any amount paid under this paragraph. The

Obligations and the termination of this Agreement.

duly authorized, and are not in conflict with nor constitute a breach of any
provision contained in any Borrower's organizational documents, nor will they
constitute an event of default under any material agreement to which any
Borrower is a party or by which any Borrower is bound. Except as disclosed in
SCHEDULE A, no Borrower is in default under any agreement to which it is a party

existing obligations. The property giving rise to such Eligible Accounts has
been delivered to the account debtor or to the account debtor's agent for
immediate shipment to and unconditional acceptance by the account debtor. Except
as disclosed to the Bank from time to time, no Borrower or any Subsidiary
thereof has received any notice of actual or imminent Insolvency Proceeding of
any account debtor that is included in any Domestic Borrowing Base Certificate
or Foreign Borrowing Base Certificate as an Eligible Account.

     5.5 MERCHANTABLE INVENTORY. All Inventory is in all material respects of
good and marketable quality, free from all material defects.

     5.6 INTELLECTUAL PROPERTY. Borrowers own or license all Intellectual
Property necessary for the conduct of their business. To the best of Borrowers'
knowledge, the ownership and use of the Intellectual Property does not infringe
or violate the rights of any third party and the Borrowers have not received any
claim or notice to such effect.

     5.7 NAME; LOCATION OF CHIEF EXECUTIVE OFFICE. Except as disclosed in
Schedule A, no Borrower has done business and will not without at least thirty

of any such pending or threatened actions or proceedings.

     5.9 NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All consolidated
financial statements related to Borrowers and any Subsidiary that have been
delivered by Borrowers to the Bank fairly present in all material respects

of Borrowers since the date of the most recent of such financial statements
submitted to the Bank on or about the Closing Date.

     5.10 SOLVENCY. The fair saleable value of each Borrower's assets (including

     5.11 REGULATORY COMPLIANCE. MC and each Subsidiary has met the minimum
funding requirements of ERISA with respect to any employee benefit plans subject
to ERISA to the extent applicable. No event has occurred resulting from any
Borrower's failure to comply with ERISA that is reasonably likely to result in
any Borrower's incurring any liability that could have a Material Adverse
Effect. No Borrower is an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940.
No Borrower is engaged principally, or as one of its the important activities,
in the business of extending credit for the purpose of purchasing or carrying

waste or hazardous substance other than in accordance with applicable law; to

the release, or other disposition of hazardous waste or hazardous substances
into the environment.

Subsidiaries to merge or consolidate, with or into any other business
organization, or acquire, or permit any of their Subsidiaries to acquire, all or
substantially all of the capital stock or property of another Person, provided,

another Subsidiary or into a Borrower.

<PAGE>

                                      -20-

and reasonable terms that are no less favorable to Borrowers than would be
obtained in an arm's length transaction with a nonaffiliated Person.

     7.9 INTELLECTUAL PROPERTY AGREEMENTS. Permit the inclusion in any material

might in any way prevent the creation of a security interest in a Borrower's

Obligations.

     8.2 COVENANT DEFAULT.

               (1) If any Borrower fails to perform any obligation under Section
          6.1, the second sentence of Section 6.2 or Section 6.5, violates any
          of the covenants contained in Article 7 of this Agreement or fails to

          observe any other material term, provision, condition, covenant, or
          agreement contained in this Agreement, in any of the Loan Documents,
          or in any other present or future agreement between any


<PAGE>

                                      -21-

          Borrower and the Bank and as to any default under such other
          term, provision, condition, covenant or agreement that can be cured,
          has failed to cure such default within ten (10) days after the
          occurrence thereof; provided, however, that if the default cannot by
          its nature be cured within the ten (10) day period or cannot after
          diligent attempts by such Borrower be cured within such ten (10) day
          period, and such default is likely to be cured within a reasonable
          time, then such Borrower shall have an additional reasonable period
          (which shall not in any case exceed thirty (30) days) to attempt to
          cure such default, and within such reasonable time period the failure
          to have cured such default shall not be deemed an Event of Default
          (provided that no Advances will be required to be made during such
          cure period);

     8.3 MATERIAL ADVERSE CHANGE. If there (i) occurs a material adverse change
in the business, operations, or condition (financial or otherwise) of any
Borrower, or (ii) is a material impairment of the prospect of repayment of any
portion of the Obligations or (iii) is a material impairment of the value or
priority of the Bank's security interests in the Collateral;

     8.4 ATTACHMENT. If any material portion of a Borrower's assets is attached,
seized, subjected to a writ or distress warrant, or is levied upon, or comes
into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within ten (10) days, or if a Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of the
assets of any Borrower, or if a notice of Lien or levy is filed of record with
respect to any assets of any Borrower by the United States government or the
Australian government, or any department, agency, or instrumentality thereof, or
by any state, county, municipal, or federal or foreign governmental agency, and
the same is not paid within twenty (20) days after such Borrower receives notice
thereof or any such Lien becomes enforceable or is enforced over any material
portion of a Borrower's assets or any material undertaking of a Borrower,
provided that none of the foregoing shall constitute an Event of Default where
such action or event is stayed or an adequate bond has been posted pending a
good faith contest by a Borrower (provided that if the amount involved exceeds
$100,000, no Credit Extensions will be required to be made during such cure
period);

     8.5 INSOLVENCY. If any Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by any Borrower, or if an Insolvency Proceeding is
commenced against any Borrower and is not dismissed or stayed within thirty (30)
days (provided that no Advances will be made prior to the dismissal of such
Insolvency Proceeding);

     8.6 OTHER AGREEMENTS. If there is a default in any agreement to which any
Borrower is a party with a third party or parties resulting in a right by such
third party or parties, whether or not exercised, to accelerate the maturity of
any Indebtedness in an amount in excess of One Hundred Thousand Dollars
($100,000) or that could have a Material Adverse Effect;

     8.7 SUBORDINATED DEBT. If any Borrower makes any payment on account of
Subordinated Debt, except to the extent such payment is allowed under any
subordination agreement entered into with the Bank;

     8.8 JUDGMENTS. If a judgment or judgments for the payment of money in an
amount, individually or in the aggregate, of at least One Hundred Thousand
Dollars ($100,000) shall be rendered against any Borrower and shall remain
unsatisfied and unstayed for a period of ten (10) days (provided that no Credit
Extensions will be made prior to the satisfaction or stay of such judgment); or

     8.9 MISREPRESENTATIONS. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth
herein or in any


<PAGE>


                                      -22-

certificate or writing delivered to the Bank by Borrower or any Person acting on
a Borrower's behalf pursuant to this Agreement or to induce the Bank to enter
into this Agreement or any other Loan Document.

     8.10 GUARANTY. Any guaranty of all or a portion of the Obligations ceases
for any reason to be in full force and effect, or any Guarantor fails to perform
any obligation under any guaranty of all or a portion of the Obligations, or any
material misrepresentation or material misstatement exists now or hereafter in
any warranty or representation set forth in any guaranty of all or a portion of
the Obligations or in any certificate delivered to the Bank in connection with
such guaranty, or any of the circumstances described in Sections 8.4, 8.5 or 8.8
occur with respect to any Guarantor.

9. BANK'S RIGHTS AND REMEDIES

     9.1 RIGHTS AND REMEDIES. Upon the occurrence and during the continuance of
an Event of Default, the Bank may, at its election, without notice of its
election and without demand, do any one or more of the following, all of which
are authorized by the Borrowers:

               (1) Declare all Obligations, whether evidenced by this Agreement,
          by any of the other Loan Documents, or otherwise, immediately due and
          payable (provided that upon the occurrence of an Event of Default
          described in Section 8.5 all Obligations shall become immediately due
          and payable without any action by the Bank);

               (2) Cease advancing money or extending credit to or for the
          benefit of Borrowers under this Agreement or under any other agreement
          between Borrowers and the Bank;

               (3) Settle or adjust disputes and claims directly with account
          debtors for amounts, upon terms and in whatever order that the Bank
          reasonably considers advisable;

               (4) Without notice to or demand upon Borrowers, make such
          payments and do such acts as the Bank considers necessary or
          reasonable to protect its security interest in the Collateral.
          Borrowers agree to assemble the Collateral if the Bank so requires,
          and to make the Collateral available to the Bank as the Bank may
          designate. Borrowers authorize the Bank to enter the premises where
          the Collateral is located, to take and maintain possession of the
          Collateral, or any part of it, and to pay, purchase, contest, or
          compromise any encumbrance, charge, or lien which in the Bank's
          determination appears to be prior or superior to its security interest
          and to pay all expenses incurred in connection therewith. With respect
          to any of Borrowers' premises, Borrowers hereby grant the Bank a
          license to enter such premises and to occupy the same, without charge,
          in order to exercise any of the Bank's rights or remedies provided
          herein, at law, in equity, or otherwise;

               (5) Without notice to Borrowers, set off and apply to the
          Obligations any and all (i) balances and deposits of any Borrower held
          by the Bank, or (ii) indebtedness at any time owing to or for the
          credit or the account of any Borrower held by the Bank;

               (6) Ship, reclaim, recover, store, finish, maintain, repair,
          prepare for sale, advertise for sale, and sell (in the manner provided
          for herein) the Collateral. The Bank is hereby granted a
          non-exclusive, royalty-free license or other right, solely pursuant to
          the provisions of this Section 9.1, to use, without charge, any
          Borrower's labels, patents, copyrights, mask works, rights of use of
          any name, trade secrets, trade names, trademarks, service marks, and
          advertising matter, or any property of a similar nature, as it
          pertains to the Collateral, in completing production of, advertising
          for sale, and selling any Collateral and, in connection with the
          Bank's exercise of its rights under this Section 9.1, each


<PAGE>


                                      -23-

          Borrower's rights under all licenses and all franchise agreements
          shall inure to the Bank's benefit;

               (7) Sell the Collateral at either a public or private sale, or
          both, by way of one or more contracts or transactions, for cash or on
          terms, in such manner and at such places (including any Borrower's
          premises) as the Bank determines is commercially reasonable, and apply
          the proceeds thereof to the Obligations in whatever manner or order it
          deems appropriate;

               (8) Credit bid and purchase at any public sale, or private sale
          as permitted by law;

               (9) Any deficiency that exists after disposition of the
          Collateral as provided above will be paid immediately by Borrowers on
          a joint and several basis, subject to the provisions of Section
          12.9(b);

               (10) The Bank shall have a non-exclusive, royalty-free license to
          use the Intellectual Property Collateral to the extent reasonably
          necessary to permit the Bank to exercise its rights and remedies upon
          the occurrence of an Event of Default; and

               (11) make a drawing under the Standby Letter of Credit to cover
          outstanding Obligations of the Borrowers hereunder. (The Bank agrees
          that it will not make such a drawing unless an Event of Default has
          occurred and is continuing.)

     9.2 POWER OF ATTORNEY. Effective only upon the occurrence and during the
continuance of an Event of Default, each Borrower hereby irrevocably appoints
the Bank (and any of the Bank's designated officers, or employees) as such
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of the Bank's security interest in the
Accounts; (b) endorse such Borrower's name on any checks or other forms of
payment or security that may come into the Bank's possession; (c) sign such
Borrower's name on any invoice or bill of lading relating to any Account, drafts
against account debtors, schedules and assignments of Accounts, verifications of
Accounts, and notices to account debtors; (d) make, settle, and adjust all
claims under and decisions with respect to such Borrower's policies of
insurance; (e) settle and adjust disputes and claims respecting the accounts
directly with account debtors, for amounts and upon terms which the Bank
determines to be reasonable; and (f) to file, in its sole discretion, one or
more financing or continuation statements and amendments thereto, relative to
any of the Collateral without the signature of such Borrower where permitted by
law; provided the Bank may exercise such power of attorney to sign the name of
such Borrower on any of the documents described in Section 4.2 regardless of
whether an Event of Default has occurred. The appointment of the Bank as each
Borrower's attorney in fact, and each and every one of the Bank's rights and
powers, being coupled with an interest, is irrevocable until all of the
Obligations have been fully repaid and performed and the Bank's obligation to
provide advances hereunder is terminated.

     9.3 ACCOUNTS COLLECTION. Upon the occurrence and during the continuance of
an Event of Default, the Bank may notify any Person owing funds to any Borrower
of the Bank's security interest in such funds and verify the amount of such
Account. Each Borrower shall collect all amounts owing to such Borrower for the
Bank, receive in trust all payments as the Bank's trustee, and if requested or
required by the Bank, immediately deliver such payments to the Bank in their
original form as received from the account debtor, with proper endorsements for
deposit.

     9.4 BANK EXPENSES. If any Borrower fails to pay any amounts or furnish any
required proof of payment due to third persons or entities, as required under
the terms of this Agreement, then the Bank may do any or all of the following:
(a) make payment of the same or any part thereof; (b) set up such reserves under
the Committed Revolving Lines as the Bank deems


<PAGE>


                                      -24-

necessary to protect the Bank from the exposure created by such failure; or (c)
obtain and maintain insurance policies of the type discussed in Section 6.6 of
this Agreement, and take any action with respect to such policies as the Bank
deems prudent. Any amounts so paid or deposited by the Bank shall constitute
Bank Expenses, shall be immediately due and payable, and shall bear interest at
the then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by the Bank shall not constitute an agreement by
the Bank to make similar payments in the future or a waiver by the Bank of any
Event of Default under this Agreement.

     9.5 BANK'S LIABILITY FOR COLLATERAL. So long as the Bank complies with
reasonable banking practices, the Bank shall not in any way or manner be liable
or responsible for: (a) the safekeeping of the Collateral; (b) any loss or
damage thereto occurring or arising in any manner or fashion from any cause; (c)
any diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrowers.

     9.6 REMEDIES CUMULATIVE. The Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative. The
Bank shall have all other rights and remedies not expressly set forth herein
inconsistent herewith as provided under the Code, by law, or in equity. No
exercise by the Bank of one right or remedy shall be deemed an election, and no
waiver by the Bank of any Event of Default on a Borrower's part shall be deemed
a continuing waiver. No delay by the Bank shall constitute a waiver, election,
or acquiescence by it. No waiver by the Bank shall be effective unless made in a
written document signed on behalf of the Bank and then shall be effective only
in the specific instance and for the specific purpose for which it was given.

     9.7 DEMAND; PROTEST. Each Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by the Bank on which such Borrower may in any way be
liable.

     9.8 CURRENT INDEMNITY

     (1) General

     On demand the Borrowers shall, on a joint and several basis, but subject to
     the provisions of Section 12.9(b), indemnify the Bank against any
     deficiency which arises whenever, for any reason (including as a result of
     a judgment or order or Insolvency Proceeding):

     (1)  the Bank receives or recovers an amount in one currency (the "Payment
          Currency") in respect of an amount denominated under a Loan Document
          in another currency (the "Due Currency"); and

     (2)  the amount actually received or recovered by the Bank in accordance
          with its normal practice when it converts the Payment Currency into
          the Due Currency is less than the relevant amount of the Due Currency.

     (2) Reimbursement

     Where an amount to be reimbursed or indemnified against under a Loan
     Document is denominated in another currency, if the Bank so requests, the
     Borrowers shall, on a joint and several basis but subject to the provisions
     of Section 12.9(b), reimburse or indemnify it against the amount of United
     States dollars which the Bank certifies


<PAGE>


                                      -25-

     that it used to buy the relevant amount of the other currency in accordance
     with its normal procedures. If the Bank does not so request, the Borrower
     shall reimburse or indemnify it in the relevant currency.

     12.1 SUCCESSORS AND ASSIGNS. This Agreement shall bind and inure to the
benefit of the respective successors and permitted assigns of each of the
parties; PROVIDED, HOWEVER, that neither this Agreement nor any rights hereunder
may be assigned by any Borrower without the Bank's prior written consent, which
consent may be granted or withheld in the Bank's sole discretion. The Bank shall
have the right without the consent of or notice to Borrowers to sell, transfer,

     12.7 SURVIVAL. All covenants, representations and warranties made in this
Agreement shall continue in full force and effect so long as any Obligations
remain outstanding. The obligations of Borrowers to indemnify the Bank with
respect to the expenses, damages, losses, costs and liabilities described in
Section 12.2 shall survive until all applicable statute of limitations periods
with respect to actions that may be brought against the Bank have run; provided
that so long as the obligations referred to in the first sentence of this
Section 12.7 have been satisfied, and the Bank has no commitment to make any
Credit Extensions or to make any other loans to Borrowers, the Bank shall
release all security interests granted hereunder and redeliver all Collateral
held by it in accordance with applicable law.

     12.8 COUNTERSIGNATURE. This agreement shall become effective only when it
shall have been executed by Borrowers and the Bank, provided, however, in no
event shall this agreement become effective until signed by an officer of the
Bank in California.

     12.9 JOINT AND SEVERAL OBLIGATIONS. (a) Subject to the provisions of
subparagraph (b) below, each and every representation, warranty, covenant and
agreement made by any of the Borrowers, hereunder and under the other Loan
Documents shall be joint and several, whether or not so expressed, and such
obligations of any of the Borrowers shall not be subject to any counterclaim,
setoff, recoupment or defense based upon any claim any Borrower may have against
any other Borrower or the Bank, and shall remain in full force and effect
without regard to, and shall not be released, discharged or in any way affected
by, any circumstance or condition affecting any other Borrower, including
without limitation (b) any waiver, consent, extension, renewal, indulgence or
other action or inaction under or in respect of this Agreement or any other Loan
Document, or any agreement or other document related thereto with respect to any
other Borrower, or any exercise or nonexercise of any right, remedy, power or
privilege under or in respect of any such agreement or instrument with respect
to the other Borrower, or the failure to give notice of any of the foregoing to
the other Borrower; (c) any invalidity or unenforceability, in whole or in part,
of any such agreement or instrument with respect to any other Borrower; (d) any
failure on the part of any other Borrower for any reason to perform or comply
with any term of any such agreement or instrument; (e) any bankruptcy,
insolvency, reorganization, arrangement, readjustment, composition, liquidation
or similar proceeding with respect to any other Borrower or its properties or
creditors; or (f) any other occurrence whatsoever, whether similar or dissimilar
to the foregoing, with respect to any other Borrower. Each Borrower hereby
waives any requirement of diligence or promptness on the part of the Bank in the
enforcement of its rights hereunder or under any other Loan Document with
respect to the obligations of itself or of the other Borrowers. Without limiting
the foregoing, any failure to make any demand upon, to pursue or exhaust any
rights or remedies against a Borrower, or any delay with respect thereto, shall
not affect the obligations of the other Borrowers hereunder or under any other
Loan Document.

     (b) Notwithstanding the provisions of subparagraph (a) above or anything in
this Loan Agreement or any other Loan Documents to the contrary, the obligations
of MPL and MIPL shall not be joint and several with respect to any
representation, warranty, covenant and agreement made by MC, or any obligation
incurred by MC hereunder or under any other Loan Document, for which MC alone
shall be responsible. The intent of this subparagraph being to prevent any
interpretation or construction of this Loan Agreement or any other Loan Document
under which MIPL or MPL could be construed as providing any form of credit
support for the Obligations of MC to the Bank.

     12.10 MC AS AGENT FOR BORROWERS. Each MIPL and MPL hereby appoints MC as
its agent with respect to the receiving and giving of any notices, requests,
instructions, reports, schedules, revisions, financial statements or any other
written or oral communications hereunder or under the Loan Documents. MC shall
keep complete, correct and accurate records of all Revolving Line of Credit
Loans and the application of proceeds thereof, all Letters of Credit and all
payments in respect of Advances and other amounts due hereunder. The Bank is
hereby entitled to rely on any communications given or transmitted by MC as if
such communication were given or transmitted by each and every Borrower;
PROVIDED, HOWEVER, that any communication given or transmitted by any Borrower
other than MC shall be binding with respect to such Borrower. Any

                         AGREEMENT TO PROVIDE INSURANCE

GRANTOR:  Moldflow Corporation                       BANK:  Silicon Valley Bank

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

     INSURANCE REQUIREMENTS. Moldflow Corporation ("Grantor") understands that
insurance coverage is required in connection with the extending of a loan or the
providing of other financial accommodations to Grantor, Moldflow International
Pty. Ltd. and Moldflow Pty. Ltd. by the Bank. These requirements are set forth
in the Loan Documents. The following minimum insurance coverages must be
provided on the following described collateral (the "Collateral"):

Collateral:        All Inventory, Equipment and Fixtures.
Type:              All risks, including fire, theft and liability.

Amount:            Full insurable value.
Basis:             Replacement value.

Endorsements:      Loss payable clause to the Bank with
                   stipulation that coverage will not be
                   cancelled or diminished without a minimum
                   of twenty (20) days' prior written notice
                   to the Bank.

     INSURANCE COMPANY. Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to the Bank. Grantor
understands that credit may not be denied solely because insurance was not
purchased through the Bank.

     FAILURE TO PROVIDE INSURANCE. Grantor agrees to deliver to the Bank, on or
before closing, evidence of the required insurance as provided above, with an
effective date of , 19___, or earlier. Grantor acknowledges and agrees that if
Grantor fails to provide any required insurance or fails to continue such
insurance in force, the Bank may do so at Grantor's expense as provided in the
Loan Agreement. The cost of such insurance, at the option of the Bank, shall be
payable on demand or shall be added to the indebtedness as provided in the
security document. GRANTOR ACKNOWLEDGES THAT IF THE BANK SO PURCHASES ANY SUCH
INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION AGAINST PHYSICAL DAMAGE
TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN; HOWEVER, GRANTOR'S EQUITY IN
THE COLLATERAL MAY NOT BE INSURED. IN ADDITION, THE INSURANCE MAY NOT PROVIDE
ANY PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION AND MAY NOT MEET THE
REQUIREMENTS OF ANY FINANCIAL RESPONSIBILITY LAWS.

     AUTHORIZATION. For purposes of insurance coverage on the Collateral,
Grantor authorizes the Bank to provide to any person (including any insurance
agent or company) all information the Bank deems appropriate, whether regarding
the Collateral, the loan or other financial accommodations, or both.

     GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO
PROVIDE INSURANCE AND AGREES TO ITS TERMS.  THIS AGREEMENT IS DATED
___________________________, 19___.

GRANTOR:
