2. LOAN AND TERMS OF PAYMENT

2.1.1 Revolving Advances. Subject to the terms and conditions of this Exim
Agreement, Bank agrees to make Advances to Borrower in an amount not to exceed
the Exim Committed Line or the Borrowing Base, whichever is less, minus the then
outstanding principal balance of the Advances.

         To evidence the Advances, Borrower shall execute and deliver to Bank on
the date hereof a promissory note (the "Note") in substantially the form
attached hereto as EXHIBIT B.

         Whenever Borrower desires an Advance, Datawatch US will notify Bank by
facsimile transmission or telephone no later than 3:00 p.m. Eastern time, on the
Business Day that the Advance is to be made. Each such notification shall be
promptly confirmed by a Payment/Advance Form in substantially the form of
EXHIBIT C hereto together with any additional documentation required under the
Borrower Agreement, including without limitation, as set forth in Section 2.03
of the Borrower Agreement. In addition to the procedure set forth in the
preceding sentence, Bank is authorized to make Advances under this Exim
Agreement based upon instructions received from a Responsible Officer of
Datawatch US or without instructions if in Bank's discretion such Advances are
necessary to meet Obligations which have become due and remain unpaid. Bank
shall be entitled to rely on any telephonic notice given by a person who Bank
reasonably believes to be a Responsible Officer of Datawatch US or a designee
thereof, and Borrower shall indemnify and hold Bank harmless for any damages or
loss suffered by Bank as a result of such reliance. Bank will credit the amount
of Advances made under this Section 2.1.1 to Borrower's deposit account. Amounts
borrowed pursuant to this Section 2.1.1 may be repaid at any time and
re-borrowed at any time during the term of this Exim Agreement so long as no
Event of Default has occurred and is continuing.

                  Only Datawatch US may request Advances hereunder.
Notwithstanding the foregoing, each Borrower hereunder shall be obligated to
repay all Advances made hereunder, regardless of which Borrower actually
receives said Advance, as if each Borrower hereunder directly received all
Advances. Each Borrower acknowledges and agrees that, to the extent the other
Borrower has or may have certain rights of subrogation or reimbursement against
the other for claims arising out of this Exim Agreement, that those rights are
hereby waived.

2.2 Overadvances. If, at any time or for any reason, the amount of Obligations
pursuant to this Exim Agreement owed by Borrower to Bank pursuant to Section
2.1.1 of this Exim Agreement is greater than the lesser of

                                       4
<PAGE>

(i) the Borrowing Base or (ii) the Exim Committed Line, Borrower shall
immediately pay to Bank, in cash, the amount of such excess.

2.3 Interest Rates, Payments, and Calculations.

(a) Interest Rate. Except as set forth in Section 2.3(b), or as specified to the
contrary in any Loan Document, any Advances under this Exim Agreement shall bear
interest, on the average daily balance, at a rate equal to the Prime Rate plus
one percent (1.0%) per annum.

(b) Default Rate. All Obligations shall bear interest, after the occurrence and
during the continuance of an Event of Default, at a rate equal to five (5%)
percentage points above the interest rate that applied immediately prior to the
occurrence of the Event of Default.

(c) Payments. Interest hereunder shall be due and payable on the first (1st) day
of each month. Bank shall, at its option, charge such interest, all Exim Bank
Expenses, and all Periodic Payments against Borrower's deposit account or
against the Exim Committed Line, in which case those amounts shall thereafter
accrue interest at the rate then applicable hereunder.

(d) 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 contemporaneously with such change by an amount equal to such change
in the Prime Rate. All interest chargeable under the Exim 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. The receipt by Bank of any wire transfer of funds,
check, or other item of payment shall be immediately applied to conditionally
reduce Obligations, but shall not be considered a payment on account unless such
wire transfer is of immediately available federal funds and is made to the
appropriate deposit account of Bank 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 payment (other than a wire transfer of
immediately available funds) received by Bank after 12:00 p.m. (noon) Eastern
time shall be deemed to have been received by Bank as of the opening of business
on the immediately following Business Day.

2.5 Fees. Borrower shall pay to Bank the following fees:

         (a) Financial Examination and Appraisal Fees. Bank's customary fees and
         out-of-pocket expenses for Bank's audits of Borrower's Accounts and
         financial analysis and examination of Borrower performed from time to
         time by Bank or its agents;

         (b) Exim Fee. A facility fee equal to Thirty Thousand Dollars
         ($30,000.00), which fee shall be due and fully earned upon the Closing
         Date; and

         (c) Exim Bank Expenses. On the Closing Date, Exim Bank Expenses
         incurred through the Closing Date and, after the Closing Date, all Exim
         Bank Expenses as they become due, if any.

2.6 Additional Costs. In case any law, regulation, treaty or official directive
or the interpretation or application thereof by any court or any governmental
authority charged with the administration thereof or the compliance with any
guideline or request of any central bank or other governmental authority
(whether or not having the force of law):

         (a) subjects Bank to any tax with respect to payments of principal or
         interest or any other amounts payable hereunder by Borrower or
         otherwise with respect to the transactions contemplated hereby (except
         for taxes on the overall net income of Bank imposed by the United
         States of America or any political subdivision thereof);

         (b) imposes, modifies or deems applicable any deposit insurance,
         reserve, special deposit or similar requirement against assets held by,
         or deposits in or for the account of, or loans by, Bank; or

                                       5
<PAGE>

         (c) imposes upon Bank any other condition with respect to its
         performance under this Agreement,

and the result of any of the foregoing is to increase the cost to Bank, reduce
the income receivable by Bank or impose any expense upon Bank with respect to
any loans, Bank shall promptly notify Borrower thereof. Borrower agrees to pay
to Bank the amount of such increase in cost, reduction in income or additional
expense as and when such cost, reduction or expense is incurred or determined,
upon presentation by Bank of a statement of the amount and setting forth Bank's
calculation thereof, all in reasonable detail, which statement shall be deemed
true and correct absent manifest error.

2.7 Term. This Exim Agreement shall become effective once duly executed and
authorized by Borrower and Bank and shall continue in full force and effect for
a term ending on the Exim Maturity Date, on which date all Obligations shall
become immediately due and payable. Notwithstanding the foregoing, Bank shall
have the right to terminate this Exim Agreement immediately and without notice
upon the occurrence of an Event of Default. Notwithstanding any termination of
this Exim Agreement, Bank's security interest in all of the Collateral and all
of the terms and provisions of this Exim Agreement shall continue in full force
and effect until all Obligations have been paid and performed in full, and no
termination shall impair any right or remedy of Bank, nor shall any such
termination relieve Borrower of any Obligation to Bank until all of the
Obligations have been paid and performed in full.

2.8 Use of Proceeds. Borrower will use the proceeds of Advances only for the
purposes specified in the Borrower Agreement. Borrower shall not use the
proceeds of the Advances for any purpose prohibited by the Borrower Agreement.

3. CONDITIONS OF LOANS

Advance, including the initial Advance, is subject to the following conditions:

         (a) timely receipt by Bank of the Payment/Advance Form as provided in
         Section 2.1;

         (b) timely receipt by Bank of a Borrowing Base Certificate as defined

         extent they relate specifically to an earlier date, in which case such
         representations and warranties shall continue to have been true and
         accurate as of such date), and no potential Event of Default or Event
         of Default shall have occurred and be continuing, or would result from
         such Advance.

         The making of each Advance shall be deemed to be a representation and
warranty by Borrower on the date of such Advance as to the accuracy of the facts

4. CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest. Borrower grants and pledges to Bank a continuing
security interest in all presently existing and hereafter acquired or arising
Collateral in order to secure prompt payment of any and all Obligations (which
Obligations shall include, without limitation, all obligations of the Borrower
to the Bank under the Domestic Loan Documents) and in order to secure prompt
performance by Borrower of each of its covenants and duties under the Exim Loan
Documents and Domestic Loan Documents. Except for Permitted Liens or as set
forth in the Schedule, such security interest constitutes a valid, first
priority security interest in the presently existing Collateral, and will
constitute a valid, first priority security interest in Collateral acquired
after the date hereof. Borrower acknowledges that Bank may place a "hold" on any
Deposit Account pledged as Collateral to secure the Obligations. Notwithstanding
termination of this Agreement, Bank's Lien on the Collateral shall remain in
effect for so long as any Obligations are outstanding. Notwithstanding the
foregoing, it is expressly acknowledged and agreed that the security interest
created in this Exim Agreement in all of the Collateral, with the exception of
Exim Eligible Foreign Accounts (but only to the extent any Advances are actually
made by the Bank to the Borrower based upon such Exim Eligible Foreign
Accounts), is subject to and subordinate to the security interest granted to the
Bank in the Domestic Agreement with respect to the Collateral.

4.2 Delivery of Additional Documentation Required. Borrower shall from time to
time execute and deliver to Bank, at the request of Bank, all financing
statements and other documents that Bank may reasonably request, in form
satisfactory to Bank, to perfect and continue perfected Bank's security
interests in the Collateral and in order to fully consummate all of the
transactions contemplated under the Exim Loan Documents.

4.3 Right to Inspect. Each of Bank and Exim Bank (through any of their
respective officers, employees, or agents) shall have the right, upon reasonable
prior notice, from time to time during Borrower's usual business hours, to
inspect Borrower's Books, facilities and activities, and to check, test, and
appraise the Collateral in order to verify Borrower's financial condition or the
amount, condition of, or any other matter relating to, the Collateral. The Bank
may, in its discretion, elect to inspect the books and records of any one or
more of the Guarantors at the chief executive office of Datawatch US and the
Borrower shall cooperate with the Bank in such regard and make the books and
records of each of the Guarantors available to the Bank at such location upon

provided that (i) such audits will be conducted no more often than every six (6)
months unless an Event of Default has occurred and is continuing, and (ii) Bank
may, in its discretion, elect to conduct such audits of any one or more of the
Guarantors at the chief executive office of Datawatch US and the Borrower shall
cooperate with the Bank in such regard and make the pertinent books and records
of each of the Guarantors available to the Bank at such location upon reasonable
prior notice . Borrower will cause its officers and employees to give their full
cooperation and assistance in connection therewith. The initial Advance
hereunder shall be subject to a field audit satisfactory to the Bank in its
discretion, the costs of which shall be borne by the Borrower.

Default by Borrower under this Exim Agreement:

under any of the Domestic Loan Documents or the Borrower Agreement and as to any
such failure, neglect, or Event of Default 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 Borrower be cured within such
ten (10) day period, and such default is likely to be cured within a reasonable
time, then 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);

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 Bank in connection with such
guaranty, or any of the circumstances described in Sections , 8.6, or 8.7 of the
Domestic Agreement shall occur with respect to any Guarantor;

Domestic Loan Documents) with respect to the Domestic Loan Documents.

9. BANK'S RIGHTS AND REMEDIES

9.1 Rights and Remedies. Upon the occurrence and during the continuance of an
Event of Default, 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 Borrower:

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

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

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

         (d) Notify customers of Borrower or other third parties to pay amounts
         owing to Borrower directly to the Bank;

         (e) Without notice to or demand upon Borrower, make such payments and
         do such acts as Bank considers necessary or reasonable to protect its
         security interest in the Collateral. Borrower agrees to assemble the
         Collateral if Bank so requires, and to make the Collateral available to
         Bank as Bank may designate. Borrower authorizes 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 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 Borrower's

                                       9
<PAGE>

         premises, Borrower hereby grants Bank a license to enter such premises
         and to occupy the same, without charge, in order to exercise any of
         Bank's rights or remedies provided herein, at law, in equity, or
         otherwise;

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

         (g) Ship, reclaim, recover, store, finish, maintain, repair, prepare
         for sale, advertise for sale, and sell (in the manner provided for
         herein) the Collateral. 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, 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, to the extent required for Bank's exercise
         of its rights under this Section 9.1, Borrower's rights under all
         licenses and all franchise agreements shall inure to Bank's benefit;

         (h) 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 Borrower's premises) as Bank
         determines is commercially reasonable, and apply the proceeds thereof
         to the Obligations in whatever manner or order it deems appropriate;
         and

         (i) Bank may credit bid and purchase at any public sale, or at any
         private sale as permitted by law.

         Any deficiency that exists after disposition of the Collateral as
provided above will be paid immediately by Borrower.

9.2 Exim Direction. Upon the occurrence of an Event of Default, Exim Bank shall
have a right to: (i) direct Bank to exercise the remedies specified in Section
9.1 and (ii) request that Bank accelerate the maturity of any other loans to
Borrower as to which Bank has a right to accelerate.

9.3 Exim Notification. Bank shall have the right to immediately notify Exim Bank
in writing if it has knowledge of the occurrence of any of the following events:
(1) any failure to pay any amount due under this Exim Agreement or the Note; (2)
the Borrowing Base is less than the sum of outstanding Advances hereunder; (3)
any failure to pay when due any amount payable to Bank by the Borrower under any
loan(s) extended by Bank to Borrower; (4) the filing of an action for debtor's
relief by, against, or on behalf of Borrower; or (5) any threatened or pending
material litigation against Borrower, or any material dispute involving
Borrower.

In the event that it sends such a notification to Exim Bank, Bank shall have the
right to thereafter send Exim Bank a written report on the status of the events
covered by said notification on each Business Day which occurs every thirty (30)
calendar days after the date of said notification, until such time as Bank files
a claim with Exim Bank or said default or other events have been cured. Bank
shall not have any obligation to make any Advances following said notification
to Exim Bank, unless Exim Bank gives its written approval thereto. If directed
to do so by Exim Bank, Bank shall have a right promptly to exercise any rights
it may have against Borrower to demand the immediate repayment of all amounts
outstanding under the Exim Loan Documents.

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

9.5 Power of Attorney. Effective only upon the occurrence and during the
continuance of an Event of Default, Borrower hereby irrevocably appoints Bank
(and any of Bank's designated officers, or employees) as Borrower's true and
lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account,

                                       10
<PAGE>

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 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 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 Borrower where permitted by law provided
Bank may exercise such power of attorney to sign the name of Borrower on any of
the documents described in Section regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

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

9.7 Bank Expenses. If 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 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 Line as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance policies
of the type discussed in Section 6.5 of the Domestic Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so paid
or deposited by 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 Bank
shall not constitute an agreement by Bank to make similar payments in the future
or a waiver by Bank of any Event of Default under this Agreement.

9.8 Bank's Liability for Collateral. So long as Bank complies with reasonable
banking practices, 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 Borrower.

9.9 Demand; Protest. 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 Bank on which Borrower may in any way be liable.

10. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER

         The laws of the Commonwealth of Massachusetts shall apply to this
Agreement. BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES,
UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE COMMONWEALTH OF MASSACHUSETTS IN ANY ACTION, SUIT,
OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES OUT OF OR BY REASON OF THIS
AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK CANNOT AVAIL ITSELF OF
THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS, BORROWER ACCEPTS JURISDICTION
OF THE COURTS AND VENUE IN SANTA CLARA COUNTY, CALIFORNIA.

         BORROWER AND BANK EACH HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE
EXIM LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR
STATUTORY CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER
CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. EACH
PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL
COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS
FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

Exim Bank Expenses in any way suffered, incurred, or paid by Bank as a result of
or in any way arising out of, following, or consequential to transactions
between Bank and Borrower whether under this Exim Agreement, or otherwise
(including without limitation reasonable attorneys fees and expenses), except
for losses caused by Bank's gross negligence or willful misconduct.

benefit of the respective successors and permitted assigns of each of the

which consent may be granted or withheld in Bank's sole discretion. Bank shall
have the right without the consent of or notice to Borrower to sell, transfer,

                            Revolving Promissory Note
                              (Export-Import Line)


$2,000,000.00     December 27, 1999

         FOR VALUE RECEIVED, the undersigned (the "Borrower"), promises to pay
to the order of Silicon Valley Bank ("Bank"), at such place as the holder hereof
may designate, in lawful money of the United States of America, the aggregate
unpaid principal amount of all advances ("Advances") made by Bank to Borrower,
up to a maximum principal amount of Two Million Dollars ($2,000,000.00), plus
interest on the aggregate unpaid principal amount of such Advances, at the rates
and in accordance with the terms of the Export-Import Bank Loan and Security
Agreement between Borrower and Bank of even date herewith, as amended from time
to time (the "Loan Agreement") on the first calendar day of each month after an
Advance has been made. The entire principal amount and all accrued interest
shall be due and payable on December 27, 2000, or on such earlier date, as
provided for in the Loan Agreement.

         Borrower irrevocably waives the right to direct the application of any
and all payments at any time hereafter received by Bank from or on behalf of
Borrower, and Borrower irrevocably agrees that Bank shall have the continuing
exclusive right to apply any and all such payments against the then due and
owing obligations of Borrower as Bank may deem advisable. In the absence of a
specific determination by Bank with respect thereto, all payments shall be
applied in the following order: (a) then due and payable fees and expenses; (b)
then due and payable interest payments and mandatory prepayments; and (c) then
due and payable principal payments and optional prepayments.

         Bank is hereby authorized by Borrower to endorse on Bank's books and
records each Advance made by Bank under this Note and the amount of each payment
or prepayment of principal of each such Advance received by Bank; it being
understood, however, that failure to make any such endorsement (or any errors in
notation) shall not affect the obligations of Borrower with respect to Advances
made hereunder, and payments of principal by Borrower shall be credited to
Borrower notwithstanding the failure to make a notation (or any errors in
notation) thereof on such books and records.

         Borrower promises to pay Bank all reasonable costs and reasonable
expenses including all reasonable attorneys' fees, incurred in such collection
or in any suit or action to collect this Note or in any appeal thereof, unless a
final court of competent jurisdiction finds that the Bank acted with gross
negligence or willful misconduct. Borrower waives presentment, demand, protest,
notice of protest, notice of dishonor, notice of nonpayment, and any and all
other notices and demands in connection with the delivery, acceptance,
performance, default or enforcement of this Note, as well as any applicable
statute of limitations. No delay by Bank in exercising any power or right
hereunder shall operate as a waiver of any power or right. Time is of the
essence as to all obligations hereunder.

         This Note is issued pursuant to the Loan Agreement, which shall govern
the rights and obligations of Borrower with respect to all obligations
hereunder.

         The law of the Commonwealth of Massachusetts shall apply to this
Agreement. BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES,
UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE COMMONWEALTH OF MASSACHUSETTS IN ANY ACTION, SUIT,
OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES OUT OF OR BY REASON OF THIS
NOTE OR THE LOAN AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK
CANNOT AVAIL ITSELF OF THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS, BORROWER
ACCEPTS JURISDICTION OF THE COURTS AND VENUE IN SANTA CLARA COUNTY, CALIFORNIA.

         BORROWER WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF ANY OF THE EXIM LOAN DOCUMENTS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. BORROWER
RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL

                                       15

INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. BORROWER REPRESENTS AND WARRANTS
THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY
AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL
COUNSEL.
