         1.       ACCOUNTING AND OTHER TERMS
                  --------------------------

                  (a) Borrower and Bank are parties to that certain Amended and
Restated Loan and Security Agreement dated as of the date hereof (as may be

                  (b) Borrower and Bank desire in this EXIM Agreement to set
forth their agreement with respect to a working capital facility to be
guaranteed by the EXIM Bank.

                  (c) Accounting terms not defined in this EXIM Agreement shall

following GAAP. Capitalized terms not otherwise defined in this EXIM Agreement
shall have the meanings set forth in Section 13 of the Domestic Agreement. All
other terms contained in this EXIM Agreement, unless otherwise indicated, shall
have the meaning provided by the Code to the extent such terms are defined
therein.

         2.       LOAN AND TERMS OF PAYMENT
                  -------------------------

         2.1      Promise to Pay. Borrower hereby unconditionally, jointly and
severally, promises to pay Bank the outstanding principal amount of all Credit
Extensions and accrued and unpaid interest thereon as and when due in accordance
with this EXIM Agreement.

         2.1.1    Revolving EXIM Advances.

                  (a) Availability. Subject to the terms and conditions of this
EXIM Agreement and to deduction of Reserves, Bank will make EXIM Advances to
Borrower up to the Availability Amount. Amounts borrowed under the Revolving
Line may be repaid, and prior to the Revolving Line Maturity Date, reborrowed,
subject to the applicable terms and conditions precedent herein.

                  (b) Termination; Repayment. The Revolving Line terminates on
the earlier of (i) the Revolving Line Maturity Date or (ii) the termination of
the Domestic Agreement, when the principal amount of all EXIM Advances, the
unpaid interest thereon, and all other Obligations relating to the Revolving
Line shall be immediately due and payable.

         2.1.2    Letters of Credit Sublimit.

                  (a) Letters of Credit. Subject to the terms of this EXIM
Agreement, Bank shall issue or have issued Letters of Credit for Borrower's
account. All Letters of Credit shall be in form and substance acceptable to Bank
in its sole discretion and shall be subject to the terms and conditions of
Bank's standard Application and Letter of Credit Agreement (the "Letter of
Credit Application"). Borrower agrees to reimburse Bank for all drawings made
under Letters of Credit immediately upon the date of such drawing. If, on the
Revolving Line Maturity Date, there are any outstanding Letters of Credit, then
on such date Borrower shall provide to Bank cash collateral in an amount equal
to 105% of the face amount of all such Letters of Credit plus all interest,
fees, and costs due or to become due in connection therewith (as estimated by
Bank in its good faith business judgment), to secure all of the Obligations
relating to said Letters of Credit. Borrower agrees to execute any further
documentation in connection
<PAGE>
with the Letters of Credit as Bank may reasonably request. The obligation of
Borrower to immediately reimburse Bank for drawings made under Letters of Credit
shall be absolute, unconditional, and irrevocable, and shall be performed
strictly in accordance with the terms of this EXIM Agreement, such Letters of
Credit, and the Letter of Credit Application.

                  (b) Maximum Amount. The maximum face amount of all Letters of
Credit issued hereunder, together with the aggregate amount of outstanding
Credit Extensions made pursuant to Section 2.1.1, shall not exceed the Revolving
Line.

         2.2      Overadvances. If at any time or for any reason the total of
all outstanding Credit Extensions made pursuant to this EXIM Agreement exceeds
the Availability Amount (such excess amount being an "Overadvance"), Borrower
shall immediately pay the amount of the excess to Bank, without notice or
demand. Without limiting Borrower's obligation to repay to Bank the amount of
any Overadvance, Borrower agrees to pay Bank interest on the outstanding amount
of any Overadvance, on demand, at the Default Rate.

         2.3      Payment of Interest on the Credit Extensions.

                  (a) Interest Rate; EXIM Advances. Subject to Section 2.3(b),
the principal amount outstanding under the Revolving Line shall accrue interest
at a per annum rate equal to the Prime Rate plus one and three-quarters percent
(1.75%); provided, however, that beginning with the month following the date
that Borrower provides evidence satisfactory to Bank, in its sole discretion,
that Borrower has maintained Net Income, based on the trailing three (3) month
period ending on the date of measurement, of at least One Dollar ($1.00), then,
subject to Section 2.3(b), the principal amount outstanding under the Revolving
Line shall accrue interest at a per annum rate equal to the Prime Rate plus
three-quarters percent (0.75%).

                  (b) Default Rate. Immediately upon the occurrence and during
the continuance of an Event of Default, Obligations shall bear interest at a
rate per annum which is five percentage points (5.00%) above the rate that is
otherwise applicable thereto (the "Default Rate"). Payment or acceptance of the
increased interest rate provided in this Section 2.3(b) is not a permitted
alternative to timely payment and shall not constitute a waiver of any Event of
Default or otherwise prejudice or limit any rights or remedies of Bank.

                  (c) Adjustment to Interest Rate. Changes to the interest rate
of any Credit Extension based on changes to the Prime Rate shall be effective on
the effective date of any change to the Prime Rate and to the extent of any such
change.

                  (d) 360-Day Year. Interest shall be computed on the basis of a
360-day year for the actual number of days elapsed.

                  (e) Debit of Accounts. Bank may debit the Designated Deposit
Account, for principal and interest payments or any other amounts Borrower owes
Bank when due. These debits shall not constitute a set-off.

                  (f) Payment; Interest Computation; Float Charge. Interest is
payable monthly on the last calendar day of each month. In computing interest on
the Obligations, all Payments received after 12:00 p.m. Pacific time on any day
shall be deemed received on the next Business Day. In addition, so long as any
principal or interest with respect to any Credit Extension remains outstanding,
Bank shall be entitled to charge Borrower a "float" charge in an amount equal to
three (3) Business Day's interest, at the interest rate applicable to the EXIM
Advances, on all payments received by Bank. The float charge for each month
shall be payable on the last day of the month. Bank shall not be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Bank in its reasonable business judgment, and Bank may charge
Borrower's Designated Deposit Account for the amount of any item of payment
which is returned to Bank unpaid.

         2.4      Fees. Borrower shall pay to Bank:

                  (a) Commitment Fee. A fully earned, non-refundable commitment
fee, payable in accordance with the terms and conditions of the Domestic
Agreement;

                  (b) Letter of Credit Fee. Bank's customary fees and expenses
for the issuance or renewal of Letters of Credit, upon the issuance, each
anniversary of the issuance, and the renewal of such Letter of Credit; and

                                      -2-
<PAGE>
                  (c) Bank Expenses. All Bank Expenses (including reasonable and
documented attorneys' fees and expenses for documentation and negotiation of
this EXIM Agreement) incurred through and after the Effective Date, when due.

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

         2.6      EXIM Guaranty. To facilitate the financing of Eligible EXIM
Accounts, the EXIM Bank has agreed to guarantee the EXIM Loans made under this
EXIM Agreement, pursuant to a Master Guarantee Agreement, Loan Authorization
Agreement and (to the extent applicable) Delegated Authority Letter Agreement
(collectively, the "EXIM Guaranty"). If, at any time after the EXIM Guaranty has
been entered into by Bank, for any reason other than due to any action or
inaction of Borrower under the EXIM Guaranty, (a) the EXIM Guaranty shall cease
to be in full force and effect, or (b) if the EXIM Bank declares the EXIM
Guaranty void or revokes any obligations thereunder or denies liability
thereunder, Borrower shall immediately repay all outstanding EXIM Advances
hereunder, and Borrower shall cash collateralize all issued and undrawn letters
of credit issued by Bank, if any. If, at any time after the EXIM Guaranty has
been entered into by Bank, for any reason other than as described in the
foregoing sentence, (x) the EXIM Guaranty shall cease to be in full force and
effect, or (y) the EXIM Bank declares the EXIM Guaranty void or revokes any
obligations thereunder or denies liability thereunder, any such event shall
constitute an Event of Default under this EXIM Agreement. Nothing in any
confidentiality agreement, in this EXIM Agreement or in any other agreement,
shall restrict Bank's right to make disclosures and provide information to the
EXIM Bank in connection with the EXIM Guaranty.

         2.7      EXIM Borrower Agreement. Borrower shall execute and deliver a
Borrower Agreement, in the form specified by the EXIM Bank (attached hereto as
Annex A), in favor of Bank and the EXIM Bank, together with an amendment thereto
approved by the EXIM Bank to conform certain terms of such Borrower Agreement to
the terms of this EXIM Agreement (as amended, the "EXIM Borrower Agreement").
When the EXIM Borrower Agreement is entered into by Borrower and the EXIM Bank
and delivered to Bank, this EXIM Agreement shall be subject to all of the terms
and conditions of the EXIM Borrower Agreement, all of which are hereby
incorporated herein by this reference. From and after the time Borrower and the
EXIM Bank have entered into the EXIM Borrower Agreement and delivered the same
to Bank, Borrower expressly agrees to perform all of the obligations and comply
with all of the affirmative and negative covenants and all other terms and
conditions set forth in the EXIM Borrower Agreement as though the same were
expressly set forth herein. In the event of any conflict between the terms of
the EXIM Borrower Agreement (if then in effect) and the other terms of this EXIM
Agreement, whichever terms are more restrictive shall apply. Borrower
acknowledges and agrees that it has received a copy of the Loan Authorization
Agreement which is referred to in the EXIM Borrower Agreement. If the EXIM
Borrower Agreement is entered into by Borrower and the EXIM Bank and delivered
to Bank, Borrower agrees to be bound by the terms of the Loan Authorization
Agreement, including, without limitation, by any additions or revisions made
prior to its execution on behalf of EXIM Bank. Upon the execution of the Loan
Authorization Agreement by EXIM Bank and Bank, it shall become an attachment to
the EXIM Borrower Agreement. Borrower shall reimburse Bank for all fees and all
out of pocket costs and expenses incurred by Bank with respect to the EXIM
Guaranty and the EXIM Borrower Agreement, including, without limitation, all
facility fees and usage fees, and Bank is authorized to debit any of Borrower's
deposit accounts with Bank for such fees, costs and expenses when paid by Bank.

         2.8      Withholding. Payments received by Bank from Borrower hereunder
will be made free and clear of any withholding taxes. Specifically, however, if
at any time any governmental authority, applicable law, regulation or
international agreement requires Borrower to make any such withholding or
deduction from any such payment or other sum payment hereunder to Bank, Borrower
hereby covenants and agrees that the amount due from Borrower with respect to
such payment or other sum payable hereunder will be increased to the extent
necessary to ensure that, after the making of such required withholding or
deduction, Bank receives a net sum equal to the sum which it would have received
had no withholding or deduction been required and Borrower shall pay the full
amount withheld or deducted to the relevant governmental authority. Borrower
will, upon request, furnish Bank with proof satisfactory to Bank indicating that
Borrower has made such withholding payment provided, however, that Borrower need
not make any withholding payment if the amount or validity of such withholding
payment is contested in good faith by appropriate and timely proceedings and as
to which payment in full is bonded or reserved against by Borrower. The
agreements and obligations of Borrower contained in this Section 2.8 shall
survive the termination of this Agreement.

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

         3.1      Conditions Precedent to Initial Credit Extension. Bank's
obligation to make the initial Credit Extension is subject to the condition
precedent that Bank shall have received, in form and substance satisfactory to
Bank, such documents, and completion of such other matters, as Bank may
reasonably deem necessary or appropriate, including, without limitation:

                  (a) duly executed original signatures to the Loan Documents to
which it is a party;

                  (b) the Economic Impact Certification, Loan Authorization
Notice and EXIM Bank Application Form, in each case duly executed and together
with original signatures, as applicable;

                  (c) duly executed original signatures to the completed

                  (d) a legal opinion of Borrower's counsel dated as of the

         3.2      Conditions Precedent to all Credit Extensions. Bank's
obligations to make each Credit Extension, including the initial Credit
Extension, is subject to the following:

                  (a) timely receipt of any export purchase order and an EXIM
Borrowing Base Certificate relating to the request;

                  (b) except as otherwise provided in Section 3.4, timely
receipt of an executed Transaction Report;

                  (c) the representations and warranties in Section 5 shall be
true in all material respects on the date of the Transaction Report and on the
Funding Date of each Credit Extension; provided, however, that such materiality
qualifier shall not be applicable to any representations and warranties that
already are qualified or modified by materiality in the text thereof; and
provided, further that those representations and warranties expressly referring
to a specific date shall be true, accurate and complete in all material respects
as of such date, and no Default or Event of Default shall have occurred and be
continuing or result from the Credit Extension. Each Credit Extension is
Borrower's representation and warranty on that date that the representations and
warranties in Section 5 remain true in all material respects; provided, however,
that such materiality qualifier shall not be applicable to any representations
and warranties that already are qualified or modified by materiality in the text
thereof; and provided, further, that those representations and warranties
expressly referring to a specific date shall be true, accurate and complete in
all material respects as of such date;

                  (d) in Bank's sole discretion, since the date of this EXIM
Agreement, there has not been any material impairment in the general affairs,
management, results of operation, financial condition or the prospect of
repayment of the Obligations, or there has not been any material adverse
deviation by Borrower from the most recent business plan of Borrower presented
to and accepted by Bank; and

                  (e) the EXIM Guaranty shall be in full force and effect.

         3.3      Covenant to Deliver. Borrower agrees to deliver to Bank each
item required to be delivered to Bank under this EXIM A

         3.4      greement as a condition to any Credit Extension. Borrower
expressly agrees that the extension of a Credit Extension prior to the receipt
by Bank of any such item shall not constitute a waiver by Bank of Borrower's
obligation to deliver such item, and any such extension in the absence of a
required item shall be in Bank's reasonable discretion.

         3.5      Procedures for Borrowing. Subject to the prior satisfaction of
all other applicable conditions to the making of an Advance set forth in this
EXIM Agreement, to obtain an EXIM Advance, Borrower shall notify Bank (which
notice shall be irrevocable) by electronic mail, facsimile, or telephone by
12:00 p.m. Pacific time on the Funding Date of the EXIM Advance. Together with
such notification, Borrower must promptly deliver to Bank by electronic mail or
facsimile a completed Transaction Report (if required) executed by a Responsible
Officer or his or her designee. Bank shall credit EXIM Advances to the
Designated Deposit Account. Bank may make Advances under this EXIM Agreement
based on instructions from a Responsible Officer or his or her designee or
without instructions if the Advances are necessary to meet Obligations which
have become due. Bank may rely on any telephone notice given by a person whom
Bank believes is a Responsible Officer or designee.

and products thereof. Borrower represents, warrants, and covenants that the
security interest granted herein is and shall at all times continue to be a

Permitted Liens that may have superior priority to Bank's Lien under this EXIM
Agreement). If Borrower shall acquire a commercial tort claim, Borrower shall
promptly notify Bank in a writing signed by Borrower of the general details
thereof and grant to Bank in such writing a security interest therein and in the
proceeds thereof, all upon the terms of this EXIM Agreement, with such writing
to be in form and substance reasonably satisfactory to Bank.

         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 Export-Related Accounts Receivable,

Export-Related General Intangibles is subject to and subordinate to the security
interest granted to Bank in this EXIM Agreement with respect to such
Export-Related Accounts Receivable, Export-Related Inventory and any
Export-Related General Intangibles.

         4.2      Authorization to File Financing Statements. Borrower hereby
authorizes Bank to file financing statements, without notice to Borrower, with
all appropriate jurisdictions to perfect or protect Bank's interest or rights
hereunder, including a notice that any disposition of the Collateral, by either
Borrower or any other Person, shall be deemed to violate the rights of Bank
under the Code. Such financing statements may indicate the Collateral as "all
assets of the Debtor" or words of similar effect, or as being of an equal or
lesser scope, or with greater detail, all in Bank's discretion.

         5.       REPRESENTATIONS AND WARRANTIES

below.

                  (b) All statements made and all unpaid balances appearing in
all invoices, instruments and other documents evidencing the Accounts are and

each Account shall comply in all material respects with all applicable laws and
governmental rules and regulations. Borrower has no knowledge of any actual or
imminent Insolvency Proceeding of any Account Debtor whose accounts are an
Eligible EXIM Account in any EXIM Borrowing Base Certificate. To Borrower's
knowledge, all signatures and endorsements on all documents, instruments, and
agreements relating to all Accounts are genuine, and all such documents,
instruments and agreements are legally enforceable in accordance with their
terms.

principal or interest on any Credit Extension on its due date, or (b) pay any
other Obligations within three (3) Business Days after such Obligations are due
and payable (which three (3) Business Day grace period shall not apply to
payments due on the Maturity Date). During the cure period, the failure to cure
the payment default is not an Event of Default (but no Credit Extension will be
made during the cure period);

                                       -6-
<PAGE>
         8.2      Covenant Default.

                  (a) Borrower fails or neglects to perform any obligation in 7;
or

any other term, provision, condition, covenant or agreement contained in this
EXIM Agreement or any Loan Documents, and as to any default (other than those
specified in this Section 8) under such other term, provision, condition,
covenant or agreement that can be cured, has failed to cure the 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 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 cure the default shall not be deemed an Event of Default (but no
Credit Extensions shall be made during such cure period). Grace periods provided
under this section shall not apply, among other things, to financial covenants
or any other covenants set forth in subsection (a) above;

         8.3      Insolvency. (a) Borrower is unable to pay its debts (including
trade debts) as they become due or otherwise becomes insolvent; (b) Borrower

against Borrower and not dismissed or stayed within forty-five (45) days (but no
Credit Extensions shall be made while of any of the conditions described in
clause (a) exist and/or until any Insolvency Proceeding is dismissed);

         8.4      Domestic Default. The occurrence of an Event of Default under
the Domestic Loan Documents. The terms and provisions of Sections 6.2, 6.3, 6.4,
6.5, 6.6, 6.7, 6.8, 6.9, 6.10, 6.11 and Section 7 of the Domestic Agreement
(including the cure provisions for such Sections contained in Section 8.2
thereof) are hereby incorporated by reference and shall survive the termination
of the Domestic Agreement.

         8.5      EXIM Guaranty. If the EXIM Guaranty ceases for any reason to

         9.       BANK'S RIGHTS AND REMEDIES
                  --------------------------

         9.1      Rights and Remedies. While an Event of Default occurs and
continues Bank may, without notice or demand, do any or all of the following to
the extent not prohibited by applicable law:

                  (a) declare all Obligations immediately due and payable (but
if an Event of Default described in Section 8.3 occurs all Obligations are
immediately due and payable without any action by Bank);

                  (b) stop advancing money or extending credit for Borrower's
benefit under this EXIM Agreement or under any other agreement between Borrower
and Bank;

                  (c) demand that Borrower (i) deposit cash with Bank in an
amount equal to the aggregate amount of any Letters of Credit remaining undrawn,
as collateral security for the repayment of any future drawings under such
Letters of Credit, and Borrower shall forthwith deposit and pay such amounts,
and (ii) pay in advance all Letter of Credit fees scheduled to be paid or
payable over the remaining term of any Letters of Credit;

                  (d) settle or adjust disputes and claims directly with Account
Debtors for amounts on terms and in any order that Bank considers advisable,
notify any Person owing Borrower money of Bank's security interest in such
funds, and verify the amount of such account;

                  (e) make any payments and do any acts it considers necessary
or reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Bank requests and make it
available as Bank designates. Bank may enter premises where the Collateral is
located, take and maintain possession of any part of the Collateral, and pay,
purchase, contest, or compromise any Lien which appears to be prior or superior
to its security interest and pay all expenses incurred. Borrower grants Bank a
license to enter and occupy any of its premises, without charge, to exercise any
of Bank's rights or remedies;

                  (f) apply to the Obligations any (i) balances and deposits of
Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or
the account of Borrower;

                                       -7-
<PAGE>
                  (g) ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby
granted a non-exclusive, royalty-free license or other right 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 similar property as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section, Borrower's
rights under all licenses and all franchise agreements inure to Bank's benefit;

                  (h) place a "hold" on any account maintained with Bank and/or
deliver a notice of exclusive control, any entitlement order, or other
directions or instructions pursuant to any Control Agreement or similar
agreements providing control of any Collateral;

                  (i) demand and receive possession of Borrower's Books; and

                  (j) exercise all rights and remedies available to Bank under
the Loan Documents or at law or equity, including all remedies provided under
the Code (including disposal of the Collateral pursuant to the terms thereof).

         9.2      Power of Attorney. Borrower hereby irrevocably appoints Bank
as its lawful attorney-in-fact, exercisable upon the occurrence and during the
continuance of an Event of Default, to: (a) endorse Borrower's name on any
checks or other forms of payment or security; (b) sign Borrower's name on any
invoice or bill of lading for any Account or drafts against Account Debtors; (c)
settle and adjust disputes and claims about the Accounts directly with Account
Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle,
and adjust all claims under Borrower's insurance policies; (e) pay, contest or
settle any Lien, charge, encumbrance, security interest, and adverse claim in or
to the Collateral, or any judgment based thereon, or otherwise take any action
to terminate or discharge the same; and (f) transfer the Collateral into the
name of Bank or a third party as the Code permits. Borrower hereby appoints Bank
as its lawful attorney-in-fact to sign Borrower's name on any documents
necessary to perfect or continue the perfection of Bank's security interest
regardless of whether an Event of Default has occurred until all Obligations
have been satisfied in full and Bank is under no further obligation to make
Credit Extensions hereunder. Bank's foregoing appointment as Borrower's attorney
in fact, and all of Bank's rights and powers, coupled with an interest, are
irrevocable until all Obligations have been fully repaid and performed and
Bank's obligation to provide Credit Extensions terminates.

         9.3      Accounts Collection. When an Event of Default occurs and
continues, Bank may notify any Person owing Borrower money of Bank's security
interest in the funds and verify the amount of the Account. Borrower must
collect all payments in trust for Bank and, if requested by Bank, immediately
deliver the payments to Bank in the form received from the account debtor, with
proper endorsements for deposit.

         9.4      Protective Payments. If Borrower fails to obtain the insurance
called for by Section 6.5 or fails to pay any premium thereon or fails to pay
any other amount which Borrower is obligated to pay under this EXIM Agreement or
any other Loan Document, Bank may obtain such insurance or make such payment,
and all amounts so paid by Bank are Bank Expenses and immediately due and
payable, bearing interest at the then highest applicable rate, and secured by
the Collateral. Bank will make reasonable efforts to provide Borrower with
notice of Bank obtaining such insurance at the time it is obtained or within a
reasonable time thereafter. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

         9.5      Application of Payments and Proceeds. Unless an Event of
Default has occurred and is continuing, Bank may apply any funds in its
possession, whether from Borrower account balances, payments, or proceeds
realized as the result of any collection of Accounts or other disposition of the
Collateral, first, to Bank Expenses, including without limitation, the
reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Bank in the exercise of its rights under this EXIM Agreement;
second, to the interest due upon any of the Obligations; and third, to the
principal of the Obligations and any applicable fees and other charges, in such
order as Bank shall determine in its sole discretion. Any surplus shall be paid
to Borrower or other Persons legally entitled thereto; Borrower shall remain
liable to Bank for any deficiency. If an Event of Default has occurred and is
continuing, Bank may apply any funds in its possession, whether from Borrower
account balances, payments, proceeds realized as the result of any collection of
Accounts or other disposition of the Collateral, or otherwise, to the
Obligations in such order as Bank shall determine in its sole discretion. Any
surplus shall be paid to Borrower or to other Persons legally entitled thereto;
Borrower shall remain liable to Bank for any deficiency. If Bank, in its good
faith business judgment, directly or indirectly enters into a deferred payment
or other credit transaction with any purchaser at any sale of Collateral, Bank
shall have the option, exercisable at any time, of either reducing the
Obligations by the principal amount of the purchase price or deferring the
reduction of the Obligations until the actual receipt by Bank of cash therefor.

                                       -8-
<PAGE>
         9.6      Bank's Liability for Collateral. So long as Bank complies with
reasonable banking practices regarding the safekeeping of the Collateral in the
possession or under the control of Bank, Bank shall not be liable or responsible
for: (a) the safekeeping of the Collateral; (b) any loss or damage to the
Collateral; (c) any diminution in the value of the Collateral; or (d) any act or
default of any carrier, warehouseman, bailee, or other Person. Borrower bears
all risk of loss, damage or destruction of the Collateral.

         9.7      No Waiver; Remedies Cumulative. Bank's failure, at any time or
times, to require strict performance by Borrower of any provision of this EXIM
Agreement or any other Loan Document shall not waive, affect, or diminish any
right of Bank thereafter to demand strict performance and compliance herewith or
therewith. No waiver hereunder shall be effective unless signed by Bank and then
is only effective for the specific instance and purpose for which it is given.
Bank's rights and remedies under this EXIM Agreement and the other Loan
Documents are cumulative. Bank has all rights and remedies provided under the
Code, by law, or in equity. Bank's exercise of one right or remedy is not an
election, and Bank's waiver of any Event of Default is not a continuing waiver.
Bank's delay in exercising any remedy is not a waiver, election, or
acquiescence.

         9.8      Demand Waiver. Borrower waives demand, 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 held by Bank on which
Borrower is liable.

         9.9      EXIM Direction. Upon the occurrence of an Event of Default,
EXIM Bank shall have right to (i) direct Bank to exercise the remedies specified
in Section 9.1 hereof and (ii) request that Bank accelerate the maturity of any
other loans to Borrower.

         9.10     EXIM Notification. Bank has the right to immediately notify
EXIM Bank in writing if it has knowledge of any of the following events: (1) any
failure to pay any amount due under this EXIM Agreement; (2) the EXIM Borrowing
Base is less than the sum of the outstanding Credit Extensions; (3) any failure
to pay when due any amount payable to Bank under any Loan Documents owing by
Borrower to Bank; (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.

                  If Bank sends a notice to EXIM Bank, Bank has the right to
send EXIM Bank a written report on the status of events covered by the notice
every thirty (30) days after the date of the original notification, until Bank
files a claim with EXIM Bank or the defaults have been cured (but no EXIM
Advances may be required during the cure period unless EXIM Bank gives its
written approval). If directed by EXIM Bank, Bank will have the right to
exercise any rights it may have against the Borrower to demand the immediate
repayment of all amount outstanding under the EXIM Loan Documents.

         10.      NOTICES
                  -------

         11.      CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER
                  ------------------------------------------

         Massachusetts law governs the Loan Documents without regard to
principles of conflicts of law. Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in Massachusetts; provided,
however, that nothing in this EXIM Agreement shall be deemed to operate to
preclude Bank from bringing suit or taking other legal action in any other
jurisdiction to realize on the Collateral or any other security for the
Obligations, or to enforce a judgment or other court order in favor of Bank.
Borrower expressly submits and consents in advance to such jurisdiction in any
action or suit commenced in any such court, and Borrower hereby waives any
objection that it may have based upon lack of personal jurisdiction, improper
venue, or forum non conveniens and hereby consents to the granting of such legal
or equitable relief as is deemed appropriate by such court. Borrower hereby
waives personal service of the summons, complaints, and other process issued in
such action or suit and agrees that service of such summons, complaints, and
other process may be made by registered or certified mail addressed to Borrower
at the address set forth in Section 10 of this EXIM Agreement and that service
so made shall be deemed completed upon the earlier to occur of Borrower's actual
receipt thereof or three (3) days after deposit in the U.S. mails, proper
postage prepaid. NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH HEREINABOVE,
BANK SHALL SPECIFICALLY HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST
BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK
DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO
OTHERWISE ENFORCE BANK'S RIGHTS AGAINST BORROWER OR ITS PROPERTY.

TO THE EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR
RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED
UPON THIS EXIM AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION,
INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS.

                                      -10-
<PAGE>
THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS EXIM
AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

         12.      GENERAL PROVISIONS
                  ------------------

         12.1     Termination Prior to Revolving Line Maturity Date. This EXIM
Agreement may be terminated prior to the Revolving Line Maturity Date by
Borrower, effective three (3) Business Days after written notice of termination
is given to Bank. Notwithstanding any such termination, Bank's lien and security
interest in the Collateral shall continue until Borrower fully satisfies its
Obligations. If such termination is at Borrower's election (regardless of the
existence of any Event of Default), or at Bank's election due to the occurrence
and continuance of an Event of Default, Borrower shall pay to Bank, in addition
to the payment of any other expenses or fees then-owing, a termination fee in an
amount equal to one percent (1.00%) of the Revolving Line Amount (i.e. Fifty
Thousand Dollars ($50,000)); provided that no termination fee shall be charged
if the credit facility hereunder is replaced with a new facility from another
division of Silicon Valley Bank.

         12.2     Successors and Assigns. This EXIM Agreement binds and is for
the benefit of the successors and permitted assigns of each party. Borrower may
not assign this EXIM Agreement or any rights or obligations under it without
Bank's prior written consent (which may be granted or withheld in Bank's
discretion). Bank has the right, without the consent of or notice to Borrower,
to sell, transfer, negotiate, or grant participation in all or any part of, or
any interest in, Bank's obligations, rights, and benefits under this EXIM
Agreement and the other Loan Documents.

         12.3     Indemnification. Borrower agrees to indemnify, defend and hold
Bank and EXIM Bank and each of its directors, officers, employees, agents,
attorneys, or any other Person affiliated with or representing Bank and/or EXIM
Bank (each, an "Indemnified Person") harmless against: (a) all obligations,
demands, claims, and liabilities (collectively, "Claims") asserted by any other
party in connection with the transactions contemplated by the Loan Documents;
and (b) all losses or Bank Expenses incurred, or paid by such Indemnified Person
from, following, or arising from transactions between Bank and Borrower
(including reasonable attorneys' fees and expenses), except for Claims and/or
losses directly caused by such Indemnified Person's gross negligence or willful
misconduct.

         12.4     Time of Essence. Time is of the essence for the performance of
all Obligations in this EXIM Agreement.

         12.5     Severability of Provisions. Each provision of this EXIM
Agreement is severable from every other provision in determining the
enforceability of any provision.

         12.6     Correction of Loan Documents. Bank may correct patent errors
and fill in any blanks in the Loan Documents consistent with the agreement of
the parties.

         12.7     Amendments in Writing; Integration. All amendments to this
EXIM Agreement must be in writing signed by both Bank and Borrower. This EXIM
Agreement and the Loan Documents represent the entire agreement about this
subject matter and supersede prior negotiations or agreements. All prior
agreements, understandings, representations, warranties, and negotiations
between the parties about the subject matter of this EXIM Agreement and the Loan
Documents merge into this EXIM Agreement and the Loan Documents.

         12.8     Counterparts. This EXIM Agreement may be executed in any
number of counterparts and by different parties on separate counterparts, each
of which, when executed and delivered, are an original, and all taken together,
constitute one EXIM Agreement.

         12.9     Survival. All covenants, representations and warranties made
in this EXIM Agreement continue in full force until this EXIM Agreement has
terminated pursuant to its terms and all Obligations (other than inchoate
indemnity obligations and any other obligations which, by their terms, are to
survive the termination of this EXIM Agreement) have been satisfied. The
obligation of Borrower in Section 12.3 to indemnify Bank shall survive until the
statute of limitations with respect to such claim or cause of action shall have
run.

         12.10    Confidentiality. In handling any confidential information,
Bank shall exercise the same degree of care that it exercises for its own
proprietary information, but disclosure of information may be made: (a) to
Bank's Subsidiaries or Affiliates; (b) to prospective transferees or purchasers
of any interest in the Credit Extensions (provided, however, Bank shall use
commercially reasonable efforts to obtain any prospective transferee's or
purchaser's agreement to the terms of this provision that any prospective
transferee or purchaser shall have entered

                                      -11-
<PAGE>
into an agreement containing provisions substantially the same as those in this
Section 12.9); (c) as required by law, regulation, subpoena, or other order; (d)
to Bank's regulators or as otherwise required in connection with Bank's
examination or audit; (e) as Bank considers appropriate in exercising remedies
under the EXIM Loan Documents; and (f) to third-party service providers of Bank
so long as such service providers have executed a confidentiality agreement with
Bank with terms no less restrictive than those contained herein. Confidential
information does not include information that is either: (i) is in the public
domain or in Bank's possession when disclosed to Bank, or becomes part of the
public domain after disclosure to Bank; or (ii) is disclosed to Bank by a third
party, if Bank does not know that the third party is prohibited from disclosing
the information.

         12.11    Borrower Liability. Either Borrower may, acting singly,
request Credit Extensions hereunder. Each Borrower hereby appoints the other as
agent for the other for all purposes hereunder, including with respect to
requesting Credit Extensions hereunder. Each Borrower hereunder shall be jointly
and severally obligated to repay all Credit Extensions made hereunder,
regardless of which Borrower actually receives said Credit Extension, as if each
Borrower hereunder directly received all Credit Extensions. Each Borrower waives
any suretyship defenses available to it under the Code or any other applicable
law. Each Borrower waives any right to require Bank to: (i) proceed against any
Borrower or any other Person; (ii) proceed against or exhaust any security; or
(iii) pursue any other remedy. Bank may exercise or not exercise any right or
remedy it has against any Borrower or any security it holds (including the right
to foreclose by judicial or non-judicial sale) without affecting any Borrower's
liability hereunder. Notwithstanding any other provision of this EXIM Agreement
or any other Loan Document, each Borrower irrevocably waives all rights that it
may have at law or in equity (including, without limitation, any law subrogating
Borrower to the rights of Bank under this EXIM Agreement) to seek contribution,
indemnification or any other form of reimbursement from any other Borrower, or
any other Person now or hereafter primarily or secondarily liable for any of the
Obligations, for any payment made by Borrower with respect to the Obligations in
connection with this EXIM Agreement, any other Loan Document or otherwise and
all rights that it might have to benefit from, or to participate in, any
security for the Obligations as a result of any payment made by Borrower with
respect to the Obligations in connection with this EXIM Agreement or otherwise
but only until such time as the Bank has been paid in full. Any agreement
providing for indemnification, reimbursement or any other arrangement prohibited
under this Section 12.11 shall be null and void. If any payment is made to a
Borrower in contravention of this Section 12.11, such Borrower shall hold such
payment in trust for Bank and such payment shall be promptly delivered to Bank
for application to the Obligations, whether matured or unmatured.

         12.12    Right of Set Off. Borrower hereby grants to Bank, a lien,
security interest and right of set off as security for all Obligations to Bank,
whether now existing or hereafter arising upon and against all deposits,
credits, collateral and property, now or hereafter in the possession, custody,
safekeeping or control of Bank or any entity under the control of Bank
(including a Bank subsidiary) or in transit to any of them. At any time after
the occurrence and during the continuance of an Event of Default, without demand
or notice, Bank may set off the same or any part thereof and apply the same to
any liability or obligation of Borrower even though unmatured and regardless of
the adequacy of any other collateral securing the Obligations. ANY AND ALL
RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY
OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF
SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE
HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

         12.13    EXIM Borrower Agreement; Cross-Collateralization;
Cross-Default; Conflicts. Both this EXIM Agreement and the EXIM Borrower
Agreement shall continue in full force and effect, and all rights and remedies
under this EXIM Agreement and the EXIM Borrower Agreement are cumulative. The
term "Obligations" as used in this EXIM Agreement and in the EXIM Borrower
Agreement shall include without limitation the obligation to pay when due all
loans made pursuant to the EXIM Borrower Agreement (the "EXIM Loans") and all
interest thereon and the obligation to pay when due all EXIM Advances made
pursuant to the terms of this EXIM Agreement and all interest thereon. Without
limiting the generality of the foregoing, the security interest granted herein
covering all "Collateral" as defined in this EXIM Agreement and as defined in
the EXIM Borrower Agreement shall secure all EXIM Loans and all EXIM Advances
and all interest thereon, and all other Obligations. Any Event of Default under
this EXIM Agreement shall also constitute a default under the EXIM Borrower
Agreement, and any default under the EXIM Borrower Agreement shall also
constitute an Event of Default under this EXIM Agreement. In the event Bank
assigns its rights under this EXIM Agreement and/or under any note evidencing
EXIM Loans and/or its rights under the EXIM Borrower Agreement and/or under any
note evidencing Advances, to any third party, including, without limitation, the
EXIM Bank, whether before or after the occurrence of any Event of Default, Bank
shall have the right (but not any obligation), in its sole discretion, to
allocate and apportion Collateral to the EXIM Borrower Agreement and/or note
assigned and to specify the priorities of the respective security interests in
such Collateral between itself and the assignee, all without notice to or
consent of the Borrower. Should any term of the EXIM Agreement conflict with any
term of the EXIM Borrower Agreement, the more restrictive term in either
agreement shall govern Borrower.

              COMPENSATION & SUBSCRIPTION AGREEMENT

             

        THE SECURITIES BEING ACQUIRED BY YOU HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE STATE BLUE SKY OR SECURITIES LAWS AND ARE OFFERED UNDER AN EXEMPTION FROM THE REGISTRATION PROVISIONS OF SUCH LAWS. THESE SECURITIES CANNOT BE SOLD, TRANSFERRED, ASSIGNED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH THE RESTRICTIONS ON TRANSFER
        CONTAINED IN THIS STOCK SUBSCRIPTION AGREEMENT AND APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

         

             This Compensation & Subscription Agreement is entered for the purpose of you, _________________Inc., (“You”) acquiring _____________ shares of the common stock (the "Securities") of Disaboom, Inc. a Colorado corporation (“Disaboom”) from Disaboom which such Securities being issued to You in lieu of receiving a portion of the salary due and owing. 

          

             A.      Notwithstanding any other agreement between the parties, ____________ agrees that in lieu of receiving $_____ of his or her salary (the “Compensation”) for the period ending ___________, 2009 he or she will be issued __________ shares of restricted Company common stock. You agree and
        acknowledge that the shares of restricted common stock represent the full and complete payment for the Compensation you have elected to receive in the form of restricted stock. Upon issuance of the Securities You agree and acknowledge that the Compensation has been paid in full and no amount is due and owing from Disaboom. 

          

             B.      In connection with your acquisition of the Securities, you represent and warrant to Disaboom as follows:

        

        a.          You have been provided, and have reviewed all available reports filed by Disaboom pursuant to the Securities Exchange Act of 1934, including (without limitation) Disaboom' annual report on Form 10-K for the most recently-completed fiscal year
        and all Forms 10-Q for the quarters subsequent to the end of the most recent fiscal year, and such other information as you may have requested of Disaboom regarding its business, operations, management, and financial condition (all of which is referred to herein as the "Available Information").

        

        b.          You have consulted with such advisors with regard to the advisability of this transaction to the extent you have deemed such consultation to be appropriate. You acknowledge that Disaboom has advised you that it recommends that you obtain such
        advice and consultation.

        

        c.          You are aware that the Securities are not being registered under the Securities Act of 1933, as amended (the “1933Act”). You understand that the Securities are being issued in reliance on the exemption from registration provided by
        Section 4(2) thereunder. You understand that You may be required to bear the economic risk of this investment for an indefinite period of time and the Securities cannot be resold or otherwise transferred unless applicable federal and state securities laws are complied with or exemptions therefrom are available.

         

        
            

        

         

        

        d.          You acknowledge that an investment in Disaboom constitutes a high degree of risk, and there can be no assurance that any portion of your investment will be returned to you at any time. By executing this Subscription Agreement, you acknowledge
        that you understand the risks involved (including those risks identified in Disaboom’s annual and quarterly reports filed with the Securities and Exchange Commission) and are willing and able to withstand the possible complete loss of your investment.

        

        e.          You understand that the future conduct of Disaboom’s business is dependent upon a number of factors and there is no assurance that Disaboom will be able to conduct its operations as contemplated in this agreement or in any other
        information given to you.

        

        f.          The Securities are being acquired by you for your own account and not on behalf of any other person or entity. Your present financial condition is such that it is unlikely that it would be necessary for you to dispose of any portion of the
        Securities in the foreseeable future.

        

        g.          You understand that the Securities being acquired hereby have not been registered under the 1933 Act or any state or foreign securities laws, and are and will continue to be restricted securities within the meaning of Rule 144 of the General
        Rules and Regulations under the 1933 Act and applicable state statutes, and consents to the placement of an appropriate restrictive legend or legends on any certificates evidencing the Securities and any certificates issued in replacement or exchange therefor and acknowledges that Disaboom will cause its stock transfer records to note such restrictions.

        

        h.          By your signature below, you acknowledge and understand that Disaboom is relying upon the accuracy and completeness hereof in complying with certain obligations under applicable securities laws.

        

             C.     This Subscription Agreement binds and inures to the benefit of the representatives, successors and permitted assigns of the respective parties hereto.

          

             D.     You acknowledge that the issuance to you of these shares will result in tax consequences to you personally, and that you have reviewed these potential tax consequences with your personal advisors to the extent you have deemed such to be appropriate or necessary. You acknowledge and agree that Disaboom has, at your request, made no withholding whatsoever with respect to these shares for the payment of taxes. As such, you will
        be solely responsible for the payment of any and all taxes and fees that may result from your acceptance of these shares.

         

        
            

        

         

        

          

             E.     The parties to this Agreement hereby agree to execute and deliver all such further documents and instruments and do all acts and things as may be necessary or convenient to carry out the full intent and meaning of and to effect the transactions contemplated by this Agreement.

         

        Disaboom,
        Inc.                                                                                             
        Employee
