Holder is entitled to receive any payment (including any payment which may be
payable by reason of the payment of any other indebtedness of the Company being
subordinated to the payment of the Subordinated Debt) by the Company on account

assignment for the benefit of creditors or any marshalling of the assets and
liabilities of the Company or otherwise):

                  (i)   all Senior Debt shall first be entitled to be finally
and indefeasibly paid in full before the Holder is entitled to receive any
payment on account of the Subordinated Debt; and

                  (ii)  any payment or distribution in respect of the
Subordinated Debt to which the Holder would be entitled except for the
provisions of this Section 4 (including any payment that may be payable by
reason of any other Indebtedness of the Company being subordinated to the
payment of the Subordinated Debt), shall be paid by the Company, the liquidating
trustee or agent or other person making such payment or distribution directly to
the Lender or any Refinancing Lender (in the case of the Senior Debt) or if the
Senior Debt has been indefeasibly paid in full, to the holders of the other

otherwise have been entitled but for the provisions of this Section 4 shall have
been applied, pursuant to the provisions of this Section 4, to the indefeasible
payment in full of all amounts payable under the Senior Debt, then and in such
case, the Holder shall be entitled to receive from the holders of such Senior
Debt at the time outstanding any payments or distributions received by such
holders of Senior Debt in excess of the amount sufficient to pay holders of
Senior Debt all amounts payable under or in respect of the Senior Debt in full
unless the holders of Senior Debt are otherwise directed by an unstayed, final,
nonappealable order or decree made by any court of competent jurisdiction.

            (f)   Subordination Rights Not Impaired by Acts or Omissions of the
Company or Holders of Senior Debt. The Company agrees that it will not make any
payment of any

terms or is intended to or shall affect the relative rights of the Holder and
creditors of the Company other than the holders of the Senior Debt, and, except
as otherwise expressly provided herein, nothing contained herein shall prevent
the Holder from exercising all remedies otherwise permitted by applicable law
upon Default (as hereinafter defined), subject to the rights, if any, under this
Section 4 of the holders of such Senior Debt in respect of cash, property,
security or securities of the Company received upon the exercise of any such
remedy. Nothing contained in this Section 4 or in this Note shall, except during
the pendency of any dissolution, winding-up, liquidation, reorganization,
recapitalization or readjustment of the Company, affect the obligation of the
Company to make, or prevent the Company from making, at any time (except under
the circumstances described in Section 4(c)) payment of principal of or interest
on this Note.

            The failure to make a payment on account of principal of or interest
on this Note by reason of any provision of this Section 4 shall not be construed
as preventing the occurrence of an Event of Default under Section 5.

            Upon any payment or distribution of assets of the Company referred
to in this Section 4, the Holder shall be entitled to rely upon any unstayed,
final, nonappealable order or decree made by any court of competent jurisdiction
or upon any certificate of any agent or other person for the purpose of
ascertaining the persons entitled to participate in any distribution, the
holders of the Senior Debt and other Indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Section 4.

            (i)   Holder Entitled to Assume Payments Not Prohibited in Absence
of Notice. The Holder shall not at any time be charged with the knowledge of the
existence of any facts which would prohibit the making of any payment to such
Holder, unless and until the Holder shall have received written notice thereof
from the Company or one or more holders of Senior Debt or a Representative
therefor; and, prior to the receipt of any such written notice, the Holder shall
be entitled to assume conclusively that no such facts exist. Nothing contained
in this Section 4 shall limit the right of the holders of Senior Debt to recover
payments as contemplated elsewhere in this Section 4. The Holder shall be
entitled to rely on the delivery to it of a written notice by a person
representing himself or itself to be a holder of such Senior Debt (or a trustee
on behalf of, or other representative of, such holder) to establish that such
notice has been given by a holder of such Senior Debt or a trustee on behalf of
any such holder.

            (j)   Rights to Insolvency Proceedings. The Holder irrevocably
authorizes and empowers the Lender or any Refinancing Lender (or if the Senior
Debt shall have been finally and indefeasibly paid in full, the Representative)
in any proceeding defined in Section 5(a) (ii) or (iii) (an "Insolvency
Proceeding") involving or relating to the Subordinated Debt to file a proof of
claim on behalf of the Holder with respect to the Subordinated Debt if the
Holder fails to file proof of its claims prior to 10 days before the expiration
of the time period during which such claims must be submitted, to accept and
receive any payment or distribution which may be payable or deliverable at any
time upon or in respect of the Subordinated Debt in an amount not in excess of
the Lender or any Refinancing Lender's or if the Senior Debt has been
indefeasibly paid in full or any other holder of Senior Debt's portion of the
Senior Debt then outstanding and to take such other action as may be reasonably
necessary to effectuate the foregoing. The Holder

                                     - 10 -




<Page>



shall provide to the Lender or any Refinancing Lender or any applicable
Representative all information and documents reasonably necessary to present
claims or seek enforcement as aforesaid. The Holder agrees that even though it
shall retain the right to vote its claims and otherwise act in any such
Insolvency Proceedings relative to the Company (including, without limitation,
the right to vote to accept or reject any plan of partial or complete
liquidation, reorganization, arrangement, composition or extension), the Holder
shall not take any action or vote in any way so as to contest (i) the validity
or the enforceability of the Credit Agreement, the Senior Loan Documents or the
liens and security interests to the extent granted to the Lender or any
Refinancing Lender by the Company with respect to the Senior Debt or any
indebtedness held by a Refinancing Lender or any other Senior Debt, (ii) the
rights of the Lender or any Refinancing Lender established in the Credit
Agreement, the Senior Loan Documents or any security documents with respect to
such liens and security interests, or (iii) the validity or enforceability of
terms of subordination set forth herein or any agreement or instrument to the
extent evidencing or relating to the Senior Debt or any indebtedness held by a
Refinancing Lender or any other Senior Debt. The Lender, any Refinancing Lender
or other holder of Senior Debt agrees that as a condition to Holder's
obligations in this paragraph while they shall retain the right to vote such
Indebtedness and otherwise act in any such reorganization proceeding relative to
the Company (including, without limitation, the right to vote or accept or
reject any plan of partial or complete liquidation, reorganization, arrangement,
composition or extension), it shall not take any action or vote in any way so as
to contest the enforceability of this Note or any other agreement or instrument
to the extent evidencing or relating to the Subordinated Debt.

            (k)   Waiver of Consolidation. The Holder agrees that it will not at
any time insist upon, plead, or in any manner whatsoever, seek the entry of any
order or judgment, any substantive consolidation, piercing of the corporate veil
or any other order or judgment that causes an effective combination of the
assets and liabilities of the Company and any other individual, Company,
partnership or joint venture in any Insolvency Proceeding.

            (l)   Waiver. The making of loans, advances and extensions of credit
or other financial accommodations to, and the incurring of any expenses by or in
respect of the Company by the Lender, any Refinancing Lender or any other holder
of Senior Debt, and presentment, demand, protest, notice of protest, notice of
nonpayment or default and all other notices to which Holder and the Company are
or may be entitled are hereby waived (except as expressly provided for herein or
as to the Company, in the Senior Loan Documents). Holder also waives notice of,
and hereby consents to, any amendment, modification, supplement, renewal,
restatement or extensions of time of payment of or increase or decrease in the
amount of any of the Senior Debt or to the Senior Loan Documents or any
collateral therefor, the taking, exchange, surrender and releasing of collateral
therefor or guarantees now or at any time held by or available to Lender, any
Refinancing Lender or any other holder of Senior Debt for the Senior Debt or any
other person at any time liable for or in respect of the Senior Debt, the
exercise of, or refraining from the exercise of any rights against the Company
or any other obligor or any collateral therefor, the settlement, compromise or
release of, or the waiver of any default with respect to, any of the Senior
Debt, and/or the Lender's, any Refinancing Lender's or any other holder of
Senior Debt's election, in any proceeding instituted under the U.S. Bankruptcy
Code, of the application of Section 1111(b)(2) of the U.S. Bankruptcy Code. Any
of the foregoing shall not, in any manner, affect the terms hereof or impair the
obligations of Holder hereunder. All of the Senior Debt shall be deemed to have
been made or incurred in reliance upon this Section 4 of this Note.

                                     - 11 -

            (m)   Insolvency. The provisions of this Section 4 shall be
applicable both before and after the filing of any petition by or against any
Loan Party under the U.S. Bankruptcy Code and all converted or succeeding cases
in respect thereof, and all references herein to the Company shall be deemed to
apply to a trustee for such Loan Party and such Loan Party as the
debtor-in-possession. The relative rights of the Lender, the Refinancing Lender
or any other holder of Senior Debt and the Holder to repayment of the Senior
Debt and Subordinated Debt, respectively, and in or to any distributions from or
in respect of such Loan Party or any collateral or proceeds of collateral, shall
continue after the filing thereof on the same basis as prior to the date of the
petition, subject to any court order approving the financing of, or use of cash
collateral by, such Loan Party as debtor-in-possession.

            (n)   Bankruptcy Financing. If any Loan Party shall become subject
to a proceeding under the U.S. Bankruptcy Code and if Lender, the Refinancing
Lender or any other holder of Senior Debt desires to permit the use of cash
collateral or to provide financing to such Loan Party under either Section 363
or Section 364 of the U.S. Bankruptcy Code, the Holder agrees that it will not
contest the entry of the order approving such financing or use of cash
collateral.

            (o)   Miscellaneous.

                  (i)   The Holder and the Company each will, at the Company's
expense and at any time and from time to time, promptly execute and deliver all
further instruments and documents, and take all further action that may be
reasonably necessary or desirable, or that the Lender or any Refinancing Lender
or any Representative of the Senior Creditors may reasonably request, in order
to protect any right or interest granted or purported to be granted by the
provisions of this Section 4 or to enable the Lender or any Refinancing Lender
to exercise and enforce its rights and remedies hereunder.

                  (ii)  All rights and interests under this Section 4 of the
holders of the Senior Debt, the Lender or any Refinancing Lender or any other
holder of Senior Debt, and all agreements and obligations of the Holder and the
Company under this Section 4, shall remain in full force and effect irrespective
of:

                        (a)   any lack of validity or enforceability of any
Senior Loan Document or any other agreement or instrument relating thereto or to
any Senior Debt;

                        (b)   any extension, renewal, increase, supplement,
refinancing or other change in the time, manner or place of payment of, or in
any other term of, all or any of the Senior Debt or any other Senior Debt, or
any other extension, renewal or other amendment or waiver of or any consent to
any departure from any Senior Loan Document or any other agreement or instrument
relating thereto or to any other Senior Debt, including, without limitation, any
increase in obligations resulting from the extension of additional credit to any
Loan Party or any of its subsidiaries or otherwise;

                        (c)   any taking, exchange, release or non-perfection of
any other collateral, or any taking, release or amendment or waiver of or
consent to departure from any guaranty, for all or any of the Senior Debt or any
other Senior Debt;

                                     - 12 -




<Page>



                        (d)   any manner of application of collateral, or
proceeds thereof, to all or any of the Senior Debt or any other Senior Debt, or
any manner of sale or other disposition of any collateral for all or any of the
Senior Debt or any other Senior Debt, or any other assets of any Loan Party or
any of its subsidiaries;

                        (e)   any change, restructuring or termination of the
corporate structure or existence of any Loan Party or any of its subsidiaries;
or

                        (f)   any other circumstance which might otherwise
constitute a defense available to, or a discharge of, any Loan Party or a
subordinated creditor.

                  (iii) The provisions of this Section 4 shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any Senior Debt is rescinded or must otherwise be returned by the Lender or any
Refinancing Lender or any other holder of Senior Debt upon the insolvency,
bankruptcy or reorganization of any Loan Party or otherwise, all as though such
payment had not been made.

                  (iv)  The Holder and the Company each hereby waives (to the
extent each may lawfully do so) promptness, diligence, notice of acceptance and
any other notice with respect to any of the Senior Debt and this Section 4 and
any requirement that the Lender or any Refinancing Lender or any other holder of
Senior Debt protect, secure, perfect or insure any security interest or lien or
any property subject thereto or exhaust any right or take any action against the
Company or any other person or entity or any collateral.

                  (v)   No failure on the part of the Lender or any Refinancing
Lender or any other holder of Senior Debt to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies hereunder
provided are cumulative and not exclusive of any remedies provided by law.

                  (vi)  The provisions of this Section 4 constitute a continuing
agreement and shall (A) remain in full force and effect, subject to the
provisions and limitations contained in this Section 4, until all Senior Debt
shall have been finally and indefeasibly paid in full and the Lender and any
Refinancing Lender shall have no further obligation to lend or advance under the
Senior Loan Documents, (B) be binding upon the Holder and the Company and their
successors and assigns, and (C) inure to the benefit of and be enforceable by
the Lender or any Refinancing Lender, any other holder of Senior Debt and their
successors, and permitted transferees and assigns.

      5.    Events of Default

            (a)   An "Event of Default" occurs if:

                  (i)   the Company defaults in the payment of the principal or
interest of this Note when the same becomes due and payable at maturity, upon
acceleration, or otherwise, whether or not such payment shall be prohibited by
the provisions of Section 4, and such default continues for 30 days;

                  (ii)  the Company, pursuant to or within the meaning of any
Bankruptcy Law:

                        A.    commences a voluntary case or proceeding,

                        B.    consents to the entry of an order for relief
against it in an involuntary case or proceeding,

                        C.    consents to the appointment of a Custodian of it
or for all or substantially all of its property,

                        D.    makes a general assignment for the benefit of its
creditors, or

                        E.    generally is unable to pay its debts as they
become due;

                  (iii) a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that:

                        A.    is for relief against the Company in an
involuntary case or proceeding,

                        B.    appoints a Custodian of the Company or for all or
substantially all of its property, or

                        C.    orders the liquidation of the Company;

and in each case the order or decree remains unstayed and in effect for 60 days;
or

                  (iv)  the Company fails to observe or perform any covenant,
condition or agreement required on its part to be observed or performed pursuant
to Section 4 and such failure continues for a period of 30 days following notice
thereof from the Holder.

            The term "Bankruptcy Law" means Title 11, U.S. Code or any similar
federal or state law for the relief of debtors. The term "Custodian" means any
receiver, trustee, assignee, liquidator, sequestrator or similar official under
any Bankruptcy Law. For purposes of this Agreement, the term "Default" shall
mean any event or occurrence which with the passing of time, the giving of
notice, or both, could become an Event of Default.

            (b)   Interest Rate Upon Default. If an Event of Default (other than
an Event of Default specified in clause (a)(ii) or (iii) of Section 5) occurs
and is continuing, the Interest Rate on this Note shall increase by five percent
(5%) (the "Default Interest Rate"). The Default Interest Rate shall apply only
to those periods during which an Event of Default is continuing. Upon the
Company curing any Event of Default, the Default Interest Rate shall revert to
the Interest Rate. Upon an Event of Default, the Company promises to pay all
costs and expenses of collection of this Note and to pay all reasonable
attorneys' fees incurred in such collection.

            (c)   Waiver of Past Defaults. The Holders of 50% or more of the
outstanding amount of the Company's "5% Subordinated Notes" (which shall mean
this Note and any notes issued in form substantially similar to this Note on the
date hereof and all replacements and exchanges thereof) (the "Majority Holders")
may waive an existing Default or Event of Default and its consequences. Upon any
such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this Note; but
no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon.

      6.    Amendment and Waiver

            (a)   Consent Required. Any term, covenant, agreement or condition
of this Note may, with the consent of the Company, be amended or compliance
therewith may be waived (either generally or in a particular instance and either
retroactively or prospectively), if the Company shall have obtained the consent
in writing of the Majority Holders; provided that without the consent of all
holders of the Company's 5% Subordinated Notes then outstanding, no such waiver,
modification, alteration or amendment shall be effective (i) which will change
the time of payment of the principal or interest of any Note or reduce the
Principal Amount thereof, (ii) which will change the percentage of the Notes
required to consent to any such amendment, alteration or modification, or (iii)
which will change any provisions of Section 5(b) or (c), or Section 6(b). This
Note may not be amended without the consent in writing of the Lender or any
Refinancing Lender (until the Senior Debt has been finally and indefeasibly paid
in full) or, thereafter, the holders of 50% or more of the outstanding principal
amount of the outstanding Senior Debt.

            (b)   Effect of Amendment or Waiver. Any amendment or waiver shall
apply equally to the holder of the Note and shall be binding upon it, upon each
future holder of any Note and upon the Company, whether or not such Note shall
have been marked to indicate such amendment or waiver. No such amendment or
waiver shall extend to or affect any obligation not expressly amended or waived
or impair any right consequent thereon.

      7.    Change in Control Upon Certain Events.

            Upon the occurrence of a Change in Control, the Company shall, upon
the expiration of any offer to purchase or repayment or redemption of any Senior
Debt required as a result of such Change in Control, repay this Note in full at
a price equal to the Principal Amount plus all accrued and unpaid interest. For
purposes of this Section 7 the term "Change in Control" shall mean (a) any one
Person (including a "group", as such term is used in Section 13(d) of the
Exchange Act of 1934, as amended (the "Exchange Act")) other than DARR Westwood
LLC, DARR Westwood Technology Corporation and Mary Margaret Grabel, and its
affiliates, shall, directly or indirectly, own or control 50% or more of the
voting or non-voting common equity of the Company or any successor thereto, or
(b) all or substantially all of the assets of the Company or any Significant
Subsidiary (as defined herein) shall be transferred to any Person or group of
Persons (other than to the Company or any direct or indirect Subsidiary
thereof). For purposes of this Section 7, the term "Person" shall mean any
individual, partnership, Company, trust or unincorporated organization or a
government or agency or political subdivision thereof.

            (a)   Preservation of Corporate Existence; etc. Subject to paragraph
(f), the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect the corporate existence and the material
rights (charter and statutory) and franchises of the Company, and of any other
subsidiary of the Company (collectively, the "Subsidiaries"); provided, however,
that the Company shall not be required to preserve or cause to be preserved any
such material right or franchise if the board of directors of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and that the loss thereof is not, and will not be,
adverse in any material respect to the Holder, provided, further, that the
Company may merge into Westwood Computer Corporation.

            (b)   Payment of Taxes, Assessment, Charges and Claims. The Company
will and will cause the Subsidiaries to duly pay or discharge or cause to be
paid or discharged the following before they shall become delinquent: (i) all
material taxes, assessments and governmental charges levied or imposed upon the
Company or any of the Subsidiaries or upon the income, profit or property of the
Company or any of the Subsidiaries, and (ii) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a material lien
upon the property of the Company or any of the Subsidiaries; provided, however,
that the Company or any of the Subsidiaries shall not be required to pay or
discharge or cause to be paid or discharged (but shall make adequate provision
for) any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings and for
which adequate reserves have been made.

            (c)   Waiver of Stay, Extension or Usury Laws. The Company covenants
(to the extent that it may lawfully do so) that it shall not at any time insist
upon, or plead, or in any manner whatsoever claim, and shall resist any and all
efforts to be compelled to take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the
Company from paying all or any portion of the principal of and/or interest on
this Note as contemplated herein, wherever enacted, now or at any time hereafter
in force, or which may affect the covenants or the performance of this Note; and
(to the extent that it may lawfully do so) the Company hereby expressly waives
all benefit or advantage of any such law and covenants that it shall not hinder,
delay or impede the execution of any power herein granted to the Holder but
shall suffer and permit the execution of every such power as though no such law
had been enacted.

            (d)   Compliance with Laws. The Company will, and will cause the
Subsidiaries to, comply in all material respects with all applicable statutes,
regulations, orders and restrictions of the United States, any state,
municipality or other governmental division thereof, and agencies and
instrumentalities of the foregoing, in respect of the conduct of its and their
businesses and the ownership of its and their properties (including, without
limitation, applicable statutes, regulations, orders and restrictions relating
to equal employment opportunities and environmental standards and controls),
except such as are being contested in good faith that, if reasonably likely to
be determined adversely to the Company, would not have a material adverse effect
on the business of the Company.

            (e)   Limitation on Restricted Payments.

Event of Default has occurred and is continuing, (X) such payment is made for
the retirement of the Company's capital stock or Junior Indebtedness in exchange
for or out of the net proceeds of a prior or simultaneous sale of the Company's
capital stock or Junior Indebtedness or capital stock issued in connection with
such retirement which is subordinate in right of payment to this Note at least
to the extent the Junior Indebtedness or capital stock being retired is

exercise" of an option or warrant to acquire the Company's capital stock.

the requirements for such transfer are met; provided, however, that if this Note
is presented or surrendered for registration of transfer or exchange it shall be
duly endorsed or be accompanied by a written instrument of transfer in form
satisfactory to the Company duly executed by the Holder or his attorney duly
authorized in writing. The Company may charge for its out-of-pocket expenses
incurred in connection with any transfer or exchange of the Note. All transfers
of this Note (and any replacement thereof) must comply with the requirements of
Section 4 and subject to the limitations set forth in Section 14.

      10.   Replacement Notes

            If a mutilated Note is surrendered to the Company or if the Holder
of this Note presents evidence to the reasonable satisfaction of the Company
that this Note has been lost, destroyed or wrongfully taken, the Company shall
issue a replacement Note of like tenor if the requirements of the Company for
such transactions are met. An indemnity agreement may be required that is
sufficient in the reasonable judgment of the Company to protect the Company from
any loss which it may suffer. The Company may charge for its out-of-pocket

            If the Note is surrendered to the Company in settlement of a claim
as contemplated by Section 15, the Company shall issue a replacement Note of
like tenor to the Holder provided that the amount of the Note shall be reduced
by the amount of such claim. If the Holder desires to transfer a portion of the
Note to a Subsidiary in settlement of a claim as contemplated by Section 15, the
Holder shall surrender the Note to the Company, whereupon the Company shall
issue a replacement Note of like tenor to the Subsidiary in the amount of the
claim and shall issue a replacement Note of like tenor to the Holder provided
that the amount of the originally tendered Note shall be reduced by the amount
of such claim.

Company shall have any liability for any obligations of the Company under this
Note or for any claim based on, in respect or by reason of, such obligations or
their creation. The Holder by accepting this Note waives and releases all such
liability. This waiver and release are part of the consideration for the issue
of this Note.
