TERAFORCE TECHNOLOGY CORPORATION

Ladies and Gentlemen:

     This Loan Agreement (the "Loan Agreement") will serve to set forth the
terms of the financing transactions by and between TERAFORCE TECHNOLOGY
CORPORATION ("Borrower"), and BANK ONE, NA with its main office in Chicago,
Illinois ("Bank"):

     1.   CREDIT FACILITY. Subject to the terms and conditions set forth in this
Loan Agreement and the other agreements, instruments and documents evidencing,
securing, governing, guaranteeing and/or pertaining to the Loan, as hereinafter
defined (collectively, together with the Loan Agreement, referred to hereinafter
as the "Loan Documents"), Bank hereby agrees to provide to Borrower the credit
facility set forth hereinbelow (the "Credit Facility"):

     Revolving Line of Credit. Subject to the terms and conditions set forth
     herein, Bank agrees to lend to Borrower, on a revolving basis from time to
     time during the period commencing on the date hereof and continuing through
     the maturity date of the promissory note evidencing this Credit Facility
     from time to time, such amounts as Borrower may request hereunder;
     provided, however, the total principal amount outstanding at any time shall
     not exceed $1,500,000.00 (the "Revolving Line of Credit"). Subject to the
     terms and conditions hereof, Borrower may borrow, repay and reborrow
     hereunder.

All advances under the Credit Facility shall be collectively called the "Loan".
Bank reserves the right to require Borrower to give Bank not less than one (1)
business day prior notice of each requested advance under the Credit Facility,
specifying (i) the aggregate amount of such requested advance, (ii) the
requested date of such advance, and (iii) the purpose for such advance, with
such advances to be requested in a form satisfactory to Bank.

     2.   PROMISSORY NOTE. The Loan shall be evidenced by the note of even date
herewith (together with any renewals, extensions and increases thereof, the
"Note") duly executed by Borrower and payable to the order of Bank, in form and
substance acceptable to Bank. Interest on the Note shall accrue at the rate set
forth therein. The principal of and interest on the Note shall be due and
payable in accordance with the terms and conditions set forth in the Note and in
this Loan Agreement with final maturity on May 31, 2002.
<PAGE>
     3.   REPAYMENT IN THE EVENT OF A MAJOR TRANSACTION.  Upon the occurrence
of a Major Transaction, as herein defined, (a) the entire unpaid balance of
principal of the Note, together with all accrued but unpaid interest thereon,
shall become immediately due and payable without further notice, demand,
presentation, notice of dishonor, notice of intent to accelerate, notice of
acceleration, protest or notice of protest of any kind, all of which are
expressly waived by Borrower, and (b) further advances under the Note shall
cease and no further advances shall be available under this Credit Facility.
The term "Major Transaction", as used herein, shall mean net cash proceeds to
Borrower of more than $10,000,000.00 as the result of (a) the sale, transfer or
other disposition of any assets, other than in the normal course of business,
of Borrower or any subsidiary of Borrower, (b) the sale, pledge or transfer of
any subsidiary or business division of Borrower or any subsidiary of Borrower,
or (c) the settlement of litigation or collection by Borrower of a final
judgment in such litigation.

     4.   GUARANTOR.  As a condition precedent to the Bank's obligation to make
the Loan to Borrower, Borrower agrees to cause O.S. Wyatt, Jr. (the
"Guarantor") to each execute and deliver to Bank contemporaneously herewith a
guaranty agreement, in form and substance satisfactory to Bank.

     5.   REPRESENTATIONS AND WARRANTIES.  Borrower hereby represents and
warrants, and upon each request for an advance under the Credit Facility further
represents and warrants, to Bank as follows:

          (a)  Existence.  Borrower is a corporation duly organized, validly
     existing and in good standing under the laws of the State of Delaware and
     all other states where it is doing business, and has all requisite power
     and authority to execute and deliver the Loan Documents.

          (b)  Binding Obligations.  The execution, delivery, and performance of
     this Loan Agreement and all of the other Loan Documents by Borrower have
     been duly authorized by all necessary action by Borrower, and constitute
     legal, valid and binding obligations of Borrower, enforceable in accordance
     with their respective terms, except as limited by bankruptcy, insolvency or
     similar laws of general application relating to the enforcement of
     creditors' rights and except to the extent specific remedies may generally
     be limited by equitable principles.

          (c)  No Consent.  The execution, delivery and performance of this Loan
     Agreement and the other Loan Documents, and the consummation of the
     transactions contemplated hereby and thereby, do not (i) conflict with,
     result in a violation of, or constitute a default under (A) any provision
     of its articles or certificate of incorporation or bylaws, if Borrower is a
     corporation, or its partnership agreement, if Borrower is a partnership, or
     any agreement or other instrument binding upon Borrower, or (B) any law,
     governmental regulation, court decree or order applicable to Borrower, or
     (ii) require the consent, approval or authorization of any third party.

          (d)  Financial Condition.  Each financial statement of Borrower
     supplied to the Bank truly discloses and fairly presents Borrower's
     financial condition as of the date of each such statement. There has been
     no material adverse change in such financial condition or results of

                                       2

<PAGE>
     operations of Borrower subsequent to the date of the most recent financial
     statement supplied to the Bank.

          (e)  Litigation. Except as disclosed as of the date hereof in
     Borrower's filings with the Securities and Exchange Commission, there are
     no actions, suits or proceedings, pending or, to the knowledge of Borrower,
     threatened against or affecting Borrower or the properties of Borrower,
     before any court or governmental department, commission or board, which, if
     determined adversely to Borrower, would have a material adverse effect on
     the financial condition, properties, or operations of Borrower.

          (f)  Taxes: Governmental Charges. Borrower has filed all material
     federal, state and local tax reports and returns required by any law or
     regulation to be filed by it and has either duly paid all taxes, duties and
     charges indicated due on the basis of such returns and reports, or made
     adequate provision for the payment thereof, and the assessment of any
     material amount of additional taxes in excess of those paid and reported is
     not reasonably expected.

     6.   CONDITIONS PRECEDENT TO ADVANCES. Bank's obligation to make any
advance under this Loan Agreement and the other Loan Documents shall be subject
to the conditions precedent that, as of the date of such advance and after
giving effect thereto (i) all representations and warranties made to Bank in
this Loan Agreement and the other Loan Documents shall be true and correct in
all material respects, as of and as if made on such date, (ii) no material
adverse change in the financial condition of Borrower since the effective date
of the most recent financial statements furnished to Bank by Borrower shall have
occurred and be continuing, (iii) no event has occurred and is continuing, or
would result from the requested advance, which with notice or lapse of time, or
both, would constitute an Event of Default (as hereinafter defined), and (iv)
Bank's receipt of all Loan Documents appropriately executed by Borrower and all
other proper parties.

     7.   AFFIRMATIVE COVENANTS. Until (i) the Note and all other obligations
and liabilities of Borrower under this Loan Agreement and the other Loan
Documents are fully paid and satisfied, and (ii) the Bank has no further
commitment to lend hereunder, Borrower agrees and covenants that it will, unless
Bank shall otherwise consent in writing:

          (a)  Accounts and Records. Maintain its books and records in
     accordance with generally accepted accounting principles.

          (b)  Right of Inspection. Permit Bank to visit its properties and
     installations and to examine, audit and make and take away copies or
     reproductions of Borrower's books and records, at all reasonable times.

          (c)  Right to Additional Information. Furnish Bank with such
     additional information and statements, lists of assets and liabilities, tax
     returns, and other reports with respect to Borrower's financial condition
     and business operations as Bank may request from time to time.

                                       3

<PAGE>
          (d)  Compliance with Laws.  Conduct its business in an orderly and
     efficient manner consistent with good business practices, and perform and
     comply with all statutes, rules, regulations and/or ordinances imposed by
     any governmental unit upon Borrower its businesses, operations and
     properties (including without limitation, all applicable environmental
     statutes, rules, regulations and ordinances).

          (e)  Taxes.  Pay and discharge when due all of its indebtedness and
     obligations, including without limitation, all assessments, taxes,
     governmental charges, levies and liens, of every kind and nature, imposed
     upon Borrower or its properties, income, or profits, prior to the date on
     which material penalties or penalties which are not otherwise waived would
     attach, and all lawful claims that, if unpaid, might become a lien or
     charge upon any of Borrower's properties, income, or profits; provided,
     however, Borrower will not be required to pay and discharge any such
     assessment, tax, charge, levy, lien or claim so long as (i) the legality of
     the same shall be contested in good faith by appropriate judicial,
     administrative or other legal proceedings, and (ii) Borrower shall have
     established on its books adequate reserves with respect to such contested
     assessment, tax, charge, levy, lien or claim in accordance with generally
     accepted accounting principles, consistently applied.

          (f)  Insurance.  Maintain insurance, including but not limited to,
     fire insurance, comprehensive property damage, public liability, worker's
     compensation, business interruption and other insurance deemed reasonably
     necessary or otherwise reasonably required by Bank.

     incurrence or assumption by Borrower of any actual or contingent material
     liabilities not permitted under this Loan Agreement.

          (h)  Notice of Litigation.  Promptly after the commencement thereof,
     notify Bank of all actions, suits and proceedings before any court or any
     governmental department, commission or board which could reasonably be
     expected to have a material affect on Borrower or any of its properties.

          (i)  Notice of Material Adverse Change.  Promptly inform Bank of (i)
     any and all material adverse changes in Borrower's financial condition, and
     (ii) all claims made against Borrower which could materially affect the
     financial condition of Borrower.

          (j)  Additional Documentation.  Execute and deliver, or cause to be
     executed and delivered, any and all other agreements, instruments or
     documents which Bank may reasonably request in order to give effect to the
     transactions contemplated under this Loan Agreement and the other Loan
     Documents.

     8.   NEGATIVE COVENANTS.  Until (i) the Note and all other obligations and
liabilities of Borrower under this Loan Agreement and the other Loan Documents
are fully paid and satisfied, and (ii)

                                       4

presentation, notice of dishonor, notice of intent to accelerate, notice of
acceleration, protest or notice of protest of any kind, all of which are
expressly waived by Borrower, and (b) Bank may, at its option, cease further
advances under any of the Note; provided, however, concurrently and
automatically with the occurrence of an Event of Default under subparagraph (f)
in the immediately preceding paragraph (i) further advances under the Note shall
cease, and (ii) the Note and all other indebtedness owing to Bank by Borrower at
such time shall, without any action by Bank, become due and payable, without
further notice, demand, presentation, notice of dishonor, notice of
acceleration, notice of intent to accelerate, protest or notice of protest of
any kind, all of which are expressly waived by Borrower. All rights and remedies

     14.  WAIVER AND AGREEMENT. Neither the failure nor any delay on the part of
Bank to exercise any right, power or privilege herein or under any of the other
Loan Documents shall operate as a waiver thereof, nor shall any single or
partial exercise of such right, power or privilege preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. No
waiver of any provision in this Loan Agreement or in any of the other Loan
Documents and no departure by Borrower therefrom shall be effective unless the
same shall be in writing and signed by Bank, and then shall be effective only in

benefit of Bank and Borrower, and their respective successors and assigns,

Agreement or any of the other Loan Documents.
