                                 MIGRATEC, INC.

                                 PROMISSORY NOTE

$565,000.00                                                     December 1, 2000

         MigraTEC, Inc., a Delaware corporation (the "COMPANY"), hereby promises
to pay to Mercury Fund No. 1, Ltd., a Texas limited partnership (or its
successors and assigns) ("PAYEE"), the principal sum of Five Hundred Sixty-Five
Thousand Dollars ($565,000) together with interest at the rates set forth herein
(collectively, the "LOAN AMOUNT"), upon Maturity (as such term is defined
below). This Promissory Note (the "Note") represents the definitive agreement
contemplated by that certain Letter Agreement for Bridge Financing, dated
December 1, 2000, and executed by the Company and the Payee.

         Interest on this Note shall accrue at a rate per annum equal to (i)
zero percent (0%) for the first thirty (30) days following the date of this
Note; (ii) two percent (2%) for the next thirty (30) days; (iii) four percent
(4%) for the next thirty (30) days; (iv) six percent (6%) for the next thirty
(30) days; (v) eight percent (8%) for the next thirty (30) days; (vi) ten
percent (10%) for the next thirty (30) days; and (vii) four and one-half percent
(4.5%) thereafter until repaid in full. Interest shall be calculated on the
basis of a 365 day year.

         This Note shall be due and payable in full at Maturity. For purposes of
this Note, "Maturity" shall be the first to occur of (i) December 31, 2001; or
(ii) the closing of a Qualified Financing (as such term is hereinafter defined).
For purposes of this Note, a "QUALIFIED FINANCING" means the consummation by the
Company of the next equity or equity related financing which raises proceeds of
at least Two Million Dollars ($2,000,000). The funding provided pursuant to this
Note or any agreement contemplated by its Note shall not be included for
purposes of determining a Qualified Financing.

         Upon the Maturity of this Note, Payee shall be entitled to demand
immediate repayment of this Note in full or in part. Upon a Qualified Financing,
the Loan Amount shall be redeemed out of the proceeds of the Qualified
Financing; provided, however, that Payee agrees that upon such repayment of the
Loan Amount, at the request of the Company, Payee will use the proceeds of such
repayment to purchase shares of common stock, par value $.001 per share (the
"COMMON STOCK"), of the Company pursuant to the exercise of warrants issued to
Payee under that certain Note and Warrant Purchase Agreement, dated as of
January 25, 2000, among the Company, Payee and MT Partners, L.P.

         In the event that Payee demands repayment of all or a portion of this
Note, payment shall be made by wire transfer of immediately available funds on
the date due to such bank account that Payee shall designate to the Company in
writing.

         The invalidity, or unenforceability in particular circumstances, of any
provision of this Note shall not extend beyond such provision or such
circumstances and no other provision of this Note shall be affected thereby. If
the applicable law is ever judicially interpreted so as to render usurious any
amount called for under this Note or under any of the other documents
evidencing, securing or relating to this Note or any part thereof, including the
Security Agreement dated of even date hereof by and between the Company and
Payee, or contracted for, charged, taken, reserved or received with respect to
the indebtedness evidenced by this Note (the "LOAN"), then it is the Company's
and Payee's express intent that all excess amounts theretofore collected by
Payee be credited on the principal balance of this Note (or, if this Note has
been or would

thereby be paid in full, refunded to the Company), and the provisions of this
Note and the Security Agreement immediately be deemed reformed and the amounts
thereafter collectible hereunder and thereunder reduced, without the necessity
of the execution of any new document, so as to permit the recovery of the
fullest amount called for hereunder and thereunder, while complying in all
respects with the applicable law and regulations.

         The Company and each party, if any, now or hereafter liable for payment
of any sums of money payable on this Note, jointly and severally, waive
presentment and demand for payment, notice of intent to accelerate and notice of
acceleration, protest and notice of protest and nonpayment, and diligence in
collecting or bringing suit against any party liable hereon, and agree that
their liability on this Note shall not be affected by any renewal or extension
in time of payment hereof, by any indulgence, or by any release, modification,
or substitution of any security for the payment of this Note, and hereby consent
to any and all extensions, renewals, replacements, waivers, releases, or
exchanges affecting this Note and the taking, release, modification, or
substitution of any security, with or without notice and before or after
maturity.

         This Note and the Company's obligations hereunder are secured in favor
of Payee in accordance with the terms and conditions of that certain Security
Agreement between the Company and Payee, dated of even date hereof.

         This Note shall be binding upon and inure to the benefit of the
Company, its successors and assigns, and shall inure to the benefit of the
Payee, its successors and permitted assigns. In the event this Note is placed in
the hands of an attorney for collection or suit is filed hereon or if
proceedings are had in bankruptcy, receivership, reorganization, or other legal
or judicial proceedings for the collection hereof, the Company hereby agrees to
pay to the holder of this Note reasonable attorneys' fees, and shall pay all
additional reasonable costs and expenses of collection and enforcement.

         THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS SHALL GOVERN THE VALIDITY,
CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THIS NOTE WITHOUT REGARD TO
CONFLICT OF LAWS PROVISIONS WITH A FORUM AND VENUE OF DALLAS COUNTY, TEXAS.
