Dear Mr. Barniskis:

I am pleased to inform you that Norwest Bank Minnesota, N.A. (the "Bank") has
approved the renewal of a committed line of credit (the "Line") in the amount of
$2,500,000.00 to be offered to Check Technology Corporation (the "Borrower").
The availability of the Line is subject to the Bank's receipt of a new executed
commercial note (the "Note") and our mutual execution of this letter agreement.
The following terms and conditions shall apply to the Line:

Borrower:                     Check Technology Corporation

                              date of April 30, 2001.

Purpose:                      To finance working capital needs of the Borrower.

Interest Rate:                Norwest Base Rate, floating.

Prepayments:                  Prepayments of principal may be made at any time
                              by the Borrower without penalty; however, any
                              payments of LIBOR borrowing contracts made prior
                              to the stated contractual maturity of the contract
                              will be subject to reimbursement to the Bank for
                              reasonable redeployment costs.

Collateral:                   Unsecured, however, all current assets of Borrower
                              must remain free of liens or encumbrances.

Facility Fee:                 A facility fee of one-fifth of one percent
                              (20 basis points) per annum computed on a 360-day

                              line of credit. This fee shall be paid in arrears
                              at the end of each calendar quarter.

                   dated                      .

DEFAULT AND ACCELERATION: Borrower will be default under this Note if:
(i) the Borrower fails to pay when due any principal, interest or other amounts
due under this Note, or (ii) the Borrower fails to perform or observe any term
or covenant of this Note or any related documents or perform under any other
agreement with the Bank, or (iii) the Borrower or any subsidiary fails to
perform or observe any agreement with any other creditor that relates to
indebtedness or contingent liabilities which would allow the maturity of such
indebtedness or obligation to be accelerated, or (iv) the Borrower changes its
legal form of organization, or (v) any representation or warranty made by the
Borrower in applying for the loan evidenced by this Note is untrue in any
material respect, or (vi) a garnishment, levy or writ of attachment, or any
local, state or federal notice of tax lien or levy is served upon the Bank for
the attachment of property of the Borrower or any subsidiary that is in the
Bank's possession or for indebtedness owed

<PAGE>   5
to the Borrower or any subsidiary by the Bank, or (vii) any Guaranty given in
connection herewith may have become, in the Bank's judgment, unenforceable, or
(viii) the Bank at any time, in good faith, believes that the Borrower will not
be able to pay this Note when it is due; then or at any time thereafter unless
such default is cured the Bank may, at its option, declare all unpaid principal,
accrued interest, fees and all other amounts payable under this Note to be
immediately due and payable, without notice or demand to the Borrower, and if
this Note evidences a line of credit, terminate the line of credit without
notice to the Borrower. If, however, this Note is payable on demand, nothing
herein contained shall preclude or limit the Bank from demanding payment of this
Note at any time and for any reason, without notice.

AUTOMATIC ACCELERATION: If, with or without the Borrower's consent, a custodian,
trustee or receiver is appointed for any of the Borrower's or any subsidiary's
properties, or if a petition is filed by or against the Borrower or any
subsidiary under the United States Bankruptcy Code, or if the Borrower is
dissolved or liquidated (if an entity), or dies (if an individual), the unpaid
principal, accrued interest and all other amounts payable under this Note will
automatically become due and payable without notice or demand and, if this Note
evidences a line of credit, the line of credit will automatically terminate.

REMEDIES ON DEFAULT: If the indebtedness evidenced hereby is not paid at
maturity, whether by acceleration or otherwise, the Bank shall have all of the
rights and remedies provided by any law and/or by agreement of the Borrower,
including but not limited to all of the rights and remedies of a secured party
under the Uniform Commercial Code. Any requirement of reasonable notice mandated
by the Uniform Commercial Code shall be met if the Bank sends such a notice to
the Borrower at least ten (10) days prior to the date of sale, disposition or
other event giving rise to the required notice. The Borrower shall be liable for
any deficiency remaining after disposition of any property in which the Bank has
a security interest to secure payment of the indebtedness evidenced hereby, and
the computation of such deficiency or of the amount required to redeem such
property shall include, unless otherwise prohibited by law, reasonable
attorney's fees and legal expenses.

WAIVER: Each endorser hereof or any other party liable for the indebtedness
evidenced hereby severally waives demand, presentment, notice of dishonor and
protest of this Note, and consents to any extension or postponement of time of
its payment without limit as to the number or period thereof, to any
substitution, exchange or release of all or any part of any collateral securing
this Note, to the addition of any party hereto, and to the release or discharge
of, or suspension of any rights and remedies against, any person who may be
liable hereon for the payment of the indebtedness evidenced hereby.

AMENDMENT OR MODIFICATION OF TERMS: Any amendment or modification of this Note
must be in writing and signed by the party against whom enforcement of such
amendment or modification is sought. The Bank may change any of the repayment
terms of this Note, including extensions of time and renewals, and release or
add any party liable on this Note, or agree to the substitution or release of
any security collateralizing this Note without notifying or releasing from
liability any accommodation party, endorser, or guarantor. The Bank may suspend
or waive any rights or remedies that it may have against any person who may be
liable for its repayment.

MISCELLANEOUS: No delay on the part of the Bank in the exercise of any right or
remedy shall operate as a waiver thereof, and no single or partial exercise by
the Bank of any right or remedy shall preclude any other future exercise thereof
or the exercise of any other right or remedy. No waver or indulgence by the Bank
of any default shall be effective unless in writing and signed by the Bank, nor
shall a waiver by the Bank on one occasion be construed as a bar to, or waiver
of, any such right on any future occasion. Any reference to the Bank herein
shall be deemed to include any subsequent holder of this Note. This note is
accepted in the state where the Bank is located, and shall be governed by the
laws of the state where the Bank is located. The Borrower agrees to pay all
costs in connection with the borrowing represented by this Note or security
given, including any taxes, stamp, insurance or otherwise, payable by reason of
execution and delivery of this Note and any related documents. In the event the
Bank is required to collect this Note following its Due Date or the bankruptcy
of any maker hereof, the Borrower will pay the Bank such further amounts as
shall be sufficient to cover the costs and expenses incurred in collecting this
Note and liquidating any security or guaranties given in support hereof,
including reasonable attorney's fees and expenses required to take such actions
in any court, including any bankruptcy court.

FINANCIAL REPORTING: While any amounts are due under this Note, or the Borrower
has the right to request an advance under this Note, the Bank reserves the right
to require that the Borrower deliver to the Bank annual financial statements and
such other financial information as the Bank may request.

ARBITRATION: The Bank and Borrower agree, at the request of either party, to
submit to binding arbitration all claims, disputes and controversies whether in
tort, contract, or otherwise, except "core proceedings" under the U.S.
Bankruptcy Code arising between themselves and their respective employees,
officers, directors, attorneys, and other agents, which relate in any way
without limitation to this Note, including by way of example but not by way of
limitation the negotiation, collateralization, administration, repayment,
modification, default, termination and enforcement of the loans or credit
evidenced by this Note. Arbitration under this Agreement will be governed by the
Federal Arbitration Act (Title 9 of the United States Code), except in Colorado
where it will be governed by Colorado law, and proceed in the city where the
Bank's principal office is located, or such other location as the Bank and
Borrower may agree and shall be conducted by the American Arbitration
Association ("AAA") in accordance with the AAA's commercial arbitration rules
("AAA Rules"). Arbitration will be conducted before a single neutral arbitrator
selected in accordance with AAA Rules and who shall be an attorney who has
practiced commercial law for at least ten years. The arbitrator will determine
whether an issue is arbitratable and will give effect to applicable statutes of
limitation. Judgment upon the arbitrator's award may be entered in any court
having jurisdiction. The arbitrator has the discretion to decide, upon documents
only or with a hearing, any motion to dismiss for failure to state a claim or
any motion for summary judgment. The institution and maintenance of an action
for judicial relief or pursuit of a provisional or ancillary remedy shall not
constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief. The arbitrator will award costs and expenses in
accordance with the provisions of this Note. Discovery will be governed by the
rules of civil procedure in effect in the state where the Bank's principal
office is located. Discovery must be completed at least 20 days before the
hearing date and within 180 days of the commencement of arbitration. Each
request for an extension and all other discovery disputes will be determined by
the arbitrator upon a showing that the request is essential for the party's
presentation and that no alternative means for obtaining information are
available during the initial discovery period. This Agreement does not limit the
right of either part to (i) foreclose against real or personal property
collateral; (ii) exercise self-help remedies such as setoff or repossession; or
(iii) obtain provisional remedies such as replevin, injunctive relief,
attachment or the appointment of a receiver during the pendency or before or
after any arbitration proceeding. These exceptions do not constitute a waiver of
the right or obligation of either party to submit any dispute to arbitration,
including those arising from the exercise of these remedies.
