Mr. Paul Stephenson
Vice President of Finance and Administration
Check Technology Corporation
12500 Whitewater Drive
Minnetonka, MN.  55343-9420

Dear Paul:

I am pleased to inform you that Norwest Bank Minnesota, N.A. (the "Bank") has 
approved a committed line of credit (the "Line") in the amount of 
$2,500,000.00 to be offered to Check Technology Corporation.  The 
availability of the Line is subject to the Borrower's execution of a new 
promissory 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 (the "Borrower").

TYPE                Committed revolving line of credit.

AMOUNT              $2,500,000.00

EXPIRATION          March 31, 1998

PRICING             Borrowings, if any, will accrue interest at the Bank's 
                    base rate, payable monthly.  Additional funding choices, 
                    at the Borrower's option, will be available at a rate of 
                    1.75% over the available reserve-adjusted LIBOR or CD 
                    rate of like maturity at the date of request.

FEE                 The Borrower will pay a 0.20% per annum fee on the unused 
                    portion of the line of credit, payable quarterly in 
                    arrears.  The Borrower has the option to elect a 
                    compensating balance arrangement instead of the fee on 
                    the unused portion of the line.

                    The compensating balance arrangement requires that the 
                    Borrower maintain, in its primary Norwest depository 
                    account, average collected balances of 4% of the unused 
                    portion of the line of credit.  Please note that the 
                    compensating balances are not eligible to receive 
                    earnings credit for the purpose of offsetting Bank 
                    service charges.

COLLATERAL          Unsecured.

REPORTING           The Borrower agrees to deliver the following information 
REQUIREMENTS        to the Bank:

                         6.   Supply the Bank with such other information as 
                              the Bank may from time to time reasonably 
                              request, and permit the Bank to have access to 
                              its books, records, properties, and principal 
                              officers as it may reasonably request.

CONDITIONS PRECEDENT     Prior to the making of the first advance under the
                         Line, the Borrower shall deliver, at the Bank's
                         request, certified borrowing resolutions and an
                         incumbency certificate, duly executed by the corporate
                         secretary of the Borrower and in form and content
                         acceptable to the Bank.  Furthermore, the Bank has the
                         right to not consider any requests for advances under
                         the Line if, as of the date of such request, there
                         exists an event of default under the Note.

DEFAULT                  The Bank may declare the Line terminated and declare
                         the unpaid principal, accrued interest and all other
                         amounts payable under the Note to be immediately due
                         and payable, if the Borrower fails in the observance or
                         performance of any covenant or agreement contained
                         herein, and continuance for more than 30 days.  In
                         addition, the Note contains events of default that are
                         incorporated herein by reference.
