Gentlemen:

As a 8.15% shareholder of TransAct Technologies, Inc., it is my position to
inform the Board of Directors of TransAct that I will not support management on
the upcoming proxy. This decision was reached after careful review and
consideration of the most recent news releases on TransAct Technologies with
regard to the adverse conditions in the fourth quarter of Fiscal 1997 and the
first quarter of Fiscal 1998.

It is my belief that the Board of Directors should also consider the following:

o   A change in senior management of TransAct Technologies, Inc.

o   An increase in the Board of Directors of TransAct Technologies, Inc. to
    seven (7) in order to bring on board individuals that have a greater
    understanding of the markets being served by the company.

o   Immediately retain an investment banker that will assist in the creation of
    shareholder value, either through a sale or merger of the company.

Yours truly,

/s/ Seth

Seth M. Lukash

After reasonable inquiry and to the best of my knowledge and belief, I certify
that the information set forth in this statement is true, complete and accurate.
