                                       4


                                                                  CONFORMED COPY

                                    AGREEMENT

      This AGREEMENT (this "Agreement"), dated as of March 19, 1998, is by and
between Seth M. Lukash ("Mr. Lukash") and TransAct Technologies Incorporated, a
Delaware corporation (the "Company").

      WHEREAS, Mr. Lukash owns 525,319 shares of the common stock, par value
$.01 per share, of the Company (the "Common Stock"), representing approximately
8.15% of the outstanding shares of Common Stock;

      WHEREAS, Mr. Lukash and the Company have had certain publicly-disclosed
disagreements regarding the conduct of the Company's business which have had an
adverse impact on the Company and the price of the Common Stock, including the
shares of Common Stock held by Mr. Lukash, and the parties wish to resolve those
disagreements in a mutually satisfactory manner;

      WHEREAS, Mr. Lukash and the Company wish to agree upon certain matters
relating to, among other things, the voting of shares of Common Stock by Mr.
Lukash;

      NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants hereinafter set forth, Mr. Lukash and the Company
hereby agree as follows:

      1. Standstill. Mr. Lukash agrees that, between the date hereof and March
31, 1999, neither Mr. Lukash nor any of his "affiliates" or "associates" (as
such terms are defined in Rule 12b-2 promulgated under the Securities Exchange
Act of 1934, as amended (the "Exchange Act")), nor any of his agents or
representatives, will, without the prior written consent of the Company or its
Board of Directors (the "Board of Directors"): (i) make, or in any way
participate in, directly or indirectly, any "solicitation" of "proxies" (as such
terms are used in the rules of the Securities and Exchange Commission) to vote,
or seek to advise or influence any person or entity with respect to the voting
of, any voting securities of the Company; (ii) make or submit a proposal or
offer (with or without conditions) with respect to any extraordinary transaction
involving the Company or its securities or assets: (iii) form, join or in any
way participate in a "group" (as defined in Section 13(d)(3) of the Exchange
Act) in connection with any of the foregoing; (iv) otherwise act or seek to
control or influence the management, Board of Directors or policies of the
Company, provided that nothing contained herein shall be deemed to prohibit Mr.
Lukash from engaging in reasonable communications with the Board of Directors on
a reasonably periodic basis; (v) disclose any intention, plan or arrangement, or
enter into any agreement, inconsistent with the foregoing; (vi) take any action
to encourage or solicit a person to propose, or to make a public announcement
regarding the possibility of, a business combination or merger involving the
Company; or (vii) make any news release, or make or participate in making any
other public announcement, publication, written statement or remarks in a public
forum by himself or any other party, relating to the Company, its subsidiaries,
its customers, its personnel or its stockholders. Mr. Lukash will promptly
advise the Company of 


                                       5


any inquiry or proposal made to him or any of his affiliates or representatives
with respect to any of the foregoing.

      2. Voting Agreement. Mr. Lukash agrees that, between the date hereof and
March 31, 1999, provided that none of non-employee members of the Board of
Directors as of the date hereof shall have ceased to be directors of the
Company, at any meeting of the stockholders of the Company, however called, and
in any action by consent of the stockholders of the Company, Mr. Lukash will
vote (or cause to be voted) any shares of Common Stock held by him (i) in favor
of any nominees as directors nominated by or on behalf of the Board of Directors
and (ii) in accordance with the recommendation of the Board of Directors on any
action, proposal or resolution that is submitted to a vote of the stockholders
of the Company with regard to the authorization of additional shares of Common
Stock to be granted pursuant to the Company's 1996 Stock Plan, provided that
such number of additional shares does not exceed the number recommended by the
Hay Group or a comparable recognized authority on compensation matters. Mr.
Lukash shall not enter into any agreement or understanding with any person or
entity to vote his shares of Common Stock or give instructions in any manner
inconsistent with this paragraph.

      3. Irrevocable Proxy. If, and only if, Mr. Lukash fails to comply with the
provisions of the preceding paragraph (as determined by the Company), Mr. Lukash
hereby agrees that such failure shall result, without any further action by him,
in the irrevocable appointment of Thomas R. Schwarz, the current Chairman of the
Board of Directors, as Mr. Lukash's attorney and proxy pursuant to the
provisions of Section 212(c) of the General Corporation Law of the State of
Delaware, with full power of substitution, to vote and otherwise act (by written
consent or otherwise) with respect to such shares at any meeting of stockholders
of the Company (whether annual or special and whether or not an adjourned or
postponed meeting) or in any consent in lieu of any such meeting or otherwise.
THIS PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED WITH AN INTEREST.
Mr. Lukash hereby revokes all other proxies and powers of attorney with respect
to shares of Common Stock owned by him that may have heretofore been appointed
or granted, and no subsequent proxy or power of attorney shall be given or
written consent executed (and if given or executed, shall not be effective) by
Mr. Lukash with respect to any shares of Common Stock. All authority herein
conferred or agreed to be conferred shall survive the death or incapacity of Mr.
Lukash and any obligation of Mr. Lukash under this Agreement shall be binding
upon his heirs, personal representatives, successors and assigns.

      4. Legal Remedies. (a) Mr. Lukash agrees that irreparable damage would
occur in the event any of his covenants under this Agreement was not performed
in accordance with the terms hereof and that it is not possible for the parties
to quantify the amount of damages that the Company may incur in the event of any
such breach by Mr. Lukash. Accordingly, the parties agree that in the event of
any such breach by Mr. Lukash, the Company shall be entitled, in addition to any
other remedies to which the Company may be entitled at law or in equity or
pursuant to any other provision of this Agreement, to specific performance of
the terms hereof. Mr. Lukash hereby agrees, to the extent permitted by
applicable law, to waive the defense in any action for specific performance that
a remedy at law would be adequate and to waive any requirement for the securing
or posting of any bond in connection with such remedy.


                                       6


      (b) Without limiting the generality of the foregoing, and in addition to
any other remedies to which the Company may be entitled at law or in equity or
pursuant to any other provision of this Agreement (but without duplication of
damages), in the event any breach of this Agreement by Mr. Lukash is, in the
judgment of the Board of Directors, a willful and material breach, the Board of
Directors may invoke the provisions of this paragraph 4(b). The Board of
Directors shall notify Mr. Lukash in writing of its determination that there has
been a willful and material breach, and shall include in its written notice a
statement of the facts constituting the alleged breach and the name of an
arbitrator designated by it (the "Company's Arbitrator"). Within three (3)
business days after his receipt of such written notice, Mr. Lukash shall
designate a second arbitrator ("Mr. Lukash's Arbitrator") by written notice to
the Board of Directors, but if he shall fail to do so within such period the
Board of Directors may designate Mr. Lukash's Arbitrator on his behalf. The
Company's Arbitrator and Mr. Lukash's Arbitrator shall attempt to agree on a
third arbitrator (the "Independent Arbitrator"), but if they are unable to do so
within three (3) business days after the designation of Mr. Lukash's Arbitrator,
then either the Company's Arbitrator or Mr. Lukash's Arbitrator may apply to the
American Arbitration Association for the selection of the Independent Arbitrator
in accordance with the Commercial Arbitration Rules of such Association. The
arbitration panel, consisting of the Company's Arbitrator, Mr. Lukash's
Arbitrator and the Independent Arbitrator (collectively, the "Arbitral Panel"),
shall conduct its proceedings in the City of New York. Within three (3) business
days after the selection of the Independent Arbitrator, the Board of Directors
shall deliver its written statement regarding the alleged breach to the Arbitral
Panel and to Mr. Lukash. Within six (6) business days after the selection of the
Independent Arbitrator, Mr. Lukash shall deliver his written response to the
Arbitral Panel and the Board of Directors. Within ten (10) business days after
the selection of the Independent Arbitrator, each of the Board of Directors and
Mr. Lukash shall present an oral summation of its position to the Arbitral Panel
in the presence of the other party. The Arbitral Panel shall issue its award
(the "Award") no later than fifteen (15) business days after the selection of
the Independent Arbitrator. The Award must be signed by not less than two
members of the Arbitral Panel. The Award shall be in writing and in the event
the Arbitral Panel determines that Mr. Lukash committed a willful and material
breach of this Agreement, he shall pay the Company damages in the amount of
$25,000 for any such breach, plus the Company's attorneys' fees and expenses
incurred in connection with the enforcement of its rights under this Agreement
and the fees and expenses of the Independent Arbitrator, to be paid in cash not
less than two (2) business days after the rendering of the Award. The Award
shall be final and binding upon the parties hereto and judgment may be entered
thereon in any court of competent jurisdiction. Except as otherwise provided
above, the fees and expenses of the Independent Arbitrator shall be borne
equally by the Company and Mr. Lukash. For purposes of this Agreement, the term
"business day" means any day that is not a Saturday, a Sunday or other day on
which banks are required or authorized by law to be closed in the City of New
York.

      5. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware without regard to the
conflicts of law principles thereof.


                                       7


      6. Counterparts. This Agreement may be executed and delivered (including
by facsimile transmission) in one or more counterparts, and by the different
parties hereto in separate counterparts, each of which when executed and
delivered shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement.

      7. Entire Agreement. This Agreement constitutes the entire agreement
between the parties with respect to the subject matter hereof and supersedes all
prior agreements and understandings between the parties with respect thereto. No
addition to or modification of any provision of this Agreement shall be binding
upon any party hereto unless made in writing and signed by all parties hereto.

      IN WITNESS WHEREOF, Mr. Lukash and the Company have executed this
Agreement as of the date first above written.
