Recitals

     A. Parent, Deluxe Business Operations, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Operating Sub”), Helix Merger Corp., a Delaware corporation and wholly owned subsidiary of Operating Sub (“Sub”), and the Company are entering into an Agreement and Plan of Merger dated as of the date hereof (the “Merger Agreement”), pursuant to which Sub will merge (the “Merger”) with and into the Company and the existing stockholders of the Company will receive cash from Parent in exchange for their shares of capital stock of the Company (“Company Capital Stock”).

     B. The execution and delivery of this Agreement is a condition precedent to Parent, Operating Sub and Sub entering into the Merger Agreement.

     C. Capitalized terms used but not otherwise defined herein have the meanings ascribed to them in the Merger Agreement.

     Therefore, the parties hereby agree as follows:

     1. Voting; Proxy.

     (a) During the term of this Agreement, at each meeting of the Company’s stockholders convened, and at any adjournment or postponement thereof, to consider and vote upon the approval of the Merger Agreement and the Merger (or as a part of any such action by written consent of the stockholders in lieu of a meeting), each Stockholder agrees to vote all             shares of Company Capital Stock owned of record by such Stockholder as of the record date for the vote or written consent (including, any shares of Company Capital Stock over which the Stockholder has voting power, by contract or otherwise, except for any shares for which the Stockholder’s sole voting power results from the Stockholder having been named as proxy pursuant to any proxy solicitation conducted by the Company’s board of directors) (i) in favor of the approval and adoption of the Merger Agreement and the Merger; (ii) against approval of any proposal made in opposition to or in competition with the consummation of the Merger and the Merger Agreement; and (iii) against any other proposal or action that would, or would reasonably be expected to, prohibit or discourage the Merger.

     (b) Each Stockholder has executed and delivered to Parent an irrevocable proxy in the form of Annex B.

     (c) Each Stockholder will be present, in person or by proxy, at all meetings of stockholders of the Company so that all shares of Company Capital Stock are counted for the purposes of determining the presence of a quorum at such meetings.

     (d) This Agreement is intended to bind each Stockholder only with respect to the specific matters set forth herein, and will not prohibit a Stockholder from acting in accordance with such Stockholder’s fiduciary duties as an officer or director of the Company.

     2. No Solicitation; No Transfer.

     (a) Until the earlier of the Effective Time or the termination of this Agreement pursuant to its terms, no Stockholder will, nor will any Stockholder authorize or permit any of the Stockholder’s representatives to, and each Stockholder will instruct each such representative not to, directly or indirectly, take any actions prohibited by Section 5.3 of the Merger Agreement, as if such Stockholder were a party thereto.

     (b) During the term of this Agreement, none of the Stockholders may sell, pledge, assign, or otherwise transfer, or authorize, propose, or agree to the sale, pledge, assignment, or other transfer of, any of such Stockholder’s shares of Company Capital Stock, unless (a) at least two business days’ written notice of the proposed transfer is provided to Parent and (b) the intended transferee agrees in writing to be bound by this Agreement as if such person were such Stockholder.

     3. Representations and Warranties. Each Stockholder represents and warrants to Parent as follows:

     (a) Authority. The Stockholder has the requisite power and authority to enter into this Agreement, to perform the Stockholder’s obligations hereunder, and to consummate the transactions contemplated hereby. No other proceedings or actions on the part of the Stockholder are necessary to authorize the execution, delivery, or performance of this Agreement or the consummation of the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Stockholder and constitutes a valid and binding obligation, enforceable against the Stockholder in accordance with its terms, except as the enforceability hereof may be limited by the Enforcement Limitations.

     (b) Title; Authority to Vote Shares. The Stockholder is the sole owner of record and has sole voting power over the number of shares of Company Capital Stock set forth opposite the Stockholder’s name on Annex A, and such shares are held by the Stockholder free and clear of all Encumbrances that would limit or otherwise affect the Stockholder’s voting rights with respect to the Company Capital Stock set forth on Annex A or otherwise prevent the Stockholder from performing the Stockholder’s obligations hereunder.

     (c) Noncontravention. Neither the Stockholder’s execution and delivery of this Agreement, nor the Stockholder’s consummation of any of the transactions contemplated hereby, nor the Stockholder’s compliance with any of the provisions hereof, will violate, conflict with, or result in a breach of, or constitute a default (or an event that, with notice or lapse of time or both, would constitute a default) under, or result in the creation of any Encumbrance upon any of the Stockholder’s shares of Company Capital Stock under, any

agreement or instrument to which the Stockholder is a party or any statute, rule, regulation, judgment, order, decree, or other legal requirement applicable to the Stockholder.

     (d) Litigation. (i) There is no claim, action, proceeding, or investigation pending or, to the Stockholder’s knowledge, threatened against or relating to the Stockholder before any Governmental Authority, and (ii) the Stockholder is not subject to any outstanding order, writ, injunction, or decree, that, in the case of clause (i) or (ii), if determined adversely, would limit or otherwise affect the Stockholder’s voting rights with respect to the Company Capital Stock set forth on Annex A or otherwise prohibit the Stockholder from performing the Stockholder’s obligations hereunder.

     (e) Reliance. Each Stockholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon such Stockholder’s execution, delivery, and performance of this Agreement. Each Stockholder acknowledges that its irrevocable proxy is granted in consideration of the execution and delivery of the Merger Agreement by Parent.

     4. Termination. This Agreement shall terminate automatically and without further action on behalf of any party at the earlier of (a) the Effective Time or (b) the date and time, if any, that the Merger Agreement is terminated pursuant to its terms. In the event of a termination of this Agreement pursuant to this Section 4, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of any party, but nothing herein shall release the Stockholder for any breach of this Agreement. If this Agreement is terminated, the proxy of the Stockholder delivered under Section 1(b) hereof shall also terminate and be of no further force or effect, and Parent shall promptly return the proxy to the Stockholder.

     5. Miscellaneous.

     (a) Notices. All notices and other communications hereunder shall be in writing and shall be deemed given if delivered personally, effective when delivered, or by express courier service, effective one business day after delivery to such courier, or by telecopy, effective when transmitted and a confirmation is received, provided the same is on a business day, and, if not, on the next business day, to the parties at the following addresses (or at such other address for a party or to such other person’s attention as shall be specified by like notice):

Agreement. No delay on the part of any party in exercising any right, power or privilege hereunder will operate as a waiver thereof.

     (k) Further Assurances.
