TORONTO, ONTARIO and EASLEY, SOUTH CAROLINA -- (Marketwire) -- 11/07/12 -- Constellation Software Inc. ("Constellation") (TSX:CSU) and Computer Software Innovations, Inc. ("CSWI") (OTCBB:CSWI) today jointly announced that Constellation's subsidiary, N. Harris Computer Corporation ("Harris"), has successfully completed its tender offer for the outstanding shares of common and preferred stock of CSWI.

The tender offer expired as scheduled at 12:00 midnight, New York City time, at the end of Tuesday, November 6, 2012, and was not extended. The depositary for the offer has advised Harris that as of the expiration time, a total of approximately 12,382,907 CSWI shares were validly tendered in the offer and not withdrawn (including approximately 715,684 shares delivered through notices of guaranteed delivery), representing approximately 85.6% of the outstanding common stock and 100% of the outstanding preferred stock of CSWI. All shares that have been validly tendered and not withdrawn have been accepted for purchase, and payment for such shares will be made promptly in accordance with the terms of the tender offer and merger agreement at the offer price of $1.10 per share, net to the seller in cash, without interest and less any applicable withholding taxes.

Harris expects to complete the acquisition of CSWI promptly through a "short-form" merger of a wholly-owned subsidiary with and into CSWI, with CSWI as the surviving corporation. Pursuant to the terms and conditions of the merger agreement, Harris will exercise its "top-up" option to purchase directly from CSWI an additional number of shares for $1.10 per share (the same per share price paid in the tender offer) so that Harris owns at least 90% of the outstanding shares of CSWI common stock, which will allow Harris to complete and close the merger without a vote or meeting of CSWI's stockholders through the "short-form" merger provisions of Delaware law.

In the merger, each outstanding CSWI share not tendered and purchased in the offer (other than those as to which holders properly exercise dissenters rights, if any) will be converted into the right to receive the same $1.10 per share in cash that was paid in the tender offer, without interest and less any applicable withholding taxes. As a result of the merger, CSWI will become a wholly-owned subsidiary of Harris. Following the merger, CSWI's common stock will cease to be quoted on the OTC Bulletin Board.

This press release is neither an offer to purchase nor a solicitation of an offer to sell shares of CSWI.
