Exhibit 99.2

[CSI LETTERHEAD]

April 3, 2012

Dear CSI Colleagues:

Earlier today, we issued a press release acknowledging our receipt of a non-binding letter from Constellation Software Inc. (“Constellation”) proposing to acquire all of the Company’s outstanding common and preferred stock, and outstanding options to acquire such shares, in a recommended cash tender offer at a price per share of US$1.00. Consistent with its fiduciary duties to act in the best interests of the Company and its stockholders, and in consultation with its independent financial and legal advisors, the Board of Directors of CSI will review Constellation’s proposal and respond in due course.

We realize this news has the potential to be distracting. Until the Board makes its recommendation, however, we will be constrained in what we can say and simply cannot speculate on the outcome.

You have all done a wonderful job helping to build this great Company and you are a vital part of its future. Your efforts have allowed us to provide excellent solutions and services to our customers and to remain profitable in a very tough economic environment. It is not surprising that other companies recognize what we have built and are expressing an interest in us. I encourage you to remain focused on our business and on continuing to provide first rate service to our customers.

If you receive any media or other outside inquiries regarding this situation, please direct them to the contact listed on the press release. If you have any specific questions, please feel free to contact me or David Dechant.

Thank you for your continued dedication and hard work.
