Partner FAQ Document

Quest has entered into an agreement with Insight Venture Partners to take the Company private.

The Company will no longer trade on a stock exchange but will instead be owned by a small number of investors, including Insight Venture Partners and Vinny Smith, who will maintain a significant ownership interest in the Company. The company will continue to be led by Vinny Smith as Chairman & CEO and Quest’s existing senior management team.

Insight Venture Partners is a leading private equity and venture capital firm focused on the global software, Internet and data services industries. As an early investor in Quest, Insight knows our Company well and is committed to being an even more important partner going forward to help the Company achieve its strategic goals.

A Special Committee made up of independent and disinterested directors of the Quest Software Board conducted a review of the Company’s alternatives with its independent financial and legal advisors. The board determined that this transaction includes an attractive upfront premium for Quest’s stockholders in an all-cash transaction. The entire executive team is confident that this new structure will provide Quest with even greater flexibility in the marketplace as we execute our strategies to meet the needs of our customers.

Our market focus and industry direction remain unchanged. We expect to continue our track record of innovation to meet our customers’ and partner’s technological and business requirements and continue our leadership in enterprise systems management software.

We believe this agreement is a positive development for the Company, its stockholders, customers, partners and employees. We are partnering with a firm that is highly committed to Quest’s success in the marketplace. We believe this will make us even better equipped to serve our customers, and offer greater long-term opportunities for our employees. Existing management stays in place and our commitment to innovation and superior service remain core values.
