NATION’S TWO LEADING INDEPENDENT PROXY ADVISORY FIRMS RECOMMEND VOTING FOR THE PROPOSED MERGER

Last week, ISS and Glass Lewis & Co, the nation’s two leading independent voting advisory firms, issued analyses recommending that their clients—which include thousands of institutional investors, mutual funds and pension funds—vote FOR the proposed merger with UNICOM.

In its report dated August 30, 2012, ISS concluded:

“The merger consideration provides Network Engines shareholders with a significant premium (approximately 83% as of the day before the merger was announced), and is in line with the estimated values of the fairness opinion. Furthermore, market reaction to the merger has been positive, the company conducted a thorough auction process, and there do not appear to be any material conflicts of interest. Therefore, shareholder support for the proposed merger is warranted.”(1)

The August 28th Glass Lewis report noted “…that the Company will begin to lose business from EMC that accounted for 31.9% of revenue in the quarter ended March 31, 2012 and it also received a letter from the NASDAQ that its shares closed below $1.00 for 30 consecutive business days and could eventually be delisted,”

and concluded:

“In light of these operating challenges, we believe the proposed transaction could represent a favorable exit opportunity for shareholders. In further considering the significant number of parties involved in the sale process and the relative lack of interest, we are inclined to believe the proposed consideration represents what is reasonably likely the most favorable offer available to shareholders at the present time. Taking these factors in the aggregate, along with the unanimous support of the board, we believe the proposed transaction is in the best interests of shareholders.”(2)

YOUR VOTE IS EXTREMELY IMPORTANT REGARDLESS

OF THE NUMBER OF SHARES YOU OWN
