QSI Urges Shareholders to Vote for Board Nominees Ahead of Annual Meeting

IRVINE, Calif. – August 2, 2012 – Quality Systems, Inc. (Nasdaq: QSII) announced today that Glass-Lewis, a leading voting advisory service, has recommended that QSI shareholders vote for all of the Company’s board nominees - Craig Barbarosh, George Bristol, Mark Davis, Russell Pflueger, Steven Plochocki, Sheldon Razin, Lance Rosenzweig and Maureen Spivack - at Quality Systems’ Annual Meeting of Shareholders to be held on Thursday, August 16, 2012. The endorsement follows a similar recommendation by Egan-Jones, another leading voting advisory service, which last week also urged QSI shareholders to vote the WHITE proxy card for QSI’s nominees.

In its report, Glass-Lewis noted:

“…we believe incumbent management, with access to more and better information regarding the Company, should be given the benefit of the doubt regarding strategic business decisions…

… the Company’s long-term operating and share price performance have generally matched or exceeded QSI’s most comparable peers, and we have seen no indication there is wide-spread doubt regarding the viability of the Company’s existing strategy…

…we see the Company's revenue growth rate has generally exceeded the peer median by a significant margin…

...we would take no issue with QSI’s current board structure or governance, and would find no substantive cause to withhold votes from any of the Company’s nominees...

… we find Mr. Hussein’s arguments fall closer to canard, relying heavily on hearsay to support claims of malfeasance...

…Mr. Hussein has effectively provided shareholders no financial basis upon which to justify wholesale change at the board level…

Steven T. Plochocki, chief executive officer of Quality Systems, said: “We now have endorsements from two of the leading proxy advisory services in the country and appreciate Glass-Lewis’ and Egan-Jones’ endorsement of our highly qualified board nominees for election at our upcoming annual meeting. We see meaningful opportunity ahead for QSI and continue to position the Company to seize this potential and deliver value to our shareholders. In particular, we are pleased that Glass Lewis recognized the outstanding long-term performance under our current board and management team, and its endorsement of our strategy and abilities to continue capturing opportunities for growth in this rapidly changing marketplace. We urge shareholders to vote FOR our nominees on the WHITE proxy card today.”
