Annual Shareholders Meeting

QUALITY SYSTEMS ANNOUNCES FINAL VOTING RESULTS OF ANNUAL SHAREHOLDER MEETING

Shareholders Overwhelmingly Vote to Elect Seven of Eight Company Nominees to the Board of Directors and Defeat Dissident Bylaw Proposal

IRVINE, Calif. – September 10, 2008 – Quality Systems, Inc. (Nasdaq: QSII) today confirmed that shareholders had overwhelmingly elected seven of the company’s eight Director nominees to the Quality Systems Board at its annual meeting held on September 4, 2008, based on the final certified voting results from IVS Associates, the independent inspector of elections. The final results also showed that the proposal put forth by dissident investor Ahmed Hussein to amend Quality Systems’ definition of “independent director” in its bylaws was soundly rejected by shareholders.

Elected to the Board from the company’s slate were George Bristol, Patrick Cline, Philip Kaplan, Vincent Love, Russell Pflueger, Steven Plochocki and Sheldon Razin. Dissident candidates Mr. Hussein and Murray Brennan were also elected to the Board from Mr. Hussein’s six-member slate of nominees. Quality Systems’ corporate bylaws provide for cumulative voting, which facilitated the dissidents’ election to the Board primarily based on Mr. Hussein’s 16.8% ownership in the company.

“We are very pleased to have this meeting behind us and to have received such tremendous shareholder support during the vote,” said Steven Plochocki, CEO of Quality Systems. “Together with our management team, I am looking forward to building upon our successful track record of executing on the company’s strategic plan and maximizing value for all our shareholders.”
