QUALITY SYSTEMS, INC. NAMES STEVEN T. PLOCHOCKI PRESIDENT AND CHIEF EXECUTIVE OFFICER

Veteran Healthcare Executive Brings Extensive Industry Experience and Knowledge of Quality Systems to His New Post

IRVINE, Calif – August 12, 2008 – Quality Systems, Inc. (NASDAQ: QSII) today announced it has appointed Steven T. Plochocki as President and Chief Executive Officer of the company effective August 16, 2008. In addition to his distinguished career in the healthcare sector, Mr. Plochocki has served on the Board of Directors of Quality Systems since 2004, giving him insight into the company, its operations and its growth strategy. As a member of Quality Systems' management team, Mr. Plochocki will be a non-independent director and accordingly has resigned from the company's Audit Committee, Compensation Committee and the Independent Directors’ Compensation Committee. Mr. Plochocki replaces Louis Silverman, who announced in June his intention to step down as CEO.

Mr. Plochocki, 56, has worked in the healthcare industry virtually his entire professional career and served as CEO of four companies, two of which were publicly traded. Mr. Plochocki has a proven history of guiding small and mid-market companies through a variety of economic cycles while building value for their shareholders. He most recently served as Chairman and CEO of Omniflight Helicopters, Inc., the second-largest air medical services provider in the country, where he oversaw a restructuring of the company’s operations and achieved 20% EBITDA margins that ranked among the sector’s best. He also has significant experience working within healthcare product and service companies, having run operations at a $50 million healthcare billing company, Centratex, as well as at Apria Healthcare, the nation’s largest home healthcare company and at Apria’s predecessor, Abbey Healthcare Group, a $450 million home healthcare company which merged with Homedco Group to form Apria. During his tenure at InSight Health Services Corp., the nation’s largest provider of diagnostic imaging services, the company doubled in size and its share price increased by nearly 250%.

“I am thrilled to be joining Quality Systems in this new capacity, particularly after having spent the last four years watching this company successfully execute on its strategic vision and grow into the market leader,” said Mr. Plochocki. “Quality Systems has established considerable momentum and I believe this company has the vision and a solid strategic plan to continue providing attractive returns to our shareholders while providing the industry’s finest management and electronic records products and services. I look forward to partnering with NextGen’s Patrick Cline and QSI’s Donn Neufeld in this effort and am eager to get started.”

Sheldon Razin, Chairman of the Board of Quality Systems, said, “Steve brings considerable experience and leadership to this company and is well-qualified to guide Quality Systems through the next chapter of its growth. As a Board member, he has

offered insightful perspective about the industry and has been an engaged, committed member of our team. Steve understands our company, believes in its potential and possesses the ideal balance of management expertise and sector experience to take this company to new heights.”

Patrick Cline, President of the company’s NextGen Healthcare subsidiary, said “I look forward to working with Steve to take the company to its next level of growth. We both share a common belief in this company’s potential to continue to capitalize on our strong position in this dynamic and rapidly growing market.”

Mr. Plochocki has received numerous industry accolades, including being the only executive to win two national American Business Awards for best business turnarounds. He also received the Ernst & Young Entrepreneur of The Year award in the health services category in 2002. He holds an M.B.A. from Central Michigan University and currently lives in Orange County, CA.
