Dear Fellow Quality Systems Shareholder:

You may be receiving a BLUE proxy card from a dissident shareholder and a member
of your Board of Directors, Ahmed Hussein. He is attempting to elect himself and
two of his hand-picked associates to your Company's Board of Directors -
displacing other current directors.

We are independent members of your Board of Directors. Each of us has embraced
our responsibility to work in the best interests of all shareholders. We are
beholden to no individual shareholder. We believe that your interests as
shareholders are best served by re-electing the maximum number of the Company's
recommended directors to the board. Therefore, we urge you to mark, sign, date
and return the enclosed WHITE proxy card in the enclosed envelope. Your vote is
critical regardless of how many shares you own.

We think there are three key things for you to know as you consider your vote
for the 2005 Annual Meeting:

1. Your Company's business and financial performance has been outstanding. This
performance has resulted in remarkable stock appreciation: from the beginning of
FY 01 through September 1, 2005, the Company's share price has increased from a
split-adjusted $7.04 per share to $65.31; an increase of 913%.

2. Our corporate governance principles and performance are in full compliance
with all legal and stock exchange requirements and with what we believe are best
practices among U.S. public companies. Our independent directors constitute a
majority of the Board of Directors, including all of the membership of each of
the Board committees. These independent directors were chosen by a nominating
committee, itself composed entirely of independent directors. Committee
membership was thoroughly discussed and voted on by the Board of Directors as a
whole. Each Board member had one vote in this process. No more and no less. None
of our large shareholders is a member of any standing Board Committee.

3. Mr. Hussein's proxy statement contains numerous material misstatements and
omissions and should not be relied upon. Mr. Hussein's personal agenda--seeking
to regain with his colleagues a position to control, disrupt and paralyze the
operations of your Board of Directors--cannot be permitted to jeopardize the
great momentum that your Company has achieved.

Outstanding Wealth Creation

Over the past five years Quality Systems, Inc. has created substantial value for
all of our shareholders:



            Revenue grew 25% during FY 2005 and has grown 22% per year for the
            FY 2001-2005 period.

            Operating income grew 48% during FY 2005 and has grown 49% per year
            for the FY 2001-2005 period.

            Earnings per share increased 53% during FY 2005 and has grown 44%
            per year for the FY 2001-2005 period.

            The Company returned $20 million to shareholders via a $3 per
            (pre-split) share special dividend during FY 2005.

            The Company's commitment to product excellence has driven financial
            performance and has been recognized through numerous industry awards
            during the FY 2001-2005 period.

            The Company's financial performance has earned recognition from
            groups including Forbes, Fortune, Business Week and Investors
            Business Daily and inclusion on those publications' lists of the
            nation's top performing companies.

            From the beginning of FY 01 through September 1, 2005, the Company's
            share price has increased from a split adjusted $7.04 per share to
            $65.31; an increase of 913%.

This remarkable performance occurred in spite of Mr. Hussein and not because of
him or his efforts. Why would you risk disrupting our momentum by supporting Mr.
Hussein's hand-picked directors and his increased influence?

Sound and Responsible Corporate Governance

Your Board of Directors has devoted substantial energy to developing and
implementing governance principles that comply with all legal and stock exchange
norms and that compare favorably with other companies within and without our
industry.

Mr. Hussein claims that the Company's independent directors are not truly
independent. But consider the facts:

      o     Nominees William Botts, Maurice DeWald, Jonathan Javitt, Vincent
            Love and Steven Plochocki were first elected to your Board in 2004,
            having been favorably reviewed for independence and other
            qualifications by the Board's Nominating Committee at the time.

      o     These same nominees have this year been evaluated by the Board's
            Nominating Committee which has opined favorably on their
            independence and recommended their reelection.



      o     Sheldon Razin, whose independence was specifically questioned by Mr.
            Hussein, was evaluated by the Nominating Committee and additionally
            by the Company's outside counsel and was found to have met all of
            the applicable standards for independence.

      o     Mr. Hussein has attacked the independence of 100% of the independent
            directors who have served alongside Mr. Hussein on the Company's
            Board of Directors since 1999 with the exception of those that he
            himself nominated.

The independence of the Board is reflected in the reality of boardroom action,
not just on paper. Far from being controlled by Mr. Razin or anyone else, the
deliberations of the Board are detailed and thoughtful, and both Mr. Razin and
Mr. Hussein have found themselves on the short end of numerous votes. The
Company's directors stand by their review, deliberation, and assessment
processes.

Mr. Hussein's scorecard is simple on these issues. He considers those voting
with him to be independent and those voting against him to be non-independent.
But disagreeing with Mr. Hussein is no breach of good governance.

Hussein's Distortions and Inaccuracies

To document all of the misstatements and omissions in Mr. Hussein's proxy
statement would take a document longer than we have patience to write or you
have patience to read. But you can get an accurate flavor for Mr. Hussein's
casual relationship with the truth by noting the following brief examples from
his own proxy statement:

      o     Mr. Hussein takes issue with compensation packages for members of
            the management team approved during the past year without noting
            that the Board's Compensation Committee has retained three
            independent compensation consultants beginning in December 2003 to
            advise the Committee on issues related to management and director
            compensation. Each of the consultants came to the same general
            conclusion that both management and director compensation packages
            trailed what was competitive in the marketplace, in many cases by a
            wide margin. The compensation adjustments and packages implemented
            by the Company were within the parameters recommended by the most
            recent consultant work completed. Equity-related grants in
            particular were designed to be competitive and to align the
            interests of executives and Board members with those of
            shareholders. Board and management team members other than Mr.
            Hussein call this progress. Mr. Hussein alone calls it a problem.

      o     Mr. Hussein notes repeatedly that Mr. Razin has personally appointed
            members of the Board's committees. Nothing can be further from the
            truth. The Board voted to appoint the members of each such
            committee. The Board minutes clearly reflect this fact, The Board
            reviewed and approved those minutes. Mr. Hussein also read those
            minutes, yet chooses to perpetuate this fiction in a misguided
            effort to mislead you.



      o     As part of his relentless and unjustified attack on Mr. Razin, Mr.
            Hussein would have you believe that Mr. Razin was secretly involved
            in the certain contract negotiations earlier this year. He caused
            certain Board members to plan an emergency meeting based on his
            claim. The entire Board later discovered that Mr. Hussein's claim
            was completely fabricated. No emergency meeting was held, because
            there was no emergency. We are amazed and appalled that he would
            cite this example of his own malfeasance as a lapse of corporate
            governance on our part. However, it has become clear to us that Mr.
            Hussein is not bound by the restraints of truthfulness and facts.

      As directors, we have spent an inordinate amount of time dealing with Mr.
      Hussein's rude and boorish behavior, his misstatements, threats, and lack
      of preparation for Board meetings. We are unanimous in our view that
      future shareholder interests will best be served by electing the maximum
      number of the Company's recommended directors to the board.

              DON'T LET MR. HUSSEIN DERAIL THE PROGRESS THAT YOUR
             COMPANY HAS MADE - VOTE THE ENCLOSED WHITE PROXY CARD
                                     TODAY!       ----- ----- ----

As independent members of the Company's current Board of Directors, we believe
that shareholders' interests are best served by re-electing the maximum number
of the Company's recommended directors to the board. Therefore, we urge you to
mark, sign, date and return the enclosed WHITE proxy card in the enclosed
envelope. The prompt return of your WHITE proxy card will ensure that your vote
is counted. Your vote is critical regardless of how many shares you own.
