                                 PROXY STATEMENT

                                   ----------

                             SOLICITATION OF PROXIES

      The accompanying proxy is solicited by the Board of Directors of Quality
Systems, Inc. (the "Company") for use at the Company's Annual Meeting of
Shareholders to be held at Marriott Irvine, 18000 Von Karman Ave, Irvine,
California , on September 24, 2003 at 1:00 P.M. Pacific Time, and at any and all
adjournments thereof. All shares represented by each properly executed and
unrevoked proxy received in advance of the Annual Meeting will be voted in the
manner specified therein.

      Any shareholder has the power to revoke his or her proxy at any time
before it is voted. A proxy may be revoked by delivering a written notice of
revocation to the Secretary of the Company, by submitting prior to or at the
Annual Meeting a later dated proxy executed by the person executing the prior
proxy, or by attendance at the Annual Meeting and voting in person by the person
executing the proxy.

      This proxy statement, the accompanying proxy card and the Company's Annual
Report are being mailed to the Company's shareholders on or about August 8,
2003. The cost of soliciting proxies will be borne by the Company. The
solicitation will be made by mail and expenses will include reimbursement paid
to brokerage firms and others for their expenses in forwarding solicitation
material regarding the Annual Meeting to beneficial owners of the Company's
Common Stock. Further solicitation of proxies may be made by telephone or oral
communications with some shareholders. Such further solicitations would be made
by the Company's regular employees who will not receive additional compensation
for the solicitation.

                      OUTSTANDING SHARES AND VOTING RIGHTS

      Only holders of record of the 6,160,613 shares of the Company's Common
Stock outstanding at the close of business on July 28, 2003, are entitled to
notice of and to vote at the Annual Meeting or any adjournment thereof. A
majority of the shares, represented in person or by proxy, will constitute a
quorum for the transaction of business. All proxies delivered to the Company
will be counted in determining the presence of a quorum, including those
providing for abstention or withholding of authority and those delivered by
brokers voting without beneficial owner instruction and exercising a non-vote on
certain matters. The seven nominees for director receiving the highest number of
affirmative votes will be elected; votes withheld and votes against a nominee
have no practical effect. In matters other than election of directors, assuming
that a quorum is present, the affirmative votes of a majority of the shares
represented and voting at a meeting (which shares voting affirmatively also
constitute at least a majority


                                      -1-


of the required quorum) is required for approval; in such matters, abstentions
and broker non-votes are not counted. Each shareholder will be entitled to one
vote, in person or by proxy, for each share of Common Stock held of record on
the record date, except that all shareholders have cumulative voting rights and
in the event any shareholder gives notice at the Annual Meeting, prior to the
voting, of an intention to cumulate his or her votes in the election of
directors, then all shareholders entitled to vote at the Annual Meeting may
cumulate their votes in the election of directors. Cumulative voting means that
a shareholder has the right to give any one candidate whose name has been
properly placed in nomination prior to the voting a number of votes equal to the
number of directors to be elected multiplied by the number of shares such
shareholder would otherwise be entitled to vote, or to distribute such votes on
the same principle among as many nominees (up to the number of persons to be
elected) as the shareholder may wish. The proxy being solicited by the Board of
Directors confers discretionary authority to cumulate votes.

      The following table sets forth certain information with respect to the
beneficial ownership of the Company's Common Stock as of July 28, 2003 by (i)

                              ELECTION OF DIRECTORS

                                (Proposal No. 1)

      Directors are elected at each Annual Meeting of Shareholders and hold
office until their respective successors are duly elected and qualified. The
full Board of Directors consists of seven directors. Certain information with
respect to the seven nominees who will be presented at the Annual Meeting by the
Board of Directors for election as directors is set forth below. Although it is
anticipated that each nominee will be available to serve as a director, should
any nominee become unavailable to serve, the proxies will be voted for such
other person as may be designated by the Company's Board of Directors.

      Unless the authority to vote for directors has been withheld in the proxy,
the persons named in the enclosed proxy intend to vote at the Annual Meeting for
the election of the nominees presented below. However, discretionary authority
to cumulate votes represented by proxies and to cast such votes for any or all
of the nominees named below is solicited by the Board of Directors because, in
the event nominations are made in opposition to the nominees of the Board of
Directors, it is the intention of the persons named in the enclosed proxy to
cumulate votes represented by proxies in accordance with their best judgment for
individual nominees in order to assure the election of as many of the nominees
to the Board of Directors as possible.

      In the election of directors, assuming a quorum is present, the seven
nominees receiving the highest number of votes cast at the meeting will be
elected directors. As a result, proxies voted to "Withhold Authority" and broker
non-votes will have no practical effect upon the election of directors, although
proxies specifying "Withhold Authority" will be counted for purposes of
determining whether a quorum is present, as will proxies delivered by brokers
voting without beneficial owner instruction and exercising a non-vote on certain
matters.

      YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" ELECTION OF EACH OF
THE NOMINEES NAMED BELOW.

                                LEGAL PROCEEDINGS

      On April 22, 1997, a purported class action entitled JOHN P. CAVENY v.
QUALITY SYSTEMS, INC., ET AL. was filed in the Superior Court of the State of
California for the County of Orange, in which Mr. Caveny, on behalf of himself
and all others who purchased the Company's Common Stock between June 26, 1995
and July 3, 1996, alleges that the Company, and Sheldon Razin, Robert J. Beck,
Gregory S. Flynn, Abe C. LaLande, Donn Neufeld, Irma G. Carmona, John A. Bowers,
Graeme H. Frehner, and Gordon L. Setran (all of the foregoing individuals were
either officers, directors or both during the period from June 26, 1995 through
July 3, 1996), as well as other defendants not affiliated with the Company,
violated California Corporations Code Sections 25400 and 25500, California Civil
Code Sections 1709 and 1710, and California Business and Professions Code
Sections 17200 et. seq., by issuing positive statements about the Company that
allegedly were knowingly false, in part, in order to assist the Company and the
individual defendants in selling Common Stock at an inflated price in the
Company's March 5, 1996 public offering and at other points during the class
period. The complaint seeks compensatory and punitive damages in unspecified
amounts, disgorgement, declaratory and injunctive relief, and attorneys' fees.

      On May 14, 1997, a second purported class action entitled WENDY WOO v.
QUALITY SYSTEMS, INC., ET AL. was filed in the same court, essentially repeating
the allegations in the Caveny lawsuit and seeking identical relief. This action
was for all purposes consolidated with the Caveny action.


                                      -5-


      On July 1, 1997, a third purported class action entitled WADE CHENEY v.
QUALITY SYSTEMS, INC., ET AL. was filed in the United States District Court,
repeating essentially the same factual allegations as the April 22, 1997 suit
and purporting to state claims under the Federal securities laws. By court order
dated August 13, 1997, this action was stayed temporarily and the Court reserved
jurisdiction to lift the stay after all matters are final in the class action
filed on April 22, 1997. On August 15, 1997 the case was removed from the
Court's active caseload.

      On March 27, 2001, the court approved a notice of class certification to
be mailed to shareholders who are potential class members. Between April 9, 2001
and May 9, 2001, class notice was mailed to potential class members. Six class
members opted out of the class, and their requests were filed with the Court.

      On November 18, 2002, the parties reached an agreement to settle the
consolidated action. On January 6, 2003, the parties entered into a Stipulation
of Settlement whereby in consideration of a cash payment to the class fully
funded by the Company's directors and officers liability insurance, all members
of the class released all defendants from any and all claims that the class
members had or may have had relating to the purchase of the Company's securities
during the class period or based on any facts or events that were or could have
been asserted against the defendants in this action or in the companion Cheney
action referenced above. The settlement agreement expressly provides that the
Company and the named defendants do not admit, and continue to deny, any and all
allegations of wrongdoing.

      On January 14, 2003, the court granted preliminary approval of the
settlement, and approved a notice of the settlement that was mailed to
shareholders who were potential class members. Two additional class members
opted out of the settlement, and their requests were filed with the Court. On
April 14, 2003, the class action settlement was approved by the Court and an
Order and Final Judgment was entered dismissing the entire action with
prejudice.

      The releases given by the settling class in the Caveny action expressly
released all defendants from any and all claims that were or could have been
alleged in the Cheney action.

      The Company is a party to various other legal proceedings incidental to
its business, none of which are considered by the Company to be material.

                 BOARD OF DIRECTORS MEETINGS AND RELATED MATTERS

      The By-laws of the corporation require that at least three-quarters of the
members of the board of directors shall be independent. For purposes of any
action by the board, at least one-half of the directors present and eligible to
vote must be independent. An independent director means a person who::

      (a)   has never been an employee of the Company or any of its
            subsidiaries.

      (b)   provides no services to the Company or to the Chief Executive
            Officer or senior management of the Company as an advisor,
            consultant or otherwise.

      (c)   is not employed by an entity which provides services to the Company
            or to the Chief Executive Officer or senior management of the
            Company as an adviser, consultant or otherwise.

      (d)   is not affiliated with a significant customer or supplier of the
            Company ("significant" means more than 1% of annual sales).

      (e)   has not had, during the past two years, any interest in any
            significant transaction, or any business or financial relationship,
            with the Company or an affiliate of the Company (other than service
            as a director) for which the Company has been required to make
            disclosure under Regulation S-K of the Securities and Exchange
            Commission.

      (f)   is not a relative of an executive officer or director of the
            Company.

      (g)   receives no compensation from the Company other than director's
            fees.

      (h)   does not personally receive and is not an employee, director, or
            trustee of a foundation, university, or other institution that
            receives grants or endowments from the Company that


                                      -6-


            are material to the Company or to either the recipient and/or the
            foundation, university or institution.

      (i)   is not employed by an entity of which (i) an executive officer of
            the Company serves as a director or trustee, or (ii) a director of
            the Company serves in a senior executive capacity.

      During the fiscal year ended March 31, 2003, the Board of Directors held
ten meetings and there were two actions by unanimous written consent. No
director attended less than 75% of the aggregate of all meetings of the Board of
Directors and all meetings of committees of the Board of Directors upon which he
served except that Mr. Zikry attended six of the twelve Audit Committee meetings
and two of four Compensation Committee meetings. On May 30, 2003, Emad Zikry
resigned from the Board effective on that date. Mr. Zikry subsequently notified
the nominating committee of his interest in being nominated to the Board for the
next fiscal year. The nominating committee and the Board approved of his
nomination for election to the Board. If elected to the Board, it is anticipated
that Mr. Zikry shall receive 3,500 options to purchase the Company's common
stock under the Company's 1998 Stock Option Plan. These options shall vest
immediately upon grant and shall have an exercise price of $7.00 per share.

            During the fiscal year ended March 31, 2003, each member of the
Company's Board of Directors received correspondence from Mr. Hussein and his
counsel concerning issues related to the position of Lead Director and the
Company's four standing Board committees. In particular, Mr. Hussein has
objected to: (i) the election of Mr. Hanson, an independent director, as Lead
Director succeeding Mr. Hussein, (ii) the size and composition of the Board's
four standing committees and (iii) committee governance and functionality
issues. Mr. Hussein's objections generally originate from actions taken at the
Company's organizational meeting on August 29, 2002, wherein the Company's
independent directors elected a new Lead Director to replace Mr. Hussein and the
composition of the standing Board committees was altered. From September 1999
until August 29, 2002, Mr. Hussein served as Chairman of each of the Board's
committees and as Lead Director.

      A majority of the Company's Board members disagree with Mr. Hussein's
assertions. The Lead Director position has been filled by a duly elected
independent director and the Board's standing committees are each composed
entirely of independent directors in accordance with the Company's Corporate
Governance provisions. In addition, applicable Board committee matters and
recommendations are referred to the Company's Board of Directors for final
action as appropriate in concert with applicable laws and bylaws.

      The Board of Directors has an Audit Committee which consists of Messrs.
Hanson, Meyer and Mr. Small. During the past fiscal year and until May 30, 2003,
the Audit Committee consisted of Messrs. Hanson, Meyer and Zikry. Mr. Small was
appointed to the Audit Committee to fill the vacancy created upon the
resignation of Mr. Zikry on May 30, 2003 The Audit Committee is comprised
entirely of non-employee, independent directors and operates under a written
charter adopted by the Board of Directors. The duties of the Audit Committee
include meeting with the independent public accountants of the Company to review
the scope of the annual audit and to review the quarterly and annual financial
statements of the Company before the statements are released to the Company's
shareholders. The Audit Committee also evaluates the independent public
accountants' performance and makes recommendations to the Board of Directors as
to whether the independent public accounting firm should be retained by the
Company for the ensuing fiscal year. In addition, the Audit Committee reviews
the Company's internal accounting and financial controls and reporting systems
practices. During the fiscal year ended March 31, 2003, the Audit Committee held
twelve meetings. Mr. Zikry failed to attend the last six audit committee
meetings held during the fiscal year. During this period, the Audit Committee
continued to treat Mr. Zikry as though he were one of its members and received
no contrary indication from him concerning his


                                      -7-


membership. Mr. Small subsequently filled the vacancy caused when Mr. Zikry
resigned from the Board of Directors.

      The Board of Directors has a Nominating Committee which consists of
Messrs. Meyer and Small. The Nominating Committee is responsible for
identifying, recommending and nominating candidates to the Board of Directors
and is composed entirely of independent directors. The Nominating Committee will
consider candidate nominees for election as director who are recommended by
shareholders. Recommendations should be sent to the Secretary of the Company and
should include the candidate's name and qualifications and a statement from the
candidate that he or she consents to being named in the Proxy Statement and will
serve as a director if elected. In order for any candidate to be considered by
the Nominating Committee and, if nominated, to be included in the Proxy
Statement, such recommendation must be received by the Secretary on or before
the March 31st preceding the annual meeting at which directors will be elected
by the shareholders. During the fiscal year ended March 31, 2003 the Nominating
Committee held one meeting.

      The Board of Directors has a Compensation Committee which consists of
Messrs. Hanson, and Small. During the past fiscal year and until May 30, 2003,
the Compensation Committee consisted of Messrs. Hanson, Small and Zikry. The
Compensation Committee is composed entirely of independent directors, and is
responsible for (i) ensuring that senior management will be accountable to the
Board through the effective application of compensation policies and (ii)
monitoring the effectiveness of both senior management and the Board (including
committees thereof). The Compensation Committee establishes compensation
policies applicable to the Company's executive officers. During the fiscal year
ended March 31, 2003, the Compensation Committee held four meetings.

      The Board of Directors has a Transaction Committee which consists of
Messrs. Hanson, and Small. The Transaction Committee is responsible for
considering and making recommendations to the Company's Board of Directors with
respect to all proposals involving (i) a change in control of the Company or
(ii) the purchase or sale of assets constituting more than 10% of the Company's
total assets. The Transaction Committee has two members, all of whom are current
members of the Company's Board of Directors and all of whom must be independent
directors. During the fiscal year ended March 31, 2003, the Transaction
Committee held two meetings.

      If at any time the Chairman of the Board shall be an executive officer of
the Company, or for any other reason shall not be an independent director, a
non-executive Lead Director ("Lead Director") shall be selected by the
independent directors. The Lead Director shall be one of the independent
directors, shall be a member of the Audit Committee and of the Executive
Committee, if there is such a committee, and shall be responsible for
coordinating the activities of the independent directors. He shall assist the
Board in assuring compliance with the Company's corporate governance procedures
and policies, and shall coordinate, develop the agenda for, and moderate
executive sessions of the Board's independent directors. Such executive sessions
shall be held immediately following each regular meeting of the Board, and may
be held at other times as designated by the Lead Director. The Lead Director
shall approve, in consultation with the other Independent Directors, the
retention of consultants who report directly to the Board. If at any time the
Chairman of the Board is one of the independent directors, then he or she shall
perform the duties of the Lead Director. Between April 1, 2002 and August 28,
2002 Ahmed Hussein served as Lead Director. From August 29, 2002 through March
31, 2003 Dale Hanson served as Lead Director.

      The independent directors have organized an Executive Committee, which
consists of all of the independent directors, Messrs. El-Bardai, Hanson,
Hussein, Meyer, and Small. During the fiscal year ended March 31, 2003, the
Executive Committee held four meetings. The Executive Committee handles certain
matters as may be directed by the Board of Directors from time to time.

             Employment Contracts and Change in Control Arrangements

      Mr. Silverman has an Employment Agreement ("Agreement") with the Company
which details the terms of his employment as the Company's Chief Executive
Officer. The Agreement granted Mr. Silverman a total of 124,260 options which
vest equally over a four year period commencing with the effective date of the
Agreement (July 20, 2000). Additionally, on July 20, 2001 he received an
additional 59,940 options per his agreement. Mr. Silverman is eligible for a
cash bonus of up to 50% of his annual base compensation based on performance
goals established jointly between himself and the Board of Directors.

      Mr. Silverman's employment may be terminated for any reason by himself or
the Company upon 60 days written notice. Should Mr. Silverman terminate his
employment due to the Company's breach of the Agreement he will be entitled to
(i) a lump sum payment equal to six months base compensation; and (ii) immediate
vesting of 25% of all unvested stock options. Should Mr. Silverman's employment
be terminated without cause or by himself for good reason, he will be entitled
to (i) unpaid base


                                      -10-


compensation and vacation earned and accrued through his date of termination
plus a lump sum equal to six months base compensation, (ii) any other
performance bonus earned and not paid, and (iii) immediate vesting of an
additional 25% of all granted but unvested stock options. Should Mr. Silverman's
employment be terminated due to a "change of control" he will be entitled to (i)
unpaid base compensation and vacation earned plus a lump sum payment equal to
six months base compensation; (ii) any performance bonus earned but not paid;
and (iii) immediate vesting of all unvested options. A "change of control" is
defined as the earliest occurrence of any of the following events: the direct or
indirect sale, lease, exchange or other transfer of 35% of more of the total
assets of the Company, the merger or consolidation of the Company with another
company with the effect that the shareholders of the Company immediately prior
to the merger hold less than 51% of the combined voting power of the then
outstanding securities of the surviving company; the replacement of a majority
of the Company's Directors without the approval of the Board of Directors; the
purchase of 25% or more of the combined voting power of the outstanding
securities of the Company with the exception of the purchase of securities by
Ahmed Hussein or Sheldon Razin of shares owned by either Sheldon Razin or Ahmed
Hussein. The Agreement also grants immediate vesting of all unvested options
should a change of control occur whether or not Mr. Silverman's employment is
terminated.

      For options other than those discussed above, the Board of Directors, as
the administrator of the Company's 1989 Stock Option Plan and 1998 Stock Option
Plan, has the discretion to accelerate any outstanding options held by the Named
Executive Officers and employees in the event of an acquisition of the Company
by a merger or asset sale in which the outstanding options under each such plan
are not to be assumed by the successor corporation or substituted with options
to purchase shares of such corporation.

           REPORT OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION

      The Company applies a consistent philosophy to compensation for all
employees, including senior management. This philosophy is based on the premise
that the achievements of the Company result from the coordinated efforts of all
individuals working toward common objectives. The Company strives to achieve
those objectives through teamwork that is focused on meeting the expectations of
customers and shareholders.

                             Compensation Philosophy

      The goals of the compensation program are to align compensation with
business objectives and performance, and to enable the Company to attract,
retain and reward executive officers who contribute to the long-term success of
the Company. The Company's compensation program for executive officers is based
on the same four principles applicable to compensation decisions for all
employees of the Company:

      o     The Company pays competitively. The Company is committed to
            providing a pay program that helps attract and retain highly
            qualified people in the industry.

      o     The Company pays for relative sustained performance. Executive
            officers are rewarded based upon corporate performance, business
            unit performance and individual performance. Corporate performance
            and business unit performance are evaluated by the Board of
            Directors (in the case of the Chief Executive Officer) and by the
            Chief Executive Officer (in the case of all other executive
            officers) by reviewing the extent to which strategic and business
            plan goals are met, including such factors as operating profit,
            performance relative to competitors and timely new product
            introductions. Individual performance is evaluated by quantitatively
            and qualitatively reviewing organizational and management
            development

            progress against set objectives and the degree to which teamwork and
            Company values are fostered.

      o     The Company believes that employees should understand the
            performance evaluation and pay administration process. The process
            of assessing performance is as follows:

            1.    At the beginning of the performance cycle, the Chief Executive
                  Officer or other evaluating manager sets objectives and key
                  goals.

            2.    The evaluating manager gives the employee ongoing feedback on
                  performance.

            3.    At the end of the performance cycle, the manager objectively
                  and subjectively evaluates the accomplishment of
                  objectives/key goals.

            4.    The evaluating manager communicates evaluation results to the
                  employee.

            5.    The evaluation affects decisions on salary and, if applicable,
                  bonus and, if applicable, stock options.

                              Compensation Vehicles

      The Company has historically used a compensation program that consists of
multiple elements these elements include some or all of the following:

      o     Salary. The Company sets base salary for its employees at levels
            required to attract, retain, and motivate highly talented
            individuals at all levels in the organization.

      o     Bonus. The Company utilizes incentive compensation plans for
            selected employees to reward achievement of key objectives and
            goals.

      o     Stock Options. If/when utilized, stock options can be utilized to
            provide additional incentives to selected employees to work to
            maximize shareholder value. Any stock option grants are made by the
            Board of Directors. If granted, stock options generally are granted
            with an exercise price equal to the fair market value of the
            underlying Common Stock on the date of grant and vest in equal
            annual installments over a four-year period.

                             AUDIT COMMITTEE REPORT

      The Audit Committee reports to and acts on behalf of the Board of
Directors in providing oversight to the financial management, independent
auditors, and financial reporting procedures of the Company. The Company's
management is responsible for preparing the Company's financial statements and
the independent auditors are responsible for auditing those statements. In this
context, the Audit Committee has reviewed and discussed the audited financial
statements contained in the 2003 Annual Report on Form 10-K with management and
the independent auditors.


                                      -12-


      The Audit Committee has discussed with the independent auditors the
matters required to be discussed by the Statement on Auditing Standards No. 61
("Communication with Audit Committees"), as amended. The Audit Committee has
received the written disclosures and the letter from the independent auditors
required by Independence Standards Board Standard No. 1 (Independence
Discussions with Audit Committees), as amended, and has discussed with the
independent auditors their independence. In concluding that the auditors are
independent, the Committee considered, among other factors, whether the
non-audit services provided by Grant Thornton, LLP were compatible with
maintaining their independence.

      In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board of Directors that the audited financial
statements be included in the Company's Annual Report on Form 10-K for the year
ended March 31, 2003, for filing with the Securities and Exchange Commission.

      The Audit Committee has recommended the appointment of Grant Thornton, LLP
to serve as the Company's independent auditors for the year ended March 31,
2004, subject to shareholder ratification.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Under Section 16(a) of the Securities Exchange Act of 1934, as amended,
the directors and officers of the Company and any person who owns more than ten
percent of the Company's Common Stock are required to report their initial
ownership of the Company's Common Stock and any subsequent changes in that
ownership to the Securities and Exchange Commission ("SEC") and the NASDAQ
National Market. Officers, directors and greater than 10% shareholders are
required by SEC regulations to furnish the Company with copies of all forms they
file in accordance with Section 16(a).

      Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during the fiscal year
ended March 31, 2003, its officers, directors and greater than 10% shareholders
complied with all filing requirements applicable to such persons.

                 RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS

                                (Proposal No. 2)

      The Board of Directors has appointed the firm of Grant Thornton, LLP
("Grant Thornton") as its independent public accountants for the fiscal year
ended March 31, 2004, subject to ratification by the holders of a majority of
the shares represented either in person or proxy at the Annual Meeting. In the
event that the shareholders do not ratify the selection of Grant Thornton as the
Company's independent public accountants, the selection of another independent
public accounting firm will be considered by the Board of Directors.

      Representatives of Grant Thornton are expected to attend the Annual
Meeting and will be available to respond to appropriate questions. The
representatives of Grant Thornton also will have the opportunity to make a
formal statement, if they so desire.

      On July 5, 2001, the Company dismissed Deloitte & Touche as its
independent accountant. The report of Deloitte & Touche on the Company's
financial statements for the fiscal year ended March 31, 2001 contained no
adverse opinion or disclaimer of opinion and were not qualified or modified as
to uncertainty, audit scope or accounting principles.

      The Audit Committee's decision to change accountants was approved by the
Company's Board of Directors. In connection with its audits for the fiscal year
ended March 31, 2001, and through July 5, 2001, there were no disagreements with
Deloitte & Touche on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreements if not
resolved to the satisfaction of Deloitte & Touche would have caused them to make
reference thereto in their report on the financial statements for such years.
During the fiscal year ended March 31, 2001, and through July 5, 2001, there
were no reportable events (as defined in Regulation S-K Item 304(a)(1)(v)).
Deloitte & Touche furnished the Company with a letter addressed to the SEC
stating it agrees with the above statements. The Board of Directors approved the
engagement of Grant Thornton as its new independent accountant for the fiscal
year ending March 31, 2002 to replace Deloitte & Touche. During the fiscal year
ended March 31, 2001, and through July 5, 2001, the Company had not consulted
with Grant Thornton regarding either (i) the application of accounting
principles to a specified transaction, either completed or proposed; or the type
of audit opinion that might be rendered on the Company's financial statements;
or (ii) any matter that was either the subject of a disagreement, as that term
is defined in Item 304(a)(1)(iv) of Regulation S-


                                      -14-


K and the related instructions to Item 304 of Regulation S-K, or a reportable
event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K. The
Company authorized Deloitte & Touche to respond fully to any inquiries from
Grant Thornton relating to its engagement as Company's independent accountant.
