Annual Meeting of Stockholders

April 16, 2003

PROXY STATEMENT

Information Concerning Solicitation and Voting

General

The enclosed proxy is solicited on behalf of Integral Systems, Inc. (the “Company”) for the annual meeting of stockholders of the Company (the “Annual Meeting”) to be held at 6:00 p.m. on Wednesday, April 16, 2003, at Patuxent Greens Country Club, located at 14415 Greensview Drive, Laurel, Maryland or any adjournment or adjournments thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting.

These proxy solicitation materials were mailed on or about March 7, 2003 to all stockholders entitled to vote at the meeting.

Record Date; Outstanding Shares

Only stockholders of record at the close of business on February 14, 2003 (the “Record Date”) are entitled to receive notice of and to vote at the Annual Meeting. The outstanding voting securities of the Company as of the Record Date consisted of 9,709,538 shares of common stock of the Company, par value $.01 per share (the “Common Stock”). For information regarding holders of more than 5% of the outstanding Common Stock, see “Security Ownership of Certain Beneficial Owners and Management.”

Revocability of Proxies

The enclosed proxy is revocable at any time before its use by delivering to the Company a written notice of revocation or a duly executed proxy bearing a later date. If a stockholder who has executed and returned a proxy is present at the Annual Meeting and wishes to vote in person, he, she or it may elect to do so and thereby suspend the power of the proxy holders to vote his, her or its proxy.

Voting and Solicitation

Every stockholder of record on the Record Date is entitled, for each share held, to one vote on each proposal or item that comes before the meeting. All shares represented at the Annual Meeting by a proxy will be voted in accordance with the choices specified on the proxy. If no direction is given, proxies will be voted in accordance with the recommendations of the Board of Directors set forth in this Proxy Statement. A Board of Directors consisting of five directors is to be elected at the Annual Meeting (Proposal 1). In the election of directors, a plurality of the votes cast at the Annual Meeting at which a quorum is present is sufficient to elect a director. Thus, each stockholder will be entitled to vote for five nominees and the five nominees with the greatest number of votes will be elected. The ratification of the appointment of Ernst & Young LLP as the Company’s independent auditors for the fiscal year ending September 30, 2003 (Proposal 2) requires the affirmative vote of a majority of the votes cast at the Annual Meeting at which a quorum is present. Under Maryland law, there are no appraisal or dissenter’s rights with respect to any matter to be voted on at the Annual Meeting that is described herein. Proposal 1 and Proposal 2 are proposed by the Company.

The cost of soliciting proxies will be borne by the Company. In addition, the Company may reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding

1

solicitation materials to such beneficial owners. Proxies may also be solicited by certain of the Company’s directors, officers and regular employees, without additional compensation, personally or by telephone, telecopy or electronic mail.

Quorum; Abstentions; and Broker Non-Votes

The presence, in person or by proxy, of the holders of a majority of the shares entitled to be voted generally at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. An abstaining vote and a broker “non-vote” (a broker non-vote occurs if a broker or other nominee does not have discretionary authority and has not received instructions with respect to a particular item) are counted as present and entitled to vote and are, therefore, included for purposes of determining whether a quorum of shares exists. For purposes of electing directors (Proposal 1) and the ratification of the appointment of Ernst & Young LLP as the Company’s independent auditors (Proposal 2), abstentions and broker non-votes will not be treated as a vote cast and will not affect the outcome of such votes.

Stockholder Proposals

The Amended and Restated By-laws of the Company (the “Bylaws”) provide that, to be properly brought before the annual meeting, business must be (1) specified in the notice of the annual meeting (or any supplement thereto) given by the Company pursuant to the Bylaws, (2) brought before the annual meeting by or under the direction of the board of directors (or the chairman of the board, the chief executive officer or the president), or (3) properly brought before the annual meeting by a stockholder. In addition to any other applicable requirements, for business to be properly brought before the annual meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the Company. The Bylaws provide that nominations of persons for election to the board of directors of the Company may be made at the annual meeting, by or under the direction of the board of directors, or by any nominating committee or person appointed by the board of directors, or by any stockholder of the Company entitled to vote for the election of directors at the annual meeting who complies with the notice procedures set forth below. Such nominations, other than those made by or under the direction of the board of directors or by any nominating committee or person appointed by the board of directors, can only be made pursuant to timely notice in writing to the Secretary of the Company.

In each case, to be timely, such stockholder’s notice must be delivered to or mailed to and received by the Secretary of the Company at the principal executive offices of the Company, not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the date of the annual meeting (or, with respect to a proposal required to be included in the Company’s proxy statement pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, or its successor provision, the earlier date such proposal was timely received pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, or its successor provision). If, during the prior year the Company did not hold an annual meeting, or if the date of the annual meeting has changed more than 30 days from the first anniversary of the prior year’s annual meeting (other than as a result of adjournment), then, to be timely, such stockholder’s notice must be delivered to or mailed and received by the Secretary of the Company at the principal executive offices of the Company not earlier than the close of business on the 120th day prior to the date of the annual meeting and not later than the close of business on the later of the 90th day prior to the date of the annual meeting or the 10th day following the day on which public announcement (as described in the Company’s Bylaws) of the date of the annual meeting is first made.

Such stockholder’s notice shall set forth: (a) as to each person whom the stockholder proposes to nominate for election as a director, (1) the name, age, business address and residence address of the person, (2) the principal occupation or employment of the person, (3) the class and number of shares of the Company stock which are beneficially owned by the person, and (4) any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors pursuant to the rules and regulations under the Securities Exchange Act of 1934, as amended; (b) as to each matter the stockholder proposes to bring before the annual meeting, (1) a brief description of the business desired to be brought before the annual meeting, (2) the reasons for conducting such business at the annual meeting, and (3) any material interest of the stockholder in such business; and (c) as to the stockholder giving the notice, (1) the name and address of the stockholder and (2) the class and number of shares of the Company which are beneficially owned by the stockholder. The Company may require any proposed nominee or stockholder to furnish such other information as may reasonably

2

be required by the Company to determine the eligibility of such proposed nominee to serve as a director of the Company or the eligibility of the stockholder to bring business before the annual meeting.

Pursuant to applicable rules under the Securities Exchange Act of 1934, as amended, some stockholder proposals may be eligible for inclusion in the Company’s 2003 Proxy Statement and proxy card. Any such stockholder proposals must be submitted in writing to the Secretary of the Company no later than November 7, 2003. Stockholders interested in submitting such a proposal are advised to contact knowledgeable counsel with regard to the detailed requirements of such securities rules. Any such stockholder proposal should be addressed to the Company’s Secretary, Elaine M. Parfitt, and delivered to the Company’s principal executive offices at 5000 Philadelphia Way, Lanham, Maryland 20706-4417. It is suggested that proposals be forwarded by certified mail, return receipt requested.

If a stockholder intends to present a stockholder proposal at the 2003 annual meeting in a manner other than by the inclusion of the proposal in the Company’s proxy statement and proxy relating to that meeting, unless the stockholder has timely notified the Company of such intention pursuant to the notice requirements set forth above, the proxies named by the Company may exercise their discretionary voting authority on the matter in accordance with their best judgment.

Directors serve until the next annual meeting of stockholders and until successors have been duly elected and qualified. Officers are elected by the Board of Directors. Each officer holds office until his or her successor is elected or appointed and qualified or until his or her earlier resignation or removal.

Under the pension plan and the profit sharing plan, the Company contributes annually an aggregate amount equal to 5% of an eligible employee’s salary to the plans and may make additional contributions of up to 7% of an eligible employee’s salary. The employee may contribute up to an additional 25% as salary deferral. In each of fiscal years 2002 and 2001, the Company contributed a total of 11% of eligible employees’ salaries to both plans.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee is, and during the fiscal year ended September 30, 2002 was, comprised of Dominic A. Laiti, R. Doss McComas and Bonnie Wachtel, each a non-employee outside director. No member of the Compensation Committee was at any time during the year ended September 30, 2002 or at any time prior thereto an officer or employee of the Company or any of its subsidiaries.

Compensation Committee Report

The Compensation Committee, which is made up of three outside non-employee directors, determines the annual salary and bonuses awarded to the Chief Executive Officer and Chairman of the Board of Directors, Steven R. Chamberlain. The Compensation Committee may also make recommendations regarding compensation levels for other officers of the Company to Mr. Chamberlain, who determines the annual salaries and bonuses awarded to such officers on a discretionary basis.

The Compensation Committee’s policy on officer compensation is to offer or recommend (as the case may be) a package that includes a competitive salary, an annual bonus based on achieving certain Company goals and objectives and competitive benefits. The goal of the Compensation Committee in determining the compensation of Mr. Chamberlain and in making recommendations regarding compensation levels for other officers is to acquire and retain highly skilled executives, reward outstanding individual performance and align the compensation awarded to officers with the success of the Company. The Committee bases its salary determination or recommendations on the individual officer’s contributions to the Company and the responsibilities and duties that he or she performs. Bonuses are awarded or recommended by the Compensation Committee on the basis of achievement of certain Company and division revenue and earnings goals. Benefit packages offered to officers of the Company are similar to the benefits offered to all employees and include the Company’s health plan and 401(k) Pension and Profit Sharing Plan.

Annually, the Compensation Committee reviews and approves the compensation awarded to Mr. Chamberlain. Mr. Chamberlain has provided leadership and direction as the Company has continued to grow and expand. The Committee conferred a bonus of $40,000 for Mr. Chamberlain’s efforts during fiscal year 2002. Mr. Chamberlain’s salary for fiscal year 2002 was $255,544, which in light of his experience, contributions and responsibilities with the Company, the Committee finds reasonable and comparable to executives in similar size companies.

Stock Option Plan

Effective May 1, 2002, the Company established the 2002 Stock Option Plan (the “2002 Stock Option Plan”) to create additional incentives for the Company’s employees, consultants and directors to promote the financial success of the Company. Stockholders approved the 2002 Stock Option Plan at the annual meeting of the stockholders of the Company held on April 17, 2002. The maximum number of shares of Common Stock that may be issued pursuant to the 2002 Stock Option Plan is 750,000 shares. The Stock Option Committee has the authority to select full-time employees, directors or consultants to receive awards of options for the purchase of stock of the Company under this plan. Options to purchase a total of 176,250 shares of Common Stock were issued under the 2002 Stock Option Plan in fiscal year 2002. No shares of Common Stock were exercised during fiscal year 2002 under this plan. The Company has reserved for issuance an aggregate of 750,000 shares of Common Stock under the 2002 Stock Option Plan, of which options to purchase 179,250 shares are outstanding as of February 7, 2003. Pursuant to the 2002 Stock Option Plan, options may be incentive stock options within the meaning of Section 422 of the Code or nonstatutory stock options, although incentive stock options may be granted only to employees.

Effective May 25, 1988, the Company established a stock option plan, as amended and restated in 1994 and 1998 (the “1988 Stock Option Plan”), to create additional incentives for the Company’s employees, consultants and directors to promote the financial success of the Company. The Stock Option Committee had the authority to select full-time employees, directors or consultants to receive awards of options for the purchase of stock of the Company under this plan. The maximum number of shares of Common Stock issuable pursuant to the 1988 Stock Option Plan was increased from 300,000 to 1,200,000 during fiscal year 1994. At the annual meeting of stockholders of the Company held on July 22, 1998, the stockholders approved an amendment and restatement of the 1988 Stock Option Plan, which, among other changes, increased the number of shares subject to options under the 1988 Stock Option Plan from 1,200,000 to 1,800,000 shares. During the period of fiscal year 2002 prior to the adoption of the 2002 Stock Option Plan, options to purchase a total of 132,500 shares of Common Stock were issued under the 1988 Stock Option Plan. Pursuant to the approval of the 2002 Stock Option Plan by the stockholders of the Company at the annual meeting held on April 17, 2002, no further options will be granted under the 1988 Stock Option Plan. Options to purchase 262,470 shares of Common Stock granted under the 1988 Stock Option Plan were exercised during fiscal year 2002. The Company has reserved for issuance an aggregate of 751,180 shares of Common Stock under the 1988 Stock Option Plan, all of which are outstanding at February 7, 2003.

Termination of Employment and Change of Control Termination

The Company has no compensatory plan or arrangement with respect to any individual named in the Summary Compensation Table which results or will result from the resignation, retirement or any other termination of that individual’s employment with the Company or its subsidiaries or from a change in control of the Company or a change in the individual’s responsibilities following a change in control.

Certain Relationships and Related Transactions

On October 1, 2002, the Company acquired all of the issued and outstanding stock of Real Time Logic, Inc., a Colorado corporation (“RT Logic”), pursuant to an agreement and plan of reorganization for an initial purchase price payable to the shareholders of RT Logic of $13.25 million in cash and 683,870 shares of the Company’s Common Stock. Pursuant to the terms of the agreement and plan of reorganization, in November 2002, the former shareholders of RT Logic received additional aggregate consideration equal to $500,000 in cash and 25,806 shares of the Company’s Common Stock. The agreement and plan of reorganization provides that RT Logic shareholders will be entitled to receive contingent purchase price, which will be payable in the event that RT Logic’s business meets certain earnings performance targets during a period of up to four (4) years following the acquisition. Fifty percent (50%) of any contingent purchase price will be payable in cash and fifty percent (50%) thereof will be payable in shares of the Company’s Common Stock. Any Common Stock of the Company issued in connection with the contingent purchase price will be valued based on a 30-trading-day average leading up to the end of each applicable earn out period. The contingent purchase price is subject to claims by the Company under the indemnification provisions of the agreement and plan of reorganization. Patrick R. Woods, Executive Vice President, Government Programs, of the Company, served as an independent director of RT Logic from June 26, 2000 until the consummation of the acquisition of RT Logic by the Company and held approximately 0.3% of the outstanding shares of RT Logic common stock at the effective time of the acquisition.

The Company has entered into separate indemnity agreements with certain officers and employees and all directors of the Company which provide, among other things, that the Company will indemnify each such officer and director and advance expenses thereto, under the circumstances and to the extent provided for therein, to the fullest extent permitted by Maryland Law against judgments, penalties, fines, settlements and reasonable expenses actually incurred by such officer or director in the event he or she has been made, or is threatened to be made, a party to an action, suit or other proceeding, whether civil, criminal, administrative, investigative or otherwise, by reason of his or her present or prior service as a director, officer or employee of the Company, as the case may be, or present or prior service at the request of the Company as a director, officer or employee or as a fiduciary of an employee benefit plan, or as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

PROPOSAL TO RATIFY INDEPENDENT AUDITORS

(Proposal 2)

The Board of Directors, upon the recommendation of the current Audit Committee, has selected Ernst & Young LLP (“Ernst & Young”) as the independent auditors to audit the financial statements of the Company for the fiscal year ending September 30, 2003, and requests stockholder ratification of such selection. Ernst & Young were the independent auditors for the Company for the fiscal year ended September 30, 2002.

The independent public accountants for the Company for the fiscal year ended September 30, 2001 were Rubino & McGeehin, Chartered (“Rubino & McGeehin”). As reported in the Company’s Form 8-K filed on January 10, 2002 with the SEC, on January 4, 2002, the Company dismissed Rubino & McGeehin as the Company’s independent auditors and notified Rubino & McGeehin of their dismissal. On January 7, 2002, the Company engaged Ernst & Young as the Company’s independent auditors to audit the Company’s books and records for fiscal year 2002. Each of the dismissal of Rubino & McGeehin and the engagement of Ernst & Young was recommended and approved by the Audit Committee of the Company and was approved by the Board of Directors of the Company on January 4, 2002.

As reported in the Company’s Form 8-K filed on January 10, 2002 with the SEC, Rubino & McGeehin’s audit reports on the Company’s consolidated financial statements for the fiscal years ended September 30, 2001 and 2000 did not contain any adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles.

As reported in the Company’s Form 8-K filed on January 10, 2002 with the SEC, during the Company’s fiscal years ended September 30, 2001 and 2000 and the subsequent interim period preceding the date of Rubino & McGeehin’s dismissal, there were no “disagreements,” as that term is defined in Item 304 of Regulation S-K and the related instructions, with Rubino & McGeehin on any matter of accounting principles or

14

practices, financial statement disclosure or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Rubino & McGeehin, would have caused Rubino & McGeehin to make reference to the subject matter of such disagreement(s) in connection with their report. During the Company’s fiscal years ended September 30, 2001 and 2000 and the subsequent interim period preceding the date of Rubino & McGeehin’s dismissal, there were no “reportable events,” as that term is defined in Item 304 of Regulation S-K and the related instructions.

As reported in the Company’s Form 8-K filed on January 10, 2002 with the SEC, on January 4, 2002, the Company engaged Ernst & Young as the Company’s independent auditors to audit the Company’s books and records for fiscal year 2002. During the Company’s fiscal years ended September 30, 2001 and 2000 and the subsequent interim period preceding the engagement of Ernst & Young, the Company did not consult with Ernst & Young regarding either (1) 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 consolidated financial statements; or (2) any matter that was either the subject of a “disagreement,” as that term is defined in Item 304 of Regulation S-K and the related instructions, or a “reportable event,” as that term is defined in Item 304 of Regulation S-K and the related instructions.

The Company has authorized Rubino & McGeehin to respond fully to any inquiries of Ernst & Young.

A representative of Ernst & Young is expected to be present at the Annual Meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from stockholders of the Company. A representative of Rubino & McGeehin is not expected to be present at the Annual Meeting.

Audit Fees.    The aggregate fees billed by Ernst & Young for professional services rendered for the audit of the Company’s annual financial statements for fiscal year 2002 and the reviews of the financial statements included in the Company’s Forms 10-Q for fiscal year 2002 was $87,280.

Financial Information Systems Design and Implementation Fees.    The aggregate fees billed by Ernst & Young for professional services during fiscal year 2002 relating to the Company’s financial information systems were $0.

All Other Fees.    The aggregate fees billed by Ernst & Young for professional services rendered during fiscal year 2002 relating to the review of the Company’s tax returns, audit of the Company’s pension plans, consultations on accounting standards and other miscellaneous services was $30,050.

The Audit Committee has considered whether provision of the services described above under the caption “All Other Fees” was compatible with maintaining the independent auditors’ independence and has determined that such services did not adversely affect Ernst & Young’s independence.

Ernst & Young has advised the Company that neither Ernst & Young nor any of its members has any financial interest in the Company or any relation to the Company other than their duties as auditors and accountants.

The Proposal to Ratify the Selection of Ernst & Young as the Company’s Independent
