                        ------------------------------


                 INFORMATION CONCERNING SOLICITATION AND VOTING
                                        
GENERAL

     THE ENCLOSED PROXY IS SOLICITED ON BEHALF OF INTEGRAL SYSTEMS, INC. (THE
"COMPANY" OR "ISI") for the annual meeting of stockholders (the "Annual
Meeting") to be held at 6:00 p.m. on Wednesday, July 22, 1998, 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 July 1, 1998 to
all stockholders entitled to vote at the meeting.

RECORD DATE; OUTSTANDING SHARES

     Only stockholders of record at the close of business on June 9, 1998 (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 5,813,376 shares of Common Stock, $0.01 par value (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 person who has executed and returned a proxy is present at the
Annual Meeting and wishes to vote in person, he or she may elect to do so and
thereby suspend the power of the proxy holders to vote his or her 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.  In the election of directors, a plurality of the
votes cast at the Annual 

                                       1

 
Meeting at which a quorum is present is sufficient to elect a director. Thus,
each stockholder will be entitled to vote for six nominees and the six nominees
with the greatest number of votes will be elected. The ratification of the
independent auditors for the Company for the current year (Proposal 2) and
approval of the amendment to the 1988 Stock Option Plan (Proposal 4) will
require the affirmative vote of a majority of the votes cast by the stockholders
present in person or by proxy and entitled to vote at the Annual Meeting. The
proposed amendments to the Company's Articles of Incorporation (Proposal 3) must
be approved by the affirmative vote of two-thirds of all votes entitled to be
cast on the matter.

     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 solicitation
material 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; 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), ratification of the selection of
the Company's independent auditors (Proposal 2) and approval of the amendment to
the 1988 Stock Option Plan (Proposal 4), abstentions and broker non-votes will
not be treated as a vote cast and will not effect the outcome of such votes.
For purposes of approving the amendments to the Articles of Incorporation
(Proposal 3), abstentions and broker non-votes will have the same effect as a
negative vote.

DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS

     Proposals of stockholders of the Company which are intended to be presented
by such stockholders at the Company's 1999 annual meeting of stockholders must
be received by the Company no later than March 2, 1999 in order that they may be
included in the proxy statement and form of proxy relating to that meeting.  Any
such proposal should be addressed to the Company's Secretary and delivered to
the Company's principal executive offices at 5000 Philadelphia Way, Suite A,
Lanham, Maryland 20706-4417.

ANNUAL REPORT

     THE COMPANY'S ANNUAL REPORT TO STOCKHOLDERS, WHICH INCLUDES ITS ANNUAL
REPORT ON FORM 10-KSB FOR THE FISCAL YEAR ENDED SEPTEMBER 30, 1997, WAS
PREVIOUSLY PROVIDED TO STOCKHOLDERS.  A COPY OF THE COMPANY'S ANNUAL REPORT IS
ALSO AVAILABLE UPON WRITTEN REQUEST TO THE COMPANY AT 5000 PHILADELPHIA WAY,
SUITE A, LANHAM, MARYLAND  20706-4417, ATTN: CORPORATE SECRETARY.

                             ELECTION OF DIRECTORS
                                  (PROPOSAL 1)
GENERAL

     A Board of Directors consisting of six directors is to be elected at the
Annual Meeting.  Unless otherwise instructed, the proxy holders will vote all of
the proxies received by them for the Company's six nominees.  The six directors
nominated for election at the Annual Meeting are: Steven R. Chamberlain, Thomas
L. Gough, Dominic A. Laiti, R. Doss McComas, Robert P. Sadler and Bonnie K.
Wachtel (collectively, the "Nominees").  In the event that any of the Nominees
shall become unavailable, the proxy holders will vote in their discretion for a
substitute nominee.  It is not expected that any Nominee will be unavailable.

     The Bylaws of the Company provide that the number of members of the Board
of Directors shall consist of between three and seven directors.  Each director
is elected for a one-year term at each annual meeting of the stockholders.
Officers are elected by the Board of Directors.  Each officer holds office until
his successor is elected or appointed and qualified or until his earlier
resignation or removal.

     Proposal 3(a) as contained in the Proxy Statement would amend the Articles
of Amendment and Restatement of the Company's Articles of Incorporation (the
"Articles of Incorporation") to provide for staggered three (3) year terms for
the members of the Board of Directors (the "Staggered Board Amendment").  If the
Staggered Board Amendment is approved by the stockholders, the Directors who are
elected shall fill the terms as designated below:

Class I Directors:    Dominic A. Laiti, Robert P. Sadler
Class II Directors:   Thomas L. Gough, R. Doss McComas
Class III Directors:  Steven R. Chamberlain, Bonnie K. Wachtel

     Class I Directors' initial terms would expire at the 1999 annual meeting of
stockholders; Class II Directors' initial terms would expire at the 2000 annual
meeting of stockholders; and Class III Directors' initial terms would expire at
the 2001 annual meeting of stockholders.  In the event that the Staggered Board
Amendment is not approved, the terms of each of the elected directors will
expire at the next annual meeting of stockholders or when their successors are
elected and qualified.

     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" EACH OF THE
NOMINEES.

     Set forth below is certain information regarding the directors (including
the Nominees) and executive officers.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's officers and directors, and persons who
own more than 10% of the Company's Common Stock, to file reports of ownership
and changes in ownership of the Company's Common Stock with the Securities and
Exchange Commission and Nasdaq.  Based solely on a review of the copies of such
reports and written representations from the reporting persons that no other
reports were required, the Company believes that during the fiscal years ended
September 30, 1997 and 1996 its executive officers, directors and greater than
ten percent stockholders filed on a timely basis all reports due under Section

EMPLOYMENT AGREEMENTS

     There are no employment agreements in effect with respect to any directors
or executive officers of the Company.

COMPENSATION PURSUANT TO PLANS
 
     The Compensation Committee determines the annual bonuses and salary awarded
to Steven R. Chamberlain.  The Compensation Committee also makes recommedations 
regarding compensation levels for other officers of the Company to Steven R.
Chamberlain, who determines the annual bonuses and salaries awarded to such
officers on a discretionary basis. Currently, no formal plan exists for
determining bonus amounts. Prior to the formation of the Compensation Committee,
the functions currently performed by such committee were performed by the Board
of Directors as a whole.

     Effective October 1, 1987, the Company established a 401(k) pension and
profit sharing plan under Section 401 of the Internal Revenue Code.  Under the
plans, the Company contributes annually an amount equal to 5% of an eligible
employee's salary, and may make additional contributions of up to 7.5% of an
eligible employee's salary.  The employee may contribute up to an additional 10%
as salary deferral.  In fiscal years 1997 and 1996, the Company contributed a
total of 11% of eligible employees' salaries to both plans.

STOCK OPTION PLAN

     Effective May 25, 1988, ISI established a stock option plan, as amended and
restated in 1994 (the "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 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.  The maximum number of
shares of Common Stock which may be issued pursuant to the Stock Option Plan was
increased from 300,000 to 1,200,000 during fiscal year 1994.  Options to
purchase a total of 39,024 shares of Common Stock were issued and options to
purchase 9,706 shares of Common Stock were exercised during fiscal year 1997.
Total shares subject to options granted as of March 31, 1998 were
975,150.  Pursuant to the 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.

                                       11

 
     The Board of Directors is seeking stockholder approval of, and recommends
that the stockholders approve, an amendment to the Stock Option Plan which
would, among other changes, increase the number of shares subject to options
under the Stock Option Plan from 1,200,000 to 1,800,000 shares.  See Proposal 4.

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 such 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.


        RATIFICATION OF THE APPOINTMENT OF RUBINO & MCGEEHIN, CHARTERED
                           AS INDEPENDENT ACCOUNTANTS
                                  (PROPOSAL 2)
                                        
     Management has selected Rubino & McGeehin, Chartered as the independent
accountants to audit the books, records and accounts of the Company for the
current fiscal year ending September 30, 1998.  Rubino & McGeehin, Chartered has
audited the Company's financial statements since 1984.

     A representative of Rubino & McGeehin, Chartered is expected to be present
at the Annual Meeting and will have the opportunity to make a statement, and
will be available to answer questions from stockholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" RATIFICATION OF THE APPOINTMENT
OF RUBINO & MCGEEHIN, CHARTERED AS THE COMPANY'S INDEPENDENT ACCOUNTANTS.


                     AMENDMENT OF ARTICLES OF INCORPORATION
                                  (PROPOSAL 3)
                                        
     Each subsection of Proposal 3, including the Staggered Board Amendment and
the Series Preferred Stock Amendment, should be voted on as separate and
distinct amendments to the Articles of Incorporation.  Stockholders may approve
one amendment while rejecting the other.  As a result, one or more of the
amendments contained in Proposal 3 may be approved or disapproved.  The Form of
Articles of Amendment and Restatement attached hereto as Exhibit A reflect the
                                                         ---------            
content of the Company's Articles of Incorporation if both subsections to
Proposal 3 are approved by the stockholders.  However, if the stockholders do
not approve any one or more of the proposed amendments, the Articles of
Amendment and Restatement will be restated to reflect only those amendments that
are approved by the stockholders and will be filed as such with the State
Department of Assessments and Taxation of Maryland.

                                       12

 
                           STAGGERED BOARD AMENDMENT
                                (PROPOSAL 3(A))
                                STAGGERED BOARD
                                        
     The Board of Directors has determined that it would be advisable to amend
Article FIFTH of the Company's Articles of Incorporation to provide for
staggered elections of the board of directors (the "Staggered Board Amendment"),
such that each director would be elected to a three-year term with roughly one-
third of the directors elected each year.

     The Board of Directors has approved, subject to stockholder approval at the
Annual Meeting, the Staggered Board Amendment.  The Company's directors are
presently elected annually to hold office until the next annual meeting of
stockholders and until their successors are elected and qualified.  If the
Staggered Board Amendment is approved by the stockholders, directors will be
elected for three-year terms, with approximately one-third of such overall
directors elected each year; except that in order to implement the Staggered
Board Amendment at the Annual Meeting, Class I Directors will be elected for a
one-year term, Class II Directors will be elected for a two-year term and Class
III Directors will be elected for a full three-year term.  Thereafter, Class I
Directors will be elected for a full three-year term commencing with the 1999
annual meeting of stockholders and Class II Directors will be elected for a full
three-year term commencing with the 2000 annual meeting of stockholders.
Maryland law provides that a director elected by the Board of Directors to fill
a vacancy serves until the next annual meeting of stockholders and until his
successor is elected and qualifies.  In the event that the stockholders do not
approve the Staggered Board Amendment, the directors elected at the Annual
Meeting will continue to serve until the next annual meeting.

     Because the directors will be directly affected by the proposed Staggered
Board Amendment, they may be deemed to have an interest in the outcome of such
proposal.

     POSSIBLE BENEFITS OF THE STAGGERED BOARD AMENDMENT.  The Board of Directors
believes that a staggered system of electing directors would provide important
benefits to the Company, including the following:

     The staggered Board system helps assure continuity and stability of the
Company's business strategies and policies.  Because at least two stockholder
meetings will generally be required to effect a change in control of the Board,
a majority of directors at any given time will have prior experience as
directors of the Company.  This is particularly important to a growth-oriented
organization, such as the Company.

     In the event of an unfriendly or unsolicited proposal to take-over or
restructure the Company, the staggered Board system would give the Company time
to negotiate with the sponsor, to consider alternative proposals and to assure
that stockholder value is maximized.

     POSSIBLE ANTI-TAKEOVER EFFECT OF THE STAGGERED BOARD AMENDMENT.  A
staggered Board of Directors may be deemed to have an anti-takeover effect
because it may create, under certain circumstances, an impediment which would
frustrate persons seeking to effect a takeover or otherwise gain control of the
Company.  A possible acquiror may not proceed with a tender offer because it
would be unable to obtain control of the Company's Board of Directors for a
period of at least two years.  Generally, approximately one-third of the sitting
Board of Directors would be up for election at any annual meeting of the
stockholders.

                                       13

 
REMOVAL OF DIRECTORS FOR CAUSE

     Maryland law provides generally that directors may be removed from office
with or without cause by the affirmative vote of a majority of all of the votes
entitled to be cast for the election of directors.  Because the ability of a
simple majority of the stockholders to remove any director from office without
cause could frustrate the purposes of the proposed Staggered Board Amendment,
approval of such amendment will cause the Articles of Incorporation to be
amended to provide that if the common stock is quoted on the Nasdaq National
Market or listed on a national stock exchange, a Director may be removed from
office prior to the expiration of his or her term only for cause and then only
by the affirmative vote of the holders of at least 67% of the aggregate combined
voting power of all classes of capital stock entitled to vote in the election of
directors, voting as one class, and only at a special meeting of stockholders
called for such purpose.  However, if the common stock of the Company is not
either quoted on the Nasdaq National Market or listed on a national stock
exchange, then any director, or the entire Board of Directors, may be removed
from office at any time by the stockholders of the Company, with or without
cause, by the affirmative vote of a majority of all the votes entitled to be
cast for the election of directors.  Removal for cause is defined, in the
proposed amendment to the Articles of Incorporation, as the willful and
continuous failure of a director to perform duties to the Company (other than
any such failure resulting from temporary incapacity due to physical or mental
illness) or gross misconduct materially and demonstrably injurious to the
Company.  This proposed amendment to the Articles of Incorporation generally
follows Maryland corporate law, which provides that if the directors have been
divided into classes, a director may not be removed without cause, unless the
charter of the corporation provides otherwise.

     Under certain circumstances, the effect of these changes may be to impede
the removal of a director or directors of the Company, thus precluding a person
or entity from immediately acquiring control of the  Company's Board through the
removal of existing directors and the election of his or its nominees to fill
the newly-created vacancies.  Despite these removal provisions, all incumbent
directors are subject to nomination  and re-election by the stockholders at the
end of their term.

67% STOCKHOLDER APPROVAL FOR FUTURE AMENDMENTS TO BYLAWS TO CHANGE NUMBER OF
DIRECTORS

     The Company's Bylaws (the "Bylaws") currently provide that amendment of
such Bylaws requires the affirmative vote of the stockholders holding a majority
of the voting stock at an annual or special meeting called for that purpose or
an action of the whole Board.  Because this provision of the Bylaws could
frustrate the purposes of the proposed Staggered Board Amendment, approval of
such amendment will cause the Articles of Incorporation to be amended to provide
that the number of directors may only be changed if such change is approved by
the affirmative vote of (i) the holders of at least 67% of all the shares of the
Company then entitled to vote on such change or (ii) a majority of the directors
in office at the time of the vote.

THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR" THE
APPROVAL OF THE STAGGERED BOARD AMENDMENT.

                                       14

 
                        SERIES PREFERRED STOCK AMENDMENT
                                (PROPOSAL 3(B))
                                        
     Under the existing Articles of Incorporation, no shares of Preferred Stock
are authorized, issued or outstanding.  The Series Preferred Stock Amendment
(the "Series Preferred Stock Amendment") authorizes one million (1,000,000)
shares of preferred stock, par value $0.01 (the "Preferred Stock"), with an
aggregate par value of $10,000.  If approved by the stockholders, the Series
Preferred Stock Amendment would authorize the Board of Directors to issue
Preferred Stock, from time to time, in one or more series, with such
designations, voting powers, preferences, and relative, participating, optional,
conversion or other special rights, and such qualifications, limitations and
restrictions, as the Board of Directors may determine.

     The Board of Directors believes the proposed authorization of Preferred
Stock is desirable to enhance the Company's flexibility in connection with
possible future actions, such as stock splits, stock dividends, financings,
corporate mergers, acquisitions of property or other corporate purposes.  Having
such authorized shares available for issuance in the future would allow shares
of Preferred Stock to be issued without the expense and delay of a special
stockholder's meeting.  The shares of Preferred Stock would be available for
issuance without further action by the stockholders.

     The authorized but unissued shares of Preferred Stock could be used to
impede a change in control of the Company.  Under certain circumstances, such
shares could be used to create voting impediments or to deter persons seeking to
effect a takeover or otherwise gain control of the Company.  Such shares could
be sold in public or private transactions to purchasers who might side with the
Board of Directors in opposing a takeover bid which the Board of Directors
determines not to be in the best interests of the Company and its stockholders.
In addition, the Board of Directors could authorize holders of a series of
Preferred Stock to vote, either separately as a class or with the holders of
Common Stock, on any merger, sale or exchange of assets by the Company or any
other extraordinary corporate transaction.

     The Series Preferred Stock Amendment could have the effect of discouraging
an attempt by another person or entity, through the acquisition of a substantial
number of shares of the Company's Common Stock, to acquire control of the
Company with a view to imposing a merger, sale of all or any part of the
Company's assets or a similar transaction, since the issuance of new shares
could be used to dilute the stock ownership of such person or entity.
Furthermore, certain companies have issued, without stockholder action,
preferred stock, or warrants or other rights to acquire preferred stock, to the
holders of their common stock having terms designed to protect against the
adverse consequences to stockholders of certain takeovers, including partial
takeovers, and front-end loaded, two-step takeovers and freeze-outs and control
stockholder acquisitions.  Such issuances could have a detrimental effect on the
rights of holders of common stock, including loss of voting control.  If the
Series Preferred Stock Amendment is adopted, the rights, preferences and
privileges of holders of Common Stock would be subject to, and could be
adversely affected by, the rights of the holders of shares of any series of
Preferred Stock which the Company might designate and issue in the future.
Also, the Board of Directors could issue the Preferred Stock with voting and/or
conversion rights and thereby dilute the voting power and equity of the holders
of Common Stock and adversely effect the market price of such stock.  The
Company has no present plans to issue shares of Preferred Stock.

THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR" THE
APPROVAL OF THE SERIES PREFERRED STOCK AMENDMENT.

                                       15

 
     The above summary descriptions of the proposed amendments to the Company's
Articles of Incorporation are not intended to be complete and are qualified in
their entirety by reference to the complete text of the proposed Articles of
Amendment and Restatement contained in Exhibit A hereto.
                                       ---------        


                  PROPOSAL TO AMEND THE 1988 STOCK OPTION PLAN
                                  (PROPOSAL 4)
                                        
Amendments
- ----------

     The Board of Directors proposes that the Stock Option Plan be amended and
restated to (i) increase the number of shares of Common Stock available for the
grant of options under the Stock Option Plan from 1,200,000 to 1,800,000, and
(ii) allow within the discretion of the governing Stock Option Plan Committee
(the "Committee") a "cashless" exercise of stock options issued after the
amendment and restatement by payment of the exercise price through withholding
of shares of a value equal to the exercise price that would otherwise be issued
upon option exercise.  The restated Stock Option Plan would also incorporate
recent amendments to: (i) allow arrangements with a broker to facilitate a
cashless exercise by raising the proceeds for option exercise via a sale or loan
with respect to the shares to be issued upon option exercise, (ii) eliminate
certain six-month holding periods for shares issued upon option exercise to
certain directors and officers consistent with changes to Rule 16b-3 of the
Exchange Act and (iii) make certain other changes of a technical nature.  A
description of the amendment and restatement of the Stock Option Plan is set
forth below and is qualified by reference to the full text of the proposed
amendment and restatement which is set forth as Exhibit B to this Proxy
                                                ---------              
Statement.

     The Stock Option Plan was initially adopted on May 25, 1988.  An amendment
and restatement of the Stock Option Plan was adopted by the Board of Directors
effective January 1, 1994 and approved by stockholders on July 21, 1994.  As of
March 31, 1998, of the 1,200,000 shares authorized for issuance under the Stock
Option Plan, 224,850 shares remained available for issuance.

     The Board of Directors believes that it is in the Company's interest that
stock options continue to comprise a meaningful part of compensation for
officers, directors, employees and consultants and that the authorization of
additional shares under the Stock Option Plan is therefore desirable.
Accordingly, the Board of Directors has voted, subject to stockholders approval,
to increase the number of shares of the Company's Common Stock available for
stock options under the Stock Option Plan by an additional 600,000 shares.
Further, allowing exercise of stock options by withholding of shares equal in
value to the exercise price will be particularly valuable to option holders who
may be otherwise precluded by securities laws from selling the shares received
on exercise to raise sufficient cash proceeds to cover the exercise price.
Finally, allowing cashless exercises through assistance of brokers and making
other changes consistent with revised Rule 16b-3 will increase the flexibility
of Stock Option Plan participants in realizing the value of their benefits
received under the Stock Option Plan.

Description
- -----------

     In General.  The Stock Option Plan is administered by a committee of three
members of the Company's Board of Directors who are non-employee, outside
directors (the "Committee").  The Stock Option Plan authorizes the Committee 
within its discretion to grant to any of the directors, officers, other 
employees and consultants of the Company and its subsidiaries stock options to
purchase shares of the Company's Common Stock.  Presently, three directors, 
ten officers, 134 employees and two 

                                       16

 
consultants are eligible to receive stock options under the Stock Option Plan.
The purpose of the Stock Option Plan is to benefit the Company by giving
directors, officers, employees and consultants of the Company and its
subsidiaries a greater personal interest in the success of the enterprise. Stock
options which qualify as Incentive Stock Options under Section 422(b) of the
Internal Revenue Code of 1986, as amended (the "Code"), as well as Non-Qualified
Stock Options (as defined under the Code) which do not qualify for such
treatment, may be granted by the Committee under the Stock Option Plan.

     Exercise Price. The exercise price per share under an Incentive Stock
Option must be at least the fair market value of a share of the Company's Common
Stock on the date the stock option is granted.  Additionally, the exercise price
per share for any Incentive Stock Option granted to any individual who owns
stock representing more than 10% of the total combined voting power of all
classes of stock of the Company or any subsidiary, within the meaning of Section
424(f) of the Code, taking into account the attribution rules of Section 424(d)
of the Code, must be at least 110% of the fair market value of the Company's
Common Stock on the date such Incentive Stock Option is granted.  However, Non-
Qualified Stock Options may be granted at a price which is less than the then-
current market value of the Company's Common Stock.  The exercise price of each
option grant is determined by averaging the high and low price for the Company's
Common Stock for the month in which the employee commences employment with the
Company.

     Exercise of Options.  An option shall vest and thereby become exercisable
at such times and in such installments as the Committee shall provide in the
terms of each individual option grant agreement.  The expiration date of an
option is also determined by the Committee, although no option shall have a term
in excess of ten years and Incentive Stock Options granted to holders of more
than 10% of the voting stock of the Company may not have a term in excess of
five years.  Generally, unless the Committee determines otherwise, (i) unvested
options are forfeited upon the termination of employment or other affiliation
with the Company, (ii) vested Incentive Stock Options are forfeited three months
thereafter except in the event of termination due to disability or death in
which case such options are forfeited 12 months thereafter, and (iii) vested
Non-Qualified Stock Options are forfeited or exercisable upon termination as
provided in the respective grant agreement.

     Payment of Exercise Price.  Shares purchased upon exercise of an option
must be paid for in full at the time of exercise in cash or, if the Committee so
permits, in whole or in part in shares of the Company's Common Stock valued at
their fair market value at the date of exercise.  Under the amendment and
restatement of the Stock Option Plan, the Committee may permit a so-called
"cashless" exercise of stock options by payment of the exercise price through
withholding of shares of a value equal to the exercise price that would
otherwise be issued upon option exercise.  The Committee may also permit
arrangements with a broker to facilitate a cashless exercise by raising the
proceeds for option exercise via a sale or loan with respect to the shares to be
issued upon option exercise.

     Limitations Regarding Option Grants.  The aggregate number of shares of the
Company's Common Stock which may be made the subject of options under the
amendment and restatement of the Stock Option Plan shall not exceed 1,800,000
shares, of which options with respect to 975,150 shares have been granted as of
March 31, 1998.  Shares of stock subject to an option which has been forfeited
or canceled before exercise may again be available for awards under the Stock
Option Plan.  The maximum number of shares that may be granted in any fiscal
year to any person may not exceed 50,000.  The aggregate fair market value of
stock (determined at the time of grant) for which an optionee may exercise
Incentive Stock Options for the first time during any calendar year may not
exceed $100,000.  The Stock Option Plan provides that the Committee may make
equitable 

                                       17

 
adjustments in the terms of options and the maximum number of shares
available under the Stock Option Plan in the event of certain corporate events,
such as reorganizations, mergers or recapitalizations.  The Committee may also
issue options to employees of corporations acquired by the Company in
substitution of, and with provisions similar to, options held in the acquired
corporation.

     Amendment and Termination.  The Stock Option Plan may be amended by the
Board of Directors at any time, provided that, without the approval of the
holders of a majority of the Company's Common Stock, no amendment may be made
which (i) increases the maximum number of shares available under the Stock
Option Plan, (ii) changes the requirements for eligibility to receive stock
options under the Stock Option Plan, (iii) extends the period for granting
options or (iv) materially increases the benefits accruing to participants under
the Stock Option Plan.  No grants may be made under the Stock Option Plan after
May 8, 2008, at which date the Stock Option Plan will terminate absent action by
the Board of Directors and stockholders.

     Recent Price of Common Stock.  The closing price of the Company's Common
Stock on the Nasdaq SmallCap Market on June 26, 1998 was $15.00 per share.

Federal Income Tax Consequences
- -------------------------------

     The following discussion is a general summary of the material U.S. federal
income tax consequences to U.S. participants in the Stock Option Plan and is
intended for general information only.  The discussion is based on the Code,
regulations thereunder, and rulings and decisions now in effect, all of which
are subject to change.  This summary does not discuss all potential tax
consequences and individual circumstances may be such that exceptions to these
rules apply.  Also, tax consequences may be subject to change.  Therefore, Stock
Option Plan participants are advised to consult their own tax advisors with
respect to their individual tax treatment.

     Non-Qualified Stock Options ("NQSOs").  For federal income tax purposes,
the recipient of NQSOs granted under the Stock Option Plan will not have taxable
income upon the grant of the option, nor will the Company then be entitled to
any deduction.  Generally, upon exercise of NQSOs, the optionee will realize
ordinary income, in an amount equal to the excess, if any, of the fair market
value of the stock at the date of exercise over the exercise price.  The Company
will generally be entitled to a deduction in an amount equal to such difference
provided it properly reported the optionee's income on an informational return.
An optionee's basis for the stock for purposes of determining his gain or loss
on his subsequent disposition of the shares generally will be the fair market
value of the stock on the date of exercise of the NQSO.

     Notwithstanding the above, an optionee who is an "insider" within the
meaning of the Exchange Act and subject to a claim for "short-swing" profits
under Section 16(b) of the Exchange Act will not generally be subject to federal
income tax as the result of the exercise on an NQSO until such time as he or she
is no longer subject to such a claim.  Such an insider may, however, elect under
Code Section 83(b) to include in his or her taxable income at the time of
exercise the excess of the fair market value of the Common Stock received over
the exercise price.  Insiders should consult their own tax advisors on these
matters.

     Incentive Stock Options ("ISOs").  Generally there is no taxable income to
an optionee when an ISO is granted to him or when that option is exercised.
(However, the optionee's alternative minimum taxable income will generally
include an amount equal to the difference between the option exercise price and
the fair market value at the time of exercise.)  Gain realized by an optionee
upon 

                                       18

 
sale of stock issued on exercise of an ISO is taxable at capital gains
rates.  No tax deduction is available to the Company unless the optionee
disposes of the shares within two years after the date of grant of the option or
within one year of the date the shares were transferred to the optionee.  In
such event, the excess of the fair market value of the shares on the date of
exercise over the option exercise price will be taxed at ordinary income rates.
The Company will be entitled to a deduction to the extent the employee must
recognize ordinary income.  An ISO exercised more than three months after an
optionee's termination of employment, other than by reason of death or
disability, will be taxed as a NQSO, with the optionee deemed to have received
income upon such exercise taxable at ordinary income rates.  In that case, the
Company will be entitled to a tax deduction equal to the ordinary income, if
any, realized by the optionee.

     Exercise with Previously Owned Shares. As a general rule, the delivery of
Company Common Stock to exercise an option granted under the Stock Option Plan
is treated as a nontaxable exchange to the extent that the optionee receives an
equal number of shares of Company Common Stock upon exercise of the option.  The
tax basis of the shares received will be the same as the optionee's tax basis
for the tendered shares.  The excess of the value of any additional shares
received over any money paid upon exercise constitutes taxable income in the
case of a NQSO, but not in the case of an ISO.  Any additional shares received
upon the exercise of a NQSO will have an aggregate basis equal to the amount
included in the optionee's income as a result of the exercise of the option plus
any money paid (i.e., generally their fair market value).  Any additional shares
received upon the exercise of an ISO will have a tax basis equal to the amount
of the money paid, if any.

     There is one exception to the above rules.  If the Company Common Stock
used to effect the exchange was received pursuant to the exercise of an ISO and
the requisite holding period requirements have not been satisfied (including
circumstances where shares are withheld or otherwise tendered pursuant to a
cashless exercise of an ISO), the tender of such shares would constitute a
disqualifying disposition.  In that case, the exchange of such shares would be
treated as a taxable exchange, not a nontaxable exchange.  The optionee would
recognize income upon the exchange of such shares as described in the Section
above.

     Tax Withholding.  The Company, to the extent permitted or required by law,
will have the right to deduct from any payment owed to a participant (including
salary or other compensation), any such federal, state or local taxes required
to be withheld with respect to the exercise of an option or related delivery of
shares under the Stock Option Plan.  Under the Stock Option Plan, if authorized
by the Committee, a participant may deliver shares of the Company's Common
Stock, including shares acquired upon exercise of an option, to pay withholding
taxes due on exercise of the option.  The delivery of Common Stock of the
Company to pay withholding taxes generally will result in a taxable gain to the
participant to the extent that this value exceeds the participant's basis in the
stock.  If the Common Stock delivered was acquired pursuant to the exercise of
an ISO and the requisite holding period requirements have not been satisfied
(including circumstances where shares are withheld upon the exercise of an ISO
to pay the withholding taxes), a disqualifying disposition will result.

     Section 162(m).  Under Section 162(m) of the Code, income tax deductions of
publicly-traded companies may be limited to the extent total annual compensation
(including base salary, annual bonus, stock option exercises and non-qualified
benefits) paid to certain executive officers exceeds $1 million in any one year.
However, under Section 162(m), the deduction limit does not apply to certain
"qualified performance-based compensation" established by an independent
compensation committee which is adequately disclosed to, and approved by,
stockholders.  In particular, stock options will satisfy the performance-based
exception if the awards are made by a qualifying compensation committee under a
plan that has been approved by the company's 

                                       19

 
stockholders, if the plan states the maximum number of shares that can be
granted to any particular employee within a specified period and if the
compensation is based solely on an increase in the stock price after the grant
date (i.e., the option exercise price is equal to or greater than the fair 
market value of the stock subject to the award on the grant date).

Accounting Treatment
- --------------------

     Generally, the Company's reported earnings will not be affected by the
grant of options or the exercise of stock options, excepting the case where the
exercise price is less than the fair market value of the Common Stock at the
date of grant.  Stock option grants, however, may impact the calculation of
diluted earnings per share, by virtue of being deemed to have been exercised
under certain circumstances.

Options Granted
- ---------------

     The following table sets forth as of March 31, 1998, under the Stock Option
Plan, the number of options granted to (i) each Named Officer of the Company;
(ii) all current executive officers as a group; (iii) all current directors who
are not executive officers as a group; and (iv) all employees, including all
current officers who are not executive officers, as a group.  Grants under the
Plan will be made at the discretion of the Committee and, accordingly, future
grants are not yet determinable.

changed only by receiving the affirmative vote of (i) the holders of at least

after their election, provided that the stockholders electing new or replacement
directors may from time to time specify a term of less than three years in order
to maintain the number of directors in each class as nearly equal as possible.

shall continue in effect until all matters relating to the payment of the Awards
and the administration of the Plan have been settled.

4.1    ADMINISTRATION.  Except where this Plan expressly reserves administrative
or other powers to the Company or the Board, this Plan shall be administered by
the Committee.  All questions or interpretation and application of this Plan, or
of the terms and conditions pursuant to which Awards are granted, exercised or
forfeited under the provisions hereof, shall be subject to the determination of
the Committee.  Such determination shall be final and binding upon all parties
affected thereby.

                                       3

 
       It is contemplated that Awards granted hereunder will be recommended by
the management of the Company or the Board to the Committee, and that the
Committee will determine whether to accept such recommendations.

5.1    GRANTS OF AWARDS; NUMBER OF SHARES. The Committee may, from time to time,
grant Awards of Options to one or more Eligible Employees or Eligible Non-
Employees in its discretion; provided, however, that:

       (i)   subject to any adjustment pursuant to Article X or Article XI, the
aggregate number of shares of Stock subject to Awards under this Plan may not
exceed One Million Eight Hundred Thousand (1,800,000) shares of Stock;
 
       (ii)  to the extent that an Award lapses or the rights of the Participant
to whom it was granted terminate, or to the extent that the Award is canceled by
mutual agreement of the Committee and the Participant (which cancellation
opportunities may be offered by the Committee to Participants from time to
time), any shares of Stock subject to such Award shall again be available for
the grant of an Award hereunder;

       (iii) shares of Stock ceasing to be subject to an Award because of the
exercise of an Option shall no longer be available for the grant of an Award
hereunder; and

       (iv)  Eligible Non-Employees shall not be entitled to receive Awards of
Incentive Stock Options.

       In determining the size of Awards, the Committee may take into account
recommendations by the Board or the Company's management, a Participant's
responsibility level, performance, potential, and cash compensation level, the
Fair Market value of the Stock at the time of Awards and such other
considerations as it deems appropriate.

       The maximum number of shares of Stock subject to Options that may be
granted during any one calendar year to any one individual shall be limited to
50,000.  To the extent required by Code Section 162(m), and so long as Section
162(m) of the Code is applicable to persons eligible to participate in the Plan,
shares of Stock subject to the foregoing limit with respect to which the related
Option is terminated, surrendered or canceled shall not again be available for
grant to the respective grantee under this limit.

6.1    ELIGIBLE INDIVIDUALS.  All Eligible Employees and Eligible Non-Employees
shall be eligible to receive Awards hereunder.  Subject to the provisions of
this Plan, the Committee shall from time to time select from such Eligible
Employees and Eligible Non-Employees those to whom Awards shall be granted and
determined the size of the Awards.  A Participant may hold more than one Option
at any one time.  No person shall have any right to be granted an Award under
this Plan, as all Awards granted hereunder are granted in the sole and absolute
discretion of the Committee, as provided herein.

7.1    GRANTS OF OPTIONS. Awards shall be granted to Participants in the form of
Options to purchase Stock.

7.2    TYPE OF OPTIONS. The Committee may choose to grant a Participant who is
an Eligible Employee either Incentive Stock Options or Non-Qualified Stock
Options or both, subject to the limitations contained herein. The Committee
shall grant to a Participant who is an Eligible Non-Employee only Non-Qualified
Stock Options, subject to the limitations contained herein.

7.3    INCENTIVE STOCK OPTION DOLLAR LIMITATIONS.  If the Committee grants
Incentive Stock Options, the aggregate Fair Market Value (determined as of the
date the Option is granted) of any such Options plus any incentive stock options
granted under any other plans of the Company which shall be first exercisable by
any one Participant during any one calendar year shall not exceed $100,000, or
such other dollar limitation as may be provided in the Code.

                TERMS AND CONDITIONS OF STOCK OPTION AGREEMENTS
                -----------------------------------------------
                                        
8.1    STOCK OPTION AGREEMENTS.  Awards shall be evidenced by Stock Option
Agreements in such form as the Committee shall, from time to time, approve.
Such Stock Option Agreements, which need not be identical, shall comply with and
be subject to the following terms and conditions:

       (a)  Medium of Payment. Upon exercise of the Option, the Option price
shall be payable either (i) in United States dollars, in cash, or by certified
check, bank draft or money order payable to the order of the Company, or (ii) in
the discretion of the Committee, through the delivery of shares of Stock
(including, for Options granted after 

                                       5

 
the date of this amendment and restatement, Stock that would otherwise be issued
upon exercise of the Option), with the Fair Market Value equal to the total
Option price, or (iii) by a combination of the methods described in (i) and
(ii).

       In addition to the above, with respect to Options granted after the date
of this amendment and restatement, the Committee, subject to such limitations as
it may determine, may authorize payment of the exercise price, in whole or in
part, by delivery of a properly executed exercise notice, together with
irrevocable instructions to: (i) a brokerage firm designated by the Company to
deliver promptly to the Company the aggregate amount of sale or loan proceeds to
pay the exercise price and any withholding tax obligations that may arise in
connection with the exercise, and (ii) the Company to deliver the certificates
for such purchased shares directly to such brokerage firm.

       (b)  Number of Shares.  The Stock Option Agreement shall state the total
number of shares to which it pertains.

       (c)  Option Price. With respect to Non-Qualified Stock Options, the
option price shall be an amount determined by the Committee, which amount may be
less than, equal to or greater than the Fair Market Value of such Shares on the
date of the granting of the Option. With respect to Incentive Stock Options, the
option price shall be not less than the Fair Market Value of such shares on the
date of the granting of the Option (or one hundred ten percent (110%) of such
amount if the Option is granted to an individual owning stock possessing more
than ten percent (10%) of the total combined voting power of all classes of
stock of Integral Systems, Inc. or any subsidiary, within the meaning of Code
Section 424(f), taking into account the attribution rules of Code Section
424(d)).

       (d)  Term of Options. Each Non-Qualified Option and Incentive Stock
Option granted under this Plan shall expire not more than ten (10) years from
the date the Option is granted, except that each Incentive Stock Option granted
under the Plan to an individual owning stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of Integral
Systems, Inc. or any subsidiary, within the meaning of Code Section 424(f),
taking into account the attribution rules of Code Section 424(d), shall expire
not more than five (5) years from the date the Option is granted.

       (e)  Date of Exercise. Subject to subsection (d) of this Section, an
Option which becomes a Vested Option may be exercised in whole or in part at any
time thereafter. Options which are awarded hereunder shall become exercisable as
Vested Options, as follows:

            (i)   The aggregate number of shares of Stock subject to any Award
shall be divided into three installments (equally or unequally at the discretion
of the Committee), as specified in the Agreement. The first installment shall
become Vested Options one year from the date of such Award, the second
installment shall become Vested Options two years from the date of such Award
and the third installment shall become Vested Options 

                                       6

 
three years from the date of such Award. Any other vesting schedule may be
substituted for the above, as specified in the Agreement, at the Committee's
discretion.

            (ii)  Except as otherwise provided hereunder, the Committee may in
its discretion accelerate the time at which an Option granted hereunder may be
exercised.

       (f)  Forfeiture or Exercise of Option. If a Participant ceases employment
with the Company, all Options held by him or her which are not Vested Options
shall terminate. If a Participant terminates his or her employment or other
service relationship with the Company prior to the exercise of the Participant's
Non-Qualified Stock Options, such Options shall be forfeited (or exercisable
after termination only as provided in the applicable Stock Option Agreement). If
a Participant terminates employment with the Company prior to exercise of the
Participant's Vested Options which are Incentive Stock Options, such Vested
Options shall be forfeited, or be exercised, as follows:

            (i)   Termination and Retirement.  In the event of a Participant's
Termination or Retirement, the Participant's Vested Options shall be forfeited
within three (3) months of the Participant's Termination or Retirement.

            (ii)  Disability. Upon the Disability of a Participant, the
Participant's Vested Options shall be exercisable within twelve (12) months (or
such shorter period as the Code or the terms of the particular Stock Option
Agreement may require) of the Participant's Date of Disability.

            (iii) Death.  If the Participant dies while in the employment of the
Company or within the period of time after Termination or Retirement during
which the Participant would have been entitled to exercise his or her Vested
Option rights, the Participant's estate, personal representative or beneficiary
(as applicable) shall have the right to exercise such Vested Options, within one
(1) year from the date of the Participant's death (or such shorter period as the
Code or the terms of the particular Stock Option Agreement may require).

            (iv)  Other Restrictions/Forfeiture Events. The Committee shall have
complete discretion to prescribe any other events of forfeiture and/or
conditions of exercisability of Options, as specified in the applicable
Agreement.

       (g)  Agreement as to Sale of Securities. If, at the time of the exercise
of any Option, in the opinion of counsel for the Company, it is necessary or
desirable, in order to comply with any applicable laws or regulations relating
to the sale of securities, that the Participant exercising the Option shall
agree to purchase the shares that are subject to the Option for investment only
and not with any present intention to resell the same and that the Participant
will dispose of such shares only in compliance with such laws and regulations,
the Participant will, upon the request of the Company, execute and deliver to
the Company an agreement to such effect.

                                       7

 
       (h)  Required Amendments.  Each Award shall be subject to any provision
necessary to assure compliance with federal and state securities laws.

       (i)  Limitation of Participant Rights. A Participant shall not be deemed
to be the holder of, or to have any of the rights of a holder with respect to,
any shares of Stock subject to an Option unless and until the Option shall have
been exercised pursuant to the terms thereof, the Company shall have issued and
delivered the shares to the Participant, and the Participant's name shall have
been entered as a stockholder of record on the books of Integral Systems, Inc.
Thereafter, the Participant shall have full voting, dividend and other ownership
rights with respect to such shares of stock.

9.1    SUBSTITUTE AWARDS.   Awards may be granted under this Plan from time to
time in substitution for similar awards held by employees of corporations who
become or are about to become employees of the Company as the result of a merger
or consolidation of the employing corporation with the Company, or the
acquisition by the Company of the assets of the employing corporation, or the
acquisition by the Company of fifty percent (50%) or more of the stock of the
employing corporation causing it to become a subsidiary of the Company.  Subject
to the procurement of the approval of the stockholders of the Company as may be
required for the Plan to satisfy the requirements of Rule 16b-3 under the
Securities Exchange Act of 1934, as amended, the terms and conditions of the
substitute Awards so granted may vary from the terms and conditions set forth in
this Plan to such extent as the Committee at the time of the grant may deem
appropriate to confirm, in whole or in part, to the provisions of the options in
substitution for which they are granted.

10.1   CAPITAL STRUCTURE CHANGES:

       (a)  In the event of any change  in the number of issued shares of Stock
resulting from a subdivision or consolidation of shares or other capital
adjustment, or the payment of a stock dividend or other increase or decrease of
such shares, then appropriate adjustments shall be made by the Committee with
respect to outstanding Awards and the aggregate number of shares of Stock which
may be awarded pursuant to this Plan.  Additions to Awards issued as a result of
any such change shall bear the same restrictions and carry the same terms as the
Awards to which they relate.

                                       8

 
       (b)  In the event of a change in the Stock which is limited to a change
in the designation thereof to "capital stock" or other similar designation, or
in par value to no par value, without increase or decrease in the number of
issued shares, the shares resulting from any such change shall be deemed to be
Stock within the meaning of this Plan.

11.1   IN GENERAL

       (a)  If the Company shall be the surviving or resulting corporation in
any merger, sale of assets or sale of stock, consolidation or corporate
reorganization (including a reorganization in which the holders of Stock receive
securities of another corporation), any Award granted hereunder shall pertain to
and apply to the securities to which a holder of Stock would have been entitled.
The Committee shall make such appropriate determinations and adjustments as it
deems necessary so as to substantially preserve the rights and benefits, both as
to number of shares and otherwise, of Participants under this Plan.

       (b)  If the Company shall not be the surviving corporation in any merger,
sale of assets or sale of stock consolidation or corporate reorganization
(including a reorganization in which the holders of Stock receive securities of
another corporation) involving the Company, the successor corporation shall
issue substitute options so as to preserve substantially the rights and benefits
of the Participants under this Plan.

12.1   AMENDMENTS AND TERMINATION.  The Plan shall terminate on the tenth (10)
anniversary of the Effective Date of the Plan.  The Board may at any time and
from time to time otherwise alter, amend, suspend or terminate this Plan in
whole or in part; provided, however, that (i) no such action may be taken
without stockholder approval which materially increases the benefits accruing to
Participants hereunder, materially increases the number of securities which may
be issued pursuant to this Plan (except as provided in Sections 10.1 and 11.1),
materially extends the period for granting Awards hereunder, or materially
modifies the requirements as to eligibility for participation hereunder; and
(ii) no such action may be taken, without the consent of the Participant to whom
any Award shall have been granted, which adversely affects the rights of such
Participant concerning such Award, except as such termination or amendment of
this Plan is required by statute, or rules and regulations promulgated
thereunder, or as otherwise permitted hereunder.

                            MISCELLANEOUS PROVISIONS
                            ------------------------

13.1   NON-TRANSFERABILITY.  Except by the laws of descent and distribution, no
benefit provided hereunder shall be subject to alienation, assignment or
transfer by a Participant (or by any person entitled to such benefit pursuant to
the terms of this Plan), nor shall it be subject to attachment or other legal
process of whatever nature, and any attempted alienation, assignment, attachment
or transfer shall be void and of no effect whatsoever and, upon any such
attempt, the benefit shall terminate and be of no force or effect.  During a
Participant's lifetime, Options granted to the Participant shall be exercisable
only by the Participant.  Shares of Stock shall be delivered only into the hands
of the Participant entitled to receive the same or into the hands of the
Participants authorized legal representative.

13.2   NO EMPLOYMENT RIGHT.  Neither this Plan nor any action taken hereunder
shall be construed as giving any right to any individual to be retained as an
officer, employee, director or independent contractor of the Company.

13.3   TAX WITHHOLDING.  The Company shall have the right to deduct from all
Awards paid any federal, state, local or employment taxes which it deems are
required by law to be withheld with respect to such payments.  The Participant
receiving Stock pursuant to the exercise of an Option may be required to pay to
the Company an amount required to be withheld with respect to such Stock.  At
the request of a Participant, or as required by law, such sums as may be
required for the payment of any estimated or accrued income tax liability may be
withheld and paid over the governmental entity entitled to receive the same.

13.4   FRACTIONAL SHARES.  Any fractional shares concerning Awards shall be
eliminated at the time of payment or payout by rounding down for fractions of
less than one-half (1/2) and rounding up for fractions of equal to or greater
than one-half (1/2).  No cash settlements shall be made with respect to
fractional shares eliminated by rounding.

13.5   GOVERNMENT AND OTHER REGULATIONS.  The obligation of the Company to make
payment of Awards in Stock or otherwise shall be subject to all applicable laws,
rules and regulations, and to such approvals by any government agencies as may
be deemed necessary or appropriate by the Committee.  If Stock awarded hereunder
may in certain circumstances be exempt from registration under the Securities
Act of 1933, the Company may restrict its transfer in such manner as it deems
advisable to ensure such exempt status.  The Plan is intended to comply with
Rule 16b-3 under the Securities Exchange Act of 1934, as amended.  Any provision
inconsistent with such Rule shall be inoperative and shall not affect the
validity of the Plan.  The Plan shall be subject to any provision necessary to
assure compliance with federal and state securities laws.

                                       10

 
13.6   INDEMNIFICATION.  Each person who is or at any time serves as a member of
the Board or the Committee shall be indemnified and held harmless by Integral
Systems, Inc. against and from (i) any loss, cost, liability or expense that may
be imposed upon or reasonably incurred by such person in connection with or
resulting from any claim, action, suit or proceeding to which such person may be
a party or in which such person may be involved by reason of any action or
failure to act under this Plan; and (ii) any and all amounts paid by such person
in satisfaction of judgment in any such action, suit or proceeding relating to
this Plan.  Each person covered by this indemnification shall give Integral
Systems, Inc. an opportunity, at its own expense, to handle and defend the same
before such person undertakes to handle and defend the same on such person's own
behalf.  The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under the
charter or by-laws of Integral Systems, Inc. as a matter of law, or otherwise,
or any power that Integral Systems, Inc. may have to indemnify such person or
hold such person harmless.

13.7   RELIANCE ON REPORTS.  Each member of the Board or the Committee shall be
fully justified in relying or acting in good faith upon any report made by the
independent public accountants of the Company, and upon any other information
furnished in connection with this Plan.  In no event shall any person who is or
shall have been a member of the Board or the Committee be liable for any
determination made or other action taken or any omission to act in reliance upon
any such report or information, or for any action taken, including the
furnishing of information, or failure to act, if in good faith.

13.8   GOVERNING LAW.  All matters relating to this Plan or to Awards granted
hereunder shall be governed by the laws of the State of Maryland, without regard
to the principles of conflict of laws thereof, except to the extent preempted by
the laws of the United States.

13.9   RELATIONSHIP TO OTHER BENEFITS. No payment under this Plan shall be taken
into account in determining any benefits under any pension, retirement, profit
sharing or group insurance plan of the Company.

13.10  EXPENSES.  The expenses of implementing and administering this Plan shall
be borne by the Company.

13.11  TITLES AND HEADINGS.  The titles and headings of the Articles and
Sections in this Plan are for convenience of reference only, and in the event of
any conflict, the text of this Plan, rather than such titles or headings, shall
control.

13.12  USE OF PROCEEDS.  Proceeds from the sale of Stock pursuant to Options
granted under the plan shall constitute general funds of the Company.

13.13  NON-EXCLUSIVITY OF PLAN.  Neither the adoption of the Plan by the Board
nor the submission of the Plan to the stockholders of the Company for approval
shall be construed as creating any limitations on the power of the Board to
adopt such other incentive arrangements as it may deem desirable, including,
without limitation, the granting of stock options otherwise than under the Plan,
and such arrangements may be either applicable generally or only in specific
cases.
