                       Annual Meeting of Stockholders 
                               June 30, 1998


                                PROXY STATEMENT


               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 Tuesday, June 30, 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 June 9, 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 [  ] 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 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 February 9, 
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 
Company's Articles of Amendment and Restatement to 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' terms would expire at the 1999 annual meeting of 
stockholders; Class II Directors' terms would expire at the 2000 annual 
meeting of stockholders; and Class III Directors' 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 16(a) of the Exchange Act, with the following 
exceptions:  Steven Chamberlain, a director and executive officer of the 
Company, inadvertently filed late a Form 4 for January 1997 reporting 
one transaction and a Form 5 for fiscal 1996 reporting two transactions; 
Thomas Gough, a director and executive officer of the Company, 
inadvertently filed late a Form 5 for fiscal 1996 reporting one 
transaction; Robert Sadler, a director and executive officer of the 
Company, inadvertently filed late a Form 4 for June 1997 reporting two 
transactions and a Form 5 for fiscal 1996 reporting one transaction; 
Steven Kowal, an executive officer of the Company, inadvertently filed 
late a Form 4 for June 1997 reporting one transaction and a Form 5 for 
fiscal 1996 reporting one transaction; Steven Carchedi, an executive 
officer of the Company, inadvertently filed late a Form 5 for fiscal 
1996 reporting two transactions; Elaine Parfitt, an executive officer of 
the Company, inadvertently filed late a Form 3; William Tittley, an 
executive officer of the Company, failed to file a Form 5 for fiscal 
1996 reporting one transaction; Donald Mack, an executive officer of the 
Company, failed to file a Form 5 for fiscal 1996 reporting one 
transaction.


Board of Directors and Committees

The Board of Directors met four times in the fiscal year ended September 
30, 1997.  Each of the directors attended at least 75% of all meetings 
of the Board of Directors except for Robert P. Sadler.  The Audit 
Committee and the Stock Option Committee held their meetings 
concurrently with the meetings of the Board of Directors.  The Board of 
Directors formed a Compensation Committee on May 8, 1998.  The Company 
does not have a nominating committee.

The Audit Committee, Compensation Committee and Stock Option Committee 
are comprised of Dominic A. Laiti, R. Doss McComas, and Bonnie Wachtel, 
each a non-employee director.  Prior to May 8, 1998, the Stock Option 
Committee was comprised of Bonnie K. Wachtel and Thomas L. Gough.

The Stock Option Committee administers the 1988 Stock Option Plan.  The 
Audit Committee makes recommendations concerning the engagement of 
independent public accountants, reviews with the independent public 
accountants the plan and results of the audit engagement, reviews the 
independence of the independent public accountants, considers the range 
of audit and non-audit fees and reviews the adequacy of the Company's 
internal accounting controls.  The Compensation Committee determines the 
salary and bonus for the Chief Executive and makes recommendations 
regarding compensation levels for other officers of the Company.



Director Compensation

Directors who are employees of the Company do not receive any 
compensation for their service as directors.  The Company pays each 
director who is not an employee of the Company $5,000 per year for their 
services.  Directors are granted stock options pursuant to the 1988 
Stock Option Plan.

Employment Agreements

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

Compensation Pursuant to Plans
	
ISI's Board of Directors determines the annual bonuses and salary 
awarded to Steven R. Chamberlain.  Steven R. Chamberlain determines the 
annual bonuses and salaries awarded to other executive officers on a 
discretionary basis.  Currently no formal plan exists for determining 
bonus amounts.

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 plan, 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 under 
this plan.  The maximum number of shares of Common Stock which may be 
issued pursuant to the stock plan was increased from 150,000 to 600,000 
during fiscal year 1994.  Options to purchase a total of 19,512 shares 
of Common Stock were issued and options to purchase 4,853 shares of 
Common Stock were exercised during fiscal year 1997.  Total shares 
subject to options issued and outstanding as of March 31, 1998 are 
487,575.  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.



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 600,000 to 
900,000 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 
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.


                       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.

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 the stockholders to remove any director from office without 
cause could frustrate the purposes of the proposed Staggered Board Amendment, 
upon approval of the Staggered Board Amendment, approval of such amendment 
will cause the Articles of Incorporation to be amended to provide that 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.  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 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.



                        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, 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.


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 
600,000 to 900,000, 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 6-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 600,000 
shares authorized for issuance under the Stock Option Plan, 112,425 
shares remained available for issuance upon the exercise price of stock 
options thereunder.

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 300,000 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 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, 3 
directors, 10 officers, 134 employees and 2 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 10 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 5 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 900,000 shares, of which options with respect to 487,575 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 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 NASDAQ on May 21, 1998, was $29.50 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 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 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.
