                                 MARCH 30, 1994
 
     The Notice of the 1994 Annual Meeting of Stockholders of the Corporation is
set forth on the preceding page and there is enclosed with this Proxy Statement
a form of Proxy solicited by the Board of Directors of the Corporation. The cost
of this solicitation will be borne by the Corporation. In addition to
solicitation by mail, certain of the officers and employees of the Corporation
also may solicit Proxies personally or by telephone or telegram. This Proxy
Statement is being first sent to stockholders on or about March 30, 1994. A copy
of the Annual Report to Stockholders for the year 1993 (including audited
financial statements of the Corporation) also accompanies this Proxy Statement.
 
     Only stockholders of record as of the close of business on March 18, 1994
are entitled to notice of and to vote at the 1994 Annual Meeting and/or any
adjournment thereof. The outstanding stock of the Corporation on the record date
entitled to vote consisted of 6,949,406 shares of common stock, $1 per share par
value ("Common Stock"). The holders of the outstanding shares of Common Stock
are entitled to one vote per share. All shares represented by valid Proxies
received by the Clerk of the Corporation prior to the meeting will be voted as
specified in the Proxy: if no specification is made and if discretionary
authority is conferred by the stockholder, the shares will be voted for the
election of each of the Board's nominees to the Board of Directors in proposal
1; for the approval and ratification of the amendments to the 1979 Stock Option
Plan in proposals 2 and 3; and for the selection of an auditor in proposal 4. A
stockholder giving a Proxy has the power to revoke it at any time prior to its
exercise by delivering to the Clerk of the Corporation a written revocation or a
duly executed Proxy bearing a later date, or by attendance at the meeting and
voting such shares in person.
 
     Votes cast by proxy or in person at the Annual Meeting will be tabulated by
the election inspectors appointed for the meeting and will determine whether or
not a quorum is present. The election inspectors will treat abstentions as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum but as not having been voted for purposes of determining
the approval of any matter submitted to the shareholders for a vote. If a broker
indicates on the proxy that it does not have discretionary authority as to
certain shares to vote on a particular matter, those shares will not be
considered as present and entitled to vote with respect to that matter.

Committee reviews and establishes the remuneration to be paid to the executive
officers of the Corporation, reviews the remuneration to be paid to other
officers, and acts as the administrator of the Corporation's stock option plans.
 
     During 1993, the Board of Directors held four meetings. The Audit Committee

ITEM 2. APPROVAL OF AMENDMENT TO 1979 STOCK OPTION PLAN TO INCREASE NUMBER OF
        SHARES AVAILABLE FOR ISSUANCE BY 325,000 SHARES.
 
     Description of 1979 Plan
 
     Under the 1979 Stock Option Plan (the "1979 Plan"), the Corporation may
grant options to acquire its Common Stock to officers and other key employees of
the Corporation and its subsidiaries. As of December 31, 1993, a total of 12,754
of the 1,130,000 shares previously reserved for issue under the 1979 Plan remain
available for future grants of options. Approximately 200 employees, including
officers of the Corporation and its subsidiaries, are presently eligible to
participate in the 1979 Plan. During 1993, options for a total of 345,250 shares
were issued under the 1979 Plan with an average exercise price of $39.54 per
share.
 
     Under the terms of the 1979 Plan, the grantees, the number of shares
covered by each option, the exercise price of each non-qualified option (which
may not be less than $1.00 per share) and the duration of options (which may not
exceed ten years plus one day) are determined by the 1979 Plan's administrator,
the Compensation Committee of the Board of Directors (the "Committee"). Only
non-qualified options may now be granted under the 1979 Plan. Options may be
exercised not only with cash, but also with Common Stock of the Corporation. The
Compensation Committee usually provides either (i) that an option may be
exercised only in part, on a cumulative basis, during each of the five years
following the date of grant; or (ii) if the option is made immediately
exercisable in full, that the Corporation has the right to repurchase a
decreasing portion of any shares purchased upon exercise during the five years
following the date of grant. In any event, the option may not be transferred by
the grantee, and it may be exercised only while the grantee is an employee of
the Corporation or of a subsidiary, or within 30 days after termination of his
employment, or by an individual's estate for a period of 90 days after his
death. The termination date of the 1979 Plan is February 15, 1997.
 
     There are no federal income tax consequences to an option holder when a
non-qualified option is granted. Upon exercise of a non-qualified option, the
option holder recognizes taxable compensation in an amount equal to the fair
market value of the stock on the date of exercise minus the exercise price, and
the Corporation is allowed a corresponding compensation deduction. If the
Corporation has the right to repurchase the shares acquired under a
non-qualified option, the taxable events in connection with the exercise of the
option are postponed until the Corporation's repurchase rights expire.
 
     In addition to stock options, the Committee may award performance units
("Performance Units") under the Plan from time to time as it deems appropriate.
A performance unit plan permits an employee to be awarded cash, stock options on
Common Stock, or some combination thereof, contingent upon the Corporation
achieving certain performance goals. The Committee has broad discretion to
determine the nature of the performance objectives, which will be based upon a
specific dollar amount of growth or on a percentage rate of improvement in such
factors as the Corporation's (or a subsidiary's) earnings per share, income,
return on equity, or such other measures related to the growth or improvement of
the Corporation or its subsidiaries as the Committee determines. The Committee
will also determine the length of the period in which the stipulated performance
is to be achieved (the "Award Period"), whether and to what extent the
performance objectives have been attained, as well as the value of the
Performance Units earned. The Committee may establish a stated value for each
Performance Unit. If an employee ceases employment because of disability or
death prior to the end of an Award Period, any Performance Units he or she might
ultimately have earned will be paid at the end of the Award Period, as
determined by the Committee. Upon termination of employment for any other
reason, Performance Units and all of an employee's rights associated therewith
will terminate, unless the Committee in its discretion determines otherwise. The
Committee has not yet granted any Performance Units under the 1979 Plan.
 
                                        9
<PAGE>   11
 
     In general, for tax purposes, a participant will include in his or her
income the fair market value of a Performance Unit award when the award is paid
out to the participant. The amount of ordinary income recognized by the
participant is deductible by the Company. For financial statement purposes, the
grant of Performance Units will give rise to an employee compensation cost to be
charged to the operations of the Company. Such cost will be equal to the cash
amount or the fair market value of the number of shares or options to be awarded
at the end of the Award Period, less any payment required to be made by the
recipient (e.g., the exercise price in the event the Performance Units are to be
paid out in options), should the performance conditions be met.
 
     The Board of Directors may at any time terminate the 1979 Plan, or amend
it, except with respect to certain matters which require the approval of the
Corporation's stockholders. No options or Performance Units may be granted under
the 1979 Plan after its termination.
 
     Proposed Amendment
 
     On February 17, 1994, the Corporation's Board of Directors amended the 1979
Plan, subject to the approval of the stockholders of the Corporation at the 1994
Annual Meeting, to increase the number of shares available for issuance upon
exercise of options or pursuant to the pay-out of Performance Units by 325,000
shares, representing approximately 4.7% of the Corporation's outstanding stock
(see Item 3 for an additional proposed amendment to the 1979 Plan).
 
     The Board of Directors has taken such action, subject to stockholder
approval, to provide for the availability of additional shares in connection
with future grants of stock options and/or Performance Units, based upon its
belief that stock options and Performance Units are desirable and effective
employment incentives for the retention of key employees, as well as to attract
additional key employees to the Corporation.
 
     The Board of Directors recommends that you vote FOR the proposal to ratify
and approve the amendment to the 1979 Plan to increase by 325,000 shares the
number of shares of Common Stock available under the 1979 Plan. Under the terms
of the 1979 Plan, the increase in the number of shares of Common Stock available
for issuance under the 1979 Plan requires the affirmative vote of the holders of
a majority of the outstanding shares of Common Stock, or 3,474,704 shares.
 
ITEM 3. APPROVAL OF AMENDMENT TO 1979 STOCK OPTION PLAN TO LIMIT NUMBER OF
        SHARES WHICH MAY BE ACQUIRED BY ANY PARTICIPANT IN ANY YEAR TO 100,000
        SHARES.
 
     The Omnibus Budget Reconciliation Act of 1993 added Section 162(m) to the
Internal Revenue Code of 1986. Under Section 162(m), the allowable deduction for
compensation paid or accrued with respect to the chief executive officer and
each of the four most highly compensated employees of a publicly held
corporation is limited to no more than $1 million per year for fiscal years
beginning on or after January 1, 1994. This limitation does not apply to
compensation attributable to stock options or Performance Units if, among other
things, the 1979 Plan includes limits on grants of options and Performance Units
to plan participants so that the number of shares of Common Stock which can be
acquired by a participant in a defined time period is limited.
 
     To comply with Section 162(m), on February 17, 1994, the Corporation's
Board of Directors amended the 1979 Plan to provide that no participant in the
1979 Plan may be granted stock options or Performance Units in any year to
acquire in the aggregate more than 100,000 shares of Common Stock. The Board of
Directors desires to amend the 1979 Plan to comply with Section 162(m) to permit
the full amount of compensation attributable to stock options or Performance
Units to be available as an income tax deduction to the Corporation.

     The Board of Directors recommends that you vote FOR the proposal to ratify
and approve the amendment to the 1979 Plan to comply with Section 162(m) by
limiting the number of stock options and Performance Units which may be granted
to any participant in any year to permit the acquisition by any participant of
no more than 100,000 shares of Common Stock in the aggregate. Approval of this
amendment requires the affirmative vote of the holders of a majority of the
number of shares represented in person or by Proxy at the Annual Meeting.
 
ITEM 4. SELECTION OF AN AUDITOR.
 
     It is proposed that the stockholders select an independent auditor for the
Corporation for the current fiscal year, which ends December 31, 1994. The
persons named in the Proxy intend to vote in favor of selecting Coopers &
Lybrand unless otherwise directed in the Proxy. The firm became auditors for the
Corporation in 1974.
 
     Although the Corporation is not required to submit the selection of its
auditor to a vote of stockholders, the Board of Directors of the Corporation
believes it is sound policy and in the best interests of the stockholders to do
so. In the event a majority of the votes cast are against the selection of
Coopers & Lybrand, the Board will consider the vote and the reasons therefor in
future recommendations on the selection of an auditor for the Corporation.
 
     A representative of Coopers & Lybrand is expected to be present at the
stockholders' meeting with the opportunity to make a statement if desired, and
is expected to be available to respond to appropriate questions from
stockholders who are present at the meeting.

(1)  The Company has issued no SARs (stock appreciation rights).
 
(2)  All options were granted under the Company's 1979 Stock Option Plan, and
     each option is exercisable for one share of Common Stock, which may be
     purchased upon exercise with either cash or Common Stock. The options have
     a duration of ten years and one day, and are immediately exercisable,
     subject to the Company's right to repurchase a decreasing proportion of any
     shares purchased upon exercise during the first five years from the date of
     grant in the event the employee leaves the Company or desires to sell the
     shares. Such repurchase rights in the Company terminate in the event of a
     merger, consolidation or sale of all the assets by the Company, or in the
     event another entity, person or group acquires 30% or more of the
     outstanding voting shares of the Company. Options may not be transferred by
     an option holder (other than by the laws of descent or distribution), may
     be exercised only while the holder is an employee of the Company or a
     subsidiary, or within 30 days after termination of employment, or by the
     holder's estate for a period of 90 days after his death.
 
(3)  The potential realizable dollar value of a grant is the product of (a) the
     difference between: (i) the product of the per-share market price on the
     date of grant and the sum of 1 plus the adjusted stock price appreciation
     rate (the assumed rate of appreciation compounded annually over the term of
     the option); and (ii) the per-share exercise price of the option; and (b)
     the number of shares underlying the grant at fiscal year-end.

PENSION PLAN
 
     Employees based in Watertown, Massachusetts; Phoenix, Arizona; Campbell,
California; and Bellevue, Washington may at their election participate in the
Company's defined benefit retirement plan ("Retirement Plan") after attaining
age 21 and completing one year of service. No benefits vest under the Retirement
Plan until an employee has five years of participation, at which time the
employee becomes 100% vested. An employee must contribute at least 1% of base
salary in order to accrue benefits under the Retirement Plan. The benefits
payable upon retirement vary with the years of service and level of compensation
while participating in the Retirement Plan. Upon retirement, participants also
receive the total of their own contributions to the Retirement Plan plus the
earnings thereon. The following table shows the estimated annual
Company-provided pension benefits payable to a participant at normal retirement
age (age 65) in the Retirement Plan.

(1) Effective November 1, 1989, no more than $200,000 (as adjusted from time to
    time by the Internal Revenue Service) of cash compensation may be taken into
    account in calculating contributions under the Retirement Plan. In 1993, the
    cash compensation limit was $235,840.
</TABLE>
 
     Under the terms of the Retirement Plan, only the amount shown as "Salary"
in the Summary Compensation Table is covered under "Base Salary" above. The
fixed monthly retirement benefit of a participant retiring at normal retirement
age (assuming payment is made on a life annuity basis) is determined by the
following formula: (i) for years prior to January 1, 1986 -- one half of one
percent of the first $550 of base monthly salary as of January 1, 1985, plus one
and one-quarter percent (1.25%) of the balance of base monthly salary as of that
date, that sum being multiplied by the number of prior years of service; plus
(ii) for each year after December 31, 1985 through December 31, 1988 -- one half
of one percent (0.5%) of the first $550 of base monthly salary as of January 1st
of such year plus one and one-quarter percent (1.25%) of the balance of base
monthly salary; plus (iii) for each year after December 31, 1988 -- one and
one-quarter percent (1.25%) of base monthly salary as of January 1st of that
year. Fixed retirement benefits are not subject to deduction for Social Security
benefits or other benefits received by participants.
 
     Executive officers named in the Summary Compensation Table have been
credited with the following years of service, and would receive the following
estimated annual benefit at normal retirement age (65): Mr. Goldstein, 33.6
years, $85,447; Mr. Katz, 44.4 years, $53,590; Mr. Kachadurian, 13 years,
$54,988; Mr. Papastavros, 37.2 years, $46,881; and Mr. Korn, 4.3 years, $34,326.
 
REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE
COMPENSATION
 
     The Board of Directors appoints each year from among its members a
Compensation Committee (the "Committee"). The Committee, which currently
consists of six non-employee directors (all of whom are "disinterested persons"
under Rule 16b-3 of the Securities Exchange Act of 1934), is responsible for
reviewing and establishing the compensation of the executive officers of the
Company, and for authorizing grants under the Company's 1979 Stock Option Plan.
The Committee has furnished this report concerning compensation of executive
officers for the fiscal year ended December 31, 1993.
 
     The compensation program for executive officers involves consideration of
cash compensation and the granting of options to acquire the Company's Common
Stock.
 
                                       15
<PAGE>   17
 
     Cash Compensation
 
     Cash compensation of executive officers is structured to include base
salary and, based on the achievement of performance objectives, a cash bonus.
The Company's objective is to pay a fair and competitive base salary to all
employees and to keep the growth of salary levels at or near the rate of
inflation. The Company determines the competitiveness of its base salary levels
in relation to other companies engaged in its industry, represented by those in
the "peer group" Index set forth in this Proxy Statement, or similar industries.
The Committee believes that the base salary paid to the Company's executive
officers falls within the median of the range of compensation paid by the "peer
group" companies. Salary levels for executive officers are usually established
in the early part of the fiscal year for that fiscal year.
 
     The policy of the Company is to pay cash bonuses based upon the achievement
of specified corporate, business unit and individual performance objectives. The
cash bonuses listed in the Summary Compensation Table earned by executive
officers in 1991 and 1992, as well as by other senior officers, were earned
under the Company's Managerial Bonus Program. The Managerial Bonus Program
considers both quantitative and qualitative performance. Quantitative
performance focuses upon two measurements: earnings before interest and taxes
(EBIT) achieved by the business unit(s) for which the executive officer has
major responsibility or involvement, and EBIT return on the average capital
employed by such business unit(s) during the year. Qualitative performance
focuses primarily on the degree to which the officer has participated in and
contributed to the achievement of specified individual, divisional, departmental
or corporate non-financial objectives.
 
     Budgeted amounts for EBIT and EBIT return on average capital employed are
established for each business unit early in each fiscal year. At the same time,
a corresponding cash bonus target is established for each executive officer
based upon the budgets of the business unit(s) for which the officer has major
managerial responsibility or involvement. The cash bonus actually awarded,
determined early in the next fiscal year by the Committee, depends upon the
extent to which the actual performance of the business unit(s) for which the
officer has responsibility or involvement meets or exceeds the budgeted amounts,
and upon the degree of success in achieving the qualitative objectives.
 
     The Committee reserves the right to make discretionary bonus awards in
appropriate circumstances under which an executive officer might merit a bonus
based on other considerations.
 
     Securities and Exchange Commission (SEC) regulations require that the
Committee discuss the basis for the 1993 compensation reported for the Chief
Executive Officer, Mr. Goldstein, and to discuss the relationship between the
Company's performance during 1993 and his compensation. Mr. Goldstein's base
salary (and the base salary of the other corporate executive officers) was
established by the Committee in February 1993, and reflected a 5.5% increase,
consistent with the Committee's salary policy. This increase was implemented as
of July 1, 1993.
 
     The quantitative performance targets of the Managerial Bonus Program were
not achieved in 1993. As a result, the Compensation Committee, in concurrence
with management's recommendation, chose not to award cash bonuses to Mr.
Goldstein or any of the Company's executive officers for 1993.
 
     Stock Options
 
     The Committee believes that stock options are an appropriate mechanism to
provide senior management with a long-term incentive to strive for the continued
growth and success of the Company. The Company's stock option policy,
established by the Committee, is to recognize employee leadership and
significant contribution to the Corporation, regardless of the employee's level.
The Committee also believes that
 
                                       16
<PAGE>   18
 
ownership of the Company's stock by management promotes the enhancement of
shareholder value by creating a greater communality of interest among
shareholders and management. For these reasons, the Committee has used in the
past, and expects to use in the future, the Company's 1979 Stock Option Plan as
an element of its executive compensation program. In 1993, the Compensation
Committee met on August 25th and awarded Mr. Goldstein a stock option grant of
50,000 shares, based upon a qualitative assessment of his performance since the
last stock option grant to him in 1991, including factors such as growth in the
Company's revenues and profitability, success in achieving annual goals, and
success in hiring additional key employees.
 
     Compliance with Internal Revenue Code Section 162(m)
 
     Section 162(m) of the Internal Revenue Code enacted in 1993, generally
disallows a tax deduction to a public company for compensation in excess of $1
million paid to the company's chief executive officer and four other most highly
compensated executive officers. Certain types of performance-based compensation,
such as that available under the Company's 1979 Stock Option Plan, will not be
subject to the deduction limit if certain requirements set forth in Section
162(m) are met. The Company currently intends to structure compensation to
executive officers arising out of the 1979 Plan in a manner that complies with
the new statute.

FIVE-YEAR SHAREHOLDER RETURNS COMPARISON
 
     The SEC requires that the Company include in this proxy statement a
line-graph presentation comparing cumulative, five-year return to the Company's
shareholders (based on appreciation of the market price of the Company's Common
Stock) on an indexed basis with (i) a broad equity market index and (ii) an
appropriate published industry or line-of-business index, or peer group index
constructed by the Company. The following presentation compares the Company's
Common Stock price in the five year period from December 31, 1988 to December
31, 1993, to the S&P 500 Stock Index and to a "peer group" index over the same
period. The "peer group" index consists of the common stock of Calgon Carbon
Corporation, Osmonics, Inc., Pall Corporation and United States Filter
Corporation. These corporations are involved in various aspects of the water
treatment or liquids separations businesses. The presentation assumes that the
value of an investment in each of the Company's Common Stock, the S&P 500 Index,
and the peer group index was $100 on December 31, 1988, and that any dividends
paid by any constituent company (none have been paid by the Company) were
reinvested in the same security.

DIRECTOR COMPENSATION
 
     In 1993, each director who is not an employee of the Company received an
annual retainer of $5,600, plus a fee of $850 for each regular board meeting
attended. Commencing in 1994, the annual retainer has been adjusted to $8,000
and the meeting fee to $1,000. In addition, under the Company's 1986 Stock
Option Plan for Non-Employee Directors ("1986 Plan"), each person who is not an
employee of the Company or any of its subsidiaries and who is elected a Director
of the Company is entitled to receive an option for 1,000 shares of Common Stock
upon his initial election, an option to acquire 1,000 additional shares
immediately upon completion of each of his next four successive years in office,
and an option to acquire 500 additional shares immediately upon completion of
each of his next five successive years in office. Thus, under the 1986 Plan, a
Director is entitled to receive options for a maximum of 7,500 shares of Common
Stock. Options granted under the 1986 Plan have an exercise price equal to the
market price on the date of grant, do not become exercisable until the
expiration of six months from the date of grant, and thereafter may be exercised
only during certain "window" periods. Options granted under the 1986 Plan expire
ten years after the date of grant, and terminate 30 days after the holder ceases
to be a Director, or 90 days following a Director's death.

                              CERTAIN TRANSACTIONS
 
     Because certain options granted under the Corporation's 1973 Non-Qualified
Stock Option Plan, which expired in 1983, were not eligible to be treated by
their holders as incentive stock options, the Board of Directors agreed to
permit officer-employees exercising non-qualified options granted prior to
January 1, 1976 to borrow from the Corporation up to an aggregate of $600,000 in
connection with the payment of taxes and other expenses incurred by them in
exercising the options. These loans bear interest at the rate of 5% per annum,
and their repayment is secured by the pledge of a least 80% of the stock so
purchased. On February 26, 1987 the Compensation Committee of the Board of
Directors extended the maturity of these loans until 1994. Mr. Goldstein and
three other officers borrowed funds pursuant to this loan facility. Two of the
other officers subsequently paid off their loans. In 1993, the largest
outstanding indebtedness of Mr. Goldstein was $141,560. Mr. Goldstein paid the
outstanding balance of the loan on December 14, 1993.

                              IONICS, INCORPORATED

                             1979 Stock Option Plan
                             ----------------------

                      As Amended through February 17, 1994
                      ------------------------------------

1.   Purposes of Plan.
     ----------------

     This 1979 Stock Option Plan (hereinafter called the "Plan") of Ionics,
Incorporated (hereinafter called the "Company") is intended to advance the
interests of the Company (and its subsidiaries) by providing a means whereby
key employees of the Company, that is, those who are largely responsible for
its management and its technical and business success, and are expected to
continue in this role, may be offered incentives in addition to the other
incentives which they may hold, such as pensions, etc.

2.   Definitions.
     -----------

     2.1  "Subsidiaries" or "Subsidiary" shall mean a corporation,
partnership or other entity whose controlling stock or other ownership
interest is owned directly or indirectly by the Company.

     2.2  A "key employee" shall mean an employee of the Company or of any
of its Subsidiaries who is engaged in an important executive, administrative
or technical function who is classified by the Administrators of the Plan as
such within the purposes of the Plan.

3.   Effective Date and Duration.
     ---------------------------

     The Plan will become effective immediately upon its adoption by the
Board of Directors of the Company, subject, however, to approval by the
holders of a majority of the outstanding shares of its capital stock having
voting rights present at the meeting when the matter was acted upon.  The
Plan shall remain in effect until the close of business on February 15, 1997
(the "Termination Date").

4.   Stock Subject to the Plan.
     -------------------------

     Subject to adjustment as provided hereinbelow, the total aggregate
number of shares of Common Stock, One Dollar ($1) per share par value
(hereinafter "Common Stock"), of the Company which are to be issued and
delivered upon exercise of options granted pursuant to this Plan
(hereinafter called the "Options" and each singly an "Option") or pursuant
to the earn out of Performance Units under this Plan, shall not exceed
1,455,000 shares of said Common Stock.  Such shares may either be authorized
and unissued shares of Common Stock or issued shares of Common Stock which
shall have been reacquired by the Company and held as treasury shares.  In
the event that any Options granted under the Plan shall be surrendered to
the Company or shall terminate, lapse or expire for any reason without
having been exercised in full, the shares not purchased under such Options
shall be available again for the purposes of issuance pursuant to the Plan.

<PAGE>   23


     In the event that the outstanding shares of the Common Stock of the
Company are hereafter increased or decreased or changed into or exchanged
for a different number or kind of shares, or other securities of the Company
or of another corporation, by reason of reorganization, merger,
consolidation, recapitalization, reclassification, stock split-up,
combination of shares, or dividends payable in stock, corresponding
adjustments as determined by the Board of Directors in their sole discretion
to be appropriate shall forthwith be made in the Option price and in the
number and kind of shares for the purchase of which Options may theretofore
or thereafter be granted under the Plan; provided, however, the aggregate
total Option price of Options then outstanding and unexercised shall not be
changed thereby.

5.   Administration of the Plan.
     --------------------------

     The Plan shall be administered by the Board of Directors of the Company
or such committee composed of its Directors as may be delegated this duty
and function by resolution of the Board of Directors (said Board or said
Committee, as the case may be, being hereinafter referred to as the
"Administrators").  The Administrators shall be comprised of, to the extent
required by applicable regulations under Section 162(m) of the Code, two or
more outside Directors as defined in applicable regulations thereunder and,
to the extent required by Rule 16b-3 promulgated under the Securities
Exchange Act of 1934 or any successor provision, disinterested Directors.  A
majority of the Administrators acting upon a particular matter shall have no
personal interest in the Option or matter with which they are concerned.

     Subject to the express provisions of the Plan, the Administrators
acting by a majority of their number at a meeting or by written consent
shall have plenary authority in their discretion to grant Options under the
Plan, and in relation thereto to determine from time to time those officers
or employees of the Company or of its Subsidiaries who are to receive
Options, the number of shares to be optioned to each, the Option price
(which shall not be less than the par value of the stock subject to the
Option) and the terms and conditions upon which the Options are to be
granted, which need not be identical; including, without limitation,
requirements that an exercise of the Option may be conditioned in whole or
in part upon duration of the optionee's employment, his attainment of
specified performance criteria, his refraining from competitive activities
and other conditions.  Options may be granted at any time prior to
termination of the Plan and the Options granted may extend beyond the
Termination Date.

     Subject to the express provisions of the Plan, the Administrators may
(1) construe the respective stock Option agreements and the Plan, prescribe,
amend, and rescind rules and regulations relating to the Plan and make all
other determinations necessary or advisable for administering the Plan, and
(2) correct any defect or supply any omission or reconcile any inconsistency
in the Plan or in any stock Option agreement and in the manner and to the
extent they shall deem expedient to carry it into effect and (3) constitute
and appoint a person or persons selected by them to execute and deliver in
the name and on behalf of the Administrators all such agreements,
instruments and other documents (including without limitation of the

                                     - 2 -
<PAGE>   24

generality of the foregoing documents evidencing amendments of individual
stock Options and other actions delegated to the Administrators by the votes
of the Board of Directors adopted at their meeting on February 18, 1982,
relating to "incentive stock options").

     The Administrators shall have the authority in their discretion to
determine from time to time those officers or employees of the Company or of
its Subsidiaries who are eligible to receive Performance Units, as
hereinafter defined.  In connection therewith the Administrators shall have
the authority to prescribe the number of Performance Units to be granted to
any key employee and all terms thereof and to adopt, amend and rescind rules
and regulations for the administration of Performance Units.

6.   Persons to whom Options and Performance Units may be Granted.
     ------------------------------------------------------------

     Only persons who are officers of, or who are "key employees" of the
Company or any of its Subsidiaries, and who accept an Option or Performance
Unit granted hereunder, as the case may be, and subject to all of the terms
and conditions of this Plan, may be granted any Options or Performance Units
under this Plan.  During any one-year period, no individual shall be granted
Options and/or Performance Units which could result in the issuance to such
individual of more than 100,000 shares of Common Stock.

7.   The Option Price.
     ----------------

     The price payable upon exercise of an Option granted hereunder (the
"Option Price") shall be an amount as specified by the Administrators which
shall not be less than the par value of the stock which is subject to the
Option and which shall be paid upon exercise of the Option (1) in cash, (2)
with shares of the Company of the same class as the shares issuable upon
exercise of the Option, previously acquired by the optionee and having an
aggregate fair market value equal to the aggregate Option Price payable, or
(3) in any combination of cash and of such shares so valued.  In the event
such shares are delivered to pay all or a portion of the Option Price -

     (a)  such shares shall be valued at the closing price for such stock on
          the American Stock Exchange or other exchanges or markets where
          such shares are primarily traded, as reported on the date of such
          delivery of the shares, and

     (b)  a number of the shares being issued upon exercise of the Option
          which is equal to the number of shares of such stock delivered in
          payment of the Option Price shall be issued free from repurchase
          rights of the Company under said Plan or stock Option agreement
          evidencing the Option.

8.   The Duration of the Options.
     ---------------------------

     The duration of the Options granted hereunder shall be as determined by
the Administrators but shall not exceed a period of ten years from the date
of grant.  Notwithstanding the preceding sentence, the duration of Options
not designated as Incentive Stock Options pursuant to Section 17 may be a
period of ten years and one day from the date of grant.

                                     - 3 -
<PAGE>   25



9.   Nontransferability of Options.
     -----------------------------

     No Option granted under the Plan shall be encumbered, assigned, or
otherwise transferred, and an Option may be exercised during the lifetime of
the Optionee only by such person, and the stock Option agreement covering
the Option shares shall so provide.

10.  Exercise of Options.
     -------------------

     The exercise, in whole or in part, of any Option granted under the Plan
shall be :

     (a)  subject to compliance of all conditions or restrictions stated in
          Section 11 of this Plan or imposed at the time the Option is
          granted, and

     (b)  exercisable only by the employee to whom granted and while he
          remains in the employment of the Company or any of its
          Subsidiaries, except that -

          (1)  if the employee holding the Option ceases to remain in such
               employment for any reason other than his or her voluntary
               termination or his or her being terminated by the Company (or
               its Subsidiary employing said employee) because of his
               malfeasance, violation of this or any other agreement with
               the Company (or its employing Subsidiary), or other like
               justifiable cause, the employee shall have the right within
               thirty (30) days after said termination to exercise the
               Option to the extent it would have been exercisable by the
               employee immediately before the employee's termination, and

          (2)  if the employee holding the Option shall die while in said
               employment or within said 30-day period after its termination
               as described in sub-paragraph (1) above, the Option, to the
               extent exercisable by said employee at the time of his death,
               may be exercised within ninety (90) days after his death by
               the executor or administrator of the employee's estate.

     Options shall be exercised in each instance by the person entitled to
exercise them by giving written notice of exercise to the Company (to its
Treasurer) substantially in the form of Exhibit A annexed hereto and
tendering payment of the entire Option Price payable.

     Unless the shares deliverable upon exercise of Options are registered
or qualified for public sale by an effective Registration Statement of the
Company under the Securities Act of 1933, as amended (or any superseding
law) and are registered or qualified for sale under all applicable state
securities laws, the person to whom the stock is issued and delivered
hereunder shall confirm to the Company that the recipient is purchasing the
shares for investment and not with a view to effecting any distribution or
resale of the shares.

     In no instance may an Option be exercised for less than one full share
of the stock.

          and upon the following events:

     (a)  if the employee issued the Option shall cease to be an employee of
          the Company or of any of its Subsidiaries because of the
          employee's voluntary termination of said employment or his being
          terminated therefrom because of his malfeasance, violation of this
          or any other agreement with the Company or said Subsidiary for
          like justifiable cause, and/or

     (b)  before the participant may sell or transfer the stock in any
          manner, whether voluntarily, by action of law or otherwise.

          by the Company at any time within thirty (30) days after it has
          notice of any such event.  At the closing of said purchase (which
          shall be held on the fifth business day following the Company's

          elected to so purchase the shares) the Company shall pay the
          purchase price to the holder against its receipt of delivery of

          restriction, but unless said stock has been registered or
          qualified for public sale under an effective Registration
          Statement or other authorization under the Securities Act of 1933,
          as amended (or under any superseding law) and qualified for public
          sale under any applicable state securities laws, the holder shall
          not so sell or transfer without prior written notice to the
          Company and furnishing to the Company an opinion of legal counsel
          or of said regulatory authority, satisfactory to the Company, that
          no such registration or qualification of the stock is required in
          the circumstances.

     11.2 Each stock certificate representing stock issued upon exercise of
          an Option hereunder shall bear such legend referring to these
          restrictions as the Company may require, and it shall not transfer
          ownership of such stock on its records except upon compliance with
          these restrictions.

12.  Stock Option Agreement Required.
     -------------------------------

     Each stock Option granted under the Plan shall be evidenced by a "Stock
Option Agreement" between the Company and the employee granted the Option,
to be in such form as the Administrators in granting the Option shall
determine, provided that said Stock Option Agreement shall in any event
include an undertaking on the part of the Employee to whom the Option is
granted (the "Optionee") that in consideration for the grant of such Option,
the Optionee will not at any time during his employment by the Company or by
any of its Subsidiaries (as defined in the Plan) or within two (2) years
following the date of termination of said employment, without the written
consent of the Company, directly or indirectly, accept employment from, or
engage in any work or activities as an employee, officer, Director, agent,
consultant, partner, proprietor or principal stockholder for any other
corporation, person or entity which is substantially competitive to the
business in which the Company or its Subsidiaries are then engaged.

13.  Effect of the Option.
     --------------------

     The grant of an Option under the Plan shall not entitle the Optionee to
have or claim any rights of a stockholder of the Company (whether as to
dividends, voting rights or otherwise).

     Neither the grant of an Option nor the making of any Stock Option
Agreement under this Plan shall confirm upon the Optionee any right with
respect to continuation of his or her employment nor shall it affect or
restrict the right of the Company, any Subsidiary of it, or any assuming
Company, or any successor of either of them employing the Optionee to
terminate such employment at any time.

14.  Termination, Suspension, Amendment or Modification of the Plan.
     --------------------------------------------------------------

     The Board of Directors of the Company may at any time amend, alter,
suspend or terminate the Plan provided that:

     (a)  No change shall be made which, in the judgment of its Board of
          Directors, will have a material adverse effect upon any Option
          previously granted under this Plan unless the consent of the
          Optionee is obtained in writing.

                                     - 6 -


<PAGE>   28

     (b)  Without the approval by the holders of a majority of the
          outstanding shares of its capital stock having voting rights,

          (1)  the maximum number of shares reserved for issuance upon the
               exercise of Options under the Plan may not be changed; and

          (2)  the classes of employees to whom Options may be granted under
               the Plan may not be changed.

15.  Merger, Consolidation or Sale of the Entire Business of the Company.
     -------------------------------------------------------------------

     If, prior to the expiration of the Plan, or the period of restriction
during which the Company may have or may obtain rights to repurchase stock
issued hereunder pursuant to Section 11 of the Plan, the Company shall merge
with, consolidate in or with, or sell all or substantially all of its assets
and business to another corporation or entity (other than a company or
entity which continues under the control of the same persons who were the
stockholders or owners of the Company immediately prior to the event), all
Options then outstanding shall become subject to exercise in full and all of
said repurchase rights of the Company shall terminate as of the effective
date of said transaction.

16.  Optionee Shall Comply with Applicable Laws and Regulations upon Exercise.
     ------------------------------------------------------------------------

     Upon exercise of any Option granted hereunder, the person exercising
the Option shall file any and all reports if any, required of such person
under the Securities Exchange Act of 1934, as amended, or otherwise.

17.  Incentive Stock Options.
     -----------------------

     The special terms and conditions of this Section 17 shall apply to
Stock Options granted hereunder which meet any of the following requirements
("Incentive Stock Options"):

          (a)  Options considered under the Internal Revenue Code to have
               been granted on or after January 1, 1981, and before August
               14, 1981, as to which the Optionee consents in writing to the
               application of this Section 17; and

          (b)  Options granted on or after August 14, 1981, and before
               February 18, 1982, which the Administrators designate in the
               Stock Option Agreement as Incentive Stock Options, and as to
               which the Optionee consents in writing to the application of
               this Section 17; and

          (c)  Options granted on or after February 18, 1982, which the
               Administrators designate in the Stock Option Agreement as
               Incentive Stock Options.

     The following special terms and conditions (in all of which, any
reference to the date of grant of a Stock Option shall mean the date on
which the Stock Option is considered to have been granted under Sections 421

                                     - 7 -

<PAGE>   29

through 425 of the Internal Revenue Code and the regulations issued
thereunder) shall apply to all Incentive Stock Options:

     17.1 OPTION PRICE.  The Option Price shall be not less than the fair
          market value of the stock covered by the Option, determined as of
          the date of grant of the Option.

     17.2 PRIOR OUTSTANDING OPTION.  No Incentive Stock Option may be
          exercised while there remains outstanding, within the meaning of
          Section 422A(c)(7) of the Internal Revenue Code, any other
          Incentive Stock Option which was granted at an earlier date to the
          Optionee to purchase stock in this Corporation or in any other
          corporation which is on the date of grant of the later Option
          either a parent or subsidiary corporation of this Corporation, or
          a predecessor corporation of any of such corporations.  The Stock
          Option Agreement for every Incentive Stock Option shall include a
          provision to this effect.  The two preceding sentences shall have
          no application to any Incentive Stock Option granted after
          December 31, 1986.

     17.3 NO FURTHER GRANTS.  No Option granted after February 15, 1989,
          shall be designated an Incentive Stock Option.

     17.4 TEN PERCENT STOCKHOLDER.  If any Optionee to whom an Incentive
          Stock Option is to be granted pursuant to the provisions of the
          Plan is on the date of grant the owner (as determined under
          Section 424(d) of the Internal Revenue Code) of stock possessing
          more than 10% of the total combined voting power of all classes of
          stock of this Corporation or any of its subsidiaries, then the
          following special provisions shall be applicable to the Option
          granted to such individual:

          (i)  The Option Price per share of stock subject to such Incentive
               Stock Option shall not be less than 110% of the fair market
               value of one share of stock on the date of grant; and

          (ii) The Option shall not have a term in excess of five (5) years
               from the date of grant.

     Except as modified by the preceding provisions of this Section 17, all
the provisions of the Plan shall be applicable to the Incentive Stock
Options granted hereunder.

18.  SPECIAL BONUS GRANTS.  The Administrators may, but shall not be
required to, grant in connection with any Option which is not designated an
Incentive Stock Option a special bonus in cash in an amount not to exceed
the combined federal and state income tax liability incurred by the Option
holder as a consequence of his acquisition of stock pursuant to the exercise
of the Option, and payment of the bonus; payable, at the discretion of the
Administrators, in whole or in part to federal and state taxing authorities
for the benefit of the Option holder at such time or times as withholding
payments of such income tax may be required, and the remainder, if any, to
be paid in cash to the Optionee at the time or times at which he is required
to make payment of such tax.  In the event that an Option with respect to

                                     - 8 -

<PAGE>   30

which a special bonus has been granted becomes exercisable by the personal
representative of the estate of the Optionee in accordance with Section 10,
the bonus shall be payable to or for the benefit of the estate in the same
manner and to the same extent as it would have been payable to or for the
benefit of the Optionee had he survived to the date of exercise.  A special
bonus may be granted simultaneously with a related Option, or granted
separately with respect to an outstanding Option granted at an earlier date.
In the case of an Optionee who is an officer or a director of the Company,
an Option with respect to which a special bonus is granted may be exercised:

     (a)  no earlier than six months after the date on which the bonus is
          granted; provided, however, that this limitation shall not apply
          in the event that the Optionee dies or becomes disabled before the
          expiration of six months after the date on which the bonus is
          granted; and

     (b)  only within one of the following:

          (i)   a period beginning on the third business day and ending on
                the twelfth business day following the release for
                publication by the Company of a quarterly or annual summary
                statement of its sales and earnings; or

          (ii)  a period beginning on the first day and ending on the
                thirtieth day following the date of approval by the
                stockholders of the Company of (x) any consolidation or
                merger of the Company in which the Company does not survive
                as an independent, publicly owned corporation, or pursuant
                to which shares of Common Stock would be converted into
                cash, securities, or other property (other than a merger in
                which the holders of Common Stock immediately before the
                merger have the same proportionate ownership of common stock
                of the surviving corporation after the merger), or (y) a
                transfer of all or substantially all of the assets of the
                Company (other than a transfer to a subsidiary corporation
                controlled by the Company), or (z) the liquidation or
                dissolution of the Company; or

          (iii) a period beginning on the first day and ending on the
                thirtieth day following (x) the acquisition of beneficial
                ownership of thirty percent (30%) or more of the outstanding
                voting shares of the Company, whether in one transaction or
                a series of transactions, by another corporation, entity or
                person or group of corporations, entities or persons
                theretofore beneficially owning less than thirty percent
                (30%) of such shares, or (y) the first purchase of shares
                pursuant to a tender or exchange offer (other than one made
                by the Company) for voting shares of the Company or
                securities convertible into voting shares, after which offer
                the offeror, if successful, will become the beneficial owner
                of at least 30% of the outstanding voting shares of the
                Company.

     For purposes of this Section 18, the income tax liability incurred by

                                     - 9 -


<PAGE>   31

the Option holder shall be calculated as described in the attached appendix
A, as of the date on which an amount is includible in the Option holder's
income pursuant to Section 83 of the Internal Revenue Code of 1986 as a
consequence of his acquisition of stock pursuant to the exercise of an
Option.  The fair market value of the Option stock shall be its closing
price on the American Stock Exchange or other exchanges or markets where
such shares are permanently traded, for the date in question, and the tax
rate applicable to an Option holder shall be the single rate or the highest
graduated rate (exclusive of surtax) applied to earned income by a relevant
taxing jurisdiction.

19.  PERFORMANCE UNITS.  All Performance Units granted under the Plan shall
be on the following terms and conditions (and such other terms and
conditions that the Administrators may establish which are consistent with
the Plan):

     (a)  A Performance Unit is defined as the right of a key employee who
          has been granted the same to receive cash and/or Common Stock
          and/or Options conditioned upon and measured by the attainment of
          financial goals set by the Administrators.  Performance Units
          granted under the Plan shall be evidenced by agreements in such
          form and containing such terms and conditions, not inconsistent
          with the Plan, as the Administrators may approve.

     (b)  The Administrators shall determine the number of Performance Units
          to be granted to each key employee selected for an award and may
          establish a stated value (the "Stated Value") of each Performance
          Unit.

     (c)  Payment of Performance Units shall be made by the Company to the
          extent that such Performance Units are earned out by attainment of
          the performance objectives set for such Performance Units by the
          Administrators pursuant to subsection (d) below.  Such payment may
          be in the form of the grant of Options, or, if made in cash or
          shares of Common Stock, shall have a value equal to the dollar
          value of the Performance Units earned out.  Subject to the
          provisions of Section 5, payment of the amounts to which
          participants are entitled to be paid in respect of Performance
          Units as provided above shall be made in cash, shares of Common
          Stock or Options, or in some combination thereof, as the
          Administrators may determine.  The Administrators, in their sole
          discretion, may defer distribution of one-half of the amount of
          the payment for a period up to twelve months following the date in
          which the decision as to entitlement to payment is made.

     (d)  The award period ("Award Period") in respect of any Performance
          Units shall be a period set by the Administrators.  At the time
          each grant of Performance Units is made, the Administrators shall
          establish performance objectives to be attained within the Award
          Period as a condition of such Performance Units being earned out.
          The performance objectives shall be based on a specific dollar
          amount of growth or on a percentage rate of improvement in such
          elements as the Company's (or a subsidiary's) earnings per share,
          income, return on equity or such other measures related to growth


                                     - 10 -

<PAGE>   32
          or improvement of the Company (or its Subsidiaries) as the
          Administrators shall determine.  The Administrators shall
          determine whether the performance objectives in respect of an
          Award Period have been attained, as well as the value of the
          Performance Units consequently earned out.

     (e)  In the event that recipient of a grant of Performance Units ceases
          to be a key employee prior to the end of the Award Period by
          reason of disability or death, his Performance Units if ultimately
          earned out shall be payable at the end of the Award Period in
          proportion to the active service of the key employee during the
          Award Period, as determined by the Committee.  Upon any other
          termination of employment, Performance Units and all rights
          associated therewith shall terminate unless the Administrators in
          their discretion shall determine otherwise.  For purposes of this
          subsection, the term "disability" means disability as defined in
          any disability program maintained by the Company or a subsidiary.

     (f)  Performance Units may not be transferred otherwise than by will or
          the laws of descent.

     (g)  If, as a result of any change in accounting principles or
          practices or the method of their application or in any tax or
          other laws or regulations, the earnings per share or other
          established criteria of the Company or its Subsidiaries as
          reported in the Company's annual report to stockholders differs
          materially from the earnings per share or other such criteria
          which would have been reported absent such change, the
          Administrators may, in their discretion, equitably adjust the
          reported earnings per share or other such criteria used in
          determining the attainment of any performance objectives
          previously established by the Administrators as a condition of
          earning out Performance Units.

     (h)  In the event of a stock dividend or other transaction described in
          the last paragraph of Section 4, the Administrators may make
          appropriate adjustments in performance objectives, such as
          earnings per share, for outstanding Performance Units.  In the
          event of a merger, consolidation, acquisition or liquidation
          described in the Section 15, all outstanding Performance Units and
          all rights relating thereto shall terminate, except as otherwise
          determined by the Administrators.

     (i)  No payments will be made with respect to Performance Units unless
          arrangements satisfactory to the Administrators are made for any
          federal income tax withholding or other withholding required.

     (j)  Unless Shares deliverable upon earn out of Performance Units are
          registered or qualified for public sale by an effective
          Registration Statement of the Company under the Securities Act of
          1933, as amended (or any superseding law) and are registered or
          qualified for sale under all applicable state securities laws, the

          person to whom the Common Stock is delivered shall confirm to the
          Company that such recipient is purchasing the Shares for
          investment and not with a view to effecting any distribution or
          resale of the Shares.
