                                PROXY STATEMENT
 
                               ----------------
 
General Information
 
  This Proxy Statement is furnished to the holders of Common Stock, $.01 par
value per share ("Common Stock"), of Roberts Pharmaceutical Corporation (the
"Company") in connection with the solicitation of proxies by the Board of
Directors of the Company (the "Board of Directors") for use at the annual
meeting of shareholders to be held on May 27, 1999, and at any adjournment
thereof (the "Annual Meeting"). A form of proxy for use at the meeting is also
enclosed. The Company anticipates mailing this Proxy Statement and the
enclosed proxy card to its shareholders on or about April 30, 1999. The
executive offices of the Company are located at Meridian Center II, 4
Industrial Way West, Eatontown, New Jersey 07724.
 
  Shareholders may revoke the authority granted by their execution of proxies
at any time before the effective exercise of proxies by filing written notice
of such revocation with the Secretary of the Annual Meeting. Presence at the
Annual Meeting does not of itself revoke the proxy. All shares represented by
executed and unrevoked proxies will be voted in accordance with the
instructions therein. Proxies submitted without indication will be voted FOR
the nominees for Director named herein and FOR the proposal to amend the
Roberts Pharmaceutical Corporation 1996 Equity Incentive Plan (the "Equity
Incentive Plan") described herein. Management is not aware, at the date
hereof, of any matters to be presented at the Annual Meeting other than the
matters described hereinabove, but, if any other matter is properly presented,
the persons named in the proxy will vote thereon according to their best
judgment.
 
  The cost of preparing, assembling and mailing the proxy material is to be
borne by the Company. It is not anticipated that any compensation will be paid
for soliciting proxies, and the Company does not intend to employ specially
engaged personnel in the solicitation of proxies. It is contemplated that
proxies will be solicited principally through the mail. Further, Directors,
officers and employees of the Company may also, without additional
compensation, solicit proxies, personally or by mail, telephone, telegraph,
facsimile transmission or special letter.
 
Voting Securities
 
  The voting securities entitled to vote at the Annual Meeting consist of
shares of Common Stock of the Company with each share of Common Stock
entitling its owner to one vote on an equal basis. As of April 16, 1999, the
Company had 31,613,810 outstanding shares of Common Stock. Only shareholders
of record on the books of the Company at the close of business on that date
will be entitled to vote at the Annual Meeting. The holders of a majority of
the outstanding shares of Common Stock, present in person or by proxy and
entitled to vote, will constitute a quorum at the Annual Meeting for purposes
of electing Directors and acting upon the proposal to amend the Equity
Incentive Plan. Abstentions and broker non-votes will be counted for purposes
of determining whether a quorum is present at the Annual Meeting.
 
  Directors shall be elected by a plurality of the votes cast at the Annual
Meeting by the holders of shares of Common Stock present in person or
represented by proxy and entitled to vote. The proxy card provides space for a
shareholder to withhold votes for any or all nominees for the Board of
Directors. The proposal to amend the Equity Incentive Plan must be approved by
a majority of the votes cast at the Annual Meeting by the holders of shares of
Common Stock present in person or represented by proxy and entitled to vote.
 
  All votes will be tabulated by the inspector of election appointed for the
Annual Meeting who will separately tabulate affirmative votes, negative votes,
authority withheld for any nominee for Director, abstentions and broker non-
votes. Any proxy submitted and containing an abstention or a broker non-vote
with respect to any matter voted upon will not be counted as a vote cast on
such matter.

Agreements with Yamanouchi
 
  Yamanouchi, through a subsidiary, owns 5,048,500 shares of the Company's
Common Stock. Of such shares, 4,000,000 were acquired in March 1992 pursuant
to the terms of a stock purchase agreement (the "Stock Purchase Agreement")
entered into by the Company and Yamanouchi. Under the terms of the Stock
Purchase Agreement, Yamanouchi has certain preemptive rights to acquire
securities issued by the Company for so long as Yamanouchi owns at least 15%
of the Company's outstanding Common Stock on a fully diluted basis, and the
Company is prohibited from taking any action to prevent Yamanouchi from
directly or indirectly acquiring all of the remaining shares of the Company's
outstanding Common Stock, provided that any such acquisition is made in
accordance with the terms of the Stock Purchase Agreement. Yamanouchi is under
no obligation to acquire additional shares of Common Stock. For so long as
Yamanouchi owns 10% of the Company's outstanding Common Stock on a fully
diluted basis, Yamanouchi has granted the Company a right of first refusal
with respect to any shares of Common Stock which it proposes to sell, subject
to certain specified exceptions.
 
  The Company has granted Yamanouchi certain demand and piggyback registration
rights with respect to the shares of Common Stock owned by it. Under the Stock
Purchase Agreement, the Company is required to discuss with and obtain the
views of Yamanouchi with respect to certain specified transactions, including
equity offerings; incurring a material amount of debt; a material change in
the Company's capital structure; and the granting of any material license to a
third party. If any such proposed transaction involves a financing, the
Company has agreed to review with Yamanouchi its financing needs prior to
engaging in such transaction and to give Yamanouchi a reasonable opportunity
to propose and negotiate a financing alternative for the Company, though
Yamanouchi is under no obligation to do so.
 
  Yamanouchi is entitled to designate two members of the Company's Board of
Directors for so long as it owns at least 18% of the outstanding shares of the
Company's Common Stock on a fully diluted basis (or one Director for so long
as it owns at least 10% of the Company's Common Stock). As of April 16, 1999,
Yamanouchi owned more than 10% but less than 18% of the outstanding shares of
the Company's Common Stock on a fully diluted basis and is entitled to
designate one Director. Yamanouchi has not designated any nominee for election
to the Board of Directors at the Annual Meeting.
 
  Pursuant to a Shareholder Agreement between Yamanouchi and Dr. Vukovich (the
"Shareholder Agreement") entered into at the same time as the Stock Purchase
Agreement, Dr. Vukovich has granted Yamanouchi certain rights of first refusal
with respect to shares of the Company's outstanding Common Stock that he
proposes to sell, though Yamanouchi has no obligation to purchase any such
shares. Pursuant to the Shareholder Agreement, Dr. Vukovich has agreed to vote
all shares of Common Stock held by him in favor of the election of
Yamanouchi's Board of Directors designee(s), if any.
 
                             ELECTION OF DIRECTORS
                            (Item 1 on Proxy Card)
 
  In accordance with the Company's By-Laws which provide that the Board of
Directors shall consist of not less than three nor more than fifteen members,
the Board of Directors has fixed the number of Directors at nine. Each of the
individuals named below has been nominated for election as a Director by the
Board of Directors. With the exception of Ronald M. Nordmann, each such
individual named below is currently a member of the Board of Directors of the
Company.

  It is the intention of the persons named in the accompanying proxy to vote,
unless otherwise instructed, in favor of the election of the nine nominees
named below as Directors of the Company.
 
  THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE NOMINEES FOR DIRECTOR.
 
  If any of the nominees should be unavailable for election, the proxies will
be voted for the election of such other person or persons as shall be
determined by the persons named in the proxy in accordance with their
judgment. The Company is not aware of any reason why any of the nominees would
be unavailable for election, or if elected, would be unable to serve as a
Director.

Officers or persons nominated by the Company to become Directors.

Employment Agreements
 
  In August 1998, the Company entered into new employment agreements with each
of Mr. Spitznagel, Mr. Loy, Mr. Rogalin and Mr. Rascio, which provide for
minimum annual base salaries of $350,000, $240,000, $193,000 and $160,000,
respectively. The agreements entitle each such officer to participate in any
incentive compensation plan offered to the Company's senior level management
and to receive all vacation and other benefits, including insurance, provided
to employees of the Company.
 
  Under the terms of the employment agreements with Mr. Spitznagel, Mr. Loy
and Mr. Rascio, in the event that the employment of any such officer is
terminated by the Company other than for the officer's willful misconduct, the
officer is entitled to receive (i) base compensation, at the annual rate at
the time of termination, for three years (four years for Mr. Spitznagel) after
the termination, (ii) additional payments equal to three times (four times for
Mr. Spitznagel) the officer's average annual bonus and incentive compensation
(or $50,000 if the average bonus is less than $50,000) for the period
commencing March 4, 1996 for Mr. Spitznagel, August 31, 1992 for Mr. Loy and
July 1, 1988 for Mr. Rascio, and ending upon the termination of employment,
and (iii) an amount equal to three times (four times for Mr. Spitznagel) any
payment made by the Company to the 401(k) Plan on behalf of the officer during
the fiscal year prior to termination (all such payments made to an officer in
connection with the termination of employment are referred to herein
collectively as "Severance Compensation"). At the election of the officer, the
Severance Compensation shall be paid to the officer either in a lump sum or in
the same manner and on the same dates as the officer would have received such
compensation had the termination of employment not occurred.
 
  Under the terms of the employment agreements with Mr. Spitznagel, Mr. Loy
and Mr. Rascio, in the event that the employment of any such officer is
terminated by the Company in connection with a "change in control" of the
Company (as defined in each of their employment agreements), the officer is
entitled to receive the full amount of the Severance Compensation. Following a
change in control of the Company, each of Mr. Spitznagel, Mr. Loy and Mr.
Rascio have the right to terminate their employment agreements and receive the
full amount of the Severance Compensation, if he remains in the employ of the
Company or any successor thereto for a period of one (1) year following a
change in control and provides the Company with notice of termination during
the thirty (30) day period immediately following the end of such one (1) year
period, or at any time after the change in control if (i) his duties are
diminished, (ii) his place of employment is relocated more than twenty (20)
miles from its prior location, or (iii) his annual compensation is reduced.
 
                                      10
<PAGE>
 
  Under the terms of the employment agreement with Mr. Rogalin, in the event
that his employment is terminated by the Company in connection with a "change
in control" of the Company (as such term is defined in his employment
agreement), Mr. Rogalin is entitled to receive his base compensation as of the
date of his termination for a period of three (3) years following the
termination.
 
  The Internal Revenue Code of 1986, as amended (the "Code"), imposes an
excise tax on and limits the Company's deduction of payments to terminated
employees following a change in control if the payments meet certain
requirements and exceed the limit set forth in the Code. Generally, this limit
is equal to three times the employee's average annual compensation for the
five taxable years preceding the year in which the change of control occurs.
The employment agreements with Mr. Spitznagel, Mr. Loy, Mr. Rogalin and Mr.
Rascio provide that the Company shall pay any such excise taxes assessed
against the officers in connection with any Severance Compensation payments
made or benefits conferred under the employment agreements, including, in
connection with a change in control of the Company.
 
  In the event of the termination of an officer's employment with the Company
for any reason, each of these employment agreements provide that the officer
shall have the right to elect, during the one year period after the date of
termination, to exercise all options previously granted to the officer under
all stock option plans maintained by the Company, regardless of whether such
options would then be exercisable. In the event of the termination of the
employment agreement by an officer, each such agreement prohibits the officer
from engaging in any activities in direct competition with the Company for a
two year period. Under the terms of the employment agreements with Mr.
Spitznagel, Mr. Loy and Mr. Rascio, in the event of the "disability" of any
such officer (as defined in each of their employment agreements), he shall be
entitled to receive the full Severance Compensation from the Company. The
current terms of each of the employment agreements, which are automatically
renewed for successive one year periods upon their expiration, expire on
August 31, 2001, with the exception of Mr. Spitznagel's employment agreement
which expires on August 31, 2002.
 
Retirement of Dr. Vukovich
 
  In October 1998, Dr. Vukovich retired from active employment with the
Company, although he continues to serve as Chairman of the Board. In
connection with his retirement from the Company, the Board of Directors
approved a series of retirement benefits, including (i) a retirement bonus of
$250,000, (ii) an annual fee of $75,000 for as long as Dr. Vukovich serves as
Chairman of the Board; (iii) payment of all health insurance premiums for life
for both Dr. Vukovich and his wife; (iv) payment of all premiums on a $500,000
group term life insurance policy insuring Dr. Vukovich's life; (v) the
continued use of a Company car through the expiration of the car lease in
January 1999; (vi) accelerated vesting of all options and allowing Dr.
Vukovich to exercise such options on or before the original expiration dates;
and (vii) full vesting in his accrued benefit under the SERP. In addition, the

Employees Savings and Protection Plan
 
  The Company's 401(k) Plan is an employee savings plan available to all
employees who meet certain age and service requirements. In addition to salary
deferral contributions by the participating employees, the 401(k) Plan
provides for (i) mandatory contributions by the Company based on participant
contributions, and (ii) discretionary contributions by the Company based on a
percentage of a participant's compensation.
 
  For 1998, the total amount of employee and Company contributions under the
401(k) Plan will be $1,304,247 of which the Company will contribute $557,164.
See the Summary Compensation Table for amounts to be contributed by the
Company under the 401(k) Plan to the accounts of the Named Officers.

  The SERP is a funded, non-qualified defined benefit retirement plan which
was adopted by the Board of Directors in order to provide a higher, more
competitive level of retirement benefits to certain designated executive
employees of the Company. In 1998, the Company engaged an outside consultant
to undertake a competitive review and analysis of the retirement benefits made
available by the Company to its executive employees. The consultant's report
concluded that the retirement benefits offered by the Company to its executive
employees were not competitive in the Company's marketplace for executives. In
order to enhance the retirement benefits for the Company's executive
employees, the consultant recommended the adoption of the SERP. In approving
and adopting the SERP, the Board of Directors believes that the retirement
benefits provided under the SERP can (i) be a factor in retaining certain key
executives as well as a factor in attracting other highly experienced and
talented individuals to the Company, and (ii) allow for appropriate succession
planning within the executive ranks of the Company.
 
  Under the SERP, participating employees are entitled to receive a benefit
equal to 65% of their highest average annual compensation for any period of 36
consecutive months or three (3) calendar years during the participant's final
120 months of employment, less (i) 50% of the employee's social security
benefit, and (ii) an actuarial equivalent of the employee's account balance in
the 401(k) Plan accumulated from Company contributions. A participating
employee's accrued benefit is determined as an annual single life annuity. A
participating employee's interest in his or her accrued benefit under the SERP
is fully vested upon completion of three (3) years of service with the Company
and reaching the age of sixty (60); provided, that if the employee has been
credited with less than ten (10) years of service at the time his or her
employment terminates, the accrued benefit shall be prorated based on actual
time of service. Upon death or total disability, a participating employee's
interest in his or her accrued benefit will be fully vested regardless of age,
but the benefit shall be prorated for less than ten (10) years of service.
Upon a change in control of the Company (as defined in the SERP), a
participating employee will become immediately and fully vested in his or her
accrued benefit regardless of age at termination of employment or years of
service upon reaching age fifty (50).
 
  In connection with its funding obligation under the SERP, the Board has
established a rabbi trust into which the Company will deposit all of its
required funding contributions. During 1998, the Company's expense with
respect to the SERP was approximately $2.1 million, of which $65,000 was
deposited into the trust. The balance of the Company's 1998 SERP expense will
be funded in 1999.

  Each of the Named Officers and certain other executive employees have been
designated as participants in the SERP. At December 31, 1998, the Named
Officers had the following credited years of service under the SERP: Mr.
Spitznagel 3 years; Dr. Vukovich 10 years; Mr. Loy 7 years; Mr. Rogalin 3
years; Mr. Rascio 10 years.
 
Employee Stock Purchase Plan
 
  Under the Stock Purchase Plan, eligible employees may use salary deductions
to invest in the Company's Common Stock pursuant to a plan which is intended
to qualify as an "employee stock purchase plan" within the meaning of Section
423 of the Code. Each eligible employee who elects to participate in the Stock
Purchase Plan shall be able to designate from 1% to 10% of the eligible
employee's compensation to purchase shares of the Company's Common Stock. The
fair market value of the aggregate number of shares of Common Stock which an
eligible employee may acquire under the Stock Purchase Plan in a particular
plan year may not exceed $25,000.
 
  The Stock Purchase Plan is administered by the Compensation Committee.
500,000 shares of the Company's Common Stock have been reserved for issuance
under the Stock Purchase Plan. The Stock Purchase Plan shall terminate when
all shares of Common Stock reserved for issuance are issued, or at any other
time at the discretion of the Board of Directors. As of April 16, 1999, 20,062
shares of the Company's Common Stock have been issued and allocated to
participant accounts under the Stock Purchase Plan.
 
Equity Incentive Plan
 
  For a description of the material features of the Equity Incentive Plan, see
"Summary of Provisions of the Equity Incentive Plan" under "Amendment of
Equity Incentive Plan."
 
Incentive Stock Option Plan and Restricted Stock Option Plan
 
  The Incentive Stock Option Plan and Restricted Stock Option Plan were
previously terminated. However, options granted under the Incentive Stock
Option Plan and Restricted Stock Option Plan which were outstanding on the
date of the termination of each such plan will continue to be exercisable
pursuant to their respective terms. As of April 16, 1999, there were 415,375
such incentive stock options and 40,000 such restricted stock options still
outstanding.

(1)  Represent shares of Common Stock underlying options granted under the
     Equity Incentive Plan.
(2)  The potential realizable value does not represent actual value. The
     value, if any, a Named Officer may realize will depend upon the excess of
     the fair market value of the Common Stock over the exercise price on the
     date the option is exercised. There is no assurance the value realized by
     the Named Officer will be at or near the estimated value. The estimated
     values are based upon assumptions of 5% and 10% appreciation,
     respectively, in the fair market value of the Company's Common Stock from
     the date of grant of these options through the expiration dates of such
     options.
(3)  50% of these options are immediately exercisable and the remaining 50%
     become exercisable on the one year anniversary of the date of grant of
     the options.
(4)  Represents the immediately exercisable options granted in connection with
     the accelerated vesting of all outstanding SARs by the Company and the
     voluntary exercise of such SARs by the Named Officer. See "Option

     on Executive Compensation."
(5)  These options may be exercised in equal installments of 20% on the first,
     second, third, fourth and fifth year anniversaries of the date of grant
     of the options.

Option Exercises and Fiscal Year-End Values
 
  Shown below is information regarding options and SARs exercised by certain
of the Named Officers during 1998 as well as information regarding options
held by each of the Named Officers at December 31, 1998. During the year ended
December 31, 1998, 156,000 options and 502,500 SARs were exercised by certain
of the Named Officers. In order to mitigate the potential future compensation
expense which the Company would have to recognize with respect to the SARs, in
1998 (i) the Company accelerated the vesting of all outstanding SARs, and (ii)
the Executive Officers of the Company holding such SARs agreed to voluntarily
exercise all of their outstanding SARs. By exercising all of their SARs, the
Executive Officers forfeited the additional value which they potentially could
have realized during the term of their SARs if the price of the Company's
Common Stock were to increase over the Company's stock price on the dates on
which these SARs were exercised. In connection with the acceleration of
vesting and the exercise of all of their outstanding SARs, these Executive
Officers also received immediately exercisable options under the Equity
Incentive Plan to purchase one share of the Company's Common Stock for every
two (2) SARs exercised. At December 31, 1998 and at April 16, 1999, there were
no outstanding SARs.

     Spitznagel, Dr. Vukovich, Mr. Loy and Mr. Rogalin, respectively. No
     shares of Common Stock were received upon the exercise of the SARs,
     rather cash in the amounts set forth in footnote (2) below was received
     by each of these Named Officers.
(2)  Includes $407,813 and $577,875 as the value realized by Dr. Vukovich and
     Mr. Loy, respectively, with respect to the exercise of options. The value
     realized with respect to exercised options is the product of (i) the
     number of shares of Common Stock acquired upon exercise of the options
     and (ii) the difference between (a) the average sale price of the
     Company's Common Stock on the American Stock Exchange on the date of
     exercise of the options and (b) the exercise price of the options
     exercised. Includes also $708,000, $1,805,000, $447,750 and $351,000
     received in cash by Mr. Spitznagel, Dr. Vukovich, Mr. Loy and Mr.
     Rogalin, respectively, upon the exercise of their SARs.
(3)  The value of unexercised in-the-money options represents the difference
     between an option's exercise price and the reported last sale price of
     the Company's Common Stock on the American Stock Exchange on December 31,
     1998 ($21.50 per share). The actual value, if any, a Named Officer may
     realize upon the exercise of an option will depend upon the excess of the
     stock price over the exercise price on the date the option is exercised.
 
Executive Officer Loans
 
  In April 1999, the Board of Directors approved loans to be made by the
Company to Mr. Spitznagel and Mr. Rogalin in the amounts of $283,200 and
$144,400, respectively (the "Loans"). The Loans were approved to assist these
officers with their individual tax consequences relating to (i) the Company's
decision, in 1998, to accelerate the vesting of all outstanding SARs, and (ii)
the officers' decision to exercise voluntarily all of their
 
                                      15
<PAGE>
 
SARs, for the purpose of eliminating any potential future compensation expense
which the Company would be required to recognize with respect to the SARs. See
"Option Exercises and Fiscal Year-End Values" and "Compensation Committee
Report on Executive Compensation." The Loan amounts are approximately forty
percent (40%) of the amount of compensation income to be recognized by each
such officer in connection with the exercise of the officer's SARs. Each of
the Loans is unsecured, has a five (5) year term, and bears interest at the
rate of 4.15% per annum. Ten percent (10%) of the outstanding principal
balance of the Loan together with accrued interest is payable on each
anniversary of the Loan. The remaining principal amount of each Loan and all
accrued interest thereon is due and payable at the end of the term of the
Loan; provided, that all principal and interest owed with respect to such
officer's Loan shall be due and payable immediately upon the officer's
termination of employment.
 
Directors' Compensation
 
  Each Director who is not an employee of the Company is entitled to receive
an annual fee of $25,000 for services as a Director. Dr. Vukovich, for his
services as Chairman of the Board, is entitled to receive an annual fee of
$75,000. Each non-employee Director is entitled to receive a participation fee
of $2,000 for each meeting of the Board of Directors attended and a fee of
$500 for each meeting attended of any committee of the Board of Directors on
which such Director serves. In addition, each non-employee Director receives
annually options to purchase a minimum of 10,000 shares of the Company's
Common Stock. The Company paid a total of $196,689 during the year ended
December 31, 1998 to non-employee Directors. During the year ended December
31, 1998, a total of 87,500 options to purchase shares of Common Stock were
granted to the Company's non-employee Directors under the Equity Incentive
Plan. The Company makes no payment to Directors who are employees of the
Company for their services on the Board of Directors or committees thereof.
 
Compensation Committee Interlocks and Insider Participation
 
  During 1998, no member of the Compensation Committee was an employee of the
Company and no member of the Compensation Committee and no Executive Officer
named in this Proxy Statement has any relationship that must be disclosed
under this caption.
 
            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
General Compensation Policies
 
  The base salaries and wages for all the Company's employees are managed
through the Company's wage and salary administration program. Increases in
base salary and wages are managed according to three guidelines: individual
merit, promotions and competitive factors. Guidelines are established each
year and vary in order to reflect the Company's performance and the
competitive environment and to manage appropriately the overall cost of wage
and salary growth.
 
  The Company's compensation program is based on a pay for performance
criterion and consists of three key components: base salary, an annual
incentive bonus program and longer term incentives through the granting of
equity based awards, such as stock options. The compensation program is
designed to attract, retain and motivate the best personnel possible for all
levels of the Company. The Company's various programs are designed to treat
all employees in a fair and equitable manner and have the following common
attributes upon which compensation is based:
 
    . level of job responsibility;
    . individual performance;
    . company performance;
    . competitive marketplace factors.
 
Executive Officer Compensation
 
  The method of compensation of the Company's Executive Officers is consistent
with the Company's general compensation policies and is related to the
Company's growth and performance. The Compensation Committee is responsible
for administering the compensation program for Executive Officers of the
Company. The Compensation Committee believes that the Company's compensation
practices should reward strategic management of the business in the best long
term interests of the shareholders.
 
                                      16
<PAGE>
 
  A portion of an Executive Officer's compensation may consist of bonus
payments under the Management Incentive Compensation Plan. Under this plan,
awards are based on the Company's performance and the employee's contribution
to that performance. The aggregate amount allocated to any individual award
under the Management Incentive Compensation Plan is determined by the
Compensation Committee.
 
  The Company's long term incentives are generally in the form of stock option
grants. The objectives of the Company's stock option programs are to advance
the long term interests of the Company and its shareholders. Equity
compensation, in the form of stock options, is an important element of the
performance-based compensation of the Executive Officers. The grant of stock
options continues the Company's practice of providing for management's equity
ownership in order to ensure that their interests remain closely aligned with
those of the Company's shareholders. Equity ownership in the Company provides
a direct relationship between executive compensation and shareholder value.
Stock options provide the Company's key employees an opportunity for increased
equity ownership, and create an incentive to remain with the Company for the
long term.
 
  During the second quarter of 1998, the Compensation Committee recommended
and the Board of Directors approved the SERP, which is a non-qualified defined
benefit plan that provides retirement benefits to certain designated executive
employees of the Company. The Compensation Committee expects that the
increased retirement benefits will (i) be a factor in retaining certain key
executives as well as a factor in attracting other highly experienced and
talented individuals to the Company, and (ii) allow for appropriate succession
planning within the executive ranks of the Company. See "Supplemental
Executive Retirement Plan." The Compensation Committee believes that the
adoption of the SERP is fully consistent with the Company's compensation
philosophy and is a customary form of retirement benefit for executive
officers similar to that adopted by comparable companies. The 1998 SERP
expense to the Company was $2.1 million, of which $65,000 was funded by the
Company in 1998 with the balance to be funded in 1999.
 
  Also in 1998, in order to mitigate the potential future compensation expense
which the Company might have had to recognize with respect to outstanding
SARs, the Company accelerated the vesting of all such SARs and the Executive
Officers holding such SARs agreed to voluntarily exercise all such SARs
thereby terminating any potential benefit from the SARs which such Executive
Officers may have realized in the future. The exercise of all outstanding SARs
during 1998 resulted in a one time charge of $3.3 million, of which $0.7
million relates to the accelerated vesting and immediate exercise of the SARs.
In connection with the acceleration of vesting and the exercise of all
outstanding SARs, the Executive Officers who exercised the SARs received
immediately exercisable options to purchase one (1) share of the Company's
Common Stock for every two (2) SARs exercised by them. See "Option Exercises
and Fiscal Year-End Values."
 
  The compensation of the Company's Chief Executive Officer is determined by
the Compensation Committee based on its assessment of the Company's financial
and non-financial performance against a background of various factors. The
Compensation Committee has identified several factors which are critical to
the success of the business, including sales growth, business growth and
achievement, financial strength, progress toward achievement of goals and
growth in shareholder value. The Compensation Committee believes it is
important that these factors are well managed in order to maximize returns to
the Company's shareholders over the long term. Performance is reviewed on an
annual basis. In connection with his appointment as President and Chief
Executive Officer of the Company in 1997, Mr. Spitznagel signed a new
employment agreement in August 1998 replacing an agreement which was scheduled
to expire in September 2000. Under his new employment agreement, Mr.
Spitznagel received an increase in annual base salary from $300,000 to
$350,000. See "Employment Agreements."
 
  Incentive bonus awards to the Chief Executive Officer are determined by the
Compensation Committee based on the Company's performance and the Compensation
Committee's assessment of the individual contribution of the Chief Executive
Officer to that performance. The Compensation Committee awarded bonuses to the
Chief Executive Officer and other Executive Officers of the Company for 1998
as follows: Mr. Spitznagel--$450,000, Dr. Vukovich--$250,000, Mr. Loy--
$205,000, Mr. Rogalin--$125,000 and Mr. Rascio--
 
                                      17
<PAGE>
 
$60,000. In awarding these bonuses, the Compensation Committee focused on the
significant contribution of Mr. Spitznagel and the other Executive Officers of
the Company with respect to (i) the acquisition of the exclusive U.S. rights
to market PENTASA(R) from Hoechst Marion Roussel in April, 1998; (ii) the
divestiture of VRG International, Inc., the Company's contract research
business; (iii) entering into an agreement with RiboGene, Inc. whereby the
Company was granted the exclusive right to market EMITASOL(R) in the U.S.,
Canada, and Mexico; (iv) the sale of NORETHIN to, and the entering into a
Distribution Agreement for the distribution rights to SLOW-MAG(R) with, G.D.
Searle, (v) the settlement of a shareholders class action suit in January,
1998; (vi) the receipt of a patent for an improved process to manufacture
AGRYLIN(R) as well as receipt of Food and Drug Administration approval for the
use of AGRYLIN(R) in a broader patient population; and (vii) the improved
operating results of the Company.
 
  Options, including the options granted in connection with the acceleration
of vesting and exercise of the SARs, were granted in 1998 to Mr. Spitznagel
and the other Executive Officers of the Company as follows: Mr. Spitznagel--
202,500; Dr. Vukovich--262,500; Mr. Loy--108,750; Mr. Rogalin--50,500; and Mr.
Rascio--53,000. All options granted to Dr. Vukovich became fully vested in
connection with his retirement from the Company. See "Retirement of Dr.
Vukovich."
 
  Section 162(m) of the Code ("Section 162(m)"), disallows a tax deduction to
public companies for compensation over $1 million (per capita) paid to a
corporation's Chief Executive Officer and the four other highest paid
officers. Qualifying performance-based compensation is not subject to the
deduction limit if certain requirements are met. The Section 162(m) limitation
has not yet had any effect upon the Company and its ability to deduct, for tax
purposes, the compensation paid to the Company's Named Officers. Compensation
paid, or to be paid, pursuant to certain of the Company's employee benefit
plans will not qualify for the performance-based compensation exception to
Section 162(m) by reason of Dr. Vukovich's previous participation as a member
of the Compensation Committee. Dr. Vukovich resigned from the Compensation
Committee in 1995 with the intention that the Company would thus be able to
attempt to qualify compensation to be paid pursuant to future employee benefit
plans under the performance-based exception to Section 162(m).
 
  The Compensation Committee recognizes that certain future events, such as a
change in control of the Company, termination by the Company of certain
executive personnel, or the exercise of certain stock options, depending upon
the difference between the fair market value of the Company's Common Stock and
the exercise price of such an option on the date of exercise, may result in
the disallowance of a portion of the Company's compensation deductions under
Section 162(m) as it relates to the Named Officers of the Company. See
"Employment Agreements." Moreover, the Compensation Committee may from time to
time award compensation that may be non-deductible under Section 162(m) when,
in the exercise of the Compensation Committee's business judgment, such award
would be in the best interests of the Company.

         COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT
 
  Section 16(a) of the Exchange Act requires the Company's Executive Officers
and Directors, and persons who own more than ten percent of a registered class
of the Company's equity securities, to file reports of ownership and changes
in ownership on Forms 3, 4 and 5 with the Securities and Exchange Commission
("SEC"). Executive Officers, Directors and greater than ten percent
shareholders are required by SEC regulation to furnish the Company with copies
of all Forms 3, 4 and 5 they file.

  Based solely on the Company's review of the copies of such forms it has
received, the Company believes that all of its Executive Officers, Directors,
and greater than ten percent beneficial owners complied with all filing
requirements applicable to them with respect to reports required to be filed
by Section 16(a) of the Exchange Act during 1998.
 
                      AMENDMENT OF EQUITY INCENTIVE PLAN
                            (Item 2 on Proxy Card)
 
Introduction
 
  The Board of Directors has approved and adopted, subject to approval and
ratification by the shareholders, the following proposal to amend the Equity
Incentive Plan:
 
  TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK RESERVED FOR ISSUANCE UNDER
THE EQUITY INCENTIVE PLAN BY 1,500,000 SHARES TO 4,500,000 SHARES.
 
Summary of Provisions of the Equity Incentive Plan
 
  The Equity Incentive Plan was approved by the shareholders at the 1996
Annual Meeting. The Equity Incentive Plan is administered by the Compensation
Committee, which is authorized to grant (i) "incentive stock options" within
the meaning of Section 422 of the Code, (ii) nonqualified stock options, (iii)
stock appreciation rights, (iv) restricted stock grants, (v) deferred stock
awards, and (vi) other stock based awards to employees of the Company and its
subsidiaries and other persons and entities who, in the opinion of the
Compensation Committee, are in a position to make a significant contribution
to the success of the Company and its subsidiaries. The Compensation Committee
determines (i) the recipients of awards, (ii) the times at which awards will
be made, (iii) the size and type of awards, and (iv) the terms, conditions,
limitations and restrictions of awards. Awards may be made singly, in
combination or in tandem.
 
  When the Equity Incentive Plan was approved by the shareholders at the 1996
Annual Meeting, 1,500,000 shares of Common Stock were reserved for issuance.
In 1998, the Equity Incentive Plan was amended to increase the number of
shares of Common Stock reserved for issuance from 1,500,000 to 3,000,000, of
which 51,702 shares are not subject to awards which are currently outstanding.
The maximum number of shares of Common Stock which can be issued to the
Company's Chief Executive Officer under the Equity Incentive Plan pursuant to
various awards shall not exceed 35% of the total number of shares of Common
Stock reserved for issuance, and the maximum number of shares which can be
issued to any other employee or participant under the Equity Incentive Plan
shall not exceed 20% of the total number of shares of Common Stock reserved
for issuance. There are approximately 500 employees eligible to participate in
the Equity Incentive Plan and awards have been granted to approximately 479
employees. The Equity Incentive Plan will terminate on May 21, 2006, unless
earlier terminated by the Board of Directors.
 
Awards Under the Equity Incentive Plan
 
  Stock Options. The Compensation Committee can grant either incentive stock
options or nonqualified stock options. Only employees of the Company and its
subsidiaries may be granted incentive stock options. The exercise price of an
incentive stock option shall not be less than the fair market value, or, in
the case of an incentive stock option granted to a 10% or greater shareholder
of the Company, 110% of the fair market value of the Company's Common Stock on
the date of grant. For purposes of the exercise price of an option, "fair
market value" shall mean the arithmetic average of the highest and lowest sale
prices of the Common Stock reported on the American Stock Exchange on a
particular date. On April 16, 1999, the closing price of the Company's Common
Stock reported on the American Stock Exchange was $19.625 and the average of
the high and low sale prices was $19.75. The term of an option and the time or
times at which such option is exercisable
 
                                      19
<PAGE>
 
shall be set by the Compensation Committee; provided, however, that no option
shall be exercisable more than 10 years (5 years for an incentive stock option
granted to a 10% or greater shareholder of the Company) from the date of
grant, and with respect to an incentive stock option, the fair market value on
the date of grant of the shares of Common Stock which are exercisable by a
participant for the first time during any calendar year shall not exceed
$100,000. Payment of the exercise price shall be made in any form permitted by
the Compensation Committee, including cash and shares of the Company's Common
Stock.
 
  Stock Appreciation Rights. The Compensation Committee may grant stock
appreciation rights either alone or in combination with an underlying stock
option. The term of an SAR and the time or times at which an SAR shall be
exercisable shall be set by the Compensation Committee; provided, that an SAR
granted in tandem with an option will be exercisable only at such times and to
the extent that the related option is exercisable. SARs entitle the grantees
to receive an amount in cash or shares of Common Stock with a value equal to
the excess of the fair market value of a share of Common Stock on the date of
exercise over the fair market value of a share of Common Stock on the date the
SAR was granted, which represents the same economic value that would have been
derived from the exercise of an option. Payment may be made in cash, or shares
of Common Stock or a combination of both at the discretion of the Compensation
Committee. If a SAR granted in combination with an underlying stock option is
exercised, the right under the underlying option to purchase shares of Common
Stock is terminated.
 
  Restricted Stock Grants. The Compensation Committee may grant shares of
Common Stock under a restricted stock grant which sets forth the applicable
restrictions, conditions and forfeiture provisions which shall be determined
by the Compensation Committee and which can include restrictions on transfer,
continuous service with the Company or any of its subsidiaries, achievement of
business objectives, and individual, subsidiary and Company performance.
Shares of Common Stock may be granted pursuant to a restricted stock grant for
no consideration or for any consideration as determined by the Compensation
Committee. A grantee is entitled to vote the shares of Common Stock and
receive any dividends thereon prior to the termination of any applicable
restrictions, conditions or forfeiture provisions.
 
  Deferred Stock Awards. The Compensation Committee may grant shares of Common
Stock under a deferred stock award, with the delivery of such shares of Common
Stock to take place at such time or times and on such conditions as the
Compensation Committee may specify. Shares of Common Stock may be granted
pursuant to deferred stock awards for no consideration or for any
consideration as determined by the Compensation Committee.
 
  Other Stock Based Awards. The Compensation Committee may grant shares of
Common Stock to employees of the Company or its subsidiaries as bonus
compensation, or if agreed to by an employee, in lieu of such employee's cash
compensation.
 
Federal Income Tax Consequences
 
  Stock Options. The grant of an incentive stock option or a nonqualified
stock option does not result in income for the grantee or in a deduction for
the Company.
 
  The exercise of a nonqualified stock option results in ordinary income for
the grantee and a business deduction for the Company measured by the
difference between the option's exercise price and the fair market value of
the shares of Common Stock received at the time of exercise. If the Company is
required to withhold income taxes in connection with the exercise of a
nonqualified stock option, the Compensation Committee may, in its discretion,
permit such withholding obligation to be satisfied by the delivery of shares
of Common Stock held by the grantee or to be delivered to the grantee upon
exercise of the option.
 
  The exercise of a qualified incentive stock option does not result in income
for the grantee or in a business deduction for the Company; provided, that the
employee does not dispose of the shares of Common Stock
 
                                      20
<PAGE>
 
acquired upon exercise within two years after the date of grant of the option
and one year after the transfer of the shares of Common Stock upon exercise,
and provided that, the employee is employed by the Company or a subsidiary of
the Company from the date of grant until three months before the date of
exercise. If these requirements are met, the employee's basis in the shares of
Common Stock would be the exercise price. Any gain related to the subsequent
disposition of the shares of Common Stock will be taxed to the employee as a
long-term capital gain and the Company will not be entitled to any deduction.
The excess of the fair market value of the Common Stock on the date of
exercise over the exercise price is an item of tax preference for the
employee, potentially subject to the alternative minimum tax.
 
  If an employee should dispose of the shares of Common Stock acquired
pursuant to the exercise of an incentive stock option prior to the expiration
of either of the designated holding periods, the employee recognizes ordinary
income and the Company is entitled to a business deduction in an amount equal
to the lesser of the fair market value of the shares of Common Stock on the
date of exercise minus the option exercise price or the amount realized on
disposition of the shares of Common Stock minus the option exercise price. Any
gain in excess of the ordinary income recognized by the employee is taxable as
long-term or short-term capital gain, depending on the holding period. If an
option, intended to be an incentive stock option, does not satisfy all of the
requirements of an incentive stock option pursuant to Section 422 of the Code
when granted, the employee recognizes ordinary income upon exercise of the
option and the Company is entitled to a business deduction in an amount equal
to the fair market value of the shares of Common Stock on the exercise date
minus the option exercise price. Income tax withholding would be required. In
the event an option intended to be an incentive stock option does not qualify
as such when granted or when exercised, the Board of Directors believes that
any related deduction should not be subject to the annual $1 million per
capita limitation on employee remuneration for the Named Officers of the
Company imposed by Section 162(m) of the Code. The Board of Directors believes
that the income recognized by an employee or other participant upon the
exercise of an option granted under the Equity Incentive Plan should be
qualified performance-based compensation and, therefore, an exception to the
limitations imposed on the Company by Section 162(m) of the Code with respect
to the deductibility of a Named Officer's compensation during a particular
calendar year.
 
  SARS. The grant of an SAR does not result in income for the grantee or in a
business deduction for the Company for federal income tax purposes. Upon the
exercise of an SAR, the grantee recognizes ordinary income and the Company is
entitled to a business deduction measured by the fair market value of the
shares of Common Stock plus any cash received. Income tax withholding would be
required for employees of the Company and its subsidiaries. The Board of
Directors believes that any income related to the exercise of SARs should be
exempt from the $1 million limit of Section 162(m) of the Code pursuant to the
performance-based compensation exception.
 
  Restricted Stock Grants and Deferred Stock Awards. If the shares of Common
Stock issued pursuant to a restricted stock grant or deferred stock award are
subject to restrictions resulting in a "substantial risk of forfeiture"
pursuant to the meaning of such term under Section 83 of the Code, the
restricted stock grant or deferred stock award does not result in income for
the grantee or in a business deduction for the Company for federal income tax
purposes. If there are no such restrictions, conditions, limitations or
forfeiture provisions, the grantee recognizes ordinary income and the Company
is entitled to a business deduction upon receipt of the shares of Common
Stock. Dividends paid to the grantee while the stock remained subject to any
restrictions would be treated as compensation for federal income tax purposes.
At the time the restrictions lapse, the grantee receives ordinary income and
the Company is entitled to a business deduction, subject to the $1 million
deduction limitation under Section 162(m), measured by the fair market value
of the shares of Common Stock at the time of lapse. Income tax withholding
would be required for employees of the Company and its subsidiaries.
 
  Other Stock Based Awards. Any employee of the Company or any of its
subsidiaries who receives shares of Common Stock as bonus compensation or in
lieu of the employee's cash compensation shall recognize ordinary income, and
the Company shall be entitled to a business deduction, subject to the $1
million deduction limitation under Section 162(m), measured by the fair market
value of the shares of Common Stock issued to the employee.

Other Information
 
  If there is a stock split, stock dividend or other relevant change affecting
the Company's Common Stock, appropriate adjustments will be made in the number
of shares of Common Stock or in the type of securities to be issued pursuant
to any award granted before such event. In the event of a merger,
consolidation, combination or other similar transaction involving the Company
in which the Company is not the surviving entity, either all outstanding stock
options and SARs shall become exercisable immediately and all restricted stock
grants and deferred stock awards shall immediately become free of all
restrictions and conditions, or the Compensation Committee may arrange to have
the surviving entity grant replacement awards for all outstanding awards. Upon
termination of service prior to age 65 for any reason other than death or
disability, or upon involuntary termination after age 65, stock options and
SARs which are exercisable as of the date of such termination may be exercised
within three months of the date of termination, and any restricted stock
grants and deferred stock awards which are still subject to any restriction
shall be forfeited to the Company. Upon death or disability or voluntary
termination of service after age 65, all stock options and SARs become
immediately exercisable and may be exercised for a period of six months after
the date of termination (three months in the case of voluntary termination
after age 65), and all restricted stock grants and deferred stock awards shall
become immediately free of all restrictions and conditions. The Compensation
Committee has the discretionary authority to alter or establish the terms and
conditions of an award in connection with termination of service. The
employment agreements of Mr. Spitznagel, Mr. Loy, Mr. Rogalin and Mr. Rascio
provide that upon termination of their employment for any reason, they shall
have one (1) year to exercise all options which have been granted to them
under the Equity Incentive Plan. See "Employment Agreements." Shareholder
approval is required for the repricing of any option or other award. The Board
of Directors may amend, suspend or terminate the Equity Incentive Plan,
subject to shareholder approval if required pursuant to Section 162(m) of the
Code or the rules of the American Stock Exchange.

Vote Required
 
  Approval by the Company's shareholders of this proposal to amend the Equity
Incentive Plan to increase the number of shares of Common Stock reserved for
issuance by 1,500,000 shares requires the affirmative vote of a majority of
the votes cast at the Annual Meeting by the holders of shares of Common Stock
present in person or represented by proxy.
 
  The Board of Directors recommends a vote "FOR" the amendment to the
Company's Equity Incentive Plan to increase the number of shares reserved for
issuance thereunder by 1,500,000 from 3,000,000 shares to 4,500,000 shares.
 
                                 ANNUAL REPORT
 
  The annual report to shareholders for the fiscal year ended December 31,
1998 accompanies this Proxy Statement. Ernst & Young L.L.P. has audited the
financial statements for the fiscal year ended December 31, 1998, which
financial statements are contained in the annual report to shareholders. Such
annual report, including the audited financial statements contained therein,
is not incorporated in this Proxy Statement and is not deemed to be a part of
the proxy soliciting material.
 
                   RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS
 
  Selection of the independent public accountants for the Company is made by
the Board of Directors and is based upon the recommendation of the Company's
Audit Committee. On December 2, the Company received notice that
PricewaterhouseCoopers L.L.P. had resigned as the Company's independent public
accountants. The reports of PricewaterhouseCoopers L.L.P. on the financial
statements for the years ended December 31, 1997 and December 31, 1996
contained no adverse opinion or disclaimer of opinion and were not qualified
or modified as to uncertainty, audit scope or accounting principle. During the
years ended December 31, 1997 and December 31, 1996 and the period January 1,
1998 through November 25, 1998, there were no disagreements between the
Company and PricewaterhouseCoopers L.L.P. on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure, which disagreements if not resolved to the satisfaction of
PricewaterhouseCoopers L.L.P. would have caused it to make reference thereto
in connection with its reports on the financial statements. Further, there
have been no events involving the Company during the two (2) most recent
fiscal years and through November 25, 1998 which would require disclosure to
the SEC under Regulation S-K Item 304(a)(1)(v).
 
  Upon the recommendation of the Audit Committee, the Board of Directors
approved the engagement of Ernst & Young L.L.P. as the Company's new
independent public accountants on December 9, 1998. During the years ended
December 31, 1997 and December 31, 1996 and the period January 1, 1998 through
December 9, 1998, the Company had not consulted with Ernst & Young L.L.P.
regarding either (i) the application of accounting principles to any
transaction or audit opinion that might be rendered on the Company's financial
statements; or (ii) any matter that was either the subject of (a) a
disagreement between the Company and PricewaterhouseCoopers L.L.P., or (b) a
reportable event regarding internal controls of the Company, financial
statements prepared by the Company, expansion of the scope of the Company's
audit, or any other information deemed reportable.
 
  A representative of Ernst & Young L.L.P. will be present at the meeting and
will have an opportunity to make a statement if the representative desires to
do so. Said representative will also be available to respond to appropriate
questions from shareholders of the Company. The Company has appointed Ernst &
Young, L.L.P. as its independent public accountants for the year ending
December 31, 1999.

                       ROBERTS PHARMACEUTICAL CORPORATION
                     1996 EQUITY INCENTIVE PLAN, AS AMENDED



1.   PURPOSE.
     --------

     The purpose of this Roberts Pharmaceutical Corporation 1996 Equity
     Incentive Plan (the "Plan") is to advance the interests of Roberts
     Pharmaceutical Corporation (the "Company") and its subsidiaries by
     enhancing the ability of the Company to (i) attract and retain employees
     and other persons or entities who are in a position to make significant
     contributions to the success of the Company and its subsidiaries; (ii)
     reward such persons for such contributions; and (iii) encourage such
     persons or entities to take into account the long-term interest of the
     Company through ownership of shares of the Company's common stock, $.01 par
     value per share (the "Common Stock").

     The Plan is intended to accomplish these objectives by enabling the Company
     to grant awards ("Awards") in the form of incentive stock options ("ISOs"),
     nonqualified stock options ("Nonqualified Options") (ISOs and Nonqualified
     Options shall be collectively referred to herein as "Options"), stock
     appreciation rights ("SARs"), restricted stock ("Restricted Stock"),
     deferred stock ("Deferred Stock"), or other stock based awards ("Other
     Stock Based Awards"), all as more fully described below.

2.   ADMINISTRATION.
     ---------------

     The Plan will be administered by the Compensation Committee (the
     "Committee") of the Board of Directors of the Company (the "Board").  The
     Committee may be constituted to permit the Plan to comply with the
     "disinterested administration" requirement of Rule 16b-3(c)(2)(i)
     promulgated under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or any successor rules, and to comply with the "outside
     director" requirement of Section 162(m)(4)(c)(i) of the Internal Revenue
     Code of 1986, as amended (the "Code"), 
<PAGE>
 
     and the regulations promulgated thereunder, or any successor rules. The
     Committee will determine the recipients of Awards, the times at which
     Awards will be made, the size and type or types of Awards to be made to
     each recipient, and will set forth in each such Award the terms, conditions
     and limitations applicable to the Award granted. Awards may be made singly,
     in combination or in tandem. The Committee will have full and exclusive
     power to interpret the Plan, to adopt rules, regulations and guidelines
     relating to the Plan, to grant waivers of Plan restrictions and to make all
     of the determinations necessary for its administration. Such determinations
     and actions of the Committee, and all other determinations and actions of
     the Committee made or taken under authority granted by any provision of the
     Plan, will be conclusive and binding on all parties.

3.   EFFECTIVE DATE AND TERM OF PLAN.
     --------------------------------

     The Plan will become effective on May 22, 1996. Awards under the Plan may
     be made prior to that date, subject to the shareholders' approval of the
     Plan.

     The Plan will terminate on May 21, 2006, subject to earlier termination of
     the Plan by the Board pursuant to Section 18 herein.  No Award may be
     granted under the Plan after the termination date of the Plan, but Awards
     previously granted may extend beyond that date pursuant to the terms of
     such Awards.

4.   SHARES SUBJECT TO THE PLAN.
     ---------------------------

     Subject to adjustment as provided in Section 16 herein, the aggregate
     number of shares of Common Stock reserved for issuance pursuant to Awards
     granted under the Plan shall be 4,500,000.  The maximum number of shares of
     Common Stock which may be issued to the Chief Executive Officer ("CEO") of
     the Company pursuant to all Awards granted the CEO under the Plan shall not
     exceed thirty-five percent (35%) of the number of shares of the Company's
     Common Stock reserved for issuance hereunder.  The maximum number of shares
     of the Company's Common Stock awarded to any other "Participant" (as
     defined in Section 5 below) pursuant to all Awards granted to such
     Participant under the Plan shall not exceed twenty percent (20%) of the
     number of shares of the Company's Common Stock reserved for issuance
     hereunder.

                                      -2-
<PAGE>
 
     The shares of Common Stock delivered under the Plan may be either
     authorized but unissued shares of Common Stock or shares of the Company's
     Common Stock held by the Company as treasury shares, including shares of
     Common Stock acquired by the Company in open market and private
     transactions.  No fractional shares of Common Stock will be delivered
     pursuant to Awards granted under the Plan and the Committee shall determine
     the manner in which fractional share value will be treated.

     If any Award requiring exercise by a Participant for delivery of shares of
     Common Stock is cancelled or terminates without having been exercised in
     full, or if any Award payable in shares of Common Stock or cash is
     satisfied in cash rather than Common Stock, the number of shares of Common
     Stock as to which such Award was not exercised or for which cash was
     substituted will be available for future Awards of Common Stock; provided,
     however, that Common Stock subject to an Option cancelled upon the exercise
     of an SAR shall not again be available for Awards under the Plan unless,
     and to the extent that, the SAR is settled in cash. Shares of Restricted
     Stock and Deferred Stock forfeited to the Company in accordance with the
     Plan and the terms of the particular Award shall be available again for
     Awards under the Plan unless the Committee determines otherwise.

5.   ELIGIBILITY AND PARTICIPATION.
     ------------------------------

     Those eligible to receive Awards under the Plan (each, a "Participant" and
     collectively, the "Participants") will be persons in the employ of the
     Company or any of its subsidiaries designated by the Committee
     ("Employees") and other persons or entities who, in the opinion of the
     Committee, are in a position to make a significant contribution to the
     success of the Company or its subsidiaries, including, without limitation,
     consultants and agents of the Company or any subsidiary; provided, that
     such consultants and agents have been actively engaged in the conduct of
     the business of the Company or any subsidiary.  A "subsidiary" for purposes
     of the Plan will be a present or future corporation of which the Company
     owns or controls, or will own or control, more than 50% of the total
     combined voting power of all classes of stock or other equity interests.

                                      -3-

6.   OPTIONS.
     --------

     (a)  Nature of Options.  An Option is an Award entitling the Participant to
          ------------------                                                    
          purchase a specified number of shares of Common Stock at a specified
          exercise price.  Both ISOs, as defined in Section 422 of the Code, and
          Nonqualified Options may be granted under the Plan; provided however,
          that ISOs may be awarded only to Employees.

     (b)  Exercise Price.  The exercise price of each Option shall be equal to
          ---------------                                                     
          the "Fair Market Value" (as defined below) of the Common Stock on the
          date the Award is granted to the Participant; provided, however, that
          (i) in the Committee's discretion, the exercise price of a
          Nonqualified Option may be less than the Fair Market Value of the
          Common Stock on the date of grant; (ii) with respect to a Participant
          who owns more than ten percent (10%) of the total combined voting
          power of all classes of stock of the Company, the option price of an
          ISO granted to such Participant shall not be less than one hundred and
          ten percent (110%) of the Fair Market Value of the Common Stock on the
          date the Award is granted; and (iii) with respect to any Option
          repriced by the Committee, the exercise price shall be equal to the
          Fair Market Value of the Common Stock on the date such Option is
          repriced unless otherwise determined by the Committee.  For purposes
          of this Plan, Fair Market Value shall mean the arithmetic average of
          the highest and lowest sale prices of the Common Stock as reported on
          the Automated Quotation System of the National Association of
          Securities Dealers, Inc. National Market System ("NASDAQ National
          Market System"), on a particular date, or if there is no sale on such
          date, then the average of such high and low sale prices on the last
          previous date on which a sale of Common Stock is reported on the
          NASDAQ National Market System.

     (c)  Duration of Options.  The term of each Option granted to a Participant
          --------------------                                                  
          pursuant to an Award shall be determined by the Committee; provided,
          however, that in no case shall an Option be exercisable more than ten
          (10) years (five (5) years in the case of an ISO granted to a ten-
          percent shareholder as defined in (b) above) from the date of the
          Award.

                                      -4-
<PAGE>
 
     (d)  Exercise of Options and Conditions.  Except as otherwise provided in
          -----------------------------------                                 
          Sections 16 and 17 herein, and except as otherwise provided below with
          respect to ISOs, Options granted pursuant to an Award will become
          exercisable at such time or times, and on and subject to such
          conditions, as the Committee may specify at the time of the Award.
          The Options may be subject to such restrictions, conditions and
          forfeiture provisions as the Committee may determine, including, but
          not limited to, restrictions on transfer, continuous service with the
          Company or any of its subsidiaries, achievement of business
          objectives, and individual, division and Company performance.  To the
          extent exercisable, an Option may be exercised either in whole at any
          time or in part from time to time.  With respect to an ISO granted to
          a Participant, the Fair Market Value of the shares of Common Stock on
          the date of grant which are exercisable for the first time by a
          Participant during any calendar year shall not exceed $100,000.

     (e)  Payment for and Delivery of Stock.  Full payment for shares of Common
          ----------------------------------                                   
          Stock purchased will be made at the time of the exercise of the
          Option, in whole or in part.  Payment of the purchase price will be
          made in cash or in such other form as the Committee may permit,
          including, without limitation, delivery of shares of Common Stock.

7.   STOCK APPRECIATION RIGHTS.
     --------------------------

     (a)  Nature of Stock Appreciation Rights.  A SAR is an Award entitling the
          ------------------------------------                                 
          recipient to receive payment, in cash and/or shares of Common Stock,
          determined in whole or in part by reference to appreciation in the
          value of a share of Common Stock.  A SAR entitles the recipient to
          receive in cash and/or shares of Common Stock, with respect to each
          SAR exercised, the excess of the Fair Market Value of a share of
          Common Stock on the date of exercise over the Fair Market Value of a
          share of Common Stock on the date the SAR was granted.

     (b)  Grant of SARs.  SARs may be subject to Awards in tandem with, or
          --------------                                                  
          independently of, Options granted under the Plan.  A SAR granted in
          tandem with an Option which is not an ISO may be granted either at or
          after the time 

                                      -5-
<PAGE>
 
          the Option is granted. A SAR granted in tandem with an ISO may be
          granted only at the time the ISO is granted and may expire no later
          than the expiration of the underlying ISO.

     (c)  Exercise of SARs.  A SAR not granted in tandem with an Option will
          -----------------                                                 
          become exercisable at such time or times, and on such conditions, as
          the Committee may specify. A SAR granted in tandem with an Option will
          be exercisable only at such times, and to the extent, that the related
          Option is exercisable.  A SAR granted in tandem with an ISO may be
          exercised only when the market price of the shares of Common Stock
          subject to the ISO exceeds the exercise price of the ISO, and the SAR
          may be for no more than one hundred percent (100%) of the difference
          between the exercise price of the underlying ISO and the Fair Market
          Value of the Common Stock subject to the underlying ISO at the time
          the SAR is exercised.  At the option of the Committee, upon exercise,
          an SAR may be settled in cash, Common Stock or a combination of both.

8.   RESTRICTED STOCK.
     -----------------

     A Restricted Stock Award entitles the recipient to acquire shares of Common
     Stock, subject to certain restrictions or conditions, for no cash
     consideration, if permitted by applicable law, or for such other
     consideration as may be determined by the Committee.  The Award may be
     subject to such restrictions, conditions and forfeiture provisions as the
     Committee may determine, including, but not limited to, restrictions on
     transfer, continuous service with the Company or any of its subsidiaries,
     achievement of business objectives, and individual, division and Company
     performance.  Subject to such restrictions, conditions and forfeiture
     provisions as may be established by the Committee, any Participant
     receiving an Award of Restricted Stock will have all the rights of a
     shareholder of the Company with respect to the shares of Restricted Stock,
     including the right to vote the shares and the right to receive any
     dividends thereon.

 9.  DEFERRED STOCK.
     ---------------

                                      -6-
<PAGE>
 
     A Deferred Stock Award entitles the recipient to receive shares of Common
     Stock to be delivered in the future. Delivery of the shares of Common Stock
     will take place at such time or times, and on such conditions, as the
     Committee may specify.  At the time any Deferred Stock Award is granted,
     the Committee may provide that the Participant will receive an instrument
     evidencing the Participant's right to future delivery of Deferred Stock.

10.  OTHER STOCK BASED AWARDS.
     -------------------------

     The Committee shall have the right to grant Other Stock Based Awards under
     the Plan to Employees which may include, without limitation, the grant of
     shares of Common Stock as bonus compensation and the issuance of shares of
     Common Stock in lieu of an Employee's cash compensation.

11.  AWARD AGREEMENTS.
     -----------------

     The grant of any Award under the Plan may be evidenced by an agreement
     which shall describe the specific Award granted and the terms and
     conditions of the Award.  Any Award shall be subject to the terms and
     conditions of any such agreement required by the Committee.

12.  TRANSFERS.
     ----------

     No Award (other than an outright Award in the form of Common Stock without
     any restrictions) may be assigned, pledged or transferred other than by
     will or by the laws of descent and distribution and, during a Participant's
     lifetime, will be exercisable only by the Participant or, in the event of a
     Participant's incapacity, by the Participant's guardian or legal
     representative.

13.  RIGHTS OF A SHAREHOLDER.
     ------------------------

     Except as specifically provided by the Plan, the receipt of an Award will
     not give a Participant rights as a shareholder of the Company.  The
     Participant will obtain such rights, subject to any limitations imposed by
     the Plan, or the instrument evidencing the Award, upon actual receipt of
     shares of Common Stock.

14.  CONDITIONS ON DELIVERY OF STOCK.
     --------------------------------

                                      -7-
<PAGE>
 
     The Company will not be obligated to deliver any shares of Common Stock
     pursuant to the Plan or to remove any restrictions or legends from shares
     of Common Stock previously delivered under the Plan until, (a) in the
     opinion of the Company's counsel, all applicable federal and state laws and
     regulations have been complied with,

     (b) until the shares of Common Stock to be delivered have been listed or
     authorized to be listed on the NASDAQ National Market System, and (c) until
     all other legal matters in connection with the issuance and delivery of
     such shares of Common Stock have been approved by the Company's counsel.
     If the sale of shares of Common Stock has not been registered under the
     Securities Act of 1933, as amended (the "Act"), and qualified under the
     appropriate "blue sky" laws, the Company may require, as a condition to
     exercise of the Award, such representations and agreements as counsel for
     the Company may consider appropriate to avoid violation of such Act and
     laws and may require that the certificates evidencing such shares of Common
     Stock bear an appropriate legend restricting transfer.

     If an Award is exercised by a Participant's legal representative, the
     Company will be under no obligation to deliver shares of Common Stock
     pursuant to such exercise until the Company is satisfied as to the
     authority of such representative.

15.  TAX WITHHOLDING.
     ----------------

     The Company will have the right to deduct from any cash payment under the
     Plan taxes that are required to be withheld and to condition the obligation
     to deliver or vest shares of Common Stock under this Plan upon the
     Participant's paying the Company such amount as the Company may request to
     satisfy any liability for applicable withholding taxes.  The Committee may
     in its discretion permit Participants to satisfy all or part of their
     withholding liability either by delivery of shares of Common Stock held by
     the Participant or by withholding shares of Common Stock to be delivered to
     a Participant upon the grant or exercise of an Award.

16.  ADJUSTMENT OF AWARD.
     --------------------

                                      -8-
<PAGE>
 
     (a)  In the event that a dividend shall be declared upon the Common Stock
          payable in shares of Common Stock, the number of shares of the Common
          Stock then subject to any Award and the number of shares of the Common
          Stock which may be issued under the Plan but not yet covered by an
          Award shall be adjusted by adding to each share the number of shares
          which would be distributable thereon if such shares had been
          outstanding on the date fixed for determining the shareholders
          entitled to receive such stock dividend.  In the event that the
          outstanding shares of the Common Stock shall be changed into or
          exchanged for a different number or kind of shares of Common Stock or
          other securities of the Company or of another corporation or for cash,
          whether through reorganization, recapitalization, stock split,
          combination of shares, sale of assets, merger or consolidation in
          which the Company is the surviving corporation, then, there shall be
          substituted for each share of the Common Stock then subject to any
          Award, the number and kind of shares of stock or other securities or
          the amount of cash into which each outstanding share of the Common
          Stock shall be so changed or for which each such share shall be
          exchanged.

     (b)  In the event of a proposal, which is approved by the Board, of any
          merger or consolidation involving the Company where the Company is not
          the surviving entity, any sale of substantially all of the Company's
          assets or any other transaction or series of related transactions as a
          result of which a single person or several persons acting in concert
          own a majority of the Company's then outstanding Common Stock (such
          merger, consolidation, sale of assets, or other transaction being
          hereinafter referred to as a "Transaction"), all outstanding Options
          and SARs shall become exercisable immediately before or
          contemporaneously with the consummation of such Transaction and each
          outstanding share of Restricted Stock and each outstanding Deferred
          Stock Award shall immediately become free of all restrictions and
          conditions upon consummation of such Transaction.  Upon consummation
          of the Transaction, all outstanding Options and SARs shall terminate
          and cease to be exercisable.

          In lieu of the foregoing, if the Company will not be the surviving
          corporation or entity, the Committee may arrange to have such
          acquiring or surviving corporation or entity, or an "Affiliate" (as
          defined below) thereof, grant replacement Awards to Participants
          holding outstanding Awards.

          The term "Affiliate," with respect to any Person, shall mean any other
          Person who is, or would be deemed to be an "affiliate" or an
          "associate" of such Person within the respective meanings ascribed to
          such terms in Rule 12b-2 of the General Rules and Regulations under
          the Exchange Act.  The term "Person" shall mean a corporation,
          association, partnership, joint venture, trust, organization,
          business, individual or government or any governmental agency or
          political subdivision thereof.

     (c)  In the event of the dissolution or liquidation of the Company (except
          a dissolution or liquidation relating to a sale of assets or other
          reorganization of the Company referred to in the preceding sections),
          the outstanding Options and SARs shall terminate as of a date fixed by
          the Committee; provided, however, that not less than thirty (30) days
          written notice of the date so fixed shall be given to each Participant
          who shall have the right during such period to exercise the
          Participant's Options or SARs as to all or any part of the shares of
          Common Stock covered thereby.  Further, in the event of the
          dissolution or liquidation of the Company, each outstanding share of
          Restricted Stock and each outstanding Deferred Stock Award shall
          immediately become free of all restrictions and conditions.

17.  TERMINATION OF SERVICE.
     -----------------------

     Upon a Participant's termination of service with the Company or a
subsidiary (if an employee only of a subsidiary), any outstanding Award shall be
subject to the terms and conditions set forth below, unless otherwise determined
by the Committee:

     (a)  In the event a Participant leaves the employ or service of the Company
          or, if the Participant is an employee only of a subsidiary of the
          Company, a subsidiary prior to the Participant's 65th birthday,
          whether voluntarily 

                                      -10-
<PAGE>
 
          or otherwise but other than by reason of the Participant's death or
          "disability" (as such term is defined in Section 22(e)(3) of the
          Code), each Option and SAR granted to the Participant shall terminate
          upon the earlier to occur of (i) the expiration of the period three
          (3) months after the date of such termination and (ii) the date
          specified in the Option or SAR; provided, that, prior to the
          termination of such Option or SAR, the Participant shall be able to
          exercise any part of the Option or SAR which is exercisable as of the
          date of termination. Further, each outstanding share of Restricted
          Stock and each outstanding Deferred Stock Award which remains subject
          to any restrictions or conditions of the Award shall be forfeited to
          the Company upon such date of termination.

     (b)  In the event a Participant's employment with or service to the Company
          or its subsidiaries terminates by reason of the Participant's death or
          "disability" (as such term is defined in Section 22(e)(3) of the
          Code), each Option and SAR granted to the Participant shall become
          immediately exercisable in full and shall terminate upon the earlier
          to occur of (i) the expiration of the period six (6) months after the
          date of such termination and (ii) the date specified in the Option or
          SAR.  Further, each outstanding share of Restricted Stock and each
          outstanding Deferred Stock Award shall immediately become free of all
          restrictions and conditions upon the date of such termination.

     (c)  In the event a Participant voluntarily leaves the employ or service of
          the Company or, if the Participant is an employee only of a subsidiary
          of the Company, a subsidiary after the Participant's 65th birthday,
          each Option and SAR granted to the Participant shall become
          immediately exercisable in full and shall terminate upon the earlier
          to occur of (i) the expiration of three (3) months after the date of
          such termination and (ii) the date specified in the Option or SAR.
          Further, each outstanding share of Restricted Stock and each
          outstanding Deferred Stock Award shall immediately become free of all
          restrictions and conditions upon the date of such termination unless
          otherwise provided in the Award.  If the Participant involuntarily
          leaves the employ or service of the Company or a subsidiary after 

                                      -11-
<PAGE>
 
          the Participant's 65th birthday, each Option and SAR granted to the
          Participant shall terminate upon the earlier to occur of (i) the
          expiration of three (3) months after the date of such termination and
          (ii) the date specified in the Option or SAR; provided, that, prior to
          the termination of such Option or SAR, the Participant shall be able
          to exercise any part of the Option or SAR which is exercisable as of
          the date of termination. Further, each outstanding share of Restricted
          Stock and each outstanding Deferred Stock Award which remains subject
          to any restrictions or conditions of the Award shall be forfeited to
          the Company upon such date of termination.

18.  AMENDMENTS AND TERMINATION.
     ---------------------------

     The Committee will have the authority to make such amendments to any terms
     and conditions applicable to outstanding Awards as are consistent with this
     Plan; provided, that, (i) except for adjustments under Section 16 hereof,
     no such action will modify such Award in a manner adverse to the
     Participant without the Participant's consent except as such modification
     is provided for or contemplated in the terms of the Award, and (ii) except
     for adjustments provided for in Section 16 of this Plan, the exercise price
     of any Option or SAR, or the consideration due the Company with respect to
     any other Award, shall not be repriced or otherwise amended without the
     approval of a majority of the votes cast by the Company's shareholders.

     The Board may amend, suspend or terminate the Plan, except (i) no such
     action may be taken, without shareholder approval, which would effectuate
     any change for which shareholder approval is required pursuant to Section
     16 of the Exchange Act or Section 162(m) of the Code, and (ii) no action
     may, without the consent of a Participant, alter or impair any Award
     previously granted to the Participant under the Plan.

19.  SUCCESSORS AND ASSIGNS.
     -----------------------

     The provisions of this Plan shall be binding upon all successors and
     assigns of any such Participant including, without limitation, the estate
     of any such Participant and the executors, administrators, or trustees of
     such estate, 

                                      -12-
<PAGE>
 
     and any receiver, trustee in bankruptcy or representative of the creditors
     of any such Participant.

20.  MISCELLANEOUS.
     ------------- 

     (a)  This Plan shall be governed by and construed in accordance with the
          laws of the State of New Jersey.

     (b)  Any and all funds received by the Company under the Plan may be used
          for any corporate purpose.

     (c)  Nothing contained in the Plan or any Award granted under the Plan
          shall confer upon a Participant any right to be continued in the
          employment of the Company or any subsidiary, or interfere in any way
          with the right of the Company, or its subsidiaries, to terminate the
          employment relationship at any time.
