                                 JUNE 23, 1998


     The accompanying proxy is solicited by and on behalf of the Board of
Directors of American Disposal Services, Inc., a Delaware corporation (the
"Company"), to be used at the Annual Meeting of Stockholders to be held at the
offices of the Company, 745 McClintock Drive, Suite 230, Burr Ridge, Illinois

     When the accompanying proxy is properly executed and returned, the shares

Option Plan as more fully described in Proposal 2 of this Proxy Statement; (iii)
FOR the ratification of the appointment of Ernst & Young LLP as the independent
auditors of the Company for the current fiscal year; and (iv) in the discretion
of the holders of the proxy with respect to any other business that may properly
come before the meeting and at any adjournments thereof.  Any stockholder
signing and delivering a proxy may revoke it at any time before it is voted by

Any stockholder attending the meeting in person may withdraw his proxy and vote

     A copy of the Notice of Annual Meeting of Stockholders accompanies this
Proxy Statement.  The approximate date on which this Proxy Statement first will
be mailed to stockholders of the Company is May 22, 1998.


                                 VOTING RIGHTS

     Only holders of record of shares of Common Stock at the close of business
on May 21, 1998 will be entitled to notice of and to vote at the Annual Meeting
of Stockholders.  On that date, the Company had outstanding 22,858,403 shares of
Common Stock, the holders of which are entitled to one vote per share on each
matter to come before the Annual Meeting.  Voting rights are non-cumulative.

     The presence, in person or by proxy, of stockholders holding a majority of
the outstanding shares of Common Stock will constitute a quorum at the Annual
Meeting.  Directors will be elected at the Annual Meeting by a plurality of the
votes cast.  For each other item to be acted upon at the Annual Meeting, the
affirmative vote of a majority of the votes cast will be required for approval.
Abstentions and broker non-votes (which occur when a nominee holding shares for
a beneficial owner does not vote on a particular proposal because the nominee
does not have discretionary voting power with respect to that item and has not
received instructions from the beneficial owner) are counted for purposes of
determining the presence or absence of a quorum at the meeting.  Abstentions are
counted in tabulations of the votes cast on proposals presented to stockholders,
but broker non-votes are not counted for purposes of determining whether a
proposal has been approved.


                                 SECURITY OWNERSHIP

     The following table sets forth certain information with respect to
beneficial ownership of the Common Stock as of May 1, 1998 by: (i) each person
known by the Company to be the beneficial owner of more than 5% of the Common
Stock; (ii) each of the Company's directors and nominees for directors; (iii)
the Company's Chief Executive Officer and each of the Company's other current
executive officers; and (iv) the Company's directors and executive officers as a
group.

(1) Amounts reported in these columns represent amounts that may be realized
upon exercise of options immediately prior to the expiration of their term
assuming the specified compounded rates of appreciation (5% and 10%) on the
Common Stock over the term of the options.  The potential realizable values set
forth above do not take into account applicable tax and expense payments that
may be associated with such options exercises.  Actual realizable value, if any,
will be dependent on the future price of the Common Stock on the actual date of
exercise, which may be earlier than the stated expiration date.  The 5% and 10%
assumed annualized rates of stock price appreciation over the exercise period of
the options used in the table above are mandated by the rules of the Securities
and Exchange Commission and do not represent the Company's estimate or
projection of the future price of the Common Stock on any date.  There is no
representation either express or implied that the stock price appreciation rates
for the Common Stock assumed for purposes of this table will actually be
achieved.

(2) Each option is subject to earlier termination if the officer's employment
with the Company is terminated for certain reasons.

Director Compensation

     Only non-employee directors of the Company ("Outside Directors") are
compensated for services as a director.  Commencing with the 1998 Annual
Meeting, each Outside Director will receive options to purchase 20,000 shares of
Common Stock when such person is elected a director and additional options to
purchase 20,000 shares of Common Stock on each anniversary of such date so long
as such person is continuing to serve as an Outside Director on such
anniversary.  In addition, each Outside Director will receive an annual retainer
of $12,000, and payments of  $2,000 for each meeting of the Board of Directors
that such director attends, $500 for each meeting of a committee of the Board of
Directors that such director attends and $1,000 for each telephonic meeting of
the Board of Directors in which he participates.

Compensation Committee Interlocks and Insider Participation

     During 1997, the Company's compensation committee determined the
compensation of all the Company's executive officers.  No member of the
compensation committee or executive officer of the Company has a relationship
that would constitute an interlocking relationship with the executive officers
or directors of another entity.

Employment Agreements

     On January 1, 1998, Mr. De Young entered into a new three-year employment
agreement with the Company.  The employment agreement provides that on each
anniversary of the agreement, the term shall be automatically extended for an
additional one-year period unless no later than six months before such
anniversary either party gives written notice to the other that it does not wish
to extend the term of the agreement.  The employment agreement provides for a
current annual base salary of $300,000 plus an annual bonus determined on the
basis of criteria established annually by the compensation committee of the
Board of Directors.  In the event of a Change of Control of the Company (as
defined in the employment agreement), Mr. De Young will be entitled to receive,
in addition to certain other benefits, a payment (the "Change of Control
Payment") equal to the sum of (i) the base salary otherwise payable during the
remainder of the term had the Change of Control not occurred and (ii) an amount
equal to the product of (x) the average of the annual bonuses earned in each of
the last two years (the "Average Bonus") and (y) the number of full and partial
years remaining in the term of the agreement.  In no event will the Change of
Control Payment be less than three times the sum of the annual base salary then
in effect and the Average Bonus (which Average Bonus shall not be less than 50%
of the base salary).

     In May 1996, Mr. Stoller entered into an employment agreement with the
Company which provides for annual compensation of $300,000.  Mr. Stoller ceased
to serve as Chairman of the Company on April 7, 1998 but will be entitled to
receive compensation through July 30, 1998.  The employment agreement provides
that Mr. Stoller has the right to receive a $600,000 payment in the event of a
Change of Control during the term.

     On January 1, 1998, Messrs. Kogler, Lavey, Conrath and McDonnell and Mses.
Straw and Ryan each entered into a new 18-month employment agreement with the
Company.  Each employment agreement provides that on each anniversary of such
agreement, the term shall be automatically extended for an additional one-year
period unless no later than six months before such anniversary either party
gives written notice to the other that it does not wish to extend the term of
the agreement.  The employment agreements for Messrs. Kogler, Lavey, Conrath and
McDonnell and for Mses. Straw and Ryan provide for an annual base salary of
$225,000, $175,000, $140,000, $142,830, $158,000, and $150,000 respectively,
plus an annual bonus determined on the basis of criteria established annually by
the compensation committee of the Board of Directors.  In the event of a Change
of Control, each of Messrs. Kogler, Lavey, Conrath and McDonnell and Mses. Straw
and Ryan will be entitled to receive, in addition to certain other benefits, a
Change of Control Payment equal to the sum of (i) the base salary otherwise
payable during the remainder of the term had the Change of Control not occurred
and (ii) an amount equal to the product of (x) the Average Bonus and (y) the
number of full and partial years remaining in the term of the agreement.  In no
event will the Change of Control Payment be less than three times the sum of the
annual base salary then in effect and the Average Bonus (which Average Bonus
shall not be less than 50% of the base salary).

     In January 1998, the Company entered into agreements with each of Messrs.
De Young, Kogler, Lavey, Conrath and McDonnell and Mses. Straw and Ryan
providing for a payment in the event of a Change of Control in an amount equal
to the product of (i) 157,895 in the case of Mr. De Young, 75,188 in the case of
Mr. Kogler, 46,992 in the case of Mr. Lavey, 30,075 in the case of Mr. Conrath,
30,075 in the case of Mr. McDonnell, 46,617 in the case of Ms. Straw and 30,075
in the case of Ms. Ryan and (ii) the difference between (x) the closing price of
the Company's Common Stock on the date on which the stockholders of the Company
approve an amendment (the "Amendment") to the Company's Stock Option Plan
increasing the number of shares of Common Stock for which options may be granted
under the plan (the "Amendment Approval Price") and (y) $33.25.  In the event
of the occurrence of a Change of Control prior to the approval of the Amendment,
the Amendment Approval Price will be replaced with the highest per share price
actually paid to the Company's stockholders in connection with the Change of
Control.  Each of the agreements will terminate if the Amendment is not approved
by the stockholders of the Company by June 30, 1999.

     In the event the executive officers are required to pay an excise tax on
"excess parachute payments" received from the Company upon a Change of Control,
the Company has agreed to pay to the executive an amount necessary to place the
executive in the same after-tax financial position as the executive would have
been in had the executive not incurred such tax.

     Effective as of January 1, 1996, the Company entered into agreements with
each of its executive officers (other than Mr. Lavey and Ms. Ryan) providing
that, upon such officer's exercise of stock options granted in exchange for
options previously granted by CDI, the Company will pay to such officer an
amount equal to the tax savings actually recognized by the Company as a result
of the deductions attributable to such exercise.  In no event can the payment to
be received by an executive officer under such agreement exceed the difference
between the federal income tax actually paid by such officer as a result of such
option exercise and the amount of federal income tax that would have been paid
by such officer had such option exercise been taxed at the capital gains rate.

Compensation Committee Report

     The Company's executive compensation program is focused on shareholder
value, the overall performance of the Company, success of the Company as
impacted by the executive's performance and the performance of the individual
executive.

     The Compensation Committee's objective is to provide competitive levels of
compensation to the Company's executive officers that are integrated with the
Company's long-term performance goals, reward above-average corporate
performance, recognize individual initiative and achievements and assist the
Company in attracting and retaining qualified executives.  The compensation
policies and programs utilized by the Compensation Committee have been reviewed
with independent compensation consultants and endorsed by the Board of Directors
and generally consists of the following:

                                       14
<PAGE>
 
          (i)   Provide executive officer total compensation in relation to
          Company performance;

          (ii)  Provide a compensation program competitive with that received by
          executives of comparable companies in the solid waste industry in
          order to attract, motivate, and retain qualified personnel;

          (iii) Provide a management tool for focusing and directing the
          energies of key executives toward achieving individual and corporate
          objectives; and

          (iv)  Provide long-term incentive compensation in the form of stock
          option awards to link individual success to that of the Company.

     The Company's executive compensation consists of three key components: base
salary, annual incentive compensation in the form of cash bonuses, and stock
options, each of which is intended to complement the others and, taken together,
to satisfy the Company's compensation objectives.  The Compensation Committee's
policies with respect to each of the three components are discussed below.

     Base Salary.  Each fiscal year the Compensation Committee, along with the
Chief Executive Officer reviews and approves the annual salaries for the
Company's executive officers.  Many factors are included in determining base
salaries, such as the responsibilities borne by the executive officer, the scope
of the position, length of service with the Company and corporate and individual
performance.

     Cash Bonuses.  The Compensation Committee provides annual incentives to the
Company's executive officers in the form of cash bonuses.  These bonuses are
discretionary and are based on (i) the financial success of the Company and the
individual's contribution to such achievements, and (ii) certain subjective
factors established from time to time by the Compensation Committee.

     Stock Options.  The primary objective of the stock option program is to
link the interests of the Company's executive officers and other selected
employees to the stockholders through significant grants of stock options made
at the discretion of the Compensation Committee.  The Company's Stock Option
Plan authorizes the issuance of both incentive and non-qualified stock options
to officers and key employees of the Company.  Subject to general limits
prescribed by the plan, the Compensation Committee has the authority to
determine the individuals to whom stock options are awarded and the terms of the
options and the number of shares subject to each option.  The size of any
particular stock option award is based upon position and the individual
performance during the related evaluation period.

     Chief Executive Officer's Compensation.  As discussed under "Executive
Compensation-- Employment Agreements," the Company entered into a new employment
agreement with Mr. De Young in January 1998. Mr. De Young's 1997 salary was
based on an employment agreement 

                                       15
<PAGE>
 
entered into in May 1996, which was prior to the formation of the Compensation
Committee. The bonus and stock option grants to Mr. De Young in 1997 were based
on the Compensation Committee's consultation with independent compensation
consultants, a review of the compensation paid to the chief executive officers
of comparable companies, assessment of the Company's record revenue and earnings
growth, the success of the Company's acquisition program as well as the
Compensation Committee's continued recognition of Mr. De Young's leadership of
the Company.

                                   PROPOSAL 2
                                  APPROVAL OF
                      THE AMERICAN DISPOSAL SERVICES, INC.
                  AMENDED AND RESTATED 1996 STOCK OPTION PLAN


     The affirmative vote of the holders of at least a majority of the shares of
Common Stock present and entitled to vote at the meeting is required to approve
the Amended and Restated American Disposal Services, Inc. 1996 Stock Option Plan
(the "Plan").  The principal changes effected by the amendment and restatement
are (i) to increase the number of shares of the Company's Common Stock for which
options may be granted under the Plan to the greater of 3,500,000 shares or 15%
of the aggregate number of shares of Common Stock issued and outstanding and
(ii) to provide for the grant of options to directors of the Company who are not
employees of the Company.  Under the Plan as currently in effect, options to
purchase 1,600,000 shares of Common Stock were subject to grant, all of which
have been granted.  The Compensation Committee and the Board of Directors have
each approved the Amended and Restated 1996 Stock Option Plan.  In the absence
of instructions to the contrary, the shares of Common Stock represented by a
proxy delivered to the Board of Directors will be voted FOR the Amended and
Restated 1996 Stock Option Plan.


                       THE BOARD OF DIRECTORS RECOMMENDS
                     A VOTE "FOR" THE PROPOSAL TO APPROVE
                THE AMENDED AND RESTATED 1996 STOCK OPTION PLAN

     The Board of Directors has adopted the Plan and directed that it be
submitted to the stockholders for approval.  The following description is
qualified in its entirety by the provisions of the Plan, a copy of which is
annexed hereto as Exhibit A.

     Purpose.  The purpose of the Plan is to enhance the profitability and value
of the Company for the benefit of the Company's stockholders by enabling the
Company to offer employees and consultants of the Company or its Affiliates (as
defined in the Plan), as well as directors of the Company who are not employees
of the Company ("Non-Employee Directors"), options ("Stock Options") to purchase
Common Stock.  The intent of such offering is to create a means to raise the
level of stock ownership by these persons in order to attract, retain and reward
them and strengthen the mutuality of interests between them and the Company's
stockholders.

     Term.   The Plan has been adopted by the Board of Directors effective as of
May 14, 1998 (the "Effective Date"), subject to and conditioned upon stockholder
approval at the Annual Meeting of Stockholders.

     Administration.  The Plan will be administered by a committee or
subcommittee of the Board of Directors appointed from time to time by the Board
(the "Committee"), consisting of 

                                       17
<PAGE>
 
two or more directors qualified as "non-employee directors" under Rule 16b-3
promulgated under the Securities Exchange Act of 1934 ("Rule 16b-3"), as
amended, and "outside directors" under Section 162(m) of the Code ("Section
162(m)"). All questions of interpretation and application of the Plan will be
determined by the Committee.

     Participation.  All employees and consultants of the Company and its
Affiliates, and all Non-Employee Directors (collectively, the "Participants"),
are eligible to receive Stock Options, and the actual recipients who are
employees (including executive officers) and consultants will be determined by
the Committee.

     Shares of Stock Available for Grant.  The Plan currently provides that the
total number of shares of Common Stock subject to Stock Options is 1,600,000
shares.  The Plan, as amended and restated, provides that the aggregate number
of shares of Common Stock subject to Stock Options may not exceed the greater of
(i) 3,500,000 shares or (ii) 15% of the aggregate number of shares of Common
Stock issued and outstanding.  In addition, the maximum number of shares of
Common Stock with respect to which Stock Options may be granted during any
calendar year of the Company to any employee is 750,000 shares (both limitations
being subject to adjustment by the Committee, in the event of stock dividend,
stock split or any other change in capital structure or business of the
Company).  If any stock option expires, terminates or is canceled for any reason
without having been exercised in full, the number of shares of Common Stock
underlying any unexercised option will again be available under the Plan.  To
the extent that shares of Common Stock for which Stock Options are permitted may
be granted to a Participant during a calendar year of the Company are not
covered by a grant of a Stock Option in the Company's calendar year, such shares
of Common Stock will be available for grant or issuance to the Participant in
any subsequent calendar year during the term of the Plan.

     Stock Options.  The Plan provides for the grant of incentive stock options
("ISOs") and nonqualified stock options ("NQSOs").  The Committee will have the
full authority to grant to any employee of the Company or a majority-owned
subsidiary one or more ISOs, NQSOs or both types of Stock Options.  The
Committee will also have the full authority to grant to any employee of another
Affiliate of the Company or a Consultant one or more NQSOs.

     The exercise price per share of Common Stock subject to a Stock Option will
be determined by the Committee, at the time of grant, but may not be less than
100% of the fair market value of a share of Common Stock at the time of grant;
provided, however, that if an ISO is granted to a ten percent stockholder of the
Company or its subsidiaries ("Ten Percent Stockholder"), the exercise price per
share may be no less than 110% of the fair market value of the Common Stock.
The term of such Stock Option will be fixed by the Committee, but no Stock
Option will be exercisable more than 10 years after the date the Stock Option is
granted; provided, however, that the term of an ISO granted to a Ten Percent
Stockholder may not exceed five years.

     The Plan does not currently provide for the issuance of options to Non-
Employee Directors.  One of the purposes of the proposed amendment and
restatement is to allow Non-

                                       18
<PAGE>
 
Employee Directors to be compensated for their services as a director of the
Company through the issuance of the Company's securities, thereby providing a
performance incentive to Non-Employee Directors. Each Non-Employee Director
would receive NQSOs to purchase 20,000 shares of Common Stock upon election to
the Board of Directors and additional NQSOs to purchase 20,000 shares of Common
Stock on each anniversary of such date so long as such person is continuing to
serve as a Non-Employee Director on such anniversary. All of such NQSOs would
vest immediately upon grant, and the exercise price of such options would be the
fair market value of the Common Stock on the date of grant.

     On January 15, 1998, the Compensation Committee granted, subject to the
approval of the Amended and Restated 1996 Stock Option Plan by the stockholders
of the Company at the 1998 Annual Meeting of Stockholders, Stock Options under
the Plan to Messrs. De Young, Lavey, Kogler, Conrath and McDonnell and Mses.
Straw and Ryan to purchase 157,895, 46,992, 75,188, 30,075, 30,075, 46,617 and
30,075 shares of Common Stock, respectively, at an exercise price equal to the
closing price of the Company's Common Stock on the NASDAQ National Market System
on the date of the 1998 Annual Meeting of Stockholders.

     Federal Tax Consequences.  The rules concerning the federal income tax
consequences with respect to Stock Options are highly technical.  In addition,
the applicable statutory provisions are subject to change and their application
may vary in individual circumstances.  Therefore, the following is designed to
provide a general understanding of the federal income tax consequences; it does
not set forth any state or local income tax or estate tax consequences that may
be applicable.

     Incentive Stock Options.  Stock Options granted under the Plan may be
"incentive stock options" as defined in the Code, provided that such Stock
Options satisfy the requirements under the Code therefor.  In general, neither
the grant nor the exercise of an ISO will result in taxable income to the
Participant or a deduction to the Company.  The sale of Common Stock received
pursuant to the exercise of a Stock Option which satisfied all the requirements
of an ISO, as well as the holding period requirement described below, will
result in a long-term capital gain or loss to the optionee equal to the
difference between the amount realized on the sale and the exercise price and
will not result in a tax deduction to the Company.  To receive ISO treatment,
the Participant must not dispose of the Common Stock purchased pursuant to the
exercise of a Stock Option either (i) within two years after the Stock Option is
granted or (ii) within one year after the date of exercise.  If the Common Stock
is held for more than eighteen months after the date of exercise the Participant
will be taxed at a lower rate applicable to capital gains for such Participant.
Capital gains rates may be further reduced in the case of a longer holding
period.

     If all requirements for ISO treatment other than the holding period rules
are satisfied, the recognition of income by the Participant is deferred until
disposition of the Common Stock, but, in general, any gain (in an amount equal
to the lesser of (i) the fair market value of the Common Stock on the date of
exercise (or, with respect to officers, the date that sale of such stock would
not create liability ("Section 16(b) liability") under Section 16(b) of the
Exchange Act) minus the exercise price or (ii) the amount realized on the
disposition minus the exercise price) is treated as 

                                       19
<PAGE>
 
ordinary income. Any remaining gain is treated as long-term or short-term
capital gain depending on the Participant's holding period for the stock
disposed of. The Company generally will be entitled to a deduction at that time
equal to the amount of ordinary income realized by the Participant.

     The Plan provides that a Participant may pay for Common Stock received upon
the exercise of a Stock Option (including an ISO) with other shares of Common
Stock held for at least six months.  In general a Participant's transfer of
stock acquired pursuant to the exercise of an ISO, to acquire other stock in
connection with the exercise of an ISO may result in ordinary income if the
transferred stock has not met the minimum statutory holding period necessary for
favorable tax treatment as an ISO.  For example, if a Participant exercises an
ISO and uses the stock so acquired to exercise another ISO within the two-year
or one-year holding periods discussed above, the Participant may realize
ordinary income under the rules summarized above.

     Non-Qualified Stock Options.  A Participant will realize no taxable income
at the time he or she is granted a NQSO.  Such conclusion is predicated on the
assumption that, under existing Treasury Department regulations, a NQSO, at the
time of its grant, has no readily ascertainable fair market value.  Ordinary
income will be realized when a NQSO is exercised.  The amount of such income
will be equal to the excess of the fair market value on the exercise date of the
shares of Common Stock issued to a Participant over the exercise price.  The
Participant's holding period with respect to the shares acquired will begin on
the date of exercise.

     The tax basis of the Common Stock acquired upon the exercise of any NQSO
will be equal to the sum of (i) the exercise price of such NQSO and (ii) the
amount included in income with respect to such NQSO.  Any gain or loss on a
subsequent sale of the Common Stock will be either a long-term or short-term
capital gain or loss, depending on the Participant's holding period for the
Common Stock disposed of. Subject to the limitation under Sections 162(m) and
280G of the Code (as described below), the Company generally will be entitled to
a deduction for federal income tax purposes at the same time and in the same
amount as the Participant is considered to have realized ordinary income in
connection with the exercise of the NQSO.

     Certain Other Tax Issues.  In addition, (i) officers of the Company subject
to Section 16(b) liability may be subject to special rules regarding the income
tax consequences concerning their awards; (ii) any entitlement to a tax
deduction on the part of the corporation is subject to the applicable federal
tax rules (including, without limitation, Section 162(m) of the Code regarding
the $1,000,000 limitation on deductible compensation); (iii) in the event that
the exercisability or vesting of any award is accelerated because of an
Extraordinary Transaction (as defined in the Plan), payments relating to the
awards (or a portion thereof), either alone or together with certain other
payments, may constitute parachute payments under Section 280G of the Code,
which excess amounts may be subject to excise taxes and may be nondeductible by
the Company; and (iv) the exercise of an ISO may have implications in the
computation of alternative minimum taxable income.

     In general, Section 162(m) of the Code denies a publicly held corporation a
deduction for federal income tax purposes for compensation in excess of
$1,000,000 per year per person to its 

                                       20
<PAGE>
 
chief executive officer and the four other officers whose compensation is
disclosed in its proxy statement, subject to certain exceptions. Stock Options
will generally qualify under one of these exceptions if they are granted under a
plan that states the maximum number of shares with respect to which options may
be granted to any employee during a specified period and the plan under which
the options are granted is approved by stockholders and is administered by a
compensation committee comprised of outside directors. The Plan is intended to
satisfy these requirements with respect to Stock Options.

     The Plan is not subject to any of the requirements of the Employee
Retirement Income Security Act of 1974, as amended.  The Plan is not, nor is it
intended to be, qualified under Section 401(a) of the Code.

     Termination or Amendment of Plan.  Notwithstanding any other provision of
the Plan, the Committee may at any time, and from time to time, amend,
prospectively or retroactively, in whole or in part, any or all of the
provisions of the Plan, or suspend or terminate it entirely, retroactively or
otherwise; provided, however, that, unless otherwise required by law or
specifically provided in the Plan, the rights of a Participant with respect to
Stock Options granted prior to such amendment, suspension or termination, may
not be impaired without the consent of such Participant; and provided further,
without the approval of the stockholders of the Company in accordance with the
laws of the State of Delaware, to the extent required by the applicable
provisions of Rule 16b-3 or Section 162(m), or with respect to ISOs, Section 422
of the Code, no amendment may be made which would:  (a) increase the aggregate
number of shares of Common Stock that may be issued under the Plan; (b) increase
the maximum individual Participant limitations for a fiscal year under the Plan;
(c) change the classification of employees and Consultants eligible to receive
awards under the Plan; (d) decrease the minimum exercise price of any Stock
Option; or (e) extend the maximum option term under the Plan.

     Extraordinary Transaction.  In the event of an Extraordinary Transaction
(as defined in the Plan), the Committee may, in its sole discretion, terminate
all outstanding Stock Options, effective as of the date of the Extraordinary
Transaction, by delivering notice of termination to each such Participant at
least 30 days prior to the date of consummation of the Extraordinary
Transaction; provided, that during the period from the date on which such notice
of termination is delivered to the consummation of the Extraordinary
Transaction, each such Participant shall have the right to exercise in full all
his or her Stock Options that are then outstanding (whether vested or not
vested) but contingent on the occurrence of the Extraordinary Transaction;
provided, further, that, if the Extraordinary Transaction does not take place
within a specified period after giving such notice for any reason whatsoever,
the notice and exercise shall be null and void.

                                  PROPOSAL 3
                     RATIFICATION OF INDEPENDENT AUDITORS


     The Board of Directors has reappointed Ernst & Young LLP as the Company's
independent auditors for the fiscal year ending December 31, 1998.  In the
absence of instructions to the contrary, the shares of Common Stock represented
by a proxy delivered to the Board of Directors will be voted FOR the
ratification of the appointment of Ernst & Young LLP.


                       THE BOARD OF DIRECTORS RECOMMENDS
             A VOTE "FOR" THE RATIFICATION OF THE REAPPOINTMENT OF
                      THE COMPANY'S INDEPENDENT AUDITORS

     A representative of Ernst & Young LLP is expected to be present at the
Annual Meeting of Stockholders and will be available to respond to appropriate
questions and make such statements as he or she may desire.

Section 16(a) Beneficial Ownership Reporting Compliance

     Under the securities laws of the United States, the Company's directors,
officers, and any persons holding more than 10 percent of the Common Stock are
required to report their ownership of Common Stock and any changes in that
ownership, on a timely basis, to the Securities and Exchange Commission.  Based
on material provided to the Company, all such required reports were filed on a
timely basis in 1997 except that the Company's executive officers did not timely
file Form 5s reporting 1997 stock option grants.  All non-timely Form 5s have
now been filed.

material in relation to the annual meeting of the Company to be held in 1999
must submit the same in writing so as to be received at the executive office of
the Company on or before January 25, 1999.  Such proposals must also meet the
other requirements of the rules of the Securities and Exchange Commission
relating to stockholders' proposals.

                                ADMINISTRATION

     3.1.  The Committee.  This Plan shall be administered and interpreted by
the Committee.  Subject to the other provisions of this Plan, the Committee or
the Board, as applicable, shall have the authority to adopt, alter and repeal
such administrative rules governing this Plan and perform all acts, including
the delegation of its administrative responsibilities, as it shall, from time to
time, deem advisable; to construe and interpret this Plan and any Stock Option
granted hereunder (and any agreements relating thereto).  The Committee may
correct any defect, supply any omission or reconcile any inconsistency in this
Plan or in any agreement relating thereto in the manner and to the extent it
shall deem necessary to carry this Plan into effect, but only to the extent any
such action would be permitted under the applicable provisions of both Rule 
16b-3 and Section 162(m) of the Code. The Committee may adopt rules for persons
who are residing in, or subject to, the taxes of, countries other than the
United States to comply with applicable tax and securities laws. To the extent
applicable, this Plan is intended to comply with the applicable requirements of
Rule 16b-3 and Section 162(m) of the Code and shall be limited, construed and
interpreted in a manner so as to comply therewith. The Board, its directors, the
Committee, its members and any person to whom authority is delegated pursuant to
this Section 3.1 shall not be liable for any action or determination made in
good faith with respect to this Plan.

     3.2.  Awards.  The Committee shall have full authority to grant Stock
Options to Eligible Employees and Consultants and to otherwise administer this
Plan.  In particular, the Committee or the Board, as applicable, shall have the
authority:

          (a) to select Eligible Employees and Consultants to whom Stock Options
     may from time to time be granted hereunder;

          (b) to determine the number of shares of Common Stock to be covered by
     each Stock Option granted to an Eligible Employee or Consultant, and the
     terms and conditions of the Stock Option (including, but not limited to,
     the exercise or purchase price (if any), any restriction or limitation, any
     vesting schedule or acceleration thereof or any forfeiture restrictions or
     waiver thereof, regarding any Stock Option, and the shares of Common Stock
     relating thereto, based on such factors, if any, as the Committee shall
     determine in its sole discretion);

                                       4
<PAGE>
 
          (c) to modify or extend a Stock Option, subject to Section 8.1 herein;
     and

          (d) to offer to buy out a Stock Option previously granted, based on
     such terms and conditions as the Committee or the Board, as applicable,
     shall establish and communicate to the Participant at the time such offer
     is made.

     3.3.  Decisions Final.  Any decision, interpretation or other action made
or taken in good faith by or at the direction of the Company, the Board or the
Committee (or any of its members) arising out of or in connection with this Plan
shall be within the absolute discretion of the Company, the Board or the
Committee, as the case may be, and shall be final, binding and conclusive on the
Company and its Affiliates and all employees and Participants and their
respective heirs, executors, administrators, successors and assigns.

     3.4.  Reliance on Counsel.  The Company, the Board or the Committee may
consult with legal counsel, who may be counsel for the Company or other counsel,
with respect to its obligations or duties hereunder, or with respect to any
action or proceeding or any question of law, and shall not be liable with
respect to any action taken or omitted by it in good faith pursuant to the
advice of such counsel.  The Company, the Board or the Committee may also engage
consultants or agents with regard to the plan.  Expenses incurred by the
Committee or Board in the engagement of any such counsel, consultant or agent
shall be paid by the Company.

     3.5.  Procedures.  If the Committee is appointed, the Board shall designate
one of the members of the Committee as chairman and the Committee shall hold
meetings, subject to the By-Laws of the Company, at such times and places as the
Committee shall deem advisable.  A majority of the Committee members shall
constitute a quorum.  All determinations of the Committee shall be made by a
majority of its members.  Any decision or determination reduced to writing and
signed by all the Committee members in accordance with the By-Laws of the
Company shall be fully as effective as if it had been made by a vote at a
meeting duly called and held.


                                  ARTICLE IV.

                          SHARE AND OTHER LIMITATIONS

     4.1.  Shares.

           (a) The aggregate number of shares of Common Stock which may be
     issued and with respect to which Stock Options may be granted under this
     Plan shall not exceed the greater of (i) 3,500,000 shares or (ii) 15% of
     the aggregate number of shares of Common Stock issued and outstanding
     immediately after the grant of any Stock Option (subject to any increase or
     decrease pursuant to Section 4.2). Notwithstanding the foregoing, in no
     event may the aggregate number of shares of Common Stock which may be
     issued upon the exercise of Incentive Stock Options exceed 3,500,000 shares
     (subject to any increase or decrease

                                       5
<PAGE>
 
     pursuant to Section 4.2). Shares of Common Stock issued upon the exercise
     of Stock Options may be either authorized and unissued Common Stock or
     Common Stock held in or acquired for the treasury of the Company. If any
     Stock Option expires, terminates or is canceled for any reason without
     having been exercised in full, the number of shares of Common Stock
     underlying any unexercised Stock Option shall again be available under this
     Plan. In addition, in determining the number of shares of Common Stock
     available under the Plan other than for the granting of Incentive Stock
     Options, if Common Stock has been exchanged by a Participant as full or
     partial payment to the Company in connection with the exercise of a Stock
     Option, the number of shares of Common Stock exchanged as payment in
     connection with the exercise shall again be available under this Plan.

          (b) The maximum number of shares of Common Stock with respect to which
     Stock Options may be granted under this Plan during any calendar year of
     the Company to each Eligible Employee shall be 750,000 shares (subject to
     any increase or decrease pursuant to this Section 4.2). To the extent that
     shares of Common Stock for which Stock Options are permitted to be granted
     to a Participant pursuant to Section 4.1(b) during a calendar year of the
     Company are not covered by a grant of a Stock Option in the Company's
     calendar year, such shares of Common Stock shall be available for grant or
     issuance to the Participant in any subsequent calendar year during the term
     of this Plan.

     4.2.  Changes.

          (a) The existence of this Plan and the shares of Common Stock and
     Stock Options granted hereunder shall not affect in any way the right or
     power of the Board or the stockholders of the Company to make or authorize
     any adjustment, recapitalization, reorganization or other change in the
     Company's capital structure or its business, any merger or consolidation of
     the Company or Affiliates, any issue of bonds, debentures, preferred or
     prior preference stock ahead of or affecting Common Stock, the
     authorization or issuance of additional shares of Common Stock, the
     dissolution or liquidation of the Company or Affiliates, any sale or
     transfer of all or part of its assets or business or any other corporate
     act or proceeding.

          (b) In the event of any change in the capital structure or business of
     the Company by reason of any stock dividend, stock split or reverse stock
     split, recapitalization, reorganization, merger, consolidation, split-up,
     combination or exchange of shares, distribution with respect to its
     outstanding Common Stock or capital stock other than Common Stock,
     reclassification of its capital stock, any sale or transfer of all or part
     of the Company's assets or business, or any similar change affecting the
     Company's capital structure or business, and the Committee or the Board, as
     applicable, determines an adjustment is appropriate under this Plan, then
     the aggregate number and kind of shares which thereafter may be issued
     under this Plan, the number and kind of shares or other property (including
     cash) to be issued upon exercise of an outstanding Stock Option granted
     under this Plan and the purchase or exercise price thereof shall be
     appropriately adjusted consistent with such change in such manner as the
     Committee or the Board, as applicable, may deem equitable 

                                       6
<PAGE>
 
     to prevent substantial dilution or enlargement of the rights granted to, or
     available for, Participants under this Plan or as otherwise necessary to
     reflect the change, and any such adjustment determined by the Committee or
     the Board, as applicable, in good faith shall be binding and conclusive on
     the Company and all Participants and employees and their respective heirs,
     executors, administrators, successors and assigns.

          (c) Fractional shares of Common Stock resulting from any adjustment in
     Stock Options pursuant to Section 4.2(a) or (b) shall be aggregated until,
     and eliminated at, the time of exercise by rounding-down for fractions less
     than one-half and rounding-up for fractions equal to or greater than one-
     half.  No cash settlements shall be made with respect to fractional shares
     eliminated by rounding.  Notice of any adjustment shall be given by the
     Committee or the Board, as applicable, to each Participant whose Stock
     Option has been adjusted and such adjustment (whether or not such notice is
     given) shall be effective and binding for all purposes of this Plan.

          (d) In the event of (i) a merger or consolidation in which the Company
     is not the surviving entity or in which the Company is the surviving entity
     but the holders of the Common Stock outstanding immediately prior to the
     consummation of the transaction are not the holders of a majority of the
     Common Stock outstanding immediately subsequent to the transaction, or (ii)
     in the event of any transaction that results in the acquisition of all or
     substantially all of the Company's outstanding Common Stock by a single
     person or entity or by a group of persons and/or entities acting in
     concert, or in the event of the sale or transfer of all or substantially
     all of the Company's assets (all of the foregoing being referred to as
     "Extraordinary Transactions"), then in the event of an Extraordinary
     Transaction of the type described in clause (i) above, the Committee may,
     in its sole discretion, and in the event of an Extraordinary Transaction of
     the type described in clause (ii) above, the Committee shall, terminate all
     outstanding Stock Options, effective as of the date of the Extraordinary
     Transaction by delivering notice of termination to each such Participant at
     least 30 days prior to the date of consummation of the Extraordinary
     Transaction; provided, that during the period from the date on which such
     notice of termination is delivered to the consummation of the Extraordinary
     Transaction, each such Participant shall have the right to exercise in full
     all of his or her Stock Options that are then outstanding (whether vested
     or not vested) but contingent on the occurrence of the Extraordinary
     Transaction; provided, further, that, if the Extraordinary Transaction does
     not take place within a specified period after giving such notice for any
     reason whatsoever, the notice and exercise shall be null and void.  If an
     Extraordinary Transaction occurs, to the extent the Committee does not
     terminate the outstanding Stock Options pursuant to this Section 4.2(d),
     then the provisions of Section 4.2(b) shall apply.

     5.2.  Grants.  The Committee shall have the authority to grant to any
Eligible Employee one or more Incentive Stock Options, Non-Qualified Stock
Options, or both types of Stock Options.  To the extent that any Stock Option
does not qualify as an Incentive Stock Option (whether because of its provisions
or the time or manner of its exercise or otherwise), such Stock Option or the
portion thereof which does not so qualify, shall constitute a separate Non-
Qualified Stock Option.  The Committee shall have the authority to grant to any
Consultant one or more Non-Qualified Stock Options.  Notwithstanding any other
provision of this Plan to the contrary or any provision in an agreement
evidencing the grant of an Stock Option to the contrary, any Stock Option
granted to an Employee of an Affiliate (other than a Subsidiary), a Non-Employee
Director or a Consultant shall be a Non-Qualified Stock Option.

     5.3.  Terms of Stock Options.  Stock Options shall be subject to the
following terms and conditions, and shall be in such form and contain such
additional terms and conditions, not inconsistent with the terms of this Plan,
as the Committee shall deem desirable:

          (a) The exercise price per share of Common Stock of any Stock Option
     shall be determined by the Committee or the Board, as applicable, at the
     time of grant but shall not be less than 100% of the Fair Market Value of a
     share of Common Stock at the time of grant; provided, however, that if an
     Incentive Stock Option is granted to a Ten Percent Stockholder, the
     exercise price per share shall be no less than 110% of the Fair Market
     Value of the Common Stock.

          (b) The term of each Stock Option shall be fixed by the Committee, but
     no Stock Option shall be exercisable more than 10 years after the date the
     Stock Option is granted; provided, however, the term of an Incentive Stock
     Option granted to a Ten Percent Stockholder may not exceed five years.

          (c) Stock Options shall be exercisable at such time or times and
     subject to such terms and conditions as shall be determined by the
     Committee at the time of grant.  If the Committee provides, in its
     discretion, that any Stock Option is exercisable subject to certain
     limitations (including, without limitation, that it is exercisable only in
     installments or within certain time periods), the Committee may waive such
     limitations on the exercisability at any time at or after the time of grant
     in whole or in part, based on such factors, if any, as the Committee shall
     determine in its sole discretion.

                                       8
<PAGE>
 
          (d) Subject to whatever installment exercise and waiting period
     provisions apply under Section 6.3(c), Stock Options may be exercised in
     whole or in part at any time during the Stock Option term, by giving
     written notice of exercise to the Company specifying the number of shares
     to be purchased.  Common Stock purchased pursuant to the exercise of a
     Stock Option shall be paid for at the time of exercise as follows: (i) in
     cash or by check, bank draft or money order payable to the order of
     Company; (ii) if the Common Stock is traded on a national securities
     exchange, the Nasdaq Stock Market, Inc. or quoted on a national quotation
     system sponsored by the National Association of Securities Dealers, through
     the delivery of irrevocable instructions to a broker to deliver promptly to
     the Company an amount equal to the purchase price; or (iii) on such other
     terms and conditions as may be acceptable to the Committee (which may
     include payment in full or part in the form of Common Stock owned by the
     Participant (and for which the Participant has good title free and clear of
     any liens and encumbrances) based on the Fair Market Value of the Common
     Stock on the payment date as determined by the Committee or the surrender
     of vested Stock Options owned by the Participant).  No shares of Common
     Stock shall be issued until payment therefor, as provided herein, has been
     made or provided for.

          (e) To the extent that the aggregate Fair Market Value (determined as
     of the time of grant) of the Common Stock with respect to which Incentive
     Stock Options are exercisable for the first time by an Eligible Employee
     during any calendar year under this Plan and/or any other stock option plan
     of the Company, any Subsidiary or any parent corporation (within the
     meaning of Section 424(e) of the Code) exceeds $100,000, such Stock Options
     shall be treated as Non-Qualified Stock Options.  In addition, if an
     Eligible Employee's employment by the Company, a Subsidiary or a parent
     corporation (within the meaning of Section 424(e) of the Code) terminates
     more than three months prior to the date of exercise (or such other period
     as required by applicable law), such Stock Option shall be treated as a
     Non-Qualified Stock Option.  Should the foregoing provision not be
     necessary in order for the Stock Options to qualify as Incentive Stock
     Options, or should any additional provisions be required, the Committee may
     amend this Plan accordingly, without the necessity of obtaining the
     approval of the stockholders of the Company.

          (f) Subject to the terms and conditions of this Plan, a Stock Option
     shall be evidenced by such form of agreement or grant as is approved by the
     Committee and the Committee may modify, extend or renew outstanding Stock
     Options granted under this Plan (provided that the rights of a Participant
     are not reduced without his consent), or accept the surrender of
     outstanding Stock Options (up to the extent not theretofore exercised) and
     authorize the granting of new Stock Options in substitution therefor (to
     the extent not theretofore exercised).

          (g) Stock Options may contain such other provisions, which shall not
     be inconsistent with any of the foregoing terms of this Plan, as the
     Committee shall deem appropriate including, without limitation, permitting
     "reloads" such that the same number of Stock Options are granted as the
     number of Stock Options exercised, shares used to pay for the exercise
     price of Stock Options or shares used to pay withholding taxes ("Reloads").

                                       9
<PAGE>
 
     With respect to Reloads, the exercise price of the new Stock Option shall
     be the Fair Market Value on the date of the "reload" and the term of the
     Stock Option shall be the same as the remaining term of the Stock Options
     that are exercised, if applicable, or such other exercise price and term as
     determined by the Committee.


                                  ARTICLE VI.

                      NON-EMPLOYEE DIRECTOR STOCK OPTIONS

     6.1.  Stock Options.  The terms of this Article VI shall apply only to
Stock Options granted to Non-Employee Directors.

     6.2. Grants.  On the date that a Non-Employee Director is first elected a
director of the Company, and on each anniversary of such date while shares of
Common Stock remain available for the grant of Stock Options hereunder, each
Non-Employee Director shall be automatically granted Stock Options to purchase
20,000 shares of Common Stock.

     6.3.  Non-Qualified Stock Options.  Stock Options granted under this
Article VI shall be Non-Qualified Stock Options.

     6.4.  Terms of Options.  Stock Options granted under this Article VI shall
be subject to the following terms and conditions and shall be in such form and
contain such additional terms and conditions, not inconsistent with terms of
this Plan, as the Board shall deem desirable:

          (a) The exercise price per share of Common Stock subject to a Stock
     Option granted pursuant to Section 6.2 shall be equal to 100% of the Fair
     Market Value of Common Stock at the time of grant.

          (b) Stock Options granted under this Article VI shall be exercisable
     immediately upon grant.

          (c) A Non-Employee Director electing to exercise one or more Stock
     Options shall give written notice of exercise to the Company specifying the
     number of shares to be purchased.  Common Stock purchased pursuant to the
     exercise of a Stock Option shall be paid for as provided in Section 5.3(d).
     No shares of Common Stock shall be issued until payment therefore, as
     provided herein, has been made or provided for.

          (d) Except as otherwise provided herein, if not previously exercised
     each Stock Option shall expire upon the tenth anniversary of the date of
     the grant thereof.

          (e) Stock Options granted to a Non-Employee Director under this
     Article VI shall be subject to Section 4.2.

                                       10
<PAGE>
 
     6.5.  Termination of Directorship.  The following rules apply with regard
to Stock Options granted under this Article VI upon a Termination of
Directorship:

          (a) Except as otherwise provided herein, upon a Termination of
     Directorship on account of death or Disability, all then outstanding Stock
     Options shall remain exercisable by the Participant or, in the case of
     death, by the Participant's estate or by the person given authority to
     exercise such Stock Options by his or her will or by operation of law, at
     any time within a period of one year from the date of such Termination of
     Directorship, but in no event beyond the expiration of the stated term of
     such Stock Option.

          (b) Except as otherwise provided herein, upon a Termination of
     Directorship, on account of retirement, resignation, failure to stand for
     reelection or failure to be reelected or otherwise other than as set forth
     in (c) below, all then outstanding Stock Options shall remain exercisable
     by the Participant at any time within a period of one year from the date of
     such Termination of Directorship, but in no event beyond the expiration of
     the stated term of such Stock Option.

          (c) Upon removal, failure to stand for reelection or failure to be
     renominated for any reason that would constitute grounds for removal of a
     director for cause under Delaware law, or if the Company obtains or
     discovers information after Termination of Directorship that such
     Participant had engaged in conduct that would have justified removal for
     cause during his or her directorship, all outstanding Stock Options of such
     Participant shall immediately terminate and shall be null and void.


                                 ARTICLE VII.

                    NON-TRANSFERABILITY AND TERMINATION OF
                       EMPLOYMENT/CONSULTANCY PROVISIONS

     7.1.  Except as otherwise provided in this Section 7.1, no Stock Option
shall be Transferred by the Participant otherwise than by will or by the laws of
descent and distribution.  All Stock Options shall be exercisable, during the
Participant's lifetime, only by the Participant.  Any attempt to Transfer any
Stock Option shall be void, and no such Stock Option shall in any manner be used
for the payment of, subject to, or otherwise encumbered by or hypothecated for
the debts, contracts, liabilities, engagements or torts of any person who shall
be entitled to such Stock Option, nor shall it be subject to attachment or legal
process for or against such person.  Notwithstanding the foregoing, the
Committee may determine at the time of grant or thereafter that a Non-Qualified
Stock Option granted pursuant to Article V or Article VI that is otherwise not
transferable pursuant to this Article VII is transferable in whole or part and
in such circumstances, and under such conditions, as specified by the Committee.

                                       11

     7.2.  Termination of Employment or Termination of Consultancy.  The
following rules apply with regard to Stock Options upon the Termination of
Employment or Termination of Consultancy of a Participant, unless otherwise
determined by the Committee at grant or, if no rights of the Participant (or his
estate in the event of death) are reduced, thereafter:

          (a) If a Participant's Termination of Employment or Termination of
     Consultancy is by reason of his death, any Stock Option held by such
     Participant may be exercised, to the extent exercisable at the
     Participant's Termination of Employment or Termination of Consultancy, by
     the Participant's estate or by the person given authority to exercise such
     Stock Options by his or her will or by operation of law, at any time within
     a period of one year from the date of such death, but in no event beyond
     the expiration of the stated term of such Stock Option.

          (b) If a Participant's Termination of Employment or Termination of
     Consultancy is by reason of his  Disability or retirement, any Stock Option
     held by such Participant may be exercised, to the extent exercisable at the
     Participant's Termination of Employment or Termination of Consultancy, by
     the Participant, at any time within a period of one year from the date of
     such Termination of Employment or Termination of Consultancy, but in no
     event beyond the expiration of the stated term of such Stock Option;
     provided, however, that, if the Participant dies within such exercise
     period, any unexercised Stock Option held by such Participant shall
     thereafter be exercisable by the Participant's estate or by the person
     given authority to exercise such Stock Options by his or her will or by
     operation of law, to the extent to which it was exercisable at the time of
     death, for a period of one year (or such other period as the Committee may
     specify at grant or, if no rights of the Participant's estate are reduced,
     thereafter) from the date of such death, but in no event beyond the
     expiration of the stated term of such Stock Option.

          (c) If a Participant's Termination of Employment or Termination of
     Consultancy is by the Company without cause, any Stock Option held by such
     Participant may be exercised, to the extent exercisable at termination, by
     the Participant at any time within a period of 90 days from the date of
     such termination, but in no event beyond the expiration of the stated term
     of such Stock Option.

          (d) If a Participant's Termination of Employment or Termination of
     Consultancy is a voluntary termination by the Participant and occurs prior
     to, or more than 90 days after, the occurrence of an event which would be
     grounds for Termination of Employment or Termination of Consultancy for
     cause (without regard to any notice or cure period requirements), any Stock
     Option held by such Participant may be exercised, to the extent exercisable
     at termination, by the Participant at any time within a period of 30 days
     from the date of such termination, but in no event beyond the expiration of
     the stated term of such Stock Option.

          (e) If a Participant's Termination of Employment or Termination of
     Consultancy is: (i) for cause, or (ii) a voluntary termination (as
     provided in subsection (d) above) within 

                                       12
<PAGE>
 
     90 days after an event which would be grounds for a Termination of
     Employment or Termination of Consultancy for cause, any Stock Option held
     by such Participant shall thereupon terminate and expire as of the date of
     termination.


                                 ARTICLE VIII.

                       TERMINATION OR AMENDMENT OF PLAN

     8.1.  Termination or Amendment.  Notwithstanding any other provision of
this Plan, the Board or the Committee may at any time, and from time to time,
amend, in whole or in part, any or all of the provisions of this Plan (including
any amendment deemed necessary to ensure that the Company may comply with any
regulatory requirement referred to in this Article VIII), or suspend or
terminate it entirely, retroactively or otherwise; provided, however, that,
unless otherwise required by law or specifically provided herein, the rights of
a Participant with respect to Stock Options granted prior to such amendment,
suspension or termination, may not be impaired without the consent of such
Participant; and provided further, without the approval of the stockholders of
the Company in accordance with the laws of the State of Delaware, to the extent
required by the applicable provisions of Rule 16b-3 or Section 162(m) of the
Code, or with respect to Incentive Stock Options, Section 422 of the Code, no
amendment may be made which would: (a) increase the aggregate number of shares
of Common Stock that may be issued under this Plan; (b) increase the maximum
individual Participant limitations for a fiscal year under Section 4.1(b); (c)
change the classification of employees and Consultants eligible to receive
Awards under this Plan; (d) decrease the minimum exercise price of any Stock
Option; (e) extend the maximum option term under Section 5.3(b); or (f)
reprice any outstanding Stock Option.

     The Committee may amend the terms of any Award theretofore granted,
prospectively or retroactively, but, subject to Article IV or as otherwise
specifically provided herein, no such amendment or other action by the Committee
shall impair the rights of any Participant without the Participant's consent.


                                  ARTICLE IX.

                                 UNFUNDED PLAN

     9.1.  Unfunded Status of Plan.  This Plan is intended to constitute an
"unfunded" plan for incentive and deferred compensation.  With respect to any
payments as to which a Participant has a fixed and vested interest but which are
not yet made to a Participant by the Company, nothing contained herein shall
give any such Participant any rights that are greater than those of a general
creditor of the Company.

                                       13
<PAGE>
 
                                   ARTICLE X.

                              GENERAL PROVISIONS

     10.1.  Legend.  All certificates for shares of Common Stock delivered under
this Plan shall be subject to such stock transfer orders and other restrictions
as the Committee or the Board, as applicable, may deem advisable under the
rules, regulations and other requirements of the Securities and Exchange
Commission, any stock exchange upon which the Common Stock is then listed or any
national securities association system upon whose system the Common Stock is
then quoted, any applicable Federal or state securities law, and any applicable
corporate law, and the Committee or the Board, as applicable, may cause a legend
or legends to be put on any such certificates to make appropriate reference to
such restrictions.

     10.2.  Other Plans.  Nothing contained in this Plan shall prevent the Board
from adopting other or additional compensation arrangements, subject to
stockholder approval if such approval is required; and such arrangements may be
either generally applicable or applicable only in specific cases.

     10.3.  No Right to Employment/Consultancy/Directorship.  Neither this Plan
nor the grant of any Stock Options hereunder shall give any Participant or other
employee or Consultant any right with respect to continuance of employment or
consultancy by the Company or any Affiliate, nor shall they be a limitation in
any way on the right of the Company or any Affiliate by which an employee is
employed or consultant retained to terminate his employment or consultancy, as
applicable, at any time.  Neither this Plan nor the grant of any Stock Options
or shares of Common Stock hereunder shall impose any obligations on the Company
to retain any Participant as a director nor shall it impose on the part of any
Participant any obligation to remain as a director of the Company.

     10.4.  Withholding of Taxes.  The Company shall deduct from any payment to
be made to a Participant, or shall otherwise require, prior to the issuance or
delivery of any shares of Common Stock or the payment of any cash hereunder,
payment by the Participant of any Federal, state or local taxes required by law
to be withheld; and such withholding is hereby approved by the Committee.

     10.5.  Governing Law.  This Plan shall be governed and construed in
accordance with the laws of the State of Delaware (regardless of the law that
might otherwise govern under applicable Delaware principles of conflict of
laws).

     10.6.  Construction.  Wherever any words are used in this Plan in the
masculine gender they shall be construed as though they were also used in the
feminine gender in all cases where they would so apply, and wherever any words
are used herein in the singular form they shall be construed as though they were
also used in the plural form in all cases where they would so apply.  To the
extent applicable, this Plan shall be limited, construed and interpreted in a
manner so as to comply with Section 162(m) of the Code and the applicable
requirements of Rule 16b-3; provided, however, 

                                       14
<PAGE>
 
that noncompliance with Section 162(m) of the Code and Rule 16b-3 shall have no
impact on the effectiveness of a Stock Option under this Plan.

     10.7.  Other Benefits.  No Stock Option under this Plan shall be deemed
compensation for purposes of computing benefits under any retirement plan of the
Company or its subsidiaries or affiliates nor affect any benefits under any
other benefit plan now or subsequently in effect under which the availability or
amount of benefits is related to the level of compensation.

     10.8.  Costs.  The Company shall bear all expenses included in
administering this Plan, including expenses of issuing shares of Common Stock
pursuant to this Plan or any Stock Options granted hereunder.

     10.9.  No Right to Same Benefits.  The provisions of Stock Options need not
be the same with respect to each Participant, and such Stock Options to
individual Participants need not be the same in subsequent years.

     10.10.  Death/Disability.  The Committee or the Board, as applicable, may
in its discretion require the transferee of a Participant's Stock Option to
supply the Company with written notice of the Participant's death or Disability
and to supply the Company with a copy of the will (in the case of the
Participant's death) or such other evidence as the Committee or the Board, as
applicable, deems necessary to establish the validity of the Transfer of a Stock
Option.  The Committee or the Board, as applicable, may also require that the
transferee agree in writing to be bound by all of the terms and conditions of
this Plan.

     10.11.  Severability of Provisions.  If any provision of this Plan shall be
held invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provisions hereof, and this Plan shall be construed and
enforced as if such provisions had not been included.

     10.12.  Headings and Captions.  The headings and captions herein are
provided for reference and convenience only, shall not be considered part of
this Plan, and shall not be employed in the construction of this Plan.


                                  ARTICLE XI.
