                      VOTING SECURITIES AND VOTING RIGHTS

  Holders of shares of Common Stock, par value $.001 per share (the "Shares"),
and holders of shares of Series B and Series C Convertible Preferred Stock,
par value $.001 per share (the "Preferred Shares"), of record as of the close
of business on January 21, 2000, are entitled to notice of, and to vote at,
the Annual Meeting on all matters except that the holders of the Preferred
Shares are not entitled to vote for the election of directors. Except as set
forth in the preceding sentence, each outstanding Share is entitled to one
vote upon all matters to be acted upon at the Annual Meeting. For purposes of
voting at the Annual Meeting on all matters except the election of directors,
the Preferred Shares are treated as converted into Shares.

  Accordingly, on the record date there were issued and outstanding an
aggregate of (i) 42,109,262 Shares entitled to vote for the election of
directors, and (ii) 42,731,484 Shares, giving effect to the right to vote
622,222 Shares held by the holder of the 244,425 Preferred Shares, voting as
one class, entitled to vote on all other matters. A majority of the
outstanding Shares entitled to vote on any matter and represented at the
Annual Meeting in person or by proxy shall constitute a quorum. Assuming a
quorum is present, (i) the affirmative vote of a plurality of the 42,109,262
Shares so represented and entitled to vote is necessary to elect the directors
and (ii) the affirmative vote of a majority of the 42,731,484 Shares so
represented and entitled to vote, excluding broker non-votes, is necessary to
approve the amendment of the Company's 1995 Employee Stock Purchase Plan, as
amended, to approve the Company's 2000 Stock Option Plan and to approve the
appointment of PricewaterhouseCoopers LLP as the independent auditors of the
Company.

  Abstentions and broker non-votes are counted for purposes of determining the
presence or absence of a quorum for the transaction of business. If a
stockholder, present in person or by proxy, abstains on any matter, the
stockholder's Shares will not be voted on such matter. Thus, an abstention
from voting on any matter has the same legal effect as a vote "against" the
matter, even though the stockholder may interpret such action differently.
Except for determining the presence or absence of a quorum for the transaction
of business, broker non-votes are not counted for any purpose in determining
whether a matter has been approved.

    40,850 Shares subject to restricted stock awards granted to Dr. Cooper's
    wife, the Company's Vice President of Human Resources, as to which Dr.
    Cooper disclaims beneficial ownership. Amounts shown in this column were
    calculated based on the fair market value of Shares, as quoted by the
    Nasdaq Stock Market ("Nasdaq"), multiplied by the number of Shares subject
    to the restricted stock award: (i) for fiscal 1999, the fair market value
    of the Shares was $4.125, representing the closing price of the Shares on
    February 23, 1999; and (ii) for fiscal 1998, the fair market value of the
    Shares was $11.5625, representing the closing price of the Shares on
    November 7, 1997, except for 6,650 Shares subject to an award made to Dr.
    Cooper's wife on May 5, 1998, for which the fair market value was $6.02.

    The number of Shares subject to restricted stock awards granted to the
    named executive officers were as follows: (i) in fiscal 1999, 100,000
    Shares to Mr. Rogers; and (ii) in fiscal 1998, 225,000 Shares to Dr.
    Cooper and 150,000 Shares to each of Mr. Butler and Dr. Sandage. The
    Shares subject to the restricted stock awards may be sold immediately upon
    their vesting, which commenced in May 1998 for Drs. Cooper and Sandage and
    Mr. Butler and is scheduled to extend through January 2000, and which is
    subject to automatic extension during a Black-Out Period (as defined in
    the 1997 Plan). With respect to Mr. Rogers, initial vesting of his Shares
    subject to a restricted stock award was scheduled to commence in May 1999
    and extend through May 2000. In December 1999, the Board of Directors
    amended Mr. Rogers' restricted stock award by changing the vesting date
    for certain Shares from May 2000 to December 1999. Prior to their issuance
    upon vesting and satisfaction of any other required conditions, no
    dividends are payable with respect to the Shares subject to the restricted
    stock awards.

    In May 1998, a portion of the Shares subject to the restricted stock
    awards vested with respect to Drs. Cooper and Sandage and Mr. Butler and,
    upon payment representing the par value of the Shares, Shares were issued
    to the named executive officers as follows: 75,000 Shares to Dr. Cooper
    and 50,000 Shares to each of Mr. Butler and Dr. Sandage. The Shares were
    sold by such named executive officers immediately upon vesting. The value
    of the Shares issued at the May 1998 vesting, determined by the weighted
    average of the fair market value of the Shares sold in the aggregate by
    such named executive officers each day of vesting, multiplied by the
    number of Shares minus the amount of consideration paid, was as follows:
    $442,613 for Dr. Cooper (excluding $103,613 for Dr. Cooper's wife),
    $278,975 for Mr. Butler, and $283,300 for Dr. Sandage.

Restricted Stock Awards

  In fiscal 1998, the Company adopted the 1997 Plan, which covers an aggregate
of 1,750,000 Shares that have been and may be issued pursuant to restricted
stock awards upon satisfaction of specified vesting periods, in consideration
of services rendered to the Company, the par value of the Shares, or such
other consideration as the Board of Directors or the Compensation Committee of
the Board may determine. Pursuant to the 1997 Plan and his employment
agreement with the Company, the Company granted Mr. Rogers a restricted stock
award in February 1999 with respect to 100,000 Shares. Vesting of Mr. Rogers'
Shares under this award was scheduled to commence in May 1999 and extend
through May 2000. With respect to certain Shares originally scheduled to vest
in May 2000, the Board of Directors in December 1999 amended Mr. Rogers' award
to cause such Shares to vest in December 1999. Consideration to the Company
from Mr. Rogers consists of services to be rendered to the Company and payment
to the Company of the par value of the Shares. As a result of the 1997 Plan
provisions which defer vesting during Black-Out Periods (as defined in the
1997 Plan), no Shares of Mr. Rogers' award vested in fiscal 1999.

  The Shares issued and subject to the awards may be sold immediately upon
their vesting. The Company has a registration statement on Form S-8 relating
to the issuance of Shares under the 1997 Plan and the resale of the Shares
subject to awards granted to certain of the named executive officers.

the Company's prior employment agreement with Dr. Sandage, for Dr. Sandage to
continue to serve as the Company's Executive Vice President, Research and
Development and Chief Scientific Officer for a term of one year, subject to
automatic one year renewal periods, unless notice of termination is given by

<PAGE>

Dr. Sandage is entitled to receive his base salary plus pro-rated average

insurance during the term of Dr. Sandage's employment.

  In the event of certain transactions, including those which may result in a
Change in Control, as defined under each of the Company's 1989 Plan, 1994
Plan, 1997 Plan and 1998 Plan, unvested installments of options to purchase
Shares or awards of restricted stock held by executive officers of the Company
may be subject to accelerated vesting.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

  Section 16(a) of the 1934 Act requires the Company's executive officers and
directors and other persons who beneficially own more than 10% of a registered
class of the Company's equity securities to file with the S.E.C. initial
reports of ownership and reports of changes in ownership of common stock and
other equity securities of the Company. Such executive officers, directors,
and greater than 10% beneficial owners are required by S.E.C. regulation to
furnish the Company with copies of all Section 16(a) forms filed by such
reporting persons.

  Based solely on the Company's review of such forms furnished to the Company,
the Company believes that all filing requirements applicable to the Company's
executive officers, directors and greater than 10% beneficial owners were
complied with for fiscal 1999.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

  During fiscal 1999, the members of the Compensation Committee were: Mr.
Gray, General Haig, Dr. Morville and Mr. Sharrock. In fiscal 1999, none of the
members of the Compensation Committee was an officer or employee of the
Company or any of its subsidiaries. In fiscal 1999, the Company and its
subsidiaries paid or accrued to Mr. Sharrock, who also serves as a director of
Incara and served as a consultant to, and a director of, Progenitor: (i)
consulting fees for consulting services rendered by Mr. Sharrock to the
Company and to Progenitor of $28,000 and $2,000, respectively; (ii) $4,000 and
$2,000 in directors' fees from Incara and Progenitor, respectively; and (iii)
granted options to purchase 3,000 shares of common stock of Incara.

                         COMPENSATION COMMITTEE REPORT
                         ON EXECUTIVE COMPENSATION (1)

General

  The goal of the Company's executive compensation policy is to ensure that an
appropriate relationship exists between executive compensation and the
creation of stockholder value, while at the same time attracting, motivating
and retaining qualified executive officers. Accordingly, compensation
structures for the named executive officers of the Company generally include a
combination of salary, bonuses and long-term compensation. The Compensation
Committee's informal executive compensation philosophy (which applies
- --------
(1) The material in this report is not soliciting material, is not deemed
    filed with the S.E.C. and is not incorporated by reference in any filing
    of the Company under the 1933 Act or the 1934 Act, whether made before or
    after the date of this proxy statement and irrespective of any general
    incorporation language in such filing.

                                      15
<PAGE>

generally to all executive officers of the Company, including the President
and Chief Executive Officer, Glenn L. Cooper, M.D.) considers a number of
factors, which may include:

  .  providing compensation levels competitive with companies in comparable
     industries which are at a similar stage of development, or undergoing
     similar corporate events, and which are located in the Company's
     geographic area;

  .  identifying appropriate performance goals for the Company and providing
     flexibility in compensation levels with the achievement of such goals;

  .  rewarding above average corporate performance; and

  .  recognizing and providing incentive for individual initiative and
     achievement.

Base Salary

  Base salary for fiscal 1999 was determined based on a range of measures and
internal targets set before the start of the fiscal year and in part by
comparison to the compensation of executive officers of comparable
biotechnology and pharmaceutical companies.

Bonuses

  Bonus compensation for fiscal 1999 was contingent upon the Company achieving
certain business and financial objectives during the fiscal year. In
formulating the Senior Executive Bonus Plan for fiscal 1999 for executive
officers of the Company, including Dr. Cooper, the Compensation Committee
adopted performance measures tied to a number of business and financial
objectives to be achieved during fiscal 1999 and assigned relative weight to
each objective. The Senior Executive Bonus Plan for fiscal 1999 entitled the
named executive officers of the Company to a bonus equal to varying
percentages of base salary depending upon achieving these objectives which
included:

  .  achievement of certain defined clinical or regulatory product
     development milestones;

  .  out-licensing of certain compounds to a corporate development/marketing
     partner on terms approved by the Board of Directors;

  .  in-licensing or acquisition of a significant new asset;

  .  the fair market value of Shares relative to fiscal 1998 and specified
     indices;

  .  consummation of certain financial events; and

  .  consummation of an agreement that would substantially mitigate the
     Company's exposure to Redux-related product liability litigation.

  The Committee considered the Company's performance under these measures for
fiscal 1999 and used their subjective judgment and discretion, in accordance
with the parameters of the Senior Executive Bonus Plan for fiscal 1999, to
make a recommendation to the Board of Directors in approving individual
compensation. Under the terms of the Senior Executive Bonus Plan for fiscal
1999, the Board approved a bonus to Dr. Cooper of $70,000, and Messrs. Butler
and Rogers and Dr. Sandage each received bonuses of $45,050.

Glenn L. Cooper, M.D.

  The compensation received during fiscal 1999 by Dr. Cooper was governed in
part by the Cooper Agreement and his prior employment agreement with the
Company, and substantially in accordance with the policies described above
relating to all executive officers. In addition, in adopting the Senior
Executive Bonus Plan for fiscal 1999 and establishing the percentage of salary
used in calculating the bonus payment to Dr. Cooper, and recommending approval
of such bonus, members of the Compensation Committee also considered a
subjective evaluation of Dr. Cooper's performance and ability to influence the
Company's near and long-term growth. The Compensation Committee considered Dr.
Cooper's efforts and performance necessary to achieve specified objective
criteria, as described above. See "Employment Agreements."

Tax Deductibility of Compensation

  Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), limits the ability of the Company to deduct for tax purposes
compensation over $1,000,000 to any of the named executive officers unless, in
general, the compensation is paid pursuant to a plan which is performance
related, non-discretionary and has been approved by the Company's
stockholders. In fiscal 1999, the Company granted restricted stock awards
which, depending upon the fair market value of Shares on the date of vesting
of such awards, may result in compensation expense that may not be deductible
pursuant to Section 162(m) when recognized; however, no such limitation on
deductibility is applicable for fiscal 1999.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

  Dr. Rosenwald receives a management fee, which includes his out-of-pocket
expenses incurred in providing services to the Company of $2,500 per month
under a management agreement with the Company. For fiscal 1999, the Company
paid $30,000 to Dr. Rosenwald pursuant to this agreement.

  In fiscal 1999, the Company and its subsidiaries paid or accrued to Mr.
Sharrock, who also serves as a director of Incara and served as a consultant
to, and a director of, Progenitor: (i) consulting fees for consulting services
rendered by Mr. Sharrock to the Company and to Progenitor of $28,000 and
$2,000, respectively; (ii) $4,000 and $2,000 in directors' fees from Incara
and Progenitor, respectively; and (iii) granted options to purchase 3,000
shares of common stock of Incara.

  In fiscal 1999, Mr. Rogers received a restricted stock award under the 1997
Plan. In fiscal 1999, the Company also granted options to certain of the
Company's directors pursuant to automatic grant provisions under the 1994
Plan. In accordance with the terms of the 1994 Plan, on the date following the
Annual Meeting date, each of the directors of the Company (except Drs.
Rosenwald and Cooper) will receive automatic grants of options to purchase
5,000 Shares, which will be exercisable at a price equal to the fair market
value of the Company's Shares as determined on the date of grant. See
"Director Compensation."

                                PROPOSAL NO. 2:
   AMENDMENT OF THE COMPANY'S 1995 EMPLOYEE STOCK PURCHASE PLAN, AS AMENDED

  On February 3, 1995 the Board of Directors adopted the Company's 1995
Employee Stock Purchase Plan which was subsequently approved by Stockholders
on March 22, 1995 (the "1995 Plan"). A total of 100,000 Shares were reserved
for issuance under the 1995 Plan.

  On December 2, 1999, the Board of Directors authorized, subject to
stockholder approval, the amendment of the 1995 Plan (the "Amended 1995 Plan")
for the sole purpose of increasing the number of Shares reserved for issuance
thereunder from 100,000 Shares to 250,000 Shares. No other provision of the
1995 Plan was amended and all other provisions remain in full force and
effect.

  The Board of Directors believes that amending the 1995 Plan will benefit the
Company since providing employees of the Company with an opportunity to
purchase additional Shares of Common Stock should prove helpful in attracting,
retaining, and motivating valued employees.

  Through January 21, 2000, 73,352 Shares have been purchased under the 1995
Plan. Shares to be purchased pursuant to the Amended 1995 Plan are not
determinable.

THE BOARD OF DIRECTORS DEEMS PROPOSAL NO. 2 TO BE IN THE BEST INTERESTS OF THE
COMPANY AND THE STOCKHOLDERS AND RECOMMENDS A VOTE "FOR" THE APPROVAL THEREOF.

                              PROPOSAL NUMBER 3:
               APPROVAL OF THE COMPANY'S 2000 STOCK OPTION PLAN

General

  On January 19, 2000, the Board of Directors adopted the Company's 2000 Stock
Option Plan (the "2000 Plan"), pursuant to which employees, officers,
directors and consultants of the Company and any subsidiary corporations are
eligible to receive incentive stock options ("incentive options") within the
meaning of Section 422 of the Code, and options that do not qualify as
incentive options ("non-qualified options"). The 2000 Plan covers 2,500,000 of
the Company's Shares. The 2000 Plan, which expires in January 2010, is
administered by the Board of Directors or a committee of the Board of
Directors (the "Committee"). The purposes of the 2000 Plan are to attract,
motivate and insure the retention of key employees, and to provide additional
incentive by permitting such individuals to participate in the ownership of
the Company, and the criteria to be utilized by the Board of Directors or the
Committee in granting options pursuant to the 2000 Plan will be consistent
with these purposes.

Options

  Options granted under the 2000 Plan may be either incentive options or non-
qualified options. Incentive options granted under the 2000 Plan are
exercisable for a period of up to ten (10) years from the date of grant at an
exercise price which is not less than the fair market value of the Shares on
the date of the grant, except that the term of an incentive option granted
under the 2000 Plan to a stockholder owning more than 10% of the outstanding
voting power may not exceed five years and its exercise price may not be less
than 110% of the fair market value of the Shares on the date of the grant. To
the extent that the aggregate fair market value, as of the date of the grant,
of the Shares for which incentive options become exercisable for the first
time by an optionee during the calendar year exceeds $100,000, the portion of
such option which is in excess of the $100,000 limitation will be treated as a
non-qualified option. Additionally, the aggregate number of Shares that may be
subject to options granted to any person in a calendar year shall not exceed
50% of the maximum number of Shares which may be issued from time to time
under the 2000 Plan. Options granted under the 2000 Plan to employees of the
Company may be exercised only while the optionee is employed or retained by
the Company or within six months of the date of termination of the employment
relationship (three months in case of incentive options). However, options
which are exercisable at the time of termination by reason of death or
permanent disability of the optionee may be exercised within 12 months of the
date of termination of the employment relationship. Upon the exercise of an
option, payment may be made by cash or by any other means that the Board of
Directors or the Committee determines. No option may be granted under the 2000
Plan after January 2010.

  Options may be granted to such employees, officers, directors or consultants
of the Company or any subsidiary of the Company as the Board of Directors or
the Committee shall select from time to time in its sole discretion, provided
that only employees of the Company or a subsidiary of the Company shall be
eligible to receive incentive options.

  As of January 21, 2000, approximately 42 persons of the Company were
eligible to receive grants under the 2000 Plan. The number of future officers
and directors of the Company eligible to receive grants under the 2000 Plan is
not determinable. An optionee may be granted more than one option under the
2000 Plan. The Board of Directors or the Committee will, in its discretion,
determine (subject to the terms of the 2000 Plan) who will be granted options,
the time or times at which options shall be granted, and the number of Shares
subject to each option, whether the options are incentive options or non-
qualified options, and the manner in which options may be exercised. In making
such determination, consideration may be given to the value of the services
rendered by the respective individuals, their present and potential
contributions to the success of the Company and its subsidiaries and such
other factors deemed relevant in accomplishing the purpose of the 2000 Plan.

  Under the 2000 Plan, the optionee has none of the rights of a stockholder
with respect to the Shares issuable upon the exercise of the option until such
Shares shall be issued upon such exercise. No adjustment shall be

                                      20
<PAGE>

made for dividends or distributions or other rights for which the record date
is prior to the date of exercise, except as provided in the 2000 Plan. During
the lifetime of the optionee, an option shall be exercisable only by the
optionee. No option may be sold, pledged, assigned, hypothecated, transferred
or disposed of in any manner other than by will or by the laws of decent and
distribution, except that non-qualified options may be transferred by the
optionee during his lifetime to certain permitted transferees, subject to
certain conditions.

  The Board of Directors may amend or terminate the 2000 Plan except that
stockholder approval is required if required by Rule 16b-3 or Section 422 of
the Code. No action taken by the Board may materially and adversely affect any
outstanding option grant without the consent of the optionee.

Change in Control

  The 2000 Plan provides for acceleration of vesting in the event of certain
changes in control. Such acceleration may cause the consideration involved to
be treated in whole or in part as parachute payments under the Code.
Acceleration of benefits under other Company plans and other contracts with
employees in the event of such change of control could be subject to being
combined with the 2000 Plan accelerations for "parachute payment" purposes.
Any such "parachute payments" may be non-deductible to the Company in whole or
in part and the optionee may be subject to a 20% excise tax on all or part of
such payments (in addition to other taxes ordinarily payable).

Federal Income Tax Consequences

  Under current tax law, there are no Federal income tax consequences to
either the employee or the Company on the grant of non-qualified options if
granted under the terms set forth in the 2000 Plan. Upon exercise of a non-
qualified option, the excess of the fair market value of the Shares subject to
the option over the option price (the "Spread") at the date of exercise is
taxable as ordinary income to the optionee in the year it is exercised and is
generally deductible by the Company as compensation for Federal income tax
purposes. The optionee's basis in the Shares will be equal to the fair market
value on the date taxation is imposed and the holding period commences on such
date.

  Incentive option holders incur no regular Federal income tax liability at
the time of grant or upon exercise of such option, assuming that the optionee
was an employee of the Company from the date the option was granted until
three months before such exercise. However, upon exercise, the Spread must be
added to regular Federal taxable income in computing the optionee's
"alternative minimum tax" liability. An optionee's basis in the Shares
received on exercise of an incentive stock option will be the option price of
such Shares for regular income tax purposes. No deduction is allowable to the
Company for Federal income tax purposes in connection with the grant or
exercise of such option.

  If the holder of Shares acquired through exercise of an incentive option
sells such Shares within two years of the date of grant of such option or
within one year from the date of exercise of such option (a "Disqualifying
Disposition"), the optionee will realize income taxable at ordinary rates.
Ordinary income is reportable during the year of such sale equal to the
difference between the option price and the fair market value of the Shares at
the date the option is exercised, but the amount includable as ordinary income
shall not exceed the excess, if any, of the proceeds of such sale over the
option price. In addition to ordinary income, a Disqualifying Disposition may
result in taxable income subject to capital gains treatment if the sales
proceeds exceed the optionee's basis in the Shares (i.e., the option price
plus the amount includable as ordinary income). The amount of the optionee's
taxable ordinary income will generally be deductible by the Company in the
year of the Disqualifying Disposition.

  At the time of sale of Shares received upon exercise of an option (other
than a Disqualifying Disposition of Shares received upon the exercise of an
incentive option), any gain or loss is long-term or short-term capital gain or
loss, depending upon the holding period. If the Optionee disposes of Shares
received upon exercise of an option within 12 months of the Exercise date, the
Optionee recognizes short-term capital gain in the year of

                                      21
<PAGE>

disposition in an amount equal to the excess (if any) of the sales proceeds of
the Shares over the exercise price. If the Optionee disposes of Shares more
than 12 months after the Exercise Date, the Optionee will recognize capital
gains taxed at up to the maximum federal rate of 20%.

  The foregoing is not intended to be an exhaustive analysis of the tax
consequences relating to stock options issued under the 2000 Plan. For
instance, the treatment of options under state and local tax laws, which are
not described above, may differ from their treatment for Federal income tax
purposes.

Section 162(m) Limits on Deductibility

  Executive officers subject to Section 162(m) of the Code may receive options
under the 2000 Plan. Assuming stockholder approval of the 2000 Plan, the
Company believes the 2000 Plan should meet the requirements of Section 162(m).

  Future grants under the 2000 Plan have not yet been determined. The Company
intends to file a Registration Statement on Form S-8 relating to the issuance
of Shares under the 2000 Plan and the resale of the Shares subject to awards
granted to certain of the named executive officers.

  The Company also maintains the 1994 and 1998 Plans. As of December 31, 1999,
there were 1,525,220 Shares available for issuance under the 1994 Plan and
845,904 Shares available for issuance under the 1998 Plan.

  The affirmative vote of the holders of the majority of the Shares present in
person or by proxy at the Annual Meeting and entitled to vote on the matter is
required to approve and ratify the 2000 Plan. In the event stockholder
approval of the 2000 Plan is not obtained by January 19, 2001, no incentive
options may be granted under the 2000 Plan.

THE BOARD OF DIRECTORS DEEMS PROPOSAL NO. 3 TO BE IN THE BEST INTERESTS OF THE
COMPANY AND THE STOCKHOLDERS AND RECOMMENDS A VOTE "FOR" THE APPROVAL THEREOF.

                              PROPOSAL NUMBER 4:

                                    EXHIBIT

                       INTERNEURON PHARMACEUTICALS, INC.

                            2000 STOCK OPTION PLAN

1. Purpose.

  The purpose of this plan (the "Plan") is to secure for INTERNEURON
PHARMACEUTICALS, INC. (the "Company") and its stockholders the benefits
arising from capital stock ownership by employees, officers and directors of,
and consultants to, the Company who are expected to contribute to the
Company's future growth and success. Except where the context otherwise
requires, the term "Company" shall include all present and future subsidiaries
of the Company as defined in Sections 424(e) and 424(f) of the Internal
Revenue Code of 1986, as amended or replaced from time to time (the "Code").
Those provisions of the Plan which make express reference to Section 422 shall
apply only to Incentive Stock Options (as that term is defined in the Plan).

2. Type of Options and Administration.

  (a) Types of Options. Options granted pursuant to the Plan shall be
authorized by action of the Board of Directors of the Company (or a committee
designated by the Board of Directors, the "Committee") and may be either
incentive stock options ("Incentive Stock Options") meeting the requirements
of Section 422 of the Code or non-statutory options which are not intended to
meet the requirements of Section 422 of the Code.

  (b) Administration. The Plan will be administered by the Board of Directors
or the Committee, whose construction and interpretation of the terms and
provisions of the Plan shall be final and conclusive. The delegation of powers
to the Committee shall be consistent with applicable laws or regulations
(including, without limitation, applicable state law and Rule 16b-3 ("Rule
16b-3") promulgated under the Securities Exchange Act of 1934 (the "Exchange
Act"), or any successor rule). The Board of Directors or the Committee may in
its sole discretion grant options to purchase shares of the Company's Common
Stock, $.001 par value per share ("Common Stock") and issue shares upon
exercise of such options as provided in the Plan. The Board of Directors or
the Committee shall have authority, subject to the express provisions of the
Plan, to construe the respective option agreements and the Plan, to prescribe,
amend and rescind rules and regulations relating to the Plan, to determine the
terms and provisions of the respective option agreements, which need not be
identical, and to make all other determinations in the judgment of the Board
of Directors or the Committee necessary or desirable for the administration of
the Plan. The Board of Directors or the Committee may correct any defect or
supply any omission or reconcile any inconsistency in the Plan or in any
option agreement in the manner and to the extent it shall deem expedient to
carry the Plan into effect and it shall be the sole and final judge of such
expediency. No director or person acting pursuant to authority delegated by
the Board of Directors or the Committee shall be liable for any action or
determination under the Plan made in good faith. Subject to adjustment as
provided in Section 15 below, the aggregate number of shares of Common Stock
that may be subject to Options granted to any person in a calendar year shall
not exceed 50% of the maximum number of shares which may be issued and sold
under the Plan, as set forth in Section 4 hereof, as such section may be
amended from time to time.

  (c) Applicability of Rule 16b-3. Those provisions of the Plan which make
express reference to Rule 16b-3 shall apply to the Company only at such time
as the Company's Common Stock is registered under the Exchange Act, subject to
the last sentence of Section 3(b), and then only to such persons as are
required to file reports under Section 16(a) of the Exchange Act (a "Reporting
Person").

3. Eligibility.

  (a) Options may be granted to persons who are, at the time of grant,
employees, officers or directors of, and consultants to, the Company
("Participants") provided, that Incentive Stock Options may only be granted to
individuals who are employees of the Company (within the meaning of Section
3401(c) of the Code). A person

                                       1
<PAGE>

who has been granted an option may, if he or she is otherwise eligible, be
granted additional options if the Board of Directors or the Committee shall so
determine.

  (b) Grant of Options to Reporting Persons. The selection of a director or an
officer who is a Reporting Person (as the terms "director" and "officer" are
defined for purposes of Rule 16b-3) as a recipient of an option, the timing of
the option grant, the exercise price of the option and the number of shares
subject to the option shall be determined either by the Board of Directors by
the Committee.

4. Stock Subject to Plan.

  The stock subject to options granted under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. Subject to adjustment as
provided in Section 15 below, the maximum number of shares of Common Stock of
the Company which may be issued and sold under the Plan is two million five
hundred thousand (2,500,000) shares. If an option granted under the Plan shall
expire, terminate or is cancelled for any reason without having been exercised
in full, the unpurchased shares subject to such option shall again be
available for subsequent option grants under the Plan.

5. Forms of Option Agreements.

  As a condition to the grant of an option under the Plan, each recipient of
an option shall, if requested by the Company, execute an option agreement in
such form not inconsistent with the Plan as may be approved by the Board of
Directors or the Committee. Such option agreements may differ among
recipients.

6. Purchase Price.

  (a) General. The purchase price per share of stock deliverable upon the
exercise of an option shall be determined by the Board of Directors or the
Committee at the time of grant of such option; provided, however, that in the
case of an Incentive Stock Option, the exercise price shall not be less than
100% of the Fair Market Value (as hereinafter defined) of such stock, at the
time of grant of such option, or less than 110% of such Fair Market Value in
the case of options described in Section 11(b). "Fair Market Value" of a share
of Common Stock of the Company as of a specified date for the purposes of the
Plan shall mean the closing price of a share of the Common Stock on the
principal securities exchange (including the Nasdaq National Market) on which
such shares are traded on the day immediately preceding the date as of which
Fair Market Value is being determined, or on the next preceding date on which
such shares are traded if no shares were traded on such immediately preceding
day, or if the shares are not traded on a securities exchange, Fair Market
Value shall be deemed to be the average of the high bid and low asked prices
of the shares in the over-the-counter market on the day immediately preceding
the date as of which Fair Market Value is being determined or on the next
preceding date on which such high bid and low asked prices were recorded. If
the shares are not publicly traded, Fair Market Value of a share of Common
Stock (including, in the case of any repurchase of shares, any distributions
with respect thereto which would be repurchased with the shares) shall be
determined in good faith by the Board of Directors or the Committee. In no
case shall Fair Market Value be determined with regard to restrictions other
than restrictions which, by their terms, will never lapse.

  (b) Payment of Purchase Price. Options granted under the Plan may provide
for the payment of the exercise price by delivery of cash or a check to the
order of the Company in an amount equal to the exercise price of such options,
or by any other means which the Board of Directors or the Committee determines
are consistent with the purpose of the Plan and with applicable laws and
regulations (including, without limitation, the provisions of Rule 16b-3 and
Regulation T promulgated by the Federal Reserve Board).

7. Option Period.

  Subject to earlier termination as provided in the Plan, each option and all
rights thereunder shall expire on such date as determined by the Board of
Directors or the Committee and set forth in the applicable option agreement,
provided, that such date shall not be later than ten (10) years after the date
on which the option is granted.

                                       2
<PAGE>

8. Exercise of Options.

  Each option granted under the Plan shall be exercisable either in full or in
installments at such time or times and during such period as shall be set
forth in the option agreement evidencing such option, subject to the
provisions of the Plan. Subject to the requirements in the immediately
preceding sentence, if an option is not at the time of grant immediately
exercisable, the Board of Directors or the Committee may (i) in the agreement
evidencing such option, provide for the acceleration of the exercise date or
dates of the subject option upon the occurrence of specified events, and/or
(ii) at any time prior to the complete termination of an option, accelerate
the exercise date or dates of such option.

9. Transferability of Options.

  No incentive stock option granted under this Plan shall be assignable or
otherwise transferable by the optionee except by will or by the laws of
descent and distribution or pursuant to a qualified domestic relations order
as defined in the Code or Title I of the Employee Retirement Income Security
Act, or the rules thereunder. The Board of Directors or the Committee may, in
its discretion, authorize all or a portion of any non-statutory options to be
granted to an optionee to be on terms which permit transfer by such optionee
to (i) the spouse, children or grandchildren of the optionee ("Immediate
Family Members"), (ii) a trust or trusts for the exclusive benefit of such
Immediate Family Members, or (iii) a partnership in which such Immediate
Family Members are the only partners, provided that (w) the options must be
held by the optionee for a period of at least one month prior to transfer, (x)
there may be no consideration for any such transfer, (y) the stock option
agreement pursuant to which such options are granted must be approved by the
Board of Directors or the Committee, and must expressly provide for
transferability in a manner consistent with this Section, and (z) subsequent
transfers of transferred options shall be prohibited except by will or the
laws of descent and distribution or pursuant to a qualified domestic relations
order as defined in the Code or Title I of the Employee Retirement Income
Security Act, or the rules thereunder. Following transfer, any such options
shall continue to be subject to the same terms and conditions as were
applicable immediately prior to transfer, provided that for purposes of the
Plan the term "optionee" shall be deemed to refer to the transferee. The
events of termination of employment of Section 10 hereof shall continue to be
applied with respect to the original optionee. An option may be exercised
during the lifetime of the optionee only by the original optionee. In the
event an optionee dies during his employment by the Company or any of its
subsidiaries, or during the three-month period following the date of
termination of such employment, his option shall thereafter be exercisable,
during the period specified in the option agreement, by his executors or
administrators to the full extent to which such option was exercisable by the
optionee at the time of his death during the periods set forth in Section 10
or 11(d).

10. Effect of Termination of Employment or Other Relationship.

Except as provided in Section 11(d) with respect to Incentive Stock Options
and except as otherwise determined by the Committee at the date of grant of an
Option, and subject to the provisions of the Plan, an optionee may exercise an
option at any time within six (6) months following the termination of the
optionee's employment or other relationship with the Company or within one (1)
year if such termination was due to the death or disability of the optionee
but, except in the case of the optionee's death, in no event later than the
expiration date of the Option. If the termination of the optionee's employment
is for cause or is otherwise attributable to a breach by the optionee of an
employment or confidentiality or non-disclosure agreement, the option shall
expire immediately upon such termination. The Board of Directors shall have
the power to determine what constitutes a termination for cause or a breach of
an employment or confidentiality or non-disclosure agreement, whether an
optionee has been terminated for cause or has breached such an agreement, and
the date upon which such termination for cause or breach occurs. Any such
determinations shall be final and conclusive and binding upon the optionee.

11. Incentive Stock Options.

  Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:

    (a) Express Designation. All Incentive Stock Options granted under the
  Plan shall, at the time of grant, be specifically designated as such in the
  option agreement covering such Incentive Stock Options.

    (b) 10% Stockholder. If any employee to whom an Incentive Stock Option is
  to be granted under the Plan is, at the time of the grant of such option,
  the owner of stock possessing more than 10% of the total combined voting
  power of all classes of stock of the Company (after taking into account the
  attribution of stock ownership rules of Section 424(d) of the Code), then
  the following special provisions shall be applicable to the Incentive Stock
  Option granted to such individual:

      (i) The purchase price per share of the Common Stock subject to such
    Incentive Stock Option shall not be less than 110% of the Fair Market
    Value of one share of Common Stock at the time of grant; and

      (ii) The option exercise period shall not exceed five years from the
    date of grant.

    (c) Dollar Limitation. For so long as the Code shall so provide, options
  granted to any employee under the Plan (and any other incentive stock
  option plans of the Company) which are intended to constitute Incentive
  Stock Options shall not constitute Incentive Stock Options to the extent
  that such options, in the aggregate, become exercisable for the first time
  in any one calendar year for shares of Common Stock with an aggregate Fair
  Market Value, as of the respective date or dates of grant, of more than
  $100,000.

    (d) Termination of Employment, Death or Disability. No Incentive Stock
  Option may be exercised unless, at the time of such exercise, the optionee
  is, and has been continuously since the date of grant of his or her option,
  employed by the Company, except that:

      (i) an Incentive Stock Option may be exercised within the period of
    three months after the date the optionee ceases to be an employee of
    the Company (or within such lesser period as may be specified in the
    applicable option agreement), provided, that the agreement with respect
    to such option may designate a longer exercise period and that the
    exercise after such three-month period shall be treated as the exercise
    of a non-statutory option under the Plan;

      (ii) if the optionee dies while in the employ of the Company, or
    within three months after the optionee ceases to be such an employee,
    the Incentive Stock Option may be exercised by the person to whom it is
    transferred by will or the laws of descent and distribution within the
    period of one year after the date of death (or within such lesser
    period as may be specified in the applicable option agreement); and

      (iii) if the optionee becomes disabled (within the meaning of Section
    22(e)(3) of the Code or any successor provisions thereto) while in the
    employ of the Company, the Incentive Stock Option may be exercised
    within the period of one year after the date the optionee ceases to be
    such an employee because of such disability (or within such lesser
    period as may be specified in the applicable option agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of
the Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

12. Additional Provisions.

  (a) Additional Option Provisions. The Board of Directors or the Committee
may, in its sole discretion, include additional provisions in option
agreements covering options granted under the Plan, including without
limitation restrictions on transfer, repurchase rights, rights of first
refusal, commitments to pay cash bonuses, to make, arrange for or guaranty
loans or to transfer other property to optionees upon exercise of options, or
such other provisions as shall be determined by the Board of Directors or the
Committee; provided, that such

                                       4
<PAGE>

additional provisions shall not be inconsistent with any other term or
condition of the Plan and such additional provisions shall not cause any
Incentive Stock Option granted under the Plan to fail to qualify as an
Incentive Stock Option within the meaning of Section 422 of the Code.

  (b) Acceleration, Extension, Etc. The Board of Directors or the Committee
may, in its sole discretion, (i) accelerate the date or dates on which all or
any particular option or options granted under the Plan may be exercised or
(ii) extend the dates during which all, or any particular, option or options
granted under the Plan may be exercised; provided, however, that no such
extension shall be permitted if it would cause the Plan to fail to comply with
Section 422 of the Code or with Rule 16b-3 (if applicable).

13. General Restrictions.

  (a) Investment Representations. The Company may require any optionee, as a
condition of exercising such option, to give written assurances in substance
and form satisfactory to the Company to the effect that such person is
acquiring the Common Stock subject to the option or award, for his or her own
account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company
deems necessary or appropriate in order to comply with federal and applicable
state securities laws, or with covenants or representations made by the
Company in connection with any public offering of its Common Stock, including
any "lock-up" or other restriction on transferability.

  (b) Compliance With Securities Law. Each Option shall be subject to the
requirement that if, at any time, counsel to the Company shall determine that
the listing, registration or qualification of the shares subject to such
option or award upon any securities exchange or automated quotation system or
under any state or federal law, or the consent or approval of any governmental
or regulatory body, or that the disclosure of non-public information or the
satisfaction of any other condition is necessary as a condition of, or in
connection with the issuance of shares thereunder, such option may not be
exercised, in whole or in part, unless such listing, registration,
qualification, consent or approval, or satisfaction of such condition shall
have been effected or obtained on conditions acceptable to the Board of
Directors. Nothing herein shall be deemed to require the Company to apply for
or to obtain such listing, registration or qualification, or to satisfy such
condition.

14. Rights as a Stockholder.

  The holder of an option shall have no rights as a stockholder with respect
to any shares covered by the option (including, without limitation, any rights
to receive dividends or non-cash distributions with respect to such shares)
until the date of issue of a stock certificate to him or her for such shares.
No adjustment shall be made for dividends or other rights for which the record
date is prior to the date such stock certificate is issued.

15. Adjustment Provisions for Recapitalizations, Reorganizations and Related
Transactions.

  (a) Recapitalizations and Related Transactions. If, through or as a result
of any recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, (i) the outstanding shares
of Common Stock are increased, decreased or exchanged for a different number
or kind of shares or other securities of the Company, or (ii) additional
shares or new or different shares or other non-cash assets are distributed
with respect to such shares of Common Stock or other securities, an
appropriate and proportionate adjustment shall be made in (x) the maximum
number and kind of shares reserved for issuance under or otherwise referred to
in the Plan, (y) the number and kind of shares or other securities subject to
any then outstanding options under the Plan, and (z) the price for each share
subject to any then outstanding options under the Plan, without changing the
aggregate purchase price as to which such options remain exercisable.
Notwithstanding the foregoing, no adjustment shall be made pursuant to this
Section 15 if such adjustment (i) would cause the Plan to fail to comply with
Section 422 of the Code or with Rule 16b-3 or (ii) would be considered as the
adoption of a new plan requiring stockholder approval.

  (b) Reorganization, Merger and Related Transactions. All outstanding Options
under the Plan shall become fully exercisable for a period of sixty (60) days
following the occurrence of any Trigger Event, whether

                                       5
<PAGE>

or not such Options are then exercisable under the provisions of the
applicable agreements relating thereto. For purposes of the Plan, a "Trigger
Event" is any one of the following events:

    (i) the date on which shares of Common Stock are first purchased pursuant
  to a tender offer or exchange offer (other than such an offer by the
  Company, any Subsidiary, any employee benefit plan of the Company or of any
  Subsidiary or any entity holding shares or other securities of the Company
  for or pursuant to the terms of such plan), whether or not such offer is
  approved or opposed by the Company and regardless of the number of shares
  purchased pursuant to such offer;

    (ii) the date the Company acquires knowledge that any person or group
  deemed a person under Section 13(d)-3 of the Exchange Act (other than the
  Company, any Subsidiary, any employee benefit plan of the Company or of any
  Subsidiary or any entity holding shares of Common Stock or other securities
  of the Company for or pursuant to the terms of any such plan or any
  individual or entity or group or affiliate thereof which acquired its
  beneficial ownership interest prior to the date the Plan was adopted by the
  Board), in a transaction or series of transactions, has become the
  beneficial owner, directly or indirectly (with beneficial ownership
  determined as provided in Rule 13d-3, or any successor rule, under the
  Exchange Act), of securities of the Company entitling the person or group
  to 30% or more of all votes (without consideration of the rights of any
  class or stock to elect directors by a separate class vote) to which all
  shareholders of the Company would be entitled in the election of the Board
  of Directors were an election held on such date;

    (iii) the date, during any period of two consecutive years, when
  individuals who at the beginning of such period constitute the Board of
  Directors of the Company cease for any reason to constitute at least a
  majority thereof, unless the election, or the nomination for election by
  the stockholders of the Company, of each new director was approved by a
  vote of at least two-thirds of the directors then still in office who were
  directors at the beginning of such period; and

    (iv) the date of approval by the stockholders of the Company of an
  agreement (a "reorganization agreement") providing for:

      (A) The merger or consolidation of the Company with another
    corporation where the stockholders of the Company, immediately prior to
    the merger or consolidation, do not beneficially own, immediately after
    the merger or consolidation, shares of the corporation issuing cash or
    securities in the merger or consolidation entitling such stockholders
    to 65% or more of all votes (without consideration of the rights of any
    class of stock to elect directors by a separate class vote) to which
    all shareholders of such corporation would be entitled in the election
    of directors or where the members of the Board of Directors of the
    Company, immediately prior to the merger or consolidation, do not,
    immediately after the merger or consolidation, constitute a majority of
    the Board of Directors of the corporation issuing cash or securities in
    the merger or consolidation; or

      (B) The sale or other disposition of all or substantially all the
    assets of the Company.

  (c) Board Authority to Make Adjustments. Any adjustments under this Section
15 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive. No fractional shares will be issued under the Plan on
account of any such adjustments.

16. Merger, Consolidation, Asset Sale, Liquidation, etc.

  (a) General. In the event of a consolidation or merger or sale of all or
substantially all of the assets of the Company in which outstanding shares of
Common Stock are exchanged for securities, cash or other property of any other
corporation or business entity or in the event of a liquidation of the
Company, the Board of Directors of the Company, or the board of directors of
any corporation assuming the obligations of the Company, may, in its
discretion, take any one or more of the following actions, as to outstanding
options: (i) in the event of a merger under the terms of which holders of the
Common Stock of the Company will receive upon consummation thereof a cash
payment for each share surrendered in the merger (the "Merger Price"), make or
provide for a cash

                                       6
<PAGE>

payment to the optionees equal to the difference between (A) the Merger Price
times the number of shares of Common Stock subject to such outstanding options
(to the extent then exercisable at prices not in excess of the Merger Price)
and (B) the aggregate exercise price of all such outstanding options in
exchange for the termination of such options, and (ii) in the event the
provisions of Section 15 are not applicable, provide that all or any
outstanding options shall become exercisable in full immediately prior to such
event; provided, however, nothing contained in this Section 16 shall permit
any change in the accelerated vesting pursuant to Section 15 upon the
occurrence of a Trigger Event.

  (b) Substitute Options. The Company may grant options under the Plan in
substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company,
or one of its subsidiaries, of property or stock of the employing corporation.
The Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the
circumstances.

17. No Special Employment Rights.

  Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment
by the Company or interfere in any way with the right of the Company at any
time to terminate such employment or to increase or decrease the compensation
of the optionee.

18. Other Employee Benefits.

  Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares
received upon such exercise will not constitute compensation with respect to
which any other employee benefits of such employee are determined, including,
without limitation, benefits under any bonus, pension, profit-sharing, life
insurance or salary continuation plan, except as otherwise specifically
determined by the Board of Directors.

19. Amendment of the Plan.

  (a) The Board of Directors may at any time, and from time to time, modify or
amend the Plan in any respect; provided, however, that if at any time the
approval of the stockholders of the Company is required under Section 422 of
the Code or any successor provision with respect to Incentive Stock Options,
or under Rule 16b-3, the Board of Directors may not effect such modification
or amendment without such approval; and provided, further, that the provisions
of Section 3(b) hereof shall not be amended more than once every six months,
other than to comport with changes in the Code, the Employer Retirement Income
Security Act of 1974, as amended, or the rules thereunder.

  (b) The modification or amendment of the Plan shall not, without the consent
of an optionee, adversely affect his or her rights under an option previously
granted to him or her. With the consent of the optionee affected, the Board of
Directors may amend outstanding option agreements in a manner not inconsistent
with the Plan. The Board of Directors shall have the right to amend or modify
(i) the terms and provisions of the Plan and of any outstanding Incentive
Stock Options granted under the Plan to the extent necessary to qualify any or
all such options for such favorable federal income tax treatment (including
deferral of taxation upon exercise) as may be afforded incentive stock options
under Section 422 of the Code and (ii) the terms and provisions of the Plan
and of any outstanding option to the extent necessary to ensure the
qualification of the Plan under Rule 16b-3.

20. Withholding.

  (a) The Company shall have the right to deduct from payments of any kind
otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan. Subject to the prior approval of the Company, which
may be withheld

                                       7
<PAGE>

by the Company in its sole discretion, the optionee may elect to satisfy such
obligations, in whole or in part, (i) by causing the Company to withhold
shares of Common Stock otherwise issuable pursuant to the exercise of an
option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee. The shares so delivered or withheld shall have a Fair
Market Value equal to such withholding obligation as of the date that the
amount of tax to be withheld is to be determined. An optionee who has made an
election pursuant to this Section 20(a) may only satisfy his or her
withholding obligation with shares of Common Stock which are not subject to
any repurchase, forfeiture, unfulfilled vesting or other similar requirements.

  (b) The acceptance of shares of Common Stock upon exercise of an Incentive
Stock Option shall constitute an agreement by the optionee (i) to notify the
Company if any or all of such shares are disposed of by the optionee within
two years from the date the option was granted or within one year from the
date the shares were issued to the optionee pursuant to the exercise of the
option, and (ii) if required by law, to remit to the Company, at the time of
and in the case of any such disposition, an amount sufficient to satisfy the
Company's federal, state and local withholding tax obligations with respect to
such disposition, whether or not, as to both (i) and (ii), the optionee is in
the employ of the Company at the time of such disposition.

  (c) Notwithstanding the foregoing, in the case of a Reporting Person whose
options have been granted in accordance with the provisions of Section 3(b)
herein, no election to use shares for the payment of withholding taxes shall
be effective unless made in compliance with any applicable requirements of
Rule 16b-3.

21. Effective Date and Duration of the Plan.

  (a) Effective Date. The Plan shall become effective when adopted by the
Board of Directors, but no Incentive Stock Option granted under the Plan shall
become exercisable unless and until the Plan shall have been approved by the
Company's stockholders. If such stockholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no options
previously granted under the Plan shall be deemed to be Incentive Stock
Options and no Incentive Stock Options shall be granted thereafter. Amendments
to the Plan not requiring stockholder approval shall become effective when
adopted by the Board of Directors; amendments requiring stockholder approval
(as provided in Section 19) shall become effective when adopted by the Board
of Directors, but no Incentive Stock Option granted after the date of such
amendment shall become exercisable (to the extent that such amendment to the
Plan was required to enable the Company to grant such Incentive Stock Option
to a particular optionee) unless and until such amendment shall have been
approved by the Company's stockholders. If such stockholder approval is not
obtained within twelve months of the Board's adoption of such amendment, any
Incentive Stock Options granted on or after the date of such amendment shall
terminate to the extent that such amendment to the Plan was required to enable
the Company to grant such option to a particular optionee. Subject to this
limitation, options may be granted under the Plan at any time after the
effective date and before the date fixed for termination of the Plan.

  (b) Termination. Unless sooner terminated in accordance with Section 16, the
Plan shall terminate upon the earlier of (i) the close of business on the day
next preceding the tenth anniversary of the date of its adoption by the Board
of Directors, or (ii) the date on which all shares available for issuance
under the Plan shall have been issued pursuant to the exercise or cancellation
of options granted under the Plan. If the date of termination is determined
under (i) above, then options outstanding on such date shall continue to have
force and effect in accordance with the provisions of the instruments
evidencing such options.

22. Provision for Foreign Participants.

  The Board of Directors may, without amending the Plan, modify awards or
options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities,
currency, employee benefit or other matters.


                                       8

23. Governing Law.

  The provisions of this Plan shall be governed and construed in accordance
with the laws of the State of Delaware without regard to the principles of
conflicts of laws.

  Adopted by the Board of Directors on January 19, 2000.
