                   UNITY EMERGING TECHNOLOGY VENTURE ONE LTD.

                             2000 STOCK OPTION PLAN

      1. PURPOSE. The purpose of the Unity Emerging Technology Venture One Ltd.
2000 Stock Option Plan (the "Plan") is to encourage key employees of Unity
Emerging Technology Venture One Ltd. (the "Company") and of any present or
future parent or subsidiary of the Company (collectively, "Related
Corporations") and other individuals who render services to the Company or a
Related Corporation, by providing opportunities to participate in the ownership
of the Company and its future growth through (a) the grant of options which
qualify as "incentive stock options" ("ISOs") under Section 422(b) of the
Internal Revenue Code of 1986, as amended (the "Code"); and (b) the grant of
options which do not qualify as ISOs ("Non-Qualified Options"). Both ISOs and
Non-Qualified Options are referred to hereafter individually as an "Option" and
collectively as "Options." As used herein, the terms "parent" and "subsidiary"
mean "parent corporation" and "subsidiary corporation," respectively, as those
terms are defined in Section 424 of the Code.

      2. ADMINISTRATION OF THE PLAN.

            (a) BOARD OR COMMITTEE ADMINISTRATION. The Plan shall be
administered by the Board of Directors of the Company (the "Board") or by a
committee appointed by the Board (the "Committee"); provided that the Plan shall
be administered: (i) to the extent required by applicable regulations under
Section 162(m) of the Code, by two or more "outside directors" (as defined in
applicable regulations thereunder) and (ii) to the extent required by Rule 16b-3
promulgated under the Securities Exchange Act of 1934, as amended, or any
successor provision ("Rule 16b-3"), by a disinterested administrator or
administrators within the meaning of Rule 16b-3. All references in this Plan to
the "Committee" shall mean the Board if no Committee has been appointed. Subject
to ratification of the grant or authorization of each Option by the Board (if so
required by applicable state law), and subject to the terms of the Plan, the
Committee shall have the authority to (i) determine to whom (from among the
class of employees eligible under paragraph 3 to receive ISOs) ISOs shall be
granted, and to whom (from among the class of individuals and entities eligible
under paragraph 3 to receive Non-Qualified Options) Non-Qualified Options may be
granted; (ii) determine the time or times at which Options shall be granted;
(iii) determine the purchase price of shares subject to each Option, which
prices shall not be less than the minimum price specified in paragraph 6; (iv)
determine whether each Option granted shall be an ISO or a Non-Qualified Option;
(v) determine (subject to paragraph 7) the time or times when each Option shall
become exercisable and the duration of the exercise period; (vi) extend the
period during which outstanding Options may


<PAGE>

be exercised; (vii) determine whether restrictions are to be imposed on shares
subject to Options and the nature of such restrictions, if any, and (viii)
interpret the Plan and prescribe and rescind rules and regulations relating to
it. If the Committee determines to issue a Non-Qualified Option, it shall take
whatever actions it deems necessary, under Section 422 of the Code and the
regulations promulgated thereunder, to ensure that such Option is not treated as
an ISO. The interpretation and construction by the Committee of any provisions
of the Plan or of any Option granted under it shall be final unless otherwise
determined by the Board. The Committee may from time to time adopt such rules
and regulations for carrying out the Plan as it may deem advisable. No member of
the Board or the Committee shall be liable for any action or determination made
in good faith with respect to the Plan or any Option granted under it.

            (b) COMMITTEE ACTIONS. The Committee may select one of its members
as its chairman, and shall hold meetings at such time and places as it may
determine. A majority of the Committee shall constitute a quorum and acts of a
majority of the members of the Committee at a meeting at which a quorum is
present, or acts reduced to or approved in writing by all the members of the
Committee (if consistent with applicable state law), shall be the valid acts of
the Committee. From time to time the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or
without cause) and appoint new members in substitution therefor, fill vacancies
however caused, or remove all members of the Committee and thereafter directly
administer the Plan.

            (c) GRANT OF OPTIONS TO BOARD MEMBERS. Subject to the provisions of
the first sentence of paragraph 2(a) above, if applicable, Options may be
granted to members of the Board. All grants of Options to members of the Board
shall in all other respects be made in accordance with the provisions of this
Plan applicable to other eligible persons. Consistent with the provisions of the
first sentence of Paragraph 2(a) above, members of the Board who either (i) are
eligible to receive grants of Options pursuant to the Plan or (ii) have been
granted Options may vote on any matters affecting the administration of the Plan
or the grant of any Options pursuant to the Plan, except that no such member
shall act upon the granting to himself or herself of Options, but any such
member may be counted in determining the existence of a quorum at any meeting of
the Board during which action is taken with respect to the granting to such
member of Options.

            (d) EXCULPATION. No member of the Board shall be personally liable
for monetary damages for any action taken or any failure to take any action in
connection with the administration of the Plan or the granting of Options under
the Plan, provided that


                                      2

<PAGE>

this subparagraph 3(c) shall apply to (i) any breach of such member's duty of
loyalty to the Company or its stockholders, (ii) acts or omissions not in good
faith or involving intentional misconduct or a knowing violation of law, (iii)
acts or omissions that would result in liability under Section 174 of the
General Corporation Law of the State of Delaware, as amended, and (iv) any
transaction from which the member derived an improper personal benefit.

            (e) INDEMNIFICATION. Service on the Committee shall constitute
service as a member of the Board. Each member of the Committee shall be entitled
without further act on his or her part to indemnity from the Company to the
fullest extent provided by applicable law and the Company's Certificate of
Incorporation and/or By-laws in connection with or arising out of any action,
suit or proceeding with respect to the administration of the Plan or the
granting of Options thereunder in which he or she may be involved by reason of
his or her being or having been a member of the Committee, whether or not he or
she continues to be a member of the Committee at the time of the action, suit or
proceeding.

      3. ELIGIBLE EMPLOYEES AND OTHERS. ISOs may be granted only to employees of
the Company or any Related Corporation. Non-Qualified Options may be granted to
any employee, officer or director (whether or not also an employee) or
consultant of the Company or any Related Corporation. The Committee may take
into consideration a recipient's individual circumstances in determining whether
to grant an Option. The granting of any Option to any individual or entity shall
neither entitle that individual or entity to, nor disqualify such individual or
entity from, participation in any other grant of Options.

      4. STOCK. The stock subject to Options shall be authorized but unissued
shares of Common Stock of the Company, par value $.0001 per share (the "Common
Stock"), or shares of Common Stock reacquired by the Company in any manner. The
aggregate number of shares which may be issued pursuant to the Plan is 255,000,
subject to adjustment as provided in paragraph 13. If any Option granted under
the Plan shall expire or terminate for any reason without having been exercised
in full or shall cease for any reason to be exercisable in whole or in part, the
shares of Common Stock subject to such Option shall again be available for
grants of Options under the Plan.

      5. GRANTING OF OPTIONS. Options may be granted under the Plan at any time
on or after March 17, 2000 and prior to March 17, 2010. The date of grant of an
Option under the Plan will be the date specified by the Committee at the time it
grants the Option; provided, however, that such date shall not be prior to the
date on


                                      3

<PAGE>

which the Committee acts to approve the grant. Options granted under the Plan
are intended to qualify as performance based compensation to the extent required
under proposed Treasury Regulation Section 1.162-27.

      6. MINIMUM OPTION PRICE; ISO LIMITATIONS.

            (a) PRICE FOR NON-QUALIFIED OPTIONS. The exercise price per share
specified in the agreement relating to each Non-Qualified Option granted under
the Plan shall in no event be less than the minimum legal consideration required
therefor under the laws of any jurisdiction in which the Company or its
successors in interest may be organized. Non-Qualified Options granted under the
Plan, with an exercise price less than the fair market value per share of Common
Stock on the date of grant, are intended to qualify as performance based
compensation under Section 162(m) of the Code and any applicable regulations
thereunder. Any such Non-Qualified Options granted under the Plan shall be
exercisable only upon the attainment of a preestablished, objective performance
goal established by the Committee.

            (b) PRICE FOR ISOS. The exercise price per share specified in the
agreement relating to each ISO granted under the Plan shall not be less than the
fair market value per share of Common Stock on the date of such grant. In the
case of an ISO to be granted to an employee owning stock possessing more than
ten percent (10%) of the total combined voting power of all classes of stock of
the Company or any Related Corporation, the price per share specified in the
agreement relating to such ISO shall not be less than one hundred ten percent
(110%) of the fair market value per share of Common Stock on the date of grant.
For purposes of determining stock ownership under this paragraph, the rules of
Section 424(d) of the Code shall apply.

            (c) $100,000 ANNUAL LIMITATION ON ISO VESTING. Each eligible
employee may be granted Options treated as ISOs only to the extent that, in the
aggregate under this Plan and all incentive stock option plans of the Company
and any Related Corporation, ISOs do not become exercisable for the first time
by such employee during any calendar year with respect to stock having a fair
market value (determined at the time the ISOs were granted) in excess of
$100,000. The Company intends to designate any Options granted in excess of such
limitation as Non-Qualified Options.

            (d) DETERMINATION OF FAIR MARKET VALUE. If, at the time an Option is
granted under the Plan, the Company's Common Stock is publicly traded, "fair
market value" shall be determined as of the date of grant or, if the prices or
quotes discussed in this sentence are unavailable for such date, the last
business day for which such prices or quotes are available prior to the date of


                                      4

<PAGE>

grant and shall mean (i) the average (on that date) of the high and low prices
of the Common Stock on the principal national securities exchange on which the
Common Stock is traded, if the Common Stock is then traded on a national
securities exchange; or (ii) the last reported sale price (on that date) of the
Common Stock on the Nasdaq National Market, if the Common Stock is not then
traded on a national securities exchange; or (iii) the closing bid price (or
average of bid prices) last quoted (on that date) by an established quotation
service for over-the-counter securities, if the Common Stock is not reported on
the Nasdaq National Market. If the Common Stock is not publicly traded at the
time an Option is granted under the Plan, "fair market value" shall mean the
fair value of the Common Stock as determined by the Committee after taking into
consideration all factors which it deems appropriate, including, without
limitation, recent sale and offer prices of the Common Stock in private
transactions negotiated at arm's length.

      7. OPTION DURATION. Subject to earlier termination as provided in
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than (i) ten
years from the date of grant in the case of Options generally and (ii) five
years from the date of grant in the case of ISOs granted to an employee owning
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Related Corporation, as determined
under paragraph 6(b). Subject to earlier termination as provided in paragraphs 9
and 10, the term of each ISO shall be the term set forth in the original
instrument granting such ISO, except with respect to any part of such ISO that
is converted into a Non-Qualified Option pursuant to paragraph 16.

      8. EXERCISE OF OPTION. Subject to the provisions of paragraphs 9 through
12, each Option granted under the Plan shall be exercisable as follows:

            (a) VESTING. The Option shall either be fully exercisable on the
date of grant or shall become exercisable thereafter in such installments as the
Committee may specify.

            (b) FULL VESTING OF INSTALLMENTS. Once an installment becomes
exercisable, it shall remain exercisable until expiration or termination of the
Option, unless otherwise specified by the Committee.

            (c) PARTIAL EXERCISE. Each Option or installment may be exercised at
any time or from time to time, in whole or in part, for up to the total number
of shares with respect to which it is then exercisable.


                                      5

<PAGE>

            (d) ACCELERATION OF VESTING. The Committee shall have the right to
accelerate the date that any installment of any Option becomes exercisable;
provided that the Committee shall not, without the consent of an optionee,
accelerate the permitted exercise date of any installment of any Option granted
to any employee as an ISO (and not previously converted into a Non-Qualified
Option pursuant to paragraph 16) if such acceleration would violate the annual
vesting limitation contained in Section 422(d) of the Code, as described in
paragraph 6(c).

      9. TERMINATION OF EMPLOYMENT. Unless otherwise specified in the agreement
relating to such ISO, if an ISO optionee ceases to be employed by the Company
and all Related Corporations other than by reason of death or disability or as
otherwise specified in paragraph 10, no further installments of his or her ISOs
shall become exercisable, and his or her ISOs shall terminate on the earlier of
(a) ninety (90) days after the date of termination of his or her employment, or
(b) their specified expiration dates, except to the extent that such ISOs (or
unexercised installments thereof) have been converted into Non-Qualified Options
pursuant to paragraph 16. For purposes of this paragraph 9, employment shall be
considered as continuing uninterrupted during any BONA FIDE leave of absence
(such as those attributable to illness, military obligations or governmental
service) provided that the period of such leave does not exceed 90 days or, if
longer, any period during which such optionee's right to reemployment is
guaranteed by statute. A BONA FIDE leave of absence with the written approval of
the Committee shall not be considered an interruption of employment under this
paragraph 9, provided that such written approval contractually obligates the
Company or any Related Corporation to continue the employment of the optionee
after the approved period of absence. ISOs granted under the Plan shall not be
affected by any change of employment within or among the Company and Related
Corporations, so long as the optionee continues to be an employee of the Company
or any Related Corporation. Nothing in the Plan shall be deemed to give any
grantee of any Option the right to be retained in employment or other service by
the Company or any Related Corporation for any period of time.

      10. DEATH; DISABILITY; BREACH.

            (a) DEATH. If an ISO optionee ceases to be employed by the Company
and all Related Corporations by reason of his or her death, any ISO owned by
such optionee may be exercised, to the extent otherwise exercisable on the date
of death, by the estate, personal representative or beneficiary who has acquired
the ISO by will or by the laws of descent and distribution, until the earlier of
(i) the specified expiration date of the ISO or (ii) one (1) year from the date
of the optionee's death.


                                      6

<PAGE>

            (b) DISABILITY. If an ISO optionee ceases to be employed by the
Company and all Related Corporations by reason of his or her disability, such
optionee shall have the right to exercise any ISO held by him or her on the date
of termination of employment, for the number of shares for which he or she could
have exercised it on that date, until the earlier of (i) the specified
expiration date of the ISO or (ii) one (1) year from the date of the termination
of the optionee's employment. For the purposes of the Plan, the term
"disability" shall mean "permanent and total disability" as defined in Section
22(e)(3) of the Code or any successor statute.

            (c) BREACH. If an ISO optionee ceases to be employed by the Company
and all Related Corporation by reason of a finding by the Committee, after full
consideration of the facts presented on behalf of both the Company and the
Optionee, that the ISO optionee has breached his or her employment or service
contract with the Company or any Related Corporation, or has been engaged in
disloyalty to the Company or any Related Corporation, then, in such event, in
addition to immediate termination of the Option, the ISO optionee shall
automatically forfeit all shares for which the Company has not yet delivered
share certificates upon refund by the Company of the exercise price of such
Option. Notwithstanding anything herein to the contrary, the Company may
withhold delivery of share certificates pending the resolution of any inquiry
that could lead to a finding resulting in a forfeiture.

      11. ASSIGNABILITY. No Option shall be assignable or transferable by the
grantee except by will, by the laws of descent and distribution or, in the case
of Non-Qualified Options only, pursuant to a valid domestic relations order.
Except as set forth in the previous sentence, during the lifetime of a grantee
each Option shall be exercisable only by such grantee.

      12. TERMS AND CONDITIONS OF OPTIONS. Options shall be evidenced by
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. The Committee may specify that any
Non-Qualified Option shall be subject to the restrictions set forth herein with
respect to ISOs, or to such other termination and cancellation provisions as the
Committee may determine. The Committee may from time to time confer authority
and responsibility on one or more of its own members and/or one or more officers
of the Company to execute and deliver such instruments. The proper officers of
the Company are authorized and directed to take any and all action necessary or
advisable from


                                      7

<PAGE>

time to time to carry out the terms of such instruments.

      13. ADJUSTMENTS. Upon the occurrence of any of the following events, an
optionee's rights with respect to Options granted to such optionee hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between the optionee and the Company relating
to such Option:

            (a) STOCK DIVIDENDS AND STOCK SPLITS. If the shares of Common Stock
shall be subdivided or combined into a greater or smaller number of shares or if
the Company shall issue any shares of Common Stock as a stock dividend on its
outstanding Common Stock, the number of shares of Common Stock deliverable upon
the exercise of Options shall be appropriately increased or decreased
proportionately, and appropriate adjustments shall be made in the purchase price
per share to reflect such subdivision, combination or stock dividend.

            (b) CONSOLIDATIONS OR MERGERS. If the Company is to be consolidated
with or acquired by another entity in a merger, sale of all or substantially all
of the Company's assets or otherwise (an "Acquisition"), the Committee or the
board of directors of any entity assuming the obligations of the Company
hereunder (the "Successor Board"), shall, as to outstanding Options, either (i)
make appropriate provision for the continuation of such Options by substituting
on an equitable basis for the shares then subject to such Options either (A) the
consideration payable with respect to the outstanding shares of Common Stock in
connection with the Acquisition, (B) shares of stock of the surviving
corporation or (C) such other securities as the Successor Board deems
appropriate, the fair market value of which shall approximate the fair market
value of the shares of Common Stock subject to such Options immediately
preceding the Acquisition; or (ii) upon written notice to the optionees, provide
that all Options must be exercised, to the extent then exercisable, within a
specified number of days of the date of such notice, at the end of which period
the Options shall terminate; or (iii) terminate all Options in exchange for a
cash payment equal to the excess of the fair market value of the shares subject
to such Options (to the extent then exercisable) over the exercise price
thereof.

            (c) RECAPITALIZATION OR REORGANIZATION. In the event of a
recapitalization or reorganization of the Company (other than a transaction
described in subparagraph (c) above) pursuant to which securities of the Company
or of another corporation are issued with respect to the outstanding shares of
Common Stock, an optionee upon exercising an Option shall be entitled to receive
for the purchase price paid upon such exercise the securities he or she would
have received if he or she had exercised such Option prior to such
recapitalization or reorganization.


                                      8

<PAGE>

            (d) MODIFICATION OF ISOS. Notwithstanding the foregoing, any
adjustments made pursuant to subparagraphs (a), (b) or (c) with respect to ISOs
shall be made only after the Committee, after consulting with counsel for the
Company, determines whether such adjustments would constitute a "modification"
of such ISOs (as that term is defined in Section 424 of the Code) or would cause
any adverse tax consequences for the holders of such ISOs. If the Committee
determines that such adjustments made with respect to ISOs would constitute a
modification of such ISOs or would cause adverse tax consequences to the
holders, it may refrain from making such adjustments.

            (e) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, each Option will terminate
immediately prior to the consummation of such proposed action or at such other
time and subject to such other conditions as shall be determined by the
Committee.

            (f) ISSUANCES OF SECURITIES. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
subject to Options. No adjustments shall be made for dividends paid in cash or
in property other than securities of the Company.

            (g) FRACTIONAL SHARES. No fractional shares shall be issued under
the Plan and the optionee shall receive from the Company cash in lieu of such
fractional shares.

            (h) ADJUSTMENTS. Upon the happening of any of the events described
in subparagraphs (a), (b) or (c) above, the class and aggregate number of shares
set forth in paragraph 4 hereof that are subject to Options which previously
have been or subsequently may be granted under the Plan shall also be
appropriately adjusted to reflect the events described in such subparagraphs.
The Committee or the Successor Board shall determine the specific adjustments to
be made under this paragraph 13 and, subject to paragraph 2, its determination
shall be conclusive.

      14. MEANS OF EXERCISING OPTIONS. An Option (or any part or installment
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, accompanied by full
payment of the purchase price therefor either (a) in United States dollars in
cash or by check, (b) at the discretion of the Committee, through delivery of
shares of Common Stock having a fair market value equal as of the date of the
exercise to the cash exercise


                                      9

<PAGE>

price of the Option, (c) at the discretion of the Committee, by delivery of the
grantee's personal recourse note bearing interest payable not less than annually
at no less than 100% of the lowest applicable Federal rate, as defined in
Section 1274(d) of the Code, (d) at the discretion of the Committee and
consistent with applicable law, through the delivery of an assignment to the
Company of a sufficient amount of the proceeds from the sale of the Common Stock
acquired upon exercise of the Option and an authorization to the broker or
selling agent to pay that amount to the Company, which sale shall be at the
participant's direction at the time of exercise, or (e) at the discretion of the
Committee, by any combination of (a), (b), (c) and (d) above. If the Committee
exercises its discretion to permit payment of the exercise price of an ISO by
means of the methods set forth in clauses (b), (c), (d) or (e) of the preceding
sentence, such discretion shall be exercised in writing at the time of the grant
of the ISO in question. The holder of an Option shall not have the rights of a
shareholder with respect to the shares covered by such Option until the date of
issuance of a stock certificate to such holder for such shares. Except as
expressly provided above in paragraph 13 with respect to changes in
capitalization and stock dividends, no adjustment shall be made for dividends or
similar rights for which the record date is before the date such stock
certificate is issued.

      15. TERM AND AMENDMENT OF PLAN. This Plan was adopted by the Board on
March 17, 2000, subject, with respect to the validation of ISOs granted under
the Plan, to approval of the Plan by the stockholders of the Company at the next
Meeting of Stockholders or, in lieu thereof, by written consent. If the approval
of stockholders is not obtained on or prior to March 17, 2010, any grants of
ISOs under the Plan made prior to that date will be rescinded. The Plan shall
expire at the end of the day on May 30, 2006 (except as to Options outstanding
on that date). Subject to the provisions of paragraph 5 above, Options may be
granted under the Plan prior to the date of stockholder approval of the Plan.
The Board may terminate or amend the Plan in any respect at any time, except
that, without the approval of the stockholders obtained within 12 months before
or after the Board adopts a resolution authorizing any of the following actions:
(a) the total number of shares that may be issued under the Plan may not be
increased (except by adjustment pursuant to paragraph 13); (b) the benefits
accruing to participants under the Plan may not be materially increased; (c) the
requirements as to eligibility for participation in the Plan may not be
materially modified; (d) the provisions of paragraph 3 regarding eligibility for
grants of ISOs may not be modified; (e) the provisions of paragraph 6(b)
regarding the exercise price at which shares may be offered pursuant to ISOs may
not be modified (except by adjustment pursuant to paragraph 13); (f) the
expiration date of the Plan may not be extended; and (g)


                                      10

<PAGE>

the Board may not take any action which would cause the Plan to fail to comply
with Rule 16b-3. Except as otherwise provided in this paragraph 15, in no event
may action of the Board or stockholders alter or impair the rights of a grantee,
without such grantee's consent, under any Option previously granted to such
grantee.

      16. APPLICATION OF FUNDS. The proceeds received by the Company from the
sale of shares pursuant to Options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

      17. NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION. By accepting an ISO
granted under the Plan, each optionee agrees to notify the Company in writing
immediately after such optionee makes a Disqualifying Disposition (as described
in Sections 421, 422 and 424 of the Code and regulations thereunder) of any
stock acquired pursuant to the exercise of ISOs granted under the Plan. A
Disqualifying Disposition is generally any disposition occurring on or before
the later of (a) the date two years following the date the ISO was granted or
(b) the date one year following the date the ISO was exercised.

      18. WITHHOLDING OF ADDITIONAL INCOME TAXES. Upon the exercise of a
Non-Qualified Option, the grant of an Award, the making of a Purchase of Common
Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock or securities acquired on the exercise of an Option hereunder, or the
making of a distribution or other payment with respect to such stock or
securities, the Company may withhold taxes in respect of amounts that constitute
compensation includible in gross income. The Committee in its discretion may
condition (i) the exercise of an Option, (ii) the grant of an Award, (iii) the
making of a Purchase of Common Stock for less than its fair market value, or
(iv) the vesting or transferability of restricted stock or securities acquired
by exercising an Option, on the grantee's making satisfactory arrangement for
such withholding. Such arrangement may include payment by the grantee in cash or
by check of the amount of the withholding taxes or, at the discretion of the
Committee, by the grantee's delivery of previously held shares of Common Stock
or the withholding from the shares of Common Stock otherwise deliverable upon
exercise of a Option shares having an aggregate fair market value equal to the
amount of such withholding taxes.


                                      11
