become available for future distribution under the Plan.

     4.   ADMINISTRATION OF THE PLAN.

          (a) PROCEDURE. The Plan shall be administered by the Administrator.

          (b) POWERS OF THE ADMINISTRATOR. Subject to the provisions of the Plan
and the approval of any relevant authorities, the Administrator shall have the
authority, in its discretion:

               (i) to determine the Fair Market Value;

               (ii) to select the Service Providers to whom Options may
from time to time be granted hereunder;

               (iii) to determine the number of Shares to be covered by each

                                       3
<PAGE>

               (vi) to determine whether and under what circumstances an Option
may be settled in cash under subsection 9(e) instead of Shares;

               (vii) to reduce the exercise price of any Option to the then
current Fair Market Value (or the nominal value of the Shares, if higher than
the Fair Market Value), if the Fair Market Value of the Shares covered by such
Option has declined since the date the Option was granted;

               (viii) to prescribe, amend and rescind rules and regulations
relating to the Plan;

               (ix) to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

          (c) EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

     5.   ELIGIBILITY. Nonstatutory Stock Options may be granted to Service
Providers. Incentive Stock Options may be granted only to Employees.

     6.   LIMITATIONS.

          (a) Each Option shall be designated in the Option Agreement as either
an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

          (b) Neither the Plan nor any Option shall confer upon an Optionee any
right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

          (c) The following limitations shall apply to grants of Options:

               (i) No Service Provider shall be granted, in any fiscal year of
the Company, Options to purchase more than 1,500,000 Shares.

               (ii) In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 3,000,000
Shares, which shall not count against the limit set forth in subsection (i)
above.

               (iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 12.

                                       4
<PAGE>

               (iv) If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 12), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     7.   TERM OF PLAN. The Plan shall become effective upon its adoption by the
Board. It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 14 of the Plan.

     8.   TERM OF OPTION. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns shares representing
more than ten percent (10%) of the voting power of all classes of shares of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

     9.   OPTION EXERCISE PRICE AND CONSIDERATION.

          (a) The per share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

               (i) In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns shares representing more than ten percent
(10%) of the voting power of all classes of shares of the Company or any Parent
or Subsidiary, the exercise price shall be no less than 110% of the Fair Market
Value per Share on the date of grant.

                    (B) granted to any Employee other than an Employee described
in the preceding subparagraph, the per Share exercise price shall be no less
than 100% of the Fair Market Value per Share on the date of grant.

               (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator.

               (iii) Notwithstanding the foregoing, Options may be granted with
a per Share exercise price (other than as required above) of less than 100% of
Fair Market Value on the date of grant pursuant to a merger or other corporate
transaction.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) consideration received by the Company under a formal cashless
exercise program adopted by the Company in connection with the Plan, (4) any
other type of consideration permitted by Applicable Laws, or (5) any combination
of the foregoing methods of payment. To the

                                       5
<PAGE>

extent that the consideration paid for the Shares is denominated in a
currency other than New Israeli Shekels, the exchange rate to be used to obtain
a New Israeli Shekel value of such consideration shall be the noon buying rate
as reported by the Federal Reserve Bank of New York (expressed in shekels per
unit of non-Israeli currency) on the date of grant of the Option. In making its
determination as to the type of consideration to accept, the Administrator shall
consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

     10.  EXERCISE OF OPTION.

          (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Options shall become exercisable at a rate to be
determined by the Administrator. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

              An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in (i) the name of the Optionee or,
if requested by the Optionee, in the name of the Optionee and his or her spouse,
or (ii) the name of the Optionee to [__________] as trustee (the "Trustee"), to
be held by the Trustee on behalf of Optionee if so required by Applicable Laws.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

              Exercise of an Option in any manner shall result in a decrease in
the number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

          (b) TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an Optionee
ceases to be a Service Provider, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

                                       6
<PAGE>

          (c) DISABILITY OF OPTIONEE. If an Optionee ceases to be a Service
Provider as a result of the Optionee's disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination, but in no event
later than the expiration date of the term of such Option as set forth in the
Option Agreement. In the absence of a specified time in the Option Agreement,
the Option shall remain exercisable for twelve (12) months following the
Optionee's termination. If, on the date of termination, the Optionee is not
vested as to the entire Option, the Shares covered by the unvested portion of
the Option shall revert to the Plan. If, after termination, the Option is not
exercised within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan. If such disability is
not a "disability" as such term is defined in Section 22(e)(3) of the Code, in
the case of an Incentive Stock Option such Incentive Stock Option shall
automatically cease to be treated as an Incentive Stock Option and shall be
treated for tax purposes as a Nonstatutory Stock Option on the day three months
and one day following such termination.

          (d) DEATH OF OPTIONEE. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement to the extent that the Option is vested on the date of death
(but in no event later than the expiration of the term of such Option as set
forth in the Option Agreement) by the Optionee's estate or by a person who
acquires the right to exercise the Option by bequest or inheritance. In the
absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's termination. If, at
the time of death, the Optionee is not vested as to the entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If the Option is not so exercised within the time specified herein, the Option
shall terminate, and the Shares covered by such Option shall revert to the Plan.

     11.  NON-TRANSFERABILITY OF OPTIONS. Unless determined otherwise by the
Administrator, Options may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

     12.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

          (a) CHANGES IN CAPITALIZATION. In the event the Shares shall be
subdivided or combined into a greater or smaller number of Shares or if, upon a
reorganization, recapitalization or the like, the Shares shall be exchanged for
other securities of the Company, each Optionee shall be entitled, subject to the
conditions herein stated, to purchase such number of Shares or amount of other
securities of the Company as were exchangeable for the number of Shares of the
Company which such Optionee would have been entitled to purchase except for such
action, and appropriate adjustments shall be made in the purchase price per
share to reflect such subdivision, combination or exchange.

          In the event that the Company shall issue any of its Shares or other
securities as bonus shares or a stock dividend upon or with respect to any
Shares which shall at the time be subject to an Option hereunder, each Optionee
upon exercising such Option shall be entitled to receive (for the purchase price
payable upon such exercise), the Shares as to which he or she is exercising such
Option and, in addition thereto (at no additional cost), such number of shares
of the

                                       7
<PAGE>

class or classes in which such bonus shares or stock dividend were declared, and
such amount of Shares (and the amount in lieu of fractional Shares) as is equal
to the Shares which he would have received had he been the holder of the Shares
as to which he is exercising his Option at all times between the date of the
granting of such Option and the date of its exercise.

               Upon the occurrence of any of the foregoing events, the class and
aggregate number of Shares or other securities issuable pursuant to the Plan, in
respect of which Options have not yet been granted, shall also be appropriately
adjusted to reflect the events specified above. If the Company offers the
holders of the Shares, or of any other class of security for which the Options
are then exercisable, rights to purchase securities of the Company, then the
Company shall offer the same rights to the Optionees as if they had exercised
their Options on the record date with respect to such rights offering.

          (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until fifteen (15) days prior to
such transaction as to all of the Optioned Shares, including Shares as to which
the Option would not otherwise be exercisable. To the extent it has not been
previously exercised, an Option will terminate immediately prior to the
consummation of such proposed action.

          (c) MERGER OR ASSET SALE. In the event of a merger of the Company with
or into another corporation, or the sale of substantially all of the assets of
the Company, each outstanding Option shall be assumed or an equivalent option
substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to
assume or substitute for the Option, the Optionee shall fully vest in and have
the right to exercise the Option as to all of the Optioned Shares, including
Shares as to which it would not otherwise be vested or exercisable. For the
purposes of this paragraph, the Option shall be considered assumed if, following
the merger or sale of assets, the option confers the right to purchase or
receive, for each Optioned Shares immediately prior to the merger or sale of
assets, the consideration (whether shares, cash, or other securities or
property) received in the merger or sale of assets by holders of Shares for each
Share held on the effective date of the transaction (and if such holders were
offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the merger or sale of assets is not solely
ordinary shares (or their equivalent) of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option,
for each Optioned Share, to be solely ordinary shares (or their equivalent) of
the successor corporation or its Parent equal in fair market value to the per
Share consideration received by holders of in the merger or sale of assets.

     13.  DATE OF GRANT. The date of grant of an Option shall, for all purposes,
be the date on which the Administrator makes the determination granting such
Option, or such other date as is determined by the Board. Notice of the
determination shall be given to each Service Provider to whom an Option is so
granted within a reasonable time after the date of such grant.

     14.  AMENDMENT AND TERMINATION OF THE PLAN.

                                       8
<PAGE>

          (a) AMENDMENT AND TERMINATION. The Board may at any time amend, alter,
suspend or terminate the Plan.

          (b) SHAREHOLDER APPROVAL. The Board shall obtain shareholder approval
of any Plan amendment to the extent necessary and desirable to comply with
Applicable Laws.

          (c) EFFECT OF AMENDMENT OR TERMINATION. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

     15.  CONDITIONS UPON ISSUANCE OF SHARES.

          (a) LEGAL COMPLIANCE. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

          (b) INVESTMENT REPRESENTATIONS. As a condition to the exercise of an
Option, the Administrator may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

     16.  INABILITY TO OBTAIN AUTHORITY. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder, shall relieve the Company of any liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     17.  RESERVATION OF SHARES. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     18.  SHAREHOLDER APPROVAL. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Option grants to Office Holders shall also be subject to approval by
the shareholders of the Company. In each case, such shareholder approval shall
be obtained in the manner and to the degree, if any, required under Applicable
Laws and the Articles of Association of the Company.

                                       9
