                      PREDIX PHARMACEUTICALS HOLDINGS, INC.

                                SENIOR EXECUTIVE
                       NONSTATUTORY STOCK OPTION AGREEMENT
          GRANTED UNDER AMENDED AND RESTATED 2003 STOCK INCENTIVE PLAN

     1.   GRANT OF OPTION.

     This agreement evidences the grant by Predix Pharmaceuticals Holdings,
Inc., a Delaware corporation (the "Company"), on [INSERT DATE], 200_, (the
"Grant Date") to [INSERT NAME OF GRANTEE], an employee of the Company (the
"Participant"), of an option (the "Option") to purchase, in whole or in part, on
the terms provided herein and in the Company's Amended and Restated 2003 Stock
Incentive Plan (the "Plan"), a total of [INSERT # OF SHARES] shares (the
"Shares") of common stock, $0.01 par value per share, of the Company (the
"Common Stock") at a price of $_____ per Share (the "Exercise Price"). Unless
earlier terminated, this Option shall expire at 5:00 p.m., Eastern time, on
[INSERT DATE], 201__.

     It is intended that the Option evidenced by this agreement shall not be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended, and any regulations promulgated thereunder (the "Code").
Except as otherwise indicated by the context, the term "Participant", as used in
this option agreement, shall be deemed to include any person who acquires the
right to exercise this Option validly under its terms.

     2.   VESTING SCHEDULE.

     Subject to the terms and conditions of this Agreement, this Option to
purchase the Shares shall become exercisable ("vest") in 48 monthly
installments. Each installment shall consist of 2.0833% of the total number of
the Shares. Such installments shall become exercisable on the first day of each
month beginning on [INSERT DATE]. The number of shares included in each of the
first 47 installments shall be rounded down to the nearest whole number, whilst
the number of shares included in the 48th and final installment shall be the
remaining unvested balance of the Shares. [INSERT FOR NEW EMPLOYEES OR
CONSULTANTS THE FOLLOWING: NOTWITHSTANDING THE FOREGOING, THIS OPTION SHALL NOT
BE EXERCISABLE FOR ANY SHARES UNTIL THE DATE THAT THE PARTICIPANT HAS PROVIDED
SERVICES TO THE COMPANY OF ANY AFFILIATE THEREOF FOR A PERIOD OF ONE YEAR.]

     The right of exercise shall be cumulative so that to the extent the Option
is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all Shares for
which it is vested until the earlier of the Final Exercise Date or the
termination of this Option under Section 3 hereof or the Plan.

     Notwithstanding anything to the contrary herein and in addition to, and not
in contradiction with, the existing acceleration provisions provided under
Section 8(c) of the Plan, the Shares shall become immediately exercisable in
full if, after a Reorganization Event (as defined in the Plan), the acquiring or
succeeding entity assumes this Option or substitutes equivalent securities for
this Option, and (i) the Participant is terminated by the acquiring or
succeeding entity without "cause" (as defined in Section 3(e) below) within 12
months of the

                                       -3-
<PAGE>
consummation of such Reorganization Event, or (ii) the Participant terminates
his or her employment with the acquiring or succeeding entity within 12 months
of the consummation of such Reorganization Event due to a material adverse
change in the Participant's duties, authority or responsibilities (as of the
date of the consummation of the Reorganization Event) which causes the
Participant's position with the acquiring or succeeding entity to become of less
responsibility or authority; provided that, such Shares shall not become fully
exercisable after the Final Exercise Date or the termination of this Option
under Section 3 hereof or the Plan.

     3.   EXERCISE OF OPTION.

          (a) Form of Exercise. Each election to exercise this Option shall be
(i) by written notice in the form attached hereto as Exhibit A, duly signed by
the Participant and received by the Company or its designee, and (ii) payment in
full of the Exercise Price for each Share purchased upon exercise of this
Option. Payment of the Exercise Price for each Share shall be made in accordance
with Section 5(f) of the Plan. The Participant may purchase less than the number
of shares covered hereby, provided that no partial exercise of this Option may
be for any fractional share. The Company shall deliver such Shares as soon as
practicable after the notice shall be received, provided, however, that the
Company may delay issuance of such Shares until all conditions set forth in
Section 9(g) of the Plan have been satisfied. The Shares as to which the Option
shall have been so exercised shall be registered in the Company's share register
in the name of the person so exercising the Option (or, if the Option shall be
exercised by the Participant and if the Participant shall so request in the
notice exercising the Option, shall be registered in the name of the Participant
and another person jointly, with right of survivorship) and shall be delivered
as provided above to or upon the written order of the person exercising the
Option. In the event the Option shall be exercised, pursuant to Section 3(d)
hereof, by any person other than the Participant, such notice shall be
accompanied by appropriate proof of the right of such person to exercise the
Option.

          (b) Continuous Relationship with the Company Required. Except as
otherwise provided in this Section 3, this Option may not be exercised unless
the Participant, at the time he or she exercises this Option, is, and has been
at all times since the Grant Date, an employee or officer of, or consultant or
advisor to, the Company or any other entity whose employees are eligible to
receive options under the Plan (an "Eligible Participant").

          (c) Termination of Relationship with the Company. If the Participant
ceases to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this Option shall terminate
three months after such cessation (but in no event after the Final Exercise
Date), provided that this Option shall be exercisable only to the extent that
the Participant was entitled to exercise this Option on the date of such
cessation. Notwithstanding the foregoing, if the Participant, prior to the Final
Exercise Date, violates the non-competition or confidentiality provisions of any
employment contract, confidentiality and nondisclosure agreement or other
agreement between the Participant and the Company, the right to exercise this
Option shall terminate immediately upon written notice to the Participant from
the Company describing such violation.

          (d) Exercise Period Upon Death or Disability. If the Participant dies
or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior
to the Final

                                       -4-
<PAGE>
Exercise Date while he or she is an Eligible Participant and the Company has not
terminated such relationship for "Cause" as specified in paragraph (e) below,
this Option shall be exercisable, within the period of one year following the
date of death or disability of the Participant, by the Participant (or in the
case of death by an authorized transferee), provided that this Option shall be
exercisable only to the extent that this Option was exercisable by the
Participant on the date of his or her death or disability, and further provided
that this Option shall not be exercisable after the Final Exercise Date.

          (e) Discharge for Cause. If the Participant, prior to the Final
Exercise Date, is discharged by the Company for "Cause" (as defined below), the
right to exercise this Option shall terminate immediately upon notice of such
discharge. "Cause" shall mean willful misconduct by the Participant or willful
failure by the Participant to perform his or her responsibilities to the Company
(including, without limitation, breach by the Participant of any provision of
any employment, consulting, advisory, nondisclosure, non-competition or other
similar agreement between the Participant and the Company), as determined by the
Company, which determination shall be conclusive. The Participant shall be
considered to have been discharged for "Cause" if the Company determines, within
30 days after the Participant's resignation, that discharge for Cause was
warranted.

     4.   AGREEMENT IN CONNECTION WITH PUBLIC OFFERINGS.

     If, in connection with a registration statement filed by the Company
pursuant to the Securities Act of 1933, as amended, the Company or its
underwriter so requests, the Participant will agree not to sell any Shares for a
period not to exceed 180 days following the effectiveness of such registration.

     5.   WITHHOLDING.

     No Shares will be issued pursuant to the exercise of this Option unless and
until the Participant pays to the Company, or makes provision satisfactory to
the Company for payment of, any federal, state or local withholding taxes
required by law to be withheld in respect of this Option in accordance with
Section 9(e) of the Plan.

     6.   NONTRANSFERABILITY OF OPTION.

     (a) This Option may not be sold, assigned, transferred, pledged or
otherwise encumbered by the Participant, either voluntarily or by operation of
law, except by will or the laws of descent and distribution, and, during the
lifetime of the Participant, this Option shall be exercisable only by the
Participant.

     7.   PROVISIONS OF THE PLAN.

     This Option is subject to the provisions of the Plan, a copy of which is
furnished to the Participant with this Option.

     8.   NO OBLIGATION TO MAINTAIN RELATIONSHIP.

                                       -5-
<PAGE>
     The Company is not by the Plan or this Option obligated to continue the
Participant as an employee, director or consultant of the Company. The
Participant acknowledges: (i) that the Plan is discretionary in nature and may
be suspended or terminated by the Company at any time; (ii) that the grant of
the Option is a one-time benefit which does not create any contractual or other
right to receive future grants of options, or benefits in lieu of options; (iii)
that all determinations with respect to any such future grants, including, but
not limited to, the times when options shall be granted, the number of shares
subject to each option, the option price, and the time or times when each option
shall be exercisable, will be at the sole discretion of the Company; (iv) that
the Participant's participation in the Plan is voluntary; (v) that the value of
the Option is an extraordinary item of compensation which is outside the scope
of the Participant's employment contract, if any; and (vi) that the Option is
not part of normal or expected compensation for purposes of calculating any
severance, resignation, redundancy, end of service payments, bonuses,
long-service awards, pension or retirement benefits or similar payments.

     9.   GOVERNING LAW.

     This Agreement shall be construed and enforced in accordance with the law
of the State of Delaware, without giving effect to the conflict of law
principles thereof. For the purpose of litigating any dispute that arises under
this Agreement, the parties hereby consent to exclusive jurisdiction in
Massachusetts and agree that such litigation shall be conducted in the courts of
Middlesex County, Massachusetts or the federal courts of the United States for
the District of Massachusetts.

     10.  BENEFIT OF AGREEMENT.

     Subject to the provisions of the Plan and the other provisions hereof, this
Agreement shall be for the benefit of and shall be binding upon the heirs,
executors, administrators, successors and assigns of the parties hereto.

     11.  ENTIRE AGREEMENT.

     This Agreement, together with the Plan, embodies the entire agreement and
understanding between the parties hereto with respect to the subject matter
hereof and supersedes all prior oral or written agreements and understandings
relating to the subject matter hereof. No statement, representation, warranty,
covenant or agreement not expressly set forth in this Agreement shall affect or
be used to interpret, change or restrict the express terms and provisions of
this Agreement, provided, however, in any event, this Agreement shall be subject
to and governed by the Plan.

     12.  MODIFICATIONS AND AMENDMENTS.

     The terms and provisions of this Agreement may be modified or amended as
provided in the Plan.

     13.  DATA PRIVACY.

                                       -6-

     By entering into this Agreement, the Participant: (i) authorizes the
Company and each affiliate, and any agent of the Company or any affiliate
administering the Plan or providing Plan record keeping services, to disclose to
the Company or any of its affiliates such information and data as the Company or
any such affiliate shall request in order to facilitate the grant of options and
the administration of the Plan; (ii) waives any data privacy rights he or she

                             STOCK OPTION AGREEMENT
 GRANTED UNDER APPENDIX A OF THE AMENDED AND RESTATED 2003 STOCK INCENTIVE PLAN

      (INTENDED FOR ISRAELI RESIDENTS QUALIFYING UNDER SECTION 102(B)(2) -
                             "CAPITAL GAINS TRACK")

     This option agreement is made this [DAY] day of [MONTH, YEAR], between
Predix Pharmaceuticals Holdings, Inc., a Delaware corporation (the "Company"),
and [EMPLOYEE NAME], ID Number [EMPLOYEE ID NO.], (the "Participant").

     Unless otherwise defined herein, capitalized terms used in this option
agreement shall have the same meanings as ascribed to them in Predix
Pharmaceuticals Holdings, Inc. Amended and Restated 2003 Stock Incentive Plan,
including Appendix A thereof (the "Plan").

     For valuable consideration, receipt of which is acknowledged, the parties
hereto agree as follows:

     1.   GRANT OF OPTION.

     (a) This option agreement evidences the grant by Predix Pharmaceuticals
Holdings, Inc., a Delaware corporation (the "Company"), on [DATE] (the "Grant
Date") to [EMPLOYEE NAME], ID Number [EMPLOYEE ID NO.], an Employee of the
Company's subsidiary (the "Eligible 102 Participant"), of an option (the
"Option") to purchase, in whole or in part, on the terms provided herein and in
the Company's Amended and Restated 2003 Stock Incentive Plan (the "Plan"), a
total of [NUMBER OF SHARES] shares (the "Shares") of common stock, $0.01 par
value per share, of the Company (the "Common Stock") at a price of $___ per
Share (the "Exercise Price"). Unless earlier terminated, this Option shall
expire at 5:00 p.m., Eastern time, on [10 YEARS FROM GRANT DATE] (the "Final
Exercise Date"). The Option grant is subject to the terms and conditions of
Section 102(b)(2) of the Income Tax Ordinance (New Version) - 1961, the Plan,
which is incorporated herein by reference, and the Trust Agreement, entered into
between the Company and Yoram Wilamowski of Ernst & Young (the "Trustee"). The
options evidenced by this Option grant are intended to qualify as 102 Capital
Gains Track Options. In the event of a conflict between the terms and conditions
of the Plan and this option agreement, the terms and conditions of the Plan
shall prevail. However, Sections 1 and 2 of this option agreement set out
specific terms for the Eligible 102 Participant hereunder, and will prevail over
more general terms in the Plan, if any, or in the event of a conflict between
this option agreement and the Plan.

     (b) Issuance of Options in Compliance with Section 102 of the Israeli Tax
Ordinance. The Options will be registered in the Company's records in the name
of the Trustee as required by law to qualify under Section 102. The Eligible 102
Participant shall comply with the Ordinance, the Rules, and the terms and
conditions of the Trust Agreement entered into between the Company and the
Trustee. The Trustee will hold the Options or the Shares to be issued upon
exercise of the Options for the Required Holding Period, as set forth in the
Plan. The Required Holding Period for 102 Capital Gains Track Options pursuant
to the provisions of the ITO is 24
<PAGE>
months from the end of the tax year during which the Options are granted. The
Eligible 102 Participant hereby undertakes to release the Trustee from any
liability in respect of any action or decision duly taken and bona fide executed
in relation to the Plan, or any Option or Share granted to him thereunder. The
Eligible 102 Participant hereby confirms that he or she shall execute any and
all documents which the Company or the Trustee may reasonably determine to be
necessary in order to comply with the ITO and particularly the Rules.

     Except as otherwise indicated by the context, the term "Eligible 102
Participant", as used in this option agreement, shall be deemed to include any
person who acquires the right to exercise this Option validly under its terms.

     2.   VESTING SCHEDULE.

     Subject to the terms and conditions of this option agreement, this Option
to purchase the Shares shall become exercisable ("vest") in 48 monthly
installments. Each installment shall consist of 2.0833% of the total number of
the Shares. Such installments shall become exercisable on the first day of each
month beginning on [INSERT DATE]. The number of shares included in each of the
first 47 installments shall be rounded down to the nearest whole number, whilst
the number of shares included in the 48th and final installment shall be the
remaining unvested balance of the Shares. [FOR NEW EMPLOYEES ONLY:
NOTWITHSTANDING THE FOREGOING, THIS OPTION SHALL NOT BE EXERCISABLE FOR ANY
SHARES UNTIL THE DATE THAT THE PARTICIPANT HAS BEEN EMPLOYED BY THE COMPANY OR
ANY AFFILIATE THEREOF FOR A PERIOD OF ONE YEAR.]

     The right of exercise shall be cumulative so that to the extent the Option
is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all Shares for
which it is vested until the earlier of the Final Exercise Date or the
termination of this Option under Section 3 hereof or the Plan.

     Notwithstanding anything to the contrary herein and in addition to, and not
in contradiction with, the existing acceleration provisions provided under
Section 8(c) of the Plan, the Shares shall become immediately exercisable in
full if, after a Reorganization Event (as defined in the Plan), the acquiring or
succeeding entity assumes this Option or substitute equivalent securities for
this Option, and (i) the Eligible 102 Participant is terminated by the acquiring
or succeeding entity without "cause" (a defined in Section 3(f) below) within 12
months of the consummation of such Reorganization Event, or (ii) the Eligible
102 Participant terminates his or her employment with the acquiring or
succeeding entity within 12 months of the consummation of such Reorganization
Event due to a material adverse change in the Eligible 102 Participant's duties,
authority or responsibilities (as of the date of the consummation of the
Reorganization Event) which causes the Eligible 102 Participant's position with
the acquiring or succeeding entity to become of less responsibility or
authority; provided that, such Shares shall not become fully exercisable after
the Final Exercise Date or the termination of this Option under Section 3 hereof
or the Plan.

<PAGE>
     3.   EXERCISE OF OPTION.

          (a) Form of Exercise. Each election to exercise this Option shall be
(i) by written notice in the form attached hereto as Exhibit A, or in such other
form as the Company and/or the Trustee may from time to time prescribe, duly
signed by the Eligible 102 Participant and received by the Company or its
designee (and the Trustee, where applicable) and (ii) payment in full of the
Exercise Price for each Share purchased upon exercise of this Option. Payment of
the Exercise Price for each Share shall be made in accordance with Section 5(f)
of the Plan. The Eligible 102 Participant may purchase less than the number of
shares covered hereby, provided that no partial exercise of this Option may be
for any fractional share. The Company shall deliver such Shares as soon as
practicable after the notice shall be received, provided, however, that the
Company may delay issuance of such Shares until all conditions set forth in the
Plan and this option agreement have been satisfied.

          (b) Compliance with Section 102 Upon Exercise of Options. The Company
or its designee will notify the Trustee of any exercise of Options as set forth
in the written notice form. If such notification is delivered during the
Required Holding Period, the Shares issued upon the exercise of the Options
shall be issued in the name of the Trustee, and held in trust on the Eligible
102 Participant's behalf by the Trustee. In the event that such notification is
delivered after the end of the Required Holding Period, the Shares issued upon
the exercise of the Options shall, at the election of the Eligible 102
Participant, either (i) be issued in the name of the Trustee, or (ii) be
transferred to the Eligible 102 Participant directly, provided that the Eligible
102 Participant first complies with the provisions of Section 5 below. In the
event that the Eligible 102 Participant elects to have the Shares transferred to
the Eligible 102 Participant without selling such Shares, the Eligible 102
Participant shall become liable to pay taxes immediately at the rate prescribed
by law.

          (c) Continuous Relationship with the Company Required. Except as
otherwise provided in this Section 3, this Option may not be exercised unless
the Eligible 102 Participant, at the time of vesting of Options hereunder, is,
and has been at all times since the Grant Date, an employee, office holder or
director of the Company or an Affiliate whose employees, office holders or
directors are considered Eligible 102 Participants.

          (d) Termination of Relationship with the Company. If the Eligible 102
Participant ceases to be an Eligible 102 Participant for any reason, then,
except as provided in paragraphs (e) and (f) below, the right to exercise this
Option shall terminate three months after such cessation (but in no event after
the Final Exercise Date), provided that this Option shall be exercisable only to
the extent that the Eligible 102 Participant was entitled to exercise this
Option on the date of such cessation. Notwithstanding the foregoing, if the
Eligible 102 Participant, prior to the Final Exercise Date, violates the
non-competition or confidentiality provisions of any employment contract,
confidentiality and nondisclosure agreement or other agreement between the
Eligible 102 Participant and the Company, the right to exercise this Option
shall terminate immediately upon written notice to the Eligible 102 Participant
from the Company describing such violation.

          (e) Exercise Period Upon Death or Disability. If the Eligible 102
Participant dies or becomes disabled (within the meaning of Section 22(e)(3) of
the Code) prior to the Final

                                        3
<PAGE>
Exercise Date while he or she is an Eligible 102 Participant and the Company, or
its Affiliate, as applicable, has not terminated such relationship for "Cause"
as specified in paragraph (f) below, this Option shall be exercisable, within
the period of one year following the date of death or disability of the Eligible
102 Participant, by the Eligible 102 Participant (or in the case of death by an
authorized transferee), provided that this Option shall be exercisable only to
the extent that this Option was exercisable by the Eligible 102 Participant on
the date of his or her death or disability, and further provided that this
Option shall not be exercisable after the Final Exercise Date.

          (f) Discharge for Cause. If the Eligible 102 Participant, prior to the
Final Exercise Date, is discharged by the Company, or its Affiliate, as
applicable, for "Cause" (as defined below), the right to exercise this Option
shall terminate immediately upon notice of such discharge. "Cause" shall mean
willful misconduct by the Eligible 102 Participant or willful failure by the
Eligible 102 Participant to perform his or her responsibilities to the Company
or its Affiliate, as applicable (including, without limitation, breach by the
Eligible 102 Participant of any provision of any employment, consulting,
advisory, nondisclosure, non-competition or other similar agreement between the
Eligible 102 Participant and the Company), as determined by the Company, which
determination shall be conclusive. The Eligible 102 Participant shall be
considered to have been discharged for "Cause" if the Company determines, within
30 days after the Eligible 102 Participant's resignation, that discharge for
Cause was warranted.

          (g) Release of Options from Trust. Upon the end of the Required
Holding Period or as otherwise provided in the Plan, the Eligible 102
Participant shall be entitled to (i) receive from the Trustee all Options which
have vested, (ii) exercise the Options and (iii) sell the Shares thereby
obtained subject to the other terms and conditions of this option agreement and
the Plan, including in particular provisions relating to the payment of tax, as
set out in Section 5 below.

     4.   AGREEMENT IN CONNECTION WITH PUBLIC OFFERINGS.

     If in connection with a registration statement filed by the Company
pursuant to the United States Securities Act of 1933, as amended, the Company or
its underwriter so requests, the Eligible 102 Participant will agree not to Sell
any Shares for a period not to exceed 180 days following the effectiveness of
such registration statement.

     5.   WITHHOLDING.

     Any tax consequences arising from the grant or exercise of this Option,
from the payment for Shares covered thereby, the issuance of Shares, or from any
other event or act of the Company, and/or its Affiliates, the Trustee or the
Eligible 102 Participant hereunder, shall be borne solely by the Eligible 102
Participant. The Company and/or its Affiliates, and/or the Trustee shall
withhold taxes as required under applicable laws, rules, and regulations,
including as required by the ITO and the Rules. No Shares will be issued
pursuant to the exercise of this Option unless and until the Eligible 102
Participant pays to the Company, or makes provision satisfactory to the Company
for payment of, any applicable withholding taxes required by law to be withheld
in respect of this Option. The Company or any of its Affiliates and the Trustee
may make such provisions and take such steps as it may deem necessary or
appropriate for the

                                        4
<PAGE>
withholding of all taxes required by law to be withheld with respect to Options
granted under the Plan and the exercise thereof, including, but not limited, to
(i) deducting the amount so required to be withheld from any other amount then
or thereafter payable to a Eligible 102 Participant, and/or (ii) requiring an
Eligible 102 Participant to pay to the Company or any of its Affiliates the
amount so required to be withheld as a condition of the issuance, delivery,
distribution or release of any Shares. In addition, the Eligible 102 Participant
will be required to pay any amount which exceeds the tax to be withheld and
transferred to the tax authorities, pursuant to applicable Israeli tax
regulations. Furthermore, the Eligible 102 Participant shall agree to indemnify
the Company and/or its Affiliates and/or the Trustee and hold them harmless
against and from any and all liability for any such tax or interest or penalty
thereon, including without limitation, liabilities relating to the necessity to
withhold, or to have withheld, any such tax from any payment made to the
Eligible 102 Participant.

     6.   NONTRANSFERABILITY OF OPTION.

     This Option may not be sold, assigned, transferred, pledged or otherwise
encumbered by the Eligible 102 Participant, either voluntarily or by operation
of law, except by will or the laws of descent and distribution, and, during the
lifetime of the Eligible 102 Participant, this Option shall be exercisable only
by the Eligible 102 Participant. The transfer of the Options is further limited
as set forth in the Plan.

     As long as the Options and/or Shares are held by the Trustee on behalf of
the Eligible 102 Participant, all rights of the Eligible 102 Participant over
the Shares are personal, can not be transferred, assigned, pledge or mortgaged,
other than by will or pursuant to the laws of descent and distribution.

     7.   MISCELLANEOUS.

     (a) Continued Engagement. The Eligible 102 Participant acknowledges and
agrees that this option agreement, the transactions contemplated hereunder and
the vesting schedule set forth herein do not constitute an express or implied
promise of continued engagement as an employee, office holder or director for
the vesting period, for any period, or at all, shall not interfere in any way
with the Eligible 102 Participant's right or the right of the Company or its
Affiliate to terminate the Eligible 102 Participant's relationship as an
employee, office holder or director at any time, with or without cause, and
shall not constitute an express or implied promise or obligation of the Company
to grant additional Options to Eligible 102 Participant in the future.

     (b) Governing Law. This option agreement shall be governed by and construed
and enforced in accordance with the laws of the State of Israel, without giving
effect to the rules respecting conflict of law. Notwithstanding the foregoing,
all matters directly related to the share capital of the Company or other
internal corporate issues relating to the Company shall be governed by and
construed and enforced in accordance with the laws of the State of Delaware,
without giving effect to the rules respecting conflict of law.

     (c) Entire Agreement. This option agreement, together with the Plan and the
Trust Agreement, constitutes the entire agreement between the parties hereto and
supersedes all prior agreements, understandings and arrangements, oral or
written, between the parties hereto with respect to the subject matter hereof.
No agreement or representations, oral or otherwise, express

                                        5
<PAGE>
or implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this option agreement, the Plan and
the Trust Agreement.

     (d) Modifications And Amendments. The terms and provisions of this
Agreement may be modified or amended as provided in the Plan.

     (e) Data Privacy. By entering into this Agreement, the Eligible 102
Participant: (i) authorizes the Company and each affiliate, and any agent of the
Company or any affiliate administering the Plan or providing Plan record keeping
services, to disclose to the Company or any of its affiliates such information
and data as the Company or any such affiliate shall request in order to
facilitate the grant of options and the administration of the Plan; (ii) waives
any data privacy rights he or she may have with respect to such information; and
(iii) authorizes the Company and each affiliate to store and transmit such
information in electronic form.
