                        2005 EMPLOYEE STOCK PURCHASE PLAN

1.   PURPOSE.

     The purpose of the Plan is to provide employees of the Company and its
Designated Subsidiaries with an opportunity to purchase Ordinary Shares of the
Company through accumulated payroll deductions.

     It is the intention of the Company to have the Plan qualify under varying
tax regimes in the jurisdictions in which the Company or its Designated
Subsidiaries have employees. The provisions of the Plan, accordingly, shall be
construed so as to extend and limit participation in a manner consistent with
the requirements of applicable laws of each such jurisdiction.

     The Plan was adopted by the Board of Directors of the Company on June 7,
2005 and approved by the Company's shareholders on September 29, 2005.

2.   DEFINITIONS.

     2.1. "Board" shall mean the Board of Directors of the Company.

     2.2. "Change in Control" means any of the following shareholder-approved
transactions to which the Company is a party:

          2.2.1. a merger or consolidation in which the Company is not the
surviving entity, except for (i) a transaction the principal purpose of which is
to change the jurisdiction in which the Company is incorporated, form a holding
company or effect a similar reorganization as to form and (ii) whereupon this
Plan and all Reserves are assumed or substituted by the successor entity;

          2.2.2. the sale, transfer, exchange or other disposition of all or
substantially all of the assets of the Company, in complete liquidation or
dissolution of the Company in a transaction not covered by the exceptions to
clause 2.2.1, above; or

          2.2.3. any reverse merger in which the Company is the surviving entity
but in which securities possessing more than fifty percent (50%) of the total
combined voting power of the Company's outstanding securities are transferred to
a person or persons different from those who held such securities immediately
prior to such merger.

     2.3. "Company" shall mean Saifun Semiconductors Ltd., a company
incorporated under the laws of the State of Israel, or any successor thereof.

     2.4. "Compensation" shall mean (i) the total compensation paid in cash by
the Company or a Designated Subsidiary, including, salaries, wages, bonuses,
incentive compensation, commissions, overtime pay and shift premium, plus (ii)

"Compensation" shall exclude all non-cash items, expenses, reimbursement, moving
or relocation allowances, cost-of-living equalization payments, car allowances,
imputed income attributable to car, cellular or life insurance, severance pay,
fringe benefits, contributions or benefits received under employee benefit,

individual's right to reemployment is not guaranteed either by statute or by
contract, the employment relationship shall be deemed to have terminated on the
91st day of such leave, unless approved otherwise for the purpose of this Plan
by the Board. Payroll deductions for an employee who has been on an unpaid leave
of absence will resume at the same rate as in effect prior to such leave upon
return to work unless changed by such employee or unless the employee has been
on an unpaid leave of absence throughout an entire Offering Period, in which

immediately preceding such date, or if Ordinary Shares were not traded on such
date, then on the next preceding date of which a trade occurred, as reported in
the Wall Street Journal, or such other source as the Board deems reliable;

          2.10.2. if the Ordinary Shares are not traded on an exchange but are
quoted on the Nasdaq National Market System or a successor quotation system, the
mean between the closing representative bid and asked prices for the Ordinary
Shares on the trading day immediately preceding such date as reported by the

first Trading Day of each calendar quarter and terminate on the last Trading Day
of that calendar quarter. The duration of Offering Periods may be changed
pursuant to Section 4 of this Plan.

     2.15. "Ordinary Shares" shall mean the Ordinary Shares, par value NIS 0.01
each, of the Company.

     2.16. "Plan" shall mean this 2005 Employee Stock Purchase Plan.

Discount Percentage of the lesser of (i) the Fair Market Value of an Ordinary
Share on the Exercise Date, or (ii) the Fair Market Value of an Ordinary Share

3.   ELIGIBILITY.

     3.1. Any Employee who shall be employed by the Company or a Designated
Subsidiary on a given Enrollment Date shall be eligible to participate in the
Plan.

     3.2. Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan if his or her participation
in the Plan is prohibited by any applicable law or by any collective bargaining
agreement to which the Employee is subject.

4.   OFFERING PERIODS.

                                        3
<PAGE>
     The Plan shall be implemented by consecutive Offering Periods with the
first offering period commencing on the Initial Trading Date, or on such other
date as the Board shall determine, and continuing thereafter until terminated in
accordance with Section 19 hereof. The Board shall have the power to change the
duration of Offering Periods (including the commencement dates thereof) with
respect to future offerings without shareholders approval if such change is
announced at least five (5) days prior to the scheduled beginning of the first
Offering Period to be affected thereafter.

5.   PARTICIPATION.

     5.1. An eligible Employee may become a participant in the Plan by
completing an enrollment form designated by the Board (which may include such
further provisions and limitations, as it may deem equitable and in the best
interests of the Company), on or before the date which is two (2) weeks prior to
the Enrollment Date or such other date designated by the Board.

     5.2. Payroll deductions for a participant shall commence on the first
payroll following the first day of the Offering Period and shall end on the last
payroll in the Offering Period to which such authorization is applicable, unless
sooner terminated by the participant as provided in Section 10 hereof.

6.   PAYROLL DEDUCTIONS.

     6.1. At the time a participant files his or her enrollment agreement, he or
she shall elect to have payroll deductions (or, when not allowed under any local
law or regulation, another form of payment) made on each pay day during the
Offering Period in an amount not exceeding fifteen percent (15%) of the
Compensation which he or she receives on each pay day during the Offering
Period. Payroll deductions may be permitted on the basis of flat dollar
contributions, or a percentage of compensation (in whole percentages only), as
determined by the Board; if not determined otherwise by the Board, such
deduction shall be a whole percentage of the Compensation.

     6.2. All payroll deductions made for a participant shall be credited to his
or her account under the Plan. A participant may not make any additional
payments into such account.

     6.3. A participant may discontinue his or her participation in the Plan as
provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions by completing or filing with the Company a new enrollment
form authorizing a change in payroll deduction rate. A participant shall make no
more than one election to make a participation rate change per Offering Period.
The Board may, in its discretion, further limit or expand the number of
participation rate changes allowed during any Offering Period. The change in
rate shall be effective with the first full payroll period following the
administrative deadline established by the Company. A participant's enrollment
form shall remain in effect for successive Offering Periods unless terminated as
provided in Section 10 hereof.

     6.4. Notwithstanding the foregoing, to the extent necessary for the Company
or any Designated Subsidiary to comply with any applicable law, a participant's
payroll deductions may be refunded to the participant, or decreased to zero
percent (0%), at any time in the sole discretion of the Board.

     6.5. At the time the option is exercised, in whole or in part, or at the
time some or all of the Company's Ordinary Shares issued under the Plan is
disposed of, the participant must

                                        4
<PAGE>
make adequate provision for the Company's federal, state, or other tax
withholding obligations, if any, which arise upon the exercise of the option or
the disposition of the Ordinary Shares and any tax consequences arising
therefrom shall be borne solely by the participant. At any time, the Company
may, but shall not be obligated to, withhold from the participant's compensation
the amount necessary for the Company to meet applicable withholding or other tax
obligations, including any withholding required to make available to the Company
or any tax deductions or benefits attributable to sale or early disposition of
Ordinary Shares by the Employee. The Company shall not be required to release
any share certificate to an Employee until all required payments have been fully
made, as evidenced in writing.

     6.6. The participant shall agree to indemnify the Company and any
Designated Subsidiary that employs or engages the participant, if applicable 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 Employee.

7.   GRANT OF OPTION.

     7.1. On the first day of each Offering Period, each eligible Employee
participating in such Offering Period shall be granted an option to purchase on
the Exercise Date of such Offering Period (at the applicable Purchase Price as
per section 2.17) up to a number of the Company's Ordinary Shares (the
"EXERCISED NUMBER OF SHARES") determined by dividing (i) such Employee's payroll
deductions accumulated prior to such Exercise Date and retained in the
Employee's account as of the Exercise Date by (ii) the applicable Purchase
Price; provided that such purchase shall be subject to the limitations set forth
in Sections 3.2 and 13 hereof and, if so determined by the Board, to the
limitations set forth in Section 7.2. Exercise of the option shall occur as
provided in Section 8 hereof, unless the participant has withdrawn pursuant to
Sections 10 or 11 hereof. The option shall expire on the last day of the
Offering Period.

     7.2. Notwithstanding anything to the contrary, the Board shall have the
power to limit the number of Ordinary Shares that may be purchased by an
Employee on account of a purchase option granted to an Employee to the Maximum
Number of Shares, notwithstanding the Fair Market Value as of the Exercise Date.
If the Board so determines, the Employee shall only be entitled to purchase such
Exercised Number of Shares which shall not exceed the Maximum Number of Shares
even if the Fair Market Value as of the Exercise Date is lower than the Fair
Market Value as of the Offering Date and the Employee shall not be entitled to
receive any return of payroll deductions credited to such Employee's account
during the Offering Period.

8.   EXERCISE OF OPTION.

     8.1. Unless a participant withdraws from the Plan as provided in Sections
10 or 11 hereof, his or her option for the purchase of shares shall be exercised
automatically on the Exercise Date, and the maximum number of shares subject to
option shall be purchased for such participant in accordance with the provisions
of Section 7, at the applicable Purchase Price with the accumulated payroll
deductions in his or her account. During a participant's lifetime, a
participant's option to purchase shares hereunder is exercisable only by him or
her. No fractional shares shall be purchased unless otherwise determined by the
Board; any payroll deductions accumulated in a participant's account under the
Plan that are not sufficient to purchase a full share shall be retained in such
account for the subsequent Offering Period, subject to earlier withdrawal by the
participant as provided in Sections 10 or 11. In the case of the participant's

                                        5
<PAGE>
death, any monies remaining in his or her account under the Plan after the
Exercise Date of an Offering Period shall be returned to the person or persons
entitled thereto, in cash.

     8.2. Prior to exercise, the Employees shall have none of the rights and/or
privileges of a shareholder of the Company in respect to any shares purchasable
upon the exercise of any part of an option (including but not limited to voting
right or dividend rights) nor shall they be deemed to be a class of shareholders
or creditors of the Company under applicable law, including Sections 350 and 351
of the Israeli Companies Law - 1999.

     8.3. Upon exercise of an option, an Employee shall have no shareholder
rights 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
(unless the shares are delivered electronically, in which case upon such
delivery). 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 shareholders' right, for which the record date precedes the date of
issuance of the shares, except as provided in Section 18 hereof.

9.   DELIVERY.

     As promptly as practicable after each Exercise Date on which a purchase of
shares occurs, the Company shall arrange the delivery to each participant or its
designated securities account or institution, as appropriate, of the shares
purchased upon exercise of his or her option.

10.  WITHDRAWAL.

     10.1. A participant may withdraw from the Plan at any time by giving notice
to the Company on the form designated by the Board, no later than two (2) weeks
prior to the last day of any Offering Period, or on or before any other date
designated by the Board. If a participant withdraws from the Plan, payroll
deductions shall not resume at the beginning of the succeeding Offering Period
unless the participant delivers to the Company a new enrollment form as provided
in Section 5.

     10.2. A participant's withdrawal from the Plan shall not have any effect
upon his or her eligibility to participate in any similar plan which may
hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     10.3. In the event a participant withdraws from the Plan prior to an
Exercise Date, any payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant.

11.  TERMINATION OF EMPLOYMENT.

     Upon a participant's ceasing to be an Employee for any reason, he or she
shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto and such
participant's option shall be automatically terminated.

12.  INTEREST.

     No interest shall accrue on the payroll deductions of a participant in the
Plan.

13.  STOCK.

                                        6
<PAGE>
     13.1. Subject to adjustment upon changes in capitalization of the Company
as provided in Section 18 hereof, the aggregate number of Ordinary Shares which
shall be made available by the Company for (i) sale under the Plan; and (ii)
allocation and exercise of options under the Company's 2003 Share Option Plan
((i) and (ii) shall be collectively referred to as the "AGGREGATE NUMBER OF
SHARES"), shall not exceed fifteen million (15,000,000) shares. Notwithstanding
the foregoing, the Aggregate Number of Shares shall be increased annually on
January 1st by a number of Ordinary Shares equal to the lowest of (a) 4% of the
total number of shares of the Company outstanding (on an as converted basis) as
of December 31st of the preceding calendar year, (b) 1,333,333 Shares, subject
to adjustment as provided in Section 18, or (c) number of Ordinary Shares
determined by the Board. The allocation of the Aggregate Number of Shares and
any increase thereof between the Plan and the Company's 2003 Share Option Plan
shall be decided at the discretion of the Board. If, on a given Exercise Date,
the number of shares with respect to which options are to be exercised exceeds
the number of shares then available under the Plan, the Company shall make a pro
rata allocation of the shares remaining available for purchase in as uniform a
manner as shall be practicable and as it shall determine to be equitable. Any
Ordinary Shares under the Plan, in respect of which the right hereunder of an
Employee to purchase the same shall for any reason terminate, become cancelled,
expire or otherwise cease to exist, shall again be available for grant through
options under the Plan. Furthermore, Ordinary Shares subject to options which
are adjusted pursuant to Section 18.1 and become exercisable with respect to
shares of another corporation shall be considered cancelled and may again be
optioned, granted or awarded hereunder, subject to the share limit set forth in
this Section 13.1. Shares which are actually or constructively delivered by the
Employee or withheld by the Company upon the exercise of an option in payment of
the exercise price thereof or tax withholding thereon may again be optioned,
granted or awarded hereunder.

     13.2. Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant (or, if required under applicable law,
in the name of a trustee for the benefit of the participant).

14.  ADMINISTRATION.

     The Plan shall be administered by the Board or a committee appointed by the
Board to administer the Plan and to perform the functions set forth herein. The
Board or its committee shall have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan. In the event that a
committee is appointed by the Board, any decision of the committee regarding the
Plan shall have the same effect as a decision by the Board, subject to the
provisions of any applicable law. Every finding, decision and determination made
by the Board or its committee shall, to the full extent permitted by law, be
final and binding upon all parties.

15.  TRANSFERABILITY.

     Neither payroll deductions credited to a participant's account nor any
rights with regard to the exercise of an option or to receive shares under the
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
(other than by will, or the laws of descent and distribution) by the
participant. Any such attempt at assignment, transfer, pledge or other
disposition shall be without effect, except that the Company may treat such act
as an election to withdraw funds from an Offering Period in accordance with
Sections 10 or 11 hereof.

                                        7
<PAGE>
16.  USE OF FUNDS.

     All payroll deductions received or held by the Company under the Plan may
be used by the Company for any corporate purpose, and the Company shall not be
obligated to segregate such payroll deductions.

17.  REPORTS.

     Individual accounts shall be maintained for each participant in the Plan.
Statements of account shall be given to participating Employees at least
annually, which statements shall set forth the amounts of payroll deductions,
the Purchase Price, the number of shares purchased (and the Maximum Number of
Shares, if applicable) and the remaining cash balance, if any.

18.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, LIQUIDATION,
     MERGER OR ASSET SALE.

     18.1. Changes in Capitalization and Distributions. Subject to any required
action by the shareholders of the Company, the Board shall, in such manner as it
may deem equitable, proportionately adjust any or all of the Reserves, the
maximum number of shares each participant may purchase per Offering Period
(pursuant to Section 7), as well as the price per share and the number of
Ordinary Shares covered by each option under the Plan which has not yet been
exercised, following any increase or decrease in the number of issued Ordinary
Shares resulting from a stock split, reverse stock split, stock dividend or
other stock distribution, recapitalization, reorganization, combination or
reclassification of the Ordinary Shares, or any other increase or decrease in
the number of Ordinary Shares effected without receipt of consideration by the
Company; provided, however, that conversion of any convertible securities of the
Company shall not be deemed to have been "effected without receipt of
consideration". Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. 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 Ordinary Shares subject to an option (subject to the provisions of Section
7).

     18.2. Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company in a transaction not covered by the exceptions to
clause 18.3, the Offering Period then in progress shall be shortened by setting
a new Exercise Date (for purposes of this paragraph only, the "NEW EXERCISE
DATE"), and shall terminate immediately prior to the consummation of such
proposed dissolution or liquidation, unless provided otherwise by the Board. The
New Exercise Date shall be before the date of the Company's proposed dissolution
or liquidation. The Board shall notify each participant, at least ten (10)
business days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Sections 10 or 11 hereof.

     18.3. Merger or Asset Sale. In the event of (i) a proposed merger or
consolidation in which the Company is not the surviving entity, except for a
transaction the principal purpose of which is to change the jurisdiction in
which the Company is incorporated, form a holding company or effect a similar
reorganization as to form; or (ii) a proposed sale of all or substantially all
of the assets of the Company, each outstanding option shall be assumed or an

                                        8
<PAGE>
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 Offering Period
then in progress shall be shortened by setting a new Exercise Date (for purposes
of this paragraph only, the "NEW EXERCISE DATE"). The New Exercise Date shall be
before the date of the Company's proposed sale or merger. The Board shall notify
each participant, at least ten (10) business days prior to the New Exercise
Date, that the Exercise Date for the participant's option has been changed to
the New Exercise Date and that the participant's option shall be exercised
automatically on the New Exercise Date, unless prior to such date the
participant has withdrawn from the Offering Period as provided in Sections 10 or
11 hereof.

     18.4. Plan Termination. Notwithstanding anything to the contrary set forth
herein, in the event of any Change in Control or other event described in this
Section 18 which results in Ordinary Shares or other securities of the Company
being exchanged for or converted into cash, securities (including securities of
another corporation) or other property, the Board will have the right to
terminate this Plan as of the date of the event or transaction, in which case
all Ordinary Shares covered by each option under the Plan which has not yet been
exercised shall, at the option of the Board (i) become the right to receive such
cash, securities or other property, net of any applicable exercise price; or
(ii) shall terminate, in which case, any payroll deductions credited to such
participant's account during the Offering Period but not yet used to exercise
the option shall be returned to such participant.

     18.5. Further Actions. In addition to and without derogating from the
provisions of section 18.1 - 18.4, in the event of (i) any Change in Control,
(ii) other event described in Section 18, (iii) any unusual or nonrecurring
transactions or events affecting the Company, any affiliate of the Company, or
the financial statements of the Company or any affiliate or (iv) of changes in
applicable laws, regulations or accounting principles, the Board, in its sole
discretion, and on such terms and conditions as it deems appropriate, is
authorized to take any one or more of the following actions or determinations,
with respect to the outstanding option under this Plan, by action taken prior to
the occurrence of the event, or at any other time, whenever the Board determines
that such action is appropriate in order to prevent dilution or enlargement of
the benefits or potential benefits intended to be made available under the Plan
or with respect to any outstanding option under this Plan, to facilitate such
transactions or events, or to give effect to such changes in laws, regulations
or principles:

          18.5.1. that the outstanding option shall be purchased for an amount
of cash equal to the amount that could have been attained upon the exercise of
such outstanding option or the realization of the Employee's rights had such
outstanding option been currently exercisable or payable;

          18.5.2. that the outstanding option shall be replaced with other
rights or property selected by the Board in its sole discretion;

          18.5.3. that the outstanding option cannot be exercised after such
event, in which case, any payroll deductions credited to such participant's
account during the Offering Period but not yet used to exercise the option shall
be returned to such participant;

          18.5.4. that, for a specified period of time prior to such transaction
or event, such outstanding option shall be exercisable as to all Ordinary Shares
covered thereby, notwithstanding anything to the contrary in this Plan or the
provisions of such outstanding option;

                                        9
<PAGE>
          18.5.5. that upon such event, such outstanding option shall be assumed
by the successor corporation, or a parent or subsidiary thereof, or shall be
substituted for by a similar outstanding option covering the stock of the
successor corporation, or a parent or subsidiary thereof, with appropriate

secondary or incidental offering), and (ii) in all other respects shall not
exceed the maximum assets of the Company available as permitted by law.

7. OTHER PAYMENT RECEIVED. The Company will not indemnify you for any liability
with respect to which you have received payment by virtue of an insurance
policy, exemption or another indemnification agreement other than for amounts
which are in excess of the amounts actually paid to you pursuant to any such
insurance policy, exemption or other indemnity agreement (including deductible
amounts not covered by insurance policies).

8. THIRD PARTY AMOUNTS. The Company will be entitled to any amount collected
from a third party in connection with liabilities indemnified hereunder.

9. LIMITATIONS. In all indemnifiable circumstances indemnification will be

to the Company, or to such person as it shall advise you, without delay all
documents you receive in connection with these proceedings, and provide such
other information and cooperation as the Company shall reasonably request;
provided however, that your failure to provide such notice or deliver such
documents shall not affect your right to indemnification hereunder unless and to
the extent such failure materially and adversely prejudices the Company's
ability to defend such proceedings.

     9.2. Other than with respect to proceedings that have been initiated
against you by the Company or in its name (i.e. derivative claims), the Company
shall be entitled to undertake the conduct of your defense in respect of such
legal proceedings and/or to hand over the conduct thereof to any attorney which
the Company may choose for that purpose, except under such circumstances
according to which there is reasonably likely to be conflict of interest between
you and the Company in the conduct of such defense.

     Notwithstanding the foregoing, you will be entitled to appoint at your own
expense an attorney of your own that shall accompany you in such procedure. Your
attorney shall be fully updated on the defense procedure, and the Company and
the attorney conducting the legal defense on behalf of the Company shall fully
cooperate with your attorney, including regularly consulting with your attorney
on the measures taken in the course of the defense.

     The Company and/or its attorney appointed by it as aforesaid shall be
entitled, within the context of the conduct as aforesaid, to conclude such
proceedings, all as it shall see fit, including by way of settlement. At the
request of the Company, you shall execute all documents reasonably required to
enable the Company and/or its attorney as aforesaid to conduct your defense in
your name, and to represent you in all matters connected therewith, in
accordance with the aforesaid.

     For the avoidance of doubt, in the case of criminal proceedings the Company
and/or its attorney as aforesaid will not have the right to plead guilty in your
name or to agree to a plea-bargain in your name without your written consent.
Furthermore, in a civil proceeding (whether before a court or as a part of a
compromise arrangement), the Company and/or its attorney will not have the right
to admit to any occurrences that are not indemnifiable pursuant to this Letter
of Indemnification and/or pursuant to applicable law, without your written
consent. However, the aforesaid will not prevent the Company and/or its attorney
as aforesaid, with the approval of the Company, coming to a financial
arrangement with a plaintiff in a civil

                                        4

                           D&O Indemnification Letter

proceeding without your consent so long as such arrangement will not be an
admittance of an occurrence not indemnifiable pursuant to this Letter of
Indemnification and/or pursuant to applicable law.

     9.3. You will fully cooperate with the Company and/or its attorney as
aforesaid in every reasonable way as may be required of you within the context
of their conduct of such legal proceedings, including but not limited to the
execution of power(s) of attorney and other documents, provided that the Company
shall cover all costs incidental thereto such that you will not be required to
pay the same or to finance the same yourself.

     9.4. If, in accordance with Section 9.2, the Company has taken upon itself
the conduct of your defense, the Company will have no liability or obligation
pursuant to this Letter of Indemnification or the above resolutions to indemnify
you for any legal expenses, including any legal fees, that you may expend in
connection with your defense, except to which the Company in its absolute
discretion shall agree and except for reasonable expenses incurred by you
pursuant to the second paragraph of Section 9.2 hereinabove.

     9.5. The Company will have no liability or obligation pursuant to this
Letter of Indemnification or the above resolutions to indemnify you for any
amount expended by you pursuant to any compromise or settlement agreement
reached in any suit, demand or other proceeding as aforesaid without the
Company's consent to such compromise or settlement.

     9.6. If required by law, the Company's authorized organs will consider the
request for indemnification and the amount thereof and will determine if you are
entitled to indemnification and the amount thereof.

10. COMPANY'S UNDERTAKING. If for the validation of any of the undertakings in
this Letter of Indemnification, any act, resolution, approval or other procedure
is required, the Company undertakes to cause them to be done or adopted in a
manner which will enable the Company to fulfill all its undertakings as
aforesaid.

11. RETROACTIVE INDEMNIFICATION. For the avoidance of doubt, it is hereby
clarified that nothing contained in this Letter of Indemnification or in the
above resolutions derogates from the Company's right upon its sole discretion,
to indemnify you post factum for any amounts which you may be obligated to pay
as set forth in Section 1 above without the limitations set forth in Sections 5
and/or 6 above.

12. SEVERABILITY. If any undertaking included in this Letter of Indemnification
is held invalid or unenforceable, such invalidity or unenforceability will not
affect any of the other undertakings which will remain in full force and effect.
Furthermore, if such invalid or unenforceable undertaking may be modified or
amended so as to be valid and enforceable as a matter of law, such undertakings
will be deemed to have been modified or amended, and any competent court or
arbitrator are hereby authorized to modify or amend such undertaking, so as to
be valid and enforceable to the maximum extent permitted by law.

agreement herein shall be governed by and construed and enforced in accordance
with the laws of the State of Israel without regard to the conflict of laws
thereof and the competent courts of Tel-Aviv/Yafo shall have exclusive
