             Options and Approved 102 Options  shall be subject to the terms and
             conditions  set  forth  in  Section  102 of the  Ordinance  and the
             regulations promulgated thereunder.

     5.9     With regards to Approved 102 Options,  the  provisions  of the ISOP
             and/or the Option  Agreement  shall be subject to the provisions of
             Section 102 and the Tax Assessing  Officer's  permit,  and the said
             provisions  and permit shall be deemed an integral part of the ISOP
             and of the Option  Agreement.  Any  provision of Section 102 and/or
             the said permit which is  necessary  in order to receive  and/or to
             keep  any  tax  benefit  pursuant  to  Section  102,  which  is not
             expressly  specified in the ISOP or the Option Agreement,  shall be
             considered binding upon the Company and the Optionees.

6.   TRUSTEE

     6.1     Approved 102 Options  which shall be granted  under the ISOP and/or
             any Shares  allocated or issued upon  exercise of such Approved 102
             Options  and/or other shares  received  subsequently  following any
             realization of rights,  including without  limitation bonus shares,
             shall  be  allocated  or  issued  to the  Trustee  and held for the
             benefit of the  Optionees  for such  period of time as  required by
             Section  102 or any  regulations,  rules or  orders  or  procedures
             promulgated  thereunder  (the  "Holding  Period").  In the case the
             requirements  for  Approved  102  Options  are not  met,  then  the
             Approved 102 Options may be treated as Unapproved 102 Options,  all
             in accordance  with the  provisions of Section 102 and  regulations
             promulgated thereunder.

                                       8

                                       9


     6.2     Notwithstanding  anything to the  contrary,  the Trustee  shall not
             release any Shares  allocated  or issued upon  exercise of Approved
             102  Options  prior  to the  full  payment  of the  Optionee's  tax
             liabilities arising from Approved 102 Options which were granted to
             him and/or any Shares  allocated  or issued  upon  exercise of such
             Options.

     6.3     With respect to any Approved 102 Option,  subject to the provisions
             of Section 102 and any rules or  regulation or orders or procedures
             promulgated thereunder,  an Optionee shall not sell or release from
             trust any Share  received  upon the  exercise  of an  Approved  102
             Option  and/or  any  share  received  subsequently   following  any
             realization of rights, including without limitation,  bonus shares,
             until the lapse of the Holding Period required under Section 102 of
             the  Ordinance.  Notwithstanding  the  above,  if any such  sale or
             release  occurs  during the Holding  Period,  the  sanctions  under
             Section 102 of the  Ordinance  and under any rules or regulation or
             orders or  procedures  promulgated  thereunder  shall  apply to and
             shall be borne by such Optionee.

     6.4     Upon  receipt of Approved  102 Option,  the  Optionee  will sign an
             undertaking to release the Trustee from any liability in respect of
             any  action  or  decision  duly  taken and bona  fide  executed  in
             relation with the ISOP, or any Approved 102 Option or Share granted
             to him thereunder.

7.   SHARES RESERVED FOR THE ISOP; RESTRICTION THEREON

     7.1     The  Company  has  reserved  11,460,000  authorized  Shares for the
             purposes of the ISOP and for the purposes of the Commtouch Software
             Ltd.  Amended and Restated 1996 CSI Stock Option Plan and any other
             share  option  plans  which may be  adopted  by the  Company in the
             future,  subject to adjustment as set forth in Section 9 below. Any
             Shares  which  remain  unissued  and which are not  subject  to the
             outstanding  Options at the  termination of the ISOP shall cease to
             be reserved for the purpose of the ISOP,  but until  termination of
             the ISOP the Company shall at all times reserve  sufficient  number
             of Shares to meet the  requirements of the ISOP.  Should any Option
             for any  reason  expire or be  canceled  prior to its  exercise  or
             relinquishment in full, the Shares subject to such Option may again
             be  subjected  to an Option  under the ISOP or under the  Company's
             other share option plans.

     7.2     Each Option granted  pursuant to the ISOP,  shall be evidenced by a
             written Option Agreement  between the Company and the Optionee,  in
             such form as the  Board or the  Committee  shall  from time to time
             approve.  Each Option  Agreement shall state,  among other matters,
             the  number  of Shares to which  the  Option  relates,  the type of
             Option  granted  thereunder  (whether a CGO,  OIO,  Unapproved  102
             Option or a 3(i) Option), the Vesting Dates, the Purchase Price per
             share,  the Expiration  Date and such other terms and conditions as
             the  Committee  or the  Board  in  its  discretion  may  prescribe,
             provided that they are consistent with this ISOP.

8.   PURCHASE  PRICE

     8.1     The  Purchase  Price of each Share  subject  to an Option  shall be
             determined by the Committee in its sole and absolute  discretion in
             accordance with applicable law, subject to any guidelines as may be
             determined  by the Board from time to time.  Each Option  Agreement
             will contain the Purchase Price determined for each Optionee.

                                       9

                                       10


     8.2     The Purchase Price shall be payable upon the exercise of the Option
             in  a  form  satisfactory  to  the  Committee,   including  without
             limitation,  by  cash  or  check.  The  Committee  shall  have  the
             authority  to postpone  the date of payment on such terms as it may
             determine.

     8.3     The  Purchase  Price shall be  denominated  in the  currency of the
             primary economic environment of, either the Company or the Optionee
             (that is the functional  currency of the Company or the currency in
             which the Option is paid) as determined by the Company.

9.   ADJUSTMENTS

     Upon the occurrence of any of the following  described  events,  Optionee's
     rights to purchase  Shares  under the ISOP shall be  adjusted as  hereafter
     provided:

     9.1     In  the  event  of  Transaction,   the  unexercised   Options  then
             outstanding  under the ISOP may be  assumed or  substituted  for an
             appropriate  number  of  shares  of each  class of  shares or other
             securities of the  Successor  Company (or a parent or subsidiary of
             the Successor  Company) as were  distributed to the shareholders of
             the Company in connection with the Transaction. In the case of such
             assumption and/or substitution of Options,  appropriate adjustments
             shall be made to the  Purchase  Price so as to reflect such action,
             all as subject to the  determination of the Committee or the Board,
             which determination shall be in their sole discretion and final. In
             the  event  the  Successor  Company  does not  agree to  assume  or
             substitute  as described  in this  Section  9.1, the Options  shall
             terminate as of the date of the closing of the Transaction.

     9.2     Notwithstanding  the above and subject to any  applicable  law, the
             Board or the  Committee  shall  have full  power and  authority  to
             determine that in certain Option Agreements there shall be a clause
             instructing  that,  if in any  such  Transaction  as  described  in
             section 9.1 above,  the Successor  Company (or parent or subsidiary
             of the  Successor  Company)  does not agree to assume or substitute
             for the Options, the Vesting Dates shall be accelerated so that any
             unvested Option or any portion thereof shall be immediately  vested
             as of the date which is ten (10) days prior to the  effective  date
             of the Transaction.

     9.3     For  the  purposes  of  section  9.1  above,  an  Option  shall  be
             considered  assumed or substituted if,  following the  Transaction,
             the Option confers the right to purchase or receive, for each Share
             underlying  an Option  immediately  prior to the  Transaction,  the
             consideration  (whether shares,  options, cash, or other securities
             or property)  received in the Transaction by holders of shares 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 Transaction is
             not solely ordinary  shares (or their  equivalent) of the Successor
             Company or its parent or  subsidiary,  the Committee  may, with the
             consent of the Successor Company,  provide for the consideration to
             be received  upon the exercise of the Option to be solely  ordinary
             shares (or their equivalent) of the Successor Company or its parent
             or  subsidiary  equal  in  Fair  Market  Value  to  the  per  Share
             consideration  received by holders of a majority of the outstanding
             shares in the Transaction;  and provided further that the Committee
             may determine,  in its discretion,  that in lieu of such assumption
             or substitution of Options for options of the Successor  Company or
             its parent or subsidiary,  such Options will be substituted for any
             other type of asset or property  including cash which is fair under
             the circumstances.

                                       10


                                       11

     9.4     In the  event  of a  proposed  liquidation  or  dissolution  of the
             Company, the Company shall notify all unexercised Option holders at
             least  fifteen  (15) days prior to such  action.  To the extent not
             previously exercised the Options shall terminate  immediately prior
             to the consummation of such proposed action.

     9.5     If the  outstanding  shares  of the  Company  shall  at any time be
             changed or  exchanged by  declaration  of a share  dividend  (bonus
             shares),   share   split,   combination   or  exchange  of  shares,
             recapitalization, or any other like event by or of the Company, and
             as often as the same shall occur,  then the number,  class and kind
             of the  Shares  subject  to the  ISOP  or  subject  to any  Options
             therefore granted,  and the Purchase Prices, shall be appropriately
             and equitably  adjusted so as to maintain the proportionate  number
             of Shares without changing the aggregate Purchase Price,  provided,
             however,  that  no  adjustment  shall  be  made  by  reason  of the
             distribution   of   subscription   rights   (rights   offering)  on
             outstanding  shares.  Upon happening of any of the  foregoing,  the
             class and aggregate number of Shares issuable  pursuant to the ISOP
             (as set forth in  Section 7 hereof),  in  respect of which  Options
             have not yet been exercised,  shall be appropriately  adjusted, all
             as will be  determined  by the Board whose  determination  shall be
             final.

10.  TERM AND EXERCISE OF OPTIONS

     10.1    Options shall be exercised by the Optionee by giving written notice
             to the Company and/or to any third party  designated by the Company
             (the  "Representative"),   in  such  form  and  method  as  may  be
             determined  by the Company and when  applicable,  by the Trustee in
             accordance  with the  requirements  of Section 102,  which exercise
             shall be  effective  upon  receipt  of such  notice by the  Company
             and/or the  Representative and the payment of the Purchase Price at
             the Company's or the Representative's  principal office. The notice
             shall specify the number of Shares with respect to which the Option
             is being exercised.

     10.2    Each Option granted under this ISOP shall be exercisable  following
             the Vesting Dates and for the number of Shares as shall be provided
             in Exhibit B to the Option  Agreement.  Options,  to the extent not
             previously  exercised,  shall terminate  forthwith upon the earlier
             of:  (i) the date set forth in the Option  Agreement;  and (ii) the
             expiration of any extended period in any of the events set forth in
             section 10.5 below.

     10.3    The Options may be  exercised  by the Optionee in whole at any time
             or in part from time to time, to the extent that the Options become
             vested and exercisable,  prior to the Expiration Date, and provided
             that, subject to the provisions of section 10.5 below, the Optionee
             is employed by or  providing  services to the Company or any of its
             Affiliates,  at all times  during  the  period  beginning  with the
             granting of the Option and ending upon the date of exercise.

     10.4    Subject to the  provisions  of section 10.5 below,  in the event of
             termination of Optionee's employment or services,  with the Company
             or any of its Affiliates, all Options granted to such Optionee will
             immediately  expire.  A notice  of  termination  of  employment  or
             service shall be deemed to constitute  termination of employment or
             service. For the avoidance of doubt, in case of such termination of
             employment  or  service,  the  unvested  portion of the  Optionee's
             Option shall not vest and shall not become exercisable.

                                       11


                                       12

     10.5    Notwithstanding  anything to the  contrary  hereinabove  and unless
             otherwise determined in the Optionee's Option Agreement,  an Option
             may be  exercised  after  the  date of  termination  of  Optionee's
             employment or service with the Company or any Affiliates  during an
             additional period of time beyond the date of such termination,  but
             only with  respect to the  number of Vested  Options at the time of
             such termination according to the Vesting Dates, if:

             (i)    termination  is  without  Cause,  in which  event any Vested
                    Option still in force and unexpired may be exercised  within
                    a  period  of  ninety  (90)  days  after  the  date  of such
                    termination; or-

             (ii)   termination  is the  result  of death or  disability  of the
                    Optionee,  in which event any Vested  Option  still in force
                    and  unexpired  may be  exercised  within a period of ninety
                    (90) days after the date of such termination; or -

             (iii)  the Committee  shall  authorize an extension of the terms of
                    all or part of the  Vested  Options  beyond the date of such
                    termination  for a period not to exceed  the  period  during
                    which the Options by their terms would  otherwise  have been
                    exercisable.

             For avoidance of any doubt, if termination of employment or service
             is for Cause, any outstanding unexercised Option (whether vested or
             non-vested),   will  immediately  expire  and  terminate,  and  the
             Optionee shall not have any right in connection to such outstanding
             Options.

     10.6    To avoid doubt,  the Optionees  shall not have any of the rights or
             privileges of  shareholders of the Company in respect of any Shares
             purchasable  upon the  exercise  of any  Option,  nor shall they be
             deemed to be a class of  shareholders  or  creditors of the Company
             for  purpose  of the  operation  of  sections  350  and  351 of the
             Companies Law or any successor to such section,  until registration
             of the Optionee as holder of such Shares in the Company's  register
             of shareholders  upon exercise of the Option in accordance with the
             provisions  of the ISOP,  but in case of Options and Shares held by
             the Trustee, subject to the provisions of Section 6 of the ISOP.

     10.7    Any form of Option  Agreement  authorized  by the ISOP may  contain
             such other provisions as the Committee may, from time to time, deem
             advisable.

     10.8    With respect to Unapproved 102 Option, if the Optionee ceases to be
             employed by the Company or any Affiliate, the Optionee shall extend
             to the Company and/or its Affiliate a security or guarantee for the
             payment of tax due at the time of sale of Shares, all in accordance
             with the  provisions  of Section 102 and the rules,  regulation  or
             orders promulgated thereunder.

11.  VESTING OF OPTIONS

     11.1    Unless  Exhibit  B to  the  Option  Agreement  provides  otherwise,
             one-fourth  (1/4) of the Options  shall vest (i.e.,  options  shall
             become  exercisable)  at the end of the first year of an Optionee's
             continuous  services or employment  with the group,  and one thirty
             sixth (1/36) of the remaining  Options shall vest per month of such


                                       12

                                       13

             continuous employment over the next thirty six months.  However, no
             Option shall be exercisable after the Expiration Date.

     11.2    An Option may be subject to such other terms and  conditions on the
             time or times when it may be  exercised,  as the Committee may deem
             appropriate. The vesting provisions of individual Options may vary.

12.  PURCHASE FOR INVESTMENT

     The Company's  obligation  to issue or allocate  Shares upon exercise of an
     Option  granted  under  the ISOP is  expressly  conditioned  upon:  (a) the
     Company's  completion of any registration or other  qualifications  of such
     Shares  under  all   applicable   laws,   rules  and   regulations  or  (b)
     representations   and   undertakings   by  the   Optionee   (or  his  legal
     representative,  heir or legatee,  in the event of the Optionee's death) to
     assure that the sale of the Shares complies with any registration exemption
     requirements   which  the  Company  in  its  sole  discretion   shall  deem
     appropriate.  Such required  representations  and  undertakings may include
     representations   and   agreements   that  such   Optionee  (or  his  legal
     representative,  heir,  or  legatee):  (a) is  purchasing  such  Shares for
     investment  and not with any  present  intention  of selling  or  otherwise
     disposing thereof;  and (b) agrees to have placed upon the face and reverse
     of any  certificates  evidencing such Shares a legend setting forth (i) any
     representations  and  undertakings  which  such  Optionee  has given to the
     Company or a reference  thereto and (ii) that,  prior to effecting any sale
     or other  disposition of any such Shares,  the Optionee must furnish to the
     Company an opinion of counsel,  satisfactory to the Company, that such sale
     or  disposition   will  not  violate  the  applicable   laws,   rules,  and
     regulations,  whether of the State of Israel or of the United States or any
     other State having jurisdiction over the Company and the Optionee.


13.  DIVIDENDS

     as creating any  limitations  on the power of the Board to adopt such other
     incentive  arrangements  as  it  may  deem  desirable,  including,  without
     limitation, the granting of Options otherwise than under the ISOP, and such
     arrangements may be either applicable generally or only in specific cases.

     The terms of each Option may differ from other  Options  granted  under the
     ISOP at the same time, or at any other time.  The Board may also grant more
     than one Option to a given Optionee during the term of the ISOP,  either in
     addition to, or in substitution for, one or more Options previously granted
     to that Optionee.
