Gross Salary shall be increased by ten percent (10%). This newly increased
Yearly Gross Salary shall be payable in accordance with the provisions of
sub-section (a) above and the other sub-sections of this Section 4.

      (a2) Following the 2nd Financing Round, at the end of each year of

Gross Salary. Any changes in Employee's Yearly Gross Salary after such 2nd
Financing Round shall be in the sole discretion of the Company's Board of
Directors. When reviewing the Employee's Yearly Gross Salary, the Board of
Directors shall take into account the following considerations: (i) the
Company's financial situation and profitability; (ii) whether or not the
Employee performed his duties hereunder to the Company's satisfaction and in
accordance with his projections and reports to the Company, and those other
considerations as may be appropriate in the circumstances. For the removal of
doubt, for as long as the Employee is a member of the Company's Board of
Directors, any change in the Employee's Yearly Gross Salary as aforesaid and any
other changes to the terms of employment hereunder, shall require the approval
of the Company's shareholders, all in accordance with the provisions of the

any other agency or entity in respect of such periods.

(13.333%) of each Monthly Gross Salary payment (out of which 8.33% are
designated for severance payments and 5% are designated for premium payments)
(the "COMPANY CONTRIBUTION") and the Employee shall contribute five percent (5%)
of the Monthly Gross Salary payment (the "EMPLOYEE'S CONTRIBUTION") toward the
premiums payable in respect of such insurance, all amounts in the aggregate not
to exceed the Monthly

                                       3
<PAGE>

Gross Salary of Employee (the "INSURANCE POLICY"). The Employee hereby instructs
the Company to make the necessary transfers to the insurance company of the
amounts representing the Employee's and the Company's Contributions on account
of the Insurance Policy.

      (II) It is hereby agreed that, should the Employee be or become entitled
to severance pay under any applicable Israeli law, the amounts accrued in the
Insurance Policy on account of that portion of the Company's Contribution which
is designated for severance pay, [i.e., the 8.33%] (the "SEVERANCE PORTION")
shall be in lieu thereof and in full and final substitution therefor.

      Notwithstanding subsection (c)(II) above, if the Severance Portion accrued
in the Insurance Policy is less than the amount of severance pay the Employee is
or will be entitled to under applicable Israeli law, then the Company shall pay
the Employee the difference thereof.

      (III) It is hereby agreed that upon termination of employment under this
Agreement, the Company shall release to the Employee all amounts accrued in the
Insurance Policy on account of both the Company's and Employee's Contributions.

      Notwithstanding subsection (c)(III) above, the Company will not be
obligated to release to the Employee the Severance Portion of the Insurance
Policy, or pay the Employee any other form of severance pay, under any one of
the following circumstances:

            (xx) Termination of employment by the Company for `cause' (as
      defined in Section 3(c) above); and

            (yy) Termination of employment for reasons which under Israeli law
      would deprive the Employee of rights to severance pay.

      (d) The Company and the Employee shall open and maintain a Keren
Hishtalmut Fund (the "FUND") for the benefit of the Employee. The Company shall
contribute to the Fund an amount equal to 7.5% of each Monthly Gross Salary
payment and the Employee shall contribute to such Fund 2.5% of each Monthly
Gross Salary payment. It is hereby clarified, that any tax liabilities that are
due on account of the Company's contribution to the Fund shall be born solely by
the Employee. The Employee hereby instructs Company to make the necessary
transfers to the Fund of the amounts representing both the Employee's and the
Company's contributions.

      (d1) The Company shall obtain Disability Insurance ("Ovdan Kosher Avoda"),
which may be included within the Insurance Policy, for the exclusive benefit of
the Employee and shall contribute therefor an amount up to two and a half
percent (2.5%) of each Monthly Gross Salary payment.

      (e) Bonus. The Company's board of directors shall in its sole discretion,
determine the amount of any bonus, the method of its computation, the periods
for which any such bonus shall be paid and the performance targets required to
be achieved by the

                                       4
<PAGE>

Employee prior to receipt of any such bonus. When determining the amount of
bonus to be paid hereunder, the Company's board or directors shall also consider
factors such as the Company's financial condition and the Employee's achievement
of any of the targets set by the Company's Board of Directors.

entitled to fifteen (15) working days of paid vacation.

days and so on), up to a maximum aggregate of twenty-one (21) working days of
paid vacation for any given year of employment hereunder.

      (c) Vacation time may be taken at times subject to the reasonable approval
of the Company and may be accumulated for no more than thirty (30) days for a
period of two (2) years after which time Employee shall forfeit any unused
vacation remaining at the end of such two year period.

      (d) Accumulated vacation time shall be paid according to the regular
payroll practice in Company, only upon termination of the employment by Company.

of a make, model and size as determined by the Company in its sole discretion.
Notwithstanding the foregoing, the car provided shall be a category 3 car. The
Company shall pay all actual maintenance (including gasoline) and insurance
expenses in connection with the automobile and its use by the Employee. For the
removal of doubt, the Company shall only be required to provide said insurance
in connection with the use of such automobile solely by the Employee. The
Company shall bear the cost of the taxes payable in connection with the
provision of such automobile and the use of same by the Employee. For the

harmless the Company, its officers, directors and employees (the "INDEMNIFIED

            (b) If at any time after the second anniversary but before the third
            anniversary of the Effective Date of the Employment Agreement I am
            no longer an employee of the Company, except for Termination Without
            Cause, then 120,000 of my Shares shall be transferred to the
            Repurchaser for no consideration; and

            (c) If at any time after the third anniversary but before the fourth
            anniversary of the Effective Date of the Employment Agreement I am
            no longer an employee of the Company, except for Termination Without
            Cause, then 60,000 of my Shares shall be transferred to the
            Repurchaser for no consideration; and

            (d) If on the fourth anniversary of the Effective Date of the
            Employment Agreement I am still an employee of the Company then the
            Repurchaser shall no longer be entitled to receive by way of
            transfer any portion of my Shares and if the Repurchaser is the
            Company, then it shall not be entitled to a reversion back to it of
            any portion of the Shares.

      The "REPURCHASER" shall mean the Company, if it so desires and to the
      extent it is permitted by law. Otherwise, Repurchaser shall mean such
      entity designated by the Company which shall hold such repurchased shares
      in escrow for future allocation to employees, directors and other service
      providers of the Company and/or any subsidiary thereof, under an approved
      Share Option Plan(s).

2.

            (a) In order to facilitate the repurchase and/or transfer of the
            shares as set forth above in an orderly fashion, I shall,
            simultaneously with the execution of this Undertaking, execute three
            (3) deeds of transfer of shares, in the form attached hereto as
            EXHIBIT A (the "DEEDS OF TRANSFER"). With these Deeds of Transfer I
            hereby irrevocably authorize the Company or any designee thereof to
            fill in the name of the transferee in these Deeds and to complete
            the transfer of Shares according thereto.

<PAGE>
                                       2

            (b) The number of Shares in each Deed of Transfer, during the period
            in which the Deeds of Transfer are held by KH, shall be subject to
            automatic adjustment (the "AUTOMATIC ADJUSTMENT") if the outstanding
            shares of the Company shall be changed or exchanged by declaration
            of a share dividend, share split, combination or exchange of shares,
            recapitalization, extraordinary dividend payable in shares of a
            corporation other than the Company, or otherwise in cash, or any
            other like event by or of the Company, and requiring that the
            number, class and kind of the Shares be adjusted (each an
            "ADJUSTMENT EVENT"). The mechanics of the Automatic Adjustment shall
            be as follows: if after the occurrence of an Adjustment Event any
            Deed(s) of Transfer shall be released to the Repurchaser according
            to the provisions of Section 1 above and the terms of the Escrow
            Agreement annexed hereto as EXHIBIT B, then the number of Shares
            that shall be transferred pursuant thereto shall be the number
            appearing in the Deed(s) of Transfer as adjusted to the Adjustment
            Event.

            (c) Becker hereby acknowledges and agrees that upon receipt of
            notice from the Company that an Adjustment Event has occurred, the
            Automatic Adjustment mechanism will operate, and that if the
            Repurchaser shall become entitled to any portion of the Shares
            following such Adjustment Event, then the Deed(s) of Transfer shall
            be deemed to cover the number of Shares stated therein as adjusted
            to such Adjustment Event.

            (d) Becker hereby further acknowledges and confirms that the
            Repurchaser shall be entitled to rely upon the Deed(s) of Transfer
            with the number of Shares as adjusted to an Adjustment Event. Becker
            agrees that the corporate records of the Company shall be conclusive
            evidence of an occurrence of any such Adjustment Event.

3.

            (a) The Deeds of Transfer shall be held in trust by K.H. Trustees
            Ltd., ("KH"). Upon receipt of notice from the Company of the
            occurrence of an event of termination of my employment, all in
            accordance with the provisions of Sections 1(a) through 1(c) above
            (the "COMPANY's INSTRUCTIONS NOTICE"), K.H. shall, within 3 business
            days of such notice, send me a copy of the Company's Instructions
            Notice ("KH's NOTICE"). Within 4 business days from the date of KH's
            Notice, KH shall release to the Company the applicable number of
            Deeds of Transfer (as adjusted to an Adjustment Event). The
            Company's Instructions Notice shall be final and binding upon KH or
            any successor thereof, unless I provide KH with an appropriate
            injuctive order, preventing such release to the Company, issued by a
            court of competent jurisdiction prior to the end of such 4 days'
            period.

            (b) Following the second anniversary of the Effective Date of the
            Employment Agreement, upon my written request to KH accompanied with
            a letter of confirmation from the Company to the effect that until
            such anniversary I was an employee of the Company, KH shall release
            one (1) Deed of Transfer (as adjusted to an Adjustment Event) to my
            possession.

            (c) Following the third anniversary of the Effective Date of the
            Employment Agreement, upon my written request to KH accompanied with
            a letter of confirmation from the Company to the effect that until
            such anniversary I was an employee of the Company, KH shall release
            one (1) Deed of Transfer (as adjusted to an Adjustment Event) to my
            possession, or two (2) such Deeds of Transfer (as adjusted to an
            Adjustment Event), provided however, that I did not previously
            request a release under sub-section (b) above.

<PAGE>
                                       3

            (d) Upon the fulfillment of the condition set forth in Section 1(d)
            above and upon my written request accompanied by a written
            confirmation by the Company to the effect that on the fourth
            anniversary of the Effective Date of the Employment Agreement I was
            an employee of the Company, KH shall return all three (3) Deeds of
            Transfer (as adjusted to an Adjustment Event) to my possession,
            provided however, that I did not previously request a release under
            sub-sections (b) and/or (c) above.

            (e) Upon my written request accompanied with a written confirmation
            from the Company to the effect that: (i) one of the events described
            in Sections 9.1 through 9.6 has occurred; and (ii) that until the
            occurrence of such event I was an employee of the Company, KH shall
            release to my possession any remaining Deeds of Transfer (as
            adjusted to an Adjustment Event) and that portion of my Shares shall
            no longer be subject to the repurchase or reversion right of the
            Repurchaser.

            (f) Upon the written request of the executor of my estate
            accompanied with: (i) a notarized copy of a death certificate issued
            upon my death; and (ii) a written confirmation from the Company to
            the effect that until my death I was an employee of the Company, KH
            shall release to the possession of such executor any remaining Deeds
            of Transfer (as adjusted to an Adjustment Event).

4.    The Ordinary Shares that may be repurchased according to the provisions of
      this Undertaking shall confer upon their holder those rights attached to
      the Ordinary Shares of the Company, as set forth in the Company's Articles
      of Association as may be in effect from time to time.

5.    In order to comply with the provisions of this Undertaking, with the
      exception of transfer of the Shares that are no longer subject to
      repurchase, I further undertake the following in addition to any other
      restrictions on the my Shares in any other agreements and/or documents:

            (a) Until the lapse of one (1) year following the Effective Date of
            the Employment Agreement, I shall not transfer, undertake to
            transfer, otherwise dispose of, pledge, charge or otherwise encumber
            (hereinafter a "DISPOSITION") 180,000 of my Shares (as adjusted an
            Adjustment Event); and

            (b) After the period set forth in sub-section (a) above and until
            the lapse of two (2) years following the Effective Date of the
            Employment Agreement, I shall not cause a Disposition of 120,000 of
            my Shares (as adjusted to an Adjustment Event); and

            (c) After the period set forth in sub-section (b) above and until
            the lapse of three (3) years following the Effective Date of the
            Employment Agreement, I shall not cause a Disposition of 60,000 of
            my Shares (as adjusted to an Adjustment Event).

            (d) I hereby further acknowledge and expressly agree that the share
            certificate(s) corresponding to the Shares (including any share
            certificate to be issued instead of or in addition to such shares as
            detailed in Section 3 above) may bear a legend indicating that such
            shares are subject to the restrictions provided for hereunder (the
            "RESTRICTIVE LEGEND"). Following the actual release to my possession
            of the Deeds of Transfer or any one of them, as applicable, upon
            delivery to the Company of my written request, I shall be entitled
            to have the Restrictive Legend removed from the share certificate
            issued to me by the Company, with respect to those Shares no longer
            subject to the repurchase right herein. In order to accomplish this
            I shall surrender my share certificate to the Company for its
            replacement with a new share certificate(s), not bearing the
            Restrictive Legend. Notwithstanding the foregoing, the new share
            certificate(s) will continue to bear the following legend:

<PAGE>
                                       4

      "The Shares represented by this certificate, have not been registered
      under the Securities Act of 1933 or under the securities laws of any
      state. These shares have been acquired for investment and not with a view
      to distribution or resale, and may not be sold, transferred, pledged or
      hypothecated in the absence of an effective registration statement for
      such shares under the Securities Act of 1933 and such state securities
      laws as maybe applicable or the delivery to BIO-IT (BIO INFORMATION
      TECHNOLOGIES) LTD. of an opinion of counsel, reasonably acceptable to it,
      to the effect that registration is not required under such Act or such
      state securities laws.

      The foregoing restrictions terminate when the shares may be freely
      transferred without restriction under Rule 144, under the Securities Act
      of 1933, or any successor thereto, and may be disregarded thereafter.

      The sale or transfer of the securities represented by this certificate is
      subject to the terms and conditions of a certain Shareholders Agreement
      dated _____________ and certain schedules thereto, by and among the holder
      hereof and other shareholders of the Company. Copies of such agreement and
      schedules may be obtained upon written request to the Company's
      Secretary".

6.    I hereby represent and warrant to the Repurchaser that the portion of the
      Shares subject to repurchase in accordance with this Undertaking, when
      transferred to the Repurchaser shall be free of any lien, encumbrance
      and/or any right or obligation which may limit the right of the
      Repurchaser in such Shares.

7.    Notwithstanding the above, I reserve the right to transfer any portion of
      my Shares to a Permitted Transferee (as such term is defined in the
      Company's Articles of Association, as same may be amended from time to
      time), provided that any such transferee shall undertake, in writing, to
      fully comply with the provisions of this Undertaking, and shall, upon such
      transfer to such transferee and as a condition precedent to its validity,
      execute appropriate Deed(s) of Transfer, mutatis mutandis.

8.    I hereby agree that I shall have no rights of a shareholder or otherwise
      have any rights with respect to those Shares that have been repurchased,
      or if the Repurchaser is the Company, then with respect to the Shares that
      have reverted back to the Company, all in accordance with the provisions
      set forth above. Subject to the restrictions appearing in this
      undertaking, the Company's Articles of Association, or any other agreement
      to which I am a party, I reserve all rights of a shareholder of the
      Company with respect to those Shares that have not been repurchased or
      have not reverted back to the Company, as applicable.

9.    Notwithstanding anything to the contrary herein, upon the occurrence of
      any one of the following events prior to the end of the Term of Service
      and provided that until the occurrence of any such event I am an employee
      of the Company, the Shares shall no longer be subject to the
      repurchase/reversion provisions set forth above and the Repurchaser or the
      Company, as applicable, shall thereafter have no right to have such Shares
      revert back or transferred to it:

                                       5

      9.1   upon the consummation of a merger of the Company into another entity
            where the Company is not the surviving entity of the merger
            transaction;

      9.2   upon the consummation of an acquisition of all or substantially all
            of the Company's assets;

      9.3   upon the consummation of an acquisition of all or substantially all
            of the Company's securities, except where the acquirer is at the
            time of such acquisition a 25% or more shareholder in the Company;

      9.4   upon my disability as such term is defined in the Employment
            Agreement;

      9.5   upon the consummation of the Company's initial public offering of
            its securities to the public; and

      9.6   upon Termination Without Cause; and

      9.7   upon my death.

10.   In connection with the deposit of the Deeds of Transfer with KH, both the
      Company and myself will execute a form of escrow agreement with KH, in the
      form attached hereto as EXHIBIT B (the "ESCROW AGREEMENT"). The Escrow
      Agreement shall be executed simultaneously with the execution of this
      Undertaking.

IN WITNESS WHEREOF, I have executed this undertaking as of October 31, 2000.

WHEREAS Becker and the Company intend that the Trustee hold certain deeds of

NOW THEREFORE, in consideration of the undertakings and premises herein, the
parties hereto hereby agree as follows:

1.    GENERAL

All terms not defined herein shall have the meanings ascribed to them in the
Undertaking to which this Agreement constitutes an exhibit (the "UNDERTAKING")
or the Employment Agreement between Becker and the Company dated as of October
31, 2000 (the "EMPLOYMENT AGREEMENT").

2.    ESCROW AND RELEASE FROM ESCROW

      2.1   By execution of this Escrow Agreement, the Company and Becker, and
            their respective successors and assigns, hereby irrevocably appoint
            the Trustee to act in accordance with the provisions of this
            Agreement.

      2.2   Simultaneously with the execution of this Agreement, Becker shall
            execute three Deeds of Transfer of shares in accordance with the
            provisions of the Undertaking. Immediately following their
            execution, Becker shall deposit these Deeds of Transfer with the
            Trustee to be held in escrow until their release in accordance with
            the provisions of the Undertaking and this Agreement.

      2.3

            (a) Upon the receipt of written notice from the Company of
            occurrence of any one of the events described in Sections 1(a)
            through I (c) of the Undertaking (the "COMPANY'S INSTRUCTIONS
            NOTICE") the Trustee shall, within three (3) business days of such
            notice, send Becker a copy of the Company's Instructions Notice (the
            "TRUSTEE'S NOTICE"). Within four (4) business days from the date of
            the Trustee's Notice, Becker hereby irrevocably instructs the
            Trustee to release to Company Deed(s) of Transfer as follows, unless
            prior to end of such 4 days' period Becker provides the Trustee
            (with a copy to the Company) of an appropriate injuctive order
            preventing such release, issued by a court of competent
            jurisdiction:

            (i) If said notice is issued in connection with Section 1(a) of the

            Event).

            Ordinary Shares of the Company (as adjusted to an Adjustment Event).

            Ordinary Shares of the Company (as adjusted to an Adjustment Event).

            (b) Unless the Deed(s) of Transfer have been released to the Company
            in accordance with the provisions of the Undertaking or sub-section
            (a) above, the Trustee may release the Deed(s) of Transfer to
            Becker's possession in accordance with the following provisions:

            (i) Following the second anniversary of the Effective Date of the
            Employment Agreement, upon receipt of Becker's written request
            accompanied by a letter of confirmation from the Company to the
            effect that Becker was employed by the Company on such anniversary,
            the Trustee shall release to Becker one (1) Deed of Transfer.

            (ii) Following the third anniversary of the Effective Date of the
            Employment Agreement, upon receipt of Becker's written request
            accompanied by a letter of confirmation from the Company to the
            effect that Becker was employed by the Company on such anniversary,
            the Trustee shall release to Becker one (1) Deed of Transfer, or two
            (2) Deeds of Transfer, provided however, that Becker did not
            previously request a release under sub-section (b)(i) above.

            (c) Upon receipt of a written request from Becker accompanied by a
            written confirmation from the Company to the effect that on the

            Becker was an employee of the Company, the Trustee shall release all
            three (3) Deeds of Transfer to Becker's possession, provided
            however, that Becker did not previously request a release under
            sub-sections (b)(i) and/or (b)(ii) above.

            (d) Upon receipt from Becker of a written request accompanied by a

            the events described in Sections 9.1 through 9.6 of the Undertaking
            has occurred; and (ii) that until the occurrence of any such event
            Becker was an Employee of the Company, the Trustee shall release to

            (e) Upon the written request of the executor of Becker's estate
            accompanied with: (i) a notarized copy of a death certificate issued

            this Escrow Agreement, the Trustee shall be entitled to rely on such
            notice and that the Automatic Adjustment mechanism shall become

TO: BIO-IT (BIO INFORMATION TECHNOLOGIES) LTD. ANNEX 4

FROM: DR. OREN BECKER                                        DATE: April 3, 2001

                               AMENDED UNDERTAKING

1.    I, the undersigned, hereby agree and undertake to subject the 240,000
      Ordinary Shares (the "SHARES") I hold in Bio-IT (Bio Information
      Technologies, Ltd. (the "COMPANY") to my continued services to the Company
      as an employee, such that if I do not complete four (4) years of service
      (the "TERM OF SERVICE") portions of my Shares will revert back to the
      Company or be transferred to the Repurchaser (as defined below), as
      applicable, according to the following provisions:

      (a)   If at any time prior to the second anniversary of the Effective Date
            as defined in the Employment Agreement entered into between myself
            and the Company on October 31, 2000 (the "ORIGINAL EMPLOYMENT
            AGREEMENT"), as amended on April 3, 2001 (the "AMENDMENT" and
            together with the Original Employment Agreement, the "EMPLOYMENT
            AGREEMENT") I am no longer an employee of the Company, except for
            termination of my services by the Company without cause (as such
            term is defined in the Employment Agreement) ("TERMINATION WITHOUT
            CAUSE") then 180,000 of my Shares shall be transferred to the
            Repurchaser, as defined below, for no consideration; and

      (b)   If at any time after the second anniversary but before the fourth
            anniversary of the Effective Date of the Employment Agreement I am
            no longer an employee of the Company, except for Termination Without
            Cause, then for each three month period remaining between the date
            on which I cease to be an employee of the Company and the fourth
            anniversary of the Effective Date of the Employment Agreement 15,000
            of my Shares shall be transferred to the Repurchaser for no
            consideration; and

      (c)   [intentionally deleted]; and

      (d)   If on the fourth anniversary of the Effective Date of the Employment
            Agreement I am still an employee of the Company then the Repurchaser
            shall no longer be entitled to receive by way of transfer any
            portion of my Shares and if the Repurchaser is the Company, then it
            shall not be entitled to a reversion back to it of any portion of
            the Shares.

      The "REPURCHASER" shall mean the Company, if it so desires and to the
extent it is permitted by law. Otherwise, Repurchaser shall mean such entity
designated by the Company which shall hold such repurchased shares in escrow for
future allocation to employees, directors and other service providers of the
Company and/or any subsidiary thereof, under an approved Share Option Plan(s).

                                       5

2.    (a) In order to facilitate the repurchase and/or transfer of the shares as
      set forth above in an ordinary fashion, I shall, simultaneously with the
      execution of this Amended Undertaking, confirm that two (2) deeds of
      transfer of shares, in the form attached hereto as EXHIBIT A (the "DEEDS
      OF TRANSFER") executed by me in connection with Sections 1(b) (for 120,000
      Shares) and 1(c) (for 60,000 Shares) of the original Undertaking were
      returned to me marked cancelled; and that I executed eight (8) new Deeds
      of Transfer (each for 15,000 Shares) in connection with Section 1(b) of
      this Amended Undertaking. With these Deeds of Transfer I hereby
      irrevocably authorize the Company or any designee thereof to fill in the
      name of the transferee in these Deeds and to complete the transfer of
      Shares according thereto.

      (b) The number of Shares in each Deed of Transfer, during the period in
      which the Deeds of Transfer are held by KH, shall be subject to automatic
      adjustment (the "AUTOMATIC ADJUSTMENT") if the outstanding shares of the
      Company shall be changed or exchanged by declaration of a share dividend,
      share split, combination or exchange of shares, recapitalization,
      extraordinary dividend payable in shares of a corporation other than the
      Company, or otherwise in cash, or any other like event by or of the
      Company, and requiring that the number, class and kind of the Shares be
      adjusted (each an "ADJUSTMENT EVENT"). The mechanics of the Automatic
      Adjustment shall be as follows: if after the occurrence of an Adjustment
      Event any Deed(s) of Transfer shall be released to the Repurchaser
      according to the provisions of Section 1 above and the terms of the
      Amended Escrow Agreement annexed to the Amendment as ANNEX 5, then the
      number of Shares that shall be transferred pursuant thereto shall be the
      number appearing in the Deed(s) of Transfer as adjusted to the Adjustment
      Event.

      (c) Becker hereby acknowledges and agrees that upon receipt of notice from
      the Company that an Adjustment Event has occurred, the Automatic
      Adjustment mechanism will operate, and that if the Repurchaser shall
      become entitled to any portion of the Shares following such Adjustment
      Event, then the Deed(s) of Transfer shall be deemed to cover the number of
      Shares stated therein as adjusted to such Adjustment Event.

      (d) Becker hereby further acknowledges and confirms that the Repurchaser
      shall be entitled to rely upon the Deed(s) of Transfer with the number of
      Shares as adjusted to an Adjustment Event, Becker agrees that the
      corporate records of the Company shall be conclusive evidence of an
      occurrence of any such Adjustment Event.

3.    (a) The Deeds of Transfer shall be held in trust by K.H. Trustees Ltd.,
      ("KH"). Upon receipt of notice from the Company of the occurrence of an
      event of termination above (the "COMPANY'S INSTRUCTIONS NOTICE"), K.H.
      shall, within 3 business days of such notice, send me a copy of the
      Company's Instructions Notice ("KH's NOTICE"). Within 4 business days from
      the date of KH's Notice, KH shall release to the Company the applicable
      number of Deeds of Transfer (as adjusted to an Adjustment Event). The
      Company's Instructions Notice shall be

<PAGE>

                                       6

      final and binding upon KH or any successor thereof, unless I provide KH
      with an appropriate injunctive order, preventing such release to the
      Company, issued by a court of competent jurisdiction prior to the end of
      such 4 days' period.

      (b) Following the second anniversary of the Effective Date of the
      Employment Agreement, upon my written request to KH accompanied with a
      letter of confirmation from the Company to the effect that until such
      anniversary I was an employee of the Company, KH shall release the first
      Deed of Transfer (for 180,000 Shares as adjusted to an Adjustment Event)
      to my possession.

      (c) Following the second anniversary of the Effective Date of the
      Employment Agreement, upon my written request to KH accompanied with a
      letter of confirmation from the Company to the effect that following such
      anniversary I was an employee of the Company for a successive period of
      three (3) months or any successive three (3) month period thereafter
      (i.e., three (3), six (6), nine (9), twelve (12), fifteen (15), eighteen
      (18), twenty-one (21) and/or twenty-four (24) months after the second
      anniversary of the Effective Date of the Employment Agreement), KH shall
      release one (1) Deed of Transfer (for 15,000 Shares as adjusted to an
      Adjustment Event) for each such three month period to my possession, as
      well as the first Deed of Transfer (for 180,000 Shares as adjusted to an
      Adjustment Event, provided however, that I did not previously request a
      release under the sub-section (b) above.

      (d) Upon the fulfillment of the condition set forth in Section 1(d) above
      and upon my written request accompanied by a written confirmation by the
      Company to the effect that on the fourth anniversary of the Effective Date
      of the Employment Agreement I was an employee of the Company, KH shall
      return all nine (9) Deeds of Transfer (as adjusted to an Adjustment Event)
      to my possession, provided however, that I did not previously request a
      release under sub-sections (b) and/or (c) above.

      (e) Upon my written request accompanied with a written confirmation from
      the Company to the effect that: (i) one of the events described in
      Sections 9.1 through 9.6 has occurred; and (ii) that until the occurrence
      of such event I was an employee of the Company, KH shall release to my
      possession any remaining Deeds of Transfer (as adjusted to an Adjustment
      Event) and that portion of my Shares shall no longer be subject to the
      repurchase or reversion right of the Repurchaser.

      (f) Upon the written request of the executor of my estate accompanied
      with: (i) a notarized copy of a death certificate issued upon my death;
      and (ii) written confirmation from the Company to the effect that until my
      death I was an employee of the Company, KH shall release to the possession
      of such executor any remaining Deeds of Transfer (as adjusted to an
      Adjustment Event).

4.    The Ordinary Shares that may be repurchased according to the provisions of
      this Undertaking shall confer upon their holder those rights attached to
      the Ordinary

<PAGE>

                                       7

      Shares of the Company, as set forth in the Company's Articles of
      Association as may be in effect from time to time.

5.    In order to comply with the provisions of this Undertaking, with the
      exception of transfer of the Shares that are no longer subject to
      repurchase, I further undertake the following in addition to any other
      restrictions on the my Shares in any other agreements and/or documents:

      (a)   Until the lapse of one (1) year following the Effective Date of the
            Employment Agreement, I shall not transfer, undertake to transfer,
            otherwise dispose of, pledge, charge or otherwise encumber
            (hereinafter a "DISPOSITION") 180,000 of my Shares (as adjusted to
            an Adjustment Event); and

      (b)   After the period set forth in sub-section (a) above and until the
            lapse of two (2) years following the Effective Date of the
            Employment Agreement, I shall not cause a Disposition of 120,000 of
            my Shares (as adjusted to an Adjustment Event); and

      (c)   After the period set forth in sub-section (b) above and until the
            lapse of three (3) years following the Effective Date of the
            Employment Agreement, I shall not cause a Disposition of 60,000 of
            my Shares (as adjusted to an Adjustment Event).

      (d)   I hereby further acknowledge and expressly agree that the share
            certificate(s) corresponding to the Shares (including any share
            certificate to be issued instead of or in addition to such shares as
            detailed in Section 3 above) may bear a legend indicating that such
            shares are subject to the restrictions provided for hereunder (the
            "RESTRICTIVE LEGEND"). Following the actual release to my possession
            of the Deeds of Transfer or any one of them, as applicable, upon
            delivery to the Company of my written request, I shall be entitled
            to have the Restrictive Legend removed from the share certificate
            issued to me by the Company, with respect to those Shares no longer
            subject to the repurchase right herein. In order to accomplish this
            I shall surrender my share certificate to the Company for its
            replacement with a new share certificate(s), not bearing the
            Restrictive Legend. Notwithstanding the foregoing, the new share
            certificate(s) will continue to bear the following legend:

            "The Shares represented by this certificate, have not been
            registered under the Securities Act of 1933 or under the securities
            laws of any state. These shares have been acquired for investment
            and not with a view to distribution or resale, and may not be sold,
            transferred, pledged or hypothecated in the absence of an effective
            registration statement for such shares under the Securities Act of
            1933 and such state securities laws as maybe applicable or the
            delivery to BIO-IT (BIO INFORMATION TECHNOLOGIES) LTD. of an opinion
            of counsel, reasonably acceptable to it,

<PAGE>

                                       8

            to the effect that registration is not required under such Act or
            such state securities laws.

            The foregoing restrictions terminate when the shares may be freely
            transferred without restriction under Rule 144, under the Securities
            Act of 1933, or any successor thereto, and may be disregarded
            thereafter.

            The sale or transfer of the securities represented by this
            certificate is subject to the terms and conditions of a certain
            Shareholders Agreement dated __________________ and certain
            schedules thereto, by and among the holder hereof and other
            shareholders of the Company. Copies of such agreement and schedules
            may be obtained upon written request to the Company's Secretary."

6.    I hereby represent and warrant to the Repurchaser that the portion of the
      Shares subject to repurchase in accordance with this Undertaking, when
      transferred to the Repurchaser shall be free of any lien, encumbrance
      and/or any right or obligation which may limit the right of the
      Repurchaser in such Shares.

7.    Notwithstanding the above, I reserve the right to transfer any portion of
      my Shares to a Permitted Transferee (as such term is defined in the
      Company's Articles of Association, as same may be amended from time to
      time), provided that any such transferee shall undertake, in writing, to
      fully comply with the provisions of this Undertaking, and shall, upon such
      transfer to such transferee and as a condition precedent to its validity,
      execute appropriate Deed(s) of Transfer, mutatis mutandis.

8.    I hereby agree that I shall have no rights of a shareholder or otherwise
      have any rights with respect to those Shares that have been repurchased,
      or if the Repurchaser is the Company, then with respect to the Shares that
      have reverted back to the Company, all in accordance with the provisions
      set forth above. Subject to the restrictions appearing in this
      undertaking, the Company's Articles of Association, or any other agreement
      to which I am a party, I reserve all rights of a shareholder of the
      Company with respect to those Shares that have not been repurchased or
      have not reverted back to the Company, as applicable.

9.    Notwithstanding anything to the contrary herein, upon the occurrence of
      any one of the following events prior to the end of the Term of Service
      and provided that until the occurrence of any such event I am an employee
      of the Company, the Shares shall no longer be subject to the
      repurchase/reversion provisions set forth above and the Repurchaser or the
      Company, as applicable, shall thereafter have no right to have such Shares
      revert back or transferred to it:

      9.1   upon the consumption of a merger of the Company into another entity
            where the Company is not the surviving entity of the merger
            transaction;

      9.2   upon the consummation of an acquisition of all or substantially all
            of the Company's assets;

<PAGE>

                                       9

      9.3   upon the consummation of an acquisition of all or substantially all
            of the Company's securities, except where the acquirer is at the
            time of such acquisition a 25% or more shareholder in the Company;

      9.4   upon my disability as such term is defined in the Employment
            Agreement;

      9.5   upon the consummation of the Company's initial public offering of
            its securities to the public; and

[ADDRESS]

      RE:   Extension of Employment Agreement dated as of October 31, 2000, as
            amended in early 2001, August 29, 2001, May 12, 2003 and August 11,
            2003, between Oren Becker, PhD and Predix Pharmaceuticals Ltd.
            (collectively, the "Employment Agreement")

Dear Dr. Becker:

      As you may be aware, the Initial Term of the Employment Agreement has
expired and we would like to memorialize our understanding as to your continued
employment with us. Therefore, it is our desire to extend the term of the
Employment Agreement until December 31, 2005 and for one or more additional
one-year periods until otherwise terminated by either party in accordance with
Section 3 of the Employment Agreement, including by either party without cause
on three (3) months prior written notice to the other party.

      To the extent that there are any conflicts between the terms of this
letter and the Employment Agreement, this letter will be deemed to have
superseded those of the Employment Agreement and shall govern the matter in
question.

      I would appreciate it if you would provide me with your approval of the
extension of the Employment Agreement as set forth above by signing and dating
this letter as indicated below at the earliest opportunity.

                                                   Best regards,

                                                   /s/ MICHAEL G. KAUFFMAN

                                                   Michael G. Kaufman

The undersigned hereby acknowledges and agrees to the terms and conditions
above.

/s/ OREN BECKER                                     June 9, 2005
