               delivery and performance of this Agreement by the Company and the
               consummation of the transactions contemplated hereby.

                      (h) (i) There are no contracts, agreements or
               understandings between the Company and any person granting such
               person the right (other than rights which have been waived or
               satisfied) to require the Company to file a registration
               statement under the Securities Act with respect to any securities

               pursuant to Rule 144A under, or Regulations D or S of, the
               Securities Act.

                      (j) Neither the Company nor any of its subsidiaries has
               sustained, since the date of the latest audited financial
               statements included in the Prospectus,



                                      -4-

               any material loss or interference with its business from fire,
               explosion, flood or other calamity, whether or not covered by
               insurance, or from any labor dispute or court or governmental
               action, injunction, order or decree, otherwise than as set forth
               or contemplated in the Prospectus; and, since such date, there
               has not been any change in the share capital or long-term debt of
               the Company or any of its subsidiaries or any material adverse
               change, or any development that could reasonably be expected to
               result in a material adverse change, in or affecting the general
               affairs, management, financial position, shareholders' equity or
               results of operations of the Company and its subsidiaries,
               otherwise than as set forth or contemplated in the Prospectus.

                      (k) The financial statements (including the related notes
               and supporting schedules) filed as part of the Registration
               Statements or included in the Prospectus present fairly the
               financial condition and results of operations of the entities
               purported to be shown thereby, at the dates and for the periods
               indicated, and have been prepared in conformity with generally
               accepted accounting principles in the U.S. ("U.S. GAAP") applied
               on a consistent basis throughout the periods involved. The
               summary consolidated financial data and selected consolidated
               financial data included in the Prospectus present fairly the
               financial information shown therein and have been compiled on a
               basis consistent with the audited financial statements of the
               Company. The pro forma consolidated financial information
               included in the Prospectus (i) is presented fairly in all
               material respects, (ii) has been prepared in accordance with the
               Rules and Regulations with respect to pro forma financial
               statements and (iii) has been properly compiled on the bases
               described therein, and the assumptions used in the preparation of
               the pro forma consolidated financial information included in the
               Prospectus are reasonable and the adjustments used therein are
               appropriate to give effect to the transactions or circumstances
               referred to therein.

                      (l) Luboshitz Kasierer, Member Firm of Arthur Andersen,
               who have certified certain financial statements of the Company,
               whose report appears in the Prospectus and who have delivered the

               independent public accountants as required by the Securities Act
               and the Rules and Regulations and are duly appointed statutory
               auditors of the Company pursuant to Israeli law and regulations.

                      (m) The Company and each of its subsidiaries have good and
               marketable title to all personal property owned by them, in each
               case free and clear of all liens, encumbrances and defects except
               such as are described in the Prospectus or such as do not
               materially affect the value of such property and do not
               materially interfere with the use made and proposed to be made of
               such property by the Company and its subsidiaries; and all real
               property and buildings held under lease by the Company and its
               subsidiaries are held by them under valid, subsisting and
               enforceable leases, with such exceptions as are not material and
               do not interfere with the use made and proposed to be made of
               such property and buildings by the Company and its subsidiaries.
               Neither the Company nor any of its subsidiaries owns any real
               property.

               covered by, insurance in such amounts and covering such risks as

               companies engaged in similar businesses in similar industries.

                      (o) To the Company's knowledge, except as described in the

               know-how (including trade secrets and other unpatented and

               knowledge, neither the Company nor any subsidiary has infringed,
               or received notice of conflict with, any Intellectual Property of

               kind relating to the Intellectual Property of the Company or any
               subsidiary that are required to be described in the Prospectus
               and are not described in all material respects. Neither the

               permits (collectively, "Permits"), of the jurisdictions in which
               it is conducting business, except where failure to be so in

               financial position, shareholders' equity, results of operations,
               business or prospects of the Company and its subsidiaries. For
               purposes of this paragraph, "Permits" shall include Permits

               constitute, the stabilization or manipulation of the price of the
               Ordinary Shares to facilitate the sale or resale of the Shares.

               Exchange Act.

                      (r) There are no legal or governmental proceedings pending
               to which the Company or any of its subsidiaries is a party or of
               which any property or asset of the Company or any of its
               subsidiaries is the subject which are reasonably likely to have a
               material adverse effect on the consolidated financial position,
               shareholders' equity, results of operations, business or
               prospects of the Company and its subsidiaries; and to the
               Company's knowledge, no such proceedings are threatened or
               contemplated by governmental authorities or threatened by others.

                      (s) There are no contracts or other documents which are
               required to be described in the Prospectus or filed as exhibits
               to either of the Registration Statements by the Securities Act or
               by the Rules and Regulations which have not been described in the
               Prospectus or filed as exhibits to either of the Registration
               Statements or incorporated therein by reference as permitted by
               the Rules and Regulations.

                      (t) No relationship, direct or indirect, exists between or
               among the Company on the one hand, and the directors, officers,

                      (u) No labor disturbance by the employees of the Company
               exists or, to the knowledge of the Company, is imminent which
               might be expected to have a material adverse effect on the
               consolidated financial position, shareholders' equity, results of
               operations, business or prospects of the Company and its
               subsidiaries.

                      (v) The Company is in compliance in all material respects
               with all presently applicable provisions of the Employee

               regulations and published interpretations thereunder ("ERISA");
               no "reportable event" (as defined in ERISA) has occurred with
               respect to any "pension plan" (as defined in ERISA) for which the
               Company would have any liability; the Company has not incurred
               and does not expect to incur liability under (i) Title IV of
               ERISA with respect to termination of, or withdrawal from, any

               interpretations thereunder (the "Code"); and each "pension plan"
               for which the Company would have any liability that is intended
               to be qualified under Section 401(a) of the Code is so qualified
               in all material respects and nothing has occurred, whether by
               action or by failure to act, which would cause the loss of such
               qualification.

                      (w) Other than pursuant to applicable law, there are no
               agreements or arrangements (whether legally enforceable or not)
               for the payment of any pensions, allowances, lump sums or other
               like benefits on retirement or on death or termination or during
               periods of sickness or disablement for the benefit of any officer
               or former officer or employee or former employee of the Company
               or for the benefit of the dependents of any such person in
               operation at the date hereof. The Company has fulfilled all its
               obligations under the law to its employees, including with
               respect to payment of overtime work, under the Hours of Work and
               Rest Law. Other than pursuant to orders extending certain
               provisions of collective bargaining agreements between the
               Histadrut (General Federation of Labor in Israel) and the
               Coordinating Bureau of Economic Organization (the federation of
               employers' organizations) or otherwise as required by applicable
               law, the Company is not bound by or subject to (and none of its
               assets or properties is bound by or subject to) any written,
               oral, express or implied, contract, commitment or arrangement
               with any labor union, and no labor union has requested or, to the
               best of the Company's knowledge, has sought to represent any of
               the employees of the Company. There is no strike or other labor
               dispute involving the Company pending, or to the best knowledge
               of the Company threatened.

                      (x) Each of the Company and its subsidiaries has filed
               with the U.S., English and Israeli tax authorities all income and

               be filed through the date hereof and has paid all taxes due
               thereon, and no tax deficiency has been determined adversely to
               the Company or any of its subsidiaries which has had (nor does
               the Company have any knowledge of any tax deficiency which, if
               determined adversely to the Company or any of its subsidiaries,
               might have) a material adverse effect on the consolidated
               financial position, shareholders' equity, results of operations,
               business or prospects of the Company and its subsidiaries.

                      (y) All dividends and other distributions properly
               declared and payable on the Shares may under the current laws and
               regulations of Israel be paid in Israeli currency that may be
               freely converted into U.S. dollars and that may be freely
               transferred from or out of Israel without the necessity of
               obtaining any consents, approvals, authorizations, orders or
               clearances from or registering with any governmental agency or
               body or court of Israel.

                      (z) No stamp or other issuance or transfer taxes or duties
               and no capital gains, income, withholding or other taxes are
               payable by or on behalf of the Underwriters to the government of
               Israel or any political subdivision or taxing authority thereof
               or therein in connection with (i) the issuance and sale of the

               records and (ii) maintains internal accounting controls which
               provide reasonable assurance that (A) transactions are executed

               intervals.

                      (cc) Neither the Company nor any of its subsidiaries, nor
               any director, officer, agent, employee or other person associated
               with or acting on behalf of the Company or any of its
               subsidiaries, has used any corporate funds for any unlawful
               contribution, gift, entertainment or other unlawful expense
               relating to political activity; made any direct or indirect

               remediation of any disposal or release of hazardous or toxic
               substance or wastes, pollutants or contaminants, except where
               such violation or liability could not reasonably be expected to
               have a material adverse effect on the consolidated financial
               position, shareholders' equity, results of operations, business
               or prospects of the Company and its subsidiaries.

                      (ff) The Company has reviewed its operations and that of
               its subsidiaries to evaluate the extent to which the business or
               operations or products of the Company or its subsidiaries will be
               affected by the Year 2000 Problem. As a result of such review,
               the Company has no reason to believe, and does not believe, that
               the Year 2000 problem will have a material adverse effect on the
               financial position, shareholders' equity or results of operations
               of the Company and its subsidiaries or result in any material
               loss or interference with the Company's business or operations.
               The "Year 2000 Problem" as used herein means any significant risk
               that computer hardware or software used in the receipt,
               transmission, processing, manipulation, storage, retrieval,
               retransmission or other utilization of data or in the operation
               of mechanical or electrical systems of any kind will not, in the
               case of dates or time periods occurring after December 31, 1999,
               function at least as effectively as in the case of dates or time
               periods occurring prior to January 1, 2000.

                      (gg) Neither the Company nor any of its subsidiaries is,

               and the rules and regulations of the Commission thereunder.

                      (hh) There are no material acquisitions of businesses or

               investment company ("PFIC") as defined in Section 1296(a) of the
               Code for its fiscal year ended December 31, 1999; and, based upon
               current operating plans and financial projections and the nature
               of the Company's business, the Company does not expect to be
               classified as a PFIC for its current taxable year or for future
               taxable years.

                      (jj) None of the Company, any subsidiary of the Company or

               or of any subsidiary of the Company is (i) a director, officer,
               or partner of any brokerage firm, broker or dealer that is a

               or indirectly, a "person associated with" a NASD member or an
               "affiliate" of a NASD member, as such terms are used in the NASD
               by-laws or rules.

               business) or guarantees of indebtedness by the Company or any of
               its subsidiaries to or for the benefit of any of the officers or
               directors of the Company or any of the members of any of them,

               distribute prior to the later of (i) the Delivery Date, or any
               date on which Option Shares are to be purchased, as the case may
               be, and (ii) completion of the distribution of the Shares, any

               by the Act.

                      (nn) The distribution of each Preliminary Prospectus did
               not violate, and the distribution of the Prospectus and any
               further amendments or supplements to the Prospectus will not
               violate, in any material respect, any applicable law or
               regulation of non-U.S. jurisdictions in which such documents are
               distributed in connection with the Directed Share Program; and no
               consent, approval, authorization or order of, or filing or
               registration with, any governmental agency or body or court is

               non-U.S. jurisdictions in which the Directed Shares are offered
               outside the United States.

                      (oo) Under the laws of Israel, the submission by the
               Company to the jurisdiction of any U.S. Federal or state court
               sitting in the State of New York and the designation of the law
               of the State of New York to apply to this Agreement will be
               binding upon the Company and, if properly brought to the
               attention of the court or administrative body in accordance with
               the laws of Israel, would be enforceable in any judicial or
               administrative proceeding in Israel (subject to any applicable
               exceptions to the recognition or enforcement of foreign judgments
               in Israel).

                      (rr) Each of the Company's 2000 Share Option Plan, 2000
               U.S. Option Plan, 2000 Israeli Plan, 2000 U.K. Unapproved Share
               Option Scheme and 2000 U.K. Approved Share Option Scheme provide
               that vesting of options issued thereunder does not begin for a
               minimum of 1 year from the date of grant of such options (the
               "Option Plans").

                      (ss) The Company has duly and validly appointed CT
               Corporation as its agent for service of process in New York.

               2. Purchase of the Shares by the Underwriters. On the basis of
the representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to sell 5,000,000 shares of
the Firm Shares to the several Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase the number of shares of the Firm
Shares set opposite that Underwriter's name in Schedule 1 hereto. The respective
purchase obligations of the Underwriters with respect to the Firm Shares shall
be rounded among the Underwriters to avoid fractional shares, as the
Representatives may determine.

               In addition, the Company grants to the Underwriters an option to
purchase up to 750,000 shares of Option Shares. Such option is granted solely
for the purpose of covering over-allotments in the sale of Firm Shares and is
exercisable as provided in Section 4 hereof. Shares of Option Shares shall be
purchased severally for the account of the Underwriters in proportion to the
number of shares of Firm Shares set opposite the name of such Underwriters in
Schedule 1 hereto. The respective purchase obligations of each Underwriter with
respect to the Option Shares shall be adjusted by the Representatives so that no
Underwriter shall be obligated to purchase Option Shares other than in 100 share
amounts.

               The price of both the Firm Shares and any Option Shares shall be
$_____ per share.

               The Company shall not be obligated to deliver any of the Shares
to be delivered on the First Delivery Date or the Second Delivery Date (as
hereinafter defined), as the case may be, except upon payment for all the Shares
to be purchased on such Delivery Date as provided herein.

               3. Offering of Shares by the Underwriters. Upon authorization by
the Representatives of the release of the Firm Shares, the several Underwriters
propose to offer the Firm Shares for sale upon the terms and conditions set
forth in the Prospectus; provided, however, that no Shares registered pursuant
to the Rule 462(b) Registration Statement, if any, shall be offered prior to the
Effective Time thereof.

               4. Delivery of and Payment for the Shares. Delivery of and
payment for the Firm Shares shall be made in New York, New York with a
concurrent closing at the offices of Wilson Sonsini Goodrich & Rosati,
professional corporation, 650 Page Mill Road, Palo Alto, California at 10:00
A.M., New York time, on ________, 2000, the fourth full business day following
the date of this Agreement, or at such other date or place as shall be
determined by agreement between the Representatives and the Company. This date
and time are sometimes referred to as the "First Delivery Date." On the First
Delivery Date, the Company shall deliver or cause to be



                                      -12-

delivered certificates representing the Firm Shares to the Representatives for
the account of each Underwriter against payment to or upon the order of the
Company of the purchase price by wire transfer of immediately available funds to
a bank account designated by the Company. Time shall be of the essence, and
delivery at the time and place specified pursuant to this Agreement is a further
condition of the obligation of each Underwriter hereunder. Upon delivery, the
Firm Shares shall be registered in such names and in such denominations as the
Representatives shall request in writing not less than two full business days
prior to the First Delivery Date. For the purpose of expediting the checking and
packaging of the certificates for the Firm Shares, the Company shall make the
certificates representing the Firm Shares available for inspection by the
Representatives in New York, New York, not later than 2:00 P.M., New York time,
on the business day prior to the First Delivery Date.

               At any time on or before the thirtieth day after the date of this
Agreement the option granted in Section 2 may be exercised by written notice
being given to the Company by the Representatives. Such notice shall set forth
the aggregate number of shares of Option Shares as to which the option is being
exercised, the names in which the shares of Option Shares are to be registered,
the denominations in which the shares of Option Shares are to be issued and the
date and time, as determined by the Representatives, when the shares of Option
Shares are to be delivered; provided, however, that this date and time shall not
be earlier than the First Delivery Date nor earlier than the second business day
after the date on which the option shall have been exercised nor later than the
fifth business day after the date on which the option shall have been exercised.
The date and time the shares of Option Shares are delivered are sometimes
referred to as the "Second Delivery Date" and the First Delivery Date and the
Second Delivery Date are sometimes each referred to as a "Delivery Date").

               Delivery of and payment for the Option Shares shall be made at
the place specified in the first sentence of the first paragraph of this Section
4 (or at such other place as shall be determined by agreement between the
Representatives and the Company) at 10:00 A.M., New York time, on the Second
Delivery Date. On the Second Delivery Date, the Company shall deliver or cause
to be delivered the certificates representing the Option Shares to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by wire transfer of immediately
available funds to a bank account designated by the Company. Time shall be of
the essence, and delivery at the time and place specified pursuant to this
Agreement is a further condition of the obligation of each Underwriter
hereunder. Upon delivery, the Option Shares shall be registered in such names
and in such denominations as the Representatives shall request in the aforesaid
written notice. For the purpose of expediting the checking and packaging of the
certificates for the Option Shares, the Company shall make the certificates
representing the Option Shares available for inspection by the Representatives
in New York, New York, not later than 2:00 P.M., New York time, on the business
day prior to the Second Delivery Date.

                      "Enforceability of Civil Liabilities" in the Prospectus,
                      Israeli courts are empowered to enforce foreign final
                      executory judgements, including those of the United
                      States, for liquidated amounts in civil matters. The
                      Company has irrevocably appointed CT Corporation, as the
                      Company's agent to receive service of process in any
                      action against the Company in any federal or state court
                      sitting in New York County, State of New York arising out
                      of the Offerings made pursuant to this Agreement or any
                      purchase or sale of securities in connection therewith.
                      Foreign judgements enforced by Israeli courts generally
                      will be payable in Israeli currency and will be freely
                      convertible into dollars or other foreign currency and may
                      be transferred out of Israel.

               In rendering such opinion, such counsel may (i) state that its
        opinion is limited to matters governed by the laws of the State of
        Israel and (ii) rely (to the extent such counsel deems proper and
        specifies in its opinion), as to matters involving the application of
        the laws of other states or countries upon the opinion of other counsel
        of good standing, provided that such other counsel is satisfactory to
        counsel for the Underwriters and furnishes a copy of its opinion to the
        Representatives. Such counsel shall also have furnished to the
        Representatives a written statement, addressed to the Underwriters and
        dated such Delivery Date, in form and substance satisfactory to the
        Representatives, to the effect that (x) such counsel has acted as
        counsel to the Company on a regular basis since September 1999, has
        acted as counsel to the Company in connection with its financing
        transactions in December 1999 and has acted as counsel to the Company in
        connection with the preparation of the Registration Statements, and (x)
        such counsel has participated in conferences with representatives of the
        Underwriters, officers of the Company and representatives of the
        independent certified public accountants of the Company, at which
        conferences the contents of the Registration Statement and the
        Prospectus and related matters were discussed and (y) based on the
        foregoing, no facts have come to the attention of such counsel which
        lead it to believe that the Registration Statements, as of their
        respective Effective Dates, contained any untrue statement of a material
        fact or omitted to state any material fact required to be stated therein
        or necessary in order to make the statements therein not misleading, or
        that the Prospectus contains any untrue statement of a material fact or
        omits to state any material fact required to be stated therein or
        necessary in order to make the statements therein, in light of the
        circumstances under which they were made, not misleading. The foregoing
        opinion and statement may be qualified by a statement to the effect that
        such counsel does not assume any responsibility for the accuracy,
        completeness or fairness of the statements contained in the Registration
        Statements or the Prospectus, including the financial statements,
        supporting schedules or other financial and statistical data, except as
        provided in paragraphs (ii) and (xiii) above.

               to the Representatives its written opinion, as counsel to the
               Company, addressed to the Underwriters and dated such Delivery
               Date, in form and substance reasonably satisfactory to the

                      valid, subsisting and enforceable leases, with such
                      exceptions as are not material and do not interfere with
                      the use made and proposed to be made of such property and

                      any property or asset of the Company or any of its
                      subsidiaries is the subject which, if determined adversely
                      to the Company or any of its subsidiaries, might have a
                      material adverse effect on the consolidated financial

               deems proper and specifies in its opinion), as to matters
               involving the application of the laws of other states upon the
               opinion of other counsel of good standing, provided that such
               other counsel is satisfactory to counsel for the Underwriters and

               counsel shall also have furnished to the Representatives a
               written statement, addressed to the Underwriters and dated such
               Delivery Date, in form and substance satisfactory to the
               Representatives, to the effect that (x) such counsel has acted as
               counsel to the Company on a regular basis (although the Company
               is also represented by other outside counsel with respect to
               matters relating to Israeli law), has acted as counsel to the
               Company in connection with the preparation of the Registration
               Statements, and (y) based on the foregoing, no facts have come to
               the attention of such counsel which lead it to believe that the

               contained any untrue statement of a material fact or omitted to
               state any material fact required to be stated therein or
               necessary in order to make the statements therein not misleading,
               or that the Prospectus contains any untrue statement of a
               material fact or omits to state any material fact required to be
               stated therein or necessary in order to make the statements
               therein, in light of the circumstances under which they were
               made, not misleading. The foregoing opinion and statement may be
               qualified by a statement to the effect that such counsel does not
               assume any responsibility for the accuracy, completeness or
               fairness of the statements contained in the Registration
               Statements or the

               Prospectus except for the statements made in the Prospectus under
               the captions "United States Federal Income Tax Considerations"
               the caption referred to in paragraphs (viii) and (xiv) above,
               insofar as such statements concern legal matters.

                      (f) Bird & Bird, English counsel to the Company, shall
               have furnished to the Representatives their written opinion,
               addressed to the Underwriters and dated such Delivery Date, in
               form and substance satisfactory to the Representatives, to the
               effect that:

                             (i) ClickService Software (Europe) Ltd., the "UK
                      Subsidiary" was duly incorporated under the laws of
                      England and Wales on 15 March 1995;

                             (ii) The U.K. Subsidiary has the necessary
                      corporate power and authority to own, lease and operate
                      its properties and assets and conduct the businesses in
                      which it is engaged;

                             (iii) the UK Subsidiary is duly organized, validly
                      existing and in good standing in the sense that the
                      Company Microfiche did not reveal any application or order
                      or resolution for the winding-up of the UK Subsidiary and
                      no notice of the appointment of a receiver or manager or
                      administrative receiver or administrator or of an
                      administration order having been made in respect of the UK
                      Subsidiary;

                             (iv) the UK Subsidiary has the requisite corporate
                      power and authority to own, lease and operate its
                      properties and assets and conduct the business in which it
                      is engaged;

                             (v) the issued share capital of the UK Subsidiary
                      comprises 100 ordinary shares of Pound Sterling1.00
                      nominal value each. All such issued shares have been
                      validly issued as fully paid and comprise part of the
                      authorized share capital of the UK Subsidiary;

                             (vi) the Register of Members of the UK Subsidiary
                      discloses that 100 issued shares of the UK Subsidiary are
                      registered in the name of the Company;

                             (vii) there are no pre-emptive or other rights to
                      subscribe for or purchase, nor any restriction upon voting
                      of, any shares of the UK Subsidiary pursuant to its
                      Memorandum and Articles of Association or English law; and

                             (viii) Regulation 57 of Table A of the Companies
                      (Tables A to F) Regulations 1985 (SI 1985 No 805) has been
                      adopted by the UK Subsidiary and provides that no member
                      may vote at any general meeting unless all moneys payable
                      by him in respect of his shares have been paid.



                                      -27-
<PAGE>   28

                      Any shares issued by the UK Subsidiary that are not fully
                      paid will therefore not carry the right to vote.

                      In rendering the foregoing opinion, such counsel may state
               that their opinion is limited to matters governed by the laws of
               the United Kingdom.

                      (g) The Representatives shall have received from Simpson
               Thacher & Bartlett, U.S. counsel for the Underwriters, such
               opinion or opinions, dated such Delivery Date, with respect to
               the issuance and sale of the Shares, the Registration Statement,
               the Prospectus and other related matters as the Representatives
               may reasonably require, and the Company shall have furnished to
               such counsel such documents as they reasonably request for the
               purpose of enabling them to pass upon such matters.

                      (h) The Representatives shall have received from Doron
               Cohen -- David Cohen, Law Offices, Israeli counsel for the
               Underwriters, such opinion or opinions, dated such Delivery Date,
               with respect to the issuance and sale of the Shares, the
               Registration Statement, the Prospectus and other related matters
               as the Representatives may reasonably require, and the Company
               shall have furnished to such counsel such documents as they
               reasonably request for the purpose of enabling them to pass upon
               such matters.

                      (i) At the time of execution of this Agreement, the
               Representatives shall have received from Luboshitz Kasierer,
               Member Firm of Arthur Andersen, a letter, in form and substance
               satisfactory to the Representatives, addressed to the
               Underwriters and dated the date hereof (i) confirming that they
               are independent public accountants within the meaning of the
               Securities Act and are in compliance with the applicable
               requirements relating to the qualification of accountants under
               Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as
               of the date hereof (or, with respect to matters involving changes
               or developments since the respective dates as of which specified
               financial information is given in the Prospectus, as of a date
               not more than five days prior to the date hereof), the
               conclusions and findings of such firm with respect to the
               financial information and other matters ordinarily covered by
               accountants' "comfort letters" to underwriters in connection with
               registered public offerings.

                      (j) With respect to the letter of Luboshitz Kasierer,
               Member Firm of Arthur Andersen, referred to in the preceding
               paragraph and delivered to the Representatives concurrently with
               the execution of this Agreement (as used in this paragraph, the
               "initial letter"), the Company shall have furnished to the
               Representatives a letter (as used in this paragraph, the
               "bring-down letter") of such accountants, addressed to the
               Underwriters and dated such Delivery Date (i) confirming that
               they are independent public accountants within the meaning of the
               Securities Act and are in compliance with the applicable
               requirements relating to the qualification of accountants under
               Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as
               of the date of the bring-down letter (or, with respect to matters
               involving changes or developments since the respective dates as
               of which specified financial information is given in the
               Prospectus, as of a date not



                                      -28-
<PAGE>   29

               more than five days prior to the date of the bring-down letter),
               the conclusions and findings of such firm with respect to the
               financial information and other matters covered by the initial
               letter and (iii) confirming in all material respects the
               conclusions and findings set forth in the initial letter.

                      (k) The Company shall have furnished to the
               Representatives a certificate, dated such Delivery Date, of its
               Chairman of the Board, its President or a Vice President and its
               chief financial officer stating that:

                             (i) The representations, warranties and agreements
                      of the Company in Section 1 are true and correct as of
                      such Delivery Date; the Company has complied with all its
                      agreements contained herein; and the conditions set forth
                      in Section 7(a) have been fulfilled;

                             (ii) They have carefully examined the Registration
                      Statements and the Prospectus and, in their opinion (A)
                      the Registration Statements, as of their respective
                      Effective Dates, and the Prospectus, as of each of the
                      Effective Dates, did not include any untrue statement of a
                      material fact and did not omit to state any material fact
                      required to be stated therein or necessary to make the
                      statements therein not misleading, and (B) since the
                      Effective Date of the Primary Registration Statement, no
                      event has occurred which should have been set forth in a
                      supplement or amendment to either of the Registration
                      Statements or the Prospectus.

                             (iii) To their knowledge, no stop order suspending
                      the effectiveness of either of the Registration Statements
                      or any part thereof has been issued and no proceeding for
                      that purpose has been initiated or threatened by the
                      Commission.

                      (l) (i) Neither the Company nor any of its subsidiaries
               shall have sustained since the date of the latest audited
               financial statements included in the Prospectus any loss or
               interference with its business from fire, explosion, flood or
               other calamity, whether or not covered by insurance, or from any
               labor dispute or court or governmental action, order or decree,
               otherwise than as set forth or contemplated in the Prospectus or
               (ii) since such date there shall not have been any change in the
               share capital or long-term debt of the Company or any of its
               subsidiaries or any change, or any development involving a
               prospective change, in or affecting the general affairs,
               management, financial position, shareholders' equity or results
               of operations of the Company and its subsidiaries, otherwise than
               as set forth or contemplated in the Prospectus, the effect of
               which, in any such case described in clause (i) or (ii), is, in
               the judgment of the Representatives, so material and adverse as
               to make it impracticable or inadvisable to proceed with the
               public offering or the delivery of the Shares being delivered on
               such Delivery Date on the terms and in the manner contemplated in
               the Prospectus.

                      (m) Subsequent to the execution and delivery of this
               Agreement there shall not have occurred any of the following: (i)
               trading in securities generally on the New York Stock Exchange or
               the American Stock Exchange or in the over-the-counter market, or
               trading in any securities of the Company on any exchange



                                      -29-
<PAGE>   30

               or in the over-the-counter market, shall have been suspended or
               minimum prices shall have been established on any such exchange
               or such market by the Commission, by such exchange or by any
               other regulatory body or governmental authority having
               jurisdiction, (ii) a banking moratorium shall have been declared
               by Federal or state authorities, (iii) the United States shall
               have become engaged in hostilities, there shall have been an
               escalation in hostilities involving the United States or there
               shall have been a declaration of a national emergency or war by
               the United States or (iv) there shall have occurred such a
               material adverse change in general economic, political or
               financial conditions (or the effect of international conditions
               on the financial markets in the United States shall be such) as
               to make it, in the judgment of a majority in interest of the
               several Underwriters, impracticable or inadvisable to proceed
               with the public offering or delivery of the Shares being
               delivered on such Delivery Date on the terms and in the manner
               contemplated in the Prospectus.

                       (n) The NASDAQ National Market System shall have approved
               the Shares for inclusion, subject only to official notice of
               issuance and evidence of satisfactory distribution.

               All opinions, letters, evidence and certificates mentioned above
or elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

               8.     Indemnification and Contribution.

               (a) The Company shall indemnify and hold harmless each
Underwriter, its officers and employees and each person, if any, who controls
any Underwriter within the meaning of the Securities Act, from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof (including, but not limited to, any loss, claim, damage, liability or
action relating to purchases and sales of Shares), to which that Underwriter,
officer, employee or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any Preliminary Prospectus, either
of the Registration Statements or the Prospectus, or in any amendment or
supplement thereto or (B) in any materials or information provided to investors
by, or with the approval of, the Company in connection with the marketing of the
offering of the Shares, including any marketing or investor presentation made to
investors by the Company (whether in person or electronically ) ("Marketing
Materials"), (ii the omission or alleged omission to state in any Preliminary
Prospectus, either of the Registration Statements or the Prospectus, or in any
amendment or supplement thereto, or in any Marketing Materials any material fact
required to be stated therein or necessary to make the statements therein not
misleading or (iii) any act or failure to act, or any alleged act or failure to
act, by any Underwriter in connection with, or relating in any manner to, the
Shares or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising out of or
based upon matters covered by clause (i) or (ii) above (provided that the
Company shall not be liable in the case of any matter covered by this clause
(iii) to the extent that it is determined in a final judgement by a court of
competent jurisdiction that such loss, claim, damage, liability or action
resulted directly from any such act or failure to act undertaken or omitted to
be taken by such Underwriter through



                                      -30-
<PAGE>   31

its gross negligence or wilful misconduct), and shall reimburse each Underwriter
and each such officer, employee and controlling person promptly upon demand for
any legal or other expenses reasonably incurred by that Underwriter, officer,
employee or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of, or is based upon, any untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statements or the Prospectus, or in any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company through the Representatives by or on behalf
of any Underwriter specifically for inclusion therein and described in Section
8(e); and provided further that as to any Preliminary Prospectus this indemnity
agreement shall not inure to the benefit of any Underwriter, its officers or
employees or any person controlling that Underwriter on account of any loss,
claim, damage, liability or action arising from the sale of Shares to any person
by that Underwriter if that Underwriter failed to send or give a copy of the
Prospectus, as the same may be amended or supplemented, to that person within
the time required by the Securities Act, and the untrue statement or alleged
untrue statement of any material fact or omission or alleged omission to state a
material fact in such Preliminary Prospectus was corrected in the Prospectus,
unless such failure resulted from non-compliance by the Company with Section
5(c). The foregoing indemnity agreement is in addition to any liability which
the Company may otherwise have to any Underwriter or to any officer, employee or
controlling person of that Underwriter.

               (b) Each Underwriter, severally and not jointly, shall indemnify
and hold harmless the Company, its officers and employees, each of its directors
and each person, if any, who controls the Company who within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, either of
the Registration Statements or the Prospectus, or in any amendment or supplement
thereto or (ii) the omission or alleged omission to state in any Preliminary
Prospectus, either of the Registration Statements or the Prospectus, or in any
amendment or supplement thereto, any material fact required to be stated therein
or necessary to make the statements therein not misleading, but in each case
only to the extent that the untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company through the Representatives by or
on behalf of that Underwriter specifically for inclusion therein and described
in Section 8(e), and shall reimburse the Company and any such director, officer
or controlling person for any legal or other expenses reasonably incurred by the
Company or any such director, officer or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability which any Underwriter may
otherwise have to the Company or any such director, officer or controlling
person.

               (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in



                                      -31-
<PAGE>   32

respect thereof is to be made against the indemnifying party under this Section
8, notify the indemnifying party in writing of the claim or the commencement of
that action; provided, however, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have under this
Section 8 except to the extent it has been materially prejudiced by such failure
and, provided further, that the failure to notify the indemnifying party shall
not relieve it from any liability which it may have to an indemnified party
otherwise than under this Section 8. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying party
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party. After notice from the indemnifying party
to the indemnified party of its election to assume the defense of such claim or
action, the indemnifying party shall not be liable to the indemnified party
under this Section 8 for any legal or other expenses subsequently incurred by
the indemnified party in connection with the defense thereof other than
reasonable costs of investigation; provided, however, that the Representatives
shall have the right to employ counsel to represent jointly the Representatives
and those other Underwriters and their respective officers, employees and
controlling persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the Underwriters against the Company
under this Section 8 if, in the reasonable judgment of the Representatives, it
is advisable for the Representatives and those Underwriters, officers, employees
and controlling persons to be jointly represented by separate counsel, and in
that event the fees and expenses of such separate counsel shall be paid by the
Company, any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless (i) the employment thereof has been specifically authorized by the
indemnifying party in writing, (ii) such indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ separate counsel or (iii) the
indemnifying party has failed to assume the defense of such action and employ
counsel reasonably satisfactory to the indemnified party, in which case, if such
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of such indemnified party, it being understood, however, that the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for all such indemnified parties, which firm shall be designated in writing
by the Representatives, if the indemnified parties under this Section 8 consist
of any Underwriter or any of their respective officers, employees or controlling
persons, or by the Company, if the indemnified parties under this Section
consist of the Company or any of the Company's directors, officers, employees or
controlling persons. No indemnifying party shall (i) without the prior written
consent of the indemnified parties (which consent shall not be unreasonably
withheld), settle or compromise or consent to the entry of any judgment with
respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified parties are actual or potential parties to such
claim or action) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action, suit or proceeding, or (ii) be liable for any settlement
of any such action

effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment of the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss of
liability by reason of such settlement or judgment.

               (d) If the indemnification provided for in this Section 8 shall
for any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company on the one hand and the Underwriters on the other from
the offering of the Shares or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters on
the other with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other with respect to such
offering shall be deemed to be in the same proportion as the total net proceeds
from the offering of the Shares purchased under this Agreement (before deducting
expenses) received by the Company, on the one hand, and the total underwriting
discounts and commissions received by the Underwriters with respect to the
Shares purchased under this Agreement, on the other hand, bear to the total
gross proceeds from the offering of the Shares under this Agreement, in each
case as set forth in the table on the cover page of the Prospectus. The relative
fault shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company or the Underwriters, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Underwriters agree that it would not be just and equitable if contributions
pursuant to this Section 8(d) were to be determined by pro rata allocation (even
if the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section 8(d) shall be deemed to include, for
purposes of this Section 8(d), any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 8(d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public was offered to the public exceeds the amount of any damages which
such Underwriter has otherwise paid or become liable to pay by reason of any
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Underwriters' obligations
to contribute as provided in this Section 8(d) are several in proportion to
their respective underwriting obligations and not joint.

               (e) The Underwriters severally confirm that the statements with
respect to the public offering of the Shares set forth on the cover page of, and
under the caption "Underwriting"



                                      -33-
<PAGE>   34

in, the Prospectus are correct and constitute the only information furnished in
writing to the Company by or on behalf of the Underwriters specifically for
inclusion in the Registration Statements and the Prospectus.

               9. Directed Share Program. It is understood that approximately
300,000 shares of the Firm Shares ("Directed Shares") will initially be reserved
by the Underwriters for offer and sale to officers, directors, employees and
consultants of the Company and their family members and to other persons having
business relationships with the Company and its subsidiaries ("Directed Share
Participants") upon the terms and conditions set forth in the Prospectus and in
accordance with the rules and regulations of the National Association of
Securities Dealers, Inc. Under no circumstances will Lehman Brothers Inc. or any
Underwriter be liable to the Company or to any Directed Share Participant for
any action taken or omitted to be taken in good faith in connection with such
Directed Share Program. To the extent that any Directed Shares are not
affirmatively confirmed for purchase by any Directed Share Participant on or
immediately after the date of this Agreement, such Directed Shares may be
offered to the public upon the terms and conditions set forth in the Prospectus.

               The Company agrees to pay all fees and disbursements incurred by
the Underwriters in connection with the Directed Share Program, including
counsel fees and any stamp duties or other taxes incurred by the Underwriters in
connection with the Directed Share Program.

               In connection with the offer and sale of the Directed Shares, the
Company agrees, promptly upon a request in writing, to indemnify and hold
harmless Lehman Brothers Inc. and the other Underwriters from and against any
loss, claim, damage, expense, liability or action which (i) arises out of, or is
based upon, any untrue statement or alleged untrue statement of a material fact
contained in any material prepared by or with the approval of the Company for
distribution to Directed Share Participants in connection with the Directed
Share Program or any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) arises out of the failure of any Directed Share Program
participant to pay for and accept delivery of Directed Shares that the
Participant agreed to purchase or (iii) is otherwise related to the Directed
Share Program, other than losses, claims, damages or liabilities (or expenses
relating thereto) that are finally judicially determined to have resulted
directly from the bad faith or gross negligence of Lehman Brothers Inc.

               10. Defaulting Underwriters. If, on either Delivery Date, any
Underwriter defaults in the performance of its obligations under this Agreement,
the remaining non-defaulting Underwriters shall be obligated to purchase the
Shares which the defaulting Underwriter agreed but failed to purchase on such
Delivery Date in the respective proportions which the number of shares of the
Firm Shares set opposite the name of each remaining non-defaulting Underwriter
in Schedule 1 hereto bears to the total number of shares of the Firm Shares set
opposite the names of all the remaining non-defaulting Underwriters in Schedule
1 hereto; provided, however, that the remaining non-defaulting Underwriters
shall not be obligated to purchase any of the Shares on such Delivery Date if
the total number of Shares which the defaulting Underwriter or Underwriters
agreed but failed to purchase on such date exceeds 9.09% of the total number of
Shares to be purchased on such Delivery Date, and any remaining non-defaulting
Underwriter shall not be obligated to purchase more than 110% of the number of
Shares which it agreed to



                                      -34-
<PAGE>   35

purchase on such Delivery Date pursuant to the terms of Section 2. If the
foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or
those other underwriters satisfactory to the Representatives who so agree, shall
have the right, but shall not be obligated, to purchase, in such proportion as
may be agreed upon among them, all the Shares to be purchased on such Delivery
Date. If the remaining Underwriters or other underwriters satisfactory to the
Representatives do not elect to purchase the shares which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such Delivery Date,
this Agreement (or, with respect to the Second Delivery Date, the obligation of
the Underwriters to purchase, and of the Company to sell, the Option Shares)
shall terminate without liability on the part of any non-defaulting Underwriter
or the Company, except that the Company will continue to be liable for the
payment of expenses to the extent set forth in Sections 6 and 12. As used in
this Agreement, the term "Underwriter" includes, for all purposes of this
Agreement unless the context requires otherwise, any party not listed in
Schedule 1 hereto who, pursuant to this Section 10, purchases Firm Shares which
a defaulting Underwriter agreed but failed to purchase.

               Nothing contained herein shall relieve a defaulting Underwriter
of any liability it may have to the Company for damages caused by its default.
If other underwriters are obligated or agree to purchase the Shares of a
defaulting or withdrawing Underwriter, either the Representatives or the Company
may postpone the First Delivery Date for up to seven full business days in order
to effect any changes that in the opinion of counsel for the Company or counsel
for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

               11. Termination. The obligations of the Underwriters hereunder
may be terminated by the Representatives by notice given to and received by the
Company prior to delivery of and payment for the Firm Shares if, prior to that
time, any of the events described in Sections 7(l) or 7(m) shall have occurred
or if the Underwriters shall decline to purchase the Shares for any reason
permitted under this Agreement.

               12. Reimbursement of Underwriters' Expenses. If (a) the Company
shall fail to tender the Shares for delivery to the Underwriters for any reason
permitted under this Agreement, or (b) the Underwriters shall decline to
purchase the Shares for any reason permitted under this Agreement (including the
termination of this Agreement pursuant to Section 11), the Company shall
reimburse the Underwriters for the reasonable fees and expenses of their counsel
and for such other out-of-pocket expenses as shall have been incurred by them in
connection with this Agreement and the proposed purchase of the Shares, and upon
demand the Company shall pay the full amount thereof to the Representatives. If
this Agreement is terminated pursuant to Section 11 by reason of the default of
one or more Underwriters, the Company shall not be obligated to reimburse any
defaulting Underwriter on account of those expenses.

               13. Notices, etc. All statements, requests, notices and
agreements hereunder shall be in writing, and:

                      (a)  if to the Underwriters, shall be delivered or sent
               by mail, telex or facsimile transmission to:

                             FORM OF LOCK-UP LETTER

LEHMAN BROTHERS INC.

As Representatives of the several
   Underwriters,
c/o Lehman Brothers Inc.
Three World Financial Center
New York New York 10285

Dear Sirs:

        The undersigned understands that you and certain other firms propose to
enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") providing
for the purchase by you and such other firms (the "UNDERWRITERS") of shares (the
"SHARES") of ordinary shares, par value NIS 0.01 nominal value per share (the
"ORDINARY SHARES"), of ClickSoftware Technologies Ltd., an Israeli corporation
(formerly known as IET - Intelligent Electronics Ltd., the "COMPANY"), and that
the Underwriters propose to reoffer the Shares to the public (the "OFFERING").

        In consideration of the execution of the Underwriting Agreement by the
Underwriters, and for other good and valuable consideration, the undersigned
hereby irrevocably agrees that, without the prior written consent of Lehman
Brothers Inc. ("LEHMAN BROTHERS"), on behalf of the Underwriters, the
undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge,
or otherwise dispose of (or enter into any transaction or device that is
designed to, or could be expected to, result in the disposition by any person at
any time in the future of) any shares of Ordinary Shares (including, without
limitation, shares of Ordinary Shares that may be deemed to be beneficially
owned by the undersigned in accordance with the rules and regulations of the
Securities and Exchange Commission and shares of Ordinary Shares that may be
issued upon exercise of any option or warrant) or securities convertible into or
exchangeable for Ordinary Shares or substantially similar securities owned by
the undersigned on the date of execution of this Lock-Up Letter Agreement or on
the date of the completion of the Offering, or sell or grant options, rights or
warrants with respect to any shares of Ordinary Shares or substantially similar
securities (other than the grant of options pursuant to option plans existing on
the date hereof) or (2) enter into any swap or other derivatives transaction
that transfers to another, in whole or in part, any of the economic benefits or
risks of ownership of such shares of Ordinary Shares, whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Ordinary Shares or other securities, in cash or otherwise, for a period of 180
days after the effective date of the Underwriting Agreement relating to the
Offering.

        Notwithstanding the foregoing, if the undersigned is an individual, he
or she may transfer any Ordinary Shares or securities convertible into or
exchangeable or exercisable for Ordinary Shares either during his or her
lifetime or upon death by will or intestacy to his or her immediate family or to
a trust if the beneficiaries of such trust are exclusively the undersigned
and/or a member or members of his or her immediate family; provided, however ,
that prior to any such transfer each transferee shall execute an agreement
substantially identical to this agreement and which shall be satisfactory to
Lehman Brothers, pursuant to which each transferee shall agree to receive and
hold such Ordinary Shares, or securities convertible into or exchangeable or
exercisable for Ordinary Shares, subject to the provisions hereof, and there
shall be no further



                                      -1-
<PAGE>   41

transfer except in accordance with the provisions hereof. In addition, if the
undersigned is a partnership, the partnership may transfer any Ordinary Shares
or securities convertible into or exchangeable or exercisable for Ordinary
Shares to a partner of such partnership, to a retired partner of such
partnership, or to the estate of any such partner or retired partner, and any
such partner who is an individual may transfer such Ordinary Shares or
securities convertible into or exchangeable or exercisable for Ordinary Shares
by gift, will or intestacy to a member or members of his or her immediate
family; provided, however, that prior to any such transfer each transferee shall
execute an agreement substantially identical to this agreement and which shall
be satisfactory to Lehman Brothers, pursuant to which each transferee shall
agree to receive and hold such Ordinary Shares or securities convertible into or
exchangeable or exercisable for Ordinary Shares, subject to the provisions
hereof, and there shall be no further transfer except in accordance with the
provisions hereof. For purposes of this paragraph, "immediate family" shall mean
spouse, lineal descendant, father, mother, brother, sister or domestic partner
of the transferor.

        In furtherance of the foregoing, the Company and its Transfer Agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

        It is understood that, if Lehman Brothers notifies the undersigned that
it does not intend to proceed with the Offering or if the Underwriting Agreement
(other than the provisions thereof which survive termination), after it becomes
effective, shall terminate or be terminated prior to payment for and delivery of
the Shares, the undersigned will be released from its obligations under this
Lock-Up Letter Agreement.

        The undersigned understands that the Company and the Underwriters will
proceed with the Offering in reliance on this Lock-Up Letter Agreement.

        Whether or not the Offering actually occurs depends on a number of
factors, including market conditions. Any Offering will only be made pursuant to
an Underwriting Agreement, the terms of which are subject to negotiation between
the Company and the Underwriters.

        The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Lock-Up Letter Agreement and that,
upon request, the undersigned will execute any additional documents necessary in
connection with the enforcement hereof. Any obligations of the undersigned shall
