                  set forth hereunder shall be binding upon all Shareholders,
                  including such Shareholders who are not a party to this
                  Agreement and that upon execution of this Agreement, its terms
                  shall be binding upon the Company and each and all of the
                  Shareholders, as if such parties would have been parties
                  hereto.

         1.3.     Effect of Agreement

                  By executing this Agreement, the Existing SRA is hereby
                  amended and replaced by this SRA. The provisions of this SRA
                  shall binding upon the shareholders of the Company, provided
                  however, that nothing herein contained shall derogate form the
                  rights and obligations of the shareholders of the Company
                  under the Existing SRA, insofar as same relates to the period
                  prior to the date hereof.

2.       INCIDENTAL REGISTRATION.

         2.1.     If, at any time (i) the Company proposes to register any of
                  its securities (including in the event of the Company's IPO)
                  or (ii) the Company proposes to register any securities owned
                  by anyone other than the Investor Holders, other than (a) in a
                  registration under Section 3 of this Agreement or (b) a
                  registration on Form S-8 or Form F-4, the Company shall give
                  notice to the Holders of such

                                      -8-
<PAGE>   9
                  intention, at least 45 days prior to the filing of the
                  registration statement in connection with such registration.
                  Upon the written request of any Holder given within twenty
                  (20) days after receipt of any such notice, the Company shall
                  include in such registration all of the Registrable Shares
                  indicated in such request(s) of the Investor Holders, so as to
                  permit the disposition of the shares so requested.

         2.2.     Notwithstanding any other provision of this Section 2, if the
                  managing underwriter advises the Company in writing that in
                  its opinion the number of securities requested to be included
                  in such registration exceeds the number that can be sold in
                  such offering without adversely affecting such underwriter's
                  ability to effect an orderly distribution of such securities,
                  the Company will include in such registration: (i) first, the
                  Company's Securities; (ii) second, the number of Investor
                  Registrable Shares requested to be included that, in the
                  opinion of such underwriters, can be sold, pro rata, among the
                  holders of such securities on the basis of the number of
                  Investor Registrable Shares requested to be included by such
                  holders in the registration; and (iii) third, the number of
                  Ordinary Registrable Shares requested to be included that, in
                  the opinion of such underwriters, can be sold, pro rata, among
                  the holders of such securities on the basis of the number of
                  Ordinary Registrable Shares requested to be included by such
                  holders in the registration; provided, however, that in any
                  event, all Investor Registrable Shares must be included in
                  such registration prior to the Ordinary Registrable Shares and
                  any other shares of the Company (with the exception of shares
                  to be issued by the Company to the public).

3.       DEMAND REGISTRATION.

         3.1.     At any time following 120 days after the closing of the
                  Company's IPO, the Initiating Holders may request in writing
                  that all or part of their Investor Registrable Shares shall be
                  registered under the Securities Act. Within 20 days after
                  receipt of any such request, the Company shall give written
                  notice of such request to the other Holders, and shall include
                  in such registration all Registrable Shares held by all such
                  Holders who wish to participate in such demand registration
                  and provide the Company with written requests for inclusion
                  therein within 20 days after the receipt of the Company's
                  notice. Thereafter, the Company shall effect the registration
                  of all Registrable Shares as to which it has received requests
                  for registration (a "DEMAND") and in connection with the first
                  Demand after the Company's IPO (the "FIRST DEMAND"), use its
                  best efforts to have such First Demand effective by the 61st
                  day after the Initiating Holders make such First Demand.
                  Notwithstanding the foregoing, the Company shall have the
                  right, exercisable by the 31st day after such First Demand, to
                  nullify such Demand in order to file a registration statement
                  for the registration of its equity securities for its own
                  account. Subject to the provisions of this Section 3.1, no
                  Demand shall be binding on the Company if the Company has
                  filed any

                                      -9-
<PAGE>   10
                  registration statement for the registration of its equity
                  securities for its own account within the previous one hundred
                  and eighty (180) days (other than a form S-8 or similar
                  registration for employee shares) or, if not for the Company's
                  account, within the previous ninety (90) days.

         3.2.     The Initiating Holders shall have the right to three (3)
                  Demands. Subsequent to the First Demand, no Demand shall be
                  effective unless Initiating Holders holding at least 10% of
                  the unregistered Series D Investor Registrable Shares (other
                  than any such Holders who are holding Preferred A, Preferred B
                  or Preferred C Shares or Investor Registrable Shares issued in
                  respect thereof) join in such Demand.

         3.3.     Any registration proceeding begun pursuant to Sections 3.1 or
                  3.2 that is subsequently withdrawn at the request of the
                  Initiating Holders (with respect to their Demand) shall count
                  toward the quota of registration statements which the Investor
                  Holders have the right to cause to effect pursuant to Section
                  3.2; provided further, however, that such withdrawn
                  registration shall not be so counted if such withdrawal is
                  based upon material adverse information relating to the
                  Company or its condition, business, prospects or general
                  securities market conditions which is different from that
                  generally known to the Initiating Holders at the time of their
                  request. In addition, in the event that the Company utilizes
                  its right under Section 3.1 to file a registration statement
                  for its own account by the 31st day subsequent to the making
                  of the First Demand, such Demand shall not count toward the
                  quota of registration statements which the Investor Holders
                  have the right to cause to effect pursuant to Section 3.2.
                  Only the Initiating Holders who make a Demand under Sections
                  3.1 and 3.2 shall have the right to withdraw registration
                  proceedings under Sections 3.1 and 3.2 (with respect to their
                  Demand).

         3.4.     Founder Demand. At any time at least 90 days following the
                  closing of the second of the Demand registrations to occur
                  under Section 3.1, the Initiating Founders may request in
                  writing that all or part of the Founder Registrable Shares
                  shall be registered under the Securities Act. Within 15 days
                  after receipt of any such request, the Company shall give
                  written notice of such request to the other Holders, and shall
                  include in such registration all Registrable Shares held by
                  all such Holders who wish to participate in such demand
                  registration (subject to the limitation below) and provide the
                  Company with written requests for inclusion therein within 20
                  days after the receipt of the Company's notice. Thereupon, the
                  Company shall effect the registration of all Registrable
                  Shares as to which it has received requests for registration
                  (subject to the limitation below). Notwithstanding the above,
                  the maximum number of Founder Registrable Shares that may be
                  included in a registration under this Section 3.4 shall be
                  three times the number of Founder Registrable Shares that the
                  two Founders would together be entitled under Rule 144 of the
                  Securities Act (as currently enacted) to sell during the three
                  month period beginning on the date of the request for
                  registration by the Initiating Founders, assuming that the

                                      -10-
<PAGE>   11
                  Founders are "affiliates" at the time of the registration and
                  that the initial minimum holding period for restricted
                  securities under Rule 144 has passed.

         3.5.     The Company shall not be required to effect more than one (1)
                  registration under Section 3.4, provided, however, that any
                  registration proceeding begun pursuant to Section 3.4 that is
                  subsequently withdrawn at the request of the Initiating
                  Founders shall count toward the one registration statement
                  pursuant to Section 3.4; provided further, however, that such
                  withdrawn registration shall not be so counted if such
                  withdrawal is based upon material adverse information relating
                  to the Company or its condition, business, or prospects which
                  is different from that generally known to the Initiating
                  Founders at the time of their request. Only the Initiating
                  Founders shall have the right to withdraw a registration
                  proceeding under Section 3.4.

         3.6.     Notwithstanding any other provision of this Section 3, if the
                  managing underwriter advises the Investor Holders in writing
                  that in the managing underwriter's opinion the number of
                  securities requested to be included in such registration
                  exceeds the number that can be sold in such offering without
                  adversely affecting such underwriter's ability to effect an
                  orderly distribution of such securities, the Company will
                  include in such registration:

                           1        first, the number of Investor Registrable
                                    Shares requested to be included that, in the
                                    opinion of such underwriters, can be sold,
                                    provided that if, in the opinion of the
                                    managing underwriter, less than all Investor
                                    Registrable Shares requested to be included
                                    can be included in such Demand registration,
                                    then allocation among the Investor Holders
                                    shall be made pro rata among the Investor
                                    Holders participating in such Demand on the
                                    basis of the number of Investor Registrable
                                    Shares which each Investor Holder seeking to
                                    participate in such Demand has requested be
                                    included in such registration;

                           2        second, the number of Ordinary Registrable
                                    Shares requested to be included that, in the
                                    opinion of such underwriters, can be sold,
                                    pro rata, among the holders of such
                                    securities on the basis of the number of
                                    Ordinary Registrable Shares which each
                                    holder of Ordinary Registrable Shares
                                    seeking to participate in such Demand has
                                    requested to be included in such
                                    registration; provided, however, that in any
                                    event, all Investor Registrable Shares must
                                    be included in such registration prior to
                                    any other shares of the Company. The Company
                                    shall not register securities for sale for
                                    its own account in any registration
                                    requested pursuant to this Section 3 unless
                                    permitted to do so by the written consent of
                                    Investor Holders who hold at least 75% of

                                      -11-
<PAGE>   12
                                    the Investor Registrable Shares as to which
                                    registration has been requested.

         3.7.     Subject to the provisions of Section 3.1, the Company may not
                  cause any other registration of securities for sale for its
                  own account (other than a registration effected solely to
                  implement an employee benefit plan) to be initiated after a
                  registration requested pursuant to Section 3 and to become
                  effective less than 90 days after the effective date of any
                  registration requested pursuant to Section 3.

         3.8.     F-3 Registration. Commencing as soon as legally permissible
                  after the closing of the IPO, in any case that the Company
                  shall receive from any Holder or Holders a written request or
                  requests that the Company effect a registration on Form F-3,
                  and any related qualification or compliance, with respect to
                  Investor Registrable Shares where the aggregate net proceeds
                  from the sale of such Investor Registrable Shares equals to at
                  least five million United States Dollars ($5,000,000), the
                  Company will within twenty (20) days after receipt of any such
                  request give written notice of the proposed registration and
                  any related qualification or compliance, to all other Holders,
                  and include in such registration all Investor Registrable
                  Shares held by all such Holders who wish to participate in
                  such registration and provide the Company with written
                  requests for inclusion therein within 15 days after the
                  receipt of the Company's notice. Thereupon, the Company shall
                  effect such registration and all such qualifications and
                  compliances as may be so requested and as would permit or
                  facilitate the sale and distribution of all or such portion of
                  such Holder's or Holders' Investor Registrable Shares as are
                  specified in such request, together with all or such portion
                  of the Investor Registrable Shares of any other Holder or
                  Holders joining such request as are specified in a written
                  request given within fifteen (15) days after receipt of such
                  written notice from the Company; provided, however, that the
                  Company shall not be obligated to effect any such
                  registration, qualification, or compliance, pursuant to this
                  Section 3.8 if the Company has, within the twelve (12) month
                  period preceding the date of such request, already effected
                  two (2) registrations for the Holders pursuant to this Section
                  3.8. The Company undertakes that it will, once having
                  qualified for registration on Form F-3, use its best efforts
                  to comply with all necessary filings and other requirements so
                  as to maintain such qualification.

         3.9.     Additional F-3. The provisions of this Section 3
                  notwithstanding, in the event that all three (3) Demands
                  available pursuant to Section 3.1 are utilized and Holders of
                  at least 75% of either the (i) unregistered Series A and B
                  Investor Registrable Shares (the "DISSENTING SERIES A AND B
                  INVESTORS"), (ii) unregistered Series C Investor Registrable
                  Shares (the "DISSENTING SERIES C INVESTORS") or (iii)
                  unregistered Series D Investor Registrable Shares (the
                  "DISSENTING SERIES D INVESTORS") elect not to participate in
                  any such Demand then the Dissenting Series A and B Investors,
                  the Dissenting Series C Investors and/or the Dissenting Series
                  D Investors, as the case may be, shall each be entitled to an
                  additional demand for an F-3 registration, which F-3
                  registration

                                      -12-

                  shall be effected in accordance with the terms of Section 3.8,
                  with such changes as the context may require.

         3.10.    The Company shall have the right, exercisable once in any 12
                  month period, to defer filing a registration statement (a
                  "REGISTRATION DEFERRAL") under the Securities Act pursuant to
                  this Section 3 for a period of up to 90 days if (i) the Board
                  of Directors of the Company shall determine that it would be
                  seriously detrimental to the Company to file such registration
                  statement at the date the filing would otherwise be required
                  under this Agreement, or (ii) the Board of Directors of the
                  Company determines in good faith that (A) the Company is in
                  possession of material, non-public information concerning an
                  acquisition, merger, recapitalization, consolidation,
                  reorganization or other material transaction by or of the
                  Company or concerning pending or threatened litigation and (B)
                  disclosure of such information would jeopardize any such
                  transaction or litigation or otherwise materially harm the
                  Company, or (iii) at the time of such request the Company is
                  engaged, or has formal plans to engage within 60 days of the
                  time of such request, in an underwritten public offering of
                  securities (including an offering contemplated by Section 3
                  hereof), provided that the Company's right to undertake a
                  registration for its own account contained in Section 3.1
                  shall not be deemed to be an exercise of the provisions of
                  this Section 3.10.

4.       DESIGNATION OF UNDERWRITER.

         4.1.     In the case of any registration effected pursuant to Section
                  3, should the offering be underwritten, the Company and the
                  majority of the Initiating Holders that submitted the request
                  for the Demand registration shall confer as to the selection
                  of a managing underwriter. Should they fail to reach
                  agreement, the selection shall be made by the majority of the
                  Initiating Holders who submitted the Demand request.

         4.2.     In the case of any registration initiated by the Company, the
                  Company shall have the right to designate the managing
                  underwriter in any underwritten offering.

         4.3.       In an IPO, the Company shall use its best efforts to involve
                    Nomura and Nomura shall have the right to act as not less
                    than a co-manager in the underwriters' consortium, with a
                    right to distribute at least 10% of the shares which are
                    subject to the IPO.

5.       EXPENSES.

All expenses incurred in connection with any registration under Sections 2 or 3,
including the reasonable fees of one legal counsel for the selling Holders,
shall be borne by the Company; provided, however, that each of the Holders
participating in such registration shall pay its pro rata portion of the
discounts or commissions payable to any underwriter.

6.       INDEMNIFICATION AND CONTRIBUTION.

In the event of any registered offering of Ordinary Shares pursuant to this
Agreement:

         6.1.     The Company will indemnify and hold harmless, to the fullest
                  extent permitted by law, any Holder and any underwriter for
                  such Holder, and each person, if any, who controls the Holder
                  or such underwriter, from and against any and all losses,
                  damages, claims, liabilities, joint or several, costs and
                  expenses (including any amounts paid in any settlement
                  effected with the Company's prior written consent) to which
                  the Holder or any such underwriter or controlling person may
                  become subject under applicable law or otherwise, insofar as
                  such losses, damages, claims, liabilities (or actions or
                  proceedings in respect thereof), costs or expenses arise out
                  of or are based upon (i) any untrue statement or alleged
                  untrue statement of any material fact contained in the
                  registration statement or included in the prospectus, as
                  amended or supplemented, or (ii) the omission or alleged
                  omission to state therein a material fact required to be
                  stated therein or necessary to make the statements therein, in
                  the light of the circumstances in which they are made, not
                  misleading, and the Company will reimburse the Holder, such
                  underwriter and each such controlling person of the Holder or
                  the underwriter, promptly upon demand, for any reasonable
                  legal or any other expenses incurred by them in connection
                  with investigating, preparing to defend or defending against
                  or appearing as a third-party witness in connection with such
                  loss, claim, damage, liability, action or proceeding;
                  provided, however, that the Company will not be liable in any
                  such case to the extent that any such loss, damage, liability,
                  cost or expense arises out of or is based upon an untrue
                  statement or omission in such registration statement or
                  prospectus so made in conformity with information furnished to
                  the Company in writing by a Holder, such underwriter or such
                  controlling persons specifically for use in such registration
                  statement; provided, further, that this indemnity shall not be
                  deemed to relieve any underwriter of any of its due diligence
                  obligations; provided, further, that the indemnity agreement
                  contained in this Section 6.1 shall not apply to amounts paid
                  in settlement of any such claim, loss, damage, liability or
                  action if such settlement is effected without the consent of
                  the Company, which consent shall not be unreasonably withheld.
                  Such indemnity shall remain in full force and effect
                  regardless of any investigation made by or on behalf of the
                  selling Shareholder, the underwriter or any controlling person
                  of the selling Shareholder or the underwriter, and regardless
                  of any sale in connection with such offering by the selling
                  Shareholder. Such indemnity shall survive the transfer of
                  securities by a selling Shareholder; or (iii) indemnification
                  of shareholders against any violation or alleged violation by
                  the Company of the Securities Act of 1933, Securities Exchange
                  Act of 1934 or the state securities laws of individual U.S.
                  states.

         6.2.     Each Holder participating in a registration hereunder will
                  indemnify and hold harmless the Company, any underwriter for
                  the Company, and each person, if any, who controls the Company
                  or such underwriter, from and against any and

                                      -14-
<PAGE>   15
                  all losses, damages, claims, liabilities, costs or expenses
                  (including any amounts paid in any settlement effected with
                  the selling Shareholder's consent) to which the Company or any
                  such controlling person and/or any such underwriter may become
                  subject under applicable law or otherwise, insofar as such
                  losses, damages, claims, liabilities (or actions or
                  proceedings in respect thereof), costs or expenses arise out
                  of or are based on (i) any untrue statement or alleged untrue
                  statement of any material fact contained in the registration
                  statement or included in the prospectus, as amended or
                  supplemented, or (ii) the omission or alleged omission to
                  state therein a material fact required to be stated therein or
                  necessary to make the statements therein, in the light of the
                  circumstances in which they were made, not misleading, and
                  each such Holder will reimburse the Company, any underwriter
                  and each such controlling person of the Company or any
                  underwriter, promptly upon demand, for any reasonable legal or
                  other expenses incurred by them in connection with
                  investigating, preparing to defend or defending against or
                  appearing as a third-party witness in connection with such
                  loss, claim, damage, liability, action or proceeding;
                  provided, however, notwithstanding the foregoing terms of this
                  Section 6.2, that the Holder shall be liable in any such case
                  only to the extent that any such loss, damage, liability, cost
                  or expense arises out of or is based upon an untrue statement
                  or omission in such registration or prospectus made in strict
                  conformity with written information furnished to the Company
                  by such Holder specifically for use in such registration
                  statement; and provided further that the liability of such
                  Holder under this Section 6.2, excluding liability for costs
                  and expenses arising out of any action or proceeding, shall
                  not exceed the product of the number of shares registered by
                  the Holder and the per share purchase price of the shares as
                  set forth in the registration; provided, further, that this
                  indemnity shall not be deemed to relieve any underwriter of
                  any of its due diligence obligations; provided, further, that
                  the indemnity agreement contained in this Section 6.2 shall
                  not apply to amounts paid in settlement of any such claim,
                  loss, damage, liability or action if such settlement is
                  effected without the consent of the Holders, as the case may
                  be, which consent shall not be unreasonably withheld. In no
                  event shall the liability of a Holder exceed the gross
                  proceeds from the offering received by such Holder.

         6.3.     Promptly after receipt by an indemnified party pursuant to the
                  provisions of Sections 6.1 or 6.2 of notice of the
                  commencement of any action involving the subject matter of the
                  foregoing indemnity provisions, but in any event no fewer than
                  ten (10) days before the date designated in such notice as the
                  date by which an answer must be served (or such extension
                  thereof, provided that the extension has been granted in
                  writing by the plaintiff and that no admission or consent to
                  jurisdiction or other waiver has been granted or implied by
                  the request for such an extension), such indemnified party
                  will, if a claim thereof is to be made against the
                  indemnifying party pursuant to the provisions of said Sections
                  6.1 or 6.2, promptly notify the indemnifying party of the
                  commencement thereof In

                                      -15-
<PAGE>   16
                  case such action is brought against any indemnified party and
                  it notifies the indemnifying party of the commencement
                  thereof, the indemnifying party shall have the right to
                  participate in, and, to the extent that it may wish, jointly
                  with any other indemnifying party similarly notified, to
                  assume the defense thereof with counsel reasonably
                  satisfactory to such indemnified party; provided, however,
                  that if the defendants in any action include both the
                  indemnified party and the indemnifying party and there is a
                  conflict of interests which would prevent counsel for the
                  indemnifying party from also representing the indemnified
                  party, the indemnified party or parties shall have the right
                  to select one separate counsel to participate in the defense
                  of such action on behalf of such indemnified party or parties.
                  After notice from the indemnifying party to such indemnified
                  party of its election so to assume the defense thereof, the
                  indemnifying party will not be liable to such indemnified
                  party pursuant to the provisions of said Sections 6.1 or 6.2
                  for any legal or other expense subsequently incurred by such
                  indemnified party in connection with the defense thereof,
                  unless (i) the indemnified party shall have employed counsel
                  in accordance with the provision of the preceding sentence,
                  (ii) the indemnifying party shall not have employed counsel
                  reasonably satisfactory to the indemnified party to represent
                  the indemnified party within a reasonable time after the
                  notice of the commencement of the action and within 15 days
                  after written notice of the indemnified party's intention to
                  employ separate counsel pursuant to the previous sentence, or
                  (iii) the indemnifying party has authorized the employment of
                  counsel for the indemnified party at the expense of the
                  indemnifying party. No indemnifying party will consent to
                  entry of any judgment or enter into any settlement which does
                  not include as an unconditional term thereof the giving by the
                  claimant or plaintiff to such indemnified party of a release
                  from all liability in respect to such claim or litigation.

         6.4.     Contribution. If for any reason the foregoing indemnity is
                  unavailable, or is insufficient to hold harmless an
                  indemnified party, then the indemnifying party shall
                  contribute to the amount paid or payable by the indemnified
                  party as a result of such losses, claims, damages, liabilities
                  or expenses (i) in such proportion as is appropriate to
                  reflect the relative benefits received by the indemnifying
                  party on the one hand and the indemnified party on the other
                  from the registration or (ii) if the allocation provided by
                  clause (i) above is not permitted by applicable law, or
                  provides a lesser sum to the indemnified party than the amount
                  hereinafter calculated, in such proportion as is appropriate
                  to reflect not only the relative benefits received by the
                  indemnifying party on the one hand and the indemnified party
                  on the other but also the relative fault of the indemnifying
                  party and the indemnified party as well as any other relevant
                  equitable considerations; provided that in no event shall any
                  contribution by a Holder hereunder exceed the gross proceeds
                  from the offering received from such Holder. 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.

7.    OBLIGATIONS OF THE COMPANY.

Whenever required under this Agreement to effect the registration of any
Registrable Shares, the Company shall, as expeditiously as possible:

      7.1.   (i) prepare and file with the SEC a registration statement with
             respect to such Registrable Shares and use its best efforts to
             cause such registration statement to become effective, (ii) upon
             the request of the holders of a majority of the Registrable
             Shares registered thereunder, keep a registration statement
             filed pursuant to Section 2 effective for a period of up to two
             hundred seventy (270) days  or, if sooner, until the
             distribution contemplated in the Registration Statement has been
             completed, and (iii) upon the request of the holders of a
             majority of the Investor Registrable Shares registered
             thereunder, keep a registration statement filed pursuant to
             Section 3 above effective for a period of up to two hundred
             seventy (270) days or, if sooner, until the distribution
             contemplated in the Registration Statement has been completed,
             provided, that the in the case of the First Demand, the Company
             shall not be obligated to keep the registration statement filed
             pursuant thereto effective for more than one hundred and eighty
             (180) days or, in the event such First Demand is underwritten,
             for more than the period within which the distribution
             contemplated in the registration statement has been completed,
             and further provided, that in the event that the First Demand is
             not underwritten, no Holder may sell shares pursuant to the
             registration statement effective pursuant to the First Demand
             without first inquiring of the Company in writing as to whether
             such sale would be permissible at such time in light of the then
             current form of such registration statement.  Failure by the
             Company to respond in writing to an address or fax number
             provided by the inquiring shareholder in its inquiry within
             three days of the request shall be deemed to be assent to such
             proposed sale.  In the event that the Company does inform the
             inquiring shareholder that the proposed sale of securities under
             the relevant registration statement would not be permissible at
             such time, then the Company shall use its best efforts to amend
             or supplement such registration statement or the prospectus
             included therein so that such shareholder can sell its
             securities thereunder unless (i) the Board of Directors of the
             Company determines that it would be seriously detrimental to the
             Company to so amend or supplement such registration statement or
             prospectus, or (ii) the Board of Directors of the Company
             determines in good faith that (A) the Company is in possession
             of material, non-public information concerning an acquisition,
             merger, recapitalization, consolidation, reorganization or other
             material transaction by or of the Company or concerning pending
             or threatened litigation and (B) disclosure of such information
             would jeopardize any such transaction or litigation or otherwise
             materially harm the Company.  In any such event, the Company
             shall promptly notify the inquiring holder when the use of the
             relevant registration statement or prospectus may be resumed or
             supply such holder with copies of any amendment or supplement
             made pursuant

                                      -17-
<PAGE>   18
             to the preceding sentence and such inquiring holder shall not
             dispose of its Registrable Shares under such registration statement
             or prospectus until it is so advised in writing by the Company that
             the use of the prospectus included in such registration statement
             may be resumed or until such holder receives such copies of any
             supplement or amendment to such registration statement or

             be in effect for more than 90 days in any 12 month period.

             such registration statement and the prospectus used in connection

             the disposition of all Registrable Shares covered by such
             registration statement.

             the happening of any event as a result of which the prospectus
             included in such registration statement, as then in effect,
             includes an untrue statement of a material fact or omits to
             state a material fact required to be stated therein or necessary
             to make the statements therein not misleading in the light of
             the circumstances then existing, in which event each such holder
             of Registrable Shares shall forthwith discontinue disposition of
             its Registrable Shares pursuant to such prospectus until it is
             advised in writing by the Company that the use of such
             prospectus may be resumed or until such holder receives copies
             of any supplement or amendment to such prospectus, provided,

             general consent to service of process, in any state.

      7.9.   furnish, at the request of any Holder requesting registration of

16. PRE-EMPTIVE RIGHT.

      16.1.  Prior to the consummation of a Qualified IPO, if the Company
             proposes to issue or sell any New Securities (as defined in
             Section 16.2.1), the Company shall, before such issuance, offer
             to all shareholders (collectively the "Offered Shareholders")
             the right to purchase a pro-rata share of the New Securities.  A
             shareholder's pro-rata share, for purposes of this Section, is
             the ratio of the number of issued shares owned by such
             Shareholder immediately prior to the issuance of New Securities
             (treating all Preferred Shares as if fully converted), to the
             total number of shares outstanding immediately prior to the
             issuance of New Securities (treating all of the Preferred Shares
             as if fully converted).

             Each holder of Preferred Shares shall have a right of
             over-allotment such that if any of the holders of Preferred Shares
             fails to exercise its right hereunder to purchase its pro-rata
             share of New Securities, the other Investors holding Preferred
             Shares may purchase the portion of the non-purchasing shareholder
             pro-rata according to the shareholding ratio between such other
             shareholders of Preferred Shares, within five (5) days from the
             date such non-purchasing holder of Preferred Shares fails to
             exercise its rights hereunder to purchase its pro-rata share of New
             Securities.

             Each one of the Founders shall have a right of over-allotment such
             that if any of the holders of Ordinary Shares fails to exercise its
             right hereunder to purchase its pro-rata share of New Securities,
             each Founder may purchase the portion of the non-purchasing
             shareholder pro-rata according to the shareholding ratio between
             the Founders within five (5) days from the date such non-purchasing
             holder of

                                      -28-
<PAGE>   29
             Ordinary Shares fails to exercise its rights hereunder to purchase
             its pro-rata share of New Securities.

      16.2.  This pre-emptive right shall be subject to the following
             provisions:

             16.2.1.  "NEW SECURITIES" shall mean any equity interest
                      (including Ordinary and Preferred Shares) in the
                      Company, whether now authorized or not, and rights,
                      options or warrants to purchase such equity interests,
                      and securities of any type whatsoever that are
                      convertible into equity interests; provided that the
                      term "New Securities" does not include: (i) securities
                      issued upon the conversion of the Preferred Shares or
                      conversion of the Option Shares and (ii) securities
                      issued, pursuant to a resolution of the Board of
                      Directors, to employees, directors or consultants of
                      the Company, subsidiary or parent of the Company, who
                      hold less than 5% of the Company's issued and
                      outstanding share capital; and (iii) securities issued
                      in a Qualified IPO; and (iv) securities issued in
                      connection with stock split, stock dividend or other
                      recapitalization events in the Company; (v) Preferred C
                      Shares issuable upon the exercise of the Warrants (as
                      defined, and under the terms set forth, in the SPA) or
                      any other shares issuable pursuant to other warrants
                      outstanding as of February 8, 2000and (vi) securities,
                      in an amount not exceeding, in the aggregate, 10% of
                      the issued and outstanding share capital of the
                      Company, issued to a Strategic Investor on or after
                      January 1, 2000.  "Strategic Investor" shall mean an
                      entity  which, in the determination of the majority of
                      the Board of Directors (including the approval of all
                      of the Directors appointed pursuant to Section 15.1.2,
                      15.1.3 and 15.1.4) is capable of materially
                      contributing directly or indirectly to the Company's
                      business other than by investing capital in the Company.

             16.2.2.  In the event the Company proposes to undertake an
                      issuance of New Securities, it shall give each Offered
                      Shareholder written notice of its intention, describing
                      the type of New Securities, and their price and the
                      terms upon which the Company proposes to issue the
                      same.  Each Offered Shareholder shall have seven (7)
                      days after any such notice is delivered to agree to
                      purchase such Offered Shareholder's pro rata share of
                      such New Securities for the price and upon the terms
                      specified in the notice by giving written notice to the
                      Company and stating therein the quantity of New
                      Securities to be purchased.

             16.2.3.  In the event the Offered Shareholders fail to exercise
                      fully the pre-emptive right within the said seven (7)
                      day period the Company shall have one hundred twenty
                      (120) days thereafter to sell or enter into an
                      agreement to sell the New Securities respecting which
                      the Offered Shareholders' pre-emptive right set forth
                      in this Section is not

             of the Founders and/or their Permitted Transferees shall be

             the shares in the Company held by the Founder as of the date
             hereof, without the prior written consent of the holders of 75%
             or more of each of (i) the Preferred A Shares, (ii) the
             Preferred B Shares, (iii) the Preferred C Shares and (iv) the
             Preferred D Shares.

      17.3.  The Founders shall be entitled to transfer or sell shares to their
             Permitted Transferees, provided that the Permitted Transferee
             agrees to be bound to the provisions of this Agreement and the
             Company's Articles of Association.

      17.4.  In the event that a Founder or any of his Permitted Transferees
             should sell any shares in contravention of this Agreement, such
             transfer shall be deemed null and void and the Investors may
             proceed to protect and enforce their rights by suit in equity or
             by action at law, whether for the specific performance of any
             term contained in this Agreement or for an injunction against
             the breach of any such term or in furtherance of the exercise of
             any power granted in this Agreement, or to enforce any other
             legal or equitable right of the Investors or to take one or more
             of such actions.

18.   RIGHT OF FIRST REFUSAL.

      18.1.  In the event that any shareholder(s) of the Company (the "Selling
             Shareholder") desires to sell or transfer any or all of its shares
             to any party other than a Permitted Transferee (the "Offered
             Shares"), it shall first give written notice

                                      -30-
<PAGE>   31
             thereof ("Notice of Sale") to all other shareholders (collectively
             the "Option Holders").

      18.2.  The Notice of Sale shall state the number of Offered Shares,
             whether the Offered Shares will, upon the sale, be free of all
             liens, charges and encumbrances, that a bona fide offer has been
             received from a third party, the identity of the third party,
             and the price and terms of payment for the Offered Shares.  Upon
             receipt of the Notice of Sale, the Option Holders shall have the
             right to exercise the option (the "Option") contained in
             Sections 18.3 and 18.4.

      18.3.  For a period of 20 days after receipt of the Notice of Sale, the
             Option Holders collectively may elect to purchase all (but not
             part) of the Offered Shares (those Option Holders which exercise
             the Option are referred to as the "Buying Shareholders").  The
             Option shall be exercised by delivery of a notice by one or more
             of the Buying Shareholders to the Selling Shareholder within the
             aforesaid 20-day period stating (i) that the Buying Shareholder
             intends to acquire its pro rata share of the Offered Shares,
             according to the shareholding ratio between the Option Holders
             as of the date immediately prior to sending such notice; and
             (ii) in the event that the Selling Shareholder receives notices
             from Buying Shareholders to buy some, but not all, of the
             Offered Shares, how many additional Offered Shares the Buying
             Shareholder intends to acquire of the Offered Shares remaining
             as a result of the failure of all Buying Shareholders to offer
             to buy their pro rata share (the "Remaining Offered Shares").

      18.4.  If the Selling Shareholder receives notices from all Option
             Holders that they wish to exercise the Option, then the Buying
             Shareholders shall acquire the Offered Shares pro rata,
             according to the shareholding ratio between the Option Holders
             as of the date immediately prior to sending their notices.  If
             the Selling Shareholder receives notices from Buying
             Shareholders to buy some, but not all, of the Offered Shares and
             the notices of the Buying Shareholders indicate that the Buying
             Shareholders intend to buy a number of additional Offered Shares
             equal to or greater than the number of the Remaining Offered
             Shares, then (i) the Buying Shareholders shall each acquire that
             percentage of the Offered Shares which corresponds to its
             percentage ownership of the shares held by the Option Holders as
             of the date immediately prior to sending their notices and (ii)
             the Buying Shareholders shall acquire the Remaining Offered
             Shares pro rata according to the number of additional Offered
             Shares that each Buying Shareholder offered to acquire in its
             notice.  The purchase of the Offered Shares shall be on the same
             terms and conditions as stated in the Notice of Sale.

      18.5.  If the notices of the Buying Shareholders indicate that the
             Buying Shareholders have not elected to purchase all of the
             Offered Shares, then the Selling Shareholder shall be free,
             within 90 days of the date of expiration of the Option, to sell
             such shares at the price and on the terms contained in the
             Notice of Sale.  If there is no sale within such 90 day period,
             the Selling Shareholder shall not

                                      -31-
<PAGE>   32
             sell or transfer the Offered Shares, or any other shares acquired
             before or after the date hereof, without again complying with the
             provisions of this section.

      18.6.  In the event that there is a situation in which fractional shares
             will need to be transferred, the number of shares will be rounded
             up so that only full shares will be transferred.

      18.7.  The provisions of this Section shall terminate on and not apply to
             a Qualified IPO.

      18.8.  Any provision of this Section  to the contrary notwithstanding,
             any offering of  Preferred C Shares shall first be made to the
             other holders of such shares, and the provisions of this
             Section  shall apply to such offering, mutatis mutandis. In the
             event that there shall be any remaining Preferred C Shares which
             will not be purchased as aforesaid, such shares shall be offered
             to the other Shareholders of the Company, as set forth in this
             Section.

      18.9.  Any provision of this Section  to the contrary notwithstanding,
             any offering of  Preferred D Shares shall first be made to the
             other holders of such shares, and the provisions of this
             Section  shall apply to such offering, mutatis mutandis. In the
             event that there shall be any remaining Preferred D Shares which
             will not be purchased as aforesaid, such shares shall be offered
             to the other Shareholders of the Company, as set forth in this
             Section.

      18.10. Any provision of this Section to the contrary notwithstanding, in
             no event shall any transfer of shares of the Company be effected if
             the third party transferee (which is not a shareholder who
             exercised its right of first refusal as set forth herein) is in
             competition, directly or indirectly, with the Company, as
             determined by the Board of Directors of the Company.

            Any transfer of shares of the Company or of any rights associated
            herewith or granted hereunder shall be effective only if such
            transfer is effected in accordance with the provisions of the then
            current Articles of Association of the Company, which relate to the
            transfer of shares of the Company (including the granting of a right
            of first refusal to holders of shares in the Company).

19.   INVESTOR TAG-ALONG RIGHTS.

      19.1.  If (i) any of the Founders or their Permitted Transferees is the
             Selling Shareholder (the "Selling Insider"), (ii) the sale is not
             to a Permitted Transferee of the Founder, and (iii) all of the
             Offered Shares are not sold to the Buying Shareholders pursuant to
             Section 18 above, then the provisions of this Section 19 shall
             apply.

      19.2.  The Selling Insider shall so notify the other Option Holders,
             describing in such notification the material terms of such proposed
             sale. Upon receipt of such

                                      -32-
<PAGE>   33
             notice, each of the other Option Holders shall have the right to
             exercise the option contained in Section 19.3 below.

      19.3.  Each of the other Option Holders shall have the option,
             exercisable by written notice to the Selling Insider, within 10
             business days after receipt of the notice described in Section
             above, to require the Selling Insider to provide as part of his
             proposed sale that each of the other Option Holders be given the
             right to participate, on the same terms and conditions as the
             Selling Insider, in the sale pro rata in proportion to the
             respective numbers of Shares owned at such time by the Selling
             Insider and all Option Holders who participate in the proposed
             sale.

      19.4.  Notwithstanding the aforesaid, if any of the Founders or their
             Permitted Transferees shall sell shares of the Company in a
             transaction or series of transactions which result in a change in
             control of the Company, the Investors shall have the right to
             participate in such transaction and to sell all of their shares in
             the Company in that transaction.

      19.5.  Notwithstanding Sections 19.1 through 19.3, each Founder shall be
             permitted to sell, free of the limitations of Sections through
             19.3, the number of shares which represents 5% of the shares in the
             Company held by the Founder as of August 24, 1998.

      19.6.  The provisions of this Section 19 shall terminate on a Qualified
             IPO.

20. BRING-ALONG.

Notwithstanding anything to the contrary in this Agreement including in Section
18 and 19 herein above, at any time prior to the Company's Qualified IPO, in the
event that (i) one or more bona fide offers from any third party person or
entity (the "Offeror") is made to purchase shares and, (ii) such sale is
conditioned upon the sale of all of the remaining issued shares of the Company
to the Offeror, and (iii) shareholders holding 85% (eighty-five percent) of the
Company's outstanding share capital (the "Proposing Shareholders") propose to
sell all of their shares to such Offeror, then all remaining shareholders (the
"Non-Proposing Shareholders") will be required, if so demanded by the Proposing
Shareholders, to sell their Shares to such Offeror at the same price and upon
the same terms and conditions as in the offer made to the Proposing
Shareholders. In such event, any sale, assignment, transfer, pledge,
hypothecation, mortgage, disposal or encumbrance of shares by the Non-Proposing
Shareholders other than in connection with the proposed acquisition shall be
absolutely prohibited.

21.   INTENTIONALLY  DELETED

22.   AMENDMENT

Any term of this Agreement may be amended and the observance of any term hereof
may be waived (either prospectively or retroactively and either generally or in
a particular instance) with

<PAGE>   34
the written consent of the Founders and the holders of 75% of each of the issued
and outstanding (i) Preferred A Shares, (ii) Preferred B Shares, (iii) Preferred
C Shares and (iv) Preferred D Shares, of the Company.

23.    MISCELLANEOUS

      23.1.  Further Assurances. Each of the parties hereto shall perform such

             except as set forth in Section 9 above and except that, upon the
             consummation of a transfer of shares to a Permitted Transferee
             and such Permitted Transferee's agreement in writing to be bound
             by and assume all obligations of the transferor (as a

             no assignment or transfer under this Section 23.3 shall be made
             unless the transferee agrees to be bound by all agreements binding
             upon the Shareholders immediately prior to such transfer.

      23.4.  Entire Agreement. This Agreement constitutes the full and entire
             understanding and agreement between the parties with regard to the
             subject matter hereof. This Agreement amends and replaces the SRA.

      23.5.  Section Headings; Preamble. All article and section headings are
             inserted for convenience only and shall not modify or affect the
             construction or interpretation of any provision of this Agreement.

             integral part of this Agreement.

             time to time by notice from any Shareholder.

      23.7.  Delays or Omissions. No delay or omission to exercise any right,
             power, or remedy accruing to any party upon any breach or
             default under this Agreement, shall be deemed a waiver of any
             other breach or default theretofore or thereafter occurring. Any
             waiver, permit, consent, or approval of any kind or character on
             the part of any party of any breach or default under this
             Agreement, or any waiver on the part of any party of any
             provisions or conditions of this Agreement, must be in writing
             and shall be effective only to the extent specifically set forth
             in such writing. All remedies, either under this Agreement or by
             law or otherwise afforded to any of the parties, shall be
             cumulative and not alternative.

      23.8.  Severability. If any provision of this Agreement is held by a
             court of competent jurisdiction to be unenforceable under
             applicable law, then such provision shall be excluded from this
             Agreement and the remainder of this Agreement shall be
             interpreted as if such provision were so excluded and shall be
             enforceable in accordance with its terms; provided, however,
             that in such event this Agreement shall be interpreted so as to
             give effect, to the greatest extent consistent with and
             permitted by applicable law, to the meaning and intention of the
             excluded provision as determined by such court of competent
             jurisdiction.

      23.9.  Counterparts. This Agreement may be executed in any number of
             counterparts, each of which shall be deemed an original and
             enforceable against the parties actually executing such
             counterpart, and all of which together shall constitute one and the
             same instrument.

      23.10. Waiver of Veto Rights. Except as expressly provided herein, each
             Investor executing this Agreement expressly waives any veto right
             or negative covenant which it possesses in any organ of the Company
             as to any of the matters covered by this Agreement.

      23.11. For purposes of determining the availability of any right or the
             applicability of any limitation under this Agreement, all Preferred
             C Shares, or any other securities, held or acquired by any IIF
             Investor shall be aggregated, and the IIF Investors and any such
             transferees be viewed as a single Investor or shareholder, as
             applicable.

                                      -35-
