primarily in the United States and co-own and have co-developed an electronic

European market;

               WHEREAS, the Venturers have heretofore formed the 


JV Companies for the purpose of developing and exploiting EuroPOSIT for use in

certain contributions to the Company of working capital, to provide for the
management of the Company and for certain restrictions on the transferability of
their respective Equity Interests in the Company, among other things, all in
furtherance of the objectives set forth above and subject to the terms and
conditions hereinafter set forth.

to ITGL in the form of loans as set forth in Schedule 3.1.

       3.2     CONTRIBUTIONS TO THE COMPANY.  Except as otherwise expressly 
provided in this Agreement, no Venturer shall be required to make any 
contributions to the capital of the Companies or subscribe for additional 
shares of the equity securities of the JV Companies.

       3.3     INITIAL CAPITAL CONTRIBUTIONS OF THE VENTURERS.  On or prior 
to the November 30 1998, each Venturer shall have made initial capital 
contributions to the Company consisting of GBL2,900,000 in exchange for 
50,000 Class A Voting Ordinary Shares and GBL2,850,000 Non-Share Capital. 

       3.4     ADDITIONAL CAPITAL CONTRIBUTIONS OF THE VENTURERS. 
               (a)    From and after the date hereof, the Company may require
(each such requirement, a "Capital Call") each Venturer to make additional 
cash capital contributions ("Additional Capital Contributions") to the 
Company (i) of up to an aggregate of GBL2,100,000, in such increments and at 
such times as contemplated by the Schedule of Capital Calls, or as may 
otherwise be approved by the Company Board, and (ii) in such amounts and at 
such times as may be set forth in Approved Annual Budgets, it being 
understood that the Venturer's Additional Capital Contributions shall be made 
in GB Pounds Sterling by wire transfer of immediately available funds and, 
except as otherwise provided in Section 3.5, each Venturer's Additional 
Capital Contributions shall be made in equal amounts.

               (b)    If the Company determines to make a Capital Call, the
Company shall send to each Venturer a notice thereof (a "Capital Call Notice"),
which shall set forth, among other things, (i) the amount of the Additional
Capital Contribution to be made by each of the Venturers, (ii) the period (the
"Capital Call Period") within which such Additional Capital Contribution shall
be made, which period shall not end less than ten (10) Business Days after the
date on which such Capital Call Notice is given, and (iii) its determination as
to whether such Additional Capital Contribution will be in the form of 




Equity Share Capital, Non-Share Capital or Subordinated Debt.  Upon receipt 
of Additional Capital Contributions in the form of Equity Share Capital from 
a Venturer, the Company shall issue to such Venturer shares of Class B 
Non-Voting Ordinary Shares based on the per share value of the Ordinary 
Shares as determined by the Company Board at the time of the Capital Call.  
Upon receipt of Additional Capital Contributions in the form of Subordinated 
Debt from a Venturer, the Company shall issue to such Venturer a promissory 
note evidencing such indebtedness having such terms and provisions (including 
maturity, interest rate and events of default) as determined by the Company 
Board at the time of the Capital Call.  Any Additional Capital Contributions 
in the form of Non-Share Capital received from a Venturer shall be recorded 
in the books and records of the Company but the Company shall not issue any 
certificate or other instrument to such Venturer in respect thereof.

       3.5     FAILURE TO MAKE ADDITIONAL CAPITAL CONTRIBUTIONS. 

               (a)    Following the expiration of a Capital Call Period, the
Company shall promptly notify each Venturer of the failure by any Venturer (a 
"Defaulting Venturer") to make its respective Additional Capital Contribution 
pursuant to the Capital Call Notice (such failure to make an Additional 
Capital Contribution is referred to herein as a "Funding Breach").  The 
Defaulting Venturer shall have thirty (30) days (the "Cure Period") from the 
date of notice of the Funding Breach to cure such Funding Breach by 
delivering to the Company the Additional Capital Contribution required under 
the Capital Call Notice together with interest thereon calculated at the 
Applicable Rate from the date of the Funding Breach to and including the date 
of payment.  If the Funding Breach is so cured, the Defaulting Venturer shall 
be entitled to receive, and the Company shall issue to the Defaulting 
Venturer, the Class B Non-Voting Shares, promissory note evidencing 
Subordinated Debt or credit on the Company's books and records for Non-share 
Capital to which the Defaulting Venturer would have otherwise been entitled 
to receive under Section 3.4(b) upon the making of the applicable Capital 
Call.

               (b)    If a Defaulting Venturer shall fail to deliver its
Additional Capital Contribution together with interest thereon as provided in
Section 3.5(a) within the Cure Period, then a funding default (a "Funding
Default") shall have occurred and all rights of the Defaulting Venturer to make
an Additional Capital Contribution pursuant to such Capital Call shall cease
and, for a period of ninety (90) days after the occurrence of the Funding
Default, the 




non-defaulting Venturer (the "Non-Defaulting Venturer") shall have the option 
to provide all or any part of the Defaulting Venturer's Additional Capital 
Contribution to the Company without payment of any interest.  Upon receipt of 
an Additional Capital Contribution pursuant to this Section 3.5(b) by a 
Non-Defaulting Venturer, the Non-Defaulting Venturer shall be entitled to 
receive, and the Company shall issue to the Non-Defaulting Venturer, a number 
of Class B Non-Voting Shares as would reflect the additional Equity Interest 
to which such Non-Defaulting Venturer would be entitled (with any excess of 
the amount contributed over the number of Class B Non-Voting Shares so issued 
to be credited to a share premium account).  To the extent that the issuance 
of such shares results in any adjustment of the Percentage Interests, the 
governance rights of the Venturers under this Agreement shall not be affected.

       3.6     LOANS.  (a)    Except as provided in Section 3.4 or 3.6(c), no 
Venturer shall be obligated to loan funds to any JV  Company.  Loans by a 
Venturer to the Company shall not be considered capital contributions.  The 
amount of any such loans shall be a debt of the Company owed to such Venturer 
in accordance with the terms and conditions upon which such loans are made.

               (b)    With the prior written consent of the other Venturer, a 
Venturer may (but shal not be obligated to) guarantee a loan made to the JV 
Companies.  If a Venturer guarantees a loan made to any JV Company and it is 
required to make payment pursuant to such guarantee to the maker of the loan, 
then the amounts so paid to the maker of the loan shall be treated as a loan 
by such Venturer to the JV Company repayable on demand and not as an 
Additional Capital Contribution.  In the event that only one of the Venturers 
provides such a guarantee, the other Venturer hereby agrees to indemnify the 
Venturer who provides such guarantee for fifty percent (50%) of any amounts 
paid under such guarantee and for fifty percent (50%) of any other costs, 
liabilities or expenses incurred in respect thereof.

               (c)    It is the intention of the Venturers that the JV 
Companies be financed in a manner that enables the JV Companies to have a 
Debt to Equity ratio that enables them to fulfill any regulatory capital 
requirements imposed on the JV Business under the Applicable Laws of any 
Territory in which the JV Companies are conducting or intend to conduct JV 
Business.  To the extent necessary to maintain such regulatory capital 
requirements, the Venturers may in 



their discretion loan such funds as may be necessary to the JV Companies, 
each Venturer shall participate in such loans on a PRO RATA basis based on 
its Percentage Interest at the time such loans are made and, as necessary, 
the Venturers shall enter into intercreditor agreements to ensure that such 
loans shall be subordinate in right of payment to any Senior Debt of the JV 
Companies from time to time.

       3.7     PRE-EMPTIVE RIGHTS.  The Company shall not issue any equity 
securities or any warrant, option or other security convertible into or 
exercisable for such equity securities of the Company (other than any 
issuance of shares of Class A Voting Ordinary Shares as described in Section 
3.1(b) and any shares of Class B Non-Voting Ordinary Shares as contemplated 
by Sections 3.1(a), 3.4 and 3.5), or enter into any agreement in respect of 
such issuance, unless the issuance has been approved as required by this 
Agreement and pursuant to which the Company offers to each of the Venturers 
the right to participate proportionately according to the Percentage Interest 
of such Venturer, as of the date of such proposed issuance, on the same terms 
and conditions, unless otherwise approved by the Executive Committee.  Any 
right granted pursuant to the preceding sentence shall be exercised by 
written notice to the Company given within thirty (30) days after delivery to 
each Venturer of written notice of such proposed issuance.  If any Venturer 
fails to respond to the Company within the 30-day notice period, such failure 
shall be deemed to be the rejection of the right of such Venturer to 
participate in the purchase of the equity of the Company to be issued.  At 
any time within ninety (90) days following the date the Company has received 
notice (or deemed rejection) from each Venturer accepting or rejecting its 
right to participate, the Company may carry out the proposed issuance.  The 
provisions of this Section 3.7 shall not apply to an issuance of Equity Share 
Capital of the Company or any other Equity Interest in the Company, including 
without limitation any warrant, option or security convertible into or 
exercisable for such Equity Share Capital in connection with a Public 
Offering, an acquisition completed in the ordinary course of the JV Business 
or an employee benefit plan or incentive compensation plan.

       3.8     DISTRIBUTIONS.  Unless the Venturers mutually otherwise agree 
in writing to permit Distributions at an earlier time or on a different 
basis, the Venturers shall, and shall cause their representatives on the 
Company Board, to take all such action so that the Company shall not make any 
Distributions until such time as profits as accumulated 



since the formation of the Company are in excess of losses as accumulated 
since the formation of the Company as reflected in the annual consolidated 
financial statements prepared for the Company and the Subsidiaries for the 
Financial Year then ended (the first such Financial Year being hereinafter 
referred to as an "Initial Profit Year" and each such subsequent Financial 
Year being hereinafter referred to as a "Profit Year").  Thereupon, the 
Venturers shall cause their representatives on the Company Board, to take all 
such action so that "Distributable Cash" held by the Company, unless 
otherwise determined by the Company Board, shall be distributed as 
Distributions to the Venturers in accordance with their respective Percentage 
Interests at least semi-annually in respect of the preceding six-month 
period; PROVIDED, HOWEVER, that all fees then payable under the Service 
Agreements shall have been paid, as required thereunder prior to any 
Distribution to the Venturers pursuant to this Section. Unless otherwise 
approved by the Company Board, all Distributions to Venturers shall be in 
cash in GB Pounds Sterling.  Distributable Cash shall mean seventy percent 
(70%) of the amount by which cash and cash equivalents (less the Company=s 
debt proceeds and contributions to capital, less, amounts specified in the 
Approved Annual Budget to serve as a source of funds for capital expenditures 
and, less, required amounts needed pursuant to Applicable Law to ensure that 
the Company has sufficient regulatory capital) as shown in the Company=s 
quarterly consolidated statement of cash flows as of the end of the relevant 
fiscal quarter exceeds the cash and cash equivalents as shown in the 
Company=s consolidated statement of cash flows as of the end of the preceding 
fiscal quarter (after taking into account any Distributions as of the end of 
such preceding fiscal quarter).  The Company shall cause its Subsidiaries to 
make Distributions to the Company to the extent necessary to facilitate the 
making of Distributions by the Company as contemplated by this Section 3.8, 
subject to mandatory provisions of Applicable Law.  In no event shall the 
Company or its Subsidiaries make Distributions in excess of amounts permitted 
under Applicable Law.

       3.9     BUSINESS PLAN.  In furtherance of the Joint Venture, the 
Venturers have established the Business Plan which sets forth the manner in 
which the JV Business is to be conducted by the JV Companies during the 
5-year period beginning on the date hereof and embodies the overall business 
strategy for the Joint Venture until such time as 



it may be amended or modified upon the approval of the Company Board.  A true 
and correct copy of the Business Plan on the date hereof is attached hereto 
as SCHEDULE 3.9.

       3.10    PREPARATION OF APPROVED ANNUAL BUDGET.  The Executive 
Committee shall prepare for presentation by the chief executive officer of 
the Company to the Company Board on or before October 31 in each year 
beginning October 31, 1999, an annual budget for the Company and its 
Subsidiaries setting forth in reasonable detail the proposed and projected 
operating revenues and expenses for the Company and its Subsidiaries for the 
year beginning the following January 1. Upon approval of such proposed annual 
budget by the Company Board (with such changes, if any, as the Company Board 
may determine), each annual budget shall constitute an "Approved Annual 
Budget" for purposes hereof.  

       3.11    APPROVED ANNUAL BUDGET FOR INITIAL FINANCIAL YEAR. 
Notwithstanding anything to the contrary contained in Section 3.10, a true 
and correct copy of the Approved Annual Budget for the initial Financial Year 
of the Company and its Subsidiaries is set out in the document attached at 
SCHEDULE 3.9.

               (a)    The Venturers hereby constitute, effective on the date 
hereof, a founders committee (the "Founders Committee") consisting of two 
voting representatives designated by each Venturer.  The voting 
representatives designated by ITGI shall at all times be senior ranking 
officers of ITG, Inc. or its Affiliates and the voting representatives 
designated by SG shall at all times be senior ranking officers of SG 
Securities (London) Ltd. or its Affiliates.  As of the date hereof, the 
voting representatives of the Founders Committee designated by ITGI are 
Raymond L. Killian Jr. and Howard C. Naphtali and the voting representatives 
designated by SG are Hugh Hughes and Yves Tuloup.

               (b)    The Founders Committee will be responsible for (i) 
resolving Deadlocks and (ii) any other matter assigned to the Founders 
Committee pursuant to the terms of this Agreement or any other Operative 
Agreement.

               (c)    Consistent with Section 8.1(b), the Parties agree and 
shall give instructions to their respective representatives on the Founders 
Committee, that the purpose of the Founders Committee is not to engage in 



the management of the JV Companies, which management shall be effected in 
accordance with the Business Plan by the respective JV Boards, the Committees 
and the management of each of the JV Companies without referring, unless 
required pursuant to this Agreement or the other Operative Agreements, such 
matters to the Founders Committee.

               (d)    The Founders Committee shall not operate in accordance 
with the general governance provisions contained in Article 9 and, following 
formation, the Founders Committee shall develop its own procedural guidelines 
for governance, including, without limitation, guidelines for the appointment 
of a chairman or co-chairmen thereof.  The Founders Committee shall not meet 
in Ireland.

       8.2     COMPOSITION AND RESPONSIBILITIES OF THE EXECUTIVE COMMITTEE. 

               (a)    ITGL shall constitute, effective on the date hereof or 
as soon thereafter as reasonably practicable, an executive committee of ITGL 
(the "Executive Committee") consisting of the chief executive officer, deputy 
chairman and chief operating officer of ITGL.  

               (b)    The Parties agree that the purpose of the Executive 
Committee is to establish and resolve matters of policy and not to engage in 
the management of ITGL. 

               (c)    The Executive Committee shall not operate in accordance 
with the general governance provisions contained in Article 9 and, following 
formation, the Executive Committee shall develop its own procedural 
guidelines for governance, including, without limitation, guidelines for 
appointment of a chairman or co-chairmen thereof.

       8.3     COMPOSITION AND RESPONSIBILITIES OF THE MANAGEMENT COMMITTEE.

               (a)    From and after the date hereof, ITGE shall constitute a 
management committee of ITGE (the "Management Committee") consisting of all 
of the respective senior and mid-level managers and department heads of ITGE 
including, without limitation, the chief executive officer, chief operating 
officer, head of technology, head of operations, deputy chairman, head of 
sales trading and finance director of ITGE, and such other non-managerial 
members as the Management Committee may appoint from time to time to serve 



thereon.

               (b)    The Management Committee shall have the authority and 
responsibility to run the day-to-day operations of ITGE subject at all times 
to the direction and control of ITGE.  It is the intention of the Venturers 
that, in the event that ITGE in the future has more than one Subsidiary, 
there may be established more than one Management Committee or sub-committee 
so that authority and responsibility to run the day-to-day operations of each 
Subsidiary, or of groups of several Subsidiaries, may be appropriately 
delegated.

               (c)    The Management Committee shall not be operated in 
accordance with the general governance provisions contained in Article 9 and 
the Management Committee (and any such sub-committee thereof) will, when 
constituted, establish governance procedures; PROVIDED, HOWEVER, that such 
governance procedures shall follow the following guidelines:

                  (i) the members shall establish a regular weekly meeting 
schedule except that any non-managerial level member thereof will only be 
required to attend meetings on a monthly basis; and

                 (ii) the chief executive officer or, if such officer is not 
present at a meeting, the next most senior officer of the JV Companies in 
attendance shall act as chairman and preside over any such meetings.

       8.4     COMPOSITION AND RESPONSIBILITIES OF THE COMPENSATION AND AUDIT 
COMMITTEE.  The ITGL Board shall establish a Compensation Committee (the 
"Compensation Committee") and an Audit Committee (the "Audit Committee") each 
composed of two members who also serve on the ITGL Board, one of whom will be 
selected by the voting representatives serving on the Company Board that were 
designated by ITGI and the other of whom will be selected by the voting 
representatives serving on the Company Board that were designated by SG; 
PROVIDED, HOWEVER, that the members of the Audit Committee must not be 
Affiliates of either Venturer.

               The Compensation and Audit Committees shall have 




such authority as may be delegated to them from time to time by the ITGL 
Board with respect to compensation and financial matters, respectively.  

                                      ARTICLE 9
                               GOVERNANCE PROVISIONS

       9.1     MEETINGS; QUORUM; NOTICE. 

               (a)    The chairman (including any then acting alternating 
co-chairman) of each of the JV Boards shall prepare or direct the preparation 
of the agenda for, and preside over, meetings of the JV Board on which he 
serves as chairman.  The chairman shall deliver such agenda to each 
representative on the JV Board on which he serves as chairman at least two 
Business Days prior to giving of notice of a regular or special meeting and 
any representative on such JV Board may add items to such agenda.

               (b)    The Venturers anticipate that a regular meeting of each 
of the JV Boards shall be held at least once every six months.  The Company 
Board shall not meet in Ireland and any meetings of the ITGL or ITGE Board 
shall take place in Ireland.  Special meetings of any JV Board may be called 
by any voting representative on such JV Board and shall be held at such place 
as may be determined by such JV Board; PROVIDED, HOWEVER, special meetings of 
the Company Board shall not take place in Ireland and any special meetings of 
the ITGL or ITGE Board shall take place in Ireland.  Written notice of the 
time and place of each regular and special meeting of any JV Board shall be 
given by or at the direction of the chairman or co-chairman, as the case may 
be, of such JV Board to each representative on such JV Board, in the case of 
a regular meeting, at least ten Business Days, and in the case of a special 
meeting, at least two Business Days, before such meeting.  Whenever notice is 
required to be given to any representative on any JV Board, such notice shall 
specify the agenda for such meeting and, to the extent appropriate, shall be 
accompanied by supporting documentation.  The required notice to any 
representative may be waived by such representative in writing.  Attendance 
by a representative at a meeting shall constitute a waiver of any required 
notice of such meeting by such representative, except when such 
representative attends such meeting for the express purpose of objecting, at 
the beginning of the meeting, to the transaction of any 



business because the meeting is not properly called or convened.

               (c)    Except as expressly provided in this Agreement, the
presence of at least one voting representative designated by each of ITGI and SG
to serve on such JV Board shall be required to constitute a quorum for the
transaction of any business by any JV Board.  Each Party shall use its
reasonable efforts to ensure the existence of a quorum at any duly convened
meeting of any JV Board.  Except as expressly provided in this Agreement, no
action shall be taken by any JV Board with respect to any matter without the
affirmative vote of all of the voting representatives on such JV Board present
at a duly constituted meeting and no action shall be taken by the JV Boards with
respect to any matter without the affirmative vote of a majority of the voting
representatives of such Board present at a duly constituted meeting.  If fewer
than all of the voting representatives designated to such JV Board by a given
Venturer are present at a meeting, to the extent permitted by Applicable Law,
each representative or representatives of a Venturer present at such meeting
shall be entitled to vote the entire voting power held by all voting
representatives designated by such Venturer.  If more than one voting
representative appointed by a given Venturer is present at a meeting, to the
extent permitted by Applicable Law, such representatives shall vote such
Venturer's entire voting power in the same manner.

               (d)    While the Venturers intend that their representatives on
each of the JV Boards shall attend meetings of such JV Boards in person, the
Venturers acknowledge that representatives may from time to time be prevented
from doing so due to various circumstances.  Representatives on each JV Board
may, therefore to the extent permitted by Applicable Law, participate in a
meeting of such Board by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and participation in a meeting pursuant to this Section 9.1(d) shall
constitute presence in person at such meeting, except where a representative
participates in the meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business on the ground that
the meeting is not properly called or convened.

               (e)    To the extent permitted by Applicable Law, any action
required or permitted to be taken at a meeting of 




any JV Board may be taken without a meeting if a written consent, setting forth
the action so taken, is signed by all the voting representatives on such JV
Board and filed with the minutes of the proceedings of such Board.  Such consent
shall have the same force and effect as a unanimous affirmative vote of the
representatives on such JV Board.

       9.2     REMOVAL; RESIGNATION; VACANCIES.  A Venturer's designated
representatives on each JV Board shall hold office at the pleasure of such
Venturer which designated them.  Any such Venturer may at any time, by written
notice to the other Venturer and the applicable JV Board, remove (with or
without cause) its representative on such JV Board and designate a new
representative.  Subject to Applicable Law, no representative may be removed
except by the Venturer designating the same.  Any representative on any JV Board
may resign at any time by giving written notice to the Venturer which appointed
such representative and to such JV Board.  Such resignation shall take effect on
the date shown on or specified in such notice or, if such notice is not dated
and the date of resignation is not specified in such notice, on the date of the
receipt of such notice by the applicable JV Board.  No acceptance of such
resignation shall be necessary to make it effective.  Any vacancy on any JV
Board shall be filled only by the Venturer whose representative has caused the
vacancy, by giving written notice to such Body and to each other Venturer, and
each of the Venturers agree, as necessary, to vote, or to cause its designated
representatives on such JV Board to vote, for any Person so nominated by the
Venturer or other Person whose representative has caused such vacancy.

       9.3     NO REMUNERATION.   Unless the Venturers otherwise agree, no
person shall be entitled to any fee, remuneration or compensation in connection
with his service as a representative on or as a member of any JV Board. 
Notwithstanding the foregoing, the two non-executive, non-voting directors of
ITGL and ITGE who are residents of Ireland shall be paid an attendance fee of
Punt ,1,000 per meeting.

                                   INDEMNIFICATION

       10.1     INDEMNIFICATION.




               (a)    To the fullest extent permitted under Applicable Law, the
JV Companies shall indemnify and hold harmless, or cause its Subsidiaries to
indemnify and hold harmless, each of their respective Affiliates and all
officers, directors and shareholders (including the Venturers) of such
Affiliates, and each director and officer of any JV Company and any Person
serving in any similar capacity for another Person (including any JV Board)
affiliated with the JV Companies at the request of the Company or any of its
Subsidiaries (solely for purposes of this Section 10.1, each of the foregoing
Persons being referred to as, a "Company Affiliate"), from and against any and
all losses, claims, demands, costs, damages, liabilities, expenses of any nature
(including reasonable attorneys' fees and disbursements), judgments, fines,
settlements and other amounts arising from any and all claims, demands, actions,
suits or proceedings, whether civil, criminal, administrative or investigative,
in which a Company Affiliate may be involved, or threatened to be involved, as a
party or otherwise, arising out of or incidental to the business of the Joint
Venture, regardless of whether a Company Affiliate continues to be a Company
Affiliate, at the time any such liability or expense is paid or incurred, if (i)
the Company Affiliate acted in good faith and in a manner it or he reasonably
believed to be in, or not opposed to, the interests of the JV Companies and,
with respect to any criminal proceeding, had no reason to believe its or his
conduct was unlawful, and (ii) the Company Affiliate's conduct did not
constitute actual fraud, gross negligence or willful or wanton misconduct.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of NOLO CONTENDERE, or its equivalent, shall not, in
and of itself, create a presumption or otherwise constitute evidence that the
Company Affiliate acted in a manner contrary to that specified in (i) or (ii)
above.

               (b)    Expenses (including reasonable legal fees and expenses)
incurred in defending any proceeding subject to subsection (a) of this Section
10.1 shall be paid by the JV Companies in advance of the final disposition of
such proceeding upon receipt of a written affirmation by the Company Affiliate
of his or its good faith belief that he or it has met the standard of conduct
necessary for indemnification under this Section 10.1 and a written undertaking
(which need not be secured) by or on behalf of the Company Affiliate to repay
such amount if it shall ultimately be determined, by a court of competent 




jurisdiction or otherwise, that the Company Affiliate is not entitled to be
indemnified by the Company as authorized hereunder.

               (c)    The indemnification provided by this Section 10.1 shall
be in addition to any other rights to which each Company Affiliate may be
entitled under any agreement or vote of a JV Board by the vote of
representatives that are disinterested and unaffiliated with such Company
Affiliate, as a matter of law or otherwise, both as to action in the Company
Affiliate's capacity as a Company Affiliate or as a Person serving at the
request of a JV Company and shall continue as to a Company Affiliate who has
ceased to serve in such capacity and shall inure to the benefit of the heirs,
successors, assigns, administrators and personal representatives of such Company
Affiliate.

               (d)    The JV Companies shall purchase and maintain directors
and officers insurance or, similar coverage, for its directors and its officers
in such amounts and with such deductibles or self-insured retentions as are
customary for Persons engaged in businesses similar in size and type to those
engaged in by the Joint Venture. 

               (e)    Any indemnification hereunder shall be satisfied only out
of the assets of the JV Companies and the Venturers shall not be subject to
personal liability by reason of these indemnification provisions.  

               (f)    A Company Affiliate shall not be denied indemnification
in whole or in part under this Section 10.1 because the Company Affiliate had an
interest in the transaction with respect to which the indemnification applies if
the transaction was otherwise permitted by the terms of this Agreement and all
material facts relating to such Company Affiliate's interest were adequately
disclosed to the appropriate JV Board at the time the transaction was
consummated.

               (g)    The provisions of this Section 10.1 are for the benefit
of the Company Affiliates and the heirs, successors, assigns, administrators and
personal representatives of the Company Affiliates and shall not be deemed to
create any rights for the benefit of any other Persons.

               (h)    Any repeal or amendment of any provisions of this Section
10.1 shall be prospective only and shall not 




adversely affect any Company Affiliate's right existing at the time of such
repeal or amendment. 


                                      ARTICLE 11
                                      DEADLOCKS

       11.1    DEADLOCKS.
       
               (a)    The parties agree that all Deadlocks on the Company
Board, the ITGL Board or the ITGE Board shall be resolved in accordance with
this Article 11.

               (b)    A deadlock (a "Deadlock") shall be deemed to have
occurred upon the failure of the Company Board, the ITGL Board or the ITGE
Board, as the case may be, to reach a decision with respect to any of the
following matters after a vote has been taken by the requisite voting
representatives on the Company Board, the ITGL Board or the ITGE Board, as the
case may be,:

                  (i) approval of any annual budget;

                 (ii) approval of a Capital Call in excess of the Stop Loss;

                (iii) approval of financings (debt or equity);

                 (iv) approval of any acquisition or disposition in excess of
                      GB,1,000,000;

                  (v) approval of any material change in the purpose and
                      strategic direction of the JV Business from that set 
                      forth in the Business Plan; or

                 (vi) decisions relating to the hiring, firing or compensation
                      of the chief executive officer of the Company.

               (c)    If a Deadlock occurs on the Company Board, the ITGL Board
or the ITGE Board, as the case may be, any voting representative on the Company
Board, the ITGL Board or the ITGE Board, as the case may be, within twenty (20)
days of the vote which give rise to such Deadlock, by written notice to the
other voting representatives on such board, and to the Founders Committee, refer
the Deadlock for




resolution pursuant to Section 11.1(d).  If no such voting representative 
refers such Deadlock to the Founders Committee for resolution within such 
20-day period, no further action shall be taken by the Company Board, the 
ITGL Board or the ITGE Board, as the case may be, with respect to the 
proposal which gave rise to such Deadlock, but such proposal may be presented 
at a subsequent meeting of such board and any resulting Deadlock shall again 
be resolved in accordance with this Section 11.1(c).  

               (d)    If a Deadlock is referred to the Founders Committee for 
resolution, the Founders Committee shall have thirty (30) days to consider 
and attempt to resolve such Deadlock. If the Deadlock cannot be resolved by 
the Founders Committee within such 30-day period, the Founders Committee 
shall designate either (i) any voting representative serving on the Company 
Board, the ITGL Board or the ITGE Board, as the case may be, that is not an 
Affiliate of either Venturer or (ii) another person that is not an Affiliate 
of either Venturer and is qualified to act as an arbitrator with respect to 
the particular proposal that is the subject of the Deadlock (such 
representative or other person being herein referred to as, the "Third Party 
Arbitrator").  Such Third Party Arbitrator shall arbitrate the subject of the 
Deadlock in accordance with the rules of the International Chamber of 
Commerce (the "ICC") in effect on the date hereof and shall have thirty (30) 
days from his designation to recommend a course of action with respect to 
such Deadlock by sending written notices setting forth such course of action 
to the Company Board, the ITGL Board or the ITGE Board, as the case may be, 
and the Venturers (the "Resolution").  Unless during the 10-Business Day 
period following receipt of such notice the Venturers mutually agree upon a 
different course of action than the Resolution (in which event such different 
course of action shall for purposes of this Agreement be referred to as the 
"Venturer Resolution"), the Resolution or the Venturer Resolution, as the 
case may be, shall be final and binding on the Parties and the Venturers 
shall cause their voting representatives on the Company Board, the ITGL Board 
or the ITGE Board, as the case may be, to take action accordingly.

               (e)    If there has been no Venturer Resolution and ITGI has 
not delivered a notice to SG pursuant to Section 11.1(f), following receipt 
of the notice of Resolution pursuant to Section 11.1(d), SG shall have the 
right at any time within a period of thirty (30) days from receipt thereof, 
by written notice to ITGI, to require ITGI



to purchase all, but not less than all, of its Venture Interest for a cash 
price equal to one hundred-fifty percent (150%) of the applicable Reference 
Value.  Such right shall be exercised by delivery of a written notice by SG 
to ITGI within such 30-day period.  The date of such notice is referred to 
herein as the "Resolution Put Notice Date".  Promptly following the 
Resolution Put Notice Date, the Venturers shall commence determining the 
Reference Value as set forth on SCHEDULE 1.1.

               (f)    If there has been no Venturer Resolution and SG has not 
delivered a notice to ITGI pursuant to Section 11.1(e), following receipt of 
the notice of Resolution pursuant to Section 11.1(d), ITGI shall have the 
right at any time within a period of thirty (30) days commencing from the 
receipt thereof, by written notice to SG, to require SG to sell all, but not 
less than all, of its Venture Interest for a cash price equal to one 
hundred-fifty percent (150%) of the applicable Reference Value. Such right 
shall be exercised by delivery of a written notice by ITGI to SG within such 
30-day period.  The date of such notice is referred to herein as the 
"Resolution Call Notice Date." Promptly following the Resolution Call Notice 
Date, the Venturers shall commence determining the Reference Value as set 
forth on SCHEDULE 1.1.

               (g)    The closing of a purchase and sale pursuant to Section 
11.1(e) or 11.1(f) shall occur in accordance with Sections 12.5 and 12.6.

                            TRANSFERS OF VENTURE INTERESTS

       12.1    GENERAL RESTRICTIONS.  No Venturer may Transfer all or any 
part of such Venturer's Venture Interest, except as provided in this 
Agreement.  Any purported Transfer of a Venturer's Venture Interest or a 
portion thereof in violation of the terms of this Agreement shall be null and 
void and of no effect.  Any permitted transferee desiring to make a further 
Transfer shall become subject to all the provisions of this Article 12 to the 
same extent and in the same manner as any Venturer desiring to make any 
Transfer.  

       12.2    PERMITTED TRANSFEREES.  Notwithstanding the provisions of 
Sections 12.3 and 12.4, each Venturer shall have the right to Transfer, by a 
written instrument, all or any part of its Venture Interest to a Permitted 
Affiliate;




PROVIDED, HOWEVER, that such transfer is not materially financially 
detrimental to the JV Companies and that such Permitted Affiliate shall 
execute an instrument in form and substance reasonably satisfactory to the 
Company Board accepting and adopting the terms and provisions of this 
Agreement and the other Operative Agreements to which the transferor is a 
party and shall pay all reasonable expenses of the Company in connection with 
such Transfer, it being understood that upon such Transfer the transferor 
shall remain obligated under the Operative Agreements unless the Company 
Board otherwise agrees.

       12.3    RIGHT OF FIRST REFUSAL.  

               (a)  If any Venturer (the "Seller") desires to Transfer all, 
and not less than all, of its Venture Interest (the "Offered Interest") 
pursuant to a bona fide offer (the "Bona Fide Offer") from a third party (the 
"Proposed Transferee"), other than a transferee permitted by Section 12.2, it 
shall submit a written offer (the "Written Offer") to Transfer such Venture 
Interest (collectively, the "Offered Interest") to the other Venturer (the 
"Offeree") on terms and conditions, including price, not less favorable to 
the Offeree than those on which the Seller proposes to Transfer such Offered 
Interest to the Proposed Transferee.  The Written Offer shall disclose the 
identity of the Proposed Transferee, the Person or Persons, if any, that 
Control such Proposed Transferee, the Offered Interest proposed to be 
Transferred, the total number of Ordinary Shares and principal amount of any 
Subordinated Debt owned by the Seller, the terms and conditions, including 
price, of the proposed Transfer, and any other material facts relating to the 
proposed Transfer.  The Written Offer shall further state that the Offeree 
may acquire, in accordance with the provisions of this Agreement, all of the 
Offered Interest for the price and upon the other terms and conditions, 
including deferred payment (if applicable), set forth therein. 

               (b)    The Offeree shall be permitted to confirm that the Bona 
Fide Offer is firm and subject only to conditions that could reasonably be 
expected to be satisfied, by (i) review of the documents involved in such 
Bona Fide Offer and (ii) requiring that the Proposed Transferee submit 
evidence reasonably satisfactory to the Offeree of any financing for such 
purchase.  

               (c)    (i)     If the Offeree elects to purchase the 




Offered Interest at the price offered by the Proposed Transferee, the Offeree 
shall communicate in writing its election to purchase to the Seller, which 
communication shall be delivered to the Seller within 30 days of the date the 
Written Offer was made.  Such communication shall, when taken in conjunction 
with the Written Offer, be deemed to constitute a valid, legally binding and 
enforceable agreement for the sale and purchase of the Offered Interest.  

                      (ii)    The closing of the sale and purchase of the 
Offered Interest to the Offeree shall occur in accordance with Sections 12.5 
and 12.6.

                      (iii)   If the Offeree does not elect to so purchase 
the Offered Interest, the Seller may sell the entire Offered Interest to the 
Proposed Transferee within 90 days following the expiration of the thirty 
(30) day period referred to in Section 12.3(c), upon terms that are no more 
favorable to the Proposed Transferee than those set forth in the Written 
Offer.  For purposes of the preceding sentence, a purchase price that is less 
than ninety-five percent (95%) of the purchase price set forth in the Written 
Offer will be deemed more favorable to the Proposed Transferee.  If the 
Proposed Transferee does not carry out its purchase within said 90-day 
period, or else withdraws its offer or introduces any changes thereto, the 
Offered Interests may not be sold, assigned or transferred unless previously 
offered to the Venturers once again pursuant to this Section 12.3. 

       12.4    VENTURER CHANGE OF CONTROL

               (a)    SG shall have the right at any time within sixty (60) 
days after the later of (i) the occurrence of a Venturer Change of Control or 
(ii) the giving of notice of such Venturer Change of Control pursuant to 
Section 6.4, by written notice to ITGI (the date of such notice is referred 
to herein as the "Control Put Notice Date"), to require ITGI to purchase all, 
but not less than all, of its Venture Interest for a cash price equal to the 
Reference Value. Promptly following the Control Put Notice Date, the 
Venturers shall commence determining the Reference Value as set forth on 
SCHEDULE 1.1.

               (b)    ITGI shall have the right at any time within sixty (60) 
days after the later of (i) the occurrence of a Venturer Change of Control or 
(ii) the giving of notice




of a Venturer Change of Control pursuant to Section 6.4, by written notice to 
SG (the date of such notice is referred to herein as the "Control Call Notice 
Date"), to require SG to sell all, but not less than all, of its Venture 
Interest for a cash price equal to the applicable Reference Value.  Promptly 
following the Control Call Notice Date, the Venturers shall commence 
determining the Reference Value as set forth on SCHEDULE 1.1.

               (c)    The closing of a purchase and sale pursuant to Section 
12.4(a) or 12.4(b) shall occur in accordance with Sections 12.5 and 12.6.

       12.5    GOVERNMENTAL APPROVALS.  Each of the Parties shall use all 
reasonable commercial efforts to obtain all Governmental Approvals required 
to effect any purchase and sale of Venture Interests pursuant to Sections 
11.1(e), 11.1(f), 12.3(c)(ii), 12.4(a) or 12.4(b).  If the required 
Governmental Approvals have not been received at the time any such closing is 
scheduled to occur, the contemplated transfer shall be deferred and made 
conditional until such time as the required Governmental Approvals have been 
obtained.

       12.6    CLOSING OF PURCHASE OF VENTURE INTERESTS.  Unless the 
Venturers otherwise agree, the closing of any purchase and sale of Venture 
Interests pursuant to Sections 11.1(e), 11.1(f), 12.3(c)(ii), 12.4(a) or 
12.4(b) shall occur at the Company's principal executive office within sixty 
(60) days after the applicable notice of purchase and sale has been 
furnished.  At such closing, (i) the Venturer transferring such Venture 
Interests (the "Transferring Party") shall transfer, assign and deliver to 
the Person purchasing such Venture Interests (the "Non-Transferring Party") 
the certificates or other documents evidencing the Venture Interests being 
purchased, duly endorsed for transfer, together with such assignments 
separate from any such certificate and other documents or instruments 
reasonably required by counsel for the Non-Transferring Party to consummate 
such purchase, and (ii) the Non-Transferring Party shall pay the purchase 
price in cash in GB Pounds Sterling.  In addition, at the closing of such 
purchase and sale, (A) the Transferring Party shall deliver to the 
Non-Transferring Party an executed, written representation, in form and 
substance reasonably satisfactory to legal counsel for the Non-Transferring 
party, that the Transferring Party owns the Venture Interests free and clear 
of all Security Interests and that upon the delivery of the Venture 




Interests, the Transferring Party shall have transferred all of its right, 
title and interest in the Venture Interests, and (B) the Non-Transferring 
Party shall deliver to the Transferring party such investment representations 
as may be reasonably required to comply with applicable securities laws.

                         OTHER ACTIVITIES BY THE VENTURERS; 
                       EXPANSION OF TERRITORY; CONFIDENTIALITY

       14.1    IN GENERAL.  The Venturers acknowledge that to support their 
intention to make the Joint Venture the principal embodiment of the JV 
Business of the Venturers and to protect adequately their interests in the JV 
Companies, it is necessary and essential that the Venturers enter into and

               (a)    From and after the date hereof and until a date twelve

                      serve as senior officer or member of a board of 
                      directors, managing board or similar governing body of 
                      a Major Competitor of the JV Companies.

               (b)    In the event that the ITGI License Agreement is 
terminated by ITGI in accordance with Section 8(a)(iv) of the ITGI License 
Agreement, the non-compete obligations set forth in Section 14.2(a) above 
shall cease to apply.

       14.3    NON-COMPETITION EXCEPTIONS.  Except as expressly set forth in 
this Section 14.3, nothing in this Article 14 shall be construed to prohibit 
any of the following activities by a Venturer or any of its Affiliates after 
the date hereof.

               (a)    INVESTMENTS.  The acquisition or ownership by a 
Venturer (directly or indirectly through an Affiliate) (other than where such 
acquisition or ownership is held by such Venturer solely as a trustee or 
nominee for an unaffiliated third party) of a Person or an Equity Interest in 
such a Person through merger, consolidation, purchase of stock or assets or 
otherwise, if the annual consolidated gross revenues attributable to 
Competing Services of such Person do not exceed five percent (5%) of the 
annual consolidated gross revenues of such Person as set forth in the most 
recently available audited financial statements of such Person as of the date 
of execution of the definitive agreement providing for such acquisition.

               (b)    FIVE PERCENT INVESTMENTS.  The acquisition or ownership 
by a Venturer (directly or indirectly through an Affiliate) of any securities 
of a publicly held Person engaged in Competing Services, if such securities 
(i) were not acquired directly from such Person in a private placement or 
similar transaction, (ii) do not represent more than five percent (5%) of the 
aggregate voting power of the outstanding equity securities of such Person 
(other than where such acquisition or ownership is held by such Venturer 
solely as a trustee or nominee for an unaffiliated third




party) (assuming the conversion, exercise or exchange of all such securities 
held by such Venturer or its Affiliate that are convertible, exercisable or 
exchangeable into or for voting securities), and (iii) in the case of debt 
securities, entitle the holder thereof to receive only interest or other 
returns that are not based on the value or results of operations of such 
Person.

               (c)    INVESTMENT FUNDS.  The acquisition or ownership 
(directly or indirectly thorough an Affiliate) by a Venturer of an ownership 
interest in an investment fund or plan (including pension and retirement 
plans) investing on behalf of the employees or retirees of such Venturer or 
its Affiliates or the continued sponsorship by such Venturer (or Affiliate) 
thereof; provided that no investment by any such fund or plan has the purpose 
or effect of changing or influencing the Control of any Person that Offers 
Competing Services.

       14.4    EXPANSION OF TERRITORY.  Each of the Venturers acknowledges 
that the JV Business shall only be conducted in connection with equity 
securities traded on securities exchanges located within the Territory and 
that the countries and regions comprising the Territory can only be changed 
by mutual agreement in writing by the Venturers.  The foregoing 
notwithstanding, in the event any Venturer contemplates Offering Competing 
Services in any country or region in South Africa, Turkey or Asia that is not 
part of an Excluded Territory, such Venturer shall first consult with the 
other Venturer with respect to expanding the Territory to include such 
country or region.

       14.5    CONFIDENTIALITY.  Each Venturer shall use, and shall cause its 
Affiliates, employees and agents to use, their respective reasonable best 
efforts to ensure that the terms of this Agreement, the other Operative 
Agreements (including all Exhibits and Schedules hereto and thereto) and 
confidential proprietary information concerning the other Venturer, the JV 
Business and affairs of the Company and its Subsidiaries are not disclosed to 
third parties unless the other Venturer shall have consented to such 
disclosure in writing; PROVIDED, HOWEVER, that such information may be 
disclosed to third parties to the extent reasonably required to accomplish 
any proposed transfer under Article 12, as necessary in connection with any 
private offering of securities of a Venturer or any of its Affiliates, if the 
Person to which the information is disclosed agrees in writing to keep such 
information 




confidential, as necessary in connection with any Public Offering of 
securities of a Venturer or any of its Affiliates (and related reporting 
obligations occasioned thereby), and as required by law.

                                      ARTICLE 15
                             TERM AND TERMINATION DEFAULT

       15.1    TERM OF JV COMPANIES.  Each JV Company shall continue without 
interruption until it is dissolved and terminated pursuant to the terms of 
this Agreement, the Constituent Documents and Applicable Law.

       15.2    TERMINATION OF JOINT VENTURE.  The following shall be 
"Termination Conditions" with respects to the Joint Venture:

               (a)    a Funding Breach with respect to a Capital Call (in 
which case the non-defaulting Venturer may deliver a written notice (a) 
"Termination Notice") in accordance with Section 15.3;

               (b)    a Material Non-Monetary Default (in which case the 
non-defaulting Venturer may deliver a Termination Notice in accordance with 
Section 15.3);

               (c)    the Bankruptcy of a Venturer (in which case the 
non-bankrupt Venturer may deliver a Termination Notice in accordance with 
Section 15.3);

               (d)    the termination of the POSIT License (in which case any 
Venturer may deliver a Termination Notice in accordance with Section 15.3); or
               
               (e)    written mutual consent of the Venturers (in which case 
any Venturer may deliver a Termination Notice in accordance with Section 
15.3).

       15.3    TERMINATION NOTICE. 

               (a)    If a Termination Condition occurs, a Party entitled to 
deliver a Termination Notice pursuant to Section 15.2 may give such 
Termination Notice to the other Parties and to the Executive Committee within 
60 days following the date upon which such Party becomes aware of the 
occurrence of the Termination Condition.  If any Venturer delivers a 
Termination Notice, the other Venturer shall be precluded 




from delivering a subsequent Termination Notice.

               (b)    Each Venturer acknowledges and agrees that (i) it shall 
not challenge the validity of any provision of this Article 15 in any 
Proceeding and (ii) each Venturer shall have a right to seek specific 
performance of each provision of this Article 15.

       15.4    TERMINATION UPON DEFAULT, ETC.  In the case of a Termination 
Condition under Section 15.2(a), (b) or (c), the non-defaulting Venturer 
delivering the Termination Notice shall have the right to exercise its option 
to purchase all but not less than all, of the Venture Interest of the 
defaulting Venturer at eighty percent (80%) of the defaulting Venturer's 
investment to date plus interest on amounts invested from time to time at the 
Applicable Rate (the "Default Termination Value") by delivering a written 
notice of exercise within sixty (60) days following the occurrence of any 
such Termination Condition. This reduction to eighty percent (80%) of the 
investment to date plus interest on amounts invested from time to time at the 
Applicable Rate is agreed by both parties as a reasonable pre-estimate by way 
of liquidated damages of the likely loss, direct and indirect, which would be 
incurred by the non-defaulting Venturer in consequence of a Termination 
Condition arising under Section 15.2 (a) (b) or (c) hereof in relation to the 
defaulting Venturer, this assessment taking into account the financial and 
other commitments made by both Venturers under this Agreement in relation to 
the establishment and proposed long term operation of the Joint Venture.  
Such written notice shall constitute an offer by the non-defaulting Venturer 
to purchase the Venture Interests of the defaulting Venturer at a price equal 
to the Default Termination Value, and the defaulting Venturer hereby accepts 
any such offer by the non-defaulting Venturer.  If the non-defaulting 
Venturer fails to deliver such written notice of such exercise within said 
60-day period, it will be deemed to have elected not to purchase the Venture 
Interest of the defaulting Venturer.  In the event that non-defaulting 
Venturers purchases the Venture Interest of the defaulting Venturers pursuant 
to this Section 15.4, the purchase price for the Venture Interest shall be an 
amount payable in cash in GB Pounds Sterling.

       15.5    CLOSING.  Each of the Parties shall use its reasonable efforts 
to obtain all Governmental Approvals required to effect the purchase and sale 
of Venture Interests, pursuant to Section 15.4.  Unless the Parties 




have failed to receive all required Governmental Approvals, the closing of 
the purchase of a Venture Interest pursuant to this Article 15 shall be held 
at the offices of the purchasing Venturer within ten (10) days after the 
final determination of the purchase price to be paid to the selling Venturer. 
 If in spite of the Venturers' efforts in this regard, the required 
Governmental Approvals have not been received at the time the closing is 
scheduled to occur, the closing shall be postponed until such date as the 
Venturers shall have obtained the required Governmental Approvals; provided 
that, if such Governmental Approvals are not obtained prior to the first 
anniversary of the date on which such closing is postponed, at the request of 
any Venturer, the Venturers shall negotiate in good faith to provide for the 
termination of the Joint Venture pursuant to such mutually agreeable terms 
and conditions as will permit the Venturers to obtain all Governmental 
Approvals required for the termination of the Joint Venture, and as will have 
substantially the same economic consequences to the Venturers as the 
transaction contemplated by Section 15.4.  At the closing, the purchasing 
Venturer and the selling Venturer shall make the deliveries specified in 
Section 12.6.

       15.6    TERMINATION BY DISSOLUTION. In the case of a Termination 
Condition under Section 15.2(d) or (e) upon delivery of a Termination Notice, 
the Venturers shall proceed to dissolve the Joint Venture by the Venturers 
causing their representatives on the JV Boards to proceed with the winding up 
of the affairs and liquidation of the JV Companies through the sale of their 
respective assets and properties.  Notwithstanding the foregoing, in the 
event that a Venturer fails to give a Termination Notice within the time 
period set forth in Section 15.3, such Venturer shall be deemed to have 
waived its right to dissolve, with respect to the event or events which gave 
rise to such right to dissolve.




                                      ARTICLE 16
                             POST TERMINATION PROVISIONS

       16.1    CONSEQUENCES OF TERMINATION.  Upon the transfer by at least 
one Venturer of its entire Venture Interest in accordance with this Agreement 
(other than a transfer pursuant to Section 12.2), this Agreement and the 
other Operative Agreements shall forthwith cease to have effect as between 
such Party and the other Parties, and all further obligations of such Party 
(and its Affiliates) to such other Parties (and their Affiliates) and of such 
other Parties (and their Affiliates) to such Party (and its Affiliates) shall 
terminate with this Agreement and the other Operative Agreements without 
further liability, except that:

               (a)    such transfer shall not constitute a waiver of any 
rights that any Party (or any of its Affiliates) may have by reason of a 
breach of this Agreement or any other Operative Agreement, subject to any 
limitations thereon in this Agreement or the other Operative Agreements;

               (b)    the provisions of this Article 16, Article 10, Article 
14, other than Section 14.4, and Article 18, other than Sections 18.8 and 
18.10 of this Agreement shall continue in full force and effect; and

               (c)    The rights and obligations of the Parties (and their 
Affiliates) under the Service Agreements shall continue in full force and 
effect for a period of six months from such transfer; and

               (d)    the rights and obligations of the Parties (and their 
Affiliates) under the Operative Agreements, other than the Service 
Agreements, shall continue in full force and effect to the extent provided in 
the Transition Plan.

       16.2    NON-SOLICITATION.  Anything herein to the contrary 
notwithstanding, upon the Transfer by SG of all of its Venture Interest in 
accordance with this Agreement, for a period commencing on the date of such 
Transfer and ending on the first anniversary of such Transfer, SG shall not, 
and shall cause its Affiliates not to, induce or attempt to influence any 
employees of the JV Companies or any of their Affiliates to terminate such 
employee's employment therewith.

       16.3    TRANSITION PLAN.  The Parties agree to negotiate 




in good faith to develop a plan (the "Transition Plan") which will govern the 
rights and obligations of the parties under the Operative Agreements 
following an event described in Section 16.1 and which will ensure that the 
successor to the JV Business shall continue to supply services to its 
customers without disruption. Each of the Parties agrees to cause its 
Affiliates and, insofar as within its control, the JV Companies, to comply 
with the provisions of the Transition Plan.

                                      ARTICLE 17
                NEGOTIATIONS; ARBITRATION; SUBMISSION TO JURISDICTION

       17.1    NEGOTIATIONS; ARBITRATION.  (a)  In the event of any dispute, 
controversy or claim (other than a Deadlock) arising out of or relating to 
this Agreement, or the performance, breach, termination, or invalidity 
hereof, such dispute, controversy or claim shall be the subject of an attempt 
at an amicable solution, for which purpose any party shall give notice to the 
other parties, giving a concise description of the matter in question and the 
position of such party in respect thereof and proposing a meeting among the 
chief executive officers, executive managing directors or their designees 
(the "Senior Officers") of the ultimate parent companies of the Venturers in 
The City of Dublin (or such other place as they may agree) with the purpose 
of resolving the dispute, controversy or claim.

               (b)    In the event such a meeting is called, the meeting 
shall take place within ten (10) Business Days of its being requested.  
Unless the parties otherwise agree, if such meeting does not take place 
within such ten (10) Business Days or if within ten (10) Business Days after 
such meeting the Senior Officers have not resolved such matter, then the 
matter shall be settled by arbitration in accordance with the rules of the 
ICC in effect on the date hereof.  The arbitration shall be the sole and 
exclusive forum for resolution of the dispute, controversy or claim, and the 
award shall be final and binding. Judgment thereon may be entered by any 
court having jurisdiction.  The number of arbitrators shall be three (or such 
other number as shall be stipulated by the most recent then existing Rules of 
the ICC), each of whom shall be disinterested in the dispute, controversy or 
claim and shall be impartial and independent of any party.  Each Venturer 
(and its Affiliates, as applicable) and Venturer (and its Affiliates, as 
applicable) shall appoint one arbitrator, and the two so appointed shall 




choose a third arbitrator.  If the arbitrators chosen by the Venturers cannot 
agree on the choice of the third arbitrator within a period of thirty (30) 
days after both of them have been appointed, then the third arbitrator shall 
be appointed by the ICC.  The parties and the appointing authority may 
appoint from among the nationals of any country, whether or not a party is a 
national of that country.  The place of arbitration shall be The City of 
Dublin, Ireland.  The arbitration shall be conducted in the English language 
and any foreign-language documents presented at such arbitration shall be 
accompanied by an English translation thereof.  The arbitrators shall state 
the reasons upon which the award is based.  The arbitrators shall apply the 
laws of Ireland without regard to the principles of conflicts of laws.

               (c)    Any matter expressed in this Agreement to be a matter 
for review, collaboration, consultation, consent, decision, agreement or vote 
by the parties or any of them shall not, in the event of failure of decision 
or agreement, constitute a dispute or difference to be referred to or settled 
by arbitration proceedings.

               (d)    Each of the parties hereby submits to the exclusive 
jurisdiction of the Irish Courts (the "Specified Court") in any action, suit 
or proceeding with respect to the enforcement of the arbitration provisions 
of this Agreement and the non-exclusive jurisdiction of such court with 
respect to the enforcement of any award thereunder.  Each party irrevocably 
appoints the agent for service specified opposite its name on the signature 
pages hereof as its authorized agent in the city of Dublin, Ireland upon 
which process may be served in any related proceeding, and agrees that 
service of process upon such agent, and written notice of said service to 
such party, by the person serving the same to the address so provided, shall 
be deemed in every respect effective service of process upon such party in 
any such action, suit or proceeding.  Each party further agrees to take any 
and all action as may be necessary to maintain such designation and 
appointment of such agent in full force and effect for the duration of this 
Agreement.

any obligation of any kind, express or implied, against or in the name or on
behalf of any other Party or any of its Affiliates or the Joint Venture or any
of the JV Companies unless otherwise expressly permitted by such Party.

       18.13   RELATIONSHIP OF THE PARTIES.  The relationship among the Parties
shall not be that of partners and nothing herein contained shall be deemed to
constitute a partnership among them.

       18.14   FIDUCIARY DUTIES.  Subject to Applicable Law, no Party or any of
its Affiliates nor any officer, director, employee or former employee of any
Party or its Affiliate shall have any obligation, or be liable, to any Party,
the Joint Venture or any JV Company for exercising any of the rights of such
Party or such Affiliate under this Agreement or any other Operative Agreement to
which it is or will be a party, for exercising or failing to exercise its rights
as a shareholder of any JV Company or for breach of any fiduciary or other
similar duty to any Party, the Joint Venture or any JV Company by reason of such
conduct, other than a breach of any Operative Agreement.

       IN WITNESS WHEREOF, each of the Parties has cause its respective duly 
authorized officers to execute this


Agreement as of the day and year first above written.

                                    November 17, 1998


             GUARANTEE BY INVESTMENT TECHNOLOGY GROUP, INC.


     To Societe Generale, Investment Technology Group SG Limited, Investment 
Technology Group Limited and Investment Technology Group Europe Limited 
(collectively, the "Guaranteed Parties")

1.   In consideration of the Guaranteed Parties entering into a Joint Venture 
     Agreement (the "Agreement") by and among the Guaranteed Parties and ITG 
     International Limited ("ITGI"), dated as of November 17, 1998, 
     Investment Technology Group, Inc. ("Guarantor"), the corporate parent of 
     ITGI, unconditionally and irrevocably, as a primary and continuing 
     obligation, guarantees to the Guaranteed Parties, the proper and 
     punctual performance by ITGI of all of ITGI's obligations under the 
     Agreement and undertakes to pay on demand, all amounts whatsoever owing 
     by ITGI under the Agreement.

2.   This guarantee is a continuing guarantee and will remain in force until 
     all the obligations (actual or contingent) of ITGI under the Agreement 
     have been discharged in full.

3.   The Guarantor shall not, without first obtaining the Guaranteed Parties' 
     written consent, act in a liquidation or winding up of ITGI in 
     competition with the Guaranteed Parties for any amount whatsoever owing 
     by ITGI pursuant to the Agreement.

4.   All amounts payable hereunder shall be paid in full without any 
     deduction or withholding whatsoever (whether in respect of set-off, 
     counterclaim, duties, taxes or charges) unless such deduction or 
     withholding is required by law, in which event the Guarantor shall pay 
     under the Agreement an additional amount so that the net amount received 
     by the Guaranteed Parties will equal the full amount which the 
     Guaranteed Parties would have received had such amount been paid 
     directly by ITGI.

5.   The Guarantor acknowledges that it has represented to


     the Guaranteed Parties and hereby warrants, that it has full power and 
     authority to enter into this Guarantee, that it has taken all necessary 
     corporate or other actions to authorize the same, and that as executed, 
     this Guarantee (and the performance of all its obligations herein 
     contained) does not and will not constitute a breach of any law or 
     governmental regulation or order to which the Guarantor is subject, or 
     any agreement by which the Guarantor is bound, and is and will be valid, 
     binding and enforceable in accordance with its terms.

6.   Terms defined in the Agreement shall bear the same meanings when used 
     herein.

7.   Any notice or demand herein shall be in writing in the English language 
     and shall be delivered by hand or courier service, mailed or sent by 
     facsimile, as follows:

     Guarantor shall advise the Guaranteed Parties in writing.  All notices 
     and demands given or served in accordance with the provisions of this 
     Guarantee shall be deemed to have been given on the date of receipt.  
     Communications sent by facsimile shall be deemed to have been received 
     when confirmation of delivery is received by the sender.

8.   The validity, construction and performance of this Guarantee shall be 
     governed by and construed in accordance with the laws of Ireland 
     regardless of the laws that might otherwise govern under applicable 
     principles of conflicts or choice of law.
