                             Joint Venture Agreement

                              (Umbrella Agreement)

between

Seat Pagine Gialle SpA, with domicile in Turin (hereinafter "Seat"), an Italian
stock corporation,

and

RSL COM Deutschland GmbH, with domicile in Frankfurt am Main, a German limited
liability company (hereinafter "RSL"),

(hereinafter together the "Parties")

                                    Preamble

Seat is mainly active in the fields of producing and publishing telephone
directories and similar publications, and of selling advertising space in such
directories and publications, as well as providing direct marketing services, in
Italy and elsewhere.

RSL is active in the field of providing a broad range of voice, data, internet
and value-added product and service solutions within the telecommunications
industry.

RSL is active in the said field through amongst others (since 1998) a
participation of approx. 50.2 % in Telegate Holding GmbH (hereinafter the
"Holding"), a German holding company which in turn holds approx. 51% of the
shares in Telegate AG (hereinafter "Telegate"), a German stock corporation whose
shares are traded on the Frankfurt Neuer Markt and which is also active in the
field of providing directory assistance and other information, mostly via
telephone but also through an internet portal. Concurrently with the
notarization of this Agreement, Seat will notarize an agreement with the sole
other shareholder in the Holding, L, (the "L Umbrella Agreement") with a view to
acquire L's shareholding in the Holding.

<PAGE>

RSL wishes to expand the existing cooperation between RSL and Telegate currently
consisting of providing call completion services domestically and
internationally into a strategic partnership with Seat, as the new joint
venture-partner, by means of entering into a joint venture with Seat through
joint shareholding in the Holding (as a consequence of L's exit), allowing Seat
to take the lead in the joint venture and restricting RSL's role therein to
support Seat; it is anticipated that the support by RSL will no longer be needed
after a certain period of time. In view of that later time RSL wishes to offer
Seat and Seat wishes to offer RSL the right to request Seat to acquire RSL's
remaining shareholding in the Holding.

RSL wishes to allow Seat to take the lead in the Holding, and thus wishes to
transfer to Seat a 1.6 % share in the Holding thereby conferring the majority of
the Holding to Seat; via JPMorgan acting as an intermediary in this transaction
(hereinafter the "Intermediary"). For that purpose, RSL will transfer the said
share to Intermediary in in a separate Borrowing and Forward Purchase Agreement
(Exhibit 4 to this Agreement), and Intermediary will transfer the said share to
Seat in a separate Share Purchase (Contribution) Agreement (Exhibit 5 to this
Agreement).

By the present Agreement, Seat and RSL agree what shall apply between them in
connection with the above.

            Parties shall comply with such amended Articles of Association as of

            pursuant to Section 11 subparagraph 1 litt. a) below) should by then
            not yet be registered with the competent commercial register.

            typically be held by way of telephone-/video conferences. The party
            inviting to the meeting shall be responsible for drafting the
            minutes.

4.    Structure of the Holding / Obligation to not Sell Share

      In light of its role assumed in the Joint Venture, RSL undertakes that it
      will not wholly or partly dispose of its shareholding in the Holding in
      any way, be it by selling, transferring, encumbering, pledging or granting
      any other rights to third parties of whatever nature in its shareholding
      in the Holding to a third party. For each violation of this undertaking,
      RSL shall owe a penalty equal to the consideration that would have been
      applicable if the Put Option or the Call Option pursuant to the Option
      Agreement (Exhibit 3 to this Agreement) had been exercised (at the time of
      the violation), it being understood that Seat may claim from RSL any
      higher amount of damage which it can show to have occurred. Seat has also
      the right to claim from RSL to restore its full and unencumbered
      shareholding in the Holding, and to then transfer its shareholding in the
      Holding to Seat at 90 % of the afore-mentioned penalty.

      The Parties agree that the Holding shall continue to hold its present
      shareholding in Telegate. RSL and Seat will undertake in good faith

<PAGE>

      negotiations with a view to change the size of the shareholding of the
      Holding in Telegate, if that is necessary in order to allow Seat to
      acquire the Remaining Shareholding by way of a contribution in kind, as is
      nearer explained in Section 8 of this Agreement and in the Option
      Agreement (Exhibit 3 to this Agreement), provided that such change must in
      no way adversely affect the position of RSL in and with regard to the
      exercise of the options under the Option Agreement.

6.    Changes in Telegate's share capital

      In the event that during the term of the Joint Venture Telegate intends to
      increase its share capital in a manner leading to Holding holding only 50%
      or less of the shares in Telegate RSL shall have the opportunity of either
      subscribing shares on a pro-rata basis to its indirect shareholding (as a
      consequence of which the amount of shares in Telegate covered by the put-
      and call-option according to the Option Agreement shall be adjusted
      accordingly) or getting sufficient time, but not more than two months
      after a respective request of Seat (but in no case earlier than January 1,
      2001) to obtain consent of its bondholders allowing it to reduce the
      holding of Holding in Telegate to 50% or less. In the event RSL chooses to
      seek for the consent of its bondholders and the aforementioned period
      expires without RSL stating to Seat that approval has been obtained Seat
      shall be entitled to exercise its call-option under the Option Agreement.

                                    Section 2

                 The Majority-Conferring Share and its Transfer

Concurrently to the notarization of the present Agreement, Seat will notarize
the L Umbrella Agreement with, whereby Seat will acquire a shareholding of a
nominal DM 25,400 corresponding to approx. 49.8 % in the Holding. By virtue of
the present Agreement, Seat shall acquire an additional shareholding of approx.
1.6 % in the Holding (as nearer set forth in this Section 2) which additional
shareholding shall hereinafter be referred to as the "Majority-Conferring
Share".

<PAGE>

1.    The Majority-Conferring Share shall be a share in the Holding with a
      nominal value of DM 800 out of a total nominal share capital of the
      Holding of DM 51,000 and hence representing approx. 1.6 % of the share
      capital in the Holding. RSL shall create the Majority-Conferring Share by
      splitting its existing share in the Holding with a nominal value of DM
      25,600 into two shares with nominal amounts of DM 24,800 and DM 800 (the
      Majority-Conferring Share), respectively. Concurrently with the
      notarization of this Agreement, (i) RSL has declared the said split by the
      declaration shown in Appendix 2 to the Agreement for the Transfer of
      Shares attached to the Borrowing and Forward Purchase Agreement (Exhibit
      4); (ii) the Holding has approved of the said split, by the declaration
      shown in Appendix 1 to the Agreement for the Transfer of Shares attached
      to the Borrowing and Forward Purchase Agreement (Exhibit 4); (iii) and L,
      RSL and the Intermediary, each in its capacity as (future) shareholder of
      the Holding, shall approve of the transfers of the Majority-Conferring
      Share, by the declaration shown in Appendices 1, 3 and 4 to the Agreement
      for the Transfer of Shares attached to the Borrowing and Forward Purchase
      Agreement (Exhibit 4).

2.    The Majority-Conferring Share shall be transferred from RSL to the
      Intermediary by virtue of the Borrowing and Forward Purchase Agreement
      (Exhibit 4). The Intermediary shall transfer the Majority-Conferring Share
      further to Seat as a contribution in kind to the an increase of the share
      capital of Seat, through a Share Purchase (Contribution) Agreement which
      shall be notarized concurrently with this Agreement, which is attached as
      Exhibit 5 to this Agreement and pursuant to which the transfer to Seat
      shall become effective at the shortest possible interval before the newly
      issued shares shall in freely tradeable form be delivered to the
      Intermediary.

                                    Section 3

                                  Consideration

1.    The consideration for the Majority-Conferring Share, owed by Seat to the
      Intermediary (only), shall consist in shares in Seat in such number as is
      defined in subparagraph 2, and shall be due at such time as is defined in
      subparagraph 3.

<PAGE>

      The consideration for the Majority-Conferring Share, to which RSL is
      entitled against the Intermediary (only), shall consist in cash generated
      by the monetization of the shares due by Seat to the Intermediary, in such
      amount as set forth in subparagraph 4, and shall be due at such time as
      set forth in subparagraph 5.

2.    The number of shares in Seat due for the Majority-Conferring Share shall
      be calculated as follows:

      (i)   Firstly, it shall be established what number of Telegate shares the
            Majority-Conferring Share indirectly represents (Example: If there
            is a total of 12,730,000 outstanding Telegate shares of which the
            Holding owns 6,490,577 shares, and the Holding has a registered
            share capital of DM 51,000, then the Majority-Conferring Share with
            a nominal value of DM 800 shall represent 101,813 shares in
            Telegate);

      (ii)  Secondly, the value of the shares in Telegate and Seat shall be
            assessed. (a) For this purpose, the value of each share in Telegate
            shall be deemed to be the higher of (aa) 150 and (bb) the official
            closing price as published by Bloomberg for Telegate shares on the
            Frankfurt Stock Exchange one day prior to the notarization of this
            Agreement (hereinafter "T.May3"); whilst (b) the value of each share
            in Seat shall be the Official Closing Price ("Prezzo di
            Riferimento") as published by Bloomberg for Seat shares on the Milan
            Stock Exchange one day prior to the notarization of this Agreement
            (hereinafter "S.May3").

      (iii) By comparing the respective values, which is to be done by dividing
            (a) the higher of (aa) 150 and (bb) T.May3 by (b) S.May3, the number
            of Seat shares is obtained which correspond to one Telegate share.

3.    Seat shall transfer such number of Seat shares as result from the above
      calculation to the Intermediary at such moment when an according number of
      Seat shares will be available following

      (i)   a resolution, to be passed at Seat's extraordinary shareholders'
            meeting scheduled to take place on or around June 30, 2000, whereby
            the registered share capital of Seat shall be increased by such an
            amount and in such ways as is necessary to allow Seat to provide the
            Intermedi-

<PAGE>

            ary with such number of new Seat shares as will be owed as
            consideration for (i) the Majority-Conferring Share, and (ii) the
            Shareholding as defined in and pursuant to the L Umbrella Agreement;
            and

      (ii)  the completion of such additional steps as are required under
            Italian law for making the new shares resulting from the said
            shareholders' resolution on the capital increase, available as
            freely tradeable shares.

      The Parties expect the said new Seat shares to be available as freely
      tradeable shares on or around August 7, 2000. If this is not the case by
      October 15, 2000, Section 4 subparagraph 3 shall apply.

4.    RSL shall receive from the Intermediary a cash amount for the
      Majority-Conferring Share which is to be calculated as follows
      (hereinafter the "Cash Equivalent"):

      (i)   Firstly, it shall be established (the same way as in subparagraph 2
            (i)) what number of Telegate shares the Majority-Conferring Share
            indirectly represents;

      (ii)  Secondly, the price of the Telegate share shall be deemed to be the
            higher of (aa) 150 and (bb) the closing price as published by
            Bloomberg for the Telegate share on the Frankfurt Stock Exchange one
            day prior to the notarization of this Agreement;

      (iii) Thirdly, the number of Telegate shares represented by the
            Majority-Conferring Share (subparagraph (i)) shall be multiplied
            with the price of the Telegate share as resulting from subparagraph
            (ii).

5.    The Intermediary shall pay the Cash Equivalent into an escrow account two
      banking days after the notarization of the Borrowing and Forward Purchase
      Agreement (Exhibit 4). The escrow shall be released to RSL, including the
      interest accrued, on the earlier of (i) such day when Seat shall transfer
      the new Seat shares to the Intermediary, pursuant to subparagraph 3, and
      (ii) October 16, 2000 provided Seat decides to uphold this agreement
      pursuant to Section 4 No. 3 (b).

6.    The Intermediary is not a party to this Agreement. All arrangements which
      need to be made between the Intermediary and Seat, and between the
      Intermediary and

<PAGE>

      RSL in light of the provisions of this Section, are contained in the
      Borrowing and Forward Purchase Agreement to be notarized by RSL and the
      Intermediary concurrently with the notarization of this Agreement (Exhibit
      4), and in the Sale and Purchase (Contribution) Agreement to be notarized
      by Seat and the Intermediary concurrently with the notarization of this
      Agreement (Exhibit 5).

            substantially within such terms and under such conditions as are
            customary in the industry.

<PAGE>

            have been no material adverse changes in the financial situation of
            the Companies.

      h)    Governmental Approvals, Licences and Permits, Compliance with Laws

            The current operations and activities of the Companies including
            without limitation their current operations and activites in the
            five business core areas (i) data (enrichment, combination and
            sale), (ii) internet, (iii) telephony (technical operations), (iv)
            TIS (telephony information services) and (v) CCS (call center
            services) are, to the best knowledge of RSL, all in compliance in
            all material respects with all laws and governmental regulations and
            orders.

            the the assignment of call numbers or the possession of governmental
            approvals, licences or permits (including all material approvals,
            licences or permits as may be required under applicable
            telecommunications laws, and including the assignment of the call
            numbers "11880", 11887", "11890" and the interconnect access code
            "01080"(provided however that the interconnect access "01080" is
            currently not used by Telegate and may therefore be revoked), such
            approvals, licences or permits are all being held by the respective
            Companies. Such assignments, approvals, licences and permits are in
            full force and effect and will not be terminated due to the
            transactions contemplated in this Agreement. RSL and Telegate do not
            know of any circumstances which could justify a revocation of these
            assignments, approvals, licences or permits. The conditions
            ("Bedingungen" and/or "Auflagen") accompanying these approvals,
            licences and permits have been complied with in all material
            respects.

      i)    Essential Agreements

            The interconnection agreement dated December 12, 1999 and the
            billing agreement dated October 12, 1998 Telegate has entered into
            with Deutsche Telekom AG (hereinafter together the "Essential
            Agreements") are all in full force and effect pursuant to the terms
            and conditions thereof, and enforceable in accordance with their
            terms and conditions against the other parties thereto, except as
            enforcement

<PAGE>

            thereof may be limited by applicable bankruptcy, insolvency,
            reorganization, moratorium or other similar laws affecting the
            rights of creditors. Neither Telegate (or any other of the
            Companies) nor the other parties are in default in any material
            respect under any material provision of the Essential Agreements.
            The Companies are not aware that the other party to any of the
            Essential Agreements has any intention not to continue any of the
            Essential Agreements as currently practised.

            Schedule 5 i shows a list of all agreements entered into by any of
            the Companies which require (irrespective of whether such agreements
            are considered Essential Agreements) a yearly expenditure in excess
            of DM 1,000,000 (DM One Million) or which cannot be terminated with
            one year's notice at the latest.

      j)    Trademarks, Know-how, Other Intellectual Property Rights and Domain
            Names

            The Companies are the owners of all know-how the Companies use in
            their businesses. Telegate is the owner of the trademark "Telegate"
            (all together hereinafter "Intellectual Property Rights"). Seat is
            informed about the current status of registration concerning the
            registered and applied for trademarks. All Intellectual Property
            Rights are free of liens and encumbrances by third parties. The
            Companies need not to rely on licence-agreements with third parties.

            The Companies are the sole and lawful owners, and do not need to
            rely on licences, of those of the internet domain names
            "telegate.com", "telegate.de", "travelgate.de" and "11880.com",
            which internet domain names are in each case clear and free of all
            liens, encumbrances and any other rights of third parties.

            To the best knowledge of RSL, there are no claims by third parties
            challenging any of the Company's rights or title, nor are there any
            factual violations, in each case with regard to any of the
            trademarks, domain names, know-how or other intellectual property or
            name rights of the Companies, or any products which are currently
            being developed in the Business.

<PAGE>

            To the best knowledge of RSL, the trademarks, domain names, know-how
            or other intellectual property or name rights of the Companies, and
            their use do not infringe any third party's rights.

      k)    Technical Equipment

            All technical equipment used by the Companies in carrying out their
            businesses, whether owned, leased or licensed, and including without
            limitation computer hardware, computer programs, switches and all
            other devices, is in good working order and is sufficient to cover
            substantially all current needs of the businesses of the Companies.

      l)    Employees

            All key employees of the Companies have been hired in the ordinary
            course of business. There have not been any written or oral promises
            of pay rises or any other additional remuneration to any of the key
            employees. There are no outstanding payments of salaries, bonuses,
            vacation pay, social insurance contributions and all other payments
            due under the employment relationships. No key employee at any of
            the Companies has made known the intention to leave. RSL or
            companies affiliated to it (other than the Companies) have not
            offered employment to any key employee of any of the Companies. No
            key employees have been given a right to receive a severance payment
            in case of termination of their employment agreements exceeding the
            rights provided for by statutory law or collective bargaining
            agreements, nor have the members of the management board of Telegate
            been granted any such right to receive a severance payment in cash
            or in kind. There is no labor litigation with any of the employees
            of the Companies exceeding in the individual case a value of DM
            100,000; and all labor litigation does in the aggregate not exceed a
            value of DM 500,000. Schedule 5-l shows a complete list of all
            material shop agreements ("Betriebsvereinbarungen") which the
            Companies have stipulated with the competent works councils. The
            Companies are, on the date hereof, not engaged in any material legal
            dispute with trade unions, shop councils or any other employees
            organizations.

<PAGE>

      m)    Insurances

            The Companies have taken out, for insured sums as are in accordance
            with applicable market standards, all the insurances which are
            mandatory under the law and all such other insurances as are
            appropriate or customary in the type of business as conducted by the
            Companies, and all insurance premiums have timely been paid.

      n)    Taxes

            The Companies have filed all tax returns, which returns are complete
            and correct in all material respects, required to be filed by them
            or on their behalf with any tax of governmental authority in any
            jurisdiction; and have paid in full all federal, state, local or
            foreign taxes, levy, impost, fees, duties, fiscal and social
            security and similar charges, including any interest and penalty
            thereon (collectively "Taxes") shown on such returns or for which
            they have been assessed, or have, with regard to all Taxes that are
            or may become due but have not yet been paid, made adequate accruals
            on their books, in accordance with generally accepted accounting
            principles applicable in the respective jurisdiction; and none of
            the Companies is engaged in a dispute with any tax or social
            security authority.

            Upon request of RSL, Seat shall cause the Company concerned to
            appeal at the cost of RSL and in accordance with its instructions,
            against tax assessments if such appeal may result in taxes being
            reimbursed to or not to be paid by the respective Company. In order
            to enable RSL to properly assess the chances of such an appeal and
            to proceed with such appeal, Seat shall cause the respective Company
            to make available to RSL all relevant information and documentation.
            The respective Company may settle with the consent of RSL only which
            consent will not be unreasonably withheld.

      o)    No Impediments

            There are no material legal or factual impediments preventing the
            Companies from carrying on their businesses to the extent and in the
            manner hitherto conducted, and there are no material unfulfilled
            obligations

<PAGE>

            imposed on the Companies by the authorities with respect to their
            businesses.

      p)    Litigation

            The Companies are not involved as plaintiff or defendant or as a
            joined party in any litigation, including arbitration proceedings or
            administrative proceedings, with a litigation value exceeding in the
            aggregate DM 5,000,000, nor has any such litigation, including
            arbitration proceedings or administrative proceedings, been
            threatened to the Companies, or is there a foreseeable need to take
            recourse to litigation, except in all cases as set forth in Schedule
            5 p.

2.    Section 460 of the German Civil Code (BGB) shall apply mutatis mutandis.
      Seat is deemed to know such documents which were contained in the data
      room in Planegg which was made accessible to representatives and advisers
      of Seat on March 28 and 29 and April 26 and 27 and May 2, 2000 which are
      listed in the list attached to this Agreement as Schedule 5.2.

3.    The above guarantees shall be deemed to be repeated by RSL also as of the
      time when the transfer of the Majority-Conferring Share to Seat becomes
      effective (Section 2 subparagraph 2), provided that (i) before such date
      RSL will have been given a reasonable opportunity to discuss with one or
      several members of the board of directors (Vorstand) of Telegate whether
      the above guarantees are still true, complete and correct in all material
      respects, and (ii) will have been provided by the management with a
      statement thereon. To the extent that RSL, as a result of the said
      discussion, makes specific limiting qualifications the above guarantees
      shall not be deemed to be repeated.

                                    Section 6

                       Liability for Breach of Guarantees

1.    If any of the guarantees given by RSL in Section 5 proves to be partly or
      wholly incorrect, the Party which learns first about such incorrectness
      shall inform the other Party thereof. For a period of 90 days starting
      with such

<PAGE>

      information, RSL shall have the possibility to cure the breach by
      restoring a situation where the guarantee is true.

2.    If RSL is unable to cure the breach or does for other reasons not cure the
      breach, RSL shall indemnify Seat for the amount that would have to be
      spent to fully restore the factual situation to the guaranteed situation
      ("damage"), limited, however, to a part such amount (as defined in
      subparagraph 3), which shall be paid, at RSL's choice, to either the
      Company or Companies to which the guarantee which is breached has the
      closest connection, or to Seat. If the payment of an indemnification
      occurs at such a time when the Joint Venture as agreed in Section 1 should
      no longer exist or where a Put Option Acceptance Declaration or a Call
      Option Acceptance Declaration has been made pursuant to the Option
      Agreement (Exhibit 3), any amount pursuant to this subparagraph shall be
      paid, at Seat's choice, to either the Company or Companies to which the
      guarantee which is breached has the closest connection, or to Seat.

3.    Whilst Seat shall have the right to recover full damages pursuant to
      subparagraph 2 from RSL and L in the aggregate (the latter gives Seat, in
      the L Umbrella Agreement, the same guarantees as are in this Agreement
      given by RSL), each of RSL and L shall only be severally liable for the
      damages. Of each damage, RSL shall bear a part of 25.6/51 (approx. 50.2%)
      and RSL shall bear a part of 25.4/51 (approx. 49.8 %).

4.    Where guarantees are given subject to the (best) knowledge, RSL shall be
      deemed to have the same knowledge as L has (and L shall, in the L Umbrella
      Agreement, be deemed to have the same knowledge as RSL has).

5.    The amount of the liability of RSL for breaches of guarantees shall be
      limited as follows:

      (i)   In calculating the aggregate liability of RSL and L, only such
            individual breaches of guarantees shall be taken into account which
