Formation of Newco

1.    Dr. Levy and Swiftnet Ltd. (Swiftnet) (or assignees) will establish a
      company - Newco - for the purpose of developing telecommunication business
      based on Non-Geographical Numbers.(1)

2.    For the first stage the budget will not exceed the amount of
      (pound)100,000. Any increase of the budget will require both parties'
      approval.

3.    Dr. Levy will finance by way of a loan, 75% of the ongoing expense for one
      hundred percents of the shares.

4.    Swiftnet Ltd. Will finance by way of a loan, 25% of the ongoing expenses
      and provide cost plus prices(2) as well as management advise and technical
      support (customer support for the first two months) for an option, at any
      time, to receive 50% of the shares of Newco or in case of a dilution, to
      receive the same amount of share as Dr. Levy. Swiftnet can assign this
      option to any assignee as long as Swiftnet continues to provide the
      service according to the agreement. Swiftnet will sell the service to
      Newco and will be responsible for the technical side. Swiftnet will do its
      best to make the service available to Newco within 90 days. Swifnet
      undertakes to exhibit to Newco all licenses or other permissions /
      documents necessary for the operation of its business.

5.    Newco will repay the loan only from net profits. Any decision about
      repayments will have to be decided by the board of directors with veto
      rights to both sides. In case Swiftnet does not exercise its option, it
      will be entitled to management fees equal to the monies that Dr. Levy will
      be entitled to receive from Newco. It is further agreed that once the
      loans are repaid, Swiftnet and Dr. Levy (or assignees) will be entitle to
      the exact same amounts as a fee / profit share. This does not include
      payment to Swiftnet for service, office rent charges to Swiftnet / Dr.
      Levy or other similar expenses. Before any profit distribution, all loans
      that are related to the parties will have to be paid back.

                                                                          /s/ AK

6.    Dr. Levy and Swiftnet, if possible, will allow Newco to use their
      respective offices for a 2-month duration without cost.

----------
(1)   Activities/Services: Use of Swiftnet premium numbers bands for customers
      to call international or national destinations paying BT directly while BT
      pays the company (through Swiftnet).
(2)   Calculated by carrier cost + 15 percent to cover costs like E1's rent,
      necessary infrastructure and 24H technical support lines.

7.    Unless agreed by the Newco board of directors or in the case of Newco
      seizing operation or not using Swiftnet for its services or not achieving
      a minimum of 50,000 pounds per month turnover in 1 year's time, Swiftnet
      and Dr. Levy as well as companies owned / controlled by Swiftnet and Dr.
      Levy will not engage in the same Telecommunications activities (as
      described in the first page footnote) outside of Newco.

8.    Newco will receive ten percent of paid turnover of customer that it will
      introduce to Swiftnet, except for Mobile phones where the percentage will
      be seven. Swiftnet had the right to reuse a customer or to renegotiate
      percentage fee for large customers with low margins.

9.    Newco will have the right to sell other services and products that
      Swiftnet offers or will offer in the future for the best wholesale price
      available.

10.   The company board of directors will be comprised of 5 members; 2 nominated
      by Swiftnet, 2 by Dr. Levy and the managing director. All decisions
      (Expenses, recruitments, strategy, investments, dilutions, dividends,
      marketing initiatives, accounting, finance etc.) will be made by the board
      of directors and will not be valid without signed minutes with signatures
      from at least one representative from each side. In order to conduct a
      meeting, a quorum of three directors, as long as there is one from each
      side, will be sufficient. Signed proxies are also allowed. Both side will
      have full veto rights on any decision in the board or outside the board.
      Veto rights will be effective immediately and must be exercised in
      writing.

11.   Newco will operate according to an agreed Business plan (by a board
      resolution) and decide on each investment and expense based on the
      viability of the opportunity. The initial business plan will need to be
      approved before Newco starts its operations.

12.   Both parties will make available their contacts, connections and influence
      for the success of Newco.

13.   This agreement will be governed with accordance to the English law.

                                        /s/ A. [ILLEGIBLE]

                                 SNARC ADDENDUM
                           ITXC.NET SERVICES AGREEMENT

      THIS  ADDENDUM  ("Addendum")  is  attached to and made a part of a certain
ITXC.Net  Services  Agreement  entered  into on February 20, 2003 by and between
ITXC Corp, a Delaware  corporation  ("ITXC") and Swiftnet  Ltd.  ("Company"),  a
______  corporation,  (collectively  the "Parties" or  individually  a "Party"),
(Capitalized  terms used and not defined  shall have the same meanings set forth
in the Agreement.)

      1. DEFINED TERMS. Unless the context otherwise requires  capitalized terms
used and not defined herein shall gave the meanings set forth in the Agreement.

      2. ITXC EQUIPMENT. Upon execution of this Addendum, ITXC at its sole cost,
shall  purchase  and  furnish to  Company  the  equipment,  it deems at its sole
discretion to be reasonably  necessary to assist  Company in the  performance of
its obligations hereunder,  including, without limitation, IP telephony gateways
(collectively,  the "ITXC Equipment"), which Equipment includes the items listed
on Exhibit C to this Addendum, to be collocated with Company's switch. The items
of ITXC  Equipment  (gateways)  in  connection  with the services to be provided
hereunder,  shall be determined based upon the projected traffic to be exchanged
by the  Parties.  ITXC  reserves  the right to  increase  or  decrease  the ITXC
Equipment in connection  with the Services.  ITXC shall provide  Company with at
least 5 days notice if the ITXC  Equipment  is to be  increased  and at least 10
days notice if it will be decreased [except where otherwise provided].

      3.  SERVICES TO BE  PROVIDED.  In addition to the  Services to be provided
under  the  Agreement,  ITXC  shall  provide  remote  management,   maintenance,
operation and support of the ITXC Equipment and any related equipment.

      4. COMPANY SERVICE RESPONSIBILITIES. Company is responsible to provide, at
its own cost and expense,  the necessary amount of bandwidth,  PSTN lines, clear
channel IP data lines, hubs, routers,  switches, and any additional equipment or
facilities as may be required to meet the gateway capacity  provided by the ITXC
Equipment.  ITXC shall provide  Company with a written  request  specifying  the
amount of bandwidth and lines necessary for the ITXC Equipment.  Company further
agrees that the ITXC  Equipment  shall be dedicated to ITXC traffic only and may
not be used for any other Company's traffic.  In the event of failure by Company
to comply with the terms of this provision,  it shall be deemed a default of the
Agreement, and ITXC may immediately suspend Services or terminate the Agreement.

      5. OWNERSHIP OF EQUIPMENT/FACILITIES.

            (a) Title to the ITXC Equipment shall at all times remain with ITXC.
None of the ITXC Equipment shall be, and none shall be deemed to be, property of
the Company.  Company  agrees to execute any documents  reasonably  requested by
ITXC to evidence ITXC's continued ownership of the ITXC Equipment. No portion of
the ITXC Equipment, including without limitation, any gateways, lines or related
equipment shall be deemed a fixture, notwithstanding any method of affixation to
the  property,  premised  or the  building  or any  applicable  law or  doctrine
relating to fixtures.

            (b) Company  acknowledges  and agrees that ITXC has located the ITXC
Equipment in Company's premises solely as an accommodation to Company.  Under no
circumstances  shall  Company  represent  to any person that  Company  owns,  or
removes any  identifiers  of ITXC's  ownership on, the ITXC  Equipment.  Company
covenants  that it will  not  assert  (i) any  ownership  interest  in the  ITXC
Equipment, or (ii) any right to own, possess, hold or retain the ITXC Equipment.

            (c) In the event  Company  shall  file,  or become the subject of, a
petition  seeking relief under any applicable  bankruptcy  laws,  Company agrees
that it will not assert that the ITXC Equipment is property of Company's estate.
Company  further  agrees that,  to the extent that an automatic  stay or similar
provision is applicable to ITXC or the ITXC Equipment,  Company,  for itself and
its successors and assigns, will not oppose any request by ITXC to obtain relief
from such  provision,  and at ITXC's  request,  will consent to such relief,  in
order to permit ITXC to preserve and protect the ITXC  Equipment  and further to
permit ITXC or its agent to remove the ITXC Equipment from Company's premises.

            (d) In the event  that the ITXC  Equipment  is  damaged,  destroyed,
rendered  inoperable,  removed without the express  authorization of ITXC and/or
returned upon request by ITXC,  then Company shall be liable for the replacement
cost of the  ITXC  Equipment  and ITXC  shall  have the  right  to  offset  said
replacement cost against any amounts owed by ITXC to Company.

            (e) If Company is in default under the  Agreement or this  Addendum,
then in addition to any of the remedies  contained in the Agreement,  ITXC shall
reserve the right to suspend service and remove the ITXC Equipment  immediately,
without  notice  or  any  further  liability  to  Company.  Notwithstanding  the
foregoing, if Company is in default due to any insolvency, bankruptcy assignment
for the  benefit of  creditor,  appointment  of a trustee or receiver or similar
event with respect to the Company,  then ITXC shall have the right to remove the
ITXC Equipment immediately,  without notice to Company, and if necessary ITXC or
its vendors may enter the premises, as well as access to any conduits, chaseways
or other  areas,  where such  items are  located  and remove the ITXC  Equipment
without prior notice to the Company. ITXC shall have no liability to Company for
such removal.

      6. COMPANY'S RESPONSIBILITIES WITH RESPECT TO THE ITXC EQUIPMENT.

      Company shall: (a) provide  technical  personnel within 2 business days of
receipt of ITXC  Equipment  in order to support  ITXC in the basic  installation
procedures  required for the ITXC  Equipment;  (b) operate the ITXC Equipment in
strict compliance with ITXC's technical  documentation;  (c) not alter or modify
ITXC Equipment except as specifically  prescribed by ITXC; (d) extend a standard
of care for the ITXC  Equipment no less  stringent that the Company uses for its
own  equipment,  but in no event  less than a  reasonable  degree  of care;  (e)
include the ITXC Equipment in any insurance policy against loss, theft or damage
that the Company has for its own  equipment or  facilities  and provide ITXC, at
ITXC's request,  of proof of such  insurance;  and (f) provide ITXC or its agent
with  access at all times to any space that ITXC or its agent  requires  for the
maintenance  of  ITXC's  Equipment,  facilities  and  lines or  removal  of ITXC
Equipment.  In  addition,  in the event  that the ITXC  Equipment  is reduced or
removed,  the Company will use  reasonable  care and fully  cooperate in removal
activities,  including packing and return shipping of the ITXC Equipment back to
the ITXC-designated location.

      7. COMPANY COMPLIANCE FOR CUBA.

      Company  acknowledges that Company,  its agents and/or through third party
agreements are providing  their own and/or third party equipment for termination
in Cuba and in no case  shall  ITXC  engage in any  transaction  (including  the
negotiation  of any contract  term)  related to the  exportation  to Cuba of any
equipment  from the  United  States  or from a third  country.  Company  further
acknowledges  that  payments  for calls  terminating  in Cuba  shall not  exceed
existing U.S.  guidelines  (currently a $0.60 per minute settlement rate, plus a
$1.00  surcharge per message for collect  calls  originating  in Cuba),  whether
payment  is made  directly  to ETECSA or  indirectly  through a Foreign  Service
Provider (FSP).

      8. SECURITY.

      INTENTIONALLY LEFT BLANK.

      9. NO MODIFICATION;  CONFLICT. Except as specifically modified and amended
herein, all terms and conditions of the Agreement are hereby ratified and remain
in  full  force  and  effect.  Company  hereby  reaffirms  all  representations,
warranties and covenants  contained  herein.  In the event of a conflict between
the terms of this  Addendum  and the  Agreement,  terms of this  Addendum  shall
control.  This  Addendum  may not be  modified  except in writing by  authorized
representatives of the Parties.

5.    CHARGES, BILLING AND PAYMENT.

agreement  whereby  Company  shall  provide  Termination  Services  as  well  as
Origination Services, this Section 5.1 shall control invoicing and payment. ITXC
or its agent  shall issue an invoice to Company on a weekly  basis (the  "Weekly
Invoice"). All amounts stated on each Weekly Invoice shall be due and payable in
full  within  seven (7) days from the Weekly  Invoice  date.  Company  shall not
dispute any of the charges  contained on the Weekly  Invoice unless such dispute
is in good faith,  is greater than or equal to 10% of the total amount  invoiced
by ITXC and Company provides written notice to ITXC.  Disputed amounts less than
10% shall be  disputed  by Company  as part of the  monthly  settlement  process
described herein. At the end of each month, ITXC will provide Company with a net
settlement Invoice (the "Net Settlement  Invoice") containing for the applicable
billing  period  and for any prior  period  that  appropriate  charges  were not
invoiced  (i) the  Termination  Services  Value,  if any,  (ii)  the  WWeXchange
Services  Value,  if any and (iii) the  Settlement  amount.  Each invoice  shall
include the total  payment due for Units of Service for the  applicable  billing
period and for any prior period that  appropriate  charges  were not  reflected.
Once  Company  has  received  the monthly Net  Settlement  Invoice,  Company may
dispute  charges of the Weekly Invoices  covered by such Net Settlement  Invoice
(the "Monthly Settlement Process").

5.2 Unless ITXC receives  written notice from Company that the amount on the Net
Settlement  Invoice does not accurately  reflect applicable charges for Services
for the period,  then Company  shall pay the amount shown on the Net  Settlement
Invoice within 7 days of the date of such statement. Any undisputed payments not
made when due are subject to a Late  Charge of 1.5% or LIBOR plus 1%,  whichever
is lower.

5.3 ITXC's records shall be utilized for billing purposes. Company shall provide

within the  30-day  period.  In the event  that  Company  disputes  billing  and
withholds  payment,  ITXC may suspend or reduce  services during the pendency of
such disputes to prevent Company from accumulating  charges and liability during
the dispute resolution. All amounts in dispute shall be counted toward Company's

invalid,  then  Company  shall be subject to a Late Charge of 1.5% or LIBOR plus
1%, whichever is lower.

reasonable methods consistent with industry practice. If any dispute between the
Parties is not  resolved  within 10 business  days after  written  notice as set
forth in Section 5 of the Agreement,  and any disputed  amount has been withheld
pending  resolution  of such  dispute,  then the Parties  may begin  arbitration
proceedings  under  Section 12 of the  Agreement.  If either  Party brings legal
action  for the  recovery  of any  amounts  due from the other  Party  under the
Agreement,  the non-prevailing Party shall pay the prevailing Party's reasonable
attorneys' fees,  collection fees and costs actually  incurred by the prevailing
Party.

6. FEES.  Company  shall pay to ITXC the  Network Fee in the amount of $5,000 on

described  below.  Payment of such fee is required  before the  commencement  of
