                        numbers from active users that generate CDR's managed by
                        the Operator. Thus in the residential case, there may be
                        one or two telephones for each residential user. A large
                        corporate subscriber though (even though they are one
                        corporate subscriber) will actually have many telephone
                        numbers in their VPN and it is these
                        subscribers/telephone numbers that should be used in the

Analysis, Implementation, HW/SW Installation & Configuration and Acceptance
Test. These four phases are divided into ten Work Packages (WP) which in its
turn is divided into several activities and sub-activities. The Work Packages
are more closely described in section 2.4 in Appendix I of this document. The
time plan also identifies project milestones which are to be met during the
project. For the implementation project the following set of milestones has been
set up.

1     EuroTel Objectives

This section 1 provides a high level description of EuroTel's objectives
regarding the BMD.

1.1   High Level Requirements

The following bullet points cover the high level requirements of the BMD
solution required for EuroTel. They are as follows:

o     Revenue assurance - full control of CDR's processing with auditable logs
      of transactions from call collection through each step.

o     Independence in BMD system from network elements output formats.

o     Open architecture

o     Preparation for seamless transition to HSCSD, GPRS, UMTS technologies.

o     Easy expandability due to the modular structure of the BMD to make it easy
      to meet the future growth both in terms of volume and new services

o     The reduction in the number of 'extra' processing steps outside of the
      core BMD functionality.

o     No manual work, apart from normal system administration

o     A high degree of error detection due to the automated validation.

o     Seamless integration with the current systems and infrastructure

o     Graphical user interface

o     Development tools

o     Monitoring features

o     High availability of the system 24*7 operations

o     Source code availability is included in the Scope of Delivery of the
      specific EuroTel customizations that are delivered by the project.

o     Single source for different applications required for CDR analysis e.g.
      searching engine for security entities.

1.2   Scope of specification

By implementing the solution, EuroTel Bratislava intends to simplify the
processes and interfaces to be able to minimize or replace many of today's
components.

--------------------------------------------------------------------------------
                                                                      Appendix I
                                                               Scope of Delivery

The main interfaces for the BMD shall be:

Input

      o     Ericsson AXE MSC's (GSM1,2&3)

      o     Nokia Switches (NMT1&2)

      o     SMS centres (SMSC)

      o     Roaming (TAP3 from MACH & TAP2+ from EuroTel Prague)

      Data from Network Elements is requested by polling and two types of
      polling are included. One is set by the clock and the frequency can be
      from one minute up to 24 hours. The other is event driven whereby the BMD
      will fetch the CDR file right after it has been created in a directory.

Output

      o     SICAP replacement of CDR handler and DB loader. BMD will mediate
            ASN.1 data to SICAP system.

      o     CDR Loader replacement- BMD will mediate data as input to
            Interconnect, VOIP, Security and FDS system..

      o     BSCS interfacing RIH modul

The aim is also for the BMD to reduce the number of standard modules used in the
existing systems hence improving performance. The following BSCS processes will
be replaced:

      -     File Input Handler (FIH)

      -     Duplicate Record Handler (DRH)

      -     Assembled Input Handler (AIH)

By using a new BMD based on standard BMP mediation functionality, the following
utilities and programs will be realized within the solution:

o     In-house developed CDR Collector
            The present CDR Collector used by EuroTel will be replaced by the
            standard BMP Collection functionality as defined in section
            2.4.3.(WP3 Collector Set-up) and subsection Formatting in section
            2.4.5. (WP5 Processing).

o     Splitter
            Filtering of post-paid and pre-paid CDRs will be handled using the
            standard BMP processing nodes described in section 2.4.5. (WP5
            Processing). Pre Paid Number Duplicity is not allowed: This is
            supported by the Duplicate CDR Detection functionality which is a
            standard processing node in BMP

o     Voice Mail/Fax Mail converter
            CDR based on Voice and Fax Mail activity will be processed and
            converted to the required output format using standard BMP
            processing nodes described in section 2.4.5 (WP5 Processing).

                                                               Scope of Delivery

o     SMS converter
            CDR based on SMS activity will be processed and converted to the
            required output format using standard BMP processing nodes described
            in section 2.4.5 (WP5 Processing)

o     TAP conversions
            BMP can handle the TAP2+ and TAP3 formats and process such CDRs
            using standard BMP processing nodes described in section (WP5
            Processing).

o     Star numbers
            BMD will convert Star numbers to regular numbers and distribute them
            to the BSCS system.

o     Inter33calls (Voice over IP - VOIP)
            BMD will convert Voice over IP numbers with prefix 33 to differerent
            prefix based on criteria.

Following investigation during the implementation analysis (WP2), and, where
necessary, a separate quotation from CGE&Y, the following functionality (but not
limited to) may be included or enhanced above what already is part of the scope
of delivery in the BMD. The first 5 mandays of change request work are included
free of charge provided that they are ordered within the project delivery time.

      o     Functionality to handle Audio text services

      o     Assistant Services

      o     Others as will be specified in Implementation Analysis

The final picture, which is much more simple than that of today, uses the BMD as
the core of the future architecture. It is shown in the following diagram.

Selection

The selection function streams or filters CDR's to other processing nodes or to
a file for further distribution to an external system.

30 General selection nodes for six (6) different output streams to the PPS'

Validation

The validation function performs validation on usage data on two levels: format
validation and business rule validation.

6 Validation nodes for each input format:

Sequence Number Validation

The sequence number validation function performs validation on one defined
sequence field in the usage data.

The sequence number validation function determines the validity of the current
sequence field value in comparison with the previous CDR.

3 sequence validation nodes

Sequence Number Validation is a functionality that is based on that the switches
mark every CDR with a sequence number. This number can be checked by BMP and if
one or more CDR's that are "out of sequence" is detected BMP will log this in
the error log and/or stop the processing. Since each switch uses its own
sequence numbering this normally is a functionality used for each switch
separately.

Enhanced Processing

The Enhanced Processing Node makes use of a script language called TCL or Java.
The capability of using a programming facility enables BMP to implement
requirements that cannot be implemented using BMP Basic Processing.

It is assumed that a number of Basic Processing Nodes and Enhanced Processing
Nodes will be implemented in order to comply with EuroTel's requirements. A
detailed design of the solution will be agreed upon during the implementation
analysis and documented in the Functional Specification and the Operational Jobs
Report draft.

Enhanced Processing - Consolidation

Enables handling of partial CDR's, merge the partial CDR's belonging to the one
and same chargeable call into one CDR for further processing in billing system.

Consolidation solution for 1 input format

To obtain final acceptance of the system, an acceptance test will be performed.
EuroTel is responsible for conducting the acceptance test.

The purpose of the acceptance test is to result in an approval of the delivery.
Approval of the delivery shall be executed or considered to be at hand, when any
of the criteria mentioned below and in the General Terms & Conditions
Responsibility Project has been fulfilled.

The parties shall agree on the contents of the acceptance test specification,
which shall contain a description of each planned test case and the desired
result. EuroTel's acceptance or rejection shall only depend upon the result of
the test cases specified in the acceptance test specification.

CGE&Y provides the acceptance test specification, including suggestions for test
material to be provided by EuroTel. EuroTel shall approve the acceptance test
specification. If EuroTel does not approve of the plan, objections must be
submitted to CGE&Y within one (1) week after reception. If no objection has
reached CGE&Y within one week, the acceptance test specification will be
considered approved. If EuroTel raises objections CGE&Y shall consider such
objections and adjust the test specification to a reasonable extent. In case of
rigorous objections or different opinions on the acceptance test specification
the issue shall be resolved by the Steering Committee in a meeting within seven

when EuroTel informs CGE&Y that EuroTel will not approve the acceptance test
specification proposed by CGE&Y. Should the Steering Committee fail to have the
parties to agree on the acceptance test specification then CGE& shall be
entitled to an extension of the delivery time. If the scope of the acceptance
test is increased CGE&Y shall analyse the consequences and inform EuroTel about
the extent of the required extension.

The acceptance test shall be completed within eleven days from CGE&Y's Delivery
for Acceptance.

CGE&Y shall correct defects discovered during the acceptance test or at the
delivery, provided that EuroTel has notified CGE&Y of the defect without delay.

Notified defects shall be categorised into three different types:

Severe Defects preventing further acceptance testing

Substantial Defects not preventing further acceptance test but necessary to
correct in order to take the system into operation

Minor Defects not preventing further acceptance testing or a meaningful
operation.

Severe and Substantial Defects shall be corrected before or during the
acceptance test. Delays in testing as a result of Severe and Substantial Defects
will extend the time for acceptance testing at CGE&Y's expense.

In the acceptance test a performance test shall be included. EuroTel and CGE&Y
shall agree on the hardware configuration that EuroTel will acquire, the level
of pre-defined performance criterias and test cases. If the stated performance
is not reached during the test CGE&Y shall take actions, without unreasonable
delay, to correct the problems identified. If the actions taken do not result in
passing of the performance test, CGE&Y will cover the cost necessary to upgrade
the hardware to a version that will make it possible to pass the performance
test. CGE&Y will also cover any costs related to software modifications or
purchase and installation of additional software and additional work that is
needed to pass the performance test.

All defects shall be corrected without unreasonable delay. Minor Defects shall
not prevent acceptance or approval and may be corrected during the warranty
period.

Defects and deficiencies that occur after the Final Acceptance shall be handled
according to the warranty conditions.

The acceptance will be completed when the Certificate of Final Acceptance (CFA)
is signed by EuroTel or it will be regarded as accepted and approved, as set out
in the General Terms & Conditions in Enclosure 2.

Activities:
Prepare site and participants for testing
Execute acceptance test according to Acceptance test procedure and Acceptance
test specification.

2.4.10 BSCS to BMP connection

The implementation of a connection between the BMP and BSCS software is included
in the scope of this agreement. The BMP will take over the CDR file conversion
to UTX format (conversion previously performed by the BSCS FIH batch process).
BMP will replace the FIH, DIH, DRH and AIH processes in BSCS.

Overview

The BMP collects CDR files from all MSC using the protocol for Ericsson and
Nokia switches. After converting CDR's to internal format the BMP needs to
perform all checks that the FIH used to perform. This is done during the
processing phase using TCL/JAVA programming. Then the CDR files will be
converted to UTX format and stored directly on the BSCS server.

Decoding

The BMP decoder converts CDR files from one Ericsson or Nokia format (agreed
from WP2) to the BMP internal format.

Processing

The BMP processing scripts (written in TCL/JAVA languages) will perform:

      o     Perform all checks that FIH used to perform (while converting input
            CDR files to UTX format).

      o     Load the THUFITAB table with a new row for each new CDR file. This
            task was previously performed by the DIH BSCS processes.

      o     Duplicate record check both on CDR level and file level. Replaces
            the DRH BSCS batch process

      o     Consolidation of "long duration calls". Replaces the AIH BSCS batch
            process.

Encoding

The BMP encoder produces output CDR files in BSCS UTX format.

Disk Distribution

UTX output files will be saved to a location which will point directly to the
$WORK_DIR/MP/SWITCH directory on the BSCS server. This directory will be NFS
mounted on the BSCS server. In this way it will be easy to keep track of all CDR
files and it simplifies the backup procedure.

ss. 7 Secrecy

7.1   EuroTel hereby authorizes CGE&Y to make public reference to EuroTel's
      selection of the CGE&Y service line(s) and the nature of the services
      provided. Subject to EuroTel's prior written consent, CGE&Y may publicly
      refer to the solution implemented or to be implemented by CGE&Y and may
      write and publish a high-level profile discussing the reasons supporting
      EuroTel's choice of the CGE&Y solution and the benefits gained by EuroTel.

7.2   EuroTel and CGE&Y agree that any information directly or indirectly
      received from the other party in connection with the above project will be
      treated strictly confidentially. Such confidential treatment requires that
      the information received form the other party (i) will not be disclosed to
      any third party and (ii) will not be used for any purpose other than as
      necessitated by the objective stated in this Agreement. Any use beyond
      this scope, and any disclosure to a third party, requires the prior
      written consent of the disclosing party. However, disclosure to affiliated
      companies or to advisers shall be permitted without such explicit, written
      consent, provided the disclosure is necessitated by the commission and
      further provided any such recipient has first agreed in writing to comply
      with the confidentiality obligations as stipulated by this Agreement. Each
      party will treat information received from the other party with the same
      degree of care as applied to its own confidential or proprietary
      information, and at least with the care afforded by a diligent business
      partner.

7.3   The confidentiality obligation shall not apply with respect to information
      that:

      a)    is known to the recipient without restrictions regarding
            confidentiality prior to receipt form the other party, or

      b)    is publicly available at the time of disclosure, or thereafter
            becomes publicly available other than through a breach of this
            Agreement, or

      c)    is lawfully and without confidentiality obligations obtained from a
            third party.

      Notwithstanding the above, each party shall be entitled to fulfil
      information requests to the extent required by law.

7.4   The confidentiality obligations arising out of this Agreement shall remain
      effective for a term of five (5) years, notwithstanding any earlier
      termination of the Agreement.

                                                      General Terms & Conditions

7.5   EuroTel and CGE&Y agree that no grant of a license or other authorisation
      to use shall be connected to the disclosure of information under this
      Agreement. Neither party shall be entitled to act as an agent or in any
      other capacity for the other party. The establishment of any obligations
      between EuroTel and CGE&Y beyond the scope of this Agreement shall require
      an explicit, written agreement.

7.6   All CGE&Y personnel that have any access to the subscriber names and or
      addresses, electronically or written form, shall sign a separate personal
      confidentiality undertaking.

7.7   CGE&Y shall be liable for it's personnel for any and all misuse of the
      EuroTel subscribers personal data and billing data. In any case, however,
      these data may not be copied, transmitted or transferred in any form from
      the EuroTel location to elsewhere.

ss. 8 Warranty

8.1   CGE&Y warrants that all services provided will be performed professionally
      and in accordance with good workmanship and by personnel with the
      necessary skills. CGE&Y warrants that the system as the result of the
      services rendered by CGE&Y under this Agreement has the functionalities
      stated in the Agreement and that the performance of the system is such as
      can be required considering what has been stated above.

8.2   CGE&Y is, subject to stated limitations, obliged to correct Defects in the
      system caused by CGE&Y and signifying that agreed requirements are not
      met. Rectification will be carried out through correction or, provided
      this does not cause significant inconvenience, by instructions on how to
      circumvent the Defect. The Warranty includes the services required to
      correct Warranty Defects but not costs for materials and equipment. If
      CGE&Y will be compensated for services on a time and material basis, the
      warranty for such services covers CGE&Y's costs to correct defects.

8.3   The Warranty period is six months from acceptance. CGE&Y shall be
      responsible only for Defects notified to CGE&Y without unreasonable delay
      and during the Warranty period.

8.4   Defects covered by the Warranty shall be corrected without unreasonable
      delay. Should a Defect prevent EuroTel from using the system,
      functionalities, products for agreed purposes, the rectification measures
      shall be initiated within 24 hours from the time CGE&Y received
      notification of the Defect. Should CGE&Y not correct a Defect with the
      speed appropriate under the circumstances, EuroTel is allowed to grant
      CGE&Y a final and reasonable extension of time to correct the Defect. If
      the Defect still has not been corrected at the expiry of such an extension
      period, if granted, EuroTel is entitled to a reduction of the purchase
      price for the system, corresponding to a market price for the correction
      of the Defect.

8.5   Should EuroTel report a Defect and it turns out that the reported Defect
      is not one for which CGE&Y is responsible, then EuroTel shall compensate
      CGE&Y on a time and material.

                                                      General Terms & Conditions

8.6   CGE&Y's responsibility does not cover defects which are

      -     discovered or which ought to have been discovered at the acceptance
            test but which have not been notified promptly to CGE&Y,

      -     caused by EuroTel's use of the system, with equipment or accessories
            other than those specified by CGE&Y, in a manner which affects its
            function or by EuroTel's carrying out changes of, or measures with
            the system, not in accordance with CGE&Y's instructions,

      -     due to negligence by EuroTel, its staff or third party or by
            circumstances beyond the control of CGE&Y,

      -     due to the fact that EuroTel has given incorrect or incomplete
            information or choice of test data or has given incorrect or
            incomplete prerequisites for the system.

8.7   Should EuroTel, without the prior consent of CGE&Y, make changes in or
      take measures with the system of such significance that the investigation
      of who is responsible for Defects is considerably impeded, then CGE&Y's
      responsibility according to the Warranty ceases for involved parts of the
      system.

8.8   CGE&Y's responsibilities according to the Warranty are limited to what is
      mentioned in these General Terms and Conditions. Consequently, CGE&Y is
      not obliged to compensate EuroTel for, transport of equipment,
      stand-stills or other damages due to Warranty Defects and EuroTel is not
      entitled to cancel the Agreement due to Warranty Defects.

ss. 9 Liability

9.1   The liability of both parties is restricted to direct damages. Neither of
      the parties shall have any liability for any indirect damages as loss of
      revenue, profit or saving, drop in production, loss of data, third party
      damages or consequential damages. However, this limitation does not apply
      in cases of willful action and gross negligence.

9.2   If there is an agreed delivery time and the Services are delayed,
      penalties will be paid. Such penalties shall be set to an amount per
      completed week that the delay has been going on, equivalent to 0.5 per
      cent of the basis of calculation, but not, however, totalling more than 10
      per cent of the basis of calculation. The basis of calculation shall be
      the remuneration to CGE&Y for the Services initially agreed. If only part
      of the Services are delayed, the basis of calculation shall be the part of
      the contract price or the remuneration, which corresponds to the part of
      the Services which have been delayed. EuroTel is not entitled to any
      remuneration or damages due to late delivery in excess of these penalties.

9.3   The total liability of CGE&Y - when applicable including penalties - is
      limited to an amount, equivalent to 50 per cent of the remuneration to
      CGE&Y for the Services initially agreed. After delivery in accordance with
      ss. 2 CGE&Y is not in any case obliged to repay any remuneration received
      except in accordance with ss.8.4 above.

9.4   CGE&Y is responsible for the performance of work carried out by
      subcontractors as if the work were his own. If CGE&Y has delivered
      hardware or other equipment or system

      or standard software, CGE&Y is not liable in any way or to a any greater
      extent, than what may actually be recovered from the supplier.

9.5   EuroTel's right to damages, penalties or any other remuneration shall be
      forfeited if the claim has not been made in writing without delay and
      within three months from the day of the occurrence of the circumstance,
      which caused the damages. After the expiry of the warranty period CGE&Y
      has no remaining liability, unless CGE&Y has caused damages wilfully or
      through gross negligence. Should a specific warranty for a certain period
      of time not have been agreed, then all liabilities of CGE&Y shall in all
      events cease six months after delivery.

ss. 10 Infringement of Intellectual Property Rights

10.1  CGE&Y guarantees that the use of system, product or documentation
      developed or delivered by CGE&Y in accordance with the Agreement, does not
      infringe the right of any third party to patent, copyright or trademark.
      EuroTel is obliged to give notice immediately to CGE&Y, in case such
      infringement has been alleged or is to be expected.

10.2  CGE&Y shall fully indemnify EuroTel and keep EuroTel indemnified from and
      against all actions, claims, demands, costs, charges and expenses which
      they sustain and which arise from a claim or allegation by a third party
      to the effect that the supply or the modification of the use of system,
      product or documentation developed and delivered by CGE&Y in accordance
      with the Agreement, infringes or caused to be infringed any patent or
      registered design or copyright of a third party or amounts to a breach of
      obligation of non-disclose owed to a third party (and which in either case
      is in existence at the date of Agreement or comes into existence
      thereafter and which, in the latter case, is known or ought reasonably to
      have been known to CGE&Y).

10.3  In the event of any claim being made or action brought against EuroTel
      arising out of the matters referred to in sub-clause 10.2. CGE&Y shall be
      notified promptly thereof, and shall at his own expense conduct all
      negotiations for the settlement of the same and any litigation that may
      result therefrom. EuroTel shall, at the request of CGE&Y, afford all
      available assistance for the purpose of contesting any such claim or
      action and shall be repaid any expenses incurred in so doing.

ss. 11 Force majeure

11.1  A party is not liable for a failure to perform any of his obligations in
      so far as he proves:

      a)    that the failure was caused by circumstances excluding his
            liability; and

      b)    that he could not reasonably be expected to have taken the
            impediment and its effects upon his ability to perform into account
            at the time of the conclusion of the Agreements; and

      c)    that he could not reasonably have avoided or overcome it or at least
            its effects

                                                      General Terms & Conditions

11.2  An impediment within paragraph 11.1 above, may result from events such as
      the following, this enumeration not being exhaustive:

      a)    war, whether declared or not, civil war, riots and revolutions, acts
            of piracy, acts of sabotage;

      b)    natural disasters such as violent storms, cyclones, earthquakes,
            tidal waves, floods, destruction by lightning;

      c)    explosions, fires, destruction of machines, of factories, and of any
            kind of installations;

      d)    boycotts, strikes and lock-outs of all kinds, go-slows, occupation
            of factories and premises, and work stoppages which occur in the
            enterprise of the party seeking relief;

      e)    acts of authority, whether lawful or unlawful, apart from acts for
            which the party seeking relief has assumed the risk by virtue of
            other provisions of the Agreement.

11.3  For the purpose of paragraph 11.1 above, and unless otherwise provided in
      the Agreement, impediment does not include lack of authorisations, of
      licences, of entry or residence permits, or of approvals necessary for the
      performance of the Agreement and to be issued by a public authority of any
      kind whatsoever in the country of the party seeking relief.

11.4  The party seeking relief shall as soon as practicable after the impediment
      and its effects upon his ability to perform became known to him give
      notice to the other party of such impediment and its effects on his
      ability to perform. Notice shall also be given when the ground of relief
      ceases.

11.5  The ground of relief takes effect from the time of the impediment. Failure
      to serve notice makes the failing party liable in damages for loss which
      otherwise could have been avoided

11.6  A ground of relief under this clause relieves the failing party from
      damages, penalties and other contractual sanctions as long as and to the
      extent that the ground subsists.

11.7  Further it postpones the time for performance, for such period as may be
      reasonable, thereby excluding the other party's right, if any, to
      terminate or rescind the Agreement. In determining what is a reasonable
      period, regard shall be had to the failing party's ability to resume
      performance, and the other party's interest in receiving performance
      despite the delay. Pending resumption of performance by the failing party
      the other party may suspend his own performance.

11.8  If the grounds of relief subsist for more than 8 (eight) weeks period,
      either party shall be entitled to terminate the Agreement with written
      notice.

11.9  Each party may retain as is, i.e. with no warranty pursuant to the
      Agreement hereof, what he has received from the performance of the
      Agreement carried out prior to the

1     Introduction

EHPT BMP, developed by EHPT, is an open, multi-service, multi-platform mediation
system that provides you with a flexible, accurate, scalable, and user-friendly
solution for collecting, processing, and distributing service usage data in all
networks.

This open and highly flexible system collects service usage data from many
different networks and different network elements. In an IP network it collects
the data from for example routers, gateways/gatekeepers, web servers and mail
servers. The collected usage data - for Internet, wireline, wireless (including
GPRS) and other network services - is combined into, and flexibly managed by, a
single common billing mediation solution. This solution can be based on one BMP
system or several distributed BMP systems. Besides distributing the usage data
traditionally to billing systems, the BMP solution also processes and
distributes the usage data to other downstream client applications, such as
Fraud and Call Analysis.

                               [GRAPHIC OMITTED]

EHPT BMP:

Make you prepared for unknown business demands

BMP is designed to support your growing business. Maximum flexibility and
scalability enable you to concentrate on expanding your business.

Shortens your Time To Market

The powerful adaptation tools in BMP make it easy to introduce new services and
network elements. And since EHTP BMP isolates your network from your business
applications, you can make changes without disrupting normal operations.

Enables service convergence

BMP collects data from all networks - fixed, mobile, GPRS, Internet and others.
BMP facilitates the transition to the world of IP.

                                                     BMP 4.1 Product Description

Is easy to use

BMP's graphical user interface has been designed in collaboration with service
providers and is extremely easy to use. BMP has help and user documentation
online.

Is proven

BMP has been operational for several years, providing reliable mediation for
more than 80 service providers around the world.

2     System Overview

2.1   Collection, Processing and Distribution

The BMP mediation system has three major features for handling service usage
data collection, processing, and distribution.

                               [GRAPHIC OMITTED]

2.1.1 Collection

BMP collects usage data - automatically and on-line - from multi-service
networks.

2.1.2 Processing

BMP has powerful processing features to prepare the usage data for the
downstream systems by, for example, making sure that the usage data is correct,
adapting the usage data to specific needs and enriching the usage data e.g. with
pre-rating information.

2.1.3 Distribution

BMP can transfer multiple streams of usage data records to different downstream
application systems.

2.1.4 Two BMP Modules

Pricing models will change when service providers enter the new convergent
world.

                                                     BMP 4.1 Product Description

Mediation devices must be able to handle both CDRs and IPDRs. Service providers
in the Internet arena will have different requirements compared to traditional
telecom service providers. The Internet is far more complex, with unlimited
types of applications and services. In the IP world there is no equivalent to
the circuit-switched CDRs, which are necessary to bill for IP services
successfully. The Internet operates in real-time and customer usage must be
collected in the same manner.

BMP therefore has two modules, BMP and BMP IP. BMP is used in a traditional
circuit-switched (Fixed, Mobile including GPRS) environment. BMP IP is used in
an IP (packet-switched) environment. In a convergent solution both modules are
used.

                               [GRAPHIC OMITTED]

2.2   EHPT BMP Definitions

A brief description is given in this section to help the reader understand the
BMP specific (and some other) terms used in this document.

2.2.1 Job

It is necessary to construct a job to manage the flow of data according to a
customer's business rules. A job consists of the collection, processing, and
distribution of usage data.

2.2.2 Group

A BMP job is divided into three functional groups: collection, processing, and
distribution. The job procedures are separated into these groups.

2.2.3 Collection group

A collection group can consist of one or several collection nodes.

                                                     BMP 4.1 Product Description

2.2.4 Processing group

A processing group can consist of one or several processing nodes. It is not
mandatory to have a processing group in a job.

2.2.5 Distribution group

A job can have several distribution groups, each containing one distribution
node.

2.2.6 Nodes

The nodes represent sub-processes and are shown as icons in the User Interface.
The user can choose between different collection, processing, and distribution
nodes to constitute the job.

CDR

Call Detail Record. An accounting record produced by circuit switches (including
GPRS) to track Call Type, Time, Duration, Facilities used, Originator,
Destination, etc. CDRs are used for customer billing, rate determination,
network monitoring and facility capacity planning.

IPDR

Usage Detail Record. An IPDR is the "IP" equivalent of a CDR. The BMP IP module
produces IPDRs.

2.3   BMP Overview

In voice networks Call Detail Records (CDRs) are produced by the Network
Elements. CDRs are collected by the multivendor set of collectors for voice
switches that are available in BMP. CDR files are broken down into individual
CDRs, which can be uniquely processed with the comprehensive set of processing
functionality available. Once the CDRs have been processed and are ready for
distribution, they can be distributed to any desired Post Processing System, for
example a Billing System.

                               [GRAPHIC OMITTED]

2.3.1 Collection

BMP collects usage data - automatically and on-line - from multivendor networks
as well as from other BMP systems. BMP has "off-the-shelf" collectors for
switches from all major vendors.

2.3.2 Processing

BMP has powerful processing features for copying, formatting, merging,
filtering, validating, streaming, modifying, and consolidating usage data. With
the integrated Business Rules Builder, customer-specific processing flows can be
created or changed through a Graphical User Interface (GUI) by combining icons
representing different processing options.

Processing includes an enhanced processing feature, which is an extremely
flexible building block that makes it possible to apply virtually any
user-defined processing in BMP.

2.3.3 Distribution

BMP can transfer multiple streams of individual data records or data files to
different downstream application systems by using a number of different
protocols.

2.3.4 BMP, Base System

The BMP Base System contains the base capabilities of BMP, for example logging,
GUI and scheduling. The scheduler serves as a central control point that, among
other things, starts and maintains jobs and handles the user's requests.

2.3.5 Additional BMP functionality

With the high availability configuration, two BMP systems, each running separate
jobs during normal operation, back each other up in case of a single point of
hardware failure. With the CDR Repair system, CDR files can be viewed and
edited.

2.3.6 Remote Management & Additional Management Applications

BMP web manager application for remote management. BMP provides interfaces for
remote management of one or several BMP systems from a central location.
Management systems based on SNMP and BNSI can also be utilized.

2.4   BMP IP Overview

The old rules of the circuit-switched network do not apply in the IP world. The
Internet is far more complex, with unlimited types of applications and services.
In the IP world there is no equivalent to the circuit-switched CDRs, which are
necessary to bill for IP services successfully. The Internet operates in
real-time and BMP IP collects data in the same manner.

BMP IP enables you to charge for usage by collecting IP network transactions in
real-time, filter away unnecessary information, aggregate information from
different sources and create IPDRs (equivalent to the circuit-switched CDRs). An
IPDR is handled in the same way as a CDR when distributed to BMP and all
functionality that can be used for a CDR can also be applied for an IPDR.

                               [GRAPHIC OMITTED]

For more details on BMP IP please see the BMP IP product description.

                                                     BMP 4.1 Product Description

2.4.1 Collection

BMP IP collects IP transaction data (events) from IP networks - in real-time.

2.4.2 Processing

The BMP IP processing features consist of filtering, aggregation and creation of
IPDRs.

IPDRs can be created either based on time, where the time interval for creating
the IPDR is configurable from sub-seconds to x hours. IPDRs can also be closed
based on the whole log-in period, for e.g. a dial-up connection.

IPDRs can be created according to the IPDR standard, see www.ipdr.com, or any
other customised format.

2.4.3 Distribution

BMP IP can distribute the created IPDRs real time to a dedicated IP billing
system, or to BMP where the IPDRs can be processed utilizing the comprehensive
set of functions available.

2.4.4 BMP IP Base System

The BMP IP Base System contains the base capabilities of BMP, for example
logging, a GUI and security mechanism.

2.4.5 Remote Management & Additional Management Applications

The BMP web manager application can be used for management, i.e. alarms and
status of the BMP IP jobs running. The BMP web manager provides interfaces for
remote management of one or several BMP systems from a central location.

2.5     BMP for convergence

The figure below illustrates an example of a GPRS mediation case when both BMP
and BMP IP are prerequisites for a convergent billing solution. In the example,
a service provider is charging for delivered quality when providing a specific
type of WAP service, for example stock exchange information. The GPRS node
provides information about delivered quality which is then captured by BMP. BMP
IP provides information about who accessed what and for how long. This
information must be consolidated before it can be sent to the billing system.
BMP and BMP IP are the enablers for convergent billing.

In a convergent environment, where different types of networks, both packet and
circuit switched, need to be interfaced for usage data the solution is to use
both BMP and BMP IP. BMP IP is designed to work together with BMP as a
pre-collector. This pre-collector can be seen as an advanced collector which
internally also contains processing. BMP IP deals with the real-time
requirements for capturing the transaction data in an IP network and the
creation of IPDRs. These IPDRs can be further processed by BMP and can be
consolidated with the CDRs from a voice network as well.

Below shows a mediation case for GPRS when both BMP and BMP IP are a
pre-requisite for a flexible convergent billing solution. The example below
shows a service provider charging for Quality delivered when providing a
specific type of WAP service. For example stock information. The GPRS node
provides information about Quality delivered. This is captured by BMP. BMP IP
provides information about who has accessed what, during which time period. This
information has to be consolidated before it can be sent to the billing system.
BMP and BMP IP are the enablers for convergent billing as described.

BMP uses collectors to collect usage data that is to be processed and
distributed to a specific directory, to a downstream client application or to
another BMP system. Data can be collected from different network elements from
different vendors. For circuit-switched networks BMP provides:

      o     FTP Collection

      o     -     Collects from NE's running standard FTP
            -     Collects from Rescission Adjunct Processor using FTP
            -     Collects from Nokias WAP Gateway using NAMP protocol

      o     FTAM Collection

      o     Collects from all major switches using FTAM, such as Lucent 5ESS,
            Ericsson AXE, Siemens EWSD, Alcatel S12 or E10, Nokia DX200 and
            others

      o     Proprietary Collection:
            -     MTP from Ericsson AXE switches

            -     XFER and AFT from Nortel DMS switches
            -     AMATPS for Lucent 5ESS
            -     NEC NEAX

      o     Hot Billing:
            -     DFO from Ericsson AXE switches
            -     DMH (IS-124) from switches utilizing DMH

      o     Disk Collection

      o     InterBMP Collection (collection from other BMP systems)

Hot billing collection means CDR by CDR collection instead of CDR file
collection. BMP supports hot billing collection from AXE using DFO and hot
billing collection from network element utilizing the DMH standard.

The collection function supports duplicated file detection and ensures that
files are not collected more than once.

A WAP Gateway is an enabler of advanced services: it is the access point between
the wireless world and the internet/intranet world. BMP collects mediation data
from Nokias WAP Gateway via FTP.

                               [GRAPHIC OMITTED]

EHPT and its channel partners are constantly adding new collectors to BMP using
the BMP Development Environment. If a desired collector does not exist in BMP, a
new collector specific to a certain network element can easily be developed.

                                                     BMP 4.1 Product Description

BMP offers the possibility to start a script or a binary when a file has been
collected. The script will be executed before the CDR file is transferred to the
processing (or distribution) node.

3.3   Processing

BMP provides a set of standard processing tools as part of its core functions.
BMP supports the following processing functions:

      o     Format translation

      o     Selection

      o     Validation

      o     Unique ID generation

      o     CDR Sequence order validation

      o     Duplicate CDR detection

      o     Time gap detection

      o     Merge

      o     CDR file header/trailer generation and validation

      o     Bursting

For further enhanced processing, the Enhanced Processing Nodes provide features
for:

      o     Assignment

      o     Database look-up

      o     Consolidation

      o     Consolidated usage reports

These features will be further explained in the sections below.

                                                     BMP 4.1 Product Description

3.3.1 Format Translation (Decode/Encode)

The proven format translator is a key architectural component of BMP. The format
translator translates usage data input formats into a format required by the
receiving downstream system. It does this by converting usage data received from
the external network elements to an internal ASN.1 format (decode process) and
then to a user-defined external format (encode process) that matches the
downstream system.

This function can be used to translate all external service-related data from
multi-vendor switches into a common billing format.

BMP provides capabilities to change the order of the CDR fields, to remove
fields and change the data representation. It is also possible to add new
fields.

BMP's processing features require an internal CDR format to be defined using the
ASN.1 format definitions. BMP can translate virtually any type of incoming
format to ASN.1, and convert the internal ASN.1 format to any outgoing format.

3.3.2 Decoding

Files that BMP has collected from network elements or other external systems and
which require processing are converted to BMP's internal ASN.1 format.

If the BMP installation has the Enhanced Format Builder, see chapter 3.6.4. The
user can create customized mapping definitions. These mapping definitions can
then be used to do conversions from various source formats to BMP's internal
format.

3.3.3 Encoding

Files that BMP has processed are converted from the BMP ASN.1 format to an
external format before distribution.

If the BMP installation has the Enhanced Format Builder, see chapter 3.6.4 the
user can create customized mapping definitions. These can then be used for
making conversions from the BMP internal format to various destination formats.

It is possible to define different output formats so that information can be
transferred to multiple destinations. New format definitions may be performed in
runtime without affecting your current revenue flow.

All BMP format conversions conform to the ASN.1 format definitions.

3.3.4 Selection

BMP retrieves CDRs collected from a remote system. The selection feature streams
or filters CDRs to other processing features, or to a file for further
distribution to an external system. The selection feature uses Boolean
operators, comparison operators (equal, not equal, less than, less than or equal
to, greater than, greater than or equal to) and regular expressions to filter
whether field values are included or not included in a defined set of values.

--------------------------------------------------------------------------------
                                                                    Appendix III
                                                     BMP 4.1 Product Description

The selection nodes have two outputs: true or false. Each of the two outputs may
distribute CDRs to many other nodes.

The user can edit existing selection criteria or create new criteria in the
Graphical User Interface (GUI).

3.3.5 Validation

The validation feature checks if particular fields of a CDR are within a defined
logic or range of values in order to filter out those CDRs that do not meet the
validation criteria. A separate error file logs the CDRs that do not meet the
validation criteria. The CDRs can also be forwarded if so desired.

The validation function performs two levels of validation on usage data: format
validation (syntactic level), and business rule validation (logical level).
Business rule validation occurs at configured processing points, and can be used
to decide, for example, if a count or duration value is within "reasonable"
bounds.

Validation rules are composed of many expressions where Boolean operators can be
used to decide whether an expression is true or false. BMP can also store these
expressions in a file, which can be read and interpreted to allow for more
flexibility.

The user can edit existing validation criteria or create new criteria in the
Graphical User Interface (GUI). The parameters that can be checked for
individual fields within a record are:

      o     Value out of range

      o     Unknown value

      o     Field length invalid

      o     Value not included in a predefined set

The user can carry out further handling on the error records that BMP has saved
in a user-defined directory.

BMP allows for the same CDR information to be 'burst' to multiple locations.
This can be useful when more than one downstream PPS is interested in the same
information or a subset of it.

3.3.6 CDR Sequence Order Validation

The CDR sequence order validation feature ensures the sequential processing of
CDRs and that no CDRs in the CDR stream are missing or duplicated. The user can
specify the number of error records ("out of sequence" records) which are
accepted before processing is aborted.

                                                     BMP 4.1 Product Description

BMP removes the error records from the stream and saves them in a
user-configurable directory.

CDR sequence order validation can be applied to CDRs containing a sequence
number field.\

3.3.7 Unique ID Generation

The unique ID generation feature inserts a unique ID in the CDRs for all switch
and service types collected by BMP. A data warehouse, for instance, could
require a unique ID.

3.3.8 Duplicate CDR Detection

The duplicate CDR detection feature ensures that no CDRs are duplicated in the
CDR stream. Duplicate checking can be done both within the same file and between
multiple files. The criteria for considering a CDR to be a duplicate are defined
by the user in the BMP GUI. Duplicate CDRs are stored in an error directory.

3.3.9 Time Gap Detection

The time gap detection feature ensures that there is an acceptable time gap
between two CDRs by comparing the time stamps in the CDRs. The function checks
the minimum and maximum acceptable time gaps between consequential CDRs. The
checking is also done between CDR files, i.e. between the last CDR of one file
and the first CDR of the next. Time Gap Detection can be used to validate that
CDRs are not missing.

3.3.10 CDR File Header/Trailer Generation & Validation

The header/trailer validation feature checks if particular fields of a CDR file
header/trailer are within a defined logic or range of values. Header/trailer
generation makes it possible to generate a new CDR file header and trailer or
modify the contents of an existing one. This is done by assigning values to new
fields in the header/trailer, modifying existing fields or concatenating
existing fields. The enhanced processing node can be used to extract information
from every CDR in a file, which can be used later on in header/trailer
generation.

3.3.11 Merge

Merge is a processing function in BMP that combines several input usage files
into a single, larger output file.

3.3.12 Enhanced Processing - Enhanced Processing Node

Enhanced processing is an extremely flexible building block, which makes it
possible to implement virtually any processing needed.

Enhanced processing in BMP consists of two different nodes, one based on the
JAVA programming language and one on the industry standard TCL script language.
It is possible

                                                     BMP 4.1 Product Description

to apply the same functionality (logic) in both kinds of node.

The Java node has been extended with a number of pre-defined classes and the TCL
node with a number of pre-defined primitives that give BMP the capability for
example to modify field values, access databases (for instance a subscriber
database) or do more complex format conversions. Enhanced processing also
provides capabilities for doing consolidation of partial CDRs and creating
consolidated usage reports by extracting relevant information from the CDRs.

Enhanced processing could be offered as a runtime license, i.e. EHPT or an EHPT
channel partner will do the set-up, or as a development license allowing the
service provider to define their own processing criteria.

3.3.13 Assignment

Assignment makes it possible to modify the contents of a CDR by adding fields,
assigning values to new fields, modifying already existing fields or
concatenating existing fields.

BMP supplies standard library functions (classes in Java and primitives in TCL)
for the most common and straightforward assignment of new values. Arithmetic
operations are also supported.

3.3.14 Database Look-up

The database look-up feature makes it possible to search internal or external
databases. The information gathered could be used for validation purposes or to
assign new information to existing fields in a CDR. TCL script primitives or
JAVA classes are available for the more common types of database searches.

BMP can retrieve values from the database and use return values to assign these
to new fields in the CDR.

                               [GRAPHIC OMITTED]

3.3.15 Consolidation

                                                     BMP 4.1 Product Description

The consolidation function consolidates partial CDRs. It merges the CDRs that
belong to the same chargeable call into one CDR, typically long duration calls
or calls that go on during the "midnight shift", and sends it to the downstream
system. Consolidation is also a key functionality for handling both IP IPDRs and
GPRS CDRs in a GSM network, since information from many sources needs to be
consolidated into one chargeable record.

A selection node identifies the partial CDRs and sends them to the consolidation
node. The consolidation node keeps them waiting until it finds the matching
CDRs, and merges them into one.

The user can define criteria to identify the CDRs that belong to the same
chargeable call. The user can also define the criteria for how the different
fields should be merged before dispatching the consolidated CDR from the
consolidation function, for example to a billing system. It is also possible to
consolidate CDRs from different network elements.

3.3.16 Consolidated Usage Reports

By extracting information from CDRs passing a report (enhanced processing) node,
data can be extracted and stored in pre-defined tables in the BMP database. The
stored data can then be extracted and presented in customer-unique reports by
using for instance Oracle reports or an ODBC connection to Microsoft Excel or
Microsoft Access.

Examples of reports that could be created using the data in the pre-defined
table structure are:

      o     Total number of call minutes (or calls) per day per switch

      o     Total number of call minutes (or calls) per day per incoming and/or
            outgoing trunk/route

      o     Total number of call-minutes (or calls) per hour per switch etc

      o     Data volumes per hour per router (when receiving IPDRs from BMP IP)

3.3.17 Error handling in the processing nodes

Behavior when decoding or processing errors occurs is configurable. The
error-handling feature provides three options:

      o     -Abort on Max Fail. The processing node will abort when a user
            defined maximum number of erroneous CDRs has been reached. BMP
            writes all erroneous CDRs to an error directory until the maximum
            number is reached.

      o     Abort on First File. BMP writes the incorrect file to an error
            directory and the processing is stopped.

      o     Continue with next file. BMP writes the file with the erroneous CDRs
            to an error directory and automatically continues with the next
            file.

                                                     BMP 4.1 Product Description

The decoding node can be set up to decode as much as possible of any faulty CDR
file, hence all CDRs in a file that can be decoded will be decoded and passed to
the next processing node. The remaining CDRs will be stored in a file in an
error directory.

3.3.18 Distribution

The distribution function provides a flexible transfer of usage data files or
individual records to downstream applications, such as fraud and call behavior
analysis systems, billing and rating systems, other BMP systems, or to disks.
BMP supports:

      o     File transfer over FTP

      o     File transfer over FTAM

      o     Transfer of files or individual records over TCP/IP

      o     File transfer to disk, (local or NFS mounted)

      o     Transfer of files to another BMP system, using an InterBMP file and
            message transfer function

                               [GRAPHIC OMITTED]

3.3.19 Distribution File Name Templates

The distribution file name templates feature allows the user to set the names of
the files to be distributed. The feature provides many name components to choose
from, such as qualifier, source, source file, job, separator between the name
parts, and type of data.

3.3.20 Post Processing Notification

When BMP has processed the CDRs and they have been distributed, it is sometimes
necessary to alert a post-processing system, such as a billing system. BMP
offers the possibility to start a script when a file has been closed and
distributed. The user defines the script and can for example choose to send a
mail to inform the post-processing system that the file is ready.

                                                     BMP 4.1 Product Description

3.3.21 Base System

BMP base system includes the basic capabilities of BMP. These are described
below under the following headings:

      o     Scheduling

      o     Business Rules Builder

      o     Management

      o     On-line documentation

      o     User access and security

      o     Scalability

      o     Additional management application & Remote management

3.3.22 Scheduling

BMP provides an extensive scheduler, which allows the user to configure and
specify when BMP will perform collection, processing and distribution. The
scheduler, which is an internal subsystem of BMP, serves as a central control
point that is responsible for starting and maintaining jobs, handling requests
from the GUI and so on.

There are three types of scheduling that can be applied to the groups within a
BMP job: periodic, file close and external request. Periodic scheduling and
external request can be used for all collection, processing and distribution
groups, while file close scheduling can be used for processing and distribution
groups only.

3.3.23 Periodic Scheduling

There are three different types of periodic scheduling trigger: weekly, daily or
at an absolute time. BMP can combine multiple schedule configurations to define
a running schedule that specifies when a group within a job will be triggered.
When the time configured for the group is reached, the BMP system will start the
group.

Weekly and daily scheduling can have periodic repeat schedules according to the
setting of a repeat interval parameter. Both schedules can have two parameters,
an activation time and a repeat interval. The activation time specifies when the
schedule will become active. For a weekly schedule, this is a day of the week
plus a time of the day. For a daily schedule, it is simply a time during the
day. The repeat interval specifies the interval between each schedule trigger.

Absolute schedules have an absolute activation time, but no repeat interval
associated with them.

3.3.24 File Close Scheduling

                                                     BMP 4.1 Product Description

There are two types of file close scheduling; one is based on the number of
files queued up from the previous group in the job chain, the other on the
number of bytes queued up from the previous group in the job chain.

Processing and distribution groups that are configured for file close scheduling
will be triggered immediately when the specified number of files or bytes is
available.

3.3.25 External Request

Scheduling using an external request can be applied to all groups in a job, but
the procedure for using this type of scheduling is dependent on the operation of
an operator-created application.

3.3.26 Business Rules Builder

With BMP's integrated Business Rules Builder, the processing flows are created
according to the customer's specific business rules. The business rules are
created or changed easily through BMP's comprehensive GUI, by combining icons
representing the different processing, collection and distributing nodes.

3.3.27 Management

BMP provides extensive functions for operating, administrating and maintaining
the BMP system, including:

      o     Monitoring

      o     Logging

      o     Data management

      o     Exception handling, recovery and back-up

3.3.28 Monitoring

The user can access a BMP monitoring window that displays information about
active jobs. The user can specify the type of data to be displayed for the jobs.
Information can be shown about the following:

      o     Job name

      o     Group type

      o     Job and group identifiers

      o     The data file currently being processed by the group

      o     The source name for the collection group

      o     The destination name for the distribution group

      o     The date and time of the monitored activity

The monitor data is continuously updated while a job is running, and shows the
transient information as the jobs are being executed.

3.3.29 Report Mechanism, Logging

The BMP system provides four logs, which hold data about jobs, user actions,
events and errors. These are:

      o     Audit log

      o     Event log

      o     User log

      o     Error log

A BMP cleanup function periodically clears data from the user and event logs.
The data in the audit and error logs are not affected by the cleanup. Only the
BMP system administrator can remove the data.

                               [GRAPHIC OMITTED]

3.3.30 Audit Log

The audit log window displays audit information about jobs. The information
displayed is dependent on the log level set for the job, which is
user-configurable. For a specific job, the audit log can provide information
about:

      o     The job name

      o     The file name

      o     The number of CDRs processed by the processing nodes

      o     The size of a file in bytes

      o     The source of the collected file(s)

      o     The name of the collection group

      o     The icon number of the processing feature

      o     The date and time of the audited activity

The number of CDRs processed by the processing node are displayed as:

      o     Incoming number of CDRs

      o     Outgoing number of CDRs

      o     Merged number of CDRs

      o     Saved number of CDRs

      o     Deleted number of CDRs

      o     Modified CDRs

BMP uses the audit log to maintain historical information about the processing
of received CDR files.

3.3.31 Event Log

The event log displays information about events and for jobs. The event log
displays:

      o     The type of event that BMP logged, for example job started, job
            stopped

      o     The job status, for example success or fail

      o     The name of the job as defined in a job definition window

      o     The BMP user associated with the event

      o     The date and time of the logged event

      o     Additional information concerning the event

BMP periodically clears the event log data after a configurable interval to
prevent the database from becoming full.

3.3.32 User Log

The user log displays information about actions and the user entities related to
these actions for a selected BMP user. The user log displays:

      o     The BMP user associated with the entry

      o     The selected maintenance area function manipulated

      o     Selected actions, for example delete, insert, log in, and logout

      o     The date and time for the log entry

      o     Information from the system about the logged entries

                                                     BMP 4.1 Product Description

The user log shows the results of a user's interaction with the system. The type
and amount of information that BMP display is configurable. BMP periodically
clears the event log data after a configurable interval to prevent the database
from becoming full.

3.3.33 Error Log

The error log displays information about warning situations, error situations
and critical situations that have occurred in the system.

3.3.34 Data Management

The user can configure how often BMP should automatically remove files that have
been processed and distributed. BMP also surveys the database and alerts the
user when it is running out of disk space.

3.3.35 Exception Handling, Recovery and Back up

BMP stores all information about a job in its database. At a restart, BMP starts
from the last unprocessed file. For example, if a job consists of ten files and
an error occurs at file three, BMP starts with file four at start-up. BMP also
features on-line back up using internal BMP features.

3.3.36 On-line Documentation

User documentation is provided on-line in HTML format. The BMP User Guide,
Procedure manual and System Administrators guide can be viewed on-line, with
hyperlinks to all chapters and sub-chapters, in a Netscape or Microsoft Explorer
browser.

                               [GRAPHIC OMITTED]

3.3.37 User Access and Security

There are two levels of user connection and authentication on BMP systems:

      o     The end user has to log in to the Unix system and provide a
            password. The work environment can be loaded without any possibility
            of running direct command lines

      o     The end user has to provide a second password when connecting to
            BMP\

BMP verifies the functions that are available to the user in the log on
procedure. After log-on, BMP connects with the system, and performs an authority
check. Each user has a profile (called user) which the BMP database
administrator sets up in the BMP system. This profile defines the user's
privileges for each BMP function.

BMP allows for two classes of users - the system administrator and the user.

                                                     BMP 4.1 Product Description

3.3.38 System Administrator

The system administrator manages the overall BMP network, systems and
applications. The system administrator grants user privileges according to user
level activity. The system administrator is the only one with authority to
maintain BMP user accounts and privileges and maintain BMP licenses.

The system administrator only allows the following actions:

      o     Maintain users, and their access rights

      o     Maintain the BMP authorization key. With this key, the user unlocks
            the different features in BMP

3.3.39 User

The user performs BMP node-specific operations. BMP traces user actions into a
user log. From this log, the user can at any time identify the user responsible
for each action. The user can change his or her password, if the old password
can be given.

Multiple levels of clearances provide high security. For example, it is possible
to enable/disable the following actions for each user:

      o     View

      o     Update/insert

      o     Delete

3.3.40 Scalability

BMP is scalable both in capacity and functionality.

Additional functionality can easily be introduced with no, or only minor,
changes to an existing BMP solution.

A single server BMP system is capable of handling a substantial volume of CDR
data and if this should not be enough, BMP can be installed in a distributed
solution containing two or more BMP systems. The system is still, however,
manageable from a central location using industry standard management tools and
specific BMP applications (see Remote Management/Additional Management
Applications).

EHPT recommends separate dimensioning for each implementation case. Factors to
consider when dimensioning a solution include: peak throughput, number of days
of on-line data storage needed, locations of servers at IT center or network
elements building, and the possible need for a high level of availability.

3.4 BMP, Additional Functionality

3.4.1 Web Manager

The Web Manager allows the user to monitor and supervise several EHPT BMP,
Initiator and BMP/Initiator IP Systems at a time from a Web browser (Netscape
Navigator or Communicator).

From each managed system the user can view:

      o     the status of the system

      o     system statistics

      o     data throughput

      o     the status of individual jobs

      o     the error log.

The Web Manager presents information on two different levels: 1) a systems
overview, with information for all supervised systems and 2) a system view, with
information for one selected supervised system.

In the system overview (1) the following information is displayed:

      o     A table with the system state, number of jobs, number of running
            jobs, and data throughput.

      o     A common alarm list for all systems, showing the most recent alarms.
            The alarm list can be filtered by severity.

From the system view as 2) the following information is displayed:

      o     All jobs on this system with current state and descriptions. The
            jobs can be started and stopped.

      o     The alarm list for this specific system. The alarm list can be
            filtered by severity.

The Web Manager consists of three parts: proxy, server and client. The proxy
runs on the same server as the supervised system and handles all connections
with the supervised system. The Server handles the connections between proxy and
client. The user interface runs on the client.

3.4.2 BNSI Agent

Remote alarm surveillance from EHPT SYNERGIZER can be done using the BNSI
functionality within BMP. Alarms received from an external NE will normally be
followed by an alarm clear message. The alarm can therefore be activated or
cleared in the NE. Alarms that have no clear messages are classified as
"events". If an alarm is classified as an event no message will automatically be
sent to notify that the fault has been corrected. The BNSI Agent has the
following functionality:

--------------------------------------------------------------------------------
                                                                    Appendix III
                                                     BMP 4.1 Product Description

      o     Alarm Message Forwarding
            (BNSI Agent reads the BMP log file and translates errors into the
            BMSI alarm structure).

      o     Alarm Filtering
            (based on severity and whether the alarm should be sent or not).

      o     Heartbeat transmission
            (The BNSI Agent can send a heartbeat if no alarms have been
            forwarded within a set time limit).

3.4.3 SNMP Agent

An SNMP Agent forwards BMP errors as traps to a SNMP Manager enabling BMP to be
supervised centrally. The operator will be alerted when an abnormal event occurs
and can access information in order to take a decision on what action to take.
The functionality included in the SNMP agent is:

      o     Alarm Message Forwarding
            (The SNMP Agent reads the BMP log file and translates alarms into
            the SNMP alarm structure)

      o     Alarm Filtering
            (At three levels: Error, Disaster, Warning)

      o     Configurable Polling Time
            ( The frequency (in seconds) at which the Agent polls the BMP log
            file)

      o     Configurable Destination IP Address
            (The destination IP of the Receiving SNMP Manager can be configured
            and is read by the agent at start up)

      o     Configurable SNMP Trap Type
            (i.e. SNMPV1 or SNMPV2 which is read at start up)

      o     'The SNMP Agent does not include a MIB.

3.4.4 Job Distribution

With the script-based job distribution functionality, BMP jobs can be extracted
from one BMP system, including all set-up information for that particular job,
and transferred to another BMP system, for instance BMP jobs from a test
environment into a production environment.

3.4.5 CDR Repair System

The BMP CDR Repair System (CDR RS) is a tool for examining, editing and
correcting erroneous CDR files to be able to reprocess them. It has an easy to
use GUI, which gives access to the following functionality:

o     Encode and decode CDR files

The CDR RS encodes and decodes all ASN.1 formats that BMP supports. When opening
a file the user chooses the file format and the external format. The CDR RS then
displays the internal formats that can be mapped to the selected external
format. All formats are fetched from the BMP dB and new formats must therefore
be added with BMP Format Builder before the CDR RS can use them.

When encoding a file from the internal ASN.1 format the previous external file
format will be utilised. However, the file can also be given a new name and/or
format, leaving the original file untouched.

o     Editing Data

Decoded data is displayed in a spreadsheet. Each column represents a CDR field
and each row a CDR number. New data can be typed directly into a CDR field or a
find/replace function can be utilised to enter correct data into the field. If
incorrect data has been entered or a field or a field is missing data, the field
will be marked and the user must re-enter correct data.

o     Filtering data

The CDRs displayed in the spreadsheet can be filtered. A filer only applies to a
single column. Multiple filters can be added to each column.

The system can be used as a tool for basic creation of CDR data for test
purposes.

3.4.6 High Availability

To attain a high level of availability, the BMP system can provide duplicated
data links toward the network elements. To prevent any loss of data, BMP uses
mirrored disks for secure storage of all data.

To further increase availability, BMP can be configured as a high availability
system where dual computer systems back each other up. During normal run-time,
the two BMP systems work completely independently of each other and run separate
jobs, but if a single hardware failure occurs the BMP package on that particular
hardware will migrate over to the other machine. The high availability function
therefore ensures the flow of BMP operations. The hardware investment is also
fully utilized, since both servers are running during normal operation. The
configuration shown below is not the complete hardware specification, but merely
an outline of the main parts.

3.5 Tools - Implementation and Adaptation

BMP provides very competitive tools for implementation and adaptation. These
tools, and a broad range of services ensure you can quickly deploy (and change)
a system adapted to your specific needs. The following tools and features exist:
Business Rules Builder, Format Builder, Enhanced Processing Node, Script
Invocations and a complete BMP Development Environment (BMP DevKit).

3.5.1 Business Rules Builder

With Business Rules Builder, processing flows can be created according to your
specific business rules. The business rules are created and changed easily
through BMP's comprehensive GUI - by combining icons representing the different
processing, collection and distributing nodes.

3.5.2 Script Invocations

There are a number of possibilities for adapting collection and distribution to
the environment that BMP is working in by invoking customer-unique scripts:

      o     Post Collection Notification, which offers the possibility to run a
            script after a file has been collected

      o     PPS Notification script, which offers the possibility to run a
            script when a file has been distributed

      o     Selection and Validation expressions can be built using the BMP GUI,
            but can also be built as separate scripts.

                                                     BMP 4.1 Product Description

3.5.3 Enhanced Processing Node, Development License

Enhanced processing is an extremely useful tool, which enables you to virtually
implement any processing needed. Enhanced processing in BMP consists of two
different nodes; one based on the JAVA programming language and the other on the
industry standard TCL script language. It is possible to apply the same
functionality (logic) in both nodes.

The enhanced processing development license gives service providers the right to
develop their own processing schemes using the enhanced processing node.

The node can also be used as a runtime node when EHPT or EHPT channel partners
are implementing the processing to be applied.

3.5.4 Enhanced Format Builder

The Enhanced Format Builder (EFB) is a graphical tool designed to facilitate the
production of ASN.1 format definition files. EFB is used to build, edit and
verify the format definition files that define the structure of incoming,
internal and outgoing data in BMP.

3.5.5 BMP Development Environment (EHPT BMP DevKit)

With the proven BMP development environment, introducing completely new
collectors is easy. It is also possible to introduce completely new processing
or distribution features and to customise BMP to customer-specific needs.

                                             Enclosure I - Sub-License Agreement

            "CGEY")

EuroTel Bratislava a.s., referred to below as EuroTel and Cap Gemini Ernst &
Young Slovensko s.r.o referred to below as CGE&Y have today entered into the
following agreement regarding BMP software licenses.

2 Contract documents

This Sub-license Agreement consists of the following two parts:

o     This Sub-License Agreement

o     BMP 4.1 Product Description (Appendix I)

The parties will sign a separate agreement, Agreement Project Work, covering
implementation services for the Software.

3 Definitions

Agreement    means this Sub-License Agreement, agreed and signed between the
             Parties including Appendices and enclosures.

EHPT         means the company that has an office at Johan Wellinsgatan 6 in
             Gotenburg, Sweden. EHPT has developed the Software and is
             delivering the Software to CGE&Y as a sub-supplier
Software     means the EHPT BMP 4.1 Mediation Device Software, further defined
             in ss.3 of this Agreement and in Enclosure 1
System       means all Hardware and Software
RTU          means right to use
RTC          means right to connect
Order Date   is defined as the date of signature of this Agreement
BMP          means a multi-service Mediation Device system from EHPT that
             provides Telecom Operators, such as EuroTel, with a solution to
             collect, process and distribute service usage data in all networks
VPN          means Virtual Private Network
Subscriber   A basic rule (for fixed and mobile subscribers): A subscriber is
             defined to be the number of telephone numbers from active users
             that generate CDR's managed by the Operator. Thus in the
             residential case, there may be one or two telephones for each
             residential user. A large corporate subscriber though (even though
             they are one corporate subscriber) will actually have many
             telephone numbers in their VPN and it is these
             subscribers/telephone numbers that should be used in the RTC
             calculation.

the right to settle such claim on behalf of EuroTel on any terms CGE&Y deems
desirable.

1 Introduction

EHPT BMP, developed by EHPT, is an open, multi-service, multi-platform mediation
system that provides you with a flexible, accurate, scalable, and user-friendly
solution for collecting, processing, and distributing service usage data in all
networks.

This open and highly flexible system collects service usage data from many
different networks and different network elements. In an IP network it collects
the data from for example routers, gateways/gatekeepers, web servers and mail
servers. The collected usage data - for Internet, wireline, wireless (including
GPRS) and other network services - is combined into, and flexibly managed by, a
single common billing mediation solution. This solution can be based on one BMP
system or several distributed BMP systems. Besides distributing the usage data
traditionally to billing systems, the BMP solution also processes and
distributes the usage data to other downstream client applications, such as
Fraud and Call Analysis.

                                [GRAPHIC OMITTED]

EHPT BMP:

Make you prepared for unknown business demands

BMP is designed to support your growing business. Maximum flexibility and
scalability enable you to concentrate on expanding your business.

Shortens your Time To Market

The powerful adaptation tools in BMP make it easy to introduce new services and
network elements. And since EHTP BMP isolates your network from your business
applications, you can make changes without disrupting normal operations.

Enables service convergence

BMP collects data from all networks - fixed, mobile, GPRS, Internet and others.
BMP facilitates the transition to the world of IP.

BMP has been operational for several years, providing reliable mediation for
more than 80 service providers around the world.

2 System Overview

2.1 Collection, Processing and Distribution

The BMP mediation system has three major features for handling service usage
data collection, processing, and distribution.

                                [GRAPHIC OMITTED]

                         Figure 2. Overview of EHPT BMP

2.1.1 Collection

BMP collects usage data - automatically and on-line - from multi-service
networks.

2.1.2 Processing

BMP has powerful processing features to prepare the usage data for the
downstream systems by, for example, making sure that the usage data is correct,
adapting the usage data to specific needs and enriching the usage data e.g. with
pre-rating information.

2.1.3 Distribution

BMP can transfer multiple streams of usage data records to different downstream
application systems.

2.1.4 Two BMP Modules

Pricing models will change when service providers enter the new convergent
world. Mediation devices must be able to handle both CDRs and IPDRs. Service
providers in the Internet arena will have different requirements compared to
traditional telecom service providers.

The Internet is far more complex, with unlimited types of applications and
services. In the IP world there is no equivalent to the circuit-switched CDRs,
which are necessary to bill for IP services successfully. The Internet operates
in real-time and customer usage must be collected in the same manner.

BMP therefore has two modules, BMP and BMP IP. BMP is used in a traditional
circuit-switched (Fixed, Mobile including GPRS) environment. BMP IP is used in
an IP (packet-switched) environment. In a convergent solution both modules are
used.

2.2 EHPT BMP Definitions

A brief description is given in this section to help the reader understand the
BMP specific (and some other) terms used in this document.

2.2.1 Job

It is necessary to construct a job to manage the flow of data according to a
customer's business rules. A job consists of the collection, processing, and
distribution of usage data.

2.2.2 Group

A BMP job is divided into three functional groups: collection, processing, and
distribution. The job procedures are separated into these groups.

2.2.3 Collection group

A collection group can consist of one or several collection nodes.

2.2.4 Processing group

A processing group can consist of one or several processing nodes. It is not
mandatory to

have a processing group in a job.

2.2.5 Distribution group

A job can have several distribution groups, each containing one distribution
node.

2.2.6 Nodes

The nodes represent sub-processes and are shown as icons in the User Interface.
The user can choose between different collection, processing, and distribution
nodes to constitute the job.

CDR

Call Detail Record. An accounting record produced by circuit switches (including
GPRS) to track Call Type, Time, Duration, Facilities used, Originator,
Destination, etc. CDRs are used for customer billing, rate determination,
network monitoring and facility capacity planning.

IPDR

Usage Detail Record. An IPDR is the "IP" equivalent of a CDR. The BMP IP module
produces IPDRs.

2.3 BMP Overview

In voice networks Call Detail Records (CDRs) are produced by the Network
Elements. CDRs are collected by the multivendor set of collectors for voice
switches that are available in BMP. CDR files are broken down into individual
CDRs, which can be uniquely processed with the comprehensive set of processing
functionality available. Once the CDRs have been processed and are ready for
distribution, they can be distributed to any desired Post Processing System, for
example a Billing System.

2.3.1 Collection

BMP collects usage data - automatically and on-line - from multivendor networks
as well as from other BMP systems. BMP has "off-the-shelf" collectors for
switches from all major vendors.

2.3.2 Processing

BMP has powerful processing features for copying, formatting, merging,
filtering, validating, streaming, modifying, and consolidating usage data. With
the integrated Business Rules Builder, customer-specific processing flows can be
created or changed through a Graphical User Interface (GUI) by combining icons
representing different processing options.

Processing includes an enhanced processing feature, which is an extremely
flexible building block that makes it possible to apply virtually any
user-defined processing in BMP.

2.3.3 Distribution

BMP can transfer multiple streams of individual data records or data files to
different downstream application systems by using a number of different
protocols.

2.3.4 BMP, Base System

The BMP Base System contains the base capabilities of BMP, for example logging,
GUI and scheduling. The scheduler serves as a central control point that, among
other things, starts and maintains jobs and handles the user's requests.

2.3.5 Additional BMP functionality

With the high availability configuration, two BMP systems, each running separate
jobs during normal operation, back each other up in case of a single point of
hardware failure.

With the CDR Repair system, CDR files can be viewed and edited.

2.3.6 Remote Management & Additional Management Applications

BMP web manager application for remote management. BMP provides interfaces for
remote management of one or several BMP systems from a central location.
Management systems based on SNMP and BNSI can also be utilized.

2.4 BMP IP Overview

The old rules of the circuit-switched network do not apply in the IP world. The
Internet is far more complex, with unlimited types of applications and services.
In the IP world there is no

equivalent to the circuit-switched CDRs, which are necessary to bill for IP
services successfully. The Internet operates in real-time and BMP IP collects
data in the same manner.

BMP IP enables you to charge for usage by collecting IP network transactions in
real-time, filter away unnecessary information, aggregate information from
different sources and create IPDRs (equivalent to the circuit-switched CDRs). An
IPDR is handled in the same way as a CDR when distributed to BMP and all
functionality that can be used for a CDR can also be applied for an IPDR.

                                [GRAPHIC OMITTED]

                       Figure 5. Overview of BMP IP system

For more details on BMP IP please see the BMP IP product description.

2.4.1 Collection

BMP IP collects IP transaction data (events) from IP networks -- in real-time.

2.4.2 Processing

The BMP IP processing features consist of filtering, aggregation and creation of
IPDRs. IPDRs can be created either based on time, where the time interval for
creating the IPDR is configurable from sub-seconds to x hours. IPDRs can also be
closed based on the whole log-in period, for e.g. a dial-up connection.

IPDRs can be created according to the IPDR standard, see www.ipdr.com, or any
other customised format.

2.4.3 Distribution

BMP IP can distribute the created IPDRs real time to a dedicated IP billing
system, or to BMP where the IPDRs can be processed utilizing the comprehensive
set of functions available.

2.4.4 BMP IP Base System

The BMP IP Base System contains the base capabilities of BMP, for example
logging, a GUI and security mechanism.

2.4.5 Remote Management & Additional Management Applications

The BMP web manager application can be used for management, i.e. alarms and
status of the BMP IP jobs running. The BMP web manager provides interfaces for
remote management of one or several BMP systems from a central location.

2.5 BMP for convergence

The figure below illustrates an example of a GPRS mediation case when both BMP
and BMP IP are prerequisites for a convergent billing solution. In the example,
a service provider is charging for delivered quality when providing a specific
type of WAP service, for example stock exchange information. The GPRS node
provides information about delivered quality which is then captured by BMP. BMP
IP provides information about who accessed what and for how long. This
information must be consolidated before it can be sent to the billing system.
BMP and BMP IP are the enablers for convergent billing.

In a convergent environment, where different types of networks, both packet and
circuit switched, need to be interfaced for usage data the solution is to use
both BMP and BMP IP.

BMP IP is designed to work together with BMP as a pre-collector. This
pre-collector can be seen as an advanced collector which internally also
contains processing. BMP IP deals with the real-time requirements for capturing
the transaction data in an IP network and the creation of IPDRs. These IPDRs can
be further processed by BMP and can be consolidated with the CDRs from a voice
network as well.

Below shows a mediation case for GPRS when both BMP and BMP IP are a
pre-requisite for a flexible convergent billing solution. The example below
shows a service provider charging for Quality delivered when providing a
specific type of WAP service. For example stock information. The GPRS node
provides information about Quality delivered. This is captured by BMP. BMP IP
provides information about who has accessed what, during which time period. This
information has to be consolidated before it can be sent to the billing system.
BMP and BMP IP are the enablers for convergent billing as described.

3.1.2 Maintenance

The maintenance menus allow the user to perform maintenance of parameters for
the collection, processing, and distribution features of the BMP system, such
as:

      o     Network elements, external BMP systems, and Post-Processing Systems
            (downstream systems)

      o     Criteria for format translation, CDR sequence number validation,
            selection, validation, etc

      o     Privileges for BMP system users

3.1.3 Job

The job menu allows the user to construct a BMP job by selecting icons from a
palette, placing them in a job control window, and connecting them to perform
the required functions for the collection, processing, and distribution of CDRs.

Multiple job handling allows several jobs to be controlled at the same time.

In the job monitor window, the user can monitor information about the jobs he or
she is interested in.

3.1.4 Inspect

The Inspect menu allows the user to view or configure the BMP logs.

3.1.5 Help

The help menu displays a window that provides information to guide the user in
the operation of the BMP GUI.

3.2 Collection

BMP uses collectors to collect usage data that is to be processed and
distributed to a specific directory, to a downstream client application or to
another BMP system.

Data can be collected from different network elements from different vendors.

For circuit-switched networks BMP provides:

      o     FTP Collection

      o     - Collects from NE's running standard FTP
            - Collects from Rescission Adjunct Processor using FTP
            - Collects from Nokias WAP Gateway using NAMP protocol

      o     FTAM Collection

      o     Collects from all major switches using FTAM, such as Lucent 5ESS,
            Ericsson AXE, Siemens EWSD, Alcatel S12 or E10, Nokia DX200 and
            others

      o     Proprietary Collection:

            - MTP from Ericsson AXE switches
            - XFER and AFT from Nortel DMS switches
            - AMATPS for Lucent 5ESS
            - NEC NEAX

      o     Hot Billing:

            - DFO from Ericsson AXE switches
            - DMH (IS-124) from switches utilizing DMH

      o     Disk Collection

      o     InterBMP Collection (collection from other BMP systems)

Hot billing collection means CDR by CDR collection instead of CDR file
collection. BMP supports hot billing collection from AXE using DFO and hot
billing collection from network element utilizing the DMH standard.

The collection function supports duplicated file detection and ensures that
files are not collected more than once.

A WAP Gateway is an enabler of advanced services: it is the access point between
the wireless world and the internet/intranet world. BMP collects mediation data
from Nokias WAP Gateway via FTP.

                                [GRAPHIC OMITTED]

                      Figure 9. Circuit-switched Collection

EHPT and its channel partners are constantly adding new collectors to BMP using
the BMP Development Environment. If a desired collector does not exist in BMP, a
new collector specific to a certain network element can easily be developed.

3.2.1 Post Collection Notification

BMP offers the possibility to start a script or a binary when a file has been
collected. The script will be executed before the CDR file is transferred to the
processing (or distribution) node.

3.3 Processing

BMP provides a set of standard processing tools as part of its core functions.
BMP supports the following processing functions:

      o     Format translation

      o     Selection

      o     Validation

      o     Unique ID generation

      o     CDR Sequence order validation

      o     Duplicate CDR detection

      o     Time gap detection

      o     Merge

      o     CDR file header/trailer generation and validation

      o     Bursting

For further enhanced processing, the Enhanced Processing Nodes provide features
for:

      o     Assignment

      o     Database look-up

      o     Consolidation

      o     Consolidated usage reports

These features will be further explained in the sections below.

                                [GRAPHIC OMITTED]

3.3.1 Format Translation (Decode/Encode)

The proven format translator is a key architectural component of BMP. The format
translator translates usage data input formats into a format required by the
receiving downstream system. It does this by converting usage data received from
the external network elements to an internal ASN.1 format (decode process) and
then to a user-defined external format (encode process) that matches the
downstream system.

This function can be used to translate all external service-related data from
multi-vendor switches into a common billing format.

BMP provides capabilities to change the order of the CDR fields, to remove
fields and change the data representation. It is also possible to add new
fields.

BMP's processing features require an internal CDR format to be defined using the
ASN.1 format definitions. BMP can translate virtually any type of incoming
format to ASN.1, and convert the internal ASN.1 format to any outgoing format.

3.3.2 Decoding

Files that BMP has collected from network elements or other external systems and
which require processing are converted to BMP's internal ASN.1 format.

If the BMP installation has the Enhanced Format Builder, see chapter 3.6.4. The
user can create customized mapping definitions. These mapping definitions can
then be used to do conversions from various source formats to BMP's internal
format.

3.3.3 Encoding

Files that BMP has processed are converted from the BMP ASN.1 format to an
external format before distribution.

If the BMP installation has the Enhanced Format Builder, see chapter 3.6.4 the
user can create customized mapping definitions. These can then be used for
making conversions from the BMP internal format to various destination formats.

It is possible to define different output formats so that information can be
transferred to multiple destinations. New format definitions may be performed in
runtime without affecting your current revenue flow.

All BMP format conversions conform to the ASN.1 format definitions.

3.3.4 Selection

BMP retrieves CDRs collected from a remote system. The selection feature streams
or filters

--------------------------------------------------------------------------------

                                                                      Appendix I

CDRs to other processing features, or to a file for further distribution to an
external system. The selection feature uses Boolean operators, comparison
(equal, not equal, less than, less than or equal to, greater than, greater than
or equal to) operators and regular expressions to filter whether field values
are included or not included in a defined set of values.

The selection nodes have two outputs: true or false. Each of the two outputs may
distribute CDRs to many other nodes.

The user can edit existing selection criteria or create new criteria in the
Graphical User Interface (GUI).

3.3.5 Validation

The validation feature checks if particular fields of a CDR are within a defined
logic or range of values in order to filter out those CDRs that do not meet the
validation criteria. A separate error file logs the CDRs that do not meet the
validation criteria. The CDRs can also be forwarded if so desired.

The validation function performs two levels of validation on usage data: format
validation (syntactic level), and business rule validation (logical level).
Business rule validation occurs at configured processing points, and can be used
to decide, for example, if a count or duration value is within "reasonable"
bounds.

Validation rules are composed of many expressions where Boolean operators can be
used to decide whether an expression is true or false. BMP can also store these
expressions in a file, which can be read and interpreted to allow for more
flexibility.

The user can edit existing validation criteria or create new criteria in the
Graphical User Interface (GUI). The parameters that can be checked for
individual fields within a record are:

      o     Value out of range

      o     Unknown value

      o     Field length invalid

      o     Value not included in a predefined set

The user can carry out further handling on the error records that BMP has saved
in a user-defined directory.

BMP allows for the same CDR information to be 'burst' to multiple locations.
This can be useful when more than one downstream PPS is interested in the same
information or a subset of it.

3.3.6 CDR Sequence Order Validation

The CDR sequence order validation feature ensures the sequential processing of
CDRs and that no CDRs in the CDR stream are missing or duplicated. The user can
specify the number

of error records ("out of sequence" records) which are accepted before
processing is aborted. BMP removes the error records from the stream and saves
them in a user-configurable directory.

CDR sequence order validation can be applied to CDRs containing a sequence
number field.\

3.3.7 Unique ID Generation

The unique ID generation feature inserts a unique ID in the CDRs for all switch
and service types collected by BMP. A data warehouse, for instance, could
require a unique ID.

3.3.8 Duplicate CDR Detection

The duplicate CDR detection feature ensures that no CDRs are duplicated in the
CDR stream. Duplicate checking can be done both within the same file and between
multiple files. The criteria for considering a CDR to be a duplicate are defined
by the user in the BMP GUI. Duplicate CDRs are stored in an error directory.

3.3.9 Time Gap Detection

The time gap detection feature ensures that there is an acceptable time gap
between two CDRs by comparing the time stamps in the CDRs. The function checks
the minimum and maximum acceptable time gaps between consequential CDRs. The
checking is also done between CDR files, i.e. between the last CDR of one file
and the first CDR of the next. Time Gap Detection can be used to validate that
CDRs are not missing.

3.3.10 CDR File Header/Trailer Generation & Validation

The header/trailer validation feature checks if particular fields of a CDR file
header/trailer are within a defined logic or range of values. Header/trailer
generation makes it possible to generate a new CDR file header and trailer or
modify the contents of an existing one. This is done by assigning values to new
fields in the header/trailer, modifying existing fields or concatenating
existing fields. The enhanced processing node can be used to extract information
from every CDR in a file, which can be used later on in header/trailer
generation.

3.3.11 Merge

Merge is a processing function in BMP that combines several input usage files
into a single, larger output file.

3.3.12 Enhanced Processing - Enhanced Processing Node

Enhanced processing is an extremely flexible building block, which makes it
possible to implement virtually any processing needed.

Enhanced processing in BMP consists of two different nodes, one based on the
JAVA programming language and one on the industry standard TCL script language.
It is possible to

                                                                      Appendix I

apply the same functionality (logic) in both kinds of node.

The Java node has been extended with a number of pre-defined classes and the TCL
node with a number of pre-defined primitives that give BMP the capability for
example to modify field values, access databases (for instance a subscriber
database) or do more complex format conversions. Enhanced processing also
provides capabilities for doing consolidation of partial CDRs and creating
consolidated usage reports by extracting relevant information from the CDRs.

Enhanced processing could be offered as a runtime license, i.e. EHPT or an EHPT
channel partner will do the set-up, or as a development license allowing the
service provider to define their own processing criteria.

3.3.13 Assignment

Assignment makes it possible to modify the contents of a CDR by adding fields,
assigning values to new fields, modifying already existing fields or
concatenating existing fields.

BMP supplies standard library functions (classes in Java and primitives in TCL)
for the most common and straightforward assignment of new values. Arithmetic
operations are also supported.

3.3.14 Database Look-up

The database look-up feature makes it possible to search internal or external
databases. The information gathered could be used for validation purposes or to
assign new information to existing fields in a CDR. TCL script primitives or
JAVA classes are available for the more common types of database searches.

BMP can retrieve values from the database and use return values to assign these
to new fields in the CDR.

                                                                      Appendix I

The consolidation function consolidates partial CDRs. It merges the CDRs that
belong to the same chargeable call into one CDR, typically long duration calls
or calls that go on during the "midnight shift", and sends it to the downstream
system. Consolidation is also a key functionality for handling both IP IPDRs and
GPRS CDRs in a GSM network, since information from many sources needs to be
consolidated into one chargeable record.

A selection node identifies the partial CDRs and sends them to the consolidation
node. The consolidation node keeps them waiting until it finds the matching
CDRs, and merges them into one.

The user can define criteria to identify the CDRs that belong to the same
chargeable call. The user can also define the criteria for how the different
fields should be merged before dispatching the consolidated CDR from the
consolidation function, for example to a billing system. It is also possible to
consolidate CDRs from different network elements.

3.3.16 Consolidated Usage Reports

By extracting information from CDRs passing a report (enhanced processing) node,
data can be extracted and stored in pre-defined tables in the BMP database. The
stored data can then be extracted and presented in customer-unique reports by
using for instance Oracle reports or an ODBC connection to Microsoft Excel or
Microsoft Access.

Examples of reports that could be created using the data in the pre-defined
table structure are:

      o     Total number of call minutes (or calls) per day per switch

      o     Total number of call minutes (or calls) per day per incoming and/or
            outgoing trunk/route

      o     Total number of call-minutes (or calls) per hour per switch etc

      o     Data volumes per hour per router (when receiving IPDRs from BMP IP)

3.3.17 Error handling in the processing nodes

Behavior when decoding or processing errors occurs is configurable. The
error-handling feature provides three options:

      o     -Abort on Max Fail. The processing node will abort when a user
            defined maximum number of erroneous CDRs has been reached. BMP
            writes all erroneous CDRs to an error directory until the maximum
            number is reached.

      o     Abort on First File. BMP writes the incorrect file to an error
            directory and the processing is stopped.

      o     Continue with next file. BMP writes the file with the erroneous CDRs
            to an error directory and automatically continues with the next
            file.

The decoding node can be set up to decode as much as possible of any faulty CDR
file,

hence all CDRs in a file that can be decoded will be decoded and passed to the
next processing node. The remaining CDRs will be stored in a file in an error
directory.

3.3.18 Distribution

The distribution function provides a flexible transfer of usage data files or
individual records to downstream applications, such as fraud and call behavior
analysis systems, billing and rating systems, other BMP systems, or to disks.
BMP supports:

      o     File transfer over FTP

      o     File transfer over FTAM

      o     Transfer of files or individual records over TCP/IP

      o     File transfer to disk, (local or NFS mounted)

      o     Transfer of files to another BMP system, using an InterBMP file and
            message transfer function

                                [GRAPHIC OMITTED]

                             Figure 12. Distribution

3.3.19 Distribution File Name Templates

The distribution file name templates feature allows the user to set the names of
the files to be distributed. The feature provides many name components to choose
from, such as qualifier, source, source file, job, separator between the name
parts, and type of data.

3.3.20 Post Processing Notification

When BMP has processed the CDRs and they have been distributed, it is sometimes
necessary to alert a post-processing system, such as a billing system.

BMP offers the possibility to start a script when a file has been closed and
distributed. The user defines the script and can for example choose to send a
mail to inform the post-processing system that the file is ready.

3.3.21 Base System

BMP base system includes the basic capabilities of BMP. These are described
below under the following headings:

      o     Scheduling

      o     Business Rules Builder

      o     Management

      o     On-line documentation

      o     User access and security

      o     Scalability

      o     Additional management application & Remote management

3.3.22 Scheduling

BMP provides an extensive scheduler, which allows the user to configure and
specify when BMP will perform collection, processing and distribution. The
scheduler, which is an internal subsystem of BMP, serves as a central control
point that is responsible for starting and maintaining jobs, handling requests
from the GUI and so on.

There are three types of scheduling that can be applied to the groups within a
BMP job: periodic, file close and external request. Periodic scheduling and
external request can be used for all collection, processing and distribution
groups, while file close scheduling can be used for processing and distribution
groups only.

3.3.23 Periodic Scheduling

There are three different types of periodic scheduling trigger: weekly, daily or
at an absolute time. BMP can combine multiple schedule configurations to define
a running schedule that specifies when a group within a job will be triggered.
When the time configured for the group is reached, the BMP system will start the
group.

Weekly and daily scheduling can have periodic repeat schedules according to the
setting of a repeat interval parameter. Both schedules can have two parameters,
an activation time and a repeat interval. The activation time specifies when the
schedule will become active. For a weekly schedule, this is a day of the week
plus a time of the day. For a daily schedule, it is simply a time during the
day. The repeat interval specifies the interval between each schedule trigger.

Absolute schedules have an absolute activation time, but no repeat interval
associated with them.

3.3.24 File Close Scheduling

There are two types of file close scheduling; one is based on the number of
files queued up

--------------------------------------------------------------------------------

                                                                      Appendix I

from the previous group in the job chain, the other on the number of bytes
queued up from the previous group in the job chain.

Processing and distribution groups that are configured for file close scheduling
will be triggered immediately when the specified number of files or bytes is
available.

3.3.25 External Request

Scheduling using an external request can be applied to all groups in a job, but
the procedure for using this type of scheduling is dependent on the operation of
an operator-created application.

3.3.26 Business Rules Builder

With BMP's integrated Business Rules Builder, the processing flows are created
according to the customer's specific business rules. The business rules are
created or changed easily through BMP's comprehensive GUI, by combining icons
representing the different processing, collection and distributing nodes.

3.3.27 Management

BMP provides extensive functions for operating, administrating and maintaining
the BMP system, including:

      o     Monitoring

      o     Logging

      o     Data management

      o     Exception handling, recovery and back-up

3.3.28 Monitoring

The user can access a BMP monitoring window that displays information about
active jobs. The user can specify the type of data to be displayed for the jobs.
Information can be shown about the following:

      o     Job name

      o     Group type

      o     Job and group identifiers

      o     The data file currently being processed by the group

      o     The source name for the collection group

      o     The destination name for the distribution group

      o     The date and time of the monitored activity

The monitor data is continuously updated while a job is running, and shows the
transient information as the jobs are being executed.

3.3.29 Report Mechanism, Logging

The BMP system provides four logs, which hold data about jobs, user actions,
events and errors. These are:

      o     Audit log

      o     Event log

      o     User log

      o     Error log

A BMP cleanup function periodically clears data from the user and event logs.
The data in the audit and error logs are not affected by the cleanup. Only the
BMP system administrator can remove the data.

                                [GRAPHIC OMITTED]

                               Figure 13. Logging

3.3.30 Audit Log

The audit log window displays audit information about jobs. The information
displayed is dependent on the log level set for the job, which is
user-configurable.

For a specific job, the audit log can provide information about:

      o     The job name

      o     The file name

      o     The number of CDRs processed by the processing nodes

      o     The size of a file in bytes

      o     The source of the collected file(s)

      o     The name of the collection group

      o     The icon number of the processing feature

      o     The date and time of the audited activity

The number of CDRs processed by the processing node are displayed as:

      o     Incoming number of CDRs

      o     Outgoing number of CDRs

      o     Merged number of CDRs

      o     Saved number of CDRs

      o     Deleted number of CDRs

      o     Modified CDRs

BMP uses the audit log to maintain historical information about the processing
of received CDR files.

3.3.31 Event Log

The event log displays information about events and for jobs. The event log
displays:

      o     The type of event that BMP logged, for example job started, job
            stopped

      o     The job status, for example success or fail

      o     The name of the job as defined in a job definition window

      o     The BMP user associated with the event

      o     The date and time of the logged event

      o     Additional information concerning the event

BMP periodically clears the event log data after a configurable interval to
prevent the database from becoming full.

3.3.32 User Log

The user log displays information about actions and the user entities related to
these actions for a selected BMP user. The user log displays:

      o     The BMP user associated with the entry

      o     The selected maintenance area function manipulated

      o     Selected actions, for example delete, insert, log in, and logout

      o     The date and time for the log entry

      o     Information from the system about the logged entries

The user log shows the results of a user's interaction with the system. The type
and amount of information that BMP display is configurable. BMP periodically
clears the event log data after a configurable interval to prevent the database
from becoming full.

3.3.33 Error Log

The error log displays information about warning situations, error situations
and critical situations that have occurred in the system.

3.3.34 Data Management

The user can configure how often BMP should automatically remove files that have
been processed and distributed. BMP also surveys the database and alerts the
user when it is running out of disk space.

3.3.35 Exception Handling, Recovery and Back up

BMP stores all information about a job in its database. At a restart, BMP starts
from the last unprocessed file. For example, if a job consists of ten files and
an error occurs at file three, BMP starts with file four at start-up. BMP also
features on-line back up using internal BMP features.

3.3.36 On-line Documentation

User documentation is provided on-line in HTML format. The BMP User Guide,
Procedure manual and System Administrators guide can be viewed on-line, with
hyperlinks to all chapters and sub-chapters, in a Netscape or Microsoft Explorer
browser.

                                [GRAPHIC OMITTED]

                        Figure 14. On-line documentation

3.3.37 User Access and Security

There are two levels of user connection and authentication on BMP systems:

      o     The end user has to log in to the Unix system and provide a
            password. The work environment can be loaded without any possibility
            of running direct command lines

      o     The end user has to provide a second password when connecting to
            BMP\

BMP verifies the functions that are available to the user in the log on
procedure. After log-on, BMP connects with the system, and performs an authority
check. Each user has a profile (called user) which the BMP database
administrator sets up in the BMP system. This profile defines the user's
privileges for each BMP function.

BMP allows for two classes of users - the system administrator and the user.

3.3.38 System Administrator

The system administrator manages the overall BMP network, systems and
applications. The system administrator grants user privileges according to user
level activity.

The system administrator is the only one with authority to maintain BMP user
accounts and privileges and maintain BMP licenses.

The system administrator only allows the following actions:

      o     Maintain users, and their access rights

      o     Maintain the BMP authorization key. With this key, the user unlocks
            the different features in BMP

3.3.39 User

The user performs BMP node-specific operations. BMP traces user actions into a
user log. From this log, the user can at any time identify the user responsible
for each action. The user can change his or her password, if the old password
can be given.

Multiple levels of clearances provide high security. For example, it is possible
to enable/disable the following actions for each user:

      o     View

      o     Update/insert

      o     Delete

3.3.40 Scalability

BMP is scalable both in capacity and functionality.

Additional functionality can easily be introduced with no, or only minor,
changes to an existing BMP solution.

A single server BMP system is capable of handling a substantial volume of CDR
data and if this should not be enough, BMP can be installed in a distributed
solution containing two or more BMP systems. The system is still, however,
manageable from a central location using industry standard management tools and
specific BMP applications (see Remote Management/Additional Management
Applications).

EHPT recommends separate dimensioning for each implementation case. Factors to
consider when dimensioning a solution include: peak throughput, number of days
of on-line data storage needed, locations of servers at IT center or network
elements building, and the possible need for a high level of availability.

3.4 BMP, Additional Functionality

3.4.1 Web Manager

The Web Manager allows the user to monitor and supervise several EHPT BMP,
Initiator and BMP/Initiator IP Systems at a time from a Web browser (Netscape
Navigator or Communicator).

From each managed system the user can view:

      o     the status of the system

      o     system statistics

      o     data throughput

      o     the status of individual jobs

      o     the error log.

The Web Manager presents information on two different levels: 1) a systems
overview, with information for all supervised systems and 2) a system view, with
information for one selected supervised system.

In the system overview (1) the following information is displayed:

      o     A table with the system state, number of jobs, number of running
            jobs, and data throughput.

      o     A common alarm list for all systems, showing the most recent alarms.
            The alarm list can be filtered by severity.

From the system view as 2) the following information is displayed:

      o     All jobs on this system with current state and descriptions. The
            jobs can be started and stopped.

      o     The alarm list for this specific system. The alarm list can be
            filtered by severity.

The Web Manager consists of three parts: proxy, server and client. The proxy
runs on the same server as the supervised system and handles all connections
with the supervised system. The Server handles the connections between proxy and
client. The user interface runs on the client.

3.4.2 BNSI Agent

Remote alarm surveillance from EHPT SYNERGIZER can be done using the BNSI
functionality within BMP. Alarms received from an external NE will normally be
followed by an alarm clear message. The alarm can therefore be activated or
cleared in the NE. Alarms that have no clear messages are classified as
"events". If an alarm is classified as an event no message will automatically be
sent to notify that the fault has been corrected. The BNSI Agent has the
following functionality:

--------------------------------------------------------------------------------
                                                                      Appendix I

      o     Alarm Message Forwarding
            (BNSI Agent reads the BMP log file and translates errors into the
            BMSI alarm structure).

      o     Alarm Filtering
            (based on severity and whether the alarm should be sent or not).

      o     Heartbeat transmission
            (The BNSI Agent can send a heartbeat if no alarms have been
            forwarded within a set time limit).

3.4.3 SNMP Agent

An SNMP Agent forwards BMP errors as traps to a SNMP Manager enabling BMP to be
supervised centrally. The operator will be alerted when an abnormal event occurs
and can access information in order to take a decision on what action to take.
The functionality included in the SNMP agent is:

      o     Alarm Message Forwarding
            (The SNMP Agent reads the BMP log file and translates alarms into
            the SNMP alarm structure)

      o     Alarm Filtering
            (At three levels: Error, Disaster, Warning)

      o     Configurable Polling Time
            (The frequency (in seconds) at which the Agent polls the BMP log
            file)

      o     Configurable Destination IP Address
            (The destination IP of the Receiving SNMP Manager can be configured
            and is read by the agent at start up)

      o     Configurable SNMP Trap Type
            (i.e. SNMPV1 or SNMPV2 which is read at start up)

      o     'The SNMP Agent does not include a MIB.

3.4.4 Job Distribution

With the script-based job distribution functionality, BMP jobs can be extracted
from one BMP system, including all set-up information for that particular job,
and transferred to another BMP system, for instance BMP jobs from a test
environment into a production environment.

3.4.5 CDR Repair System

The BMP CDR Repair System (CDR RS) is a tool for examining, editing and
correcting erroneous CDR files to be able to reprocess them. It has an easy to
use GUI, which gives access to the following functionality:

o     Encode and decode CDR files

The CDR RS encodes and decodes all ASN.1 formats that BMP supports. When opening
a file the user chooses the file format and the external format. The CDR RS then
displays the internal formats that can be mapped to the selected external
format. All formats are fetched from the BMP dB and new formats must therefore
be added with BMP Format Builder before the CDR RS can use them.

When encoding a file from the internal ASN.1 format the previous external file
format will be utilised. However, the file can also be given a new name and/or
format, leaving the original file untouched.

o     Editing Data

Decoded data is displayed in a spreadsheet. Each column represents a CDR field
and each row a CDR number. New data can be typed directly into a CDR field or a
find/replace function can be utilised to enter correct data into the field. If
incorrect data has been entered or a field or a field is missing data, the field
will be marked and the user must re-enter correct data.

o     Filtering data

The CDRs displayed in the spreadsheet can be filtered. A filer only applies to a
single column. Multiple filters can be added to each column.

The system can be used as a tool for basic creation of CDR data for test
purposes.

3.4.6 High Availability

To attain a high level of availability, the BMP system can provide duplicated
data links toward the network elements. To prevent any loss of data, BMP uses
mirrored disks for secure storage of all data.

To further increase availability, BMP can be configured as a high availability
system where dual computer systems back each other up. During normal run-time,
the two BMP systems work completely independently of each other and run separate
jobs, but if a single hardware failure occurs the BMP package on that particular
hardware will migrate over to the other machine. The high availability function
therefore ensures the flow of BMP operations. The hardware investment is also
fully utilized, since both servers are running during normal operation. The
configuration shown below is not the complete hardware specification, but merely
an outline of the main parts.

3.5 Tools - Implementation and Adaptation

BMP provides very competitive tools for implementation and adaptation. These
tools, and a broad range of services ensure you can quickly deploy (and change)
a system adapted to your specific needs. The following tools and features exist:
Business Rules Builder, Format Builder, Enhanced Processing Node, Script
Invocations and a complete BMP Development Environment (BMP DevKit).

3.5.1 Business Rules Builder

With Business Rules Builder, processing flows can be created according to your
specific business rules. The business rules are created and changed easily
through BMP's comprehensive GUI - by combining icons representing the different
processing, collection and distributing nodes.

3.5.2 Script Invocations

There are a number of possibilities for adapting collection and distribution to
the environment that BMP is working in by invoking customer-unique scripts:

      o     Post Collection Notification, which offers the possibility to run a
            script after a file has been collected

      o     PPS Notification script, which offers the possibility to run a
            script when a file has been distributed

      o     Selection and Validation expressions can be built using the BMP GUI,
            but can also be built as separate scripts.

3.5.3 Enhanced Processing Node, Development License

Enhanced processing is an extremely useful tool, which enables you to virtually
implement any processing needed. Enhanced processing in BMP consists of two
different nodes; one based on the JAVA programming language and the other on the
industry standard TCL script language. It is possible to apply the same
functionality (logic) in both nodes.

The enhanced processing development license gives service providers the right to
develop their own processing schemes using the enhanced processing node.

The node can also be used as a runtime node when EHPT or EHPT channel partners
are implementing the processing to be applied.

3.5.4 Enhanced Format Builder

The Enhanced Format Builder (EFB) is a graphical tool designed to facilitate the
production of ASN.1 format definition files. EFB is used to build, edit and
verify the format definition files that define the structure of incoming,
internal and outgoing data in BMP.

3.5.5 BMP Development Environment (EHPT BMP DevKit)

With the proven BMP development environment, introducing completely new
collectors is easy. It is also possible to introduce completely new processing
or distribution features and to customise BMP to customer-specific needs.

     in Exhibit 5 hereto. The Operating Rules may be amended based on a written
     proposal of the Lessor subject to a written approval of the Lessee acting
     in a good faith, provided however, that if the Lessee does not respond to
     such Lessor's proposal within five (5) business days from its delivery to
     the Lessee, such proposal will be deemed to be automatically approved by
     the Lessee without any further formalities.

                                      III.
                                  TERM OF LEASE

                                       IV.
                             RENT AND MARKETING FEE

1.   The rent for the Premises was set on the basis of a mutual consent of the
     contracting parties in accordance with applicable laws and regulations, and
     amounts to 14.57 EUR (in words: Fourteen point Five Seven Euro) per one
     square meter of the actually leased Premises per month, excluding VAT (the
     "Rent"). The applicable value added tax shall be calculated in accordance
     with applicable laws. The obligation of the Lessee to pay the Rent will
     begin on the Commencement Date. The first payment of the Rent shall be made
     not later than on the fifth (5th) day prior to the Commencement Date as per
     the invoice due for the period between the Commencement Date and the last
     day of the first complete calendar quarter issued by the Lessor and
     delivered to the Lessee not later that on the twentieth (20th) day prior to
     the Commencement Date. Thereafter, the Rent shall be payable quarterly in
     advance, against an invoice issued by the Lessor and delivered to the
     Lessee not later that on the fifth (5th) day prior to the first (1st) day
     of the first month of the relevant quarter, not later than on the tenth
     (10th) day of the first month of the relevant quarter; the date of payment
     shall be the date of receipt of payment on the Lessor's account.

                                      -5-

2.   Lessee shall reimburse the Lessor for its "proportionate share" of all
     expenses that shall be effected by the Lessor in accordance with an annual
     marketing plan and an annual budget for marketing expenses of the POLUS
     City Center Bratislava which documents will be delivered by the Lessor to
     the Lessee without undue delay after their completion (the "Marketing
     Fee"). As of the Commencement Date, the Marketing Fee will amount to two
     (2) EURO per square meter per calendar month excluding VAT and shall be
     payable together with the Rent. The Marketing Fee is not included in the
     Services and Utilities

     For the purposes hereof the expression "proportionate share" shall mean the
     fraction the numerator of which shall be the amount of sq. meters of the
     actually leased Premises and the denominator of which shall be the sum in
     sq. meters of all then rented retail premises in the Building; provided
     however, that the denominator shall in no event be lower that 26,135 sq.
     meters which represents 80% of the total rentable area in the Building.

3.   The Rent and the Marketing Fee shall be adjusted by a written notice from
     the Lessor to the Lessee, on an annual basis as of January 1 by a
     percentage corresponding to the percentage growth value of the German
     consumer price index (German Consumer Price Index - 4 person household
     published by the German Statistical Agency with its seat in Wiesbaden)
     (hereafter the "German Consumer Price Index") for the previous calendar
     year. Any such increase of the rent due to inflation, however, shall not
     exceed the maximum limit of 3% (three per cent) in any calendar year. The
     rent shall not be adjusted due to inflation if the change in the German
     Consumer Price Index does not exceed 1% (one per cent) in the relevant
     calendar year. However changes of less than or equal to 1 % (one per cent)
     in the German Consumer Price Index in one calendar year shall be added to
     the percentage growth value of the German Consumer Price Index in the
     immediately following year until such changes exceed 1 % (one per cent).
     The first adjustment of the Rent shall not be made earlier than as of
     January 1, 2002.

4.   The Rent and the Marketing Fee shall be payable in Slovak crowns, converted
     from Euro at the exchange rate of the National Bank of Slovakia as in
     effect on the 2nd Wednesday preceding the invoiced quarter, and shall be
     paid to the Lessor's account No. 2008005497/1100 at Tatra banka, a.s., with
     its seat at Vajanskeho nabrezie 5, 810 00 Bratislava, or such other
     account as may be notified by the Lessor to the Lessee in writing from time
     to time but not later than thirty (30) days prior to the respective
     payment. The Lessor shall charge the Lessee with VAT on the Rent at the
     rate specified by then applicable laws of the Slovak Republic and such
     amount shall be paid by the Lessee to the Lessor's account No.
     2625007738/1100 at Tatra banka a.s., with its seat at Vajanskeho
     nabrezie 5, 810 00 Bratislava, or such other account as may be notified
     by the Lessor to the Lessee in writing from time to time but not later than
     thirty (30) days prior to the respective payment.

                                      -6-

5.   The interest rate upon defaults in payment of the Rent and the Marketing
     Fee shall be 9% (nine per cent) per year if not stipulated otherwise by
     mandatory Slovak laws, calculated per diem.

6.   In the event that the Premises cannot be used for reasons which were not,
     in whole or in part, caused by any fault on the part of the Lessee,
     including but not limited to the situations where (i) the Lessor,
     notwithstanding the Lessee's written notice, fails to remove a defect in
     the Premises which affects the use of the Premises for the contemplated
     purpose, (ii) the services which the Lessor is obligated to provide and
     which lie within the control of the Lessor were not properly provided and,
     as a result, the use of the Premises has become aggravated, or (iii) any
     structural modifications in the Building undertaken or ordered to be
     undertaken by the Lessor resulted in an aggravation of the conditions of
     use of the Premises; the Lessee shall be entitled to a respective pro-rata
     discount from the rent. Similarly, the Lessee shall also be entitled to an
     adequate reduction of the rent if, as a result of the Lessor's activities,
     the conditions of the use of the Premises become restricted. The Lessee
     shall only be entitled to such discount from or reduction of the rent for
     the period of the time for which the Premises could not be used or their
     use was restricted.

                                       V.
                  SERVICES AND UTILITIES AND ADMINISTRATION FEE

1.   The parties hereto have agreed that the Lessee shall reimburse the Lessor
     for its "proportionate share" of any and all costs (i) of all services
     related to the operation of the Building and of the Premises as categorized
     in Exhibit 6 (hereafter the "Services and Utilities") hereto which forms an
     integral part hereof, and (ii) of heating, ventilation and air-conditioning
     of the Building. The Lessee shall pay to the Lessor an administrative fee
     of fifteen (15) % of the Lessee's proportionate share of the cost of those
     services and utilities in Exhibit 6 which are subject to the administrative
     fee (the "Administrative Fee"). The Administrative Fee shall be payable at
     same time and on the same terms and conditions as the Lessee's
     "proportionate share" of such services and utilities, provided, however,
     that the Lessee shall start to reimburse the Lessor for the Lessee's
     "proportionate share" of the costs of the Services and Utilities together
     with the Administration Fee as of January 1, 2001. Whenever practicable and
     permitted by law, the Lessee shall enter into direct contractual
     relationships with providers of services and utilities and pay directly to
     them the respective costs and expenses for such services and utilities.

2.   The initial readings of the electrometer and water meter shall be recorded
     in the protocol of conveyance and take-over of the Premises.
<PAGE>

                                      -7-

3.   At the commencement of the lease, the Lessor shall disclose to the Lessee
     the estimated annual costs payable under all maintenance and service
     agreements. The Lessor hereby agrees that the actual costs pursuant to such
     aforementioned service agreements shall in no event be higher than usual
     costs of services of comparable quality in comparable real estate
     developments in Bratislava if any. As of the Commencement Date, the
     Lessee's "proportionate share" of any and all costs of the Services and
     Utilities will amount to approximately 4 EUR per square meter per calendar
     month excluding VAT.

     For the purposes hereof the expression "proportionate share" shall mean the
     fraction the numerator of which shall be the amount of sq. meters of the
     actually leased Premises and the denominator of which shall be the sum in
     sq. meters of all then rented retail premises in the Building; provided
     however, that the denominator shall in no event be lower that 26,135 sq.
     meters which represent 80% of the total rentable are in the Building.

4.   The Lessor shall submit to the Lessee separate invoices for the Services
     and Utilities provided by the Lessor. The issuance, delivery and payment
     terms of such invoices shall be the same as with respect to invoices
     relating to the Rent pursuant to Article IV above; provided that the
     amounts due thereunder shall be payable by the Lessee in Slovak crowns to
     the Lessor's account specified in Article IV(4) above.

5.   The Lessee shall pay VAT on the Services and Utilities.

                                       VI.
                          TERMS AND CONDITIONS OF LEASE

1.   The Lessor shall be obligated to deliver the Premises on the Commencement
     Date in the condition suitable for the agreed purpose of the lease as set
     forth in Article II hereof, to maintain the Premises in the condition fit
     for the agreed use hereunder, and to secure the proper performance of the
     services the provision of which is connected to the use of the Premises.

2.   The Lessor shall be obligated to ensure to the Lessee the right to an
     undisturbed use of the Premises, use of the common spaces in the Building,
     the access necessary for the use of the Premises, and also the right to a
     use of elevators in the Building.

     increase in insurance premium payable by the Lessor, provided however, that
     the Lessor (i) notifies the Lessee in writing, and (ii) proves to the
     Lessee, that such action taken by the Lessee would cause such increase.

4.   The Lessee agrees to maintain such insurance policy as would be reasonably
     expected from a prudent businessman to maintain for the type of business
     activities to be conducted by the Lessee in the Premises, including without

Failure on the part of any party to perform any of its obligations set forth in
this Agreement because of a force majeure will not give the other party to this
Agreement any claim against the other party or be deemed to be a breach of this

event of such force majeure shall give notice in writing of such force majeure
as soon as possible after occurrence to the other party. For the purpose of this
Agreement, force majeure shall mean any war, revolution, civil disorder,
sabotage, strike or lock out involving third parties, accident, act of God,
laws, regulations and acts of any governmental agency of the Slovak Republic or

an event of force majeure occurs and such event materially interferes with any
party's ability to perform its obligations hereunder for a continuous period of
six months (or it becomes evident that such event will continue for a continuous
period of six months), the obligations of such party shall terminate and the
other party shall be entitled to damages suffered as a result of such
termination payable by the party whose obligations were terminated under this
Article XIV.

     Agreement. However, if they are unable to resolve any dispute by amicable
     settlement, such dispute shall be finally settled by the Slovak court
     having jurisdiction.

     holders of any such mortgages or liens or their agents with a right of
     entry to the Premises to inspect the Premises during normal working hours
