<PAGE>

                    shall immediately correct any defect for which it may be
                    responsible. Upon successful Site Acceptance Test, an Site
                    Acceptance Certificate shall be issued by AZCOM within five
                    (5) working days. In case the Network is put into commercial
                    operation by AZCOM before the Initial Acceptance without
                    ACL's written approval, the Site acceptance certificate
                    shall be deemed to have been issued by AZCOM at the time of
                    commencement of commercial operation.

        9.1.3  Performance Monitoring

               During the Warranty Period the Network shall, at AZCOM
               discretion, be tested to ensure that the System Performance is in
               line with the System Specifications.

               These tests shall be as follows

               .  System Functionality Test
               .  Long Term BER Tests

               If the test fails again ACL shall be given 30 days to apply
               corrective action. If after 30 days no corrective action has been
               taken or a subsequent test again fails, the System under test
               shall be deemed to have failed Performance Monitoring and the
               Warranty Period shall be extended.

               Once a system has failed Performance Monitoring ACL shall be
               required to take corrective action, including the complete
               replacement of the system in question.

          9.1.5     In case the System fails to meet the acceptable performance
                    monitoring standards within two (2) years from the date of
                    Acceptance, the Parties shall confer within thirty (30) days
                    from the date such failure becomes apparent to discuss the
                    possible solutions to the problem which solutions shall
                    include, but not be limited to, the correction of any
                    defect, the repair or replacement of parts, the replacement
                    of the equipment with another which complies with the
                    required performance standards or the payment by ACL to
                    AZCOM of all costs necessary to enable the System to comply
                    with acceptable performance standards. Notwithstanding the
                    foregoing and in case the Parties reach no agreement within
                    sixty (60) days from their initial meeting, ACL shall
                    replace, at no cost to AZCOM, the equipment concerned with
                    another equipment which complies with the performance
                    standards. If at the end of the above-mentioned sixty (60)
                    days period no replacement equipment is available or the
                    replacement equipment is available or the replacement
                    equipment still does not comply with the performance
                    standards, then ACL shall pay AZCOM all the cost necessary
                    for AZCOM to undertake measures, on its own, to make the
                    System comply with acceptable performance standards.

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

     The Parties shall be liable only for damages directly caused through their
     own fault or negligence.

                                       15
<PAGE>

18   FORCE MAJEURE
     -------------

     18.1 The Parties shall not be liable for the non-performance of any of its
          obligations under this Contract when such inability is due solely to
          an event of force majeure  which (a) directly affects the performance
          of a Party's obligations under this Contract and (b) the occurrence of
          which event is not traceable to the fault or negligence of the said
          Party.

     18.2 The events of force majeure shall include, but not be limited to: (a)
          earthquakes, floods, typhoons, or epidemics; (b) war, rebellion,
          insurgency, riots, or invasion of the Philippines by another country;
          (c) strikes, lockouts, boycotts or other forms of work stoppage; and
          (d) government embargo, restriction, or commandeering of the vessel
          carrying the Equipment.

     18.3 In case an event of force majeure happens, the affected Party shall
          exert its best efforts to comply with its obligations under this
          Contract. If an event of force majeure prevents the carrying out of
          only a portion of the Project and that portion is not critical to the
          accomplishment of the Project as a whole, the affected Party shall
          continue to perform its obligations on the portion not affected by the
          event of force majeure.

     18.4 The Party invoking an event of force majeure must immediately notify
          in writing the other Party and specify which of its obligations it is
          prevented from complying with by the event of force majeure, and give
          an estimate of the period during which it is likely that it shall be
          prevented from complying with the said obligations. After the
          occurrence of the event of force majeure is proven, the Schedule and
          the performance bond may, after discussions in good faith, be amended
          by Contract of the Parties.

     18.5 The amendment of the Schedule pursuant to Section 18.4 shall not give
          ACL the right to seek or demand an adjustment or modification of the
          Price.

19   CHANGES
     -------

     ACL may, after prior approval of AZCOM, alter or modify the technology of
     the Equipment, provided that the alteration or modification is of an equal
     or greater functionality to the original. In case an increase or decrease
     in the Price results as a consequence of any alteration or modification of
     the Equipment, the appropriate adjustment of the Price, and where
     necessary, the Schedule, or both, shall be undertaken by the Parties.

     particular invalid or unenforceable part, term or provision.

23   SUCCESSION AND ASSIGNMENT
     -------------------------

     This Contract shall be binding upon the successors and assigns of the
     Parties and shall not be assigned in whole or in part by a Party without
     the prior written consent of the other party, and which consent shall not
     be unreasonably withheld.

24   TERMINATION
     -----------

     24.1 If either Party violates any provision of this Contract and if such
          default or violation continues for sixty (60) days after receipt of
          the Party in default of a written notice from the aggrieved Party, the
          aggrieved Party may terminate this Contract for any breach hereof by
          written notice to the other Party at least thirty (30) days prior to
          the intended date of termination.

     24.2 In the case of default on the part of ACL, AZCOM shall be entitled to
          retain and apply the balance, which may otherwise be due to ACL under
          this Contract to pay for the cost to complete the Project. If the said
          balance is not sufficient to cover the cost of the inoperative or non-
          functional Equipment or System, the additional cost needed to make the
          Equipment operative or functional shall be paid by ACL to AZCOM, upon
          termination of Contract.

     24.3 In the case of default on the part of AZCOM, AZCOM shall pay ACL the
          value of delivered Equipment.

25   ARBITRATION
     -----------

     25.1 In the event of any dispute or difference of opinion arising out of or
          relating to this Contract or breach thereof, the parties shall exert
          their best efforts to settle such dispute or difference amicably.

     25.2 If such dispute or difference is not amicably settled within sixty
          (60) calendar days from its occurrence, the matter shall be settled
          through arbitration by a panel of three (3) arbitrators, one to be
          named by each Party and the third arbitrator shall be chosen by the
          two earlier designated arbitrators. In case they fail to select a
          third arbitrator within fifteen (15)

                                       17
<PAGE>

          calendar days from the date they commenced the discussion of the said
          selection, the third arbitrator shall be appointed by the chairpersons
          of the National Bar Associations of the countries of the Parties. No
          one shall be nominated or act as an arbitrator who is in any way
          financially interested in this Contract or in the business affairs of
          any of the parties.

     25.3 If any Party is dissatisfied with the decision of the arbitrators, the
          Party concerned shall, within ten (10) calendar days from receipt of
          the decision, notify the arbitrators that it disputes the same and the
          matter shall thereupon be settled under the Rules of Conciliation and
          Arbitration of the International Chamber of Commerce. The arbitration
          proceedings shall be conducted in Geneva, Switzerland in the English
          Language. The resulting award shall be final and binding on the
          parties.

                performance thereof shall be dealt with in accordance with the
                following:

                9.1.6.1. In the event that the results of System Acceptance
                         Tests carried out are not in accordance with the
                         requirements of the Contract, action shall be taken by
                         ACL to locate and isolate the faults.

                9.1.6.2. Any faults located by ACL or notified to ACL by AZCOM
                         shall be rectified promptly by ACL.

                9.1.6.3. Each corrective action shall be performed by ACL and
                         witnessed by AZCOM. A detailed written report
                         containing particulars relating to the faults together
                         with the results of the re-testing shall be submitted
                         to AZCOM immediately after the corrective actions.

                9.1.6.4. ACL shall recommend the Equipment for re-testing only
                         when all faults have been corrected to meet the
                         requirement of the Contract. AZCOM may also perform
                         additional tests it deems necessary. Such additional
                         test procedures shall be agreed upon by both parties.

                9.1.6.5. The rectification of any particulars referred to in
                         this clause shall be carried out by ACL at its own
                         expense and effected promptly upon receipt of notice
                         thereof.

                9.1.6.6. If ACL fails to rectify any such particulars within a
                         reasonable time, AZCOM may elect to have any or all of
                         such particulars rectified through other means. In
                         which event ACL shall compensate AZCOM, within the
                         limits of ACL's liability under the Contract, for all
                         losses, damages, costs, charges, and expenses which
                         AZCOM may sustain by reason of ACL's failure to effect
                         the necessary corrective measures on the particulars
                         referred to.

        9.1.7.  Each System will be initially accepted after ACL has
                demonstrated to AZCOM that all the requirements of the
                Specifications have been complied with, and provided that the
                result shows that:

                a. the System is functioning properly according to the technical
                   specifications; and

                b. the requirements of the Contract have been met.

                In which event, ACL will be granted by AZCOM a certificate of
                System Acceptance five (5) days from the date of System
                Acceptance. The date of the certificate shall be the completion
                date of the stability test.

        9.1.8.  In the event that AZCOM does not grant a certificate of System
                Acceptance but nevertheless AZCOM and ACL mutually agree in
                writing that the System can be put in commercial service, ACL
                shall issue a waiver on their rights for the
<PAGE>

                issuance of System Acceptance certificate up to a certain period
                of time. Such shall not relieve ACL of his responsibility under
                this Contract and ACL shall continue to be responsible for any
                damage attributable to any part of the System which requires
                corrective action.

        9.1.9.  Items requiring corrective actions and items not provided shall
                be jointly identified by AZCOM and ACL. When the outstanding
                corrective action has been taken and the outstanding items
                delivered and approved by AZCOM in writing, a certificate of
                System Acceptance will be granted.

        9.1.10. After the execution of the System Acceptance Test protocol, the
                representative from AZCOM shall indicate the outcome of each
                test. Providing there are no major failures, the representative
                of AZCOM shall sign and date the test protocol, indicating that
                the System is acceptable.

9.2.    Performance Monitoring

        During the Warranty Period the Network shall be, at AZCOM's discretion,
        tested to ensure that the System performance is in line with the System
        specifications.

        These tests shall be as follows:

        - System Functionality Tests
        - Long Term BER Tests
        - Output Power Measurements on the Base Station

        Before any test is conducted, AZCOM shall notify ACL two weeks in
        advance that a test is to be conducted. ACL shall have the option of
        being present at any test. If a test is conducted whilst ACL is not
        present and the results are a failure, AZCOM shall notify ACL so that
        the test can be repeated after an investigation by ACL. If the test
        fails again ACL shall be given 30 days to apply corrective action. If
        after 30 days no corrective action has been taken or a subsequent test
        again fails, the System under test shall be deemed to have failed
        Performance Monitoring and the Warranty Period shall be extended.

        Once a system has failed Performance Monitoring ACL shall be required to
        take corrective action, including the complete replacement of the System
        in question.

        The System Functionality tests as defined by AZCOM may include, but are
        not limited to the following:

        - System Installation and Service Provisioning
        - System Connectivity: 64kbit/s and 128kbit/s Leased Line Data
          Services
        - Network Management System functionality test

        The Long Term BER Test shall be:
        - 168 hour BER. A Pass shall be when the average BER is better than
        10/-7/.

        The Output Power Test shall be:
        - CT Output Power is within 1.5dB of commissioned level.

                test.

        9.3.3.  This test shall be conducted once and shall be considered as
                final. After passing the acceptance test successfully,
                acceptance certificate for Spares and tools and test equipment
                shall be issued within two (2) weeks therefrom. If AZCOM does
                not issue the said certificate within two (2) weeks for reasons
                not attributable to the fault of ACL, the acceptance certificate
                shall be deemed to have been issued by AZCOM.

        9.3.4.  Warranty of Spares, tools and test equipment shall be for
                eighteen (18) months from the date of Acceptance.

9.4.    Subscriber Terminal Acceptance Test

        Upon the delivery of the Subscriber Terminals to ACL's warehouse in the
        Philippines, an acceptance test shall be performed. After a successful
        ST Acceptance Test and subsequent issuance of an Acceptance Test
        Certificate by AZCOM the Warranty Period on the subscriber terminals
        shall start.

        The Subscriber Terminal Acceptance Test shall be in two parts. The
        second test shall only be undertaken if the first test fails.

        The first test shall be a sample test. AZCOM shall randomly select 4% of
        subscriber terminals within a delivery batch. These terminals shall be
        tested for normal leased line data operation, and be given a 60-minute
        BER test conducted over the air. The BER results shall be better than
        10 /-7/.

        If during this first test more than 20% of the terminals fail, the
        second test shall be performed. If less than 20% of the terminals fail
        the whole batch of Subscriber Terminals shall be accepted and a
        successful acceptance test certificate issued.

        The second test shall be a complete test of all the subscriber
        terminals. This test shall be for normal leased line data operation, and
        include a 60-minute BER test conducted over the air. The BER results
        shall be better than 10 /-7/. Only Subscriber Terminals that pass
        this test shall be accepted by AZCOM.

service provider's local access network.                              .  Supports a full range of telecommunication services:
                                                                         telephony, fax, in-band data modems, leased line data
These systems enable 32kbit/s and 64 kbit/s telephony,                   and basic rate ISDN
56 kbit/s modem connectivity, 2B+D ISDN, 128 kbit/s leased
lines, and internet solutions for business and residential            .  Full public network compatibility, with low delay and
applications.                                                            full service transparency

Designed to provide near line-of-sight wide-area                      .  Highly efficient use of radio spectrum
coverage, the systems operate over distances up to 25km.
                                                                      .  Inherently secure radio interface
AS4000 systems connect to the telephony network via a
standard local exchange/central office switch interface,              .  Simple to install, operate and maintain
and to data and packet networks using standard 2Mbits
and 1.5Mbps interface technologies.                                   .  Meets ETSI TM4 P-MP DS-CDMA Specification (ETS 301 055)

A wide range of ST types are available. These include units for       .  Operates in numerous bands between 1.35 to 4.0 GHz
analogue telephony (single, dual, four and multi-line variants);
128kbit/s digital leased lines; Basic Rate ISDN; and packet           .  Supports up to 2000 64kbit/s telephony lines per cell
data terminals. The ST comprises a compact and unobtrusive radio
unit which is mounted externally at the end-user's premises, a
drop cable that connects the radio unit to an internal unit, and
regular network termination points. The radio unit includes an
integrated flat-plate antenna that can be installed and maintained
without any specialist radio knowledge.

Airspan's Radio Base Stations are named "Central Terminals" (CTs).
These provide the radio link to the Subscriber Terminals (ST) which
are deployed at the end-users' locations. In addition the CTs
provide connectivity to an operator's switch, to an Access
Concentrator (AC) for "Demand Assigned" operation, or to datacomms
equipment. Network interfaces supported include 2-Wire VF, 2Mbits
G.703 with CAS in TS16, DASS2, DSS1, V5.1 or V5.2 signalling schemes.
T1 (1.5Mbit/s) interfaces and signalling schemes are also supported.

System Management is provided through craft terminals, distributed
scaleable PC solutions and/or a TMN (M.3010) Element Manager (SMP),
which provides a full Q3 interface to higher network layers.

     .  Can be deployed as an overlay network providing premium
        services

     .  Provides 'better than copper' service quality

     .  Provides a cost efficient backhaul alternative for
        cellular / cordless networks, e.g. GSM/DECT/PHS

     .  Provides a cost-effective solution to relieve feeder
        congestion.

Deployment
Airspan AS4000 systems may be deployed either stand-alone or in conjunction with
other access technologies, and are currently operational in more than 30
operators' networks world-wide.

The CT equipment is modular in design, which allows a high degree of flexibility
for provision of multiple services, for cost effective initial provisioning, and
for easy system expansion. The modular nature of the equipment also enables fast
installation and maintenance, and minimises spares inventories.

The design of the subscriber units enables fast installation by a non-specialist
workforce.

The following pictures show examples of AS4000 equipment and deployments.

System Architecture
The following diagram shows the various elements in an Airspan AS4000
deployment.

Note that the CT sites are usually at remote locations (chosen for their radio
coverage) and the traffic is then backhauled to the switch using point-to-point
radio or fibre links.

In "Demand Assigned" (DA) operation the addition of an "Access Concentrator"
(AC) provides the traffic concentration functions and allows flexible
interfacing to the host switching network. This is normally located at the
switch site and allows the traffic from multiple CTs at a number of separate
sites to presented on unified interfaces to the switch.

The following diagram shows the DA architecture:

     10.4 In consideration of the aggressive schedule of the Project
          Implementation as shown in Annex B, ACL shall be allowed extra time to
          meet the schedule date of completion as follows:

          .  For the sites to be completed in November       : 60 days
          .  For the sites to be completed in December       : 60 days
          .  For the sites to be completed in January        : 30 days
          .  For the sites to be completed in February       : 15 days

          The above means that liquidated damages can only be claimed by AZCOM
          against ACL after the above extension time has likewise been exceeded.

     10.5 The claim of AZCOM for liquidated damages against ACL shall not
          prejudice the exercise of AZCOM of its other right and privileges
          under the contract.

     10.6 Any deferment on the part of AZCOM to remit the downpayment within ten
          (10) days of Contract signing shall allow ACL an extension equivalent
          to the number of days AZCOM has delayed in the remittance of the
          downpayment from the said ten (10) day period.

11   LIMITATION OF LIABILITY
     -----------------------

     The Parties shall be liable only for damages directly caused through their
     own fault or negligence.

12   FORCE MAJEURE
     -------------

     12.1 The Parties shall not be liable for the non-performance of any of its
          obligations under this Contract when such inability is due solely to
          an event of force majeure which (a) directly affects the performance
          of a Party's obligations under this Contract and (b) the occurrence of
          which event is not traceable to the fault or negligence of the said
          Party.

     12.2 The events of force majeure shall include, but not be limited to: (a)
          earthquakes, floods, typhoons, or epidemics; (b) war, rebellion,
          insurgency, riots, or invasion of the Philippines by another country;
          (c) strikes, lockouts, boycotts or other forms of work stoppage; and
          (d) government embargo, restriction, or commandeering of the vessel
          carrying the Equipment.

     12.3 In case an event of force majeure happens, the affected Party shall
          exert its best efforts to comply with its obligations under this
          Contract. If an event of force majeure prevents the carrying out of
          only a portion of the Project and that portion is not critical to the
          accomplishment of the Project as a whole, the affected Party shall
          continue to perform its obligations on the portion not affected by the
          event of force majeure.

     12.4 The Party invoking an event of force majeure must immediately notify
          in writing the other Party and specify which of its obligations it is
          prevented from complying with by the event of force majeure, and give
          an estimate of the period during which it is likely that it shall be
          prevented from complying with the said obligations. After the
          occurrence of the event of force majeure is proven, the Schedule and
          the performance bond may, after discussions in good faith, be amended
          by Contract of the Parties.

     12.5 The amendment of the Schedule pursuant to Section 12.4 shall not give
          ACL the right to seek or demand an adjustment or modification of the
          Price.

13   CHANGES
     -------

     13.1 Any request by AZCOM for a change in the Work or any part thereof
          shall be subject to the conformity of ACL.  Such request shall be
          subject to later written confirmation by AZCOM.  The additional cost
          and expenses which may arise on account of such changes, if any, shall
          be borne by AZCOM, and the date of completion of the Work may be
          extended by agreement of the parties.

     13.2 ACL may, with the consent of AZCOM, make minor adjustments in the Work
          as, in its sole discretion, may appear necessary for the proper
          accomplishment of its obligations under this Contract. The said
          adjustments shall be subject to the following conditions: (a) the
          general configuration, general characteristics and quality of the Work
          are maintained;

                                       17
<PAGE>

          (b) the Schedule is not changed or modified; (c) any additional costs
          or expenses which may arise as a consequence of such adjustments shall
          be for the account of ACL; and (d) such adjustments shall be reported
          in writing to AZCOM.

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

     If any part, term or provision of this Contract shall become invalid or
     unenforceable, the validity or enforceability of the remaining portions or
     provisions shall not be affected, and the rights and obligations of the
     parties shall be construed as if this Contract did not contain the
     particular invalid or unenforceable part, term or provision.

17   SUCCESSION AND ASSIGNMENT
     -------------------------

     17.1 This Contract shall be binding upon the successors and assigns of the
          Parties and shall not, except as otherwise provided in Section 18.2
          hereof, be assigned in whole or in part by a Party without the prior
          written consent of the other party, and which consent shall not be
          unreasonably withheld.

     17.2 ACL may assign or sub-contract to its subsidiary or associated company
          in the Philippines or any other local entity its rights and
          obligations which ACL decides may be more appropriately performed by
          its subsidiary or associated company in the Philippines or other local
          entity. Before any such assignment or sub-contracting is entered into
          by ACL, it shall seek the comments of AZCOM on such intended course of
          action. However, AZCOM's comments shall not relieve or diminish ACL's
          obligations and responsibilities under this Contract. ACL shall
          continue to be responsible for the workmanship and quality of the work
          of the assignee or sub-contractee, including all acts of default or
          negligence of such

                                       18
<PAGE>

          assignee or sub-contractee, its employees or personnel, as if they
          were the acts of default or negligence of ACL. There is no employer-
          employee relationship between the employees of ACL and AZCOM and vice-
          versa.

18   TERMINATION
     -----------

     18.1 In case of default on the part of ACL:

          18.1.1  If ACL fails to comply with any of the terms and conditions of
                  this Contract after proper written notice by AZCOM, AZCOM
                  shall have the right to terminate this Contract thirty (30)
                  days after a notice of termination has been served on ACL.

          18.1.2  In the event of such termination, AZCOM shall be entitled to
                  retain and apply the balance, which may otherwise be due to
                  ACL under this Contract to pay for the cost to complete the
                  Project. If the said balance is not sufficient to cover the
                  cost of the inoperative or non-functional Equipment or System,
                  the additional cost needed to make the Equipment operative or
                  functional shall be paid by ACL to AZCOM

     18.2 In case of default on the part of AZCOM:

          18.2.1  If AZCOM fails to comply with any of the terms and conditions
                  of this Contract after proper written notice by ACL, ACL shall
                  have the right to terminate this Contract thirty (30) days
                  after a notice of termination has been served on AZCOM.

          18.2.2  In case of such termination, AZCOM shall pay ACL the value of
                  the delivered Equipment and release the performance bond
                  submitted by ACL.

19   ARBITRATION
     -----------

     19.1 In the event of any dispute or difference of opinion arising out of or
          relating to this Contract or breach thereof, the parties shall exert
          their best efforts to settle such dispute or difference amicably.

     19.2 If such dispute or difference is not amicably settled within sixty
          (60) calendar days from its occurrence, the matter shall be settled
          through arbitration by a panel of three (3) arbitrators, one to be
          named by each Party and the third arbitrator shall be chosen by the
          two earlier designated arbitrators. In case they fail to select a
          third arbitrator within fifteen (15) calendar days from the date they
          commenced the discussion of the said selection, the third arbitrator
          shall be appointed by the chairpersons of the National Bar
          Associations of the countries of the Parties.  No one shall be
          nominated or act as an arbitrator who is in any way financially
          interested in this Contract or in the business affairs of any of the
          parties.

     19.3 If any Party is dissatisfied with the decision of the arbitrators, the
          Party concerned shall, within ten (10) calendar days from receipt of
          the decision, notify the arbitrators that it

                                       19
<PAGE>

          disputes the same and the matter shall thereupon be settled under the
          Rules of Conciliation and Arbitration of the International Chamber of
          Commerce. The arbitration proceedings shall be conducted in Geneva,
          Switzerland in the English Language. The resulting award shall be
          final and binding on the parties.

                         limits of ACL's liability under the Contract, for all
                         losses, damages, costs, charges, and expenses which
                         AZCOM may sustain by reason of ACL's failure to effect
                         the necessary corrective measures on the particulars
                         referred to.

        9.1.7.  Each System will be initially accepted after ACL has
                demonstrated to AZCOM that all the requirements of the
                Specifications have been complied with, and provided that the
                result shows that:

                a. the System is functioning properly according to the technical
                   specifications; and

                b. the requirements of the Contract have been met.

                In which event, ACL will be granted by AZCOM a certificate of
                System Acceptance five (5) days from the date of System
                Acceptance. The date of the certificate shall be the completion
                date of the stability test.

        9.1.8.  In the event that AZCOM does not grant a certificate of System
                Acceptance but nevertheless AZCOM and ACL mutually agree in
                writing that the System can be put in commercial service, ACL
                shall issue a waiver on their rights for the
<PAGE>

                issuance of System Acceptance certificate up to a certain period
                of time. Such shall not relieve ACL of his responsibility under
                this Contract and ACL shall continue to be responsible for any
                damage attributable to any part of the System which requires
                corrective action.

        9.1.9.  Items requiring corrective actions and items not provided shall
                be jointly identified by AZCOM and ACL. When the outstanding
                corrective action has been taken and the outstanding items
                delivered and approved by AZCOM in writing, a certificate of
                System Acceptance will be granted.

        9.1.10. After the execution of the System Acceptance Test protocol, the
                representative from AZCOM shall indicate the outcome of each
                test. Providing there are no major failures, the representative
                of AZCOM shall sign and date the test protocol, indicating that
                the System is acceptable.

9.2.    Performance Monitoring

        During the Warranty Period the Network shall be, at AZCOM's discretion,
        tested to ensure that the System performance is in line with the System
        specifications.

        These tests shall be as follows:

        - System Functionality Tests
        - Long Term BER Tests
        - Output Power Measurements on the Base Station

        Before any test is conducted, AZCOM shall notify ACL two weeks in
        advance that a test is to be conducted. ACL shall have the option of
        being present at any test. If a test is conducted whilst ACL is not
        present and the results are a failure, AZCOM shall notify ACL so that
        the test can be repeated after an investigation by ACL. If the test
        fails again ACL shall be given 30 days to apply corrective action. If
        after 30 days no corrective action has been taken or a subsequent test
        again fails, the System under test shall be deemed to have failed
        Performance Monitoring and the Warranty Period shall be extended.

        Once a system has failed Performance Monitoring ACL shall be required to
        take corrective action, including the complete replacement of the System
        in question.

        The System Functionality tests as defined by AZCOM may include, but are
        not limited to the following:

        - System Installation and Service Provisioning
        - System Connectivity: 64kbit/s and 128kbit/s Leased Line Data
          Services
        - Network Management System functionality test

        The Long Term BER Test shall be:
        - 168 hour BER. A Pass shall be when the average BER is better than
        10/-7/.

        The Output Power Test shall be:
        - CT Output Power is within 1.5dB of commissioned level.

These systems enable 32kbit/s and 64 kbit/s telephony,                   and basic rate ISDN
56 kbit/s modem connectivity, 2B+D ISDN, 128 kbit/s leased
lines, and internet solutions for business and residential            .  Full public network compatibility, with low delay and
applications.                                                            full service transparency

Designed to provide near line-of-sight wide-area                      .  Highly efficient use of radio spectrum
coverage, the systems operate over distances up to 25km.
                                                                      .  Inherently secure radio interface
AS4000 systems connect to the telephony network via a
standard local exchange/central office switch interface,              .  Simple to install, operate and maintain
and to data and packet networks using standard 2Mbits
and 1.5Mbps interface technologies.                                   .  Meets ETSI TM4 P-MP DS-CDMA Specification (ETS 301 055)

A wide range of ST types are available. These include units for       .  Operates in numerous bands between 1.35 to 4.0 GHz
analogue telephony (single, dual, four and multi-line variants);
128kbit/s digital leased lines; Basic Rate ISDN; and packet           .  Supports up to 2000 64kbit/s telephony lines per cell
data terminals. The ST comprises a compact and unobtrusive radio
unit which is mounted externally at the end-user's premises, a
drop cable that connects the radio unit to an internal unit, and
regular network termination points. The radio unit includes an
integrated flat-plate antenna that can be installed and maintained
without any specialist radio knowledge.

Airspan's Radio Base Stations are named "Central Terminals" (CTs).
These provide the radio link to the Subscriber Terminals (ST) which
are deployed at the end-users' locations. In addition the CTs
provide connectivity to an operator's switch, to an Access
Concentrator (AC) for "Demand Assigned" operation, or to datacomms
equipment. Network interfaces supported include 2-Wire VF, 2Mbits
G.703 with CAS in TS16, DASS2, DSS1, V5.1 or V5.2 signalling schemes.
T1 (1.5Mbit/s) interfaces and signalling schemes are also supported.

System Management is provided through craft terminals, distributed
scaleable PC solutions and/or a TMN (M.3010) Element Manager (SMP),
which provides a full Q3 interface to higher network layers.

     .  Can be deployed as an overlay network providing premium
        services

     .  Provides 'better than copper' service quality

     .  Provides a cost efficient backhaul alternative for
        cellular / cordless networks, e.g. GSM/DECT/PHS

     .  Provides a cost-effective solution to relieve feeder
        congestion.

Deployment
Airspan AS4000 systems may be deployed either stand-alone or in conjunction with
other access technologies, and are currently operational in more than 30
operators' networks world-wide.

The CT equipment is modular in design, which allows a high degree of flexibility
for provision of multiple services, for cost effective initial provisioning, and
for easy system expansion. The modular nature of the equipment also enables fast
installation and maintenance, and minimises spares inventories.

The design of the subscriber units enables fast installation by a non-specialist
workforce.

The following pictures show examples of AS4000 equipment and deployments.

System Architecture
The following diagram shows the various elements in an Airspan AS4000
deployment.

Note that the CT sites are usually at remote locations (chosen for their radio
coverage) and the traffic is then backhauled to the switch using point-to-point
radio or fibre links.

In "Demand Assigned" (DA) operation the addition of an "Access Concentrator"
(AC) provides the traffic concentration functions and allows flexible
interfacing to the host switching network. This is normally located at the
switch site and allows the traffic from multiple CTs at a number of separate
sites to presented on unified interfaces to the switch.

The following diagram shows the DA architecture:
