supplied by ADC and incorporated into the Products, or the acts of ADC or
ADC's breach of this Agreement provided that such defects in such components
do not result from defects in the Products. In the event any claim covered by
this indemnity is asserted against either party, the other party shall
provided reasonable cooperation and assistance in the defense thereof and the

action.

</TABLE>

"Market Price" means: the end user price recorded by IWC and ADC for their
respective end-user (operator) sales accounts, by geographic region (Europe,
Asia-Pacific and North America.).

Average sales over the preceding three months will be used to determine the
"market" price.

Pricing will be reviewed and modified as necessary on a quarterly basis.. In
cases where special circumstances dictate a greater than normal discount from
list for an end-user (such as when an operator elects to make an equity
investment in conjunction with his product purchase arrangement) those
transactions will be excluded from the calculation of "average"; likewise if
ADC has a special case requiring an usual discount, then INTERWAVE will
cooperate and share the pain in terms of margin impact.

Depending on market price erosion over time, INTERWAVE and ADC reserves the
right to re-negotiate the ADC discount.

                             PRODUCT CHANGE NOTICES

INTERWAVE may, at any time, make changes to the Products or modify the
drawings and specifications relating thereto, or substitute Products of later
design to fill an order (hereinafter referred to as "Product Change"),
provided that any such Product Change, under normal and proper use, does not
affect form, fit or function of the Products or the interchangeability of the
Products with other Products, and that INTERWAVE notifies ADC in writing
thereof as soon as practicable. In the event any Product Change affects form,
fit or function of the Products, INTERWAVE shall notify ADC in writing
thereof prior to any planned change, except Class D Changes - non Customer
Affecting. In the event ADC may reject the planned change and so notifies
INTERWAVE within ten (10) days and INTERWAVE fails to reach agreement
thereon, ADC shall have the right to terminate any and all orders, in whole
or in part, for the Products affected by such change. Notwithstanding any
notice requirement above to the contrary, INTERWAVE shall immediately notify
ADC when it determines that a Class A Product Change (as defined hereinafter)
shall be made. INTERWAVE shall be authorized to make Class A Product changes
as soon as practical.

Notwithstanding any notice requirements to the contrary elsewhere in this
Agreement, all Class A Product Change Notices shall be provided, at no
charge, and forwarded in accordance with section titled "Notices". Product
Change Notices shall contain all the information set forth in Notices. If
INTERWAVE cancels a Product Change Notice, INTERWAVE must provide
notification in accordance with clause title "Notices" hereto and state the
reason for cancellation and what action, if any, is to be taken in locations
where the change may already have been implemented.

INTERWAVE shall determine the classification per the requirements of Bellcore
Technical Requirement Document TR-OPT-000209 of any proposed Product Change.
If ADC disagrees with any classification assigned by INTERWAVE, ADC shall
have the right to challenge such classification, and INTERWAVE shall, in good
faith, re-evaluate its classification. In the event that ADC and INTERWAVE
fail to reach agreement on any such classification, then ADC shall have the
right to terminate any or all Orders, in whole or in part, for Products
affected by such Product Change without penalty or obligation of any kind.

CLASS A PRODUCT CHANGE

Class A Product Changes are changes required to correct a Product deficiency
(e.g., safety or fire hazard, electrically or mechanically inoperative,
unsatisfactory operation, design defects. Product does not operate as
documented). Class A Product Changes require immediate action by INTERWAVE to
correct all affected Products, whether in the hands of INTERWAVE or ADC or
their customers including spare Products. In some cases, however, it may be
necessary to make a change to only a limited number of a particular type or
Product. (This occurs when it is necessary to correct a condition that occurs
only in certain Product combinations or with the use of certain options).
Such conditions shall be described in the Product Change Notice.

INTERWAVE shall, no later than thirty (30) days from the date of the
notification of a Class A Product Change, provide a schedule, acceptable to
ADC for promptly implementing, at INTERWAVE' expense, such changes with
respect to Products in ADC or their customer's possession. Such
implementation shall include the deinstallation, if necessary, of existing
Products and the engineering and installation of replacement or modified
Products or any additional materials.
<PAGE>

NOTICES

features, and the like.

All Products shipped to ADC after the effective date of any Class B Product
Change shall incorporate such change. Any Products shipped to ADC prior to
such date may be modified by ADC at its option and expense.

No Class B changes shall effect interoperability of the product

CLASS D PRODUCT CHANGE

Class D Product Changes are design improvements, component changes, new
features, or other minor improvements not sufficiently significant as to
require a Class B classification. Class D Product Changes are also used when
a change is required to facilitate manufacture or to effect a cost reduction
not sufficiently important to justify a Class B classification.

                          SUPPORT AND UPGRADE POLICY

1.   This policy describes the responsibilities of INTERWAVE and ADC with
     respect to hardware and software upgrades that are required to resolve
     demonstrated problems with the equipment. These are known as "problem
     fix upgrades". Hardware and software upgrades whose purpose is to
     enhance the functionality of the equipment ("feature upgrades") are
     quoted by INTERWAVE on a case-by-base basis and are not covered by this
     policy.

2.   For software problems that are reported by ADC, verified and/or
     recreated by INTERWAVE and which are fixed on a subsequent revision of
     software, INTERWAVE shall provide to ADC two (2) master copies of the
     software revision that incorporates the fix. The software will be
     accompanied by a completed "Engineering Change Request (Software)" form
     which, among other information, states the severity of the problem
     ("Class of Change") and a non-binding recommendation to ADC on the
     handling of the change in the field ("Field Effectivity Status"). The
     decision on the deployment, if any, of the software fix to one or more
     end-users in the field is the responsibility of ADC and all costs
     associated with that deployment will be borne entirely by ADC. This
     paragraph describes the totality of INTERWAVE' responsibilities which
     are limited to the provision of the two master sets of software and of
     the accompanying Engineering Change Request (ECR) notification.

3.   For hardware problems that are reported by ADC, verified and/or
     recreated by INTERWAVE and which are fixed by a hardware modification to
     the card, module or subsystem, INTERWAVE shall provide to ADC a
     completed "Engineering Change Request (Hardware)" form which, among
     other information, states the severity of the problem ("Class of
     Change"). The Class of Change defines INTERWAVE' responsibilities with
     regard to the performance of the hardware upgrade to units that are
     already installed in the field.

     a.  If the assigned Class of Change is "A", then INTERWAVE will perform
         the required hardware upgrade to effected units at no charge.
     b.  If the assigned Class of Change is "AC" or "AR", then INTERWAVE will
         perform the required hardware upgrade to effected units at no charge
         if ADC so requests in writing within thirty (30) days of receipt of
         the associated ECR.
     c.  If the assigned Class of Change is "B" or "D", then INTERWAVE will
         not upgrade any installed units at no charge. At ADC's request,
         INTERWAVE will quote such upgrades on a case-by-case basis.

     In all instances where the Class of Change obligates INTERWAVE to
     perform no-charge hardware upgrades. ADC shall request and receive a
     Return Authorization and shall promptly return all parts requiring the
     upgrade, freight prepaid to INTERWAVE' Service Department INTERWAVE
     shall have twenty (20) business days to perform the upgrade and return
     the part, freight prepaid, to ADC.

4.   For enhancements or new feature upgrades, ADC may send the Product to be
     upgraded freight prepaid to INTERWAVE' Service Department. ADC must
     issue a purchase order for the upgrade cost as specified in INTERWAVE'
     then current upgrade price list. A Return Authorization must be included
     with the Product sent to INTERWAVE. The upgraded Product will be
     returned to ADC within twenty (20) business days.

5.   Advance Replacement Service. If necessary, ADC may request an advance
     replacement exchange for the unit to be upgraded for those cases in
     which ADC can not wait the standard return period. ADC may arrange for
     this service as follows:
<PAGE>

                         -   Secure a Return Authorization for the Product to
                             be exchanged.

                         -   Issue a purchase order for the Product required
                             at INTERWAVE' then current list price plus the
                             cost of the upgrade and a $750 exchange service
                             fee.

                         -   Upon receipt of the proper purchase order.
                             INTERWAVE will ship to ADC an upgraded product
                             for exchange. Upon receipt of the Product ADC
                             should immediately return the exchanged Product
                             in the same container.

                         -   Upon receipt of the returned Product INTERWAVE
                             will issue a credit against ADCs purchase order
                             for the list price of the returned Product

If the exchanged Product is not returned within thirty (30) days ADC will be
invoiced for the Product shipped at the list price and ADC agrees to pay said
invoice due upon receipt

A. Changes which are (1) needed to correct (a) conditions which result in safety
hazards, or (b) conditions which result in non-compliance with federal
registration or radiation requirements or other federal, state or local safety
regulations or UL requirements; and (2) judged by Customer severe enough to have
to be made to all hardware in process, in stock or installed.

CLASS AC CHANGES
         Changes which are (I) needed to correct (a) inoperative electrical
         or mechanical conditions, or unsatisfactory maintenance or operating
         conditions, or (b) conditions which result in safety hazards, where
         the conditions in (a) or (b) are caused by circuit combinations or
         options which exist only on certain hardware; (2) needed to
         compensate for marginal (worse circuit) cases where the inoperative
         or unsatisfactory conditions exist on certain hardware and cannot be
         associated with specific circuit combinations or options. Such
         changes shall be made on Products in process and if requested by
         Buyer on Products in stock or returned to an authorized repair
         center.

CLASS AR CHANGES
         Changes which are needed to correct unsatisfactory electrical,
         mechanical or operating conditions, which may be allowed to exist on
         a temporary basis. Such changes shall be made to Products in
         process, except that in some cases, if Customer gives written
         consent, Products may be shipped for a period of time specified by
         Customer without incorporating the change at that time to Products
         in process. If Customer requests that such changes be made to
         Products in stock or already installed, supplier shall make such
         changes.

CLASS B - CHANGES

Changes which are sufficiently important to require their application to
Products being manufactured (as soon as reasonably possible) and/or which may
also be recommended for application to existing stock and installations in
the field. Examples of this class of changes may include, but are not limited
to:

         a) Providing new features that directly affect Product operability.

         b) Providing design improvements which result in better service
            capabilities, longer life or improved operability margins.

         c) Providing changes in design which result in important cost
            savings to Customer.

CLASS BU CHANGES
         For conditions of a mandatory nature, for example, the fulfillment
         of future federal registration or future compatibility requirement
         or for conditions of sufficient importance to be intended for
         universal application. Such changes would only be required of
         Products in process.

CLASS D CHANGES- NON-CUSTOMER AFFECTING

D. Other changes not sufficiently important to justify application to
Products being manufactured within any specified time frame and not
sufficiently important to recommend for application to existing stock and
installations in the field.

                                   EXHIBIT I

                          DIAGNOSTIC SUPPORT SERVICES

I.       INTERWAVE' RESPONSIBILITIES

         INTERWAVE will provide at prevailing rates either via annual service
         agreement or time and materials, to ADC the following support
         services to ADC during the term of this Agreement, except that
         during the warranty period, such support services shall be free of
         charge.

         A.       Dial-in Diagnostics:

                  INTERWAVE shall provide, during its principal period of
                  service (PPS), a dial-in diagnostic service which will
                  allow INTERWAVE technical support engineers remote dial-in
                  access to an End User node in order to perform on-line
                  diagnostics and problem determination. Problem
                  determination and resolution will be performed with ADC not
                  the End User. INTERWAVE will make every reasonable effort
                  to respond to service requests promptly.

         B.       Network Emergency Assistance:

                  1.  A "Network Emergency" shall be defined as the failure
                      of a previously operating INTERWAVE Product which
                      renders the Product inoperable.
                  2.  INTERWAVE will provide access to INTERWAVE technical
                      support engineers via a telephone "Hot Line" to assist
                      ADC with Network Emergencies twenty-four (24) hours a
                      day, seven (7) days a week.
                  3.  INTERWAVE reserves the right to invoice ADC at the time
                      and material rates then in effect, for support services
                      requested by ADC outside the PPS which is determined not
                      to be a Network Emergency.

         C.       "Principal Period of Support" ("PPS") means the period of 8
                  am. to 5 p.m. Pacific Time, Monday through Friday,
                  excluding INTERWAVE observed holidays.

         D.        Problem Resolution

                  For each network emergency, INTERWAVE will assign a systems
                  engineer to follow through and report status to ADC until

                      technical support representative must attend INTERWAVE'
                      training program prior to the date of any support
                      services request

                  2.  ADC shall designate in writing (by name, title, address
                      and phone number) to INTERWAVE a primary technical
                      support representative.

                      (i)  the ADC support representative shall be the
                           primary contact with INTERWAVE for all support
                           services provided hereunder.

                           representatives will be knowledgeable in the
                           support of the Products.

                      (iv) ADC may change primary and alternate technical
                           support representative(s) by issuing written
                           notice to INTERWAVE.

         B.  When use of the INTERWAVE dial-in diagnostics capability is
           requested by ADC and/or determined by INTERWAVE to be necessary:

                  1.  ADC shall insure that a telephone line is available to be
                      attached to the integral modem on the End User node.

                  2.  ADC shall obtain from the End User and be responsible for
                      all necessary authorizations for remote access by

"Market Price" means: the end user price recorded by IWC and ADC for their
respective end-user (operator) sales accounts, by geographic region (Europe,
Asia-Pacific and North America.).

Average sales over the preceding three months will be used to determine the
"market" price.

Pricing will be reviewed and modified as necessary on a quarterly basis..

In cases where special circumstances dictate a greater than normal discount from
list for an end-user (such as when an operator elects to make an equity
investment in conjunction with his product purchase arrangement) those
transactions will be excluded from the calculation of "average"; likewise if ADC
has a special case requiring an usual discount, then INTERWAVE will cooperate
and share the pain in terms of margin impact.

Depending on market price erosion over time, INTERWAVE and ADC reserves the
right to re-negotiate the ADC discount.

Note:
1.       In conjunction with a commitment purchase agreement between ADC and
         INTERWAVE, ADC shall receive an additional [***] off of the
         discounted price for the first and second year of the purchase
         agreement. For example, the first year discount for purchases
         between $ 0 - 10 M is now [***] rather than [***].

                            APPENDIX E TO EXHIBIT "A"
                   PCS 1900 BSS HIGH LEVEL MARKET REQUIREMENTS

1.  GENERAL
The purpose of this paper is to define the high level market requirements for an
initial release of PCS 1900 BSS equipment. The PCS 1900 equipment (hardware and
software) shall in general have the same functionality as the corresponding DCS
1800 products at the same time. As such this paper describes only the
differences required for the PCS 1900 BSS products.

2.  1900 MHZ FREQUENCY BAND
The PCS 1900 BSS shall use the 1900 MHz frequency band, namely 1850 to 1910 MHz
for uplink, MS to BTS and 1930 to 1990 MHz for downlink, BTS to MS, channel
numbers 512 to 812 inclusive. All equipment shall operate over the full
frequency band and be compliant and tested to JTC PCS Air interface
Specification, PN3389.

The transmitter shall meet the FCC Code of Federal Regulations, volume 47,
section 24.238. titled - `emission limits' which defines the performance at the
band edge.

3.  TRANSCODING
The system shall support the GSM/JTC approved Enhanced Full Rate (EFR) vocoder
as well as the standard Full Rate (FR) vocoder. Both coders will be required to
operate for any TRX and TRAU timeslot at any time and shall allow handover from
FR to EFR and vice versa.

The design shall (if possible) enable a software upgrade to support another
speech coder at a later date.

Due to the T1 interface only supporting 24 64 kbit/s timeslots less DSP/TRAU
boards may be needed on the T1 board for the Abis interface at the BSC.

4.  T1 INTERFACE
The interface between BTS and BSC (Abis interface) and between BSC and MSC (A
interface) shall be 1.544 Mbit/s T1 format. This shall be compliant with ITU T
G.703, ANSI T1.403-1995 and all other appropriate standards.

The interface shall be configurable to support standard super frame (SF) or
extended super frame (ESF) formats, and shall use B8ZS line coding for 64 kbit/s
clear channel capability. The line build out shall be automatically set based on
the level received from the transmission network.

All the ESF CSU/DSU functions shall be supported. This includes local and remote
loopbacks and all performance measurement statistics.

Synchronization to the T1 incoming signal needs consideration due to the
extensive use of SONET networks for delivery of T1 services which may cause
disruptions after pointer alignment changes.

5.  A INTERFACE
The A interface signaling shall use ANSI based protocol stack (MTP and SCCP) for
connection of the BSC to a MSC.

Voice traffic on the A interface shall use mu-law encoding.

6.  3 DIGIT MNC
The PCS 1900 BSS shall support the use of both a 2 or 3 digit MNC.

                                      19

<PAGE>

7.  ENVIRONMENTAL
Full NEBS (GR 63) compliance will be required for any equipment that may be
placed in any of the AT+T or RBOC central office sites. Special attention should
be made to the burn, brush fire and seismic tests and lightning protection on T1
lines for all equipment and seismic tests for indoor equipment. The bullet
proofing is not required but any outdoor equipment should be tested to verify
what can be achieved.

Outdoor equipment shall meet TA-NWT-487 but for an operating ambient temperature
of -30 to +45 degC plus a solar load of 1120 W/sq.M..

All equipment shall also meet all national and other local standards in the
U.S. and Canada.

8.  OMC-R
All workstations shall use the US country kit.

The OMC-R server shall use a T1 interface (as per section 4) to a MSC or BSC for
communication with the BSS.

The OMC-R shall provide full support of all the above functionality changes.

9.  CRAFT
The craft interface shall provide full support of all the above changes.

10. QUALIFICATION
         -        FCC part 15, part 47 and part 68
         -        UL
         -        JTC, PN 3389
         -        Bellcore GR 63 NEBS, GR1089 and TA-NWT-487
         -        Health and safety
         -        CSA
         -        Environmental, EMC etc.

11.  LABELING
The equipment shall comply with all national and local labeling requirements in
the U.S. and Canada.

12. WAIVERS
The following are areas of waivers that may be acceptable if the fully compliant
solution is overly complex, expensive or will take too long to develop.

         - If the full band solution is overly complex or expensive to implement
         it may be acceptable to change this so that two versions of the RF
         distribution card in the Wavexpress exist creating a split band. The
         target frequency coverage for the two version shall be:

         High Band     Uplink - 1864 to 1910 MHz     Downlink- 1944 to 1990 MHz
         Low Band:     Uplink - 1850 to 1896 MHz     Downlink- 1930 to 1976 MHz

         - 2 TRX Wavexpress instead of 3 TRX?

certain Amendment No. 2 dated March 30, 1998 ("Amendment No. 2") (collectively
referred to as the "Agreement").

         B. The parties now desire to amend the Agreement to revise certain
terms and conditions thereof.

         C. Unless specifically defined herein, all capitalized terms shall have

         NOW, THEREFORE, in consideration of the foregoing premises and the

deleted in its entirety and replaced with new Sections 1 (c), (d), (e), (f), (g)
and (h) as follows:

                  "(c) NATURE OF AGREEMENT. The Products delivered by INTERWAVE
that are covered by this Agreement include both hardware components (the
"Hardware") and computer software (the "Software"). Hardware and Software
hereinafter shall be referred to collectively as Products, although it is
understood ADC is not purchasing the Software, but instead is being granted the
right to use (and further sublicense the use of) the Software in accordance with
the terms and subject to the conditions set forth below. ADC shall not obtain
title to, or any proprietary rights in, such Software, except as expressly
provided below. ADC shall comply strictly with all restrictions on the use of
the Software licensed by INTERWAVE to ADC hereunder and shall require such
compliance by ADC's customers. It is hereby acknowledged and agreed that the
Software and features thereof constitute either the copyrighted property of
INTERWAVE or the proprietary trade secret information of INTERWAVE, or both.

                                     -1-

                  (d) GRANT OF LICENSE. INTERWAVE hereby grants to ADC, subject
to the performance by ADC of its obligations under this Agreement, a
non-exclusive, non-transferable world-wide license to:

                           (i) copy the Software onto Read Only Memory chips
("ROMs") or onto diskettes/CDs solely for the purposes of incorporating the
Software into Products, or for supplying such diskettes/CDs to ADC's resellers
or customers in conjunction with sales of Products; and

                           (ii) make such copies of the Software as are
reasonably necessary for the purpose of back-up and support.

                  (e) OBLIGATIONS OF INTERWAVE. As soon as practicable
hereafter, INTERWAVE shall deliver to ADC one master copy of the Software by
such means as INTERWAVE shall reasonably prescribe or as the parties shall
agree, so that ADC may copy the Software as permitted by the license granted
under Section 1 (d) above. At ADC's request, INTERWAVE shall provide ADC with
technical support and advice regarding integration of the Software into the
Products as agreed from time to time, at INTERWAVE's then-current rates and upon
INTERWAVE's then-current terms for providing the same.

                  (f)      LIMITATIONS ON LICENSE.

                           (i) The Software is licensed for use only on Products
supplied by INTERWAVE, and ADC shall not remove any pre-loaded Software or
attempt to execute the Software on any hardware other than the Hardware
purchased by ADC hereunder, with the sole exception of the OMC Software, which
INTERWAVE acknowledges may be run on workstations procured directly from the
vendor so long as such Software and work-stations are run in the overall
INTERWAVE environment. Except as expressly authorized herein, ADC may not copy
the Software or the human-readable features thereof for any purpose without
INTERWAVE's prior written consent.

                           (ii) ADC shall not attempt to decompile,
reverse-engineer or otherwise disassemble the Software. Information necessary to
achieve interoperability of the Software with independently created computer
programs is available on written request to INTERWAVE and payment to INTERWAVE
of a reasonable fee.

                           (iii) In no event shall ADC license or deliver to any
customer or third person any source code for the Software, in whole or in part,
without the prior written consent of INTERWAVE. If a customer of ADC insists on
licensing the underlying source code for interoperability and/or maintenance
purposes, ADC shall notify INTERWAVE thereof, and INTERWAVE will consider in
good faith licensing the source code to the Software directly to such customer
on such terms and conditions as INTERWAVE deems appropriate.

                  (g) RIGHT TO SUBLICENSE. ADC may sublicense the Software to
any subsequent purchaser or ADC reseller of the Products in the Territory for
use solely in connection with the

                                     -2-
<PAGE>

Products; provided that: (i) each ADC customer executes an End-User License
Agreement containing terms at least as protective of the licensor as those
contained in Exhibit F attached hereto (the "End-User License"), provided that
INTERWAVE acknowledges that ADC may add to and or modify the terms of the
End-User License so long as the foregoing requirement is met; and (ii) INTERWAVE
is given a copy of the End-User License entered into with each ADC customer
promptly following its execution or any subsequent amendment thereto.

                  (h) ADC'S OBLIGATIONS. During the term of this Agreement ADC
shall:

                           (i) use commercially reasonably efforts to enforce
against all resellers or customers that obtain the Products from ADC the
provisions of the End-User License that affect proprietary or confidentiality
rights of INTERWAVE or its licensors in the Products; and

                           (ii) inform INTERWAVE, immediately upon becoming
aware of the same, of any breach by resellers or end users of the terms of the
End-User License and take, at INTERWAVE's expense, such reasonable steps as
INTERWAVE shall request and otherwise assist INTERWAVE in enforcing the terms of
the End-User License, including, where appropriate, availing itself of actions
for seizure or injunctive relief. If ADC fails to take these steps in a timely
and adequate manner, INTERWAVE or its licensors may take them in its own or
ADC's name."

         2. AMENDMENT TO EXHIBIT F. From and after the date hereof, Exhibit F to
the Agreement is hereby deleted in its entirety and replaced with a new Exhibit
F in the form attached hereto.

         3. AMENDMENT TO SECTION 4.1. Section 4.1 is hereby deleted in its

Period"). During the Warranty Period, INTERWAVE shall take all reasonable steps
without charge to correct errors or defects in any Software and any corrections
for errors or defects shall be provided to ADC directly and/or incorporated in
subsequent updates to the Software from INTERWAVE. Such corrections may be used
and distributed by ADC as permitted by Section 1 of this Agreement. INTERWAVE
MAKES NO WARRANTS OR REPRESENTATIONS AS TO PERFORMANCE OF PRODUCTS OR AS TO
SERVICE TO ADC OR TO ANY OTHER PERSON, EXCEPT AS SET FORTH IN THIS SECTION 4.1

                                   EXHIBIT "F"

                  MANDATORY TERMS OF END-USER LICENSE AGREEMENT

ADC hereby grants to Customer, and Customer hereby accepts from ADC, an
indefinite, non-exclusive and non-transferable right to use the software
described in Section 1 below (the "Software") on the hardware described in
Section 2 below (the "Hardware"), subject to the terms and conditions specified
below (the "License").

1.       SOFTWARE

"Software" means (i) the machine-readable object code version of the computer
programs described in the Product Schedule, whether embedded on disc, tape or
other media (the "Programs"); (ii) the user manuals and documentation for the
Programs that are provided to the Customer (the "Documentation"); (iii) the
fixes, customizations or revisions of the Programs or Documentation that are
provided to Customer (the "Enhancements"); and (iv) any copy of the Programs,
Documentation or Enhancements. Nothing in this License shall entitle Customer to
receive the source code of the Programs or Enhancements, in whole or in part.

2.       HARDWARE

"Hardware" means the hardware equipment configuration identified in the
Product Schedule on which the Software is first installed or for which it is
first provided. Customer may use the Programs and Enhancements only on the
Hardware while it possesses and operates the Hardware. Any other use or
transfer of the Programs or Enhancements requires ADC's prior approval, which
may be subject to additional charges.

3.       USE

Customer may use the Software only in and for Customer's own internal purposes
and business operations. Customer shall not permit any other person to use the
Software, whether on a timesharing, remote entry or other multiple user
arrangement. Customer may not copy any of the Documentation except for internal
use. Customer may copy the Programs and Enhancements solely for archival and
back-up purposes. Customer shall reproduce all confidentiality and proprietary
notices on each of these copies and maintain an accurate record of the location
of each copy the Programs or Enhancements. Customer may not otherwise copy,
translate, modify, adapt, decompile, disassemble or reverse engineer the
Software, except as and to the extent specifically permitted under applicable
law.

4.       CONFIDENTIALITY

Customer acknowledges that the Software embodies confidential and proprietary
information developed or acquired by or licensed to interWAVE Communications
International, B.V., a company organized under the laws of The Netherlands
("interWAVE"). Customer shall take all reasonable precautions necessary to
safeguard the confidentiality of the Software, including (i)

                                    -6-
<PAGE>

those taken by Customer to protect Customer's own confidential information and
(ii) those which ADC may reasonably request from time to time. Customer shall
not allow the removal or defacement of any confidentiality or proprietary notice
placed on the Software. If an unauthorized use or disclosure occurs, Customer
shall immediately notify ADC and take, at Customer's expense, all steps which
may be available to recover the Software and to prevent their subsequent
unauthorized use or dissemination. Customer shall have no confidentiality
obligation with respect to any portion of the Software that (i) Customer
independently developed before receiving the Software from ADC, (ii) Customer
lawfully obtained from a third party under no confidentiality obligation or
(iii) became available to the public other than as a result of an act or
omission by Customer or any of its employees or consultants.

5.       OWNERSHIP

All patents, copyrights, trademarks, service marks, trade secrets and other
proprietary rights in or related to the Software are and shall remain the
exclusive property of ADC or its licensors, whether or not specifically
recognized or perfected under local applicable law. Customer shall not take any
action that jeopardizes ADC's or its licensors' proprietary rights or acquire
any right in the Software, except the limited use rights specified in this
License. ADC or its licensors shall own all rights in any copy, translation,
modification or adaptation of, or derivative work based on, the Software.
Customer shall obtain, at ADC's request, the execution of any instrument that
may be appropriate to assign these rights to ADC or its licensors or perfect
these rights in ADC's or its licensor's name.

6.       INFRINGEMENT

If an action is brought against Customer claiming that the Software supplied by
ADC infringes a patent, copyright, trade secret or trade mark within the country
of installation (the "Territory"), ADC shall defend Customer, but only if: (i)
Customer notifies ADC promptly upon learning that the claim might be asserted;
(ii) ADC has sole control over the defense of the claim and any negotiation for
its settlement or compromise; and (iii) Customer takes no action that, in ADC's
reasonable judgment, is contrary to ADC's interest. If a claim described in this
Section may be or has been asserted, Customer shall permit ADC or its licensors,
at ADC's option, to: (i) procure the right to continue using the Software; (ii)
replace or modify the Software to eliminate the infringement while providing
functionally equivalent performance; or (iii) accept the return of the Software
and refund to Customer the amount actually paid to ADC for such Software, less
depreciation based on a 5-year straight-line depreciation schedule. ADC shall
have no indemnity obligation to Customer under this Section if the infringement
claim results from: (i) a correction or modification of the Software not
provided by ADC; (ii) the failure to promptly install an Enhancement; or (iii)
the combination of the Software with other items not provided by ADC.

7.       DISCLAIMER

Customer acknowledges that the warranties, conditions, guarantees or
representations granted with respect to the Software, if any, are or shall be
binding only on ADC. EXCEPT AS EXPRESSLY PROVIDED HEREIN, NEITHER ADC NOR ITS
LICENSORS GRANT

                                -7-
<PAGE>

CUSTOMER ANY WARRANTY, GUARANTEE, CONDITION OR REPRESENTATION WITH RESPECT TO
THE SOFTWARE, AND ADC AND ITS LICENSORS DISCLAIM ALL IMPLIED WARRANTIES,
INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR PARTICULAR PURPOSE. Any claim for breach of warranty, guarantee,
condition or representation, whether express or implied, may be brought solely
against ADC, except only as and to the extent otherwise specifically permitted
under applicable law, despite the foregoing disclaimer.

8.       EXCLUSION AND LIMITATION

UNDER NO CIRCUMSTANCES SHALL ADC OR ITS LICENSORS BE LIABLE FOR ANY
CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR INCIDENTAL DAMAGES OR LOST
PROFITS, WHETHER FORESEEABLE OR UNFORESEEABLE, BASED ON CUSTOMER'S CLAIMS OR
THOSE OF ITS CUSTOMERS (INCLUDING, BUT NOT LIMITED TO, CLAIMS FOR LOSS OF DATA,
GOODWILL, USE OF MONEY OR USE OF THE PRODUCTS, INTERRUPTION IN USE OR
AVAILABILITY OF DATA, STOPPAGE OF OTHER WORK OR IMPAIRMENT OF OTHER ASSETS),
ARISING OUT OF BREACH OR FAILURE OF EXPRESS OR IMPLIED WARRANTY, BREACH OF
CONTRACT, MISREPRESENTATION, NEGLIGENCE, STRICT LIABILITY IN TORT OR OTHERWISE.
IN NO EVENT SHALL THE AGGREGATE LIABILITY WHICH ADC OR ITS LICENSORS MAY INCUR
IN ANY ACTION OR PROCEEDING EXCEED THE TOTAL AMOUNT ACTUALLY PAID BY CUSTOMER
FOR THE SPECIFIC ITEM THAT DIRECTLY CAUSED THE DAMAGE. THIS SECTION SHALL NOT
APPLY ONLY WHEN AND TO THE EXTENT THAT APPLICABLE LAW SPECIFICALLY REQUIRES
LIABILITY, DESPITE THE FOREGOING EXCLUSION AND LIMITATION.

9.       TERMINATION

ADC may terminate this License, upon reasonable notice and without judicial or
administrative resolution, if (i) Customer or any of its employees or
consultants breach any term or condition hereof, (ii) Customer permanently
discontinues the use of the Software, or (iii) Customer becomes insolvent or
enters into bankruptcy, suspension of payments, moratorium, reorganization or
any other proceeding that relates to insolvency or protection of creditors'
rights. Upon the termination of this License for any reason, all rights granted
to Customer hereunder shall cease, and Customer shall promptly: (i) purge the
Programs and Enhancements from the Hardware and all of Customer's other computer
systems, storage media and other files; (ii) destroy the Software and all copies
thereof; and (iii) deliver to ADC an affidavit which certifies that Customer
have complied with these termination obligations. The provisions of Sections 4,
5, 7, 8 and 10 shall survive the termination of this License.

10.     U.S. EXPORT RESTRICTIONS

Customer acknowledges that the Software and all related technical data are
subject to export controls under the U.S. Export Administration Regulations.
Customer may not re-export or disclose the Software or any related technical
data, or any direct product thereof, unless

                                    -8-
<PAGE>

Customer has obtained an appropriate authorization from ADC, its licensors and
the U.S. Commerce Department.

11.      INSPECTION

During the term of this License, ADC or its designees may, upon prior notice to
Customer, inspect the files, computer processors, equipment and facilities of
Customer during normal working hours to verify Customer's compliance with this
License. While conducting such inspection, ADC or its designees shall be
entitled to copy any item that Customer may possess in violation of this
License.

12.      BENEFICIARIES

The provisions of this License are intended to inure to the benefit of ADC, its
licensors and their related persons. If Customer breaches any of these
provisions, ADC and its licensors shall be entitled to enforce this License
directly against Customer, whether in ADC's or its licensors' own names.
Customer acknowledges that ADC executes the document setting forth this License
as principal on its own behalf and, exclusively to accept or otherwise perfect
its licensors' rights against Customer, as agent on behalf of such licensors.

13.      ASSIGNMENT

Customer shall not assign, delegate or otherwise transfer this License or any of
its rights or obligations hereunder, in whole or in part, without ADC's prior
approval. ADC may in its sole discretion assign, delegate or otherwise transfer
this License or an of its rights or obligations hereunder, in whole or in part,
without Customer's prior approval.

14.      DISPUTE RESOLUTION

Either party may, without inconsistency with this Agreement, seek from a court
of competent jurisdiction any interim or provisional relief that may be
necessary to protect the rights or property of that party, pending the
establishment of the arbitral tribunal or pending the arbitral tribunal's
determination of the merits of the controversy.

15.      MISCELLANEOUS

Any waiver or modification of this License shall not be effective unless
executed in writing and signed by ADC. This License shall bind Customer's
successors-in-interest. If any provision of this License is held to be
unenforceable, in whole or in part, such holding shall not affect the validity
of the other provisions of this License, unless ADC in good faith deems the
unenforceable provision to be essential, in which case ADC may terminate this
License effective immediately upon notice to Customer. No failure or delay on
the part of ADC to exercise any right or remedy specified herein shall be
construed as a waiver of such right or remedy. This License constitutes the
complete and entire statement of all conditions and representations with respect
to its subject matter and supersedes all prior writings or understandings.

2        GRANT OF RIGHT AND RELEASE

2.1    Subject to the terms and conditions of this Agreement, Nortel and NMC, to
       the extent of their legal right so to do, hereby grant to interWAVE a
       personal, non-transferable, non-assignable, indivisible, non-exclusive,
       worldwide license to make, use, lease and sell Microcellular
       Infrastructure Products under the Nortel Infrastructure Patents, and a
       personal, non-transferable, non-assignable, indivisible, non-exclusive,
       worldwide license to make, use, lease and sell Microcellular
       Infrastructure Products under the Sublicensed Patents.

2.2    Subject to the terms and conditions of this Agreement, Nortel and NMC, to
       the extent of their legal right so to do, hereby grant to interWAVE a
       personal, non-transferable, non-assignable, indivisible, non-exclusive,
       worldwide license to make, use, lease and sell Microcellular
       Infrastructure Products under such Nortel and NMC patents and patent
       applications existing as of the Effective Date, or issued or granted or
       acquired during the term of the OEM Agreement, as relate to the Technical
       Information.

2.3    Subject to the terms and conditions of this Agreement, Nortel and NMC, to
       the extent of their legal right so to do, hereby grant to interWAVE a
       personal, non-transferable, non-assignable, indivisible, non-exclusive,
       worldwide license to make, use, lease and sell Microcellular
       Infrastructure Products under such other Nortel or NMC patents and patent
       applications existing as of the Effective Date, or issued or granted or
       acquired during the term of the OEM Agreement, as relate to the practice
       of the GSM standards.

2.4    The limitations on the scope of the license and rights granted hereunder
       arising from the definitions of "Microcellular Infrastructure Products"
       and "Microcellular Public Radio Systems" (the "Definitions") are intended
       by the Parties to distinguish microcellular wireless infrastructure
       products from other wireless products and to reflect the capacities and
       specifications of the Microcellular Infrastructure Products making up the
       interWAVE product line at the Effective Date. The Definitions shall be
       subject to review by the Parties on a yearly basis from the Effective
       Date. The Parties agree to negotiate in good faith with a view to
       revising the scope of the Definitions to reflect the evolution of the
       microcellular infrastructure technology and the demands of the
       microcellular infrastructure marketplace. In any event, the scope of the
       license shall include at a minimum the products Nortel will source under
       the OEM Agreement and any products planned in the development agreements
       arising under the Technical Information Agreement. Where there is written
       agreement among the Parties, the agreed upon revised Definitions shall
       replace the current definitions for the purposes of the license granted
       hereunder. Notwithstanding the above, in the event that a significant
       technology change has impacted the microcellular infrastructure market,
       either party may request the other party on 60 days notice to meet and
       vary the Definitions based on this change. The Parties agree to negotiate
       this required definition change in good faith.

2.5   interWAVE shall have no right to grant sublicenses under the above
      licenses, but such limitation shall not be construed as limiting
      interWAVE's rights to directly and indirectly distribute, and allow
      its customers and transferees to use, Microcellular Infrastructure
      Products for their intended purposes. Such licenses also include the
      right to have Microcellular Infrastructure Products made by another
      manufacturer for the use, lease or sale by interWAVE, but only when
      of both the following conditions are met:

       (a)    the designs, specifications and working drawings for the
              manufacture of said Licensed Products are furnished by
              interWAVE; and

       (b)    said designs, specifications and working drawings are in
              sufficient detail that no material modification by the
              manufacturer is required other than adaptation to the
              production processes and standards normally used by the
              manufacturer which changes the characteristics of the
              products only to a negligible extent.

2.6   Nortel and NMC hereby release interWAVE, and all purchasers and users
      of Microcellular Infrastructure Products, from all claims, demands and
      rights of action which Nortel or NMC may have on account of any
      infringement or any alleged infringement of any of the patents licensed
      in this Section 2 by reason of the manufacture, use, lease or sale of
      Microcellular Infrastructure Products prior to the Effective Date by
      interWAVE.

3     TERM OF LICENSE

3.1   Subject to the terms and conditions of this Agreement, all patent
      licenses herein granted shall commence on the Effective Date, or when
      letters patent are issued or granted if subsequent thereto, and shall
      continue for a term of one year at which time they shall be subject to
      renewal for a further term of one year with the consent of all Parties,
      provided that the consent of Nortel and NMC shall not be required unless
      during the preceding one year term any of the termination provisions of
      section 5 have been held to be unenforceable for any reason. Except as
      aforesaid, such annual renewals shall continue for the entire duration
      of the patent rights under which such licenses are granted.

4     PRICE

4.1   The price to be paid by interWAVE to Nortel and NMC for the license and
      other rights granted herein shall be US$ 1 million, to be allocated 90
      percent to NMC and 10 percent to Nortel.

                                      7

<PAGE>

4.2   Upon interWAVE's payment of the price set forth in Section 4.1, the
      licenses and rights granted to interWAVE in Section 2 shall thereafter
      be considered paid-up and royalty-free.

5     ASSIGNMENT AND CHANGE OF CONTROL

5.1   In the event that this Agreement is to be assigned or transferred by
      interWAVE, whether by way of merger, amalgamation, consolidation,
      reorganization, assignment, transfer, operation of law or otherwise
      ("Assignment") to a third party (the "Assignee") interWAVE shall, at
      least thirty (30) days prior to Assignment, provide written notice of
      such Assignment to the other Parties.

5.2   In the event of an Assignment, Nortel and NMC may, without any delay,
      by written notice, terminate this Agreement and all licenses and rights
      granted therein.

5.3   Notwithstanding section 5.2, provided that:

       (a)    the Assignee is not a Competitor of Nortel, as defined in
              section 5.9 below;

       (b)    interWAVE transfers substantially all of its assets to the
              Assignee, and the Assignee with whom interWAVE merges,
              amalgamates, consolidates or reorganizes thereby becomes the
              successor to the business of interWAVE;

       (c)    the financial condition of the Assignee as of the date of such
              assignment is not substantially worse than the financial
              condition of interWAVE as of the Effective Date of this
              Agreement; and

       (d)    such Assignee agrees in writing to Nortel (the
              "Acknowledgment") that it has assumed all obligations of
              interWAVE hereunder and that it shall be bound by the terms
              and conditions of this Agreement,

      Nortel and NMC shall grant to the Assignee licenses, similar in scope
      to those granted under this Agreement, for the manufacture, use, lease,
      and sale of Microcellular Infrastructure Products as defined and limited
      by the Definitions as they exist under this Agreement at the date
      immediately prior to the Assignment. Such license shall subsist only in
      respect of a level of sales of such Microcellular Infrastructure Products
      by such Assignee after such acquisition which does not materially exceed
      the level of such sales by the acquired entity immediately prior to such
      acquisition to be adjusted upwards on a yearly basis in accordance with
      normal growth rates in the industry.

5.4   In the event a third party (the "Acquiror") is to acquire a controlling
      interest (controlling not necessarily requiring greater than fifty
      percent (50%)) or a major

                                      8

<PAGE>

      equity participation in interWAVE ("Change of Control"), interWAVE
      shall, at least thirty (30) days prior to the Change of Control, provide
      written notice of such a change of control to Nortel.

5.5   In the event of a Change of Control, Nortel and NMC may, without any
      delay, by written notice, terminate this Agreement and all licenses and
      rights granted therein.

5.6   Notwithstanding the provisions of section 5.5, provided that the
      Acquiror is not a Competitor of Nortel, as defined in section 5.9 below,
      Nortel and NMC shall grant to interWAVE licenses, similar in scope to
      those granted under this Agreement, for the manufacture, use, lease, and
      sale of Microcellular Infrastructure Products as defined and limited by
      the Definitions as they exist under this Agreement at the date
      immediately prior to the Change of Control. Such licenses shall subsist
      only in respect of a level of sales of such Microcellular Infrastructure
      Products by interWAVE after such acquisition which does not materially
      exceed the level of such sales by interWAVE immediately prior to such
      acquisition to be adjusted upwards on a yearly basis in accordance with
      normal growth rates in the industry.

5.7   Where Nortel and NMC elect to terminate and not renew this Agreement
      under any of the provisions of Section 5 ("Termination"), Nortel and NMC
      shall refund to interWAVE, in either $US dollars or interWAVE shares at
      Nortel's option, an amount calculated in accordance with the provisions
      of Schedule E. Notwithstanding the foregoing, Nortel shall pay the refund
      in cash if the Fair Marker Value (in accordance with the principles
      articulated in Section 3.4(d)(iv)(d) of interWAVE's Bye-Laws) of one
      share of interWAVE Series G Preferred Stock is less than six dollars and
      six cents ($6.06) per share.

5.8   In the event a third party acquires a controlling interest (controlling
      not necessarily requiring greater than fifty percent (50%) interest) in
      interWAVE, resulting in the termination of the OEM Agreement in
      accordance with the provisions of the OEM Agreement, interWAVE shall
      grant to Nortel a personal, non-exclusive, non-assignable, world-wide
      license under all existing interWAVE patents and patent applications
      relating to Microcellular Public Radio Systems, such license extending
      for the full term of the applicable patents and applications and bearing
      a royalty of no greater than one percent (1%) of the net sales by Nortel
      of products covered by the claims of such patents and such applications
      when they issue as patents.

5.9   For the purpose of this section a "Competitor of Nortel" means any
      person with whom Nortel or NMC competes and which has greater than two
      percent marketshare in the wireless telecommunication infrastructure
      products market. Notwithstanding the foregoing, a person shall not be
      deemed to be a Competitor of Nortel simply by virtue of any competition
      arising solely from its acquisition of the business of interWAVE. Nortel
      shall, from time to time, upon request from and in consultation with
      interWAVE, provide interWAVE with a current list of

                                      9

<PAGE>

      Competitors of Nortel, and interWAVE shall be entitled to rely on such
      list for the purposes of this section until the later of:

              (i)   one hundred and eighty (180) days from the date of issued
                    by Nortel; or

              (ii)  the issuance of a revised list by Nortel.

5.10  Notwithstanding any assignment or Change of Control, the Parties hereto
      shall remain liable for their respective obligations hereunder.

6     MISCELLANEOUS PROVISIONS

6.1   Nothing contained in this Agreement shall be construed as:

       (a)    requiring the filing of any patent application, the securing
              of any patent or the maintaining of any patent in force;

       (b)    a warranty of representation by Nortel, or an admission by
              interWAVE, as to the validity or scope of any Nortel
              Infrastructure Patent, Sublicensed Patent or other Nortel patent;

       (c)    a warranty of representation that any manufacture, sale, lease
              or use will be free from infringement of patents other than those
              under which and to the extent to which licenses are in force
              hereunder;

       (d)    an agreement to bring or prosecute actions or suits against
              third parties for infringement;

       (e)    an obligation to furnish any manufacturing or technical
              information or assistance;

       (f)    conferring any right to use, in advertising, publicity or
              otherwise, any name, trade name or trademark, or any contraction,
              abbreviation or simulation thereof; or

       (g)    conferring by implication, estoppel or otherwise upon either
              Party any license or other right under any patent, except the
              licenses and rights expressly granted herein.

6.2   In the event of an enforceable decision or directive declaring invalid
      an essential part of this Agreement, without which this Agreement would
      not have been entered into, this Agreement may, at the option of any
      Party, be terminated upon the giving of notice to the other Parties. Save
      as before set forth, in the event that any term,

                                      10

<PAGE>

      clause, provision or condition of this Agreement shall be similarly
      adjudged invalid for any reason whatsoever, such invalidity shall not
      affect the validity or operation of any other term, clause, provision
      or condition and such invalid term, clause, provision or condition shall
      be deemed to have been deleted from this Agreement.

6.3   In the event interWAVE commits any act of bankruptcy, or compounds with
      its creditors; or a petition or receiving order in bankruptcy is
      presented or made against interWAVE; or a petition for an administration
      order is presented in relation to interWAVE; or a resolution or petition
      to wind up interWAVE (other than for a legal reconstruction,
      reorganization or amalgamation) or a receiver or administrative receiver
      is appointed; and such act or petition is not cured, dismissed, or
      withdrawn within sixty (60) days thereafter; or interWAVE ceases to carry
      on business, Nortel may, without any delay, by notice, terminate this
      Agreement.

6.4   Any and all notices and other information to be given by one of the
      Parties to the other shall be deemed sufficiently given when forwarded by
