                             Distributor Agreement
                             ---------------------

This Distributor Agreement (the "Agreement") is made effective as of the 31st
day of March, 2000 (the "Effective Date"), by and between Airspan Networks
Incorporated, a company incorporated under the laws of the State of Washington
having its principal office at 777 108th Avenue NE, Suite 1895, Bellevue,
Washington 98004 ("Airspan") and GLS LLC, ("Distributor") a limited liability
company incorporated under the laws of the State of South Dakota having its
principal office at 501 Fourth Street, Sergeant Bluff, IA 51054.

                                  WITNESSETH:

WHEREAS, Airspan is engaged in the design and manufacture of various
telecommunications product lines, including, among others, those product lines
more completely described in Schedule I hereto (the product lines described in
Schedule I, as from time to time amended in accordance with the provisions of
this Agreement, are hereinafter called the "Airspan Products") the hardware
components thereof are sometimes referred to separately as "Equipment," the
software components thereof are sometimes referred to separately as "Software"
as defined in Section 11.1, and an arrangement of Equipment which, when
interfaced with Software, is operable to perform predetermined functions, is
referred to as a "System");

WHEREAS, Distributor is engaged in the promotion of sales of telecommunications
products; and

WHEREAS, Airspan desires to appoint Distributor as a Distributor for the Airspan
Products for the territory described in Schedule II hereto (the "Territory").

NOW, THEREFORE, in consideration of the mutual promises herein contained, it is
hereby agreed as follows:

1.   APPOINTMENT.
     -----------

       1.1  Subject to the provisions of this Agreement, Airspan hereby appoints
Distributor as an independent, exclusive distributor to assist Airspan in
marketing the Airspan Products to customers in the Territory, and Distributor
hereby accepts such appointment as of the Effective Date of this Agreement.
Distributor's appointment as a distributor of the Airspan Products grants to
Distributor only a license to resell the

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

                                     Page 1
<PAGE>

Airspan Products to Distributor's customers in the Territory, and does not
transfer any right, title, or interest in any of the Airspan Software to
Distributor.

     1.2  Distributor's relationship to Airspan is that of an independent
contractor, and nothing in this Agreement shall constitute Distributor as the
agent or employee of Airspan.  Distributor shall have no authority to accept any
order or make any offer (except as herein stated), or execute any instrument or
make any commitment on behalf of Airspan.  Specifically, without in any way
limiting the generality of the foregoing, Distributor agrees not to make any
representation, guarantee, or warranty on Airspan's behalf concerning the
Airspan Products, but will refer customers to Airspan's printed literature.
Nothing contained in this Agreement is to be construed as a limitation or
restriction upon Airspan in the sale or other disposition of any of its products
to any person, firm, or corporation inside or outside of the Territory. Airspan
will pay no commissions under this Agreement.  Distributor's compensation is to
be obtained solely by the difference between the price Distributor pays to
Airspan and the price Distributor charges its customers. The parties also
acknowledge that this Agreement is not intended to create a joint venture or
partnership between Airspan and Distributor.

       1.3  Distributor will use its best efforts to maintain and support the
Airspan Products within the Territory by devoting such attention, time, and
effort as may be reasonably necessary to fully develop the available market
potential.  During the term of this Agreement, and for a period of three (3)
months following the expiration or termination of this Agreement, Distributor
agrees that neither it nor any organization or entity controlled or directed by
it will, without Airspan's prior, written consent, represent a manufacturer or
supplier of products similar in design or performance to or which are of such a
nature as to be competitive with any products contained in the Airspan Products,
nor will Distributor market or otherwise promote the sale of such products.
Distributor will give Airspan thirty (30) days' prior, written notice of each
new potential representation role being considered by Distributor, and
Distributor will not undertake such representation without Airspan's prior,
written consent, such consent not to be unreasonably withheld. Except as
provided above, in no event will Airspan consent to Distributor's consultation
for or representation of a manufacturer or supplier, which is directly or
indirectly, a competitor of Airspan.

       1.4  Distributor shall maintain a place of business at the location
specified in Section 21.10 where Distributor can be contacted by Airspan,
customers, and prospective customers during regular business hours with a
permanent mailing address and an accessible cellular telephone, and will provide
Airspan with written notice promptly upon any change in address.  Distributor
agrees to assume all of the expenses of this place of business, including rent,
stenographic services, and all other expenses except as specifically assumed in
writing by Airspan.

       1.5  Airspan will provide Distributor with such commercial and technical
assistance and training as may reasonably be necessary, in Airspan's sole
judgment, to enable Distributor to effectively carry out its activities under
this Agreement and, in connection therewith, to provide such sales promotional
materials, as Airspan may deem appropriate.  Airspan will provide such technical
support as is reasonable and necessary to maintain the product line as a viable
competitor in the market.

     and separate Agreement, such changes may be implemented in the future by
     Distributor, with the assistance of Airspan.

     writing. In the event of a conflict between the terms and conditions of
     this Agreement and of any Purchase Order issued hereunder, or if the
     Purchase Order does not reference the terms and conditions of this
     Agreement, the terms and conditions of this Agreement shall control.

<PAGE>

     Airspan warrants that during the term of this Agreement, the prices at
     which Airspan sells to Distributor products supplied under this Agreement
     shall be no less favorable to the Distributor than those prices at which
     Airspan sells, at substantially the same time in the United States, similar
     products and pursuant to similar terms and conditions as those by which
     Airspan sells Products to the Distributor under this Agreement.  Products
     shall only be deemed similar if they provide like functionality.  The terms
     and conditions shall only be deemed similar if the product is supplied
     pursuant to an agreement or arrangement of similar duration and commitment,
     provides for similar warranties and after service commitments, involves
     similar spare part and support commitments, has the same payment and other
     financial terms, and otherwise has similar terms and conditions.

          6.2  The Contract Price is shown in Schedule IV and shall include
     applicable duties, taxes or imposts, including all export or import duties.
     Sales taxes and contractor's excise taxes shall be itemized on all Purchase
     Orders.  The parties agree that the Contract Price in Schedule IV shall be
     firm for a minimum period of twenty-four (24) months from the Effective
     Date. After the above period of twenty-four (24) months, Exhibit B may be
     revised by Airspan giving thirty (30) days written notice to Distributor.

     7.  PAYMENT TERMS.

          7.1  Airspan will issue an invoice (the "Invoice") to Distributor in
     accordance with the payment terms below. The Invoice specifically will
     identify the Equipment, Software, or other items shipped, and the Contract
     Price of such items.  Any Installation Services or other services provided
     by Airspan will be invoiced separately following completion of such
     services.  The Invoice also shall state the total due to Airspan from
     Distributor (the "Invoice Total"), which shall include the Contract Price,
     and any applicable taxes, duties, and other fees due pursuant to Section 6
     of this Agreement. Payment of the Invoice Total is due (without any right
     of set-off) Net forty-five (45) days after the date of invoice.

          7.2  If Distributor disputes any invoice or part thereof, Distributor
     must notify Airspan in writing within twenty-five (25) days of the invoice
     date giving details of the reason for such dispute.

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

                                     Page 8
<PAGE>

     Distributor and Airspan agree to work together in good faith to resolve the
     dispute as quickly as possible. Distributor may withhold payment of such
     disputed amounts until resolution of the dispute. Any parts of the invoice
     not under dispute shall be paid net forty-five (45) days after the date of
     invoice. On resolution of the dispute, Distributor shall immediately pay
     any amounts due in full.

          7.3  Distributor will make payment by wire or telegraphic transfer to
     the bank account set forth below or, on receipt of written notification
     from Airspan, to another designated bank within the United States.

     Bank:            Seafirst Bank, 10555 N.E. 8th, Bellevue, WA98004, USA.
     Account name:    Airspan Networks Inc.
     Account number:  68777507
     Routing Number:  125 - 0000 - 24
     Further instructions: "Reference (Distributor's name), Purchase Order
     number, Payment of Invoice number"

     Payment will be deemed to have been made upon receipt of funds in Airspan's
     bank.

     7.4  If the cost to Airspan of performing this Agreement increases as a
     result of any change to the law or increase in import duty or freight duty,
     Airspan may, at any time, add such increase to the Contract Price by
     notifying Distributor in writing of such increase.

8.   DELIVERY, TITLE AND RISK OF LOSS.

     8.1  All Equipment and Software will be delivered by Airspan CIP (as
     defined in Incoterms 2000) to an airport in South Dakota that completes
     international customs clearances and shipped to a location within the city
     limits of the above arrival airport, such airport and delivery location are
     to be agreed upon in writing by the parties for each Purchase Order.
     Airspan will be responsible for and pay all packing, shipping, freight, and
     insurance charges to the agreed upon location within the city limits. If
     requested by Distributor, Airspan may arrange for shipment to be made to
     Distributor's identified warehouse facilities or freight forwarder outside
     of the city limits, subject to approval in writing by Airspan and agreement
     to any additional charges in advance of shipment.  Unless specified in the
     Purchase Order, Airspan will select the mode of shipment and the carrier.

     In this Agreement, "Incoterms" means the most recent international rules
     for the interpretation of trade terms published by the International
     Chamber of Commerce as in force on the Effective Date.  Unless the context
     otherwise requires, any term or expression which is defined in or given a
     particular meaning by the provisions of the Incoterms shall have the same
     meaning in this

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

                                     Page 9
<PAGE>

     Agreement, but if there is any conflict between the provisions of the
     Incoterms and this Agreement, the latter shall prevail.

     8.2 All risk of loss or damage to the Equipment and Software will pass to
     Distributor on collection by the freight forwarder from Airspan. However,
     Airspan will insure the Equipment against loss or damage in transit to the
     agreed to location as set forth in the Purchase Order within the city
     limits of the arrival airport as set forth in Paragraph 8.1.

     8.3 Title to the Equipment shall pass to Distributor on collection by the
     freight forwarder from Airspan.

     8.4  If Distributor has any Airspan owned Equipment in its possession:

     a.   Distributor shall ensure that Equipment is clearly marked as the
     property of Airspan, and if asked, shall inform any third parties that the
     Equipment is the property of Airspan;

     b.   Distributor shall not purport to create any security, mortgage, lien
     or pledge over the Equipment, or otherwise deal with the Equipment without
     Airspan's written consent;

     c.   In the event of any threatened seizure of the Equipment by any third
     parties, and on termination or expiration of this Agreement, or any
     Contract made pursuant to it, Airspan shall have the right, without
     prejudice to any other remedy, to enter without prior notice any premises
     and to repossess and take away or otherwise deal with the Equipment.

     8.5  The Software shall at all times remain the exclusive property of
     Airspan, subject to the uses provided herein.

     8.6  Unless Distributor clearly advises Airspan to the contrary in
     writing, Airspan may make partial deliveries on account of Purchase Orders.
     Delay in delivery of any installment shall not relieve Distributor of its
     obligation to accept said installment, provided that said delay does not
     exceed sixty (60) days from Airspan's scheduled ship date and unless
     Distributor has clearly advised Airspan to cancel the delayed installment
     in writing at least fifteen (15) days prior to its revised planned shipment
     date or its actual shipment date by Airspan.

     8.7  Airspan will use reasonable efforts to meet Distributor's requested
     delivery schedules for Equipment and Software, but Airspan reserves the
     right to refuse, or delay delivery to Distributor when Distributor's credit
     is impaired,

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

                                    Page 10
<PAGE>

     when Distributor is delinquent in payments or fails to meet other credit or
     financial requirements reasonably established by Airspan, or when
     Distributor has failed to perform its obligations under this Agreement.

     8.8  Should orders for Equipment and Software exceed Airspan's available
     inventory, Airspan will allocate its available inventory and make
     deliveries on a basis that Airspan deems equitable, in its sole discretion,
     and without liability to Distributor on account of the method of allocation
     chosen or its implementation.  In any event, Airspan shall not be liable
     for any direct, indirect, consequential, or special losses or damages
     (including, but not limited to, loss of income or profit and loss of data)
     that may be suffered by the Distributor or by any other person for failure
     to deliver or for any delay or error in delivery of Equipment or Software
     for any reason whatsoever.

     9.1  Distributor acknowledges Airspan's exclusive right, title, and
interest in and to any trademarks, trade names, logos and designations which
Airspan may at any time have adopted, used, or registered in the United States
of America and in the Territory (the "Trademarks"), and will not at any time do

with any reference to the Trademarks, Distributor shall not in any manner

courts or before the administrative agencies of the Territory or otherwise, and
to make promptly available to Airspan, its Distributors, and attorneys all of
Distributor's files, records, and other information pertaining to the
advertising, promotion, and sale of the Airspan Products.  All assistance
requested by Distributor in this paragraph shall be at AIRSPAN's expense.  This
Expense includes costs, attorneys' and consultants' fees, and reimbursement of
time spent by officers, agents and employees of Distributor.

     9.7  Distributor agrees and undertakes that it will not at any time,
whether during the term of this Agreement or after its expiration or
termination, adopt, use, or register without Airspan's prior, written consent
any work or symbol or combination thereof which is similar to any of the
Trademarks.

     9.8 In the advertising and sale of Airspan Products, Distributor may use
the Trademarks in relation to those Airspan Products.  Distributor will not make
or permit the alteration or removal of any tags, labels, or other identifying
marks placed by Airspan on Airspan Products.  Distributor will not use or give
any third party permission to use the Trademarks. Distributor will not use, or
give any third party permission to use, the names "Airspan Communications Ltd.",
"Airspan Networks Incorporated", "ACL", "ANI" or abbreviations or derivations
thereof in Distributor's corporate titles, or in any way which might result in
confusion as to Airspan and Distributor being separate and distinct entities.
Distributor admits Airspan's exclusive ownership of the name "Airspan Networks
Incorporated", "Airspan Communications Ltd.", "ANI", "ACL", and any
abbreviations or derivations thereof and all of Airspan's Trademarks (whether
registered or not).  Distributor shall not take any action inconsistent with
Airspan's ownership of such Trademarks; therefore, Distributor shall treat all
of Airspan's items distinctively (as to typography) and shall only use exact
reproductions of all Airspan's symbols (including Airspan's logo).   Distributor
shall not adopt or use any Trademark or product name which may be confusingly
similar to any Airspan Trademark.  Distributor may use the Airspan logo as it
appears on Airspan's letterhead.

10.  CONFIDENTIAL INFORMATION AND TRADE SECRETS.

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

                                    Page 12
<PAGE>

     10.1  In this Agreement, the term "Confidential Information" shall mean
the information of Airspan disclosed to Distributor in connection with its
performance under this Agreement, which is in written, recorded, photographic,
machine-readable, or other physical form or oral information reduced to writing
as soon as practicable after disclosure to Distributor, and which is
conspicuously marked "Confidential", "Proprietary", "Private", or in any other
manner indicating its confidential and/or proprietary nature.  Without
limitation, Confidential Information includes:  (1) Airspan's software products,
materials, data reports, programs, documentation, diagrams, and all related
technical information; (2) all information relating to Airspan's business and
products which is critical to Airspan's position in the marketplace, including
future plans of Airspan relating to the fields of endeavor in which Distributor
performs services for Airspan, the nature of certain work projects to which
Distributor is exposed, and the identity of persons working on those projects;
and (3) any improvements, enhancements, or modifications to the above made by or
on behalf of Airspan during the performance under this Agreement which are
provided, made available, or disclosed by or on behalf of Airspan to
Distributor, or used by Airspan or any of Airspan's other Distributors in
connection with their own sales activities.

     10.2  Trade secrets are confidential information that includes ideas,
concepts, techniques, processes, inventions, knowledge, and know-how developed
by Airspan which:  (1) derives independent economic value, actual or potential,
from not being generally known to, and not being readily ascertainable by proper
means by, other persons who can obtain economic value from its disclosure or
use; and (2) is subject to the efforts of Airspan that are reasonable under the
circumstances to maintain its secrecy.  (This "trade secret" language comes from
the Uniform Trade Secrets Act.)

     10.3  Distributor covenants and agrees that it will use the Confidential
Information solely for the performance of services under this Agreement, and
shall not disclose such Confidential Information to any other person (including
Airspan employees in any other division, group, or entity), firm, or
corporation.

     10.4  Distributor shall use the same degree of care in safeguarding the
Confidential Information as it uses for its own confidential information of like
importance, but no less than reasonable care.  Upon discovery of any disclosure
or misuse of Confidential Information, Distributor shall endeavor to prevent any
further disclosure or misuse.

     10.5  All Confidential Information shall remain the property of Airspan,
and such Confidential Information and all copies thereof shall promptly be
returned to Airspan upon request or, at Airspan 's option, destroyed, in which
case Airspan shall be notified in writing when it has been destroyed.

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

                                    Page 13
<PAGE>

     10.6  Nothing contained in this Agreement shall be construed as granting
to or conferring upon Distributor any rights, by license or otherwise, express
or implied, in Airspan's Confidential Information, other than the right to use
the Confidential Information for the purpose of this Agreement.

     10.7  Any copies of the Confidential Information made by Distributor
shall reproduce proprietary marking and legends included therein, but the
provisions of this Agreement supersede any provisions of such legends
inconsistent herewith.

     10.8  The terms and conditions of this Agreement shall not be disclosed
by Distributor to others, except with the prior, written consent of Airspan, or
as may be required by law or as necessary to establish its rights hereunder.

     10.9  If, in connection with its performance, Distributor discloses to
Airspan any ideas, developments, or inventions conceived or actually reduced to
practice by Distributor prior to its performance hereunder, no relationship,
confidential or otherwise, express or implied, is established with Airspan by
the disclosure thereof.  With respect to any such disclosure, no obligation of
any kind is assumed by nor may be implied against Airspan, its subsidiary, or
associated companies unless a formal, separate, written contract regarding the
subject of disclosure is consummated by the parties, and then the obligation
shall be only as expressed in the separate contract.

     10.10  Distributor agrees that any breach of the provisions of this
Section by Distributor or Distributor's personnel, agents, or subcontractors, or
any third party providing products or services to Distributor will cause
immediate and irreparable injury to Airspan and that, in the event of such
breach, Airspan shall be entitled to injunctive relief and any and all other
remedies available at law or in equity.

     10.11  After Distributor has received Airspan's Confidential Information
and know-how, it will be impossible to segregate Airspan's knowledge and know-
how from other knowledge acquired independently by Distributor.  Accordingly,
during the performance of this Agreement and for three (3) months after
termination of services under this Agreement, Distributor will not offer
services to third parties which compete with the services provided by Airspan
under this Agreement, or otherwise use the knowledge acquired from Airspan in
order to compete with Airspan or its customers.  Notwithstanding anything to the
contrary above, Distributor is not precluded from any activities which concern
product sectors or industries other than those that concern products or services
similar to those offered by Airspan in connection with this Agreement.  Nothing
in this paragraph will be construed to prevent Distributor from providing
service to existing customers of Distributor which would result in their
interruption of service to the public.

     10.12 During the performance of this Agreement and for three (3)
months after termination of services under this Agreement, Airspan will not
offer products or services to third parties which compete with the products or
services provided by Distributor under this Agreement, or otherwise use the
knowledge acquired from Distributor in order to compete with Distributor its
customers

     10.13 The obligations of this Section 10 shall survive the expiration or
termination of this Agreement.

utilized therein) solely on Systems or Equipment provided by Airspan; (c)
forthwith return to Airspan all memory media, documentation and/or other
material that has been modified, updated or replaced; (d) except to the extent
permitted by applicable law not modify, disassemble or decompile such Software,

     11.3 In the event of a breach of this license by Distributor, then Airspan
may, in its discretion, terminate the license with immediate effect, whereupon
Distributor shall return to Airspan all Software and copies thereof within ten
(10) days.

12        EXCUSABLE DELAY.

Airspan shall not suffer any liability for non-performance, defective
performance, or late performance under this Agreement due to causes beyond its
control and without its fault or negligence such as, but not limited to, acts of
God, war (including civil war), civil unrest, acts of government, fire, floods,
explosions, the elements, epidemics, quarantine, restrictions, strikes, lock-
outs, plant shutdown, material shortages, or delays in transportation or delays
of its suppliers or subcontractors for like cause.

In the event of excusable delay as defined in the preceding sentence, then
Airspan, upon giving prompt written notice to Distributor, shall be excused from
such performance on a day-to-day basis to the extent of such prevention,
restriction, or interference (and Distributor shall likewise be excused from
performance of its obligations on a day-to-day basis to the extent Distributor's
obligations relate to the performance so prevented, restricted, or interfered
with), provided that Airspan shall use its best endeavors to avoid or remove
such causes of non-performance and both parties shall proceed to perform with
dispatch whenever such causes are removed or cease to exist.

13.  TERM AND TERMINATION.

     13.1  This Agreement shall remain in effect for sixty (60) months from
the Effective Date (the "Initial Term"). After the Initial Term, the term of the
Agreement may be extended by a further period of five (5) years by mutual
written agreement by the parties in the form of an amendment to this Agreement.
If Distributor wishes to extend the term of the Agreement beyond the Initial
Term, it  must notify Airspan in writing at least six (6) months prior to then
end of the Initial Term. However, nothing contained herein shall be interpreted

other party has not cured the failure within the thirty (30) day period

of such material to any person at any time, notwithstanding the termination of
this Agreement.

     13.6 Airspan shall not be liable to Distributor for damages of any kind,
including incidental or consequential damages, on account of the termination of
this agreement in accordance with this section 13.  Airspan shall not be liable

or growing out of such termination or expiration.  Airspan will recognize
payments due to Distributor for orders received up to ninety (90) days after the
termination or expiration of this Agreement.

Airspan will continue beyond the states term of this agreement or its earlier
termination in accordance with this section, that any investment by Distributor
in the promotion of Airspan's Products will be recovered or recouped, or that
Distributor shall obtain any anticipated amount of profits by virtue of this

the "Initial Warranty Period.")

     14.3 Airspan's obligation and Distributor's sole remedy under this warranty
are limited to the replacement or repair, at Airspan's option, of the defective
Equipment or Software within the Initial Warranty Period. Airspan shall have no
obligation to remedy any such defect if it can be shown that: (a) the Equipment
or Software was altered, repaired, or reworked by any party other than Airspan
without Airspan's prior written consent; (b) such defects were the result of
Distributor's or a third party's improper storage, mishandling, abuse, or misuse
of the Equipment or Software; (c) such defects were the result of Distributor's
or a third party's use of the Equipment or Software in conjunction with
equipment electronically or mechanically incompatible or of an inferior quality;
or (d) the defect was the result of damage by fire, explosion, power failure, or
any act of nature.

     14.4  In no event shall Airspan be obliged to provide on-site maintenance.
Subject to the provisions of this warranty clause, defective parts or components
must be returned by Distributor to Airspan's designated facility located within
the contiguous 48 states in the United States, freight prepaid, within the
Initial Warranty Period, and said defective parts will be repaired or replaced

there was no fault found (NFF), in which event, the Distributor shall pay such
transportation costs, along with Airspan's then prevailing standard NFF charge.

     14.5  Airspan will charge Distributor for any maintenance carried out which
is not covered by the warranties contained in Section 14.2 or Section 15 at
Airspan's then prevailing standard rates for such services.

15.  WARRANTY ON REPAIRED AND REPLACEMENT MATERIALS.

Airspan warrants that, following repair or replacement, the repaired or replaced

Period, whichever is longer.

16.  LIMITATION OF LIABILITY.

     16.1  WITHOUT PREJUDICE TO SECTION 16.4, NEITHER Airspan, NOR ANY OF ITS
OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, REPRESENTATIVES, SHAREHOLDERS, OR

INCIDENTAL, CONSEQUENTIAL, INDIRECT OR PUNITIVE DAMAGES OR LOSSES, ARISING FROM
OR IN CONNECTION WITH THIS AGREEMENT, ANY PURCHASE ORDER PLACED PURSUANT TO THIS
AGREEMENT OR ANY OTHER COLLATERAL CONTRACT, OR FROM OR IN CONNECTION WITH THE
EQUIPMENT OR THE SOFTWARE OR THE USE THEREOF OR THE INABILITY TO USE THEM EITHER
SEPARATELY OR IN COMBINATION WITH OTHER EQUIPMENT OR SOFTWARE, OR FROM ANY OTHER
CAUSE, WHETHER CAUSED BY NEGLIGENCE, BREACH OF CONTRACT, STRICT LIABILITY,
BREACH OF WARRANTY, ON GROUNDS OF FAILURE OF ESSENTIAL PURPOSE OR OTHERWISE.

     16.2  Without prejudice to Sections 16.3 and 16.4, the liability of the
Airspan Parties, taken as a whole, for each event or series of connected events
arising out of or in connection with this Agreement, any purchase order placed
pursuant to this Agreement, or any other collateral contract, or from or in
connection with the Equipment or Software or the use thereof, or the inability
to use them either separately or in combination with other equipment or

and expenses suffered or incurred by them or any of them howsoever arising out
of or related to the breach by Distributor of any of the terms of this
Agreement. Airspan shall notify Distributor forthwith of any claim, demand,
action, suit, proceeding, writ, judgment, order or decree falling within the
scope of this Section 16.5 and shall permit Distributor sole conduct of the same
and shall provide reasonable assistance in relation thereto, subject to
appropriate defense by Distributor and the payment by Distributor of Airspan's
reasonable costs and expenses.

     16.6  Distributor shall include, in its agreements with its customers
pursuant to which Distributor supplies Equipment or Software, provisions
pursuant to which such customers agree that the Airspan Parties shall have no
liability for any of the types of damages referred to at Section 16.1 in

the inability to use them either separately or in combination with other
equipment or software, or from any other causes.

17.  INTELLECTUAL PROPERTY RIGHTS INDEMNITY.

     17.1 Airspan agrees to indemnify and hold Distributor harmless with respect
to any suit, claim, or proceeding brought against Distributor by a third party
alleging that Distributor's use of the Equipment or the Software, separately or
in combination, as a whole or in part, constitutes an infringement of any patent
or copyright or misuse of proprietary or trade secret information.  Airspan
agrees to defend Distributor against any such claims and to pay all litigation
costs, reasonable attorney's fees, settlement payments, and any damages awarded
or resulting from any such claim.

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

<PAGE>

     17.2 Distributor shall promptly advise Airspan of any such suit, claim, or
proceeding and shall co-operate with Airspan in the defense or settlement
thereof.  Airspan shall have sole control of the defense of any action involving
such a claim and of all negotiations for its settlement or compromise.

     17.3 In the event that an injunction is obtained against Distributor's use
of the Equipment and/or the Software, in whole or in part, as a result of any
such claim, Airspan shall use its best efforts to either: (a) procure for
Distributor the right to continue using the portions of the Equipment or the
Software enjoined from use; or (b) replace or modify the same with functionally
equivalent or better Equipment and/or Software so that Distributor's use is not
subject to any such injunction.  In the event that Airspan cannot perform the
remedies set forth in Sections 17.3(a) or 17.3(b), then Distributor shall have
the right to return such Equipment and the Software to Airspan.  In the event of
such return, Airspan shall refund the depreciated value of the Equipment and the
license to use the Software within thirty (30) days of the receipt by Airspan of
the Equipment and the Software.

     17.4 This indemnity shall not apply to claims arising in respect to the use
of the Equipment or Software supplied by Airspan or manufactured by its
suppliers in accordance with any design or any special instruction furnished by
Distributor, or which is used by Distributor in a manner or for a purpose not
contemplated by this Agreement.

     17.5 The provisions of this Section 17 set forth the entire obligation of
Airspan with respect to any claim of patent infringement, copyright
infringement, or misuse of proprietary or trade secret information.

18.  EXPORT CONTROLS AND LEGAL COMPLIANCE.

     18.1 If any approval with respect to this Agreement, or the registration
thereof, shall be required at any time during the term of this Agreement, with
respect to giving legal effect to this Agreement in the Territory, or with
respect to compliance with exchange regulations or other requirements so as to
assure the right of remittance abroad of United States dollars pursuant to
Section 6 hereof, Distributor shall immediately take whatever steps may be
necessary in this respect, and any charges incurred in connection therewith
shall be for the account of Distributor.  Distributor shall keep Airspan
currently informed of its efforts in this connection.  Airspan shall be under no
obligation to ship Airspan Products to Distributor hereunder until Distributor
has provided Airspan with satisfactory evidence that such approval or
registration is not required or that it has been obtained.

     19.2 Airspan agrees to provide Distributor at no additional charge with its
standard package of documentation related to the use, maintenance, and
installation of Airspan Products.  In the event that such documentation is
modified during the term of this Agreement, Airspan agrees to provide to

create possible conflicts of interest will be revealed to Airspan as soon as
they become known by informing Airspan of any business relationships,
circumstances, or situations which could prejudice in any way

21.  MISCELLANEOUS.

     21.1  Pursuant to the Foreign Corrupt Practices Act of the United States
of America, directors, officers, or employees of Distributor shall not offer or
pay any bribe to any individual or corporation in connection with the provision
or support of any Airspan Products obtained under this Agreement. When other
individuals or organizations are required to participate in the sales program
covered by this Agreement, they shall be compensated fairly based on the tasks

to be offered or paid any bribe or other benefit, direct or indirect.  No
contribution in any way related to Airspan shall be made to candidates for
public office or to political parties or other political organizations,
regardless of whether such contributions are permitted by the laws of the
Territory.  The parties agree that both parties will comply fully with all of
the terms, conditions, rules, regulations and statutes of the Foreign Corrupt
Practices Act.  The parties further agree that if either party violates any of
the provisions of said Act, the party violating the Act will indemnify the other
party from any and all liability thereunder, including costs, expenses, fines or
legal fees.

     21.2  In performing this Agreement,  the parties shall comply with all
applicable laws, rules, and regulations, and shall indemnify, defend and save
each other harmless from  said party's failure to do so.  Furthermore, if this

parties' exercise of any of their rights hereunder or of any options hereunder
under the terms or covenants herein shall not preclude or prejudice the parties

1.   SCOPE.
     -----

     1.1  This Agreement shall remain in effect for a period of sixty (60)
     months from the Effective Date (the "Term").

     1.2  During the Term, in accordance with each Purchase Order issued by
     Purchaser and accepted by Airspan, Airspan shall:

          a. Engineer, sell and deliver that equipment and services so
     specified in the order ("Equipment" being defined as the hardware component
     of each product being offered under the terms and conditions of this
     Agreement);

          b. Grant to Purchaser a non-transferrable, non-exclusive, paid-up
     licence to use the Software (as defined in Section 10.1) during the useful
     life of the associated Equipment on the terms and conditions set forth in
     the Software Licence, Section 10. The license to use the Software (as
     defined in Section 10.1) may be transferred by written authorisation from
     Airspan to Purchaser, provided that Airspan will not unreasonably withhold
     said written authorization;

          c. Test and install the Equipment and/or Software (the "Installation
     Services") if Purchaser elects to purchase the Installation Services, and
     Airspan accepts the obligation to perform such services, or if such
     services are included in the price of the Equipment or Software.

2.   ORDERING PROCEDURE.
     ------------------

     2.1  The following procedures shall be followed with respect to each
     purchase order issued by Purchaser:

     a.  During the Term, Purchaser will inform Airspan of its intent to
     purchase Equipment and Installation Services (but only if Airspan expressly
     agrees to perform such Installation Services), and license Software, by
     sending to Airspan a written order.  This written order (the "Purchase
     Order") will state the type of Equipment, System, or Installation Services
     that Purchaser wants to purchase and the Software Purchaser wants to
     licence, the price of the ordered items (the "Contract Price") as set forth
     in Exhibit B, "Price List" (which is hereby incorporated by reference) and
     the proposed delivery and installation dates, if applicable.

     b.  Each Purchase Order shall specifically incorporate by reference the
     terms and conditions of this Agreement, and no additional or different
     terms and conditions stated in a Purchase Order, any letter, or otherwise
     shall be binding unless expressly referred and agreed to by Airspan in
     writing. In the event of a

-------------------------------------------------------------------------------
<PAGE>

     conflict between the terms and conditions of this Agreement and of any
     Purchase Order issued hereunder, or if the Purchase Order does not
     reference the terms and conditions of this Agreement, the terms and
     conditions of this Agreement shall control.

     2.2  If a Purchase Order is accepted by Airspan, Airspan will issue an
     order acknowledgement to Purchaser within five (5) business days of
     Airspan's receipt of the written Purchase Order from Purchaser.

3.   CONTRACT PRICE.
     --------------

     3.1  The Contract Price for each item of Equipment, Installation Services,
     or Software is as specified in Exhibit B and shall be paid to Airspan in US
     Dollars free of any withholding tax and any currency controls or other
     restrictions.  The Contract Price includes:

          a. The price of the Equipment;

          b. The fee for the licensing of the Software;

          c. If Installation Services are ordered and such order is accepted by
          Airspan, the charges for installing and testing each unit of Equipment
          or Software;

          d. The charges for the warranty of the Equipment and Software in
          accordance with Section 7; and

          e. Costs in accordance with delivery obligations set forth in Sections
          5.1 and 5.2.

     3.2  The Contract Price is shown in Exhibit B and shall include applicable
     duties, taxes or imposts, including all export or import duties. Sales
     taxes and contractor's excise taxes shall be itemized on all purchase
     orders.  The parties agree that the Contract Price in Exhibit B shall be
     firm for a minimum period of twenty-four (24) months from the Effective
     Date. Thereafter, Exhibit B may be revised by Airspan giving thirty (30)
     days written notice to Purchaser.

4.   PAYMENT TERMS.
     -------------

          4.1  Airspan will issue an invoice (the "Invoice") to Purchaser in
     accordance with the payment terms below. The Invoice specifically will
     identify the Equipment, Software, or other items shipped, and the Contract
     Price of such

-------------------------------------------------------------------------------
<PAGE>

     items. Any Installation Services or other services provided by Airspan will
     be invoiced separately following completion of such services. The Invoice
     also shall state the total due to Airspan from Purchaser (the "Invoice
     Total"), which shall include the Contract Price, and any applicable taxes,
     duties, and other fees due pursuant to Section 3.2 of this Agreement.
     Payment of the Invoice Total is due (without any right of set-off) Net
     forty-five (45) days after the date of invoice.

     4.2  If Purchaser disputes any invoice or part thereof, Purchaser must
     notify Airspan in writing within twenty-five (25) days of the invoice date
     giving details of the reason for such dispute. Purchaser and Airspan agree
     to work together in good faith to resolve the dispute as quickly as
     possible. Purchaser may withhold payment of such disputed amounts until
     resolution of the dispute. Any parts of the invoice not under dispute shall
     be paid net forty-five (45) days after the date of invoice. On resolution
     of the dispute, Purchaser shall immediately pay any amounts due in full.

     4.3  Purchaser will make payment by wire or telegraphic transfer to the
     bank account set forth below or, on receipt of written notification from
     Airspan, to another designated bank within the United States.

     Bank:            Seafirst Bank, 10555 N.E. 8th, Bellevue, WA98004, USA.
     Account name:    Airspan Networks Inc.
     Account number:  68777507
     Routing Number:  125 - 0000 - 24
     Further instructions: "Reference (Purchaser's name), Purchase Order number,
     Payment of Invoice number"

     Payment will be deemed to have been made upon receipt of funds in Airspan's
     bank.

     4.4  If the cost to Airspan of performing this Agreement increases as a
     result of any change to the law or increase in import duty or freight duty,
     Airspan may add such increase to the Contract Price by notifying Purchaser
     in writing of such increase.

5.   DELIVERY, TITLE AND RISK OF LOSS.
     --------------------------------

     5.1  All Equipment and Software will be delivered by Airspan CIP (as
     defined in Incoterms 2000) to an airport in South Dakota that completes
     international customs clearances and shipped to a location within the city
     limits of the above arrival airport, such airport and delivery location are
     to be agreed upon in writing by the parties for each Purchase Order.
     Airspan will be responsible for and pay all packing, shipping, freight, and
     insurance charges to the agreed upon location within the city limits. If
     requested by Purchaser,

-------------------------------------------------------------------------------
<PAGE>

     Airspan may arrange for shipment to be made to Purchaser's identified
     warehouse facilities or freight forwarder outside of the city limits,
     subject to approval in writing by Airspan and agreement to any additional
     charges in advance of shipment. Unless specified in the Purchase Order,
     Airspan will select the mode of shipment and the carrier.

     In this Agreement, "Incoterms" means the most recent international rules
     for the interpretation of trade terms published by the International
     Chamber of Commerce as in force on the Effective Date.  Unless the context
     otherwise requires, any term or expression which is defined in or given a
     particular meaning by the provisions of the Incoterms shall have the same
     meaning in this Agreement, but if there is any conflict between the
     provisions of the Incoterms and this Agreement, the latter shall prevail.

     5.2 All risk of loss or damage to the Equipment and Software will pass to
     Purchaser on collection by the freight forwarder from Airspan. However,
     Airspan will insure the Equipment against loss or damage in transit to the
     agreed upon location within the city limits as set forth in Paragraph 5.1.

     5.3  Title to the Equipment shall pass to Purchaser on collection by the
     freight forwarder from Airspan.

     5.4  If Purchaser has any Airspan owned Equipment in its possession:

          a.  Purchaser shall ensure that Equipment is clearly marked as the
          property of Airspan, and if asked, shall inform any third parties that
          the Equipment is the property of Airspan;

          b.  Purchaser shall not purport to create any security, mortgage,
          lien or pledge over the Equipment, or otherwise deal with the
          Equipment without Airspan's written consent;

          c.  In the event of any threatened seizure of the Equipment by any
          third parties, and on termination or expiration of this Agreement, or
          any Contract made pursuant to it, Airspan shall have the right,
          without prejudice to any other remedy, to enter without prior notice
          any premises and to repossess and take away or otherwise deal with the
          Equipment.

     5.5  The Software shall at all times remain the exclusive property of
     Airspan, subject to the uses provided herein.

     5.6  Unless Purchaser clearly advises Airspan to the contrary in writing,
     Airspan may make partial deliveries on account of Purchase Orders. Delay in
     delivery of any instalment shall not relieve Purchaser of its obligation to
     accept

-------------------------------------------------------------------------------
<PAGE>

     said installment, provided that said delay does not exceed sixty (60) days
     from Airspan's scheduled ship date and unless Purchaser has clearly advised
     Airspan to cancel the delayed installment in writing at least fifteen (15)
     days prior to its revised planned shipment date or its actual shipment date
     by Airspan.

     5.7  Airspan will use reasonable efforts to meet Purchaser's requested
     delivery schedules for Equipment and Software, but Airspan reserves the
     right to refuse, or delay delivery to Purchaser when Purchaser's credit is
     impaired, when Purchaser is delinquent in payments or fails to meet other
     credit or financial requirements reasonably established by Airspan, or when
     Purchaser has failed to perform its obligations under this Agreement.

     5.8  Should orders for Equipment and Software exceed Airspan's available
     inventory, Airspan will allocate its available inventory and make
     deliveries on a basis that Airspan deems equitable, in its sole discretion,
     and without liability to Purchaser on account of the method of allocation
     chosen or its implementation. In any event, Airspan shall not be liable for
     any direct, indirect, consequential, or special losses or damages
     (including, but not limited to, loss of income or profit and loss of data)
     that may be suffered by the Purchaser or by any other person for failure to
     deliver or for any delay or error in delivery of Equipment or Software for
     any reason whatsoever.

6.   SUBCONTRACTING.  Airspan reserves the right to subcontract such portions
     --------------
of:  (a) the Equipment manufacture and/or Software development and supply;
and/or (b) installation to subcontractors of Airspan's choice as Airspan deems
appropriate.

are limited to the replacement or repair, at Airspan's option, of the defective

obligation to remedy any such defect if it can be shown that:  (a) the Equipment

without Airspan's written consent; (b) such defects were the result of
Purchaser's improper storage, mishandling, abuse, or misuse of the Equipment or

to Purchaser.  Purchaser will pay all transportation costs for Equipment or
Software shipped to Airspan for repair or replacement.  Airspan shall pay all
transportation costs associated with returning repaired or replaced Equipment or
Software to Purchaser.

     7.5  Airspan will charge Purchaser for any maintenance carried out which is
not covered by the warranties contained in Section 7.2 or Section 8 at Airspan's
then prevailing standard rates for such services.

8.   WARRANTY ON REPAIRED MATERIALS.  Airspan warrants  that, following repair,
     ------------------------------

to do so, without Airspan's prior written consent; and (5) not reproduce or copy
such Software in whole or in part except for backup and archival purposes or as
otherwise permitted in writing by Airspan. Information to achieve
interoperability of the Software with independently created programs, within the
meaning of Article 6 of the Directive on the Legal Protection of Computer
Programs, is available from Airspan on written request.

     10.3 The obligations of Purchaser under this Section 10 shall survive the
termination of this Agreement for any reason and shall continue even if the
Software is no longer utilised with the Equipment.

11.  DOCUMENTATION.  Airspan shall furnish that documentation, if any, specified
     -------------
in Exhibit B to Purchaser to be used for the operation and ongoing maintenance
of the Equipment and Software.  All such documentation is to be treated in
accordance with the terms of Section 12.  Updates to the documentation shall be
at no charge during the Initial Warranty Period.

12.  CONFIDENTIAL INFORMATION.
     ------------------------

     12.1   All technical information, documentation, Software and other
proprietary information ("Confidential Information") supplied by Airspan to
Purchaser under this Agreement, except for that which may be in the public
domain, shall, as between the parties hereto, be treated as the confidential and
proprietary information of Airspan.  Purchaser, except as specifically
authorised in writing by Airspan, shall:  (a) not disclose any Confidential
Information received from Airspan to any person, except to its employees on a
"need-to-know" basis; (b) not reproduce any Confidential Information received
from Airspan, in whole or in part; (c) use any Confidential Information received
from Airspan only for operation and maintenance of the Equipment; and (d)
indemnify Airspan for any loss or damages resulting from a breach of this
Section 12.

     12.2  If this Agreement is terminated or cancelled, or if Purchaser is
found to have breached any of the provisions of Sections 10 or 12, Purchaser
agrees to immediately return all technical information, documentation, and
Software to Airspan, with the exception of the AS8100 (Sitespan) network
operating software. In any event, the obligations of Sections 10 and 12 will
survive termination or cancellation of this Agreement.

13.  EXCUSABLE DELAY.
---  ---------------

     13.1 Airspan shall not suffer any liability for non-performance, defective
performance, or late performance under this Agreement due to causes beyond its

-------------------------------------------------------------------------------
<PAGE>

control and without its fault or negligence such as, but not limited to, acts of
God, war (including civil war), civil unrest, acts of government, fire, floods,
explosions, the elements, epidemics, quarantine, restrictions, strikes, lock-
outs, plant shutdown, material shortages, or delays in transportation or delays
of its suppliers or subcontractors for like cause.

In the event of excusable delay as defined in the preceding sentence, then
Airspan, upon giving prompt written notice to Purchaser, shall be excused from
such performance on a day-to-day basis to the extent of such prevention,
restriction, or interference (and Purchaser shall likewise be excused from
performance of its obligations on a day-to-day basis to the extent Purchaser's
obligations relate to the performance so prevented, restricted, or interfered
with), provided that Airspan shall use its best endeavours to avoid or remove
such causes of non-performance and both parties shall proceed to perform with
dispatch whenever such causes are removed or cease to exist.

     13.2 The parties reserve the right to cancel or otherwise terminate this
Agreement if the parties' performance is delayed for a period of more than sixty
(60) days as a result of excusable delay as defined in Section 13.1.

14.  GENERAL INDEMNITY.
     -----------------

     14.1  Airspan agrees to indemnify and hold Purchaser harmless against all
costs, expenses, liabilities, damages, losses, claims, or proceedings incurred
by Purchaser in an action by a third party alleging that Purchaser's use of the
Equipment or the Software, separately or in combination, as a whole or in part,
constitutes an infringement of their intellectual property rights wherever in
the world enforceable, including applications to register and rights to apply
for any such rights ("Intellectual Property Rights").  Airspan agrees to defend
Purchaser against any such claims and to pay all litigation costs, reasonable
lawyer's fees, settlement payments, and any damages awarded or resulting from
any such claim.

     14.2 Purchaser shall promptly advise Airspan of any such suit, claim, or
proceeding and shall co-operate with Airspan in the defence or settlement
thereof.  Airspan shall have sole control of the defence of any action involving
such a claim and of all negotiations for its settlement.

     14.3 In the event that an injunction is obtained against Purchaser's use of
the Equipment and/or the Software, in whole or in part, as a result of any such
claim, Airspan shall use its best efforts to either: (a) procure for Purchaser
the right to continue using the portions of the Equipment or the Software
enjoined from use; or (b) replace or modify the same with functionally
equivalent or better Equipment and/or Software so that Purchaser's use is not
subject to any such injunction.  In the event that Airspan cannot perform the
remedies set forth in Sections 14.3(a) or 14.3(b), then Purchaser shall

-------------------------------------------------------------------------------
<PAGE>

have the right to return such Equipment and the Software to Airspan. In the
event of such return, Airspan shall refund the depreciated value of the
Equipment and the licence to use the Software within thirty (30) days of the
receipt by Airspan of the Equipment and the Software.

     14.4  This indemnity shall not apply to claims arising in respect of the
use of the Equipment or Software supplied by Airspan or manufactured by its
suppliers in accordance with any design or any special instruction furnished by
Purchaser, or which is used by Purchaser in a manner or for a purpose not
contemplated by this Agreement.

     14.5  The provisions of this Section 14 set forth the entire obligation of
Airspan with respect to any claim of infringement of Intellectual Property
Rights.

15.  REMEDIES AND TERMINATION.
     ------------------------

     15.1  Airspan shall have the right, prior to payment to Airspan of the
Invoice Total, to suspend its performance under this Agreement by written notice
to Purchaser and forthwith remove and take possession of any Equipment and
operating Software which has been delivered if Purchaser shall:  (a) become
insolvent; (b) have a receiver or manager appointed over the whole or any part
of its assets or business; (c) make any composition or arrangement with its
creditors; (d) take or suffer any similar action in consequence of debt, or an
order or resolution is made for its dissolution or liquidation (other than for
the purpose of amalgamation or reconstruction); or (e) if Purchaser attempts to
resell the Equipment or Software without the consent of Airspan.

     15.2  In the event of any material breach of this Agreement by either party
which shall continue for thirty (30) or more days after written notice of such
breach (including a reasonably detailed statement of the nature of such breach)
shall have been given to the breaching party by the aggrieved party, the
aggrieved party shall be entitled at its option:  (a) if the aggrieved party is
Purchaser, to suspend its performance under Section 4 of the Agreement for as
long as the breach continues uncorrected; or (b) if the aggrieved party is
Airspan, to suspend performance of all of its obligations under the Agreement
for as long as the breach continues uncorrected; (c) to avail itself of any and
all remedies available at law or equity whether or not it elects to suspend its
performance under Section 15.2(a) or 15.2(b) as applicable; or (d) to terminate
this Agreement.

     15.3  In the event (a) either party fails timely to discharge its
obligations under this Agreement and (b) the aggrieved party employs a lawyer in
order to collect any amount due and unpaid or to enforce any right or remedy
hereunder, then the defaulting party agrees that, in addition to all amounts due
hereunder, it shall pay all costs of collection or enforcement including court
costs and reasonable Lawyer's fees.

18.  HARDWARE AND SOFTWARE VERIFICATION
     ----------------------------------

     18.1 If Installation Services are ordered, Airspan shall, upon completion
of the installation, test the Equipment.  Purchaser may witness the installation
and test performance.

-------------------------------------------------------------------------------
<PAGE>

     18.2 When the Equipment and Software have satisfactorily completed all of
Airspan's tests, Airspan shall provide Purchaser with a "Hardware and Software
Verification" certificate.  Provision of the certificate to Purchaser will be
deemed, for purposes of this Agreement, as "Completion of Installation".

19.  PUBLICITY.  Purchaser agrees not to publish any press releases or otherwise
     ---------
publicise the existence, or any of the terms, of this Agreement without the
prior written consent of Airspan.

20.  MISCELLANEOUS
     -------------

     20.1 This Agreement shall be construed in accordance with and governed by
the laws of  the State of South Dakota.

     20.2  Any dispute, controversy or claim between the parties arising out
of, or in connection with, this Agreement, or the breach, termination or
validity thereof will be resolved by mutual agreement of the parties, provided
that this shall not limit the ability of the parties to seek temporary or
interim injunctive relief in the event of any breach or threatened or impending
breach of the confidentiality provisions of this Agreement.  If any dispute,
controversy, or claim arising out of or relating to this Agreement, or the
breach, termination or validity thereof is unable to be resolved by mutual
agreement of the parties, each of the parties here (i) agrees that any action,
suit or proceeding with respect to this Agreement against it or its properties
or revenues must be brought exclusively in the federal and state courts siting
in Chicago, and (ii) irrevocably submits to the exclusive jurisdiction of any
such court and any appellate court from any order or judgment thereof in any
such action, suit or proceeding.  The parties hereby irrevocably agree that all
claims in respect of such action, suit or proceeding may be heard and determined
in such courts. The parties hereby irrevocably waive, to the fullest extent they
may effectively do so, the defence of an inconvenient forum to the maintenance
of such action, suit or proceeding.  The parties agree that a final judgment in
any such action, suit, or proceeding will be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law.

     20.3 Airspan's delay or failure to enforce at any time any of the
provisions of this Agreement or any right with respect thereto, or to exercise
any option herein provided shall in no way be construed to be a waiver of such
provision, rights, or options, or in any way to affect its right later to
enforce them.  Airspan's exercise of any of its rights hereunder or of any
options hereunder under the terms or covenants herein shall not preclude or
prejudice Airspan from thereafter exercising the same or any right which it may
have under this Agreement, irrespective of any previous action or proceeding
taken by Airspan hereunder.

-------------------------------------------------------------------------------
<PAGE>

     20.4 This Agreement shall be binding upon and inure to the benefit of the
successors and permitted assigns of Airspan and shall be binding upon and inure
to the benefit of Purchaser's heirs, legal representatives, successors and
permitted assigns.

     20.5 This Agreement and any Exhibit hereto shall be modified only by an
instrument in writing that is signed by duly-authorized representatives of the
parties.

     20.6 This Agreement is executed in English only, and Purchaser hereby
waives any right that it may have under the laws of any other jurisdiction to
have this Agreement executed in any other language.

     20.7 The provisions of this Agreement are severable, and if any provision
is held invalid or unenforceable in whole or in part in any jurisdiction, then
such invalidity or unenforceability will affect only such provision or part
thereof in such jurisdiction, and will not in any manner affect the provision in
any other jurisdiction, or any other provision in this Agreement in any other
jurisdiction.  To the extent legally permissible, an arrangement that reflects
the original intent of the parties will be substituted for such invalid or
unenforceable provision.

     20.8 All obligations that by their nature survive the expiration,
cancellation or termination of this Agreement shall remain in effect after its
expiration, cancellation or termination.

     20.9 Purchaser shall not be entitled to assign this Agreement or its rights
under it without the prior written consent of Airspan, which said consent shall
not be unreasonably withheld.  Airspan may assign the Agreement or its rights
under it without recourse to Purchaser.

     20.10  In the performance of its obligations under this Agreement,
Purchaser shall at all times strictly comply with all export laws, regulations,
and orders of the United Kingdom and the United States of America. Purchaser
specifically acknowledges that Equipment, Software or technology supplied or
licensed by Airspan under this Agreement are subject to U.K. and U.S. trade
sanctions and export control laws and regulations including, but not limited to,
the various Foreign Assets Control Regulations, the Export Administration
Regulations, and the International Traffic in Arms Regulations. Purchaser
specifically acknowledges that Equipment, Software, or technology obtained from
Airspan pursuant to this Agreement shall not be exported, reexported,
transhipped, disclosed, diverted, or transferred, directly or indirectly,
contrary to U.K. and U.S. laws, orders or regulations.

respect to the subject matter hereof, and supersedes all previous

written, between the parties or any official or representative thereof.
