                          LOW CAPACITY DIGITAL RADIO
                               PRODUCT AGREEMENT

This Agreement is made by and between:

P-COM INC. a corporation under the law of Delaware and having its registered
office at 200 E. Hacienda Ave. Campbell, CA 95008, hereinafter referred to as
"P-COM"

and

SIEMENS TELECOMUNICAZIONI S.P.A. a corporation under the law of Italy and having
its registered office at 20060 Cassina de' Pecchi, Italy, S.S. Padana Superiore
km. 158, hereinafter referred to as "Siemens"

(P-COM and Siemens are hereinafter referred to jointly as the "Parties" and
individually as a "Party")

whereas P-COM has developed the Tel-Link radio Product Line presently covering
the 23, 38 and 50 GHz frequency bands and allowing the transport of one or more
1.5 (T1) or 2 (E1) Mbit/s traffic signals;

whereas Siemens is willing to introduce the products of the Tel-Link Product
Line into its own catalogue and to place orders to buy certain amounts of these
products;

being the recitals hereinabove integral part of the present Agreement


                   NOW THEREFORE THE PARTIES AGREE AS FOLLOWS


ARTICLE 1. PURPOSE OF THE AGREEMENT

1.1 The purpose of this Agreement is to set forth rules that allow Siemens to
include the Tel-Link Product Line (hereinafter "the Products", which terms shall
also be construed as designating equipment, subset, assembly or part of the Tel-
Link Product Line where The context so admits) in its products catalogue.

1.2 As a consequence P-COM agrees to Sell and Siemens agrees to buy the Products
in accordance with purchase orders that may be issued from time to time by
Siemens to The price, terms and conditions herein contained.

ARTICLE 2. SPECIFICATIONS OF THE PRODUCTS AND RELEVANT SIEMENS ACCEPTANCE TEST

2.1 P-COM grants that the characteristics and specifications of the Products at
the date of the Agreement are those listed in the Attachment I hereto.

                                  Page 1 of 9
<PAGE>

2.2  In the spirit of the present Agreement, should P-COM decide to modify the
Products with enhancements or extensions, P-COM is willing to make available to
Siemens the above mentioned enhancements and extensions and to timely provide
Siemens with sufficient information and documentation in order to promote the
enhanced and extended Products in the market.

2.3  if the enhanced Products should not grant full backword compatibility, P-
COM undertakes to produce the previous version of the Products for Siemens for a
minimum period of 24 months after the commercial availability of the enhanced
Products.

2.4 The characteristics and conditions related with the Quality Assurance are
detailed in the Attachment 2 hereto.


ARTICLE 3. MARKETING RIGHTS

3.1 Siemens will have the non exclusive right to promote, sell or lease, as a
single equipment or together with other products or systems, the Products in any
market freely and with no limitations.

3.2 Siemens will have the right to include the Products in its catalogue with
Siemens trade-mark and brand name. To this purpose P-COM agrees to deliver to
Siemens the Products properly marked and externally coloured in accordance with
Siemens' instructions, provided that such instructions will not be in conflict
with the production process of the Products.

3.3 P-COM warrants that it does not have nor will undertake any obligation with
anybody conflicting with the rights granted to Siemens pursuant to this
Agreement


ARTICLE 4. PRICES

4.1 The prices from P-COM to Siemens of the Product are given in the Attachment
3 to this Agreement. Prices are fixed throughout each calendar year and will be
revised annually in a joint meeting to be held by the Parties by 30th of
September of the previous year. Basic criterion adopted in defining price is to
allow Siemens to withhold a reasonable margin, estimated by the Parties in
approximately *** on the most competitive market price recognized by the Parties
provided P-COM can also obtain a reasonable margin.

4.2 Price vs. quantity matrix is given in the Attachment 3, based on the total
number of transmitters/receivers of the Products ordered by Siemens for delivery
within the year.
The initial price level of each year will be defined during the annual meeting
according to the quantity objective indicated by Siemens.

In case after six months of each year the total ordered transmitter/receiver do
not reach *** **** ****** of the minimum quantity of the initial price level,
The purchase order price for the second six months will automatically switch to
the lower quantity level.

Viceversa, whenever during a year Siemens inform P-COM that the total expected
ordered quantity for the same year would exceed the minimum of the initial price
level agreed for that year, the purchase order price will switch to the higher
quantity level three months after the notification by Siemens of the higher
volume.

For year 1995 the initial price level will be level * while the quantities in
Attachment 3 have to be considered reduced by *** **** ******.

                                  Page 2 of 9

                                              *CONFIDENTIAL TREATMENT REQUESTED.
<PAGE>

4.3 In the event that during the one year time frame of validity of certain
price levels, the competitive market price - which is used as reference in
defining price - reduces considerably, the Parties agree to meet and jointly
review the price in accordance with such modified market conditions and
following the basic criterion indicated at point 4.1.


ARTICLE 5. CONDITIONS OF SUPPLY

5.1 Unless otherwise agreed in relation with a specific project the following
terms and conditions shall be applicable to all orders for the purchase of the
Products (or portion thereof) to be supplied by P-COM to Siemens and such terms
and conditions shall take preference over any conflicting or inconsistent terms
of Siemens' purchase orders or P-COM conditions of sale.

5.2 Siemens, shall purchase the Products by issuing a written purchase order, to
be transmitted by fax, identifying the transmitters/receivers of the Products to
be purchased, the quantity, price, total purchase order price, shipping
instructions (if any), delivery dates and place and any other specific
information impacting on the equipment delivery schedule. P-COM shall confirm,
by confirmed telefax, any purchase order within one (1) week of P-COM's receipt
thereof, provided its terms are in accordance with those of this Agreement or
better ones, if so agreed by the Parties.

5.3 Price, ** **** ******* are defined in the Attachment 3 to this Agreement.
Price shall include the full cost of ordered products, suitably packed.

5.4 Depending of the specific indications of the purchase order, the ordered
Products will be delivered, at the price indicated in Attachment 3, in one of
the following ways:

-  for European Communities and E.F.T.A. Countries and other European Countries
   with equivalent import custom duties, *** ******* ** ************ ******
   ****** ****** **** (in accordance with Incoterms 1990);

-  for other European Countries with import custom duties higher than E.E.C.
   (7.5%) *** ******* ** ************ ****** ****** ****** **** in accordance
   with Incoterms 1990), *** ***** **** ***** *** *** ****** ***********
   ********** ** ********

-  for all the other Countries, *** ******** ****** (in accordance with
   Incoterms 1990). Delivery dates will be those specified in the order and in
   any case the lead time will not be less than the standard lead time declared
   by P-COM with the exception of different lead time accepted by P-COM in
   writing for specific orders.

P-COM declares that standard lead time from the reception of purchase order to
delivery *** is * ***** provided that the order is within the boundaries of the
monthly rolling forecast covering the subsequent * months as defined herebelow;
any variations in standard lead time will be promptly notified by written notice
to Siemens.

5.5 Siemens will issue monthly a rolling forecast (with the best possible
indications of frequency, bit rate and configurations) indicating requested
deliveries for the coming six months - divided in months - of which the first
month is covered by firm orders and the subsequent two months are binding in
terms of quantities and configurations.

It is understood that the binding forecast of the subsequent two months allow
Siemens to reduce actual orders of *** in the second month and of *** in the
third month.

First forecast is in Attachment 4; next forecast will be issued by Siemens on
the last working day of the month that follows the date of signature of the
Agreement.

                                              *CONFIDENTIAL TREATMENT REQUESTED.

                                  Page 3 of 9
<PAGE>

5.6 Unless otherwise agreed by the Parties in relation with a specific project,
Siemens' payment to P-COM shall be made for 100% of the relevant price of each
delivered batch, ****** **** days end of the month date of invoice after
shipment of each complete batch of supply and issuance of relevant invoice.

5.7 In the event that P-COM fails for reasons other than causes of force majeure
to deliver FCA each batch of the Products or parts thereof at the respective
dates accepted in the relevant purchase order, Siemens may claim from P-COM
penalties equivalent to ** *** **** ***** of the corresponding price of the
delayed batch per week of delay without exceeding *** **** ******** of said
price. P-COM shall inform immediately Siemens in the event it anticipates any
delay in its deliveries and the Parties shall make their best efforts to
minimise the consequences thereof.

If due to joint efforts of the Parties, the delay in P-COM deliveries does not
delay Siemens' performance of its obligation towards its customer and therefore
no penalties are charged to Siemens, P-COM may elect to reimburse in full to
Siemens all extra or special costs incurred by Siemens during above mentioned
joint efforts instead of being charged penalties hereunder.

In the event Siemens cancels or delays by more than three months any shipment
firmed up in the first three months of the rolling forecast, P-COM will make its
best efforts to redirect the shipment elsewhere to the extent possible. Failing
that P-COM shall inform Siemens in writing within 1 week and Siemens will be
under the obligation to buy and pay for the equipment as follows:

 . **** of the equipment scheduled to ship in the month following cancellation;
 . *** of the equipment scheduled to ship in the period contained between 1
  month and 2 months from the date of cancellation;
 . *** of the equipment scheduled to ship in the period contained between 2
  months and 3 months from the date of cancellation.

Upon Siemens request P-COM cooperate in safely storing the equipment and will
advise Siemens of the cost to be born.

5.8 Notwithstanding the article 11 (Duration), P-COM undertakes to supply, for *
year after the expiration of the present Agreement, equipment to Siemens for all
the expansions of the contracts signed by Siemens during the validity of the
present Agreement.

5.9 If specific market opportunities pursued by Siemens in relation with the
Products require a local content (either explicitly or as a competitive
advantage), P-COM and Siemens will jointly analyse and decide the best strategy
to be followed with respect to the granting of the manufacturing rights to the
third party addressed in the specific project. Terms and conditions for the
above manufacturing transfer will be negotiated in good faith by the Parties.


ARTICLE 6. INSPECTION ON THE PRODUCTS MANUFACTURING PROCESS.

6.1 In order to certify the quality of the Products and of its manufacturing
process and to allow Siemens to fulfill its contractual obligations with the
customer, Siemens may at any reasonable time inspect, in P-COM' and/or P-COM'
subcontractors' facilities, the various manufacturing steps of the products
which will or may be used in the performance of this Agreement and inspect and
test material and workmanship related to the Products

                                              *CONFIDENTIAL TREATMENT REQUESTED.

                                  Page 4 of 9
<PAGE>

purchased hereunder Siemens shall give P-COM reasonable prior notice of the
dates on which the inspections will take place. All inspections and tests shall
be performed in such a manner as not to delay the work unduly.

The Parties will jointly define specific procedures to carry out the
inspections.


ARTICLE 7. WARRANTY AND SPARE PARTS

7.1  The Products to be supplied by P-COM hereunder shall be warranted to
conform to the specification which are or will become applicable as a result of
this Agreement and its Attachment 1 and to be free from design errors and

Section 8:   Loopbacks:                      Three types of loopbacks are
                                             offered:

     IDU Loopback:                           Loops the aggregate date before the
                                             "N" connector of the IDU. Tests all
                                             circuits in the IDU for operation.
                                             An external BERT set is needed to
                                             test for error performance. Traffic
                                             affecting on all tributaries.

     ODU Loopback:                           Used only with the Loopback Test
                                             Transistor (LBT) to allow testing
                                             of an entire terminal. The LBT
                                             consists of a number and a 1008 or
                                             1232 MHz oscillator.

     Link Loopback:                          Loops the far end tributary at the
                                             line driver and returns the E1
                                             signal to the local end. Affects
                                             only the tributary selected. An
                                             external BERT set is needed to
                                             perform error rate tests.

   On-Line LED                            Green indicates power is applied to
                                          unit.
   IDU LED                                Green indicates normal. Flashes or
                                          solid red in alarm.
   ODU LED                                Green indicates normal. Flashes or
                                          solid red in alarm.
   CBL (Cable) LED                        Green indicates normal. Red when cable
                                          short or open.
   RMT (Remote) LED                       Green indicates normal. Flashes or
                                          solid yellow when far end terminal is
                                          not in normal operation.

External Alarms:                          Up to eight external alarms can be
                                          used per IDU for site alarms such as
                                          Open door, Temperature, A/C Fail, etc.

Alarm Relays:                             Five form "C" relays. These alarm
                                          relays can be "mapped" using the
                                          optional P.C. software.

Transmit Mute:                            The alarms that will cause the
                                          transmitter to mute are:
                                          Modulator
                                          LO/Synthesizer

Time Delay for TX Mute:
   Alarm recognition to Tx Mute:          less than * milliseconds
   Alarm Clearing to Tx Output Restoral:  * seconds

Resulting Power Reduction:                * dB


Section 8:     Loopbacks:                 Three types of loopbacks are offered:

   IDU Loopback:                          Loops the aggregate date before the
                                          "N" connector of the IDU. Tests all
                                          circuits in the IDU for operation. An
                                          external BERT set is needed to test
                                          for error performance. Traffic
                                          effecting on all tributaries.

   ODU Loopback:                   Used only with the Loopback Test Translator
                                   (LBT) to allow testing of an entire
                                   terminal. The LBT consists of a mixer and a
                                   1280 MHz oscillator.

   Link Loopback:                  Loops the far end tributary at the line
                                   driver and returns the E1 signal to the
                                   local end. Affects only the tributary
                                   selected. An external BERT set is needed to
                                   perform error rate tests.

        Training records are held for each employee registering their education,
        experience and training requirements.

8.18    SERVICING

        The design philosophy of products manufactured by the Company precludes
        the need for regular maintenance. Servicing procedures are therefore not
        required.

8.19    STATISTICAL TECHNIQUES - QAP 4.20(03.70.019)

        The Company promotes the use of statistical tools and techniques in a
        systematic way to continually reduce variation in processes, products,
        and incoming materials. The Quality Assurance Manager is the Statistical
        Coordinator for the Company.
