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 *** **** ******.

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.

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

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.

                                          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

   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.

8.11    INSPECTION AND TEST STATUS - QAP 4.12(03.70.012)

        The inspection and test status of product during the process and
        assembly stages of the operation is identified by unique routing card.
 
        A unique routing card is provided for each defined module, subassembly
        or product recording its progress through the manufacturing process and
        its conformance to inspection and tests performed.

        The Quality Assurance Manager is responsible for the release of
        conforming product.

        identification, segregation and disposition in accordance with
        documented procedures.

8.12.1  NON-CONFORMANCE REVIEW AND DISPOSITION

        In the documented procedures, the Quality Engineer is responsible for
        the review of Non-conformance Reports with other members of the Company
        Material Review Board to determine the appropriate disposition of non-
        conforming material and product.

        A Deviation Authorization may be requested from the customer for non-

        control the receipt and issuing of materials.

        Lists of materials requiring special storage conditions, or having a
        limited shelf life are maintained and controls applied to conform with
        requirements. The materials requiring special storage conditions are
        maintained in the appropriate environment and materials having limited
        shelf life are discarded in an approved manner when shelf life has
        expired. Material Safety Data Sheet regulations are applied for storage
        and handling of material. Lists of such materials are maintained.

8.14.4  PACKAGING

        Company Standards and Procedures control the marking and packaging of
        the product to ensure conformance to specified contract requirements.

8.14.5  DELIVERY

        After final inspection and test, documented procedures provide for the
        protection of the product in stores and during delivery to the customer.

        Delivery documentation is provided and instructions are carried out in
        accordance with specified contract requirements.

8.15    QUALITY RECORDS - QAP 4.16 (03.70.016)

        The quality records identified in the Quality Assurance Procedures are
        filed and maintained by the applicable department and are under the
        jurisdiction of the Quality Assurance Manager for demonstration of the
        Quality System effectiveness.

        The records are retained for a minimum of five years or for a period
        specified by customer contract.

8.16    INTERNAL QUALITY AUDITS - QAP 4.17(03.70.017)

        All quality activities are subject to a planned and documented audit to
        verify compliance with the defined Quality System.

        Audits are conducted at predetermined intervals and are carried out by
        trained personnel under the control of the Quality Assurance Manager.

        The results of these audits are recorded and used to improve the
        effectiveness of the Quality System.

8.17    TRAINING - QAP 4.18 (03.70.018)

        The Company maintains procedures for identifying the training needs of

        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
