ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 317 of the California General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Act").
Article VI of the Registrant's Amended and Restated Articles of Incorporation,
to be filed and effective upon completion of this offering (Exhibit 3.3 hereto),
provides for indemnification of its directors and officers to the maximum extent
permitted by the California General Corporation Law, and Section 6.1 of the
Registrant's Bylaws, to be effective upon completion of this offering (Exhibit
3.4 hereto), provides for indemnification of its directors, officers, employees
and other agents to the maximum extent permitted by the California General
Corporation Law. In addition, the Registrant has entered into Indemnification
Agreements (Exhibit 10.1 hereto) with its directors and officers containing
provisions that are in some respects broader than the specific indemnification
provisions contained in the California General Corporation Law. The
indemnification agreements may require the Registrant, among other things, to
indemnify its directors and officers against certain liabilities that may arise
by reason of their status or service as directors or officers (other than
liabilities arising from willful misconduct of a culpable nature), to advance
their expenses incurred as a result of any proceeding against them as to which
they could be indemnified, and to obtain directors' and officers' insurance if
available on reasonable terms. Reference is also made to Section 6(b) of the
Purchase Agreement contained in Exhibit 1.1 hereto, which indemnifies officers
and directors of the Registrant against certain liabilities.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

          and stock purchase rights to purchase an aggregate of 1,948,713 shares
          of common stock have been returned to Registrants's stock plans.

     (b) There were no underwritten offerings employed in connection with any of
the transactions set forth in Item 15(a).

     The issuances described in Item 15(a) were deemed to be exempt from
registration under the Securities Act in reliance upon Section 4(2) thereof as
transactions by an issuer not involving any public offering and in the case of
some issuances of our common stock, were deemed to be exempt from registration
under the Securities Act in reliance upon Rule 701 promulgated under the
Securities Act. The recipients of securities in each such transaction
represented their intentions to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the securities issued in such transactions.
All recipients had adequate access, through their relationships with the
Registrant, to information about the Registrant.

ITEM 17.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Act, the
     information omitted from the form of Prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in the form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be a part of this Registration
     Statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of Prospectus shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

ARTICLE 1 - MATERIAL

multipoint, wireless access network products as specified in Appendix C. Such
MATERIAL is hereby offered for sale by Supplier and may be purchased by Company
in accordance with the terms, conditions and specifications stated in this
Agreement. This Agreement is a non-commitment agreement and MATERIAL shall be
furnished by Supplier on an as-ordered basis.

The parties acknowledge that Company reserves the right to manufacture MATERIAL
covered under this Agreement and similar products in Company's own facility and
that the manufacture of such MATERIAL may have a substantial impact on Company's
future purchases under this Agreement. Company will give Supplier written notice

ARTICLE 3 - PRICE AND DISCOUNTS

39 GHz MATERIAL shall be defined as point to multipoint products designed to
operate within a system whose air interface is within the range of 39 to 40 GHz.
Non-39 GHz MATERIAL shall be defined as those products designed to operate
within a system whose air interface is outside this range.

Prices and discounts for 39 GHz and non-39 GHz products shall be as shown in
Appendix A. Prices and discounts as listed in Appendix A shall remain in effect
during the term of this Agreement. In addition, for non-39 GHz products,
Supplier agrees to furnish MATERIAL to Company on terms and conditions
(including price) as favorable as provided to any of Supplier's other
distributors with similar volumes of MATERIAL being purchased from Supplier. In
the event that the Company and the Supplier reach an agreement for Company
funding of an accelerated development of the Supplier's 39 GHz products,
Supplier agrees to furnish MATERIAL to Company on terms and conditions (not
including price) as favorable as provided to any of the Supplier's other
distributors with similar volumes of MATERIAL being purchased from Supplier. In
addition, for two years from the first commercial delivery of 39 GHz MATERIAL to
Company, Supplier agrees to supply 39 GHz MATERIAL to Company at a price at
least [***] lower than provided to any of the Supplier's other distributors with
similar volumes.

A target customer list is shown in Appendix D. Supplier agrees that MATERIAL
furnished to Company will be priced at least [***] percent ([***]%) below the
price at which Supplier furnishes MATERIAL to any direct end user customers on
the then current target list who make purchases of similar annual volume.
Customers may be added or deleted from the target customer list by mutual
consent of both Company and Supplier.


Discount Calculation:

For the purposes of calculating the pricing discounts under this Agreement, the
annual value for quantities of MATERIAL ordered by Company will be measured in
one-year intervals starting from the execution date of this Agreement. For
MATERIAL ordered by Company during each one-year period, for delivery within
that same one-year period, Supplier shall provide a pricing discount to Company
established at the maximum discount level for the maximum value for aggregate
quantities of MATERIAL to be ordered by Company. Discounts and values for
quantities of MATERIAL are shown on Appendix A. Should the total annual value of
Company's aggregate orders for MATERIAL, for delivery within that same one-year
period, covered under this Agreement fall short of the aggregate value of orders
established for Supplier's pricing discount, Company shall reimburse Supplier
for the difference in price between the price for quantities of MATERIAL ordered
at the lower discount level and the price invoiced to Company at the higher
discount level.


[***] CONFIDENTIAL TREATMENT REQUESTED

Notwithstanding the above, should Supplier be unable to deliver Company's
required quantities, per MATERIAL description shown in this Agreement and
ordered within the one-year interval periods stated herein, Company shall not be
required to reimburse Supplier the value for shortfall quantities shown in
Appendix A.

Price Revision

Prices shown in this Agreement shall be reviewed every six months after the
inception date of this Agreement for the purpose of mutually determining price
revision. In addition, should the parties mutually determine that prices should
be reviewed prior to the six months review period, either party may initiate a
review of prices under this Agreement by giving written notice to the other at
least sixty (60) days prior to the proposed effective date of such price review.
If the parties fail to agree upon revised prices by the proposed effective date
of price review, then at no obligation or liability to Company, Company reserves
the right to cease placing future orders with Supplier. Company's orders which
Supplier has in Supplier's possession shall be invoiced at current contract
prices.

ARTICLE 12 - QUALITY

(A)      Supplier commits to ensure that all manufacturing, and design
         operations, including any key sub-contractor, or contract manufacturing
         suppliers, which contribute to the design,


                                      -5-
<PAGE>   11
         development, production, delivery and service of material are ISO 9000
         registered by an accredited Registrar have an equal registration (in
         case of overseas supplier).

(B)      Supplier commits to having a continuous improvement program in place
         which will allow it to attain and maintain "acceptable" ratings (or
         equivalent) on all quality system elements per Supplier Capability
         Assessment (SCA), or other type of Company assessment, as periodically
         performed by Company. An "acceptable" element is defined as one where
         the quality system meets the "general intent" of the quality system
         element and is fully implemented to maintain the quality system and
         product quality. No significant deficiencies encountered that would
         jeopardize the quality system, and product quality and/or reliability.

(C)      Supplier commits to establish quality control (QC) verification points
         throughout the manufacturing process. These verification points should
         be located in-process as well as after MATERIAL has completed all
         manufacturing operations. The scope of these QC verification points
         shall be to valid through visual and mechanical inspections and tests,
         and with the use of statistically valid sampling plans, that MATERIAL
         conforms to Supplier's manufacturing, product and process
         specifications, standards of acceptable workmanship, as well as other
         specification's which may be provided by Company. Company reserves the
         right to review these QC points and make suggestions for improvement.
         Supplier commits to address these suggestions through the
         implementation of appropriate corrective actions.

(D)      Supplier commits to establish an end of the line Quality Assurance
         product audit on material by 12/1/98. The focus of this audit shall be
         to replicate user application of MATERIAL as specified by Company's
         customer. Test and examination of MATERIAL under the quality audit
         shall be at a system level, and shall include but is not limited to:

         a)       Exercising said MATERIAL over the full spectrum of temperature
                  ranges over which MATERIAL is designed to operate.

         b)       Full operation of MATERIAL over a period of time not less than
                  to ensure best practice and quality.

         c)       A system for continuous monitoring of all primary and
                  ancillary product functions and fault detection of the
                  MATERIAL while under this test.

         Supplier shall continuously review customer return data to ensure that
         the scope of the product quality assurance audit function includes the
         requirement(s)/condition(s) under which the return failed.


                                      -6-
<PAGE>   12
         Supplier shall perform a detailed failure mode analysis of all MATERIAL
         found defective through the quality assurance audit in line with the
         requirements and process outlined in paragraph F.

         Supplier agrees to provide to Company on a monthly basis, results of
         the quality assurance product audit in a format specified by Company.

(E)      Supplier commits to establishing a program of tracking return rates.
         The following is the suggested method for tracking, calculating, and
         tracking customer returns. Company and supplier may mutually agree to
         modify this method as appropriate. MATERIAL which has been in operation
         for any period of time up to, and including one full year shall be
         considered part of this tracking program. For the purpose of this
         article, the term "product" shall be used to define the lowest
         replaceable unit (lru) of MATERIAL supplied to Company.

         For the purpose of calculating the return rate, the following
         definitions apply:

         RTM(x) = The quantity of lru's which were manufactured in the Target
         Month;(x) that have been returned during the period beginning the 4th
         month after the Target Month and ending the 15th month from the Target
         Month.

         PTM(x) = The total number of lru's in the Target Month;(x).

         All returns will be included in the calculation of the return rate
         including, but not limited to, failures, no trouble founds, and
         recalls.

         A Target Quarter Return Rate (TQRR) is to be calculated using the
         following equation:

         TQRR = 10,000 x [[RTM(l)+RTM(2)+RTM(3)]/[PTM(l)+PTM(2)+PTM(3)]]

         Where:

         "(1)" refers to the first month of the Target Quarter "(2)" refers to
         the second month of the Target Quarter "(3)" refers to the third month
         of the Target Quarter

         This calculation shall be made on a quarterly basis for the product
         manufactured under this contract.


                                      -7-
<PAGE>   13
         The Supplier agrees to update and report TQRR's on a quarterly basis to
         Company, and to comply with the Annual Return Rate (ARR) requirement in
         accordance with the following schedule:

<TABLE>
<CAPTION>

</TABLE>

         The ARR is 10,000 times the summation of the number of returns received
         for the Target Months of the Manufacture Year divided by the summation
         of the manufacturing populations for the Target Months of the
         Manufacture Year. Supplier commits to provide to company on a monthly
         basis, the cumulative year to date results of the ARR until the annual
         measurement requirement is due.

(F)      Supplier commits to establishing a system for tracking and analysis all
         MATERIAL returned by Company to it, as well as any MATERIAL failures
         which occur through the company's end of the line quality assurance
         audit. For all MATERIAL in the above two categories, supplier shall
         perform a failure mode analysis, which at a minimum will be down to the
         component level. Component level failure modes will be recorded, and
         failed components found defective will be accumulated for the purpose
         of determining repetitive occurrences.

         Material shall be considered defective if it fails to meet the warranty
         specifications under this Agreement (including performance and
         appearance Specifications) or if during customer testing, installation,
         or use, the MATERIAL fails to operate as expected or specified.

         If the analysis of a Company return is found to be within the
         specifications of this agreement (i.e., a no trouble found condition),
         then Supplier shall track these no trouble found conditions and notify
         Company of said findings at a minimum of a monthly interval, so that
         appropriate investigative measures may be taken to determine the root
         cause.

(G)      If a Target Quarter Return Rate (TQRR) is found to exceed the
         applicable ARR requirements specified in paragraph E, or repetitive
         occurrences are observed with regard to component level failures then
         the supplier shall provide a written Corrective Action Report to the
         Company, explaining in detail the nature of the problem detected, and
         the


[***] CONFIDENTIAL TREATMENT REQUESTED

         step(s) Supplier proposes to correct the problem. As part of the plan
         to correct the problem, it is agreed that the Supplier shall:

         a)       Incorporate the remedy in affected MATERIAL.

         b)       Ship all subsequent MATERIAL incorporating the required
                  modification correcting the problem at no additional charge to
                  Company; and

         c)       Repair and/or replace previously shipped MATERIAL that may
                  contain the same problem trend. In the event that Company
                  incurs costs due to such repair and/or replacement, including
                  but not limited to labor and shipping costs, Supplier shall
                  reimburse Company for such costs. Supplier shall bear risk of
                  in transit loss and damage for such repaired and/or replaced
                  MATERIAL.

         Supplier and Company shall mutually agree in writing as to the
         implementation schedule of the corrective action plan. Supplier agrees
         to use its best efforts to implement the plan in accordance with the
         agreed upon schedule. It is also agreed that the Company shall be
         entitled to postpone at no charge to Company, further deliveries of
         orders until such time as the remedy is implemented consistent with
         this Article.

(H)      As part of a program of continuous improvement, Supplier agrees to
         establish annually, improvement goals for a series of key quality
         objectives. These goals should include, but are not limited to a)
         customer return rates as specified in Article E, b) Quality Assurance
         product quality audit defect rates, c) final system test yields.
         Supplier agrees to track these goals on a monthly basis, and to commit
         the resources necessary for the attainment of these goals.

(I)      The following paragraph Summarizes the requirements for providing data
         and information to Company as per paragraphs A through H.

         a)       The receiving party shall use Information only for the
                  Purpose, shall hold Information in confidence using the same
                  degree of care as it normally exercises to protect its own

<PAGE>   29
                  need to know; provided that by doing so, the receiving party
                  agrees to bind those consultants and contractors to terms at
                  least as restrictive as those stated herein, advise them of
                  their obligations, and indemnify the disclosing party for any
                  breach of those obligations.

         b)       Upon the disclosing party's request, the receiving party shall
                  either return to the disclosing party all Information or shall
                  certify to the disclosing party that all media containing
                  Information have been destroyed. Provided, however, that an
                  archival copy of the Information may be retained in the files
                  of the receiving party's counsel, solely for the purpose of
                  proving the contents of the Information.

         a)       was independently developed by or for the receiving party
                  without reference to the Information, or was received without
                  restrictions; or

         b)       has become generally available to the public without breach of
                  confidentiality obligations of the receiving party; or

         c)       was in the receiving party's possession without restriction or
                  was known by the receiving party without restriction at the
                  time of disclosure; or

         d)       is the subject of a subpoena or other legal or administrative
                  demand for disclosure; provided, however, that the receiving
                  party has given the disclosing party prompt notice of such
                  demand for disclosure and the receiving party reasonably
                  cooperates with the disclosing party's efforts to secure an
                  appropriate protective order.

8.       Access to Information hereunder shall not preclude an individual who
         has seen such Information for the purposes of this Agreement from
         working on future projects for the receiving party which relate to
         similar subject matters, provided that such individual does not make
         reference to the Information and does not copy the substance of the
         Information during the Confidentiality Period. Furthermore, nothing
         contained herein shall be construed as imposing any restriction on the
         receiving party's disclosure or use of any general learning, skills or
         know-how developed by the receiving party's personnel under this
         Agreement, if such disclosure and use would be regarded by a person of
         ordinary skill in the relevant area as not constituting a disclosure or
         use of the Information.

9.       As between the parties, all Information shall remain the property of
         the disclosing party. By disclosing Information or executing this

                        capabilities, installation, enhancement requests or
                        configuration. There is clearly little or no impact to
                        the Customer's business operation. Netro is willing to

                        developments to resolve requests for improvement by the

                an RMA number, and will be cleared by a resolution and
                description of the cause, which will also be documented by
                Netro. Netro's RMA process is initiated by contacting the Netro
                Technical Assistance Center. The Reseller and the Customer are
                responsible for the proper packaging and the payment of shipping
                related fees for shipment of the product of Netro. Netro is
                responsible for the proper packaging and payment of shipping

                           WARRANTY ELIGIBILITY SYSTEM
                                   TRANSACTION

The Warranty Eligibility System (WES) tracks a serialized product from
manufacturing to the customer and provides up-to-date information about the
product's warranty status. In order to accomplish this, WES receives data from
entities whose functions affect an item's warrantability.

At the end of the manufacturing, shipping, or repair processes, information
about an item will be sent to WES for inclusion on the Warranty Database. This
file can be sent to WES using

1)      UNIX file transfer at,

        /ust/pool/uucppuplic/receive/wes/origsystem/WESXXNNNN where origsystem
        is the UNIX machine originating the file XX is a location code entry in
        location table and NNNN is the sequence number on the header record.

2)      or electronically sent to,

        abcod!wesrcl

3)      or via internet,

        !rlange

4)      or by placing the file on a floppy disk and mailing the disk directly to
        the WES group at:

        Lucent Technologies, Inc.
        Westwood of Lisle
        Attn:  A.L. Fitzgerald
        2443 Warrenville Road
        Lisle, IL  60532

Batch files received for processing by WES must be processed by a Header Record
as attached. Following the Data Records must be a Trailer Record also attached.
The Header and Trailer Records are interrogated by WES and messages are returned
to the sending location indicating the status of each file transmitted to WES.

These files should be sent at least once a week, depending on volume, in order
to keep the database current. That data needs to be formatted as shown on the
following page.

                        Addendum 1 to Contract GN11980056

Agreement No. GN11980056 between Netro Corporation ("Supplier") and Lucent
Technologies ("Company") is hereby amended as follows:

Both Company and Supplier agree to accelerated production schedule for 39 GHz
point-to-multi point radios.

~   Company agrees to fund Supplier per Attachment A1.
~   Supplier agrees to deliver product per Attachment A1.

Effective October 15, 1998 the following clauses are hereby added to the
agreement.

TERMINATION - For purposes related exclusively to the accelerated development of
the 39 GHz point-to-multi point radio, Company may terminate accelerated state
of business relationship in whole or in part by giving Supplier at least 30 days
prior written notice but not before item 4 listed on Attachment A1. Prices for
any work remaining with Supplier under this Agreement terminated in part may be
adjusted to fairly reflect Supplier's costs resulting from work withdrawn. Upon
termination, Company shall pay Supplier all amounts due for services and
material, if any, provided by Supplier to Company under this agreement up to and
including the effective date of termination. Such payment will constitute a full
and complete discharge of Company's obligations under this Agreement.

In the event that Lucent terminates the Agreement prior to shipment of the 39GHz
product to Lucent's customers, Netro agrees to pay a rebate to Lucent from its
sales of the 39GHz radios. The rebate will be paid at the rate of [***] of the
net sales of the 39GHz radios up to a maximum rebate of Lucent's funding prior
to termination. The rebate of funding shall survive the original OEM agreement
in time if Lucent's funding has not been fully rebated. If Company terminates
the accelerated development of 39GHz product, Company will not recognize any
preferred pricing as described in Article 3 of the OEM agreement for 39GHz
product.

<PAGE>   86
Lucent agrees that it will provide a $[***] minimum order to Netro for 39
GHz products as soon as it is able to do so but no later than December 31, 1998.
Lucent realizes that unless a firm order of at least $[***] dollars is
placed for 39GHz equipment, there is no economic justification to continue the
development effort beyond the prototype stage. Hence in the absence of a firm
order of at least [***] dollars, it is the intention of both Lucent and
Netro to halt the 39 GHz development effort after the completion of the
prototype

All other terms and conditions as stated in the original contract remain
unchanged.

                QUALITY ASSURANCE CHARACTERISTICS AND CONDITIONS



Netro's quality program is an integral part of Netro's business process and is
involved in all aspects of the activities that occur within Netro on a daily
basis. In the area of Netro products, the quality program starts at the earliest
phase in the new product design and progresses throughout the life cycle of the
product. It includes design control's and evaluations, manufacturing readiness
evaluations prior to release for manufacture, full documentation of all parts,
materials and processes, material and vendor testing and controls, full product
evaluation and testing prior to shipment to the end users, and a complete
customer service activity to resolve any issues that may occur after shipment.

Netro's quality program is based on ISO-9001 Quality System Requirements and
Netro has been registered by the British Standards Institute (BSI) after having
been evaluated through an exhaustive set of audits to those requirements.
Netro's registration number is #xxxxxx, and this initial registration was
received in March of 1997. Since that time, Netro has had a follow-up six month
audit by BSI and successfully passed this additional evaluation. Continuing
audits of the Netro system can be expected to be completed on a six month basis.

In addition to the BSI registration, Netro has been evaluated and audited by the
British Approvals Board for Telecommunications (BABT) and has received their
Full Quality Assurance Approval (FQAA) so that Netro quality system and testing
procedures have been approved for testing of the Digital products produced by
Netro. FQAA approval was received after a comprehensive audit of Netro's quality
system that was similar in content and thoroughness to the ISO registration
audit. This approval was also received in March of 1997 and since that time,
Netro has had a successful follow-up audit which allows for continuation of
Netro's FQAA approval.

To assure that all products produced by Netro meet the requirements specified by
Netro's product specifications or the special requirements imposed by Netro
customers, Netro has implemented a comprehensive system of quality assurance
analysis and test that starts at the earliest part of the production process:

- -    Components are carefully selected to assure that their performance had been
     proven in the environments that Netro's products will see in use. Custom
     parts and Materials are specially tested and evaluated by Netro to assure
     reliable performance. To the extent possible, Supplier Quality Systems must
     meet the requirements of ISO-9000. When this is not possible, Netro
     evaluates the Supplier systems to assure that their approach to quality
     assurance provides products that meet all applicable requirements.

- -    Material received by Netro, is evaluated upon receipt to see that it meets
     specified requirements. Material that is found to be discrepant is
     evaluated to identify the specific problem found and the supplier contacted
     to determine the corrective and preventive action that must be taken so
     that defective material is not received in the future.

- -    As product moves through the production line, it is evaluated by trained
     production operators to assure that it meets all of the quality
     requirements necessary for acceptable product performance. An on line
     quality information system (Quality Feedback System) is utilized to
     maintain the data associated with evaluations and test. Each step in the
     production process is entered into QFS by the use of bar codes, and if any
     step should be missed, or has defects associated with it, the system will
     prevent the product from moving on in the production flow. Data from this
     system is utilized to analyze failure modes and to establish the corrective
     and preventive actions necessary to eliminate the problem.

- -    At the system level, products are subjected to a wide range of tests and
     evaluations to assure that they will work in the customers applications.
     These tests include Environmental Stress Screening (ESS), electrical
     performance tests, calibration tests, and any other tests and evaluations
     deemed necessary to assure superior performance. Burn-in tests and other
     tests necessary to weed out early failures are conducted at various levels
     of the production cycle.

- -    All products are packaged in specially designed materials and containers
     that have been tested to assure that they will survive the rigorous and
     difficult environments that are seen in transporting and handling Digital
     Radio products.

Continuous improvement and total customer satisfaction are the cornerstones of
Netro's quality system and reflect the major content of Netro's quality policy.
Continuous improvement is a way of life at Netro. Not only improvement in the
quality of the products Netro produces, but improvement in product performance,
in Netro's business systems, and overall service to the customers. In its drive
to achieve total customer satisfaction Netro has fully staffed a Customer
Services Organization that responds to customer requirements and issues as they
occur. This organization stands ready to respond to Customers requests as they
arise and is continuously seeking ways of improving overall service.

Netro's Quality Assurance Manual has been written to reflect the actual
operating methods employed by Netro during all phases of its business and
product life. This manual describes all parts of the Netro quality Assurance
System and is available for review by customers. If forms the basis for a
comprehensive system of documents that describe the actual procedures that are
used by Netro personnel in the performance of their duties. Employee's are
thoroughly trained in all aspects of the Quality Manual and the Company
Operating Procedures and part of each employee responsibility is to understand
and use Netro's quality policy and overall quality system. This well trained and
competent work force assures Netro customers of superior radio products.

Netro will also deliver a copy of its quality manual to Italtel promptly when it
is available.

            ITALTEL - NETRO CORPORATION PROBLEM PRIORITY DEFINITIONS



PROBLEM PRIORITY DEFINITIONS:

Priority 1:          An existing network or link is inoperable or there is a
                     situation that causes Critical impact to the Customer's
                     business operation. Italtel is providing Tier II support
                     and requests assistance from Netro. Italtel, Netro and the
                     customer will commit full-time resources to resolve the
                     situation. The situation may be resolved by a fix, a
                     workaround, an upgrade to the software, or an operational
                     change that allows the customer to gain operational
                     stability.

Priority 2:          The operation of an existing network or link is severely
                     degraded, or significant aspects of the Customer's business
                     operation are being negatively impacted by unacceptable
                     hardware or software performance. The customer is able to
                     maintain operations but in a severely degraded manner.
                     Italtel is providing Tier II support to the customer and
                     requests assistance from Netro. Italtel, Netro and the
                     Customer will commit resources as deemed necessary to
                     resolve the situation. The situation may be resolved by a
                     fix, a workaround, an upgrade to the software, or an
                     operational change that allows the customer to gain
                     operational stability.

Priority 3:          Operational performance of the network is impaired while
                     most business operations remain functional. Italtel, Netro
                     and the Customer are willing to commit resources during
                     Standard Business Hours to restore service to satisfactory
                     levels. The situation may be resolved by a fix, a
                     workaround, an upgrade to the software, or an operational
                     change that allows the customer to gain operational
                     stability.

Priority 4:          Information or assistance is required on Netro product
                     capabilities, installation, or configuration. There is
                     clearly little or no impact to the Customer's business
                     operation. Netro and Customer are willing to provide
                     resources during Standard Business Hours to provide
                     information or assistance as requested. If a fix or
                     workaround is deemed necessary, it may be provided in a
                     later release of the software or the Customer may be
                     requested to upgrade to a higher level of software to
                     resolve the issue.

Feeder Product for the Feeder Market, the characteristics and specifications of
which are described in Annex 1 hereto.

        1.02. Since the Feeder Product shall be developed by adapting and using
as a basis the Netro PMP Product (AIRSTAR), in the event that third party's
software is used in the Netro PMP Product, Netro warrants to Italtel that such
third party's software is available on commercially


                                      -4-
<PAGE>   5
reasonable terms and will not prejudice in any way Italtel rights under this
Supplemental Agreement.

        Netro will provide access to the third party's software at the same
price and conditions obtained by Netro.

        Netro further warrants that it owns or has rights to all intellectual
property necessary for the development and manufacture of AirStar and the Feeder
Product, free and clear of any adverse claims of any third party.

        1.03. In order to integrate the Feeder Product with the Network
Management Systems used by Italtel, Italtel will develop and manufacture for its
own exclusive use the necessary Interface Cards.

2.      JOINT DEVELOPMENT PROGRAM.

        2.01. The Parties shall carry out and complete the development
activities under this Supplemental Agreement in accordance with the Joint
Development Program, as better defined in 2.03. below.

        The first release of the Feeder Product is targeted for July 1998.

        2.02. The above mentioned development activities of the Feeder Product
shall be carried out under the guidance of the Committee - Product subdivision,
with participation of both Parties' R&D personnel.

        2.03. The detailed Joint Development Program (including planned
development efforts and activities, development time schedule, list of Italtel
and Netro information that may be


                                      -5-
<PAGE>   6
useful or necessary for the carrying out of the activities, etc.) is hereto
attached under Annex 2.

        From time to time the Joint Development Program will be updated to cover
product modifications, as required by the market, that will be authorised by the
Committee.

        2.04. The Parties recognize that time to market is essential for the
success of the program; should the program suffer unexpected delays, the Parties
will promptly meet to identify remedies. Should the completion of the Joint
Development Program suffer - for reason not attributable to a Party - a delay
which is likely to prejudice the success of the Feeder Product in the market -
and should the Parties fail in good faith to identify appropriate remedies, then
either Party shall be entitled to withdraw from the Joint Development Programme
without incurring any liabilities towards the other Party.

3.      CONTRIBUTION OF THE PARTIES.

        The allocation of tasks, as defined by the Committee Product Subdivision
and approved by the Parties pursuant to Article 5.02.(a) of the Frame Agreement,
is that specified in Annex 2 hereto attached.

        Each Party will bear the expenses associated with its own tasks.

4.      OWNERSHIP AND EXPLOITATION.

        4.01. Each Party shall retain the ownership of its Existing Information.
Each Party shall license to the other Party the necessary information to enable
it to manufacture, modify and sell (under trade marks and logos of its own
choice) the Feeder Product within the Feeder Market; this will include the right
to have a third party manufacture the Feeder Product, provided that
manufacturing by anyone other than an Affiliate of Italtel will require the
consent of Netro in the Committee, which consent will not be unreasonably
withheld.

        The above mentioned licence shall be personal, irrevocable -- except if
terminated due to the licensed Party under Article 13.02 (a) or (b) of the Frame
Agreement-- non-transferrable, non-exclusive. Rights of each Party with respect
to Existing Information of the other Party after termination/expirat are
specified in Article 13.04 of the Frame Agreement.

        4.02. Netro and Italtel shall jointly and severally own the Joint
Developed Information, if any.

        The right to use the Joint Developed Information outside the Feeder
Product by either Party must be approved by the Committee on a case by case
basis.

        4.03. Italtel agrees not to exploit its manufacturing rights of the
Feeder Product until reaching a cumulative amount of [***] of Products
purchased from Netro,

2       BACKGROUND

2.1     THE BUILDING BLOCKS OF A WIRELESS MOBILE SYSTEM

        A Mobile Feeder Network is a point to multipoint (PNP) microwave network
        that interconnects digital traffic of mobile base stations to a mobile
        base station controller.
        The network main building blocks are depicted in Figure 2-1. A group of
        mobile base stations serves GSM mobile telephones. The traffic is fed
        via E1/T1 line to a Terminal Station (TS) which is realized as an
        integral ODU equivalent to AirStar SAS+RU. Other TSs are located next to
        other mobile base stations in the same geographical area served by a
        central station sector antenna attached to a CRU (similar or identical
        to AirStar BRU). One or more CRUs are attached by a coax to a Central
        Station Shelf (CSS), the equivalent of an AirStar BSS).

        The mobile traffic is delivered from the CSS to a mobile Base Station
        Controller (not to be confused with the AirStar BSC) that is connected
        to the Mobile Switching Center and the PSTN.

        The CSS is a rack-mounted system consisting of a Central Sector
        Controller (identical to AirStar BSC), and a Central Modem Unit (CMU),
        which is similar to AirStar BMU, but includes also E1/T1 ports.

2.2     AIRSTAR VS. FEEDER NETWORK TERMINOLOGY

Unfortunately, the term "Base Station" has different meanings in a mobile
network context and the AirStar system. To retain the mobile terminology, the
feeder network components are renamed, even if they are identical, as shown in
Table 2-1.

3.      SYSTEM SPECIFICATIONS

3.1     TRAFFIC TRANSPORT DEFINITION

Each Mobile Base Station may require n = 2 to 31 64 kbit/s (DS0) channels. In a
GSM application, each channel consists of 4 x l6 kbit/s sub-channels, one of
which may be a "D" channel. The Feeder transports the nxDS0 channels
transparently, regardless of signaling content. Base Stations i and j may have
ni and nj channels, respectively, and in general, ni needs not be equal to nj.

The n channels are provided at the mobile base station as fractional E1/T1. Only
n out of the full line capacity is forwarded to the mobile BSC. The air
interface will transmit only the n provisioned channels but these provisioned
channels are always transmitted, whether active or not. The n channels need not
be contiguous. The n-channels are full duplex. These channels are delivered as
E1/T1 interfaces at the CSS to BSC interface, such that each E1/T1 line is an
aggregate of multiple base stations traffic. The mapping of DS0 channels is such
that all channels from one BS terminate in the same E1/T1.

 The bandwidth provisioning is semi permanent. A change requires human
intervention via NMS and is considered to be an non-frequent event. A change in
capacity will interrupt the service for that particular mobile base station.

These specifications are summarized below.

3.4     TERMINAL STATION

The TS is an outdoor unit including the radio section and El/T1 interface. It is
equivalent to a single box containing the AirStar SRU and SAS, however only one
El/T1 is required as an interface. The El/T1 is lightning protected.

The TS includes the functions of the SAS digital card (Subscriber Interface
Card), excluding unneeded stuff options, but the card is modified to the outdoor
temperature range. It is TBD whether the SIC card will be used as-is or it will
be redesigned for a new form-factor.

The TS includes also the SAS modem card, which is de-stuffed for unneeded
functions, such as the coax multiplexer and telemetry (radio control) modem.

The rest of the TS is the SRU function, which includes most of the AirStar
modules unchanged. Two modules that can be slightly depopulated are the Radio
Unit Controller (RUC) and If module.

The TS will have an integral Lens-horn antenna compliant with ETSI for the 26
band, and an optional 390 mm parabolic-reflector antenna, that may use a
different TS enclosure than the lens-horn. For 10.5 GHz bands an ETSI-compliant
flat antenna will be used.


                                      3-13
<PAGE>   25
The polarization can be either vertical or horizontal. A field setting of
polarization is desired, but a factory setting is acceptable. The current
elongated shape of the SRU is desired to be maintained with the TS, although it
may be enlarged to accommodate the extra hardware.

No local craft interface is required, however the design will allow optional
RS-232 port. This port will be used for trouble shooting purpose, not for
configuration and not on a permanent basis.

The TS will have optional 1:1 protection switching option including switching of
the El/T1 port.

A backup control unit will be developed to provide both battery backup and E1/T1
switching for the mobile base station.

3.5     CENTRAL STATION

The Central Station is located normally next to a mobile BSC. It provides access
at increments of 4xE1/T1. The main building blocks are;

Central Station Shelf (CSS) consisting of a card cage (identical to a Cisco Axis
Shelf), and including AC or DC redundant power supplies and fan-cooling shelves.
This card cage can host the CSC (identical to AirStar BSC) card.

The first generation CSC card has two channels, each supporting 4xE1/T1 payload.
The CSC uses one channel for communication with a modem unit (CMU) that is
attached to a CRU (identical to a BRU). The other channel in the CSC is
connected to a second port in the CMU. This port is converted to four local
El/T1 interfaces by a card identical to an existing SIC Card, via a digital
adapter ("Null Modem").

The CSC must redirect the wireless traffic to the local E1/T1 ports at the SIC
card. This is done by the ATM switching function of the CSC.

A local l0BaseT port is used for local craft and NMS access.

The CSC-CMU-CRU group is subject to 1:1 redundancy, and they can be switched
with the El/T1 lines. The El/T1 lines switching is TBD.


                                      3-14
<PAGE>   26
The CMU is a rack mounted box. A future product release will allow to plug the
CMU directly to the CSS.

A co-located TMN adapter converts the l0BaseT SNMP traffic to CMIZE/Q3 traffic.

3.6     CENTRAL STATION RELEASE 1

The configuration of release 1 is depicted in Figure 3-1. It consists of the
following components:

A Cisco Axis Shelf (same as AirStar Access application, but used mostly as a
card cage),

Cisco ASC cards. The ASC card provides mass storage, synchronization and NMS
access. The ASC card will not be required in future releases that do not use the
Axis shelf.

A CSC card, Axis plug-in module, identical to the AirStar Access product, with 2
channels, each 8 Mbit/sec capacity. The CSC is further discussed below.

A CTU (Central terminal Unit), a rack mounted module for converting two BSC
channels to 8 El lines. The CTU is similar in function to two SAS units in the
Access product.

A CMU - a rack-mounted [***] including [***]-channel RF modem. In release 1
[***] channel is in use per CCS card, however the other channel is available
foe a [***] BSC or for the future [***] CSC.

The CRU is the same 26 GHz product as the BRU in the Access project. It uses a
90~ antenna to cover a sector or a corner of a square cell.

Each CSC has a 10 Base T port for NMS access. Future releases will convert these
ports by extra hardware and software to a TMN interface.

A RS232 interface runs through the ch-2 port of the CSC to the CMU and from the
CSC to the CTU, thus the two CSC cards can communicate both via the 10 Base T
and they have control of the CMU and CRU for redundancy switching.

The main differences in release 2:

The CSC is replaced by an identical function that does not require an Axis shelf
and an ASC card. The new unit is rack mounted, has [***]) and is called BUNI
(for Base-User Network Interface). The BUNI also includes a port for fast
redundancy switch using the direct port.

Subsequent BUNI and CMU releases will also support 16 QAM.

The CSC includes some functions that are not necessary for the feeder
application. Over time, these functions will be de-stuffed for cost reduction.
The main elements are:

CellMAC Controller for controlling the MAC air interface (including framing,
FEC, timing).

Request Grant Processor for coordinating the air interface activities.

ATM Cross connect for switching local traffic and user traffic.

A CPU, PCI interface and l0Base T interfaces.

While there will be several versions of the SIC card, the above \block diagram
depicts the typical implementation.

CellMAC ASIC controls the MAC layer, scrambling, REC and ATM conversion (AAL1
and AAL5).

A CPU control the system, running the VX-Works operating system, local
configuration, MAC management and the SNPM agent.

Four E1/T1 or T1 (stuff options) provide the line interfaces.

Two serial ports provide a test port and a telemetry port controlling the radio.

The modem interface includes data/clock lines and a control bus.

The evolutionary steps are:

The CSC release 1 is 2 channel 4-QAM for 7 MHz (ETSI) and 10 MHz (FCC) channel
spacing. Release 2 is 4 channel, 16 QAM 7 MHz (ETSI) and 10 MHz (FCC). The CSC
is changed to a rack mounted BUNI.

the CRU and TS release 1 are 26 GHz band. Future release is for 10.5 GHz channel
and US bands (TBD).

The CMU is a [***], [***], [***] QAM. It will evolve to a Dual [***] QAM modem
BMU card, and a SMU card (dual [***]) in release 2.

1.   PERIOD OF AGREEMENT

This agreement is entered into as of May 31, 1998 between Solectron California
Corporation whose principal place of business is located at 847 Gibraltar Drive
Milpitas, California 95035 (Supplier) and Netro Corporation whose principal
place of business is located at 3860 North First Street, San Jose, CA 95134
(Netro). This contract shall begin on the date of signing of the Agreement, and
shall terminate thirty-six (36) months from that date unless terminated or
renewed per other terms of the Agreement. Contract renewal discussions will
begin at least six (6) months in advance of the contract termination date. It is
the intent of the parties that this Agreement shall prevail over the terms and
conditions of any purchase order, acknowledgment form or other instrument.

2.   PRODUCTS, PRICES & QUANTITIES.

2.1  PRODUCTS TO BE PRODUCED. Supplier agrees to supply to Netro throughout the
term of this Agreement, any mix of the items listed in Appendix "A" at the
prices agreed to in writing by the parties. Other Products may be added to
Appendix "A" once Netro and Supplier have reached written agreement.

2.2  PRODUCT DEFINITION. At the start of this Agreement, Supplier shall produce
the Products defined in Appendix "A" exactly to the drawings, specifications,
and documentation provided by Netro and agreed to in writing by Supplier unless
otherwise approved in writing by Netro. Only the suppliers shown on the Approved
Vendor List ("AVL") provided by Netro shall be utilized for the initial
procurement of materials. Supplier shall have the right to submit revisions to
Netro to the AVL and Bill of Material ("BOM") so that cost reductions shall be
achieved. Such revisions may include, but not be limited to design changes,
manufacturing technology improvements, development of new vendors, etc. All such
changes submitted by Supplier shall be approved in writing by Netro, prior to
implementation of the changes and Netro shall have the unlimited right to use
such changes, in any way it deems appropriate and at its sole discretion.

2.3  COST REDUCTION. Supplier shall implement an ongoing cost reduction program
(including material and productivity improvements) that will target an
annualized cost reduction of a minimum of [***] per cent ([***]) per Quarter for
Appendix "A" Products. Each cost reduction year will start at the signing of the
Agreement and continue until the anniversary date of the Agreement, then a new
cost reduction year will start. Netro will support this cost reduction effort
and will work closely with Supplier to achieve the targeted results. Changes to
meet the cost reduction goals will be mutually agreed to in terms of
implementation timing, effect on inventories, value of the cost reduction,
overall total cost savings, etc. Supplier shall retain the savings of Supplier
generated cost reductions within the quarter that they occur and will be
reflected in the quoted Product costs at the quarterly progress review meeting,
then such savings shall revert fully to Netro. Cost reductions developed solely
by Netro shall be fully retained by Netro. Each cost reduction activity
associated with material or design changes will be authorized by a Netro
generated and approved Engineering Change Order (ECO). The ECO will document the
initiator of the cost reduction, i.e., Netro or Supplier, and the change in the
Product cost to Netro resulting from the cost reduction. Cost reductions may
include but not be limited to reductions in Supplier margins, labor rates,
overheads, G & A's, etc. as driven by efficiency improvements, volumes or total
revenues. At each quarterly progress review meeting, a summary of cost reduction
activities and results will be presented by Supplier.

Netro or Supplier.

4. PRODUCT ORDERING

4.1 FORECAST. Netro will provide a six (6) month rolling shipment forecast each
month and a twelve (12) month shipment forecast each quarter. These forecasts
shall be by item part number and shall include anticipated delivery date,
quantity to be delivered, etc. and are non-binding best estimates of Netro's
future needs. However, if Netro falls short of this goal by the end of the term
of this Agreement, or cancels this Agreement, there shall be no bill-backs or
other retroactive price increases associated with the shortfall or cancellation.

4.2 PURCHASE ORDERS. Netro's initial purchase order for each Product shall be
for sixty (60) days of Product shipments which will set forth the ordered
types, quantities & required delivery dates of the Products to be produced. Each
month, Netro will release an additional thirty (30) days of Product, which will
be, to the extent possible, based on the forecasts provided above. Upon receipt
and acceptance of Netro's purchase order or material release, Supplier will be
obligated to sell and deliver the Products in accordance with the quantities
and delivery dates specified by the purchase orders or releases. Purchase order
releases will be provided to Supplier by Netro within ten (10) working days
after the end of each calendar month.

4.3 QUANTITY & DELIVERY CHARGES. Purchase orders for existing Products can
deviate from forecast or purchase order as follows:

          a.   Within 30 Days - plus or minus [***]
          b.   Between 31 and 60 Days - plus or minus [***]
          c.   More than 60 Days - plus or minus [***]

where the total charge for the quarter is plus or minus [***] per cent [***].
Any change requested by Netro beyond the allowable increase/decrease shall be
handled by Supplier on a reasonable commercial efforts basis subject to material
availability, capacity availability and agreed upon Product testing
requirements. If the volume exceeds [***] Product units per month, Netro and
Supplier agree to review these percentages at the quarterly progress review
meetings and adjust them to then current business requirements. Should Netro
insist on keeping this high degree of flexibility for unit volumes exceeding
[***] per month the parties will negotiate in good faith a reasonable carrying
charge for such excess inventory.

From time to time, Netro may request Supplier to carry or have on order certain
strategic components, subassemblies, or assemblies (collectively "Strategic
Materials") at higher levels than required in this clause. In this case, Netro
would be responsible for the carrying cost of Strategic Materials.

7. ACCEPTANCE & INSPECTION.

The basis for acceptance of the Products on this order shall be full conformance
to the drawings, specifications and test criteria as stated on Netro's
documentation provided to Supplier. Supplier will satisfactorily meet a minimum
of IPC610 Class II quality standard for all Products. Netro or its customers
may elect to source inspect Products and/or test data and results before
delivery from Supplier. Netro must accompany Netro customers while at Supplier's
facilities. Supplier will provide reasonable space for the source inspector.
Supplier will provide Netro five (5) working days advance notice of Product
availability for source inspection and Netro agrees to source inspect said
Products within five (5) working days after such notification. When Netro elects
to perform source inspection at Supplier's facility, final acceptance shall
occur at the time of source inspector's acceptance of Product, provided however,
that the mere review by Netro of performance data, test results and
manufacturing processes and consultation with Supplier's employees by Netro
regarding such information shall not be deemed to be a Source Inspection
hereunder. Netro may elect to inspect delivered Products one hundred per cent
(100%) or on a sampling basis. Any lot failing to meet the mutually agreed upon
sample inspection lot rejection criteria may be returned to Supplier for one
hundred per cent (100%) inspection, at Supplier's expense, if so desired by
Netro. Netro will notify Supplier of rejection of any Products in writing
within two (2) working days after rejection. Supplier may elect to have the
Products returned to them for evaluation, or with Netro's concurrence, have
Netro repair the Product at Supplier's pre-approved cost. Any Products returned
to Supplier shall be handled per Supplier's Returned Material Authorization
procedure. Products returned to Supplier for evaluation and/or repair shall be
repaired or replaced by Supplier within ten (10) working days of receipt unless
required by Netro to meet Netro's monthly shipment commitments. In that event,
the Supplier will utilize available resources, including finished goods
inventory, overtime labor, etc. to expedite and complete the timely delivery of
Products at Supplier's expense.

8. SHIPMENT & DELIVERY.

8.1 ON-TIME DELIVERY. Supplier agrees to deliver Products on-time per its
committed delivery dates as stated on Netro's Purchase Order and agreed to by
Suppliers acknowledgment of said Purchase Order. On-time delivery is defined to
be plus or minus two (2) calendar days from the committed delivery dates.
On-time delivery point is Supplier's dock. The FOB point will be Supplier's
facility. Shipping is to be by normal transportation methods, unless otherwise
requested by Netro. Netro, in the future, may require Supplier to ship directly
to end users of the Products. These shipments will be FOB Supplier's facility.

8.2 EARLY/LATE DELIVERY. Early Delivery is defined as three (3) or more days in
advance of scheduled delivery date. Netro at its option can refuse to accept
early delivery and if Netro chooses to accept early delivery, such acceptance
must be in writing. Late delivery is defined as being three (3) or more working
days later than the scheduled and acknowledged delivery date at the applicable
dock as stated in the appropriate purchase order. If Supplier fails to make
deliveries at the specified time and such failure is caused by Supplier,
Supplier will, at no additional cost to Netro, employ accelerated measures such
as material expediting fees, premium transportation costs, or labor overtime
required to meet the specified delivery schedule or minimize the lateness of
deliveries. If despite such measures and in the event late delivery is solely
attributed to Supplier, Supplier shall, after a  grace period of ten (10)
business days, incur a liquidated damage fee for late delivery of one percent
(1%) of the Product selling price for each full week units are late after the
grace period. These liquidated damages shall be capped at seven percent (7%) of
the price of the late units. Netro may terminate the Purchase Order (or this

MANUFACTURING AGREEMENT
- --------------------------------------------------------------------------------
10. TERMINATION.

Either party shall have the right to cancel this Agreement without cause by
providing ninety (90) days written notice to the other party. Supplier will be
entitled to reimbursement for reasonable costs associated with termination
without cause by Netro or with cause by Supplier (as provided in Section 13.4),
but shall not be entitled to reimbursement if this Agreement is canceled
without cause by the Supplier or with cause (as provided in Section 13.4) by
Netro. Reasonable costs may include the contract price of all finished Products
on hand, the cost of material inventory (including handling charges and value
add) whether in raw form or work in process, the cost of material on order
(including charges) which can not be canceled, and any vendor cancellation
charges incurred with respect to material canceled or returned to the vendor.
The Supplier will use reasonable commercial efforts to mitigate these
cancellation and restocking charges through negotiation with suppliers and
utilization of materials in Supplier's other customer's products. Netro shall
have the right to any or all material received by or paid for by Netro under
this clause. In the event of a termination request by Supplier without cause,
Netro shall receive no less than ninety (90) days written notice to place a last
buy for forecasted deliveries up to (6) months inclusive of the 90 days written
notice and Supplier will provide documentation for tooling and fixtures to Netro
as requested.

11. WARRANTY.

Supplier warrants that the units of Product supplied under this Agreement will
meet the mutually agreed upon specifications in effect at the time of
manufacture and be free from defects in Supplier supplied material and
workmanship for a period of [***] from the date of manufacture. Parts not
meeting the specifications shall be returned to Supplier for replacement, repair
or credit. Supplier will return all units determined by Supplier to be warranty
defectives within ten (10) working days of receipt. The repair work will be
warranted for a period of [***] from the date of repair or for the original
warranty date, whichever is longer. Repair of out of warranty returns will be
negotiated between Netro and Supplier. Supplier will provide corrective and
preventive action for all in warranty materials identified as not meeting
specifications. Replacement, repair or credit of warranty repairs constitutes
Netro's sole remedies against Supplier for breach of warranty claims. Out-of
Warranty Products returned to Supplier for repair shall be evaluated and the
cost to repair the unit determined. Within five (5) business days of receipt of
Product Supplier will notify Netro of the estimated repair cost and will await
written authorization from Netro before starting work. Out-of-warranty repairs
will be completed and returned to Netro or end customer within fifteen (15) days
of receipt of start work authorization subject to material availability.
Products that have been subjected to abuse, misuse, accident, alteration,
neglect or unauthorized repair will be handled the same as an Out-of-warranty
repair.

THE WARRANTIES CONTAINED IN THIS SECTION ARE IN LIEU OF, AND SUPPLIER EXPRESSLY
DISCLAIMS AND NETRO WAIVES ALL OTHER REPRESENTATIONS AND WARRANTIES, EXPRESS,
IMPLIED, STATUTORY OR ARISING BY COURSE OF DEALING OR PERFORMANCE, CUSTOM,
USAGE IN THE TRADE OR OTHERWISE, INCLUDING WITHOUT LIMITATION THE IMPLIED
WARRANTIES OF MERCHANTABILITY, TITLE AND FITNESS FOR A PARTICULAR USE.

                               APPENDIX B QUALITY

(A) Supplier commits to ensure that all manufacturing, and design operations,
    including any key sub-contractor, or contract manufacturing suppliers, which
    contribute to the design, development, production, delivery and service of
    material are ISO 9000 registered by an accredited Registrar by one year
    after first purchase order is placed by Netro.

(B) Supplier commits to having a continuous improvement program in place which
    will allow it to attain and maintain "acceptable" ratings (or equivalent) on
    all quality system elements as periodically performed by Netro. An
    "acceptable" element is defined as one where the quality system meets the
    "general intent" of the quality system and is fully deployed to maintain the
    quality system and product quality. No significant deficiencies encountered
    that would jeopardize the quality system, and product quality and/or
    reliability.

(C) Supplier commits to establish key quality control (qc) verification points
    throughout the manufacturing process. These verification points should be
    located in-process as well as after MATERIAL has completed all manufacturing
    operations. The scope of these qc verification points shall be validated
    through visual or mechanical inspections and/or tests, and with the use of
    statistically valid sampling plans, that MATERIAL conforms to Supplier's
    manufacturing, product and process specifications, standards of acceptable
    workmanship, as well as other specifications which may be provided by Netro.
    Netro reserves the right to review these qc points and make suggestions for
    improvement. Supplier commits to address these suggestions through the
    implementation of appropriate corrective actions.

(D) Supplier commits to establish an end of the line Quality Assurance product
    audit on material by three (3) months after first purchase order. The focus
    of this audit shall be to replicate user application of MATERIAL as
    specified by Netro's customer. Test and examination of MATERIAL under the
    quality audit shall be at a system level, and shall include but is not
    limited to:

          a) Exercising said MATERIAL over the full spectrum of temperature
             ranges over which MATERIAL is designed to operate.

          b) Full operation of MATERIAL over a period of time not less than 72
             hours.

          c) A system for continuous monitoring of all primary product functions
             and fault detection of the MATERIAL while under this test.

    Supplier shall continuously review customer return data to ensure that the
    scope of the product quality assurance audit function includes the
    requirement(s)/condition(s) under which the return failed.

      Supplier shall perform a detailed failure mode analysis of all MATERIAL
      found defective through the quality assurance audit in line with the
      requirements and process outlined in paragraph F.

      Supplier agrees to provide to Netro on a monthly basis, results of the
      quality assurance product audit in a format specified by Netro.

(E)   Supplier commits to establishing a program of tracking monthly, quarterly,
      and annual return rates for the product manufactured under this contract.
      The Supplier agrees to update and report on returns on a quarterly basis
      to Netro.

(F)   Supplier commits to establishing a system for tracking and analysis all
      MATERIAL returned by Netro to it, as well as any MATERIAL failures which
      occur through Netro's end of the line quality assurance audit. For all
      MATERIAL in the above two categories, supplier shall perform a failure
      mode analysis, which at a minimum will be down to the component level.
      Component level failure modes will be recorded, and failed components
      found defective will be accumulated for the purpose of determining
      repetitive occurrences.

      Material shall be considered defective if it fails to meet the warranty
      specifications under this Agreement (including performance and appearance
      Specifications) or if during customer testing, installation, or use, the
      MATERIAL fails to operate as expected or specified.

      If the analysis of a return is found to be within the specifications of
      this agreement (i.e., a no trouble found condition), then Supplier shall
      track these no trouble found conditions and notify Netro of said findings
      at a minimum of a monthly interval, so that appropriate investigative
      measures may be taken to determine the root cause.

(G)   If the return rate is found to exceed a mutually agreed to acceptable rate
      or repetitive occurrences are observed with regard to component level
      failures then the supplier shall provide a written Corrective Action
      Report to Netro, explaining in detail the nature of the problem detected,
      and the step(s) Supplier proposes to correct the problem. As part of the
      plan to correct the problem, it is agreed that the Supplier shall:

            a) Incorporate the remedy in affected MATERIAL.

            b) Ship all subsequent MATERIAL incorporating the required
               modification correcting the problem at no additional charge to
               Netro; and

            c) Create a mutually agreed to plan to address the scope of
               correction and the proper course of actions to be taken by
               Supplier and Netro.



                                       2
<PAGE>   18
      Supplier and Netro shall mutually agree in writing as to the
      implementation schedule of the corrective action plan. Supplier agrees to
      use its best efforts to implement the plan in accordance with the agreed
      upon schedule. It is also agreed that the Netro shall be entitled to
      postpone at no charge to Netro, further deliveries of orders until such
      time as the remedy is implemented consistent with this Article.

(H)   As part of a program of continuous improvement, Supplier agrees to
      establish annually, improvement goals for a series of key quality
      objectives. These goals should include, but are not limited to a)
      customer return rates, b) Quality Assurance product quality audit defect
      rates, c) final system test yields. Supplier agrees to track these goals
      on a monthly basis, and to commit the resources necessary for the
      attainment of these goals.

                                   APPENDIX C

                               STATEMENT OF WORK

OBJECTIVE: Netro will help Solectron acquire high-frequency RF expertise, with
the goal of becoming proficient in manufacturing radio products within 6 to 9
months. Solectron will help Netro put processes in place that will facilitate
future product transitions, as well as prepare for volume ramp of Netro's
product line.

SCOPE OF WORK

Solectron shall make itself familiar with Netro's products, primarily by
residing on-site to learn and document processes and technology. The objective
is to fully understand the design, test and manufacturing of the Netro's product
line. Listed below are the major points that need to be addressed going forward.

1.  This phase will review the following areas:

    1.1  Netro's design, test and manufacturing process flow

    1.2  Netro's test plans and procedures, Failure diagnostics/analysis
         methodologies, cycle time, calibration procedure and cycle time, test
         cycle time, and yield data.

2.  ESS requirements (HALT, etc.)
    Solectron shall work with Netro to prepare and compile:
    2.1  Test plans
    2.2  Test Procedures
    2.3  Define failure criteria at the component, board and system level
    2.4  And provide/participate for the design inputs as a result of 2.1-2.3.

3.  ICT opportunities

STC shall work with Netro to determine which assemblies are candidates for ICT.
Netro to provide schematics for all assemblies quoted.

4.  Failure analysis/isolation/detection

    There shall be three levels of failure isolation/detection, based on
    criticality:
    4.1  Level three (board/box level failures that occur during normal
         manufacturing operations)
    4.2  Level two - component level failures which may be due to:
         4.2.1  Faulty/Bad component
         4.2.2  Design related failures (Derating factors, out of spec, etc.)
         4.2.3  Process related failures (IR reflow, shorts/opens, solder, etc.)
    4.3  Level one (Failure has been isolated to a component, cross sectioning
         may be required to determine the cause of the failure to be performed
         either at Solectron or at Solectron's supplier using Solectron's
         leverage)




                                       1
<PAGE>   22
5.   RF functional Test

Short term, Solectron will work with Netro to streamline current test process to
increase efficiency and throughput. Longer term, the focus would move towards:

     5.1  Cost/Trade off analysis on the level of automation
     5.2  Automation implementation based outcome of 5.1 above
     5.3  Increase test coverage at the box level
     5.4  Determine proper amount of time for testing

6.   Training methodology

     6.1  The Solectron project will work with Netro to understand their testing
          methodology and put forward a training plan for Solectron's operators.
     6.2  Based on the outcome in 6.1, adequate training for Solectron's
          operators/technicians/engineers will be provided.
     6.3  The Solectron project team will work to enhance the on-going RF
          training provided presently for the operators, technicians and
          engineers working at Solectron, to ensure a strong RF pool of
          resources to draw from in future.

7.   Hiring of RF engineers/technicians:

Due to increasing demand for manufacturing and testing RF products, Solectron is
in the process of recruiting additional RF/Microwave/Wireless engineers and
technicians. There are several openings within the Milpitas campus. The
Solectron Technical Center has solidly positioned its RF capabilities by
establishing several business relationships with RF consulting firms in US for
outsourcing of consulting engineering services if an when necessary. Solectron
is currently staffed for the manufacturing of PCB's from Netro, but will hire
(or transfer) resources for the radio production.

8.   Reliability

Solectron shall implement a reliability and qualification program plan in
collaboration with Netro. This plan will encompass both component and system
level testing in an attempt to help Netro with its design for reliability, yield
analysis and improvement, IQC, reduction/elimination of burn-in time, review/
audit of supplier's reliability, qualification and screening procedures,
utilization of derating factors, and worst case scenario analysis. Netro will
identify critical component list for Solectron.

9.   Source Inspection

Solectron to help perform source inspection, qualification, incoming test and
quality control for the critical RF components. Netro to identify critical
component list for Solectron.

<PAGE>   23
10.  Documentation

Solectron to assist in documenting the manufacturing process. This would include
adding more detail to current documents, rev control, visual aids, etc.

11.  Cost Reduction Efforts

Solectron feels there are opportunities for future cost reduction, illustrated
in the following examples (but not limited to):

     - Automation of current test stations
     - Design future platforms to be similar, with configuration done at the
       very end of the manufacturing process (i.e. choosing frequency range)
     - Reduction of ESS testing (by going to sampling, etc.)

right to obtain and hold in its own name all copyright registrations and other
evidence of rights that may be available for such Specifications and
Documentation. Manufacturer acknowledges Purchaser's right to place the
Specifications and Documentation in escrow in Purchaser's cost, pursuant to the
terms of Purchaser's agreements with customers and other third parties.
Notwithstanding the foregoing, in the event that Manufacturer applies an
improvement or invention to the Products which was not (a) originally conceived
of or reduced to practice in connection with a Product of Purchaser, (b) created
with the assistance of Purchaser personnel, materials or information, OR (c)
created pursuant to Section 5 hereof, such improvement or invention shall be
solely owned by Manufacturer, including without limitation, patent, copyright,

NETRO
THE WIRELESS ATM COMPANY                                          EXECUTION COPY
- --------------------------------------------------------------------------------

hereunder shall be subject to the following terms and conditions,
notwithstanding anything contained in the purchase order to the contrary.

(i) Acceptance and Rejection. Manufacturer will accept or reject purchase orders
from Purchaser in a written notice within five (5) working days of receipt
thereof, provided, however, that Manufacturer shall be required to accept any
purchase order that (A) does not increase the total amount to be purchased by
Purchaser beyond 25% of the total amount forecast during such period, and (B)
requests delivery no sooner than four (4) calendar weeks from the date of such
purchase order. Failure by Manufacturer to reject a purchase order within the
timeframe specified above shall be deemed to be acceptance of a purchase order
hereunder.

               Purchaser or its designees may elect to source inspect Products
and/or test data and results before delivery from Manufacturer. Manufacturer
will provide reasonable space for the source inspection. Manufacturer will
provide Purchaser with five (5) working days advance notice of Product
availability for source inspection and Purchaser agrees to source inspect said
Products within five (5) working days after such notification. When Purchaser
elects to perform source inspection at Manufacturer's facility, final acceptance
shall occur at the time of source inspector's written acceptance of Product. The
source inspector's written acceptance shall be made within five (5) working days
after such source inspection. If the source inspector fails to be available for
source inspection within the time frame established above, Manufacturer may ship
the Products and Purchaser will inspect the Products upon receipt as described
in the first paragraph hereof.

        (ii) Price. Following the qualification of Manufacturer for a given
Product, Manufacturer will quote a firm price for such Product, which will be
included in Appendix A to this Agreement and will be the price for a given
Product unless reduced as follows. Each such firm price quote will include a
bill of materials, cost of materials, cost of labor, profit margin and such
other detail as Purchaser shall reasonably request.

               Manufacturer will use its best efforts, with the assistance of
Purchaser, to implement an ongoing cost reduction program that will aim at a
price reduction to Purchaser of [***] percent [***] per annum, beginning once
the Manufacturer has produced more than [***] units of a Product. Manufacturer
agrees to update the Specifications and Documentation to reflect all such cost
reduction efforts and any such revised materials shall be "Specifications"
and/or "Documentation" for all purposes under this Agreement. Notwithstanding
the foregoing, no change will be made to the Specifications of or manufacturing
process for a Product without the prior written approval of Purchaser.

        (iii) Delivery. All purchase orders issued by Purchaser will be shipped
according to the schedule provided in the applicable purchase order. Deliveries
will be marked as instructed by the party placing such order, including without
limitation, with bar code labels as specified by Purchaser or its third party
contractors from time to

time, and will include all relevant test data for such shipment. All shipments
of Products are FOB Manufacturer's factory location with method of shipment and
insurance specified by and paid for by the party placing the order. If a Product
is not available for more than ten (10) working days from the originally
schedule delivery date, Manufacturer shall accrue a late fee of fifteen
one-hundredths of one percent (0.15%) of the selling price for such Product(s)
which is (are) delayed in such order for each day that such order is delayed
beyond such ten (10) working day period, up to a maximum of seven percent (7%).
Notwithstanding the foregoing, such penalties shall not apply where the delays
in shipment are as a result of design defects or Purchaser's negligence.

        (iv) Rescheduling. A purchase order may be rescheduled, prior to fifteen
(15) working days before the scheduled delivery date for such order. If a
purchase order is rescheduled for more than thirty (30) calendar days from the
originally scheduled delivery date, Purchaser shall accrue a rescheduling charge
of one percent (1%) of the selling price for such rescheduled purchase order for
each thirty (30) day period that such rescheduling of a delivery date is delayed
beyond such thirty (30) day period up to a maximum of five percent (5%). If a
rescheduling of a delivery date is delayed beyond one hundred and eighty (180)
calendar days, Manufacturer shall have the right to deliver the Products for
such purchase order on the one hundred-and-eightieth day from the originally
scheduled delivery date.

        (v) Cancellation. In the event that Purchaser cancels any purchase
order, Purchaser shall compensate Manufacturer for the reasonable, actual,
out-of-pocket expenses incurred by Manufacturer in acquiring components and
manufacturing the Products subject to such order. Manufacturer will use its best
efforts to mitigate such costs however, in the event that Purchaser is required
to compensate Manufacturer under this Section, Purchaser shall be entitled to
take title over all inventory, components and Products for which it delivers
compensation hereunder.

        (vi) Payment. Payment is due and payable fifty (50) calendar days from
the date of issuance of the invoice or shipment of the Products, whichever is
later (the "Payment Date"). Within ten (10) business days after notice by
Manufacturer of its acceptance of a purchase order, Purchaser will establish an
irrevocable letter of credit with a U.S. Bank in favor of the Manufacturer in
the amount of such purchase order (each an "LC"). Each LC shall provide that the
Manufacturer may draw upon the LC on the Payment Date, upon presentation of a
letter, certified by Manufacturer, as to the shipment of the Products and the
invoice and/or shipment date, together with such other documentation and
evidence of shipment as is reasonably established in such LC.

        (vii) Electronic Data Interchange. Manufacturer and Purchaser will
jointly implement an Electronic Data Interchange ("EDI") system that is
compliant with the EDI requirements of Purchaser's customers in a mutually
agreed to scope and timetable.

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

        (viii) Semi-Annual Review of Prices. Beginning on the date six (6)
months from the date of this Agreement, and every six (6) months thereafter, the
parties will meet to discuss in good faith revisions to the pricing and payment
terms set forth in this Section 4(b), in order to reflect competitive pressures
and other then-current market conditions.

c. Acceptance and Rejection of Deliveries. The basic acceptance criteria for
Products shall be conformance to the Specifications by Purchaser. The Purchaser,
or its third-party contractors will accept or reject deliveries of the Products
within twenty (20) working days of receipt of such Products. Such party may
elect to reject Products individually or reject lots on the basis of sample
inspections as described on Appendix A. Any Product (or lot of Products based on
a sample) which fails to meet the Specifications due to the fault of
Manufacturer, will be replaced or repaired by Manufacturer. All such Products
shall be tracked by Manufacturer's RMA system. Manufacturer shall provide
monthly reports on the status of all RMAs. If the recipient of an order does not
provide Manufacturer such notice within the twenty (20) working day period, the
Product will be presumed to have been accepted, and any defective Products will
be dealt with thereafter as warranty claims.

d. Purchases from Purchaser. Manufacturer will purchase certain components and
inventory from Purchaser on terms and conditions mutually agreeable to the
parties and pursuant to purchase orders distinct from those under this
Agreement.

5.      ENGINEERING SERVICES

a. Identification of Services. Manufacturer agrees to undertake and complete
certain manufacturing engineering tasks for Purchaser. Purchaser has described
such services to Manufacturer in detail and Manufacturer has provided purchaser
with a firm price quote for such services, both of which are attached hereto as
Appendix D. It is the parties intention that Purchaser will compensate
Manufacturer for these services proportionately to reflect the timely
achievement of milestones by Manufacturer and the value of interim milestones to
Purchaser. Therefore, within ten (10) working days after the Effective Date,
Purchaser and Manufacturer will mutually agree upon an update to Appendix D,
which will provide for the same services to be provided by Manufacturer to
Purchaser at the same price quoted by Manufacturer, but will also list key
interim milestones for such services, delivery dates for each such milestone and
payment amounts for each such milestone. As the parties identify additional
manufacturing engineering tasks with respect to existing or newly added Products
the parties will, by mutual agreement, update Appendix D in writing. The
products of the efforts of the tasks referred to on Appendix D are referred to
herein as the "Deliverables".

b. Acceptance and Rejection of Deliverables. Upon delivery of any Deliverables,
Purchaser will test, review and otherwise evaluate such Deliverables to
determine whether such Deliverables warrant modifications to the Specifications,
Documentation or manufacturing process for a Product. Within thirty (30)
calendar days of delivery of the Deliverables, Purchaser shall provide
Manufacturer with written notice of


                                      -6-
<PAGE>   8

NETRO
THE WIRELESS ATM COMPANY                                          EXECUTION COPY
- --------------------------------------------------------------------------------

acceptance or rejection of such Deliverables. In the event Purchaser rejects
such Deliverables for cause (i.e., failure to comply with the specifications for
such Deliverable), Purchaser may, at its option extend the period for delivery
of such Deliverable on the basis of the originally agreed to compensation or
terminate the project for such Deliverable with no further liability to
Manufacturer. If Purchaser rejects such Deliverable other than for cause,
Manufacturer shall nonetheless be entitled to receive the compensation as set
forth in subsection (c) below. If Purchaser accepts such Deliverable,
Manufacturer and Purchaser will work together to implement such changes as are
necessitated to the Specifications, Documentation and other materials and
Manufacturer shall be entitled to receive compensation as set forth in
subsection (c) below.

c. Ownership of Deliverables. Manufacturer understands and agrees that the work
to performed by it for Purchaser pursuant to this Agreement shall be considered
"Work Made for Hire" as that term is defined in Title 17, United States Code,
Section 201; Purchaser shall own all right, title and interest in the
Deliverables developed by Manufacturer. If, for any reason, the Works Made for
Hire rule is found not be applicable to this Agreement, Manufacturer hereby
assigns all of its right, title and interest in the Deliverables, including,
without limitation, all patent rights, copyrights, trade secrets to Purchaser.
Manufacturer agrees to cooperate with Purchaser and to execute all documents
necessary to effectuate and perfect Purchaser's ownership of and rights to the
Deliverables.

d. Compensation for Deliverables. In consideration for any engineering services
provided hereunder Purchaser will issue securities to Manufacturer (or a
wholly-owned subsidiary of Manufacturer) as follows. Upon the achievement of
each milestone for which Manufacturer is entitled to compensation pursuant to
Appendix D, Purchaser will issue to Manufacturer (or a wholly-owned subsidiary
of Manufacturer) that number of shares of the Purchaser's then most recently
issued series of Preferred Stock as is determined by dividing the dollar amount
specified for the achievement of such milestone on Appendix D by the price per
share at which shares of such series of Preferred Stock were most recently
issued. Notwithstanding the foregoing, if Purchaser effects an initial public
offering of Common Stock, then following such offering Purchaser may, at its
election, decide to compensate Manufacturer in cash, or such other mutually
agreeable form of consideration, for any services provided on or after the
effective date of such offering.

d. Termination of Projects. Purchaser may cancel a project for cause under this
Section, without any further liability to Manufacturer, if Manufacturer has not
delivered a Deliverable or other significant intermediate work product within
thirty (30) working days of the mutually agreed scheduled delivery date, or for
other material failures of Manufacturer in connection with such project.
Purchaser may also cancel a project for convenience under this Section at any
time, provided however, that if Purchaser cancels a project for convenience, and
the securities delivered by Purchaser as of such cancellation reflect, a
different percentage of the total securities originally planned to be


                                      -7-

issued for such project than the percentage of work completed by Manufacturer as
of such date, then the party to whom such benefit has accrued will provide the
other party with cash compensation or will return or grant, as appropriate,
securities to the other party, to offset such differential compensation.

e. Additional Representations. With respect to any securities issued hereunder,
Manufacturer hereby represents and warrants, and agrees to represent and warrant
at the time such securities are issued, as follows: (i) that Manufacturer has
had access to and is familiar with information concerning the Purchaser's
business, affairs, financial condition, and current prospects; (ii) that any
such securities are being acquired for its own account, not as a nominee or
agent, and not with a view to or in connection with the sale or distribution of
any part thereof; (iii) that Manufacturer understands that such securities will
not be registered under the Securities Act of 1933, and (iv) that the issuance
of such securities does not conflict with the laws of the jurisdiction in which
Manufacturer is organized. The Manufacturer further agrees that, in connection
with the initial registration of the Purchaser's securities that, upon request
of the Purchaser or the underwriters managing any underwritten initial public
offering of the Purchaser's securities, not to sell, make any short sale of,
loan, grant any option for the purchase of, or otherwise dispose of any
securities of the Purchaser (other than those included in the registration)
without the prior written consent of the Purchaser or such underwriters, as the
case may be, for such period of time (not to exceed one hundred eighty (180)
days from the effective date of such registration) as may be requested by the
Purchaser or such managing underwriters.

6.      WARRANTY

Manufacturer warrants all Products sold under this Agreement to comply with the
Specifications and be free from defects in material and workmanship under normal
and proper use for a period of [***] from the latest of the
issuance date of the invoice of the purchase order, the shipment date for such
Products and the acceptance date for such Products.

THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES EXPRESSED, IMPLIED, OR
STATUTORY, INCLUDING WARRANTY OF MERCHANTABILITY.

Within the stated warranty period, Manufacturer will repair or replace, at its
option, any Product which is returned to its plant, provided inspection and
examination discloses to Manufacturer's reasonable satisfaction that (a) the
reported defects are within the warranty coverage, (b) the Product has not been
tampered with, or (c) the Product has not been damaged due to misuse, improper
storage or maintenance, negligence or accident. Purchaser will bear the cost of
shipping such defective Products to Manufacturer, and if Manufacturer is
required to repair or replace such Products, Manufacturer will return the
warranty repaired Product shipping via the same type of service originally used
to ship the failed Product to the recipient at Manufacturer's cost.

13.     LIMITATION OF LIABILITY

Neither party nor its suppliers shall be liable for any indirect, incidental,
special, or consequential damages, including but not limited to, loss of profits
or revenue, or cost of substituted facilities, equipment or services which arise
out of performance or failure to perform any obligation contained within this
agreement, whether the claim is in contract, tort (including negligence), strict
liability or otherwise, even if such party has been advised of the possibility
of such damages.

Manufacturer or its suppliers shall not be liable for indirect, incidental,
special, or consequential damages and in no event shall the liability of the
Manufacturer arising in connection with any Products purchased under this
Agreement exceed the actual amount paid to Manufacturer for Products and
Deliverables hereunder.

14.     NON COMPETE

a. During the term of this Agreement and for [***] following the termination
hereof, so long as (i) Manufacturer's total revenue from the Products ordered by
Purchaser and its third-party contractors under this Agreement (including the
deemed value of any engineering services provided hereunder) during calendar
year 1999 is greater than or equal to the greater of (A) [***] and (B) [***] of
Purchaser's Requirement of Products during such period, (ii) Manufacturer's
total revenue from the Products ordered by Purchaser and its third-party
contractors under this Agreement (including the deemed value of any engineering
services provided hereunder) during calendar year 2000 is greater than or equal
to the greater of (A) [***] and (B) [***] of Purchaser's Requirement of Products
during such period, and (iii) Manufacturer's total revenue from the Products
ordered by Purchaser and its third-party contractors under this Agreement
(including the deemed value of any engineering services provided hereunder)
during calendar year 2001 is greater than or equal to the greater of (A) [***]
and (B) [***] of Purchaser's Requirement of Products during such period;
Manufacturer and its affiliates agree that they will not directly or indirectly
provide products or services (excluding stand-alone, receive-only Low Noise
Block down converters for broadcast television services in the consumer
marketplace which are not designed to be integrated into the broad-band
point-to-multipoint microwave radios of any third party) to any third party,
including any affiliate of Manufacturer, with the effect of aiding the design or
manufacture of non-satellite, broad-band point-to-multipoint microwave radios in
the 10 to 42 GHz frequencies to a party other than the Purchaser.
Notwithstanding the foregoing, neither the dollar volume nor the percentage
purchase requirements for the maintenance will be necessary for the maintenance
of exclusivity if (1) Manufacturer has not qualified to release the Products
listed on Appendix E hereto within the timeframes listed thereon, or (2)
Manufacturer is failing to provide Products to Purchaser in accordance with the
delivery and quality requirements set forth in this Agreement and the
Documentation.

b. For purposes of measuring the minimum dollar requirements of Section 14(a)
above, up to an aggregate of [***] worth of purchase orders and engineering
services requests placed prior to the end of a period, but which are not to be
delivered until subsequent periods may, at Purchaser's election, be included in
measuring such minimum quantities, provided that if such amounts are so included
in a period, such amounts will not be included in any subsequent periods. For
purposes of measuring the minimum percentage requirements described in Section
14(a) above, the numerator of such fraction will be the monetary value of all
cash, securities and other compensation (including for components and
engineering services) delivered to Manufacturer by Purchaser or its third party
contractors hereunder and the denominator of such fraction will be the
Purchaser's Requirement for Products. The term "Requirement for Products" shall
mean the dollar value (as measured by the price from Manufacturer to Purchaser)
of complete radios purchased by Purchaser from any source.

c. In the event that Manufacturer's quoted prices are not comparable to those
available to Purchaser from other parties on similar terms and conditions,
Manufacturer will work together with Purchaser in good faith to reach a mutually
acceptable prices.

15.     PRODUCT CHANGES

Manufacturer understands and agrees that Purchaser from time to time may make
changes to the design and/or Specifications on any Product involved with this
Agreement. Changes will be documented and provided to Manufacturer via
Engineering Change Orders ("ECOs"). Each ECO will specify an effective date for
the change. Upon receipt of an ECO, Manufacturer shall review it and provide a
written response to Purchaser within five (5) working days stating any impact to
schedule or price. Manufacturer shall not implement any ECO which delays any
delivery schedule or increases price to the Purchaser without first obtaining
written authorization from Purchaser. Upon adoption of any ECO that has a
material impact on the price for a Product, Manufacturer will requote a firm
price for such Product in accordance with the provisions of Section 4(b)(ii)
hereof. Manufacturer may also propose engineering changes to Purchaser from time
to time, which Purchaser will evaluate in good faith, and convert to ECOs if
appropriate.

In the event that Purchaser develops new or replacement products which are
suitable for manufacture by Manufacturer, the parties will work together in good
faith to add such products to Appendix A hereto and have such products
manufactured and sold hereunder.

16.     CONFIDENTIALITY

2.1     FREQUENCY PLAN

The AirStar Release 2.0 will be operated in either the 10 GHz or 26 GHz ETSI
frequency plan. The AirStar system now supports the ETSI 26 GHz band 24.5GHz to
26.5GHz with T/R spacing of 1008MHz, 7MHz of step size, supporting 7 MHz or 14
MHz channels.

The associated channel plan for the lower half of the band is listed in Table
2-1: ETSI 26 GHz Band 14 MHz Channel Plan. The table assumes that base station
uses the lower duplex frequency for transmit, although this does not need to be
the case. In some regions, the upper half of the band may be also used, which is
not illustrated here.

The ETSI 26GHz band is divided into four bands each corresponding to a unique
radio unit model:

- -   Band 1 (downstream 1): 24.5525 - 24.9935GHz

- -   Band 3 (downstream 2): 25.0005 - 25.4415GHz

- -   Band 2 (upstream 1): 25.5605 - 26.0015GHz

- -   Band 4 (upstream 2): 26.0085 - 26.4495GHz

With Release 2, the AirStar system supports the ETSI 10 GHz frequency plan in
the range 10.15GHz to 10.65GHz, with a T/R spacing of 350MHz and 3.5MHz of step
size. The system will be capable of supporting 7 MHz or 14 MHz channels. The
associated channel plans for each of the channels are listed below. The AirStar
system is configured that the lower duplex frequency is used for Base Station
transmit, higher duplex frequency is used for Base Station receive. Vice verse
for Subscriber terminals. The center frequencies are in Table 2-2: ETSI 10 GHz
Channel Plan.

                 FIGURE 2-2 - BIT ERROR RATIO (EB/NO, CIR, 4-QAM)

The values in Figure 2-2 - Bit Error Ratio (Eb/No, CIR, 4-QAM) are based on
extensive forward error correction. As stated earlier the AirStar system uses
[***], which is used in the upstream transmission. Without [***], the
[***] effect could be disastrous. The analysis below refers to the upstream
direction because it is has less

FEC overhead than the downstream direction. In the downstream t=7 thus the
error performance is slightly better.

The degradation for [***] and [***]s tolerable because these values are well
within the link rain-fade margins. One view is that these are lost margins that
affect the link availability for subscriber terminals located in an interference
zone. But this view is too pessimistic. Rain attenuation in linear unit's
increases nearly exponentially with distance. Therefor, in a rainstorm the
interference source is attenuated much more than the local source and no
significant margin is lost.

At [***] the degradation is beyond acceptable performance. Therefore, a
suitable frequency reuse scheme will exclude coverage for areas with CIR
below [***].

2.1.3    Frequency Reuse Assumptions

1.   The base stations use directional (sectorial) antennas with front-to-back
     of at least 20 dB, antenna pattern per ETSI specs (worst case).

2.   The subscriber terminals use directional antennas with front-to-back ratio
     of at least 20 dB.

3.   Each sector transmits in one frequency. If two or more channels are
     aggregated in one sector, they are considered one frequency band for this
     analysis. Specifically, if four 7 MHz channels are in use, a two-frequency
     reuse scheme allows to group channels (1,2) as frequency f1 and channels
     (3,4) as f2.

4.   Cross polarization is not included. This degree of freedom is additional
     to this analysis and can be added to double the capacity, however
     horizontal polarization will have a shorter range then vertical
     polarization caused by rain attenuation.

5.   The transmission is full duplex, Frequency division duplex (FDD). All base
     stations transmit in the same frequency band.

6.   4-QAM modulation with strong FEC, such as BCH, [***] block.

7.   All terminals have line of sight to their base station.

8.   The areas is a perfect plane where all base stations are visible (a worst
     case for interference).

9.   Any receiver can reject adjacent channels to a negligible interference. A
     [***] dB rejection is sufficient for most situations discussed below.

10.  Free space attenuation law (inverse Square of distance).


2.1.4    Two-Frequency Arrangement

A two-frequency arrangement can be assembled by a square cell shape or by
hexagonal shape. An example of a square arrangement is shown in Figure 2-3 -
Two-frequency square-cell reuse scheme.

2.1.5   TWO-FREQUENCY ARRANGEMENT COVERAGE

Based on the assumptions above and the AirStar system elements analysis of
coverage of a two-frequency square pattern has shown that about [***]% of
subscribers can have good CIR with the 125 mm subscriber antenna. A large, 390mm
antenna increases CIR-limited coverage to virtually [***]%. This performance is
due to the following key enabling features.

- -       Interference-tolerant 4-QAM modulation

- -       Directional subscriber terminal antennas

- -       Sector antennas width with fast roll-off

- -       A special square-zone reuse geometry

- -       Extensive Forward Error Correction

3 SYSTEM COMPONENTS

3.1 Base Radio Unite (BRU)

The BRU is an outdoor unit, which includes radio frequency (RF) transmitter and
receiver, as well as a sectorized integral antenna. It utilizes a frequency
diplexing technique which allows transmit and receive to share the same
antenna. The main function of a BRU is to interface with the BMU/BMM and
perform RF up and down conversion from and to an intermediate frequency (IF).
The integral antenna is field replaceable under certain technical instructions.

Figure 3-1 illustrates a simplified system block diagram of the BRU. The
diagram aims to identify the key modules within the BRU.

The BRU and BMM IF interfaces are [***] Ohm TNC connectors. The BRU has an AGC
circuit on the IF interface to normalize the IF signals and overcome cable loss
due to varying lengths. Based on the cable AGC dynamic range, the IF cable type
can be employed based on the length requirement, for example LMR240 for less
than [***] meter and LMR400 for less than [***] meters.

Use only coaxial cable that meets the specifications in the Table below.

3.2     SUBSCRIBER RADIO UNIT (SRU)

The SRU is a compact outdoor unit, which includes radio frequency (RF)
transmitter and receiver, as well as an integral antenna. For certain
applications an optional non-integral antennae can be used to increase the link
performance. The SRU utilizes a frequency diplexer, which allows transmitter and
receiver to share the same antenna unit.

The main function of an SRU is to provide a link to the BRU and to interface
with SAS at an intermediate frequency (IF).

3.2.2   RADIO UNIT PERFORMANCE CHARACTERISTICS

The same radio unit is used in the SRU as in the BRU with different packaging.
The subscriber radio units conform to the same generic radio unit specifications
summarized in Table 3-10. The ETSI 26 GHz SRU conforms to the same
specifications in Table 3-11. The ETSI 10 GHz SRU conforms to the same
specifications in Table 3-12.

3.2.3   TRANSMIT POWER CONTROL

The subscriber radio unit transmit power is controlled in a closed loop manner
via feedback from the BSC to the SAS in the CellMAC overhead, so that all
subscriber transmissions arrive at the base station at the same power level
regardless of range or rain fade conditions. The SRU transmit power shall be
dynamically controlled over the specified range in [***] dB increments with an
accuracy of [***] dB via CellMAC.

3.2.4   MOUNT

The mount is different for the antenna options as described below.

3.2.4.1 WIND LOADING

The SRU and mounts are designed to operate under wind gusts or sustained loads
of up to 145 km/hr, and survive up to 200 km/hr.

3.2.4.2 INTEGRAL ANTENNA MOUNT

The mechanical interface for the 26 GHz is a two-bolt attachment to the SRU
support cradle. The SRU cradle mounts to the outside wall or other mounting
surface at the subscriber premises.

SYSTEM FUNCTIONAL SPECIFICATION FOR AIRSTAR                               NETRO
- --------------------------------------------------------------------------------

For the 10GHz system the mechanical interface is a one bolt attachment to the
SRU support cradle. The SRU cradle mounts to the outside wall or other mounting
surface at the subscriber premises. The mounting is intended to be low cost and
simple to install in common with a high volume subscriber application. Panning
in both azimuth and elevation is catered for, with a simple locking mechanism.

3.2.4.3 NON-INTEGRAL 26 GHZ ANTENNA MOUNT

The antenna is connected to a pole mount and the SRU is connected to the
antenna. This allows the radio transceiver to be removed without the need to
realign the antenna. The mounting system uses a waveguide flange and quick
release mounts, as is standard in the point to point area.

3.2.5   IF INTERFACE

The SAS-SRU IF interface is identical to the BRU-BMM IF interface.

3.2     SUBSCRIBER RADIO UNIT (SRU)

The Subscriber Radio Unit (SRU) shown on the following page is designed to fit
in a variety of customer premise environments. It is built with an integral
directional antenna and weighs less than 6 kg. The standard subscriber antenna
is a 125mm lens-corrected horn. This provides a gain of 28dBi minimum in 24GHz,
26GHz band, 32dBi minimum in 38 GHz band. The radiation pattern subscriber radio
unit exceeds the requirements for ETSI point to multi-point equipment. If higher
gain is required, the non-integral version of the antennas can be used. These
provide a gain up to 40dBi minimum.

In general, the 39 GHz band is divided into four bands:

               -  Band 1:38.60-38.95 GHz

               -  Band 3: 38.95-39.30 GHz

      to be ISO 9000 registered and commits to ensure that all sub-contractors
      or contract manufacturing manufacturers, which contribute to the design,
      development, production, delivery and service of material will become ISO
      9000 registered by an accredited Registrar within eighteen (18) months
      after first purchase order is placed by Purchaser.

(B)   Manufacturer commits to having a continuous improvement program in place
      which will allow it to attain and maintain "acceptable" ratings (or
      equivalent) on all quality system elements as periodically performed by
      Purchaser. An "acceptable" element is defined as one where the quality
      system meets the "general intent" of the quality system and is fully
      deployed to maintain the quality system and product quality. No
      significant deficiencies encountered that would jeopardize the quality
      system, and product quality and/or reliability.

(C)   Manufacturer commits to establish key quality control ("QC") verification
      points throughout the manufacturing process. These verification points
      should be located in-process as well as after material has completed all
      manufacturing operations. The scope of these QC verification points shall
      be validated through visual or mechanical inspections and/or tests, and
      with the use of statistically valid sampling plans, that material conforms
      to Manufacturer's manufacturing, product and process specifications,
      standards of acceptable workmanship, as well as other specification's
      which may be provided by Purchaser. Purchaser reserves the right to review
      these QC points and make suggestions for improvement. Manufacturer commits
      to address these suggestions through the implementation of appropriate
      corrective actions.

(D)   Manufacturer commits to establish an end of the line Quality Assurance
      product audit on material by three (3) months after first purchase order.

39 GHz Point to Multipoint Radio Subsystem Specification


      Manufacturer shall perform a detailed failure mode analysis of all
      material found defective through the quality assurance audit in line with
      the requirements and process outlined in paragraph F.

      Manufacturer agrees to provide to Purchaser on a monthly basis, results of
      the quality assurance product audit in a format specified by Purchaser.

(E)   Manufacturer commits to establishing a program of tracking monthly,
      quarterly, and annual return rates for the product manufactured under this
      contract. The Manufacturer agrees to update and report on returns on a
      quarterly basis to Purchaser.

(F)   Manufacturer commits to establishing a system for tracking and analysis
      all material returned by Purchaser to it, as well as any material failures
      which occur through Purchaser's end of the line quality assurance audit.
      For all material in the above two categories, Manufacturer shall perform a
      failure mode analysis, which at a minimum will be down to the component
      level. Component level failure modes will be recorded, and failed
      components found defective will be accumulated for the purpose of
      determining repetitive occurrences.

      Material shall be considered defective if it fails to meet the warranty
      specifications under this Agreement (including performance and appearance
      Specifications) or if during customer testing, installation, or use, the
      material fails to operate as expected or specified.

      If the analysis of a return is found to be within the specifications of
      this agreement (i.e., a no trouble found condition), then Manufacturer
      shall track these no trouble found conditions and notify Purchaser of said
      findings at a minimum of a monthly interval, so that appropriate
      investigative measures may be taken to determine the root cause.

(G)   If the return rate is found to exceed a mutually agreed to acceptable rate
      or repetitive occurrences are observed with regard to component level
      failures then the Manufacturer shall provide a written Corrective Action
      Report to Purchaser, explaining in detail the nature of the problem
      detected, and the step(s) Manufacturer proposes to correct the problem. As
      part of the plan to correct the problem, it is agreed that the
      Manufacturer shall:

      a)   Incorporate the remedy in affected material.



                                      A-4
<PAGE>   79

      b)   Ship all subsequent material incorporating the required modification
           correcting the problem at no additional charge to Purchaser; and

      c)   Create a mutually agreed to plan to address the scope of correction
           and the proper course of actions to be taken by Manufacturer and
           Purchaser.

      Manufacturer and Purchaser shall mutually agree in writing as to the
      implementation schedule of the corrective action plan. Manufacturer agrees
      to use its best efforts to implement the plan in accordance with the
      agreed upon schedule. It is also agreed that

39 GHz Point to Multipoint Radio Subsystem Specification


      Purchaser shall be entitled to postpone at no charge to Purchaser, further
      deliveries of orders until such time as the remedy is implemented
      consistent with this Article.

(H)   As part of a program of continuous improvement, Manufacturer agrees to
      establish annually, improvement goals for a series of key quality
      objectives. These goals should include, but are not limited to a) customer
      return rates b) Quality Assurance product quality audit defect rates, c)
      final system test yields. Manufacturer agrees to track these goals on a
      monthly basis, and to commit the resources necessary for the attainment of
      these goals.

NOTES:

Completion of the project definition means a resource plan is completed and
agreed upon in writing by both parties.

The units are to be tested against a mutually agreed written test plan. This
test plan to be prepared and finalized ahead of the delivery of the units to
prevent the qualification from being gated by this activity.

The units described as "pilot" are the units which are candidates to become the
"beta" deliverables from Netro under its gate process. They are intended to be a
"production" quality but to be built from early product documentation. These
designs are intended to migrate to "limited availability" and then "general
availability" without significant redesign.

The last milestone for each frequency marks the point at which the

                                  OEM AGREEMENT

                                (Cisco as Seller)

This OEM Agreement (the "Agreement") is made as of the 7th of December, 1998
(the "Effective Date") by and between Cisco Systems, Inc., a California
corporation, having principal offices at 170 West Tasman Drive, San Jose,
California 95134-1706 ("Cisco") and Netro Corporation, a California corporation
having its principal place of business at 3860 North First Street, San Jose,
California 95134 ("Netro").

                                    RECITALS

      A. Netro has been purchasing from Cisco the Cisco MGX 8220 shelves and
associated products, software and firmware by means of purchase orders over the
past several months. These shelves have been, in turn, integrated with Netro's
Base Station Controller boards and resold to third parties as a part of the
"AirStar" wireless communications systems developed by Netro.

      B. Netro is developing an independent solution, which will permit it to
sell its systems without relying on the Cisco MGX 8220 shelves; however, Netro
requires on-going access to the Cisco MGX 8220 shelves for resale during this
development period. Cisco desires to sell the Cisco MGX 8220 shelves and
associated products, software and firmware to Netro during the development
period to enable Netro to transition to an independent solution.

      C. Netro also desires access to certain Cisco technology and intellectual
property in order to transition to an independent solution. Cisco desires to
license such technology to Netro under a separate license agreement that will be
executed contemporaneously with this Agreement (the "Technology Agreement").

      D. The parties now desire to enter into an agreement pursuant to which
Cisco agrees to sell and Netro agrees to purchase a limited number of the
Products under the terms and conditions set forth herein.

      NOW, therefore, in consideration of the terms and conditions of this
Agreement, the parties agree as follows:

<PAGE>   3
      (d) Netro must brand, promote, market and sell the Products as Netro's own
products using Netro's own trademarks, trade names and trade dress.
Additionally, Netro is responsible for re-labeling the Products, by removing
Cisco labels or completely covering Cisco labels, so that only Netro's name
appears on the Product. Netro may not partially remove, cover or deface Cisco's
label in a manner that may cause damage to Cisco's trademark rights. Therefore,
Netro agrees that upon request Netro will permit Cisco to inspect samples of the
relabeled Products and Netro will correct any improper labeling identified by
Cisco.

      (e) Netro must load the Software onto each unit of the Products.

      Netro acknowledges that failure to comply with Section 2.1(d) or Section
2.1(e) shall constitute a breach of the Agreement and shall entitle Cisco to

indemnify, defend and hold Cisco harmless from and against any claim, liability
or damages which may result from reproducing, using or distributing any third
party software contained in the Software in a manner not expressly authorized
under this Agreement (e.g., Netro distributes the Software on a stand alone
basis or Netro distributes more than [***] copies of the Software).

      (c) Netro may not purchase more than [***] of the Products (in terms of
completed systems as more fully described in Appendix A).

      (d) Netro may not purchase the Products after the end of the Purchase

      2.3 Software License. Cisco hereby grants Netro a non-exclusive license to
use the Software solely in conjunction with, and as incorporated on, such
Products, subject to payment of license fees as included in the purchase price
for each Product. Netro may sublicense such rights to use the Software only to
its customers, subdistributors (subject to the condition as set forth in Section
2.2(b) and their customers (and any customers' lessees) who purchase the
Products provided that any such customer must execute an end user agreement
meeting the requirements of Section 2.4. Netro receives no title or ownership
rights to the Software. Except for the license granted in this Section 2.3, all
right, title and interest in the Software shall remain

[***] CONFIDENTIAL TREATMENT REQUESTED


                                      -3-
<PAGE>   4
the exclusive property of Cisco or its licensors. Except as may otherwise
expressly be set forth in this Agreement, this Agreement does not entitle Netro
to the receipt or use of, or access to, Software source code or any right to
reproduce the Software or the documentation. None of Netro or any of its
sublicensees shall decompile, reverse engineer or otherwise attempt to gain
access to the Software source code.

      2.4 End-User License. Distribution of Software shall be subject to Netro's
end user customers being bound by an end user license agreement which at the
least shall (i) grant each such customer a nontransferable, non-exclusive, fully
paid license to use the Software solely in conjunction with, and as incorporated
on, the Products obtained from the Netro and solely for such customer's internal
business purposes; (ii) indicate that Cisco and its licensors are the owners of
the Software; (iii) prohibit the customer from decompiling, reverse engineering
or otherwise attempting to gain access to the Software source code; (iv)
identify Cisco as a third-party beneficiary of the End User Agreement; and (v)
indicate that Cisco accepts the rights of a third party beneficiary. Netro shall
prepare a translation of such End User Agreement to be used for informational
purposes only; the English version of the End User Agreement shall control at
all times. Netro will provide Cisco with copies of End User Agreements executed
by customers, upon request. Netro will use its best efforts to ensure that all
customers abide by the terms of their End User Agreements. Upon request by
Cisco, Netro will keep Cisco apprised of its activities to enforce such
provisions with particular customers. Netro shall ensure that Cisco will have
the right to enforce such agreements as a third-party beneficiary. Netro agrees
that (i) Cisco may join Netro as a named plaintiff in any suit brought by Cisco
against customers and (ii) Netro will take such other actions, give such
information and render such aid, as may be necessary to allow Cisco to bring and
prosecute such suits.

3.    PURCHASE PRICE AND DISCOUNT

      3.1 Price. The purchase price to Netro for the Products pursuant to this
Agreement shall be [***] percent off Cisco's then-current list price, a copy of
which is attached hereto as Appendix A. Appendix A shall be revised or replaced
if Cisco's list prices change.

4.    PURCHASE ORDERS

      4.1 Ordering Period. Netro shall purchase the Products pursuant to this
Agreement by issuance of its Purchase Orders within the Purchase Period. This
Agreement shall control the purchase of all Products by Netro from Cisco, and no
terms in any Purchase Order, invoice, acknowledgment or like document shall
serve to add to or modify the terms of such sales unless agreed to in a writing
signed by both parties

      4.2 Purchase Order and Acceptance. Purchase Orders may be made by
telephone and, in such event, shall be followed by a hard copy (including
facsimile) confirming the Purchase Order within five (5) days. Cisco shall
promptly acknowledge Purchase Orders submitted by Netro and, if such Purchase
Orders conform to the terms and conditions of this Agreement and Netro is in
compliance with the terms and conditions of this Agreement, then Cisco will
accept the Purchase Order. Purchase Orders shall specify a lead time not less
than Cisco's then current


[***] CONFIDENTIAL TREATMENT REQUESTED


                                      -4-
<PAGE>   5
standard lead time, which shall be thirty (30) days unless Cisco notifies Netro
to the contrary. Cisco shall use reasonable efforts to notify Netro of the
acceptance or rejection of a purchase order within ten (10) days of receipt of
the purchase order, however, no purchase order will be binding upon Cisco until
accepted by Cisco in writing. Partial shipment of an order will not constitute
acceptance of an entire order. Cisco shall use reasonable efforts to ship
Products covered by a Purchase Order so as to ensure receipt prior to the
corresponding confirmed delivery date. Netro's sole and exclusive remedy if
Cisco fails to so ship such Products at that time shall be to require Cisco to
reschedule delivery within fourteen (14) days of the original scheduled delivery
date.

      4.3 Forecasts. Not less than five (5) days after the Effective Date, Netro
shall deliver to Cisco its good faith, non-binding forecast of Netro's estimated
demand for the during the first two (2) calendar quarter of the Purchase Period.
Netro shall deliver to Cisco a good faith, non-binding forecast for each
additional calendar quarter at least sixty (60) days prior to the commencement
of such calendar quarter. The submission of a forecast shall not require Netro
to make any purchases and does not constitute an order.

      4.4 Cancellation. Netro may cancel, postpone or reschedule delivery of the
Products ordered pursuant to Purchase Orders upon notice to Cisco prior to
scheduled delivery as set forth below. Any cancellation of delivery of the
Products less than ninety (90) days prior to the scheduled delivery date shall
be subject to a cancellation charge to Netro based on the table below. A
postponement or postponements which are to a date more than thirty (30) days
after the original scheduled delivery date and which are made at Netro's request
may at Cisco's option by written notice to Netro be treated as a cancellation
pursuant to this Section 4.4. The provisions of this Section 4.4 shall survive
any termination of this Agreement with respect to Purchase Orders issued prior
to such termination.

13.   TERM

      13.1 Term. This Agreement shall commence as of the Effective Date and

accordance with this Section 13. Termination shall not excuse either party from
payment of amounts owed to the other party prior to termination.

      13.2 Termination for Breach. Either party may terminate this Agreement
and/or cancel any or all Purchase Orders for undelivered Products upon written
notice to the other party if such other party fails to correct any failure to
fulfill any of its obligations under this Agreement, within thirty (30) days
after receipt of notice specifying such failure, except in the case of breaches
of the payment obligation, where termination shall be effective fifteen (15)
days from the date of notice if the default is not cured. Termination shall not

more of the voting stock of Netro is acquired, directly or indirectly, by a
third party, (b) if a third party is able to appoint or cause to be appointed a
majority of the members of the board or directors of Netro, or otherwise control

15.   INTELLECTUAL PROPERTY INDEMNIFICATION.

      15.1 Cisco's Obligation.

      (a) Indemnity. Cisco agrees to defend and hold Netro harmless against any
loss, liability or expense (including reasonable attorneys fees) paid to third
parties arising from any action or claim brought or threatened against Netro
alleging that the Products under normal use infringe any third party's patent,
copyright, trademark, trade secret or other intellectual property right. Cisco
will be released from its obligations under this Section 15.1 unless Netro
provides Cisco with (i) prompt written notice of such claim or action, (ii) sole
control and authority over the defense or settlement of such claim or action and
(iii) proper and full information and reasonable assistance to defend and/or
settle any such claim or action.

      (b) Remedy. In the event that the Products are held, or in Cisco's sole
opinion, may be held to constitute such an infringement, Cisco may, at its
option and expense, (i) obtain for Netro the right to continue to use such
Products as intended or (ii) modify the Products so that they become
non-infringing. If neither of the foregoing alternatives is in Cisco's sole
opinion reasonably available to Cisco, Cisco shall accept return of the
infringing Products and refund to Netro the depreciated value of the Products,
as measured over a thirty-six (36) month life span.


                                      -12-
<PAGE>   13

      (c) Limitations. Notwithstanding the provisions of Section 14 above, Cisco
assumes no liability for infringement claims arising from (i) combination of the
Products with other products not provided by Cisco, where the Products alone
would not infringe, (ii) the modification of the Products unless such
modification was made or authorized by Cisco, where such infringement would not
have occurred but for such modifications, (iii) integration of Netro's Boards
and the Product, where such infringement would not have occurred but for such
integration, (iv) Cisco's compliance with specifications provided by Netro, (v)
any marking or branding placed on the Products by, or at the request of, Netro,
or (vi) any third-party products furnished hereunder to complete Netro's order
which are not ordinarily supplied by Cisco. Further, Netro agrees to defend and
hold Cisco harmless against any loss, liability or expense (including reasonable
attorneys' fees) paid to third parties arising from any action or claim brought
or threatened against Cisco and based on or as a result of any or items (i)
through (vi) above.

      (d) DISCLAIMER. THE FOREGOING STATES THE ENTIRE LIABILITY AND OBLIGATIONS

to register any trademarks, marks or trade names confusingly similar to the
trademarks.

releases and forever discharges Cisco and its direct or indirect assigns,
parents, predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants, successors and
assigns, past and present, and each of them, from any and all claims, liens,
demands, causes of action, obligations,


                                      -15-
<PAGE>   16
damages and liabilities, known or unknown, that Netro has had in the past, or
now has, or may have in the future against Cisco, or any other persons or
entities, arising directly or indirectly out of or related in any way to any
prior business dealings, negotiations, discussions or agreements between parties
or their predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants successors and

or in the future have under the provisions of California Civil Code Section
1542, which section has been explained fully by counsel and which provides as
follows:

suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with debtor.

      (c) Cisco's Release. Cisco hereby releases and forever discharges Netro
and its direct or indirect assigns, parents, predecessors, successors,
subsidiaries or affiliated corporations or business entities, past and present,
as well as its directors, officers, partners, shareholders, agents, employees,
attorneys, servants successors and assigns, past and present, and each of them,
from any and all claims, liens, demands, causes of action, obligations, damages
and liabilities, known or unknown, that Cisco has had in the past, or now has,
or may have in the future against Netro, or any other persons or entities,
arising directly or indirectly out of or related in any way to any prior
business dealings, negotiations, discussions or agreements between parties or
their predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants successors and
assigns, past and present. Cisco agrees and covenants that it will not ever
institute any suit or action at law or in equity against Netro by reason of any
claims or causes of action described above.

      (d) Cisco's Waiver of Unknown Claims. Cisco expressly understands and
acknowledges that it is possible that unknown losses or claims exist or that
present losses may have been underestimated in amount or severity, and that it
explicitly took that into consideration in entering into this Agreement. With
knowledge of the possibility of unknown claims, a portion of the consideration
provided for herein was given in exchange for a full accord, satisfaction and
discharge of all such claims. Consequently, Cisco acknowledges and agrees that
it is fully aware of and hereby waives all rights or benefits which it may now
or in the future have under the


                                      -16-
<PAGE>   17
provisions of California Civil Code Section 1542, which section has been
explained fully by counsel and which provides as follows:

A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with debtor.

      (e) Limitation. The parties acknowledge and agree that the mutual releases
and waivers contained in Sections 17.13(a), (b), (c) and (d) above do not apply
to claims, liens, demands, causes of action, obligations, damages and
liabilities arising out of, or relating to, (1) any purchase orders for the
Products placed Netro and accepted by Cisco prior to the Effective Date of this
Agreement or (2) a breach of the terms and conditions of this Agreement or the
Technology Agreement.

including any Appendices, schedules and tables attached hereto which either have
been specifically referred to herein or have been initialed by the parties,

matter. This Agreement supersedes all prior discussions, understandings,
agreements and representations with respect to the subject matter hereof.

under this Agreement and no other relationship is intended, including a
partnership, franchise, joint venture, agency, employer/employee, fiduciary,
master/servant relationship, or other special relationship. Neither party shall
act in a manner which expresses or implies a relationship other than that of
independent contractor, nor bind the other party. The parties acknowledge and
agree that any breach of the foregoing sentence shall be deemed a material
breach of this Agreement.

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the day

1.3   SOFTWARE

Cisco will modify its basic MGX 8220 software for Netro. The Netro version will
support connection to BPX through the standard UNI format mode and will have
substantially the same functionality and performance as the basic MGX 8220
software, except for the following changes and feature restrictions:

(1) This new release of software for Netro will be called "NETRO.019" or
NETRO.Oxxx

(2) The existing AXIS default prompt would be changed to NETRO and would look
like "NETRO.ShelfName.Shelf #.ShelfStatus" where ShelfStatus of "a" means active
and "s" means standby.

(3) The standard prompt would look like "ShelfName.Shelf #.ShelfStatus"

(4) NETRO.Oxxx s/w release would only support 2-ASCs and a choice of 2-BNM-T3 or
2BNM-E3 or 2BNM-155.

(5) NETRO.Oxxx s/w release would not recognize and support SRM-T1E1 or SRM-3T3.

(6) NETRO.Oxxx s/w release would only recognize and support Netro BSC-SMs
(BSCM-2 and BSCM-4) in a bounded Axis shelf. Any other type of AxisSM would be
supported.

(7) NETRO.Oxxx would not include any Cisco-Internet Protocol contents.

(8) NETRO.Oxxx would not support SV+(StrataVierrt).

(9) NETRO.Oxxx uplink interface will only support UNI format.

(10) NETRO.Oxxx s/w release would not provide any support for LMI (Local
Management Interface), policing or congestion management.

(11) NETRO.Oxxx s/w would not provide any multiservice capabilities, for
example, services and protocols specific to handling non-ATM traffic, packet
voice/fax/video, compression, VOIP, SGCP/H.xxx signaling, SS7 protocol handling
etc.

otherwise transferred by either without the prior written consent of the other.
This Agreement shall bind and inure to the benefit of the successors and
permitted assigns of the parties.

        13.3 Notices. All notices required or permitted under this Agreement
