          Customer by a court of law, arbitration or other adjudication of the
          claim.

          procure the right for Customer to continue using such Products or
          Software or to replace or modify same so that they become non-
          infringing as long as they continue to conform in all material
          respects to the Product specifications, and, if neither of the
          foregoing alternatives is available on terms that are acceptable to
          Seller, Customer shall at the written request of Seller, return the
          infringing or potentially infringing Products or Software and all the
          rights thereto at Seller's expense. Customer shall receive a refund of
          the prorated undepreciated portion of the Purchase Price actually paid
          by Customer to Seller for the returned portion of the Products. The
          Purchase Price shall be depreciated over a five (5) year period.

     c.   Seller shall have no obligation to Customer with respect to any claim
          of patent or copyright infringement which is based upon (i) adherence
          to specifications, designs or instructions furnished by Customer; (ii)
          the combination, operation or use of any Products supplied hereunder
          with products, software or data with which the Products are not
          intended to be used or for which the Products are not designed; (iii)
          the alteration of the Products or modification of any Software made by
          any party other than Seller; or (iv) the Customer's use of a
          superseded or altered release of some or all of the Software if
          infringement would have been avoided by the use of a subsequent
          unaltered release of the Software that is provided to the Customer.

Introduction

This exhibit establishes the Performance Criteria and Procedure to be used for
the Engineering and Optimization for the Products ("Product" shall mean Seller's
SpotLight 2000 product). The Engineering and Optimization Procedure consists of
[***].  The Engineering and Optimization Procedure consists of separate
activities for analog and CDMA consisting of:

[***]

Comp1etion of the Engineering and Optimization of a SpotLight shall be indicated
by [***] found at the end of this Exhibit E.

[***]

In order for Customer and Seller to configure the Product, Customer must provide
the following specific cell site information for all current and planned sites
in the area of Customer's network where Product is to be installed. The
information is required for all sites regardless of whether the SpotLight
Product is to be installed in that particular site, unless specifically
designated as "Required for Product sites only" in the list below, which
indicates that the information is required only for sites where Product is to be
installed.

The collection and measurement process described in this section will be
followed during both the Baseline Performance Collection and the Performance
Collection and Evaluation.  Drive test route(s), drive test equipment, data to
be collected during drive tests, number of runs per drive test route and
frequency of data sampling all must be agreed to by Customer and Seller prior to
beginning the Measurement Process.

Information discovered in the drive tests and information that must be provided
by customer and included in both the Baseline Performance Collection and the
Performance Collection and Evaluation include but are not limited to:

[***]

In addition to collecting the above information, switch statistics from the
previous year must be analyzed to determine if adjustments due to seasonal
variation between the baseline data collection phase and the Product data
collection phase need to be made.  Customer must provide either the actual
switch statistics or summaries of seasonal statistical traffic trends.

Customer must provide a log of all system changes during both the Baseline
Performance Collection phase and the Performance Collection and Evaluation
phase, recording the occurrences of such events as cell site additions,
frequency re-tunes, outages, etc.  Customer must collect the switch statistics
and provide them to Metawave on a daily basis.

The calculation for Lost Calls Percentage and Ineffective Attempts Percentage
will be calculated using the following equations unless otherwise agreed to by
Seller and Customer:

Using the procedure set forth in the Measurement Process section of this
exhibit, Customer and Seller will perform drive tests to determine the current
performance characteristics of the existing CDMA and analog networks.  Customer
and Seller must agree in writing as to the validity of baseline switch statistic
data and drive test data.

The duration of the baseline sampling time period shall be mutually agreed upon.
[***].  Switch statistics collected during the baseline sampling time period
will include both daily summaries (excluding maintenance windows) and system
busy hour summaries.
