of this Agreement or other documents entered into or executed in connection with
this Agreement.

3.7  Construction and Interpretation

a.The language of this Agreement shall in all cases be construed simply, as a
whole and in accordance with its fair meaning and not strictly for or against
any party. The parties agree that this Agreement has been prepared jointly and
has been the subject of arm's length and careful negotiation. Each party has
been given the opportunity to independently review this Agreement with legal
counsel and other consultants, and each party has the requisite experience and
sophistication to understand, interpret, and agree to the particular language of

c.Whenever any party is entitled to interest under this Agreement, the amount of
interest shall be determined using 12% per annum, or the highest amount allowed

3.8  Cumulative Remedies

Except as specifically identified as a party's sole remedy, any rights of
Cancellation, Termination, liquidated damages, or other remedies prescribed in
this Agreement are cumulative and are not exclusive of any other remedies to
which the injured party may be entitled. Neither party shall retain the benefit
of inconsistent remedies.

3.9  Delivery, Performance, and Acceptance

SUPPLIER acknowledges the competitive telecommunications marketplace in which
CINGULAR operates and understands CINGULAR's business requires prompt Delivery
of Material and provision of Services by the specified Delivery Dates.
Therefore, the parties agree that all dates for Delivery of Materials and
Services are firm, time is of the essence, and SUPPLIER will complete such
Delivery in strict conformance with the Specifications.

For Orders that involve Field Trials, CINGULAR's Acceptance Test Period shall
commence upon (i) CINGULAR's receipt of SUPPLIER's Notice of Completion, or
(ii) upon CINGULAR's receipt of Material where SUPPLIER provides no Services
other than shipping. If Materials or Services are not in strict compliance with
the Specifications, CINGULAR shall so notify SUPPLIER and provide SUPPLIER an
opportunity to cause such Material or Service to strictly comply with the Specs.
After any corrective action, SUPPLIER shall provide a Notice of Completion and
CINGULAR shall have the right to start a new Acceptance Test Period. If the
Materials or Services successfully completes the Acceptance Tests during the
Acceptance Test Period, CINGULAR shall indicate its Acceptance by signing the
Acceptance Letter and delivering a copy thereof to SUPPLIER. Notwithstanding
CINGULAR's Acceptance, CINGULAR retains the right to revoke Acceptance under and
in accordance with Uniform Commercial Code Section 2-608. In no event shall
CINGULAR's use of Material or Service during the Acceptance Test Period
constitute Acceptance, nor will Acceptance be deemed to occur prior to the date
SUPPLIER completes its Delivery.

When CINGULAR's order for Materials to be furnished by SUPPLIER under this
Agreement does not require installation of the Materials, Cingular will have
thirty calendar days in which to notify SUPPLIER in writing if such Materials
are found not to be in material compliance with applicable Specifications. Where
materials are found and notified to SUPPLIER, SUPPLIER, at SUPPLIER's expense,
shall ship within five (5) calendar days from receipt of CINGULAR's notification
the replacement Goods or parts in order to correct such defect(s). SUPPLIER
shall provide CINGULAR a telephone number to call in order to make such
notification. CINGULAR shall then have a new period of fifteen (15) days in
which to notify SUPPLIER if such Materials are found not to be in materials
compliance with applicable Specifications. Such Materials shall be deemed
accepted by CINGULAR at the end of such period, unless SUPPLIER receives such
notification.

When CINGULAR's Order to Materials to be furnished by SUPPLIER under this
Agreement does require Installation of the Materials, at reasonable times during
the course of Installation by SUPPLIER, CINGULAR may, or upon the request of
SUPPLIER, at reasonable intervals during the course of Installation, CINGULAR
shall, inspect completed portions on such Installation. Upon SUPPLIER's further
request, and upon sufficient notice to CINGULAR, CINGULAR shall observe
SUPPLIER's testing of the Materials being installed to determine SUPPLIER's
material compliance with applicable Installation Specifications and procedures.
The Installation shall be considered complete and ready for acceptance by
CINGULAR when the Materials have been installed, wired, adjusted and tested by
SUPPLIER in material compliance with applicable Installation Specifications and
procedures. Upon completion of the Installation, SUPPLIER will submit to
CINGULAR in writing a "Notice of

[***] Confidential treatment requested pursuant to a request for confidential
treatment filed with the Securities and Exchange Commission. Omitted portions
have been filed separately with the Commission.

Completion." CINGULAR shall then be entitled to perform its own acceptance test
to determine SUPPLIER's material compliance with applicable Specifications,
and/or in accordance with any procedures mutually agreed to by the parties prior
to commencement of SUPPLIER's Installation. Should CINGULAR desire that SUPPLIER
assist CINGULAR in performing CINGULAR's acceptance tests, SUPPLIER
participation shall be upon terms and conditions, including prices, mutually
agreed to by both parties. If CINGULAR does not furnish SUPPLIER in writing a

any such audit, and the responsibility for any additional tax, penalty or
interest resulting from such audit shall be determined in accordance with the
applicable provisions of this Section. SUPPLIER's failure to comply with the

those taxes.

where SUPPLIER is providing Services. SUPPLIER shall issue appropriate warnings
to inform and educate its employees, agents, subcontractors, other invitees, and
employees of any of them, entering CINGULAR's facilities of the above
information in accordance with applicable Laws and Regulations. SUPPLIER and

The MCPS2000 system provides visual status information through front-panel LED
indicators. Status information is also transmitted via a front-panel RS-232 port
using Spectrian's optional Graphical User Interface program.

The MCPS2000 can also be optionally equipped with additional alarm and control
interfaces, including dry-contact or TTL alarm connections RS-232 or RS-422
interfaces to network operations and administration systems.

CONFIDENTIAL TREATMENT

The default alarm limit settings and analog protection circuit operation for the
MCPS2000 family of MCPA amplifier systems is summarized below. The information
contained herein is provided for reference only. Guaranteed specification limits
must be negotiated between prospective customers and Spectrian. There are three
levels of the alarm/protection hierarchy:

•Analog Protection Circuits—Configured in hardware design to protect the MCPA.

•MCPA Module Alarms—Most are software configurable for specific applications.

•Amplifier System Alarms—Summarizes MCPA and Alarm Management Module status.

In general, the analog protection circuit limits are set by design, and may not
be changed. However, the MCPA alarm limits are software configurable, and may be
tailored to meet customer alarm specifications. Individual MCPA alarms are not
displayed on the module front panel, but are accessible through Spectrian's
Graphical User Interface (GUI) software. System level alarms are summaries of
the module alarm status (minor/major/critical), as well as the Amplifier
Management Module (AMM) and the communication link between the modules and the
AMM.

5.4.1    MCPA Module Analog Protection Circuits

The MCPS2000 MCPA module design incorporates analog protection circuits to
prevent MCPA module damage by common misuse conditions. The circuits react
automatically to the conditions shown in the table below with the limits set as
noted. These limits are not adjustable by software configuration.

Table 1 Analog Protection Circuits

5.4.2    MCPA Module Alarms

The set points, delay, reset points, and latching conditions of all three types
of alarms are software configurable. Some Minor alarm settings can be specified
by the customer but must be agreed upon between the customer and Spectrian prior
to installation or modification. Alarm limits for Major and Critical Alarms are
fixed and can not be modified, insuring long term reliability of the MCPA
module.

5.5    Amplifier Management Unit

The Amplifier Management Unit (AMU) monitors and controls performance of the
various subassemblies within the RF module. The AMU provides operating status
information via front panel LEDs. Within a multi-module system, the AMU provides
status to the MCPS2000 AMM.

5.6    Hot Swap and Power Save

The MCPS2000 is designed to enable system maintenance without removing the
amplifier from service. In multi-module, high power systems, the RF modules can
be hot-swapped during operation without affecting calls in process. In addition,
the individual amplifier modules can be remotely disabled and enabled for power
save during low traffic periods via the RS-232 interface.

5.6.1    Constant Gain

A unique feature of the MCPS2000 system is its ability to maintain constant gain
when any MCPA module is removed or disabled. The AMM determines which MCPA
module is removed or disabled and automatically balances the system to provide
constant gain thereby eliminating the need for re-calibration of the system
gain.

5.7    Graphical User Interface

The graphical user interface (GUI) for the MCPS2100 provides system input and
control as well as report current operating conditions. Through this interface
the user can modify operating parameters, configuration information, and monitor
the current health of the system. In a multi-module configuration the GUI
provides both an overall system interface (via AMM) as well as direct access to
the individual RF modules.

5.8    Mechanical

The MCPS200 system can be provided with a variety of product specific
applications including: stand-alone for integration into existing equipment or
in a multi-sector indoor transmit cabinet of up to 3 sectors. A
telecommunications rack is also available. The indoor transmit cabinet, or
ITCS2000 system includes the MCPS2000 shelf and all necessary input hybrid
combiners and Tx filters for a complete system solution. For Ericsson
applications, all RF and DC connections are provided from the front panel
access. Numerous cable kits have been designed to enable the customer to provide
custom product applications within select OEM radio equipment.

5.9    Intermodulation Data

The following pages show test data showing the intermodulation performance of a
350-watt system with 24 carriers. The data shows IMD performance of—65 dbc. In
addition, Spectrian has done simulation to determine the effects of downlink
power control and have determined no detrimental effects in performance. Since
Spectrian's multi-carrier amplifiers are designed for high PK-Avg ratio of >10
dB, the EDGE carriers do not downgrade Spectrian MCPA performance.

Appendix 3
Performance Report Card
August 14, 2001

This document provides the framework from which the Performance Report Card will
be measured. The intent of the Performance Report Card is to measure MCPA
Vendor's performance in areas critical to Cingular. MCPA Vendor's performance
below the set target may lead to contract termination as specified below for the
applicable area. Results shall be tracked monthly with quarterly written
reporting for the entire Performance Report Card unless otherwise specified in
this Appendix.

Performance Report Card areas consist of the following:

1.System Down Time

2.Module and Delivery Performance

3.Repair and Return

4.Vendor provided Webpage development and progress

5.Customer Service Requests (CSRs)

6.PRD (Product Requirement Document) Delivery Time Measures

Definition of Systems

Systems to be included in the performance measurements for down time are those
systems directly impacting the ability to collect revenue. Depending on the
hierarchical position of a System in the Network, different weight may be
applied when calculating liquidated damages.

Systems to be included in the Performance Report Card are:

Network Element

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

  Description

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

MCPA System   Consists of MCPA modules, subracks, combiners, filters MCPA Module
  Multicarrier Power Amplifier Subrack   Mechanical hardware and software for
combining multiple MCPA modules Hybrid Combiner   Passive resistive network for
combining multiple RF signals onto one RF output prior to input into MCPA system
Rack   Mechanical hardware for stacking multiple subracks

1.    System Down Time

A.    Definition   
System Down Time is defined as unscheduled, MCPA Vendor attributed System
Downtime and/or Complete Cellsite Failure (CCF). CCF is defined as 95% or
greater call or transaction inhibition or any CCF related inability to collect
revenue. MCPA Vendor and Cingular agree to track System Down Time for all
Cingular markets as defined in this Agreement.

B.    System Down Time Determination

Sector or cells' related outage downtime will be measured from switch logs.
Downtime for CCFs will be retrieved from site alarm report. In the event of CCF
downtime, a post-CCF meeting between Cingular and MCPA Vendor will be held to
mutually agree upon downtime minutes for each incident. CCF will be measured on
Cingular Statistical Reporting system, billing records and transaction reports.

[***] Confidential treatment requested pursuant to a request for confidential
treatment filed with the Securities and Exchange Commission. Omitted portions
have been filed separately with the Commission.

1

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

CONFIDENTIAL TREATMENT

Non-cell related system downtime will be measured as the time the services were
unavailable for use at an application level, as measured by system logs.
Customer and system impact for CCFs can be retrieved from switch reports from
associated network elements. In the event of CCF downtime, a post-CCF meeting
between Cingular and MCPA Vendor will be held to mutually agree upon downtime
minutes for each incident. In the event that Cingular experiences a CCF on a
System Element in a redundant solution without causing any degrade of service
for the end-user, this shall not be tracked in this report card.

Both cell and non-cell downtime will be measured per quarter per included System
Element. In the event of a cell failure, lower hierarchical nodes are not
included in downtime calculations in order that only the root cause is measured.

5.    CUSTOMER SERVICE RESPONSE (CUSTOMER SERVICE RESPONSE)

MCPA Vendor's RMA (Returned Merchandise Agreement) process will be used to
record, track and measure CSR response times, and problems encountered by
Cingular. MCPA Vendor will provide Cingular with quarterly written reports and
root cause analysis for all Cingular CSRs using four (4) priority levels with
associated resolution times as defined in the "Customer Support Services"
Appendix D of this Agreement.

A.Resolution Periods for CSRs.

The "Resolution Period" for each CSR shall begin at the time when MCPA Vendor is
notified by Cingular of a problem requiring assistance. MCPA Vendor will issue a
CSR record for every such event.

The Resolution period ends upon earlier of:

1.The availability to Cingular of any approved permanent or temporary solution
("Solutions", including but not limited to changes, corrections, fixes,
workarounds or other actions) by Cingular which resolves the defect or mitigates
the defect until such time as the permanent solution is delivered; or

2.The parties' agreement that such CSR needs no further attention.

The Resolution period specifically excludes time periods in which:

a.MCPA Vendor and Cingular agree to temporarily suspend analysis of the reported
problem while waiting for Cingular to supply or allow MCPA Vendor to retrieve
additional requested information or data from Cingular (CSR Customer Pending
state);

b.MCPA Vendor has solved the problem and the solution is available for delivery
and Cingular agrees that it is not necessary to deliver the solution in advance
of its delivery in a standard software update package. (CSR Solved state);

c.MCPA Vendor has delivered the solution to Cingular (CSR Delivered state);

d.MCPA Vendor has delivered the solution to Cingular and Cingular has verified
the solution. (CSR resolved state )

d.MCPA Vendor and Cingular can not in good faith agree as to whether or not the
provided solution corrects the reported problem (CSR Impasse state), ; or

e.If the CSR requires feature development and is requested by MCPA Vendor to be
converted to a PRD with a software release confirmed by MCPA Vendor, per
Section 7 below, then the CSR will be closed.

[***] Confidential treatment requested pursuant to a request for confidential
treatment filed with the Securities and Exchange Commission. Omitted portions
have been filed separately with the Commission.

3

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

CONFIDENTIAL TREATMENT

MCPA Vendor is committed to use all reasonable efforts to identify temporary
program changes or work-around procedures to minimize the effects of the
defects. Cingular and MCPA Vendor may mutually agree to negotiate an extension
on CSRs that describe highly complex problems requiring additional time to
resolve.

B.Resolution Times

The resolution times to which MCPA Vendor agrees to adhere to are as follows:

Critical priority   [***] High priority   [***] Medium priority   [***] Low
priority   [***]

C.Reassignment of CSRs

In the event, MCPA Vendor and Cingular jointly determine that the resolution of
the CSR requires (i) a new feature (a billable enhancement to the system which
would clearly generate revenue or significantly reduce operating costs to
Cingular) or(ii) an enhancement (a modification to an existing capability, or to
support an existing capability that would increase efficiency or ease of use)
rather than a non-compliance to Specifications, and MCPA Vendor desires to
reassign the existing CSR ticket to the Cingular PRD process, then MCPA Vendor
will notify the CSR originator and Cingular Vendor Management by e-mail and the
parties shall mutually agree upon a date that the PRD process will begin.

6.    PRD (Hardware and Software) Delivery Time Measure

Once the Cingular's PRD is transitioned to an MCPA Vendor's MRD (Market
Requirement Document), the MRD will go through a feasibility study exercise. If
the MRD is approved for development, MCPA Vendor will define the availability in
which the MRD will be delivered.

MCPA Vendor will be measured by meeting the release dates of all MRDs (hardware
and/or software). Furthermore, MCPA Vendor will be committed to implementing a
process to release features and/or enhancements between versions releases.

7.    Critical HW Failures for Base Stations

MCPA Vendor and Cingular agree to work together to define a process to track the
MTBF (Mean Time Between Failures) values for all critical MCPA equipment, within
60 days after execution of this agreement, as needed for previous sections.
