      (i)   employees of Developer or, to the extent Nokia has consented to the
            use of subcontractors, employees of such subcontractors; and

      (iii) are subject to Developer's supervision as an employer or, to the
            extent Nokia has consented to the use of subcontractors, subject to
            other sufficient supervision of Developer.

3.4   Subcontractors

      In the absence of advance written consent by Nokia, Developer shall not
      engage any subcontractor or other third party to perform any part of
      Development. However, notwithstanding any such possible consent by Nokia,
      Developer shall remain fully responsible and liable for the performance of
      its subcontractors and shall ensure that the agreements with its possible
      subcontractors impose, as a minimum, the duties and obligations on
      subcontractors with respect to confidentiality and Intellectual Property
      Right ownership issues that are substantially similar to those imposed on
      Developer under this Agreement.

3.5   Production Capability

      The Parties acknowledge that it is the current contemplation of Nokia,
      subject to a successful outcome of Development, to use and/or sell the
      Product(s) in certain volumes and that, consequently, production
      capability and cost effectiveness of the Product(s) are critical factors
      for the successful completion of Development. Developer shall ensure that
      it is, upon the issuance of Certificate of Final Acceptance, able to
      manufacture and deliver to Nokia Product(s) in the quantities specified in
      the Appendix 5 - (Business Model incl. Pricing) or Purchase Agreement. For
      avoidance of doubt it is agreed, that this Agreement constitutes no
      obligation whatsoever for Nokia to purchase any Product(s) or other items
      from Developer.

      Developer warrants that, in the absence of Nokia's clear written
      instructions to the contrary, it shall maintain the manufacturing process
      for the Product(s) or the capacity to promptly implement such process at
      least until [*] years have passed from the beginning of the deliveries of
      Product(s) under the Purchase Agreement.

      Developer shall prepare a documented production recovery plan as set out
      in Appendix 2, which shall define in detail, how Developer has arranged
      the recovery from any incidents affecting any production lines or plants
      related to production of Product(s). Upon request, Developer shall
      promptly provide Nokia with a copy of said recovery plan. Upon reasonable
      notice by Nokia and within Developer's business hours, Developer shall
      further allow Nokia and/or its authorized representative to audit the risk
      management systems of Developer. Developer shall promptly implement all

      implement any Changes required by Nokia and the technical and commercial
      consequences of such Changes irrespective of whether or not the Parties
      have yet agreed on the Change in writing.

      For avoidance of doubt, it is agreed that in case Developer wishes to
      implement any Changes before the Parties having agreed in writing on the

      expense,, provided that such implementation does' not endanger the
      continued proper performance of Development in case Nokia later elects to
      reject the Change or in case the Parties are unable to agree on the
      Change.

      used by Developer for manufacturing of Deliverables, or (iii) the exercise
      by Nokia of any Intellectual Property Rights licensed hereunder to Nokia
      or the exploitation by Nokia of any Intellectual Property Rights
      transferred to Nokia hereunder, provided that (1) Nokia informs Developer
      in writing of any such claim, demand, suit or proceeding without delay,
      (2) Developer is given sole control over the defence thereof and Nokia
      reasonably cooperates in the defence at Developer's expense, and (3) Nokia
      will not agree with the third party to the settlement of any such claim,
      demand, suit or proceeding prior to a final judgment thereon without the
      prior written consent of Developer, which consent shall not be
      unreasonably withheld. Nokia shall have the right to select its own
      counsel to participate in such defence at Nokia's own expense.

      Notwithstanding the Developer's primary right to have control over
      defence, (i) Nokia may take all necessary steps, at the expense of the
      Developer, to defend itself until the Developer, to the reasonable
      satisfaction of Nokia, assigns a counsel and initiates defence in a
      professional manner; and (ii) whenever the third party making such claim
      is a customer to the Developer, Nokia may, at its option and at the
      expense of Nokia, have full control over defence, and the Developer agrees
      to fully cooperate with such defence.

      The foregoing states Nokia's sole and exclusive remedy in the event
      Developer violates or infringes any Intellectual Property Rights of any
      third party during Development, manufacturing or delivery of Deliverables,
      Product(s) and/or modifications thereof hereunder.

      This indemnification does not apply to the extent that (i) infringement
      arises by a combination made a Nokia Indemnitee of Deliverables with other
      products not furnished by Developer except to the extent Developer is a
      contributory infringer, (ii) infringement arises solely from changes or
      modifications made to or from Deliverables by a Nokia Indemnitee, or (iii)
      infringement arises from Deliverables that are made, or methods that are
      used, in accordance with drawings, samples, or manufacturing
      specifications that are designated by a Nokia Indemnitee and Developer
      proves that such infringements arise solely from such drawings, samples,
      or manufacturing specifications that are designated by a Nokia Indemnitee.

      If a claim, demand, suit or proceeding alleging infringement is brought or
      Developer believes one may be brought, Developer shall have the option, at
      its expense, to (1) modify the Deliverable to avoid the allegation of
      infringement, while at the same time maintaining compliance of the
      Deliverable with the requirements set forth under this Agreement, (2)
      replace the Deliverable with non-infringing but equivalent Deliverable,
      which comply with the requirements set forth under this Agreement; or (3)
      obtain for Nokia, at no cost to Nokia a license to continue using and
      exploiting the Deliverable in accordance with this Agreement free of any
      liability or restriction.

      In the event any Deliverable to be furnished under this Agreement is to be
      made in accordance with drawings, samples, or manufacturing specifications
      designated by Nokia and to the extent such Deliverable is not the design
      of Developer, Nokia agrees to settle and/or defend; at its own option and
      its own expense, and indemnify and hold Developer harmless from any cost,
      expense, loss, attorney's fees or damage arising out of any claim, demand,
      suit or proceeding against Developer to the extent such claim, demand,
      suit or proceeding alleges that such Deliverable or drawings, samples, or
      manufacturing specifications designated by Nokia infringes upon any
      Intellectual Property Right of a third party, provided that (1) Developer
      informs Nokia in writing of any such claim, demand, suit or proceeding
      without delay, (2) Nokia is given sole control over the defence thereof
      and Developer reasonably cooperates in the defence at Nokia's expense, and
      (3) Developer will not agree with the third party to the settlement of any
      such claim, demand, suit or proceeding prior to a final judgment thereon
      without the prior written consent of Nokia, which consent shall not be
      unreasonably withheld. Developer shall have the right to select its own
      counsel to participate in such defence at Developer's own expense.

            Purchase Agreement, which breach is not duly remedied within a
            reasonable time fixed by Nokia, which period shall not be less than
            [*] days, in a written notice drawing the attention of Developer to
            the breach and requiring the breach to be remedied; and/or

            or ceasing to conduct any material part of its business relating to
            any Product(s), and (B) in connection with any of the foregoing
            Developer breaches its obligation to accept and fulfill orders for

            more than [*] week, in a written notice drawing the attention of
            Developer to the breach and requiring the breach to be immediately

      Manufacturing License shall terminate. Upon termination of Nokia's right
      to exercise the Manufacturing License, Nokia shall return the

      and to the extent that such delay or non-performance is due to an event of
      Force Majeure.

      If an event of Force Majeure results in delay or non-performance of a
      Party for a period of [*] or longer, then either Party shall have the
      right to terminate this Agreement with immediate effect without liability
      towards the other Party.

17    CONFIDENTIALITY

17.1  General

      For avoidance of doubt and notwithstanding this Clause 17, it is agreed
      that the confidentiality undertakings provided for in this Clause 17 do
      not limit in any way whatsoever Nokia's rights to utilize and disclose
      Deliverables, Product(s), Specifications or other outcomes of the
      Development or parts thereof in compliance with Clause 10 (intellectual
      Property Rights and Indemnification) and Clause 11 (Manufacturing Rights
      and Information) above.

      Each Party ("Receiving Party" for the purposes of this Clause 17) shall
      not, except to the extent required by law, disclose to third parties nor
      use for any purpose other than for the proper fulfillment of the purpose
      of this Agreement and/or the Purchase Agreement any technical, financial
      or commercial information ("Information") received from the other Party
      ("Disclosing Party") in whatever form under or in connection with this
      Agreement without the prior written permission of the Disclosing Party.
      The above mentioned limitations shall not apply to Information which, as
      evidenced by the Receiving Party:

      a)    was in the possession of the Receiving Party prior to disclosure
            hereunder; or

      b)    was in the public domain at the time of disclosure or later became
            part of the public domain without breach of the confidentiality
            obligations herein contained; or

      c)    was disclosed by a third party without breach of any obligation of
            confidentiality owed to the Disclosing Party; or

      d)    was independently developed by personnel of the Receiving Party
            having no access to the Information of the Disclosing Party.

      Without prejudice to the generality of the foregoing, each Party agrees
      not to use any of the Information or technology of the other Party for any
      use or purposes except those expressly specified herein.

17.2  Affiliates, Personnel and Subcontractors

      Affiliates of a Party hereto engaged in the performance of this Agreement
      shall not be deemed to be third parties for purposes of this Clause 17 on
      condition that disclosure of Information occurs on a need to know basis
      only and that the respective Party ensures full compliance by such
      Affiliates of all of the provisions of-this Clause 17.

      Developer shall not disclose any Information of Nokia to its
      subcontractors, unless Nokia has consented to the use of any such
      subcontractor in writing. Each Party shall limit access to Information of
      the other Party to those of its subcontractors and personnel for whom such
      access is reasonably necessary for the proper performance of this
      Agreement and/or the Purchase

17.4  Conflicting Provisions

      To the extent that the terms of a Non-Disclosure Agreement between the

      Non-Disclosure Agreement.

17.5  No Publicity

      In the absence of prior written consent by the other Party, neither Party
      shall make any publicity on, press release of or reference to this

18    TERM AND TERMINATION

18.1  Term of the Agreement

      This Agreement shall become effective upon the Effective Date and shall
      apply retroactively also to all Development having been carried out prior
      to the Effective Date. This Agreement shall continue to be effective until
      either:

      (i)   Development has been fully carried out and Certificate(s) of Final
            Acceptance have been issued by Nokia and the Parties have, if so
            requested by Nokia, complied with Clauses 13.2 and 13.3 above; or

      (ii)  this Agreement has been terminated by either Nokia or Developer
            pursuant to Clause 18.2 or 18.3 below or terminated by Nokia
            pursuant to Clause 8.3 above.

18.2  Termination

      This Agreement may be terminated by either Party with immediate effect by
      sending a written notice of termination to the other Party, if said other
      Party:

      (i)   becomes insolvent, is declared bankrupt or becomes the subject of
            dissolution, liquidation (other than for the purpose of
            reconstruction or amalgamation), receivership or bankruptcy
            proceedings, whether voluntarily or involuntarily, or applies for
            judicial or extra-judicial settlement with creditors, makes an
            assignment for the benefit of creditors, or takes or suffers any
            similar action in consequence of a debt or otherwise discontinues
            its business relating to Development and/or Product(s); and/or

      (ii)  is in breach of any of its material obligations under this
            Agreement, which breach is not solely attributable to the
            terminating Party and has failed to rectify such breach within [*]
            days of having received written notice of such breach and the
            intention of the terminating Party to terminate this Agreement, if
            the breach is not rectified (or, if such breach is not capable of
            being rectified within such time, if the Party fails to commence to
            rectify such breach within such time).

18.3  Termination by Nokia

      to Developer, in case of:

      (i)   a change of ownership in or effective control over Developer or its

            18.2 above or Nokia terminating this Agreement based on Clause
            18.3(iii) above Nokia shall not be relieved from its obligation to
            effect Payments having accrued or become due prior to the date of
            the termination.

18.5  Surviving Clauses

      Any terms and conditions of this Agreement that by their nature or
      otherwise reasonably should survive termination, cancellation or other
      expiry of this Agreement shall survive any termination, cancellation or

1.0 PURPOSE

      The purpose of this document is to define and document the requirements of
      Appendix 1 for the Development Agreement (DA) between Nokia Networks and
      Endwave Corporation. This DA serves to develop a series of Microwave Units
      (MWUs) for use in the Nokia [*] products at [*] GHz, [*] GHz, [*] GHz, and
      [*] GHz. The [*]MWUs shall meet the class 2 level design requirements as
      called out in Nokia's "[*] GHz Integrated Microwave Unit Specifications",
      referenced below.

      Appendix 1 defines the functionality of the MWU transceiver, the
      components that make up the MWU, and the process technologies to be used.
      The discussion will be broken into two parts covering the millimeter wave
      section and the DC/IF printed circuit assembly.

3.0 APPENDIX 3 - PROJECT PLAN

3.1 PROJECT SCOPE

      The objective of this project is to redesign the [*] currently produced by
      Endwave to meet the performance requirements as defines in Nokia
      specification E10014774QE_E0. [*] wave bands, [*], and [*] GHz, are to be
      redesigned in this effort. The [*]MWUs shall meet the class 2 level design
      requirements. Each design will be form factor compliant with the current
      production MWU's. The project will include a software development effort
      to support

      integration testing and qualification of the new MWU's in the [*]. Radio
      testing will be done to a depth and level mutually agreed to during the
      development effort.

      The integration test software at Endwave shall meet the requirements of
      Nokia MWU Integration Test Plan, document number 133-004238_00. Minor
      modifications are planned to the production test sets to incorporate new
      testing capability per the [*]specification. These changes will be defined
      during the development effort.

      The [*]MWU's shall be designed to conform with Nokia specific and new EU
      environmental directive (ROHS, WEE) requirements defined in Appendix 6.
      Implementation of all environmentally safe materials and processes shall
      occur in phases, and will fulfill the requisite timetables. For example,
      lead free PCB finish will be implemented in the initial design phase. Lead
      free solder and components will be incorporated at some secondary phase.

      Endwave does not expect the need to qualify any new processes for this
      design. Any changes in processes for the product are processes either
      Endwave or a subcontractor of Endwave has already qualified for use on
      standard product designs. Therefore, the only testing required on a
      new/changed process will be to ensure unit performance using the new
      process.

</TABLE>

      The scope and deliverables of each project phase is defined in the
      respective process plan(s), greater clarification of each phase is
      outlined later in this document. The following provides a high level
      overview of scope for each phase as it pertains to the [*]development
      project.

3.3.1.1 STEP I - DEVELOPMENT PLANNING / SUPPLIER QUALIFICATION

      During this phase a development agreement will be generated. This
      agreement will define how Nokia Networks and Endwave Corporation will work
      together in the development of the [*]product as described in the Project
      Scope section above. At the end of this phase both parties will mutually
      agree on a contractual Development Agreement, Product Definition, Project
      Plan, Project Milestone Deliverables, Quality Plan, Business Model,
      Environmental Model, and Contact List.

3.3.1.2 STEP 2 - ENGINEERING DESIGN / MIN - MODULE ARCHITECTURE AND DESIGN

      A development phase of the project where engineering design and analysis
      is conducted with the goal of meeting the product performance
      requirements. At the completion of this phase, a completed design of the
      MWUs will be done to a level to build Design Validation units.

3.3.1.3 STEP 3 - ENGINEERING VERIFICATION / PROTOTYPE PHASE

      Typically during this phase, prototype units are assembled and tested to
      verify their performance against expected performance based on analysis.
      On this project no prototype units will be assembled and tested. This
      phase will not be performed and any pertinent deliverables will be moved
      to another phase as detailed in later in this document and Appendix 2.

3.7 RESOURCE PLAN

3.7.1 PERSONNEL RESOURCE PLAN

      A resource plan identifying key personnel required to support this project
      has been generated. As part of defining the project team as shown in the
      section, Organization of the Project, each functional organization within
      Endwave was informed about the scope and timeline of the [*]development
      effort. During monthly Endwave internal project reviews, management of
      these various organizations will be updated about current and future needs
      of resources to support this project from kickoff to completion.

3.7.2 EQUIPMENT RESOURCE PLAN

      With the recent completion of the Nokia Block II effort, and the ongoing
      production of [*], no significant additional equipment resources have been
      identified, except to support the upgrade of the Integration Test station.
      This equipment has been identified and budgeted for in the project budget.

3.8 GANTT CHARTS

      As a means to track the progress of the development effort, a detailed
      project schedule has been generated in MS Project. A plot of the schedule
      in Gantt Chart format will be provided as an attachment to this document.
      This schedule will be updated regularly as required per the Endwave Full
      Scale Design and Development Process.

3.9 PROTOTYPE REVISION MATURITY AND TOTAL QUANTITY (PLAN)

            Nokia microphonics specification for the complete outdoor unit is
            E10013978QE_00.

            This item is tested by Nokia at system level. The VCO must meet this
            system level specification tested and approved by Nokia.

            In case of significant changes in the mw module mechanical and
            electrical construction, the effect of the modifications on the
            system level microphonics performance must be verified and approved
            by Nokia.

            The supplier shall on a sample basis monitor that the performance
            does not degrade.

      1.24. Phase hits

            VCO must meet the Nokia system level specification for residual bit
            errors during temperature cycling. See temperature cycling. See
            temperature ranging in specification item 6.4.

                          Class 2 and 3:                [*] kHz

            This item is finally tested and approved by Nokia at system level.
            Supplier must during development be able to show and verify that
            basic design meets this specification.

            Phase hits are sudden changes in the output signal that are caused
            e.g. by bad contacts and thermal expansion or mechanical stresses
            expiring.

                      Class 3: TX output power levels above [*] dBm      [*] dBc

The LO leakage cancellation is based on the closed loop control by ENV_MEAS
signal coning the Itx and Qtx biasings. The internal isolation of the mw module
from LO to PA inside the module must not degrade the LO leakage to be worse than
[*] dBc at the mw module output.

2.    FILE/RECORD SYSTEM

      EEPROM has a simple file (or record) system as shown below.

Ach  06h  27h  6Eh  01H  FFh  10h

</TABLE>

      -     Checksum is calculated by summing all the bytes in the record (byte
            by byte) except the checksum itself (overflown bits are discarded)

      -     Size is the number of the bytes in the record excluding Checksum

      -     Code ID identifies the record (see Chapter 3.1 for details)

      -     Attribute is a bit coded byte, which specifies the format of the
            data (see Chapters 2.1, 3.1 and 3.3 for details)

      -     Protection is a bit coded byte, which specifies the read/write
            protection (see Chapter 2.2 for details)

      As an example, the content of "MWU Division Ratio" record is described:
      The division ratio of the [*]GHz module is [*] (TX frequency / FD!V
      frequency) and the associated attribute byte is 0000 0001(in binary
      format), code ID is [*] (decimal value),and protection byte is [*] (in
      binary format). It follows that the size is then 6 bytes and the check sum
      is [*] ((binary value).

      The records are stored in the EEPROM sequentially starting with the first
      record and first byte available. Before starting the writing procedure,
      the memory content should be erased with an initialize procedure available
      for the memory chip used.

      Note, that record "MWU Time Counters" is not used by the MWU supplier and
      these files should be stored with zeros as data values, whereas, Code ID
      and size of the file should be stored as required.

2.1   ATTRIBUTE

      Attribute byte specifies the value type used (see Chapters 3.1 and 3.3)
      and whether a meaning of data is included or not. IN MWU EEPROM no meaning
      (zero) is added to the records.

0           0          Low power     [*]
</TABLE>

      TXPWR voltages multiplied by [*]are stored using two bytes for each value,
      and then the measured output power in dBm multiplied by [*]is stored using
      [*]bytes per each value. [*]data points per scaling value are saved.

      The data is stored by writing at first all scaling values, then all
      voltage values, and finally, all power values. Scaling runs from the
      highest value to the lowest, and voltage runs from the lowest value to the
      highest value.

      Scaling is stored in unsigned integer format ([*]), voltages as unsigned
      integers ([*]), and powers as signed integers ([*]).

      Total data length is [*].

      When the [*] MHz duplex spacings are combined in one high and one low band
      [*] GHz MWU, then one calibration table for Rx gain and Tx power
      calibration do not provide the needed accuracy. In this case the MWU will
      have two calibration tables for Rx gain and Tx power calibration values.
      These additional tables will be written after the other data previously
      defined in this document. The `End of data' record (EOF) shall be written
      after the last record. This appendix does not apply to the [*] GHz [*] MHz
      variant.

      The first MWU RX Gain Calibration record (Code ID 10052) shall represent
      the Rx frequencies and gain values corresponding with the [*] MHz IF
      frequencies and the first MWU TXPWR Calibration (Code ID 10058) record
      shall represent the TX power calibration table associated to this same
      frequency range.

      The second MWU RX Gain Calibration record (Code ID 10062) shall represent
      the Rx frequencies and gain values corresponding with the [*] MHz IF
      frequencies and the second MWU TXPWR Calibration (Code ID 10063) record
      shall represent the TX power calibration table associated to this same
      frequency range.

      This appendix does not apply if one MWU variant only covers [*] MHz or [*]
      MHz duplex spacings. In this case the original MWU EEPROM specification
      should be applied.

SPECIFICATION FOR MECHANICAL SENSITIVITY OF THE FLEXIHOPPER RADIO RELAY TERMINAL

1.    GENERAL

      The mechanical sensitivity of the [*] relay family is specified for a
      complete terminal installed into its enclosure. Possible bit errors caused
      by mechanical vibrations are detected from a radio channel with a BER
      meter. The mechanical sensitivity of the terminal is separately tested
      when it is operating as a receiver or as a transmitter of a hop.
      Specification is the same for both case.

2.    KNOCKING DEVICE

      2.1   PENDULUM TYPE HAMMER

      A weight with a mass of [*] kg is attached to a [*] hanging from its upper
      end. The weight which is acting as a hammer has a tip made of [*], whose
      hardness [*]. The shock is caused by raising the hammer from its initial
      free-hanging position to distance [*] and released, letting the hammer hit
      the desired spot of the terminal body.

      2.2   KNOCKING SPOT

      Most sensitive spot of the terminal found by knocking it with an ordinary
      plastic hammer.

      2.3   ENERGY OF THE SHOCK

      The energy will be [*] with the pendulum hammer.

      2.4   REPETITION OF THE SHOCKS

      Series of [*] shocks

      2.5   NUMBER OF SHOCKS CAUSING ERRORS IN THE KNOCKING SERIES

      [*] erroneous results are allowed.
