10.  The revised and modified Development Agreement between BT and WIN contains
     the following WIN Milestones:

                                 WIN Milestones

A    25 Sep 95      Provide a platform to BT that allows core transceiver 
                    testing including 2 Mbps and 6 Mbps operation with a 96 kbps
                    control channel including an active POTS filter. BT would
                    test this platform for DMT transmission performance results
                    and send the test results to WIN.

B    15 Dec 95      Provide a first prototype system to BT that includes an 
                    access multiplexer and ADSL line cards to allow performance
                    testing of the line cards and functional testing of the
                    multiplexer in a static configuration. The system would
                    consist of 1 shelf, 2 sets of common equipment cards and 2
                    sets of ADSL line cards.

C    15 Mar 96      Provide a pre-production reference model that
                    passes performance testing and has been parametrically
                    tested. This system would consist of the same number and
                    type of components as milestone B and would be expected to
                    pass the acceptance test plan established by that time.

D    28 Jun 96      Provide pilot production systems to BT consisting of 2
                    multiplexers each equipped with two sets of line cards.
                    These systems would be representative of production systems.

11.  In order to accomplish the WIN Milestones, WIN requires the performance of
     ADI and AWARE to develop a DMT transceiver capable of at least 2.048 Mbps
     and 6.144 Mbps downstream in addition to a 96 kbps bi-direction control
     channel with associated ATM and ADSL overhead. This transceiver must be
     capable of the performance specified in BT "ADSL Product Requirements for
     BT/Westell Development Contract MC589932". In order to accomplish this, ADI
     and AWARE commits to the following Milestones:

                    and AFE2 boards to support the transceiver configuration and
                    operation at 2 Mbps and 6 Mbps (ATM) rates with 96 kbps bi-
                    directional control channel.

4.   12 Aug 95      Aware to provide WIN with TICL interface software in order
                    to support Westell hardware and software integration in
                    Aurora, Illinois.

5.   21 Aug 95      ADI to provide WIN with samples of all IC's necessary to
                    complete assembly of six transceivers (three lines).

6.   15 Sep 95      ADI to provide WIN with X-Grade IC's for eight
                    transceivers (four lines).

7.   28 Sep 95      AWARE to provide WIN with 1.0 software capable of
                    TICL controlled configuration, diagnostics and status
                    required to support transceiver performance in accordance
                    with the BT requirements.

          The ADI and AWARE commitment milestones represent the minimum set of
          milestones necessary to execute the commitments for WIN and Westell
          DMT ADSL customers. Delay in keeping milestone commitments will impact
          WIN competitiveness in the marketplace and customer satisfaction.

     parties agree that the terms and conditions of this Agreement shall
     prevail, notwithstanding contrary or additional terms, in any purchase
     order, sales acknowledgment, confirmation or any other document issued by
     either party including the Schedules attached hereto.

20.  Miscellaneous Provisions

(a)  This Agreement shall be construed, governed, interpreted and applied in
     accordance with the laws of the Commonwealth of Massachusetts, USA, except
     that questions affecting the construction and effect of any patent shall be
     determined by the law of the country in which the patent was granted.

(b)  No provision of this Agreement is intended to conflict with any law, and
     the provisions should be construed in a manner that will uphold their
     validity. In the event that any provision is found to be contrary to any
     law, it shall be deemed unenforceable, and the parties or the court shall
     substitute a lawful provision in its place which is equitable and which, to
     the extent possible, reflects the original intent of the parties. Unless it
     would be inequitable to do so, all other provisions of this Agreement shall
     remain in full force and effect.

(c)  The failure of either party to assert a right hereunder or to insist upon
     compliance with any term or condition of this Agreement shall not
     constitute a waiver of that right or excuse a similar subsequent failure to
     perform any such term or condition by the other party.

21.  Force Majeure

     Neither party shall be liable for delay in performance or failure to
     perform in whole or in part the terms of this Agreement due to strike,
     labor dispute, act of war, labor shortage, riot or civil commotion, act of
     public enemy, fire, flood or act of God or other cause beyond the control
     of such party.
