The above timetable is preliminary. Aware and Analog Devices will mutually agree
upon a Final Timetable by November 15, 1995. This will include a detailed
description of each milestone with designation of responsibility to Aware and/or
Analog Devices as appropriate.

If either ADI or Aware misses any of the milestones   in the above timetable by
more than 12 months, then either ADI or Aware may convert the exclusive license
granted under Section 2 of the AMENDMENT TO THE LICENSE AGREEMENT to a
non-exclusive license.

35. The parties agree that this is an exclusive teaming agreement joining Aware
system designs, algorithms and software with ADI DSP and integrated circuits for
ADSL and VDSL being developed by the ADI Division responsible for broadband
communications (currently this is the responsibility of the Communications
Division). Neither party shall enter into a competing agreement with third
parties unless the other party had defaulted in its obligations hereunder or
unless the license granted under the AMENDMENT TO LICENSE AGREEMENT becomes
non-exclusive as provided herein.

36. Both parties acknowledge that at any time ADI may enter into a similar
agreement with a provider of single carrier modulation technology such as
CAP, QAM, and/or QPSK for this application. If this occurs it will not be in 
violation of para. 35.

37. Aware acknowledges that at any time, ADI may have to hire, contact or
acquire third party developers and consultants to complete the work for this
contract, In that event, Aware will agree to work openly with said third
parties. If necessary, appropriate confidentiality and Non-Disclosure Agreements
will be mutually executed between said third parties and Aware.

38. Both parties agrees that in the event the technology developed under this
program and owned by the parties becomes a standard for VDSL then each party
will license to third parties that technology on a fair, equitable and
non-discriminatory basis.

39. ADI agrees to sell Aware up to 5% of the annual production of ADI chipsets
used for VDSL at market prices.

40. ADI and Aware agree to allow one another to review patents applications that
are relevant to VDSL before they are filed.

In witness whereof, the parties duly execute this agreement the day and year set
forth below.

            APPENDIX 2 TO LICENSE AGREEMENT BETWEEN AWARE AND ANALOG
                                 DEVICES, INC.
            DATED SEPTEMBER 1993 AND EFFECTIVE AS OF THIS 26TH DAY OF
                                 SEPTEMBER 1995.

This Appendix 2 is intended to express the license rights and responsibilities
of the parties to intellectual property described and to be developed under a
certain SECOND AMENDMENT TO DEVELOPMENT CONTRACT dated as of the date of this
Appendix 2. The following provisions are not in substitution of any similarly
numbered provisions of the License Agreement but shall be deemed specific to the
intellectual property produced pursuant to the terms of the SECOND AMENDMENT TO
DEVELOPMENT CONTRACT.

1.11 "PROGRAMS" shall mean the SOFTWARE developed by Aware (and all associated
documentation) pursuant to the SECOND AMENDMENT TO THE DEVELOPMENT CONTRACT.

1.12 The term "LICENSED PRODUCTS" is amended to include all ADI products for the
FIELDS OF USE (ADSL or VDSL) being developed by the ADI Division responsible for
broadband communications (currently this is the responsibility of the
Communications Division), including digital and analog chips for ADSL or VDSL
(whether or not such chips incorporate the PROGRAMS or any part thereof.)

1.13 "FIELD OF USE" shall mean "products and technology for data, voice and
video services over copper VDSL, VADSL, BDSL or other copper technologies used
in Fiber to the Curb, Switched Digital Video, Fiber to the Building and Fiber to
the Home architectures" (HEREINAFTER REFERRED TO AS "VDSL").

In the ROYALTY Section:

3.5 For the VDSL rights, privileges and license granted hereunder, ADI shall pay
a license fee and royalties to Aware in the manner hereinafter provided or until
this agreement is terminated.

a. A license fee of $[redact] payable as follows:

             $[redact] upon execution of this agreement.

             [redact] upon completion of the system design and chip 
             set specification (MILESTONES I, 2 and 4 in SECOND 
             AMENDMENT TO DEVELOPMENT AGREEMENT).

b. Royalty payment shall be based on the net selling price of the .VDSL LICENSED
PRODUCTS and shall be calculated as follows:

c. [redact] of the net selling price. Net selling price is defined as the
selling price less any license fees paid to any other valid patent holder. Chips
included in the calculation are all chips developed by and sold by ADI for this
application.

To maintain the exclusive license, for Calendar years 1996 (CY1996) and 1997
(CY1997), ADI shall make prepaid royalty payments as follows:

For CY1996: 
               [redact] payable by 12/31/95. 50% of this payment applies towards
               VDSL LICENSED PRODUCTS sold by ADI in CY 1996.The remaining 50%
               applies toward VDSL LICENSED PRODUCT sold by ADI in CY 1997.

For CY1997:
               [redact]

For CY 1998:
               [redact] payable by 12/31/1997.


                                       2

These are prepaid royalties. In the event that royalties due Aware exceed this
amount ADI will start making payments quarterly based on the amount of royalties
due Aware above and beyond the prepaid amount.

In addition, to maintain the exclusive license, ADI shall make minimum calendar
year royalty payments equal to royalties due on [redact] of the available
non-captive market for VDSL transceivers based on the Aware/ADI approach. The
balance of the minimum royalty payments shall be due on the 31st of December of
each year.

Payment shall be made net 30 days from the above dates. If a payment is not made
exclusivity granted under Section 2 will end one calendar year from the date of
the last payment.

If ADI can show that a royalty of [redact] does not allow it to compete in the
marketplace then reducing the royalty rate shall be discussed. ADI and AWARE
will engage in good faith negotiations to determine the new royalty rate. Proof
will be in the form of a Full factory cost calculation and market based selling
prices. Full factory cost shall be based on industry standard practices. ADI
agrees to provide Aware with the necessary information and formulae used in the
calculation.

Additionally, as the market develops ADI and Aware jointly may desire to forward
price early generation chip sets to gain market penetration. In this event ADI
will reduce the selling price and Aware will reduce their royalty rate as
appropriate and equitable.

Furthermore, ADI and Aware agree that success in this market may require ADI and
Aware to develop multiple generations of the chip set and variations and
customizations of the base technology. "Base technology" is defined as the VDSL
technology implemented by Aware and ADI under the SECOND AMENDMENT TO THE
DEVELOPMENT CONTRACT.

In the event that Aware chooses, at its discretion, not to assist ADI in cost
reductions and customizations the royalty payment will be reduced by [redact] or
to [redact] whichever is lower and not go below [redact]. In the event that ADI
customizes beyond the base technology without any material involvement by Aware,
the royalty rate will not be reduced but will be based on the proportion of the
chip set, as measured by die area, that incorporates the base codeveloped
functionality. ADI will notify Aware, in writing, of its intention to perform
the aforementioned cost reductions


                                       3

   19


and customizations. Aware will have 45 days to respond and choose to assist or
not to assist ADI.

In the event that ADI does not make the minimum royalty payments, AWARE or ADI
may convert the exclusive license granted for VDSL under section 2.1 to a
non-exclusive license. In the event that the exclusive license is changed to a
non-exclusive licenses, AWARE will not license any other party under terms more
favorable than those given to ADI. In the event that any other party or parties
must be granted a license, such as if the technology becomes a standard or a
large customer requires a second source, the previous clause applies and Aware
shall pay ADI 17.57 of all license fee and royalty payments.

Regarding REPRESENTATIONS AND WARRANTIES of Aware and indemnity for INFRINGEMENT
(Sections 4 and 8 of the LICENSE AGREEMENT), the parties understand and agree
that it may be necessary for ADI to obtain licenses from others to enable ADI to
make, use and sell the LICENSED PRODUCTS.

In witness whereof. the parties duly execute this agreement the day and year set
forth below.
