                              TECHNOLOGY AGREEMENT

         This Technology Agreement is made this tenth (10th) day of June, 1996
("Effective Date"), by and between AWARE Inc., with offices at One Oak Park,
Bedford, Massachusetts ("AWARE") and BROADBAND TECHNOLOGIES, INC., with offices
at 4024 Stirrup Creek Drive, Durham, North Carolina ("BBT").

         RECITALS:

         A.       Aware is a developer of copper based technology for
                  high speed transmission systems.

         B.       BBT designs, manufactures and markets telecommunica-
                  tions hardware and software that enables network
                  operators to provide a switched digital fiber optic
                  broadband network.

         C.       Both parties desire to enter into an agreement whereby AWARE
                  will develop and deliver to BBT, certain prototypes
                  incorporating DWMT technology for upstream FTTC/VDSL
                  applications in BBT's FLX platform.

         Now therefore, in consideration of the mutual covenants contained
         herein, the parties agree as follows:

1.       DEFINITIONS

         1.1      "Agreement" means this Technology Agreement and its appendices
                  attached hereto, as they be amended from time to time.

         1.2      "DMT" means a modulation scheme that breaks available
                  bandwidth into narrow subbands to ensure reliable data
                  transmission, even when noise affects certain areas of the
                  available spectrum.

         1.3      "VDSL" means very high speed digital subscriber line.

         1.4      "DWMT" means a modulation scheme similar to DMT that uses
                  wavelet transformers rather than fast fourier transformers.

         1.5      "FTTC" means fiber to the curb.

         1.6      "Most Favored Customer" means that at all times that BBT is
                  purchasing product based on Aware DWMT technology, Aware will
                  make reasonable efforts to assist BBT with Aware's exclusive
                  silicon foundry, with price, delivery dates and other terms
                  and conditions not less favorable than the corresponding terms
                  and conditions granted by Aware's exclusive silicon foundry to
                  any other customer for the same or substantially similar
                  product.

                  WARRANTIES OF MERCHANTABILITY, NON-INFRINGEMENT, AND FITNESS
                  FOR A PARTICULAR PURPOSE.

         6.4      Limitation of Liability. EXCEPT WITH RESPECT TO
                  INDEMNIFICATION FOR INFRINGEMENT, IN NO EVENT SHALL THE

                  transportation, facilities, fuel, energy, labor or materials.
                  Time for performance will be extended by Force Majeure.

         9.3      Assignment. Each party shall have the right to assign this
                  contract to any party that acquires substantially all of the
                  business of such party without the consent of the other party.

         9.4      Choice of Law. The construction, interpretation and
                  performance of this Agreement and all transactions under it
                  shall be governed by the laws of the State of North Carolina,
                  excluding its choice of law rules and excluding the Convention
                  for the International Sale of Goods. The parties agree that
                  the provisions of the North Carolina Uniform Commercial Code
                  apply to this Agreement and all transactions under it,
                  including agreements and transactions relating to the
                  furnishing of services, the lease or rental of equipment or
                  material, and the license of software.

         9.5      Jurisdiction. BBT and Aware agree that any action or legal
                  proceeding arising out of this Agreement shall be brought only
                  in a state or federal court of competent jurisdiction in the
                  Commonwealth of Massachusetts and BBT and Aware expressly
                  submits to, and accepts the jurisdiction of, any such court in
                  connection with such action or proceeding and BBT and Aware
                  further consent to the enforcement of any judgment against
                  either party arising therefrom in any jurisdiction in which
                  either party has or shall have any assets.

         9.6      Severability. If any of the provisions of this Agreement shall
                  be invalid or unenforceable, such invalidity or
                  unenforceability shall not invalidate or render unenforceable
                  the entire Agreement, but rather the entire Agreement shall be
                  construed as if not containing the particular invalid or
                  unenforceable provision or provisions, and the rights and
                  obligations of BBT and Aware shall be construed and enforced
                  accordingly.

         9.7      Mediation. If a dispute arises out of or relates to this
                  Agreement, or its breach, and the parties have not been
                  successful in resolving such dispute, the parties agree to
                  attempt to resolve the dispute through mediation by submitting
                  the dispute to a sole mediator selected by the parties or, at
                  any time at the option of a party, to mediation by the
                  American Arbitration Association ("AAA"). Each party shall
                  bear its own expenses and an equal share of the expenses of
                  the

                                       -8-


   9



                  mediator shall hold the existence, content and result of the
                  mediation in confidence. If such dispute is not resolved by
                  such mediation, within thirty (30) days after a party requests
                  mediation, the parties shall have the right to resort to any
                  remedies permitted by law. All defenses based on passage of
                  time shall be tolled pending the termination of the mediation.
                  Nothing in this clause shall be construed to preclude any
                  party from seeking injunctive relief in order to protect its
                  rights pending mediation. A request by a party to a court for
                  such injunctive relief shall not be deemed a waiver of the
                  obligation to mediate.

         9.8      Relationship of the Parties. Neither party hereto will be
                  deemed the agent or legal representative of the other for any
                  purpose whatsoever and each party will act as an independent
                  contractor with regard to the other in its performance under
                  this Agreement. Nothing herein will authorize either party to
                  create any obligation or responsibility whatsoever, express or
                  implied, on behalf of the other or to bind the other in any
                  manner, or to make any representation, commitment or warranty
                  on behalf of the other.

         9.9      Entire Agreement. This Agreement shall incorporate Appendix A
                  and together with the Confidential Non- Disclosure Agreement
                  between the parties shall constitute the entire agreement
                  between them with respect to the subject matter of this
                  Agreement. All references in these terms and conditions to
                  this Agreement or equipment, products, software or information
                  furnished under, in performance of, pursuant to, or in
                  contemplation of, this Agreement shall also apply to any
                  purchase orders issued pursuant to this Agreement. Printed
                  provisions on the reverse side of Aware's purchase orders and
                  all provisions of BBT's forms shall be deemed deleted. The
                  provisions of this Agreement supersede all contemporaneous
                  oral agreements and all prior oral and written quotation,
                  communication, agreements and understandings of the parties
                  with respect to the subject matter of this Agreement.
