                               -------------------
                                     Between
                         Andrea Electronics Corporation
                                       And
                              Analog Devices, Inc.

This Licensing Agreement is entered into this December 19, 2001, by and between
Andrea Electronics Corporation, a New York corporation having its principal
place of business at 45 Melville Park Road, Melville, New York 11747, together
with its subsidiaries and affiliates ("Andrea"), and Analog Devices, Inc., a
Massachusetts corporation having its principal place of business at One
Technology Way, Norwood, MA 02062 ("ADI").

                                    RECITALS

      WHEREAS, Andrea, by itself and through its subsidiaries, has developed and
is the owner of all right, title and interest in, to and under certain patented
microphone enhancing software algorithms (together with enhancements and/or
modifications providing error corrections and minor improvements in features and
functionality, "the Algorithms") that can be used to enhance voice-driven
natural language computer interfaces and telephony applications, among other
things; and

      WHEREAS, ADI desires to offer one or more of the following Algorithms:
PureAudio(R); EchoStop(TM); and DSDA(R), (the "Licensed Algorithms") to ADI's
Coder/Decoder ("CODEC") chip customers for use on personal computers ("PC's");

NOW, THEREFORE, in consideration of the mutual covenants set forth herein and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, and intending to be legally bound, Andrea and ADI (together
the "Parties") hereby agree as follows:

1.    Grant of Licenses; Protection of Goodwill and Reputation; Patents,
      ------------------------------------------------------------------
Copyrights and Trademarks.
-------------------------

1.1   Andrea grants to ADI a worldwide, royalty-bearing license, including the
right to sublicense to ADI CODEC chip customers, Andrea's PureAudio algorithm
and updates for use on PC's, excluding handheld computing devices such as tablet
PCs and PDAs. In addition, Andrea grants to ADI a worldwide, royalty-free
license, including the right to sublicense to ADI CODEC chip customers and/or
end users, to load Andrea's EchoStop and DSDA algorithms and updates for use on
PC's, excluding handheld computing devices such as tablet PCs and PDAs, subject
to said chip customers and/or end users entering into a terms of use agreement
directly with Andrea to enable either or both Licensed Algorithms. Should ADI
desire to use the Licensed Algorithms for purposes or devices other than those
described above, the terms of such use shall be subject to one or more separate
license agreements between ADI and Andrea. Updates shall include minor
enhancements to performance, functionality and features. Except as the Parties
may otherwise agree, ADI may not, modify, translate, disassemble, decompile,
reverse engineer or create derivative works based on the Licensed Algorithms.
The Licensed Algorithms are protected by United States and international
copyright law and treaties, as well as other intellectual property law and
treaties, and ADI is granted no title or ownership rights, in or

<PAGE>

to the Licensed Algorithms, in whole or in part, and ADI acknowledges that title
to all copyrights, patents, know-how, trade secrets and/or any other
intellectual property rights to and in the Licensed Algorithms and associated
documentation are and shall remain the property of Andrea and its successors or
assigns. As such, ADI warrants that it will not sell or sub-license the Licensed
Algorithms except as provided herein.

1.2   Andrea will not market, license or sell the Licensed Algorithms to be
bundled with integrated motherboard and riser card PC configurations during the
term of this Agreement. Notwithstanding the preceding sentence, Andrea may
market, sell or license the Licensed Algorithms for use in electronic equipment,
including PC's, where the Licensed algorithms are not bundled with integrated
motherboards or riser cards. Specifically, Andrea may market, sell or license
the Licensed Algorithms for use with specific applications, and/or aftermarket
audio input devices.

1.3   In consideration for the exclusive arrangement described in Section 1.2,
ADI will represent to the marketplace, including PC original equipment and after
market customers, that Andrea is ADI's "Preferred Partner". As its Preferred
Partner, ADI, when engaging in marketing efforts, will highlight the benefits
and advantages to the customer of selecting products equipped with Andrea
hardware and/or software audio input technologies, and where ADI has been given
the discretion to select the audio input provider, ADI will select Andrea under
similar terms, conditions and circumstances.

1.4   It is expressly understood by each of the Parties that the goodwill and
superior reputation enjoyed by the other is of ultimate importance to the other.
Each of the Parties agrees to use its best efforts to protect the other and to
avoid any action or inaction that may adversely affect the other's goodwill,
reputation or image.

1.5   Each of the Parties will use its best efforts to protect the patents,
copyrights, trademarks or other intellectual property of the other. At no time,
either during the term of this Agreement or subsequent to its expiration or
other termination, may either party utilize any of the other's names, logos,
patents, copyrights or trademarks except as authorized elsewhere in this
Agreement or as otherwise agreed to in writing between the Parties.

1.6   In order to facilitate the integration of the Licensed Software and
updates thereto bundled with ADI's CODEC products, Andrea will provide
reasonably necessary support at no charge to ADI.

2.    Royalty.
      -------

2.1   In consideration of the license granted under this Section 1.1, ADI shall
pay to Andrea a royalty equal to [*******] U.S. dollars ($[*******]) per year.

(15) days after the execution of this Agreement. Payment for each subsequent
Term, if applicable, shall be payable and due on a quarterly basis in equal

3.    Joint Promotion. During the term of this Agreement, ADI and Andrea shall
      ---------------
promote their relationship contemplated hereby and the complementarity of the
Licensed Algorithms and ADI's products through, by way of example only, press
releases, trade shows agreed upon by the Parties, and in relevant collateral
material. All press releases, trade show material and collateral material prior

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

5.1   The term of this Agreement shall commence on May 1, 2002 hereof and shall
continue for a period of one (1) year and shall thereafter automatically renew
for additional one year periods unless ADI expresses its desire not to renew in

than thirty (30) days to effect a cure, the breaching party fails to commence
and continue in good faith efforts to cure such breach, provided that such cure
shall be effected no later than sixty (60) days after receipt of such notice of
such breach, the non-breaching party may terminate this Agreement by written
notice to the other party.

5.3   The termination of this Agreement shall not affect any claim, right or
remedy that a party has against a breaching party.

BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE, WITH REGARD TO THE SOFTWARE. IN NO EVENT WILL EITHER PARTY
BE LIABLE TO OR THROUGH ANY PARTY FOR INCIDENTAL, INDIRECT, SPECIAL,
CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES OF ANY KIND, INCLUDING LOST
PROFITS, LOSS OF BUSINESS OR BUSINESS INFORMATION, BUSINESS INTERRUPTION, OR

7.2   Andrea has full title and ownership of the Licensed Algorithms and has not
assigned, transferred, pledged or otherwise encumbered the Licensed Algorithms
or intellectual property rights with respect thereto or agreed to do so,
including in the performance of its obligations under this Agreement. The
Licensed Algorithms do not infringe or misappropriate any patent, trade secret,
copyright, mask work or other proprietary right of any third party, and Andrea
is not aware of any invention, product or prior act that would prevent or

or more aspects of the Licensed Algorithms.
