                              CONSULTING AGREEMENT

THIS CONSULTING AGREEMENT (the "Agreement"), executed as of the 1st day of
August 1998, is hereby made between AMBIENT CORPORATION, a Delaware corporation
having offices at 270 Madison Avenue, New York, New York, 10016 (hereinafter
"ABTG"), and MISSION BAY CONSULTING, INC., a Rhode Island corporation having an
office address at 387 Atwells Avenue, Providence, Rhode Island 02909
(hereinafter "Consultant").

                                  WITNESSETH:

     WHEREAS, ABTG desires to obtain certain financial consulting services, and
Consultant is willing to provide such services in accordance with the terms
and conditions set forth below,

     NOW, THEREFORE, in consideration of the mutual covenants and undertakings
herein contained, the parties hereto agree to establish such client/consultant
relationship in accordance with the following terms and conditions set forth
below:

ABTG in accordance with the terms and conditions hereof (the "Services"), which
shall include, but not necessarily be limited to, the following:

by the mutual agreement of ABTG and the Consultant, to increase the visibility
and corporate profile of ABTG to the financial community and the public at
large;

        (ii) assisting brokers, financial professionals, investors and other
interested persons in obtaining current information about ABTG's operations,

<PAGE>


     1.2 The Consultant shall be obligated to render the services upon the
request of ABTG, in good faith, but shall not be obligated to expend any
specified amount of time in so doing. Consultant may work according to its own
methods and keep its own hours; ABTG shall not control the manner in which
Consultant works while performing under this Agreement. Notwithstanding the
foregoing, inasmuch as the Board of Directors of ABTG has retained the
Consultant to provide significant services and has a duty to the stockholders of
ABTG to supervise the operations of ABTG; Consultant accordingly agrees to
report to and be promptly responsive to redirection, questions, concerns, or
comments raised by the Board regarding the Services.

     1.3 Consultant shall be responsible for the payment of all fees and
expenses of the firm retained pursuant to Section 1.1 hereof, and any persons
Consultant procures to assist it in performance of the Services. Any such
assistants shall be compensated by Consultant and are deemed employees solely of
Consultant. Consultant agrees to be solely responsible for any actions of its
assistant, agents or other employees. Consultant agrees to comply with all
applicable Federal, state and local laws, regulations and ordinances.
Notwithstanding the foregoing, ABTG agrees to provide Consultant with support
and cooperation in connection with the performance of the Services.

     1.4 ABTG recognizes and confirms that, in advising ABTG and in fulfilling
its responsibilities under this agreement, the Consultant will use and rely on
data, material and other information furnished to the Consultant by ABTG. ABTG
acknowledges and agrees that in performing the Services under this Agreement,
the Consultant may rely upon data, material and other information supplied by
ABTG without independently verifying the accuracy, completeness or veracity of
the same. Accordingly, ABTG expressly agrees that all data, material and other
information furnished to the Consultant by ABTG shall not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

2. PAYMENT FOR SERVICES

     2.1 As full compensation for the performance of the Services ABTG shall:

        (i) issue to Consultant a nonqualified stock option (the "Option") under

and other terms, conditions and provisions as shall be determined by ABTG, and
shall be in the form of Exhibit A hereto;

        (ii) issue to Consultant an aggregate of 65,000 shares of Common Stock

Consultant. Consultant shall be solely responsible for the payment of any and
all Federal, state, and local income taxes, Social Security taxes and
unemployment taxes that may be generated hereunder. ABTG shall not withhold any
such items and bears no responsibility for any such payments. The Consultant
shall perform the Services hereunder as an independent contractor and not as an
employee of ABTG or an affiliate thereof. It is expressly understood and agreed
to by the parties hereto that the Consultant shall not have authority to act
for, represent or bind ABTG or any affiliate thereof in any manner.

     2.3 ABTG shall use its best efforts to: (i) include each Tranche of
Compensation Shares issued to Consultant in a registration statement of ABTG on
Form S-8 or other qualifying or successor form to be filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933 (the
"1933 Act"); and (ii) have such registration statement declared effective by the

is issued.
