         THIS AGREEMENT is made and entered into as of this 18th day of March,
1992, by and between ROBERT WILSON ("Mr. Wilson") and RADIO METRIX INC.
("RMI").

                                  WITNESSETH:

         WHEREAS, Arvin Brent Simon has developed technology for a sensing
device utilizing radio waves in a unique fashion (herein the "TECHNOLOGY"); and

         WHEREAS, Arvin Brent Simon, together with David Jones, Scott
Morneweck, Roger Keith and Thomas Cudnik (herein "RMC") have assigned all
rights to said TECHNOLOGY to SDR Metro, Inc., a corporation organized by them to
develop the TECHNOLOGY; and

         WHEREAS, SDR Metro, Inc. has entered into an exclusive, worldwide,
perpetual License Agreement with RMI concerning all applications of the
TECHNOLOGY; and

         WHEREAS, Mr. Wilson previously entered into an agreement with RMC, an
unincorporated entity doing business for the benefit of David Jones, Scott
Morneweck, Roger Keith, Thomas Cudnik, and Arvin Brent Simon (herein
collectively referred to as "RMC"), providing Mr. Wilson with certain marketing
rights, as specified in Exhibit "A" hereto; and

         WHEREAS, Exhibit "A" and the marketing rights granted to Mr. Wilson
thereunder were subsequently terminated by RMC pursuant to Exhibit "B"; and

         WHEREAS, Mr. Wilson attempted to assign part or all of his rights
under Exhibit "A" to Magnetic Maulburg, a German corporation, pursuant to
Exhibit "C"; and

         WHEREAS, Mr. Wilson introduced RMI, or its principals, Mr. Stephen
Michael and Mr. Samuel Duffey, to RMC for the purposes of attempting to
establish a commercialization agreement concerning the TECHNOLOGY; and

         WHEREAS, RMI had previously invited Mr. Wilson to be a participant and
stockholder of RMI as compensation for Mr. Wilson's introduction and
anticipated ongoing efforts to participate in the commercialization of the
TECHNOLOGY; and

         WHEREAS, RMI has withdrawn its invitation to Mr. Wilson to serve as a
participant or stockholder in RMI upon learning the correct facts and
circumstances surrounding Mr. Wilson's business and contractual relationships
with both RMC and Magnetic Maulburg; and



<PAGE>
         WHEREAS, RMI wishes to grant Mr. Wilson a royalty interest in future
potential revenues of RMI resulting solely from the TECHNOLOGY as sole and
exclusive compensation to Mr. Wilson for his introduction of RMI to RMC and any
prior or future assistance which he may provide in the commercialization of
TECHNOLOGY; and

         WHEREAS, RMI and Mr. Wilson wish to enter into this Agreement as the
definitive and exclusive statement of their understanding and agreement.

         NOW, THEREFORE, for good and valuable consideration, in hand received,
the parties hereto mutually agree as follows:

         1.       Compensation. RMI hereby agrees to pay to Mr. Wilson as Mr.
Wilson's sole and exclusive compensation from RMI and its stockholders and
principals an amount equal to five percent (5%) of the royalty revenue received
by RMI from the TECHNOLOGY, less any amounts paid or required to be paid to RMC
or SDR Metro, Inc. for the licensing rights to said TECHNOLOGY. In the event
RMI becomes the manufacturer or marketer of products incorporating the
TECHNOLOGY, RMI shall, in lieu of the foregoing compensation, pay Mr. Wilson
compensation equal to five percent (5%) of the adjusted gross revenues of RMI
from such sales, which involve the manufacture or marketing of products by RMI.
"Adjusted Gross Revenue" shall mean gross revenues from the sale of products
manufactured or marketed by RMI and incorporating the TECHNOLOGY, less all
costs of manufacturing, licensing, fees and royalties, manufacturing,
advertising, and cost of sales. The compensation provided for herein shall
continue for the life of the license arrangement between RMI and SDR Metro,
Inc. concerning the TECHNOLOGY. The Compensation provided for in this Agreement
is related solely and exclusively to the TECHNOLOGY described in the Agreement
dated March 14, 1992 between RMI and SDR Metro, Inc. In the event of revenues
earned by RMI for development purposes or for signing license arrangements, but
which do not constitute advance royalty fees, no compensation shall be paid to
Mr. Wilson hereunder. Should RMI receive compensation from the sale of the
TECHNOLOGY or a license fee that does not require ongoing royalty fees, RMI
shall pay Mr. Wilson an amount equal to 5% of RMI's net proceeds. For purposes
hereof, "net proceeds" shall mean gross proceeds less costs of procuring and
closing the sale or license, and royalty or other fees to be paid to SDR Metro,
Inc.

         2.       Buy-Out. Mr. Wilson agrees that the compensation arrangement
may be purchased by RMI or its assigns at any time for an aggregate purchase
price not to exceed $200,000, with all royalties earned during the first 24
months of this Agreement, constituting being credited against the purchase
price.

         3.       No Claim. Mr. Wilson expressly acknowledges and agrees that
he has no right, claim, or interest in or to the TECHNOLOGY. Furthermore, Mr.
Wilson acknowledges and agrees that he has no right, title, or interest in or
to, or any claim against, RMI or


                                       2
<PAGE>
any of its principals, save and except only his right to compensation as set
forth in paragraph 1 of this Agreement. Mr. Wilson acknowledges and agrees that
the Marketing Agreement designated Exhibit "A" hereto is void and of no
continuing effect and that he has no marketing rights or other interest in or
to the TECHNOLOGY arising thereunder. Simultaneously with the execution of this
Agreement, Mr. Wilson agrees to execute the General Release attached hereto as
Exhibit "D".

         4.       Proper Conduct. Mr. Wilson acknowledges and agrees that the
conduct of Duffey & Davis, P.A., and Attorney Samuel S. Duffey have been
appropriate and ethical at all times in connection with this transaction. Mr.
Wilson acknowledges that the purpose of this paragraph is to verify and confirm
that this Agreement is viewed by Mr. Wilson as consistent with the legal
responsibility of Duffey & Davis, P.A., and Mr. Duffey and does not in any
fashion constitute a conflict of interest or conduct which is viewed by Mr.
Wilson as unethical. Mr. Wilson acknowledges that he has been advised to
consult with and rely upon the advice of independent legal counsel and,
further, Mr. Wilson acknowledges and agrees that he has not relied upon the
advice of Mr. Duffey or Duffey & Davis, P.A., concerning this Agreement or
matters relating to RMC, RMI, or the TECHNOLOGY. Mr. Wilson acknowledges that,
while he consulted with Mr. Duffey concerning RMC and the TECHNOLOGY, his
marketing agreement was subsequently terminated by RMC, and he subsequently
requested of his own volition and with no suggestion from Mr. Duffey that Mr.
Duffey and Mr. Michael take over the project of attempting to commercialize the
TECHNOLOGY for their own interests and not in an attorney/client or other
confidential relationship with Mr. Wilson. Mr. Wilson acknowledges and agrees
that should any contention that Mr. Duffey or Duffey & Davis, P.A., acted other
than in a proper, correct, and ethical manner be made in the future by Mr.
Wilson, such contention would be for the sole purpose and intent of slandering
or adversely affecting the reputation of Mr. Duffey and would be actionable as
an intentional wrongdoing on the part of Mr. Wilson. Mr. Wilson acknowledges
and agrees that this paragraph 4 is a material inducement for RMI to enter into
this Agreement.

         5.       Confidentiality. Mr. Wilson acknowledges and agrees that any
and all information that he holds concerning the TECHNOLOGY is confidential and
cannot be disclosed by him to any third party without the prior permission or
approval of RMI. In furtherance of this confidentiality provision and not in
limitation thereof, Mr. Wilson shall execute, simultaneously with the execution
of this Agreement, the Confidentiality Agreement attached hereto as Exhibit
"E".

         6.       Covenant Not to Compete. Mr. Wilson agrees that during the
term of this Agreement and for a period of five years thereafter, he shall not,
either directly or indirectly, engage in any activity which is competitive with
the TECHNOLOGY licensed by


                                       3
<PAGE>
RMI from SDR Metro, Inc. For purposes hereof, activities competitive with the
TECHNOLOGY shall include, but not be limited to, any development, design,
marketing, commercialization, or manufacture of any product or any technology
which has a use or function similar to that served by the TECHNOLOGY, or which
may be served by the TECHNOLOGY during the term of this Agreement ("Competitive
Activity"). Indirectly engaging in any Competitive Activity shall include, but
not be limited to, serving as an officer, director, owner, partner,
shareholder, or agent or employee of any entity engaged in any Competitive
Activity.

         7.       Beneficial Party. Each of the agreements, covenants, and
representations of Mr. Wilson contained in this Agreement or any exhibit hereto
shall inure to the benefit of and shall be enforceable by SDR Metro, Inc., as
well as RMI and its principals.

         8.       Miscellaneous. This Agreement constitutes the entire
understanding of the parties and shall not be amended or otherwise altered,
except in writing and executed by the parties hereto. This Agreement shall be
governed by and construed in accordance with the laws of the state of Florida.
This Agreement shall not be construed more stringently against any party,
regardless of who may have been the draftsman. Any dispute arising under this
Agreement or any of the exhibits attached to this Agreement shall be resolved
by binding arbitration before the American Arbitration Association. Arbitration
shall be the sole and exclusive method for resolving any dispute or enforcing
this Agreement, and arbitration shall be seated solely in Sarasota, Florida,
and shall be before the American Arbitration Association. The findings of
arbitrators shall be final and binding and may be reduced to a judgment in any
court of competent jurisdiction.

         IN WITNESS WHEREOF, the parties hereto set their hands and seals on
the day and year first above written.

Dear Mr. Wilson:

Since, you have ceased all communications with us, and refuse to to return our
phone messages we assume the following:

         1.       You are unable to secure financing to our August 1991
                  Business Plan.

         2.       You are no longer interested in fulfilling your obligations
                  under our agreement entered into on August 24th, 1991 by and
                  between Robert A. Wilson and RADIO METRIX COMPANY (RMC).

RMC sees no alternative but to terminate its agreement with you, due to lack of
funds, within seven (7) days from the writing of this letter. Termination of
our agreement is based on your non-performance of duties (Article II) paragraph
(A) subparagraph (b) "Wilson shall arrange financing for the Corporation.....".
Our agreement will be considered null and void under (Article XIII Item 2) "If
Wilson fails to perform reasonable marketing expectations outlined in the
business plan".

registered mail.


Sincerely,

Mr. Robert Wilson
1516 South Orange Avenue
Sarasota, FL 34239


Dear Mr. Wilson:

         For almost seven years, Radio Metrix, Inc. has neither received
contact from you nor been advised by you with regard to contact information or
your current location. Both Sam and I are disappointed that you have elected to
abandon Radio Metrix, Inc. and your responsibilities under the Agreement. Your
decision to make yourself unavailable on a long-term basis and to provide no
assistance or support to Radio Metrix, Inc., as required under the Agreement,
constitutes a material breach of the Agreement entered into on March 18, 1992
between you and Radio Metrix, Inc. The purpose of this correspondence is to
exercise one last effort to provide you with formal notice that Radio Metrix,
Inc. considers the Agreement with you to be terminated by virtue of your
breach. You are further notified that Radio Metrix, Inc. intends to have no
ongoing or continuing relationship with you. In the event that you disagree
with the Company's position, we invite you to participate in an arbitration
proceeding in Sarasota, Florida as designated in the Agreement.


Very truly yours,
RADIO METRIX, INC.


/s/ Stephen A. Michael, President
