                                   EXHIBIT A

                         Notice of Exercise of Option

     Under a certain Option Agreement dated as of November 30, 2001 (the "Option
Agreement"), the undersigned RDS Tasks of Ohio, Inc., an Ohio corporation
("RDS") has been granted an Option to purchase from Christine Bachmann
("Bachmann" and/or "Optionor") up to 7.5 Million Shares of Common Stock at
______ Cents ($0.___) Exercise Price per share (the "Shares"), of GeoAlert
Incorporated ("GeoAlert") subject to the terms and conditions of the Option
Agreement. Capitalized terms that are used but that are not otherwise defined in
this Notice shall have the same meanings herein as ascribed in the Option
Agreement.

     In order to induce Bachmann and GeoAlert to sell and issue the Shares to
RDS, RDS hereby notifies, represents and warrants to and agrees with Bachmann
and GeoAlert as follows:

     1.   Notice of Exercise. RDS elects to exercise the Option and purchase
_______________ of the total of ______________ Shares that it is entitled to
purchase under the Option Agreement. At the same time that RDS is delivering
this Notice to Bachmann and GeoAlert, RDS will also deliver to Bachmann a
certified or bank cashier's check in the amount of $______________, which is the
full amount of the Option Price payable by RDS for the Shares being purchased,
payable to the order of "Christine Bachmann". RDS is delivering this Notice and
the foregoing payment to Bachmann and to GeoAlert.

     2.   Restricted Securities. RDS understands and acknowledges that none of
the Shares will be registered or qualified under the Securities Act of 1933, as
amended, and the rules of and regulations thereunder (the "Act"), or under any
state securities laws, in reliance upon specific exemptions thereunder for
transactions not involving any public offering, and may not be sold, transferred
or otherwise disposed of unless a registration statement under the Act and
qualification in accordance with any applicable state securities laws with
respect to such Shares has become effective, or unless it is established to the
satisfaction of GeoAlert that an exemption from such registration and
qualification is available. RDS understands and agrees that all certificates
representing the Shares will bear a restrictive legend concerning the foregoing
restrictions on transferability; that no market presently exists for the Shares,
and there can be no assurance that any such market will develop, and that RDS
may be required to bear the economic risk of its investment in the Shares for an
indefinite period of time.

     3.   Representations and Warranties. RDS represents and warrants to
Bachmann and GeoAlert that:

     (a)  RDS is acquiring the Shares solely for its own account, for investment
          purposes only, and not with a view to, or with any present intention
          of, any resale or distribution of the Shares or any part thereof or to
          divide its participation with others, and no person other than RDS has
          any interest in or right to the Shares.

     (b)  RDS has sufficient knowledge and experience in financial and business
          matters in general and its is capable of evaluating the merits and
          risks of an investment in the Shares.

     (c)  RDS has been informed and understands that the investment in the
          Shares is a speculative investment and involves a high degree of risk,
          and that the amount realized on such
<PAGE>

          investment may be less than the amount invested. In evaluating its
          investment in the Shares, RDS has consulted with its own investment,
          legal and tax advisors and has concluded that such investment is not
          inconsistent with, and is appropriate in light of its overall
          investment objectives, financial condition and liquidity requirements.
          RDS is familiar with the nature of and risks inherent to an investment
          of the type contemplated hereby, the tax aspects of an investment of
          such type and is financially and otherwise capable of bearing the
          economic risk of such an investment and can afford the loss of the
          total amount of such investment.

     (d)  RDS understands and acknowledges that (i) the Shares have not been
          registered under the provisions of the Act or any state securities
          laws in reliance upon specific exemptions thereunder for transactions
          not involving any public offering, and the availability of such
          exemptions depends in part upon the accuracy of its representations
          and warranties herein, (ii) the Act and applicable state securities
          laws impose substantial restrictions on the transferability of the
          Shares, (iii) no market presently exists for the Shares and there can
          be no assurance that any such market will develop, and (iv) RDS may be
          unable to liquidate its investment in the Shares and, as a result, may
          have to hold the Shares and bear the economic risk of its investment
          for an indefinite period of time.

     In Witness Whereof, the undersigned has executed and delivered this Notice
of Option to Exercise to Christine Bachmann and to GeoAlert Incorporated on the
date set forth below.
