                                   EXHIBIT A

                         NOTICE OF EXERCISE OF OPTION

Nevada corporation ("GeoAlert"), a certain number of Common Shares at _____
Cents ($0.__) Exercise Price per share (the "Shares"), of GeoAlert Incorporated
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 GeoAlert to sell and issue the Shares to RDS, RDS hereby
notifies, represents and warrants to and agrees with 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 GeoAlert, RDS will also deliver to GeoAlert 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
"GeoAlert Incorporated".  RDS is delivering this Notice and the foregoing
payment 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
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 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
<PAGE>

           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 GeoAlert Incorporated on the date set forth below.
