ATTN: WILBERT MYLES

Dear Mr. Myles:

         Reference is made to that certain Securities Purchase Agreement, of
even date herewith, by and among BioShield Technologies, Inc., a Georgia
corporation (the "COMPANY"), and each of the subscribers listed in Exhibit "A"
attached hereto (collectively, the "HOLDERS") pursuant to which the Company is
issuing to the Holders an aggregate of 200 shares of Series B Preferred Stock,
no par value, of the Company (the "PREFERRED SHARES"). This letter shall serve
as our irrevocable authorization and direction to you (provided that you are the
transfer agent of the Company at such time) to issue shares (the "CONVERSION
SHARES") of Common Stock, no par value (the "COMMON STOCK"), of the Company to
or upon the order of a Holder from time to time upon (i) surrender to you of a
properly completed and duly executed Conversion Notice, in the form attached
hereto as Exhibit I, which has been properly agreed and acknowledged by the
Company as indicated by the signature of a duly authorized officer of the
Company thereon and (ii) certificates representing Preferred Shares being
converted (or an indemnification undertaking with respect to such shares in the
case of their loss, theft or destruction). So long as you have previously
received: (i) written confirmation from counsel to the Company that a
registration statement covering resales of the Conversion Shares has been
declared effective by the U.S. Securities and Exchange Commission (the "SEC")
under the Securities Act of 1933, as amended (the "1933 ACT"), and (ii) a copy
of such Registration Statement, Certificates representing the Conversion Shares
shall not bear any legend restricting transfer of the Conversion Shares thereby
and should not be subject to any stop-transfer restriction. However, if you have
not previously received (i) written confirmation from counsel to the Company
that a registration statement covering resales of the Conversion Shares has been
declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended, and (ii) a copy of such registration
statement, then the certificates representing the Conversion Shares shall bear
the following legend:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE
         STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT
         AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
         ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
         THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
<PAGE>   2
         SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN A REASONABLY ACCEPTABLE
         FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE
         STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID
         ACT."

provided, however, that the Company may from time to time notify you to place
stop transfer restrictions on the certificates for the Conversion Shares in the
event a registration statement covering the Conversion Shares is subject to
amendment for events then current.

         An opinion of counsel to the Company that the issuance of the
Conversion Shares to the Holders will be exempt from registration under the 1933
Act is attached hereto as Exhibit II.

         Please be advised that the Holders are relying upon this letter as an
inducement to enter into the Securities Purchase Agreement and, accordingly,
each Holder is a third party beneficiary to these instructions.

         Should you have any questions concerning this matter please contact me
at (770) 326-9890.

                                       Very truly yours,

                                       BIOSHIELD TECHNOLOGIES, INC.
