ATTENTION:  COMPLIANCE DEPARTMENT

Dear Sir or Madam:

         Reference is made to the Private Equity Credit Agreement (the
"Agreement"), dated as of June 14, 2000, between Jackson LLC (the "Investor")
and BioShield Technologies, Inc. (the "Company"). Pursuant to the Agreement,
subject to the terms and conditions set forth in the Agreement the Investor has
agreed to purchase from the Company and the Company has agreed to sell to the
Investor from time to time during the term of the Agreement shares of common
stock of the Company, no par value per share (the "Common Stock"). As a
condition to the effectiveness of the Agreement, the Company has agreed to issue
to you, as the transfer agent for the Common Stock (the "Transfer Agent"), these
instructions relating to the Common Stock to be issued to the Investor (or a
permitted assignee) pursuant to the Agreement. All terms used herein and not
otherwise defined shall have the meaning set forth in the Agreement.

         1.       ISSUANCE OF COMMON STOCK WITHOUT THE LEGEND.

         Pursuant to the Agreement, the Company is required to prepare and file
with the Commission, and maintain the effectiveness of, a registration statement
or registration statements registering the resale of the Common Stock to be
acquired by the Investor under the Agreement. The Company will advise the
Transfer Agent in writing of the effectiveness of any such registration
statement promptly upon its being declared effective. The Transfer Agent shall
be entitled to rely on such advice and shall assume that the effectiveness of
such registration statement remains in effect unless the Transfer Agent is
otherwise advised in writing by the Company and shall not be required to
independently confirm the continued effectiveness of such registration
statement. In the circumstances set forth in the following paragraph, the
Transfer Agent shall deliver to the delivering broker certificates representing
Common Stock not bearing the Legend without requiring further advice or
instruction or additional documentation from the Company or its counsel or the
Investor or its counsel or any other party (other than as described in such
paragraph).

         At any time after the effective date of the applicable registration
statement (provided that the Company has not informed the Transfer Agent in
writing that such registration statement is not then effective), upon any
surrender of one or more certificates evidencing Common Stock which bear the
Legend, to the extent accompanied by a notice requesting the issuance of new
certificates free of the Legend to replace those surrendered, the Transfer Agent
shall deliver to the delivering broker the certificates representing the Common
Stock not bearing the Legend, in

such names and denominations as such broker shall request, provided that, in
connection with such event, the delivering broker (or its permitted assignee)
shall confirm in writing to the Transfer Agent and the Company that (i) the
Investor has sold, pledged or otherwise transferred or agreed to sell, pledge or
otherwise transfer such Common Stock in a bona fide transaction to a designated
transferee that is not an affiliate of the Company; and (ii) the delivering
broker has complied with the prospectus delivery requirements under the
Securities Act of 1933, as amended.

         Any advice, notice or instructions to the Transfer Agent required or
permitted to be given hereunder may be transmitted via facsimile to the Transfer
Agent's facsimile number of (718) 921-8248.

         2.       MECHANICS OF DELIVERY OF CERTIFICATES REPRESENTING COMMON
                  STOCK.

         In connection with any Closing pursuant to which the Investor acquires
Common Stock under the Agreement, the Transfer Agent shall deliver certificates
representing Common Stock (with or without the Legend, as appropriate) as
promptly as practicable, but in no event later than three business days, after
such Closing.

         3.       FEES OF TRANSFER AGENT; INDEMNIFICATION.

         The Company agrees to pay the Transfer Agent for all fees incurred in
connection with these Irrevocable Instructions. The Company agrees to indemnify
the Transfer Agent and its officers, employees and agents, against any losses,
claims, damages or liabilities, joint or several, to which it or they become
subject based upon the performance by the Transfer Agent of its duties in
accordance with the Irrevocable Instructions.

         4.       THIRD PARTY BENEFICIARY.

         The Company and the Transfer Agent acknowledge and agree that the
Investor is an express third party beneficiary of these Irrevocable Instructions
and shall be entitled to rely upon, and enforce, the provisions hereof.

                                WARRANT AGREEMENT

         WARRANT AGREEMENT dated as of June 14, 2000, between BioShield
Technologies, Inc., a Delaware corporation (the "COMPANY"), and Jackson LLC, a
Cayman Island limited liability company (hereinafter referred to as "INVESTOR").

                           W I T N E S S E T H:

         WHEREAS, Investor has entered into a Private Equity Agreement (the
"INVESTMENT AGREEMENT') with the Company pursuant to which the Investor may
purchase up to $50,000,000 of shares of common stock, no par value, of the
Company (the "COMMON STOCK"); and

         WHEREAS, the Warrants issued pursuant to this Agreement are being
issued by the Company to Investor and/or its designees, in consideration for,
and as part of the investment by Investor in connection with the Investment
Agreement;

                  NOW, THEREFORE, in consideration of the premises, the
agreements herein set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows (capitalized terms used herein without definition shall have
the meanings ascribed to then in the Investment Agreement):

         1.       Grant.

         Investor and/or its designees are hereby granted the right to purchase,
at any time from the date of the closing of the first purchase by Investor of
shares of Common Stock pursuant to the Investment Agreement (the "INITIAL
CLOSING") until 5:00 P.M., Eastern Standard Time, on the fifth anniversary of
the Initial Closing (the "WARRANT EXERCISE TERM"), 250,000 Shares of Common
Stock (the "SHARES") at an exercise price (subject to adjustment as provided in
Article 7 hereof) equal to $18.92 (the "INITIAL EXERCISE PRICE").

         2.       Warrant Certificates.

         The warrant certificates (the"WARRANT CERTIFICATES") delivered and to
be delivered pursuant to this Agreement shall be in the form set forth as
Exhibit A, attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as required or
permitted by this Agreement.

         3.       Exercise of Warrants.

                                      -1-
<PAGE>   2

                  3.1      Cash Exercise. The Exercise Price may be paid in cash
or by check to the order of the Company, or any combination of cash or check,
subject to adjustment as provided in Article 7 hereof. Upon surrender of the
Warrant Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Exercise Price (as hereinafter defined) for the
Shares purchased, at the Company's executive offices currently located at 5655
Peachtree Parkway Atlanta, Georgia 30092, the registered holder of a Warrant
Certificate ("HOLDER" or "HOLDERS") shall be entitled to receive a certificate
or certificates for the Shares so purchased. The purchase rights represented by
each Warrant Certificate are exercisable at the option of the Holder hereof, in
whole or in part (but not as to fractional shares of the Common Stock). In the
case of the purchase of less than all the Shares purchasable under any Warrant
Certificate, the Company shall cancel said Warrant Certificate upon the
surrender thereof and shall execute and deliver a new Warrant Certificate of
like tenor for the balance of the Shares purchasable thereunder.

                  3.2      Cashless Exercise. At any time during the Warrant
Exercise Term, the Holder may, at its option, exchange this Warrant, in whole or
in part (a "WARRANT EXCHANGE"), into the number of Shares determined in
accordance with this Section 3.2, by surrendering this Warrant at the principal
office of the company or at the office of its transfer agent, accompanied by a
notice stating such Holder's intent to effect such exchange, the number of
Shares to be exchanged and the date on which the Holder requests that such
Warrant Exchange occur (the "NOTICE OF EXCHANGE"). The Warrant Exchange shall
take place on the date specified in the Notice of Exchange or, if later, the
date the Notice of Exchange is received by the Company (the "EXCHANGE Date").
Certificates for the Shares issuable upon such Warrant Exchange and, if
applicable, a new warrant of like tenor evidencing the balance of the Shares
remaining subject to this Warrant, shall be issued as of the Exchange Date and
delivered to the Holder within seven (7) business days following the Exchange
Date. In connection with any Warrant Exchange, this Warrant shall represent the
right to subscribe for and acquire the number of Shares (rounded to the next
highest integer) equal to (i) the number of Shares specified by the Holder in
its Notice of Exchange (the "TOTAL NUMBER") less (ii) the number of Shares equal
to the quotient obtained by dividing (A) the product of the Total Number and the
then existing Exercise Price by (B) the average of the Closing Prices for the
five Trading Days immediately prior to the date specified in the Notice of
Exchange.

                  3.3      Exercise Limitation. In no event shall any Investor
be entitled to exercise any of the warrants if, upon the exercise of such
warrant(s), it would cause the aggregate number of shares of Common Stock
beneficially owned by the Investor and its affiliates to exceed 4.9% of the
outstanding shares of the Common Stock following such exercise.

         4.       Issuance of Certificates.

         Upon the exercise of the Warrants, the issuance of certificates for the
Shares shall be made forthwith (and in any event within five business days
thereafter) without charge to the

                                      -2-
<PAGE>   3

Holder thereof including, without limitation, any tax which may be payable in
respect of the issuance thereof, and such certificates shall be issued in the
name of, or in such names as may be directed by, the Holder thereof; provided,
however, that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificates in a name other than that of the Holder and the Company shall
not be required to issue or deliver such certificates unless or until the person
or persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to satisfaction of the Company that
such tax has been paid.

         The Warrant Certificates and the certificates representing the Shares
shall be executed on behalf of the Company by the manual or facsimile signature
of the present or any future Chairman or Vice Chairman of the Board of
Directors, Chief Executive officer or President or Vice President of the Company
under its corporate seal reproduced thereon, attested to by the manual or
facsimile signature of the present or any future Secretary or Assistant
Secretary of the Company. Warrant Certificates shall be dated the date of
execution by the Company upon initial issuance, division, exchange, substitution
or transfer.

         The Warrant Certificates and, upon exercise of the Warrants, in part or
in whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended (the "ACT"), and may not
         be offered or sold except (i) pursuant to an effective registration
         statement under the Act, (ii) to the extent applicable, pursuant to
         Rule 144 under the Act (or any similar rule under such Act relating to
         the disposition of securities), or (iii) upon the delivery by the
         holder to the Company of an opinion of counsel, satisfactory to counsel
         to the issuer, stating that an exemption from registration under such
         Act is available.

         5.       Price.

                  5.1      Adjusted Exercise Price. The adjusted Exercise Price
shall be the price which shall result from time to time from any and all
adjustments of the Initial Exercise Price in accordance with the provisions of
Article 7 hereof.

                  5.2      Exercise Price. The term "EXERCISE PRICE" herein
shall mean the Initial Exercise Price or the adjusted Exercise Price, depending
upon the context.

         6.       Registration Rights.

                  6.1      Registration Under the Securities Act of 1993.

                                      -3-
<PAGE>   4

                  The Warrants and the Shares have not been registered for
purposes of public distribution under the Securities Act of 1933, as amended
("THE ACT").

                  6.2      Registrable Securities. As used herein the term
"REGISTRABLE SECURITY" means each of the Warrants, the Shares and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
Shares; provided, however, that with respect to any particular Registrable
Security, such security shall cease to be a Registrable Security when, as of the
date of determination, (i) it has been effectively registered under the
Securities Act and disposed of pursuant thereto, (ii) registration under the
Securities Act is no longer required for the immediate public distribution of
such security or (iii) it has ceased to be outstanding. The term "REGISTRABLE
SECURITIES" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security." In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Article 6.

                  6.3      Piggyback Registration. If, at any time during the
five years following the date of the Initial Closing, the Company proposes to
prepare and file any registration statement or post-effective amendments (other
than in connection with an underwritten initial public offering or initial
registration of the Company or the Company=s securities with the U.S. Securities
& Exchange Commission) thereto covering equity or debt securities of the
Company, or any such securities of the Company held by its shareholders (in any
such case, other than in connection with a merger, acquisition or pursuant to
Form S-8 or successor form), (for purposes of this Article 6, collectively, a
"REGISTRATION STATEMENT"), it will give written notice of its intention to do so
by registered mail ("NOTICE"), at ten (10) business days prior to the filing of
each such Registration Statement, to all holders of the Registrable Securities.
Upon the written request of such a holder (a "REQUESTING HOLDER"), made within
ten (10) business days after receipt of the Notice, that the Company include any
of the Requesting Holder's Registrable Securities in the proposed Registration
Statement, the Company shall, as to each such Requesting Holder, use its best
efforts to effect the registration under the Securities Act of the Registrable
Securities which it has been so requested to register ("PIGGYBACK
REGISTRATION"), at the Company's sole cost and expense and at no cost or expense
to the Requesting Holders. Notwithstanding the provisions of this Section 6.3,
the Company shall have the right at any time after it shall have given written
notice pursuant to this Section 6.3 (irrespective of whether any written request
for inclusion of such securities shall have already been made) to elect not to
file any such proposed Registration Statement, or to withdraw the same after the
filing but prior to the effective date thereof.

         7.       Adjustments of Exercise Price and Number of Shares.

                  7.1      Subdivision and Combination. In case the Company
shall at any time subdivide or combine the outstanding shares of Common Stock,
the Exercise Price shall

                                      -4-
<PAGE>   5

forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination.

                  7.2      Adjustment in Number of Shares. Upon each adjustment
of the Exercise Price pursuant to the provisions of this Article 7, the number
of Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of Shares issuable upon
exercise of the Warrants immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

                  7.3      Reclassification, Consolidation, Merger, etc. In case
of any reclassification or change of the outstanding shares of Common Stock
(other than a change in par value to no par value, or from no par value to par
value, or as a result of a subdivision or combination), or in the case of any
consolidation of the Company with, or merger of the Company into, another
corporation (other than a consolidation or merger in which the Company is the
surviving corporation and which does not result in any reclassification or
change of the outstanding shares of Common Stock, except a change as a result of
a subdivision or combination of such shares or a change in par value, as
aforesaid), or in the case of a sale or conveyance to another corporation of the
property of the Company as an entirety, the Holders shall thereafter have the
right to purchase the kind and number of shares of stock and other securities
and property receivable upon such reclassification, change, consolidation,
merger, sale or conveyance as if the Holders were the owners of the shares of
Common Stock underlying the Warrants immediately prior to any such events at a
price equal to the product of (x) the number of shares issuable upon exercise of
the Warrants and (y) the Exercise Price in effect immediately prior to the
record date for such reclassification, change, consolidation, merger, sale or
conveyance as if such Holders had exercised the Warrants.

                  7.4      No Adjustment of Exercise Price in Certain Cases. No
adjustment of the Exercise Price shall be made:

                           (a)      Upon the issuance or sale of shares of
                  Common Stock upon the exercise of the Warrants; or

                           (b)      Upon (i) the issuance of options pursuant to
                  the Company's employee stock option plans in effect or the
                  issuance or sale by the Company of any shares of Common Stock
                  pursuant to the exercise of any such options, or (ii) the
                  issuance or sale by the Company of any shares of Common Stock
                  pursuant to the exercise of any options or warrants; or

                           (c)      Upon the issuance of shares of Common Stock
                  pursuant to contractual obligations; or

                                      -5-
<PAGE>   6

                           (d)      If the amount of said adjustment shall be
                  less than 2 cents (24) per Share, provided, however, that in
                  such case any adjustment that would otherwise be required then
                  to be made shall be carried forward and shall be made at the
                  time of and together with the next subsequent adjustment
                  which, together with any adjustment so carried forward, shall
                  amount to at least 2 cents (24) per Share.

         8.       Exchange and Replacement of Warrant Certificates.

         Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

         9.       Elimination of Fractional Interests.

         The Company shall not be required to issue certificates representing
fractions of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

         10.      Reservation and Listing of Securities.

         The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock issuable upon such exercise shall be duly and validly issued,
fully paid, nonassessable and not subject to the preemptive rights of any
shareholder. As long as the Warrants shall be outstanding, the Company shall use
its best efforts, once it has become a public company, to cause all shares of
Common Stock issuable upon the exercise of the Warrants to be listed on or
quoted on the electronic bulletin board, by NASDAQ or listed on such national
securities exchanges.

         11.      Notices to Warrant Holders.

                                      -6-
<PAGE>   7

         Nothing contained in this Agreement shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive notice
as a shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

                  (a)      the Company shall take a record of the holders of its
         shares of Common Stock for the purpose of entitling them to receive a
         dividend or distribution payable otherwise than in cash, or a cash
         dividend or distribution payable otherwise than out of current or
         retained earnings, as indicated by the accounting treatment of such
         dividend or distribution on the books of the Company; or

                  (b)      a dissolution, liquidation or winding up of the
         Company (other than in connection with a consolidation or merger) or a
         sale of all or substantially all of its property, assets and business
         as an entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale. Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be. Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or any proposed dissolution,
liquidation, winding up or sale .

         12.      Notices.

         All notices, requests, consents and other communications hereunder
shall be in writing and shall be deemed to have been duly made when delivered,
or mailed by registered or certified mail, return receipt requested:

                  (a)      If to a registered Holder of the Warrants, to the
         address of such Holder as shown on the books of the Company; or

                  (b)      If to the Company, to the address set forth in
         Section 3 of this Agreement or to such other address as the Company may
         designate by notice to the Holders.

         13.      Supplements and Amendments.

                                      -7-
<PAGE>   8

         The Company may from time to time supplement or amend this Agreement
without the approval of any Holders of Warrant Certificates in order to cure any
ambiguity, to correct or supplement any provision contained herein which may be
defective or inconsistent with any provisions herein, or to make any other
provisions in regard to matters or questions arising hereunder which the Company
may deem necessary or desirable and which the Company deems not to adversely
affect the interests of the Holders of Warrant Certificates.

         14.      Successors.

         All the covenants and provisions of this Agreement by or for the
benefit of the Company and the Holders inure to the benefit of their respective
successors and assigns hereunder.

         15.      Termination.

         This Agreement shall terminate at the close of business on the fifth
anniversary of the Initial Closing. Notwithstanding the foregoing, this
Agreement will terminate on any earlier date when all Warrants have been
exercised and all the Shares issuable upon exercise of the Warrants have been
resold to the public; provided, however, that the provisions of Article 6 shall
survive such termination until the close of business on fifth anniversary of the
Initial Closing.

         16.      Governing Law.

         This Agreement and each Warrant Certificate hereunder shall be governed
