                              EMPLOYMENT AGREEMENT
                                 JOHN M. CODILIS

         THIS EMPLOYMENT AGREEMENT ("Agreement"), which for identification
purposes only is dated the 7th day of February 2000, is entered into by and
between BIOSHIELD TECHNOLOGIES, INC., a Georgia corporation (the "Employer") and
JOHN M. CODILIS, an individual residing in Glen Ellyn, Illinois (the
"Employee").

         WHEREAS, the Employer is in the antimicrobial and biostatic products
development business (the "Business"); and

         WHEREAS, Employer desires to hire Employee and Employee desires to be
employed by the Employer in accordance with the terms of this Agreement.

         NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants and promises contained herein, it is agreed by the parties as
follows:

         SECTION 1. Term. This Agreement commences effective on February 7,
2000, and shall continue until terminated by either party. Termination may be
with or without any reason whatsoever, upon giving thirty (30) days written
notice by one party to another. Notwithstanding the foregoing to the contrary,
termination shall be immediate upon any of the following events:

         (A) Upon the death of Employee.

         (B) By the Employer notifying the Employee in writing that the
         Agreement is being terminated for cause. A termination for cause is
         hereby defined as a termination as a result of theft or
         misappropriation of Employer's assets by Employee, or gross negligence
         of Employee pertaining to the conduct of business on behalf of
         Employer. The disability of Employee shall not be considered cause.

         (C) This Agreement will automatically terminate on August 31, 2003, if

         SECTION 3. Base Salary. Employee shall be paid a "Base Salary" of One
Hundred Seventy-Five Thousand Dollars ($175,000.00) per year, payable on the
same periodic basis as other full-time employees of Employer, as they may be
paid by Employer from time to time; provided, however, that said Base Salary
shall be paid at least on a monthly basis in arrears. In the event that this
Agreement is terminated, then Employee's Base Salary even though stated in
annual terms, shall be prorated through the date of termination. The Employee's
Base Salary shall be increased on an annual basis in an amount at least equal to
the Consumer Price Index cost of living increase for all wage earners in the
Chicago Metropolitan Area.

         SECTION 4. Cash Bonus. In the event that Employee remains an employee
of the Employer beyond August 31, 2000, then the Employer shall promptly adopt a

                           (I) Subject to the provisions of Section 5.02 (a)(iv)
                           below, if Employee is employed by Employer on August

                           (II) Subject to the provisions of Section 5.02

                           an additional one-third (1/3) of the Initial Stock

                           (IV) If either (1) Employee dies prior to September
                           1, 2000, (2) Employer terminates Employee's
                           employment with or without cause prior to September
                           1, 2000, or, (3) Employee's employment is terminated
                           effective as of the Early Termination Date as
                           provided for in Section 5.05 hereof; then Employee
                           shall not be vested in any of the Initial Stock
                           Option, and the entire Initial Stock Option shall
                           lapse. If after August 31, 2000 either, (1) Employee
                           voluntarily terminates his employment with Employer,
                           or (2) Employer terminates Employee's employment for
                           cause, then to the extent that any of the Initial
                           Stock Option shares are not vested, then Employee's
                           Option to purchase the non-vested shares shall lapse.
                           However, if at any time after August 31, 2000, but
                           prior to Employee becoming vested in the entire
                           Initial Stock Option, either Employee dies or
                           Employer terminates Employee's employment without
                           cause, then Employee shall become immediately vested
                           in the entire Initial Stock Option.


                  (B) Whenever Employee is vested pertaining to any portion of
                  the Initial Stock Option, then Employee may exercise his
                  Option to purchase such shares, regardless of Employee's
                  employment status
<PAGE>   7


                  as of the date that the Option is exercised. The Option must
                  be exercised on or before the Exercise Date. If the Option is
                  not exercised on or before the Exercise Date, then the Option
                  shall become an Expired Option and the Option shall lapse. If
                  an Option is timely exercised, then the price per share shall
                  be the Strike Price.

         SECTION 5.03. Primary Objective Stock Option. If the Primary Objective
is satisfied, then the Employee shall automatically be granted an Option to
purchase Twenty-Five Thousand (25,000) shares of Stock (the "Primary Objective
Stock Option") at the Strike Price, regardless of Employee's employment status
as of the date that the Option is exercised. The Primary Objective Stock Option
shall be exercised by Employee on or before the Exercise Date. If the Primary
Objective Stock Option is not exercised by Employee on or before the Exercise
Date, then it shall be considered an Expired Option and it shall lapse.

         SECTION 5.04. Secondary Objective Stock Option. If the Secondary
Objective is satisfied, then the Employee shall automatically be granted an
Option to purchase Twenty-Five Thousand shares of Stock (the "Secondary
Objective Stock Option") at the Strike Price, regardless of Employee's
employment status as of the date that the Option is exercised. The Secondary
Objective Stock Option shall be exercised by Employee on or before the Exercise
Date. If the Secondary Objective Stock Option is not exercised by Employee on or
before the Exercise Date, then the Secondary Objective Stock Option shall be
considered an Expired Option and it shall lapse.

         SECTION 5.05. The Departure Fee. The parties contemplate that on
approximately August 1, 2000, Employer and Employee shall hold the Six Month
Review. At that time, the parties shall decide whether or not to continue this
Agreement. If the parties cannot mutually agree to continue this Agreement, then
this Agreement shall automatically terminate effective August 31,

<PAGE>   8


2000 (the "Early Termination Date"), without the requirement of thirty (30) days
written notice as required in Section 1 hereof. If this Agreement is terminated
(A) as of the Early Termination Date, or (B) by Employer without cause on or
before the Early Termination Date, then Employer shall owe to Employee the
"Departure Fee" which shall be Eighty-Seven Thousand Five Hundred Dollars
($87,500.00). The Departure Fee shall be payable to Employee thirty (30) days
after employment termination. If Employee is paid the Departure Fee, then both
the Primary Objective Stock Option (to the extent earned) and the Secondary
Objective Stock Option (to the extent earned) shall be rescinded and may not be
exercised by Employee. Alternatively, Employee can elect within fifteen (15)
days after employment termination to waive the Departure Fee. If Employee elects
to waive the Departure Fee, then Employee's rights in and to the Primary
Objective Stock Option and the Secondary Objective Stock Option shall not be
rescinded and any such rights, pursuant to such Options, shall remain in full
force and effect.

         SECTION 6. Severance Pay. The parties agree that in the event that
Employee's employment is terminated for any reason after the Early Termination
Date,(2) except in the event of (A) a termination of Employee for cause, (B)
Employee's death, or (C) Employee's voluntary termination; then Employee shall
be paid "Severance Pay". The Severance Pay shall be an amount equal to one (1)
year of Employee's Base Salary, as Base Salary is measured as of the date of
termination. If Employee's employment is terminated on or before the Early
Termination Date, then there shall not be any Severance Pay. Severance Pay may
be payable by Employer to Employee in twelve (12) equal consecutive monthly
installments commencing no later than thirty (30) days after the date of
termination. In the event that Employee breaches the provisions of Section 8(a)
hereof, Employer may discontinue paying Severance Pay to Employee as liquidated
damages.

-----------------
(2) The term Early Termination Date is defined at Section 5.05 hereof as
    August 31, 2000.

shall provide those fringe benefits which are detailed as follows:

         (A) Expenses. Employer agrees to pay for all ordinary and necessary
         business related expenses (in accordance with Employer's policies)

         business related expenses shall include, but are not limited to, all

         (including but not limited to travel between Chicago and Georgia) and

         Twelve Dollars ($12.00) for lunch and Twenty-Five Dollars ($25.00) for
         dinner, plus the full amount of meals incurred while entertaining
         customers and/or prospects.

         (B) During the term of this Agreement, Employee shall be entitled to
         three (3) weeks of vacation during each calendar year, on a
         non-cumulative basis.

         (C) The Employee shall generally be entitled to participate in or

         SECTION 8. Restrictive Covenants. To induce Employer to execute,
deliver and perform this Agreement, Employee agrees as follows:

                  (A) Interference with Business. During the term of this
                  Agreement, and for a period of one (1) year after the
                  termination of this Agreement, neither Employee, nor anyone
                  operating at Employee's direction or for Employee's benefit,
                  shall, on their own account, or as an employee, consultant,
                  partner, member, manager, owner, officer, director or
                  shareholder of any other person, firm, partnership, limited
                  liability company or corporation, or in any other capacity, in
                  any way, directly or indirectly, solicit, divert, take away or
                  interfere with the Business of Employer.

                  (B) Non-Disclosure. During the entire term of this Agreement,
                  and for a period of one (1) year after the termination of this
                  Agreement, Employee shall not disclose to others nor shall
                  Employee use for Employee's financial gain any confidential
                  information pertaining to Employer's Business concepts,
                  pricing, designs, plans, know-how, trade secrets, software,
                  data or other technical items, marketing or other business
                  information which is the property of Employer, pertaining to
                  the operation of Employer's Business.

                  (C) Relief and Remedy. Employee acknowledges and agrees that:

                           (I) The restrictive covenants contained in
                           Subsections (a) and (b) of this Section are

<PAGE>   11

                           reasonable and necessary to protect Employer's
                           legitimate business interests;

                           (II) The restrictive covenants contained in
                           Subsections (a) and (b) of this Section are
                           reasonable and necessary to protect Employer's trade
                           secrets and confidential information;

                           (III) The periods of time provided herein are the
                           minimum periods of time necessary to protect Employer
                           and its successors and assigns, from unauthorized use
                           or disclosure of confidential information and
                           unauthorized use of any goodwill associated with
                           Employer's business. Employee acknowledges and agrees
                           that money damages alone cannot compensate Employer,
                           its successors or assigns, in the event of a breach
                           or violation of the noninterference or nondisclosure
                           covenants contained in this Section, and that
                           injunctive relief is essential for the protection of
                           Employer and its successors and assigns. Accordingly,
                           Employee agrees and consents that in the case of any
                           breach or violation of this Section, Employer may
                           have such injunctive relief, without bond but upon
                           due notice. No waiver of any breach or violation of
                           any of the provisions of this Section shall be
                           implied from

<PAGE>   12


                           forbearance or failure by Employer to take action
                           thereon. To the extent that any provision of this
                           Section is deemed unenforceable by virtue of its
                           scope in terms of length of time or nature of
                           restriction, or as to any one (1) or more of the
                           parties, but may be made enforceable by limitation
                           thereof, the parties agree that the same shall,
                           nevertheless, be enforceable to the fullest extent
                           permissible under the laws and public policies
                           applied in such jurisdiction in which enforcement is
                           sought.

                  (D) Rights Cumulative. The rights and remedies granted to
                  Employer in this Agreement in the event of default are
                  cumulative, and the exercise of any right or remedy, including
                  the right to money damages, shall be without prejudice to the
                  enforcement of any other right or remedy authorized by law or
                  this Agreement.

                  (E) Costs. In the event of any violation by Employee of the
                  restrictive covenants contained herein, and on the condition
                  that Employer prevails in its claim against Employee for
                  relief, then Employee agrees to pay Employer, an amount equal
                  to the aggregate of its reasonable attorneys' fees and court
                  costs.

                  SECTION 9. Place of Employment. During the term of this
Agreement, the Employer's headquarters shall be located in the Atlanta Georgia
area. However, Employee shall maintain a satellite office in his home in Glen
Ellyn, Illinois.

         SECTION 10. Termination Obligations. At the time of his resignation or
termination from the Employer, the Employee shall promptly return to the
Employer all personal property, both tangible and intangible, furnished to or
prepared by the Employee in the course of or incident to his employment, the
Employee hereby acknowledging and agreeing that such property belongs to the
Employer, such that following termination the Employee will not retain any
written or other tangible material containing any proprietary information of the
Employer. Personal property includes, without limitation, all computers,
