         4.       Compensation and Related Matters.

                  (a)    Salary. During the Employment Period, the Company
         shall pay the Executive a salary of Two hundred forty thousand DOLLARS
         ($240,000.00) annually (the "Salary").

                  (b)    Bonus. The Executive shall also be eligible for an
         annual bonus up to 100% of the Executive's Salary. The President and
         Chief Executive Officer of the Company shall recommend to the
         Compensation Committee of the Board of Directors whether Executive
         shall receive a bonus and, if so, the amount of such bonus, based upon
         quantifiable deliverables and objectives determined by the President
         and Chief Executive Officer and/or the Compensation Committee of the
         Board of Directors. Executive understands and agrees that the
         Compensation Committee of the Board of Directors has sole discretion
         to determine if Executive will receive a bonus and, if so, the amount
         of such bonus.

                  (c)    Stock Options. The Company shall recommend to the
         Compensation Committee of the Board of Directors of the Company that
         Executive be granted as of the date of this Agreement an option to
         purchase 200,000 shares of the Company's common stock at a price to be
         determined by such committee with the shares to be exercisable in one
         third increments on the first, second and third anniversaries of
         grant, respectively. The Company shall also recommend to the
         Compensation Committee of the Board of Directors of BioShield
         Technologies, Inc. that Executive be granted as of November 17, 1999,
         an option to purchase 50,000 shares of the common stock of BioShield
         Technologies, Inc. at an exercise price per share of the mean between
         the high and low sales price of the stock on the date of grant with
         the shares to be exercisable in one third increments on the first,
         second and third anniversaries of grant, respectively.

                  (d)    Vacation. During the Employment Period Executive shall
         be entitled to twenty days of vacation during each calendar year.
         These days of vacation shall be non-cumulative which means that he
         receives the twenty days of vacation at the beginning of each calendar
         year for use during the calendar year. Days of vacation not used
         during a calendar year shall not carry over and shall be forfeited. In
         the event, the Executive requests time off between signing of this
         agreement and December 31, 1999, the Executive can discuss the request
         with the Chief Executive Officer.

                  (e)    Business Expenses. The Company will reimburse the
         Executive for reasonable bona fide business expenses incurred on
         behalf of the Company in the ordinary course of business, provided,
         however, that the expense is otherwise deductible by the Company as an
         ordinary and necessary business expense for federal income tax
         purposes.

                  (f)    General Benefits. The Executive shall generally be
         entitled to participate in or receive health, long-term disability
         insurance, and similar benefits as the Company provides from time to
         time to its executives. The Executive shall cooperate with the
         issuance of a key man term life insurance policy for the benefit of
         the Company, if so requested by the Company.

         related to the educational requirements to maintain his status as a
         Certified Public Accountant.

                  (h)    Health Club. Executive shall receive reimbursement for
         the monthly dues of a Health Club of his choice up to $300.00 per
         month; provided, however, that no reimbursement will be paid to
         Executive unless such a payment may be deducted by the Company as an
         ordinary business expense.

                  (i)    Withholding. All salary, bonus payments, stock option
         exercises, benefit payments and other payments due to Executive under

         payment any required taxes or other governmental withholdings,
         insurance or benefit payments and similar items.

         5.       Termination or Resignation.

                  (a)    Termination. The Executive's employment hereunder
         shall be, or may be, as the case may be, terminated and shall
         constitute a "Termination" under the following circumstances:

                         (i)       Death. The Executive's employment hereunder
                  shall terminate upon his death.

                         (ii)      Disability. The Executive's employment
                  hereunder shall terminate on the Executive's physical or
                  mental disability or infirmity which, in the opinion of a
                  competent physician selected by the Board, renders the
                  Executive unable to perform his duties under this Agreement
                  for more than 30 days during any 120-day period.

                         (iii)     With Cause. The Company may terminate the
                  Executive's employment hereunder for Cause. "Cause" shall
                  mean (i) Employee's material breach of any of the terms of
                  this Agreement, (ii) his conviction of a crime involving
                  moral turpitude or constituting a felony under the laws of
                  any state, the District of Columbia or of the United States,
                  (iii) his gross negligence, willful misconduct or fraud in
                  the performance of his duties hereunder; (iv) his repeated
                  failure or refusal to follow the directives of the Board; or
                  (v) inappropriate business conduct that is directly related
                  to Executive's activities on behalf of the Company that may
                  cause material harm to the business interests of the Company.

                         (iv)      By the Company for Any Other Reason. The
                  Company may terminate the Executive's employment hereunder at
                  any time for any reason other than the Executive's Death or
                  Disability or for Cause.

                         (v)       Termination by Executive for Good Reason.
                  The Executive may terminate his employment with the Company
                  at any time for "Good Reason." "Good Reason" shall mean
                  without the express written consent of the Executive the
                  occurrence of any of the following events unless such events
                  are substantially corrected within thirty (30) days following
                  written notification by Executive to the



                                     - 3 -
   4

                  Company that he intends to terminate his employment hereunder
                  for one of the following reasons: (i) any material reduction
                  or diminution in the duties, responsibilities and status of
                  Executive's position; (ii) a material breach by the company
                  of any provision of this Agreement; (iii) a relocation by the
                  Company of its principal place of business to another city or
                  state more than fifty (50) miles from Norcross, Georgia and
                  the Company requires Executive to relocate to such new
                  principal place of business; and (iv) the occurrence of a
                  Change in Control. The Executive understands, acknowledges
                  and agrees that any voluntary resignation by him shall not
                  constitute Good Reason. Further Executive understands,
                  acknowledges and agrees that if the Company is separated from
                  its parent BioShield Technologies, Inc. through an initial
                  public offering, stock dividend or otherwise and he no longer
                  serves as chief financial officer of BioShield Technologies,
                  Inc., this will not constitute Good Reason under this
                  Agreement.

                           As used in this Agreement, "Change of Control" means
                  the occurrence of any of the following: (i) the adoption of a
                  plan relating to the liquidation or dissolution of the
                  Company, (ii) the consummation of any transaction (including,
                  without limitation, any merger or consolidation) the result
                  of which is that any person or group, other than Jacques
                  Elfersy or Timothy C. Moses or their affiliates (the
                  "Principals"), becomes the "beneficial owner" (as such term
                  is defined in Rule 13d-3 and Rule 13d-5 under the Securities
                  Exchange Act of 1934), directly or indirectly, of more than
                  fifty percent (50%) of the total voting power of the total
                  outstanding shares of the Company on a fully diluted basis,
                  or (iii) the consummation of the first transaction
                  (including, without limitation, any merger or consolidation)
                  the result of which is that any person or group, other than
                  the Principals, becomes the beneficial owner, directly or
                  indirectly, of more than fifty percent (50%) of the total
                  voting power of the total outstanding voting stock of the
                  Company on a fully diluted basis.

                           Notwithstanding anything to the contrary above the
                  sale of the Company's stock to the public in an initial
                  public offering or otherwise shall not constitute a Change in
                  Control.

                           (vi)    Termination by Executive for Any Reason
                  Other Than Good Reason. The Executive may voluntarily resign
                  his position and terminate his employment and Salary with the
                  Company at any time, with or without cause, by delivery of a
                  written notice of resignation to the Company (the "Notice of
                  Resignation"). The Notice of Resignation shall set forth the
                  date such resignation shall become effective (the "Date of
                  Resignation"), which date shall, in any event, be at least
                  thirty (30) days and no more than sixty (60) days from the
                  date the Notice of Resignation is delivered to the Company.
                  At its option, the Company may reduce such notice period to
                  any length, upon written notice to the Executive.

                  (b)      Notice of Termination by Company. Any termination of
         the Executive's employment by the Company shall be communicated by
         written Notice of Termination to the Executive. For purposes of this
         Agreement, a "Notice of Termination" shall mean a notice that shall
         indicate the specific termination provision in this Agreement relied
         upon and shall set forth, if applicable, in reasonable detail the
         facts and circumstances claimed to



                                     - 4 -
   5

         provide a basis for termination of the Executive's employment under
         the provision so indicated. "Date of Termination" shall mean (i) if
         the Executive's employment is terminated by his death, the date of his
         death, (ii) if the Executive's employment is terminated by reason of
         his disability, the date of the opinion of the physician referred to
         in Section 5(a)(ii), above, (iii) if the Executive's employment is
         terminated by the Company for Cause pursuant to subsection 5(a)(iii)
         above or without Cause pursuant to subsection 5(a)(iv) above, the date
         specified in the Notice of Termination and (iv) if the Executive
         voluntarily resigns pursuant to subsection 5(c) above, the date of the
         Notice of Resignation.

                  (c)    Executive is Employee-At-Will. Notwithstanding the
         Term of this Agreement and the annual salary to be paid to the
         Executive during his employment with the Company, nothing in this
         Agreement should be construed as to confer any right of the Executive
         to be employed by the Company for a fixed or definite term. Subject to
         Section 6 hereof, the Executive hereby agrees that the Company may
         dismiss him under subsection 5(a) hereof without regard (i) to any
         general or specific policies (whether written or oral) of the Company
         relating to the employment or termination of its employees, or (ii) to
         any statements made to the Executive, whether made orally or contained
         in any document, pertaining to the Executive's relationship with the
         Company. The Executive's employment with the Company is at will and
         may be terminated by the Company at any time by delivery of a Notice
         of Termination to the Executive, for any reason, with or without
         cause, without liability except with respect to the payments provided
         for by Section 6(d).

                  (d)    Termination Obligations. In exchange for the Company
         entering into the Agreement and payment of the Severance Payments
         provided for in Sections 6(b) and 6(e) herein, the Executive agrees
         that, at the time of his resignation or termination from the Company:

                         (i)       The Executive will promptly return to the
                  Company all personal property, both tangible and intangible,
                  furnished to or prepared by the Executive in the course of or
                  incident to his employment, the Executive hereby
                  acknowledging and agreeing that such property belongs to the
                  Company, such that following termination the Executive will
                  not retain any written or other tangible material containing
                  any proprietary information of the Company. "Personal
                  property" includes, without limitation, all computers,
                  cellular phones, company credit cards, access keys, books,
                  manuals, records, reports, notes, contracts, lists and other
                  documents or materials, or copies thereof (including computer
                  files), and all other proprietary information relating to the
                  business of the Company.

                         (ii)      The Executive will tender his resignation
                  from all offices and directorships then held with the
                  Company.

                         (iii)     The Executive will execute a release
                  acceptable to the Company of all liability of the Company,
                  and its directors, officers, shareholders, employees, agents
                  and attorneys, to the Executive in connection with or arising
                  out of his employment with the Company, except with respect
                  to any Severance Payments under Sections 6(b) or 6(d) which
                  may be payable to him under the terms of the Agreement.

                         (iv)      The representations and warranties contained
                  herein and the Executive's obligations under Sections 5(d),
                  7, 8, 9 and 15 through 18 shall survive termination of the

         Company shall have no obligation to compensate the Executive following
         the Date of Resignation, except for the payment of accrued and unpaid
         salary pursuant to Section 4(a) through the Date of Resignation. In
         any event, at the Executive's own expense, the Executive and his
         dependents shall be entitled to any continuation of health insurance
         coverage rights under any applicable law.

                  (e)    Termination Without Cause by Company and Termination
         For Good Reason by Executive. If the Company terminates Executive's
         employment with the Company pursuant to Section 5(a)(iv) or the
         Executive terminates his employment with the Company pursuant to
         Section 5(a)(vi) hereof, the Company shall pay to Executive all Salary
         payable pursuant to Section 4(a), as Severance Payments through a
         period ending twelve (12) months following the Date of Termination.
         Further beginning one month after the Date of Termination the Company
         shall pay to Executive in six monthly installments an amount equal to
         the average of all annual bonuses paid or payable to Executive during
         the Term of this agreement prior to the Date of Termination. In
         addition for the period that the Severance Payments are being paid to
         the Executive, the Executive and the Executive's family shall be
         entitled to receive welfare plan benefits (other than continued group
         long-term disability coverage) generally available to executives of
         the Company with comparable



                                     - 6 -
   7

         responsibilities or positions at the same cost to the Executive as is
         charged to such similar executives from time to time for comparable
         coverage. The Company shall have no other obligation to compensate the
         Executive following the Date of Termination.

                  (f)    Any Severance Payments made pursuant to this Section 6
         shall be payable in accordance with the Company's regular payroll
         practices. The obligation of the Company to make the Severance
         Payments to the Executive is expressly conditioned upon the Executive
         complying and continuing to comply with his obligations and covenants
         under Sections 5(d), 7 and 8 of this Agreement following termination
         of his employment with the Company.

7.       Confidentiality and Non-Solicitation Covenants.

                  (a)    Confidentiality. In addition to the agreements set
         forth in Section 5(e), the Executive hereby agrees that the Executive
         will not, during the Employment Period or at any time thereafter
         directly or indirectly disclose or make available to any person, firm,
         corporation, association or other entity for any reason or purpose
         whatsoever, any Confidential Information (as defined below). The
         Executive agrees that, upon Termination of his employment with the
         Company, all Confidential Information in his possession that is in
         written or other tangible form (together with all copies or duplicates
         thereof, including computer files) shall be returned to the Company
         and shall not be retained by the Executive or furnished to any third
         party, in any form except as provided herein; provided, however, that
         the Executive shall not be obligated to treat as confidential, or
         return to the Company copies of any Confidential Information that (i)
         was publicly known at the time of disclosure to the Executive, (ii)
         becomes publicly known or available thereafter, but prior to the Date
         of Termination, other than by any means in violation of this Agreement
         or any other duty owed to the Company by any person or entity or (iii)
         is lawfully disclosed to the Executive by a third party. As used in
         this Agreement the term "Confidential Information" means: information
         disclosed to the Executive or known by the Executive as a consequence
         of or through his relationship with the Company, about the directors,
         officers, shareholders, customers, employees, investors, business
         methods, public relations methods, organization, procedures or
         finances, including, without limitation, information of or relating to
         shareholder , customer or investor lists of the Company and any
         affiliate.

                  (b)    Non-Solicitation. In addition, the Executive hereby
         agrees that during the Employment Period, and for a period of one (1)
         year thereafter, regardless of the reason or circumstances of
         Termination of employment with the Company, the Executive will not,
         directly or indirectly, solicit or attempt to solicit away from
         Company any of its officers or employees or offer employment to any
         person who, at any time during the six (6) months immediately
         preceding the Date of Termination, is or was an officer or employee of
         Company.

         8.       Covenant Not to Compete. The Executive agrees that during the
Employment Period he will devote full-time to the business of the Company and
not engage in any type of business which engages in the medical internet,
online pharmacy and information services or any other related businesses,
including but not limited to all aspects of the Business. Subject to such
full-time requirement and the restrictions set forth below in this Section 8
and Section 3(c) above, the Executive shall be permitted to continue his
existing business investments and activities and may pursue additional business
investments; provided that the Executive not serve as a director or



                                     - 7 -
   8

officer of any public company resulting from such business investments. The
Executive agrees that, from the end of the Employment Period through a one (1)
year period thereafter, he shall not, within the Protected Territory (as
defined hereinafter), (i) invest in, manage, consult or participate in any way
in any other business in competition with the Business (in either an active or
passive manner), (ii) participate in or advise any business which has business
activities similar to the Business, or (iii) act for or on behalf of any
business that intends to enter or participate in any business which has any
business activities similar to the Business, in each case unless the
independent members of the Company's Board determines that such action is in
the best interests of the Company. Notwithstanding the foregoing, the Executive
may purchase stock as a stockholder in any publicly traded company, including
any company which is involved in the development or operation of a medical
internet site in the Protected Territory; provided that the Executive does not
own (together or separately or through his affiliates) more than five percent
(5%) of any company (other than the Company) engaged in a business which is
competitive with the Business of the Company within the Protected Territory. In
addition, the Executive shall not invest (directly or indirectly) in any
business which is competitive with the Business operating within the Protected
Territory unless the independent members of the Company's Board determines that
such an investment is in the best interests of the Company. For purposes of
this Agreement, the "Protected Territory" shall mean that area within a one
hundred (100) mile radius of the principal offices of the Company at the Date
of Termination.

         9.      Injunctive Relief and Enforcement. In the event of breach by
the Executive of the terms of Sections 5(d), 7 or 8, if the Company believes it
is suffering irreparable injury, then the Company shall, notwithstanding the
requirement of final and binding arbitration contemplated in Section 16 below,
be entitled to institute legal proceedings to enforce the specific performance
of this Agreement by the Executive and to enjoin the Executive from any further
violation of Sections 5(d), 7 or 8 and to exercise such remedies cumulatively
or in conjunction with all other rights and remedies provided by law and not
otherwise limited by this Agreement. The Executive acknowledges, however, that
the remedies at law for any breach by him of the provisions of Sections 5(d), 7
or 8 may be inadequate. In addition, in the event the covenants set forth in
Sections 5(d), 7 or 8 shall be determined by any court of competent
jurisdiction to be unenforceable by reason of extending for too great a period
of time or over too great a geographical area, by reason of being too
restrictive or expansive, or by constituting an unlawful restraint of trade in
any other respect, each such covenant shall be interpreted to extend over the
maximum period of time and over a maximum geographical area for which it may be
enforceable, and to the maximum extent in all other respects as to which it may
be enforceable, and enforced as so interpreted, all as determined by such court
in such action.

         10.     Notice. For the purposes of this Agreement, notices, demands
and all other communications provided for in this Agreement shall be in writing
and shall be deemed to have been duly given when personally delivered when
transmitted by telecopy with written confirmation of transmission and receipt,
three (3) days after deposit in the U.S. mail, first class, with adequate
postage thereon, or one (1) day after delivery to an overnight air courier
guaranteeing next day delivery, addressed as follows:

or to such other address as any party may have furnished to the others in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt as provided above.

         11.      Severability. The invalidity or unenforceability of any
provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision of this Agreement, which shall remain in
full force and effect; provided, however, that if any one or more of the terms
contained in Sections 5(d), 7 or 8 hereto shall for any reason be held by any
court of competent jurisdiction to be unenforceable by reason of extending for
too great a period of time or over too great a geographical area, by reason of
being too restrictive or expansive, or by constituting an unlawful restraint of
trade in any other respect, then such covenant shall not be deleted but shall
be reformed and constructed in a manner to enable it to be enforced to the
extent compatible with applicable law.

         12.      Assignment. This Agreement may not be assigned by the
Executive, but may be assigned by the Company to any successor to its business
and will inure to the benefit and be binding upon any such successor.

         13.      Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         14.      Headings. The headings contained herein are for reference
purposes only and shall not in any way affect the meaning or interpretation of
this Agreement.

         15.      Choice of Law. This Agreement shall be construed, interpreted
and the rights of the parties determined in accordance with the laws of the
State of Georgia (without reference to the choice of law provisions of
Georgia), except with respect to matters of law concerning the internal
corporate affairs of any corporate entity which is a party to or the subject of
this Agreement, and as to those matters the law of the jurisdiction under which
the respective entity derives its powers shall govern.

         16.      Arbitration. Absent any irreparable injury being suffered by
the Company entitling the Company to seek injunctive relief against the
Executive pursuant to Section 9 hereof, in the



                                     - 9 -
   10
event there shall be a dispute among the parties arising out of or relating to
this Agreement, or the breach thereof, the parties agree that such dispute shall
be resolved by final and binding arbitration in Atlanta, Georgia under the rules
of the American Arbitration Association. Any award issued as a result of such
arbitration shall be final and binding between the parties thereto, and shall be
enforceable by any court having jurisdiction over the party against whom
enforcement is sought. The fees and expenses relating to such arbitration (with
the exception of the Executive's attorneys' fees, if any) or any action to
enforce an arbitration award shall be shared equally by the Company and the
Executive.

         15.      Entire Agreement. This Agreement contains the entire
agreement and understanding between the Company and the Executive with respect
to the employment of the Executive by the Company as contemplated hereby, and
no representations, promises, agreements or understandings, written or oral,
not herein contained shall be of any force or effect. This Agreement shall not
be changed unless in writing and signed by both the Executive and the Board of
the Company.

         18.      Board Approval. In any case in which this Agreement provides
for the approval, review or determination of the Board in connection with the
Executive's compensation, benefits, termination or compliance with restrictive
covenants herein expressed, then such approval, review or determination shall
be deemed a "Director's conflicting interest transaction", subject to the
procedures required by O.C.G.A. ss. 14-2-860 et seq.

         19.      The Executive's Acknowledgment. The Executive acknowledges he
                  has had the opportunity to consult with independent counsel
                  of his own choice concerning this Agreement, and he has read
                  and understands the Agreement, is fully aware of its legal
                  effect, and has entered into it freely based on his own
                  judgment.

                  IN WITNESS WHEREOF, the parties have executed this Employment
         Agreement as of the date and year first above written.
