                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

         THIS  WARRANT is issued in  connection  with that  certain  Convertible
Promissory  Note in the  principal  amount of  $50,000.00,  dated as of the date
hereof (the "Note").

         GENETIC VECTORS,  INC., a Florida  corporation (the "COMPANY"),  hereby
certifies that, for value received,  MICHAEL AND LOIS HALBERT (the "HOLDER"), or
its registered  permitted assigns,  is entitled,  subject to the terms set forth
below, to purchase from the Company at any time or from time to time before 5:00
P.M.,  Eastern  Time,  on May 8,  2005,  the  number of shares of fully paid and
non-assessable  shares of common stock,  par value $0.001 per share (the "COMMON
STOCK"),  of the  Company as set forth in the Note and at a  purchase  price per
share as set forth in such Note (the "PURCHASE PRICE"). The number and character
of such shares of Common Stock are subject to adjustment as provided herein.

         As used  herein  the  following  terms,  unless the  context  otherwise
requires, have the following respective meanings:

         (a)      The term  "COMPANY"  shall include  Genetic  Vectors,  Inc., a
Florida  corporation,  and any ------- corporation which shall succeed or assume
the obligations of the Company hereunder.

         (b)      The term "COMMON STOCK"  includes the Company's  Common Stock,
par value  $0.001  per share,  as  authorized  on the date  hereof and any other
securities  into which or for which any of such Common Stock may be converted or
exchanged pursuant to a plan of recapitalization,  reorganization,  merger, sale
of assets or otherwise.

         1.       EXERCISE OF WARRANT.
                  -------------------

                  1.1. FULL  EXERCISE.  This Warrant may be exercised in full by
the Holder by  surrender  of this  Warrant,  with the form of Notice of Exercise
attached  hereto as Exhibit "A" (the  "EXERCISE  NOTICE")  duly  executed by the
Holder, to the Company at its principal office,  accompanied by payment, in cash
or by certified or official bank check or wire transfer  payable to the order of
the  Company,  in the amount  obtained  by  multiplying  the number of shares of
Common Stock for which this Warrant is then exercisable by the Purchase Price.

<PAGE>

                  1.2. PARTIAL  EXERCISE.  This Warrant may be exercised in part
by surrender of this Warrant in the manner and at the place  provided in Section
1.1 except that the amount payable by the Holder on such partial  exercise shall
be the amount  obtained by multiplying  (a) the number of shares of Common Stock
designated by the Holder in the Exercise  Notice by (b) the Purchase  Price.  On
any such  partial  exercise,  the  Company  will issue and deliver to the Holder
hereof a new Warrant or Warrants of like tenor, in the name of the Holder hereof
or such  other  person  as such  Holder  (upon  payment  by such  Holder  of any
applicable transfer taxes) may request,  reflecting in the aggregate on the face
or faces thereof for the number of shares of Common Stock for which such Warrant
or Warrants may still be exercised.

         2.       DELIVERY OF STOCK CERTIFICATES,  ETC. ON EXERCISE.  As soon as
practical after the exercise of this Warrant in full or in part, the Company, at
its expense  (including the payment by it of any applicable  issue taxes),  will
cause to be issued in the name of and  delivered to the Holder  hereof,  or such
other  person as such  Holder  (upon  payment  by the  Holder of any  applicable
transfer taxes and, if requested by the Company,  demonstration by the Holder of
compliance  with  applicable  securities  laws) may  direct,  a  certificate  or
certificates  for the number of fully paid and  non-assessable  shares of Common
Stock to which such Holder shall be entitled on such exercise,  plus, in lieu of
any  fractional  share to which such Holder would  otherwise  be entitled,  cash
equal to such fraction  multiplied by the then-current  market value of one full
share, together with any other stock or other securities and property (including
cash,  where  applicable)  to which such Holder is entitled  upon such  exercise
pursuant to Section 1 or otherwise.

         3.       ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

                  3.1.  REORGANIZATION.  If  the  Company  shall  (a)  effect  a
reorganization, (b) consolidate with or merge into any other person or party, or
(c) transfer all or  substantially  all of its properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then, in each such case,  the Holder of this Warrant,  on the exercise
hereof as  provided  in  Section 1 at any time  after the  consummation  of such
reorganization,   consolidation   or  merger  or  the  effective  date  of  such
dissolution  as the case may be,  shall  receive,  in lieu of the  Common  Stock
issuable on such exercise prior to such consummation or such effective date, the
stock and other  securities and property  (including  cash) to which such Holder
would have been  entitled  upon such  consummation  or in  connection  with such
dissolution,  as the case may be, if such Holder had so  exercised  this Warrant
immediately  prior  thereto,  all subject to further  adjustment  thereafter  as
provided herein.

                  3.2.   CONTINUATION   OF  TERMS.   Upon  any   reorganization,
consolidation,  merger or transfer (and any dissolution  following any transfer)
referred to in this  Section 3, this  Warrant  shall  continue in full force and
effect and the terms hereof shall be applicable to the shares of stock and other
securities  and property  receivable  on the exercise of this Warrant  after the
consummation of such  reorganization,  consolidation  or merger or the effective
date of dissolution  following any such transfer,  as the case may be, and shall
be binding upon the issuer of any such stock or other securities,  including, in
the case of any such transfer,  the person acquiring all or substantially all of
the  properties or assets of the Company,  whether or not such person shall have
expressly assumed the terms of this Warrant as provided herein.


                                       2
<PAGE>

         4. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Articles of  Incorporation  or through any  reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the  terms of the  Warrant,  but will at all times in good  faith  assist in the
carrying  out of all such terms and in the  taking of all such  action as may be
necessary or  appropriate  in order to protect the rights of the Holder  against
dilution or other impairment.

         5.       NOTICES OF RECORD DATE, ETC.  In the event of:

                  (a) any taking by the  Company  of a record of the  holders of
any class or securities for the purpose of determining  the holders  thereof who
are  entitled to receive any  dividend  or other  distribution,  or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

                  (b)  any   capital   reorganization   of  the   Company,   any
reclassification  or recapitalization of the capital stock of the Company or any
transfer  of  all  or  substantially  all  the  assets  of  the  Company  to  or
consolidation or merger of the Company with or into any other person, or

                  (c)      any voluntary or involuntary dissolution, liquidation
or winding-up of the Company, or

                  (d) any  proposed  (i)  issue or grant by the  Company  of any
shares  of stock of any  class or any  other  securities,  or (ii) any  right or
option to subscribe  for,  purchase or otherwise  acquire any shares of stock of
any class or (iii) any other securities (other than the issue of Common Stock on
exercise of this  Warrant),  which would  require  the  affirmative  vote of the
shareholders  of the  Company  according  to its  Articles of  Incorporation  or
applicable state law, then and in each such event the Company will mail or cause
to be mailed to the  Holder a notice  specifying  (i) the date on which any such
record is to be taken for the purpose of such  dividend  distribution  or right,
and stating the amount and character of such  dividend,  distribution  or right;
(ii)   the   date  on   which   any   such   reorganization,   reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock shall be entitled to exchange their shares
of  Common  Stock  for  securities  or  other   property   deliverable  on  such
reorganization,  reclassification,  recapitalization,  transfer,  consolidation,
merger,  dissolution,  liquidation  or  winding-up;  and  (iii) the  amount  and
character  of any stock or other  securities,  or rights or options with respect
thereto,  proposed to be issued or granted,  the date of such proposed  issue or
grant and the persons or class of persons to whom such  proposed  issue or grant
is to be offered or made.  Such notice shall be mailed at least twenty (20) days
prior to the date  specified  in such  notice on which any such  action is to be
taken.

         6.  RESERVATION OF STOCK  ISSUABLE ON EXERCISE OF WARRANT.  The Company
will at all times reserve and keep  available,  solely for issuance and delivery
on the  exercise of this  Warrant,  all shares of Common Stock from time to time
issuable on the exercise of this Warrant.

endorsed,  to the Company,  the Company at its expense will issue and deliver to
or on the order of the Holder  thereof a new  Warrant or Warrants of like tenor,
in the name of such Holder or such other person as such Holder (upon  payment by
such Holder of any  applicable  transfer taxes and, if requested by the Company,
demonstration by such Holder of compliance with applicable  securities laws) may
direct,  calling in the aggregate on the face or faces thereof for the number of
shares  of  Common  Stock  called  for on the face or faces  of the  Warrant  or

         11. GOVERNING LAW. This Warrant and the rights of the parties hereunder
shall be governed by and construed in  accordance  with the laws of the State of
Florida,  without regard to its conflicts of law principles.  All parties hereto
(i) agree that any legal suit,  action or proceeding  arising out of or relating
to this  Warrant  shall  be  instituted  only in a  federal  or  state  court in
Miami-Dade  County,  Florida;  (ii)  waive any  objection  which they may now or
hereafter  have  to the  laying  of  the  venue  of any  such  suit,  action  or
proceeding;  and (iii) irrevocably submit to the jurisdiction of such federal or
state  court  in  Miami-Dade  County,  Florida  in  any  such  suit,  action  or
proceeding,  but such consent  shall not  constitute a general  appearance or be
available  to any other person who is not a party to this  Warrant.  All parties
hereto  agree  that  the  mailing  of any  processing  of any  suit,  action  or
proceeding  in  accordance  with the notice  provisions  of this  Warrant  shall
constitute personal service thereof.

         12. ENTIRE AGREEMENT;  WAIVER OF BREACH.  This Warrant  constitutes the
entire  agreement  among the  parties  and  supersedes  any prior  agreement  or
understanding  among them with respect to the subject matter hereof,  and it may
not be modified or amended in any manner other than as provided  herein,  and no
waiver  of any  breach  or  condition  of this  Warrant  shall be deemed to have
occurred  unless  such waiver is in writing,  signed by the party  against  whom
enforcement  is  sought,  and no waiver  shall be  claimed to be a waiver of any
subsequent breach or condition of a like or different nature.

         13.  SEVERABILITY.  If any  provision  of this  Warrant  shall  be held
invalid or unenforceable,  such invalidity or unenforceability shall attach only
to such  provision  and shall not in any  manner  affect  or render  invalid  or
unenforceable  any other severable  provision of this Warrant,  and this Warrant
shall be carried out as if any such invalid or unenforceable  provision were not
contained herein.

         14.  AMENDMENT.  This  Warrant  and any  term  hereof  may be  changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. 15. Restrictions on  Transferability;  Restrictive Legend. The Holder
acknowledges  that the shares of Common  Stock  issuable  upon  exercise of this
Warrant  are  subject  to  restrictions   under  applicable  Federal  and  state
securities  laws. Each  certificate  representing  shares of Common Stock issued
shall, upon the exercise of this Warrant, bear the following legends in addition
to such other restrictive legends as may be required by law:

         "The shares  represented by this  certificate  have not been registered
under  the  Securities  Act of  1933,  as  amended  (the  "ACT"),  or any  state
securities  laws,  and no sale or transfer  thereof  may be effected  without an
effective  registration  statement  or an  opinion of  counsel  for the  Holder,
satisfactory  to the  Company and its  counsel,  that such  registration  is not
required under the Act and any applicable state securities laws."
