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

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "COMPANY"),  hereby
certifies   that,   for   value   received,    THE   ORBITER   FUND,   LTD.,   a
________________________ (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 December 21,
2004,  One  Hundred  Twenty  Thousand   (120,000)   shares  of  fully  paid  and
non-assessable  shares of common stock,  par value $0.001 per share (the "COMMON
STOCK"),  of the Company at a purchase  price per share of $1.00 (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  subscription  attached
hereto as EXHIBIT "A" (the "SUBSCRIPTION  FORM") 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.

            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 Subscription  Form by (b) the Purchase Price. On


<PAGE>

any such  partial  exercise,  the Company  will issue and deliver to or upon the
order of the Holder hereof a new Warrant or Warrants of like tenor,  in the name
of the Holder  hereof or such other person as the 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 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.

      4.  ADDITIONAL WARRANTS. Upon the satisfaction of either (a) the Company's
full payment of all of the outstanding obligations under that certain Promissory
Note (the "Note") of even date  herewith  made by the Company and payable to the
Holder or (b) a closing of an offering  of  securities,  whether  through one or


                                        2
<PAGE>

more private  placements  or secondary  public  offerings,  in which the Company
raises  gross  proceeds  from  such  transaction  or  transactions  of at  least
$1,500,000,  the  Company  shall  grant to the  Holder  additional  warrants  to
purchase  from the  Company at any time or from time to time  before  5:00 p.m.,
Eastern Time, on the fifth anniversary of the grant of such additional  warrants
to the Holder, One Hundred and Fifty Thousand (150,000) shares of fully paid and
non-assessable  Common  Stock at a  purchase  price  per  share  of  $3.00  (the
"PURCHASE PRICE").

All warrants to be granted pursuant to the immediately  preceding sentence shall
be granted  pursuant to a new Warrant in the same form as this  Warrant,  except
that such Warrant shall contain the following provision:

          Any provision  herein to the contrary  notwithstanding,
          no  adjustment  in the Purchase  Price shall be made in
          respect of the issuance of additional  shares of Common
          Stock  of  the  Company  (or  upon  the  conversion  or
          exchange of securities convertible or exchangeable into
          shares of Common  Stock)  unless  after the date hereof
          (a) the aggregate  consideration  to be received by the
          Company for the issuance of such  additional  shares of
          Common  Stock,  whether  through  one or  more  private
          placements or secondary  public  offerings (or upon the
          conversion  or exchange of  securities  convertible  or
          exchangeable  into shares of Common Stock), is at least
          $500,000  and (b) the  consideration  per  share for an
          additional  share of Common Stock (or the conversion or
          exchange  price with respect to securities  convertible
          or  exchangeable  into  shares of  Common  Stock) to be
          issued  by the  Company  is less  than  $3.00.  In such
          event,  the Purchase  Price shall be reduced to a price
          (calculated   to  the  nearest   cent)   determined  by
          multiplying  such  Purchase  Price by a  fraction,  the
          numerator  of which  shall be the  number  of shares of
          Common  Stock  outstanding  immediately  prior  to such
          issue plus the number of shares of Common  Stock  which
          the aggregate consideration received by the Company for
          the total number of  additional  shares of Common Stock
          so issued  would  purchase  at such  Purchase  Price in
          effect  immediately  prior  to such  issuance,  and the
          denominator  of which  shall be the number of shares of
          Common  Stock  outstanding  immediately  prior  to such
          issue  plus the  number  of such  additional  shares of
          Common Stock so issued.

      5.  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.

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

securities  (other than the issue of Common Stock on exercise of the Warrant) in
connection   with  any   reorganization,   reclassification,   recapitalization,
transfer, consolidation,  merger, dissolution,  liquidation or wind up, then and
in each such event the  Company  will mail or cause to be mailed to the Holder a

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,
