securities on any form under the Act.

          (f)  "Warrant  Shares" means any shares of Common Stock of the Company

warrant.

      2.  DEMAND REGISTRATION.

          (a)  At any time  following  the  exercise of the Warrant and prior to
the  Registration  of  all of the  Warrant  Shares,  and  subject  to the  other
provisions  of this  Agreement,  Orbiter  shall have the right,  exercisable  by
making a written request (the "Registration  Request") to the Company, to demand
that the  Company  effect the  Registration  of any  Registrable  Securities  in
accordance  with the  provisions  of the Act.  Upon receipt of the  Registration
Request,  the Company  shall be  obligated to register  each of the  Registrable
Securities beneficially owned by Orbiter in the manner set forth in Section 2(b)
hereof.  Any  provision  herein to the  contrary  notwithstanding,  the right to
demand  Registration  pursuant  to this  Section 2 shall be  limited  to one (1)
Registration demand. A right to demand Registration hereunder shall be deemed to
have been  exercised and all of the Company's  demand  Registration  obligations
hereunder shall be deemed to be fully satisfied when the registration  statement
filed on account of such exercise has been declared effective by the Commission.

          (b)  Following receipt of the Registration Request pursuant to Section
2(a) hereof,  the Company  shall (i) file within  ninety (90) days  thereafter a
registration  statement on the appropriate  form under the Act for the shares of

<PAGE>

Common  Stock that the  Company  has been  requested  to  Register;  (ii) if the
applicable  Offering  is pursuant to an  underwriting  agreement,  enter into an
underwriting  agreement in such form as said managing or sole underwriter  shall
require (which must only contain terms and conditions customary for offerings of
equity securities of entities with market capitalizations that are approximately
equal to the  Company's  then  current  market  capitalization  and may  contain
customary  provisions requiring the Company and Orbiter to indemnify and provide
contribution to the underwriter or underwriters of such Offering); and (iii) use
its  reasonable  best  efforts  to have  such  registration  statement  declared
effective as promptly as  practicable  and to remain  effective for at least one
hundred  and twenty  (120) days.  Notwithstanding  any other  provision  hereof,
Orbiter  acknowledges and agrees that there can be no guarantee or warranty from
or by the Company  that any such  registration  statement  will ever be declared
effective by the  Commission,  and that the Company  makes no such  guarantee or
warranty in this Agreement or otherwise.

      3.  PIGGYBACK REGISTRATION.  At any time  following  the  exercise  of the
Warrant and prior to the Registration of all of the Warrant Shares,  and subject
to the other  provisions of this Agreement,  the Company shall advise Orbiter by
written notice at least thirty (30) days prior to the filing of any registration
statement  under the Act by the Company (other than a registration  statement on
Form S-4, Form S-8 or subsequent  similar forms), and will upon the provision of
written notice from Orbiter as described below include in any such  registration
statement such information as may be required to permit a public offering of the
Registrable Securities desired to be registered by Orbiter;  provided,  however,
that if the sole  underwriter or managing  underwriters  advise the Company that
the inclusion in the offering of securities proposed to be sold by Orbiter would
adversely  affect the ability of the Company to  complete  the public  offering,
then the Company shall have no obligation to register any shares held by Orbiter
in connection with such registration  statement.  If Orbiter desires to have its
Registrable  Securities  included  in such  registration  statement,  it must so
advise the Company in writing within fifteen (15) days after the date of receipt
of the Company's notice of registration, setting forth the amount of Registrable
Securities  for  which  registration  is  requested.  Notwithstanding  any other
provision hereof,  Orbiter  acknowledges and agree that there can be no guaranty
or warranty from or by the Company that such registration statement will ever be
declared  effective  by the  Commission,  and  that  the  Company  makes no such
guarantee or warranty in this Agreement or otherwise.

      4.  INFORMATION  TO BE FURNISHED BY ORBITER.  Orbiter shall furnish to the
Company in writing all information  within its possession or knowledge  required
by the applicable  rules and regulations of the Commission and by any applicable
state  securities or blue sky laws  concerning  Orbiter,  the proposed method of
sale or other disposition of the shares of Common Stock being sold by Orbiter in
such Offering,  and the identity of and  compensation to be paid to any proposed
underwriter or underwriters to be employed in connection with such Offering.

      5.  COSTS AND  EXPENSES.  The Company  shall pay all costs and expenses in

Orbiter in connection  with such Offering,  including  without  limitation,  any
transfer taxes, underwriting discounts or commissions.

must be in  writing  and shall be deemed to have been given on the same day when
personally delivered or sent by confirmed facsimile  transmission or on the next
business  day when  delivered  by  receipted  courier  service  or on the  third

                          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 November 18,
2003, Eighty Thousand (80,000) 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 $0.01  (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

<PAGE>

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
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  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,  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.  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 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

                                       3
<PAGE>

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.

         10.  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

stock of any class or any other securities,  or any right or option to subscribe
for, purchase or otherwise acquire any shares of stock of any class or any other
securities (other than this 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
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 wind-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

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.

         7. CERTAIN  DELIVERIES.  The Company shall deliver to the Holder copies
of  all  documents  filed  by the  Company  with  the  Securities  and  Exchange
Commission.

executing the Form of Assignment attached hereto as Exhibit "B") and delivery in
the  same  manner  as in the case of a  negotiable  instrument  transferable  by
