Item 1.           DESCRIPTION OF BUSINESS.
- ------------------------------------------

INTRODUCTION

         Genetic Vectors, Inc. (the "Company" or "Genetic Vectors") had cash and
cash equivalents of $109,924 as of December 31, 1998 compared to $2.1 million as
of December 31, 1997.  The Company  projects  that such funds will be completely
exhausted  on or before the end of April  1999.  In the  absence  of  additional
capital, the  Company  will be required  to  significantly  curtail or cease its
business  activities.  The Company's ability to continue its business activities
is  completely  dependent on such  additional  capital and its failure to obtain
such capital will have a material  adverse  effect on the  Company's  ability to
continue its business activities.  The Company's description of its business and
other  information  contained in this Form 10-KSB and the  Company's  ability to
continue  its  business  as  described  herein is  completely  dependent  on the
Company's ability to obtain significant additional capital.

         On March 31,  1999,  Genetic  Vectors,  Inc.  (the  "Company")  filed a
Notification  of Late Filing on Form 12b-25 with respect to its Annual Report on
Form 10-KSB for the year ended  December 31,  1998.  At the time of this filing,
the Company intended to file its Annual Report on Form 10-KSB on or before April
15, 1999.  Subsequent to this filing,  the Company  learned from its independent
public  accountants  that they  could  after  additional  review  only  render a
disclaimer  of  opinion  in  connection  with the  Company's  audited  financial
statements.  The  Company's  auditors  have  advised the  company  that it would
re-evaluate  its  position if the Company  obtains a commitment  for  additional
financing.  The auditors  have not yet  completed  their audit of the  Company's
financial  statements and therefore the disclaimer of opinion cannot be obtained
without additional effort and expense.  The Company believes that the disclaimer
of opinion is solely  attributable  to the  Company's  cash  shortage and is not
attributable  to  any   discrepancies   in  its  financial   statements  or  any
disagreements  with its auditors.  To preserve  cash, the Company has decided to
include unaudited financial  statements in lieu of audited financial  statements
containing  the  disclaimer  of  opinion.  In the  opinion of the  Company,  the
unaudited  financial  statements included in Exhibit "A" include all adjustments
(consisting  of  normal  recurring  accruals)  which  are  necessary  for a fair
presentation of the results for the periods  presented  therein.  For additional
information  concerning the Company's current financial situation,  see "Certain
Business  Risk Factors - Future  Capital  Needs and  Uncertainty  of  Additional
Financing"; "Certain Business Risk Factors - Ability to Continue to Operate as a
Going Concern";  and "Management's Plan of Operation and Discussion and Analysis
- - Additional Fund Raising Activities."

GENERAL INFORMATION

         The Company is a  biotechnology  company which intends to specialize in
the   development   of   diagnostic   and   quality   control   tools   for  the
biopharmaceutical, food and beverage industries. The Company was founded in 1991
by Dr. Mead McCabe (the  Chairman of the Board of  Directors of the Company) who
invented  a  new  nucleic  acid   labeling   and   detection   technology   (the
"Technology").  The  Technology  consists  of patents  and  patent  applications
originally  filed in the name of or for the benefit of the  University of Miami,
and  unpatented  confidential  and  non-confidential  know-how,  which is either
proprietary  or in the public domain.  Part of the  Technology  relates to a new

                                       2

<PAGE>

nucleic acid and method  described in University of Miami  Invention  Disclosure
UM90-16,  which  invention  was  made  under  a grant  from  the  United  States
Government.  Additional  nucleic acids and methods were described in the patents
and  patent  applications  filed  in the  name  of or  for  the  benefit  of the
University of Miami,  some of which were made using University  facilities.  The
antibody was described in University of Miami Invention  Disclosure  UM87-90 and
its  preparation  is the subject of a published  paper and an  abandoned  patent
application which is not available to the public.

         The Technology is the basis for the Company's initial product line, the
EpiDNA(TM),  which includes the Company's first product, the Picogram Assay (the
"Picogram  Assay").  A second proposed  product line,  EasyID(TM),  combines the
EpiDNA  technology  with gene probes in kits for the detection of yeasts.  These
kits are intended for quality control in the food and beverage  industry and for
identification of proprietary yeasts in the brewing and wine-making industry.

         After removing the Picogram Assay from the marketplace during the third
quarter of 1997, the Company has completed the refinement of the EpiDNA Picogram
Assay Kit (the  "Picogram  Assay  Kit").  During the  twelve-month  period ended
December  31,  1998,  the Company has not  generated  significant  revenues  and
remains  largely  a  development  stage  company.  In  July  1998,  the  Company
reintroduced the Picogram Assay Kit to the marketplace and is closely monitoring
its market  acceptance.  The  Company's  cash  shortage  limited  the  Company's
marketing efforts to support the reintroduction of the Picogram Assay. There can
be  no  assurances  that  the  Picogram  Assay  Kit  will  be  accepted  by  the
marketplace.

EPIDNA TECHNOLOGY

         DETECTION  OF  NUCLEIC  ACIDS.  The  EpiDNA  technology  is  a  broadly
applicable  method for labeling and detecting  nucleic acids,  particularly DNA.
The  importance of the ability to attach labels to nucleic acids arises from the
use of nucleic  acids as probes to  identify,  locate and isolate DNA  fragments
containing a single gene in a mixture of DNA fragments  containing  thousands of
different  genes.  DNA labeling  technology  is  analogous  to the  photographic
development  process.  The label makes the results of esoteric DNA hybridization
reactions  visible to the naked eye in the same sense that developing  solutions
render the latent  image in a  photograph  visible.  The visual  results of this
process are pictures of DNA hybrids or DNA fingerprints. Nucleic acid probes are
usually labeled with radioactivity so that the probe and the gene to which it is
bound can be located. The use of non-radioactive labels on probes is becoming an
increasingly  attractive  alternative  because of the  dangers  associated  with
radioactivity  and the expense of disposing  of  radioactive  waste.  The EpiDNA
technology can be used to make these types of  non-radioactive  labeled  nucleic
acid probes.


         The EpiDNA labeling  technology involves a versatile chemical procedure
for attaching labels to nucleic acids.  Genetic Vectors believes this process is
unique in its ability to attach a variety of labels to nucleic acids, regardless
of the size of the nucleic acid. The process is normally  completed within a few
hours,  and can be  accomplished  in a single  test tube with no loss of nucleic
acid.  The Company  believes that scaling the reaction up to  production  levels
(milligram  and gram  amounts of nucleic  acids) is  possible.  The core  EpiDNA
technology is suited for the  attachment  of any  detectable  molecule  (such as
biotin,  fluorescent  or  phosphorescent  compounds,  enzymes or  chelators)  to
nucleic acids.

                                       3

<PAGE>

         The EpiDNA technology is not restricted to the labeling of probes,  but
can also  provide  a method  to  accurately  measure  nucleic  acids at very low
concentrations. This characteristic of the Technology provides the basis for the
Picogram Assay which is targeted to process  development and monitoring,  and to
quality control and research laboratories.

         THE   EPIDNA    PICOGRAM    ASSAY.    Processes    for    manufacturing
biopharmaceuticals,  such as monoclonal  antibodies  and  recombinant  proteins,
result in potentially harmful  contamination with DNA, the material that carries
the  genetic  code and could  carry  cancer-causing  oncogenes.  FDA  guidelines
recommend that manufacturers monitor the content of DNA to assure that the level
of DNA does not exceed 100 picograms per injected  dose.  Under FDA  guidelines,
each biopharmaceutical manufacturer must devise its own in-house quality control
protocol to determine  the purity of each  product.  Companies are free to adapt
current technology, including commercially available assays, to this purpose.


         The Picogram Assay combines chemical and  immunochemical  procedures to
measure trace amounts of DNA. The assay is relatively easy to perform,  measures
DNA in a range of one to one hundred  picograms,  can detect small  fragments of
DNA, and is complete in about three hours.  As reported in the Company's  10-KSB
filed in April 1998, prior to its preliminary launch of the Program Assay in the
third quarter of 1997,  the Company had  eliminated a step in the Picogram Assay
which was  intended  to make the assay more user  friendly.  Subsequent  to this
preliminary  launch,  it was suspected that the  elimination of this step caused
the assay to lose some  reproducibility  in the  ultra-sensitive  lower limit of
measurability.  Accordingly,  management of the Company felt that it was prudent
to temporarily  remove the product from the market until the product's  original
reproducibility could be restored.  Accordingly,  the Picogram Assay was removed
from the  marketplace  in December,  1997.  However,  through the  redevelopment
process the Company  discovered that removal of this step did not cause the loss
of  sensitivity.  Instead,  the Company  discovered  that plastic  tubes holding
certain reagents caused the problem by adherence of a portion of the reagents to
the  inside  of the  tube.  Subsequently,  the  Company  changed  the  tubes and
reintroduced the Picogram Assay to the market in the third quarter of 1998.

         The use of the  Picogram  Assay does not require the  purchase of major
equipment, since the assay utilizes a standard microtiter plate reader, which is
routine in biopharmaceutical quality control laboratories. The assay is designed
for routine  application by technicians  and is intended for validation of final
product purity.

EASYID MICROBIAL IDENTIFICATION TECHNOLOGY

         Genetic  Vectors  is  developing  the EasyID  technology  for the rapid
identification of yeasts and other microbes of commercial and research interest.
The Company's  development  efforts have been affected by the Company's  working
capital  shortage.  EasyID  technology  is based on a series of small DNA chains
known as DNA probes. DNA probes are used in gene detection techniques to clearly
identify specific genes. DNA probes also have a common day-to-day application in
the  identification  of  microbes,   usually  in  health-  or   research-related
applications.  Basic EasyID kits will provide DNA probes that should allow clear
identification  of yeast species or strains by detecting a gene possessed solely
by that  species or strain.  The Company  intends to join its EpiDNA  technology
with its EasyID  technology to produce labeled probes.  Genetic Vectors believes
that its EasyID kits  should  give users a rapid means for yeast  identification
because  results  should  normally be  obtained in about two hours.  The Company
believes  that  these  assays can be  refined  to run in about  fifteen  minutes

                                       4

<PAGE>

similar to other DNA probe tests.  This is a major improvement over conventional
culture-based  identification techniques,  which often take days to complete and
are sometimes inaccurate.

         A  commercial  antibody-based  test for yeast is  available,  but costs
about $15 per test.  Genetic  Vectors  believes  that its  EasyID DNA probe will
allow accurate identification of yeast species and strains, at a lower cost than
existing products and much more rapidly than conventional techniques.

         One market for these probes is in quality control in the manufacture of
wines. Wineries depend on proprietary yeast strains for the production of a high
quality product. The Company believes that wine producers are not currently able
to specifically  identify wine yeast strains with  conventional  microbiological
techniques.  The Company  believes that its probes will provide the producers of
wine with a dependable and rapid means to identify their proprietary strains and
to detect  contaminating  yeast  during  the  fermentation  process  and  during
storage.

         Many food and beverage manufacturers have problems with spoilage caused
by yeast contamination of their products.  Conventional  culture-based detection
methods are not  well-suited to quality control in this area because of the time
required for results.  Genetic Vectors believes that the EasyID  technology will
allow the  development  of a series  of tests  that will  detect  yeast  strains
commonly  found as  contaminants  of foods and beverages.  The Company  believes
these assays can be used as a sensitive and rapid quality control mechanism.

RESEARCH AND DEVELOPMENT

         The   Company   spent   approximately    $918,401   and   $805,711   on
Company-sponsored  research and development  activities during its 1998 and 1997
fiscal   years,   respectively.   The  Company  did  not  conduct  any  material
customer-sponsored  research and development  activities  during either of those
fiscal years.

MARKETING AND SALES

         The Company temporarily removed the Picogram Assay from the marketplace
in  December,  1997,  and  reintroduced  it in the third  quarter  of 1998.  The
Company's  marketing  activities in connection  with the  reintroduction  of the
Picogram  Assay  were  limited  by  the  Company's   working  capital  shortage.
Accordingly,  the Company remains  largely a development  stage company with the
Company's expenditures far exceeding its revenues.


         Genetic Vectors intends to use EpiDNA and EasyID  technology to fashion
diagnostic  tools for use in quality control and quality  assurance  programs in
the food and beverage  industry  but there can be no assurance  that this can be
accomplished successfully or at all.

         The  Company  has  received  conflicting   information   regarding  the
potential  market for its Picogram Assay.  Such  information  indicates that the
potential  annual  market for the  Picogram  Assay  ranges  from  $4,000,000  to
$20,000,000. If the actual market for this product is near the lower end of this
range,  the Company will have substantial  difficulty in generating  significant
sales.

REGULATION

         The Company's  operations  will be subject to federal,  state and local
regulations  to  which  business  operations  are  normally  subject,  including
occupational safety and health acts, workmen compensation statutes, unemployment
insurance,  and  income  tax  and  social  security  related  regulations.   The
biotechnology  industry is also subject to federal,  state and local regulations
with  regard  to the  construction,  maintenance,  containment  and  release  of
genetically engineered organisms and the manufacturing of diagnostic devices for
human  use.  The  Company  currently  has  no  plans  to  construct  or  release
genetically  altered organisms or to produce  diagnostic  devices for human use,
and  accordingly  the Company does not anticipate  that these  regulations  will
affect it or its operations.

         The Company's  operations  will be subject to applicable  environmental
laws and  regulations.  The  Company's  operations  will  entail the storage and
disposal of small amounts of biological and chemical hazardous wastes. The costs
that the  Company  has  incurred  to date in  connection  with  compliance  with
environmental  laws and  regulations  have not been  material,  and the  Company
anticipates  that such costs will not be  material  in the  foreseeable  future.
There can be no assurance, however, that this will be the case. The Company does
not anticipate that any significant capital  expenditures  related to compliance
with environmental laws will be required in the foreseeable future.

         Diagnostic and therapeutic  devices and tests that are intended for use
in humans generally require direct FDA approval.  Devices and tests not intended
for use in humans,  however,  are generally not required to obtain FDA approval.
The FDA can also set  industry-wide  required  tests and  approvals.  All of the
Company's  current and  proposed  products are  designed  either for  industrial
quality control or for research purposes and are, therefore,  not subject to FDA
approval.  For example,  the  Company's  EasyID  products are not subject to FDA
approval because they focus on the determination of particular species of yeasts
and fungi in connection with brewing industry applications.

MANUFACTURING

         The  Company's  research  and  development  and  executive  offices are
located at 5201 N.W. 77th Avenue,  Suite 100, Miami,  Florida. In addition,  the
Company relies on outside  vendors to  manufacture  all of the components of its
EpiDNA Picogram Assay.

         Certain key  components  of the  Company's  Picogram  Assay product are
currently  provided by a limited  number of  sources,  and many  components  are
provided by outside vendors.  One component is provided by a single source.  The
Company is utilizing  contract  manufacturers to manufacture  required reagents.
Two key components of the EpiDNA  Picogram  Assay Kit, the  "GeNuncTM"  reaction
modules and the  "MaxisorpTM"  immunomodules  are manufactured by NUNC (a Danish
entity), but can also be obtained from United States distributors such as Fisher
Scientific,  V.W.R. or Baxter Scientific.  The "AmpakTM" detection system, which
is also a key component of the Picogram  Assay,  is available only from a single
source  of  supply.   Additionally,   the  Company   contracts   with  Fujirebio
Diagnostics, Inc. for manufacturing of certain reagents, assembly and packaging.

STRATEGY FOR GROWTH

         In the event the Company is able to raise additional  capital,  Genetic
Vectors intends to expand its business opportunities through increased marketing
efforts (as  outlined in  "Marketing  and Sales") and by  expanding  its product
lines (as described in other  sections).  The Company intends to attempt to form
strategic  alliances with corporate  partners that can provide  distribution for
the  Company's  products or research and  development  support for its long term
research and development activities. The Company's labeling, detection and assay
kits may  provide an  attractive  means for a  strategic  partner to enhance its
existing product lines. The Company may also seek to license or sublicense those
applications  of the Technology that are either outside its product focus or for
which funding is inadequate.

         Additionally,  the Company  believes that there are favorable  business
acquisition  opportunities  that  would  enable it to expand its  business  more
rapidly.  To  date,  the  Company  has been  unsuccessful  in  consummating  any
acquisitions  and has expended  approximately  $152,000 in pursuing  acquisition
opportunities.  Management believes that the successful  consummation of several
of these  acquisition  opportunities  would  enable it to achieve  economies  of
scale, improve gross margins and increase revenues and/or market share. However,
the Company's  ability to pursue or  consummate  any  acquisition  is completely
dependent on its ability to obtain significant  additional  capital.  Generally,
shareholder approval will not be required in connection with such activities.

COMPETITION

         The  biotechnology  industry  is subject to  intense  competition.  The
Company's  competitors in the United States and internationally are numerous and
include,   among   others,   diagnostics,   health  care,   pharmaceutical   and
biotechnology  companies.   Additionally,   other  companies,   including  large
biotechnology  companies,  may  enter  the  Company's  business  in the  future.
Potential  competitors may be able to develop technologies that are as effective
as, or more  effective or easier to interpret than those offered by the Company,
which would render the Company's products noncompetitive or obsolete.  Moreover,
many of the Company's  existing and  potential  competitors  have  substantially
greater financial,  marketing,  sales,  distribution and technological resources
than the  Company.  Such  existing  and  potential  competitors  may also  enjoy
substantial  advantages  over the Company in terms of research  and  development
expertise,  experience in conducting  clinical trials,  experience in regulatory
matters,   manufacturing  efficiency,  name  recognition,  sales  and  marketing
expertise and distribution channels.  There can be no assurance that the Company
will be able to compete  successfully  against current or future  competitors or
that  competition  will not have a  material  adverse  effect  on the  Company's
business, financial condition and results of operations.

         Genetic  Vectors'  chosen area of  business  lies in the  labeling  and
detection  of  nucleic  acids  using the  Technology.  The  Company  has  chosen
specifically to market products that are not currently subject to regulation and
that can be marketed  without the  requirement  for  obtaining or licensing  any
additional  technology.  The market which the Company  intends to serve includes
tests for quality control of  biopharmaceutical  drug production and in food and
fermented beverages.  In addition, the Company intends to market its products to
the life science  research  community.  These widely diverse markets result in a
wide variety of competitive situations.

         DNA CONTAMINATION ASSAYS IN  BIOPHARMACEUTICALS.  Several companies are
currently  involved  in  making  or  selling  trace DNA  detection  reagents  or
equipment,  or  performing  assays.  In  this  market  there  are two  types  of
competitors:  (1)  instrument  and reagent  sellers and (2) specialty  reference
labs.  Genetic  Vectors  believes  that the largest  competitive  element in the
current market is specialty reference laboratories. These reference laboratories
offer DNA  assaying  at their  own  facilities  based on their own  individually
developed  assays.  While clearly  competitors,  the Company believes that these
facilities also represent potential customers for its products.

CUSTOMERS

         The   Company's   customers   to  date  have   been   biopharmaceutical
manufacturers.  To date,  the Company has not generated  significant  sales and,
therefore, is not dependent on any customers.

EMPLOYEES

         Genetic  Vectors  currently  has  seven  employees,  two of  which  are
executive officers and all of which are full-time  employees.  See "Management's
Plan of  Operation  and  Discussion  and  Analysis  - Changes  in the  Number of
Employees."  None  of  the  Company's  employees  are  covered  by a  collective
bargaining  agreement  and the  Company  believes  its  employee  relations  are
satisfactory.

INTELLECTUAL PROPERTY RIGHTS

         The Company has acquired rights to make, use and sell certain  products
under the  patents  and patent  applications  referred  to herein  pursuant to a
License Agreement dated September 7, 1990 between ProVec,  Inc.,  ("ProVec"),  a
company owned by Dr. Mead McCabe,  and the University of Miami and its School of
Medicine,  the owner of the patents and patent  applications.  The University of
Miami acquired the rights by virtue of an employee  agreement and the University
Patent Policy. Parts of the invention were made using funds of the United States
Government.  On January 20, 1992,  ProVec  assigned its rights under the License
Agreement  to EpiDNA,  Inc., a wholly owned  subsidiary  of the Company.  EpiDNA
merged into the Company on September 6, 1996.

         The  license  granted  under the License  Agreement  is  worldwide  and
exclusive  (except  for the  rights of the  Federal  Government)  providing  the
Company  with the right to  manufacture,  use and sell  products  utilizing  the
patents  and  patent  applications  referred  to  herein.  The  Company  has the
obligation, at its own expense, to prosecute and maintain patents in the name of
or on behalf of the  University of Miami.  Further,  the Company is obligated to
maintain product liability  insurance,  with the University of Miami being named
as an  additional  insured.  The  License  Agreement  provides  for payment of a
maintenance  fee of $500 and a running  royalty  of 4% of net sales of  products
using the  Technology.  The  maintenance  fee is  creditable  against  royalties
subsequently due in a given year. The term of the License  Agreement is the life
of the U.S. patent and/or its foreign counterpart patents. The License Agreement
can be terminated by the University of Miami,  at its  discretion,  for material
breaches  by the  Company.  Primary  among  such  breaches  are  failure to file
quarterly reports of sales, nonpayment of royalties, failure to develop and sell
products  based on the  Technology,  cessation  of sales  for a period  of three
months and bankruptcy or adjudication of insolvency.  A two-month cure period is

                                       8

provided for correction of breaches.  If the License  Agreement is terminated by
the  University of Miami,  the ownership of the patents and patent  applications
and all rights to develop,  manufacture  and sell products under the patents and
patent  applications will revert to the University of Miami and the Company will
be unable to produce, market or sell products whose manufacture,  use or sale is
covered by the claims of the patents and patent applications referred to herein.
Thus,  the  Company  would  suffer a material  adverse  effect on its  business,
financial  condition and viability if the  University  of Miami  terminated  the
License Agreement.

         Since the patents and patent applications referred to herein were made,
in part,  using  federal  funds  provided  by a  federal  agency,  the  National
Institute of Health ("NIH") has a  nonexclusive,  nontransferable,  irrevocable,
paid-up  worldwide  license to practice the  invention  (35 U.S.C.  202 (c)(4)).
Under  this   nonexclusive   license,   the  NIH  can  use  the   Technology  in
federally-funded  projects  or it can,  if  provided  in a treaty or  agreement,
sublicense the Technology to a foreign government or international organization.
This nonexclusive license to the NIH did not terminate with the licensing of the
Technology  to the  Company.  The NIH also has  certain  rights (35 U.S.C.  203)
allowing  it to  grant  licenses  to  third  parties  if it is  determined  that
practical  application  of  the  invention  is  not  occurring,  even  exclusive
licenses,  as well as march-in  rights to meet unmet health or safety needs,  to
meet requirements for public use specified in federal regulations or for failure
to  manufacture  in the United States or to obtain a waiver of such  provisions.
The grant of an exclusive  license or the exercise of the march-in  rights would
cause the Company to suffer a material adverse effect on its business, financial
condition and viability.  As described herein, the Company has already developed
products based on the  Technology and intends to continue the  commercialization
of the Technology.

         The  Company  has  applied  for and  been  granted,  on  behalf  of the
University of Miami,  patent protection for part of the Technology in the United
States and other countries. Letters Patent Number 246228 has been issued for the
Technology in New Zealand.  Also, the University of Miami,  at Company  expense,
has filed for and was granted patents under the International Patent Cooperation
Treaty,  followed by national  stage filings in  Australia,  New Zealand and the
European  Patent  Office.  There are currently two United States patents for the
Technology.

CERTAIN BUSINESS RISK FACTORS

         The  Company  is subject  to  various  risks  which may have a material
adverse effect on its business,  financial  condition and results of operations.
Certain risks are discussed below.

         FUTURE CAPITAL NEEDS AND UNCERTAINTY OF ADDITIONAL FUNDING. The Company
had cash and cash  equivalents  of only $156,054 as of December 31, 1998.  Since
November 1998, the Company  borrowed a total of $438,500 from private  investors
in four  separate  transactions.  The Company  projects  that such funds will be
completely  exhausted  on or before  the end of April  1999.  In the  absence of
additional  capital,  the Company will be required to  significantly  curtail or
cease its business activities.  The Company has no commitment for any additional
capital and no  assurance  can be given that the Company will be  successful  in
obtaining any additional capital. The Company's ability to continue its business
activities is completely dependent on such additional capital and its failure to
obtain  such  capital  will have a  material  adverse  effect  on the  Company's
business,  financial  condition and results of operation and will jeopardize the
Company's ability to continue its business activities.

                                       9

<PAGE>

         ABILITY TO REPAY SECURED INDEBTEDNESS.  In order to fund its operations
since  November  1998,  the  Company  was forced to borrow  money  from  private
investors  in five  separate  transactions.  See "Plan of Operation - Additional
Fund  Raising   Activities."   Three  of  these   transactions  are  secured  by
substantially  all of the Company's  assets.  The Company's ability to repay all
such loans is completely  dependent on the Company's ability to raise additional
capital from external  sources.  The Company's  failure to raise such capital by
the repayment date of these loans may result in the foreclosure on the Company's
assets.  This would have a material  adverse  effect on the Company's  business,
financial condition and results of operations and would jeopardize the Company's
ability to continue its business activities.

         LIMITED OPERATING HISTORY AND EXPECTATION OF FUTURE LOSSES. The Company
was organized in 1991 and since inception has been in the development  stage. To
date,  the Company has  generated  very  limited  revenues  from the sale of its
product.  Further,  the  Company  has  devoted  most of its  efforts  to various
organizational   activities,   including   research  and   development  and  the
development  of a business  strategy.  From its inception  through  December 31,
1998, the Company has incurred  cumulative losses of approximately $6.1 million.
The Company expects to incur substantial  losses for the foreseeable future due,
in part, to research and  development,  distributing  and marketing its product.
There can be no assurance that the Company will not encounter substantial delays
and  unexpected  expenses  related  to  research,  development,  production  and
marketing or other unforeseen difficulties, which may cause additional losses.

         UNCERTAIN  MARKET  ACCEPTANCE  AND  DEPENDENCE  ON A LIMITED  NUMBER OF
PRODUCTS. The Company currently has one product, the Picogram Assay, and another
product line under development, the EasyID product line. As such, the Company is
highly  dependent on a limited  number of products and the  Company's  long-term
success may depend on the market acceptance of these products. Market acceptance
of the  Company's  products will depend,  in part,  on the Company's  ability to
demonstrate the superiority of its products with respect to existing techniques,
including   the   products'   accuracy,    ease   of   use,    reliability   and
cost-effectiveness  and on the effectiveness of the Company's marketing efforts.
These  efforts have been  adversely  affected by the Company's  working  capital
shortage. No assurance can be given that the Company will gain market acceptance
for its products.  Failure to gain market acceptance for either of these product
lines will have a material adverse effect on the Company's  business,  financial
condition and results of operations.

         TECHNOLOGICAL  UNCERTAINTY AND EARLY STAGE OF PRODUCT DEVELOPMENT.  The
science and  technology  of the Program  Assay and EasyID are rapidly  evolving.
Although the Company has  conducted  limited  marketing of its initial  product,
other proposed products are in the early development  stage. These products will
require significant further research, development and testing and are subject to
the risks of failure inherent in the development of products based on innovative
technologies.  These  risks  include  the  possibility  that  any  or all of the
proposed  products are found to be  ineffective,  unsafe,  or otherwise  fail to
receive necessary  regulatory  clearances,  if any, that the proposed  products,
though  effective,   are  uneconomical  to  market,   that  third  parties  hold
proprietary  rights that preclude the Company from marketing them, or that third
parties  market a superior or equivalent  product.  Accordingly,  the Company is
unable to predict whether its research and development activities will result in
any commercially viable products.

                                       10

<PAGE>

         LIMITED   MANUFACTURING   AND  MARKETING   CAPABILITY.   The  Company's
experience in manufacturing  has been limited to the production of small amounts
of kits of its initial  product for use in research  and  development  and early
commercialization  of its initial  product.  No assurance  can be given that the
Company will  ultimately be able to obtain or produce  sufficient  quantities of
such product at commercially reasonable costs.

         The Company  has limited  experience  in  marketing  its product and no
assurance exists that the Company can market its product in an effective manner.
The Company intends to market its product in the United States,  Europe and Asia
through a network of independent distributors supported by a direct sales force,
but no sales force is yet in place,  and no  distribution  agreements  have been
entered into. The Company's ability to market its product in Europe and Asia and
other areas will depend on the Company's ability to fund such efforts as well as
the Company's  ability to develop strategic  alliances with marketing  partners.
There can be no assurance  that the Company will enter into such  alliances with
other companies on favorable terms or at all.

         RISK OF PRODUCT LIABILITY CLAIMS.  The nature of the Company's business
exposes it to risk from product liability claims.  The Company maintains product
liability  insurance for its products  with limits of $1 million per  occurrence
and $2 million in the aggregate per year.  Such insurance  coverage is, however,
becoming increasingly expensive and there can be no assurance that the Company's
insurance will be adequate to cover future product liability claims, or that the
Company will be successful in maintaining  adequate product liability  insurance
at acceptable rates. In addition, due to the Company's working capital shortage,
there can be no assurance that the Company will be able to fund the premiums for
its  existing  insurance.  Any losses  that the  Company  may suffer from future
liability claims,  and any adverse publicity from product liability  litigation,
may  have a  material  adverse  effect  on  the  Company's  business,  financial
condition and results of operations.

         UNCERTAINTY  REGARDING  PATENTS AND PROPRIETARY  RIGHTS.  The Company's
success  will  depend in part on its  ability  to  obtain  and  maintain  patent
protection  for its products,  preserve its trade secrets,  and operate  without
infringing the proprietary  rights of other parties.  Because of the substantial
length  of time and  expense  associated  with  bringing  new  products  through
development to the marketplace,  the biotechnology  industry places considerable
importance on obtaining and maintaining  patent and trade secret  protection for
new technologies,  products and processes. Legal standards relating to the scope
of claims and the validity of patents in the  biotechnology  field are uncertain
and evolving.  There can be no assurance that patent  applications  to which the
Company  holds rights will result in the  issuance of patents,  that any patents
issued or licensed to the Company will not be challenged and held to be invalid,
or that any such patents will provide commercially significant protection to the
Company's  technology,  products and  processes.  In  addition,  there can be no
assurance that others will not independently  develop  substantially  equivalent
proprietary  information  not covered by patents to which the Company has rights
or obtain  access to the  Company's  know-how  or that others will not be issued
patents which may prevent the sale of one or more of the Company's products,  or
require  licensing  and the  payment of  significant  fees or  royalties  by the
Company to third parties in order to enable the Company to conduct its business.
Defense and  prosecution  of patent claims can be expensive and time  consuming,
regardless of whether the outcome is favorable to the Company, and can result in
the diversion of substantial financial, management, and other resources from the
Company's  other  activities.  An adverse  outcome  could subject the Company to

                                       11

<PAGE>

significant  liability to third parties,  require the Company to obtain licenses
from third  parties,  or require the Company to cease any related  research  and
development  activities  or  product  sales.  In  addition,  the laws of certain
countries may not protect the Company's  intellectual property. No assurance can
be given  that any  licenses  required  under any such  third-party  patents  or
proprietary rights would be made available on commercially  reasonable terms, if
at all. In addition, due to the Company's working capital shortage, there can be
no  assurance  that the Company  will be able to continue  its  existing  patent
applications.

         The Company's success is also dependent upon the skills, knowledge, and
experience  of its  scientific  and  technical  personnel.  To help  protect its
rights, the Company plans to require all of its employees, consultants, advisors
and  collaborators  to enter into  confidentiality  agreements that prohibit the
disclosure of confidential information to anyone outside the Company and require
disclosure  and  in  most  cases  assignment  to the  Company  of  their  ideas,
developments,  discoveries and inventions.  There can be no assurance,  however,
that these agreements will provide  adequate  protection for the Company's trade
secrets,  know-how  or  other  proprietary  information  in  the  event  of  any
unauthorized use or disclosure.

         DEPENDENCE ON KEY PERSONNEL;  INEXPERIENCE OF MANAGEMENT. The Company's
ability  to  successfully  manage its growth  will  substantially  depend on its
ability to attract and retain additional qualified management personnel. Because
of the  Company's  cash  shortage,  its  ability to attract or retain  qualified
personnel  has been  hindered.  This cash shortage has caused the Company to pay
only  one-half of its  employees'  salaries  during  portions of December  1998,
January 1999, February 1999, April 1999, and for all of March 1999. On April 23,
1998,  the Company  paid the  unpaid  salary for some if its  employees  for the
period from  December  1998  through  April 16, 1999.  On December 9, 1998,  the
Company issued the employees options to purchase an aggregate of 4,393 shares of
Common Stock at an exercise price of $5.00 per share or approximately $2.25 less
than the closing  price on that date.  The Company  recently  repurchased  1,171
options  from its  employees  for an  aggregate  purchase  price of $2,635.  The
Company is currently  accruing one-half of its employees  salaries which it will
pay when and if  additional  capital is  received.  The Company  also intends to
issue additional stock options to its non-executive  employees for March 1999 at
a price to be determined.  Currently, none of the Company's administrative staff
has any experience in running a large company or a company whose  securities are
publicly  held,  apart  from the  Company.  There can be no  assurance  that the
demands  placed on Company  personnel by the cash  shortage or the growth of the
Company's business and the need for close monitoring of the Company's operations
and financial  performance through  appropriate and reliable  administrative and
accounting  procedures  and  controls  will be met,  or that  the  Company  will
otherwise  manage its  growth  successfully;  the  failure to do so could have a
material  adverse  affect on the Company's  business,  results of operations and
financial condition.  There is significant  competition for qualified personnel,
and there can be no assurance that the Company will be successful in recruiting,
retaining or training  the  management  personnel  it requires.  The Company has
designated Mead M. McCabe, Jr. as its interim principal  financial officer.  The
Company  currently has no officer with  experience in managing the financial and
accounting functions of a publicly-held company.

ITEM 2.           DESCRIPTION OF PROPERTY.
- ------------------------------------------

         The Company currently leases approximately 14,000 square feet of office
space located at 5201 N.W. 77th Avenue,  Suite 100, Miami,  Florida 33166.  This
lease,  which was  entered  into on June 12,  1997,  has a ten-year  term.  This
property is in good condition.

DIVIDENDS

         The Company has not paid any dividends on its Common Stock at any time.
Section 607.06401 of Florida Statutes  prohibits the payment of dividends by any
corporation  which after taking into account such dividend  would not be able to
pay its debts as they  become due or which  would  result in such  corporation's
total assets being less than its total liabilities.  This provision may prohibit
the Company from paying  dividends  unless the Company  obtains  significant new
capital. Other than the foregoing,  the Company is not aware of any restrictions
on its  ability  to pay  dividends  on  its  Common  Stock,  but  the  Company's
management does not anticipate paying any dividends for the foreseeable future.

SALES OF UNREGISTERED SECURITIES

         In June and August of 1998,  the  Company  issued an  aggregate  of 709
shares in  exchange  for  consulting  services  valued by the Company at $6,000,
based on the closing  price on the date of grant.  This Offering was exempt from
registration  pursuant to Section 4(2) of the Securities Act of 1933, as amended
(the "Act").

         On September 8, 1998, the Company  granted  warrants to purchase 50,000
shares of Common Stock of the Company at an exercise price of $6.00 per share to
a  consultant  (the  "Consultant")  to assist the  Company to obtain  additional
financing. These warrants are immediately exercisable.  The closing price of the
Company's Common Stock on September 8, 1998 was $9.125. This offering was exempt
from registration pursuant to Section 4(2) of the Act.

         On November 2, 1998,  the Company  borrowed  $150,000  from two private
investors  ("Loan  No.  1").  The  terms of Loan No. 1  provided  for an  annual
interest  rate of 12% which will  increase 1% for each month that any portion of
Loan No. 1 remains  unpaid after April 1, 1999, up to the maximum rate permitted
by law.  Accrued  interest is payable  monthly  beginning on April 1, 1999.  The
outstanding  principal  must be repaid by  November 2, 1999.  The  Company  also
issued to the private  investors  warrants to purchase  15,000  shares of Common
Stock at an exercise  price of $6.00 per share.  These warrants may be exercised
at any time before  November 2, 2003.  The closing  price of the Common Stock on
November  2, 1998 was $7.00.  The  Company  is  obligated  to grant the  private
investors  warrants to purchase an additional 1,250 shares of Common Stock at an
exercise  price of $6.00 per share on April 1,  1999 and each  month  thereafter
through  October 1, 1999 until the loans are repaid in full. On November 1, 1999
and each  month  thereafter  that the  loans are  outstanding,  the  Company  is
obligated  to grant the private  investors  warrants  to purchase an  additional
2,500  shares of Common  Stock at an exercise  price of $6.00.  The  proceeds of
these  loans have been used by the Company to fund its  working  capital  needs.
This offering was exempt from  registration  pursuant to Section 4(2) of the Act
and Rule 506 promulgated thereunder.

         In  addition  and on  November  2,  1998,  the  Company  issued  to the
Consultant  warrants to purchase  15,000  shares of Common  Stock at an exercise
price of $6.00 per share. These warrants are immediately exercisable.
This offering was exempt from registration pursuant to Section 4(2) of the Act.


         On January 19,  1999,  the  Company  borrowed  $163,500  from a private
investor ("Loan No. 2"). The terms of Loan No. 2 provided for an annual interest
rate of 12% which will  increase  1% for each month that any portion of the loan

                                       14

<PAGE>

remains  unpaid after January 19, 2000, up to the maximum rate permitted by law.
Accrued interest is payable monthly beginning on April 19, 1999. The outstanding
principal  balance  must be repaid by January 19,  2000.  The loan is secured by
substantially all of the Company's  assets. In addition,  the Company issued the
private  investor  warrants  to  purchase  50,000  shares of Common  Stock at an
exercise price of $0.01 per share.  These warrants are immediately  exercisable.
The  closing  price of the Common  Stock on January  19,  1999 was  $5.125.  The
Company is obligated to grant the private investor  warrants to purchase 150,000
shares at an exercise price of $5.50 per share upon the repayment of the loan or
the  closing  on the  sale of  Company  securities  in an  aggregate  amount  of
$1,500,000. Such additional warrants become exercisable on the fifth anniversary
of the grant.  The  proceeds  of this loan have  already  been  expended  by the
Company to fund its  working  capital  needs.  This  offering  was  exempt  form
registration  pursuant  to  Section  4(2) of the Act and  Rule  506  promulgated
thereunder.

         On March 9, 1999, the Company  borrowed an additional  $125,000  ("Loan
No. 3") from the same private  investor  which had made Loan No. 2. The terms of
Loan No. 3 provided for an annual  interest  rate of 12% which will  increase 1%
for each month that any portion of the loan  remains  unpaid  after  January 19,
2000,  up to the maximum  rate  permitted  by law.  Accrued  interest is payable
monthly  beginning on April 19, 1999. The outstanding  principal balance must be
repaid by January  19,  2000.  The loan is secured by  substantially  all of the
Company's assets. In addition,  the Company issued the private investor warrants
to purchase  50,000  shares of Common  Stock at an  exercise  price of $0.01 per
share.  These  warrants are  immediately  exercisable.  The closing price of the
Common Stock on March 9, 1999 was $7.875.  Substantially  all of the proceeds of
this loan have been expended by the Company to fund its working  capital  needs.
This offering was exempt from  registration  pursuant to Section 4(2) of the Act
and Rule 506 promulgated thereunder.

         In  connection  with  Loan No. 2 and Loan No.  3, the  Company  granted
warrants  to  purchase  16,350  shares of Common  Stock on January  19, 1999 and
12,500 shares of Common Stock on March 9, 1999 at an exercise price of $5.50 per
share to the Consultant  for helping the Company to locate the financing.  These
warrants are immediately exercisable.  The closing price of the Common Stock was
$5.125 and  $7.875 on January  19,  1999 and March 9, 1999,  respectively.  This
offering was exempt from registration pursuant to Section 4(2) of the Act.

         On April 19, 1999, the Company  borrowed an additional  $100,000 ("Loan
No. 4") from a private  investor.  This loan has an annual interest rate of 12%.
Accrued interest is payable  quarterly,  commencing on June 1, 1999. The loan is
secured by substantially all of the Company's  assets. In addition,  the Company
issued the private  investor  warrants to purchase 25,000 shares of Common Stock
at an  exercise  price  of $3.50  per  share.  These  warrants  are  immediately
exercisable.  The closing price of the Common Stock on April 19, 1999 was $6.00.
The Company  intends to use these proceeds on unpaid  salaries for its employees
and for other working capital purposes. The Company believes that these proceeds
will last for less than one month.  This  offering was exempt from  registration
pursuant to Section 4(2) of the Act and Rule 506 promulgated thereunder.

INTRODUCTORY STATEMENTS


         FORWARD-LOOKING  STATEMENTS  AND ASSOCIATED  RISKS.  This Annual Report
contains forward-looking statements, including statements regarding, among other
things,  (a) the Company's  growth  strategies,  (b)  anticipated  trends in the
Company's  industry and (c) the Company's  future  financing plans. In addition,
when used in this Annual Report, the words "believes," "anticipates," "intends,"
"in  anticipation  of," and  similar  words are  intended  to  identify  certain
forward-looking  statements.  These forward-looking statements are based largely

                                       17

<PAGE>

on the  Company's  expectations  and  are  subject  to a  number  of  risks  and
uncertainties,  many of which are beyond the Company's  control.  Actual results
could differ  materially  from these  forward-looking  statements as a result of
changes in trends in the economy and the Company's  industry,  reductions in the
availability  of  financing  and  other  factors.  In light of these  risks  and
uncertainties,  there can be no assurance  that the  forward-looking  statements
contained  in this  Annual  Report  will in fact  occur.  The  Company  does not
undertake  any  obligation  to publicly  release the results of any revisions to
these  forward-looking  statements that may be made to reflect any future events
or circumstances.

         The Company temporarily removed the Picogram Assay from the marketplace
in December,  1997 and subsequently  re-launched it in the third quarter of 1998
but has not generated  significant sales revenue.  The Company remains largely a
development  stage company,  with the Company's  expenditures  far exceeding its
revenues.  Because the  Company  has not  generated  significant  revenues,  the
Company intends to continue to report its plan of operation.

PLAN OF OPERATION

         ADDITIONAL  FUND  RAISING   ACTIVITIES.   The  Company  had  originally
projected  that the funds  raised in its initial  public  offering  (the "IPO"),
which was closed on December 26,  1996,  would last for  approximately  eighteen
months after the date of the Offering. As previously reported in its Form 10-QSB
for the three-month period ended September 30, 1998, the Company needed to raise
additional capital to continue operations beyond November 1998. In order to fund
its operations since November 1998, the Company had to borrow money from several
private  investors in four separate  transactions.  These loan transactions were
intended to provide short-term financing to the Company. The aggregate amount of
these loans (excluding payments of commissions and other expenses) was $438,500.
The Company  anticipates that these loan proceeds will be completely expended by
the end of April  1999.  Thereafter,  the  Company's  ability  to  continue  its
business  activities  will be completely  dependent on its ability to obtain new
capital.  The  Company  has no  commitment  for any  additional  capital  and no
assurances  can be given that the Company will be  successful in raising any new
capital. A summary of these loan transactions is contained in "Market for Common
Equity and Related Stockholder  Matters - Sales of Unregistered  Securities." In
the absence of additional capital, the Company will be required to significantly
curtail or cease its business activities.

         The plan of operation  described in this Annual Report assumes that the
Company will be successful in raising  significant  additional  capital,  but no
assurances  can be given that the  Company  will be  successful  in raising  any
additional  capital.  The failure to raise additional  capital will, among other
things,  cause  significant  deviations from the plan of operation  described in
this Annual  Report,  and will have a material  adverse  effect on the Company's
business, financial condition and results of operations. It will also jeopardize
the Company's ability to continue its business activities.

         SUMMARY OF ANTICIPATED  PRODUCT RESEARCH AND  DEVELOPMENT.  The Company
intends to  continue  its  product  research  and  development  and  continue to
implement  what  the  Company  believes  to  be  a  feasible  plan  for  product
development.  The Company has modified its feasibility  plan since the filing of
its Quarterly  Report on Form 10-QSB for the three-month  period ended September
30,  1998.  The Company  expects to employ its  resources  in the  research  and

                                       18

<PAGE>

development of potential  applications of its nucleic acid labeling  technology.
The major components of the plan of operation as revised from the last reporting
period are as follows:

1999     o     Continued development of applications of Genetic Vectors' nucleic
               acid labeling technology.


         o     Development of EasyID DNA probe products for quality assurance in
               the food and beverage industry.

2000     o     Development of EasyID probe products for quality assurance in the
               food and beverage industry.

         o     Continued development of applications of Genetic Vectors' nucleic
               acid labeling technology.

         SIGNIFICANT  PLANT OR  EQUIPMENT  PURCHASES.  The  Company  anticipates
purchasing or leasing  equipment valued at approximately  $250,000 in 1999 to be
used in connection with the foregoing development plan.

         CHANGES IN THE NUMBER OF  EMPLOYEES.  The Company  currently  has seven
employees.  As shown in the  following  chart,  the Company  anticipates  hiring
additional  personnel  during 1999 and 2000 in connection  with its research and
development  and  product  development  plan.  The Company  believes  that these
personnel will be adequate to accomplish the tasks set forth in its plan.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

         The Company  generated  revenues  of $11,275  during  1998,  which were
attributable  to the launch of the  Picogram  Assay.  In  addition,  the Company
recognized  $35,897 in grant revenue  during 1998.  During 1997, the Company was
awarded  a grant for  $99,897  from the  National  Institute  of Health  and the

                                       19

<PAGE>

National Institute of Allergy and Infectious  Diseases for rapid  identification
of fungal species.  In this  connection,  the Company  recognized  grant revenue
aggregating  $35,897  and  $64,000  in 1998 and  1997,  respectively.  The award
terminated on February 27, 1998.

         The sales  generated  by the Company  during 1998 were  preliminary  in
nature, and represented the purchase of product samples primarily for evaluation
purposes.  The Company  reintroduced  the Picogram Assay in the third quarter of
1998;  however,  the Company  remains  largely a development  stage company with
expenditures far exceeding revenues.

         Research and development  expenses for 1998 increased by $179,226.  The
increase was largely  attributable to accelerated product improvement efforts on
EpiDNA  Picogram  Assay  kits  and  development  efforts  on the  core  labeling
technology. In addition, the Company created a new research and development cost
center  which the  Company  believes  resulted  in better  tracking  of  certain
research and  development  expenses.  Some of these  expenses had not previously
been  classified  as research  and  development  expenses,  including  certain
salaries.  This  reclassification  resulted in greater  research and development
expenses in 1998 compared to 1997.

         Operating  expenses  for 1998 were  approximately  the same as in 1997,
increasing only $584.

         Interest income for 1998 decreased by $136,970  because the Company had
less cash invested during 1998 than in 1997. Interest income was attributable to
interest  earned on  certificates  of deposit and money  market  accounts  which
represented the investment of the net proceeds of the Company's IPO and proceeds
from the issuance of debentures.

         LIQUIDITY AND CAPITAL RESOURCES. The Company had net cash of $2,102,467
at the beginning of 1998,  consisting  primarily of the net proceeds received by
the Company in the IPO. The net cash used by the Company in operating activities
aggregated $2,125,437. This was largely attributable to research and development
and  general  and  administrative  expenses.  The  Company's  net  cash  used in
investing  activities  aggregated  $64,606  during  1998,  consisting  mainly of
purchases of laboratory and office equipment.

         As of December 31, 1998, the Company had total stockholders'  equity of
$563,575 and had short-term  debt of $150,000.  The Company had $109,924 in cash
and cash  equivalents as of December 31, 1998. This  represents,  in large part,
the  proceeds  from  Loan No. 1. The  Company  anticipates  that such  proceeds,
together  with  the net  proceeds  from  Loan No.  2 and  Loan  No.  3,  will be
completely  expended by the end of April 1999.  Thereafter,  the Company will be
required  to  significantly  curtail  or cease  its  business  activities  until
additional  capital  can be  obtained,  if at  all.  See  "Plan  of  Operation."
Additional  financing  is  necessary  for the Company to continue  its  business
activities. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Going Concern Opinion."

         As discussed throughout this Annual Report, the Company has experienced
extreme cash  shortages  since the end of November 1998 through the date of this
Annual Report. See "Plan of Operation - Additional Fund Raising  Activities." As
a result of these cash  shortages,  the Company was  required to pay one-half of
its  employees'  salaries in cash and one-half in stock options for a portion of
December  1998 and January  1999.  On December 9, 1998,  the Company  issued the
employees options to purchase an aggregate of 4,393 shares of Common Stock at an
exercise price of $5.00 per share or  approximately  $2.25 less than the closing
price on that date.  In addition,  the Company was required to pay only one-half
of its  employees'  salaries  in cash for all of March 1999 in order to preserve
cash.  The Company is currently  accruing  one-half of its  employees'  salaries
which it will pay when and if additional capital is received.  In addition,  the

                                       20

Company will issue additional stock options to its non-executive  employees at a
price to be determined.

         YEAR 2000 COMPUTER ISSUES. Computer programs have typically abbreviated
dates by eliminating  the first two digits of the year under the assumption that
these two digits would be 19. As the year 2000 approaches, these systems may not
be able to recognize  current dates which may cause  computer  system failure or
miscalculations by computer  programs.  The Company does not believe it will not
be  materially  affected by the Year 2000 problem.  The Company's  conclusion is
based on a survey of the computer equipment currently in use by the Company. All
such  equipment  was  acquired by the Company  within the last two years and was
Year-2000-compliant  when  acquired.  The  Company  has not  expended a material
amount of costs in this  assessment.  Moreover,  the Company  remains  largely a
research and  development  company and  therefore  its exposure to the Year 2000
problems of its  customers  and  suppliers is minimal.  However,  the Company is
exposed to the risk that one or more of its suppliers could experience Year 2000
problems  that may impact their ability to supply  materials to the Company.  To
date,  the Company is not aware of any Year 2000 problems of its suppliers  that
would have a material adverse impact on the Company's  operations.  Nonetheless,
the inability of suppliers to convert their  computer  systems to avoid any Year
2000  problems  could  jeopardize  the supply of  materials  to the  Company and
therefore have a material adverse effect on the Company's operations. The effect
of  non-compliance  by suppliers is not determinable at this time. The Company's
Year 2000 risks are considered  minimal and no contingency plans are believed to
be necessary.  As a result,  the Company believes the potential  consequences of
Year-2000 problems will not have a material effect on the Company.

         IMPACT OF INFLATION.  Although inflation has slowed in recent years, it
is still a factor in the United States economy and the Company continues to seek
ways to mitigate its impact. To the extent permitted by competition, the Company
intends to pass increased  costs on to its customers by increasing  sales prices
over time. In addition,  the Company places all of its major supplier  purchases
out to bid.

         NEW  FASB  PRONOUNCEMENTS.  In  June  1998,  the  Financial  Accounting
Standards  Board issued SFAS 133,  "Accounting  for Derivative  Instruments  and
Hedging  Activities."  SFAS 133 requires  companies to recognize all derivatives
contracts as either  assets or  liabilities  in the balance sheet and to measure
them at  fair  value.  If  certain  conditions  are  met,  a  derivative  may be
specifically  designated  as a hedge,  the  objective  of which is to match  the
timing  of  gain  or  loss  recognition  on  the  hedging  derivative  with  the
recognition  of (i) the  changes  in the  fair  value  of the  hedged  asset  or
liability that are  attributable  to the hedged risk or (ii) the earnings effect
of the hedged  forecasted  transaction.  For a derivative  not  designated  as a
hedging  instrument,  the gain or loss is recognized in operations in the period
of  change.  SFAS 133 is  effective  for all  fiscal  quarters  of fiscal  years
beginning after June 15, 1999.

         Historically,  the Company has not entered into  derivatives  contracts
either to hedge existing risks or for  speculative  purposes.  Accordingly,  the
Company  does not  expect  adoption  of the new  standard  on January 1, 2000 to
affect its financial statements.

                              date have  largely  consisted  of the research and
                              development  of its  products.  The Company had no
                              financial  activities  from  December  28, 1991 to
                              December  31, 1991.  Accordingly,  January 1, 1992
                              has  been  used as the  inception  date  of  these
                              financial statements.

                              These    financial    statements    include    the
                              specifically  identifiable expenses of the Company
                              incurred by Nyer on behalf of the Company.

                              Nyer,   which   previously   owned  74.9%  of  the
                              Company's   common  stock,   distributed   to  its
                              shareholders  512,000 shares,  representing 32% of
                              the  outstanding  shares of the  Company's  common
                              stock as of May 31, 1996.

                              -----------------------------------

                              The   preparation   of  financial   statements  in
                              conformity  with  generally  accepted   accounting
                              principles  requires  management to make estimates
                              and assumptions  that affect the reported  amounts
                              of  assets  and   liabilities  and  disclosure  of
                              contingent  assets and  liabilities at the date of
                              the financial  statements and the reported amounts
                              of  revenues  and  expenses  during the  reporting
                              period.  Actual  results  could  differ from those
                              estimates.

                              Deferred  loan  costs  are  carried  at cost  less
                              accumulated amortization. Amortization is computed
                              using the  straight-line  method  over the life of

                              cost less accumulated  amortization.  Amortization

                              Revenue
                              -------

                              The  Company  recognizes  revenue  from sales upon
                              delivery of the product to a customer.

                              During  1997 the  Company  was awarded a grant for
                              $99,897 from the National  Institute of Health and
                              the National  Institute of Allergy and  Infectious
                              Diseases  for  rapid   identification   of  fungal
                              species.  The award  terminated  on  February  27,
                              1998. In this connection,  the Company  recognized
                              grant revenue  aggregating $35,897 and $64,000 for
                              1998 and 1997, respectively.

                              Income Taxes
                              ------------

                              Income taxes are accounted for using the liability
                              approach  under the  provisions  of  Statement  of
                              Financial    Accounting    Standards    No.   109,
                              "Accounting for Income Taxes."

                              The Company filed a consolidated income tax return
                              with  its   parent   through   March   25,   1996.
                              Thereafter, it filed on a separate company basis.

                              -------------------------

                              Net loss per common share is calculated  according
                              to Statement of Financial Accounting Standards No.

                              common shares outstanding during the year.

                              The Company's  potential issuable shares of common
                              stock  pursuant  to  outstanding   stock  purchase
                              options  and  warrants   are  excluded   from  the

                              would be antidilutive to the Company's net loss.

                              -----------------------------------

                              The  Company's   financial   instruments   consist
                              principally   of  cash   and   cash   equivalents,
                              receivables,  accounts  payable and notes payable.
                              The carrying amounts of such financial instruments
                              as  reflected  in the  balance  sheet  approximate
                              their  estimated  fair  value as of  December  31,
                              1998. The estimated fair value is not  necessarily
                              indicative   of  the  amounts  the  Company  could
                              realize in a current market  exchange or of future
                              earnings or cash flows.

                              Comprehensive Income
                              --------------------

                              During  1998,  the  Company  adopted  SFAS No. 130
                              "Reporting  Comprehensive  Income."  SFAS No.  130
                              establishes standards for reporting and display of
                              comprehensive    income,    its   components   and
                              accumulated  balances.   Comprehensive  income  is
                              defined to include  all  changes in equity  except
                              those  resulting  from  investments  by owners and
                              distributions to owners.  Among other disclosures,
                              SFAS No.  130  requires  that all  items  that are
                              required to be recognized under current accounting
                              standards as components of comprehensive income be
                              reported   in  a  financial   statement   that  is
                              displayed  with  the  same   prominence  as  other
                              financial statements.

                              The  adoption  of SFAS  No.  130 did not  have any
                              effect on the Company's  financial  statements for
                              the year ended December 31, 1998.

                              SEGMENT REPORTING

                              During  1998,  the  Company  adopted  SFAS No. 131
                              "Disclosures  about  Segments of an Enterprise and
                              Related Information." SFAS No. 131 supersedes SFAS
                              No. 14,  "Financial  Reporting  for  Segments of a
                              Business  Enterprise,"  and establishes  standards
                              for the way public  companies  report  information
                              about  operating   segments  in  annual  financial
                              statements  and  requires  reporting  of  selected
                              information  about  operating  segments in interim
                              financial statements issued to the public. It also
                              establishes  standards for  disclosures  regarding
                              products and services,  geographic areas and major
                              customers. SFAS No. 131 defines operating segments
                              as components  of a company  about which  separate
                              financial   information   is  available   that  is
                              evaluated   regularly   by  the  chief   operating
                              decision   maker  in  deciding   how  to  allocate
                              resources and in assessing performance.

                              The  Company  currently  operates  solely  in  one
                              segment,  the  biopharmaceutical   industry,   and
                              therefore  the  adoption  of SFAS No.  131 did not
                              have  any  effect  on  the   Company's   financial
                              statements for the year ended December 31, 1998.

                              --------------------------------

                              In June 1998, the Financial  Accounting  Standards
                              Board issued SFAS 133,  "Accounting for Derivative
                              Instruments  and  Hedging  Activities."  SFAS  133
                              requires  companies to recognize  all  derivatives

                                                   NOTES TO FINANCIAL STATEMENTS
                                                                     (UNAUDITED)

                              in operations in the period of change. SFAS 133 is
                              effective for all fiscal  quarters of fiscal years
                              beginning after June 15, 1999.

                              Historically,  the Company  has not  entered  into
                              derivatives  contracts  either  to hedge  existing
                              risks or for  speculative  purposes.  Accordingly,
                              the  Company  does not expect  adoption of the new
                              standard   on   January  1,  2000  to  affect  its
                              financial statements.

2.      LIQUIDITY             The  accompanying  financial  statements have been
                              prepared  assuming the Company will  continue as a
                              going   concern.    This   basis   of   accounting
                              contemplates  the recovery of the Company's assets
                              and the  satisfaction  of its  liabilities  in the
                              normal course of operations.  Since inception, the
                              Company  has been  involved  in the  research  and
                              design  of  its  product,  the  development  of an
                              organizational infrastructure, and the performance
                              of   preliminary    marketing   and    promotional
                              activities.  The  Company's  ultimate  ability  to
                              attain  profitable  operations  is dependent  upon
                              obtaining   additional   financing   adequate   to
                              complete  its  development   activities,   and  to
                              achieve a level of sales  adequate  to support its
                              cost  structure.  Through  December 31, 1998,  the
                              Company incurred losses totaling $6,113,445,  used
                              cash from  operating  activities  in the amount of
                              $5,242,360  and  has  been  unable  to  develop  a
                              customer   base  for  its  product   which  raises
                              substantial  doubt about the Company's  ability to
                              continue as a going concern.

                              Subsequent  to  December  31,  1998,  the  Company
                              obtained  $288,500 in  financing  (Note 11).  This
                              amount   has  been   substantially   used  in  the
                              operations  of the Company.  If the Company is not
                              successful  in  obtaining   additional  funds,  it
                              intends  to  cease  operations.  There  can  be no
                              assurance  that the Company will be  successful in
                              consummating  its plans,  or that such  plans,  if
                              consummated,  will  enable  the  Company to attain
                              profitable  operations  or  continue  as  a  going
                              concern.

                              $50,000,   respectively.   These  unsecured  notes

                              connection    with    obtaining   the   financing,
                              respectively.  The  fair  value  of such  warrants
                              amounting  to  $111,150  was  estimated  using the

                              $5,843,000.  The  NOL  expires  during  the  years
                              2007-2013.  In the event of a change in  ownership
                              of  the  Company,   the  utilization  of  the  NOL
                              carryforward  will be subject to limitation  under
                              certain provisions of the Internal Revenue Code.

                              1998,  resulting from the  utilization of the NOL,
                              is not likely;  accordingly, a valuation allowance
                              has been  established  for the full amount of such
                              asset.

                              rights to meet unmet health or safety  needs.  The
                              grant of an exclusive license,  or the exercise of
                              march-in rights, would cause the Company to suffer
                              a  material   adverse   effect  on  its  business,
                              financial condition and viability.

                           b) In  1994, the  Company  entered  into an agreement
                              with an  investment  firm  whereby the  investment
                              firm assisted the Company in obtaining $135,000 in
                              funding through its parent.  In consideration  for
                              these  services,  the  Company  will  pay  to  the
                              investment  firm 5% of sales until five years from
                              the  date  of the  agreement  have  passed  or the
                              cumulative   payments  total  $50,000,   whichever
                              occurs  first.  During  1997,  the  agreement  was
                              assigned to a firm  affiliated  with the Company's
                              underwriter.   No  payments   were  made   through
                              December 31, 1998.

                           c) In   August  1996,  the   Company  entered  into a
                              three year employment  agreement with the Chairman
                              of  the  Board  for a  base  salary  of  $125,000.
                              Pursuant to the agreement, the Company granted ten
                              year  options  vesting  over a three year  period,
                              exercisable  during the period of  employment,  to
                              purchase  100,000  shares  of  common  stock at an
                              exercise price equal to 120% of the initial public
                              offering price per share of common stock.

                          d)  The  Company  entered  into  a  new  lease  during
                              June 1997 for office  and  laboratory  space.  The
                              facility is leased for a ten year term with annual
                              rental  payments  of  approximately  $192,000  and
                              annual  increases of 3%. In December of 1998,  the
                              Company  renegotiated  the lease  reducing  annual
                              rental  payments  to  approximately  $164,000  and
                              annual  increases of 3%. Rent expense for 1998 and
                              1997   aggregated   approximately   $192,300   and

                              After  five  years the  Company  has the option to
                              cancel its lease agreement for a cancellation  fee
                              equal to three months of the then monthly rent.

                              In  1997,   a  director   received   approximately
                              $109,000  for  consulting  services in  connection
                              with   the   identification   of   the   facility,
                              negotiation  of the lease and design,  engineering
                              and construction management services.

                           f) In September 1998, in connection  with the signing
                              of   the    consulting    agreement    to   obtain
                              approximately  $3,000,000  in  financing  for  the
                              Company,  a  consultant  to the Company was issued
                              50,000   warrants  to   purchase   shares  of  the
                              Company's  common  stock at $6.00 per  share.  The
                              Company  estimated  the fair value of the warrants
                              at the  grant  date  by  using  the  Black-Scholes
                              option    pricing   model   with   the   following
                              weighted-average  assumptions:  no dividend  yield
                              percent;  expected  volatility  of 0.488 risk free
                              interest rate of 5.03%,  and an estimated  life of
                              10 years.  The fair value of  services  related to
                              1998 of $332,500 was charged to operations  during
                              the period ended December 31, 1998.

                              accounting  for the plan.  Under APB  Opinion  25,
                              because  the  exercise   price  of  the  Company's
                              employee  stock  options  equals  or  exceeds  the
                              market price of the  underlying  stock on the date
                              of grant, no compensation cost is recognized.

                              In August 1996,  the Company  adopted an Incentive
                              Plan (the "Plan")  under which  300,000  shares of
                              common  stock  are  reserved   for issuance   upon
                              exercise   of  stock   based   awards   including,
                              non-qualified   stock  options,   incentive  stock
                              options, stock appreciation rights or for issuance
                              of  restricted  shares  of  common  stock or other
                              stock-based awards. The Plan is also authorized to
                              issue short-term cash incentive  awards.  The Plan
                              is currently  administered by a plan administrator
                              which consists of the Board of Directors,  but may
                              consist  of  such   committees,   officers  and/or
                              employees  of  the  Company  as the  Board  may so
                              designate.  The  purchase  price of each  share of
                              common stock purchased upon exercise of any option
                              granted is as follows:  i) Incentive stock options
                              shall be equal to or greater  than the fair market
                              value of the common  stock on the date of grant as
                              required under Section 422 of the Internal Revenue
                              Code,  ii)  Options  granted  to 10%  holders  and
                              designated by the Plan  Administrator as Incentive
                              Stock  Options  shall be equal to or greater  than
                              110% of the fair market  value of the common stock
                              on the date of grant as required under Section 422
                              of the Internal Revenue Code,  (iii)  Non-employee
                              director options shall be equal to or greater than
                              the fair market  value of the common  stock on the
                              date of the grant.

                              FASB  Statement 123,  Accounting  for  Stock-Based
                              Compensation,  requires the Company to provide pro

non-employee  directors  (Mr.  Burroughs and Dr. Fell) have an exercise price of
$12.00 per share (120% of the offering price in the Company's  IPO).  Options to
purchase  5,000  shares of Common  Stock were  granted to Mr.  Michael  Foley on
January  12,  1998 (the date he joined the Board of  Directors)  at an  exercise
price of $7.75.  Options  granted in the  future  will be priced at no less than
100% of the Common  Stock's fair market value on the date of the grant.  Options
granted to non-employee  directors will be non-statutory options and will become
exercisable  after one year of service on the Board and will be exercisable  for
ten years from the date of the grant,  except that  options  exercisable  at the
time of a director's death may be exercised for twelve months thereafter.  Under
the  terms  of the  Incentive  Plan,  neither  the  Board of  Directors  nor any
committee of the Board of  Directors  will have any  discretion  with respect to
options granted to directors.

Employment Agreements

         Effective August 15, 1996, the Company entered into written  employment
agreements (the "Employment  Agreements")  with Dr. McCabe and Mr. McCabe for an
initial three year period.  Both individuals  devote  substantially all of their
time to the business of the Company.  Dr.  McCabe's  base salary is $125,000 per
year and Mr.  McCabe's  base  salary is $75,000  per year.  Pursuant  to a Stock
Option Addendum to Dr. McCabe and Mr. McCabe's Employment Agreements, Dr. McCabe
and Mr.  McCabe  were  granted  options to purchase  100,000 and 75,000  shares,
respectively,  of the Common  Stock at $12.00  per share  (120% of the per share
public offering price in the Company's initial public  offering).  These options
vest over a three year period,  expire ten years after the date of the grant and
are granted  under and are subject to the terms and  conditions of the Incentive
Plan and Stock Option  Addendum.  The  provisions  of the Stock Option  Addendum
shall control in the event of the  termination  of either of these  individuals'
employment with the Company.  The Employment  Agreements provide that during the
employee's period of employment and in the event of a termination for cause, for
two years after  termination,  the employee will not participate in any business
that is  competitive  with that of the Company in any location where the Company
is doing business as of the date of  termination  of the employee's  employment.
This non-competition covenant will not apply in the event of Dr. McCabe's or Mr.
McCabe's resignation.

Incentive Plan

         Overview of the Incentive Plan

         Incentive compensation for non-employee directors, executives and other
key employees of the Company will be provided  under the Genetic  Vectors,  Inc.
1996  Incentive  Plan.  The purpose of the Incentive Plan is to (a) increase the
proprietary and vested interest of non-employee  directors of the Company in the
growth and  performance  of the Company,  (b) assist in attracting and retaining
highly  competent  employees,  (c) provide an incentive for motivating  selected
officers and other key employees of the Company, (d) achieve long-term corporate
objectives and (e) enable cash incentive awards to qualify as  performance-based
for  purposes  of the tax  deduction  limitations  under  Section  162(m) of the
Internal Revenue Code of 1986, as amended.


                                       52
<PAGE>


         The  Incentive  Plan is  administered  by the Board of Directors of the
Company or such  committees,  officers  and/or  employees  of the Company as the
Board of Directors may so designate.  Eligible participants include non-employee
directors  and such  officers and other key employees of the Company as the plan
administrator  may designate from time to time. The Incentive Plan will continue
in  effect  until  terminated  by its  terms  or,  if  earlier,  by the Board of
Directors.

         The Incentive Plan  authorizes the plan  administrator  to grant any or
all of the following types of awards: (1) stock options, including non-qualified
stock options and incentive stock options,  (2) stock  appreciation  rights, (3)
restricted shares of Common Stock, (4) performance awards, (5) other stock-based
awards, and (6) short-term cash incentive awards.

         Administration

         The Incentive Plan is  administered by a plan  administrator,  which is
currently  the  Compensation  Committee  of the  Board  of  Directors.  The plan
administrator has been granted exclusive and final authority under the Incentive
Plan with  respect  to all  determinations,  interpretations  and other  actions
affecting the Incentive Plan and its participants.

         Shares Subject to the Incentive Plan

         Three hundred  thousand shares of the Company's  Common Stock have been
initially  authorized to be issued under the  Incentive  Plan.  Such  authorized
shares will be  appropriately  adjusted to reflect  adjustments  (if any) to the
Company's capital structure.

Indemnification of Officers and Directors


         Pursuant to authority  conferred by Florida law, the Company's  By-laws
provide that the Company's directors,  officers, and employees be indemnified to
the fullest  extent  permitted by Florida law.  Insofar as  indemnification  for
liabilities  arising under the Securities Act may be permitted for directors and
officers and  controlling  persons  pursuant to the  foregoing  provisions,  the
Company has been  advised  that in the opinion of the  Securities  and  Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act and is, therefore, unenforceable.

     ownership of any other  person.  The Common  Stock is the only  outstanding
     class of equity securities of the Company.

ITEM 12.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.
- -----------------------------------------------------------------

PAYMENT FOR REAL ESTATE CONSULTING SERVICES

         The Company paid approximately  $109,000 to Mark E. Burroughs, a member
of the Board of Directors,  in 1997. This payment was made to Mr.  Burroughs for
his  services  in  connection  with  the  identification  of a  facility,  lease
negotiations and design,  engineering and construction  management  services for
the Company's new facility.

CONSULTING AGREEMENT

         On June 19, 1996 the Company  entered into a consulting  agreement with
Mr. James A. Joyce,  who became a director of the Company on August 13, 1996. He
was granted options to purchase a total of 75,000 shares of the Company's Common
Stock at an  exercise  price of $5.00  per  share,  all of which  are  currently
exercisable.  These  options were not issued  through the Incentive  Plan.  This
agreement terminated in December 1996. Mr. Joyce continued to provide consulting


                                       55
<PAGE>


services  through June 1997. Mr. Joyce's  option  exercise  rights will continue
until the fourth anniversary of the execution of such consulting agreement.

ROLE OF MEAD M. MCCABE, SR.

         Dr.  McCabe has been  involved in the  Company's  operations  since its
inception but he did not serve as a traditional  "promoter" of the Company. As a
scientist,  his role  since the  Company's  inception  has been  focused  on the
technical aspects of the Technology rather than the traditional  promoter's role
of attempting  to build the Company and promote its success.  Dr. McCabe was the
developer of the nucleic acid  labeling and  detection  Technology  which is the
basis for the  Company's  products.  He was the sole  owner of ProVec,  Inc.,  a
company which was the original licensee of the Technology and which subsequently
assigned  its license  rights to the  Company.  Though the Company was formed in
1991, he did not receive any shares of its Common Stock until 1996. At that time
he received 20% of the Company's  Common Stock in exchange for all of the shares
of the Class B Preferred  Stock of Nyer  Medical  owned by him and his wife.  In
1996,  he received an  additional  11,322 shares of Common Stock in exchange for
the conversion of certain  indebtedness owed to him by the Company in connection
with accrued payroll and expenses.

OBLIGATIONS UNDER INVESTORS FINDERS AGREEMENT

         In June 1994,  the Company and Nyer  Medical  entered into an Investors
Finders  Agreement with an investment firm pursuant to which the investment firm
assisted the Company in obtaining approximately $135,000 in funding through Nyer
Medical. The Agreement requires the Company to pay the investment firm 5% of its
gross sales revenues until five years from the date of the Agreement have passed
or the cumulative payments total $50,000,  whichever comes first. This agreement
has been assigned to Shamrock  Partners  International  Inc., a firm  affiliated
with the underwriter who managed the Offering.

TRANSACTIONS WITH OFFICERS AND SHAREHOLDERS

         The  Company  believes  that all  transactions  entered  into  with its
officers and  shareholders  have been  effected on terms and  conditions no less
favorable to the Company than those available from  unaffiliated  third parties.
The  Company  anticipates  that any  future  transactions  with such  affiliated
parties will be made on terms and  conditions  no less  favorable to the Company
than those available from unaffiliated third parties.

                          COMMON STOCK PURCHASE WARRANT

        GENETIC VECTORS,  INC., a Florida  corporation  (the "COMPANY"),  hereby
certifies that, for value received,  PATRICIA A. GIANONE (the "HOLDER"),  or her
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 2,, 2003,  Five Thousand  (5,000) shares of fully paid
and  non-assessable  shares of the $0.001 par value per share  common stock (the
"COMMON  STOCK") of the  Company,  at a purchase  price per share of $6.00 (such
purchase  price per share as adjusted  from time to time as  provided  herein is
referred to herein as the  "PURCHASE  PRICE").  The number and character of such
shares of Common  Stock and the  Purchase  Price 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,  $0.001
par value per share,  as  authorized  on the date of the Agreement 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 then in
effect.


                                       
<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 Subscription Form by (b) the Purchase Price then
in effect. 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,  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,  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.  In case at any time or from time to time,
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. The Company shall grant to the Holder additional
warrants to purchase  additional shares of Common Stock, in the amount set forth
in the following table, commencing on April 1, 1999 and on the first day of each
month  thereafter,  PROVIDED  that the Company shall have no obligation to grant
additional  warrants  if on or before the date on which such grant is to be made
by the Company no amounts are outstanding on that certain Promissory Note in the
original principal amount of $100,000 given by the Company to the Holder:

                                                       NO. OF SHARES
        DATE:                                          OF COMMON STOCK:
        ----                                           --------------- 
        April 1, 1999 through October 1, 1999          1,250

        November 1, 1999 and thereafter                2,500

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.

        5. RIGHT TO ATTEND  BOARD  MEETINGS.  The Holder shall have the right to
have a single  representative  present (either in person or by telephone) at all
meetings of the Board of  Directors of the Company for so long as any portion of
the Note  remains  unpaid.  Such  representative  shall  not be  deemed  to be a
director and shall have no voting rights.

        6.  NO DILUTION OR IMPAIRMENT.

            (a)  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
Warrants,  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  holders  of the  Warrants
against dilution or other impairment.

            (b)  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 the  difference  between  the  Purchase
Price and $1.00.  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


                                       3
<PAGE>


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.

        7.  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  issue or grant by the  Company  of any  shares of
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 the conversion of the Notes
and the exercise of the Warrants),  then and in each such event the Company will
mail or cause to be  mailed  to each  registered  holder  of a  Warrant 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 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 20 days  prior to the date  specified  in such  notice  on which  any such
action is to be taken.

         8.  CERTAIN DELIVERIES. The Company shall deliver to the Holder copies
of  all  documents  filed  by the  Company  with  the  Securities  and  Exchange
Commission.  In  addition  and for so long as any  portion  of the Note  remains
unpaid,  the Company shall deliver to the Holder copies of its monthly financial
statements.  Such  financial  statements  shall be  delivered  on or before  the
thirtieth day of each month for the immediately preceding month.

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

                          -----------------------------

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "Company"),  hereby
certifies that, for value received, the JEROME P. SEIDEN IRREVOCABLE TRUST DATED

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

upon the order of the holder hereof a new Warrant or Warrants of like tenor,  in

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.  In case at any time or from  time to  time,  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.  The Company shall grant to the Holder additional
warrants to purchase  additional shares of Common Stock, in the amount set forth
in the following table, commencing on April 1, 1999 and on the first day of each
month  thereafter,  PROVIDED  that the Company shall have no obligation to grant
additional  warrants  if on or before the date on which such grant is to be made
by the Company no amounts are outstanding on that certain Promissory Note in the
original principal amount of $100,000 given by the Company to the Holder:

                                                  NO. OF SHARES
      DATE:                                       OF COMMON STOCK:
      ----                                        ---------------

      April 1, 1999  through  October 1, 1999     1,250
      
      November 1, 1999 and thereafter             2,500

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.

      5.  RIGHT TO ATTEND BOARD MEETINGS.  The  Holder  shall  have the right to
have a single  representative  present (either in person or by telephone) at all
meetings of the Board of  Directors of the Company for so long as any portion of
the Note  remains  unpaid.  Such  representative  shall  not be  deemed  to be a
director and shall have no voting rights.

      6.  NO DILUTION OR IMPAIRMENT.

          (a)  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
Warrants,  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  holders  of the  Warrants
against dilution or other impairment.

          (b)  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 the  difference  between  the  Purchase
Price and $1.00.  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


                                       3
<PAGE>

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.

      7.  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  issue or grant by the Company of any shares of 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 the conversion of the Notes
and the exercise of the Warrants),  then and in each such event the Company will
mail or cause to be  mailed  to each  registered  holder  of a  Warrant 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 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 20 days  prior to the date  specified  in such  notice  on which  any such
action is to be taken.

      8.  CERTAIN DELIVERIES.  The  Company shall  deliver to the  Holder copies
of  all  documents  filed  by the  Company  with  the  Securities  and  Exchange
Commission.  In  addition  and for so long as any  portion  of the Note  remains
unpaid,  the Company shall deliver to the Holder copies of its monthly financial
statements.  Such  financial  statements  shall be  delivered  on or before  the
thirtieth day of each month for the immediately preceding month.

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
Warrants so surrendered.

      11. REPLACEMENT  OF  WARRANTS.   On   receipt   of   evidence   reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss,  heft or  destruction of any Warrant,
on delivery of an indemnity  agreement or security  reasonably  satisfactory  in
form and  amount  to the  Company  or,  in the case of any such  mutilation,  on
surrender  and  cancellation  of such  warrant,  the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

entire  agreement  among the  parties  and  supersedes  any prior  agreement  or
understanding  among them with respect to the subject matter hereof,  and it may

      THIS WARRANT AND THE  UNDERLYING  SHARES OF COMMON STOCK ISSUABLE UPON ITS
EXERCISE 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

No. W-5

                                    FORM OF
                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "Company"),  hereby
certifies  that, for value received,  STERLING  TECHNOLOGY  PARTNERS,  LTD. (the
"Holder"),  or its registered  permitted  assigns,  is entitled,  subject to the
terms set forth below,  to purchase from the Company at any time Fifty  Thousand
(50,000)  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 $6.00 (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 of the  Agreement  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


<PAGE>

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, 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,  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.  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


                                       2
<PAGE>

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  issue or grant by the Company of any shares of 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),
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

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

      THIS WARRANT AND THE  UNDERLYING  SHARES OF COMMON STOCK ISSUABLE UPON ITS
EXERCISE 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

No. W-4

                                    FORM OF
                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "COMPANY"),  hereby
certifies  that, for value received,  STERLING  TECHNOLOGY  PARTNERS,  LTD. (the
"HOLDER"),  or its registered  permitted  assigns,  is entitled,  subject to the
terms set forth below, to purchase from the Company at any time Sixteen Thousand
Three Hundred and Fifty (16,350) 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 $5.50 (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 of the  Agreement  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


<PAGE>

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, 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, 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.  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


                                       2
<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.

      9.  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

      THIS WARRANT AND THE  UNDERLYING  SHARES OF COMMON STOCK ISSUABLE UPON ITS
EXERCISE 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

REQUIRED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

No. W-7

                                    FORM OF
                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "COMPANY"),  hereby
certifies  that, for value received,  STERLING  TECHNOLOGY  PARTNERS,  LTD. (the
"HOLDER"),  or its registered  permitted  assigns,  is entitled,  subject to the
terms set forth below,  to purchase from the Company at any time Twelve Thousand
Five Hundred (12,500) 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 $5.50  (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


<PAGE>

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, 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,  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.  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


                                       2
<PAGE>

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  issue or grant by the Company of any shares of 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),
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
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.  CERTAIN  DELIVERIES. The Company shall deliver to the Holder copies of
all documents filed by the Company with the Securities and Exchange  Commission.
In  addition  and for so long as any  portion of the Note  remains  unpaid,  the
Company shall deliver to the Holder copies of its monthly financial  statements.
Such financial  statements  shall be delivered on or before the thirtieth day of
each month for the immediately preceding month.

      7.  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 the Warrant,  all shares of Common Stock from time to time  issuable
on the exercise of the Warrant.

<PAGE>

      8.  EXCHANGE OF WARRANT.  On surrender of the Warrant, properly 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 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 Warrants so surrendered.

      9.  REPLACEMENT OF WARRANT. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of the Warrant and,
in the case of any such loss,  theft or destruction of the Warrant,  on delivery
of an indemnity agreement or security reasonably satisfactory in form and amount
to the  Company  or,  in the  case of any  such  mutilation,  on  surrender  and
cancellation  of such  warrant,  the  Company at its  expense  will  execute and
deliver, in lieu thereof, a new Warrant of like tenor.

      10. NEGOTIABILITY. This Warrant is issued upon the following terms, to all
of which each Holder or owner hereof by the taking hereof consents and agrees:

          (a) subject to compliance with all applicable  securities  laws, title
to  this  Warrant  may be  transferred  by  endorsement  (by the  Holder  hereof
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
endorsement and delivery;

          (b) any person in  possession  of this  Warrant  properly  endorsed is
authorized  to  represent  himself as absolute  owner hereof and is empowered to
transfer absolute title hereto by endorsement and delivery hereof to a BONA FIDe
purchaser  hereof for value;  each prior taker or owner waives and renounces all
of his  equities  or  rights  in this  Warrant  in favor of each  such BONA FIDE
purchaser, and each such BONA FIDE purchaser shall acquire absolute title hereto
and to all rights represented hereby; and

          (c) until this Warrant is transferred on the books of the Company, the
Company may treat the registered  Holder hereof as the absolute owner hereof for
all purposes, notwithstanding any notice to the contrary.

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  Agreement  shall be deemed to have
occurred  unless  such waiver is in writing,  signed by the party  against  whom

subsequent breach or condition of a like or different nature.

      14. SEVERABILITY. If any provision of this Agreement shall be held invalid

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


                                       5

the  Company,  that  such  registration  is not  required  under the Act and any

      THIS WARRANT AND THE  UNDERLYING  SHARES OF COMMON STOCK ISSUABLE UPON ITS
EXERCISE 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,  THAT SUCH  REGISTRATION  IS NOT
REQUIRED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

No. W-3

                                    FORM OF
                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "COMPANY"),  hereby
certifies  that,  for  value  received,   CAPITAL   RESEARCH  LTD.,  a  Delaware
corporation (the "HOLDER"),  or its registered  permitted assigns,  is entitled,
subject to the terms set forth below,  to purchase  from the Company at any time
Fifty Thousand (50,000) 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 of the  Agreement  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


<PAGE>

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, 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,  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.

          3.3.  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


                                       2
<PAGE>

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  Fifty-Thousand  (150,000)  shares of fully paid and
non-assessable  Common  Stock at a  purchase  price  per  share  of  $5.50  (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
            $4.00. 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.  RIGHT  TO ATTEND BOARD  MEETINGS.  The Holder shall have  the right to
have a single representative present (either in person or by  telephone)  at all
meetings of the Board of  Directors of the Company for so long as any portion of
the Note  remains  unpaid.  Such  representative  shall  not be  deemed  to be a
director and shall have no voting rights.

      6.  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.

      7.  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  issue or grant by the Company of any shares of 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),
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
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.

      8.  CERTAIN  DELIVERIES. The Company shall deliver to the Holder copies of
all documents filed by the Company with the Securities and Exchange  Commission.
In  addition  and for so long as any  portion of the Note  remains  unpaid,  the
Company shall deliver to the Holder copies of its monthly financial  statements.
Such financial  statements  shall be delivered on or before the thirtieth day of
each month for the immediately preceding month.

      9.  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 the Warrant,  all shares of Common Stock from time to time  issuable
on the exercise of the Warrant.


                                        4
<PAGE>


      10. EXCHANGE OF WARRANT.  On surrender of the Warrant,  properly 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 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 Warrants so surrendered.

      11. REPLACEMENT OF WARRANT. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of the Warrant and,
in the case of any such loss,  theft or destruction of the Warrant,  on delivery
of an indemnity agreement or security reasonably satisfactory in form and amount

Obligations.  

                    (ii) All interest,  dividends, income and other payments and

over to Pledgee;

                    (iii)  notwithstanding  anything  contained  hereto  to  the

receipt of written notice thereof by Pledgor; provided, however, that if Pledgor

such other obligor or their creditors,  the Holder  (irrespective of whether the

the Holder any amounts for expenses due it hereunder.

Holder to  authorize,  consent to or accept or adopt on behalf of any Holder any
plan of  reorganization,  arrangement,  adjustment or composition  affecting the
rights of any Holder  thereof or to  authorize  the Holder to vote in respect of
the claim of any Holder in any such proceeding.

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

      GENETIC  VECTORS,  INC., a Florida  corporation  (the  "Company"),  hereby
certifies  that,  for  value  received,   CAPITAL   RESEARCH  LTD.,  a  Delaware
corporation (the "Holder"),  or its registered  permitted assigns,  is entitled,
subject to the terms set forth below,  to purchase  from the Company at any time
Fifty Thousand (50,000) 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
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


<PAGE>

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, 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,  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.

          3.3.  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


                                       2
<PAGE>

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  Thousand  (100,000)  shares  of  fully  paid  and
non-assessable  Common  Stock at a  purchase  price  per  share  of  $5.50  (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
            $4.00. 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.  RIGHT TO ATTEND BOARD MEETINGS.  The Holder  shall  have  the right to
have a single representative  present (either in person or by  telephone) at all
meetings of the Board of  Directors of the Company for so long as any portion of
the Note  remains  unpaid.  Such  representative  shall  not be  deemed  to be a
director and shall have no voting rights.

      6.  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.

      7.  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

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

of any class or any other  securities,  or any right or option to subscribe for,

securities  (other than this issue of Common Stock on exercise of the  Warrant),
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,

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,

                      FORM OF REGISTRATION RIGHTS AGREEMENT
                      -------------------------------------

      THIS REGISTRATION RIGHTS AGREEMENT (the "AGREEMENT"), dated as of March 9,
1999,  by  and  between  GENETIC  VECTORS,  INC.,  a  Florida  corporation  (the
"COMPANY"),   and  Capital  Research  Ltd.,  a  Delaware  corporation  ("CAPITAL

      The parties hereto, for good and valuable  consideration,  the receipt and
sufficiency of which are hereby acknowledged, and intending to be legally bound,
hereby agree as follows:

      1.  DEFINITIONS.  The following terms have the following meanings:

rules and regulations promulgated thereunder.

          (b) "COMMISSION" means the Securities and Exchange Commission.

          (c) "COMMON STOCK" means the Common Stock, par value $0.001 per share,
of the Company.

          (d)  "REGISTRABLE  SECURITIES"  means any  Warrant  Shares (as defined
herein) held by Capital Research.

          (e) "REGISTRATION," "REGISTER" and like words mean compliance with all
of the laws, rules and regulations (federal, state and local), and provisions of
agreements  and  corporate  documents  pertaining  to  the  public  offering  of
securities,  including  registration of any public offering of securities on any
form under the Act.

          (f) "WARRANT  SHARES"  means any shares of Common Stock of the Company
received by Capital Research in connection with the exercise of the Common Stock
Purchase  Warrant No. W-6 (the  "WARRANT")  of even date  herewith  given by the
Company  to  Capital  Research  or any new  warrant  given to  Capital  Research
pursuant to the terms of such 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,  Capital Research 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 Capital  Research 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 Capital Research 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,  Capital Research 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  Capital
Research 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 Capital  Research 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
Capital Research;  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 Capital  Research 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 Capital  Research in  connection  with
this registration statement. If Capital Research 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,  Capital Research  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 CAPITAL  RESEARCH.   Capital Research
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  Capital

on behalf of  Capital  Research  in  connection  with such  Offering,  including
without limitation, any transfer taxes, underwriting discounts or commissions.
