ITEM 1.  Business.

GENERAL

We were  founded in the early 1970s as a contract  researcher  for the  National
Institutes of Health (NIH). Dr. William A. Carter,  M.D.,  joined the Company in
1976 and  ultimately  become  its CEO in 1988.  He has  focused  the  Company on
exploring,  understanding and mastering the mechanism of nucleic acid technology
to produce a promising new class of drugs for treating  chronic  viral  diseases
and disorders of the immune system.  In the course of almost three  decades,  we
have  established a strong  foundation of laboratory,  pre-clinical and clinical
data with  respect to the  development  of nucleic  acids to enhance the natural
antiviral  defense  system of the human body and the  development of therapeutic
products  for the  treatment  of chronic  diseases.  Our  strategy is to use our
proprietary drug, Ampligen(R), to treat diseases for which adequate treatment is
not available.  We seek the required  regulatory  approvals which will allow the
progressive  introduction of Ampligen(R)  for Myalgic  Encephalomyelitis/Chronic
Fatigue Syndrome ("ME/CFS"), HIV, Hepatitis C ("HCV") and Hepatitis B ("HBV") in
the U.S.,  Canada,


                                       1


Europe and Japan.  Ampligen(R) is currently in phase III clinical  trials in the
U.S. for use in  treatment of ME/CFS and is in Phase IIb clinical  trials in the
U.S. for the treatment of newly emerged  multi-drug  resistant  HIV, and for the
induction of cell mediated immunity in HIV patients that are under control using
potentially toxic drug cocktails.

In March, 2003, the Company acquired from Interferon Sciences Inc. ("ISI"),  all
of ISI's raw  materials,  work-in-progress  and  finished  product  of Alferon N
Injection(R),  together with a limited license for the production,  manufacture,
use, marketing and sale of the product. Alferon N Injection(R) [interferon alfa-
n3 (human  derived)] is a natural alpha interferon that has been approved by the
U.S. Food and Drug Administration  ("FDA") for commercial sale for the treatment
of  certain  types of genital  warts.  We intend to market  this  product in the
United State through sales facilitated via third party marketing agreements.  In
the future, we expect to implement  studies,  beyond those conducted by ISI, for
testing the  potential  treatment  of HIV,  Hepatitis  C and other  indications,
including  multiple  sclerosis.  This acquisition not withstanding,  our primary
focus  remains  the  development  to  Ampligen(R)  for  treating  ME/CFS and HIV
diseases.

In March,  2003, we entered into an agreement with ISI subject to certain events
that would  grant us global  rights to sell  Alferon N  Injection(R)  as well as
acquire  certain  other assets of ISI which  include but are not limited to real
estate and property, plant and equipment.

We outsource certain components of our research and development,  manufacturing,
marketing and  distribution  while  maintaining  control over the entire process
through our quality assurance group and our clinical monitoring group.

                                   AMPLIGEN(R)

Our  proprietary  drug  technology  Ampligen(R)  utilizes  specially  configured
ribonucleic  acid ("RNA") and is  protected  by more than 350 patents  worldwide
with  over  80  additional  patent  applications   pending  to  provide  further
proprietary protection in various international  markets.  Certain patents apply
to the  use of  Ampligen(R)  alone  and  certain  patents  apply  to the  use of
Ampligen(R) in combination with certain other drugs.  Some composition of matter
patents  pertain  to other new  medications  which have a similar  mechanism  of
action.  The main U.S. ME/CFS  treatment patent  (#6130206)  expires January 23,
2015. Our main patents covering HIV treatment (#4795744, #4820696, #5063209, and
#5091374)  expire on August 26,  2006,  September  30,  2008,  August 10,  2010,
respectively;  Hepatitis  treatment coverage is conveyed by U.S. patent #5593973
which expires on October 15, 2014. The U.S. Ampligen(R)  Trademark  (#1,515,099)
expires on December 6, 2008 and can be renewed  thereafter  for an additional 10
years.  The U.S.  FDA has  granted  us  "orphan  drug  status"  for our  nucleic
acid-derived  therapeutics  for  ME/CFS,  HIV,  and  renal  cell  carcinoma  and
malignant  melanoma.  Orphan drug status grants the Company  protection  against
competition  for a period of seven  years  following  FDA  approval,  as well as
certain federal tax incentives, and other regulatory benefits.

Nucleic  acid  compounds  represent  a  potential  new  class of  pharmaceutical
products that are designed to act at the molecular  level for treatment of human
diseases.  There are two forms of nucleic acids,  DNA and RNA. DNA is a group of
naturally  occurring   molecules  found  in  chromosomes,   the  cell's  genetic
machinery.  RNA is a group of naturally occurring  informational molecules which
orchestrate a cell's  behavior and which regulate the action of groups of cells,
including the cells,


                                       2


which comprise the body's immune system.  RNA directs the production of proteins
and regulates  certain cell activities  including the activation of an otherwise
dormant cellular defense against virus and tumors. The Company's drug technology
utilizes  specially  configured  RNA.  Our  double-stranded  RNA  drug  product,
trademarked Ampligen(R),  which is administered intravenously,  is (or has been)
in  human  clinical  development  for  various  disease  indications,  including
treatment for ME/CFS, HIV, renal cell carcinoma and malignant melanoma.  Further
studies are planned in cancer but initiation dates have not been set.

Based on the  result  of  published,  peer  reviewed  pre-clinical  studies  and
clinical trials, we believe that Ampligen(R) may have broad-spectrum  anti-viral
and  anti-cancer  properties.  Over 500 patients  have received  Ampligen(R)  in
clinical trials authorized by the FDA at over twenty clinical trial sites across
the U.S.,  representing  the  administration  of more than 45,000  doses of this
drug.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)

ME/CFS is a debilitating disease that is difficult to diagnose and for which, at
present, there is no cure. People suffering from this illness experience,  among
other symptoms, a constant tiredness, recurring dull headaches, joint and muscle
aches,  a feeling  of  feverishness  and  chills  low grade  fever,  depression,
difficulty in concentrating on tasks, and tender lymph glands.  With progression
of the disease they can become bed-ridden,  lose their jobs and become dependent
upon the state for support and medical care.

ME/CFS  has  been  given  official  recognition  by  the  U.S.  Social  Security
Administration,  and some European  nations,  rendering ME/CFS patients eligible
for disability benefits and heightening  awareness of this debilitating  disease
in  the  medical  community.   Further  scientific  publication  by  independent
academicians  on the  accurate  laboratory  diagnosis  of ME/CFS  appeared  in a
peer-reviewed  journal (American Journal of Medicine) in February 2000. The U.S.
Centers of Disease Control ("CDC") reconfirmed its research commitment to ME/CFS
following an audit by the U.S.  Government  Accounting  Office ("GAO") which was
announced July 28, 1999.

Estimates  of ME/CFS  patient  numbers in the Unites  States range from a low of
500,000  (1995-Centers for Disease Control,  Atlanta, GA) to a high of 1,000,000
(1999-DePaul  University  study).  Estimates of patient  numbers in Europe range
from 600,000 to 2,200,000 as reported in the British  Medical Journal in January
2000. It is believed worldwide patient totals may be as high as ten million.

In  1989,  we  received  FDA  authorization  to  conduct  a Phase  II  study  of
Ampligen(R) for ME/CFS. In 1991, we completed a 24-week, 92 patient, randomized,
placebo-controlled,   double-blinded,  multi-center  trial  of  Ampligen(R)  for
treating patients with ME/CFS.  The results,  published in a peer review journal
in 1994,  suggested enhanced physical  performance,  greater cognitive functions
and improved  ability to perform  daily  living  activities.  Patients  required
reduced   hospitalization  and  medical  care,  while  suffering  little  or  no
significant adverse side effects.  The FDA raised certain issues with respect to
this clinical trial,  which required  further study.  These issues were reviewed
and satisfactorily resolved.

In  February  1993,  Hemispherx  presented  results  of its  Phase  II  study of
Ampligen(R)  for  ME/CFS to a FDA  Advisory  Committee  and these  results  were
published in early 1994 in Clinical Infectious Diseases, a peer reviewed medical
journal,   which


                                       3


emphasizes the understanding and potential treatment of infectious diseases. The
results suggested that patients on Ampligen(R), in contrast to those receiving a
placebo,  showed  significant  improvement in physical capacity as determined by
performance on treadmill  testing.  The  Ampligen(R)  treated patient group also
required less pain medication than did the placebo group.

In late 1998, we were authorized by the FDA to initiate a Phase III multicenter,
placebo-controlled,  randomized,  double  blind  clinical  trial  to  treat  230
patients  with  ME/CFS in the U.S.  The  objective  of this Phase III,  clinical
study,  deemed as Amp 516, is to evaluate the safety and efficacy of Ampligen(R)
as a treatment  for ME/CFS.  As of April 1, 2003 we have engaged the services of
eleven (11) clinical investigators at Medical Centers in California, New Jersey,
Florida,  North Carolina,  Wisconsin,  Nevada,  Illinois and Connecticut.  These
clinical  investigators are medical doctors with special knowledge of ME/CFS who
have  recruited,  prescreened  and enrolled ME/CFS patients for inclusion in the
Phase III Amp 516 ME/CFS  clinical  trial.  This clinical trial now has over 230
ME/CFS  patients  participating.  The  patients  complete a stage I, forty week,
double-blind,  randomized,  placebo-controlled portion of the clinical trial and
then move into the stage II or the open label treatment  portion of the clinical
trial. To date there have been no serious adverse events reported related to the
study medication. Additional ME/CFS patients have been recruited by the clinical
investigators  to, in  effect,  over  enroll the  program.  We expect to have in
excess of the full enrollment in order to compensate for potential patient "drop
outs",  i.e.;  patients that  discontinue  the program  prematurely  for various
reasons.  The  next  stage in our  program  is final  data  collection,  quality
assurance of data to insure its  accuracy and analysis of the data  according to
regulatory guidelines to facilitate filing for commercial approval to sell.

Human Immunodeficiency Virus  (HIV)

About  fifteen  antiviral  drugs  are  currently  approved  by the  FDA  for the
treatment  of HIV  infection.  All  target the  specific  HIV  enzymes,  reverse
transcriptase  ("RT") and protease.  The use of various combinations of three or
more of these  drugs is  often  referred  to as  Highly  Active  Anti-Retroviral
Therapy  ("HAART").  HAART involves the  utilization of several  antiretrovirals
with  different  mechanisms  of action to decrease  viral loads in  HIV-infected
patients.  The goal of these  combination  treatments is to reduce the amount of
HIV in the  body  ("viral  load")  to as low  as  possible.  Treatments  include
different  classes of drugs, but they all work by stopping parts of the virus so
the virus cannot  reproduce.  Experience  has shown that using  combinations  of
drugs from different classes is a more effective strategy than using only one or
two drugs.  HAART has provided dramatic  decreases in morbidity and mortality of
HIV infection.  Reduction of the viral load to  undetectable  levels in patients
with wild type virus (i.e.,  non-drug-resistant virus)is routinely possible with
the appropriate application of HAART. HIV mainly infects important immune system
cells called CD4 cells.  After HIV has infected a CD4 cell, the CD4 cell becomes
damaged and is  eventually  destroyed.  Fewer CD4 cells means more damage to the
immune system and,  ultimately,  results in AIDS.  Originally,  reduction of HIV
loads was seen as possibly allowing the  reconstitution of the immune system and
led to early speculation that HIV might be eliminated by HAART.

Subsequent  experience  has  provided  a more  realistic  view of HAART  and the
realization  that chronic HIV suppression  using HAART, as currently  practiced,
would  require  treatment  for  life  with  resulting   significant   cumulative
toxicities.  The various reverse transcriptase and protease inhibitor drugs that
go into HAART have significantly  reduced the morbidity and mortality  connected


                                       4


with HIV; however there has been a significant cost due to drug toxicity.  It is
estimated  that 50% of HIV deaths are from the  toxicity  of the drugs in HAART.
Current estimates suggest that it would require as many as 60 years of HAART for
elimination of HIV in the infected patient. Thus the toxicity of HAART drugs and
the enormous cost of treatment makes this goal impractical.

Although more potent second  generation drugs are under  development that target
the reverse  transcriptase  and protease  genes as well as new HIV targets,  the
problem of drug toxicities, the complex interactions between these drug classes,
and the likelihood of life-long  therapy will remain a serious drawback to their
usage.

Failure  of  antiretroviral   therapies  over  time  and  the  demonstration  of
resistance have stimulated  intensive  searches for appropriate  combinations of
agents,  or  sequential  use of  different  agents,  that  act  upon the same or
different  viral  targets.  This  situation  has  created  interest  in our drug
technology, which operates by a different mechanism.

We believe that the concept of  Strategic  Therapeutic  Interruption  ("STI") of
HAART  provides a unique  opportunity  to minimize the current  deficiencies  of
HAART  while  retaining  the HIV  suppression  capacities  of HAART.  STI is the
cessation of HAART until HIV again becomes detectable (i.e.,  rebounds) followed
by resumption of HAART with subsequent  suppression of HIV. By re-institution of
HAART,  HIV is suppressed  before it can inflict  damage to the immune system of
the patient.  Based on recent publications (AIDS 2001,15:  E19-27 and AIDS 2001,
15:1359-1368) in peer reviewed medical  literature,  it is expected that in just
30 days after  stopping  HAART  approximately  80% to 90%, of the patients  will
suffer a relapse evidencing  detectable levels of HIV. The Company believes that
Ampligen(R)  combined with the STI (strategic treatment  interruption)  approach
may offer a unique  opportunity to retain HAART's superb ability to suppress HIV
while potentially minimizing its deficiencies.  All present approved drugs block
certain  steps in the life cycles of HIV. None of these drugs address the immune
system,  as  Ampligen(R)  potentially  does,  although  HIV  is an  immune-based
disease.

By using  Ampligen(R)  in  combination  with STI of HAART,  we will undertake to
boost the patients' own immune system's  response to help them control their HIV
when  they  are  off  of  HAART.  The  Company's  minimum  expectation  is  that
Ampligen(R)  has  potential  to lengthen the  HAART-free  time  interval  with a
resultant decrease in HAART-induced toxicities. The ultimate potential, which of
course  requires full clinical  testing to accept or reject the  hypothesis,  is
that Ampligen(R) may potentiate STI of HAART to the point that the cell mediated
immune system will be sufficient to eliminate  requirement for HAART. We plan to
present  the  follow on  clinical  results  of using our  technology  at several
International  AIDS Scientific  Forums in 2003,  including the XVI International
Conference on Antiviral research in Savannah, Georgia in April 2003.

Our AMP 720 HIV Clinical Trial is being conducted with individuals infected with
HIV who are responding  well to HAART at the moment.  Patients in this study are
required to meet minimum immune system  requirements  of CD4 cell levels greater
than 400,  maximum HIV infection  levels of less that 50 copies/ml,  and a HAART
regimen containing at least one anti-viral drug showing therapeutic synergy with
Ampligen(R)  based  on  recently  reported  ex  vivo  studies  in  peer-reviewed
scientific  journals.  All patients are  chronically  HIV infected and will have
been receiving the indicated  HAART regimen prior to starting the STI. The trial
applies strategic  treatment  interruption of HAART based on the hypothesis that
careful


                                       5


management  of HIV rebound  following  STI may have  potential  to result in the
development of protective immune responses to HIV in order to achieve control of
HIV replication. The Company believes that the addition of Ampligen(R), with its
potential immunomodulatory properties, may reasonably achieve this outcome. Half
of the  participants  in the trial are given 400 mg of Ampligen(R)  twice a week
and once they start the STI will  remain  off of HAART  until such time as their
HIV rebounds. The other half of the participants (the control group) are on STI,
but they are given no Ampligen(R)  during the "control"  portion of the clinical
test.

The  targeted  enrollment  in the AMP 720  Clinical  Trial  is 120  HIV-infected
persons  who  meet  the  criteria.  We  expect  to have 60  people  on STI  with
Ampligen(R) and 60 people on STI without Ampligen(R).  Presently,  this study is
approximately  35% enrolled at ten medical  centers  around the U.S. The Company
expects  enrollment  in this  clinical  trial to  accelerate  as we recruit more
investigators  and based on the analysis and  presentation of results in Prague,
Czech Republic,  Barcelona, Spain and Naples, FL (December, 2002). The length of
this  stage of the  trial  will be  determined  by an  analysis  of the  interim
results.

Hepatitis C Virus (HCV)

We  currently  have an informal  arrangement  with the  California  Institute of
Molecular Medicine ("CIMM") to collaborate and assist their efforts to replicate
human Kupffer's cells obtained from HCV infected patients. This proprietary CIMM
approach involves the in vitro growth of hepatic  macrophages  (called Kupffer's
cells) from the failing liver of a patient and  reinfusion of the in vitro grown
Kupffer's  liver  cells into the same  patient.  The ability to grow HCV in long
term culture that would allow the testing of, potential  anti-HCV drugs in vitro
would  permit  us  to  conduct  and  obtain  valuable  research  data  in  using
Ampligen(R)  to treat HCV prior to engaging and clinical  trial.  This would not
raise the question of immunological  incompatibility.  Testing by CIMM indicates
that their process of Kupffers's cell application in vitro is reproducible (>95%
efficacy)  from  individual  patients.  CIMM is also  developing  a process  for
maintaining and propagating Kuffer's cells reproducibly in defined cell cultures
from fine needle liver aspirates from living human  volunteers with potential as
patients with failing liver due to a variety of etiologies.

In January 2001 CIMM filed a notice of Invention with the U.S. patent office. As
a result, a patent titled "Replication of Human Kupffer's cell obtained from HCV
infected patients by Fine Needle Biopsy  Technique" was issued.  This method can
potentially  salvage  critically  needed liver function without major surgery or
aggressive medical intervention.

The immediate and potential market for the Kupffer's maintenance and propagation
techniques will be more than 14,000 people in the U.S.  actively seeking a liver
transplant.  Additional  thousands are  progressing  towards a failing liver and
will soon need  transplantation  or a successful  alternative  method to restore
function. Several hundred thousand who have alcoholic cirrhosis may also benefit
from  the  proprietary  process.   Medical  costs  of  a  liver  transplant  are
approximately  $300,000  and are  far  beyond  the  financial  reserves  of most
families.   Reimbursement  of  these  costs  by  Health  Insurance  carriers  is
problematic at best. We have a 30% equity position in CIMM,  which is located in
California and recently  opened a new  state-of-the-art  research  laboratory in
Ventura, California.

We are also  evaluating  potential  novel clinical  programs which would involve
using  Ampligen(R)  to  treat  both HCV and HIV when  they  coexist  on the same
patient.  We expect to commence these studies in collaboration  with one or more
prospective


                                       6


corporate  partners.  A collaborative  Clinical study in Europe,  in conjunction
with  Laboratorios Del Dr. Esteve S.A., is expected to commence during the first
half of 2003.

We have acquired a series of patents on  Oragen(TM),  potentially  an oral broad
spectrum antiviral,  Immunological  enhancers through a licensing agreement with
Temple  University.  We were granted an exclusive  worldwide license from Temple
for the Oragen(TM)  products.  Pursuant to the arrangement,  we are obligated to
pay royalties of 2% on sales of Oragen(TM),  depending on how much technological
assistance is required of Temple.  We currently pay minimum royalties of $30,000
per year to Temple.  These compounds have been evaluated in various academic and
government  laboratories  for  application  to Chronic  viral and  immunological
disorders. Research and development of Oragen(TM) is on hold at this time.

Other Diseases

An FDA authorized Phase I/II study of Ampligen(R) in cancer  including  patients
with renal cell  carcinoma  was  completed  in 1994.  The  results of this study
indicated  that  patients   receiving  high  doses   (200-500mg)   twice  weekly
experienced an increase in medium survival compared to the low dose group and as
compared to an historical control group. We received  authorization from the FDA
to initiate a phase II study using Ampligen(R) to treat patients with metastatic
renal cell  carcinoma.  Patients with  Metastatic  Melanoma were included in the
Phase I/II study of Ampligen(R) in cancer.  The FDA has authorized us to conduct
a Phase II clinical  trial using  Ampligen(R)  in melanoma.  We do not expect to
devote any significant resources to funding these studies in the near future.

Other Antiviral/Immunologic Treatments

After the terrorist  acts of September 11, 2001 and the resultant  International
concern  for  bio-terrorism   (including   Smallpox),   we  filed  a  regulatory
application  with the FDA for  permission  to conduct a clinical  trial,  in the
event of Smallpox dissemination,  using Ampligen(R) therapy as a treatment. This
proposed study was based on an earlier peer reviewed  laboratory study from Yale
University in Partnership with the U.S.  Military  Command at Fort Detrick,  the
U.S.  Biological  defense  Specialty  Research Center.  The result of this study
indicated Ampligen(R) to be promising in a laboratory model of smallpox.

Based on these and other recent positive  results (see below),  we have retained
FDA regulatory counsel in Wash., D.C., to advise us on a commercialization  path
and to arrange relevant meetings with the FDA.

During the thirty day review period of our Clinical  application  by the FDA, we
became aware of a new ongoing laboratory study of Ampligen(R) in smallpox at the
Riga Medical  Institute in Belgium.  Our Medical  Director  had  authorized  the
Institute to use samples of Ampligen(R)  for Research  purposes only. The result
of this study became  available in the early 2003.  In the interim,  we withdrew
our FDA  application  to review the result of the Belgium study and  incorporate
such data into our  Clinical  study  design and  protocol  before  resubmission.
Positive new results on Ampligen(R) were thereafter  reported by branches of the
U.S.   government  using  animal  models  of  smallpox  and  new  guidelines  on
bio-terrorism  approvals were established which mandated only animal studies for
full commercialization.

                             ALFERON N INJECTION(R)

Interferon  is a group of  proteins  produced  and  secreted  by cells to combat
diseases.  Researchers  have identified four major classes of human  interferon:
alpha,  beta,  gamma and  omega.  The  ALFERON N  Injection  product  contains a
multi-species  form of alpha  interferon.  The worldwide  market for  injectable
alpha  interferon-based  products has experienced rapid growth and various alpha
interferon  injectable  products  are  approved  for  many  major  medical  uses
worldwide.

Alpha  interferons  are  manufactured  commercially  in three  ways:  by genetic
engineering,  by cell culture,  and from human white blood cells.  In the United
States, all three of these types of alpha interferon are approved for commercial
sale. Our Natural Alpha Interferon is produced from human white blood cells.

The potential advantages of Natural Alpha Interferon over recombinant interferon
may be based upon their respective molecular compositions. Natural Interferon is
composed  of  a  family  of  proteins   containing  many  molecular  species  of
interferon. In contrast, recombinant alpha interferon each contain only a single
species.  Researchers  have reported that the various  species of interferon may
have differing  antiviral  activity  depending  upon the type of virus.  Natural
Alpha  Interferon  presents a broad  complement  of  species,  which the Company
believes  may account for its higher  efficacy in  laboratory  studies.  Natural
Alpha Interferon is also glycosylated  (partially covered with sugar molecules).
Such  glycosylation is not present on the currently  marketed  recombinant alpha
interferons.  The Company believes that the absence of glycosylation  may be, in
part, responsible for the production of interferon-neutralizing  antibodies seen
in  patients  treated  with   recombinant   alpha   interferon.   Although  cell
culture-derived  interferon  is also  composed  of multiple  glycosylated  alpha
interferon  species,  the types  and  relative  quantity  of these  species  are
different from the Company's Natural Alpha Interferon.

On October 10, 1989, the FDA approved ALFERON N Injection for the  intralesional
(within  lesions)  treatment of  refractory  (resistant  to other  treatment) or
recurring  external genital warts in patients 18 years of age or older.  Certain
types  of  human  papillomaviruses  ("HPV")  cause  genital  warts,  a  sexually
transmitted  disease ("STD").  A published  report estimates that  approximately
eight  million new and recurrent  causes of genital warts occur  annually in the
United States alone.

Basically, our interest in acquiring Alferon N was driven by two factors;

      1)    our belief  that its use in  combination  with  Ampligen(R)  has the
            potential to increase the positive therapeutic  responses in chronic
            life threatening viral diseases.  Combinational  therapy is evolving
            to the  standard  of  acceptable  medical  care  based on a detailed
            examination  of the  Biochemistry  of the body's  natural  antiviral
            immune response; and

      2)    new knowledge about the competitive products in the Interferon arena
            that we believe  imply a large  untapped  market and  potential  new
            therapeutic  indication  for  Alferon N which could  accelerate  its
            revenues in the near term. Specifically, the recombinant DNA derived
            alpha  interferon  are now reported to have  dramatically  decreased
            effectiveness after one year, probably due to antibody formation and
            other severe  toxicities.  These  detrimental  effects have not been
            reported  with  Alferon N which could allow this product to assume a
            much larger market share.  These revenues would provide  operational
            capital  to  complete   the  Phase  III   Clinical   trials  of  our
            experimental   drug,   Ampligen(R)   in  a  more   cost   effective,
            non-dilutive


                                       8


manner on a shareholder's  equity.  Alferon N Injection(R)  [Interferon  alfa-n3
(human leukocyte derived)] is a highly purified,  natural-source,  glycosylated,
multispecies  alpha  interferon  product.  There are  essentially  no antibodies
observed against natural interferon to date and the product has a relatively low
side-effect  profile.  Alferon is the only  natural-source,  multispecies  alpha
interferon  currently  sold in the U.S. and is also approved for sale in Mexico,
Germany, Singapore and Hong-Kong.

The   Alferon   targeted   market   consists   of   urologists,   proctologists,
dermatologists,  and Obstetricians/Gynecologists.  These physicians normally see
patients with papilloma  concondylomas  (genital warts) in their practice.  This
will be done in  existing  partnership  with our  strategic  partners  including
Gentiva Health Services,  Biovail Corporation and Esteve Laboratories,  all have
proven marketing expertise.

According  to the NIH,  there are one million new cases of venereal  warts every
year.

Pipeline products (alpha interferon)

The following  products,  together with other assets are to be acquired upon the
closing of the second ISI agreement, which is anticipated to occur in May 2003.

ALFERON N Injection(R) -Other applications

ALFERON N Injection(R)  [Interferon  alfa-n3 (human leukocyte derived)] has been
approved by the U.S. FDA for the treatment of certain types of genital warts and
has been  studied  for the  potential  treatment  of HIV,  Hepatitis C and other
indications.  ISI,  the Company  from which we obtained  our rights to ALFERON N
Injection(R)  had conducted  clinical trials with regard to the use of ALFERON N
Injection(R)  in the  treatment  of HIV and  Hepatitis  C.  While  ISI found the
results to be encouraging, in both instances, the FDA determined that additional
trials were necessary.

ALFERON N Gel(R)

ALFERON  N  GEL(R)  is  the  Company's  registered  trademark  for  its  topical
(dermatological) Natural Alpha Interferon preparation in a hydrophilic gel base.
This product is still in research and development.

ALFERON LDO(R)

ALFERON  LDO(R)  is the  registered  trademark  for the  low-dose,  oral  liquid
formulation  of Natural  Alpha  Interferon.  Two Phase 2 clinical  trials  using
ALFERON LDO for the treatment of HIV-infected patients have been completed.

There  can  be no  assurance  that  any  of  these  proposed  products  will  be
cost-effective,  safe,  and effective or that the Company will be able to obtain
FDA approval for such use. Furthermore, even if such approval is obtained, there
can be no assurance that such products will be  commercially  successful or will
produce significant revenues or profits for the Company.

                               EUROPEAN OPERATIONS

Our European operations were setup to prepare for the introduction of Hemispherx
products and to accelerate market penetration into the European market once full
approval is obtained from the European Medicine Evaluation Agency ("EMEA").  The
EMEA is the equivalent of the United States FDA. From a regulatory point of view
the member countries of the European  Economic Union ("EEU")  represent a common
market under the  jurisdiction of the EMEA.  However,  from a practical point of
view, every country is different regarding developing relations with the medical
community,  patient associations and obtaining  reimbursement for treatment from
the equivalent of Social Security Agencies and insurance carriers.  This program
will be integrated into our new commercial asset, ALFERON N Injection, as well.

Our   European   operations   have   assisted   the   growth   of  a  number  of
patient/physician educational associations.  The French Chronic Fatigue Syndrome
Association  has grown from 10 members in the year 2000 to 800 currently.  Every
major country now has an active educational association with substantial numbers
of members who regularly meet and "network". These programs have been modeled on
the  successful  experience in the U.S. of  conducting  twice a year meetings on
ME/CFS with Health and Human Services, FDA, NIH and Centers for Disease Control.

We maintain  contact with the EMEA,  keeping the agency aware of our activities,
as well as the health ministries in numerous countries in the European Union. In
early 2001,our  application  for "orphan" drug status for the use of Ampligen(R)
in ME/CFS was rejected because the Board found that the prevalence of ME/CFS was
significantly  above the 5 person per 10,000 limit required to grant orphan drug
status in the European  Union.  In addition,  we are  exploring  various ways to
accelerate the commercial availability of our products in the various nations of
the EEU,  including  potential  appreciation  of the  "foreign  import" rule for
accepting products already approved in the U.S.

Limited number ME/CFS patients were treated during 2002 with  Ampligen(R) in the
United  Kingdom,  Austria and Belgium under  existing  regulatory  procedures in
these countries,  which allow the therapeutic use of an experimental  drug under
certain  conditions.  These  procedures  allowed  us  to  recover  the  cost  of
Ampligen(R) used as well as to collect additional  clinical data.  Corresponding
procedures  are being  considered in several  other  countries at the request of
locally based physicians.

Our European operations are considering  implementing  clinical trials in Europe
for the use of  Ampligen(R) in the treatment of HIV/AIDS on the basis of the new
U.S.  Protocols  involving  the  use of the  drug  either  in  combination  with
"cocktail"  therapies or as part of a strategic  interruption  of the "cocktail"
therapies.  We plan to present these programs at European scientific conferences
in 2003.

The Efforts of our European  Operation has started to produce results.  In March
2002, our European Subsidiary  Hemispherx  Biopharma Europe, S.A.  ("Hemispherx,
S.A.") entered into a Sales and Distribution agreement with Laboratorios Del Dr.
Esteve  S.A.  ("Esteve").  Pursuant  to the terms of the  agreement,  Esteve was
granted the exclusive right to market Ampligen(R) in Spain, Portugal and Andorra
("Territory")  for the treatment of ME/CFS. In addition to other terms and other
projected  payments,  Esteve paid an initial and  non-refundable  fee of 625,000
Euros (approximately $563,000) to Hemispherx S.A. on April 24, 2002

Esteve  is  to  pay  a  fee  of  1,000,000   Euros  after  U.S.  Food  and  Drug
Administration  approval of Ampligen(R) for the treatment of ME/CFS and a fee of
1,000,000 Euros upon Spain's approval of the final marketing  authorization  for
using Ampligen(R)


                                       10


for the treatment of ME/CFS.  The agreement runs for the longer of 10 years from
the date of first arms-length sale in the Territory,  the expiration of the last
Hemispherx  patent  exploited  by  Esteve  or  the  period  of  regulatory  data
protection for Ampligen(R) in the applicable territory. Pursuant to the terms of
the agreement  Esteve is to conduct  clinical trials using  Ampligen(R) to treat
patients  with both HCV and HIV and is  required  to  purchase  certain  minimum
annual  amounts of  Ampligen(R).  The agreement is terminable by either party if
Ampligen(R)  is  withdrawn  form the  territory  for a  specified  period due to
serious  adverse  health or safety  reasons;  bankruptcy,  insolvency or related
issues of one of the parties;  or material  breach of the agreement.  Hemispherx
may  transform  the agreement  into a  non-exclusive  agreement or terminate the
agreement in the event that Esteve does not meet  specified  percentages  of its
annual minimum purchase  requirements under the agreement.  Esteve may terminate
the agreement in the event that  Hemispherx  fails to supply  Ampligen(R) to the
territory  for a  specified  period of time or  certain  clinical  trials  being
conducted by Hemispherx are not successful.

                                  MANUFACTURING

We outsource the manufacturing of Ampligen(R) to certain  contractor  facilities
in the United States and South Africa while maintaining full quality control and
supervision  of the process.  Nucleic Acid polymers  constitute the raw material
used in the  production  of  Ampligen(R).  We  acquire  our raw  materials  from
Ribotech, Ltd. ("Ribotech') located in South Africa.  Ribotech, is jointly owned
by us (24.9%) and Bioclones,  proprietary,  Ltd. (75.1%).  Bioclones manages and
operates  Ribotech.  Two  manufacturers  in the United  States are  available to
provide the  polymers if  Ribotech is unable to supply our needs.  Sourcing  our
needs  from  other  suppliers  could  result  in a cost  increase  for  our  raw
materials.

Until 1999, we distributed  Ampligen(R) in the form of a freeze-dried  powder to
be  formulated  by  pharmacists  at the site of use. We  perfected a  production
process to produce ready to use liquid  Ampligen(R) in a dosage form, which will
mainly be used upon commercial approval of Ampligen(R).  At the present time, we
have  engaged  the  services  of   Schering-Plough   Products  to  mass  produce
ready-to-use  Ampligen(R)  doses.  There  are  other  pharmaceutical  processing
companies that can supply our production needs.

Bioclones (PTY) Ltd. has also successfully completed a series of production runs
for liquid  Ampligen(R)  doses.  This was done at  Ribotech's  facility in South
Africa that has inspection  approval by both the US FDA and the Medicine Control
Authority of the United Kingdom.  Bioclones (PTY) Ltd. Is headquartered in South
Africa and is the  majority  owner in  Ribotech,  Ltd.  (the Company owns 24.9%)
which  produces  most of the polymers  used in  manufacturing  Ampligen(R).  The
licensing  agreement  with  Bioclones  presently  includes  South Africa,  South
America, Ireland, New Zealand and the United Kingdom.

We  currently  occupy  and use the New  Brunswick,  New  Jersey  laboratory  and
production  facility  owned by ISI. We are in the process of acquiring  title to
these  facilities  pursuant to our second asset  acquisition  agreement with ISI
(see RECENT  FINANCING  AND ASSET  ACQUISITIONS  below for more  details).  This
facility is approved by the FDA for the manufacture of Alferon N.


                                       11


All production facilities employ Good Manufacturing Practices.(EGMP)

Good  Manufacturing  Practices  (GMP)  require  that a product  be  consistently
manufactured  to an identical  potency  (strength) and purity with each lot, and
that  the  manufacturing  facility  itself  and all the  equipment  therein,  be
certified to operate within a strict set performance standards.

                             MARKETING/DISTRIBUTIONS

Our  marketing  strategy  for  Ampligen(R)  reflects the  differing  health care
systems around the world, and the different  marketing and  distribution  system
that are used to supply pharmaceutical  products to those systems. In the United
States, we expect that, subject to receipt of regulatory  approval,  Ampligen(R)
will  be  utilized  in  three  medical  arenas:  physicians'  offices,  clinics,
hospitals and the home  treatment  setting.  We currently  plan to use a service
provide  in the home  infusion  (non-hospital)  segment  of the U.S.  market  to
execute direct marketing  activities,  conduct physical  distribution of product
and handle billing and  collections.  Accordingly,  we are developing  marketing
plans to facilitate the product distribution and medical support for indication,
if and when they are approved, in each arena. We believe that this approach will
facilitate the generation of revenue  without  incurring the  substantial  costs
associated  with a sales  forces.  Furthermore,  management  believes  that  the
approach will enable us to retain many options for future marketing  strategies.
In February  1998,  the Company and Gentiva Health  Services  (formerly  Olstein
Heatlh  services)  entered  into  a  distribution/specialty  agreement  for  the
distribution  of Ampligen(R) for the treatment of ME/CFS patients under the U.S.
treatment protocols.

In Europe,  we plan to adopt a  country-by-country  and,  in certain  cases,  an
indication-by-indication  marketing strategy due to the heterogeneity regulation
and  alternative  distribution  systems in these area. We also plan to adopt and
indication-by-indication  strategy  in Japan.  Subject to receipt of  regulatory
approval,  we plan to seek strategic partnering  arrangement with pharmaceutical
companies to facilitate introductions in these areas. The relative prevalence of
people  from  target  indications  for  Ampligen(R)   varies   significantly  by
geographic  region,  and we intend to adjust our clinical and marketing planning
to reflect the special of each area. In countries in South  America,  the United
Kingdom,  Ireland, Africa,  Australia,  Tasmania, New Zealand, and certain other
countries and  territories,  we  contemplate  marketing our product  through our
relationship with Bioclones pursuant to the Bioclones Agreement.

Our marketing and  distribution  plan for Alferon N is focused on increasing the
sales of Alferon N Injection for the  intralesional  treatment of refractory and
recurring  external  genital  warts in  adults.  We will reach out to a targeted
audience of physicians  consisting of Ob/GYNSs,  Urologists,  Proctologists  and
Dermatologists  and  simultaneously  create  product  awareness  in the  patient
population  through several media and health  organizations.  Different regional
meetings and seminars are scheduled during which guest speakers will explain the
therapeutic benefits and safety profile of Alferon.  Additional exposure will be
created by exhibiting at several STD related conferences, expanded web presence,
mailings and publications.  We also plan to engage a contact sales  organization
in order to build up a nationwide  network of dedicated  representatives  in the
U.S. and Europe.  This will be done while  working with our  strategic  partners
including Gentiva Health Services, Biovail Corporation an Esteve Laboratories.

AGREEMENTS"

                                   COMPETITION

Our potential competitors are among the largest pharmaceutical  companies in the
world,  are  well  known  to the  public  and the  medical  community,  and have
substantially   greater   financial   resources,    product   development,   and
manufacturing and marketing capabilities than we have.

These  companies  and their  competing  products may be more  effective and less
costly than our products.  In addition,  conventional drug therapy,  surgery and
other  more  familiar   treatments  will  offer  competition  to  our  products.
Furthermore, our competitors have significantly greater experience than we do in
pre-clinical testing and human clinical trials of pharmaceutical products and in
obtaining  FDA,  EMEA Health  Protection  Branch  ("HPB")  and other  regulatory
approvals of products. Accordingly, our competitors may succeed in obtaining FDA
EMEA and HPB product  approvals  more  rapidly  than us. If any of our  products
receive regulatory  approvals and we commence  commercial sales of our products,
we will also be competing with respect to manufacturing efficiency and marketing
capabilities,  areas in which we have no experience. Our competitors may possess
or obtain patent protection or other intellectual  property rights that prevent,
limit or  otherwise  adversely  affect our  ability  to  develop or exploit  our
products.

The  major  competitors  with  drugs  to  treat  HIV  diseases  include  "Gilead
Pharmaceutical,  Pfizer,  Bristol-Myers,  Abbott Labs and Schering-Plough  Corp.
("Schering").  ALFERON N Injection currently competes with a product produced by
Schering for treating  genital warts.  3m  Pharmaceutical  also has received FDA
approval for its immune response  modifier  product for the treatment of genital
and perianal warts.

                              GOVERNMENT REGULATION

Regulation by governmental  authorities in the U.S. and foreign countries is and
will be a  significant  factor in the  manufacture  and  marketing  of ALFERON N
products  and  our  ongoing   research  and  product   development   activities.
Ampligen(R)  and the products  developed  from the ongoing  research and product
development   activities   will   require   regulatory   clearances   prior   to
commercialization.  In particular, human new drug products for human are subject
to rigorous  preclinical  and clinical  testing as a condition for clearances by
the FDA and by similar authorities in foreign countries.  The lengthy process of
seeking these  approvals,  and the ongoing process of compliance with applicable
statutes  and  regulations,  has  required  and will  continue  to  require  the
expenditure of substantial resources.  Any failure by us or our collaborators or
licensees  to obtain,  or any delay in  obtaining,  regulatory  approvals  could
materially  adversely  affect the  marketing  of any  products  developed by the
Company and its ability to receive product or royalty revenue.  We have received
orphan drug designation for certain therapeutic indications,  which might, under
certain conditions, accelerate the process of drug commercialization.  ALFERON N
is only approved for use in treating  genital warts.  Use of Alferon N for other
applications requires regulatory approval.


                                       13


A  "Fast-Track"  designation  by the  FDA,  while  not  affecting  any  clinical
development  time per se, has the  potential  effect of reducing the  regulatory
review time by 50 percent (50%) from the time that a commercial drug application
is actually submitted for final regulatory review. Regulatory agencies may apply
a "Fast Track"  designation  to a potential new drug to accelerate  the approval
and  commercialization   process.  Criteria  for  "Fast  Track"  include:  a)  a
devastating  disease  without  adequate  therapy and b)  laboratory  or clinical
evidence that the candidate drug may address the unmet medical need. As of March
31, 2003, we have not received a Fast-Track designation for any of our potential
therapeutic  indications although we have received "Orphan Drug Designation" for
both ME/CFS and HIV/AIDS in the United States.  We will continue to present data
from time to time in support of obtaining  accelerated  review.  We have not yet
submitted any New Drug Application  (NDA) for Ampligen(R) or any other drug to a
North  American  regulatory  authority.   There  are  no  assurances  that  such
designation  will be granted,  or if granted,  there are no assurances that Fast
Track  designation  will  materially  increase  the  prospect  of  a  successful
commercial application. In 2000 we submitted an emergency treatment protocol for
clinically-resistant  HIV  patients,  which  was  withdrawn  by  us  during  the
statutory  30 day  regulatory  review  period  in favor  of a set of  individual
physician-generated applications. There are no assurances that authorizations to
commence such treatments will be granted by any regulatory authority or that the
resultant treatments, if any, will support drug efficacy and safety. In 2001, we
did receive FDA authorization for two separate Phase IIb HIV treatment protocols
in which  the  Company's  drug is  combined  with  certain  presently  available
antiretroviral  agents.  Interim  results  were  presented  in 2002  at  various
international scientific meetings.

We are  subject  to  various  federal,  state and local  laws,  regulations  and
recommendations relating to such matters as safe working conditions,  laboratory
and manufacturing  practices, the experimental use of animals and the use of and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious  disease  agents,  used in connection with our research
work.  We  believe  that  our  Rockville,  Maryland  manufacturing  and  quality
assurance/control  facility  is in  substantial  compliance  with  all  material
regulations  applicable  to these  activities  as  advanced  by  European  Union
Inspections  team which  conducted  detailed  audits in year 2000.  However,  we
cannot give assurances that facilities owned and operated by third parties, that
are utilized in the manufacture of our products, are in substantial  compliance,
or if presently  in  substantial  compliance,  will remain so. These third party
facilities include manufacturing  operations in San Juan, Puerto Rico; Capetown,
South Africa; Columbia, Maryland; Melbourne,  Australia; and potential expansion
within the United States to new and larger facilities in 2003.

                RESEARCH AND DEVELOPMENT/COLLABORATIVE AGREEMENTS

In 1994, we entered into a licensing agreement with Bioclones (Property) limited
("Bioclones") for manufacturing and international  market development in Africa,
Australia,  New  Zealand,  Tasmania,  the United  Kingdom,  Ireland  and certain
countries in South Africa, of Ampligen(R) and Oragen(TM). Bioclones is to pursue
regulatory  approval  in the areas of its  franchise  and is required to conduct
Hepatitis  clinical trials,  based on international GMP and GLP standards.  Thus
far,  these  Hepatitis  studies have not yet  commenced  to a meaningful  level.
Bioclones  has been given the first  right of refusal,  subject to  pricing,  to
manufacture  that amount of polamers  utilized in the  production of Ampligen(R)
sufficient to satisfy at least one-third of the worldwide  sales  requirement of
Ampligen(R) and other nucleic acid-derived drugs.  Pursuant to this arrangement,
we received 1) access to  worldwide  markets 2)  commercial-scale  manufacturing


                                       14


resources,  3) a $3  million  cash  payment in 1995 from  Bioclones,  4) a 24.9%
ownership  in  Ribotech,  Ltd. a company  set up by  Bioclones  to  develop  and
manufacture  RNA drug  compounds,  and 5) royalties  of 8% on Bioclones  nucleic
acid-derived  drug  sales  in  the  licensed  territories.  The  agreement  with
Bioclones terminates three years after the expiration of the last of the patents
supporting the license granted to Bioclones,  subject to earlier  termination by
the  parties  for  uncured  defaults  under  the  agreement,  or  bankruptcy  or
insolvency of either party. The last patent expires on December 22, 2012.

In August,  1998,  we entered  into a strategic  alliance  with  Gentiva  Health
Services  (formerly  known as Olsten  Health Care  Services) to develop  certain
marketing  and  distribution  capacity  for  Ampligen(R)  in the United  States.
Gentiva is one of the nation's  largest home health care companies with over 400
offices and sixty  thousand  caregivers  nationwide.  Pursuant to the agreement,
Gentiva assumed  certain  responsibilities  for  distribution of Ampligen(R) for
which they receive a fee. Through this arrangement,  Hemispherx may mitigate the
necessity of incurring  certain  up-front  costs.  Gentiva also works with us in
connection  with the Amp 511 ME/CFS cost  recovery  treatment  program,  Amp 516
ME/CFS PHASE III clinical  trial and the Amp  719(combining  Ampligen with other
antiviral drugs in HIV-salvage therapy and Amp 720 HIV Phase IIb clinical trials
now under way.  There can be no  assurances  that this  alliance  will develop a
significant  commercial position in any of its targeted chronic disease markets.
The agreement had an initial one year term from February 9, 1998 with successive
additional  one (1) year terms unless  either party  notifies the other not less
than one hundred eighty (180) days prior to the  anniversary  date of its intent
to terminate the  agreement.  Also,  the  agreement  may be  terminated  for the
uncured  defaults,  or  bankruptcy  or  insolvency  of  either  party  and  will
automatically  terminate  upon our receiving  New Drug Approval for  Ampligen(R)
from the FDA, at which time, a new  agreement  will need to be  negotiated  with
Gentiva  or  another  major drug  distributor.  There  were no initial  fees and
subsequent fees paid under this agreement total $59,000 for services performed.

We have acquired a series of patents on  Oragen(TM),  potentially  an oral broad
spectrum antiviral,  Immunological  enhancers through a licensing agreement with
Temple  University.  We were granted an exclusive  worldwide license from Temple
for the Oragen(TM)  products.  Pursuant to the arrangement,  we are obligated to
pay  royalties  of 2% to 4% on  sales  of  Oragen(TM),  depending  on  how  much
technological  assistance is required of Temple.  There were no initial fees and
we  currently  pay  minimum  royalties  of  $30,000  per year to  Temple.  These
compounds  have been evaluated in various  academic and government  laboratories
for application to Chronic viral and immunological disorders.  This agreement is
to remain in effect until the date that the last licensed  patent expires unless
terminated  sooner by mutual consent or default due to royalties not being paid.
The last Oragen(TM) patent expires on August 22, 2015.

In  December,  1999,  we entered  into an  agreement  with  Biovail  Corporation
International   ("Biovail").   Biovail   is  an   international   full   service
pharmaceutical   company   engaged  in  the   formulation,   clinical   testing,
registration and manufacture of drug products  utilizing  advanced drug delivery
systems.  Biovail is  headquartered  in Toronto,  Canada.  The agreement  grants
Biovail the exclusive distributorship of our product in the Canadian territories
subject to certain terms and  conditions.  In return,  Biovail agrees to conduct
certain   pre-marketing   clinical  studies  and  market  development  programs,
including without limitation, expansion of the Emergency Drug Release Program in
Canada with respect to our products. In addition, Biovail agrees to work with us
in  preparing


                                       15


and filing a New Drug Submission with Canadian Regulatory  Authorities.  Biovail
invested $2,250,000 in Hemispherx equity at prices above the then current market
price  and  agreed  to make an  additional  investment  of  $1,750,000  based on
receiving  approval  to  market  Ampligen(R)  in  Canada  from  the  appropriate
regulatory  authorities  in  Canada.  The  Agreement  requires  Biovail  to  buy
exclusively  from us and penetrate  certain market segments at specific rates in
order to maintain market exclusivity.  The agreement  terminates on December 15,
2009,  subject to successive two (2) year  extensions by the parties and subject
to earlier  termination by the parties for uncured defaults under the agreement,
bankruptcy  or  insolvency  of either  party,  or withdrawal of our product from
Canada for a period of more than ninety (90) days for serious  adverse health or
safety reasons.

In 1998, the Company  invested  $1,074,000 for a 3.3% equity  interest in R.E.D.
Laboratory ("R.E.D.").  R.E.D. is a privately held biotechnology company for the
development of diagnostic markers for Chronic Fatigue Syndrome and other chronic
immune  diseases.  Primarily,  R.E.D.'s  research  and  development  is based on
certain  technology owned by Temple University and licensed to R.E.D. We have an
informal collaboration arrangement with R.E.D. to assist in this development. We
have  supplied  scientific  data with  respect to ME/CFS and engaged  R.E.D.  to
conduct  certain blood tests for our ME/CFS  clinical  trials.  We have no other
obligations to R.E.D.  R.E.D. is  headquartered  in Belgium.  The investment was
recorded at cost in 1998.  During three months ended June 2002 and December 2002
respectively,   we  recorded  a  non-cash   charge  of  $678,000   and  $396,000
respectively,  to  operations  with respect to our  investment  in R.E.D.  These
charges  were  the  result  of our  determination  that  R.E.D.'s  business  and
financial  position had  deteriorated  to the point that our investment had been
permanently impaired.

In May 2000, we acquired an interest in Chronix  Biomedical  Corp.  ("CHRONIX").
Chronix  focuses upon the development of diagnostics  for chronic  diseases.  We
issued  100,000  shares  of  common  stock  to  Chronix  toward  a total  equity
investment of $700,000.  Pursuant to a strategic alliance agreement, we provided
Chronix with $250,000 to conduct  research in an effort to develop  intellectual
property on potential new products for diagnosing and treating  various  chronic
illnesses such as ME/CFS.  The strategic  alliance agreement provides us certain
royalty rights with respect to certain diagnostic technology developed from this
research and a right of first refusal to license certain therapeutic  technology
developed from this research.  The strategic alliance agreement provides us with
a  royalty  payment  of ten per  cent  (10%)  of all  net  sales  of  diagnostic
technology  developed by Chronix for diagnosing  Chronic Fatigue Syndrome,  Gulf
War Syndrome and Human Herpes Virus-6 associated diseases. The royalty continues
for the  longer of  twelve  years  from  September  15,  2000 or the life of any
patent(s)  issued  with  regard  to the  diagnostic  technology.  The  strategic
alliance  agreement  also provides us with the right of first refusal to acquire
an exclusive worldwide license for any and all therapeutic  technology developed
by  Chronix  on or  before  September  14,  2012 for  treating  Chronic  Fatigue
Syndrome,  Gulf War  Syndrome and Human Herpes  Virus-6  associated.  During the
quarter ended  December 31, 2002, we recorded a noncash  charge of $292,000 with
respect to our investment in Chronix. This impairment reduces our carrying value
to reflect a permanent  decline in Chronix's market value based on their current
proposed equity offerings.

In April, 1999 we acquired a 30% equity position in the California  Institute of
Molecular  Medicine  ("CIMM")  for  $750,000.  CIMM'S  research  is  focused  on
developing  therapies  for use in  treating  patients  affected  by  Hepatitis C
("HCV"). We use the equity method of accounting with respect to this investment.
During the fourth quarter of 2001 we recorded a non-cash charge of $485,000 with


                                       16


respect to our investment in CIMM. This was a result of our  determination  that
CIMM's  operations  have not yet  evolved to the point  where the full  carrying
value of our investment  could be supported  based on that  company's  financial
position  and  operating   results.   During  2002,  CIMM  continued  to  suffer
significant losses resulting in a deterioration of its financial condition.  The
$485,000 written off during 2001 represented the unamortized balance of goodwill
included  as part of the  Company's  investment.  Additionally,  during 2001 the
Company  reduced  its  investment  in CIMM based on its  percentage  interest in
CIMM's  continued  operating  losses.  The  Company's  remaining  investment  at
December 31, 2001 in CIMM,  representing  its 30%  interest in CIMM's  equity at
such date, was not deemed to be permanently  impaired but was completely written
off during 2002.  Such amount was not  material.  These charges are reflected in
the  Consolidated  Statements  of Operations  under the caption  "Equity loss in
unconsolidated  affiliate".  We still believe CIMM will succeed in their efforts
to advance  therapeutic  treatment  of HCV. We believe  that CIMM's  Hepatitis C
diagnostic  technology  has great promise and will fill a  long-standing  global
void in the collective  abilities to diagnose and treat Hepatitis C infection at
an early stage of the disorder.

In March 2002, our European subsidiary  Hemispherx S.A. entered into a Sales and
Distribution  agreement  with  Esteve.  Pursuant to the terms of the  agreement,
Esteve was granted the exclusive right to market Ampligen(R) in Spain,  Portugal
and Andorra for the  treatment  of ME/CFS.  In addition to other terms and other
projected  payments,  Esteve  agreed to conduct  certain  clinical  trials using
Ampligen(R)  in the  patient  population  coinfected  with  hepatitis  C and HIV
viruses.  The  agreement  runs for the longer of 10 years from the date of first
arms-length sale in the Territory,  the expiration of the last Hemispherx patent
exploited by Esteve or the period of regulatory  data protection for Ampligen(R)
in the applicable territory. Pursuant to the terms of the agreement Esteve is to
conduct  clinical  trials using  Ampligen(R) to treat patients with both HCV and
HIV and is required to purchase  certain  minimum annual amounts of Ampligen(R).
The agreement is terminable by either party if Ampligen(R) is withdrawn form the
territory  for a  specified  period  due to  serious  adverse  health  or safety
reasons;  bankruptcy,  insolvency  or related  issues of one of the parties;  or
material breach of the agreement.  Hemispherx may transform the agreement into a
non-exclusive agreement or terminate the agreement in the event that Esteve does
not meet specified percentages of its annual minimum purchase requirements under
the agreement.  Esteve may terminate the agreement in the event that  Hemispherx
fails to supply  Ampligen(R) to the territory for a specified  period of time or
certain  clinical trials being  conducted by Hemispherx are not successful.  The
last patent with respect to this agreement expires on June 5, 2012.

The  development of our Nucleic Acid Based  products  requires the commitment of
substantial  resources  to  conduct  the  time-consuming  research,  preclinical
development,  and clinical  trials that are  necessary  to bring  pharmaceutical
products to market and to establish  commercial-scale  production  and marketing
capabilities.  During  our last  three  fiscal  years,  we have  directly  spent
approximately  $16,862,000 in research and development,  of which  approximately
$4,946,000 was expended in the year ended December 31, 2002.  These direct costs
do not include the overhead and  administrative  costs  necessary to support the
research  and  development  effort.  Our  European  subsidiary  has an exclusive
license on all the technology and support from us concerning Ampligen(R) for the
use of ME/CFS and other  applications  for all  countries of the European  Union
(excluding  the  UK  where  Bioclones  has  a  marketing  license)  and  Norway,
Switzerland,  Hungary,


                                       17


Poland, the Balkans,  Russia,  Ukraine,  Romania,  Bulgaria,  Slovakia,  Turkey,
Iceland and  Liechtenstein.  As mentioned above,  Hemispherx S.A. entered into a
Sales and  distribution  Agreement  with  Esteve.  Pursuant to the terms of this
agreement,  Esteve has been granted the exclusive  right in Spain,  Portugal and
Andorra  to market  Ampligen(R)  for the  treatment  of  ME/CFS.  See  "EUROPEAN
OPERATIONS" above for more detailed information.

                                 HUMAN RESOURCES

As of  March  31,  2003  we had 40  personnel  working  on  the  development  of
Ampligen(R)   consisting  of  19  full  time,  3  part-time   employees  and  18
regulatory/research  medical  personnel on a part-time basis.  Part time parties
are paid on a per  diem or  monthly  basis.  30  personnel  are  engaged  in our
research,  development,  clinical,  manufacturing  effort.  Ten of our personnel
perform  regulatory,   general   administration,   data  processing,   including
bio-statistics, financial and investor relations functions.

In addition  to the  foregoing  personnel,  on March 11,  2003,  pursuant to our
agreement with ISI, we added personnel from ISI to our payroll  consisting of 12
part-time and 17 full-time employees.

We believe that the  combination of Hemispherx and ISI Scientific  employees has
1) significantly  strengthened our overall  organization,  2) added expertise to
monitor and  complete  our  ongoing  clinical  trials and 3)  improved  our data
management and system administration.

While we have been successful in attracting  skilled and experienced  scientific
personnel, there can be no assurance that the Company will be able to attract or
retain the necessary qualified employees and/or consultants in the future.

                     RECENT FINANCING AND ASSET ACQUISITIONS

On March 12, 2003, we issued an aggregate of  $5,426,000 in principal  amount of
6% Senior  Convertible  Debentures  due  January 31,  2005 and an  aggregate  of
743,288  Warrants  to  two  investors  in  a  private  placement  for  aggregate
anticipated  gross  proceeds of $4,650,000  realizing net proceeds of $4,423,000
after  legal  and  related  costs.  Pursuant  to the  terms  of the  Debentures,
$1,550,000 of the proceeds from the sale of the  Debentures  have been held back
and will be released to us if, and only if, we acquire ISI's facility  within 90
days from March 12, 2003.  Consummation  of the  acquisition  of ISI's  facility
requires,  among  other  things,  approval  by ISI's  shareholders  and  certain
environmental  approvals.  As of the date hereof,  there is the possibility that
either or both approvals may not be obtained  within the required 90 day period.
Our  failure to complete  the  acquisition  within the 90 day period  would be a
technical  default of the terms of the Debentures  and,  absent consent from the
Debenture  holders for additional time, would result in our having to redeem the
securities.  If we do not receive the additional Debenture funds as planned and,
especially if we are required to redeem the Debentures,  our financial condition
would be materially and adversely  affected and we would probably have to reduce
or possibly  curtail  operational  spending  including  some  critical  clinical
effort.  The  Debentures  mature on January 31, 2005 and bear interest at 6% per
annum,  payable  quarterly  in cash  or,  subject  to  satisfaction  of  certain
conditions,  common stock. Any shares of common stock issued to the investors as
payment of interest  shall be valued at 95% of the average  closing price of the
common  stock


                                       18


during the five  consecutive  business  days  ending on the third  business  day
immediately  preceding the  applicable  interest  payment date.  Pursuant to the
terms and conditions of the Senior Convertible  Debentures,  we have pledged all
of our assets other than intellectual property, as collateral and are subject to
comply with certain financial and negative covenants,  which include but are not
limited to the repayment of principal  balances upon achieving  certain  revenue
milestone.

The  Debentures  are  convertible  at the  option of the  investors  at any time
through January 31, 2005 into shares of our common stock.  The conversion  price
under the  Debentures  is fixed at $1.46 per share,  subject to  adjustment  for
anti-dilution  protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in effect.

The investors  also  received  Warrants to acquire at any time through March 12,
2008 an  aggregate  of  743,288  shares of common  stock at a price of $1.68 per
share.  On March 12, 2004,  the exercise price of the Warrants will reset to the
lesser of the  exercise  price then in effect or a price equal to the average of
the daily price of the common  stock  between  March 13, 2003 and March 11, 2004
(but in no event less than $1.176 per share).  The exercise price (and the reset
price)  under  the  Warrants  also  is  subject  to  similar   adjustments   for
anti-dilution protection.

We entered into a registration rights agreement with the investors in connection
with the issuance of the Debentures and the Warrants.  The  registration  rights
agreement  requires  that we register the shares of common stock  issuable  upon
conversion of the  Debentures,  as interest  shares under the Debenture and upon
exercise  of the  Warrants.  In  accordance  with  this  agreement,  we  filed a
registration  statement on form S-3 with the Securities and Exchange Commission.
If the registration  statement is not declared  effective within the time period
required by the  agreement  or,  after it is declared  effective  and subject to
certain exceptions, sales of all shares required to be registered thereon cannot
be made pursuant thereto, then we will be required to pay to the investors their
pro rata  share of $3,635  for each day any of the above  conditions  exist with
respect to this registration statement.

On March 11,  2003,  we executed  two  agreements  with ISI to purchase  certain
assets of ISI.

In the first agreement with ISI, the Company acquired ISI's inventory of ALFERON
N  Injection(R),  and a limited license for the  production,  manufacture,  use,
marketing and sale of this product. For these assets, the Company:

      (i) issued 487,028 shares of its common stock; and

      (ii) agreed to pay ISI 6 % of the net sales of the Product.

The  Company  also is required to pay ISI a service fee and pay certain of ISI's
obligations related to the product and their employees.  These costs approximate
$1,170,996.

In the second  agreement  with ISI, ISI has agreed to sell to the Company all of
ISI's rights to the product and other assets  related to the product  including,
but not limited to, real estate and  machinery.  For these  assets,  the Company
will:

      (i) issue an additional 487,028 shares of its common stock; and


                                       19


      (ii) continue to pay ISI 6 % of the net sales of the product.

In addition,  the Company will be required to satisfy three  obligations of ISI.
The Company  will  satisfy  two of these  obligations,  pursuant to  forbearance
agreements with The American  National Red Cross and GP Strategies  Corporation,
two of ISI's  creditors,  by issuing an  aggregate  of 581,761  shares of common
stock to these creditors.  The third obligation is approximately $521,000 and is
secured by a lien on the property.

Pursuant to the  agreements  with ISI and its  creditors,  the Company is in the
process of registering  the foregoing  shares issued and to be issued to ISI and
its  creditors  for  public  sale in the  registration  statement  on  form  S-3
mentioned  above.  Except for  125,000 of the shares  issued and to be issued to
ISI, the Company has guaranteed  the market value of the shares  retained by ISI
and the two  creditors  through March 11, 2005 to be $1.59 per share for a total
of $2,275,000.  ISI and the creditors are permitted to periodically sell certain
amounts of their shares.

Our  overall  consideration  for the  assets  acquired  in the first and  second
agreement consisting of stock,  assumption of debt,  commitments and obligations
relating to the real estate and  equipment is expected to be $4,149,996 of which
$1,691,996 will be cash.

We will account for these transactions as a Business Combination under Statement
of  Financial  Accounting  Standards  ("SFAS") No. 141  Accounting  for Business
Combinations.

During March 2002, Hemispherx Biopharma Europe, S.A., our Luxembourg subsidiary,
was authorized to issue up to 22,000,000 Euros of seven percent (7%) convertible
preferred securities. Such securities will be guaranteed by the Company and will
be  converted  into a  specified  number of shares  pursuant  to the  securities
agreement.  Conversion is to occur on the earlier of an initial public  offering
of Hemispherx S.A. on a European stock exchange or September 30, 2003.

On March 13, 2003, we issued  347,445 shares of our common stock to Provesan SA,
an affiliate of Esteve, in exchange for 1,000,000 Euros of convertible preferred
equity certificates of Hemispherx  Biopharma Europe,  S.A., owned by Esteve, and
all dividends  earned and to be earned through  September 30, 2003. We agreed to
register  the  shares  issued  to  Provesan  SA,  and we are in the  process  of
registering  these shares for public sale in the registration  statement of form
S-3 mentioned above.

On March 31, 2003 we settled our  outstanding  claim with an  insurance  company
relating to  reimbursement of expenses in connection with our Asensio law suits.
See Legal Proceedings for more detailed information. The terms of the settlement
are confidential.  We have applied the net proceeds of approximately  $1,050,000
as a  reduction  in general and  administrative  expenses  in our  statement  of
operations for the year ended December 31, 2002.

As of December 31, 2002, we had approximately  $2,811,000 in cash and short term
investments.  We believe  that these funds plus 1) the  anticipated  infusion of
approximately  $4.4 million in net proceeds  from the  Debenture  placement,  2)
projected  net cash  flow  from the  acquisition  of  ALFERON N and 3) the funds
received  from  the  insurance  settlement  should  be  sufficient  to meet  our
operating requirements for the next 12 months.

In addition,  we may raise  additional funds through  additional  equity or debt


                                       20


financing,  collaborative  arrangements with corporate partners, lease financing
or from other sources in order to complete the necessary clinical trials and the
regulatory  approval  processes  and  begin  commercializing  our  products.  If
adequate  funds  are not  available  from  operations  and if we are not able to
secure  additional  sources  of  financing  on  acceptable  terms,  we  would be
materially adversely affected in our commercialization process.

                                  RISK FACTORS

The following cautionary  statements identify important factors that could cause
our  actual   result  to  differ   materially   from  those   projected  in  the
forward-looking  statements made in this Form 10-K/A. Among the key factors that
have a direct bearing on our results of operations are:

No assurance of successful product development

      Ampligen(R) and related  products.  The development of Ampligen(R) and our
other related products is subject to a number of significant risks.  Ampligen(R)
may be found to be ineffective or to have adverse side effects,  fail to receive
necessary  regulatory  clearances,  be difficult to  manufacture on a commercial
scale,  be  uneconomical  to market or be precluded  from  commercialization  by
proprietary  right of third  parties.  Our  products  are in  various  stages of
clinical and pre-clinical  development and, require further clinical studies and
appropriate  regulatory  approval  processes  before  any such  products  can be
marketed.  We do not know when, or if ever,  Ampligen(R)  or our other  products
will be generally  available for commercial sale for any indication.  Generally,
only a  small  percentage  of  potential  therapeutic  products  are  eventually
approved by the U.S. Food and Drug Administration ("FDA") for commercial sale.

      ALFERON N  Injection(R).  Although  ALFERON N Injection  is  approved  for
marketing for the treatment of genital  warts,  to date it has not been approved
for other  applications.  We face many of the risks discussed above, with regard
to  developing  this  product for use to treat other  ailments  such as multiple
sclerosis and cancer.

Our drug and related  technologies are investigational and subject to regulatory
approval. If we are unable to obtain regulatory approval, our operations will be
significantly affected.

      All  of our  drugs  and  associated  technologies  other  than  ALFERON  N
Injection  are  investigational  and must receive prior  regulatory  approval by
appropriate  regulatory  authorities  for general use and are currently  legally
available only through  clinical  trials with specified  disorders.  At present,
ALFERON N Injection is only approved for the treatment of genital warts.  Use of
ALFERON N Injection for other applications will require regulatory approval.  In
this regard,  Interferon Sciences,  Inc., the Company from which we obtained our
rights to  ALFERON N  Injection,  conducted  clinical  trials  related to use of
ALFERON N Injection for treatment of HIV and Hepatitis C. In both instances, the
FDA determined that additional studies were necessary in order to fully evaluate
the efficacy of ALFERON N  Injection(R)  in the treatment of HIV and Hepatitis C
diseases.  We have no obligation or plans to conduct these additional studies at
this  time.  Our  principal   development   efforts  are  currently  focused  on
Ampligen(R),  which has not been  approved for  commercial  use.  Our  products,
including   Ampligen(R),   are  subject  to  extensive  regulation  by  numerous
governmental  authorities in the U.S. and other  countries,  including,  but not
limited to, the FDA in the U.S., the Health Protection  Branch("HPB") of Canada,
and the  European


                                       21


Medical Evaluation Agency ("EMEA") in Europe.  Obtaining regulatory approvals is
a rigorous  and lengthy  process and  requires the  expenditure  of  substantial
resources.  In order to obtain final regulatory  approval of a new drug, we must
demonstrate to the  satisfaction  of the  regulatory  agency that the product is
safe  and   effective  for  its  intended  uses  and  that  we  are  capable  of
manufacturing  the product to the applicable  regulatory  standards.  We require
regulatory approval in order to market Ampligen(R) or any other proposed product
and receive product revenues or royalties. We cannot assure you that Ampligen(R)
will ultimately be demonstrated  to be safe or efficacious.  In addition,  while
Ampligen(R)  is authorized  for use in clinical  trials in the United States and
other countries,  we cannot assure you that additional  clinical trial approvals
will be  authorized  in the  United  States or in other  countries,  in a timely
fashion  or at  all,  or  that  we  will  complete  these  clinical  trials.  If
Ampligen(R) or one of our other products does not receive regulatory approval in
the U.S. or elsewhere, our operations will be materially adversely effected.

We may  continue to incur  substantial  losses and our future  profitability  is
uncertain.

      We began operations in 1966 and last reported net profit from 1985 through
1987. Since 1987, we have incurred  substantial  operating losses, as we pursued
our clinical trial effort and expanded our efforts in Europe. As of December 31,
2002 our  accumulated  deficit was  approximately  $99,000,000.  We have not yet
generated  significant  revenues from our products and may incur substantial and
increased  losses in the  future.  We cannot  assure  that we will ever  achieve
significant  revenues from product sales or become profitable.  We require,  and
will continue to require, the commitment of substantial resources to develop our
products.  We  cannot  assure  that  our  product  development  efforts  will be
successfully completed or that required regulatory approvals will be obtained or
that  any  products  will  be  manufactured   and  marketed   successfully,   or
profitability.

We may require additional financing which may not be available.

      The development of our products will require the commitment of substantial
resources to conduct the time-consuming research,  preclinical development,  and
clinical trials that are necessary to bring  pharmaceutical  products to market.
Based  upon  our  current  operating  plan,  we  anticipate  that we  will  need
approximately  $5,400,000  over the next 12 months,  inclusive  of revenues  and
financing,  to sustain our operations.  In March 2003, we received $2,873,000 in
initial net proceeds from the sale of the Debentures and Warrants and,  pursuant
to the terms of the  Debentures,  if and when we close on the second  Interferon
Sciences  asset  acquisition,   we  will  receive  additional  net  proceeds  of
$1,550,000.  We  anticipate  receipt of revenues and proceeds  from the sales of
Ampligen(R) under the Cost Recovery Clinical Programs and, possibly,  funds from
the exercise of outstanding  non-public warrants. We also anticipate significant
revenues from our recently acquired commercial product,  Alferon N. As of May 1,
2003, we had approximately  $3.6 Million in cash and short term investments.  We
believe that these funds plus 1) the anticipated infusion of approximately $1.55
million in  remaining  net  proceeds  from the  Debenture  placement  and 2) the
projected  net cash flow from the sale of ALFERON N should be sufficient to meet
our  operating  requirement  for  the  next 12  months.  We may  need  to  raise
additional  funds  through  additional  equity or debt  financing  or from other
sources in order to complete the necessary  clinical  trials and the  regulatory
approval processes and begin commercializing  Ampligen(R) products. There can be
no assurances  that we will raise  adequate  funds from these or other  sources,
which may have a


                                       22


material  effect on our ability to develop our products.  In addition,  if we do
not timely complete the second ISI asset  acquisition,  our financial  condition
could be materially and adversely affected (see the next risk factor).

If we do not complete the second  Interferon  Sciences  asset  acquisition,  our
ability  to  generate  revenues  from the sale of  ALFERON N  Injection  and our
financial condition will be adversely affected.

     In March,  2003 we executed two agreements with Interferon  Sciences,  Inc.
("ISI") to purchase  certain  assets of ISI. In the first  agreement we acquired
ISI's  inventory  of  ALFERON  N  Injection(R)  and a  limited  license  for the
production, manufacture, use, marketing and sale of this product. Our ability to
generate sustained revenues from sales of this product is dependent, among other
things,  on our  completing  the terms of the second  agreement  to acquire  the
balance of ISI's rights to its product as well as ISI's production facility used
to  formulate  and purify the drug  concentrate  of ALFERON N  Injection(R).  In
addition,  pursuant to the terms of the  Debentures,  we are required to acquire
ISI's  facility  within 90 days from  March 12,  2003 and,  unless  and until we
acquire the facility, $1,550,000 of the proceeds from the sale of the Debentures
has been held back.  Consummation of the second agreement requires,  among other
things,  approval by ISI's shareholders and certain environmental approvals with
regard  to the  sale  of the  facility.  As of the  date  hereof,  there  is the
possibility  that  either  or both  approvals  may not be  obtained  within  the
required 90 day period.  Our failure to complete the  acquisition  within the 90
day period  would be a  technical  default of the terms of the  Debentures  and,
absent consent from the Debenture holders for additional time, most likely would
result  in our  having  to  redeem  the  securities.  If we do not  receive  the
additional  Debenture  funds as planned  and,  especially  if we are required to
redeem the Debentures, our financial condition would be materially and adversely
affected and we would  probably have to reduce or possibly  curtail  operational
spending including some critical clinical effort.

The limited number of unissued and unreserved  authorized shares of Common Stock
severely  restricts  our  ability  to  raise  funds  through  the  sale  of  our
securities.

      We have a limited  number of shares  of Common  Stock  authorized  but not
issued or reserved  for  issuance  upon  conversion  or exercise of  outstanding
convertible and exercisable securities such as debentures, options and warrants.
As of May 1, 2003, only approximately 809,000 shares of our authorized shares of
Common  Stock will not be issued or reserved for  issuance.  Unless and until we


                                       23


are able to  increase  the  number of  authorized  shares of Common  Stock,  our
ability to raise funds through the sale of Common Stock or instruments  that are
convertible  into or exercisable  for Common Stock will be severely  restricted.
Although we intend to ask our stockholders at our next annual meeting to approve
an  amendment  to our  Certificate  of  Incorporation  to increase the shares of
Common Stock we are  authorized  to issue,  we cannot assure you that we will be
able to obtain this approval.

We have  guaranteed the value of a number of shares issued and to be issued as a
result of our acquisition of assets from Interferon Sciences. If our share price
is not above $1.59 per share 12 or 18 months  after the dates of issuance of the
guaranteed shares, our financial condition could be adversely affected.

      In March 2003 we issued  487,028  shares to Interferon  Sciences and, upon
the  completion of the second  Interferon  Sciences asset  acquisition,  we will
issue an additional  487,028  shares to Interferon  Sciences and an aggregate of
581,761 shares to two of Interferon  Sciences'  creditors.  We  anticipate,  but
cannot  assure,  that  we  will  close  the  second  Interferon  Sciences  asset
acquisition by mid June,  2003. We have  guaranteed the value of up to 1,430,817
of these  shares to be $1.59 per share or  $2,275,000  in the  aggregate  on the
relevant  termination dates. The termination dates are 18 months after the dates
of issuance of the  guaranteed  shares to ISI and GP  Strategies,  and 12 months
after the date of issuance of the guaranteed shares to the American National Red
Cross.  The  guarantee  relates only to those  shares  still held by  Interferon
Sciences and the two creditors on the applicable termination date. If, within 30
days after the  relevant  termination  date,  holders of the  guaranteed  shares
request that we honor the guarantees,  we will reacquire the holders'  remaining
guaranteed  shares  and pay the  holders  $1.59 per  share.  By way of  example,
assuming  that all 1,430,817  shares are still held on the relevant  termination
dates,  we would be  obligated  to pay to  Interferon  Sciences  and  these  two
creditors  an  aggregate of  $2,275,000.  The  reported  last sale price for our
common stock on the American Stock Exchange on May 16, 2003 was $2.84 per share.
If, during the 31 days commencing on the relevant  termination dates, the market
price of our  stock is not  above  $1.59  per  share,  we most  likely  would be
requested and obligated to pay the guaranteed  amount on the  guaranteed  shares
outstanding  on the relevant  termination  dates.  We believe that the number of
guaranteed shares still outstanding on the relevant  termination dates will be a
factor of the market  price and sales  volume of our common  stock during the 18
month period prior to the relevant termination date.

      If the holders of the guaranteed  shares do not sell a significant  amount
of their guaranteed shares prior to the relevant termination dates and the price
of our  common  stock  during  the  31 day  period  commencing  on the  relevant
termination  dates is not above $1.59 per share, we most likely will be required
to  repurchase  a  significant  number of  guaranteed  shares and our  financial
condition could be materially and adversely affected.

We may not be  profitable  unless we can  protect  our  patents  and/or  receive
approval for additional pending patents.

      We need to preserve and acquire  enforceable  patents  covering the use of
Ampligen(R) for a particular disease in order to obtain exclusive rights for the
commercial  sale of  Ampligen(R)  for such  disease.  If and when we obtain  all
rights to ALFERON N Injection,  we will need to preserve and acquire enforceable
patents covering its use for a particular  disease too. Our success depends,  in
large part,  on our ability to preserve  and obtain  patent  protection  for our
products and to obtain and preserve our trade secrets and expertise.  Certain of
our


                                       24


know-how and technology is not patentable,  particularly  the procedures for the
manufacture  of our drug  product  which are carried out  according  to standard
operating procedure manuals. We have been issued certain patents including those
on the use of Ampligen(R)  and  Ampligen(R)  in  combination  with certain other
drugs for the  treatment of HIV. We also have been issued  patents on the use of
Ampligen(R) in combination with certain other drugs for the treatment of chronic
hepatitis  B virus,  chronic  hepatitis  C virus,  and a  patent  which  affords
protection on the use of Ampligen(R) in patients with chronic fatigue  syndrome.
We have not yet been  issued any  patents  in the  United  States for the use of
Ampligen(R)  as a sole  treatment for any of the cancers which we have sought to
target.  With regard to ALFERON N  Injection,  Interferon  Sciences,  Inc. has a
patent  for  Natural  Alpha  Interferon  produced  from human  peripheral  blood
leukocytes and its production  process and has  additional  patent  applications
pending. We will acquire this patent and related patent applications if and when
we close on the second  Interferon  Sciences asset  acquisition We cannot assure
you that any of these applications will be approved or that our competitors will
not seek and obtain  patents  regarding  the use of our products in  combination
with various other agents, for a particular target indication prior to us. If we
cannot  protect our patents  covering  the use of our  products for a particular
disease,   or  obtain  additional  pending  patents,  we  may  not  be  able  to
successfully market our products.

The  patent  position  of  biotechnology  and  pharmaceutical  firms  is  highly
uncertain and involves complex legal and factual questions.

      To date,  no  consistent  policy  has  emerged  regarding  the  breadth of
protection afforded by pharmaceutical and biotechnology patents. There can be no
assurance  that new patent  applications  relating to our products or technology
will result in patents being issued or that, if issued, such patents will afford
meaningful  protection  against  competitors  with  similar  technology.  It  is
generally  anticipated that there may be significant  litigation in the industry
regarding patent and intellectual property rights. Such litigation could require
substantial  resources  from  us and we may not  have  the  financial  resources
necessary to enforce the patent  rights that we hold.  No assurance  can be made
that our patents will provide  competitive  advantages  for our products or will
not be successfully  challenged by  competitors.  No assurance can be given that
patents do not exist or could not be filed which would have a materially adverse
effect on our ability to develop or market our products or to obtain or maintain
any  competitive  position the we may achieve with respect to our products.  Our
patents also may not prevent others from developing  competitive  products using
related technology.

There can be no assurance that we will be able to obtain  necessary  licenses if
we cannot enforce  patent rights we may hold. In addition,  the failure of third
parties from whom we currently license certain proprietary information or may be
required to obtain such  licenses in the future,  to  adequately  enforce  their
rights to such proprietary information, could adversely affect the value of such
licenses to us.

      If we  cannot  enforce  the  patent  rights  we  currently  hold we may be
required to obtain  licenses from others to develop,  manufacture  or market our
products.  There can be no  assurance  that we would be able to obtain  any such
licenses on  commercially  reasonable  terms,  if at all. We  currently  license
certain proprietary  information from third parties, some of which may have been
developed  with  government  grants  under  circumstances  where the  government
maintained certain rights with respect to the proprietary information developed.
No assurances can be given that such third parties will  adequately  enforce any


                                       25


rights they may have or that the rights, if any, retained by the government will
not adversely affect the value of our license.

There is no guarantee  that our trade  secrets will not be disclosed or known by
our competitors.

      To protect our rights,  we require  certain  employees and  consultants to
enter into  confidentiality  agreements  with us. There can be no assurance that
these  agreements  will  not be  breached,  that  we  would  have  adequate  and
enforceable  remedies for any breach, or that any trade secrets of ours will not
otherwise become known or be independently developed by competitors.

If our distributors do not market our product successfully, we may not
generate significant revenues or become profitable.

      We have  limited  marketing  and sales  capability.  We need to enter into
marketing agreements and third party distribution agreements for our products in
order to generate significant revenues and become profitable. To the extent that
we  enter  into  co-marketing  or other  licensing  arrangements,  any  revenues
received by us will be dependent on the efforts of third  parties,  and there is
no assurance that these efforts will be  successful.  Our agreement with Gentiva
Health  Services  offers the  potential  to provide  significant  marketing  and
distribution  capacity  in the  United  States  while  licensing  and  marketing
agreements  with certain foreign firms should provide an adequate sales force in
South  America,  Africa,  United  Kingdom,  Australia  and New Zealand,  Canada,
Austria, Spain and Portugal.

      We cannot assure that our domestic or our foreign marketing  partners will
be able to  successfully  distribute  our  products,  or that we will be able to
establish  future  marketing  or third party  distribution  agreements  on terms
acceptable to us, or that the cost of establishing  these  arrangements will not
exceed any product  revenues.  The failure to continue these  arrangements or to
achieve other such  arrangements on  satisfactory  terms could have a materially
adverse effect on us.

No Guaranteed Source Of Required Materials.

      A number of essential  materials  are used in the  production of ALFERON N
Injection,  including  human white blood cells,  and we have a limited number of
sources from which to obtain such materials. We do not have long-term agreements
for the supply of any of such materials.  There can be no assurance we can enter
into long-term supply agreements  covering  essential  materials on commercially
reasonable  terms,  if at all.  If we are  unable to  obtain  the  required  raw
materials, we may be required to scale back our operations or stop manufacturing
ALFERON N Injection.  The costs and  availability  of products and  materials we
need for the  commercial  production of ALFERON N Injection  and other  products
which we may  commercially  produce are subject to  fluctuation  depending  on a
variety of factors beyond our control, including competitive factors, changes in
technology,  and FDA and  other  governmental  regulations  and  there can be no
assurance  that we will be able to obtain such  products and  materials on terms
acceptable to us or at all.

There is no assurance that  successful  manufacture of a drug on a limited scale
basis  for  investigational  use  will  lead  to  a  successful   transition  to
commercial, large-scale production.

         Small  changes  in  methods of  manufacturing  may affect the  chemical
structure  of  Ampligen(R)  and other RNA  drugs,  as well as their  safety  and
efficacy.  Changes


                                       26


in methods of manufacture, including commercial scale-up may affect the chemical
structure of  Ampligen(R)  and, can,  among other  things,  require new clinical
studies and affect orphan drug status, particularly, market exclusivity rights ,
if any,  under the Orphan Drug Act. The  transition  from limited  production of
pre-clinical  and clinical  research  quantities  to  production  of  commercial
quantities  of our  products  will involve  distinct  management  and  technical
challenges and will require  additional  management and technical  personnel and
capital to the extent such manufacturing is not handled by third parties.  There
can be no assurance that our manufacturing  will be successful or that any given
product  will  be  determined  to  be  safe  and  effective,  capable  of  being
manufactured economically in commercial quantities or successfully marketed.

We have limited manufacturing experience and capacity.

      Ampligen(R)  is currently  produced only in limited  quantities for use in
our clinical  trials and we are dependent upon certain third party suppliers for
key  components  of our products  and for  substantially  all of the  production
process.  The failure to continue  these  arrangements  or to achieve other such
arrangements on satisfactory  terms could have a material  adverse affect on us.
Also,  to be  successful,  our  products  must  be  manufactured  in  commercial
quantities in compliance with regulatory  requirements and at acceptable  costs.
To the extent we are involved in the production process,  our current facilities
are not adequate for the  production  of our proposed  products for  large-scale
commercialization,  and we currently do not have  adequate  personnel to conduct
commercial-scale  manufacturing.  We intend to utilize third-party facilities if
and when the need  arises  or, if we are  unable  to do so, to build or  acquire
commercial-scale   manufacturing   facilities.  We  will  need  to  comply  with
regulatory requirements for such facilities,  including those of the FDA and HPB
pertaining to current Good Manufacturing  Practices ("cGMP") regulations.  There
can be no assurance  that such  facilities  can be used,  built,  or acquired on
commercially  acceptable  terms,  or that such  facilities,  if used,  built, or
acquired, will be adequate for our long-term needs.

      The purified drug  concentrate  utilized in the  formulation  of ALFERON N
Injection  is  manufactured  in  Interferon  Science's  facility  and  ALFERON N
Injection  is  formulated  and  packaged at a  production  facility  operated by
Abbott.  if  and  when  we  close  on  the  second  Interferon   Sciences  asset
acquisition,  we will acquire  this  facility.  We still will be dependent  upon
Abbott  Laboratories  and/or  another  third party for product  formulation  and
packaging.

We may not be profitable unless we can produce  Ampligen(R) or other products in
commercial quantities at costs acceptable to us.

      We  have  never  produced  Ampligen(R)  or any  other  products  in  large
commercial  quantities.  Ampligen(R)  is currently  produced for use in clinical
trials.   We  must  manufacture  our  products  in  compliance  with  regulatory
requirements in large commercial quantities and at acceptable costs in order for
us to be  profitable.  We intend to  utilize  third-party  manufacturers  and/or
facilities  if and when the need  arises or, if we are unable to do so, to build
or acquire commercial-scale  manufacturing  facilities. If we cannot manufacture
commercial  quantities of Ampligen(R)  or enter into third party  agreements for
its manufacture at costs  acceptable to us, our operations will be significantly
affected.

Rapid technological change may render our products obsolete or non-competitive.


                                       27


      The pharmaceutical  and biotechnology  industries are subject to rapid and
substantial technological change.  Technological competition from pharmaceutical
and  biotechnology  companies,  universities,  governmental  entities and others
diversifying  into the field is intense  and is expected  to  increase.  Most of
these entities have significantly greater research and development  capabilities
than us, as well as substantial  marketing,  financial and managerial resources,
and represent  significant  competition  for us. There can be no assurance  that
developments by others will not render our products or technologies  obsolete or
noncompetitive  or  that  we will  be  able  to  keep  pace  with  technological
developments.

Our products may be subject to substantial competition.

      Ampligen(R).  Competitors may be developing  technologies  that are, or in
the future may be, the basis for competitive  products.  Some of these potential
products  may have an  entirely  different  approach  or means of  accomplishing
similar  therapeutic  effects to products being developed by us. These competing
products may be more  effective and less costly than our products.  In addition,
conventional drug therapy,  surgery and other more familiar treatments may offer
competition  to  our  products.   Furthermore,  many  of  our  competitors  have
significantly  greater  experience  than us in  pre-clinical  testing  and human
clinical trials of  pharmaceutical  products and in obtaining FDA, HPB and other
regulatory  approvals of products.  Accordingly,  our competitors may succeed in
obtaining FDA, HPB or other regulatory  product  approvals more rapidly than us.
There are no drugs approved for commercial  sale with respect to treating ME/CFS
and we have no  knowledge of any ME/CFS  drugs being  developed  by others.  The
dominant   competitors   with  drugs  to  treat  HIV  diseases   include  Gilead
Pharmaceutical,  Pfizer,  Bristol-Myers,  Abbott Labs and Schering-Plough  Corp.
("Shering").  These potential  competitors are among the largest  pharmaceutical
companies in the world, are well known to the public and the medical  community,
and have substantially  greater financial resources,  product  development,  and
manufacturing and marketing  capabilities than we have.  Although we believe our
principal  advantage is the unique mechanism action of Ampligen(R) on the immune
system, we cannot assure that we will be able to compete.

      ALFERON N Injection(R).  Many potential  competitors are among the largest
pharmaceutical  companies  in the  world,  are well  known to the public and the
medical community,  and have substantially greater financial resources,  product
development,  and manufacturing and marketing capabilities than we have. ALFERON
N Injection  currently  competes with Schering's  injectable  recombinant  alpha
interferon  product  (INTRON(R)  A) for  the  treatment  of  genital  warts.  3M
Pharmaceuticals  also  received FDA approval for its  immune-response  modifier,
Aldara(R),  a  self-administered  topical  cream,  for the treatment of external
genital and perianal  warts.  ALFERON N Injection  also competes with  surgical,
chemical,  and other  methods of treating  genital  warts.  We cannot assess the
impact products  developed by our  competitors,  or advances in other methods of
the treatment of genital warts, will have on the commercial viability of ALFERON
N Injection. If and when we obtain additional approvals of uses of this product,
we  expect  to  compete  primarily  on the  basis of  product  performance.  Our
potential  competitors have developed or may develop products (containing either
alpha or beta  interferon or other  therapeutic  compounds)  or other  treatment
modalities for those uses. In the United States,  two recombinant  forms of beta
interferon have been approved for the treatment of relapsing-remitting  multiple
sclerosis.  There can be no assurance that, if we are able to obtain  regulatory
approval of ALFERON N Injection for the treatment of new indications, we will be
able to achieve any  significant  penetration  into those markets.  In addition,


                                       28


because  certain  competitive  products  are not  dependent on a source of human
blood cells, such products may be able to be produced in greater volume and at a
lower cost than ALFERON N Injection.  Currently,  Interferon Sciences' wholesale
price on a per unit basis of ALFERON N Injection  is  substantially  higher than
that of the competitive recombinant alpha and beta interferon products.

      General.  Other companies may succeed in developing  products earlier than
we do,  obtaining  approvals for such products from the FDA more rapidly than we
do, or developing  products that are more  effective  than those we may develop.
While we will  attempt  to expand  our  technological  capabilities  in order to
remain  competitive,  there can be no assurance that research and development by
others or other  medical  advances  will not render our  technology  or products
obsolete or  non-competitive  or result in treatments  or cures  superior to any
therapy we develop.

Possible side effects from the use of Ampligen(R)  or ALFERON N Injection  could
adversely effect potential revenues and  physician/patient  acceptability of our
product.

      Ampligen(R). We believe that Ampligen(R) has been generally well tolerated
with a low  incidence  of clinical  toxicity,  particularly  given the  severely
debilitating  or life  threatening  diseases  that  have  been  treated.  A mild
flushing  reaction has been observed in approximately 15% of patients treated in
our various studies. This reaction is occasionally  accompanied by a rapid heart
beat,  a tightness  of the chest,  urticaria  (swelling  of the skin),  anxiety,
shortness of breath,  subjective  reports of "feeling hot," sweating and nausea.
The reaction is usually infusion-rate related and can generally be controlled by
slowing the infusion rate. Other adverse side effects include liver enzyme level
elevations,  diarrhea, itching, asthma, low blood pressure,  photophobia,  rash,
transient visual  disturbances,  irregular heart rate, decreased visual activity
in  platelets  and  white  blood  cell  counts,  anemia,  dizziness,  confusion,
elevation of kidney function tests,  occasional  temporary hair loss and various
flu-like  symptoms,  including fever,  chills,  fatigue,  muscular aches,  joint
pains,  headaches,  nausea and vomiting.  These flu-like side effects  typically
subside within several  months.  One or more of the potential side effects might
deter usage of Ampligen(R) in certain clinical  situations and therefore,  could
adversely effect potential revenues and  physician/patient  acceptability of our
product.

      ALFERON N Injection(R).  At present,  ALFERON N Injection is only sold for
the  intralesional  (with in the lesion)  treatment of  refractory  or recurring
external genital warts in adults. In clinical trials conducted for the treatment
of genital warts with ALFERON N Injection,  patients did not experience  serious
side effects; however, there can be no assurance that unexpected or unacceptable
side  effects  will not be found in the future  for this use or other  potential
uses of  ALFERON N  Injection  which  could  threaten  or limit  such  product's
usefulness.

We may be subject to product  liability  claims from the use of  Ampligen(R)  or
other of our products which could negatively affect our future operations.

      We face an inherent  business risk of exposure to product liability claims
in the event that the use of  Ampligen(R)  or other of our  products  results in
adverse  effects.  This  liability  might  result from  claims made  directly by
patients,  hospitals, clinics or other consumers, or by pharmaceutical companies
or others  manufacturing these products on our behalf. Our future operations may


                                       29


be negatively  effected from the litigation costs,  settlement expenses and lost
product  sales  inherent to these  claims.  While we will continue to attempt to
take appropriate  precautions,  we cannot assure that we will avoid  significant
product  liability  exposure.  Although we currently  maintain product liability
insurance  coverage,  there can be no assurance that this insurance will provide
adequate  coverage  against  product  liability  claims.  A  successful  product
liability claim against us in excess of our $1,000,000 in insurance  coverage or
for which coverage is not provided could have a negative  effect on our business
and financial condition.

The loss of Dr. Carter's services could hurt our chances for success.

      Our success is dependent on the continued efforts of Dr. William A. Carter
because of his  position as a pioneer in the field of nucleic  acid  drugs,  his
being  the  co-inventor  of  Ampligen(R),  and  his  knowledge  of  our  overall
activities,  including  patents,  clinical  trials.  The  loss  of Dr.  Carter's
services could have a material  adverse effect on our operations and chances for
success. While we have an employment agreement with Dr. Carter, and have secured
key man life  insurance  in the amount of $2 million on the life of Dr.  Carter,
the loss of Dr. Carter or other personnel,  or the failure to recruit additional
personnel  as needed could have a  materially  adverse  effect on our ability to
achieve our objectives.

Uncertainty of health care reimbursement for our products.

      Our ability to  successfully  commercialize  our products will depend,  in
part,  on the extent to which  reimbursement  for the cost of such  products and
related  treatment  will be  available  from  government  health  administration
authorities,   private  health  coverage   insurers  and  other   organizations.
Significant  uncertainty exists as to the reimbursement status of newly approved
health care products,  and from time to time legislation is proposed,  which, if
adopted,   could  further   restrict  the  prices   charged  by  and/or  amounts
reimbursable to  manufacturers  of  pharmaceutical  products.  We cannot predict
what,  if any,  legislation  will  ultimately  be  adopted or the impact of such
legislation  on us.  There  can  be no  assurance  that  third  party  insurance
companies will allow us to charge and receive  payments for products  sufficient
to realize an appropriate return on our investment in product development.

There are  risks of  liabilities  associated  with  handling  and  disposing  of
Hazardous materials.

      Our  business   involves  the  controlled  use  of  hazardous   materials,
carcinogenic  chemicals and various radioactive  compounds.  Although we believe
that our safety  procedures for handling and disposing of such materials  comply
in  all  material   respects  with  the   standards   prescribed  by  applicable
regulations, the risk of accidental contamination or injury from these materials
cannot be completely eliminated. In the event of such an accident or the failure
to comply with applicable  regulations,  we could be held liable for any damages
that result,  and any such liability  could be  significant.  We do not maintain
insurance coverage against such liabilities.

The market price of our stock may be adversely affected by market volatility.

The market price of our common  stock has been and is likely to be volatile.  In
addition to general  economic,  political and market  conditions,  the price and


                                       30


trading volume of our stock could fluctuate  widely in response to many factors,
including:

      o     announcements  of  the  results  of  clinical  trials  by us or  our
            competitors;

      o     adverse reactions to products;

      o     governmental approvals, delays in expected governmental approvals or
            withdrawals  of  any  prior  governmental  approvals  or  public  or
            regulatory agency concerns  regarding the safety or effectiveness of
            our products;

      o     changes in U.S. or foreign  regulatory  policy  during the period of
            product development;

      o     developments in patent or other  proprietary  rights,  including any
            third party challenges of our intellectual property rights;

      o     announcements of technological innovations by us or our competitors;

      o     announcements  of  new  products  or  new  contracts  by us  or  our
            competitors;

      o     actual or anticipated variations in our operating results due to the
            level of development expenses and other factors;

      o     changes in financial  estimates by  securities  analysts and whether
            our earnings meet or exceed the estimates;

      o     conditions and trends in the pharmaceutical and other industries;

      o     new accounting standards; and

      o     the  occurrence  of  any of  the  risks  described  in  these  "Risk
            Factors."

      Our common stock is listed for quotation on the American  Stock  Exchange.
For the 12-month  period ended  December 31, 2002, the price of our common stock
has  ranged  from $0.74 to $4.95.  We expect  the price of our  common  stock to
remain  volatile.  The average daily  trading  volume in our common stock varies
significantly.  Our  relatively  low average  volume and low  average  number of
transactions  per day may affect the ability of our  stockholders  to sell their
shares in the public  market at  prevailing  prices and a more active market may
never develop.

In the  past,  following  periods  of  volatility  in the  market  price  of the
securities of companies in our industry,  securities class action litigation has
often been instituted  against companies in our industry.  If we face securities
litigation in the future, even if without merit or unsuccessful, it would result
in  substantial  costs and a diversion of management  attention  and  resources,
which would negatively impact our business.

Our stock price may be adversely  affected if a significant amount of shares are
sold in the public market.

      As of May 1,  2003,  approximately  834,445  shares of our  common  stock,
constituted  "restricted securities" as defined in Rule 144 under the Securities
Act of 1933. In addition,  we are registering 5,967,820 shares issuable upon the
conversion of 135% of the Debentures and as payment of interest thereon.  All of
these  shares  are  being  registered  in the  form S-3  registration  statement
discussed  above  pursuant to  agreements  between us and the  purchasers in our
recent  private  placements,  requiring  us to register  their shares for resale
under the Securities  Act. This permits the sale of registered  shares of common
stock  in the  open  market  or in  privately  negotiated  transactions  without
compliance with the requirements of Rule 144. In addition, as of May 1, 2003, we
had  options and  warrants  outstanding  for the  purchase  of an  aggregate  of
approximately  9,710,035 shares of our common stock,  which includes 135% of the
shares issuable upon exercise of the Warrants.  To the extent the exercise price
of the options and warrants is less than the market  price of the common  stock,


                                       31


the holders of the options and warrants are likely to exercise them and sell the
underlying  shares of common stock and to the extent that the  conversion  price
and exercise price of these  securities are adjusted  pursuant to  anti-dilution
protection,  the securities  could be  exercisable or convertible  for even more
shares of common  stock.  Moreover,  we  anticipate  that we will be issuing and
registering for public resale 1,068,789 shares if and when we acquire additional
assets from Interferon Sciences, Inc. and, possibly,  additional shares to raise
funding or compensate employees,  consultants and/or directors. We are unable to
estimate  the amount,  timing or nature of future  sales of  outstanding  common
stock.  Sales of  substantial  amounts of our common stock in the public  market
could cause the market price for our common stock to  decrease.  Furthermore,  a
decline in the price of our common  stock  would  likely  impede our  ability to
raise capital through the issuance of additional shares of common stock or other
equity securities.

Provisions of our Certificate of Incorporation and Delaware law could defer a
change of our management, which could discourage or delay offers to acquire us.

      Provisions of our Certificate of  Incorporation  and Delaware law may make
it more difficult for someone to acquire  control of us or for our  stockholders
to remove existing management,  and might discourage a third party from offering
to acquire us, even if a change in control or in management  would be beneficial
to our stockholders.  For example, our Certificate of Incorporation allows us to
issue  shares of  preferred  stock  without  any vote or  further  action by our
stockholders.  Our Board of Directors has the authority to fix and determine the
relative rights and preferences of preferred  stock. Our Board of Directors also
has the authority to issue preferred stock without further stockholder approval.
As a result,  our Board of Directors could authorize the issuance of a series of
preferred  stock that would grant to holders the  preferred  right to our assets
upon  liquidation,  the right to receive dividend  payments before dividends are
distributed  to the holders of common stock and the right to the  redemption  of
the  shares,  together  with a premium,  prior to the  redemption  of our common
stock. In this regard,  in November,  2002 we adopted a shareholder  rights plan
and, under the Plan, our Board of Directors declared a dividend  distribution of
one Right for each  outstanding  share of Common Stock to stockholders of record
at the close of business on November 29,  2002.  Each Right  initially  entitles
holders to buy one unit of preferred stock for $30.00.  The Rights generally are
not transferable  apart from the common stock and will not be exercisable unless
and until a person or group  acquires or commences a tender or exchange offer to
acquire,  beneficial ownership of 15% or more of our common stock.  However, for
William A. Carter,  M.D., our chief executive  officer,  who already  beneficial
owns 11.4% of the our common stock, the Plan's threshold will be 20%, instead of
15%.  The Rights will expire on November  19,  2012,  and may be redeemed  prior
thereto at $.01 per Right under certain circumstances.

      Because the risk factors  referred to above could cause actual  results or
outcomes  to differ  materially  from  those  expressed  in any  forward-looking
statements  made  by us,  you  should  not  place  undue  reliance  on any  such
forward-looking  statements.  Further, any forward-looking statement speaks only
as of the date on which it is made and we undertake no  obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the  date on  which  such  statement  is  made  or  reflect  the  occurrence  of
unanticipated  events.  New  factors  emerge  from  time to time,  and it is not
possible for us to predict which will arise.  In addition,  we cannot assess the
impact of each  factor on our  business  or the extent to which any  factor,  or
combination of factors, may cause actual results to differ materially from those
contained in any  forward-looking  statements.  Our research in clinical efforts
may continue for the next several  years and we may continue to incur losses due
to clinical  costs


                                       32


incurred in the development of Ampligen(R) for commercial application.  Possible
losses may fluctuate  from quarter to quarter as a result of  differences in the
timing of  significant  expenses  incurred and receipt of licensing  fees and/or
cost recovery treatment revenues in Europe, Canada and in the United States.

ITEM 2.  Properties.

We currently  lease and occupy a total of  approximately  18,850  square feet of
laboratory  and  office  space in two  states  and some  office  space in Paris,
France. Our headquarters is located in Philadelphia,  Pennsylvania consisting of
a suite of offices of  approximately  15,000 square feet. We also lease space of
approximately  3,850  square  feet  in  Rockville,   Maryland  for  research  of
development,  our pharmacy,  packaging,  quality  assurance and quality  control
laboratories,  as well as additional  office space.  Approximately  2,000 square
feet are dedicated to the  pharmacy,  packaging,  quality  assurance and control
functions.  The Company  believes  that its Rockville  facilities  will meet its
requirements,  for planned clinical trials and treatment protocols, through 2004
and  possibly  longer  after  which time it may need to increase  its  Rockville
facilities   either   through   third   parties  or  by  building  or  acquiring
commercial-scale facilities.

We  currently  occupy  and use the New  Brunswick,  New  Jersey  Laboratory  and
Production  Facility  owned by ISI. We are in the process of acquiring  title to
these  facilities  pursuant to our second asset  acquisition  agreement with ISI
(see Financial and Asset  Acquisition  in Item 1 above for more  details).  This
acquisition  consists of two buildings  located on 2.8 acres.  One Building is a
two story  facility  consisting of a total of 31,300 square feet.  This facility
has  offices,  laboratories  production  space,  and  shipping  receiving  area.
Building two has 11,670  square feet  consisting  of offices,  laboratories  and
warehouse space. The property has parking space for approximately 100 vehicles.

We also  have a 24.9%  interest  in  Ribotech,  Ltd.  located  in South  Africa.
Ribotech was  established  by  Bioclones to develop and operate a  manufacturing
facility.  Manufacturing at the pilot facility commenced in 1996. We expect that
Ribotech will start construction on a new commercial  production facility in the
future, although no assurance can be given that this will occur. The Company has
no obligation to fund this construction.  Our interest in Ribotech,  is a result
of the marketing and manufacturing agreement executed with Bioclones in 1994.

ITEM 3.  Legal Proceedings.

On September  30,  1998,  we filed a  multi-count  complaint  against  Manuel P.
Asensio,  Asensio & Company,  Inc.  ("Asensio").  The action  included claims of
defamation,  disparagement,  tortuous interference with existing and prospective
business  relations  and  conspiracy,  arising  out of the  Asensio's  false and
defamatory  statements.  The complaint  further alleged that Asensio defamed and
disparaged  us  in  furtherance  of  a  manipulative,   deceptive  and  unlawful
short-selling  scheme in August and September,  1998. In 1999,  Asensio filed an
answer and  counterclaim  alleging  that in  response to  Asensio's  strong sell
recommendation  and other press releases,  we made defamatory  statements  about
Asensio. We denied the material  allegations of the counterclaim.  In July 2000,
following dismissal in federal court for lack of subject matter jurisdiction, we
transferred  the action to the  Pennsylvania  State  Court.  In March 2001,  the


                                       33


defendants  responded  to the  complaints  as amended and a trial  commenced  on
January 30, 2002. A jury verdict  disallowed  the claims  against the defendants
for defamation and  disparagement and the court granted us a directed verdict on
the  counterclaim.  On July 2, 2002 the Court entered an order granting us a new
trial against  Asensio for defamation  and  disparagement.  Thereafter,  Asensio
appealed the granting of a new trial. This appeal is now pending in the Superior
Court of Pennsylvania.

In June 2002, a former  ME/CFS  clinical  trial  patient and her husband filed a
claim in the Superior Court of New Jersey,  Middlesex County, against us, one of
our clinical trial  investigators and others alleging that she was harmed in the
ME/CFS  clinical trial as a result of negligence  and breach of  warranties.  We
believe the claim is without  merit and we are  defending  the claim  against us
through our product liability insurance carrier.

In June 2002, a former ME/CFS clinical trial patient in Belgium filed a claim in
Belgium, against Hemispherx Biopharma Europe, NV/SA, our Belgian subsidiary, and
one of our  clinical  trial  investigators  alleging  that she was harmed in the
Belgium  ME/CFS  clinical  trial  as  a  result  of  negligence  and  breach  of
warranties. We believe the claim is without merit and we are defending the claim
against us through our product liability insurance carrier.

In July 2002, we filed suit in the United States  District Court for the Eastern
District of Pennsylvania  against Federal Insurance Company  ("Federal") seeking
(1) a judicial order  declaring our rights and the  obligations of Federal under
the  insurance  policy  Federal  sold to us (2)  monetary  damage  for breach of
contract  resulting from Federal's refusal to fully defend us in connection with
the Asensio  litigation  (3) monetary  damages to  compensate  us for  Federal's
breach  of its  fiduciary  duty  faith and  dealing  and (4)  monetary  damages,
interest,  costs, and attorneys fees to compensate us for Federal's violation of
the Pennsylvania Bad Faith Statute. On March 31, 2003 we settled our outstanding
claim with our  insurance  company  relating  to  reimbursement  of  expenses in
connection   with  our  Asensio  law  suits.   The  net  settlement   amount  of
approximately   $1,050,000   is  recorded   as  a   reduction   in  General  and
Administrative  expenses  in our  statement  of  operations  for the year  ended
December 31, 2002.

In March 2003, the law firm of Schnader,  Harrison,  Segal & Lewis,  LLP filed a
complaint in the Court of Common  Pleas of  Philadelphia  County  against us for
alleged legal fees in the sum of $65,051.  We believe the claim is without merit
and we are defending the claim.

ITEM 4.  Submission of Matters to a Vote of Security Holders.
No matters  were  submitted to a vote of the  security  holders  during the last
quarter of the year ended December 31, 2002.

PART II

ITEM 5.  Market for Registrant's Common Equity and Related Stockholder Matters.

In the year 2002,  we acquired  27,500 shares of common stock on the open market
at an  average  cost of $1.82 per  share.  The  acquisition  of the  shares  was
authorized under a stock buy-back program authorized by the board of directors.


                                       34


In fiscal 2002, we issued  11,300 new shares of common stock to warrant  holders
exercising  non-public  warrants  at an  average  exercise  price of $3.30.  The
warrants  exercised were granted by us in the period covering 1993 through 1996.
In addition, we issued 48,392 shares in settlement of debt of $154,000.

In  addition,  as  discussed in greater  detail in "RECENT  FINANCING  AND ASSET
ACQUISITIONS" above in Item 1. Business, we 1) issued convertible debentures and
warrants to two  investors  for cash,  we issued  shares to ISI for  assets,  2)
issued  shares to an affiliate of Esteve in exchange for  convertible  preferred
equity certificates of our Luxembourg  subsidiary and 3) we plan to issue shares
of  common  stock  to ISI and to two  creditors  of ISI for  additional  assets.
Cardinal  Securities  LLC was placement  agent on the sale of the Debentures and
Warrants  and  received a placement  fee equal to 7% of the  proceeds  from that
offering  (up to 1.75% of which is payable in Company  Common  Stock) and common
stock purchase  warrants to purchase 25,000 shares for each $1,000,000  received
by the Company.

The foregoing issuances of securities were private  transactions and exempt from
registration  under section 4(2) of the Securities Act and/or  regulation D rule
506 promulgated under the Securities Act.

Since  October 1997 our common  stock and Class A warrants  have been listed and
traded on the American Stock  Exchange  ("AMEX") under the symbol HEB and HEBws,
respectively.  The Class A Warrants  expired on November 2, 2001.  The following
table sets forth the high and low list prices for our Common  Stock for the last
two fiscal  years and the first  quarter of fiscal 2003 as reported by the AMEX.
Such prices reflect  inter-dealer  prices,  without retail markup,  markdowns or

As of March 27,  2003  there  were  approximately  259  holders of record of our
Common  Stock.  This  number  was  determined  from  records  maintained  by the
Company's transfer agent and does not include beneficial owners of the Company's
securities  whose  securities  are held in the names of various  dealers  and/or
clearing agencies.

As of April 4, 2003,  the last sale  price for our common  stock on the AMEX was
$1.35 per share.


                                       35


We have not paid any  dividends  on our  Common  Stock in  recent  years.  It is
management's  intention not to declare or pay dividends on our Common Stock, but
to retain  earnings,  if any, for the  operation  and expansion of the Company's
business.

The following table gives  information about our Common Stock that may be issued
upon the  exercise  of  options,  warrants  and  rights  under all of our equity

ITEM 7. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations.

The following  discussion and analysis is related to our financial condition and
results  of  operations  for the three  years  ended  December  31,  2002.  This
information  should be read in  conjunction  with Item 6 -  "Selected  Financial
Data" and our  consolidated  financial  statements  and  related  notes  thereto
beginning on F-1 of this Form 10-K/A.

Statement of Forward-Looking Information

Certain statements in the section are "forward-looking  statements".  You should
read  the   information   before  Part  I  above,   "Special   Note"   Regarding
Forward-Looking  Statements"  for more  information  about our  presentation  of
information.

Background

We have  reported net income only from 1985 through  1987.  Since 1987,  we have
incurred,  as  expected,  substantial  operating  losses  due to our  conducting
clinical  testing.  Prior to completing an Initial  Public  Offering  ("IPO") in
November 1995, we financed operations primarily through the private placement of
equity and debt  securities,  equipment  lease  financing,  interest  income and
revenues  from  licensing,   royalty  agreements  and  cost  recovery  treatment
programs.

We have established a strong  foundation of laboratory,  pre-clinical  data with
respect to the  development  of nucleic  acid to enhance the  natural  antiviral
defense system of the human body and the development of the therapeutic products


                                       37


for the  treatment  of chronic  disease.  Our strategy is to obtain the required
regulatory approval which will allow the progressive introduction of Ampligen(R)
(our proprietary drug) for treating Myalgic  encephalomyelitis  Chronic Syndrome
(ME/CFS"), HIV, hepatitis C ("HCV") and hepatitis B ("HBV") in the U.S., Canada,
Europe and Japan.  Ampligen(R) is currently in phase III clinical  trials in the
U.S. for use in  treatment of ME/CFS and is in Phase IIb Clinical  trials in the
U.S. for the treatment of newly emerged  multi-drug  resistant  HIV, and for the
induction of Cell mediated immunity in HIV patients that are under control using
potentially toxic drug cocktail.

Our proprietary drug technology  utilizes  specifically  configured  ribonucleic
acid ("RNA") and is protected by more than 350 patents  worldwide.  With over 80
additional patent application pending to provide further proprietary  protection
in  various  international  markets.   Certain  patents  apply  to  the  use  of
Ampligen(R)  alone  and  certain  patent  apply  to the  use of  Ampligen(R)  in
combination with certain other drugs. Some composition of matter patents pertain
to other new medication, which have a similar mechanism of action.

In March, 2003, the Company acquired from Interferon Sciences Inc. ("ISI"),  all
of ISI's raw  materials,  work-in-progress  and  finished  product  of Alferon N
Injection(R),  together with a limited license for the production,  manufacture,
use, marketing and sale of the product. Alferon N Injection(R) [interferon alfa-
n3 (human  derived)] is a natural alpha interferon that has been approved by the
U.S. Food and Drug Administration  ("FDA") for commercial sale for the treatment
of  certain  types of genital  warts.  We intend to market  this  product in the
United State through sales  facilitated  via third party  marketing  agreements.
Additionally, we intend to implement studies, beyond those conducted by ISI, for
testing the  potential  treatment  of HIV,  Hepatitis  C and other  indications,
including  multiple  sclerosis.  This acquisition not withstanding,  our primary
focus  remains  the  development  to  Ampligen(R)  for  treating  ME/CFS and HIV
diseases.

We are  incorporated in Maryland in 1996 under the name HEM research,  Inc., and
originally served as a supplier of research support  products.  Our business was
redirected in the early 1980's to the development of nucleic acid pharmaceutical
technology and the  commercialization  of RNA drugs. We were  reincorporated  in
Delaware  and  changed  our  name to Hem  Pharmaceutical  Corp.  in 1991  and to
Hemispherx  Biopharma,  Inc., in June 1995. We have three domestic  subsidiaries
BioPro  Corp.,  BioAegean  Corp.,  and Core  BioTech  Corp.,  all of  which  are
incorporated in Delaware.  Our foreign subsidiaries include Hemispherx Biopharma
Europe N.V./S.A.  established in Belgium in 1998 and Hemispherx Biopharma Europe
S.A. incorporated in Luxembourg in 2002.

Result of Operations

Years Ended December 31, 2002 vs. 2001

Net loss

Our net loss was  approximately  $7,424,000 for the year ended December 31, 2002
versus a net loss of $9,083,000  in 2001.  Per share losses in 2002 was 23 cents
versus a per  share  loss of 29 cents in 2001.  This  year to year  decrease  in
losses of  $1,659,000  is  primarily  due to higher  revenues and lower costs in
2002.  Revenues  were up  $514,000  in 2002  and  total  expenses  were  down by
$2,231,000  offset by a write down in the carrying  value of our  investments in
the amount of $1,366,000 for a net cost decrease of $865,000.


                                       38


Revenues

Our  revenues  have  come  from our  ME/CFS  cost  recovery  treatment  programs
principally  underway in the U.S.,  Canada and Europe.  These clinical  programs
allow us to  provide  Ampligen(R)  therapy at our cost to  severely  debilitated
ME/CFS patients. Under this program the patients pay for the cost of Ampligen(R)
doses infused.  These costs total approximately  $7,200 for a 24 weeks treatment
program. Revenues from cost recovery treatment programs totaled some $341,000 in
2002. In 2001, these revenues were $390,000 or 14% higher than 2002 revenues. We
expected  revenues  in the U.S.  to  decline  due to the  focus of our  clinical
resources on  conducting  and  completing  the AMP 516 ME/CFS Phase III clinical
trial as well as the  start up of the AMP 719 and AMP 720 HIV  clinical  trials.
The clinical  data  collected  from  treating  patients  under the cost recovery
treatment  programs will augment and  supplement  the data collected in the U.S.
Phase III ME/CFS trial.

 We  received a  licensing  fee of 625,000  Euros  (some  $563,000)  from Esteve
pursuant to a sales and  distribution  agreement in which Esteve was granted the
exclusive  right to market  Ampligen(R)  in Spain,  Portugal and Andorra for the
treatment  of ME/CFS in turn we  provided  to Esteve  technical  scientific  and
commercial information. The agreement terms require no additional performance by
us. Our total  revenues,  including  this  licensing  fee, in 2002 was  $904,000
compared to revenues of $390,000 in 2001.

Revenues for  non-refundable  license fees are recognized  under the performance
method.  This method  recognizes  revenue to the extent of  performance  to date
under a licensing agreement.  In computing earned revenue, it considers only the
amount of  non-refundable  cash actually received to date. This method considers
future  payments to be  contingent  and thus ignores the  possibility  of future
milestone  payments  when  computing  the amount of revenue  earned in a current
period.

Research and Development costs

Our strategy is to develop our lead compound, the experimental immunotherapeutic
Ampligen(R),  to treat chronic diseases for which there is currently no adequate
treatment available. We seek the required regulatory approval,  which will allow
the  commercial  introduction  of Ampligen  for ME/CFS and HIV/AIDS in the U.S.,
Canada, Europe and Japan.

Ampligen is currently  being tested in a Phase III clinical  trial, in the U.S.,
for use in treatment of ME/CFS,  the so-called  AMP-516 study.  Ampligen is also
currently  in two  Phase  IIb  studies  for  the  treatment  of HIV to  overcome
multi-drug resistance, virus mutation and toxicity associated with current HAART
therapies.  One study, the AMP-719, is a Salvage Therapy,  conducted in the U.S.
and  evaluating  the  potential  synergistic  efficacy of Ampligen in multi-drug
resistant HIV patients for immune enhancement. The second study, the AMP-720, is
a clinical  trial  designed to evaluate the effect of Ampligen  under  Strategic
Treatment Intervention and is also conducted in the U.S.

AMP 516

As of December, 2002 the study was fully enrolled and we have patients in excess
of the full enrollment in order to potentially  compensate for "drop outs". More
than 230 patients have been  randomized into the trial and we expect to complete
dosing the  current  group by the end of 2003.  The next stage of the program is
final data collection,  quality assurance of the data to insure its accuracy and


                                       39


analysis of the data  according to regulatory  guidelines to facilitate  the New
Drug Application  (NDA),  expected to be filed in the first or second quarter of
2004. The date of potential  commercial  approval depends on whether the Company
receives  Fast  Track  Status or not by the FDA.  In case of Fast  Track the FDA
approval  time is maximum six months.  If the Company is not granted  Fast Track
Designation,  the approval time can take substantially longer,  depending on the
progress  made by the FDA in  review of the  application.  The FDA may deny full
commercial  approval to the drug at any time,  including after Fast Track Status
has been awarded.

Expenses  related to the  ME/CFS  Phase III are  expected  to  decrease  in 2003
because  of fewer  patients  to be treated as the trial  nears  completion.  The
remaining  patients are treated at only two  investigational  sites, which makes
data collection and monitoring more cost effective.  Accordingly,  the estimated
cost  for  completion  of  the  study  and  data  analysis  is  estimated  to be
approximately $500,000 to $600,000. In the event significant numbers of patients
were to prematurely  leave the clinical trial,  any potential FDA approval of an
NDA could be indefinitely  delayed which would have a materially  adverse effect
on the  Company's  ability to receive  potential  revenues in the next 2-3 years
from this therapeutic indication.

As with any  experimental  drug being tested for use in treating human diseases,
the FDA must approve the testing and clinical protocols employed and must render
their  decision  based on the safety  and  efficacy  of the drug  being  tested.
Historically  this is a long and costly  process.  Our  ME/CFS AMP 516  clinical
study is a Phase III study, which based on favorable results,  will serve as the
basis for us to file a new drug application with the FDA. The FDA review process
could take 18-24 months and result in one of the following  events;  1) approval
to market  Ampligen(R)  for use in treating  ME/CFS  patients,  2) required more
research,  development,  and  clinical  work,  3_  approval to market as well as
conduct more testing,  or 4) reject our application.  Given these variables,  we
are unable to project  when  material  net cash inflows are expected to commence
from the sale of Ampligen(R).

AMP 719 and AMP 720

As of December 2002 approximately 55 patients have been enrolled in both studies
combined and they are being treated in  approximately  10 different active sites
around the U.S. The Company  expects the enrollment in these clinical  trials to
accelerate as we recruit more investigators based on the open-label analysis and
presentation of promising results in Prague, Barcelona, Spain and Naples.

The  length  of the  study  and the  costs  related  to these  trials  cannot be
determined at this time as it will be materially influenced by (a) the number of
clinical  investigators  needed to fulfill the required number of patients,  (b)
the rate of  accrual  of  patients  and (c) the  retention  of  patients  on the
protocol  and  their  adherence  to the  protocol  requirements.  Under  optimal
conditions,  the  out  of  pocket  cost  of  completing  the  studies  could  be
approximately $3 million. The rate of enrollment depends on patient availability
and on other products being in clinical trials for the treatment of HIV, because
there could be competition  for the same patient  population.  At present,  more
than 18 FDA approved drugs for HIV treatment may compete for available patients.
The  length,  and  subsequently  the  expense  of these  studies,  will  also be
determined by an analysis of the interim data by the FDA, which will decide when
completion of the ongoing Phase IIb is appropriate and whether a Phase III trial
will have to be conducted  or not. In case of Phase III study is  required;  the
FDA might  require a patient  population


                                       40


exceeding  the current one which will  influence the cost and time of the trial.
Accordingly,  the number of  "unknowns"  is  sufficiently  great to be unable to
predict when, or whether, the Company may obtain revenues from its HIV treatment
indications.

Our  overall  research  and  development  direct  costs in 2002 were  $4,946,000
compared to direct  research and  development  costs in 2001 of  $5,780,000  and
$6,136,000 in 2000. We estimate that 80% of these  expenditures to be related to
our ME/CFS research and development and 20% related to our HIV studies.

General and Administrative Expenses

Excluding stock compensation expense,  general and administrative  expenses were
approximately  $1,882,000  in 2002 versus  $2,741,000  in 2001.  This decease in
expenses of $859,000 in 2002, is due to several  factors  including the recovery
of certain legal expenses of  approximately  $1,050,000  relating to the Asensio
lawsuit from our insurance  carrier and lower overall legal expenses due to less
litigation, partially offset by higher Insurance premiums.

Stock compensation  expenses was $133,000 or $538,000 lower than recorded in the
year 2001. The  compensation  reflects the imputed  non-cash expense recorded to
reflect the cost of warrants granted to outside parties for services rendered to
the Company.

Equity Loss-Unconsolidated Affiliates

During  the three  months  ended  June 2002 and  December  2002,  we  recorded a
non-cash  charge of $678,000  and  $396,000  respectively,  to  operations  with
respect to our $1,074,000  investment in R.E.D. These charges were the result of
our determination that R.E.D.'s business and financial position had deteriorated
to the point  that our  investment  had been  permanently  impaired.  Please see
"RESEARCH AND  DEVELOPMENT/COLLABORATIVE  AGREEMENTS" in Part 1 for more details
on these transactions.

In May 2000,  we  acquired  an  equity  interest  in  Chronix  Biomedical  Corp.
("CHRONIX").  for  $700,000.  During the quarter  ended  December 31,  2002,  we
recorded a noncash charge of $292,000 with respect to our investment in Chronix.
This  impairment  reduces our carrying  value to reflect a permanent  decline in
Chronix's market value based on their current proposed equity offerings.  Please
see  "RESEARCH  AND  DEVELOPMENT/COLLABORATIVE  AGREEMENTS"  in Part 1 for  more
details on these transactions.

In April, 1999 we acquired a 30% equity position in the California  Institute of
Molecular  Medicine ("CIMM") for $750,000.  During the fourth quarter of 2001 we
recorded a non-cash  charge of $485,000 with respect to our  investment in CIMM.
This was a result  of our  determination  that  CIMM's  operations  have not yet
evolved to the point where the full carrying  value of our  investment  could be
supported based on that Company's financial position and operating results. This
amount  represented the unamortized  balance of goodwill included as part of our
investment.  During 2002, CIMM continued to suffer  significant losses resulting
in a deterioration of its financial  condition.  The $485,000 written off during
2001  represented the un-amortized  balance of goodwill  included as part of the
Company's  investment.   Additionally,  during  2001  the  Company  reduced  its
investment  in  CIMM  based  on its  percentage  interest  in  CIMM's  continued
operating  losses.  The Company's  remaining  investment at December 12, 2002 in


                                       41


CIMM,  representing a 30% interest in CIMM's equity at such date, was completely
written off during 2002. Such amount was not material.

These charges are reflected in the  Consolidated  Statements of Operations under
the caption "Equity loss in unconsolidated  affiliate." Please see "RESEARCH AND
DEVELOPMENT/COLLABORATIVE  AGREEMENTS"  in  Part 1 for  more  details  on  these
transactions.

Other Income/Expense

Interest and other income totaled $103,000 in 2002 compared to $284,000 recorded
in 2001.  Significantly  lower interest rates on money market accounts and lower
cash available for investment basically account for the difference. All funds in
excess of our immediate need are invested in short term high quality securities,
which earned much lower interest income in 2002.

Years Ended December 31, 2001 vs. 2000

Net loss

We reported a net loss of  approximately  $9,083,000 for the year ended December
31, 2001 versus a net loss of  approximately  $8,552,000  for the year 2000. The
increase in losses of $531,000 in 2001 was  basically  due to lower  ME/CFS Cost
Recovery  Treatment  Revenues  and  Interest  Income.  In addition we recorded a
non-operating,  non-cash  charge of $485,000 with respect to our  investments in
unconsolidated  affiliates.  This amount  represents the unamortized  balance of
Goodwill included in the investments.  Overall  operating  expenses in 2001 were
$639,000 lower than operating  expenses  experienced in 2000. Our loss per share
was $0.29 in 2001 and 2000.

Revenues

At this time, (prior to the acquisition of Alferon N) our revenues come from our
ME/CFS cost recovery treatment programs principally underway in the U.S., Canada
and Europe.  These clinical programs allow us to provide  Ampligen(R) therapy at
our cost to  severely  debilitated  ME/CFS  patients.  Under  this  program  the
patients  pay for the cost of  Ampligen(R)  doses  infused.  These  costs  total
approximately  $7,200  for a 24 weeks  treatment  program.  Revenues  from  cost
recovery  treatment  programs  totaled  some  $788,000 in 2000.  In 2001,  these
revenues  declined  by  $398,000  or 51%.  We  expected  revenues in the U.S. to
decline due to the focus of our clinical  resources on conducting and completing
the AMP516  ME/CFS Phase III  clinical  trial as well as the start up of the AMP
719 and AMP 720 HIV clinical  trials.  Revenues  from the European cost recovery
treatment  programs  were  lower than  expected  primarily  due to our  European
investigators  spending  a great deal of time in  reviewing  and  analyzing  the
clinical data  collected in the  treatment of some 150 patients in Belgium.  The
clinical data collected from treating patients under the cost recovery treatment
programs will augment and  supplement  the data  collected in the U.S. Phase III
ME/CFS trial.

Research and Development costs

As  previously  noted,  our research and  development  is primarily  directed at
developing  our lead  product,  Ampligen(R),  as a therapy  for use in  treating
various  chronic  illnesses  as well as cancer.  In 2000 and 2001,  most of this
effort was directed toward  conducting and supporting  clinical trials involving
patients  affected with ME/CFS.  Our research and development  direct costs were
$5,780,000 in 2001 compared to $6,136,000  spent in 2000. The lower research and
development


                                       42


costs basically reflect the net sum of less costs related to lower cost recovery
treatment  revenues and lower  expenses  related to the ME/CFS  clinical  trials
offset by increased purchases of polymers and increased expenses relating to the
HIV trials  initiated  in 2001.  As to be  expected,  costs  related to the cost
recovery  treatment  programs  were  down  approximately  $275,000  due to lower
revenues  recorded  in 2001.  Also  expenses  relating  to the ME/CFS  Phase III
clinical trial were down some $863,000 in 2001 versus 2000 due to fewer patients
being treated in the cost-intensive segment of the program as the clinical trial
nears  completion.  This clinical  trial is a  multicenter,  placebo-controlled,
randomized,  double  blind study to evaluate the efficacy and safety of treating
230  ME/CFS  patients  with  Ampligen(R).  As of  February  2002,  more than 220
patients have been enrolled.  These lower costs relating to our ME/CFS  programs
were partially  offset by an increase in polymer  purchase in 2001 in the amount
of $317,000 and an increase  due to spending on the new HIV clinical  trials now
underway.  The  polymer  purchase  increase  was  needed  to  boost  our on hand
inventory  for the  production  of  Ampligen(R).  The HIV  clinical  trials were
initiated to evaluate  the use of  Ampligen(R)  in concert with other  antiviral
drugs in treating  patients  severely  afflicted  with AIDS. We expect levels of
these  clinical  trials  to  continue  throughout  2002.  (See  Part  I,  Item 1
"BUSINESS" for more information on our Research and Development for programs.)

General and Administrative Expenses

Excluding stock compensation expense,  general and administrative  expenses were
approximately  $2,741,000  in 2001 versus  $3,298,000  in 2000.  The decrease in
expense is primary due to lower professional fees in 2001. All other general and
administrative  expenses  were  slightly  less  than  recorded  in  2000.  Stock
compensation expenses were $671,000 or some $274,000 higher than recorded in the
year 2000. The  compensation  reflects the imputed  non-cash expense recorded to
reflect the cost of warrants granted to outside parties for services rendered to
the Company.

Equity Loss-Unconsolidated Affiliates

During the fourth  quarter of 2001,  we  recorded a non-cash  charge of $485,000
with respect to our  investment in CIMM. The amount  represents the  unamortized
balance of  goodwill  included as part of our  investment.  This was a result of
management's  determination  that CIMM's  operations  had not yet evolved to the
point where our full carrying value of its investment  could be supported  based
on their financial position and operating results.

Other Income/Expense

Interest  and other  income of  $284,000  in 2001 was  lower  than the  $572,000
recorded in 2000.  Significantly  lower interest rates on money market  accounts
and lower cash available for investment  basically  account for the  difference.
All  funds in excess  of our  immediate  need are  invested  in short  term high
quality securities, which earned much lower interest income in 2001.

Liquidity And Capital Resources

Cash,  cash  equivalents  and short term  investments  at December 31, 2002 were
approximately  $2,811,000.  Cash  used  for  operating  activities  in 2002  was
$6,409,000. Additional uses of cash included expenditures of $176,000 for patent
acquisition cost, and $50,000 to acquire 27,500 shares of our stock.


                                       43


Cash proceeds from  financing  activities in 2002 were  approximately  $961,000.
$65,000 was received from stock subscriptions and $946,000 was received from the
issuance of preferred equity certificates of our European subsidiary.

Our net operating cash "burn rate" for the last three months of fiscal year 2002
approximated  $547,000  per month or  $6,564,000  on an  annualized  basis.  All
clinical trial drug supplies  produced in 2002 were fully expensed although some
costs are  expected to be  recovered  under the  expanded  access cost  recovery
programs  authorized  by FDA and  regulatory  bodies  in  other  countries.  Our
operating cash "burn rate" should decline in 2003 as the AMP 516 ME/CFS clinical
trial nears completion and the cost of European market  development  activity is
reduced.

On March 20, 2002, our European  subsidiary  Hemispherx  Biopharma Europe,  S.A.
("Hemispherx  S.A.")  entered  into a  sales  and  Distribution  agreement  with
Laboratories  Del Dr.  Esteve  S.A.  ("Esteve").  Pursuant  to the  terms of the
agreement,  Esteve was  granted the  exclusive  right to market  Ampligen(R)  in
Spain,  Portugal  and  Andorra  for the  treatment  of  Myalgic/Chronic  Fatigue
Syndrome  ("ME/CFS").  In addition to other terms and other projected payments.,
Esteve paid an initial and  non-refundable  fee of 625,000 Euros  (approximately
$563,000)  to  Hemispherx  S.A.  on April  24,  2002.  Esteve is to pay a fee of
1,000,000 Euros after U.S. Food and Drug Administration  approval of Ampligen(R)
for the treatment of ME/CFS and a fee of 1,000,000  Euros upon Spain's  approval
of the final marketing  authorization for using Ampligen(R) for the treatment of
ME/CFS.

Also Esteve purchased 1,000,000 Euros of Hemispherx S.A.'s convertible preferred
equity  certificates.  These  securities  paid  a 7%  dividend  and  were  to be
converted into .00114% of the  outstanding  common stock of Hemispherx S.A. upon
the  earlier  of the  completion  of an  initial  public  offering  ("IPO") on a
European  stock  exchange or September  30, 2003.  However,  at our request,  on
January 9, 2003, Esteve agreed to convert the preferred equity certificates into
shares of our common stock and, on March 13, 2003, we issued  347,445  shares of
our common stock to Provesan  SA, an  affiliate  of Esteve,  in exchange for the
1,000,000 Euros of convertible preferred equity certificates owned by Esteve. We
agreed to register the shares issued to Provesan SA and we have registered these
shares for public sale.

On March 12, 2003, we issued an aggregate of  $5,426,000 in principal  amount of
6% Senior  Convertible  Debentures  due March 2005 and an  aggregate of $743,288
warrants to two investors in a private placement for aggregate anticipated gross
proceeds of $4,650,000.  Pursuant to the terms of the Debentures,  $1,550,000 of
the  proceeds  from the sale of the  Debentures  have been held back and will be
released  to us if,  and  only  if,  we  acquire  ISI's  facility  with in a set
timeframe (see the discussion  below). The Debentures mature on January 31, 2005
and bear  interest at 6% per annum,  payable  quarterly  in cash or,  subject to
satisfaction  of certain  conditions,  common stock.  Any shares of common stock
issued to the  investors  as payment of  interest  shall be valued at 95% of the
average closing price of the common stock during the five  consecutive  business
days ending on the third  business  day  immediately  preceding  the  applicable
interest  payment  date.  Pursuant  to the terms and  conditions  of the  Senior
Convertible  Debentures,  we have  pledged  all of our  assets,  other  than our
intellectual  property,  as  collateral  and are subject to comply with  certain
financial  and  negative  covenants,  which  include  but are not limited to the
repayment of principal balances upon achieving certain revenue milestone.

The  Debentures  are  convertible  at the  option of the  investors  at any time
through


                                       44


January 31, 2005 into shares of our common stock. The conversion price under the
Debentures is fixed at $1.46 per share,  subject to adjustment for anti-dilution
protection   for  issuance  of  common  stock  or  securities   convertible   or
exchangeable into common stock at a price less than the conversion price then in
effect.

The investors  also  received  Warrants to acquire at any time through March 12,
2008 an  aggregate  of  743,288  shares of common  stock at a price of $1.68 per
share.  On March 12, 2004,  the exercise price of the Warrants will reset to the
lesser of the  exercise  price then in effect or a price equal to the average of
the daily price of the common  stock  between  March 13, 2003 and March 11, 2004
(but in no event less than $1.176 per share).  The exercise price (and the reset
price)  under  the  Warrants  also  is  subject  to  similar   adjustments   for
anti-dilution protection.

We entered into a registration rights agreement with the investors in connection
with the issuance of the Debentures and the Warrants.  The  registration  rights
agreement  requires  that we register the shares of common stock  issuable  upon
conversion of the  Debentures,  as interest  shares under the Debenture and upon
exercise  of the  Warrants.  In  accordance  with  this  agreement,  we  filed a
registration  statement on form S-3 with the Securities and Exchange Commission.
The investors include Portside Growth & Opportunity Fund Ltd. and Leonardo, L.P.
the  Debentures  mature on March 12,  2005 and bear  interest  at 6% per  annum,
payable  quarterly in cash or common stock. Any shares of common stock issued to
the  investors  as payment  of  interest  shall be valued at 95% of the  average
closing  price of the common stock  during the five  consecutive  business  days
ending on the third business day immediately  preceding the applicable  interest
payment date.

On March 11, 2003,  we acquired from  Interferon  Sciences,  Inc.  ("ISI") ISI's
inventory  of ALFERON N  Injection(R),  a  pharmaceutical  product  used for the
treatment  of certain  types of genital  warts,  and a limited  license  for the
production,  manufacturing,  use, marketing and sale of this product. As partial
consideration,  we issued 487,028 shares of our common stock to ISI. Pursuant to
our  agreements  with ISI, we are in the process of  registering  the  foregoing
shares for public sale.

On March 11, 2003, we also entered into an agreement to purchase from ISI all of
its rights to the product and other assets related to the product including, but
not limited to, real estate and machinery.  For these assets,  we have agreed to
issue to ISI an  additional  487,028  shares  and to issue  314,465  shares  and
267,296  shares,  respectively  to  the  American  National  Red  Cross  and  GP
Strategies Corporation,  two creditors of ISI. The Company also will be required
to satisfy real estate taxes and utility  expenses of ISI which totaled $520,751
as of December 31, 2002 and which are secured by a lien on the real estate to be
acquired by the Company.  We have  guaranteed the market value of all but 62,500
of  these  share  on  terms  substantially  similar  to  those  for the  initial
acquisition of the ISI assets.

As of December 31, 2002, we had approximately  $2,811,000 in cash and short term
investments.  We believe  that these funds plus 1) the  anticipated  infusion of
approximately  $4.4 million in net proceeds  from the  debenture  placement,  2)
projected  net cash flow from the  acquisition  of the ALFERON N business and 3)
the funds  received from the insurance  settlement  should be sufficient to meet
our operating  requirement during the next 12 months.  Also, we have the ability
to  curtail   discretionary   spending,   including   research  and  development
activities, if required to conserve cash.


                                       45


Because of our long-term capital requirements,  we may seek to access the public
equity  market  whenever  conditions  are  favorable,  even if we do not have an
immediate need for additional  capital at that time. Any additional  funding may
result in significant dilution and could involve the issuance of securities with
rights,  which are senior to those of  existing  stockholders.  We may also need
additional  funding  earlier than  anticipated,  and our cash  requirements,  in
general, may vary materially from those now planned, for reasons including,  but
not limited to,  changes in our  research  and  development  programs,  clinical
trials,  competitive and technological  advances,  the regulatory  process,  and
higher  than  anticipated  expenses  and lower than  anticipated  revenues  from
certain of our clinical  trials for which cost  recovery from  participants  has
been approved.

                          NEW ACCOUNTING PRONOUNCEMENTS

      In January 2003, the FASB issued  Interpretation No. 46, "Consolidation of
Variable  Interest  Entities"  ("Interpretation  No. 46"),  that  clarifies  the
application  of  Accounting  Research  Bulletin No. 51,  Consolidated  Financial
Statements,  "to certain  entities  in which  equity  investors  do not have the
characteristics  of a controlling  financial  interest or do not have sufficient
equity at risk for the  entity to  finance  its  activities  without  additional
subordinated  financial  support from other  parties.  Interpretation  No. 46 is
applicable  immediately for variable interest entities created after January 31,
2003. For variable  interest entities created to January 31, 2003, the provision
of Interpretation  No. 46 are applicable no later than July 1, 2003. The Company
does not  expect  this  Interpretation  to have an  effect  on the  consolidated
financial statements.

      In August 2001, the FASB issued  Statement No. 143,  "Accounting for Asset
Retirement Obligation" ("SFAS 143"), which provides the accounting  requirements
for retirement  obligation  associated with tangible long-lived assets. SFAS 143
requires  entities  to  record  the  fair  value of the  liability  for an asset
retirement obligation in the period in which it is incurred and is effective for
the Company's 2003 fiscal year. The adoption of SFAS 143 is not expected to have
a material impact on the Company's consolidated results of operations, financial
position or cash flows.

      In October 2001, the FASB issued  Statement No. 144,  "Accounting  for the
Impairment or Disposal of Long-lived  Assets"  ("SFAS 144").  SFAS 144 addresses
financial  accounting and reporting for the impairment or disposal of long-lived
assets.  This statement  supersedes SFAS Statement No. 121,  "Accounting for the
Impairment of Long-Lived  Assets and for Long-Lived  Assets to Be Disposed Of, "


                                       46


and the accounting and reporting provision of APB Opinion No. 30, "Reporting the
Results  of  Operations-Reporting  the  Effects  of  Disposal  of a Segment of a
Business,  and  Extraordinary,  Unusual and  Infrequently  Occurring  Events and
transactions.  "This new pronouncement also amends Accounting  Research Bulletin
(ARB) No. 51 "Consolidated Financial Statements,  "to eliminate the exception to
consolidation for a subsidiary for which control is likely to be temporary. SFAS
144  required  that one  accounting  model be used for  long-lived  assets to be
disposed of by sale, whether previously held and used or newly acquired and also
broadens the  presentation  of  discontinued  operation to include more disposal
transactions.  SFAS 144 is effective for fiscal years  beginning  after December
15, 2001 and interim periods within those fiscal years.  Adoption of SFAS 144 on
January 1, 2002, did not have impact on the Company's financial  position,  cash
flows or results of operation for the year ended December 31, 2002.

      In June 2002,  the FASB issued  Statement  No. 146,  "Accounting  for Cost
Associated  with Exit or Disposal  Activities"  ("SFAS  146"),  which  addresses
financial  accounting and reporting for costs  associated  with exit or disposal
activities,  and nullifies Emerging Task Force (EITF) Issue No. 94-3, "Liability
Recognition for Certain  Employee  termination  Benefits and Other Costs to Exit
and  Activity  (including  Certain  Costs  Incurred in a  Restructuring)"  which
previously governed the accounting treatment for restructuring activities.  SFAS
146 applies to costs  associated  with an exit activity that does not involve an
entity  newly  acquired  in a business  combination  or with  disposal  activity
covered by SFAS 144. Those costs include, but are not limited to, the following:
(1) termination  benefits  provide to current  employees that are  involuntarily
terminated under the terms of a benefit  arrangement that, in substance,  is not
an ongoing benefit arrangement or individual deferred-compensation  contract,(2)
costs to  terminate  a contract  that is not a capital  lease,  and (3) costs to
consolidated facilities or relocated employees. SFAS 146 does not apply to costs
associated  with the  retirement of long-lived  assets covered by SFAS 143. SFAS
146  will be  applied  prospectively  and is  effective  for  exit  or  disposal
activities after December 31, 2002.

      In December  2002,  the FASB issued  Statement  No. 148,  "Accounting  for
Stock-Based  Compensation-Transition  and  Disclosure",  and  amendment  of FASB
Statement No. 123 ("SFAS").  SFAS 148 amends FASB Statement No. 123,  Accounting
for Stock-Based Compensation, to provide alternative method of transition for an
entity  that  voluntarily  changes to the fair  value  based of  accounting  for
stock-based employee  compensation.  It also amends the disclosure provisions of
that Statement to require prominent disclosure about the effects on reported net
income of an entity's  accounting  policy  decisions with respect to stock-based
employee  compensation.  Finally,  this Statement amends  Accounting  Principles
Board ("APB") Opinion No. 28, Interim Financial  Reporting to require disclosure
about those effects in interim financial information.  SFAS 148 is effective for
financial  statements  for fiscal  years ending  after  December  15, 2002.  The
Company  will  continue  to  account  for  stock-based  compensation  using  the
intrinsic  value method of APB Opinion No. 25,  "Accounting  for Stock Issued to
Employees, "but has adopted the enhance disclosure requirements of SFAS 148 (See
Note 10).

Critical Accounting Policies

      Financial  Reporting  Release No. 60., which was recently  released by the
Securities  and  Exchange  Commission,  requires  all  companies  to  include  a
discussion of critical  accounting policies or method used in the preparation of
financial statements. Our significant accounting policies are described in Notes
to the Consolidated  Financial Statements.  The significant  accounting policies
that we believe are most  critical to aid in fully  understanding  our  reported


                                       47


financial results are the following:

Revenue

      Revenues  for  non-refundable   license  fees  are  recognized  under  the
performance  method. This method recognizes revenue to the extent of performance
to date under a licensing  agreement.  In computing earned revenue, it considers
only the amount of  non-refundable  cash actually  received to date. This method
considers  future  payments to be contingent and thus ignores the possibility of
future  milestone  payments  when  computing  the amount of revenue  earned in a
current period.

      Revenue  from  the  sale  of  Ampligen(R)  under  cost  recovery  clinical
treatment protocols approved by the FDA is recognized when treatment is provided
to the patient.

Patents and Trademarks

      Effective  October 1, 2001, we adopted a 17 year estimated useful life for
the amortization of our patents and trademark rights in order to more accurately
reflect  their useful life.  Prior to October 1, 2001,  we were using a ten year
estimated useful life.

      Patents and trademarks are stated at cost  (primarily  legal fees) and are
amortized  using the  straight  line  method  over the life of the  assets.  The
Company  reviews its patents and  trademark  rights  periodically  to  determine
whether  they have  continuing  value.  Such review  includes an analysis of the
patent and  trademark's  ultimate  revenue  and  profitability  potential  on an
undiscounted   cash  basis  to  support  the  realizability  of  its  respective
capitalized cost. In addition, management's review addresses whether each patent
continues to fit into Company's strategic business plans.

Research and Developments Costs

      Research and development costs are direct costs related to both future and
present  products  and are  charged  to  operations  as  incurred.  The  Company
recognized   research  and  development  costs  of  $6,136,000   $5,780,000  and
$4,946,000 in 2000, 2001 and 2002 respectively.

Use of Estimates

      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 for the reporting
period. Actual results could differ from those estimates.

ITEM 7a. Quantitative and Qualitative Market Risk.

Market Risk

     We had $2.8 million in cash, cash equivalents and short term investments at


                                       48


December 31, 2002. To the extent that our cash and cash  equivalents  exceed our
near term funding requirements, the excess cash was invested in three (3) to six
(6) month high quality financial instruments. We employ established policies and
procedures to manage any risks with respect to any investment exposure.

ITEM 8.  Financial Statements and Supplementary Data.

      The consolidated  balance sheets as of December 31, 2001 and 2002, and our
consolidated statements of operations, changes in stockholders' equity (deficit)
and  comprehensive  loss and cash  flows for each of the years in the three year
period ended December 31, 2002,  together with the reports of BDO Seidman,  LLP,
independent  public  accountants,  are  included  at  the  end of  this  report.
Reference is made to the "Index to Financial  Statements and Financial Statement
Schedule" on page F-1.

ITEM  9.  Changes  in and  Disagreements  with  Accountants  on  Accounting  and
          Financial Disclosures.

None.

securities,  to  file  reports  with  the  Securities  and  Exchange  Commission
reflecting  their  initial  position  of  ownership  on  Form 3 and  changes  in
ownership  on Form 4 or Form 5.  Based  solely on a review of the copies of such

all applicable Section 16(a) filing requirements on a timely basis.

Code of Ethics

Our Board of Directors have not yet adopted a Code of Ethics that would apply to

Employment Agreements

      Hemispherx entered into an amended and restated employment  agreement with
its President and Chief Executive  Officer,  Dr. William A. Carter,  dated as of
December 3, 1998,  which  provided  for his  employment  until May 8, 2004 at an
initial  base  annual  salary of  $361,586,  subject  to  annual  cost of living
increases.  In addition, Dr. Carter could receive an annual performance bonus of
up to 25% of his base salary,  at the sole discretion of the board of directors.
Dr. Carter will not participate in any discussions  concerning the determination
of his annual bonus.  Dr. Carter is also entitled to an incentive  bonus of 0.5%
of the gross proceeds received by Hemispherx from any joint venture or corporate
partnering  arrangement,  up to an aggregate maximum incentive bonus of $250,000
for all such transactions.  Dr. Carter's agreement also provides that he be paid
a base  salary and  benefits  through  May 8, 2004 if he is  terminated  without
"cause",  as that term is defined in the agreement.  This agreement was extended
to


                                       56


May 8, 2008. Pursuant to his original  agreement,  as amended on August 8, 1991,
Dr. Carter was granted options to purchase 73,728 shares of Hemispherx's  common
stock at an exercise price of $2.71 per share.

      Hemispherx entered into an amended and restated engagement  agreement with
Robert  E.  Peterson  dated  April 1, 2001  which  provides  for Mr.  Peterson's
employment as Hemispherx's Chief Financial Officer until December 31, 2003 at an
annual  base  salary of  $155,988  per year,  subject  to annual  cost of living
increases.  In addition,  Mr.  Peterson  shall receive bonus  compensation  upon

Peterson also received  200,000 warrants to purchase shares of common stock with

attended.  Committee chairmen each receive an additional  retainer of $5,000 per
year and  committee  members each receive an  additional  retainer of $3,000 per
year. All non-employee  directors received some compensation in 2001 for special
project work performed on behalf of Hemispherx.  All directors have been granted
options to purchase  common  stock  under  Hemispherx's  1990 Stock  Option Plan
and/or Warrants to purchase common stock.  Hemispherx believes such compensation
and  payments  are  necessary  in order for  Hemispherx  to  attract  and retain
qualified outside directors.

1993 Stock Option Plan

      Hemispherx's 1993 Stock Option Plan ("1993 Plan"),  provides for the grant
of options for the purchase of up to an  aggregate  of 138,240  shares of common
stock to Hemispherx's employees, directors, consultants and others whose efforts
are important to the success of Hemispherx. The 1993 Plan is administered by the
Compensation Committee of the board of directors,  which has complete discretion
to select the  eligible  individuals  to receive and to  establish  the terms of
option grants.  The 1993 Plan provides for the issuance of either  non-qualified
options or incentive  stock options,  provided that incentive stock options must
be granted with an exercise price of not less than fair market value at the time
of  grant  and that  non-qualified  stock  options  may not be  granted  with an
exercise  price of less than 85% of the fair market  value at the time of grant.
The number of shares of common stock  available for grant under the 1993 Plan is
subject to adjustment for changes in capitalization.  This plan terminates as of
July 7, 2003. To date, no options have been granted under the 1993 Plan.

1992 Stock Option Plan

      Hemispherx's 1992 Stock Option Plan ("1992 Plan"),  provides for the grant
of options for the  purchase of up to an  aggregate  of 92,160  shares of common
stock to Hemispherx's employees, directors, consultants and others whose efforts
are important to the success of Hemispherx. The 1992 Plan is administered by the
Compensation Committee of the board of directors,  which has complete discretion
to select the  eligible  individuals  to receive and to  establish  the terms of
option grants.  The 1992 Plan provides for the issuance of either  non-qualified
options or incentive  stock options,  provided that incentive stock options must
be granted with an exercise price of not less than fair market value at the time
of  grant  and that  non-qualified  stock  options  may not be  granted  with an
exercise  price of less than


                                       57


50% of the fair  market  value at the time of  grant.  The  number  of shares of
common stock  available  for grant under the 1992 Plan is subject to  adjustment
for changes in  capitalization.  This plan  expired as of  December 3, 2002.  No
options were granted under the 1992 Plan.

1990 Stock Option Plan

Hemispherx's 1990 Stock Option Plan, as amended ("1990 Plan"),  provides for the
grant of options to employees,  directors, officers, consultants and advisors of
Hemispherx  for the purchase of up to an  aggregate of 460,798  shares of common
stock. The 1990 plan is administered by the Compensation  Committee of the board
of directors,  which has complete  discretion to select eligible  individuals to
receive and to  establish  the terms of option  grants.  The number of shares of
common stock  available  for grant under the 1990 Plan is subject to  adjustment
for changes in  capitalization.  As of December 31, 2001,  options to acquire an
aggregate of 154,535  shares of the common stock were available for grants under
the 1990 plan.  This plan  remains in effect  until  terminated  by the Board of
Directors or until all options are issued.

401(K) Plan

In December 1995, Hemispherx  established a defined contribution plan, effective
January 1, 1995,  entitled the Hemispherx  Biopharma  employees  401(K) Plan and
Trust  Agreement.  All  full  time  employees  of  Hemispherx  are  eligible  to
participate  in the 401(K) plan  following  one year of  employment.  Subject to
certain  limitations  imposed by federal tax laws,  participants are eligible to
contribute up to 15% of their salary (including bonuses and/or  commissions) per
annum.  Participants'  contributions  to  the  401(K)  plan  may be  matched  by
Hemispherx  at a rate  determined  annually  by the  board  of  directors.  Each
participant immediately vests in his or her deferred salary contributions, while
Hemispherx  contributions  will vest over one year. In 2002 Hemispherx  provided
matching  contributions  to each employee for up to 6% of annual pay for a total
of $38,000 for all employees.

Compensation Committee Interlocks and Insider Participation

      During  the  fiscal  year  ended   December  31,  2002,   the  members  of
Hemispherx's  Compensation Committee were Ransom W. Etheridge and Richard Piani.
Mr. Etheridge serves as the Company's Secretary and he is an attorney in private
practice and has rendered  legal  services to Hemispherx for which he received a
fee. Mr. Piani received fees for certain  consulting work performed in Europe on
behalf of the  Company.  Refer to Item 13.  "Certain  Relationships  and Related
Transactions" for more information.

Compensation Committee Report on Compensation

The  Compensation  Committee  makes  recommendations   concerning  salaries  and
compensation for employees of and consultants to Hemispherx.

The  following  report of the  compensation  committee  discusses  our executive
compensation  policies and the basis of the  compensation  paid to our executive
officers in 2002.

In general,  the compensation  committee seeks to link the compensation  paid to
each  executive  officer to the  experience  and  performance  of such executive
officer. Within these parameters, the executive compensation program attempts to
provide an overall  level of executive  compensation  that is  competitive  with
companies   of   comparable   size


                                       58


and with similar market and operating characteristics.

There are three elements in Hemispherx executive total compensation program, all
determined by individual  and corporate  performance as specified in the various
employment   agreements;   base  salary,  annual  compensation,   and  long-term
incentives.

Base Salary

The Summary Compensation Table shows amounts earned during 2002 by our executive
officers.  The base  compensation of such executive  officers is set by terms of
the  employment  agreement  entered into with each such executive  officer.  The
Company  established the base salaries for Chief Executive Officer,  Dr. William
A.  Carter  under an  employment  agreement  in  December 3, 1998 (as amended on
August 14,  2003),  which  provides  for a base salary of $361,586  until May 8,
2008.  Also we entered  into an  extended  employment  agreement  with Robert E.
Peterson,  Chief Financial  Officer for a base salary of $155,988 until December
31, 2003.  Dr.  Carter and Mr.  Peterson's  agreements  allow for annual cost of
living increases.  Dr. Carter's compensation also includes funds previously paid
to Dr.  Carter by  Hahneman  Medical  University  where he served as a professor
until 1998. This  compensation  was continued by the Company and totaled $79,826
in each of 2000 and 2001, and $82,095 in 2002.

Annual Incentive

Our Chief Executive  Officer and our Chief Financial  Officer are entitled to an
annual incentive bonus as determined by the compensation committee based on such
executive  officers'  performance  during the previous  calendar  year. The cash
bonus  awarded to the  company's  Chief  Executive  Officer in 1999 and 2000 was
determined based on this provision of his employment agreement.

               Report of Independent Certified Public Accountants

The Board of Directors and Stockholders
Hemispherx Biopharma, Inc.

      We have audited the accompanying consolidated balance sheets of Hemispherx
Biopharma,  Inc. and  subsidiaries  as of December 31, 2001 and 2002 the related
consolidated  statements  of  operations,  changes in  stockholders'  equity and
comprehensive  (loss) and cash  flows for each of the three  years in the period
ended  December  31,  2002.  These  consolidated  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

      We conducted our audits in accordance  with auditing  standards  generally
accepted in the United States of America.  Those standards  require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

      In our opinion,  the consolidated  financial  statements referred to above
present fairly, in all material  respects,  the financial position of Hemispherx
Biopharma,  Inc.  and  subsidiaries  as of  December  31,  2001 and 2002 and the
results of their  operations and their cash flows for each of the three years in
the period ended  December 31, 2002 in  conformity  with  accounting  principles
generally accepted in the United States of America.

BioAegean  Corp.  and Core BioTech Corp.  which were  incorporated  in September
1994, and are inactive,  and  Hemispherx  Biopharma-Europe  N.V./S.A.  which was
incorporated  in  1998  and  Hemispherx   Biopharma   Europe  S.A.,   which  was
incorporated during 2002. All significant intercompany balances and transactions
have been  eliminated  in  consolidation.  The Company also has  investments  in
unconsolidated  affiliates  which are accounted for on the equity or cost method
of accounting (see note 2c).

On March 11, 2003,  we acquired from  Interferon  Sciences,  Inc.  ("ISI") ISI's
inventory  of ALFERON N  Injection(R),  a  pharmaceutical  product  used for the
treatment  of certain  types of genital  warts,  and a limited  license  for the
production,  manufacturing,  use, marketing and sale of this product. As partial
consideration,  we issued 487,028 shares of our common stock to ISI. Pursuant to
our  agreements  with ISI, we are in the process of  registering  the  foregoing
shares for public sale.  Except for 62,500 of the shares  issued to ISI, we have
guaranteed the market value of the shares retained by ISI through March 11, 2005
to be $1.59 per share.

On March 11, 2003, we also entered into an agreement to purchase from ISI all of
its rights to the product and other assets related to the product including, but
not limited to, real estate and  machinery.  This  purchase is  contingent on us
receiving appropriate Governmental approval for the real estate transaction. For
these assets, we have agreed to issue to ISI an additional 487,028 shares and to
issue 314,465 shares and 267,296  shares,  respectively to two creditors of ISI.
The Company will be required to satisfy other liabilities of ISI which aggregate
approximately  $521,000 and which are secured by a lien on ISI's real estate. We
have  guaranteed  the market  value of all but  62,500 of these  shares on terms
substantially similar to those for the initial acquisition of the ISI assets.

We will account for these transactions as a Business Combination under Statement
of  Financial  Accounting  Standards  ("SFAS") No. 141  Accounting  for Business
Combinations.

On May 1, 1997,  the Company  received  permission  from the U.S.  Food and Drug
Administration ("FDA") to recover the cost of Ampligen(R) from patients enrolled
in the Company's  AMP-511  ME/CFS  open-label  treatment  protocol.  The cost of
Ampligen(R)  to the patient is $2,100 for the first eight weeks of treatment and
$2,400 for each additional eight-week period thereafter.

In 1998,  the Company  initiated the  recruitment of clinical  investigators  to
enroll   ME/CFS   patients   in  the   confirmatory   Phase  III  double   blind
placebo-controlled  clinical  study of  Ampligen(R).  This  clinical  trial  was
approved by the


                                      F-8


FDA in 1998 and is designed to test the safety and  efficiency of Ampligen(R) in
treating ME/CFS.

The ME/CFS Cost Recovery  Treatment  Program in Belgium was started in 1994 with
the approval of the Belgian Regulatory  authorities.  Since its inception,  over
150 patients have  participated in this program.  Clinical data collected in the
treatment  of  these  ME/CFS  patients  will be used to  support  the  Company's
European  Medical  Evaluation  Agency ("EMEA") Drug Approval  Application and in
applications in other  regulatory  jurisdictions.  A similar program underway in
Austria is undergoing expansion.

(2) Summary of Significant Accounting Policies

(a) Cash and Cash Equivalents

Cash equivalents consist of money market  certificates and overnight  repurchase
agreements collateralized by money market securities with original maturities of
less than  three  months,  with  both a cost and fair  value of  $2,552,000  and
$1,404,000 at December 31, 2001 and 2002, respectively.

(b) Short-term Investments

Investments  with original  maturities of more than three months and  marketable
equity securities are considered available for sale. The investments  classified
as available for sale include debt securities and equity  securities  carried at
estimated  fair value of  $5,310,000  and $555,000 at December 31, 2001 and 2002
respectively.  The  unrealized  gains and losses are  recorded as a component of
shareholders' equity.

(c) Investments in unconsolidated affiliates

Investments in Companies in which the Company owns 20% or more and not more than
50% are accounted for using the equity method of accounting.

Investments in Companies in which the Company owns less than 20% of and does not
exercise a  significant  influence  are  accounted  for using the cost method of
accounting.

In 1998, the Company  invested  $1,074,000 for a 3.3% equity  interest in R.E.D.
Laboratory ("R.E.D.").  R.E.D. is a privately held biotechnology company for the
development of diagnostic markers for Chronic Fatigue Syndrome and other chronic
immune  diseases.  We have a research  collaboration  agreement  with R.E.D.  to
assist in this development.  R.E.D. is headquartered in Belgium.  The investment
was  recorded at cost.  During the three months ended June 30, 2002 and December
31, 2002 we recorded non-cash charges of $678,000 and $396,000 respectively,  to
operations  with  respect to our  investment  in R.E.D.  These  charges were the
result of our determination  that R.E.D.'s  business and financial  position had
deteriorated to the point that our investments had been permanently impaired.

In April, 1999 we acquired a 30% equity position in the California  Institute of
Molecular  Medicine  ("CIMM")  for  $750,000  and  entered  into a research  and
development arrangement.  CIMM'S research is focused on developing therapies for
use in  treating  patients  affected by  Hepatitis C ("HCV").  We use the equity
method of accounting with respect to this investment.  During the fourth quarter
of 2001 we recorded a non-cash charge of $485,000 with respect to our investment
in CIMM. This was a result of our determination  that CIMM's operations have not
yet evolved to the point where the full carrying value of our  investment  could
be supported based on that company's  financial  position and operating results.


                                      F-9


During  2002,  CIMM  continued  to  suffer  significant  losses  resulting  in a
deterioration of its financial  condition.  The $485,000 written off during 2001
represented  the  unamortized  balance  of  goodwill  included  as  part  of the
Company's  investment.   Additionally,  during  2001  the  Company  reduced  its
investment  in  CIMM  based  on its  percentage  interest  in  CIMM's  continued
operating  losses.  The Company's  remaining  investment at December 31, 2001 in
CIMM,  representing  its 30%  interest  in CIMM's  equity at such date,  was not
deemed to be permanently  impaired but was  completely  written off during 2002.
Such amount was not material.  These  charges are reflected in the  Consolidated
Statements  of  Operations  under the  caption  "Equity  loss in  unconsolidated
affiliates".  We still  believe  CIMM will  succeed in their  efforts to advance
therapeutic  treatment  of HCV. We believe  that CIMM's  Hepatitis C  diagnostic
technology  has great  promise  and  fills a  long-standing  global  void in the
collective  abilities  to diagnose  and treat  Hepatitis C infection at an early
stage of the disorder.

The  Company's  investment  in Ribotech,  Ltd. is also  accounted  for using the
equity method of accounting.  The Company  received  24.9% of Ribotech,  Ltd. as
partial compensation under the license agreement described in note 10. Ribotech,
Ltd.  has incurred  net losses  since  inception.  The Company does not share in
those losses in accordance with the licensing  agreement and is not obligated to
fund such losses. The net investment in Ribotech is zero as of December 31, 2001
and 2002.  During 2000, the Company prepaid  $500,000 to Ribotech,  Ltd. for raw
material purchases. $110,000 of materials were delivered in 2000 and the balance
of $390,000 was applied towards the purchase of materials during 2001.

Investments in  unconsolidated  affiliates also includes an equity investment in
Chronix  Biomedical  ("Chronix").   Chronix  focuses  upon  the  development  of
diagnostics  for chronic  diseases.  The initial  investment was made in May 31,
2000 through the issuance of 50,000 shares of Hemispherx Biopharma,  Inc. common
stock from the  treasury.  On October 12, 2000 an  additional  50,000  shares of
common  stock  were  issued  from  the  treasury  for  a  total   investment  of
approximately $678,000. During 2001 additional common stock plus cash were given
to Chronix for a total  investment  at  $700,000.  The  percentage  ownership in
Chronix is  approximately  5.4% and is  accounted  for under the cost  method of
accounting.  During the quarter  ended  December 31, 2002, we recorded a noncash
charge of $292,000 with respect to our  investment in Chronix.  This  impairment
reduces our carrying  value to reflect a permanent  decline in Chronix's  market
value based on their current proposed investment offerings.

Pursuant to a strategic  alliance  agreement,  the Company provided Chronix with
$250,000  during 2000 to conduct  research in an effort to develop  intellectual
property on potential new products for diagnosing and treating  various  chronic
illnesses  including chronic fatigue syndrome.  The strategic alliance agreement
provides the Company certain  royalty rights with respect to certain  diagnostic
technology  developed from this research and a right of first refusal to license
certain  therapeutic  technology  developed from this  research.  The payment of
$250,000 was charged to research and development expense during 2000.

                                      F-10


Property and equipment consists of furniture,  fixtures,  office equipment,  and
leasehold improvements and is recorded at cost. Depreciation and amortization is
computed using the  straight-line  method over the estimated useful lives of the
respective  assets,   ranging  from  five  to  seven  years.   Depreciation  and
amortization expense was $131,000, $127,000 and $91,000 for 2000, 2001 and 2002,
respectively. In 2002, fully depreciated equipment in the amount of $418,000 and
fully depreciated leasehold improvements in Europe in the amount of $12,000 were
written-off due to the closing of European offices.

(e) Patent and Trademark Rights

Effective  October 1, 2001, the Company adopted a 17 year estimated  useful life
for  amortization of its patent and trademark rights in order to more accurately
reflect their useful life.  Prior to October 1, 2001, the Company was using a 10
year estimated  useful life. The adoption of the 17 year life had been accounted
for as a change in accounting estimate.

Patents  and  trademarks  are  stated  at cost  (primarily  legal  fees) and are
amortized  using the  straight  line  method  over the life of the  assets.  The
Company  reviews its patents and  trademark  rights  periodically  to  determine
whether  they have  continuing  value.  Such review  includes an analysis of the
patent and  trademark's  ultimate  revenue  and  profitability  potential  on an
undiscounted  cash flow basis to support  the  realizability  of its  respective
capitalized cost. Management's review addresses whether each patent continues to
fit into the Company's strategic business plans. During the years ended December
31, 2000,  2001 and 2002,  the Company  decided not to pursue the  technology in
certain countries for strategic reasons and recorded charges of $32,000, $38,000
and $5,000,  respectively.  Amortization  expense  was  $324,000,  $359,000  and
$201,000 in 2000, 2001 and 2002,  respectively.  The accumulated amortization as
of December 31, 2001 and 2002 is $2,096,000 and $1,996,000, respectively.

(f) Revenue

Revenue from the sale of  Ampligen(R)  under cost  recovery  clinical  treatment
protocols  approved by the FDA is  recognized  when the treatment is provided to
the patient.

Under the terms of an  agreement  granting  the  licensee  marketing  rights for
Ampligen(R) for the treatment of myalgic/chronic  fatigue syndrome ("ME/CFS") in
Spain,  Portugal and Andorra  require the Company to provide the  licensee  with
technical,  scientific and  commercial  information.  The Company  fulfilled the
requirements  during the first quarter of 2002. The agreement  terms required no
additional performance on the part of the Company.

The  agreement  also  requires the licensee to pay of 1,000,000  Euros after FDA
approval of Ampligen(R) for the treatment of ME/CFS and a fee of 1,000,000 after
issuance in Spain of final marketing approval  authorization for Ampligen(R) for
the treatment of ME/CFS. See Note 6 for more detailed information.

Revenues for  non-refundable  license fees are recognized  under the Performance
Method-Expected  Revenue.  This method  considers  the total  amount of expected
revenue  during  the  performance  period,  but  limits  the  amount of  revenue
recognized  in a period to total  non-refundable  cash  received  to date.  This


                                      F-11


limitation is appropriate  because future  milestone  payments are contingent on
future events.

Upon  receipt,   the  upfront  non  -  refundable   payment  is  deferred.   The
non-refundable  upfront payment plus  non-refundable  payments  arising from the
achievement of defined milestones are recognized as revenue over the performance
period based on the lesser of (a) percentage of completion or (b) non-refundable
cash earned (including the upfront payment).

This method  requires  the  computation  of a ratio of cost  incurred to date to
total expected costs and then applies that ratio to total expected revenue.  The
amount  of  revenue  recognized  is  limited  to the total  non-refundable  cash
received to date.

The  percentage  of  expenses  incurred  to date to total  expected  expenses in
connection with the research and development  project,  exceed the percentage of
license  fees  received  compared  to total  license  fees to be earned  per the
agreement. Therefore the amount of revenue recognized by the Company was limited
to the total non-refundable cash received to date of approximately $563,000.

During the periods ending  December 31, 2000,  2001 and 2002 the Company did not
receive any grant monies from local, state and or Federal Agencies.

(g) Net Loss Per Share

Basic and  diluted  net loss per share is computed  using the  weighted  average
number of shares of common  stock  outstanding  during  the  period.  Equivalent
common  shares,  consisting of stock  options and warrants,  are excluded from a
calculation of diluted net loss per share since their effect is antidilutive.

(h) Accounting for Income taxes

Deferred income tax assets and  liabilities are determined  based on differences
between  the  financial   statement  reporting  and  tax  bases  of  assets  and
Liabilities and are measured using the enacted tax rates and laws in effect when
the differences are expected to reverse.  The measurement of deferred income tax
assets is reduced, if necessary,  by a valuation allowance for any tax benefits,
which are not expected to be realized.  The effect on deferred income tax assets
and  liabilities  of a change in tax rates is recognized in the period that such
tax rate changes are enacted.

(i) Comprehensive (loss)

On January 1, 1998, the Company  adopted SFAS No. 130,  Reporting  Comprehensive
Income.  Statement of Financial  Accounting Standards (SFAS) No. 130 establishes
standards for reporting and presentation of the Company's  comprehensive  (loss)
and its components in a full set of financial  statements.  Comprehensive (loss)
consists of net loss and net  unrealized  gains  (losses) on  securities  and is
presented in the consolidated  statements of changes in stockholders' equity and
comprehensive (loss).

(j) Use of Estimates

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


                                      F-12


the reported amounts of revenues and expenses for the reporting  period.  Actual
results could differ from those estimates.

(k) Foreign currency translations

Assets  and  liabilities  of the  Company's  foreign  operations  are  generally
translated into U.S. dollars at current exchange rates as of balance sheet date.
Revenues and  expenses  are  translated  at average  exchange  rates during each
period.  Transaction gains and losses that arise from exchange rate fluctuations
are included in the results of operations as incurred. The resulting translation
adjustments are immaterial for all years presented.

(l) Recent Accounting Standard and Pronouncements:

In  January  2003,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Interpretation   No.  46,   "Consolidation   of  Variable   Interest   Entities"
("Interpretation No. 46"), that clarifies the application of Accounting Research
Bulletin No. 51,  Consolidated  Financial  Statements,  "to certain  entities in
which  equity  investors  do  not  have  the  characteristics  of a  controlling
financial  interest or do not have  sufficient  equity at risk for the entity to
finance its activities  without additional  subordinated  financial support from
other  parties.  Interpretation  No. 46 is applicable  immediately  for variable
interest entities created after January 31, 2003. For variable interest entities
created  to  January  31,  2003,  the  provision  of  Interpretation  No. 46 are
applicable  no later  than  July 1,  2003.  The  Company  does not  expect  this
Interpretation to have an effect on the consolidated financial statements.

In August  2001,  the FASB  issued  Statement  No.  143,  "Accounting  for Asset
Retirement Obligation" ("SFAS 143"), which provides the accounting  requirements
for retirement  obligation  associated with tangible long-lived assets. SFAS 143
requires  entities  to  record  the  fair  value of the  liability  for an asset
retirement obligation in the period in which it is incurred and is effective for
the Company's 2003 fiscal year. The adoption of SFAS 143 is not expected to have
a material impact on the Company's consolidated results of operations, financial
position or cash flows.

In  October  2001,  the FASB  issued  Statement  No.  144,  "Accounting  for the
Impairment or Disposal of Long-lived  Assets"  ("SFAS 144").  SFAS 144 addresses
financial  accounting and reporting for the impairment or disposal of long-lived
assets.  This statement  supersedes SFAS Statement No. 121,  "Accounting for the
Impairment of Long-Lived  Assets and for Long-Lived  Assets to Be Disposed Of, "
and the accounting and reporting provision of APB Opinion No. 30, "Reporting the
Results  of  Operations-Reporting  the  Effects  of  Disposal  of a Segment of a
Business,  and  Extraordinary,  Unusual and  Infrequently  Occurring  Events and
transactions.  "This new pronouncement also amends Accounting  Research Bulletin
(ARB) No. 51 "Consolidated Financial Statements,  "to eliminate the exception to
consolidation for a subsidiary for which control is likely to be temporary. SFAS
144  required  that one  accounting  model be used for  long-lived  assets to be
disposed of by sale, whether previously held and used or newly acquired and also
broadens the  presentation  of  discontinued  operation to include more disposal
transactions.  SFAS 144 is effective for fiscal years  beginning  after December
15, 2001 and interim periods within those fiscal years.  Adoption of SFAS 144 on
January 1, 2002, did not have impact on the Company's financial  position,  cash
flows or results of operation for the year ended December 31, 2002.

In June 2002, the FASB issued Statement No. 146, "Accounting for Cost Associated
with Exit or  Disposal  Activities"  ("SFAS  146"),  which  addresses  financial
accounting and reporting for costs associated with exit or disposal  activities,
and nullifies Emerging Task Force (EITF) Issue No. 94-3, "Liability  Recognition


                                      F-13


for Certain Employee  termination  Benefits and Other Costs to Exit and Activity
(including Certain Costs Incurred in a Restructuring)" which previously governed
the accounting treatment for restructuring activities. SFAS 146 applies to costs
associated  with an exit activity that does not involve an entity newly acquired
in a business  combination or with disposal  activity covered by SFAS 144. Those
costs include,  but are not limited to, the following:  (1) termination benefits
provide to current employees that are  involuntarily  terminated under the terms
of a  benefit  arrangement  that,  in  substance,  is  not  an  ongoing  benefit
arrangement or individual deferred-compensation  contract,(2) costs to terminate
a contract that is not a capital lease, and (3) costs to consolidated facilities
or relocated  employees.  SFAS 146 does not apply to costs  associated  with the
retirement  of long-lived  assets  covered by SFAS 143. SFAS 146 will be applied
prospectively  and is effective for exit or disposal  activities  after December
31, 2002.

In December 2002, the FASB issued Statement No. 148, "Accounting for Stock-Based
Compensation-Transition and Disclosure", and amendment of FASB Statement No. 123
("SFAS").  SFAS 148 amends FASB Statement No. 123,  Accounting  for  Stock-Based
Compensation,  to provide  alternative  method of transition  for an entity that
voluntarily  changes  to the fair  value  based of  accounting  for  stock-based
employee  compensation.  It  also  amends  the  disclosure  provisions  of  that
Statement  to require  prominent  disclosure  about the effects on reported  net
income of an entity's  accounting  policy  decisions with respect to stock-based
employee  compensation.  Finally,  this Statement amends  Accounting  Principles
Board ("APB") Opinion No. 28, Interim Financial  Reporting to require disclosure
about those effects in interim financial information.  SFAS 148 is effective for
financial  statements  for fiscal  years ending  after  December  15, 2002.  The
Company  will  continue  to  account  for  stock-based  compensation  using  the
intrinsic  value method of APB Opinion No. 25,  "Accounting  for Stock Issued to
Employees, "but has adopted the enhance disclosure requirements of SFAS 148 (See
Note 10).

(m) Research and Development Costs

Research and development related to both future and present products are charged
to operation as incurred.

(n) Stock Compensation

The  Company  applies  the  intrinsic  value  method  in  accordance  Accounting
Principles  Bulletin  (APB)  Opinion  No. 25,  "Accounting  for Stock  Issued to
Employees" in accounting  for  stock-based  compensation  of its employees  and,
accordingly,  no  compensation  cost  has been  recognized  for  stock  purchase
warrants  and  options   issued  to  employees.   Had  the  Company   determined
compensation  cost based on the fair value at the grant date for its stock-based
compensation of its employees in accordance with FASB 123 the Company's net loss
would have been increased to the pro forma amounts indicated below:

                                     (In Thousands except for per share data)

In 1999,  the Company  granted  275,000  warrants to employees in recognition of
services  performed  and services to be  performed.  The fair value of the stock
purchase   warrants   granted  during  1999  was  also   determined   using  the
Black-Scholes  option  pricing  model  with  a  rate  of  5.18%,  volatility  of
135.4%-294.31%,  and expected  lives of 2 years.  These warrants are included in
the  2,633,000  non-public  warrants  outstanding  as of  December  31,  2000 as
described in footnote 5 (ii). There were no warrants granted to employees during
2000. During 2001 the Company granted 406,650 warrants to employees. The Company
granted to  employees  8,000  options in 2000 and  94,000  options in 2001.  See
footnote 5(i). The fair value of stock options and warrants  granted during 2001
was  determined  using Black Scholes  Option Pricing Model with a rate of 4.23%,
volatility of 69.7% to 74.9% and expected life of three years. In 2002 1,622,000
warrants  were issued to  employees in  recognition  of services  performed  and
services to be performed. The fair value of the warrants granted during 2002 was
determined  using  Black  Scholes  Option  Pricing  model  with a rate of 5.23%,
volatility of 63.17%, and expected life of 2.5 and 4 years. The weighted average
fair value of those options and warrants granted during the years ended December
31, 2002, 2001 and 2000, were estimated as $0.62, $1.57 and $1.09,respectively.

For stock warrants granted to non-employees,  the Company measures fair value of
the equity instruments  utilizing the Black-Scholes method if that value is more
reliably  measurable  than  the  fair  value  of the  consideration  or  service
received. The Company amortizes such cost over the related period of service.

The exercise  price of all stock  warrants  granted was equal to the fair market
value of the  underlying  common  stock as  defined by APB 25 on the date of the
grant.

(c) New Equity Financing


                                      F-16


On March 20, 2002 our European  Subsidiary  Hemispherx  Biopharma  Europe,  S.A.
("Hemispherx,  S.A.")  entered  into a Sales  and  Distribution  agreement  with
Laboratorios  del Dr.  Esteve  S.A.  ("Esteve").  Pursuant  to the  terms of the
Agreement, Esteve was granted the exclusive right to market Ampligen(R) in Spain
Portugal and Andorra for the treatment of Myalgic  Encephalitis/Chronic  Fatigue
Syndrome  ("ME/CFS").  In addition to other terms and other projected  payments,
Esteve paid an initial and non  refundable  fee of 625,000 Euros  (approximately
$563,000) to Hemispherx  S.A. on April 24, 2002 as the first part of a series of
milestone based payments.

During March 2002,  Hemispherx  Biopharma  Europe,  S.A.  (Hemispherx  S.A.) was
authorized  to issue up to 22,000,000  Euros of seven  percent (7%)  convertible
preferred  securities.  Such securities will be guaranteed by the parent company
and will be  converted  into a  specified  number of shares of  Hemispherx  S.A.
pursuant to the securities  agreement.  Conversion is to occur on the earlier of
an initial  public  offering of Hemispherx  S.A. on a European stock exchange or
September 30, 2003.

Esteve  purchased   1,000,000  Euros  of  Hemispherx   Biopharma  Europe  S.A.'s
convertible  preferred  equity  certificates  on May 23, 2002.  During 2002, the
terms and conditions of these  securities  were changed so that these  preferred
equity  certificates  will be  converted  into the  common  stock of  Hemispherx
Biopharma,  Inc.  (HEB) in the event that a  European  IPO is not  completed  by
September  30,  2003.  The  conversion  rate is to be 300  shares of  Hemispherx
Biopharma,  Inc.'s  common  shares  for each 1,000  Euro  convertible  preferred
certificate. As a result the Company recorded approximately $946,000 as minority
interest in subsidiary on its balance sheet.

On  December  18,  2002,  we  proposed  that Esteve  convert  their  convertible
preferred equity certificates into Hemispherx common stock pursuant to the terms
of the agreement and all unpaid dividends at the market price on that conversion
date. On January 9, 2003, Esteve accepted our proposal. We are in the process of
registering these shares for public sale.

On March 13, 2003, we issued  347,445 shares of our common stock to Provesan SA,
an affiliate of Esteve S.A.,  in exchange  for  1,000,000  Euros of  convertible
preferred  equity  certificates  and any  unpaid  dividends.  As a result of the
exchange,  minority and subsidiary was transfer to stockholders'  equity on such
date.

The  contingent  conversion  price  was more than the then  market  value of the
parent  company's  or  subsidiaries'  common  stock  at each of that  respective
measurement dates. As a result and in accordance with Emerging Issues Task Force
(EITF) No. 00-27  "Application  of Issue No. 98-5  (Accounting  for  Convertible
Securities  with  Beneficial  Conversion  Features  or  Contingently  Adjustable
Conversion  Ratios) to Certain  Convertible  Instruments",  the  Company did not
ascribe any value to any contingent conversion feature.

(e) Stock Repurchase

On February 19, 1999, the Board of Directors  authorized the repurchase of up to
200,000 shares of the Company's common stock on the open market.  On February 8,
2000, the Board authorized the repurchase of another 200,000 shares.

The  Company's  repurchases  of shares of common stock are recorded as "Treasury
Stock" and result in a reduction of "Stockholders' equity." When treasury shares
are reissued,  the Company uses a first-in,  first-out  method and the excess of
repurchase cost over  reissuance  price is treated as a reduction of "Additional
paid-in capital."

(f) Rights offering

On November 19, 2002, the Board of Directors of Hemispherx Biopharma,  Inc. (the
"Company")  declared a dividend  distribution of one Right for each  outstanding
share of Common  Stock to  stockholders  of record at the close of  business  on
November 29, 2002 (the "Record Date"). Each Right entitles the registered holder
to purchase from the Company a unit consisting of one  one-hundredth  of a share
(a "Unit") of Series A Junior Participating  Preferred Stock, par value $.01 per
share (the "Series A Preferred  Stock") at a Purchase  Price of $30.00 per Unit,
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights Agreement (the "Rights  Agreement") between the Company and Continental
Stock Transfer & Trust Company, as Rights Agent.

 Initially,   the  Rights  are  attached  to  all  Common   Stock   certificates
representing  shares then outstanding,  and no separate Rights Certificates will
be distributed. Subject to certain exceptions specified in the Rights Agreement,
the Rights will  separate  from the Common  Stock and a  Distribution  Date will
occur upon the  earlier of (i) 10 days  following a public  announcement  that a
person or group of affiliated or associated persons (an "Acquiring  Person") has
acquired  beneficial  ownership  of 15% or more (or 20% or more for  William  A.
Carter,  M.D.) of the outstanding shares of Common Stock (the "Stock Acquisition
Date"), other than as a result of repurchases of stock by the Company or certain
inadvertent  actions by institutional  or certain other  stockholders or (ii) 10
business  days (or such later date as the Board shall  determine)  following the
commencement  of a tender offer or exchange  offer that would result in a person
or group  becoming an Acquiring  Person.  Until the  Distribution  Date, (i) the
Rights  will  be  evidenced  by  the  Common  Stock  certificates  and  will  be
transferred with and only with such Common Stock  certificates,  (ii) new Common
Stock  certificates  issued  after  the  Record  Date will  contain  a  notation
incorporating  the Rights  Agreement by reference  and (iii) the  surrender  for
transfer of any certificates  for Common Stock  outstanding will also constitute
the transfer of the Rights  associated with the Common Stock represented by such
certificate. Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the  occurrence of a Triggering  Event (as defined below) that,
upon any exercise of Rights,  a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

In August 1988, the Company entered into a pharmaceutical  use license agreement
with Temple University (the Temple Agreement).  In July, 1994, Temple terminated
the Temple Agreement. In November 1994, the Company filed suit against Temple in
the Superior Court of the State of Delaware seeking a declaratory  judgment that
the agreement was unlawfully terminated by Temple and therefore remained in full
force and effect.  Temple filed a separate  suit  against the Company  seeking a
declaratory   judgment  that  its  agreement   with  the  Company  was  properly
terminated. These legal actions have now been settled. Under the settlement, the
parties have entered into a new pharmaceutical use license agreement (New Temple
Agreement)  that is  equivalent  in duration and scope to the previous  license.
Under the terms of the New  Temple  Agreement,  Temple  granted  the  Company an
exclusive  world-wide  license for the term of the agreement for the  commercial
sale of Oragen  products  using patents and related  technology  held by Temple,
which  license is exclusive  except to the extent  Temple is required to grant a
license to any governmental agency or non-profit  organization as a condition of
funding for research and  development of the patents and technology  licensed to
the Company.

the Company from any joint venture or corporate partnering agreement.

In October 1994, the Company  entered into a licensing  agreement with Bioclones
(Propriety)  Limited  (SAB/Bioclones)  with respect to co-development of various
RNA drugs,  including  Ampligen(R),  for a period  ending  three  years from the

SAB/Bioclones with an exclusive  manufacturing and marketing license for certain
southern  hemisphere  countries  (including  certain countries in South America,
Africa and  Australia as well as the United  Kingdom and Ireland  (the  licensed

produces raw material components of Ampligen(R) and (c) royalties of 6% to 8% of
net sales of the licensed products in the licensed territories as defined, after
the first $50 million of sales.  SAB/Bioclones  will be granted a right of first
refusal to manufacture and supply to the Company licensed  products for not less
than one third of its world-wide sales of Ampligen(R),  excluding  SAB/Bioclones
related sales. In addition,  SAB/Bioclones  will have the right of first refusal
for oral  vaccines in the  licensed  territory.  In 2000,  the  Company  paid to
Ribotech a total of $500,000 for the current and future  purchases  and delivery

(11) Income Taxes

As of December 31, 2002,  the Company has  approximately  $66,000,000 of federal
net  operating  loss  carryforwards  (expiring in the years 2004  through  2022)
available  to  offset  future  federal  taxable  income.  The  Company  also has
approximately $15,000,000 of state net operating loss carryforwards (expiring in
the years 2003 through 2007)  available to offset  future state taxable  income.
The utilization of certain state net operating loss carryforwards may be subject
to annual limitations.

Under  the Tax  Reform  Act of 1986,  the  utilization  of a  corporation's  net
operating loss  carryforward  is limited  following a greater than 50% change in
ownership.  Due to the  Company's  prior and current  equity  transactions,  the
Company's  net  operating  loss  carryforwards  may  be  subject  to  an  annual
limitation  generally  determined by multiplying the value of the Company on the
date of the  ownership  change by the federal  long-term  tax exempt  rate.  Any
unused annual  limitation may be carried forward to future years for the balance
of the net operating loss carryforward period.

Deferred  income  taxes  reflect  the net tax effects of  temporary  differences
between  carrying  amounts of assets and  liabilities  for  financial  reporting
purposes and the carrying amounts used for income tax purposes. In assessing the
realizability of deferred tax assets,  management  considers  whether it is more
likely than not that some  portion or all of the deferred tax assets will not be
realized.  The  realization  of  deferred  tax  assets  is  dependent  upon  the
generation  of future  taxable  income  during the  periods  in which  temporary
differences representing net future deductible amounts become deductible. Due to
the uncertainty of the Company's  ability to realize the benefit of the deferred
tax asset, the deferred tax assets are fully offset by a valuation  allowance at
December 31, 2001 and 2002.

The  components  of the net  deferred  tax asset of  December  31, 2001 and 2002
consists of the following:

(12) Contingencies

On September  30,  1998,  we filed a  multi-count  complaint  against  Manuel P.
Asensio,  Asensio & Company,  Inc.  ("Asensio").  The action  included claims of
defamation,  disparagement,  tortuous interference with existing and prospective
business  relations  and  conspiracy,  arising  out of the  Asensio's  false and
defamatory  statements.  The complaint  further alleged that Asensio defamed and
disparaged  us  in  furtherance  of  a  manipulative,   deceptive  and  unlawful
short-selling  scheme in August and September,  1998. In 1999,  Asensio filed an
answer and  counterclaim  alleging  that in  response to  Asensio's  strong sell
recommendation  and other press releases,  we made defamatory  statements  about
Asensio. We denied the material  allegations of the counterclaim.  In July 2000,
following dismissal in federal court for lack of subject matter jurisdiction, we
transferred  the action to the  Pennsylvania  State  Court.  In March 2001,  the
defendants  responded  to the  complaints  as amended and a trial  commenced  on
January 30, 2002. A jury verdict  disallowed  the claims  against the defendants
for defamation and  disparagement and the court granted us a directed verdict on
the  counterclaim.  On July 2, 2002 the Court entered an order granting us a new
trial against  Asensio for defamation  and  disparagement.  Thereafter,  Asensio
appealed the granting of a new trial. This appeal is now pending in the Superior
Court of Pennsylvania.

In June 2002, a former  ME/CFS  clinical  trial  patient and her husband filed a
claim in the Superior Court of New Jersey,  Middlesex County, against us, one of
our clinical trial  investigators and others alleging that she was harmed in the
ME/CFS  clinical trial as a result of negligence  and breach of  warranties.  We
believe the claim is without  merit and we are  defending  the claim  against us
through our product liability insurance carrier.

In June 2002, a former ME/CFS clinical trial patient in Belgium filed a claim in
Belgium, against Hemispherx Biopharma Europe, NV/SA, our Belgian subsidiary, and
one of our  clinical  trial  investigators  alleging  that she was harmed in the
Belgium  ME/CFS  clinical  trial  as  a  result  of  negligence  and  breach  of
warranties. We believe the claim is without merit and we are defending the claim
against us through our product liability insurance carrier.

In July 2002, we filed suit in the United States  District Court for the Eastern
District of  Pennsylvania  against our insurance  company seeking (1) a judicial
order  declaring our rights and the  obligations of our insurance  carrier under
the insurance  policy our insurance  carrier sold to us (2) monetary  damage for
breach of contract  resulting from our insurance carrier refusal to fully defend
us in connection with the Asensio  litigation (3) monetary damages to compensate
us for our insurance  carrier breach of its fiduciary duty faith and dealing and
(4) monetary  damages,  interest,  cost, and attorneys fees to compensate us for
violation of the  Pennsylvania  Bad Faith Statute.  On March 31, 2003 we settled
our  outstanding  claim with our insurance  carrier for  $1,500,000  relating to
reimbursement of expenses in connection with our Asensio law suits. We expect to
realize  approximately  $1,050,000  of this  amount  after  payment of  expenses
related to the  settlement.  Such amount was recorded  during the fourth quarter
2002 as a reduction in General and  Administrative  expenses in our statement of
operations.

In March 2003,  one of our former law firms  filed a  complaint  in the Court of
Common Pleas of Philadelphia County against us for alleged legal fees in the sum
of $65,051. We believe the claim is without merit and are defending the matter.

(13) Related Party Transactions

(14) Concentrations of credit risk

Financial  instruments,  which potentially subject the Company to concentrations
of credit risk,  consist  principally  of cash. The Company places its cash with
high-quality financial  institutions.  At times, such amount may be in excess of
Federal Deposit Insurance Corporation insurance limits of $100,000.

(16)  Debenture Financing

On March 12, 2003, We issued an aggregate of  $5,426,000 in principal  amount of
6% Senior  Convertible  Debentures  due  January 31,  2005 and an  aggregate  of
743,288  Warrants  to  two  investors  in  a  private  placement  for  aggregate
anticipated  gross  proceeds  of  $4,650,000.  Pursuant  to  the  terms  of  the
Debentures, $1,550,000 of the proceeds from the sale of the Debentures have been
held back and will be released to us if, and only if, we acquire ISI's  facility
with in a set  timeframe.  The  Debentures  mature on January  31, 2005 and bear
interest at 6% per annum,  payable quarterly in cash or, subject to satisfaction
of certain  conditions,  common stock.  Any shares of common stock issued to the
investors as payment of interest  shall be valued at 95% of the average  closing
price of the common stock during the five  consecutive  business  days ending on
the third business day  immediately  preceding the applicable  interest  payment
date. Pursuant to the terms and conditions of the Senior Convertible Debentures,
we have pledged all of our assets as  collateral  and are subject to comply with
certain financial and negative  covenants,  which include but are not limited to
the repayment of principal balances upon achieving certain revenue milestone.


                                      F-28


The  Debentures  are  convertible  at the  option of the  investors  at any time
through January 31, 2005 into shares of our common stock.  The conversion  price
under the  Debentures  is fixed at $1.46 per share,  subject to  adjustment  for
anti-dilution  protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in effect.

The investors  also  received  Warrants to acquire at any time through March 12,
2008 an  aggregate  of  743,288  shares of common  stock at a price of $1.68 per
share.  On March 12, 2004,  the exercise price of the Warrants will reset to the
lesser of the  exercise  price then in effect or a price equal to the average of
the daily price of the common  stock  between  March 13, 2003 and March 11, 2004
(but in no event less than $1.176 per share).  The exercise price (and the reset
price)  under  the  Warrants  also  is  subject  to  similar   adjustments   for
anti-dilution protection.

We entered into a registration rights agreement with the investors in connection
with the issuance of the Debentures and the Warrants.  The  registration  rights
agreement  requires  that we register the shares of common stock  issuable  upon
conversion of the  Debentures,  as interest  shares under the Debenture and upon
exercise  of the  Warrants.  In  accordance  with  this  agreement,  we  filed a
registration  statement on form S-3 with the Securities and Exchange Commission.
If the registration  statement is not declared  effective within the time period
required by the  agreement  or,  after it is declared  effective  and subject to
certain exceptions, sales of all shares required to be registered thereon cannot
be made pursuant thereto, then we will be required to pay to the investors their
pro rata  share of $3,635  for each day any of the above  conditions  exist with
respect to this registration statement.
