ITEM 1.  Business

General
In the course of almost three decades Hemsipherx Biopharma, Inc.
(the Company) has established a strong platform of laboratory, pre-clinical
and clinical data for the purpose of successfully
commercializing its portfolio of nucleic acid drugs for the
treatment of viral diseases, immune system dysfunction and certain
cancers.  The Company's proprietary drug technology utilizes
specifically configured ribonucleic acid (RNA).  The Company's lead
double-stranded RNA drug product, trademarked Ampligen , which is
administered intravenously, is in human clinical development for
various therapeutic indications.  Ampligen  is presently undergoing
Phase III clinical trials in the United States and Europe for the
treatment of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
("ME/CFS").  Based on the results of pre-clinical studies and
clinical trials, Hemispherx believes that Ampligen  may have broad-spectrum
anti-viral and anti-cancer activities.  Hemispherx business
strategy is designed around seeking the required regulatory
approvals which will allow the progressive introduction of Ampligen
and other compounds based on similar mechanisms of action.

The Company was incorporated in Maryland in 1966 under the name HEM
Research, Inc., and originally served as a supplier of research
support products.  The Company's business was redirected in the
early 1980's to the development of nucleic acid pharmaceutical
technology and the commercialization of RNA drugs.  The Company was
reincorporated in Delaware and changed its name to HEM
Pharmaceuticals Corp., in 1991 and to Hemispherx, BioPharma, Inc.,
in June 1995.  The Company has three domestic subsidiaries BioPro
Corp., BioAegean Corp., and Core BioTech Corp., all of which are
incorporated in Delaware.  Our foreign subsidiary, Hemispherx
BioPharm-Europe, was established in Belgium in 1998.  The Company's
principal executive offices are located at One Penn Center, 1617 JFK
Boulevard, Philadelphia, Pennsylvania 19103, and its telephone
number is (215) 988-0080.

The Company holds more than 300 patents worldwide, with over 80
additional patent applications pending to provide further
proprietary protection in various international markets.  The U.S.
FDA has granted the Company "Orphan Drug Status" for its nucleic
acid-derived therapeutics for CFS/ME, HIV and renal cell carcinoma
and malignant melanoma.  Orphan Drug Status grants protection
against competition for a period of seven years following FDA
approval, as well as certain tax incentives.  While the  Company's
clinical advancements to date exceed the vast majority of
biotechnology companies (in a universe of approximately 1,300
companies) no assurance can be given that any of these

<PAGE>
<PAGE> 3
programs will lead inevitably to major commercial success and/or
further regulatory advances.

The Company outsources significant components of its research and
development, manufacturing, marketing and distribution while
maintaining tight control over the entire process through 'system
management'.  A portion of the Company's research and development
is provided under contract with scientists and technicians who are
not employed by the Company but who are employed by academic
institutions.  The Company also draws upon the expertise of outside,
part-time consultants from time to time.

The efficacy and safety of Ampligen is currently being examined for
the treatment of ME/CFS in a confirmatory Phase III multicenter,
placebo-controlled, randomized, double-blind clinical trial in the
United States.  The Company plans to enroll up to 230 ME/CFS
patients in this clinical trial.  Other ME/CFS clinical efforts
include the Cost Recovery Treatment Programs underway in the United
States, Canada, Belgium and Austria.  In late 1999, the Company
announced the roll-out of a new pan-European, expanded access cost
recovery treatment program for severely ill ME/CFS patients.  This
program was implemented in response to growing requests from
physicians and patients.  The Company will work with certain
physicians and medical centers seeking regulatory approval to
administer Ampligen to severely ill patients.

In addition to the ME/CFS clinical effort, the Company is ramping
up its focus on HIV and the complications of AIDS.  A potential
effect of Ampligen may lie in treating HIV patients, especially
those with a multidrug resistant virus.  The Company is developing
clinical programs with Anderson Clinical Research designed to
address the growing problem of multi-drug resistance found in
battling the AIDS epidemic in the United States and the rest of the
world.  Anderson Clinical Research is based in Pittsburgh and is a
renowned clinical research organization that specializes in
sponsoring clinical trials in AIDS and related immunological
disorders.  The clinical programs being developed are a direct
outgrowth of data obtained in comprehensive ex vivo testing
sponsored by the Company through a non-restricted research grant at
the University of California at Irvine as well as a research
contract at the California Institute of Molecular Medicine, based
on leadership provided by an expert in HIV from Vanderbilt
University School of Medicine in Nashville.  The focus of this
effort is to evaluate the potential of RNA technology to be used in
conjunction with approved antiviral "cocktails" to overcome the
emergence of multi-drug resistant HIV strains.  Because of the
complexity of existing multiday regimens for treating HIV, the
Company may elect initially to treat individual patients brought to
its attention (on an emergency basis) by specific physicians rather
than to implement a standard protocol

<PAGE>
<PAGE> 4
involving a group of patients authorized by regulatory authorities.
Other programs will be established to determine the potential of RNA
technology in treating other chronic viruses including hepatitis
B and C.

The development of the Company's products has required and will
continue to require the commitment of substantial resources to
complete the time-consuming research, preclinical development, and
clinical trials necessary to bring pharmaceutical products to market
and establish commercial production and marketing capabilities.
Accordingly, the Company may need to raise additional funds through
additional equity or debt financing, collaborative arrangements with
corporate partners, off balance sheet financing or from other
sources in order to complete the necessary clinical trials and the
regulatory approval processes and begin commercializing its
products.  There can be no assurances that the Company will be
successful in obtaining regulatory approval.

ME/CFS
Chronic Fatigue Syndrome (ME/CFS), also known as Chronic Fatigue and
Immune Dysfunctional Syndrome (CFIDS) or, in Europe, Myalgic
Encephalomyelitis (ME) is a debilitating disease that has been
difficult to diagnose and for which, at present, there is no cure.
People suffering from this illness experience amongst other, a
constant tiredness, recurring dull headaches, joint and muscle
aches, a feeling of feverishness and chills without fever,
depression, difficulty in concentrating on tasks, and tender lymph
glands.  Central nervous symptoms include memory loss and dementia.

In October, 1998, the Company initiated, with the U.S. Food and Drug
Administration ("FDA") authorization, a confirmatory, double-blind,
placebo-controlled clinical study with Poly I:Poly C12U (Ampligen )
in patients with severely debilitating Myalgic
Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS).  The objective
of this confirmatory Phase III clinical study is to evaluate the
safety and efficacy of Ampligen as a treatment for ME/CFS.

As of February 29, 2000, ten clinical investigators, at various
medical facilities throughout the U.S., were recruiting patients for
this clinical study.  These clinical investigators have recruited
and enrolled more than 60 per cent of the required 230 patients
needed to complete this clinical study.  The Company expects to
engage the services of several additional clinical investigators
to assist in the recruitment of the additional patients needed to
participate in this study.

In March, 1999 the U.S. Food and Drug Administration authorized the
Company to expand it's ME/CFS Cost Recovery Treatment Program to
provide therapy to 100

<PAGE>
<PAGE> 5
active patients.  Under this clinical
program, the enrolled patients may pay the Company for the cost of
the Ampligen doses infused.  This usually totals approximately
$7,200 for a 24 week treatment program.  Approximately 82 per cent
of the patients who enter the program opt to extend their therapy
by an additional 24 weeks with the consent of their health care
providers.  In the twelve months ending December 31, 1999, the
Company has received $391,681 in reimbursement for Ampligen used
under this plan from the U.S. component of ME/CFS treatment
protocols.  Overall income from these programs was $678,248 for the
twelve month period, which includes Europe and Canada.

The Company has established strategic relationships with three other
companies to provide clinical/pharmacy support services and to
facilitate the conduct of its clinical studies according to Good
Clinical Practice ("GCP") standards.  Two entities, Gentiva Health
Services (formerly Olsten Health Services) and Clinical Studies
Management Group provide clinical monitors who verify the accuracy
of the data collected by the clinical investigators for ultimate
analysis by the Company.  Additionally, a third entity consisting
primarily of exercise physiologists, WorkWell, a company comprised
of professional exercise physiologists, provides exercise
physiologists to conduct standardized exercise tolerance and oxygen
consumption tests at the various clinical facilities across the
United States.  The Company believes that it has in place various
corporate relationships and programs to insure the quality of data
collection to a high international regulatory standard.

The ME/CFS Cost Recovery Treatment Program in Belgium was started
in 1994 with the approval of the Belgium Regulatory authorities.
Since its inception, over 120 patients have enrolled in this
program.  Clinical data being collected in the treatment of these
ME/CFS patients will be of support within the European Medical
Evaluation Agency ("EMEA") Drug Approval Application and in other
regulatory jurisdictions.  This program is being expanded to several
other affiliated hospitals in the Brussels area and clinical experts
in this disease category have been identified in other European
countries to establish similar clinical research/treatment centers
for ME/CFS.  A similar program in Austria is undergoing expansion.
Recently, the physicians involved in this program were brought
together for a three day conference to share clinical results and
to plan further clinical collaborations in the U.S., Canada and
Europe.

ME/CFS was also given official recognition by the U.S. Social
Security Administration, rendering ME/CFS patient potentially
eligible for disability benefits and heightening awareness of this
debilitating disease in the medical community.  A scientific article
by independent academicians on the accurate laboratory diagnosis of
CFS was published in February, 2000 in a peer-reviewed

<PAGE>
<PAGE> 6
journal.  The U.S. Centers for Disease Control (Atlanta, GA)
reconfirmed its research commitment to CFS following an audit
by the U.S. Government Accounting Office (GAO) which was announced
approximately July 28, 1999.

The Company has entered into a research collaboration with RED
Laboratories, N.V. (`RED'), a Belgium company dedicated to the
development and commercialization of ME/CFS diagnostics.  RED
reported significant progress in developing a diagnostic test
(designated REDD) for ME/CFS.  The testing platform is based on the
measurement of an abnormal form of protein RNase L, an antiviral
enzyme found in the white blood cells of CFS/ME patients.  This
abnormal enzyme was first discovered in 1996 by researchers at
Temple University who have been actively collaborated with The
Company's scientists for a number of years.  It is believed that the
new RED diagnostic test may identify up to 80-90 per cent of CFS/ME
patients by recognizing a defect caused by the disease.  The test
may enable doctors to more quickly identify CFS/ME patients and
start immediate treatment to help facilitate a positive medical
outcome for the patient as well as a cost-effective solution for the
health-care provider.  Hemispherx has independently filed patents
on certain aspects of the diagnostic technology in the U.S. and
abroad.

Also, preclinical collaborative studies are being conducted on Gulf
War Syndrome.  Patients with this illness appear to have certain
symptoms similar to patients with ME/CFS.

HIV

While the Company is currently concentrating on the use of Ampligen
as a treatment for ME/CFS, recent developments in the healthcare
community with respect to future care and treatment of HIV patients
is now prompting the Company to reexamine and consider the
acceleration of developing RNA technologies for the treatment of
patients with HIV.

Today, patients infected with HIV receive a number of different
combinations of anti-retroviral compounds (so called "Cocktails")
that target the essential viral enzymes, including reverse
transcriptase and protease.  However, it appears that after some
period of time, the HIV virus may become resistant to these
antiviral drugs and that drug resistance profile is a critical
obstacle to the long-term efficacy of present 'cocktail' therapies
for HIV.

Most recently, HIV strains which are resistant to essentially all
of the currently available anti-retroviral drugs are now being
increasingly reported in patients in the U.S. who have received
highly active anti-retroviral therapy,

<PAGE>
<PAGE> 7
termed "HAART."  Many HIV patients who receive HAART (including
a protease inhibitor) may encounter virologic failure within one year.
According to independent sources, of an estimated 100,000 new patients
in the U.S.A. initiating HAART last year, there were approximately
150,000 "treatment switches," evidencing significant problems with the
regimens.  Moreover, the presence of latently infected, resting
immune cells termed CD4+ T cells carrying replication-competent HIV
has been demonstrated in patients receiving HAART.

Ampligen  may have certain potential, as an adjunct to HAART to
restore certain functional components of the immune process which
becomes deficient in HIV disease.  Second, Ampligen may have
potential to mitigate the deterioration in CD4 count when patients
are failing HAART therapy. Third, Ampligen may have potential to
assist HAART therapy because of its apparent synergistic activity
with AZT and possibly other cocktail components (these studies are
underway). These presumptive benefits are being evaluated by the
Company in either ongoing ex vivo or in proposed in vivo clinical
programs.  The molecular basis of the putative drug synergism has
not yet been established at the clinical level and will require
clinical studies which have not been initiated.

In conjunction with AZT, Ampligen  infusion therapy was historically
well tolerated in the initial clinical tests, some of which has been
published in peer reviewed journals.  Thus, overall safety
assessments supported a reasonable safety profile of this drug
combination consisting of an antiretroviral agent (AZT) utilized in
conjunction with a specific dsRNA (Ampligen ).  Studies are now
being considered to combine Ampligen with other reverse
transcriptase inhibitors of HIV as well as protease inhibitors of
HIV.  Ex vivo tests are presently being conducted at various
academic and industrial laboratories around the U.S.A. via research
agreements and corporate partnerships recently initiated by the
Company.

The Company is working with Anderson Clinical Research to develop
immunologically based Clinical Programs that are designed to address
this growing problem of multi-drug resistance found in battling
AIDS.  These clinical programs are an outgrowth of comprehensive ex
vivo testing recently sponsored by the Company which examined the
relative antiviral strengths of fourteen FDA approved antivirals.
The results of these tests were presented in part at the IBT AIDS
meetings in Boston, MA (December, 1999) and will be presented in
full at the upcoming 13th Annual International Antiviral Conference
in Baltimore, MD in April 2000.  These studies were funded in part
by unrestricted grants from the Company.

Anderson Clinical Research is a recognized clinical research
organization that specializes in sponsoring clinical trials in AIDS
and related immunological disorders.  This experimental approach may
represent one of the first times that

<PAGE>
<PAGE> 8
immunomodulatory drugs are being overlaid in a systematic manner on
the approved antiviral "Cocktails" in an effort to overcome the growth
of emerging drug resistant HIV strains.  No assurance can be given that
the outcome of these clinical studies will be similar to the ex vivo
studies or dates upon which these studies will receive regulatory
authorization to commence.

Manufacturing

The Company outsources the manufacturing of Ampligen 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 materials used in the
production of Ampligen.  The Company acquires its raw materials from
Ribotech, Ltd., a subsidiary of Bioclones Proprietary, Ltd., and
Pharmacia Biotech, a former division of Pharmacia Upjohn which holds
a minority equity interest in the Company.  Bioclones Proprietary,
Ltd. is a strategic partner with the Company that operates Ribotech,
Ltd. in South Africa.  Two manufacturers in the United States are
utilized to process the raw materials and produce clinical grade
Ampligen.

Until recently, the Company has distributed Ampligen in the form of
a freeze-dried powder to be formulated by pharmacists at the site
of use.  The Company has perfected a production process to produce
ready to use liquid Ampligen in a dosage form which will mainly be
used upon commercial approval of Ampligen.  The Company has engaged
the services of Schering-Plough Products to mass produce ready-to-use
Ampligen doses.  Schering-Plough has completed several pilot
runs which meets all required product specifications.  Progressively
larger manufacturing runs are planned in the first half of 2000.
After appropriate quality assurance testing, the product from these
runs will be used for clinical purposes.

Bioclones (PTY) Ltd. has also successfully completed a series of
production runs for liquid Ampligen doses.  This was done at
Ribotech's facility in South Africa that has inspection approval by
both the Food and Drug Administration of the United States and the
Medicine Control Authority of the United Kingdom.  Bioclones (PTY)
Ltd. 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.  The licensing agreement
with Bioclones presently includes South Africa, South America,
Ireland, New Zealand and the United Kingdom.  Bioclones has recently
initiated limited clinical testing in Great Britain.

<PAGE> 9
European Operations

In 1998, the Company formed a wholly-owned European subsidiary
domiciled in Belgium under the name of Hemispherx Biopharma Europe.
This entity was created to facilitate the European ME/CFS Cost
Recovery Treatment programs as well as conduct ME/CFS clinical
trials in connection with eventually obtaining European approval by
the European Medical Evaluation Agency ("EMEA").

In response to growing requests from physicians and ME/CFS patients
in Europe, the Company is increasing its European Operations to
expand its cost recovery treatment programs into additional European
countries.  Presently, Ampligen is available to certain ME/CFS
patients in Belgium and Austria.

The Company plans to establish a network of clinical centers with
experience in evaluating ME/CFS patients.  These centers, termed
Fatigue Approved Clinical Treatment Centers (FACT), will be
developed as centers of medical excellence combining the state of
art diagnostic techniques, as well as, well-developed treatment
expertise in treating ME/CFS.  The Company believes that
establishment of FACT may assist in obtaining regulatory approval
for the Cost Recovery Treatment Program in the other European
countries.

In December, 1998, the Company filed an initial application with the
(EMEA) for authorization to use Ampligen in the treatment of ME/CFS
in the European Union.  The Company submitted extensive data and
analysis in support of the application.  The review process by EMEA
has produced ongoing dialogue.  The Company has sought an
acceleration of the overall process by requesting certain "special
circumstances" provisions which are being developed by the European
Parliament to accelerate drug availability for certain classes of
severe diseases without adequate treatment.  There are no assurances
that the EMEA will accept the "special circumstances" provision to
accelerate their review and approval and no assurances that
commercial approval will be granted.

Hemispherx Biopharma Europe is developing an organization and
infrastructure to expand access to Ampligen while under clinical
development.  Initial efforts include recruiting staff to establish
distribution and marketing processes with the immediate focus on
setting up Expanded Access Cost Recovery Treatment Programs of
ME/CFS patients in France, Italy, Spain and Germany.  If successful,
this program will allow ME/CFS patients in those countries to have
access to Ampligen prior to the completion of the full commercial
registration process.  During this time, the Company would also
realize enhanced revenues from its expanded access programs.  Also
this program will allow the Company to have a basic marketing and
distribution system in place.

<PAGE>
<PAGE> 10
The Company recently acquired 3 per cent ownership in a Belgium
company, R.E.D. Laboratories, which developed a diagnostic test
designed to detect ME/CFS in patients.  The R.E.D. diagnostic test
is in the process of being evaluated in the clinical setting.  The
significance of this development is that the test may facilitate the
identification of a subset of ME/CFS sufferers who may be treated
with Ampligen.  It is believed that introduction of such a test
might facilitate the regulatory approval process for the use of
Ampligen in treating ME/CFS, as well as identify suitable candidates
for therapy earlier in the disease process.  R.E.D. has indicated
it may publish the results of its testing as early as July 2000.

The Company recently presented a comprehensive clinical overview of
its ME/CFS treatment program at "Fatigue 2000", an international
research conference held in London.  The Company and its
collaborators have developed a report on the potential
pharmacoeconomics of using Ampligen to treat ME/CFS patients.  This
data will eventually be submitted to various regulatory and drug
reimbursement authorities in certain countries making up the
European Union.

In addition, progress was made towards the development of inventory
control and to expand quality assurance facilities in the European
Union.  The Company is seeking to identify and/or implement certain
quality control processes, packaging and storage capacity as well
as identifying new distribution channels in Europe.

Pharmacoeconomics

EPI-Q, an independent company based in Indianapolis, IN, conducts
in depth pharmacoeconomic studies, released the results of their
evaluation of the potential economic benefits of Ampligen therapy
versus existing conventional treatment.  Their analysis found a
decrease in the number of doses of other medications used and
inpatient hospital treatment days when Ampligen was used in the
treatment of severe ME/CFS patients.  Their results were presented
at the Second World Congress on CFS/ME held in Brussels on September
9-12, 1999.

The results of this analysis suggests a significant decrease in the
number of doses of so called concomitant medications (required to
alleviate ME/CFS symptoms) between the treatment and control groups.
The patients receiving Ampligen, the Company's lead compound, also
demonstrated the need for fewer inpatient hospital treatment days
during the 24 weeks study period.  According to EPI-Q this effect
would translate into an approximate annualized decrease in hospital
charges alone of $5,806.  According to the EPI-Q study, the mean
annualized healthcare charges for the treatment group were $2,097
versus $8,606 for the placebo group.  No assurances can be given
that the results of this

<PAGE>
<PAGE> 11
pharmacoeconomic study, or any corollary results will result in
reimbursement by healthcare insurance
carriers.

An object of this study was to document the potential
pharmacoeconomic impact of using Ampligen in the treatment of
ME/CFS.  This disease frequently leads to persistent disability and
requires frequent intervention by healthcare groups, as well as long
term outpatient treatment of pain and central nervous system
symptoms.  Currently, the care of these patients leads to a
significant financial burden to both patients and payers as well as
society in general.  Studies by various other health authorities
have placed the potential overall burden of untreated ME/CFS on
society to be in the billions of dollars.

Financing

The development of the Company's products has required and will
continue to 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 and to establish commercial-sale production and marketing
capabilities.  During the Company's last three fiscal years, the
Company has spent approximately $12,475,031 in research and
development, of which $4,737,058 was expended in the year ended
December 31, 1999.

At the present time, the Company is funding its European subsidiary
from the Company's cash flows.  The funding needs of the European
subsidiary could be substantial over the next few years.  To address
the funds needed, the Company has engaged an investment banking firm
in Europe to evaluate the prospect of privately placing 20% of the
European subsidiary's equity with outside investors to fund European
operations.  This method of acquiring additional funds may not be
needed as investors holding the Class A Redeemable Warrants
(AMEX:HEBws) are exercising their holdings thereby improving the
Company's cash flow and cash position.

Hemispherx Biopharma Europe has an exclusive license on all the
technology and support from the Company concerning Ampligen  for the
use of ME/CFS and other applications for all countries of the
European Union (excluding the UK wherein Bioclones has a marketing
license) and Norway, Switzerland, Hungry, Poland, Czechoslovakia,
Russia, Ukraine, Romania, Bulgaria, Slovakia, Turkey, Iceland and
Liechtenstein.  There is also an agreement between Hemispherx U.S.
and Hemispherx Europe to ensure that the commercialization of future
technologies can take place under conditions which would properly
incentivize Hemispherx Europe.

<PAGE>
<PAGE> 12
As of December 31, 1999, the Company had $8,549,389 in cash and
short term investments.  Based on its current operating plan, the
Company expects that anticipated receipt of revenues from the cost
recovery treatment protocols and interest income on unused funds
will be sufficient to meet the Company's operating requirements well
into 2001.  In addition, the Company may receive proceeds in the
form of equity from the exercise of shareholder warrants.  In 1999,
the Company received $1,923,473 in equity from shareholders
exercising warrants.  The amount of additional funding required, if
any, will depend on the timing of regulatory approval and
commercialization of Ampligen.

Accordingly, the Company may raise substantial additional funds
through additional equity or debt financing, collaborative
arrangements with corporate partners, off balance sheet financing
or from other sources in order to complete the necessary clinical
trials and the regulatory approval processes and begin
commercializing its products.  If adequate funds are not available
from operations and if the Company is not able to secure additional
sources of financing on acceptable terms, the Company's business
would be materially adversely affected.

Research and Development/Collaborative Agreements

The Company has formed a strategic alliance with Bioclones
Proprietary for manufacturing and international market development
in Africa, Australia, New Zealand, Tasmania, the United Kingdom,
Ireland and certain countries in South Africa, of Ampligen  and
Oragen .  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.

Bioclones has been given the first right to refusal, subject to
pricing, to manufacture at least one-third of the worldwide sales
requirement of Ampligen and other nucleic acid-derived drugs.
Pursuant to this arrangement, the Company received access to
worldwide markets and commercial-scale manufacturing resources, as
well as a $3 million cash payment from Bioclones, a 24.9% ownership
in a company set up by Bioclones to develop and manufacture RNA
drugs, and royalties of 8% on Bioclones nucleic acid-derived drug
sales in the licensed territories.  The Company regularly conducts
quality control audits of the facility.

In the United States, the Company has 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 to patients suffering from ME/CFS, both in the
cost recovery treatment program as well as the

home infusion market upon commercialization.  Gentiva is one of the
nation's largest home health care companies with over 600 offices and
several hundred thousand employees nationwide.  Pursuant to the
agreement, Gentiva will be responsible for marketing, distribution,
billing and collecting.  Through this arrangement, Hemispherx mitigates
the necessity of incurring significant up-front marketing and
distribution costs.  There can be no assurances that this alliance
will develop a significant commercial position in any of its
targeted chronic disease markets.

The Company acquired a series of patents on Oragen , potentially an
oral broad spectrum antiviral, through a licensing agreement with
Temple University.  The Company was granted an exclusive worldwide
license from Temple for the Oragen  products.  Pursuant to the
arrangement, the Company is obligated to pay royalties of 2% to 4%
on sales of Oragen , depending on how much technological assistance
is required of Temple.  The Company currently pays minimum royalties
of $30,000 per year to Temple.  These compounds have been evaluated
in various academic and government laboratories.

In December, 1999, the Company 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 the Company's 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 the
Company's products.  In addition, Biovail agrees to work with the
Company in preparing and filing of a New Drug Submission with
Canadian Regulatory Authorities.  Biovail invested several million
dollars in Hemispherx equity at prices above the then current market
price and agreed to make further payments based on reaching certain
regulatory milestones.  The Agreement requires Biovail to penetrate
certain market segments at specific rates in order to maintain
market exclusivity.

Competition

There are several publicly held companies that place emphasis on
nucleic acid technology.  Some are outlined below from publicly
available documents filed with the Securities and Exchange
Commission.

Gilead Sciences, Inc. (Foster City, California; GILD/NASDAQ). Gilead is

<PAGE>
<PAGE> 14
developing nucleotide as well as other innovative antiviral
technologies and is pursuing pre-clinical and clinical development
of a number of therapeutic product candidates for treating certain
viral diseases including, without limitation, cytomegalovirus
retinitis, HIV and Hepatitis B.  Gilead reports that they have
investigational drug products in Phase II clinical trials for
treating Hepatitis B and Phase III for treating HIV.  The FDA
recently granted a Fast Track designation to a Gilead product, but
marketing approval of this product was subsequently withdrawn.

ISIS Pharmaceuticals, Inc. (Carlsbad, California; ISIS/NASDAQ). This
company, founded in 1989, has devoted substantially all of its
resources to research, drug discovery and development programs.
Isis currently has one product, Vitravene, a treatment for CMV
Retinitis in AIDS patients, which has achieved limited market
acceptance in a small commercial market with significant
competition.  Isis reports that most of their resources are being
dedicated to applying molecular biology and medicinal chemistry to
discovery and development of drug candidates based upon antisense
technology.

The Company anticipates that it may face increased competition in
the future as new products enter the market and advanced
technologies become available.  There can be no assurance that
existing products or new products developed by the Company's
competitors will not be more effective than any that may be
developed by the Company.  Competitive products may render the
Company's technology and products obsolete or noncompetitive prior
to the Company's recovering research, development or
commercialization expenses incurred with respect to any such
products.

Many of the Company's existing or potential competitors have
substantially greater financial, technical and human resources than
the Company.  In addition, many of these competitors may have
significantly greater experience than the Company in undertaking
certain aspects of research, preclinical studies and human clinical
trials of new pharmaceutical products, obtaining FDA and other
regulatory approvals, and manufacturing and marketing such products.
Accordingly, the Company's competitors may succeed in
commercializing the products more rapidly or more effectively than
the Company.

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 the Company's proposed products and in its ongoing
research and

<PAGE>
<PAGE> 15
product development activities.  The Company's existing
product and the products of its ongoing research and product
development activities will require regulatory clearances prior to
commercialization. In particular, human new drug products are
subject to rigorous preclinical and clinical testing as a condition
of 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 the Company or
its 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.  The Company has received orphan drug
designation for certain therapeutic indications which might, under
certain conditions, accelerate the process of drug
commercialization.

The Company has not received a "Fast-Track" designation for any
of its potential therapeutic indications.  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.  The Company will continue to present data in
support of obtaining a fast-track designation; the Company has
not yet submitted any New Drug Application (NDA) to a North
American regulatory authority.  There are no assurances that such
designation will be granted, or if granted, there are no
assurances that such designation will materially increase the
prospect of a successful commercial application.  The Company
submitted an emergency treatment protocol for clinically-resistant
HIV patients which was withdrawn by the Company during
the statutory approximately 30 day regulatory review period in
favor of a set of individual physician-generated applications
which are under review.  There are no assurances that
authorizations to commence such emergency treatments will be
granted by any regulatory authority or that the resultant
treatments, if any, will support drug efficacy and safety.  The
Company also has a Phase II HIV treatment protocol in which the
Company's drug was combined with certain presently available
antiretroviral agents;  this application was deemed deficient
because: a) important adverse reactions known to be associated
with these agents [14 approved antivirals] were not adequately
addressed in the protocol and no clinical rationale was provided
for specific choice of antiretroviral drugs included in the
treatment regimen.  The Company intends to address these issues
but no assurances can be given that such answers will materially
increase the prospect of a successful study or of a successful
commercial application, if submitted thereafter.

The Company is also subject to various federal, state and local
laws, regulations and recommendations relating to such matters as
safe working conditions,

<PAGE>
<PAGE> 16
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 the Company's research work. The Company believes
that its Rockville, Maryland manufacturing and quality
assurance/control facility is in substantial compliance with all
material regulations applicable to these activities.  However,
the Company cannot give assurances that facilities owned and
operated by third parties, that are utilized in the manufacture
of the Company's products, are in substantial compliance, or if
presently in substantial compliance, will remain so.  These
facilities include manufacturing operations in San Juan, Puerto
Rico, Capetown, South Africa, and Columbia, Maryland, and
Melbourne, Australia.

Human Resources

The Company had 48 employees as of February 29, 2000 of which 20 are
full time

and 28 are utilized on a part-time basis.  Such parties
are paid on a per diem or monthly basis.  Thirty-one of our
employees are engaged in the Company's research, development,
clinical, manufacturing effort, including 2 individuals in Europe.
Twenty of our employees perform regulatory, general administration,
data processing, including biostatistics, financial and investor
relations functions.  The Company believes that this arrangement
provides the most efficient approach to drug development at this
point in time.  While the Company has 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.

Year 2000 Project

Since mid-1998, the Company has replaced and upgraded all computers
and software programs deemed to be non Y2K compliant.  The new
hardware/software used in Administration, Finance and Research &
Development has been tested and proven to be Y2K compliant.  The
critical databases have been converted to the new system and are
operating.  As a back-up for the first few months, the computer
network was being run in parallel with the new system.  The Company
discontinued the parallel operation on December 31, 1999.

As of December 31, 1999, the Company had received assurances from
all critical suppliers/vendors that they were Y2K compliant and that
the Y2K issue would not affect their ability to supply goods and/or
services after December 31, 1999.

The Company has incurred over $200,000 for hardware and software
needed to become Y2K compliant since mid-1998.

The Company has not, and does not expect to experience any
operational or financial problems relating to the Y2K matter.

Forward-Looking Statements and Risk Factors

Any statements in this Annual Report on Form 10-K, as amended about
our expectations, beliefs, plans objectives, assumptions or future
events or performance are not historical facts and are forward
-looking statements.  These statements are often, but not always,
made through the use of words or phrases such as "will continue,"
"anticipate," "estimate," "intend," "plan," "projection," "would,"
"should," and "outlook." Accordingly, these statements involve
estimates, assumptions and uncertainties which could cause actual
results to differ materially from those expressed in them.  Any
forward-looking statements are qualified in their entirety by
reference to the factors discussed throughout this Report, as
amended, for the year ended December 31, 1999.  The following
cautionary statements identify important factors that could cause
our actual results to differ materially from those projected in
the forward-looking statements made in this prospectus.  Among the
key factors that have a direct bearing on our results of operations are:

* General economic and business conditions; the existence or absence
  of adverse publicity; changes in, or failure to comply with, government
  regulations; changes in marketing and technology; change in political,
  social and economic conditions;
* Increased competition in the biopharmaceutical industry; general risk
  of biopharmaceutical industry;
* Success of acquisitions and operating initiatives; changes in business
  strategy or development plans; management of growth;
* Availability, terms and deployment of capital;
  Construction schedules; costs and other effects of legal and
  administrative proceedings;
* Dependence on senior management; business abilities and judgement of
  personnel; availability of qualified personnel; labor and employee
  benefit costs;
* Development risks; risks relating to the availability of financing; and
  The following and other factors referenced in this Report including:

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 of December 31,1999 our accumulated deficit was approximately
$71,000,000.  We have not yet generated significant revenues from our
products and may incur substantial and increased losses in the future.
We cannot assure you 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 you 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.

<PAGE> 18
	Additional Financing Requirements.

	The development of our products has required and will continue to
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 and to establish commercial-sale
production and marketing capabilities.  Based on our current operating plan,
we anticipate receipt of limited revenues form the sales of Ampligen under
the Cost Recovery Clinical Programs and investors exercising the Class A
Redeemable Warrants, which we believe will be sufficient to meet our capital
requirements for the near future.  The Company may need to raise substantial
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 its products.

     No regulatory agency has approved the full commercial sale of any of
the Company's products.

	We cannot assure you that Ampligen will ultimately be demonstrated
to be safe or efficacious.  While Ampligen 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.  We cannot assure you that Ampligen will be
commercially successful in any country that may approve its use.  If Ampligen
or one of our other products does not receive regulatory approval in the
United States or elsewhere, our operations will be significantly affected.

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

	We need to acquire enforceable patents covering the use of Ampligen
for a particular disease in order to obtain exclusive rights for the
commercial sale of Ampligen for such disease. Our success depends, in
large part, on our ability to obtain patent protection for our products
and to obtain and preserve our trade secrets and knowhow. We have been
issued certain patents on the use of Ampligen and Ampligen in combination
with certain other drugs for the treatment of HIV.  We have also been
issued patents on the use of Ampligen 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 in
patients with chronic fatigue syndrome.  We have not been issued any
patents in the United States for the use of Ampligen as a sole treatment
for any of the cancers which we have sought to target.  Our applica-tions
for United States patents for the use of Ampligen in the treatment of renal
cell carcinoma and lung cancer are currently pending.  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 Ampligen in combination
with various other agents, including AZT, for a particular target indication
prior to us.  If we cannot protect our patents covering the use of Ampligen
for a particular disease, or obtain additional pending patents, we may not
be able to successfully market Ampligen.

<PAGE> 19
	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 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 the intellectual property
rights and that such litigation could requires substantial resources from us.
No assurance':can be made that our patents will provide competitive advantages
for our products or will not be successfully challenged o circumvented by our
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
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 have the financial resources
necessary to enforce patent rights we may hold.

	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 commercial by reasonable terms, if at all. We 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 rights they may have Or that the rights, if any,
retained by the government will not adversely affect the value of our license.
Certain of our 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 do not expect to be profitable unless we receive final regulatory
Approval for Ampligen and it is successfully commercialized.

	Ampligen has not been approved for commercial use in the United
States or elsewhere.  We do not expect to be profitable unless we receive
final regulatory approval and can successfully commercialize Ampligen or
one of our other products. Our products, including Ampligen, are subject
to extensive regulation by numerous governmental authorities in the United
States and other countries, includ-ing, but not limited to, the Food and
Drug Administration in the United States, the Health Protection Branch of
Canada's Department of Health and Welfare, a federal regulatory agency in
Canada, and the European Medical Evaluation Agency in Europe.  Obtaining
regulatory approval is a rigorous and lengthy process- and requires the
expendi-ture of substantial resources.  In order to obtain final regulatory
approv-al of a new drug, we must demonstrate to the satisfaction of the
regulatory agency that the product is safe and effective for its intended
use and that we are capable of manufacturing the product to the applicable
regulatory standards. We require regulatory approval in order to market our
products and receive product revenues or royalties.

<PAGE> 20

	We may not be profitable unless we can produce Ampligen in commercial
quantities at costs acceptable to us.

	We have never produced Ampligen or any other products in large
commercial quantities.  Ampligen is currently produced only for use in
clinical trials.  We must manufacture our products in compliance with
regulatory requirements at 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
facili-ties.  If we cannot manufacture commercial quantities of Ampligen
or enter into third party agreements for its manufacture at costs acceptable
to us, our operations will be significantly affected.

	If our distributors do not market our product successfully, we may
notgenerate 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
prod-ucts 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 and Austria.

	Gentiva Health Services is able to deliver treatment and services to
chronic disease patients including infusion services, home nursing and other
medical services through a national network of more than 500 locations.  We
cannot assure you that Gentiva Health Services 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. We are
dependent upon certain third party suppliers for key components of the
proposed products and for substantially all of the production process. If
we cannot enter into future marketing and distribution agreements at terms
acceptable to us, or if these distributors cannot effectively market and
distribute our products, our operations will be negatively affected.

<PAGE> 21
	No Assurance of Successful Product Development.

	The development of new pharmaceutical products is subject to a
number of  significant risks. Potential products that appear to be promising
at an early stage of research or development may not reach the market for a
number of reasons. Potential products 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 rights of third parties.
Our products are in various stages of clinical and pre-clinical development;
each will need to progress through further clinical studies and appropriate
regulatory approval processes before any such products can be marketed.
We do not know when, if ever, Ampligen will be available for commercial sale
for any indication. Generally, only a small percentage of potential
therapeutic products are eventually approved by the FDA for commercial sale.
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 efforts 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.

	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 and other such RNA drugs, as well as their safety and
efficacy. Changes in methods of manufacture, including commercial scale-up
may affect the chemical structure of Ampligen and, can, among other things,
require new clinical studies.

	Rapid Technological Change.

	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.

<PAGE> 22
	Substantial Competition.

	Competitors have developed or are in the process of developing
technologies that are, or in the future may be, the basis for competitive
products. Some of these 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 will offer competition to the 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 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.

 	Limited Manufacturing Experience and Capacity.

	Ampligen is currently produced only in limited quantities for use
in its clinical trials. 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 Good
Manufacturing Practices regulations. There can be no assurance that
such facilities can be used, built, or acquired on commercially acceptable
terms, that such facilities, if used, built, or acquired, will be adequate
for our long-term needs.

	We may be subject to product liability claims from the use of
Ampligen 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 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 be negatively affected from the
litigation costs, settlement expenses and lost product sales inherent
to these claims.  While we will continue to attempt to take appro-priate
precautions, we cannot assure you that we will avoid significant product
liability exposure.  Although we currently maintain worldwide product
liability insurance coverage in the amount of $1,000,000, there can be
no assurance that this insurance will provide adequate coverage against
product liability claims.  While no product liability claims are pending
or threatened against us to date, a successful product liability claim
against us in excess of our insurance coverage could have a negative effect
on our business and financial condition.

<PAGE> 23
	Members of our Scientific Advisory Board have conflicting interests
and may disclose  data and technical knowhow to our competitors.

	Some of our Scientific Advisory Board members are employed by other
entities, which may include our competitors.  Although we require each of
our Scientific Advisory Board members to sign a non-disclosure and non-
competition agreement with respect to the data and information that he or
she receives from us, we cannot assure you that members will abide by them.
If a member were to reveal this information to outside sources, accidentally
or otherwise, our operations could be negatively affected.  Since our
business depends in large part on our ability to keep our knowhow
confidential, any revelation of this information to a competitor or other
source could have an adverse effect on our operations.

	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.

	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.  The loss of Dr. Carter's services could have a material adverse
effect on our operations.  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 key personnel,
such as Dr. David Strayer or Dr. Carol Smith, or the failure to recruit
additional personnel as needed could have a materially adverse affect on
our ability to achieve our objectives.

	Uncertainty of Health Care Reimbursement and Potential Legislation.
	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. Our potential products represent a new mode of therapy,
and we expect that the costs associated with purchasing and administering
our products will be substantial. There can be no assurance that our
proposed products, if successfully developed, will be considered cost
effective to third-party payors, that reimbursement will be available or,
if available, that the timing and amount of such, reimbursement will not
adversely affect our ability to sell its products on a profitable basis.

<PAGE> 24
	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. The company does not maintain insurance coverage against such
liabilities.

	Exercise of Class A Redeemable Warrants May Have Dilutive Effect on
Market.

	Holders of the lass A Redeemable Warrants may exercise the class A
Redeemable Warrants and purchase the underlying Common Stock at a time when
the Company might be able to obtain capital by a new offering of securities
on terms more favorable than that provided by the exercise of such Class A
Redeemable Warrants, in which event our ability to obtain additional capital
would be affect-ed adversely.

	Ampligen Safety Profile.

	We believe that Ampligen has been generally well tolerated in 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
[rythema,] a tightness of the chest, tachycardia, 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 adv se side effects include liver enzyme
level elevations, diarrhea, itching, urticaria (swelling of the skin),
bronchospasm, transithypotension, photophobia, rash, bradycardia, transient
visual disturbances, arrhythmias, decreases 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, j int pains, headaches,
nausea and vomiting. These flu-like side effects typically subside within
several months.

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 of
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 of 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.

Executive Officers

The executive officers of the Company, whose terms will expire
at such time as their successors are elected, are as follows:

ITEM 2.  Properties

The Company leases and occupies a total of approximately 18,850
square feet of laboratory and office space in two states. The
corporate headquarters in Philadelphia, Pennsylvania are located in
a suite of offices of approximately 15,000 square feet. The
pharmacy, packaging, quality assurance and quality control
laboratories, as well as additional office space, are located in
Rockville, Maryland. These facilities occupy approximately 3,850
square feet, approximately 2,000 of which are dedicated to the
packaging and quality control product release functions. The Company
believes that its Rockville facilities will meet its production
requirements, including sufficient quantities of Ampligen for
planned clinical trials and treatment protocols, through 2000, after
which time it may need to increase its manufacturing capacity either
through third parties or by building or acquiring commercial-scale
facilities.

In addition, the Company has entered into the Bioclones Agreement,
which provided the Company with 24.9 % of the capital stock of
Ribotech, Ltd to develop and operate a new manufacturing facility
which is financed by Bioclones.  Manufacturing at the pilot facility
commenced in 1996. The Company expects that Ribotech will start
construction on a new commercial production facility in 2001,
although no assurance can be given that this will occur. The Company
has no obligation to fund this construction.

ITEM 3.  Legal Proceedings

Ell & Co., and the Northern Trust Company, as Trustee of the AT&T
Master Pension Trust filed a complaint against the Company in the
Court of Chancery of the State of Delaware in and for New Castle
County on September 23, 1998.  This complaint alleges that the
Company breached its contractual obligations as set forth in the
Certificate of Powers, Designations, Preferences and Rights of the
Series E Convertible Stock.  The Plaintiff seeks to enforce its
rights to convert 1,500 shares of Series E Preferred Stock into
750,000 shares of freely traded common stock and to recover damages
for its inability to convert the preferred stock when it requested
to do so.  Although the Company maintains that the 1,500 shares of
Series E Preferred Stock had been properly redeemed and, therefore,
the plaintiff was not contractually able to effect a proper
conversion into common shares, the Company agreed in December, 1998
to convert the plaintiffs preferred stock to common stock.  In
February 2000, the plaintiffs dropped the lawsuit.

On September 30, 1998, the Company filed a multi-count complaint
against Manuel P. Asensio, Asensio & Company, Inc., and others in
the United States District Court for the Eastern District of
Pennsylvania.  On October 22, 1998, the Company

<PAGE>
<PAGE> 28
amended the complaint to add additional counts and to conform the
complaint to agreed upon dismissals without prejudice as to certain
of the defendants.  On August 13, 1999, the Company amended and
supplemented the complaint for a second time to conform the
complaint to court ordered dismissals of certain counts of the
complaint and parties, to add Asensio.com, Inc. (formerly known as
Asensio Holdings, Inc.), the holding company of defendant Asensio
Company Inc., and to add a conspiracy charge against the remaining
defendants and certain unnamed John Does.

The complaint presently contains claims of defamation,
disparagement, tortious interference with existing and prospective
business relations and conspiracy, arising out of the current
defendants' false and defamatory statements. (The complaint further
alleges that defendants defamed and disparaged the Company in
furtherance of a manipulative, deceptive and unlawful short-selling
scheme between August, 1998, and the present.

On April 19, 1999, defendants Asensio and Asensio & Company, Inc.,
filed an answer and counterclaim against the Company.  The
counterclaim alleges that on or about September, 1998, and in
response to defendants' strong sell recommendation and other press
releases about Hemispherx and its officers and directors, the
Company made defamatory statements about defendants, including that
defendants' attacks and manipulative short-selling scheme may have
constituted criminal wrongdoing on the part of defendants.  The
Company has denied the material allegations of the counterclaim and
is vigorously defending against the counterclaim.  In August, 1999,
several of the short sellers in Hemispherx were indicted by the U.S.
Attorney in New York for money laundering and manipulation in
another non-Hemispherx matter.  The parties are presently engaged in
discovery with a trial date of May 1, 2000.

In October, 1998, the Company contacted the SEC regarding what it
believed may have been illegal short selling and unlawful market
manipulation in furtherance of the short selling of Manuel P.
Asensio and others.  Thereafter, in April, 1999, the Company was
advised by the Securities and Exchange Commission ("SEC") of a
private investigation into various allegations of misrepresentations
by the Company and its officers.  Specifically, the SEC sought
information relating to allegations about the Company's
investigational drug application for treatment of various diseases,
results of clinical research, incidence of ME/CFS in the United
States, the Company's patents, and Ampligen's safety and efficacy.
These allegations had also been included by Asensio & Co. in its
various "research reports."  The SEC has declined to be more
specific about the nature or substance of the investigation.  The
Company is cooperating fully with the investigation.

<PAGE>
<PAGE> 29
The Company has also been advised that the NASD has initiated an
investigation into the short selling of Hemispherx Securities (Enf-303).
Asensio has admitted, in deposition testimony in the
Company's litigation against him, that he and his company was the
subject of such an investigation.  Hemispherx is also cooperating
with the NASD in its investigation of the short selling of its
stock.

On March 6, 2000, Cook Imaging Corp, et al filed a complaint against
the Company in the United States District Court for the Eastern
District of Pennsylvania.  Cook Imaging Corp., asserts that the
Company refuses to pay for certain Ampligen manufacturing efforts by
Cook.  The Company maintains that Cook Imaging Corp., did not
perform as required by the contract.  The Company plans to respond
to the complaint and defend against the charges.

ITEM 4.  Submission of Matters to a Vote of Security Holders

     None.

                              PART II

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

In October, 1997, the Company's Common Stock and Class A Warrants
commenced trading on the American Stock Exchange under the symbols
HEB and HEB/ws, respectively.  Simultaneously these securities were
delisted from NASDAQ.  The securities had traded on NASDAQ since the
IPO in November, 1995.

In February, 1998, the Company filed a Registration Statement with
the Securities and Exchange Commission (SEC) to register the common
stock placed in the September 1997 private placements.  The
statement included common stock underlying certain stock purchase
warrants with registration rights.

In July, 1998, the Company's Common Stock and Class A Warrants were
listed on the Berlin Stock Exchange.  The shares and warrants will
trade under the symbols HXB and HXBA respectively.  The listing on
the Berlin Stock Exchange has been facilitated by Berliner
Freiverkehr, a major German investment banking and brokerage firm,
with assistance from Value Management & Research, GmbH, a European
based Research and Investment Firm.

In April, 1999, the company filed a Registration Statement with the
Securities and Exchange Commission (SEC) to register the common
stock privately placed in July, 1998.  In addition, certain warrants
and underlying common stock was included in the Registration.

<PAGE>
<PAGE> 30
In June 1999, the Company filed a registration statement on Form S-3
with the SEC registering certain warrants and the shares of Common
Stock underlying those warrants on behalf of certain warrantholders.
The Company has entered into agreements with certain of the
warrantholders providing for, among other things, (a) an escrow and
conditional lockup of one year from the effective date of the
registration statement; and (b) the sale of such warrantholders'
warrants during such one year lockup through an agent or by the
Company at prices set by the warrantholders.  On September 29, 1999,
the Registration Statement was amended.  This amended document
became effective on October 1, 1999.

In 1999, the Company acquired 290,811 shares of Common Stock on the
open market at an average cost of $6.76 per share.  This acquisition
is part of the share buy back program authorized by the Board of
Directors.  These shares may be retired in part thereby reducing the
number of shares outstanding.  Certain shares of the Company's
Treasury Stock may be utilized to fund acquisitions, strategic
alliances, or to obtain equity positions in other companies in order
to potentially increase the breadth and depth of the Company's drug
technology portfolio including the Company's potential position in
the emerging area of human genomics.

The foregoing private offerings were private transactions and exempt
from registration under section 4(2) of the Securities Act pursuant
to regulation D of the Act.  All investors in these transactions are
accredited.

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

The following discussion should be read in conjunction with the
consolidated financial statements and notes thereto, which are
included herein.

<PAGE>
<PAGE> 34
Background

Since 1980, the Company has raised funds of some $150,000,000 from equity
and debt financing which has been used in research and development of its
Nucleic Acid Technologies.  Nucleic Acid compounds represent a new class
of pharmaceutical products designed to act at the molecular and genetic
level for the definitive treatment of certain devastating human diseases.
The Company's platform technology utilizes specifically configured
ribonucleic acids ("RNA") which are broadly protected by a patent estate
consisting of more than 300 patents.  One of the Company's double-stranded
RNA drug products, trademarked "Ampligen", is in advanced human clinical
development for various therapeutic indications.  Based on the results of
pre-clinical and clinical trials, the Company believes that Ampligen may
have broad spectrum anti-viral and anti-cancer potential.  Over 400
patients have participated in clinical trials authorized by the Food and
Drug Administration ("FDA") at some twenty clinical sites across the
United States, representing the administration of more than 40,000 doses.

In October, 1998, the Company initiated a Phase III trial for the
treatment of 230 patients afflicted with Myalgic Encephalomyelitis/Chronic
Fatigue Syndrome ("ME/CFS") at various medical centers in the United
States.  In parallel, the Company is conducting cost recovery treatment
programs for ME/CFS patients in the United States, Canada, Belgium and
Austria.  The treatment program in the U.S. was expanded by FDA
authorization in early 1999.  In December, 1998, the Company completed and
filed a full marketing application for approval to treat ME/CFS patients
in the European Union.

The Company is actively engaged in various market development strategies
in the United States and European Union, as well as other countries
including Canada, Australia and South Africa.  Disease categories under
active development include ME/CFS, hepatitis and HIV.  The Company
maintains offices and clinical operations in both the United States and
European Union, as well as ownership interests in a related European based
diagnostic company and in a South African manufacturing entity which
produces its raw drug materials.

The Company has reported net income only from 1985 through 1987. Since
1987, the Company has incurred substantial operating losses. Prior to
completing an Initial Public Offering ("IPO") in November 1995, the
Company financed operations primarily through the private placement of
equity and debt securities, equipment lease financing, interest income and
revenues from licensing and royalty agreements.

The consolidated financial statements include the financial statements of
Hemispherx BioPharma, Inc. and its four wholly-owned subsidiaries, BioPro
Corp., BioAegean Corp., Core BioTech Corp. and Hemispherx Biopharma-Europe
NV/SA.  The U.S. subsidiaries were incorporated in September 1994 for the
purpose of developing technology for ultimate sale into certain
nonpharmaceutical specialty consumer markets.  The European subsidiary was

<PAGE>
<PAGE> 35
formed for the purpose of serving the Company's needs with respect to
pursuing clinical trials and regulatory approval in the European Union.
All significant intercompany balances and transactions have been
eliminated in consolidation.

The Company expects to continue its research and clinical efforts for the
next several years with some benefit of certain revenues from cost
recovery treatment programs, notably in Belgium, Canada and the U.S..
Beginning in 1994, limited revenues were initiated in Belgium from sales
under the cost recovery provision for conducting treatment clinical tests
in ME/CFS; including the United States these sales were $678,248 in 1999.
The Company may continue to incur losses over the next several years due
to clinical costs which may be partially offset by expanded access cost
recovery revenues and potential licensing fees. Such 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
revenues.  Acquisition of full or conditional marketing approval in any
major market would significantly affect the Company's cash flow.  There
are no assurances that such approvals will ever happen in any major
pharmaceutical market.

RESULTS OF OPERATIONS

Years Ended December 31, 1999 vs. 1998

The Company reported a net loss of $9,201,227 (including a non-cash loss
of $1,520,650 for stock compensation expense) for the year ended December
31, 1999 versus a net loss of $7,324,093 for the same period in 1998.
Several factors contributed to the $1,877,134 increase in net losses in
1999.  In general, non-operating stock compensation expense, increased
clinical costs and legal fees account for the increase in net losses.

Revenues from the Company's Cost Recovery Treatment Program in the United
States and Europe were up by $277,540 in 1999 versus 1998.  The Company
expects these programs may expand in the year 2000, especially in Europe
where efforts are being organized to increase the expanded access program
to other European countries.  At present, these programs are operational
in Belgium and Austria.

In 1999, clinical trial costs increased $917,913 primarily due to
increased activity in the AMP 516 ME/CFS clinical trial initiated by the
Company in October, 1998.  Manufacturing and related costs were $1,503,455
in 1999 versus $1,923,001 in 1998.  The 1998 costs reflects the build-up
of drug inventories needed to support clinical trial and other research
and development efforts.  At present, the Company expenses all raw
material and related production costs as incurred.

General and administrative expenses were up $1,146,039 in 1999 versus
1998.  Legal expenses for attorneys increased $602,531 primarily due to
litigation associated with the Asensio & Company lawsuit, the ELL & Co.
lawsuit, settlement of the VMW lawsuit and other legal matters.  Expenses
associated with stock transactions, registration statements and financing
were up $156,277.  The cost of funding the European Operation was up by
$187,005 in 1999 due to establishing and some staffing of the Company's
European Subsidiary.  The cost of evaluating the feasibility of the spin-off of
the Company's wholly owned subsidiary was $116,028 more than
expensed in 1998.

Stock compensation expense was $1,520,650 for 1999 versus $794,747
recorded for 1998.  Stock compensation expenses reflect the fair value of
the common stock including the warrants granted to non-employees of the
Company.  The increase in 1999 reflects warrants granted to consultants
for various types of assistance and professional services provided to the
Company.

<PAGE>
<PAGE> 37
Years Ended December 31, 1998 vs. 1997

The Company reported a loss of $7,324,093 in 1998 versus a loss of
$6,106,860 in 1997. Several factors contributed to the increased loss of
$1,217,233 in 1998.

Revenues increased by $141,993 in 1998 due to the increased enrollment of
patients
in the cost recovery treatment programs being conducted in Belgium, Canada
and the United States.

Research and development costs increased $1,386,860 in 1998 due primarily
to increased spending to start up the Phase III ME/CFS clinical trial in
the United States.  In addition, the Company built up the inventory of
Ampligen raw materials and finished goods in anticipation of the drug
needs to support the Phase III clinical trial.  All costs incurred were
part of the Company's plan to enhance the clinical data required to
support the eventual full marketing application in the United States and
European Union.

General and administration expenses totaling $2,957,831 in 1998 increased
$762,886 over the prior year.  Litigation issues that arose in 1998 caused
an increase in legal fees by approximately $300,000.  Preparation and
Filing of the European Union new drug application resulted in consultant
and related expenses to increase a total of $109,784, public
relations/shareholder communications expense increased by some $200,000 as
the Company responded to various charges brought by short sellers (see
Asensio Litigation) and administrative expenses supporting clinical trials
increased $69,000.

Consulting Stock Compensation Expense of $794,797 in 1998 relates to the
stock value of warrants granted to consultants engaged to assist the
Company on various financial, stock market and other matters.

Preferred stock conversion expense of $1,200,000 in 1997 primarily
resulted from the inducement to effect the early redemption of the Series
D Preferred Stock.  The Company gave the Preferred Stockholder 200,000
shares of common stock with a guaranteed sales price of $6 per share.

Interest income was $590,085 in 1998 versus $267,291 in 1997.  While
overall short-term interest rates were lower than those experienced in
1997, the amount of unused funds available for short-term investing was
greater causing the increase in interest income.

Liquidity and Capital Resources

Cash, cash equivalents and short term investments at December 31, 1999 was
$8,549,389 reflecting a net use of cash totaling $5,628,650 in 1999.
Operating activities used $6,989,791.  Non-operating expenditures totaled
$1,871,734.  Cash proceeds include $1,969,272 from private placements of
the Company stock and $1,923,473 from

<PAGE>
<PAGE> 38
warrantholders exercising warrants.

Cash used for non-operating items include $1,966,548 used to acquire
290,811 of the Company's common stock pursuant to a share buy-back program
approved by the Company's Board of Directors.  The Company privately
placed 150,000 of these shares producing proceeds of $1,329,495.

In addition, the Company spent $375,000 to acquire an interest in an
unconsolidated affiliate.  $478,022 was spent on equipment (primarily
computers and software) and patents.

The Company's operating cash burn rate for the last six months of 1999 was
approximately $589,000 per month.  All clinical trial drug products were
fully expensed although some are expected to be sold under the expanded
access,-recovery, pre-marketing programs authorized by FDA and various
regulatory bodies in other countries.  As the clinical testing effort in
the United States accelerates and the European market development activity
increases, the operating burn rate may increase periodically.  However,
certain of the operating, as well as the non-operating cash outlays are of
a one time nature and are expected to decline significantly.  Also
revenues from expanded access product sales is expected to continue to
increase in the coming year.

The Company expects warrant holders to continue exercising the Class A
redeemable warrants and private warrants from time to time depending on
the trading price of the Company common stock.  As of December 31, 1999,
the Company has 5,480,310 Class A redeemable warrants outstanding.  These
warrants can be exercised at $4.00 per share.  In addition, there are
462,000 Class A redeemable warrants outstanding at an exercise price of
$6.60 per share.  Non-public warrants outstanding total 8,065,700 with a
weighted average exercise price of $3.67.

Because of the Company's long-term capital requirements, it may seek to
access the public equity market whenever conditions are favorable, even if
it does 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. The Company may also need additional funding
earlier than anticipated, and the Company's cash requirements in general
may vary materially from those now planned, for reasons including, but not
limited to, changes in the Company's 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 the Company's clinical trials for which cost
recovery from participants has been approved.

<PAGE> 39
New Accounting Pronouncements

On December 31, 1999, the Securities and Exchange Commission, or SEC,
issues Staff Accounting Bulletin No. 101, "Revenue Recognition in
Financial Statements," or SAB No 101.  SAB No. 101 provides the SEC
staff's views on the recognition of revenue including nonrefundable
technology access fees received by biotechnology companies in connection
with research collaborations with third parties.  SAB No. 101 states that
in certain circumstances the SEC staff believes that up-front fees, even
if nonrefundable, should be deferred and recognized systematically over
the term of the research agreement.  SAB No. 101 requires registrants to
adopt the accounting guidance contained therein by no later than the second
fiscal quarter of the fiscal year beginning after December 15, 1999.  The
adoption of this standard should not have a material impact on the
Company's financial position of results of operations.

In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, Accounting for Derivative Instruments and Hedging Activities
("Statement 133").  Statement 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities.
Statement 133 requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure
the instrument at fair value.  The accounting changes in the fair value of
a derivative depend on the intended use of the derivative and the
resulting designation.  This Statement, as amended, is effective for the
first fiscal quarter beginning after December 31, 2000.  The adoption of
this standard will not have a material impact on the Company's earnings or
financial position.

ITEM 7a.  Quantitative and Qualitative Market Risk

Market Risk

The Company had $8.5 million in cash and cash equivalents at December 31,
1999.  To the extent that the Company's cash and cash equivalents exceed
its near term funding requirement, the Company invests the excess cash on
3 to 6 months high quality financial instruments.  The company employs
established policies and procedures to manage any risks with respect to
any investment exposure.

ITEM 8.  Financial Statements and Supplementary Data

The Company's consolidated balance sheets as of December 31, 1998 and
1999, consolidated statements of operations, changes in stockholder's
equity (deficit) and comprehensive loss and cash flows for each of the

                   Independent Auditors' Report


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, 1998 and 1999, and the related consolidated statements of
operations, changes in stockholders' equity and comprehensive loss
and cash flows for each of the years in the three-year period ended
December 31, 1999. 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 generally
accepted auditing standards. 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, 1998 and 1999, and the results of their
operations and their cash flows for each of the years in the
three-year period ended December 31, 1999 in conformity with
generally accepted accounting principles.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1998 AND 1999

(1) Business

Hemispherx BioPharma, Inc. and subsidiaries (the Company) is a
pharmaceutical company using nucleic acid technologies to develop
therapeutic products for the treatment of viral diseases and
certain cancers. The Company's drug technology uses
specially-configured ribonucleic acid (RNA). The Company's
double-stranded RNA drug product, trademarked Ampligen, is in human
clinical development for various therapeutic indications.  The
potential efficacy and safety of Ampligen is being evaluated
clinically for three anti-viral indications: myalgic
encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS),
human immunodeficiency virus associated disorders, and chronic
hepatitis B virus infection.  The Company also has clinical
experience with Ampligen in patients with certain cancers including
renal cell carcinoma (kidney cancer) and metastatic malignant
melanoma.  The Company has other compounds to be evaluated.

The consolidated financial statements include the financial
statements of Hemispherx BioPharma, Inc. and its wholly-owned
subsidiaries BioPro Corp., BioAegean Corp. and Core BioTech Corp.
which were incorporated in September 1994, and Hemispherx
Biopharma-Europe which was incorporated in August 1998.  All
significant intercompany balances and transactions have been
eliminated in consolidation.

On November 7, 1995, the Company completed an initial public
offering (IPO) of 5,312,900 units of Hemispherx BioPharma, Inc.
resulting in net proceeds of approximately $15.8 million.  Each
unit consists of one share of the Company's Common Stock and one
Class A Redeemable Warrant, exercisable for one share of Common
Stock at $4.00 per share.  These Class A Redeemable Warrants are
subject to redemption by the Company beginning November 2, 1997 at
$.05 per warrant in the event that the closing bid price of the
Company's Common Stock exceeds $9.00 for a specified time period.
In connection with the IPO, the underwriter was granted an option
to purchase 462,000 units at $5.775 per unit.

On May 1, 1997, the Company received permission from the U.S. Food
and Drug Administration (FDA) to recover costs from Chronic Fatigue
Syndrome (CFS) patients in the Company's AMP-511 open-label
treatment protocol.  The cost of Ampligen to the patient is $2,100
for the first eight weeks of treatment and $2,400 for each
additional eight-week period thereafter.  Approximately 70 ME/CFS
patients were enrolled under this treatment protocol at various
clinical centers in the U.S as of February, 2000.

In the second quarter of 1998, the Company initiated the
recruitment of clinical investigator and ME/CFS patients to
participate in the confirmatory Phase III placebo-controlled
clinical study of Ampligen  in the treatment of persons suffering
from ME/CFS.  The Company has a target of eventually enrolling 230
patients with the severely debilitating form of ME/CFS.  In August,
1998, the Company started enrollment of patients into the pre-clinical or
baseline phase of the study.

In December 1998, the Board of Directors explored the aspects of
spinning off Core Biotech, Inc., a wholly owned subsidiary to its
shareholders in a tax free transaction.  Core Biotech Corp. intends
to use genetic technologies to develop therapeutic products for the
treatment of viral hepatitis diseases.  The purpose of the spin-off
would be to allow shareholders to realize value for an asset that
the Company believes is not currently being appropriately valued.
No final determination has been made with respect to
capitalization, pro forma financial information, management or
intercompany transactions.  The timetable for the planned spin-off
would depend on financing, staffing market conditions and progress
in developing the Company's other technologies.  At this time, the
Company has put this project on hold and expects to re-open the
matter in early summer, 2000.

(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 $12,025,073 and $6,396,423 at December 31,
1998 and 1999, respectively.

(b) Investments

The Company classifies investments with original maturities of
three months or less as cash equivalents. Investments with original
maturities of more than three months are considered available for
sale. The investments classified as available for sale are payable
notes and are carried at estimated fair value with unrealized gains
and losses recorded as a component of shareholders' equity.

In 1998, the Company acquired 3.3% of the issued and outstanding
common stock of R.E.D. Laboratories at a cost of $1,038,000.
R.E.D. Laboratories is developing a diagnostic test for the ME/CFS
disease. In 1999, the Company acquired 15% of the equity stock of
the California Institute of Molecular Medicine (CIMM) for $375,000.
CIMM is developing therapy for Hepatitis C virus.  Such investments
are accounted for on the cost basis of accounting.

(c) Property and Equipment
                                                    1998       1999
                                                    ----        ----
        Furniture, fixtures, and equipment        $767,271  $1,018,293
        Leasehold improvements                      85,115      85,115
                                                   -------   ----------
        Total property and equipment               852,386   1,103,408
        Less accumulated depreciation              670,662     770,048
                                                   -------   ----------
        Property and equipment, net               $181,724   $ 333,360
                                                   =======  ==========

Property and equipment consist of furniture, fixtures, office
equipment, and leasehold improvements 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.

Recoverability of assets is measured by a comparison of the
carrying amount of an asset to future undiscounted net cash flows
expected to be generated by the asset. If such assets are
considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets
exceeds the fair value of the assets.

(d) Patent Rights

Patents are stated at cost (primarily legal fees) and are amortized
using the straight line method over the life of the assets,
generally 10 years.  The Company reviews its patents and trademarks
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. In addition, management's review addresses whether the patent
continues to fit into the Company's strategic business plans.
During the years ended December 31, 1997, 1998 and 1999, the
Company decided not to pursue the technology in certain countries
for strategic reasons and has recorded $300,253, $120,459 and
$58,511 respectively, relating to the expense of writing off these
patents as a charge to research and development.  Accumulated
amortization as of December 31, 1998 and 1999 is $1,305,971 and
$1,377,024 respectively.

<PAGE> 53
(e) Investment in Unconsolidated Affiliates

Investments in unconsolidated affiliates are accounted for
utilizing the equity method of accounting reflecting in the
investment account any initial investment plus the Company's share
of earnings and losses from date of acquisition.  Ribotech, Ltd.
has had net losses since inception and the Company does not share
in those losses in accordance with the licensing agreement defined
in Note 11.  The net investment in Ribotech is zero as of December
31, 1998 and 1999.  Any losses incurred by Ribotech are not
recorded by the Company as the basis is zero and the Company is not
obligated to fund such losses.

(f) Revenue

Revenue is recognized immediately for nonrefundable license fees
when agreement terms require no additional performance with respect
to such on the part of the Company.  Revenue from the sale of
Ampligen under cost recovery clinical treatment protocols approved
by the FDA are recognized when such product is invoiced to the
patient.  Revenue related to the sale of Ampligen were $258,715,
$400,708 and $678,248 for 1997, 1998 and 1999 respectively.

(g) Net Loss Per Share

Basic net loss per share is computed using the weighted average
number of shares of common stock outstanding during the period.
Diluted net loss per share is computed using the weighted average
number of shares of common and diluted potential shares outstanding
during the period. Potential common shares consist of stock options
and warrants using the treasury stock method and are excluded if
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 that will be 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) Sales of Subsidiary Stock

The Company intends to account for any sales of its subsidiaries'
stock as capital transactions. However, as of December 31, 1998 and
1999, the Company owned 100% of each subsidiaries stock.  Any sales
of subsidiary stock to a third party would represent a minority
ownership in the specific subsidiary.

(j) Comprehensive Loss

On January 1, 1998, the Company adopted SFAS No. 130, Reporting
Comprehensive Income. 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 stockholder's equity and comprehensive
loss.  The Statement requires only additional disclosures in the
consolidated financial statements; it does not affect the Company's
financial position or results of operations.  Prior year financial
statements have been reclassified to conform to the requirements of
SFAS No. 130.

Comprehensive loss is summarized below:

                                    1997           1998           1999

                               ============    ===========    ============

(k)            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 amounts
               reported in the financial statements and
               accompanying notes. Actual results could
               differ from those estimates.

(l)            On December 31, 1999, Biovail
               Corporation agreed to purchase 285,714
               shares for $2,250,000.  120,000 of these
               shares were issued from the treasury.
               The remaining 165,714 shares were new
               issuances.  The funds were received on
               February 3, 2000.

(4) Stock-Based Compensation

In 1997, the Company granted 64,597 stock purchase options to
employees with at least one year of service in recognition of
services performed and services to be performed.  For purposes of
proforma disclosure required by Statement of Financial Accounting
Standards No. 123 (SFAS 123") Accounting for Stock-Based
Compensation, the per share weighted average fair value of the
stock purchase warrants granted during 1997 was determined using
the Black-Scholes option pricing model with the following weighted
average assumptions: expected dividend yield of zero, risk free
interest rate ("rate") of 6.14%, volatility 112.25%, and an
expected life of 5 years.  In 1998, the Company granted 1,113,000
warrants to employees in recognition of services performed and
services to be performed.  For purposes of Pro forma Disclosure for
FAS 123 the fair value of the stock purchase warrants granted
during 1998 was also determined using the Black-Scholes option

<PAGE>
<PAGE> 55
pricing model with the rate of 6.14% volatility of 45.67%-73.31%,
and expected lives of 2-5 years.  In 1999, the Company granted
275,000 warrants to employees in recognition of services performed
and services to be performed.  For purposes of Proforma Disclosure
for FAS 123, the fair value of the stock purchase warrants granted
during 1999 was also determined using the Black-Scholes option
pricing model with the rate of 5.81% volatility of 135.4% -
294.31%, and expected life of 2 years.

The Company applies APB Opinion No. 25 in accounting for
stock-based compensation of its employees and, accordingly, no
compensation cost has been recognized for stock purchase warrants
issued to employees in the financial statements. Had the Company
determined compensation cost based on the fair value at the grant
date for its stock-based compensation of its employees the
Company's net loss would have been increased to the pro forma
amount indicated below:

                                    1997          1998         1999
                                    ----          ----          ----
  Net loss      As reported    $(6,106,860)   $(7,324,093)  $(9,201,227)
                Pro forma      $(6,203,259)    (8,199,994)  (10,537,963)

For 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 vesting period of the warrant.

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

(7) Convertible Preferred Stock

In March, 1997, the Company used the services of an investment
banking firm to privately place $5 million of Series E Convertible
Preferred Stock. The proceeds from this placement were used to
retire the  balance of Series D Convertible Stock issued in July of
1996. As an inducement to effect the early redemption of the Series
D Preferred Stock, the Company gave the Preferred Stockholder
200,000 shares of common stock with a guaranteed sales price of $6
per share. As a result of this inducement in 1997,  the Company
incurred a $1.2 million stock conversion cost, which had no effect
on the net equity of the company as it was offset by an

<PAGE>
<PAGE> 59
increase in additional paid-in capital.

The holders of Series E Convertible Preferred Stock shall receive
cumulative dividends when and if declared by the board of directors
at the rate of $60 per share. Holders of Series E Convertible
Preferred Stock upon surrender of the certificates shall have the

declared effective by the SEC. As of December 31, 1998, all holders
of Series E convertible preferred stock had converted their holding

(8) Segment and Related Information

In June 1997, the FASB issued Statement of Financial Standard No.
131, Disclosures about Segments of an Enterprise and Related
Information ("Statement 131"). Statement 131 supersedes Statement
of Financial Standards No. 14, Financial Reporting for Segments of
a Business Enterprise, and establishes new standards for reporting
information about operation segments in annual financial statements
and requires selected information about operating segments in
interim financial reports. Statement 131 also establishes standards
for related disclosures about products and services, geographic
areas and major customers. Statement 131 is effective for periods
beginning after December 15, 1997. This Statement affects reporting
in financial statements only and has no impact on the Company's
results of operations, financial condition or liquidity.

As the Company has one management team in one location performing
research and development activities for Ampligen, no additional
segment disclosure beyond what is reported in the consolidated
financials is necessary under SFAS No. 131.

The following table presents revenues by country based on the
location of the use of the product services.

(9) Research, Consulting and Supply Agreements


The Company has entered into various clinical research agreements
for the purpose of undertaking clinical evaluations of the safety
and efficacy of Ampligen. The Company's obligation under these
agreements is primarily dependent on the number of actual patients
enrolled in the study and may be terminated without penalty at any
time. During the years ending December 31, 1997 and 1998, the
Company incurred approximately $179,000 of research fees under this
agreement with Hahnemann Medical University in Philadelphia. Such
costs were expensed as incurred.  No such costs were incurred in
1999.

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 judgement 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

<PAGE>
<PAGE> 60
a declaratory judgement 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.

In December, 1999, the Company 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 the Company's 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 the
Company's products.  In addition, Biovail agrees to work with the
Company in preparing and filing of a New Drug Submission with
Canadian Regulatory Authorities.  Biovail invested several million
dollars in Hemispherx equity at prices above the then current market
price and agreed to make further payments based on reaching certain
regulatory milestones.  The Agreement requires Biovail to penetrate
certain market segments at specific rates in order to maintain
market exclusivity.

The Company has entered into agreements for consulting services
which are performed at medical research institutions and by medical
and clinical research individuals. The Company's obligation to fund
these agreements can be terminated after the initial funding period,
which generally ranges from one to three years or on an as-needed
monthly basis. During the years ending December 31, 1997, 1998 and
1999, the Company incurred approximately $124,000, $269,000, and
$664,0000, respectively of consulting service fees under these
agreements.  These costs are expenses as incurred.

(10) 401(K) Plan

The Company has a defined contribution plan, entitled the Hemispherx
BioPharma Employees 401(K) Plan and Trust Agreement (the 401(K)
Plan).  All full time employees of the Company 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 the Company at
a rate determined annually by the Board of Directors.

Each participant immediately vests in his or her deferred salary
contributions, while Company contributions will vest over one year.
In 1997, 1998, and 1999, the Company provided matching contributions
to each employee for up to 6% of annual pay of $30,598, $36,958 and
$46,616 respectively.

(11) Royalties, License, and Employment Agreements

The Company also has entered into a licensing agreement with a group
of individuals and Hahnemann University relating to their
contributions to the development of certain compounds, including
Ampligen, and to obtain exclusive information and regulatory rights
relating to these compounds. Under this agreement, the Company will
pay 2% of net sales proceeds of Ampligen not to exceed an aggregate
amount of $6 million per year through 2005.

<PAGE>
<PAGE> 61
As described in Note 9, the Company has agreed to pay royalties
under the Temple Agreement and to its supplier of raw materials.


The Company has contractual agreements with three of its officers.
The contract with one of the officers was terminated in 1999 and a
buy-out amount of $143,000 was paid to this officer.  The aggregate
annual base compensation under these contractual agreements for
1997, 1998, 1999 is $611,678, $622,952 and $815,413 respectively.

receive performance bonuses of up to 25% of the annual base salary
(in addition to the bonuses described below). In 1998, a performance
bonus of $90,397 was granted. In 1997 no performance bonuses were
granted. Pursuant to the employment agreements, certain officers
were granted options under the 1990 Stock Option Plan to purchase
an aggregate of 82,942 shares of the Company's Common Stock at
exercise prices ranging from $2.72-$4.34 and Rule 701 Warrants to
purchase 2,080,000 shares of Common Stock at $3.50 per share. One
of the employment agreements provides for bonuses based on gross
proceeds received by 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
codevelopment of various RNA drugs, including Ampligen, for a period
ending three years from the expiration of the last licensed patents.
The licensing agreement provides 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
territory). In exchange for these marketing and manufacturing
rights, the licensing agreement provides for: (a) a $3 million cash
payment to the Company, all of which was recorded during the year
ended December 31, 1995; (b) the formation and issuance to the
Company of 24.9% of the capital stock of Ribotech, a company which
develops and operates a new manufacturing facility  by
SAB/Bioclones, 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, excluding SAB/Bioclones related sales. In addition,
SAB/Bioclones will have the right of first refusal for oral vaccines
in the licensed territory. In 1996, 1997, 1998 and 1999, the Company
paid Ribotech a total of $581,556 for the purchase and delivery of
polymers.

In October 1994, the Board of Directors granted a director of the
Company the right to receive 3% of gross proceeds of any licensing
fees received by the Company pursuant to the SAB licensing
agreement, a fee of .75% of gross proceeds in the event that SAB
makes a tender offer for all or substantially all of the Company's
assets, including a merger, acquisition or related transaction, and
a fee of 1% on all products manufactured by SAB. The Company may
prepay in full its obligation to provide commissions  within a ten
year period.

In December, 1995, the Company retained the law firm of Akin, Gump,
Strauss, Hauer & Feld, L.L.P. (Akin-Gump) to provide general legal
counsel, advise and representation with respect to various United
States regulatory agencies, primarily the Food and Drug
Administration (FDA). This agreement expired in August, 1997. In
September, 1997, the Company acknowledged a contingent liability of
$147,000 to Akin-Gump for certain fees billed and not covered by the
agreement. These fees are due Akin-Gump if and only if the Company
achieves regulatory approval of Ampligen in the future.

Rent expense charged to operations for the years ended December 31,
1997, 1998 and 1999 amounted to approximately $292,000, $308,000 and
$340,978 respectively.
The term of the lease is through April 30, 2000 with an average rent
of $14,507 per month, plus applicable taxes and charges.

(13) Income Taxes

As of December 31, 1999, the Company has approximately $53,231,000
of federal net operating loss carryforwards (expiring in the years
2003 through 2019) available to offset future federal taxable
income.  The Company also has approximately $5,096,000 of state net
operating loss carryforwards (expiring in the years 2006 through
2009) available to offset future state taxable income.  In addition,
the utilization of the state net operating loss carryforward is
subject to a $2,000,000 annual limitation.

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 ultimate goal 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, 1998 and 1999.

During 1999, the Company amended their prior year tax returns to
capitalize research and development costs to extend the life of the
net operating losses.  The effect of the amended returns is an
increase in the deferred tax asset for research and development and
a decrease in the deferred tax asset for net operating losses at
December 31, 1999.

The components of the net deferred tax asset of December 31, 1998
and 1999 consists of the following:

(14) Contingencies

On September 14, 1998, VMW, Inc. filed a complaint against the
Company in the United States District Court, Southern Division of
New York,  The complaint alleges that the Company failed to fulfill
its financial obligations to VMW, Inc. with respect to a certain
letter agreement pertaining to marketing services rendered.  VMW,
Inc. claims damages of less than $100,000.  The Company
counterclaimed alleging breach of contract by VMW and have demanded
damages of approximately $25,000.  Both parties settled this dispute
in 1998 and executed Mutual Releases.

On September 30, 1998, the Company filed a multi-count complaint
against Manuel P. Asensio, Asensio & Company, Inc., and others in
the United States District Court for the Eastern District of
Pennsylvania.  On October 22, 1998, the Company amended the
complaint to add additional counts and to conform the complaint to
agreed upon dismissals without prejudice as to certain of the
defendants.  On August 13, 1999, the Company amended and
supplemented the complaint for a second time to conform the
complaint to court ordered dismissals of certain counts of the
complaint and parties, to add Asensio.com, Inc. (formerly known as
Asensio Holdings, Inc.), the holding company of defendant Asensio
Company Inc., and to add a conspiracy charge against the remaining
defendants and certain unnamed John Does.

The complaint presently contains claims of defamation,
disparagement, tortious interference with existing and prospective
business relations and conspiracy, arising out of the current
defendants' false and defamatory statements. (The complaint further
alleges that defendants defamed and disparaged the Company in
furtherance of a manipulative, deceptive and unlawful short-selling
scheme between August, 1998, and the present).

On April 19, 1999, defendants Asensio and Asensio & Company, Inc.,
filed an answer and counterclaim against the Company.  The
counterclaim alleges that on or about September, 1998, and in
response to defendants' strong sell recommendation and other press
releases about Hemispherx and its officers and directors, the
Company made defamatory statements about defendants, including that
defendants' attacks and manipulative short-selling scheme may have
constituted criminal wrongdoing on the part of defendants.  The
Company has denied the material allegations of the counterclaim and
is vigorously defending against the counterclaim.  In August, 1999,
several of the short sellers in Hemispherx were indicted by the U.S.
Attorney in New York for money laundering and manipulation in
another non-Hemispherx matter.  The parties are presently engaged
in discovery which is currently scheduled to conclude in the Spring,
2000.

The Company is subject to claims and legal actions that arise in the
ordinary course of their business. Management believes that the
ultimate liability, if any, with respect to these claims and legal
actions will not have a material effect on the financial position
or results of operations of the Company.

(15) 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.  The repurchased shares will eventually be used for
acquisitions or other purposes.  On February 8, 2000, the Board
authorized the repurchase of another 200,000 shares.

(16) Subsequent Events

On March 6, 2000, Cook Imaging Corp. et. al, filed a complaint
against the Company in the United States District Court for the
Eastern District of Pennsylvania.  Cook Imaging Corp. asserts that
the Company refuses to pay for certain Ampligen manufacturing
efforts undertaken by Cook.  The Company plans to respond to the
complaint within the next twenty days.  In essence, the Company
maintains that Cook Imaging Corp. did not perform as required by the
contract under GMP (Good Maintenance Practices) conditions.  The
Company does not believe that Cook Imaging Corp. will prevail in
this matter.
