                                                       September 1, 2005
Dear Stockholders,


The purpose of this letter is to provide an update to our Stockholders regarding
the  status  of the  various  endeavors  that are  currently  being  pursued  by
Hemispherx. We are very excited about where the company stands today.

After  many  years of  clinical  testing,  we are close to  filing  the New Drug
Application  for our  experimental  drug  Ampligen(R)  to treat Chronic  Fatigue
Syndrome.  We feel very secure in the  comprehensiveness  of our data, which has
been compiled from our clinical trials involving over 700 participants.

We are currently  accelerating the implementation of our manufacturing  strategy
for  Ampligen(R).  The  first  part of the  strategy  consists  of  establishing
production of Ampligen(R) raw material,  or polymer,  in our own GMP facility in
New Brunswick, New Jersey, which was acquired in 2003 as part of our transaction
with Interferon  Sciences,  Inc. Creation of this polymer production  capability
has been initiated and we expect to start equipment  validation in New Brunswick
in late September.

The second part of the strategy  involves the formation of a partnership  with a
qualified   contract   manufacturer.   We  have  identified   several   suitable
manufacturing  partners  this  year  and we are  currently  in  the  process  of
selecting  from  the  qualified  candidates.   One  early  candidate  was  Mayne
Pharmaceuticals,   which  had  prior  experience  manufacturing  Ampligen(R)  in
Australia.  Mayne is no longer a viable  candidate since it is in the process of
terminating its contract manufacturing  business. This termination will not have
an effect on our strategy or our timetable.

For the  past 14  years  Ampligen(R)  has  been  successfully  produced  for our
clinical  trials and for use in our Treatment IND program.  The management  team
responsible  for that  manufacturing  remains in place and has been augmented by
the experienced GMP manufacturing team we acquired at the time of the Interferon
Sciences  Inc.  transaction.  We are confident  that our expanded  manufacturing
management  team will enable the  successful  production of  Ampligen(R)  in the
future. We have devoted and, assisted by the twenty million dollar equity credit
facility we recently established,  will continue to devote substantial resources
to our manufacturing process and feel very strongly that it will be completed in
a timely and successful manner.

We are also very exited about the developments  relating to the oral form of our
Alferon N product (Low Dose Oral Interferon  Alfa-N3,  Human Leukocyte Derived),
which is a new delivery form of our FDA approved  drug,  Alferon N. Alferon N is
the  only  natural  interferon  currently  FDA  approved  and  available  in the
marketplace.  We were pleased to announce last quarter that  clinical  trials in
human  volunteers are being conducted in Philadelphia  and that a clinical study
will shortly  commence at the Princess  Margaret  Hospital in Hong Kong.  We are
preparing  more than  300,000  doses of  Alferon  LDO for  appropriate  clinical
programs.  Pending  the  outcome of the  ongoing  clinical  studies and based on
existing  laboratory studies, we expect these trials to demonstrate that Alferon
LDO given orally can activate the relevant immune defense  pathways in the human
body. This would potentially make Alferon LDO the first orally active interferon
drug  candidate  and  would  open an  opportunity  leading  to a wide  range  of
potential new indications.

One such  potential  indication  is Avian Flu.  As widely  covered in the media,
Avian  Flu  is a  devastating  and  contagious  disease.  Health  officials  are
concerned  that Avian Flu could mutate to a highly  contagious  form for humans.
This scenario is considered by experts in the field as highly  probable.  Should
this mutation occur it will be the genesis of the next pandemic and would render
vaccines presently under development ineffective.  The threat of a highly lethal
pandemic has caused  Governments around the world to search for a treatment that
they could potentially stockpile.

In   another    development    Alferon   N   and    Ampligen(R),    experimental
immunotherapeutics,  are among a small  group of  immunotherapeutic  drugs being
considered by the  department  of defense to  potentially  combat  dreaded viral
outbreaks including Avian influenza.  The Department of Defense strategy will be
outlined in an upcoming  article  entitled  "Innate  Immunity for Biodefense:  A
Strategy Whose Time Has Come" proposed for publication in Journal of Allergy and
Clinical  Immunology  (JACI).  This article states that "Ampligen(R) has already
been tested  against  over 25 viruses  and will be used in Advanced  Biosystem's
proposal  for  inhaled  IFN  in  conjunction  with  Alferon...  No  evidence  of
inflammatory  reactions  has been  observed  in either  Ampligen(R)  or Alferon.
Administration  of over  50,000  doses  of  Ampligen(R)  has not  resulted  in a
cell-mediated  autoimmune  response.   Alferon  should  be  superior  to  single
recombinant IFN types with regards to binding to receptors that are structurally
altered by genetic polymorphisms" (emphasis added). This article,  including the
innate immunity strategy for biodefense,  is one of the independent endorsements
of our drug technology that energizes and encourages our present  enthusiasm for
these products.

In closing, with the acceleration of our manufacturing  strategy for Ampligen(R)
and our advancements in the development of the Low Dose Oral Interferon program,
we feel that the company is poised to make considerable progress toward bringing
the Hemispherx products to commercial success.

Sincerely,

/s/ William A. Carter

Hemispherx Biopharma Expands Manufacturing Facility for Production of Ampligen

Status of clinical Trial advancements for Alferon LDO and manufacturing programs
updated in stockholder letter

Philadelphia,  PA, September 1, 2005 - Hemispherx  Biopharma,  Inc. (AMEX:  HEB)
discloses by letter to  stockholders  that it has  increased the capacity of its
facility in New Brunswick, NJ to manufacture its experimental drug, Ampligen(R),
as well as  advancements  in the  application  of Alferon LDO for the  potential
treatment of Avian Flu. The letter,  which is being submitted as an 8-K with the
SEC, highlights several key developments currently underway.

Hemispherx is implementing a three-phase  strategy in its manufacturing  process
of  Ampligen(R).  The  first  component  in  this  process  highlighted  in  the
stockholder  letter is the  establishment  of  production of  Ampligen(R)'s  raw
material polymer in the Company's wholly owned New Brunswick, N.J. manufacturing
facility.  The creation of the polymer production  capability has been initiated
and  Hemispherx  expects to begin  equipment  validation in the facility in late
September.

The second  strategic  component  involves the formation of a partnership with a
qualified contract  manufacturer for finished product.  The company is currently
in  the   process  of   selecting  a   qualified   candidate   from  a  pool  of
already-identified and-pre-qualified contenders.

The third component of the manufacturing strategy is the development of the team
responsible  for the production of  Ampligen(R) in New Brunswick,  N.J.. For the
past 14 years,  Ampligen(R) has been  successfully  produced for clinical trials
and used for an ongoing  Treatment  IND program.  The original  management  team
responsible for that manufacturing remains in tact and has been augmented by the
experienced  GMP  manufacturing  team  that  was  acquired  with  the  Alferon-N
acquisition.

The  developments of the Alferon Low Dose Oral (LDO) trials are also highlighted
in the stockholder  letter.  Clinical trials in human volunteers are underway in
Philadelphia and will also shortly commence at the Princess Margaret Hospital in
Hong Kong.  Accordingly,  there are currently more than 300,000 doses of Alferon
LDO being prepared for these clinical programs.

Pending  the  outcome of the  ongoing  clinical  studies,  and based on existing
laboratory  studies,  Hemispherx expects the trials may demonstrate that Alferon
LDO,  given orally,  can activate the relevant  immune  defense  pathways in the
human body. This development would potentially make Alferon LDO the first orally
active interferon drug candidate and would open an invaluable  opportunity for a
wide range of potential new  indications.  One such potential  indication is for
treating Avian Flu. As widely covered in the media,  Avian Flu is a devastating,
contagious  disease.  Worldwide  health  officials are concerned  that Avian Flu
could mutate to a highly  contagious  form  transferable to humans from animals.
This  scenario  is  considered  by experts  in the field to be highly  probable.
Should this mutation  occur,  it will be the genesis of the next global pandemic
and would render vaccines presently under development ineffective. The threat of
a highly lethal pandemic has caused governments around the world to search for a
treatment that they could potentially stockpile.

Consideration  of Hemispherx's  Alferon and  Ampligen(R)  therapeutics by the US
Department  of  Defense,  in  coordination  with its  Bio-defense  strategy,  is
featured  in an  upcoming  article  in  the  Journal  of  Allergy  and  Clinical
Immunology (JACI) as stated below:

The  Department  of Defense  strategy  will be outlined  in an upcoming  article
entitled  "Innate  Immunity  for  Biodefense:  A  Strategy  Whose Time Has Come"
accepted  for  publication  in the  Journal of Allergy and  Clinical  Immunology
(JACI).  This article states that  "Ampligen(R)  has already been tested against
over 25 viruses and will be used in Advanced  Biosystem's  proposal  for inhaled
IFN in conjunction  with Alferon....  No evidence of inflammatory  reactions has
been observed in either  Ampligen(R) or Alferon.  Administration  of over 50,000
doses of Ampligen(R)  has not resulted in a cell-mediated  autoimmune  response.
Alferon  should be  superior  to single  recombinant  IFN types with  regards to
binding to receptors that are structurally altered by genetic polymorphisms."

HEMISPHERx CEO, Dr. William A. Carter  concluded the stockholder  letter, " With
the  acceleration  of  our  manufacturing   strategy  for  Ampligen(R)  and  our
advancements in the development of the Low Dose Oral Interferon program, we feel
that the company is poised to make  considerable  progress  toward  bringing the
Hemispherx products to commercial success."
