                               PROSPECTUS SUMMARY

     The  following  summary is qualified  in its entirety by the more  detailed
information  and  the  Consolidated   Financial  Statements  and  Notes  thereto
appearing  elsewhere or incorporated by reference  elsewhere in this Prospectus,
including information under "Risk Factors".

                                   THE COMPANY

     Hemispherx Biopharma, Inc. ("Company") is a biopharmaceutical company using
nucleic acid technologies to develop  therapeutic  products for the treatment of
viral diseases and certain cancers. Nucleic acid compounds represent a new class
of  pharmaceutical  products that are designed to act at the molecular level for
the  treatment  of  human  disease.   The  Company's  drug  technology  utilizes
specifically-configured  ribonucleic  acid ("RNA").  One of the Company's double
stranded RNA drug products,  trademarked Ampligen, a parenteral drug product, is
in advanced  human clinical  development  for various  therapeutic  indications.
Based on the results of pre-clinical  studies and clinical  trials,  the Company
believes  that  Ampligen  may have  broad-spectrum  anti-viral  and  anti-cancer
activities.  Over  300  patients  have  received  Ampligen  in  clinical  trials
authorized  by the U.S.  Food and Drug  Administration  ("FDA")  at over  twenty
clinical trial sites across the United States,  representing the  administration
of more than 40,000 doses of this drug.  Sales on a pre-approval,  cost recovery
basis have been initiated in Belgium,  Canada and the United States. The Company
is presently  exploring  additional  distributor  relationships for Europe,  the
United  States  and  Asia  to  set  the  stage  for  wider  market  penetration.
SAB/Bioclones,  the Company's partner in certain countries, is initiating trials
of Ampligen in South Africa and Australia.

     Ampligen is being developed clinically for use in treating three anti-viral
indications:  chronic  hepatitis B virus ("HBV")  infection (Phase I/II clinical
trial),  human  immunodeficiency  virus ("HIV") associated disorders (Phase II),
and myalgic encephalomyelitis,  also know as chronic fatigue syndrome ("ME/CFS")
(Phase II/III).  The Company's  business strategy is designed around seeking the
required regulatory  approvals which will allow the progressive  introduction of
Ampligen  for HIV and ME/CFS  followed  by HBV in the U.S.,  Canada,  Europe and
Japan.  Ampligen has also received Orphan Drug designation from the FDA for four
indications (AIDS,  renal cell carcinoma,  chronic fatigue syndrome and invasive
malignant melanoma). The Company is also developing a second generation RNA drug
technology,  termed  Oragen  compounds,  which the Company  believes  offers the
potential for broad spectrum antiviral activity by oral administration.

     The  World   Health   Organization   ("WHO")   estimates   that  there  are
approximately  300 million chronic  carriers of HBV worldwide.  More than 40% of
the  persistently  infected  persons  who  survive  to  adulthood  will die from
cirrhosis,  liver cancer, or some other  consequence of their infection.  In the
U.S. alone, there are an estimated 1.25 million carriers.  HBV is one of several
viruses that cause human  hepatitis,  or inflammation of the liver.  The Company
has been  conducting a Phase I/II clinical trial of Ampligen in the U.S. for the
treatment of chronic HBV infection at Stanford  University and the University of
Pennsylvania.  A significant  reduction in 


                                       5
<PAGE>

viral  components and  improvement in liver function was noted during the course
of the Phase I/II clinical  trial to date and the drug has been  generally  well
tolerated.  At present,  interferon-alpha  is the only approved  product for the
treatment  of this  disease;  however,  60% to 75% of patients  with chronic HBV
ultimately fail to respond to  interferon-alpha.  The global sales of interferon
are  presently  estimated at more than $1 billion,  largely for its use in liver
infections.

     The Centers for Disease  Control  ("CDC") has estimated that  approximately
one million  people in the U.S. are infected  with HIV,  excluding  patients who
have progressed to fully  symptomatic  AIDS. The WHO has estimated that 30 to 40
million people will be infected with HIV worldwide by the year 2000. The Company
is currently  conducting  a Phase II clinical  trial of Ampligen in the U.S. for
the treatment of HIV infection.  The drug  technology is designed to enhance the
patient's  own immune  system,  thereby  fighting the invasive  viral agent more
effectively and resulting in more durable long term benefits.

     ME/CFS is a condition  recently  recognized by the CDC and characterized by
unexplained  fatigue  or chronic  illness  for six months or longer for which no
cause has been identified after a thorough medical work-up.  Although the CDC is
presently  conducting studies to more exactly determine the rate of incidence of
ME/CFS,  the CDC's latest estimate of the prevalence rate of this disease in the
U.S. is in excess of 500,000  cases.  The Company has entered  into an agreement
with a Canadian  pharmaceutical firm pursuant to which the Canadian company will
provide various  services in connection  with the  distribution of Ampligen on a
cost recovery  basis as  authorized  under the Canadian  emergency  drug release
program.  Presently the Company is receiving  revenues from sales of Ampligen to
patients in an open label clinical trial being conducted in Belgium. The Company
is currently  discussing  open-label and placebo controlled trials with the FDA.
The  Company is unaware of any other new drugs which are under  development  for
treatment of ME/CFS.  Today, ME/CFS accounts for a significant portion of people
entering chronic  disability  status,  especially in the western U.S. Thus, this
presently  untreatable  illness  constitutes a significant impact on the overall
cost of health care.

         The Company also has clinical experience with Ampligen in patients with
certain cancers,  including renal cell carcinoma  (kidney cancer) and metastatic
malignant melanoma.  Based on estimates prepared by the American Cancer Society,
the Company believes that approximately 25,000 new cases of renal cell carcinoma
will be diagnosed in the U.S. each year.  The Company was authorized by the FDA,
in the U.S., and the HPB, in Canada,  to initiate a Phase II/III  clinical trial
of Ampligen in renal cell carcinoma patients. The HPB has authorized the Company
to charge  patients  for the cost of the  Ampligen  administered  to renal  cell
patients in the context of clinical trials.  Based on estimates  prepared by the
American  Cancer Society,  the Company  believes that  approximately  34,000 new
cases of malignant  melanoma will be diagnosed in the U.S. each year.  Data from
the American Cancer Society and the World Health Organization indicate that both
the incidence and mortality  from malignant  melanoma are rising  steadily among
white  populations  throughout the world.  In the past decade,  the incidence of
melanoma has  increased  faster than that of any other cancer except lung cancer
in women.

     On May 1, 1997,  the Company  received  permission  from the FDA to recover
costs  from  ME/CFS  patients  in the  Company's  AMP-511  open-label  treatment
protocol.  In June 1997,  five (5) clinical  sites across the United  States had
been  approved  to  participate  in this  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.  This treatment protocol has begun to
enroll  ME/CFS  patients  at these  centers in the U.S.  The Company has been in
discussion  with the FDA on the design of a  controlled  ME/CFS  clinical  trial
(AMP-516).

     In November 1995, the Company sold 5,313,000 Units at $3.50 per Unit in its
initial public offering. Each Unit consists of one share of Common Stock and one
Class A Warrant.

     In October  1994,  the Company  entered  into an agreement  with  Bioclones
Proprietary  Limited  ("Bioclones"),   a  biopharmaceutical   company  which  is
associated with The South African  Breweries  Limited ("SAB" and,  together with
Bioclones,  "SAB/Bioclones") with respect to codevelopment of various RNA drugs,
including Ampligen,  for which the Company has previously obtained international
patent  protection.  The licensing  agreement,  as amended (the "SAB Agreement")
provides  that  the  Company  will  provide   SAB/Bioclones  with  an  exclusive
manufacturing  and marketing license for certain Southern  hemisphere  countries
(including  certain  countries in South America) as well as the United  Kingdom,
Ireland,  Africa,  Australia,  Tasmania, New Zealand and certain other countries
and territories.  In exchange for these marketing and distribution  rights,  the
SAB  Agreement  provides  for:  (a) a $3 million  cash  payment to the  Company,
payable in installments upon the occurrence of certain milestones, including the
transfer of certain technical documents which have already been transferred; (b)
the  formation  and  issuance to the Company of 24.9% of the capital  stock of a
company which is developing and operating a new  manufacturing  facility for RNA
drugs  constructed  by  SAB/Bioclones;  and (c)  royalties  on all  sales of the
Company's  product in the  licensed  territories  after the first $50 million of
sales. In addition, SAB/Bioclones has agreed to use reasonable efforts to pursue
the marketing  approval of Ampligen for hepatitis B in Australia,  South Africa,
Brazil,  and the United  Kingdom,  as well as to perform (at its own  expense) a
phase III study of Ampligen  for chronic HBV  infection in South  Africa,  which
clinical  study is to be performed  pursuant to U.S. FDA good clinical  practice
and good laboratory  practice  ("GLP")  guidelines and standards.  SAB/Bioclones
will be  granted  a right of first  refusal  to  manufacture  and  supply to the
Company the drug product  required for not less than one-third of its world-wide
sales of Ampligen (after deducting  SAB/Bioclones-related sales). As of December
31, 1997, the Company has received approximately  $3,000,000 pursuant to the SAB
Agreement.

     In  September  1994,  the Company  formed  three  subsidiaries  and granted
licenses to the  subsidiaries  for the purpose of developing  its technology for
ultimate sale into certain  non-pharmaceutical  specialty consumer markets, such
as the  tobacco  market,  the market for  skincare  products  and the market for
diagnostic  devices.  The  Company  intends  to  issue  equity  in one  of  such
subsidiaries  and has granted  options to certain of its officers and directors.
No assurance can be given that any of these  companies  will be able to complete
testing in these areas,  develop any products or successfully produce and market
any products in the targeted specialty consumer markets.

                               RECENT DEVELOPMENTS

     In October 1997,  the Company  raised an aggregate of  $10,005,000 in gross
proceeds through two private offerings to "accredited  investors",  as that term
is defined in Rule 501 of the  Securities  Act,  pursuant to Regulation D of the
Securities  Act and  Rule  506  promulgated  thereunder.  The  terms  of the two
offerings are as follows:

          1.  Pursuant to the Term Sheet dated  September  2, 1997,  the Company
     sold 2,840,000 shares of Common Stock at $2.50 per share, through Hermitage
     Capital, Inc., the Company's placement agent ("Hermitage"), thereby raising
     $7,100,000.  Hermitage  received as compensation,  6% of the gross proceeds
     and  200,000  warrants  exercisable  at $4.00  per share  and  expiring  on
     December 31, 2000. The shares of Common Stock and the shares underlying the
     warrants are subject to 12 month lock-up agreements.

          2. Pursuant to the Term Sheet dated  September  22, 1997,  the Company
     sold 968,334 shares of Common Stock at $3.00 per share, and one warrant for
     every ten shares purchased. The warrants are exercisable at $4.00 per share
     and expire on December 31, 2000. The Company offered its securities through
     finders and  broker/dealers,  and paid  commissions of 6% on sales, and one
     warrant for every ten shares sold. The Company raised $2,905,000 and issued
     96,833  warrants  to  various  investors  and  88,234  warrants  to various
     finders.

     In March 1997,  the Company  sold 5,000 shares of E Preferred at $1,000 per
share in a private transaction pursuant to Regulation D of the Securities Act of
1933, as amended  ("Securities  Act") and Rule 506 promulgated  thereunder.  The
proceeds from such offering  were used to retire all  outstanding  shares of the
Company's Series D Preferred Stock.

     In July 1996, the Company sold 6,000 shares of Series D Preferred  Stock at
$1,000  per share in a  private  transaction  pursuant  to  Regulation  D of the
Securities  Act  and  Rule  506  promulgated  thereunder.  The  Company  filed a
registration  statement  on  Form  S-1,  which  was  declared  effective  by the
Commission on September 16, 1996,  registering  2,427,275 shares of Common Stock
underlying the Series D Preferred  Stock and 890,543 Shares  underlying  certain
other warrants and options.

     The Company's  corporate  headquarters  are located at 1617 JFK  Boulevard,
Philadelphia,  Pennsylvania  19103.  The  Company's  telephone  number  is (215)
988-0080.

                                  RISK FACTORS

     AN  INVESTMENT  IN THE  SECURITIES  OFFERED  HEREBY IS HIGHLY  SPECULATIVE,
INVOLVES  A HIGH  DEGREE OF RISK AND  SHOULD BE MADE ONLY BY  INVESTORS  WHO CAN
AFFORD THE LOSS OF THEIR ENTIRE  INVESTMENT.  PROSPECTIVE  PURCHASERS,  PRIOR TO
MAKING AN  INVESTMENT  DECISION,  SHOULD  CAREFULLY  CONSIDER,  ALONG WITH OTHER
MATTERS REFERRED TO HEREIN, THE FOLLOWING RISK FACTORS:

1.  Dependence  on Ampligen;  Non-Exclusive  Right to  Manufacture  of Ampligen;
Expiration of Patents.

     The  Company's  principal  development  efforts  are  currently  focused on
Ampligen. While most clinical trials of Ampligen have to date produced favorable
results,  additional  trials  sponsored  by  the  Company  are  planned,  and no
assurance can be given that the drug will  ultimately be demonstrated to be safe
or  efficacious.  In addition,  while  Ampligen has been  authorized  for use in
clinical  trials in the United States and other  countries,  no assurance can be
given that additional clinical trials approvals will be authorized in the United
States or in other countries in a timely fashion or at all or that such clinical
trials will be  completed  by the  Company.  The Company has never  commercially
introduced a product,  and no assurance can be given that  commercialization  of
Ampligen in any countries where Ampligen may be approved will prove  successful.
In addition, the Company does not have exclusive rights to manufacture Ampligen.
Competitors  of the Company are  currently  able to  manufacture  Ampligen.  The
Company  believes,  however,  that its  extensive  patent estate may hinder such
competitors  from testing and  developing  Ampligen for  particular  indications
since the Company has patented the use of Ampligen for many disease indications.
The Company further believes that the available market for non-patented  disease
indications  for Ampligen  which might be available  to  competitors  is minimal
since the Company believes,  based on laboratory tests, that Ampligen may not be
effective against such disease indications; however, no assurances can be given.
Willful  infringement of the Company's  patents by a competitor  could result in
significant  monetary damages to the Company in the event that such infringement
was not  enjoined  by a court  of  law.  Nevertheless,  in the  event  that  the
Company's   patent   protection  is  not  adequate  for  all  relevant   disease
indications,  competitors  might  be able to  test,  develop  and  commercialize
Ampligen. Additionally, as a result of the Company's dependence on Ampligen, the
failure to  demonstrate  the  drug's  safety and  efficacy  in planned  clinical
trials, to conduct the planned clinical trials,  to obtain additional  approvals
for the drug or to successfully  commercialize  the drug would have a materially
adverse effect on the Company.

2. No Assurance of Regulatory Approval; Government Regulation.

     The Company's research,  preclinical development,  clinical trials, and the
manufacturing and marketing of its products are subject to extensive  regulation
by numerous governmental authorities in the U.S. and other countries, including,
but not limited to, the Food and Drug Administration ("FDA") in the U.S. and the
Health Protection Branch of Canada's Department 


                                       9
<PAGE>

of Health and Welfare ("HPB"),  a federal  regulatory agency in Canada.  None of
the Company's products has been approved for commercial sale by the FDA, the HPB
or any other  foreign  regulatory  authority  and the Company does not expect to
achieve  profitable  operations  unless  Ampligen  receives  FDA approval and is
commercialized  successfully.  In order to  obtain  FDA  approval  of a new drug
product for an indication,  the Company must  demonstrate to the satisfaction of
the FDA that such product is safe and  effective  for its intended uses and that
the Company is capable of manufacturing the product to the applicable regulatory
standards.  The process of obtaining FDA and other required regulatory approvals
(including  those of the HPB) is rigorous  and lengthy and has required and will
continue to require the  expenditure of substantial  resources.  There can be no
assurance  that the  Company  will be able to obtain  the  necessary  regulatory
approvals.  Unsatisfactory clinical trial results, clinical trials not conducted
in accordance with applicable  protocol  requirements and/or delays in obtaining
regulatory  approvals  would prevent the marketing of products  developed by the
Company, and pending the receipt of such approvals, the Company will not receive
product revenues or royalties.

     Pharmaceutical  products  and their  manufacture  are subject to  continued
review following regulatory approval,  and later discovery of previously unknown
problems may result in the imposition of  restrictions on such products or their
manufacture,  including  withdrawal of the products from the market.  Failure to
comply with applicable regulatory requirements could, among other things, result
in  fines,  suspension  of  regulatory  approvals,  operating  restrictions  and
criminal prosecution.  The Company cannot predict the extent to which current or
future  government  regulations  might have a materially  adverse  effect on the
production,  marketing and sale of the Company's products.  Such regulations may
delay or prevent clinical trials,  regulatory  approval,  and the manufacture or
marketing of the Company's potential products. In addition,  such regulation may
impose costly procedures upon the Company's  activities or furnish a competitive
advantage to other  companies more  experienced  in regulatory  affairs than the
Company and may deplete the Company's liquidity and capital resources.

3. Additional Financing Requirements.

     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.  Based on its current operating plan, the
Company  anticipates  that  projected  cash flow from  operations  and currently
available  financing  arrangements  will be  sufficient  to meet  the  Company's
capital  requirements  for  approximately  24  months  from  the  date  of  this
Prospectus.  It is not  expected  that the  Company's  current cash flow will be
sufficient  to enable the Company to complete the necessary  clinical  trials or
regulatory  approval  process for  Ampligen for any  indication  or, if any such
approval  were  obtained,  to begin  manufacturing  or  marketing  Ampligen on a
commercial  basis.  Accordingly,  the  Company  may  need to  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  


                                       10
<PAGE>

available from  operations  and if the Company is not able to secure  additional
sources of  financing on  acceptable  terms,  the  Company's  business  could be
materially adversely affected.

     Moreover,  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. There
can be no assurance that any additional funding will be available to the Company
on terms acceptable to the Company, if at all. 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  as to  which  cost  recovery  from
participants has been approved.

4. Uncertainty Regarding Patents and Proprietary Rights.

     The Company's  success will depend, in large part, on its ability to obtain
patent  protection  for its  products  and to obtain  and  preserve  proprietary
information and trade secrets. The Company does not have exclusive rights to the
manufacture of Ampligen. Consequently, the Company's ability to obtain exclusive
rights  for  the  commercial  sale  of  Ampligen  is  subject  to the  Company's
acquisition of enforceable patents covering the use of the drug for a particular
indication.  The Company has been issued certain  patents on the use of Ampligen
alone and Ampligen in combination  with certain other drugs for the treatment of
human  immunodeficiency virus ("HIV"). The Company has also been issued a patent
on the use of Ampligen in combination with certain other drugs for the treatment
of chronic hepatitis B virus ("HBV") and chronic hepatitis C virus ("HCV") and a
patent which affords  protection on the use of Ampligen in patients with myalgic
encephalomyetis,  also know as chronic fatigue syndrome ("ME/CFS"). To date, the
Company has not been  issued any patents in the U.S.  for the use of Ampligen as
monotherapy  for HBV or for any of the  cancers  which the Company has sought to
target.  The Company's  applications for U.S. patents for the use of Ampligen as
monotherapy for HBV and in the treatment of renal cell carcinoma and lung cancer
are  currently  pending,  although no  assurances  can be given that any of such
applications will be approved.  No assurances can be given that 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
the Company.  The Company believes that the existence of the Company's treatment
indication  patents  precludes a competitor from selling an identical or similar
product for the same treatment  indication without infringing upon the Company's
issued patents.  No assurance can be given,  however,  that the Company's patent
protection  will be adequate to prevent the entry into the market of competitors
for all of the Company's treatment indications.

     The Company has been unable to secure Orphan Drug  designation from the FDA
for  treatment of HBV in the U.S. due to the wide  incidence of the disease.  In
the event that the 


                                       11
<PAGE>

Company is unable to obtain  adequate patent  protection for the indication,  it
would  be  unable  to  maintain  a   competitive   advantage   over  other  drug
manufacturers which could enter the market immediately.

     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. Accordingly, there can be no assurance
that patent  applications  relating to the Company's 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 other intellectual property rights and that such litigation
could consume  substantial  resources of the Company.  No assurance can be given
that the Company's patents will provide competitive  advantages for its products
or will not be successfully  challenged or circumvented by its  competitors.  No
assurance  can be given that  patents  do not exist or could not be filed  which
would have a materially  adverse  effect on the Company's  ability to market its
products  or to obtain or  maintain  any  competitive  position  the Company may
achieve with respect to its products. The Company's patents also may not prevent
others from  developing  competitive  products using related  technology.  Other
companies obtaining patents covering products or processes useful to the Company
may bring  infringement  actions against the Company.  There can be no assurance
that the Company will have the financial  resources  necessary to enforce patent
rights it may hold. As a result,  the Company may be required to obtain licenses
from  others to develop,  manufacture  or market its  products.  There can be no
assurance  that  the  Company  would be able to  obtain  any  such  licenses  on
commercially  reasonable  terms, if at all. The Company licenses certain patents
and  proprietary  information  from third  parties,  some of which  patents  and
proprietary  information  may have been developed with  government  grants under
circumstances where the government maintained certain rights with respect to the
patents/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 the
Company's  license.  Certain of the  Company's  know-how and  technology  is not
patentable,  particularly  the procedures  for the  manufacture of the Company's
drug product  which are carried out  according to standard  operating  procedure
manuals.  To protect its rights,  the Company has since 1991 required  employees
and consultants to enter into confidentiality agreements with the Company. There
can be no assurance that these agreements will not be breached, that the Company
would have adequate and enforceable  remedies for any breach,  or that any trade
secrets of the  Company  will not  otherwise  become  known or be  independently
developed by competitors.

5. Disputes and Legal Proceedings Related to Patent Rights.

     The  Company's  ownership of one of its patents for the use of Ampligen for
the  treatment  of HIV is the subject of a dispute.  Vanderbilt  University  has
advised the Company of its position that  employees of the  University  were the
inventors of the patent at issue.  The Company does not believe the University's
position to have merit, and if the University filed a claim against 


                                       12
<PAGE>

the Company, the Company would vigorously defend against such an action. If such
a claim were filed and if such a claim were found to have merit, the loss of the
patent at issue would not have a materially adverse effect on the Company's long
range business  since the University  would be able to limit or prevent only the
Company's  use of Ampligen in  combination  with AZT in the treatment of HIV. In
the event that the University  obtained  ownership of the disputed  patent,  the
University  could  license  a third  entity  to  sell  Ampligen  for a  specific
combinational  treatment.  However,  without the Company's consent,  the Company
believes  that the  commercialization  process by a third  party  would  require
substantial   expenditure  to  repeat   clinical  trials  and  establish  a  new
manufacturing  protocol  acceptable to  regulatory  agencies and would require a
license  from  the  Company  for  the  use of  Ampligen  as a  component  of the
combinational requirement. Furthermore, the loss of this patent would not affect
the  Company's  ability  to  market  Ampligen  as a  monotherapy  for HIV  which
treatment the Company has tested and expects to continue to develop.

6. History of Losses; Future Profitability Uncertain.

     The Company began  operations in 1966 and has reported net profit only from
1985 through 1987.  Since 1987, the Company has incurred  substantial  operating
losses and as of  December  31,  1996,  the  Company's  accumulated  deficit was
approximately $48 million.  The Company has not generated  significant  revenues
from its products and could incur substantial and increased losses over the next
several years. Such losses may fluctuate  significantly from quarter to quarter.
There  can be no  assurance  that the  Company  will  ever  achieve  significant
revenues  from product  sales or become  profitable.  The  Company's  ability to
achieve  profitable  operations  is dependent,  in large part,  on  successfully
developing  products,  obtaining  regulatory  approvals on a timely  basis,  and
making the transition  from a research and  development  firm to an organization
producing commercial products or entering into joint ventures or other licensing
arrangements.  No assurance can be given that the Company's product  development
efforts will be successfully  completed,  required regulatory  approvals will be
obtained,  any  products  will be  manufactured  and marketed  successfully,  or
profitability will be achieved.

7. 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.  The Company's
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. Ampligen
is not expected to be generally available for commercial sale for any indication
for at  least  the  next  several  years,  if at  all.  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  


                                       13
<PAGE>

of  commercial  quantities  of the  Company's  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 the Company's  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.

8. Manufacturing Experience and Capacity.

     Ampligen is currently  produced only in limited  quantities  for use in its
clinical trials, however, the Company is engaged with its partner, Bioclones (as
defined  below) and other  suppliers  to  increase  production  capacity.  To be
successful, the Company's products must be manufactured in commercial quantities
in compliance with regulatory requirements and at acceptable costs. Although the
Company  has  entered  into  an  agreement  with  Bioclones  Proprietary,   Ltd.
("Bioclones"),  a  biopharmaceutical  company  which is  associated  with  South
African Breweries,  Ltd.  (together with Bioclones,  "SAB")(the "SAB Agreement")
which provides for the construction of a new commercial  manufacturing  facility
by a company  which is 24.9% owned by the Company,  no assurance can be given as
to the timing of such construction, and therefore the Company may continue to be
dependent on third  parties for a portion of the  manufacturing  and  production
process.  A pilot  facility  in South  Africa is being  expanded  to  provide an
increased  supply of Ampligen  raw  material.  While the Company  believes  that
construction of the commercial  facility will begin in 1998, the construction is
dependent upon the regulatory status of Ampligen in various global markets,  and
no assurance can be given with respect to when, and if, construction will occur.
The  Company  intends to  utilize  third-party  facilities  if and when the need
arises  or,  if it is  unable  to do so,  to build or  acquire  commercial-scale
manufacturing  facilities.  The  Company  will  need to comply  with  regulatory
requirements for such facilities,  including those of the FDA and HPB pertaining
to Good Manufacturing  Practices ("GMP") 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
the Company's long-term needs.  Moreover,  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  manufacture  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, can, among other things, require
new  clinical  studies  and affect  orphan  drug  status,  particularly,  market
exclusivity rights, if any, under the Orphan Drug Act.

9. Marketing Experience and Capacity.

     The Company  currently has limited  marketing or sales  capability and does
not expect to establish a significant  direct sales  capability for at least the
next several years. To the extent that the Company determines not, or is unable,
to enter into marketing  agreements or third party  distribution  agreements for
its products,  significant  additional  resources  will be required to develop a
sales force and distribution  organization.  Pursuant to the SAB Agreement,  the


                                       14
<PAGE>

corporate  partner will be  responsible  for fielding an adequate sales force in
South America, Africa, United Kingdom, Australia and New Zealand.  Nevertheless,
there  can be no  assurance  that the  Company  will be able to  establish  such
arrangements,  under the SAB Agreement or otherwise,  on terms acceptable to the
Company,  if at all, or that the cost of establishing such arrangements will not
exceed any product revenues,  or that such  arrangements will be successful.  To
the  extent  that the  Company  enters  into  co-marketing  or  other  licensing
arrangements,  any  revenues  received by the Company  will be  dependent on the
efforts of third  parties,  and there can be no assurance that such efforts will
be successful.

10. Rapid Technological Change and Substantial Competition.

     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 the Company,  as well as  substantial  marketing,  financial and managerial
resources,  and represent significant  competition for the Company.  Acquisition
of, or investments in,  competing  companies by large  pharmaceutical  companies
could increase such competitors' financial, marketing and other resources. There
can be no assurance  that  developments  by others will not render the Company's
products or technologies  obsolete or noncompetitive or that the Company will be
able to keep pace with technological developments. 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 the Company.  These  competing  products may be more
effective and less costly than the Company's products. In addition, conventional
drug therapy,  surgery and other more familiar treatments will offer competition
to the Company's products.  Furthermore,  many of the Company's competitors have
significantly  greater  experience than the Company in pre-clinical  testing and
human clinical trials of  pharmaceutical  products and in obtaining FDA, HPB and
other regulatory approvals of products.  Accordingly,  the Company's competitors
may succeed in  obtaining  FDA and HPB product  approvals  more rapidly than the
Company.  If any of the Company's products receive regulatory  approvals for any
indication and the Company commences  commercial sales of its products,  it will
also be  competing  with  respect  to  manufacturing  efficiency  and  marketing
capabilities,   areas  in  which  it  has  limited  experience.   The  Company's
competitors  may  possess  or obtain  patent  protection  or other  intellectual
property rights that prevent,  limit or otherwise adversely affect the Company's
ability to develop or exploit its products.

11. Dependence upon Qualified and Key Personnel.

     Because of the specialized nature of the Company's business,  the Company's
success will depend,  among other  things,  on its ability to attract and retain
qualified management and scientific personnel. Competition for such personnel is
intense.  There can be no assurance that the Company will be able to continue to
attract or retain such persons.  The Company currently 


                                       15
<PAGE>

depends  upon the  services  of Dr.  William A.  Carter,  its  President,  Chief
Executive  Officer and  Chairman  of the Board,  Robert E.  Peterson,  its Chief
Financial   Officer  and  Dr.  Carol  A.  Smith,   the  Company's   Director  of
Manufacturing  and Process  Development.  Certain key individuals  upon whom the
Company  currently  depends,  including but not limited to the Company's Medical
Director,  Dr. David Strayer,  are not employees of the Company, but instead are
employees of an institution  with whom the Company has a  collaborative  at will
arrangement. In addition, Dr. Smith does not have a written employment agreement
with the Company.  The continued  availability to the Company of the services of
these  individuals is subject to the policies of the  institution  which employs
them;  any change in such policies may have an adverse effect upon the Company's
continued retention of the services of these individuals.  While the Company has
an employment agreement with Dr. William A. Carter, and has 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  or of  the  services  of  such  employees  of
collaborators  or the failure to recruit  additional  personnel  as needed could
have a  materially  adverse  effect on the  Company's  ability  to  achieve  its
objectives.

12. Dependence on Third Parties.

     The Company's strategy for research,  development and  commercialization is
to  rely  in  part  upon  collaborative   arrangements  with  third  parties  in
appropriate  circumstances.  The  Company's  strategy  has led it to enter  into
various arrangements with universities,  research groups,  licensors and others.
The  Company  is  dependent  on a number of  important  arrangements  with third
parties.  In particular,  the Company  utilizes the services of employees of and
regularly makes use of certain equipment and facilities at Allegheny  University
and has obtained certain of its technology for Oragen products through a license
with Temple University.  There can be no assurance that the Company will be able
to  negotiate  additional  third party  arrangements  or continue  any  existing
arrangements  on  terms  acceptable  to the  Company,  if at all,  or  that  key
researchers  upon whom the Company is dependent  will  continue to be associated
with such universities and/or to work on the Company's products. The loss of any
such existing  arrangement  or key  researcher  could have a materially  adverse
effect on the Company.  The Company may seek a significant portion of its future
capital  requirements from arrangements with pharmaceutical  companies or others
pursuant to  arrangements  under which,  among other  things,  the Company would
receive payment for certain research and development  activities in exchange for
future royalty  payments.  There can be no assurance that any such  arrangements
will be  established  on a basis  acceptable  to the  Company,  if at all, or if
established,  will be scientifically or commercially successful.  The failure to
achieve such arrangements on satisfactory  terms could have a materially adverse
effect on the  Company.  The  Company is  dependent  upon  certain  third  party
suppliers for key components of its proposed  products and for substantially all
of the production process. The failure to continue  arrangements with such third
parties or obtain satisfactory  substitute  arrangements could have a materially
adverse effect on the Company.


                                       16

13.  Impact  of  Potential  AMEX  Delisting  on   Marketability  of  Securities;
Broker-Dealer Sales of the Company's Securities.

     The  Company's  Common Stock and Class A Warrants  trade on AMEX.  AMEX has
rules which establish  criteria for the continued listing of securities on AMEX.
Generally,  AMEX will consider delisting or suspending a company based on, among
other things, the following criteria:  stockholders'  equity,  operating losses,
reduced market value of publicly held shares, substantial disposition of assets,
and total number of shareholders.

     If the  Company  were to continue to incur  operating  losses,  it might be
unable to maintain the standards for continued listing and the listed securities
could be subject  to  delisting  from  AMEX.  If the  Company's  securities  are
delisted,  an investor  would find it more difficult to dispose of the Company's
securities  or to obtain  accurate  quotations  as to the price of the Company's
securities  and it  could  have  an  adverse  effect  on the  coverage  of  news
concerning the Company. In addition,  if the Company's securities were delisted,
they would likely be subject to a rule that imposes  additional  sales  practice
requirements  on  broker-dealers  who sell such securities to persons other than
established   customers  and  accredited  investors  (accredited  investors  are
generally  persons  having net worth in excess of  $1,000,000  or annual  income
exceeding  $200,000,  or  $300,000  together  with a spouse).  For  transactions
covered  by  this  rule,  the  broker-dealer  must  make a  special  suitability
determination  for the purchaser and must have received the purchaser's  written
consent  to the  transaction  prior  to  sale,  as  well as  disclosing  certain
information  concerning  the risks of  purchasing  low-priced  securities on the
market for such  securities.  Consequently,  delisting,  if it  occurred,  would
adversely affect the ability of broker-dealers to sell the Company's  securities
and would make subsequent financing more difficult.

14. Product Liability Exposure.

     The  Company  faces  an  inherent  business  risk of  exposure  to  product
liability  claims in the event that the use of its  products  results in adverse
effects.  Such  liability  might  result from claims made  directly by patients,
hospitals,  clinics or other consumers, or by pharmaceutical companies or others
manufacturing  such  products on behalf of the  Company.  While the Company will
continue to attempt to take appropriate  precautions,  there can be no assurance
that it will avoid significant product liability exposure. The Company currently
maintain worldwide product liability insurance coverage.

15. Uncertainty of Health Care Reimbursement and Potential Legislation.

     The  Company's  ability to  successfully  commercialize  its 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 


                                       17
<PAGE>

pharmaceutical  products.  The Company cannot predict what, if any,  legislation
will  ultimately  be adopted or the impact of such  legislation  on the Company.
Reimbursement from government agencies may become more restricted in the future.
The Company also  understands  that there is  increasing  political  pressure in
Canada  to  limit  health  care  costs;  no  assurances  can be  given  that the
legislative  or  regulatory  results,  if any, of such pressure will not have an
adverse impact on the Company. Furthermore, there can be no assurance that third
party insurance  companies will allow the Company to charge and receive payments
for its products  sufficient to realize an appropriate  return on its investment
in product development. The Company's potential products represent a new mode of
therapy,  and the Company expects that the costs  associated with purchasing and
administering  its products will be substantial.  There can be no assurance that
the Company's 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 payors' reimbursement will not
adversely  affect the  Company's  ability to sell its  products on a  profitable
basis.

16. Hazardous Materials.

     The Company's business involves the controlled use of hazardous  materials,
carcinogenic chemicals and various radioactive  compounds.  Although the Company
believes that its 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,  the Company 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.  The Company is
also  subject  to a variety of laws and  regulations  relating  to  occupational
health and safety,  environmental  protection,  hazardous substance control, and
waste  management  and  disposal.  The  failure  to  comply  with  any  of  such
regulations could subject the Company to, among other things, third party damage
claims, civil penalties and criminal liability.

17. Possible Volatility of Stock Price.

     The stock market in general and biotechnology and pharmaceutical  stocks in
particular  have  from time to time  experienced  significant  price and  volume
fluctuations  that may be unrelated to the operating  performance  of particular
companies.  The market  price of the Common Stock and  Warrants,  like the stock
prices  of  many  publicly  traded  biotechnology  and  smaller   pharmaceutical
companies, may be highly volatile.  Announcements of technological  innovations,
regulatory matters or new commercial products by the Company or its competitors,
developments  or disputes  concerning  patent or proprietary  rights,  publicity
regarding  actual or  potential  medical  results  relating  to  products  under
development by the Company or its competitors,  regulatory  developments in both
the  U.S.  and  foreign   countries,   public   concern  as  to  the  safety  of
pharmaceutical   products,    economic   and   other   external   factors,   and
period-to-period  fluctuations  in  financial  results,  may have a  significant
impact on the market price of the Common Stock and Warrants.

18. Shares Eligible for Future Sale; Registration Rights.

     A  substantial  amount  of  the  Company's  outstanding  Common  Stock  are
restricted securities, as that term is defined in Rule 144 promulgated under the
Securities Act ("Rule 144"). Absent registration under the Securities Act or the
availability  of an exemption  under the Securities Act, the sale of such shares
is subject to Rule 144. In general,  under Rule 144, subject to the satisfaction
of certain other  conditions,  a person,  including an affiliate of the Company,
who has beneficially  owned  restricted  shares of Common Stock for at least one
year is entitled to sell, within any three-month period, a number of shares that
does not exceed the greater of 1% of the total number of  outstanding  shares of
the same class, if the Common Stock is quoted on a stock  exchange,  the average
weekly  trading  volume  during the four  calendar  weeks  preceding the sale. A
person who presently is not and who has not been an affiliate of the Company for
at least three months  immediately  preceding the sale and who has  beneficially
owned the shares of Common Stock for at least two years is entitled to sell such
shares  under  Rule  144(k),  without  regard to any of the  volume  limitations
described  above.  In  addition,  the  Company  has issued  warrants to purchase
2,750,000  shares of Common Stock  ("Rule 701  Warrants")  in reliance  upon the
provisions  of Rule 701 of the  Securities  Act,  pursuant to which,  in certain
circumstances,  such Rule 701  Warrants may be sold.  Certain  holders of Common
Stock  have  executed  lock  up  agreements  with  the  Company.  The  sale,  or
availability for sale, of substantial amounts of the Company's securities in the
public market  subsequent to this  Prospectus,  including the securities  issued
pursuant to Rule 144, Rule 701 or otherwise,  could adversely  affect the market
price of the  Common  Stock and could  impair  the  Company's  ability  to raise
additional  capital through the sale of its equity securities or debt financing.
The  availability  of  Rule  144  and  Rule  701 to the  holders  of  restricted
securities  of the Company would be  conditioned  on, among other  factors,  the
availability of certain public information concerning the Company.

19.  Current  Prospectus  and State  Registration  Required to Exercise  Class A
Warrants.

     The Class A Warrants may not be exercised by the holders  thereof unless at
the time of  exercise a  registration  statement  covering  the shares of Common
Stock  issuable  upon  exercise  of the Class A Warrants is  effective  and such
shares of  Common  Stock  have been  registered  under  the  Securities  Act and
qualified,  or deemed to be exempt,  under the securities  laws of the states of
residence of the respective holders of such Class A Warrants.  While the Class A
Warrants are being registered herewith, there can be no assurance, however, that
such  registration  statement  will remain current or that such Class A Warrants
will be properly  qualified under  applicable state securities laws, the failure
of which may result in the  exercise  of the Class A Warrants  and the resale or
other disposition of Common Stock issued upon such exercise becoming unlawful.

20. Potential Adverse Effect of Redemption of Class A Warrants.

     The Class A Warrants may be redeemed by the Company at any time  commencing
two years from the date of this  Prospectus  and ending five years from the date
of this  Prospectus,  


                                       19
<PAGE>

at a redemption  price of $.05 per Class A Warrant  upon 30 days' prior  written
notice  provided  the closing bid price of the Common  Stock on AMEX (or another
national  securities  exchange) for 20 consecutive trading days ending within 10
days of the notice of  redemption  equals or exceeds  $9.00 per share subject to
adjustment.  Redemption  of the Class A  Warrants  could  force the  holders  to
exercise the Class A Warrants  and pay the exercise  price at a time when it may
be disadvantageous for the holders to do so, to sell the Class A Warrants at the
then  current  market price when they might  otherwise  wish to hold the Class A
Warrants, or to accept the redemption price, which is likely to be substantially
less than the market value of the Class A Warrants at the time of redemption.

21. Exercise of Derivatives May Have Dilutive Effect on Market.

     The  Derivatives  provide for,  during their term, an  opportunity  for the
holder  to  profit  from a rise  in the  market  price,  of  which  there  is no
assurance, with resulting dilution in the ownership interest in the Company held
by the then  present  stockholders.  Holders of  Derivatives  most likely  would
exercise or convert the Derivatives and purchase the underlying  Common Stock at
a time when the  Company  may be able to obtain  capital  by a new  offering  of
securities on terms more favorable than those provided by such  Derivatives,  in
which  event  the terms on which the  Company  may be able to obtain  additional
capital would be affected adversely.

22. Conflicts of Interest.

     All of the members of the Company's  Scientific Advisory Board are employed
other than by the Company and may have  commitments to or consulting or advisory
contracts  with other  entities  (which may include  competitors of the Company)
that may limit  their  availability  to the  Company.  While each  member of the
Company's   Scientific   Advisory  Board  does  execute  a  non-disclosure   and
non-competition  agreement  with  respect  to  proprietary  data  that he or she
receives from the Company,  there can be no assurance that these agreements will
absolutely  protect  the Company  from the results of such data being  revealed,
accidentally or otherwise, by a member of its Scientific Advisory Board.

23. Absence of Dividends.

     The Company intends to retain future earnings, if any, to provide funds for
the operations of its business and, accordingly,  does not anticipate paying any
dividends on its Common Stock in the reasonably foreseeable future.

                                 USE OF PROCEEDS

     The  Company  will  not  receive  proceeds  from  any  sale of the  Selling
Securityholder  Securities.  The proceeds to be received by the Company from the
exercise of the  Derivatives  (assuming all of such  securities are  exercised),
will be  $7,680,989.  The  Company  intends  to use such  proceeds  for  general
corporate purposes.  Pending use of the proceeds, they will be invested in short
term, interest bearing securities or money market funds.

                                    DILUTION

     The following discussion assumes that all of the Derivatives are exercised:

     As of September 30, 1997,  the net tangible book value of the Common Stock,
based on the balance  sheet at  September  30,  1997,  as  adjusted  for the net
proceeds of the September 2, 1997 and  September  22, 1997 private  placement of
Common  Stock,  was  $9,926,716  or $.48 per share.  Net tangible book value per
share represents the amount of the tangible assets, $11,340,870, less the amount
of its liabilities,  $1,414,154, divided by the number of shares of Common Stock
outstanding,  20,501,993  (as  adjusted).  Without taking into account any other
changes in the net tangible book value of the Company after  September 30, 1997,
upon the exercise of all of the Derivatives (2,169,771),  and the receipt of the
net proceeds  therefrom  ($7,680,989),  the pro forma net tangible book value of
the Common Stock, would be $17,607,705. Upon dividing the pro forma net tangible
book value by the pro forma amount of Common Stock outstanding (22,671,764), the
pro forma net tangible book value per share is $.78 per share,  representing  an
immediate  increase  in the net  tangible  book  value of $.30 per  share to the
present  shareholders.  Dilution  to new  investors,  since new  investors  will
purchase  shares at varying and  fluctuating  prices,  represents the difference
between the market price of the Common Stock and the pro forma net tangible book
value per share after the  issuance of all the shares of Common  Stock  issuable
upon exercise of the Derivatives.

                       RESALES BY SELLING SECURITYHOLDERS

     This   Prospectus   relates  to  the   proposed   resale  by  the   Selling
Securityholders of the Securities.  The following table sets forth as of January
29, 1998 certain information with respect to the persons for whom the Company is
registering  the  Securities  for sale to the public except as footnoted  below.
None of such  persons  has had a  material  relationship  with or has  held  any
position or office with the Company or any of its affiliates within three years,
other than as footnoted  below. The Company will not receive any of the proceeds
from the sale of the Securities.  If the Derivatives are exercised,  the Company
would receive $7,680,989.

                              PLAN OF DISTRIBUTION

     The Selling  Securityholders  may offer and sell shares of Common Stock and
Warrants from time to time in the discretion of the Selling  Securityholders  on
AMEX or in the over-the-counter  market or otherwise at prices and at terms then
prevailing  or at  prices  related  to the  then  current  market  price,  or at
negotiated  prices.  The distribution of the shares of Common Stock and Warrants
may be effected from time to time in one or more transactions including, without
limitation: (a) a block trade in which the broker-dealer so engaged will attempt
to sell the Common  Stock and  Warrants as agent,  but may position and resell a
portion of the block as principal to facilitate the  transaction;  (b) purchases
by a broker or dealer as  principal  and resale by such broker or dealer for its
account pursuant to this  Prospectus;  (c) ordinary  brokerage  transactions and
transactions in which the broker solicits  purchasers;  and (d)  face-to-face or
other direct  transactions  between the Selling  Securityholders  and purchasers
without  a   broker-dealer   or  other   intermediary.   In   effecting   sales,
broker-dealers or agents engaged by the Selling  Securityholders may arrange for
other broker-dealers or agents to participate. From time to time, one or more of
the Selling Securityholders may pledge, hypothecate or grant a security interest
in some or all of the common  Stock  owned by them,  and the  pledgees,  secured
parties or persons to whom such securities have been  hypothecated  shall,  upon
foreclosure  in the event of  default,  be deemed to be Selling  Securityholders
hereunder.  In addition, the Selling  Securityholders may from time to time sell
short the Common Stock of the Company,  and in such  instances,  this Prospectus
may be delivered in connection with such short sale and the Common Stock offered
hereby may be used to cover such short sale.

     Sales of Selling  Securityholders'  Common  Stock and  Warrants may also be
made  pursuant  to Rule 144 under the  Securities  Act,  where  applicable.  The
Selling  Securityholders' shares may also be offered in one or more underwritten
offerings,  on a firm commitment or best efforts basis. The Company will receive
no proceeds from the sale of Common Stock by the Selling Securityholders.


                                       27
<PAGE>

     To the extent  required under the Securities  Act, the aggregate  amount of
Selling  Securityholders'  Common Stock and Warrants being offered and the terms
of the offering, the names of any such agents, brokers,  dealers or underwriters
and any  applicable  commission  with respect to a particular  offer will be set
forth in an  accompanying  Prospectus  supplement.  Any  underwriters,  dealers,
brokers or agents  participating  in the  distribution  of the Common  Stock and
Warrants  may  receive  compensation  in the  form  of  underwriting  discounts,
concessions, commissions or fees from a Selling Securityholder and/or purchasers
of Selling  Securityholders'  shares of Common Stock and/or  Warrants,  for whom
they may act. In addition,  sellers of Selling Securityholders' shares of Common
Stock and/or Warrants may be deemed to be underwriters  under the Securities Act
and any profits on the sale of Selling  Securityholders'  shares of Common Stock
or  Warrants  by them may be deemed to be  discounts  or  commissions  under the
Securities Act. Selling  Securityholders  may have other business  relationships
with the Company and its  subsidiaries  or affiliates in the ordinary  course of
business.

     From time to time each of the Selling Securityholders may transfer, pledge,
donate or assign Selling Securityholders' shares of Common Stock and Warrants to
lenders, family members and others and each of such persons will be deemed to be
a  "Selling  Securityholder"  for  purposes  of this  Prospectus.  The number of
Selling  Securityholders' shares of Common Stock and Warrants beneficially owned
by those  Selling  Securityholders  who so  transfer,  pledge,  donate or assign
Selling Securityholders' shares of Common Stock or Warrants will decrease as and
when  they  take  such   actions.   The  plan  of   distribution   for   Selling
Securityholders'  shares  of Common  Stock  and  Warrants  sold  hereunder  will
otherwise remain  unchanged,  except that the transferees,  pledgees,  donees or
other successors will be Selling Securityholders hereunder.

     Including,   and  without  limiting  the  foregoing,   in  connection  with
distributions  of the  Common  Stock,  a Selling  Securityholder  may enter into
hedging  transactions with  broker-dealers  and the broker-dealers may engage in
short  sales of the Common  Stock in the course of hedging  the  positions  they
assume with such Selling Securityholder. A Selling Securityholder may also enter
into option or other transactions with  broker-dealers that involve the delivery
of the Common  Stock to the  broker-dealers,  who may then  resell or  otherwise
transfer such Common Stock. A Selling Securityholder may also loan or pledge the
Common Stock to a broker-dealer  and the broker-dealer may sell the Common Stock
so loaned or upon  default may sell or  otherwise  transfer  the pledged  Common
Stock.

     Under  applicable rule and  regulations  under the Exchange Act, any person
engaged  in the  distribution  of the Common  Stock may not bid for or  purchase
shares of Common  Stock  during a period  which  commences  one  business day (5
business  days,  if the  Company's  public float is less than $25 million or its
average  daily  trading  volume is less than  $100,000)  prior to such  person's
participation  in the  distribution,  subject to exceptions for certain  passive
market making activities.  In addition and without limiting the foregoing,  each
Selling  Securityholder will be subject to applicable provisions of the Exchange
Act and the rules and regulations  thereunder,  including,  without  limitation,
Regulation M which  provisions  may limit the timing of  purchases  and sales of
shares of the Company's Common Stock by such Selling Securityholder.

              DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the Company,
the  Company  has  been  advised  that in the  opinion  of the  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore  unenforceable.  In the event  that a claim  for  indemnification
against  such  liabilities  (other  than the  payment by the  Company of expense
incurred or paid by a director, officer, or controlling person of the Company in
the  successful  defense of any action,  suit or proceeding) is asserted by such
director,  officer or controlling  person of the Company in connection  with the
securities  being  registered,  the Company  will,  unless in the opinion of its
counsel  the matter has been  settled by a  controlling  precedent,  submit to a
court of appropriate  jurisdiction the question whether such  indemnification by
it is against  public  policy as  expressed  in the  Securities  Act and will be
governed by the final adjudication of such issues.
