                   HEMISPHERx BIOPHARMA, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1: BASIS OF PRESENTATION

The  accompanying  consolidated  financial  statements  include the  accounts of
Hemispherx  BioPharma,  Inc., a Delaware  corporation and its subsidiaries.  All
significant intercompany accounts and transactions have been eliminated.

In the opinion of management,  all adjustments necessary for a fair presentation
of such consolidated  financial statements have been included.  Such adjustments
consist  of  normal  recurring  items.   Interim  results  are  not  necessarily
indicative of results for a full year.

The interim consolidated financial statements and notes thereto are presented as
permitted by the Securities and Exchange  Commission  (SEC),  and do not contain
certain information which will be included in our annual consolidated  financial
statements and notes thereto.

These consolidated  financial  statements should be read in conjunction with our
consolidated financial statements included in our annual report on Form 10-K for
the year ended December 31, 2004, as filed with the SEC on March 16, 2005.

NOTE 2: STOCK BASED COMPENSATION

The Company follows Statement of Financial  Accounting  Standards(SFAS) No. 123,
"Accounting  for  Stock-Based   Compensation."  We  chose  to  apply  Accounting
Principal Board Opinion 25 and related  interpretations  in accounting for stock
options granted to our employees.

The Company  provides pro forma  disclosures of  compensation  expense under the
fair value method of SFAS No. 123,  "Accounting for  Stock-Based  Compensation,"
and SFAS No. 148,  "Accounting  for  Stock-Based  Compensation-  Transition  and
Disclosure."

The weighted average assumptions used for the period presented are as follows:

                                          March 31,
                                        2004        2005
Risk-free interest rate                     -         4.81%
Expected dividend yield                     -          -
Expected lives                              -       5 years
Expected volatility                         -        58.78%


Had compensation cost for the Company's option plans been determined,  using the
fair value method at the grant dates,  the effect on the  Company's net loss and
loss per share for the Three  months  ended  March 31,  2004 and 2005 would have
been as follows:

Note 3: INVESTMENT IN UNCONSOLIDATED AFFILIATES

Investments  include an equity  investment  of  $35,000  in  Chronix  Biomedical
("Chronix").  Chronix  focuses upon the  development of diagnostics  for chronic
diseases.  This initial  investment  was made in May 31, 2000 by the issuance of
50,000  shares of the Company's  common stock from the treasury.  On October 12,
2000, the Company issued an additional  50,000 shares of its common stock and on
March 7, 2001 the Company issued 12,000 more shares of its common stock from the
treasury  to  Chronix  for an  aggregate  equity  investment  of  $700,000.  The
percentage ownership in Chronix is approximately 5.4% and is accounted for under
the cost method of  accounting.  During the quarter ended  December 31, 2002, we
recorded  a non-cash  charge of  $292,000  with  respect  to our  investment  in
Chronix.  The Company recorded an additional  non-cash charge of $373,000 during
the quarter ended  September 30, 2004,  due to evidence of a further  decline in
Chronix's market value. This impairment  reduces our carrying value to reflect a
permanent  decline  in  Chronix's  market  value  based  on  its  then  proposed
investment offerings.

NOTE 4: INVENTORIES

The Company uses the lower of first-in, first-out ("FIFO") cost or market method
of accounting for inventory.

Inventories consist of the following:

                                December 31, 2004    March 31, 2005
                                -----------------    --------------
Raw materials-work in process       $ 1,711,000      $1,711,000
Finished goods,
net of $225,000 reserve                 437,000         228,000
                                        -------        --------
                                    $ 2,148,000      $1,939,000
                                    ===========      ==========

The  Company's  reserve for  potentially  stale  inventory as of March 31, 2005,
totaled  $225,000  for  Alferon N  finished  goods that may not be sold prior to
their 18 month shelf-life expiration.  Also, the Company may consume some or all
of this potentially  stale inventory in its R&D efforts.  The Company  completed
tests in 2004 to extend the product  shelf life to 24 months.  The Company filed
its annual report with the FDA in December 2004 including  documentation for the
extension of  shelf-life  to 24 months.  The Company  plans to file with the FDA
requesting  approval  to relabel  2,000 vials of Alferon N  Injection(R)  within
finished goods. We anticipate a response from the FDA by the end of June 2005.

NOTE 5:  REVENUE AND LICENSING FEE INCOME

The Company  executed a Memorandum of  Understanding  (MOU) in January 2004 with
Fujisawa Deutschland GmbH, ("Fuji") a major pharmaceutical corporation, granting
them an  exclusive  option  for a limited  number of months to enter a Sales and
Distribution Agreement with exclusive rights to market Ampligen(R) for ME/CFS in
Germany, Austria and Switzerland.  The MOU required the Company to file the full
report on the results of the Company's  AMP 516 Clinical  Trial with Fuji by May
31,  2004.  If the full report was not provided to Fuji by May 31, 2004 and Fuji
did not wish to exercise  its option,  The Company  would have been  required to
refund one half of the 400,000 Euro fee.  The Company  submitted  their  initial
report  to Fuji on May 28,  2004  and  responded  to  subsequent  inquiries  for
additional  information.  The  option  period  ends 12 weeks  after the later of
Fuji's  review  of the full  report  on the  results  of the  Company's  Amp 516
clinical  trial  and  Fuji's  meeting  with  three  of  the  trial's   principal
investigators.   The  Company   received   an  initial  fee  of  400,000   Euros
(approximately  $497,000  US). If the Company did not provide them with the full
report by December  31, 2004 and Fuji did not wish to exercise  its option,  the
Company  would be required  to refund the entire  fee. On November 9, 2004,  the
Company and Fuji  terminated  the MOU by mutual  agreement.  The Company did not
agree  on the  process  to be  utilized  in  certain  European  Territories  for
obtaining  commercial  approval for the sale of  Ampligen(R) in the treatment of
patients suffering from Chronic Fatigue Syndrome (CFS). Instead of a centralized
procedure,  and in order to obtain an earlier commercial approval of Ampligen(R)
in Europe, the Company has determined to follow a decentralized filing procedure
which was not anticipated in the MOU. The Company believes that it now is in the
best interest of our stockholders to potentially  accelerate entry into selected
European  markets whereas the original MOU specified a centralized  registration
procedure.  Pursuant to mutual  agreement  of the  parties the Company  refunded
200,000 Euros to Fuji.  The Company has recorded the remaining  200,000 Euros as
an accrued  liability as of December 31, 2004. The Company is currently  holding
the 200,000 Euros pending  further  developments in accordance with the mutually
agreed upon termination with Fuji.

Revenues for  non-refundable  license fees are recognized  under the Performance
Method-Expected  Revenue.  This method  considers  the total  amount of expected
revenue  during  the  performance  period,  but  limits  the  amount of  revenue
recognized  in a period to total  non-refundable  cash  received  to date.  This
limitation is appropriate  because future  milestone  payments are contingent on
future events.

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

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

During the period  ended March 31,  2005,  the Company did not receive any grant
monies from local, state and or Federal Agencies.

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

Revenues from the sale of product are recognized when the product is shipped, as
title is  transferred  to the  customer.  The  Company  has no other  obligation
associated with its products once shipment has occurred.

Note 6: ACQUISITION OF ASSETS OF INTERFERON SCIENCES, INC. ("ISI")

On March 11, 2003, the Company  acquired from ISI, ISI's  inventory of ALFERON N
Injection(R)  and a  limited  license  for  the  production,  manufacture,  use,
marketing and sale of this product. As partial consideration, the Company issued
487,028 shares of its common stock to ISI Pursuant to their agreements with ISI,
the Company registered these shares for public sale and ISI has reported that it
has sold all of these  shares.  The Company also agreed to pay ISI 6% of the net
sales of ALFERON N Injection(R).

On March 11, 2003,  the Company also entered into an agreement to purchase  from
ISI all of its rights to the  product  and other  assets  related to the product
including,  but not limited to, real estate and machinery. For these assets, the
Company agreed to issue to ISI an additional 487,028 shares and to issue 314,465
shares and 267,296 shares,  respectively to the American  National Red Cross and
GP  Strategies  Corporation,  two creditors of ISI. The Company  guaranteed  the
market  value of all but  62,500  of these  shares  to be $1.59 per share on the
termination date. As discussed below, the Company issued all of these shares and
ISI, GP Strategies  and the American  National Red Cross have reported that they
have sold all of their shares.

The Company also agreed to satisfy other  liabilities of ISI which were past due
and secured by a lien on ISI's real estate and to pay ISI 6% of the net sales of
products containing natural alpha interferon.

On May 30, 2003, the Company issued the shares to GP Strategies and the American
National Red Cross. Pursuant to our agreements with ISI and these two creditors,
we registered the foregoing  shares for public sale. The Company  guaranteed the
market  value of all but  62,500 of these  shares to be $1.59  per  share.  As a
result at December 31, 2003 the  guaranteed  value of these  shares  ($491,000),
which had not been sold by these two creditors,  were reclassified to redeemable
common  stock.  At  December  31,  2004,  all  shares had been sold by these two
creditors and the redeemable common stock was reclassed to equity.

On November 6, 2003, the Company acquired and subsequently paid, the outstanding
ISI property tax lien  certificates  in the  aggregate  amount of $457,000  from
certain investors.  These tax liens were issued for property taxes and utilities
due for 2000, 2001 and 2002.

In March  2004,  the  Company  issued  487,028  shares  to ISI to  complete  the
acquisition  of the balance of ISI's rights to market its product as well as its
production  facility  in New  Brunswick,  New  Jersey.  ISI has  sold all of its
shares.  The  aggregated  cost  of the  land  and  buildings  was  approximately
$3,316,000. The cost of the land and buildings was allocated as follows:

                                    Land              $   423,000

On July 10, 2003,  the Company  issued an aggregate of  $5,426,000  in principal
amount of 6% Senior  Convertible  Debentures  due July 31,  2005 (the "July 2003
Debentures")  and an aggregate of 507,102 Warrants (the "July 2008 Warrants") to
the same investors who purchased the March  Debentures,  in a private  placement
for  aggregate  proceeds of  $4,650,000.  Pursuant to the terms of the July 2003
Debentures, $1,550,000 of the proceeds from the sale of the July 2003 Debentures
were to have been held back and  released  to the  Company  if, and only if, the
Company  acquired  ISI's  facility  with in a set  timeframe.  These  funds were
released to the Company in October  2003  although  the Company had not acquired
ISI's  facility at that time. The July 2003  Debentures  mature on July 31, 2005
and bear  interest at 6% per annum,  payable  quarterly  in cash or,  subject to
satisfaction  of certain  conditions,  common stock.  Any shares of common stock
issued to the  investors  as payment of  interest  shall be valued at 95% of the
average closing price of the common stock during the five  consecutive  business
days ending on the third  business  day  immediately  preceding  the  applicable
interest payment date.

The July 2003  Debentures are  convertible at the option of the investors at any
time  through  July 31,  2005 into shares of the  Company's  common  stock.  The
conversion  price under the July 2003  Debentures  was fixed at $2.14 per share;
however,  as part of the subsequent  debenture  placement  closed on October 29,
2003 (see  below),  the  conversion  price  under the July 2003  Debentures  was
lowered to $1.89 per share.  The  conversion  price is subject to adjustment for
anti-dilution  protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in  effect.  In  addition,  in the  event  that  the  Company  does  not pay the
redemption  price at maturity,  the  Debenture  holders,  at their  option,  may
convert the balance due at the lower of (a) the conversion  price then in effect
and (b) 95% of the lowest  closing  sale price of our  common  stock  during the
three trading days ending on and including the conversion date.

The July 2008 Warrants received by the investors,  as amended, were an aggregate
of 507,102  shares of common  stock at a price of $2.46 per share.  The  amended
Warrants  resulted in an additional debt discount of  approximately  $335,000 in
2004.  These  Warrants were exercised in July 2004 which produced gross proceeds
in the amount of $1,247,470.

On June 25,  2003,  the Company  issued to each of the March 12, 2003  Debenture
holders  warrants to acquire at any time  through  June 25, 2008 an aggregate of
1,000,000  shares of common  stock at a price of $2.40 per share (the "June 2008
Warrants"). These warrants were issued as incentive for the debenture holders to
exercise prior warrant  issuances.  This issuance resulted in an additional debt
discount  to the March  debentures  of  $2,640,000.  Pursuant  to the  Company's
agreement  with the Debenture  holders,  the Company has  registered  the shares
issuable  upon  exercise  of these June 2008  Warrants  for public  sale.  These
warrants were  exercised in May 2004 and the Company  received gross proceeds of
$2,400,000.

As of December  31, 2004,  the  investors  had  converted  the total  $5,426,000
principal of the July Debentures into 2,870,900 shares of common stock.

On October 29, 2003,  the Company issued an aggregate of $4,142,357 in principal
amount of 6% Senior  Convertible  Debentures  due October 31, 2005 (the "October
2003  Debentures")  and an  aggregate of 410,134  Warrants  (the  "October  2008
Warrants") in a private  placement for aggregate  gross  proceeds of $3,550,000.
Pursuant to the terms of the October 2003 Debentures, $1,550,000 of the proceeds
from the sale of the  October  2003  Debentures  were  held  back and were to be
released to the Company if, and only if, the  Company  acquired  ISI's  facility
within 90 days of January 26,  2004 and  provide a mortgage  on the  facility as
further  security for the October 2003  Debentures.  In March 2004,  the Company
acquired the facility and the Company subsequently  provided the mortgage of the
facility to the Debenture holders. The October 2003 Debentures mature on October
31,  2005 and bear  interest  at 6% per  annum,  payable  quarterly  in cash or,
subject to  satisfaction  of certain  conditions,  common  stock.  Any shares of
common stock issued to the  investors as payment of interest  shall be valued at
95% of the average closing price of the common stock during the five consecutive
business  days  ending on the  third  business  day  immediately  preceding  the
applicable interest payment date.

Upon completing the sale of the October 2003  Debentures,  the Company  received
$3,275,000  in net  proceeds  consisting  of  $1,725,000  from the October  2003
Debentures and $1,550,000 that had been withheld from the July 2003  Debentures.
As noted above, pursuant to the terms of the October 2003 Debentures, $1,550,000
of the proceeds from the sale of the October 2003 Debentures had been held back.
However,  these proceeds were released to the Company in April 2004. As required
by the  Debentures,  the Company has  provided a mortgage on the ISI facility as
further security for the Debentures.

The October 2003  Debentures  are  convertible at the option of the investors at
any time  through  October  31,  2005  into  shares  of our  common  stock.  The
conversion  price under the October 2003 Debentures is fixed at $2.02 per share,
subject to adjustment for anti-dilution  protection for issuance of common stock
or securities convertible or exchangeable into common stock at a price less than
the conversion price then in effect. In addition,  in the event that the Company
does not pay the redemption price at maturity,  the Debenture holders,  at their
option,  may convert the  balance due at the lower of (a) the  conversion  price
then in effect and (b) 95% of the lowest  closing sale price of our common stock
during the three trading days ending on and including the conversion date.

The October 2008 Warrants, as amended, received by the investors were to acquire
an  aggregate  of 410,134  shares of common stock at a price of $2.32 per share.
The amended  Warrants  resulted in a reduction in debt discount of approximately
$53,000 in 2004. These Warrants were exercised in July 2004 which produced gross
proceeds in the amount of $951,510.

As of March 31, 2005, the investors had converted $2,071,178 principal amount of
the Debenture into 1,025,336 shares of Common Stock.

On January 26, 2004,  the Company issued an aggregate of $4,000,000 in principal
amount of 6% Senior  Convertible  Debentures  due January 31, 2006 (the "January
2004  Debentures"),  an aggregate of 790,514 warrants (the "July 2009 Warrants")
and  158,103  shares of common  stock,  and  Additional  Investment  Rights  (to
purchase  up to an  additional  $2,000,000  principal  amount  of  January  2004
Debentures  commencing  in six months) in a private  placement for aggregate net
proceeds of $3,695,000.  The January 2004 Debentures  mature on January 31, 2006
and bear  interest at 6% per annum,  payable  quarterly  in cash or,  subject to
satisfaction  of certain  conditions,  common stock.  Any shares of common stock
issued to the  investors  as payment of  interest  shall be valued at 95% of the
average closing price of the common stock during the five  consecutive  business
days ending on the third  business  day  immediately  preceding  the  applicable
interest  payment  date.  Commencing  July 26, 2004,  the Company is required to
start  repaying  the then  outstanding  principal  amount under the January 2004
Debentures in monthly  installments  amortized over 18 months in cash or, at our
option, in shares of common stock. After one installment  payment of $111,111 in
our common  stock,  one  debenture  holder  exercised its right to waive further
installment  payments on their note.  Any shares of common  stock  issued to the
investors as installment  payments shall be valued at 95% of the average closing
price of the common stock during the 10-day  trading  period  commencing  on and
including  the  eleventh  trading day  immediately  preceding  the date that the
installment is due.

The January 2004  Debentures  are  convertible at the option of the investors at
any time through January 31, 2006 into shares of the Company's common stock. The
conversion price under the January 2004 Debentures was fixed at $2.53 per share,
subject to adjustment for anti-dilution  protection for issuance of common stock
or securities convertible or exchangeable into common stock at a price less than
the conversion price then in effect. In addition,  in the event that the Company
does not pay the redemption price at maturity,  the Debenture holders,  at their
option,  may convert the  balance due at the lower of (a) the  conversion  price
then in effect and (b) 95% of the lowest  closing sale price of our common stock
during the three trading days ending on and including the conversion  date. Upon
completion  of the August  2004  Private  Placement,  the  conversion  price was
lowered to $2.08 per share.  As of March 31, 2005,  the  remaining  principal on
these  debentures was $2,749,740.  The investors  converted  $139,150  principal
amount of the January 2004  Debenture  into 55,000  shares of common  stock.  In
addition,  installment  payments  of  $1,111,110  were  made  to  the  Company's
investors amounting to 574,971 shares of the Company's common stock.

There are two classes of July 2009 Warrants  received by the Investors:  Class A
and Class B. The Class A  warrants  are to acquire  any time from July 26,  2004
through July 26, 2009 an aggregate of up to 395,257  shares of common stock at a
price of $3.29 per share. The Class B warrants are to acquire any time from July
26, 2004 through  July 26, 2009 an  aggregate of up to 395,257  shares of common
stock at a price of $5.06 per share.  On January 27, 2004, the exercise price of
these July 2009  Class A and Class B Warrants  were reset to the lesser of their
respective  exercise price then in effect or a price equal to the average of the
daily price of the common stock  between  January 27, 2004 and January 26, 2005.
The exercise  price (and the reset price) under the July 2009  Warrants  also is
subject to similar adjustments for anti-dilution protection. Notwithstanding the
foregoing,  the exercise prices as reset or adjusted for anti-dilution,  will in
no event be less than  $2.58 per  share.  Upon  completion  of the  August  2004
Private Placement, the exercise price was lowered to $2.58 per share.

The Company also issued to the investors  Additional  Investment Rights pursuant
to which the investors have the right to acquire up to an additional  $2,000,000
principal amount of January 2004 Debentures (the July 2004 Debentures") from us.
The July 2004  Debentures  are identical to the January 2004  Debentures  except
that the  conversion  price is $2.58.  The investors  exercised  the  Additional
Investment  Rights on July 13, 2004 and the  Company  received  net  proceeds of
$1,860,000.  Upon  completion of the August 2004 Private  Placement (see below),
the conversion  price was lowered to $2.08 per share.  As of March 31, 2005, the
Debenture holders had not converted any portion of this debenture.

On May 14, 2004, in consideration for the Debenture  holders' exercise of all of
the June 2008  Warrants,  the Company  issued to the holders  warrants (the "May
2009  Warrants")  to purchase an aggregate of 1,300,000  shares of the Company's
common  stock.  As a result the  warrants  were valued at  $2,355,000  which was
recorded as additional debt discounts.  The Company issued  1,000,000  shares of
common stock and received gross proceeds of $2,400,000  from the exercise of the
June 2008 Warrants.

The May 2009 Warrants are to acquire at any time commencing on November 14, 2004
through  April 30, 2009 an aggregate  of  1,300,000  shares of common stock at a
price of $4.50 per share.  On May 14, 2005, the exercise price of these May 2009
Warrants  will  reset to the  lesser of the  exercise  price then in effect or a
price equal to the average of the daily  price of the common  stock  between May
15, 2004 and May 13, 2005.  The  exercise  price (and the reset price) under the
May 2009 Warrants also is subject to adjustments  for  anti-dilution  protection
similar  to those in the other  Warrants.  Notwithstanding  the  foregoing,  the
exercise price as reset or adjusted for anti-dilution,  will in no event be less
than $4.008 per share.  This  transaction  generated a non-cash  charge of about
$2,300,000 financing costs in the second quarter of 2004. Upon completion of the
August 2004 Private  Placement  (see below),  the exercise  price was lowered to
$4.008 per share.

The Company entered into  Registration  Rights  Agreements with the investors in
connection  with the issuance of (i) the  Debentures;  (ii) the June 2008,  July
2008,  October  2008,  July  2009,  and May  2009  Warrants  (collectively,  the
"Warrants");  and (iii) the  shares  issued in  January  2004.  Pursuant  to the
Registration  Rights  Agreements  the  Company has  registered  on behalf of the
investors  the  shares  issued to them in  January  2004 and 135% of the  shares
issuable  upon  conversion  of the  Debentures  and upon  exercise of all of the
Warrants.  If, subject to certain exceptions,  sales of all shares so registered
cannot be made pursuant to the registration statements, then the Company will be
required  to pay to the  investors  their pro rata  share of  $.00067  times the
outstanding  principal amount of the relevant  Debentures for each day the above
condition exists.

As discussed below,  Section 713 of the American Stock Exchange ("AMEX") Company
Guide  provides  that  the  Company  must  obtain  stockholder  approval  before
issuance,  at a price  per  share  below  market  value,  of  common  stock,  or
securities  convertible  into  common  stock,  equal  to  20%  or  more  of  our
outstanding  common stock (the "Exchange  Cap").  The Debentures  (including the
July 2004  Debentures)  and Warrants have provisions that require us to pay cash
in lieu of issuing  shares upon  conversion of the Debentures or exercise of the
Warrants if the Company is prevented  from  issuing  such shares  because of the
Exchange Cap. In May 2004, the Debenture  holders agreed to amend the provisions
of these  Debentures  and Warrants to limit the maximum amount of funds that the
holders could receive in lieu of shares upon conversion of the Debentures and/or
exercise  of the  Warrants  in the event that the  Exchange  Cap was  reached to
119.9%  of the  conversion  price of the  relevant  Debentures  and 19.9% of the
relevant  Warrant  exercise price.  See below for the accounting  effect on this
matter.

As of March 31, 2005, the investors have converted  $13,062,328 principal amount
of debt from the Debentures  issued in March,  July and October 2003 and January
2004 into  7,667,674  shares of our common  stock.  $1,111,110  of principal was
repaid  with the  issuance  of  574,971  shares  of  stock.  The  March and July
Debentures have been fully  converted.  The remaining  principal  balance on the
outstanding  Debentures is convertible into shares of our stock at the option of
the investors at any time,  through the maturity date. In addition,  the Company
has paid $1,300,000  into the debenture cash  collateral  account as required by
the terms of the October 2003  Debentures.  The amounts  paid through  March 31,
2005 have been accounted for as advances receivable and are reflected as such on
the accompanying balance sheet as of March 31, 2005. The cash collateral account
provides  partial  security for repayment of the  outstanding  Debentures in the
event of default.

By agreement  with  Cardinal  Securities,  LLC, for general  financial  advisory
services and in conjunction  with the private  debenture  placements in July and
October  2003 and in  January,  May and July 2004,  the  Company  paid  Cardinal
Securities, LLC an investment banking fee equal to 7% of the investments made by
the two  Debenture  holders and issued to  Cardinal  the  following  warrants to
purchase common stock: (i) 112,500  exercisable at $2.57 per share;  (ii) 87,500
exercisable  at $2.42 per  share;  and (iii)  100,000  exercisable  at $3.04 per
share.  The $2.57 warrants expire on July 10, 2008, the $2.42 warrants expire on
October 29, 2008 and the $3.04 warrants  expire on January 5, 2009.  With regard
to the exercise of the June 2008 Warrants and issuance of the May 2009 Warrants,
Cardinal  received  an  investment  banking  fee of 7%, half in cash and half in
shares.  With regard to the exercise of the Additional  Investment  Rights,  the
July 2008 and October  2008  Warrants  and  issuance of the July 2009  Warrants,
Cardinal received an investment banking fee of 7%, 146,980 in cash and 22,703 in
shares as well as 50,000  warrants  exercisable  at $4.07  expiring  on July 12,
2009.  By  agreement  with  Cardinal,  the  Company  has  registered  all of the
foregoing  shares and  shares  issuable  upon  exercise  of the above  mentioned
warrants for public sale and the Company has agreed to register the balance.  As
a result  of all of the  transactions  discussed  above,  the  Company  recorded
$1,430,000 as additional debt discounts.

Section 713 of the AMEX  Company  Guide  provides  that the Company  must obtain
stockholder  approval before issuance,  at a price per share below market value,
of common stock, or securities  convertible  into common stock,  equal to 20% or
more of our outstanding common stock (the "Exchange Cap"). Taken separately, the
July 2003,  October 2003 and January 2004 Debenture  transactions do not trigger
Section 713.  However,  the AMEX took the position  that the three  transactions
should be  aggregated  and, as such,  stockholder  approval was required for the
issuance of common stock for a portion of the potential exercise of the warrants
and conversion of the Debentures in connection with the January 2004 Debentures.
The amount of  potential  shares that the Company  could exceed the Exchange Cap
amounted to approximately  1,299,000.  In accordance with EITF 00-19, Accounting
For Derivative  Financial  Instruments  Indexed to and Potentially  Settled in a
Company's  Own Stock,  the Company  recorded on January 26,  2004,  a redemption
obligation of  approximately  $1,244,000.  This liability  represented  the fair
market value of the warrants and beneficial  conversion  feature  related to the
1,299,000 shares.

In addition, in accordance with EITF 00-19, the Company revalued this redemption
obligation  associated with the beneficial conversion feature and warrants as of
March 31, 2004.  The Company  recorded an additional  redemption  obligation and
finance  charge of $947,000 as a result of this  revaluation.  Upon  stockholder
approval,  our redemption  obligation was recorded as additional paid in capital
as of the date approval was received.

The  requisite  stockholder  approval  was  obtained  at our  Annual  Meeting of
Stockholders  on June 23,  2004.  In  accordance  with EITF  00-19,  the Company
revalued this redemption  obligation  associated with the beneficial  conversion
feature and  warrants as of June 23, 2004.  The Company  recorded a reduction in
the value of the  redemption  obligation  and financing  charge of $260,000 as a
result  of  this  revaluation.   In  addition,   upon  receiving  the  requisite
stockholder approval,  this redemption obligation was reclassified as additional
paid in capital as of the date the approval was received or June 23, 2004.

On July 13,  2004,  the  Debenture  holders  exercised  all of the July 2003 and
October  2003  Warrants  and  the  Additional  Investment  Rights  amounting  to
approximately $4,198,980 in gross proceeds to the Company. The Company issued to
these holders  warrants  (the "June 2009  Warrants") to purchase an aggregate of
1,300,000 shares of common stock. The issuance of these warrants  resulted in an
additional  debt  discount to the note of  $1,320,000  as explained  below and a
financing charge of $2,351,000.

The June 2009 Warrants are to acquire at any time commencing on January 13, 2005
through  June 30, 2009 an  aggregate  of  1,300,000  shares of common stock at a
price of $3.75 per share.  On July 13, 2005,  the  exercise  price of these June
2009 Warrants will reset to the lesser of the exercise price then in effect or a
price equal to the average of the daily price of the common  stock  between July
14, 2004 and July 12, 2005.  The exercise  price (and the reset price) under the
June 2009 Warrants also is subject to adjustments for  anti-dilution  protection
similar  to those in the other  Warrants.  Notwithstanding  the  foregoing,  the
exercise price as reset or adjusted for anti-dilution,  will in no event be less
than $3.33 per share.  Upon completion of the August 2004 Private Placement (see
below),  the exercise price was lowered to $3.33 per share. This transaction was
subject to a non-cash  financing  charge of $1,320,000 to be amortized  over the
remaining  life of the October 2003  Debentures.  The Company agreed to register
the  shares  issuable  upon  exercise  of the June  2009  Warrants  pursuant  to
substantially the same terms as the registration  rights agreements  between the
Company and the holders. Pursuant to this obligation, the Company has registered
the shares.

On  August  5,  2004,  the  Company  closed  a  private  placement  with  select
institutional  investors of  approximately  3,617,300 shares of its Common Stock
and warrants to purchase an aggregate of up to approximately 1,085,200 shares of
its Common Stock.  Jefferies & Company,  Inc. acted as Placement Agent for which
it received a fee and  warrants to purchase  Common  Stock.  The Company  raised
approximately $6,984,000 net proceeds from this private offering.
The Warrant issued to each purchaser is exercisable  for up to 30% of the number
of shares of Common Stock  purchased  by such  Purchaser,  at an exercise  price
equal to $2.86 per  share.  Each  Warrant  has a term of five years and is fully
exercisable from the date of issuance.

Pursuant to the  Registration  Rights  Agreement,  made and  entered  into as of
August 5, 2004 (the "Rights Agreement"),  the Company has registered the resales
of the shares issued to the Purchasers and shares  issuable upon the exercise of
the Warrants.

Closing  of the  August  2004  Private  Placement  triggered  the  anti-dilution
provisions of the January 2004  Debentures and the July 2004  Debentures and the
July 2009 Warrants and the June 2009 Warrants.  The conversion  price adjustment
for the  Debentures  noted above  resulted in an adjustment of $1,320,000 in the
third quarter 2004 to the Debenture discount and additional paid-in-capital. Any
adjustment to the Debenture  discount will be amortized  over the remaining life
of the Debentures. The exercise price adjustment for the above warrants resulted
in a non-cash financing  adjustment in the third quarter 2004 upon revaluing the
warrants at the new anti-dilution pricing using the Black-Scholes Method.

The March,  July,  October and January 2004  issuances of 6% Senior  Convertible
Debentures in the principal amounts of $5,426,000, $4,142,357 and $4,000,000 and
$2,000,000  respectively and related embedded  conversion  features and warrants
issuances  were  accounted  for in  accordance  with EITF 98-5:  Accounting  for
convertible  securities  with  beneficial  conversion  features  or  contingency
adjustable conversion and with EITF No. 00-27:  Application of issue No. 98-5 to
Certain  convertible  instruments.  The Company determined the fair values to be
ascribed to detachable warrants issued with the convertible debentures utilizing
the Black-Scholes  method.  The Company recorded debt discounts of approximately
$17.4 million which,  in effect,  reduced the carrying value of the debt to $3.6
million.

Pursuant to the terms and conditions of all of the outstanding  Debentures,  the
Company  has  pledged  all of the  Company's  assets,  other than the  Company's
intellectual property, as collateral,  and the Company is subject to comply with
certain financial covenants. As of March 31, 2005, the Company was in compliance
with debt covenants contained within its debenture agreements.

In connection with the Debenture agreements, the Company has outstanding letters
of credit of $1 million as additional collateral.

Note 8: EXECUTIVE COMPENSATION

In order to facilitate the Company's  need to obtain  financing and prior to our
stockholders  approving an amendment  to our  corporate  charter to increase the
number of  authorized  shares,  Dr. Carter agreed to waive his right to exercise
certain  warrants  and  options  unless and until our  stockholders  approved an
increase in our authorized shares of Common Stock.

In October 2003, in recognition of this action as well as Dr. Carter's prior and
on-going  efforts relating to product  development  securing  critically  needed
financing and the acquisition of a new product line, the Compensation  Committee
determined  that Dr. Carter be awarded bonus  compensation in 2003 consisting of
$196,636 and a grant of 1,450,000 stock warrants with an exercise price of $2.20
per share. This additional compensation was reviewed by an independent valuation
firm  and  found  to  be  fair  and  reasonable  within  the  context  of  total
compensation  paid to  chief  executive  officers  of  comparable  biotechnology
companies.

In the quarter ended March 31, 2004, Dr. Carter was awarded an additional  bonus
of $99,481 by the Compensation  Committee.  In addition,  The Company recorded a
non-cash stock  compensation  charge of $1,769,000 during the first quarter 2004
resulting  from  warrants  issued to Dr.  Carter in 2003  that  vested  upon the
execution of the second ISI asset closing on March 17, 2004. This was determined
by subtracting the exercise price from the stock closing price on March 17, 2004
and multiplying the result by the number of warrants.

Note 9 - EQUITY INCENTIVE PLAN

The Equity  Incentive Plan authorizes the grant of  non-qualified  and incentive
stock  options,  stock  appreciation  rights,  restricted  stock and other stock
awards.  The  Equity  Incentive  Plan  provides  for  awards  to be made to such
officers, other key employees,  non-employee directors, consultants and advisors
of the Company and its  subsidiaries  as the board of  directors  may select.  A
maximum of 8,000,000 shares of common stock is reserved for potential  issuance.
Unless sooner terminated,  the Equity Incentive Plan will continue in effect for
a period of 10 years from its effective  date. As of March 31, 2005, the Company
has granted 633,080 options to directors, officers and employees pursuant to the
terms of this plan.

                                    Overview

We  are  a  biopharmaceutical  company  engaged  in  the  clinical  development,
manufacture,  marketing and  distribution  of new drug entities based on natural
immune system enhancing technologies for the treatment of viral and immune based
chronic disorders.  We were founded in the early 1970s, as a contract researcher
for  the  National  Institutes  of  Health.  After  almost  30  years,  we  have
established a strong foundation of laboratory,  pre-clinical,  and clinical data
with  respect  to the  development  of  nucleic  acids to  enhance  the  natural
antiviral  defense  system  of the  human  body  and to aid the  development  of
therapeutic  products  for  the  treatment  of  chronic  diseases.  We own a FDA
approved GMP manufacturing  facility in New Jersey, and our corporate offices in
Philadelphia, PA.

Our flagship products include Ampligen and Alferon.  Ampligen is an experimental
drug    undergoing    clinical    trials   for   the   treatment   of:   Myalgic
Encephalomyelitis/Chronic  Fatigue Syndrome  (ME/CFS),  HIV, and HIV/Hepatitis C
co-infection.  In August 2004, we completed a Phase III clinical  trial treating
over 230 ME/CFS patients with Ampligen and are in the process of preparing a new
drug application to be filed with the FDA. Alferon N Injection is the registered
trademark for our injectable  formulation of Natural Alpha Interferon,  which is
approved by the U.S. Food and Drug  Administration  ("FDA") for the treatment of
genital warts.  Alferon N is also in clinical development for treating Hepatitis
C ("HEP-C"),  Multiple Sclerosis,  Human Immunodeficiency Virus (HIV), West Nile
Virus ("WNV") and Severe Acute Respiratory Syndrome (SARS).

We have over 150 patents worldwide with 14 additional patents pending comprising
our core intellectual property, a fully commercialized product (Alferon),  and a
GMP (good manufacturing practice) certified manufacturing facility.

In March  2004,  we  completed  the  step by step  acquisition  from  Interferon
Sciences,  Inc.  ("ISI") of ISI's  commercial  assets,  Alferon N  inventory,  a
worldwide license for the production,  manufacture,  use,  marketing and sale of
Alferon N. As well as, a 43,000 square foot manufacturing facility in New Jersey
and the acquisition of all intellectual  property related to Alferon.  Alferon N
is a natural alpha  interferon  that has been approved by the FDA for commercial
sale for the  intra-lesional  treatment  of  refractory  or  recurring  external
genital  warts in  patients  18  years  of age or  older.  The  acquisition  was
completed  in Spring  2004 with the  acquisition  of all world  wide  commercial
rights, the FDA approval.

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

Since the  completion of our AMP 516 ME/CFS Phase III clinical  trial for use of
Ampligen(R)  in the  treatment of ME/CFS we have  received  inquiries  from and,
under  confidentiality  agreements,  are having  dialogue  with other  companies
regarding marketing opportunities. No proposals or agreements have resulted from
the dialogue, nor can we be assured that any proposals or agreements will result
from these inquiries.


                                  RISK FACTORS

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

No assurance of successful product development

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

         ALFERON N Injection(R). Although ALFERON N Injection(R) is approved for
marketing in the United States for the intralesional  treatment of refractory or
recurring  external  genital warts in patients 18 years of age or older, to date
it has not been  approved  for  other  indications.  We face  many of the  risks
discussed  above,  with regard to developing this product for use to treat other
ailments such as multiple sclerosis and cancer.

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

         All of our drugs  and  associated  technologies  other  than  ALFERON N
Injection(R) are  investigational  and must receive prior regulatory approval by
appropriate  regulatory  authorities  for general use and are currently  legally
available only through  clinical  trials with specified  disorders.  At present,
ALFERON N  Injection(R)  is only  approved  for the  intralesional  treatment of
refractory  or recurring  external  genital warts in patients 18 years of age or
older.  Use of  ALFERON  N  Injection(R)  for  other  indications  will  require
regulatory  approval.  In this regard,  Interferon  Sciences,  Inc. ("ISI"), the
company from which we obtained our rights to ALFERON N  Injection(R),  conducted
clinical  trials related to use of ALFERON N  Injection(R)  for treatment of HIV
and Hepatitis C. In both instances,  the FDA determined that additional  studies
were necessary in order to fully evaluate the efficacy of ALFERON N Injection(R)
in the  treatment  of HIV and  Hepatitis C diseases.  We have no  obligation  or
immediate plans to conduct these additional studies at this time.

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

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

         We began  operations  in 1966 and last  reported  net profit  from 1985
through 1987. Since 1987, we have incurred  substantial  operating losses, as we
pursued our clinical  trial  effort and  expanded  our efforts in Europe.  As of
March 31, 2005 our accumulated deficit was approximately  $141,000,000.  We have
not  yet  generated  significant  revenues  from  our  products  and  may  incur
substantial  and increased  losses in the future.  We cannot assure that we will
ever achieve  significant  revenues from product sales or become profitable.  We
require, and will continue to require,  the commitment of substantial  resources
to develop our products.  We cannot assure that our product  development efforts
will be  successfully  completed or that required  regulatory  approvals will be
obtained or that any products will be manufactured and marketed successfully, or
be profitable.

We may require additional financing which may not be available.

         The  development  of  our  products  will  require  the  commitment  of
substantial  resources  to  conduct  the  time-consuming  research,  preclinical
development,  and clinical  trials that are  necessary  to bring  pharmaceutical
products to market.  As of March 31, 2005, we had  approximately  $14,407,000 in
cash and cash  equivalents  and  short-term  investments.  These funds should be
sufficient to meet our operating  cash  requirements  including debt service for
the near term. However, we may need to raise additional funds through additional
equity  or debt  financing  or from  other  sources  in  order to  complete  the
necessary clinical trials and the regulatory  approval  processes  including the
commercializing of Ampligen(R) products. There can be no assurances that we will
raise  adequate  funds  from these or other  sources,  which may have a material
adverse effect on our ability to develop our products. Also, we have the ability
to curtail  discretionary  spending,  including  some  research and  development
activities, if required to conserve cash.

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

         We need to preserve and acquire enforceable patents covering the use of
Ampligen(R) for a particular disease in order to obtain exclusive rights for the
commercial  sale of  Ampligen(R)  for such  disease.  We obtained  all rights to
ALFERON N Injection(R),  and we plan to preserve and acquire enforceable patents
covering its use for existing and potentially new diseases. Our success depends,
in large part, on our ability to preserve and obtain patent  protection  for our
products and to obtain and preserve our trade secrets and expertise.  Certain of
our know-how and technology is not patentable,  particularly  the procedures for
the  manufacture of our drug product which are carried out according to standard
operating procedure manuals. We have been issued certain patents including those
on the use of Ampligen(R)  and  Ampligen(R)  in  combination  with certain other
drugs for the  treatment of HIV. We also have been issued  patents on the use of
Ampligen(R) in combination with certain other drugs for the treatment of chronic
Hepatitis  B virus,  chronic  Hepatitis  C virus,  and a  patent  which  affords
protection on the use of Ampligen(R) in patients with Chronic Fatigue  Syndrome.
We have not yet been  issued any  patents  in the  United  States for the use of
Ampligen(R) as a sole treatment for any of the cancers,  which we have sought to
target.  With regard to ALFERON N  Injection(R),  we have  acquired from ISI its
patents  for natural  alpha  interferon  produced  from human  peripheral  blood
leukocytes and its  production  process.  We cannot assure that our  competitors
will not seek and  obtain  patents  regarding  the use of  similar  products  in
combination with various other agents,  for a particular target indication prior
to our doing such.  If we cannot  protect our  patents  covering  the use of our
products for a particular  disease,  or obtain additional patents, we may not be
able to successfully market our products.

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

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


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

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

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

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

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

         We have limited marketing and sales  capability.  We are dependent upon
existing and, possibly future, marketing agreements and third party distribution
agreements for our products in order to generate significant revenues and become
profitable.  As a result,  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 Accredo  offers the  potential to provide some
marketing and  distribution  capacity in the United States while agreements with
Bioclones  (Proprietary),  Ltd,  Biovail  Corporation and  Laboratorios  Del Dr.
Esteve S.A. may provide a sales force in South America,  Africa, United Kingdom,
Australia and New Zealand,  Canada, Spain and Portugal. On December 27, 2004, we
initiated a lawsuit in Federal Court identifying a conspiratorial  group seeking
to illegally  manipulate  our stock for  purposes of bringing  about the hostile
takeover of Hemispherx.  This  conspiratorial  group includes  Bioclones and the
potential legal action may adversely effect our agreement with Bioclones and the
potential for  marketing and  distribution  capacity in South  America,  Africa,
United Kingdom, Australia and New Zealand.

         We cannot assure that our domestic or 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.

There are no long-term  agreements with suppliers of required  materials.  If we
are unable to obtain the  required  raw  materials,  we may be required to scale
back  our  operations  or  stop   manufacturing   ALFERON  N  Injection   and/or
Ampligen(R).

A  number  of  essential  materials  are used in the  production  of  ALFERON  N
Injection(R),  including  human  white  blood  cells.  We do not have  long-term
agreements for the supply of any of such materials. There can be no assurance we
can enter into  long-term  supply  agreements  covering  essential  materials on
commercially reasonable terms, if at all.

         At present,  we do not have any  agreements  with third parties for the
supply of any polymers for use in manufacturing  Ampligen.  We are consolidating
relevant  manufacturing  operations into our New Brunswick,  New Jersey facility
for the production of Ampligen raw materials. This consolidation and transfer of
manufacturing  operations has been  implemented as an inspection of the Ribotech
facility in South Africa,  our previous  supplier of Ampligen(R)  raw materials,
indicated  that it did not, at present,  meet the  necessary GMP standards for a
fully certified  commercial  process.  The transfer of Ampligen(R) raw materials
manufacture to our own facilities,  while having obvious advantages with respect
to  regulatory  compliance  (other  parts of the  43,000 sq.  ft.  wholly  owned
facility are already in compliance for Alferon N manufacture), may delay certain
steps in the commercialization process, specifically a targeted NDA filing.

         If we are  unable to  obtain  the  required  raw  materials,  we may be
required  to scale  back our  operations  or stop  manufacturing.  The costs and
availability of products and materials we need for the production of Ampligen(R)
and the commercial production of ALFERON N Injection(R) and other products which
we may commercially produce are subject to fluctuation depending on a variety of
factors  beyond  our  control,   including   competitive  factors,   changes  in
technology,  and FDA and  other  governmental  regulations  and  there can be no
assurance  that we will be able to obtain such  products and  materials on terms
acceptable to us or at all.

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

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

We have limited manufacturing experience and capacity.

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

         In  connection   with  settling   various   manufacturing   infractions
previously  noted  by  the  FDA,  Schering-Plough  ("Schering")  entered  into a
"Consent  Decree"  with the FDA  whereby,  among  other  things,  it  agreed  to
discontinue various contract (third party)  manufacturing  activities at various
facilities  including its San Juan, Puerto Rico, plant.  Ampligen(R)  (which was
not involved in any of the cited  infractions)  was produced at this Puerto Rico
plant from year 2000-2004. Operating under instructions from the Consent Decree,
Schering has advised us that it would no longer manufacture  Ampligen(R) in this
facility  beyond  2004  and  would  assist  us in an  orderly  transfer  of said
activities to other non Schering facilities. Accordingly, we have entered into a
Confidentiality  Agreement  with Mayne  Pharma  Pty,  Ltd  ("Mayne")  to lead to
reinitiation  and expansion of its  Ampligen(R)  manufacturing  program.  We are
currently  in   discussions   with  Mayne  to  provide  us  with   proposals  on
manufacturing  Ampligen(R) at their facility.  Mayne (formerly known as Faulding
Pharma) has already  successfully  manufactured  Ampligen(R)  several  times for
ongoing  clinical  trials,  and  maintains  a  fully  GMP  compliant   facility.
Simultaneously, we expect to qualify at least one other GMP facility to maintain
a minimum of two independent  production sites. If we are unable to engage Mayne
and/or additional manufacturers in a timely manner, our plans to file an NDA for
Ampligen(R) and, eventually, to market and sell Ampligen(R) will be delayed.

         The purified drug concentrate  utilized in the formulation of ALFERON N
Injection(R)  is  manufactured  in our New  Brunswick,  New Jersey  facility and
ALFERON N  Injection(R)  was  formulated  and packaged at a production  facility
formerly  owned and operated by Abbott  Laboratories  located in Kansas.  Abbott
Labs has sold the facility to Hospira and we are currently in  discussions  with
two other production facilities for this work. We currently have 12,000 vials at
Hospira in purified drug  concentrate  form. We are negotiating  with Hospira to
complete  the  labeling  and  packaging  of this lot.  If  Hospira  is unable to
complete this production,  or if we are unable to secure a new facility within a
reasonable  period of time to formulate and package ALFERON N Injection(R) at an
acceptable  cost,  our ability to sell  ALFERON N  Injection(R)  and to generate
profits therefrom will be adversely affected.

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

         We have  never  produced  Ampligen(R)  or any other  products  in large
commercial  quantities.  We must  manufacture  our products in  compliance  with
regulatory  requirements in large commercial  quantities and at acceptable costs
in order for us to be profitable. We intend to utilize third-party manufacturers
and/or  facilities if and when the need arises or, if we are unable to do so, to
build  or  acquire  commercial-scale  manufacturing  facilities.  If  we  cannot
manufacture  commercial  quantities  of  Ampligen(R)  or enter into third  party
agreements for its manufacture at costs acceptable to us, our operations will be
significantly  affected.  Also, each production lot of Alferon N Injection(R) is
subject to FDA review and approval prior to releasing the lots to be sold.  This
review and approval process could take considerable  time, which would delay our
having  product in inventory to sell.  Alferon N  Injection(R)  presently  has a
shelf life of 18 months after  having been  bottled.  Studies were  completed in
2004 to possibly extend the shelf life to 24 months.  We filed our annual report
with the FDA in December 2004  informing them of the extension of shelf-life for
Alferon N Injection(R). We filed the request with the FDA in May 2005 requesting
approval to relabel the first  2,000  vials with an  extended  shelf-life  of 24
months. We anticipate a response from the FDA by the end of June 2005.

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

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

Our products may be subject to substantial competition.

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

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

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

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

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

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

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

         We face an inherent  business  risk of  exposure  to product  liability
claims in the event that the use of Ampligen(R) or other of our products results
in adverse  effects.  This  liability  might result from claims made directly by
patients,  hospitals, clinics or other consumers, or by pharmaceutical companies
or others  manufacturing these products on our behalf. Our future operations may
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 appropriate  precautions,  we cannot assure that we will avoid  significant
product  liability  exposure.  Although we currently  maintain product liability
insurance  coverage,  there can be no assurance that this insurance will provide
adequate  coverage against Ampligen and/or Alferon N Injection product liability
claims. A successful  product liability claim against us in excess of Ampligen's
$1,000,000  in insurance  coverage;  $3,000,000  in  aggregate,  or in excess of
Alferon's  $5,000,000 in insurance  coverage;  $5,000,000  in aggregate;  or for
which coverage is not provided could have a negative  effect on our business and
financial condition.

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

         Our success is dependent  on the  continued  efforts of Dr.  William A.
Carter  because of his position as a pioneer in the field of nucleic acid drugs,
his being the  co-inventor  of  Ampligen(R),  and his  knowledge  of our overall
activities,  including  patents and clinical  trials.  The loss of Dr.  Carter's
services could have a material  adverse effect on our operations and chances for
success.  We have secured key man life  insurance in the amount of $2,000,000 on
the life of Dr. Carter and we have an employment agreement with Dr. Carter that,
as  amended,  runs  until May 8,  2008.  However,  Dr.  Carter  has the right to
terminate his employment  upon not less than 30 days prior written  notice.  The
loss of Dr.  Carter or other  personnel,  or the  failure to recruit  additional
personnel  as needed could have a  materially  adverse  effect on our ability to
achieve our objectives.

Uncertainty of health care reimbursement for our products.

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

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

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

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

         The  market  price of our  common  stock  has been and is  likely to be
volatile. In addition to general economic,  political and market conditions, the
price and trading volume of our stock could fluctuate widely in response to many
factors, including:

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

o  adverse reactions to products;

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

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

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

o  announcements of technological innovations by us or our competitors;

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

o  actual or anticipated  variations in our operating results due to the level
   of development expenses and other factors; o changes in financial estimates
   by  securities  analysts  and  whether  our  earnings  meet or  exceed  the
   estimates;

o  conditions  and  trends  in  the  pharmaceutical  and  other
   industries; new accounting standards; and

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

         Our  common  stock  is  listed  for  quotation  on the  American  Stock
Exchange.  For the 12-month period ended March 31, 2005, the price of our common
stock has  ranged  from  $1.50 to $5.40 per  share.  We expect  the price of our
common stock to remain volatile.  The average daily trading volume of our common
stock varies  significantly.  Our  relatively low average volume and low average
number of  transactions  per day may affect the ability of our  stockholders  to
sell their shares in the public  market at  prevailing  prices and a more active
market may never develop.

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

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

         As of April 25, 2005, approximately 544,572 shares of our common stock,
constituted  "restricted securities" as defined in Rule 144 under the Securities
Act of 1933. 179,323 of these shares have been registered pursuant to agreements
between us and the holders of these  shares.  In  addition,  we have  registered
9,352,765  shares  issuable (i) upon  conversion  of  approximately  135% of the
January 2004 Debentures,  the October 2003 Debentures,  the July 2003 Debentures
and the July 2004 Debentures;  (ii) as payment of 135% of the interest on all of
the Debentures;  (iii) upon exercise of 135% of the July 2009 Warrants issued in
conjunction with the January 2004 Debentures, the May 2009 Warrants and the June
2009 Warrants; and (iv) upon exercise of certain other warrants. Registration of
the shares  permits  the sale of the shares in the open  market or in  privately
negotiated transactions without compliance with the requirements of Rule 144. To
the extent the  exercise  price of the warrants is less than the market price of
the common  stock,  the holders of the warrants are likely to exercise  them and
sell the underlying shares of common stock and to the extent that the conversion
price  and  exercise  price  of  these  securities  are  adjusted   pursuant  to
anti-dilution protection, the securities could be exercisable or convertible for
even more shares of common  stock.  We also may issue  shares to be used to meet
our capital  requirements  or use shares to  compensate  employees,  consultants
and/or  directors.  We are unable to estimate  the  amount,  timing or nature of
future sales of outstanding  common stock.  Sales of substantial  amounts of our
common  stock in the public  market  could cause the market price for our common
stock to decrease. Furthermore, a decline in the price of our common stock would
likely  impede our ability to raise  capital  through the issuance of additional
shares of common stock or other equity securities.

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

         Provisions of our  Certificate  of  Incorporation  and Delaware law may
make  it  more  difficult  for  someone  to  acquire  control  of us or for  our
stockholders to remove existing  management,  and might discourage a third party
from offering to acquire us, even if a change in control or in management  would
be beneficial to our stockholders. For example, our Certificate of Incorporation
allows us to issue shares of preferred  stock without any vote or further action
by our  stockholders.  Our  Board  of  Directors  has the  authority  to fix and
determine the relative rights and preferences of preferred  stock.  Our Board of
Directors  also has the  authority  to issue  preferred  stock  without  further
stockholder  approval.  As a result,  our Board of Directors could authorize the
issuance  of a series  of  preferred  stock  that  would  grant to  holders  the
preferred right to our assets upon  liquidation,  the right to receive  dividend
payments before dividends are distributed to the holders of common stock and the
right to the  redemption of the shares,  together  with a premium,  prior to the
redemption of our common stock.  In this regard,  in November 2002, we adopted a
stockholder  rights plan and, under the Plan, our Board of Directors  declared a
dividend distribution of one Right for each outstanding share of Common Stock to
stockholders of record at the close of business on November 29, 2002. Each Right
initially  entitles  holders to buy one unit of preferred stock for $30.00.  The
Rights generally are not  transferable  apart from the common stock and will not
be exercisable unless and until a person or group acquires or commences a tender
or exchange offer to acquire,  beneficial ownership of 15% or more of our common
stock.  However,  for Dr.  Carter,  our chief  executive  officer,  who  already
beneficially  owns 10.9% of our common stock,  the Plan's threshold will be 20%,
instead of 15%. The Rights will expire on November 19, 2012, and may be redeemed
prior thereto at $.01 per Right under certain circumstances.

         Because the risk factors  referred to above could cause actual  results
or outcomes to differ  materially  from those  expressed in any  forward-looking
statements  made  by us,  you  should  not  place  undue  reliance  on any  such
forward-looking  statements.  Further, any forward-looking statement speaks only
as of the date on which it is made and we undertake no  obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the  date on  which  such  statement  is  made  or  reflect  the  occurrence  of
unanticipated  events.  New  factors  emerge  from  time to time,  and it is not
possible for us to predict which will arise.  In addition,  we cannot assess the
impact of each  factor on our  business  or the extent to which any  factor,  or
combination of factors, may cause actual results to differ materially from those
contained in any  forward-looking  statements.  Our research in clinical efforts
may continue for the next several  years and we may continue to incur losses due
to clinical  costs incurred in the  development  of  Ampligen(R)  for commercial
application.  Possible  losses may fluctuate from quarter to quarter as a result
of  differences in the timing of  significant  expenses  incurred and receipt of
licensing fees and/or cost recovery treatment revenues in Europe,  Canada and in
the United States.

                          NEW ACCOUNTING PRONOUNCEMENTS

         In December  2004,  the  Financial  Accounting  Standards  Board (FASB)
issued Statement of Financial  Accounting Standards No. 123 (revised 2004) (FASB
123R),  Shared-Based  Payment. FASB 123R will require the Corporation to expense
share-based  payments,  including  employee stock  options,  based on their fair
value.  The  Corporation  is  required  to adopt  the  provisions  of FASB  123R
effective as of the beginning of its next fiscal year that begins after June 15,
2005.  FASB  123R  provides  alternative  methods  of  adoption,  which  include
prospective application and a modified retroactive application.  The Corporation
is  currently   evaluating  the  financial   impact,   including  the  available
alternative of adoption of FASB 123R.

Disclosure About Off-Balance Sheet Arrangements

         Prior to our annual meeting of stockholders in September 2003, we had a
limited  number of shares of Common Stock  authorized but not issued or reserved
for  issuance  upon  conversion  or  exercise  of  outstanding  convertible  and
exercisable  securities such as debentures,  options and warrants.  Prior to the
meeting,  to permit consummation of the sale of the July 2003 Debentures and the
related  warrants,  Dr. Carter agreed that he would not exercise his warrants or
options unless and until our stockholders  approve an increase in our authorized
shares of common stock. For Dr. Carter's waiver of his right to exercise certain
options and warrants prior to approval of the increase in our authorized shares,
we  have  agreed  to  compensate  Dr.  Carter.  See  Note 8 in the  accompanying
financial statements for more information concerning this transaction.
In connection  with the Debenture  agreements,  we have  outstanding  letters of
credit of $1,000,000 as additional collateral.

Critical Accounting Policies

         Financial  Reporting Release No. 60 requires all companies to include a
discussion of critical accounting policies or methods used in the preparation of
financial statements. Our significant accounting policies are described in Notes
to the Consolidated  Financial Statements.  The significant  accounting policies
that we believe are most  critical to aid in fully  understanding  our  reported
financial results are the following:

Revenue

         Revenues  for  non-refundable  license  fees are  recognized  under the
Performance  Method-Expected  Revenue. This method considers the total amount of
expected revenue during the performance period, but limits the amount of revenue
recognized  in a period to total  non-refundable  cash  received  to date.  This
limitation is appropriate  because future  milestone  payments are contingent on
future events.

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

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

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

         Revenues  from the sale of product are  recognized  when the product is
shipped,  as title is transferred to the customer.  We have no other  obligation
associated with our products once shipment has occurred.

Patents and Trademarks

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

Concentration of Credit Risk

         Financial  instruments  that  potentially  subject  us to credit  risks
consist of cash equivalents and accounts receivable.

         Our  policy  is to limit  the  amount  of  credit  exposure  to any one
financial   institution  and  place  investments  with  financial   institutions
evaluated as being credit  worthy,  or in short-term  money  markets,  which are
exposed  to  minimal  interest  rate and credit  risks.  At times,  we have bank
deposits and  overnight  repurchase  agreements  that exceed  federally  insured
limits.

         Concentration  of credit risk, with respect to receivables,  is limited
through  our credit  evaluation  process.  We do not require  collateral  on our
receivables.  Our receivables  consist principally of amounts due from wholesale
drug companies as of March 31, 2005.
RESULTS OF OPERATIONS

Three months ended March 31, 2005 versus Three months ended March 31, 2004

Net loss

     Our net loss of  $3,055,000  for the three  months ended March 31, 2005 was
down  $4,987,000  or 62%  compared  to the  same  period  in  2004.  90% of this
reduction  or  $4,531,000  was due to 1) lower costs  associated  with  non-cash
financing charges related to convertible  debentures and 2) lower non-cash stock
compensation  expenses.  Production/cost  of goods sold costs were down $503,000
primarily due to  expenditures  in the first quarter of 2004 associated with the
ramping up of the New  Brunswick  facility for further  production  of Alferon N
Injection(R).  Net losses per share were $(.07) for current period versus $(.20)
in the same period 2004.

Revenues

         Revenues  for the three  months  ended March 31, 2005 were  $258,000 as
compared  to revenues of  $308,000  for the same period in 2004.  Ampligen  sold
under the cost  recovery  clinical  program was down $20,000 (41%) and Alferon N
Injection  sales were down $30,000 (12%).  Ampligen sold under the cost recovery
clinical program is a product of physicians and ME/CFS patients  applying to the
Company to enroll in the  program.  After  screening  the  patient's  enrollment
records,  the  Company  ships  Ampligen  to the  physician.  A typical six month
treatment therapy costs the patient about $7,200 for Ampligen.  This program has
been in effect for many years and is offered as a  treatment  option to patients
severely  affected by ME/CFS.  As the name "cost recovery"  implies,  we have no
gain or profit on these  sales.  The  benefits to us include 1)  physicians  and
patient's  becoming  familiar  with  Ampligen and 2) collection of clinical data
relating to the patient's treatment and results.

         Alferon N sales are anticipated to increase as we are in the process of
establishing an internal marketing and sales infrastructure to support the sales
of Alferon N  Injection  in the United  States,  including  marketing  and sales
support  professionals based at our headquarters in Philadelphia,  Pennsylvania.
We have hired and  trained our two  regional  sales  managers  and have hired an
additional  sales manager in April 2005. We will continue to  aggressively  hire
and train more sales  representatives  in the  expertise  in this field.  We are
targeting sales representatives with an average of 6-8 years of experience.  Our
sales  force  will   introduce   Alferon  and  promote   Alferon  to  OB  GYN's,
dermatologists,  and infectious disease physicians and particularly STD Clinics,
who are  involved in the  treatment  of patients  with  refractory  or recurring
external  genital warts, as well as physicians about the growing problem and the
risks of HPV. In addition to marketing  and sales  personnel,  we have hired The
Schwartz Group, a telemarketing group. The Schwartz Group is a marketing partner
organization  that works exclusively with companies selling products or services
to Physicians,  Hospitals,  and Retail  Pharmacies.  They perform  telemarketing
campaigns  that are designed to assist their  clients and expand their reach and
market  share.  We expect to use their leads to assist our sales force in making
sales calls.

         We  also   intend  to  expand  our   marketing/sales   programs  on  an
international  basis with our  primary  focus on Europe.  This  program is being
designed to engage European pharmaceutical distributors to market and distribute
Alferon N.

         Human papillomavirus (HPV) is one of the most common causes of sexually
transmitted  infection in the world.  Experts estimate that there are more cases
of genital HPV infection than of any other sexually transmitted disease (STD) in
the United States. The Centers for Disease Control and the National Institute of
Health,  report that approximately 20 million people are presently infected with
HPV.  At least one half of  sexually  active men and women  acquire  genital HPV
infection at some point in their lives.  By age 50, at least 80 percent of women
will have gotten a genital HPV  infection.  Roughly 6.2 million  Americans get a
new genital HPV infection each year. The potential market for drugs treating HPV
is extremely large.

Production costs/cost of goods sold

         Production  costs  for the  three  months  ended  March  31,  2004 were
$490,000. These costs represented expenditures associated with preparing the New
Brunswick facility for further production of Alferon N Injection(R) in the first
quarter  2004.  There were no  production  costs for Alferon N Injection  in the
current quarter as we concentrated on the completion of the consolidation of all
manufacturing  and  research  and  development  activities  within  our own Good
Manufacturing  Practice  (GMP)  Facility in New  Brunswick  for  Ampligen.  This
consolidation  will improve  efficiency and compliance  procedures and bring the
facility in line with worldwide drug manufacturing standards.

         Cost of goods sold for the three  months  ended March 31, 2005 and 2004
were  $98,000  and  $111,000,   respectively.   Since  acquiring  the  right  to
manufacture  and  market  Alferon  N on  March  11,  2003,  we have  focused  on
converting   the   work-in-progress   inventory   into  finished   goods.   This
work-in-progress   inventory   included  three   production  lots  totaling  the
equivalent  of  approximately  55,000  vials  (doses) at  various  stages of the
manufacturing process.  Approximately 34,000 vials have been produced. In August
2004, we released most of the second lot of product to Hospira  (formerly Abbott
Laboratories) for bottling and realized approximately 12,000 vials of Alferon N.
Some 3,000 of the remaining  vials within this lot were held back to be utilized
in the development of a more compatible vial size for manufacturing of Alferon N
Injection.  We have had  preliminary  discussions  with  Hospira to complete the
labeling  and  packaging  of  our  approximately   12,000  vials  of  Alferon  N
Injection(R)  at their site.  If Hospira  will not  complete  the  labeling  and
packaging or if we are unable to secure a new facility to formulate  and package
Alferon N  Injection(R)  at an  acceptable  cost,  our ability to sell Alferon N
Injection(R) and to generate profits therefrom will be adversely affected.

         We plan on  initiating  the  process  of  converting  the  third lot of
approximately 13,000 vials from  work-in-progress to finished goods inventory in
the second  half of 2005.  Approximately  2,000 vials were  abstracted  from the
third lot for research and development purposes during the 4th quarter 2004. Our
production and quality control  personnel in our New Brunswick,  NJ facility are
involved in the extensive  process of manufacturing  and validation  required by
the FDA. We are  currently in  discussions  with two  production  facilities  to
formulate,  bottle,  package and label Alferon N Injection(R) on a going forward
basis.

         We completed the  consolidation of our Rockville  Quality Assurance Lab
and equipment into our New Brunswick facility.  This consolidation of facilities
will produce savings in facility and manpower costs.

Research and Development costs

         Overall  research  and  development  direct  costs for the three months
ended March 31, 2005 and 2004 were $1,268,000 and $964,000,  respectively. These
costs in 2005 reflect the direct costs associated with our effort to develop our
lead product, Ampligen(R), as a therapy in treating chronic diseases and cancers
as well as on-going  clinical trials  involving  patients with HIV. In addition,
these costs reflect direct costs incurred relating to the development of Alferon
LDO (low dose oral). We have over approximately 161,000 doses on hand of Alferon
LDO which  have been  prepared  for use in  clinical  trials  treating  patients
affected with the SARS or other potentially emerging infectious  diseases,  such
as, avian flu.

         In the three months ended March 31, 2005 we have increased our clinical
staff by employing  additional  medical doctors,  a PhD and several other highly
trained  individuals to focus on the preparation of our Ampligen NDA filing.  We
are being  meticulous in the  preparation of the NDA. Our clinical  monitors and
research  assistants are in the process of visiting the multiple  clinical study
sites  around the country and are  collecting  data  generated  at each of these
sites. All data must be reviewed and checked to clarify any  inconsistencies  or
inaccuracies  that turn up. Due to the human  factor,  these  types of  problems
occur in all clinical  trials.  These gaps and  inconsistencies  in data must be
resolved with the respective clinical  investigators,  while maintaining a clear
record of events  which  allows the FDA to conduct a  meaningful  audit of these
records.

         We  believe  that our  recently  completed  AMP 516  ME/CFS  Phase  III
clinical  trial for use of  Ampligen(R)  in the  treatment of ME/CFS is the most
comprehensive  study ever  conducted in ME/CFS.  This Phase III clinical  trial,
which was conducted over a six year period,  involved an enrollment of more than
230  severely  debilitated  CFS patients  and was  conducted  at twelve  medical
centers  throughout the United States.  The study is serving as the basis for us
to file a new drug  application  with the FDA. As discussed above, we have hired
additional  personnel  and in the process of  preparing  the NDA. The FDA review
process  could take 18-24 months and result in one of the following  events;  1)
approval to market  Ampligen(R) for use in treating ME/CFS patients,  2) require
more research,  development, and clinical work, 3) approval to market as well as
conduct more testing,  or 4) reject our application.  Given these variables,  we
are unable to project  when  material  net cash inflows are expected to commence
from the sale of Ampligen(R).

         We had  originally  targeted a late 2004  filing date for this new drug
application  for  Ampligen(R).  In order to  respond  to recent  changes  in the
regulatory  environment that place a greater emphasis on the safety and efficacy
of all new  experimental  drug  candidates,  we are now  incorporating  a larger
sample of data from our  previous  trials.  The NDA filing will now include data
accumulated from 40,000 administrations of the studied drug to approximately 700
CFS patients.

         At the 18th International Conference on Antiviral Research on April 10,
2005, we presented new  peer-reviewed  data entitled  "Correlation  of Increased
Oxygen Consumption with Enhanced Treadmill  Performance in Patients with Chronic
Fatigue  Syndrome  (CFS) as a  Function  of  Ampligen(R)".  According  to recent
reports by the Centers  for Disease  Control and  Prevention  (CDC),  ME/CFS,  a
disease that affects between 400,000 and 800,000 Americans, is more serious than
multiple  sclerosis with respect to medical severity and overall economic impact
on society.  This was  reported in the ME/CFS  Advisory  Committee  Report dated
January 5, 2005. Specifically, ME/CFS imparts a clinically significant, profound
deficit in oxygen  utilization  to  patients,  which  impairs  their  ability to
perform a range of ambulatory  functions  necessary to maintain quality of life.
Similar oxygen consumption deficits have been observed in other chronic diseases
such as congestive heart failure/angina ("CHF") and chronic pulmonary conditions
such as pulmonary arterial  hypertension  ("PAH") both of which now have a range
of  readily   available,   commercially   approved,   therapeutics  for  disease
intervention.

         The  experimental  Ampligen(R)  treatment in ME/CFS  improved  exercise
duration  up to two times more than  approved  (or  approvable)  drugs for their
respective  chronic disease  indications.  Ampligen(R)  increased the percentage
improvement in endurance (as  determined by an "intent to treat"  analysis) more
than 15% over the placebo group. In the ME/CFS study, maximal oxygen consumption
(VO2max)  increased  ten  fold  with  Ampligen  vs.  Placebo.  There  was a high
correlation  between improvement in exercise duration and increase in VO2 max (p
is less than  0.0001).  VO2max is a measure  of oxygen  consumption  at  maximum
exertion.

         By  comparison,  analysis  of  seven  recent  clinical  studies,  which
resulted in  commercial  approvals (or  "approvable"  letters) for various drugs
used in these other allied disease  categories  (both CHF and PAH),  showed much
lower  magnitudes  of  physical  performance  improvements  due  to  therapeutic
interventions.  For example, in CHF:  Fosinopril (6.7%  improvement),  Captopril
(6.2%),  Ranolazine  (6.5%)  and  Ranolazine  (5.7%);  in PAM,  Tracleer  (10.6%
improvement),   Remodulin  (8.0%),   and  Remodulin   (4.1%).   All  therapeutic
measurements in these seven other studies were determined by exercise  treadmill
testing (or extent of walking), similar or identical to the therapeutic endpoint
used in the CFS study.

         With respect to Ampligen(R) in the ME/CFS pivotal study, no significant
differences (p>0.05) were observed between the two groups (drug vs. placebo) for
treatment dropouts, the incidence of serious adverse events, or missed treatment
doses.  With respect to relative safety of the experimental  therapeutic,  there
were also no significant differences in week forty blood chemistry,  hematology,
or thyroid function parameters. These results are consistent with two prior open
label  trials and a phase II,  double-blind,  placebo  controlled,  multi-center
clinical trial of Ampligen(R).

         Ampligen is also  currently in two Phase IIb studies for the  treatment
of HIV to overcome multi-drug resistance, virus mutation and toxicity associated
with current HAART  therapies.  One study,  the AMP-719,  is a Salvage  Therapy,
conducted in the U.S.  and  evaluating  the  potential  synergistic  efficacy of
Ampligen in multi-drug resistant HIV patients for immune enhancement. The second
study,  the  AMP-720,  is a clinical  trial  designed to evaluate  the effect of
Ampligen under  Strategic  Treatment  Intervention  and is also conducted in the
U.S.  Enrollment  in the AMP 719  study is  presently  on hold as we  focus  our
efforts on ramping up the AMP 720 study.

         We have recruited and hired additional  clinical research associates to
assist  in the  recruitment  of  clinical  investigators  and  HIV  patients  to
participate in the AMP 720 HIV clinical  trial.  The AMP 516 ME/CFS is completed
and we are devoting more resources toward the AMP 720 HIV clinical trial.

         The  Amp 720 HIV  study  is a  treatment  using a  Strategic  Treatment
Interruption  (STI). The patients'  antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as mono-immunotherapy. Ampligen(R) is an experimental
immunotherapeutic  designed  to display  both  antiviral  and  immune  enhancing
characteristics.  Prolonged use of Highly Active Antiretroviral  Therapy (HAART)
has been associated with long-term,  potentially fatal, toxicities. The clinical
study  AMP  720  is  designed  to  address  these  issues  by   evaluating   the
administration of our lead experimental  agent,  Ampligen(R),  a double stranded
RNA drug acting potentially both as an immunomodulator and antiviral.  Patients,
who have  completed at least nine months of  Ampligen(R)  therapy,  were able to
stay off HAART for a total STI duration  with a mean time of 29.0 weeks  whereas
the control group,  which was also taken off HAART,  but not given  Ampligen(R),
had earlier HIV rebound with a mean  duration of 18.7 weeks.  Thus,  on average,
Ampligen(R)  therapy spared the patients  excessive  exposure to HAART, with its
inherent  toxicities,  for more than 11 weeks. As of April 28, 2005 we have five
clinical investigators on board treating five HIV patients. 41 HIV patients have
already  participated  in this 64 week study.  It is  difficult  to estimate the
duration or projected  costs of this  clinical  trial due to the many  variables
involved,  i.e.: patient drop out rate,  recruitment of clinical  investigators,
etc. The length of the study and costs related to our clinical  trials cannot be
determined at this time as such will be materially  influenced by (a) the number
of clinical  investigators  needed to recruit and treat the  required  number of
patients,  (b) the rate of accrual of patients and (c) the retention of patients
in the studies and their  adherence to the study  protocol  requirements.  Under
optimal  conditions,  the cost of completing the studies could be  approximately
$2.5 to $3.0  million if the target of 120  patients  is  achieved.  The rate of
enrollment  depends  on  patient  availability  and on other  products  being in
clinical  trials for the treatment of HIV, as there is competition  for the same
patient  population.  At  present,  more  than  18 FDA  approved  drugs  for HIV
treatment may compete for available  patients.  The length, and subsequently the
expense of these studies,  will also be determined by an analysis of the interim
data,  which  will  determine  when  completion  of  the  ongoing  Phase  IIb is
appropriate  and whether a Phase III trial will be  conducted  or not. In case a
Phase  III  study is  required;  the FDA  might  require  a  patient  population
exceeding  the current one which will  influence the cost and time of the trial.
Accordingly,  the number of  "unknowns"  is  sufficiently  great to be unable to
predict  when,  or  whether,  we may  obtain  revenues  from  our HIV  treatment
indications.

         A clinical  study has been  approved by the  Clinical  Research  Ethics
Committee of the Kowloon West Cluster at the Princess  Margaret Hospital in Hong
Kong to evaluate the use of Alferon(R)  LDO (Low Dose Oral  Interferon  Alfa-N3,
Human Leukocyte Derived) in normal volunteers and/or asymptomatic  subjects with
exposure to a person known to have Severe Acute Respiratory Syndrome (SARS).

         The trial methodology may have implications for treating other emerging
viruses  such as avian  influenza  (bird flu).  Present  production  methods for
vaccines  involve  the use of  millions  of  chicken  eggs and  would be slow to
respond  to  an  outbreak   according  to  a  recently   convened  World  Health
Organization  (WHO) expert panel in November  2004.  Health  officials  are also
concerned  that bird flu could  mutate to cause  the next  pandemic  and  render
present  vaccines  under  development  ineffective.  We have  prepared more than
300,000 doses of Alferon LDO for appropriate clinical programs.

         In  September  2004,  we  commenced a clinical  trial  using  Alferon N
Injection to treat  patients  infected with the West Nile Virus.  The infectious
Disease  section of New York Queens  Hospital and the Weill  Medical  College of
Cornell  University will be conducting this  double-blinded,  placebo controlled
trial. During 2004, over 2,000 human cases of West Nile Virus have been reported
in 40 states.

         In  order  to  obtain  Ampligen(R)  raw  materials  on a  more  regular
production  basis,  we  implemented   consolidation  and  transfer  of  relevant
manufacturing  operations into our New Brunswick, New Jersey facility during the
first quarter 2005. This consolidation and transfer of manufacturing  operations
has been  implemented as a recent  inspection of the Ribotech  facility in South
Africa,  our previous  supplier of Ampligen(R) raw materials,  indicated that it
did  not,  at  present,  meet  the  necessary  standards  for a fully  certified
commercial process. The transfer of Ampligen(R) raw materials manufacture to our
own facilities  has obvious  advantages  with respect to overall  control of the
manufacturing  procedure of  Ampligen's  raw  materials,  keeping costs down and
controlling  regulatory  compliance  issues  (other  parts of the 35,725 sq. ft.
wholly owned  facility are FDA  approved  for Alferon N  manufacture).  This may
delay certain steps in the  commercialization  process,  specifically a targeted
NDA filing.

         In  connection   with  settling   various   manufacturing   infractions
previously  noted  by  the  FDA,  Schering-Plough  ("Schering")  entered  into a
"Consent  Decree"  with the FDA  whereby,  among  other  things,  it  agreed  to
discontinue various contract (third party)  manufacturing  activities at various
facilities  including its San Juan, Puerto Rico, plant.  Ampligen(R)  (which was
not involved in any of the cited  infractions)  was produced at this Puerto Rico
plant from year 2000-2004. Operating under instructions from the Consent Decree,
Schering has recently advised us that it would no longer manufacture Ampligen(R)
in this facility at the end of the  applicable  term (which is 4th quarter 2004)
and would  assist us in an  orderly  transfer  of said  activities  to other non
Schering  facilities.  Accordingly,  we  have  entered  into  a  Confidentiality
Agreement  with Mayne Pharma Pty,  Ltd  ("Mayne")  to lead to  reinitiation  and
expansion  of  its  Ampligen(R)  manufacturing  program.  We  are  currently  in
discussions with Mayne to provide us with proposals on manufacturing Ampligen(R)
at their  facility.  Mayne  (formerly  known as  Faulding  Pharma)  has  already
successfully manufactured Ampligen(R) several times for ongoing clinical trials,
and  maintains  a fully GMP  compliant  facility.  Simultaneously,  we expect to
qualify at least one other GMP facility to maintain a minimum of two independent
production   sites.  If  we  are  unable  to  engage  Mayne  and/or   additional
manufacturers in a timely manner,  our plans to file an NDA for Ampligen(R) and,
eventually, to market and sell Ampligen(R) will be delayed.
General and Administrative Expenses

         General and Administrative  ("G&A") expenses for the three months ended
March  31,  2005  and  2004  were   approximately   $982,000   and   $2,844,000,
respectively.  The decrease in G&A expenses of $1,862,000  during this period is
primarily due to a non-cash stock  compensation  charge of $1,769,000  resulting
from the  issuance of 1,450,000  warrants to purchase  common stock at $2.20 per
share to Dr. Carter in 2003 that vested in the first quarter 2004.  The warrants
vested  upon the second ISI asset  closing  which  occurred  on March 17,  2004.
Please  see "Item 11.  Executive  Compensation."  contained  within our Form 10K
filed with the  Securities  and Exchange  Commission on March 16, 2005, for more
details on how Dr. Carter was compensated. In addition,  investment banking fees
relating to  assistance  in  financial  matters and public  relations  fees also
contributed to the decrease in G&A expenses from period-to-period.

Interest and Other Income

         Interest and other income for the three months ended March 31, 2005 and
2004 totaled  $230,000 and $11,000,  respectively.  The increase in interest and
other  income  during the current  quarter can  primarily be  attributed  to the
maturing of marketable securities during the 2005 period. All funds in excess of
our immediate need are invested in short-term high quality securities.

Interest Expense and Financing Costs

         Non-cash  financing  costs were  $1,089,000  for the three months ended
March 31, 2005 versus  $3,851,000 for the same three months a year ago. Non-cash
financing  costs consist of the  amortization  of debenture  closing costs,  the
amortization  of  Original  Issue  Discounts  and  the   amortization  of  costs
associated  with beneficial  conversion  features of our debentures and the fair
value of the warrants relating to the Debentures. These charges are reflected in
the Consolidated  Statements of Operations under the caption  "Financing Costs."
These charges are amortized over the life of the debentures. The aggregate total
of these  charges  have been  reduced  since the  first  quarter  of 2004 due to
amortization  charges,  as well as,  charges  related to the  conversion  of the
debentures.  Also,  in connection  with the  redemption  obligation  recorded in
conjunction with the January 2004 Debenture,  we recorded  additional  financing
costs of approximately  $947,000 in the first quarter 2004. Please see Note 7 in
the consolidated financial statements contained herein for more details on these
transactions.

Liquidity And Capital Resources

         Cash used in operating  activities for the three months ended March 31,
2005 was $2,052,000.  There was no cash provided by financing activities for the
three months ended March 31, 2005.  As of March 31, 2005,  we had  approximately
$14,407,000  million in cash and short-term  investments.  These funds should be
sufficient to meet our operating  cash  requirements  including debt service for
the near term. However, we may need to raise additional funds through additional
equity  or debt  financing  or from  other  sources  in  order to  complete  the
necessary clinical trials and the regulatory  approval  processes  including the
commercializing of Ampligen(R) products. There can be no assurances that we will
raise  adequate  funds  from these or other  sources,  which may have a material
adverse effect on our ability to develop our products. Also, we have the ability
to curtail  discretionary  spending,  including  some  research and  development
activities, if required to conserve cash.

         Please see Note 7 - "Debenture Financing" in the consolidated financial
statements  contained  herein for more details on our  acquisition of assets and
debenture and stock financings.

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

ITEM 3:   Quantitative and Qualitative Disclosures About Market Risk

         We had  approximately  $14,407,000  in cash  and cash  equivalents  and
short-term  investments  at March 31, 2005. To the extent that our cash and cash
equivalents  exceed our near term  funding  needs,  we invest the excess cash in
three to six month high  quality  interest  bearing  financial  instruments.  We
employ established conservative policies and procedures to manage any risks with
respect to investment exposure.

         We have not entered  into,  and do not expect to enter into,  financial
instruments for trading or hedging purposes.

Item 4: Controls and Procedures

         Our Chairman of the Board (serving as the principal  executive officer)
and the Chief  Financial  Officer  performed  an  evaluation  of our  disclosure
controls and  procedures,  which have been designed to permit us to  effectively
identify and timely  disclose  important  information.  They  concluded that the
controls  and  procedures  were  effective  as of March 31,  2005 to ensure that
material  information  was  accumulated  and  communicated  to  our  management,
including  our  Chief  Executive  Officer  and  Chief  Financial   Officer,   as
appropriate to allow timely decisions regarding required disclosure.  During the
quarter  ended March 31, 2005,  we have made no change in our internal  controls
over financial reporting that has materially  affected,  or is reasonably likely
to materially affect, our internal controls over financial reporting.


                           Part II - OTHER INFORMATION

Item 1.   Legal Proceedings

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

                        In June 2002, a former ME/CFS clinical trial patient and
her husband filed a claim in the Superior Court of New Jersey, Middlesex County,
against us, one of our clinical trial investigators and others alleging that she
was harmed in the ME/CFS  clinical trial as a result of negligence and breach of
warranties.  On  June  25,  2004  all  claims  against  us were  dismissed  with
prejudice.  The former  ME/CFS  clinical  trial patient and her husband have now
appealed  the  dismissal  of their  claims  to the New  Jersey  Superior  Court,
Apellate Division, where the matter is now pending.

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

         In  June  2004,  One  Penn  Associates,  L.P.  filed  a  claim  in  the
Philadelphia  Municipal  Court  for the  Commonwealth  of  Pennsylvania  seeking
$44,242.68  for alleged  unpaid  rent and charges  related to our offices in One
Penn  Center in  Philadelphia.  We believe  this claim is without  merit and are
defending  same  pursuant  to the  terms  of our  lease as we were  damaged  and
deprived of the use of a portion of the offices due to water from the landlord's
faulty sprinkler system.

         In  December,  2004 we filed a multicount  complaint  in federal  court
(Southern  District  of  Florida)  against a  conspiratorial  group  seeking  to
illegally manipulate our stock for purposes of bringing about a hostile takeover
of Hemispherx.  The lawsuit alleges that the conspiratorial group commenced with
a plan to seize  control  of our  cash  and  proprietary  assets  by an  illegal
campaign to drive down our stock price and  publish  disparaging  reports on our
management and current fiduciaries. The lawsuit seeks monetary damages from each
member of the  conspiratorial  group as well as injunctions  preventing  further
recurrences of their misconduct.  The conspiratorial group includes Bioclones, a
privately held South African  Biopharmaceutical  company that  collaborated with
us, and  Johannesburg  Consolidated  Investments,  a South African  corporation,
Cyril Donninger, R. B. Kebble, H. C. Buitendag, Bart Goemaere, and John Doe(s).

         On January 10, 2005,  we  initiated a multicount  lawsuit in the United
States  District  Court  for  the  Eastern  District  of  Pennsylvania   seeking
injunctive  relief and damages against a conspiratorial  group, many of whom are
foreign  nationals or companies  located outside the United States alleging that
the conspiratorial group has engaged in secret meetings,  market  manipulations,
fraudulent  misrepresentations,  utilization  of foreign  accounts  and  foreign
secrecy laws all in furtherance of an illegal scheme to take over Hemispherx and
enrich  themselves  at the  expense  of  Hemispherx's  public  shareholders.  On
February  18, 2005 we filed an amended  complaint  in the same  lawsuit  joining
Redlabs,   USA,  Inc.  as  a  defendant  with  the  existing  defendants  R.E.D.
Laboratories,  N.V./S.A.,  Bart Goemaere,  Jan Goemaere,  Dr. Kenny De Meirleir,
Kenneth Schepmans, Johan Goossens, Lieven Vansacker and John Does.

ITEM 2:   Unregistered Sales of Equity Securities and Use of Proceeds

         During the quarter  ended March 31, 2005,  we issued 1) an aggregate of
19,737 shares to our Directors as part of their quarterly compensation, 2) 2,195
shares to Business Asia Corporation for services  performed and 3) 46,667 shares
to  Cardinal  Securities  reflecting  50% of fees  earned  on the  August,  2004
financing.

         All  of the  foregoing  transactions  were  conducted  pursuant  to the
exemption  from  registration  provided by Section 4(2) of the Securities Act of
1933.

         We did not repurchase  any of our  securities  during the quarter ended
March 31, 2005.
