                                 PROXY STATEMENT

                           HEMISPHERX BIOPHARMA, INC.
                               1617 JFK Boulevard
                        Philadelphia, Pennsylvania 19103

                                  INTRODUCTION

      This proxy statement is furnished in connection  with the  solicitation of
proxies for use at the annual meeting of stockholders  of Hemispherx  Biopharma,
Inc. ("Hemispherx" or the "Company") to be held on Wednesday, June 22, 2005, and
at any  adjournments.  The  accompanying  proxy  is  solicited  by the  Board of
Directors  of  Hemispherx  and is  revocable  by the  stockholder  by  notifying
Hemispherx's Corporate Secretary at any time before it is voted, or by voting in
person at the annual meeting.  This proxy statement and accompanying  proxy will
be distributed to stockholders beginning on or about May 10, 2005. The principal
executive offices of Hemispherx are located at 1617 JFK Boulevard, Philadelphia,
Pennsylvania 19103, telephone (215) 988-0080.

                      OUTSTANDING SHARES AND VOTING RIGHTS

RECORD DATE; OUTSTANDING SHARES

      Only  stockholders  of record at the close of business on April 25,  2005,
the record  date,  are  entitled  to  receive  notice of, and vote at the annual
meeting.  As of the record date, the number and class of stock  outstanding  and
entitled to vote at the meeting was 50,028,237 shares of common stock, par value
$.001 per  share.  Each  share of common  stock is  entitled  to one vote on all
matters.  No other class of securities  will be entitled to vote at the meeting.
There are no cumulative voting rights.

      The six nominees receiving the highest number of votes cast by the holders
of common  stock  represented  and  voting at the  meeting  will be  elected  as
Hemispherx's   directors  and  constitute  the  entire  Board  of  directors  of
Hemispherx.  The  affirmative  vote  of  at  least  a  majority  of  the  shares
represented and voting at the annual meeting at which a quorum is present (which
shares voting  affirmatively also constitute at least a majority of the required
quorum) is necessary for approval of Proposal No. 2.

REVOCABILITY OF PROXIES

      If you attend the meeting,  you may vote in person,  regardless of whether
you have submitted a proxy.  Any person giving a proxy in the form  accompanying
this proxy  statement has the power to revoke it at any time before it is voted.
It may be revoked by filing,  with the corporate  secretary of Hemispherx at its
principal  offices,  1617 JFK Boulevard,  Suite 660,  Philadelphia,  PA 19103, a
written  notice of revocation or a duly executed  proxy bearing a later date, or
it may be revoked by attending the meeting and voting in person.

VOTING AND SOLICITATION

      Every stockholder of record is entitled,  for each share held, to one vote
on each proposal or item that comes before the meeting.  There are no cumulative


                                        1


voting rights.  By submitting  your proxy,  you authorize  William A. Carter and
Ransom W.  Etheridge  and each of them to represent  you and vote your shares at
the meeting in accordance with your instructions.  Messrs.  Carter and Etheridge
and each of them may also vote your shares to adjourn  the meeting  from time to
time  and  will  be  authorized  to  vote  your  shares  at any  adjournment  or
postponement of the meeting.

      Hemispherx  has borne the cost of preparing,  assembling  and mailing this
proxy solicitation  material. The total cost estimated to be spent and the total
expenditures  to  date  for,  in  furtherance  of,  or in  connection  with  the
solicitation of stockholders is approximately $35,000.  Hemispherx may reimburse
brokerage firms and other persons  representing  beneficial owners of shares for
their expenses in forwarding soliciting materials to beneficial owners.  Proxies
may be solicited by certain of Hemispherx's  directors,  officers and employees,
without additional compensation, personally, by telephone or by facsimile.

      We have  hired  the firm of  MacKenzie  Partners,  Inc.  to  assist in the
solicitation  of  proxies  on behalf of the Board of  Directors.  MacKenzie  has
agreed to perform this  service for a proposed fee of $5,000 plus  out-of-pocket
expenses.

ADJOURNED MEETING

      The chair of the meeting  may  adjourn  the  meeting  from time to time to
reconvene  at the same or some other  time,  date and place.  Notice need not be
given of any such  adjournment  meeting if the time,  date and place thereof are
announced at the meeting at which the  adjournment is taken.  If the time,  date
and place of the adjournment  meeting are not announced at the meeting which the
adjournment  is taken,  then the  Secretary  of the Company  shall give  written
notice of the time, date and place of the adjournment  meeting not less than ten
(10)  days  prior  to  the  date  of  the  adjournment  meeting.  Notice  of the
adjournment  meeting also shall be given if the meeting is adjourned in a single
adjournment to a date more than 30 days or in successive  adjournments to a date
more than 120 days after the original date fixed for the meeting.

TABULATION OF VOTES

      The votes will be tabulated and certified by Hemispherx's transfer agent.

VOTING BY STREET NAME HOLDERS

      If you are the  beneficial  owner of  shares  held in  "street  name" by a
broker,  the broker,  as the record  holder of the  shares,  is required to vote
those  shares  in  accordance  with  your  instructions.  If  you  do  not  give
instructions to the broker, the broker will nevertheless be entitled to vote the
shares with respect to  "discretionary"  items but will not be permitted to vote
the shares with respect to "non-discretionary"  items (in which case, the shares
will be treated as "broker non-votes").

QUORUM; ABSTENTIONS; BROKER NON-VOTES

      The required  quorum for the transaction of business at the annual meeting
is a  majority  of the  shares of common  stock  entitled  to vote at the annual
meeting,  in person or by proxy.  Shares  that are  voted  "FOR,"  "AGAINST"  or
"WITHHELD  FROM" a matter  are  treated  as being  present  at the  meeting  for
purposes of establishing a quorum and are also treated as shares represented and
voting the votes cast at the annual meeting with respect to such matter.


                                        2


      While there is no  definitive  statutory or case law authority in Delaware
as to the proper treatment of abstentions,  Hemispherx believes that abstentions
should be counted for purposes of determining  both: (i) the presence or absence
of a quorum for the transaction of business;  and (ii) the total number of votes
cast with respect to a proposal  (other than the election of directors).  In the
absence of controlling  precedent to the contrary,  Hemispherx  intends to treat
abstentions in this manner.  Accordingly,  abstentions will have the same effect
as a vote against the proposal (other than the election of directors).

      Under current Delaware case law, while broker non-votes (i.e. the votes of
shares held of record by brokers as to which the  underlying  beneficial  owners
have given no voting instructions) should be counted for purposes of determining
the  presence or absence of a quorum for the  transaction  of  business,  broker
non-votes  should not be counted for purposes of determining the number of votes
cast with respect to the  particular  proposal on which the broker has expressly
not voted.  Hemispherx intends to treat broker non-votes in this manner. Thus, a
broker  non-vote  will make a quorum  more  readily  obtainable,  but the broker
non-vote will not otherwise affect the outcome of the voting on a proposal.

DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS

      Proposals of  stockholders  to be  considered  for  inclusion in the Proxy
Statement  and proxy card for the 2006 Annual  Meeting of  Stockholders  must be
received by the Company's  Secretary,  at Hemispherx  Biopharma,  Inc., 1617 JFK
Boulevard, Philadelphia, PA 19103 no later than January 21, 2006.

      Pursuant to the  Company's  Restated  and Amended  Bylaws all  stockholder
proposals  may be brought  before an annual  meeting of  stockholders  only upon
timely notice thereof in writing having been given the Secretary of the Company.
To be timely, a stockholder's  notice, for all stockholder  proposals other than
the nomination of candidates  for director,  shall be delivered to the Secretary
at the principal  executive  offices of the Company not less than sixty (60) nor
more than  ninety  (90) days prior to the  anniversary  date of the  immediately
preceding annual meeting of stockholders;  provided,  however, that in the event
that the annual meeting is called for a date that is not within thirty (30) days
before or after such anniversary date, the  stockholder's  notice in order to be
timely  must be so  received  not later than the close of  business on the tenth
(10th)  day  following  the day on which  such  notice of the date of the annual
meeting was mailed or public  disclosure  of the date of the annual  meeting was
made, whichever first occurs. To be timely, a stockholder's notice, with respect
to a stockholder  proposal for nomination of candidates  for director,  shall be
delivered to the Secretary at the principal executive offices of the Company not
less than ninety (90) nor more than one hundred  twenty  (120) days prior to the
anniversary  date of the immediately  preceding  annual meeting of stockholders;
provided,  however,  that in the event that the  annual  meeting is called for a
date that is not within thirty (30) days before or after such anniversary  date,
the  stockholder's  notice in order to be timely must be so  received  not later
than the close of business on the tenth  (10th) day  following  the day on which
such notice of the date of the annual meeting was mailed or public disclosure of
the date of the annual  meeting  was made,  whichever  first  occurs.  Provided,
however, in the event that the stockholder proposal relates to the nomination of
candidates  for  director and the number of directors to be elected to the Board
of  Directors of the Company at an annual  meeting is increased  and there is no
public  announcement  by the Company  naming all of the nominees for director or
specifying  the size of the  increased  Board of  Directors at least one hundred
days prior to the first  anniversary of the preceding  year's annual meeting,  a
stockholder's  notice shall also be considered  timely, but only with respect to
nominees  for  any new  positions


                                       3


created by such  increase,  if it shall be  delivered  to the  Secretary  at the
principal  executive offices of the Company not later than the close of business
on the tenth day  following the day on which such public  announcement  is first
made  by  the  Company.  All  stockholder  proposals  must  contain  all  of the
information  required under the Company's  Bylaws,  a copy of which is available
upon written request, at no charge, from the Secretary. The Company reserves the
right to  reject,  rule out of order,  or take  other  appropriate  action  with
respect to any  proposal  that does not comply  with these and other  applicable
requirements.

                      INFORMATION CONCERNING BOARD MEETINGS

      The Board of Directors is responsible  for the management and direction of
Hemispherx  and  for   establishing   broad   corporate   policies.   A  primary
responsibility  of  the  Board  is to  provide  effective  governance  over  the
Company's affairs for the benefit of its  stockholders.  In all actions taken by
the Board,  the Directors are expected to exercise  their  business  judgment in
what  they  reasonably  believe  to be the best  interests  of the  Company.  In
discharging that obligation,  Directors may rely on the honesty and integrity of
the Company's senior executives and its outside advisors and auditors.

      The  Board  of  Directors  and  various   committees  of  the  Board  meet
periodically  throughout the year to receive and discuss operating and financial
reports  presented by the chairman of the Board, the chief executive officer and
chief  financial  officer  as well as reports  by  experts  and other  advisors.
Corporate review sessions are also offered to Directors to help familiarize them
with Hemispherx's technology and operations. Members of the Board are encouraged
to  attend   Board   meetings   in  person,   unless  the  meeting  is  held  by
teleconference.  The Board held seven  meetings in 2004.  All committee  members
attended  these  meetings  except for Dr. Kiani who  attended  four of the seven
meetings.  Directors are expected to attend the Annual  Meeting  absent  unusual
circumstances,  although  Hemispherx has no formal policy on the matter.  All of
the Directors except one attended the 2004 Annual Meeting.

      In March 2005, Steven D. Spence was appointed to the Board of Directors of
Hemispherx  Biopharma,  Inc.  to  serve  until  his  successor  is  elected  and
qualified.

      Dr. Esteve resigned from the Board on December 16, 2004, after serving one
year.

      In 2004, the non-employee  members of the Board of Directors met two times
in executive session,  i.e. with no employee  Directors or management  personnel
present. In April 2005, Richard Piani was appointed the Lead Director to preside
over future  meetings.  Interested  persons may contact the Lead Director or the
non-employee  Directors by sending  written  comments  through the Office of the
Secretary of the Company.  The Office will either forward the original materials
as addressed or provide  Directors with summaries of the  submissions,  with the
originals available for review at the Directors' request.

                 INFORMATION CONCERNING COMMITTEES OF THE BOARD

      The Board of Directors maintains the following committees:

Executive Committee.

      The Executive Committee is composed of William A. Carter,  Chief Executive
Officer,  Ransom W.  Etheridge,  Secretary and  director,  and Steven D. Spence,
director. Mr. Spence was appointed to the Committee in April 2005. The Executive
Committee  had one  meeting  in  2004.  All  committee  members  attended  these
meetings.   The  Committee  assists  the  Board  by  making  recommendations  to
management regarding general business matters of Hemispherx.

Compensation Committee.

      The Compensation Committee is composed of Dr. William Mitchell,  director,
Richard C. Piani,  director,  and Dr. Iraj-Eqhbal Kiani, director. Dr. Kiani was

Corporate Governance and Nomination Committee.

      In 2004,  the  Nominating  Committee  had one meeting and all members were
present.

      In April  2005,  in  conjunction  with the  Board  reconfiguration  of the
Nominating  Committee to include  corporate  governance,  the Board of Directors
appointed  Steven  D.  Spence  to the  newly  formed  Corporate  Governance  and
Nomination  Committee.   This  Corporate  Governance  and  Nomination  Committee
consists of Dr.  William  Mitchell,  Committee  Chair,  Richard Piani and Steven
Spence.  All of the members of the  Committee  meet the  independence  standards
contained within the AMEX Company Guide and the Hemispherx  Corporate Governance
Guidelines.  The full text of the Corporate  Governance and Nomination Committee
Charter as well as the  Corporate  Governance  Guidelines,  as  approved  by the
Board, are available on our website: www.hemispherx.net.

      As  discussed   below,  the  Committee  is  responsible  for  recommending
candidates to be nominated by the Board for election by the  stockholders  or to
be appointed by the Board of Directors  to fill  vacancies  consistent  with the
criteria  approved  by the  Board.  It  also  is  responsible  for  periodically
assessing    Hemispherx's    Corporate   Governance    Guidelines   and   making
recommendations  to the  Board  for  amendments,  recommending  to the Board the
compensation  of  Directors,  taking  a  leadership  role in  shaping  corporate
governance, and overseeing an annual evaluation of the Board.

      The Corporate  Governance  and  Nomination  Committee is  responsible  for
identifying  candidates who are eligible under the  qualification  standards set
forth in Hemispherx's Corporate Governance Guidelines to serve as members of the
Board.  It is authorized to retain search firms and other  consultants to assist
it in identifying  candidates and fulfilling its other duties.  The Committee is
not limited to any specific process in identifying  candidates and will consider
candidates  suggested by  stockholders.  Candidates are recommended to the Board
after  consultation  with the  Chairman  of the  Board.  In  recommending  Board
candidates, the Committee considers a candidate's:  (1) general understanding of
elements  relevant  to the  success of a large  publicly  traded  company in the
current business environment,  (2) understanding of Hemispherx's  business,  and
(3)  educational  and   professional   background.   The  Committee  also  gives
consideration to a candidate's judgment,  competence,  anticipated participation
in Board  activities,  experience,  geographic  location and special  talents or
personal  attributes.  Stockholders  who wish to  suggest  qualified  candidates
should write to the Corporate Secretary,  Hemispherx  Biopharma,  Inc., 1617 JKF
Blvd., Ste. 660, Philadelphia, PA 19103, stating in detail the qualifications of
such persons for consideration by the Committee.

      The Company aspires to the highest standards of ethical conduct; reporting
results with accuracy and transparency; and maintaining full compliance with the
laws,  rules and regulations  that govern the Company's  business.  Hemispherx's
Corporate Governance Guidelines embody many of our policies and procedures which
are the  foundation of our  commitment to best  practices.  The  guidelines  are
reviewed  annually,  and  revised as  necessary  to  continue  to  reflect  best
practices.

Audit Committee and Audit Committee Expert.

      Hemispherx's Audit Committee of the Board of Directors consists of Richard
Piani, Committee Chairman,  William Mitchell, M.D. and Steven Spence. Mr. Piani,
Dr. Mitchell,  and Mr. Spence are all determined by the Board of Directors to be
independent  directors as required under Section  121B(2)(a) of


                                       8


the AMEX Company Guide.  Mr. Spence serves as the financial expert as defined in
Securities and Exchange  Commission rules on the committee.  Hemispherx believes
Mr. Piani, Dr. Mitchell, and Mr. Spence to be independent of management and free
of any  relationship  that would  interfere  with their  exercise of independent
judgment as members of this  committee.  The  principal  functions  of the Audit
Committee are to (i) assist the Board in fulfilling its oversight responsibility
relating to the annual independent audit of Hemispherx's  consolidated financial
statements and internal control over financial reporting,  the engagement of the
independent  registered  public  accounting  firm  and  the  evaluation  of  the
independent registered public accounting firm's qualifications, independence and
performance (ii) prepare the reports or statements as may be required by AMEX or
the  securities  laws,  (iii)  assist  the  Board in  fulfilling  its  oversight
responsibility  relating to the integrity of Hemispherx's  financial  statements
and financial  reporting process and Hemispherx's  system of internal accounting
and financial controls,  (iv) discuss the financial  statements and reports with
management,  including any  significant  adjustments,  management  judgments and
estimates,  new accounting policies and disagreements with management,  and (vi)
review  disclosures by independent  accountants  concerning  relationships  with
Hemispherx and the performance of Hemispherx's independent accountants.

      The Audit  Committee  Charter is attached to this proxy statement as Annex
A.

Audit Committee Report.

      The primary  responsibility of the Audit Committee (the "Committee") is to
assist the Board of Directors in discharging its oversight responsibilities with
respect to  financial  matters and  compliance  with laws and  regulations.  The
primary methods used by the Committee to fulfill its responsibility with respect
to financial matters are:

      o     To appoint,  evaluate,  and, as the Committee may deem  appropriate,
            terminate and replace our independent auditors;

      o     To monitor the independence of our independent auditors;

      o     To determine the compensation of our independent auditors;

      o     To  pre-approve  any  audit  services,  and any  non-audit  services
            permitted  under  applicable law, to be performed by our independent
            auditors;

      o     To review our risk exposures,  the adequacy of related  controls and
            policies with respect to risk assessment and risk management;

      o     To monitor the  integrity of our financial  reporting  processes and
            systems of control regarding finance,  accounting,  legal compliance
            and information systems;

      o     To facilitate and maintain an open avenue of communication among the
            Board of Directors, management and our independent auditors.

      The Audit  Committee  is  composed of three  Directors,  and the Board has
determined  that each of those  Directors is independent as that term is defined
in Sections 121(B)(2)(a) of the American Stock Exchange Company Guide.

      In April 2005,  the Board elected Mr.  Spence,  replacing Dr.  Iraj-Eqhbal
Kiani, and re-elected Mr. Piani and Dr. Mitchell to the Audit Committee, subject
to their election to the Board by stockholders at the Annual Meeting.


                                       9


      The Committee met four times in 2004.  All committee  members were present
at the meetings except for Dr.  Iraj-Eqhbal Kiani who was present at only two of
these meetings.

      In  discharging  its  responsibilities   relating  to  internal  controls,
accounting  and  financial  reporting  policies  and  auditing  practices,   the
Committee  discussed with our independent  registered  public  accountants,  BDO
Seidman,  LLP,  the  overall  scope and  process  for its audit.  The  Committee
regularly meets with BDO Seidman,  LLP, with and without management  present, to
discuss  the  results  of its  examinations,  the  evaluations  of our  internal
controls and the overall quality of our financial reporting.

      The Committee has discussed with BDO Seidman,  LLP its judgments about the
quality,  in addition to the  acceptability,  of our  accounting  principles  as
applied in our  financial  reporting,  as  required  by  Statement  on  Auditing
Standards No. 61 "Communications with Audit Committees."

      The Committee also has received the written  disclosures and a letter from
BDO Seidman,  LLP that is required by the Independence  Standards Board Standard
No. 1, Independence  Discussions with Audit  Committees,  and has discussed with
BDO Seidman, LLP their independence.

      The Committee has met and held discussions with management.  The Committee
has reviewed and discussed with  management  Hemispherx's  audited  consolidated
financial  statements as of and for the fiscal year ended  December 31, 2003 and
the  audited  consolidated  financial  statements  as of and for the fiscal year
ended  December 31, 2004 as well as The  internal  control  requirements  of the
Sarbanes-Oxley Act.

      Based on the reviews and  discussions  referred  to above,  the  Committee
recommended  to the Board of  Directors  that the audited  financial  statements
referred to above be included in our Annual  Report for the year ended  December
31, 2004.

      This  report  is  respectfully  submitted  by the  members  of  the  Audit
Committee of the Board of Directors.

                           Richard C. Piani, Chairman
                               William M. Mitchell

Strategic Planning Committee.

      The Strategic Planning Committee is composed of William A. Carter, Richard
C. Piani, and Ransom Etheridge.  Mr. Etheridge was appointed to the Committee in

attendance.  The Strategic Planning Committee makes recommendations to the Board
of Directors of priorities in the application of Hemispherx's  financial  assets
and human resources in the fields of research, marketing and manufacturing.  The
Strategic  Planning  Committee  has engaged a number of leading  consultants  in
healthcare,  drug development and  pharmaeconomics  to assist in the analysis of
various products being developed and/or potential  acquisitions being considered

In April 2005, the Company designated Richard Piani as lead director.  Mr. Piani

Code of Ethics and Business Conduct

Hemispherx's  Board of Directors  adopted a code of ethics and business  conduct
for officers,  directors  and  employees  that went into effect on May 19, 2003.
This  code has  been  presented  and  reviewed  by each  officer,  director  and
employee.  You may  obtain  a copy of this  code  by  visiting  our web  site at
www.hemispherx.net or by written request to our Office Administrator at 1617 JFK

to approve any waivers of the code of ethics and business  conduct for Directors
or  executive  officers  and we are  required to  disclose  any such waiver in a
Current Report on Form 8-K within four business days.

Stock Ownership Guidelines

      In April 2005,  the Board of  Directors  adopted a set of stock  ownership
guidelines  for Directors and officers.  The Board  believes that  Directors and
officers more effectively represent the interest of Hemispherx's shareholders if
they are  shareholders  themselves.  At this  time,  most of our  Directors  and
officers  are  shareholders  and this  guideline  was adopted to assure that the
present  Directors  and  officers  continue  to  participate  as well as  future
Directors  and officers.  The full text of the Stock  Ownership  Guidelines,  as
approved by the Board, are available on our website: www.hemispherx.net.

Employment and Change in Control Agreements

      On March 11, 2005, our Board of Directors,  at the  recommendation  of the
Compensation  Committee,  approved an amended and restated employment  agreement
and an amended and restated engagement agreement with Dr. William A. Carter.

      The amended and restated  employment  agreement  provides for Dr. Carter's
employment as our Chief  Executive  Officer and Chief  Scientific  Officer until
December  31,  2010  unless  sooner  terminated  for  cause or  disability.  The
agreement automatically renews for successive one year periods after the initial
termination  date unless we or Dr. Carter give written notice otherwise at least
ninety days prior to the termination date or any renewal period.  Dr. Carter has
the right to terminate  the  agreement  on 30 days' prior  written  notice.  The
initial  base  salary  retroactive  to January 1, 2005 is  $290,888,  subject to
adjustment based on the average increase or decrease in the Consumer Price Index
for the prior year. In addition,  Dr. Carter could receive an annual performance
bonus  of up to  25%  of  his  base  salary,  at  the  sole  discretion  of  the
Compensation  Committee of the Board of Directors,  based on his  performance or
our  operating  results.  Dr.  Carter will not  participate  in any  discussions
concerning the determination of his annual bonus. Dr. Carter is also entitled to
an incentive  bonus of 0.5% of the gross proceeds  received by us from any joint
venture  or  corporate  partnering  arrangement.  Dr.  Carter's  agreement  also
provides that he be paid a base salary and benefits  through the last day of the
then term of the agreement if he is terminated without "cause",  as that term is
defined in agreement. In addition,  should Dr. Carter terminate the agreement or
the  agreement  be  terminated  due to his death or  disability,  the  agreement
provides that Dr Carter be paid a base salary and benefits  through the last day
of the month in which the  termination  occurred  and for an  additional  twelve
month period. Pursuant to his original agreement, Dr. Carter was granted options
to purchase  73,728 (post split)  shares in 1991.  The exercise  period of these
options  is  extended  through  December  31,  2010  and,  should  Dr.  Carter's
employment agreement be extended beyond that date, the option exercise period is
further extended to the last day of the extended


                                       17


employment period.

      On May 9,  2005,  our Board of  Directors,  at the  recommendation  of the
Compensation  Committee,  approved an  amendment  to the  amended  and  restated
employment  agreement  with Dr.  William A.  Carter  whereby  the amount of life
insurance  provided for the benefit of Dr.  Carter on his life was  increased to
$2,800,000.

      The amended and restated engagement  agreement,  retroactive to January 1,
2005,  provides for our  engagement  of Dr.  Carter as a  consultant  related to
patent  development,  as one of our  Directors  and as chairman of the Executive
Committee  of our Board of  Directors  until  December  31, 2010  unless  sooner
terminated  for cause or  disability.  The  agreement  automatically  renews for
successive  one year periods after the initial  termination  date or any renewal
period.  Dr.  Carter has the right to terminate  the agreement on 30 days' prior
written notice. The initial base fee as of January 1, 2004 is $207,777,  subject
to annual  adjustments  equal to the  percentage  increase or decrease of annual
dollar value of Directors' fees provided to our Directors during the prior year.
The annual fee is further subject to adjustment based on the average increase or
decrease in the Consumer Price Index for the prior year. In addition, Dr. Carter
could receive an annual  performance  bonus of up to 25% of his base fee, at the
sole direction of the Compensation Committee of the Board of Directors, based on
his performance.  Dr. Carter will not participate in any discussions  concerning
the  determination  of this annual bonus.  Dr. Carter's  agreement also provides
that he be paid  his  base fee  through  the  last  day of the then  term of the
agreement if he is terminated  without  "cause",  as that term is defined in the
agreement.  In  addition,  should Dr.  Carter  terminate  the  agreement  or the
agreement be terminated due to his death or disability,  the agreement  provides
that Dr.  Carter be paid fees due him through the last day of the month in which
the termination occurred and for an additional twelve month period.

      On February 14, 2005 we entered  into an agreement  with The Sage Group of
Branchburg,  New Jersey for R. Douglas Hulse, an Executive  Director of The Sage
Group,  to serve as President  and Chief  Operating  Officer of our company.  In
addition,  other  Sage  Group  principals  and  Senior  Directors  will  be made
available  to assist as needed.  The  engagement  is expected to continue  for a
period of 18 months;  however,  it is  terminable  on 30 days written  notice by
either party after 12 months.  Compensation  for the services include a ten year
warrant to purchase  250,000  shares of our common stock at an exercise price of
$1.55. These warrants are to be issued to Sage Healthcare Advisors,  LLC and are
to vest at the rate of 12,500 per month of the  engagement  with 25,000  vesting
upon completion of the eighteenth month.  Vesting  accelerates in the event of a
merger or a purchase of a majority of our assets or equity.  The Sage Group also
is to receive a monthly retainer of $10,000 for the period of the engagement. In
addition, for each calendar year (or part thereof) during which the agreement is
in effect,  The Sage Group will be entitled to an  incentive  bonus in an amount
equal to 0.5% of the gross  proceeds  received  by us during  such year from any
joint ventures or corporate  partnering  arrangements.  After termination of the
agreement,  The Sage Group will only be entitled to receive the incentive  bonus
based upon gross proceeds  received by us during the two year period  commencing
on the  termination  of the  agreement  with  respect to any joint  ventures  or
corporate  partnering  arrangements  entered  into by us during  the term of the
agreement.  Mr. Hulse will devote approximately two to two and one half days per
week to our business.

      We entered into an engagement  agreement,  retroactive to January 1, 2005,
with Ransom W. Etheridge  which provides for Mr.  Etheridge's  engagement as our
General  Counsel until  December 31, 2009 unless sooner  terminated for cause or
disability.  The agreement  automatically renews for successive one year periods
after the initial  termination  date  unless we or Mr.  Etheridge  give  written
notice  otherwise  at least  ninety  days prior to the  termination  date or any
renewal  period.  Mr.  Etheridge  has the right to terminate the agreement on 30
days' prior written  notice.  The initial annual fee for services is $96,000 and


                                       18


is annually  subject to adjustment  based on the average increase or decrease in
the Consumer  Price Index for the prior year.  Mr.  Etheridge's  agreement  also
provides  that he be paid all fees  through the last day of then current term of
the agreement if he is terminated without "cause" as that term is defined in the
agreement.  In addition,  should Mr.  Etheridge  terminate  the agreement or the
agreement be terminated due to his death or disability,  the agreement  provides
that Mr. Etheridge be paid the fees due him through the last day of the month in
which the termination  occurred and for an additional  twelve month period.  Mr.
Etheridge will devote approximately 85% of his business time to our business.

      We entered into an amended and restated engagement agreement,  retroactive
to January 1, 2005,  with Robert E. Peterson which  provides for Mr.  Peterson's
engagement as our Chief Financial  Officer until December 31, 2010 unless sooner
terminated for cause or disability.  Mr. Peterson has the right to terminate the
agreement on 30 days' prior written notice.  The initial annual fee for services
is $202,680 and is annually  subject to increases based on the average  increase
in the cost of inflation index for the prior year. Mr. Peterson shall receive an
annual bonus in each year that our Chief  Executive  Officer is granted a bonus.
The bonus shall equal a percentage of Mr.  Peterson's  base annual  compensation
comparable to the percentage bonus received by the Chief Executive  Officer.  In
addition,  Mr.  Peterson  shall  receive  bonus  compensation  upon Federal Drug
Administration  approval of commercial  application of Ampligen.  Mr. Peterson's
agreement  also  provides  that he be paid all fees through the last day of then
current term of the agreement if he is terminated  without  "cause" as that term
is defined in the  agreement.  In addition,  should Mr.  Peterson  terminate the
agreement or the agreement be  terminated  due to his death or  disability,  the
agreement  provides that Mr.  Peterson be paid the fees due him through the last
day of the month in which the termination  occurred and for an additional twelve
month period. Mr. Peterson will devote approximately 85% of his business time to
our business.

      On March 11, 2005 the Board of Directors, deeming it essential to the best
interests  of our  shareholders  to  foster  the  continuous  engagement  of key
management  personnel  and  recognizing  that, as is the case with many publicly
held  corporations,  a change of control might occur and that such  possibility,
and the uncertainty and questions which it might raise among  management,  might
result in the departure or distraction of management  personnel to the detriment
of our company and our  shareholders,  determined to reinforce and encourage the
continued  attention  and  dedication  of  members  of our  management  to their
engagement   without   distraction  in  the  face  of   potentially   disturbing
circumstances arising from the possibility of a change in control of our company
and entered into identical  agreements  regarding change in control with William
A. Carter, our Chief Executive Officer and Chief Scientific  Officer,  Robert E.
Peterson,  our Chief  Financial  Officer  and Ransom W.  Etheridge,  our General
Counsel.  Each of the agreements  regarding  change in control became  effective
March  11,  2005  and  continue  through  December  31,  2007 and  shall  extend
automatically  to the third  anniversary  thereof  unless we give  notice to the
other party prior to the date of such extension that the agreement term will not
be extended. Notwithstanding the foregoing, if a change in control occurs during
the term of the agreements, the term of the agreements will continue through the
second anniversary of the date on which the change in control occurred.  Each of
the  agreements  entitles  William A. Carter,  Robert E.  Peterson and Ransom W.
Etheridge,  respectively,  to change of  control  benefits,  as  defined  in the
agreements  and  summarized   below,   upon  their  respective   termination  of
employment/engagement  with our company during a potential change in control, as
defined  in the  agreements  or after a change in  control,  as  defined  in the
agreements,  when  their  respective  terminations  are caused (1) by us for any
reason other than permanent disability or cause, as defined in the agreement (2)
by  William  A.  Carter,   Robert  E.  Peterson   and/or  Ransom  W.  Etheridge,
respectively,  for good reason as defined in the agreement or, (3) by William A.
Carter,  Robert E. Peterson  and/or Ransom W.  Etheridge,  respectively  for any
reason during the 30 day period commencing on the first date which is six months
after the date of the change in control.


                                       19


The benefits for each of the foregoing executives would be as follows:

      o     A lump sum cash  payment of three  times his base  salary and annual
            bonus amounts; and

      o     Outplacement benefits.

Each  agreement  also  provides  that the  executive is entitled to a "gross-up"
payment  to make him whole  for any  federal  excise  tax  imposed  on change of
control or severance payments received by him.

Dr. Carter's agreement also provides for the following benefits:

      o     Continued  insurance  coverage through the third  anniversary of his
            termination; and

      o     Retirement  benefits computed as if he had continued to work for the
            above period.

Compensation of Directors

      The compensation package for Members of the Board of Directors was changed
on September 9, 2003. Board member  compensation  consists of an annual retainer
of $100,000 to be paid 50% in cash and 50% in Company common stock. On September
9, 2003 the Directors  approved a 10 year plan which  authorizes up to 1,000,000
shares  for  use  in  supporting  this  compensation  plan.  In  addition,   all
non-employee  Directors  received some  compensation in 2003 for special project
work performed on our behalf. This project work ceased as of September 30, 2003.
All Directors have been granted options to purchase common stock under our Stock
Option  Plans  and/or  Warrants  to  purchase  common  stock.  We  believe  such
compensation  and payments  are  necessary in order for us to attract and retain
qualified outside Directors.

2004 Equity Incentive Plan

      Our 2004 Equity  Incentive  Plan ("2004  Plan")  provides for the grant of
non-qualified and incentive stock options, stock appreciation rights, restricted
stock and other stock awards to our employees,  Directors, officers, consultants
and advisors  for the  purchase of up to an  aggregate  of  8,000,000  shares of
common stock. The 2004 plan is administered by the Board of Directors, which has
complete  discretion to select eligible  individuals to receive and to establish
the terms of grants  under the plan.  Stock  options  awarded  under the  Equity
Incentive  Plan may be  exercisable at such times (not later than 10 years after
the date of grant) and at such exercise  prices (not less than fair market value
at the date of  grant) as the Board may  determine.  The Board may  provide  for
options to become immediately  exercisable upon a "change in control" as defined
in the plan. The number of shares of common stock  available for grant under the
2004 Plan is subject to adjustment for changes in capitalization. As of December
31, 2004, 7,366,920 shares were available for grants under the 2004 Plan. Unless
sooner  terminated,  the Equity  Incentive  Plan will  continue  in effect for a
period of 10 years from its effective date

1990 Stock Option Plan

      Our 1990 Stock Option Plan,  as amended  ("1990  Plan"),  provides for the
grant of options to our employees, Directors, officers, consultants and advisors
for the purchase of up to an aggregate of 460,798  shares of common  stock.  The
1990  plan  is  administered  by the  Compensation  Committee  of the  Board  of
Directors,  which has complete  discretion  to select  eligible  individuals  to
receive and to  establish  the terms of option  grants.  The number of shares of
common stock  available  for grant under the 1990 Plan is subject to  adjustment


                                       20


for  changes in  capitalization.  As of  December  31,  2004,  no  options  were
available  for grants  under the 1990 plan.  This plan  remains in effect  until
terminated by the Board of Directors or until all options are issued.

401(K) Plan

      In December 1995, we established a defined  contribution  plan,  effective
January 1, 1995,  entitled the Hemispherx  Biopharma  employees  401(K) Plan and
Trust  Agreement.  All of our full time employees are eligible to participate in
the 401(K) plan following one year of employment. Subject to certain limitations
imposed by federal tax laws,  participants  are eligible to contribute up to 15%
of their salary (including bonuses and/or commissions) per annum.  Participants'
contributions  to  the  401(K)  plan  may be  matched  by  Hemispherx  at a rate
determined  annually by the Board of  Directors.  Each  participant  immediately
vests in his or her deferred salary contributions,  while our contributions will
vest over one year. In 2004 we provided matching  contributions to each employee
for up to 6% of annual pay for a total of $76,886 for all eligible employees.

Compensation Committee Interlocks and Insider Participation

      During the  fiscal  year  ended  December  31,  2004,  the  members of our
Compensation  Committee  were  William  Mitchell and Richard  Piani.  Please see
"Certain   Relationships   And  Related   Transactions"   above  for  additional
information.

      Notwithstanding  anything to the  contrary,  the  following  report of the
Compensation  Committee,  the report of the Audit  Committee  on page 9, and the
performance graph on page 25 shall not be deemed  incorporated by reference this
Proxy  Statement  into any filing under the Securities Act of 1933, or under the
Securities  Exchange  Act  of  1934,  except  to the  extent  that  the  Company
specifically incorporates this information by reference, and shall not otherwise
be deemed filed under such Acts.

Compensation Committee Report on Compensation

      The Compensation  Committee makes recommendations  concerning salaries and
compensation for our employees and consultants.

      The following report of the compensation committee discusses our executive
compensation  policies and the basis of the  compensation  paid to our executive
officers in 2004.

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

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

Base Salary

      The Summary  Compensation  Table shows  amounts  earned during 2004 by our
executive  officers.  The base compensation of such executive officers is set by
terms of the employment agreement entered into with each such executive officer.
We established  the base salaries for Chief  Executive  Officer,  Dr. William A.
Carter  under an  employment  agreement  in  December  3, 1998 (as  amended  and
restated on March 11, 2005), which provides for a base salary of


                                       21


$290,887.68.  In addition,  we entered into an agreement with Dr. Carter for his
services as a consultant related to patient development,  development of patents
and as a member of our Board of  Directors.  This  agreement  establishes a base
annual fee of $207,776.88.  Both agreements are subject to annual cost of living
adjustments.  Dr. Carter is entitled to an annual performance bonus of up to 25%
of the base  salary of each  agreement  at the  discretion  of the  compensation
committee of the Board of Directors.

      On March 11, 2005, we entered into an extended  engagement  agreement with
Robert E. Peterson, Chief Financial Officer retroactive to January 1, 2005 for a
base annual fee of $202,680 until December 31, 2010.  Mr.  Peterson's  agreement
allows for annual cost of living increases and a performance bonus.

      On March 11, 2005, we entered into an engagement  agreement with Ransom W.
Etheridge,  Corporate  General  Counsel,  retroactive  to January 1, 2005 for an
annual fee of $96,000 until December 31, 2009.

Annual Incentive

      Our Chief Executive  Officer and our Chief Financial  Officer are entitled
to an annual incentive bonus as determined by the  compensation  committee based
on such executive  officers'  performance during the previous calendar year. The
cash  bonus  awarded to our Chief  Executive  Officer in 2004 and the cash bonus
awarded to the Chief  Financial  Officer in 2004 were  determined  based on this
provision in their employment agreements.

Long-Term Incentives

      We grant long-term  incentive  awards  periodically to align a significant
portion of the executive compensation program with stockholder interest over the
long-term  through  encouraging  and  facilitating  executive  stock  ownership.
Executives are eligible to participate in our incentive stock option plans.  Our
Chief Executive Officer and President,  Dr. William Carter,  received a grant of
320,000 stock options in 2004.  These options are exercisable at $2.60 per share
and expire on September 7, 2014, unless previously exercised. The options vested
on September 8, 2004.

      On June 23, 2004, our Chief  Financial  Officer,  Robert E. Peterson,  was
granted 50,000 stock options exercisable at $3.44 per share expiring on June 22,
2014 unless previously  exercised.  These options were issued in connection with
his renewed and extended employment agreement. On September 8, 2004 Mr. Peterson
was granted  13,824 stock  options  exercisable  at $2.60 per share  expiring on
September 7, 2014.

      Ransom Etheridge, our Corporate Secretary and General Counsel, was awarded
50,000  stock  options  on  September  8,  2004  exercisable  at $2.60 per share
expiring September 7, 2014, unless previously exercised.

Chief Executive Officer Compensation

      The  Summary  Compensation  Table  shows  that  during  the year  2004 the
Company's Chief  Executive  Officer,  Dr. William A. Carter,  earned $605,175 in
base compensation pursuant to the terms of his employment agreements.

      The Compensation  Committee  believes that Dr. Carter's total compensation
is consistent with the median  compensation  for CEO's in comparable  companies.
Factors reviewed by the Compensation Committee's assessment of the Company's and
the CEO's performance  includes  individual  performance,  growth in revenue and
expense management and implementation of the Company's business strategy.

Compliance With Internal Revenue Code Section 162(m).

      One of the factors the Compensation Committee considers in connection with


                                       22


compensation  matters is the  anticipated tax treatment to Hemispherx and to the
executives of the compensation arrangements.  The deductibility of certain types
of  compensation  depends  upon the  timing  of an  executive's  vesting  in, or
exercise of, previously granted rights. Moreover, interpretation of, and changes
in, the tax laws and other factors beyond the Compensation  Committee's  control
also affect the  deductibility  of compensation.  Accordingly,  the Compensation
Committee will not necessarily  limit executive  compensation to that deductible
under  Section  162(m) of the Code.  The  Compensation  Committee  will consider
various  alternatives to preserving the  deductibility of compensation  payments
and benefits to the extent consistent with its other compensation objectives.

           This report submitted by the Compensation Committee of the
                         Company's Board of Directors.

Audit Fees

      Represents fees for  professional  services  provided for the audit of our
annual financial  statements and review of our financial  statements included in
our quarterly  reports and services in connection  with statutory and regulatory
filings.

Audit-Related Fees

      Represents the fees for assurance and related services that are reasonably
related to the  performance of the audit or review of our financial  statements,
including those in 2003 and 2004 related to the acquisition of ISI.

      The Audit  Committee has determined  that BDO Seidman,  LLP's rendering of
these non-audit services is compatible with maintaining  auditors  independence.
The Board of Directors considers BDO Seidman,  LLP to be well qualified to serve
as our independent public  accountants.  The committee also approved the charges
for services performed in 2004.

      The Audit  Committee  pre-approves  all  auditing  services  and the terms
thereof  (which  may  include  providing  comfort  letters  in  connection  with
securities  underwriting) and non-audit  services (other than non-audit services
prohibited  under Section 10A(g) of the Exchange Act or the applicable  rules of
the SEC or the Public Company  Accounting  Oversight Board) to be provided to us
by the independent auditor;  provided,  however, the pre-approval requirement is
waived with respect to the  provisions  of non-audit  services for us if the "de
minimus"  provisions of Section 10A (i)(1)(B) of the Exchange Act are satisfied.
This authority to pre-approve non-audit services may be delegated to one or more
members of the Audit  Committee,  who shall present all decisions to pre-approve
an activity to the full Audit  Committee  at its first  meeting  following  such
decision.


                                       29


      The affirmative vote of at least a majority of the shares  represented and
voting at the Annual  Meeting at which a quorum is present  (which shares voting
affirmatively  also  constitute  at least a majority of the required  quorum) is
necessary for approval of Proposal No. 2.

THE BOARD OF  DIRECTORS  DEEMS  PROPOSAL  NO. 2 TO BE IN THE BEST  INTERESTS  OF
HEMISPHERX AND ITS STOCKHOLDERS AND RECOMMENDS A VOTE "FOR" APPROVAL THEREOF.

                                     GENERAL

      Unless  contrary  instructions  are indicated on the proxy,  all shares of
      common  stock  represented  by valid  proxies  received  pursuant  to this
      solicitation (and not revoked before they are voted) will be voted FOR the
      election of all Directors nominated and FOR Proposal No. 2.

      The Board of  Directors  knows of no  business  other  than that set forth
      above to be  transacted at the meeting,  but if other matters  requiring a
      vote of the  stockholders  arise,  the persons  designated as proxies will
      vote the shares of common stock  represented  by the proxies in accordance
      with  their  judgment  on  such  matters.  If a  stockholder  specifies  a
      different  choice on the proxy,  his or her shares of common stock will be
      voted in accordance with the specification so made.

      IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY. WE URGE YOU TO FILL IN,
      SIGN AND RETURN THE  ACCOMPANYING  FORM OF PROXY IN THE  PREPAID  ENVELOPE
      PROVIDED, NO MATTER HOW LARGE OR SMALL YOUR HOLDINGS MAY BE.

                                             By Order of the Board of Directors,

                                as of April 2005

I. General Statement of Purpose

The  purposes  of the Audit  Committee  of the Board of  Directors  (the  "Audit
Committee") of Hemispherx Biopharma, Inc. (the "Company") are to:

      o     oversee the  accounting  and  financial  reporting  processes of the
            Company and the audits of the Company's financial statements;

      o     take,  or recommend  that the Board of Directors of the Company (the
            "Board")  take,  appropriate  action to oversee the  qualifications,
            independence and performance of the Company's independent registered
            public accountants; and

      o     prepare  the  report  required  by the rules of the  Securities  and
            Exchange  Commission  (the "SEC") to be  included  in the  Company's
            annual proxy statement.

II. Composition

The Audit  Committee  shall  consist of at least three (3) members of the Board,
each of whom must (1) be  "independent"  as defined in  Sections  121 and 803(a)
under the Company Guide of the American  Stock Exchange  ("AMEX");  (2) meet the

the  significant  time and effort  expended by such member to fulfill his or her
duties as an Audit Committee member.

IV. Meetings

out its  responsibilities  under  this  charter,  but not less  frequently  than

quorum for  purposes of holding a meeting and the Audit  Committee  may act by a
vote of a majority of the members present at such meeting. In lieu of a meeting,
the Audit Committee may act by unanimous  written  consent.  The Chairman of the
Audit Committee, in consultation with the other committee members, may determine
the frequency and length of the committee  meetings and may set meeting  agendas
consistent with this Charter.

            o     At least annually,  the Audit Committee shall evaluate its own
                  performance  and report the results of such  evaluation to the

      C.    Matters  Relating to  Selection,  Performance  and  Independence  of
            Independent Auditor

            o     The Audit  Committee  shall be  directly  responsible  for the
                  appointment,  retention and  termination,  and for determining
                  the compensation, of the Company's independent auditor engaged
                  for the  purpose of  preparing  or issuing an audit  report or
                  performing  other  audit,  review or attest  services  for the
                  Company.  The Audit  Committee may consult with  management in
                  fulfilling   these   duties,   but  may  not  delegate   these
                  responsibilities to management.

            o     The  Audit  Committee   shall  be  directly   responsible  for


                                       32


                  oversight of the work of the  independent  auditor  (including
                  resolution  of  disagreements   between   management  and  the
                  independent auditor regarding financial reporting) engaged for
                  the  purpose  of  preparing  or  issuing  an audit  report  or
                  performing  other  audit,  review or attest  services  for the
                  Company.

            o     The Audit  Committee  shall instruct the  independent  auditor
                  that the  independent  auditor  shall  report  directly to the
                  Audit Committee.

            o     The Audit  Committee shall  pre-approve all auditing  services
                  and the terms  thereof  (which may include  providing  comfort
                  letters  in  connection  with  securities  underwritings)  and
                  non-audit services (other than non-audit  services  prohibited
                  under  Section  10A(g) of the Exchange  Act or the  applicable
                  rules of the SEC or the Public  Company  Accounting  Oversight
                  Board)  to be  provided  to the  Company  by  the  independent
                  auditor;  provided,  however, the pre-approval  requirement is
                  waived with respect to the provision of non-audit services for
                  the  Company  if  the  "de  minimus"   provisions  of  Section
                  10A(i)(1)(B) of the Exchange Act are satisfied. This authority
                  to pre-approve  non-audit  services may be delegated to one or
                  more  members of the Audit  Committee,  who shall  present all
                  decisions  to  pre-approve  an  activity  to  the  full  Audit
                  Committee at its first meeting following such decision.

            o     The Audit  Committee  may  review  and  approve  the scope and
                  staffing of the independent auditors' annual audit plan(s).

            o     The Audit Committee shall request that the independent auditor
                  provide the Audit  Committee with the written  disclosures and
                  the letter required by  Independence  Standards Board Standard
                  No.  1,  as  modified  or   supplemented,   require  that  the
                  independent  auditor  submit  to  the  Audit  Committee  on  a
                  periodic  basis a formal  written  statement  delineating  all
                  relationships between the independent auditor and the Company,
                  discuss   with   the   independent   auditor   any   disclosed
                  relationships  or services that may impact the objectivity and
                  independence  of the  independent  auditor,  and based on such
                  disclosures,  statement and discussion  take or recommend that
                  the  Board  take   appropriate   action  in  response  to  the
                  independent   auditor's   report  to  satisfy  itself  of  the
                  independent auditors' independence.

            o     The Audit Committee may consider  whether the provision of the
                  services  covered in Items  9(e)(2) and 9(e)(3) of  Regulation
                  14A of the  Exchange  Act  (or  any  successor  provision)  is
                  compatible  with   maintaining   the   independent   auditor's
                  independence.


                                       33


            o     The Audit Committee  shall evaluate the independent  auditors'
                  qualifications,   performance  and  independence,   and  shall
                  present  its  conclusions  with  respect  to  the  independent
                  auditors to the full  Board.  As part of such  evaluation,  at
                  least annually, the Audit Committee shall:

                  o     obtain  and   review  a  report  or  reports   from  the
                        independent   auditor   describing   (1)  the  auditor's
                        internal  quality-control  procedures,  (2) any material
                        issues    raised   by   the   most    recent    internal
                        quality-control review or peer review of the auditors or
                        by  any  inquiry  or   investigation  by  government  or
                        professional  authorities,  within  the  preceding  five
                        years,  regarding one or more independent audits carried
                        out by the auditors,  and any steps taken to address any
                        such  issues,  and (3) in order to assess the  auditors'
                        independence,  all relationships between the independent
                        auditor and the Company;

                  o     review and evaluate the  performance of the  independent
                        auditor and the lead  partner  (and the Audit  Committee
                        may review and evaluate the performance of other members
                        of the independent auditors' audit staff); and

                  o     assure  the  regular  rotation  of  the  audit  partners
                        (including,  without limitation, the lead and concurring
                        partners)  as  required   under  the  Exchange  Act  and
                        Regulation S-X.

            o     In this regard,  the Audit  Committee  shall also (1) seek the
                  opinion  of  management  and  the  internal  auditors  of  the
                  independent auditors' performance and (2) consider whether, in
                  order to assure continuing auditor independence,  there should
                  be regular rotation of the audit firm.

            o     The Audit  Committee may recommend to the Board  policies with
                  respect to the potential hiring of current or former employees
                  of the independent auditor.

      D.    Audited Financial Statements and Annual Audit

            o     The Audit  Committee shall review the overall audit plan (both
                  internal and external)  with the  independent  auditor and the
                  members of management  who are  responsible  for preparing the
                  Company's financial statements,  including the Company's Chief
                  Financial  Officer  and/or  principal  accounting  officer  or
                  principal  financial  officer (the Chief Financial Officer and
                  such  other   officer  or  officers  are  referred  to  herein
                  collectively as the "Senior Accounting Executive").

            o     The Audit  Committee  shall review and discuss with management
                  (including the Company's Senior Accounting Executive) and with
                  the independent auditor the Company's annual audited financial
                  statements, including (a) all critical accounting policies and
                  practices used or to be used by the Company,


                                       34


                  (b) the Company's  disclosures under "Management's  Discussion
                  and   Analysis  of   Financial   Conditions   and  Results  of
                  Operations" prior to the filing of the Company's Annual Report
                  on Form  10-K,  and (c) and  significant  financial  reporting
                  issues that have arisen in connection  with the preparation of
                  such audited financial statements.

            o     The Audit Committee must review:

                  i.    Any   analyses   prepared  by   management   and/or  the
                        independent auditors setting forth significant financial
                        reporting  issues and judgments made in connection  with
                        the  preparation  of  financial  statements,   including
                        analyses of the effects of  alternative  GAAP methods on
                        the  financial  statements.   The  Audit  Committee  may
                        consider   the   ramifications   of  the   use  of  such
                        alternative  disclosures and treatments on the financial
                        statements,   and  the   treatment   preferred   by  the
                        independent   auditor.  The  Audit  Committee  may  also
                        consider other material written  communications  between
                        the registered  public  accounting  firm and management,
                        such as any management  letter or schedule of unadjusted
                        differences;

                  ii.   Major  issues  as  to  the  adequacy  of  the  Company's
                        internal controls and any special audit steps adopted in
                        light of material control deficiencies;

                  iii.  Major  issues   regarding   accounting   principles  and
                        procedures   and  financial   statement   presentations,
                        including  any  significant  changes  in  the  Company's
                        selection or application of accounting principles; and

                  iv.   The effects of regulatory and accounting initiatives, as
                        well as off-balance  sheet  transactions and structures,
                        on the financial statements of the Company.

            o     The  Audit   Committee  shall  review  and  discuss  with  the
                  independent  auditor  (outside of the presence of  management)
                  how   the   independent    auditor   plans   to   handle   its
                  responsibilities   under  the  Private  Securities  Litigation
                  Reform Act of 1995,  and  request  assurance  from the auditor
                  that Section 10A of the Private  Securities  Litigation Reform
                  Act of 1995 has not been implicated.

            o     The  Audit   Committee  shall  review  and  discuss  with  the
                  independent  auditor any audit  problems or  difficulties  and
                  management's  response thereto.  This review shall include (1)
                  any  difficulties  encountered by the auditor in the course of
                  performing its audit work,  including any  restrictions on the
                  scope of its activities or its access to  information  and (2)
                  any significant disagreements with management.

            o     This review may also include:

                  i.    Any accounting  adjustments  that were noted or proposed
                        by 


                                       35


                        the  auditors  but  were  "passed"  (as   immaterial  or
                        otherwise);

                  ii.   Any communications  between the audit team and the audit
                        firm's national office regarding  auditing or accounting
                        issues presented by the engagement; and

                  iii.  Any management or internal  control  letter  issued,  or
                        proposed to be issues, by the auditors.

            o     The  Audit   Committee  shall  discuss  with  the  independent
                  auditors  those matters  brought to the attention of the Audit
                  Committee  by the  auditors  pursuant to Statement on Auditing
                  Standards No. 61, as amended ("SAS 61").

            o     The Audit  Committee  shall also review and  discuss  with the
                  independent  auditors  the report  required to be delivered by
                  such auditors pursuant to Section 10A(k) of the Exchange Act.

            o     If brought to the attention of the Audit Committee,  the Audit
                  Committee  shall  discuss  with the CEO and CFO of the Company
                  (1) all significant  deficiencies  and material  weaknesses in
                  the design or  operation of internal  control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  Company's  ability to record,  process,  summarize  and report
                  financial  information required to be disclosed by the Company
                  in the  reports  that it files or submits  under the  Exchange
                  Act, within the time periods  specified in the SEC's rules and
                  forms,  and  (2)  any  fraud  involving  management  or  other
                  employees  who  have  a  significant  role  in  the  Company's
                  internal control over financial reporting.

            o     Based on the Audit Committee's review and discussions (1) with
                  management of the audited financial  statements,  (2) with the
                  independent auditor of the matters required to be discussed by
                  SAS 61, and (3) with the  independent  auditor  concerning the
                  independent auditor's independence,  the Audit Committee shall
                  make a recommendation to the Board as to whether the Company's
                  audited  financial   statements  should  be  included  in  the
                  Company's Annual Report on Form 10-K for the last fiscal year.

            o     The Audit Committee  shall prepare the Audit Committee  report
                  required by Item 306 of Regulation S-K of the Exchange Act (or
                  any  successor  provision)  to be  included  in the  Company's
                  annual proxy statement.

      E.    Unaudited Quarterly Financial Statements

            o     The  Audit   Committee  shall  review  and  may  discuss  with

                  (1)  the  Company's  quarterly  financial  statements  and the
                  Company's related disclosures under  "Management's  Discussion
                  and   Analysis   of   Financial   Condition   and  Results  of
                  Operations,"  (2) such  issues as may be  brought to the Audit


                                       36

                  Statement  on  Auditing   Standards   No.  100,  and  (3)  any
                  significant  financial  reporting  issues  that have arisen in
                  connection with the preparation of such financial statements.

      F.    Earnings Press Releases

            o     The Audit  Committee  shall  review and discuss the  Company's
                  earnings  and  related  financial  information  expected to be
                  announced  in  any  press  releases,   as  well  as  financial

                  rating   agencies,   including   in  general,   the  types  of
                  information to be disclosed and the types of  presentation  to
                  be made (paying particular attention to the use of "pro forma"

                  receipt, retention and treatment of complaints received by the

                  submission  by employees of the Company of concerns  regarding

            o     The Audit  Committee  may review and  reassess the adequacy of

      A.    Engagement of Advisors

      o     The Audit  Committee may engage  independent  counsel and such other
            advisors  it  deems   necessary   or  advisable  to  carry  out  its
            responsibilities  and powers, and, if such counsel or other advisors
            are engaged,  shall  determine the  compensation  or fees payable to

            auditor,  and  review  with the  Board,  the  legal  and  regulatory
            requirements  applicable to the Company and its subsidiaries and the
            Company's   compliance   with   such   requirements.   After   these
            discussions,  the Audit  Committee  may, if it  determines  it to be
            appropriate,  make  recommendations to the Board with respect to the
            Company's   policies  and  procedures   regarding   compliance  with
            applicable laws and regulations.

      o     The Audit  Committee  may  discuss  with  management  legal  matters
            (including  pending  or  threatened  litigation)  that  may  have  a
            material  effect  on  the  Company's  financial  statements  or  its
            compliance policies and procedures.

      C.    Conflicts of Interest

      o     The Audit  Committee  shall  conduct  an  appropriate  review of all
            related  party  transactions  for  potential  conflict  of  interest
            situations  on an  ongoing  basis,  and the  approval  of the  Audit
            Committee shall be required for all such transactions.

      D.    General

      o     The Audit Committee may form and delegate authority to subcommittees
            consisting  of one of more of its  members  as the  Audit  Committee
            deems appropriate to carry out its responsibilities and exercise its
            powers.

      o     The Audit  Committee  may  perform  such other  oversight  functions
            outside of its stated  purpose as may be requested by the Board from
            time to time.

      o     In performing its oversight  function,  the Audit Committee shall be
            entitled to rely upon advice and information that it receives in its
            discussions  and  communications  with  management,  the independent
            auditor  and such  experts,  advisors  and  professionals  as may be
            consulted with by the Audit Committee.

      o     The Audit  Committee  is  authorized  to request that any officer or
            employee of the Company,  the Company's  outside legal 


                                       38


            counsel, the Company's independent auditor or any other professional
            retained  by the Company to render  advice to the  Company  attend a
            meeting  of the  Audit  Committee  or meet  with any  members  of or
            advisors to the Audit Committee.

      o     The  Audit   Committee  is   authorized   to  incur  such   ordinary
            administrative  expenses as are necessary or appropriate in carrying
            out its duties.

Notwithstanding the responsibilities and powers of the Audit Committee set forth
in this  Charter,  the  Audit  Committee  does not have  the  responsibility  of
planning  or  conducting  audits  of  the  Company's  financial   statements  or
determining  whether the Company's financial  statements are complete,  accurate
and in accordance  with GAAP. Such  responsibilities  are the duty of management
and, to the extent of the  independent  auditor's  audit  responsibilities,  the
independent auditor.
