                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

We are a  development  stage  pharmaceutical  company that focuses on developing
compounds to treat respiratory  diseases that affect the ability of the lungs to
absorb  oxygen.  We  are  initially   developing  our  lead  product  candidate,
Surfaxin(R),  for use by newborn infants to treat two respiratory  conditions in
critical  care units of  hospitals.  We are also  developing  this lead  product
candidate for the  treatment of acute  respiratory  distress  syndrome and acute
lung injury in adult patients.  We believe we can use Surfaxin(R) to treat other
respiratory  conditions.  These include asthma,  chronic  obstructive  pulmonary
disease,  emphysema  and cystic  fibrosis.  In  addition,  we believe we can use
Surfaxin(R)  to deliver drugs that are currently  delivered by injection.  These
drugs include antibiotics, pulmonary vasodilators,  brochodilators, steroids and
proteins.  We are also evaluating acquiring licenses to other drug candidates in
the early stage of development for the treatment of respiratory diseases. We may
develop and market our products on our own or seek to enter into  collaborations
with corporate partners for manufacturing and marketing these drugs.

Our lead product is  Surfaxin(R).  Surfaxin(R) is a formulation of an artificial
lung surfactant  containing a peptide or small protein. We patterned Surfaxin(R)
after a human surfactant  protein.  Surfactants are substances that are produced
in the lungs. They possess the ability to lower the surface tension of the fluid
normally  present  within  the air sacs  that are  inside of the  lungs.  In the
absence of sufficient surfactants, these air sacs tend to collapse. As a result,
the lungs do not absorb sufficient oxygen.

We  intend  to  use  Surfaxin(R)  for  the  treatment  of  several   respiratory
conditions.  Currently,  we are  developing  Surfaxin(R)  for the  treatment  of
respiratory distress syndrome in premature infants, meconium aspiration syndrome
in full-term  infants and  respiratory  distress  syndrome and acute lung injury
acute  respiratory  distress  syndrome in adults.  We have also begun developing
Surfaxin(R) to treat other respiratory disorders.

Respiratory distress syndrome is a condition in which premature infants are born
with an insufficient amount of their own natural surfactant. Meconium aspiration
syndrome  is a  similar  condition,  in which  full-term  infants  are born with
meconium in their lungs which  depletes the natural  surfactant  in their lungs.
Meconium is the baby's first bowel movement in the mother's womb. This condition
can lead to meconium  aspiration  syndrome if the baby breathes in the meconium.
Both of these conditions can be  life-threatening  as a result of the failure of
the lungs to absorb sufficient oxygen. These conditions can also deplete natural
surfactants in the lungs.  This results in the need for  mechanical  ventilation
and can be life-threatening. Acute respiratory distress syndrome can result from
a variety  of  events.  Some of these  events are  pneumonia,  breathing  in the
contents of the  stomach,  trauma,  smoke  inhalation,  near  drowning  and head
injury.

The  incidence  of ARDS/ALI is  approximately  240,000  patients per year in the
United States.  Respiratory  distress  syndrome affects 40,000 to 50,000 infants
per  year in the  United  States.  Twenty  to  forty  percent  of  infants  with
respiratory  distress  syndrome  require  extended  mechanical  ventilation  and
hospitalization.  Meconium  aspiration  syndrome  affects  approximately  26,000
newborn infants per year in the United States.

Presently,  the FDA has  only  approved  replacement  surfactants  for  treating
respiratory  distress syndrome in premature infants.  These approved replacement
surfactants come from pigs and



                                       4

cows. Surfaxin(R) is a synthetic surfactant. As a result, we believe that we can
manufacture   Surfaxin(R)  less   expensively.   In  addition  we  believe  that
Surfaxin(R) might possess other pharmaceutical  benefits not possessed by animal
surfactants.  The FDA has not approved replacement  surfactants for treatment of
meconium  aspiration syndrome and acute respiratory  distress syndrome.  The FDA
has granted meconium aspiration syndrome and acute respiratory distress syndrome
fast track  designation.  Fast track  status does not  accelerate  the  clinical
trials nor does it mean that the  regulatory  requirements  are less  stringent.
However,  the FDA will review the New Drug  Application  for a drug granted fast
track status  within six months.  The FDA has awarded us an orphan drug grant to
support our development of Surfaxin(R) in meconium aspiration syndrome.

We also intend to begin preclinical research into converting Surfaxin(R) into an
aerosol  spray  for the  treatment  of  asthma,  chronic  obstructive  pulmonary
disease,  acute  and  chronic  bronchitis  and a  variety  of other  respiratory
diseases.

Our  second  compound  under  development  is  SuperVent(TM)  . We intend to use
SuperVent(TM)  to treat  airway  diseases  such as cystic  fibrosis  and chronic
bronchitis. We deliver SuperVentTM to patients using a nebulizer. A nebulizer is
a device that turns liquid into mist, making it breathable.  We anticipate using
SuperVentTM  for  the  treatment  of  lung  conditions  involving  inflammation,
excessive  mucous and injurious  oxidation.  Injurious  oxidation is a condition
where atoms in tissue lose electrons, which can result in damage to the tissue.

Cystic  fibrosis is a  progressive,  lethal  respiratory  disease that  afflicts
approximately  23,000  patients in the United States and a comparable  number in
Europe.  Cystic  fibrosis  is the  most  common  lethal  genetic  disease  among
Caucasians.  Because of this genetic  defect,  mucus  accumulates  and clogs the
lungs, impairing breathing. This can lead to gradual destruction of the lungs of
cystic fibrosis  patients.  The inability to clear mucus from the lungs can lead
to  blockage  of the  airways in the lungs.  A new  therapy  that is intended to
minimize the  complications  of cystic fibrosis could have a major impact on the
length and quality of life of its patients.

We  are  conducting   clinical  trials  of  Surfaxin(R)  for  the  treatment  of
respiratory   distress  syndrome,   meconium   aspiration   syndrome  and  acute
respiratory distress syndrome. In addition, we are conducting clinical trials of
SuperVentTM for treatment of cystic fibrosis.

PRODUCTS AND TECHNOLOGIES UNDER DEVELOPMENT

SURFAXIN(R)

The Company's lead product is Surfaxin(R),  a  protein-phospholipid  formulation
containing the proprietary,  synthetic peptide sinapultide, for the treatment of
several conditions  characterized by insufficient  surfactant.  Lung surfactants
are  protein-phospholipid  complexes  which coat the  alveoli  (air sacs) of the
lungs.  Lung surfactants lower surface tension in expiration and raise it during
inspiration  to prevent the  collapse of alveoli.  Replacement  surfactants  are
currently approved only for treating idiopathic respiratory distress syndrome in
premature babies ("RDS").  Infants with this condition,  as well as infants born
with meconium (a component of the fetal bowel) in their lungs, which can lead to
meconium  aspiration  syndrome  ("MAS"),   typically  suffer  from  insufficient
surfactant.  This  condition  can lead to a  life-threatening  loss of pulmonary
function.   Patients  with  ARDS/ALI,   which  can  result  from  trauma,  smoke
inhalation,  head injury,  pneumonia  and a variety of other  events,  typically
suffer from  surfactant  deficiency as well. If Surfaxin(R) can be formulated as
an aerosol, it might have utility in other pulmonary disorders, such as asthma.


                                       5
<PAGE>


Surfaxin(R) is an aqueous  suspension of lipids  containing the novel  synthetic
peptide sinapultide.  Surfaxin(R) was invented at The Scripps Research Institute
("Scripps"). Surfaxin(R) is patterned after human Surfactant Protein B, shown to
have the greatest  surfactant  activity in humans.  The product was  exclusively
licensed by Scripps to Johnson & Johnson, Inc. ("J&J"), which, together with its
wholly owned subsidiary,  Ortho Pharmaceutical Corporation ("Ortho"), engaged in
development  activities  with respect to sinapultide.  The Company  acquired the
exclusive worldwide sublicense to the sinapultide  technology from J&J and Ortho
in October 1996.

In July 1992,  an  investigational  new drug  application  ("IND")  submitted by
Scripps  relating  to the use of  Surfaxin(R)  to treat RDS was  approved by the
United  States  Food and  Drug  Administration  (the  "FDA").  J&J  subsequently
completed a  multi-center,  Phase 2 clinical  trial of Surfaxin(R) in 47 infants
with RDS. This trial demonstrated safety and efficacy. In September 1994, an IND
was  submitted by J&J relating to the use of  Surfaxin(R)  to treat ARDS and was
subsequently  approved  by the FDA.  Both the RDS IND and the ARDS IND have been
transferred to the Company.  The Company  subsequently  received FDA approval to
amend  the  approved  ARDS  IND and  re-initiate  Phase  1  clinical  trials  of
Surfaxin(R)  for the treatment of ARDS. The Company amended the existing RDS IND
to permit the initiation of a Phase 2 clinical trial of Surfaxin(R) to treat MAS
on May 27, 1997 at Thomas Jefferson  University  Hospital in Philadelphia.  This
trial was completed and results were  announced on February 4, 1999. The Company
initiated a pivotal Phase 3 trial in MAS in January  2000.  The trial intends to
enroll 200 MAS  patients.  The  Company is engaged in  discussions  with the FDA
concerning a protocol for Phase 3 clinical  trials for  Surfaxin(R) for RDS. The
Company  intends to  commence  the Phase 3 clinical  trial upon  approval of the
protocol  on terms  acceptable  to the  Company.  The Company  also  commenced a
pivotal  Phase 2/3  clinical  trial in  ARDS/ALI  in July  1998.  This trial was
stopped on January 27, 2000 due to the Company's cash position and so that a new
Phase 2 ARDS/ALI trial could be commenced using a new, less viscous  formulation
of  Surfaxin(R).  A new  Phase 2 trial is  currently  being  planned,  which the
Company  expects to commence  following  submission of a protocol and subsequent
approval by the FDA.

SuperVent(TM)

The   Company   is   developing   SuperVent(TM)   as  a   stable,   aerosolized,
multidimensional  therapy for airway diseases such as cystic fibrosis ("CF") and
chronic bronchitis, which are characterized by inflammation, injurious oxidation
and excessive  sputum.  CF results from a genetic  defect in the CFTR gene.  The
CFTR gene codes for a membrane protein responsible for the transport of chloride
ions.  Because of this  genetic  defect,  CF mucus is  excessively  viscous  and
adherent  to  airway  walls.  Destruction  of the  lungs of CF  patients  occurs
gradually  as the  inability  to clear mucus from the lungs leads to blockage of
the airways usually beginning in the smaller airways and alveoli. A new therapy,
which minimizes the pulmonary  complications of CF, would have a major impact on
the length and quality of life of its patients.

SuperVent(TM)'s  active component is tyloxapol, a compound which has been safely
used  as an  emulsifying  agent  in  drug  formulations  by  the  United  States
pharmaceutical  industry for over 40 years.  Experimental  research conducted by
consultants  to the Company  indicates  that  tyloxapol  may possess  biological
activities  beyond  its  well-recognized  emulsification  properties.  In  vitro
studies  conducted  by the  inventors  demonstrated  that  tyloxapol  has  three
mechanisms  of action:  anti-inflammatory  activity,  anti-oxidant  activity and
mucoactive  activity.  This  combination  of  pharmacological  activities is not
presently  found  in any  single,  safe,  effective  therapy  for CF or  chronic
bronchitis in the United States.


                                       6
<PAGE>


The Company's  clinical  development plan for SuperVent(TM) is to focus first on
CF. In September  1995,  the FDA approved a  physician-sponsored  IND to begin a
clinical trial of  SuperVent(TM)  for use in treating CF. The trial commenced on
March 17, 1997 at the University of Utah Health  Sciences Center and is designed
to determine whether aerosolized  SuperVent(TM) holds promise as a low toxicity,
anti-inflammatory,  anti-oxidant  and  mucolytic  agent for the treatment of CF.
Part A of such clinical  trial was completed on March 31, 1998. The results from
this  clinical  trial in  normal  healthy  volunteers  have  indicated  that the
compound had no significant effects on any objective measure of safety (although
coughing was noted by several subjects at the highest doses tested). The Company
began a Phase 2A clinical  trial of  SuperVent(TM)  for the  treatment  of CF on
August  4,  1999.  Preliminary  analysis  of the data  show  that  SuperVent(TM)
decreased the amount of  Interleukin 8 (IL-8) in the sputum of treated  patients
compared  to  controls.  IL-8 is an  important  body  chemical  that  causes the
migration of  inflammatory  cells to the site of release.  The Phase 2A clinical
trial  involved  8  patients  and an  additional  Phase 2 trial  will  likely be
required prior to commencement of a Phase 3 trial.

DSC-103

The Company is developing DSC-103 (formerly known as ST-630) for use in treating
postmenopausal  osteoporosis.   Postmenopausal  osteoporosis  is  a  disease  of
postmenopausal women characterized by decreased bone mass which leads to reduced
bone strength and an increased  risk of  fractures.  DSC-103 is an analog of the
active  circulating  vitamin D hormone,  calcitriol,  modified to  increase  its
potency and lengthen its circulating  half-life.  As a class,  vitamin D analogs
are commonly used therapies in Europe and Japan for osteoporosis.  In aggregate,
this class of compounds is believed to generate  several hundred million dollars
in worldwide sales for osteoporosis.

Published studies have confirmed the efficacy of vitamin D analogs in increasing
bone mass and decreasing  fractures.  Vitamin D analogs,  however, have not been
well  accepted in the United States due to certain side effects in the compounds
currently marketed.  Specifically,  prior studies of vitamin D analogs have been
associated  with  hypercalcemia  in a percentage of patients.  Hypercalcemia  is
elevated  calcium  levels in the blood  above a  generally  accepted  range.  No
vitamin D analogs are currently marketed for osteoporosis in the United States.

In  November  1997,  the Company  filed an IND with the FDA to initiate  Phase 1
clinical studies of DSC-103 as a once-daily,  orally  administered  drug for the
treatment of  postmenopausal  osteoporosis in the United States.  On December 5,
1997, the Company initiated an initial safety and dose-ranging  study of DSC-103
in healthy  normal  volunteers and  postmenopausal  women either with or without
osteoporosis at Covance Clinical Research Unit Inc. in Madison,  Wisconsin.  The
Company  completed  that  clinical  study and  determined  that DSC-103 does not
represent  a  risk  of  hypercalcemia  at  any  dosage  levels  that  may  prove
efficacious for treating postmenopausal osteoporosis.  The Company has access to
preclinical   data   generated   by   Sumitomo    Pharmaceuticals   and   Taisho
Pharmaceuticals  with respect to DSC-103  pursuant to the terms of the licensing
arrangements described herein.

Because  DSC-103 does not meet the critical care focus of  Discovery,  it is the
Company's intention to seek a pharmaceutical  partner to further develop DSC-103
for metabolic bone diseases.

active compound in SuperVentTM, to treat cystic fibrosis and methods of treating
diseases caused by oxidant species,  such as myocardial  infarction,  stroke and
ARDS.  The two pending  United States patent  applications  relate to the use of
tyloxapol as an anti-inflammatory and anti-oxidant agent.

Tyloxapol,  the active  compound  in  SuperVentTM  was the  subject of an issued
United States  composition  of matter patent which expired in 1965.  The patents
and patent applications  licensed to the Company differ from the expired patent,
inter alia, in that one patent  application  covers  proprietary  pharmaceutical
formulations  containing high  concentrations of tyloxapol and the other patents
and patent  applications  cover uses of  tyloxapol  to treat  certain  diseases.
Although the Company believes that high concentration  formulations of tyloxapol
will represent the most practical  means to deliver the active  compound,  there
can be no assurance that any patent  application  covering this formulation will
issue  or that  the  compound  will  not  prove  similarly  effective  in  lower
concentrations   which  are  not  covered  by  any  of  the   Company's   patent
applications.

WARF License Agreement: DSC-103

Pursuant to an  agreement  (the "WARF  License  Agreement")  with the  Wisconsin
Alumni Research Foundation ("WARF"), the Company has an exclusive license within
all countries in the Western  hemisphere in the field of prevention,  treatment,
amelioration  or cure of bone  disease,  under U.S.  Patent No.  4,358,406  (the
"DSC-103  Patent")  covering the compound  DSC-103 and U.S. Patent No. 5,571,802
(the  "DSC-103  Use  Patent")  covering  a method  for  treating  postmenopausal
osteoporosis.  In  addition,  the Company  has  options to extend the  exclusive
license to the remaining countries of the world with the exception of Japan. The
Company options expire on January 1, 2002.

The DSC-103 Patent will expire in July 2001, which the Company  anticipates will
be prior to receipt of any marketing  approval for DSC-103 in the United States.
The DSC-103 Use Patent,  which expires in 2014, is limited to claims relating to
a method of treating  postmenopausal  osteoporosis in humans having such disease
with an effective dosage of DSC-103. These claims do not include claims relating
to the  use of  DSC-103  to  treat  other  metabolic  bone  disorders,  such  as
age-related   osteoporosis   (which   occurs  in  men  and   women)   and  renal
osteodystrophy.  At the Company's  request,  WARF filed an application to pursue
additional  claims  relating to the use of DSC-103 to treat other metabolic bone
diseases.  However,  there can be no assurance that any patent  containing  such
additional  claims will issue in the United States or  elsewhere.  United States
and foreign patents  covering certain  processes  relating to the manufacture of
vitamin D analogs, which have been nonexclusively  licensed to the Company under
the WARF License Agreement, will expire on various dates up to 2005.

Scripps Agreement

The Company and Scripps  were  parties to a sponsored  research  agreement  (the
"Sponsored  Research  Agreement")  that expired during February 1999 pursuant to
which the Company contributed  $460,000 to Scripps' Surfaxin(R) research efforts
per annum.  In March 2000,  the Company and Scripps  entered  into an  Agreement
extending the term for one year commencing  March 1, 2000 and for additional one
year terms upon agreement of the parties.  The Company will contribute  $247,731
per annum to Scripps' Surfaxin(R) research under the Agreement.  The Company has
an option to acquire an  exclusive  worldwide  license to  technology  developed
under the agreement  prior to its  expiration,  which it is required to exercise
within 180 days from receipt of notice from Scripps of the  development  of such
technology. The Company has not received any notice of development of technology
pursuant to the Sponsored  Research  Agreement.  Scripps will own all technology
that it  developed  pursuant  to work  performed  under the  Sponsored  Research
Agreement.  The Company  has the right to receive 50% of the net royalty  income
received by Scripps for inventions  jointly developed by the Company and Scripps
to the extent the Company  does not  exercise  its option  with  respect to such
inventions.

Collaboration Agreements

The Company  entered  into a  sublicense  agreement  with  Laboratorios  del Dr.
Esteve,  S.A.  ("Laboratorios Dr. Esteve") pursuant to which the Company granted
to Laboratorios  Dr. Esteve an exclusive  license to market and sell Surfaxin(R)
products in southern  Europe  (other than Italy),  Central and South America and
Mexico,  with an option to acquire an exclusive  license for Italy. In addition,
the Company granted to Laboratorios Dr. Esteve a right of first negotiation with
respect to other products  developed by the Company for distribution and sale in
the licensed  territory.  Under the  sublicense  agreement,  the Company will be
entitled to  milestone  payments  upon  achievement  of certain  milestones.  In
addition,  the Company entered into a supply


                                       9
<PAGE>


agreement with Dr. Esteve  pursuant to which  Laboratorios  Dr. Esteve agreed to
purchase all of its requirements  (subject to certain limits) of the Surfaxin(R)
products  from the Company.  The Company will receive a percentage  of the sales
price of the  licensed  products  for the  Surfaxin(R)  products as the purchase
price under the supply agreement.

Risk of Loss of Technology/Technological Uncertainty and Obsolescence

The  Company  must  satisfy  the terms and  conditions  set forth in the license
agreements  described  above in order to retain its license  rights  thereunder,
including  but not limited to diligent  pursuit of product  development  and the
timely  payment of  royalty  fees  (including,  with  respect  to  certain  such
agreements,  minimum royalty payments), milestone payments and other amounts. If
the Company fails to comply with such terms and  conditions as set forth in such
license agreements,  its rights thereunder for individual product  opportunities
could be terminated.

The patent position of firms relying upon  biotechnology is highly uncertain and
involves  complex  legal and factual  questions.  To date,  there has emerged no
consistent  policy  regarding  the  breadth of claims  allowed in  biotechnology
patents or the degree of protection  afforded under such patents.  The Company's
success  will  depend,  in  part,  on  its  ability,  and  the  ability  of  its
licensor(s), to obtain protection for its products and technologies under United
States and foreign  patent laws, to preserve its trade  secrets,  and to operate
without  infringing the  proprietary  rights of third  parties.  The Company has
obtained  rights to certain  patents  and patent  applications  and may,  in the
future,  seek  rights  from  third  parties  to  additional  patents  and patent
applications. There can be no assurance that patent applications relating to the
Company's  potential  products  which have been licensed to date, or that it may
license from others in the future, will result in patents being issued, that any
issued  patents  will  afford  adequate  protection  to  the  Company  or not be
challenged,  invalidated,  infringed or circumvented, or that any rights granted
thereunder  will  afford  additional  competitive  advantages  to  the  Company.
Furthermore,  there  can be no  assurance  that  others  have not  independently
developed,   or  will  not  independently   develop,   similar  products  and/or
technologies,  duplicate any of the Company's  products or technologies,  or, if
patents are issued to, or licensed by, the Company,  design around such patents.
There also can be no assurance that the validity of any of the patents  licensed
to the Company,  would be upheld if  challenged  by others in litigation or that
the Company's activities would not infringe patents owned by others. The Company
could incur substantial costs in defending itself in suits brought against it or
any of its  licensors,  or in suits in which the  Company  may  assert,  against
others,  patents in which the Company has rights.  Should the Company's products
or  technologies  be found to  infringe  patents  issued to third  parties,  the
manufacture,  use, and sale of the Company's  products could be enjoined and the
Company could be required to pay substantial  damages. In addition,  the Company
may be required to obtain  licenses  to patents or other  proprietary  rights of
third parties,  in connection  with the  development and use of its products and
technologies.  No assurance  can be given that any licenses  required  under any
such patents or proprietary  rights would be made available on terms  acceptable
to the Company, if at all.

The Company also relies on trade secrets and proprietary  know-how.  The Company
requires all employees to enter into  confidentiality  agreements  that prohibit
the  disclosure  of  confidential  information  to  third  parties  and  require
disclosure and assignment to the Company of rights to their ideas, developments,
discoveries  and  inventions.  In  addition,  the  Company  seeks to obtain such
agreements from its consultants,  advisors and research collaborators;  however,
such  agreements  may  not be  possible  where  such  persons  are  employed  by
universities or other academic  institutions that require assignment of employee
inventions to them.

THIRD PARTY SUPPLIERS; MANUFACTURING AND MARKETING


                                       10
<PAGE>


To be  successful,  the Company's  products must be  manufactured  in commercial
quantities under good manufacturing practice ("GMP") requirements set by the FDA
at acceptable costs. The FDA periodically inspects  manufacturing  facilities in
the  United  States  in  order  to  assure   compliance   with   applicable  GMP
requirements. Foreign manufacturers also are inspected by the FDA if their drugs
are marketed in the United States.  Failure of the foreign or domestic suppliers
of  Discovery's  products  or  failure  of the  manufacturers  of the  Company's
products to comply with GMP  regulations  or other FDA  regulatory  requirements
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations. The Company does not have any manufacturing
capacity  of its own but  instead  intends to rely on outside  manufacturers  to
produce appropriate  clinical grade material for its use in clinical studies for
certain of its products.

The Company has acquired from J&J  experimental  compounds,  the sinapultide and
manufacturing equipment needed to produce and meet its requirements for clinical
supplies of Surfaxin(R).  In addition, the Company has entered into an agreement
with Taylor Pharmaceuticals,  Inc. for the manufacture of Surfaxin(R) for use in
the Company's planned clinical trials.

The active compound in SuperVent(TM) is presently manufactured for several third
parties  pursuant to GMP  standards  by an affiliate  of  Sanofi-Winthrop,  Inc.
(Sanofi"), a multinational  pharmaceutical  company. Sanofi is the sole supplier
of tyloxapol  with GMP  standard  manufacturing  capabilities  and there are few
alternative non-GMP approved sources of supply. Currently, the Company purchases
bulk tyloxapol  from Sanofi on an as-needed  basis.  Although  Sanofi has sold a
quantity of tyloxapol  sufficient for the Company's  proposed Phase 1/2 clinical
trial of  SuperVentTM,  the Company  does not have an  agreement  with Sanofi to
supply any  additional  material,  either in connection  with a Phase 3 clinical
trial or, following  regulatory approval,  for marketing purposes.  In addition,
the  Company  does not  intend  to enter  into an  agreement  for  supply of the
formulated  drug  containing  tyloxapol  unless it plans to  initiate  a Phase 3
clinical  trial of tyloxapol  for the treatment of CF. There can be no assurance
that the Company will be able to enter into a supply  agreement with Sanofi or a
supplier of the formulated drug on terms  acceptable to the Company,  if at all.
In such case,  the Company  would be required  to seek  alternate  manufacturing
sources capable of producing  tyloxapol and the formulated drug. There can be no
assurance  that  the  Company  will  be  able  to  identify  and  contract  with
alternative manufacturers on terms acceptable to it, if at all. Any interruption
in the supply of tyloxapol would have a material adverse effect on the Company's
business, financial condition and results of operations.

The Company may elect to market  Surfaxin(R) and SuperVent(TM)  directly or may,
in the  future  seek to enter into  collaboration  agreements  to license  these
products,  if they are  successfully  developed.  The Company  currently  has no
marketing and sales  experience  and no marketing or sales  personnel.  Unless a
sales force is established,  the Company will be dependent on corporate partners
or other entities for the marketing and selling of its products. There can be no
assurance  that  the  Company  will be  able  to  enter  into  any  satisfactory
arrangements for the marketing and selling of its products. The inability of the
Company to enter into such  third  party  distribution,  marketing  and  selling
arrangements  for its anticipated  products could have a material adverse effect
on the Company's business, financial condition and results of operations.

COMPETITION

The Company is engaged in highly competitive fields of pharmaceutical  research.
Competition from numerous  existing  companies and others entering the fields in
which the  Company  operates is intense and  expected to  increase.  The Company
expects to compete with, among others,  conventional  pharmaceutical  companies.
Most of these companies have  substantially  greater  research and  development,
manufacturing,  marketing,  financial,  technological,  personnel and managerial
resources  than  the  Company.  Acquisitions  of  competing  companies  by large
pharmaceutical  or health care companies could further enhance such competitors'
financial, marketing and other resources. Moreover, competitors that are able to
complete  clinical  trials,  obtain required  regulatory  approvals and commence
commercial  sales of their products before The Company could enjoy a significant
competitive advantage. There are also existing therapies that may be expected to
compete with the Company's products under development.

Presently,  there are no approved drugs that are specifically  indicated for MAS
or ARDS/ALI.  Current therapy consists of general supportive care and mechanical
ventilation.  Four products are specifically  approved for the treatment of RDS.
CurosurfTM,  marketed in Europe by Ares-Serono and Chiesi,  and in the US by Dey
Labs, is a porcine lung extract. ExosurfTM, marketed by Glaxo Wellcome, contains
only phospholipids and synthetic organic  detergents and no stabilizing  protein
or  peptides.  SurvantaTM,  which  has  been  shown  to be more  effective  than
ExosurfTM in clinical trials, is an extract of bovine lung that contains the cow
version of Surfactant  Protein B.  Recently,  Forest  Laboratories  has obtained
marketing clearance from the FDA for its calf lung surfactant,  InfasurfTM,  for
use in RDS.  Although none of the four approved  surfactants for RDS is approved
for ARDS or ALI, which are significantly larger markets, there are a significant
number of other potential therapies in development for the treatment of ARDS/ALI
that are not  surfactant  related.  Any of these  various drugs or devices could
significantly  impact the commercial  opportunity for  Surfaxin(R).  The Company
believes  that  synthetic  surfactants  such as  Surfaxin(R)  will  be far  less
expensive to produce than the animal-derived products approved for the treatment
of RDS.

Genentech  has  marketed  PulmozymeTM  in the  United  States and Canada as a CF
therapy  since early 1994.  PulmozymeTM  reduces  the  viscosity  of CF mucus by
cleaving the DNA released from destroyed inflammatory,  epithelial and bacterial
cells  which  collect in mucus and  contribute  to its  abnormal  viscosity  and
adherence.  The approximate yearly cost of PulmozymeTM  treatment for an average
patient is $12,000. The Company believe that the high cost of this treatment may
reduce its competitive profile as compared with SuperVent(TM).

There are numerous approved  therapies for osteoporosis  which will compete with
DSC-103. Such therapies include estrogen, which is of proven benefit in treating
osteoporosis in postmenopausal women, but is associated with significant adverse
effects  (including  increased  breast  and  uterine  cancer  risk);   FosamaxTM
(alendronate),  a drug of the bisphosphonate class marketed by Merck; EvistaTM a
selective estrogen receptor modulator marketed by Eli Lilly; and MiacalcinTM,  a
nasally administered calcitonin marketed by Sandoz Pharmaceuticals. In addition,
there are a number of therapies in development for osteoporosis that potentially
will compete with DSC-103.

GOVERNMENT REGULATION

The  testing,  manufacture,  distribution,  advertising  and  marketing  of drug
products are subject to extensive regulation by governmental  authorities in the
United  States  and other  countries.  Prior to  marketing,  any  pharmaceutical
products  developed  or  licensed  by the  Company  must  undergo


                                       12
<PAGE>

an extensive  regulatory  approval process required by the FDA and by comparable
agencies in other countries.  This process,  which includes  preclinical studies
and clinical trials of each pharmaceutical  compound to establish its safety and
efficacy  and  confirmation  by the  FDA  that  good  laboratory,  clinical  and
manufacturing  practices were maintained during testing and  manufacturing,  can
take many years,  requires the  expenditure of  substantial  resources and gives
larger companies with greater financial  resources a competitive  advantage over
the Company.  The FDA review process can be lengthy and  unpredictable,  and the
Company may encounter delays or rejections of its  applications  when submitted.
If  questions  arise  during  the  FDA  review  process,  approval  may  take  a
significantly longer period of time. Generally, in order to gain FDA approval, a
company  first must conduct  preclinical  studies in a laboratory  and in animal
models  to  obtain  preliminary  information  on a  compound's  efficacy  and to
identify any safety problems. The results of these studies are submitted as part
of an IND  application  that the FDA must review before human clinical trials of
an investigational drug can start.

Clinical trials are normally done in three phases and generally take two to five
years or longer to complete.  Typically, clinical testing involves a three-phase
process.  Phase 1 consists  of  testing  the drug  product in a small  number of
humans to  determine  preliminary  safety  and  tolerable  dose  range.  Phase 2
involves  larger  studies to evaluate the  effectiveness  of the drug product in
humans  having  the  disease  or  medical  condition  for which the  product  is
indicated and to identify  possible  common adverse effects in a larger group of
subjects.  Phase 3  consists  of  additional  controlled  testing  to  establish
clinical  safety  and  effectiveness  in  an  expanded  patient   population  of
geographically  dispersed  test  sites,  to evaluate  the  overall  benefit-risk
relationship for  administering the product and to provide an adequate basis for
product labeling.

After  completion  of  clinical  trials of a new drug  product,  FDA and foreign
regulatory authority marketing approval must be obtained. A New Drug Application
("NDA")  submitted  to the FDA  generally  takes  one to three  years to  obtain
approval. If questions arise during the FDA review process,  approval may take a
significantly  longer period of time. The testing and approval processes require
substantial time and effort and there can be no assurance that any approval will
be granted on a timely  basis,  if at all.  Even if  regulatory  clearances  are
obtained, a marketed product is subject to continual review, and later discovery
of  previously  unknown  problems  or  failure  to  comply  with the  applicable
regulatory requirements may result in restrictions on the marketing of a product
or  withdrawal  of the  product  from the  market as well as  possible  civil or
criminal  sanctions.  For marketing outside the United States,  the Company also
will be subject to foreign  regulatory  requirements  governing  human  clinical
trials and marketing  approval for  pharmaceutical  products.  The  requirements
governing  the  conduct of  clinical  trials,  product  licensing,  pricing  and
reimbursement  vary  widely  from  country  to  country.  None of the  Company's
products under development have been approved for marketing in the United States
or elsewhere.  No assurance can be given that the Company will be able to obtain
regulatory  approval for any such products under development.  Failure to obtain
requisite  governmental  approvals  or failure to obtain  approvals of the scope
requested  will delay or preclude  the  Company or its  licensees  or  marketing
partners from  marketing  their  products,  or limit the  commercial  use of the
products,  and thereby  could have a material  adverse  effect on the  Company's
business, financial condition and results of operations.

During October 1998, the FDA granted the Company Fast Track approval  status for
the ARDS/ALI and MAS indications.  Fast track status facilitates the development
and expedites the review of new drugs intended for treatment of life-threatening
conditions  for which there is  presently no medical  option.  The FDA Office of
Orphan Products Development (the "OOPD")


                                       13
<PAGE>


has  designated  Surfaxin(R)  as an  orphan  drug for the  treatment  of MAS and
ARDS/ALI.  During  October 1998, the OOPD awarded  Discovery a renewable  Orphan
Products Development Grant, ranging from $194,390 for the first year to $583,170
over three years, to finance the Company's MAS trial.

EMPLOYEES

The Company has 11 full-time employees.  The Company's future success depends in
significant part upon the continued service of its key scientific  personnel and
executive  officers  and its  continuing  ability to attract  and retain  highly
qualified scientific and managerial personnel. Competition for such personnel is
intense  and there can be no  assurance  that the  Company  can  retain  its key
employees or that it can attract,  assimilate  or retain other highly  qualified
technical and managerial personnel in the future.

1998 Merger

On June 16, 1998,  Discovery  completed the acquisition of the then  outstanding
minority  interest  in ATI  through  the merger of a  transitory  subsidiary  of
Discovery with and into ATI (the "1998 Merger").  Upon  consummation of 1998 the
Merger, (i) Dr. Capetola became the Chief Executive Officer of the Company, (ii)
the other  members of ATI's  management  team prior to the 1998  Merger  assumed
executive  positions with the Company comparable to their present positions with
ATI and (iii) the Board of Directors of Discovery was  reconstituted  to consist
of its present members.

1997 Merger

On November 25, 1997, Old Discovery was merged (the "1997 Merger") with and into
the Company.  Pursuant to the 1997  Merger,  the name of the Company was changed
from Ansan  Pharmaceuticals,  Inc. to Discovery  Laboratories,  Inc. Immediately
following the  consummation of the 1997 Merger,  the Company  effected a 1-for-3
reverse split (the "Reverse Split") of the outstanding Common Stock.

IMPORTANT FACTORS REGARDING THE COMPANY

The following important factors,  among others, could cause the Company's actual
results,  performance,  achievements,  or industry results to differ  materially
from those  expressed  in the  Company's  forward-looking  statements  contained
herein and presented elsewhere by management from time to time.

Because We Are a Development Stage Company, We May Not Successfully  Develop and
Market Our Products,  and Even If We Do, We May Not Generate  Enough  Revenue or
Become Profitable.

We are a development stage company.  Therefore, you must evaluate us in light of
the uncertainties and complexities  present in a development stage biotechnology
company.  We are conducting  research and development on our product candidates.
Accordingly,  we have  not  begun  to  market  or  generate  revenues  from  the
commercialization  of  any  of  these  products.  We  will  need  to  engage  in
significant,  time-consuming  and  costly  research,  development,  pre-clinical
studies,  clinical  testing  and  regulatory  approval  for our  products  under
development  prior to their  commercialization.  In  addition,  pre-clinical  or
clinical studies may show that our products are not effective or safe for one or
more  of   their   intended   uses.   We  may  fail  in  the   development   and
commercialization  of our products.  We expect to incur  significant  increasing
operating  losses over the next several years.  If we succeed in the development
of our products,  we still cannot


                                       14
<PAGE>


assure you that we will generate  sufficient or sustainable  revenues or that we
will be profitable.

The Types of Products We Are  Developing Are Subject to Risks That Are Difficult
to Foresee, and We May Not Succeed In Our Development Efforts.

Our  development of products is subject to the risks of failure  inherent in the
development  of new  pharmaceutical  products  which  utilize  innovative or new
technologies.  During the development  process,  we could experience  unforeseen
problems that could delay us from completing the development of our products. As
a result,  we may terminate  development of these products or  applications.  We
cannot assure you:
              -- that we will succeed in our research and  development;
              -- that we will successfully market our proposed products.

If We Cannot Raise  Additional  Capital We Will Need to Discontinue Our Research
and Development  Activities.  In Addition, Any Additional Financing Could Result
in Dilution.

We will need substantial  additional funding to conduct our research and product
development  activities  and, if we are  successful,  to manufacture  and market
products.  We intend  to raise  further  funds  through  collaborative  ventures
entered into with potential  corporate  partners and through  additional debt or
equity  financings.  We may in some cases  elect to develop  products on our own
instead of entering into  collaboration  arrangements.  This would  increase our
cash requirements for research and development. We cannot provide assurance that
we will obtain  necessary  financing.  We have not entered into  arrangements to
obtain  any  additional  financing.   Any  additional  financing  could  include
unattractive terms or result in significant dilution of stockholders' interests.
If we fail  to  enter  into  collaborative  ventures  or to  receive  additional
funding, we would have to scale back or discontinue our research and development
operations. Furthermore, we could cease to qualify for listing of our securities
on the Nasdaq  SmallCap  Market.  See "We Face the Possibility of Delisting From
the Nasdaq SmallCap Market."

If We Fail to Obtain Regulatory Approval to Commercially Manufacture or Sell Any
of Our  Products or If the FDA Delays  Approval of Our  Product  Candidates,  it
Could Increase the Cost of Product  Development  or Ultimately  Prevent or Delay
Our Ability to Sell Our Products and Generate Revenues.

In order to sell  our  products  that are  under  development,  we must  receive
regulatory  approvals  for our  products.  The FDA and  comparable  agencies  in
foreign countries extensively and rigorously regulate the testing,  manufacture,
distribution,  advertising,  pricing and marketing of drug products. The FDA and
comparable agencies in other countries require an extensive  regulatory approval
process  before we can market our  product.  This process  includes  preclinical
studies and clinical  trials of each  pharmaceutical  compound to establish  its
safety  and  effectiveness  and  confirmation  by the FDA that the  manufacturer
maintains good laboratory,  clinical and manufacturing  practices during testing
and manufacturing.  The process is lengthy,  expensive and uncertain. It is also
possible that we may not reach  agreement with the FDA on the design of clinical
studies necessary for approval.  In addition,  conditions  imposed by the FDA on
our  clinical  trials  could  significantly   increase  the  time  required  for
completion  of  clinical  trials and the costs of  conducting  clinical  trials.
Clinical trials generally take two to five years or more to complete.

The testing  and  approval  processes  require the  expenditure  of  substantial
resources. The FDA may not give us the requisite approvals for our products on a
timely basis, if ever. The FDA


                                       15
<PAGE>


could withdraw any approvals we obtain.  Further,  if there is a later discovery
of unknown  problems  or if we fail to comply with other  applicable  regulatory
requirements  at any stage in the  regulatory  process,  the FDA may restrict or
delay our  marketing  of a  product,  or force us to make  product  recalls.  In
addition, the FDA could impose other sanctions such as fines, injunctions, civil
penalties or criminal prosecutions.  For marketing outside the United States, we
also  need to  comply  with  foreign  regulatory  requirements  governing  human
clinical trials and marketing approval for pharmaceutical  products. The FDA and
foreign  regulators have not yet approved any of our products under  development
for marketing in the United States or elsewhere. If the FDA and other regulators
do not approve our products, it could prevent us from marketing our products.

Our Strategy,  In Many Cases,  Is to Enter into  Collaboration  Agreements  with
Third  Parties  with  Respect  to Our  Products  and We May  Require  Additional
Collaboration Agreements. In Addition, If We Enter into These Agreements and the
Third Parties Do Not Perform,  it Could Impair Our Ability to Commercialize  Our
Products.

Our strategy for the completion of the required development and clinical testing
of our products and for the manufacturing,  marketing and  commercialization  of
our  products,   in  many  cases,   depends  upon  entering  into  collaboration
arrangements with  pharmaceutical  companies.  We have entered into a sublicense
agreement for Surfaxin(R)  covering  southern  Europe and Latin America.  We may
need to enter into additional collaboration  agreements.  Our success may depend
upon obtaining partners.  In addition,  we may depend on our partners' expertise
and dedication of sufficient resources to develop and commercialize our proposed
products. We may in the future grant to collaboration partners rights to license
and  commercialize   pharmaceutical   products  developed  under   collaboration
agreements.  Under these arrangements our collaboration partners may control key
decisions relating to the development of the products.  Those rights would limit
our flexibility in considering  alternatives  for the  commercialization  of our
products.  If we fail to  successfully  develop  these  relationships  or if our
collaboration partners fail to develop or commercialize  successfully any of our
products,  it may delay or prevent us from  developing  or  commercializing  our
products in a competitive and timely manner.

Discoveries or Developments of New Technologies by Our Competitors or Others May
Make Our Products less Competitive or Make Our Products Obsolete.

There are rapidly changing  technologies and evolving industry  standards in the
biotechnology and pharmaceutical markets. We intend to market our products under
development  for the  treatment  of diseases  for which other  technologies  and
proposed treatments are rapidly  developing.  The research efforts of others may
render our research and product  development  efforts  obsolete.  Third  parties
conducting  research include  governments,  major research  facilities and large
multinational corporations.  Many of the third parties have greater research and
development,  manufacturing,  marketing, financial, technological,  personal and
managerial resources than we have.

If We Cannot Protect Our  Intellectual  Property,  Other Companies Could Use Our
Technology in Competitive  Products.  If We Infringe the  Intellectual  Property
Rights of Others,  Other Companies Could Prevent us from Developing or Marketing
Our Products.

We seek patent  protection for our drug  candidates so as to prevent others from
commercializing   equivalent   products  in  substantially   less  time  and  at
substantially  lower expense.  The pharmaceutical  industry places  considerable
importance on obtaining patent and trade secret


                                       16
<PAGE>


protection for new technologies, products and processes. Our success will depend
in part on our ability and that of parties from whom we license technology to:
              -- defend our patents and otherwise prevent others from infringing
                 on our  proprietary  rights;
              --  protect  trade  secrets;  and
              --  operate without  infringing upon the proprietary rights of
                  others, both in the United States and in other countries.

The patent position of firms relying upon  biotechnology is highly uncertain and
involves complex legal and factual questions.  To date, the United States Patent
and Trademark Office ("USPTO") has not adopted a consistent policy regarding the
breadth of claims that the USPTO allows in  biotechnology  patents or the degree
of protection that these types of patents afford.

Even If We Obtain  Patents to Protect  Our  Products,  Those  Patents May Not Be
Sufficiently Broad and Others Could Compete with Us.

We, or the  parties  licensing  technologies  to us, have filed  various  United
States  and  foreign  patents  applications  with  respect to the  products  and
technologies under our development and the USPTO and foreign patent offices have
issued  patents  with respect to our  products  and  technologies.  These patent
applications   include   international   application   filed  under  the  Patent
Cooperation  Treaty. Our pending patent  applications,  those we may file in the
future or those we may license from third parties may not result in the USPTO or
foreign  patent office  issuing  patents.  Also,  if patent rights  covering our
products are not  sufficiently  broad,  they may not provide us with proprietary
protection or competitive  advantages against  competitors with similar products
and  technologies.  Furthermore,  if the USPTO or foreign  patent  offices issue
patents to us or our  licensors,  others may challenge the patents or circumvent
the  patents,  or the patent  office or the courts may  invalidate  the patents.
Thus,  any  patents we own or license  from third  parties  may not  provide any
protection against  competitors.  In particular,  our issued and pending patents
relating to SuperVent(TM) cover high concentrations of tyloxapol.  These patents
could prove  meaningless if low  concentrations of tyloxapol are as effective as
higher  concentrations  of tyloxapol in treating  the  indications  which we are
developing our SuperVent(TM) product to treat.

Patents Which Others Obtain Could Limit Our Ability to Market Our Products.

Our  commercial  success  also  significantly  depends on our ability to operate
without  infringing the patents or violating the  proprietary  rights of others.
The  USPTO  keeps  United  States  patent  applications  confidential  while the
applications  are pending.  Accordingly,  we cannot  determine which  inventions
third parties claim in pending patent applications which they have filed. We may
need to engage in litigation to defend or enforce our patent and license  rights
or to determine the scope and validity of the proprietary  rights of others.  It
will be expensive and time consuming to defend and enforce patent claims.  Thus,
even in  those  instances  in  which  the  outcome  is  favorable  to us,  these
proceedings can result in the diversion of substantial  resources from our other
activities.  An adverse determination may subject us to significant  liabilities
or  require  us to seek  licenses  that  third  parties  may not grant to us. An
adverse  determination  could also require us to alter our products or processes
or cease altogether any related  research and development  activities or product
sales.


                                       17

If We Cannot Meet Requirements under Our License  Agreements,  We Could Lose Our
Rights to Our Products.

We depend on licensing  arrangements  to maintain  rights to our products  under
development.   These  agreements   require  us  to  make  payments  and  satisfy
performance  obligations  in order to maintain our rights under these  licensing
arrangements.  In  addition,  we are  responsible  for the  cost of  filing  and
prosecuting  patent  applications and maintaining issued patents licensed to us.
If we do not meet our  obligations  under  our  license  agreements  in a timely
manner, we could lose the rights to our proprietary technology.

We Rely on Confidentiality Agreements That Our Employees Could Breach.

We require all employees to enter into confidentiality  agreements that prohibit
the  disclosure  of  confidential  information  to  third  parties  and  require
disclosure and assignment to us of rights to our employees' ideas, developments,
discoveries and inventions while we employ them. In addition,  we seek to obtain
these  types  of  agreements  from  our   consultants,   advisors  and  research
collaborators.  To the extent that  consultants,  key  employees  or other third
parties   apply   technological   information   which  they  or  other   parties
independently develop to any of our proposed projects,  disputes may arise as to
the proprietary  rights to this type of  information.  In such case, a court may
determine that the right belongs to a third party. In addition,  we will rely on
trade secrets and  proprietary  know-how that we will seek to protect in part by
confidentiality agreements with our employees,  consultants, advisors or others.
We cannot assure you:
              --  that they will not breach these agreements; or
              --  that  agreements  we  would  obtain  would  provide   adequate
                  remedies for this type of breach or that our trade  secrets or
                  proprietary  know-how  will  not  otherwise  become  known  or
                  competitors will not independently develop similar technology.

If the Third  Parties  We Depend on for the  Manufacture  of Our  Pharmaceutical
Products Do Not Supply These Products in a Timely Manner, it May Delay or Impair
Our Ability to Develop and Market Our Products.

We rely on outside  manufacturers,  including Taylor  Pharmaceuticals,  Inc., to
produce  appropriate  clinical  grade  material that meets  standards for use in
clinical  studies for our products.  We will also rely on outside  manufacturers
for  production of products  after  marketing  approval.  We may also enter into
arrangements with other manufacturers for the manufacture of material for use in
clinical testing and after marketing approval.

Our outside  manufacturers may not perform as they have agreed or may not remain
in the contract  manufacturing  business for a sufficient  time to  successfully
produce and market our product  candidates.  In this event we may fail to find a
replacement  manufacturer or develop our own manufacturing  capabilities.  If we
cannot do so, it could delay or impair our ability to obtain regulatory approval
for our products. In addition, if we find a replacement manufacturer there could
be a substantial  delay before a new facility  could be qualified and registered
with the FDA and foreign regulatory authorities.

We may in the future elect to manufacture some of our products on our own. We do
not  currently  have  a  manufacturing  facility,  manufacturing  experience  or
manufacturing  personnel. If we determine to manufacture products on our own and
do not successfully develop manufacturing capabilities, it will adversely affect
sales of our products.

In addition, the FDA and foreign regulatory authorities require manufacturers to
register manufacturing facilities.  The FDA and corresponding foreign regulators
inspect these facilities


                                       18
<PAGE>


to confirm compliance with good manufacturing practice requirements that the FDA
or corresponding  foreign regulators  establish.  If our third-party  foreign or
domestic  suppliers or  manufacturers  of our products  fail to comply with good
manufacturing  practice  requirements or other FDA regulatory  requirements,  it
could adversely affect our ability to market our products.

We Do Not Have Marketing and Sales  Experience,  and Our Lack of That Experience
Could Limit Our Ability to Generate Revenues from Future Product Sales.

We do not have marketing and sales  experience or marketing or sales  personnel.
If we do not  develop  a  marketing  and  sales  force,  then we will  depend on
arrangements  with  corporate  partners or other  entities for the marketing and
sale of our  products.  We may not  succeed in  entering  into any  satisfactory
third-party  arrangements  for  the  marketing  and  sale  of our  products.  In
addition,  we may not succeed in developing  marketing and sales capabilities or
we may not have sufficient resources to do so. If we fail to establish marketing
and sales capabilities or fail to enter into arrangements with third parties, it
will adversely affect sales of our products.

We Depend upon Key Employees and Consultants in a Competitive Market for Skilled
Personnel.  If We Are  Unable to  Attract  and  Retain  Key  Personal,  it Could
Adversely Effect Our Ability to Develop and Market Our Products.

We are highly  dependent  upon the  principal  members of our  management  team,
especially Dr. Capetola,  and our directors,  as well as our scientific advisory
board members,  consultants and collaborating  scientists. We have an employment
agreement  with Dr.  Capetola  which  expires  on June 15,  2002.  We also  have
employment  agreements with other key personnel with termination  dates in 2001.
We do not maintain  key-man life  insurance.  The loss of any of these  persons'
services would  adversely  affect our ability to develop and market our products
and obtain necessary regulatory approvals.

Our future success also will depend in part on the continued  service of our key
scientific and management personnel and our ability to identify, hire and retain
additional personnel, including marketing and sales staff. We experience intense
competition for qualified personnel.

While we attempt to provide  competitive  compensation  packages  to attract and
retain  key  personnel,  some of our  competitors  are  likely  to have  greater
resources  and more  experience  than we have,  making  it  difficult  for us to
compete for key personnel.

Our Industry is Highly  Competitive  and We Have less Capital and Resources than
Many of Our  Competitors,  and This May Give Them an Advantage in Developing and
Marketing Products Similar to Ours.

Our industry is highly competitive.  We compete with numerous existing companies
intensely  in many ways.  We expect new  companies  to enter our industry and we
expect  competition  to increase.  Many of these  companies  have  substantially
greater research and development, marketing, financial, technological, personnel
and managerial  resources than we have. In addition,  many of these competitors,
either alone or with their collaborative  partners,  have significantly  greater
experience than we do in:
              --  developing products;
              --  undertaking  preclinical  testing and human clinical trials;
              --  obtaining FDA and other regulatory  approvals or products;
                  and
              --  manufacturing and marketing products.


                                       19
<PAGE>


Accordingly,  our  competitors  may  succeed  in  obtaining  patent  protection,
receiving  FDA approval or  commercializing  products  before us. If we commence
commercial  product  sales,  we will  compete  against  companies  with  greater
marketing and manufacturing  capabilities.  These are areas in which, as yet, we
have limited or no experience.  In addition,  developments  by  competitors  may
render our product  candidates  obsolete or  uncompetitive.  Our competitors may
succeed in developing and marketing products that are more effective than ours.

We  also  face,   and  will  continue  to  face,   competition   from  colleges,
universities,  governmental  agencies  and other  public  and  private  research
organizations.  These  competitors  are becoming  more active in seeking  patent
protection and licensing arrangements to collect royalties for use of technology
that they have developed.  Some of these  technologies may compete directly with
the technologies  that we are developing.  These  institutions will also compete
with us in recruiting  highly  qualified  scientific  personnel.  We expect that
therapeutic  developments  in the  areas in which we are  active  may occur at a
rapid rate and that  competition  will  intensify  as advances in this field are
made.  Accordingly,  we need to continue  to devote  substantial  resources  and
efforts to research and development activities.

If Product  Liability  Claims Are  Brought  Against Us, it May Result in Reduced
Demand for Our Products or Damages That Exceed Our Insurance Coverage.

The marketing and use of our products exposes us to product  liability claims in
the event that the use or misuse of those  products  causes  injury,  disease or
results in adverse effects.  Use of our products in clinical trials,  as well as
commercial sale, could result in product  liability claims. In addition sales of
our products through third party  arrangements  could also subject us to product
liability claims. We presently carry product liability insurance relating to our
clinical  trials of  SuperVent(TM)  and  Surfaxin(R).  However,  this  insurance
coverage  might not  fully  cover any  potential  claims.  We may need to obtain
additional  product  liability  insurance  coverage prior to initiation of other
clinical trials. We expect to obtain product liability insurance coverage before
commercialization of our proposed products; however, this insurance is expensive
and insurance companies may not issue this type of insurance when we need it. We
cannot provide assurance that we can obtain adequate  insurance in the future at
an acceptable cost. Any product liability claim, even one that was not in excess
of our insurance  coverage or one that is meritless,  could adversely affect our
cash  available  for  other  purposes,  such as  research  and  development.  In
addition,  the  existence of a product  liability  claim could affect the market
price of our common stock.

Healthcare  Reform  Measures and  Reimbursement  Procedures  May Prevent Us from
Obtaining an Adequate Level of Reimbursement for Our Products That in Turn Would
Decrease Our Ability to Generate Revenues.

Efforts of governmental and third-party payers to contain or reduce the costs of
health  care  through  various  means could  affect the levels of  revenues  and
profitability of pharmaceutical  and biotechnology  products and companies.  For
example,  in some foreign  markets,  pricing or  profitability  of  prescription
pharmaceuticals is subject to government  control.  In the United States,  there
have  been a  number  of  federal  and  state  proposals  to  implement  similar
government control.  Pricing constraints on our products could negatively impact
our revenues and profitability.


                                       20
<PAGE>


In the United States and elsewhere, successful commercialization of our products
will depend in part on the  availability of  reimbursement to the consumer using
our products from third-party  health care payers such as government and private
insurance plans.  Third-party payors may not provide sufficient reimbursement to
enable us to maintain price levels  sufficient to realize an appropriate  return
on our  investment in product  development.  Third-party  health care payers are
increasingly  challenging  the price and  examining  the  cost-effectiveness  of
medical products and services. If we succeed in bringing one or more products to
market,  and the  government  or  third-party  payers  fail to provide  adequate
coverage or reimbursement rates for those products,  it could reduce our product
sales and product revenues.

Directors,  Executive Officers,  Principal  Stockholders and Affiliated Entities
Own a Significant Percentage of Our Capital Stock, and this Could Have an Effect
on Actions by the Stockholders.

As of March 29, 2000, our directors,  executive officers, principal stockholders
and affiliated entities beneficially own, in the aggregate, approximately 32% of
our outstanding  voting  securities.  Accordingly,  these  stockholders have the
ability  to exert  substantial  influence  over  the  election  of our  Board of
Directors and the outcome of issues requiring approval by our stockholders. This
concentration  of  ownership  may have the effect of  delaying or  preventing  a
change in control.  This could prevent  transactions in which stockholders might
otherwise recover a premium for their shares over current market prices.

We Face the Possibility  that Nasdaq May Delist our Common Stock from the NASDAQ
SmallCap Market.

To meet the  current  listing  requirements  for Nasdaq to  continue to list our
securities on the Nasdaq SmallCap Market, we will have to maintain:
                  (a)      (1) at least $2 million in net tangible assets or
                           (2) $35 million in market capitalization or
                           (3) $500,000 in net income (over two of the last
                               three years),
                  (b) a public  float of at least  500,000  shares  valued at $1
                      million  or more and
                  (c) a minimum  bid price of $1 and
                  (d) at least 300  holders  of our  common  stock and
                  (e) at least two active market makers.

At December 31, 1999,  we had  $3,108,000  in net tangible  assets.  The closing
price of our common  stock  during the period from  January 1, 1999 to March 28,
2000 ranged from $1.00 to $12.63 and the  closing  price of our common  stock on
March 28, 2000 was $8.53.

If we are  unable to satisfy  the  listing  requirements,  Nasdaq may delist our
securities  from the Nasdaq  SmallCap  Market.  If any  trading  markets for our
securities are  available,  investors  could only trade in the  over-the-counter
market in the Pink  Sheets(R)  (a  quotation  medium  operated  by the  National
Quotation Bureau,  LLC), or on the NASD's OTC Bulletin  Board(R).  Consequently,
this would impair the liquidity of our securities.  This could reduce the number
of our securities investors could buy and sell and could result in delays in the
timing of the  transactions,  reduction  in  securities  analysts'  and the news
media's coverage of us and lower prices for our securities.

The "Penny Stock" Rules May Adversely Affect the Liquidity of Our Common Stock.

If Nasdaq delisted our securities from the Nasdaq  SmallCap  Market,  Rule 15g-9
under the Exchange Act would apply. Rule 15g-9 imposes additional sales practice
requirements  on


                                       21
<PAGE>


broker-dealers  that sell  these  types of  securities  to  persons  other  than
established customers and "accredited  investors"  (generally,  individuals with
net worth in excess of  $1,000,000  or annual  incomes  exceeding  $200,000,  or
$300,000 together with their spouses). For transactions that this rule covers, a
broker-dealer  must make a special  suitability  determination for the purchaser
and receive the purchaser's  written  consent to the transaction  prior to sale.
Consequently,  the rule may adversely  affect the ability of  broker-dealers  to
sell our securities and may adversely affect the ability of stockholders to sell
any of our securities in the secondary market.

The Commission has adopted regulations that define a "penny stock". Generally, a
penny stock is an equity security that has a market price of less than $5.00 per
share. For any transaction involving a penny stock that is not exempt, the rules
require that a broker-dealer  deliver a disclosure  schedule that the Commission
has  prepared  relating to the penny stock  market.  The rule also  requires the
broker-dealer  to disclose  information  about  commissions  payable to both the
broker-dealer and the registered  representative  and current quotations for the
securities.   Finally,  rules  require  that  the  broker-dealers  send  monthly
statements  disclosing  recent price information for the penny stock held in the
account and information on the limited market in penny stocks.

These  restrictions  will not apply to our  securities  if the  Nasdaq  SmallCap
Market  continues to list our  securities.  If Nasdaq delists our securities and
they become subject to the existing or proposed rules on penny stocks,  it could
severely adversely affect the market liquidity for our securities.

A  Substantial  Number of Our  Securities  Are Eligible for Future Sale and this
Could Affect the Market Price for Our Stock and Our Ability to Raise Capital.

The market  price of our common  stock could drop due to sales of a large number
of shares of our common stock or the perception that these sales could occur. As
of March 28, 2000, there were  approximately  20,630,290  shares of common stock
outstanding.  In addition, as of March 28, 2000 up to 6,765,313 shares of Common
Stock were issuable on exercise of outstanding options and warrants.

Holders of our stock options and warrants are likely to exercise  them, if ever,
at a time when we otherwise  could obtain a price for the sale of our securities
that is higher than the exercise  price per security of the options or warrants.
This  exercise or the  possibility  of this  exercise  may impede our efforts to
obtain additional  financing  through the sale of additional  securities or make
this financing more costly.

We cannot predict the effect that the availability of these shares for sale will
have on the market price of our common stock. Nevertheless,  because holders may
sell  substantial  amounts of our common stock in the public market,  the market
price of our common stock could drop as a result of sales of these securities or
the  perception  that these types of sales may occur.  These  factors could also
make it more  difficult  for us to  raise  funds  through  future  offerings  of
securities.

Anti-takeover  Provisions of Our Certificate of  Incorporation  and Delaware Law
Could  Delay  Actual  or  Potential  Changes  of  Control,  Which  Could  Affect
Stockholder   Ability  to  Benefit  From  Market  Fluctuations  and  Changes  in
Management.

Our Certificate of Incorporation  and Delaware law contain  provisions which may
discourage  transactions  involving actual or potential changes in control.  Our
Certificate  of  Incorporation  allows  us to issue  shares of  preferred  stock
without any vote or further action by our  shareholders.  Our Board of Directors
has the authority to fix and determine the relative  rights


                                       22
<PAGE>


and  preferences  of  preferred  shares.  Our  Board of  Directors  also has the
authority to issue these  shares  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 on
common stock and the right to the  redemption of these  shares,  together with a
premium,  prior to the redemption of our common stock. In addition, our Board of
Directors,  without further  stockholder  approval,  could issue large blocks of
preferred stock to fend against unwanted tender offers or hostile takeovers.

We are also subject to  provisions of Delaware law that could delay or make more
difficult a merger,  tender offer or proxy contest  involving us. In particular,
we are  subject to Section  203 of the  Delaware  General  Corporation  Law that
prohibits a Delaware  corporation from engaging in any business combination with
any  interested  stockholder  for a period of three  years  unless  the Board of
Directors and stockholders  approve the transactions in a prescribed  manner. In
general,  Section 203 defines an interested  stockholder as any entity or person
beneficially  owning  15%  or  more  of  the  outstanding  voting  stock  of the
corporation  and  any  entity  or  person  affiliated  with  or  controlling  or
controlled by this type of entity or person.  The possible issuance of preferred
stock and the  provisions of Delaware law could have the effect of  discouraging
others from making tender offers for our securities. As a consequence, they also
may inhibit  fluctuations in the market price of our common stock that otherwise
could result from actual or rumored takeover attempts. Those provisions also may
have the effect of preventing changes in our management.

ITEM 6.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                  AND PLAN OF OPERATIONS

The following discussion reflects the historical results of Old Discovery as the
1997 Merger was accounted for as a reverse acquisition with Old Discovery as the
acquiror for financial reporting purposes.

Plan of Operations

Since its inception,  the Company has  concentrated its efforts and resources on
the   development  and   commercialization   of   pharmaceutical   products  and
technologies.  The  Company has been  unprofitable  since its  founding  and had
incurred a cumulative net loss of approximately $32.4 million as of December 31,
1999. The Company expects to incur  significantly  increasing  operating  losses
over the next several years,  primarily due to the expansion of its research and
development programs,  including clinical trials for some or all of its existing
products  and  technologies  and other  products  and  technologies  that it may
acquire or develop. The Company's ability to achieve profitability depends upon,
among  other  things,  its  ability to discover  and  develop  products,  obtain
regulatory  approval for its proposed  products,  and enter into  agreements for
product development, manufacturing and commercialization.  None of the Company's
products currently generates revenues and the Company does not expect to achieve


                                       24
<PAGE>


revenues for the foreseeable  future.  Moreover,  there can be no assurance that
the Company will ever achieve significant revenues or profitable operations from
the sale of any of its products or technologies.

The Company is currently  engaged in the  development and  commercialization  of
drugs for critical care that are intended to be used in a hospital setting.  The
Company  anticipates that during the next 12 months it will conduct  substantial
research and  development  of its products  under  development  and that it will
focus primarily on the conduct of clinical  trials for Surfaxin(R)  indications.
The Company  expects to expand its  research  and  development  activities  as a
result of its receipt of  approximately  $17.5  million of net proceeds from its
offering  completed  in March  2000.  The  Company  anticipates  the  near  term
acquisition of equipment necessary to manufacture Surfaxin(R).  The Company also
anticipates the hiring of further personnel to augment the clinical  development
of  Surfaxin(R).  A pivotal  Phase 2/3  clinical  trial of  Surfaxin(R)  for the
treatment of ARDS/ALI was commenced on July 14, 1998. This trial was intended to
enroll  approximately  540 patients and be conducted at up to 43 clinical  sites
nationwide. This trial was stopped on January 27, 2000 due to the Company's cash
position  and so that a new Phase 2 ARDS/ALI  trial could be  commenced  using a
new, less viscous  formulation of Surfaxin(R).  A new Phase 2 trial is currently
being planned,  which we expect to commence  following  submission of a protocol
and subsequent approval by the FDA.

A Phase 2A clinical trial of Surfaxin(R)  for the treatment of MAS was commenced
on May 27, 1997. This trial was completed and results were announced on February
4, 1999.  The Company  initiated a pivotal Phase 3 trial in MAS in January 2000.
The trial  intends  to enroll  200 MAS  patients.  The  Company  is  engaged  in
discussions  with the FDA concerning a protocol for Phase 3 clinical  trials for
Surfaxin(R)  for RDS. The Company intends to commence the Phase 3 clinical trial
upon approval of the protocol on terms  acceptable  to the Company.  Such trial,
and any other clinical trials of the Company's products in development that have
not yet  commenced,  will require the receipt of approvals by the United  States
Food and Drug  Administration  (the "FDA").  There can be no assurance as to the
receipt or the timing of such approvals.

A Phase 1/2 clinical trial of SuperVent(TM) for the treatment of cystic fibrosis
("CF")  was  commenced  on March 17,  1997.  Part A of such  clinical  trial was
completed  on March 31,  1998.  The Company  began a Phase 2a clinical  trial of
SuperVent(TM) for the treatment of CF on August 4, 1999. Preliminary analysis of
the data show that SuperVent(TM) decreased the amount of Interleukin 8 (IL-8) in
the sputum of treated patients  compared to controls.  IL-8 is an important body
chemical that causes the migration of inflammatory cells to the site of release.

On  December  5, 1997 a Phase 1  clinical  study of DSC-103  (formerly  known as
ST-630)  as  a  once-daily,  orally  administered  drug  for  the  treatment  of
postmenopausal  osteoporosis in the United States was initiated.  Part B of such
trial was commenced on April 2, 1998 and was successfully  completed on June 29,
1998. It is the Company's present intention to seek to develop DSC-103 through a
corporate partnering arrangement rather than directly.

The Company's expenses decreased from $16,090,000 in 1998 to $5,292,000 in 1999.
The decrease resulted primarily from a write-off of acquired in-process research
and  development and supplies in 1998. In addition,  the Company's  research and
development  costs decreased from $5,082,000 in 1998 to $2,869,000 in 1999. This
decrease resulted  primarily from a slow-down in research and development due to
the  Company's  cash  position.  As a result of the receipt of proceeds from the
private placement completed in March, 2000, the Company expects to significantly
increase its research and development and clinical trial efforts. As a result of
the


                                       25
<PAGE>

decreases in expenses from 1998,  the  Company's  total  comprehensive  net loss
decreased from  $15,626,000  in 1998 to $4,958,000 in 1999. In addition,  due to
the  reduction  in the  total  comprehensive  net loss and the  increase  in the
weighted average common shares  outstanding  during 1999, the Company's net loss
per share decreased from $4.02 in 1998 to $0.66 in 1999.

Liquidity

At December 31, 1999, the Company had working capital of $2.7 million.  In March
2000, the Company  completed a private  placement  pursuant to which it received
net proceeds of  approximately  $17.5 million.  The Company believes its working
capital  after  completion  of the  offering is  sufficient  to meet its planned
research and development activities through the third quarter 2001. However, the
Company  will need  additional  financing  from  investors or  collaborators  to
complete research and development of its product candidates.

The  Company's  working  capital has been  provided from the proceeds of private
financings. On April 7, 1999 (the "April 1999 Financing"), the Company completed
a private  placement  of shares of  Common  Stock and a newly  created  class of
warrants of the Company (the "Class C Warrants") for an aggregate purchase price
of $1,000,000. Investors in the April 1999 Financing received, in the aggregate,
826,447  shares  of  Common  Stock at an  adjusted  purchase  price of $1.21 and
569,026  Class C Warrants,  each of which is  exercisable  for the purchase of a
share of Common  Stock for an  exercise  price of $2.15 at any time prior to the
seventh anniversary of the issuance of such warrant.

On July 29, 1999,  the Company  received $2.45 million in gross proceeds when it
completed a private offering of Units (the "Unit Offering"), at a per Unit price
of $500,000, consisting of (a) 413,223 shares of the Company's Common Stock, par
value  $0.001  per share  (the  "Common  Stock,  and (b) an equal  number of the
Company's  Class D  Warrants,  each of which  entitles  the  holder  thereof  to
purchase a share of Common  Stock at any time prior to the close of  business on
July 27, 2004 at a per share purchase price equal to $1.33.  Paramount  Capital,
Inc.  received options (the "Placement  Options") to acquire 0.49 Units at a per
Unit  exercise  price of $550,000 as partial  compensation  for its  services in
connection with the Unit Offering.

Pursuant to an agreement  entered into on October 28, 1999,  the Company  issued
317,164 shares of Common Stock to Laboratorios  P.E.N., S.A. at a price of $2.68
per share (based on a 50% premium over the average closing price for the 10 days
prior to the closing  date) for  aggregate  proceeds of $850,000.  The shares of
Common Stock were issued to  Laboratorios  P.E.N.,  S.A. in connection  with the
Sublicense  Agreement with Laboratorios Del Dr. Esteve, S.A.  ("Laboratorios Dr.
Esteve") described under "Item 1. Description of Business".

On March 22,  2000,  the Company  received  approximately  $17.5  million in net
proceeds in a private offering of Units at a per unit price of $500,000. Each of
the Units consisted of (a) 76,923 shares of the Company's common stock and (b) a
number of Class E warrants  equal to 20% of the number of shares of common stock
included in each Unit,  each of which  entitles the holder to purchase one share
of common  stock at any time prior to the close of business on March 21, 2005 at
an exercise  price per share equal to $7.63 per share.  In  addition,  Paramount
received cash fees of  approximately  $1.32 million and options (the  "Placement
Options")  to acquire  9,230 shares of common stock per Unit sold at an exercise
price of $8.113 per share as partial compensation for its services in connection
with the offering.

The Company's  working capital  requirements  will depend upon numerous factors,
including,   without   limitation,   progress  of  the  Company's  research  and
development  programs,  preclinical  and  clinical  testing,  timing and cost of
obtaining regulatory approvals,  levels of resources that the


                                       26

Company devotes to the development of manufacturing and marketing  capabilities,
technological advances,  status of competitors and the ability of the Company to
establish collaborative arrangements with other organizations.

INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
Discovery Laboratories, Inc.
Doylestown, Pennsylvania


We have  audited  the  accompanying  consolidated  balance  sheet  of  Discovery
Laboratories,  Inc. and subsidiary (a development  stage company) as of December
31, 1999,  and the related  consolidated  statements of  operations,  changes in
stockholders' equity and cash flows for each of the years in the two-year period
ended  December 31, 1999, and the period from May 18, 1993  (inception)  through
December 31, 1999.  These  financial  statements are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements enumerated above present fairly, in all
material   respects,   the   consolidated   financial   position  of   Discovery
Laboratories,  Inc. and subsidiary as of December 31, 1999 and the  consolidated
results of their  operations and their  consolidated  cash flows for each of the
years in the two-year  period ended  December 31, 1999,  and the period from May
18, 1993  (inception)  through  December 31, 1999, in conformity  with generally
accepted accounting principles.

DISCOVERY LABORATORIES, INC. AND SUBSIDIARY
(a development stage company)

Notes to Financial Statements

NOTE A - THE COMPANY AND BASIS OF PRESENTATION

Discovery   Laboratories,   Inc.  (the  "Company"),   formerly  known  as  Ansan
Pharmaceuticals,  Inc.  ("Ansan"),  was  incorporated in Delaware on November 6,
1992 and was formed to license  and develop  pharmaceutical  products to treat a
variety of human diseases.  In November 1997,  Ansan merged (the "Ansan Merger")
with  Discovery   Laboratories,   Inc.,  a  former  Delaware  corporation  ("Old
Discovery"),  and was the surviving  corporate  entity.  Subsequent to the Ansan
Merger, Ansan changed its name to Discovery Laboratories,  Inc. The Ansan Merger
was  accounted for as a reverse  acquisition  with Old Discovery as the acquirer
for  financial  reporting  purposes  since Old  Discovery's  stockholders  owned
approximately  92% of the merged  entity on a diluted  basis.  The  consolidated
financial  statements  include the accounts of Ansan from November 25, 1997 (the
date of acquisition).

Acute  Therapeutics,  Inc.  ("Old  ATI")  was  formed in  October  1996 upon the
Company's  investment of $7,500,000 in exchange for 600,000  shares of Old ATI's
Series A preferred stock,  then representing 75% of the voting securities of Old
ATI. In June 1998,  ATI  Acquisition  Corp.,  a wholly owned  subsidiary  of the
Company  merged  with and into Old ATI with Old ATI being the  surviving  entity
(the "Old ATI Merger").  Pursuant to the Old ATI Merger,  each outstanding share
of Old ATI's common stock was exchanged for 3.90 shares of the Company's  common
stock (the "Old ATI Exchange Ratio"), each share of Old ATI's Series B preferred
stock was converted into one share of the Company's Series C preferred stock and
all  outstanding  options to purchase  Old ATI common  stock were assumed by the
Company and are  exercisable  for shares of the  Company's  common  stock on the
basis of the Old ATI Exchange Ratio.  Further, in accordance with the employment
agreements  entered into with the Company in connection with the Old ATI Merger,
Old ATI  management  was  granted,  in the  aggregate,  options to purchase  (i)
338,500  shares of the  Company's  common  stock,  subject to  vesting  and (ii)
335,000  shares of the  Company's  common stock  subject to the  achievement  of
certain corporate milestones.  At December 31, 1999, the milestones had not been
achieved  and thereby the options for the 335,000  shares  remain  unvested.  As
these options vest, the Company will incur a charge at each vesting date for the
excess,  if any of the  market  price of the  Company's  common  stock  over the
exercise price of the options. In addition,  pursuant to a management  agreement
entered  into  between the Company and Old ATI at the time the merger  agreement
relating to the Old ATI Merger was executed,  the members of Old ATI  management
were granted options to purchase 126,500 shares of the Company's common stock.

In October 1999, Old ATI was merged with and into the Company.  In October 1999,
the Company created a new wholly owned subsidiary,  which is currently inactive,
called Acute Therapeutics, Inc. ("New ATI").

The  historical  consolidated  financial  position of the Company  includes  the
accounts of Old ATI. The value of the common stock of the Company  issued to Old
ATI's common stockholders plus the assumption of the outstanding Old ATI options
and  merger  related  costs  has been  attributed  to  in-process  research  and
development  upon  management's  evaluation  and has been recorded as an expense
upon acquisition.

The cost of the Old ATI Merger is as follows:

As reflected in the accompanying  financial  statements,  since  inception,  the
Company has  incurred  substantial  losses from  operations.  As a result of the
start-up  nature of its business,  the Company can expect to continue  incurring
substantial operating losses for at least the next several years and significant
additional  financing will be required.  On March 23, 2000, the Company received
$17,500,000  net proceeds  from the sale of 37.74 units in a private  placement.
Each unit  consists  of 76,923  shares of common  stock and Class E warrants  to
purchase an  additional  15,385  shares of common  stock at $7.38 per share.  In
connection with this private placement,  the placement agent, Paramount Capital,
Inc.  ("Paramount")  received fees of $1,321,000 and the Company agreed to issue
to Paramount  warrants to purchase  348,341 shares of common stock at $8.113 per
share.  Continuation  of the  Company  is  dependent  on its  ability  to obtain
additional  financing  and,  ultimately,  on its  ability to achieve  profitable
operations.  There  is no  assurance,  however,  that  such  financing  will  be
available or that the Company's efforts will ultimately be successful.


NOTE B - RETROACTIVE ADJUSTMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS

In October  1996,  in  conjunction  with a licensing  agreement  with  Johnson &
Johnson,  Inc.'s ("J&J") wholly owned subsidiary,  Ortho  Pharmaceuticals,  Inc.
(see Note  F[1]),  J&J  contributed  manufacturing  equipment  and raw  material
inventory  in exchange for the  Company's  non-voting  Series B preferred  stock
which had a liquidation  preference of  $2,039,000.  The equipment and inventory
was charged to operations as acquired  in-process  research and  development and
supplies during the year ended December 31, 1996.  However,  certain of this raw
material inventory,  valued at approximately $575,000, which was then located at
the vendor,  had an alternative  future use. Such inventory could have been sold
to other  users and was in excess of the  estimated  quantity  required  for the
Company's research and development  purposes.  The Company had arranged with the
vendor to defer delivery of the product.  Previously issued financial statements
have been restated to reflect capitalizing such inventory effective December 31,
1996 and a corresponding reduction in deficit accumulated during the development
stage.

NOTE C - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

[1] Cash and cash equivalents:

       The Company  considers all highly  liquid  investments  purchased  with a
       maturity of three months or less to be cash equivalents.

[2] Marketable securities:

       The  investments  are classified as available for sale, and are comprised
       of United States government obligations and shares in a mutual fund which
       invests in income producing  securities.  Investments are carried at fair
       or market value. Any  appreciation/depreciation  on these  investments is
       recorded as a separate component of stockholders' equity until realized.

[3] Property and equipment:

       Furniture  and  equipment is recorded at cost.  Depreciation  is computed
       using the  straight-line  method over the  estimated  useful lives of the
       assets (five to seven years).  Leasehold  improvements are amortized over
       the  lower  of  (a)  term  of  the  lease  or  (b)  useful  life  of  the
       improvements.

[4] Inventory:

       Inventory  is stated at the lower of cost or market and  consists  of raw
       materials.

[5] Licenses:

       Through March 1997, licenses were capitalized and were being amortized on
       a  straight-line  basis  over their  respective  terms of 15 to 17 years.
       Subsequently,  the Company determined that since they will not pursue any
       alternative  uses for the  licenses,  that  all  license  costs  would be
       written off as research and development costs.

[6] Research and development:

       Research and  development  costs are charged to  operations  as incurred.
       Certain of the Company's research and development efforts are funded by a
       grant  awarded to the Company by the Food and Drug  Administration.  Draw
       downs of the grant are included in research  grant  revenue.  In 1999 and
       1998,  the  amounts  funded  were  approximately   $71,000  and  $27,000,
       respectively.

[7] Use of estimates:

       The  preparation  of financial  statements in conformity  with  generally
       accepted accounting  principles requires management to make estimates and
       assumptions that affect the reported amounts of assets and liabilities at
       the date of the financial statements and the reported amounts of revenues
       and expenses  during the reporting  period.  Actual  results could differ
       from those estimates.

[8] Long-lived assets:

       In accordance with Statement of Financial  Accounting  Standards No. 121,
       "Accounting  for the  Impairment of Long-Lived  Assets and for Long-Lived
       Assets to be  Disposed  of," the  Company  records  impairment  losses on
       long-lived assets used in operations,  including  intangible assets, when
       events and  circumstances  indicate that the assets might be impaired and
       the undiscounted cash flows estimated to be generated by those assets are
       less than the carrying amounts of those assets.  No such losses have been
       recorded.


                                                                            F-10

NOTE C - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  (CONTINUED)

[9] Stock-based compensation:

       The Company adopted Statement of Financial  Accounting Standards No. 123,
       "Accounting  for  Stock-Based   Compensation"   ("SFAS  No.  123").   The
       provisions  of SFAS  No.  123  allow  companies  to  either  expense  the
       estimated  fair value of employee  stock options or to continue to follow
       the  intrinsic  value  method set forth in  Accounting  Principles  Board
       Opinion 25,  "Accounting  for Stock Issued to  Employees"  ("APB 25") but
       disclose the pro forma effects on net income (loss) had the fair value of
       the options been  expensed.  The Company has elected to continue to apply
       APB 25 in accounting for its employee stock option  incentive  plans. See
       Note H to the financial statements for further information.

[10]  Net loss per share:

       Net loss per share is computed pursuant to the provisions of Statement of
       Financial  Accounting Standards No. 128 "Earnings per Share" and is based
       on the  weighted  average  number of common  shares  outstanding  for the
       periods and common shares  issuable for little or no cash  consideration.
       Potential  common shares not included in the  calculation of net loss per
       share for the years ended December 31, 1999 and 1998, as the effect would
       be anti-dilutive, are as follows (Notes G and H):

  Class D warrants                                     2,025,000


[11]  Comprehensive income:

       During  1998,  the Company  adopted  Statement  of  Financial  Accounting
       Standards No. 130 "Reporting  Comprehensive  Income",  which  establishes
       standards  for  reporting  and  display of  comprehensive  income and its
       components.   Accordingly,   the  Company   revised  the  format  of  its
       consolidated  statements of  operations  to include  total  comprehensive
       income.  The adoption of this  statement  had no effect on the  Company's
       results of operations.

[12]  Reclassifications:

       Certain prior year amounts have been  reclassified to conform to the 1999
       presentation.

NOTE D - PROPERTY AND EQUIPMENT

At December 31, 1999 property and equipment was comprised of the following:

           Leasehold improvements                 $ 92,000
           Furniture                                53,000

                                                 $ 426,000
                                               ===========

Equipment includes property under a capitalized lease of $73,000 and accumulated
depreciation of $3,000.

During 1998 and 1999, the Company paid an aggregate $107,000 to the spouse of an
officer for the acquisition of leasehold improvements.


NOTE E - INCOME TAXES

At December 31, 1999,  the Company has available for federal income tax purposes
net operating loss carryforwards of approximately  $28,000,000  expiring through
2019,  that may be used to  offset  future  taxable  income.  As a result of the
ownership change pursuant to the Ansan Merger, use of Ansan's portion of the net
operating loss  carryforward  of  approximately  $9,500,000 at November 1997, is
limited in accordance with Section 382 of the Internal Revenue Code. Pursuant to
Section 382 of the Internal Revenue Code, the utilization of these carryforwards
may become  further  limited  based on certain  ownership  changes that may have
occurred  or  may  occur.  The  Company  has  research  and  development  credit
carryforwards of approximately $671,000 which expire in 2019. Ansan's portion of
these  credits of  approximately  $179,000  are also  subject  to a Section  383
limitation.  There will be an annual amount  available to offset future  taxable
income.

The principal  difference between the deficit accumulated during the development
stage for financial  reporting  purposes and the net operating loss carryforward
for tax purposes is primarily  due to the  write-off of the acquired  in-process
research  and  development  and supplies  and certain  research and  development
expenses  which were not deducted for tax  purposes.  The Company has provided a
valuation  reserve  against  the  full  amount  of the  deferred  tax  asset  of
$11,267,000 since realization of this benefit is not certain.  The components of
the deferred tax assets are net operating loss  carryforwards  of  approximately
$10,246,000,  research and development  expenses of  approximately  $350,000 and
research  and  development  credits of  approximately  $671,000.  The  valuation
reserve increased by approximately $1,989,000 and $1,924,000 for the years ended
December 31, 1999 and 1998,  respectively.  The difference between the statutory
federal income tax rate of 34% and the Company's effective tax rate of 0% is due
to the increase in the valuation allowance.


NOTE F - LICENSE, SUBLICENSE AND RESEARCH FUNDING AGREEMENTS

[1]    Concurrent with the Company's original investment in Old ATI, Johnson
       & Johnson,  Inc.  ("J&J "), Ortho  Pharmaceuticals,  Inc., a wholly owned
       subsidiary  of J&J,  and Old ATI  entered  into an  agreement  (the  "J&J
       License  Agreement")  granting an  exclusive  license of the  Surfaxin(R)
       technology to Old ATI in exchange for certain  license fees  ($200,000 of
       which  was  paid  in  November  1996),   milestone  payments  aggregating
       $2,750,000,  royalties  and 40,000  shares of Old ATI common  stock.  J&J
       contributed  its  Surfaxin(R)  raw material  inventory and  manufacturing
       equipment to Old ATI in exchange for 2,039  (originally  2,200) shares of
       nonvoting  Series  B  preferred  stock  of Old ATI  having  a  $2,039,000
       (originally  $2,200,000)  liquidation  preference  and a $100  per  share
       cumulative annual dividend. The inventory and equipment were valued at

       $2,039,000  (the value of the  preferred  shares  issued to J&J) and were
       charged to expense in full (see Note B). The Scripps  Research  Institute
       ("Scripps") received 40,000 shares of common stock of Old ATI in exchange
       for its consent to the J&J License Agreement.

[2]    In  October  1999,  the  Company  granted  an  exclusive  license  to
       Laboratorios  Del Dr. Esteve S.A. to  commercialize  and sell Surfaxin(R)
       within Central and South America,  Mexico and certain  Southern  European
       countries,  not including  Italy.  The license  expires,  on a country by
       country basis,  on the later of the expiration of the underlying  patents
       or  the  fifteenth   anniversary   from  the  first  commercial  sale  of
       Surfaxin(R)  within  each  country.   Certain  additional  terms  of  the
       agreement are:

       (a) the Company was paid a nonrefundable license fee of $375,000,

       (b) the Company will be the exclusive supplier (except in certain events)
           of Surfaxin(R),

       (c)  Laboratorios  Del Dr. Esteve S.A. agreed to conduct certain clinical
            trials  in  the  above  countries,  however,  costs  as  defined  in
            the agreement,  incurred on such clinical trials above an agreed
            upon amount, will be borne by the Company,

       (d)  Laboratorios  Del Dr.  Esteve  S.A.  paid  $375,000  in advance  for
            Surfaxin(R)supplied for clinical trials described in (c) above,

       (e) an affiliate of Laboratorios Del Dr. Esteve S.A. invested $850,000 in
           the Company in exchange for common stock issued at a 50% premium over
           the ten day average closing price preceding the closing of this
           transaction. The Company has  accounted  for the premium as
           additional  license  fees amounting to $286,000, and

       (f) an option to an exclusive license for Italy for additional  specified
           payments.

       The Company has  accounted  for the license fees  (including  the premium
       paid for common  stock) and  advance  payment for  inventory  as deferred
       revenue.  Such  deferred  revenue will be  recognized as revenue as it is
       earned.

[3]    In 1996, Old ATI entered into a research funding and option agreement
       with  Scripps to provide  certain  funding of  research  activities.  The
       agreement  was for an initial term of two years with  renewal  provisions
       for additional one year periods. On March 1, 2000 the Company and Scripps
       entered into an agreement to extend the term for one year and provide for
       additional  one year renewal  options.  Pursuant to this  agreement,  the
       Company  will pay $248,000  per year  Scripps to fund  Scripps'  research
       efforts.  The  agreement  provides  for Scripps to grant an option to the
       Company to acquire an exclusive license for the application of technology
       developed from the research program. Pursuant to the agreement,  payments
       to Scripps were $115,000 and $460,000 in 1999 and 1998, respectively.

[4]    In 1996,  the  Company  entered  into a  license  agreement  with the
       Charlotte-Mecklenburg  Hospital  Authority  for  the  use of  the  active
       compound in SuperVent, a therapy which the Company is clinically testing.
       The  Company  paid a license  issue fee of $86,000  and has agreed to pay
       royalties on future  sales and to pay future  patent-related  costs.  The
       license expires upon expiration of the underlying patents.


                                                                            F-13

[5]    In 1996,  the  Company  entered  into a  license  agreement  with the
       Wisconsin Alumni Research Foundation ("WARF") for the use of the patented
       compound DSC 103 (formerly  ST-630) in the  treatment of  post-menopausal
       osteoporosis. The Company paid WARF an option fee of $25,000 in June 1996
       and a license  issue fee of $400,000 in October  1996 and is obligated to
       make future milestones payments aggregating  $3,095,000 and pay royalties
       on future sales.  The license  expires upon  expiration of the underlying
       patents.  The Company is  currently  seeking a  development  partner with
       respect to this compound.

       In June 1999, the Company  granted YuYu Industrial  Company,  Ltd. ("YuYu
       Industrial") of South Korea an exclusive license to use the DSC 103 and a
       nonexclusive  license to manufacture the compound and ancillary compounds
       in South Korea. Under the agreement,  YuYu Industrial paid the Company an
       up-front payment of $68,000 including  research and development fees, net
       of  $12,000  withheld  for  South  Korean  taxes,  and  agreed  to make a
       subsequent  milestone payment of $50,000.  YuYu Industrial also agreed to
       purchase  specified minimum quantities of the drug compound for the first
       five years  following  the receipt of  approval  for  marketing  licensed
       products  within South Korea.  The Company is entitled to receive royalty
       payments for all product sales under the agreement.

NOTE G - STOCKHOLDERS' EQUITY

1996 private placement:

In 1996, in a private placement  offering,  Old Discovery sold  approximately 44
units (each unit  consisting  of  securities  converted in the Ansan Merger into
50,000  shares of Series B  convertible  preferred  stock and  19,458  shares of
common stock of the Company).  Preferred  stockholders  have voting rights based
upon the  number of  shares of common  stock  issuable  upon  conversion  of the
preferred  shares.  Pursuant to the terms of the offering,  on December 1, 1998,
the  conversion  rate was  adjusted  whereby  each share of  preferred  stock is
convertible at the option of the holders into 3.11 shares of common stock of the
Company. Net proceeds from the private placement approximated  $19,000,000.  The
Company is restricted from declaring  dividends or  distributions  on its common
stock without the approval of the holders of at least 66.67% of the  outstanding
Series B  shares  as long as there is in  excess  of  1,100,000  Series B shares
outstanding.

In February 2000, the Company gave notice to its Series B convertible  preferred
stockholders  of its  intention  to convert all  outstanding  shares of Series B
preferred stock into common stock.  Pursuant to the notice,  all of the Series B
shares were converted into 4,766,000  shares of common stock effective March 14,
2000.

The placement agent for the offering received  approximately  $2,860,000 in cash
plus warrants which pursuant to the merger give the holders thereof the right to
acquire  220,026  shares of Series B preferred  stock  (which as a result of the
conversion of the Series B preferred stock are  convertible  into 685,000 shares
of common  stock) at a price of $11 per share,  through  November 8, 2006 and to
acquire  85,625  shares of common  stock at a price of $0.64 per share,  through
November 8, 2006. The warrants contain certain anti-dilution  provisions and may
be exercised on a "net  exercise"  basis  pursuant to a provision  that does not
require the payment of any cash to the Company.

1999 private placements:

During  March  and April  1999 the  Company  raised  $1.0  million  in a private
placement  offering  of  826,447  shares of common  stock  and  569,026  Class C
warrants to purchase common stock at an exercise price of $2.15 per share (after
adjustment to the issue price in accordance with the terms of the offering). The
Class C warrants are exercisable through April 2006.


                                                                            F-14

1999 private placements:  (continued)

In July 1999, the Company raised approximately $2,233,000 (net of offering costs
of approximately  $217,000) in a private placement  offering of units. Each unit
was sold for  $500,000  and  consisted  of  413,223  shares of common  stock and
413,223 Class D warrants to purchase shares of common stock at an exercise price
of $1.33 per  share.  An  aggregate  of  2,024,792  shares  of common  stock and
2,024,792 Class D warrants were issued. The placement agent,  Paramount Capital,
Inc.,  received  fees at 7% of the  gross  proceeds,  reimbursement  of  certain
expenses and an option to purchase 0.49 share of a unit at an exercise  price of
$270,000. The Class D warrants are exercisable through August 2005.

Unit offering:

In August 1995,  Ansan issued an aggregate of 498,333  units  (including  65,000
units pursuant to the underwriter's  overallotment option) at $15.00 per unit in
an initial public offering (the "Offering"). Each unit consisted of one share of
common stock,  one  redeemable  Class A warrant,  and one Class B warrant.  Each
Class A warrant  entitles  the holder to purchase  one share of common stock and
one Class B warrant  at an  exercise  price of $19.50  per  share.  Each Class B
warrant  entitles  the holder to purchase  one share of common stock an exercise
price of $26.25 per share.

In  connection  with the Offering,  the holders of the Ansan's  common stock and
options to purchase  common stock placed,  on a pro rata basis,  121,246  shares
(including 115,491 shares held by the Company pending  cancellation  pursuant to
the Ansan Merger (Note A)) and options to purchase 12,086 shares of common stock
into escrow (the "Escrow Shares" and "Escrow Options", respectively). The Escrow
Shares and Escrow  Options are not  transferable  or  assignable;  however,  the
Escrow Shares may be voted. Holders of Escrow Options may exercise their options
prior to their release from escrow;  however,  the shares issuable upon any such
exercise  will  continue  to be held in  escrow.  The  Escrow  Shares and Escrow
Options will be released from escrow if, and only if, certain earnings or market
price  criteria have been met. If the  conditions are not met by March 31, 2000,
the Escrow Shares and Escrow  Options will be cancelled and  contributed  to the
Company's capital.

The release of Escrow  Shares and Escrow  Options held by  employees,  officers,
directors,   consultants  and  their  relatives  will  be  deemed  compensatory.
Accordingly,  the Company will  recognize as  compensation  expense,  during the
period in which the earnings or market price targets are met, a one-time  charge
to reflect the then fair market value of the shares  released from escrow.  Such
charges could substantially  reduce the Company's net income or increase the net
loss.  The amount of  compensation  expense  recognized  by the Company will not
affect the total stockholders' equity.

Common shares reserved for issuance:

As of December 31, 1999, the Company has reserved shares of common stock for
issuance upon conversion of preferred stock and exercise of options as follows:

           (i)     Series B preferred stock            4,766,000
           (ii)    Series C preferred stock              892,000

NOTE G - STOCKHOLDERS' EQUITY  (CONTINUED)

Treasury stock/common stock issued for services:

During  1998,  the  Company's  Board of  Directors  approved a stock  repurchase
program  wherein the  Company  would buy its own shares from the open market and
use such  shares  to settle  indebtedness.  Such  shares  are  accounted  for as
treasury stock.

During 1999 and 1998,  the Company  acquired  2,000 and 31,750  shares of common
stock for approximately $5,000 and $90,000,  respectively.  In 1998, the Company
issued  16,150  of such  shares  (market  value  on date of  issue  $51,000)  in
settlement  of $51,000 of services  rendered and in 1999 issued 15,600 shares of
treasury stock in settlement of $39,000 of  indebtedness.  The fair market value
of the  15,600  shares of  treasury  stock on the date it was issued in 1999 was
approximately  $53,000 and the difference was charged to expense and credited to
paid-in-capital.

Series C preferred stock:

The Company's Series C redeemable  convertible preferred stock is convertible at
the option of the holder into common  stock at a  conversion  price equal to the
market price of the common  stock,  as defined.  Such shares are  redeemable  at
liquidation  value upon the occurrence of certain events.  The liquidation value
is  payable  at the  option of the  Company  in either  cash or shares of common
stock.  Series C  stockholders  are entitled to dividends of 10% per annum to be
paid only upon liquidation or redemption.

On March 3, 2000,  J&J elected to convert their Series C preferred  stock shares
into 398,186 shares of common stock.


NOTE H - STOCK OPTIONS

Ansan's 1993 Stock Option Plan which was amended and restated (the "1993 Plan"),
provided  that  incentive  stock  options  may  be  granted  to  employees,  and
nonstatutory stock options may be granted to employees,  directors,  consultants
and affiliates. In May 1995, Ansan adopted the 1995 Stock Option Plan (the "1995
Plan"). No further options will be granted under the 1993 Plan or 1995 Plan.

Options granted under the 1993 Plan and 1995 Plan expire no later than ten years
from the date of grant,  except  when the  grantee is a 10%  stockholder  of the
Company or an  affiliate  company,  in which case the maximum term is five years
from the date of grant.  The exercise price shall be at least 100%, 85% and 110%
of the fair  value of the stock  subject  to the  option on the grant  date,  as
determined by the Board of Directors, for incentive stock options,  nonstatutory
stock  options  and  options  granted  to 10%  stockholders  of the  Company  or
affiliate  company,  respectively.  Options  granted  under  the  1993  Plan are
exercisable  immediately upon grant,  however, the shares issuable upon exercise
of the options are subject to repurchase by the Company.  Such repurchase rights
lapse as the shares vest over a period of five years from the date of grant.

On  consummation  of the Ansan  Merger,  the  Company  assumed  Old  Discovery's
outstanding options which were exchanged at the Ansan Exchange Ratio for options
to purchase the Company's common stock (Note A).

In March 1998, the Company  adopted its 1998 Stock Incentive Plan which includes
three equity programs (the "1998 Plan").  Under the  Discretionary  Option Grant
Program,  options to acquire shares of the Company's common stock may be granted
to eligible persons who are employees,  nonemployee  directors,  consultants and
other  independent  advisors.  Pursuant  to the  Stock  Issuance  Program,  such
eligible  persons may be issued shares of the Company's  common stock  directly,
and  under  the  Automatic  Option  Grant  Program,   eligible   directors  will
automatically  receive option grants at periodic  intervals at an exercise price
equal to 60% of fair  market  value  per  share on the  date of the  grant.  The
maximum  number of shares of common stock  initially  reserved for issuance over
the term of the plan shall not exceed 2,200,959.


                                                                            F-16

NOTE H - STOCK OPTIONS  (CONTINUED)

The pro forma effects of applying  SFAS No. 123 and the stock  options  activity
shown below are those of the 1998 Plan, Old Discovery's 1996 Stock  Option/Stock
Issuance  Plan  through the date of the Ansan  Merger and the 1993 Plan and 1995
Plan after the Ansan Merger as the Ansan Merger was  accounted  for as a reverse
acquisition.

The Company  applies APB 25 in accounting  for stock  options and,  accordingly,
recognizes compensation expense for the difference between the fair value of the
underlying  common  stock and the  exercise  price of the  option at the date of
grant.  The  effect  of  applying  SFAS  No.  123 on pro  forma  net loss is not
necessarily  representative  of the effects on  reported  net income or loss for
future years due to,  among other  things,  (i) the vesting  period of the stock
options and (ii) the fair value of additional stock options in future years. Had
compensation  cost for the Company's  stock option plans been  determined  based
upon the fair value of the  options at the grant date of awards  under the plans
consistent with the methodology prescribed under SFAS No. 123, the Company's net
loss for each of the years  ended  December  31,  1999 and 1998  would have been
approximately  $5,622,000 or $0.74 per share and $16,371,000 or $4.20 per share,
respectively.  The  weighted  average  fair  value of the  options  granted  are
estimated  at $2.46 and  $2.63  per  share,  respectively,  for the years  ended
December  31,  1999  and  1998,  on the date of grant  using  the  Black-Scholes
option-pricing model with the following weighted average  assumptions:  dividend
yield 0%, volatility of 91% and 40%,  risk-free  interest rate of 4.86% for 1999
and 5.53% for 1998, and expected life of ten years.

Additional  information  with respect to the stock option activity is summarized
as follows:

Included in the options outstanding at December 31, 1999 are options to purchase
912,893 shares of the Company's common stock (at exercise prices ranging from
$1.38 to $4.44) granted during 1998 and 1999 which vest upon the Company
achieving specified milestones. Through December 31, 1999, the milestones were
not reached and the options remain unvested. On vesting, the Company will incur
a charge amounting to the excess, if any, of the market price over the exercise
price.


NOTE I - COMMITMENTS

[1]   At December 31, 1999, the Company had employment agreements with six
      officers providing for an aggregate annual salary of $853,000. The
      agreements expire on various dates through June 2002 and provide for the
      issuance of annual and milestone bonuses and the granting of options on
      the Company's attaining certain milestones.

         series, and determine or change the designation, relative rights,
         preferences, and limitations of any series of Preferred Stock. The
         board of Directors (within the limits and restrictions of any
         resolutions adopted by it originally fixing the number of any shares of
         any series of Preferred Stock) may increase or decrease the number of
         shares initially fixed for any series, but no such decrease shall
         reduce the number below the number of shares then outstanding and
         shares duly reserved for issuance.

         1. Exercise of Option.
            ------------------

         (a) This Option may be exercised,  in whole at any time or in part from
time to time,  commencing on December 28, 1999 and prior to 5:00 P.M.,  New York
City time, on December 28, 2004 by the Holder:

          (i) by the surrender of this Option (with the subscription form at the
     end hereof  duly  executed)  at the address  set forth in  Subsection  9(a)
     hereof,  together with proper payment of the Aggregate Option Price, or the
     proportionate  part  thereof  if this  Option is  exercised  in part,  with
     payment for the number of Units made by  certified  or official  bank check
     payable to the order of the Company; or

          (ii) by the surrender of this Option (with the cashless  exercise form
     at the end hereof duly executed) (a "Cashless Exercise") at the address set
     forth in  Subsection  9(a)  hereof.  The  exchange of the Option shall take
     place on the date specified in the Cashless Exercise Form or, if later, the
     date  the  Cashless  Exercise  Form  is  surrendered  to the  Company  (the
     "Exchange Date").  Such presentation and surrender shall be deemed a waiver
     of the  Holder's  obligation  to pay the  Aggregate  Option  Price,  or the
     proportionate  part  thereof if this Option is  exercised  in part.  In the
     event of a Cashless  Exercise  this  Option  shall  represent  the right to
     subscribe for and acquire the number of Units  (rounded to the next highest
     integer)  equal to (x) the  number  of Units  specified  by the  Holder  in
     his/her  Cashless  Exercise Form (the "Total  Number")  (such number not to
     exceed  the  maximum  number of Units  subject  to this  Option,  as may be
     adjusted  from  time to time)  less (y) the  number  of Units  equal to the
     quotient  obtained by dividing  (A) the product of the Total Number and the
     existing Per Unit Price by (B) the Market Price Per Unit. "Market Price Per
     Unit"  shall  mean  first,  if there is a trading  market as  indicated  in
     Subsection (A) below for the Units, such Market Price Per Unit and if there
     is no such  trading  market in the Units,  then Market Price Per Unit shall
     equal the sum of the aggregate Market Price of all shares of Common

935424.1

<PAGE>



     Stock (on per share basis,  the "Market  Price Per Share of Common  Stock")
     and Warrants (on a per warrant basis, the "Market Price Per Warrant") which
     comprise a Unit, with the meanings indicated in Subsections (B) through (F)
     below:

               (A) If the Units are listed on a national  securities exchange or
          listed or admitted to unlisted trading  privileges on such exchange or
          listed  for  trading  on the  Nasdaq  National  Market  or the  Nasdaq
          Smallcap Market, the Market Price Per Unit shall be the average of the
          last  reported  sale  prices (or if no last sale,  the last quoted ask
          price) of the Units on such  exchange  or market for the five  trading
          days immediately preceding the Exchange Date; or

               (B) If the  Common  Stock or  Warrants,  as the case may be,  are
          listed on a national  securities  exchange  or  admitted  to  unlisted
          trading  privileges  on such  exchange  or listed  for  trading on the
          Nasdaq National Market or the Nasdaq Smallcap Market, the Market Price
          Per Share of Common Stock, or Market Price Per Warrant,  respectively,
          shall be the average of the last  reported  sale prices (or if no last
          sale,  the last  quoted ask price) of the  Common  Stock or  Warrants,
          respectively,  on such  exchange or market for the five  trading  days
          immediately preceding the Exchange Date; or

               (C) If the Common Stock or Warrants,  as the case may be, are not
          so listed or admitted to unlisted trading privileges, the Market Price
          Per Share of Common Stock, or Market Price Per Warrant,  respectively,
          shall be the last  reported  sale price (or if no last sale,  the last
          quoted   ask  price)  of  the  Common   Stock  or   Warrants   in  the
          over-the-counter  market as reported by the National  Quotation Bureau
          or similar  organization  or in the Pink  Sheets for the  trading  day
          immediately preceding the Exchange Date; or

               (D) If the Common  Stock is not so listed or admitted to unlisted
          trading privileges and the sale price is (or if no last sale, the last
          quoted  ask  price) not so  reported,  the  Market  Price Per Share of
          Common Stock shall be the fair market value as determined by agreement
          between  the Board of  Directors  of the Company and a Majority of the
          Holders; or

               (E) If neither  clause (B) nor (C) applies to the Warrants,  then
          the  Market  Price  Per  Warrant  shall  be an  amount  equal  to  the
          difference  between  (i) the  Market  Price Per Share of Common  Stock
          which may be received upon the exercise of the Warrants, as determined
          in paragraphs (B), (C) and (D) above,  and (ii) the per share exercise
          price of the Warrants then in effect.

               (F) If the Company and the  Majority of the Holders are unable to
          reach  agreement on any  valuation  matter,  such  valuation  shall be
          submitted to and  determined  by a nationally  recognized  independent
          investment  bank selected by the Board of Directors of the Company and
          the Majority of the Holders (or, if such

935424.1

<PAGE>



          selection  cannot be agreed upon promptly,  or in any event within ten
          days,  then such  valuation  shall be made by a nationally  recognized
          independent   investment   banking  firm   selected  by  the  American
          Arbitration  Association  in New  York  City in  accordance  with  its
          rules), the costs of which valuation shall be paid for by the Company.

          (b) If this  Option is  exercised  in part,  the Holder is entitled to
     receive a new Option covering the Units,  which have not been exercised and
     setting  forth  the  proportionate  part  of  the  Aggregate  Option  Price
     applicable to such Units.  Upon surrender of this Option,  the Company will
     (i) issue a certificate or  certificates  in the name of the Holder for the
     largest  number of whole  shares of the Common  Stock and Warrants to which
     the Holder shall be entitled and, if this Option is exercised in whole,  in
     lieu of any fractional  shares of the Common Stock or Warrants to which the
     Holder shall be entitled,  pay to the Holder cash in an amount equal to the
     fair value of such fractional shares  (determined in such reasonable manner
     as the Board of Directors of the Company shall determine), and (ii) deliver
     the other  securities and properties  receivable  upon the exercise of this
     Option,  or the  proportionate  part thereof if this Option is exercised in
     part, pursuant to the provisions of this Option.

          (c) This Option  shall be  exercisable  only for Units  consisting  of
     Warrants and Common Shares at the then applicable Per Unit Price (including
     any adjustment pursuant to Section 3 below).

          (d)  Notwithstanding   anything  to  the  contrary  contained  in  the
     Warrants,  the  following  provisions  shall apply in  connection  with the
     exercise  of the  Warrants  issuable  upon  exercise  of this Option by the
     Holder:

               (i) if all  outstanding  Warrants  are  redeemed  by the  Company
          pursuant  to  Section 7 thereof  or have been  exercised  prior to the
          exercise of this  Option,  the Holder shall be entitled to receive the
          Common  Stock  otherwise   issuable  upon  exercise  of  the  Warrants
          underlying  this option (or the portion of this Option  exercised)  by
          giving written notice of exercise of such Warrants simultaneously with
          exercise  of this  Option,  which  notice  shall  specify  whether the
          Warrants  are being such  exercised  for a cash payment or by cashless
          exercise  and the  number  shares  of  Common  Stock as to which  such
          Warrants are being  exercised,  and if the exercise is for cash, shall
          be accompanied  by the payment  required on exercise of such Warrants.
          If all of the  outstanding  Warrants  have been  redeemed  pursuant to
          Section 7 thereof or have been exercised prior to the exercise of this
          Option and the Holder does not  exercise the  Warrants  issuable  upon
          exercise hereof  simultaneously with exercise of this Option, then the
          Holder on  exercise of this  Option  shall only  receive the number of
          shares of the Common Stock  included in the Units issuable on exercise
          of this Option (or the portion of this Option exercised) and shall not
          be issued any Warrants.


935424.1

<PAGE>



               (ii)  Notwithstanding  anything to the contrary  contained in the
          Warrants, the Holder may exercise the Warrants by cashless exercise by
          using the same  formula as set forth for  exercise  of this  Option by
          cashless exercise in Section 1(a)(ii) of this Option (except that, for
          this  purpose,  any  reference to the Warrants or the Market Price Per
          Warrant in Section 1(a)(ii) shall be inapplicable).


         2.  Reservation  of  Warrant  Shares and Common  Shares;  Listing.  The
Company agrees that, prior to the expiration of this Option, the Company will at
all times (a) have authorized and in reserve,  and will keep  available,  solely
for  issuance and delivery  upon the  exercise of this  Option,  the Units,  the
Warrants and the Common Shares  underlying  such Units and other  securities and
properties  as from time to time shall be  receivable  upon the exercise of this
Option, free and clear of all restrictions on sale or transfer, other than under
Federal or state  securities  laws, and free and clear of all preemptive  rights
and rights of first  refusal and (b) have  authorized  and in reserve,  and will
keep  available,  solely for issuance or delivery upon exercise of the Warrants,
the shares of Common Stock,  the Warrant  Shares and the Common Shares and other
securities  and  properties as from time to time shall be  receivable  upon such
exercise,  free and clear of all  restrictions  on sale or transfer,  other than
under Federal or state  securities  laws,  and free and clear of all  preemptive
rights  and  rights  of first  refusal;  and (c) if the  Company  is  listed  or
hereafter lists its Common Stock on any national securities exchange, the Nasdaq
National Market or the Nasdaq Smallcap Market,  use its best efforts to keep the
Common Shares authorized for listing on such exchange upon notice of issuance.

         3. Protection Against Dilution.
            ---------------------------

         (a) The  anti-dilution  provisions  of the Warrants  shall  protect the
Holder from  dilution of the  purchase  rights  represented  by the Warrants (it
being  understood  for this  purpose  that the Holder shall be deemed to own the
Warrants   commencing   on  December  28,   1999);   provided,   however,   that
notwithstanding  anything to the contrary  contained in the Warrants,  if all of
the Warrants have been  redeemed or exercised  prior to exercise of this Option,
the Holder  shall not be entitled  to any  adjustment  in the Per Share  Warrant
Price  pursuant to Section  3(c) of the  Warrants  as a result of any  issuances
subsequent to the date of the  redemption of the Warrants  pursuant to Section 7
of the Warrants.  In addition,  the  following  anti-dilution  provisions  shall
protect the Holder from dilution resulting from the issuance of Common Stock and
other securities:

                  (i) If the Company shall issue or distribute to the holders of
         shares  of  Common  Stock  evidence  of  its  indebtedness,  any  other
         securities  of the  Company  or any  cash,  property  or  other  assets
         (excluding a subdivision, combination or reclassification,  or dividend
         or  distribution  payable  in shares of Common  Stock,  referred  to in
         Subsection  3(a)(ii),   and  also  excluding  cash  dividends  or  cash
         distributions paid out of net profits legally available therefor in the
         full amount thereof (any such non-excluded  event being herein called a
         "Common Stock Special Dividend")), the Per Unit Price shall be adjusted
         by multiplying the Per Unit Price then in effect by a fraction, (A) the
         numerator of which shall be (x) the then current

935424.1

<PAGE>



         Market  Price Per Share of Common Stock in effect on the record date of
         such  issuance  or  distribution  less (y) the fair  market  value  (as
         determined  in good faith by the  Company's  Board of Directors) of the
         evidence of indebtedness, cash, securities or property, or other assets
         issued or distributed in such Common Stock Special Dividend  applicable
         to one share of Common Stock and (B) the  denominator of which shall be
         the then  current  Market  Price Per Share of Common Stock in effect on
         the record date of such issuance or  distribution.  An adjustment  made
         pursuant to this Subsection 3(a)(i) shall become effective  immediately
         after the record date of any such Common Stock Special Dividend.

                  (ii)  If the  Company  shall  (A)  pay a  dividend  or  make a
         distribution  on its  capital  stock in  shares of  Common  Stock,  (B)
         subdivide its outstanding  shares of Common Stock into a greater number
         of shares,  (C) combine its  outstanding  shares of Common Stock into a
         smaller number of shares or (D) issue by reclassification of its Common
         Stock any shares of capital  stock of the  Company,  the Per Unit Price
         shall be adjusted by multiplying the Per Unit Price by a fraction,  the
         numerator  of which  shall be the  number of Common  Shares  which this
         Option was  exercisable for prior to such action and the denominator of
         which shall be the number of Common  Shares  which a Holder  would have
         owned immediately  following such action had such Option been exercised
         immediately  prior  to  the  record  or  effective  date  therefor.  An
         adjustment  made  pursuant to this  Subsection  3(a)(ii)  shall  become
         effective  immediately  after the record date in the case of a dividend
         or  distribution  and  shall  become  effective  immediately  after the
         effective   date  in  the  case  of  a   subdivision,   combination  or
         reclassification.

         (b) No adjustment  in the Per Unit Price shall be required  unless such
adjustment  would  require an  increase  or decrease of at least $0.05 per Unit;
provided, however, that any adjustments which by reason of this Section 3(b) are
not  required to be made shall be carried  forward and taken into account in any
subsequent  adjustment;  provided,  further,  however, that adjustments shall be
required and made in  accordance  with the  provisions  of this Section 3 (other
than this Subsection  3(b)) not later than such time as may be required in order
to preserve the tax-free  nature of a distribution to the Holder of this Option.
All  calculations  under this  Section 3 shall be made to the nearest cent or to
the nearest  1/100th of a share,  as the case may be. Anything in this Section 3
to the  contrary  notwithstanding,  the  Company  shall be entitled to make such
reductions in the Per Unit Price,  in addition to those required by this Section
3, as it in its  discretion  shall deem to be  advisable in order that any stock
dividend,  subdivision of shares or  distribution of rights to purchase stock or
securities  convertible or exchangeable  for stock hereafter made by the Company
to its stockholders shall not be taxable.

         (c) Whenever the Per Unit Price is adjusted as provided in this Section
3 and upon any  modification  of the rights of a Holder of Options in accordance
with this Section 3, the Company shall promptly prepare a brief statement of the
facts requiring such adjustment or modification  and the manner of computing the
same and cause  copies of such  certificate  to be mailed to the  Holders of the
Options.  The Company may, but shall not be obligated to unless requested by the
Holders of

935424.1

<PAGE>



more  than  fifty  percent  (50%) of the  outstanding  Options,  obtain,  at its
expense, a certificate of a firm of independent public accountants of recognized
standing  selected by the Board of Directors (who may be the regular auditors of
the  Company)  setting  forth  the Per Unit  Price and the  number of  Warrants,
Warrant  Shares or Common Shares,  as the case may be, after such  adjustment or
the effect of such  modification,  a brief statement of the facts requiring such
adjustment or modification and the manner of computing the same and cause copies
of such certificate to be mailed to the Holders of the Options.

         (d) If the Board of Directors of the Company shall declare any dividend
or other  distribution  with  respect  to the  Common  Stock  other  than a cash
distribution out of earned surplus, the Company shall mail notice thereof to the
Holders of the  Options not less than 10 days prior to the record date fixed for
determining  stockholders  entitled  to  participate  in such  dividend or other
distribution.

         (e) In case of any capital  reorganization or reclassification,  or any
consolidation  or merger to which the  Company is a party other than a merger or
consolidation in which the Company is the continuing corporation,  or in case of
any sale or  conveyance  to another  entity of the property of the Company as an
entirety  or  substantially  as a  entirety,  or in the  case  of any  statutory
exchange of securities with another corporation (including any exchange effected
in connection with a merger of a third corporation into the Company), the Holder
of this Option  shall have the right  thereafter  to receive on the  exercise of
this Option the kind and amount of securities,  cash or other property which the
Holder would have owned or have been entitled to receive  immediately after such
reorganization,  reclassification,  consolidation,  merger,  statutory exchange,
sale or  conveyance  had this Option  been  exercised  immediately  prior to the
effective date of such reorganization, reclassification,  consolidation, merger,
statutory  exchange,  sale or  conveyance  and in any such case,  if  necessary,
appropriate  adjustment  shall be made in the  application of the provisions set
forth in this Section 3 with respect to the rights and  interests  thereafter of
the  Holder  of this  Option  to the end that the  provisions  set forth in this
Section 3 shall thereafter  correspondingly be made applicable, as nearly as may
reasonably  be,  in  relation  to any  shares  of stock or other  securities  or
property  thereafter  deliverable  on the  exercise  of this  Option.  The above
provisions  of  this   Subsection  3(e)  shall  similarly  apply  to  successive
reorganizations,    reclassifications,    consolidations,   mergers,   statutory
exchanges,  sales or  conveyances.  The Company  shall require the issuer of any
shares of stock or other  securities or property  thereafter  deliverable on the
exercise  of  this  Option  to be  responsible  for  all of the  agreements  and
obligations  of  the  Company  hereunder.  Notice  of any  such  reorganization,
reclassification,  consolidation, merger, statutory exchange, sale or conveyance
and of said provisions so proposed to be made, shall be mailed to the Holders of
the  Options  not  less  than 30 days  prior  to  such  event.  A sale of all or
substantially  all of the assets of the Company for a  consideration  consisting
primarily  of  securities  shall be deemed a  consolidation  or  merger  for the
foregoing purposes.

         (f) If, as a result of an  adjustment  made pursuant to this Section 3,
the  Holder of any Option  thereafter  surrendered  for  exercise  shall  become
entitled to receive  shares of two or more classes of capital stock or shares of
Common  Stock and other  capital  stock of the  Company,  the Board of Directors
(whose determination shall be conclusive and shall be described in a written

935424.1

<PAGE>



notice  to the  Holder of any  Option  promptly  after  such  adjustment)  shall
determine the  allocation of the adjusted Per Unit Price between or among shares
or such  classes of capital  stock or shares of Common  Stock and other  capital
stock.

         (g) Upon the expiration of any rights, options,  warrants or conversion
privileges,  if such  shall  not  have  been  exercised,  the  number  of  Units
purchasable upon exercise of this Option, to the extent this Option has not then
been exercised,  shall, upon such expiration, be readjusted and shall thereafter
be such as they would have been had they been  originally  adjusted  (or had the
original  adjustment not been required,  as the case may be) on the basis of (i)
the fact that Common Stock, if any, actually issued or sold upon the exercise of
such rights, options, warrants or conversion privileges,  and (ii) the fact that
such shares of Common Stock,  if any, were issued or sold for the  consideration
actually received by the Company upon such exercise plus the  consideration,  if
any,  actually  received by the Company for the  issuance,  sale or grant of all
such  rights,  options,   warrants  or  conversion  privileges  whether  or  not
exercised; provided, however, that no such readjustment shall have the effect of
decreasing  the number of Units  purchasable  upon exercise of this Option by an
amount in excess of the amount of the  adjustment  initially  made in respect of
the  issuance,  sale or grant of such rights,  options,  warrants or  conversion
privileges.

         (h) Whenever the Per Unit Price payable upon exercise of each Option is
adjusted  pursuant to this  Section 3, (i) the number of shares of Common  Stock
included in a Unit shall simultaneously be adjusted by multiplying the number of
shares of Common Stock included in a Unit  immediately  prior to such adjustment
by the Per Unit  Price  in  effect  immediately  prior  to such  adjustment  and
dividing the product so obtained by the Per Unit Price, as adjusted and (ii) the
number of shares of Common Stock or other  securities  issuable upon exercise of
the Warrants  included in the Units and the exercise  price  payable for each of
the Warrant Shares  (initially  $0.50 per Warrant Share,  subject to adjustment)
pursuant to the Warrant terms shall be adjusted in accordance  with the terms of
the Warrant Agreement applicable to holders of such Warrants.

         (i) In case any event shall occur as to which the other  provisions  of
this Section 3 are not strictly  applicable  but as to which the failure to make
any adjustment would not fairly protect the purchase rights  represented by this
Option in accordance  with the essential  intent and principles  hereof then, in
each such  case,  the Board of  Directors  of the  Company  shall in good  faith
determine  the  adjustment,  if any, on a basis  consistent  with the  essential
intent and  principles  established  herein,  necessary to preserve the purchase
rights  represented by the Options.  Upon such  determination,  the Company will
promptly  mail a copy  thereof to the Holder of this  Warrant and shall make the
adjustments described therein.

         4. Fully Paid  Stock;  Taxes.  The  Company  agrees  that the shares of
theCommon  Stock  represented  by each and every  certificate  for Common Shares
delivered  on the  exercise  of this  Option  and the  shares  of  Common  Stock
delivered upon the exercise of the Warrants, shall at the time of such delivery,
be validly issued and outstanding, fully paid and nonassessable, and not subject
to preemptive  rights or rights of first refusal,  and the Company will take all
such actions as may be  necessary to assure that the par value or stated  value,
if any,  per share of the Common Stock is at all times equal to or less than the
then Per Unit Price. The Company further

935424.1

<PAGE>



covenants and agrees that it will pay, when due and payable, any and all Federal
and state stamp, original issue or similar taxes which may be payable in respect
of the issue of any Warrant Share,  Common Share or any  certificate  thereof to
the extent required because of the issuance by the Company of such security.

         5. Registration Under Securities Act of 1933.
            -----------------------------------------

         (a) The Holder shall,  with respect to the Common Shares only, have the
right  to  participate  in  the  registration   rights  granted  to  holders  of
Registrable Securities pursuant to Section 5 of the subscription agreements (the
"Subscription  Agreements")  between  such  holders  and the  Company  that were
entered into at the time of the initial sale of the Units. By acceptance of this
Option,  the Holder  agrees to comply  with the  provisions  in Section 5 of the
Subscription Agreement to same extent as if he/she were a party thereto.

         (b) Until all Common  Shares and Warrant  Shares have been sold under a
Registration  Statement or pursuant to Rule 144 under the Act, the Company shall
use its  reasonable  best  efforts  to file  with the  Securities  and  Exchange
Commission all current reports and the information as may be necessary to enable
the  Holder  to  effect  sales of  his/her  shares  in  reliance  upon  Rule 144
promulgated under the Act.

         6. Investment Intent; Limited Transferability.

         (a) The Holder  represents,  by  accepting  this  Option,  that  he/she
understands that this Option and any securities obtainable upon exercise of this
Option have not been registered for sale under Federal or state  securities laws
and are being offered and sold to the Holder  pursuant to one or more exemptions
from the registration requirements of such securities laws. In the absence of an
effective  registration  of  such  securities  or an  exemption  therefrom,  any
certificates  for such  securities  shall bear the legend set forth on the first
page hereof.  The Holder  understands that he/she must bear the economic risk of
his/her investment in this Option and any securities obtainable upon exercise of
this Option for an indefinite period of time, as this Option and such securities
have not been  registered  under Federal or state  securities laws and therefore
cannot  be sold  unless  subsequently  registered  under  such  laws,  unless an
exemption from such registration is available.

         (b) The Holder, by his acceptance of his/her Option,  represents to the
Company  that he/she is acquiring  this Option and will  acquire any  securities
obtainable  upon exercise of this Option for his/her own account for  investment
and not with a view to, or for sale in connection with, any distribution thereof
in  violation  of the Act.  The  Holder  agrees  that this  Option  and any such
securities will not be sold or otherwise  transferred  unless (i) a registration
statement  with  respect to such  transfer  is  effective  under the Act and any
applicable  state securities laws or (ii) such sale or transfer is made pursuant
to one or more exemptions from the Act.

         (c) This Option may not be sold, transferred,  assigned or hypothecated
for six months from the date hereof except (i) to any firm or  corporation  that
succeeds to all or substantially all of the business of Paramount Capital, Inc.,
(ii) to any of the officers, employees, associates or affiliated

935424.1

<PAGE>



companies of Paramount  Capital,  Inc., or of any such successor firm,  (iii) to
any NASD member  participating in the Offering or any officer or employee of any
such  NASD  member  or  (iv)  in the  case of an  individual,  pursuant  to such
individual's  last will and  testament or the laws of descent and  distribution,
and is so  transferable  only upon the books of the Company which it shall cause
to be maintained for such purpose.  The Company may treat the registered  Holder
of this  Option  as he/she  appears  on the  Company's  books at any time as the
Holder for all  purposes.  The Company  shall  permit any Holder of an Option or
his/her duly authorized attorney,  upon written request during ordinary business
hours,  to  inspect  and  copy or make  extracts  from  its  books  showing  the
registered  holders  of  Options.  All  Options  issued  upon  the  transfer  or
assignment  of this Option will be dated the same date as this  Option,  and all
rights of the holder thereof shall be identical to those of the Holder.

         7. Loss, etc., of Option. Upon receipt of evidence  satisfactory to the
Company of the loss,  theft,  destruction  or mutilation of this Option,  and of
indemnity reasonably  satisfactory to the Company, if lost, stolen or destroyed,
and upon surrender and  cancellation of this Option,  if mutilated,  the Company
shall  execute  and  deliver to the Holder a new Option of like date,  tenor and
denomination.

         8. Option Holder Not Stockholder.  This Option does not confer upon the
Holder any right to vote or to consent to or receive  notice as a stockholder of
the Company, as such, in respect of any matters whatsoever,  or any other rights
or liabilities as a stockholder, prior to the exercise hereof; this Option does,
however,  confer  certain rights and require  certain  notices to Holders as set
forth herein.

         9.  Communication.  No notice or other  communication under this Option
shall be  effective  unless,  but any  notice  or other  communication  shall be
effective  and shall be deemed to have been given if, the same is in writing and
is mailed by first-class mail, postage prepaid, addressed to:

          (a) the Company at  Discovery  Laboratories,  Inc.,  3359 Durham Road,
     Doylestown,  Pennsylvania,  18901,  Attn: Vice  President,  Finance or such
     other address as the Company has designated in writing to the Holder, or

          (b) the Holder at c/o Paramount Capital, Inc., 787 Seventh Avenue, New
     York,  NY 10019 or other  such  address as the  Holder  has  designated  in
     writing to the Company.

         10.  Headings.  The  headings of this  Option  have been  inserted as a
matter of convenience and shall not affect the construction hereof.

         11.  Applicable  Law.  This Option  shall be governed by and  construed
inaccordance  with the law of the State of New York without giving effect to the
principles of conflicts of law thereof.

         12.  Amendment,  Waiver,  etc.  Except as  expressly  provided  herein,
neither this Option nor any term hereof may be amended,  waived,  discharged  or
terminated other than by a written  instrument  signed by the party against whom
enforcement of any such amendment,  waiver,  discharge or termination is sought;
provided, however, that any provisions hereof may be amended, waived, discharged
or  terminated  upon the written  consent of the  Company  and the then  current
Majority of the Holders of the Options only.

Dear Dr. Martin:

         Reference is herein made to the License Agreement dated as of March 20,
1996 by and between The Charlotte-Mecklenburg Hospital Authority and Discovery
Laboratories, Inc., as successor-in-interest to Triad Pharmaceuticals and as
amended by an Amendment Letter dated July 18, 1996 and as further amended by an
Amendment Letter dated August 8, 1996 and as further amended by an Amendment
Letter dated December 9, 1996 (collectively, the "License Agreement").

         Licensor and Licensee hereby agree to further amend the License
Agreement as follows:

         1.       Section 3.4 is hereby amended and restated as follows:

                  "In the event[***], then Licensee shall on [***] pay to
                  Licensor a nonrefundable, one-time, additional license fee in
                  the amount of [***] to maintain its rights under this
                  Agreement for one additional year. On each subsequent
                  anniversary of [***] thereafter, if [***], then Licensee will
                  pay an additional [***] for each further annual extension of
                  the License Agreement. Licensee's failure to pay any such
                  additional license fee shall constitute a material breach or
                  default for purposes of the termination provisions of
                  Paragraph 7.3."

of Licensee's notice, the parties shall engage in exclusive, good-faith
negotiations for the terms upon which Licensor would appoint Licensee as the

product in the Licensed Territory with a third party on terms which, taken as a
whole, are more favorable to such third party than those last offered in writing
by Licensor to Licensee for such product.

         each of Licensee and Licensor. The Committee shall be chaired by a
         designee of Licensor. In the event of any deadlock or other inability
         of the Committee to reach a determination with respect to any matter
         within the authority of the Committee, the issue shall be referred to
         the respective Chief Executive Officers or General Managers of each
         party who shall use their best endeavours to agree in good faith to a
         resolution of the dispute within thirty (30) days of their receipt of
         notice as to such dispute. If they are unable to resolve the dispute
         within such thirty (30) day period, it shall be referred to the
         decision of an external expert suitably qualified to resolve such
         dispute which is mutually acceptable to both parties, whose decision
         shall be final. In resolving the dispute, the appointed expert shall
         take into account clinical development practices and procedures common
         in the pharmaceutical industry.

                  (c) The initial members of the Committee shall be designated

         in place of the absent representative. In addition, each party may,
         with the consent of the other party, invite consultants or scientific
         advisors to attend meetings of the Committee.

                  (f) The Committee will report to Licensor and Licensee

first commercial sale of each Licensed Product in each country of the Licensed
Territory within ninety (90) days after obtaining Pricing Approval (or if
Pricing Approval is not applicable, within ninety (90) days of Marketing
Regulatory Approval in such country); provided, however, that if Licensee has
failed to meet such deadlines in any country because of reasons beyond the
control of Licensee, Licensor and Licensee shall discuss in good faith a new
deadline for such country. In the event Licensee does not consummate a sale
within such period, Licensor may notify Licensee of a default under this Section
5.5 and, in the event such default is not cured within thirty (30) days from
such notice of default, Licensor shall have the right to terminate the license
granted to Licensee hereunder with respect to such Licensed Product in such
country.

         Section 5.6. Commencement of Marketing; Post-Commencement Trials.
Licensee shall be responsible for conducting, at its own cost and expense such

accordance with Section 5.3(b) in advance of its commencement. Licensor and
Licensee shall monitor and supervise the conduct thereof following commencement.

reasonable efforts to commercialize the Licensed Products in the Licensed
Territory throughout the term of this Agreement in accordance with all
applicable legal and regulatory requirements, including promoting the Licensed
Products by accepted promotional practices consistent with those used (i) by
Licensee in connection with the promotion of its other products and (ii) in the
critical care pharmaceutical industry generally.

                  (b) From and after the date that an NDA with respect to any

         Section 5.8. Product Failure. In the case of a Product Failure with
respect to an Indication in any country, the Committee shall seek to identify a

Indication in the country or countries in which such Product Failure occurred.
In the event a Replacement Product has not been identified for development in
writing by the Committee within one year of such Product Failure, either party
shall have the right to terminate this Agreement with respect to such Indication
in such country or countries within 30 days following expiration of such
one-year period by written notice to the other party. The Committee shall

following its identification, which shall include provisions for the funding of
Development Costs with respect to such Replacement Product by Licensor, Licensee

Licensor or its licensees intend to commercialize such Replacement Product. In
the event the Committee has not reached agreement upon such development plan,
including the funding of Development Costs, within 90 days after identification
of a Replacement Product for development hereunder, then either party shall have
the right to terminate this Agreement with respect to such Indication in such
country or countries by written notice to the other within the 30 days following
expiration of such 90-day period; provided, however, than in such event,
Licensor shall not enter into any agreement relating to the development,
distribution, marketing and sale of the same product in the Licensed Territory
with a third party on terms which, taken as a whole, are more favorable to such
third party than those last offered in writing by Licensor for such product.

         Section 5.9. Medico-Marketing Plan. Licensee shall submit to Licensor a
medico-marketing plan for the Licensed Products (the "Development Plan") as soon
as possible, but in any event no later than ninety (90) days prior to the

is an infringement of the Licensed Rights by a third party hereto selling
material quantities of products in the Licensed Territory in competition with

settle any such proceedings brought by it without obtaining the concurrence of
the other party if such action would impose any obligations on such other party
or affect the exercise of the rights granted hereunder to such other party
(which concurrence shall not be unreasonably withheld).

         Section 8.5. Recoveries. All damages, settlements and awards made or
obtained in connection with any suit or other legal proceeding under

         Section 9.1. Non-Use. Subject to the licenses expressly granted
hereunder with respect to the Trademark, nothing contained in this Agreement

abbreviation or simulation of any of the foregoing) without the prior, written
consent of the other.

         Section 9.2. Relationship. Nothing herein shall be deemed to establish
a relationship of principal and agent between Licensor and Licensee, nor any of
their agents or employees for any purpose whatsoever. This Agreement shall not
be construed as constituting Licensor and Licensee as partners, or as creating
any other form of legal association or arrangement which would impose liability

                                   ARTICLE 10

and Scripps) to an ownership interest in the Licensed Rights licensed to
Licensee under this Agreement.

                  (c) Licensor has obtained any required third-party consents
         under contracts to which Licensor or any of its Affiliates is a party

         hereunder and thereunder.

                  (d) To Licensor's knowledge, based solely on a review of the
         records of the United States Patent and Trademark Office and the
         corresponding offices in countries other than the United States, the

         property rights of any third parties or advised Licensor or any of its
         Affiliates in writing that it intends to pursue any such claim,
         lawsuit, charge, complaint or other action. Licensor has not, prior to
         the date hereof, entered into any compulsory license with a third party

                  (f) The rights of the Original Licensor and of any subsequent
         licensor (excluding the Licensor) of the Scripps Patent Rights do not
         prevent the grant of the license made hereunder nor do such rights
         permit any such person to sell (directly or indirectly) or license for
         sale surfactant pharmaceutical preparations based on or embodying the
         Patent Rights in the Licensed Territory or enable such person to demand
         any indemnity, royalty or compensation of whatever nature from Licensee
         as a result of Licensee's sales of Licensed Products in the Licensed
         Territory in accordance with the terms of this Agreement.

                  (g) Licensor is not in breach of any of its obligations under
         the Original License as of the date hereof.

                  (h) All of Licensor's employees having access to any
         confidential information with respect to the Licensed Rights are
         subject to written confidentiality obligations with respect to the
         disclosure of such information.

                  (i) Prior to the execution of this Agreement it has disclosed
         to Licensee all material information pertaining to the Licensed
         Products and the Patent Rights reasonably relevant to Licensee in order
         to assess its interest in entering into this Agreement, and that no
         material information pertaining to the Licensed Products and the Patent
         Rights actually known to Licensor as of the Effective Date regarding
         the foregoing has been withheld from Licensee by Licensor.

contradiction between the Supply Agreement


                                       24
<PAGE>


and any of the terms contained in this Sublicense Agreement, the terms of this
Agreement shall prevail.

         Section 11.3. Insurance. Licensor and Licensee shall maintain during
the term of this Agreement insurance policies covering their respective

         Section 12.1. Trademarks Used in Connection With Licensed Products. (a)

         expense, to register, maintain and renew registrations of the Trademark
         in the Licensed Territory, to the extent that it is necessary for the
         purposes of obtaining Marketing Regulatory Approval and for the
         marketing of the Licensed Products in the Licensed Territory. Licensee
         agrees not to take any actions (including without limitation effecting
         any trademark registrations) inconsistent with the foregoing and not to
         register anywhere in the world any trademark confusingly similar to
         Surfaxin(R) or any derivative thereof.

                  (c) Licensee agrees to take such actions as may be reasonably

         any Trademark at the sole cost and expense of Licensor.

(collectively, the "Third Party Patent Rights")


                                       25
<PAGE>


that the Original Licensor will maintain the Third Party Patent Rights or, in
the event that the Original Licensor does not do so, that Licensor shall be
given the right to do so. Licensor undertakes to enforce its rights with respect
to maintenance of the Third Party Patent Rights against the Original Licensor
and, to the extent Licensor succeeds to the maintenance of the Third Party
Patent Rights, to use all commercially reasonable efforts to do so. Licensor
further undertakes to maintain the Patent Rights owned by Licensor. Licensor
shall provide Licensee with copies of all written materials received by Licensor
from the Original Licensor, the Original Licensor's or Licensor's counsel, or
any governmental agency or instrumentality relating to prosecution and/or
maintenance of Patent Rights and shall afford Licensee the opportunity to review

the case of the Third Party Patent Rights, to the same extent Licensor is
entitled to do so).

of Member States of the European Community and other similar measures in any
country. Without limiting the foregoing, Licensee agrees to timely supply

filed (or to permit the Original Licensor to file or have filed) an application
for patent term extension within the 60-day period following U.S. NDA approval.
The same shall apply with respect to the approval by health regulatory
authorities in a country of the European Community or approval by the
appropriate authorities in any other country in the Licensed Territory.

                                Rejection.

                                   (a) Seller agrees to sell to Buyer such

         accepted" written thereon by Seller. Except as aforesaid, this

                                   (e) Buyer may reject any portion of any
         shipment of Licensed Product which does not conform with the
         Specifications. In order to reject a shipment, Buyer must (i) give
         notice to Seller of Buyer's intent to reject the shipment within 30
         days of receipt together with a detailed written indication of the
         reasons for such possible rejection, and (ii) as promptly as reasonably
         possible thereafter, but in any event within an additional thirty (30)
         days, provide Seller with notice of final rejection and the full basis
         therefor. After notice of intent to reject is given, Buyer shall
         cooperate with Seller in determining whether rejection is necessary or
         justified. If such notices of intent to reject and final rejection are
         not timely received, Buyer shall be deemed to have accepted such
         delivery of Licensed Product and to have waived all claims for
         non-conformity with the Specifications, damage, defect or shortage,
         other than claims for latent defects not capable of discovery by Buyer
         upon physical examination. In the event of latent defects not capable
         of discovery by Buyer upon physical examination, Buyer shall inform
         Seller within fifteen (15) days of discovering any such defect. Buyer
         shall be entitled to a refund of the purchase price (together with
         insurance, freight charges and, where applicable, custom duties) of
         properly rejected Licensed Products at the time they are ultimately
         rejected, provided that if Seller disputes the rejection, refund shall
         be made, if at all, at the time the dispute is finally resolved. Seller
         shall notify Buyer as promptly as reasonably possible (but in any event
         no later than thirty (30) days after receipt of Buyer's final rejection
         notice) whether it accepts Buyer's basis for any rejection. In the
         event Seller disputes Buyer's rejection, the parties will select a
         mutually agreeable independent third party laboratory which shall
         determine whether the rejected Licensed Products meet the applicable
         Specifications and shall confirm or dissent from Buyer's rejection of
         Licensed Products. If the parties are unable to agree on a laboratory
         firm within thirty (30) days after receipt of Buyer's final rejection
         notice, the laboratory shall be appointed by computer generation of a
         random number, with an even number signifying Seller's right to
         designate the laboratory and an odd number designating Buyer's right to
         designate the laboratory. If the independent tester confirms Buyer's
         rejection, Seller will pay the fees of the tester, and if the tester
         dissents from Buyer's rejection, Buyer will pay the fees.

                                   (f) Whether or not Seller accepts Buyer's
         basis for rejection, promptly on receipt of a notice of rejection,
         Seller shall use its commercially reasonable efforts, at Buyer's
         request, to provide replacement Licensed Product, which shall be
         purchased by Buyer as provided in this Agreement as soon as reasonably
         practicable.

                                   (g) Unless Seller requests the return to it
         of a rejected batch within 60 days of receipt of Buyer's notice of
         rejection, Buyer shall, at Seller's cost, destroy such batch promptly
         and provide Seller with certification

935303.1

                                       4

         of such destruction. Buyer shall, upon receipt of Seller's request for
         return, promptly dispatch said batch to Seller, at Seller's cost.

                                   (h) No change to the Specifications shall be
         effective unless the same shall be required or permitted by any
         regulatory agency having jurisdiction over any country in the Licensed
         Territory, Buyer or the Licensed Products (and if not required, shall
         be agreed to in writing by Buyer and Seller). Seller shall give Buyer
         advance notice of any change to the Specifications required by a
         regulatory agency.

                  2.2 Price; Method of Payment.

                           (a) Buyer shall purchase Licensed Products from
         Seller hereunder at the applicable Transfer Price. The Transfer Price
         for each unit of Licensed Product shall equal [***], subject to
         paragraph (d) below.

                           (b) Seller shall invoice Buyer for each shipment of
         Licensed Products delivered by Seller to Buyer, its Affiliates or
         sublicensees at the Transfer Price converted into U.S. dollar at the
         exchange rate of the last Business Day of the calendar month
         immediately preceding the month when the Licensed Product is shipped to
         Licensee, as quoted by the Wall Street Journal.

                           (c) Buyer shall pay Seller's invoices in U.S. Dollar
         not later than ninety (90) days following the date of the applicable
         invoice by wire transfer to the bank account designated by Seller.

                           (d) In the event that the Transfer Price of any
         Licensed Product represents more than [***], Licensor and Licensee
         shall, at Licensee's request, hold good faith discussions in order to
         adjust the Transfer Price with respect to Licensed Product sales in
         such country.

                           (e) All payments under this Section 2.2 shall be free
         of all withholdings of any nature whatsoever (including, without
         limitation, withholding taxes, monetary transfer fees, or similar taxes
         and charges), and in the event any withholding is required, Buyer shall
         pay the same together with such additional amount as is required so
         that each such payment shall be, under any circumstances and in any
         event, in the amount as set forth or referred to herein.

                  Section 3.1. Manufacturing of Licensed Products.

                           (a) Until such time, if any, as a Seller-owned
         manufacturing facility (an "Owned Facility") is qualified for the
         manufacture of Licensed Products sold to Buyer hereunder, Seller shall
         manufacture or have manufactured the Licensed Products sold to Buyer
         hereunder at a contract manufacturing facility (a "Contract Facility")

         that such date of First Commercial Sale has been communicated to Seller

         Licensed Products sold to Buyer hereunder, which alternate production
         site, if a Contract Facility, shall [***]. Seller's obligation to
         maintain an alternate manufacturing facility may also be satisfied
         through a sublicensing arrangement complying with Section 3.2.

                           (b) Seller shall be responsible for obtaining and
         maintaining all necessary licenses, registrations, authorizations and
         approvals (other than such licenses, registrations, authorizations and
         approvals that are required to be obtained or made by an owner or
         operator of a Contract Facility) which are necessary to manufacture,
         handle, store, label, package, transport and ship Licensed Products
         under cGMP conditions and in accordance with other regulatory
         requirements.

                           (c) Seller shall provide Buyer with copies of any
         correspondence sent from Seller to governmental entities relating to
         the manufacturing, handling, storage, labeling, packaging,
         transportation or shipment of Licensed Products at the time such
         correspondence is sent by Seller, purged of Seller proprietary and/or
         confidential information and trade secrets. Seller shall provide Buyer
         with copies of any comments, responses, notices or other correspondence
         received by Seller from any governmental entity relating to the
         foregoing matters within fifteen (15) days of receipt of such
         correspondence by Seller, purged of any Seller proprietary information
         and/or trade secrets.

                           (d) Seller shall furnish to Buyer (i) promptly, but

         party authorized by

         to any Owned Facility or, to the extent Seller is provided with such
         information, any Contract Facility, including but not limited to, any
         FDA Form 483 or warning letter and (ii) not later than fifteen (15)
         days after the time Seller provides such to a governmental entity,
         summaries of any and all proposed responses or explanations relating
         thereto (each, a "Proposed Response"), in each case purged of trade
         secrets or other confidential or proprietary information of Seller.
         After the filing of a response with the appropriate governmental
         entity, Seller will notify Buyer of any further oral and/or written
         contacts with a governmental entity (or a third party authorized by a
         governmental entity) relating to the manufacturing, handling, storage,
         labeling, packaging, transportation or shipment of Licensed Products.

                           (e) If requested in writing by Buyer, Seller shall
         permit Buyer to inspect, once per year, during normal business hours
         and hours during which Seller is manufacturing Licensed Products,
         Seller's Facilities and manufacturing records to the extent Buyer deems
         it reasonably necessary to enable Buyer to verify compliance with any
         statutory or regulatory requirements to which Buyer is subject and
         which are applicable to the manufacture and/or packaging of Licensed
         Products. Notwithstanding the foregoing, Buyer shall have the right to
         inspect Seller's Facilities and manufacturing records at any time, in
         the event that there is a quality or regulatory problem with any
         Licensed Product. If, as a result of any such inspection, Buyer
         concludes that Seller is not in compliance with any regulatory
         obligations or requirements applicable to Buyer, Buyer shall so notify
         Seller in writing, specifying such areas of noncompliance in reasonable
         detail and Seller shall remedy the problems identified.

                           (f) Seller agrees to use all reasonable efforts to
         promptly rectify or resolve any deficiencies noted by a governmental
         entity (or third party authorized by a governmental entity) in a report
         or correspondence issued to Seller with respect to an Owned Facility or
         a Contract Facility.

                  It is understood and agreed that Seller shall have the right
in connection with its performance hereunder to contract with such third parties
as Seller deems advisable to manufacture Licensed Products, provided that (i)
manufacture and/or quality control by any such third party has been authorised
by the competent regulatory authorities in the Licensed Territory, (ii) Seller
shall provide Buyer with not less than fifteen (15) days' advance notice of its
intent to contract with any third party and shall identify such third party to
Buyer, (iii) Buyer may audit Seller's contractor's qualifications and (iv)
Seller shall remain fully liable for its performance hereunder to the same
extent as if such contractor had not been engaged.

                  Section 3.3.  Exclusivity.

                  For so long as the Sublicense Agreement remains in effect with
respect to any country in the Licensed Territory, until such time as Buyer has a
fully paid-up license in such country in accordance with the terms of the
Sublicense Agreement, Seller shall supply Licensed Products only to Buyer for
distribution within such country.

                  Section 3.4.  Alternate Sources of Supply.

                  In the event Seller is unable to supply conforming Licensed
Products sufficient to meet Buyer's firm orders made consistent with Section
4.1, Buyer shall have the immediate right to manufacture and package Licensed
Product with a supplier other than Seller (a "Back-Up Supplier"). Such right
shall continue until Seller notifies Buyer that Seller is able to supply all
Licensed Products required by Buyer as provided herein, in which case Buyer
shall recommence sourcing Licensed Products from Seller once any outstanding
orders from a Back-Up Supplier have been satisfied (provided that Buyer shall
not at any time enter into binding commitments for the purchase of quantities of
Licensed Products from any Back-Up Supplier exceeding Buyer's requirements for
Licensed Products during the three-month period commencing with the date of the
latest such commitment). Seller shall be entitled to receive a royalty in an
amount equal to the sum of [***] and (ii) [***] of such Licensed Product sales;
but only to the extent that Buyer's cost of the Licensed Product in finished,
packaged, labelled and quality controlled form ready for resale to the ultimate
customer plus the royalties hereinabove established shall not exceed the [***].
Buyer may elect to act as Back-Up Supplier or, at its election, have a third
party supplier of Buyer's choice (and reasonably acceptable to Seller) act as
Back-Up Supplier. Seller shall cooperate fully with Buyer and any separate
Back-Up Supplier, and shall use commercially reasonable best efforts to enable
the Back-Up Supplier to qualify and validate the Back-Up Supplier's facilities
and to manufacture and package Licensed Products. Seller shall give the Back-Up
Supplier prompt and unrestricted access to, or, if requested, Seller shall
immediately provide to the Back-Up Supplier, all technical information necessary
for the Back-Up Supplier to manufacture Licensed Products during the period
permitted hereby. Any disclosure or use of technical information will be subject
to the confidentiality restrictions set forth in Article 6 of the Sublicense
Agreement. The Back-Up Supplier shall have the right to observe the operation of
any laboratory and manufacturing and/or packaging facility of Seller (subject to
Buyer obligations of confidentiality to third parties), and to have a reasonable
number of employees or other representatives of Seller visit the Back-Up
Suppliers' facilities, at Buyer's option and in accordance with a mutually
agreed timetable, to demonstrate and explain any of the technical information
and the manufacturing and packaging processes for the

Licensed Products. Seller shall reasonably cooperate with Buyer and Back-Up
Supplier to obtain any regulatory approval in the Licensed Territory as may be
required for the manufacture of Licensed Products by the Back-Up Supplier.

                  Section 3.5.  Allocation in the Event of Shortage.

                  If for any reason Seller experiences a shortage of materials
required to manufacture Licensed Products and Seller is therefore unable to
supply Buyer with the full quantity of Licensed Products ordered by it and
accepted by Seller, Buyer shall be entitled to receive that quantity of Licensed
Products which bears the same proportion to the total quantity of available
Licensed Products as the quantity of Licensed Products purchased by Buyer from
Seller in the 12 months preceding the supply shortage (or a shorter period if
Buyer has started purchasing Licensed Products less than 12 months before the
shortage occurs) bears to all purchases of orders from Seller from all customers
(including Buyer) for Licensed Products during such period.

                  as set forth in this Agreement, there are no preemptive rights
                  or other rights to subscribe for or to purchase, or any

                  Common Stock, pursuant to Seller's Certificate of
                  Incorporation or Bylaws or any agreement or other instrument
                  to which Seller is a party. The sale of the Shares as
                  contemplated in this Agreement does not give rise to any
                  rights, other than those which have been waived for or

                  (other than as provided in Article 4 of this Agreement). The

                  including any such



                                      -3-

                  agreement, arrangement, commitment or understanding
                  restricting or otherwise relating to the voting, dividend

         Section 2.05. SEC Filings. Seller has duly and timely filed with the
SEC all reports (the "Reports") required by the Securities Exchange Act of 1934
(the "1934 Act"). None of the Reports contained, at the time they were filed,
any untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary to make the statements made therein
in light of the circumstances under which they were made, not misleading. The
financial statements (including the related notes) of Seller included in the
Reports present fairly the financial position of Seller as of the dates
indicated and its results of operations for the period specified therein. All
such financial statements have been prepared in accordance with United States
generally accepted accounting principles on a basis consistently applied. Seller
will timely make in the future all required filings with the SEC.

         Section 2.06. Absence of Certain Changes. Since December 31, 1998,
there has been no material adverse change in the business, properties,
operations, condition (financial or otherwise), or results of operations of
Seller, except as disclosed in Seller's SEC filings and except for uses of cash
in the course of Seller's business and corresponding decreases in stockholders'
equity.

         Section 2.07. No Conflicts. Seller is not in violation of its
Certificate of Incorporation or Bylaws or in default in the performance of any
material obligation contained in any material agreement, indenture or other
instrument. The performance by Seller of its obligations under this Agreement
and the consummation of the transactions herein contemplated will not conflict
with or result in a breach of the Certificate of Incorporation or Bylaws of
Seller, or any material agreement, indenture or other instrument to which Seller
is a party or by which it is bound, or any law, rule, administrative regulation
or decree of any court or governmental authority having jurisdiction over Seller
or its properties, or result in the creation or imposition of any material lien,
charge, claim or encumbrance upon any property or asset of Seller under any such
agreement, indenture or other instrument. Except as required by the Act and
applicable state securities or blue sky laws, no consent, approval,
authorization or order of any court or governmental authority is required in
connection with the consummation of the transactions contemplated by this
Agreement. The rights granted to the Purchaser hereunder do not in any way
conflict with and do not violate any rights granted to the other holders of
Seller's securities or debt instruments.

         Section 2.08. Properties. Except as otherwise stated in the Reports,
(A) Seller has good marketable title (in fee simple, in the case of real
property), free and clear of all liens and encumbrances, to all of the material
real and personal property described in the Report as being owned by it, except
for any liens and encumbrances which are not material in the aggregate and do
not materially interfere with the conduct of the business of Seller, and (B) has
valid leases to the material real property described in the Report as under
lease to it with such exceptions as do not materially interfere with the conduct
of the business of Seller.

         Section 2.09. Disputes. Except as set forth in the Reports, there are
no actions, suits or proceedings pending before or by any court or governmental
agency or authority, or any arbitrator, which seek to restrain or prohibit the
consummation of the transactions contemplated hereby or which might reasonably
be expected to result in any material adverse change in the condition (financial
or other), business or results of operations of Seller and, to Seller's
knowledge, no such action, suit or proceeding is being threatened.

         Section 2.10. Compliance with Laws. Seller is not in violation of any
law, ordinance, governmental rule or regulation or court degree to which it may
be subject and Seller has not failed to obtain any license, permit, franchise or
other governmental authorization necessary to the ownership of its property or
to the conduct of its business as conducted on the date hereof, which violation
or failure to obtain is likely to have a material adverse effect on the
condition (financial or other), business or results of operations of Seller.

other similar laws affecting the enforcement of creditors' rights generally. No

                           (b) The Purchaser has received and carefully reviewed
                  copies of (i) Seller's Annual Report on Form 10-KSB for the
                  year ended December 31, 1998 (including without limitation the
                  section thereof entitled "Important Considerations Regarding
                  Forward-Looking Statements"), (ii) Seller's Quarterly Report
                  on Form 10-QSB for the quarter ended June 30, 1999 and (iii)
                  all current reports on Form 8-K filed since the date of the
                  Seller's Form 10-QSB for the quarter ended June 30, 1999.
                  Purchaser has also been afforded the opportunity to ask
                  questions of and receive answers from duly authorized officers
                  or other representatives of Seller and has received any
                  additional information regarding Seller which Purchaser has
                  requested.

                           (c) The Purchaser's consent to this Agreement was not
                  obtained by means of any form of general solicitation or
                  general advertising, and in connection therewith Purchaser did
                  not: (A) receive or review any advertisement, article, notice
                  or other communication published in a newspaper or magazine or
                  similar media or broadcast over television or radio whether
                  closed circuit, or generally available; or (B) attend any
                  seminar meeting or industry investor conference whose
                  attendees were invited by any general solicitation or general
                  advertising.

                           (d) The Purchaser is an accredited investor within
                  the meaning of Rule 501 under the 1933 Act, and Purchaser was
                  not formed for the purpose of receiving the Shares. The
                  Purchaser, either by reason of Purchaser's business or
                  financial experience or the business or financial experience
                  of Purchaser's purchaser representative (within the meaning of
                  Rule 501 under the 1933 Act), which Purchaser representative,
                  if any, is unaffiliated with and is not compensated by Seller
                  or any affiliate of Seller, directly or indirectly, has the
                  capacity to protect Purchaser's interests in connection with
                  the transactions contemplated by this Agreement.

                           (e) The Purchaser recognizes that its purchase of the
                  securities contemplated herein involves a high degree of risk
                  in that (i) an investment in Seller is highly speculative and
                  (ii) Purchaser could sustain the loss of Purchaser's entire
                  investment.

                  DELIVERED TO THE COMPANY.

The share certificate may also have such additional legends, if any, as may be
required in order to comply with the applicable "blue sky" laws of any
jurisdiction. The Purchaser further agrees to the issuance by Seller to its
transfer agent of stop transfer instructions with respect to any sale or other
transfer of the Shares by Purchaser absent registration under the Securities Act
or the establishment by Purchaser of an exemption therefrom in accordance with
this Agreement.

         Section 4.02. Transfer Restrictions. Purchaser acknowledges that:


                      (a) the Shares have not been and are not being
             registered under the provisions of the 1933 Act and are not
             intended to be registered under the Securities Act and are
             intended to be exempt from the registration requirements of

             transfer is registered under the 1933 Act or (B) Purchaser
             shall have delivered to Seller an opinion of counsel,
             reasonably satisfactory in form, scope and substance to
             Seller, to the effect that the Shares to be sold or
             transferred may be sold or transferred pursuant to an
             exemption from such registration;

                      (c) any sale of the Shares made in reliance on Rule
             144 promulgated

             under the 1933 Act may be made only in accordance with the terms of
             said Rule and further, if said Rule is not applicable, any resale
             of such Shares under circumstances in which the seller, or the
             person through whom the sale is made, may be deemed to be an
             underwriter, as that term is used in the 1933 Act, may require
             compliance with some other exemption under the 1933 Act or the
             rules and regulations of the SEC thereunder; and

                      (d) neither Seller nor any other person is under any
             obligation to register the Shares under the 1933 Act or,

<PAGE>


party to appoint its designated arbitrator within the next ten days, and the
