                                 COMPANY SUMMARY

     We are a  development  stage  pharmaceutical  company  that is  focused  on
developing  compounds  intended  for  neonatal  use in  critical  care  hospital
settings. We are also developing our lead product candidate for the treatment of
acute  respiratory  distress  syndrome and acute lung injury.  Our two lead drug
candidates are directed towards  respiratory  indications.  We may seek to enter
into  collaborations  with corporate partners for manufacturing and marketing of
such drugs.

     Our  lead  product  is  Surfaxin(R),  a  peptide-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 during expiration of air and raise
it during inspiration of air to prevent the collapse of alveoli.  If there is an
insufficient  quantity of  surfactants,  the lungs do not absorb enough  oxygen.
Replacement  surfactant  are currently  approved  only for treating  respiratory
distress syndrome ("RDS") in premature infants.  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 syndrom ("MAS"),  typically suffer
from  insufficient  surfactant  that  can  lead  to a  life-threatening  loss of
pulmonary  function.  In  addition,  patients  with acute  respiratory  distress
syndrome and acute lung injury  ("ARDS/ALI")  typically  suffer from  surfactant
deficiency as well.  ARDS/ALI can result from  pneumonia,  aspiration of gastric
contents, trauma, smoke inhalation, head injury, and a variety of other events.

     We are also developing  SuperVent(TM) as a stable,  aerosolized therapy for
airway  diseases such as cystic fibrosis  ("CF") and chronic  bronchitis.  These
conditions are characterized by inflammation,  injurious oxidation and excessive
sputum.  CF  is  a  progressive,   lethal  respiratory   disease  that  afflicts
approximately  23,000  patients in the United States and a comparable  number in
Europe.  It is the most common  lethal  genetic  disease  among  Caucasians.  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 adheres to airway walls.
This can lead to gradual destruction of the lungs of CF patients.  The inability
to clear  mucus  from the  lungs can lead to  blockage  of the  airways  usually
beginning in the smaller  airways and alveoli.  A new therapy that minimizes the
complications  of CF could have a major impact on the length and quality of life
of its patients.

     We are conducting  clinical  trials of Surfaxin(R) for treatment of MAS and
ARDS/ALI and SuperVent(TM) for treatment of CF.

     Discovery  Laboratories was incorporated in Delaware on November 6, 1992 as
Ansan,  Inc.  On November  25,  1997,  Discovery  Laboratories,  Inc.,  a former
Delaware  corporation  ("Old  Discovery"),  was merged  with and into  Discovery
Laboratories, then known as Ansan. Pursuant to this merger in 1997, our name was
changed to Discovery

                                  RISK FACTORS

     Investing  in our common stock  involves a high degree of risk.  You should
consider  carefully  the following  risk factors  together with all of the other
information  included or incorporated by reference in this prospectus before you
decide to  purchase  shares of our  common  stock.  The risks and  uncertainties
described below are not the only ones facing our company.  Additional  risks and
uncertainties not presently known to us or that we currently deem immaterial may
also impair our business operations.

     If any of the following  risks  actually  occur,  our  business,  financial
condition and results of operations could be materially and adversely  affected.
In this event, the trading price of our common stock could decline and you could
lose part or all of your investment.

We are a Development Stage Company.

     We are a  development  stage  company.  Therefore,  you must evaluate us in
light of the  uncertainties  and  complexities  present in a  development  stage
pharmaceutical   company.  Our  product  candidates  are  in  the  research  and
development  stage  and,  accordingly,  we have not begun to market or  generate
revenues from the commercialization of any of these products. Our products under
development  will  require  significant   time-consuming  and  costly  research,
development,  preclinical  studies,  clinical testing,  regulatory  approval and
significant additional investment prior to their  commercialization.  We may not
be able to develop and commercialize our products. We cannot assure you that our
products under development,  if successfully developed, will generate sufficient
or sustainable revenues to enable us to be profitable.

Our Future Profitability is Uncertain.

     As a  development  stage  company  engaged in  conducting  development  and
clinical testing activities,  we expect to generate significant operating losses
for the foreseeable future. We are not currently generating any product revenues
and we expected that we will not generate  significant  product revenues for the
foreseeable  future,  if at all.  We  expect  to  incur  significant  increasing
operating losses over the next several years. To achieve profitable  operations,
we, either alone or with others, must successfully develop and obtain regulatory
approval for marketing our products. We cannot assure you that we will:

     --   enter into potentially necessary collaborative arrangements with third
          parties;

     --   successfully complete preclinical or clinical trials;

     --   obtain required regulatory approvals;

     --   successfully develop, manufacture and market product candidates; or

     --   generate additional revenues or profitability.

     If we fail to  achieve  any of the above  goals,  our  business,  financial
condition and results of operations will be materially adversely affected.

We Do Not Have Any Developed or Approved Products and the Successful Development
of Our Products is Uncertain.

     Our development of products is subject to the risks of failure  inherent in
the  development  of new  pharmaceutical  products  based on  innovative  or new
technologies.  We will be subject to the  problems,  delays,  uncertainties  and
complications  encountered  in connection  with  development  stage life science
businesses.  Some of  these  unanticipated  problems  may  include  development,
regulatory, manufacturing, distribution and marketing difficulties that we may

864725.3

                                       5
<PAGE>




not have the financial or technical  resources to resolve.  In  particular,  our
proposed  drug products  could cause adverse  effects that may prevent them from
being  marketed,  regardless  of  their  efficacy.  Although  our  initial  drug
candidates have been the subject of certain clinical trials, it is possible that
previously  undetected adverse effects may occur during the clinical trials that
will be required  to meet the  requirements  of the United  States Food and Drug
Administration (the "FDA"). We cannot assure you that:

     --   our research and development activities will be successful;

     --   our products under development will prove to be safe and effective;

     --   any of our preclinical or clinical development work will be completed;

     --   we will ever achieve any of our new drug application filing objectives
          with the FDA;

     --   FDA approval will be attained for any of our products;

     --   our proposed products will be commercially viable or successfully
          marketed;

     --   we will protect our proprietary technology through domestic and
          international patents;

     --   third parties do not hold proprietary rights that will preclude us
          from marketing our products, if any; or

     --   if the products under development are approved by the FDA, we will
          ever achieve significant revenues or profitable operations.

     If a significant  portion of our development  efforts are not  successfully
completed,  required  regulatory  approvals  are not  obtained,  or any approved
products are not commercially successful, our business,  financial condition and
results of operations will be materially adversely affected.

We Will Need to Raise Additional Capital That May Not be Available.

     We will need  substantial  additional  funding to conduct our  research and
product  development  activities  and, if  approved by the FDA or  corresponding
foreign regulatory authorities, to manufacture and market the products currently
under development and any other products that we may develop in the future.  Our
existing  working capital will not be sufficient to meet our needs. We intend to
seek to raise  further funds through  collaborative  ventures  entered into with
potential corporate partners and additional debt or equity financings. We cannot
provide  assurance  that  any such  arrangements  can be  obtained.  We have not
entered into arrangements to obtain any additional financing. We may not be able
to obtain  adequate  additional  financing on acceptable  terms,  if at all. Any
additional  financing could not result in significant  dilution of stockholders'
interests.  If we  fail to  enter  into  collaborative  ventures  or to  receive
additional funding, our research and development  operations would be materially
adversely  affected.  Furthermore,  we could  ultimately  cease to  qualify  for
listing of our securities on the Nasdaq SmallCap  Market.  See page 11 "Possible
Delisting  From Nasdaq  SmallCap  Market;  Market  Illiquidity."  If  additional
financing  is not  available,  we  will  be  required  to  modify  our  business
development plans or reduce or cease certain or all of our operations.

We Are Subject to Extensive Government Regulations and We May Not Be Able to
Obtain Regulatory Approvals.

     The testing, manufacture,  distribution,  advertising and marketing of drug
products  are subject to  extensive  and  rigorous  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 an
extensive  regulatory  approval  process  required by the FDA and by  comparable
agencies in other countries. This process, which includes

864725.3

                                       6
<PAGE>


preclinical  studies  and  clinical  trials of each  pharmaceutical  compound to
establish its safety and  effectiveness  and  confirmation  by the FDA that good
laboratory,  clinical and manufacturing practices were maintained during testing
and manufacturing,  is lengthy, expensive and uncertain.  Generally, in order to
gain FDA approval,  a company 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  investigational  new drug  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
more to complete.

     The  testing  and  approval  processes  take  many  years and  require  the
expenditure of substantial resources. We may not be able to obtain the requisite
approvals for our products on a timely basis, if at all. Any required approvals,
once  obtained,  may be  withdrawn.  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,  we may be restricted or
delayed  in the  marketing  of a  product,  forced to make  product  recalls  or
seizures or may be subject to other sanctions such as fines, injunctions,  civil
penalties or criminal prosecutions.  For marketing outside the United States, we
also will be subject to foreign regulatory requirements governing human clinical
trials and marketing approval for pharmaceutical  products. None of our products
under  development  has been  approved  for  marketing  in the United  States or
elsewhere.  We may not be  able to  obtain  regulatory  approval  for any of our
products  under  development.  If  we  fail  to  obtain  requisite  governmental
approvals or fail to obtain  approvals of the scope  requested of our  business,
financial  condition  and results of  operations  will be  materially  adversely
affected.

We Depend on Others for the Development, Clinical Testing, Manufacturing and
Marketing of Our Pharmaceutical Products.

     Our  strategy  for  the  development,   clinical  testing,   manufacturing,
marketing  and  commercialization  of our products has  depended  upon,  and may
continue to depend  upon,  the  formation  of  collaborative  arrangements  with
pharmaceutical companies. We have not yet entered into any of these arrangements
or agreements to date. Our success will depend upon obtaining such partners.  In
addition,  if we obtain such  partners,  we will depend on their  expertise  and
their dedication of sufficient resources to develop and commercialize certain of
our proposed products. We may in the future grant to our collaborative partners,
if any, rights to license and commercialize  pharmaceutical  products  developed
under these collaborative  agreements.  Those rights would limit our flexibility
in considering  alternatives for the  commercialization of such products. We may
not be successful in establishing any collaborative  arrangements.  In addition,
if we  establish  arrangements,  our future  partners may not be  successful  in
developing and  commercializing  products.  If we fail to  successfully  develop
these  relationships  or if  our  collaborative  partners  fail  to  develop  or
commercialize  successfully  any  of  our  products,  our  business,   financial
condition and results of operations may be materially adversely affected.

We Face Technological Uncertainty and Obsolescence.

     The  market  for   biotechnology   is  characterized  by  rapidly  changing
technology and evolving industry  standards.  Our products under development are
intended to treat diseases for which other technologies and proposed  treatments
are rapidly  developing.  The results of our  research  and product  development
efforts may be rendered  obsolete by research  efforts of others,  including the
efforts and  activities of  governments,  major  research  facilities  and large
multinational corporations with greater research and development, manufacturing,
marketing, financial,  technological,  personal and managerial resources than we
have.

Our Success Depends on Patents, Licenses and the Protection of Our Propriety
Rights and We Face the Risk of Loss of our Rights to Proprietary Technology.

     We seek  proprietary  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 protection for new technologies,
products and processes.  Our success will depend in part on our ability and that
of our licensors to:


864725.3

                                       7
<PAGE>


     --   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, there has emerged no
consistent  policy at the United  States  Patent and  Trademark  Office  ("PTO")
regarding the breadth of claims allowed in  biotechnology  patents or the degree
of protection afforded under such patents.

     Various  United  States  and  foreign   patents   applications   (including
international  applications filed under the Patent Cooperation Treaty) have been
filed with respect to the products and  technologies  under our  development and
patents have been issued with respect to our  products and  technologies.  These
patents and patent  applications  have been  licensed to us. Our pending  patent
applications,  those we may file in the  future,  or those we may  license  from
third parties,  may not result in patents being issued.  Also, patent rights may
not be sufficiently  broad enough to provide us with  proprietary  protection or
competitive   advantages   against   competitors   with  similar   products  and
technologies. Furthermore, patents, if issued, may be challenged, invalidated or
circumvented.  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 it were to be determined
that low  concentrations of tyloxapol are as effective as higher  concentrations
of tyloxapol in treating the indications for which we are seeking to develop our
SuperVent(TM) product.

     Our commercial success also depends significantly on our ability to operate
without  infringing the patents or violating the proprietary rights of others. A
United   States  patent   application   is   maintained   under   conditions  of
confidentiality  while the application is pending.  Accordingly,  we will not be
able to determine  which  inventions are claimed in pending patent  applications
filed by third  parties.  Litigation  may be  necessary to defend or enforce our
patent  and  license  rights  or to  determine  the scope  and  validity  of the
proprietary  rights of others.  Defense and  enforcement of patent claims can be
expensive and time-consuming. Thus, even in those instances in which the outcome
is favorable to us, such  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 may not be available
from third  parties.  We may be required to alter our  products or  processes or
cease  altogether  any related  research and  development  activities or product
sales.  These  outcomes  could have a material  adverse  effect on our business,
financial condition and results of operations.

     We depend on  licensing  arrangements  to maintain  rights to our  products
under development,  and we will be required to make certain payments and satisfy
certain   performance   obligations  in  order  to  maintain   those   licensing
arrangements.  Pursuant to our licensing agreements,  we are responsible for the
cost of filing  and  prosecuting  patent  applications  and  maintaining  issued
patents.  If we do not meet our  obligations  under our license  agreements in a
timely  manner,  we could lose the rights to our  proprietary  technology.  This
would have a material  adverse effect on our business,  financial  condition and
results of operations.

     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  such   employees'   ideas,
developments, discoveries and inventions while so employed. In addition, we seek
to  obtain  such  agreements  from  our   consultants,   advisors  and  research
collaborators.  To the extent that  consultants,  key  employees  or other third
parties apply technological  information  independently  developed by them or by
others to any of our proposed projects, disputes may arise as to the proprietary
rights to such information  which may not be resolved in our favor. In addition,
we will rely on trade  secrets  and  proprietary  know-how  that we will seek to
protect in part by confidentiality  agreements with its employees,  consultants,
advisors or others. We cannot assure you that:


864725.3

                                       8
<PAGE>


     --   these agreements will not be breached;

     --   we would obtain adequate remedies for any such breach; or

     --   our trade secrets or proprietary know-how will not otherwise become
          known or be independently developed by competitors.

We Depend on Third Party Suppliers and Manufacturers.

     We  currently  own  most  of  the  manufacturing   equipment  necessary  to
manufacture  Surfaxin(R).  However,  we will  be  required  to  rely on  outside
manufacturers,  including Taylor  Pharmaceuticals,  Inc., to produce appropriate
clinical grade material  which meets  standards for use in clinical  studies for
certain of our products.

     Our  outside  manufacturers  may not perform as agreed or may not remain in
the contract  manufacturing business for the time required by us to successfully
produce and market our product candidates.  If one of our outside  manufacturers
fails to deliver the required  quantities of our product candidates for clinical
use on a timely basis and at commercially reasonable prices, and we fail to find
a replacement  manufacturer or develop our own manufacturing  capabilities,  our
business,  financial  condition  and results of  operations  will be  materially
adversely affected.

     In  addition,  our  third-party  manufacturers  are  required  to  register
manufacturing  facilities with the FDA and foreign regulatory  authorities.  The
facilities will then be subject to inspections  confirming  compliance with good
manufacturing  practice  requirements  established with the FDA or corresponding
foreign  regulations.  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,  our  business,  financial
condition and results of operations will be materially adversely affected.

We Do Not Have Marketing and Sales Experience.

     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 be
dependent  on  entering  into  arrangements  with  corporate  partners  or other
entities for the marketing and sale of our products. We may not be successful in
entering into any  satisfactory  third-party  arrangements for the marketing and
sale of our products. In addition, we may not successfully develop marketing and
sales experience and personnel or we may not have sufficient resources to do so.
If we fail to establish  successful  marketing and sales capabilities or fail to
enter into  successful  distribution,  marketing and selling  arrangements  with
third parties for our anticipated  products,  our business,  financial condition
and results of operations will be materially adversely affected.


We Depend Upon Key Employees and Consultants in a Competitive Market for Skilled
Personnel.

     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.  The loss of any of
these persons' services would have a material adverse effect on our business.

     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.  We may not be able to continue to
attract and retain personnel necessary for the development of our business.

We Face Intense Competition.

     We are engaged in a highly competitive industry.  Competition from numerous
existing  companies  and  potential  new  entities  is intense  and  expected to
increase. Many of these companies have substantially greater research and


864725.3


                                       9
<PAGE>



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.

     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 be competing  against  companies with greater
marketing  and  manufacturing  capabilities,  areas in  which,  as yet,  we have
limited or no experience.  In addition,  developments  by competitors may render
our product candidates  obsolete or competitive.  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 which may be directly  competitive  with the
technologies to be developed by us. These institutions will also compete with us
in  recruiting  highly  qualified  scientific  personnel.  It is  expected  that
therapeutic  developments in the areas in which we will be active may occur at a
rapid rate and that  competition  will  intensify  as advances in this field are
made.  Accordingly,  we will be  required  to  continue  to  devote  substantial
resources and efforts to research and development activities.

If We Become Subject to Product Liability Claims, It May Result in Reduced
Demand for Our Products or Damages That Exceed Our Insurance Coverage.

     If we  successfully  develop any  products,  the  marketing and use of such
products, through third party arrangements or otherwise,  whether for commercial
applications or during clinical trials,  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.  We presently  carry  product  liability  insurance
relating to our clinical  trials of  SuperVent(TM)  and our  clinical  trials of
Surfaxin(R) in treating ARDS/ALI and MAS. However, such insurance coverage might
not be  sufficient to fully cover any  potential  claims.  We may be required 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, such insurance can
be expensive and difficult to obtain.  We cannot provide assurance that adequate
insurance will be available in the future at an acceptable  cost, if at all. Any
product  liability  claim,  even  one that was not in  excess  of our  insurance
coverage or one that was  ultimately  determined to be  meritless,  could have a
material  adverse  effect on our  business,  financial  condition and results of
operations.

We Face Uncertainty Over Reimbursement and Health Care Reform.

     The  levels  of  revenues  and  profitability  of   pharmaceutical   and/or
biotechnology  products and companies may be affected by efforts of governmental
and third  party  payers to contain or reduce the costs of health  care  through
various means. For example, in certain 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 have a
material adverse effect on our business.


864725.3


                                       10
<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.  Adequate third party  reimbursement may
not be available 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,  we may not
be able to sell our products on a competitive  basis. If we are not able to sell
our products on a  competitive  basis,  our  business,  financial  condition and
results of operations will be materially adversely affected.

Directors, Executive Officers, Principal Stockholders and Affiliated Entities
Own a Significant Percentage of Our Capital Stock.

     As of  August  13,  1999,  our  directors,  executive  officers,  principal
stockholders  and  affiliated  entities  beneficially  own,  in  the  aggregate,
approximately 23% of our outstanding voting securities,  assuming  conversion of
convertible  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.  Such a concentration
of ownership  may have the effect of delaying or preventing a change in control,
including  transactions in which  stockholders might otherwise recover a premium
for their shares over their current market prices.

We Face the Possibility of Being Delisted from the Nasdaq SmallCap Market.

     To meet the current  Nasdaq  listing  requirements  for our  securities  to
continue to be listed on the Nasdaq  SmallCap  Market,  we will have to maintain
(a) (1) at least $2 million in net  tangible  assets,  (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. In addition,  our common stock will have
to be held by at least 300  holders  and will  have to have at least two  active
market  makers.  For purposes of  determining  compliance  with the public float
requirement,  shares of stock  held by  officers,  directors  and 10% or greater
stockholders are excluded.

     If we are unable to satisfy the NASD's  listing  maintenance  requirements,
our securities may be delisted from the Nasdaq SmallCap  Market.  In such event,
trading,  if  any,  in our  securities  would  thereafter  be  conducted  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, the liquidity of our securities could be impaired, not only in the
number of securities  which could be bought and sold, but also through 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 than might otherwise
be attained.

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

     If our securities were to be delisted from the Nasdaq SmallCap Market, they
could  become  subject to Rule  15g-9  under the  Exchange  Act,  which  imposes
additional  sales  practice  requirements  on  broker-dealers  which  sell  such
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  covered  by  this  rule,  a  broker-dealer  must  make  a  special
suitability  determination  for the purchaser and have received 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 the  securities
acquired hereby in the secondary market.

     The Commission has adopted  regulations  which define a "penny stock" to be
an equity security that has a market price (as therein  defined) less than $5.00
per share or with an  exercise  price of less than $5.00 per  share,  subject to
certain exceptions.  For any transaction involving a penny stock, unless exempt,
the rules require delivery,

864725.3


                                       11
<PAGE>




prior to any transaction in a penny stock, of a disclosure  schedule prepared by
the Commission  relating to the penny stock market.  Disclosure is also required
to be  made  about  commissions  payable  to  both  the  broker-dealer  and  the
registered  representative and current  quotations for the securities.  Finally,
monthly  statements are required to be sent 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 our  securities
continue to be listed on the Nasdaq  SmallCap  Market and have certain price and
volume  information  provided on a current and continuing  basis or meet certain
minimum net tangible assets or average revenue criteria.  Our securities may not
qualify  for  exemption  from  these  restrictions.  In any  event,  even if our
securities continue to be exempt from such restrictions, we would remain subject
to  Section  15(b)(6)  of the  Exchange  Act,  which  gives the  Commission  the
authority  to  prohibit  any person that is engaged in  unlawful  conduct  while
participating  in a  distribution  of a  penny  stock  from  associating  with a
broker-dealer  or  participating  in a  distribution  of a penny  stock,  if the
Commission finds that such a restriction would be in the public interest. If our
securities  were subject to the existing or proposed rules on penny stocks,  the
market liquidity for our securities could be severely adversely affected.

A Substantial Number of Our Securities are Eligible for Future Sale.

     As of June 1, 1999, we had outstanding  approximately  (i) 6,568,300 shares
of common stock;  (ii) 1,678,755 shares of Series B preferred stock  convertible
into  5,226,392  shares of common  stock;  (iii)  735,833  Class A  warrants  to
purchase an  aggregate  of 735,833  shares of common  stock and 735,833  Class B
warrants to purchase an additional  735,833 shares of common stock; (iv) 498,333
Class B warrants to purchase 498,333 shares of common stock; (v) 531,915 Class C
warrants to purchase 531,915 shares of common stock; (vi) a unit purchase option
to purchase an aggregate of 173,333 shares of common stock, assuming exercise of
the underlying warrants;  (vii) outstanding options to purchase 2,263,093 shares
of  common  stock;  (viii)  warrants  to  purchase  220,026  shares  of Series B
preferred stock, and (ix) warrants to purchase 75,087 shares of common stock. In
addition,  2,039 shares of Series C preferred stock,  which are convertible into
additional  shares of common  stock  under  certain  circumstances  based on the
liquidation  value of the Series C preferred  stock and the market  price of the
common stock, are presently outstanding.  The shares of Series C preferred stock
would be convertible into  approximately  1,775,821 shares of common stock based
on the market price of the common stock as of June 1, 1999.

     Our stock options and warrants are likely to be exercised,  if at all, 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.  Any
such  exercise or the  possibility  of such  exercise  may impede our efforts to
obtain additional  financing  through the sale of additional  securities or make
such financing more costly.

     No prediction can be made as to the effect,  if any, that the  availability
of these  shares  for sale will have on the market  price of our  common  stock.
Nevertheless, because substantial amounts of our common stock may be sold in the
public market,  subject,  in some cases,  to compliance  with Rule 144 under the
Securities  Act,  the market price of our common stock could drop as a result of
sales of these  securities or the  perception  that such sales may occur.  These
factors could also make it more  difficult for us to raise funds through  future
offerings of securities.

We are Subject to Antitakeover Provisions of our Certificate of Incorporation
and Delaware Law.

     Certain provisions of our Certificate of Incorporation,  as amended,  allow
us to issue shares of preferred  stock without any vote or further action by our
shareholders.  In particular,  our Certificate of Incorporation provides for the
issuance of up to 5,000,000 shares of preferred stock, of which 1,714,425 shares
are  outstanding  and of which 220,026 shares are reserved for issuance upon the
exercise  of  warrants.  Our Board of  Directors  has the  authority  to fix and
determine the relative  rights and preferences of preferred  shares,  as well as
the authority to issue such shares,  without further stockholder  approval. As a
result,  our Board of  Directors  could  authorize  the  issuance of a series of
preferred  stock which would grant to holders the preferred  right to our assets
upon  liquidation,  the right to receive dividend coupons before dividends would
be declared to holders of common stock, and the right to the


864725.3


                                       12
<PAGE>


redemption of such shares,  together with a premium,  prior to the redemption of
our  common  stock.  Holders  of common  stock  have no  redemption  rights.  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 subject to certain  provisions  of Delaware law which 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 which  prohibits  a  Delaware  corporation  from  engaging  in any  business
combination  with any interested  stockholder for a period of three years unless
certain  conditions  are met.  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 such  entity or  person.  The  possible
issuance  of  preferred  stock  and  Delaware  law  could  have  the  effect  of
discouraging  others  from making  tender  offers for our  securities  and, 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.

We do Not Intend to Pay Dividends.

     We  intend to  retain  any  future  earnings  to  finance  the  growth  and
development  of our  business  and we do not plan to pay cash  dividends  in the
foreseeable future.

Our Business Could be Affected by the Year 2000 Issue.

     The Year 2000 Issue is the result of computer  programs being written using
two digits rather than four to define the applicable year. Any computer programs
or hardware that have date-sensitive  software or embedded chips may recognize a
date using "00" as the year 1900 rather than the year 2000.

     In terms of our internal operations,  we do not use equipment with embedded
chip  technology  that is date  sensitive.  We  expect  that the  systems  to be
affected  by the Year 2000 date  change  include the  database,  networking  and
accounting  software  licensed  by us. We expect  to incur  out-of-pocket  costs
related to making inquiries of, and receiving  confirmations from, third parties
of no more than $10,000.

     If our computer  systems or the computer  systems of any of our  suppliers,
customers or other third parties are not Year 2000 compliant or if those systems
are unable to recover from system  interruptions  which may result from the Year
2000 date change, our business could be materially adversely affected.


                                 USE OF PROCEEDS

     We will not  receive  any  proceeds  from the sales of common  stock by the
selling stockholders pursuant to this prospectus.

                              PLAN OF DISTRIBUTION

     The  shares of common  stock  covered by this  prospectus  are owned by the
selling stockholders. As used in the rest of this section of the prospectus, the
term "Selling  Stockholders"  includes the named selling stockholders and any of
their  pledgees,  donees,  transferees or other  successors in interest  selling
shares  received  from a  named  selling  stockholder  after  the  date  of this
prospectus.  The shares of common stock covered by this  prospectus are referred
to in this section as the "Shares." The Selling Stockholders may offer and sell,
from time to time, some or all of the Shares.  We have registered the Shares for
sale by the Selling  Stockholders so that the Shares will be freely tradeable by
them.  Registration  of the  Shares  does not  mean,  however,  that the  Shares
necessarily  will be offered or sold.  We will not receive any proceeds from any
offering or sale by the  selling  stockholders  of the  Shares.  We will pay all
costs,  expenses and fees in connection with the registration of the Shares. The
Selling  Stockholders  will pay all brokerage  commissions  and similar  selling
expenses, if any, attributable to the sale of the Shares.

     The Selling  Stockholders  will act independently of us in making decisions
with respect to the timing, manner and size of each sale. The Shares may be sold
by or for  the  account  of the  Selling  Stockholders  from  time  to  time  in
transactions on the Nasdaq SmallCap  Market,  the  over-the-counter  market,  or
otherwise.  These sales may be at fixed prices or prices that may be changed, at
market  prices  prevailing  at the  time of  sale,  at  prices  related  to such
prevailing  market  prices or at  negotiated  prices.  The Shares may be sold by
means of one or more of the following  methods:  (a) in a block trade in which a
broker-dealer  will  attempt to sell a block of Shares as agent but may position
and resell a portion of the block as principal to  facilitate  the  transaction;
(b) purchases by a broker-dealer  as principal and resale by that  broker-dealer
for its account  pursuant to this  prospectus;  (c) on markets  where our common
stock is traded or in an exchange  distribution  in accordance with the rules of
the exchange; (d) through broker-dealers, which may act as agents or principals;
(e) directly to one or more  purchasers;  (f) through agents;  (g) in connection
with the loan or pledge of Shares to a broker-dealer, and the sale of the Shares
so loaned or the sale of the Shares so pledged upon a default; (h) in connection
with put or call option transactions,  in hedge transactions,  and in settlement
of other transactions in standardized or over-the-counter  options;  (i) through
short sales of the Shares by the Selling Stockholders or counterparties to those
transactions;   (j)  in  privately  negotiated  transactions;   or  (k)  in  any
combination of the above.  In addition,  any of the Shares that qualify for sale
pursuant to Rule 144 under the  Securities Act may be sold under Rule 144 rather
than pursuant to this prospectus.

     In effecting sales,  brokers or dealers engaged by the Selling Stockholders
may  arrange  for other  brokers or dealers to  participate.  The  broker-dealer
transactions  may  include (a)  purchases  of the Shares by a  broker-dealer  as
principal  and  resales  of the  Shares  by the  broker-dealer  for its  account
pursuant  to  this  prospectus;  (b)  ordinary  brokerage  transactions;  or (c)
transactions in which the broker-dealer solicits purchasers.

     If a material arrangement with any broker, dealer or other agent is entered
into  for the  sale of any  Shares  through  a block  trade,  special  offering,
exchange  distribution,  secondary  distribution,  or a purchase  by a broker or
dealer,  a prospectus  supplement will be filed, if necessary,  pursuant to Rule
424(b) under the  Securities Act disclosing the material terms and conditions of
such arrangement.

     The Selling  Stockholders and any broker-dealers or agents participating in
the  distribution  of the Shares may be deemed to be  "underwriters"  within the
meaning of the  Securities  Act, and any profit on the sale of the Shares by the
Selling  Stockholders and any commissions received by any such broker-dealers or
agents may be deemed to be  underwriting  commissions  under the Securities Act.
The Selling  Stockholders may agree to indemnify any agent or broker-dealer that
participates  in  transactions  involving  sales of the Shares  against  certain
liabilities, including liabilities arising under the Securities Act.

     The Selling  Stockholders  are not  restricted as to the price or prices at
which  they may sell  their  Shares.  Sales of such  Shares  may have an adverse
effect  on  the  market  price  of  the  common  stock.  Moreover,  the  Selling
Stockholders  are not  restricted as to the number of Shares that may be sold at
any time,  and it is possible that a significant  number of Shares could be sold
at the same time,  which may have an adverse  effect on the market  price of the
common stock.

Item 15.  Indemnification of Directors and Officers

     Section 145 of the  Delaware  General  Corporation  law empowers a Delaware
corporation  to  indemnify  any persons who are, or are  threatened  to be made,
parties  to  any  threatened,   pending  or  completed  legal  action,  suit  or
proceedings,  whether civil,  criminal,  administrative or investigative  (other
than action by or in the right of such corporation),  by reason of the fact that
such person was an officer or director of such corporation, or is or was serving
at the request of such corporation as a director,  officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees),  judgments,  fines and amounts paid in settlement actually and
reasonably  incurred  by such person in  connection  with such  action,  suit or
proceeding,  provided that such officer or director acted in good faith and in a
manner he reasonably  believed to be in or not opposed to the corporation's best
interests, and, for criminal proceedings, had no reasonable cause to believe his
conduct was illegal. A Delaware corporation may indemnify officers and directors
in an action by or in the right of the  corporation  under the same  conditions,
except that no  indemnification  is permitted  without judicial  approval if the
officer  or  director  is  adjudged  to be  liable  to  the  corporation  in the
performance  of his duty.  Where an officer or  director  is  successful  on the
merits or  otherwise  in the  defense  of any  action  referred  to  above,  the
corporation  must  indemnify  him against  the  expenses  which such  officer or
director actually and reasonably incurred.

     In accordance with Delaware law, our restated  certificate of incorporation
contains a  provision  to limit the  personal  liability  of our  directors  for
violations of their fiduciary duty as a director. This provision eliminates each
director's  liability to us or our  stockholders for monetary damages except (i)
for any breach of the director's duty of loyalty to us or our stockholders, (ii)
for acts or omissions not in good faith or which involve intentional  misconduct
or a knowing  violation of law, (iii) under Section 174 of the Delaware  General
Corporation  law providing  for  liability of directors for unlawful  payment of
dividends  or  unlawful  stock  purchases  or  redemptions,   or  (iv)  for  any
transaction  from which a director  derived an improper  personal  benefit.  The
effect of this provision is to eliminate the personal liability of directors for
monetary damages for actions involving a breach of their fiduciary duty of care,
including any such actions involving gross negligence.

Item 17.  Undertakings

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

Registration  Statement  shall  be  deemed  to be a new  registration  statement

                            ----------------------------------

Ladies and Gentlemen:

                     We have acted as counsel for Discovery Laboratories, Inc.,
a Delaware  corporation (the  "Company"),  in connection with the preparation of
the  registration  statement  on Form  S-3,  and  any  amendments  thereto  (the
"Registration Statement"),  as filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the  "Securities  Act"), on August
__,  1999,  for the  registration  under the  Securities  Act of up to 5,426,219
shares (the "Shares") of the Company's  common stock, par value $0.001 per share
(the "Common Stock"),  including 2,869,509 shares (the "Outstanding  Shares") of
Common  Stock  which have been  issued  and are  outstanding  and an  additional
2,556,710 shares (the "Warrant  Shares") of Common Stock which are issuable upon
the exercise of certain  warrants (the  "Warrants")  issued by the Company.  The
Shares are to be offered on a delayed or continuous  basis  pursuant to Rule 415
under  the  Securities  Act  by  certain  selling   stockholders  (the  "Selling
Stockholders") named in the Registration  Statement.  Capitalized terms used and
not  defined  in  this  opinion  have  the  meanings  ascribed  to  them  in the
Registration  Statement.  You have  requested  that we furnish our opinion as to
matters hereinafter set forth.

                     In rendering this opinion, we have relied upon, among
other things, our examination of such records of the Company,  including without
limitation,   the  Company's  Restated  Certificate  of  Incorporation  and  the
Company's Bylaws and certificates of its

officers and of public  officials as we have deemed necessary for the purpose of
the opinion expressed below.

                     In addition, we have assumed the genuineness of all
signatures and the  authenticity of all documents  submitted to us as originals,
and the  conformity to original  documents of all  documents  submitted to us as
certified or  photostatic  copies.  As to various  questions of fact material to
this opinion, we have relied, to the extent we deem reasonably appropriate, upon
representations or certificates of officers or directors of the Company and upon
documents,  records and  instruments  furnished  to us by the  Company,  without
independently checking or verifying the accuracy of such documents,  records and
instruments furnished to us by the Company.

                     We are not admitted to the practice of law in any
jurisdiction  but the State of New York, and we do not express any opinion as to
the laws of other  states or  jurisdictions  other than the laws of the State of
New York, the Delaware General Corporation Law and the federal law of the United
States.  No opinion  is  expressed  as to the  effect  that the law of any other
jurisdiction  may have upon the subject matter of the opinion  expressed  herein
under conflicts of law principles, rules and regulations or otherwise.

                     Based on and subject to the foregoing, we are of the
opinion that: (i) the  Outstanding  Shares  offered by the Selling  Stockholders
pursuant to the Registration Statement have been duly and validly authorized and
issued and are fully paid and  nonassessable and (ii) the Warrant Shares offered
by the Selling  Stockholders  pursuant to the  Registration  Statement have been
duly  authorized  for  issuance  pursuant to the Warrants  and,  when issued and
delivered in the manner described in the Warrants, will be validly issued, fully
paid and nonassessable.

                     We consent to the filing of this opinion with the
Securities and Exchange  Commission as an exhibit to the Registration  Statement
and to the use of our name under the caption  "Legal  Matters" in the Prospectus
included therein. In giving this consent, we do not admit that we are within the
category of persons whose consent is required by Section 7 of the Securities Act
of 1933 or the rules and  regulations  promulgated  thereunder by the Securities
and Exchange Commission.

                                          Very truly yours,

INDEPENDENT AUDITORS' CONSENT


We consent to the incorporation by reference in this  Registration  Statement of
