                                  COMMON STOCK
   
This Prospectus relates to the offer (the "Offering") by the securityholders
named herein under the caption "Selling Securityholders" (collectively, the
"Selling Securityholders") for sale to the public of the following securities of
Discovery Laboratories, Inc. ("Discovery"): (i) 2,200,256 shares of Discovery's
common stock, par value $0.001 per share ("Common Stock"); (ii) 8,801,024 shares
of Common Stock issuable upon conversion of currently outstanding shares of
Series A Convertible Preferred Stock, par value $0.001 per share, of Discovery
("Series A Preferred Stock"); (iii) 220,026 shares of Common Stock issuable upon
exercise of certain warrants issued to the placement agent of the Unit Offering
described herein (the "Common Placement Warrants") and (iv) 880,103 shares of
Common Stock issuable upon the conversion of shares of Series A Preferred Stock
issuable upon exercise of certain warrants issued to the placement agent of such
Unit Offering (the "Preferred Placement Warrants" and, together with the Common
Placement Warrants, the "Placement Agent Warrants"). The number of shares of
Common Stock issuable upon conversion of the Series A Preferred Stock is subject
to adjustment in certain events.

Discovery will not receive any proceeds from the sale of shares of Common Stock.
Discovery is not expected to receive any proceeds from the exercise of the
Placement Agent Warrants since the Placement Agent Warrants may be exercised
pursuant to cashless exercise provisions. In the event that the Placement Agent
Warrants are exercised for cash, Discovery intends to use such net cash proceeds
(after estimated offering expenses of the Offering of approximately $300,000)
for general working capital purposes. Proceeds, if any, from the exercise for
cash of all the Placement Agent Warrants, before deduction of estimated expenses
of the Offering, would be approximately $2,475,000. Whether and to what extent
any of the Placement Agent Warrants will be exercised, and whether the Placement
Agent Warrants are exercised for cash or not, cannot be predicted by Discovery.

The Selling Securityholders have advised Discovery that they may sell, directly
or through brokers, all or a portion of the securities offered hereby in
negotiated transactions or in one or more transactions in the market at the
price prevailing at the time of sale. In connection with such sales, the Selling
Securityholders and any participating brokers may be deemed to be "underwriters"
of the Common Stock within the meaning of the Securities Act of 1933. It is
anticipated that usual and customary brokerage fees will be paid by the Selling
Securityholders in all open market transactions. Discovery will pay all other
expenses of this Offering. See "Plan of Distribution."

Discovery will inform the Selling Securityholders that the anti-manipulation
provisions of Regulation M under the Securities Exchange Act of 1934
may apply to the sales of their shares offered hereby. Discovery also will
advise the Selling Securityholders of the requirement for delivery of this
Prospectus in connection with any sale of the shares offered hereby.

Discovery is in the research and development stage, has not had any operating
revenues, and at December 31, 1996, had an accumulated deficit of approximately
$3,254,000. Discovery is continuing to incur losses and expects to incur
significantly increasing additional losses for the foreseeable future.

Prior to the Offering, there has been no public market for the Common Stock and
there can be no assurance that such a market will develop or, if developed, that
it will be sustained. Discovery intends to apply for listing of the Common Stock
on the National Association of Securities Dealers Automated Quotation Small-Cap
Market(R) ("Nasdaq Small-Cap Market") under the symbol "DSCO". The prices of the
Common Stock which may be obtained on any such market are not necessarily
related to Discovery's assets, book value, results of operations or any other
established criteria of value, and should not be regarded as any indication of
future market price of the Common Stock. See "Risk Factors," "Description of
Securities" and "Plan of Distribution."

          THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.
                           SEE "RISK FACTORS", P. 5.
    
  THE COMMON STOCK HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE 
 SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION 
 PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION 
                     TO THE CONTRARY IS A CRIMINAL OFFENSE.

THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE MORE DETAILED INFORMATION AND THE FINANCIAL
STATEMENTS AND NOTES THERETO, INCLUDING, WITHOUT LIMITATION, THE INFORMATION
UNDER "RISK FACTORS," APPEARING ELSEWHERE IN THIS PROSPECTUS OR INCORPORATED
HEREIN BY REFERENCE, AND, ACCORDINGLY, SHOULD BE READ IN CONJUNCTION THEREWITH.
REFERENCES IN THIS PROSPECTUS TO "DISCOVERY" REFER TO DISCOVERY LABORATORIES,
INC., AND REFERENCES TO THE "COMPANY" REFER TO DISCOVERY LABORATORIES, INC. AND
ITS MAJORITY-OWNED SUBSIDIARY, ACUTE THERAPEUTICS, INC. ("ATI"), UNLESS THE
CONTEXT OTHERWISE REQUIRES.

                              COMPANY SUMMARY

The Company is a development stage pharmaceutical company that is focused on
acquiring, developing and commercializing proprietary investigational drugs that
have previously been tested in humans or animals. The Company's strategy is to
conduct preclinical and clinical studies on investigational drugs licensed from
third parties, either on its own or in collaboration with corporate partners.
The Company may also seek to enter into collaborations with corporate partners
for manufacturing and marketing of such drugs. The Company currently has three
licensed investigational drug candidates under development.

SUPERVENT(TM)
   
The Company is developing SuperVent(TM) as a stable aerosolized,
multidimensional therapy for airway diseases characterized by inflammation,
injurious oxidation and excessive sputum. SuperVent's(TM) active compound is
tyloxapol, a compound which has been safely used as an emulsifying agent in drug
formulations by the pharmaceutical industry for over 40 years. Experimental
research has led to the discovery that tyloxapol appears to possess biological
activities beyond its well-recognized emulsification properties. In March 1996,
the Company obtained an exclusive, worldwide license from The
Charlotte-Mecklenburg Hospital Authority ("CMHA") which covers two issued United
States patents, three pending United States patent applications, and
corresponding foreign patent applications, relating to pharmaceutical
preparations containing high concentrations of tyloxapol and to the use of
tyloxapol for the treatment of a variety of respiratory and other diseases
involving inflammation and oxidative damage. The United States Food and Drug
Administration (the "FDA") has granted orphan drug status for the use of
tyloxapol to treat cystic fibrosis ("CF").
    
   
The Company intends to clinically test SuperVent(TM) for the treatment of CF and
chronic bronchitis. CF is a progressive respiratory disease that afflicts
approximately 23,000 patients in the United States and a comparable number of
patients in Europe. It is the most common lethal genetic disease among
Caucasians. The FDA, subject to certain modifications, has approved a
physician-sponsored Investigational New Drug ("IND") application for a proposed
randomized, double-blinded, placebo-controlled Phase I/II clinical trial of
SuperVent(TM) for the treatment of CF. The Company entered into a clinical
research agreement with the University of Utah Health Sciences Center ("UHSC")
and began the aforementioned trial on March 17, 1997, pursuant to such
agreement. Assuming the successful completion of the trial, the Company intends
to commence a multi-center, Phase III clinical trial in CF and to file an
additional IND to commence a Phase II clinical trial for the treatment of
chronic bronchitis. Chronic bronchitis is a disease characterized by
inflammation of the airways leading to coughing and excessive mucus production.
There are an estimated 14,000,000 chronic bronchitis patients in the United
States, many of whom are habitual smokers. If successfully developed and
approved, SuperVent(TM) is intended to be used daily by CF and chronic
bronchitis patients in the home or hospital to preserve pulmonary function and

KL4-Surfactant is a proprietary, synthetic lung surfactant invented at 
The Scripps Research Institute ("Scripps"). The product was exclusively 
licensed to Johnson & Johnson, Inc. ("J&J"), which completed a 
multi-center, Phase II clinical trial of KL4-Surfactant for the treatment of 
infant respiratory distress syndrome ("IRDS"). The Phase II trial demonstrated
safety and efficacy comparable to that of the bovine-derived surfactant, 
Survanta(TM), marketed by Ross Laboratories. In

October 1996, Discovery's majority-owned subsidiary, ATI, acquired the exclusive
worldwide sublicense to the KL4- Surfactant technology.
   
The Company is currently developing KL4-Surfactant for the treatment of meconium
aspiration syndrome ("MAS") and adult respiratory distress syndrome ("ARDS").
The Company may also develop KL4-Surfactant for IRDS. MAS is a disease affecting
approximately 26,000 newborn babies per year in the United States that results
from the release of fetal bowel contents into the amniotic fluid and its
subsequent aspiration into the fetal lung. ARDS is a generalized inflammatory
disease of the lungs marked by intense leukocytic infiltration, edema and
atelectasis (partial lung collapse) resulting from sepsis, smoke inhalation and
other inflammatory lung conditions. IRDS is a disease of pre-term infants who
are born prior to the synthesis of adequate amounts of pulmonary surfactant
proteins. ATI intends to seek FDA approval to amend an approved IND and to
initiate Phase II clinical trials of KL4-Surfactant for the treatment of ARDS in
1997. ATI has amended an existing IRDS IND to permit the initiation of Phase II
clinical trials for the use of KL4-Surfactant to treat MAS. ATI met with the FDA
on March 10, 1997, to discuss its MAS development program. ATI received
constructive feedback from the FDA and intends to commence its MAS development
program on schedule.
    
ST-630

In October 1996, the Company acquired an exclusive license from the Wisconsin
Alumni Research Foundation ("WARF") relating to an active vitamin D analog,
ST-630, and its potential use in treating postmenopausal osteoporosis.
Osteoporosis is a disease characterized by decreased bone mass that leads to
reduced bone strength and an increased risk of fractures. Postmenopausal
osteoporosis is a major public health threat for approximately 7 to 20 million
American women. As a class, vitamin D analogs are commonly used therapies in
Europe and Japan for osteoporosis. Sumitomo Pharmaceuticals ("Sumitomo") and
Taisho Pharmaceuticals ("Taisho") have jointly licensed the right to develop,
manufacture and market ST-630 in Japan for the treatment of osteoporosis and are
presently conducting the equivalent of a Phase II clinical trial in Japan. The
Company believes that ST-630 may have an improved pharmacological profile
compared to earlier active vitamin D analogs. As a result of the execution of
the WARF license agreement, the Company has access to preclinical data generated
by Sumitomo and Taisho. The Company intends to seek FDA permission to initiate
clinical studies of ST-630 in the United States as a once-daily, orally
administered drug for the treatment of postmenopausal osteoporosis.
   
The Company was incorporated in Delaware on May 18, 1993, as MicroBio, Inc. and
subsequently changed its name to Discovery Laboratories, Inc. on May 23, 1996.
The Company did not commence its current operations until early 1996. The
Company's executive offices are located at 787 Seventh Avenue, 44th Floor, New
York, New York 10019. Its telephone number is (212) 554-4364 and its facsimile
number is (212) 554-4490. ATI was incorporated on September 11, 1996. Its
principal offices are located at 3359 Durham Road, Doylestown, PA, 18901. Its
telephone number is (215) 794-3064 and its facsimile number is (215) 794-3239.

                                  RISK FACTORS

AN INVESTMENT IN THE SECURITIES OFFERED HEREBY IS HIGHLY SPECULATIVE IN NATURE,
INVOLVES A HIGH DEGREE OF RISK AND SHOULD ONLY BE MADE BY AN INVESTOR WHO CAN
BEAR THE ECONOMIC RISK OF THE INVESTMENT FOR AN INDEFINITE PERIOD OF TIME AND
WHO CAN AFFORD A LOSS OF THE ENTIRE INVESTMENT. EACH PROSPECTIVE INVESTOR SHOULD
CAREFULLY CONSIDER THE RISKS ASSOCIATED WITH AN INVESTMENT IN THE COMPANY,
INCLUDING, WITHOUT LIMITATION, THE FOLLOWING RISK FACTORS, AS WELL AS OTHER
INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS BEFORE MAKING AN INVESTMENT.

DEVELOPMENT STAGE COMPANY; NO DEVELOPED OR APPROVED PRODUCTS; UNCERTAINTY OF 
FUTURE PROFITABILITY

The Company is at an early stage of development and has had almost no operations
to date. The potential products upon which the Company intends to focus its
development efforts are in the research and development stage and accordingly
the Company has not begun to market or generate revenues from the
commercialization of any of these products under development. The Company's
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,
which may never occur. Such clinical testing activities, together with resultant
increases in general and administrative expenses, are expected to result in
significant additional operating losses for the foreseeable future. The Company
currently is not profitable and does not anticipate generating significant
product revenues for the foreseeable future, if at all. The Company expects to
incur significant increasing operating losses over the next several years. To
achieve profitable operations, the Company, alone or with others, must
successfully develop and obtain regulatory approval for marketing its products.

   
The Company's operations are subject to numerous risks associated with the
establishment and development of products based upon innovative or novel
technologies. As a result, the Company must be evaluated in light of the
problems, delays, uncertainties and complications encountered in connection with
newly founded businesses. Some of these unanticipated problems may include
development, regulatory, manufacturing, distribution and marketing difficulties
that may be beyond the Company's financial or technical abilities to
satisfactorily resolve. In particular, there can be no assurance that the
Company's proposed drug products will not cause adverse effects that may prevent
them from being marketed, regardless of their efficacy. Certain of the Company's
initial drug candidates have not been the subject of Phase I clinical trials,
the purpose of which include identifying adverse effects, or have not been the
subject of such clinical trials at the dosage levels at which the Company
anticipates they will be administered in treating the indications for which the
Company is exploring their use. Moreover, those that have been the subject of
previous clinical trials may be shown to have previously undetected adverse
effects during the more extensive clinical trials that will be required prior to
their becoming candidates for marketing approval by the FDA. There can be no
assurance that the research and development activities funded by the Company
will be successful, that products under development will prove to be safe and
effective, that any of the preclinical or clinical development work will be
completed, that the Company will ever achieve any of its New Drug Application
("NDA") filing objectives with the FDA, that FDA approval will be attained for
such products, that the anticipated products will be commercially viable or
successfully marketed, that third parties do not hold proprietary rights that
preclude the Company from marketing its products, if any, or that, if the
products under development are approved by the FDA, the Company will ever
achieve significant revenues or profitable operations. See "Business."
    

EXTENSIVE GOVERNMENT REGULATION; UNCERTAINTY OF FDA AND OTHER GOVERNMENTAL 
APPROVAL OF PRODUCTS UNDER DEVELOPMENT

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 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 effectiveness
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

                                       5
<PAGE>
<PAGE>
   
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 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.
    

The regulatory status of the Company's three products under development is as
follows:
   
    SuperVent(TM):

    The FDA has approved, subject to certain modifications, a physician-
    sponsored IND for a randomized, double-blinded, placebo-controlled
    Phase I/II clinical trial of the Company's drug candidate, SuperVent(TM),
    for the treatment of CF. The Company entered into a clinical research
    agreement with the University of Utah Health Sciences Center ("UHSC") and
    began the aforementioned trial on March 17, 1997, pursuant to such
    agreement. Assuming successful completion of the Phase I/II clinical trial
    of SuperVent(TM), the Company anticipates that, at a minimum, at least one
    additional large-scale, multi-center, Phase III clinical trial will be
    necessary before the Company will be able to submit an NDA to the FDA
    requesting marketing approval for SuperVent(TM) for the treatment of CF.

    KL4-Surfactant:

    In July 1992, an IND submitted by Scripps relating to the use of
    KL4-Surfactant to treat IRDS was approved by the FDA. A Phase II clinical
    trial was subsequently completed by J&J. In 1991, an IND was submitted by
    J&J relating to the use of KL4-Surfactant to treat ARDS and was subsequently
    approved by the FDA. Both the IRDS IND and ARDS IND have been transferred to
    ATI. ATI intends to seek FDA approval to amend the approved ARDS IND and
    re-initiate Phase II clinical trials of KL4-Surfactant for the treatment of
    ARDS in 1997. ATI has amended the existing IRDS IND to permit the initiation
    of Phase II clinical trials of KL4-Surfactant to treat MAS. ATI met with the
    FDA on March 10, 1997, to discuss its MAS development program. ATI received
    constructive feedback from the FDA and intends to commence its development
    of KL4-Surfactant for MAS on schedule. The Company has not had any
    discussions with the FDA regarding clinical trials of KL4-Surfactant for the
    treatment of ARDS.

    ST-630:

    The Company intends to seek IND approval to initiate Phase I clinical
    studies of ST-630 as a once-daily, orally administered drug for the
    treatment of postmenopausal osteoporosis in the United States during 1997.
    Following receipt of FDA approval, if granted, the Company intends to
    conduct an initial dose-ranging study of ST-630 in humans. Based upon the
    results of the dose-ranging study, the Company may then either seek to
    further optimize the delivery of ST-630 by testing one or more alternative
    means of delivery or, assuming acceptable results, seek to initiate a
    large-scale, multi-center clinical trial in the United States. The Company
    has access to preclinical data generated by Sumitomo and Taisho with respect
    to ST-630 pursuant to the terms of the licensing arrangements described
    herein with respect to ST-630. The Company has not had any discussions with
    the FDA regarding ST-630. See "Business--Products and Technologies Under 
    Development--Vitamin D Analog for Treatment of Osteoporosis--ST-630."

Upon completion of clinical trials of a new drug product, FDA and foreign
regulatory authority marketing approval must be obtained before the new drug
product can be sold. NDAs submitted to the FDA generally take one to three years
to be approved. 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
    
                                       6
<PAGE>
<PAGE>

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 (nor has testing been completed). 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 the Company's
products under development, or limit the commercial use of such products, and
thereby could have a material adverse effect on the Company's business,
financial condition and results of operations.

TECHNOLOGICAL UNCERTAINTY AND OBSOLESCENCE

The market for biotechnology is characterized by rapidly changing technology and
evolving industry standards. The Company's future success will depend upon its
ability to develop and commercialize its existing products and to develop new
products and applications. There can be no assurance that the Company will
successfully complete the development of SuperVent(TM), KL4-Surfactant, ST-630
or any future product or that the Company's current or future products will
achieve market acceptance. Any delay or failure of SuperVent(TM),
KL4-Surfactant, ST-630 or any future product which the Company may develop in
achieving market acceptance would adversely affect the Company's business.

The Company's products under development are intended to treat diseases for
which other technologies and proposed treatments are rapidly developing. There
can be no assurance that any results of the Company's research and product
development efforts will not be rendered obsolete by research efforts and
technological activities of others, including the efforts and activities of
governments, major research facilities and large multinational corporations.

NEED FOR ADDITIONAL FINANCING; ISSUANCE OF SECURITIES; FUTURE DILUTION

   
In the future, the Company will require substantial additional funding to
conduct its research and product development activities and to manufacture and
market, if approved by the FDA or corresponding foreign regulatory authorities,
SuperVent(TM), KL4-Surfactant, ST-630 and any other products that the Company
may develop in the future. The Company anticipates that further funds may be
raised through collaborative ventures entered into with potential corporate
partners and/or additional debt or equity financings. While the Company may seek
to enter into collaborative ventures with corporate sponsors to fund some or all
of its research and development activities, as well as to manufacture or market
any products which may be successfully developed, the Company currently does not
have any such arrangements with corporate sponsors. The Company also has not
made arrangements to obtain any additional financing and there can be no
assurance that the Company will be able to obtain adequate additional financing
on acceptable terms, if at all, or that any such additional financing would not
result in significant dilution of stockholders' interests. Failure by the
Company to enter into collaborative ventures or to receive additional funding to
complete its proposed product development programs would have a material adverse
effect on the Company. If additional financing is not otherwise available, the
Company will be required to modify its business development plans or reduce or
cease certain or all of its operations.
    

DEPENDENCE ON PATENTS, LICENSES AND PROTECTION OF PROPRIETARY RIGHTS; RISK OF 
LOSS OF TECHNOLOGY

In order to justify the substantial investment of time and expense required to
develop and commercialize its products, the Company will seek proprietary
protection for its 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.
The Company's success will depend in part on the ability of the Company and the
Company's licensors to obtain effective patent protection for the Company's
proprietary technologies and products, defend such patents, preserve its 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 biotechnologies is highly uncertain and involves complex legal and
factual questions.

                                       7
<PAGE>
<PAGE>
   
To date, there has emerged no consistent policy at the United States Patent and
Trademark Office regarding the breadth of claims allowed in biotechnology
patents or the degree of protection afforded under such patents.

There are various combinations of United States and foreign patents and patent
applications (including international applications filed under the Patent
Cooperation Treaty) that have been issued or filed with respect to the products
and technologies under development by the Company. See "Business--Licensing
Arrangements." These patents and patent applications have been licensed to the
Company (with certain limited exceptions, on an exclusive worldwide basis).
Although the licensors under such licenses have retained control of the patent
prosecution process, the Company is responsible for the expenses of prosecuting
the patents and patent applications (i.e., the fees of patent counsel and any
domestic or foreign filing fees that are applicable). Patent applications may be
expected to remain pending for several years before the issuance of a patent, if
any, and the prosecution of patent applications with respect to the Company's
products may entail considerable expense to the Company.
    

There can be no assurance that patents will issue as a result of any of the
pending patent applications relating to the Company's products and technologies
or that the issued patents and any patents resulting from the pending patent
applications will be sufficiently broad to afford protection to the Company
against competitors with similar products and technologies. In addition, there
can be no assurance that such patents will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company. The commercial success of the Company will also
depend upon its avoidance of infringement of patents issued to competitors. A
United States patent application is maintained under conditions of
confidentiality while the application is pending, so the Company cannot
determine the inventions being claimed in pending patent applications filed by
third parties. Litigation may be necessary to defend or enforce the Company's
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, even in those instances in which the outcome is
favorable to the Company, and can result in the diversion of substantial
resources from the Company's other activities. An adverse outcome could subject
the Company to significant liabilities to third parties, require the Company to
obtain licenses from third parties, or require the Company to alter its products
or processes or cease altogether any related research and development activities
or product sales, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business--Patents, Licenses and Proprietary Rights."

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 such employees' ideas,
developments, discoveries and inventions. In addition, the Company seeks to
obtain such agreements from its 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 the proposed projects of the Company, disputes may arise as to
the proprietary rights to such information which may not be resolved in favor of
the Company. In addition, the Company also relies on trade secrets and
proprietary know-how that it seeks to protect in part by its confidentiality
agreements with its employees, consultants, advisors or others. There can be no
assurance that these agreements will not be breached, that the Company would
obtain adequate remedies for any breach, or that the Company's trade secrets or
proprietary know-how will not otherwise become known or be independently
developed by competitors in such a manner that the Company has no legal
recourse. See "Business--Patents, Licenses and Proprietary Rights."

   
The Company is dependent on licensing arrangements for access to its products
under development, and the Company is required to make certain payments and
satisfy certain performance obligations in order to maintain the effectiveness
of such licensing arrangements. The Company is further responsible for the cost
of filing and prosecuting patent applications and maintaining issued patents.
See "Business--Patents, Licenses and Proprietary Rights." If the Company does
not meet its due diligence and/or financial obligations under its license
agreements in a timely manner, the Company could lose the rights to its
proprietary technology, which would have a material adverse effect on the
Company.

DEPENDENCE ON THIRD PARTY SUPPLIERS; LACK OF MANUFACTURING CAPABILITY

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. To be
successful, the Company's products must be manufactured in commercial quantities
under good manufacturing practice ("GMP") requirements presented 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 are also inspected by the FDA if their drugs are marketed
in the United States. Failure of the foreign or domestic suppliers of the
Company'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 active compound in the Company's SuperVent(TM) product under development,
tyloxapol, 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. The Company does not presently have an agreement
with Sanofi to supply any additional material either in connection with a Phase
III 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 until the Company plans to initiate a
Phase III clinical trial. 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 has entered into an agreement 
with Cook Imaging Corporation for the packaging and storage, under sterile and 
stable conditions, of tyloxapol.

ATI has acquired from J&J experimental compounds, the KL4 peptides and
manufacturing equipment needed to produce and meet the Company's requirements
for clinical supplies of KL4-Surfactant. ATI has entered into an agreement with
Cook Imaging Corporation for the development of the manufacturing process to be
employed in the KL4-Surfactant program. ATI intends to seek an agreement with a
third party manufacturer to produce KL4-Surfactant on an ongoing basis during
1997. There can be no assurance that agreement for such production will be
reached. Failure to identify and reach an agreement with a third party
manufacturer would substantially delay the Company's development of
KL4-Surfactant and could have a material adverse effect on the Company's
business, financial condition and results of operations.

The Company is in the process of negotiating an exclusive supply agreement with
Tetrionics, Inc. ("Tetrionics") to manufacture and supply the Company with
ST-630 for the Company's investigational and commercial purposes. Tetrionics
presently manufactures and supplies ST-630 to Penederm, Inc. for investigational
topical use for the treatment of psoriasis. There can be no assurance that the
Company will be able to reach an agreement with Tetrionics on terms acceptable
to the Company, if at all. Failure to achieve an agreement could substantially
delay the Company's development of ST-630.
    

DEPENDENCE ON OTHERS FOR CLINICAL DEVELOPMENT OF, REGULATORY APPROVALS FOR AND
MANUFACTURING AND MARKETING OF PHARMACEUTICAL PRODUCTS

The Company's strategy is to seek to enter into collaborative agreements with
pharmaceutical companies for the research and development, clinical testing,
manufacturing, marketing and commercialization of certain of its products. The
Company will therefore be dependent upon the expertise and dedication of
sufficient resources by third parties to develop and commercialize certain of
its proposed products. The Company may in the future grant to its collaborative
partners, if any, rights to license and commercialize any pharmaceutical
products developed under these collaborative agreements and such rights would
limit the Company's flexibility in considering alternatives for the
commercialization of such products. Under such agreements, the Company expects
to rely on its collaborative partners to conduct research and clinical trials,

                                       9
<PAGE>
<PAGE>

   
manufacture, market and commercialize certain of its products. Although the
Company believes that its collaborative partners may have an economic motivation
to commercialize the pharmaceutical products which they may license from the
Company, the amount and timing of resources devoted to these activities
generally will be controlled by each such individual partner. There can be no
assurance that the Company will be successful in establishing any collaborative
arrangements, or that, if established, such future partners will be successful
in developing and commercializing products or that the Company will derive any
revenues from such arrangements.

The Company has recently entered into a clinical research agreement with the
University of Utah Health Sciences Center for clinical trials of SuperVent(TM)
in the treatment of CF. This Phase I/II clinical trial began on March 17, 1997.

ATI and Scripps have entered into a sponsored research agreement (the "Sponsored
Research Agreement") supporting continuing research by Charles G. Cochrane,
M.D., and Susan Revak of Scripps. Pursuant to the Sponsored Research Agreement,
ATI will contribute $460,000 annually to Scripps' KL4-Surfactant research
efforts for an initial two-year period. ATI has an option to acquire an
exclusive worldwide license to make, have made, sell or use technology developed
under the agreement, which it is required to exercise within 180 days from
receipt of notice from Scripps of the development of such technology. Scripps
will own all technology that it develops pursuant to work performed under the
Sponsored Research Agreement. ATI has the right to receive 50% of the net
royalty income received by Scripps for inventions jointly developed by ATI and
Scripps to the extent ATI does not exercise its option with respect to such
inventions. ATI has entered into consulting agreements with certain key research
personnel at Scripps. See "Executive Compensation and Employment and Consulting
Agreements."
    

The Company has not entered into any collaborative arrangements with respect to
its ST-630 product.

LACK OF MARKETING CAPABILITY AND EXPERIENCE

It is the Company's long-term goal to manufacture and market SuperVent(TM) for
CF and possibly certain of its other products through a direct sales force (or,
in the case of CF, possibly through the distribution capabilities of the Cystic
Fibrosis Foundation), if and when necessary regulatory approvals are obtained.
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 sale of its
products. The inability of the Company to successfully establish a sales force
or enter into third party distribution, marketing and selling arrangements for
its anticipated products would have a material adverse effect on the Company's
business, financial condition and results of operations.

DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS

   
The Company will be highly dependent upon its officers and directors, as well as
its medical advisory board and scientific advisory board members, consultants
and collaborating scientists. The management of the Company currently consists
of 11 persons. The loss of the services of any of these individuals or of any of
its medical advisory board or scientific advisory board members, consultants
and/or collaborating scientists could have a material adverse effect on the
Company's business, financial condition and results of operations. The Company
has not obtained, and does not intend to obtain, key-man life insurance on any
of its key personnel.
    

Since competent management personnel are in great demand, there can be no
assurance that the Company will be able to attract and retain such personnel on
a timely basis and on terms acceptable to the Company. The Company believes that
its success will depend in large part upon attracting and retaining
highly-skilled managerial and other employees.

                                       10

NO ASSURANCE OF ADDITIONAL PRODUCTS; RISKS ASSOCIATED WITH CERTAIN DRUG 
CANDIDATES

Although the Company intends to devote substantial resources to the development
and commercialization of SuperVent(TM), KL4-Surfactant and ST-630, it will
explore the acquisition and subsequent development and commercialization of
additional pharmaceutical products and technologies. There can be no assurance
that the Company will be able to identify any additional products or
technologies, that it will be able to license any such technologies on
acceptable terms or that, even if suitable products or technologies are
identified, the Company will have sufficient resources to pursue any such
products or technologies to commercialization.

   
Each of the Company's products may represent risks that are presently unknown to
the Company and which may be the basis of an adverse regulatory determination
with regard to the development and commercialization of such products. Tyloxapol
has been used in low concentrations by the pharmaceutical industry for over 40
years without any reported significant adverse effects. However, since
SuperVent(TM) will likely be using a higher dosage of tyloxapol, the Company
will have to demonstrate safety at a tyloxapol dose significantly higher than
that used previously.

Preclinical studies of KL4-Surfactant have revealed no local or systemic
toxicity associated with test material having KL4-Surfactant concentrations well
in excess of those intended to be clinically tested. These studies also revealed
a lack of mutagenicity and immunogenicity. However, the Company will have to
demonstrate the effectiveness of KL4-Surfactant at a safe dosage level prior to
marketing KL4-Surfactant for the treatment of MAS, ARDS and/or IRDS.

The Company will have to demonstrate the effectiveness of ST-630 at a safe
dosage level in order to receive marketing approval in the United States for the
treatment of postmenopausal osteoporosis. Prior studies of vitamin D analogs
such as ST-630, which are administered in their active form, have been
associated with hypercalcemia in a number of patients. Hypercalcemia is
characterized by elevated calcium levels in the blood above a generally accepted
range. The Company believes that this risk of hypercalcemia may be the primary
reason why active vitamin D analogs have only been tested on a limited basis in
the United States, which is generally considered to be a high calcium
consumption country. The Company has not yet conducted the clinical studies that
will be required to determine whether ST-630 presents this same risk of
hypercalcemia. Although the Company believes that, based upon the results of
prior studies of ST-630, this compound may have a higher potency and greater
therapeutic window as compared to other active vitamin D analogs, there can be
no assurance that the Company will be able to demonstrate a dosage level for
ST-630 that will be both safe and effective.

CONTROL BY CURRENT OFFICERS, DIRECTORS AND PRINCIPAL STOCKHOLDERS

The Company's directors, executive officers and principal stockholders
beneficially own approximately 24.40% of the outstanding shares of Common Stock,
assuming (a) the conversion of all outstanding shares of Series A Preferred
Stock and assuming issuance of the shares of Common Stock (i) subject to the
Common Placement Warrants and (ii) issuable upon conversion of the Series A
Preferred Stock subject to the Preferred Placement Warrants and (b) the exercise
of all outstanding vested options. Accordingly, the Company's executive
officers, directors, principal stockholders and certain of their affiliates will
have the ability to exert substantial influence over the election of the
Company's Board of Directors and the outcome of issues submitted to the
Company's stockholders. Such a concentration of ownership may have the effect of
delaying or preventing a change in control of the Company, including
transactions in which shareholders might otherwise recover a premium for their
shares over their current market prices. See "Principal Stockholders."
    

COMPETITION

   
The Company is engaged in a highly competitive field of pharmaceutical research.
Competition from numerous existing companies and others in respiratory,
anti-inflammatory and anti-oxidant research and the fields of CF, MAS, ARDS,
IRDS and postmenopausal osteoporosis is intense and expected to increase. In
addition, the Company expects to compete with 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
    
                                       11
<PAGE>
<PAGE>

   
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 have a
significant competitive advantage. There can be no assurance that any products
developed by the Company's competitors will not be more effective than any
developed by the Company.
    

RISK OF PRODUCT LIABILITY; NO INSURANCE COVERAGE

   
Should the Company develop any products, the marketing of such products, through
third party arrangements or otherwise, may expose the Company to product
liability claims in the event that the use or misuse of pharmaceutical products
manufactured by, or under license from, the Company results in adverse effects.
The Company presently carries product liability insurance which covers adverse
events in connection with its Phase I/II clinical trial of SuperVent(TM) at the
University of Utah Health Science Center. The Company may be required to obtain
additional product liability insurance coverage prior to initiation of clinical
trials of its other proposed products. In addition, the Company intends to
obtain product liability insurance coverage before commercialization of its
proposed products. There can be no assurance that adequate insurance coverage
will be available at an acceptable cost, if at all. In addition, there can be no
assurance that a product liability claim, even if the Company has insurance
coverage, would not materially adversely affect the Company's business,
financial condition and results of operations.
    

UNCERTAINTY OF PRODUCT PRICING AND REIMBURSEMENT; HEALTH CARE REFORM AND RELATED
MEASURES

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, and the Company expects that there will continue to be,
a number of federal and state proposals to implement similar government control.
Presently, the United States Congress is considering a number of legislative and
regulatory reforms that may affect companies engaged in the health care industry
in the United States. Pricing constraints on the Company's products, if
approved, could have a material adverse effect on the Company. Although the
Company cannot predict whether these proposals will be adopted or what effects
such proposals may have on its business, the existence and pendency of such
proposals could in general have a material adverse effect on the Company. In
addition, the Company's ability to commercialize potential pharmaceutical and/or
biotechnology products may be adversely affected to the extent that such
proposals have a material adverse effect on other companies that are prospective
collaborators with respect to any of the Company's product candidates.

In the United States and elsewhere, successful commercialization of the
Company's products will depend in part on the availability of reimbursement to
the consumer from third party health care payers, such as government and private
insurance plans. There can be no assurance that such reimbursement will be
available or will permit price levels sufficient to realize an appropriate
return on the Company's investment in product development. Third party health
care payers are becoming increasingly cost conscious in determining which
pharmaceutical products they will and will not reimburse. If the Company
succeeds in bringing one or more products to the market, there can be no
assurance that these products will be considered cost effective and that
reimbursement to the consumer will be available or will be sufficient to allow
the Company to sell its products on a competitive basis. See "Risk Factors--
Extensive Government Regulation; Uncertainty of FDA and Other Governmental
Approval of Products under Development."

CERTAIN INTERLOCKING RELATIONSHIPS; POTENTIAL CONFLICTS OF INTEREST

   
The Chairman of the Company is a full-time officer of Paramount. In addition,
Kenneth Johnson, the Director of Business Development of the Company, is a
Technology Associate of Paramount Capital Investments, LLC ("Paramount
Investments"), an affiliate of Paramount. See "Management" and "Certain
Transactions". Each of these individuals devotes only a portion of his time to
the business of the Company. Paramount acted as placement agent for the Company
in a private placement of its equity securities conducted during June through
November 1996 (the "Unit Offering"), pursuant to which the Selling
Securityholders acquired their Common Stock and Series A Preferred Stock. The
Company currently shares its office space with Paramount. Paramount Investments
is a merchant banking firm specializing in biotechnology companies. In the
regular course of its business, Paramount Investments identifies, evaluates and
pursues
    
                                       12
<PAGE>
<PAGE>

investment opportunities in biomedical and pharmaceutical products, technologies
and companies. Delaware corporate law requires that any transactions between the
Company and any of its affiliates be on terms that, when taken as a whole, are
substantially as favorable to the Company as those then reasonably obtained from
a person who is not an affiliate in an arm's-length transaction. Nevertheless,
Paramount Investments is not obligated pursuant to any agreement or
understanding with the Company to make any additional products or technologies
available to the Company, and there can be no assurance, and purchasers of the
Common Stock should not expect, that any biomedical or pharmaceutical product or
technology identified by Paramount Investments or any other affiliates of
Paramount or Paramount Investments in the future will be made available to the
Company. The Company maintains a policy that, subject to the approval of a
majority of the disinterested directors of the Company, the Company may
compensate directors of the Company in the form of cash bonuses and/or stock
options, in connection with new drug candidates licensed or acquired by the
Company which were identified and introduced to the Company by such persons. In
addition, certain of the officers, directors, consultants, and advisors to the
Company may from time to time serve as officers, directors, consultants or
advisors to other biopharmaceutical or biotechnology companies. There can be no
assurance that such other companies will not in the future have interests in
conflict with those of the Company.

ABSENCE OF MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

To date, there has been no public market for the securities of the Company. The
market price, if any, of the Common Stock, like that of many other
development-stage public pharmaceutical or biotechnology companies, may be
highly volatile. Factors such as announcements of technological innovations or
new commercial products by the Company or its competitors, disclosure of results
of preclinical and clinical testing, adverse reactions to products, governmental
regulation and approvals, developments in patent or other proprietary rights,
public or regulatory agency concerns as to the safety of any products developed
by the Company and general conditions may have a significant or adverse effect
on the market price of the Common Stock.

UNCERTAINTY OF LISTING ON NASDAQ SMALL-CAP MARKET; POSSIBLE DELISTING FROM 
NASDAQ SMALL-CAP MARKET; MARKET ILLIQUIDITY

   
The Company intends to apply for listing of the Common Stock on the Nasdaq
Small-Cap Market under the symbol "DSCO". The Company believes that it will meet
the currently proposed criteria for such listing on such market at the time of
effectiveness of the registration statement of which this Prospectus is a part,
including, without limitation: (i) net tangible assets of at least $4 million;
(ii) an operating history of over one year; (iii) a market value of its publicly
held shares of at least $5 million; (iv) at least 300 holders of the Common
Stock; (v) at least three market makers; and (vi) and an initial minimum bid
price of at least $4.00. However, there can be no assurance that the Common
Stock will be listed on the Nasdaq Small-Cap Market. The prices of the Common
Stock which may be obtained on the Nasdaq Small-Cap Market are not necessarily
related to the Company's assets, book value, results of operations or any other
established criteria of value, and should not be regarded as any indication of
future market price of the Common Stock.


Assuming the Nasdaq Small-Cap Market listing of the Common Stock is approved,
continued inclusion of the Common Stock on the Nasdaq Small-Cap Market is
proposed to require: (i) that the Company maintain at least $2,000,000 in net
tangible assets, a market capitalization of $35 million or $500,000 of net
income in two out of three years; (ii) a market value of its publicly held
shares of at least $1 million; (iii) that the minimum bid price for the Common
Stock be at least $1.00 per share; (iv) that the public float of the Common
Stock consist of at least 500,000 shares; (v) that the Common Stock have at
least two active market makers; and (vi) that the Common Stock be held by at
least 300 holders. If the Company is unable to satisfy such maintenance
requirements, the Common Stock may be delisted from the Nasdaq Small-Cap Market.
In such event, trading, if any, in the Common Stock would thereafter be
conducted in the over-the-counter market in the "pink sheets" or the OTC
Bulletin Board. Consequently, the liquidity of the Common Stock could be
materially and adversely impaired, not only in the number of securities that
can be bought and sold at a given price, but also through delays in the timing
of transactions and reduction in security analysts' and the media's coverage of
the Company, which could result in lower prices for the Common Stock than might
otherwise be attained and could also result in a larger spread between the bid
and asked prices for the Common Stock. See "Risks of Low Price Stock; Possible
Effect of "Penny Stock" Rules on Liquidity for the Common Stock."

RISKS OF LOW-PRICED STOCK; POSSIBLE EFFECT OF "PENNY STOCK" RULES ON LIQUIDITY
FOR THE COMMON STOCK

The Securities Exchange Act of 1934, as amended (the "Exchange Act") requires
additional disclosure relating to the market for penny stocks in connection with
trades in any stock defined as a penny stock. The Commission's regulations
generally define a penny stock to be any equity security that has a market price
of less than $5.00 per share, subject to certain exceptions. Such exceptions
include any equity security listed on a national securities exchange or quoted
on Nasdaq and any equity security issued by an issuer that has (i) net tangible
assets of at least $2 million, if such issuer has been in continuous operation
for three years, (ii) net tangible assets of at least $5 million, if such issuer
has been in continuous operation for less than three years, or (iii) average
annual revenue of at least $6 million, if such issuer has been in continuous
operation for less than three years. There can be no assurance that the Company
will meet the requirements of the foregoing exceptions.

   
In addition, if the Company's securities are not listed on a national securities
exchange or quoted on Nasdaq or fail to meet the net tangible asset or annual
revenue tests set forth above, but are quoted on the OTC Bulletin Board (as to
which there can be no assurance), then trading in the Company's securities would
be regulated pursuant to Rules 15-g-1 through 15-g-6 and 15-g-9 promulgated
under the Exchange Act for non-Nasdaq and non-exchange listed securities. Under
such rules, broker-dealers who recommend such securities to persons other than
established customers and "accredited investors" must make a special written
suitability determination that the penny stock is a suitable investment for the
purchaser and receive the purchaser's written agreement to this transaction.
Consequently, such Exchange Act rules may affect the ability of broker-dealers
to make a market in such shares and may affect the ability of holders of Common
Stock to sell such stock in the secondary market. Securities are exempt from
these rules if the market price of such securities is at least $5.00 per share.
    

Unless exempt, the rules require delivery, 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 sales 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.

If the Common Stock is subject to the rules on penny stocks, the market
liquidity for such securities could be materially and adversely affected.

POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE

   
As of December 13, 1996, 6,712,256 shares of Common Stock were issued and
outstanding, 4,512,000 of which the Company believes are "restricted securities"
and under certain circumstances may, in the future, be sold in compliance with
Rule 144. Assuming the availability of Rule 144, the Company believes that of
the outstanding shares of Common Stock, 1,132,500 "restricted" shares of Common
Stock are currently eligible for sale and up to 3,379,500 "restricted" shares
will be eligible in 1998 and 1999, in each case subject to certain volume
limitations and manner of sale requirements imposed by Rule 144. In general,
under Rule 144, subject to the satisfaction of certain other conditions, a
person, including an affiliate of the Company, who beneficially owned restricted
shares of Common Stock for at least two years is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of one
percent of the total number of outstanding shares of the same class, or if the
Common Stock is quoted on Nasdaq, a national securities exchange or the OTC
Bulletin Board, the average weekly trading volume during the four calendar weeks
immediately preceding the sale. A person who presently is not and who has not
been an affiliate of the Company for at least three months immediately preceding
the sale and who has beneficially owned the shares of Common Stock for at least
three years is entitled to sell such shares under Rule 144(k) without regard to
the volume limitations described above. In addition, the Company currently has
issued and outstanding options to purchase an aggregate of 685,500 shares of
Common Stock (excluding the Placement Agent Warrants), 481,125 of which are
subject to vesting over the next 33 months. The Commission has recently adopted
revisions to Rule 144 and Rule 144(k), the effect of which will be to shorten
the holding period under Rule 144 from two years to one year and to shorten the
holding period under Rule 144(k) from three years to two years.
    

                                       14

<PAGE>

No prediction can be made as to the effect, if any, that sales of shares of
Common Stock or the availability of such shares for sale will have on the market
prices that may be quoted from time to time on the OTC Bulletin Board, or Nasdaq
if quoted thereon. Nevertheless, the possibility that substantial amounts of
Common Stock may be sold in the public market may adversely effect the
prevailing market prices for the Common Stock and could impair the Company's
ability to raise capital in the future through the sale of equity securities.
Actual sales or the prospect of future sales of shares of Common Stock under
Rule 144 or otherwise may have a depressive effect upon the price of the Common
Stock and the market therefor.

ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND 
DELAWARE LAW

   
The Company's Certificate of Incorporation, as amended, authorizes the issuance
of up to 10,000,000 shares of preferred stock, of which 2,200,256 shares are
currently outstanding (without giving effect to any shares issuable upon
exercise of the Placement Agent Warrants). The Board of Directors has been
granted 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, the Board of Directors could
authorize the issuance of a series of preferred stock which would grant to
holders the preferred right to the assets of the Company upon liquidation, the
right to receive dividend coupons before dividends would be declared to Common
Stockholders, and the right to the redemption of such shares, together with a
premium, prior to the redemption of Common Stock. Common stockholders have no
redemption rights. In addition, the Board could issue large blocks of preferred
stock to fend against unwanted tender offers or hostile takeovers without
further shareholder approval. See "Description of Securities." The Company is
subject to Section 203 of the General Corporation Law of the State of Delaware
which, subject to certain exceptions, prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that such stockholder became an
interested stockholder. 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 foregoing
provisions could have the effect of discouraging others from making tender
offers for the Company's shares and, as a consequence, they also may inhibit
fluctuations in the market price of the Company's shares that could result from
actual or rumored takeover attempts. Such provisions also may have the effect of
preventing changes in the management of the Company.
    

DIVIDENDS UNLIKELY

The Company has never paid cash dividends on its capital stock and does not
anticipate paying any cash dividends for the foreseeable future.

POTENTIAL CONVERSION PRICE RESET OF SERIES A PREFERRED STOCK

Pursuant to the Unit Offering, the Company consummated an offering of Units
consisting of Series A Preferred Stock and Common Stock. 2,200,256 shares of
Series A Preferred Stock were included in the Units sold in the Unit Offering.
Shares of Series A Preferred Stock are convertible at the option of the holders
thereof into shares of Common Stock of the Company, at an initial conversion
rate corresponding to a conversion price equal to $2.50 per share. The
conversion price in effect immediately prior to the date that is 12 months after
the first date on which the shares of Common Stock are publicly traded (the
"Reset Date") will be adjusted effective as of the Reset Date if the average
closing bid price of the Common Stock for the 30 consecutive trading days
immediately preceding the Reset Date is less than 135% of the then applicable
conversion price. Any such reset of the conversion price applicable to the
Series A Preferred Stock would have a dilutive effect on purchasers of the
Common Stock offered hereby.

FORWARD LOOKING STATEMENTS

Certain of the statements set forth in this Prospectus, including, without
limitation, the Company's research and development programs, the seeking of
joint development or licensing arrangements with pharmaceutical companies, the
research and development of particular compounds and technologies for particular
indications and the period of time for which the Company's existing resources
will enable the Company to fund its operations and to meet the initial listing
requirements for the quotation of its securities on the Nasdaq Small-Cap Market,
are forward-looking and based upon the

                                       15
<PAGE>
<PAGE>

   
Company's current belief as to the outcome, occurrence and timing of future
events or current expectations and plans. All such statements involve
significant risks and uncertainties. Many important factors affect the Company's
ability to achieve the stated outcomes and to successfully develop and
commercialize its product candidates including, among other things, the ability
to obtain substantial additional funds, to obtain and maintain all necessary
patents or licenses, to demonstrate the safety and efficacy of product
candidates at each state of development, to meet applicable regulatory standards
and receive required regulatory approvals, to meet obligations under its license
agreements, to be capable of producing drug candidates in commercial quantities
at reasonable costs, to successfully compete against other products and to
market products in a profitable manner. As a result, there also can be no
assurance that these statements included in the Prospectus will prove to be
accurate. In light of the significant uncertainties inherent in these statements
included herein, the inclusion of such information should not be regarded as a

                                 USE OF PROCEEDS

The Company will not receive any proceeds from the sale of shares of Common
Stock. The Company is not expected to receive any proceeds from the exercise of
the Placement Agent Warrants since the Placement Agent Warrants may be exercised
pursuant to cashless exercise provisions. In the event that the Placement Agent
Warrants are exercised for cash, the Company intends to use such net cash
proceeds (after estimated offering expenses of this Offering of approximately
$300,000) for general working capital purposes. Proceeds, if any, from the
exercise for cash of all the Placement Agent Warrants, before deduction of
estimated expenses of this Offering, would be approximately $2,475,000. Whether,
how and to what extent any of the Placement Agent Warrants will be exercised,
and whether the Placement Agent Warrants are exercised for cash or not, cannot
be predicted by the Company.

                                 DIVIDEND POLICY

The Company has not paid any cash dividends on its Common Stock since its
formation. The payment of dividends, if any, in the future, with respect to the
Common Stock, is within the discretion of the Board of Directors of the Company
and will depend on the Company's earnings, capital requirements, financial
condition and other relevant factors. The Board of Directors of the Company does
not presently intend to declare any dividends on the Common Stock in the
foreseeable future. 

The Company anticipates that all earnings and other resources of the Company, 
if any, will be retained by the Company for investment in its business.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                   FINANCIAL CONDITION AND PLAN OF OPERATIONS

GENERAL

   
The Company was originally organized as MicroBio, Inc. on May 18, 1993. The
Company had limited operations prior to January 1995. In May 1996, the Company
amended its Certificate of Incorporation to effect a name change to its current
name, Discovery Laboratories, Inc. In April 1996, the Company entered into a
three-year employment agreement with James S. Kuo, M.D., whereby Dr. Kuo agreed
to serve as President and Chief Executive Officer of Discovery. In October 1996,
ATI entered into a four-year employment agreement with Robert J. Capetola, 
Ph.D., whereby Dr. Capetola became the President, Chief Executive Officer and 
Chairman of the Board of ATI.

Since its inception, the Company has concentrated its efforts and resources in
the development and commercialization of pharmaceutical products and
technologies. The Company has been unprofitable since its founding and has
incurred a cumulative net loss of approximately $3,254,000 as of December 31,
1996. 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 the SuperVent(TM) and ST-630
products, the KL4-Surfactant technology 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 generate revenues and the Company does not expect
to achieve 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 the SuperVent(TM) and ST-630 products, the
KL4-Surfactant technology or any other products or technologies that it may
acquire or develop. See "Risk Factors--Development Stage Company; No Developed
or Approved Products; Uncertainty of Future Profitability."
    

PLAN OF OPERATION

   
The Company is currently engaged in the development and commercialization of
investigational drugs that have previously been tested in humans or animals. In
March 1996, the Company executed a license agreement with CMHA as owner and
licensor of the Company's tyloxapol patents and patent applications. The Company
paid $86,400 as a license issue fee to CMHA to obtain its license, which fee was
capitalized and is being amortized over the term of the license. In September
1996, the Company entered into a license agreement (the "WARF License
Agreement") with WARF relating to an active vitamin D analog, ST-630, and its
potential use in treating postmenopausal osteoporosis. The Company paid a
$400,000 initial fee to WARF upon execution of the WARF License Agreement. In
October 1996, ATI executed a sublicense agreement with J&J and J&J's
wholly-owned subsidiary, Ortho Pharmaceutical Corporation, granting an exclusive
sublicense of the KL4-Surfactant technology to ATI in exchange for an initial
$200,000 license fee, additional milestone payments, royalties and common stock
of ATI. J&J is contributing its existing KL4-Surfactant raw material inventory
and specialized manufacturing equipment, with an estimated original cost of $3.3
million, to ATI in exchange for shares of nonvoting Series B Preferred Stock of
ATI having a $2.2 million liquidation preference.

The Company anticipates that during the next 12 months it will conduct
substantial research and development of the SuperVent(TM), KL4-Surfactant and
ST-630 products, including, without limitation, a Phase I/II clinical trial of
SuperVent(TM) for the treatment of CF that was commenced on March 17, 1997 (and,
assuming the successful completion of such clinical trial, a Phase II clinical
trial of SuperVent(TM) for the treatment of chronic bronchitis) and Phase II
clinical trials of KL4-Surfactant for the treatment of MAS and ARDS. The Company
also intends to initiate clinical studies of ST-630 as a once-daily, orally
administered drug for the treatment of postmenopausal osteoporosis in the United
States during the next 12 months. Certain of the planned clinical trials of the
Company's products in development require the receipt of FDA approvals, and
there can be no assurance as to the receipt or the timing of receipt of such
approvals. See "Business--Products and Technologies Under Development," and
"--Government Regulation; Orphan Drug Designation." The Company may seek to
acquire additional products and technologies in the future. Should the Company
acquire such additional products or technologies, it is anticipated that such
additional products or technologies will require substantial resources for
research, development and clinical evaluation. However, there can be no
assurance that the Company will be able to obtain the additional financing
necessary to acquire and develop such products and technologies. Furthermore,
there can be no assurance
    
                                       19
<PAGE>
<PAGE>

that changes in the Company's research and development plans or other changes
which would or could alter the Company's operating expenses will not require the
Company to reallocate funds among its planned activities and curtail certain
planned expenditures. In such event, the Company may need additional financing.
There can be no assurance as to the availability or the terms of any required
additional financing, when and if needed. In the event that the Company fails to
raise any funds it requires, it may be necessary for the Company to
significantly curtail its activities or cease operations.

   
The Company has recently hired seven new employees to serve as Vice President of
Clinical Affairs, Vice President of Regulatory Affairs, Director of Business
Development and Project Manager, respectively, of Discovery, and Vice President
of Biometrics, Vice President of Clinical Research and Director of Clinical
Research, respectively, of ATI. The timing and cost of hiring any additional
employees may vary depending on need and cannot currently be predicted with any
certainty.

ATI has entered into an agreement with Cook Imaging Corporation for the
development of the manufacturing process to be employed in the KL4-Surfactant
program. It is also anticipated that, over the next 12 months, ATI will enter
into an agreement with a third party for the purpose of supplying KL4-Surfactant
to ATI. No specific supplier has been identified to date.
    

LIQUIDITY AND CERTAINTY

   
The Company anticipates that its current resources will permit it to meet its
business objectives until approximately June 1998. 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 Company devotes to the development of manufacturing and
marketing capabilities, technological advances, status of competitors and
abilities of the Company to establish collaborative arrangements with other
organizations, and as such there can be no assurance that the Company will not
be required to raise additional capital prior to June 1998 or, in general, that
the Company will be able to achieve its business objectives.

The Company experienced a substantial increase in expenses during 1996 as
compared to earlier periods due to expenses incurred in connection with the
Unit Offering. See "Certain Transactions."

Discovery Laboratories, Inc. ("Discovery" and together with its majority-owned
subsidiary, Acute Therapeutics, Inc. ("ATI"), the "Company") is a development
stage pharmaceutical company that is focused on acquiring, developing and
commercializing proprietary, investigational drugs that have previously been
tested in humans or animals. The Company's strategy is to conduct preclinical
and clinical studies on investigational drugs licensed from third parties,
either alone or in collaboration with corporate partners. The Company may also
seek to enter into collaborations with corporate partners for manufacturing and
marketing of such drugs.
    

PRODUCTS AND TECHNOLOGIES UNDER DEVELOPMENT

SUPERVENT(TM)

    BACKGROUND

The Company is developing SuperVent(TM) as a stable aerosolized,
multidimensional therapy for airway diseases characterized by inflammation,
injurious oxidation and excessive sputum. SuperVent's(TM) active compound is
tyloxapol, a non-anionic, alkylaryl polyether alcohol polymer which has been
safely used as an emulsifying agent in drug formulations by the United States
pharmaceutical industry for over 40 years. Tyloxapol is a slightly viscous,
amber liquid that is slowly but freely soluble in water and has a pleasant,
slightly aromatic odor. The compound is generally recognized as relatively
non-toxic to human cells and the mammalian lung. Tyloxapol had no reported
respiratory toxicity in rhesus monkeys when administered daily by aerosol for a
year at 15% weight/volume. The compound is not orally absorbed. Experimental
research conducted by the Company's scientific founders has led to the discovery
that tyloxapol appears to possess biological activities beyond its
well-recognized emulsification properties. Tyloxapol is thought to have three
mechanisms of action:

                  o Anti-inflammatory activity

                  o Anti-oxidant activity

                  o Mucolytic activity

The combination of the above pharmacologic activities is not presently found in
any single, safe, effective therapy for cystic fibrosis or chronic bronchitis.
If successfully developed and approved, SuperVent(TM) is intended to be used
daily by cystic fibrosis and chronic bronchitis patients in the home and
hospital to preserve pulmonary function and aid mucus expectoration.

   
The Company has obtained an exclusive, worldwide license from The
Charlotte-Mecklenburg Hospital Authority ("CMHA") which covers two issued United
States patents and two pending United States and corresponding foreign patent
applications relating to pharmaceutical preparations containing high
concentrations of tyloxapol and the use of tyloxapol for the treatment of a
variety of respiratory and other diseases involving inflammation and oxidative
damage. The United States Food and Drug Administration (the "FDA") has granted
orphan drug status for the use of tyloxapol to treat cystic fibrosis ("CF"). See
"Government Regulation; Orphan Drug Designation." The Company has commenced
clinical testing of SuperVent(TM) for the treatment of CF and intends to
clinically test SuperVent(TM) for the treament of chronic bronchitis. Because
Phase I clinical studies of tyloxapol have not been completed, the Company has
not yet determined what adverse effects, if any, may be produced by tyloxapol at
the concentrations in which it will be present in the Company's SuperVent(TM)
product.
    

   CYSTIC FIBROSIS AND ITS PATHOLOGY

   
CF is a progressive, lethal respiratory disease that occurs in about one out of
every 2,000 live births in the United States and Europe. CF 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. A
revolutionary improvement in the medical management of CF has allowed most
patients with the disease to live until the age of 29. The progressive
destruction of CF lungs is the major
    

                                       21
<PAGE>
<PAGE>

impediment to even longer survival and improved health. 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.

   
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. Impacted mucus traps foreign particles and
pathogens and becomes a source of bacterial colonization, typically with
PSEUDOMONAS AERUGINOSA ("PSEUDOMONAS"). The patient's immune system responds to
the chronic infection by sending macrophages into the airways which recognize
and attempt to destroy the bacteria. These macrophages then recruit legions of
neutrophils to the lungs which activate the inflammatory transcriptional factor
Nuclear Factor-kappa B ("NF-[kappa]B") and initiate a cytokine-mediated
inflammatory response. The activated immune cells secrete inflammatory
cytokines, oxidative chemicals and destructive enzymes into the lungs. Repeated
inflammatory and oxidative processes initiated by macrophages and neutrophils to
clear the infection are typically ineffective and result in collateral damage to
the alveoli and small airways. Destroyed airway cells, neutrophils and
macrophages then spill their DNA and actin into the alveoli and markedly
increase the viscosity and adhesiveness of airway sputum. This debris-laden
mucus, rich in proteases and oxidants, causes the alveoli to collapse and are
then replaced with nonfunctional fibrous tissue. Eventually, a critical number
of alveoli, small airway cells and large airway cells are destroyed so that the
respiratory function of CF patients becomes insufficient to sustain life.
    

    CLINICAL DEVELOPMENT PLAN FOR SUPERVENT(TM) FOR CF

   
The Company's clinical development plan for SuperVent(TM) is to focus first on
CF, for which few safe and effective therapies exist. The Company has completed
a clinical research agreement with the University of Utah Health Sciences Center
("UHSC") and has commenced a clinical trial pursuant to such agreement. The
principal investigator of this clinical trial is Bruce C. Marshall, M.D.,
Director of the CF center of the UHSC. The co-investigators are John R. Hoidal,
M.D., Chief of the Pulmonary and Pediatric Pulmonary Divisions at UHSC, and
Wayne Samuelson, M.D., Director of the asthma center at UHSC. In September 1995,
the FDA approved, subject to certain modifications, Dr. Hoidal's
physician-sponsored Investigational New Drug ("IND") application to begin this
trial. The trial 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. The specific aims of the initial clinical study,
which is presently designed in three parts, are as follows:

      PART A.   A dose-ranging study will be performed in ten normal human
                volunteers receiving 4 ml of aerosolized SuperVent(TM) once
                daily to confirm a lack of airway toxicity and establish the
                safe inhaled concentration of SuperVent(TM). Assessment of 
                outcomes will include various measures of respiratory
                function.

      PART B.   An open study will be undertaken to establish the effects of
                aerosolized SuperVent(TM) airway physiology and lung
                inflammation in ten patients with cystic fibrosis. Patients will
                be followed for two weeks while receiving 4 ml of aerosolized
                SuperVent(TM) once daily. Assessment of outcomes will include 
                various measures of respiratory function.

      PART C.   In the format of a six-week, multi-center, randomized,
                double-blinded, placebo-controlled trial, 4 ml of aerosolized
                SuperVent(TM)once daily will be studied in up to 120 patients
                with cystic fibrosis with measures of outcome including
                respiratory function and
                physical exercise criteria.

The Company began the aforementioned Phase I/II clinical trial for the treatment
of CF on March 17, 1997 at UHSC. Assuming the successful completion of the Phase
I/II trial, the Company intends to commence a multi-center, randomized,
double-blinded, placebo-controlled, Phase III clinical trial in CF and to file
an additional IND to commence a Phase II clinical trial for the treatment of
chronic bronchitis.
    

    COLLABORATION WITH THE CYSTIC FIBROSIS FOUNDATION

The Company is collaborating with the Cystic Fibrosis Foundation in assembling a
CF medical advisory board to advise on the design of the Phase I/II clinical
trial in CF. The Cystic Fibrosis Foundation does not endorse investigational
drugs but does lend its support to companies conducting clinical trials in CF.
If successful in obtaining such support, the Company intends

                                       22
<PAGE>
<PAGE>

to utilize the assistance of the Cystic Fibrosis Foundation's patient registry
to coordinate a multi-center Phase III clinical trial. If the Phase III trial is
successful and regulatory approval to market SuperVent(TM) is obtained, the
Company plans to utilize the Cystic Fibrosis Foundation to distribute the
product in the United States and Canada.


CURRENT RESPIRATORY THERAPIES FOR CYSTIC FIBROSIS

    SUPPORTIVE CARE AND TRADITIONAL DRUG THERAPIES

The standard treatment for enhancing expectoration of CF sputum is postural
drainage and chest percussion. In this daily procedure, patients lie in an
inclined position with their head below their chest. The patient's chest is then
repeatedly and gently pounded for several minutes with a cupped hand by a care
giver. While modestly efficacious, postural drainage and chest percussion is
labor intensive and requires a care giver.

When mucus becomes colonized with bacteria such as PSEUDOMONAS and other
pathogens, a variety of intensive oral, intravenous and aerosolized antibiotics
are administered. Repeated use of these antibiotics to clear the infection often
results in strains of PSEUDOMONAS which are resistant to the antibiotics. Over
time, many CF patients become chronically colonized with drug resistant
PSEUDOMONAS. The ensuing cytokine-mediated inflammatory and oxidative process
then accelerates the destruction of the lungs.

    PULMOZYME(TM)

Standard daily pharmacologic therapy for airway obstruction in CF presently
consists largely of inhaled Pulmozyme(TM) (recombinant human rhDNase or dornase
alfa). This drug has been marketed by Genentech in the United States and Canada
since early 1994. Pulmozyme(TM) 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 drug provides a small improvement in lung function and a slight reduction in
the number of days requiring intravenous antibiotics for respiratory infections.
The approximate yearly cost of Pulmozyme(TM) treatment for an average patient is
$11,000. Genentech's 1995 sales of Pulmozyme(TM) are estimated to have been
approximately $110 million.

    LUNG TRANSPLANT

Lung transplantation is the final option for CF patients suffering from severely
compromised respiratory function. However, there is an extremely limited supply
of transplantable lungs and the operation is very costly. In addition, there is
an increased risk of death from such a major surgical procedure and a long and
painful recovery. Furthermore, patients who do recover must take
immunosuppressive drugs for the rest of their life to prevent organ rejection,
making them vulnerable to infections.

SUPERVENT(TM) FOR CHRONIC BRONCHITIS

Assuming the successful completion of the Phase I/II trial of SuperVent(TM) in
CF, the Company intends to file an IND to commence a Phase II clinical trial for
the use of SuperVent(TM) to treat chronic bronchitis. Chronic bronchitis is a
major medical problem that is characterized by inflammation of the airways
leading to cough and increased mucus production. The condition afflicts
approximately 14,000,000 patients in the United States. Two primary causes of
chronic bronchitis are habitual smoking and air pollution. Non-specific
irritants contained in cigarette smoke and air pollution result in an increased
number of macrophages entering into the lungs. The macrophages become activated
and secrete inflammatory cytokines which recruit neutrophils that together
release oxidants and elastase, an enzyme which degrades a structural component
of the lungs, elastin. These released oxidants and free radicals oxidize
alpha1-antitrypsin which normally inactivates elastase. In addition, elastin
repair may be inhibited by cigarette smoke leading to structural changes in the
lung that may significantly compromise respiratory function.

   
Based on clinical studies and other studies conducted by persons affiliated and
unaffiliated with the Company, the Company believes that high concentrations of
tyloxapol may improve pulmonary function in chronic bronchitis patients.
SuperVent's(TM) active compound , tyloxapol, is also a component of Exosurf(TM),
a product that has been clinically tested to treat chronic bronchitis. The
chemical composition of the Company's SuperVent(TM) product is substantially
different from that of Exosurf(TM). SuperVent(TM) contains a substantially
higher concentration of tyloxapol in a phosphate-
    
                                       23
<PAGE>
<PAGE>
   
buffered saline solution. Exosurf(TM) is composed of tyloxapol, cetyl alcohol,
dipalmetoylphosphatitylcholine and sodium chloride. Exosurf(TM), as prepared for
use in treating chronic bronchitis, was, to the Company's knowledge, difficult
to satisfactorily aerosolize. SuperVent(TM) can be aerosolized and successfully
delivered through a nebulizer.
    

HISTORY OF SAFE USE

   
Tyloxapol has been safely used by the pharmaceutical industry for over 40 years
as an emulsifying agent in various drug formulations containing concentrations
of tyloxapol lower than those intended to be present in the Company's
SuperVent(TM) product. Sterling Pharmaceuticals ("Sterling") previously marketed
in the United States a formulation containing low concentrations of tyloxapol
(0.125% by volume) as an expectorant for chronic bronchitis under the trade name
Alevaire(TM). Alevaire(TM) was first approved for use in the United States in
the late 1940's in children with pulmonary tuberculosis as an aerosol delivery
vehicle for streptomycin, an antibiotic. At that time, IN VITRO (i.e., non-
animal) studies indicated that sodium bicarbonate and tyloxapol increased
susceptibility of tuberculosis to streptomycin. Alevaire(TM) has been inhaled by
children with tuberculosis for two hours a day for up to six months without
adverse effects. In a group of adult tuberculosis patients, Alevaire's(TM)
expectorant properties were noted when it was reported that thick, viscous mucus
became thin and watery upon administration. Alevaire(TM) has been used as a
mucolytic treatment for a variety of respiratory conditions. Based on published
literature, Alevaire(TM) has no reported adverse effect on bacterial
host-defense mechanisms and has even been locally infused into humans to hasten
resolution of infected joints and pacemaker pockets.

Alevaire's(TM) marketing was discontinued by Sterling in 1981. At that time,
passage of the Harris-Kefauver amendment to the Food and Drug Act mandated that
older drugs previously approved only on the basis of safety, the regulatory
standard at the time, were required to demonstrate efficacy to continue to be
marketed. Because only anecdotal reports of efficacy and not controlled studies
were available to support Alevaire's(TM) use in respiratory diseases, it was
ruled that there was insufficient data to permit the product's continued use
without further studies. Sterling apparently elected to withdraw the drug from
the United States market, presumably because its patent had expired.
Alevaire(TM) is still marketed in Japan by Nippon Shoju Co., Ltd. At the present
time, tyloxapol, in addition to being used in the surfactant Exosurf(TM), is
included as an "inactive" ingredient in the over-the-counter medications Vicks
Sinex(TM) and Visex(TM), which are marketed by Procter & Gamble, Inc. A review
of the literature by the Company does not indicate that Alevaire(TM) was ever
tested as an anti-oxidant or used to treat CF.
    

MECHANISMS OF ACTION

    ANTI-INFLAMMATORY ACTIVITY

   
Experimental studies suggest that SuperVent(TM) is a potent inhibitor of the
inflammatory transcriptional factor NF-[kappa]B. Inhibition of NF-[kappa]B is an
area of intense pharmaceutical research as it is a central transcriptional
regulation element by which monocytes and macrophages regulate the expression of
multiple inflammatory cytokines and growth factors implicated in the destruction
of CF lungs. In preclinical studies, secretion of TNF-[alpha], IL-1(beta), IL-6,
IL-8 and GM-CSF by LPS-stimulated human monocytes was significantly (p <0.010)
decreased by tyloxapol in a dose-dependent manner.
    
    ANTI-OXIDANT ACTIVITY

   
IN VITRO and IN VIVO (i.e., animal) experimental studies conducted by the
Company's scientific founders suggest that SuperVent(TM) is a potent
anti-oxidant capable of scavenging injurious hydroxyl radicals and hypochlorous
acid. These toxic chemicals are produced in abundance by activated inflammatory
cells in the airway. Two IN VITRO models testing the oxidant scavenging activity
of tyloxapol showed that the addition of tyloxapol to the reaction mixture
inhibited oxidant generation in a concentration dependent manner. In an
additional IN VITRO model, tyloxapol was shown to be an effective oxidant
scavenger through its ability to prevent oxidant-mediated conversion of
diethanolamine to its corresponding chloramine. The Company's scientific
founders have further shown in an IN VIVO model that tyloxapol protects against
oxidant-mediated lung injury. Intratracheal instillation of oxidants in rats
caused acute lung injury as demonstrated by a marked increase in protein
concentration and neutrophil percentage in lung lavage fluid. Post-exposure
treatment with tyloxapol significantly reduced both lavage protein concentration
(p < 0.001) and neutrophil percentage (p < 0.010).

    MUCOLYTIC ACTIVITY

IN VITRO studies of the sputum from CF patients suggest that the surface tension
reducing properties of SuperVent(TM) may be an effective agent in decreasing
mucus adherence and facilitating expectoration. The Company believes that
SuperVent's(TM) ability to modify the biophysical properties of the abnormally
thick mucus in CF patients should, in concert with postural percussion and
drainage, offer respiratory benefit.

KL4-SURFACTANT TECHNOLOGY

    BACKGROUND

   
Lung surfactants are protein-phospholipid complexes which coat the alveoli (air
sacs) of the lungs. Alveoli are delicate, balloon-like sacs in the lungs where
gaseous exchange occurs. Lung surfactants lower surface tension in expiration
and raise it during inspiration to prevent the collapse of alveoli. Replacement
surfactants are currently used mainly to treat infant respiratory distress
syndrome ("IRDS"). Infants with this condition, as well as infants born with
meconium in their lungs, which can lead to meconium aspiration syndrome ("MAS"),
and patients with adult respiratory distress syndrome ("ARDS"), typically suffer
from insufficient surfactant that leads to a life-threatening loss of pulmonary
function.

KL4-Surfactant is a proprietary, synthetic lung surfactant that was originally
invented at The Scripps Research Institute ("Scripps") by Charles G. Cochrane,
M.D., et al. KL4-Surfactant is an aqueous suspension of lipid vesicles
containing the novel synthetic peptide KL4 (KLLLLKLLLLKLLLLK). The "K"
represents the water-soluble amino acid lysine and the "L" represents the
fat-soluble amino acid leucine. KL4-Surfactant is patterned after human
Surfactant Protein B, shown to have the greatest surfactant activity in humans .
Human Surfactant Protein B acts by forming a stable monolayer on the inner
surface of the pulmonary alveoli and preventing their collapse. The product was
exclusively licensed to Johnson & Johnson, Inc. ("J&J"), which led its
development from 1991 until its license to ATI. J&J completed a multi-center,
Phase II clinical trial of KL4-Surfactant in 47 infants with IRDS. This trial
demonstrated safety and efficacy comparable to that of the bovine-derived
surfactant, Survanta(TM), markete by Ross Laboratories.

Discovery's majority-owned subsidiary, ATI, has acquired the exclusive worldwide
sublicense to the KL4-Surfactant technology from J&J and J&J's wholly owned
subsidiary, Ortho Pharmaceutical Corporation ("Ortho"). The Company believes
that as a peptide-containing, synthetic lung surfactant, KL4-Surfactant will be
superior to the non- protein-containing surfactant, Exosurf(TM), marketed by
Glaxo-Wellcome. The Company further believes that KL4- Surfactant will be as
effective as or superior to the animal-derived, protein-containing surfactants,
Survanta(TM) (bovine-derived) and InfaSurf(TM) (calf-derived, being developed by
Forest Laboratories). In addition, the Company believes that synthetic
surfactants will be far less expensive to produce and will not have the
viral/prion (suspected to cause "Mad Cow Disease") contamination and
immunogenicity concerns associated with animal- derived proteins. The Company
further believes that a lower cost of production may make the use of lung
surfactants economically feasible for adult indications such as ARDS.
    

TARGET DISEASE INDICATIONS

The Company intends to initially develop the KL4-Surfactant technology for the
treatment of MAS and ARDS. The Company may also develop the KL4-Surfactant
technology for the treatment of IRDS.

    MECONIUM ASPIRATION SYNDROME.

MAS affects approximately 26,000 newborn infants per year in the United States
alone. The disease results from the release of meconium, a greenish, pasty
constituent of the fetal bowel, into the amniotic fluid. Meconium is then
aspirated into the fetal lungs. The presence of meconium in the infant's lung
after delivery often leads to pneumonitis, a generalized inflammation of the
lungs, which can result in death. This inflammation degrades lung surfactant and
results in insufficient pulmonary function. Presently, there are no products
specifically approved for this condition. Treatment consists of general
supportive care. Approximately one-third of the infants with MAS require
extra-corporeal membrane oxygenation therapy ("ECMO").

    ADULT RESPIRATORY DISTRESS SYNDROME.

                                       25
<PAGE>
<PAGE>

ARDS is a generalized inflammatory disease of the lungs marked by intense
leukocytic infiltration, edema and atelectasis (partial lung collapse).
Endogenous surfactant in the lung is degraded from this inflammatory cascade
leading to further loss of the epithelial cells that make surfactant. The
initiating factors of ARDS are numerous and include sepsis, head injury,
aspiration of gastric contents and other noxious fluids, trauma, smoke
inhalation and broken bones. Patients typically require mechanical ventilation
and are at risk of developing multiple organ failure. Mortality has remained at
approximately 50%. There is no FDA-approved therapy outside of general
supportive care. The incidence is approximately 150,000 patients per year in the
United States.

    INFANT RESPIRATORY DISTRESS SYNDROME.

   
IRDS is primarily a disease of premature infants. These infants are born prior
to the synthesis of adequate amounts of pulmonary surfactant proteins. The
disease affects 40,000 to 50,000 infants per year in the United States and an
equal number in Europe. Twenty to forty percent of infants with IRDS develop
debilitating bronchopulmonary dysplasia requiring extended ventilatory support
and hospitalization. The cost of caring for these infants can exceed $100,000
per patient. Therapy shortly after birth with animal-derived surfactants has
proven to be effective in liberating infants from mechanical ventilation or
abbreviating the period of ventilation. Surfactant therapy has reduced the
historical mortality rate by more than a half to about 10%.
    

COMPETITIVE ASSESSMENT

   
Presently, there are no approved drugs that are specifically indicated for MAS
or ARDS. Current therapy consists of general supportive care and mechanical
ventilation. Three products are specifically approved for the treatment of IRDS.
Exosurf(TM), which contains only phospholipids and synthetic organic detergents
and no stabilizing protein or peptides, is marketed by Glaxo Wellcome.
Survanta(TM), which has been shown to be more effective than Exosurf(TM) in
clinical trials, is an extract of bovine lung that contains the cow version of
Surfactant Protein B. Survanta(TM) is marketed by Ross Laboratories, a division
of Abbott Laboratories, a had estimated 1995 annual sales of approximately $60
million. Recently, Forest Laboratories obtained an approvable letter from the
FDA for its calf lung surfactant, Infasurf, for use in IRDS. Although none of
the three approved surfactants for IRDS is approved for ARDS, which is a
significantly larger market, there are a significant number of other potential
therapies in development for the treatment of ARDS that are not surfactant
related. Any of these various drugs or devices could significantly impact the
commercial opportunity for KL4-Surfactant.
    
DEVELOPMENT STATUS

    INFANT RESPIRATORY DISTRESS SYNDROME

   
In July 1992, an IND was submitted to the FDA by Charles G. Cochrane, M.D., of
Scripps, the inventor of KL4-Surfactant and a consultant to ATI. The IND sought
to evaluate the safety and efficacy of KL4-Surfactant in the treatment of IRDS.
A total of 47 infants with IRDS were treated with KL4-Surfactant in this
multi-center, Phase II clinical trial. The pulmonary function of the infants,
measured as a ratio (a/A) of arterial oxygen concentration (a) as a function of
the concentration of the inspired oxygen (A), averaged 0.14 (severe respiratory
distress) and rose to the normal range (>0.40) within 12 hours of treatment.
Airway pressures were reduced over this period and the infants were removed from
supportive mechanical ventilation in a mean time of five days. There were no
IRDS-related deaths in the trial.
    

    ADULT RESPIRATORY DISTRESS SYNDROME

   
Dr. Cochrane and his colleagues at Scripps have developed an adult animal model
of ARDS. In every case with this model, KL4-Surfactant treatment appeared to
re-expand the lungs and induce an elevation of arterial oxygen partial pressure
from <100 mmHg to > 400 mmHg within two hours. These experimental results
suggest that KL4-Surfactant has the potential to treat patients with this
life-threatening condition. In addition, pilot clinical studies on ARDS patients
conducted by researchers unaffiliated with the Company or its scientific
founders using animal-derived sufactants demonstrated safety and efficacy.
Scientists at Justus-Liebig University in Germany conducted a clinical study and
concluded that the bronchoscopic application
    

                                       26
<PAGE>
<PAGE>

   
of a high dose of surfactant, aimed at overcoming inhibitory factors in the
alveolar space of the patients, may offer a feasible and safe approach to
improving gas exchange in severe ARDS patients. The results of this study were
published during 1996 in the American Journal of Critical Care Medicine.
    
    MECONIUM ASPIRATION SYNDROME

Dr. Cochrane and his colleagues at Scripps have developed a potential method of
preventing MAS by lavaging meconium-filled lungs with diluted KL4-Surfactant. In
the lungs of adult rabbits and newborn rhesus monkeys, the lavage not only
removed much of the meconium, but it also immediately expanded the lungs and
allowed for greater respiration within minutes. The results of these
experimental studies suggest that prophylactic KL4-Surfactant administration has
the potential to eliminate MAS in newborn infants at risk of developing this
life-threatening condition.

INVESTMENT IN ACUTE THERAPEUTICS, INC.; LICENSE OF KL4-SURFACTANT TECHNOLOGY

   
On October 28, 1996, Discovery completed a transaction pursuant to which it
invested $7.5 million in a new majority-owned subsidiary, ATI, in exchange for
600,000 shares of Series A Convertible Preferred Stock of ATI, representing
75% of the outstanding voting securities of ATI following such transaction. 
Concurrent  with  Discovery's  investment in  ATI, J&J, Ortho and  ATI
entered into an agreement (the "J&J License Agreement") granting an exclusive
sublicense of the KL4-Surfactant technology to ATI in exchange for certain
license fees, royalties and 40,000 shares of Common Stock of ATI, representing
approximately 5% of the outstanding voting securities of ATI. J&J contributed
its existing KL4-Surfactant raw material inventory and specialized manufacturing
equipment, with an estimated original cost of $3.3 million, to ATI in exchange
for shares of nonvoting Series B Preferred Stock of ATI having a $2.2 million
liquidation preference. In exchange for its consent to the J&J License
Agreement, Scripps received shares of Common Stock of ATI comprising
approximately 5% of the outstanding voting securities of ATI.
    

Pursuant to agreements entered into by the founding management of ATI, members
of founding management were granted options to purchase an aggregate of 84,800
shares of Common Stock of ATI. Each founder was granted two options: a
Restricted Option and a Basic Option (each as defined below). The "Restricted
Options" cover an aggregate of 44,800 shares of Common Stock of ATI, at an
exercise price of $0.01 per share, and will be exercisable on the fifth
anniversary of the date of grant (or earlier upon the occurrence of an
Acceleration Event as defined below). An "Acceleration Event" includes any
equity financing of ATI, certain debt financings, or a merger or sale of
substantially all of the assets of ATI. If an Acceleration Event occurs prior to
the fifth anniversary of the grant date, the Restricted Options will be
exercisable based on the valuation of ATI in the Acceleration Event, as set
forth below:

   
          Valuation of ATI Following,                     Percentage of Total
       or Consideration Received in, the                   Restricted Option
             Acceleration Event                           Shares Accelerated
    
            Less than $65 million                                  0%
                Over $65 million                                  25%
                Over $75 million                                  50%
                Over $85 million                                  75%
                Over $95 million                                 100%

The "Basic Options" cover an aggregate of 40,000 shares of Common Stock of ATI
at an exercise price of $0.32 per share, and will become exercisable in full
upon the expiration of six months following the date of grant. However, in the
event that a founder's service terminates prior to the six month anniversary by
reason of death, permanent disability or termination for cause, the founder's
option shall accelerate and become exercisable as of the date of such
termination event.

In connection with Discovery's investment in ATI, all of the shareholders of ATI
entered into a Co-Sale Agreement. Under the terms of the Co-Sale Agreement, if a
shareholder of ATI proposes to sell any shares of stock of ATI (with certain
exceptions), each other shareholder has the right to participate PRO RATA in
such sale. The Co- Sale Agreement terminates upon the consummation of an
underwritten public offering of Common Stock of ATI, an acquisition of ATI or
certain insolvency proceedings.
    

DEVELOPMENT PLAN/SPONSORED RESEARCH AGREEMENT

   
ATI currently has an approved IND for ARDS. ATI intends to seek FDA approval to
amend the approved IND and to re-initiate Phase II clinical trials of
KL4-Surfactant for the treatment of ARDS in 1997. ATI has amended its existing
IRDS IND to permit the initiation of Phase II clinical trials in MAS. ATI met
with the FDA on March 10, 1997, to discuss its MAS development program. ATI
received constructive feedback from the FDA and intends to commence its MAS
development program on schedule. The Company has not had any discussions with
the FDA regarding clinical trials of KL4-Surfactant for the treatment of ARDS,
however, and there can be no assurance that approval to amend the ARDS IND will
be granted. Orphan drug status for MAS, ARDS and IRDS has been granted by the
FDA.

ATI and Scripps have entered into a sponsored research agreement (the "Sponsored
Research Agreement") supporting continuing research by Charles G. Cochrane,
M.D., and Susan Revak of Scripps. Pursuant to the Sponsored Research Agreement,
ATI will contribute $460,000 annually to Scripps' KL4-Surfactant research
efforts for an initial two-year period. ATI has an option to acquire an
exclusive worldwide license to make, have made, sell or use technology developed
under the agreement, which it is required to exercise within 180 days from
receipt of notice from Scripps of the development of such technology. Scripps
will own all technology that it develops pursuant to work performed under the
proposed Sponsored Research Agreement. ATI has the right to receive 50% of the
net royalty income received by Scripps for inventions jointly developed by ATI
and Scripps to the extent ATI does not exercise its option with respect to such
inventions.
    

ATI has entered into consulting agreements with certain key research personnel
at Scripps. See "Executive Compensation and Employment and Consulting
Agreements."

ST-630

    BACKGROUND

   
ST-630 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
about $750 million 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. The Company
believes that this risk of hypercalcemia may be the primary reason why active
vitamin D analogs have only been tested on a limited basis in the United States,
which is generally considered to be a high calcium consumption country.
No vitamin D analogs are currently marketed for osteoporosis in the United
States. Because the Company has not completed a Phase I clinical study of
ST-630, the Company has not yet determined whether ST-630 represents a risk of
hypercalcemia at any dosage levels that may prove efficacious for treating
postmenopausal osteoporosis.

The Company has a license agreement (the "WARF License Agreement") with the
Wisconsin Alumni Research Foundation ("WARF") relating to ST-630 and its use in
treating postmenopausal osteoporosis. The Company believes that ST-630 may have
an improved pharmacological profile compared to earlier, active vitamin D
analogs, although there can be no assurance of this. Sumitomo Pharmaceuticals
("Sumitomo") and Taisho Pharmaceuticals ("Taisho") have jointly licensed the
right to develop, manufacture and market ST-630 in Japan for the treatment of
osteoporosis and are presently conducting the equivalent of a Phase II clinical
study of this drug in Japan. The Company has access to the preclinical data
generated by Sumitomo and Taisho pursuant to the terms of the WARF License
Agreement. The Company intends to seek FDA approval to initiate a Phase I
clinical study of ST-630 as a once-daily, orally administered drug for the
treatment of osteoporosis in the
    

                                       28

United States. The Company has not had any discussions with the FDA
regarding ST-630, however, and there can be no assurance that such approval will
be granted. The Company believes that ST-630 could be administered in
combination with other approved drugs for osteoporosis. The composition of
matter patent covering ST-630 expires in 2001. A patent covering the use of
ST-630 to treat postmenopausal osteoporosis recently issued in the United
States. See "Patents, Licenses and Proprietary Rights."
    

    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. Typically, fractures occur in the weight-bearing bones of the
vertebrae and the hip. On average, women have 10% to 25% less bone mass than men
at maturity. When menopause occurs, the production of estrogen diminishes and
women experience accelerated bone loss. In the United States, 7 to 20 million
women are at risk for developing postmenopausal osteoporosis. In the context of
other diseases, a woman's risk of developing a hip fracture is equal to her
combined risk of developing breast, uterine and ovarian cancer. One out of every
five persons who has a hip fracture will not survive more than one year. In
addition, one-third of all patients with hip fractures will become totally
dependent and one-half will need assistance with walking. The annual cost of
acute care associated with osteoporosis in the United States is estimated to be
in excess of $10 billion.
    
    APPROVED THERAPIES FOR OSTEOPOROSIS

    ESTROGEN

   
Estrogen is of proven benefit in treating osteoporosis in postmenopausal women.
However, it is associated with significant adverse effects which limit its use
for osteoporosis. Estrogen replacement therapy for postmenopausal women can
cause hot flashes, menstruation (when taken with progesterone) and, more
seriously, may increase the risk of breast and uterine cancer. Extensive use of
Vitamin D analogs in Europe and Japan has not revealed any association of
Vitamin D analogs with any of these significant adverse side effects. Estrogen
must be continually taken or the accumulated bone mass is quickly lost.
    
    FOSAMAX(TM)

   
Fosamax(TM) or alendronate, from Merck, is the first approved osteoporosis drug
in the United States of the bisphosphonate class. (Bisphosphonates are
inhibitors of bone resorption mediated by a class of cells called osteoclasts.)
The drug is incorporated into bone and prevents calcium in bone from being
reabsorbed. While clinical studies have demonstrated increases in bone mass
leading to decreased hip and vertebral fractures when the drug is taken for
three years, the long-term safety questions of the drug, which is believed to
remain in the body for up to a decade are unknown. Many other bisphosphonates
are in late-stage clinical testing for osteoporosis. Fosamax(TM) has also been
associated with acute esophagitis in some patients. To limit the risk of
developing this painful and dangerous condition, patients must take the pill
upon awakening in the morning with a full glass of water, remain in a standing
position, avoid food for at least half an hour and then consume a full
breakfast. Vitamin D analogs have not been associated with acute esophagitis.
    
    NASAL CALCITONIN

   
Miacalcin(TM) as sold by Sandoz Pharmaceuticals is a nasally administered
calcitonin. While the injectable form of calcitonin has proven to be safe and
effective for reducing bone pain associated with vertebral fractures, the amount
of increase in bone mass is relatively modest. Miacalcin(TM) has never been
shown to decrease the risk of fractures.
    

    VITAMIN D AND CALCIUM SUPPLEMENTATION

Currently, vitamin D and calcium supplementation is being studied in a 45,000
patient Women's Health Initiative open label study. Given earlier, smaller
studies which have been completed, the Company believes that this study will
most likely confirm a modest benefit to increasing bone mass when administered
to younger women. Older women and men will probably not

                                       29
<PAGE>
<PAGE>

benefit from this therapy as it is thought that the kidney's ability to convert
vitamin D to the active form is compromised with age.

    THERAPIES IN DEVELOPMENT FOR OSTEOPOROSIS

    SLOW-RELEASE SODIUM FLUORIDE

   
Slow-release sodium fluoride is being developed by Mission Pharmacal. In a small
study, women on this compound increased bone in their hip and spine and had
fewer fractures. However, high doses of sodium fluoride, which had been
previously studied in a non slow-release formulation, caused peptic ulcers and
built brittle bone. Vitamin D analogs are not known to cause any of these side
effects. It is thought that patients taking sodium fluoride will need to be
monitored to ensure that their blood fluoride levels stay below toxic levels.
    

    SMALL MOLECULE ESTROGEN AGONISTS/ANTAGONISTS

   
Raloxifene (being developed by Eli Lilly) and droloxifene (being developed by
Pfizer) are small molecule estrogen agonists\antagonists which may offer
estrogen's therapeutic benefit to bone without increasing the risk of breast and
uterine cancer. The efficacy and adverse effect profile of these compounds in
comparison to estrogen are still being studied in late stage clinical trials.
    

DEVELOPMENT PLAN

   
The Company has access for regulatory purposes to preclinical data already
generated by Sumitomo and Taisho with respect to ST-630 pursuant to the terms of
the WARF License Agreement. See "Business--Products and Technologies Under
Development--Vitamin D Analog for Treatment of Osteoporosis--ST-630." The
Company intends to seek FDA approval to initiate clinical studies of ST-630 as a
once-daily, orally administered drug for the treatment of postmenopausal
osteoporosis in the United States. Following FDA clearance, if given, the
Company intends to conduct an initial dose-ranging study of ST-630 in humans.
Based upon the results of the dose-ranging study, the Company may then either
seek to further optimize the delivery of ST-630 by testing one or more
alternative means of delivery or, assuming acceptable results, seek to initiate
a large-scale clinical trial in the United States with effect on bone mineral
density being the primary endpoint. The Company has had no interaction with the
FDA to date regarding ST-630 and there can be no assurance that the Company's
planned clinical trial of ST-630 will receive the requisite regulatory
approvals.
    

GOVERNMENT REGULATION; ORPHAN DRUG DESIGNATION

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 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 I consists of testing the drug product in a small number of
humans to determine preliminary safety and tolerable dose range. Phase II
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
    
                                       30
<PAGE>
<PAGE>

   
and to identify possible common adverse effects in a larger group of subjects.
Phase III 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. NDAs submitted to the
FDA generally take 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. See
"Risk Factors--Extensive Government Regulation; Uncertainty of FDA and Other
Governmental Approval of Products Under Development."

In March 1995, the Company's scientific founders obtained from the FDA an orphan
drug designation for the use of tyloxapol to treat CF. In addition, orphan drug
status for the use of KL4-Surfactant to treat MAS, ARDS and IRDS has been
granted by the FDA. Under the Orphan Drug Act, the FDA may grant orphan drug
designation to drugs intended to treat a "rare disease or condition," which
generally is defined as a disease or condition that affects populations of fewer
than 200,000 individuals in the United States. If the Company is the first
sponsor to receive FDA approval to market tyloxapol to treat CF, or to market
KL4-Surfactant to treat MAS, ARDS or IRDS, the orphan drug designation will,
under current law, entitle the Company to a seven-year period of marketing
exclusivity in the United States during which the FDA, subject to certain
limitations, will not approve another application for the same drug for the same
indication. There can be no assurance that the Company will ever receive FDA
approval to market SuperVent(TM) to treat CF or to market KL4-Surfactant to
treat MAS, ARDS or IRDS, and thus there can be no assurance that the Company
will obtain the benefits of any of the aforementioned orphan drug designations.
While orphan drug designation and marketing approval may be advantageous to the
Company, if achieved, there can be no assurance that the scope of protection or
the level of exclusivity that is currently afforded by such designation and
approval will remain in effect in the future. In addition, competitors of the
Company may obtain orphan drug designation for product candidates that are not
the same as SuperVent(TM) or KL4-Surfactant though they are intended to treat
the same indications. The Company may request orphan drug designation, if
applicable, for more of its products or additional indications as part of its
overall regulatory strategy in the future.
    

PATENTS, LICENSES AND PROPRIETARY RIGHTS

The Company's success will depend in part on patent and trade secret protection
for its technologies, products and processes, and on its ability to operate
without infringing the proprietary rights of other parties both in the United
States and in foreign countries. Because of the substantial length of time and
expenses associated with bringing new products through development to the
marketplace, the pharmaceutical industry places considerable importance on
obtaining and maintaining patent and trade secret protection for new
technologies, products and processes. The failure to obtain and maintain patent
protection could mean that the Company would face increased competition in the
United States and in foreign countries.

LICENSING ARRANGEMENTS

    CMHA LICENSE AGREEMENT:  SUPERVENT(TM)/TYLOXAPOL

                                       31
<PAGE>
<PAGE>
   
The Company depends on its license with CMHA (the "CMHA License Agreement") for
the core technology relating to its SuperVent(TM) product under development. The
CMHA License Agreement grants the Company an exclusive worldwide license
(including the right to sublicense) to develop, make and sell products which are
covered in whole or in part by a valid claim contained in the two issued United
States patents (United States Patent No. 5,474,760 issued December 12, 1995 and
United States Patent No. 5,512,270 issued April 30, 1996) and two pending United
States patent applications held by CMHA and licensed to the Company under the
CMHA License Agreement, and any later-issued United States and any foreign
patents based on or issuing from the issued patents and the pending patent
applications. The United States patents cover methods of using tyloxapol, the
active compound in SuperVent(TM), to treat cystic fibrosis and methods of
treating disease 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. Two
international applications have been filed under the Patent Cooperation Treaty,
and certain corresponding foreign national applications are pending. These
applications claim, INTER ALIA, the use of tyloxapol to treat cystic fibrosis
and the use of tyloxapol as an anti-oxidant and anti-inflammatory agent. CMHA's
United States patents expire in 2013. The CMHA License Agreement is terminable
by CMHA: (i) on 60 days' prior notice upon the Company's failure to make timely
payments, reimbursements or reports, if the failure is not cured by the Company
within 60 days, or (ii) on 90 days' prior notice upon any material breach or
default by the Company, if the default or breach is not cured by the Company
within 90 days. The termination of the CMHA License Agreement, or the failure to
obtain and maintain patent protection for the Company's technologies, would have
a material adverse effect on the Company's business, financial condition and
results of operations.

In consideration of the license granted to the Company by CMHA, the Company (i)
has agreed to pay CMHA (a) royalties on net sales by the Company and by any
sublicensees of the Company of products covered by the licensed technology, and
(b) a percentage of any sublicense fees or similar amounts (other than research
and development payments) paid to the Company by any sublicensees, and (ii) is
responsible for the cost of filing and prosecuting patent applications and
maintaining issued patents. The CMHA License Agreement will terminate upon the
expiration of the last to expire of the licensed patents.
    

    J&J LICENSE AGREEMENT:  KL4-SURFACTANT

   
Pursuant to the J&J License Agreement, ATI has received an exclusive, worldwide
license to commercialize KL4-Surfactant and the other licensed technology for
the diagnosis, prevention or treatment of disease, including the right to
further sublicense such technology. The exclusive license granted to ATI is a
sublicense under certain patent rights previously licensed to J&J by Scripps
(the "Scripps Patent Rights") and a license under certain other patent rights
held by J&J's Ortho division (the "Ortho Patent Rights" and, together with the
Scripps Patent Rights, the "KL4 Patent Rights"). In addition to granting an
exclusive sublicense to ATI, J&J has transferred its existing KL4-Surfactant raw
material inventory and specialized manufacturing equipment to ATI in exchange
for Non-Voting Series B Preferred Stock of ATI.
    

ATI paid a $200,000 license fee to J&J upon execution of the J&J License
Agreement. In addition, ATI will pay J&J a royalty on net sales of
KL4-Surfactant sold by it or its sublicensees. The J&J License Agreement further
provides for the making of milestone payments as follows: $250,000 upon the
filing of the first New Drug Application ("NDA") for a product in a neonatal
indication; $500,000 upon approval of the first NDA for a product in a neonatal
indication; $500,000 upon filing of the first NDA for a product in the ARDS
indication; and $1,500,000 upon approval of the first NDA for a product in the
ARDS indication. Royalties are payable for a minimum period of ten years from
the first commercial sale of a product in each country and, thereafter (if
applicable) until expiration of the last to expire of the KL4 Patent Rights in
such country, after which time ATI will have a fully paid license.

   
The Scripps Patent Rights consist of three issued United States patents and two
pending United States applications. The three issued patents are United States
Patent No. 5,407,914, issued April 18, 1995; U.S. Patent No. 5,260,273, issued
November 9, 1993; and U.S. Patent No. 5,164,369, issued November 17, 1992. These
patents relate to synthetic pulmonary surfactants (including KL4-Surfactant),
certain related polypeptides and a method of treating respiratory distress
syndrome with these surfactants. The first of these patents will expire in 2009.
The two pending United States applications relate to pulmonary surfactants,
related polypeptides, liposomal surfactant compositions and methods of treating
respiratory distress syndromes with these surfactants and compositions.
Corresponding foreign patent applications are pending in the European Patent
Office, certain European countries, Canada and Japan. Two patents have issued in
Australia and one patent has issued in Norway. The Company believes that the
respiratory distress syndromes covered by these patents and patent applications
include MAS,
    

                                       32

<PAGE>

ARDS and IRDS. Scripps is responsible for filing, prosecuting and maintaining
the Scripps Patent Rights and J&J is required to reimburse Scripps for the costs
of such filings, prosecution and maintenance. The Ortho Patent Rights consist of
certain pending United States patent applications which relate to methods of
manufacturing certain peptides which may be used in the manufacture of
KL4-Surfactant. J&J is responsible for filing, prosecuting and maintaining the
Ortho Patent Rights.

    WARF LICENSE AGREEMENT:  ST-630

   
Pursuant to the WARF License Agreement, the Company has an exclusive license
within all countries in the Western hemisphere, including the right to
sublicense, in the field of prevention, treatment, amelioration or cure of bone
disease, under U.S. Patent No. 4,358,406 (the "ST-630 Patent") covering the
compound ST-630 and U.S. Patent No. 5,571,802 covering a method for treating
postmenopausal osteoporosis (the "ST-630 Use Patent"). In addition, the Company
has an option to extend the exclusive license to the remaining countries of the
world with the exception of Japan. The Company's option expires on January 1,
2002 and, with respect to Argentina, Spain, Portugal and Korea, must be
exercised prior to the commencement of product development therein.

The Company paid a one-time fee of $400,000 to WARF upon execution of the WARF
License Agreement. The Company is obligated to pay WARF a royalty on net sales
of ST-630 sold by it or its sublicensees in the licensed territories. In
addition, the Company is obligated to pay WARF a percentage of its income from
sublicensees. The WARF License Agreement also provides for the making of the
following milestone and option payments:

    For the exclusive license to the Western hemisphere: $150,000 upon
    completion of Phase II studies in the United States; and $1 million upon NDA
    submission in the United States. For the option for an exclusive license to
    Belgium, France, Germany, Italy, the Netherlands, Switzerland and the United
    Kingdom: $200,000 upon exercise of the Company's option and $1 million upon
    the first submission of an NDA with any European country. For the option for
    an exclusive license for the remaining countries of the world (other than
    Argentina, Spain, Portugal, Korea and Japan): $500,000 upon exercise of the
    Company's option. For the option for an exclusive license for Argentina,
    $10,000; for Spain, $170,000; for Portugal, $50,000; and for Korea, $15,000,
    in each case upon exercise of the Company's option. Each such option must be
    exercised no later than January 1, 2002.
    

To maintain the license, the Company is required to pay minimum royalties of
$100,000 per year beginning in calendar year 2002. The WARF License Agreement
shall remain in effect and royalties shall be payable for a period of fifteen
years from the date approval is received in the United States for the sale of
ST-630, after which time the Company shall have a fully paid license.

So long as the WARF License Agreement remains in effect, WARF is prohibited from
granting a license to any other party (other than in Japan) with respect to
ST-630 or certain proprietary information relating thereto for any indication,
with the exception of WARF's existing license agreement with Penederm, Inc.

   
The ST-630 Patent will expire in July 2001, which the Company anticipates will
be prior to receipt of any marketing approval for ST-630 in the United States .
The ST-630 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 ST-630. These claims do not include claims relating
to the use of ST-630 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 recently filed an application to
pursue additional claims relating to the use of ST-630 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.

Foreign patent applications corresponding to the ST-630 Patent and/or the ST-630
Use Patent have also been filed in certain countries, and such applications and
any resulting patents are licensed to the Company under the WARF License
Agreement. 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.
    

UNCERTAINTY OF BIOTECHNOLOGY PATENTS

                                       33
<PAGE>
<PAGE>

   
The patent position of firms relying upon biotechnologies 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 patent
application and issuance process can be expected to take several years and could
entail considerable expense to the Company. There can be no assurance that
patents will issue as a result of any applications filed or that the existing
patents or patents issued from existing applications will be sufficiently broad
to afford protection against competitors with similar technology. In addition,
there can be no assurance that such patents will not be challenged, invalidated
or circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company. The commercial success of the Company will also
depend upon its avoidance of infringement of patents issued to competitors. A
United States patent application is maintained under conditions of
confidentiality while the application is pending, so the Company cannot
determine the inventions being claimed in pending patent applications filed by
third parties. Litigation may be necessary to defend or enforce the Company's
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, even in those instances in which the outcome is
favorable to the Company, and can result in the diversion of substantial
resources from the Company's other activities. An adverse outcome could subject
the Company to significant liabilities to third parties, require the Company to
obtain licenses from third parties, or require the Company to alter its products
or processes, or cease altogether any related research and development
activities or product sales, any of which may have a material adverse effect on
the Company's business, financial condition and results of operations.

Tyloxapol, the active compound in SuperVent(TM), was the subject of an issued
U.S. 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.
    

CONFIDENTIALITY; ASSIGNMENT OF INVENTIONS

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. To the extent that consultants, key employees, or other
third parties apply technological information independently developed by them or
by others to any of the proposed projects of the Company, disputes may arise as
to the proprietary rights to such information which may not be resolved in favor
of the Company. In addition, the Company also relies on trade secrets and
proprietary know-how, that it seeks to protect in part by its confidentiality
agreements with its employees, consultants, advisors or others. There can be no
assurance that these agreements will not be breached, that the Company would
obtain adequate remedies for any breach, or that such trade secrets or
proprietary know-how will not otherwise become known or be independently
developed by competitors in such a manner that the Company has no legal
recourse.

THIRD PARTY SUPPLIERS

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 the Company'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.

                                       34
<PAGE>
<PAGE>

   
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. Although Sanofi has sold a
quantity of tyloxapol sufficient for the Company's proposed Phase I/II clinical
trial of SuperVent(TM), the Company does not presently have an agreement with
Sanofi to supply any additional material, either in connection with a Phase III
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 III
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 has entered
into an agreement with Cook Imaging Corporation for the packaging and storage,
under sterile and stable conditions, of purchased tyloxapol.

The Company is in negotiations with Tetrionics, Inc. ("Tetrionics") to
manufacture, formulate and supply the Company with GMP-grade ST-630 for the
Company's investigational and commercial purposes. Tetrionics presently
manufactures and supplies ST-630 to Penederm Inc. in the United States for
investigational topical use for the treatment of psoriasis. There can be no
assurance that the Company will be able to reach agreement with this proposed
manufacturer on terms acceptable to the Company, if at all. Any failure to
achieve agreement may substantially delay the Company's development of ST-630.
    

MARKETING AND SALES

   
It is the Company's long-term goal to market SuperVent(TM) for CF and possibly
certain of its other products through a direct sales force (or, in the case of
CF, possibly through the distribution capabilities of the Cystic Fibrosis
Foundation), if and when any necessary regulatory approvals are obtained.
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.
    

EMPLOYEES

   
The Company utilizes a product development strategy that involves contracting
out research, development and manufacturing functions to third parties in order
to minimize the expense and overhead associated with full-time employees.
Consistent with this strategy, Discovery has only nine employees. James S. Kuo,
M.D., joined Discovery in April 1996 as President, Chief Executive Officer and a
Director. David R. Crockford joined Discovery in November 1996 as Vice President
of Regulatory Affairs. Saul S. Bodenheimer, M.D., joined Discovery in December
1996 as Vice President of Clinical Affairs. Evan Myrianthopoulos joined

his time to the business of the Company. Steve Birnbaum joined Discovery in
November 1996 as the Project Manager for the ST-630 program. Discovery employs
two other full-time employees and two employees who devote only a portion of
their time to the business of the Company: Steve H. Kanzer, C.P.A., Esq., the
Company's Chairman, and Kenneth Johnson, the Company's Director of Business
Development. ATI has only eight employees. Robert J. Capetola, Ph. D., joined
ATI in October 1996 as President, Chief Executive Officer and Chairman of the
Board. Thomas E. Wiswell, M.D. joined ATI as Vice President of Clinical Research
in September 1996. Harry G. Brittain, Ph.D., joined ATI as Vice President of
Pharmaceutical and Chemical Development in November 1996. Laurence B. Katz,
Ph.D., joined ATI as Vice President of Project Management and Clinical
Administration in November 1996. Christopher J. Schaber joined ATI as Vice
President of Regulatory Affairs and Quality Assurance in November 1996. ATI
employs three other full-time employees, including Huei Tsai, Ph.D., who joined
ATI as Vice President of Biometrics in February 1997, and Lisa Mastroianni, who
joined ATI as Director of Clinical Research in February 1997. See "Risk

All directors hold office until the next annual meeting of stockholders of

of Directors. The Bylaws of each of Discovery and ATI provide that directors and
officers shall be indemnified against liabilities arising from their service as
directors or officers to the fullest extent permitted by the laws of the State
of Delaware, which generally requires that the individual act in good faith and
in a manner he or she reasonably believes to be in or not opposed to the best
interests of Discovery or ATI, as the case may be. Insofar as indemnification
for liabilities arising under the Securities Act of 1933

(THE "SECURITIES ACT") MAY BE PERMITTED TO DIRECTORS, OFFICERS AND CONTROLLING
PERSONS OF THE COMPANY PURSUANT TO THE FOREGOING PROVISIONS, OR OTHERWISE, THE
COMPANY HAS BEEN ADVISED THAT IN THE OPINION OF THE SECURITIES AND EXCHANGE
COMMISSION SUCH INDEMNIFICATION IS AGAINST PUBLIC POLICY AS EXPRESSED IN THE
SECURITIES ACT AND IS, THEREFORE, UNENFORCEABLE. IN THE EVENT THAT A CLAIM FOR
INDEMNIFICATION AGAINST SUCH LIABILITIES (OTHER THAN THE PAYMENT BY THE COMPANY
OF EXPENSES INCURRED OR PAID BY A DIRECTOR, OFFICER OR CONTROLLING PERSON OF THE
COMPANY IN THE SUCCESSFUL DEFENSE OF ANY ACTION, SUIT OR PROCEEDING) IS ASSERTED
BY SUCH DIRECTOR, OFFICER OR CONTROLLING PERSON IN CONNECTION WITH THE
SECURITIES BEING REGISTERED HEREBY, THE COMPANY 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 POLICY AS
EXPRESSED IN THE SECURITIES ACT AND WILL BE GOVERNED BY THE FINAL ADJUDICATION
OF SUCH ISSUE.

The Company has 17 employees. Two employees, Messrs. Kanzer and Johnson,
currently devote only a portion of their time to the Company. Certain of the
officers and directors of the Company currently do and may from time to time in
the future serve as officers or directors of other biopharmaceutical or
biotechnical companies. There can be no assurance that such other companies will
not in the future have interests in conflict with those of the Company. See
"Risk Factors--No Assurance of Additional Products; Risks Associated with
Products in Development" and "--Certain Interlocking Relationships; Potential
Conflicts of Interest."

DISCOVERY OPTION PLAN

Discovery has adopted the 1996 Stock Option/Stock Issuance Plan consisting of a
Discretionary Option Grant Program for employees, a Stock Issuance Program for
employees and an Automatic Option Grant Program under which option grants will
automatically be made at periodic intervals to eligible non-employee directors
to purchase shares of Common Stock. The exercise price under options issued
pursuant to the Discretionary Option Grant Program and the Automatic Option
Grant Program shall equal at least 85% of the fair market value of the Common
Stock on the grant date (and, in the case of incentive stock options, 100%).
Under the Discretionary Option Grant Program, options will be granted to
employees either as incentive stock options or non-statutory options and will
vest over a specified period of time (generally three to five years) as
determined by the Discovery Board of Directors. Discovery has reserved 1,125,000
shares for issuance under these plans.

Under the Stock Issuance Program, shares of Common Stock may be issued directly
without any intervening option grant in consideration for cash or past services
rendered to Discovery (or any parent or subsidiary of Discovery). Shares of
Common Stock issued under the Stock Issuance program may vest immediately or may
vest in one or more installments or upon the recipient's attainment of specified
performance objectives. Unvested shares held by the grantee may be canceled (or,
if issued for cash, repurchased at their original purchase price) in the event
the recipient ceases to remain in the service of Discovery or fails to attain
specified performance objectives.
   
Under the Automatic Option Grant Program, each non-employee director of
Discovery will automatically be granted an option for 25,000 shares of Common
Stock on the date of his or her election or appointment to the Board of
Directors, and each eligible non-employee director who is to continue to serve
as a director shall be granted an option to purchase an additional 10,000 shares
of Common Stock on the date of each annual meeting of stockholders (provided
such eligible non-employee director has served for at least 6 months). Such
options shall vest over four years. Each option will have a term of ten years,
subject to earlier termination following the optionee's cessation of service
on the Board of Directors. Each option will be immediately exercisable; however,
any shares purchased upon exercise of the option will be subject to repurchase
should the optionee's service as a non-employee director cease prior to vesting
of the shares.
    
Should Discovery be acquired by merger or asset sale or should there occur a
hostile change in control or ownership of Discovery, each outstanding stock
option will immediately vest in full either at the time of such acquisition or
hostile take-over (subject to certain exceptions) or upon the subsequent
termination of the individual's service with Discovery.

should the optionee's service as a non-employee director cease prior to vesting
of the shares. Each automatic share grant will vest in successive equal annual
installments over a three-year period.

The Company expects that its MAB's and SAB's will meet as a board with
management and key scientific employees and consultants of the Company, as
applicable, on a semi-annual basis and in smaller groups or individually from
time to time on an informal basis. The Company anticipates that MAB and SAB
members will review and provide advice to management on clinical trial design,
scientific planning and research and development. The Company expects that in
the future it will compensate certain of its medical advisors on a per-meeting
basis and/or through the granting of stock options.
   
MAB and SAB members may be employed by or have consulting agreements with
entities other than the Company, some of which may conflict or compete with the
Company, or which may limit a particular member's availability to the Company.
Certain of the institutions with which MAB and SAB members are affiliated may
have regulations or policies which are unclear with respect to the ability of
such personnel to act as part-time consultants or in other capacities for a
commercial enterprise. Regulations or policies now in effect or adopted in the
future might limit the ability of MAB and SAB members to consult with the
Company. The loss of the services of MAB or SAB members could have a material
adverse effect on the Company.
    
Although each current MAB and SAB member has the customary contractual
obligation to keep confidential and not to disclose nor use any confidential or
proprietary information of the Company, inventions or processes discovered by
any MAB or SAB member, unless otherwise agreed, will not become the property of
the Company but will remain the property of such

person or of such person's full-time employers. In addition, the institutions
with which the MAB and SAB members are affiliated may make available the
research services of their scientific and other skilled personnel, including the
MAB and SAB members to entities other than the Company. In rendering such
services, such institutions may be obligated to assign or license to a
competitor of the Company patents and other proprietary information which may
result from such services, including research performed by an advisor or
consultant for a competitor of the Company.

                              CERTAIN TRANSACTIONS

Pursuant to a private offering held during June through November 1996, the
Company consummated an offering of Units consisting of Series A Preferred Stock
and Common Stock (the "Unit Offering") pursuant to which the Company raised
aggregate gross proceeds of approximately $22,002,550. In connection with
services rendered by Paramount as placement agent for the Unit Offering, and
pursuant to a placement agency agreement entered into by the Company and
Paramount, the Company paid Paramount cash commissions of approximately
$1,980,230, a non-accountable expense allowance of approximately $880,102 and
placement warrants to acquire 220,026 shares of Series A Preferred Stock,
exercisable until November 8, 2006 at an exercise price of $11 per share of
Series A Preferred Stock and 220,026 shares of Common Stock, exercisable until
November 8, 2006 at an exercise price of $0.25 per share. See "Description of
Securities--Placement Agent Warrants."

Pursuant to such placement agency agreement, on November 7, 1996, the Company
and Paramount entered into a Financial Advisory Agreement, pursuant to which
Paramount will act as the Company's financial advisor. Such engagement provides
that Paramount will receive a monthly retainer of $4,000 per month for a minimum
of 24 months, plus expenses and success fees.

The Company has agreed to indemnify Paramount and certain related parties with
respect to liabilities arising out of the Unit Offering under the Federal
securities laws pursuant to the Placement Agency Agreement entered into by the
Company and Paramount. The Company has also agreed to indemnify Paramount and
certain related parties with respect to liabilities arising out of services
rendered pursuant to the Financial Advisory Agreement.

Common Stock to RAQ, LLC for $0.002 per share. Dr. Rosenwald is the Chief
Executive Officer of RAQ, LLC. During 1995 and the first quarter of 1996, Dr.
Rosenwald provided loans to the Company in the aggregate amount of $17,794, the
proceeds of which were used for salary and administrative purposes. Dr.
Rosenwald contributed such loans to the capital of the Company prior to the
initiation of the Unit Offering. Dr. Rosenwald had guaranteed a credit facility
provided by Fleet Bank in favor of the Company in an amount up to $350,000. The
proceeds of these loans were used by the Company in connection with its entry
into the CMHA License Agreement and for general operating and working capital
purposes. The outstanding balance of such loans, $201,000, was repaid in
September 1996 using a portion of the proceeds of the Unit Offering.

                            DESCRIPTION OF SECURITIES

The Company is authorized to issue up to 50,000,000 shares of Common Stock, par
value $0.001 per share, and 10,000,000 shares of Preferred Stock, par value,
$0.001 per share. As of January 2, 1997, 6,712,256 shares of Common Stock and
2,200,256 shares of Series A Preferred Stock were issued and outstanding.

COMMON STOCK

Each holder of Common Stock is entitled to one vote for each share held of
record. There is no right to cumulative voting of shares for the election of
Directors. The shares of Common Stock are not entitled to preemptive rights and
are not subject to redemption or assessment. Subject to the rights of holders of
Preferred Stock of the Company, each share of Common Stock is entitled to share
ratably in distributions to stockholders and to receive ratably such dividends
as may be declared by the Board of Directors out of funds legally available
therefor. Subject to the rights of holders of Preferred Stock of the Company,
upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive, pro-rata, the assets of the Company which
are legally available for distribution to stockholders. The issued and
outstanding shares of Common Stock are validly issued, fully paid and
non-assessable.

PREFERRED STOCK

The preferred stock of the Company can be issued in one or more series as may be
determined from time-to-time by the Board of Directors. In establishing a
series, the Board of Directors shall give to it a distinctive designation so as
to distinguish it from the shares of all other series and classes, and shall fix
the number of shares in such series and the preferences, rights and restrictions
thereof. All shares of any one series shall be alike in every particular. The
Board of Directors has the authority, without stockholder approval, to fix the
rights, preferences, privileges and restrictions of any series of preferred
stock including, without limitation: (a) the rate of distribution; (b) the price
at which and the terms and conditions on which shares shall be redeemed; (c) the
amount payable upon shares for distributions of any kind; (d) sinking fund
provisions for the redemption of shares; (e) the terms and conditions on which
shares may be converted if the shares of any series are issued with the
privilege of conversion; and (f) voting rights except as limited by law.

Although the Company currently does not have any fixed plans to designate any
series of preferred stock other than the Series A Preferred Stock or to issue
additional shares of preferred stock other than the shares of Series A Preferred
Stock issuable upon exercise of the Preferred Placement Warrants, there can be
no assurance that the Company will not do so in the future. As a result, the
Company could authorize the issuance of a series of preferred stock which would
grant to holders preferred rights to the assets of the Company upon liquidation,
the right to receive dividend coupons before dividends would be declared to
holders of Common Stock, and the right to the redemption of such shares,
together with a premium, prior to the redemption of Common Stock. The current
stockholders of the Company have no redemption rights. In addition, the Board of
Directors could issue large blocks of voting stock to fend off unwanted tender
offers or hostile takeovers without further stockholder approval.

SERIES A PREFERRED STOCK

The following is a brief summary of certain provisions of the Series A Preferred
Stock, but this summary does not purport to be complete and is qualified in all
respects by reference to the actual text of the Certificate of Designations for
the Series A Preferred Stock, a copy of which has been included as an Exhibit to
the Registration Statement and is incorporated herein by reference.

The Board of Directors of the Company has authorized the issuance of up to
7,000,000 shares of Series A Preferred Stock, the rights, preferences and
characteristics of which are as follows:

    DIVIDENDS

The holders of Series A Preferred Stock will be entitled to receive dividends
if, as and when declared by the Board of Directors of the Company out of funds
legally available therefor. No dividend or distribution, as the case may be,
will be declared or paid on any junior stock (including the Common Stock) unless
the dividend also is paid to holders of the Series A Preferred Stock. The
Company does not intend to pay cash dividends on the Series A Preferred Stock or
the underlying Common Stock for the foreseeable future.


                                       53

<PAGE>


    CONVERSION

Each share of Series A Preferred Stock may be converted, in whole or in part, at
the option of the holder at any time after the initial issuance date into four
shares of Common Stock based upon an initial conversion price equal to $2.50 per
share of Common Stock (the "Preferred Conversion Price"). The Preferred
Conversion Price is subject to adjustment upon the occurrence of certain
mergers, reorganizations, consolidations, reclassifications, stock dividends or
stock splits that will result in an increase or decrease in the number of shares
of Common Stock outstanding. In addition, the Preferred Conversion Price is
subject to adjustment on the date which is 12 months after the first date on
which shares of the capital stock (or securities received in exchange for the
capital stock) are traded on a national securities exchange for the capital
stock, or are quoted on the National Association of Securities Dealers Automated
Quotation System, the OTC Electronic Bulletin Board or the "Pink Sheets," (the
"Reset Date") if the average closing bid trading price of the Common Stock for
the 30 consecutive trading days immediately preceding the Reset Date (the
"Twelve Month Trading Price") is less than 135% of the then applicable Preferred
Conversion Price ("Reset Event"). Upon the occurrence of a Reset Event, the then
applicable Preferred Conversion Price will be reduced to equal the greater of
(i) the Twelve Month Trading Price divided by 1.35 and (ii) 50% of the then
applicable Preferred Conversion Price.

    MANDATORY CONVERSION

The Company has the right at any time after the Reset Date to cause the Series A
Preferred Stock to be converted in whole or in part, on a PRO RATA basis, into
shares of Common Stock at the applicable Preferred Conversion Price if the
closing price of the Common Stock exceeds 150% of the then applicable Preferred
Conversion Price for at least 20 trading days in any 30 consecutive trading day
period.

    LIQUIDATION PREFERENCE

Upon a (i) liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, (ii) sale or other disposition of all or substantially
all of the assets of the Company or (iii) merger or consolidation in which the
Company is not the surviving entity and voting power of the Company's
stockholders after such transaction is less than 50% (a "Merger Transaction")
((i), (ii) and (iii) being collectively referred to as a "Liquidation Event"),
after payment or provision for payment of the debts and other liabilities of the
Company, the holders of the Series A Preferred Stock then outstanding will first
be entitled to receive, PRO RATA, and in preference to the holders of the Common
Stock and any other series of Preferred Stock of the Company, an amount per
share equal to $13.50, subject to adjustment, plus accrued but unpaid dividends,
if any; PROVIDED, HOWEVER, that in the case of a Merger Transaction, such $13.50
per share may be paid in cash and/or securities of the surviving entity in such
Merger Transaction.

    VOTING RIGHTS

The holders of the Series A Preferred Stock have the right at all meetings of
stockholders to the number of votes equal to the number of shares of Common
Stock issuable upon conversion of the Series A Preferred Stock at the record
date for determination of the stockholders entitled to vote. So long as a
majority of the shares of Series A Preferred Stock remain outstanding, the
holders of 66.67% of the Series A Preferred Stock are required to approve (i)
the issuance of any securities of the Company senior to or on parity with the
Series A Preferred Stock, (ii) any material alteration or change in the rights
or preferences or privileges of the Series A Preferred Stock and (iii) the
declaration or payment of any dividend on any junior stock or the repurchase of
any securities of the Company. Except as provided above or as required by
applicable law, the holders of the Series A Preferred Stock, other than in
connection with vesting provisions of employee and consultant agreements, vote
together with the holders of the Common Stock and not as a separate class.

    LOCK-UP AND BLACKOUT PERIODS

The holders of shares of Common Stock issuable upon conversion of shares of
Series A Preferred Stock (the "Conversion Shares") have agreed pursuant to their
subscription agreements with the Company executed in connection with the Unit
Offering not to offer, pledge, sell, contract to sell, grant any option for the
sale of, or otherwise dispose of, directly or indirectly, any Conversion Shares,
without the prior written consent of Paramount. Such restrictions apply until
(i) three months after the first date on which the shares of Common Stock become
publicly traded (the "Initial Trading Date") with respect to 100% of each of the
holders' Conversion Shares, (ii) six months after the Initial Trading Date with
respect to 75% of such Conversion Shares, (iii) nine months after the Initial
Trading Date with respect to 50% of such Conversion Shares, and (iv) 12 months
after the Initial Trading Date with respect to the remaining 25% of such
Conversion Shares.


                                       54
<PAGE>
<PAGE>



The holders of Series A Preferred Stock issuable upon exercise of the Preferred
Placement Warrants and the Common Stock issuable upon conversion thereof
(collectively, the "Placement Conversion Shares") are bound, pursuant to the
terms of such Preferred Placement Warrants, not to offer, pledge, sell, contract
to sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, any of the Placement Conversion Shares prior to 12 months after the
initial trading date of such Placement Conversion Shares.

In addition, any shares of Common Stock issuable upon conversion of the Series A
Preferred Stock shall be subject to a blackout period with respect to the
Registration Statement for the following periods: (i) any period not to exceed
two 30-day periods within any one 12-month period the Company requires in
connection with a primary underwritten offering of equity securities and (ii)
any period, not to exceed a 60-day period per circumstance or development, when
the Company determines in good faith that offers and sales pursuant thereto
should not be made by reason of the presence of material undisclosed
circumstances or developments with respect to which the disclosure that would be
required in such a prospectus is premature, would have a material adverse effect
on the Company or is otherwise inadvisable.

STOCK OPTIONS
   
A total of 1,250,000 shares of Common Stock has been reserved for issuance
under the Company's 1996 Stock Option Plan (the "Option Plan"). The Option Plan
was adopted by the Board of Directors in October 1996. The Option Plan expires
by its own terms in 2006. See "Management--Discovery Option Plan." Such options
do not confer upon holders thereof any voting or any other rights of a
stockholder of the Company. The shares of Common Stock issuable upon exercise of
the options and warrants in accordance with the terms thereof, will be fully
paid and nonassessable.
    

Any issuance of stock pursuant to the Stock Option Plan may dilute the value of
the shares of Common Stock.

PLACEMENT AGENT WARRANTS

The following summaries are qualified in their entirety by the text of the
warrants, copies of which have been filed as exhibits to the Registration
Statement.

In connection with services rendered by Paramount, as placement agent in the
Unit Offering, and pursuant to a placement agency agreement entered into by the
Company and Paramount, the Company issued to Paramount and/or its designees
warrants to acquire approximately 220,026 newly issued shares of Series A
Preferred Stock (the "Preferred Placement Warrants"). Each Preferred Placement
Warrant entitles the registered holder thereof to purchase Series A Preferred
Stock at a price of $11 per share, at any time until November 8, 2006. In
connection therewith, the Company also issued to Paramount and/or its designees
warrants to acquire approximately 220,026 newly issued shares of Common Stock
(the "Common Placement Warrants," and collectively with the Preferred Placement
Warrants, the "Placement Agent Warrants"). Each Common Placement Warrant
entitles the registered holder thereof to purchase Common Stock at a price of
$0.25 per share, at any time until November 8, 2006.

   
The Placement Agent Warrants may be exercised in whole or in part 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. The Common Stock issuable upon
conversion of the Series A Preferred Stock issuable upon exercise of the
Preferred Placement Warrants, and such Series A Preferred Stock, are subject to
certain lock-up restrictions. See "Series A Preferred Stock--Lock-up and
Blackout Periods."
    

The Placement Agent Warrants contain provisions to protect the holders thereof
against dilution by adjusting the price at which the Placement Agent Warrants
are exercisable and the number of shares issuable upon exercise thereof upon the
occurrence of certain events, including the payment of stock dividends and
distributions, stock splits, recapitalization, reclassifications and
reorganizations affecting the Company's securities and issuances of shares at
below the then market price.

The Company is not required to issue fractional shares of common Stock upon
exercise of any such warrants. In lieu thereof, an amount of cash equal to the
same fraction of the then current market value of a share of Common Stock will
be paid. No adjustment as to dividends will be made upon any exercise of any
such warrants. The holder of any such warrant will not have any rights as a
holder of Common Stock unless and until the applicable warrant is exercised for
the Common Stock issuable upon such exercise.

Each Selling Securityholder may, but is not required to, sell all of the shares
of Common Stock shown in the column entitled "Amount of Shares to be Offered"
subject, in certain instances, to lock-up provisions. See "Description of
Securities--Series A Preferred Stock--Lock-Up and Blackout Periods." The Selling
Securityholders and any broker-dealers that act in connection with the sale of
the Common Stock as principals may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act and any commission received by
them and any profit on the resale of such securities as principals might be
deemed to be underwriting discounts and commissions under the Act. The Selling
Securityholders may agree to indemnify any agent, dealer or broker-dealer that
participates in transactions involving sales of such securities certain
liabilities, including liabilities arising under the Securities Act. The Company
will not receive any proceeds from the sales of the Common Stock by the Selling
Securityholders, although the Company may receive proceeds from the exercise of
the Placement Agent Warrants. Sales by the Selling Securityholders, or even the
potential for such sales, would likely have an adverse effect on the market
price of the Common Stock.

At the time a particular offer for Common Stock is made, except as herein
contemplated, by or on behalf of the Selling Securityholder, to the extent
required, a Prospectus will be distributed by the Selling Securityholder which
will set forth the number of shares of Common Stock being offered and the terms
of the Offering, including the name or names of any underwriters, dealers or
agents, if any, the purchase price paid by any underwriter for shares purchased
from the Selling Securityholder and any discounts, commissions or concessions
allowed or reallowed or paid to dealers.
   
Except as noted below, none of the Selling Securityholders named in the
preceding table has had any position, office or other material relationship with
the Company or any of its affiliates within the past three years. The Aries
Domestic Fund, L.P. and The Aries Fund, a Cayman Island Trust are private
investment funds managed by ^ Lindsay A. Rosenwald, M.D., the Chief Executive
Officer of RAQ, LLC, the controlling stockholder of the Company and the Chairman
of the Board of Directors, Chief Executive Officer, President and sole
stockholder of Paramount. PARAMOUNT ACTED AS PLACEMENT AGENT FOR THE COMPANY'S
PRIVATE EQUITY PLACEMENT CONDUCTED DURING JUNE THROUGH NOVEMBER OF 1996. SEVERAL
EMPLOYEES OF THE COMPANY ARE OR PREVIOUSLY WERE AFFILIATED WITH PARAMOUNT. See
"Certain Transactions." Harris Kanzer is the father of Steve H. Kanzer, C.P.A.,
ESQ., the Chairman of the Board of Directors and a stockholder of the Company.
Marc Florin and Martin Kratchman are registered representatives of Paramount.
    
                        SHARES ELIGIBLE FOR FUTURE SALES
   
Upon completion of the Offering, the Company will have 17,298,909 shares of
Common Stock outstanding or issuable upon the conversion of the Series A
Preferred Stock and the exercise of all outstanding options and warrants as of
January 2, 1997. Of these shares, the 12,101,409 shares registered in the
Offering will be freely tradeable without restriction or further registration
under the Securities Act, except that (i) any shares purchased by "affiliates"
of the Company, as the term is defined under the Securities Act ("Affiliates"),
may generally only be sold in compliance with the limitations of Rule 144
described below and (ii) such registered shares that are subject to certain
lock-up provisions discussed below. In addition, the Company believes that there
are no shares of Common Stock that are eligible for sale without restriction or
further registration under the Securities Act, subject to certain requirements.
See "Risk Factors--Potential Adverse Effect of Shares Eligible For Future
Sales."
    
SALES OF RESTRICTED SHARES

The Company believes that 4,512,000 outstanding shares of Common Stock are
"restricted securities" and under certain circumstances may, in the future, be
sold in compliance with Rule 144. Assuming the availability of Rule 144, the
Company believes that 1,132,500 "restricted" shares of Common Stock are
currently eligible for sale and that an additional 3,379,500 "restricted" shares
of Common Stock will be eligible for sale in 1998 and 1999, in each case so long
as there is adequate current public information with respect to the Company as
contemplated by Rule 144, as well as, certain volume limitations and manner of
sale requirements imposed by Rule 144.

In general, under Rule 144, subject to the satisfaction of certain other
conditions, a person, including an affiliate of the Company, who beneficially
owned restricted shares of Common Stock for at least two years is entitled to
sell, within any three-month period, a number of shares that does not exceed the
greater of one percent of the total number of outstanding shares of the same
class, or if the Common Stock is quoted on the Nasdaq Small-Cap Market or a
national securities

exchange, the average weekly trading volume during the four calendar weeks
immediately preceding the sale. A person who presently is not and who has not
been an affiliate of the Company for at least three months immediately preceding
the sale and who has beneficially owned the shares of Common Stock for at least
three years is entitled to sell such shares under Rule 144(K) without regard to
the volume limitations described above. THE COMMISSION HAS RECENTLY ADOPTED
REVISIONS TO RULE 144 AND RULE 144(K), THE EFFECT OF WHICH WILL BE TO SHORTEN
THE HOLDING PERIOD UNDER RULE 144 FROM TWO YEARS TO ONE YEAR AND TO SHORTEN THE
HOLDING PERIOD UNDER RULE 144(K) FROM THREE YEARS TO TWO YEARS.

Prior to the Offering, there has been no public market for the Common Stock and
no predictions can be made of the effect, if any, that the sale or availability
for sale of "RESTRICTED" SHARES OR locked-up shares will have on the market
price of the Common Stock. Nevertheless, sales of substantial amounts of such
shares in the public market, or the perception that such sales could occur,
could adversely affect the market price of the Common Stock and could impair the
Company's future ability to raise capital through an offering of its equity
securities.

"Description of Securities--Stock Options" and "--Placement Agent Warrants."

                              PLAN OF DISTRIBUTION

The Selling Securityholders may, but are not required to, sell, directly or
through brokers, the shares of Common Stock in negotiated transactions or in one
or more transactions in the market at the price prevailing at the time of sale.
(Certain of the Common Stock is subject to a lock-up agreement. See "Description
of Securities--Lock-Up Agreements".) In connection with such sales, the Selling
Securityholders and any participating broker may be deemed to be "underwriters"
of the shares of Common Stock within the meaning of the Securities Act, although
the offering of these securities will not be underwritten by a broker-dealer
firm. Sales in the market may be made to broker-dealers making a market in the
Common Stock or other broker-dealers, and such broker-dealer, upon their resale
of such securities, may be deemed to be "Selling Securityholders" in this
offering. The Company will not receive any of the proceeds from the sale of the
Common Stock by the Selling Securityholders. Pursuant to the terms under which
the Common Stock, the Series A Preferred Stock and Placement Agent Warrants were
issued and sold, the Company has agreed to indemnify the Selling Securityholders
against such liabilities they may incur as a result of any untrue statement of a
material fact in the Registration Statement of which this Prospectus forms a
part, or any omission herein or therein to state a material fact necessary in
order to make the statements made, in the light of the circumstances under which
they were made, not misleading. Such indemnification includes liabilities that
the Selling Securityholders may incur under the Securities Act.

The Company will bear all costs and expenses of the registration under the
Securities Act and certain state securities laws of the Common Stock and any
discounts or commissions payable with respect to sales of such securities.

From time to time, this Prospectus will be supplemented and amended as required
by the Securities Act. During any time when a supplement or amendment is so
required, after notice from the Company, the Selling Securityholders are
required to cease sales until the Prospectus has been supplemented or amended.

The Selling Securityholders have advised the Company that they may sell,
directly or through brokers, all or a portion of the securities offered hereby
in negotiated transactions or in one or more transactions in the market at the
price prevailing at the time of sale. In connection with such sales, the Selling
Securityholders and any participating broker may be deemed to be "underwriters"
of the Common Stock within the meaning of the Securities Act of 1933. It is
anticipated that usual and customary brokerage fees will be paid by the Selling
Securityholders in all open market transactions. The Company will pay all other
expenses of this Offering. The Company will advise the Selling Securityholders 
that no NASD member participating in the offering of the shares of Common 
Stock being offered hereby by the Selling Securityholders may receive 
compensation in excess of 8% of the proceeds of the sale of such shares. In 
addition, the terms and arrangements of any underwritten offering must be 
filed with the NASD for its review pursuant to Section 2710 of the NASD's 
Corporate Financing Rules.

The Company will inform the Selling Securityholders that the anti-manipulation
provisions of  Regulation M  under the  Securities Exchange  Act of 1934
may apply to the sales of their shares offered hereby. The Company will advise
the Selling Securityholders of the requirement for delivery of this Prospectus
in connection with any sale of the Common Stock offered hereby.

Certain Selling Securityholders may from time to time purchase shares of Common
Stock in the open market. These Selling Securityholders have been notified 
that they should not commence any distribution of Common Stock unless they 
have terminated their purchasing and bidding for Common Stock in the open 
market as provided in applicable securities regulations, including, 
without limitation, Regulation M.

         We have audited the accompanying consolidated balance sheet of
Discovery Laboratories, Inc. and subsidiary (a development stage company) as at
December 31, 1996, and the related consolidated statements of operations,
changes in stockholders' equity and cash flows for the two years ended December
31, 1996, and the period from May 18, 1993 (inception) to December 31, 1996.
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 audits 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 statements presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements enumerated above
present fairly, in all material respects, the financial position of Discovery
Laboratories, Inc. and subsidiary at December 31, 1996, and the results of their
operations and their cash flows for the two years ended December 31, 1996, and
the period from May 18, 1993 (inception) to December 31, 1996 in conformity with
generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS


(NOTE A) - The Company and Basis of Presentation:

         Discovery Laboratories, Inc. (the "Company") was incorporated in
Delaware on May 18, 1993 as MicroBio, Inc. The Company is a development stage
company formed to license and develop pharmaceutical products to treat a variety
of human diseases. The consolidated financial statements include the accounts of
the Company and its 75% owned subsidiary Acute Therapeutics, Inc. (see Note G).
Intercompany balances and transactions have been eliminated.

         In November 1996 the Company completed a private placement of its
securities and received aggregate net proceeds of approximately $19,000,000 (see
Note F).


(NOTE B) - 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]  Computer equipment:

                  Computer equipment is recorded at cost. Depreciation is
computed using the straight-line method over the useful lives of the assets
(five years).

         [3]      License fees:

                  License fees are capitalized and are being amortized on a
straight-line basis over their respective terms of 15 to 17 years.

         [4]      Research and development:

                  Research and development costs are charged to operations as
incurred.

         [5]  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.

                          NOTES TO FINANCIAL STATEMENTS


(NOTE B) - Summary of Significant Accounting Policies:  (continued)

         [6]  Stock-based compensation:

                  During 1996, 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 stock options or to continue to follow the intrinsic
value method set forth in APB 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 stock option incentive plans. See
Note H to the financial statements for further information.

         [7]      Net loss per share:

                  Net loss per share is computed based on the weighted average
number of common shares outstanding for the periods. Common stock equivalents
are antidilutive and therefore excluded from the calculation.


(NOTE C) - Employment Agreements:

         An employment agreement with the Company's president provides for an
annual salary of $175,000 through April 1999. Employment agreements with two
executive officers provide for aggregate annual salaries of $295,000 through
December 1999, subject to certain increases.


(NOTE D) - Income Taxes:

         At December 31, 1996, the Company has available for federal income tax
purposes net operating loss carryforwards of approximately $350,000 expiring
through 2011, that may be used 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
research and development supplies and to certain general and administrative
costs which are not currently deductible for tax purposes. The Company has
provided a valuation reserve against the full amount of the deferred tax asset
arising from net operating loss benefit of approximately $130,000, the research
and

development write-off of approximately $850,000 and general and administrative
costs of approximately $250,000 since the likelihood of realization cannot be
determined. The valuation reserve increased by approximately $1,223,000 and
$7,000 for the years ended December 31, 1996 and December 31, 1995,
respectively. Pursuant to Section 382 of the Internal Revenue Code, the
utilization of this carryforward may be limited due to ownership changes which
have occurred or may occur.


(NOTE E) - License Agreements:

         [1] 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 $86,400 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.

(NOTE G) - Investment in Acute Therapeutics, Inc.:

         [1]  Formation of Acute Therapeutics, Inc.:

                  On October 28, 1996, the Company invested $7.5 million in a
newly formed subsidiary, Acute Therapeutics, Inc. ("ATI"), in exchange for
600,000 shares of Series A convertible preferred stock of ATI, representing 75%
of the outstanding voting securities of ATI following such transaction.

                  Concurrently with the Company's investment in ATI, Johnson &
Johnson, Inc. ("J & J"), J & J's wholly-owned subsidiary, Ortho Pharmaceuticals,
Inc., and ATI entered into an agreement (the "J & J License Agreement") granting
an exclusive license of KL4-Surfactant technology to 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 ATI common stock. J & J
contributed its KL4-Surfactant raw material inventory and manufacturing
equipment to ATI in exchange for 2,200 shares of nonvoting Series B preferred
stock of ATI having a $2.2 million liquidation preference and a $100 per share
cumulative dividend. The inventory and equipment were valued at $2,200,000 (the
value of the preferred shares issued to J & J) and were charged to expense as
their intended use is for research and development activities. The Scripps
Research Institute received 40,000 shares of common stock of ATI in exchange for
its consent to the J & J License Agreement.

                  The founders of ATI purchased an aggregate of 120,000 shares
of ATI common stock for $.01 per share and were granted options to purchase an
aggregate of 44,800 shares of common stock of ATI at an exercise price of $.01
per share vesting after a five-year term, subject to acceleration and 40,000
shares of common stock of ATI at an exercise price of $.32 per share vesting in
April 1997.

(NOTE G) - Investment in Acute Therapeutics, Inc.:  (continued)

         [2]  Commitments:

                  ATI entered into a four-year employment agreement with its
President, Chief Executive Officer and Chairman of the Board of Directors
providing for a base salary of $225,000 per year plus an initial sign-on bonus
of $50,000 to be paid the first week of January 1997, plus certain incentive
bonuses.

                  ATI also entered into various two-year consulting agreements
providing for aggregate annual fees of $300,000 plus royalties on net commercial
sales of licensed products sold by ATI or its sublicensees and an 18-month
consulting agreement providing for monthly fees of $7,500.

                  ATI leases its office and laboratory space pursuant to an
operating lease requiring aggregate annual payments of approximately $67,000
through November 2001.

         [3]  ATI stock option plan:

                  ATI adopted the 1996 Stock Option/Stock Issuance Plan (the
"ATI Plan") consisting of a Discretionary Option Grant program for employees and
an Automatic Option Grant Program under which option grants will automatically
be made at periodic intervals to eligible nonemployee directors to purchase
shares of common stock, in either case at an exercise price equal to at least
85% of the fair market value of the common stock on the grant date. Under the
Discretionary Option Grant program, options will be granted to employees either
as incentive stock options or nonstatutory options and will vest over a
specified period of time (generally three to five years) as determined by the
ATI Board of Directors. ATI has reserved 234,800 shares of common stock for
issuance under these plans. Options for 173,800 shares of common stock have been
granted through January 1997.


(NOTE H) - Stock Options:

         In November 1996, the Company adopted its 1996 Stock Option/Stock
Issuance Plan which includes three equity programs (the "Discovery 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. The maximum number of shares of common stock which maybe issued over
the term of plan shall not exceed 1,250,000.

                          NOTES TO FINANCIAL STATEMENTS


(NOTE H) - Stock Options:  (continued)

         In July and August, 1996, options to purchase 100,000 shares of the
Company's common stock were granted (all of which were immediately exercisable),
with a weighted average exercise price of $.125 per share. Options to purchase
25,000 shares at $.10 per share were exercised in July 1996 and options to
purchase 25,000 shares at $.20 per share were exercised in November 1996.

         The Company applies APB 25 in accounting for the Discovery Plan and the
ATI Plan 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, (1) the vesting
period of the stock options and the (2) 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 in 1996 would have been approximately $3,248,000 or $.77
per share. The fair value of the options granted are estimated as $.06 and $7
per share for the Discovery Plan and the ATI Plan, respectively, on the date of
grant using the Black-Scholes option-pricing model with the following weighted
average assumptions: dividend yield 0%, volatility of 0%, risk-free interest
rate of 6.7% for 1996, and expected life of ten years.

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

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law ("Section 145") authorizes a
court to award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article Tenth of Discovery's Certificate of
Incorporation provides that the Corporation shall indemnify and advance expenses
to its directors ands officers to the fullest extent permitted by Section 145 of
the Delaware General Corporation Law. Article Ninth of Discovery's Certificate
of Incorporation provides that the liability of its directors is eliminated to
the fullest extent permitted by Section 102(b)(7) of the Delaware General
Corporation Law. These provisions in the Certificate of Incorporation do not
eliminate the directors' fiduciary duty, and in appropriate circumstances
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under Delaware law. In addition, each director will continue to
be subject to liability for breach of the director's duty of loyalty to the
Company for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are unlawful under Delaware law. The
provisions also do not affect a director's responsibilities under any other law,
such as the federal securities laws or state or federal environmental laws.
Reference is made to Section 5.6 of the Subscription Agreements relating to the
Unit Offering (Exhibit 4.3), Section    of the Common Placement Warrant (Exhibit
4.7) and Section    of the Preferred Placement Warrant (Exhibit 4.8)
indemnifying against certain liabilities certain of the Company's stockholders
or Paramount Capital, Inc., a company wholly owned by Lindsay A. Rosenwald,
M.D., who also is the Chief Executive Officer of and a shareholder in RAQ, LLC,
a substantial shareholder of the Company.

underwriting discounts and commissions, payable by the Company in connection
with the sale of securities being registered. The following table includes costs

ITEM 26.  RECENT SALES OF UNREGISTERED SECURITIES

        IN THE LAST THREE YEARS, THE COMPANY HAS ISSUED AND SOLD THE FOLLOWING:

             1. ON AUGUST 29, OCTOBER 18 AND NOVEMBER 8, 1996 (THE "CLOSING
             DATES"), THE COMPANY CONSUMMATED A PRIVATE PLACEMENT OF AN
             AGGREGATE OF APPROXIMATELY $22,000,000 IN GROSS PROCEEDS FOR
             ("UNITS") OF SERIES A PREFERRED STOCK AND COMMON STOCK (THE "SERIES
             A OFFERING"). THE ISSUANCE OF THE ABOVE REFERENCED SECURITIES WAS
             DEEMED TO BE EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT IN
             RELIANCE ON SECTION 4(2) THEREOF AND RULE 506 OF REGULATION D
             PROMULGATED THEREUNDER.

                  THE OFFER AND SALE OF UNITS WERE CONDUCTED THROUGH THE
             COMPANY'S PLACEMENT AGENT (AS DEFINED BELOW). IN OFFERING THE
             UNITS, THE PLACEMENT AGENT CONFINED ITS ACTIONS TO ACTIVITIES
             SANCTIONED BY REGULATION D AND DID NOT ENGAGE IN ANY FORM OF
             GENERAL ADVERTISING OR GENERAL SOLICITATION IN OFFERING THE UNITS.
             ALL INVESTORS OF THE UNITS REPRESENTED TO THE COMPANY THAT THEY
             WERE ACCREDITED INVESTORS AND THE COMPANY HAD NO REASON TO BELIEVE
             THAT SUCH INVESTORS WERE NOT ACCREDITED INVESTORS. THE CLOSING
             DATES WERE THE ONLY DATES THAT THE COMPANY SOLD UNITS. EACH OF THE
             PURCHASERS OF THE UNITS REPRESENTED THEIR INTENTIONS TO ACQUIRE THE
             SECURITIES FOR INVESTMENT ONLY AND NOT WITH A VIEW TO, OR FOR SALE
             IN CONNECTION WITH, ANY DISTRIBUTION THEREOF AND APPROPRIATE
             LEGENDS WERE AFFIXED TO THE SHARE CERTIFICATES ISSUED IN SUCH
             TRANSACTIONS. THE PURCHASERS IN SUCH OFFERING OF UNITS WERE ALL THE
             SELLING SECURITY HOLDERS LISTED AS SUCH IN THE REGISTRATION
             STATEMENT.

             2. IN CONNECTION WITH SERVICES RENDERED BY PARAMOUNT CAPITAL, INC.,
             AS PLACEMENT AGENT IN THE OFFERING (THE "PLACEMENT AGENT"), THE
             COMPANY ISSUED TO THE PLACEMENT AGENT OR ITS DESIGNEES WARRANTS TO
             PURCHASE AN AGGREGATE OF APPROXIMATELY 220,026 SHARES OF SERIES A
             PREFERRED STOCK AND APPROXIMATELY 220,026 SHARES OF COMMON STOCK.
             THE ISSUANCE OF THE ABOVE REFERENCED SECURITIES WAS DEEMED TO BE
             EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT IN RELIANCE ON
             SECTION 4(2) THEREOF AND RULE 506 OF REGULATION D PROMULGATED
             THEREUNDER. EACH OF SUCH RECIPIENTS HAD THE SOPHISTICATION,
             KNOWLEDGE AND EXPERIENCE IN FINANCIAL MATTERS AS TO BE CAPABLE OF
             EVALUATING THE MERITS AND RISKS OF ITS INVESTMENT IN THE COMPANY,
             AND HAD ACCESS TO INFORMATION, AND THE OPPORTUNITY PRIOR TO ITS
             INVESTMENT TO ASK QUESTIONS OF AND RECEIVE ANSWERS FROM
             REPRESENTATIVES OF THE COMPANY, IN EACH CASE CONCERNING THE
             FINANCES, OPERATIONS AND BUSINESS OF THE COMPANY. IN ADDITION, THE
             RECIPIENTS OF SECURITIES IN EACH SUCH TRANSACTION REPRESENTED THEIR
             INTENTIONS TO ACQUIRE THE SECURITIES FOR INVESTMENT ONLY AND NOT
             WITH A VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION
             THEREOF AND APPROPRIATE LEGENDS WERE AFFIXED TO THE CERTIFICATES
             ISSUED IN SUCH TRANSACTIONS.

             TO STEVE H. KANZER, THE CHAIRMAN (AND THEN THE CHIEF EXECUTIVE
             OFFICER) OF THE COMPANY FOR $0.002 PER SHARE. THE ISSUANCE OF THE

             REGISTRATION UNDER THE SECURITIES ACT IN RELIANCE ON SECTION 4(2)

ITEM 28.  UNDERTAKINGS

         The Company hereby undertakes that it will:

     (1)          File, during any period in which it offers or sells 
                  securities, a post-effective amendment to this registration 
                  statement to:

         (i)      Include any prospectus required by section 10(a)(3) of the
                  Securities Act;

         (ii)     Reflect in the prospectus any facts or events which,
                  individually or together, represent a fundamental change in
                  the information in the registration statement; and
                  notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in the volume and price
                  represent no more than a 20% change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective registration statement;

         (iii)    Include any additional or changed material information on the
                  plan of distribution.

     (2) For determining liability under the Securities Act, treat each
         post-effective amendment as a new registration statement of the
         securities offered, and the offering of the securities at that time to
         be the initial BONA FIDE offering.

     (3) File a post-effective amendment to remove from registration any of the
         securities that remain unsold at the end of the offering.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the By-Laws of the Company, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer, or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered hereunder, the Company 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 of whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     The Company hereby undertakes that it will:

     (1) For determining any liability under the Securities Act, treat the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Company pursuant to Rule 424(b)(1), or (4) or 497(h)
under the Securities Act as part of this registration statement as of the time
it was declared effective.

     (2) For determining any liability under the Securities Act, treat each
post-effective amendment that contains a form of prospectus as a new
registration statement for the securities offered in the registration statement,
and that offering of such securities at that time as the initial BONA FIDE
offering of those securities.

                           CERTIFICATE OF INCORPORATION
                                       OF

                 SEVENTH:  Whenever a  compromise  or  arrangement  is  proposed
 between this  corporation and its creditors or any class of them and/or between
 this  corporation  and its  stockholders  or any  class of them,  any  court of
 equitable  jurisdiction within the State of Delaware may, on the application in
 a summary way of this corporation or of any creditor or stockholder  thereof or
 on the application of any receiver or receivers  appointed for this corporation
 under  the  provisions  of ss. 291 of  Title  8 of the  Delaware  Code  or on
 the application  of  trustees  in  dissolution  or of  any  receiver  or

 creditors, and/or of the stockholders or class of stockholders of this
 corporation, as the case may be, to be  summoned  in such  manner as the said
 court  directs.  If a majority in number  representing  three  fourths in value
 of the  creditors  or class of creditors, and/or of the stockholders or class
 of stockholders of this corporation,  as the case may be, agree to any
 compromise or arrangement and to any  reorganization  of this  corporation as

 or class of  creditors,  and/or  on all the stockholders or class of
 stockholders, of this corporation, as the case may be, and also on this
 corporation.

    
              EIGHTH: For the management of the business and for the conduct
 of the affairs of the  corporation,  and in further  definition,  limitation,
 and regulation  of the powers of the  corporation  and of its  directors and of
 its stockholders or any class thereof, as the case may be, it is further
 provided:
     

         1. The management of the business and the conduct of the affairs of the
         corporation shall be vested in its Board of Directors.  The number of
         directors which shall  constitute  the whole Board of Directors  shall
         be fixed by, or in the manner  provided in, the Bylaws.  The phrase
         "whole  Board" and the phrase "total number of directors"  shall be
         deemed to have the same meaning,  to wit, the total number of directors
         which the corporation would have if there were no vacancies. No
         election of directors need be by written ballot.

         2. After the  original  or other  Bylaws of the  corporation  have been
         adopted,  amended,  or  repealed,  as the case may be, in  accordance
         with the provisions  of ss. 109 of the General  Corporation  Law of the
         State of Delaware, and,  after the  corporation  has received any
         payment for any of its Stock, the power to adopt, amend, or repeal the
         Bylaws of the corporation may be exercised by the Board of  Directors
         of the  corporation;  provided,  however,  that any provision for the
         classification of directors of the corporation for staggered terms
         pursuant to the  provisions of subsection  (d) of ss. 141 of the
         General Corporation Law of the State of Delaware shall be set forth in
         an initial Bylaw or in a Bylaw adopted by the stockholders entitled to
         vote of the

                                       -2-

 corporation unless provisions for such classification shall be set forth in
 this certificate of incorporation.

         3. Whenever the corporation  shall be authorized to issue only one
         class of stock,  each outstanding share shall entitle the holder
         thereof to notice of, and the right to vote at, any meeting of
         stockholders.  Whenever the incorporation  shall be  authorized  to
         issue  more than one class of stock,  no outstanding  share of any
         class of stock which is denied  voting  power under the provisions of
         the certificate of incorporation shall entitle the holder thereof to
         the right to vote at any meeting of stockholders except as the
         provisions of paragraph (2) of subsection (b) of ss. 242 of the General
         Corporation Law of the State of Delaware shall otherwise require;
         provided, that no share of any such class which is otherwise  denied
         voting power shall entitle the holder thereof to vote upon the increase
         or decrease in the number of authorized shares of said class.

                 NINTH:   The  personal   liability  of  the   directors  of the
 corporation  is  hereby  eliminated  to the  fullest  extent  permitted  by the
 provisions  of  paragraph  (7) of  subsection  (b) of  ss.  102 of the  General
 Corporation  Law of the  State of  Delaware,  as the same  may be  amended  and
 supplemented.

                 TENTH: The corporation  shall, to the fullest extent permitted
 by the  provisions of ss. 145 of the General  Corporation  Law  of  the  State
 of Delaware,  as the same may be amended and  supplemented,  indemnify any and
 all persons  whom it shall have power to  indemnify  under said  section  from
 and against any and all of the expenses,  liabilities, or other matters
 referred to in or covered by said  section,  and the  indemnification  provided
 for herein shall not be deemed  exclusive of any other  rights to which those
 indemnified may  be  entitled  under  any  Bylaw,   agreement,   vote  of
 stockholders  or disinterested  directors  or  otherwise,  both  as to  action
 in his  official capacity and as to action in another  capacity  while holding
 such office,  and shall  continue  as to a  person  who has  ceased  to be a
 director,  officer, employee, or agent and shall inure to the benefit of the
 heirs, executors,  and administrators of such a person.

                 ELEVENTH:  From  time to time  any of the  provisions  of this
 certificate of incorporation may be amended,  altered,  or repealed,  and other
 provisions authorized by the laws of the State of Delaware at the time in force
 may be added or  inserted  in the  manner and at the time  prescribed  by said
 laws,  and all  rights  at any  time  conferred  upon the  stockholders  of the
 corporation by this  certificate of  incorporation  are granted  subject to the
 provisions of this Article ELEVENTH.

                General Corporation Law of the State of Delaware


                  DISCOVERY LABORATORIES, INC., a corporation organized and
existing under the laws of the State of Delaware (the "Corporation"), does
hereby certify that, pursuant to the authority conferred on the Board of
Directors of the Corporation by the Certificate of Incorporation, as amended, of
the Corporation and in accordance with Section 151 of the General Corporation
Law of the State of Delaware, the Board of Directors of the Corporation adopted
the following resolution establishing a series of 3,000,000 shares of Preferred
Stock of the Corporation designated as "Series A Convertible Preferred Stock":

                  RESOLVED, that pursuant to the authority conferred on the
         Board of Directors of this Corporation by the Certificate of
         Incorporation, as amended, a series of Preferred Stock, par value $.001
         per share, of the Corporation is hereby established and created, and
         that the designation and number of shares thereof and the voting and
         other powers, preferences and relative, participating, optional or
         other rights of the shares of such series and the qualifications,
         limitations and restrictions thereof are as follows:

                      Series A Convertible Preferred Stock


1. Designation and Amount. There shall be a series of Preferred Stock designated
as "Series A Convertible Preferred Stock" and the number of shares constituting
such series shall be 3,000,000. Such series is referred to herein as the "Series
A Convertible Preferred Stock". Such number of shares may be increased or
decreased by resolution of the Board of Directors of the Corporation; provided,
however, that no decrease shall reduce the number of shares of Series A
Convertible Preferred Stock to less than the number of shares then issued and
outstanding.

                  2. Dividends. Subject to the prior and superior rights of the
holders of any shares of any series or class of capital stock ranking prior and
superior to the shares of Series A Convertible Preferred Stock with respect to
dividends and distributions, the holders of shares of Series A Convertible
Preferred Stock, shall

                                       -1-

<PAGE>



be entitled to receive dividends and distributions, when, as and if declared by
the Board of Directors out of funds legally available for such purpose. If the
Corporation declares a dividend or distribution on the common stock, par value
$.001 per share (the "Common Stock"), of the Corporation, the holders of shares
of Series A Convertible Preferred Stock shall be entitled to receive for each
share of Series A Convertible Preferred Stock a dividend or distribution in the
amount of the dividend or distribution that would be received by a holder of the
Common Stock into which such share of Series A Convertible Preferred Stock is
convertible on the record date for such dividend or distribution. If the
Corporation declares a dividend or distribution on any other class or series of
preferred stock, the holders of shares of Series A Convertible Preferred Stock
shall be entitled to receive a dividend or distribution in an amount per share
in proportion to the dividend or distribution declared on a share of such other
class or series based upon the liquidation preference of a share of the Series A
Convertible Preferred Stock relative to that of a share of such other class or
series, unless the holders of at least 66.67% of the outstanding shares of
Series A Convertible Preferred Stock consent otherwise. In any such case, the
Corporation shall declare a dividend or distribution on the Series A Convertible
Preferred Stock at the same time that it declares a dividend or distribution on
the Common Stock or such other class or series of preferred stock and shall
establish the same record date for the dividend or distribution on the Series A
Convertible Preferred Stock as is established for such dividend or distribution
on the Common Stock or such other class or series of preferred stock. Each such
dividend or distribution will be payable to holders of record of the Series A
Convertible Preferred Stock as they appeared on the records of the Corporation
at the close of business on the record date declared for such dividend or
distribution, as shall be fixed by the Board of Directors. Any dividend or
distribution payable to the holders of the Series A Preferred Stock pursuant to
this Section 2 shall be paid to such holders at the same time as the dividend or
distribution on the Common Stock by which it is measured or paid. If the
corporation declares or pays a dividend or distribution on the Series A
Convertible Preferred Stock as a result of the declaration or payment of a
dividend or distribution on the Common Stock or any other class or series of
preferred stock as described above, the holders of the Series A Convertible
Preferred Stock shall not be entitled to any additional dividend or distribution
solely because such first dividend or distribution also required the declaration
or payment of a dividend or distribution on any other class or series of
preferred stock. Any reference to "dividend" or "distribution" contained in this
Section 2 shall not be deemed to include any dividend or distribution made in
connection with or in lieu of any Liquidation Event (as defined below).

                  3. Liquidation Preference. In the event of a (i) liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
(ii) a sale or other disposition of all or substantially all of the assets of
the Corporation or (iii) any consolidation, merger, combination, reorganization
or other transaction in which the Corporation is not the surviving entity or the
shares of Common Stock constituting in excess of 50% of the voting power of the
Corporation are exchanged for or changed into other stock or securities, cash
and/or any other property (a "Merger Transaction") (subparagraphs (i), (ii) and
(iii) being collectively referred to as a "Liquidation Event"), after payment or
provision for payment of debts and other liabilities of the Corporation, the
holders of the Series A Convertible Preferred Stock then outstanding shall be
entitled to be paid out of the assets of the Corporation available for
distribution to its shareholders, whether such assets are capital, surplus, or
earnings, before any payment or declaration and setting apart for payment of any
amount shall be made in respect of the stock junior to the Series A Convertible
Preferred Stock, an amount equal to $13.50 per share plus an amount equal to all
declared and unpaid dividends thereon; provided, however, in the case of Section
3(iii) above, such $13.50 per share may be paid in cash and/or securities
(valued at the closing price (as defined in Section 5) of such security) of the
entity surviving such Merger Transaction. If upon any Liquidation Event, whether
voluntary or involuntary, the assets to be distributed to the holders of the
Series A Convertible Preferred Stock shall be insufficient to permit the payment
to such shareholders of the full preferential amounts aforesaid, then all of the
assets of the Corporation to be distributed shall be so distributed ratably to
the holders of the Series A Convertible Preferred Stock on the basis of the
number of shares of Series A Convertible Preferred Stock held. A consolidation
or merger of the Corporation with or into another corporation, other than in a
transaction described in Section 3(iii) above, shall not be considered a
liquidation, dissolution or winding up of the

                                       -2-

<PAGE>



Corporation or a sale or other disposition of all or substantially all of the
assets of the Corporation and accordingly the Corporation shall make appropriate
provision to ensure that the terms of this Certificate of Designations survive
any such transaction. All shares of Series A Convertible Preferred Stock shall
rank as to payment upon the occurrence of any Liquidation Event senior to the
Common Stock as provided herein and, unless the terms of such series shall
provide otherwise, senior to all other series of the Corporation's preferred
stock.

                  4.       Conversion.

                  (a) Right of Conversion. The shares of Series A Convertible
Preferred Stock shall be convertible, in whole or in part, at the option of the
holder thereof and upon notice to the Corporation as set forth in paragraph (b)
below, into fully paid and nonassessable shares of Common Stock and such other
securities and property as hereinafter provided. The shares of Series A
Convertible Preferred Stock shall be convertible initially at the rate of 4.0
shares of Common Stock for each full share of Series A Convertible Preferred
Stock and shall be subject to adjustment as provided herein. The initial
conversion price per share of Common Stock is $2.50 and shall be subject to
adjustment as provided herein. For purposes of this resolution, the "conversion
rate" applicable to a share of Series A Convertible Preferred Stock shall be the
number of shares of Common Stock and number or amount of any other securities
and property as hereinafter provided into which a share of Series A Convertible
Preferred Stock is then convertible and shall be determined by dividing the then
existing conversion price into $10.00.

                  The conversion price (subject to adjustments pursuant to the
provisions of paragraph (c) below) in effect immediately prior to the date (the
"Reset Date") that is 12 months after the effective date of the shelf
registration statement covering the shares of Common Stock issuable upon
conversion of the Series A Convertible Preferred Stock shall be adjusted and
reset effective as of the Reset Date if the average closing bid price of the
Common Stock for the 30 consecutive trading days immediately preceding the Reset
Date (the "12-Month Trading Price") is less than 135% of the then applicable
conversion price (a "Reset Event"). Upon the occurrence of a Reset Event, the
conversion price shall be reduced to be equal to the greater of (A) the 12-Month
Trading Price divided by 1.35 and (B) 50% of the then applicable conversion
price. If there is any change in the conversion price as a result of the
preceding sentence, then the conversion rate shall be changed accordingly, and
shall be determined by dividing the new conversion price into $10.00. The
Corporation shall prepare a certificate signed by the principal financial
officer of the Corporation setting forth the conversion rate as of the Reset
Date, showing in reasonable detail the facts upon which such conversion rate is
based, and such certificate shall be forthwith filed with the transfer agent of
the Series A Convertible Preferred Stock. Notwithstanding the provisions of
subparagraph (vi) of paragraph (c) below, a notice stating that the conversion
rate has been adjusted pursuant to this paragraph, or that no adjustment is
necessary, and setting forth the conversion rate in effect as of the Reset Date
shall be mailed as promptly as practicable after the Reset Date by the
Corporation to all record holders of the Series A Convertible Preferred Stock at
their last addresses as they shall appear in the stock transfer books of the
Corporation.

                  The "closing bid price" for each trading day shall be the
reported closing bid price on the NASDAQ Small-Cap Market or the NASDAQ National
Market System (collectively referred to as, "NASDAQ") or, if the Common Stock is
not quoted on NASDAQ, on the principal national securities exchange on which the
Common Stock is listed or admitted to trading (based on the aggregate dollar
value of all securities listed or admitted to trading) or, if not listed or
admitted to trading on any national securities exchange or quoted on NASDAQ, the
closing bid price in the over-the-counter market as furnished by any NASD member
firm selected from time to time by the Corporation for that purpose, or, if such
prices are not available, the fair market value set by, or in a manner
established by, the Board of Directors of the Corporation in good faith.
"Trading day" shall mean a day on which the national securities exchange or
NASDAQ used to determine the closing bid price is open

                                       -4-

<PAGE>



for the transaction of business or the reporting of trades or, if the closing
bid price is not so determined, a day on which NASDAQ is open for the
transaction of business.

                  (b) Conversion Procedures. Any holder of shares of Series A
Convertible Preferred Stock desiring to convert such shares into Common Stock
shall surrender the certificate or certificates evidencing such shares of Series
A Convertible Preferred Stock at the office of the transfer agent for the Series
A Convertible Preferred Stock, which certificate or certificates, if the
Corporation shall so require, shall be duly endorsed to the Corporation or in
blank, or accompanied by proper instruments of transfer to the Corporation or in
blank, accompanied by irrevocable written notice to the Corporation that the
holder elects so to convert such shares of Series A Convertible Preferred Stock
and specifying the name or names (with address) in which a certificate or
certificates evidencing shares of Common Stock are to be issued. The Corporation
need not deem a notice of conversion to be received unless the holder complies
with all the provisions hereof. The Corporation will instruct the transfer agent
(which may be the Corporation) to make a notation of the date that a notice of
conversion is received, which date shall be deemed to be the date of receipt for
purposes hereof.

                  The Corporation shall, as soon as practicable after such
deposit of certificates evidencing shares of Series A Convertible Preferred
Stock accompanied by the written notice and compliance with any other conditions
herein contained, deliver at such office of such transfer agent to the person
for whose account such shares of Series A Convertible Preferred Stock were so
surrendered, or to the nominee or nominees of such person, certificates
evidencing the number of full shares of Common Stock to which such person shall
be entitled as aforesaid, together with a cash adjustment of any fraction of a
share as hereinafter provided. Subject to the following provisions of this
paragraph, such conversion shall be deemed to have been made as of the date of
such surrender of the shares of Series A Convertible Preferred Stock to be
converted, and the person or persons entitled to receive the Common Stock
deliverable upon conversion of such Series A Convertible Preferred Stock shall
be treated for all purposes as the record holder or holders of such Common Stock
on such date; provided, however, that the Corporation shall not be required to
convert any shares of Series A Convertible Preferred Stock while the stock
transfer books of the Corporation are closed for any purpose, but the surrender
of Series A Convertible Preferred Stock for conversion during any period while
such books are so closed shall become effective for conversion immediately upon
the reopening of such books as if the surrender had been made on the date of
such reopening, and the conversion shall be at the conversion rate in effect on
such date. No adjustments in respect of any dividends on shares surrendered for
conversion or any dividend on the Common Stock issued upon conversion shall be
made upon the conversion of any shares of Series A Convertible Preferred Stock.

                  All notices of conversion shall be irrevocable; provided,
however, that if the Corporation has sent notice of an event pursuant to
Sections 4(f) and (g) hereof, a holder of Series A Convertible Preferred Stock
may, at its election, provide in its notice of conversion that the conversion of
its shares of Series A Convertible Preferred Stock shall be contingent upon the
occurrence of the record date or effectiveness of such event (as specified by
such holder), provided that such notice of conversion is received by the
Corporation prior to such record date or effective date, as the case may be.

                  (c) Certain Adjustments of Conversion Rate. In addition to
adjustment pursuant to paragraph (a) above, the conversion rate (and the
corresponding conversion price) shall be subject to adjustment from time to time
as follows:

                  (i) In case the Corporation shall (A) pay a dividend in Common
         Stock or make a distribution in Common Stock, (B) subdivide its
         outstanding Common Stock, (C) combine its outstanding Common Stock into
         a smaller number of shares of Common Stock or (D) issue by
         reclassification of its Common Stock other securities of the
         Corporation, then in each such case the conversion rate in effect
         immediately prior thereto shall be adjusted so that the holder of any
         shares of



                                      -4-

<PAGE>


         Series A Convertible Preferred Stock thereafter surrendered for
         conversion shall be entitled to receive the kind and number of shares
         of Common Stock or other securities of the Corporation which such
         holder would have owned or would have been entitled to receive
         immediately after the happening of any of the events described above
         had such shares of Series A Convertible Preferred Stock been converted
         immediately prior to the happening of such event or any record date
         with respect thereto. Any adjustment made pursuant to this subparagraph
         (i) shall become effective immediately after the effective date of such
         event retroactive to the record date, if any, for such event.

                  (ii) In case the Corporation shall issue rights, options,
         warrants or convertible securities to all or substantially all holders
         of its Common Stock, without any charge to such holders, entitling them
         to subscribe for or purchase Common Stock at a price per share which is
         lower at the record date mentioned below than both (A) the then
         effective conversion price and (B) the closing bid price (as defined in
         Section 4) for the trading day immediately prior to such record date
         (the "Current Market Price"), then the conversion rate shall be
         determined by multiplying the conversion rate theretofore in effect by
         a fraction, of which the numerator shall be the number of shares of
         Common Stock outstanding immediately prior to the issuance of such
         rights, options, warrants or convertible securities plus the number of
         additional shares of Common Stock offered for subscription or purchase,
         and of which the denominator shall be the number of shares of Common
         Stock outstanding immediately prior to the issuance of such rights,
         options, warrants or convertible securities plus the number of shares
         which the aggregate offering price of the total number of shares
         offered would purchase at such Current Market Price. Such adjustment
         shall be made whenever such rights, options, warrants or convertible
         securities are issued, and shall become effective immediately and
         retroactive to the record date for the determination of stockholders
         entitled to receive such rights, options, warrants or convertible
         securities. Notwithstanding any of the foregoing, no adjustment shall
         be made pursuant to the provisions of this subsection (ii), if such
         adjustment would result in a decrease of the conversion rate.

                  (iii) In case the Corporation shall distribute to all or
         substantially all holders of its Common Stock evidences of its
         indebtedness or assets (excluding cash dividends or distributions out
         of earnings) or rights, options, warrants or convertible securities
         containing the right to subscribe for or purchase Common Stock
         (excluding those referred to in subparagraph (ii) above), then in each
         case the conversion rate shall be determined by multiplying the
         conversion rate theretofore in effect by a fraction, of which the
         numerator shall be the then fair value as determined in good faith by
         the Corporation's Board of Directors on the date of such distribution,
         and of which the denominator shall be such fair value on such date
         minus the then fair value (as so determined) of the portion of the
         assets or evidences of indebtedness so distributed or of such
         subscription rights, options, warrants or convertible securities
         applicable to one share. Such adjustment shall be made whenever any
         such distribution is made and shall become effective on the date of
         distribution retroactive to the record date for the determination of
         stockholders entitled to receive such distribution.

                  (iv) Upon the expiration of any rights, options, warrants or
         conversion privileges, if such shall not have been exercised, the
         conversion rate shall, upon such expiration, be readjusted and shall
         thereafter be such as it would have been had it been originally
         adjusted (or had the original adjustment not been required, as the case
         may be) on the basis of (A) the fact that Common Stock, if any,
         actually issued or sold upon the exercise of such rights, options,
         warrants or conversion privileges, and (B) the fact that such shares of
         Common Stock, if any, were issued or sold for the consideration
         actually received by the Corporation upon such exercise plus the
         consideration, if any, actually received by the Corporation for the
         issuance, sale or grant of all such rights, options, warrants or
         conversion privileges whether or not exercised.

                  (v) No adjustment in the conversion rate shall be required
         unless such adjustment would require an increase or decrease of at
         least 1% in such rate; provided, however, that the Corporation may make
         any such adjustment at its election; and provided, further, that any
         adjustments which by reason of this subparagraph (v) are not required
         to be made shall be carried forward and taken into account in any
         subsequent adjustment. All calculations under this Section 4 shall be
         made to the nearest cent or to the nearest one-hundredth of a share, as
         the case may be.

                  (vi) Whenever the conversion rate is adjusted as provided in
         any provision of this Section 4:

                           (A) the Corporation shall compute (or may retain a
                  firm of independent public accountants of recognized national
                  standing (which may be any such firm regularly employed by the
                  Corporation) to compute) the adjusted conversion rate in
                  accordance with this Section 4 and shall prepare a certificate
                  signed by the principal financial officer of the Corporation
                  (or cause any such independent public accountants to execute a
                  certificate) setting forth the adjusted conversion rate and
                  showing in reasonable detail the facts upon which such
                  adjustment is based, and such certificate shall forthwith be
                  filed with the transfer agent of the Series A Convertible
                  Preferred Stock; and

                           (B) a notice stating that the conversion rate has
                  been adjusted and setting forth the adjusted conversion rate
                  shall forthwith be required, and as soon as practicable after
                  it is required, such notice shall be mailed by the Corporation
                  to all record holders of Series A Convertible Preferred Stock
                  at their last addresses as they shall appear in the stock
                  transfer books of the Corporation.

                  (vii) In the event that at any time, as a result of any
         adjustment made pursuant to this Section 4, the holder of any shares of
         Series A Convertible Preferred Stock thereafter surrendered for
         conversion shall become entitled to receive any shares of the
         Corporation other than shares of Common Stock or to receive any other
         securities, the number of such other shares or securities so receivable
         upon conversion of any share of Series A Convertible Preferred Stock
         shall be subject to adjustment from time to time in a manner and on
         terms as nearly equivalent as practicable to the provisions contained
         in this Section 4 with respect to the Common Stock.


                  (d) No Fractional Shares. No fractional shares or scrip
representing fractional shares of Common Stock shall be issued upon conversion
of Series A Convertible Preferred Stock. If more than one certificate evidencing
shares of Series A Convertible Preferred Stock shall be surrendered for
conversion at one time by the same holder, the number of full shares issuable
upon conversion thereof shall be computed on the basis of the aggregate number
of shares of Series A Convertible Preferred Stock so surrendered. Instead of any
fractional share of Common Stock which would otherwise be issuable upon
conversion of any shares of Series A Convertible Preferred Stock, the
Corporation shall pay a cash adjustment in respect of such fractional interest
in an amount equal to the same fraction of the market price per share of Common
Stock (which shall be the closing price as defined in Section 5) at the close of
business on the day of conversion.

                  (e) Reservation of Shares; Transfer Taxes; Etc. The
Corporation shall at all times reserve and keep available, out of its authorized
and unissued stock, solely for the purpose of effecting the conversion of the
Series A Convertible Preferred Stock, such number of shares of its Common Stock
free of preemptive rights as shall from time to time be sufficient to effect the
conversion of all shares of Series A Convertible Preferred Stock from time to
time outstanding. The Corporation shall use its best efforts from time to time,
in accordance with the laws of the State of Delaware, to increase the authorized
number of shares of Common Stock if at any time the number of shares of Common
Stock not outstanding shall not be sufficient to permit the




                                       -6-

<PAGE>


conversion of all the then-outstanding shares of Series A Convertible Preferred
Stock.

                  The Corporation shall pay any and all issue or other taxes
that may be payable in respect of any issue or delivery of shares of Common
Stock on conversion of the Series A Convertible Preferred Stock. The Corporation
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issue or delivery of Common Stock (or other
securities or assets) in a name other than that in which the shares of Series A
Convertible Preferred Stock so converted were registered, and no such issue or
delivery shall be made unless and until the person requesting such issue has
paid to the Corporation the amount of such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

                  Notwithstanding anything to the contrary herein, before taking
any action that would cause an adjustment reducing the conversion rate or before
any such adjustment is made as a result of a Reset Event, in either event, such
that the effective conversion price (for all purposes an amount equal to $10.00
divided by the conversion rate as in effect at such time) would be below the
then par value of the Common Stock, the Corporation shall take any corporate
action which may, in the opinion of its counsel, be necessary in order that the
Corporation may validly and legally issue fully paid and nonassessable shares of
Common Stock at the conversion rate as so adjusted.

                  (f) Prior Notice of Certain Events. In case:

                  (i) the Corporation shall declare any dividend (or any other
         distribution) on its Common Stock; or

                  (ii) the Corporation shall authorize the granting to the
         holders of Common Stock of rights or warrants to subscribe for or
         purchase any shares of stock of any class or of any other rights or
         warrants; or

                  (iii) of any reclassification of Common Stock (other than a
         subdivision or combination of the outstanding Common Stock, or a change
         in par value, or from par value to no par value, or from no par value
         to par value), or of any consolidation or merger to which the
         Corporation is a party and for which approval of any stockholders of
         the Corporation shall be required, or of the sale or transfer of all or
         substantially all of the assets of the Corporation or of any compulsory
         share exchange whereby the Common Stock is converted into other
         securities, cash or other property; or

                  (iv) of the voluntary or involuntary dissolution, liquidation
         or winding up of the Corporation or other Liquidation Event;

then the Corporation shall cause to be filed with the transfer agent for the
Series A Convertible Preferred Stock, and shall cause to be mailed to the
holders of record of the Series A Convertible Preferred Stock, at their last
addresses as they shall appear upon the stock transfer books of the Corporation,
at least 20 days prior to the applicable record date hereinafter specified, a
notice stating (x) the date on which a record (if any) is to be taken for the
purpose of such dividend, distribution or granting of rights or warrants or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to
be determined and a description of the cash, securities or other property to be
received by such holders upon such dividend, distribution or granting of rights
or warrants or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, share exchange, dissolution, liquidation or winding up
is expected to become effective, the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities or other property deliverable upon such exchange,
dissolution, liquidation, winding up or other Liquidation Event and the
consideration, including


                                      -7-

<PAGE>



securities or other property, to be received by such holders upon such exchange;
provided, however, that no failure to mail such notice or any defect therein or
in the mailing thereof shall affect the validity of the corporate action
required to be specified in such notice.

                  (g) Other Changes in Conversion Rate. The Corporation from
time to time may increase the conversion rate by any amount for any period of
time if the period is at least 20 days and if the increase is irrevocable during
the period. Whenever the conversion rate is so increased, the Corporation shall
mail to holders of record of the Series A Convertible Preferred Stock a notice
of the increase at least 15 days before the date the increased conversion rate
takes effect, and such notice shall state the increased conversion rate and the
period it will be in effect.

                  The Corporation may make such increases in the conversion
rate, in addition to those required or allowed by this Section 4, as shall be
determined by it, as evidenced by a resolution of the Board of Directors, to be
advisable in order to avoid or diminish any income tax to holders of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes.

                  (h) Ambiguities/Errors. The Board of Directors of the
Corporation shall have the power to resolve any ambiguity or correct any error
in the provisions relating to the convertibility of the Series A Convertible
Preferred Stock, and its actions in so doing shall be final and conclusive.

                  5. Mandatory Conversion. At any time on or after the Reset
Date, the Corporation, at its option, may cause the Series A Convertible
Preferred Stock to be converted in whole, or in part, on a pro rata basis, into
fully paid and nonassessable shares of Common Stock and such other securities
and property as herein provided if the closing price of the Common Stock shall
have exceeded 150% of the then applicable conversion price for at least 20
trading days in any 30 consecutive trading day period. Any shares of Series A
Convertible Preferred Stock so converted shall be treated as having been
surrendered by the holder thereof for conversion pursuant to Section 4 on the
date of such mandatory conversion (unless previously converted at the option of
the holder).

                  Not more than 60 nor less than 20 days prior to the date of
any such mandatory conversion, notice by first class mail, postage prepaid,
shall be given to the holders of record of the Series A Convertible Preferred
Stock to be converted, addressed to such holders at their last addresses as
shown on the stock transfer books of the Corporation. Each such notice shall
specify the date fixed for conversion, the place or places for surrender of
shares of Series A Convertible Preferred Stock, and the then effective
conversion rate pursuant to Section 4.

                  The "closing price" for each trading day shall be the reported
last sales price regular way or, in case no such reported sale takes place on
such day, the average of the reported closing bid and asked prices regular way,
in either case on the NASDAQ or, if the Common Stock is not quoted on NASDAQ, on
the principal national securities exchange on which the Common Stock is listed
or admitted to trading (based on the aggregate dollar value of all securities
listed or admitted to trading) or, if not listed or admitted to trading on any
national securities exchange or quoted on NASDAQ, the average of the closing bid
and asked prices in the over-the-counter market as furnished by any NASD member
firm selected from time to time by the Corporation for that purpose, or, if such
prices are not available, the fair market value set by, or in a manner
established by, the Board of Directors of the Corporation in good faith.
"Trading day" shall have the meaning given in Section 4 hereof.

                  Any notice which is mailed as herein provided shall be
conclusively presumed to have been duly given by the Corporation on the date
deposited in the mail, whether or not the holder of the Series A Convertible


                                       -8-

Preferred Stock receives such notice; and failure properly to give such notice
by mail, or any defect in such notice, to the holders of the shares to be
converted shall not affect the validity of the proceedings for the conversion of
any other shares of Series A Convertible Preferred Stock. On or after the date
fixed for conversion as stated in such notice, each holder of shares called to
be converted shall surrender the certificate evidencing such shares to the
Corporation at the place designated in such notice for conversion.
Notwithstanding that the certificates evidencing any shares properly called for
conversion shall not have been surrendered, the shares shall no longer be deemed
outstanding and all rights whatsoever with respect to the shares so called for
conversion (except the right of the holders to convert such shares upon
surrender of their certificates therefor) shall terminate.

                  6.       Voting Rights.

                  (a) General. Except as otherwise provided herein, in the
Certificate of Incorporation or the By-laws, the holders of shares of Series A
Convertible Preferred Stock, the holders of shares of Common Stock and the
holders of any other class or series of shares entitled to vote with the Common
Stock shall vote together as one class on all matters submitted to a vote of
stockholders of the Corporation. In any such vote, each share of Series A
Convertible Preferred Stock shall entitle the holder thereof to cast the number
of votes equal to the number of votes which could be cast in such vote by a
holder of the Common Stock into which such share of Series A Convertible
Preferred Stock is convertible on the record date for such vote, or if no record
date has been established, on the date such vote is taken. Any shares of Series
A Convertible Preferred Stock held by the Corporation or any entity controlled
by the Corporation shall not have voting rights hereunder and shall not be
counted in determining the presence of a quorum.

                  (b) Class Voting Rights. In addition to any vote specified in
paragraph (a) of this Section 6, so long as 50% of the shares of Series A
Convertible Preferred Stock (including those shares of Series A Convertible
Preferred Stock issued or issuable upon the exercise of the warrants issued to
Paramount Capital, Inc., the placement agent in connection with the offer and
sale of the Series A Convertible Preferred Stock) shall be outstanding, the
Corporation shall not, without the affirmative vote or consent of the holders of
at least 66.67% of all outstanding Series A Convertible Preferred Stock voting
separately as a class, (i) amend, alter or repeal any provision of the
Certificate of Incorporation, as amended, or the Bylaws of the Corporation so as
adversely to affect the relative rights, preferences, qualifications,
limitations or restrictions of the Series A Convertible Preferred Stock, (ii)
declare any dividend or distribution on the Common Stock or any other class or
series of preferred stock or authorize the repurchase of any securities of the
Corporation or (iii) authorize or issue, or increase the authorized amount of,
any additional class or series of stock, or any security convertible into stock
of such class or series, (A) ranking prior to, or on a parity with, the Series A
Convertible Preferred Stock upon liquidation, dissolution or winding up of the
Corporation or a sale of all or substantially all of the assets of the
Corporation or (B) providing for the payment of any dividends or distributions.
A class vote on the part of the Series A Convertible Preferred Stock shall,
without limitation, specifically not be deemed to be required (except as
otherwise required by law or resolution of the Corporation's Board of Directors)
in connection with: (a) the authorization, issuance or increase in the
authorized amount of Common Stock or of any shares of any other class or series
of stock ranking junior to the Series A Convertible Preferred Stock in respect
of distributions upon liquidation, dissolution or winding up of the Corporation;
(b) the authorization, issuance or increase in the amount of the Series A
Convertible Preferred Stock or any bonds, mortgages, debentures or other
obligations of the Corporation (other than bonds, mortgages, debentures or other
obligations convertible into or exchangeable for or having option rights to
purchase any shares of stock of the Corporation the authorization issuance or
increase in amount of which would require the consent of the holders of the
Series B Preferred Stock); or (c) any consolidation or merger of the Corporation
with or into another corporation in which the Corporation is not the surviving
entity, a sale or transfer of all or part of the Corporation's assets for cash,
securities or other property, or a compulsory share exchange.

                  7. Outstanding Shares. For purposes of this Certificate of
Designations, all shares of Series A Convertible Preferred Stock shall be deemed
outstanding except (i) from the date, or the deemed date, of surrender of
certificates evidencing shares of Series A Convertible Preferred Stock, all
shares of Series A Convertible Preferred Stock converted into Common Stock, (ii)
from the date of registration of transfer, all shares of Series A Convertible
Preferred Stock held of record by the Corporation or any subsidiary of the
Corporation and (iii) any and all shares of Series A Convertible Preferred Stock
held in escrow prior to delivery of such stock by the Corporation to the initial
beneficial owners thereof.

                  8. Status of Acquired Shares. Shares of Series A Convertible
Preferred Stock received upon conversion pursuant to Section 4 or Section 5 or
otherwise acquired by the Corporation will be restored to the status of
authorized but unissued shares of Preferred Stock, without designation as to
class, and may thereafter be issued, but not as shares of Series A Convertible
Preferred Stock.

                  9. Preemptive Rights. The Series A Convertible Preferred Stock
is not entitled to any preemptive or subscription rights in respect of any
securities of the Corporation.

                  10. No Amendment or Impairment. The Corporation shall not
amend its Certificate of Incorporation or participate in any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, for the purpose of avoiding or seeking
to avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but will at all times in good faith
assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Series A Preferred Stock against impairment.

                  11. Severability of Provisions. Whenever possible, each
provision hereof shall be interpreted in a manner as to be effective and valid
under applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

                                  OF
                             MicroBio Inc.
                       (a Delaware corporation)

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

                              ARTICLE I

                             STOCKHOLDERS


     1. CERTIFICATES REPRESENTING STOCK. Certificates representing stock in
the corporation shall be signed by, or in the name of, the corporation by the
Chairman or Vice-Chairman of the Board of Directors, if any, or by the President
or a Vice-President and by the Treasurer or an Assistant Treasurer or the
Secretary or an Assistant Secretary of the corporation. Any or all the
signatures on any such certificate may be a facsimile. In case any officer,
transfer agent, or registrar who has signed or whose facsimile signature has
been placed upon a certificate shall have ceased to be such officer, transfer
agent, or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer, transfer agent, or
registrar at the date of issue.

     Whenever the corporation shall be authorized to issue more than one class
of stock or more than one series of any class of stock, and whenever the
corporation shall issue any shares of its stock as partly paid stock, the
certificates representing shares of any such class or series or of any such
partly paid stock shall set forth thereon the statements prescribed by the
General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.

     The corporation may issue a new certificate of stock or uncertificated
shares in place of any certificate theretofore issued by it, alleged to have
been lost, stolen, or destroyed, and the Board of Directors may require the
owner of the lost, stolen, or destroyed certificate, or his legal
representative, to give the corporation a bond sufficient to indemnify the
corporation against any claim that may be made against it on account of the
alleged loss, theft, or destruction of any such certificate or the issuance
of any such new certificate or uncertificated shares.

     2. UNCERTIFICATED SHARES. Subject to any conditions imposed by the General
Corporation Law, the Board of Directors of the corporation may provide by

                                    -1-

<PAGE>

resolution or resolutions that some or all of any or all classes or series of
the stock of the corporation shall be uncertificated shares. Within a reasonable
time after the issuance or transfer of any uncertificated shares, the
corporation shall send to the registered owner thereof any written notice
prescribed by the General Corporation Law.

     3. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be
required to, issue fractions of a share. If the corporation does not issue
fractions of a share, it shall (1) arrange for the disposition of fractional
interests by those entitled thereto, (2) pay in cash the fair value of fractions
of a share as of the time when those entitled to receive such fractions are
determined, or (3) issue scrip or warrants in registered form (either
represented by a certificate or uncertificated) or bearer form (represented by
a certificate) which shall entitle the holder to receive a full share upon the
surrender of such scrip or warrants aggregating a full share. A certificate
for a fractional share or an uncertificated fractional share shall, but scrip
or warrants shall not unless otherwise provided therein, entitle the holder to
exercise voting rights, to receive dividends thereon, and to participate in
any of the assets of the corporation in the event of liquidation. The Board
of Directors may cause scrip or warrants to be issued subject to the
conditions that they shall become void if not exchanged for certificates
representing the full shares or uncertificated full shares before a specified
date, or subject to the conditions that the shares for which scrip or warrants
are exchangeable may be sold by the corporation and the proceeds thereof
distributed to the holders of scrip or warrants, or subject to any other
conditions which the Board of Directors may impose.

     4. STOCK TRANSFERS. Upon compliance with provisions restricting the
transfer or registration of transfer of shares of stock, if any, transfers
or registration of transfers of shares of stock of the corporation shall be
made only on the stock ledger of the corporation by the registered holder
thereof, or by his attorney thereunto authorized by power of attorney duly
executed and filed with the Secretary of the corporation or with a transfer
agent or a registrar, if any, and, in the case of shares represented by
certificates, on surrender of the certificate or certificates for such shares
of stock properly endorsed and the payment of all taxes due thereon.

     5. RECORD DATE FOR STOCKHOLDERS. In order that the corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders or any adjournment thereof, the Board of Directors may fix a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which record
date shall not be more than sixty nor less than ten days before the date of such
meeting. If no record date is fixed by the Board of Directors, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the day
on which notice is given, or, if notice is waived, at the close of business on
the day next preceding the day on which the meeting is held. A determination of

                                    -2-

<PAGE>

stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.
In order that the corporation may determine the stockholders entitled to consent
to corporate action in writing without a meeting, the Board of Directors may
fix a record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining the stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is required
by the General Corporation Law, shall be the first date on which a signed
written consent setting forth the action taken or proposed to be taken is
delivered to the corporation by delivery to its registered office in the State
of Delaware, its principal place of business, or an officer or agent of the
corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.
If no record date has been fixed by the Board of Directors and prior action by
the Board of Directors is required by the General Corporation Law, the record
date for determining stockholders entitled to consent to corporate action in
writing without a meeting shall be at the close of business on the day on which
the Board of Directors adopts the resolution taking such prior action. In order
that the corporation may determine the stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion, or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty days prior to such action.
If no record date is fixed, the record date for determining stockholders for
any such purpose shall be at the close of business on the day on which the Board
of Directors adopts the resolution relating thereto.

     6. MEANING OF CERTAIN TERMS. As used herein in respect of the right to
notice of a meeting of stockholders or a waiver thereof or to participate or
vote thereat or to consent or dissent in writing in lieu of a meeting, as the
case may be, the term "share" or "shares" or "share of stock" or "shares of
stock" or "stockholder" or "stockholders" refers to an outstanding share or
shares of stock and to a holder or holders of record of outstanding shares of
stock when the corporation is authorized to issue only one class of shares of
stock, and said reference is also intended to include any outstanding share or
shares of stock and any holder or holders of record of outstanding shares of
stock of any class upon which or upon whom the certificate of incorporation
confers such rights where there are two or more classes or series of shares of
stock or upon which or upon whom the General Corporation Law confers such rights
notwithstanding that the certificate or incorporation may provide for more than
one class or series of shares of stock, one or more

                                    -3-

<PAGE>

of which are limited or denied such rights thereunder; provided, however, that
no such right shall vest in the event of an increase or a decrease in the
authorized number of shares of stock of any class or series which is otherwise
denied voting rights under the provisions of the certificate of incorporation,
except as any provision of law may otherwise require.

     7. STOCKHOLDER MEETINGS.

     -TIME. The annual meeting shall be held on the date and at the time fixed,
from time to time, by the directors, provided, that the first annual meeting
shall be held on a date within thirteen months after the organization of the
corporation, and each successive annual meeting shall be held on a date within
thirteen months after the date of the preceding annual meeting. A special
meeting shall be held on the date and at the time fixed by the directors.

     -PLACE. Annual meetings and special meetings shall be held at such place,
within or without the State of Delaware, as the directors may, from time to
time, fix. Whenever the directors shall fail to fix such place, the meeting
shall be held at the registered office of the corporation in the State of
Delaware.

     -CALL. Annual meetings and special meetings may be called by the
directors or by any officer instructed by the directors to call the meeting.

     -NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be
given, stating the place, date, and hour of the meeting and stating the place
within the city or other municipality or community at which the list of
stockholders of the corporation may be examined. The notice of an annual
meeting shall state that the meeting is called for the election of directors and
for the transaction of other business which may properly come before the
meeting, and shall (if any other action which could be taken at a special
meeting is to be taken at such annual meeting) state the purpose or purposes.
The notice of a special meeting shall in all instances state the purpose or
purposes for which the meeting is called. The notice of any meeting shall also
include, or be accompanied by, any additional statements, information, or
documents prescribed by the General Corporation Law. Except as otherwise
provided by the General Corporation Law, a copy of the notice of any meeting
shall be given, personally or by mail, not less than ten days nor more than
sixty days before the date of the meeting, unless the lapse of the prescribed
period of time shall have been waived, and directed to each stockholder at his
record address or at such other address which he may have furnished by request
in writing to the Secretary of the corporation. Notice by mail shall be deemed
to be given when deposited, with postage thereon prepaid, in the United States
Mail. If a meeting is adjourned to another time, not more than thirty days 
hence, and/or to another place, and if an announcement of the adjourned time 
and/or place is made at the meeting, it shall not be necessary to give notice 
of the adjourned meeting unless the directors, after adjournment, fix a new 
record date for

                                    -4-

<PAGE>

the adjourned meeting. Notice need not be given to any stockholder who submits
a written waiver of notice signed by him before or after the time stated
therein. Attendance of a stockholder at a meeting of stockholders shall
constitute a waiver of notice of such meeting, except when the stockholder
attends the meeting for the express purpose of objecting, at the beginning of
the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor
the purpose of, any regular or special meeting of the stockholders need be
specified in any written waiver of notice.

     -STOCKHOLDER LIST. The officer who has charge of the stock ledger of
the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city or other municipality or community
where the meeting is to be held, which place shall be specified in the notice
of the meeting, or if not so specified, at the place where the meeting is to
be held. The list shall also be produced and kept at the time and place of the
meeting during the whole time thereof, and may be inspected by any stockholder
who is present. The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by this
section or the books of the corporation, or to vote at any meeting of
stockholders.

     -CONDUCT OF MEETING. Meetings of the stockholders shall be presided over
by one of the following officers in the order of seniority and if present and
acting - the Chairman of the Board, if any, the Vice-Chairman of the Board,
if any, the President, a Vice-President, or, if none of the foregoing is in
office and present and acting, by a chairman to be chosen by the stockholders.
The Secretary of the corporation, or in his absence, an Assistant Secretary,
shall act as secretary of every meeting, but if neither the Secretary nor an
Assistant Secretary is present the Chairman of the meeting shall appoint a
secretary of the meeting.

     -PROXY REPRESENTATION. Every stockholder may authorize another person or
persons to act for him by proxy in all matters in which a stockholder is
entitled to participate, whether by waiving notice of any meeting, voting or
participating at a meeting, or expressing consent or dissent without a meeting.
Every proxy must be signed by the stockholder or by his attorney-in-fact. No
proxy shall be voted or acted upon after three years from its date unless such
proxy provides for a longer period. A duly executed proxy shall be irrevocable
if it states that it is irrevocable and, if, and only as long as, it is
coupled with an interest sufficient in law to support an irrevocable power.
A proxy may be

                                    -5-

<PAGE>

made irrevocable regardless of whether the interest with which it is coupled
is an interest in the stock itself or an interest in the corporation generally.

     -INSPECTORS. The directors, in advance of any meeting, may, but need not,
appoint one or more inspectors of election to act at the meeting or any
adjournment thereof. If an inspector or inspectors are not appointed, the
person presiding at the meeting may, but need not, appoint one or more
inspectors. In case any person who may be appointed as an inspector fails to
appear or act, the vacancy may be filled by appointment made by the directors
in advance of the meeting or at the meeting by the person presiding thereat.
Each inspector, if any, before entering upon the discharge of his duties, shall
take and sign an oath faithfully to execute the duties of inspectors at such
meeting with strict impartiality and according to the best of his ability.
The inspectors, if any, shall determine the number of shares of stock
outstanding and the voting power of each, the shares of stock represented at
the meeting, the existence of a quorum, the validity and effect of proxies,
and shall receive votes, ballots, or consents, hear and determine all challenges
and questions arising in connection with the right to vote, count and tabulate
all votes, ballots, or consents, determine the result, and do such acts as are
proper to conduct the election or vote with fairness to all stockholders. On
request of the person presiding at the meeting, the inspector or inspectors,
if any, shall make a report in writing of any challenge, question, or matter
determined by him or them and execute a certificate of any fact found by him
or them. Except as otherwise required by subsection (e) of Section 231 of the
General Corporation Law, the provisions of that Section shall not apply to the
corporation.

     -QUORUM. The holders of a majority of the outstanding shares of stock
shall constitute a quorum at a meeting of stockholders for the transaction
of any business. The stockholders present may adjourn the meeting despite the
absence of a quorum.

     -VOTING. Each share of stock shall entitle the holder thereof to one vote.
Directors shall be elected by a plurality of the votes of the shares present in
person or represented by proxy at the meeting and entitled to vote on the
election of directors. Any other action shall be authorized by a majority of
the votes cast except where the General Corporation Law prescribes a different
percentage of votes and/or a different exercise of voting power, and except as
may be otherwise prescribed by the provisions of the certificate of
incorporation and these Bylaws. In the election of directors, and for any other
action, voting need not be by ballot.

     8. STOCKHOLDER ACTION WITHOUT MEETINGS. Any action required by the General
Corporation Law to be taken at any annual or special meeting of stockholders, or
any action which may be taken at any annual or special meeting of stockholders,
may be taken without a meeting, without prior notice and without a vote, if a
consent in writing, setting forth the action so taken, shall be signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be

                                    -6-

<PAGE>

necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking
of the corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.
Action taken pursuant to this paragraph shall be subject to the provisions of
Section 228 of the General Corporation Law.

                                ARTICLE II

                                 DIRECTORS

     1. FUNCTIONS AND DEFINITION. The business and affairs of the corporation
shall be managed by or under the direction of the Board of Directors of the
corporation. The Board of Directors shall have the authority to fix the
compensation of the members thereof. The use of the phrase "whole board" herein
refers to the total number of directors which the corporation would have if
there were no vacancies.


     2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder, a
citizen of the United States, or a resident of the State of Delaware. The
initial Board of Directors shall consist of one person. Thereafter the number
of directors constituting the whole board shall be at least one. Subject to the
foregoing limitation and except for the first Board of Directors, such number
may be fixed from time to time by action of the stockholders or of the
directors, or, if the number is not fixed, the number shall be one. The number
of directors may be increased or decreased by action of the stockholders or of
the directors.

     3. ELECTION AND TERM. The first Board of Directors, unless the members
thereof shall have been named in the certificate of incorporation, shall be
elected by the incorporator or incorporators and shall hold office until the
first annual meeting of stockholders and until their successors are elected
and qualified or until their earlier resignation or removal. Any director
may resign at any time upon written notice to the corporation. Thereafter,
directors who are elected at an annual meeting of stockholders, and directors
who are elected in the interim to fill vacancies and newly created
directorships, shall hold office until the next annual meeting of stockholders
and until their successors are elected and qualified or until their earlier
resignation or removal. Except as the General Corporation Law may otherwise
require, in the interim between annual meetings of stockholders or of special
meetings of stockholders called for the election of directors and/or for the
removal of one or more directors and for the filling of any vacancy in that
connection, newly created directorships and any vacancies in the Board of
Directors, including unfilled vacancies resulting from the removal of directors
for cause or without cause, may be filled by the vote of a majority of the
remaining directors then in office, although less than a quorum, or by the sole
remaining director.

of Delaware as shall be fixed by the Board.

     -CALL. No call shall be required for regular meetings for which the time

regular meetings for which the time and place have been fixed. Written, oral,

thereat. Notice need not be given to any director or to any member of a
committee of directors who submits a written waiver of notice signed by him
before or after the time stated therein. Attendance of any such person at a
meeting shall constitute a waiver of notice of such meeting, except when he
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the directors need be specified in any
written waiver of notice.

     -QUORUM AND ACTION. A majority of the whole Board shall constitute a
quorum except when a vacancy or vacancies prevents such majority, whereupon
a majority of the directors in office shall constitute a quorum, provided,
that such majority shall constitute at least one-third of the whole Board.
A majority of the directors present, whether or not a quorum is present, may
adjourn a meeting to another time and place. Except as herein otherwise
provided, and except as otherwise provided by the General Corporation Law,
the vote of the majority of the directors present at a meeting at which a
quorum is present shall be the act of the Board. The quorum and voting
provisions herein stated shall not be construed as conflicting with any
provisions of the General Corporation Law and these Bylaws which govern a
meeting of directors held to fill vacancies and newly created directorships in
the Board or action of disinterested directors.

     Any member or members of the Board of Directors or of any committee
designated by the Board, may participate in a meeting of the Board, or any
such committee, as the case may be, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other.

majority of the whole Board, designate one or more committees, each committee

committees, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board, shall have
and may exercise the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation with the exception
of any authority the delegation of which is prohibited by Section 141 of the
General Corporation Law, and may authorize the seal of the corporation to be
affixed to all papers which may require it.

     7. WRITTEN ACTION. Any action required or permitted to be taken at any
meeting of the Board of Directors or any committee thereof may be taken without
a meeting if all members of the Board or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the Board or committee.

perform such additional duties as the Board shall assign to him. Any officer
may be removed, with or without cause, by the Board of Directors. Any vacancy
in any office may be filled by the Board of Directors.

jurisdiction within the State of

<PAGE>

Delaware may, on the application in a summary way of this  corporation or of any
creditor  or  stockholder  thereof,  or on the  application  of any  receiver or
receivers  appointed for this corporation under the provisions of section 291 of
Title 8 of the Delaware Code or on the application of trustees in dissolution or

civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including

taken or omitted in such capacity, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or on his behalf in connection with such action, suit or
proceeding and any appeal therefrom.

         Indemnification may include payment by the Corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the person indemnified to
repay such payment if it is ultimately determined that such person is not
entitled to indemnification under this Article, which undertaking may be
accepted without reference to the financial ability of such person to make such
repayment.

                                      -2-

Corporation.

The  indemnification  rights  provided  in this  Article  Ninth (i) shall not be
deemed exclusive of any other rights to which those  indemnified may be entitled
under any law,  agreement or vote of stockholders or disinterested  directors or

Corporation and such rights may be equivalent to, or greater or less than, those

                           CERTIFICATE OF DESIGNATION

                                       of

                            SERIES A PREFERRED STOCK

                                       of

                            ACUTE THERAPEUTICS, INC.

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware

     ACUTE THERAPEUTICS, INC., a corporation organized and existing under the
laws of the State of Delaware (the "Corporation"), does hereby certify that,
pursuant to the authority conferred on the Board of Directors of the Corporation
by the Certificate of Incorporation of the Corporation and in accordance with
Section 151 of the General Corporation Law of the State of Delaware, the Board
of Directors of the Corporation adopted the following resolution establishing a
series of 600,000 shares of Preferred Stock of the Corporation designated as
"Series A Preferred Stock":

          RESOLVED, that pursuant to the authority conferred on the Board
     of Director of this Corporation by the Certificate of Incorporation a
     series of Preferred Stock, par value $.001 per share, of the Corporation
     is hereby established and created, and that the designation and number
     of shares therefor and the voting and other powers, preferences and
     relative, participating, optional or other rights of the shares of such
     series and the qualifications, limitations and restrictions thereof are
     as follows:

<PAGE>

A. SERIES A PREFERRED STOCK.

     The Series A Preferred Stock shall have the following rights, preferences,
powers, privileges and restrictions, qualifications and limitations.

     1. Dividends.

              When and if the Board of Directors shall declare a dividend
payable with respect to the then outstanding shares of Common Stock of the
Corporation, the holders of the Series A Preferred Stock shall be entitled to
the amount of dividends per share as would be payable on the largest number of
whole shares of Common Stock into which each share of Series A Preferred Stock
could then be converted pursuant to Section 4 hereof (such number to be
determined as of the record date for the determination of holders of Common
Stock entitled to receive such dividend).

     2. Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations
        and Asset Sales.

              (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series
A Preferred Stock then outstanding shall be entitled to be paid out of the
assets of the Corporation available for distribution to its stockholders after
and subject to the payment in full of all amounts required to be distributed to
the holders of any other class or series of stock of the Corporation ranking on
liquidation prior and in preference to the Series A Preferred Stock
(collectively referred to as "Senior Preferred Stock"), but before any payment
shall be made to the holders of Common Stock or any other class or series of
stock ranking on liquidation junior to the Series A Preferred Stock (the Common
Stock and any other class or series of stock ranking on liquidation junior to
the Series A Preferred Stock being collectively referred to as "Junior Stock")
by reason of their ownership thereof, an amount equal to $12.50 per share
(subject to appropriate adjustment in the event of any stock dividend, stock
split, combination or other similar recapitalization affecting such shares),
plus any dividends declared or accrued but unpaid thereon. If upon any such
liquidation, dissolution or winding up of the Corporation the remaining assets
of the Corporation available for distribution to its stockholders shall be
insufficient to pay the holders of shares of Series A Preferred Stock the full
amount to which they shall be entitled, the holders of shares of Series A
Preferred Stock and any class or series of stock ranking on liquidation on a
parity with the Series A Preferred Stock shall share ratably in any distribution
of the remaining assets and funds of the Corporation in proportion to the
respective amounts which would otherwise be payable in respect of the shares
held by them upon such distribution if all amounts payable on or with respect to
such shares were paid in full.

              (b) After the payment of all preferential amounts required to
be paid to the holders of Senior Preferred Stock, Series A Preferred Stock
and any other class or series of stock of the Corporation ranking on liquidation
on a parity with the Series A Preferred Stock, upon the dissolution,
liquidation or winding up of the Corporation, the holders of shares of Junior
Stock then outstanding shall be entitled to receive the remaining assets and
funds of the Corporation available for distribution to its stockholders.

              (c) The consolidation or merger of the Corporation into or with
any other entity or entities or the consummation of any transaction or series
of transactions which results in either (i) the exchange by the holders of
outstanding shares of the Corporation of 50% or more of either (x) the then
outstanding shares of Common Stock or (y) the combined voting power of the
Corporation's then outstanding securities entitled to vote generally in the
election of directors or other general matters, (ii) the holders of outstanding
shares of the Corporation immediately prior to the consummation of such

<PAGE>
transaction or transactions holding less than 50% of the outstanding securities
of the resulting entity entitled to vote generally in the election of directors
or other general matters (either of (i) and (ii) being hereinafter referred to
as a "Change-in-Control Event") or (iii) the sale or transfer by the Corporation
of all or substantially all its assets (a "Consolidation Event"), shall be
deemed to be a liquidation, dissolution or winding up of the Corporation within
the meaning of the provisions of this Section 2. The consolidation or merger of
the Corporation into or with any entity or entities which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by any such entity
or affiliate thereof which does not result in a Change-of-Control Event or a
Consolidation Event shall not be deemed to be a liquidation, dissolution or
winding up of the Corporation within the meaning of the provisions of this
Section 2.

         3. Voting.

              (a) Each holder of outstanding shares of Series A Preferred
Stock shall be entitled to the number of votes equal to the number of
whole shares of Common Stock into which the shares of Series A Preferred Stock
held by such holder are then convertible (as adjusted from time to time pursuant
to Section 4 hereof), at each meeting of stockholders of the Corporation (and
written actions of stockholders in lieu of meetings) with respect to any and all
matters presented to the stockholders of the Corporation for their action or
consideration. Except as provided by law, by the provisions of Subsection 3(b)
below or by the provision establishing any other series of Preferred Stock,
holders of Series A Preferred Stock shall vote together with the holders of
Common Stock as a single class.

              (b) The Corporation shall not (i) amend, alter or repeal the
preferences, special rights or other powers of the Series A Preferred Stock so
as to affect adversely such series, or (ii) increase the authorized number of
shares of such series. In either case without the written consent or affirmative
vote of the holders of a majority of the then outstanding shares of such series,
given in writing or by vote at a meeting, commencing or voting (as the case may
be) separately as a class. For this purpose, without limiting the generality of
the foregoing, the authorization of any shares of capital stock with preference
or priority over Series A Preferred Stock as to the right to receive either
dividends or amounts distributable upon liquidation, dissolution or winding up
of the Corporation shall be deemed to affect adversely such series, and the
authorization of any shares of capital stock on a parity with such series as to
the right to receive either dividends or amounts distributable upon liquidation,
dissolution or winding up of the Corporation shall not be deemed to affect
adversely such series.

         4. Optional Conversion. The holders of the Series A Preferred Stock
shall have conversion rights as follows (the "Conversion Rights"):

              (a) Right to Convert. Each share of Series A Preferred Stock
shall be convertible, at the option of the holder thereof, at any time and
from time to time, and without the payment of additional consideration by the
holder thereof, into one (1) fully paid and nonassessable share of Common Stock
(the "Ratio"). The Ratio at which shares of Series A Preferred Stock may be
converted into shares of Common Stock shall be subject to adjustment as provided
below.

              In the event of a liquidation of the Corporation, the Conversion
Rights shall terminate at the close of business on the first full day preceding
the date fixed for the payment of any amounts distributable on liquidation to
the holders of Series A Preferred Stock.

              (b) Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of the Series A Preferred Stock. In lieu of
any fractional shares to which the holder would otherwise be entitled, the

<PAGE>

Corporation shall pay cash equal to such fraction multiplied by the then fair
market value of the Common Stock into which the Series A Preferred Stock is
being converted, as determined in good faith by the Board of Directors.

              (c) Mechanics of Conversion.

                   (i) In order for a holder of Series A Preferred Stock to
convert shares of Series A Preferred Stock into shares of Common Stock, such
holder shall surrender the certificate or certificates for such shares of Series
A Preferred Stock, at the office of the transfer agent for the Series A
Preferred Stock (or at the principal office of the Corporation if the
Corporation serves as its own transfer agent), together with written notice that
such holder elects to convert all or any number of the shares of the Series A
Preferred Stock represented by such certificate or certificates. Such notice
shall state such holder's name or the names of the nominees in which such holder
wishes the certificate or certificates for shares of Common Stock to be issued.
If required by the Corporation, certificates surrendered for conversion shall be
endorsed or accompanied by a written instrument or instruments of transfer, in
form satisfactory to the Corporation, duly executed by the registered holder or
his, her or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date"). The Corporation shall, as soon as practical after the
Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock, or to his, her or its nominees, a certificate or certificates
for the number of shares of Common Stock, to which such holder shall be
entitled, together with cash in lieu of any fraction of a share.

                   (ii) The Corporation shall at all times when the Series A
Preferred Stock shall be outstanding, reserve and keep available out of its
authorized but unissued stock, for the purpose of effecting the conversion of
the Series A Preferred Stock, such number of its duly authorize shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding Series A Preferred Stock.

                   (iii) Upon any such conversion, no adjustment to the Ratio
shall be made for any declared or executed buy unpaid dividends on the Series A
Preferred Stock surrendered for conversion or on the Common Stock delivered upon
conversion.

                   (iv) All shares of Series A Preferred Stock which shall have
been surrendered for conversion as herein provided shall no longer be deemed to
be outstanding and all rights with respect to such shares, including the rights,
if any, to receive notices and to vote, shall immediately cease and terminate on
the Conversion Date, except only the right of the holders thereof to receive
shares of Common Stock in exchange therefor and payment of any dividends
declared or accrued but unpaid thereon. Any shares of Series A Preferred Stock
so converted shall be retired and cancelled and shall not be redeemed, and the
Corporation (without the need for stockholder action) may from time to time take
such appropriate action as may be necessary to reduce the authorized Series A
Preferred Stock accordingly.

                   (v) The Corporation shall pay any and all issue and other
taxes that may be payable in respect of any issuance or delivery of shares of
Common Stock upon conversion of shares of Series A Preferred Stock pursuant to
this Section 4. The Corporation shall not, however, be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of shares of Common Stock in a name other than that in which the shares
of Series A Preferred Stock so converted were registered, and no such issuance
or delivery shall be made unless and until the person or

<PAGE>

early requesting such issuance has paid to the Corporation the amount of any
such tax or has established, to the satisfaction of the Corporation, that such
tax has been paid.

        (e)  Adjustment for Stock Splits and Combinations.  If the Corporation
shall at any time or from time to time after October 21, (the "Original Issue
Date") affect a subdivision of the outstanding Common Stock, the Ratio then in
effect immediately before that subdivision shall be proportionately described.
If the Corporation shall at any time or from time to time after the Original
Issue Date of the Series A Preferred Stock combine the outstanding shares of
Common Stock, the Ratio then in effect immediately before the combination
shall be proportionately increased.  Any adjustment under this paragraph
shall become effective at the close of business on the date the subdivision
or combination becomes effective.

        (a) Adjustment for Certain Dividends and Distributions.  In the event
the Corporation at any time, or from time to time after the Original Issue Date
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
additional shares of Common Stock, then and in each such event the Ratio for
the Series A Preferred Stock then in effect shall be decreased as of the time
of such issuance or, in the event such a record date shall have been fixed, as
of the close of business on such record date, by multiplying the Ratio for the
Series A Preferred Stock then in effect by a fraction:

        (1)  the numerator of which shall be the total number of shares of
Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date, and

        (2) the denominator of which shall be the total number of shares of
Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution;

provided, however; if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
thereafter, the Ratio for the Series A Preferred Stock shall be recomputed
accordingly as of the close of business on such record date and thereafter
the Ratio for the Series A Preferred Stock shall be adjusted pursuant to this
paragraph as of the time of actual payment of such dividends or distributions.

        (f) Adjustments for Other Dividends and Distributions.  In the event
the Corporation at any time or from time to time after the Original Issue Date
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Corporation other than shares of Common Stock, then and in
each such event provision shall be made so that the holders of Series A
Preferred Stock shall receive upon conversion thereof in addition to the
number of shares of Common Stock receivable thereupon, the amount of securities
of the Corporation that they would have received had the Series A Preferred
Stock been converted into Common Stock on the date of such event and had
thereafter, during the period from the date of such event to and including
the conversion date, retained such securities receivable by them as aforesaid
during such period, giving application to all adjustments called for during
such period under this paragraph with respect to the rights of the holders
of Series A Preferred Stock.

        (g)  Adjustment for Reclassification, Exchange or Substitution.  If
the Common Stock issuable upon the conversion of the Series A Preferred Stock
shall be changed into the same or a different number of shares of any class
or classes of stock, whether by capital reorganization, reclassification, or
otherwise (other than a subdivision or combination of shares or stock dividend
provided for above, or a reorganization, merger, consolidation, or sale of
assets provided for below), then and in each such event the holders of Series A
Preferred Stock shall have the right thereafter to convert such share into the
kind and amount of shares of stock and other securities and property receivable
upon such reorganization, reclassification, or other change, by holders of the
number of shares of Common Stock into which such shares of Series A Preferred
Stock might have been converted immediately prior to such reorganization,
reclassification, or change, all subject to further adjustment as provided
herein.

        (h)  Adjustment for Merger or Reorganization, etc.  In case of any
consolidation or merger of the Corporation with or into another corporation
or the sale of all or substantially all of the assets of the Corporation to
another corporation (other than a consolidation, merger or sale which is
covered by Subsection 2(e)), each share of Series A Preferred Stock shall
thereafter be convertible (or shall be converted into a security which shall
be convertible) into the kind and amount of shares of stock or other securities
or property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such Series A Preferred Stock would
have been entitled upon such consolidation, merger or sale; and, in such case,
appropriate adjustment (as determined in good faith by the Board of Directors)
shall be made in the application of the provisions in this Section 4 set forth
with respect to the rights and interest thereafter of the holders of the 
Series A Preferred Stock, to the end that the provisions set forth in 
this Section 4 (including provisions with respect to changes 
in and other adjustments of the Ratio) shall thereafter be applicable, 
as nearly as reasonably may be, in relation to any shares of stock or other 
property thereafter deliverable upon the conversion of the Series A 
Preferred Stock.

        (i)  No Impairment.  The Corporation will not, by amendment of its
Restated Certificate of Incorporation or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Corporation,
but will at all times in good faith assist in the carrying out of all the
provisions of this Section 4 and in the taking of all such action as may be
necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A Preferred Stock against impairment.

        5.  Status of Acquired Shares.  All shares of Series A Preferred Stock
which shall have been surrendered for conversion as herein provided shall no
longer be deemed to be outstanding and all rights with respect to such shares,
including the rights, if any, to receive notices and to vote, shall immediately
cease and terminate on the Conversion Date, except only the right of the holders
thereof to receive shares of Common Stock in exchange therefor and payment of
any dividends declared but unpaid thereon.  Any shares of Series A Preferred
Stock so converted shall be retired and cancelled and shall not be released,
and the Corporation (without the need for stockholder action) may from time
to time take such appropriate action as may be necessary to reduce the
authorized Series A Preferred Stock accordingly.

        6.  Preemptive Rights.  The Series A Convertible Preferred Stock is
not entitled to any preemptive or subscription rights in respect of any
securities of the Corporation.

        7.  No Amendment or Impairment.  The Corporation shall not amend its
Certificate of Incorporation or participate in any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, for the purpose of avoiding or seeking to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but will on all issues in good faith
assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Series A Preferred Stock against impairment.

        8.  Invalidity of Provisions.  Whenever possible, each provision
hereof shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a part of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were improved or dissolved, then such officer may make such
change as shall be necessary to render the provisions in question effective
and valid under applicable law.

                                       of
                            SERIES B PREFERRED STOCK

                         Pursuant to  Section 151 of the
                General Corporation Law of the State of Delaware

     ACUTE THERAPEUTICS, INC., a corporation organized and existing under the
laws of the State of Delaware (the "Corporation"), does hereby certify that,
pursuant to the authority conferred on the Board of Directors of the
Corporation by the Certificate of Incorporation of the Corporation and in
accordance with Section 151 of the General Corporation Law of the State of
Delaware, the Board of Directors of the Corporation adopted the following
resolution establishing a series of 2,200 shares of Preferred Stock of the
Corporation designated as "Series B Preferred Stock";

     RESOLVED, that pursuant to the authority conferred on the Board of
  Directors of this Corporation by the Certificate of Incorporation a series
  of Preferred Stock, par value $.001 per share, of the Corporation is hereby
  established and created, and that the designation and number of shares
  thereof and the voting and other powers, preferences and relative,
  participating, optional or other rights of the shares of such series and
  the qualifications, limitations and restrictions thereof are as follows:


<PAGE>

     The Series B Preferred Stock shall have the following rights, preferences,
powers, privileges and restrictions, qualifications and limitations.

     1. Dividends.

        The holders of shares of Series B Preferred Stock shall be entitled
to receive, out of funds legally available therefor, dividends at the rate of
$100 per share per annum (subject to appropriate adjustment in the event of any
stock dividend, stock split, combination or other similar recapitalization
affecting such shares) prior to and in preference to any declaration or payment
of any dividend on the Junior Stock (as defined below). Such dividends shall be
cumulative from the date of issuance of each share of Series B Preferred Stock
and shall accrue annually; provided, however, that such dividends shall be due
and payable only upon and in the event of (i) a liquidation dissolution or
winding up of the Corporation under Section 2(a) hereof, or (ii) the redemption
of the Series B Preferred Stock pursuant to Section 4 hereof.

     2. Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations
        and Asset Sales.

        (a) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series
B Preferred Stock then outstanding shall be entitled to be paid out of the
assets of the Corporation available for distribution to its stockholders after
and subject to the payment in full of all amounts required to be distributed to
the holders of any other class or series of stock of the Corporation ranking
on liquidation prior and in preference to the Series B Preferred Stock
(collectively referred to as "Senior Preferred Stock"), but before any payment
shall be made to the holders of Common Stock, the Series A Preferred Stock,
or any other class or series of stock ranking on liquidation junior to the
Series B Preferred Stock (the Common Stock, the Series A Preferred Stock and
any other class or series of stock ranking on liquidation junior to the Series
B Preferred Stock being collectively referred to as "Junior Stock") by reason
of their ownership thereof, an amount equal to $1000 per share (subject
to appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization affecting such shares), plus
any dividends declared or accrued but unpaid thereon. If upon any such
liquidation, dissolution or winding up of the Corporation the remaining assets
of the Corporation available for distribution to its stockholders shall be
insufficient to pay the holders of shares of Series B Preferred Stock the full
amount to which they shall be entitled, the holders of shares of Series B
Preferred Stock and any class or series of stock ranking on liquidation on a
parity with the Series B Preferred Stock shall share ratably in any
distribution of the remaining assets and funds of the Corporation in proportion
to the respective amounts which would otherwise be payable in respect of the
shares held by them upon such distribution if all amounts payable on or with
respect to such shares were paid in full.

        (b) After the payment of all preferential amounts required to be paid
to the holders of Senior Preferred Stock, Series B Preferred Stock and any
other class or series of stock of the Corporation ranking on liquidation on
a parity with the Series B Preferred Stock, upon the dissolution, liquidation or

                                   -2-

<PAGE>

winding up of the Corporation, the holders of shares of Junior Stock then
outstanding shall be entitled to receive the remaining assets and funds of the
Corporation available for distribution to its stockholders.

        (c) The consolidation or merger of the Corporation into or with any
other entity or entities or the consummation of any transaction or series of
transactions which results in either (i) the exchange by the holders of
outstanding shares of the Corporation of 50% or more of either (x) the then
outstanding shares of Common Stock or (y) the combined voting power of the
Corporation's then outstanding securities entitled to vote generally in the
election of directors or other general matters, (ii) the holders of outstanding
shares of the Corporation immediately prior to the consummation of such
transaction or transactions holding less than 50% of the outstanding securities
of the resulting entity entitled to vote generally in the election of directors
or other general matters (either of (i) and (ii) being hereinafter referred
to as a "Change-in-Control Event") or (iii) the sale or transfer by the
Corporation of all or substantially all its assets (a "Consolidation Event"),
shall be deemed to be a liquidation, dissolution or winding up of the
Corporation within the meaning of the provisions of this Section 2. The
consolidation or merger of the Corporation into or with any entity or entities
which results in the exchange of outstanding shares of the Corporation for
securities or other considerations issued or paid or caused to be issued or
paid by any such entity or affiliate thereof which does not result in a Change-
of-Control Event or a Consolidation Event shall not be deemed to be a
liquidation, dissolution or winding up of the Corporation within the meaning
of the provisions of this Section 2.

     3. Voting Rights Except as required by law, the Series B Preferred Stock
shall not have any voting rights with respect to any matters presented to the
stockholders of the Corporation for their action or consideration.

     4. Mandatory Redemption

        (a) The Corporation will, upon the first to occur of (i) the approval
of the first New Drug Application filed by the Corporation relating to or
incorporating the KL4-Surfactant approved by the United States Food and Drug
Administration or (ii) the closing of an initial public offering of the
Corporation's Common Stock (the "Mandatory Redemption Date"), redeem from
each holder of shares of Series B Preferred Stock, at a price equal to $1000
per share, plus any dividends declared or accrued but unpaid thereon, subject
to appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization affecting such shares, all of the
outstanding shares of Series B Preferred Stock held by such holder on the
applicable Mandatory Redemption Date payable, at the option of the Corporation,
either (1) in cash, or (2) if (and only if) the Corporation's Common Stock
is publicly quoted on a national securities exchange or otherwise (as more
fully described below), in shares of Common Stock valued at the Current
Market Price. The "Current Market Price" of the Company's Common Stock
shall be determined as follows: (a) with respect to an event under clause
(ii) above, the Current Market Price shall be price per share paid by the
public in such initial public offering or (b) with respect to an event under
clause (i) above the Current Market Price shall mean the average closing
price for the Corporation's Common Stock for the twenty (20) consecutive
business day period ending as of the date three (3) business days prior
to the Mandatory Redemption Date whether or not the sale price of the
Common Stock was reported on any business day on the trading day immediately
preceding the date of such determination. The closing price shall be the
reported sales price regular way, in each case

                                       -3-

<PAGE>

on the principal national securities exchange or the Nasdaq National Market
System on which the shares of the Corporation's Common Stock are listed or
admitted to trading, or if not listed or admitted to trading thereon, the
average of the closing bid and asked prices of the Common Stock in the
over-the-counter market as reported by Nasdaq or any comparable system, or
if the Common Stock is not listed on Nasdaq or a comparable system, the
average of the closing bid and asked prices on such day in the domestic
over-the-counter market as reported on the NASD Electronic Bulletin Board,
or, if not reported on such bulletin board, in the "pink-sheets" published
by the National Quotation Bureau, Incorporated.

     (b) If the funds of the Corporation legally available for redemption
of Series B Preferred Stock on any Mandatory Redemption Date are insufficient
to redeem the number of shares of Series B Preferred Stock required under this
Section 4 to be redeemed on such date, those funds which are legally available
will be used to redeem the maximum possible number of such shares of Series B
Preferred Stock ratably on the basis of the number of shares of Series B
Preferred Stock which would be redeemed on such date if the funds of the
Corporation legally available therefor had been sufficient to redeem all shares
of Series B Preferred Stock required to be redeemed on such date. At any time
thereafter when additional funds of the Corporation become legally available
for the redemption of Series B Preferred Stock, such funds will be used, at the
end of the next succeeding fiscal quarter, to redeem the balance of the shares
which the Corporation was theretofore obligated to redeem, ratably on the basis
set forth in the preceding sentence.

     (c) The Corporation shall provide notice of any redemption of Series B
Preferred Stock pursuant to this Section 4 specifying the time and place of
redemption and the Mandatory Redemption Price, by first class or registered
mail, postage prepaid, to each holder of record of Series B Preferred Stock
at the address for such holder last shown on the records of the transfer
agent therefor (or the records of the Corporation, if it serves as its own
transfer agent), not more than 60 nor less than 30 days prior to the date on
which such redemption is to be made. If less than all Series B Preferred
Stock owned by such holder is then to be redeemed, the notice will also
specify the number of shares which are to be redeemed. Upon mailing any
such notice of redemption, the Corporation will become obligated to redeem
at the time of redemption specified therein all Series B Preferred Stock
specified therein.

     (d) Unless there shall have been a default in payment of the Mandatory
Redemption Price, no share of Series B Preferred Stock shall be entitled
to any dividends declared after its Mandatory Redemption Date, and on such
Mandatory Redemption Date all rights of the holder of such share as a
stockholder of the Corporation by reason of the ownership of such share
will cease, except the right to receive the Mandatory Redemption Price of
such share, without interest, upon presentation and surrender of the
certificate representing such share, and such share will not from and after
such Mandatory Redemption Date be deemed to be outstanding.

     (e) Any Series B Preferred Stock redeemed pursuant to this Section 4
will be cancelled and will not under any circumstances be reissued, sold or
transferred and the Corporation may from time to time take such appropriate
action as may be necessary to reduce the authorized Series B Preferred Stock
accordingly.

                                    -4-

<PAGE>


     5. No Conversion Rights. The Series B Preferred Stock shall have
no rights of conversion in respect of any securities of the Corporation.

     6. No Reissuance of Series B Preferred Stock. No share or shares of Series
B Preferred Stock acquired by the Corporation by reason of redemption, purchase
or otherwise shall be reissued, and all such shares shall be cancelled, retired
and eliminated from the shares which the Corporation shall be authorized to
issue.

     7. Redemptive Rights. The Series B Preferred Stock is not entitled to
any preemptive or subscription rights in respect of any securities of the
Corporation.

     8. Reorganizations and Recapitalizations. If at any time or from time to
time there shall be a reorganization or recapitalization of the Common Stock,
then, as a condition of such reorganization or recapitalization, provision shall
be made so that the holders of the Series B Preferred Stock shall thereafter
be entitled to receive in exchange for the Series B Preferred Stock the
number of shares of stock or other securities or property of the corporation
or otherwise, to which a holder of Common Stock deliverable upon redemption
would have been entitled on such reorganization or recapitalization.

     9. Notice of Record Date. In the event of any taking by the Corporation
of a record of the holders of any class of securities for the purpose of
determining the holder thereof who are entitled to receive any dividend or
other distribution, any right to subscribe for, purchase or otherwise acquire
any shares of stock of any class or any other securities or property, or to
receive any other right, the corporation shall mail to each holder of Series
B Preferred Stock, at least twenty (20) days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of any dividend (other than a cash dividend) or other distribution,
any right to such dividend, distribution or right.

     10. No Amendment or Impairment. The Corporation shall not amend its
Certificate of Incorporation or participate in any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, for the purpose of avoiding or seeking to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but will at all times in good faith
assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Series B Preferred Stock against impairment.

     11. Protective Provisions. So long as any shares of Series B Preferred
Stock are outstanding, the Corporation shall not, without first obtaining
the approval (by vote or written consent, as provided by law) by majority
vote of the Board of Directors and of the holders of at least a majority
of the outstanding shares of the Series B Preferred Stock:

        (a) amend or repeal any provisions of the Corporation's Certificate
Incorporation or Bylaws which in any manner adversely affects the holders of
Series B Preferred Stock; or


                                     -5-
<PAGE>

         (b) Alter or change the designations, powers, rights, preferences
or privileges, or the qualifications. limitations or restrictions of the
Series B Preferred Stock; or

         (c) Increase the authorized number of shares of Series B Preferred
Stock; or

         (d) Authorize, create or issue any class or series of stock or any
other securities convertible into equity securities of the corporation having
a preference over, or being on a party with, the Series B Preferred Stock
with respect to dividends, redemptions or upon liquidation or dissolution
of the corporation; or

         (e) Reclassify the shares of Common Stock or any other shares of any
class or series of capital stock hereafter created junior to the Series B
Preferred Stock into shares of any class or series of capital stock
(i) ranking either as to payment of dividends, distributions of assets or
redemptions, prior to or on parity with the Series B Preferred Stock, or
(ii) which in any manner adversely affects the holders of Series B
Preferred Stock.

     12. Severability of Provisions. Whenever possible, each provision
hereof shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provisions hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating or
otherwise adversely affecting the remaining provisions hereof. If a court of
competent jurisdiction should determine that a provision hereof would be
valid or enforceable if a period of time were extended or shortened or a
particular percentage were increased or decreased, then such court may
make such change as shall be necessary to render the provision in question
effective and valid under applicable law.

                            ARTICLE 1 - Stockholders

     1.1 Place of Meeting. All meetings of stockholders shall be held at such
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the
registered office of the corporation.

     1.2 Annual Meeting. The annual meeting of stockholders for the election of
directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors or the President (which date shall not be a legal holiday in the place
where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting. If no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-Laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

     1.3 Special Meeting. Special meetings of stockholders may be called at any
time by the President or by the Board of Directors. Business transacted at any
special meeting of stockholders shall be limited to matters relating to the
purpose or purposes stated in the notice of meeting.

     1.4 Notice of Meetings. Except as otherwise provided by law, written notice
of each meeting of stockholders, whether annual or special, shall be given not
less than 10 nor more than 60 days before the date of the meeting to each
stockholder entitled to vote at such meeting. The notices of all meetings shall
state the place, date and hour of the meeting. The notice of a special meeting
shall state, in addition, the purpose or purposes for which the meeting is
called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

     1.5 Voting List. The officer who has charge of the stock ledger of the
corporation shall prepare, at least 10 days before every meeting of
stockholders, a complete

<PAGE>

list  of  the  stockholders  entitled  to  vote  at  the  meeting,  arranged  in
alphabetical order and showing the address of each stockholder and the number of
shares  registered in the name of each  stockholder.  Such list shall be open to
the  examination  of any  stockholder,  for any purpose  germane to the meeting,
during ordinary  business  hours,  for a period of at least 10 days prior to the
meeting,  at a place  within the city where the meeting is to be held.  The list
shall also be produced and kept at the time and place of the meeting  during the
whole  time of the  meeting,  and may be  inspected  by any  stockholder  who is
present.

     1.6 Quorum. Except as otherwise provided by law, the Certificate of
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

     1.7 Adjournments. Any meeting of stockholders may be adjourned to any other
time and to any other place at which a meeting of stockholders may be held under
these By-Laws by the stockholders present or represented at the meeting and
entitled to vote, although less than a quorum, or, if no stockholder is present,
by any officer entitled to preside at or to act as Secretary of such meeting. It
shall not be necessary to notify any stockholder of any adjournment of less than
30 days if the time and place of the adjourned meeting are announced at the
meeting at which adjournment is taken, unless after the adjournment a new record
date is fixed for the adjourned meeting. At the adjourned meeting, the
corporation may transact any business which might have been transacted at the
original meeting.

     1.8 Voting and Proxies. Each stockholder shall have one vote for each share
of stock entitled to vote held of record by such stockholder and a proportionate
vote for each fractional share so held, unless otherwise provided in the
Certificate of Incorporation. Each stockholder of record entitled to vote at a
meeting of stockholders, or to express consent or dissent to corporate action in
writing without a meeting, may vote or express such consent or dissent in person
or may authorize another person or persons to vote or act for him by written
proxy executed by the stockholder or his authorized agent and delivered to the
Secretary of the corporation. No such proxy shall be voted or acted upon after
three years from the date of its execution, unless the proxy expressly provides
for a longer period.

     1.9 Action at Meeting. When a quorum is present at any meeting, the holders
of shares of stock representing a majority of the votes cast on a matter (or if
there are two or more classes of stock entitled to vote as separate classes,
then in the case of each such class, the holders of shares of stock of that
class representing a majority of the votes cast on a matter) shall decide any
matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws. When a quorum is present at any meeting, any
election by stockholders shall be determined by a plurality of the votes cast on
the election.

                                      -2-
<PAGE>


     1.10 Action without Meeting. Any action required or permitted to be taken
at any annual or special meeting of stockholders of the corporation may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such action were present and voted. Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.

                             ARTICLE 2 - Directors

     2.1 General Powers. The business and affairs of the corporation shall be
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

     2.2 Number; Election and Qualification. The number of directors which shall
constitute the whole Board of Directors shall be determined by resolution of the
stockholders or the Board of Directors, but in no event shall be less than one.
The number of directors may be decreased at any time and from time to time
either by the stockholders or by a majority of the directors then in office, but
only to eliminate vacancies existing by reason of the death, resignation,
removal or expiration of the term of one or more directors. The directors shall
be elected at the annual meeting of stockholders by such stockholders as have
the right to vote on such election. Directors need not be stockholders of the
corporation.

     2.3 Enlargement of the Board. The number of directors may be increased at
any time and from time to time by the stockholders or by a majority of the
directors then in office.

     2.4 Tenure. Each director shall hold office until the next annual meeting
and until his successor is elected and qualified, or until his earlier death,
resignation or removal.

     2.5 Vacancies. Unless and until filled by the stockholders, any vacancy in
the Board of Directors, however occurring, including a vacancy resulting from an
enlargement of the Board, may be filled by vote of a majority of the directors
then in office, although less than a quorum, or by a sole remaining director. A
director elected to fill a vacancy shall be elected for the unexpired term of
his predecessor in office, and a director chosen to fill a position resulting
from an increase in the number of directors shall hold office until the next
annual meeting of stockholders and until his successor is elected and qualified,
or until his earlier death, resignation or removal.

                                       -3-


     2.6 Resignation. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

     2.7 Regular Meetings. Regular meetings of the Board of Directors may be
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination. A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

     2.8 Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

     2.9 Notice of Special Meetings. Notice of any special meeting of directors
shall be given to each director by the Secretary or by the officer or one of the
directors calling the meeting. Notice shall be duly given to each director (i)
by giving notice to such director in person or by telephone at least 48 hours in
advance of the meeting, (ii) by sending a telegram or telex, or delivering
written notice by hand, to his last known business or home address at least 48
hours in advance of the meeting, or (iii) by mailing written notice to his last
known business or home address at least 72 hours in advance of the meeting. A
notice or waiver of notice of a meeting of the Board of Directors need not
specify the purposes of the meeting.

     2.10 Meetings by Telephone Conference Calls. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

     2.11 Quorum. A majority of the total number of the whole Board of Directors
shall constitute a quorum at all meetings of the Board of Directors. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each such director so
disqualified; provided, however, that in no case shall less than one-third (1/3)
of the number so fixed constitute a quorum. In the absence of a quorum at any
such meeting, a majority of the directors present may adjourn the meeting from
time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

                                      -4-
<PAGE>


     2.12 Action at Meeting. At any meeting of the Board of Directors at which a
quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a different vote is specified by law, the Certificate
of Incorporation or these By-Laws.

     2.13 Action by Consent. Any action required or permitted to be taken at any
meeting of the Board of Directors or of any committee of the Board of Directors
may be taken without a meeting, if all members of the Board or committee, as the
case may be, consent to the action in writing, and the written consents are
filed with the minutes of proceedings of the Board or committee.

     2.14 Removal. Except as otherwise provided by the General Corporation Law
of Delaware, any one or more or all of the directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors, except that the directors elected by the holders of
a particular class or series of stock may be removed without cause only by vote
of the holders of a majority of the outstanding shares of such class or series.

     2.15 Committees. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members of the committee present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Any such committee, to the extent
provided in the resolution of the Board of Directors and subject to the
provisions of the General Corporation Law of the State of Delaware, shall have
and may exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation and may authorize the
seal of the corporation to be affixed to all papers which may require it. Each
such committee shall keep minutes and make such reports as the Board of
Directors may from time to time request. Except as the Board of Directors may
otherwise determine, any committee may make rules for the conduct of its
business, but unless otherwise provided by the directors or in such rules, its
business shall be conducted as nearly as possible in the same manner as is
provided in these By-Laws for the Board of Directors.

     2.16 Compensation of Directors. Directors may be paid such compensation for
their services and such reimbursement for expenses of attendance at meetings as
the Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.

majority of the entire number of directors then in office.

resigns or is removed shall have any right to any compensation as an officer for
any period following his resignation or removal, or any right to damages on
account of such removal, whether his compensation be by the month or by the year
or otherwise, unless such compensation is expressly provided in a duly
authorized written agreement with the corporation.

office for any reason and may, in its discretion, leave unfilled for such period
as it may determine any offices other than those of President, Treasurer and

on transfer pursuant to the Certificate of Incorporation, the By-Laws,
applicable securities laws or any agreement among any number of shareholders or
among such holders and the corporation shall have conspicuously noted on the
face or back of the certificate either the full text of the restriction or a
statement of the existence of such restriction.

     4.3 Transfers. Except as otherwise established by rules and regulations
adopted by the Board of Directors, and subject to applicable law, shares of
stock may be transferred on the books of the corporation by the surrender to the
corporation or its transfer agent of the certificate representing such shares

properly executed, and with such proof of authority or the authenticity of
signature as the corporation or its transfer agent may reasonably require.
Except as may be otherwise required by law, by the Certificate of Incorporation
or by these By-Laws, the corporation shall be entitled to treat the record
holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect

stock until the shares have been transferred on the books of the corporation in

     4.4 Lost, Stolen or Destroyed Certificates. The corporation may issue a new
certificate of stock in place of any previously issued certificate alleged to
have been lost, stolen, or destroyed, upon such terms and conditions as the
Board of Directors may prescribe, including the presentation of reasonable
evidence of such loss, theft or destruction and the giving of such indemnity as
the Board of Directors may require for the protection of the corporation or any
transfer agent or registrar.

     4.5 Record Date. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action. Such record date shall not be more than 60 nor less than 10 days before
the date of such meeting, nor more than 60 days prior to any other action to
which such record date relates.

     If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given, or, if
notice is waived, at the close of business on the day before the day on which
the meeting is held. The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the Board of Directors is necessary, shall be the day on which the
first written consent is expressed. The record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating to such purpose.

                                       -9-

<PAGE>

     A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

                          ARTICLE 5 - Indemnification

     The corporation may, to the fullest extent authorized under the laws of the
State of Delaware, as those laws may be amended and supplemented from time to
time, indemnify any director, officer, employee and/or agent made, or threatened
to be made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director, officer and/or
employee of the corporation or a predecessor corporation or, at the
corporation's request, a director or officer of another corporation, provided,
however, that the corporation shall indemnify any such agent in connection with
a proceeding initiated by such agent only if such proceeding was authorized by
the Board of Directors of the corporation. The indemnification provided for in
this Article 5 shall: (i) not be deemed exclusive of any other rights to which
those indemnified may be entitled under any bylaw, agreement or vote of
stockholders or disinterested directors or otherwise, both as to action in their
official capacities and as to action in another capacity while holding such
office, (ii) continue as to a person who has ceased to be a director, officer,
employee and/or agent, as the case may be, and (iii) inure to the benefit of the
heirs, executors and administrators of such a person. The corporation's
obligation to provide indemnification under this Article 5 shall be offset to
the extent of any other source of indemnification or any otherwise applicable
insurance coverage under a policy maintained by the corporation or any other
person.

     Expenses incurred by a director of the corporation in defending a civil or
criminal action, suit or proceeding by reason of the fact that he is or was a
director of the corporation (or was serving at the corporation's request as a
director or officer of another corporation) shall be paid by the corporation in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director to repay such amount if it
shall ultimately be determined that he is not entitled to be indemnified by the
corporation as authorized by relevant sections of the General Corporation Law of
Delaware. Notwithstanding the foregoing, the corporation shall not be required
to advance such expenses to an agent who is a party to an action, suit or
proceeding brought by the corporation and approved by a majority of the Board of
Directors of the corporation which alleges willful misappropriation of corporate
assets by such agent, disclosure of confidential information in violation of
such agent's fiduciary or contractual obligations to the corporation or any
other willful and deliberate breach in bad faith of such agent's duty to the
corporation or its stockholders.

     The foregoing provisions of this Article 5 shall be deemed to be a contract
between the corporation and each director who serves in such capacity at any
time while this bylaw is in effect, and any repeal or modification thereof shall
not affect any rights or obligations then
                                      -10-

<PAGE>

existing with respect to any state of facts then or theretofore  existing or any
action,  suit or proceeding  theretofore or thereafter brought based in whole or
in part upon any such state of facts.

     The Board of Directors in its discretion shall have power on behalf of the
corporation to indemnify any person, other than a director, made a party to any
action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.

     To assure indemnification under this Article 5 of all directors, officers
and employees who are determined by the corporation or otherwise to be or to
have been "fiduciaries" of any employee benefit plan of the corporation which
may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Article 5, be interpreted as follows:

               INVENTORY TRANSFER/STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made this 28th day of October, 1996, by and between 
ACUTE THERAPEUTICS, INC., a Delaware corporation (the "Company"), JOHNSON & 
JOHNSON DEVELOPMENT CORPORATION, a New Jersey corporation ("JJDC") and THE 
R.W. JOHNSON PHARMACEUTICAL RESEARCH INSTITUTE, a division of ORTHO 
PHARMACEUTICAL CORPORATION, a Delaware corporation (the "Transferor").

     WHEREAS, Transferor has agreed to transfer to the Company its existing
raw material inventory relating to KL4-Surfactant and dedicated equipment used 
in the formulation of KL4-Surfactant (as listed on Schedule A and Schedule B

40,000 shares of the Company's common stock, $0.001 par value per share (the
"Common Stock") and 2,200 shares of the Company's Non-Voting Non-Convertible 
Series B Preferred Stock, $0.001 par value per share (the "Series B Preferred

collectively referred to as the "Shares") which Shares shall be issued to 
Transferor's affiliate, JJDC;

     WHEREAS, the Company wishes to acquire the Inventory and Equipment in 
consideration of the issuance and sales of the Shares; and

forth and other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

<PAGE>

registered in the name of JJDC for 2,200 shares of Series B Preferred Stock.

     3. Representations and Warranties of Transferor or JJDC.

     Transferor or JJDC hereby represents and warrants, as to itself only to 
the extent indicated below, to the Company that:

        a. Authorization. Transferor or JJDC has full corporate power and 
authority to enter into and perform its obligations under this Agreement, the 
Registration Rights Agreement attached as Exhibit A hereto (the "Registration 
Rights Agreement") and the Co-Sale Agreement attached as Exhibit B hereto (the 
"Co-Sale Agreement"), and each such Agreement constitutes a valid and legally 
binding obligation of Transferor and/or JJDC, enforceable in accordance with 
its terms except (i) as limited by applicable bankruptcy, insolvency, 
reorganization, moratorium and other laws of general application affecting 
enforcement of creditors' rights generally and (ii) as limited by laws relating
to the availability of specific performance, injunctive relief, or other 
equitable remedies.

        b. Title to Inventory and Equipment. Transferor has good and marketable
title to the Inventory and Equipment free and clear of all easements, 
mortgages, pledges, liens, encumbrances, security interests, equities, charges,
claims, clouds and restrictions of any nature whatsoever (collectively, 
"Liens").

        c. Inventory. Schedule A hereto sets forth a complete and accurate list
and description of the Inventory, which constitutes all inventory owned by 
Transferor with respect to its research and development program for the 
formulation of KL4-Surfactant.

        d. Equipment. Schedule B hereto sets forth a complete and accurate list
and description of the Inventory, which constitutes all equipment owned by 
Transferor with respect to its research and development program for the 
formulation of KL4-Surfactant.

        e. Third Party Consents. No consent, approval, or authorization of any 
third party on the part of Transferor is required in connection with the 
transfer of the Inventory and Equipment as contemplated by this Agreement.

        f. Investment Representations.

           (i) Investment Intent. This Agreement is made with Transferor in 
reliance upon its representation to the Company, which by acceptance hereof 
Transferor confirms, that the Shares have been acquired with Transferor's 
own assets for investment for the account of its affiliate, JJDC, not as a 
nominee or agent, and not with a view to the sale or distribution of any part 
thereof, and that JJDC has no present intention of selling, granting 
participation in, or otherwise distributing the same. By executing this

                                       2.


<PAGE>
<PAGE>
Agreement, JJDC represents that it does not have any contract, undertaking,
agreement or arrangement with any person or entity to sell, transfer, or grant
participation, to such person or entity or to any third person or entity, with
respect to any of the Shares.

           (2) Restricted Securities. JJDC understands that the Shares have 
not been registered under the Act, on the ground that the sale provided for 
in this Agreement is exempt from the registration requirements of the Act, 
and that the Company's reliance on such exemption is predicated on Transferor's
and JJDC's representations set forth herein.

           JJDC understands that if the Company does not register with the 
Securities and Exchange Commission pursuant to sections 12 or 15 of the 
Securities Exchange Act of 1934 or if a registration statement covering the 
Shares (or a filing pursuant to the exemption from registration under 
Regulation A of the Act) under the Act is not in effect when he or she 
desires to sell the Shares, JJDC may be required to hold the Shares for an 
indeterminate period. JJDC also acknowledges that it understands that any 
sale of the Securities that might be made by JJDC in reliance upon Rule 144 
under the Act may be made only in limited amounts in accordance with the 
terms and conditions of that rule and that JJDC may not be able to sell the 
Shares at the time or in the amount JJDC so desires. JJDC is familiar with 
Rule 144 and understands that the Shares constitute "restricted securities" 
within the meaning of that Rule.

           (3) Investment Experience. In connection with the investment 
representations made herein JJDC represents that it is able to fend for itself 
in the transactions contemplated by this Agreement, has such knowledge and 
experience in financial and business matters as to be capable of evaluating 
the merits and risks of his or her investment, has the ability to bear the 
economic risks of its investment and has been furnished with and has had 
access to such information as JJDC has requested and deems appropriate to its 
investment decision.

           (4) Limitations on Disposition. JJDC agrees that in no event will it
make a disposition of any of the Shares, unless and until (a) JJDC shall have 
notified the Company of the proposed disposition and shall have furnished the 
Company with a statement of the circumstances surrounding the proposed 
disposition, and (b) JJDC shall have furnished the Company with an opinion 
of counsel reasonably satisfactory to the Company to the effect that (i) such 
disposition will not require registration of such Shares under the Act, or 
(ii) that appropriate action necessary for compliance with the Act has been 
taken, or (c) the Company shall have waived, expressly and in writing, its 
rights under clauses (a) and (b) of this subparagraph. In addition, prior to 
any disposition of any of the Shares, the Company may require the transferee 
or assignee to provide in writing investment representations and its agreement 
to the market stand-off provisions hereof in a form acceptable to the Company.
The restrictions on disposition imposed by this Section 3(f)(4) shall cease 
terminate as to the Shares when: (i) such securities shall have been 
effectively registered under the Act and sold by the holder thereof in 
accordance with such registration, or (ii) an opinion of

                                       3.


<PAGE>
<PAGE>
the kind described in the second preceding sentence states that all future 
transfers of such securities by the holder thereof would be exempt from 
registration under the 1933 Act.

           The Company shall not be required (i) to transfer on its books 
any Shares of the Company which shall have been sold or transferred in 
violation of any of the provisions set forth in this Agreement, or (ii) to 
treat as owner of such shares or to accord the right to vote as such owner 
or to pay dividends to any transferee to whom such shares shall have been 
so transferred. Transferor shall, during the term of this Agreement, exercise
all rights and privileges of a shareholder of the Company with respect to the 
Shares after the issuance, and prior to the repurchase, thereof.

        g. Legends. All certificates representing any Shares of the Company 
subject to the provisions of this Agreement shall have endorsed thereon the 
following legends (except that such certificates shall not be required to 
bear such legend after a transfer thereof if the transfer was made in 
compliance with Rule 144 or pursuant to a registration statement or, if the 
opinion of counsel referred to above is issued and provides that such legend 
is not required in order to establish compliance with any provisions of the 
1933 Act):

           (1) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT 
TO THE TERMS AND CONDITIONS OF A CERTAIN INVENTORY TRANSFER/STOCK PURCHASE 
AGREEMENT WHICH INCLUDES A MARKET STAND-OFF AGREEMENT ON THE SALE OF THE 
SECURITIES. COPIES OF THE AGREEMENTS MAY BE OBTAINED UPON WRITTEN REQUEST 
TO THE SECRETARY OF THE CORPORATION."

           (2) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
REGISTERED UNDER THE SECURITIES ACT OF 1933. THESE SECURITIES HAVE BEEN 
ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION OR RESALE, AND 
MAY NOT BE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH 
SHARES UNDER THE SECURITIES ACT OF 1933, OR PURSUANT TO RULE 144 UNDER THE 
ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION 
IS NOT REQUIRED UNDER SUCH ACT."

           (3) Any legend required to be placed thereon by applicable state 
laws.

        4. Representations and Warranties of the Company. The Company hereby 
represents and warrants to Transferor and JJDC that:

                                       4.

           c. Valid Issuance of Series B Preferred and Common Stock. The 
Shares, when issued, sold and delivered in accordance with the terms of this 
Agreement for the consideration expressed herein, will be duly and validly 
issued and outstanding, fully paid, and nonassessable, free of any liens, 
encumbrances, preemptive rights or rights of first refusal and will be issued

        d. Capitalization. The entire authorized capital stock of the Company 
consists of (a) 5,000,000 shares of Common Stock, of which 200,000 shares are 
issued and outstanding and (b) 1,000,000 shares of preferred stock (the

shares have been designated Series B Preferred Stock (the terms of which have

compliance with all applicable federal and state securities laws. No shares of
Common stock or Preferred Stock are held in the Company's treasury. There are no

shares of Common Stock or Preferred Stock. The Company has reserved 234,800
shares of Common Stock under its stock option plans. There are no preemptive
rights with respect to the issuance or sale by the Company of any of its
securities. The capitalization of the Company, giving effect to the transactions
contemplated hereby including those under Section 5.5 hereof, is as set forth in
Schedule I attached hereto.

        e. Securities Laws. Assuming that J&J's representations and warranties
contained in Section 3 of this Agreement are true and correct, the offer, 
issuance and sale of the Shares will be exempt from the registration and 
prospectus delivery requirements of the Securities Act of 1933, as amended 
(the "1993 Act"), and have been registered or qualified (or are exempt from 
registration and qualification) under the registration, permit or qualification
requirements of all applicable state securities laws. The Company agrees that 
neither the Company nor anyone acting on its behalf will offer any of the 
Shares or any similar securities for issuance or sale to, or solicit any 
offer to acquire any of the same from, anyone so as to make the issuance and 
sale of the Shares subject to the registration requirements of Section 5 of 
the 1933 Act.

     5. Conditions to Transferor's Obligations. The obligations of Transferor 
and JJDC under this Agreement are subject to the fulfillment on or before the 
date hereof of each of the following conditions:

        5.1 Performance. The Company shall have performed and complied with 
all agreements, obligations, and conditions contained in this Agreement that 
are required to be performed or complied with by it on or before the date 
hereof.

        5.2 Execution and Delivery of Co-Sale Agreement and Registration 
Rights Agreement. The Company shall have executed and delivered the 
Registration Rights Agreement and the Co-Sale Agreement.

        5.3 Opinion of Special Counsel to the Company Counsel. JJDC shall have
received from Brobeck, Phleger & Harrison LLP, counsel for Discovery 
laboratories, Inc. ("Discovery") and Special Counsel to the Company solely 
for the purpose of rendering an opinion pursuant to this Section 5.3, an 
opinion addressed to JJDC stating that:

            a. The Company is a corporation duly organized and validly 
existing under, and by virtue of, the laws of the State of Delaware and is 
in good standing under such laws. The Company has requisite corporate power

                                       6.


<PAGE>
<PAGE>
to own operate its properties and assets, and to carry on its business as
presently conducted.

            b. The Company has all requisite legal and corporate power to 
execute and deliver the Agreements, to issue the Shares under this Agreement 
and to carry out and perform it obligations under the terms of each of the 
Agreements.

            c. The authorized capital stock of the Company consists of 
2,000,000 shares of Common Stock, 200,000 shares of which are issued and 
outstanding, and 1,000,000 shares of Preferred Stock, of which 600,000 and 
2,200 shares have been designated Series A Preferred Stock and Series B 
Preferred Stock, respectively. The Shares when issued under this Agreement 
will be validly issued, fully paid and nonassessable and free of any liens, 
encumbrances and preemptive or similar rights contained in the Certificate of 
Incorporation of the Company, or, to such counsel's knowledge, in any agreement
to which the Company is a party, except as specifically provided in the 
Agreements; provided, however, that the Shares may be subject to restrictions
on transfer under state and/or federal securities laws as set forth in the 
Agreements. To such counsel's knowledge, except for rights described in the 
Agreements and the Certificate of Incorporation, there are no other options, 
warrants, conversion privileges or other rights presently outstanding to 
purchase or otherwise acquire any authorized but unissued shares of capital 
stock or other securities of the Company, or any other agreements to issue 
any such securities or rights, except as such counsel may set forth on a 
schedule of exceptions to the opinion being rendered pursuant to this 
Section 5.3.

            d. All corporate action on the part of the Company, its directors 
and shareholders necessary for the authorization, execution and delivery of 
the Agreements by the Company, the authorization, sale, issuance and 
delivery of the Shares and the performance of the Company's obligations under
the Agreements have been taken. The Agreements have been duly and validly 
executed and delivered by the Company and constitute valid and binding 
obligations of the Company, enforceable against the Company in accordance 
with its terms.

            e. No consent, approval or authorization of or designation, 
declaration or filing with any governmental authority on the part of the 
Company is required in connection with the valid execution and delivery of 
the Agreements or the offer, sale or issuance of the Shares or the consummation
of any other transaction contemplated by the Agreements, other than the filing 
of the Certificate of Designation for the Series A Preferred Stock and the 
Certificate of Designation for the Series B Preferred Stock with the 
Secretary of State for the State of Delaware.

            f. Subject to the accuracy of the Transferor's representations in
Section 3 of this Agreement and of the representations made by the other
purchasers of the Company's securities in connection with the formation and
financing of the Company, we are of the opinion that the offer, sale and
issuance of the Shares in conformity with the terms of the Agreement constitutes

                                       7.

<PAGE>
<PAGE>
a transaction exempt from the registration requirements of Section 5 of the

Company shall have delivered to Transferor a certificate dated the date of

and 5.5 hereof have been fulfilled.

     6. "Market Stand-Off" Agreement. Transferor hereby agrees that, during
the period specified by the Company and the underwriter or underwriters of
common stock (or other securities) of the Company, following the effective
date of a registration statement of the Company filed under the Securities
Act of 1933, as amended (the "Act"), Transferor shall not to the extent
requested by the Company and such underwriter, but in any case for a period
not to exceed 180 days, directly or indirectly, sell, offer or contract
to sell (including, without limitation, any short sale), grant any option
to purchase or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound) any securities of the Company at any time during
such period except common stock included in such registration, provided,
however, that (a) such agreement shall be applicable only to the first such
registration statement of the Company which covers common stock (or other
securities) to be sold on its behalf to the public in an underwritten offering
and (b) all other shareholders of the Company holding securities of the
Company enter into similar agreements.

     In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to Shares held by JJDC until the end
of such 180-day period.

     7. Miscellaneous.

            Every provision of this Agreement is intended to be severable. If
any term or provision hereof is deemed unlawful or invalid in any jurisdiction

or provision in any other jurisdiction. To the extent that any such term or
provision is held to be unlawful or invalid, the parties agree to reform such
term or provision in such a way which will be enforceable in the jurisdiction to

agreements and understandings related to the central subject matter thereof.

laboratory  notebooks  and the like) with  regard to any  governmental  approval
process or if required by any governmental  approval  agency,  WARF will use its
best  efforts  to  obtain  such  raw  data  from  Sumitomo  and/or  Taisho  upon
Discovery's  written  request to WARF.  WARF  shall pay the  actual  cost of the
translation and verification of the translation of such data. Within thirty (30)
days after the receipt of a supported invoice regarding such payments, Discovery
will  reimburse  WARF for all such  payments,  provided that the  translation is
requested or approved by Discovery.  All  additional  data provided to Discovery
under this Section 2A(ii)(3) shall be considered Product Information hereunder.

          B. Sublicenses.

               (i)  Discovery  may  grant  written,  exclusive  or  nonexclusive
          sublicenses to third parties;  however, WARF shall not have any direct
          enforcement  obligations to any such sublicensees under Section 9. Any
          agreement  granting a sublicense  shall state that the  sublicense  is
          subject to the termination of this Agreement. Discovery shall have the
          same  responsibility  for the activities of any  sublicensee as if the
          activities were directly those of Discovery.

   
               (ii) In respect to  sublicenses  granted by Discovery  under this
          Section  2B,  Discovery  shall  pay to WARF  [***]. In addition if
          Discovery receives any fees, minimum royalties or other payments in
          consideration for any rights granted under a sublicense, and such
          payments are not based directly upon the amount or value of products
          sold by the sublicensee, (hereinafter defined as "Other Sublicensee
          Income") then Discovery shall pay to WARF [***] of such Other
          Sublicensee Income in the manner specified in Section 3F; provided,
          however, that other Sublicensee Income shall exclude the following,
          in relation to which no payments shall be due to WARF:

                    (a) payments received by Discovery solely for performance of
               research and development including, but not limited to, milestone
               payments  for   achievement   of   objectives   in  research  and
               development,  but only to the extent that such payments cover the
               actual cost of the research  and  development  work  conducted by
               Discovery  or cover the  license  fees due on the  completion  of
               certain development milestones by Discovery under Sections 3B and
               3C hereof;

                    (b) Investments made by a sublicensee in either Discovery or
               one of its  affiliates  to the extent that such  investments  are
               made at current  market value,  including but not limited to, any
               payments or other  consideration  representing the current market
               value of shares in Discovery or any of its affiliates;

                    (c)  Payments  made to  Discovery  solely to the extent that
               they cover the actual costs of  conducting  clinical  testing and
               other   activities  in  connection   with  obtaining   regulatory
               approvals for Products; or

                    (d) Reimbursed expenses of Discovery.

For  purposes  of  Subsection  (b)  above,  the  "current  market  value" of the
investment shall be determined as follows:  (i) it shall be determined as at the
earlier of (a) the date when the  investment is made or (b) the day prior to the
date when the investment is first publicly  disclosed on the Dow Jones News Wire
(the  "Determination  Date");  (ii) if there is no public market for Discovery's
securities that are being purchased by the sublicensee,  then the current market
value shall be determined by Discovery's  Board of Directors in good faith,  and
if  WARF  disputes  such  determination,  the  current  market  value  shall  be
determined  by an  independent  investment  banker whose fees shall be shared by
Discovery and WARF; (iii) if there is a public market for Discovery's securities
that are being purchased by the sublicensee, then the current market value shall
be  determined  using the  average of the  closing  bid and asked  prices of the
securities in the Over-The-Counter Market Summary or the closing price quoted on
any exchange on which the  securities are listed as published in The Wall Street
Journal  for  the  ten  (10)  trading  days  prior  to the  Determination  Date.
Notwithstanding  the  foregoing,  in the event  the  sublicensee  is  purchasing
Discovery's securities in connection with Discovery's initial public offering of
such securities, the current market value shall be determined using the offering
price of such securities to the public in Discovery's  initial public  offering.
Discovery shall not receive from sublicensees  anything of value in lieu of cash
payments in consideration  for any sublicense  under this Agreement  without the
express prior written permission of WARF.
    

          C. Option.

     WARF hereby grants Discovery an option to expand the Licensed  Territory to
include all countries of the world except Argentina,  Spain, Portugal, Korea and
Japan by paying the appropriate option fees on the schedule set forth in Section
3C of this Agreement.

          D. Standstill.

     During  the term of this  Agreement,  WARF will not grant a license  to any
third party to the Compound or the Product  Information for any other indication
in the Licensed  Territory,  excepting  WARF's  existing  license with  Penederm
Incorporated.

          E. Grant Forward.

               (i) To the extent permitted by applicable law, WARF hereby grants
          Discovery  a  nonexclusive  license  to make the  Compounds  under the
          claims of future  patent  applications,  and patents which mature from
          any  such  applications,  which  are  owned  by  WARF  if the  claimed
          inventions  are new and useful  processes  for making the Compounds or
          Products. Discovery's rights under such inventions shall be limited to
          the practice thereof within the Licensed Field and Licensed  Territory
          and shall be subject to the  intervening  rights of third parties that
          have  funded  the  research  under  which the  inventions  were  first
          conceived  and/or  made and to the rights of current  licensees.  WARF
          will promptly notify Discovery of any such invention by mailing a copy
          of the U.S.  patent  application,  without  claims,  directed  to such
          invention to:

                     Discovery Laboratories,  Inc.
                     Attn: Mr. Steve Kanzer
                     375 Park Avenue
                     New York, New York 10152

          Such notification  shall be given to Discovery promptly after WARF has
          filed the U.S. patent application.

               (ii)  Sixty  (60)  days  after   receipt  by  Discovery  of  such
          notification, and unless Discovery informs WARF in writing that it has
          elected  otherwise,  such new and useful  invention(s)  shall become a
          part of the Ancillary Patents hereunder. At any time more than two (2)
          years  after  receipt  by  Discovery  of such  notification,  WARF may
          inquire of Discovery as to whether  Discovery is in fact then actually
          using the added  invention(s) to make  Compounds.  If Discovery is not
          doing so, WARF may, at its sole discretion,  delete such  invention(s)
          from Ancillary Patents.

     Section 3. Consideration.

          A. Development.

     Discovery  agrees  to and  warrants  that:  it  has,  or will  obtain,  the
expertise  necessary to  independently  evaluate the  inventions of the Licensed
Patents;  it will establish and actively and diligently  pursue the  development
plan (see  Appendix H) to the end that the  inventions  of the Licensed  Patents
will be utilized to provide  Products for sale in the retail market;  and within
one month  following the end of each calendar  quarter  ending on March 31, June
30,  September 30 and December 31 and until the date of first commercial sale of
Products, it will supply WARF with a written Development Report. All development
activities and  strategies  and all aspects of Products  design and decisions to
market and the like are entirely at the  discretion of Discovery,  and Discovery
shall rely entirely on its own expertise with respect thereto.  WARF's review of
Discovery's  development  plan is solely to verify the existence of  Discovery's
commitment to development  activity and to assure  compliance  with  Discovery's
obligations  to  utilize  the  inventions  of  the  Licensed   Patents  for  the
marketplace,  as set forth above.  The development  plan set forth on Appendix H
represents  the  current  plans for the  development  work to be carried  out by
Discovery.  The parties  recognize and agree that it will be necessary from time
to  time  to  revise  the  development  plan  to  take  account  of  changes  in
circumstances  relating to the development work, and that the parties shall work
together in good faith to determine  mutually  acceptable  modifications  to the
development plan; provided,  however,  that such modifications shall only become
effective  once a written  revised  development  plan is prepared  and signed on
behalf of both parties

     development work is done in Europe)

     Upon Date of NDA Submission with the first                   $1,000,000
     European country's equivalent of the FDA

The above named  countries  shall be  considered  added to the  license  granted
hereunder by expansion of the Licensed  Territory  after payment of the $200,000
installment  due upon  exercise of the option to expand the Licensed  Territory.
All fees due under this  Section 3C are  payable  only once,  regardless  of the
number of Products, or submissions to the European equivalent of the FDA.

               (ii)  Discovery  agrees to pay an option  fee of  $500,000  on or
          before  January  1,  2002  to add  Australia,  New  Zealand,  Ireland,
          Finland,  Denmark,  Norway,  Sweden,  Greece and any and all remaining
          countries of the world to the  Licensed  Territory  except  Argentina,
          Spain, Portugal, Korea and Japan.

               (iii) In Argentina,  Spain,  Portugal and Korea,  Discovery shall
          have the right to prior review and  approval of any license  agreement
          to be  entered  into by WARF  under the  Licensed  Patents  or the Use
          Patents in the Licensed Field. Such approval shall not be unreasonably
          withheld. Such


                                  Page 5 of 26



<PAGE>
<PAGE>


license  agreements  shall provide that the licensees for any of the territories
of  Argentina,  Spain,  Portugal and Korea are (i)  prohibited  from directly or
indirectly  making  any sales or  marketing  products  containing  the  Compound
outside  of such  licensee's  territory  and  (ii)  required  to  mark  products
containing  the  Compound  as  not  for  resale   outside  of  such   licensee's
territories.  In the event that any of such  licensees  violates  the  foregoing
prohibition or  obligation,  WARF shall enforce its  contractual  rights against
such  licensee  to  the  greatest  extent   permitted   under   applicable  law.
Additionally,  WARF may only enter into a license with the following  parties in
the following countries:

     Argentina - Gador
     Spain and Portugal - FAES
     Korea - YuYu

If WARF and the above named companies are unable to reach agreement on a license
then  Discovery  shall  have the option to obtain a license  under the  Licensed
Patents and the Use Patents in the Licensed Field in Argentina,  Spain, Portugal
and Korea under the terms of a separate  agreement to be negotiated  between the
parties.  Such agreement  shall  incorporate  the required fees set forth in the
agreement between WARF and Sumitomo and Taisho, No. 93-0052, dated May 1, 1993.

          D. Royalty.

   
     In addition to the Section 3 license fee,  Discovery or its  sublicensee(s)
agree to pay WARF as "earned  royalties"  a royalty  equal to [***] of the
Net Selling Price of Products sold by Discovery in quarters where no Competive
Product is sold in a particular country and [***] of the Net Selling Price of
Products sold by Discovery in quarters when a Competing Product is sold
in a particular country during the period commencing on the date of first
commercial sale and ending on the Royalty Termination Date.
    

          E. Minimum Royalty.

   
     Discovery  further agrees to pay to WARF a minimum  royalty of $100,000 per
calendar year or part thereof during which this  Agreement is in effect starting
in  calendar  year  2002,  against  which any earned  royalty  paid for the same
calendar  year will be credited.  The minimum  royalty for a given year shall be
due at the time payments are due for the calendar quarter ending on December 31.
It is understood that the minimum royalties will apply on a calendar year basis,
and that sales of Products requiring the payment of earned royalties made during
a prior or subsequent  calendar year shall have no effect on the annual  minimum
royalty due WARF for any given calendar year.
    

          F. Accounting; Payments.

               (i) Amounts owing to WARF under  Sections 2B and 3D shall be paid
          on a quarterly basis, with such amounts due and received by WARF on or
          before the thirtieth  day  following  the end of the calendar  quarter
          ending on March 31, June 30, September 30 or December 31 in which such
          amounts were earned.  The balance of any amounts  which remain  unpaid
          for more than thirty (30) days after they are due to WARF shall accrue
          interest  until paid at the rate of the lesser of one percent (1%) per
          month or the maximum amount allowed under applicable law. However,  in
          no event shall this  interest  provision  be  construed  as a grant of
          permission for any payment delays.

               (ii) Except as  otherwise  directed,  all  amounts  owing to WARF
          under  this  Agreement  shall be paid in U.S.  dollars  to WARF at the
          address provided in Section 1 5(a). All royalties

          owing with respect to Selling  Prices stated in currencies  other than
          U.S.  dollars  shall be  converted  at the rate  shown in the  Federal
          Reserve  Noon  Valuation  - Value  of  Foreign  Currencies  on the day
          preceding the payment.

               (iii) A full  accounting  showing how any  amounts  owing to WARF
          under  Sections 2B and 3D have been  calculated  shall be submitted to
          WARF on the date of each such payment.  Such accounting  shall be on a
          per-country and product line,  model or  tradename  basis and shall be
          summarized on the form shown in Appendix E of this  Agreement.  In the
          event no payment is owed to WARF, a statement  setting forth that fact
          shall be supplied to WARF.

     Section 4. Certain Warranties of WARF.

          A. WARF warrants that except as otherwise provided under Section 13 of
     this Agreement with respect to U.S. Government  interests,  it is the owner
     of the Licensed  Patents,  Use Patents,  and Ancillary Patents or otherwise
     has the right to grant the licenses granted to Discovery in this Agreement.
     However, nothing in this Agreement shall be construed as:

               (i) a warranty or  representation  by WARF as to the  validity or
          scope of any of Licensed Patents, Use Patents or Ancillary Patents;

               (ii) a warranty or representation  that anything made, used, sold
          or otherwise  disposed of under the license  granted in this Agreement
          will or will not infringe patents of third parties;

               (iii)  an  obligation  to  bring or  prosecute  actions  or suits
          against  third  parties  for  infringement  of Licensed  Patents,  Use
          Patents or Ancillary Patents;

               (iv) an  obligation  to furnish  any  know-how  not  provided  in
          Licensed  Patents,  Use Patents or  Ancillary  Patents or any services
          other than those specified in this Agreement; or

               (v) a warranty or  representation  by WARF that it will not grant
          licenses to others to make,  use or sell products  not-covered  by the
          claims of the Licensed Patents, Use Patents or Ancillary Patents which
          may be similar  and/or compete with Products made or sold by Discovery
          or its sublicensee(s).

          B. WARF MAKES NO  REPRESENTATIONS,  EXTENDS NO WARRANTIES OF ANY KIND,
     EITHER EXPRESS OR IMPLIED, AND ASSUMES NO RESPONSIBILITIES  WHATSOEVER WITH
     RESPECT TO USE, SALE, OR OTHER DISPOSITION BY DISCOVERY, ITS SUBLICENSEE(S)
     OR THEIR VENDEES OR OTHER TRANSFEREES OF PRODUCTS  INCORPORATING OR MADE BY
     USE OF INVENTIONS LICENSED UNDER THIS AGREEMENT.

     Section 5. Recordkeeping.

          A.  Discovery  and its  sublicensee(s)  shall keep  books and  records
     sufficient to verify the accuracy and  completeness  of Discovery's and its
     sublicensee(s)'s accounting referred to above, including without limitation
     inventory,  purchase and invoice records  relating to the Products or their
     manufacture.  Such books and records  shall be  preserved  for a period not
     less than six years  after  they are  created  during and after the term of
     this Agreement.

<PAGE>


          B. Discovery and its sublicensee(s)  shall take all steps necessary so
     that WARF may within  thirty  days of its  request  review and copy all the
     books and  records at a single  U.S.  location  to verify the  accuracy  of
     Discovery's  and  its  sublicensee(s)'s  accounting.  Such  review  may  be
     performed by any employee of WARF as well as by any attorney or  registered
     CPA designated by WARF, upon reasonable  notice and during regular business
     hours.

          C. If a royalty  payment  deficiency is determined,  Discovery and its
     sublicensee(s)  shall pay the royalty deficiency  outstanding within thirty
     (30) days of receiving written notice thereof, plus interest on outstanding
     amounts as described in Section 3F(i).

          D. If a royalty  payment  deficiency  for a calendar year exceeds five
     percent (5%) of the  royalties  paid for that year,  then  Discovery or its
     sublicensee(s)   shall  be  responsible  for  paying  WARF's  out-of-pocket
     expenses incurred with respect to such review.

     Section 6. Term; Termination.

          A. The term of the license granted under this Agreement shall begin on
     the execution date and shall end on the Royalty  Termination  Date at which
     time Discovery shall have a paid-up license under this Agreement.

          B.  Discovery  may terminate  this  Agreement at any time by giving at
     least ninety days' written and  unambiguous  notice of such  termination to
     WARF.  Such a notice shall be accompanied by a statement of the reasons for
     termination.

          C. If  Discovery  at any time  defaults  in the timely  payment of any
     monies  due to WARF or the  timely  submission  to WARF of any  Development
     Report,  fails to  actively  pursue the  development  plan,  or commits any
     material  breach of any  other  material  covenant  herein  contained,  and
     Discovery  fails to remedy any such  breach or default  within  ninety days
     after written  notice thereof by WARF,  WARF may, at its option,  terminate
     this Agreement by giving notice of termination to Discovery.

          D. Upon the  termination  of this  Agreement,  Discovery  shall remain
     obligated to provide an accounting  for and to pay  royalties  earned up to
     the date of the termination and any minimum  royalties shall be prorated as
     of the date of  termination by the number of days elapsed in the applicable
     calendar year.

     Section 7. Assignability.

     This Agreement may not be transferred or assigned by Discovery  except with
the prior written  consent of WARF,  which shall not be  unreasonably  withheld;
provided  that  Discovery  may assign this  Agreement  (i) to the  purchaser  of
substantially  all of  Discovery's  stock,  assets or  business  pursuant to the
transaction  transferring  such  assets,  and (ii) to an  affiliate of Discovery
(meaning any entity which controls,  is controlled by or is under common control
with Discovery),  provided in each case that the assignee first agrees to assume
all of Discovery's obligations and liabilities under this Agreement.

     Section 8. Contest of Validity.

     In the event  Discovery  contests the  validity of any  Licensed  Patent or
Ancillary Patent, Discovery shall continue to pay royalties with respect to that
patent as if such  contest  were not  underway  until the patent is  adjudicated
invalid or unenforceable by a court of last resort.

     Section 9. Enforcement.

   
          A.  Licensed  Patents.  WARF intends to protect the  Licensed  Patents
     against  infringers  or otherwise act to eliminate  infringement,  when, in
     WARF's sole judgment, such action may be reasonably necessary,  proper, and
     justified.  In the event that Discovery  believes there is  infringement of
     any  Licensed   Patent  under  this  Agreement   which  is  to  Discovery's
     substantial  detriment,  Discovery  shall provide WARF with written  notice
     that such infringement is occurring including the following:
     (i) reasonable evidence  of the  infringement,  and  (ii) [***]; except in
     the event that the alleged infringer  identified by Discovery's
     infringement notice is either (a) any of the entities  identified in
     Section  3.C.(iii) hereof or (b) any other licensee of WARF's in relation
     to the Licensed Patents and/or the Use Patents, [***]. In the  event  that
     WARF  does  take  action  to abate  the infringement, [***]. If WARF does
     not take action to abate the infringement  of the Licensed  Patents within
     [***], Discovery  may either reduce the royalty  owed on sales of Products
     under Section 3D in the country where the  infringement  is occurring  from
     [***] to [***] until such  infringement  is abated or Discovery  may, with
     WARF's  written consent,  bring an action to enforce the  Licensed Patents.
     If  Discovery chooses to bring an action  against the infringer of the
     Licensed  Patents, [***].

          B. Use  Patents.  WARF  intends to  protect  the Use  Patents  against
     infringers or otherwise act to eliminate infringement, when, in WARF's sole
     judgment,  such action may be reasonably necessary,  proper, and justified.
     In the event  that  Discovery  believes  there is  infringement  of any Use
     Patent under this Agreement which is to Discovery's  substantial detriment,
     Discovery shall provide WARF with written notice that such  infringement is
     occurring   including  the  following: (i)  reasonable  evidence  of  the
     infringement,  and (ii) [***]; except in the event  that the  alleged
     infringer identified  by  Discovery's  infringement  notice is either  (a)
     any of the entities  identified in Section  3.C.(iii) hereof or (b) any
     other licensee of WARF's in relation to the Licensed  Patents  and/or the
     Use Patents, [***]. In the event that WARF does take action to abate the
     infringement, [***]. If WARF does not take action to abate the infringement
     of the  Licensed  Patents  within [***], Discovery may either reduce  the
     royalty  owed on sales of  Products  under  Section  3D in the country
     where the infringement is occurring from [***] to [***] until such
     infringement is abated or Discovery may bring an action to enforce the Use
     Patents.  If Discovery  chooses to bring an action  against the  infringer
     of the Use  Patents, [***].

     Section 10. Patent Marking.

     Discovery shall insure that it and its sublicensee(s) apply patent markings
that meet all  requirements  of U.S.  law, 35 U.S.C.  287,  with  respect to all
Products subject to this Agreement.

     Section 11. Product Liability; Conduct of Business.

          A. Discovery shall, at all times during the term of this Agreement and
     thereafter,  indemnify, defend and hold WARF, the inventors of the Licensed
     Patents and  Ancillary  Patents  harmless  against all claims and expenses,
     including legal expenses and reasonable  attorneys fees, arising out of the
     death of or  injury  to any  person  or  persons  or out of any  damage  to
     property  and  against any other  claim,  proceeding,  demand,  expense and
     liability of any kind whatsoever (other than patent infringement claims and
     claims based on WARF's fraudulent  conduct)  resulting from the production,
     manufacture,  sale, use, lease,  consumption or  advertisement of Products,
     the Compound,  or Ancillary  Compounds arising from any right or obligation
     of Discovery or any sublicensee hereunder.  Notwithstanding the above, WARF
     at all times  reserves the right to retain counsel of its own to defend its
     interests at its own expense.

          B. Discovery shall, at all times during the term of this Agreement and
     thereafter, indemnify, defend and hold Sumitomo and Taisho harmless against
     all claims and expenses,  including legal expenses and reasonable attorneys
     fees, arising out of the death of or injury to any person or persons or out
     of any damage to property and against any other claim, proceeding,  demand,
     expense  and   liability  of  any  kind   whatsoever   (other  than  patent
     infringement  claims and claims  based on Sumitomo  or Taisho's  fraudulent
     conduct)  resulting from the  production,  manufacture,  sale,  use, lease,
     consumption  or  advertisement  of  Products,  the  Compound,  or Ancillary
     Compounds  arising  from  any  right  or  obligation  of  Discovery  or any
     sublicensee   hereunder   and   relating   to  the   Product   Information.
     Notwithstanding the above,  Sumitomo and Taisho at all times shall have the
     right to retain counsel of their own to defend their  respective  interests
     at their own expense.

          C.  Discovery  warrants  that it now  maintains  and will  continue to
     maintain liability  insurance coverage  appropriate to the risk involved in
     marketing the products  subject to this  Agreement and that such  insurance
     coverage lists WARF and the inventors of the Licensed Patents and Ancillary
     Patents as additional insureds. Within thirty (30) days after WARF requests
     such  information  (which it may  request  not more  than  once per  year),
     Discovery  will  present  evidence  to WARF  that  the  coverage  is  being
     maintained with WARF and its inventors listed as additional insureds.

          D.  Discovery  warrants  that it now  maintains  and will  continue to
     maintain  liability  insurance  coverage  appropriate  to the  risk  of the
     Product  Information  involved in marketing  the  products  subject to this
     Agreement and that such  insurance  coverage  lists  Sumitomo and Taisho as
     additional  insureds.  Within  thirty  (30) days after WARF  requests  such
     information  (which it may request not more than once per year),  Discovery
     will present  evidence to WARF that the coverage is being  maintained  with
     Sumitomo and Taisho listed as additional insureds.

     Discovery and its sublicensee(s) shall not use WARF's name, the name of any
inventor of inventions governed by this Agreement, the name of the University of
Wisconsin, or the name of Sumitomo or Taisho in sales promotion, advertising, or
any other form of publicity  without the prior written approval of the entity or
person whose name is being used, except for or in connection with disclosures or
usages required by law (e.g., as a part of or in connection with relevant patent
applications,  filings to obtain governmental permits and approvals, disclosures
and  filings   required  by  stock  exchange  or  securities   laws,  rules  and
regulations).

     Section 13. United States Government Interests.

     It is understood that if the United States  Government  (through any of its
agencies or otherwise) has funded research,  during the course of or under which
any  of the  inventions  of the  Licensed  Patents  or  Ancillary  Patents  were
conceived or made, the United States Government is entitled,  as a right,  under
the provisions of 35 U.S.C. ss 200-212 and applicable regulations of Chapter 37
of  the  Code  of  Federal  Regulations,  to  a  nonexclusive,  nontransferable,
irrevocable, paid-up license to practice or have practiced the invention of such
Licensed  Patents or Ancillary  Patents for governmental  purposes.  Any license
granted to Discovery in this Agreement shall be subject to such right.

     Section 14. Miscellaneous.

     This Agreement  shall be construed in accordance  with the internal laws of
the State of Wisconsin.  If any  provisions of this  Agreement are or shall come
into  conflict  with  the  laws  or  regulations  of  any  jurisdiction  or  any
governmental  entity  having  jurisdiction  over the parties or this  Agreement,
those  provisions  shall be deemed  automatically  deleted,  if such deletion is
allowed  by  relevant  law,  and the  remaining  terms  and  conditions  of this
Agreement  shall  remain in full force and effect.  If such a deletion is not so
allowed or if such a deletion  leaves terms  thereby  made clearly  illogical or
inappropriate in effect, the parties agree to substitute new terms as similar in
effect  to the  present  terms of this  Agreement  as may be  allowed  under the
applicable laws and regulations.  The parties hereto are independent contractors
and not joint venturers or partners.

     Section 15. Notices.

     Any  notice  required  to be  given  pursuant  to the  provisions  of  this
Agreement  shall be in  writing  and shall be  deemed to have been  given at the
earlier of the time when  actually  received as a  consequence  of any effective
method of delivery, including but not limited to hand delivery,  transmission by
telecopier,  or delivery by a professional courier service or the time when sent
by certified or registered  mail addressed to the party for whom intended at the

4.1  For the rights and  privileges  granted  under this  SUBLICENSE  AGREEMENT,
     LICENSEE shall pay to LICENSOR earned  royalties equal to [***] of the NET
     SALES VALUE of LICENSED PRODUCTS sold by LICENSEE or its AFFILIATES.  With
     respect to sales by  SUBLICENSEES,  LICENSEE shall pay to LICENSOR earned

4.2  Earned royalty shall be paid pursuant to Article 4.1 hereof on all LICENSED
     PRODUCTS,  on  a  country-by-country  basis  for  [***]  years  from  first
     commercial sale of the first LICENSED PRODUCT in such country.  Thereafter,
     royalties  shall be paid in respect of a given  LICENSED  PRODUCT until the
     expiration  of the last to expire of the PATENT  RIGHTS  containing a VALID
     CLAIM covering the LICENSED PRODUCTS in such country.  Notwithstanding  the
     foregoing,  however,  with  respect to any country of the  European  Union,
     royalties  on NET SALES of  LICENSED  PRODUCTS  which are  payable  only by
     virtue of the LICENSED  KNOW-HOW shall be payable  commencing from the date
     of first  commercial sale of the first LICENSED PRODUCT in such country and
     ending  on the  earlier  of (i) the date on  which  the  LICENSED  KNOW-HOW
     becomes  published or generally known to the public through no fault on the
     part  of  LICENSOR,  its  AFFILIATES  or  SUBLICENSEES  or  (ii)  the [***]
     anniversary of the first  commercial sale of the first LICENSED  PRODUCT in
     any country of the European Union.

4.3  Any  LICENSED  PRODUCT  made  under  a  license  granted  pursuant  to this
     SUBLICENSE  AGREEMENT  prior  to  the  termination  or  expiration  of  the
     applicable  PATENT  RIGHTS  and  not  SOLD  prior  to  the  termination  or
     expiration  of such  PATENT  RIGHTS  shall be  subject  to the  payment  of
     royalties  hereunder  when SOLD,  even  though  such SALE occurs after the
     termination  or  expiration  of all  pertinent  licenses or rights  granted
     hereunder.

4.4  The earned  royalty for any particular  LICENSED  PRODUCT shall be due upon
     the first bona fide arm's length SALE thereof by LICENSEE,  an AFFILIATE or
     SUBLICENSEE, and any

[***] Confidential treatment requested.

                                      10

<PAGE>
<PAGE>

     subsequent SALE of such LICENSED PRODUCT by other than LICENSEE,  AFFILIATE
     or SUBLICENSEE  shall be royalty free. In the case of transfers or SALES of
     any  LICENSED   PRODUCT  between  LICENSEE  and  an  AFFILIATE  or  between
     AFFILIATES,  LICENSEE and  SUBLICENSEE,  one and only one royalty  shall be
     payable  thereon and such royalty shall become  payable upon the final SALE
     thereof to a third party other than LICENSEE, AFFILIATE or SUBLICENSEE.

4.5  For the purposes of reporting and making payments of earned royalties under
     this  SUBLICENSE  AGREEMENT,  the  manufacture,  SALE  or USE  of  LICENSED
     PRODUCTS by any  AFFILIATE  to which the license and rights shall have been
     extended shall be considered the manufacture,  SALE or USE of such LICENSED
     PRODUCTS by LICENSEE and any such AFFILIATE may make the pertinent  reports
     and royalty payments  specified in Article 4 hereof directly to LICENSOR on
     behalf of  LICENSEE;  otherwise,  such  reports and  payments on account of
     SALES  or USES of  LICENSED  PRODUCTS  by each  AFFILIATE  shall be made by
     LICENSEE;  and, in any event,  the SALES and USES of  LICENSED  PRODUCTS by
     each such AFFILIATE shall be separately shown in the reports to LICENSOR if
     such information is readily available to LICENSEE.

4.6  LICENSEE shall keep full, true and accurate books of account containing all
     particulars  which may be  necessary  for the purpose of showing the amount
     payable to LICENSOR by way of royalty as  aforesaid  or by way of any other
     provision  hereunder.  Said  books of account  shall be kept at  LICENSEE's
     principal  place of business.  Said books and the supporting  data shall be
     maintained  and kept  open at all  reasonable  times,  for  three (3) years
     following  the end of the  calendar  year to which they pertain (and access
     shall not be denied thereafter, if reasonably available), to the inspection
     of an  independent  accountant  retained  by  LICENSOR  for the  purpose of
     verifying LICENSEE's royalty statements, or LICENSEE's  compliance in other
     respects with  this  SUBLICENSE  AGREEMENT.  Names of  customers  and other
     confidential  information  shall  not be  disclosed  to  LICENSOR  by  such
     independent accountant. Such

                                      11

<PAGE>

     accountant shall be retained at LICENSOR's sole expense,  unless during any
     such  inspection a deficiency  in payments to LICENSOR of five percent (5%)
     or more is determined to exist in which event  LICENSEE shall within thirty
     (30)  days  reimburse  LICENSOR  for the full  expense  of  retaining  such
     accountant,  including but not limited to professional  and  administrative
     fees, travel and subsistence costs.

4.7  LICENSEE  within  ninety (90) days after the first day of  January,  April,
     July and October of each year shall deliver to LICENSOR a true and accurate
     report,  giving such particulars of the LICENSED PRODUCTS SOLD by LICENSEE,
     AFFILIATES  and royalty  received  from  SUBLICENSEES  during the preceding
     three (3) months ("Accounting  Period") under this SUBLICENSE  AGREEMENT as
     are pertinent to an accounting for royalty under this SUBLICENSE AGREEMENT.
     These shall  include at least the  following,  separately  stated as to the
     LICENSED PRODUCTS:

         (i)  the  quantity  of  LICENSED   PRODUCTS  invoiced  by  LICENSEE  or
         AFFILIATES during those three(3) months and the billings therefor;

         (ii) the allowable deductions therefrom;

         (iii) the calculation of royalties thereon.

     Simultaneously with the delivery of each such report, LICENSEE shall pay to
     LICENSOR  the  royalty  and any other  payments  due under this  SUBLICENSE
     AGREEMENT for the period  covered by such report.  If no royalties are due,
     it shall be so  reported.  Royalties  shall be paid to  LICENSOR  in United
     States  Dollars at LICENSOR's  office  specified for the purposes of giving
     notice in Article 14.2 hereof.

4.8  The remittance of royalties payable on sales outside the United States will
     be payable to LICENSOR in United States Dollar  equivalents at the official
     rate of exchange of the  currency of the country from which the  royalties
     are payable as quoted by The Wall Street Journal, New

                                     12

<PAGE>

     York Edition,  for the day upon which the transfer of funds for the royalty
     payment is made. If the transfer or the conversion into United States
     Dollar equivalents in any such instance is not lawful or possible, the
     payment of such part of the royalties as is necessary shall be made by the
     deposit thereof, in the currency of the country where the sales were made
     on which the royalty was based, to the credit and account of LICENSOR or
     its nominee in any commercial bank or trust company of its choice located
     in that country, prompt notice of which shall be given by LICENSEE to
     LICENSOR.

4.9  In the event that any taxes,  withholding  or otherwise,  are levied by any
     taxing  authority in  connection  with accrual or payment of any  royalties
     payable  to  LICENSOR  under this  SUBLICENSE  AGREEMENT,  LICENSEE  or its
     AFFILIATES  and/or  SUBLICENSEES  shall have the right to pay such taxes to
     the  local  tax  authorities  on behalf  of  LICENSOR  (or,  in the case of
     SUBLICENSEE  SALES, on behalf of LICENSEE),  and the payment to LICENSOR of
     the net amount due after  reduction  by the amount of such taxes,  together
     with  evidence of payment of such taxes,  shall  fully  satisfy  LICENSEE's
     royalty  obligations  under this SUBLICENSE  AGREEMENT.  LICENSEE agrees to
     make a good faith  effort to obtain a refund of any such taxes for LICENSOR
     if  LICENSOR  informs  LICENSEE  that it  believes  such  taxes  have  been
     improperly levied.

4.10 In the event that any  payment  required  under this  SUBLICENSE  AGREEMENT
     shall be overdue,  LICENSEE shall pay interest thereon at an annual rate of
     TWO percent  (2%) over the United  States  Clearing  Bank Base Lending Rate
     computed from the date when the payment  became due;  provided that if such
     rate shall be in excess of that allowed by applicable law, then the highest
     rate allowable shall apply.  Payment shall be deemed to have been made when
     received by LICENSOR.

     apply to any information that:

         (i) is or  hereafter  becomes  generally  available to the public other

     aware and which LICENSOR has a right to disclose to LICENSEE. LICENSOR will
     transfer its  pre-clinical,  clinical,  manufacturing  and  marketing  data
     relating to LICENSED PRODUCTS to LICENSEE, subject to the provisions of

6        DEVELOPMENT and COMMERCIALIZATION

6.1  LICENSEE shall, at its expense,  use reasonable  commercial  efforts (i) to
     conduct a research and development  program to obtain  regulatory  approval
     inside and outside the U.S. for use of the  LICENSED  PRODUCTS for at least
     one NEONATAL  INDICATION  and the ARDS  INDICATION  generally in accordance
     with the Development  Plan attached hereto as Appendix 3 (the  "Development
     Program");  and  (ii)  if,  in  LICENSEE's  opinion,  the  results  of  the
     Development  Program   demonstrate   acceptable  criteria  for  safety  and
     efficacy,  to file an NDA or PLA in at least  the  United  States  for such
     LICENSED  PRODUCTS  for a  NEONATAL  INDICATION  and the  ARDS  INDICATION.
     LICENSOR and LICENSEE shall review the Development  Plan from time to time.
     With the mutual  agreement of LICENSOR and LICENSEE,  the Development  Plan
     may be modified and the milestones set forth in Article 6.2(a) below may be
     extended.

6.2  (a)  Without  limiting  the  foregoing,   achievement  of  the  development
     milestones set forth below shall be an objective measure of LICENESEE's use
     of reasonable commercial efforts set forth in this Article 6;

         (i) the filing of an NDA or PLA for approval of a LICENSED PRODUCT
         for marketing in the U.S. [***] provided, however, that if LICENSEE
         abandons a NEONATAL INDICATION based on unsatisfactory safety or
         efficacy data for such indication. [***]

         (ii) commencement of marketing such LICENSED PRODUCT in the U.S. within
         [***] and

         (iii) no later than [***] commencement by LICENSEE of a program, either
         by itself or through a SUBLICENSEE, designed and adequately funded to
         obtain approval to market such LICENSED PRODUCT in the WESTERN EUROPEAN
         TERRITORY.
   
[***] Confidential treatment requested.
    
     The time periods specified in clauses (i) and (ii) above shall be subject
     to extension with LICENSOR's written consent, which shall not be withheld
     if LICENSEE reasonably requires additional time due to unforeseen
     regulatory or technical difficulties provided that LICENSEE is otherwise
     exercising the efforts recited in the first sentence of paragraph 6.1
     above. In such event, LICENSEE shall provide LICENSOR with a description of
     its reasons for requesting such extension, its modified schedule and its
     revised Development Plan for achieving such Milestones in accordance with
     the modified schedule.

     (b) Non-performance of this Article 6, including but not limited to, the
     failure to meet the deadlines set forth in Article 6.2(a) above, subject to
     extensions under Article 6.2(a) above if LICENSEE is using reasonable
     commercial efforts, shall be a breach or default under this SUBLICENSE
     AGREEMENT, entitling the LICENSOR, in addition to other remedies LICENSOR
     may have, to terminate this SUBLICENSE AGREEMENT under Article 7.3
     hereunder. In the event LICENSEE elects not to proceed with the Development
     Plan, or otherwise abandons one of (i) any of NEONATAL INDICATIONS or (ii)
     the ARDS INDICATION but is otherwise pursuing the other indication,
     LICENSOR may not terminate this SUBLICENSE AGREEMENT in its entirety, but
     LICENSOR shall have the right to partially terminate this SUBLICENSE
     AGREEMENT under Article 7.3 for the field of use comprising the abandoned
     indication only. Such termination provision shall not apply to an
     indication, however, in the event that the Phase II clinical trial for such
     indication, as set forth in the Development Plan, fails to demonstrate
     acceptable criteria for safety and efficacy. As used in this clause (c),
     the term "abandons", in respect of development

     of the LICENSED PRODUCTS, shall mean, prior to the first commercial sale of
     a LICENSED PRODUCT, the LICENSEE or its SUBLICENSEES have failed for a
     period of six (6) or more consecutive months to conduct any development,
     testing, regulatory, or manufacturing activity reasonably necessary to
     prepare and file an NDA or PLA for such LICENSED PRODUCT for such
     indication in the U.S. unless such failure was due to (i) reasons beyond
     its or their control (such as circumstances of the type observed in Article
     14.10 hereof) or (ii) the failure by LICENSOR to perform its obligation
     hereunder. LICENSEE shall give LICENSOR prompt written notice of its
     decision not to proceed with, or to abandon the development of LICENSED
     PRODUCTS for either indication.
    

6.3  Within  sixty (60) days  after the end of each  calendar  quarter  prior to
     first commercial sale of LICENSED PRODUCTS, LICENSEE shall submit a summary
     report to LICENSOR  reporting  the progress it, or its  SUBLICENSEES,  have
     made towards  commercialization in that quarter. This report will include a
     summary of the work done in the development of LICENSED PRODUCTS.

6.4  Promptly  following health regulatory  approval to market LICENSED PRODUCTS
     in such countries where approval is sought, LICENSEE agrees to use diligent
     efforts  to  promote  and  sell  LICENSED  PRODUCTS  at a  level  which  is
     consistent with those marketing  efforts normally used for similar products
     in the pharmaceutical industry.

7.       TERM; TERMINATION

7.1  Unless  terminated  sooner  pursuant  to the  terms  hereof,  this  LICENSE
     AGREEMENT  shall  become  effective  as of the  EFFECTIVE  DATE  and  shall

     obligation to pay royalties hereunder.

7.2  If (i) LICENSEE files a petition in bankruptcy or for the  appointment of a
     receiver  or  trustee,  (ii)  LICENSEE  proposes  a  written  agreement  of
     composition  or  extension  of its  debts or makes  an  assignment  for the
     benefit of its creditors, or (iii) an involuntary petition against LICENSEE
     is filed in any  insolvency  proceeding  and such petition is not dismissed
     within sixty (60) days after filing, LICENSOR may terminate this SUBLICENSE
     AGREEMENT.

7.3  Upon any material breach of or default under this  SUBLICENSE  AGREEMENT by
     LICENSEE,  or otherwise upon the abandonment of the entire Development Plan
     under  Article  6(b)(2)  hereof,  LICENSOR may  terminate  this  SUBLICENSE
     AGREEMENT,  partially or in its entirety,  by forty-five (45) days written
     notice to LICENSEE.  Said notice shall become  effective at the end of said
     period,  unless  during  said  period  LICENSEE  shall cure such  breach or
     default.

7.4  Notwithstanding  any  contrary  term  or  implication  of  this  SUBLICENSE
     AGREEMENT, LICENSEE may terminate this entire SUBLICENSE AGREEMENT on sixty
     (60) days  advance  written  notice to LICENSOR  for any reason,  whereupon
     LICENSEE  will not be  obligated  to make any further  payments to LICENSOR
     other than those payments accruing prior to such  termination.  In no event
     shall  LICENSEE be entitled  to a refund for any  payments  made or accrued
     prior to the date of termination.

7.5  Notwithstanding  any  other  provision  of this  LICENSE  AGREEMENT  to the
     contrary,  this LICENSE AGREEMENT may be terminated in countries other than
     the United States or the WESTERN  EUROPEAN  TERRITORY  without cause,  on a
     country-by-country basis, by LICENSEE at any time upon six (6) months prior
     written notice to LICENSOR. Upon such termination,  those rights granted to
     LICENSEE  hereunder  with respect to the  countries  for which this LICENSE
     AGREEMENT  is  terminated  shall  revert to  LICENSOR  for the  benefit  of
     LICENSOR.  Further,  in the event of any such  termination,  LICENSEE shall
     comply with the  provisions of  paragraph  7.7 hereof  with  respect to the
     LICENSED KNOW-HOW and

                                        19

     regulatory  approvals  and  filings  as  they  relate  to  such  terminated
     countries  and in  addition  shall  provide  LICENSOR  with  access  to any
     regulatory filings and approvals outside the terminated countries which are
     necessary  or useful  for  LICENSOR,  or its  designee,  to  obtain  health
     regulatory  approval  to  market  a  LICENSED  PRODUCT  in  the  terminated
     countries.   LICENSEE   agrees  to  provide   LICENSOR  with  any  required
     authorization letters to effectuate such access.

7.6  Upon termination of this SUBLICENSE AGREEMENT for any reason, other then by
     expiry of the PATENT RIGHTS,  all rights granted  hereunder shall revert to
     LICENSOR  for the benefit of  LICENSOR.  Upon  termination,  at  LICENSOR's
     written request,  LICENSEE agrees to assign any sublicense  rights which it
     may have  granted  under the PATENT  RIGHTS to  LICENSOR,  or to such legal
     entity specified by LICENSOR, and such sublicense shall survive termination
     of this SUBLICENSE  AGREEMENT,  provided that the SUBLICENSEE  continues to
     abide by the terms of the sublicense so assigned to LICENSOR.

7.7  Upon  termination  of this LICENSE  AGREEMENT  other than by  expiration in
     accordance with Article 7.1, LICENSEE undertakes:

         (i) to deliver to LICENSOR all copies of any  LICENSED  KNOW-HOW in its
         possession;

         (ii)  not to use the  LICENSED  KNOW-HOW  as  long as it has to be kept
         confidential under Article 5 hereof;

         (iii) to transfer to LICENSOR,  at  LICENSOR's  request,  copies of all
         KNOW-HOW  developed by LICENSEE  concerning  LICENSED PRODUCT,  and all
         health regulatory approvals and regulatory filings relating to LICENSED
         PRODUCTS;

         (iv) to the extent requested by LICENSOR, to transfer to LICENSOR or
         its designee responsibility for and control of ongoing LICENSED

         the date of such transfer;

         (v) to the extent requested by LICENSOR, to transfer to LICENSOR or its
         designee all inventory of LICENSED PRODUCTS and materials and equipment

         license under any patents or LICENSED  KNOW-HOW  owned or controlled by

     caused such infringement to terminate (for whatever cause) or initiated
     legal proceedings against the infringer within three (3) months following
     receipt or giving of notice pursuant to this Article 9.2, LICENSOR shall

10.  STATUS OF THE PATENT RIGHTS
   
10.1 Pursuant to the SCRIPPS AGREEMENT, SCRIPPS agreed, with the advice of
     LICENSOR, to diligently prepare, file and prosecute the patent applications
     filed within the PATENT RIGHTS and LICENSOR agreed to reimburse SCRIPPS for
     the reasonable expenses associated therewith. LICENSOR will continue to
     ensure the SCRIPPS will file, maintain and prosecute the patents and patent
     applications in the PATENT RIGHTS, and to continue to reimburse SCRIPPS for
     patent expenses, including expenses associated with any interference or
     opposition proceeding, under the SCRIPPS AGREEMENT as LICENSOR considers
     appropriate. Furthermore, to the extent not barred by the passage of time,
     LICENSOR will continue to file, maintain and prosecute the ORTHO patents
     and patent applications within the PATENT RIGHTS in the jurisdiction listed
     in Appendix 4.
    

10.2 LICENSOR  will  advise,  or ensure that  SCRIPPS  advises,  LICENSEE of the
     status of all patent  applications  and patents  within the PATENT  RIGHTS.
     LICENSOR  will provide or will ensure that SCRIPPS  provides  LICENSEE with
     copies of any patent  applications  or amendments or  continuations-in-part
     that it or SCRIPPS  proposes  to file with the U.S.  Patent  and  Trademark
     Office and shall give  LICENSEE the  opportunity,  for a period of at least
     five (5)  business  days  after  receipt,  to review  and  comment  on such
     applications.
   


                                            24

<PAGE>

    
   
10.3 Should LICENSOR elect not to continue paying the expenses for the
     maintenance or prosecution of any patent or patent application under the
     PATENT RIGHTS, it shall give LICENSEE ninety (90) days prior written notice
     thereof and LICENSEE may thereafter at its own expense, prepare, file,
     prosecute and maintain such patent or patent application in such countries
     worldwide as it deems appropriate and conduct any interferences,
     reexaminations, reissues or oppositions relating hereto. Any expenses which
     LICENSEE incurs under this Article 10.3 shall be credited against any
     royalties due under Article 3 and 4 of this SUBLICENSE AGREEMENT; provided
     that LICENSEE shall supply to LICENSOR reasonable documentation of such
     expenses.
    

10.4 LICENSOR  does not  represent or warrant that any patent  within the PATENT
     RIGHTS will be  obtained or that any such patent so obtained  will be valid
     and enforceable.  Specifically, LICENSEE acknowledges that the issuance and
     enforceability of any patent application or patent within the PATENT RIGHTS
     is subject to the outcome of any patent  office  proceeding,  including any
     interference  or  opposition  proceeding  involving  such  patent or patent
     application and that LICENSOR makes no representation  that any such patent
     application or patent will prevail in such  proceeding.  In the event such
     patent or patent  application is not issued or upheld in such  interference
     or  opposition  proceeding,  LICENSEE's  sole remedy is to  terminate  this
     SUBLICENSE AGREEMENT under Article 7.4 hereof.

10.5 The parties  agree to  cooperate in order to avoid loss of any rights which
     may  otherwise  be  available  to the  parties  under the U.S.  Drug  Price
     Competition  and Patent Term  Restoration  Act of 1984,  the  Supplementary
     Certificate  of Protection  of the Member States of the European  Community
     and other similar  measures in any other country in the Territory.  Without
     limiting the foregoing,  LICENSEE agrees to notify  LICENSOR  promptly upon
     receipt of an NDA or PLA  approval  to market any  LICENSED  PRODUCT in the
     United States and to timely supply LICENSOR with all information  necessary
     to file an application for

   
    

                                           25

<PAGE>
<PAGE>

     patent term extension  within the sixty (60) day period following U.S. NDA
     or PLA  APPROVAL.  The same shall apply with respect to the approval by the
     health  authorities  in a country of the European  Community or approval by
     the appropriate authorities in any other country in the Territory.

11   NON-USE OF NAMES

11.1 LICENSEE shall not use the name of any INVENTOR,  or any  institution  with
     which he has been or is connected, or of LICENSOR, or any adaptation of any
     of them, in any advertising, promotional or sales literature, without prior
     written consent obtained from LICENSOR in each case. LICENSEE shall require
     its  AFFILIATES  to comply with this  Article 11 to the same extent that it
     applies to LICENSEE.

11.2 LICENSOR  shall  not use the  name of  LICENSEE  or its  AFFILIATES  or any
     adaptation thereof, in any advertising,  promotional or sales literature or
     in any press  release  without  prior  written  consent of LICENSEE in each
     case.

         for  educational  and research  purposes in the SCRIPPS  PATENT RIGHTS,
         LICENSOR warrants that it has exclusive rights by agreement, assignment
         or license to SCRIPPS'  rights to the SCRIPPS  PATENT RIGHTS and to the
         ORTHO  PATENT  RIGHTS  and  that it has full  power  and  authority  to
         execute,  deliver  and  perform  this  Agreement  and  the  obligations
         hereunder;

         (ii) Other than the aforesaid  rights of the United States  Government,
         and SCRIPPS,  LICENSOR is not aware of any claims by any third  parties
         to an  ownership  interest  in the PATENT  RIGHTS  licensed to LICENSEE
         under this Agreement;

         (iii) The  SCRIPPS  AGREEMENT  is in full  force  and  effect as of the
         EFFECTIVE  DATE of this  SUBLICENSE  AGREEMENT  and  LICENSOR is not in
         material breach of the SCRIPPS  AGREEMENT nor has LICENSOR received any
         notice of  default  or  termination  from  SCRIPPS  under  the  SCRIPPS
         AGREEMENT,  nor is LICENSOR aware of any action or omission which, with
         the giving of notice or the passage of time, would constitute a default
         under the SCRIPPS AGREEMENT.

12.2 During  the term of this  Agreement,  LICENSOR  agrees to  comply  with the
     provisions of the SCRIPPS  AGREEMENT to prevent  termination  of LICENSOR's
     rights to the SCRIPPS  PATENT RIGHTS and to preserve the rights  granted to
     LICENSEE hereunder.

     this  SUBLICENSE  AGREEMENT  has been duly  approved and  authorized by all

     either party is a signatory.


12.4 Nothing in this SUBLICENSE AGREEMENT shall be construed as a representation
     or a warranty by LICENSOR as to the validity or scope of any patent  within
     the PATENT RIGHTS or that any process  practiced or anything made,  USED or
     SOLD under any license or immunity granted under this SUBLICENSE  AGREEMENT
     is or will be free from infringement of patents of third parties.

13.  INDEMNIFICATION

13.1 LICENSEE  agrees  to  indemnify  and  hold  harmless  INVENTORS,   SCRIPPS,
     LICENSOR,   its  AFFILIATES  and  their  respective  officers,   directors,
     employees  and agents  from and  against  any and all  claims,  damages and
     liabilities, including reasonable attorney's fees and expenses, asserted by
     third parties,  both government and private,  arising from LICENSEE's,  its
     AFFILIATES' and SUBLICENSEE's manufacture, USE or SALE of LICENSED PRODUCTS
     or the USE thereof by others including ultimate consumers. Prior to the
     first use of LICENSED PRODUCT in humans, LICENSEE hereby agrees to maintain
     in full force and effect general liability and product liability insurance
     with a commercial insurance carrier, which policy shall have individual and
     aggregate limits appropriate to the conduct of LICENSEE's business covering
     the sale and distribution of LICENSED PRODUCTS.  LICENSOR shall be named as

     insurance will not be canceled,  modified or subject to non-renewal without

     the Founder Stock Purchase  Agreement and Co-Sale Agreement entered into by

     construed  and  enforced  in  accordance  with the laws of the State of New
     Jersey,  United  States,  except as to any  issue  which  depends  upon the

     laws of the country of such patent.

14.4 Any dispute arising between the Parties under this LICENSE  AGREEMENT shall
     be referred to the President (or an officer designated by the President) of
     each Party who shall  promptly meet to discuss and resolve the dispute.  If

     discovery  by the  parties  not to exceed six (6)  months  from the date of
     filing of the notice of  arbitration  and the  arbitrators  shall  render a
     decision  within  thirty (30) days of the  completion  of the hearing.  The
     decision of the arbitrators  shall be final and without appeal,  and may be
     enforced in any court having jurisdiction over the Parties or their current
     assets. The fees of the arbitrators and the expense incident to the
     arbitration  proceedings  shall be borne equally by the Parties.  All other
     expenses,  such as legal fees,  shall be borne by the Party  incurring such
     expenses.

14.5 Nothing in this  SUBLICENSE  AGREEMENT  shall be construed so as to
     require the  commission  of any act  contrary  to law,  and  wherever
     there is any conflict  between any provision of this SUBLICENSE  AGREEMENT
     or concerning the legal right of the parties to contract and any statute,
     law,  ordinance or treaty, the latter shall prevail, but in such event the

                                     31

<PAGE>
<PAGE>

affected provisions of this SUBLICENSE  AGREEMENT shall be curtailed and limited

requirements.


14.6 LICENSEE  shall take all  reasonable  and necessary  steps to register this
     SUBLICENSE  AGREEMENT  in any  country  where  such is  required  to permit
     the transfer  of funds  and/or  payment of  royalties  to LICENSOR
     hereunder or is otherwise  required by the  government  or law of such
     country to  effectuate or carry out this SUBLICENSE AGREEMENT.
     Notwithstanding anything contained herein, but subject to Article  14(e)
     hereof,  LICENSEE  shall not be relieved of any of its obligations under
     this SUBLICENSE  AGREEMENT by any failure to register this SUBLICENSE
     AGREEMENT in any country,  and,  specifically, LICENSEE shall not be
     relieved of its  obligation  to make any payment  due to LICENSOR hereunder
     at LICENSOR's  address  specified  in Article  14.2  hereof,  where such
     payment is blocked due to any failure to register this SUBLICENSE
     AGREEMENT.

14.7 It shall be the full and sole responsibility of LICENSEE and its AFFILIATES
     to use  appropriate  care in the practice of any process and the
     manufacture and USE of any product  pursuant to any license or immunity
     granted hereunder  and LICENSOR shall have no right to control the manner
     in which or the material with which or upon which any process  licensed
     hereunder is practiced  and LICENSOR makes no representation or warranty
     whatsoever with respect to any such process or product.

14.8 As used in this  SUBLICENSE  AGREEMENT,  singular  includes  the plural and
     plural includes the singular,  wherever so required by the context. The
     headings appearing at the beginning of the numbered  Articles hereof have
     been inserted for convenience only and do not constitute a part of this
     SUBLICENSE AGREEMENT.

14.10 Notwithstanding any other provisions of this SUBLICENSE AGREEMENT,
      neither of the parties  hereto shall be liable in damages or have the
      right to terminate this  SUBLICENSE  AGREEMENT for any delay or default in
      performing hereunder if such delay or default is caused by conditions
      beyond its control including,  but not limited to acts of God,
      governmental  restrictions,  wars, or insurrections, strikes,  floods,
      work stoppages and/or lack of materials; provided,  however, that the
      party  suffering  such delay or default shall notify the other party in
      writing of the reasons for the delay or  default.  If such  reasons for
      delay or default  continuously exist for six (6) months, this SUBLICENSE
      AGREEMENT may be terminated by either party.

     pursuant to this SUBLICENSE  AGREEMENT shall be subject to SCRIPPS' rights

they be  independent  sales  agencies or  regularly  employed by  Licensee,  the

purposes  of  calculating  royalties  due to  Licensor  under  Article 4 of this
Agreement.

and Trademark  Office or any foreign patent office or patent agent. In addition,
Licensee  agrees that any and all official or "ribbon"  copies of issued patents

                            ARTICLE 7 - TERMINATION
                            -----------------------

     7.1 If  Licensee  shall  become  bankrupt  or  insolvent,  or shall  file a
petition in  bankruptcy,  or if the business of Licensee  shall be placed in the
hands of a receiver,  assignee or trustee for the benefit of creditors,  whether
by  the  voluntary  act  of  Licensee  or  otherwise,   this   Agreement   shall
automatically terminate.

     7.2 Time is of the essence for all payments  due.  Should  Licensee fail in
its payment to Licensor of royalties or license fees due in accordance  with the
terms of this Agreement which are not the subject of a bona fide dispute between
Licensor  and  Licensee,  Licensor  shall  have the right to serve  notice  upon
Licensee,  by certified mail to the address  designated in Article 14 hereof, of
its intention to terminate this  Agreement  within sixty (60) days after receipt
of said notice of termination unless Licensee shall pay to Licensor,  within the
sixty (60) day period, all such royalties or license fees due and payable.  Upon
the expiration of the sixty (60) day period, if Licensee shall not have paid all
such  royalties  or license  fees due and payable,  the rights,  privileges  and
license granted hereunder shall thereupon immediately terminate.  Payments shall
not be delayed,  escrowed or otherwise withheld absent a court order prohibiting
such payments.

     7.3 Upon any  material  breach or default of this  Agreement  by  Licensee,
other than those  occurrences  set out in  Paragraphs  7.1 and 7.2  hereinabove,
which shall always take  precedence  in that order over any  material  breach or
default  referred to in this  Paragraph  7.3,  Licensor  shall have the right to
terminate  this  Agreement  and  the  rights,  privileges  and  license  granted
hereunder  by ninety  (90) days'  notice to Licensee  by  certified  mail to the
address designated in Article 14 hereof. Such termination shall become effective
unless  Licensee  shall  have  cured  any such  breach or  default  prior to the
expiration  of the  ninety  (90)  day  period  from  receipt  of the  notice  of
termination.

     7.4 Licensee  shall have the right to terminate  this Agreement at any time
on sixty  (60)  days'  notice  to  Licensor  by  certified  mail to the  address
designated in Article 14 hereof.

     7.5 Upon termination of this Agreement for any reason, nothing herein shall
be construed to release either party from any  obligation  that matured prior to
the effective date of such termination.  Licensee and/or any Sublicensee thereof
may, however,  after the effective date of such  termination,  sell all Licensed
Products,  and complete  Licensed  Products in the process of manufacture at the
time of such termination, and sell the same, provided that Licensee shall pay to
Licensor the  royalties  thereon as required by Article 5 of this  Agreement and
shall  submit the reports  required by Article 5 hereof on the sales of Licensed
Products.

     7.6 Except as provided in Paragraph  7.5, upon  termination,  Licensee will
return  all  technology  and  rights  to  the  Licensed  Products  and  Licensed
Processes,  and both  Licensor and  Licensee  will  cooperate  in executing  the
necessary documentation.

5.  Escrowed Shares

    Shares comprising 7/40ths of the initial outstanding shares of KL4Co will
    be escrowed for the benefit of the Founding Personnel pending completion
    of KL4Co's second round of financing (the "Escrowed Shares"). The Escrowed
    Shares will be allocated between Discover and the Founding Personnel based
    upon the pre-money valuation realized in the second financing round in
    accordance with the following schedule:

                                 Percent of
          Pre-money              Incentive Shares
          Valuation              to Founding Personnel

          Less than $65MM        0%
          $65MM                  25%
          $75MM                  50%
          $85MM                  75%
          Over $95MM             100%

    A bridge financing in an amount not greater than $2,000,000 in which the
    proceeds are required to be repaid upon an initial public offering of KL4Co
    shall not be considered a second financing round for purposes of the
    Escrowed Shares. The Escrowed Shares will be allocated equally among the
    Founding Personnel based upon the ratable equity percentages of each.

6.  KL4Co shall establish a stock option plan for the benefit of its officers,
    directors, employees and consultants, provided, however, that it is intended
    that the Founding Personnel will not expect to receive option grants until
    at least 36 months following the formation of KL4Co, unless otherwise agreed
    to by the Board of Directors.

7.  Development Plan

    The development plan will proceed with the intention of conducting
    simultaneous phase II clinical trials in the ARDS and MAS indications,
    with the potential for additional trials in IRDS subject to discussion with
    the FDA.

    license to, including the right to sublicense, the KL4 Technology. Pursuant
    to the License Agreement, KL4Co shall pay license issue fees and royalties
    to J&J as follows (to be allocated between J&J and TSRI at their

       non-creditable, milestone payment of $250,000 upon the first NDA
       incorporating the KL4 Technology filed with the U.S. FDA;

    D. Second Milestone Payment. KL4Co shall pay J&J an additional
       non-refundable, non-creditable, milestone payment of $500,000 upon the
       first NDA incorporating KL4 Technology approved by the U.S. FDA; 
   
    E. Royalty on Sales. KL4Co shall pay royalties to J&J equal to [***]
       of net commercial sales by KL4Co, and with respect to sublicenses, [***].
    
    F. Due Diligence. The License Agreement will contain provisions requiring
       KL4Co to diligently develop the KL4 Technology for both the MAS and ARDS
       indications. In the event that KL4Co fails to proceed with the agreed
       upon development plan for either the MAS or ARDS indications, J&J shall
       have the right to terminate the License Agreement upon notice for the
       field of use comprising such indication. Such termination provision shall
       not apply to an indication, however, in the event that the proposed Phase
       II clinical trial for such indication fails to demonstrate acceptable
       scientific criteria for safety and efficacy.

Discovery Laboratories, Inc.
375 Park Avenue, Suite 1501
New York, N.Y. 10152

Dear Sirs:

            1. This is to confirm our understanding that Paramount Capital, Inc.
("Paramount") has been engaged as financial advisor of Discovery Laboratories,
Inc. (the "Company") for an initial period of twenty-four (24) months commencing
on the date hereof (as extended pursuant to Paragraph 10 hereto, or by mutual
agreement of the parties hereto, the "Term").

            2. The Company will pay Paramount a non-refundable retainer fee for
Paramount's services hereunder of $4,000 per month for twenty-four (24) months,
which such non-refundable retainer fee shall be payable in full in the amount of
$96,000 as of the date hereof.

            The Company also agrees to pay in cash all reasonable out-of-pocket
expenses incurred by Paramount in providing its services hereunder, including
fees and disbursements of Paramount's counsel, such expenses to be paid upon
submission of a bill or bills by Paramount from time to time. However, any
single expense over $500 for any month will require the prior written approval
of the Company. Fees and expenses of consultants or experts shall not be
included unless approved by the Company.


            3. Upon the Closing of each Investment (as defined below) during the
Term or during the twelve-month period following the expiration or earlier
termination of the Term, the Company shall pay to Paramount a fee in an amount
equal to 9% of the aggregate value of such Investment and shall issue to
Paramount warrants to purchase an amount of securities equal to 10% of the
securities sold as part of such Investment at an exercise price of 110% of the
price of such securities, exercisable until five years from the date of issuance
of such warrants. For the purposes of this Agreement, an Investment shall be any
purchase of securities of the Company which is made during the Term or during
the twelve-month period following the expiration of the Term by an investor
first introduced to the Company by or through Paramount during or prior to the
Term.

            4. (a) If the Company enters into an agreement with a party first
introduced to the Company by or through Paramount during or prior to the Term
pursuant to which the Company consummates a sale, merger, consolidation, tender
offer, business combination or similar transaction involving a majority of the
business assets or stock of the Company in which the Company is not the
surviving entity (a "Sale") during the Term, or during the twelve-month

<PAGE>
<PAGE>

period following the expiration of such Term, then the Company shall pay
Paramount a fee equal to 7% of the aggregate consideration paid to the Company
by the acquiror, such fee to be payable in cash simultaneously with the closing
of such Sale. With the exception of Acquiror Future Payments in which case such
fees are to be payable at such time, and only if, the Company receives such
Acquiror Future Payments.

            (b) If the Company enters into an agreement with a party first
introduced to the Company by or through Paramount during or prior to the Term
pursuant to which the Company consummates a transaction wherein the Company
acquires all or substantially all of the business assets or stock of another
entity in which the Company is the surviving entity (an "Acquisition") during
the Term, or during the twelve-month period following the expiration of such
Term, then the Company shall pay Paramount a fee equal to 7% of the aggregate
consideration paid by the Company to the entity acquired, such fee to be payable
in cash simultaneously with the closing of such Acquisition. With the exception
of Acquiror Future Payments in which case such fees are to be payable at such
time, and only if, the Company receives such Acquiror Future Payments.

            (c) For purposes of calculating Paramount's fee under this Paragraph
4, the aggregate consideration paid with respect to the business, assets or
stock of the Company shall be equal to the total of all cash, securities and/or
other assets paid for such business, assets or stock by the acquiror. Aggregate
consideration shall also include: (a) any commercial bank or similar
indebtedness of the Company that is repaid or for which the responsibility to
pay is assumed by the acquiror in connection with such transaction, (b) the
greater of the stated value or the liquidation value of preferred stock of the
Company that is assumed or acquired by the acquiror that is not converted into
common stock upon the consummation of such transaction, and (c) future payments
for which the acquiror is obligated either absolutely or upon the attainment of
milestone or financial results ("Acquiror Future Payments"). In the event a Sale
of the Company or an Acquisition by the Company is consummated through a
multiple-step transaction wherein the acquiror is not obligated either
absolutely or upon the attainment of milestones or financial results to make
future payments to further increase the acquiror's ownership in the Company (the
"Multiple-Step Payments"), the Company agrees to pay Paramount a fee on such
Multiple-Step Payments, and such fee shall be calculated pursuant to this
Paragraph 4. Such fee shall be payable when such Multiple-Step Payments are made
and shall be in addition to the fee paid to Paramount in the first step of such
transaction.

   
         5. If the Company enters into an agreement with a party first
introduced to the Company by or through Paramount during or prior to the Term
pursuant to which the Company consummates a Strategic Alliance(s) (as defined
below) during the Term, or during the twelve-month period following the
expiration of such Term, then the Company shall pay Paramount a fee equal to 6%
of the present value of the Aggregate Consideration (as defined below) to be
received by the Company, its shareholders or employees in each such transaction;
such fee to be payable in cash simultaneously with the closing of each such
transaction. With the exception of payments received by the Company after
closing of such transaction as in Paragraphs 5(c) and
    


                                        2
<PAGE>
<PAGE>

5(d) below, in which case such fees are to be payable at such time, and only if,
the Company receives such payments. For the purpose of calculating Paramount's
fee under this Paragraph 5, Aggregate Consideration shall include, but not be
limited to: (a) all payments made at closing for equity securities, equity
security rights or similar rights, (b) technology access fees or similar upfront
payments, (c) other future payments, including, without limitation, licensing
fees, royalties and deferred technology access fees, to be made to the Company
or its employees for which the Strategic Alliance partner(s) or other counter
party (each a "Partner") is obligated either absolutely, upon the attainment of
milestones or on a percentage or royalty basis, (d) funding provided, arranged
or introduced by the Partner (through reimbursement or otherwise) relative to
research and development, testing, clinical trials and related expenditures,
whether such work is performed, subcontracted or managed by the Company or the
Partner and (e) the repayment or assumption by the Partner of obligations of the
Company, including indebtness for money borrowed or amounts owed by the Company
to inventors or owners of technology. It is further understood that Aggregate
Consideration shall not be reduced by the amount of the fee due Paramount
hereunder. A "Strategic Alliance" may include, but is not limited to: (a) joint
venture, partnership, license or other contract for the research, development,
manufacturing, marketing, distribution, sale or other activity relating to the
Company's present and/or future products; (b) the purchase of, or commitment to
purchase from the Company, less than a majority of the business, assets or stock
of the Company by a Partner(s); (c) the sale of any of the Company's assets or
rights in respect to its products and/or technology; and (d) a commitment to
provide funding for all or part of the Company's research and development
activities, whether such work is performed or managed by the Company or Partner.

            For the purposes of calculating Paramount's fee, securities
constituting part of Aggregate Consideration that are traded on a national
securities exchange or the Nasdaq National Market System shall be valued at the
last closing price thereof prior to the date of the consummation or closing of
any such transaction. Such securities which are traded over-the-counter shall be
valued at the mean between the latest bid and asked prices prior to date.

            6. If Paramount introduces the Company to a potential product,
process or technology which is subsequently licensed or otherwise acquired by
the Company, the Company and Paramount shall negotiate in good-faith a fee for
such introduction provided in no event shall be such fee less than $120,000.

            7. In the event that the Company, its directors or management
initiate any discussions with a third party in furtherance of any Sale,
Acquisition, Investment or Strategic Alliance or receive any meaningful inquiry
or are aware of the interest if any third party concerning a Sale, Acquisition,
Investment or Strategic Alliance which is the subject of this Agreement, they
will promptly inform Paramount of the party and its interest and, subject to
Paragraph 8, if applicable, Paramount will undertake to provide its services
contemplated hereunder.

            8. Any financial advice rendered by Paramount pursuant to this
Agreement


                                        3
<PAGE>
<PAGE>

(and the existence of this Agreement) may not be disclosed publicly in any
manner without Paramount's prior written approval and will be treated by the
Company as confidential. The Company will provide Paramount with all financial
and other information requested by Paramount for the purposes of rendering its
services pursuant to this Agreement.

            9. All non-public information given to Paramount by the Company will
be treated by Paramount as confidential. In this regard, Paramount agrees to
enter into such confidentiality agreements which may be reasonably requested by
the Company. Paramount may rely, without independent verification, on the
accuracy and completeness of any information furnished to Paramount by the
Company.

            10. In the event that Paramount becomes involved in any capacity in
any action, proceeding, investigation or inquiry in connection with any matter
referred to in this Agreement or arising out of the matters contemplated by this
Agreement, the Company will reimburse Paramount for its legal and other expenses
(including the cost of any investigation and preparation) as they are incurred
by Paramount in connection therewith. The Company also agrees to indemnify each
of Paramount, the directors, officers, employees and agents thereof (the
"Indemnitees"), pay on demand and protect, defend, save and hold each Indemnitee
harmless from and against, on an after-tax basis, any and all liabilities,
damages, losses, settlements, claims, actions, suits, penalties, fines, costs or
expenses (including, without limitation, reasonable attorneys' fees)(any of the
foregoing, a "Claim") incurred by or asserted against any Indemnitee of whatever
kind or nature, arising from, in connection with or occurring as a result of
this Agreement or the matters contemplated by this Agreement, unless it shall be
finally judicially determined that such losses, claims, damages or liabilities
arise solely out of the gross negligence or willful misfeasance of Paramount in
performing the services which are the subject of this Agreement. The foregoing
agreement shall be in addition to any rights that any Indemnitees may have at
common law or otherwise.

            11. The Term of this Agreement shall be renewed for consecutive six
month periods upon the execution of a written agreement by both parties to
extend such Term and may be terminated by Paramount Capital, Inc. at any time
with or without notice; provided, however, regardless of any termination, the
right to reimbursement of all expenses incurred by Paramount contained in
Paragraph 2, the rights to compensation contained in Paragraphs 3, 4 and 5 and
to indemnity and reimbursement contained in Paragraph 10 shall survive.

            12. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York without regard to principles of conflicts
of law.

            13. This Agreement shall be binding upon Paramount and the Company
and the successors and assigns thereof. The Company shall not assign or sell all
or substantially all of the Company's business and/or assets without first
requiring in writing that such assignee or successor is bound by the provisions
of this Agreement.

 CERTIFICATES OF ANALYSIS AND MANUFACTURING COMPLIANCE

          4.1 CERTIFICATES OF ANALYSIS: COOK shall test, or cause to be tested,
 in accordance with the Specifications, each batch of the Drug Product
 manufactured pursuant to this Agreement before delivery to CLIENT. A
 certificate of analysis for each batch delivered shall set forth the items
 tested, specifications, and test results. COOK shall also indicate on the
 certificate of analysis that all batch production and control records have been
 reviewed and approved by the appropriate quality control unit. COOK shall send,
 or cause to be sent, such certificates to CLIENT prior to the shipment of the
 Drug Product. CLIENT shall test, or cause to be tested, for final release, each
 batch of the Drug Product as meeting the Specifications. As required by the FDA
 (see Paragraph 5.2 below), CLIENT shall assume full responsibility for final
 release of each lot of the Drug Product.

          4.2 MANUFACTURING COMPLIANCE: COOK shall advise CLIENT immediately if
 an authorized agent of any regulatory body visits COOK's manufacturing facility
 and makes an inquiry regarding COOK's method of manufacture of the Drug Product
 for CLIENT.

 WARRANTIES

          5.1 CONFORMITY WITH SPECIFICATIONS: COOK warrants that, at the time of
 manufacture, the Drug Product is prepared and tested in accordance with the
 Specifications, including cGMP. If the drug product does not meet
 specifications, and the reason being solely due to COOK's performance, then
 CLIENT will not be billed for the batch. Because of individual biological
 differences, no product is 100% effective under all circumstances. In addition,
 because COOK has no control of the conditions under which the Drug Product is
 used, the diagnosis of the patient before or after treatment with the Drug
 Product, the method of use or administration of the Drug Product, and handling
 of the Drug Product after it leaves COOK's possession, COOK does not warrant
 either a good effect, or against an ill effect, following the use of the Drug
 Product. The foregoing warranty is exclusive and in lieu of all other
 warranties either written, oral, or implied. THERE ARE NO WARRANTIES OF
 MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. No representative of COOK
 may change any of the foregoing warranties and CLIENT accepts the Drug Product
 subject to all terms hereof.

          5.2 COMPLIANCE: Client assumes responsibility for all contact
 with the FDA and other regulatory bodies, pertaining specifically to Drug
 Product.

 DRUG PRODUCT STOCK RECOVERY

          6.1 DRUG PRODUCT STOCK RECOVERY: In the event CLIENT reasonably
 determines that the Drug Product should be recovered because the Drug Product
 does not conform to Specifications, the parties shall take all appropriate
 corrective actions. In no event, however, shall COOK have responsibility for
 regulatory compliance in connection with any recovery, except to the extent and
 under the circumstances set forth in the Manual or as required by law. All
 costs and expenses incurred in connection with such recovery shall be the
 responsibility of CLIENT unless caused solely by the negligence of COOK. In no
 event shall COOK have any liability for consequential damages incurred by
 CLIENT which arise out of, or in connection with, any Drug Product recovery.

 FORCE MAJEURE; FAILURE TO SUPPLY

          7.1 FORCE MAJEURE EVENTS: failure of either party to perform under
 this agreement (except the obligation to make payments) shall not subject such
 party to any liability to the other if such failure is caused by acts such as,
 but not limited to, acts of God, fire, explosion, flood, drought, war, riot,
 sabotage, embargo, strikes or other labor trouble, compliance with any order or
 regulation of any government entity, or by any cause beyond the reasonable
 control of the parties, whether or not foreseeable, provided that written
 notice of such event is promptly given to the other party.

          7.2 FAILURE TO SUPPLY: If COOK fails to supply all or any material
 part of the Drug Product ordered by CLIENT, CLIENT may require COOK to
 supply the undelivered Drug Product or a lesser quantity at a future date
 agreed upon by CLIENT. The provisions of this Paragraph 7.2 shall be without
 prejudice to CLIENT's rights under paragraph 3.2 and remedies provided for
 thereunder.

 IMPROVEMENTS

          8.1 CHANGES BY CLIENT: If CLIENT requests a change to the Drug Product
 Specifications and COOK agrees that such change is feasible with regard to the
 manufacture of the Drug Product, such change shall be incorporated within the
 Specifications pursuant to a written amendment to this Agreement. The price of
 the Drug Product shall be adjusted for such change, and CLIENT shall pay COOK
 the costs associated with such change, including any development work, if
 necessary, based upon COOK's then-prevailing development rates. Such prices and
 costs shall be set forth in a written amendment to this Agreement. It is the
 responsibility of CLIENT to ensure that proper regulatory agencies approve the
 suggested changes.

          8.2 CHANGES BY COOK: COOK agrees that any changes developed by COOK
 which may be incorporated into the Drug Product shall be set forth in a written
 amendment to this Agreement prior to such incorporation and approved by CLIENT
 in writing. At the time of such incorporation, such changes shall become part
 of the Specifications. It is the responsibility of CLIENT to ensure that proper
 regulatory agencies approve the suggested changes.

 CONFIDENTIALITY

          9.1 This Agreement, by reference, incorporates the Confidentiality
 Agreement signed by CLIENT and COOK on January 3, 1996, and is made a part
 hereof as though fully set forth herein.

          9.2 Any invention made, conceived or reduced to practice by COOK in
 connection with the performance of the obligations under this Agreement, during
 the term of this Agreement or thereafter, whether derived from COOK or CLIENT,
 shall be considered confidential information and shall be the exclusive
 property of COOK; provided, however, that any invention made, conceived of, or
 reduced to practice during the Term of this Agreement, of (a) a pharmaceutical
 product with the same composition as the Drug Product, or (b) an improvement to
 the Drug Product, shall be the exclusive property of CLIENT. Each party, in its
 sole discretion, may file for patent protection of its invention as set forth
 above in its own name, and the other party, upon request by the owner, shall
 promptly sign and deliver any and all documents or information necessary for
 the securing of such invention in any country as determined by the owner.

          9.3 The parties agree that contents of this Agreement shall not be
 disclosed to any third party except (i) the controlling companies of the
 parties, (ii) the companies controlled by the parties, and (iii) governmental
 regulatory agencies, including, but not limited to, environmental protection
 authorities, without prior written consent of the other party.

 a period of ten (l0) years for future reference. The confidential information

 CLIENT shall supply to COOK, in a timely manner, all Bulk Drug Substance
 necessary to satisfy COOK's obligations under the Agreement. At some point,
 CLIENT wishes for COOK to supply the excipients, namely Palmitic Acid, DPPC,
 and POPG. When this occurs, a price will be negotiated and agreed to jointly
 by both parties.

 COOK will use standard operating procedures which define the sampling
 methodology and the analytical methods used to assure that the raw materials
 meet the Specifications. COOK and CLIENT agree that a vendor's certificate of
 analysis may be used in lieu of testing, where testing by COOK or CLIENT has
 validated the vendor. COOK and CLIENT will maintain supporting documentation.

 COOK will notify CLIENT in writing of any changes to the Specifications,
 sampling, or test methods of those raw materials listed in Attachment I that
 are included in the current USP/NF, and of any changes in the Approved Vendor
 List.

 For all raw materials listed in Attachment I which are not included in the
 current USP/NF, and for Bulk Drug Substance supplied by CLIENT or its agents,
 COOK shall obtain CLIENT's approval prior to instituting any changes to the
 Specifications, sampling, or test methods for that material.

 PACKAGING MATERIALS

 CLIENT shall be responsible for, and shall provide to COOK, all copy content,
 artwork and mechanicals for all printed materials associated with the Drug
 Product. This includes, but is not limited to, container labels, container
 cartons, package inserts, and promotional material. CLIENT shall be responsible
 for compliance with all Federal, State and Local laws and regulations
 concerning packaging and labeling materials, and for obtaining any necessary
 regulatory approvals of printed materials, artwork, and copy. Refer to Schedule
 I for details.

 CLIENT shall provide COOK with specifications for all packaging components
 including, without limitation, purchase description (general specifications for
 a class of packaging supplies; e.g., bottles, caps, cartons, etc.), acceptance
 criteria (including incoming inspection and sampling plans), and test methods
 used to determine conformance to specifications.

 CLIENT shall approve the specifications for product container closure
 components.

 COOK shall review and certify, by comparison to a master supplied by CLIENT,
 each receipt of printed components. Non-printed packaging components shall be
 tested by COOK according to COOK specifications.

 COOK shall notify CLIENT in writing of any changes to the specifications for 
 any components used in the Drug Product prior to use in manufacture.

 MASTER PRODUCTION RECORDS

 A Master Batch Record (MBR) is the formal set of instructions for the
 preparation of the Drug Product. A MBR shall be developed by COOK, using
 CLIENT's master formula and technical support provided by CLIENT.

 The MBR shall be maintained by the Document Control/Quality Assurance group
 within COOK. The MBR shall be written in the standard COOK format.

 The MBR shall be reviewed and approved by COOK and by CLIENT. Any change to an
 approved MBR will be reviewed and approved by COOK and by CLIENT prior to said
 change being implemented. Each batch of the Drug Product is produced by using a
 copy of the MBR. Each batch record is assigned a unique batch number.

 Any deviation from the specified manufacturing process must be documented in
 the batch record. COOK shall have a system to document the deviation, the
 investigation that was undertaken, and the conclusion drawn from that
 investigation. Appropriate departmental reviews and approvals by COOK shall be
 required prior to release of the Drug Product. The documentation associated
 with any deviation in the manufacturing process shall become part of the batch
 record.

 SAMPLING, TESTING AND RELEASE OF THE DRUG PRODUCT

 Each batch of the Drug Product manufactured and/or packaged by COOK shall be
 sampled in-process and at the completion of the manufacturing and packaging
 operations, as agreed to by COOK and CLIENT.

 All in-process and completed Drug Product testing shall be conducted by COOK or
 a third party designated by COOK using approved test methods, following receipt
 of written approval by CLIENT.

 All test methodologies shall be validated. For those procedures which appear in
 the current USP/NF, or other recognized standard reference, a statement
 indicating the reference shall suffice. For those test methods which are
 developed by COOK, documentation supporting the validation of the test method
 shall be documented. For test methods developed by CLIENT, CLIENT shall supply
 COOK with the supporting validation documentation.

 COOK shall provide CLIENT with a certificate of analysis indicating each test
 parameter, test result, and the corresponding acceptance criteria for each
 batch of the Drug Product manufactured or packaged, as well as a statement

during the term hereof, as and when Scripps makes the disclosure of each
application of Proprietary Property (whether Scripps Technology, Scripps Patent
Rights covering Scripps Technology, or Scripps' rights in Jointly Developed
Technology). The statement of general intention described in this subparagraph
is qualified in its entirety by the specific provisions of this Section 3.

         b. Subject to the terms of this Agreement, Scripps hereby grants to
Optionee an exclusive option to acquire an exclusive worldwide license to make,
have made, sell or use Licensed Products, with exclusive rights of sublicense,
in the Field. Each such license shall be to a specific application of Scripps
Technology, Scripps Patent Rights covering Scripps Technology, or Scripps'
rights in Jointly Developed Technology, as more particularly described in the
disclosure (Sections 3.2 or 3.3). Such option shall be for the period (Section
3.4) and exercised as (Section 3.5) more particularly described below.

         3.2 Disclosure of Scripps Technology. As soon as reasonably possible,
either upon conception or reduction to practice, as the case may be, of each and
every application of Scripps Technology, Scripps shall disclose the same in
writing to Optionee. Such disclosure shall contain sufficient detail to enable
Optionee to evaluate the advisability of exercising the option granted hereunder
with respect to such application. All such disclosures shall be maintained in
confidence by Optionee.

         3.3 Disclosure of Jointly Developed Technology. As soon as reasonably
feasible, either upon conception or reduction to practice, as the case may be,
of each and every application of Jointly Developed Technology, Optionee shall
disclose the same in writing to Scripps. Such disclosure shall contain
sufficient detail to enable Scripps to evaluate whether such technology is, in
fact, within the definition of Jointly Developed Technology. If Scripps, in the
exercise of its good faith discretion, acknowledges that all or some of such
technology as so described by Optionee falls within the definition of Jointly
Developed Technology, then Scripps shall deliver to Optionee a written notice
describing the Jointly Developed Technology and Scripps' intent to license the
same to Optionee if Optionee exercises its option.

         3.4 Option Period. Optionee shall have a period of one hundred eighty
(180) days from receipt of the disclosure from Scripps described in Section 3.2
above


                                       5

or from the notice from Scripps described in Section 3.3 within which to
exercise its option to obtain a license in the Field to a particular application
of Scripps Technology or to Scripps' rights to a particular application of
Jointly Developed Technology pursuant to Section 3.1.

         3.5 Exercise of Option. Optionee shall exercise its option to obtain a
license hereunder by delivering to Scripps a written notice within the option
period which specifies the particular application of Scripps Technology and
related Scripps Patent Rights or application of Jointly Developed Technology for
which the option is being exercised. Optionee and Scripps shall have a period of
ninety (90) days from the date of exercise of option by Optionee within which to
agree upon the royalty rate and commercial development obligations, all as is
more particularly set forth in the form of License Agreement attached hereto as
Exhibit C. The royalty rate shall be determined by the parties in accordance
with Exhibit D hereto. The specific application of Scripps Technology and
related Scripps Patent Rights, if any, or specific application of Jointly
Developed Technology which is the subject of such License Agreement will be as
set forth in the notice delivered by Scripps and described in Section 3.2 above
or Section 3.3, respectively. The "Field" in such License Agreement shall be no
broader than the Field defined herein.

         3.6 Reservation of Rights. Scripps reserves the right to use any
Scripps Technology or Jointly Developed Technology that may be subject to an
option pursuant to this Agreement or covered by a license granted hereunder
solely for Scripps' own educational and research purposes and the educational
and research purposes of any other nonprofit organization, provided that such
nonprofit organization is not using or disclosing the Scripps Technology or
Jointly Developed Technology for research or development purposes for a
for-profit entity, without Scripps or such other nonprofit organization being
obligated to pay Optionee any royalties or other compensation related thereto.

4.       WARRANTIES.

         4.1 Warranty of Title: No Other Warranties. Scripps hereby warrants and
represents that it has the full right and power to enter into this Agreement and
grant the option of Article 3 to Optionee.

         4.2 No Other Warranties. SCRIPPS MAKES NO WARRANTIES CONCERNING THE
RESEARCH PROGRAM OR ANY SCRIPPS TECHNOLOGY, SCRIPPS PATENT RIGHTS OR JOINTLY
DEVELOPED TECHNOLOGY WHICH MAY BE SUBJECT TO THIS AGREEMENT. WITHOUT LIMITING
THE FOREGOING, SCRIPPS DOES NOT REPRESENT OR WARRANT THAT IT WILL SUCCESSFULLY
COMPLETE THE RESEARCH PROGRAM OR THAT, IF COMPLETED, THE RESEARCH PROGRAM WILL
RESULT IN SCRIPPS TECHNOLOGY WHICH WILL BE SUBJECT TO AN OPTION HEREUNDER OR
WHICH OPTIONEE WILL DESIRE TO LICENSE. SCRIPPS MAKES NO EXPRESS OR IMPLIED
WARRANTY, INCLUDING



                                       6
<PAGE>
<PAGE>

BUT NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE, AS TO ANY LICENSED PRODUCT. SCRIPPS MAKES NO WARRANTY OR REPRESENTATION
AS TO THE VALIDITY OR SCOPE OF ANY SCRIPPS PATENT RIGHTS OR THAT ANY LICENSED
PRODUCT WILL BE FREE FROM ANY INFRINGEMENT OF PATENTS OF THIRD PARTIES, OR THAT
NO THIRD PARTIES ARE IN ANY WAY INFRINGING SCRIPPS PATENT RIGHTS.

5.       INTERESTS IN INTELLECTUAL PROPERTY.

         5.1 Title.

         a. Scripps shall retain such ownership and title to Scripps Technology
and Scripps Patent Rights as Scripps shall have, subject to the option of
Optionee set forth herein. Scripps shall, in the good faith exercise of its
discretion, undertake reasonable efforts to preserve and maintain its ownership
and title as Scripps deems appropriate. Ownership of and title to Jointly
Developed Technology shall be vested jointly in Scripps and Optionee, with each
owning an undivided one-half interest therein.

         b. In the event Optionee does not exercise its option hereunder to
obtain an exclusive license with respect to Scripps' rights in and to any
specific application of Jointly Developed Technology, Optionee hereby assigns to
Scripps all of Optionee's right, title and interest in and to such Jointly
Developed Technology, and Optionee shall have no further rights with respect
thereto, other than a right to receive from Scripps fifty percent (50%) of the
net royalty income received by Scripps with respect to such application, as and
when received. As used herein, "net royalty income" shall mean the gross
royalties and other license fees received under any such license agreement, less
all Scripps out-of-pocket expenses incurred in connection with the licensing of
such Jointly Developed Technology (including without limitation fees of
accountants, attorneys and other consultants engaged in connection with such
licensing).

         5.2 Governmental Interest. Optionee and Scripps acknowledge that
Scripps has received and expects to continue to receive funding from the United
States Government in support of Scripps' research activities. Optionee
acknowledges and agrees that its rights and obligations pursuant to this
Agreement with respect to Scripps Technology and Scripps Patent Rights, and to
Scripps' rights to Jointly Developed Technology, as applicable, shall be
subject to Scripps' obligations and the rights of the United States Government,
if any, which arise or result from Scripps' receipt of research support from the
United States Government.

6.       CONFIDENTIALITY AND PUBLICATION.



                                       7
<PAGE>
<PAGE>

         6.1 Confidential Information. The parties agree that during the term of
and any subsequent extension of this Agreement and for a period of five (5)
years after it terminates or for as long as any Confidential Information not
otherwise includable within Scripps Patent Rights is being utilized within a
Licensed Product, whichever is longer, a party receiving Confidential
Information of another party will not use or intentionally disclose such
Confidential Information to any third party without the prior written consent of
the disclosing party.

         6.2 Publications. Optionee acknowledges that it is the general policy
of Scripps to encourage publication of research results in technical or
scientific journals; and subject to Scripps meeting its disclosure obligations
under Section 3.2, Optionee agrees that Scripps shall have a right to publish in
accordance with its general policy. Prior to such publication, Scripps shall
submit to Optionee copies of proposed publications which contain subject matter
relating to Scripps Technology or Jointly Developed Technology and afford
Optionee a period of thirty (30) days to review the publication. Upon written
request by Optionee prior to the expiration of such thirty (30) day period and
provided that Optionee shall have exercised its option to one or more
applications included within the subject matter of such publication, Scripps
shall delay any such publication for up to sixty (60) days from the date of such
request to allow for the preparation and filing of a patent application.

         6.3 Publicity. Except as otherwise provided herein or required by law,
no party shall originate any publication, news release or other public
announcement, written or oral, whether in the public press, or stockholders'
reports, or otherwise, relating to this Agreement or to any license granted
hereunder, or to the performance thereunder, without the prior written approval
of the other parties, which approval shall not be unreasonably withheld.

7.       TERM AND TERMINATION.

         7.1 Term. Unless terminated sooner, the initial term of this Agreement
shall commence on the date set forth above and shall continue for a period of
two (2) years, and thereafter, this Agreement shall be renewable for additional
periods of one (1) years each upon mutual agreement of the parties.

         7.2 Termination by Mutual Agreement. This Agreement may be terminated
at any time upon the mutual written agreement of the parties. In the absence of
an agreement to the contrary, no such termination shall have the effect of
relieving Optionee of its monetary obligations to fund the Research Program
which shall have accrued up and to the date of such termination.

         7.3 Termination Upon Default. Any one or more of the following events
shall constitute an event of default hereunder: (i) the failure of a party to
pay any



                                       8
<PAGE>
<PAGE>

amounts when due hereunder and the expiration of thirty (30) days thereafter;
and (ii) the failure of a party to perform any obligation required of it to be
performed hereunder, and the failure to cure within sixty (60) days after
receipt of notice from the other party specifying in reasonable detail the
nature of such default. Upon the occurrence of an event of default, the
non-defaulting party may deliver to the defaulting party written notice of
intent to terminate, such termination to be effective upon the date set forth in
such notice. Such termination rights shall be in addition to and not in
substitution for any other remedies that may be available to the non-defaulting
party serving such notice against the defaulting party. Termination pursuant to
this Section 7.3 shall not relieve the defaulting party of liability and damages
to non-defaulting party for breach of this Agreement. Waiver by any party of a
single default or a succession of defaults shall not deprive such party of any
right to terminate this Agreement arising by reason of any subsequent default.

         7.4 Termination Upon Insolvency. This Agreement may be terminated as to
any party ("Insolvent Party") by another party giving written notice of
termination to the Insolvent Party upon the filing of bankruptcy or bankruptcy
of the Insolvent Party or the appointment of a receiver of any of the Insolvent
Party's assets, or the making by the Insolvent Party of any assignment for the
benefit of creditors, or the institution of any proceedings against the
Insolvent Party under any bankruptcy law. Termination shall be effective upon
the date specified in this notice.

7.5      Effect of Expiration or Termination.

         7.5.1 Termination Upon Default of Optionee. Upon the termination of
this Agreement by reason of a default by Optionee, neither party shall have any
further rights or obligations with respect to this Agreement, other than the
obligation of Optionee to make any and all final payments accrued prior to the
date of termination and the obligation of the parties to make all reports
required hereunder. Upon such termination of this Agreement, the parties shall
continue to abide by their non-disclosure obligations as described in Section
6.1 and each party hereto shall fulfill any other obligations incurred prior to
such termination. Any such termination of this Agreement shall not constitute
the termination of any license or any other agreements between the parties which
are then in effect except as expressly provided therein.

         7.5.2 Expiration or Termination upon Default of Scripps. Upon the
expiration of this Agreement at its regularly scheduled expiration date, or upon
a termination of this Agreement on account of a default by Scripps, then Scripps
shall make the disclosures required by Section 3.2 for Scripps Technology
conceived or reduced to practice up to the date of said expiration or
termination; and Optionee shall have the right to exercise its option with
respect to said Scripps Technology in accordance with the schedule and
procedures specified in Sections 3.4 and 3.5 above. Additionally, each party
shall perform all other obligations up to the date of said expiration or
termination; and the parties shall continue

                                       9
<PAGE>
<PAGE>


to abide by their non-disclosure obligations described in Section 6.1; and any
previously existing license agreements or other agreements between the parties
shall continue in effect.

8.       ASSIGNMENT: SUCCESSORS.

         8.1 Assignment. This Agreement may not be assigned by either party
without the prior written consent of the other party except to a successor in
interest to all or substantially all of the business assets of assigning party,
whether by way of a merger, consolidation, sale of all or substantially all of
the assigning party's assets, change of control or similar transaction.

         8.2 Binding Upon Successors and Assigns. Subject to the limitations on
assignment set forth herein, this Agreement shall be binding upon and inure to
the benefit of any successors in interest and assigns of Scripps and Optionee.
Any such successor to or assignee of a party's interest shall expressly assume
in writing the performance of all the terms and conditions of this Agreement to
be performed by such party.

9.       GENERAL PROVISIONS.

         9.1 Independent Contractors. The relationship between Scripps and
Optionee is that of independent contractors. Scripps and Optionee are not joint
venturers, partners, principal and agent, master and servant, employer or
employee, and have no other relationship other than independent contracting
parties. Scripps and Optionee shall have no power to bind or obligate each
other in any manner, other than as is expressly set forth in this
Agreement.

         9.2 Arbitration. Any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by binding
arbitration in accordance with the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"), and the procedures set forth below. In the
event of any inconsistency between the Rules of AAA and the procedures set forth
below, the procedures set forth below shall control. Judgment upon the award
rendered by the arbitrators may be enforced in any court having jurisdiction
thereof.

         9.2.1 Location. The location of the arbitration shall be in the City of
Philadelphia.

         9.2.2 Selection Arbitrators. The arbitration shall be conducted by a
panel of three neutral arbitrators who are independent and disinterested with
respect to the parties, this Agreement, and the outcome of the arbitration. Each
party shall appoint one neutral arbitrator, and these two arbitrators so
selected by the parties shall then select the third arbitrator. If one party 
has given written notice to the other party as to the



                                       10
<PAGE>
<PAGE>

identity of the arbitrator appointed by the party, and the party thereafter
makes a written demand on the other party to appoint its designated arbitrator
within the next ten days, and the other party fails to appoint its designated
arbitrator within ten days after receiving said written demand, then the
arbitrator who has already been designated shall appoint the other two
arbitrators.

         9.2.3 Discovery. Unless the parties mutually agree in writing to some
additional and specific pre-hearing discovery, the only pre-hearing discovery
shall be (a) reasonably limited production of relevant and non-privileged
documents, and (b) the identification of witnesses to be called at the hearing,
which identification shall give the witness's name, general qualifications and
position, and a brief statement as to the general scope of the testimony to be
given by the witness. The arbitrators shall decide any disputes and shall
control the process concerning these pre-hearing discovery matters. Pursuant to
the Rules of AAA, the parties may subpoena witnesses and documents for
presentation at the hearing.

         9.2.4 Case Management. Prompt resolution of any dispute is important to
both parties; and the parties agree that the arbitration of any dispute shall be
conducted expeditiously. The arbitrators are instructed and directed to assume
case management initiative and control over the arbitration process (including
scheduling of events, pre-hearing discovery and activities, and the conduct of
the hearing), in order to complete the arbitration as expeditiously as is
reasonably practical for obtaining a just resolution of the dispute.

         9.2.5 Remedies. The arbitrators may grant any legal or equitable
remedy or relief that the arbitrators deem just and equitable, to the same
extent that remedies or relief could be granted by a state or federal court,
provided however, that no punitive damages may be awarded. No court action may
be maintained seeking punitive damages. The decision of any two of the three
arbitrators appointed shall be binding upon the parties.

         9.2.6 Expenses. The expenses of the arbitration, including the
arbitrators' fees, expert witness fees, and attorney's fees, may be awarded to
the prevailing party, in the discretion of the arbitrators, or may be
apportioned between the parties in any manner deemed appropriate by the
arbitrators. Unless and until the arbitrators decide that one party is to pay
for all (or a share) of such expenses, both parties shall share equally in the
payment of the arbitrators' fees as and when billed by the arbitrators.

         9.2.7 Confidentiality. Except as set forth below, the parties shall
keep confidential the fact of the arbitration, the dispute being arbitrated, and
the decision of the arbitrators. Notwithstanding the foregoing, the parties may
disclose information about the arbitration to persons who have a need to know,
such as directors, trustees, management



                                       11
<PAGE>
<PAGE>

employees, witnesses, experts, investors, attorneys, lenders, insurers, and
others who may be directly affected. Additionally, if a party has stock which is
publicly traded, the party may make such disclosures as are required by
applicable securities laws. Further, if a party is expressly asked by a third
party about the dispute or the arbitration, the party may disclose and
acknowledge in general and limited terms that there is a dispute with the other
party which is being (or has been) arbitrated. Once the arbitration award has
become final, if the arbitration award is not promptly satisfied, then these
confidentiality provisions shall no longer be applicable.

         9.3 Entire Agreement; Modification. This Agreement sets forth the
entire agreement and understanding between the parties as to the subject matter
hereof. There shall be no amendments or modifications to this Agreement, except
by a written document which is signed by both parties.

         9.4 California Law. This Agreement shall be construed and enforced in
accordance with the laws of the State of California.

         9.5 Headings. The headings for each article and section in this
Agreement have been inserted for the convenience of reference only and are not
intended to limit or expand on the meaning of the language contained in the
particular article or section.

         9.6 Severability. Should any one or more of the provisions of this
Agreement be held invalid or unenforceable by a court of competent jurisdiction,
it shall be considered severed from this Agreement and shall not serve to
invalidate the remaining provisions thereof. The parties shall make a good faith
effort to replace any invalid or unenforceable provision with a valid and
enforceable one such that the objectives contemplated by them when entering this
Agreement may be realized. 

         9.7 No Waiver. Any delay in enforcing a party's rights under this 
Agreement or any waiver as to a particular default or other matter shall not 
constitute a waiver of such party's rights to the future enforcement of its 
rights under this Agreement, excepting only as to an express written and 
signed waiver as to a particular matter for a particular period of time.

         9.8 Attorneys' Fees. In the event of a dispute among the parties hereto
or in the event of any default hereunder, the party prevailing in the resolution
of any such dispute or default shall be entitled to recover its reasonable
attorneys' fees and other costs incurred in connection with resolving such
dispute or default.

         9.9 Notices. Any notices required by this Agreement shall be in
writing, shall specifically refer to this Agreement and shall be sent by
registered or certified airmail, postage prepaid, or by telefax, telex or cable,
charges prepaid, or by overnight

                                   X = -
                                      B, where

                                   X = the pro rata portion of Net Sales
                                   attributable to Scripps Patent Rights or
                                   other Scripps Technology licensed herein

                                   A = the fair market value of the component in
                                   the Combination Product utilizing Scripps
                                   Technology licensed hereunder, and

2.4      Quarterly Payments.

         2.4.1 Sales by Licensee. With regard to Net Sales made by Licensee or
its Affiliates, royalties shall be payable by Licensee quarterly, within sixty

Net Sales of Licensed Products by such sublicensee during such preceding
calendar quarter, commencing with the calendar quarter in which the first
commercial sale of any Licensed Product is made by such sublicensee.

         2.5 Term of License. Unless terminated sooner in accordance with the
provisions of this Agreement, the term of this license shall expire when the
last of the royalty obligations set forth has expired. Notwithstanding the
foregoing, if applicable government regulations require a shorter term and/or a
shorter term of exclusivity than provided for herein, then the term of this
License Agreement shall be so shortened or this License Agreement shall be
amended to provide for a non-exclusive license, and, in such event, the parties
shall negotiate in good faith to reduce appropriately the royalties payable as
set forth under the section heading "Royalties" hereof.

         2.6 Sublicense. Licensee shall have the sole and exclusive right to
grant sublicenses to any party with respect to the rights conferred upon
Licensee under this Agreement, provided, however, that any such sublicense shall
be subject in all respects to the restrictions, exceptions, royalty obligations,
reports, termination provisions, and other provisions contained in this
Agreement and shall not exceed the scope of the license granted to Licensee
hereunder. Promptly after execution of any sublicense agreement, Licensee shall
give written notice to Scripps of the grant of such sublicense and details of
the following material terms: (i) the name of the sublicensee, (ii) the duration
of the sublicense, (iii) the Scripps Patent Rights and Scripps Technology that
are the subject of the sublicense, and (iv) the commercialization obligations
imposed upon the sublicensee. Licensee shall pay Scripps, or cause its Affiliate
or sublicensee to pay Scripps, the same royalties on all Net Sales of such
Affiliate or sublicensee the same as if said Net Sales had been made by
Licensee. Each Affiliate and sublicensee shall report its Net Sales to Scripps
through Licensee, which Net Sales shall be aggregated with any Net Sales of
Licensee for purposes of determining the Net Sales upon which royalties are to
be paid to Scripps.

         2.7 Aggregate Royalties. In the event that a percentage of sublicense
income or royalties are paid by the Licensee, an Affiliate or a sublicensee to
an unaffiliated third party or to Scripps under a separate agreement in respect
of a Licensed Product ("Additional Royalties") for which royalties are also due
to Scripps pursuant to this Agreement, then the following provisions shall apply
(either separately or jointly, as applicable):

         (a) if the Licensed Product is or was claimed in whole or in part, in
one or more of the Core Patent Rights and the Additional Royalties are due
pursuant to a license agreement between Scripps and Licensee that is executed
pursuant to that certain Research Funding and Option Agreement of even date
herewith between Scripps and Licensee (such licenses are collectively referred
to herein as "Other Research Licenses"):



                                       5
<PAGE>
<PAGE>

         (i) until the expiration of the last to expire of the Core Patent
rights, the royalties under this Agreement shall be reduced such that the
aggregate royalties due under this Agreement and the Other Research Licenses do
not exceed Two and One-Half percent (2.5 %) of Net Sales of the Licensed
Product;

         (ii) after the expiration of the last to expire of the Core Patent
Rights, the royalties under this Agreement shall be increased such that the
aggregate royalties due under this Agreement and the Other Research Licenses do
not exceed Seven percent (7%) of Net Sales of the Licensed Product.

         (b) if the Licensed Product is or was claimed in whole or in part in
one or more of the Core Patent Rights and the Additional Royalties are due under
any license with a third party or any other license agreement between Licensee
and Scripps, or if the Licensed Product is or was not claimed in any of the Core
Patent Rights, then the royalties under this Agreement shall be reduced by the
amount of the payments due to the third party or Scripps under such license
agreements, subject to a maximum reduction of fifty percent (50%) of the
royalties due hereunder.

         2.8 Duration of Royalty Obligations. The royalty obligations of
Licensee as to each Licensed Product shall terminate on a country-by-country
basis concurrently with the expiration of the last to expire of Scripps Patent
Rights utilized by or in such Licensed Product in each such country or, with
respect to Licensed Products not utilizing any Scripps Patent Rights, ten (10)
years after the date of first commercial sale of such Licensed Product in such
country.

         2.9 Reports. Licensee shall furnish to Scripps at the same time as
each royalty payment is made by Licensee, a detailed written report of Net Sales
of the Licensed Products and the royalty due and payable thereon, including a
description of any offsets or credits deducted therefrom, on a
product-by-product and country-by-country basis, for the calendar quarter upon
which the royalty payment is based.

         2.10 Records. Licensee shall keep, and cause its Affiliates and
sublicensees to keep, full, complete and proper records and accounts of all
sales of Licensed Products in sufficient detail to enable the royalties payable
on Net Sales of each Licensed Product to be determined. Scripps shall have the
right to appoint an independent certified public accounting firm approved by
Licensee, which approval shall not be unreasonably withheld, to audit the
records of Licensee, its Affiliates and sublicensees as necessary to verify the
royalties payable pursuant to this Agreement. Licensee, its Affiliates and
sublicensees shall pay to Scripps an amount equal to any additional royalties to
which Scripps is entitled as disclosed by the audit, plus interest thereon at 
the rate of one and one-half percent (1.5%) per month. Such audit shall be at
Scripps' expense; provided, however, that if the audit discloses that Scripps
was underpaid royalties with respect to any Licensed Product by at least five
percent (5%) for any calendar quarter, then Licensee, its Affiliates or
sublicensee, as the case



                                       6
<PAGE>
<PAGE>

may be shall reimburse Scripps for any such audit costs. Scripps may exercise
its right of audit as to each of Licensee, its Affiliates or sublicensees no
more frequently than once in any calendar year. The accounting firm shall
disclose to Scripps only information relating to the accuracy of the royalty
payments. Licensee, its Affiliates and sublicensees shall preserve and maintain
all such records required for audit for a period of three (3) years after the
calendar quarter to which the record applies.

         2.11 Foreign Sales. The remittance of royalties payable on sales
outside the United States shall be payable to Scripps in United States Dollar
equivalents at the official rate of exchange of the currency of the country from
which the royalties are payable, as quoted in the Wall Street Journal for the
last business day of the calendar quarter in which the royalties are payable. If
the transfer of or the conversion into the United States Dollar equivalents of
any such remittance in any such instance is not lawful or possible, the payment
of such part of the royalties as is necessary shall be made by the deposit
thereof, in the currency of the county where the sale was made on which the
royalty was based to the credit and account of Scripps or its nominee in any
commercial bank or trust company of Scripps' choice located in that country,
prompt written notice of which shall be given by Licensee to Scripps.

         2.12 Foreign Taxes. Any tax required to be withheld by Licensee under
the laws of any foreign country for the accounts of Scripps shall be promptly
paid by Licensee for and on behalf of Scripps to the appropriate governmental
authority, and Licensee shall use its best efforts to furnish Scripps with proof
of payment of such tax together with official or other appropriate evidence
issued by the applicable government authority. Any such tax actually paid on
Scripps' behalf shall be deducted from royalty payments due Scripps.

3.       Patent Matters.

         3.1 Patent Prosecution and Maintenance. From and after the date of this
Agreement, the provisions of this Section 3 shall control the prosecution and
maintenance of any patent included within Scripps Patent Rights. Subject to the
requirements, limitations and conditions set forth in this Agreement, Scripps
shall direct and control (i) the preparation, filing and prosecution of the
United States and foreign patent applications within Scripps Patent Rights
(including any interferences and foreign oppositions) and (ii) maintain the
patents issuing therefrom. Scripps shall select the patent attorney, subject to
Licensee's written approval, which approval shall not be unreasonably withheld.
Both parties hereto agree that Scripps may, at its sole discretion, utilize
Scripps' Office of Patent Counsel in lieu of outside counsel for patent
prosecution and maintenance described herein, and the fees and expenses incurred
by Scripps with respect to work done by such Office of Patent Counsel shall be
paid as set forth below. Licensee shall have will rights of consultation with
the patent attorney so selected on all matters relating to Scripps Patent 
Rights. Scripps shall use its best efforts to implement all reasonable 
requests made by Licensee with regard to the preparation, filing,



                                       7
<PAGE>
<PAGE>

prosecution and/or maintenance of the patent applications and/or patents within
Scripps Patent Rights.

         3.2 Information to Licensee. Scripps shall keep Licensee informed with
regard to the patent application and maintenance processes. Scripps shall
deliver to Licensee copies of all patent applications, amendments, related
correspondence, and other related matters.

         3.3 Patent Costs. Licensee acknowledges and agrees that Scripps does
not have independent funding to cover patent costs, and that the license granted
hereunder is in part in consideration for Licensee's assumption of patent costs
and expenses as described herein. Licensee shall pay for all expenses incurred
by Scripps pursuant to Section 3.1 hereof. In addition, Licensee agrees to
reimburse Scripps for all patent costs and expenses paid or incurred by Scripps
to date in connection with Scripps Patent Rights licensed hereunder. Licensee
agrees to pay all such past and future patent expenses directly or to reimburse
Scripps for the payment of such expenses within sixty (60) days after Licensee
receives an itemized invoice therefor. In the event Licensee elects to
discontinue payment for the filing, prosecution and/or maintenance of any patent
application and/or patent within Scripps Patent Rights, any such patent
application or patent shall be excluded from the definition of Scripps Patent
Rights and from the scope of the license granted under this Agreement, and all
rights relating thereto shall revert to Scripps and may be freely licensed by
Scripps. Licensee shall give Scripps at least sixty (60) days' prior written
notice of such election. No such notice shall have any effect on Licensee's
obligations to pay expenses incurred up to the effective date of such election.

         3.4 Ownership. The patent applications filed and the patents obtained
by Scripps pursuant to Section 3.1 hereof shall be owned solely by Scripps,
assigned to Scripps and deemed a part of Scripps Patent Rights.

         3.5 Scripps Right to Pursue Patent. If at any time during the term of
this Agreement, Licensee's rights with respect to Scripps Patent Rights are
terminated, Scripps shall have the right to take whatever action Scripps deems
appropriate to obtain or maintain the corresponding patent protection at its own
expense. If Scripps pursues patents under this Section 3.5, Licensee agrees to
cooperate fully, including by providing, at no charge to Scripps, all
appropriate technical data and executing all necessary legal documents.

         3.6 Licensee's Right to Pursue Patent. If subsequent to filing a
patent application on an invention within the Scripps Patent Rights, Scripps
elects not to direct and control the prosecution or maintenance of such patent
application or ensuing patent Scripps shall give Licensee notice thereof within
a reasonable period prior to allowing such patent application or patent to lapse
or become abandoned or unenforceable and Licensee may direct and control
prosecution or maintenance of such patent application or patent at its expense
and its exclusive benefit. If subsequent to filing of a United States patent
application,



                                       8
<PAGE>
<PAGE>

Scripps chooses not to file in foreign countries, Scripps shall inform Licensee
within six (6) months of the United States filing date and shall permit Licensee
to effect such foreign filings not made by Scripps at Licensee's sole expense.

3.7      Infringement Actions.

         3.7.1 Prosecution of Infringements. Scripps and Licensee shall promptly
notify the other in writing if any infringement of the Scripps Patent Rights by
a third party is discovered or comes to its attention. Provided Licensee shall
have supplied Scripps with reasonable evidence of infringement of Scripps Patent
Rights by a third party, Licensee shall have the right, at Licensee's sole
expense to bring suit against the infringer for infringement of the Scripps
Patent Rights. In the event that Licensee has not caused such infringement to
terminate (for whatever cause) or initiated legal proceedings against the
infringer within three (3) months following receipt or giving of notice pursuant
to this Section 3.7, Scripps shall have the right (but not the obligation), at
Scripps's sole expense, to bring suit against the infringer for infringement of
the Scripps Patent Rights.

         3.7.2 Reasonable Assistance. In the event either party hereto shall
initiate or carry on legal proceedings to enforce the Scripps Patent Rights
against an alleged infringer, as provided herein, the other party hereto shall
render reasonable assistance to and cooperate with the party initiating or
carrying on such proceedings.

         3.7.3 Control. In the event that either party shall institute suit or
other legal proceedings to enforce the Scripps Patent Rights, it shall have sole
control of such suit and the other party shall be entitled to be represented in
any such suit by counsel of its choosing, at its sole expense. Licensee shall
not discontinue or settle any such proceedings brought by it without obtaining
the concurrence of Scripps (which concurrence shall not be unreasonably
withheld) and giving Scripps a timely opportunity to continue such proceedings
in its own name, under its sole control, and at this sole expense. In the event
Scripps does not concur in such settlement, it must continue such proceeding in
its own name, under its sole control and expense within three (3) months of
being given notice by Licensee of its desire to settle or Licensee shall be
entitled to settle without Scripps's concurrence.

licensed hereunder into commercially viable Licensed Products, and thereafter
to produce and sell reasonable quantities of Licensed Products. Licensee shall
keep Scripps generally informed as to Licensee's progress in such development,
production and sale, including its efforts, if any and only to the extent it may
do so without breaching the terms of any confidentiality agreement, to

to Scripps a semi-annual written report and such other reports as Scripps may
reasonably request. The parties hereto acknowledge and agree that achievement of
the milestones described in Exhibit C attached hereto on or before the dates set

development obligations hereunder for the time periods specified in Exhibit C.
In the event Scripps has a reasonable basis to believe that Licensee is not
using reasonable efforts and due diligence as required hereunder, upon notice by
Scripps to Licensee which specifies the basis for such belief, Scripps and
Licensee shall negotiate in good faith to attempt to mutually resolve the issue.
In the event Scripps and Licensee cannot agree upon any matter related to
Licensee's commercial development obligations, the parties agree to utilize
arbitration pursuant to Section 10.2 hereof in order to resolve the matter. If
the arbitrator determines that Licensee has not complied with its obligations
hereunder, and such default is not fully cured within sixty (60) days after the
arbitrator's decision, Scripps may terminate Licensee's rights under this
Agreement.

         4.2 Governmental Approvals and Marketing of Licensed Products.
Licensee shall be responsible for obtaining all necessary governmental approvals
for the development, production, distribution, sale and use of any Licensed
Product, at Licensee's expense, including, without limitation, any safety
studies. Licensee shall have sole responsibility for any warning labels,
packaging and instructions as to the use of Licensed Products and for the
quality control for any Licensed Product.

against any liability or expense arising from any product liability claim
asserted by any party as to any Licensed Product or


                                       10
<PAGE>
<PAGE>

any claims arising from the use of any Scripps Patent Rights or Scripps
Technology pursuant to this Agreement. Such indemnity and defense obligation
shall apply to any product liability or other claims, including without
limitation, personal injury, death or property damage, made by employees,
subcontractors, sublicensees, or agents of Licensee, as well as any member of
the general public. Licensee shall use its best efforts to have Scripps and, if
requested in writing by Scripps, any parent, subsidiary or other affiliated
entity of Scripps and their trustees, officers, employees, scientists and agents
named as additional insured parties on any product liability insurance policies
maintained by Licensee its Affiliates and sublicensees applicable to Licensed
Products.

         4.4 Patent Marking. To the extent required by applicable law, Licensee
shall mark all Licensed Products or their containers in accordance with the
applicable patent marking laws.

         4.5 No Use of Name. The use of the name "The Scripps Research

advertising or sale of Licensed Products is expressly prohibited.

         4.6 U.S. Manufacture. To the extent required by applicable United
States laws, if at all, Licensee agrees that Licensed Products will be
manufactured in the United States, or its territories, subject to such waivers
as may be required, or obtained, if at all, from the United States Department of
Health and Human Services, or its designee.

         4.7 Foreign Registration. Licensee agrees to register this Agreement
with any foreign governmental agency which requires such registration, and
Licensee shall pay all costs and legal fees in connection therewith. In
addition, Licensee shall assure that all foreign laws affecting this Agreement
or the sale of Licensed Products are fully satisfied.

         5. Limited Warranty. Scripps hereby represents and warrants that it has
full right and power to enter into this Agreement and grant the licenses to
Licensee granted herein. SCRIPPS MAKES NO OTHER WARRANTIES CONCERNING SCRIPPS
PATENT RIGHTS OR SCRIPPS TECHNOLOGY COVERED BY THIS AGREEMENT, INCLUDING WITHOUT

         9.2 Binding Upon Successors and Assigns. Subject to the limitations on
assignment herein, this Agreement shall be binding upon and inure to the benefit
of any successors in interest and assigns of Scripps and Licensee. Any such
successor or assignee of Licensee's interest shall expressly assume in writing
the performance of all the terms and conditions of this Agreement to be
performed by Licensee.

10.      General Provisions.

         10.1 Independent Contractors. The relationship between Scripps and
Licensee is that of independent contractors. Scripps and Licensee are not joint
venturers, partners, principal and agent, master and servant, employer or
employee, and have no other relationship other than independent contracting
parties. Scripps and Licensee shall have no power to bind or obligate each other
in any manner, other than as is expressly set forth in this Agreement.

         10.2 Arbitration. Any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by binding
arbitration in accordance with the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"), and the procedures set forth below. In the
event of any inconsistency between the Rules of AAA and the procedures set forth
below, the procedures set forth below shall control. Judgment upon the award
rendered by the arbitrators may be enforced in any court having jurisdiction
thereof.

         10.2.1 Location. The location of the arbitration shall be in the City
of Philadelphia.

         10.2.2 Selection of Arbitrators. The arbitration shall be conducted by
a panel of three neutral arbitrators who are independent and disinterested with
respect to the parties, this Agreement, and the outcome of the arbitration. Each
party shall appoint one neutral arbitrator, and these two arbitrators so
selected by the parties shall then select the third arbitrator. If one party has
given written notice to the other party as to the identity of the arbitrator
appointed by the party, and the party thereafter makes a written demand on the
other party to appoint its designated arbitrator within the next ten days, and
the other party fails to appoint its designated arbitrator within ten days after
receiving said written demand, then the arbitrator who has already been
designated shall appoint the other two arbitrators.

         10.2.3 Discovery. Unless the parties mutually agree in writing to some
additional and specific pre-hearing discovery, the only pre-hearing discovery
shall be (a) reasonably limited production of relevant and non-privileged
documents, and (b) the identification of witnesses to be called at the hearing,
which identification shall give the witness's name, general qualifications and
position, and a brief statement as to the general scope of the testimony to be
given by the witness. The arbitrators shall decide any disputes



                                       15
<PAGE>
<PAGE>

and shall control the process concerning these pre-hearing discovery matters.
Pursuant to the Rules of AAA, the parties may subpoena witnesses and documents
for presentation at the hearing.

         10.2.4 Case Management. Prompt resolution of any dispute is important
to both parties; and the parties agree that the arbitration of any dispute shall
be conducted expeditiously. The arbitrators are instructed and directed to
assume case management initiative and control over the arbitration process
(including scheduling of events, pre-hearing discovery and activities, and the
conduct of the hearing), in order to complete the arbitration as expeditiously
as is reasonably practical for obtaining a just resolution of the dispute.

         10.2.5 Remedies. The arbitrators may grant any legal or equitable
remedy or relief that the arbitrators deem just and equitable, to the same
extent that remedies or relief could be granted by a state or federal court,
provided however, that no punitive damages may be awarded. No court action may
be maintained seeking punitive damages. The decision of any two of the three
arbitrators appointed shall be binding upon the parties.

         10.2.6 Expenses. The expenses of the arbitration, including the
arbitrators' fees, expert witness fees, and attorney's fees, may be awarded to
the prevailing party, in the discretion of the arbitrators, or may be
apportioned between the parties in any manner deemed appropriate by the
arbitrators. Unless and until the arbitrators decide that one party is to pay
for all (or a share) of such expenses, both parties shall share equally in the
payment of the arbitrators' fees as and when billed by the arbitrators.

         10.2.7 Confidentiality. Except as set forth below, the parties shall
keep confidential the fact of the arbitration, the dispute being arbitrated, and
the decision of the arbitrators. Notwithstanding the foregoing, the parties may
disclose information about the arbitration to persons who have a need to know,
such as directors, trustees, management employees, witnesses, experts,
investors, attorneys, lenders, insurers, and others who may be directly
affected. Additionally, if a party has stock which is publicly traded, the party
may make such disclosures as are required by applicable securities laws.
Further, if a party is expressly asked by a third party about the dispute or
the arbitration, the party may disclose and acknowledge in general and limited
terms that there is a dispute with the other party which is being (or has been)
arbitrated. Once the arbitration award has become final, if the arbitration
award is not promptly satisfied, then these confidentiality, provisions shall no
longer be applicable.

         10.3 Entire Agreement: Modification. This Agreement sets forth the
entire agreement and understanding between the parties as to the subject matter
hereof. There shall be no amendments or modifications to this Agreement, except
by a written document which is signed by both parties.

         10.4 California Law. This Agreement shall be construed and enforced in
accordance with the laws of the State of California.

         10.5 Headings. The headings for each article and section in this
Agreement have been inserted for convenience of reference only and are not
intended to limit or expand on the meaning of the language contained in the
particular article or section.

         10.6 Severability. Should any one or more of the provisions of this
Agreement be held invalid or unenforceable by a count of competent jurisdiction,
it shall be considered severed from this Agreement and shall not serve to
invalidate the remaining provisions thereof. The parties shall make a good faith
effort to replace any invalid or unenforceable provision with a valid and
enforceable one such that the objectives contemplated by them when entering this
Agreement may be realized.

         10.7 No Waiver. Any delay in enforcing a party's rights under this
Agreement or any waiver as to a particular default or other matter shall not
constitute a waiver of such party's rights to the future enforcement of its
rights under this Agreement, excepting only as to an express written and signed
waiver as to a particular matter for a particular period of time.

         10.8 Name. Whenever there has been an assignment or a sublicense by
Licensee as permitted by this Agreement, the term "Licensee" as used in this
Agreement shall also include and refer to, if appropriate, such assignee or
sublicensee.

         10.9 Attorneys' Fees. In the event of a dispute between the parties
hereto or in the event of any default hereunder, the party prevailing in the
resolution of any such dispute or default shall be entitled to recover its
reasonable attorneys' fees and other costs incurred in connection with resolving
such dispute or default.

         10.10 Notices. Any notices required by this Agreement shall be in
