                               PROSPECTUS SUMMARY
 
     The  following summary is qualified in its  entirety by, and should be read
in conjunction with, the more detailed information and the financial  statements
and  notes  thereto appearing  elsewhere  in this  Prospectus.  Unless otherwise
indicated, all information in  the Prospectus (i) gives  effect to a  8.30-for-1
stock  split in  the form  of a stock  dividend declared  in May  1996, and (ii)
assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY

     Algos Pharmaceutical Corporation ('Algos' or the 'Company') is a leader  in
developing a new generation of proprietary pain management products. The Company
develops   its  proprietary  pain  management  products  by  combining  existing
analgesic or  anesthetic  drugs with  N-methyl-D-aspartate  ('NMDA')  antagonist
drugs  that have been approved for  human use in other applications. Independent
research and the Company's pre-clinical studies and clinical trials conducted to
date have  shown that  the  Company's products  may significantly  improve  pain
relief  over currently  available analgesics,  including narcotic  drugs such as
morphine,  hydrocodone  and  oxycodone  and  non-narcotic  analgesics  such   as
acetaminophen  (e.g. Tylenol'r'),  ibuprofen (e.g. Advil'r')  and naproxen (e.g.
Aleve'r'). The Company is  also developing a local  anesthetic product that  has
the  potential  to  provide  greater  anesthetic  effect  with  longer  and more
controlled  duration  than  existing  products.  The  Company's  analgesic   and
anesthetic  products will target markets with combined 1995 U.S. sales estimated
at $6.4  billion.  In  addition,  the  Company  is  using  its  NMDA  antagonist
technology to develop products to treat urge urinary incontinence and opiate and
cocaine addiction.

 
     The  Company believes that  its analgesic and  anesthetic products have the
potential for more rapid market introduction  than many other new drugs  because
(i) the Company's products combine existing drugs whose separate safety profiles
are  known  and established  and  (ii) clinical  trials  for new  analgesics and
anesthetics historically have  achieved statistically  significant results  with
fewer  patients than  may be  required for  many other  drugs. As  a result, the
Company currently anticipates that it will  file its first New Drug  Application
('NDA') with the Food and Drug Administration ('FDA') in 1997.
 

     The  Company has ten products that have reached Phase II clinical trials or
are scheduled for Phase II or Phase III clinical trials in 1996. The Company has
completed or is currently  conducting eleven clinical  trials and has  scheduled
additional  clinical trials  to commence  in 1996.  A pivotal  Phase II clinical
efficacy trial has been completed with MorphiDex'tm' demonstrating statistically
significant superior pain relief over morphine.

 

     The Company's products that  have reached Phase II  clinical trials or  are
scheduled for Phase II or Phase III clinical trials consist of:

 
      (i) four   narcotic   analgesic/NMDA   antagonist   combination  products:
          MorphiDex'tm', expected to  be used  primarily to  treat cancer  pain,
          HydrocoDex  SR'tm'  and  HydrocoDex  Plus'tm',  expected  to  be  used
          primarily to  treat  moderate  to  moderately  severe  post-operative,
          musculoskeletal and trauma-related pain, and OxycoDex'tm', expected to
          be   used   primarily   to  treat   moderate   to   moderately  severe
          post-operative pain;
 
      (ii) two over-the-counter  ('OTC') analgesic/NMDA  antagonist  combination
           products:   a  combination   product  of  an   NMDA  antagonist  with
           acetaminophen, the largest selling  OTC analgesic, and a  combination
           product of an NMDA antagonist with ibuprofen, the largest selling OTC
           non-steroidal anti-inflammatory drug ('NSAID');
 

     (iii) one  injectable local anesthetic/NMDA combination product intended to
           provide greater  anesthetic effect  with longer  and more  controlled
           duration  for use in dental procedures and in-patient and out-patient
           surgeries;

 
      (iv) one product that uses an NMDA antagonist intended as a treatment  for
           urge  urinary incontinence,  a condition which  afflicts an estimated
           five million people in the U.S.; and
 

      (v) two products intended as treatments for opiate and cocaine  addiction,
          which  the  Company  expects  to  develop  in  collaboration  with the
          National Institute  on Drug  Abuse  ('NIDA'), National  Institutes  of
          Health ('NIH').

 

     In  June 1996,  the Company  entered into  a license  agreement with McNeil
Consumer Products  Company  ('McNeil'),  an  affiliate  of  Johnson  &  Johnson,
pursuant  to which  the Company  granted McNeil  the exclusive  right to develop
acetaminophen/NMDA  antagonist  combination  products  and  certain   NSAID/NMDA
antagonist  combination products for the treatment  of pain (the 'McNeil License
Agreement'). The  McNeil  License  Agreement: (i)  grants  McNeil  an  exclusive
worldwide  license to manufacture and market such products; (ii) provides for an
initial payment of $2.0 million to

 
                                       3

the Company and subsequent payments of up to an additional $8.0 million upon the
achievement of certain milestones generally relating to product development  and
patent issuances; and (iii) provides for the payment of royalties to the Company
on  net sales  of the licensed  products. McNeil will  bear all of  the costs of
developing products it selects, except for approximately $500,000 to be borne by
the Company. McNeil  will be required  to pay minimum  royalties, provided  that
certain  conditions have been met, even if McNeil has not commenced marketing of
an acetaminophen product or an NSAID product.

 

     In June 1996, the Company entered into  a letter of intent with NIDA,  NIH,
pending  formal approval of a cooperative  research and development agreement (a
'CRADA'), to conduct joint research  on a methadone/NMDA antagonist  combination
drug as a potential treatment for opiate addiction.

 
     The  Company believes that the markets in which it intends to compete offer
attractive opportunities.  Favorable factors  in  the target  analgesic  markets
include:  high  growth  rates  partially  attributable  to  the  rapidly growing
population segment aged 65 and older; increasing recognition of the  therapeutic
benefits  of  effective  pain  treatment  including  reductions  in  healing and
recovery time;  generally concentrated  distribution channels  that permit  more
cost-effective  selling and marketing;  lack of recent  product innovation which
has resulted in  market segments  comprised largely of  older off-patent  drugs;
higher  profit margins from branded proprietary  products; and the potential for
rapid acceptance  of  new pain  management  pharmaceuticals by  members  of  the
medical  profession. The market  for local anesthetics  also presents attractive
opportunities for  the Company's  controlled duration  product because  existing
local  anesthetics have limited  and less controllable  duration which restricts
their use in surgery. The Company believes the markets for its products to treat
urge urinary incontinence and  drug addiction present significant  opportunities
because  of the  lack of  satisfactory pharmaceutical  treatments and  the large
potential market sizes.
 
     The Company's strategic goal is to establish a leading position in the pain
management pharmaceutical market. The Company  intends to achieve this goal  by:
(i) introducing superior proprietary products; (ii) minimizing development time,
cost  and  risk; (iii)  leveraging  its proprietary  technology  across multiple
product opportunities; (iv) outsourcing to efficiently deploy resources; and (v)
maximizing market  penetration and  margin potential  through a  combination  of
Company direct sales and strategic alliances.


 
     The  Company  seeks to  protect its  proprietary  position by,  among other
methods, filing United States  and foreign patent  applications with respect  to
the  development of its  products. The Company has  exclusive licenses for three
issued U.S.  patents and  six U.S.  patent applications  pending and  holds  one
additional U.S. patent application pending.
 

     To  date, the Company has generated no product revenues and has experienced
net losses in each year since its  inception. At June 30, 1996, the Company  had
an accumulated deficit of approximately $4.9 million.

 
     The Company was incorporated in Delaware in 1992. Its executive offices are
located  at Collingwood Plaza, 4900 Route 33, Neptune, New Jersey 07753, and its
telephone number is (908) 938-5959.

                                  RISK FACTORS
 
     An  investment in the shares of Common Stock offered hereby involves a high
degree of risk. The following factors,  in addition to the other information  in
this  Prospectus, should be  carefully considered in  evaluating the Company and
its business before purchasing the shares of Common Stock offered hereby.
 
Early Stage of the Company; Continuing Losses; Uncertainty of Future
Profitability
 

     Since its formation in January 1992, the Company has been engaged primarily
in organizational and start-up  activities, conducting research and  development
programs,   recruiting  officers   and  key  scientists,   and  negotiating  and
consummating technology licensing  and research agreements.  The Company has  no
revenues  from product  sales and no  history of manufacturing  or marketing. To
date, substantially all  of its funding  has been provided  by contributions  of
capital  made by its founders, through a  private placement of 700,000 shares of
its Series A Preferred Stock and an initial payment from McNeil pursuant to  the
McNeil  License Agreement. There can be no  assurance that the Company will have
any source of product  revenue or that its  operations will eventually  generate
sufficient revenues to achieve profitability. The Company has experienced losses
since  its inception. The  Company had accumulated  losses of approximately $4.9
million through June  30, 1996, and  losses are continuing  and are expected  to
continue  for  the  foreseeable future.  Therefore,  the Company  has  a limited
history upon which investors may base  an evaluation of its likely  performance.
The  Company's prospects must be considered  in light of the problems, expenses,
complications and delays frequently encountered in connection with the formation
of a new  business, the  development of new  pharmaceutical products,  including
obtaining  the  necessary  regulatory  approvals,  the  utilization  of unproven
technology and  the  competitive  environment  in which  the  Company  plans  to
operate.

 

Uncertainty Associated with Pre-Clinical Studies and Clinical Trials

 

     In  order to receive regulatory approval to sell its products commercially,
the Company must demonstrate  in pre-clinical studies  and clinical trials  that
its  potential products are safe and effective in humans. To date, four clinical
trials have  been completed  on  two of  the  Company's products.  Although  the
results  of the  Company's initial pre-clinical  studies and  clinical trials to
date have  been encouraging,  the results  of initial  pre-clinical studies  and
clinical  trials  are  not by  themselves  predictive  of results  that  will be
obtained from subsequent or more extensive trials. Furthermore, there can be  no
assurance  that clinical trials  of products under  development will demonstrate
the safety  and efficacy  of such  products to  the extent  necessary to  obtain
regulatory  approvals. Many  pharmaceutical companies  have suffered significant
setbacks in advanced clinical  trials, even after  promising results in  earlier
trials.  The  failure to  adequately demonstrate  the safety  and efficacy  of a
product could delay  or prevent regulatory  approval of such  product and  could
have a material adverse effect on the Company.

 
     The  rate of completion  of clinical trials is  dependent upon, among other
factors, the  enrollment of  patients. Patient  accrual is  a function  of  many
factors, including the size of the patient population, the proximity of patients
to  clinical sites, the eligibility criteria for  the study and the existence of
competitive clinical  trials.  Delays  in  planned  patient  enrollment  in  the
Company's  current  trials or  future clinical  trials  may result  in increased
costs, program delays or both, which could have a material adverse effect on the
Company. There can  be no assurance  that if clinical  trials are completed  the
Company  will be able to submit an NDA as scheduled or that any such application
will be reviewed  and approved by  the FDA in  a timely manner,  or at all.  See
'Business -- Government Regulation.'
 
Uncertainty of Market Acceptance
 

     Even if regulatory approvals are obtained, uncertainty exists as to whether
the  Company's products will be accepted by  the market. A number of factors may
limit the market acceptance of the  Company's products, including the timing  of
regulatory  approvals  and market  entry relative  to competitive  products, the
availability of  alternative  products,  the price  of  the  Company's  products
relative  to alternative products, the availability of third-party reimbursement
and the  extent  of marketing  efforts  by third-party  distributors  or  agents
retained  by the Company. There can be no assurance of the Company's ability, or
the length  of time  required, to  achieve market  acceptance of  the  Company's

 
                                       6

products.  In  addition,  certain  of the  Company's  products  contain narcotic
ingredients  that  may  require  stringent  record-keeping  obligations,  strict
storage  requirements and other limitations  on such products' availability that
may limit  the  commercial usage  of  such  products. See  'Business  --  Market
Overview' and ' -- Products.'
 

Certain Risks Associated With the McNeil License Agreement

 

     The  McNeil License Agreement extends until  the later of the expiration of
the Company's patent rights  or ten years from  the date of execution,  provided
that  the McNeil  License Agreement  is terminable: (i)  by either  party in the
event of a breach by the other party upon 90 days notice or upon certain  events
of  bankruptcy; (ii) by  McNeil, at any  time after one  year from the effective
date  of  the  agreement;   and  (iii)  by  the   Company  upon  certain   other
circumstances.  Under certain circumstances, the  McNeil License Agreement could
terminate with  respect  to  either  acetaminophen  or  NSAID  products  without
terminating with respect to the other category. In the event of a termination by
McNeil, McNeil must pay all royalty payments and milestone payments due, if any,
through the date of termination and the technology licensed by McNeil reverts to
the Company. In such event, the Company retains the rights to the results of the
two clinical studies funded by the Company, and McNeil retains the rights to the
results  of the clinical studies funded by  McNeil during the term of the McNeil
License Agreement.

 
Competition and Technological Changes, Uncertainty and Obsolescence
 
     The  Company's  success  will  depend,   in  part,  upon  its  ability   to
successfully  achieve market  share at the  expense of  existing and established
products in  the  Company's  target  markets. The  Company's  products  will  be
competing  directly with the products of companies that are well-established and
which may have a significantly higher  degree of brand and name recognition  and
substantially more financial resources than those of the Company. The Company is
also  in competition  with other  pharmaceutical companies,  hospitals, research
organizations, individual scientists and non-profit organizations engaged in the
development of new pain management pharmaceuticals. Many of these companies  and
entities   have  greater   research  and   development  capacities,  experience,
recognition and marketing, financial and  managerial resources than the  Company
and  represent  significant competition  for  the Company.  Also,  the Company's
competitors may succeed in developing  competing technologies and obtaining  FDA
approval  for products more rapidly than the  Company. There can be no assurance
that  developments  by  others  will  not  render  the  Company's  products   or
technologies non-competitive or obsolete.
 
Government Regulation; No Assurance of United States or Foreign Regulatory
Approval
 
     The  FDA and  comparable agencies  in foreign  countries impose substantial
requirements on the introduction of therapeutic pharmaceutical products  through
lengthy  and  detailed  laboratory and  clinical  testing and  other  costly and
time-consuming procedures. Satisfaction of these requirements typically takes  a
number  of  years,  varies substantially  based  upon the  type,  complexity and
novelty of the pharmaceutical products and is subject to uncertainty. Government
regulation  also  affects  the  manufacture  and  marketing  of   pharmaceutical
products.  Regulatory approvals, if granted, may include significant limitations
on the indicated  uses for which  a product  may be marketed.  The FDA  actively
enforces  regulations prohibiting  marketing of products  for non-indicated use.
Failure to comply with applicable  regulatory requirements can result in,  among
other  things, government imposed  fines, suspensions of  approvals, seizures or
recalls  of  products,   operating  restrictions   and  criminal   prosecutions.
Furthermore,  changes  in existing  regulations or  adoption of  new regulations
could prevent  the Company  from  obtaining, or  affect  the timing  of,  future
regulatory  approvals.  The  effect of  government  regulation may  be  to delay
marketing of the Company's  new products for a  considerable period of time,  to
impose  costly  procedures  upon  the  Company's  activities  and  to  furnish a
competitive advantage to larger companies  that compete with the Company.  There
can  be no  assurance that  FDA or  other regulatory  approval for  any products
developed by the Company will be granted on a timely basis, if at all. Any  such
delay  in obtaining, or failure to obtain, such approvals would adversely affect
the marketing of  the Company's  products and  the ability  to generate  product
revenue.  The Company is also subject to certain Drug Enforcement Agency ('DEA')
regulations, including restrictions on storage,
 
                                       7
 
<PAGE>
<PAGE>
transportation  and  administration,  for  its  narcotic  products.   Government
regulation  may  increase  at  any time,  creating  additional  hurdles  for the
Company. The extent  of potentially  adverse government  regulation which  might
arise  from future legislation or administrative action cannot be predicted. See
'Business -- Government Regulation.'
 
Need for Additional Funds
 

     The amount and  timing of  the Company's  expenditures will  depend on  the
progress  of its  research and  development, the  cost and  timing of regulatory
approvals, general  market conditions,  relationships with  potential  strategic
partners,  changes  in the  focus and  direction of  the Company's  research and
development programs, competitive and technological advances and other  factors.
The  Company's cash requirements may vary  materially from those now planned and
no assurance can  be given that  development costs will  not exceed the  amounts
budgeted  for such purposes. The Company  may require additional funding for its
research  and  product  development  programs,  operating  expenses,  regulatory
clearances  and sales and marketing expenses. Adequate funds for these purposes,
whether obtained through  financial markets  or through  collaborative or  other
arrangements  with partners  or from  other sources,  may not  be available when
needed or on terms acceptable to the Company. Insufficient funds may require the
Company  to  delay,  scale  back  or  eliminate  certain  of  its  research  and
development programs or to make arrangements with third parties to commercialize
products  or  technologies  that the  Company  would otherwise  seek  to develop
itself. As a result, the Company may not be able to independently develop any or
all of the  products described  in this Prospectus.  To the  extent the  Company
raises  additional capital by issuing  securities, further dilution to investors
may result.

 
Limited Sales and Marketing Experience
 

     The Company  intends  to  market  and sell  certain  of  its  products,  if
successfully  developed and approved, through a direct sales force in the United
States. The Company currently has no marketing  and sales staff, and has yet  to
establish  any product  distribution channels. In  order to  market its products
directly, the Company must develop a sales force with technical expertise. There
can be no assurance that  the Company will be  able to successfully establish  a
direct sales organization or distribution channels. Failure to establish a sales
force capability in the U.S. may have a material adverse effect on the Company.

 
Dependence on Qualified Personnel
 

     Because of the specialized scientific nature of the Company's business, the
Company  is highly  dependent upon its  ability to attract  and retain qualified
scientific and  technical  personnel. The  loss  of significant  scientific  and
technical  personnel or  the failure  to recruit  additional key  scientific and
technical personnel could have a material  adverse effect on the Company.  While
the   Company  has  consulting  agreements  with  certain  key  individuals  and
institutions and has employment agreements with its key executives, there can be
no assurance that the Company will be successful in retaining such personnel  or
their  services under  existing agreements.  See 'Management  and Key Scientific
Advisors' and ' -- Executive  Compensation and Employment Agreements.' The  loss
of  John  Lyle, the  Company's Chief  Executive Officer,  could have  a material
adverse effect on the  Company. The Company currently  maintains a $6.0  million
life  insurance policy on  Mr. Lyle. There is  intense competition for qualified
personnel in  the  areas  of the  Company's  activities,  and there  can  be  no
assurance  that the Company will  be able to continue  to attract and retain the
qualified personnel necessary for the development of its business.

 
Uncertain Ability to Protect Proprietary Technology
 
     The Company's success, competitive position and amount of potential  future
income  will depend in part on its  ability to obtain patent protection relating
to the technologies, processes and products it is developing and may develop  in
the  future.  The Company's  policy  is to  seek  patent protection  and enforce
intellectual property rights. With  respect to its  products, the Company  holds
one  U.S. patent application pending and has exclusive licenses for three issued
U.S. patents and six U.S. patent
 
                                       8
 
<PAGE>
<PAGE>
applications pending.  No assurance  can  be given  that  any patent  issued  or
licensed  to the Company will provide protection against competitive products or
otherwise be  commercially  viable.  In  this regard,  the  patent  position  of
pharmaceutical compounds and compositions is particularly uncertain. Even issued
patents  may  later be  modified  or revoked  by  the United  States  Patent and
Trademark Office ('PTO') or in legal proceedings. Moreover, the Company believes
that obtaining foreign  patents may  be more difficult  than obtaining  domestic
patents  because  of differences  in patent  laws,  and accordingly,  its patent
position may be stronger in the  U.S. than abroad. In addition, foreign  patents
may  be more  difficult to  protect and/or  the remedies  available may  be less
extensive than in  the U.S. Patent  applications in the  U.S. are maintained  in
secrecy  until  patents  issue  and, since  publication  of  discoveries  in the
scientific or  patent literature  tends to  lag behind  actual discoveries,  the
Company  cannot  be certain  that it  was  the first  creator of  the inventions
covered by pending patent applications or the first to file patent  applications
on  such inventions. No assurance can be given that any of the Company's pending
patent applications will  be allowed, or  if allowed, whether  the scope of  the
claims allowed will be sufficient to protect the Company's products.
 
     The  Company also expects to rely  upon trade secrets, know-how, continuing
technological innovations and  licensing opportunities to  develop and  maintain
its  competitive  position.  There can  be  no  assurance that  others  will not
independently develop  substantially equivalent  proprietary information  or  be
issued  patents that may prevent the sale  of the Company's products or know-how
or require licensing  and the payment  of significant fees  or royalties by  the
Company  in order to produce  its products. Moreover, there  can be no assurance
that the Company's technology does not infringe upon any valid claims of patents
owned by others. If the Company were found to be infringing on a patent held  by
another,  the  Company  might  have  to  seek  a  license  to  use  the patented
technology. There can be  no assurance that, if  required, the Company would  be
able  to obtain such a license on terms acceptable to the Company, if at all. If
a legal action  were to be  brought against  the Company or  its licensors,  the
Company  could incur substantial costs in defending  itself, and there can be no
assurance that such an action would be resolved in the Company's favor. If  such
a  dispute were to be resolved against the Company, the Company could be subject
to significant damages and the  testing, manufacture or sale  of one or more  of
the  Company's  technologies  or  proposed  products,  if  developed,  could  be
enjoined.
 
     No assurance can be given as to  the degree of protection any patents  will
afford,  whether patents will be  issued or whether the  Company will be able to
avoid violating or infringing upon patents issued to others. Despite the use  of
confidentiality  agreements and non-compete agreements,  which themselves may be
of limited effectiveness,  it may be  difficult for the  Company to protect  its
trade  secrets. See 'Business -- Patents,  Trade Secrets and Licenses' and 'Risk
Factors -- Dependence on Qualified Personnel.'
 
Uncertain Availability of Health Care Reimbursement
 
     The Company's ability  to commercialize  its pain  management products  may
depend  in  part on  the extent  to which  reimbursement for  the costs  of such
products will be  available from government  health administration  authorities,
private  health insurers and others. There  can be no assurance that third-party
insurance coverage will be  adequate for the Company  to establish and  maintain
price  levels  sufficient  for  realization  of  an  appropriate  return  on its
investment. Government,  private  insurers  and  other  third-party  payers  are
increasingly  attempting to contain health care  costs by limiting both coverage
and the level of  reimbursement for new products  approved for marketing by  the
FDA and by refusing, in some cases, to provide any coverage for uses of approved
products  for indications for which the  FDA has not granted marketing approval.
If adequate coverage and reimbursement levels are not provided by government and
third-party payers for uses of the Company's products, the market acceptance  of
these products could be adversely affected.
 
No Product Liability Insurance
 

     The Company will be exposed to potential product liability risks, which are
inherent  in  the  testing,  manufacturing and  marketing  of  human therapeutic
products. The Company is  contractually obligated under  certain of its  license
agreements  to indemnify  the individuals and/or  institutions from  whom it has

 
                                       9
 
<PAGE>
<PAGE>

licensed the technology against claims relating  to the manufacture and sale  of
the products to be sold by the Company. McNeil, however, has agreed to indemnify
the  Company for third party claims or suits resulting from the manufacture, use
or sale of the products pursuant to the McNeil License Agreement. The  Company's
indemnification  liability, as  well as  direct liability  to consumers  for any
defects in the products sold, could  expose the Company to substantial risk  and
losses.  Because the Company's  products are still  in their development stages,
the Company has not purchased any product liability insurance. The Company plans
to purchase such product  liability insurance as it  deems appropriate prior  to
marketing  its products. McNeil  is required by the  McNeil License Agreement to
maintain  product  liability  insurance  and   may  self-insure  to  cover   its
indemnification  obligations to the Company. However,  there can be no assurance
that the Company will be able to obtain or maintain such insurance on acceptable
terms or  that any  insurance obtained  will provide  adequate coverage  against
potential liabilities.

 
Concentration of Ownership
 

     Upon  completion of the Offering, the Company's directors and officers will
beneficially own  approximately 23.9%  of the  Common Stock.  In addition,  upon
completion  of the Offering, the Company's  largest stockholder, Unifina AG, and
related investors will  control approximately 11.0%  of the Common  Stock. As  a
result,  these stockholders, if  they acted together, would  have the ability to
influence significantly the election of the  Company's directors as well as  the
management and policies of the Company. This concentration of ownership may have
the  effect of delaying  or preventing a  change of control  of the Company. See
'Principal Stockholders.'

 
No Prior Trading Market; Possible Volatility of Stock Price
 

     Prior to the Offering, there  has been no public  market for shares of  the
Common  Stock, and there can be no  assurance that a regular trading market will
develop after the  Offering. The initial  public offering price  for the  Common
Stock   will  be  determined  by  negotiations   between  the  Company  and  the
Underwriters. See  'Underwriting.'  The  stock  market has  from  time  to  time
experienced  significant price and volume fluctuations  that may be unrelated to
the operating performance of particular companies. In addition, the market price
of  the  Common  Stock  may  prove  to  be  highly  volatile.  Announcements  of
technological  innovations, regulatory matters or new commercial products by the
Company or  its  competitors,  developments or  disputes  concerning  patent  or
proprietary  rights, publicity  regarding actual  or potential  clinical results
relating to  products  under development  by  the Company  or  its  competitors,
regulatory  developments in both the U.S.  and foreign countries, public concern
as to the  safety of pharmaceutical  products, and economic  and other  external
factors, as well as period-to-period fluctuations in financial results, may have
a significant impact on the market price of the Common Stock.

 
Forward Looking Statements
 

     This  Prospectus  contains  certain forward-looking  statements  within the
meaning of Section  27A of the  Securities Act of  1933 and Section  21E of  the
Securities  Exchange Act of 1934, as amended (the 'Exchange Act') concerning the
Company's operations, economic performance and financial conditions,  including,
in  particular,  the  likelihood  of the  Company's  success  in  developing and
bringing to market the products which it currently has under development.  These
statements  are  based upon  a  number of  assumptions  and estimates  which are
inherently subject to significant uncertainties and contingencies, many of which
are beyond the  control of  the Company  and reflect  future business  decisions
which  are  subject to  change. Some  of these  assumptions inevitably  will not
materialize, and unanticipated events will occur which will affect the Company's
results. Consequently, actual  results will vary  from the statements  contained
herein  and such  variance may  be, and is  likely to  be, material. Prospective
investors should not place undue reliance on this information.

Shares Eligible for Future Sale
 

     Of the  15,544,123 shares  of  Common Stock  to  be outstanding  after  the
Offering, no shares, other than the 3,500,000 shares of Common Stock sold in the
Offering,  will be immediately eligible for  resale in the public market without
restriction, after taking  into consideration the  effect of lock-up  agreements
entered  into by all officers, directors  and all other existing stockholders of
the Company (the  'Lock-up Agreements'). Beginning  180 days after  the date  of
this  Prospectus,  after taking  into consideration  the  effect of  the Lock-up
Agreements, approximately  11,840,358 additional  shares  of Common  Stock  will
become  eligible for resale in the public  market, subject as to certain of such
shares to  compliance with  applicable  provisions of  Rules  144 and  701.  See
'Shares Eligible for Future Sale.'

 

     Certain stockholders of the Company who own shares of the Company's capital
stock  prior to  the Offering are  entitled to certain  registration rights with
respect to  their  shares,  including  a  demand  registration  right  which  is
exercisable  after  270  days  from  the date  of  this  Prospectus  and certain
'piggyback'  registration  rights  which  are  exercisable  in  connection  with
registrations of shares initiated by the Company. Such rights are not applicable
to  the Offering. The Series B Preferred  Stock is convertible into an aggregate
of  100,000  shares  of  Common   Stock,  subject  to  customary   anti-dilution
adjustments,  at  any time  after  February 1,  1997.  Holders of  the  Series B
Preferred Stock have the right to require the Company to register the resale  of
the  Common Stock  that such  holders receive  upon conversion  of the  Series B
Preferred Stock  into  Common  Stock.  See  'Description  of  Capital  Stock  --
Registration Rights.'

 

     If  any such stockholders cause a large number  of shares to be sold in the
public market, such sales may have an adverse effect on the market price of  the
Common Stock and its ability to raise capital.

 
Dilution; Absence of Dividends
 

     Purchasers  of  shares  of  Common  Stock  offered  hereby  will experience
immediate and substantial  dilution of  $11.68 in  net tangible  book value  per
share,  assuming  an initial  public  offering price  of  $15.00 per  share. See
'Dilution.' The Company  has never declared  or paid any  cash dividends on  its
capital  stock. The  Company currently  intends to  retain earnings,  if any, to
support its growth strategy and does not anticipate paying cash dividends in the
foreseeable future.  Payment  of  future  dividends, if  any,  will  be  at  the
discretion of the Company's Board of Directors after taking into account various
factors, including the Company's financial condition, operating results, current
and anticipated cash needs and plans for expansion. See 'Dividend Policy.'

 
Effect of Anti-Takeover Provisions
 

     The  Company's Amended  and Restated Certificate  of Incorporation provides
for a classified Board of Directors  commencing with the 1996 annual meeting  of
stockholders  and that members of the Board of Directors may be removed only for
cause upon the affirmative vote of holders of at least a majority of the  shares
of  capital stock  of the  Company entitled to  vote. The  Company's Amended and
Restated Certificate  of  Incorporation requires  that  any action  required  or
permitted  to be taken by stockholders of the Company must be effected at a duly
called annual or special meeting of stockholders and may not be effected by  any
consent  in writing, and will require reasonable advance notice by a stockholder
of a proposal or director nomination  which such stockholder desires to  present
at   any  annual  or  special  meeting  of  stockholders.  Special  meetings  of
stockholders may be called only by the Chief Executive Officer or, if none,  the
President of the Company or by the Board of Directors. In addition, the Board of
Directors  has the authority, without further action by the stockholders, to fix
the rights and preferences of, and issue shares of, Preferred Stock. The Company
is subject  to the  anti-takeover  provisions of  Section  203 of  the  Delaware
General  Corporation  Law,  which  prohibits  the  Company  from  engaging  in a
'business combination' with an  'interested stockholder' for  a period of  three
years  after the date  of the transaction  in which the  person first becomes an
'interested stockholder,'  unless  the business  combination  is approved  in  a
prescribed  manner. The application of these provisions could have the effect of
delaying or  preventing  a change  of  control  of the  Company.  Certain  other
provisions  of the Company's  Amended and Restated  Certificate of Incorporation
could also  have the  effect of  delaying or  preventing changes  of control  or
management  of the Company, which could adversely affect the market price of the
Common Stock. See 'Description of Capital Stock.'

                                USE OF PROCEEDS
 
     The net proceeds to the  Company from the sale  of the 3,500,000 shares  of
Common  Stock offered  hereby are  estimated to  be approximately  $48.0 million
($55.3 million if the Underwriters' over-allotment option is exercised in full),
assuming an  initial  public  offering  price of  $15.00  per  share  and  after
deducting estimated underwriting discounts and commissions and offering expenses
payable by the Company.
 

     The  Company intends to use approximately $32.0 million of the net proceeds
of the Offering to fund anticipated research and product development  activities
and the planned establishment of the Company's direct sales force. The remaining
$16.0  million will be used for working  capital and for other general corporate
purposes including the  expansion of ongoing  and scheduled preclinical  studies
and  clinical trials or additional pre-clinical  studies and clinical trials, if
necessary, and the development of product line extensions and the initiation  of
development  programs  for  the  Company's next  generation  of  pain management
products for  which the  Company has  not allocated  any specific  amounts.  The
Company  believes it  is prudent  to raise the  additional capital  at this time
since product development costs are inherently uncertain and actual  development
costs  may exceed budgeted  amounts. A portion  of the net  proceeds also may be
used to acquire technology, licenses, or companies that complement the  business
of the Company, although currently there are no agreements or other arrangements
regarding  any such acquisitions by  the Company. The amount  and timing of such
expenditures will  depend on  a number  of factors,  including progress  of  the
Company's  research and  development programs, the  number and  breadth of these
programs, the progress of the  development and commercialization efforts of  the
Company,  the  ability  of  the  Company  to  establish  and  maintain strategic
alliances and  licensing  arrangements, competing  technological  and  marketing
developments, the costs involved in preparing, filing, prosecuting, maintaining,
and  enforcing  patent  claims and  other  proprietary rights,  progress  in the
regulatory process,  and  other  factors.  The Company  believes  that  the  net
proceeds  from the  Offering, together with  interest thereon  and the Company's
existing capital resources  will be sufficient  to fund its  operations for  the
research  and development of the products currently in clinical trials and other
working capital requirements for approximately  three years. Pending such  uses,
the  net  proceeds will  be  invested in  interest  bearing or  income producing
accounts.

 
                                DIVIDEND POLICY
 
     The Company has never  declared or paid any  cash dividends on its  capital
stock.  The Company currently intends to retain earnings, if any, to support its
growth strategy and does not anticipate paying cash dividends in the foreseeable
future. Payment of future dividends,  if any, will be  at the discretion of  the
Company's  Board  of  Directors  after  taking  into  account  various  factors,
including the  Company's financial  condition,  operating results,  current  and
anticipated cash needs and plans for expansion.

     The  net tangible book value  per share of the Common  Stock as of June 30,
1996 was $0.29 per share, after giving effect to the automatic conversion of all
outstanding Series A Preferred  Stock into an aggregate  of 5,872,247 shares  of
Common  Stock upon  consummation of the  Offering. 'Net tangible  book value per
share' represents  the total  tangible  assets less  total liabilities  and  the
liquidation preference of the Series B Preferred Stock, divided by the number of
shares  of  Common  Stock  outstanding  after  giving  effect  to  the automatic
conversion of Series A Preferred Stock into shares of Common Stock.

 

     Dilution per share represents  the excess of the  amount per share paid  by
purchasers  of Common Stock in the Offering  and the pro forma net tangible book
value per share assuming completion of the  Offering as of June 30, 1996, at  an
initial  public offering price of  $15.00 per share. After  giving effect to the
sale of 3,500,000 shares and the receipt of net proceeds of $48,025,000, the pro
forma net tangible book value per share  on June 30, 1996 would have been  $3.32
per share, which represents an immediate increase in the net tangible book value
of  $3.03 to existing  stockholders and an  immediate dilution of  $11.68 in net
tangible book value per  share to purchasers of  shares of Common Stock  offered
hereby, as illustrated by the following table:

warrants  at  an exercise  price of  $1.20  and 100,000  shares of  Common Stock
issuable upon the conversion of the  Series B Preferred Stock after February  1,
1997.  The issuance of  any such shares  will result in  further dilution to new
investors.

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

     Certain information set forth herein contains forward-looking statements as
such  term is defined in  Section 27A of the Securities  Act of 1933 and Section
21E of the  Exchange Act. Certain  factors discussed herein  could cause  actual
results  to differ materially from those  in the forward-looking statements. See
'Risk Factors -- Forward Looking Statements.'

 
OVERVIEW
 
     Algos, a development stage company, is engaged primarily in the development
and  commercialization  of  proprietary   pharmaceutical  products.  Since   its
formation  in January 1992, the Company has  devoted a substantial amount of its
efforts to licensing technology, recruiting key management and staff, developing
products, filing patents and other regulatory applications and raising  capital.
To  date, the Company has  earned no revenue from  its planned principal line of
business.
 
     The Company has incurred  losses since its inception  and expects to  incur
significant operating losses in the future. The Company expects that its product
development expenses will increase significantly during 1996 and in future years
as the drugs that the Company currently has under development move into advanced
clinical  trials  and as  additional drugs  are  considered for  development. In
addition,  the  Company   expects  that  its   personnel  costs  will   increase
significantly in the future, primarily as a result of the planned development of
a direct sales force.
 
RESULTS OF OPERATIONS
 

SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1995

 

Revenue

 

     In  the 1996 period, the Company  recognized $1,500,000 of license revenue.
This amount represents the  initial payment of $2,000,000  due under the  McNeil
License  Agreement and received  in July 1996, less  $500,000 which is currently
restricted for the funding of future development costs.

 
Research and Development
 

     In the 1996 period, research  and development expenses increased  $202,801,
to $1,003,585 from $800,784 in 1995. The 1996 period included increased expenses
related   to  the  Company's   clinical  trials,  including   fees  to  clinical
investigators which increased approximately $243,000. Increased compensation  to
employees  and  consultants  was  offset  by  reduced  spending  on pre-clinical
studies.

 
General and Administrative Expenses
 

     In  the  1996  period,   general  and  administrative  expenses   increased
$1,231,726  to $1,628,184 from $396,458 in  1995. The increase was due primarily
to a charge of $915,000 in the 1996 period relating to the issuance of Series  B
Preferred  Stock in connection  with an amendment to  the license agreement with
The Medical  College  of  Virginia and  amortization  of  unearned  compensation
expense of approximately $189,000 in connection with the grant of stock options.
Higher  professional  fees and  compensation  expenses also  contributed  to the
increase.

 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO THE YEAR ENDED DECEMBER 31, 1994
 
Research and Development
 

     In  1995,  research  and   development  expenses  increased  $961,229,   to
$1,614,943  from $653,714 in  1994. This increase  was primarily attributable to
the Company's pre-clinical studies  in the field of  NMDA antagonists. In  1995,
direct  costs  associated with  pre-clinical  studies and  clinical  trials were
approximately $542,000 and  formulation development, drug  supplies and  related
analytical   services  totaled  approximately   $265,000.  Compensation  expense
increased as a result of the addition of employees and consultants. Spending  on
other programs also contributed to the increase in 1995

expenditures.  Expenses in 1994  consisted primarily of  employee and consultant
compensation as  the  Company  established  its  research  management  team  and
initiated sponsored research programs at three universities.
 
General and Administrative Expenses
 
     In  1995,  general  and  administrative  expenses  increased  $136,821,  to
$760,040 from  $623,219 in  1994. This  increase was  primarily attributable  to
additional  employee compensation and  related taxes and  benefits. In addition,
general office expenses  such as rent,  utilities, and supplies  increased as  a
result of increased business activities and employment.
 
Interest Income
 

     In  1995, interest income  increased $99,301, to  $252,548 from $153,247 in
1994 as  a result  of the  investment  of proceeds  from the  Company's  private
placement of Series A Preferred Stock, which was completed in August 1994.

Revenue
 
     In  1993,  the Company  earned $214,584  for performing  certain consulting
services unrelated to  its planned  principal operations.  Effective January  1,
1994,  the consulting contract was assigned  to another corporation. The Company
will not earn any revenue or incur any expenses in the future in connection with
that consulting contract.
 
Research and Development
 
     In 1994, research and development expenses increased $613,714, to  $653,714
from  $40,000  in  1993.  This  increase  was  principally  attributable  to the
Company's establishment  of  its  research management  team  and  initiation  of
sponsored research programs at three universities.
 
General and Administrative Expenses
 
     In  1994,  general  and  administrative  expenses  increased  $187,562,  to
$623,219  from  $435,657  in  1993.   This  increase  was  due  principally   to
professional  fees related to patent  investigations and applications, sponsored
research programs and other general corporate expenses.
 
Interest Income
 

     Interest income  of  $153,247  in  1994  was  derived  primarily  from  the
investment  of proceeds from the private  placement of Series A Preferred Stock,
which was completed in August 1994. The Company earned interest income of $4,433
in 1993 from the investment of capital contributions by the Company's founders.

 
LIQUIDITY AND CAPITAL RESOURCES
 
General
 

     In 1995, 1994,  and 1993,  spending for the  Company's product  development
efforts  and related activities resulted in net cash outflows from operations of
$1,929,321, $991,928 and  $289,277, respectively. Accumulated  cash balances  at
December  31,  1992, which  resulted from  the Company's  initial capitalization
together with additional investments by the Company's founders, were  sufficient
to  provide operating funds into 1994. In 1994, in order to initiate its planned
product development  programs,  the Company  sold  700,000 shares  of  Series  A
Preferred Stock in a private placement, resulting in net proceeds of $6,609,015.
A  portion of these funds were used to fund the Company's development efforts in
1995 and the first six  months of 1996. At June  30, 1996, the Company had  cash

 
                                       17
 
<PAGE>
<PAGE>

and  cash equivalents  of $2,504,603 and  current liabilities  of $1,254,174. In
addition, the Company received $2.0 million from McNeil on July 5, 1996 pursuant
to the McNeil  License Agreement,  of which $500,000  is committed  to fund  the
Company's  portion  of development  costs  under the  McNeil  License Agreement.
Without the proceeds of the Offering, the Company believes that current cash and
cash equivalents are  sufficient to fund  a reduced level  of operations for  at
least the next 12 months.

 

     The  Company expects to invest substantial  funds in the development of its
products and  to continue  to generate  significant losses  for the  foreseeable
future.  Its funding requirements will depend  on a number of factors, including
the results  of  the Company's  development  efforts,  the timing  and  cost  of
obtaining   required   regulatory  approvals,   the  development   of  competing
technologies,  the  amount  of  resources  required  for  the  establishment  of
marketing  and distribution  capabilities, the  execution of  licensing or other
collaborative research agreements on  terms acceptable to  the Company, and  the
cost  of prosecuting and  defending patents. The  Company currently expects that
the proceeds from the Offering will be sufficient to fund its operations for the
development of products currently in  clinical trials, based upon the  Company's
presently  anticipated schedule  of clinical  trials, and  other working capital
requirements for approximately three years.  If, however, additional trials  are
deemed  to be  necessary, the Company  may require additional  funds to complete
such trials.  Accordingly, in  the  event that  the  proceeds of  the  Offering,
revenue  and income  from successful  product introductions  or other internally
generated funds are  insufficient for  such efforts,  the Company  will need  to
raise  additional funds by incurring debt,  issuing additional equity or through
collaborative or license arrangements. See 'Risk Factors -- Need for  Additional
Funds.'

 
Net Operating Loss Carryforwards
 

     At  December 31, 1995  and June 30,  1996, the Company  had accumulated net
operating  loss  carryforwards  of  approximately  $2,900,000  and   $2,100,000,
respectively,  which expire in 2009 and 2010  and are available to reduce future
taxable income  recognized  in the  carryforward  period,  if any.  Due  to  the
uncertainty  of future taxable  income, the Company  has established a valuation
allowance for these carryforwards and has not recognized their potential benefit
on a current basis. The future utilization of these carryforwards may be limited
by Section  382 of  the Internal  Revenue  Code related  to changes  in  Company
ownership.

 
Other
 
     Generally,  the  Company's  results  of  operations  are  not significantly
affected by seasonal factors and the Company does not believe that inflation has
had or is likely to have a significant impact on its business.
 
     In October 1995, the Financial Accounting Standards Board issued  Statement
of  Financial Accounting  Standards ('SFAS')  No. 123  -- 'Accounting  for Stock
Based Compensation,'  which  generally  requires disclosure  of  the  impact  on
earnings of stock based employee compensation arrangements. The Company plans to
adopt the disclosure requirements of SFAS No. 123 effective January 1, 1996.

COMPANY OVERVIEW
 

     Algos  is  a leader  in  developing a  new  generation of  proprietary pain
management products.  The  Company  develops  its  proprietary  pain  management
products   by  combining  existing  analgesic  or  anesthetic  drugs  with  NMDA
antagonist drugs that have  been approved for human  use in other  applications.
Independent  research and the Company's pre-clinical studies and clinical trials
conducted to  date have  shown  that the  Company's products  may  significantly
improve  pain  relief over  currently  available analgesics,  including narcotic
drugs such as  morphine, hydrocodone and  oxycodone and non-narcotic  analgesics
such  as acetaminophen (e.g. Tylenol'r'), ibuprofen (e.g. Advil'r') and naproxen
(e.g. Aleve'r'). The Company is also developing a local anesthetic product  that
has  the potential  to provide  greater anesthetic  effect with  longer and more
controlled  duration  than  existing  products.  The  Company's  analgesic   and
anesthetic  products will target markets with combined 1995 U.S. sales estimated
at $6.4  billion.  In  addition,  the  Company  is  using  its  NMDA  antagonist
technology to develop products to treat urge urinary incontinence and opiate and
cocaine addiction.

 

     The  Company believes that  its analgesic and  anesthetic products have the
potential for more rapid market introduction  than many other new drugs  because
(i) the Company's products combine existing drugs whose separate safety profiles
are  known  and established  and  (ii) clinical  trials  for new  analgesics and
anesthetics historically have  achieved statistically  significant results  with
fewer  patients than  may be  required for  many other  drugs. As  a result, the
Company currently anticipates that it  will file its first  NDA with the FDA  in
1997.

 

     The  Company has ten products that have reached Phase II clinical trials or
are scheduled for Phase II or Phase III clinical trials in 1996. The Company has
completed or is currently  conducting eleven clinical  trials and has  scheduled
additional  clinical trials  to commence  in 1996.  A pivotal  Phase II clinical
efficacy trial has been completed with MorphiDex'tm' demonstrating statistically
significant superior pain relief over morphine.

 

     The Company's products that  have reached Phase II  clinical trials or  are
scheduled for Phase II or Phase III clinical trials consist of:

 
      (i) four   narcotic   analgesic/NMDA   antagonist   combination  products:
          MorphiDex'tm', expected to  be used  primarily to  treat cancer  pain,
          HydrocoDex  SR'tm'  and  HydrocoDex  Plus'tm',  expected  to  be  used
          primarily to  treat  moderate  to  moderately  severe  post-operative,
          musculoskeletal and trauma-related pain, and OxycoDex'tm', expected to
          be   used   primarily   to  treat   moderate   to   moderately  severe
          post-operative pain;
 
      (ii) two OTC analgesic/NMDA antagonist combination products: a combination
           product of an NMDA antagonist with acetaminophen, the largest selling
           OTC analgesic, and a combination  product of an NMDA antagonist  with
           ibuprofen, the largest selling OTC NSAID;
 

     (iii) one  injectable local anesthetic/NMDA combination product intended to
           provide greater  anesthetic effect  with longer  and more  controlled
           duration  for use in dental procedures and in-patient and out-patient
           surgeries;

 
      (iv) one product that uses an NMDA antagonist intended as a treatment  for
           urge  urinary incontinence,  a condition which  afflicts an estimated
           five million people in the U.S.; and
 

      (v) two products intended as treatments for opiate and cocaine  addiction,
          which the Company expects to develop in collaboration with NIDA, NIH.

 
COMPANY STRATEGY
 
     The Company's strategic goal is to establish a leading position in the pain
management  pharmaceutical market. The  Company intends to  achieve this goal by
implementing the following strategy:
 
     Introducing  superior  proprietary  products.  Based  on  the  results   of
independent  research,  pre-clinical studies  and  initial clinical  trials, the
Company  believes   its   products   will   provide   superior   efficacy   over
 
                                       19
 
<PAGE>
<PAGE>
currently  available narcotic, non-narcotic and anesthetic products. The Company
intends to build significant market share in both the OTC and prescription  pain
management markets.
 
     Minimizing  development time, cost and risk. The Company attempts to reduce
drug development time  and cost at  each stage of  the development process.  The
Company  believes that it  will be able  to develop its  initial products faster
than other types of new drugs because all of the Company's initial products  are
combinations  of, or  forms of,  existing approved  drugs. For  its pre-clinical
studies, the  Company is  able to  save time  and expense  by drawing  upon  the
experience  of many  highly regarded  researchers in  the pain  management field
through its  collaborations  with established  academic  research  institutions.
Similarly,  for its clinical  trials, the Company  collaborates with researchers
who have the experience and the  facilities to design timely and  cost-effective
trials.  In addition,  the Company  believes that  new analgesic  and anesthetic
products have the potential for more  rapid market introduction than many  other
types of drugs.
 

     Leveraging    its   proprietary   technology    across   multiple   product
opportunities. Through  extensive pre-clinical  research, Algos  has  identified
multiple potential products using NMDA antagonist technology. As a result, Algos
has  developed  ten pharmaceutical  products that  have  progressed to  Phase II
clinical trials or are scheduled  for Phase II or  Phase III clinical trials  in
1996.

 
     Outsourcing  to  efficiently  deploy  resources.  The  Company  intends  to
continue to contract the  resources of well-recognized commercial  organizations
to  perform pre-clinical studies, clinical trials and pharmaceutical development
on behalf of  the Company.  In addition, the  Company intends  to outsource  its
manufacturing functions to third party suppliers.
 

     Maximizing market penetration and margin potential through a combination of
Company direct sales and strategic alliances. In market segments with relatively
concentrated  distribution channels,  such as  prescription analgesics  that are
sold   to   individual   hospitals,   health   maintenance   organizations   and
pharmaceutical  buyer  groups,  the Company  plans  to maximize  its  margins by
marketing these products through a direct  sales force. In market segments  that
will  require large  or specialized  sales capabilities,  such as  OTC analgesic
products  and  certain  foreign  countries,  the  Company  will  seek  strategic
alliances  with  leading  pharmaceutical companies.  The  Company  believes such
alliances enhance  its ability  to  identify new  products  as well  as  quickly
develop and commercialize such products.

 
MARKET OVERVIEW
 
     The  Company  is  developing products  that  will target  the  narcotic and
non-narcotic analgesic markets,  the local anesthetic  market, the urge  urinary
incontinence  market  and  the  market  for  treatment  of  opiate  and  cocaine
addiction.
 
The Analgesic Market
 

     The Company's analgesic  products will  target markets  with combined  1995
U.S.  sales estimated at  $6.4 billion. The Company  believes that the analgesic
market presents attractive opportunities based upon the following factors:  high
growth  rates partially attributable  to the rapidly  growing population segment
aged 65  and  older;  increasing  recognition of  the  therapeutic  benefits  of
effective  pain  treatment including  reductions in  healing and  recovery time;
generally concentrated  distribution channels  that permit  more  cost-effective
selling  and marketing; lack of recent  product innovation which has resulted in
market segments  comprised  largely of  older  off-patent drugs;  higher  profit
margins   from  branded  proprietary  products;  and  the  potential  for  rapid
acceptance of  new pain  management pharmaceuticals  by members  of the  medical
profession.

The Anesthetic Market
 

     In 1995, the injectable local anesthetic  market in the U.S. was  estimated
at  $164  million.  The market  for  local  anesthetics is  believed  to present
attractive opportunities  for a  controlled  duration product  because  existing
local  anesthetics have limited  and less controllable  duration which restricts
their use in surgery. The Company believes that a controlled, extended  duration
local  anesthetic,  if  successfully  developed,  would  have  the  potential to
significantly expand this market segment.

 
The Urge Urinary Incontinence Market
 

     An estimated  five million  people in  the U.S.  suffer from  urge  urinary
incontinence.  While sales of  urge urinary incontinence drugs  in the U.S. were
estimated at $84 million in 1995, U.S. sales of incontinence supplies (including
adult protective undergarments) were significantly  higher at an estimated  $1.1
billion in 1994. This was due, in part, to a lack of satisfactory pharmaceutical
treatments.  The Company believes  that if satisfactory  drugs for treating urge
urinary  incontinence  were  introduced,  the  market  size  for  urge   urinary
incontinence drugs could grow considerably.

 
The Drug Abuse Treatment Market
 
     NIDA  estimates that  there are  two million  opiate addicts  in the United
States and 1.5  to 2 million  cocaine abusers. The  Company believes that  these
opiate  addict and cocaine abuser populations represent a large potential market
for effective pharmaceutical treatment.

NARCOTIC ANALGESICS
 
     Narcotic analgesic drugs remain  the most common  and useful treatment  for
moderate  to  severe pain  in  both acute  and  chronic conditions.  These drugs
consist of naturally occurring opiates (e.g. morphine), opiate derivatives (e.g.
codeine, hydrocodone, oxycodone), and synthetic opiates (e.g. methadone). One of
the most  significant drawbacks  to  these drugs  is  the development  of  rapid
tolerance and physical dependence. Tolerance refers to the condition under which
a  drug dose  that was initially  effective in producing  analgesia becomes less
effective with repeated administrations. Therefore, to alleviate the same  level
of  pain, the drug dose  has to be increased  over time. However, increasing the
drug dose  may produce  an increase  in  unwanted side  effects such  as  mental
clouding,  nausea and constipation and may  also increase the potential for drug
dependence.
 
     Pre-clinical studies of  the Company's  narcotic analgesic/NMDA  antagonist
combination products indicated superior first-dose analgesic effects as compared
to equivalent dosage levels of the narcotic analgesic alone and greater efficacy
when   administered   over   periods  during   which   the   narcotic  analgesic
 
                                       22
 
<PAGE>
<PAGE>
administered alone  became less  effective. The  Company believes  that its  new
products,  if proven effective in humans in producing superior analgesic effects
and reducing tolerance and side effects, could replace a significant portion  of
the narcotic analgesics currently in use for acute and chronic pain and could be
used  in  chronic  pain  cases  where  physicians  have  been  reluctant  to use
narcotics.
 
MorphiDex'tm'
 
     MorphiDex'tm', the  Company's  most developmentally  advanced  product,  is
designed  to  treat moderate  to  severe pain  and  will be  used  primarily for
treating cancer pain. MorphiDex'tm' is the trade name for the Company's patented
morphine and  dextromethorphan  combination product.  The  addition of  an  NMDA
antagonist  to morphine is intended  to increase analgesic effectiveness, reduce
the  development  of  tolerance  to  morphine  and  reduce  the  development  of
hyperalgesia in cases of chronic administration.
 
     The  Company expects to use MorphiDex'tm' to target the market for morphine
products. In  1995, U.S.  sales  of morphine  products were  approximately  $247
million  and  non-U.S. sales  were approximately  $500  million. This  market is
believed to be growing at  an estimated rate of 18%  per year, which is  largely
attributable  to the rapidly growing population segment aged 65 and older in the
United States, Europe and Japan.
 
     The  Company's  research  and   development  activities  with  respect   to
MorphiDex'tm' include:
 
      (i) pre-clinical   pharmacology  studies  which   indicate  that  morphine
          tolerance may be  significantly reduced by  co-administration with  an
          NMDA antagonist;
 
      (ii) pre-clinical   toxicology  and  drug  safety  studies  comparing  the
           combination of dextromethorphan and morphine to the individual drugs;
 

     (iii) one completed,  double  blind Phase  I/II  clinical trial  to  assess
           safety  and  abuse  liability  which  indicates  product  safety  and
           possible lower abuse potential;

 

      (iv) one completed, double blind Phase I/II clinical trial in chronic pain
           patients which indicates that a  combination of morphine or  morphine
           equivalents  together with  an NMDA  antagonist is  safe at projected
           therapeutic dose  levels  and that  such  a combination  may  provide
           superior pain relief over morphine; and

 

      (v) one completed pivotal Phase II clinical efficacy trial in oral surgery
          patients  which  indicates  statistically  significant  superior  pain
          relief with MorphiDex'tm' over morphine alone.

 

     In addition, four additional clinical  trials are currently underway  which
the Company expects will lead to an NDA filing in the second half of 1997.

 
HydrocoDex'tm' SR and HydrocoDex Plus'tm'
 

     Hydrocodone  is a narcotic  primarily used to  treat moderate to moderately
severe post-operative, musculoskeletal  and trauma-related  pain. The  analgesic
products  containing  hydrocodone that  are sold  commercially  in the  U.S. are
combination products  containing acetaminophen.  In 1995,  the market  for  such
products  in the  U.S. was approximately  $315 million with  an estimated growth
rate of 15% per year.

 
     HydrocoDex SR'tm' is  the trade  name for the  Company's sustained  release
product  that combines hydrocodone and  dextromethorphan. Currently there are no
sustained release hydrocodone  products on  the market because  the dosage  size
required  to achieve a sustained effect  when combined with acetaminophen is too
large for  practical application.  The  Company expects  that, if  approved  and
successfully  brought to market, HydrocoDex  SR'tm' will provide physicians with
the ability to  prescribe an effective  sustained release hydrocodone  analgesic
for the first time.
 
     HydrocoDex  Plus'tm' is the trade name  for the Company's immediate release
product that  combines  hydrocodone,  dextromethorphan  and  acetaminophen.  The
Company  believes that  HydrocoDex Plus'tm' may  broaden the  current market for
hydrocodone/acetaminophen  combination   products  because   equal  or   greater
therapeutic  effect  may  be  achieved  by  administering  lower  doses  of  the
hydrocodone component of  the product,  thereby potentially  creating a  product
with a lower abuse potential.
 
                                       23
 
<PAGE>
<PAGE>
     The  Company is planning to  begin a Phase II  clinical trial in the second
half of 1996 intended to show that the addition of an NMDA antagonist  increases
the  efficacy of  products containing  hydrocodone. The  results of pre-clinical
studies for these products have been favorable.
 
OxycoDex'tm'
 

     Oxycodone is an opiate narcotic that, in combination with acetaminophen  or
aspirin,  forms the basis for a group of products which are broadly used for the
treatment of moderate  to moderately  severe post-operative and  other types  of
pain. In 1995, the U.S. market for such products was estimated at $73 million.

 
     The  Company is currently in the process of developing an immediate release
combination product consisting of oxycodone, acetaminophen and dextromethorphan.
Pre-clinical studies have  indicated that  an NMDA antagonist  may increase  the
efficacy  of oxycodone. In April 1996, the National Institute of Dental Research
('NIDR') commenced a clinical  trial comparing the  efficacy of oxycodone  alone
and  in  combination with  an NMDA  antagonist.  Additional clinical  trials are
scheduled to be conducted in 1996.
 
NON-NARCOTIC ANALGESICS
 

     The  Company   has  two   non-narcotic   analgesics  in   development:   an
ibuprofen/NMDA   antagonist  combination   product  and   an  acetaminophen/NMDA
antagonist combination product. In 1995, the OTC NSAID market in the U.S.  which
included  ibuprofen totaled an estimated $853 million. The total U.S. OTC market
for acetaminophen  was  estimated at  $1.2  billion. The  Company  has  licensed
certain   NSAID/NMDA   antagonist   products  (including   ibuprofen)   and  its
acetaminophen/NMDA antagonist  products  to  McNeil.  See  '  --  Corporate  and
Government Collaborations.'

 
Ibuprofen/NMDA Antagonist Combination
 
     Pre-clinical  studies have indicated that the analgesic efficacy of several
NSAIDs, such as ibuprofen and naproxen,  may be increased when combined with  an
NMDA  antagonist.  The  Company  believes  that  an  OTC  product  based  upon a
combination of existing dosage levels of an NSAID with an NMDA antagonist  would
offer  analgesic efficacy that is superior  to existing OTC analgesics and could
have the potential to  achieve rapid market acceptance.  In addition, at  dosage
levels  where the NSAID  indicated no analgesic effect  by itself, a significant
analgesic effect  was indicated  by the  addition of  an NMDA  antagonist. As  a
result,  an NSAID/NMDA antagonist combination product  may also be formulated to
give an equivalent  analgesic effect while  lowering the NSAID  dosage and  thus
potentially  reducing certain  dosage related  side effects  of NSAIDs,  such as
gastrointestinal bleeding and ulcers.
 

     An initial Phase II clinical trial has indicated that an NSAID  (ibuprofen)
in  combination with an  NMDA antagonist may have  an increased analgesic effect
when compared to  the NSAID  alone in  dental surgery  patients who  experienced
greater  surgical trauma (i.e. patients who had surgery which lasted longer than
30 minutes). The study also indicated that for dental patients in certain  lower
trauma categories (i.e. patients whose surgery lasted less than 30 minutes) both
ibuprofen  alone  and ibuprofen  in combination  with an  NMDA antagonist  had a
significantly better  analgesic  effect when  compared  to a  placebo  and  that
ibuprofen  alone and ibuprofen in combination  with an NMDA antagonist were both
similarly effective  in  relieving  the patient's  pain.  Although  the  Company
believes  that  these results  are encouraging,  additional clinical  trials are
necessary in order to submit an NDA to the FDA.

 
Acetaminophen/NMDA Antagonist Combination
 

     The Company has sponsored pre-clinical studies to evaluate acetaminophen in
combination with NMDA antagonists. The  results indicate that combining an  NMDA
antagonist  with acetaminophen may increase the  efficacy of acetaminophen. In a
placebo-controlled Phase II clinical trial conducted by NIDR, patients taking  a
scheduled regimen of an NMDA antagonist (dextromethorphan) before and after oral
surgery  required substantially less acetaminophen  after the surgery to relieve
pain.

ANESTHETICS (LIDOCAINE/NMDA ANTAGONIST COMBINATION)

 

Injectable Anesthetic

 

     The injectable local anesthetic market was estimated at $164 million in the
U.S. in  1995.  Sales consist  primarily  of older  off-patent  drugs.  Although
research  indicates that the administration  of analgesics preceding surgery may
improve  surgical  outcomes,  the   limited  duration  of  existing   injectable
anesthetics limits their use in surgery.

 

     The  Company, in collaboration  with Brigham and  Women's Hospital, Harvard
Medical  School,  is  conducting  research   into  the  potentiation  of   local
anesthetics  by NMDA antagonists.  Pre-clinical studies have  indicated that the
NMDA antagonist,  dextromethorphan,  may  increase the  depth  and  duration  of
anesthesia of lidocaine. With the current emphasis on preemptive analgesia, same
day  surgery  and shorter  hospital stays,  the Company  believes that  a longer
duration anesthetic may provide greater patient comfort when post surgical  pain
is most severe. A Phase I/II clinical trial is planned for late 1996.

 

Anti-Migraine

 

     Reported results of an independently conducted clinical trial indicate that
intra-nasal  lidocaine  provides rapid  relief  of migraine  headache,  but that
relapse is common. Since  the NMDA antagonist  dextromethorphan may enhance  the
efficacy  of lidocaine and is also  effective in inhibiting neuropathic pain, an
intra-nasal  lidocaine/dextromethorphan  combination  product  may  be  a   more
effective  anti-migraine treatment.  Pre-clinical studies  are planned  for late
1996.

 
OTHERS
 
Urge Urinary Incontinence Treatment
 

     An estimated  five million  people in  the U.S.  suffer from  urge  urinary
incontinence.  While sales of  urge urinary incontinence drugs  in the U.S. were
estimated at $84 million in 1995, U.S. sales of incontinence supplies (including
adult protective undergarments) were an estimated $1.1 billion in 1994. This was
due, in  part,  to a  lack  of  satisfactory urge  urinary  incontinence  drugs.
Existing  urge urinary incontinence drugs generally have unpleasant side effects
and low levels of efficacy. The Company believes that if satisfactory drugs  for
treating  urge urinary incontinence are introduced,  consumer demand for an urge
urinary incontinence drug could increase considerably.

 

     Company-sponsored pre-clinical studies have indicated that NMDA antagonists
may block the bladder micturition reflex. A Phase II clinical trial is currently
being conducted at  the Stanford University  School of Medicine  to evaluate  an
NMDA  antagonist in urge  incontinent patients. If  successful, these agents may
offer a novel, safe and effective treatment for urge urinary incontinence.

 
Opiate and Cocaine Addiction Treatment Drugs
 

     NIDA estimates that  there are  two million  opiate addicts  in the  United
States  and 1.5 to  2 million cocaine  abusers. These opiate  addict and cocaine
abuser populations represent  a large potential  market for effective  treatment
drugs.  The Company is developing an  NMDA antagonist-based product as an opiate
addiction treatment  drug.  NIDA  is  planning a  Phase  II  clinical  study  in
collaboration  with the Company to test this opiate addiction treatment drug. In
addition,  the  Company  is  developing  a  cocaine  addiction  treatment  drug.
Pre-clinical studies have indicated that NMDA antagonists may have potential for
the treatment of dependence on opiate narcotics and cocaine abuse.

 
SCIENTIFIC OVERVIEW
 

     A  key element of the Company's technology  is the use of NMDA antagonists,
which block the  NMDA receptor.  NMDA receptors are  believed to  be present  in
nerve  cells in  the brain  and spinal cord.  There is  increasing evidence that
there may also be peripheral NMDA receptors.

 
     The important  role  of the  NMDA  receptor  in pain  response  has  become
recognized  among scientists  and clinicians.  Research indicates  that the NMDA
receptor plays a role in neuropathic pain,
 
                                       25
 
<PAGE>
<PAGE>
development  of  tolerance  to  and  dependence  on  narcotic  analgesics,   and
development  of hyperalgesia due to  chronic administration of opiate narcotics.
According to current scientific theory, activation of this receptor results in a
cascade of  intracellular  events beginning  with  the influx  of  extracellular
calcium.  This influx  of calcium  results in  activation of  the enzyme protein
kinase C and its subsequent translocation from cytosol to the membrane.  Through
protein   phosphorylation,  enduring   changes  then   occur  in   the  membrane
constituents including  receptors. This  cascade of  events beginning  with  the
activation  of the  NMDA receptor has  been implicated  in numerous neuroplastic
phenomena such as post-tetanic potentiation  resulting in sensitized and  overly
active  nerve cells and consequently may cause spontaneous pain and/or increased
sensitivity to pain.
 
     It is believed that  narcotic analgesics reduce pain  by binding to  opiate
receptors  located on  nerve cells  in the brain  and spinal  cord. Although the
initial effect of this binding is to  inhibit the nerve cell and thereby  reduce
pain, opiate receptor activation is also believed to stimulate the NMDA receptor
leading  to  the cascade  of events  described in  the previous  paragraph. Many
researchers believe  that  increased  NMDA receptor  activation  represents  the
underlying  cellular mechanism of opiate  tolerance and dependence. Pre-clinical
studies indicate that by blocking the NMDA receptor, tolerance to and dependence
on opiates may  be reduced and  the development of  hyperalgesia prevented.  The
involvement of the NMDA receptor in dependence is also the basis for development
of NMDA antagonists to treat drug addiction.
 

CORPORATE AND GOVERNMENT COLLABORATIONS

 

     In  June 1996, the  Company entered into the  McNeil License Agreement with
McNeil, an affiliate of Johnson & Johnson, pursuant to which the Company granted
McNeil the exclusive right to develop acetaminophen/NMDA antagonist  combination
products  and certain NSAID/NMDA antagonist  combination products (ibuprofen and
certain other NSAIDs approved for OTC use) for the treatment of pain. The McNeil
License Agreement provides  for an  initial payment  of $2.0  million by  McNeil
(funded  on July 5, 1996)  to the Company and additional  payments of up to $8.0
million by McNeil upon the achievement of certain milestones generally  relating
to  product development and  patent issuances. In addition,  the Company will be
entitled to receive royalty payments from  McNeil based upon net product  sales.
McNeil  will bear all  the costs of  developing products it  selects, except for
approximately $500,000 to be  borne by the Company.  McNeil will be required  to
pay  minimum  royalties  commencing  a  certain  time  after  execution  of  the
agreement, provided that certain  conditions have been met,  even if McNeil  has
not  commenced marketing  of an acetaminophen  product or an  NSAID product. The
McNeil License  Agreement extends  until  the later  of  the expiration  of  the
Company's patent rights or ten years, provided that the McNeil License Agreement
is  terminable: (i)  by either party  in the event  of a material  breach by the
other party upon 90 days' notice or  upon certain events of bankruptcy; (ii)  by
McNeil, at any time after one year from the effective date of the agreement; and
(iii)  by the Company under  certain circumstances. Under certain circumstances,
the  McNeil  License   Agreement  could   terminate  with   respect  to   either
acetaminophen  or NSAID products  without terminating with  respect to the other
category. In the event of a termination  by McNeil, McNeil must pay all  royalty
payments  and milestone  payments due  through the  date of  termination and the
technology licensed by McNeil reverts to the Company. In such event, the Company
retains the rights  to the results  of the  two clinical studies  funded by  the
Company,  and McNeil retains the  rights to the results  of the clinical studies
funded  by  McNeil  during  the  term  of  the  McNeil  License  Agreement.  See
' -- Patents, Trade Secrets and Licenses -- Licenses.'

 

     In  June 1996, the Company entered into  a letter of intent with NIDA, NIH,
pending formal approval of a CRADA to conduct joint research on a methadone/NMDA
antagonist combination drug as a potential treatment for opiate addition.

 
ACADEMIC AND RESEARCH COLLABORATIONS
 
Virginia Commonwealth University, The Medical College of Virginia
 
     In 1994, the Company entered  into a collaborative research agreement  with
The  Medical College of Virginia with the option for subsequent annual renewals.
Under the terms of this agreement, The

(iii) treatment of neuropathic pain, under the direction of David J. Mayer, Ph.D
and  Donald  D.  Price,  Ph.D., Professors,  Department  of  Anesthesiology, The
Medical College of Virginia.
 
Brigham and Women's Hospital
 
     In 1995, the  Company entered into  a research agreement  with Brigham  and
Women's  Hospital, Inc., a  teaching affiliate of  Harvard Medical School. Under
the terms of this agreement, Brigham and Women's Hospital performs  pre-clinical
research  exclusively for the  Company in the field  of long lasting anesthetics
under the  direction  of Gary  R.  Strichartz, Ph.D.,  Professor  of  Anesthesia
(Pharmacology).  The research is designed to measure certain characteristics and
effects of  various  anesthetic/NMDA  antagonist  combinations  covered  by  the
Company's existing or pending patents.
 
Stanford University
 

     The  Company has entered into a series of research agreements with Stanford
University. Under  the  direction of  Christos  E. Constantinou,  Ph.D.  of  the
Stanford  University School of Medicine, certain NMDA antagonists were tested in
pre-clinical studies to assess their potential for use in the treatment of  urge
urinary  incontinence. The  studies were  conducted with  products that  are the
subject of  one  of the  Company's  pending patent  applications.  In  addition,
Christopher Payne, M.D. is currently conducting a clinical trial to further test
the  potential  of  such NMDA  antagonists  for  the treatment  of  urge urinary
incontinence.

 
CLINICAL TRIAL COLLABORATIONS
 
     Clinical trials  with  several  major  research  institutions  and  medical
centers have commenced, and several others are scheduled for commencement in the
near future. The institutions with which the Company collaborates include:
    
     Johns Hopkins Bayview Medical Center, Baltimore, Maryland
     Memorial Sloan-Kettering Cancer Center, New York City, New York
     Emory University Hospital Medical Center, Atlanta, Georgia
     Stanford University School of Medicine, Palo Alto, California
     University of Pennsylvania, Philadelphia, Department of Veterans Affairs
     Medical Center, Philadelphia, Pennsylvania
     Royal North Shore Hospital, University of Sydney, Australia
     National Institute of Dental Research, National Institutes of Health,
     Bethesda, Maryland
     Rivers Center Research Corporation, Columbia, Maryland
     SCIREX Corporation, Austin, Texas
     
     The Company generally conducts clinical studies directly with the principal
investigators  and also by  the use of  Contract Research Organizations ('CROs')
that provide additional manpower  as required to  manage several study  programs
simultaneously.  The  Company's  management  is  experienced  at  selecting  and
managing CROs for conducting clinical studies.
 
TECHNICAL DEVELOPMENT AND PRODUCTION
 

     The Company  generally  seeks to  contract  third parties  for  formulation
development,  manufacture  of clinical  trial materials  and scale-up  work. The
Company generally  selects third  party contractors  that it  believes have  the
capability  to commercially manufacture the products.  The key advantage to this
approach is that the  third party contractor  which performed the  developmental
work  will  have the  equipment,  operational parameters  and  validated testing
procedures already  in place  for the  commercial manufacture  of the  Company's
products.  The Algos  management team is  experienced in  selecting and managing
activities at third party contract companies. By selecting qualified third party
contractors or

 
                                       27
 
<PAGE>
<PAGE>

by choosing development partners that provide full scale contract  manufacturing
services,  the Company believes it will be  able to shorten development time and
scale-up to production.

 
MARKETING
 

     Algos plans to market its products either directly or through  co-marketing
or  licensing agreements with pharmaceutical  companies. The Company's marketing
strategy is to develop a direct sales force in the U.S. in market segments  with
relatively  concentrated  distribution  channels  to  target  hospitals,  health
maintenance organizations and pharmaceutical buyer groups. Algos does not expect
to establish a direct  sales capability until  such time as one  or more of  its
products  in development  receives marketing  approval from  the FDA.  In market
segments that  require large  or  specialized sales  capabilities, such  as  OTC
analgesic  products  and  certain  foreign  countries,  the  Company  will  seek
strategic alliances with  leading pharmaceutical  companies such  as the  McNeil
License  Agreement. Implementation  of this strategy  will depend  on the market
potential  of  the  Company's  products,  its  financial  resources  and  timely
regulatory approvals.

 
COMPETITION
 

     The  Company's products under  development are expected  to address several
different markets.  The  Company's  proposed products  will  be  competing  with
currently  existing  or future  products of  other companies.  Competition among
these products will be based on,  among other things, product efficacy,  safety,
reliability,  availability,  price and  patent position.  Many of  the Company's
existing  or  potential  competitors   have  substantially  greater   financial,
technical  and  human resources  than  the Company,  may  be better  equipped to
develop, manufacture and market products  and have more extensive experience  in
pre-clinical  testing and human clinical trials. These companies may develop and
introduce products and processes competitive to those of the Company.

 

     The Company competes  with pharmaceutical companies  that develop,  produce
and  market products  in the United  States, Europe and  elsewhere. In addition,
academic  institutions,  government  agencies  and  other  public  and   private
organizations conducting research may seek patent protection, discover new drugs
or  establish  collaborative  arrangements  for  drug  research.  The  Company's
narcotic analgesic and  anesthetic products, when  developed and marketed,  will
compete   with  products  generally   marketed  by  medium-sized  pharmaceutical
companies. In other analgesic segments, such as antiarthritic and OTC  analgesic
products, the Company's products, when developed and marketed, will compete with
products marketed by some of the largest pharmaceutical companies in the U.S. In
these   segments,   the  Company   may  enter   into  license   agreements  with
pharmaceutical companies having greater resources than the Company.

 
PATENTS, TRADE SECRETS AND LICENSES
 
Patent Rights
 
     The Company  seeks  to protect  is  proprietary position  by,  among  other
methods,  filing United States  and foreign patent  applications with respect to
the development of its products and  their uses. The Company plans to  prosecute
and  defend its patent applications, issued patents and proprietary information.
The Company's ability to compete effectively will depend in part on its  ability
to develop and maintain proprietary aspects of its planned products. The Company
has  an exclusive  license for  three U.S. patents  and six  pending U.S. patent
applications under  its agreement  with  The Medical  College of  Virginia,  and
several corresponding pending foreign patent applications. The Company also owns
one  pending  U.S.  patent  application  and  plans  to  file  additional patent
applications.
 

     Reflecting the  Company's major  research  and development  direction,  its
patent  program is primarily focused on securing intellectual property rights to
technology for  the  following  categories  of its  business:  (i)  the  use  of
pharmacologically  acceptable  NMDA  antagonists for  the  management  of acute,
chronic, pre-operative  and post-operative  pain states,  (ii) the  use of  NMDA
antagonists  for the potentiation of local anesthesia  and (iii) the use of NMDA
antagonists  for  the  treatment  of  other  conditions  such  as  urge  urinary
incontinence.    The   Company    is   employing    an   aggressive   dual-level

 
                                       28

<PAGE>
strategy of  claiming  its drug  discoveries  mechanistically and  in  terms  of
specific  therapeutics.  This strategy  is  intended to  maximize  the Company's
opportunities for obtaining the broadest  possible patent protection and at  the
same  time, result in issued patents with complementary and mutually reinforcing
claims.

and methods for inhibiting the development of tolerance to and/or dependence  on
a   variety  of   narcotic  analgesics  including   codeine,  fentanyl,  heroin,
hydrocodone, morphine  and  oxycodone  employing any  one  of  several  specific
nontoxic  NMDA  antagonists  including  dextromethorphan  and  dextrorphan; U.S.
Patent No. 5,352,683 entitled 'Method for the Treatment of Chronic Pain' (issued
October 4, 1994) claims a method for treating chronic pain employing any one  of
several  specific nontoxic NMDA  antagonists such as  those previously mentioned
and, U.S.  Patent No.  5,502,058 entitled  'Method for  the Treatment  of  Pain'
(issued   March  26,  1996)  covers  a  method  of  alleviating  preexisting  or
prospectively  occurring  pain  employing  dextromethorphan  or  dextrorphan  in
combination with lidocaine.
 

     The Company has been notified that U.S. Patent No. 5,556,838 will be issued
on  or about September 17, 1996. This patent claims a composition containing any
nontoxic NMDA  antagonist,  or  any  nontoxic  substance  that  blocks  a  major
intracellular  consequence of NMDA  receptor activation, and  any one of several
addictive substances, including morphine. A related patent application covers  a
companion   method  for  inhibiting  the  development  of  tolerance  to  and/or
dependence on  such addictive  substances.  In addition,  the Company  has  been
assigned  a pending  U.S. patent application  covering the  treatment of urinary
incontinence  which  has  recently  been  examined.  A  corresponding   regional
application designating numerous foreign jurisdictions has been filed.

 
     The  patent positions of  pharmaceutical firms, including  the Company, are
generally  uncertain   and  involve   complex  legal   and  factual   questions.
Consequently,  even  though  the  Company is  currently  prosecuting  its patent
applications with  the U.S.  Patent  and Trademark  Office ('PTO')  and  certain
foreign  patent  authorities,  the Company  does  not  know whether  any  of its
applications will  result in  the issuance  of any  patents, or  if any  patents
issue,  whether they will provide significant  proprietary protection or will be
circumvented  or  invalidated.  Since  patent  applications  in  the  U.S.   are
maintained  in secrecy until patents issue, and since publication of discoveries
in the scientific or patent literature tend to lag behind actual discoveries  by
several  months, the Company cannot be certain  that it was the first creator of
inventions claimed by pending  patent applications or that  the Company was  the
first   to   file   patent   applications  for   such   inventions.   See  'Risk
Factors -- Uncertain Ability to Protect Proprietary Technology.'
 
     The Company also relies upon trade secrets, know-how, continuing innovation
and licensing opportunities to develop and maintain its competitive position. It
is the Company's current practice to require its employees, consultants, members
of its  Medical and  Research Advisory  Board, sponsored  researchers and  other
advisors   to  execute  confidentiality  agreements  upon  the  commencement  of
employment or  consulting  relationships  with  the  Company.  These  agreements
provide  that  all  confidential  information developed  or  made  known  to the
individual during the course of  the individual's relationship with the  Company
is  to  be kept  confidential and  not  disclosed to  third parties,  subject to
certain exceptions. In the  case of employees, the  agreements provide that  all
inventions  conceived by the  individual shall be the  exclusive property of the
Company. There can be no assurance, however, that these agreements will  provide
meaningful  protection for the  Company's trade secrets  or adequate remedies in
the event of unauthorized use or disclosure of such information.
 
     The Company engages in collaborations and sponsored research agreements and
enters into  pre-clinical  and clinical  testing  agreements with  academic  and
research institutions and U.S. government agencies, such as NIH. Consistent with
pharmaceutical  industry and academic  standards, and the  rules and regulations
under the Federal Technology Transfer Act of 1986, these agreements may  provide
that  developments and  results will  be freely  published, that  information or
materials supplied by the Company will  not be treated as confidential and  that
the  Company may be required to negotiate a license to any such developments and
results in order to commercialize products  incorporating them. There can be  no
assurance  that the Company will be able to successfully obtain any such license
at a
 
                                       29
 
<PAGE>
<PAGE>
reasonable cost or that such developments and results will not be made available
to competitors of the Company on an exclusive or a non-exclusive basis.
 
     The Company's  success depends  in part  on its  ability to  obtain  patent
protection  for  its products  and  to preserve  its  trade secrets  and operate
without infringing on the proprietary rights of third parties. No assurance  can
be given that the Company's pending patent applications will be approved or that
any  patents will provide competitive advantages for its products or will not be
successfully challenged or circumvented by its competitors. No assurance can  be
given  that patents  do not  exist or  could not  be filed  which would  have an
adverse effect on the Company's ability  to market its products or maintain  its
competitive position with respect to its products. The Company's patents may not
prevent  others from  developing competitive products  using related technology.
Other entities may obtain patents which cover aspects of the Company's  products
or  processes which are necessary for  or useful to the development, manufacture
or use of the Company's  products. As a result, the  Company may be required  to
obtain  licenses from  others to develop,  manufacture or  market such products.
There can be  no assurance  that the  Company will be  able to  obtain any  such
licenses on commercially reasonable terms, if at all.
 
     No  assurance can be given  that any patent issued  to, or licensed by, the
Company will provide protection that has commercial significance. In this regard
the patent position of pharmaceutical compounds and compositions is particularly
uncertain. Even issued patents may  be later modified or  revoked by the PTO  in
proceedings  instituted by the Company or  others. In addition, no assurance can
be given that the Company's  patents will afford protection against  competitors
with  similar compounds  or technologies,  that others  will not  obtain patents
claiming  aspects  similar  to  those  covered  by  the  Company's  patents   or
applications,  or that the patents of others  will not have an adverse effect on
the ability of the Company to do business. The Company's patents may not prevent
others from developing competitive positions using related technology.
 
Licenses
 

     The Company has entered into a license agreement, which was last amended in
June 1996 (the 'Amendment'),  with The Medical College  of Virginia for  certain
patents  or pending patent applications owned by The Medical College of Virginia
in the field of pain management in the country in which any such product or part
thereof is made, used, sold or  manufactured. In consideration for the terms  of
the  Amendment, the Company issued 100,000 shares of Series B Preferred Stock to
The Medical College  of Virginia. The  Company pays no  license signing fees  or
milestone  payments. Royalties for the life of the patent equal 4% of net sales.
If a product is combined with a drug or other substance for which the Company is
paying an additional royalty,  the royalty rate paid  to The Medical College  of
Virginia  is generally reduced by the amount  of such additional royalty. If the
Company enters into sublicensing agreements  for a covered product, the  Company
will  pay The Medical College of Virginia  50% of royalty payments received from
such sublicensees' net sales for each year until the payments total $500,000 for
such year, 33% until the payments total an additional $500,000 for such year and
25% thereafter. The McNeil  License Agreement is a  sublicense agreement of  the
Company's license agreement with The Medical College of Virginia.

 

     The  Company has entered into a license agreement with MIT for an exclusive
worldwide license in connection with patent rights relating to a patent owned by
MIT. This patent covers a process for the ultrasound enhancement of  transdermal
drug delivery.

 
GOVERNMENT REGULATION
 
     In the U.S., pharmaceutical products intended for therapeutic or diagnostic
use  in humans are subject to rigorous FDA regulation. The process of completing
clinical trials and obtaining FDA approvals for  a new drug is likely to take  a
number  of years and require the expenditure of substantial resources. There can
be no assurance that any product will  receive such approval on a timely  basis,
if  at all. See 'Risk  Factors -- Government Regulation;  No Assurance of United
States or Foreign Regulatory Approval.'
 
     Applicable   FDA   regulations   treat   the   Company's   combination   of
dextromethorphan  with analgesics such as  morphine, acetaminophen and ibuprofen
and local anesthetics such as lidocaine as
 
                                       30
 
<PAGE>
<PAGE>
new drugs and require  the filing of  an NDA and approval  by the FDA.  However,
since  each of these drugs  has been separately approved  by the FDA, management
believes that the risks associated with the development of these new proprietary
drugs are less than the risks inherent in new molecular drug discovery.
 
     The steps required before  a new pharmaceutical product  for use in  humans
may be marketed in the U.S. include (i) pre-clinical studies, (ii) submission to
the  FDA of an  Investigational New Drug application  ('IND'), which must become
effective  before   human  clinical   trials   commence,  (iii)   adequate   and
well-controlled  human clinical trials to establish the safety and effectiveness
of the product, (iv) submission  of an NDA to the  FDA, and (v) FDA approval  of
the NDA prior to any commercial sale or shipment of the product.
 
     Pre-clinical studies include laboratory evaluation of product chemistry and
formulation,  as  well as  animal studies,  to assess  the potential  safety and
effectiveness of  the  product. The  results  of the  pre-clinical  studies  are
submitted  to the FDA as a  part of an IND and are  reviewed by the FDA prior to
the commencement  of  human clinical  trials.  Unless  the FDA  objects  to,  or
otherwise  responds to, an IND, the IND  will become effective 30 days following
its receipt by the FDA.
 
     Clinical  trials  are  typically  conducted  in  three  sequential  phases,
although phases may overlap. In Phase I, the investigational new drug usually is
administered  to  healthy  human  subjects and  is  tested  for  safety (adverse
effects),   dosage,   tolerance,   metabolism,   distribution,   excretion   and
pharmacodynamics (clinical pharmacology). Phase II involves studies in a limited
patient population to (i) determine the effectiveness of the investigational new
drug  for  specific indications,  (ii)  determine dosage  tolerance  and optimal
dosage and (iii)  identify possible adverse  effects and safety  risks. When  an
investigational  new drug  is found  to be effective  and to  have an acceptable
safety profile  in Phase  II  evaluation, Phase  III  trials are  undertaken  to
further evaluate clinical effectiveness and to further test for safety within an
expanded  patient population  at geographically dispersed  clinical study sites.
For analgesic  drugs,  Phase II  analgesic  efficacy studies  have  historically
served  as the pivotal studies for an  NDA. Phase III studies for these products
normally focus greater attention on safety in larger patient populations  rather
than  efficacy. There can  be no assurance that  Phase I, Phase  II or Phase III
testing will be completed successfully within  any specified time period, if  at
all,  with respect  to any  of the Company's  products subject  to such testing.
Furthermore, the FDA may  suspend clinical trials at  any time there is  concern
that the participants are being exposed to an unacceptable health risk.
 

     The   results  of  pharmaceutical  development,  pre-clinical  studies  and
clinical trials are submitted to the FDA in  the form of an NDA for approval  of
the  marketing  and commercial  shipment  of the  product.  The FDA  may require
additional testing or information before approving the NDA. The FDA may deny  an
NDA  approval  if  safety, efficacy  or  other regulatory  requirements  are not
satisfied. Moreover,  if regulatory  approval of  the product  is granted,  such
approval  may  require post-marketing  testing and  surveillance to  monitor the
safety of the product or may entail limitations on the indicated uses for  which
the  product  may be  marketed. Finally,  product approval  may be  withdrawn if
compliance with  regulatory standards  is not  maintained or  if problems  occur
following initial marketing.

 
     At  present, pharmaceutical products generally may not be exported from the
U.S. for other than research purposes until the FDA has approved the product for
marketing in the U.S. However, a company may apply to the FDA for permission  to
export  finished products or partially processed products to a limited number of
countries prior to obtaining FDA approval for marketing in the U.S.
 

     The Company is  also subject to  regulation under federal  and state  laws,
including  the Occupational Safety and  Health Act, the Environmental Protection
Act, the  Clean  Air Act,  national  restrictions on  technology  transfer,  and
import,  export  and  customs regulations.  In  addition, all  of  the Company's
products that  contain narcotics  are  subject to  DEA regulations  relating  to
storage,  distribution  and physician  prescribing procedures.  There can  be no
assurance that any portion of the  regulatory framework under which the  Company
currently operates will not change and that such change will not have a material
effect on the current and anticipated operations of the Company.

 
     Whether or not FDA approval has been obtained, approval of a pharmaceutical
product  by comparable governmental regulatory  authorities in foreign countries
must be obtained  prior to the  commencement of clinical  trials and  subsequent
marketing of such product in such countries. The
 
                                       31

<PAGE>
approval  procedure varies from country to country, and the time required may be
longer or shorter than that required for FDA approval.
 
EMPLOYEES
 

     At June  30,  1996,  the  Company had  nine  employees  and  two  executive
consultants,  including five Ph.Ds and/or MDs.  In addition, the Company engages
consultants from time to time to perform services on a per diem or hourly basis.

 
FACILITIES
 
     The Company's executive  office, located at  Collingwood Plaza, 4900  Route
33,  Neptune, New  Jersey 07753,  is leased  under a  five-year agreement, which
expires in 1997. The lease is  renewable for two consecutive five-year  periods.
The  leased property consists  of approximately 2,000 square  feet of office and
storage space. The Company is in the process of expanding its facilities to meet
anticipated future staffing.
 
LEGAL PROCEEDINGS
 
     There are no legal proceedings pending against the Company.

     (1) All such options were exercised in January 1995. The Board of Directors
determined that the exercise price of the options did not exceed the fair market
value of the Common  Stock at the  time of exercise.  Accordingly, there was  no
value realized at the time of exercise.

 

     (2)  Based on the fair market value of  the Common Stock as of December 31,
1995 ($0.12 per  share) as  determined by the  Board of  Directors, the  Company
determined that there were no in-the-money options at December 31, 1995.

 
Employment Agreements
 

     Each of Mr. Lyle and Drs. Caruso and Bello has an employment agreement with
the  Company  which  expires December  31,  1997. Each  employment  agreement is
automatically renewable  for


                                       36
 

<PAGE>
<PAGE>


successive  one-year  terms  unless  terminated  by either the  employee  or the
Company.  Mr.  Lyle's  agreement  provides that Mr. Lyle will be employed as the
President and Chief  Executive  Officer of the Company and that the Company will
use its best  efforts to cause Mr. Lyle to be elected to the Board of  Directors
for the term of the agreement.  Dr. Caruso's  agreement provides that he will be
employed as the  Executive  Vice  President  for Research and  Development.  Dr.
Bello's  agreement  provides  that he will be  employed  as the  Executive  Vice
President for Technology Transfer and Manufacturing.  Under the agreements, each
executive will be entitled to certain upward adjustments to the preceding year's
base salary.  Drs. Caruso and Bello are entitled to receive continuing  payments
amounting to twelve months and six months salary, respectively,  in the event of
their  termination by the Company without cause. Each executive may also receive
bonuses for individual  accomplishment  of key milestone  events in such amounts
and on such terms as the Board of Directors may determine.  Mr. Lyle's agreement
acknowledges  that  during  the  employment  period he will also  serve as Chief
Executive  Officer  of U.S.  Medical  Development,  Inc.  ('USMDI'),  a Delaware
corporation  incorporated on January 4, 1994 by the founders of the Company. The
agreements  provide the  executives  with  certain  rights  under the 1994 Stock
Option Plan. See 'Stock Option Plans.'

 
STOCK OPTION PLANS
 
1994 Stock Option Plan
 

     Effective  January 1994,  the Company established  the Algos Pharmaceutical
Corporation 1994 Stock  Option Plan  (the '1994  Option Plan')  under which  key
employees  may be granted  options to purchase  shares of the  Common Stock. The
1994 Option Plan is intended to  assist the Company in attracting and  retaining
employees  of outstanding  ability and  to promote  the identification  of their
interests with  those  of the  stockholders  of  the Company.  The  Company  has
reserved a total of 830,000 shares of Common Stock for issuances under the plan.

 
     Unless  sooner terminated by  the Board of Directors,  the 1994 Option Plan
will expire ten years after its inception. The 1994 Option Plan is  administered
by the Board of Directors, which has the authority to select eligible employees,
grant options under the plan and determine the terms, price, and form of payment
for  each grant. Awards under the 1994  Option Plan will generally be granted at
an exercise price equal to the then fair market value per share of Common Stock.
Options granted under the 1994 Option Plan shall not be transferable and upon an
employee's death,  all options  that  have been  granted  to such  employee  are
generally deemed to be exercisable.
 
1996 Stock Option Plan
 
     In  April 1996,  the Company  adopted the  Algos Pharmaceutical Corporation
1996 Stock  Option  Plan (the  '1996  Option Plan').  The  1996 Option  Plan  is
intended  to assist  the Company in  attracting and retaining  key employees and
independent consultants of outstanding ability and to promote the identification
of their  interests with  those of  the stockholders  of the  Company. The  1996
Option Plan permits the grant of non-qualified stock options and incentive stock
options  to  purchase shares  of Common  Stock  covering 415,000  authorized but
unissued or reacquired shares of Common Stock, subject to adjustment to  reflect
events  such  as stock  dividends, stock  splits, recapitalizations,  mergers or
reorganizations of or by the Company.
 
     Unless sooner terminated by  the Board of Directors,  the 1996 Option  Plan
will  expire on January 31, 2006. Such  termination will not affect the validity
of any option outstanding under the 1996 Option Plan on the date of termination.
 

     Prior to the  Offering, the  Board of  Directors will  administer the  1996
Stock  Option  Plan. Following  the closing  of  the Offering,  the Compensation
Committee of the Board of Directors  (the 'Committee') will administer the  1996
Stock  Option Plan (which is intended to  satisfy the requirements of Rule 16b-3
under the Exchange Act, and Section 162(m) of the Internal Revenue Code of 1986,
as amended (the 'Code')). Subject to the terms and conditions of the 1996 Option
Plan, the Committee has the authority to  select the persons to whom grants  are
to  be made, to designate the number of  shares of Common Stock to be covered by
such grants,  to determine  the  exercise price  of  options, to  establish  the
period of exercisability of options, and to make all other determinations and to
take all other actions necessary or advisable for the administration of the 1996
Option  Plan. The dates on  which options first become  exercisable and on which
they expire shall be set forth in individual option agreements setting




 
                                       37
 

<PAGE>
<PAGE>

forth the specific terms of the options, subject to the requirements of the 1996
Stock Option Plan. Such  agreements  will generally  provide that options expire
within  one year  following  the  termination  of the  optionee's  status  as an
employee or consultant  of the Company (or a subsidiary)  although the Committee
may provide  that options  continue to be  exercisable  following a  termination
without  'Cause' (as defined in the 1996 Stock  Option Plan) or  otherwise.  The
Committee  also may, in its  discretion,  provide by the terms of an option that
such option will expire at specified times following,  or become  exercisable in
full upon, the occurrence of certain specified  'extraordinary corporate events'
including a merger,  consolidation  or dissolution of the Company,  or a sale of
substantially all of the Company's  assets,  but in such event the Committee may
also give  optionees  the right to exercise  their  outstanding  options in full
during  some  period  prior to such  event,  even though the rights have not yet
otherwise become fully exercisable.

 

     Incentive  stock options ('Incentive Stock Options') granted under the 1996
Stock Option Plan will be designed to comply with the provisions of the Code and
will be  subject to  certain  restrictions contained  in  the Code.  Among  such
restrictions,  Incentive Stock Options must have an exercise price not less than
the fair market value of a share of Common Stock on the date of grant, may  only
be granted to employees, must expire within a specified period of time following
the  optionee's termination of employment, and  must be exercised within the ten
years after the date of grant.

 

     In the case of an incentive stock option granted to an individual who  owns
(or  is deemed to  own) at least 10%  of the total combined  voting power of all
classes of stock of the Company, the exercise price must be at least 110% of the
fair market value  of a  share of Common  Stock on  the date of  grant and  must
expire  five years after grant. Furthermore,  the 1996 Option Plan provides that
the aggregate fair market value (determined  at the time the option is  granted)
of  shares with respect to which incentive  stock options may be exercisable for
the first time during any calendar  year, may not exceed $100,000 per  employee.
Options for shares, the fair market value of which exceeds the $100,000 per year
limit, are non-qualified stock options.

 

     Options   intended  to  satisfy  the  requirements  for  'performance-based
compensation' under Section 162(m) of the Code must also have an exercise  price
of  not less  than fair market  value on the  date granted and  must comply with
other limitations and restrictions.

 

     The  1996  Option  Plan  may  be  amended  by  the  Committee,  subject  to
stockholder  approval if such approval is then  required by applicable law or in
order for the  1996 Option Plan  and options granted  thereunder to continue  to
satisfy  the requirements of Rule 16b-3 under the Exchange Act or Section 162(m)
of the Code.

 

     The 1996 Option Plan permits the payment of the option exercise price to be
made in cash (which may include an  assignment of the right to receive the  cash
proceeds  from the  sale of  Common Stock  subject to  the option  pursuant to a
'cashless exercise' procedure) or by delivery  of shares of Common Stock  valued
at  their  fair  market value  on  the date  of  exercise or  delivery  of other
property, or by  a recourse  promissory note  payable to  the Company,  or by  a
combination  of the foregoing.  As a condition of  exercise, optionees must also
provide for  the  payment of  withholding  tax  obligations of  the  Company  in
connection with such exercise.

 
     Options  granted  under  the 1996  Option  Plan shall  not  be transferable
otherwise than by will, by the laws of descent and distribution or pursuant to a
qualified domestic  relations  order  (as  defined in  the  Code),  and  may  be
exercised  during the optionee's lifetime only by  the optionee or, in the event
of the optionee's legal disability, by the optionee's legal representative.
 
1996 Non-Employee Director Stock Option Plan
 

     In April  1996, the  Company also  adopted the  1996 Non-Employee  Director
Stock  Option Plan (the 'Director Plan') covering 83,000 authorized but unissued
or reacquired shares of  Common Stock, subject to  adjustment to reflect  events
such   as  stock   dividends,  stock   splits,  recapitalizations,   mergers  or
reorganizations of or by  the Company. The Director  Plan is intended to  assist
the  Company  in  attracting  and  retaining  qualified  non-employee  directors
('Outside Directors').

 
     Following the  consummation of  the  Offering, the  Director Plan  will  be
administered  by the Board  of Directors and options  granted under the Director
Plan are intended to satisfy the  requirements of Rule 16b-3 under the  Exchange
Act.  The Director  Plan provides  for automatic  grants of  non-qualified


                                       38
 

<PAGE>
<PAGE>

stock options to purchase 10,000 shares of Common Stock to each Outside Director
at the time of appointment or election to the Board of Directors.

 

     The exercise price of the options shall be the fair market value of a share
of  Common Stock on the  date of grant. Each  option shall become exercisable in
cumulative annual installments of  one-third on each of  the first three  annual
meetings  of the Company's stockholders  following the date of  grant so long as
the Outside Director continues to serve as a director of the Company;  provided,
however,  to the  extent permitted  by Rule  16b-3, the  Board of  Directors may
accelerate  the  exercisability  of  options  upon  the  occurrence  of  certain
specified  extraordinary corporate transactions or  events and provided further,
that in any event, upon the occurrence  of a 'Change in Control' of the  Company
(as  defined  in  the  Director  Plan)  all  outstanding  options  shall  become
immediately exercisable. No portion of an option shall be exercisable after  the
tenth  anniversary of  the date of  grant and no  portion of an  option shall be
exercisable following termination of the Outside Director's services as director
of the Company.

 

     Unless sooner terminated by the Board of Directors, the Director Plan  will
expire ten years after the date of its adoption. Such expiration will not affect
the validity of any option outstanding on the date of termination.

 

     Each  Outside Director serving as a director of the Company as of the close
of each subsequent annual stockholders'  meeting at which directors are  elected
shall be granted an option to purchase 5,000 shares of Common Stock.

 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES WITH RESPECT TO OPTIONS UNDER THE 1994
OPTION PLAN, 1996 OPTION PLAN AND THE DIRECTOR PLAN
 
     An  optionee generally will not recognize taxable  income on the grant of a
non-qualified stock option under the 1994  Option Plan, 1996 Option Plan or  the
Director  Plan,  but will  recognize  ordinary income  on  the exercise  of such
option. The amount of income recognized  on the exercise of an option  generally
will  be equal to the excess, if any, of  the fair market value of the shares at
the time of  exercise over  the aggregate exercise  price paid  for the  shares,
regardless  of whether the exercise price is paid  in cash or in shares or other
property. Where ordinary income is recognized by an optionee in connection  with
the exercise of an option, the Company generally will be entitled to a deduction
equal to the amount of ordinary income so recognized.
 
     An  optionee generally  will not recognize  taxable income  upon either the
grant or exercise  of an incentive  stock option granted  under the 1996  Option
Plan. Generally, upon the sale or other taxable disposition of the shares of the
Common  Stock acquired upon exercise of  an incentive stock option, the optionee
will recognize long-term capital gain in an amount equal to the excess, if  any,
of  the  amount realized  in such  disposition over  the option  exercise price,
provided that no disposition of the shares has taken place within either (a) one
year from the date of exercise  or (b) two years from  the date of grant of  the
incentive  stock option. If the shares of the Common Stock are sold or otherwise
disposed of before the end of the one-year and two-year periods specified above,
the difference between the  incentive stock option exercise  price and the  fair
market  value of the shares on the date of the incentive stock option's exercise
generally will be taxable as ordinary income; the balance of the amount realized
from such disposition, if any, will be  taxed as capital gain. If the shares  of
the  Common Stock  are disposed  of before  the expiration  of the  one-year and
two-year periods and the amount realized is  less than the fair market value  of
the  shares at the date of exercise, the optionee's ordinary income generally is
limited to excess, if any, of the  amount realized in such disposition over  the
option  exercise  price  paid.  The  Company  (or  other  employer  corporation)
generally will be entitled to a tax deduction with respect to an incentive stock
option only to the extent  the optionee has ordinary  income upon sale or  other
disposition of the shares of the Common Stock.
 
     The  rules governing the tax treatment of options and an optionee's receipt
of shares in connection with such grants are quite technical, so that the  above
description  of tax consequences  is necessarily general in  nature and does not
purport to be complete. Moreover,  statutory provisions are, of course,  subject
to  change,  as are  their interpretations,  and their  application may  vary in
individual circumstances. Finally, the  tax consequences under applicable  state
law may not be the same as under the federal income tax laws.

                          DESCRIPTION OF CAPITAL STOCK
 

     Upon consummation  of the  Offering, the  authorized capital  stock of  the
Company  will consist of 50,000,000  shares of Common Stock,  $.01 par value per
share, and  10,000,000 shares  of Preferred  Stock, $.01  par value  per  share,
100,000 of which have been designated as Series B Preferred Stock.

 
COMMON STOCK
 
     Holders  of Common Stock  are entitled to  one vote for  each share held of
record on all matters submitted to a vote of the stockholders. Holders of Common
Stock are not entitled to cumulative voting rights. Holders of Common Stock  are
entitled  to receive ratably such  dividends as may be  declared by the Board of
Directors out  of  funds  legally  available  therefor.  The  Company  does  not
anticipate  any cash dividends on  Common Stock will be  paid in the foreseeable
future. See 'Dividend  Policy.' In the  event of a  liquidation, dissolution  or
winding up of the Company, holders of Common Stock are entitled to share ratably
in all assets remaining after payment of liabilities, and payments to holders of
Preferred  Stock. The holders of  Common Stock have no  preemptive rights and no
right to convert  their Common  Stock into any  other securities.  There are  no
redemption  or sinking fund  provisions applicable to the  Common Stock. All the
outstanding shares of  Common Stock  are, and the  shares of  Common Stock  into
which  the Preferred  Shares will be  converted upon completion  of the Offering
will be, validly issued, fully paid and non-assessable.
 
PREFERRED STOCK
 

     Under its Amended  and Restated Certificate  of Incorporation, the  Company
has  authority to issue 10,000,000 shares of Preferred Stock, $.01 par value per
share. The  Board  of Directors  has  the  authority, without  approval  of  the
stockholders,  to issue shares of  Preferred Stock in one  or more series and to
fix  the   number   of  shares   and   the  rights,   preferences,   privileges,
qualifications,  restrictions  and  limitations of  each  series.  Following the
consummation of the Offering, 100,000 shares of Series B Preferred Stock will be
issued and outstanding.  The Series  B Preferred  Stock is  convertible, at  the
option  of the holder, into Common Stock at any time after February 1, 1997. The
holders of Series B Preferred Stock will  receive one share of Common Stock  for
each  share of Series B Preferred Stock owned by such holder, subject to certain
anti-dilution provisions.

 
REGISTRATION RIGHTS
 

     The holders of the Common Stock and  Series A Preferred Stock prior to  the
Offering  (the 'Stockholders'),  are parties  to a  stockholders' agreement (the
'Stockholders'  Agreement')  which  provides  such  Stockholders  with   certain
registration  rights. Under the  Stockholders' Agreement, and upon the automatic
conversion of the Series A  Preferred  Stock  to   shares   of   Common   Stock,
the  Stockholders  are  entitled  to  certain  registration  rights with respect
to shares  of Common Stock, including a  demand registration  right   which   is
exercisable on one occasion after 270 days from the date of this Prospectus  and
certain 'piggyback' registration rights which are exercisable in connection with
registrations of shares initiated by the Company.

 

     At any time after February 1, 1997, holders of the Series B Preferred Stock
have the right to require the Company to register the resale of the Common Stock
that such holders receive upon conversion of the Series B Preferred Stock.

 
DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     Upon  the consummation of the Offering, the  Company will be subject to the
provisions  of  Section  203  of  the  Delaware  General  Corporation  Law,   an
anti-takeover  law. In general,  Section 203 prohibits  a publicly-held Delaware
corporation from  engaging  in  a 'business  combination'  with  an  'interested
stockholder'  for a period of  three years after the  date of the transaction in
which the person became  an interested stockholder  unless such transaction  was
approved  in a  prescribed manner or  another prescribed  exception applies. For
purposes of Section 203, a 'business combination' is defined broadly to  include
a  merger, asset sale or  other transaction resulting in  a financial benefit to
the interested stockholder,  and subject to  certain exceptions, an  'interested
stockholder'  is a person who, together  with affiliates and associates owns (or
within three  years prior,  did own)  15% or  more of  the corporation's  voting
stock.
 

     Upon  consummation  of the  Offering,  the Company's  Amended  and Restated
By-Laws provide for a Board of Directors classified into three classes, with the
Directors elected  at  the Company's  1996  annual meeting  divided  into  three
classes  and  serving  initial  terms  expiring  at  the  1997,  1998  and  1999

 
                                       42
 

<PAGE>
<PAGE>
annual stockholders' meetings, respectively. Thereafter, Directors in each class
will be elected for three year terms.  No determination has yet been made as  to
the  selection of any of the current  directors for nomination for election in a
particular class. All  directors elected  to the Company's  classified Board  of
Directors will serve until the election and qualification of their successors or
their  earlier resignation or  removal. The Board of  Directors is authorized to
create new directorships and to fill such positions so created and is  permitted
to  specify the  class to which  such new  position is assigned,  and the person
filling such position  would serve for  the term applicable  to that class.  The
Board of Directors (or its remaining members, even though less than a quorum) is
also  empowered to fill  vacancies on the  Board of Directors  occurring for any
reason for the  remainder of the  term of the  class of Directors  in which  the
vacancy  occurred. After classification of the Board of Directors, Directors may
only be removed  for cause.  These provisions are  likely to  increase the  time
required for stockholders to change the composition of the Board of Directors.
 

     The   Company's  Amended  and  Restated  By-Laws  also  provide  that,  for
nomination to  the Board  of Directors  or  for other  business to  be  properly
brought  by a stockholder before a meeting of stockholders, the stockholder must
first have  given timely  notice thereof  in  writing to  the Secretary  of  the
Company.  To be timely,  a stockholder's notice generally  must be delivered not
less than sixty days nor more than  ninety days prior to the annual meeting.  If
the meeting is not an annual meeting, the notice must generally be delivered not
more  than ninety days prior to the special meeting and not later than the later
of sixty days prior  to the special  meeting and ten days  following the day  on
which public announcement of the meeting is first made by the Company. Only such
business  shall be conducted at a special  meeting of stockholders as is brought
before the meeting pursuant to the Company's notice of meeting. The notice by  a
stockholder  must  contain, among  other things,  certain information  about the
stockholder delivering  the notice  and, as  applicable, background  information
about the nominee or a description of the proposed business to be brought before
the meeting.

 

     The  Company's  Amended  and  Restated  Certificate  of  Incorporation also
requires that any action  required or permitted to  be taken by stockholders  of
the  Company must  be effected  at a  duly called  annual or  special meeting of
stockholders and may not be effected  by a consent in writing. Special  meetings
may  be called only by the Chairman of the Board or the President of the Company
or by the majority of the whole Board of Directors.

 

     The  Delaware  General   Corporation  Law  provides   generally  that   the
affirmative  vote of a majority of the shares  entitled to vote on any matter is
required to  amend  a corporation's  certificate  of incorporation  or  by-laws,
unless  the corporation's certificate  of incorporation or  by-laws, as the case
may be,  requires  a greater  percentage.  The Company's  Amended  and  Restated
Certificate  of Incorporation requires the affirmative vote of the holders of at
least 66 2/3% of the outstanding voting stock of the Company to amend or  repeal
any  of  the provisions  discussed in  this section  entitled 'Delaware  Law and
Certain Charter  and By-Law  Provisions' relating  to the  Amended and  Restated
Certificate  of Incorporation  or to reduce  the number of  authorized shares of
Common Stock and Preferred  Stock. Such 66  2/3% vote is  also required for  any
amendment  to or  repeal of  the Company's Amended  and Restated  By-Laws by the
stockholders. The Amended and Restated By-Laws  may also be amended or  repealed
by  a majority  vote of the  Board of  Directors. Such 66  2/3% stockholder vote
would be in  addition to any  separate class vote  that might in  the future  be
required  pursuant  to the  terms  of any  Preferred  Stock that  might  then be
outstanding.

 

     The provisions  of  the  Company's  Amended  and  Restated  Certificate  of
Incorporation  and Amended and Restated By-Laws  discussed above could make more
difficult or discourage a proxy contest or other change in the management of the
Company or the acquisition or attempted acquisition of control by a holder of  a
substantial  block of the  Company's stock. It is  possible that such provisions
could make it more difficult to  accomplish, or could deter, transactions  which
stockholders may otherwise consider to be in their best interests.

 

     As permitted by the Delaware General Corporation Law, the Company's Amended
and Restated Certificate of Incorporation provides that Directors of the Company
shall  not be personally liable to the  Company or its stockholders for monetary
damages for breach of their fiduciary duties as Directors, except for  liability
(i) for any breach of their duty of loyalty to the Company and its stockholders,
(ii)  for  acts or  omissions not  in  good faith  or which  involve intentional
misconduct or  a  knowing violation  of  law,  (iii) for  unlawful  payments  of
dividends   or   unlawful  stock   repurchases   or  redemptions,   as  provided

 
                                       43
 

<PAGE>
<PAGE>
in Section  174  of  the  Delaware  General Corporation  Law  or  (iv)  for  any
transaction from which the Director derives an improper personal benefit.
 

     The Company's Amended and Restated Certificate of Incorporation and Amended
and  Restated By-Laws provide that the Company shall indemnify its Directors and
officers to the fullest extent permitted by Delaware law and advance expenses to
such  Directors  and  officers  to  defend  any  action  for  which  rights   of
indemnification are provided.

 
                        SHARES ELIGIBLE FOR FUTURE SALE
 

     Upon  completion of this Offering, the  Company will have 15,544,123 shares
of Common Stock  outstanding (assuming  no exercise  of any  of the  outstanding
options  and warrants to purchase  Common Stock outstanding as  of June 30, 1996
and assuming the Underwriters' over-allotment option is not exercised), of which
12,044,123 are 'restricted'  shares within  the meaning  of Rule  144 under  the
Securities Act of 1933, as amended (the 'Securities Act'), and may not be resold
except  pursuant to an effective registration statement under the Securities Act
or an  applicable  exemption  from  registration,  including  Rule  144  of  the
Securities Act.

 

     In  general, under Rule 144,  as currently in effect,  a person (or persons
whose shares  are  aggregated), including  an  'affiliate', as  defined  in  the
Securities Act, is entitled to sell in any three-month period a number of shares
beneficially  owned for at least  two years that does  not exceed the greater of
(i) 1% of the then outstanding shares of Common Stock or (ii) the average weekly
trading volume in the Common Stock during the four calendar weeks preceding such
sale. Sales under Rule 144  are also subject to  certain requirements as to  the
manner  of sale, notice and the availability of current public information about
the Company. A person  who is not  an affiliate and  has beneficially held  such
shares  for at  least three  years is  entitled to  sell such  shares under Rule
144(k)  without  regard  to  the  volume,  manner  of  sale,  notice  or  public
information  requirements.  Subject  to  the  agreement  with  the  underwriters
described in  the next  paragraph, as  of  August 22,  1996, 11,640,743  of  the
restricted  shares became eligible for sale in  the public market in reliance on
Rule 144, 3,912,054 of which may be sold without regard to volume limitations.

 
     For a period of  180 days after  the closing of  the Offering, without  the
written  consent of Lehman  Brothers Inc., the  Company and all  of its existing
stockholders have agreed not to offer, sell or contract to sell, grant any offer
to purchase  or otherwise  dispose of  any  shares of  Common Stock  other  than
issuances   pursuant  to  employee  compensation  plans,  transfers  among  such
stockholders, pledges, in the case of death or permanent disability and  certain
limited charitable donations.
 
     An  employee,  officer or  director  of or  consultant  to the  Company who
purchased or was  awarded shares  or options to  purchase shares  pursuant to  a
written  compensatory  plan  or  contract  is entitled  to  rely  on  the resale
provision of Rule 701 under the Securities Act, which permits Affiliates to sell
their Rule 701 shares  without having to comply  with Rule 144's holding  period
restrictions,  in  each case  commencing 90  days after  the Effective  Date and
permits non-affiliates to sell  their Rule 701 shares  without having to  comply
with  the holding  period, public information,  volume and  notice provisions of
Rule 144.
 

     Under the Stockholders' Agreement, holders of shares of Common Stock issued
prior to the Offering or issuable under certain options and warrants outstanding
prior to the Offering are entitled  to certain registration rights with  respect
to  their shares, including a demand  registration right which is exercisable on
one occasion  after  270 days  from  the date  of  this Prospectus  and  certain
'piggyback'  registration  rights  which  are  exercisable  in  connection  with
registrations of shares initiated by the  Company. The Series B Preferred  Stock
is  convertible into an aggregate of 100,000  shares of Common Stock, subject to
certain anti-dilution  provisions,  at any  time  after February  1,  1997.  See
'Description of Capital Stock -- Registration Rights.'

 

     Prior  to the Offering, there  has been no public  market for securities of
the Company. No predictions can be made as to the effect, if any, that sales  of
shares or the availability of shares for sale will have on the prevailing market
price of the Common Stock. In addition, the Company cannot predict the number of
shares that may be sold in the future pursuant to Rule 144 or the timing of such
sales.  Sales  of  a  substantial  number  of  Restricted  Shares  could  have a
significant adverse effect on the market price of the Common Stock.

              CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS FOR
                           NON-UNITED STATES HOLDERS
 
     The following  is a  general discussion  of certain  United States  federal
income  and estate tax  consequences of the ownership  and disposition of Common
Stock by a holder who is not  a United States person (a 'Non-U.S. Holder').  For
these  purposes, the term 'United States person' is defined as any person who is
a citizen or resident of  the United States, a  corporation or a partnership  or
other  entity created or organized in the United States or under the laws of the
United States or of any State, or an estate or trust whose income is  includible
in  gross income for United States federal income tax purposes regardless of its
source. An individual  may, subject  to certain exceptions,  be deemed  to be  a
resident  alien  (as opposed  to a  non-resident alien)  for federal  income tax
purposes in several circumstances, including by  virtue of being present in  the
United  States on at least 31 days in  the calendar year and for an aggregate of
at least 183 days  during the three-year period  ending in the current  calendar
year  (counting for such purposes  all of the days  present in the current year,
one-third of the days present in  the immediately preceding year, and  one-sixth
of  the days present in the second  preceding year). Resident aliens are subject
to United  States  federal  tax as  if  they  were United  States  citizens  and
residents.
 
     This  discussion is  based on  provisions of  the Internal  Revenue Code of
1986, as amended  (the 'Code'),  existing and  proposed regulations  promulgated
thereunder  and administrative  and judicial  interpretations thereof  as of the
date hereof,  all of  which are  subject  to change.  This discussion  does  not
address  all aspects of United  States federal income and  estate taxes and does
not deal with non-United States and  U.S. state and local consequences that  may
be  relevant to Non-U.S. Holders in  light of their personal circumstances. Each
prospective purchaser of Common Stock is  advised to consult a tax advisor  with
respect  to current and  possible future tax  consequences of acquiring, holding
and disposing of Common Stock.
 
DIVIDENDS
 
     The Company does not  currently intend to pay  cash dividends on shares  of
Common  Stock. See 'Dividend  Policy.' In the  event that dividends  are paid on
shares of Common  Stock, except  as described below,  such dividends  paid to  a
Non-U.S.  Holder of  Common Stock  generally will  be subject  to withholding of
United States federal  income tax at  a 30% rate  or such lower  rate as may  be
specified  by  an  applicable  income  tax  treaty,  unless  the  dividends  are
effectively connected with the  conduct of a trade  or business of the  Non-U.S.
Holder   within  the  United  States  (or   attributable  to  a  U.S.  permanent
establishment of the Non-U.S.  Holder, if an income  tax treaty applies).  Under
current United States Treasury regulations, dividends paid to an address outside
the United States, absent definite knowledge to the contrary, may be presumed to
be  paid to a resident of such country for purposes of the withholding discussed
above,  and,  under  the  current  interpretation  of  United  States   Treasury
regulations,  for purposes of determining the applicability of a reduced rate of
withholding under a tax  treaty. Thus, Non-U.S.  Holders receiving dividends  at
addresses  outside the  United States currently  are not required  to file forms
with the payor  in order to  obtain the  benefit of an  applicable treaty  rate.
Under  proposed  United States  Treasury  regulations not  currently  in effect,
however, a Non-U.S. Holder of Common Stock who wishes to claim the benefit of an
applicable treaty rate would be required to satisfy applicable certification and
other requirements.
 
     If the  dividend is  effectively connected  with the  conduct of  a  United
States trade or business of a Non-U.S. Holder who has properly filed a Form 4224
(or  similar statement) with  the withholding agent with  respect to the taxable
year in which  the dividend  is paid, no  withholding is  required. Instead  the
dividend  (as adjusted by any applicable deductions) would be subject to regular
United States federal  income tax. In  addition, all  or a portion  of any  such
effectively  connected dividends received  by a non-U.S.  corporation may, under
certain circumstances, be subject to an additional 'branch profits tax' at a 30%
rate or such lower rate as may be specified by an applicable income tax treaty.
 
     A Non-U.S. Holder  of Common Stock  eligible for a  reduced rate of  United
States  withholding tax  pursuant to  a tax  treaty may  obtain a  refund of any
excess amounts currently withheld by filing an appropriate claim for refund with
the Internal Revenue Service ('IRS').
 
                                       45
 

<PAGE>
<PAGE>
GAIN ON DISPOSITION OF COMMON STOCK
 
     A Non-U.S. Holder generally  will not be subject  to United States  federal
income  tax  (and  no tax  generally  will  be withheld)  with  respect  to gain
recognized on a sale  or other disposition  of Common Stock so  long as (i)  the
gain  is not  effectively connected  with a  trade or  business of  the Non-U.S.
Holder within the United States, (ii) in the case of a Non-U.S. Holder who is  a
non-resident  alien individual  and holds the  Common Stock as  a capital asset,
such holder is  not present in  the United States  for 183 or  more days in  the
taxable  year of the sale or other disposition, and (iii) the Company is not and
has not been  within the  preceding five years  a 'United  States real  property
holding corporation' for United States federal income tax purposes (assuming the
Common  Stock  is regularly  traded on  an  established securities  market). The
Company believes that it is  not, has at no time  been, and does not  anticipate
becoming  a 'United States real property  holding corporation' for United States
federal income tax purposes. In addition,  the Company believes that the  Common
Stock will be treated as regularly traded on an established securities market.
 
     If the capital gain is effectively connected with the conduct of a trade or
business  of the Non-U.S. Holder within the  United States, or if the Company is
or has  been within  the preceding  five  years a  United States  real  property
holding  corporation  and  the  Non-U.S.  Holder is  more  than  a  five percent
stockholder (applying  certain attribution  rules), the  capital gain  would  be
subject  to regular United States federal  income tax. In addition, with respect
to corporate Non-U.S. Holders, the 'branch profits tax' described above may also
apply. An individual Non-U.S. Holder who is present in the United States for 183
days or more  in the taxable  year of sale  or other disposition  and holds  the
Common  Stock as a capital asset will generally be taxed at a rate of 30% on any
net capital gain recognized  during any year  on such stock  if either (i)  such
individual  has a 'tax  home' (as defined  for United States  federal income tax
purposes) in the United States or (ii) the gain is attributable to an office  or
other fixed place of business maintained by such individual in the United States
and no treaty exemption applies.
 
UNITED STATES INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX
 
     The Company must report annually to the IRS and to each Non-U.S. Holder the
amount  of dividends paid to, and the tax withheld with respect to, such holder.
These information reporting requirements apply regardless of whether withholding
was reduced  or  eliminated  by  an  applicable  tax  treaty.  Copies  of  these
information  returns  may  also be  made  available  under the  provisions  of a
specific treaty or agreement to  the tax authority in  the country in which  the
Non-U.S.  Holder resides.  Under temporary  United States  Treasury regulations,
United States  backup withholding  tax  (which generally  is a  withholding  tax
imposed  at the rate of 31% on certain  payments to persons that fail to furnish
certain information under the United States information reporting  requirements)
and  information reporting with respect to such  tax will generally not apply to
dividends paid on Common Stock  to a Non-U.S. Holder  at an address outside  the
United States.
 
     As a general matter, backup withholding and information reporting also will
not apply to a payment of the proceeds of a sale of Common Stock by or through a
foreign  office of a foreign broker. Information reporting requirements (but not
backup withholding) will apply, however, to a payment of the proceeds of a  sale
of  Common Stock by a foreign office of a broker that is a United States person,
that derives  50% or  more of  its gross  income for  certain periods  from  the
conduct  of a trade or  business in the United States,  or that is a 'controlled
foreign corporation'  (generally, a  foreign  corporation controlled  by  United
States  stockholders) with respect  to the United States,  unless the broker has
documentary evidence in  its records that  the holder is  a Non-U.S. Holder  and
certain  other  conditions  are  met, or  the  holder  otherwise  establishes an
exemption. Payment by a United  States office of a broker  of the proceeds of  a
sale  of  Common Stock  is subject  to both  backup withholding  and information
reporting unless the holder  certifies under penalties of  perjury that it is  a
Non-U.S. Holder, or otherwise establishes an exemption.
 
     Backup  withholding (at a flat 31% rate)  is not an additional tax. Rather,
the tax liability of  persons subject to backup  withholding will be reduced  by
the amount of tax withheld. If withholding results in an overpayment of taxes, a
Non-U.S.  Holder may obtain a refund by  filing the appropriate claim for refund
with the IRS.
 
                                       46
 

<PAGE>
<PAGE>
     These backup withholding and information  reporting rules are under  review
by  the United States Treasury, and their  application to the Common Stock could
be changed  prospectively by  future regulations.  On April  15, 1996,  the  IRS
issued  proposed  Treasury Regulations  concerning  the withholding  of  tax and
reporting for  certain  amounts paid  to  non-resident individuals  and  foreign
corporations. The proposed regulations would, among other changes, eliminate the
presumption  under  current  regulations  with  respect  to  dividends  paid  to
addresses outside  the  United States.  See  'Dividends on  Common  Stock.'  The
proposed  Treasury  Regulations,  if adopted  in  their present  form,  would be
effective for payments made after  December 31, 1997. Prospective purchasers  of
Common Stock should consult their tax advisors concerning the potential adoption
of such Treasury Regulations and the potential effect on the Common Stock.
 
FEDERAL ESTATE TAXES
 
     Common Stock held (or treated as owned) by an individual Non-U.S. Holder at
the  time of  death will be  included in  such holder's gross  estate for United
States federal estate tax purposes and  may be subject to United States  federal
estate  tax, unless an applicable estate  tax treaty provides otherwise. Estates
of non-resident aliens  are generally allowed  a statutory credit  which is  the
equivalent  of  an exclusion  of $60,000  of  assets from  U.S. estate  tax. Tax
treaties may permit a larger credit.

     The  Company has been advised by  the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public at the initial  public
offering  price set forth  on the cover  page hereof, and  to certain dealers at
such initial public offering  price less a selling  concession not in excess  of
$    per share.  The Underwriters  may allow,  and such  dealers may  reallow, a
concession not in excess  of $   per share to certain  other Underwriters or  to
certain  other brokers or dealers. After the initial offering to the public, the
offering price and other selling terms may be changed by the Representatives.
 
     The  Underwriting   Agreement  provides   that  the   obligations  of   the
Underwriters  to  pay for  and accept  delivery  of the  shares of  Common Stock
offered hereby are subject to approval  of certain legal matters by counsel  and
to  certain  other  conditions,  including  the  condition  that  no  stop order
suspending the effectiveness of the Registration  Statement is in effect and  no
proceedings  for such  purpose are pending  or threatened by  the Securities and
Exchange Commission and that  there has been no  material adverse change or  any
development  involving a prospective material adverse change in the condition of
the Company from that set forth in the Registration Statement otherwise than  as
set  forth or  contemplated in this  Prospectus, and  that certain certificates,
opinions and letters have  been received from the  Company and its counsel.  The
Underwriters are obligated to take and pay for all of the above shares of Common
Stock if any such shares are taken.
 
     The  Company and the Underwriters have agreed in the Underwriting Agreement
to indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
     The Company has granted to the Underwriters an option to purchase up to  an
additional   525,000  shares  of  Common  Stock,  exercisable  solely  to  cover
over-allotments, at the  initial public  offering price,  less the  underwriting
discounts  and  commissions shown  on the  cover page  of this  Prospectus. Such
option may  be exercised  at  any time  until  30 days  after  the date  of  the
Underwriting  Agreement.  To  the  extent that  the  option  is  exercised, each
Underwriter will be committed to purchase  a number of the additional shares  of
Common Stock proportionate to each Underwriter's initial commitment as indicated
in the preceding table.
 
     The  Representatives of the Underwriters have informed the Company that the
Underwriters do not intend to confirm sales to accounts over which they exercise
discretionary authority.
 

     For a period of  180 days after  the closing of  the Offering, without  the
written  consent of Lehman  Brothers Inc., the  Company and all  of its existing
stockholders have agreed not to offer, sell or contract to sell, grant any offer
to purchase  or otherwise  dispose of  any  shares of  common stock  other  than
issuance   pursuant  to  employee  compensation   plans,  transfers  among  such
stockholders, pledges, in the case of death or permanent disability and  certain
limited charitable donations.

 
     At the request of the Company, the Underwriters have reserved up to 300,000
shares  of Common Stock for sale at the initial public offering price to certain
of the Company's employees and certain
 
                                       48
 

<PAGE>
<PAGE>

other persons. The number of  shares of Common Stock  available for sale to  the
general  public  will  be reduced  to  the  extent these  persons  purchase such
reserved shares. If such reserved shares are not purchased by such employees and
other persons, they will be offered by  the Underwriters to the public upon  the
same  terms  and conditions  set  forth in  this  Prospectus. Johnson  & Johnson
Development Corporation, an  affiliate of  Johnson & Johnson,  has expressed  an
interest  in purchasing  10% of the  Offering, up  to $6.5 million  worth of the
shares of  Common  Stock offered  hereby,  at  the public  offering  price.  See
'Business -- Corporate and Government Collaborations.'

 
     Prior  to the  Offering, there  has been  no public  market for  the Common
Stock. The initial public offering price was negotiated between the Company  and
the  Representatives. Among  the factors  considered in  determining the initial
public offering price of the Common Stock, in addition to the prevailing  market
conditions,  were  the  Company's  historical  performance,  capital  structure,
estimates of the business  potential and earnings prospects  of the Company,  an
assessment of the Company's management and consideration of the above factors in
relation  to market  values of companies  in related business  and other factors
deemed relevant.
 
                                 LEGAL MATTERS
 

     Certain legal matters in connection with  the Offering will be passed  upon
for the Company by Latham & Watkins. Roger Kimmel, a director of the Company, is
a  partner of Latham & Watkins and his  spouse, Inez Kimmel, and two trusts that
have been established  for the benefit  of Mr. and  Mrs. Kimmel's children,  own
shares  of the Common Stock. See  'Principal Stockholders.' In addition, certain
other partners of Latham & Watkins, in the aggregate, own less than 2.0% of  the
Common  Stock. Certain  legal matters  in connection  with the  Offering will be
passed upon for the Underwriters by Kramer, Levin, Naftalis & Frankel.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Directors and Stockholders
ALGOS PHARMACEUTICAL CORPORATION:
 
     We  have audited  the accompanying  balance sheets  of Algos Pharmaceutical
Corporation (a development stage enterprise) as  of December 31, 1995 and  1994,
and  the related statements  of operations, stockholders'  equity and cash flows
for each  of the  three  years in  the period  ended  December 31,  1995.  These
financial  statements are  the responsibility  of the  Company's management. Our
responsibility is to express an opinion  on these financial statements based  on
our audits.
 
     We  conducted  our audits  in accordance  with generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In  our opinion, the financial statements referred to above present fairly,
in all  material  respects,  the  financial  position  of  Algos  Pharmaceutical
Corporation  as of December 31, 1995 and  1994 and the results of its operations
and its cash flows for each of the three years in the period ended December  31,
1995, in conformity with generally accepted accounting principles.

                        (A DEVELOPMENT STAGE ENTERPRISE)
 (INFORMATION RELATING TO THE SIX MONTHS ENDED JUNE 30, 1995 AND JUNE 30, 1996
            AND CUMULATIVE FROM THE DATE OF INCEPTION IS UNAUDITED)

 
                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION
 
     Algos  Pharmaceutical Corporation (the 'Company'),  is engaged primarily in
the development of proprietary pain management pharmaceuticals.
 
     Since its formation in January 1992, the Company has devoted a  substantial
portion  of  its efforts  to developing  products, licensing  technology, filing
regulatory applications  and  raising  capital and  has  earned  no  significant
revenue from its planned principal operations.
 
     The  Company is subject to a number of risks common to companies in similar
stages of development including,  but not limited to,  the lack of assurance  of
successful  product development,  the absence  of manufacturing  facilities, the
need  to  raise   substantial  additional  funds   and  risk  of   technological
obsolescence.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
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 and
disclosure of contingent assets  and liabilities at the  dates of the  financial
statements  and  the  reported  amounts  of  revenues  and  expenses  during the
reporting periods. Actual results could differ from those estimates.
 
DEVELOPMENT STAGE ENTERPRISE
 
     The accompanying  statements  have been  prepared  in accordance  with  the
provisions   of  Statement  of  Financial  Accounting  Standard  (SFAS)  No.  7,
'Accounting and Reporting by Development Stage Enterprises.'
 
CASH AND CASH EQUIVALENTS
 
     The Company considers securities with  maturities of three months or  less,
when purchased, to be cash equivalents.
 
PROPERTY AND EQUIPMENT, NET
 
     Property  and equipment are recorded at cost less accumulated depreciation.
Depreciation is provided on the  straight-line method over the estimated  useful
lives  of the assets which range from three  to seven years. Gains and losses on
depreciable assets retired or sold are recognized in the statement of operations
in the year of  disposal. Repairs and maintenance  expenditures are expensed  as
incurred.
 

REVENUE

 

     License  fees are recognized as revenue  when earned in accordance with the
terms of the underlying agreements.

                        (A DEVELOPMENT STAGE ENTERPRISE)
 (INFORMATION RELATING TO THE SIX MONTHS ENDED JUNE 30, 1995 AND JUNE 30, 1996
            AND CUMULATIVE FROM THE DATE OF INCEPTION IS UNAUDITED)

 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
RESEARCH AND DEVELOPMENT COSTS
 
     Expenditures for research and development are expensed as incurred.
 
INCOME TAXES
 
     The Company accounts for income taxes under the provisions of SFAS No. 109,
'Accounting for Income Taxes.' SFAS No. 109 requires recognition of deferred tax
assets and liabilities  for the  expected future tax  consequences of  temporary
differences  between  the  financial  statement  and  tax  bases  of  assets and
liabilities using  enacted  tax rates  in  effect for  the  years in  which  the
differences are expected to reverse.
 
STOCK BASED COMPENSATION
 
     In  October 1995, the Financial Accounting  Standards Board issued SFAS No.
123, 'Accounting for Stock Based Compensation.' Beginning in 1996, SFAS No.  123
requires  expanded  disclosures  of stock-based  compensation  arrangements with
employees and  encourages, but  does not  require, the  recognition of  employee
compensation  expense related to  stock compensation based on  the fair value of
the equity  instrument granted.  Companies  that do  not  adopt the  fair  value
recognition  provisions of SFAS No. 123 and  continue to follow the existing APB
Opinion 25 rules  to recognize  and measure  compensation, will  be required  to
disclose  the pro forma amounts of net  income and earnings per share that would
have been reported had the company elected to follow the fair value  recognition
of SFAS No. 123. The Company has elected to adopt the disclosure requirements of
this pronouncement.
 
EARNINGS PER SHARE
 

     Pro  forma net  loss per  common share  is based  on the  net loss  and the
weighted average number of common shares  after giving effect to the  conversion
of  all  preferred stock  as  of January  1,  1995. Pursuant  to  Securities and
Exchange Commission  Staff Accounting  Bulletin No.  83, all  common shares  and
stock options and warrants granted by the Company during the twelve months prior
to  the filing  date of  the Registration  Statement have  been included  in the
calculation of  weighted  average common  shares  and common  share  equivalents
outstanding  as if they were outstanding  for all periods presented. Outstanding
stock options and warrants  granted prior to this  twelve-month period have  not
been included in the calculation of historical net loss per common share because
inclusion of such shares would be antidilutive.

 
     Historical net loss per common share is as follows:

6. INCOME TAXES
 
     Prior to March  1, 1994,  the Company  had elected to  be treated  as an  S
Corporation  for federal income tax reporting purposes. Under this election, the
Company's stockholders  were responsible  for  reporting the  Company's  federal
taxable  loss on their personal tax returns.  In connection with the issuance of
Series A Preferred Stock, the Company's S status terminated and the  corporation
converted  to C Corporation status.  The C Corporation assumed  the tax bases of
the assets and  liabilities of  the S Corporation  as of  the termination  date.
Accordingly,  the Company  records deferred taxes  for the  effect of cumulative
temporary differences  in  accordance  with  the provisions  of  SFAS  No.  109,
'Accounting  for Income  Taxes' for federal  tax purposes as  of the termination
date. For state tax purposes,  the Company has been  treated as a C  Corporation
since inception.

     At  December  31,  1995,  the  Company  had  available  net  operating loss
carryforwards and  research  and  development credits  for  federal  income  tax
purposes  of approximately $2,997,000 and $70,000, respectively, which expire in
the years 2009 through  2010. At June  30, 1996, the  Company had available  net
operating loss carryforwards of approximately $2,100,000. Due to the uncertainty
of  their realization, no income tax benefits  have been recorded by the Company
for these net  operating loss  or credit carryforwards  as valuation  allowances
have been established for any such benefits. The use of these net operating loss
and  credit carryforwards may be subject to limitations under section 382 of the
Internal Revenue Code pertaining to changes in stock ownership.

 
     The increase in the valuation  allowance amounted to $406,100 and  $906,300
in 1994 and 1995, respectively.

     On  May  21,  1996, the  Board  of  Directors authorized  the  filing  of a
registration statement with the Securities and Exchange Commission for the  sale
of  Common  Stock. If  the offering  pursuant to  the registration  statement is
consummated under the terms  presently anticipated, all shares  of the Series  A
Preferred  Stock will convert  to Common Stock and  the Preferred Stock warrants
will convert  to  Common  Stock  warrants. The  Series  A  Preferred  Stock  and

consummated upon the effective date of the registration statement. In  addition,
upon  the closing of the initial public  offering, the total number of shares of
preferred stock authorized will be 10,000,000 par value $.01. All references  to

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
10. RELATED PARTY TRANSACTION
 

     A  director of the Company has been associated with law firms that rendered
various legal services to  the Company. The  Company paid approximately  $3,000,
$95,000  and $16,000 in 1993,  1994 and 1995, respectively,  and $22,000 for the
six months  ended June  30, 1996,  and $165,000  cumulatively from  the date  of
inception, for these services.

 

     A  second director  of the Company,  appointed in July  1996, is associated
with a law firm which performs legal services for the Company from time to time.
The Company  paid approximately  $0, $68,000  and  $0 in  1993, 1994  and  1995,
respectively,  and $68,000  cumulatively from  the date  of inception  for these
services and has accrued approximately $217,000 for services rendered in the six
months ended June 30, 1996, primarily related to the initial public offering.

 

11. SUBSEQUENT EVENT (UNAUDITED) -- TRANSFER OF INTANGIBLE ASSETS

 

     In August 1996, the Company contributed certain intangible assets having no
book value  to  PharmaDyn,  Inc.  ('PharmaDyn'), a  newly  formed  company,  and
received  preferred stock with an aggregate par value and liquidation preference
of $2,800,000  and  all  of  PharmaDyn's common  stock.  The  common  stock  was
subsequently  distributed  to the  Company's  stockholders, warrant  holders and
certain of its employees. The preferred stock provides for an annual  cumulative
dividend  of 30% which may be paid in the form of cash or PharmaDyn common stock
and a share of other earnings. The  preferred stock may be redeemed at any  time
for par plus accrued dividends at PharmaDyn's option and at the Company's option
at  the end of  two years. The Company  recorded no gain  in connection with the
transactions as management believes that at the present time realization of  the
redemption value is not assured.

*  To be filed by amendment.
 
ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 

     Section 145  of  the Delaware  General  Corporation Law  (the  'DGCL')  and
Article SEVENTH of the Amended and Restated Certificate of Incorporation provide
for  indemnification of  the Company's  directors and  officers in  a variety of
circumstances, which may include liabilities  under the Securities Act of  1933,
as  amended  (the  'Securities  Act').  Article  SEVENTH  provides  that  unless
otherwise determined by the Board of Directors, the Company shall indemnify,  to
the  full extent  permitted by  the laws  of Delaware  as from  time to  time in
effect, the persons described in Section 145 of DGCL.

 

     The  general  effect  of  the  provisions  in  the  Amended  and   Restated
Certificate  of Incorporation and the DGCL is  to provide that the company shall
indemnify its  directors  and  officers against  all  liabilities  and  expenses
actually and reasonably incurred in connection with the defense or settlement of
any judicial or administrative proceedings in which they have become involved by
reason of their status as corporate directors or officers, if they acted in good
faith  and in the reasonable belief that  their conduct was neither unlawful (in
the case of criminal  proceedings) nor inconsistent with  the best interests  of
the Company. With respect to legal proceedings by or in the right of the Company
in  which a director or  officer is adjudged liable  for improper performance of
his duty to the Company or another enterprise for which such person served in  a
similar  capacity at the  request of the Company,  indemnification is limited by
such provisions to that amount which is permitted by the court.

 
     Reference is made to the proposed  form of Underwriting Agreement filed  as
Exhibit  1.1 which provides for indemnification of the directors and officers of
the Company signing the Registration  Statement and certain controlling  persons
of  the Company against certain liabilities, including certain liabilities under
the Securities Act, by the Underwriters.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     During the past  three years,  the following  securities were  sold by  the
Company without registration under the Securities Act:
 

          Pursuant  to Subscription and Stock  Purchase Agreements, dated May 9,
     June 30, July  15, August 12  and August  22, 1994, the  Company issued  70
     Units,  each Unit consisting of 10,000  shares of Series A Preferred Stock,
     $.01 par value, of the Company to management, certain existing stockholders
     and a limited number of other investors for an aggregate purchase price  of
     $7,000,000  in a  transaction that was  exempt from  registration under the
     Securities Act pursuant to Regulation D under the Securities Act.

          On June 27, 1996,  the Company issued 100,000  shares of its Series  B
     Preferred  Stock to  The Medical  College of  Virginia in  consideration of
     certain amendments  to its  license  agreement in  a transaction  that  was
     exempt  from registration under the Securities Act pursuant to Section 4(2)
     thereof.

 

          On July 18, 1994,  November 10, 1995, March  22, 1996, April 1,  1996,
     and  July 2,  1996 the Company  issued options to  purchase 772,730 shares,
     24,900  shares,   52,290  shares,   190,900  shares   and  10,000   shares,

     Plan,  1996 Stock Option  Plan and 1996  Non-Employee Director Stock Option
     Plan  in  transactions  that  were  exempt  from  registration  under   the
     Securities Act pursuant to Section 4(2) thereof.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at  the closing  specified in the  Underwriting Agreement,  certificates in such
denominations and registered in  such names as required  by the Underwriters  to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of  1933 may be permitted to directors,  officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or
 
                                      II-2
 
<PAGE>
<PAGE>
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange  Commission,  such  indemnification is  against  public  policy  as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification against  such liabilities  (other than  the payment  by the
Registrant of expenses incurred  or paid by a  director, officer or  controlling
person  of  the Registrant  in the  successful  defense of  any action,  suit or
proceeding) is  asserted by  such  director, officer  or controlling  person  in
connection  with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, 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 Registrant pursuant to Rule 424(b)(1)  or
     (4) or 497(h) under the Securities Act shall be deemed to be a part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For purposes of determining any liability under the Securities Act
     of  1933, each post-effective amendment that  contains a form of Prospectus
     shall be  deemed  to  be  a new  registration  statement  relating  to  the
     securities  offered therein,  and the offering  of such  securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 

     The undersigned Registrant hereby undertakes to provide to the  underwriter
at  the closing  specified in  the underwriting  agreement certificates  in such
denominations and registered in  such names as required  by the underwriters  to
permit prompt delivery to each purchaser.

 
     Insofar as indemnification for liabilities arising under the Securities Act
of  1933 may be permitted to directors,  officers and controlling persons of the
Registrant pursuant to  the foregoing provisions,  or otherwise, the  Registrant
has  been advised that in the opinion  of the Securities and Exchange Commission
such indemnification is against  public policy as expressed  by the Act and  is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses  incurred
or  paid by a director,  officer or controlling person  of the Registrant in the
successful defense  of any  action,  suit or  proceeding)  is asserted  by  such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled  by controlling  precedent, submit  to a  court of  appropriate
jurisdiction  the question whether such indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned Registrant hereby undertakes that:
 

          (1) For purposes of determining any liability under the Securities Act
     of 1933, 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 Registrant pursuant to Rule 424(b)(1)  or
     (4)  or 497(h) under the Securities Act shall  be deemed to be part of this
     Registration Statement as of the time it was declared effective.

 

          (2) For the purpose of determining any liability under the  Securities
     Act  of  1933,  each  post-effective  amendment  that  contains  a  form of
     Prospectus shall be deemed to be  a new registration statement relating  to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

                                   ARTICLE III
                                    PURPOSES

        The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the GCL.


                                   ARTICLE IV
                                CAPITAL STRUCTURE

        The total number of shares of stock which the Corporation shall have
authority to issue is sixty million (60,000,000) divided into fifty million
(50,000,000) shares of common stock, of the par value of $0.01 per share (the
"Common Stock"), and ten million (10,000,000) shares of preferred stock, of the
par value of $0.01 per share (the "Preferred Stock").

        The Board of Directors of the Corporation is authorized, subject to
limitations prescribed by law and the provisions of this Article IV, to provide
for the issuance of the shares of Preferred Stock in series, and by filing a
certificate pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, and to fix the designation, powers, privileges, preferences and rights
of the shares of each such series and the qualifications, limitations or
restrictions thereof.

        The authority of the Board of Directors of the Corporation with respect
to each series shall include, but not be limited to, determination of the
following:

               (a)    The number of shares constituting that series and the 
distinctive designation of that series;

               (b) The dividend rate on the shares of that series, whether
dividends shall be cumulative, and, if so, from which date or dates, and the
relative rights of priority, if any, of payment of dividends on shares of that
series;

               (c) Whether that series shall have voting rights, in addition to
the voting rights provided by law, and, if so, the terms of such voting rights,
[provided that no series of Preferred Stock shall have a class vote unless the
same has been approved in writing by the holders of at least a majority of the
outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors];

               (d) Whether that series shall have conversion privileges, and, if
so, the terms and conditions of such conversion, including provision for
adjustment of the conversion rate in such events as the Board of Directors shall
determine;

               (e) Whether or not the shares of that series shall be redeemable,
and, if so, the terms and conditions of such redemption, including the date or
dates upon or after which they shall be redeemable, and the amount per share
payable in case of redemption, which amount may vary under different conditions
and at different redemption dates;



                                             3

<PAGE>
<PAGE>



               (f) Whether that series shall have a sinking fund for the
redemption or purchase of shares of that series, and, if so, the terms and
amount of such sinking fund;

               (g) The rights of the shares of that series in the event of
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, and the relative rights of priority, if any, of payment of shares
of that series; and

               (h)    Any other relative rights, preferences and limitations of
that series.

        Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the Common Stock with respect to the same
dividend period.

        If upon any voluntary or involuntary liquidation, dissolution or winding
up of the Corporation, the assets available for distribution to holders of
shares of Preferred Stock of all series shall be insufficient to pay such
holders the full preferential amount to which they are entitled, then such
assets shall be distributed ratably among the shares of all series of Preferred
Stock in accordance with the respective preferential amounts (including unpaid
cumulative dividends, if any) payable with respect thereto.


                                    ARTICLE V
                                  VOTING RIGHTS

        Subject to the voting rights provided by law or granted to any series of
Preferred Stock, all rights to vote and all voting power shall be exclusively
vested in the Common Stock.


                                   ARTICLE VI
                  STOCKHOLDER ACTION AND THE BOARD OF DIRECTORS

        Any action required or permitted to be taken by stockholders of the
Corporation must be effected at a duly called annual or special meeting of
stockholders and may not be effected by a consent in writing. Special meetings
may be called only by the Chairman of the Board or the President of the
Corporation or by the majority of the whole Board of Directors.

        The number of directors constituting the entire Board of Directors of
the Corporation shall be fixed by, or in the manner provided in, the
Corporation's By-Laws from time to time.


                                   ARTICLE VII
                                     BYLAWS

        In furtherance and not in limitation of the powers conferred by the laws
of the State of Delaware, a majority of the entire Board of Directors of the
Corporation is expressly authorized to make, alter and repeal from time to time
the By-Laws of the Corporation, subject to the power of the


                                             4

stockholders  of the Corporation to alter or repeal any by-law made by the Board
of Directors of the Corporation.


                                  ARTICLE VIII
                              BUSINESS COMBINATIONS

        In addition to any affirmative vote required by law, and except as
otherwise expressly provided in section (b) of this Article, any business
combination (as hereinafter defined) shall require the affirmative vote of the
holders of at least 66 2/3% of the outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors, considered
for the purpose of this Article as one class ("Voting Shares"). Such affirmative
vote shall be required (unless subsection (b)(A) or (b)(B) of this Article
applies) notwithstanding the fact that no vote may be required, or that some
lesser percentage may be specified, by law or in any agreement with any national
securities exchange or otherwise.

               (a) 1. The term "business combination" as used in this Article
shall mean any transaction which is referred to in any one or more of the
following clauses (A) through (E):

                     (A) any merger or  consolidation of the  Corporation or any
Subsidiary (as hereinafter defined) with or into (i) any Interested  Stockholder
(as hereinafter defined) or (ii) any other corporation (whether or not itself an
Interested  Stockholder) which, after such merger or consolidation,  would be an
Affiliate (as hereinafter defined) of an Interested Stockholder, or

                      (B) any sale, lease, exchange, mortgage, pledge, transfer
or other disposition (in one transaction or a series of related transactions) to
or  with  any  Interested   Stockholder  or  any  Affiliate  of  any  Interested
Stockholder  of any  assets  of the  Corporation  or any  Subsidiary  having  an
aggregate  fair market value of more than twenty five percent  (25%) of the Fair
Value (as hereinafter  defined) of the shares of Common Stock of the Corporation
outstanding immediately prior to such transaction, or

                      (C) the  issuance or transfer by the  Corporation  or any
Subsidiary  (in one  transaction  or a series of  related  transactions)  of any
securities of the Corporation or any Subsidiary to any Interested Stockholder or
any Affiliate of any Interested  Stockholder in exchange for cash, securities or
other property (or a combination  thereof) having an aggregate fair market value
of more than  twenty-five  (25%) of the Fair Value of the shares of Common Stock
of the Corporation outstanding immediately prior to such transaction, or

                       (D)  the  adoption  of  any  plan  or  proposal  for  the
liquidation  or dissolution  of the  Corporation  proposed by or on behalf of an
Interested  Stockholder  or any Affiliate of an Interested  Stockholder,  except
that  this  provision  shall  not  limit  the  right  of  stockholders  to elect
voluntarily to wind up or dissolve the Corporation, or

                       (E) any  reclassification  of securities  (including  any
reverse stock split), or recapitalization  of the Corporation,  or any merger or
consolidation  of the  Corporation  with any of its  Subsidiaries or any similar
transaction  (whether or not with or into or otherwise  involving an  Interested
Stockholder)  which has the effect,  directly or  indirectly,  of increasing the
proportionate


                                             5

share of the outstanding shares of any class of equity securities of the
Corporation or any Subsidiary or any class of securities exchangeable for or
convertible into any such class of equity securities of the Corporation or any
Subsidiary which is directly or indirectly owned by any Interested Stockholder
or any Affiliate of any Interested Stockholder.

               (b) A business combination shall not be subject to the provisions
of section (a) of this Article, and shall require only such affirmative vote as
is required by law, if either:

                            (A) the business  combination has been approved by a
majority of the whole Board of Directors of the Corporation; or

                            (B) the aggregate amount of the cash and fair market
value of  consideration  other than cash to be received  per share by holders of
Common Stock in such business combination shall be at least equal to the highest
of the following:

                       (i) the  highest  per share  price  (including  brokerage
commissions,   transfer  taxes  and  soliciting  dealers'  fees)  paid  by  such
Interested  Stockholder for any shares of Common Stock acquired by it within the
two-year period prior to the business combination;

                       (ii) the Fair  Value  per  share of  Common  Stock on the
Determination Date for such business combination; and

                       (iii) the Fair  Value  per  share of Common  Stock on the
Announcement Date of such business combination.

               (c)    For the purposes of this Article:

                       1.  A   "person"   shall  mean  any   individual,   firm,
corporation or other entity.

                       2. "Interested Stockholder" shall mean, in respect of any
business combination,  any person (other than the Corporation or any Subsidiary)
who or  which,  as of the  record  date for the  determination  of  stockholders
entitled to notice of and to vote on such business  combination,  or immediately
prior to the consummation of any such transaction:

                            (A) is the beneficial owner, directly or indirectly,
of more than 10% of the Voting Shares, or

                            (B) is an  Affiliate of the  Corporation  and at any
time  within two years  prior  thereto  was the  beneficial  owner,  directly or
indirectly, of not less than 10% of the then outstanding Voting Shares, or

                            (C) is an assignee of or has otherwise  succeeded to
any shares of capital stock of the Corporation which were at any time within two
years prior thereto  beneficially  owned by any Interested  Stockholder,  unless
such  assignment  or succession  shall have occurred in a transaction  that is a
public offering within the meaning of the Securities Act of 1933, as amended.

                       3. A  "person"  shall be the  "beneficial  owner"  of any
Voting Shares:

under the  Securities  Exchange Act of 1934 as in effect on the date of adoption

                       6. "Subsidiary"  shall mean any  corporation  of which a

for all purposes.

               (e) Nothing contained in this Article shall be construed to

                                   ARTICLE IX
              INDEMNIFICATION AND EXCULPATION OF DIRECTOR LIABILITY

        Each person who was or is made a party or is threatened to be made a
party to or is involved in any action, suit or proceeding, whether civil,
criminal, administrative or investigative (hereinafter a "proceeding"), by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or is or was
serving at the request of the Corporation as a director or officer of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans, whether the basis of
such proceeding is alleged action in an official capacity as a director or
officer or in any other capacity while serving as a director or officer, shall
be indemnified and held harmless by the Corporation to the fullest extent
permitted by Delaware law as the same exists or may hereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than said law
permitted the Corporation to provide prior to such amendment), against all
expense, liability and loss (including attorneys fees, judgments, fines, excise
taxes or penalties and amounts paid or to be paid in settlement) reasonably
incurred or suffered by such person in connection therewith and such
indemnification shall continue as to a person who has ceased to be a director or
officer and shall inure to the benefit of his or her


                                             8

heirs, executors and administrators; provided, however, that except as provided
below, the Corporation shall indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person only
if such proceeding (or part thereof) was authorized by the Board. The right to
indemnification conferred in this paragraph shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that, if the GCL requires the payment of such expenses incurred by a
director or officer in his or her capacity as a director or officer (and not in
any other capacity in which service was or is rendered by such person while a
director or officer, including, without limitation, service to an employee
benefit plan) in advance of the final disposition of a proceeding, such payment
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such director or officer, to repay all amounts so advanced if it shall
ultimately be determined that such director or officer is not entitled to be
indemnified under this paragraph or otherwise.

        If a claim under the preceding paragraph of this Article is not paid in
full by the Corporation within 90 days after a written claim has been received
by the Corporation, the claimant may at any time thereafter bring suit against
the Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expense of
prosecuting such claim. It shall be a defense to any such action (other than an
action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its final disposition where the required undertaking,
if any is required, has been tendered to the Corporation) that the claimant has
not met the standards of conduct which make it permissible under the GCL for the
Corporation to indemnify the claimant for the amount claimed. Neither the
failure of the Corporation (including any required action by directors,
independent legal counsel, or stockholders) to have made a determination prior
to the commencement of such action that indemnification of the claimant is
proper in the circumstances because he or she has met the applicable standard of
conduct set forth in the GCL, nor an actual determination by the Corporation
(including any required action by directors, independent legal counsel, or
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that the claimant has
not met the applicable standard of conduct.

        The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Article shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaw, agreement, vote of stockholders or disinterested directors
or otherwise.

        The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee or agent of the Corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such expense, liability or
loss under the GCL.

        A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation and its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) for unlawful payments of dividends or unlawful stock
repurchases or redemptions, as provided in Section 174 of the GCL, or (iv) for
any transaction from which the director derived any improper


                                             9

<PAGE>



personal benefit. If the GCL is amended to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the GCL, as so amended. Any repeal or modification of this
paragraph by the stockholders of the Corporation shall not adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification.

                                    ARTICLE X
                                   AMENDMENTS

     The Corporation reserves the right at any time, and from time to time,
to amend, alter, change or repeal any provision contained in this Amended and
Restated Certificate of Incorporation, 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 now or hereafter prescribed by law; and all rights, preferences and
privileges of whatsoever nature conferred upon stockholders, directors or any
other persons whomsoever by and pursuant to this Amended and Restated
Certificate of Incorporation in its present form or as hereafter amended are
granted subject to the rights reserved in this article provided, however, that
amendment or repeal of Articles VI, IX and this Article X, and any reduction of
the number of authorized shares of Common Stock and Preferred Stock requires the
affirmative vote of the holders of at least 662/3% of the outstanding voting
stock of the Corporation.

        purpose other than those specified in Sections 2.4.1 and 2.4.2 shall be
        at the close of business on the day on which the Board of Directors
        adopts the resolution relating thereto.

When a determination of stockholders entitled to notice of or to vote at any
meeting of stockholders has been made as provided in this Section 2.4, such
determination shall apply to any adjournment thereof, unless the Board of
Directors fixes a new record date for the adjourned meeting.

               SECTION 2.5.  NOTICE OF MEETINGS OF STOCKHOLDERS.
        At any meeting of the stockholders, only such business
(including the nomination of persons for election as directors as described
below) shall be conducted as shall have been properly brought before the
meeting. To be properly brought before a meeting, business must be (a) specified
in the notice of meeting (or any supplement thereto) given by or at the
direction of the Board of Directors, (b) otherwise properly brought before the


                                        2

<PAGE>



meeting by or at the direction of the Board of Directors, or (c) otherwise
properly brought before the meeting by a stockholder. For business to be
properly brought before a meeting by a stockholder, the stockholder must have
given timely notice thereof in writing to the Secretary of the Corporation. In
the case of an annual meeting, to be timely, a stockholder's notice shall be
delivered to and received by the Secretary of the Corporation at the principal
executive offices of the Corporation not less than 60 days nor more than 90 days
prior to the meeting; provided, however, that in the event that less than 70
days' notice or prior public disclosure of the date of the meeting is given or
made to stockholders, notice by the stockholder to be timely must be so received
no later than the close of business on the tenth day following the day on which
such notice of the date of the meeting was mailed or such public disclosure was
made. In the case of a special meeting, to be timely, a stockholder's notice
must be delivered not more than ninety days prior to the special meeting and not
later than the later of sixty days prior to the special meeting and ten days
following the day on which public announcement of the meeting is first made by
the Corporation.

               A stockholder's notice to the Secretary shall set forth as to
each matter the stockholder proposes to bring before the annual meeting (a) a
brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (b)
the name and address, as they appear on the Corporation's books, of the
stockholder proposing such business, (c) the class and number of shares of the
Corporation which are beneficially owned by the stockholder and (d) any material
interest of the stockholder in such business. Notwithstanding anything in the
By-Laws to the contrary, no business shall be conducted at an annual meeting
except in accordance with the procedures set forth in this Section 2.5.

               In the case of nominations of persons for election as directors,
only persons who are nominated in accordance with the following procedures shall
be eligible for election as directors. Nominations of persons for election to
the Board of Directors of the Corporation may be made at a meeting of
stockholders (i) by or at the direction of the Board of Directors, (ii) by any
nominating committee or person appointed to make such nominations by the Board
of Directors, or (iii) by any stockholder of the Corporation entitled to vote
for the election of directors at the meeting who complies with the notice
procedures set forth in this Section 2.5. Such nominations, if made by a
stockholder of the Corporation as such, shall be made pursuant to timely notice
(as described in the first paragraph of this Section 2.5) in writing addressed
to the Secretary of the Corporation. Such stockholder's notice shall set forth:
(a) as to each person whom the stockholder proposes to nominate for election or
re-election as a director (i) the name, age, business address and residence
address of the person, (ii) the principal occupation or


                                        3


<PAGE>
<PAGE>



employment of the person, (iii) the class and number of shares of stock of the
Corporation which are beneficially owned by the person and (iv) any other
information relating to the person that would be required to be disclosed in
solicitations for proxies for the election of directors pursuant to Regulation
14A under the Securities Exchange Act of 1934, as amended, or any successor
thereto, and (b) as to the stockholder giving the notice (i) the name and record
address of the stockholder and (ii) the class and number of shares of the
Corporation which are beneficially owned by the stockholder. The Corporation may
require any proposed nominee to furnish such other information as may reasonably
be required by the Corporation to determine the eligibility of such proposed
nominee to serve as a director of the Corporation. No person shall be eligible
for election as a director of the Corporation unless nominated in accordance
with the procedures set forth herein.

               The presiding officer of an annual meeting shall, if the facts
warrant, determine and declare to the meeting that business or a nomination of a
director was not properly brought before the meeting in accordance with this
Section 2.5, and if the presiding officer should so determine, the presiding
officer shall so declare to the meeting and say such business not properly
brought before the meeting shall not be transacted or that the defective
nomination shall be disregarded.

               SECTION 2.6. WAIVERS OF NOTICE. Whenever notice is required to be
given to the stockholders under any provision of the General Corporation Law of
the State of Delaware (the "GCL") or the Amended and Restated Certificate of
Incorporation (the "Certificate of Incorporation") or the By-laws, a written
waiver thereof, signed by a stockholder entitled to notice, whether before or
after the time stated therein, shall be deemed equivalent to notice. Attendance
of a stockholder at a meeting shall constitute a waiver of notice of such
meeting, except when the stockholder 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 stockholders need be specified in any written waiver of notice.

               [SECTION 2.7.] LIST OF STOCKHOLDERS. The Secretary shall prepare
and make, or cause to be prepared and made, at least ten days before every
meeting of stockholders, a complete 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
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified, or at the place where the
meeting is to be held. The list shall also be


                                        4


<PAGE>
<PAGE>



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.

               SECTION 2.8. QUORUM OF STOCKHOLDERS; ADJOURNMENT. The holders of
a majority of the shares of stock entitled to vote at any meeting of
stockholders, present in person or represented by proxy, shall be necessary and
sufficient to constitute a quorum for the transaction of any business at such
meeting, except where otherwise provided by the GCL. When a quorum is once
present to organize a meeting of stockholders, it is not broken by the
subsequent withdrawal of any stockholder. The holders of a majority of the
shares of stock present in person or represented by proxy at any meeting of
stockholders, including an adjournment meeting, whether or not a quorum is
present, may adjourn such meeting to another time and place.

               SECTION 2.9. VOTING; PROXIES. Unless otherwise provided in the
Certificate of Incorporation, every stockholder of record shall be entitled at
every meeting of stockholders to one vote for each share of capital stock
standing in his name on the record of stockholders determined in accordance with
Section 2.4 of the By-laws. If the Certificate of Incorporation provides for
more or less than one vote for any share on any matter, every reference in the
By-laws or the GCL to a majority or other proportion of stock shall refer to
such majority to other proportion of the votes of such stock. The provisions of
Sections 212 and 217 of the GCL shall apply in determining whether any shares of
capital stock may be voted and the persons, if any, entitled to vote such
shares; but the Corporation shall be protected in treating the persons in whose
names shares of capital stock stand on the record of stockholders as owners
thereof for all purposes. Directors shall be chosen by a plurality of the votes
cast at the election and each other matter, except as otherwise provided by law
or by the Certificate of Incorporation or by the By-laws, shall be decided by a
majority of the votes cast on such matter. All elections of directors shall be
by written ballot unless otherwise provided in the Certificate of Incorporation.
In voting on any other question on which a vote by ballot is required by law or
is demanded by any stockholder entitled to vote, the voting shall be by ballot.
Each ballot shall be signed by the stockholder voting or by his proxy, and shall
state the number of shares voted. On all other questions, the voting may be by
voice vote. Every stockholder entitled to vote at a meeting of stockholders or
to express consent or dissent to corporate action in writing without a meeting,
may authorize another person or persons to act for him by proxy. The validity
and enforceability of any proxy shall be determined in accordance with Section
212 of the GCL.

               SECTION 2.10. SELECTION AND DUTIES OF INSPECTORS AT MEETING OF
STOCKHOLDERS. The Board of Directors, in advance of any meeting of stockholders,
may appoint one or more inspectors to act at the meeting or any adjournment
thereof. If inspectors


                                        5


<PAGE>
<PAGE>



are not so appointed, the person presiding at such meeting may, and on the
request of any stockholder entitled to vote thereat shall, appoint one or more
inspectors. In case any person appointed fails to appear or act, the vacancy may
be filled by appointment made by the Board of Directors in advance of the
meeting or at the meeting by the person presiding thereat. Each inspector,
before entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspector at such meeting with strict
impartiality and according to the best of his ability. The inspector or
inspectors shall determine the number of shares outstanding and the voting power
of each, the shares represented at the meeting, the existence of a quorum, the
validity and effect of proxies, and shall receive votes, ballots or consents,
count and tabulate all votes, ballots or consents, hear and determine all
challenges and questions arising in connection with the right to vote, determine
the result, and shall 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 or any stockholder entitled to vote thereat, the inspector or inspectors
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. Any
report or certificate made by the inspector or inspectors shall be prima facie
evidence of the facts stated and of the vote as certified by him or them.

               SECTION 2.11. ORGANIZATION. At every meeting of stockholders, the
President, or in the absence of the President, a Vice President, and in case
more than one Vice President shall be present, that a Vice President designated
by the Board of Directors (or in the absence of any such designation, the most
senior Vice President, based on age, present), shall act as chairman of the
meeting. At every meeting of stockholders, the Secretary, or in the absence of
the Secretary, an Assistant Secretary, shall act as secretary of the meeting. In
case none of the officers above designated to act as chairman or secretary of
the meeting, respectively, shall be present, a chairman or a secretary of the
meeting, as the case may be, may be chosen by a majority of the votes case at
such meeting by the holders of shares present in person or represented by proxy
and entitled to vote at the meeting.

               SECTION 2.12. ORDER OF BUSINESS. The order of business at all
meetings of stockholders shall be as determined by the chairman of the meeting,
but,the order of business to be followed at any meeting at which a quorum is
present may be changed by a majority of the votes cast at such meeting by the
holders of shares of capital stock present in person or represented by proxy and
entitled to vote at the meeting.

annual stockholders' meeting, the Board of Directors shall be divided into three
classes, with one class having an initial term of one year, one class having an
initial term of two years and one class having a term of three years. At each
annual meeting of stockholders, directors will be elected to succeed those
directors whose terms have expired, and each newly elected director will serve
for a three-year term. All directors elected to the Company's classified Board
of Directors will serve until the election and qualification of their successors
or their earlier resignation or removal.

               SECTION 3.2. RESIGNATIONS. Any director, member of a committee or
other officer may resign at any time. Such resignation shall be made in writing,
and shall take effect at the time specified therein, and if no time be
specified, at the time of its receipt by the President or Secretary. The
acceptance of a resignation shall not be necessary to make it effective.

               SECTION 3.3. VACANCIES. If the office of any director, member of
a committee or other officer becomes vacant for any reason (whether resulting
from an increase in the number of directors, resignation, removal or otherwise),
the remaining directors in office, though less than a quorum, by a majority
vote, may appoint any qualified person to fill such vacancy, who shall hold
office for the remainder of the term of the directorship in which the vacancy
occurred.

               SECTION 3.4. REMOVAL. Upon classification of the Board of
Directors at the Corporation's 1996 annual meeting, a director or directors may
be removed only for cause, in any event, by the affirmative vote of the holders
of a majority of all the shares of stock outstanding and entitled to vote, at a
special meeting of the stockholders called for that purpose.

               SECTION 3.5. INCREASE OR DECREASE OF NUMBER. By the affirmative
vote of a majority of the directors, though less than a quorum, the Board of
Directors is authorized to create new directorships and to fill such positions
so created and is permitted to specify the class to which such new position is
assigned, and the person filing such position shall serve for the term
applicable to that class. Any newly created directorship may be filled in the
same manner as a vacancy.

               SECTION 3.6. POWERS. The Board of Directors shall exercise all of
the powers of the Corporation except such as are


                                        7

upon or reserved to the stockholders.

               SECTION 3.7. COMMITTEES. The Board of Directors may, by
resolution or resolutions passed by a majority of the Board of Directors,
designate one or more committees, each committee to consist of two or more of
the directors of the Corporation. The Board of Directors 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 any member of such committee or committees, the member or
members thereof present at any such 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, or in these By-laws, 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; but no such committee shall have

Certificate of Incorporation expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock.

the Corporation's principal office or such places as the committee shall from
time to time determine. Special meetings of such committee may be called at any
time by the President or a majority of the members of the committee, to convene
at such time and place as may be appointed.

        A majority of the members of a committee shall constitute a quorum. If a
quorum is not present at any meeting, the members present may adjourn the
meeting until a later date or hour; or the members present, whether constituting
a quorum or not, at his or their option, shall have the power to appoint a
substitute or substitutes from the members of the Board of Directors to act
during the temporary absence of any member or members of the committee.

        The members of a committee shall appoint one of their members to act as
secretary and keep the minutes thereof. A copy of the minutes for each committee
meeting held subsequent to the


                                        8

stockholders for the election of directors is held, and as soon as practicable
thereafter, the Board of Directors may hold its annual meeting, without notice
of such meeting, for the purposes of organization, the election of officers and
the transaction of other business. The annual meeting of the Board of Directors
may be held at any other time and place specified in a notice given as provided
in this section for special meetings of the Board of Directors or in a waiver of
notice thereof.

               Regular meetings of the directors may be held without notice at
such place and times as shall be determined from time to time by resolution of
the directors.

               Special meetings of the Board may be called by the President or
by the Secretary on the written request of any two or more directors on at least
two days' notice to each director and shall be held at such place or places as
may be determined by the directors, or as shall be stated in the notice of the
meeting.

               Anything in the By-laws or in any resolution adopted by the Board
of Directors to the contrary notwithstanding, notice of any meeting of the Board
of Directors need not be given to any director who submits a signed waiver of
such notice, whether before or after such meeting, or who attends such meeting
without protesting, prior thereto or at its commencement, the lack of notice to
him.

               SECTION 3.9. TELEPHONE MEETING. Members of the Board of Directors
or any committee designated by such Board of Directors may participate in a
meeting of the Board of Directors or such committee by means of telephone
conference or similar communication equipment by means of which all persons

this section shall constitute presence at such meeting.

               SECTION 3.10. QUORUM. A majority of the directors in office from
time to time shall constitute a quorum for the transaction of business. If at
any meeting of the Board of Directors there shall be less than a quorum present,

quorum is obtained, and no further notice thereof need be given other than by
announcement at the meeting which shall be so adjourned.

               SECTION 3.11. COMPENSATION. Directors shall not receive any
stated salary for their services as directors or as members of committees, but
by resolution of the Board of Directors a fixed fee and expenses of attendance
may be allowed for attendance at each meeting. Nothing herein contained shall be
construed to preclude any director from serving the Corporation or its
subsidiaries in any other capacity as an officer, agent or otherwise, and
receiving compensation therefor.

               SECTION 3.12. ACTION WITHOUT MEETING. Any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting, if a written consent thereto

officers as between themselves and the Corporation shall have such authority and
perform such duties in the management of the Corporation as may be provided in
the By-laws or as the Board of Directors may from time to time determine.

               SECTION 4.2. REMOVAL OF OFFICERS. Any officer elected or
appointed by the Board of Directors may be removed by the Board of Directors
with or without cause. The removal of an officer without cause shall be without
prejudice to his contract rights, if any. The election or appointment of an
officer shall not of itself create contract rights.

               SECTION 4.3.  RESIGNATIONS.  Any officer may resign at
any time by notifying the Board of Directors or the President in

the fact that he is also a director.

executive officer of the Corporation and shall have general supervision over the

Corporation itself or its employee. In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon any
certificate shall have ceased to be such officer, transfer agent or registrar
before such certificate is issued, such certificate may, unless otherwise
ordered by the Board of Directors, be issued by the Corporation with the same

               SECTION 6.2. TRANSFER OF SHARES. Transfers of shares of capital
stock of the Corporation shall be made only on the books of the Corporation by
the holder thereof or by his duly authorized attorney appointed by a power of

such shares of capital stock properly endorsed for transfer and upon payment of
all necessary transfer taxes. Every certificate exchanged, returned or
surrendered to the Corporation shall be marked "Cancelled" with the date of
cancellation, by the Secretary or an Assistant Secretary or the transfer agent
of the Corporation. A person in whose name shares of capital stock shall stand
on the books of the Corporation shall be deemed the owner thereof to receive
dividends, to vote as such owner and for all other purposes as respects the
Corporation, its stockholders and creditors for any purpose, except to render
the transferee liable for the debts of the Corporation to the extent provided by
law, until such transfer shall have been entered on the books of the Corporation
by an entry showing from and to whom transferred.

               SECTION 6.3. TRANSFER AND REGISTRY AGENTS. The Corporation may
from time to time maintain one or more transfer offices or agents and registry
offices or agents at such place or places as may be determined from time to time
by the Board of Directors.

               SECTION 6.4. LOST, DESTROYED, STOLEN AND MUTILATED CERTIFICATES.

and the Corporation may


                                       14


<PAGE>
<PAGE>



issue a new certificate to replace the certificate alleged to have been lost,
destroyed, stolen or mutilated. The Board of Directors may, in its discretion,
as a condition to the issue of any such new certificate, require the owner of
the lost, destroyed, stolen or mutilated certificate, or his legal
representatives, to make proof satisfactory to the Board of Directors of such
loss, destruction, theft or mutilation and to advertise such fact in such manner
as the Board of Directors may require, and to give the Corporation and its
transfer agents and registrars, or such of them as the Board of Directors may
require, a bond in such form, in such sums and with such surety or sureties as
the Board of Directors may direct, to indemnify the Corporation and its transfer
agents and registrars against any claim that may be made against any of them on
account of the continued existence of any such certificate so alleged to have
been lost, destroyed, stolen or mutilated and against any expense in connection
with such claim.

               SECTION 6.5. REGULATIONS. The Board of Directors may make rules
and regulations as it may deem expedient, not inconsistent with the By-laws or
with the Certificate of Incorporation, concerning the issue, transfer and
registration of certificates representing shares of its capital stock.

               SECTION 6.6. RESTRICTION ON TRANSFER OF STOCK. A written
restriction on the transfer or registration of transfer of capital stock of the
Corporation, if permitted by Section 202 of the GCL and noted conspicuously on
the certificate representing such capital stock, may be enforced against the
holder of the restricted capital stock of any successor or transferee of the
holding including an executor, administrator, trustee, guardian or other
fiduciary entrusted with like responsibility for the person or estate of the
holder. Unless noted conspicuously on the certificate representing such capital
stock, a restriction even though permitted by Section 202 of the GCL, shall be
ineffective except against a person with actual knowledge of the restriction. A
restriction on the transfer or registration of transfer of capital stock of the
Corporation may be imposed either by the Certificate of Incorporation or by an
agreement among any number of stockholders or among such stockholders and the
Corporation. No restriction so imposed shall be binding with respect to capital
stock issued prior to the adoption of the restriction unless the holders of such
capital stock are parties to an agreement or voted in favor of the restriction.
In connection with any offer by the Corporation of any company securities to a
non-United States person, the Corporation shall not, and shall instruct its
transfer agent not to effect any transfer of those shares in the United States
or to or for the account or benefit of a United States person unless the
purchaser delivers to the corporation an opinion of counsel satisfactory to the
Corporation that such transfer is permitted under the United States Securities
Act of 1933.

        affairs of the Corporation shall render advisable;

                      6.7.2 may use and apply, in its discretion, any of the
        surplus of the Corporation in purchasing or acquiring any shares of
        capital stock of the Corporation, or purchase warrants therefor, in
        accordance with law, or any of its bonds, debentures, notes, scrip or
        other securities or evidences or indebtedness;

                      6.7.3 may set aside from time to time out of such surplus
        or net profits such sum or sums as, in its discretion, it may think
        proper, as a reserve fund to meet contingencies, or for equalizing
        dividends or for the purpose of maintaining or increasing the property
        or business of the Corporation, or for any other purpose it may think
        conducive to the best interests of the Corporation.

                                  ARTICLE VIII
                          INDEMNIFICATION AND INSURANCE

               SECTION 8.1 INDEMNIFICATION. The Corporation shall, to the
fullest extent permitted by Delaware law, as the same may be amended and
supplemented, indemnify any and all persons to 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 By-law, agreement,
vote of stockholders or disinterested directors or otherwise, both as to an
action in his official capacity and 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. The right to indemnification
conferred in this paragraph shall be a contract right and shall include the
right to be paid by the Corporation the expenses incurred in defending any such
proceeding in advance of its final disposition; provided, however, that, if the
GCL requires the payment of such expenses incurred by a director or officer in
his or her capacity as a director or officer (and not in any other capacity in
which service was or is rendered by such person while a director or officer,
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a proceeding, such payment shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director
or officer, to repay all amounts so advanced if it shall ultimately be
determined that such director or officer is not entitled to be indemnified under
this paragraph or otherwise.

               SECTION 8.2 INSURANCE. The Corporation may purchase and maintain
insurance on behalf of any person who is or was a director, officer or employee
of the Corporation, or is or was serving at the request of the Corporation as a
director, officer or employee of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power to indemnify him against
such liability under the provisions of this Article VIII or of the GCL.

               SECTION 8.3 INDEMNIFICATION AGREEMENTS. Without limiting the
generality of the foregoing and subject to the provisions of the Certificate of
Incorporation, the Corporation shall have the express authority to enter into
such agreements as the Board of Directors deems appropriate for the
indemnification of present or future directors and officers of the Corporation
in connection with their service to or status with the Corporation or any other
corporation, entity or enterprise with whom such person is serving at the
express written request of the Corporation.

                Common Stock, par value $.01 per share.

Ladies and Gentlemen:

               In connection with the registration of 4,025,000 shares of common
stock of the Company, par value $.01 per share (the "Shares"), under the
Securities Act of 1933, as amended (the "Act"), by Algos Pharmaceutical
Corporation, a Delaware corporation (the "Company"), on Form S- 1 filed with the
Securities and Exchange Commission (the "Commission") on May 22, 1996 (File No.
333-04313), as amended by Amendment No. 1 filed with the Commission on August
30, 1996 (collectively, the "Registration Statement"), you have requested our
opinion with respect to the matters set forth below.

               In our capacity as your counsel in connection with such
registration, we are familiar with the proceedings taken and proposed to be
taken by the Company in connection with the authorization, issuance and sale of
the Shares, and for the purposes of this opinion, have assumed such
proceedings will be timely completed in the manner presently proposed. In
addition, we have made such legal and factual examinations and inquiries,
including an examination of originals or copies certified or otherwise
identified to our satisfaction of such documents, corporate records and
instruments, as we have deemed necessary or appropriate for purposes of this
opinion.

               In our examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, and
the conformity to authentic original documents of all documents submitted to us
as copies.

               We are opining herein as to the effect on the subject transaction
only of the internal laws of the State of New York and the General Corporation
Law of the State of Delaware, and we express no opinion with respect to the
applicability thereto, or the effect thereon, of the laws of any other
jurisdiction or, in the case of Delaware, any other laws, or as to any matters
of municipal law or the laws of any other local agencies within the state.

               Subject to the foregoing, it is our opinion that the Shares have
been duly authorized, and, upon issuance, delivery and payment therefor in the
manner contemplated by the Registration Statement, will be validly issued, fully
paid and nonassessable.

               We consent to your filing this opinion as an exhibit to the
Registration Statement and to the reference to our firm contained under the

        (b) Except as provided in this Section 5, the aggregate number of Shares
that may be issued under the Plan shall not exceed one hundred thousand
(100,000) Shares, such number determined after giving effect to the stock split

Options shall be again be available for the grant of Options, subject to the
limit provided by the preceding sentence.

        (c) No fractional Shares will be issued or transferred in the exercise
of any Option. In lieu thereof, the Company shall pay a cash adjustment equal to
the same fraction of the Fair Market Value of one Share on the date of exercise.

        (d) The existence of the Plan and the Options granted hereunder shall
not affect in any way the right or power of the Board or the stockholders of the
Company to make or authorize any adjustment, recapitalization, reorganization or
other change in the Company's capital structure or its business, any merger or
consolidation of the Company, any issue of bonds, debentures, preferred or prior
preference stocks ahead of or affecting Common Stock, the dissolution or
liquidation of the Company or any sale or transfer of all or part of its assets
or business, or any other corporate act or proceeding, in which case the
provisions of this Section 5 shall govern outstanding Options.

        (e) The Shares with respect to which Options may be granted are Shares
of Common Stock as presently constituted, but, if and whenever, prior to the
expiration of an Option theretofore


                                             3

granted, the Company shall effect a subdivision, recapitalization or
consolidation of Shares or the payment of a stock dividend on Shares without
receipt of consideration, the purchase price per Share and the number and class
of Shares and/or other securities with respect to which such Option thereafter
may be exercised, and the total number and class of Shares and/or other
securities that may be issued under this Plan, shall be proportionately
adjusted.

        (f) If the Company merges or consolidates with one or more corporations,
then from and after the effective date of such merger or consolidation, upon
exercise of an Option theretofore granted, the Participant shall be entitled to
purchase under such Option, in lieu of the number of Shares as to which such
Option shall then be exercisable but on the same terms and conditions of
exercise set forth in such Option, the number and class of Shares and/or other
securities or property (including cash) to which the Participant would have been
entitled pursuant to the terms of the agreement of merger or consolidation if,
immediately prior to such merger or consolidation, the Participant had been the
holder of record of the total number of Shares receivable upon exercise of such
Option (whether or not then exercisable) had such merger or consolidation not
occurred.

        (g) If, as a result of any adjustment made pursuant to the preceding
paragraphs of this Section 5, any Participant shall become entitled upon
exercise of an Option to receive any securities other than Common Stock, then
the number and class of securities so receivable thereafter shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Common Stock set forth in this
Section 5.

Company of shares of stock of any class, or securities convertible into shares
of stock of any class, for cash, property, labor or services, upon direct sale,

conversion of shares or other securities, and in any case whether or not for
fair value, shall not affect, and no adjustment by reason thereof shall be made
with respect to, the number and class of Shares and/or other securities or
property subject to Options theretofore granted or the purchase price per Share.

        (i) Notwithstanding any provision of this Section 5 to the contrary, if
authorized but previously unissued Shares are issued under the Plan, such Shares
shall not be issued for a consideration less than their par value.

evidenced by Option agreements in such forms not inconsistent with the Plan as
the Board shall approve from time to time, which agreements shall contain in
substance the following terms and conditions:

               (i) Exercise Price. The purchase price per Share deliverable upon
        the exercise of an Option shall be determined by the Board, but not less
        than one hundred percent (100%) of the Fair Market Value of a Share at
        the time of the grant of the Option, or the par value of a Share,
        whichever is the greater.

               (ii) Number of Shares. The Option agreement shall specify the
        number of Options granted to the Participant, as determined by the Board
        in its sole discretion. If some of the Options held by a Participant are
        exercised, any unexercised Options held by him shall remain outstanding
        and shall be or become exercisable according to their respective terms.

               (iii) Period of Exercisability. The Board shall, in its sole
        discretion, prescribe periods of exercisability and additional
        requirements or conditions with respect to the exercise of Options in
        the Option agreement and may provide, either at the time of grant or
        thereafter, for the acceleration of an Option; provided, however, that
        no Option shall be exercisable after the expiration of ten (10) years
        from the date of grant. Except as hereinafter provided, Options granted
        to any Participant may be exercised only during the continuance of that
        Participant's employment by the Company.

               (iv) Procedure for Exercise. A Participant electing to exercise
        one or more Options shall give written notice to the Board of such
        election and of the number of Options he has elected to exercise. Shares
        purchased pursuant to the exercise of Options shall be paid for in cash
        at the time of exercise unless the Board, in its sole discretion, shall
        permit payment in whole or in part through the delivery of other Shares
        owned by the Participant, by reduction in the number of shares issuable
        upon such exercise, or on such other terms and conditions as may be
        acceptable to the Board and in accordance with Delaware law. Upon
        receipt of payment, the Company shall deliver to the Participant as soon
        as practicable a certificate or certificates for the Shares then
        purchased.

        (b) Expiration and Cancellation. If not previously exercised, each
Option shall expire no later than the tenth (10th) anniversary of the date of
the grant thereof or, except as otherwise provided by Section 7 of the Plan, the
earlier termination of the Participant's employment by Company.

7.      EFFECT OF TERMINATION OF EMPLOYMENT

        (a) By Reason of Participant's Death. If the Participant dies while an
employee of the Company, all outstanding Options that are exercisable as of the
date of death shall, unless otherwise specified in his Option agreement, remain
exercisable by the Participant's estate or by the person given authority to
exercise such Options by his will or by operation of law for a period of one (1)
year from the date of the Participant's death; provided, however, that (i) no
Options that were not exercisable on the date of the Participant's death shall
thereafter become exercisable, and (ii) no Option may be exercised more than ten
(10) years from the date of grant.

        (b) By Reason of the Participant's Disability. If a Participant's
employment with the Company terminates due to disability (within the meaning of
Section 22(e)(3) of the Code), all outstanding Options that are exercisable as
of the effective date of such termination of employment shall, unless otherwise
specified in his Option agreement, remain exercisable for a period of one (1)
year from the date of termination of the Participant's employment; provided,
however, that (i) no Options that were not exercisable on the effective date of
the Participant's termination of employment shall thereafter become exercisable,
and (ii) no Option may be exercised more than ten (10) years after the date of
the grant.

        (c) By Reason of Other Separation from Service. If a Participant's
service is terminated for cause (as hereinafter defined) or is terminated by the
Participant in violation of an agreement between the Participant and the
Company, or if it is discovered after his separation from service that he had
engaged in conduct that would have justified termination of his employment for
cause, all unexercised and outstanding Options held by the Participant shall,
unless otherwise specified in his Option agreement, immediately be cancelled.
Unless otherwise defined in his Option agreement, termination shall be deemed to
be for "cause" if the Participant shall have (i) taken willful or negligent
action which materially harms, or can reasonably be expected to harm, the
Company, (ii) committed fraud, misappropriation, embezzlement, or criminal
misconduct that would constitute a felony or any other act or conduct, whether
criminal or noncriminal, and regardless of whether committed in the course of
the Company's business, which adversely affects the reputation of the Company or
otherwise brings disrepute on the Company or its affiliates, or (iii) committed
a breach of, or default under, any provision, term or covenant of any agreement
between the Participant and the Company. Upon any termination of employment not
governed by the preceding portion of this Section 7(c) or by Sections 7(a) or
7(b) hereof, all outstanding Options that are exercisable as of the effective
date of such termination of employment shall, unless otherwise specified in the
Option agreement, remain exercisable for a period of three (3) months after such
termination; provided, however, that (i) no Options


                                             6


<PAGE>
<PAGE>



that were not exercisable on the effective date of the Participant's termination
of employment shall thereafter become exercisable and (ii) no Option may be
exercised more than ten (10) years after the date of the grant.

        (d) Employment by Affiliate. For purposes of the Plan, employment by the
Company shall be considered to include employment by a parent corporation or
subsidiary corporation of the Company as such terms are defined in Sections
424(e) and (f), respectively, of the Code.

8.      NONTRANSFERABILITY OF OPTIONS

        No Option shall be transferable by the Participant otherwise than by
will or under applicable laws of descent and distribution. In addition, no
Option shall be assigned, negotiated, pledged, hypothecated in any way (whether
by operation of law or otherwise), and no Option shall be subject to execution,
attachment or similar process. Upon any attempt to transfer, assign, negotiate,
pledge or hypothecate any Option contrary to the provisions hereof, or in the
event of any levy upon any Option by reason of any attachment or similar
process, such Option shall immediately become null and void.

9.      RIGHTS AS A STOCKHOLDER

        A Participant (or a permitted transferee of an Option) shall have no
rights as a stockholder with respect to any shares covered by his Option until
he shall have become the holder of record of such Share(s), and no adjustments
shall be made for dividends in cash or other property or distributions or other
rights in respect to any such Shares, except as otherwise specifically provided
for in this Plan.

10.     DETERMINATION

        Each determination, interpretation or other action made or taken
pursuant to the provisions of this Plan by the Board shall be final and binding
for all purposes and upon all persons, including, without limitation, the
Company, the directors, officers and other employees of the Company, the
Participants and their respective heirs, executors, administrators, personal
representatives and other successors in interest.

11.     TERMINATION, AMENDMENT AND MODIFICATION

        (a) The Plan shall terminate at the close of business on January 25,
2004, unless sooner terminated as hereinafter provided, and no Option shall be
granted under the Plan thereafter. At any time prior to that date, the Board may
terminate the Plan or suspend the Plan in whole or in part or amend the Plan
(including, without limitation, amendments deemed necessary or desirable in the
sole discretion of the Board in order that the Options shall conform to any
change in the law or


                                             7


<PAGE>
<PAGE>



regulations applicable thereto or in order to qualify the Plan for favorable
treatment under foreign tax laws). Notwithstanding the foregoing, however, no
such action may, without the approval of the stockholders of the Company,
increase the total number of Shares which may be acquired upon exercise of
Options granted under the Plan; reduce the minimum exercise price at which any
Option may be exercised below the greater of one hundred percent (100%) of the
Fair Market Value of one Share on the date of grant or the par value of one
Share; or change the class of employees eligible to be Participants.

        (b) Nothing contained in this Section 11 shall be deemed to prevent the
Board from authorizing amendments of outstanding Options; including, without
limitation, the reduction of the exercise price specified therein (or the
granting or issuance of new Options at a lower exercise price upon cancellation
of outstanding Options), so long as all Options outstanding at any one time
shall not call for issuance of more Shares than the remaining number provided
for under the Plan and so long as the provisions of any amended Options would
have been permissible under the Plan if such Option had been originally granted
or issued as of the date of such amendment with such amended terms.
Notwithstanding anything to the contrary contained in this Section 11, no
termination, amendment or modification of the Plan may, without the consent of
the Participant or the transferee of his Option, alter or impair the rights and
obligations arising under any then outstanding Option.

12.     NON-EXCLUSIVITY

        Neither the adoption of the Plan by the Board nor the submission of the
Plan to the stockholders of the Company for approval shall be construed as
creating any limitations on the power of the Board to adopt such other incentive
arrangements as it may deem desirable, including, without limitation, the
granting or issuance of stock options, Shares and/or other incentives otherwise
than under the Plan, and such arrangements may be either generally applicable or
limited in application.

13.     USE OF PROCEEDS

        The proceeds of the sale of Shares subject to Options under the Plan are
to be added to the general funds of the Company and used for its general
corporate purposes as the Board shall determine.

14.     GENERAL PROVISIONS

        (a) The Plan shall not impose any obligations on the Company to continue
the employment of any Participant, nor shall it impose any obligation on the
part of any Participant to remain in the employ of the Company.



                                             8



<PAGE>
<PAGE>



        (b) If the Board determines that the law so requires, the holder of an
Option granted hereunder shall, upon any exercise or conversion thereof, execute
and deliver to the Company a written statement, in form satisfactory to the
Company, representing and warranting that he is purchasing or accepting the
Shares then acquired for his own account and not with a view to the resale or
distribution thereof, that any subsequent offer for sale or sale of any such
Shares shall be made either pursuant to (i) a Registration Statement on an
appropriate form under the Securities Act of 1933, as amended, which
Registration Statement shall have become effective and shall be current with
respect to the Shares being offered and sold, or (ii) a specific exemption from
the registration requirements of said Act, and that in claiming such exemption
the holder will, prior to any offer for sale or sale of such Shares, obtain a
favorable written opinion from counsel approved by the Company as to the
availability of such exemption.

        (c) Nothing contained in the Plan and no action taken pursuant to the
Plan (including without limitation the grant of any Option thereunder) shall
create or be construed to create a trust of any kind, or a fiduciary
relationship, between the Company and any Participant or the executor,
administrator or other personal representative, or designated beneficiary of
such Participant, or any other persons. Any reserves that may be established by
the Company in connection with the Plan shall continue to be part of the general
funds of the Company, and no individual or entity other than the Company shall
have any interest in such funds until paid to a Participant. If and to the
extent that any Participant or his executor, administrator or other personal
representative, as the case may be, acquires a right to receive any payment form
the Company pursuant to the Plan, such right shall be no greater than the right
of an unsecured general creditor of the Company.

15.     ISSUANCE OF STOCK CERTIFICATES, LEGENDS AND PAYMENT OF
        EXPENSES

        (a) Upon any exercise of an Option and payment of the exercise price as
provided in such Option, a certificate or certificates for the Shares as to
which such Option has been exercised shall be issued by the Company in the name
of the person or persons exercising such Option and shall be delivered to or
upon the order of such person or persons.

        (b) Certificates for Shares issued upon exercise of an Option shall bear
such legend or legends as the Board, in its discretion, determines to be
necessary or appropriate to prevent a violation of, or to perfect an exemption
from, the registration requirements of the Securities Act of 1933, as amended,
or to implement the provisions of any agreements between the Company and the
Participant with respect to such Shares.



                                             9



<PAGE>
<PAGE>



        (c) The Company shall pay all issue or transfer taxes with respect to
the issuance or transfer of Shares, as well as all fees and expenses necessarily
incurred by the Company in connection with such issuance or transfer and with
the administration of the Plan.

16.     LISTING OF SHARES AND RELATED MATTERS

        If at any time the Board shall determine in its discretion that the
listing, registration or qualification of the Shares covered by the Plan upon
any national securities exchange or under any state or federal law, or the
consent or approval of any governmental regulatory body, is necessary or
desirable as a condition of, or in connection with, the award or sale of Shares
under the Plan, no Shares will be delivered unless and until such listing,
registration, qualification, consent or approval shall have been effected or
obtained, or otherwise provided for, free of any conditions not acceptable to
the Board.

17.     WITHHOLDING TAXES

        The Company shall have the right to deduct withholding taxes from any
payments made pursuant to the Plan, or to make such other provisions as it deems
necessary or appropriate to satisfy its obligations to withhold federal, state
or local income or other taxes incurred by reason of the exercise of Options or
the issuance of Shares or payments under the Plan, including requiring a
Participant exercising an Option granted hereunder to reimburse the Company for
any taxes required to be withheld or otherwise deducted and paid by the Company
in respect of the Option exercise or the issuance of Shares pursuant thereto. In
lieu thereof, the Company shall have the right to withhold the amount of such
taxes from any other sums due or to become due from the Company to the
Participant upon such terms and conditions as the Board may prescribe.

18.     NOTICES

        Each Participant shall be responsible for furnishing the Board with the
current and proper address for the mailing to him of notices and the delivery to
him of agreements, Shares and payments. Any notices required or permitted to be
given shall be deemed given if directed to the person to whom addressed at such
address and mailed by regular United States mail, first-class and prepaid. If
any item mailed to such address is returned as undeliverable to the addressee,
mailing will be suspended until the Participant furnishes the proper address.

19.     SEVERABILITY OF PROVISIONS

        If any provisions of the Plan shall be held invalid or unenforceable,
such invalidity or unenforceability shall not affect any other provisions of the
Plan, and the Plan shall be


                                             10



<PAGE>
<PAGE>


construed and enforced as if such provisions had not been
included.

20.     PAYMENT TO MINORS, ETC.

        Any benefit payable to or for the benefit of a minor, an incompetent
person or other person incapable of receipting therefor shall be deemed paid
when paid to such person's guardian or to the party providing or reasonably
appearing to provide for the care of such person, and such payment shall fully
discharge the Board, the Company and their employees, agents and representatives
with respect thereto.

21.     HEADINGS AND CAPTIONS

        The headings and captions herein are provided for reference and
convenience only. They shall not be considered part of the Plan and shall not be
employed in the construction of the Plan.

22.     CONTROLLING LAW

        The Plan shall be construed and enforced according to the laws of the
State of New York.

and unrestricted right to terminate an Employee's employment at any time for any
reason  whatsoever,  with or  without  Cause,  except  to the  extent  expressly
provided otherwise in writing.

                                   ARTICLE II

                             SHARES SUBJECT TO PLAN

               2.1 Shares Subject to Plan.

               (a) The shares of stock subject to Options shall be Common Stock.
The  aggregate  number of such shares which may be issued upon  exercise of such
Options under the Plan shall not exceed fifty thousand  (50,000).  The shares of
Common Stock  issuable  upon  exercise of such options may be either  previously
authorized but unissued shares or treasury shares.

               (b) The maximum  number of shares which may be subject to Options
granted  under the Plan to any  individual in any calendar year shall not exceed
the Award Limit.  To the extent  required by Section 162(m) of the Code,  shares
subject to Options which are cancelled  continue to be counted against the Award
Limit and if,  after  grant of an  Option,  the price of shares  subject to such
Option is reduced,  the  transaction is treated as a cancellation  of the Option
and a grant of a new Option and both the Option  deemed to be cancelled  and the
Option deemed to be granted are counted against the Award Limit.

               2.2 Add-back of Options. If any Option under this Plan expires or
is cancelled without having been fully exercised, or is exercised in whole or in
part for cash as  permitted by this Plan,  the number of shares  subject to such
Option but as to which such Option was not  exercised  prior to its  expiration,
cancellation  or  exercise  may  again be  optioned  hereunder,  subject  to the
limitations of Section 2.1. Furthermore, any shares subject to Options which are
adjusted  pursuant to Section 7.3 and become  exercisable with respect to shares
of stock of another  corporation shall be considered  cancelled and may again be
optioned hereunder,  subject to the limitations of Section 2.1. Shares of Common
Stock which are  delivered  by the  Optionee or withheld by the Company upon the
exercise of any Option under this Plan, in payment of the exercise price thereof
or withholding taxes thereon,  may again be optioned  hereunder,  subject to the
limitations of Section 2.1.  Notwithstanding the provisions of this Section 2.2,
no shares of Common  Stock may again be optioned  if such action  would cause an
Incentive  Stock  Option to fail to qualify as an  incentive  stock option under
Section 422 of the Code.

                               GRANTING OF OPTIONS

               3.1  Eligibility.  Any  Employee  or  consultant  selected by the
Committee  pursuant  to Section  3.3(a)(i)  shall be  eligible  to be granted an
Option.

               3.2 Qualification of Incentive Stock Options.  No Incentive Stock
Option  shall be granted  unless such  Option,  when  granted,  qualifies  as an
"incentive  stock  option"  under  Section 422 of the Code.  No Incentive  Stock
Option shall be granted to any person who is not an Employee.

               3.3    Granting of Options

               (a) The Committee shall from time to time, in its discretion, and
subject to applicable limitations of this Plan:

                       (i)  Determine  which  Employees  are key  Employees  and
        select from among the key Employees and consultants (including Employees
        and consultants who have  previously  received  Options under this Plan)
        such of them as in its opinion should be granted Options;

                      (ii) Subject to the Award Limit,  determine  the number of
        shares  to be  subject  to such  Options  granted  to the  selected  key
        Employees or consultants;

                     (iii)  Determine  whether  such Options are to be Incentive
        Stock  Options or  Non-Qualified  Stock Options and whether such Options
        are to qualify as performance-based compensation as described in Section
        162(m)(4)(C) of the Code; and

                      (iv)  Determine the terms and  conditions of such Options,
        consistent  with  this  Plan;  provided,  however,  that the  terms  and
        conditions   of  Options   intended  to  qualify  as   performance-based
        compensation  as  described  in Section  162(m)(4)(C)  of the Code shall
        include,  but not be limited  to,  such terms and  conditions  as may be
        necessary to meet the  applicable  provisions  of Section  162(m) of the
        Code.

               (b) Upon the  selection  of a key  Employee or  consultant  to be
granted an Option,  the Committee shall instruct the Secretary of the Company to
issue the Option and may impose such conditions on the grant of the Option as it
deems  appropriate.  Without limiting the generality of the preceding  sentence,
the Committee may, in its discretion and on such terms as it deems  appropriate,
require as a condition  on the grant of an Option to an  Employee or  consultant
that the Employee or consultant  surrender for  cancellation  some or all of the
unexercised  options which have been previously granted to him or her under this
Plan or  otherwise.  An  Option,  the  grant of which is  conditioned  upon such
surrender, may have an option price lower (or higher) than the exercise price of
such  surrendered  option may cover the same (or a lesser or greater)  number of
shares as such surrendered  Option may contain such other terms as the Committee
deems  appropriate,  and shall be  exercisable  in  accordance  with its  terms,
without regard to the number of shares, price, exercise period or any other term
or condition of such surrendered option.

               (c) Any  Incentive  Stock Option  granted  under this Plan may be
modified  by the  Committee  to  disqualify  such option  from  treatment  as an
"incentive stock option" under Section 422 of the Code.



                                   ARTICLE IV

                                TERMS OF OPTIONS

               4.1 Option Agreement. Each Option shall be evidenced by a written
Option  Agreement,  which shall be executed by the  Optionee  and an  authorized
officer of the Company and which shall contain such terms and  conditions as the
Committee  shall  determine,   consistent  with  this  Plan.  Option  Agreements
evidencing  Options  intended to qualify as  performance-based  compensation  as
described  in  Section  162(m)(4)(C)  of the Code shall  contain  such terms and
conditions  as may be necessary  to meet the  applicable  provisions  of Section
162(m) of the Code. Option Agreements  evidencing  Incentive Stock Options shall
contain such terms and  conditions  as may be  necessary to meet the  applicable
provisions of Section 422 of the Code.

               4.2 Exercise Price.  The price per share of the shares subject to
each Option shall be set by the Committee and specified in the Option Agreement;
provided,  however,  that  such  price  shall be no less than the par value of a
share of Common Stock,  unless otherwise  permitted by applicable state law, and
(a) in the case of Incentive  Stock  Options and Options  intended to qualify as
performance-based compensation as described in Section 162(m)(4)(C) of the Code,
such price  shall not be less than 100% of the Fair  Market  Value of a share of
Common  Stock on the date the Option is granted and (b) in the case of Incentive
Stock  Options  granted to an  individual  then  owning  (within  the meaning of
Section 424(d) of the Code) more than 10% of the total combined  voting power of
all  classes of stock of the  Company or any  Subsidiary  or parent  corporation
thereof  (within the meaning of Section 422 of the Code) such price shall not be
less than 110% of the Fair Market  Value of a share of Common  Stock on the date
the Option is granted.

               4.3  Option  Term.  The  term of an  Option  shall  be set by the
Committee in its discretion;  provided,  however, that, in the case of Incentive
Stock Options,  the term shall not be more than ten (10) years from the date the
Incentive  Stock  Option is  granted,  or five (5)  years  from such date if the
Incentive  Stock  Option is granted to an  individual  then  owning  (within the
meaning  of  Section  424(d)  of the Code)  more than 10% of the total  combined
voting power of all classes of stock of the Company or any  Subsidiary or parent
corporation  thereof (within the meaning of Section 422 of the Code).  Except as
limited by  requirements  of Section 422 of the Code and regulations and rulings
thereunder  applicable to Incentive Stock Options,  the Committee may extend the
term of any outstanding  Option in connection with any Termination of Employment
or  Termination  of  Consultancy  of the  Optionee,  or amend any other  term or
condition of such Option relating to such a termination.

               4.4      Option Vesting

               (a) The period  during  which the right to  exercise an Option in
whole or in part vests in the  Optionee  shall be set by the  Committee  and the
Committee may determine  that an Option may not be exercised in whole or in part
for a  specified  period  after it is  granted.  At any time  after  grant of an
Option,  the Committee may, in its sole discretion and subject to whatever terms
and conditions it selects, accelerate the period during which an Option vests.

<PAGE>




               (b)  No  portion  of an  Option  which  is  unexercisable  at the
Optionee's  Termination  of  Employment  or  Termination  of  Consultancy  shall
thereafter  become  exercisable,  except  as may be  otherwise  provided  by the
Committee either in the Option Agreement or by action of the Committee following
the grant of the Option.

               (c) To the extent that the  aggregate  Fair Market Value of stock
with respect to which  "incentive  stock options" (within the meaning of Section
422 of the  Code,  but  without  regard  to  Section  422(d)  of the  Code)  are
exercisable  for the first time by an Optionee  during any calendar  year (under
the Plan and all other  incentive  stock  option  plans of the  Company  and any
Subsidiary)  exceeds  $100,000,  such Options shall be treated as  Non-Qualified
Options to the extent required by Section 422 of the Code. The rule set forth in
the preceding  sentence  shall be applied by taking  Options into account in the
order in which they were granted.  For purposes of this Section 4.4(c), the Fair
Market Value of stock shall be determined as of the time the Option with respect
to such stock is granted.

               4.5 Consideration. In consideration of the granting of an Option,
the Optionee shall agree,  in the written Option  Agreement,  to render faithful
and  efficient  services  to the Company or a  Subsidiary,  with such duties and
responsibilities as the Company or Subsidiary shall from time to time prescribe.
Nothing in the Plan or any Option  Agreement  shall confer upon any Optionee any
right to continue in the employ of, or as a  consultant  for, the Company or any
Subsidiary  or shall  interfere  with or  restrict  in any way the rights of the
Company and any Subsidiary,  which are hereby expressly  reserved,  to discharge
any Optionee at any time for any reason whatsoever, with or without Cause.


                                    ARTICLE V

                               EXERCISE OF OPTIONS

               5.1 Partial Exercise.  An exercisable  Option may be exercised in
whole or in part.  However,  an Option shall not be exercisable  with respect to
fractional shares and the Committee may require that, by the terms of the Option
Agreement, a partial exercise be with respect to a minimum number of shares.

               5.2 Manner of Exercise. All or a portion of an exercisable Option
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his or her office:

               (a)  A  written  notice   complying  with  the  applicable  rules
established by the Committee stating that the Option,  or a portion thereof,  is
exercised.  The notice  shall be signed by the  Optionee  or other  person  then
entitled to exercise the Option or such portion;

               (b) Such  representations and documents as the Committee,  in its
discretion,   deems  necessary  or  advisable  to  effect  compliance  with  all
applicable  provisions of the Securities Act, as amended,  and any other federal
or state  securities laws or regulations.  The Committee may, in its discretion,
also take  whatever  additional  actions  it deems  appropriate  to effect  such
compliance including, without limitation,  placing legends on share certificates
and issuing stop-transfer notices to agents and registrars;

               (c) In the event that the Option shall be  exercised  pursuant to
Section 7.1 by any person or persons other than the Optionee,  appropriate proof
of the right of such person or persons to exercise the Option; and


                                             7



<PAGE>
<PAGE>




               (d) Full cash  payment to the  Secretary  of the  Company for the
shares  with  respect to which the Option,  or portion  thereof,  is  exercised.
However, the Committee may, in its discretion (i) allow a delay in payment up to
thirty (30) days from the date the Option,  or portion  thereof,  is  exercised;
(ii) allow  payment,  in whole or in part,  through  the  delivery  of shares of
Common Stock owned by the  Optionee,  duly  endorsed for transfer to the Company
with a Fair Market Value on the date of delivery equal to the aggregate exercise
price of the Option or exercised portion thereof;  (iii) allow payment, in whole
or in part,  through the  surrender of shares of Common Stock then issuable upon
exercise of the Option having a Fair Market Value on the date of Option exercise
equal  to the  aggregate  exercise  price of the  Option  or  exercised  portion
thereof;  (iv) allow  payment,  in whole or in part,  through  the  delivery  of
property of any kind which  constitutes  good and  valuable  consideration;  (v)
allow  payment,  in whole or in part,  through the  delivery of a full  recourse
promissory  note  bearing  interest  (at no less than  such  rate as shall  then
preclude the  imputation of interest under the Code) and payable upon such terms
as may be  prescribed  by the  Committee or (vi) allow  payment,  in whole or in
part,  through the  delivery of a notice that the  Optionee  has placed a market
sell order with a broker with  respect to shares of Common  Stock then  issuable
upon  exercise  of the  Option,  and that the broker has been  directed to pay a
sufficient  portion  of  the  net  proceeds  of  the  sale  to  the  Company  in
satisfaction  of the Option  exercise  price; or (vii) allow payment through any
combination of the consideration  provided in the foregoing  subparagraphs (ii),
(iii),  (iv), (v) and (vi). In the case of a promissory  note, the Committee may
also prescribe the form of such note and the security to be given for such note.
The Option may not be exercised, however, by delivery of a promissory note or by
a loan from the Company when or where such loan or other  extension of credit is
prohibited by law.

               5.3  Conditions  to Issuance of Stock  Certificates.  The Company
shall not be required to issue or deliver any  certificate or  certificates  for
shares of stock  purchased  upon the  exercise of any Option or portion  thereof
prior to fulfillment of all of the following conditions:

               (a) The  admission  of  such  shares  to  listing  on all  stock
exchanges on which such class of stock is then listed;

               (b) The completion of any registration or other  qualification of
such shares under any state or federal law, or under the rulings or  regulations
of the Securities and Exchange  Commission or any other governmental  regulatory
body which the Committee shall, in its discretion, deem necessary or advisable;

               (c) The  obtaining  of any approval or other  clearance  from any
state  or  federal  governmental  agency  which  the  Committee  shall,  in  its
discretion, determine to be necessary or advisable;

               (d) The lapse of such  reasonable  period of time  following  the
exercise  of the Option as the  Committee  may  establish  from time to time for
reasons of administrative convenience; and

               (e) The receipt by the Company of full  payment for such  shares,
including payment of any applicable withholding tax.

               5.4 Rights as Stockholders.  The holders of Options shall not be,
nor have any of the rights or  privileges  of,  stockholders  of the  Company in
respect of any shares  purchasable  upon the  exercise  of any part of an Option
unless and until  certificates  representing such shares have been issued by the
Company to such holders.

<PAGE>



               5.5 Ownership and Transfer  Restrictions.  The Committee,  in its
discretion, may impose such restrictions on the ownership and transferability of
the shares  purchasable upon the exercise of an Option as it deems  appropriate.
Any such  restriction  shall be set forth in the respective  Option Agreement or
other  agreement  between  the Company and the holders of such shares and may be
referred to on the  certificates  evidencing  such  shares.  The  Committee  may
require the Employee to give the Company  prompt  notice of any  disposition  of
shares of Common Stock acquired by exercise of an Incentive  Stock Option within
(a) two years from the date of granting  such Option to such Employee or (b) one
year after the  transfer  of such shares to such  Employee.  The  Committee  may
direct that the certificates evidencing shares acquired by exercise of an Option
refer to such requirement.


                                   ARTICLE VI

                                 ADMINISTRATION

               6.1 Compensation Committee. Prior to the closing of the Company's
initial  public  offering of Common  Stock (the  "Offering"),  the  Compensation
Committee  shall  consist  of the entire  Board.  Following  the  closing of the
Offering,  the Compensation Committee (or another committee or a subcommittee of
the Board assuming the functions of the Committee under this Plan) shall consist
solely of two or more Independent  Directors  appointed by and holding office at
the pleasure of the Board,  each of whom is (i) a  "non-employee  director"  (as
defined by Rule 16b-3), (ii) to the extent required by the applicable provisions
of Rule 16b-3,  a  "disinterested  person" as defined by Rule 16b-3 and (iii) an
"outside  director" for purposes of Section  162(m) of the Code.  Appointment of
Committee  members shall be effective upon acceptance of appointment.  Committee
members may resign at any time by delivering written notice to the Board.
Vacancies in the Committee may be filled by the Board.

               6.2 Duties and Powers of  Committee.  It shall be the duty of the
Committee to conduct the general  administration of this Plan in accordance with
its  provisions.  The Committee  shall have the power to interpret this Plan and
the  agreements  pursuant to which Options are granted,  and to adopt such rules
for the  administration,  interpretation,  and  application  of this Plan as are
consistent therewith and to interpret,  amend or revoke any such rules. Any such
grant under this Plan need not be the same with  respect to each  Optionee.  Any
such  interpretations and rules with respect to Incentive Stock Options shall be
consistent  with the  provisions of Section 422 of the Code. In its  discretion,
the Board may at any time and from time to time  exercise any and all rights and
duties of the  Committee  under this Plan except with  respect to matters  which
under Rule  16b-3 or Section  162(m) of the Code,  or any  regulations  or rules
issued  thereunder,  are required to be determined in the sole discretion of the
Committee.

               6.3 Majority Rule; Unanimous Written Consent. The Committee shall
act by a majority of its members in attendance at a meeting at which a quorum is
present or by a memorandum or other written  instrument signed by all members of
the Committee.

               6.4 Compensation;  Professional  Assistance;  Good Faith Actions.
Members of the Committee shall receive such  compensation  for their services as
members as may be determined by the Board.  All expenses and  liabilities  which
members of the Committee  incur in connection  with the  administration  of this
Plan shall be borne by the Company.  The Committee may, with the approval of the
Board, employ attorneys, consultants, accountants, appraisers, brokers, or other
persons.  The  Committee,  the Company and the Company's  officers and Directors
shall be entitled to rely upon the advice,  opinions or  valuations  of any such
persons. All actions taken and all interpretations and determi-

nations  made by the  Committee  or the Board in good  faith  shall be final and
binding upon all Optionees,  the Company and all other  interested  persons.  No
members of the  Committee  or Board shall be  personally  liable for any action,
determination or interpretation  made in good faith with respect to this Plan or
the  Options  and all  members  of the  Committee  and the Board  shall be fully
protected  by the  Company  in  respect  of any such  action,  determination  or
interpretation.

                                   ARTICLE VII

                            MISCELLANEOUS PROVISIONS

               7.1 Not  Transferable.  Options  under this Plan may not be sold,
pledged,  assigned,  or transferred in any manner other than by will or the laws
of descent and distribution or pursuant to a QDRO, unless and until such Options
have been exercised, or the shares underlying such Options have been issued, and
all restrictions applicable to such shares have lapsed. No Option or interest or
right therein  shall be liable for the debts,  contracts or  engagements  of the
Optionee or his or her successors in interest or shall be subject to disposition
by transfer, alienation,  anticipation,  pledge, encumbrance,  assignment or any
other means whether such disposition be voluntary or involuntary or by operation
of law  by  judgment,  levy,  attachment,  garnishment  or any  other  legal  or
equitable  proceedings  (including  bankruptcy),  and any attempted  disposition
thereof shall be null and void and of no effect,  except to the extent that such
disposition is permitted by the preceding sentence.

               During the lifetime of the  Optionee  only he or she may exercise
an Option (or any portion thereof) granted to him or her under the Plan,  unless
it has been disposed of pursuant to a QDRO. After the death of the Optionee, any
exercisable  portion  of an Option  may,  prior to the time  when  such  portion
becomes  unexercisable  under the Plan or the applicable  Option  Agreement,  be
exercised by his or her personal representative or by any person empowered to do
so under  the  deceased  Optionee's  will or under the then  applicable  laws of
descent and distribution.

               7.2 Amendment,  Suspension or Termination of this Plan. Except as
otherwise  provided in this  Section  7.2,  this Plan may be wholly or partially
amended or otherwise modified,  suspended or terminated at any time or from time
to  time  by the  Board  or the  Committee.  However,  without  approval  of the
Company's  stockholders given within twelve months before or after the action by
the Board or the Committee,  no action of the Board or the Committee may, except
as provided in Section 7.3,  increase  the limits  imposed in Section 2.1 on the
maximum number of shares which may be issued under this Plan or modify the Award
Limit,  and no action of the  Committee  or the  Board may be taken  that  would
otherwise require stockholder approval as a matter of applicable law, regulation
or rule. No amendment, suspension or termination of this Plan shall, without the
consent of the  holder of  Options,  alter or impair  any rights or  obligations
under any Options  theretofore  granted,  unless the applicable Option Agreement
itself  otherwise  expressly so provides.  No Options may be granted  during any
period of suspension or after  termination of this Plan, and in no event may any
Incentive  Stock  Option be granted  under this Plan after the first to occur of
the following events:

               (a) The expiration of ten years from the date the Plan is adopted
by the Board; or

               (b) The  expiration  of ten  years  from  the  date  the  Plan is
approved by the Company's stockholders under Section 7.4.

               7.3 Changes in Common Stock or Assets of the Company, Acquisition
or Liquidation of the Company and Other Corporate Events.

               (a) Subject to Section  7.3(d),  in the event that the  Committee
determines that any dividend or other distribution (whether in the form of cash,
Common  Stock,   other   securities,   or  other  property),   recapitalization,
reclassification,  stock split,  reverse  stock split,  reorganization,  merger,
consolidation,   split-up,  spin-off,  combination,   repurchase,   liquidation,
dissolution,  or  sale,  transfer,  exchange  or  other  disposition  of  all or
substantially all of the assets of the Company, (including, but not limited to a
Corporate  Transaction),  or exchange of Common Stock or other securities of the
Company,  issuance of warrants or other rights to purchase Common Stock or other
securities of the Company,  or other similar corporate  transaction or event, in
the  Committee's  sole  discretion,  affects  the  Common  Stock  such  that  an
adjustment is determined by the Committee to be  appropriate in order to prevent
dilution or  enlargement  of the benefits or potential  benefits  intended to be
made available  under the Plan or with respect to an Option,  then the Committee
shall, in such manner as it may deem equitable, adjust any or all of

               (i) the  number  and kind of  shares  of  Common  Stock (or other

        conditions as it deems appropriate, the Committee may provide, either by

to qualify as performance-based compensation under Section 162(m), no adjustment
or action  described in this  Section 7.3 or in any other  provision of the Plan

Plan to violate Section 422(b)(1) of the Code or would cause such Option to fail
to so  qualify  under  Section  162(m),  as the  case may be,  or any  successor
provisions  thereto.   Furthermore,  no  such  adjustment  or  action  shall  be
authorized to the extent such  adjustment or action would result in  short-swing
profits  liability under Section 16 of the Exchange Act or violate the exemptive
conditions of Rule 16b-3 unless the Committee  determines that the Option is not

for the approval of the  Company's  stockholders  within twelve months after the
date of the Board's initial adoption of this Plan.  Options may be granted prior
to  such  stockholder  approval,   provided  that  such  Options  shall  not  be
exercisable  prior to the time when this Plan is approved  by the  stockholders,

discretion and in satisfaction of the foregoing  requirement allow such Optionee
to elect to have the Company withhold shares of Common Stock otherwise  issuable
under such Option (or allow the return of shares of Common  Stock) having a Fair
Market Value equal to the sums required to be withheld.

constructively  received  by the  recipient  upon any receipt or exercise of the
Option or upon the receipt or resale of any Common Stock underlying such Option,

time period following  exercise of the Option,  or (b) the Optionee at any time,
or during a specified time period,  engages in any activity in competition  with
the Company,  or which is inimical,  contrary or harmful to the interests of the
Company, as further defined by the Committee.

Performance-Based  Compensation.  Notwithstanding  any other  provision  of this
Plan,  the Plan and any Option  granted to any individual who is then subject to
Section 16 of the  Exchange Act shall be subject to any  additional  limitations
set forth in any applicable  exemptive rule under Section 16 of the Exchange Act

requirements for the application of such exemptive rule. To the extent permitted
by  applicable  law,  the Plan and  Options  granted  hereunder  shall be deemed
amended to the extent  necessary to conform to such  applicable  exemptive rule.

forth in Section  162(m) of the Code  (including any amendment to Section 162(m)
of  the  Code)  or  any  regulations  or  rulings  issued  thereunder  that  are
requirements for qualification as performance-based compensation as described in
Section  162(m)(4)(C)  of the Code, and this Plan shall be deemed amended to the
extent necessary to conform to such requirements.

               7.9  Effect of Plan Upon  Options  and  Compensation  Plans.  The
adoption of this Plan shall not affect any other compensation or incentive plans
in effect  for the  Company  or any  Subsidiary.  Nothing  in this Plan shall be
construed to limit the right of the Company (a) to establish  any other forms of
incentives  or  compensation  for  Employees,  Directors or  consultants  of the

otherwise than under this Plan in connection with any proper  corporate  purpose

connection with the acquisition by purchase,  lease,  merger,  consolidation  or
otherwise,  of the business,  stock or assets of any  corporation,  partnership,
firm or association.

under Options  granted  hereunder are subject to compliance  with all applicable
federal  and state laws,  rules and  regulations  (including  but not limited to

                               EXERCISE OF OPTIONS

               5.1 Partial Exercise.  An exercisable  Option may be exercised in
whole or in part.  However,  an Option shall not be exercisable  with respect to
fractional  shares and the Board may  require  that,  by the terms of the Option
Agreement, a partial exercise be with respect to a minimum number of shares.

               5.2 Manner of Exercise. All or a portion of an exercisable Option
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his or her office:

               (a)  A  written  notice   complying  with  the  applicable  rules
established  by the Board  stating  that the Option,  or a portion  thereof,  is
exercised.  The notice  shall be signed by the  Optionee  or other  person  then
entitled to exercise the Option or such portion;

               (b) Such  representations and documents as the Board, in its sole
discretion,   deems  necessary  or  advisable  to  effect  compliance  with  all
applicable  provisions of the Securities Act, as amended,  and any other federal
or state securities laws or regulations.  The Board may, in its sole discretion,
also take  whatever  additional  actions  it deems  appropriate  to effect  such
compliance including, without limitation,  placing legends on share certificates
and issuing stop-transfer notices to agents and registrars;

               (c) In the event that the Option shall be  exercised  pursuant to
Section 7.1 by any person or persons other than the Optionee,  appropriate proof
of the right of such person or persons to exercise the Option; and

               (d) Full cash  payment to the  Secretary  of the  Company for the
shares  with  respect to which the Option,  or portion  thereof,  is  exercised.
However,  the Board,  may in its sole discretion (i) allow a delay in payment up
to thirty (30) days from the date the Option, or portion thereof,  is exercised;
(ii) allow  payment,  in whole or in part,  through  the  delivery  of shares of
Common Stock owned by the  Optionee,  duly  endorsed for transfer to the Company
with a Fair Market Value on the date of delivery equal to the aggregate exercise
price of the Option or exercised portion thereof;  (iii) allow payment, in whole
or in part,  through the  surrender of shares of Common Stock then issuable upon
exercise of the Option having a Fair Market Value on the date of Option exercise
equal  to the  aggregate  exercise  price of the  Option  or  exercised  portion
thereof;  (iv) allow  payment,  in whole or in part,  through  the  delivery  of
property of any kind which  constitutes  good and  valuable  consideration;  (v)
allow  payment,  in whole or in part,  through the  delivery of a full  recourse
promissory  note  bearing  interest  (at no less than  such  rate as shall  then
preclude the  imputation of interest under the Code) and payable upon such terms
as may be  prescribed by the Board or (vi) allow  payment,  in whole or in part,
through  the  delivery of a notice  that the  Optionee  has placed a market sell
order with a broker with  respect to shares of Common Stock then  issuable  upon
exercise  of the  Option,  and  that  the  broker  has  been  directed  to pay a
sufficient  portion  of  the  net  proceeds  of  the  sale  to  the  Company  in
satisfaction  of the Option  exercise  price; or (vii) allow payment through any
combination of the consideration  provided in the foregoing  subparagraphs (ii),
(iii),  (iv), (v) and (vi). In the case of a promissory note, the Board may also
prescribe the form of such note and the security to be given for such note.  The
Option may not be exercised,  however,  by delivery of a promissory note or by a
loan from the Company  when or where such loan or other  extension  of credit is
prohibited by law.

               5.3  Conditions  to Issuance of Stock  Certificates.  The Company
shall not be required to issue or deliver any  certificate or  certificates  for
shares of stock  purchased  upon the  exercise of any Option or portion  thereof
prior to fulfillment of all of the following conditions:

               (a)  The  admission  of  such  shares  to  listing  on all  stock

state  or  federal  governmental  agency  which  the  Board  shall,  in its sole
discretion, determine to be necessary or advisable;

               (d) The lapse of such  reasonable  period of time  following  the
exercise of the Option as the Board may establish  from time to time for reasons
of administrative convenience; and

               (e) The receipt by the Company of full  payment for such  shares,
including payment of any applicable withholding tax.

               5.4 Rights as Stockholders.  The holders of Options shall not be,

unless and until  certificates  representing such shares have been issued by the
Company to such holders.

               5.5 Ownership and Transfer  Restrictions.  The Board, in its sole
discretion, may impose such restrictions on the ownership and transferability of
the shares  purchasable upon the exercise of an Option as it deems  appropriate.
Any such  restriction  shall be set forth in the respective  Option Agreement or
other  agreement  between  the Company and the holders of such shares and may be
referred to on the certificates evidencing such shares.

               5.6  Limitations  on  Exercise  of  Options.  No  Option  may  be
exercised  to any  extent  by anyone  after the first to occur of the  following
events:

Optionee's death;

               (b) the  expiration  of twelve  (12)  months from the date of the

Optionee's  Termination  of  Directorship  by  reason of  removal  for cause (as
determined by the Board in its sole discretion);

               (d) the  expiration  of  thirty  (30)  days  from the date of the
Optionee's Termination of Directorship for any reason other than such Optionee's
death,  removal  for cause or his  permanent  and total  disability,  unless the
Optionee dies within said three-month period; or

granted.

                                 ADMINISTRATION

               6.1 Duties and Powers of Board. It shall be the duty of the Board
to  conduct  the  general  administration  of this Plan in  accordance  with its
provisions.  The  Board  shall  have the  power to  interpret  this Plan and the
agreements  pursuant to which  Options are granted,  and to adopt such rules for
the  administration,  interpretation,  and  application  of  this  Plan  as  are
consistent therewith and to interpret, amend or revoke any such rules.

               6.2 Majority Rule; Unanimous Written Consent. The Board shall act
by a majority  of its  members in  attendance  at a meeting at which a quorum is
present or by a memorandum or other written  instrument signed by all members of

               6.3 Professional Assistance; Good Faith Actions. All expenses and
liabilities   which  members  of  the  Board  incur  in   connection   with  the
administration of this Plan shall be borne by the Company.  The Board may employ

                                   ARTICLE VII

                            MISCELLANEOUS PROVISIONS

               7.1 Not  Transferable.  Options  under this Plan may not be sold,
pledged,  assigned,  or transferred in any manner other than by will or the laws
of descent and distribution or pursuant to a QDRO, unless and until such Options
have been exercised, or the shares underlying such Options have been issued, and
all  restrictions  applicable to such shares have lapsed.  No Option or interest
therein shall be liable for the debts,  contracts or engagements of the Optionee
or his or her  successors  in  interest  or shall be subject to  disposition  by
transfer, alienation, anticipation, pledge, encumbrance, assignment or any other
means whether such  disposition  be voluntary or  involuntary or by operation of
law by judgment,  levy, attachment,  garnishment or any other legal or equitable
proceedings (including bankruptcy),  and any attempted disposition thereof shall
be null and void and of no effect, except to the extent that such disposition is
permitted by the preceding sentence.

               During the lifetime of the  Optionee  only he or she may exercise
an Option (or any portion thereof) granted to him or her under the Plan,  unless
it has been disposed of pursuant to a QDRO. After the death of the Optionee, any
exercisable  portion  of an Option  may,  prior to the time  when  such  portion
becomes unexercisable under the Plan or the applicable Option Agreement or other
agreement,  be exercised by his or her personal  representative or by any person
empowered  to do so  under  the  deceased  Optionee's  will or  under  the  then
applicable laws of descent and distribution.

               7.2 Amendment,  Suspension or Termination of this Plan. Except as
otherwise  provided in this  Section  7.2,  this Plan may be wholly or partially
amended or otherwise modified,  suspended or terminated at any time or from time
to time by the Board. However, without approval of



                                              7

the Company's stockholders given within twelve months before or after the action
by the Board,  no action of the Board may,  except as provided  in Section  7.3,
increase the limits imposed in Section 2.1 on the maximum number of shares which
may be issued  under  this  Plan,  and no action of the Board may be taken  that
would  otherwise  require  stockholder  approval as a matter of applicable  law,
regulation or rule. No amendment,  suspension or termination of this Plan shall,
without  the  consent  of the  holder of  Options  alter or impair any rights or
obligations under any Options theretofore  granted,  unless the Option Agreement
itself  otherwise  expressly so provides.  No Options may be granted  during any
period of suspension or after termination of this Plan.

               7.3 Changes in Common Stock or Assets of the Company, Acquisition
or Liquidation of the Company and Other Corporate Events.

               (a)  Subject  to  Section  7.3(d),  in the  event  that the Board
determines that any dividend or other distribution (whether in the form of cash,
Common  Stock,   other   securities,   or  other  property),   recapitalization,
reclassification,  stock split,  reverse  stock split,  reorganization,  merger,
consolidation,   split-up,  spin-off,  combination,   repurchase,   liquidation,
dissolution,  or  sale,  transfer,  exchange  or  other  disposition  of  all or
substantially  all of the assets of the Company,  or exchange of Common Stock or
other  securities  of the  Company,  issuance  of  warrants  or other  rights to
purchase  Common  Stock or other  securities  of the Company,  or other  similar
corporate  transaction  or event,  in the Board's sole  discretion,  affects the
Common  Stock  such  that  an  adjustment  is  determined  by  the  Board  to be
appropriate  in order to prevent  dilution  or  enlargement  of the  benefits or
potential  benefits intended to be made available under the Plan or with respect
to an Option,  then the Board  shall,  in such manner as it may deem  equitable,
adjust any or all of

                    (i) the number and kind of shares of Common  Stock (or other
        securities  or property)  with  respect to which  Options may be granted
        under  the Plan  (including,  but not  limited  to,  adjustments  of the
        limitations in Section 2.1 on the maximum number and kind of shares),

                    (ii) the number and kind of shares of Common Stock (or other
        securities or property) subject to outstanding Options, and

                    (iii) the exercise price with respect to any Option.

               (b) Subject to Sections  7.3(b)(vi)  and 7.3(d),  in the event of
any Corporate  Transaction or other  transaction  or event  described in Section
7.3(a) or any  unusual or  nonrecurring  transactions  or events  affecting  the
Company,  any  affiliate  of the Company,  or the  financial  statements  of the
Company or any  affiliate,  or of changes in applicable  laws,  regulations,  or
accounting principles,  the Board in its sole discretion is hereby authorized to
take any one or more of the following actions whenever the Board determines that
such action is  appropriate  in order to prevent  dilution or enlargement of the
benefits or potential  benefits  intended to be made available under the Plan or
with respect to any Option under this Plan, to facilitate  such  transactions or
events or to give effect to such changes in laws, regulations or principles:

                    (i) In its sole discretion, and on such terms and conditions
        as it deems appropriate,  the Board may provide,  either by the terms of
        the Option  Agreement or by action taken prior to the occurrence of such
        transaction  or event and either  automatically  or upon the  Optionee's
        request,  for either the  purchase  of any such  Option for an amount of
        cash equal to the amount that could have been attained upon the exercise
        of such Option or realization  of the Optionee's  rights had such Option
        been currently  exercisable or the replacement of such Option with other
        rights or property selected by the Board;

                    (ii) In its sole discretion,  the Board may provide,  either
        by the terms of the Option  Agreement  or by action  taken  prior to the
        occurrence  of such  transaction  or event  that it cannot be  exercised
        after such event;

                    (iii) Subject to subsection (d), in its sole discretion, and
        on such  terms and  conditions  as it deems  appropriate,  the Board may
        provide,  either by the terms of such Option or by action taken prior to
        the occurrence of such transaction or event, that for a specified period
        of time  prior  to such  transaction  or  event,  such  Option  shall be
        exercisable as to all shares covered thereby,  notwithstanding  anything
        to  the  contrary  in (A)  Section  4.4 or  (B)  the  provisions  of the
        applicable Option Agreement;

                    (iv)  In  its  sole  discretion,   and  on  such  terms  and
        conditions as it deems appropriate, the Board may provide, either by the
        terms of such Option or by action taken prior to the  occurrence of such
        transaction  or event,  that upon such event,  such option be assumed by
        the  successor  or  survivor  corporation,  or a  parent  or  subsidiary
        thereof,  or shall be substituted  for by similar  options  covering the
        stock  of  the  successor  or  survivor  corporation,  or  a  parent  or
        subsidiary  thereof,  with appropriate  adjustments as to the number and
        kind of shares and prices; and

                    (v) In its sole discretion, and on such terms and conditions
        as it deems  appropriate,  the Board may make  adjustments in the number
        and type of shares of Common  Stock (or other  securities  or  property)
        subject to  outstanding  Options  and/or in the terms and  conditions of
        (including  the  exercise   price),   and  the  criteria   included  in,
        outstanding Options and Options which may be granted in the future.

                    (vi)  None  of the  foregoing  discretionary  terms  of this
        Section  7.3(b) shall be  permitted  to the extent that such  discretion
        would be inconsistent with the applicable  exemptive  conditions of Rule
        16b-3.  In the event of  Corporate  Transaction,  to the extent that the
        Board does not have the  ability  under Rule 16b-3 to take or to refrain
        from taking the discretionary  actions set forth in Section  7.3(b)(iii)
        above, each Option shall be exercisable as to all shares covered thereby
        during the five days  immediately  preceding  the  consummation  of such
        Corporate Transaction and subject to such consummation,  notwithstanding
        anything to the contrary in Section 4.4 or the vesting  schedule of such
        Options. In the event of a Corporate Transaction, to the extent that the
        Board does not have the  ability  under Rule 16b-3 to take or to refrain
        from taking the  discretionary  actions set forth in Section  7.3(b)(ii)
        above, no Option may be exercised  following such Corporate  Transaction
        unless such Option is, in connection  with such  Corporate  Transaction,
        either  assumed by the successor or survivor  corporation  (or parent or
        subsidiary  thereof) or replaced with a comparable right with respect to
        shares of the capital stock of the successor or survivor corporation (or
        parent or subsidiary thereof).

               (c) Subject to Section 7.3(d) and 7.8, the Board may, in its sole
discretion,  include  such  further  provisions  and  limitations  in any Option
Agreement as it may deem equitable and in the best interests of the Company.

               (d) No adjustment  or action  described in this Section 7.3 or in
any other  provision  of the Plan shall be  authorized  to the extent  that such
adjustment or action would result in short-swing profits liability under Section
16 of the Exchange Act or violate the exemptive  conditions of Rule 16b-3 unless
the  Board  determines  that the  Option is not to  comply  with such  exemptive
conditions.  The number of shares of Common  Stock  subject to any Option  shall
always be rounded to the next whole number.

               7.4 Approval of Plan by Stockholders. This Plan will be submitted
for the approval of the  Company's  stockholders  within twelve months after the
date of the Board's initial adoption of this Plan.  Options may be granted prior
to  such  stockholder  approval,   provided  that  such  Options  shall  not  be
exercisable  prior to the time when this Plan is approved  by the  stockholders,
and provided  further that if such  approval has not been obtained at the end of
said twelve-month  period,  all Options previously granted under this Plan shall
thereupon be cancelled and become null and void.

               7.5 Tax  Withholding.  The  Company  shall be entitled to require
payment in cash or deduction from other compensation payable to each Optionee of
any sums required by federal, state or local tax law to be withheld with respect
to the issuance or exercise of any Option.  The Board may in its sole discretion
allow such Optionee to elect to have the Company withhold shares of Common Stock
otherwise  issuable  under such  Option (or allow the return of shares of Common
Stock) having a Fair Market Value equal to the sums required to be withheld.

               7.6 Loans. The Board may, in its sole  discretion,  extend one or
more loans to Independent Directors in connection with the exercise of an Option
granted under this Plan.  The terms and conditions of any such loan shall be set
by the Board.

               7.7 Forfeiture  Provisions.  Pursuant to its general authority to
determine  the  terms  and  conditions  applicable  to  Options  under  the Plan
consistent  with the  provisions of the Plan, the Board shall have the right (to
the extent consistent with the applicable exemptive conditions of Rule 16b-3) to
provide,  in the terms of Options  granted  under the Plan,  or to  require  the
recipient to agree by separate written instrument,  that (a) any proceeds, gains
or other economic benefit actually or  constructively  received by the recipient
upon any  receipt or exercise of the Option or upon the receipt or resale of any
Common Stock  underlying  such Option must be paid to the  Company,  and (b) the
Option  shall  terminate  and any  unexercised  portion of such Option  shall be
forfeited,  if (i) the Optionee incurs a Termination of Directorship  prior to a
specified date, or within a specified time period following  receipt or exercise
of the  Option,  or (ii) the  Optionee at any time,  or during a specified  time
period,  engages in any activity in  competition  with the Company,  or which is
inimical,  contrary  or  harmful to the  interests  of the  Company,  as further
defined by the Board.

               7.8 Limitations Applicable to Section 16 Persons. Notwithstanding
any other  provision  of this  Plan,  this Plan and any  Option  granted  to any
individual  who is then  subject  to  Section  16 of the  Exchange  Act shall be
subject to any additional limitations set forth in any applicable exemptive rule
under Section 16 of the Exchange Act  (including  any amendment to Rule 16b-3 of
the Exchange Act) that are  requirements  for the  application of such exemptive
rule. To the extent  permitted by applicable  law, the Plan and Options  granted
hereunder  shall be deemed  amended to the extent  necessary  to conform to such
applicable exemptive rule.

               7.9  Effect of Plan Upon  Options  and  Compensation  Plans.  The
adoption of this Plan shall not affect any other compensation or incentive plans
in effect  for the  Company  or any  Subsidiary.  Nothing  in this Plan shall be
construed to limit the right of the Company (a) to establish  any other forms of
incentives  or  compensation  for  Employees,  Directors or  consultants  of the
Company or any  Subsidiary  or (b) to grant or assume  options  or other  rights
otherwise than under this Plan in connection with any proper  corporate  purpose
including  but not by way of  limitation,  the grant or assumption of options in
connection with the acquisition by purchase,  lease,  merger,  consolidation  or
otherwise,  of the business,  stock or assets of any  corporation,  partnership,
firm or association.

               7.10 Compliance with Laws. This Plan, the granting and vesting of
Options  under this Plan and the issuance and delivery of shares of Common Stock
under Options granted hereunder are


                                              10

regulations  (including but not limited to state and federal  securities law and
federal margin requirements) and to such approvals by any listing, regulatory or

necessary or advisable in connection  therewith.  Any securities delivered under
this Plan shall be subject to such  restrictions,  and the person acquiring such
securities  shall,  if  requested by the Company,  provide such  assurances  and
representations to the Company as the Company may deem necessary or desirable to
assure  compliance  with  all  applicable  legal  requirements.  To  the  extent
permitted by applicable law, the Plan and the Options granted hereunder shall be
deemed  amended to the  extent  necessary  to  conform  to such laws,  rules and
regulations.

are not to serve as a basis for interpretation or construction of this Plan.

               7.12 Governing Law. This Plan and any agreements  hereunder shall
be  administered,  interpreted and enforced under the internal laws of the state
of New York without regard to conflicts of laws thereof.

diligent  program for  exploitation of the Patent Rights and to continue active,

Processes throughout the life of this Agreement.  In particular,  Licensee shall
diligently  pursue  product  development,   FDA  regulatory   approval,   market
introduction of the product after FDA approval and continued sales support.  The
ongoing  Research  Agreement  between  the  parties  shall be deemed  sufficient
evidence of  diligence  in product  development.  Thereafter,  or if no Research

development  project leading to market  introduction  will be deemed  sufficient
evidence of diligence.

within 12 months of receiving  FDA approval  and shall  continuously  thereafter
offer Licensed Products for sale.

        3.3  Licensee's  failure to perform in accordance  with Sections 3.1 and
3.2 above shall be grounds for University to terminate  this Agreement  pursuant
to Section 13.3 hereof.

                      65 percent (65%) of product  development costs, as defined
                      in Section 10 of the Research Agreement of January 2, 1993
                      as amended or in any subsequent Research Agreement.

               (b)    Royalties  in an  amount  equal  to *** of net  sales  for
                      Licensed Products for which University  provides less than
                      sixty-five percent (65%) but more than thirty-five percent
                      (35%) of product  development costs, as defined in Section
                      10 of the Research Agreement of January 2, 1993 as amended
                      or in any subsequent Research Agreement.

               (c)    Royalties  in an  amount  equal  to *** of net  sales  for
                      Licensed Products for which University  provides less than
                      thirty-five percent (35%) of product development costs, as
                      defined in section 10 of the Research Agreement of January
                      2,  1993  as  amended  or  in  any   subsequent   Research
                      Agreement.

               (d)    Royalties  in an  amount  equal  to *** of net  sales  for
                      Licensed   Products  if  no  Research   Agreement  between
                      University and Licensee is then in effect.

               (e)    If the Licensed  Product is combined  with a drug or other
                      substance  and/or any device for which  Licensee is paying
                      an  additional  royalty,  the  royalty

                      rates set forth in subsections  (a), (b), (c), (d) and (e)
                      shall be reduced by the percentage rate Licensee is paying
                      as  additional  royalty,  provided  that in no event shall
                      University  receive  less  than 50  percent  (50%)  of the
                      royalty rates set forth in subsections  (a), (b), (c), (d)
                      and (e).

        4.2 All payments due hereunder shall be paid in full,  without deduction
of taxes or other fees which may be imposed by any government and which shall be
paid by Licensee.

        4.3 No multiple royalties shall be payable because any Licensed Product,
its  manufacture,  use,  lease or sale are or shall be  covered by more than one
Patent Rights patent  application  or Patent Rights patent  licensed  under this
Agreement.

        4.4 Royalty payments shall be paid in United States dollars in Richmond,
Virginia,  or at  such  other  place  as  University  may  reasonably  designate
consistent with the laws and regulations  controlling in any foreign country. If
any  currency  conversion  shall be required in  connection  with the payment of
royalties  hereunder,  such conversion  shall be made by using the exchange rate
prevailing  at the Chase  Manhattan  Bank (N.A.) on the last business day of the
calendar quarterly reporting period to which such royalty payments relate.


                             5 - REPORTS AND RECORDS

        5.1  Licensee  shall  keep  full,  true and  accurate  books of  account
containing all particulars  that may be necessary for the purpose of showing the
amounts payable to University hereunder.  Said books of account shall be kept at
Licensee's principal place of business or the principal place of business of the
appropriate division of Licensee to which this Agreement relates. Said books and
the  supporting  data shall be open at all  reasonable  times for five (5) years
following the end of the calendar year to which they pertain,  to the inspection
of  University  or its agents for the purpose of  verifying  Licensee's  royalty
statement or  compliance  in other  respects  with this  Agreement.  Should such
inspection lead to the discovery of a greater than ten percent (10%) discrepancy
in reporting to University's detriment,  Licensee agrees to pay the full cost of
such inspection.

        5.2 After the first  commercial  sale of a Licensed  Product or Licensed
Process,  Licensee, within sixty (60) days after March 31, June 30, September 30
and December 31, of each year,  shall  deliver to  University  true and accurate
reports,  giving such particulars of the business  conducted by Licensee and its
sublicensees  during the preceding  three-month  period under this  Agreement as
shall be pertinent to a royalty  accounting  hereunder.  These shall  include at
least the following:

               (a)    number  of  Licensed  Products  manufactured  and  sold by
                      Licensee and all sublicensees;

               (b)    total billings for Licensed  Products sold by Licensee and
                      all sublicensees;



                                             5




<PAGE>
<PAGE>



               (c)    accounting  for  all  Licensed  Processes  used or sold by
                      Licensee and all sublicensees;

               (d)    deductions applicable as provided in Section 1.5;

               (e)    total royalties due; and

               (f)    names and addresses of all sublicensees of Licensee.

        5.3 With each such report  submitted,  Licensee  shall pay to University
the  royalties due and payable under this  Agreement.  If no royalties  shall be
due, Licensee shall so report.

        5.4 On or  before  the  ninetieth  (90th)  day  following  the  close of
Licensee's  fiscal year,  Licensee  shall  provide  University  with  Licensee's
certified  financial  statements for the preceding  fiscal year including,  at a
minimum, a Balance Sheet and an Operating Statement.

        5.5 The royalty  payments  set forth in this  Agreement  and amounts due
under Section 6 shall,  if overdue,  bear interest  until payment at a per annum
rate one percent (1%) above the prime rate in effect at the Chase Manhattan Bank
(N.A.)  on the due date.  The  payment  of such  interest  shall  not  foreclose
University  from exercising any other rights it may have as a consequence of the
lateness of any payment.


                             6 - PATENT PROSECUTION

        6.1  Licensee,  at its own expense and utilizing  patent  counsel of its
choice,  mutually  agreeable  to  University,  shall  have  the sole  right  and
responsibility  for the  filing,  prosecution,  and  maintenance  of any  patent
applications and patents contained in the Patent Rights.  University and counsel
of its choice,  agreeable to Licensee,  shall have the right of prior review and
approval  of all  documents  to be  filed  with the  United  States  Patent  and
Trademark  Office  or any  foreign  patent  office or  patent  agent.  Licensee,
therefore,  shall provide draft copies of any such document to University within
a reasonable time (not fewer than ten (10) business days) before the anticipated
filing date.  Licensee,  or its patent  counsel,  shall provide  University with
copies of all  correspondence  and documents  filed with, or received  from, the
United States Patent 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 SHALL be forwarded to, and retained BY, University.

        6.2  University  shall have the right,  but not an  obligation  to file,
prosecute or maintain any United States or foreign patent  application or patent
contained  in the Patent  Rights if Licensee  elects not to file,  prosecute  or
maintain such patent  applications  or patents.  Licensee shall promptly  notify
University  in writing of its decision not to file,  prosecute or maintain  such
patent applications or patents.

        6.3 Licensee shall be responsible for all future expenses related to the
filing, prosecution, and maintenance of patent applications and patents directly
related to the Patent Rights.


                       7 - INFRINGEMENT AND OTHER ACTIONS

        7.1 Licensee and University  shall promptly  provide written notice,  to
the other  party,  of any  alleged  infringement  by a third party of the Patent
Rights  and  provide  such  other  party  with any  available  evidence  of such
infringement.

        7.2 During the term of this  Agreement,  Licensee  shall have the right,
but not the  obligation,  to  prosecute  and/or  defend,  at its own expense and
utilizing  counsel of its choice,  any infringement of, and/or challenge to, the
Patent  Rights.  In  furtherance  of such right,  University  hereby agrees that
Licensee may join  University  as a party in any such suit,  without  expense to
University. **** Licensee shall indemnify University against any order for costs
that may be made against University in any such suit.

        7.3 In the event that Licensee shall  undertake the  enforcement  and/or
defense of the Patent Rights by  litigation,  Licensee may withhold up to *** of
the payments  otherwise  thereafter due University under Section 4 hereunder and
apply the same toward reimbursement of Licensee's expenses, including reasonable
attorneys,  fees, in connection  therewith.  Any recovery of damages by Licensee
for each such suit shall be applied first in  satisfaction  of any  unreimbursed
expenses  and legal fees of  Licensee  relating  to such suit,  and next  toward
reimbursement  of  University  for any  payments  under  Section  4 past  due or
withheld and applied pursuant to this Section 7.

        7.4 If Licensee  elects not to defend any action  referred to in Section
7.2,  above,  it shall so notify  University  in writing  immediately.  Prior to
providing  such  notification  to  University,  Licensee  shall  take any action
necessary to ensure that rights of the University  under any such action are not
prejudiced,  including  but not  limited  to  filing a  responsive  pleading  or
obtaining an extension of time to do so.  University may elect, but shall not be
obligated,  to defend any action  referred to in Section 7.2,  above, at its own
expense using counsel of its choice and  University may join Licensee as a party
in such suit at no expense to  Licensee.  University  may keep any  recovery  or
damages which may be derived from its defense.

        7.5 If within  six (6)  months  after  receiving  notice of any  alleged
infringement,  Licensee shall have been  unsuccessful  in persuading the alleged
infringer  to  desist,  or shall not have  brought  and shall not be  diligently
prosecuting an infringement  action, or if Licensee shall notify University,  at
any time prior  thereto,  of its intention not to bring suit against the alleged
infringer,  then, and in those events only, University shall have the right, but
not the obligation,  to prosecute,  at its own expense and utilizing  counsel of
its choice,  any action for  infringement  of the Patent Rights,  and University
may, for such purposes,  join the Licensee as a party plaintiff.  The total cost
of any such infringement action commenced solely by University shall be borne by
University  and  University   shall  keep  any  recovery  or  damages  for  past
infringement derived therefrom.

        7.6 In the event that a declaratory  judgment action alleging invalidity
or infringement  of any of the Patent Rights shall be brought against  Licensee,
University,  at its option,  shall have the right, within thirty (30) days after
commencement of such action,  to intervene and take over the sole defense of the
action at its own expense.

        7.7 In any suit to enforce  and/or defend the Patent Rights  pursuant to
this  License  Agreement,  the party not in control of such suit  shall,  at the
request and expense of the controlling party,  cooperate in all respects and, to
the  extent  possible,  have  its  employees  testify  when  requested  and make
available relevant records,  papers,  information,  samples,  specimens, and the
like.


                              8 - PRODUCT LIABILITY

        8.1 University, by this License Agreement, makes no representation as to
the  patentability  and/or  breadth of the  inventions  contained  in the Patent
Rights.  University,  by this License  Agreement makes no  representation  as to
patents  now held or which  will be held by others in the field of the  Licensed
Products  for a particular  purpose  except as set forth in Section 14.5 of this

filed or otherwise  instituted against the Indemnified  Parties related directly
or indirectly to or arising out of the design, manufacture,  sale, or use of the
Licensed  Products or Licensed  Processes  by  Licensee or its  Affiliates  even
though such claims, causes of action,  lawsuits, other proceedings and the costs
(including  attorney's fees) related thereto result in whole or in part from any
act or failure to act, other than willful misconduct or gross negligence, of any
of the Indemnified  Parties.  University  agrees to be responsible,  where found
liable an to t e extent covered by insurance or specified by statute,  whichever
is lower, for the payment of any or all claims for loss, personal injury, death,
property damage or otherwise arising out of any act or omission of its employees

agencies,  institutions,  and employees are covered by a self insured plan based

(including, but not limited to, breach or default under Section 3-3), other than

referred to in this Section 11.3,  University  shall have the right to terminate
this  Agreement  and  the  rights,  privileges  and  license  granted  hereunder

prior to the effective date of such termination; and Sections 1, 8, 9, 10, 11.5,

All other terms and conditions of the agreement shall remain the same.

        Licensee  shall pay  royalties to  University in an amount equal to ****
        Licensee's Net Sales for Licensed Products.

               (b) If Licensee  enters into  sublicensing  agreements,  Licensee
        shall pay  University a percentage of all  royalties  received from such
        sublicensees  as set  forth  below,  including  advances  on  royalties,

data shall be open at all reasonable times for three (3) years following the end

ARTICLE 7 - INFRINGEMENT AND OTHER ACTIONS

Replace Section 7.6 with the following:

        In the event that a declaratory  judgment action alleging  invalidity of
        any of the Patent Rights shall be brought against Licensee, Licensee (or
        a  sublicensee),  shall have the right to assume the sole defense of the
        action  at its own  expense,  provided  that at the time the  action  is
        brought a Licensed  Product covered by such Patent Rights is in clinical
        development or being  commercialized by Licensee or its sublicensee.  In
        such event,  University  shall have the right to approve  Licensee's (or
        its  sublicensee's)  choice  of  counsel,  which  approval  shall not be
        unreasonably  withheld or  delayed.  If  Licensee  (or its  sublicensee)
        elects not to assume such defense,  or if no such product is in clinical
        development or being commercialized, University at its option shall have
        the right, within thirty (30) days after commencement of such action, to
        intervene  and assume the sole defense of the action at its own expense.
        If  University  does not elect to assume  such  sole  defense,  it shall
        notify  Licensee,  which  may then  assume  such  defense  if it did not
        previously have the right to do so (e.g.,  because no such product is in
        clinical development).

Add the following at the end of Section 7.7: "All rights of Licensee  under this
Article 7 may be granted to sublicensees,  and to such extent  University agrees
to perform its obligations  hereunder for the benefit of sublicensees as if they
were Licensee.

ARTICLE 8 - PRODUCT LIABILITY

In Section  8.1,  change the cross  reference  from  "Section  14.5" to "Section
13.5."

ARTICLE 10 - ASSIGNMENT

Add the  following  to the end of the first  sentence  of Section 10: "or to any
successor by merger or  acquisition  of all or  substantially  all of Licensee's
business unit to which this Agreement relates."

ARTICLE 11 - TERMINATION

Amend Section 11.6 to read in its entirety:


        Upon  termination of this Agreement for any reason,  any sublicensee not
        then in  default  of the  sublicense  shall  have the  right to obtain a
        direct  license  from  University  under the same  terms and  conditions
        contained  in  the   sublicense   agreement;   provided  that  (a)  such
        sublicensee's  prior satisfaction of any obligation under the sublicense
        agreement shall be deemed a satisfaction  of the same  obligation  under
        the  direct  license;  (b) such a license  will  contain a  commercially
        reasonable   obligation  to  diligently   develop  and  market  Licensed
        Products; provided, however, that any such obligation shall be fulfilled
        if the

<PAGE>
<PAGE>




        licensee (the former  sublicensee) agrees to pay minimum royalties of at
        least **** per year for the 10 years commencing one year after the first
        Licensed  Product  receives  regulatory  approval  so long as there is a
        valid,  issued  U.S.  patent  within the Patent  Rights;  and (c) such a
        license shall include the terms of Article 8 of this Agreement.

Add a new Section 11.7 to read:

               11.7 This Agreement  shall commence on august 16, 1993 and expire
        on the date the last patent  application within the Patent Rights expire
        or is invalidated,  or is abandoned or disclaimed (which period shall be
        the "term" of this Agreement).

ARTICLE 13 - MISCELLANEOUS PROVISIONS

At the beginning of Section 13.5,  after the phrase "as of the date hereof," add
the phrase "and the date of execution of Modification No. 3 of this Agreement."

In Section 13.5(c),  replace the phrase "Specified Technologies" with the phrase
"Patent  Rights."  In the same  section,  replace  the  phrase  "subject  to any
required royalty-free  non-exclusive government license pursuant to NIH funding"
with the phrase "subject to any government rights arising out of general funding
provided to University  (excluding funding provided under a `funding agreement',
as defined  in 35 U.S.C.  201(b),  applicable  to the work  conducted  under the
Research  Agreement between University and Licensee dated January 2, 1993 or the
one dated December 15, 1993 (the `Research Agreements'))."

At the end of Section 13.5, add the following:

        , (f)  neither the  University  nor any of its  researchers,  faculty or
        students  have any  rights  or  interest  in any  know-how,  technology,
        information  or patent rights which may be necessary for the practice of
        the  license  granted  in  this  Agreement,  (g) no  federal  government
        "funding  agreement,"  as  defined  in  35  U.S.C.  201(b),  is  or  was
        applicable to the work conducted  under the Research  Agreements and (h)
        all patent rights arising out of the Research Agreements are licensed to
        Licensee pursuant to this Agreement.  University agrees that it will not
        assert against  Licensee or any  sublicensee any claim based upon rights
        to unpatented  know-how or information  pertaining to the subject matter
        of the Patent Rights.

Add a new Section 13.8 to read:

               13.8 Each party  agrees  that it shall not  disclose to any third
        party (other than an agent, a sublicensee or potential  sublicensee) any
        patent,  royalty or other commercial  information  provided by the other
        party pursuant to this Agreement (including any information contained in
        sublicense  agreements),  except with the prior  written  consent of the
        disclosing  party.  Each party  agrees  not to use any such  information
        except for the purpose of performing under this Agreement.

                                LICENSE AGREEMENT

        THIS  AGREEMENT  is by and  between  ALGOS  PHARMACEUTICAL  CORPORATION,

COMPANY,  a division of  McNeil-PPC,  Inc.,  having an address at 7050 Camp Hill
Road, Fort Washington, Pennsylvania 19034 (hereinafter referred to as "McNEIL").

                                   WITNESSETH

        WHEREAS,  Virginia  Commonwealth  University  ("VCU")  is the  owner  of
certain patents and patent applications  relating to use of NMDA Antagonists (as
hereinafter defined) for the treatment of pain;

        WHEREAS,   ALGOS  collaborated  with  VCU  in  the  development  of  the
technology  claimed in such patents and patent  applications and has exclusively
licensed from VCU such patent and patents applications under the VCU License (as
hereinafter defined);

        WHEREAS,  ALGOS has also developed  proprietary know-how relating to the
use of NMDA Antagonists for the treatment of pain; and

        WHEREAS,  McNEIL wishes to acquire an exclusive license from ALGOS under
such patents,  patent  applications and know-how,  and ALGOS is willing to grant
such license to McNEIL under the terms and conditions of this Agreement.

        NOW,  THEREFORE,  in  consideration  of the above premises and covenants
contained herein, the parties agree as follows:

                                       1

controls,  is  controlled  by or is under  common  control  with a party to this
Agreement,  and for such purpose "control" shall mean the possession,  direct or
indirect, of the power to direct or cause the direction of the management or the
policies of the entity,  whether through the ownership of voting securities,  by
contract or otherwise.

        1.4.  ALGOS KNOW-HOW shall mean all  information,  trade secrets,  data,

sublicense)  to ALGOS,  prior to or during the term of this Agreement (a listing
of those  presently  known is identified in Schedule A, which is attached hereto
and made a part of this Agreement and which shall promptly be updated by ALGOS),
any   foreign   counterparts    thereof,   as   well   as   all   continuations,
continuations-in-part,  divisions and renewals thereof, all patents which may be
granted  thereon,  and  all reissues,  re-examinations,  extensions,  patents of
additions and patents of importation thereof.

        1.6.  ALGOS  RIGHTS  shall  mean the ALGOS  Patent  Rights and the ALGOS
KNOW-HOW.

        1.7.   EFFECTIVE DATE of this Agreement shall mean ______________, 1996.

successor bodies or corresponding foreign administrative bodies.

        1.9.  FIELD shall mean the methods and/or  compositions  for the making,
using and selling of NMDA Antagonist in combination with  Acetaminophen or NSAID
* * * for the  treatment of pain.  "Field" may be narrowed  pursuant to Sections

        1.10.  FIRST  COMMERCIAL  SALE shall mean the first sale by McNEIL,  its
Affiliates or sublicensees of a Licensed  Product to an independent  third party
in the Territory.

        1.11.  FISCAL  QUARTER  shall mean each of the  periods of time  between

exemplified by Schedule G attached hereto.

        1.12. FISCAL YEAR shall mean the period of time commencing on the Monday
following  the Sunday  closest to the end of the calendar  month of December and
terminating  on the  Sunday  closest  to the end of the  immediately  succeeding

regular course of business.

        1.13. LICENSED PRODUCT shall mean any product in the Field which employs
ALGOS  KNOW-HOW or which would infringe a Valid Claim of ALGOS Patent Rights but
for the licenses granted herein.  The parties agree that all products  developed
or marketed by McNEIL during the term of this  Agreement  which  comprise one or
more NMDA Antagonists in combination with  Acetaminophen or an NSAID and include
claims  for  or  are  marketed  for  the  analgesia  enhancing  effect  of  NMDA
Antagonists fall within ALGOS KNOW-HOW.

        1.14. NDA shall mean a New Drug Application or any other  application or
procedure  required  to seek  approval  from  the  FDA to  allow  McNEIL  or its
Affiliates  or  sublicensees  to sell  Licensed  Product in the United States or
other countries.

        1.15.  NET SALES shall mean the total  revenue  received by McNEIL,  its
Affiliates  or  sublicensees  from the sale of Licensed  Product to  independent
third parties less the following amounts: * * * * * * * * * * * * * * * * * * *

* * * * * * * * * * * * * * *

        In the event the sale described  above is of Licensed  Product in a form
other than the final dosage form appropriate for human  consumption or use, then
the parties shall mutually  determine in good faith an adjustment to the royalty
provisions  contained in this Agreement  designed to  approximate  the aggregate
royalty payment that would have been due to ALGOS had such sale been of Licensed
Product in final dosage form.  Such  adjustment  will not provide for  royalties
greater  than  that  otherwise  due  hereunder  on the  same  volume  of  active
ingredient in final dosage form as sold in the market of final destination.

        In the event that  Licensed  Product is sold in the form of a package or
kit  containing  one or more products  other than Licensed  Product (a "Packaged
Product"), Net Sales for such Packaged Product will be calculated by multiplying
actual Net Sales of such Packaged Product by the fraction A/(A+B) where A is the
invoice  price  of the  Licensed  Product  if sold  separately  by  McNEIL,  its
Affiliates or  sublicensees  and B is the total invoice price of the one or more
other  products in the  Packaged  Product,  if sold  separately  by McNEIL,  its
Affiliates  or  sublicensees,  in  each case on a country-by-country  basis.  If
Licensed  Product is provided in a Packaged  Product as a sample (i.e.,  six (6)
dosage  units or less)  then such  shall not be  considered  a sale of  Licensed
Product.

        If, on a country-by-country basis, the one or more other products in the
Packaged  Product  are not sold  separately  in said  country  by  McNEIL or its
Affiliates  or  sublicensees,  Net  Sales  for such  Packaged  Product  shall be
calculated  by  multiplying  actual  Net Sales of such  Packaged  Product by the
fraction  A/C  where A is the  invoice  price of the  Licensed  Product  if sold
separately by McNEIL, its Affiliates or sublicensees, and C is the invoice price
of the  Packaged  Product,  if sold  separately  by McNEIL,  its  Affiliates  or
sublicensees.

        If, on a  country-by-country  basis,  the  Licensed  Product is not sold
separately in said country by McNEIL, its Affiliates,  or its sublicensees,  Net
Sales for such Packaged  Product  shall be  calculated  as provided  immediately
above except that A shall be the fair market value of the Licensed Product and C
shall be the fair market value of the Packaged  Product.  If the parties  cannot
agree on such fair market  values  within  forty-five  (45) days of a request by
either party that such values be determined, then such

                                       4

question  shall be resolved  by an  independent  industry  expert as provided in
Section 13.1.

N-methyl-D-aspartate receptor,* * * * * * * * * * * * * * * * * * * * * * * * *

* * * * * * * * * * * * * * *

        1.17.  NSAID shall mean any of ibuprofen * * * and mixtures,  isomers or
pharmaceutically  acceptable  salts thereof,  alone or in  combination  with any
other ingredient or ingredients other than an anesthetic or any other analgesic.
If  McNEIL is in active  human  clinical  development  with a  Licensed  Product
containing ibuprofen * * * or a mixture,  isomer or pharmaceutically  acceptable
salt thereof,  in combination with another  ingredient not then approved for use
as an analgesic or anesthetic  by FDA in the U.S.,  Japan,  the United  Kingdom,
Germany,  France,  Sweden, Italy or the Netherlands,  then McNEIL's rights under
this  Agreement to pursue such  Licensed  Product  shall  continue  even if such
ingredient is later approved for such use by FDA in one of the above countries.

        1.18. NSAID MILESTONE PATENT shall mean the first patent to issue in the
U.S.  included in ALGOS Patent Rights  containing  Valid  Claim(s) that would be
infringed by all embodiments  within the scope of milestone claim B set forth in
Schedule D.

        1.19.  PATENTED  PRODUCT shall mean any product in the Field wherein its
making,  using or  selling by  McNEIL,  its  Affiliates  or  sublicensees  would
infringe  a Valid  Claim of ALGOS  Patent  Rights but for the  licenses  granted
herein.

        1.20. PHASE III CLINICAL  TRIAL(S) shall mean that portion of a clinical
development program which provides for trials of a product on sufficient numbers
of patients to  establish  the safety and  efficacy of a product for the desired
claims  and  indications.  The  trials may  involve  several  hundred to several
thousand  patients enrolled at several sites and may include both controlled and
uncontrolled studies.

        1.21.  REGULATORY MARKETING EXCLUSIVITY shall mean the initial exclusive
rights  for  McNEIL to market a  particular  Licensed  Product  in a country  or
jurisdiction  within  the  Territory,   as  provided  by  regulatory  action  or
protection by the FDA, where such  exclusivity  derives from the  combination of
Acetaminophen  or an  NSAID  with  an  analgesia  enhancing  amount  of an  NMDA
Antagonist.  The parties agree that in the United States such  exclusive  rights
shall  mean  the  first  time  period  provided  by any  grant  of  Hatch-Waxman
exclusivity.

        1.22.  TERRITORY shall mean the world.

                                      5

        1.23.  U.S.  shall mean the United States of America  (including  Puerto
Rico) and its territories and possessions.

        1.24.  VALID CLAIM shall mean a claim in any  unexpired,  issued  patent
within the ALGOS Patent Rights which has not been held invalid or  unenforceable
by a non- appealed or unappealable decision by a court or other appropriate body
of  competent  jurisdiction,  and which is not  admitted  to be invalid  through
disclaimer or dedication to the public.

        1.25.  VCU LICENSE  shall mean the License  Agreement of August 16, 1993

                                 GRANT OF RIGHTS

        2.1.  Subject  to Section  2.2,  ALGOS  hereby  grants to McNEIL and its
Affiliates an exclusive license under ALGOS Rights to make, have made, use, sell
and  have  sold  products  in the  Field  in the  Territory.  McNEIL  may  grant
sublicenses without restriction to non-Affiliates which McNEIL or its Affiliates
routinely  use  as  distributors  in  foreign  countries  and  to  international
pharmaceutical  companies having a well  established over the counter  analgesic
pharmaceutical franchise.  Neither McNEIL, its Affiliate nor any sublicensee may
grant a  sublicense  to any other  third  party  except  with the prior  written
consent of ALGOS,  which consent shall not be unreasonably  withheld or delayed.
McNEIL  shall  require all  sublicensees  to make  payments to ALGOS on the same
terms applicable to McNEIL under Articles 3 and 4 of this Agreement.

        2.2.

               2.2.1.  McNEIL acknowledges that VCU has retained the right under

licensees  outside the Field are excluded  from McNEIL's  license  hereunder and
reserved to ALGOS.  McNEIL  covenants that it will not practice the ALGOS Rights
in any manner except to make, have made, use, sell and have sold products in the
Field in the Territory.

               2.2.3.  McNEIL,  its Affiliates and  sublicensees  shall mark all
Licensed Products shipped or sold in accordance with applicable U.S. and foreign
patent marking laws of the country of manufacture or sale and commercial customs
of the country in question.

               2.2.4.  ALGOS covenants that during the term of this Agreement it
and its  Affiliates  will not,  and it and its  Affiliates  will not license any
third party to, sell a product  comprising  all of (a) an NMDA  Antagonist,  (b)
acetaminophen or a pharmaceutically  acceptable salt thereof, and/or ibuprofen *
* * or a mixture,  isomer or pharmaceutically  acceptable salt thereof,  and (c)
less than a recognized  effective  dose of an anesthetic  or another  analgesic.
ALGOS' and its  Affiliates'  compliance  with this covenant  shall be determined
only at the time of first  commercial  sale of ALGOS',  its  Affiliates'  or its
licensees'  products;  there will be no breach of this covenant if  subsequently
FDA approves an ingredient  for  analgesic or  anesthetic  use or if the dose of
ingredient used in the Licensed  Product is  subsequently  determined to be less
than a recognized  effective  dose.  This  covenant  shall expire as to products
comprising  acetaminophen  or  pharmaceutically  acceptable  salts  thereof,  or
products  comprising  ibuprofen * * * or a mixture,  isomer or  pharmaceutically
acceptable  salt  thereof,  upon  any  expiration  or  termination  of  McNEIL's
exclusive license to sell Licensed Products  comprising  Acetaminophen or NSAID,
respectively.

               2.2.5.  ALGOS shall notify  McNEIL if at any time ALGOS or any of
its  Affiliates  decide to either  license  or  conduct a  clinical  trial for a
product   comprising   (a)  an  NMDA   Antagonist,   (b)   acetaminophen   or  a
pharmaceutically  acceptable salt thereof and (c) aspirin. McNEIL shall have the
first right to negotiate with ALGOS or its Affiliates for rights to such product
for a period of sixty (60) days from the date of ALGOS'  notice.  If the parties
do not reach an  agreement,  ALGOS or its  Affiliate  may pursue such product or
license it to any third  party.  If ALGOS or its  Affiliates  propose to license
such product to a third party on terms less favorable to ALGOS or its Affiliates
than those last  offered by McNEIL,  ALGOS or its  Affiliates  shall  offer such
terms to McNEIL and McNEIL shall have thirty (30) days to accept such terms.

        2.3. ALGOS hereby further agrees,  at the written request of McNEIL,  to
grant direct  licenses  containing the same terms,  conditions and provisions as
this  Agreement,  except  for the  payments  set forth in  Section  3.1,  to any
Affiliate under the ALGOS Rights.  Any such licensed  Affiliate shall thereafter
report Net Sales and make running royalty payments directly to ALGOS;  provided,
however,  any such  running  royalty  payments  made  directly  to ALGOS by such
Affiliate  shall be treated as a royalty  payment made by McNEIL for purposes of
calculating  the minimum  royalty due hereunder to ALGOS under  Sections 4.5 and
4.6. Additionally, ALGOS agrees that it will accept performance hereunder of any
of McNEIL's  obligations  from any Affiliate or sublicensee of McNEIL,  provided
that McNEIL shall guaranty the performance of any such obligations.

                                      7

        2.4. McNEIL shall provide ALGOS with a copy of any sublicense  agreement
promptly upon execution  thereof.  ALGOS shall forward another copy to VCU under

obligations of Article 6.

                                    ARTICLE 3

                    MILESTONE PAYMENTS AND EQUITY INVESTMENT

        3.1.  McNEIL  shall make lump sum  payments in U.S.  Dollars to ALGOS as
follows:

                3.1.1.  by ten  (10)  days  after  the  full  execution  of this
Agreement,  an  initial  one-time  milestone  payment  of  Two  Million  Dollars
($2,000,000), which amount is intended to partially defray ALGOS' costs incurred
prior to the  Effective  Date in the  development  of the ALGOS  Rights  and the
conduct   of   clinical   trials,   including   most   recently   a   Phase   II
dextromethorphan/ibuprofen trial.

                3.1.2.  by sixty (60) days after * * * * * * * * * * * * * * * *

                3.1.3.  by sixty (60) days * * * * * * * * * * * * * * * * * * *

                3.1.4.  by sixty (60) days after * * * * * * * * * * * * * * * *

                3.1.5.  by sixty (60) days after * * * * * * * * * * * * * * * *

                3.1.6.  by sixty (60) days following * * * * * * * * * * * * * *

                3.1.7.  by sixty (60) days following * * * * * * * * * * * * * *

                3.1.8.  by sixty (60) days following * * * * * * * * * * * * * *

                3.1.9.  by sixty (60) days following * * * * * * * * * * * * * *

        For the  avoidance  of any doubt,  it is  explicitly  agreed that only a
single payment shall be made under each of Sections 3.1.1 through 3.1.9 and that
any subsequent * * * * shall not incur any further milestone payments.  Further,
any * * * * shall not incur any milestone payments set forth above. The total of
payments  due under this  Section  3.1 shall in no event  exceed * * * If one or
more milestone payments are made

                                       8

with respect to a given Licensed  Product  comprising  Acetaminophen  or a given
Licensed Product  comprising a NSAID,  such milestone  payments need not be made
again if a  subsequent  Licensed  Product  of  either  such type  achieves  such
milestone,  but any  unpaid  milestone  amount  shall  be  paid if a  subsequent
Licensed Product of either such type achieves the milestone.

        3.2.  ALGOS shall  arrange for its  underwriters  to offer McNEIL or its
designated  Affiliate the opportunity to purchase in ALGOS' initial underwritten
public  offering  (IPO) of Common Stock  pursuant to an  effective  registration
statement  under the  Securities  Act of 1933, as amended,  on the same terms as
others  purchasing  in such IPO, a number of shares of the Common Stock of ALGOS
equal to ten percent  (10%) of the number of original  issue  shares sold in the
IPO (including any over-allotments  exercised by ALGOS'  underwriters),  up to a
maximum  investment  of $6.5 million.  McNEIL  hereby  confirms its intention to
purchase such securities in ALGOS' IPO,  provided the effective date of such IPO
takes place within two (2) years of the Effective Date. However, McNEIL shall be
under no obligation to purchase any or all of such securities.

        Notwithstanding anything in this Agreement to the contrary, in the event
McNEIL fails to purchase, or make a bona fide offer to purchase, such securities
(provided the IPO takes place within such two (2) year period), ALGOS shall have
the right for a period of 90 days from the  effective  date of its  offering  to
terminate this Agreement by giving McNEIL 10 days written  notice.  In the event
ALGOS  exercises its  termination  option purchase to this Section 3.2, it shall
retain the initial payments hereunder.

        3.3. If McNEIL or its designated  Affiliate purchases all or any portion
of the securities  described in Section 3.2 above, it agrees that neither it nor
its affiliates, as defined in Rule 12b-2 of the Securities Exchange Act of 1934,
as  amended  (the  "Exchange  Act"),  will,   directly  or  indirectly,   unless
specifically  permitted to do so in writing in advance by ALGOS, sell,  transfer
or  otherwise  convey,  or agree to sell,  transfer or  otherwise  convey to any
non-Affiliate,  any interest in all or any portion of such securities during the
two year period following the effective date of the IPO without  informing,  and
offering to discuss with, the management of ALGOS regarding such action at least
seven (7) days prior to taking such action.

                                    ROYALTIES

        4.1. Commencing in the Fiscal Year in which the First Commercial Sale of
Patented Product takes place,  McNEIL shall pay to ALGOS a running royalty based
on aggregate Net Sales of Patented Products in the Territory as follows: * * * *
* * * * *

        4.2. Commencing in the Fiscal Year in which the First Commercial Sale of
Licensed Product which is not a Patented  Product takes place,  McNEIL shall pay
to ALGOS a running  royalty of * * * of Net Sales of Licensed  Product  which is
not a Patented Product sold in a country of the Territory during any time period
of Regulatory Market Exclusivity for such Licensed Product in such country.

        4.3. No running  royalties  due under this  Article  shall be payable on
sales transactions as between McNEIL and any Affiliate or sublicensee, the final
vendee sale to an  independent  third party alone being used for the purposes of
determining the running royalty payments due hereunder. Only one running royalty
payment shall be payable on the sale of each  Licensed  Product and such running
royalty will be provided in accordance with either Section 4.1 or 4.2 hereof but
not both, with the higher of such royalties to apply in the event both tests are
somehow satisfied.

        4.4. Net Sales of Licensed  Product in any country  where such  Licensed
Product is not a Patented  Product and where no period of  Regulatory  Marketing
Exclusivity  for such  Licensed  Product  is in effect  shall  incur no  running
royalties.

        4.5.  Minimum  royalties shall be due and payable by McNEIL for Patented
Products comprising Acetaminophen in accordance with the following schedule:

Fiscal Year                                        Minimum Royalty
- -----------                                        ---------------

* * * * * * * * * *Chart Intentionally Omitted* * * * * * * * * *

        For purposes of this Section 4.5,  "Fiscal Year 1" shall commence on the
first day of the first full Fiscal Year after the U.S. FDA first approves an NDA
for a Patented Product in the U.S.  comprising  Acetaminophen;  or, if the first
Licensed Product comprising  Acetaminophen for which an NDA has been approved is
not a Patented  Product in the U.S. at the time of such FDA approval,  the first
day of the first full Fiscal Year after such approved product becomes a Patented
Product in the U.S. by reason of patent issuance. Notwithstanding the foregoing,
minimum  royalties shall commence on the first day of the Fiscal Year commencing
approximately  * * * except as otherwise  provided in the  following  paragraph,
provided that (i) if McNeil has not

                                       10

<PAGE>
<PAGE>

submitted an NDA for Licensed Product comprising  Acetaminophen to the U.S. FDA,
a Valid Claim  exists in the U.S.  claiming a method or  composition  comprising
acetaminophen  and an analgesia  enhancing  amount of  dextromethorphan  for the
treatment of acute pain, or (ii) if McNEIL has  submitted  such an NDA, but such
NDA has not been  approved by the U.S.  FDA,  the  Licensed  Product  comprising
Acetaminophen  for which  McNEIL is seeking  approval  under such NDA would be a
Patented Product in the U.S., if approved on such date. If minimum  royalties do
not commence as of * * * because the Licensed Product described under (ii) above
would not be a Patented  Product in the U.S. if approved on such date, but later
a Valid Claim issues which would make such Licensed  Product a Patented  Product
in the U.S. if it were approved,  then minimum  royalties  shall commence on the
first day of the first full Fiscal Year after the date of issuance of such Valid
Claim. In all cases, minimum royalties shall be due and payable for * * * except
that they  shall  expire  early if,  and as of the date,  the last  Valid  Claim
defining such Patented  Product in the U.S. ceases to be a Valid Claim, or as of
the date the  Licensed  Product  under (ii) above for which  approval  is sought
would no longer be a Patented  Product in the U.S., if approved.  In such event,
minimum royalties shall be pro-rated for the portion of the Fiscal Year in which
such Valid  Claim  existed or the  Licensed  Product  under (ii) above for which
approval is sought would have been a Patented Product in the U.S., if approved.

        If an NDA in the U.S.  for a  Patented  Product  in the U.S.  comprising
Acetaminophen  has  not  been  approved  by the  first  day of the  Fiscal  Year
commencing  approximately * * * then McNEIL may seek a delay in the commencement
of minimum  royalties as provided in Section 4.7 if McNEIL  demonstrates that it
has designed and executed clinical trials,  compiled data,  prepared  regulatory
filings and pursued such filings with FDA in a manner consistent with its normal
business  practices  when seeking  prompt  approval for NDA products.  If McNEIL
fails to  demonstrate  such  performance,  it will be  liable  for such  minimum
royalties  but will not  otherwise  be in breach of this  Agreement by reason of
such failure.  After an NDA has been approved in the U.S. for a Patented Product
in the U.S.  comprising  Acetaminophen,  minimum  royalties  shall  commence  as
provided  in the  previous  paragraph  without  regard to any  delay  previously
experienced.

        If more than one Patented Products comprising Acetaminophen are pursued,
minimum  royalties  shall apply to the class of all such  products.  If U.S. FDA
approval for all previously  approved Patented  Products in the U.S.  comprising
Acetaminophen is suspended or revoked for reasons beyond the reasonable  control
of McNEIL, the minimum royalties hereunder shall be suspended for a like period.

        4.6.  Minimum  royalties shall be due and payable by McNEIL for Patented
Products comprising an NSAID in accordance with the following schedule:

Fiscal Year                                        Minimum Royalty
- ----------                                         ---------------

        For purposes of this Section 4.6,  "Fiscal Year 1" shall commence on the
first day of the first full Fiscal Year after the U.S. FDA first approves an NDA
for a Patented Product in the U.S.  comprising  NSAID; or, if the first Licensed
Product  comprising  NSAID for which an NDA has been  approved is not a Patented
Product in the U.S. at the time of such FDA approval, the first day of the first
full Fiscal Year after such approved  product becomes a Patented  Product in the
U.S.  by reason of  patent  issuance.  Notwithstanding  the  foregoing,  minimum
royalties  shall  commence  on  the  first  day of the  Fiscal  Year  commencing
approximately  * * * except as otherwise  provided in the  following  paragraph,
provided  that (i) if  McNeil  has not  submitted  an NDA for  Licensed  Product
comprising  NSAID to the U.S.  FDA, a Valid Claim exists in the U.S.  claiming a
method or composition  comprising an NSAID and an analgesia  enhancing amount of
dextromethorphan  for the  treatment  of  acute  pain,  or (ii)  if  McNEIL  has
submitted  such an NDA, but such NDA has not been  approved by the U.S. FDA, the
Licensed  Product  comprising  NSAID for which McNEIL is seeking  approval under
such NDA would be a Patented  Product in the U.S.,  if approved on such date. If
minimum  royalties  do not  commence  as of * * * because the  Licensed  Product
described  under (ii)  above  would not be a  Patented  Product  in the U.S.  if
approved  on such date,  but later a Valid  Claim  issues  which would make such
Licensed  Product a  Patented  Product  in the U.S.  if it were  approved,  then
minimum  royalties shall commence on the first day of the first full Fiscal Year
after the date of issuance of such Valid Claim. In all cases,  minimum royalties
shall be due and payable for * * * except that they shall  expire  early if, and
as of the date, the last Valid Claim defining such Patented  Product in the U.S.
ceases to be a Valid Claim,  or as of the date the Licensed  Product  under (ii)
above for which approval is sought would no longer be a Patented  Product in the
U.S., if approved.  In such event,  minimum royalties shall be pro-rated for the
portion of the Fiscal  Year in which such Valid  Claim  existed or the  Licensed
Product under (ii) above for which approval is sought would have been a Patented
Product in the U.S., if approved.

        If an NDA in the U.S. for a Patented  Product in the U.S.  comprising an
NSAID  has not been  approved  by the first day of the  Fiscal  Year  commencing
approximately * * * then McNEIL may seek a delay in the  commencement of minimum
royalties as provided in Section 4.7 if McNEIL demonstrates that it has designed
and executed clinical trials,  compiled data,  prepared  regulatory  filings and
pursued such filings with FDA in a manner  consistent  with its normal  business
practices  when seeking  prompt  approval for NDA  products.  If McNEIL fails to
demonstrate such  performance,  it will be liable for such minimum royalties but
will not  otherwise be in breach of this  Agreement  by reason of such  failure.
After an NDA has been  approved in the U.S.  for a Patented  Product in the U.S.
comprising  NSAID,  minimum royalties shall commence as provided in the previous
paragraph without regard to any delay previously experienced.

                                      12

<PAGE>

        If more than one Patented Products comprising NSAID are pursued, minimum
royalties  shall apply to the class of all such  products.  If U.S. FDA approval
for all previously  approved Patented  Products in the U.S.  comprising NSAID is
suspended or revoked for reasons  beyond the reasonable  control of McNEIL,  the
minimum royalties hereunder shall be suspended for a like period.

        4.7.  McNEIL shall promptly notify ALGOS if at any time it believes that
there  has  been  a   substantial   delay  for   reasons   beyond  its   control
notwithstanding  its  application  of efforts as described in Sections 4.5, 4.6,
5.3  or  5.4,   providing  a  detailed   written   explanation  of  the  events,
circumstances  and  duration  of such delay and its program for seeking to avoid
further  delay.  The parties  shall seek to agree on whether  McNEIL has in fact
exercised such efforts and, if so, how long any affected deadline and/or payment
requirement hereunder should be extended by reason of such delay. If the parties
are  unable to agree,  the  matter  may be  referred  to an  industry  expert as
provided in Section 13.1 at the request of either party.

        4.8. All running  royalties  shall be calculated and payable on a Fiscal
Quarter basis and running  royalties  shall be paid within  forty-five (45) days
following the end of such Fiscal Quarter. Each such payment shall be accompanied
by a written  report  indicating  the volume of Licensed  Products  sold in each
country,  total revenue  received and the amount of Net Sales during such Fiscal
Quarter and a calculation  of the  royalties  due. In the event that the running
royalties,  as calculated in accordance  with Sections 4.1 and 4.2, for Patented
Products comprising  Acetaminophen,  or those comprising NSAIDs, as the case may
be,  for a Fiscal  Year in which a  minimum  royalty  applies  to such  class of
Patented  Products,  are  less  than the  applicable  minimum  royalty  for such
Patented Products in such Fiscal Year, McNEIL in order to maintain its exclusive
license under this  Agreement  shall pay to ALGOS,  together with its payment of
running  royalties in  accordance  with  Sections 4.1 and 4.2 for the  reporting
period  ending  with the close of the Fiscal  Year,  the  shortfall  between the
minimum royalty and the running  royalty.  Such shortfall paid to ALGOS shall be
creditable  against  any  future  running  royalties,  but  not  future  minimum
royalties, otherwise due on Patented Products comprising Acetaminophen, or those
comprising  NSAIDs,  as the case may be, in the next  subsequent  Fiscal Year in
which running royalties shall be payable.

        4.9.  ALGOS  shall have the right,  at its own  expense,  for the period
during which a running  royalty is due to ALGOS and for three (3) full  calendar
years thereafter,  to have an independent  certified public accountant,  to whom
McNEIL has no reasonable  objection,  examine the relevant  books and records of
account of McNEIL during reasonable  business hours and no more than once during
each Fiscal Year,  to  determine  whether  appropriate  payment has been made by
McNEIL  hereunder.  The  accountant  shall  disclose  to ALGOS only  information
relating to the  accuracy of the royalty  report and the royalty  payments  made
according to this Agreement. The information received by the accountant shall be
held confidential except for information

                                      13

<PAGE>
<PAGE>

necessary  for  disclosure  to ALGOS to  establish  the  accuracy of the royalty
reports.  If such  inspection  reveals a deficiency  of greater than ten percent
(10%) in amounts due in any Fiscal Year, McNEIL shall pay the full costs of such
inspection. VCU shall have the same rights as ALGOS under this Section 4.9.

        4.10. The remittance of royalties payable on sales outside the U.S. will
be payable to ALGOS in U.S.  Dollars  according to 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  York  edition,  for the last day of the  Fiscal
Quarter for which the royalty payment is made. If the transfer or the conversion
into U.S. Dollars 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 whatever  currency is allowable and  acceptable  by ALGOS,  to the credit and
account of ALGOS or its nominees in any commercial  bank or trust company of its
choice located in that country.  Prompt notice of this deposit shall be given by
McNEIL to ALGOS.

        4.11.  Any tax  required to be withheld  on  royalties  payable to ALGOS
under the laws of any foreign  country  shall be promptly paid by McNEIL for and
on behalf of ALGOS to the  appropriate  governmental  authority and McNEIL shall
furnish  ALGOS with proof of payment of such tax together with official or other
appropriate evidence issued by the appropriate governmental authority sufficient
to enable  ALGOS to  support a claim for income tax credit in respect of any sum
so withheld.

        4.12.  Notwithstanding  any provision of this Article 4 to the contrary,
no running  royalty or minimum  royalty  shall be due for any  Licensed  Product
whose  approved and marketed  indications  are limited to the treatment of cold,
influenza,  cough and/or  dysmenorrhea,  and/or pain  associated with any of the
foregoing or mouth pain.

                                    ARTICLE 5

                            RESEARCH AND DEVELOPMENT

        5.1.  McNEIL  has or shall  initiate  within  sixty  (60) days after the
Effective  Date of this  Agreement  and shall  complete by * * * the dental pain
study for Licensed  Product  comprising  Acetaminophen  in  accordance  with the
protocol  attached as Schedule B hereof.  ALGOS shall within ten (10) days after
the  Effective  Date of this  Agreement  deposit into an escrow  account for the
benefit  of McNEIL a sum equal to the  amount  set forth in the  budget  for the
dental  pain study  attached  as  Schedule B or Five  Hundred  Thousand  Dollars
($500,000),  whichever is less.  The escrow agent shall be a U.S.  bank or trust
company selected by ALGOS, and interest earned in escrow will be for the account
of ALGOS.  The escrowed  sum shall be paid to McNEIL or its designee  within ten
(10) days after McNEIL's presentation to ALGOS of invoices,

                                       14

<PAGE>
<PAGE>

receipts  or other  documentation  evidencing  out-of-pocket  costs  incurred in
accordance  with the study set forth in Schedule B. If McNEIL  fails to initiate
and  complete  the study as set forth  above,  and subject to Section  5.7,  the
remaining  escrow  funds shall be  returned to ALGOS and the parties  agree that
ALGOS'  sole  remedy  shall be the right to  terminate  the  license  under this
Agreement for products in the Field comprising Acetaminophen under Section 10.2.

        5.2. ALGOS shall use diligent efforts to initiate within sixty (60) days
following  issuance  of the final  report  for  McNEIL's  dental  pain  study on
Licensed Product comprising Acetaminophen described in Section 5.1, and complete
* * * following  such  issuance,  an  additional  dental pain study for Licensed
Product  comprising  Acetaminophen  in  accordance  with the  protocol  synopsis
attached  as  Schedule  C  hereto.  ALGOS  shall be  responsible  for all  costs
associated with this study and shall promptly  provide McNEIL with a copy of the
final report for such study,  provided,  however,  that McNEIL shall supply drug
for use in the  study at no cost to  ALGOS.  If  ALGOS  fails  to  initiate  and
complete the study as set forth  above,  and subject to Section 5.7, the parties
agree McNEIL's sole remedy shall be the right to credit the sum of * * * against
any future milestone payments due under Section 3.1.

        5.3.  McNEIL shall initiate work on the  development  plan in accordance
with the  attached  Schedule F for  Licensed  Product  comprising  Acetaminophen
("APAP Plan") and shall have completed  Phase A and initiated  required  studies
under Phase B of the APAP Plan on or before (a) * * * or (b) * * * upon  payment
to ALGOS of the onetime sum of * * * or (c) * * * upon timely payment.  to ALGOS
of the sum paid  under (b)  above and an  additional  onetime  payment  of * * *
within thirty (30) days after * * * The payments made under (b) and (c) above to
extend the date for completing the Phase A and initiating required studies under
Phase B shall be at McNEIL's  option.  If McNEIL has not  completed  Phase A and
initiated  required studies under Phase B of the APAP Plan under (a), (b) or (c)
above, the parties agree that ALGOS' sole remedy shall be the right to terminate
the  license  under  this  Agreement  for  products  in  the  Field   comprising
Acetaminophen  under  Section  10.2.  If any  substantial  delay  occurs  in the
completion of Phase A and/or initiation of required studies under Phase B of the
APAP Plan for reasons  beyond  McNEIL's  control  notwithstanding  the fact that
McNEIL has  designed  and executed  such study in a manner  consistent  with its
normal business  practices when seeking prompt  approval for NDA products,  then
McNEIL may seek to extend such  deadlines  by  demonstrating  such  diligence in
accordance with Section 4.7.

        5.4.  McNEIL shall initiate work on the  development  plan in accordance
with the  attached  Schedule F for  Licensed  Product  comprising  a first NSAID
("NSAID Plan") and shall have completed Phase A and initiated  required  studies
under Phase B of the NSAID Plan on or before (a) * * * or (b) * * * upon payment
to ALGOS of the onetime  sum of * * * or (c) * * * upon timely  payment to ALGOS
of the sum paid

                                      15

<PAGE>
<PAGE>

under (b) above and an  additional  onetime  payment of * * * The payments  made
under  (b) and (c)  above to  extend  the date for  completing  the  Phase A and
initiating required studies under Phase B shall be at McNEIL's option. If McNEIL
has not completed  Phase A and initiated  required  studies under Phase B of the
NSAID Plan under (a),  (b) or (c) above,  the  parties  agree that  ALGOS'  sole
remedy  shall be the right to terminate  the license  under this  Agreement  for
products in the Field  comprising  NSAID under Section 10.2. If any substantial,
unexpected  delay  occurs  in the  completion  of Phase A and/or  initiation  of
required  studies  under Phase B of the NSAID Plan for reasons  beyond  McNEIL's
control  notwithstanding  the fact that McNEIL has designed  and  executed  such
study in a manner  consistent  with its normal  business  practices when seeking
prompt approval for NDA products,  then McNEIL may seek to extend such deadlines
by demonstrating such diligence in accordance with Section 4.7.

        5.5. Under Phase C of each of the  development  plans in accordance with
Schedule F, McNEIL in consultation  with ALGOS shall develop a plan and protocol
for  conducting  a first  Phase  III  Clinical  Trial in the  Field  for each of
Licensed Product  comprising  Acetaminophen  and Licensed  Product  comprising a
first  NSAID.  For the  purposes of this  Agreement  the dental pain studies set
forth in Phase A of the  development  plan of  Schedule F for  Licensed  Product
comprising  Acetaminophen or a first NSAID shall not be considered a first Phase
III Clinical  Trial for the purposes of this  Agreement.  ALGOS and McNEIL agree
that these first Phase III Clinical Trial activities shall be primarily paid for
by McNEIL and implemented primarily by McNEIL or as otherwise agreed to by ALGOS
and McNEIL and that any  activities  of ALGOS in this  regard be  controlled  by
McNEIL.

        5.6.  If McNEIL and ALGOS  have not for any reason  agreed to a plan for
carrying out the above  described  clinical work as  contemplated in Section 5.5
above by * * * then McNEIL may  unilaterally  proceed with such trials and ALGOS
shall reasonably cooperate to the extent required by McNEIL.

        5.7.  Should McNEIL or ALGOS fail to perform in accordance with Sections
5.1 or  5.2  above,  the  obligor  shall  provide  the  obligee  with a  written
justification  for such failure.  The obligee will consider such  justification,
and will consider  suggestions by the obligor party to modify the milestones and
target  dates  specified  in Sections  5.1 or 5.2.,  In the event that ALGOS and
McNEIL fail to reach  agreement on new  milestones  and target dates,  ALGOS and
McNEIL will submit to an independent  industry  expert new milestones and target

amended by the  parties or  established  by  arbitration,  the  obligee may then
exercise the right specified in Sections 5.1 or 5.2.

               5.10.2. All Intellectual Property in the Field conceived or first
reduced to practice during the term of the  Confidentiality  Agreement set forth

nominees, their successors or assigns, and shall render all assistance as McNEIL
may  require  in any Patent  Office  proceeding  or  litigation  involving  such
Intellectual Property.

               5.10.3. Any NDA or other regulatory  registration  application or

        6.1. All information disclosed by one party to the other or developed by
the  parties  pursuant  to the  terms  of this  Agreement  shall  be  maintained
confidential and used only for the purposes of this Agreement in accordance with

Affiliate,  agent,  consultant,  attorney or  financial  advisor who is under an
obligation of confidentiality and non-use at least  substantially  equivalent to
the  obligations  of this  Article 6. McNEIL  shall also be free to disclose the
existence of this Agreement and the nature of the licenses granted  hereunder to
its  Affiliates  and  prospective  sublicensees,  subject  to an  obligation  of
confidentiality and non-use. The term of maintaining confidentiality of all such
information  and the  limitations on use shall be for a period of five (5) years
after the date of  termination  of this  Agreement.  Each party shall guard such
information  as  it  normally  guards  any  of  its  confidential,   proprietary
information.  Notwithstanding the foregoing, each party shall be relieved of the
confidentiality and limited use obligations of this Agreement if:

                6.1.1.  the  information  was previously  known to the receiving
party as evidenced by the prior written records of such party;

                6.1.2. the information is or becomes generally  available to the
public through no fault of the receiving party; or

                6.1.3.  the  information is acquired in good faith in the future

        6.2.  Notwithstanding  the  above  obligations  of  confidentiality  and
non-use a party may:

                6.2.1.  disclose  information  to a  regulatory  agency  that is
necessary to obtain regulatory approval in a particular jurisdiction; or

                6.2.2.  disclose  information  to a  government  agency  if  the
disclosure is necessary to protect the health and safety of the party's  workers
or the public or as required by law; or

                6.2.3.  disclose  information  reasonably required in connection
with the  development,  manufacture,  use, sale,  external  testing or marketing
trials of products in accordance with the terms of this Agreement; or

                6.2.4.  disclose information by filing patent applications,  the
filing of which is contemplated by this Agreement,  without  violating the above
secrecy provision.

In making such disclosures, the disclosing party shall obligate the recipient to
secrecy, if possible.

        6.3.  Except  for  the  filing  of a copy  of this  Agreement  with  the
Securities & Exchange  Commission  to the extent  required by law and such other
public  announcements as may hereafter become required by law, in the reasonable
judgment  of  counsel,  due to  changes  from the  facts  and  circumstances  in
existence as of the  Effective  Date,  no party  hereunder  shall  disclose this
Agreement or make any public announcement or filing concerning this Agreement or
the subject matter hereof without the prior written consent of the other, not to
be unreasonably withheld or delayed. In the event that pursuant to the foregoing
ALGOS  shall  file a copy of this  Agreement  with  the  Securities  &  Exchange
Commission,  it shall use reasonable efforts to seek confidential  treatment for
all portions  thereof  requested by McNEIL.  Any announcement or filing shall be
made available to the other party in advance of  publication  or filing,  as the
case may be, for review and comment, not to be unreasonably delayed.

        6.4.  With respect to  information  disclosed on or after the  Effective
Date  between  McNEIL and ALGOS  under the  provisions  of this  Agreement,  the
provisions  of this  Agreement  shall  govern and  prevail.  In the event of any
conflict  between this  Agreement and the  Confidentiality  Agreement of July 5,
1995 between McNEIL and ALGOS, as amended, with respect to information disclosed
on or after the Effective  Date,  the terms of this  Agreement  shall govern and
prevail.

        6.5.  The  rights  and  obligations  of this  Article  6  shall  survive
termination of this Agreement.

                       PATENT PROSECUTION AND MAINTENANCE

        7.1.  ALGOS  agrees to  prosecute  or cause to prosecute to allowance or
final rejection in the United States the patent  applications  included in ALGOS
Patent Rights. ALGOS shall issue as a patent each such application prosecuted to
allowance. ALGOS shall pay all of its attorneys fees and other costs incurred in
the preparation,  filing and prosecution of the patent applications  included in
the ALGOS Patent Rights to allowance in the United States.

        7.2. ALGOS agrees to promptly  provide (if not already  provided) McNEIL
with copies of:

                7.2.1. All patent applications included in ALGOS Patent Rights;

                7.2.2.   All  prior  art   searches   related  to  such   patent
applications and the subject matter of this Agreement; and

                7.2.3.  All  correspondence  to and  from the  U.S.  Patent  and
Trademark   Office  and  foreign   patent   offices   relating  to  such  patent
applications.

        7.3.  McNEIL  shall have the right to consult with ALGOS  regarding  the
content of the patent  applications  included in ALGOS Patent Rights,  prior art
searches and  correspondence,  and to comment thereon.  ALGOS shall consider all
such  comments  offered  by McNEIL,  it being  agreed,  however,  that all final
decisions  respecting  conduct of the  prosecution  of said patent  applications
shall rest solely in the discretion of ALGOS,  subject to VCU's right to approve
patent filings pursuant to Section 6.1 of the VCU License.

        7.4.  ALGOS shall  promptly  notify McNEIL in the event ALGOS decides at
any time to abandon or  discontinue  prosecution  of any one or more of the U.S.
patent  applications  included in ALGOS Patent Rights. Such notification will be
given as early as possible  which in no event will be less than ninety (90) days
prior to the date on which said  application(s)  will become  abandoned.  McNEIL
shall have the option, exercisable upon written notification to ALGOS, to assume
full  responsibility for the prosecution of the affected patent  application(s),
subject to Section 6.2 of the VCU  License.  If ALGOS  abandons or  discontinues
prosecution of a U.S. patent application  included in ALGOS Patent Rights,  then
all such  affected  U.S.  patent  application(s)  shall be promptly  exclusively
licensed to McNEIL, its Affiliates and sublicensees at * * * the running royalty
rate provided for in this Agreement.

                                      20

        7.5. ALGOS shall file and prosecute patent applications covering Canada,
Japan,  the  United  Kingdom,  France,  Germany,  Italy,  Spain,  Sweden and the
Netherlands  unless  otherwise  agreed by the  parties,  and any  other  foreign
countries  which ALGOS may designate in writing  (collectively,  hereinafter the
"ALGOS List"),  and any additional  foreign countries which may be designated in
writing by McNEIL (the "McNEIL List"). McNEIL shall be permitted to consult with
ALGOS in the  selection of foreign  patent  counsel and in the  preparation  and
prosecution  of said  foreign  patent  applications.  McNEIL  agrees  to pay the
reasonable  attorney fees and costs  incurred on or after the Effective  Date by
ALGOS,  not to  exceed  a  maximum  of * * *  associated  with  the  filing  and
prosecution of foreign patent application(s) in the countries on ALGOS' List and
international  or regional patent  applications  (e.g.,  the Patent  Cooperation
Treaty or European Patent  Convention)  designating one or more countries in the
ALGOS List.  All  invoices for such  attorney  fees shall be forwarded to McNEIL
within sixty (60) days of the service being rendered. ALGOS shall have the first
right to bear the attorney fees and costs associated with patent applications in
countries  appearing on McNEIL's List, and in countries appearing on ALGOS' List
to the extent not paid by McNEIL.  If ALGOS  prosecutes  any said foreign patent
application to grant,  McNEIL and its Affiliates shall have an exclusive license
under the claims of said  granted  patent in  accordance  with the terms of this
Agreement,  including the royalties  provided herein.  In the event ALGOS elects
not to pursue any such foreign patent application,  then ALGOS shall give McNEIL
written  notice  thereof  at least  thirty  (30)  days  prior to any  applicable
deadline.  McNEIL may thereafter  continue  prosecution at McNEIL's own cost. If
McNEIL  prosecutes such  application to grant,  McNEIL and its Affiliates  shall
have an exclusive  license under the claims of said granted patent in accordance
with the terms of this Agreement,  except that they shall pay running  royalties
at * * * the rates provided herein.

        7.6. ALGOS shall pay all official taxes,  annuities and fees required to
keep in force U.S. and foreign patents included in ALGOS Patent Rights and shall
submit  evidence to McNEIL  that said  government  fees have been  timely  paid.
McNEIL shall reimburse ALGOS for such expenses as provided in Section 7.7 below.
If ALGOS elects not to make such payments in any country designated by McNEIL in
the McNEIL List for maintenance of such patents, ALGOS shall provide McNEIL with
timely notice of such election and McNEIL may assume such  maintenance.  In such
event,  McNEIL's  exclusive  license  under  the  claims of such  patents  shall
continue in accordance with the terms of this Agreement, including the royalties
provided  herein,  and McNEIL may  credit  the amount of such  payments  against
running  royalties and minimum  royalties owed on Net Sales made in such country
following the date of the ALGOS notice described above.

        7.7.  McNEIL agrees to reimburse ALGOS for all official taxes, annuities
and fees incurred on or after the Effective  Date by  ALGOS and required to keep
in force those U.S. and foreign patents included  in ALGOS Patent Rights. In the
event  McNEIL

                                      21

<PAGE>
<PAGE>

has no further interest in maintaining a patent,  McNEIL shall give ALGOS thirty
(30) days written notice thereof and ALGOS may thereafter  continue  maintenance
of said  patent at its own cost.  In such  event,  McNEIL,  its  Affiliates  and
sublicensees shall have a nonexclusive  license under the claims of said granted
patent in accordance with the terms of this  Agreement,  including the royalties
provided herein.

        7.8.  It is  understood  and  agreed  that any and all costs paid for by
McNEIL for the  preparation,  filing,  prosecution  and  maintenance  of foreign
patent  application  and patents  included in the ALGOS Patent Rights under this
Article 7 shall be * * *

        7.9.  Should a  priority  or  opposition  contest  develop in any Patent
Office  throughout the world relating to a patent or patent  application  within
the ALGOS Patent  Rights,  the parties  acknowledge  that VCU may have the first
right to control such action pursuant to Section 7.6 of the VCU license.  If VCU
does not assume control of the action,  ALGOS shall have the right,  but not the
obligation, to control the contest and bear the costs thereof. If ALGOS does not
assume control of the action,  McNEIL may control the contest and bear the costs
thereof.  If McNEIL assumes  control of the contest,  ALGOS shall provide McNEIL
with all cooperation and documents required by McNEIL to prosecute such priority
or opposition  contest  including  cooperation of any licensor or consultants of
ALGOS.  ALGOS shall have the right to participate in such contest,  or designate
its own counsel to so participate,  at ALGOS' own expense,  throughout each step
of such priority or opposition  contest.  In the event that McNEIL does not wish
to maintain a patent or patent application in any country of the Territory where
such a contest has developed then ALGOS shall be given sixty (60) days notice in
which to elect to continue  maintaining  such patent or patent  applications  at
ALGOS'  own  expense.  If ALGOS  elects  to  maintain  such a patent  or  patent
application,  such patent or patent application shall be nonexclusively licensed
to McNEIL,  its Affiliates and sublicensees in accordance with the terms of this
Agreement, including the royalties provided herein.

        7.10.  McNEIL shall notify ALGOS in writing at least thirty (30) days in
advance before McNEIL or any of its Affiliates or sublicensees brings any action
challenging  any ALGOS Patent Rights.  In such notice,  McNEIL shall describe in
detail the nature of such  action,  the  position to be advanced by McNEIL,  its
Affiliate or sublicensee  and the  commercial  reasons for bringing such action.
McNEIL will consult with ALGOS  regarding such action during such 30-day period,
taking ALGOS' views into account in good faith before making any final  decision
to bring such action.

                       COMPETING PRODUCTS AND INFRINGEMENT

        8.1.

               8.1.1.   If  ALGOS  or  McNEIL   become   aware  of   substantial
infringement  * * * * by a third  party of any issued  patent  included in ALGOS
Patent Rights,  that party shall  promptly  notify the other party in writing to
that  effect.  If,  prior to the  expiration  of * * * from said  notice,  ALGOS
obtains a discontinuance  of such  infringement or brings suit against the third
party  infringer,  then the  obligation  of McNEIL to pay  royalties  under such
Patented Product shall continue  unabated.  ALGOS shall bear all the expenses of
any suit brought by it and shall  retain all damages or other monies  awarded or
received in settlement  of such suit.  McNEIL will  cooperate  with ALGOS in any
such suit and shall have the right to consult with the ALGOS and be  represented
by its own counsel at its own expense.

               8.1.2.  If, after the  expiration  of said * * * from the date of
said notice,  ALGOS has not obtained a discontinuance of such  infringement,  or
brought suit against the third party infringer, then McNEIL may withhold up to *
* * of running  royalties  and minimum  royalties  under the patent of the ALGOS
Patent  Rights being  infringed as provided in Section  8.1.3 until such time as
either the third party infringement has ceased or suit for infringement has been
filed by ALGOS and/or VCU;  provided that McNEIL  promptly  brings suit if ALGOS
and/or VCU does not. McNEIL shall have the right after such * * * notice period,
but not the  obligation,  to bring suit  against such  infringer  and join ALGOS
and/or  VCU as a party  plaintiff,  provided  that  McNEIL  shall  bear  all the
expenses  of such  suit.  ALGOS  will  cooperate  with  McNEIL  in any  suit for
infringement  of a patent of the ALGOS Patent Rights brought by McNEIL against a
third party,  and shall have the right to consult with McNEIL and to participate
in and be  represented  by  independent  counsel in such  litigation  at its own
expense.  McNEIL  shall incur no  liability  to ALGOS as a  consequence  of such
litigation  or any  unfavorable  decision  resulting  therefrom,  including  any
decision  holding  the patent  invalid  or  unenforceable  * * * * Further,  the
minimum royalty  applicable in accordance with Section 4.5 or 4.6 for any Fiscal
Year shall be reduced by the amount of running  royalties  in such  Fiscal  Year
withheld hereunder.

               8.1.3. * * * of running  royalties  which are based solely on the
infringed  ALGOS Patent  Rights which accrue during the pendency of any suit for
infringement  brought by McNEIL  shall be held in escrow by McNEIL until a final
decision is rendered by a court of competent  jurisdiction  from which no appeal
can be or is taken.  In the event the patent of the ALGOS  Patent  Rights  under
which such  running  royalties  are payable is held to be invalid,  the escrowed
running  royalties  and  interest  shall be  retained  by McNEIL  to the  extent
necessary to offset litigation expenses. In the event

                                      23

<PAGE>
<PAGE>

the validity of such patent of the ALGOS Patent  Rights is upheld or the suit is
settled, the accrued running royalties shall be paid to ALGOS with interest, and
any damages or other monies awarded or received in settlement of such suit shall
be applied first to reimburse McNEIL's unreimbursed  litigation expenses and the
remainder  treated  as Net  Sales of  Patented  Product  in the  Fiscal  Quarter
received. Further, the minimum royalty applicable in accordance with Section 4.5
or 4.6 for any Fiscal  Year shall be reduced by the amount of running  royalties
escrowed by McNEIL during such Fiscal Year. ALGOS shall have the right to direct
the investment of escrowed royalties.

        8.2.

               8.2.1.  In the event ALGOS or McNEIL learn that McNEIL's  making,
using or selling of Licensed Product infringes, will infringe or is alleged by a
third party to infringe a third party patent by reason of the  combination of an
NMDA  Antagonist  with  Acetaminophen  or NSAID,  as the case may be,  the party
becoming aware of same shall promptly  notify the other.  ALGOS and McNEIL shall
thereafter  attempt  to agree  upon a course of action  which may  include:  (a)
modifying  of the  Licensed  Product  or its  use  and  manufacture  so as to be
non-infringing; or (b) obtaining a license or assignment from said third party.

               8.2.2. In the event ALGOS or McNEIL cannot agree on modifying the
Licensed Product pursuant to Paragraph 8.2.1, McNEIL shall in the first instance
have  the  right to  negotiate  with  said  third  party  for  such  license  or
assignment.  In  the  event  that  such  negotiation  results  in a  consummated
agreement,  then any lump sum payment  and/or  royalties  to be paid  thereunder
shall be paid by McNEIL.  * * * of any lump sum payments or royalties to be paid
by  McNEIL,  its  Affiliates  and  sublicensees  under  such  McNEIL  negotiated
agreement shall be credited against running  royalties due ALGOS hereunder,  but
only to the  extent  of  reducing  running  royalties  due ALGOS by * * * in any
Fiscal Quarter with the remainder being carried over to the next payment period.
The minimum  royalty  applicable  in  accordance  with  Section 4.5 or 4.6 for a
Fiscal Year shall be reduced by the amount credited against running royalties in
such Fiscal Year.

        8.3. As ALGOS'  exclusive  licensee to ALGOS KNOW-HOW under ALGOS Rights
hereunder,  McNEIL  shall be entitled to enforce  any ALGOS  contractual  rights
protecting  the  confidentiality   and  non-use  of  such  KNOW-HOW,   including
confidentiality and/or non-disclosure  agreements entered into between ALGOS and
any third parties, if ALGOS elects not to enforce such rights within thirty (30)
days after receiving any request for enforcement from McNEIL.

discretion of McNEIL and/or its Affiliates.

        9.3.  ALGOS hereby  acknowledges  herein that McNEIL and its  Affiliates
already sell a large  variety of products and  acknowledges  that McNEIL and its
Affiliates may now or in the future develop or acquire  pharmaceutical  products
which may serve a similar  therapeutic  function or compete with products in the
Field.  Further,  ALGOS  recognizes  that  McNEIL and its  Affiliates  have been
actively  involved in research and  development  in the medical field and in the
investigation of entries into the pharmaceutical  field for various  therapeutic
uses and that McNEIL and its Affiliates intend to continue with such activities.
These activities may result in products which would compete with products in the
Field. Should any such products be developed and/or marketed,  they would not be
subject  to any  royalties  or other  obligations  to ALGOS  hereunder  if not a
Patented  Product or Licensed  Product  having  Regulatory  Market  Exclusivity.
Moreover,  ALGOS  realizes that the products in the Field are presently in early
stages of development,  and accordingly it is uncertain  whether or not any such
product(s) will be successfully developed and marketed by McNEIL.

        9.4.  ALGOS  hereby  represents  and  acknowledges  that  McNEIL  is not
obligated under this Agreement to continue  development of or market products in
the Field and that the  payments  provided  by McNEIL to ALGOS in  Article 3 and
Article  4 and  the  termination  rights  expressly  granted  to  ALGOS  in this
Agreement are in complete satisfaction of any duty, express or implied,  imposed
upon  McNEIL to  commercially  exploit  any of the rights and  licenses  granted
hereunder,  including without  limitation,  any obligation on the part of McNEIL
and/or its Affiliates to exercise any specific level of effort in developing and
marketing  product(s) in the Field.  Conversely,  McNEIL hereby  represents  and
acknowledges  that Sections 4.5 and 4.6 require the payment of minimum royalties
to ALGOS  under  certain  circumstances,  even if  McNEIL,  its  Affiliates  and
sublicenses have no Net Sales of Licensed Products.

        9.5.  ALGOS  expressly  warrants  and  represents  that,  at the time of
execution of this Agreement, it knows of no facts that would render the Licensed
Product obsolete.  Further, ALGOS expressly warrants and represents that, at the
time of  execution  of this  Agreement,  it knows of no third  party  patents or
pending  applications  that would  materially  affect  McNEIL's  ability to sell
Licensed  Product  nor ALGOS'  ability  to obtain  patent  protection  for ALGOS
Rights.

        9.6.  Each  party  expressly  warrants  and  represents  that  it has no
agreement  nor any other  obligation  to any third  party  that would in any way
interfere,  hamper or limit its ability to carry out and fulfill its obligations
under this Agreement.

        10.5.  ALGOS or McNEIL may  terminate  this  Agreement  should the other
party commit an act of bankruptcy,  be declared  bankrupt,  voluntarily  file or
have filed against it a petition for  bankruptcy or  reorganization  unless such
petition is dismissed  within sixty (60) days of filing,  enter into a procedure
of winding up to  dissolution  or should a trustee or receiver be appointed  for
its business  assets or  operations.  All rights and licenses  granted  under or
pursuant to this  Agreement  are,  and shall  otherwise be deemed to be, for the
purposes of Section  365(n)of  Title 11, U.S. Code  ("Bankruptcy  Code") license
rights to  "intellectual  property"  as  defined  under  Section  101(60) of the
Bankruptcy  Code.  The parties  agree that McNEIL,  as a licensee of such right,
under this

                                      27

nonexclusive  license to use,  and have access to, and McNEIL  shall  provide to
ALGOS,  all data in McNEIL's  possession  generated in the studies  described in
Sections 5.1 and 5.2. McNEIL will not be required to transfer any  registrations
for Licensed Products or to grant any license rights under any McNEIL patents.

                                   ARTICLE 11

                                INDEMNIFICATION

        11.1.  McNEIL  shall  defend,  indemnify  and hold  ALGOS  and VCU,  its

resulting  from  the  inaccuracy  of any  representation  or the  breach  by the

expense of the indemnifying party) in the defense of such claims.

        11.5. An  indemnifying  party's  (including  sublicensees')  obligations

        12.1.  ALGOS shall use its best efforts not to cause the termination and

without the express written consent of McNEIL.

        12.2.  ALGOS  shall use its best  efforts  to  perform  all  duties  and
obligations  required  under the VCU License.  ALGOS shall notify  McNEIL within
five (5) days of its  receipt  of any  termination  notices  from VCU of the VCU
License and at McNEIL's  option  shall seek to avoid said  termination  or shall

withheld.  ALGOS shall promptly provide McNEIL with a copy of such  renegotiated
or modified VCU License.

avoiding  the  termination  of the VCU  license,  ALGOS agrees that should ALGOS
default  or  receive a notice  from VCU of  default  under the VCU  license  for
failure to timely pay royalties,  ALGOS shall notify McNEIL within five (5) days
of its receipt of such notice and, if ALGOS has not already  cured any  default,
McNEIL at its  option  may cure any such  default  on ALGOS'  behalf,  including
paying any  delinquencies.  McNEIL may credit any such  payments  made to VCU to
cure ALGOS'  delinquency  against future  payments due to ALGOS  hereunder.  The
minimum royalty applicable for any Fiscal Year in accordance with Section 4.5 or
4.6 shall be reduced by the amount of running  royalty paid  directly to VCU for
Net Sales made during such Fiscal Year.

                                  MISCELLANEOUS

        13.1.

               13.1.1.  Disagreements  described in Section 1.15  regarding fair
market values or Section 4.7  regarding  deadlines  and/or  extension of payment
requirements  shall be submitted to an independent  industry  expert selected by
mutual  agreement  of the parties  within sixty (60) days of a request by either
party.  If the parties are unable to agree on an  independent  industry  expert,
each shall name one such expert prior to the end of the 60-day  period and those
two experts shall mutually select a third independent industry expert within ten
(10)  additional  days. The third expert shall serve as the deciding  expert for
purposes  of this  Section  13.1.1;  the  other  two  shall be  relieved  of any
responsibilities  other than selecting the third expert. Each party shall submit
written  materials to each other and the expert within sixty (60) days after his
or her  selection.  Each  party  shall then have  fifteen  (15) days to submit a
written rebuttal to the other's  materials.  The expert shall determine the fair
market  value in  dispute,  or the  justification  for,  and  duration  of,  any
extension of deadlines and/or payment  requirements  hereunder,  based upon such
submissions.  The  expert's  determination  shall  be  dispositive  and be given
retroactive effect. Until such determination is delivered to the parties, McNEIL
shall calculate such fair market values, or the justification  for, and duration
of, any extension of deadlines  and/or payment  requirements,  in good faith and
make applicable deadlines and/or payments accordingly.

               13.1.2. The parties recognize that disputes as to certain matters
may  from  time to time  arise  during  the  term of this  Agreement.  It is the
objective of the parties to establish procedures to facilitate the resolution of
disputes  arising  under  this  Agreement  in  an  expedient  manner  by  mutual
cooperation and without resort to litigation.  To accomplish this objective, the
parties  agree to follow the  procedures  set forth in this  Section 13.1 if and
when a dispute arises under this Agreement.

        Any party may, by written notice to the other, have any dispute referred
to their respective  executive officers  designated below or their successors or
designated   corporate  officers,   for  attempted   resolution  by  good  faith
negotiations  within  fourteen  (14) days after such  notice is  received.  Said
designated executive officers are as follows:

               For McNEIL:   President

               For ALGOS:    Chief Executive Officer

               In the event the  designated  executive  officers are not able to
resolve such dispute, either party may at anytime after the 14 day period invoke
the provisions of Section 13.1.3 hereinafter.

               13.1.3.  Any  dispute,  controversy  or claim  arising  out of or
relating  to this  Agreement,  or the  parties'  decision  to  enter  into  this
Agreement,  including,  without  limitation,  disputes relating to the validity,
construction, enforceability, alleged breach, termination or performance of this
Agreement,  other than  disputes  which are  expressly  referred  to an industry
expert  under  Section  13.1.1 and  disputes  arising  out of or relating to the
validity,  enforceability  or  infringement  of any of the ALGOS Patent  Rights,
shall be settled by binding Alternative Dispute Resolution ("ADR") in the manner
described below:

                        (a) If a party  intends  to  begin an ADR to  resolve  a
dispute,  such party shall provide written notice (the "ADR Request") to counsel
for the other party  informing such other party of such intention and the issues
to be  resolved.  From the date of the ADR  Request  and until  such time as any
matter has been finally settled by ADR, the running of the time period contained
in Section 10.2 as to which party must cure a breach of this Agreement  shall be
suspended as to the subject matter of the dispute.

                        (b) Within ten (10)  business  days after the receipt of
the ADR Request,  the other party may, by written  notice to the counsel for the
party initiating ADR, add additional issues to be resolved.

               13.1.4.  The ADR shall be  conducted  pursuant  to the  J.A.M.S./
ENDISPUTE  Comprehensive  Arbitration  Rules and Procedures  attached  hereto as
Schedule I. Should J.A.M.S./ENDISPUTE or its successor organization not exist at
the time of arbitration,  the rules  referenced  herein shall be followed by the
Panel  (as  hereinafter  defined),   who  shall  also  manage  the  arbitration.
Notwithstanding  those rules,  the following  provisions  shall apply to the ADR
hereunder.

                                      31

<PAGE>
<PAGE>

                        (a) ARBITRATOR.  The arbitration shall be conducted by a
panel of three  arbitrators  ("the  Panel").  The Panel shall be selected from a
pool of retired  independent United States federal judges to be presented to the
parties by J.A.M.S./ ENDISPUTE. If the parties are unable to agree on a panel of
arbitrators  within fifteen (15) days after the pool is presented to them,  each
shall name one and those two  arbitrators  shall mutually  select the third from
the pool. Should  J.A.M.S./ENDISPUTE or its successor  organization not exist at
the time of arbitration,  the rules  referenced  herein shall be followed by the
Panel (as  hereinafter  defined),  who shall also manage the  arbitration.  Each
arbitrator shall be neutral,  disinterested,  impartial,  and independent of the
parties and others having any known interest in the outcome,  and shall abide by
the AAA/ABA Code of Ethics for Arbitrators in Commercial  Disputes.  There shall
be no ex parte  communications  with any arbitrator  either before or during the
arbitration  relating  to the  dispute or issues  involved in the dispute or the
arbitrator's views on any such issue.

                        (b)  PROCEEDINGS.  The  time  periods  set  forth in the
J.A.M.S./ENDISPUTE  rules shall be followed,  unless a party can  demonstrate to
the Panel  that the  complexity  of the  issues  or other  reasons  warrant  the
extension of one or more of the time tables.  In such case, the Panel may extend
such time tables,  but in no event shall the time tables being  extended so that
the ADR proceeding  extends more than eighteen (18) months from its beginning to
the award. In regard to such time tables,  the parties (i) acknowledge  that the
issues  that may arise in any dispute  involving  this  Agreement  may involve a
number of complex  matters and (ii) confirm their intention that each party will
have the opportunity to conduct complete  discovery with respect to all material
issues  involved in a dispute  within the framework  provided  above.  The Panel
shall not award punitive damages to either party and the parties shall be deemed
to have waived any right to such  damages.  The Panel shall,  in  rendering  its
decision,  apply the substantive law of the State of New York, without regard to
its  conflict  of  laws  provisions,  except  that  the  interpretation  of  and
enforcement  of this Section shall be governed by the Federal  Arbitration  Act.
The  Panel  shall  apply the  Federal  Rules of  Evidence  to the  hearing.  The
proceeding  shall take place in the City of New York. The fees of the Panels and
J.A.M.S./ENDISPUTE  shall be paid by the losing party which shall be  designated
by the Panel.  If the Panel is unable to designate a losing  party,  it shall so
state and the fees shall be split equally between the Parties.

                        (c) AWARD.  The Panel is  empowered  to award any remedy
allowed by law, including money damages, multiple damages,  prejudgment interest
and attorneys'  fees, and to grant final,  complete,  interim,  or interlocutory
relief, including injunctive relief but excluding punitive damages. The decision
shall be  rendered in writing,  including  a full and precise  statement  of the
factual and legal bases for such decision.

<PAGE>

                        (d)  COSTS.  Except as set forth in  Section  13.1.3(c),
above,  each party  shall bear its own legal fees.  The Panel  shall  assess its
costs,  fees and  expenses  against the party  losing the ADR unless it believes
that neither party is the clear loser,  in which case the panel shall divide its
fees, costs and expenses according to its sole discretion.

                        (e)   CONFIDENTIALITY.   The  ADR  proceeding  shall  be
confidential  and  the  Panel  shall  issue  appropriate  protective  orders  to
safeguard each party's confidential  information.  Except as required by law, no
party shall make (or  instruct the Panel to make) any public  announcement  with
respect to the  proceedings  or  decision  of the Panel  without  prior  written
consent of each other party. The existence of any dispute  submitted to ADR, and
the award,  shall be kept in confidence by the parties and the Panel,  except as
required  in  connection  with the  enforcement  of such  award or as  otherwise
required by applicable law.

               13.1.5.  Any duty to arbitrate  under this Agreement shall remain
in effect and enforceable after termination of the contract for any reason.

               13.1.6.  For the  purposes  of this  Section  13.1,  the  parties
acknowledge their diversity (ALGOS having its principal place of business in New
Jersey and McNEIL having its principal  place of business in  Pennsylvania)  and
agree to accept the  jurisdiction of the Federal District Court in New York, New
York for the purposes of enforcing  awards entered  pursuant to this Section and
for enforcing the agreements reflected in this Section.

               13.1.7.  Any dispute  arising out of or relating to the validity,
enforceability  or  infringement  of any of the  ALGOS  Patent  Rights  shall be
subject to resolution in a court having appropriate  jurisdiction in the country
or territory where the patent is issued.  Each of ALGOS and McNEIL hereby waives
its right to trial by jury to resolve any such claim or controversy.

        13.2.  Any delays in or  failures of  performance  by a party under this
Agreement  shall  not be  considered  a breach of this  Agreement  if and to the
extent  caused  by  occurrences  beyond  the  reasonable  control  of the  party
affected,  including but not limited to: acts of God; acts,  regulations or laws
of any government;  strikes or other concerted acts of workers;  fires;  floods;
explosions;  riots; wars; rebellions; and sabotage; and any time for performance
hereunder  shall  be  extended  by the  actual  time  of  delay  caused  by such
occurrence.

        13.3.  This  Agreement,  or any of the  rights and  obligations  created
herein,  shall not be assigned or  transferred,  in whole or in part,  by either
party hereto  without the prior  written  consent of the other party;  provided,
however,  that either party shall have the right to assign this Agreement to any
Affiliate or to the successor of all or

                                      33

<PAGE>
<PAGE>

substantially  all of its business to which this Agreement  relates without such
prior written  consent.  Any attempted  assignment or transfer of such rights or
obligations without such consent, except as provided herein, shall be void.

        13.4.  The  waiver  by a  party,  whether  express  or  implied,  of any
provisions of this Agreement,  or of any breach or default of a party, shall not
be construed to be a continuing  waiver of such provision,  or of any succeeding
breach or default or of a waiver of any other provisions of this Agreement.

        13.5.  All  matters   affecting  the   interpretation,   validity,   and
performance of this Agreement  shall be governed by the laws of the State of New
York, U.S.A., without regard to its choice or conflict of law principles.

        13.6. Any provision  hereof which is prohibited or  unenforceable in any
jurisdiction  shall, as to such jurisdiction,  be ineffective only to the extent
of such  prohibition  or  unenforceability  without  invalidating  the remaining
provisions  hereof or affecting the validity or enforceability of such provision
in any other jurisdiction.  The parties shall replace such ineffective provision
for such jurisdiction with a valid and enforceable  provision which most closely
approaches the idea, intent,  and purpose of this Agreement,  and in particular,
the provision to be replaced.

        13.7.  ALGOS and McNEIL  are  independent  contractors  and shall not be
deemed to be partners,  joint ventures or each other's agents, and neither shall
have the  right to act on  behalf of the  other  except  as  expressly  provided
hereunder or otherwise expressly agreed to in writing.

        13.8.  McNEIL shall have the right to promote and sell Licensed  Product
under  trademarks  selected by McNEIL,  which trademarks shall be and remain the
property of McNEIL.  Nothing herein shall be deemed to give ALGOS, either during
the term of this  Agreement or  thereafter,  any right to McNEIL  trademarks  or
their use.

        13.9.  It is the  mutual  desire  and  intent of the  parties to provide
certainty as to their future rights and remedies  against each other by defining
the extent of their mutual  undertakings as provided herein. The parties have in
this  Agreement   incorporated  all  representations,   warranties,   covenants,
commitments and  understandings  on which they have relied in entering into this
Agreement  and,  except  as  provided  for  herein,  neither  party has made any
covenant  or  other  commitment  to the  other  concerning  its  future  action.
Accordingly,  this Agreement and the schedules  attached  hereto (i) constitutes
the entire agreement and  understanding  between the parties with respect to the
matters   contained  herein,   and  there  are  no  promises,   representations,
conditions,  provisions or terms  related  thereto other than those set forth in
this Agreement, and (ii) supersedes all previous understandings,  agreements and
representations  between the  parties,  written or oral  relating to the subject
matter hereof. The parties hereto may from time to time

1.   SCOPE OF RULES
     The J A M S/ENDISPUTE
     
     Comprehensive  Arbitration  Rules and Procedures  ("Rules")  govern binding
Arbitrations  of  disputes  or  claims  that  are  administered  by  Jo Ao Mo S/
ENDISPUTE and in which any disputed claim or counterclaim exceeds $250,000,  not
including interest.

2.   PARTY-AGREED
     PROCEDURES

     The  Parties  may agree on any  procedures  not  specified  herein that are
consistent  with the  applicable  law.  The  Parties  will  promptly  notify the
J A M S/ENDISPUTE  Case  Administrator of any  Party-agreed  procedures and will
confirm  these  procedures  in  writing.  The  Party-agreed  procedures  will be
enforceable as if contained in these Rules. These Rules will control any matters
not changed by the Party-agreed procedures.

3.   AMENDMENT OF RULES

     J A M S/ENDISPUTE may amend these Rules. The Rules in effect on the date of
the  commencement  of an  Arbitration  (as defined in Rule 5) will apply to that
Arbitration, unless the Parties have specified that another version of the Rules
applies.

4.   CONFLICT WITH LAW

     If any of these Rules,  or a  modification  of these Rules agreed on by the
Parties,  is  discovered  to  be in  conflict  with  a  mandatory  provision  of
applicable  law, the  provision  of law will  govern,  and no other Rule will be
affected.

5.   COMMENCING AN
     ARBITRATION

     A J A M S/ENDISPUTE Comprehensive Arbitration is commenced by either:

     (A) the submission to  J A M S/ENDISPUTE by all Parties of a fully executed
J A M S/ENDISPUTE Arbitration Agreement;

     (B)  the  submission  to   J A M S/ENDISPUTE  of   a   pre-dispute  written
contractual  provision  requiring the Parties to arbitrate the dispute or claim,
along with either  written  evidence of the intent of all Parties to comply with
the  requirement  or a written  demand by one  Party  that the other  Party(ies)
comply with the requirement; or

     (C) the oral  agreement  of all Parties to  participate  in an  Arbitration
conducted pursuant to these Rules.

     The  Arbitration  process is considered  commenced  when  J A M S/ENDISPUTE
confirms  in  writing  the  receipt  of the  documents  described  above and the
agreement of all Parties to  participate in the  Arbitration  and to be bound by
its  results.  The  date  of  commencement  of the  Arbitration  is the  date of
J A M S/ENDISPUTE's confirmation letter.

     In the event of an oral agreement to participate in an Arbitration, even if
the   Arbitration  is  commenced  with  the  issuance  of  a   J A M S/ENDISPUTE
confirmation  letter,  the  Arbitration  Hearing  will not take place  until all
Parties have executed a J A M S/ENDISPUTE Arbitration Agreement.

     If a  Party  that  is a  signatory  to a  pre-dispute  written  contractual
provision  fails to  respond to a demand  for  Arbitration  or fails to agree to
participate  in the  Arbitration  process,  J A M S/  ENDISPUTE  will confirm in
writing the  failure to respond or  participate  and,  pursuant to Rule 20, will
schedule,  and provide appropriate notice of, a Hearing or other opportunity for
the Party demanding the Arbitration to demonstrate its entitlement to relief.

6.   PRELIMINARY AND
     OTHER ADMINISTRATIVE
     CONFERENCES OPTIONAL
     APPEAL PROCEDURE
                                      I-2

<PAGE>
<PAGE>


     (A) The Case Administrator(1) will conduct a  Preliminary  Conference  with
the Parties, by telephone, within seven  (7)  calendar  days  after  the date of
commencement  of  the  Arbitration.  The  Case  Administrator  will  answer  any
questions  regarding these rules and will discuss procedural matters such as the
pleading  or notice of claim  sequence,  Arbitrator  selection,  a schedule  for
discovery,  if any, and the location and scheduling of the Arbitration  Hearing,
including  the  expectations  of  the  Parties  as to the  length  of  time  the
Arbitration Hearing is likely to require.

     (B) At any subsequent  time,  the Case  Administrator  may convene,  or the
Parties  may  request,  additional  conferences  to  discuss  administrative  or
procedural matters.

(C) At either the  Preliminary  Conference  or at  subsequent  conferences,  the
Parties a nd the Case  Administrator may identify any substantive,  evidentiary,
procedural  or  discovery-related  disputes  that  should  be  considered  in  a
conference  with the  Arbitrator(s).  In  addition,  at either  the  Preliminary
Conference or at subsequent  conferences,  the Case  Administrator may offer the
assistance of J A M S/ENDISPUTE  in exploring  settlement  through  mediation or
other non-binding alternative dispute resolution processes.

     (D) During the Preliminary Conference,  the Case Administrator will ask the
Parties if they agree to the Optional Appeal Procedure set forth in Rule 23. All
Parties must agree in writing for the Optional Appeal Procedure to be effective.
Once a Party has agreed to the Optional Appeal Procedure, it cannot unilaterally
withdraw  from  it,  unless  it  withdraws,   pursuant  to  Rule  12,  from  the
Arbitration. The Parties may subsequently agree to the Optional Appeal Procedure
at any time prior to the Arbitration Award becoming final pursuant to Rule 22.

7.   NUMBER OF
     ARBITRATORS AND
     APPOINTMENT OF
     CHAIRPERSON

     (A) J A M S/ENDISPUTE  Comprehensive  Arbitrations will be conducted by one
neutral Arbitrator, unless all Parties agree otherwise.

     (B) In cases involving more than one Arbitrator, the Parties will agree on,
or in the  absence  of  agreement  the  Case  Administrator  will  designate,  a
Chairperson of the Arbitration Panel. The Chairperson will have the authority to
act as a single  Arbitrator  for the  purposes  of ruling on all  discovery  and
procedural  matters,   including  pleading  issues,  but  not  with  respect  to
dispositive,   jurisdictional   and  sanction  issues.  All  references  to  the
Arbitrator in these Rules will apply to the Chairperson of the Arbitration Panel
where appropriate.

8.   SERVICE

     Service  under  these  Rules  will  be made by  providing  one  copy of the
document  to each  Party and two  copies to the Case  Administrator.  If a three
member  Arbitrator  panel is used, four copies of all documents will be provided
to the Case Administrator. Service may be made by hand-delivery, Federal Express
or other similar services,  facsimile  transmission or by U.S. mail.  Service is
considered effective upon the date of receipt of the document.

9.   NOTICE OF CLAIMS

     (A) If a matter has been submitted for  a  J A M S/ENDISPUTE  Comprehensive
Arbitration  after a litigation has been  commenced in court  regarding the same
claim or dispute,  the pleadings in the court case,  including the Complaint and
Answer (with affirmative  defenses and counter or cross claims),  will be served
on  J A M S/ENDISPUTE  within fourteen (14) days of the date of commencement and
will be considered part of the record of the Arbitration.

     It will be  assumed  that  the  existence  of  such  pleadings  constitutes
appropriate  notice to the Parties of the claims,  counter or cross claims,  and
affirmative   defenses  that  each  has.  If  necessary,   such  notice  may  be
supplemented pursuant to Rule 9 (B).

     (B) If a matter has been submitted prior to or in lieu of the filing of the
case in court or prior to the filing of an Answer,  the  Parties  must give each
other  notice of all claims,  counter or cross claims and  affirmative  defenses
(including jurisdictional challenges) that each has. Such notice may be provided
by the service upon the other Party(ies) and upon  J A M S/ENDISPUTE,  of either
an  appropriate  pleading  (in the form of either a  Complaint  or  Answer) or a
letter. The letter should include a short statement of the factual basis for the
claims, counter or cross claims and affirmative defenses (including the basis of
any jurisdictional challenge).

     Notice of claims,  counter or cross claims and affirmative  defenses may be
exchanged  simultaneously,  in which  case they  should  be  served on  J A M S/
ENDISPUTE  within fourteen (14) calendar days of the date of commencement of the
Arbitration,  or by such other date as the  Parties  may agree.  The  responding
Party(ies) may, however,  in its sole discretion,  wait to receive the notice of
claim  before  serving  its  response,  including  counter  or cross  claims  of
affirmative  defenses.  In this case, the response,  including  counter or cross
claims and affirmative  defenses,  should be served on the other  Party(ies) and
upon  J A M S/ENDISPUTE  within  fourteen  (14) calendar days of having received
the notice of claim.  Any Party that is a recipient  of a counter or cross claim
may reply to such counter or cross  claim,  including  asserting  jurisdictional
challenges. In this case, the reply should be served on the other Party(ies) and
J A M S/ENDISPUTE  within  fourteen  (14)  calendar days of having  received the
notice of counter or cross claim.

     No claim,  counter or cross claim or affirmative defense will be considered
by the Arbitrator in the absence of prior notice to the other Party(ies), unless
all Parties agree that such  consideration  is appropriate  notwithstanding  the
lack of prior notice.

     If any Party  fails to respond to a claim or fails to reply to a counter or
cross  claim,  that Party will be deemed to have denied the  claims,  counter or
cross claims made against it but to have waived the right to assert other claims
or challenges to jurisdiction.
                                      I-3


<PAGE>
<PAGE>

     (C) Amendments  or  additions to claims and counter or cross claims may be
made only on  application to the  Arbitrator,  who may allow such changes upon a
showing of good cause and no prejudice to the opposing Party(ies).

10.  INTERPRETATION OF
     RULES AND 
     JURISDICTIONAL 
     CHALLENGES

     (A) Once  appointed,  the  Arbitrator  will  resolve  disputes  about  the
interpretation and applicability of these Rules,  including disputes relating to
the duties of the Arbitrator and the conduct of the Arbitration Hearing,  except
that in cases  involving  more than one  Arbitrator  all such issues that may be
dispositive  with respect to a claim will be ruled on by the Arbitration  Panel.
The resolution of the issue by the Arbitrator or Panel is final.

     Jurisdictional disputes,  including disputes over the existence,  validity,
interpretation or scope of the agreement under which Arbitration is sought, will
be submitted to and ruled on by the Arbitrator(s).

     (B) Disputes  arising  before the  appointment  of the  Arbitrator  will be
resolved  by the  Case  Administrator,  but  only  those  disputes  relating  to
jurisdiction and the conduct of the Hearing are subject to subsequent  review by
the Arbitrator.

11.  REPRESENTATION

     The Parties may be represented by counsel.  Each Party will promptly notify
the Case  Administrator  and the  other  Party(ies)  of the  name,  address  and
telephone  and fax numbers of its  counsel.  The attorney for a Party may act on
the Party's behalf in complying with these Rules.

12.  WITHDRAWAL FROM
     ARBITRATION

     No Party may terminate or withdraw from an  Arbitration  after it commences
(as  defined  in Rule 5)  except,  by written  agreement  of all  Parties to the
Arbitration.

13.  EX PARTE
     COMMUNICATIONS

     No  Party  will  have  any ex parte  communication  with the  Arbitrator(s)
regarding  any  issue  related  to  the  Arbitration.  Any  necessary  ex  parte
communication  with  J A M S/ENDISPUTE,  whether before or after the Arbitration
Hearing, will be conducted through the Case Administrator.

14.  ARBITRATOR SELECTION
     AND REPLACEMENT

     (A) Unless the Arbitrator(s)  has been previously  selected by agreement of
the Parties, the Case Administrator at the Preliminary Conference will recommend
appropriate    Arbitrator    candidates   who   have   been    pre-screened   by
J A M S/ENDISPUTE for potential conflicts of interest.  Any disclosures that are
mandated by applicable law regarding the Arbitrator  candidates  will be made at
this time. The Case Administrator will attempt during the Preliminary Conference
to reach agreement among the Parties  regarding the selection of the Arbitrator.
Any  disclosures  that are mandated by applicable  law regarding the  Arbitrator
Candidates will be made at this time.

     (B) If the Parties do not agree on an Arbitrator  within seven (7) calendar
days of the Preliminary Conference, the Case Administrator will send the Parties
a list of at least five (5) Arbitrator  candidates who have been pre-screened by
J A M S/ENDISPUTE for potential conflicts of interest.  Any disclosures that are
mandated by applicable law regarding the Arbitrator  candidates  will be made at
this time,  and  J A M S/ENDISPUTE  will also  provide  each  Party with a brief
description of the background and experience of each Arbitrator candidate.

     Any Party may,  within  seven (7)  calendar  days of receipt of the list of
names,  challenge an Arbitrator  candidate for cause and the Case  Administrator
will promptly  rule on such  challenges.  If a challenge for cause is upheld,  a
replacement name will be sent to the Party(ies), along with required disclosures
and background information about said candidate.

     Within seven (7)  calendar  days of the receipt by the Parties of the final
list of names,  each Party may strike two (2) names, and will rank the remaining
Arbitrator candidates in order of preference. The remaining Arbitrator candidate
with the highest composite ranking will become the Arbitrator.

     If this  process  does  not  yield an  Arbitrator,  J A M S/ENDISPUTE  will
designate the Arbitrator.

     (C) If a  Party  fails  to  respond  in a  timely  manner  to the  list  of
Arbitrator  candidates,  the Case  Administrator  will deem  that  Party to have
accepted all of the Arbitrator candidates.

     (D) In cases  involving more than two Parties or the selection of more than
one Arbitrator,  the Case  Administrator's list will include a sufficient number
of candidates to yield the specified number of Arbitrators,  while allowing each
Party up to two (2) strikes.

     (E) Entities whose  interests are not adverse with respect to the issues in
dispute  will be  treated  as a single  Party  for  purposes  of the  Arbitrator
selection  process.  J A M S/ENDISPUTE  will  determine  whether  the  interests
between entities are adverse for purposed of Arbitrator  selection,  considering
such factors as whether the entities are  represented  by the same  attorney and
whether  the  entities  are  presenting  joint  or  separate  positions  at  the
Arbitration.

     (F) If for any reason the  Arbitrator  who is selected is unable to fulfill
the  Arbitrator's  duties,  a successor  Arbitrator will be chosen in accordance
with this Rule. If a member of a panel of Arbitrators  becomes unable to fulfill
his or her duties after the beginning of a Hearing but before the issuance of an
Award, a new Arbitrator  will be chosen in accordance  with this Rule unless the
Parties  agree  to  proceed  with  the  remaining  two  Arbitrators.   The  Case
Administrator  will make the final  determination as to whether an Arbitrator is
unable to fulfill his or her duties.

     (G) All  Arbitrators  will execute an oath of office before being called on
to make any  determinations  in the

                                      I-4

Arbitration  proceeding and, in any event, before the taking of evidence in the
the Arbitration Hearing.

15.  EXCHANGE OF
     INFORMATION

     (A) The Parties will cooperate in good faith in the  voluntary,  prompt and
informal exchange of all non-privileged documents and other information relevant
to the dispute or claim.

     (B) The  Parties  will  exchange  copies  of all  non-privileged  documents
relevant to the dispute or a claim,  including  copies of all documents in their
possession or control on which they rely in support of their  positions or which
they intend to introduce  as exhibits at the  Arbitration  Hearing.  The Parties
will  serve  the  documents  within  twenty-one  (21)  calendar  days  after all
pleadings or notice of claims have been received, unless otherwise agreed.

     (C) The Parties will exchange the names of all  individuals  with knowledge
of the  dispute  or a  claim,  including  all  individuals  who they may call as
witnesses at the Arbitration  Hearing.  The Parties will serve the names of such
witnesses within  twenty-one (21) calendar days after all pleadings or notice of
claims have been received, unless otherwise agreed.

     (D) The Parties  will  exchange  the names of all experts who may be called
upon to testify or whose report may be  introduced at the  Arbitration  Hearing.
The Parties will serve the names of such experts within twenty-one (21) calendar
days  after  all  pleadings  or notice of  claims  have  been  received,  unless
otherwise agreed.

     (E) At any time after all pleadings or notice of claims have been received,
but no later than fourteen (14)  calendar days before the  Arbitration  Hearing,
each Party may take on  deposition  of an  opposing  Party or of one  individual
under the control of the  opposing  Party.  The Parties will attempt to agree on
the time,  location  and duration of the  deposition,  and if the Parties do not
agree these issues will be determined by the  Arbitrator.  Any Party may conduct
depositions  of its own  witnesses  which may be  introduced  as evidence at the
Arbitration Hearing if the other Party(ies) was given fair opportunity to attend
the deposition and cross-examine the witness.

     (F) Upon the request of any Party, the Arbitrator will conduct a conference
for the purpose of  determining  whether any  additional  information  should be
exchanged.  Parties  may  request  additional  depositions.  If  the  Arbitrator
determines  that the  requesting  Party has a reasonable  need for the requested
information,  and that the  request is not  overly  burdensome  on the  opposing
Party(ies),  the Arbitrator may order the additional  information exchange.  The
producing  Party(ies)  will promptly comply with any directive of the Arbitrator
by the date specified by the Arbitrator  which, in no event,  will be later than
fourteen (14) calendar days before the Arbitration Hearing.

     (G) As they become aware of new documents or information, including experts
who may be  called  upon to  testify,  all  Parties  remain  under a  continuing
obligation to provide relevant,  non-privileged  documents,  to supplement their
identification of witnesses and experts, and to honor any informal agreements or
understandings  between the Parties  regarding  documents or  information  to be
exchanged.  Documents which have not been previously exchanged, or witnesses and
experts not previously  identified,  will not be considered by the Arbitrator(s)
at the Hearing, unless agreed by the Parties.

     (H) The  Parties  will  promptly  notify  the  Case  Administrator  when an
unresolved  dispute exists regarding  discovery issues.  The Case  Administrator
will attempt to facilitate an informal  resolution of the dispute by the Parties
themselves.  If the dispute is not informally  resolved,  the Case Administrator
will arrange a conference with the Arbitrator, either by telephone or in person,
and the Arbitrator will decide the dispute.

16.  SUMMARY DISPOSITION
     OF A CLAIM OR ISSUE
   
     (A) Upon  agreement  of all Parties  interested  in a  particular  claim or
substantive issue, the Arbitrator(s) may hear and determine a Motion for Summary
Disposition of that claim or issue.

     (B) The Case  Administrator  will obtain the  agreement of the Parties on a
briefing  schedule and record for the Motion.  If no  agreement is reached,  the
Arbitrator(s)  will  set the  briefing  schedule  and  contents  of the  record.
Ordinarily,  only opening  briefs (of no more than 20  double-spaced  pages) and
response  briefs (of no more than 10  double-spaced  pages) will be allowed in a
sequence  to  be  determined.  The  briefs  may  be in  the  form  of a  letter.
Ordinarily,  oral  argument  will not be  allowed,  unless  all  Parties  or the
Arbitrator(s) so request.

     (C) The  Arbitrator(s)  will  apply  the  same  burdens  as a court  in the
jurisdiction   would  apply  under  similar   circumstances.   With  respect  to
substantive  issues,  the Arbitrator(s) will apply the same standard in deciding
the Motion as would be applicable to the Arbitration Award.

17.  SCHEDULING AND
     LOCATION OF
     HEARING

     Unless  previously  agreed  to  by  the  Parties,  the  Arbitrator,   after
consulting with the Parties,  will determine the location,  date and time of the
Arbitration  Hearing. In determining the location of the Hearing, the Arbitrator
will take into  account  such  factors as the  convenience  of the  Parties  and
witnesses as well as the  relative  resources  of the  Parties.  Absent  unusual
circumstances,  the  Arbitration  Hearing will begin within ninety (90) calendar
days of the commencement of the Arbitration. The Arbitrator and the Parties will
attempt to schedule consecutive Hearing days if more than one day is necessary.

18.      PRE-HEARING
         SUBMISSIONS

     (A) The  Arbitrator  may require a pre-Hearing  conference for the purposes
both of narrowing the focus of the  Arbitration  Hearing by stipulations of fact
or joint  statements of issues to be determined and of resolving any outstanding
issues relating to the conduct of the Hearing. The pre-Hearing conference may be
conducted by telephone.

                                      I-5

<PAGE>
<PAGE>

     (B) By at least seven (7) calendar days before the Arbitration Hearing, the
Parties will serve upon each other a list of the witnesses  they intend to call,
including  any  experts,  along  with a  short  description  of the  anticipated
testimony of the witness and an estimate of the length of the  witness's  direct
testimony.  In  addition,  by at  least  seven  (7)  calendar  days  before  the
Arbitration  Hearing,  the  Parties  will serve  upon each  other  copies of all
exhibits intended to be used at the Hearing.

     The list of  witnesses  and the  copies of all  exhibits  that the  parties
intend to use at the Hearing  should also be served upon  J A M S/ENDISPUTE  for
transmission  to the  Arbitrator(s).  The Parties should  pre-mark  exhibits and
should attempt themselves to resolve any disputes regarding the admissibility of
exhibits prior to the Hearing.

     (C) The  Arbitrator(s)  may require that each Party submit concise  written
statements  of position,  including  summaries of the facts and evidence a Party
intends  to  present,  discussion  of the  applicable  law and the basis for the
requested Award or denial of relief sought. The statements,  which may be in the
form of a letter,  should not exceed twenty (20)  double-spaced  pages in length
and  should be  submitted  to  J A M S/ENDISPUTE,  and  served  upon  the  other
Party(ies),  by at least  seven (7)  calendar  days  before  the  Hearing  date.
Rebuttal statements or other pre-Hearing written submissions may be permitted or
required at the discretion of the Arbitrator(s).

19.      SECURING WITNESSES
         FOR THE ARBITRATION
         HEARING

     At the request of another  Party,  all other  Parties  will produce for the
Arbitration  Hearing all  witnesses in their  employ or under their  control and
without need of subpoena.  The Arbitrator may issue subpoenas for the attendance
of  witnesses  or the  production  of  documents.  In the  event  a  Party  or a
subpoenaed person objects to the production of a witness or other evidence,  the
Party may file an objection with the  Arbitrator,  who will promptly rule on the
objection,  weighing both the burden on the producing  Party and the need of the
proponent for the witness.

20.  THE ARBITRATION
     HEARING

     (A) The Arbitrator(s)  will ordinarily  conduct the Arbitration  Hearing in
the manner set forth in these Rules. The Arbitrator(s) may vary these procedures
if the Arbitrator(s) determines that it is reasonable and appropriate to do so.

     (B) The  Arbitrator(s)  will  determine  the  order of  proof,  which  will
generally be similar to that of a court trial.

     (C) The  Arbitrators(s)  will require  witnesses  to testify  under oath if
requested by any Party.

     (D) The Arbitrator(s)  will consider evidence that he or she finds relevant
and  material  to the  dispute,  giving the  evidence  such  weight as he or she
determines is appropriate. The Arbitrator(s) may be guided in that determination
by the Federal Rules of Evidence or by any other  applicable  judicial  rules of
evidence;  however, strict conformity to such rules of evidence is not required,
except that the Arbitrator(s) will apply the Federal Rules of Civil Procedures.

     (E) The  Arbitrator(s)  may  receive  and  consider  witnesses'  deposition
testimony  recorded by transcript or videotape,  provided that the other Parties
have had the opportunity to attend and cross- examine.  The Arbitrator(s) may in
his or her discretion  consider witness affidavits or other recorded  testimony,
but will  give  that  evidence  only  such  weight  as the  Arbitrator(s)  deems
appropriate.

     (F) The Parties  will not offer as  evidence,  and the  Arbitrator(s)  will
neither  admit into the  record nor  consider,  prior  settlement  offers by the
Parties or statements or  recommendations  made by a mediator or other person in
connection with efforts to resolve the dispute being arbitrated.

     (G) When the  Arbitrators(s)  determines  that all  relevant  and  material
evidence and arguments  have been  presented,  the  Arbitrator  will declare the
Hearing closed.  The  Arbitrator(s) may defer the closing of the Hearing until a
date agreed upon by the Arbitrator(s) and the Parties,  to permit the Parties to
submit post-Hearing briefs, which may be in the form of a letter, and/or to make
closing  arguments.  If  post-Hearing  briefs  are to be  submitted,  or closing
arguments are to be made,  the Hearing will be deemed closed upon receipt by the
Arbitrator(s) of such briefs or the making of such closing arguments.

     (H) At any time before the Award is rendered, the Arbitrator(s) may, on his
or her own initiative or on application of a Party for good cause shown, re-open
the  Hearing.  If the  Hearing is  re-opened  and the  re-opening  prevents  the
rendering of the Award within the time limits specified by these Rules, the time
limits will be extended for an appropriate period of time.

     (I) The  Arbitrator(s)  may  proceed  with the  Hearing in the absence of a
Party who,  after having  executed the  Arbitration  Agreement  and after having
receiving  reasonable notice of the Hearing,  fails to attend. The Arbitrator(s)
may not  render an Award  solely on the basis of the  default  or absence of the
Party, but will require any Party(ies) who is present to submit such evidence as
the   Arbitrator(s)   may   require   for  the   rendering   of  an  Award.   If
J A M S/ENDISPUTE  reasonably believes that a Party will not attend the Hearing,
the Arbitrator may receive the evidence necessary to render an Award either by a
telephone conference or by affidavit.

     (J) Any Party may request  that a  stenographic  or other record be made of
the  Hearing,  provided  that  the  requesting  Party  bear  the  cost  of  such
stenographic  record and that the  original of the record by  maintained  by the
reporting service so that the other Party(ies) has equal access to it.

     If a  stenographic  or other record is made of the Hearing,  the requesting
Party(ies)  will provide a copy to the  Arbitrator.  If the Parties agree to the
Optional  Appeal  Procedure  as set forth in Rule 23,  they will  ensure  that a

                                      I-6


<PAGE>
<PAGE>

stenographic or other record is made of the Hearing and will share the cost.

21.  WAIVER OF HEARING

     The Parties  may agree to waive the oral  Hearing and submit the dispute to
the Arbitrator(s)  for an Award based on written  submissions and other evidence
upon which the Parties agree.

22.  THE AWARD

     (A) Absent  good cause for an  extension,  the  Arbitrator  will render the
award  within  thirty  (30)  calendar  days after the date of the closing of the
Hearing  or, if an  Arbitration  Hearing  has been  waived,  within  thirty (30)
calendar  days  after the date that the  Arbitrator(s)  received  all  materials
specified by the Parties.

     (B) Where a panel of  Arbitrators  has heard the dispute,  the decision and
Award of a majority of the panel will constitute the Arbitration  Award and will
be binding on the Parties.

     (C) Unless the Parties  specify a different  standard  in  determining  the
Award  the  Arbitrator(s)  will be  guided by  principles  of law and  equity as
applied to the facts found at the  Arbitration  hearing,  including  those facts
relating to custom and agreement between the Parties.

     (D) The  Arbitrator(s)  is  authorized  to Award any remedy  allowed by the
applicable law,  including  multiple damages,  pre or post judgment interest and
attorneys'  fees and  expenses  and to  grant  final  or  interlocutory  relief,
including injunctive relief,  unless the Parties have agreed to a narrower scope
of permissible relief.  Notwithstanding  this authority,  the Arbitrator may not
Award  punitive  damages  unless  previously  agreed  by the  Parties  or unless
punitive damages are required by law to be an available remedy in such cases. In
the Award, the Arbitrator may also assess Arbitration fees and expenses in favor
of either Party if provided by agreement of the Parties, or in favor of J A M S/
ENDISPUTE in the event that the  Arbitrator  finds that fees or expenses are due
J A M S/ENDISPUTE.

     (E)  The  Award  will  consist  of  a  written   statement  signed  by  the
Arbitrator(s)  regarding the  disposition of each claim and the relief,  if any,
awarded as to each claim. Unless all Parties agree otherwise,  the Arbitrator(s)
will also provide a concise written  statement of the reasons for the Award, but
this  statement  will not  become  part of the  Award nor be  admissible  in any
judicial proceeding to enforce or vacate the Award.

     (F)  J A M S/ENDISPUTE  will  issue  the  Award by  serving  copies  on the
Parties.

     (G) Within seven (7) calendar days after  service of the Award,  any Party,
with written  notice to all other Parties,  may serve upon the other  Party(ies)
and   J A M S/ENDISPUTE  a  request  that   the   Arbitrator(s)    correct   any
computational,  typographical or similar error in an Award, or the Arbitrator(s)
may  correct  such  errors  in the  Award  on his or  her  own  initiative.  The
Arbitrator(s)  will make any necessary and  appropriate  correction to the Award
within seven (7) calendar  days of receiving a request,  provided that the other
Party(ies) has a reasonable  opportunity to respond. The corrected Award will be
served upon the Parties.

     (H) The Award is  considered  final,  for  purposes of either the  Optional
Appeal Procedure pursuant to Rule 23 or for purposes of a judicial proceeding to
enforce,  modify  or vacate  the  award  pursuant  to Rule 24,  after  seven (7)
calendar  days of service of the Award,  if no request for a correction is made,
or as of the date of service of a corrected Award.

23.  OPTIONAL APPEAL
     PROCEDURE

     (A) The Appeal  Panel will  consist of three  neutral  members,  unless the
Parties  agree that there will be one neutral  member.  Upon receipt by the Case
Administrator  of the written  agreement of the Parties to the  Optional  Appeal
Procedure,  the Case Administrator will recommend to the Parties an Appeal Panel
and will make any disclosures  that are mandated by applicable law regarding the
candidates for the Panel. The Case  Administrator will seek the agreement of the
Parties as to the selection of Appeal Panel members. If the Parties do not agree
on the  composition of the Appeal Panel within seven (7) calendar days of having
received the Case  Administrator  recommendation  for the Appeal Panel, the Case
Administrator will appoint an Appeal Panel.

     (B) The procedure for filing and arguing an Appeal is as follows:

     (i) If all Parties have agreed to the Optional Appeal Procedure,  any party
may Appeal an Arbitration  Award that has been rendered  pursuant to Rule 22 and
has  become  final.  The  Appeal  must  be  served,  in  writing,  to  the  Case
Administrator and on the opposing  Party(ies) within fourteen (14) calendar days
after the Award has become  final.  The letter or other writing  evidencing  the
Appeal must specify those elements of the Award that are being Appealed and must
contain a brief statement of the basis for the Appeal.

     (ii) Within  seven (7)  calendar  days of the  service of the  Appeal,  the
opposing  Party(ies)  may serve on the Case  Administrator  and on the  opposing
Party(ies) a Cross-Appeal  with respect to any element of the Award.  The letter
or other writing  evidencing the Cross-Appeal must specify those elements of the
Award that are being  Appealed and must  contain a brief  statement of the basis
for the Cross-Appeal.

     (iii) The record on Appeal will consist of the stenographic or other record
of the  Arbitration  Hearing;  and  all  exhibits,  deposition  transcripts  and
affidavits that had been accepted into the record of the Arbitration  Hearing by
the  Arbitrator(s).  The Parties will cooperate with the Case  Administrator  in
compiling  the record on Appeal,  and the Case  Administrator  will  provide the
record  to  the  Appeal  Panel.  No  evidence  not  previously  accepted  by the
Arbitrator(s)  will be considered  by the Appeal Panel,  unless the basis of the
Appeal is  non-acceptance  by the  Arbitrator of certain  evidence or unless the
Appeal Panel  determines that there is good cause to re-open the record pursuant
to Rule 23(d).

     (iv) The Parties may elect to rely on the  memoranda  or briefs  previously
submitted  to the  Arbitrator(s).  In the  absence  of such  election,  the Case

                                      I-7


<PAGE>
<PAGE>

Administrator will obtain the agreement of the Parties on a briefing schedule.

     If no  agreement  is reached the Case  Administrator  will set the briefing
schedule.  Ordinarily,  only  opening  briefs (of no more than 25  double-spaced
pages) and  response  briefs (of no more than 15 double-spaced  pages)  will  be
allowed. The briefs may be in the form of a letter.

     (v) The Appeal Panel will conduct an oral  argument if all Parties  request
such  argument  or may  conduct  oral  argument,  in  complex  cases or  unusual
circumstances, on its own initiative.

     If there is to be oral  argument,  the Case  Administrator  will obtain the
agreement  of the Parties on both the date of such  argument  and the  duration,
including the allocation of time. In the absence of agreement,  the Appeal Panel
will set the date and duration of the oral argument, including the allocation of
time.

     (C) Once an Appeal  has been  timely  filed,  the  Arbitration  Award is no
longer   considered  final  for  purposes  of  seeking   judicial   enforcement,
modification or vacating pursuant to Rule 24.

     (D) The  Appeal  Panel  will  apply  the same  standard  of  review  as the
first-level  appellate  court in the  jurisdiction  would  apply  under  similar
circumstances  and will also apply the grounds for review  under the  applicable
Arbitration  review  statute.  The Appeal  Panel will  respect  the  evidentiary
standard  set forth in Rule 20(d).  The Panel may  affirm,  reverse or modify an
Award.

     It may not remand to the original Arbitrator,  but may reopen the record in
order to review evidence that had been improperly  excluded by the Arbitrator or
evidence  that is now  necessary in light of the Panel's  interpretation  of the
relevant  substantive law. A three-member Appeal Panel will make its decision by
majority vote and,  absent good cause for an extension,  will issue the decision
within  twenty-one  (21) calendar days of the date of either oral argument,  the
receipt  of the  new  evidence  or  receipt  of the  record  and of all  briefs,
whichever is applicable or later. Its decision will consist of a concise written
explanation, unless all Parties agree otherwise.

     (E) If a Party  refuses to  participate  in the Optional  Appeal  Procedure
after having agreed to do so, the Appeal Panel will maintain  jurisdiction  over
the Appeal and will  consider the Appeal as if all Parties  were  participating,
including  retaining  the  authority  to modify any Award or element of an Award
that had  previously  been  entered  in favor  of the  non-participating  Party,
assuming  it believes  that the record,  after  application  of the  appropriate
standard of Appeal, justifies such action.

     (F) J A M S/ENDISPUTE  will serve the Appeal Panel decision on the Parties.
Upon service of the Appeal Panel decision,  the Award will be final for purposes
of judicial review.

24.  ENFORCEMENT OF THE
     AWARD 

     Proceedings  to  enforce,  confirm,  modify  or  vacate  an  Award  will be
controlled by and conducted in conformity  with the Federal  Arbitration  Act, 9
U.S.C. Sec 1 et. seq. or applicable state law. The prevailing  Party(ies) in any
such proceeding will recover from the  non-prevailing  Party(ies) all reasonable
costs,  including attorneys' fees and expenses,  incurred in connection with the
judicial proceeding.

25.  CONFIDENTIALITY AND
     PRIVACY

     (A) The Parties,  the Case Administrator,  and the Arbitrator will maintain
the confidential nature of the Arbitration  proceeding and the Award,  including
the Hearing and the written  explanation  of the Award,  except as  necessary in
connection  with a judicial  challenge to or enforcement of an Award,  or unless
otherwise required by law or judicial decision.

     (B) The  Arbitrator  may issue  orders to protect  the  confidentiality  of
proprietary information, trade secrets or other sensitive information.

     (C)  Subject  to the  discretion  of the  Arbitrator  or  agreement  of the
Parties,  any person having a direct  interest in the Arbitration may attend the
Arbitration  Hearing.  The  Arbitrator  will have the  discretion to exclude any
non-Party from any part of a Hearing.

26.  WAIVER OF OBJECTION

     If a Party  becomes  aware of a  violation  or failure to comply with these
Rules and fails  promptly to object in  writing,  the  objection  will be deemed
waived,  unless the  Arbitrator  determines  that waiver will cause  substantial
injustice or hardship.

27.  SETTLEMENT AND
     CONSENT AWARD

     (A) The  Parties may agree,  at any stage of the  Arbitration  process,  to
submit the case to   J.A.M.S/ENDISPUTE   for  mediation.  The  J.A.M.S/ENDISPUTE
mediator  assigned  to the case  will not be an  Arbitrator  or a member  of the
Appeal Panel, unless the Parties so agree pursuant to Rule 27(b).

     (B) The Parties may also agree to seek the assistance of the  Arbitrator(s)
in reaching  settlement.  However,  the assistance of the  Arbitrator(s) in such
settlement  efforts  will not  disqualify  the  Arbitrator(s)  from  serving  as
Arbitrator(s) if settlement is not reached nor will such assistance be argued to
a reviewing court as the basis for vacating or modifying an Award.

     (C) If the Parties inform the Case  Administrator in writing that they have
reached a settlement,  the Arbitration will be deemed terminated. If the Parties
request,  the Arbitrator(s) will set forth the terms of the agreed settlement in
an Award which will be referred to as a Consent Award and will be binding on the
Parties.

28.  SANCTIONS

     The Arbitrator(s) may order appropriate sanctions for failure of a Party to
comply  with its  obligations  under any of these  Rules.  These  sanctions  may
include,  but are not limited to,  assessment of costs,  prohibition  of certain
evidence,  or in  extreme  cases  ruling on an issue  

                                      I-8



<PAGE>
<PAGE>

submitted  to  Arbitration adversely to the Party who has failed to comply.

29.  DISQUALIFICATION OF
     THE ARBITRATOR(S) AND
     EXCLUSION OF LIABILITY

     The Parties will not call the Arbitrator(s),  the Case Administrator or any
other J A M S/ENDISPUTE  employee as a witness or as an expert in any pending or
subsequent  litigation or other proceeding involving the Parties and relating to
the dispute which is the subject of the  Arbitration.  The  Arbitrator(s),  Case
Administrator,  and other  J A M S/ENDISPUTE  employees are also disqualified as
witnesses  or  experts.   The  Parties  will  defend  the  Arbitrator(s),   Case
Administrator  and J A M S/ENDISPUTE  from  any subpoenas  from outside  Parties
arising from the Arbitration. Neither the Arbitrator(s),  Case Administrator nor
J.A.M.S/ENDISPUTE is  a  necessary  party in any litigation or other  proceeding
relating  to the  Arbitration  or the  subject  matter of the  Arbitration,  and
neither the Arbitrator(s),  Case Administrator nor J.A.M.S /ENDISPUTE, including
its employees or agents,  will be liable to any Party for any act or omission in
connection with any Arbitration conducted under these Rules.

30.  FEES

     (A) Each Party will pay its pro-rata share of J.A.M.S/ ENDISPUTE's fees and
expenses as set forth in the  J.A.M.S/ENDISPUTE  fee  schedule  in effect at the
time of the  commencement  of the  Arbitration,  unless the  Parties  agree on a
different  allocation  of fees and  expenses.  The  allocation  of such fees and
expenses  will   not be  disclosed  to  the  Arbitrator(s).  J.A.M.S/ENDISPUTE's
agreement  to  render  services  is not only with the  Party,  but also with the
attorney or other representative of the Party in the Arbitration.

     (B)  J.A.M.S/ENDISPUTE  may require  that the Parties  deposit the fees and
expenses for the Arbitration  prior to the Hearing and may preclude a Party that
has failed to deposit its pro-rata or agreed-upon share of the fees and expenses
from offering evidence at the Hearing.  J.A.M.S/ ENDISPUTE may waive the deposit
requirement upon a showing of good cause.

     (C) The  Arbitrator  may  Award  against  any  Party  fees  that are due to
J A M S/ENDISPUTE.  In the event that one Party has not  appeared  and the other
Party from it has paid the full amount of the fees, the Arbitrator may Award the
defaulting  Party's share of the fee  obligation  against it and in favor of the
Party that has paid.

31.  BRACKETED (OR HIGH-
     LOW) ARBITRATION
     OPTION

     (A) At any time before the issuance of the Arbitration  Award,  the Parties
may agree,  in writing,  on minimum and maximum  amounts of damages  that may be
awarded  on each  claim or on all  claims in the  aggregate.  The  Parties  will
promptly notify the Case Administrator, and provide to the Case Administrator, a
copy of their  written  agreement  setting  forth the agreed  upon  maximum  and
minimum amounts.

     (B) The  Case  Administrator  will  not  inform  the  Arbitrator(s)  of the
agreement to proceed with this option nor of the agreed upon minimum and maximum
levels,  unless  all  Parties  agree  that  he  or  she  should  so  inform  the
Arbitrator(s).

     (C) The Arbitrator(s) will render the Award within twenty-one (21) calendar
days after the date of the closing of the Hearing or, if an Arbitration  Hearing
has been waived,  within  twenty-one  (21)  calendar  days after the date of the
Arbitrator(s) receiving all materials specified by the Parties. In rendering the
Award,  the  Arbitrator(s)  will apply the standard set forth in Rule 22(c). The
form of the final Award will be governed by Rule 22(e).

     (D) In the event  that the Award of the  Arbitrator(s)  is in  between  the
agreed upon minimum and maximum  amounts,  the Award will become final as is. In
the event that the Award of the  Arbitrator(s)  is below the agreed upon minimum
amount, the final Award issued will be at the agreed upon minimum amount. In the
event  that the Award of the  Arbitrator(s)  is above the  agreed  upon  maximum
amount, the final Award issued will be the agreed upon maximum amount.

32.  "FINAL OFFER (OR
     BASEBALL)" ARBITRATION
     OPTION

     (A) At least seven (7) calendar days before the  Arbitration  Hearing,  the
Parties will exchange and provide to the Case  Administrator  written  proposals
for the amount of money damages they would offer or demand,  as applicable,  and
that they  believe to be  appropriate  based on the  standard  set forth in Rule
22(c).  The Case  Administrator  will  promptly  provide a copy of the  Parties'
proposals to the Arbitrator(s), unless the Parties agree that they should not be
provided to the  Arbitrator(s).  Anytime  prior to the close of the  Arbitration
Hearing, the Parties remain free to exchange revised written proposals of offers
or demands,  which will  supersede  all prior  proposals.  The  revised  written
proposals will be provided to the Case  Administrator  who will promptly provide
them to the Arbitrator(s), unless the Parties agree otherwise.

     (B) If the  Arbitrator(s)  has been informed of the written  proposals,  in
rendering  the Award the  Arbitrator(s)  will select  between the Parties'  last
proposals,  choosing the proposal that the  Arbitrator(s)  finds most reasonable
and appropriate in light of the standard set forth in Rule 22(c).

     (C) If the  Arbitrator(s)  has not been informed of the written  proposals,
the  Arbitrator(s)  will render the Award as if pursuant to Rule 22, except that
the Award will  thereafter  be  adjusted  to conform to the  closest of the last
proposals and the closest of the last proposals will become the Award.

     (D) The Arbitrator  will render the Award within  twenty-one  (21) calendar
days after the date of the closing of the Hearing or, if an Arbitration  Hearing
has been waived,  within  twenty-one  (21)  calendar  days after the date of the
Arbitrator(s)  receiving all materials specified by the Parties. The form of the
final Award will be governed by Rule 22(e).

     (1) All decisions to be made under these Rules by the Case Administrator

benefits of this Agreement are the Registrable Securities.

               (b) Holders of Registrable Securities. A Person is deemed to be a
holder  of  Registrable   Securities   whenever  such  Person  owns  Registrable
Securities or has the right to acquire such Registrable  Securities,  whether or
not such  acquisition  has actually  been  effected and  disregarding  any legal
restrictions upon the exercise of such right.

               3.     Shelf Registration

               (a)  Filing  of  First  Shelf  Registration.  At any  time  after
February 1, 1997 so long as there are any  Transfer  Restricted  Securities  and
upon receipt of notice from VCU (the "NOTICE"), the Company shall file a "shelf"
registration  statement on any appropriate form pursuant to Rule 415 (or similar
rule that may be adopted by the  Commission)  under the Securities Act (a "SHELF
REGISTRATION"),  as  promptly  as  practicable  for the  amount  of  Registrable
Securities specified in the Notice. The Company agrees to

                                           2

<PAGE>
<PAGE>



use its best efforts to cause the Shelf  Registration  to become  effective  and
thereafter to keep it  continuously  effective for a period of three months from
the date on which the Commission  declares the Shelf  Registration  effective or
such shorter  period which will terminate  when all the  Registrable  Securities
covered  by the  Shelf  Registration  have  been  sold  pursuant  to such  Shelf
Registration.

               (b) Filing of Subsequent  Shelf  Registrations.  So long as there
are any Transfer Restricted Securities, upon receipt of a subsequent Notice (the
"SUBSEQUENT  NOTICE"),  the  Company  also  agrees  to file a  subsequent  Shelf
Registration  (the "SUBSEQUENT  SHELF  REGISTRATION") as promptly as practicable
for the amount of Registrable Securities specified in the Subsequent Notice. The
Company  agrees  to  use  its  best  efforts  to  cause  such  Subsequent  Shelf
Registration declared effective as soon as reasonably  practicable after filing.
The  Company  agrees  to use its best  efforts  to keep  each  Subsequent  Shelf
Registration  continuously  effective for a period of three months following the
dates on which each such Subsequent Shelf  Registration is declared effective or
until all Registrable Securities included therein have been sold, if earlier. In
the event that at the time the Company is required  to file a  Subsequent  Shelf
Registration, a previously filed Shelf Registration is effective covering all of
the Registrable  Securities,  the Company may satisfy its obligations as to such
Subsequent Shelf  Registration by extending the effectiveness of such previously
filed  Shelf   Registration   or   registration   statement  by  the  period  of
effectiveness required for such Subsequent Shelf Registration. The Company shall
notify  VCU  and  any  other  holders  of  Registrable  Securities  of any  such
extension.  The Company  further agrees to supplement or make  amendments to any
Subsequent  Shelf  Registration,  if  required  by  the  rules,  regulations  or
instructions  applicable to the registration  form utilized by the Company or by
the Securities Act or rules and regulations thereunder for shelf registration.

               4.     Hold-Back Agreements

               Restrictions on Public Sale by Holder of Registrable  Securities.
VCU and each other holder of  Registrable  Securities  agree that, to the extent
that the Company or other  shareholders of the Company conduct a public offering
of the Company's  securities,  if requested by the managing underwriters in such
underwritten  offering,  that such  holder of  Registrable  Securities  will not
effect any public sale or  distribution of securities of the Company of the same
class as the securities  included in such  registration  statement,  including a
sale  pursuant  to Rule 144 under the  Securities  Act  (except  as part of such
underwritten  registration),  during the 10-day  period prior to, and during the
30-day period beginning on, the closing date of each underwritten  offering made
pursuant  to such  registration  statement,  to the extent  timely  notified  in
writing by the Company or the managing underwriters.

               5.     Registration Procedures

               In connection with the Company's Shelf  Registration  obligations
pursuant to Section 3 hereof,  the Company  will use its best  efforts to effect
such  registration  to  permit  the  sale  of  such  Registrable  Securities  in
accordance with the intended method or

                                           3

               (a) use its best  efforts  to keep  such  Registration  Statement
continuously  effective and provide all requisite  financial  statements for the
period  specified in Section 3 of this  Agreement;  upon the  occurrence  of any
event  that  would  cause  any such  Registration  Statement  or the  Prospectus
contained therein (A) to contain a material  misstatement or omission or (B) not
to be effective and usable for resale of Transfer  Restricted  Securities during
the period  required  by this  Agreement,  the  Company  shall file  promptly an
appropriate amendment to such Registration Statement, in the case of clause (A),
correcting any such misstatement or omission,  and, in the case of either clause
(A) or (B),  use its  best  efforts  to  cause  such  amendment  to be  declared
effective and such Registration  Statement and the related  Prospectus to become
usable for their intended purpose(s) as soon as practicable thereafter;

               (b)  prepare and file with the  Commission  such  amendments  and
post-effective  amendments to the Registration  Statement as may be necessary to
keep the Registration Statement effective for the applicable period set forth in
Section 3 hereof,  as applicable,  or such shorter period as will terminate when
all Transfer Restricted  Securities covered by such Registration  Statement have
been sold;  cause the Prospectus to be supplemented  by any required  Prospectus
supplement,  and as so  supplemented  to be filed pursuant to Rule 424 under the
Act, and to comply fully with the  applicable  provisions  of Rules 424 and 430A
under the Act in a timely manner; and comply with the provisions of the Act with

Statement during the applicable period in accordance with the intended method or
methods of distribution  by the sellers  thereof set forth in such  Registration
Statement or supplement to the Prospectus;

               (c)  advise  the  underwriter(s),  if any,  and  selling  Holders

has  been  filed,  and,  with  respect  to  any  Registration  Statement  or any
post-effective  amendment thereto,  when the same has become effective,  (ii) of
any request by the Commission for  amendments to the  Registration  Statement or
amendments  or  supplements  to the  Prospectus  or for  additional  information
relating  thereto,  (iii) of the  issuance by the  Commission  of any stop order
suspending the  effectiveness of the Registration  Statement under the Act or of
the suspension by any state  securities  commission of the  qualification of the
Transfer Restricted Securities for offering or sale in any jurisdiction,  or the
initiation  of any  proceeding  for any of the preceding  purposes,  (iv) of the
existence of any fact or the  happening of any event that makes any statement of
a  material  fact  made  in the  Registration  Statement,  the  Prospectus,  any
amendment  or  supplement  thereto,  or any document  incorporated  by reference
therein  untrue,  or that  requires the making of any additions to or changes in
the  Registration  Statement or the  Prospectus in order to make the  statements
therein not misleading. If at any time the Commission shall issue any stop order
suspending  the  effectiveness  of the  Registration  Statement,  or  any  state
securities  commission  or  other  regulatory  authority  shall  issue  an order
suspending the qualification

                                           4

Securities,  including,  without  limitation,  information  with  respect to the
number of Registrable  Securities being sold to such underwriters,  the purchase
price being paid  therefor by such  underwriters  and with  respect to any other
terms  of the  underwritten  (or  best  efforts  underwritten)  offering  of the
Registrable  Securities  to be sold in such  offering;  and  make  all  required
filings of such  Prospectus  supplement or  post-effective  amendment as soon as

acts or  things  necessary  or  advisable  to  enable  the  disposition  in such
jurisdictions  of  the  Registrable   Securities  covered  by  the  Registration
Statement;  provided that the Company will not be required to qualify  generally
to do business in any jurisdiction  where it is not then so qualified or to take

to be made with the NASD),  fees and expenses of compliance  with  securities or
blue sky laws (excluding fees and  disbursements of counsel for the underwriters
or  selling  holders),   printing  expenses   (including  expenses  of  printing
certificates for the Registerable Securities in a form eligible for deposit with
Depositary Trust Company and of printing prospectuses), messenger, telephone and
delivery expenses and fees and disbursements of all independent certified public
accountants  of the Company  (including  the  expenses of any special  audit and
"cold comfort" letters required by or incident to such  performance),  (all such
expenses  being  herein  called  "REGISTRATION  EXPENSES")  will be borne by the
Company, regardless whether the Registration Statement becomes effective.

               (b) In connection  with each Shelf  Registration  hereunder,  the
holders of Registrable Securities being registered in such registration shall be
responsible  for the fees and  disbursements  of their own counsel and any fees,
discounts  or  commissions  of any brokers,  dealer  managers,  underwriters  or
similar securities industry professionals.

               7.     Indemnification

               (a)  Indemnification by Company.  The Company agrees to indemnify
and  hold  harmless,  to the  full  extent  permitted  by law,  each  holder  of
Registrable  Securities,  its officers,  directors and employees and each Person
who controls such holder (within the meaning of the Securities  Act) against all
losses,  claims,  damages,  liabilities  and  expenses  caused by any  untrue or
alleged  untrue  statement  of a material  fact  contained  in any  Registration
Statement,  Prospectus  or  preliminary  Prospectus  or any  omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements  therein not misleading,  except insofar as the
same are caused by or contained in any  information  furnished in writing to the
Company by such holder expressly for use therein;  provided,  however,  that the
Company  shall not be liable in any such case to the extent  that any such loss,
claim,  damage,  liability  or expense  arises out of or is based upon an untrue
statement or alleged  untrue  statement or omission or alleged  omission made in
any such  preliminary  Prospectus if (i) such holder failed to deliver a copy of
the Prospectus to the person asserting such loss,  claim,  damage,  liability or
expense after the Company had furnished such holder with a sufficient  number of
copies of the same and (ii) the  Prospectus  completely  corrected  such  untrue
statement or omission;  and  provided,  further,  that the Company  shall not be
liable  in any  such  case to the  extent  that any such  loss,  claim,  damage,
liability  or  expense  arises out of or is based  upon an untrue  statement  or
alleged untrue statement or omission or alleged  omission in the Prospectus,  if
such untrue statement or alleged untrue statement,  omission or alleged omission
is completely  corrected in an amendment or supplement to the Prospectus and the
holder of Registrable  Securities thereafter fails to deliver such Prospectus as
so  amended  or  supplemented  prior  to or  concurrently  with  the sale of the
Registrable  Securities  to the  person  asserting  such  loss,  claim,  damage,
liability or expense after the

                                           8

<PAGE>



Company had  furnished  such holder  with a  sufficient  number of copies of the
same.  The Company will also indemnify  underwriters,  selling  brokers,  dealer
managers and similar  securities  industry  professionals  participating  in the
distribution,  their  officers and  directors  and each Person who controls such
Persons  (within  the  meaning  of the  Securities  Act) to the same  extent  as
provided above with respect to the indemnification of the holders of Registrable
Securities, if requested.

               (b)  Indemnification  by Holder  of  Registrable  Securities.  In
connection  with  each  Shelf  Registration,   VCU  and  each  other  holder  of
Registrable  Securities will furnish to the Company in writing such  information
and affidavits as the Company reasonably requests for use in connection with any
Registration  Statement or Prospectus and agrees to indemnify and hold harmless,
to the full extent permitted by law, the Company, its directors and officers and
each Person who controls the Company  (within the meaning of the Securities Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue  statement of a material fact or any omission of a material fact required
to be  stated  in  the  Registration  Statement  or  Prospectus  or  preliminary
Prospectus or necessary to make the statements  therein not  misleading,  to the
extent,  but only to the  extent,  that such  untrue  statement  or  omission is
contained in any information or affidavit so furnished in writing by such holder
to the Company  specifically  for  inclusion in such  Registration  Statement or
Prospectus. In no event shall the liability of any selling holder of Registrable
Securities hereunder be greater in amount than the dollar amount of the proceeds
received by such holder upon the sale of the Registrable  Securities giving rise
to such  indemnification  obligation.  The Company  shall be entitled to receive
indemnities  from  underwriters,  selling  brokers,  dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as provided  above with respect to information so furnished in writing by
such Persons  specifically  for  inclusion  in any  Prospectus  or  Registration
Statement.

               (c) Conduct of Indemnification  Proceedings.  Any Person entitled
to  indemnification  hereunder  will (i) give prompt notice to the  indemnifying
party of any  claim  with  respect  to which it seeks  indemnification  and (ii)
permit such indemnifying  party to assume the defense of such claim with counsel
reasonably  satisfactory to the indemnified party;  provided,  however, that any
Person  entitled  to  indemnification  hereunder  shall have the right to employ
separate  counsel and to participate in the defense of such claim,  but the fees
and expenses of such counsel  shall be at the expense of such Person  unless (a)
the  indemnifying  party has  agreed to pay such  fees or  expenses,  or (b) the
indemnifying  party  shall have  failed to assure the  defense of such claim and
employ counsel  reasonably  satisfactory to such Person or (c) in the reasonable
judgment of any such  Person,  based upon advice of its  counsel,  a conflict of
interest may exist between such Person and the  indemnifying  party with respect
to such claims (in which case, if the Person notifies the indemnifying  party in
writing that such Person elects to employ separate counsel at the expense of the
indemnifying  party, the  indemnifying  party shall not have the right to assume
the  defense of such  claim on behalf of such  Person).  If such  defense is not
assumed by the indemnifying party, the indemnifying party will not be subject to
any liability for any settlement made without its consent (but such consent will
not be unreasonably withheld). No indemnifying party will be required to consent
to entry

                                           9

<PAGE>



of any  judgment  or enter  into any  settlement  which  does not  include as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified  party of a release  from all  liability in respect to such claim or
litigation.  An  indemnifying  party who is not  entitled  to, or elects not to,
assume the defense of a claim will not be obligated to pay the fees and expenses
of more than one counsel for all parties  indemnified by such indemnifying party
with respect to such claim, unless in the reasonable judgment of any indemnified
party a conflict of interest may exist  between such  indemnified  party and any
other of such indemnified parties with respect to such claim, in which event the
indemnifying  party  shall be  obligated  to pay the fees and  expenses  of such
additional counsel or counsels.

               (d) Contribution.  If for any reason the indemnification provided
for in the preceding  clauses (a) and (b) is unavailable to an indemnified party
or insufficient to hold it harmless as contemplated by the preceding clauses (a)
and (b),  then the  indemnifying  party shall  contribute  to the amount paid or
payable  by the  indemnified  party as a result of such loss,  claim,  damage or
liability in such  proportion as is appropriate to reflect not only the relative
benefits received by the indemnified party and the indemnifying  party, but also
the relative fault of the indemnified party and the indemnifying  party, as well
as any other relevant equitable considerations, provided that VCU and each other
holder of  Registrable  Securities  shall not be  required to  contribute  in an
amount  greater than the dollar amount of the proceeds  received by such holders
of Registrable Securities with respect to the sale of any securities.  No person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities  Act) shall be entitled to  contribution  from any person who was
not guilty of such fraudulent misrepresentation.

               8.     Participation in Underwritten Registrations

               If any of the Registrable  Securities covered by any of the Shelf
Registrations are to be sold in an underwritten  offering, the investment banker
or investment  bankers and manager or managers that will administer the offering
will be selected by VCU; provided that such investment bankers and managers must
be reasonably satisfactory to the Company.

               No  Person  may  participate  in  any  underwritten  registration
hereunder unless such Person (a) agrees to sell such Person's  securities on the
basis provided in any underwriting arrangements approved by the Persons entitled
hereunder  to approve  such  arrangements  and (b)  completes  and  executes all
questionnaires,  powers of attorney,  indemnities,  underwriting  agreements and
other  documents  required  under the terms of such  underwriting  arrangements.
Nothing in this  Section 8 shall be construed  to create any  additional  rights
regarding the  registration  of Registrable  Securities in any Person  otherwise
than as set forth herein.

            9. Miscellaneous

               (a) Remedies. Remedies for breach by the Company of its
obligations to register the Registrable Securities shall be as set forth herein.

               Each  holder of  Registrable  Securities,  in  addition  to being
entitled to exercise  all rights  provided  herein or granted by law,  including
recovery of damages,  will be  entitled  to specific  performance  of its rights
under this  Agreement.  The Company  agrees that  monetary  damages would not be
adequate  compensation  for any loss incurred by reason of a breach by it of the
provisions  of this  Agreement  and  hereby  agrees to waive the  defense in any
action for specific performance that a remedy at law would be adequate.


               (b) No Inconsistent Agreements.  The Company will not on or after
the  date of this  Agreement  enter  into  any  agreement  with  respect  to its
securities  which is  inconsistent  with the rights  granted  to the  holders of
Registrable  Securities  in this  Agreement  or  otherwise  conflicts  with  the
provisions hereof.  Other than as disclosed on Schedule 9(b) hereto, the Company
has not  previously  entered into any agreement  with respect to its  securities
granting  any  registration  rights to any  Person.  The  rights  granted to the
holders of Registrable  Securities hereunder do not in any way conflict with and
are not  inconsistent  with the rights  granted to the holders of the  Company's
securities under any such agreements.

               (c)  Amendments and Waivers.  The  provisions of this  Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given unless the Company has obtained the written  consent of holders
of at least 66-2/3% of the outstanding Registrable Securities.

               (d) Notices. All notices and other communications provided for or
permitted  hereunder  shall  be made in  writing  by  hand-delivery,  registered
first-class  mail,  telex,  telecopier,  or air courier  guaranteeing  overnight

duly  given:  at the time  delivered  by hand,  if  personally  delivered;  five
business days after being  deposited in the mail,  postage  prepaid,  if mailed;
when answered back, if telexed; when receipt acknowledged, if telecopied; and on
the  next  business  day if  timely  delivered  to an air  courier  guaranteeing
overnight delivery.

               (e)  Successors and Assigns.  This  Agreement  shall inure to the
benefit  of and be  binding  upon  the  successors  and  assigns  of each of the
parties,  including  without  limitation  and  without  the need for an  express
assignment, subsequent holders of Registrable Securities.

together shall constitute one and the same agreement.

               (g) Headings.  The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

construed in accordance with the internal laws of the State of New York.

               (i)  Severability.  In the  event  that  any  one or  more of the
provisions contained herein, or the application thereof in any circumstance,  is
held   invalid,   illegal  or   unenforceable,   the   validity,   legality  and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

               (j) Entire  Agreement.  This Agreement is intended by the parties

Agreement supersedes all prior agreements and understandings between the parties
with respect to such subject matter.

               (k)  Attorneys'  Fees.  In any  action or  proceeding  brought to
enforce any provision of this Agreement,  the successful party shall be entitled

any other available remedy.
