PART I


                                ITEM 1. BUSINESS

Overview

     Neurobiological   Technologies,   Inc.   ("NTI"  or  the  "Company")  is  a
biopharmaceutical  company  identifying  and  developing  potential  therapeutic
products  based on  advances  in  neuroscience  research.  NTI's  strategy is to
in-license  drug  candidates  that target major medical needs,  have shown clear
evidence of  preclinical  efficacy  and safety,  and appear to have a clear path
through clinical testing and regulatory approval.  NTI's experienced  management
team then  focuses on the drug  development  and clinical  testing  necessary to
bring its drug candidates to commercialization.

     The Company is currently evaluating three drug candidates in human clinical
trials:

     Corticotropin-Releasing Factor ("CRF") is a natural human peptide which the
Company believes has novel anti-inflammatory  properties. CRF is being evaluated
for its ability to reduce edema (swelling)  resulting from brain tumors,  and to
reduce the  inflammation  associated with rheumatoid  arthritis.  The Company is
currently  conducting  a  double  blind,  placebo-controlled  Phase  II trial in
patients with rheumatoid arthritis.  The Company has completed Phase I/II trials
of CRF in patients with brain tumors,  and expects to begin a follow-on Phase II
trial in fiscal 1997.

     Dynorphin A is a natural human  peptide being  developed for its ability to
provide relief from severe pain.  Dynorphin A initially is being evaluated as an
adjunct to morphine and other  opiates for the  management  of chronic and acute
severe pain.  The Company has  conducted  preliminary  studies which showed that
Dynorphin A, when administered in conjunction with morphine,  lowered the amount
of  morphine  needed to obtain an  analgesic  effect.  An  adjunct  to  morphine
allowing  lower doses of opioid may also reduce the  severity  and  frequency of
opioid-related adverse side effects, including respiratory depression, sedation,
and mental confusion.

     Memantine is being  evaluated as a potential  neuroprotectant  drug therapy
for the treatment of injured and dying neurons. Memantine is an orally available
compound which acts to modulate the N-methyl-D-aspartate  (NMDA) receptor in the
central  nervous  system.  Modulating  the NMDA  receptor  may  protect  against
neuronal injury and death associated with a number of conditions, including both
chronic conditions of neuropathic pain,  dementia,  and Alzheimer's  disease, as
well as acute  conditions of traumatic  brain injury and stroke.  The Company is
initially  planning to evaluate  Memantine for the treatment of neuropathic pain
and AIDS dementia and currently is conducting a Phase I  pharmacokinetics  trial
of  Memantine in normal  volunteers  and in AIDS  patients.  The Company is also
sponsoring  research by leading  neuroscientists  to  synthesize  and test novel
neuroprotective compounds.

<PAGE>

     Strategy


     NEW PRODUCT SOURCING

     The Company  identifies  new product  opportunities  through its network of
research scientist collaborators and stockholders.  With its Scientific Advisory
Board, the Company regularly  evaluates new product  opportunities  which may be
useful in a variety of medical  applications.  Early  access to  research in the
fields  of  neuropharmacology,  endocrinology,  and  immunology  has  led to the
identification  of the Company's lead products and continues to be the Company's
primary source of new product opportunities.  The compounds selected for further
commercialization  are those that the  Company  believes  target  major  medical
needs,  can be  rapidly  commercialized,  and for which the  Company  can obtain
proprietary rights.

     PRODUCT DEVELOPMENT

     After it selects a compound for clinical evaluation, the Company implements
a  development  plan  designed  to maximize  the  chances  for rapid  regulatory
approval.  The Company combines the drug discovery and development experience of
its  management  team and staff with the  expertise of its  Scientific  Advisory
Board  to  manage  product  development,   relying  primarily  upon  third-party
contractors to carry out manufacturing,  preclinical,  and clinical development.
These   contractors   are  selected   because  they  have  the   experience  and
qualifications necessary to conduct the required studies to the standards of the
Company and the Food and Drug Administration  ("FDA").  The Company also intends
to  establish  arrangements  for  the  manufacture,   packaging,   labeling  and
distribution of any products approved for marketing.

     FUTURE COMMERCIALIZATION

     As the Company  continues  its product  development  and  commercialization
efforts, it is seeking to enter into corporate alliances,  which may include the
granting of  licenses  and  marketing  rights for  selected  products in certain
geographic  regions  and  markets.  Through  alliances,  the Company may seek to
secure  additional  funding  for  the  continued  clinical  development  of  its
potential  products,  to secure  potential long term revenue  through royalty or
profit  sharing  arrangements,  to obtain  assistance  with  foreign  regulatory
approvals and to  capitalize  on the  technical,  development,  production,  and
marketing capabilities of its potential  collaborators.  Although the Company is
currently seeking corporate development partners for its drug candidates,  there
can be no assurance that any alliances will be entered into on terms  acceptable
to the Company, or if alliances are entered into, that they will be successful.

================================================================================
     MCORTICOTROPIN-RELEASING FACTORM
================================================================================

     CRF is a  natural  neuroendocrine  peptide  hormone  found  both  centrally
(within the brain) and  peripherally  (outside  the brain).  CRF was  originally
discovered  to be a key brain  hormone  involved in  stimulating  the release of
natural   corticosteroids,   which   modulate  the  body's   immune  system  and
inflammatory  response.  Much of the ensuing research on CRF has been related to
the activity of CRF within the brain.  Recently, the importance of CRF receptors
outside  the  brain  has also  been  recognized.  Research  by an NTI  scientist
collaborator  revealed  that  CRF  inhibited  the  acute  inflammatory  response
associated with a variety of forms of physical trauma.

     In response to tissue damage, small blood vessels become permeable, leading
to the  leakage  of fluid,  plasma  proteins,  and white  blood  cells  into the
surrounding  tissues,  which causes swelling,  a condition referred to as edema.
This fluid  leakage is primarily  due to the release of  inflammatory  mediators
that appear to facilitate  the opening of spaces between the  endothelial  cells
lining the blood  vessels.  CRF  appears to inhibit  acute  vascular  leakage by
acting on the endothelial and epithelial  cells lining and surrounding the blood
vessels near the site of tissue damage.

     Preclinical  studies  sponsored  by the Company have shown that CRF reduces
the leakage of fluids  through blood vessels at sites of tissue injury  produced
by trauma and inhibits the cascade of  inflammation  in several animal models of
inflammatory  disease.  Specifically,  the Company  has shown that CRF  injected
systemically  into  animals can reduce  brain edema  after  injury,  brain edema
associated  with cancer tumors,  inflammation  associated  with  arthritis,  and
swelling in muscle tissue following surgical incision.

     A therapeutic agent that inhibits edema associated with inflammation  would
be valuable in the  treatment of many kinds of injury and  illnesses,  some that
are life  threatening.  These include tumor  associated  edema,  traumatic brain
injury,   certain   forms  of  stroke,   rheumatoid   arthritis,   cosmetic  and
reconstructive  surgery,  neurosurgery,  and  burns and  other  wounds.  Current
therapies for these  conditions,  including  corticosteroids,  are in many cases
inadequate or have serious adverse side effects.  These side effects can include
muscle wasting, immunosuppression,  osteoporosis,  hyperglycemia,  glaucoma, and
other potentially dose limiting side effects.  Although CRF functions  naturally
to regulate  the release of natural  corticosteroids,  studies  sponsored by the
Company have shown that CRF exerts its  anti-inflammatory  action independent of
corticosteroid  release.  The Company believes,  based on CRF's  pharmacological
profile, that CRF may be efficacious without the adverse side effects associated
with current therapies.

     CRF has been safely  administered to several hundred healthy volunteers and
patients as reported in numerous  studies  published by third parties.  In early
human  clinical  trials  sponsored by the Company in over 200 patients,  CRF was
well tolerated and appeared to be safe.

     PRODUCT DEVELOPMENT STATUS

     Based on  observations  of CRF's action in several animal models of various
medical  conditions,  the Company has commenced  clinical  trials in a number of
indications including cerebral edema,  rheumatoid  arthritis,  and tissue damage
from surgical incision.
<PAGE>

     Cerebral  Edema  Cerebral  edema  is  swelling  in  the  brain,  a  serious
complication commonly associated with a number of medical conditions,  including
brain tumors, head injury, and stroke.

     The Company is initially  testing CRF for the  treatment of cerebral  edema
caused by brain tumors  (peritumoral brain edema). In these patients,  the tumor
promotes  increased  permeability  of the  small  blood  vessels  in the  brain,
resulting in the leakage of fluids into the brain, swelling of brain tissue, and
a consequent loss of neurological  function. The Company has completed two Phase
I/II pilot trials of CRF in patients  with  peritumoral  brain  edema.  In these
trials, CRF was well tolerated and appeared to improve neurological  function by
42% in seven  patients who were treated for seven days by  continuous  infusion.
Based on these  results,  we are in the process of  designing a larger  Phase II
trial planned to begin later this fiscal year.

     In addition to the current  clinical  program for  peritumoral  edema,  the
Company  is also  pursuing  a  pre-clinical  research  effort  to  assess  CRF's
potential to reduce cerebral edema  associated  with traumatic brain injury.  In
traumatic brain injury,  nerve tissue, blood vessels and the tissues surrounding
the brain are damaged.  This damage  results in swelling,  subsequent  decreased
flow of blood to the brain and  decreased  brain  function.  In addition,  edema
increases  pressure  inside  the skull,  which can lead to the fatal  rupture of
brain tissue through naturally occurring openings at the base of the skull.

     A stroke occurs when a blood vessel becomes  obstructed,  restricting blood
flow into or within  the  brain.  When brain  blood-flow  drops  below a certain
threshold,  brain tissue dies and edema  occurs.  The degree of edema is roughly
proportional  to the amount of brain  tissue  affected.  As with head  injuries,
edema following stroke promotes further  neurologic damage and may lead to fatal
rupture of brain tissue.

     Rheumatoid  Arthritis Rheumatoid arthritis ("RA") is a chronic inflammatory
disorder  characterized by pain,  swelling and damage to the body's joints.  The
onset of RA may either be acute,  resulting  in pain,  swelling,  and redness of
multiple joints,  or chronic,  resulting in gradual onset of symptoms  preceding
overt arthritis by several  months.  As the disease  progresses,  joint pain and
swelling result in functional impairment and disability. The currently available
therapies are not completely effective and their chronic use is often associated
with serious toxicities.

     The  Company's   preclinical  results  demonstrated  that  CRF  has  potent
anti-inflammatory  properties  that may be useful for the  treatment  of RA. The
Company  believes CRF's ability to inhibit  microvascular  leakage may limit the
migration of inflammatory cells and the flow of inflammatory  molecules into the
rheumatic joint, and thus reduce the swelling and tissue damage  associated with
the condition.

     The Company  completed a pilot Phase I/II clinical  trial in December 1995.
In this trial, CRF was well tolerated and appeared to reduce joint  inflammation
and pain in the five evaluable  patients.  In March 1996, the Company  announced
the start of a 100 patient double-blind  placebo-controlled Phase II trial in RA
patients.  This trial,  conducted in several centers throughout the country,  is
designed to evaluate CRF's potential to reduce joint inflammation.  The protocol
calls  for  self  administration  of CRF or  placebo  once  a day  for 14  days.
Improvement  measures  include  tender joint  count,  swollen  joint count,  and
several other  criteria  defined by the American  College of  Rheumatology.  The
Company  expects to complete  enrollment  of patients in this trial in September
1996.

     Cosmetic and Reconstructive Surgery Tissues injured by surgery may manifest
all of the classical aspects of inflammation,  including swelling and pain. Such
post-surgical  symptoms are generally  treated with analgesics and  occasionally
corticosteroids.

     The Company  has  completed  a Phase I/II trial  designed  to evaluate  the
effect of CRF on the swelling associated with blepharoplasty, a cosmetic surgery
that removes  excess skin and fat from the area around the eyelids.  The Company
used this indication as a model for the treatment of a number of other potential
cosmetic and  reconstructive  surgical  applications.  The results of this trial
demonstrated  that CRF is safe and well  tolerated  when  used as a  single-dose
treatment for  post-surgical  facial  swelling.  In addition,  all CRF treatment
groups experienced reduced average  post-surgical  swelling compared to placebo.
Due to the relatively small number of subjects tested and the large  variability
between  subjects,  statistical  significance  was not achieved.  The Company is
seeking a partner before developing this indication further.

     Additional Indications Because of the anti-inflammatory  action of CRF, the
Company has in the past investigated various other potential indications. During
1995, the Company  initiated two clinical trials of CRF in patients with asthma.
The results of these trials showed that there was no  statistically  significant
difference  in  improvement  of  asthma  symptoms  between  those  who  received
treatment  compared to those who received placebo.  The results may have been in
part due to the short  duration  of  treatment,  and the  Company  is  currently
evaluating different treatment regimens in asthma patients.

     Second Generation  Anti-Inflammatory  Product The Company is engaged in the
synthesis and  exploration  of a family of small  peptide  analogues of CRF. The
objective  of this  research is to generate a second  generation  orally  active
anti-inflammatory  product having CRF's pharmacological activity to expand CRF's
clinical and market potential.

================================================================================
     MDYNORPHIN AM
================================================================================

     Dynorphin A is a natural human  peptide being  evaluated for its ability to
provide  analgesia for severe pain. The Company has conducted  several  clinical
trials of  Dynorphin  A to  evaluate  its  potential  to enhance  the  analgesia
provided by opioids  (generally  morphine)  in patients  with severe  pain.  The
Company  has  evaluated  Dynorphin A as an adjunct to morphine in both the acute
and chronic severe pain settings. In these preliminary trials, patients who were
administered  Dynorphin  A as an  adjunct  to  opioid  used  substantially  less
morphine and experienced comparable pain relief.

     Morphine,  first prescribed in the nineteenth  century,  remains one of the
most effective analgesics  available,  and is the standard by which other opioid
analgesics are evaluated.  Morphine and other opioids are used as analgesics for
relief of both acute and chronic  severe pain.  However,  opioids are associated
with  adverse  side  effects  which can be dose  limiting.  Opioid side  effects
include respiratory depression,  nausea, sedation, and constipation. The Company
believes that  administration  of Dynorphin A as an adjunct to morphine in order
to  lower  the  amount  of  opioid  needed  to  provide  analgesia  may  provide
significant  clinical benefit to patients whose pain is insufficiently  relieved
by chronic opioid therapy, or who wish to avoid the adverse side effects.

     In  preclinical  studies,  Dynorphin  A has been shown to restore  morphine
induced  analgesia when used in conjunction with morphine in animals tolerant to
morphine.  In addition,  the Company and its collaborators  have discovered that
certain Dynorphin A peptides can provide analgesia by 

<PAGE>

mechanisms  different than those  commonly  associated  with opioids.  In animal
studies, these peptides provided analgesia when administered systemically in the
absence of opioids,  with potency  similar to that of morphine.  The Company has
developed a synthetic  version of  Dynorphin A [Dynorphin  A-(1-13)],  which has
been  evaluated in several human  clinical  trials for its  potential  analgesic
effect. In these trials,  Dynorphin A has been well tolerated and has not caused
sedation or mental confusion.

     Chronic Pain Morphine and other  opioids are used as long term  medications
for the relief of chronic pain,  such as back pain or pain induced by cancer and
cancer  therapies.  Over  time,  pain may  increase  and the body may  develop a
tolerance  to opioids,  leading to the need for  progressively  higher  doses to
maintain the same degree of pain relief.  Drawing on the  preclinical  data that
Dynorphin A restores morphine induced analgesia in animals tolerant to morphine,
the Company has conducted  three clinical trials in patients with chronic severe
pain.  During the past year,  the  Company  concluded  a pilot Phase II study of
Dynorphin A in nine chronic pain  patients.  In this trial,  patients were given
50% of their normal  maintenance dose of morphine followed by either Dynorphin A
or placebo.  Dynorphin A appeared to be more effective than placebo in providing
pain relief and extended the period before patients re-medicated with morphine.

     Acute Pain Opioids are also used as short term analgesics to provide relief
of acute pain.  However,  opioids can  produce a number of  undesirable  central
nervous  system side  effects.  The most  dangerous  side effect is  respiratory
depression,   which  may  occur  in  patients   following   administration   for
post-surgical pain. An adjunct to opioids that would allow lower doses of opioid
while maintaining  satisfactory pain relief may have the potential to reduce the
frequency and severity of adverse opioid side effects. To evaluate the potential
of Dynorphin A to maintain satisfactory  analgesia in combination with a reduced
use of morphine,  the Company has conducted a  double-blind,  placebo-controlled
Phase II trial in  patients  with  post-surgical  severe  pain.  In this  trial,
Dynorphin A or placebo was administered  intravenously to 31 patients four times
over a 24-hour  period  following hip or knee  replacement  surgery.  During the
trial, patients were free to self-administer morphine and the amount of morphine
used by each  patient  was  recorded.  A primary  endpoint  of the trial was the
amount of morphine required to maintain  sufficient pain relief.  The results of
this trial  showed that  Dynorphin A reduced the amount of morphine  required to
adequately  manage  post-operative  pain.  The median  total  morphine  usage by
patients receiving placebo was 44% greater than for patients receiving Dynorphin
A.

     Ongoing  research The Company has an active research program to investigate
the  potential  therapeutic  uses of  Dynorphin  A  peptides.  As a part of this
research  effort,  scientists  are  investigating  the  mechanism  of  action of
Dynorphin A. In animal studies,  Dynorphin A has been shown to relieve pain as a
single agent by mechanisms distinct from morphine and other opioids. The Company
continues to evaluate  this  finding and to search for the  receptor  associated
with Dynorphin A.

================================================================================
     MMEMANTINEM
================================================================================

     Memantine  is a compound  in a class of  potential  neuroprotective  agents
called NMDA receptor antagonists.  Recent research has indicated that modulating
the NMDA receptor may protect against  neuronal injury and death associated with
a number of medical conditions.
<PAGE>

     Increasing   evidence  from  several  independent   research   laboratories
indicates that  overstimulation of NMDA receptors  contributes to the injury and
death of  neurons  in a  variety  of acute  neurological  conditions,  including
traumatic  brain  injury,   hypoxic/ischemic  injury  secondary  to  stroke  and
prolonged  open heart or brain  surgery,  as well as  chronic  neurodegenerative
diseases,   including   neuropathic   pain,   dementia,   Alzheimer's   disease,
Huntington's disease, and Amyotrophic Lateral Sclerosis.  There are currently no
neuroprotective  treatments approved for any of the pathologies  associated with
NMDA receptor overstimulation.

     Nerve  cells in the  brain  communicate  by  sending  signals  to excite or
inhibit   each   other.   These   signals  are  sent  by   compounds   known  as
neurotransmitters. The principal excitatory neurotransmitter is glutamate, which
binds to the NMDA  receptor  embedded in the cell  membrane of the neuron.  When
glutamate  binds to the receptor,  a channel into the neuron opens through which
charged  calcium  molecules  flow.  Normally,  the presence of calcium  triggers
chemical  reactions  that cause the neuron to change its  electrical  charge and
fire a message to neighboring neurons.  This basic function of the NMDA receptor
is essential for movement,  sensation, memory, and cognition. In certain medical
conditions,  glutamate levels  surrounding  neurons are elevated,  which has the
effect of  overstimulating  the NMDA  receptor,  causing the calcium  channel to
remain  open for too long.  In these  situations,  excessive  amounts of calcium
enter the neuron,  causing it to swell and burst,  releasing  internal stores of
glutamate into the  surrounding  area.  This glutamate  further  stimulates NMDA
receptors  on  neighboring  neurons,  causing a cascade of  neuronal  cell death
throughout the area.

     Scientists  are now trying to find a way to prevent the damaging  influx of
excess calcium into neurons.  One approach is to prevent  glutamate from binding
to the receptor,  which can be accomplished by using a blocker,  otherwise known
as a competitive NMDA receptor antagonist. If such an antagonist interferes with
the binding  process for too long, it may impede the normal  functioning  of the
NMDA  receptor,   causing  side  effects  including  hallucinations,   paranoia,
delirium, and amnesia.  Memantine,  on the other hand, is a non-competitive NMDA
receptor   antagonist  which  may  interfere   relatively   little  with  normal
functioning,  while  reducing the abnormal  signals  associated  with  excessive
calcium influx.

     PRODUCT DEVELOPMENT STATUS

     Neuropathic  Pain  Neuropathic  pain is associated with a type of injury to
neurons that produces abnormal pain signals,  and frequently includes persistent
pain  in the  absence  of an  obvious  stimulus.  The  condition  includes  pain
resulting  from  irritation or injury to peripheral  nerves and  destruction  of
terminals  of  small  nerves  as  a  result  of  diabetes  and  chemotherapeutic
neuropathies. In diabetic patients, high levels of blood sugar may damage nerves
which  transmit pain signals,  leading to the  experience of  neuropathic  pain.
Current  treatments for this  condition are limited,  and may only provide short
term benefit.

     NMDA receptor stimulation appears to be an important mechanism contributing
to neuropathic pain.  Memantine has inhibited  abnormal pain signals through its
modulation of the NMDA receptor in several  animal models of  neuropathic  pain.
Based on the  results  of these  studies,  the  Company  is  planning a trial to
evaluate Memantine for the treatment of neuropathic pain.

     AIDS Recent research indicates that infection of the central nervous system
with HIV, the virus associated with AIDS,  initiates the overstimulation of NMDA
receptors,  leading to neuronal damage.  

<PAGE>

Such damage may result in an assortment of neurological complications, including
loss of  cognition,  movement  and  sensation,  referred  to as  AIDS  dementia.
Approximately  one-half of children and one-third of adults with AIDS eventually
develop these symptoms.  There are currently no therapies  specifically directed
towards HIV-associated neuronal damage.

     Many AIDS patients may also experience painful peripheral  neuropathies due
to  overstimulation  of the NMDA receptors.  A predominantly  sensory neuropathy
occurs in the later stages of AIDS,  which results in a burning pain of the feet
and pain from anything that touches the skin.  Walking in particular  may become
extremely  difficult.  Effective  treatments  are  still  unavailable  for  this
incapacitating  condition,  and  anti-retroviral  therapy for AIDS may unmask or
potentiate this type of neuropathic pain.

     Memantine has been shown to reduce NMDA  receptor-mediated  neuronal damage
in both in vitro  experiments  as well as animal  models.  The  neuronal  injury
caused by AIDS was shown to be modified  by  antagonists  of the NMDA  receptor,
including Memantine.

     The Company is now conducting a Phase I clinical trial to verify the safety
and pharmacokinetics (serum half-life) of Memantine in AIDS patients and healthy
volunteers.

     In the second  quarter of this fiscal year, NTI expects to begin a Phase II
clinical  trial in  collaboration  with  the  Division  of AIDS of the  National
Institutes of Health to evaluate the ability of Memantine to provide relief from
dementia and  neuropathic  pain symptoms in AIDS  patients.  The trial  protocol
submitted under our Investigational New Drug application recently allowed by the
Food and Drug Administration  calls for the enrollment of 120 AIDS patients with
painful peripheral  neuropathies and symptoms of dementia, all of whom will have
been treated with an FDA-approved  anti-retroviral drug for at least eight weeks
prior to study entry.  The Division of AIDS plans to conduct the clinical trial,
and the Company will supply  Memantine and have the  exclusive  right to use the
resulting data for commercialization.

     AIDS Dementia The Division of AIDS trial will evaluate  Memantine's ability
to  ameliorate  dementia  in AIDS  patients.  Memantine's  efficacy  in reducing
neurological  symptoms  associated  with  AIDS  dementia  will be  evaluated  by
assessing the patients' neuropsychological function and quality of life.

     Neuroprotection  Research  Program  The  Company  has  initiated a research
program directed toward the identification of novel  neuroprotective  compounds.
The Company is sponsoring research by leading  neuroscientists to discover novel
NMDA receptor antagonists.

     MADDITIONAL PRODUCT OPPORTUNITIESM
================================================================================

     The Company's network of scientist  stockholders and collaborators has been
instrumental in identifying new product  opportunities for evaluation by NTI. In
addition to the current  products  under  clinical  development,  several  other
possible  product  opportunities  are being considered by the Company for future
development.

Patents and Proprietary Technology

     Patents  and  other  proprietary  rights  are  critical  to  the  Company's
business. The Company's policy is to file patent applications seeking to protect
technology,  inventions and  improvements  to its 

<PAGE>

inventions that are considered important to the development of its business. The
Company has also  sought,  and intends to continue to seek,  to obtain  licenses
from third  parties to patent rights  covering the  technology,  inventions  and
improvements  that the Company  considers  important to the  development  of its
business.  The Company is obligated to pay  royalties  pursuant to these license
agreements and is responsible for the costs of patent prosecution of a number of
the patent applications to which it has exclusive licenses. In addition, most of
the license agreements can be terminated by the licensor if the Company does not
demonstrate diligence in commercializing the licensed rights.

     The  Company  may be  required  to obtain  additional  licenses  from third
parties in order to continue to develop its existing  product  candidates and to
expand its product  development  program.  There can be no  assurance  that such
licenses will be available on commercially reasonable terms, if at all.



<PAGE>

     The  patent  positions  of  pharmaceutical  and  biotechnology   companies,
including NTI, are uncertain and involve complex legal and factual questions. In
addition,  the coverage  claimed in a patent  application  can be  significantly
reduced  before a patent is  issued.  Consequently,  the  Company  does not know
whether  any of its  patent  applications,  or the  patent  applications  it has
licensed  from  others,  will result in the issuance of patents or if any of the
patents  which have  issued or may issue will  provide  significant  proprietary
protection.  Since patent  applications  are maintained in secrecy until patents
are issued in the  United  States or their  foreign  counterparts,  if any,  are
published,  the Company  cannot be certain that it or any licensor was the first
to file patent  applications  for such inventions.  Moreover,  the Company might
have to participate in interference  proceedings declared by the U.S. Patent and
Trademark  Office to  determine  priority of  invention,  which could  result in
substantial  cost to the Company,  even if the eventual  outcome were favorable.
There can be no assurance that the Company's  patents,  or the patents which the
Company has  licensed,  will be held valid or  enforceable  by a court or that a
competitor's technology or product would be found to infringe such patents.

     A number of  pharmaceutical  and  biotechnology  companies and research and
academic institutions have developed technologies,  filed patent applications or
received  patents on various  technologies  that may be related to the Company's
business. Some of these technologies,  applications or patents may conflict with
the Company's or any of its licensors' technologies or patent applications. Such
conflict  could limit the scope of the patents,  if any, that the Company may be
able to  obtain or to which it has a  license  or  result  in the  denial of the
Company's patent  applications or the patent  applications which the Company has
licensed.  In addition, if patents that cover the Company's activities have been
or are issued to other  companies,  there can be no  assurance  that the Company
would be able to obtain  licenses to these  patents,  at all, or at a reasonable
cost, or be able to develop or obtain alternative technology.

     In addition to patent  protection,  the  Company  relies upon trade  secret
protection for its  confidential  and proprietary  information.  There can be no
assurance that others will not independently  develop  substantially  equivalent
proprietary information and techniques or otherwise gain access to the Company's
trade secrets or disclose such  technology or that the Company can  meaningfully
protect its trade secrets.

     CRF The  Company  has a  non-exclusive  worldwide  license  to issued  U.S.
patents and U.S. patent  applications  covering the composition of matter of CRF
and various CRF analogues,  together with the corresponding  foreign patents and
patent applications. The Company also has exclusive rights to patents and patent
applications covering uses of CRF and analogues of CRF. In addition, the Company
has an exclusive worldwide license to patents and a patent application  covering
novel  peptide  analogues  of CRF. The Company is  responsible  for the costs of
prosecuting  the patent  applications  related to CRF for which it has exclusive
licenses.  In addition to the patents and pending  applications  the Company has
licensed from others, the Company has filed a use patent application  related to
CRF.

     Dynorphin A The Company holds licenses to patents  covering the composition
of matter of Dynorphin A, as well as analogues and fragments of Dynorphin A. The
Company  also  has  exclusive  licenses  to  patents  covering  certain  uses of
dynorphins and has a pending application for the use of fragments of Dynorphin A
in direct peripheral non-opioid pain relief.
<PAGE>

     Memantine  The Company has an exclusive  license to a series of patents and
patent  applications  relating  to  certain  non-ophthalmic  uses of  Memantine.
Certain of these patents and patent applications cover the use of antagonists of
NMDA receptor  mediated neuronal damage to treat  AIDS-related  neuronal damage.
Memantine and similar  compounds are generally  considered to be such compounds.
In addition,  certain of these patents and patent  applications cover the use of
Memantine   for  certain  other  medical   indications,   including   peripheral
neuropathy. The Company also has an option to license exclusively any patentable
compounds or combination  of compounds  discovered in the course of the research
the Company is sponsoring at Children's Hospital of Boston, Massachusetts.

Manufacturing

     NTI currently uses outside  contractors  to  manufacture  compounds for the
Company's preclinical studies and clinical trials. The manufacturers of clinical
products  have  represented  to the Company  that they are  qualified to produce
drugs under FDA  regulations  and that they follow  current  Good  Manufacturing
Practice  requirements  ("cGMP")  prescribed  by the FDA.  The Company  performs
audits on  manufacturers  from time to time to assess  compliance  with the cGMP
regulations.  Dynorphin A, CRF, and Memantine are  manufactured  by  established
methods using chemical  synthesis and are  manufactured  to NTI  specifications.
Alternative  cGMP  suppliers  of the bulk  drugs  and of  finished  dosage  form
products are available to the Company.

     The  Company  currently  has no  plans  to build  or  develop  an  in-house
manufacturing  capability.  The  Company  has agreed in one of its  Dynorphin  A
license  agreements  that, under certain limited  circumstances,  it would use a
manufacturing facility affiliated with the licensor to manufacture the compounds
licensed thereunder.

Government Regulation

     Regulation  by  governmental  authorities  in the  United  States and other
countries  will be a significant  factor in the  production and marketing of any
products  which may be developed  by the  Company.  The nature and the extent to
which such regulation may apply to the Company will vary depending on the nature
of any such  products.  All of the Company's  products  will require  regulatory
approval prior to commercialization.  In particular,  human therapeutic products
are  subject  to  rigorous  preclinical  and  clinical  testing  and  other  FDA
requirements  in the United  States and similar  health  authorities  in foreign
countries.  Various  federal and, in some cases,  state statutes and regulations
also  govern  or  influence  the  manufacturing,   safety,  labeling,   storage,
recordkeeping  and marketing of such products,  including the use,  manufacture,
storage,  handling  and  disposal  of  hazardous  materials  and  certain  waste
products. The process of obtaining these approvals and the subsequent compliance
with appropriate federal, state and foreign statutes and regulations require the
expenditure of substantial resources.  The Company cannot yet accurately predict
when it  might  first  submit  for  approval  any  products  to the FDA or other
regulatory review agency.

     In order to test clinically,  produce and market products for diagnostic or
therapeutic  use, a company  must comply with  mandatory  procedures  and safety
standards  established by the FDA and comparable  agencies in foreign countries.
Before  beginning human clinical testing of an  investigational  new drug in the
United States, a company must file an IND and receive no objection from the FDA.
This  application   contains  a  summary  of  the  chemistry  and  manufacturing
information  and  of  the  

<PAGE>

preclinical  studies which were carried out to characterize the drug,  including
toxicity and safety,  as well as an in-depth  discussion  of the human  clinical
studies which are being proposed.

     The human clinical  testing program  required for approval by the FDA of an
investigational   new  drug  typically  involves  a  time-consuming  and  costly
three-phase  process.  In Phase I, clinical  trials are  conducted  with a small
number of patients or healthy  volunteers to determine the early safety  profile
and the pattern of drug  distribution  and metabolism.  Phase II clinical trials
are conducted  with groups of patients  afflicted with a target disease in order
to determine  preliminary  efficacy,  optimal  dosage and  expanded  evidence of
safety.  When initial human testing is performed in patients  afflicted with the
disease,  rather than healthy  volunteers,  such studies may provide preliminary
evidence of efficacy  traditionally obtained in Phase II trials. Such trials are
frequently  referred  to as "Phase  I/II"  trials.  In Phase  III,  large-scale,
multi-center,  comparative clinical trials are conducted with patients afflicted
with the specific disease in order to provide enough data for statistical  proof
of efficacy and safety required by the FDA and non-U.S. regulatory agencies.

     Clinical    trials    may   be    sponsored    by   a    company    or   be
"investigator-sponsored." An investigator-sponsored clinical trial is defined as
a  clinical  trial  conducted  by an  investigator  under an IND  issued in such
investigator's own name, rather than in a company's name.

     The FDA  closely  monitors  the  progress  of each of the  three  phases of
clinical  testing  and may, at its  discretion,  reevaluate,  alter,  suspend or
terminate  the  testing  based on the data which have been  accumulated  to that
point and its assessment of the risk/benefit ratio to the patient.  Estimates of
the total time required for carrying out such clinical  testing vary between two
and ten years.  Upon completion of such clinical  testing,  a company  typically
submits a New Drug Application  ("NDA") to the FDA which summarizes and analyzes
the results and  observations  of the  clinical  trials.  The NDA also  provides
detailed manufacturing information. Based on its review of the NDA, the FDA will
decide  whether or not to approve  the drug.  This  review  process can be quite
lengthy,  and approval may not be granted at all.  Thus,  the process of seeking
and  obtaining  approval for the marketing of a new  pharmaceutical  product can
require a number of years and  substantial  funding.  There can be no  assurance
that any  approvals  will be granted  on a timely  basis,  if at all.  Among the
requirements  for  product  approval  is  the  requirement  that  each  domestic
manufacturer of the product conform to the FDA's cGMP regulations, which must be
followed  at  all  times.  In  complying  with  standards  set  forth  in  these
regulations, manufacturers must continue to expend time, money and effort in the
area of production and quality control to ensure full technical compliance.

     Once  the  sale of a  product  is  approved,  FDA  regulations  govern  the
manufacturing process and marketing activities, and a post-marketing testing and
surveillance  program may be required to continuously  monitor a product's usage
and effects.  Product  approvals may be withdrawn if compliance  with regulatory
standards is not maintained. Other countries, in which any products developed by
the Company may be marketed,  impose a similar regulatory process. For marketing
outside the United  States,  the Company  also is subject to foreign  regulatory
requirements  governing human clinical trials and marketing  approval for drugs.
The requirements  governing the conduct of clinical trials,  product  licensing,
pricing and reimbursement vary widely from country to country.

Competition

     Competition in the biopharmaceutical industry is intense and is expected to
increase. The development and sale of drugs for the treatment of the therapeutic
targets being pursued by the

<PAGE>

Company is highly  competitive.  There are existing therapies approved and under
development  for each of these  therapeutic  targets.  There can be no assurance
that the  Company  will  develop  products  that  will be as  efficacious  or as
cost-effective  as  currently-marketed   products.  The  Company  has  exclusive
licenses to patent rights covering certain uses of CRF, Memantine, and Dynorphin
A. However,  certain of the Company's licenses for CRF, Memantine, and Dynorphin
A are  non-exclusive  and there is no composition of matter patent in the United
States for Memantine.  Consequently,  others may develop, manufacture and market
products that could compete with those being developed by the Company.



<PAGE>

     The Company will be faced with  intense  competition  from  pharmaceutical,
chemical and biotechnology companies both in the United States and abroad in its
attempt to  discover,  develop and market such drugs.  Companies  that  complete
clinical trials,  obtain required  regulatory  approvals and commence commercial
sales of their  products  before  their  competitors  may achieve a  significant
competitive   advantage.   In  addition,   significant  levels  of  research  in
biotechnology  and medicine occur in universities  and other nonprofit  research
institutions.  These entities have become  increasingly active in seeking patent
protection and licensing revenues for their research results.

     The Company believes that its ability to compete  successfully  will depend
on its  ability  to create  and  maintain  scientifically  advanced  technology,
develop proprietary products,  attract and retain scientific  personnel,  obtain
patent  or  other  protection  for  its  products,  obtain  required  regulatory
approvals and  manufacture  and  successfully  market  products  either alone or
through other  parties.  Most of the Company's  competitors  have  substantially
greater  financial,  marketing  and human  resources  than those of the Company.
Therefore, the Company expects to encounter significant competition.

Human Resources

     As of  August  31,  1996,  the  Company  had 25  employees.  The  Company's
scientific  staff  includes  individuals  with  expertise in clinical  medicine,
chemistry,    biochemistry,    cell    biology,    immunology,     pharmacology,
neuropharmacology, pharmaceutics and pharmaceutical manufacturing.

     It is the Company's policy that each employee enter into a  confidentiality
agreement  which contains  provisions  generally  prohibiting  the disclosure of
confidential  information to anyone outside the Company and requiring disclosure
to the  Company of ideas,  developments,  discoveries  or  inventions  conceived
during  employment and  assignment to the Company of proprietary  rights to such
matters related to the business and technology of the Company.

Risk Factors

     Except  for  the  historical  information  contained  herein,  this  report
contains forward looking  statements that involve risks and  uncertainties.  The
Company's  actual results could differ  materially  from those discussed in this
report.  Factors that could cause or contribute to such differences include, but
are not limited to, those discussed  below.  The forward  looking  statements in
this report represent the Company's judgement as of the date of this report. The
Company  disclaims,  however,  any intent or  obligation to update these forward
looking statements.

     Early Stage of  Development;  Technological  Uncertainty NTI is at an early
stage  of  development  and  currently  has  no  marketed  products.  All of the
Company's  potential  products  are  in  research,  preclinical  development  or
clinical development, and no revenues have been generated from product sales. To
date,  most of the Company's  resources  have been dedicated to the research and
development of selected candidate  pharmaceutical  products, and there can be no
assurance that the Company will be able to develop a candidate product that will
receive required  regulatory  approvals or be successfully  commercialized.  The
Company is currently evaluating three potential products in early stage clinical
trials. Results attained in preclinical studies and in such early stage clinical
trials are not  necessarily  indicative  of results  that will be obtained  upon
further  human  clinical  testing.   The  potential   products  currently  under
development by the Company will require significant  additional

<PAGE>

clinical  testing  prior  to  submission  of  any  regulatory   application  for
commercial  use. Such  activities  will require  substantial  resources and will
necessitate the raising of substantial additional capital.

     The  Company's  potential  products  are  subject  to the risks of  failure
inherent in the development of products based on new  technologies.  These risks
include the  possibilities  that any or all of the  potential  products  will be
found to be unsafe, ineffective or toxic, or otherwise fail to receive necessary
regulatory  clearances;  that  the  products,  if safe  and  effective,  will be
difficult  to  manufacture  on a large  scale or  uneconomical  to market;  that
proprietary  rights of third  parties will  preclude the Company from  marketing
products,  or that third  parties  market or will market  superior or equivalent
products.  There can be no assurance that the Company's  development  activities
will result in any commercially viable products.  The Company does not expect to
be able to commercialize any products for a number of years, if at all.

     Future  Capital Needs;  Uncertainty of Additional  Funding The Company will
require substantial additional funds to conduct the research and development and
preclinical  and clinical  testing of its  potential  products and to market any
products that may be developed. Although the Company currently plans to contract
with third parties to manufacture  clinical and commercial  scale  quantities of
its potential  products,  to the extent the Company  subsequently  determines to
establish its own manufacturing facilities, the Company will require substantial
additional  capital.  The  Company's  capital  requirements  depend on  numerous
factors,  including the progress of its research,  preclinical  development  and
clinical  development  programs,   the  time  and  cost  involved  in  obtaining
regulatory approvals, the cost of filing, prosecuting,  defending, and enforcing
patent claims and other intellectual  property rights,  competing  technological
and  market   developments,   changes  in  the   Company's   existing   research
relationships,   the   ability  of  the  Company  to   establish   collaborative
relationships,  the development of commercialization activities and arrangements
and the purchase of additional capital equipment.  The Company believes that its
available cash and investments will be sufficient to fund its operations through
the end of fiscal 1997.  Thereafter,  the Company will need to raise substantial
additional  capital to fund its  operations.  The  Company  intends to seek such
additional funding through public or private financings,  collaborative or other
arrangements  with corporate  partners,  or from other sources.  There can be no
assurance that additional financing will be available from any of these sources,
or, if available, that it will be available on acceptable terms. The Company may
seek to  raise  additional  funds  whenever  market  conditions  so  permit.  If
additional funds are raised by issuing equity  securities,  further  significant
dilution  to  existing  stockholders  may  result.  If  adequate  funds  are not
available, the Company may be required to delay, scale back, or eliminate one or
more of its research, discovery, or development funds or to obtain funds through
entering  into  arrangements  with  collaborative  partners  or others  that may
require the Company to relinquish rights to certain of its technologies, product
candidates or products that the Company would not otherwise relinquish.

     Dependence on Third Parties The Company has only limited internal resources
and thus the Company has relied and will  continue to rely heavily on others for
research,  development,  manufacturing  and  commercialization  of its potential
products.  The Company has entered into various  arrangements (many of which are
non-exclusive) with consultants,  academic collaborators,  licensors, licensees,
contractors  and others,  and it is dependent  upon the level of commitment  and
subsequent    success   of   these   outside   parties   in   performing   their
responsibilities.   Certain  of  these  agreements  place   responsibility   for
preclinical  testing and human clinical  trials and for preparing and submitting
submissions for regulatory  approval for potential products on the collaborator,
licensor or contractor. Should such collaborator, licensor or 
<PAGE>


contractor  fail to perform,  the Company's  operating  results may be adversely
affected.



<PAGE>

     The Company has entered into  certain  agreements  and licenses  with third
parties, a number of which require the Company to pay royalties. The Company has
relied on scientific,  technical,  clinical,  commercial and other data supplied
and disclosed by others in entering into these  agreements and will rely on such
data in support of applications to enter human clinical trials for its potential
products.  Although the Company has no reason to believe  that this  information
contains  errors or omissions of fact,  there can be no assurance that there are
no errors or omissions of fact that would change  materially  the Company's view
of the future  likelihood  of FDA  approval  or  commercial  viability  of these
potential products.

     Government  Regulation  and  Product  Approval  The FDA and state and local
agencies,  and  comparable  agencies  and entities in foreign  countries  impose
substantial   requirements   on  the   manufacturing   and  marketing  of  human
therapeutics  through  lengthy and  detailed  laboratory  and  clinical  testing
procedures,  sampling activities and other costly and time consuming procedures.
Satisfaction  of these  requirements  typically  takes  many  years  and  varies
substantially based on the type, complexity, and novelty of the drug. The effect
of government  regulation may be to delay for a  considerable  period of time or
prevent  the  marketing  of any product  that the Company may develop  and/or to
impose costly procedures upon the Company's activities,  the result of which may
be to furnish an advantage to its  competitors.  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 or at all.  Any such delay in obtaining or failure
to obtain such approvals would  adversely  affect the marketing of the Company's
proposed  products and its ability to earn  product  revenues or  royalties.  In
addition,  success in preclinical or early stage clinical trials does not assure
success  in  later  stage  clinical  trials.  As  with  any  regulated  product,
additional   government   regulations  may  be  promulgated  which  could  delay
regulatory  approval of the Company's  potential  products.  Adverse  government
regulation which might arise from future  legislation or  administrative  action
cannot be predicted.

     Uncertainty of Protection of Patents and  Proprietary  Rights The Company's
success will depend, in large part, on its ability to obtain or license patents,
protect trade secrets and operate without infringing upon the proprietary rights
of  others.  A  substantial   number  of  patents  have  been  issued  to  other
pharmaceutical,  biotechnology and biopharmaceutical companies.  Moreover, other
competitors  may have filed  patent  applications  for,  or may have been issued
patents or may obtain  additional  patents and  proprietary  rights relating to,
products or processes competitive with those of the Company.

     There can be no assurance that any of the patent  applications  licensed to
the Company will be approved, that the Company will develop proprietary products
that are  patentable,  that any issued  patents  licensed  to the  Company  will
provide the Company with adequate  protection  for its inventions or will not be
challenged by others,  or that the patents of others will not impair the ability
of the  Company to do  business.  The patent  position  of  biotechnology  firms
generally is highly uncertain,  involving  complex legal and factual  questions,
and has recently been the subject of much litigation.  No consistent  policy has
emerged from the United States Patent and Trademark Office regarding the breadth
of claims  allowed  or the degree of  protection  afforded  under  biotechnology
patents.  Finally,  there can be no assurance that others will not independently
develop similar products,  duplicate any of the Company's potential products, or
design around any potential patented products of the Company. As a result, there
can be no assurance that patent applications relating to the Company's potential
products or processes will result in patents being issued,  or that patents,  if
issued, will provide protection against  competitors who successfully  challenge
the Company's  patents,  obtain 
<PAGE>

patents  that may have an  adverse  effect on the  Company's  ability to conduct
business, or be able to circumvent the Company's patent position. In view of the
time delay in patent  approval and the secrecy  afforded  United  States  patent
applications,  the Company does not know if other  applications  that would have
priority over the Company's applications have been filed.

     Manufacturing  Limitations  The  Company  currently  does  not have its own
manufacturing  facilities to  manufacture  products  under cGMP. The Company has
established   arrangements  with  contract  manufacturers  to  supply  potential
products for preclinical  and clinical  trials and intends to establish  similar
arrangements  for the  manufacture,  packaging,  labeling  and  distribution  of
products, if approved for marketing.  If the Company's contractors are unable to
supply sufficient  quantities of product  candidates  manufactured in accordance
with cGMP on acceptable  terms,  the Company's  preclinical  and human  clinical
testing  schedule would be delayed.  If the Company should  encounter  delays or
difficulties  in  establishing  relationships  with  manufacturers  to  produce,
package and distribute its products, market introduction and subsequent sales of
such products would be adversely affected. Moreover, contract manufacturers that
the Company may use must adhere to cGMP regulations  enforced by the FDA through
its  facilities   inspection   program.   If  these  facilities  cannot  pass  a
pre-approval plant inspection, the FDA pre-market approval of the products would
be  adversely  affected.  The  Company's  dependence  on third  parties  for the
manufacture of products may adversely affect the Company's results of operations
and its  ability to develop and  deliver  products  on a timely and  competitive
basis.

     Risk of  Product  Liability  Clinical  trials  or  marketing  of any of the
Company's potential products may expose the Company to liability claims from the
use of such products.  The Company's product liability  insurance does not cover
commercial  sales of  products.  The  Company  has a limited  amount of  product
liability insurance to cover liabilities arising from clinical trials. There can
be no  assurance  that the  Company's  insurance  will be  adequate to cover any
liabilities arising from the Company's clinical trials, that the Company will be
able to obtain product  liability  insurance  covering  commercial  sales or, if
obtained,  that  sufficient  coverage can be acquired at a reasonable  cost.  An
inability to obtain  insurance at acceptable  cost or otherwise  protect against
potential product liability claims could prevent or inhibit commercialization of
any products developed by the Company.

     Dependence  on  Qualified  Personnel  and  Advisors  The  Company is highly
dependent  upon its  scientific  and  management  staff and on  consultants  and
advisors,  the loss of whose services might  significantly delay the achievement
of planned  development  objectives.  In  addition,  the Company is dependent on
collaborators  at research  institutions.  Recruiting  and  retaining  qualified
personnel,  collaborators,  advisors  and  consultants  will be  critical to the
Company's success.  There is intense competition for such qualified personnel in
the area of the  Company's  activities,  and there can be no assurance  that the
Company will be able to continue to attract and retain the  personnel  necessary
for the development of the Company's business.  The Company's planned activities
will require  additional  expertise in areas such as clinical trial  management,
regulatory affairs,  manufacturing,  and marketing. Such activities will require
the  addition of new  personnel  including  management  and the  development  of
additional expertise by existing management personnel.  The inability to acquire
such services or to develop such expertise could have a material  adverse effect
on the Company's operating results.

     Possible  Enforcement  Proceedings  In late  January  1996,  two  executive
officers of the Company  purchased an aggregate of 1,600 shares of the Company's
Common Stock prior to the Company's
<PAGE>

proposed  public  offering of common stock.  After these  officers  informed the
Company's  outside legal  counsel of such  purchases,  such counsel  advised the
Company  that such  purchases  constituted  a violation  of Rule 10b-6 under the
Securities  and Exchange Act of 1934, as amended.  Rule 10b-6  prohibits,  among
other things, bids or purchases of an issuer's stock by executive officers of an
issuer on whose behalf a distribution  is being made for a certain period before
commencement of offers or sales of the issuer's stock.  The SEC has instituted a
voluntary  informal  inquiry into this matter.  It is possible  that the SEC may
seek  enforcement  action  against the Company  and/or the officers who made the
purchases. Given the preliminary stage of the inquiry, there can be no assurance
as to what action,  if any,  the SEC will take,  or the effect of such action on
the Company.  Any actions taken by the SEC with respect to the matter may have a
material  adverse  effect on the  Company's  financial  position  and results of
operations.

     Volatility of Stock Price;  Limited Market  Capitalization The market price
of the  shares of Common  Stock,  like that of the  common  stock of many  other
biotechnology  companies,  has been and is  likely  to  continue  to be,  highly
volatile. Factors such as the results of preclinical studies and clinical trials
by the Company, or its competitors,  other evidence of the safety or efficacy of
products  of the  Company or its  competitors,  announcements  of  technological
innovations  or new  therapeutic  products  by the  Company or its  competitors,
government regulation, health care legislation,  developments in patent or other
proprietary  rights of the  Company  or its  competitors  including  litigation,
fluctuations in the Company's operating results,  and market conditions for life
sciences stocks in general could have a significant adverse impact on the future
price of the Common Stock. In addition,  the average daily trading volume of the
Company's  Common Stock since public  trading of the Common Stock  commenced has
been relatively low compared to that of other  biopharmaceutical  companies.  To
the extent this  trading  pattern  continues,  the price of the Common Stock may
fluctuate  significantly  as a result of changes  in demand for such  shares and
sales of stock by stockholders.

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

Overview

     Neurobiological   Technologies,   Inc.   ("NTI"  or  the  "Company")  is  a
biopharmaceutical  company  identifying  and  developing  potential  therapeutic
products  based on  advances  in  neuroscience  research.  NTI's  strategy is to
in-license  drug  candidates  that target major medical needs,  have shown clear
evidence of  preclinical  efficacy  and safety,  and appear to have a clear path
through clinical testing and regulatory approval.  NTI's experienced  management
team then  focuses on the drug  development  and clinical  testing  necessary to
bring its drug candidates to commercialization.

     The Company is currently  advancing three product  candidates through human
clinical trials. NTI is developing Corticotropin-Releasing Factor (CRF), a human
peptide for  reduction of edema and  inflammation  in patients with brain tumors
and rheumatoid arthritis. NTI has also licensed and is developing Dynorphin A, a
natural analgesic peptide, for use with morphine in managing severe pain. NTI is
also developing Memantine,  an orally available NMDA receptor antagonist,  which
has potential as a neuroprotective agent. Memantine is initially being developed
for  treatment  of  neuropathic  pain  and  AIDS-related  dementia.  Significant
additional  preclinical  testing and clinical  testing will be required prior to
submission  of any  regulatory  application  for  the  commercial  use of  these
products. There can be no assurance that future clinical trials will demonstrate
an adequate level of safety or efficacy for commercialization.
<PAGE>

     Since 1987 when the Company was founded, NTI has applied  substantially all
of its  resources  to its research and  development  programs.  The Company is a
development  stage  company,  has not  received  any  revenue  from  the sale of
products, and does not anticipate receiving revenue from the sale of products in
the near future. The Company has incurred losses since its inception and expects
to incur  substantial,  increasing losses over the next several years due to the
ongoing and planned research and development efforts.

Results of Operations

     The Company's  research and development  expenses increased from $2,645,000
in fiscal 1994 to  $4,452,000  in fiscal 1995 and  decreased  to  $4,321,000  in
fiscal  1996.  The  decrease  in  fiscal  1996  was  due to  lower  non-clinical
development  activity,  including  toxicology  studies, as compared to the prior
year.  The  increase  from 1994 to 1995 was  primarily  due to  expansion of the
Company's  preclinical  studies,  funding of  clinical  trials and the hiring of
technical personnel.

     General and  administrative  expenses  increased from  $1,261,000 in fiscal
1994 to  $1,512,000  in fiscal 1995 and  decreased to  $1,397,000 in fiscal 1996
primarily due to changes in use of legal and other professional services.

     Interest  income  increased  from  $236,000  in fiscal  1994 to $633,000 in
fiscal 1995 and  decreased to $506,000 in fiscal 1996,  primarily due to changes
in average cash balances.

     The Company expects to incur  substantial  additional  costs in fiscal 1997
primarily  for  preclinical  studies  and  clinical  trials for its  development
programs  and  related  administrative  support.  The Company  expects  that its
expenditures will continue to increase as its products move through Phase II and
potentially, Phase III clinical trials.

Liquidity and Capital Resources

     The Company  expects its cash  requirements  to increase  significantly  in
future  periods.  Future cash  requirements  will  depend on  numerous  factors,
including:  the  progress on research  and clinical  development  programs;  the
in-licensing  of  potential  drug  candidates;  the time and costs  involved  in
obtaining  regulatory  approvals;  the  ability  of  the  Company  to  establish
collaborative  arrangements;   product  commercialization  activities;  and  the
acquisition of manufacturing or laboratory facilities.  Since NTI uses qualified
third-party  contractors to conduct preclinical studies and clinical trials, and
to  manufacture  clinical  quantities  of its  products,  the  Company  does not
anticipate  incurring  significant capital expenditures during fiscal 1997. Over
the same period,  the number of employees is not expected to grow  significantly
from current levels.

     During the 1996 fiscal  year,  the Company  completed a public  offering of
stock,  raising $7.1 million in net proceeds.  From  inception  through June 30,
1996,  the Company has raised a total of $29.2  million in net proceeds from the
sale of common and preferred stock.

     The  Company  believes  that  its  available  cash,  cash  equivalents  and
investments  of $10.8  million  as of June 30,  1996  are  adequate  to fund its
operations  through the end of fiscal 1997.  NTI will need to raise  substantial
additional  capital to fund subsequent  operations.  The Company intends to seek
such funding through public or private  financings,  arrangements with corporate
partners,  or from other sources. The Company may seek to raise additional funds
whenever  market  conditions  permit.

<PAGE>

However  there can be no  assurance  that funding will be available on favorable
terms from any of these sources, if at all.

Notes to Financial Statements

Neurobiological Technologies, Inc. (a development stage company)

     NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     Organization

     Neurobiological   Technologies,   Inc.   ("NTI"  or  the  "Company")  is  a
biopharmaceutical  company  identifying  and  developing  potential  therapeutic
products  based on  advances  in  neuroscience  research.  NTI's  strategy is to
in-license  drug  candidates  that target major medical needs,  have shown clear
evidence of  preclinical  efficacy  and safety,  and appear to have a clear path
through clinical testing and regulatory approval.  NTI's experienced  management
team then  focuses on the drug  development  and clinical  testing  necessary to
bring its drug candidates to commercialization.

     Use of estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted accounting principles requires management to make certain estimates and
assumptions  that affect the amounts  reported in the financial  statements  and
accompanying notes. Actual results could differ from those estimates.

     Cash and investments

     Cash and cash equivalents  include  investments with original maturities of
90 days or less.  Short-term  investments  consist of investments  with original
maturities  of  greater  than 90 days  but  less  than a year,  while  long-term
investments  are those that mature  greater than one year from the balance sheet
date.  The Company has not  realized  any losses on its  investments,  which are
highly liquid and subject to little risk.  Furthermore,  the Company reduces its
credit  risk by  limiting  the amount of credit  exposure  to any one  financial
institution.

     In fiscal 1995,  the Company  adopted  Statement  of  Financial  Accounting
Standards  No.  115,  "Accounting  for  Certain  Investments  in Debt and Equity
Securities"  ("SFAS 115").  SFAS 115 addresses the  accounting and reporting for
investments in equity securities that have readily  determinable fair values and
for all investments in debt securities. Adoption of this statement had no effect
on the Company's financial position or results of operations.

     All of the Company's investment  securities are classified as available for
sale and are stated at amounts which  approximate fair market value. The Company
did not have  any  material  realized  or  unrealized  gains  or  losses  on its
investments.  Realized gains or losses,  amortization of premiums,  accretion of
discounts and earned interest are included in investment income.

<PAGE>


     The following is a summary of available-for-sale  securities at fair market
value, which approximates amortized cost, at June 30, 1996 and 1995:

                                                  1996               1995

          Corporate obligations              8,041,959          5,480,407

          Commercial paper                   2,346,545          1,586,549

          Accrued interest                     115,684             74,638

          Total                            $10,738,050         $8,149,094
- - -------------------------------------------------------------------------------

     Such  available-for-sale  securities have been recorded at June 30, 1996 as
cash and cash equivalents ($4,580,407),  short-term investments ($4,642,153) and
long-term  investments  ($1,515,490).  By policy, the Company does not invest in
securities that mature in more than 18 months.  At June 30, 1996, all securities
in the investment portfolio are scheduled to mature in less than 14 months.

     Property and equipment

     Property and equipment is stated at cost.  Depreciation is calculated using
the straight-line method based on estimated useful lives of 5 to 7 years.

     The balances at June 30, 1996 and 1995 consisted of the following:

                                                     1996             1995

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

                                                  356,660          266,621

         Less Accumulated depreciation           (127,393)         (69,518)

                                                 $229,267        $ 197,103
- - --------------------------------------------------------------------------------

     Patents and licenses

     Patents and licenses  consist of the costs  relating to license  agreements
covering  certain  patent  rights  to the  Company's  products.  The  costs  are
amortized  using the  straight-line  method  over the shorter of the life of the
patent or its economic  useful life.  Accumulated  amortization at June 30, 1996
and 1995 was $217,846 and $152,626, respectively.

     Net loss per share

     Net loss per share is computed using the weighted  average number of shares
of common stock  outstanding.  Common  equivalent  shares from stock options and
warrants are excluded  from the  computation  as their effect is  anti-dilutive,
except that,  pursuant to Securities and Exchange  Commission  Staff  Accounting
Bulletins,  common  equivalent  shares from stock,  stock  options and  

<PAGE>

warrants  issued at prices below the public  offering  price during the 12-month
period  prior  to  the  initial  public  offering  have  been  included  in  the
calculation as if they were  outstanding for all the periods  presented  through
December  31,  1993 (using the  treasury  stock  method and the  initial  public
offering price of $8 per share for common stock, stock options and warrants, and
the as-if-converted method for preferred stock).

     All shares in the accompanying financial statements have been retroactively
adjusted  to reflect the  9.333-for-one  reverse  stock  split that  occurred in
February 1994.

     NOTE 2. LEASE

     The Company  leases its current  premises in Richmond,  California  through
April 2000.  Rent expense for the years ended June 30, 1996,  1995, and 1994 was
$143,000, $81,000 , and $64,000, respectively.

     At June 30, 1996,  future minimum  payments under leases with initial terms
of one year or more consisted of the following:

            1997                               $132,000

            1998                                132,000

            1999                                132,000

            2000                                110,000

                                               $506,000

     Effective  with the closing of the  Company's  initial  public  offering in
February 1994,  the Board of Directors  authorized  25,000,000  shares of common
stock,  $.001 par value,  and  5,000,000  shares of preferred  stock,  $.001 par
value.

     Preferred stock

     At June 30, 1993, preferred stock consisted of 5,691,000 shares of series A
preferred  stock.  Each share  converted  into 1.25 shares of series B preferred
stock  upon the  consummation  of the series B  preferred  stock  financing.  In
December 1993, the Company issued  2,657,881 shares of Series B preferred stock.
In February 1994, all preferred stock automatically  converted into common stock
and the Company effected a 9.333-for-1 reverse split.

     Warrants to purchase common stock

     At June 30, 1996,  warrants to purchase 798,393 shares of common stock were
outstanding at a weighted  average  exercise price of $6.83 per share. Of these,
37,286  shares of common  stock at a price of $5.60 were  issued  for  licensing
rights and consulting  services and have  expiration  dates through June,  2001;
warrants to purchase 381,107 shares at $7.47 per share were issued in connection
with the Series A preferred  offering and expire on April 9, 1997;  and warrants

share were issued to the  underwriters  of the
<PAGE>

initial public offering and the 1996 public offering,  respectively,  and expire
on February 15, 1999 and 2001, respectively.

     Stock option plan

     Under the Company's 1993 Stock Plan,  1,500,000 shares of common stock have
been reserved for issuance. In general, options are granted at fair market value
on the date of the grant, have a term of 10 years and become  exercisable over a
period of up to 48 months. However, 90,000 options outstanding,  of which 13,000
are  exercisable at June 30, 1996,  are subject to accelerated  vesting based on
the achievement of certain performance-based milestones.

     Information as to activity under the plan is as follows:

stock were exercisable at prices ranging from $2.88 to $8.00

     Stock purchase plan

     Effective February 1994, the Company established an employee stock purchase
plan (the "Plan") under which the employees may purchase  common stock at 85% of
the lower of the share price at the  beginning  or end of a  designated  period.
Under the Plan,  50,000  shares have been  reserved for issuance of which 42,342
have been issued through June 30, 1996.

     NOTE 4. INCOME TAXES

     The  Company  uses the  liability  method to account  for  income  taxes as
required by FASB  Statement  No.109,  "Accounting  for Income Taxes." Under this
method,  deferred tax assets and liabilities are determined based on differences
between  financial  reporting  and tax bases of assets and  
<PAGE>

liabilities  and are measured  using  enacted tax rules and laws that will be in
effect when the differences are expected to reverse.

<PAGE>

     Significant  components of the Company's deferred tax assets (in thousands)
are as follows at June 30, 1996 and 1995:

                                                         1996          1995    
- - -------------------------------------------------------------------------------
Net operating loss carryforwards                  $     6,500    $    4,950
Research and development credit carryforward              700           690
Capitalized research and development                      450            --
- - -------------------------------------------------------------------------------
Gross deferred tax assets                               7,650         5,640
Valuation allowance                                    (7,650)       (5,640)
Net deferred tax assets                           $        --    $       --
- - -------------------------------------------------------------------------------

     The valuation  allowance  increased by $2,010,000  and $2,400,000 in fiscal
1996 and 1995, respectively.

     At June 30, 1996,  the Company has net  operating  loss  carryforwards  for
federal  and  state  income  tax  purposes  of  approximately   $18,000,000  and
$5,000,000  respectively,  which expire in the tax years 1996 through 2010.  The
Company has federal tax credit  carryforwards of approximately  $4,000,000 which
expire in the tax years 2006 through 2010.

     During the years ended June 30, 1991 and 1994,  the Company  experienced  a
"change of ownership" as defined in Section 382 of the Internal Revenue Code. As
a  result,   utilization   of  the  company's  net  operating  loss  and  credit
carryforwards  incurred  prior to the "change of ownership" may be subject to an
annual   limitation.   If  an  additional  "change  of  ownership"  occurs,  the
availability  of the  Company's  net  operating  loss and  credit  carryforwards
incurred  subsequent to the 1994 "change of ownership" may also be subject to an
annual limitation.

     NOTE 5. POSSIBLE ENFORCEMENT PROCEEDINGS

     In late January 1996,  two executive  officers of the Company  purchased an
aggregate of 1,600 shares of the  Company's  Common Stock prior to the Company's
proposed  public  offering of common stock.  After these  officers  informed the
Company's  outside legal  counsel of such  purchases,  such counsel  advised the
Company  that such  purchases  constituted  a violation  of Rule 10b-6 under the
Securities  and Exchange Act of 1934, as amended.  Rule 10b-6  prohibits,  among
other things, bids or purchases of an issuer's stock by executive officers of an
issuer on whose behalf a distribution  is being made for a certain period before
commencement of offers or sales of the issuer's stock.  The SEC has instituted a
voluntary  informal  inquiry into this matter.  It is possible  that the SEC may
seek  enforcement  action  against the Company  and/or the officers who made the
purchases. Given the preliminary stage of the inquiry, there can be no assurance
as to what action,  if any,  the SEC will take,  or the effect of such action on
the Company.  Any actions taken by the SEC with respect to the matter may have a
material  adverse  effect on the  Company's  financial  position  and results of
operations.

States shall be manufactured substantially in the United States.

         E. In order to establish  exclusivity for Licensee,  CMCC hereby agrees
that it shall not, without Licensee's prior written consent,  grant to any other
commercial  party a license to make,  have made, use, lease and/or sell Licensed
Products or to use the Licensed  Processes in the Field of Use during the period
of time in which this Agreement is in effect,  except as otherwise  specified in
this  Agreement  or as  required  by law to grant  rights to the  United  States
Government.

         F. Licensee shall have the right to enter into sublicensing  agreements
with respect to any of the rights,  privileges,  and licenses granted hereunder,
subject to the terms and conditions hereof. Such sublicenses will terminate upon
the termination of Licensee's rights granted herein unless events of default are
cured by Licensee or Sublicensee within thirty (30) days of notification by CMCC
of default and/or as provided by the terms of this Agreement.

deleting economic terms when and as appropriate.

         H. Licensee agrees to provide to CMCC notice of any sublicense  granted

agreements.  Licensee  further agrees to forward to CMCC annually a copy of such
reports received by Licensee from its  sublicensees  during the preceding twelve
(12)  month  period  as shall be  pertinent  to a royalty  accounting  under the
applicable sublicense.

         I. Licensee shall advise CMCC in writing of any consideration  received
from  sublicensees.  Licensee shall not accept from any sublicensee  anything of
value in lieu of cash payments to discharge  sublicensee's  payment  obligations
under any sublicense  granted under this Agreement,  without the express written
permission of CMCC, which permission shall not be unreasonably withheld.

         J. CMCC  agrees  that if  Licensee  has  provided  to CMCC  notice that

the event CMCC terminates  this Agreement for any reason  provided  hereinafter,

the effective date of said  termination,  written notice of said  termination at
the address  specified  by Licensee to CMCC in  Licensee's  notice to CMCC under
Paragraph H of this Article II. CMCC agrees that upon the  sublicensee's  notice
as described below

grant to such sublicensee  license rights and terms equivalent to the sublicense
rights and terms which the  sublicense  shall have granted to said  sublicensee;
provided that the  sublicensee  shall remain a sublicensee  under this Agreement
for a period of at least sixty (60) days following  receipt of notice from CMCC.
Sublicensee  shall  during  said sixty (60) day  period  provide to CMCC  notice
wherein  the  sublicensee:  (i)  reaffirms  the  terms  and  conditions  of this
Agreement as it relates to the rights the sublicensee has been granted under the
sublicensee;  (ii)  agrees to abide by all of the terms and  conditions  of this
Agreement  applicable to  sublicensees  and to discharge  directly all pertinent
obligations of Licensee which Licensee is obligated hereunder to discharge;  and
(iii)  acknowledges that CMCC shall have no obligations to the sublicensee other
than its obligations set forth in this Agreement with regard to Licensee.

         K. The license  granted  hereunder shall not be construed to confer any
rights upon Licensee by implication,  estoppel or otherwise as to any technology
not described in the Patent Rights.

         L. As a result of an  agreement  dated  December 7, 1994,  and existing
prior to this  Agreement,  CMCC has agreed not to assert,  and  Licensee  hereby
agrees  not to assert,  any of the  Patent  Rights  resulting  from U.S.  patent
application  [CONFIDENTIAL TREATMENT REQUESTED],  its continuations,  or foreign
counterparts (further described in Appendix 2) against  [CONFIDENTIAL  TREATMENT
REQUESTED], or its sublicensees or assignees with regard to the following fields
of use: any manufacture,  use or sale of [CONFIDENTIAL TREATMENT REQUESTED]. The
obligations  of this Paragraph L shall expire with the expiration or termination
of the December 7 agreement.

                           ARTICLE III. DUE DILIGENCE

         A. Licensee shall use its good faith and diligent  efforts to bring one
or more  Licensed  Products  and/or  Licensed  Processes  to  market  as soon as
reasonably practicable,  consistent with sound and reasonable business practices
and judgment,  through a thorough,  vigorous and diligent commercial development
program.  Thereafter,  Licensee  agrees that until  expiration or termination of
this  Agreement,  Licensee  shall continue  active and diligent  efforts to keep
Licensed Products and/or Licensed Processes  reasonably available to the public.
In the event Licensee  decides not to practice under a licensed Patent Right, it
shall promptly inform CMCC in writing and shall surrender to CMCC its license to
that Patent Right.

         B. As part of its Due Diligence,  Licensee shall cause the formation of
NewCo within three (3) months of the  Effective  Date of this  Agreement,  shall

Licensed Products and Licensed  Processes,  including to the extent practicable:
(i)  time-delimited  targets  for  pre-clinical  development,  clinical  trials,
regulatory  approval,  manufacturing  and marketing  that  represent  reasonable
efforts, consistent with industry norms for similar technology and applications,
to bring Licensed Products and Licensed  Processes to the marketplace;  and (ii)
actual or projected  financial resources and/or strategic alliances that will be
required to  implement  the  Development  Plan.  The  Development  Plan shall be

milestones set forth in the  Development  Plan and to manufacture and distribute
Licensed Products and Licensed Processes.

         E.  Notwithstanding  anything  above to the  contrary,  CMCC  shall not
unreasonably  withhold its assent to any revision of the  objective(s) set forth
in the  Development  Plan when requested in writing by Licensee and supported by
evidence reasonably acceptable to CMCC: (i) of technical  difficulties or delays
in the  clinical  studies or  regulatory  process that  Licensee  could not have
reasonably  avoided;  or (ii) that Licensee,  its Affiliates and/or sublicensees
have  expended  good faith and diligent  efforts and adequate  resources to meet
said objective.

         F.  In  the  event  CMCC  reasonably  believes  that  Licensee  is  not
diligently  seeking to achieve the objectives set forth in the Development  Plan
in a timely  manner,  CMCC shall so notify  Licensee in writing.  Licensee shall
have the option,  exercisable by written notice to CMCC provided within ten (10)
days after receipt of any such notice, to either:  (i) receive a three (3) month
grace period to establish to CMCC's  reasonable  satisfaction  that  Licensee is
expending its good faith and diligent efforts and adequate  resources to achieve
said  objectives;  or (ii)  agree to CMCC's  termination  of this  Agreement  as
provided  hereinafter.  In the  event  Licensee  agrees to  termination  of this
Agreement, CMCC shall immediately terminate the license granted to License under
this Agreement. In the event Licensee fails to establish its diligence to CMCC's
reasonable  satisfaction  as provided above prior to expiration of the three (3)
month grace period,  CMCC shall have the right to terminate the license  granted
to Licensee under this  Agreement or to convert the license  granted to Licensee
hereunder to a non-exclusive  license on financial terms and conditions mutually
agreed to by CMCC and Licensee.

         G. In the event  Licensee fails to meet the  objective(s)  set forth in
the Development  Plan in a timely manner,  CMCC shall notify Licensee thereof in
writing, and Licensee shall have thirty (30) days following such notification to
establish  to the  reasonable  satisfaction  of CMCC  that  (i) it has met  such
objective(s);  or (ii) a  revision  to the  Development  Plan is  necessary  and
appropriate as contemplated  above. In the event Licensee fails to establish the
same to CMCC's reasonable satisfaction,

                                       -7-

CMCC shall have the right in its discretion to terminate the license  granted to
Licensee  under this  Agreement  or to convert the  license  granted to Licensee

                Partnership                                          REQUESTED]


         Notwithstanding  the  foregoing,  if Licensee has provided  funding for
sponsored  research to be conducted in Dr.  Stuart  Lipton's  laboratory,  up to
[CONFIDENTIAL  TREATMENT  REQUESTED]  of such  funding for work to be  conducted
during the period  beginning  September 1, 1995 and ending December 31, 1996 may
be credited  against  payment of Milestone (ii) above,  and up to  [CONFIDENTIAL
TREATMENT  REQUESTED] of such funding for work to be conducted during the period
beginning  January 1, 1997 and ending December 31, 1997 may be credited  against
payment of Milestone (iii) above.

                  4.  Licensee   shall  pay  CMCC  a   [CONFIDENTIAL   TREATMENT
         REQUESTED]  royalty  on Net  Sales of  Licensed  Products  or  Licensed
         Processes  used,  leased  or sold by and/or  for  Licensee  and/or  its
         Affiliates, provided that

                           (a) The royalty rate will be reduced by [CONFIDENTIAL
                  TREATMENT REQUESTED] during any period in any country in which
                  Licensee  can  demonstrate  there  is  significant  unlicensed
                  competition in sales in the Field of Use (i.e.,  [CONFIDENTIAL
                  TREATMENT  REQUESTED]  or more of sales in the Field of Use of
                  products or processes  that infringe upon the Patent Rights by
                  third parties other than the Ophthalmologic Licensee), and

                           (b) The license  issuance fees paid by Licensee under
                  Paragraph 1 of this  Section IV.A and the  milestone  payments
                  paid by Licensee under Paragraph 3 of this Section IV.A may be
                  credited

                                       -9-
<PAGE>

                  against  royalty  payments  up  to a  limit  of  [CONFIDENTIAL
                  TREATMENT  REQUESTED]  of the royalty  due in a given  payment
                  period.

                  5. In the event  Licensee has granted  sublicenses  under this
         Agreement,  [CONFIDENTIAL  TREATMENT REQUESTED] of any and all payments
         received  by  Licensee  from  said  sublicensees  in  consideration  of
         permitting the sublicensee to practice the Patent Rights, including but
         not limited to sublicense issue fees, any lump sum payments,  milestone
         payments,  technology  transfer  payments or other  similar  fees,  and
         royalties,  but not including any payments designated and actually used
         for research,  development or commercialization of Licensed Products or
         Licensed Processes;  provided that with respect to running royalties in
         connection with a sublicensee's  sales of Licensed Products or Licensed
         Processes, if the product is covered by a composition of matter patent,
         Licensee  shall pay to CMCC  hereunder  an amount  equal to the royalty
         CMCC would have  received  from Licensee if such sales had been made by
         Licensee.

         B. No multiple  royalties shall be payable because any Licensed Product
or Licensed Process, 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.

         C. To the extent that Licensee  obtains  subsequent to the date of this
Agreement  licenses to third party patents or other  intellectual  property that
are  necessary  to produce or sell  Licensed  Products  or  Licensed  Processes,
Licensee  may  deduct  from  the  royalty  due to CMCC  [CONFIDENTIAL  TREATMENT
REQUESTED]  of the  royalties  due on such third party  patents or  intellectual
property  up to  an  amount  equal  to  [CONFIDENTIAL  TREATMENT  REQUESTED]  of
royalties hereunder.

         D. For purposes of calculating royalties,  in the event that a Licensed
Product or Licensed Process includes both component(s)  covered by a valid claim
of a Patent Right ("Patented Component") and a component which is diagnostically
usable  or  therapeutically  active  alone or in a  combination  which  does not
require the  Patented  Component,  and such  component is not covered by a valid
claim  of a  Patent  Right  ("Unpatented  Component"),  then  Net  Sales  of the
Combination  Product or Combination Process shall be calculated using one of the
following  methods;  provided that in no event shall  royalties  payable to CMCC
hereunder by reduced to less than  [CONFIDENTIAL  TREATMENT  REQUESTED] of those
otherwise due hereunder:

                  1. By multiplying the Net Sales of the Combination  Product or
         Combination  Process during the applicable  royalty  accounting  period
         ("accounting  period") by a  fraction,  the  numerator  of which is the
         aggregate gross selling price of the Patented Component(s) contained

                                      -10-
<PAGE>

         in the Combination  Product or Combination  Process if sold separately,
         and the  denominator  of which is the sum of the gross selling price of
         both  the  Patented   Component(s)  and  the  Unpatented   Component(s)
         contained in the  Combination  Product or  Combination  Process if sold
         separately; or

                  2. In the event  that no such  separate  sales are made of the
         Patented   Component(s)  or  the  Unpatented   Components   during  the
         applicable  accounting  period,  Net Sales for purposes of  determining
         royalties  payable hereunder shall be calculated by multiplying the Net
         Sales of the Combination  Product or Combination Process by a fraction,
         the numerator of which is the fully  allocated  production  cost of the
         Patented  Component(s)  and the  denominator of which is the sum of the
         fully allocated  production costs of the Patented  Component(s) and the
         Unpatented   Component(s)  contained  in  the  Combination  Product  or
         Combination Process.  Such fully allocated costs shall be determined by
         using Licensee's standard accounting procedures,  which procedures must
         conform to standard cost accounting procedures.

         E. Royalty  payments  shall be paid in United States dollars in Boston,
Massachusetts,  or  at  such  other  place  as  CMCC  may  reasonably  designate
consistent with the laws and regulations  controlling in any foreign country. If
the currency  conversion  shall be required in  connection  with the payments of
royalties or other amounts hereunder,  the conversion shall be made by using the
exchange  rate  prevailing at the Bank of Boston on the last business day of the
calendar quarterly reporting period to which such royalty payments relate.

         F. The royalty  payments set forth in this Agreement shall, if overdue,
bear  interest  until payment at a per annum rate of four percent (4%) above the
prime rate in effect at the Bank of Boston on the due date.  The payment of such
interest shall not foreclose  CMCC from  exercising any other rights it may have
as a consequence of the lateness of any payment.

                         ARTICLE V. REPORTS AND RECORDS

         A.  Licensee   shall  keep,   and  shall  require  its  Affiliates  and
sublicensees  to keep,  full,  true and accurate  books of account in accordance
with generally accepted accounting  principles and containing  sufficient detail
to enable CMCC to determine the royalty and other amounts  payable to CMCC under
this  Agreement.  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 retained for at least five (5) years  following the end of the calendar
year to which they pertain.

         B. CMCC shall  have the right to audit the books of  account  described
above from time to time to the extent  necessary to verify the reports  provided
for

                                      -11-
<PAGE>

herein or compliance in other respects with this  Agreement.  CMCC or its agents
shall perform these audits at CMCC's expense during Licensee's  regular business
hours.

         C. Licensee  shall  deliver to CMCC true and accurate  reports by March
31, for the period  July 1 through  December  31 of the  previous  year,  and on
September  30, for the period  January 1 through  June 30 of the  current  year,
giving such  particulars of the business  conducted by Licensee,  its Affiliates
and its  sublicensees  under this  Agreement  as shall be pertinent to a royalty
accounting  hereunder  and to  verify  Licensee's  activities  with  respect  to
achieving the objectives of the Development Plan described in Article III above.
These reports shall include at least the following:

                  1.       Number of Licensed Products and Licensed Processes
         manufactured and sold.

                  2.       Aggregate billings for Licensed Products and Licensed
         Processes sold.

                  3.       Accounting for all Licensed Products and Licensed
         Processes sold.

                  4.       Applicable deductions.

                  5.       Total royalties due.

                  6.       Names and addresses of all sublicensees of Licensee.

                  7.       Payments  received by Licensee  from  Affiliates  and
                           sublicensees.

                  8.       Royalties and Fees received from sublicensees.

                  9.       Licensed Products  manufactured  and sold to the U.S.
         Government.  No royalty  obligations  shall arise from sales or use by,
         for or on behalf  of the U.S.  Government  in view of a  royalty  free,
         nonexclusive  license that may heretofore have been granted to the U.S.
         Government.

         D. Until the First  Commercial  Sale of a Licensed  Product or Licensed
Process,  Licensee  shall provide to CMCC at least  annually  reasonable  detail
regarding the activities of Licensee and Licensee's  Affiliates and sublicensees
relative to achieving  the  objectives  set forth in the  Development  Plan in a
timely manner,  including but not limited to, reports of financial  expenditures
to achieve said  objectives,  research and  development  activities,  regulatory
approvals,  strategic  alliances and  manufacturing,  sublicensing and marketing
efforts.

                                      -12-

<PAGE>

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

         F. On or  before  the  ninetieth  (90th)  day  following  the  close of
Licensee's  fiscal year,  Licensee shall provide CMCC with Licensee's  certified
financial  statements  for the preceding  fiscal year,  including at a minimum a
balance sheet and an operating statement.

                         ARTICLE VI. PATENT PROSECUTION

         A. CMCC shall apply for, seek prompt  issuance of, and maintain  during
the term of this  Agreement  the  Patent  Rights  set forth in  Appendix  1. The
prosecution,  filing and  maintenance  of all  Patent  Rights  applications  and
patents  shall be the  primary  responsibility  of  CMCC.  Licensee  shall  have
reasonable  opportunities  to advise CMCC and shall  cooperate  with CMCC in the
prosecution, filing and maintenance of the Patent Rights.

         B.  Licensee  shall  reimburse to CMCC the amount of all fees and costs
relating  to the  filing,  prosecution  and  maintenance  of the  Patent  Rights
incurred  after the date of this  Agreement  unless any of those Rights are also
licensed  to a third  party in a field of use other  than the  Field of Use,  in
which case,  Licensee shall reimburse CMCC for half of the costs relating to the
filing,  prosecution and maintenance of those Patent Rights that are so licensed
to said third party.  CMCC shall provide to Licensee an itemized  invoice of all
such fees and  Licensee  shall pay to CMCC all  amounts  due under said  invoice
within ten (10) days of the date of said invoice.

         C. In the  event  CMCC  elects  not to  pursue,  maintain  or  retain a
particular  Patent Right  licensed to Licensee  hereunder,  CMCC shall so notify
Licensee in  sufficient  time for  Licensee  to assume the  filing,  prosecution
and/or maintenance of such application or patent at Licensee's  expense. In such
event,  CMCC shall  provide to Licensee  any  authorization  necessary to permit
Licensee to pursue and/or  maintain such Patent  Right.  Licensee  shall have no
further royalty obligations under this Agreement with respect to any such Patent
Right.

                            ARTICLE VII. INFRINGEMENT

         A. Licensee and CMCC shall each inform the other promptly in writing of
any alleged  infringement  by a third party of the Patent Rights in the Field of
Use and of any available evidence thereof.

         B. During the term of this  Agreement,  CMCC shall have the right,  but
shall not be obligated,  to prosecute at its own expense any infringement of the
Patent Rights and, in  furtherance  of such right,  Licensee  hereby agrees that
CMCC may include Licensee as a party plaintiff in any such suit, without expense
to Licensee.

                                      -13-

<PAGE>

The total cost of any such  infringement  action commenced or defended solely by
CMCC shall be borne by CMCC.  CMCC shall keep any  recovery  or damages for past
infringement derived therefrom.

         C. If within six (6) months after  having been  notified of any alleged
infringement,  CMCC shall  have been  unsuccessful  in  persuading  the  alleged
infringer  to  desist  and shall not have  brought  and shall not be  diligently
prosecuting an infringement action, or if CMCC shall notify Licensee at any time
prior thereto of its  intention not to bring suit against any alleged  infringer
then, and in those events only,  Licensee shall have the right, but shall not be
obligated,  to  prosecute  at its own  expense  any  infringement  of the Patent
Rights,  and  Licensee  may,  for such  purposes,  use the name of CMCC as party
plaintiff;  provided,  however,  that such right to bring  such an  infringement
action shall remain in effect only for so long as the license granted  hereunder
remains  exclusive.  No settlement,  consent  judgment or other  voluntary final
disposition  of the suit may be entered into without the consent of CMCC,  which
consent  shall not be  unreasonably  withheld.  Licensee  shall  indemnify  CMCC
against any order for costs that may be made against CMCC in such proceedings.

         D. In the event Licensee shall undertake the enforcement and/or defense
of the Patent  Rights by  litigation,  Licensee may withhold up to fifty percent
(50%) of the payments  otherwise  thereafter  due to CMCC under Article IV above
and  apply  the  same  toward  reimbursement  of up to  fifty  percent  (50%) of
Licensee's  expenses,   including  reasonable  attorney's  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 CMCC for any
payments  under  Article IV past due or withheld  and  applied  pursuant to this
Article  VII.  The balance  remaining  from any such  recovery  shall be divided
equally between Licensee and CMCC.

         E. In the event that a declaratory  judgment action alleging invalidity
or  noninfringement  of  any of the  Patent  Rights  shall  be  brought  against
Licensee,  CMCC,  at its option,  shall have the right,  within thirty (30) days
after  commencement of such action,  to intervene and participate in the defense
of the action at its own expense.

         F. In any infringement suit which either party may institute to enforce
the Patent Rights pursuant to this  Agreement,  the other party hereto shall, at
the request and the expense of the party initiating such suit,  cooperate in all
reasonable respects and, to the extent reasonably  possible,  have its employees
testify when requested and make available relevant records, papers, information,
samples, specimens, and the like.

         G. Licensee  shall during the exclusive  period of this  Agreement have
the sole right  subject to the terms and  conditions  hereof to  sublicense  any
alleged infringer for future use of the Patent Rights.  Any upfront fees paid to
Licensee as

                                      -14-
<PAGE>
part of such a sublicense shall be shared equally between Licensee and CMCC. Any
other royalties shall be treated as set forth in Article IV, Paragraph 5.

             ARTICLE VIII. INDEMNIFICATION AND INSURANCE PROVISIONS

         A. Licensee shall indemnify, defend and hold harmless CMCC and HARVARD,
its  corporate  affiliates,  current or future  directors,  trustees,  officers,
faculty,  medical and  professional  staff,  employees,  students and agents and
their respective successors, heirs and assigns (the "Indemnitees"),  against any
liability,  damage,  loss or expense (including  reasonable  attorney's fees and
expenses of litigation)  incurred by or imposed upon the  Indemnitees or any one
of them in  connection  with any claims,  suits,  actions,  demands or judgments
arising out of any theory of product liability  (including,  but not limited to,
actions  in the form of tort,  warranty,  or strict  liability)  concerning  any
product,  process or service made, used or sold pursuant to any right or license
granted under this Agreement.

         B.  Licensee's  indemnification  under Article VIII,  Paragraph A above
shall not apply to any liability,  damage, loss or expense to the extent that it
is directly  attributable to the negligent  activities,  reckless  misconduct or
intentional misconduct of the Indemnitees.

         C. Licensee agrees, at its own expense, to provide attorneys reasonably
acceptable  to CMCC to defend  against any actions  brought or filed against any
party indemnified  hereunder with respect to the subject of indemnity  contained
herein, whether or not such actions are rightfully brought.

         D. Article  VIII,  Paragraphs A through C shall  survive  expiration or
termination of this Agreement.

         E.  Beginning  at the time as any such  product,  process or service is
being commercially  distributed or sold (other than for the purpose of obtaining
regulatory  approvals)  by Licensee or by a  sublicensee,  Affiliate or agent of
Licensee,  Licensee  shall,  at its sole cost and expense,  procure and maintain
commercial  general liability  insurance in amounts not less than $2,000,000 per
incident  and  $2,000,000   annual  aggregate  and  naming  the  Indemnitees  as
additional  insureds.  Such commercial general liability insurance shall provide
(i) product  liability  coverage  and (ii)  contractual  liability  coverage for
Licensee's  indemnification  under Article VIII,  Paragraphs A through C of this
Agreement. If Licensee elects to self-insure all or part of the limits described
above  (including  deductibles  or  retentions  which are in excess of  $250,000
annual aggregate),  such  self-insurance  program must be acceptable to CMCC and
the Risk  Management  Foundation of the Harvard Medical  Institutions,  Inc. The
minimum amount of insurance coverage required under this Article VIII, Paragraph
E. shall not be construed to create a limit of Licensee's liability with respect
to its  indemnification  under  Article  VIII,  Paragraphs  A  through C of this
Agreement.


                                      -15-
<PAGE>

         F. Licensee shall provide CMCC with written  evidence of such insurance
upon request of CMCC.  Licensee  shall provide CMCC with written notice at least
fifteen (15) days prior to the  cancellation,  non-renewal or material change in
such  insurance.  If Licensee does not obtain  replacement  insurance  providing
comparable  coverage  within such fifteen  (15) day period,  CMCC shall have the
right to terminate this Agreement  effective at the end of such fifteen (15) day
period without notice of any additional waiting periods.

         G. Licensee shall maintain such commercial general liability  insurance
during  (i) the  period  that any such  product,  process  or  service  is being
commercially  distributed  or sold  (other  than for the  purpose  of  obtaining
regulatory  approvals)  by Licensee or by a  sublicensee,  Affiliate or agent of
Licensee and (ii) a reasonable period after the period referred to above,  which
in no event shall be less than fifteen (15) years.

         H. Article  VIII,  Paragraphs E through G shall  survive  expiration or
termination of this Agreement.

         I. OTHER THAN  WARRANTIES  SET FORTH  HEREIN,  CMCC MAKES NO  WARRANTY,
EXPRESS OR IMPLIED,  INCLUDING,  WITHOUT  LIMITATION,  ANY  IMPLIED  WARRANTY OF
MERCHANTABILITY OR ANY IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE WITH
RESPECT TO ANY PATENT,  TRADEMARK,  SOFTWARE,  TRADE SECRET,  TANGIBLE  RESEARCH
PROPERTY,  INFORMATION  OR DATA  LICENSED  OR  OTHERWISE  PROVIDED  TO  LICENSEE
HEREUNDER AND HEREBY DISCLAIMS THE SAME.

         J. Licensee  shall  indemnify  defend and hold  harmless  [CONFIDENTIAL
TREATMENT  REQUESTED]  and their  respective  corporate  affiliates,  current or
future directors,  trustees,  officers, faculty, medical and professional staff,
employees,  students  and  agents  and their  respective  successors,  heirs and
assigns   (collectively,   the   "[CONFIDENTIAL   TREATMENT   REQUESTED]-related
Indemnitees") against any claims, liability,  damage, loss or expense (including
reasonable  attorney's  fees and expenses of litigation)  incurred by or imposed
upon the [CONFIDENTIAL  TREATMENT  REQUESTED]-Related  Indemnitees or any one of
them in connection with any claims, suits,  actions,  demands or judgments which
may ever accrue to [CONFIDENTIAL TREATMENT REQUESTED] or their respective heirs,
executors, legal representatives, successors or assigns in any way pertaining to
or arising out of [CONFIDENTIAL  TREATMENT REQUESTED] activities with respect to
memantine or the ACTG Trial or any  dealings  with the  [CONFIDENTIAL  TREATMENT
REQUESTED]-related Indemnitees.

                           ARTICLE IX. EXPORT CONTROLS

         It is  understood  that  CMCC is  subject  to  United  States  laws and
regulations  controlling  the  export  of  technical  data,  computer  software,
laboratory  prototypes and other commodities  (including the Arms Export Control
Act, as amended and the

                                      -16-
<PAGE>

Export  Administration  Act of 1979),  and that its  obligations  hereunder  are
contingent  on  compliance  with  applicable   United  States  export  laws  and
regulations.  The transfer of certain technical data and commodities may require
a license  from the  cognizant  agency of the United  States  Government  and/or
written   assurances  by  Licensee  that  Licensee  shall  not  export  data  or
commodities to certain foreign  countries without prior approval of such agency.
CMCC  neither  represents  that a  license  shall not be  required,  nor that if
required, it shall be issued.

                           ARTICLE X. NON-USE OF NAMES

         Licensee   shall  not  use  the  name  of  Children's   Medical  Center
Corporation  or  HARVARD  nor the  name  of any of  their  respective  corporate
affiliates  or  employees,  nor  any  adaptation  thereof,  in any  advertising,
promotional or sales literature without prior written consent obtained from CMCC
in each case,  except that  Licensee may state that it is licensed by CMCC under
one or more of the patents and/or applications comprising the Patent Rights, and
Licensee may comply with disclosure requirements of all applicable laws relating
to its business, including United States and state security laws.

                             ARTICLE XI. ASSIGNMENT

         A.  Except  as  otherwise  provided  herein,   this  Agreement  is  not
assignable in whole or in part, and any attempt to do so shall be void and of no
force and effect.

         B.  CMCC  may  assign  this  Agreement  at any  time  to any  corporate
affiliate of CMCC without the prior consent of Licensee.

         C. Except as provided in Article XI, Paragraph D and Paragraph E below,
Licensee may assign this Agreement to another entity only with the prior written
consent of CMCC, which consent shall not be unreasonably withheld or delayed.

         D.  Notwithstanding  anything  herein  to the  contrary,  in the  event
Licensee merges with another entity, is acquired by another entity, or sells all
or  substantially  all of its assets to another entity,  Licensee may assign its
rights and  obligations  hereunder to, in the event of a merger or  acquisition,
the surviving entity, and in the event of a sale, the acquiring entity,  without
CMCC's consent so long as: (i) Licensee is not then in breach of this Agreement;
(ii) the proposed  assignee has a net worth at least equivalent to the net worth
Licensee had as of the date of this Agreement;  (iii) the proposed  assignee has
available  resources and  sufficient  scientific,  business and other  expertise
comparable  to  Licensee  in order to satisfy its  obligations  hereunder;  (iv)
Licensee  provides  written  notice of the  assignment  to CMCC,  together  with
documentation   sufficient  to  demonstrate  the   requirements   set  forth  in

respective field of use.  Licensee has requested that CMCC provide Licensee with
the name, address,  and description of the field of use of CMCC's Other Licensee

         C. It is expressly  agreed by the parties hereto that CMCC and Licensee
are independent  contractors and nothing in this Agreement is intended to create

with  respect  to the  subject  matter  hereof  and  supersedes  all  proposals,
negotiations and other  communications  between the parties,  whether written or
oral, with respect to the subject matter hereof.

         E. If any  provisions  of this  Agreement  shall be held to be invalid,
illegal or  unenforceable,  the  validity,  legality and  enforceability  of the
remaining provisions of this Agreement shall not be impaired thereby.

                                   APPENDIX 3

                      INTERACTION AND COMMUNICATION BETWEEN
                       LICENSEE AND CMCC'S OTHER LICENSEE

         A.  Licensee  agrees to  establish a  Scientific  Management  Committee
(hereinafter  "SMC") to allow  Licensee and CMCC's Other Licensee to communicate
with one another  and/or  receive  information  from one another  concerning the
commercial  development  of the  Patent  Rights.  The SMC shall  consist of four
members,  two appointed by Licensee and two appointed by CMCC's Other  Licensee.
The   Chairperson   of  the  SMC  shall  be  appointed   alternately   from  the
representatives of each licensee and shall hold position for one year.  Licensee
shall  appoint the first  Chairperson.  CMCC and the  Massachusetts  Eye and Ear
Infirmary shall each have the right to select a representative to participate in
the SMC as an  observer.  In  addition,  Dr.  Stuart  Lipton  will  be  provided
opportunities  to be engaged by Licensee as  consultants,  as  appropriate,  for
their expertise,  advise,  and counsel.  The SMC will meet as soon as reasonably
possible following the execution of this Agreement and notification by CMCC that
CMCC has entered into a definitive agreement with CMCC's Other Licensee. The SMC
shall meet,  thereafter,  at six (6) month  intervals,  or as  otherwise  agreed
between  Licensee and CMCC's Other Licensee to communicate  progress on research
activities  and to review and  recommend  possible  research  projects for joint
sponsorship  and  funding.   Minutes  of  these  meetings  shall  be  taken  and
distributed  to Licensee,  CMCC, and CMCC's Other Licensee as a formal record of
the proceedings and actions, if any.

         B.  All data and  information  generated  by  Licensee's  research  and
development  activities  with  respect to the  Patent  Rights  shall  remain the
exclusive property of Licensee and all data and information  generated by CMCC's
Other Licensee's research and development  activities with respect to the Patent
Rights shall remain the  exclusive  property of CMCC's Other  Licensee.  Neither
Licensee nor CMCC's Other  Licensee shall have the right to use the other's data
and information  for any purpose  without written  permission from the other. To
the extent that the licensees  agree to cosponsor and co-fund  certain  research
activities  during their  development of the Patent  Rights,  both parties shall
jointly own the resulting data and  information and shall both have the right to
use the data and  information as they see fit.  Notwithstanding  the above,  the
licensees  shall  communicate  to one  another how they intend to use such joint
data and information  through the SMC and the SMC shall  coordinate the use, and
the timing of the use, of such joint data and  information  by both licensees to
ensure that neither licensee is unfairly disadvantaged by such use.

         C.  Licensee  and CMCC  acknowledge  that  Licensee  and  CMCC's  Other
Licensee may  develop,  market and sell the same dosage form and strength of the
same compound for different indications.  It is CMCC's intent that each licensee
focus only on its licensed field of use.  However,  if significant  Net Sales of
one  licensee  can be shown to have been made for  indications  within the other
licensee's  field of use,  a rebate to  compensate  the other  licensee  will be
provided by the

                                      -25-

<PAGE>

licensee  receiving the profits from said sales in the other licensee's field of
use. Such a rebate,  if any, shall be determined based upon the Net Sales booked
by each  licensee and the percent of  prescriptions  attributed  to  indications
and/or  the  appropriate  prescribers  within  the  licensee's  field  of use as
measured by NDTI,  PDDA, or other agreed upon  prescription  audit.  Such rebate
shall be equal to the profit the other  licensee  would have  received if it had
made the sale in its field of use but  shall  not  exceed  the  profit  actually
realized by the licensee making the sale.

         D. CMCC will  grant or cause  CMCC's  Other  Licensee  to grant a first
right of refusal to  Licensee  to obtain an  exclusive  royalty-bearing  license
outside CMCC's Other  Licensee's  field of use to make, have made, use, and sell
any  pharmaceutical   composition  covered  under  the  Patent  Rights  that  is
discovered by CMCC's other licensee during the term of this Agreement.

         E. Licensee agrees CMCC will grant or Licensee will grant a first right
of refusal  to CMCC's  Other  Licensee  to obtain an  exclusive  royalty-bearing
license within CMCC's Other Licensee's field of use to make, have made, use, and
sell any  pharmaceutical  composition  covered  under the Patent  Rights that is
discovered by Licensee during the term of this agreement.

         F. The  provisions  of this  Appendix  3 may be  changed  only with the
mutual  consent of Licensee,  CMCC's Other  Licensee,  and CMCC.  CMCC shall not
unreasonably  withhold or delay  consent to any change agreed to by Licensee and
CMCC's Other Licensee.

                  beginning  September 1, 1995 and ending  December 31, 1996 may

                  [CONFIDENTIAL   TREATMENT  REQUESTED]  of  such  consideration
                  provided during the period January 1, 1997 and ending December

                  previous period,  may be credited against payment of Milestone

                  Licensee  as lease  payments  for  equipment  provided  to the
                  laboratory or the value of equipment actually purchased
