                                     PART I

ITEM 1.           BUSINESS.

GENERAL

         Gliatech is engaged in the discovery and development of biosurgical and
therapeutic products to improve surgical outcomes and to treat neurological
disorders. The biosurgical products include the ADCON family of products and a
proprietary monoclonal antibody to block the inappropriate activation of the
complement pathway. The ADCON family of products consist of proprietary,
resorbable, carbohydrate polymer medical devices designed to inhibit scarring
and adhesions following surgery. The proprietary monoclonal antibody is designed
to block the inappropriate activation of the complement pathway and inhibit
inflammation associated with a variety of indications such as coronary bypass
surgery, heart attack and stroke. In addition to the biosurgical products, the
Company is pursuing the development of small molecule drug candidates for the
treatment of several neurological disorders, including Attention Deficit
Hyperactive Disorder ("ADHD"), sleep disorders, anxiety, schizophrenia and
Alzheimer's Disease ("AD"). The discussion presented below should be read in
conjunction with the Company's consolidated financial statements and related
notes appearing elsewhere in this Annual Report on Form 10-K.

BIOSURGERY

         ADCON FAMILY OF PRODUCTS

         ADCON-L

         ADCON-L is a proprietary, resorbable, carbohydrate polymer gel, which
is applied directly to the surgical site during lumbar surgery. ADCON-L is
designed to provide a physical barrier between the membranes covering the spinal
cord and the back muscles, and between the spinal nerve roots and the inner
surface of the vertebral body. This physical barrier inhibits excess scarring
and adhesions at the surgical site and improves surgical outcomes. Because it is
not possible to predict prior to surgery which patients are likely to develop
adhesion-related problems, ADCON-L is designed to be used prophylactically as a
physical barrier between tissues to inhibit scarring and adhesions in all
patients undergoing lumbar surgeries.

         Clinical Results. To date, the Company has conducted clinical trials in
the United States and in Europe. These studies demonstrated that ADCON-L
inhibits peridural scar and improves surgical outcomes by reducing activity
related pain. In addition, in August 1999, the Company filed an Investigational
Device Exemption ("IDE") with the Food and Drug Administration ("FDA") to
initiate a pilot clinical trial evaluating ADCON-L following breast augmentation
surgeries. This pilot clinical trial will evaluate ADCON-L at two clinical study
sites. Patient enrollment in this pilot clinical trial was completed in the
first quarter of 2000 and the Company is currently collecting and evaluating
data from the trial.

         ADCON-P

         ADCON-P is a proprietary, resorbable, carbohydrate polymer liquid,
which is applied directly into the peritoneal cavity during pelvic and
gynecologic surgeries, such as reoperations to remove adhesions and uterine
tumor surgeries. ADCON-P is designed to provide a physical barrier to inhibit
scarring and adhesions, which may bind the uterus, fallopian tubes or ovaries to
the surrounding pelvic cavity and cause infertility or pain.

         Development and Regulatory Status. After completing a pilot clinical
trial for ADCON-P in the United States, the Company received approval, in
November 1998, from the FDA to initiate a pivotal clinical trial for ADCON-P in
the United States. The Company commenced patient enrollment of its pivotal
clinical trial in January 1999. Patient enrollment for the Company's ADCON-P
pivotal clinical trial is expected to be completed in the second quarter of
2000. During the pivotal trial, ADCON-P will be evaluated at approximately 20
clinical study sites in over 200 patients undergoing minimally invasive
gynecological surgery.

         In addition, in February 2000, the Company requested that ADCON-P be
reviewed under the FDA's "modular review" program to initiate the Premarket
Approval Application ("PMA") process. To date, the Company has submitted the
modular PMA shell, which is an outline of the PMA for ADCON-P, to the FDA. The
FDA's modular review program permits companies to submit to the FDA sections of
the PMA in stages, allowing the FDA to begin its review process as the modules
are submitted. The modules the Company proposes to submit are administrative,
preclinical, manufacturing and clinical. The proposed modules are in various
stages of preparation and the


                                        2

<PAGE>   4



Company expects to submit such modules during 2000. The PMA will be considered
filed when the clinical data section and any remaining information is submitted
and accepted by the FDA.

         ADCON-A

         ADCON-A is a proprietary, resorbable, carbohydrate polymer liquid,
which is applied directly into the upper peritoneal cavity following certain
abdominal and colorectal surgeries. ADCON-A is designed to inhibit scarring and
adhesions, which can lead to, among other things, small bowel obstruction and
chronic pain in the abdominal area.

         Development and Regulatory Status. In May 1999, the Company received
approval from the FDA to initiate a pilot clinical trial for ADCON-A. ADCON-A
and ADCON-P are identical products, but FDA regulations require that each be
evaluated separately for each intended clinical indication. The Company has
completed enrollment of its pilot clinical trial for ADCON-A and expects to
submit the results of this study and an IDE to the FDA in the third quarter of
2000 to seek approval to begin a pivotal clinical study.

         ADCON-T/N

         ADCON-T/N is a proprietary, resorbable, carbohydrate polymer gel, which
is applied directly to the surgical site following tendon and peripheral nerve
surgeries, such as primary tendon repair and reoperations to remove adhesions on
tendons or peripheral nerves. ADCON-T/N is designed to act as a physical barrier
between the peripheral nerve or tendon and the surrounding tissue.

         Clinical Results. In November 1995, the Company completed open label
clinical trials in Europe to evaluate the use of ADCON-T/N in inhibiting
scarring and adhesions following various surgical procedures involving tendons
and nerves.

         Early in 1995, the Company received approval from the FDA to initiate
two clinical trials. However, in order to focus its resources and efforts on the
acceleration of other ADCON clinical studies and on the continued progress of
its other preclinical and research programs, the Company closed patient
enrollment. This decision was made primarily because of the length of time and
difficulty in enrolling patients under the current protocol. Available data
gathered to date was submitted and reviewed with the FDA, but the number of
patients in the study were deemed by the FDA to be insufficient. The Company
will evaluate other alternatives to address the tendon and peripheral nerve
market in the United States.

         OTHER ADCON PRODUCTS

         The Company is also developing certain additional proprietary,
resorbable, carbohydrate polymer medical devices and is currently conducting
preclinical studies relating to applications of such ADCON technology in
inhibiting scarring and adhesions in certain other surgical procedures. Due to
the differences in the body environments in which each of the products would be
used, the Company's ADCON products are being designed to be adapted for use at
the specific surgical site. The additional devices include ADCON-I for use in
implant/prosthetic surgery and ADCON-C for use in cardiac surgery.

         MONOCLONAL ANTIBODIES

         PROPERDIN

         The Company has developed a proprietary monoclonal antibody to the
complement protein properdin, which blocks the inappropriate activation of the
complement pathway. Inappropriate activation of this pathway can lead to
unwanted cellular inflammation associated with several acute inflammatory
disorders, including coronary bypass surgery, heart attack and stroke. This
monoclonal antibody has been effective in preclinical models in inhibiting the
activation of the complement pathway.

         In order to assist in the development of this monoclonal antibody for
human clinical trials, the Company signed, in December 1999, a research license
and option agreement with Abgenix, Inc. under which the Company will use
Abgenix's XenoMouse(R) technology to generate fully human monoclonal
antibodies to the complement protein properdin. These human monoclonal
antibodies are being designed for use in the fields of cardiovascular and
inflammatory diseases. In return, Abgenix will receive a technology access
payment and could receive additional


                                        3

<PAGE>   5



fees and milestone payments plus royalties on future product sales by the
Company. The Company will be responsible for product development, manufacturing
and marketing of any products developed through the collaboration.

NEUROLOGICAL DISORDERS PROGRAMS

         The Company is also engaged in the research and development of small
molecule compounds for the treatment of several neurological disorders. These
neurological disorders include ADHD, sleep disorders, anxiety, schizophrenia and
AD.

         COGNITION MODULATION - PERCEPTIN

         The Company has identified classes of small molecules which act on
the histamine H(3) receptor in the brain. Histamine is a chemical messenger
released from certain neurons in the brain which regulates sleep/wake states and
modulates levels of arousal and alertness in the conscious state. The histamine
H(3) receptor is predominantly found in the brain and regulates the synthesis
and release of histamine in the brain. An antagonist to this receptor would lead
to enhanced states of arousal and alertness. The histamine H(3) receptor
antagonists may be useful in treating disorders in which central nervous system
arousal is desirable, such as ADHD or narcolepsy. An agonist to the receptor may
prove useful in treating disorders in which suppression of the central nervous
system is desirable, such as anxiety and insomnia.

         Clinical Results. In February 1999, the Company completed a Phase I
double-blind human clinical trial of its H(3) receptor antagonist, Perceptin,
which was conducted at a single site in London, England. The trial involved 64
patients and was used to test the safety and tolerability profile of the H(3)
receptor antagonist. In the fourth quarter of 1999, the Company received FDA
approval to begin Phase II clinical trials of Perceptin for the treatment of
ADHD. Patient enrollment is expected to begin in the second quarter of 2000. The
potential uses for Perceptin include ADHD, dementia associated with AD and sleep
disorders, including narcolepsy.

         SCHIZOPHRENIA

         The Company initiated a product development program for schizophrenia
and dementia which involves the regulation of human glycine transporters. These
transporters modulate the levels of the neurotransmitter glycine in the central
nervous system. The Company is developing inhibitors of these glycine
transporters that would increase the levels of glycine at the glycine receptor
and may be useful in treating symptoms of schizophrenia and dementia. The
Company has identified a small molecule drug as a lead compound for this
program.

         ALZHEIMER'S DISEASE

         The human central nervous system is composed of two interrelated
networks of cells: neurons and glial cells. Neurons transfer and process
information from within and around the body. Glial cells support, protect and
repair the neurons and maintain the environment necessary for proper neuronal
activity and neurotransmitter transfer. Additionally, glial cells release
biological mediators which regulate the inflammatory and immune response
processes. AD is characterized by progressive dementia due to degeneration and
death of neuronal cells. The cause of AD is unknown and there are no proven
means of prevention or cure.

         The Company's Alzheimer's Disease Program

         Utilizing its core glial cell technology, the Company has demonstrated
that glial cells are involved in the neuronal death associated with AD. Until
May 1999, the Company was engaged in the discovery and development of compounds
to inhibit these unwanted glial cell associated events. This research, which
related to inhibitors of beta-amyloid induced inflammation, was pursued through
the Company's strategic alliance with Janssen Pharmaceutica, N.V. of Belgium, a
wholly owned subsidiary of Johnson & Johnson ("Janssen").

         Inhibitors of Beta-Amyloid Induced Inflammation. The Company discovered
that the presence of beta-amyloid plaques results in a specific metabolic
consequence in glial cells, including the release of pro-inflammatory molecules,
which has been reported to occur in the brain of patients with AD. The Company
worked with Janssen on the development of compounds that would block the effects
of beta-amyloid plaques on glial cells and thus block or reduce the release of
inflammatory agents. The Company developed a number of high throughput in vitro
assay


                                        4

<PAGE>   6



systems that were used to screen Janssen's pharmaceutical library for inhibitors
of these beta-amyloid-induced actions. As a result of the Company's efforts,
several lead compounds that block or reduce the release of inflammatory agents
were identified.

         The Janssen Alliance

         In October 1994, the Company entered into a strategic alliance with
Janssen to collaborate on the discovery and development of therapeutic models to
treat AD. In October 1998, this alliance was restructured to provide for further
research by the Company until May 1999. During such time, Janssen was required
to make payments to the Company upon the attainment of certain clinical and
developmental milestones. Janssen was responsible for all of its development
costs, including the cost associated with clinical trials and obtaining
regulatory approval. Janssen's parent, Johnson & Johnson, has worldwide
distribution rights for all products developed as a result of this
collaboration. In May 1999, Janssen ceased funding these research efforts. The
Company believes that Janssen does not intend to select a lead compound from the
identified compounds or pursue clinical trials relating to any such compound.
The Company is in discussion with Janssen to transfer development rights of
these compounds to the Company. There can be no assurance that the Company will
be successful in obtaining such development rights from Janssen or, if the
Company is successful, that such rights will be obtained on favorable terms.

MARKETING AND SALES

         In the United States

         In the United States, the Company markets ADCON-L through a network of
independent manufacturer's agents that serve the orthopaedic and neurosurgical
markets. The Company utilizes approximately 32 such independent organizations to
market ADCON-L in the United States. The sales representatives of these
organizations are trained and managed by the sales personnel of


                                        5

<PAGE>   7



the Company, including a National Sales Manager and assisting regional sales
managers. In the United States, the Company establishes the price of its
products for sale to hospitals and the independent manufacturer's agents are
reimbursed on a commissioned basis.

         After receiving FDA approval in May 1998 to market ADCON-L in the
United States,  the Company commenced sales in the United States in June 1998.
In September 1999, the FDA issued an import alert relating to ADCON-L in
connection with a warning letter issued by the FDA to the Company's contract
manufacturing firm, European Medical Contract Manufacturing B.V. ("EMCM"),
located in The Netherlands. The import ban, which caused the Company to be
unable to import ADCON-L during the last two months of 1999, was removed after
a successful re-inspection of EMCM's facility in December. At such time, EMCM
immediately resumed production of ADCON-L for distribution in the United States
and, in the first quarter of 2000, the Company resumed distribution of ADCON-L
in the United States. All back orders have now been filled and new orders are
being processed and shipped.

         Outside the United States

         In August 1995, the Company obtained regulatory clearances to affix CE
Marking for ADCON-L, which allows the Company to market ADCON-L in the 19
European countries that recognize CE Marking. The Company currently markets
ADCON-L in approximately 30 countries outside the United States through
independent medical device distributors. The Company has entered into
distribution agreements for the sale of ADCON-L in certain countries, regions
and territories, including, without limitation, Argentina, Australia, Austria,
Belgium, Canada, Cyprus, Denmark, Finland, France, Germany, Greece, Iceland,
Ireland, Italy, Korea, Latin America, Luxemburg, Mexico, The Netherlands, New
Zealand, Norway, Portugal, Puerto Rico, the Republic of South Africa, Spain,
Sweden, Switzerland and the United Kingdom (collectively, the "Distributing
Countries").

         In January 1996, the Company obtained regulatory clearance to affix CE
Marking for ADCON-T/N, which allows the Company to market ADCON-T/N in the 19
European countries that recognize CE Marking. The Company is currently marketing
its ADCON-T/N medical device in approximately 30 Distributing Countries through
independent medical device distributors.

         The Company provides ongoing technical and marketing support to its
independent medical device distributors through its Area Sales Managers and its
Marketing and Medical departments. In addition, the Company signed a development
and exclusive license agreement in December 1996 with Chugai Pharmaceutical Co.
Ltd. ("Chugai") for the sale of ADCON-L and ADCON-T/N in Japan. Chugai
subsequently filed an application requesting regulatory approval to market such
products in Japan.

         The Company's distributor agreements provide the distributors with
exclusive distribution rights in their assigned territory. The agreements
require the distributors to meet specified minimum annual purchase targets and
to provide the Company with periodic reports on their sales to hospitals. In the
event such targets are not achieved, the Company may, upon the expiration of
applicable notice periods, terminate such arrangements. The Company currently
establishes the price of its products for sale to distributors and each
distributor then sets the price for sale to hospitals. The Company's
distributors are independent third parties, not employees of the Company, and
are not under the direct control or supervision of the Company, except that they
are subject to the terms and conditions of their respective distribution
agreements.

MANUFACTURING AND SUPPLIERS

         Currently, the Company does not have any operational manufacturing
facilities and utilizes a sole third party manufacturer, EMCM, located in
Nijmegen, The Netherlands, for the manufacture of its commercial and clinical
requirements of ADCON-L, ADCON-P, ADCON-A and ADCON-T/N. The Company believes
that the manufacturer has the ability to supply sufficient products to satisfy
the Company's existing requirements worldwide and its future requirements for
ADCON products outside the United States. The Company currently purchases the
key components for ADCON-L, ADCON-P, ADCON-A and ADCON-T/N from suppliers and
provides such components to the contract manufacturer who formulates these
components into ADCON-L, ADCON-P, ADCON-A and ADCON-T/N. The contract
manufacturer is registered as a subcontractor for the manufacture of
pharmaceutical products by The Netherlands designated agency and is certified to
International Organization of Standardization ("ISO") requirements for
manufacture of such products. ISO Certification is an internationally recognized
standard of quality manufacturing. The manufacture of the Company's products is
subject to FDA Quality Standards Regulations ("QSR") or other requirements
prescribed by the appropriate regulatory agency in the country of use.

         In September 1999, the FDA issued a warning letter indicating certain
concerns with EMCM, which subsequently resulted in the FDA issuing an import
alert causing shipments of ADCON-L into the United States to be detained. After
a successful re-inspection of EMCM's facilities to verify compliance with the
issues raised in the warning letter, the detention of ADCON-L was lifted in
December 1999 and EMCM resumed shipments in the United States in January 2000.
Although the Company continues to monitor EMCM's compliance with the applicable
regulatory requirements, there can be no assurance that the Company's current
manufacturer will continue to comply with all applicable regulatory requirements
or that such manufacturer will be able to supply the Company with such products
or that the Company will be able to identify additional manufacturers of its
products on terms acceptable to the Company.

         In December 1998, the Company leased a 12,400 square foot facility in
Solon, Ohio to establish a manufacturing site for its sales of ADCON-L in the
United States. This facility will be subject to QSR requirements. After this
facility becomes operational, which is expected to occur during 2000, the
Company believes that it will have the ability at this facility to supply
sufficient products to satisfy its future requirements for the development and
commercialization of its ADCON products in the United States.

         The Company currently obtains one of the key components for its ADCON
products from a single supplier. The Company also has developed its own
proprietary process to manufacture this key component and is currently
manufacturing it on a pilot basis through a contract manufacturer according to
QSR standards. The Company intends to have this proprietary process qualified
under applicable regulatory requirements in order to have an alternate source of
supply. In addition, the Company is pursuing qualification of additional
suppliers. There can be no assurance that such proprietary process will be
qualified or alternative sources will be located or that the current supply of
raw materials will continue to be provided on terms and conditions acceptable to
the Company.

COMPETITION

         The Company competes with both biotechnology and pharmaceutical
companies in all of its product development programs. Furthermore, academic
institutions, governmental agencies, and other public and private research
organizations also continue to conduct research, seek patent protection and
establish collaborative arrangements with commercial entities for product
development and marketing. Products resulting from these activities may compete
directly with any products developed by the Company. These companies and
institutions also compete with the Company in recruiting and retaining highly
qualified scientific personnel.

         There are significant efforts by others, including many large
pharmaceutical companies and academic institutions, to develop products that
may compete with products that are developed by the Company relating to its
biosurgical products, such as the ADCON family of products and its neurological
disorder programs, such as the Cognition Modulation Perceptin program, the AD
program and its other programs. Products that may compete with the ADCON family
of products  include Intergel(R) from LifeCore Biomedical, Inc. and Seprafilm
from Genzyme Surgical Products, both of which may compete with ADCON-P, and
Hylagel-Nuro(R) from Biomatrix, which may compete with ADCON-L. The Intergel(R)
PMA was recently recommended for non-approval by an advisory panel to the FDA,
but the product could still be

approved by the FDA. Hylagel-Nuro(R) has recently initiated pivotal clinical
trials to evaluate its use in reducing peridural scar following lumbar surgery.
Development of these as well as other products may be at a more advanced stage
of development than some of the Company's products. In addition, there may be
substantial competition in the biopharmaceutical and medical industries, both
from specialized firms and from major pharmaceutical, chemical, medical device
and surgical supply companies. Many of the Company's potential competitors have
product development capabilities and financial and human resources greater than
the Company and have manufacturing, marketing, sales and distribution
capabilities that the Company does not have. Universities and other research
institutions may develop similar technologies and processes which, in some
instances, may be utilized by others to compete with the Company's products.

         The Company expects to encounter significant competition for each of
its product candidates. To compete successfully, the Company will be required to
develop and maintain scientifically advanced technology, develop proprietary
products, attract and retain highly qualified personnel, obtain patent or other
protection for its products, obtain required regulatory approvals and
manufacture and successfully market its products, either alone or through
collaboration with third parties.

GOVERNMENT REGULATION

         The manufacture and sale of the Company's products are subject to
regulation by numerous authorities, principally the FDA. The regulatory approval
process is lengthy, expensive and uncertain. Prior to commercial sale in the
United States, the Company's products under development must be approved by the
FDA. The Company may also need to seek a new, separate approval for changes to a
marketed product, such as ADCON-L. Securing FDA approvals may require the
submission of extensive clinical data and supporting information. Product
approvals can be withdrawn for failure to comply with regulatory standards or
the occurrence of unforeseen problems following initial marketing. Failure to
comply with applicable FDA regulatory requirements could result in sanctions
being imposed on the Company or the manufacturer of its products, including
warning letters, fines, injunctions, product seizure, civil penalties, failure
of the FDA to grant premarket approval, operating restrictions, prohibitions on
importation and criminal prosecution. Sales of the Company's products outside of
the United States are subject to foreign regulatory requirements that may vary
widely from country to country. The time required to obtain clearance from a
foreign country may be longer or shorter than that required by the FDA or other
such agencies, and approval requirements may differ. There can be no assurance
that the Company will be able to obtain necessary regulatory approvals on a
timely basis, if at all, for any of its products under development, or that have
been modified, and delays in receipt or failure to receive such approvals, the
loss of previously received approvals or failure to comply with existing or
future regulatory requirements could have a material adverse effect on the
Company's business, financial condition and results of operations.

         There is no certainty that the ongoing clinical studies involving
ADCON-P and ADCON-A will be completed in a timely manner or that the data and
information obtained from these studies will be sufficient to support the filing
or approval of a premarket approval application. There can be no assurance that
the Company will be able to obtain the approvals necessary to market ADCON-P or
ADCON-A or any other products under development on a timely basis, if at all.

         ADCON-L and any other products manufactured or distributed pursuant to
FDA approval are subject to pervasive and continuing regulation by the FDA,
including recordkeeping requirements and reporting of adverse patient
experience. In addition, the Federal Food, Drug, and Cosmetic Act (the "FDC
Act") requires that medical devices and drugs be manufactured in registered
establishments and in accordance with the Good Manufacturing Practices ("GMP")
requirements. Such manufacturing facilities are subject to periodic inspections
by the FDA.

         Approval Process for Medical Devices - United States. The FDC Act
requires FDA approval prior to commercialization of medical devices. Pursuant to
the FDC Act, the FDA regulates the manufacture, sale and distribution of medical
devices in the United States. Medical devices are classified into class I, II or
III on the basis of the controls deemed by the FDA to be reasonably necessary to
ensure their safety and effectiveness. Class I devices are generally subject to
general controls (e.g., labeling and adherence to QSR requirements) and class II
devices are subject to general controls, premarket clearance and special
controls (e.g., performance standards, postmarket surveillance and FDA
guidelines). Generally, class III devices are those which require premarket
approval by the FDA in addition to general controls to ensure their safety and
effectiveness (e.g., life-sustaining, life-supporting or implantable devices
which have not been found to be substantially equivalent to legally marketed
devices). The FDA regulates the Company's ADCON-L, ADCON-P, ADCON-A and
ADCON-T/N products as class III medical devices.


                                        7

<PAGE>   9



         Before a new device can be introduced into the market, the manufacturer
or distributor generally must obtain FDA clearance or approval through either a
510(k) premarket notification or a PMA application. A 510(k) clearance will be
granted if the submitted data establish that the proposed device is
"substantially equivalent" to a legally marketed class I or II medical device,
or to a preamendment class III medical device (i.e., one that was marketed
before May 28, 1976) for which the FDA has not called for premarket approvals. A
PMA must be filed if the proposed device is not substantially equivalent to a
legally marketed class I or II device or if it is a preamendment class III
device for which the FDA requires premarket approval. A PMA must be supported by
extensive data, including preclinical and clinical trial data to demonstrate the
safety and efficacy of the device. The Company's devices currently in
development will likely be subject to the PMA process.

         If human clinical trials of a device are required and the device
presents a "significant risk," the sponsor of the device is required to file an
IDE application to obtain FDA permission prior to commencing human clinical
trials. The clinical trials must be conducted under the auspices of an
institutional review board ("IRB").

         Following receipt of the PMA, if the FDA determines that the premarket
approval application is sufficiently complete to permit a substantive review,
the FDA will "file" the application. Once the submission is filed, the FDA
begins a substantive review of the PMA. The PMA process can be expensive,
uncertain and lengthy, frequently requiring several years to complete from the
date the PMA is accepted for filing. A number of devices for which premarket
approval has been sought by other companies have never been approved for
marketing. The review time may be significantly extended by the FDA, if it
requires more information or clarification of information already provided in
the submission. During the review period, an advisory committee may be convened
to review and evaluate the application and provide recommendations to the FDA as
to whether the device should be approved. In addition, the FDA will inspect the
manufacturing facility to ensure compliance with QSR requirements prior to
approval of a premarket approval application. If granted, the premarket approval
may include significant limitations on the indicated uses for which a product
may be marketed. The FDA prohibits promoting products for unapproved or
"off-label" uses.

         Modifications to a device that is the subject of an approved PMA, its
labeling, or manufacturing process may require approval by the FDA of PMA
supplements or new PMAs. Supplements to a PMA often require the submission of
the same type of information required for an initial PMA, except that the
supplement is generally limited to that information needed to support the
proposed change from the product covered by the original PMA.

         Approval Process for Drugs - United States. Before a new drug may be
commercially sold in the United States, extensive clinical trials and other
tests on the product must be conducted and the results submitted to the FDA as
part of a lengthy approval process.

         The steps required before a new drug product may be marketed in the
United States include (1) preclinical laboratory and animal tests conducted in
accordance with Good Laboratory Practices, (2) submission to the FDA of an
investigational new drug ("IND") application, which must become effective before
human clinical trials may commence, (3) well-controlled human clinical trials to
establish the safety and efficacy of the new drug product, (4) submission of a
new drug application ("NDA") to the FDA and (5) FDA approval of the NDA. The
Company's drug products are in preclinical and early Phase I development.
Approval by the FDA must be obtained for each product and for each indication to
be treated with each product. The submission of an NDA and the subsequent
marketing of approved prescription drugs also requires the payment of certain
user fees to the FDA.

         Clinical trials involving the administration of an investigational drug
product to humans typically are conducted in three phases and are subject to
specific protocols. Each protocol indicating how the clinical trial will be
conducted must be submitted for review to the FDA as part of the IND. Further,
each clinical study must be conducted under the auspices of at least one IRB and
in accordance with informed consent requirements and other FDA requirements. The
IRB considers, among other factors, ethical concerns, the adequacy of informed
consent and protection of human subjects. The IRB or the FDA may require changes
in a protocol both prior to and after commencement of a trial. There is no
assurance that the IRB or the FDA will permit a study to go forward or, once
started, to be completed. The FDA's review of a study protocol does not
necessarily mean that if the study is successful in following the terms of the
protocol it will demonstrate the drug's safety and efficacy.

         Reports of results of preclinical studies and clinical trials for
drugs, such as those likely to be developed by the Company, are submitted to the
FDA in the form of an NDA. The NDA also includes information pertaining to the
preparation of drug substances, analytical methods, drug product formulation and
details on the manufacture of finished product as well as proposed product
packaging and labeling. Submission of an NDA does not assure FDA


                                        8

<PAGE>   10



approval for marketing. The application review process generally takes one or
more years to complete, although reviews of treatments for cancer and other
severely debilitating or life-threatening diseases may be accelerated. However,
the process may take substantially longer if, among other things, the FDA has
questions or concerns about the safety and/or efficacy of a product. No
assurance exists that the Company's drug products will qualify for expedited or
accelerated review procedures.

         The product testing and approval process is likely to take a
substantial number of years and involve the expenditure of substantial
resources. The FDA also may require postmarket testing and surveillance to
monitor the use of the product. Continued compliance with regulatory
requirements is required. Upon approval, a drug only may be marketed only for
the approved indications in the approved dosage form(s) and at the approved
dosage(s).

         Other Regulation. The Company is subject to regulation by the
Occupational Safety and Health Administration and by the United States
Environmental Protection Agency under such statutes as the Toxic Substances
Control Act, the Resource Conservation and Recovery Act and other laws. Various
states and other foreign governments often have comparable health and
environmental laws.

         Foreign Regulation. The Company is subject in many countries to
regulatory requirements concerning drugs and devices and relating to human
clinical trials, marketing approvals and product testing.

         Medical devices can be marketed in the 18 countries of the European
Economic Area ("EEA") (including the 15 countries of the European Union) as well
as in Switzerland, only if these products are CE marked. CE marking attests
compliance with the requirements of the Medical Devices Directives ("MDD").

         In order to qualify for CE marking, a medical device must be in
compliance with the MDD requirements related to the performance and safety of
medical devices (the "Essential Requirements"). In addition, the Company must
obtain conformity assessment certification from a body such as a testing
laboratory or other certifying body (the "Notified Body"). The Company is using
a Dutch Notified Body for this purpose and has chosen a particular conformity
assessment path involving type examination of the devices and auditing of the
Company's quality system used in production. There are also specific
requirements related to clinical investigation and reporting of adverse
incidents.

         Once CE marked medical devices are placed on the market, they come
under regulatory surveillance of national Competent Authorities ("CAs"). CAs are
responsible for enforcement and can restrict, prohibit or recall CE marked
devices if they are unsafe. Such negative decisions must be reviewed by the
European Commission in order to remain valid.

         Although countries of the EEA may require use of national language on
labels and instructions for use, they must accept CE marked devices in their
market without imposing additional technical requirements that would be in
violation of the MDD. There can be no assurances, however, that these countries
will always respect this principle in practice.

         The regulatory system created by the MDD does allow in practice
substantial national variations in requirements relating to clinical
investigation and reporting of adverse incidents. Pricing and reimbursement
requirements are not covered by European Union legislation and therefore can be
freely regulated by the countries of the EEA.

         Devices will be subject to, in addition to future legislation of
European Union or other countries, continued national regulation on pricing and
reimbursement, which may vary from country to country. Certain other
requirements, such as clinical investigations and post marketing surveillance,
will probably be subject to significant variation among countries. The
regulation of drugs in the European Union is subject to a separate and different
regulatory framework, which requires, among other things, premarket approval by
the applicable regulatory agencies before sale of such products.

PATENTS, TRADEMARKS AND TRADE SECRETS

         Proprietary protection for the Company's product candidates, processes
and know-how is important to the Company's business. The Company's policy is to
file patent applications to protect technology, inventions and improvements that
are considered important to the development of its business. The Company also
relies upon trade


                                        9

<PAGE>   11



secrets, know-how and continuing technological innovation to develop and
maintain its competitive position. The Company plans to aggressively prosecute
and defend its patents and proprietary technology.

         The Company owns five issued U.S. patents, three pending U.S. patent
applications, and corresponding foreign patents and patent applications relating
to its ADCON products.

         Three U.S. patents, filed solely by the Company, have been issued
covering the composition of a matter for a series of synthetic H(3) receptor
antagonist compounds. Several additional U.S. patent applications and their
corresponding foreign applications for an additional series of H(3) receptor
antagonist and one series of H(3) receptor agonist compounds, their methods of
medical use and pharmaceutical compositions, are pending. No assurance can be
given that any claims relating to these products and methods will be issued.

         In addition, one U.S. patent application concerning the anti-properdin
monoclonal antibody and two U.S. patent applications concerning the glycine
transporter and corresponding foreign applications are pending.

         The Company is prosecuting its patent applications with the United
States Patent and Trademark Office ("USPTO") but the Company does not know
whether any of its applications will issue as patents or, if any patents are
issued, whether any issued patent will provide significant proprietary
protection or will be circumvented or invalidated. During the course of patent
prosecution, the USPTO may require that the claims of a patent application be
amended if it is determined that the scope of the claims includes subject matter
that is not useful, novel, nonobvious or enabled. Furthermore, in certain
instances, the practice of a patentable invention may require a license from the
holder of dominant patent rights.

         There can be no assurance that additional patents will be obtained by
the Company or that issued patents will provide substantial protection or be of
commercial benefit to the Company. The issuance of a patent is not conclusive as
to its validity or enforceability, nor does it provide the patent holder with
freedom to operate without infringing the patent rights of others. A patent
could be challenged by litigation and, if the outcome of such litigation were
adverse to the patent holder, competitors could be free to use the subject
matter covered by the patent, or the patent holder may license the technology to
others in settlement of such litigation. The invalidation of key patents owned
by or licensed to the Company or non-approval of pending patent applications
could create increased competition, with potential adverse effects on the
Company and its business prospects. In addition, there can be no assurance that
any patents on, or applications of, the Company's technology will not infringe
patents or proprietary rights of others or that licenses that might be required
as a result of such infringement for the Company's processes or products would
be available on commercially reasonable terms, if at all.

         The Company cannot predict whether its or its competitors' patent
applications will result in valid patents being issued. Litigation, which could
result in substantial cost to the Company, may also be necessary to enforce the
Company's patent and proprietary rights and/or to determine the scope and
validity of others' proprietary rights. The Company may participate in
interference proceedings that may in the future be declared by the USPTO to
determine priority of invention, which could result in substantial cost to the
Company. There can be no assurance that the outcome of any such litigation or
interference proceedings will be favorable to the Company or that the Company
will be able to obtain licenses to technology that it may require or that, if
obtainable, such technology can be licensed at a reasonable cost.

         The patent position of biotechnology and biopharmaceutical firms
generally is highly uncertain and involves complex legal and factual questions.
To date, no consistent policy has emerged regarding the breadth of claims
allowed in biotechnology and biopharmaceutical patents. Accordingly, there can
be no assurance that patent applications owned or licensed by the Company will
result in patents being issued or that the patents will afford protection
against competitors with similar technology.




                                       10

<PAGE>   12



         The Company also attempts to protect its proprietary compounds,
products and processes by relying on trade secret laws, and on non-disclosure
and confidentiality agreements. The Company requires its employees, consultants,
outside scientific collaborators and sponsored researchers and other advisors to
execute confidentiality agreements upon the commencement of employment or
consulting relationships with the Company. These agreements generally provide
that all confidential information developed or made known to the individual
during the course of the relationships is to be kept confidential and not
disclosed to third parties except in specific circumstances. In the case of
employees, the agreements provide that any inventions conceived by the
individual within the scope of his employment shall be the exclusive property of
the Company. There can be no assurance, however, that these agreements will
provide meaningful protection for any of the Company's trade secrets in the
event of unauthorized use or disclosure of such information.

         The medical device and healthcare industries have been characterized by
extensive litigation regarding patents and other intellectual property rights,
and companies in the medical device industry have employed intellectual property
litigation to gain a competitive advantage. There can be no assurance that the
Company will not become subject to patent infringement claims or litigation or
interference proceedings declared by the USPTO to determine the priority of
invention. The defense and prosecution of intellectual property suits, USPTO
interference proceedings and related legal and administrative proceedings are
both costly and time-consuming. Litigation may be necessary to enforce patents
issued to the Company, to protect trade secrets or know-how owned by the Company
or to determine the enforceability, scope and validity of the proprietary rights
of others. Any litigation or interference proceedings will result in substantial
expense to the Company and significant diversion of effort by the Company's
technical and management personnel. An adverse determination in litigation or
interference proceedings to which the Company may become a party, including any
litigation that may arise against the Company as described in "Item 3: Legal
Proceedings" below, could subject the Company to significant liabilities to
third parties or require the Company to seek licenses from third parties or
prevent the Company from marketing its products in certain areas, or at all.
Although patent and intellectual property disputes regarding medical devices
have often been settled through licensing or similar arrangements, such
settlements may be substantial and could include ongoing royalties. Furthermore,
there can be no assurance that the necessary licenses would be available to the
Company on satisfactory terms, if at all. Adverse determinations in a judicial
or administrative proceeding or failure to obtain necessary licenses could
prevent the Company from marketing its products, which would have a material
adverse effect on the Company's business, prospects, financial condition and
results of operation.

RESEARCH AND DEVELOPMENT EXPENSES

         As a result of the Company's ongoing research and development efforts
with respect to its biosurgical products and neurological disorders programs,
the Company's research and development expenses have increased since 1997.
Research and development expenses for fiscal years ended December 31, 1999, 1998
and 1997 were approximately $12.8 million, $10.1 million and $7.1 million,
respectively. The Company employs approximately 47 individuals who are engaged
in or directly support its research and development efforts.

DOMESTIC AND FOREIGN PRODUCT SALES

         Sales of the Company's ADCON products, particularly ADCON-L, comprised
approximately 95%, 80% and 31% of the Company's revenues for years ending
December 31, 1999, 1998 and 1997, respectively. For a description of domestic
and foreign product sales and certain related information, see Note I of Notes
to Consolidated Financial Statements included herein.

EMPLOYEES

         As of December 31, 1999, the Company had 89 full-time employees, 20 of
whom held a Ph.D. or M.D. Of the Company's 89 employees, 47 were engaged in, or
directly supported, research and development, 16 were engaged in the sales and
marketing of the ADCON family of products and the remaining 26 performed
manufacturing, executive or administrative functions.

ITEM 2.           PROPERTIES.

         The Company's operations are conducted at a 50,925 square foot, leased
facility in Beachwood, Ohio, a suburb of Cleveland. The lease expires on
December 31, 2001. In addition, the Company leases a 12,400 square foot facility
in Solon, Ohio, which will be used as a manufacturing facility for its sales of
ADCON-L in the United States. This lease expires on April 30, 2009.


                                       11

<PAGE>   13



         The Company anticipates that it will relocate its headquarters and
research facility to an approximately 84,000 square-foot facility in the Village
of Highland Hills, Ohio, a suburb of Cleveland. The Company anticipates that it
will lease this facility for a 20-year term with two (2) five (5)-year
extensions. This project will be funded, in part, through state financing.

ITEM 3.           LEGAL PROCEEDINGS.

         On March 17, 2000, Derrick McKinley, M.D. filed a lawsuit against the
Company and certain of its officers in the Court of Common Pleas in Cuyahoga
County, Ohio alleging wrongful and tortious discharge and tortious interference
with employment. Such claims arose from the termination of his employment with
the Company. The complaint seeks unspecific monetary damages in an amount in
excess of $25,000 in the form of compensatory, consequential and punitive
damages. The Company believes this suit is without merit and intends to
vigorously defend this suit.

         On August 18, 1999, Vance Carter filed a lawsuit against the Company in
the Fourth Judicial District Court of Louisana alleging certain product
liability claims as a result of the use of ADCON-L during surgery. The petition
for damages alleges that as a result of being administered ADCON-L during lumbar
disc surgery, Mr. Carter has been experiencing pain and discomfort and has been
unable to return to work. The petition for damages seeks unspecific monetary
damages. The Company believes this suit is without merit and intends to
vigorously defend this suit.

         In addition, from time to time, the Company is involved in various
disputes arising in the ordinary course of business. In management's opinion,
the outcome of these matters will not have a material adverse effect on the
Company's financial position, results of operations or cash flows.

ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITYHOLDERS.

         No matter was submitted to a vote of security holders during the fourth
quarter of fiscal 1999.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

OVERVIEW

         The Company is engaged in the discovery and development of biosurgical
and therapeutic products to improve surgical outcomes and to treat neurological
disorders. The biosurgical products include the ADCON family of products,
which are proprietary, resorbable, carbohydrate polymer medical devices
designed to inhibit surgical scarring and adhesions. Based on European pivotal
clinical studies and other compliance efforts and submission of data, the
Company obtained regulatory clearance to affix CE Marking on ADCON-L and
ADCON-T/N in August 1995 and January 1996, respectively, thereby allowing
ADCON-L and ADCON-T/N to be marketed in the 19 European countries which
recognize CE Marking for lumbar disc surgery and tendon and peripheral nerve
surgeries, respectively. The Company is currently marketing ADCON-L and
ADCON-T/N through independent medical device distributors in approximately 30
countries outside the United States, including the major countries in the
European Union pursuant to its CE Marking. The Company also commenced sales of
ADCON-L in the United States in June 1998. In September 1999, the FDA issued a
warning letter to EMCM, which led to an import ban on all ADCON-L shipments to
the United States. After a successful re-inspection of EMCM's facilities, the
import ban was lifted in December 1999 and the Company resumed shipments of
ADCON-L to the United States in January 2000. In addition, the Company signed a
development and exclusive license agreement in December 1996 with Chugai for
the sale of ADCON-L and ADCON-T/N in Japan.

         The Company anticipates that a significant portion of revenue from
product sales will be derived from its ADCON family of products, primarily
ADCON-L. Further, the Company is also pursuing the development of other
biosurgical products and small molecule drug candidates for the treatment of
several neurological disorders, including ADHD, sleep disorders, anxiety,
schizophrenia and AD. In October 1994, the Company entered into a strategic
alliance with Janssen to collaborate on the discovery and development of
therapeutic models to treat AD. In May 1999, Janssen ceased funding this
endeavor. The Company believes that Janssen does not intend to select a lead
compound from the identified compounds or pursue clinical trials relating to any
such compound. The Company is in discussion with Janssen to transfer development
rights of these compounds to the Company. There can be no assurance that the
Company will be successful in obtaining such development rights from Janssen or,
if the Company is successful, that such rights will be obtained on favorable
terms. In addition, the Company receives revenues from various government grants
awarded to the Company. In June 1998, the Company received proceeds of
approximately $18.9 million in connection with the completion of a public
offering of 1,725,000 shares of Common Stock.

RESULTS OF OPERATIONS

         Years ended December 31, 1999 and 1998.

         Revenues. Total revenues for fiscal 1999 increased by approximately
$10.6 million or 61.3% to approximately $28.0 million from approximately $17.3
million in fiscal 1998. The increase in total revenues is primarily the result
of an increase in product sales, which increased to approximately $26.5 million
in 1999 from approximately $13.9 million in 1998. This increase in product sales
resulted primarily from the commercialization in the United States of the
Company's first product, ADCON-L. ADCON-L was approved for marketing in the
United States by the FDA in May 1998. The Company commenced sales of ADCON-L in
the United States in June 1998.

         The increase in total revenues for fiscal 1999 is slightly offset by a
decrease in research contracts revenues. This decrease in the Company's research
contracts revenues was due to Janssen no longer funding the collaboration
efforts with the Company. The Company's government-funded grant revenues
increased slightly in 1999 compared to 1998. This increase was a result of the
award of two Small Business Innovation Research ("SBIR") Phase II grants, one
awarded in the third quarter of 1998 and one awarded in the second quarter of
1999.

         Operating Costs and Expenses. Total operating expenses increased by
approximately $7.8 million or 35.5% to approximately $29.8 million in 1999,
compared to approximately $22.0 million in 1998. Cost of products sold increased
to $5.0 million in 1999 compared to approximately $2.5 million in 1998, and
increased, as a percentage of product sales, in 1999 to 18.8% from 17.7% 1998.
The percentage increase in 1999 was primarily due to: (1) fixed costs continuing
at anticipated levels during the last two months of 1999 when ADCON-L was unable
to be sold in the United States as a result of the import ban and (2) startup
costs associated with the new U.S. manufacturing plant.

         Research and development expenses increased by $2.7 million or 26.8 %
to approximately $12.8 million in 1999 from approximately $10.0 million in 1998.
This increase was primarily due to four factors:


                                       15

<PAGE>   17



         (1)      An increase in development expenses for Perceptin , which
                  received approval from the FDA in the fourth quarter of 1999
                  to begin Phase II clinical trials;
         (2)      The increased clinical research costs associated with the
                  initiation of the pilot clinical trials of ADCON-A;
         (3)      The increased clinical research cost associated with the pilot
                  clinical trials for the use of ADCON-L in breast augmentation
                  surgeries; and
         (4)      The start of a product development program for schizophrenia
                  and dementia involving the regulation of human glycine
                  transporters.

         Selling, general and administrative expenses increased by approximately
$2.6 million or 27.4% to approximately $12.1 million in 1999 compared to
approximately $9.5 million in 1998. This increase was primarily due to an
increase in the sales and marketing expenses and sales commissions resulting
from the sales and marketing of ADCON-L in the United States and a non-recurring
expense of $780,000 for severance obligations for former employees. These
increases were somewhat offset by a reduction to the bad debt allowance
resulting from a more favorable collection history than originally anticipated.
The 1998 expense included $647,000 of costs associated with the Company's effort
to select and finance a new building for its future research and development and
corporate headquarters facility. This project was terminated as of December 31,
1998. Since then, the Company has pursued an alternate site.

         Interest Income. Interest income increased to approximately $1.5
million in 1999 from approximately $916,000 in 1998. This increase in 1999 is
due to carrying higher short-term investments for a full year due to the
proceeds from the public offering in June 1998 and the revenue generated from
the sale of ADCON-L in the United States.

         Net Loss. Gliatech's net loss decreased to approximately $395,000 in
1999, compared to approximately $3.8 million in 1998. The decrease in net loss
is a result of ADCON-L product sales in the United States, offset somewhat by an
increase in total expenses. The net loss per common share was $0.04 in 1999,
compared to $0.44 in 1998.

         Years ended December 31, 1998 and 1997.

         Revenues. Total revenues more than tripled to approximately $17.3
million in 1998 from approximately $4.9 million in fiscal 1997. The increase in
total revenues is primarily the result of an increase in product sales, which
increased to approximately $13.9 million in 1998 from approximately $1.5 million
in 1997. This increase in product sales resulted primarily from the
commercialization in the United States of the Company's first product, ADCON-L,
which was approved for marketing by the FDA in May 1998. The Company commenced
sales of ADCON-L in the United States in June 1998.

         The Company's research contract revenues decreased by 15.4% to
approximately $2.6 million in 1998 from approximately $3.0 million in 1997.
These research contract revenues were from the Company's research contract with
Janssen, which was restructured in October 1998 to provide for further research
by the Company and revenues from Janssen until May 1999.

         The Company's government-funded grant revenues more than doubled to
approximately $846,000 in 1998 from approximately $410,000 in 1997. This
increase was a result of an increase in the number of government- funded grants
to the Company. The Company received a second Phase II SBIR award from the
National Institute of Neurological Disorders and Stroke ("NINDS") in September
1998, for the research to evaluate the histamine H(3) antagonists. The Company's
first Phase II SBIR Program grant from the NINDS was awarded in February 1997
for the research to evaluate the histamine H(3) receptor antagonists. Both Phase
II grants have a two-year term and each may provide as much as $750,000 in
funding. In addition, in 1998 the Company received three additional Phase I
grants. Two were in the second quarter, each in the amount of approximately
$98,000 from the National Institutes of Health ("NIH"). One was for the research
development of drugs for schizophrenia and dementia and the other was to
evaluate anti-properdin agents as novel anti-inflammatories. The Company
received a third Phase I grant in the third quarter from NIH for approximately
$100,000 to research combinatorial construction of novel imidazole libraries. In
1997 the Company received two Phase I grants in the third quarter. One was from
NINDS in the amount of approximately $100,000, and the other from the National
Institute of Nursing Research ("NINR") in the amount of approximately $99,000.

         Operating Costs and Expenses. Total operating costs and expenses
increased by 78.9% to approximately $22.0 million in 1998, compared to
approximately $12.3 million in 1997. Cost of products sold increased to
approximately $2.5 million in 1998 compared to approximately $614,000 in 1997,
but decreased, as a percentage of


                                       16

<PAGE>   18



products sales in 1998 to 17.7% from 40.0% in 1997. The percentage decrease in
1998 was primarily due to: (1) the favorable impact of the unit sales prices of
ADCON-L in the United States and (2) increased production volumes.

         Research and development expenses increased by 41.0% to approximately
$10.1 million in 1998 from approximately $7.1 million in 1997. This increase was
primarily due to: (1) an increase in development expenses for the Company's lead
compound for its Cognition Modulation program, which commenced a Phase I human
clinical trial in the fourth quarter of 1998 and (2) increased clinical research
costs associated with the pilot clinical trial of ADCON-P, which was completed
in the third quarter of 1998.

         Selling, general and administrative expenses increased 110.2% to
approximately $9.5 million in 1998 compared to approximately $4.5 million in
1997. This increase was primarily due to an increase in the sales and marketing
expenses and sales commissions resulting from the sales and marketing of ADCON-L
in the U.S. The increase was also due to $647,000 of costs associated with the
Company's efforts to select and finance a new building for its future research
and development and corporate headquarters facilities. This project was
terminated as of December 31, 1998 when project costs were estimated to be
substantially in excess of available funding.

         Interest Income. Interest income increased to approximately $916,000 in
1998 from approximately $824,000 in 1997. This increase in 1998 was primarily
due to higher cash, cash equivalents and short-term investment balances due to
the proceeds from the public offering in June 1998.

         Net Loss. Gliatech's net loss decreased to approximately $3.8 million
in 1998, compared to approximately $8.6 million in 1997. The decrease in net
loss is a result of ADCON-L product sales in the U.S., offset somewhat by an
increase in total expenses. The diluted net loss per common share was $0.44 in
1998, compared to approximately $1.16 in 1997.

LIQUIDITY AND CAPITAL RESOURCES

         In order to preserve principal and maintain liquidity, the Company's
funds are invested primarily in commercial paper and other short-term
investments. As of December 31, 1999 and December 31, 1998, the Company's cash
and cash equivalents, short-term and long term investments totaled approximately
$20.8 million and approximately $26.4 million, respectively. The Company expects
that its existing capital resources, interest earned thereon, and product sales
will enable the Company to maintain its current and planned operations for the
foreseeable future.

         Prior to the commercialization of ADCON-L in the United States, the
Company historically financed its operations primarily through the private
placement and public offering of its equity securities, research contract
licensing fees, and, to a lesser extent, through federally sponsored research
grants. In June 1998, the Company raised additional funds through a public
offering of 1,725,000 shares of its Common Stock at a price of $12.00 per share,
including the exercise of the over-allotment option of 225,000 shares. The net
proceeds to the Company from this offering were approximately $18.9 million. The
Company also has established a $1.5 million line of credit with a bank. As of
December 31, 1999, the Company had no borrowings against the line of credit.

         In the second quarter of 1999 the Company was awarded a third Phase II
SBIR Program grant from the National Cancer Institute ("NCI"), a division of the
NIH, for the research of inhibition of postoperative gynecological adhesions. In
September 1998 the Company was awarded a Phase II SBIR Program grant from the
NINDS for research evaluating H (3) agonists. Each of these Phase II grants has
a two-year term and each may provide as much as approximately $750,000 in
funding. The Company was also awarded a Phase I SBIR grant for up to
approximately $100,000 in the third quarter of 1998 to aid in additional
research studies. In the second quarter of 1998 the Company was awarded two
Phase I grants for up to approximately $98,000 each from the National Heart,
Lung and Blood Institute and National Institute of Mental Health, both
divisions of the NIH. In February 1997 the Company was awarded a two-year Phase
II SBIR Program grant from NINDS for research evaluating histamine H (3)
receptor antagonists to treat ADHD, which may provide as much as $750,000 in
funding. In addition, in the fourth quarter of 1997 the Company was awarded two
Phase I SBIR grants for up to approximately $100,000 each from the NINDS and
the NINR division of the NIH. In 1996, the Company received revenues from a
Phase I SBIR grant for up to approximately $100,000 from the NINDS division of
the NIH relating to the development of histamine H (3) receptor agents. If the
Company is successful in other Phase I research, additional Phase II awards may
be sought for funding to aid in further development of pharmaceutical
compounds,


                                       17

<PAGE>   19



however, there is no assurance that such Phase I research will be successful or
that additional funding will be obtained.

         The Company does not expect to generate a positive cash flow from
operations until the fourth quarter of 2000 due to the substantial costs for
commercialization of ADCON-L, additional research and development costs for its
other biosurgical products and costs related to its neurosurgical disorders
programs, preclinical testing, clinical trials and operating expenses associated
with supporting such activities. The Company's ability to generate a positive
cash flow from operations is dependent upon several factors, including the
timing and content of decisions by the FDA. There is no assurance when the
Company will generate a positive cash flow, if at all.

         The Company may need to raise substantial additional capital to fund
its operations prior to such time. The Company's future capital requirements
will depend on, and could increase as a result of many factors, including, but
not limited to, the cost for commercialization of ADCON-L, the commercialization
success of its ADCON family of products, the progress of the Company's research
and development, including the costs related to its Cognition
Modulation Perceptin, AD, schizophrenia and other neurological disorders
programs, the scope, timing and results of preclinical studies and clinical
trials, the cost and timing of obtaining regulatory approvals, the Company's
success in obtaining the strategic alliances required to fund certain of its
programs, the rate of technological advances, determinations as to the
commercial potential of certain of the Company's product candidates, the status
of competitive products and the establishment of additional manufacturing
capacity.

         The Company from time to time is involved in various stages of
discussion or negotiation regarding acquisitions or mergers and from time to
time other strategic alternatives. As of the date hereof, no definitive
agreement with respect to any such transaction or other strategic alternative
has been entered into.

         Net Operating Loss Carryforwards. As of December 31, 1999, the Company
has available net operating loss carryforwards of approximately $29.6 million,
and research and development credit carryforwards of approximately $3.6 million.
These carryforwards expire at various dates between 2003 and 2013. The Company
has offset the tax benefit of the net operating loss and tax credit
carryforwards with a valuation allowance, as realization of the benefit is not
assured. Pursuant to the Tax Reform Act of 1986, the utilization of net
operating loss and research and development tax credit carryforwards for tax
purposes may be subject to an annual limitation if a cumulative change in
ownership of more than 50% occurs over a three-year period. The future issuance
of securities by the Company and/or sales of securities by the Company's
principal stockholders could result in such a change in ownership. See Note F of
Notes to Consolidated Financial Statements included herein.

YEAR 2000.

         The Company did not experience any significant malfunctions or errors
in its operating or business systems when the date changed from 1999 to 2000.
Based on operations since January 1, 2000, the Company does not expect any
significant impact to its on-going business as a result of the "Year 2000
issue." However it is possible that the full impact of the date change, which
was of concern due to computer programs that use two digits instead of four
digits to define years, has not been fully recognized. For example, it is
possible that Year 2000 or similar issues such as leap year-related problems may
occur with billing, payroll, or financial closing at month, quarterly or
year-end. The Company believes that any such problems are likely to be minor and
correctable. In addition, the Company could still be negatively impacted if the
Year 2000 or similar issues adversely affect its customers or suppliers. The
Company currently is not aware of any significant Year 2000 or similar problems
that have arisen for its customers and suppliers.

         The Company expended approximately $20,000 on Year 2000 readiness
efforts from 1998 to 1999. These efforts included replacing some outdated,
noncompliant hardware and noncompliant software as well as identifying and
remediating Year 2000 problems. The funds for Year 2000 readiness were from
normal operating cash flow.

EURO CONVERSION.

         On January 1, 1999, eleven of the fifteen countries (the "Participating
Countries") that are members of the European Union established a new uniform
currency known as the "Euro." The currencies existing prior to such date in the
Participating Countries will be phased out during the transition period
commencing January 1, 1999 and ending January 1, 2002. During such transition
period both the Euro and the existing currencies will be available in the
Participating Countries. Although certain of the Company's products are being
sold in the Participating Countries through independent distributors, the
Company receives revenues from such sales in U.S. dollars. As a


                                       18

result, the Company does not anticipate that the introduction and use of the
Euro will materially affect the Company's business, prospects, results of
operations or financial condition.

FORWARD-LOOKING STATEMENTS.

         Certain statements in this Annual Report on Form 10-K constitute
"forward-looking statements." When used in this Report, the words "believes,"
"anticipates," "expects," "intends" and other predictive, interpretive and
similar expressions are intended to identify such forward-looking statements.
Such forward-looking statements involve known and unknown risks, uncertainties
and other factors that may cause the actual results of the Company to be
different from expectations expressed or implied by such forward-looking
statements. Such factors include, but are not limited to, commercial uncertainty
of regulatory approvals of the Company's ADCON products, including the timing
and content of decisions made by the FDA, commercial uncertainty of market
acceptance of the Company's ADCON family of products, delays in product
development of additional ADCON products, uncertainty of outcomes of future FDA
audits and inspections, uncertainty due to the early stage of development for
the neurological disorders programs, the possible need for additional funding,
the ability of the Company to establish and maintain collaborative arrangements
with others, the potential market size for ADCON products, the ability to
extend research collaborations, the productivity of distributors of ADCON
products, shortages of supply of ADCON products from the Company's sole
manufacturer, the ability of the Company to commence manufacturing of its ADCON
products at its manufacturing facility located in the United States, the lack
of supply of raw materials for the Company's products, uncertainty of future
profitability, uncertainties related to the Company's proprietary rights in its
products, the loss of key management, and personnel and technological change.
These statements are based on certain assumptions and analysis made by the
Company in light of its experience and its perception of historical trends,
current conditions, expected future developments and other factors it believes
are appropriate in the circumstances. Such statements are subject to a number
of other assumptions, risks, uncertainties, general economic and business
conditions, and the business opportunities (or lack thereof) that may be
presented to and pursued by the Company. Prospective investors are cautioned
that any such statements are not guarantees of future performance and that
actual results or developments may differ materially from those projected in
the forward-looking statements. The accompanying information contained in this
Annual Report on Form 10-K, including, without limitation, the information set
forth in this section and under "Item 1: Business," identifies important
factors that could cause such differences.

ITEM 7A.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

         The Company does not enter into derivative financial instruments. The
Company primarily invests in commercial paper and corporate bonds that have
short-term maturities. The Company has no outstanding debt. Exposure to foreign
currency has been minimal because the Company's foreign product sales are in
U.S. currency. As a result, the Company believes that its market risk exposure
is not material to the Company's financial position, liquidity or results of
operations.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

Board of Directors and Stockholders
Gliatech Inc.

We have audited the accompanying consolidated balance sheets of Gliatech Inc.
and Subsidiaries as of December 31, 1999 and 1998, and the related consolidated
statements of operations, changes in stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1999. Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Gliatech Inc. and
Subsidiaries at December 31, 1999 and 1998, and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally
accepted in the United States. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

A. BACKGROUND AND ACCOUNTING POLICIES

Background

Gliatech Inc. is engaged in the discovery and development of biosurgical and
therapeutic products to improve surgical outcomes of patients and to treat
neurological disorders. The biosurgical products include the ADCON family of
products and a proprietary monoclonal antibody to block the inappropriate
activation of the complement pathway. The ADCON family of products consist of
proprietary, resorbable, carbohydrate polymer medical devices designed to
inhibit surgical scarring and adhesions. The Company is also pursuing the
development of small molecule drug candidates for the treatment of several
neurological disorders, including Attention Deficit Hyperactive Disorder
("ADHD"), sleep disorders, anxiety, schizophrenia and Alzheimer's disease
("AD").

Historically, since commencing operations in 1988, the Company had been a
development stage company. However, the Company introduced its first product,
ADCON-L, in the United States during 1998, resulting in significant product
sales. As a result, the Company no longer considers itself a development stage
company. The Company recognizes revenue from product sales upon shipment.

The consolidated financial statements reflect the financial position and results
of operations of Gliatech Inc. and its wholly-owned subsidiaries (the
"Company"). Intercompany balances and transactions have been eliminated.

Cash and cash equivalents

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. The carrying amount of the
Company's cash equivalents approximates fair value due to the short maturity of
those investments. Cash equivalents are primarily commercial paper.

Short and long term investments

The Company's short-term and long-term investments, all of which are classified
as available-for-sale, consist primarily of corporate bonds and commercial
paper. Such investments are stated at fair market value with unrealized gains
and losses charged or credited to shareholders' equity. Investments with
maturity dates of less than one year are classified as short-term; investments
with maturity dates of more than one year are classified as long-term.

Inventories

Inventories are stated at the lower of cost or market and are valued using the
first-in, first-out method.

Property and equipment

Property and equipment are stated at cost. Laboratory, manufacturing and office
equipment and leasehold improvements are depreciated on the straight-line basis
over the shorter of the estimated useful lives or the lease period (3 to 10
years).

Patent rights and trademarks

Patent rights are amortized on the straight-line basis over the shorter of the
estimated useful life of the patented technology or the useful life of the
patent, beginning at the time the patent is granted. Costs associated with
patents that are abandoned are expensed at the date of abandonment. Trademark
costs are amortized on the straight-line basis over the estimated useful life of
the trademark, beginning at the time the trademark is granted.

                                       25

<PAGE>   27


Government grants

Revenues from government grants are recognized ratably over the period of the
grant.

Research contracts and licensing fee revenue

Revenue from the research collaboration agreements are recorded when earned as
defined under the terms of the agreements. Periodic research funding payments
received which are related to future performance are deferred and recognized as
income when earned. Licensing fees and other milestone payments are recognized
as income when earned.

Research and development

Research and development expenditures are expensed when incurred.

Income taxes

The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for
Income Taxes."

Stock-based compensation

The Company accounts for stock-based compensation in accordance with APBO No.
25, "Accounting for Stock Issued to Employees."

Use of estimates

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

Reclassifications

Certain prior year amounts have been reclassified to conform with current year
financial statement presentation.

F. INCOME TAXES

At December 31, 1999, the Company has available net operating loss carryforwards
of approximately $29.6 million. In addition, the Company has approximately $3.6
million in research and development tax credit carryforwards. Such losses and
carryforwards may be used to reduce future tax liabilities and expire at various
dates between 2003 and 2014. The Company has offset the tax benefit of the net
operating loss and tax credit carryforwards and other deferred tax assets with a
valuation allowance as realization of the benefits is not assured.

Pursuant to the Tax Reform Act of 1986, the utilization of net operating loss
and research and development tax credit carryforwards for tax purposes may be
subject to an annual limitation if a cumulative change in ownership of more than
50% occurs over a three-year period.


G. RIGHTS PLAN

On July 1, 1997, the Company declared a dividend distribution of one right (a
"Right") for each outstanding share of Common Stock. The terms of the Rights are
set forth in the Rights Agreement, dated July 1, 1997, between the Company and a
rights agent. The Rights generally will become exercisable and allow a holder to
acquire Common Stock at a discounted price if a person or group acquires 15% or
more of the outstanding shares of Common Stock of the Company. The Rights
Agreement was amended in November 1999 to allow a certain holder to acquire up
to 20% of the outstanding shares of Common Stock without Rights becoming
exercisable. The Company is also subject to provisions of state law which will
prohibit the Company from engaging in any "business combination" with a person
who, together with affiliates and associates, owns 15% or more of the Company's
Common Stock (an "Interested Stockholder") for a period of three years following
the date that such person became an Interested Stockholder, unless the business
combination is approved in a prescribed manner or certain other requirements are
satisfied.

H. STOCK OPTION PLANS

The Company has a 1989 Stock Option Plan for employees and 1992 and 1995 Stock
Options Plans for members of the Company's Board of Directors. These plans
provide for the granting of 2,120,000 options to employees and 340,000 options
to Directors. These options generally vest over a three or four year period and
become exercisable in part one year after date of grant and expire at the end of
ten years. At December 31, 1999, there were 494,217 options available for future
grants.

A summary of the status of the Company's three stock option plans as of December
31, 1999, 1998 and 1997 and changes during the years then ended is presented
below:

At December 31, 1999 2,132,258 shares of common stock are reserved for issuance
under the stock options plans.

The Company applies APBO No. 25, "Accounting for Stock Issued to Employees" and
related interpretations in accounting for its plans. Accordingly, no
compensation cost has been recognized for the fixed stock option plans to
employees except for modifications made in 1999 to certain stock options
previously granted to terminated employees, which resulted in expense of
$372,000. Had compensation cost for the Company's three stock-based compensation
plans been determined based on the fair value at the grant dates for awards
under those plans consistent with the method of SFAS No. 123, "Accounting for
Stock-Based Compensation," the Company's net loss and net loss per share would
have increased to the pro forma amounts indicated below:

J. RESEARCH COLLABORATION AGREEMENTS

In October 1994, the Company established a research and development
collaboration with Janssen Pharmaceutica, N.V. ("Janssen"), a wholly owned
subsidiary of Johnson & Johnson, for the discovery and development of compounds
suitable for the treatment of Alzheimer's disease. In October 1998, this
collaboration was restructured to provide for further research by the Company
until May 1999. In May 1999, Janssen ceased funding these research efforts and
elected not to renew the research collaboration.

K. RESEARCH, CLINICAL TRIAL, CONSULTING AND LICENSE AGREEMENTS

Since beginning operations, the Company has entered into research agreements and
clinical trial agreements with universities and third parties and consulting
agreements with scientific advisors. The research agreements require the Company
to fund certain research activities, and are generally renewable on an annual
basis. In return, the Company has rights to obtain and use exclusive licenses
for the results of the research. Under license agreements with various
universities, ownership of all patents resulting from research agreements will
remain with the universities or researchers. The Company is required to incur
all cost associated with applying for and maintaining the patents. The Company
generally will obtain exclusive worldwide licensing rights and is required to
remit fixed percentages, as defined, of the net selling price of licensed
products and royalties received from sublicensees to the universities and
researchers. The clinical trial agreements require the Company to fund the
performance of specific clinical procedures and the cost of administering the
clinical trials.

As of December 31, 1999, minimum commitments under research, clinical trial and
consulting agreements are $1,783,850 for 2000.


L. SETTLEMENT OF CLAIM AND CONTINGENCIES

In 1995, a dispute regarding inventorship of the ADCON products and the rights
of Case Western Reserve University ("CWRU") to receive royalties from sales of
ADCON products arose between the Company and CWRU. After extensive discussions
between the Company and CWRU, a complaint was filed by the Company on September
8, 1997 in the United States District Court Northern District of Ohio, Eastern
Division ("Court") against CWRU and one of its employees, requesting the Court
to confirm that there was no error in the omission of the employee as a named
inventor of the Company's patents. The complaint was filed in response to
repeated statements to the Company and the general public made by the employee
and CWRU alleging that the inventorship of the patent was in error because the
employee was not named. The complaint did not seek monetary damages. An
agreement in principle was reached between the Company and CWRU in 1997 and the
Company recorded a charge of $2,025,000 based on the fair value of the Company's
common stock at that time. The Company recorded the offset to the charge as a
component of stockholders' equity in 1997 since the settlement was to be made in
shares of common stock. In March 1998 the suit was dismissed pursuant to the
terms and conditions of a Settlement Agreement among

                                      30
<PAGE>   32
the Company, CWRU and the employee, and the Company issued 200,000 shares of
common stock to CWRU and the employee.

In addition, from time to time, the Company is involved in various disputes
arising in the ordinary course of business. In management's opinion, the outcome
of these matters will not have a material adverse effect on the Company's
financial position, results of operations or cash flows.


M. YEAR END ADJUSTMENTS (UNAUDITED)

In the fourth quarter of 1999 the Company recorded certain non-recurring and
year-end adjustments that reduced selling, general and administrative expenses.
In the fourth quarter, the Company settled a claim with a former distributor of
ADCON-L for approximately $184,000. The Company had previously recorded an
accrual for this loss contingency of $400,000. The Company reduced its bad debt
allowance by $347,000 due to a more favorable collection history than originally
anticipated. The Company also reduced its year end bonus accrual by $471,000 due
to fourth quarter losses caused by the Company being unable to ship ADCON-L to
its U.S. customers for the last two months of the year. These changes in
estimates were offset by a non-recurring expense of $780,000 related to
severance arrangements with former employees.

                  Due to the lack of significant sales, the trade receivable

         Product, but prior to submission of the first BLA for such Product,
         Gliatech shall pay to ABX [***] of Sublicensing Revenues for such
         Product.

         If such Sublicense for such Product is granted following submission of
         the first BLA for such Product, Gliatech shall pay to ABX [***] of
         Sublicensing Revenues for such Product.

                   b. Gliatech shall have the right to offset any milestone
payment paid under Section 5.2.1 above with respect to a Product against the
Sublicensing Revenues fee payments thereafter owing under Section 5.3.2(a) above
with respect to such Product.

             5.3.3 NET SALES ROYALTY. Gliatech shall pay to ABX a royalty with
respect to each Product equal to (a) [***] of the aggregate Net Sales of such
Product by Gliatech and its Affiliates, and (b) the greater of (i) the
applicable percentage set forth in Section 5.3.2(a) of the cash royalty payments
(that are calculated as a percentage of sales of such Product) received by
Gliatech or its Affiliates from each Sublicensee in consideration for or
otherwise in connection with the grant of a Sublicense with respect to such
Product to such Sublicensee, or (ii) [***] of the aggregate Net Sales of such

each Product under Sections 5.3.2 and 5.3.3 shall continue for such Product in
each country until (a) if, as of the First Commercial Sale of such Product in
such country, there exists a Patent Claim in the country where such Product is
made, used or sold that covers (i) Gliatech's or its Affiliate's or
Sublicensee's manufacture, use or sale of such Product, or (ii) XenoMouse
Animals or their use, such date as no such Patent Claim exists in the country

      6. ACCOUNTING AND RECORDS

         6.1 FEE AND ROYALTY REPORTS AND PAYMENTS. Commencing with the first
calendar quarter in which the first Fee and Royalty Commencement Date occurs,
Gliatech shall

<PAGE>   15



make written reports to ABX within thirty (30) days after the end of each
calendar quarter, stating in each such report the number, description, and
aggregate Net Sales of Product sold during the calendar quarter, the
Sublicensing Revenues for such calendar quarter, and the calculation of the
royalties payable under Article 5 above. Concurrently with the making of such
reports, Gliatech shall pay to ABX all amounts payable pursuant to Article 5
above.

         6.2 RECORDS; INSPECTION. Gliatech shall keep (and cause its
Affiliates and Sublicensees to keep) complete, true and accurate books of
account and records for the purpose of determining the fee and royalty amounts
payable to ABX under this Agreement. Such books and records shall be kept at the
principal place of business of Gliatech or its Affiliates or Sublicensees, as
the case may be, for at least three years following the end of the calendar
quarter to which they pertain. Such records of Gliatech or its Affiliates will
be open for inspection during such three-year period by representatives of ABX
(which representatives may also represent XT) for the purpose of verifying the
fee and royalty statements. Gliatech shall require each of its Sublicensees to
maintain similar books and records and to open such records for inspection
during normal business hours upon reasonable prior written notice during the
same three-year period by a representative of Gliatech reasonably satisfactory
to ABX on behalf of, and as required by, ABX for the purpose of verifying the
fee and royalty statements. All such inspections may be made no more than once
each calendar year at reasonable times mutually agreed by Gliatech and ABX. The
representative of ABX will be obliged to execute a reasonable confidentiality
agreement prior to commencing any such inspection. Inspections conducted under
this Section 6.2 shall be at the expense of ABX, unless a variation or error
producing an increase exceeding ten percent (10%) of the amount stated for any
period is established in the course of any such inspection, whereupon all costs
relating to the audit of such period will be paid by Gliatech.

         6.3 PAYMENT METHOD. All payments by Gliatech to ABX hereunder shall
be in United States Dollars in immediately available funds and shall be made by
wire transfer from a United States bank located in the United States to such
bank account as designated by ABX to Gliatech.

         6.4 CURRENCY CONVERSION. If any currency conversion shall be
required in connection with the calculation of royalties hereunder, such
conversion shall be made using the selling exchange rate for conversion of the
foreign currency into United States Dollars, quoted for current transactions
reported in THE WALL STREET JOURNAL for the last business day of the calendar
quarter to which such payment pertains.

         6.5 LATE PAYMENTS. Any payments due from Gliatech that are not paid
on the date such payments are due under this Agreement shall bear interest at a
rate per annum equal to the lesser of (i) the prime rate as reported by the Bank
of America in San Francisco, California on the date such payment is due, plus an
additional one percent (1%), or (ii) the maximum rate permitted by applicable
law, in each case calculated on the number of days such payment is delinquent.
This Section 6.5 shall in no way limit any other remedies available to any
party.

         6.6 WITHHOLDING TAXES. All payments required to be made pursuant to
Article 5 above shall be without deduction or withholding for or on account of
any taxes or

and [***] to the other party.

         9.4 INFRINGEMENT CLAIMS. Subject to Section 9.6 below, if the

<PAGE>   21


      10. INDEMNIFICATION

          10.1 ABX. ABX shall indemnify and hold harmless Gliatech, and its
directors, officers, employees and agents, from and against all losses,
liabilities, damages and expenses, including reasonable attorneys' fees and
costs (collectively, "Liabilities"), resulting from any claims, demands, actions
or other proceedings by any Third Party arising from (a) the material breach of
any representation, warranty or covenant by ABX under this Agreement, (b) any
use, handling or storage by ABX of the Gliatech Materials and Information or the
Research Program Materials and Information, (c) the use, sale, handling or
storage by ABX of the Antibody or the Products, or (d) any use by ABX of the
Confidential Information of Gliatech; PROVIDED, HOWEVER, that ABX shall not be
obligated to indemnify or hold harmless Gliatech for such Liabilities to the
extent that such Liabilities arise from the gross negligence or willful
misconduct of Gliatech.

          10.2 GLIATECH. Gliatech shall indemnify and hold harmless ABX, and
its directors, officers, employees and agents, from and against all Liabilities
resulting from any claims, demands, actions or other proceedings by any Third
Party arising from (a) the material breach of any representation, warranty or
covenant by Gliatech under this Agreement, (b) any use, handling or storage by
Gliatech of the ABX Materials and Information or the Research Program Materials
and Information, (c) the manufacture, use, sale, handling or storage by
Gliatech, its Affiliates or Sublicensees of the Products (without regard to
culpable conduct), or (d) any use by Gliatech of the Confidential Information of
ABX; PROVIDED, HOWEVER, that Gliatech shall not be obligated to indemnify or
hold harmless ABX for such Liabilities to the extent that such Liabilities arise
from the gross negligence or willful misconduct of ABX.

          10.3 PROCEDURE. If a party (an "Indemnitee") intends to claim
indemnification under this Article 10, it shall promptly notify the indemnifying
party (the "Indemnitor") in writing of any claim, demand, action or other
proceeding for which the Indemnitee intends to claim such indemnification, and
the Indemnitor shall have the right to participate in, and, to the extent the
Indemnitor so desires, to assume the defense thereof with counsel mutually
satisfactory to the parties with the fees of such counsel to be paid by the
Indemnitor; PROVIDED, HOWEVER, that an Indemnitee shall have the right to retain
its own counsel, with the fees and expenses to be paid by the Indemnitor, if
representation of such Indemnitee by the counsel retained by the Indemnitor
would be inappropriate due to actual or potential differing interests between
such Indemnitee and any other party represented by such counsel in such
proceeding. The indemnity agreement in this Article 10 shall not apply to
amounts paid in settlement of any claim, demand, action or other proceeding if
such settlement is effected without the consent of the Indemnitor, which consent
shall not be withheld or delayed unreasonably. The failure to deliver written
notice to the Indemnitor within a reasonable time after the commencement of any
such action, if prejudicial to its ability to defend such action, shall relieve
such Indemnitor of any liability to the Indemnitee under this Article 10, but
the omission so to deliver written notice to the Indemnitor shall not relieve it
of any liability that it may have to any party claiming indemnification
otherwise than under this Article 10. The party claiming indemnification under
this Article 10, its employees and agents, shall reasonably cooperate with the
Indemnitor and its legal representatives in the investigation of any claim,
demand, action or other proceeding covered by this indemnification.

<PAGE>   22


          10.4 INSURANCE. Gliatech shall maintain insurance, including

development, manufacture and sale of its other products. ABX shall be named as
an additional insured on any such Gliatech policies. Gliatech shall maintain
such insurance for so long as it continues to develop, manufacture or sell any
Products, and thereafter for so long as Gliatech customarily maintains insurance
for itself covering the development, manufacture and sale of its other products.

                          Form of Severance Agreement

                           [Gliatech Inc. Letterhead]



[Name of employee]
[Address of employee]


Dear _____________:

                  Gliatech Inc. (the "Company") recognizes that, as is the case
for most publicly held companies, the possibility of a change in control exists.
The Company wishes to ensure that its senior executives and management are not
distracted from performing their duties in the event of a proposed or actual
transaction involving a change of control. Accordingly, the Company has
determined that as an additional inducement for you (the "Executive") to
continue to remain in the employ of the Company and to assure itself of both
present and future continuity of management, the Company agrees to provide the
Executive with severance benefits under the following circumstances pursuant to
the following terms and conditions (the "Agreement"):

                  1. (a) Term. This Agreement shall commence as of the date
hereof and expire as of the later of (i) the close of business on December 31,
2002, or (ii) the expiration of the Severance Period (as described below);
provided, however, that (A) commencing on January 1, 2003 and each January 1
thereafter, the term of this Agreement will automatically be extended for an
additional year unless, not later than September 30 of the immediately preceding
year, the Company or the Executive shall have given notice that it or the
Executive, as the case may be, does not wish to have the Term extended and (B)
subject to the last sentence of Section 9, if, prior to a Change in Control (as
described below), the Executive ceases for any reason to be an employee of the
Company and any entity in which the Company directly or indirectly beneficially
owns 50% or more of the outstanding Voting Stock (a "Subsidiary"), thereupon
without further action this Agreement will immediately terminate and be of no
further effect (the "Term"). For purposes of this Section 1(a), the Executive
shall not be deemed to have ceased to be an employee of the Company and any
Subsidiary by reason of the transfer of Executive's employment between the
Company and any Subsidiary, or among any Subsidiaries.

                  (b) Change in Control. For purposes of this Agreement, "Change
in Control" means the occurrence during the Term of any of the following events:

                           (i) The Company is merged, consolidated or
         reorganized into or with another corporation or other legal person, and
         as a result of such merger, consolidation or reorganization less than a
         majority of the combined voting power of the then-outstanding voting
         stock (the "Voting Stock") of such corporation or person immediately
         after such transaction is held in the aggregate by the holders of
         Voting Stock of the Company immediately prior to such transaction;

                           (ii) The Company sells or otherwise transfers all or
         substantially all of its assets to another corporation or other legal
         person, and as a result of such sale or transfer less than a majority
         of the combined voting power of the then-outstanding Voting Stock of
         such corporation or person immediately after such sale or transfer is
         held in the
<PAGE>   2
         aggregate by the holders of Voting Stock of the Company immediately
         prior to such sale or transfer;

                           (iii) There is a report filed on Schedule 13D or
         Schedule 14D-1 (or any successor schedule, form or report), each as
         promulgated pursuant to the Securities Exchange Act of 1934 ("Exchange
         Act"), disclosing that any person (as the term "person" is used in
         Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) (a "Person")
         has become the beneficial owner (as the term "beneficial owner" is
         defined under Rule 13d-3 or any successor rule or regulation
         promulgated under the Exchange Act) of securities representing 20% or
         more of the combined voting power of the then-outstanding Voting Stock
         of the Company;

                           (iv) The Company files a report or proxy statement
         with the Securities and Exchange Commission pursuant to the Exchange
         Act disclosing in response to Form 8-K or Schedule 14A (or any
         successor schedule, form or report or item therein) that a change in
         control of the Company has occurred or will occur in the future
         pursuant to any then-existing contract or transaction; or

                           (v) If, during any period of two consecutive years,
         individuals who at the beginning of any such period constitute the
         Directors of the Company cease for any reason to constitute at least a
         majority thereof; provided, however, that for purposes of this clause
         (v) each Director who is first elected, or first nominated for election
         by the Company's stockholders, by a vote of at least two-thirds of the
         Directors of the Company (or a committee thereof) then still in office
         who were Directors of the Company at the beginning of any such period
         will be deemed to have been a Director of the Company at the beginning
         of such period, but excluding, for this purpose, any such Director
         whose initial assumption of office occurs as a result of an actual or
         threatened election contest (within the meaning of Rule 14a-1 of the
         Exchange Act) with respect to the election or removal of Directors or
         other actual or threatened solicitation of proxies or consents by or on
         behalf of a Person other than the Board of Directors of the Company
         (the "Board").

Notwithstanding the foregoing provisions of Section 1(b)(iii) or 1(b)(iv),
unless otherwise determined in a specific case by majority vote of the Board, a
"Change in Control" shall not be deemed to have occurred for purposes of Section
1(b)(iii) or 1(b)(iv) solely because (A) the Company, (B) a Subsidiary, or (C)
any Company-sponsored employee stock ownership plan or any other employee
benefit plan of the Company or any Subsidiary either files or becomes obligated
to file a report or a proxy statement under or in response to Schedule 13D,
Schedule 14D-1, Form 8-K or Schedule 14A (or any successor schedule, form or
report or item therein) under the Exchange Act disclosing beneficial ownership
by it of shares of Voting Stock, whether equal to or in excess of 20% or
otherwise, or because the Company reports that a change in control of the
Company has occurred or will occur in the future by reason of such beneficial
ownership.

                  2. Operation of Agreement. This Agreement will be effective
and binding immediately upon its execution, but, notwithstanding anything in
this Agreement to the contrary, this Agreement will not be operative unless and
until a Change in Control (as defined below) occurs. Upon the occurrence of a
Change in Control at any time during the Term, without further


                                        2
<PAGE>   3
action, this Agreement shall become immediately operative, including, without
limitation, the last sentence of Section 9 notwithstanding that the Term may
have theretofore expired.

                  3. Termination Following a Change in Control. (a) In the event
of the occurrence of a Change in Control, the Executive's employment may be
terminated by the Company or any Subsidiary during the period of time commencing
on the date of the first occurrence of a Change in Control and continuing until
the earlier of (i) the first anniversary of the occurrence of the Change in
Control, or (ii) the Executive's death; provided, however, that commencing on
each anniversary of the Change in Control, this period will automatically be
extended for an additional year unless, not later than 90 calendar days prior to
such anniversary date, either the Company or the Executive shall have given
written notice to the other that this period is not to be so extended (the
"Severance Period"). In the event of such termination, the Executive shall be
entitled to the benefits provided by Section 4 unless such termination is the
result of the occurrence of one or more of the following events:

                           (i) The Executive's death;

                           (ii) If the Executive becomes permanently disabled
         within the meaning of, and begins actually to receive disability
         benefits pursuant to, the long-term disability plan in effect for, or
         applicable to, Executive immediately prior to the Change in Control; or

                           (iii) Prior to any termination pursuant to Section
         3(b) or Section 3(c), the Executive shall have:

                                    (x) been convicted of a criminal violation
                           involving fraud, embezzlement or theft in connection
                           with his duties or in the course of his employment
                           with the Company or any Subsidiary;

                                    (y) committed intentional wrongful damage to
                           property of the Company or any Subsidiary; or

                                    (z) committed intentional wrongful
                           disclosure of secret processes or confidential
                           information of the Company or any Subsidiary;

         and any such act shall have been demonstrably and materially harmful to
         the Company ("Cause"). For purposes of this Agreement, no act or
         failure to act on the part of the Executive shall be deemed
         "intentional" if it was due primarily to an error in judgment or
         negligence, but shall be deemed "intentional" only if done or omitted
         to be done by the Executive not in good faith and without reasonable
         belief that the Executive's action or omission was in the best interest
         of the Company. Notwithstanding the foregoing, the Executive shall not
         be deemed to have been terminated for "Cause" hereunder unless and
         until there shall have been delivered to the Executive a copy of a
         resolution duly adopted by the affirmative vote of not less than three
         quarters of the Board then in office at a meeting of the Board called
         and held for such purpose, after reasonable notice to the Executive and
         an opportunity for the Executive, together with the Executive's counsel
         (if the Executive chooses to have counsel present at such meeting), to
         be heard before the Board, finding that, in the good faith opinion of
         the Board, the Executive had committed


                                        3
<PAGE>   4
         an act constituting "Cause" as herein defined and specifying the
         particulars thereof in detail. Nothing herein will limit the right of
         the Executive or his beneficiaries to contest the validity or propriety
         of any such determination.

If, during the Severance Period, the Executive's employment is terminated by the
Company or any Subsidiary other than pursuant to Section 3(a), the Executive
will be entitled to the benefits provided by Section 4 hereof.

                  (b) In the event of the occurrence of a Change in Control, the
Executive may terminate employment with the Company and any Subsidiary during
the Severance Period with the right to severance compensation as provided in
Section 4 upon the occurrence of one or more of the following events (regardless
of whether any other reason, other than Cause as hereinabove provided, for such
termination exists or has occurred, including, without limitation, other
employment):

                           (i) Failure to elect or reelect or otherwise to
         maintain the Executive in the office or the position, or a
         substantially equivalent office or position, of or with the Company
         and/or a Subsidiary (or any successor thereto by operation of law of or
         otherwise), as the case may be, which the Executive held immediately
         prior to a Change in Control, or the removal of the Executive as a
         Director of the Company and/or a Subsidiary (or any successor thereto)
         if the Executive shall have been a Director of the Company and/or a
         Subsidiary immediately prior to the Change in Control;

                           (ii) (A) A significant adverse change in the nature
         or scope of the authorities, powers, functions, responsibilities or
         duties attached to the position with the Company and any Subsidiary
         which the Executive held immediately prior to the Change in Control,
         (B) a reduction in the aggregate of the Executive's annual base salary
         rate as in effect from time to time ("Base Pay") and annual bonus,
         incentive or other payment of compensation, in addition to Base Pay,
         made or to be made in regard to services rendered in any year or other
         period pursuant to any bonus, incentive, profit-sharing, performance,
         discretionary pay or similar agreement, policy, plan, program or
         arrangement (whether or not funded) of the Company or a Subsidiary, or
         any successor thereto (collectively "Incentive Pay") received from the
         Company and any Subsidiary, or (C) the termination or denial of the
         Executive's rights to the perquisites, benefits and service credit for
         benefits as provided under any and all employee retirement income and
         welfare benefit policies, plans, programs or arrangements in which
         Executive is entitled to participate, including, without limitation,
         any stock option, performance share, performance unit, stock purchase,
         stock appreciation, savings, pension, supplemental executive
         retirement, or other retirement income or welfare benefit, deferred
         compensation, incentive compensation, group or other life, health,
         medical/hospital or other insurance (whether funded by actual insurance
         or self-insured by the Company or a Subsidiary), disability, salary
         continuation, expense reimbursement and other employee benefit
         policies, plans, programs or arrangements that may now exist or any
         equivalent successor policies, plans, programs or arrangements that may
         be adopted hereafter by the Company or a Subsidiary, providing
         perquisites, benefits and service credit for benefits at least as great
         in the aggregate as are payable thereunder prior to a Change in Control
         (collectively, "Employee Benefits") or a reduction in the scope or
         value thereof, any of which is not remedied by the Company


                                        4
<PAGE>   5
         within 10 calendar days after receipt by the Company of written notice
         from the Executive of such change, reduction or termination, as the
         case may be;

                           (iii) A determination by the Executive (which
         determination will be conclusive and binding upon the parties hereto
         provided it has been made in good faith and in all events will be
         presumed to have been made in good faith unless otherwise shown by the
         Company by clear and convincing evidence) that a change in
         circumstances has occurred following a Change in Control, including,
         without limitation, a change in the scope of the business or other
         activities for which the Executive was responsible immediately prior to
         the Change in Control, which has rendered the Executive substantially
         unable to carry out, has substantially hindered Executive's performance
         of, or has caused Executive to suffer a substantial reduction in, any
         of the authorities, powers, functions, responsibilities or duties
         attached to the position held by the Executive immediately prior to the
         Change in Control, which situation is not remedied within 10 calendar
         days after written notice to the Company from the Executive of such
         determination;

                           (iv) The liquidation, dissolution, merger,
         consolidation or reorganization of the Company or transfer of all or
         substantially all of its business and/or assets, unless the successor
         or successors (by liquidation, merger, consolidation, reorganization,
         transfer or otherwise) to which all or substantially all of its
         business and/or assets have been transferred (by operation of law or
         otherwise) assumed all duties and obligations of the Company under this
         Agreement pursuant to Section 11(a);

                           (v) The Company relocates its principal executive
         offices (if such offices are the principal location of Executive's
         work), or requires the Executive to have his principal location of work
         changed, to any location that, in either case, is in excess of 50 miles
         from the location thereof immediately prior to the Change in Control,
         or requires the Executive to travel away from his office in the course
         of discharging his responsibilities or duties hereunder at least 20%
         more (in terms of aggregate days in any calendar year or in any
         calendar quarter when annualized for purposes of comparison to any
         prior year) than was required of Executive in any of the three full
         years immediately prior to the Change in Control without, in either
         case, his prior written consent; or

                           (vi) Without limiting the generality or effect of the
         foregoing, any material breach of this Agreement by the Company or any
         successor thereto which is not remedied by the Company within 10
         calendar days after receipt by the Company of written notice from the
         Executive of such breach.

                  [(c) Notwithstanding anything contained in this Agreement to
the contrary, in the event of a Change in Control, other than a Change of
Control satisfying the provisions of Section 3(b)(iv), the Executive may
terminate employment with the Company and any Subsidiary for any reason, or
without reason, during the 30-day period immediately following the first
anniversary of the first occurrence of a Change in Control with the right to
severance compensation as provided in Section 4.]

                  (d) A termination by the Company pursuant to Section 3(a) or
by the Executive pursuant to Section 3(b) or Section 3(c) will not affect any
rights that the Executive may have


                                        5
<PAGE>   6
pursuant to any agreement, policy, plan, program or arrangement of the Company
or Subsidiary providing Employee Benefits, which rights shall be governed by the
terms thereof, which rights shall, during the Severance Period, be superseded by
this Agreement.

                  4. Severance Compensation. (a) If, following the occurrence of
a Change in Control, the Company or Subsidiary terminates the Executive's
employment during the Severance Period other than pursuant to Section 3(a), or
if the Executive terminates his employment pursuant to Section 3(b) or Section
3(c), the Company will pay to the Executive the amounts described in Annex A
within five business days after the date on which the Executive's employment is
terminated (the effective date of which shall be the date of termination, or
such other date that may be specified by the Executive if the termination is
pursuant to Section 3(b) or Section 3(c)) (the "Termination Date") and will
continue to provide to the Executive the benefits described on Annex A for the
periods described therein.

                  (b) Without limiting the rights of the Executive at law or in
equity, if the Company fails to make any payment or provide any benefit required
to be made or provided hereunder on a timely basis, the Company will pay
interest on the amount or value thereof at an annualized rate of interest equal
to the so-called composite "prime rate" as quoted from time to time during the
relevant period in the Midwest Edition of The Wall Street Journal, plus 1.0%.
Such interest will be payable as it accrues on demand. Any change in such prime
rate will be effective on and as of the date of such change.

                  (c) Notwithstanding any provision of this Agreement to the
contrary, the parties' respective rights and obligations under this Section 4
and under Sections 5, 7, 8 and the last sentence of Section 9 will survive any
termination or expiration of this Agreement or the termination of the
Executive's employment following a Change in Control for any reason whatsoever.

                  (d) Unless otherwise expressly provided by the applicable
plan, program or agreement, after the occurrence of a Change in Control, the
Company shall pay in cash to the Executive a lump sum amount equal to the value
of any annual bonus or long-term incentive pay (including, without limitation,
incentive-based annual cash bonuses and performance units, but not including any
equity-based compensation or compensation provided under a qualified plan)
earned or accrued with respect to the Executive's service during the performance
period or periods that includes the date on which the Change in Control
occurred, disregarding any applicable vesting requirements; provided that such
amount shall be calculated at the plan target or payout rate, but prorated to
base payment only on the portion of the Executive's service that had elapsed
during the applicable performance period. Such payment shall take into account
service rendered through the payment date and shall be made at the earlier of
(i) the date prescribed for payment pursuant to the applicable plan, program or
agreement and (ii) within five business days after the Termination Date.

                  (e) Pursuant to the terms and conditions of any applicable
plan, program or agreement, upon the occurrence of a Change of Control, all
equity incentive awards held by the Executive shall become vested and
exercisable in accordance with such plan, program or agreement.


                                        6

                  5. Certain Additional Payments by the Company. (a) Anything in
this Agreement to the contrary notwithstanding, in the event that this Agreement
shall become operative and it shall be determined (as hereafter provided) that
any payment (other than the Gross-Up payments provided for in this Section 5) or
distribution by the Company or any of its affiliates to or for the benefit of
the Executive, whether paid or payable or distributed or distributable pursuant
to the terms of this Agreement or otherwise pursuant to or by reason of any
other agreement, policy, plan, program or arrangement, including, without
limitation, any stock option, performance share, performance unit, stock
appreciation right or similar right, or the lapse or termination of any
restriction on or the vesting or exercisability of any of the foregoing (a
"Payment"), would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code") (or any successor
provision thereto) by reason of being considered "contingent on a change in
ownership or control" of the Company, within the meaning of Section 280G of the
Code (or any successor provision thereto) or to any similar tax imposed by state
or local law, or any interest or penalties with respect to such tax (such tax or
taxes, together with any such interest and penalties, being hereafter
collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment or payments (collectively, a "Gross-Up
Payment"); provided, however, that no Gross-up Payment shall be made with
respect to the Excise Tax, if any, attributable to (i) any incentive stock
option, as defined by Section 422 of the Code ("ISO") granted prior to the
execution of this Agreement, or (ii) any stock appreciation or similar right,
whether or not limited, granted in tandem with any ISO described in clause (i).
The Gross-Up Payment shall be in an amount such that, after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, the
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payment.

                  (b) Subject to the provisions of Section 5(f), all
determinations required to be made under this Section 5, including whether an
Excise Tax is payable by the Executive and the amount of such Excise Tax and
whether a Gross-Up Payment is required to be paid by the Company to the
Executive and the amount of such Gross-Up Payment, if any, shall be made by a
nationally recognized accounting firm (the "Accounting Firm") selected by the
Executive in his sole discretion. The Executive shall direct the Accounting Firm
to submit its determination and detailed supporting calculations to both the
Company and the Executive within 30 calendar days after the Termination Date, if
applicable, and any such other time or times as may be requested by the Company
or the Executive. If the Accounting Firm determines that any Excise Tax is
payable by the Executive, the Company shall pay the required Gross-Up Payment to
the Executive within five business days after receipt of such determination and
calculations with respect to any Payment to the Executive. If the Accounting
Firm determines that no Excise Tax is payable by the Executive, it shall, at the
same time as it makes such determination, furnish the Company and the Executive
an opinion that the Executive has substantial authority not to report any Excise
Tax on his federal, state or local income or other tax return. As a result of
the uncertainty in the application of Section 4999 of the Code (or any successor
provision thereto) and the possibility of similar uncertainty regarding
applicable state or local tax law at the time of any determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made (an "Underpayment"),
consistent with the calculations required to be made hereunder. In the event
that the Company exhausts or fails to pursue its remedies pursuant to Section
5(f) and the Executive thereafter is required to make a payment of any Excise
Tax, the Executive shall direct the Accounting Firm to determine the amount of
the Underpayment that has occurred and to submit its determination and detailed


                                        7
<PAGE>   8
supporting calculations to both the Company and the Executive as promptly as
possible. Any such Underpayment shall be promptly paid by the Company to, or for
the benefit of, the Executive within five business days after receipt of such
determination and calculations.

                  (c) The Company and the Executive shall each provide the
Accounting Firm access to and copies of any books, records and documents in the
possession of the Company or the Executive, as the case may be, reasonably
requested by the Accounting Firm, and otherwise cooperate with the Accounting
Firm in connection with the preparation and issuance of the determinations and
calculations contemplated by Section 5(b). Any determination by the Accounting
Firm as to the amount of the Gross-Up Payment shall be binding upon the Company
and the Executive.

                  (d) The federal, state and local income or other tax returns
filed by the Executive shall be prepared and filed on a consistent basis with
the determination of the Accounting Firm with respect to the Excise Tax payable
by the Executive. The Executive shall make proper payment of the amount of any
Excise Tax, and at the request of the Company, provide to the Company true and
correct copies (with any amendments) of his federal income tax return as filed
with the Internal Revenue Service and corresponding state and local tax returns,
if relevant, as filed with the applicable taxing authority, and such other
documents reasonably requested by the Company, evidencing such payment. If prior
to the filing of the Executive's federal income tax return, or corresponding
state or local tax return, if relevant, the Accounting Firm determines that the
amount of the Gross-Up Payment should be reduced, the Executive shall within
five business days pay to the Company the amount of such reduction.

                  (e) The fees and expenses of the Accounting Firm for its
services in connection with the determinations and calculations contemplated by
Section 5(b) shall be borne by the Company. If such fees and expenses are
initially paid by the Executive, the Company shall reimburse the Executive the
full amount of such fees and expenses within five business days after receipt
from the Executive of a statement therefor and reasonable evidence of his
payment thereof.

                  (f) The Executive shall notify the Company in writing of any
claim by the Internal Revenue Service or any other taxing authority that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such
notification shall be given as promptly as practicable but no later than 10
business days after the Executive actually receives notice of such claim and the
Executive shall further apprise the Company of the nature of such claim and the
date on which such claim is requested to be paid (in each case, to the extent
known by the Executive). The Executive shall not pay such claim prior to the
earlier of (i) the expiration of the 30-calendar-day period following the date
on which he gives such notice to the Company and (ii) the date that any payment
of amount with respect to such claim is due. If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive shall:

                           (i) provide the Company with any written records or
                  documents in his possession relating to such claim reasonably
                  requested by the Company;

                           (ii) take such action in connection with contesting
                  such claim as the Company shall reasonably request in writing
                  from time to time, including, without


                                        8
<PAGE>   9
                  limitation, accepting legal representation with respect to
                  such claim by an attorney competent in respect of the subject
                  matter and reasonably selected by the Company;

                           (iii) cooperate with the Company in good faith in
                  order effectively to contest such claim; and

                           (iv) permit the Company to participate in any
                  proceedings relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including interest and penalties) incurred in connection with such
contest and shall indemnify and hold harmless the Executive, on an after-tax
basis, for and against any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limiting the foregoing provisions of this
Section 5(f), the Company shall control all proceedings taken in connection with
the contest of any claim contemplated by this Section 5(f) and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim
(provided, however, that the Executive may participate therein at his own cost
and expense) and may, at its option, either direct the Executive to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs the Executive to pay the tax claimed and sue for a refund, the
Company shall advance the amount of such payment to the Executive on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income or other tax, including interest
or penalties with respect thereto, imposed with respect to such advance; and
provided further, however, that any extension of the statute of limitations
relating to payment of taxes for the taxable year of the Executive with respect
to which the contested amount is claimed to be due is limited solely to such
contested amount. Furthermore, the Company's control of any such contested claim
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

                  (g) If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 5(f), the Executive receives any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(f)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
any taxes applicable thereto). If, after the receipt by the Executive of an
amount advanced by the Company pursuant to Section 5(f), a determination is made
that the Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify the Executive in writing of its intent to
contest such denial or refund prior to the expiration of 30 calendar days after
such determination, then such advance shall be forgiven and shall not be
required to be repaid and the amount of any such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid by the
Company to the Executive pursuant to this Section 5.


                                        9
<PAGE>   10
                  6. No Mitigation Obligation. The Company hereby acknowledges
that it will be difficult and may be impossible for the Executive to find
reasonably comparable employment following the Termination Date. Accordingly,
the payment of the severance compensation by the Company to the Executive in
accordance with the terms of this Agreement is hereby acknowledged by the
Company to be reasonable, and the Executive will not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other employment
or otherwise, nor will any profits, income, earnings or other benefits from any
source whatsoever create any mitigation, offset, reduction or any other
obligation on the part of the Executive hereunder or otherwise, except as
expressly provided in the last sentence of Paragraph 2 set forth on Annex A.

                  7. Legal Fees and Expenses. It is the intent of the Company
that the Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement by litigation or otherwise because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if it should appear to the Executive that
the Company has failed to comply with any of its obligations under this
Agreement or in the event that the Company or any other person takes or
threatens to take any action to declare this Agreement void or unenforceable, or
institutes any litigation or other action or proceeding designed to deny, or to
recover from, the Executive the benefits provided or intended to be provided to
the Executive hereunder, the Company irrevocably authorizes the Executive from
time to time to retain counsel of Executive's choice, at the expense of the
Company as hereafter provided, to advise and represent the Executive in
connection with any such interpretation, enforcement or defense, including,
without limitation, the initiation or defense of any litigation or other legal
action, whether by or against the Company or any Director, officer, stockholder
or other person affiliated with the Company, in any jurisdiction.
Notwithstanding any existing or prior attorney-client relationship between the
Company and such counsel, the Company irrevocably consents to the Executive's
entering into an attorney-client relationship with such counsel, and in that
connection the Company and the Executive agree that a confidential relationship
shall exist between the Executive and such counsel. Without respect to whether
the Executive prevails, in whole or in part, in connection with any of the
foregoing, the Company will pay and be solely financially responsible for any
and all attorneys' and related fees and expenses incurred by the Executive in
connection with any of the foregoing; provided that, in regard to such matters,
the Executive has not acted in bad faith or with no colorable claim of success.

                  8. Confidentiality. (a) During the Term, the Company agrees
that it will disclose to Executive its confidential or proprietary information
(as defined in this Section 8) to the extent necessary for Executive to carry
out his obligations to the Company. The Executive hereby covenants and agrees
that he will not, without the prior written consent of the Company, during the
Term or thereafter disclose to any person not employed by the Company, or use in
connection with engaging in competition with the Company, any confidential or
proprietary information of the Company. For purposes of this Agreement, the term
"confidential or proprietary information" will include all information of any
nature and in any form that is owned by the Company and that is not publicly
available (other than by Executive's breach of this Section 8) or generally
known to persons engaged in businesses similar or related to those of the
Company. Confidential or proprietary information will include, without
limitation, the Company's financial matters, customers, employees, industry
contracts, strategic business plans, product development (or other proprietary
product data), marketing plans, and all other secrets


                                       10
<PAGE>   11
and all other information of a confidential or proprietary nature. For purposes
of the preceding two sentences, the term "Company" will also include any
Subsidiary (collectively, the "Restricted Group"). The foregoing obligations
imposed by this Section 8 will not apply (i) during the Term, in the course of
the business of, and for the benefit of, the Company, (ii) if such confidential
or proprietary information will have become, through no fault of the Executive,
generally known to the public or (iii) if the Executive is required by law to
make disclosure (after giving the Company notice and an opportunity to contest
such requirement).

                  (b) Executive and the Company agree that the covenants
contained in this Section 8 are reasonable under the circumstances, and further
agree that if in the opinion of any court of competent jurisdiction any such
covenant is not reasonable in any respect, such court will have the right, power
and authority to excise or modify any provision or provisions of such covenants
as to the court will appear not reasonable and to enforce the remainder of the
covenants as so amended. Executive acknowledges and agrees that the remedy at
law available to the Company for breach of any of his obligations under this
Section 8 would be inadequate and that damages flowing from such a breach may
not readily be susceptible to being measured in monetary terms. Accordingly,
Executive acknowledges, consents and agrees that, in addition to any other
rights or remedies that the Company may have at law, in equity or under this
Agreement, upon adequate proof of his violation of any such provision of this
Agreement, the Company will be entitled to immediate injunctive relief and may
obtain a temporary order restraining any threatened or further breach, without
the necessity of proof of actual damage.

                  9. Employment Rights. Nothing expressed or implied in this
Agreement will create any right or duty on the part of the Company or the
Executive to have the Executive remain in the employment of the Company or any
Subsidiary prior to or following any Change in Control. Any termination of
employment of the Executive or the removal of the Executive from the office or
position in the Company or any Subsidiary that occurs (i) not more than 90 days
prior to the date on which a Change in Control occurs, and (ii) following the
commencement of any discussion with a third person that ultimately results in a
Change in Control, shall be deemed to be a termination or removal of the
Executive after a Change in Control for purposes of this Agreement.

                  10. Withholding of Taxes. The Company may withhold from any
amounts payable under this Agreement all federal, state, city or other taxes as
the Company is required to withhold pursuant to any applicable law, regulation
or ruling.

                  11. Successors and Binding Agreement. (a) The Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation, reorganization or otherwise) to all or substantially all of the
business or assets of the Company, by agreement in form and substance reasonably
satisfactory to the Executive, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent the Company would be
required to perform if no such succession had taken place. This Agreement will
be binding upon and inure to the benefit of the Company and any successor to the
Company, including without limitation any persons acquiring directly or
indirectly all or substantially all of the business or assets of the Company
whether by purchase, merger, consolidation, reorganization or otherwise (and
such successor shall thereafter be deemed the "Company" for the purposes of this
Agreement), but will not otherwise be assignable, transferable or delegable by
the Company.

                                       11
<PAGE>   12
                  (b) This Agreement will inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees and legatees.

                  (c) This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as
expressly provided in Sections 11(a) and 11(b). Without limiting the generality
or effect of the foregoing, the Executive's right to receive payments hereunder
will not be assignable, transferable or delegable, whether by pledge, creation
of a security interest, or otherwise, other than by a transfer by Executive's
will or by the laws of descent and distribution and, in the event of any
attempted assignment or transfer contrary to this Section 11(c), the Company
shall have no liability to pay any amount so attempted to be assigned,
transferred or delegated.

                  12. Notices. For all purposes of this Agreement, all
communications, including, without limitation, notices, consents, requests or
approvals, required or permitted to be given hereunder will be in writing and
will be deemed to have been duly given when hand delivered or dispatched by
electronic facsimile transmission (with receipt thereof orally confirmed), or
five business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid, or three business
days after having been sent by a nationally recognized overnight courier service
addressed to the Company (to the attention of the Secretary of the Company) at
its principal executive office and to the Executive at his principal residence,
or to such other address as any party may have furnished to the other in writing
and in accordance herewith, except that notices of changes of address shall be
effective only upon receipt.

                  13. Governing Law. The validity, interpretation, construction
and performance of this Agreement will be governed by and construed in
accordance with the substantive laws of the State of Delaware, without giving
effect to the principles of conflict of laws of such State.

                  14. Validity. (a) If any provision of this Agreement or the
application of any provision hereof to any person or circumstances is held
invalid, unenforceable or otherwise illegal, the remainder of this Agreement and
the application of such provision to any other person or circumstances will not
be affected, and the provision so held to be invalid, unenforceable or otherwise

                    SEPARATION AGREEMENT AND GENERAL RELEASE
                    ----------------------------------------


1.       I, JON D. SCHOELER ("Employee"), accept the termination of my
         employment from Gliatech Inc. ("Gliatech") effective 12/31/99 (the
         "Separation Date"), in accordance with the terms of this Agreement. In
         accepting the consideration stated in Paragraph 2 below, Employee
         hereby releases Gliatech and each of its successors, assigns,
         shareholders, officers, directors, employees, agents and counsel from
         any and all actions, suits, claims, and demands of any kind, in law or
         equity, that Employee ever had or now has, by reason of any event,
         claim, matter, cause or thing, and particularly any claim relating in
         any way to Employee's employment or the termination of Employee's
         employment with Gliatech, including without limitation any claim under
         the Age Discrimination in Employment Act, any claim arising under any
         federal, state, or local law, and any claim under common law.

2.       In full consideration of Employee signing this Separation Agreement and
         General Release ("Agreement") and the covenants contained herein,
         Gliatech agrees to the following:

         A.       Employee shall be paid a total of ONE HUNDRED SEVENTY THOUSAND
                  DOLLARS ($170,000.00) (representing ONE (1) YEAR of severance
                  pay) (the "Severance Amount"), less all applicable withholding
                  taxes, payable in a lump sum on or before January 31, 2000,
                  plus 1999 bonus of 10% of salary ($17,000.00).

         B.       Employee shall be paid for credited but unused vacation time
                  determined as of the Separation Date, with such payment to be
                  made within fifteen days of the Separation Date.

         C.       Employee shall be entitled to continuation of medical and
                  dental coverage at Employee's present level of benefits as
                  provided under COBRA, for the period of THREE (3) MONTHS
                  following separation date.

         D.       Gliatech will provide Employee with an employee outplacement
                  service with Drake Beam Morin for a period of SIX (6) MONTHS
                  following Employee's termination with Gliatech.

3.       Gliatech's obligations hereunder shall terminate in the event Employee
         breaches any of Employee's obligations under this Agreement.

4.       Employee agrees that Employee will maintain the confidentiality of
         confidential information Employee has received by virtue of Employee's
         employment with Gliatech and will not use such information or disclose
         it to any person other than


<PAGE>   2
         Gliatech. For purposes of this Agreement, confidential information is
         information which Gliatech endeavors to keep proprietary, including
         without limitation customer lists, employee lists, rate schedules,
         underwriting information, the terms of contracts and policies,
         marketing plans, program designs, trade secrets, proprietary
         information, and any information provided by a third-party to Gliatech
         in confidence. Employee agrees that, upon Employee's separation,
         Employee will return to Gliatech any records in Employee's possession
         containing confidential information of Gliatech and all records which
         are the property of Gliatech.

5.       Employee acknowledges that the consideration set forth in Paragraph 2
         is solely in exchange for the promises in this Agreement and is an
         amount in excess of any amount to which he is entitled under any law,
         regulation or company policy, procedure or practice. Employee further
         acknowledges that such payment does not constitute an admission by
         Gliatech or the other released parties of liability or of violation of
         any applicable law or regulation, all of whom deny any liability or
         alleged violation and state that payment has been made solely for the
         purpose of compromising any and all actual or potential claims of
         Employee.

6.       Employee may revoke and cancel this Agreement in writing at any time
         within seven days after Employee's execution of this Agreement by
         providing notice of revocation to GLIATECH INC., ATTENTION: MONICA
         THAYER, AT 23420 COMMERCE PARK ROAD, BEACHWOOD, OH 44122. For
         revocation to be effective, written notice must be received by
         REGISTERED MAIL no later than the close of business on the seventh day
         after Employee signs this Agreement. If Employee does so revoke, this
         Agreement will be null and void and Gliatech shall have no obligation
         to make the payments provided in Paragraph 2. This Agreement shall not
         become effective and enforceable until after the expiration of the
         seven-day revocation period; after such time, if there has been no
         revocation, this Agreement shall be fully effective and enforceable.

7.       Employee agrees that he has had the opportunity to consult counsel,
         that no deadline of less than 21-days has been imposed upon him to
         execute this Agreement, and that Employee has had time to read and
         consider this Agreement before signing it.

8.       Employee has read and understands all of the terms of this Agreement
         and signs this Agreement in exchange for the consideration to be given
         to Employee. Neither Gliatech nor any of its agents, representatives or
         employees has made any representations to Employee concerning the terms
         or effects of this Agreement other than those contained in this
         Agreement.

9.       This Agreement shall be governed and interpreted in accordance with the
         laws of the State of Ohio.


IN WITNESS WHEREOF, the parties have executed this Agreement this 7 day of
December, 1999.

                    SEPARATION AGREEMENT AND GENERAL RELEASE
                    ----------------------------------------


1.       I, JOHN A. REDMOND ("Employee"), accept the termination of my

         the consideration and promise stated in Paragraphs 2 and 9 below,
         Employee hereby releases Gliatech and each of its successors, assigns,
         shareholders, officers, directors, employees, agents and counsel from
         any and all actions, suits, claims and demands of any kind other than
         any claims arising under a breach of this agreement, in law or equity,
         that Employee ever had or now has, by reason of any event, claim,
         matter, cause or thing, and particularly any claim relating in any way
         to Employee's employment or the termination of Employee's employment
         with Gliatech, including without limitation any claim under the Age
         Discrimination in Employment Act, any claim arising under any federal,
         state, or local law, and any claim under common law.

2.       In full consideration of Employee signing this Agreement and the
         covenants contained herein, Gliatech agrees to the following:

             A.    Employee shall be paid a total of TWO HUNDRED THOUSAND
                   DOLLARS ($200,000.00) (representing ONE 1 YEAR of
                   severance pay) (the "Severance Amount"), less all applicable
                   withholding taxes, payable in a lump sum on or before
                   January 15, 2000.

             B.    Employee shall be paid for credited but unused vacation time

                   months from the Separation Date, Gliatech will continue to
                   pay Employee's full premium for such coverage.

         an amount in excess of any amount to which he is entitled under any
         law, regulation or company policy, procedure or practice. Employee
         further acknowledges that such payment does not constitute an admission
         by Gliatech or the other released parties of liability or of violation
         of any applicable law or regulation, all of whom deny any liability or
         alleged violation and state that payment has been made solely for the
         purpose of compromising any and all actual or potential claims of
         Employee.

6.       Employee may revoke and cancel this Agreement in writing at any time
         within seven days after Employee's execution of this Agreement by

         revocation to be effective, written notice must be received by
         REGISTERED MAIL no later than the close of business on the seventh day
         after Employee signs this Agreement. If Employee does so revoke, this
         Agreement will be null and void and Gliatech shall have no obligation
         to make the payments or to undertake the obligations provided in
         Paragraphs 2 and 9. This Agreement shall not become effective and
         enforceable until after the expiration of the seven-day revocation
         period; after such time, if there has been no revocation, this
         Agreement shall be fully effective and enforceable.

7.       Employee agrees that he has had the opportunity to consult counsel,
         that no deadline of less than 21-days has been imposed upon him to
         execute this Agreement, and that Employee has had time to read and
         consider this Agreement before signing it.

8.       Employee has read and understands all of the terms of this Agreement
         and signs this Agreement in exchange for the consideration to be given
         to Employee. Neither Gliatech nor any of its agents, representatives or
         employees has made any representations to Employee concerning the terms
         or effects of this Agreement other than those contained in this
         Agreement.
