PART I

ITEM 1. BUSINESS

GENERAL

American Shared Hospital Services ("ASHS" and, together with its
subsidiaries, the "Company") currently provides Gamma Knife stereotactic
radiosurgery services to eight medical centers in seven states. The Company
provides these services through its 81% indirect interest in GK Financing, LLC,
a California limited liability company ("GKF"). The remaining 19% of GKF is
owned by GKV Investments, Inc., a wholly owned U.S. subsidiary of Elekta AG, a
Swedish company ("Elekta"). Elekta is the manufacturer of the Leksell Gamma
Knife (the "Gamma Knife"). GKF is a non-exclusive provider of alternative
financing services for Elekta. Gamma Knife services accounted for almost 100% of
the Company's revenues in 1999.

At present, the Company is developing a business plan for "The Operating
Room for the 21st Century" (sm) ("OR21" (sm)). The Company also is exploring
Internet-related business opportunities that relate strategically and
operationally to its existing and developing lines of business. Neither OR21 nor
the Internet-related businesses are expected to generate significant revenues
within the next twelve months. The Company's former insurance services business
did not contribute significant revenues and was discontinued during second
quarter 1999.

During November 1998, the Company sold its diagnostic imaging business to
affiliates of Alliance Imaging, Inc. (the "Purchaser") for $13,552,000 in cash
and the assumption by the Purchaser of substantially all of the liabilities of
the diagnostic imaging business, including approximately $27.1 million in debt
and other liabilities. Prior to that sale, the Company provided Magnetic
Resonance Imaging ("MRI"), Computed Axial Tomography ("CT"), Ultrasound, Nuclear
Medicine and Cardiac Catheterization Laboratory services to approximately 190
customers in 22 states. The diagnostic imaging business provided approximately
88% and 94%, respectively, of the Company's revenues for the years ended
December 31, 1998 and 1997.

The Company was incorporated in the state of California in 1983 and its
predecessor, Ernest A. Bates, M.D., Ltd. (d/b/a American Shared Hospital
Services), a California limited partnership, was formed in June 1980.

GAMMA KNIFE OPERATIONS

Gamma Knife stereotactic radiosurgery, a non-invasive procedure, is an
alternative to conventional brain surgery or can be an adjunct to conventional
brain surgery. Compared to conventional surgery, Gamma Knife surgery usually
involves shorter patient hospitalization, lower risk of complications and can be
provided at a lower cost. Typically, Gamma Knife patients resume their normal
activities one or two days after treatment. The Gamma Knife treats the patient
with 201 single doses of gamma rays that are focused with great precision on
small, well circumscribed and critically located structures in the brain. The
Gamma Knife delivers the concentrated dose of gamma rays from 201 sources of
Cobalt 60 housed in the Gamma Knife.

The 201 Cobalt 60 sources converge at the target area and deliver a dose
that is high enough to destroy the diseased tissue without damaging surrounding
healthy tissue.

The Gamma Knife treats selected benign brain tumors (i.e. meningiomas,
pituitary and acoustic neuromas, craniopharyngiomas), malignant tumors (i.e.
gliomas, nasopharyngeal carcinomas, ocular meningiomas and solitary and multiple
metastatic tumors), arteriovenous malformations and trigeminal neuralgia (facial
pain). Research is being conducted in the treatment of Parkinson's Disease,
epilepsy, and other functional disorders.

There currently are 55 Gamma Knife units operating at 54 sites in the
United States and approximately 135 units worldwide. As of December 31, 1999,
approximately 135,000 procedures had been performed worldwide. An estimated
percentage breakdown of these Gamma Knife procedures performed in the U.S. by
indications treated are as follows: malignant (40%) and benign (32%) tumors,
vascular disorders (17%) and functional disorders (11%).

The Company currently has eight (8) Gamma Knife units operating at eight
(8) sites in the United States. In addition, the Company has signed agreements
with four (4) more hospitals that are currently under development or
construction, plus two (2) signed contracts that are subject to state regulatory
approval. The

2
3

Company's first Gamma Knife commenced operation in September 1991. The Company's
Gamma Knife units had performed approximately 3,300 procedures through December
31, 1999.

Gamma Knife revenues for the Company during the five (5) years ended
December 31, 1999, and the percentage of total revenues of the Company
represented by the Gamma Knife for each of the last five years are set forth
below:



YEAR ENDED TOTAL GAMMA KNIFE GAMMA KNIFE/
DECEMBER 31, REVENUES (IN THOUSANDS) TOTAL REVENUES
------------ ----------------------- --------------

1999.................................... $7,151 99.9%
1998.................................... $4,156 11.8%
1997.................................... $2,384 6.4%
1996.................................... $2,030 5.5%
1995.................................... $1,325 3.9%


The Company conducts its Gamma Knife business through its 81% indirect
interest in GKF. The remaining 19% interest is indirectly owned by Elekta. GKF,
a limited liability company, was formed in October 1995. GKF is managed by its
policy committee. The policy committee is composed of one representative from
the Company, Ernest A. Bates, M.D., and one representative from Elekta. The
policy committee sets the operating policy for GKF. The policy committee may act
only with the unanimous approval of all of its members. The policy committee
selects a manager to handle GKF's daily operations. Craig K. Tagawa, Chief
Executive Officer of GKF and Chief Operating and Financial Officer of the
Company, serves as GKF's manager.

GKF profits and/or losses and any cash distributions are allocated based on
membership interests. GKF's Operating Agreement requires that it have a cash
reserve of at least $50,000 prior to cash distributions to its members. From
inception to December 31, 1999, GKF had distributed $1,558,000 to the Company.

RISKS OF GAMMA KNIFE BUSINESS

There are significant risks involved in the Company's Gamma Knife business,
including the following:

- Each Gamma Knife unit requires a substantial capital investment. The
Company's cost for a Gamma Knife unit historically has been approximately
$2,750,000. In some cases, the Company contributes additional funds for
capital costs and/or annual operating costs such as marketing. Due to the
structure of its contracts with medical centers, there can be no
assurance that these costs will be fully recovered or that the Company
will earn a satisfactory return on its investment.

- There is a limited market for the Gamma Knife. Due to the substantial
costs of acquiring a Gamma Knife, the Company must identify medical
centers that possess neurosurgery and oncology departments capable of
performing a large number of Gamma Knife procedures. The Company has
identified approximately 200 such medical centers in the United States as
potential future sites. There currently are 55 operating Gamma Knife
units in the United States, eight (8) of which are Company-operated
units. There can be no assurance that the Company will be successful in
placing additional units at a significant number of sites in the future.

- There currently are four companies (in addition to the Company) that
supply the Gamma Knife to potential customers. One of the four companies
purchased one Gamma Knife within the last twelve months. The Company does
not currently have an exclusive relationship with Elekta and has lost
sales in the past to customers that choose to purchase a Gamma Knife
directly from Elekta. In addition, the Company may continue to lose sales
in the future to such customers and may also lose sales to competitors of
the Company. There can be no assurance that the Company will be able to
successfully compete against others to place units in the future.

- There are several methods of radiosurgery (including the modified linear
accelerator) as well as conventional neurosurgery that compete against
the Gamma Knife. Currently, there are approximately 200 medical centers
in the United States with modified linear accelerators. Each of the
medical centers targeted by the Company could decide to acquire another
radiosurgery modality instead of a Gamma Knife. In addition,
neurosurgeons who are primarily responsible for referring patients for
Gamma Knife surgery may not be willing to make such referrals for various
reasons, instead opting for invasive

3
4

surgery. There can be no assurance that the Company will be able to
secure a sufficient number of sites or Gamma Knife procedures to attain
profitability and growth.

- The amount reimbursed to medical centers for each Gamma Knife treatment
may decline in the future. The reimbursement decrease may come from
federally mandated programs (i.e. Medicare and Medicaid) and other third
party payor groups. A significant amount of the Company's existing
contracts are reimbursed by the medical center to the Company on a
fee-for-service basis. The primary risk to the Company under this type of
contract is that actual volumes of procedures could be less than
projected. The Company also has two contracts where it receives revenues
based directly on the amount of reimbursement received for procedures
performed. Revenues under those contracts and any future contracts with
revenue based directly on reimbursement amounts will be impacted by any
reimbursement rate change. Some of the Company's future contracts for
Gamma Knife services may have revenues based on such reimbursement rates
instead of a fee-for-service basis. There can be no assurance that future
changes in healthcare regulations and reimbursement rates will not
adversely affect the Company's Gamma Knife revenues.

- As with other highly sophisticated medical equipment, there is constant
change and innovation in the market. New and improved medical equipment
can be introduced that could make the Gamma Knife technology obsolete and
that would make its operation uneconomic. During the current year, Elekta
is introducing an upgraded Gamma Knife which is expected to cost
approximately $3.4 million plus applicable tax and duties. This upgrade
is anticipated to automate the patient positioning process and therefore
involve less health care provider intervention. Seven (7) of the
Company's existing Gamma Knife units are upgradeable. The cost to upgrade
existing units to the new model is estimated to be up to $900,000.

CUSTOMERS

The Company's current business is the outsourcing of Gamma Knife
stereotactic radiosurgery services. The Company typically provides the Gamma
Knife equipment, as well as planning, installation and marketing support
services. Customers usually pay the Company on a fee-per-use basis. The market
for these services primarily consists of major urban medical centers. The Gamma
Knife business is capital intensive. The total cost of a Gamma Knife facility
usually ranges from $3.25 million to $4 million, including equipment, site
construction and installation. The Company's typical, historical costs for
acquisition are approximately $2,750,000 with the medical center paying for site
and installation costs.

REGULATORY APPROVAL


Two additional contracts are signed, pending state regulatory approval.

The Company's second Gamma Knife contract, with the University of Southern
California ("USC") ended in third quarter 1999. The customer exercised its
option to purchase the equipment for its net book value, approximately $1.2
million. Currently, one of the Company's sites now under development is
projected to become operational in second quarter 2000, and two additional
contracts are expected to become operational in fourth quarter 2000. The
Company's contract with Hospital Barra D'Or currently is being renegotiated with
the customer in light of the changes in the Brazilian economic environment. If
the contract cannot be successfully renegotiated, it will be terminated. The
projected operational dates for contracts pending state regulatory approval
cannot currently be estimated.

The Company's fee per use agreement is typically for a ten-year term. The
fixed fee per use reimbursement amount that the Company receives from the
customer is based on the Company's cost to provide the service and the
anticipated volumes of the customer. The contracts signed by the Company
typically call for a fee ranging from $7,500 to $9,500 per procedure. There are
no minimum volume guarantees required of the customer. Typically, GKF is
responsible for providing the Gamma Knife and related ongoing Gamma Knife
equipment expenses (i.e. personal property taxes, insurance, equipment
maintenance) and also helps fund the customer's Gamma Knife marketing.
Typically, the customer is obligated to pay site and installation costs and the
costs of operating the Gamma Knife. Generally, the customer can either renew the
agreement or terminate the agreement upon the termination date of the agreement.
If the customer chooses to terminate the agreement, then GKF removes the
equipment from the medical center.

The Company's revenue sharing agreements are typically for a period of ten
to fifteen years. Instead of receiving a fixed fee, the company receives all or
a percentage of the reimbursement (exclusive of physician fees) received by the
customer less the operating expenses of the Gamma Knife. The Company is at risk
for any reimbursement rate changes for Gamma Knife services by third party
payors. The Company is also at risk if it inefficiently operates its Gamma Knife
services. There are no minimum volume guarantees required of the customer.

Four customers each accounted for more than 10% of the Company's revenues
in 1999: USC, Hoag, STMH and Yale. No single customer accounted for 10% or more
of the Company's total revenues in 1998 or 1997, but each of the five Gamma
Knife customers in 1998 and each of the three Gamma Knife customers in 1997
accounted for more than 10% of the Company's Gamma Knife services revenues in
those years of operation.

MARKETING

At the end of 1999, the Company employed one sales executive. The Company
markets its services through its preferred provider status with Elekta and a
direct sales effort. The major advantages to a health care provider in
contracting with the Company for Gamma Knife services include:

- The medical center avoids the high cost of owning the equipment. By not
acquiring the Gamma Knife unit, the medical center is able to allocate
the funds required to purchase and/or finance the Gamma Knife to other
projects.

- The medical center avoids the risk of Gamma Knife under-utilization. The
Company does not have minimum volume requirements. The medical center
pays the Company only for each Gamma Knife procedure performed on a
patient.

- The medical center transfers the risk of technological obsolescence to
the Company. The medical center and its physicians are not under any
obligation to utilize technologically obsolete equipment.

- The Company provides planning, installation, operating and marketing
assistance and support to its Gamma Knife customers.

FINANCING

The Company's Gamma Knife business is operated through GKF. GKF has funded
its existing Gamma Knife units with loans from a single lender for 100% of the
cost of each Gamma Knife, plus any sales tax, customs and duties. The loans are
fully amortized over an 84-month period. The loans are collateralized by the
Gamma Knife, customer contracts, and accounts receivable and are without
recourse to the Company and Elekta.

GKF currently has loan commitments and has received progress payments from
its primary lender for two (2) of its four (4) Gamma Knife projects under
development. The loan commitments require that GKF have a debt to equity plus
subordinated debt ratio of 6 to 1. GKF currently meets the ratio requirement to
be eligible for funding of the approximately $6,500,000 remaining cash
requirements for its four (4) projects under development.

COMPETITION

Conventional neurosurgery is the primary competitor of Gamma Knife
radiosurgery. Gamma Knife surgery is gaining acceptance as an alternative and/or
adjunct to conventional surgery due to its more favorable morbidity outcomes for
certain procedures as well as its non-invasiveness. Utilization of the Company's
Gamma Knife units is contingent on the acceptance of Gamma Knife radiosurgery by
the customer's neurosurgeons, radiation oncologists and referring physicians. In
addition, the utilization of the Company's Gamma Knife units is impacted by the
proximity of competing Gamma Knife centers and providers using other
radiosurgery modalities.

The Company's ability to contract with additional customers for Gamma Knife
services is dependent on its ability to compete against (i) other companies that
outsource Gamma Knife services, (ii) Elekta, the manufacturer of the Gamma
Knife, and (iii) manufacturers of competing radiosurgery devices (primarily
modified linear accelerators). The Company does not have an exclusive
relationship with Elekta and has lost sales in the past to customers that choose
to purchase a Gamma Knife directly from Elekta. The Company may continue to lose
sales in the future to such customers and may also lose sales to competitors of
the Company.

GOVERNMENT REGULATION

The Company's Gamma Knife services customers receive payments for patient
care from federal government and private insurer reimbursement programs.
Currently, Gamma Knife services are performed primarily on an in-patient basis,
although a significant number are performed on an outpatient basis.

A Prospective Payment System ("PPS") is utilized to reimburse hospitals for
care given to hospital in-patients covered by federally funded reimbursement
programs. Patients are classified into a Diagnosis Related Group ("DRG") in
accordance with the patient's diagnosis, necessary medical procedures and other
factors. Patient reimbursement is limited to a predetermined amount for each
DRG. The reimbursement payment may not necessarily cover the cost of all medical
services actually provided because the payment is predetermined. Effective
October 1, 1997, Gamma Knife services for Medicare hospital in-patients were
reclassified from DRG 1 to either DRG 7 or DRG 8. This reclassification is
estimated to have reduced medical center revenues from the Medicare DRG program
by approximately 30%. In the future, this reduction may lower reimbursement from
other third party payors.

In 1986 and again in 1990, Congress enacted legislation requiring the
Department of Health and Human Services ("DHHS") to develop proposals for a PPS
for hospital outpatient services. DHHS has proposed a new payment system,
Ambulatory Product Classifications ("APC"), which affects all outpatient
services, including those performed in a hospital based or free-standing
facility. APC implementation is anticipated in the third or fourth quarter 2000.

The APC consist of 346 clinically, homogenous classifications or groupings
of codes that are typically used in outpatient billing. Outpatient services will
be bundled with fixed rates of payment determined according to specific regional
and national factors, similar to that of the in-patient PPS. Overall, the system
is expected to reduce payments for select services and encourage the most
efficient use of resources for outpatient care.

6
7

The current APC proposal categorizes radiosurgery under conventional
radiation therapy. Therefore, both procedures would receive the same
reimbursement amounts. This categorization makes no distinction with regard to
the types of resources utilized (e.g. technology) for each procedure
classification. Therefore, regardless of resource consumption and clinical
outcomes, all procedures within a group qualify for equal reimbursement.
Specifically, stereotactic radiosurgery would receive the same reimbursement per
session as conventional radiation therapy. This would result in a significant
reimbursement decrease for Gamma Knife patients covered by Medicare treated on
an outpatient basis. Various groups have informed DHHS of the discrepancies of
these service levels in an attempt to be compensated in line with the intent of
the APC system. It is not the intent of the APC system to compensate providers
similarly for clinically different procedures. The APC reimbursement amount is
not known at this time.

The Company has two contracts where the revenue is directly affected by
changes in payment rates by Medicare and other third party payors. Some of GKF's
future contracts for Gamma Knife services may be on a similar
reimbursement-sensitive basis instead of a fee-for-service basis. As a result of
lower reimbursement rates, profitability from future contracts will be reduced
unless the number of Gamma Knife procedures can be increased or if the costs to
provide Gamma Knife services can be lowered.

The payment of remuneration to induce the referral of health care business
has been a subject of increasing governmental and regulatory focus in recent
years. Section 1128B(b) of the Social Security Act (sometimes referred to as the
"federal anti-kickback statute") provides criminal penalties for individuals or
entities that knowingly and willfully offer, pay, solicit or receive
remuneration in order to induce referrals for items or services for which
payment may be made under the Medicare and Medicaid programs and certain other
government funded programs. The Social Security Act provides authority to the
Office of Inspector General through civil proceedings to exclude an individual
or entity from participation in the Medicare and state health programs if it is
determined any such party has violated Section 1128B(b) of the Social Security
Act. The Company believes that it is in compliance with the federal
anti-kickback statute. Additionally, the Omnibus Budget Reconciliation Act of
1993, often referred to as "Stark II", bans physician self-referrals to
providers of designated health services with which the physician has a financial
relationship. The term "designated health services" includes, among others,
radiation therapy services and in-patient and outpatient hospital services. On
January 1, 1995, the Physician Ownership and Referral Act of 1993 became
effective in California. This legislation prohibits physician self-referrals for
covered goods and services, including radiation oncology, if the physician (or
the physician's immediate family) concurrently has a financial interest in the
entity receiving the referral. The Company believes that it is in compliance
with these rules and regulations.

A range of federal civil and criminal laws target false claims and
fraudulent billing activities. One of the most significant is the Federal False
Claims Act, which prohibits the submission of a false claim or the making of a
false record or statement in order to secure a reimbursement from a
government-sponsored program. In recent years, the federal government has
launched several initiatives aimed at uncovering practices which violate false
claims or fraudulent billing laws. Claims under these laws may be brought either
by the government or by private individuals on behalf of the government, through
a "whistleblower" or "qui tam" action. The Company believes that it is in
compliance with the Federal False Claims Act; however, because such actions are
filed under seal and may remain secret for years, there can be no assurance that
the Company or one of its affiliates is not named in a material qui tam action.

Legislation in various jurisdictions requires that health facilities obtain
a Certificate of Need ("CON") prior to making expenditures for medical
technology in excess of specified amounts. One of the Company's existing
customers was required to obtain a CON. Two more of the Company's more
recently-signed contracts are subject to CONs. The CON procedure can be
expensive and time consuming and may impact the length of time before Gamma
Knife services commence. CON requirements vary from state to state in their
application to the operations of both the Company and its customers. In some
jurisdictions the Company is required to comply with CON procedures to provide
its services and in other jurisdictions customers must comply with CON
procedures before using the Company's services.

The Company's Gamma Knife units contain Cobalt 60 radioactive sources. The
medical centers that house the Company's Gamma Knife units are responsible for
obtaining possession and user's licenses for the Cobalt 60 source.

The Company believes it is in substantial compliance with the various rules
and regulations that affect its businesses.

INSURANCE AND INDEMNIFICATION

The Company's contracts with equipment vendors generally do not contain
indemnification provisions. The Company maintains a comprehensive insurance
program covering the value of its property and equipment, subject to
deductibles, which the Company believes are reasonable.

The Company's customer contracts generally contain mutual indemnification
provisions. The Company maintains general and professional liability insurance.
The Company is not involved in the practice of medicine and therefore believes
its present insurance coverage and indemnification agreements are adequate for
its business.

EMPLOYEES

At December 31, 1999, the Company employed eight (8) employees on a
full-time basis. None of these employees is subject to a collective bargaining
agreement and there is no union representation within the Company. The Company
maintains various employee benefit plans and believes that its employee
relations are good.

The Company estimates that there were approximately 1,400 beneficial
holders of its Common Shares as of December 31, 1999.

The Company's Board of Directors authorized, and the Company completed in
March 1999 the repurchase of all of its remaining securities owned by two major
holders who acquired them in the Company's 1995 financial restructuring. The
repurchases were made directly from the holders.

The repurchased securities included shares of the Company's Common Stock,
and Warrants to acquire additional shares of Common Stock. The repurchased
securities represented approximately 12.6% of the

9
10

Company's then-issued and outstanding common shares and about 12.6% of its
then-fully diluted outstanding shares. The aggregate repurchase price paid by
the Company was approximately $702,000.

The Board of Directors also authorized in March 1999 the repurchase of up
to 500,000 additional shares of the Company's Common Stock in the open market
from time to time at prevailing prices. Approximately 196,000 shares were
repurchased in the open market pursuant to that authorization, through December
31, 1999, at a cost of approximately $498,000.

During 1999 holders of warrants and of options to acquire the Company's
common stock exercised their respective rights pursuant to such securities,
resulting in the Company issuing approximately 37,000 new shares of its common
stock, in exchange for payments totaling approximately $37,000.

On March 22, 1999, the Company adopted a Shareholder Rights Plan ("Plan").
Under the Plan, the Company made a dividend distribution of one Right for each
outstanding share of the Company's common stock as of the close of business on
April 1, 1999. The Rights become exercisable only if any person or group, with
certain exceptions, becomes an "acquiring person" (acquires 15 percent or more
of the Company's outstanding common stock) or announces a tender or exchange
offer to acquire 15 percent or more of the Company's outstanding common stock.
The Company's Board of Directors adopted the Plan to protect shareholders
against a coercive or inadequate takeover offer. The Board of Directors is not
aware that any person or group intends to make a takeover offer for the Company.

Following the transactions described above, as of December 31, 1999 the
Company had 5,732,964 fully diluted shares outstanding, including 3,813,042
issued and outstanding common shares, 1,370 common shares reserved for warrants,
1,912,867 common shares reserved for options, and 5,685 shares reserved pursuant
to the Company's Shareholder Rights Plan.

The Company did not pay cash dividends in 1999 and does not anticipate
paying cash dividends in 2000.

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

GENERAL

During the years ended December 31, 1999, 1998 and 1997, approximately
100%, 12% and 6% respectively, of the Company's revenues were derived from its
Gamma Knife business. The Company in November 1998 sold its diagnostic imaging
business which accounted for 0%, 88% and 94% of the Company's total revenues
during the years ended December 31, 1999, 1998 and 1997, respectively. As a
result, the Company was relieved of substantially all of the liabilities of the
imaging division, consisting of approximately $27,100,000 of debt and other
obligations, and received approximately $13,500,000 in cash. The sale of its
imaging division resulted in a one-time gain of $20,478,000 in 1998, which
eliminated the Company's capital deficiency. Following the sale, the Company's
operations were significantly reduced and it has substantially reduced its
staff. Accordingly the discussions below related to 1998 and 1997 predominantly
reflect the Company's operations prior to the sale of its imaging division.

The Company had net income of $2,707,000 ($0.68 per share) on medical
services revenues of $7,156,000 in 1999. Net income in 1999 included an
insurance expense credit of $325,000 and an income tax benefit of $716,000. The
Company had net income of $20,051,000 ($4.23 per share) on medical services
revenues of $35,162,000 in 1998. Included in net income for 1998 is a
$20,478,000 gain on disposal of product line less Sale-related income taxes of
$1,500,000.

TOTAL REVENUES



INCREASE INCREASE
1999 (DECREASE) 1998 (DECREASE) 1997
------ ---------- ------- ---------- -------
(IN THOUSANDS)

Medical services................................ $7,156 (79.6%) $35,162 (5.4%) $37,172


Medical services revenues decreased 79.6% in 1999 compared to 1998, and
decreased 5.4% in 1998 compared to 1997. Both decreases are primarily
attributable to the sale of the Company's imaging division, which occurred in
November 1998.

Gamma Knife revenues increased $2,995,000 and $1,772,000 in 1999 and 1998,
respectively, compared to the prior years. The 1999 increase was primarily due
to the commencement of four new Gamma Knife contracts during 1999 and full year
inclusion of the Company's fourth and fifth Gamma Knife units. The Company's
sixth Gamma Knife commenced operation in second quarter 1999, the seventh and
eighth commenced operation during third quarter 1999, and the ninth commenced
operation in late fourth quarter 1999. The Company's second Gamma Knife contract
expired during fourth quarter 1999 leaving a net of eight Gamma Knife units in
operation at December 31, 1999. The customer purchased the Gamma Knife after the
expiration of the contract for $1,200,000 in cash in November 1999. The 1998
increase vs. 1997 was primarily due to the commencement of the Company's fourth
Gamma Knife in March 1998 and the fifth Gamma Knife in July 1998, and full year
inclusion of the Company's third Gamma Knife unit.

MRI revenues decreased $26,498,000 and $1,821,000 in 1999 and 1998 compared
to prior years. The decreases were primarily attributable to the sale of the
imaging division. MRI revenues as a percentage of total medical services
revenues were 0%, 75%, and 76% in years 1999, 1998, and 1997, respectively.

The Company's non-MRI diagnostic imaging services revenues decreased
$3,345,000 and $1,763,000 in 1999 and 1998 compared to prior years. The decrease
in 1999 was due to the sale of the imaging division. The decline in 1998 was
primarily due to the continued decline of CT and Nuclear Medicine revenues and
the sale of the imaging division. Non-MRI diagnostic imaging services revenues
as a percentage of total medical services revenues were 0%, 10% and 14% for the
years ended 1999, 1998 and 1997, respectively.

Contract service revenues, consisting of Respiratory Therapy services and
Cardiac Catheterization Laboratory revenues, decreased $1,150,000 and $195,000
in 1999 and 1998 compared to prior years. These decreases were primarily
attributable to the sale of the imaging division.

COSTS OF OPERATIONS



INCREASE INCREASE
1999 (DECREASE) 1998 (DECREASE) 1997
------ ---------- ------- ---------- -------
(IN THOUSANDS)

Costs of operations..................... $2,165 (91.6)% $25,826 (4.5)% $27,044
Percentage of revenue................... 30.3% 73.5% 72.8%


The Company's costs of operations, consisting of payroll, maintenance and
supplies, depreciation and amortization, equipment rental and other operating
expenses (such as vehicle fuel, building rents, regional office costs,
insurance, property taxes, bad debt expense, fees and training expenses)
decreased $23,661,000 in 1999 as compared to 1998 and decreased $1,218,000 in
1998 compared to 1997.

Medical services payroll decreased by $7,084,000 in 1999 compared to 1998
and decreased by $446,000 in 1998 compared to 1997. This decrease is primarily
due to the sale of the imaging division and the fact that the Company does not
currently provide labor as a component of its Gamma Knife services. Medical
services payroll costs, as a percent of medical services revenues, were less
than 1% in 1999 and remained constant at 20% in years 1998 and 1997.

The Company's maintenance and supplies costs were 2%, 15% and 16% of
medical service revenues in 1999, 1998 and 1997, respectively. Maintenance and
supplies costs decreased $5,041,000 in 1999 compared to 1998 and decreased
$775,000 in 1998 vs. 1997. These decreases were primarily due to the sale of the
imaging division. Maintenance and supply costs for Gamma Knife services
increased $63,000 in 1999 compared to 1998 and decreased $30,000 in 1998
compared to 1997. The increase in 1999 was primarily due to the expiration of
the warranty period on three units. The decrease in 1998 compared to 1997 was
due to commencement of the warranty period on a replacement Gamma Knife unit at
an existing customer.

Depreciation and amortization decreased $3,940,000 in 1999 compared to 1998
and decreased $842,000 in 1998 compared to 1997. The decreases in 1999 and 1998
were both primarily attributable to the sale of the imaging division. The
decrease in 1999 was partially offset by the addition of four Gamma Knife units
during 1999. The decrease in 1998 was also due to fewer MRI units accounted for
as capitalized leases in 1998, offset by increases in equipment depreciation due
to the addition of two Gamma Knife units during 1998 and one unit in late 1997.
Depreciation and amortization for Gamma Knife services in 1999 and in 1998
increased $573,000 and $235,000, respectively, compared to prior years. The
increase in 1999 was mitigated because the Company's second Gamma Knife unit,
which was sold, was depreciated to its salvage value during third quarter 1999.

Equipment rental as a percentage of medical services revenues was 0% in
1999, 12% in 1998 and 7% in 1997. Equipment rental decreased $4,064,000 in 1999
compared to 1998 and increased $1,378,000 in 1998 compared to 1997. The decrease
in 1999 was due to the sale of the imaging division. The Company's Gamma Knife
services currently do not require the rental of equipment. The increase in 1998
is primarily due to two replacement and three new MRI units accounted for as
operating leases during 1998 and fourth quarter 1997, offset by decreases
associated with the sale of the imaging division.

Other costs of operations as a percentage of medical services revenues were
6%, 11% and 12% in 1999, 1998 and 1997, respectively. The decreases of
$3,532,000 in 1999 compared to 1998 and $533,000 in 1998 compared to 1997 were
primarily attributable to the sale of the imaging division. Other costs of
operations for Gamma Knife services increased $135,000 and $150,000,
respectively, compared to prior years. These increases were primarily due to
increased insurance costs and property taxes because of additional Gamma Knife
units, as well as increased marketing costs.

The Company's selling and administrative costs decreased $3,313,000 in 1999
compared to 1998 and $785,000 in 1998 compared to 1997. The decrease in 1999 was
primarily due to the sale of the imaging

division. Also during 1999, the Company revised its estimate regarding the need
for and the corresponding cost of liability insurance related to divested
operations. This change in estimate resulted in a $325,000 decrease to selling
and administrative expenses during fourth quarter 1999. Selling and
administrative costs increased as a percentage of revenue because of the lower
revenue base compared to the required level of selling and administrative costs.
The decrease in 1998 was primarily due to the sale of the imaging division and
decreased salary, investor relations and legal expenses.

Interest expense.......................... $1,309 (58.9)% $3,186 (13.2)% $3,671
Percentage of revenue..................... 18.3% 9.1% 9.9%


The Company's interest expense decreased $1,877,000 in 1999 compared to
1998 and decreased $485,000 in 1998 compared to 1997. The decrease in 1999 was
primarily attributable to the sale of the imaging division offset by increased
interest related to Gamma Knife units. The decrease in 1998 was primarily
attributable to the sale of the imaging division and decreased capitalized
lease-related interest, offset by increased interest related to additional Gamma
Knife units. Interest expense for Gamma Knife units increased $528,000 in 1999
and $470,000 in 1998 compared to prior years. Interest as a percentage of
revenue increased from 9.1% in 1998 to 18.3% in 1999 because all of the
Company's operating Gamma Knife units are financed by means of interest bearing
debt.

Percentage of revenue...................... (7.0)% (0.5)% 0.1%


The Company's gain on sale of product line decreased to $0 in 1999 and
increased $20,478,000 in 1998 compared to 1997. The gain on sale of product line
in 1998 represents the gain associated with the sale of the imaging division.
The gain was net of transaction costs of approximately $2,700,000. Transaction
costs include legal, investment banking and management bonuses related to the
sale of the imaging division; employee severance costs; and the costs related to
the discontinuance of the diagnostic imaging division. Gain on sale of assets
and early termination of capital leases increased $12,000 in 1999 compared to
1998 and decreased $823,000 in 1998 compared to 1997. The $821,000 gain on sale
of assets and early termination of capital leases in 1997 was primarily due to
the gain on early termination of a capital lease, an insurance settlement, and
gains on sales of assets.

Interest and other income increased $383,000 in 1999 and $102,000 in 1998
compared to prior years. The increase in both 1999 and 1998 was primarily due to
additional interest income from higher cash balances that are invested in
overnight securities.

Minority interest increased $335,000 in 1999 and $203,000 in 1998 compared
to prior years. Minority interest represents the pre-tax income earned by the
minority member's 19% interest in GKF. The increase in minority interest
reflects the increased profitability of GKF.

The Company received an income tax benefit of $716,000 in 1999 compared to
an income tax provision of $1,513,000 in 1998, a decrease in income tax expense
of $2,229,000. The $716,000 income tax benefit is primarily a result of an
overestimate of the federal and state income tax provision in 1998 resulting
from the sale of the imaging division. The overestimate was adjusted in 1999
when tax returns were completed for filing with taxing agencies. The Company's
income tax provision increased $1,503,000 in 1998 compared to 1997 primarily due
to the gain on sale of product line. The Company had a net operating loss
carryforward for federal income tax return purposes at December 31, 1999 of
approximately $8,330,000.

Net income per share..................... $ 0.68 (83.9)% $ 4.23 1,222% $ 0.32


The Company had net income of $2,707,000 in 1999 compared to net income of
$20,051,000 in 1998. Net income for 1999 included an insurance expense credit of
$325,000 and a tax benefit of $716,000. Net income for 1998 included a
$18,978,000 gain net of income taxes ($1,500,000) primarily from the Sale. Net
income for 1998, exclusive of the net gain from the sale of product line was
$1,073,000.

LIQUIDITY AND CAPITAL RESOURCES

The Company had cash and cash equivalents of $12,903,000 at December 31,
1999 compared to $11,114,000 at December 31, 1998. The Company's cash position
increased $1,789,000 due primarily to the availability of cash that had
previously been classified as restricted until April 15, 1999 to cover potential
claims relating to the sale of the imaging division. In addition, during the
second quarter 1999 the GK Financing, LLC Operating Agreement was amended to
require a minimum cash reserve of $50,000 which resulted in an increase in cash
and equivalents of $1,176,000.

Restricted cash of $50,000 at December 31, 1999 reflects cash that may only
be used for the operations of GK Financing, LLC. At December 31, 1998 restricted
cash of $2,226,000 reflected cash that may only be used for GK Financing, LLC
and amounts previously described as restricted under terms of the agreements
relating to the sale of the imaging division.

The Company's total cash, cash equivalents and restricted cash decreased
$387,000 in 1999 compared to 1998 due to the payment of federal and state income
taxes primarily related to the sale of the imaging division ($1,059,000 net of
refunds received), the Company's repurchase of Common Stock and Warrants
($1,164,000) and payment of costs relating to the sale of the imaging division
($1,159,000). Increased cash flow from operations and cash received on the sale
of a Gamma Knife unit ($1,200,000) mitigated this decrease.

Following the Company's stock repurchases the Company had Shareholders'
Equity of $12,639,000, Working Capital of $11,125,000, and Total Assets of
$36,986,000 at December 31, 1999 compared to Shareholders' Equity of
$11,096,000, Working Capital of $9,088,000, and Total Assets of $26,919,000 as
of December 31, 1998.

The Company invests its cash in overnight repurchase agreements and
commercial paper pending use in the Company's operations. The Company believes
its cash position combined with its working capital is adequate to service the
Company's cash requirements in 2000.

IMPACT OF INFLATION AND CHANGING PRICES

The Company does not believe that inflation has had a significant impact on
operations because a substantial majority of the costs that it incurs under its
customer contracts are fixed through the term of the contract.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

See the Index to Consolidated Financial Statements and Financial Statement
Schedules included at page A-1 of this report.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

On December 31, 1999 the local Grant Thornton offices that provided
accounting and tax services for the Company were sold to Moss Adams LLP, an
accounting and consulting firm. The Company has elected to retain Moss Adams as
its independent auditors and tax advisors. In light of its engagement of Moss
Adams, the Company will no longer engage Grant Thornton, LLP to audit the
Company's financial statements. Grant Thornton had served as the Company's
auditor during the year ended December 31, 1998. Ernst & Young had served as the
Company's auditor from 1983 through 1997.

The Company on December 14, 1998 engaged Grant Thornton, LLP as its
independent accountant to audit the Company's financial statements for the year
ended December 31, 1998. The Company and Grant Thornton, LLP had a long
established relationship as Grant Thornton had served as the Company's tax
advisor since 1990.

The Company, during its two prior fiscal years (1998 and 1997) and any
subsequent interim period preceding its change of independent accountant, did

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

The Board of Directors and Shareholders
American Shared Hospital Services

We have audited the accompanying consolidated balance sheet of American
Shared Hospital Services as of December 31, 1999, and the related consolidated
statements of income, shareholders' equity, and cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
American Shared Hospital Services at December 31, 1999, and the consolidated
results of their operations and consolidated cash flows for the year then ended
in conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1999, 1998 AND 1997

NOTE A -- BUSINESS AND BASIS OF PRESENTATION

1. Business

American Shared Hospital Services (the "Company") provides Gamma Knife
units to eight medical centers in California, Texas, Connecticut, Ohio,
Massachusetts, Arkansas, and Wisconsin. The Company provided shared diagnostic
imaging services to health care providers located in various geographic regions
of the United States through November of 1998. The five diagnostic imaging
services provided by the Company were Magnetic Resonance Imaging, Computed Axial
Tomography Scanning, Ultrasound, Nuclear Medicine, and Cardiac Catheterization
Laboratory services. On November 13, 1998, the diagnostic imaging services
product line was sold to a third party.

In June 1995, African American Church Health and Economic Services, Inc.
(ACHES) and ACHES Insurance Services, Inc. ("AIS") were incorporated. AIS is a
wholly owned subsidiary of ACHES. AIS is an insurance agency qualified to sell
life, health, and disability insurance in the states of California and New York.
ACHES, through AIS, sells life, health and disability insurance primarily to the
African-American Community. In 1999, the operations of ACHES and AIS were
discontinued.

On October 17, 1995, the Company (through American Shared Radiosurgery
Services ("ASRS")) and Elekta AB, the manufacturer of the Gamma Knife (through
its wholly owned United States subsidiary GKV Investments, Inc. ("GKV")),
entered into an operating agreement which formed GK Financing, LLC ("GKF"). GKF
provides alternative financing of Elekta Gamma Knife units and is the preferred
provider for Elekta AB of financing arrangements, such as fee-for-service lease
arrangements with health care institutions.

In November, 1999, OR21, Inc., was incorporated. This wholly-owned
subsidiary of the Company will provide the product "The Operating Room for the
21st Century(sm)", which is currently under development.

The consolidated financial statements include the accounts of the Company,
its wholly owned subsidiaries, CuraCare, Inc. ("CuraCare"), MMRI, Inc., European
Shared Medical Services Ltd., OR21, Inc., ACHES and its wholly-owned subsidiary,
AIS, and ASRS and its majority-owned subsidiary, GK Financing, LLC. The stock of
CuraCare was sold on November 13, 1998 in conjunction with the sale of the
diagnostic imaging services product line.

All significant intercompany accounts and transactions have been eliminated
in consolidation.

NOTE B -- ACCOUNTING POLICIES

1. Use of Estimates in the Preparation of Financial Statements

In preparing financial statements in conformity with generally accepted
accounting principles, management makes estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements, as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

2. Cash and Cash Equivalents

The Company considers all liquid investments with original maturities of
three months or less at the date of purchase to be cash equivalents. Restricted
cash is not considered a cash equivalent for purposes of the consolidated
statements of cash flows.

3. Restricted Cash

Restricted cash represents cash limited as to use by contractual
arrangement.

AMERICAN SHARED HOSPITAL SERVICES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1999, 1998 AND 1997

4. Accounts Receivable

Substantially all of the Company's revenue is provided by eight customers.
These customers constitute accounts receivable at December 31, 1999. The Company
performs credit evaluations of its customers and generally does not require
collateral. At December 31, 1999, the Company did not maintain an allowance for
doubtful accounts because management believes that accounts receivable are fully
collectible.

5. Accounting for Majority-Owned Subsidiary

The Company accounts for GK Financing, LLC (GKF), as a consolidated entity
due to its 81% majority-equity interest.

6. Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is determined using the straight-line method over the
estimated useful lives of the assets which for medical and office equipment is
generally 3 - 10 years.

7. Operating Leases

The Company leases Gamma Knife equipment to its customers under
arrangements accounted for as operating leases. Revenue is provided for and
recognized on a fee-for-service or contingent rental basis when the service is
delivered. The lease agreements are generally over ten to fifteen year terms. At
December 31, 1999, the Company held equipment under operating lease contracts
with customers with an original cost of $22,862,000 and accumulated depreciation
of $4,796,000.

8. Income Taxes

The liability method is used to account for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

9. Earnings Per Share

In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128 ("SFAS 128"), "Earnings per Share." SFAS
128 replaced the calculation of primary and fully diluted earnings per share
with basic and diluted earnings per share. Unlike primary earnings per share,
basic earnings per share excludes any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share. All earnings per share
amounts for all periods have been presented, and where appropriate, restated to
conform to the SFAS 128 requirements.

Basic earnings per share has been computed based on the weighted-average
number of common shares outstanding.

========== =========== ==========


10. Stock-Based Compensation

SFAS No. 123, "Accounting for Stock-Based Compensation," encourages but
does not require companies to record compensation cost for stock-based employee
compensation plans at fair value. The Company has chosen to continue to account
for stock-based employee compensation using the intrinsic value method
prescribed in Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations. Accordingly,
compensation cost for stock options granted to employees is measured as the
excess, if any, of the quoted market price of the Company's stock at the date of
the grant over the amount an employee must pay to acquire the stock. Disclosure
requirements in accordance with SFAS No. 123 are included in Note E.

11. Fair Value of Financial Instruments

The carrying amounts of financial instruments, including cash and cash
equivalents, restricted cash, accounts receivable, accounts payable, and other
accrued liabilities approximated their fair value as of December 31, 1999 and
1998, because of the relatively short maturity of these instruments. The
carrying amounts of the Company's various debt obligations approximated fair
value as of December 31, 1999 and 1998, based upon interest rates that are
currently available for the Company for issuance of instruments with similar
terms and remaining maturities.

12. Reclassifications

Certain amounts in the 1998 financial statements have been reclassified to
conform with the 1999 presentation.

NOTE C -- LONG-TERM DEBT

Long-term debt consists primarily of 8 notes with a financing company,
related to Gamma Knife construction and installation, totaling $19,290,000.
These notes accrue interest at fixed annual rates between 10.5% and 10.7%, are
payable in 84 monthly installments, mature between September, 2004, and
November, 2006, and are collateralized by the respective Gamma Knives.
Additionally, the Company has $3,142,000 in borrowings outstanding for deposits
for two Gamma Knives under construction at December 31, 1999 (note H). These
borrowings accrue interest at prime plus 2% (10.5 % at December 31, 1999), are
payable when the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1999, 1998 AND 1997

The provision (benefit) for income taxes differs from the amount computed
by applying the U.S. federal statutory tax rate (34% in 1999, 1998 and 1997) to
income (loss) before taxes as follows:



1999 1998 1997
----------- ----------- -----------

Computed expected tax..................... $ 677,000 $ 7,500,000 $ 536,000
Change in valuation allowance........... 62,000 (7,205,000) (1,600,000)
State income taxes, net of federal
benefit.............................. 116,000 1,400,000 10,000

----------- ----------- -----------
$ (716,000) $ 1,513,000 $ 10,000
=========== =========== ===========


At December 31, 1999, the Company had a net operating loss carryforward for
federal income tax return purposes of approximately $8,330,000 which expires
between 1999 and 2019. A substantial part of this carryforward is subject to
separate return limitations. The Company's ability to utilize its net operating
loss carryforwards and other deferred tax assets may be limited in the event of
a 50% or more ownership change within any three-year period.

The Company's estimated income tax liability for the year ended December
31, 1998 was overstated by approximately $700,000. This change in estimate is
the result of finalization of unresolved details associated with the 1998 sale
of the diagnostic imaging services product line. The effect of the resolution of
these details was estimated in the 1998 financial statements. The effect of the
final resolution was a reduction of the Company's income tax liability resulting
in an income tax benefit for the year ended December 31, 1999 as well as an
increase in the net operating loss carryforwards available to the Company. The
tax effected amount of the increase in net operating losses is approximately
$1,571,000 and is reflected as a change in carryovers and tax attributes in the
reconciliation from expected to actual income tax expense above.

NOTE E -- SHAREHOLDERS' EQUITY

1984 Stock Option Plan

Under the Company's 1984 Stock Option Plan (the "Plan"), as amended, a
total of 475,000 stock options were authorized for grant. The Plan terminated
according to its terms on March 1, 1994. Options granted pursuant to the Plan
generally had lives of 10 years from the date of grant, subject to earlier
expiration in certain cases, such as termination of the grantee's employment.

1995 Stock Option Plan

The Company's 1995 Stock Option Plan, providing for nonqualified stock
options and "incentive stock options," was approved by the Company's Board of
Directors on August 15, 1995, subject to shareholder approval, which was given
on October 6, 1995. Under the 1995 Plan, 330,000 common shares are reserved for
awards to officers and other key employees, non-employee directors, and
advisors. Provisions of the 1995 Stock Option Plan include an automatic grant to
each non-employee director of options to purchase up to 4,000 shares annually on
the date of the Company's Annual Shareholder Meeting, at an exercise price equal
to the market price of the Company's common shares on that date, until the
non-employee director has options for a total of 12,000 shares of the Company's
common stock in all Company plans. Directors who are appointed or elected to the
Company's Board of Directors on a date other than that of the Annual Shareholder
Meeting receive a pro-rata grant of such options, at an exercise price equal to
the market price of the Company's common shares on the date of grant.

On August 15, 1995, the Company's Chairman and Chief Executive Officer was
granted a ten-year, immediately exercisable option to purchase 1,495,000 common
shares for an exercise price of $.01 per share for which the Company recorded
compensation expense of $2,414,000. These options were granted to the officer as
final consideration for personal guarantees of credit facilities and for
continued employment with the Company.

The following table summarizes information about all options outstanding at
December 31, 1999:

At December 31, 1999 and 1998, 1,856,000 and 1,884,000 options,
respectively, were vested and exercisable.

At December 31, 1999, there were 1,370 warrants outstanding at an exercise
price of $.75 per warrant. These warrants are exercisable through May 2002.

Pro Forma Information related to Option Grants

Pro forma information regarding net income and earnings per share is
required by SFAS 123 for awards granted after December 31, 1995, as if the
Company had accounted for its stock-based awards to employees under the fair
value method of SFAS 123. The fair value of the Company's stock-based awards to
employees was estimated using a Black-Scholes option pricing model. The
Black-Scholes options valuation model was

F-13
36
AMERICAN SHARED HOSPITAL SERVICES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
DECEMBER 31, 1999, 1998 AND 1997

developed for use in estimating the fair value of traded options which have no
vesting restrictions and are fully transferable. In addition, the Black-Scholes
model requires the input of highly subjective assumptions including the expected
stock price volatility. Because the Company's stock-based awards to employees
have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its
stock-based awards to employees. The fair value of the Company's option grants
under the 1984 and 1995 Plans was estimated assuming no expected dividends and
the following weighted-average assumptions:



1999 1998 1997
---- ---- ----

Expected life (years)....................................... 9.5 9.5 9.5
Expected volatility......................................... 82.0% 93.8% 93.8%
Risk-free interest rate..................................... 5.9% 6.3% 6.3%


No options were granted during 1998. The weighted-average fair value of
options granted during 1999 was $2.54. For pro forma purposes, the estimated
fair value of the Company's options is amortized over the options' vesting
period. The Company's pro forma information follows:

NOTE F -- RETIREMENT PLAN

The Company has a defined contribution retirement plan for which
substantially all full-time employees are eligible. The plan does not currently
provide for a Company matching distribution.

NOTE G -- OPERATING LEASES

The Company leases office space and equipment under operating leases
expiring at various dates through 2002.

Future minimum payments under noncancelable operating leases having initial
terms of more than one year consisted of the following at December 31, 1999:



2000.............................................. $153,000
2001.............................................. 137,000
2002.............................................. 101,000

December 31, 1999, 1998 and 1997, respectively, and includes the above operating
leases as well as month-to-month rental and certain capital lease executory
costs.

NOTE H -- COMMITMENTS AND CONTINGENCIES

Under the terms of 2 Gamma Knife quotation agreements, the Company is
committed to purchase Gamma Knife equipment for $6,136,000 effective when the
equipment is placed in service at each customer location. At December 31, 1999,
the Company had $3,142,000 in deposits related to these purchase commitments
which are classified as construction in progress.

NOTE I -- REPORTABLE SEGMENTS

American Shared Hospital Services (ASHS) has one reportable segment: Gamma
Knife. The Gamma Knife segment treats certain vascular malformations and
intracranial tumors without surgery. Prior to November 1998 the Company also had
a Diagnostic Imaging Services segment which used medical diagnostic imaging
systems to facilitate treatment and the diagnosis of diseases and disorders.

The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. ASHS evaluates performance based
on profit or loss from operations before income taxes not including nonrecurring
gains and losses. Applicable general and administrative expenses are allocated
to segments based on relative percentage of revenues. Certain corporate expenses
are not allocated to the segments.

ASHS does not have significant intersegment sales transactions. The
segments share common expenses and provide management activities to one another
for which they charge management fees. These management fees are not considered
significant.

ASHS's reportable segments are strategic business units that offer
different products and services. They are managed separately because each
business requires different technology and marketing strategies.

NOTE J -- SALE OF PRODUCT LINE

On November 13, 1998, the Company consummated a sale of its diagnostic
imaging services product line to a third party. The diagnostic imaging services
line included Magnetic Resonance Imaging (MRI), Computed Axial Tomography
Scanning (CT), Ultrasound, Nuclear Medicine and Cardiac Catheterization
Laboratory services. The Company sold the assets of this product line for $13.5
million in cash and the assumption by the third party of approximately $27.1
million in liabilities of the Company. The Company recognized a gain on disposal
of product line of approximately $20 million in conjunction with this
transaction.

In conjunction with the product line sale, one of the Company's facilities
which provided certain administrative and scheduling functions was closed during
1999. At December 31, 1998, in accordance with the Emerging Issues Task Force
(EITF) Abstract 94-3, the Company accrued certain future exit costs related to
the sale of the product line and corresponding facility closure which totaled
$995,000 at December 31, 1998. The accrued costs include employee compensation
of $215,000, liability tail insurance coverage costs of $500,000, legal and
professional fees of $105,000, administrative costs of $115,000 and other costs
totaling $60,000. Insurance costs of approximately $400,000 were classified as
long-term as they were intended to be incurred subsequent to 1999. During 1999,
management revised its estimate regarding the use and corresponding cost of
liability tail insurance coverage. This change in estimate resulted in a
$325,000 decrease to selling and administrative expenses in the corresponding
Statement of Income for the year ended December 31, 1999.

The revenue and net operating income or losses from the disposed diagnostic
imaging services line for fiscal years ended 1998 and 1997 are presented at Note
I.
