ITEM 1.

BUSINESS

GENERAL


American Shared Hospital Services ("ASHS" and together with its subsidiaries,
the "Company") primarily provides shared diagnostic imaging services and
radiosurgery services to more than 200 hospitals, medical centers and medical
offices located in 22 states. The four principal diagnostic imaging services
provided by the Company are Magnetic Resonance Imaging (MRI), Computed Axial
Tomography Scanning (CT), Ultrasound, and Nuclear Medicine. Radiosurgery
services are performed by the Company through its subsidiary, GK Financing, LLC,
a California limited liability company ("GKF"), which provides Gamma Knife units
to three major medical centers. The Company also provides Cardiac
Catheterization Laboratory and Respiratory Therapy services.

ASHS was incorporated in the state of California in September 1983. ASHS's
predecessor, Ernest A. Bates, M.D., Ltd. (d/b/a American Shared Hospital
Services), a California limited partnership, was formed in June 1980. In October
1987, the Company acquired CuraCare, Inc. ("CuraCare") from Tenet Healthcare
Corporation (formerly known as National Medical Enterprises, Inc., "Tenet") for
$22,250,000. The acquisition of CuraCare significantly expanded and diversified
the services offered by the Company and increased its market penetration.

Prior to May 1989, the MRI services were provided through American Shared -
CuraCare ("AS-C"), which was a joint venture between the Company and MMRI, Inc.
("MMRI"), a California corporation and a wholly-owned subsidiary of Tenet.
Effective May 1, 1989, the Company purchased 100% of MMRI, ASHS's co-venturer in
AS-C, from Tenet for $4,200,000. MMRI's only asset is its 50% interest in AS-C.

Following its acquisition of CuraCare, the Company provided Respiratory Therapy
services to acute care hospitals. On December 31, 1994, the Company sold a
majority of its Respiratory Therapy department contracts and its Respiratory
Registry for approximately $4,000,000 in cash plus the assumption by the buyer
of $300,000 in liabilities.

In June 1995, the Company incorporated two new wholly-owned subsidiaries:
African American Church Health & Economic Services, Inc. ("ACHES"), a California
corporation, and ACHES Insurance Services, Inc., ("AIS"), a California
corporation and insurance agency qualified to sell life, health and disability
insurance in California and New York.

On October 17, 1995, the Company, through its wholly-owned subsidiary, American
Shared Radiosurgery Services ("ASRS"), and Elekta Holdings U.S., Inc.
("Elekta"), through its wholly-owned subsidiary, GKV Investments, Inc., a
Georgia corporation ("GKV"), entered into an agreement to form GKF to provide
alternative financing of Elekta Gamma Knife units in the United States and
Brazil. See "Gamma Knife Joint Venture."

RECENT DEVELOPMENTS

On March 12, 1998, the Company and MMRI entered into a Securities Purchase
Agreement (the "Purchase Agreement") with Alliance Imaging, Inc., and two of its
subsidiaries (collectively, the "Purchaser"). Pursuant to the Purchase
Agreement, the Purchaser would acquire all of the outstanding common stock of
CuraCare and all of the partnership interests in AS-C. These entities together
constitute the Company's diagnostic imaging business through which it provides
MRI, CT, Ultrasound, Nuclear Medicine services, as well as Cardiac
Catheterization Laboratory, and Respiratory Therapy services. The purchase price
is $13,552,000 in cash and the assumption by the Purchaser of the liabilities of
the Company's diagnostic imaging business, including approximately $26.1 million
in debt. Following the transaction, the Company will continue to provide Gamma
Knife radiosurgery services through its 81% interest in GKF.

The proposed transaction is subject to customary conditions, including receipt
of regulatory approvals and the approving vote of the holders of a majority of
the Company's outstanding common shares. The Company will seek the approval of
its shareholders in the near future, and expects the transaction to be
consummated in the third quarter of 1998. The Company, however, can give no
assurance that the transaction will in fact be consummated.

OPERATIONS

DIAGNOSTIC IMAGING SERVICES

General. Medical diagnostic imaging systems facilitate the diagnosis of diseases
and disorders at an early stage, often minimizing the amount and cost of care
needed to stabilize, treat or cure the patient and frequently obviating the need
for exploratory surgery. This diagnostic procedure can often be performed on an
out-patient basis eliminating the need for hospitalization. Diagnostic imaging
systems utilize energy waves to penetrate human tissue and generate
computer-processed cross-sectional images of the body, which can be displayed
either on film or on a video monitor. The Company provides its diagnostic
imaging services as of December 31, 1997, to 216 health care providers including
hospitals, clinics and physicians' offices located in 22 states. The Company's
technologists operate the equipment under the direction of licensed physicians
on the customer's staff who order procedures, interpret examination results and
maintain general responsibility for the patient.

Generally, the Company directly charges the hospitals, medical centers and
medical offices that have contracted for its services. The Company, to a
significantly lesser extent, bills patients directly or relies on third party
reimbursement. Third party reimbursement comprises approximately 10% of the
Company's medical services revenues.

The Company provides its diagnostic imaging services on both a shared and a
full-time basis. Shared services are provided based on agreed upon time periods.
The Company contracts with health care providers to provide equipment, operating
technologists, patient care coordinators and, in some cases, operating supplies.

The major advantages to a health care provider in contracting with the Company
for such services include: (i) avoiding the high cost of owning and operating
the equipment, (ii) avoiding the cost of hiring and training technical personnel
and support staff, (iii) reducing the risks associated with technological
obsolescence or under-utilization of the equipment and services, and (iv) not
being required to incur the cost of complying 


                                       3
<PAGE>   4
with certain governmental regulations.

MAGNETIC RESONANCE IMAGING

MRI utilizes magnetic fields and applied radio waves to obtain computer
processed cross-sectional images of the body. MRI provides clinical images
superior to alternative technologies in many applications by providing
information concerning neurologic, orthopedic, vascular and oncologic diseases.
MRI benefits from multiplanar imaging, obviates the need for ionizing radiation
and generally offers superior image resolution than previously available from
CT. The Company is a leading provider of high field strength MRI units on a
shared-service basis. The Company believes that it has a competitive advantage
because of its strategy of operating primarily top-of-the-line, high magnetic
field strength (1.5 Tesla superconductive magnet systems) mobile MRI units. MRI
units containing higher strength magnets are preferred technology because they
provide improved image quality, faster operating speed and greater potential for
new applications than do MRI units with less powerful magnets. Of the Company's
27 MRI units operating at December 31, 1997, 17 of such units are 1.5 Tesla
units, 7 are 1.0 Tesla units, and 3 are 0.5 Tesla units. All of the company's
MRI units are mobile or transportable. The Company had 146 MRI customers at
December 31, 1997, compared to 144 customers as of December 31, 1996. MRI
revenues constituted 76%, 75% and 73% of total medical services revenues in
years 1997, 1996 and 1995, respectively.

To a greater extent during the past several years, increased indications of MRI
utility plus reductions in equipment costs have allowed more hospitals to
purchase their own system instead of utilizing the Company's services. This has
contributed to a more competitive marketplace for the Company's services.

COMPUTED AXIAL TOMOGRAPHY

The Company operated 15 CT units as of December 31, 1997. CT utilizes multiple
x-ray beams and detectors to derive information that is then synthesized by
computers to produce cross-sectional images of organs or other areas of the
body. CT can be used to perform examinations of any part of the human anatomy
and provides a delineation of tissue not possible with conventional x-ray. CT
eliminates the problem of overlapping structures such as bone and soft tissue
inherent in images produced by conventional x-ray. The most commonly performed
CT examinations are of the brain, abdomen, and lumbosacral region, although
examinations of the chest, pelvis and extremities are also performed. With the
advent of MRI, the relative benefits of CT have decreased. Due to a variety of
factors, including increased competition among manufacturers of CT units, the
selling price of CT units has decreased thereby enabling more hospitals and
health care providers to acquire their own units instead of utilizing the
Company's services. Consequently, the Company has reduced its services in this
area in response to these changes in the market. CT revenues were approximately
8%, 10% and 10% of medical services revenues in 1997, 1996 and 1995,
respectively.

ULTRASOUND AND NUCLEAR MEDICINE

The Company owns and operates approximately 18 systems providing Ultrasound and
Nuclear Medicine services as of December 31, 1997. Ultrasound technology applies
high-frequency pulsed and continuous sound waves to the body. These sound waves
strike vessels and other internal body structures and echo back to the
equipment, where they register upon a video monitor. Ultrasound systems provide
a low medical risk, non-invasive procedure for determining the primary diagnosis
in renal, pancreatic, vascular and abdominal diseases and obstetrics. Nuclear
Medicine is a diagnostic imaging system utilizing short-lived radioactive
isotopes and computers to perform various examinations and process the resulting
medical data for the 


                                       4
<PAGE>   5
physician to establish the presence or absence of disease. Nuclear Medicine not
only provides an anatomic image, but also provides functional information that
cannot be provided by MRI or CT.

Nuclear Medicine services of the Company primarily consist of Single Photon
Emission Computed Tomography ("SPECT") wherein radioisotopes are injected into
the patient and the patient is subsequently imaged by a camera that moves around
the patient. The information received by the camera is then reconstructed by
computer to produce a three dimensional image. Although more costly, this
three-dimensional image yields a more accurate image when compared to other
Nuclear Medicine techniques. The Company provides SPECT services on a shared
service basis. Smaller health care providers which require fewer studies on a
regular basis may find it more cost-efficient to utilize SPECT on a
mobile-shared service basis than acquiring their own unit. The Company's Nuclear
Medicine services consist of one mobile SPECT system as of December 31, 1997.
Ultrasound and Nuclear Medicine revenues were approximately 6% of medical
services revenues in 1997 and 7% and 8% in 1996 and 1995, respectively.

GAMMA KNIFE

The Gamma Knife treats certain vascular malformations and intracranial tumors
without surgery. The Gamma Knife defines a small three dimensional intracranial
target volume and delivers a clinically significant dose of radiation
(Cobalt-60) within the target volume while avoiding the delivery of a clinically
significant dose beyond the target volume to healthy tissue.

The Company's first Gamma Knife, which is operated by GKF at a major university
medical center on a fee-per-procedure basis, commenced operation in September
1991. The Company's second Gamma Knife, which became operational on August 3,
1994, was contributed to GKF in February 1996. GKF commenced operation of its
third Gamma Knife unit in September, 1997 at a medical center on a
fee-per-procedure basis.


GAMMA KNIFE JOINT VENTURE

The Company, through ASRS, a California corporation, and Elekta, through its
wholly-owned subsidiary, GKV, entered into an operating agreement on October 17,
1995, to form GKF, a California limited liability corporation. Pursuant to the
operating agreement, as amended, the Company contributed its Gamma Knife units
and related assets to GKF in exchange for an 81% ownership interest held by ASRS
in GKF. GKV contributed cash for a 19% ownership interest in GKF and loaned
funds to GKF. GKF will be the preferred alternative financing provider in the
United States and Brazil for the purchase of Gamma Knife units sold by Elekta
Instruments, Inc., a U.S. subsidiary of the Gamma Knife manufacturer. GKF's
primary business will be to provide financing on a fee-for-service basis. The
results of operations of GKF are included in the consolidated financial
statements of the Company.

CUSTOMERS AND MARKETING

The market for services offered by the Company consists of major urban medical
centers, suburban and rural hospitals, health maintenance organizations ("HMOs")
and other managed care providers, governmental institutions, large
multi-specialty medical groups, physician offices and medical clinics. The type
of services offered by the Company in a given area may vary, depending upon such
factors as the size of the client medical care provider, the treatment needs of
specific patient groups within the client's service area, the modalities and
services required by the client and the number and nature of competitive
services available. 


                                       5
<PAGE>   6
The more capital intensive services, such as MRI, CT, and Gamma Knife, may be
effectively offered to urban medical centers, hospitals, large multi-specialty
medical groups, governmental institutions, larger HMOs and large third-party
purchasers of health services. The less capital-intensive services, such as
Ultrasound, Nuclear Medicine and, under certain circumstances, CT, are most
effectively offered to suburban and rural hospitals, physicians' offices and
medical clinics.

The Company believes that it offers among the broadest range of services to
health care providers of companies in the shared diagnostic imaging services
industry and therefore has a unique ability to service a broad spectrum of the
health care market. The Company continually monitors developments in the medical
equipment industry and makes an effort to acquire new modalities and equipment
as the opportunity arises in order to maintain its technologically advanced
services and to expand its market share. When the Company's medical equipment
does not generate adequate revenues, the Company seeks to sell such equipment
and to upgrade existing equipment or acquire newer, more advanced replacement
equipment when appropriate.

During the normal course of business, the Company has customer contracts that
terminate. The Company's sales representatives and operational managers must
replace terminating customers with new customers to maintain the Company's
revenues. Revenue fluctuations may occur dependent upon the maturation cycle of
terminating existing contracts and how quickly replacement customers can attain
the revenue levels of terminating customers. Revenues per customer are
historically higher for established customers. Revenue on all contracts and
contract amendments is recognized as earned based upon services provided for
each monthly period.

At the end of 1997, the Company employed twelve sales and marketing and two
regional operational managers. The Company markets its services through a direct
sales effort emphasizing the quality of its equipment, the reliability and
efficiency of its services, the ability to tailor its services to specific
customer needs and the cost containment benefits realized by the customer when
it utilizes the Company's services. No single customer accounted for 10% or more
of the Company's total revenues in 1997 or 1996.

COMPETITION

Utilization of the Company's diagnostic imaging services depends upon several
factors, including the number of physicians and their respective areas of
practice, the number and nature of competitive diagnostic units available, and
the size and demographics of the service areas. The market for diagnostic
imaging services is highly competitive. The Company faces competition from other
providers of mobile diagnostic services, some of which may have greater
financial resources than those of the Company, and from equipment manufacturers,
hospitals, imaging centers and health care providers owning in-house diagnostic
units. Significant competitive factors in the diagnostic services market include
equipment price and availability, performance quality, ability to upgrade
equipment performance and software, service and reliability. Mobile diagnostic
services providers with greater financial resources may have increased access to
capital and are better able to withstand adverse market conditions.

The increased competition among MRI equipment manufacturers has resulted in
greater availability to end users of new imaging equipment from manufacturers at
more competitive prices. Lower equipment pricing may make it more advantageous
for the end user to purchase the equipment rather than contracting with
full-service providers such as the Company.


                                       6
<PAGE>   7
GOVERNMENT REGULATION

Customers to whom the Company provides services receive payments for patient
care from federal government and private insurer reimbursement programs. As a
result of federal cost-containment legislation currently in effect, 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
placing material limitations on actual reimbursement for imaging services.
Because the reimbursement payment is predetermined, it does not necessarily
cover the cost of all medical services actually provided. Currently the DRG
system is not applicable to out-patient services. In 1986 and again in 1990 the
Congress enacted legislation requiring the Department of Health and Human
Services ("DHHS") to develop proposals for a PPS for hospital outpatient
services. DHHS has not as yet developed such a proposal, and the effect on the
Company's business of such a proposal, if made, cannot be predicted at this
time.

The Company's experience suggests that the hospital in-patient DRG system and
the expansion of managed care have had a favorable impact on the Company's
business. Rising costs in the health care field, together with the
implementation of the DRG system, have encouraged hospitals and other health
care providers to minimize costs. The Company's shared diagnostic imaging
services allow hospitals and other medical care providers to provide
sophisticated diagnostic equipment and qualified personnel at a cost directly
related to each service rendered to the patient. In recent years, however,
competitive factors (such as equipment availability and pricing) have limited
the Company's ability to benefit from the favorable impact of DRGs and managed
care.

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 reduce hospital revenues from the Medicare DRG
program by approximately 30%. This reclassification does not directly effect
other third party payors, which comprise the majority of the hospital's payors.
The Company is not currently directly impacted by the change, because all of its
existing contracts are reimbursed by the hospital to the Company on a
fee-per-service basis. However, the Company has entered into one contract that
has not yet commenced on a shared revenue basis. Revenues under this contract
will be reduced due to the reimbursement rate change. A significant number of
future contracts for Gamma Knife services may be based on a shared revenue
instead of a fee-for-service basis.

Several health care reform proposals have been promulgated during the Clinton
administration. These proposals attempt to increase access to care and to
control rising health care expenditures. Since a specific health care reform
policy has not been enacted, the impact on the Company's business of such a
proposal, if made, cannot be determined at this time.

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. 


                                       7
<PAGE>   8
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: clinical
laboratory services, physical therapy services, occupational therapy services,
radiology or other diagnostic services, radiation therapy services, durable
medical equipment, parenteral and enteral nutrients, equipment and supplies,
home health services, outpatient prescription drugs, inpatient 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 diagnostic nuclear
medicine and diagnostic imaging if the physician (or the physician's immediate
family) concurrently has a financial interest in the entity receiving the
referral. The Company cannot determine what impact this legislation will have on
the demand for its services.

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. The CON procedure can be expensive and time
consuming, and consequently a health care facility may elect to use the
Company's services rather than purchase imaging equipment subject to CON
requirements. 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 nuclear medicine imaging equipment requires the use of radioactive
isotopes for which there are existing governmental regulations covering storage,
use and disposal. All contracts for nuclear medicine imaging include
arrangements for the disposal of radioactive isotopes either by the supplier of
the isotopes or by agreement with the nuclear medicine department of the client
hospital. The Company is also subject to periodic review concerning the storage,
use and disposal of isotopes used in its nuclear medicine imaging equipment.

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

Mobile diagnostic imaging equipment must, where applicable, comply with federal
and state regulations concerning patient safety, equipment operating
specifications and radiation exposure levels. The equipment manufacturer is
primarily responsible for assuring compliance. The Company believes that its
equipment complies with all such regulations based on the quality control
features and specifications of the equipment manufacturers and the Company's
preventative maintenance program.

Certain states in which the Company operates require that certain of the
Company's personnel be licensed or certified. Such requirements generally
involve educational requirements and the payment of specified fees. All of the
Company's technical personnel are duly licensed or certified where required to
perform the services provided by the Company. The Company continually monitors
the compliance of its personnel with such licensing and certification
requirements.

The Company believes it is in substantial compliance with the various rules and
regulations which effect 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, equipment and vehicles, 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
and believes its present insurance coverage and indemnification agreements are
adequate for its business.

EMPLOYEES

At December 31, 1997, the Company employed approximately 189 employees on a
full-time basis and approximately 155 on a part-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 its employee relations are good.


ITEM 2.

PROPERTIES

The Company's corporate offices are located at Four Embarcadero Center, Suite
3620, San Francisco, California, where it leases 2,996 square feet for $8,893
per month. This lease runs through September 1999. The Company also leases
office space in Modesto, California. Additional properties are leased by the
Company principally for field operations and sales support in West Chicago,
Illinois, and Sacramento, California.

For the year ended December 31, 1997, the Company's aggregate net rental
expenses for all properties and equipment were approximately $3,285,000.

MARKET FOR REGISTRANT'S COMMON EQUITY
AND RELATED STOCKHOLDER MATTERS


The Company's common shares, no par value (the "Common Shares"), are currently
traded on the American Stock Exchange ("AMEX") and the Pacific Exchange ("PCX").
The Company's losses and net capital deficiency have caused the Company to no
longer satisfy the minimum criteria with respect to net income and net worth for
continued listing published by the AMEX. The per share trading price is also
below the minimum criteria of such exchange. The closing per share price of the
Common Shares was $1-11/16 at March 20, 1998. The Company has been advised that
its net capital deficiency is inconsistent with the criteria applied by the PCX
for continued listing on such exchange. The AMEX and the PCX are continuing to
monitor the Company's financial condition in order to determine whether the
Common Shares will continue to be listed for trading thereon.

The table below sets forth the high and low closing sales prices of the Common
Shares of the Company on the American Stock Exchange Consolidated Reporting
System for each full quarter for the last two fiscal years.

Medical services revenues increased 0.5% in 1997 compared to 1996, and increased
8.6% in 1996 compared to 1995. The 0.5% increase in 1997 and the 8.6% increase
in 1996 compared to prior years were primarily due to increases in MRI revenues.

MRI revenues increased 2% ($650,000) in 1997 compared to 1996 and increased 11%
($2,667,000) in 1996 compared to 1995. The increases in 1997 and 1996 were
primarily due to the commencement of new customer contracts and increased
utilization from contracts commenced in prior periods. MRI revenues as a
percentage of total medical services revenues were 76%, 75% and 73% in years
1997, 1996 and 1995, respectively.

The Company's non-MRI diagnostic imaging services revenues decreased 19%
($1,176,000) in 1997 compared to 1996 after a 1% ($60,000) decrease in 1996
compared to 1995. The revenue decline in 1997, compared to 1996, was primarily
attributable to decreased CT revenue which was due to utilization of two (2)
fewer CT units in 1997, and decreased nuclear medicine revenue due to the
termination of an in-house nuclear medicine contract in March 1997. Revenues
from CT operations decreased $614,000 in 1997 and $26,000 in 1996 from 1995
revenues of $3,563,000. The decrease in Nuclear Medicine and Ultrasound revenues
was $562,000 in 1997 and $34,000 in 1996 from a 1995 revenue base of $2,782,000.
Non-MRI diagnostic imaging services revenues as a percentage of total medical
services revenues was 14%, 17% and 18% for the years ended 1997, 1996 and 1995,
respectively. The Company's CT, Ultrasound, and Nuclear Medicine services
revenues continue to decline because customers are increasingly buying their own
equipment.

Contract service revenues consisting of Respiratory Therapy services and Cardiac
Catheterization Laboratory revenues increased $354,000 in 1997 compared to 1996
and decreased $415,000 in 1996 compared to 1995. The increase in 1997 was
primarily due to revenues from the Cardiac Catheterization Laboratory contracts
which commenced May 1996 and December 1996, respectively. The decrease in 1996
compared to 1995 resulted primarily from four terminated Respiratory Therapy
service contracts in 1995. The Company currently has one Respiratory Therapy
service contract.

Gamma Knife revenues increased $354,000 and $705,000 in 1997 and 1996,
respectively, compared to the prior years. The 1997 increase was primarily due
to the commencement of a third Gamma Knife unit in September 1997. The increase
in 1996 was a result of the inclusion of results of the Company's second Gamma
Knife beginning in February 1996.

The Company's cost 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 $1,027,000 in 1997 and $4,604,000 in 1996 compared to prior years.

Medical services payroll costs, the largest component of total cost of
operations, increased by $221,000 in 1997 compared to 1996 and increased by
$328,000 in 1996 compared to 1995. Medical services payroll costs as a percent
of medical services remains constant at 20% in years 1997, 1996 and 1995. The
1997 and 1996 increase was primarily due to staffing increases to service
additional MRI customer volumes and an increase in staffed units in 1997.

The Company's maintenance and supplies costs were 16%, 18% and 20% of medical
service revenues in 1997, 1996 and 1995 respectively. Maintenance and supplies
costs decreased $739,000 in 1997 compared to 1996 and decreased $68,000 in 1996
compared to 1995. The decreases in 1997 and 1996 are primarily attributable to
MRI maintenance cost savings.

Depreciation and amortization decreased $233,000 in 1997 compared to 1996 and
$1,671,000 in 1996 compared to 1995. The decrease in 1997 was primarily
attributable to decreased MRI and nuclear medicine depreciation as a result of
fewer MRI units accounted for as capital leases in 1997. The decrease in 1996 is
primarily attributable to the early adoption of Financial Accounting Standards
No. 121 (FAS 121) during the second quarter of 1995 as explained in detail
below. In addition, the majority of capital leases were extended as of October
1, 1995 thereby extending the depreciable life of the asset (as leased assets
are depreciated based on lease terms) and decreasing depreciation expense
commencing the fourth quarter of 1995.

Equipment rental as a percentage of medical services revenues was 7% in 1997, 9%
in 1996 and 8% in 1995. Equipment rental decreased $763,000 in 1997 compared to
1996 and increased $641,000 in 1996 compared to 1995. The decrease in 1997 is
primarily attributable to the return of five (5) MRI rental units which resulted
from mobile route consolidation and customer contract terminations. The increase
in 1996 is primarily attributable to the utilization of short-term MRI and CT
rentals to meet customer commitments.

Other costs of operations as a percentage of medical services revenues was 12%,
11% and 12% in 1997, 1996 and 1995, respectively. The increase of $487,000 in
1997 compared to 1996 reflects increased fuel, personal property tax costs,
insurance, and bad debt expenses. The decrease of $9,000 in 1996 compared to
1995 reflects a decrease in equipment and CON related costs and regional office
administrative costs offset by increased fuel costs, MRI space rental costs and
physician reading fees.

In connection with the early adoption of the statement of Financial Accounting
Standards No. 121 (FAS 121) during the second quarter of 1995, management
reviewed the recoverability of the carrying value of long-lived assets,
primarily fixed assets, goodwill and deferred costs. The Company initiated its
review of potential loss impairment due to the continuing changes in the health
care environment which have put downward pressure on customer and equipment
pricing and reduced forecasted operating results for certain assets to a level
below previous expectations. Following its review, management concluded that
there was an impairment in the recorded value of fixed assets, goodwill and
deferred costs under FAS 121 based on management's estimate of future
undiscounted cash flows over the estimated remaining useful life of certain
assets. Accordingly, an impairment loss of $4,425,000 was recorded in the second
quarter of 1995 based on the differences between the fair value of such assets
as determined by third parties and the recorded values. The impairment loss is
comprised of a charge for the write-downs of equipment and deferred assets of


                                       14

$3,825,000 (primarily MRI, CT and Nuclear Medicine) and goodwill of $600,000.

</TABLE>

The Company's selling and administrative costs increased $592,000 in 1997
compared to 1996 and decreased $3,123,000 in 1996 compared to 1995. The increase
in 1997 was primarily due to increased sales and administrative payroll costs,
building rental costs, audit and tax fees and legal fees associated with a
proposed acquisition of the Company which was not consummated. The decrease in
1996 is primarily attributable to a 1995 stock compensation expense totaling
$2,679,000 which is comprised of shares and options issued to the Company's
Chairman and Chief Executive Officer, Ernest A. Bates, M.D. Salary and wage
expense was charged $265,000 in the second quarter of 1995 for the issuance of
184,000 Common Shares to Dr. Bates for his continued services to the Company and
his personal guarantee of $6,500,000 of indebtedness of the Company. In
addition, during the fourth quarter of 1995, a charge to salary and wage expense
of $2,414,000 was recorded in connection with the grant to Dr. Bates, following
shareholder approval, of an option to acquire 1,495,000 additional Common Shares
for $0.01 per share as further consideration for his continued service to the
Company and his personal guarantee of $6,500,000 of the Company's new credit
facilities. See "Liquidity and Capital Resources." The decrease in 1996 was also
related to reduced legal and insurance costs.

</TABLE>

The Company's interest expense decreased $528,000 in 1997 compared to 1996 and
$1,111,000 in 1996 compared to 1995. The decrease in 1997 and 1996 are primarily
attributable to a lower outstanding amount of interest bearing debt due to the
repurchase by the Company on May 17, 1995 of $17,964,000 aggregate principal
amount of its Senior Subordinated Notes, the exchange for common shares
($413,000 aggregate principal amount) and payment at maturity ($360,000
aggregate principal amount) of its Senior Subordinated Notes in the third and
fourth quarters of 1996, respectively, and decreased capitalized lease-related
interest.

The Company's write-down of intangible assets decreased $600,000 in 1996 as
compared to 1995. The decrease in 1996 compared to 1995 is solely attributable
to the early adoption of FAS 121 in the second quarter of 1995. See "Cost of
Operations" above.

IMPACT OF YEAR 2000

Some of the Company's older computer programs were written using two digits
rather than four to define the applicable year. As a result, those computer
programs have time-sensitive software that recognize a date using "00" as the
year 1900 rather than the year 2000. This could cause a system failure or
miscalculations causing disruption of operations, including among other things,
a temporary inability to process transactions, send invoices, or engage in
similar normal business activities.

The Company has completed an assessment and will have to modify or replace
portions of its software so that its computer systems will function properly
with respect to dates in the year 2000 and thereafter. The total Year 2000
project cost has not been estimated, but is not expected to be material.

The Company believes that with modifications to existing software and
conversions to new software, the Year 2000 issue will not pose significant
operational problems for its computer systems. However, if such modifications
and conversions are not made or are not completed timely, the Year 2000 issue
could have a material impact on the operations of the Company.

The Company's gain on sale of assets and early termination of capital leases
increased $818,000 in 1997 compared to 1996 and decreased $223,000 in 1996
compared to 1995. The increase in 1997 was the result of a gain on the early
termination of a capital lease ($141,000) when the customer's in-house nuclear
medicine contract was terminated during March 1997, an insurance settlement
($388,000) following the loss of a mobile MRI unit in an accident during second
quarter 1997, a gain on sale of another MRI unit ($140,000) during third quarter
1997 and a gain on sale of a mobile SPECT unit ($115,000) in the fourth quarter
of 1997. Gain on sale of equipment fluctuates depending on the timing of asset
dispositions. The Company continues to sell non-essential assets in the normal
course of business.

</TABLE>

The Company had net income of $1,522,000 in 1997 compared to a net loss of
$353,000 for 1996. Net income for 1997 resulted in part from increased operating
margins and in part from gains from early termination of capital leases and sale
of assets.

The Company had a net loss of $353,000 for 1996 compared to net income of
$7,344,000 for 1995. The Company's net income for 1995 included an extraordinary
gain of $19,803,000 from its debt restructuring recorded on May 17, 1995. The
gain resulted from the purchase of $17,694,000 aggregate face amount plus
$8,853,000 of accrued and unpaid interest of the Company's 14-3/4% and 16-1/2%
Senior Subordinated Notes due October 15, 1996 net of cash, Common Shares and
warrants to purchase Common Shares issued and transaction related costs of
$3,893,000, $1,836,000 and $1,015,000, respectively. Included in the Company's
1995 results was a charge of $4,425,000 due to adoption of FAS 121 and stock
compensation expense of $2,679,000 (see "Selling and Administrative").

LIQUIDITY AND CAPITAL RESOURCES

The Company had cash and cash equivalents of $17,000 at December 31, 1997
compared to $368,000 at December 31, 1995. The Company's cash position decreased
$351,000 due primarily to the Company's debt payment requirements and working
capital needs.

Restricted cash at December 31, 1997 and December 31, 1996 reflects cash that
may only be used for the operations of GK Financing, LLC. The increase in
restricted cash is due to cash flow from Gamma Knife operations.

On May 17, 1995, the Company repurchased (the "Notes Repurchase") for cash and
securities approximately 96% of its outstanding Senior Subordinated Notes
("Subordinated Notes"). The Notes Repurchase, together with a December 1994
lease restructuring and the availability of up to $8,000,000 of new debt
financing, concluded a broad restructuring of the Company's obligations as more
fully explained in the Company's 1996 Form 10-K.

On December 29, 1995 and March 1, 1996, the Company further restructured certain
of its medical equipment leases and related notes (the "GE Notes") to extend the
terms of the leases for periods of up to an additional 26 months, to defer
certain monthly lease payments and to defer certain installment payments due at
the beginning of 1996. This further restructuring resulted in payment reductions
of approximately $1,200,000 for the Company in 1996 and subsequent years.

The various restructuring transactions described above cured all of the
Company's then-outstanding defaults relating to its debt and lease obligations.
The Company nevertheless remains highly leveraged and has significant cash
payment requirements under its equipment leases and credit facilities. Scheduled
equipment capital lease payments and operating lease payments during the 12
months ending December 31, 1998 are $7,487,000 and $2,551,000, respectively,
with related maintenance commitments of approximately 


                                       17
<PAGE>   18
$1,916,000. Scheduled interest and principal payments under the Company's other
debt obligations during such period are approximately $4,855,000 which excludes
the Company's revolving line of credit balance of $5,438,000 at December 31,
1997 ($5,207,000 at February 28, 1998) whose maturity has been extended to May
31, 1999. Although the Company's operating performance has improved, the Company
is uncertain it will have the cash resources to pay all of its obligations when
they are due. Accordingly, the Company will continue its program of expense
reductions, revenue enhancements and asset sales as well as refinancing or
renegotiating the terms of its fixed obligations ("Program"). The Company's
ability to meet its obligations when due are dependent upon the success of the
Company's Program. Any inability of the Company to meet its obligations when due
would result in a default which could permit the relevant obligor to accelerate
the obligations and seek other remedies including seizure of the Company's
medical imaging equipment. In such event, the Company would be forced to seek a
liquidation under Chapter 7 or a reorganization under Chapter 11 of the United
States Bankruptcy Code.

As part of the Program, the Company in March 1996 sold its Modesto buildings for
$650,000 in cash, and negotiated an increase in its working capital line of
credit to $5,500,000 and extended its maturity date by two years to May 31,
1999. The Company also completed in August 1996 an exchange offer (the "Exchange
Offer") for $413,000 aggregate principal amount of Subordinated Notes. The
purpose of the Exchange Offer was to improve the Company's capital structure and
relieve the Company of the requirement to pay $836,000 of principal and interest
in October, 1996 when the Subordinated Notes were to mature. In the Exchange
Offer, the Company issued approximately 287,000 additional shares of Common
Stock for $413,000 principal amount of Subordinated Notes. The remaining
$360,000 of the Subordinated Notes was paid at maturity on October 16, 1996.

In the long term, the Company believes that it must respond to fundamental
changes in the industry. The medical diagnostic imaging business, both mobile
and fixed, is in a period of consolidation as a result of the growth of managed
care and other competitive forces. Smaller companies, such as the Company, must
either grow through acquisitions or become part of larger enterprises in order
to compete successfully and achieve acceptable returns for their shareholders.
In light of the unavailability of capital to the Company and continuing weakness
in the price of its common stock, the Company has been willing to entertain
acquisition offers. In late 1996 and early 1997, the Company unsuccessfully
pursued a merger with a larger industry participant. In late 1997, the Company
was approached by Alliance Imaging, Inc., another major industry participant,
with respect to a sale of the Company's medical diagnostic imaging business. On
March 12 1998, the Company and Alliance entered into an agreement under which
the Company would sell its medical diagnostic imaging assets to Alliance for
consideration consisting of cash and the assumption of related liabilities. See
Part I, Item 1 "Business -- General --Recent Developments". The Company accepted
the proposed transaction in response to the industry trend toward consolidation,
the increasingly difficult competitive environment for smaller participants,
such as the Company, and to provide capital for the expansion of the Company's
radiosurgery services business. There can be no assurance that the transaction
will be consummated. If the transaction is not consummated, the Company will be
required to continue to operate as an independent entity, and to face the
serious liquidity and other problems referred to above.

IMPACT OF INFLATION AND CHANGING PRICES

The Company does not believe inflation has had a significant impact on
operations, because most of its customer contracts include a cost of living
price adjustment provision, which the Company believes will be sufficient to
offset the impact of any future inflation on the Company's costs of operation.

THE BOARD OF DIRECTORS

The following provides current information concerning those persons who serve on
the Company's Board of Directors.

automatic grant of Options from the Company's 1995 Stock Option Plan, to acquire

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Willie R. Barnes, the Secretary and a director of the Company, is a partner in
the law firm of Musick, Peeler & Garrett. That law firm performed legal services
for the Company in 1997 and may do so again in 1998. The management of the
Company is of the opinion that the fees paid to Mr. Barnes' law firm are
comparable to those fees that would have been paid for comparable legal services
from a law firm not affiliated with the Company.

Stanley S. Trotman, Jr., a director of the Company, is a managing director with
the Health Care Group of PaineWebber, Inc., an investment banking firm.
PaineWebber has provided investment banking services to the Company in the past
and will provide such services in 1998 with respect to the proposed sale of the
Company's diagnostic imaging business to Alliance Imaging, Inc. The management
of the Company is of the opinion that the fees agreed to be paid to Mr.
Trotman's firm are comparable to those fees that would have been paid for
comparable investment banking services from a firm not affiliated with the
Company.

                         Report of Independent Auditors

The Board of Directors and Stockholders
American Shared Hospital Services

We have audited the accompanying consolidated balance sheets of American Shared
Hospital Services as of December 31, 1997 and 1996, and the related consolidated
statements of operations, stockholders' equity (net capital deficiency), and
cash flows for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
American Shared Hospital Services at December 31, 1997 and 1996, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

The accompanying financial statements have been prepared assuming that American
Shared Hospital Services will continue as a going concern. As more fully
described in Note 1, the Company incurred operating losses in 1996 and 1995 and
has a significant working capital deficiency and a net capital deficiency at
December 31, 1997. In addition, the Company does not have sufficient cash
resources to meet debt obligations maturing in 1998. These conditions raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 1,
including a discussion of the proposed sale of certain significant assets
subsequent to December 31, 1997. The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

As discussed in Note 3 to the financial statements, in 1995, the Company adopted
Financial Accounting Standards Board Statement No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of".

1. BUSINESS AND BASIS OF PRESENTATION

BUSINESS

American Shared Hospital Services (the "Company") provides shared diagnostic
imaging services to health care providers located in approximately 22 states in
various geographic regions of the United States. The four diagnostic imaging
services provided by the Company are Magnetic Resonance Imaging, Computed Axial
Tomography Scanning, Ultrasound, and Nuclear Medicine. In addition, the Company
provides Gamma Knife units to three medical centers. The Company also provides
Cardiac Catheterization Laboratory and Respiratory Therapy services.

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.

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 in the United States and
Brazil. GKF is the preferred provider for Elekta AB of financing arrangements,
such as fee-for-service lease arrangements with health care institutions in the
United States and Brazil.

The consolidated financial statements include the accounts of the Company, its
wholly owned subsidiaries, CuraCare, Inc. ("CuraCare"), MMRI, Inc., European
Shared Medical Services Ltd., and its majority-owned subsidiary, GK Financing,
LLC.

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

             Notes to Consolidated Financial Statements (continued)



1. BUSINESS AND BASIS OF PRESENTATION (CONTINUED)

BUSINESS (CONTINUED)

The Company faces severe competition from other providers of diagnostic imaging
services, some of which have greater financial resources than the Company, and
from equipment manufacturers, hospitals, imaging centers and physician groups
owning in-house diagnostic units. Significant competitive factors in the
diagnostic services market include equipment price and availability, performance
quality, ability to upgrade equipment performance and software, service and
reliability. The Company's current financial problems may adversely affect its
ability to obtain and retain certain profitable customer contracts, and its
current high debt burden may affect its ability to offer technologically
advanced equipment in the future. Due to the Company's financial condition, the
two stock exchanges which list the Company's stock are continuing to monitor the
Company's financial condition to determine whether the Company's common shares
will remain listed. The Company is currently negotiating the sale of a
significant amount of its operating assets. (See Note 14 -- Subsequent Event.)

The Company leases substantially all of its medical equipment from one primary
provider.

BASIS OF PRESENTATION

The Company has reported net income of $1,522,000 in 1997, and net losses before
extraordinary items of $353,000, and $12,459,000 in 1996 and 1995, respectively.
At December 31, 1997, the Company has a working capital deficiency of $8,039,000
and a net capital deficiency of $8,953,000. In addition, the Company will not
have sufficient cash resources to repay its debt obligations at maturity and
will be required to seek new financing. There can be no assurance that such
financing will be available or that the terms of any such financing will be
acceptable to the Company.

These conditions raise substantial doubt about the Company's ability to continue
as a going concern. These financial statements do not include any adjustments to
reflect the possible future effects on the recoverability and classification of
assets or the amounts and classification of liabilities that may result from the
possible inability of the Company to continue as a going concern.

1. BUSINESS AND BASIS OF PRESENTATION (CONTINUED)

BASIS OF PRESENTATION (CONTINUED)

Management's plans with regard to these operating issues include the following:
continue to implement its program of expense reductions; identify and sell
non-essential assets; negotiate favorable concessions from major creditors and
enhance revenues by increasing customer contracts and equipment utilization. It
is uncertain as to whether these events will occur, and if they do, the extent
to which they will address the Company's operating issues. The Company is
currently negotiating the sale of a significant amount of its operating assets.
(See Note 14 - Subsequent Event.)


2. ACCOUNTING POLICIES

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

The preparation of the financial statements requires management to make
estimates and assumptions that affect reported amounts. These estimates are
based on information available as of the date of the financial statements.
Actual results could differ from those estimates.

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. The Company
maintains its cash in depository institutions which offer varying levels of
federal insurance. Restricted cash is not considered a cash and cash equivalent
for purposes of the consolidated statements of cash flows.

RESTRICTED CASH

Restricted cash represents cash limited as to use by a contractual arrangement.
Restricted cash at December 31, 1997 and 1996 reflects cash that may only be
used for the operations of GK Financing, LLC.

2. ACCOUNTING POLICIES (CONTINUED)

REVENUES AND ACCOUNTS RECEIVABLE

Revenue is recognized on a fee-for-service or contingent rental basis when the
service is delivered. Trade accounts receivable are principally from hospitals
and other health care providers located throughout the U.S., with no one
customer providing a significant percent of revenues. The Company performs
credit evaluations of its customers and generally does not require collateral.
The Company maintains an allowance for doubtful accounts at a level which
management believes is sufficient to cover potential credit losses. A
substantial portion of the Company's receivables collateralize its credit
facilities (see Note 6).

ACCOUNTING FOR MAJORITY-OWNED SUBSIDIARY

The Company accounts for GK Financing, LLC, as a consolidated entity due to its
81% majority-equity interest. The minority interest's 19% share of earnings
(loss) is netted against "Interest and Other Income" in the consolidated
statements of operations.

INVENTORIES

Inventories, which consist of minor medical equipment and supplies used in the
Company's business, are valued at the lower of cost or market, using a valuation
method which approximates FIFO (first-in, first-out).

PROPERTY AND EQUIPMENT

In 1995, the Company adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" (see Note 3). As a result of such adoption, property
and equipment are stated at cost, or the estimated fair value as determined by
third parties, if less.

Depreciation is determined using the straight-line method over the estimated
useful lives of the assets which for medical and transportation equipment is
generally 2 - 10 years.

Capitalized leased equipment consists primarily of mobile Magnetic Resonance
Imaging ("MRI") units, which include scanners and mobile vans. Capitalized
leased equipment is amortized over the term of the lease, which ranges from 24
to 96 months. Leasehold improvements are amortized over the shorter of the lease
term or the estimated useful life.

             Notes to Consolidated Financial Statements (continued)



2. ACCOUNTING POLICIES (CONTINUED)

INTANGIBLE ASSETS

Intangible assets represent the excess of cost of net assets acquired as the
result of the acquisition of businesses and are being amortized by the
straight-line method over 15 years. The Company annually assesses the
recoverability of these intangible assets by determining whether the
amortization of the intangible balance (for each business acquisition) over its
remaining life can be recovered through forecasted future operations using an
undiscounted cash flow methodology.

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.

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. The Company incurred a net loss for 1996 and 1995,
therefore, the incremental shares that arise as a result of the stock options
and warrants outstanding are anti-dilutive as they reduce the loss per share.

2. ACCOUNTING POLICIES (CONTINUED)

STOCK-BASED COMPENSATION

Statement of Financial Accounting Standards No. 123 ("SFAS 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.

COMPREHENSIVE INCOME

In June 1997, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
Income." SFAS 130 establishes standards for the reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements and is effective for fiscal years beginning after December
15, 1997. The Company believes that adoption of SFAS 130 will not have a
material impact on the Company's consolidated financial statements.

SEGMENT INFORMATION

In June 1997, the Financial Accounting Standards Board released Statement of
Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments
of an Enterprise and Related Information." SFAS 131 will change the way
companies report selected segment information in annual financial statements and
also requires those companies to report selected segment information in interim
financial reports to stockholders. SFAS 131 is effective for fiscal years
beginning after December 15, 1997. The Company believes that the application of
the new rules will not have a material impact on the Company's consolidated
financial statements.

2. ACCOUNTING POLICIES (CONTINUED)

FAIR VALUE OF FINANCIAL INSTRUMENTS

An estimate of the fair value of the Company's long-term debt would require the
use of a discounted cash flow analysis based on the Company's current
incremental borrowing rates for similar types of borrowing arrangements.
Management believes that the Company's creditors entered into the borrowing
arrangements as a result of the personal guarantees of an officer of the Company
and believes that the Company would be unable to obtain similar financing given
this fact and the current state of its financial matters. Accordingly,
management is unable, without incurring excessive costs, to estimate its
incremental borrowing rate, and considers estimation of fair value to be
impracticable.

The fair value of all other financial instruments approximate its recorded
values.

RECLASSIFICATIONS

Certain prior year balances have been reclassified to conform to the current
year presentation.


3. ADOPTION OF STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 121, "ACCOUNTING
FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED
OF"

In connection with the adoption of statement of Financial Accounting Standards
No. 121 ("SFAS 121"), during the second quarter of 1995, management reviewed the
recoverability of the carrying value of long-lived assets, primarily fixed
assets, goodwill and deferred costs based on the life of the assets. The Company
initiated its review of potential loss impairment due to the continuing changes
in the health care environment, which have put downward pressure on customer and
equipment pricing. These changes have resulted in recent operating results and
revised future forecasted operating results for certain assets being less than
previously planned. This situation led to the conclusion that there was a
potential impairment in the recorded value of fixed assets, goodwill and
deferred costs. Management's estimate of future undiscounted cash flows over the
useful life of certain assets was determined to be less than their recorded
values, indicating impairment of these assets under the provisions of SFAS 121.
An impairment loss of $4,425,000 was recorded as of the second quarter of 1995
based on the differences between the fair value, as determined by third parties,
and the recorded values of certain assets. The impairment loss is comprised of
write-downs of equipment of $3,825,000 (primarily MRI, CT, nuclear medicine, and
deferred assets), and a write-down of goodwill of $600,000.

No such impairment loss adjustment was required in 1997 or 1996.

5. SENIOR SUBORDINATED NOTES

During 1996 and 1995, the Company repurchased certain of its Senior Subordinated
Notes resulting in extraordinary gains of $0 and $19,803,000, respectively.

The extraordinary gain in 1995 was the result of a debt restructuring agreement
with four holders of $17,694,000 face value of its Senior Subordinated Notes. On
May 17, 1995, these Senior Subordinated Noteholders ("ex-Noteholders") received
approximately $3,900,000 in cash, plus 819,000 shares of common stock and
warrants for an additional 216,000 shares of common stock. As a result of the
additional options awarded to an officer of the Company, the ex-Noteholders were
granted 374,000 additional common shares and 98,000 additional warrants to
purchase common shares, to maintain their ownership interest at approximately
25% of the then fully diluted common shares. The warrants are immediately
exercisable at $0.75 per share. The remaining Senior Subordinated Noteholders
held $773,000 of the notes as of December 31, 1995. In addition, the debt
covenants were amended which thereby cured the events of default on the Senior
Subordinated Notes.

During 1996, the Company extended an exchange offer for the remaining $773,000
of Senior Subordinated Notes for common stock. On August 30, 1996, the Company
exchanged $413,000 of its Senior Subordinated Notes, and the interest accrued
thereon, for 287,000 shares of common stock valued at $430,000, using the market
price on the date of exchange. The remaining $360,000 of the Senior Subordinated
Notes, and the accrued interest thereon, was settled by the Company in cash on
October 15, 1996, the stated maturity date of the Senior Subordinated Notes.

6. LONG-TERM DEBT (CONTINUED)

Annual contracted maturities under the initial terms of long-term debt for the
five years after December 31, 1997 are as follows: $4,784,000 in 1998,
$8,136,000 in 1999, $1,325,000 in 2000, $1,181,000 in 2001, $519,000 in 2002 and
$775,000 thereafter.

The Company is severely limited by covenants in its credit agreements which
limit the Company's ability to merge with any other entity, to create
subsidiaries, to pay cash dividends, to repurchase stock for cash, incur
additional indebtedness, or to change the status of the equipment acting as
collateral in such a way as to impair its value.

In addition, the Company has pledged substantially all of its liquid assets and
substantially all of its personal property to secure its existing debt.

Notes Issued in Conjunction with Lease Restructuring

The Company converted $481,000 of unpaid use taxes into a note payable to its
primary provider of medical equipment. The note bears interest at 10.5% payable
in 60 monthly payments beginning February 1, 1995.

On December 23, 1996, the Company also converted past due service payments into
a $1,632,000 promissory note with its primary provider of medical equipment. The
note matures in January 2002 and bears interest at an annual rate of 10.75%. The
note is unsecured.

The Company also converted $147,000 of unpaid property taxes into a promissory
note payable to its primary provider of medical equipment. The note bears
interest at an annual rate of 10.75%, payable in 36 consecutive monthly
installments with the remaining balance due in January 2000.

6. LONG-TERM DEBT (CONTINUED)

Borrowings for Repurchase of Senior Subordinated Notes

The repurchase of Senior Subordinated Notes (the "Notes Repurchase") was
completed with the proceeds of three new credit facilities: a new revolving line
of credit (the "Revolver"), a term loan, and a Gamma Knife Loan. Under the
Revolver, the Company has available up to $5,500,000 according to a formula
based on eligible accounts receivable. The Revolver provides for interest
payments only (computed at the Bank of America prime rate plus 3.75%, 12.25% at
December 31, 1997) until maturity on May 31, 1999, when all amounts are due and
payable. The initial proceeds of $3,000,000 drawn under the Revolver were used
primarily to fund the cash consideration in the Notes Repurchase. At December
31, 1997, the Company had drawn $5,438,000 under the Revolver and, based on
eligible accounts receivable, had an additional $62,000 available under the
facility. Under the terms of the agreement, the Company's cash receipts are
processed through bank accounts controlled by the lender and the lender has a
first priority lien on all of the Company's accounts receivable, certain
equipment, inventory and general intangibles. The Revolver is personally
guaranteed by an officer of the Company.

The Company also entered into a $2,500,000 four-year loan agreement that will
amortize in 48 equal installments with interest at an annual rate of 15% (the
"Term Loan"). The Term Loan is secured by a first priority lien on certain
equipment, inventory and certain real property of the Company and a second
priority lien on the Company's accounts receivable and general intangibles. In
addition to funding the repurchase of the Subordinated Notes, the proceeds of
the Term Loan were applied to the refinancing of certain medical imaging
equipment and to provide working capital to the Company. The Term Loan is also
guaranteed by an officer of the Company.

The Company also entered into a $1,500,000 loan at an interest rate of 10.5%
(the "Gamma Knife Loan"). The proceeds of the Gamma Knife Loan were used to
refinance the Company's first Gamma Knife, to fund in part the Notes Repurchase,
and to provide working capital. The Gamma Knife Loan is collateralized with a
first priority security interest in one of the Gamma Knife units owned by the
Company. The payments on this loan were restructured from $90,431 per month to
$40,203 per month effective September 17, 1995, and to extend the loan term to
September 17, 1998, to match renegotiated terms of the underlying customer
contract.

At December 31, 1997, the Company has a net operating loss carryforward for
federal income tax return purposes of approximately $13,000,000 which expires
between 1999 and 2011. A substantial part of this carryforward is subject to
separate return limitations. The company has state carryforwards of varying
amounts. 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. Approximately $16,000,000 of net
operating loss carryforwards were used to offset the gain on early
extinguishment of the Senior Subordinated Notes in May 1995. (See Note 6 -
Long-Term Debt.)

8. STOCKHOLDERS' 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.

On August 15, 1995, the Stock Option Committee of the Board of Directors
approved the amendment of the terms of substantially all options outstanding
under the Company's 1984 Stock Option Plan, covering an aggregate of
approximately 165,000 shares, to reduce the initial exercise price to $1.625 per
share, which was the closing price of common shares on such date.

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 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 shares, at an exercise price equal to the
market price of the Company's common shares on the date of grant. Grants of
options for 19,000 shares were made pursuant to this provision during 1995.

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 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 1996 Plans was estimated
assuming no expected dividends and the following weighted-average assumptions:

<TABLE>

The weighted-average fair value of options granted during 1997 was $1.50. 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

1995-1996 Director Retainer Shares

On February 16, 1996, the Company's Board of Directors agreed that non-employee
directors could elect to receive some or all of their $5,000 annual Directors'
Retainer Fees for 1995 and/or 1996 in shares of the Company's common stock,
instead of in cash, at the rate of $1.6875 per share, which was the closing
price of the Company's common stock on that date. A total of 13,047 shares was
issued during 1996 for that purpose. The remaining Director Retainer Fees due to
non-employee directors for 1995 and/or 1996 were paid in cash during 1996.

Warrants Issued in Conjunction with Lease Restructuring

In 1995 and 1996, as consideration for the financial accommodations granted in
the restructuring of the Company's lease obligations, the Company issued
immediately exercisable warrants to its primary provider of leased equipment,
granting the right to purchase 97,853 and 127,147 common shares, respectively,
at a price of $.01 per share. In 1996, these warrants were exercised to purchase
225,000 common shares.

Options and Warrants Issued in Conjunction with Repurchase of Senior
Subordinated Notes

On May 17, 1995, simultaneous with the Notes repurchase (Note 5), the Company
issued 819,000 common shares (equal to approximately 20% of the Company's then
fully diluted common shares) and warrants to purchase 216,000 shares of common
stock (equal to approximately 5% of the then fully diluted common shares) to the
holders of $17,694,000 face value of the Company's Senior Subordinated Notes
that were repurchased. The warrants are immediately exercisable at $0.75 per
share, expiring on May 17, 2002.

As a result of the additional options awarded to an officer of the Company, the
ex-Noteholders were granted 374,000 additional common shares and 98,000
additional warrants to purchase common shares, to maintain their ownership
interest at approximately 25% of the then fully diluted common shares. The
warrants are immediately exercisable at $0.75 per share, expiring on May 17,
2002.

Capital shares reserved for future issuances total 2,951,000 shares at December
31, 1997.

9. RETIREMENT PLAN

The Company has a defined contribution retirement plan for which substantially
all full-time employees are eligible. Under the terms of the plan, the Company
may contribute a discretionary matching contribution on behalf of each
participant, determined each year by the Company, equal to a percentage of each
participant's contributions and applicable to the first 6% of each participant's
salary. The Company made no contributions to the plan in 1997, 1996 or 1995.


10. OBLIGATIONS UNDER CAPITAL LEASES

The Company leases MRI units and other equipment under capital leases having an
aggregate net book value of $12,284,000 at December 31, 1997. Amortization of
assets recorded under capital leases is included with depreciation expense, and
is primarily amortized over the life of the lease.

On December 30, 1994 (effective as of November 1, 1994 for most leases that were
considered capital prior to that date, and January 1, 1994 for leases that were
considered operating prior to that date) and at the end of 1995 and certain
leases again in early 1996, the Company and its major provider of medical
equipment entered into a restructuring of the obligations of the Company under
lease agreements.

Substantially all capital leases of the Company have been restructured and after
restructuring continued to meet the criteria to be accounted for as capitalized
leases. Under these modified leases, required payments by the Company are
scheduled to retire the unpaid principal balance over the extended lease terms
which will expire on various dates through December 31, 1999. All the operating
leases covered by the restructuring agreement in effect on October 31, 1994 were
modified to extend the payment schedules. As a result of modification of lease
terms, these leases met the criteria for capitalization, and were accounted for
as capital leases in the accompanying financial statements. Under all the
modified leases, the Company is entitled to purchase the equipment at its fair
market value, or to extend the relevant lease, at the end of the lease term.

The modified leases, as identified above, were further restructured effective
October 1, 1995. No payments were required for the months of October through
December 1995. During these months, interest was accrued and was added to the
outstanding principal balance of the capital leases. In addition, the leases
were extended up to an additional 26 months, where possible, to coincide with
the probable termination of the Company's end-user contracts. After this
restructuring, the modified leases continue to meet the criteria to be accounted
for as capitalized leases. Under all the modified leases, the Company will be
entitled to purchase the equipment at its fair value or to extend the relevant
lease at the end of the lease term.

10. OBLIGATIONS UNDER CAPITAL LEASES (CONTINUED)

On March 1, 1996, the Company received an offer from its primary provider of
medical equipment to restructure certain of its capital lease obligations. The
general terms of the restructuring provide for various months of no payments in
1996 followed by increased payments in the latter part of the agreements. The
Company completed this restructuring on March 8, 1996.

Future minimum lease payments, together with the present value of the net
minimum lease payments under capital leases at December 31, 1997, are summarized
as follows:

foregoing, it is understood that any violation of the restrictions set forth in
the preceding sentence by any director, officer or employee of the Parent, M Sub
or any Entity or any investment banker, financial advisor, attorney, accountant
or other representative acting on behalf of any such Person shall be deemed to
be a breach of this Section 6.4(a).

        (b) Neither the Board of Directors of the Parent nor any committee
thereof shall (i) withdraw or modify the approval or recommendation by such
Board of Directors or such committee of this Agreement, the Related Documents or
any of the transactions contemplated hereby or thereby, (ii) approve or
recommend any Alternative Transaction or (iii) cause or permit the Parent, M Sub
or any Entity to enter into any letter of intent, agreement in principle,
acquisition agreement or other agreement (an "Acquisition Agreement") with
respect to an Alternative Transaction unless the Board of Directors of the
Parent shall have previously terminated this Agreement pursuant to Section
9.1(f).

        (c) In addition to the obligations of the Parent set forth in paragraphs
(a) and (b) of this Section 6.4, the Parent shall immediately advise the
Purchasers orally and in writing of any request for information or of any
proposal or any inquiry regarding any Alternative Transaction, the material
terms and conditions of such request, proposal or inquiry and the identity of
the Person making such request, proposal or inquiry. The Parent will keep the
Purchasers fully informed of the status and details (including amendments or
proposed amendments) of any such request, proposal or inquiry.

        (d) Nothing contained in this Section 6.4 shall prohibit the Parent from
at any time taking and disclosing to its stockholders a position contemplated by
Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to the Parent's stockholders, in each case with respect to any Third
Party Proposal, if the Parent shall have provided the Purchasers with as much
advance notice of its position and proposed disclosure as is possible under the
circumstances; provided, however, that neither the Parent nor its Board of
Directors nor any Committee thereof shall, except as permitted by Section
6.4(b), withdraw or modify, or propose to withdraw or modify, its position with
respect to this Agreement, the Related Documents or any of the transactions
contemplated hereby or thereby or approve or recommend, or propose to approve or
recommend, an Alternative Transaction.

6.5      CONFIDENTIALITY.

         The Sellers and the Purchasers agree that, through and including the
Closing Date, they shall comply with that certain letter agreement relating to
matters of confidentiality dated as of July 24, 1997 (as amended, modified or
supplemented, the "Confidentiality Agreement").

6.6      NOTICE OF PROSPECTIVE BREACH.

         Each party shall immediately notify the other parties in writing upon
the occurrence, or failure to occur, of any event, which occurrence or failure
to occur would be reasonably likely to cause any representation or warranty of
such party that is contained



                                       30
<PAGE>   32

in this Agreement or any Related Document to be untrue or inaccurate in any
material respect at any time from the date of this Agreement to the Closing.

6.7      PUBLIC ANNOUNCEMENTS.

         Each party agrees that, except (i) as otherwise required by Law or
Order and (ii) for disclosure to its respective directors, officers, employees,
financial advisors, potential financing sources, legal counsel, independent
certified public accountants or other agents, advisors or representatives on a
need-to-know basis and with whom such party has a confidential relationship, it
will not issue any reports, statements or releases, in each case pertaining to
this Agreement or any Related Document to which it is a party or the
transactions contemplated hereby or thereby, without consulting in advance with
the other parties hereto.

6.8      COOPERATION REGARDING TAX FILINGS; SECTION 338(h)(10).

        (a) After the Closing, the Purchasers and the Sellers shall act in good
faith and cooperate with one another for the purpose of filing all Tax Returns
and reports required to be filed by any of them. Parent shall join Purchaser A
in a timely election pursuant to Section 338(h)(10) of the Code (and under any
comparable provision of any state or local law) with respect to the CT Shares
(the "338(h)(10) Election"). The parties hereto recognize that the 338(h)(10)
Election will result in the purchase of the CT Shares hereunder being treated as
a sale of assets by CT Sub for Federal income Tax purposes and for applicable
state and local tax purposes and that any Tax Liability arising with respect to
the 338(h)(10) Election (other than a Liability for Transfer Taxes described in
Section 10.14) shall be deemed a Covered Tax. None of the parties hereto shall
make any Tax Return or other filing that is inconsistent with the foregoing.

        (b) The Purchasers shall be responsible for the preparation and filing
of all 338(h)(10) Election forms and the Sellers shall execute and deliver to
Purchasers such documents as are reasonably requested to properly complete such
forms at least twenty (20) days prior to the date such 338(h)(10) Election is
required to be filed. The Sellers agree that the Purchasers shall be entitled to
determine the allocation of the Modified Aggregate Deemed Sales Price (as
defined in the treasury regulations promulgated under Section 338 of the Code)
among the assets of CT Sub in their sole discretion, and in accordance with
Section 338 of the Code and the regulations thereunder (including the allocation
of any adjustment to the Modified Aggregate Deemed Sales Price by reason of any
purchase price adjustment or indemnification payment under this Agreement), and
shall notify the Sellers of such determination as soon as possible after making
such determination. The Purchasers and the Sellers agree to act in accordance
with any such allocation in all relevant Tax Returns and filings.

        (c) Parent shall cause to be prepared and cause to be timely filed all
consolidated, combined or unitary federal, state, local or foreign Tax Returns
required to be filed with respect to Parent for all taxable periods ending
before or including the Closing Date and shall include CT Sub in all such
returns in which it is eligible to be



                                       31
<PAGE>   33

included. The Purchasers agree to cooperate with Parent and its Affiliates in
the preparation of the portions of such Tax Returns pertaining to CT Sub. The
Parent shall permit the Purchasers to review and comment on the portion of all
Tax Returns prepared by Parent pursuant to this Section 6.8(c) pertaining to CT
Sub, or the Partnership prior to the filing of such Tax Returns. Parent shall
cause to be timely paid all Taxes to which such Tax Returns relate for all
periods covered by such Tax Returns.

        (d) The extent to which Taxes of CT Sub and the Partnership for a
taxable period that includes but does not end on the Closing Date are treated as
Taxes for the period ending on or prior to the Closing Date shall be determined
for all purposes, including for purposes of calculating Covered Taxes, as
follows: (i) Taxes measured in whole or in part by net or gross income and Taxes
relating to specific transactions shall be apportioned on the basis of a closing
of the books of the Entity liable for such Tax at the close of business on the
Closing Date; provided, however, that all transactions not in the ordinary
course of business and not contemplated in this Agreement that occur on the
Closing Date after Purchaser A's purchase of the CT Shares shall be reported on
Purchaser A's federal income tax return to the extent permitted by Treas. Reg.
Section 1502-76(b((1)(3); and (ii) all other Taxes shall be prorated according
to the ratio of the number of days in such taxable period prior to and including
the Closing Date to the number of days in such taxable period.

        (e) The Sellers shall cause to be prepared all required federal, state,
local and foreign Tax Returns of CT Sub and the Partnership for any period which
ends on or before the Closing Date, for which Tax Returns have not been filed as
of the Closing Date (other than Tax Returns to be filed by Parent pursuant to
Section 6.8(c)). The Purchasers shall cause to be prepared and cause to be
timely filed all required federal, state, local and foreign Tax Returns of CT
Sub and the Partnership (other than Tax Returns to be filed by Parent pursuant
to Section 6.8(c)) for taxable periods beginning before and ending after the
Closing Date. The Sellers and Purchasers agree to cooperate with each other in
the preparation of such Tax Returns. The Purchasers shall permit Sellers to
review and comment on all Tax Returns prepared by the Purchasers pursuant to
this Section 6.8(e) and such Tax Returns shall be subject to the prior approval
of the Sellers which approval shall not be unreasonably withheld. The Sellers
shall permit the Purchasers to review and comment on all Tax Returns prepared by
the Sellers pursuant to this Section 6.8(e). Prior to the date such Tax Returns
are due, the Parent will provide the Purchasers with amounts equal to the
Covered Taxes, as shown on the Tax Returns to be filed under this Section
6.8(e), after taking into account any Tax or estimated Tax paid with respect to
such Covered Taxes prior to the Closing Date. Promptly after receipt by the
Purchasers of the amounts in respect of the Covered Taxes from the Parent, the
Purchasers will cause the applicable Tax Returns prepared by the Seller to be
filed.

        (f) Parent shall be entitled to any refund of Taxes paid by or with
respect to CT Sub that is attributable to taxable periods ending on or prior to
the Closing Date, and the Purchasers shall cause CT Sub to pay over to Parent
any such refunds (net of any Tax Liability attributable thereto and any expenses
incurred in the collection of such refund)



                                       32
<PAGE>   34

within fifteen (15) days after receipt thereof. If the amount of such refund
that is paid over by Parent is subsequently reduced by a Governmental Entity,
Parent shall pay to Purchasers an amount necessary to reflect such adjustment.

        (g) The Parent shall not file any claim for a refund or credit, or an
amended return claiming a refund or credit, after the Closing Date, for any Tax
paid by CT Sub without the prior written consent of the Purchasers, which
consent shall not be unreasonably withheld.

        (h) Each of the Purchasers and the Sellers shall promptly notify the
other party upon receipt of a notice of any pending or threatened Tax audit or
assessment (a "Tax Claim") that may affect the Tax Liabilities of CT Sub, or the
Partnership and for which any Seller would be liable under this Agreement;
provided, however, that no delay on the part of either party in so notifying the
other party shall relieve the other party from any liability or obligation
hereunder (unless, and then solely to the extent) that the other party is
materially and irrevocably prejudiced by such delay. Such notice shall be
accompanied by copies of all relevant documentation with respect to such Tax
Claim.

        (i) If the Sellers shall acknowledge in a writing delivered to the
Purchasers that such Tax Claim is properly subject to their indemnification
obligations hereunder and the Sellers shall have the financial resources to meet
such indemnification obligations, then subject to the further provisions of this
Section 6.8(i), the Sellers shall have the right to assume the defense of such
Tax Claim at their own expense and by their own counsel and other advisers,
which counsel and other advisors shall be reasonably satisfactory to the
Purchasers; provided, however, that the Sellers shall not have the right to
assume the defense of any Tax Claim, notwithstanding the giving of such written
acknowledgment, if the Sellers shall not have assumed the defense of such Tax
Claim in a timely fashion. Notwithstanding anything to the contrary contained
herein, if a Tax Claim involves, or could have a material effect on any material
matter beyond the scope of the indemnification obligations of the Sellers, the
Sellers and Purchasers shall jointly assume the defense of such Tax Claim at
their own expense. If the Sellers exercise their right to assume the defense of
a Tax Claim pursuant to and in accordance with this Section 6.8(i), (i) the
Purchasers shall be entitled to participate in such defense with their own
counsel and other advisors at their own expense, (ii) the Purchasers will
reasonably cooperate with the Sellers and their counsel and advisors in the
defense of such Tax Claim, and (iii) the Sellers shall not make any settlement
of such Tax Claim without the written consent of the Purchasers, which consent
shall not be unreasonably withheld, provided that consent may be withheld if any
Losses to be incurred by the Purchasers pursuant to such settlement are not
indemnified pursuant to the indemnification provisions set forth in Article VIII
hereunder.

        (j) If the Sellers shall assume the defense of a Tax Claim pursuant to
and in accordance with Section 6.8(i), the Sellers shall not be responsible for
any legal or other defense costs subsequently incurred by the Purchasers in
connection with the defense thereof. If the Sellers do not exercise their right
to assume the defense of a Tax Claim or



                                       33
<PAGE>   35

are otherwise restricted from doing so pursuant to Section 6.8(i), the Sellers
shall nevertheless be entitled to participate in such defense with their own
counsel and other advisors at their own expense. If the defense of a Tax Claim
is retained by the Purchasers, the Purchasers shall not be entitled to settle
such Tax Claim without the prior written consent of the Sellers, which consent
shall not be unreasonably withheld.

        (k) After the Closing Date, the Sellers and the Purchasers shall make
available to the other, as reasonably requested, all information, records or
documents relating to Tax Liabilities or potential Tax Liabilities of CT Sub or
the Partnership for all periods ending on or prior to the Closing Date, and
shall preserve all such information, records and documents until the expiration
of any applicable statute of limitations or extensions thereof.

        (l) All Tax Returns which are required to be prepared by Sellers
pursuant to Sections 6.8(c) and (e) shall be prepared and filed in a manner
consistent with past practice and applicable Law and, on such Tax Returns, no
position shall be taken, elections made or method adopted that is inconsistent
with positions taken, elections made or methods used in preparing and filing
similar Tax Returns in prior periods.

6.9      EXCHANGE PROCEEDS.

         If, between the date hereof and the Closing, any Entity or any Seller
receives any proceeds in consideration for the exchange of any of its assets
(solely, in the case of the Parent as it relates to the Purchased Parent
Assets), whether from the sale of any such assets, from insurance proceeds
payable on account of any loss or casualty to such assets, any proceeds from
the taking of such assets pursuant to the power of eminent domain, or any other
proceeds from whatever source relating to the disposition of such assets (the
"Exchange Proceeds"), the Sellers shall immediately notify the Purchasers of
the receipt of such Exchange Proceeds and shall consult with the Purchasers
with respect to the application of any such Exchange Proceeds.  The Sellers
shall ensure that any Exchange Proceeds received by any Entity shall either be
used to purchase replacement assets or shall be retained by the applicable
Entity.

6.10     NON-COMPETE; NON-SOLICITATION.

        (a) During the Non-Compete Period, the Parent shall not, and cause its
Affiliates not to, directly or indirectly, own, manage, control, participate in,
consult with, render services for, or in any manner engage in or represent any
business within any Restricted Territory that is competitive with the Business
or any product or services of the Business as such Business is conducted or
proposed to be conducted from and after the Closing Date; provided, however,
that nothing herein shall be deemed to prevent the Parent or any of its
Affiliates from engaging in any activities presently conducted or proposed to be
conducted by GK Finance or from providing any imaging modality as part of its
"Operating Room of the Twenty First Century" business.



                                       34
<PAGE>   36

        (b) During the Non-Compete Period, none of the Parent nor any Affiliate
shall directly or indirectly through another Person (i) induce or attempt to
induce any employee of any Purchaser or any Affiliate of such Purchaser to leave
the employ of such Purchaser or such Affiliate or in any way interfere with the
relationship between such Purchaser or any such Affiliate, on the one hand, and
any employee thereof, on the other hand, or (ii) induce or attempt to induce any
customer, supplier, licensee or other business relation of any Purchaser or any
Affiliate of such Purchaser to cease doing business with such Person or in any
way interfere with the relationship between any such customer, supplier,
licensee or business relation, on the one hand, and such Person, on the other
hand.

        (c) If, at the time of enforcement of this Section 6.10, a court holds
that the restrictions stated herein are unreasonable under the circumstances
then existing, the parties agree that the maximum period, scope or geographical
area reasonable under such circumstances shall be substituted for the stated
period, scope or area. The parties hereto acknowledge that money damages would
be an inadequate remedy for any breach of this Section 6.10. Therefore, in the
event of a breach or threatened breach of this Section 6.10, the Purchasers or
their successors or assigns may, in addition to other rights and remedies
existing in their favor, apply to any court of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce, or
prevent any violations of, the provisions of this Section 6.10.

6.11     CERTAIN TAX MATTERS.

         From the date hereof until the Closing Date, (i) the Parent shall and
shall cause each Entity to file all tax returns and reports ("Post-Signing
Returns") required to be filed in a manner consistent with past practices; (ii)
the Parent shall and shall cause each Entity to timely pay all Taxes shown as
due and payable on the Post-Signing Returns; (iii) the Parent shall and shall
cause each Entity to make provision for all Taxes payable for which no
Post-Signing Return is due prior to the Closing Date; (iv) the Parent shall
allow the Purchasers an opportunity to review and comment on any Post-Signing
Return prior to the due date of such Post-Signing Return; and (v) the Parent
will promptly notify the Purchasers of any action, suit, proceeding, claim or
audit pending against or with respect to the Parent or any Entity in respect of
any Tax where there is a possibility of a determination or decision which could
have an adverse effect on the Parent's or any Entity's Tax Liabilities or Tax
attributes.

6.12     ADVICE OF CHANGES; FILINGS.

         The Parent shall confer with the Purchasers on a regular and frequent
basis as reasonably requested by the Purchasers, report on operational matters
and promptly advise the Purchasers orally and, if requested by the Purchasers,
in writing of any change with respect to the Parent or any Entity.  The Parent
shall promptly provide to the Purchasers (or their counsel) copies of all
filings made by the Parent or any Entity with any



                                       35

Proxy Statement to be mailed to its stockholders as promptly as practicable
after responding to all such comments to the satisfaction of the SEC staff. The

Purchasers opportunity to review and comment upon any description of the
Purchasers or their Affiliates, this Agreement, the Related Documents or the

Parent with all necessary information reasonably requested with respect to
itself and Alliance solely for inclusion by the Parent in the Proxy Statement.
The Parent will notify the Purchasers promptly of the receipt of any comments
from the SEC or its staff and of any request by the SEC or its staff for
amendments or supplements to the Proxy Statement or for additional information

on the other hand, with respect to the Proxy Statement. If at any time prior to
the Stockholders Meeting there shall occur any event that should be set forth in
an amendment or supplement to the Proxy Statement, the Parent will promptly
prepare and mail to its stockholders such an amendment or supplement.

6.13     MAINTENANCE OF CASH AND CASH EQUIVALENTS.

<PAGE>   38

6.15     AUDITED FINANCIAL STATEMENTS.

         The Parent shall, and shall cause each of its Subsidiaries to, provide
the Purchasers and their advisors with such information (including, without
limitation, consolidating balance sheets and statements of operations as at

financial statements to incorporate the Entities in such form as presented in
Schedule 3.5(b) as well as individual columns for each of GK Finance, Parent
and each other Subsidiary of the Parent, in each case, as adjusted to give

6.18     CERTAIN EMPLOYEE MATTERS.

        (a)         On the Closing Date, the Purchasers shall or shall cause
the Entities or an Affiliate of the Purchasers, to continue the employment of
or offer employment, as applicable, to the employees of the Entities and Parent
to be identified by the Purchasers



                                       37
<PAGE>   39

prior to the Closing Date in accordance with the terms of a letter, dated of
even date herewith, delivered by Purchaser A to the Parent (any such employees
who so continue or accept such offer of employment being referred to herein as
the "Hired Employees"). Such employment shall be in a substantially similar
position as such Hired Employee held while employed by the applicable Entity or
Parent prior to the Closing, and the Purchasers shall have no Liability or
obligation to any other employees of the Parent or any of its Subsidiaries
(other than the Entities as set forth herein). Prior to the Closing, Parent and
the Entities shall take such actions and, after the Closing Date, Parent and the
Purchasers shall take, and the Purchasers shall cause the Entities to take, such
actions as are necessary so that each Hired Employee shall cease to be entitled
to participate in or accrue benefits under any of Parent's Employee Benefit
Plans, programs, policies and arrangements except to the extent required by
applicable Law. The Purchasers shall, or shall cause the Entities or an
Affiliate of the Purchasers, to take such actions as may be necessary such that,
subject to the provisions of this Section 6.18, on and after the Closing Date,
each Hired Employee shall be eligible to participate in, and be subject to the
provisions of, the Employee Benefit Plans (including a 401(k) plan and a
flexible benefits plan), programs, personnel policies and guidelines sponsored
or maintained by Alliance, and applicable for employees of Alliance or its
Affiliates in a similar position, subject to the satisfaction of all the
eligibility criteria for participation thereunder (except as otherwise provided
in this Section 6.18).

        (b) With respect to the Alliance Employee Benefit Plans, programs,
personnel policies and guidelines, Alliance shall grant all Hired Employees from
and after the Closing Date credit for all service with the Entities and Parent
prior to the Closing Date for all purposes. Alliance shall take such actions as
are necessary to provide that on the Closing Date all Hired Employees and their
spouses and dependents shall be immediately covered by the group health plan
maintained by Alliance which shall (i) provide immediate coverage as of the
Closing Date without any waiting period, (ii) waive any pre-existing condition
exclusions or limitations, and (iii) provide that any amounts paid by Hired
Employees through the Closing Date for medical expenses that are treated as
deductible, co-insurance and out-of-pocket payments under the Parent's health
plan shall reduce the amount of any deductible, co-insurance or out-of-pocket
payments required to be paid for a similar period under the Alliance health
plan; provided, however, that the Sellers shall provide Alliance with a list of
all current and former employees participating in the Parent's health plan along
with a listing of each employee's deductible and co-insurance payments through
the Closing Date.

        (c) Effective as of the Closing, the Purchasers shall assume the
Parent's or Entities' obligations with respect to accrued sick pay, personal
holidays and vacation pay for Hired Employees, provided that the vacation pay
costs as of the Latest Balance Sheet Date have been accrued and reflected on the
Latest Balance Sheet.

        (d) Parent shall take such actions as are necessary to provide that the
Hired Employees are fully vested in their benefits under the Retirement Plan for
Employees of Parent and CT Sub (the "ASHS 401(k) Plan"). Parent shall also take
such actions as are



                                       38
<PAGE>   40

necessary to provide that the Hired Employees will be eligible to receive
distributions from the ASHS 401(k) Plan that will be eligible for rollover to
the Alliance "401(k)" plan. The Purchasers shall take such action as is
necessary after the Closing Date to provide that the Alliance "401(k)" plan will
allow rollovers of distributions from the ASHS 401(k) Plan.

        (e) After the Closing Date, the Purchasers and the Sellers agree to take
such actions as are necessary to provide for the transfer of the account
balances of the flexible spending accounts of each Hired Employee from Parent's
"Section 125" plan to the Alliance "Section 125" plan and the Purchasers shall
provide for the reimbursement from the Alliance "Section 125" plan of medical
and childcare expenses incurred by Hired Employees during 1998.

        (f) After the Closing Date, the Purchasers shall be responsible for
providing health care continuation coverage pursuant to the requirements of the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), to
the extent required by COBRA, for all former employees of the Entities and/or
their "qualified beneficiaries" (as such term is defined in Part 6 of Title I of
ERISA) who were receiving health care continuation coverage under COBRA prior to
the Closing Date or who are or become eligible to receive such coverage on or
after the Closing Date. As of the date hereof, there were 2 former employees of
the Entities and/or their "qualified beneficiaries" who were receiving health
care continuation coverage under COBRA and 8 former employees who experienced a
"qualifying event" under COBRA.

<PAGE>   45

                (i) the untruth, inaccuracy or breach of any representation or
        warranty (without regard to whether such representation or warranty is
        qualified by reference to materiality or "Material Adverse Effect") of
        the Sellers contained herein, in any Related Document, or in any
        certificate delivered by any Seller relating thereto delivered in
        connection herewith (or any facts or circumstances constituting any such
        untruth, inaccuracy or breach);

                (ii) the breach of any agreement or covenant of the Sellers
        contained in this Agreement or in any Related Document;

                (iii) any Liability of any Entity in any manner related to a

        accounting with respect to a Tax period ending on or prior to the
        Closing Date.

        (b) Subject to the further terms of this Article VIII, each of Alliance

<PAGE>   46
                    (iv) any Liability for Transfer Taxes to be borne by
        Purchasers or Alliance pursuant to Section 10.14.

        (c) Notwithstanding the foregoing the Purchasers shall not be entitled
to indemnification hereunder for any Losses arising as a result of the untruth
or inaccuracy of any representation or warranty to the extent that a Liability
arising as a result of such untruth or inaccuracy is reflected as a Liability in
the financial statements delivered on the date hereof pursuant to Section 3.5
hereof.

        (d) Absent fraud, the rights of the parties for indemnification relating
to this Agreement and the transactions contemplated hereby and under the Related
Documents shall be strictly limited to those contained in this Article VIII, and
such indemnification rights shall be the exclusive remedies of the parties
subsequent to the Closing Date with respect to any matter relating to this
Agreement or arising in connection herewith.

8.2      ASSERTION OF CLAIMS.

         No claim shall be brought for a breach of a representation or warranty
under Section 8.1 hereof unless the Indemnified Persons, or any of them, at any
time prior to the applicable Survival Date, give the Indemnifying Persons (a)
written notice of the existence of any such claim, specifying the nature and
basis of such claim and the amount thereof, to the extent known or (b) written
notice pursuant to Section 8.3 of any Third Party Claim, the existence of which
might give rise to such a claim.  Upon the giving of such written notice as
aforesaid, the Indemnified Persons, or any of them, shall have the right to
commence legal proceedings prior to or subsequent to the Survival Date for the
enforcement of their rights under Section 8.1.

8.3      NOTICE AND DEFENSE OF THIRD PARTY CLAIMS.

         The obligations and liabilities of an Indemnifying Person with respect
to Losses resulting from the assertion of claim or Liability by third parties
other than in respect of Tax Claims (each, a "Third Party Claim") shall be
subject to the following terms and conditions:

        (a) The Indemnified Persons shall promptly give written notice to the
Indemnifying Persons of any Third Party Claim which might give rise to any Loss
by the Indemnified Persons, stating the nature and basis of such Third Party
Claim, and the amount thereof to the extent known; provided, however, that no
delay on the part of the Indemnified Persons in notifying any Indemnifying
Persons shall relieve the Indemnifying Persons from any liability or obligation
hereunder unless (and then solely to the extent) the Indemnifying Person thereby
is materially and irrevocably prejudiced by the delay. Such notice shall be
accompanied by copies of all relevant documentation with respect to such Third
Party Claim, including any summons, complaint or other pleading which may have
been served, any written demand or any other document or instrument.



                                       45
<PAGE>   47

        (b) If the Indemnifying Persons shall acknowledge in a writing delivered
to the Indemnified Persons that such Third Party Claim is properly subject to
their indemnification obligations hereunder, then the Indemnifying Persons shall
have the right to assume the defense of any Third Party Claim at their own
expense and by their own counsel, which counsel shall be reasonably satisfactory
to the Indemnified Persons; provided, however, that the Indemnifying Persons
shall not have the right to assume the defense of any Third Party Claim,
notwithstanding the giving of such written acknowledgment, if (i) the
Indemnified Persons shall have been advised by counsel that there are one or
more legal or equitable defenses available to them which are different from or
in addition to those available to the Indemnifying Persons, and, in the opinion
of the Indemnified Persons, counsel for the Indemnifying Persons could not
adequately represent the interests of the Indemnified Persons because such
interests could be in conflict with those of the Indemnifying Persons, or (ii)
the Indemnifying Persons shall not have assumed the defense of the Third Party
Claim in a timely fashion.

        (c) If the Indemnifying Persons shall assume the defense of a Third
Party Claim (under circumstances in which the proviso to the first sentence of
Section 8.3(b) is not applicable), the Indemnifying Persons shall not be
responsible for any legal or other defense costs subsequently incurred by the
Indemnified Persons in connection with the defense thereof. If the Indemnifying
Persons do not exercise their right to assume the defense of a Third Party Claim
by giving the written acknowledgment referred to in Section 8.3(b), or are
otherwise restricted from so assuming by the proviso to the first sentence of
Section 8.3(b), the Indemnifying Persons shall nevertheless be entitled to
participate in such defense with their own counsel and at their own expense. If
the defense of a Third Party Claim is assumed by the Indemnified Persons, the
Indemnified Persons shall not be entitled to settle such Third Party Claim
without the prior written consent of the Indemnifying Persons, which shall not
be unreasonably withheld.

        (d) If the Indemnifying Persons exercise their right to assume the
defense of a Third Party Claim, (i) the Indemnified Persons shall be entitled to
participate in such defense with their own counsel at their own expense and (ii)
the Indemnifying Persons shall not make any settlement of any claims without the
written consent of the Indemnified Persons, which shall not be unreasonably
withheld.

8.4      SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

        (a) Subject to the further provisions of this Section 8.4, the
representations and warranties contained in this Agreement, the Related
Documents, or in any certificate or other writing delivered in connection with
this Agreement shall survive the Closing Date until April 15, 1999; provided,
however, that (i) the representations and warranties contained in Sections 3.1,
3.2, 3.3, 3.4, 3.21, 4.1, 4.2, 4.3, 4.4, 5.1, 5.2 and 5.3 (other than the
covenant set forth therein which shall survive in accordance with the second
sentence of this Section 8.4(a)) of this Agreement shall survive indefinitely
and (ii) the representations and warranties contained in Sections 3.8 and 3.20
of this Agreement shall survive the Closing Date until the expiration of any
applicable statue of limitations (those



                                       46
<PAGE>   48

representations and warranties referenced in the foregoing clauses (i) and (ii),
being the "Excluded Representations and Warranties") for Third Party Claims
applicable to the matters covered thereby. The covenants and other agreements of
the parties contained in this Agreement and the Related Documents (including the
indemnity provided for in Section 8.1(a)(iii) of this Agreement) shall survive
the Closing Date until they are otherwise terminated by their terms. The
obligations of the Sellers under Section 8.1(a)(iv) and (a)(v) shall survive the
Closing Date until the expiration of any applicable statute of limitations with
respect to the matters set forth therein. The obligations of Alliance and the
Purchasers under Section 8.1(b)(iv) shall survive the Closing Date until the
expiration of any applicable statute of limitations with respect to the matters
set forth therein.

        (b) For convenience of reference, the date upon which any representation
or warranty contained herein shall terminate, if any, is referred to herein as
the "Survival Date".

        (a) Indemnity Baskets for the Sellers. The Purchaser Indemnified Persons
shall not have the right to be indemnified for breaches of representations and
warranties pursuant to Section 8.1(a)(i) unless and until the Purchaser
Indemnified Persons shall have incurred on a cumulative basis aggregate Losses
(without giving effect, in determining whether and to what extent
representations and warranties were breached or Losses were incurred, to
qualifications therein relating to materiality or "Material Adverse Effect") in
an amount of $500,000, in which event the right to be indemnified shall apply in
respect of all Losses; provided, however, that in no event shall the limitations
set forth in this Section 8.5(a) apply with respect to the Excluded
Representations and Warranties.

        (b) Indemnity Limitations for the Sellers. The sum of all Losses

8.1(a)(i) shall not exceed $2,000,000; provided, however, that in no event shall
the limitations set forth in this Section 8.5(b) apply with respect to the
Excluded Representations and Warranties.

        (a) Indemnity Baskets for the Purchasers and Alliance. The Seller
Indemnified Persons shall not have the right to be indemnified for breaches of

extent representations and warranties were breached or Losses were incurred, to

an amount of $500,000, in which event the right to be indemnified shall apply in
respect of all Losses; provided, however, that in no event shall



                                       47
<PAGE>   49

the limitations set forth in this Section 8.6(a) apply with respect to the

        (b) Indemnity Limitations for the Purchasers and Alliance. The sum of

pursuant to which indemnification is payable by the Purchasers and Alliance
pursuant to Section 8.1(b)(i) shall not exceed $2,000,000; provided, however,

         The parties hereto agree that any indemnification payment shall be
treated as an adjustment to the Purchase Price.

         This Agreement may be terminated at any time prior to the Closing by:

        (a) the mutual written consent of the parties hereto; or

        (b) the Purchasers or Alliance, if there has been a breach by any Seller
of any of the representations or warranties in this Agreement or in any Related
Document, individually or in the aggregate, in any material respect (except for
representations and warranties which are qualified by their terms by a reference
to materiality or "Material Adverse Effect" in which case, such representations
or warranties as so qualified shall have been breached in any respect),
covenant, obligation or agreement set forth in this Agreement or in any Related
Document and such breach shall not have been cured within 10 Business Days after
notice thereof is given by any Purchaser or Alliance (except that no cure period

of any of the representations or warranties in this Agreement or in any Related
Document, individually or in the aggregate, in any material respect (except for
representations and warranties which are qualified by their terms by a reference
to materiality or "Material Adverse Effect" in which case, such representations
or warranties as so qualified shall have been breached in any respect),
covenant, obligation or agreement set forth in this Agreement or in any Related

<PAGE>   50

        (d) either the Purchasers, Alliance or the Sellers, if the Closing shall
not have been consummated by September 15, 1998; or

        (e) either the Purchasers, Alliance or the Sellers, if any permanent
injunction or Order of a Governmental Entity preventing the Closing shall have
become final and nonappealable;

        (f) By either Parent or the Purchasers if, prior to the Closing Date,
(i) the Board of Directors of the Parent determines that a Third Party Proposal
for an Alternative Transaction constitutes a Superior Proposal, (ii) the Parent
promptly notifies the Purchasers of its determination in writing, which writing
shall set forth the terms and conditions of the Third Party Proposal and the
identity of the Person making the Third Party Proposal, (iii) ten days have
elapsed following receipt by the Purchasers of such written notice, (iv) during
such ten day period the Parent cooperates with the Purchasers with the intent of
enabling, but not obligating, the Purchasers to agree to a modification of the
terms and conditions of this Agreement so that the transactions contemplated
hereby may be effected, and (v) at the end of such ten day period, the Board of
Directors of the Parent continues to believe that such Third Party Proposal
constitutes a Superior Proposal and the Parent pays to the Purchasers the
amounts specified under Section 10.5(b) pursuant to the terms thereof. For
purposes of this Agreement, a "Superior Proposal" means any Third Party Proposal
to effect an Alternative Transaction; provided that (i) the Board of Directors
of the Parent determines in its good faith judgment (following the consultation
with, and the receipt of the advice of, the Parent's financial advisor) that
such Third Party Proposal is on terms that are more favorable to the Parent's
stockholders than the transactions contemplated by this Agreement (taking into
account all relevant factors, including the amount and form of consideration to
be received, the relative value of any non-cash consideration, and the timing
and certainty of closing) and (ii) the Board of Directors of the Parent
determines in its good faith judgment (based on the written advice of outside
counsel) that the failure to recommend or accept such Third Party Proposal would
violate the fiduciary duties of the Board of Directors of the Parent under
applicable Law;

provided, however, in each case, that none of the Sellers, Alliance nor the
Purchasers shall be entitled to terminate this Agreement if such party's breach
of this Agreement has prevented the satisfaction of a condition.  Any
termination pursuant to this Section 9.1 shall be effected by written notice
from the party or parties so terminating to the other parties hereto, which
notice shall specify the Section of this Agreement pursuant to which this
Agreement is being terminated.

9.2      EFFECT OF TERMINATION.

         In the event of the termination of this Agreement as provided in
Section 9.1, this Agreement shall be of no further force or effect, except for
Section 6.7, Section 10.5 and this Section 9.2, each of which shall survive the
termination of this Agreement; provided, however, that the Liability of any
party for any intentional, willful or knowing breach by



                                       49

such party of the representations, warranties, covenants, obligations or
agreements of such party set forth in this Agreement occurring prior to the
termination of this Agreement shall survive the termination of this Agreement
and, in addition, in the event of any action for breach of contract in the event
of a termination of this Agreement, the prevailing party shall be reimbursed by
the other party to the action for reasonable attorneys' fees and expenses
relating to such action.
