    Shares is deemed to be the aggregate of their market value.
(2) Pursuant to Rule 457(g) under the Securities Act of 1933, as amended, no

PROSPECTUS
 
                            1,732,000 COMMON SHARES
                   (INCLUDING 539,000 COMMON SHARES ISSUABLE
                         UPON THE EXERCISE OF WARRANTS)
                                      AND
                   WARRANTS TO PURCHASE 539,000 COMMON SHARES
 
                       AMERICAN SHARED HOSPITAL SERVICES
 
     The common shares, no par value ("Common Shares"), of American Shared
Hospital Services, a California corporation ("ASHS" and together with its
subsidiaries, the "Company"), warrants to purchase Common Shares ("Warrants")
and the Common Shares issuable upon exercise of such Warrants (collectively, the
"Securities") covered by this Prospectus may be sold from time to time by the
securityholders specified in this Prospectus or their successors in interest
(the "Selling Securityholders"). See "Selling Securityholders."
 
     On May 17, 1995, the Company repurchased $17,694,000 principal amount of
its senior subordinated notes from certain of the Selling Securityholders for
consideration comprised of cash, 819,000 Common Shares and 216,000 Warrants.
Pursuant to the terms of the Note Purchase Agreement dated as of May 12, 1995,
upon the occurrence of certain subsequent events the Company issued to such
Selling Securityholders an additional 374,000 Common Shares and 98,000 Warrants.
The repurchase of the senior subordinated notes was part of an overall financial
restructuring in which the Company also restructured most of its medical
equipment leases and issued its primary equipment lessor 225,000 Warrants. The
1,193,000 Common Shares, 539,000 Warrants issued in these transactions and
539,000 Common Shares underlying such Warrants are the Securities to which this
Prospectus relates. Such Securities are being registered by the Company under
the Securities Act of 1933, as amended (the "Act") pursuant to the terms of a
Registration Rights Agreement dated as of May 17, 1995 among the Company and the
Selling Securityholders (the "Registration Rights Agreement").
 
     The Common Shares are listed on the American Stock Exchange ("AMEX") under
the trading symbol "AMS." The Common Shares are also listed on The Pacific Stock
Exchange ("PSE"). Each such exchange has commenced a review procedure to
determine whether the Common Shares will remain listed. See "Risk
Factors -- Trading of Common Shares; Possible Delisting of Common Shares." On
October 20, 1995 the last reported sale price of the Common Shares on the AMEX
was $1.50 per share.
 
     The Company will not receive any of the proceeds from the sale of the
Securities being offered by the Selling Securityholders. The Selling
Securityholders may, from time to time, sell the Securities at market prices
prevailing on the AMEX or PSE, respectively, at the time of sale or sell the
Securities under certain other terms. See "Plan of Distribution."
 
THE SECURITIES ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF RISK. SEE "RISK
 FACTORS" FOR A DISCUSSION OF CERTAIN FACTORS WHICH SHOULD BE CONSIDERED IN
   CONNECTION WITH AN INVESTMENT IN THE SECURITIES OFFERED HEREBY.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
     AND EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE
        ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION
            TO THE CONTRARY IS A CRIMINAL OFFENSE.

                                  RISK FACTORS
 
     In addition to the other information and financial data set forth elsewhere
in this Prospectus, the following specific factors should be considered
carefully by prospective investors in evaluating the Company, its businesses and
an investment in the Securities.
 
DEFAULTS, POTENTIAL BANKRUPTCY AND RESTRUCTURING
 
     As a result of a serious cash shortage during the second half of 1992, the
Company failed to make the required semi-annual interest payments under its
14 3/4% Senior Subordinated Notes Due 1996 (the "14 3/4% Notes") and Senior
Subordinated Exchangeable Reset Notes Due 1996 (the "16 1/2% Notes") (the
14 3/4% Notes and the 16 1/2% Notes, collectively, are referred to as the
"Subordinated Notes") that were due beginning on October 15, 1992. In addition,
the Company suspended lease payments on a significant portion of its equipment
leases beginning on December 1, 1992.
 
     The non-payment of interest and the suspension of lease payments caused
defaults under the Company's Subordinated Notes and equipment leases and gave
the holders of such obligations as well as the lender under the Company's senior
secured working capital facility the right to declare all amounts immediately
due and payable and to reclaim substantially all of the Company's diagnostic
imaging equipment and other assets. The Company stated that if any of such
creditors or lessors had exercised their rights, the Company would have been
forced to seek a liquidation under Chapter 7 or a reorganization under Chapter
11 of the United States Bankruptcy Code.
 
     Following lengthy negotiations, the Company restructured its debt and most
of its lease obligations. See "The Company -- Financial Restructuring." The
restructuring had the effect of curing all defaults under the indentures
governing the Subordinated Notes and the equipment leases. The Company
nevertheless remains highly leveraged and has substantial fixed payment
obligations. If defaults occur in the future, the Company's creditors and
lessors would have the ability to accelerate the Company's obligations and seize
substantially all of its medical imaging equipment and other assets. There can
be no assurance that the Company will be able to avoid such defaults in the
future.
 
RECENT LOSSES; FINANCIAL CONDITION OF THE COMPANY
 
     The Company has reported significant operating losses in each of the last
three fiscal years. The net loss of the Company (after extraordinary items) was
$9,515,000, $15,644,000 and $5,175,000 for the years ended December 31, 1992,
1993 and 1994, respectively. The Company also reported a loss (before
extraordinary gain on early extinguishment of debt and a charge to reflect the
adoption of a new accounting standard) of $3,628,000 for the six month period
ended June 30, 1995. The Company had a net capital deficiency of $22,341,000 at
December 31, 1994 and $8,584,000 at June 30, 1995. The reduction in the net
capital deficiency at June 30, 1995 was due to an extraordinary gain of
$20,378,000 from the early extinguishment of debt at a discount. Unless the
Company is able to increase its revenues and/or increase its operating margins
through a reduction in its cost of operations, it will be unable to achieve
profitability. There can be no assurance that the Company will be profitable in
the future.
 
HIGH DEBT LEVEL
 
     Even following the restructuring, in which the Company was able to
repurchase at a significant discount and retire $17,694,000 principal amount of
Subordinated Notes, the Company remains highly leveraged. At June 30, 1995, the
Company had approximately $8,530,000 of long-term debt, $773,000 of Subordinated
Notes and approximately $25,800,000 of obligations under capital leases
($8,512,000 of which is due within one year). Scheduled payments under debt
obligations and capital leases are $6,031,000 during the last six months of 1995
and $12,501,000 during 1996. The Company's available cash flow during the first
six months of 1995 would have been insufficient to meet this level of cash
requirements. Accordingly, the Company during the next 18 months must increase
its revenues and reduce its cost structure in order to meet its obligations as
they become due. There can be no assurance that the Company will be able to meet
its scheduled obligations as they become due in the next 12 to 18 months.
Further, the high debt level may
 
                                        3
<PAGE>   7
 
adversely affect the Company's ability to offer technologically advanced
equipment in the future to customers, which may adversely affect the Company's
ability to secure or retain profitable contracts.
 
ACCESS TO CAPITAL AND FINANCING
 
     The Company is severely limited by covenants in its credit agreements from
incurring additional indebtedness without the consent of its lenders. In
addition, the Company has pledged substantially all of its liquid assets and
substantially all of its tangible personal property and real property to secure
its existing debt. As a result, the Company has very little financial
flexibility to address unforeseen cash needs, to fund future growth or to
finance necessary equipment purchases and upgrades.
 
NECESSITY TO REFINANCE MATURING INDEBTEDNESS
 
     A substantial portion of the Company's funded debt, including the
Subordinated Notes which mature in October 1996, will mature in 24 to 48 months.
During the last six months of 1995, and during 1996 and 1997, $4,377,000,
$10,411,000 and $8,655,000 plus the then outstanding balance (currently
approximately $3,200,000) of the New Revolver (as defined below) will come due.
The Company will not have sufficient cash resources to pay these obligations at
maturity. Accordingly, the Company will be required to seek new financing to
meet its maturing obligations. 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.
 
TRADING MARKET FOR COMMON SHARES; POSSIBLE DELISTING OF COMMON SHARES
 
     The Common Shares are currently traded on the American Stock Exchange and
The Pacific Stock Exchange. The announcement by the Company of the terms of a
restructuring in early April 1994 was followed by a significant decline in the
market price of the Common Shares. 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 of the Common Shares is also below the minimum
criteria for continued listing on such exchange. The closing per share price was
$1.625 at June 30, 1995. The Company has been advised that its net capital
deficiency is inconsistent with the criteria applied by the PSE for continued
listing on such exchange. The AMEX and PSE are currently reviewing the Company's
financial condition following the restructuring in order to determine whether
the Common Shares will continue to be listed on such exchanges. Accordingly, no
assurances can be given that a holder of Common Shares will be able to sell
Common Shares in the future on a national or regional securities exchange, or
that there will be an active trading market for the Common Shares or as to the
price at which the Common Shares might trade.
 
OFFER AND SALE OF SECURITIES MAY DEPRESS MARKET PRICE OF COMMON SHARES
 
     The Selling Securityholders may offer and sell Common Shares in a number of
different ways. See "Plan of Distribution." In the event that the Selling
Securityholders do not sell their Common Shares in an underwritten offering, the
offer and sale process may result in temporary disruptions in the market and
adversely affect the price of Common Shares. In any event, the availability of
the Securities (which represent approximately 30% of the fully diluted Common
Shares after exercise of the Warrants) for sale by the Selling Securityholders
may depress the market price of Common Shares for a significant period.
 
NO DIVIDENDS
 
     The Company is prohibited by its credit agreements from paying dividends on
the Common Shares and does not anticipate being in a position to pay dividends
for the foreseeable future.
 
CONTROL BY MAJOR SHAREHOLDERS
 
     As of October 6, 1995, Ernest A. Bates, M.D., the Company's Chairman of the
Board and Chief Executive Officer, owns 2,666,000 Common Shares through directly
owned shares and currently exercisable options, which represents approximately
46% of the Company's outstanding Common Shares. In addition, as a
 
                                        4
<PAGE>   8
 
   
result of Securities issued to them pursuant to the terms of the Note Purchase
Agreement, the Selling Securityholders own directly or through immediately
exercisable Warrants 1,732,000 Common Shares, representing approximately 37% of
the outstanding securities of the Company. (On October 6, 1995, The Board of
Directors increased the number of Directors, creating one vacancy to be filled
by an independent third party nominated by the holders of the Noteholder
Warrants, as defined below.) Thus, Dr. Bates and any of the Selling
Securityholders acting together will have the power to determine the outcome of
a shareholder vote with respect to any fundamental corporate transaction,
including mergers and the sale of all or substantially all of the Company's
assets. This could have the effect of blocking transactions that a majority of
the other shareholders would otherwise find attractive.
    
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's operations and business are dependent to a significant extent
upon the continued active participation of its founder, Chairman of the Board
and Chief Executive Officer, Ernest A. Bates, M.D. In the past, Dr. Bates has
personally guaranteed various financial obligations of the Company, which has
enabled the Company to secure insurance and obtain credit. Certain of the
Company's lenders have also sought to insure the continued involvement of Dr.
Bates by requiring his personal guarantee of a significant amount of the
Company's debt. Should Dr. Bates become unavailable to the Company for any
reason, it could have a material adverse effect on the Company's business,
results of operations, financial condition and prospects.
 
TECHNOLOGY
 
     Diagnostic imaging technology is subject to continuous development and
change. New technological breakthroughs may require the Company to acquire new
or technologically improved products to service its customers. There can be no
assurance that the Company's financial resources will enable it to make the
investment necessary to acquire such products. The failure to acquire or use new
technology and products could have a material adverse effect on the Company's
business and results of operations.
 
REIMBURSEMENT
 
     Customers to which the Company provides services generally receive payment
for patient care from governmental and private insurer reimbursement programs.
As a result, a significant adverse change in such reimbursement policies might
have a material adverse effect on the Company's business and results of
operations. As a result of federal cost-containment legislation currently in
effect, hospital in-patients covered by federally funded reimbursement programs
are classified into diagnostic related groups ("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. 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, and consequently many health care providers
have an incentive to use contract shared services on an out-patient basis. If
the DRG program is at some future date expanded to include out-patient
reimbursement, such change could have a material adverse effect on the Company's
business and results of operations.
 
RISK OF ADVERSE HEALTHCARE REFORM LEGISLATION
 
     In addition to extensive existing government healthcare regulation, there
are numerous initiatives at the federal and state levels for comprehensive
reforms affecting the payment for and availability of healthcare services,
including a number of proposals that would significantly limit reimbursement
under Medicare and Medicaid. It is not clear at this time what proposals, if
any, will be adopted or, if adopted, what effect such proposals would have on
the Company's business. Aspects of certain of these healthcare proposals, such
as cutbacks in the Medicare and Medicaid programs, containment of healthcare
costs on an interim basis by means that could include a short-term freeze on
prices charged by healthcare providers, and permitting greater state flexibility
in the administration of Medicaid, could adversely affect the Company. There can
be no assurance that any currently proposed or future healthcare legislation or
other changes in the administration or interpretation of governmental healthcare
programs will not have an adverse effect on the Company.

GOVERNMENT REGULATIONS
 
     Many aspects of the medical industry in the United States are subject to a
high degree of governmental regulation. Generally, failure to comply with any
such regulations may result in denial of the right to conduct business and
significant fines. For example, legislation in various jurisdictions requires
that health facilities obtain a Certificate of Need ("CON") prior to making
expenditures 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 equipment subject to CON requirements.
CON requirements vary from state to state as they apply to the operations of
both the Company and its customers. In some jurisdictions the Company is
required to comply with CON procedures before operating its services and in
other jurisdictions customers must comply with CON procedures before using the
Company's services. An increase in the complexity or substantive requirements of
such federal, state and local laws and regulations could adversely affect the
Company's business.
 
LABOR SHORTAGES
 
     Shortages of licensed technicians in the diagnostic imaging fields in
certain areas of the country could adversely affect the Company's labor costs in
those areas should the shortage become acute.
 
COMPETITION
 
     The Company faces severe competition from other providers of diagnostic
imaging services, some of which have greater financial resources than the
Company, and from 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 financial problems have adversely affected its ability to obtain
and retain certain profitable customer contracts, and its high debt burden may
adversely affect its ability to offer technologically advanced equipment in the
future. There can be no assurance that the Company will be able to retain its
competitive position in the medical imaging industry following the
restructuring.

                            FINANCIAL RESTRUCTURING
 
GENERAL
 
     On May 17, 1995, pursuant to the terms of the Note Purchase Agreement dated
as of May 12, 1995 (the "Note Purchase Agreement"), the Company repurchased (the
"Notes Repurchase") $17,694,000 principal amount of its Subordinated Notes from
certain holders for consideration consisting of $3,893,000 in cash, 819,000
Common Shares and immediately exercisable Warrants to purchase an additional
216,000 Common Shares, at an exercise price of $0.75 per share, representing 20%
and 5%, respectively, of the fully diluted Common Shares. Pursuant to the terms
of the Note Purchase Agreement, these holders were issued an additional 374,000
Common Shares and 98,000 Warrants following the approval by the Company's
shareholders of the grant to the Company's Chairman and Chief Executive Officer
of an option to purchase 1,495,000 Common Shares. The 1,193,000 Common Shares
and 314,000 Warrants issued as part of the Notes Repurchase, plus 225,000
Warrants issued pursuant to the Lease Restructuring (as defined below), and the
Common Shares issuable upon exercise of such Warrants, are the Securities to
which this Prospectus relates.
 
     The Notes Repurchase was the final event in a broad restructuring of the
Company's capital structure that commenced in mid-1992. As part of the
restructuring, the Company was able to amend most of the capital and operating
leases covering its medical equipment (the "Lease Restructuring") to reduce
monthly payments, eliminate $26,548,000 of indebtedness (including principal and
accrued and unpaid interest) through the Notes Repurchase and replace its
operating line of credit. On the date of the Notes Repurchase, the Company
entered into three new credit facilities totalling $8,000,000, which provided
funds for the Notes Repurchase and working capital, as well as term debt
reduction and the refinancing of certain medical equipment. As a result, the
Company was able to cure all existing defaults on its debt and equipment leases.
 
BACKGROUND
 
     Beginning in 1992, the Company experienced substantial declines in revenues
from its businesses. The revenue declines, which were caused by increased
competition and reduced acceptance of the services offered by the Company,
combined with high fixed payment obligations under existing equipment leases and
the Subordinated Notes, led to a serious cash shortage in the second half of
1992. During this period the Company concluded that revenues from its operating
activities would be insufficient to meet its fixed obligations and determined
that these obligations would have to be restructured.
 
     The Company failed to make the required semi-annual payments due under the
Subordinated Notes beginning on October 15, 1992. In addition, the Company
suspended lease payments on a significant portion of its leases beginning on
December 1, 1992. As a result of these actions, both the Subordinated Notes and
the equipment leases relating to substantially all of the Company's medical
imaging equipment were in default. This gave the holders of such obligations, as
well as the lender under the Company's secured working capital facility, the
right to declare all amounts immediately due and payable and, in the case of the
leases, reclaim substantially all of the Company's medical imaging equipment.
The Company stated that any such action by the holders would have forced the
Company to seek a liquidation under Chapter 7 or a reorganization under Chapter
11 of the United States Bankruptcy Code.
 
ELEMENTS OF RESTRUCTURING
 
     In light of the foregoing, the Company began negotiations in late 1992 to
restructure its equipment lease and debt obligations to more closely match
anticipated revenues and costs. These negotiations led to the Lease
Restructuring in December 1994, and the Notes Repurchase and replacement of the
Company's revolving credit facility in May 1995. Each of these events is
described below:
 
     1. Revolving Credit Facility.  The Company's previous revolving credit
facility provided for borrowings up to $5,000,000 based on a formula relating to
eligible accounts receivable and was secured by a lien on the accounts
receivable and inventory of CuraCare, Inc. ("CuraCare"), a Delaware corporation
which is a wholly-owned subsidiary of ASHS. During the period in which defaults
existed under the Subordinated Notes and equipment leases, the Company's
revolving credit lender gradually reduced the funds available to the
 
                                        8
<PAGE>   12
 
Company under the facility. On December 31, 1994, in connection with the sale of
a majority of the Company's respiratory therapy contracts and its respiratory
therapy registry, the Company provided cash collateral equal to the amount
borrowed under the revolving credit facility. The facility was repaid in full at
maturity on February 28, 1995.
 
     2. Lease Restructuring.  On December 30, 1994 (effective as of November 1,
1994 for most capital leases and January 1, 1994 for operating leases) the
Company and General Electric Company, a New York corporation acting through GE
Medical Systems ("GE Medical") entered into the Lease Restructuring.
 
     American Shared-CuraCare, a California general partnership ("AS-C") whose
partners are ASHS and a wholly-owned subsidiary of ASHS, is the entity through
which the Company leases its MRI medical imaging equipment. In the Lease
Restructuring, substantially all equipment financed by AS-C under capital leases
(the "Existing Capital Leases") for which GE Medical was the lessor were
restructured and after restructuring continue to meet the financial statement
accounting criteria under generally accepted accounting principles ("GAAP") to
be accounted for as capital leases. Under the restructured leases, scheduled
payments by AS-C provide for the retirement of the unpaid principal balance
under the Existing Capital Leases over the extended and restructured lease terms
which will expire on various dates between December 31, 1996 through December
31, 1999. AS-C will be entitled to purchase the leased equipment at its fair
market value, or to extend the relevant lease, at the end of the lease term, in
each case on terms offered by GE Medical at that time.
 
     All operating leases in effect at January 1, 1994 under which GE Medical
was the lessor of equipment to AS-C (the "Restructured GE Operating Leases")
were amended to extend and restructure the payment schedules. AS-C will be
entitled to purchase the leased equipment at its fair market value, or to extend
the relevant lease, at the end of the lease term, in each case on terms offered
by GE Medical at that time. As a result of the modification of lease terms, the
Restructured GE Operating Leases meet the financial statement accounting
criteria under GAAP to be accounted for as capital leases and are accounted for
as such. The present value of the net minimum lease payments on the Company's
capital leases was $25,812,000 as of June 30, 1995.
 
     As part of the Lease Restructuring, GE Medical converted various lease and
service payments that were due and unpaid, and a portion of the restructured
lease payments for the period from January 1, 1994 through March 31, 1994,
totalling approximately $3,000,000, into a $2,000,000 promissory note dated
January 1, 1995 (the "GE Note"). The GE Note was issued by AS-C to GE Medical
and is guaranteed by ASHS and certain of its subsidiaries. The GE Note will
mature in February 2002 and bears interest at a rate of 4% per annum. Monthly
payments of interest only are due through November 1995 and thereafter the
principal balance will amortize in 75 equal monthly installments until maturity.
The GE Note and the Company's guarantee are secured by a second priority lien on
the accounts receivable of ASHS and CuraCare and a first priority lien on
certain medical imaging equipment. The GE Note contains restrictive covenants
that limit the ability of the Company to incur debt, create liens, pay dividends
on the Common Shares, make capital expenditures, acquire or dispose of assets
and merge with other companies.
 
     In connection with the issuance of the GE Note, the Company issued GE
Medical on December 30, 1994 an immediately exercisable warrant (the "December
Warrant") to purchase 97,853 Common Shares for $0.01 per share until March 31,
1996. On May 17, 1995, an additional warrant was issued to purchase 127,147
Common Shares until September 30, 1996 (the "May Warrant", the December Warrant
and the May Warrant being collectively referred to as the "GE Warrants").
 
     3. Notes Repurchase and New Credit Facilities.  As described above, the
Notes Repurchase was consummated on May 17, 1995. The Notes Repurchase was the
culmination of over two years of negotiations between the Company and a small
number of holders who owned in the aggregate approximately 96% of the
Subordinated Notes. Prior to consummating the Notes Repurchase, the Company and
such holders had agreed to a restructuring (the "Prior Restructuring") in which
the holders would have exchanged their debt for new Common Shares that would
have given them an 89.4% ownership interest in the outstanding common equity of
ASHS. The Notes Repurchase was consummated in lieu of the Prior Restructuring.
 
                                        9
<PAGE>   13
 
     The Notes Repurchase was completed with the proceeds of three new credit
facilities. Concurrent with the Notes Repurchase on May 17, 1995, the Company
entered into a new revolving credit facility (the "New Revolver") with a
different lender than the previous revolving credit facility. Under the New
Revolver, the Company will have available up to $4,000,000 according to a
formula based on eligible accounts receivable. The New Revolver provides for
interest payments only (computed at the Bank of America prime rate plus 5%)
until maturity on May 17, 1997 when all amounts are due and payable. The initial
proceeds of $3,000,000 drawn under the New Revolver were used primarily to fund
the cash consideration in the Notes Repurchase. At September 30, 1995, the
Company had drawn $3,201,000 under the New Revolver and, based on eligible
accounts receivable, an additional $209,000 was available under the facility.
The New Revolver is secured by a first priority lien on all of AS-C's and
CuraCare's accounts receivable, certain equipment, inventory and general
intangibles and is guaranteed by ASHS and Ernest A. Bates, M.D., individually.
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 and inventory of AS-C and CuraCare and CuraCare's real property in
Modesto, California and a second priority lien on AS-C's and CuraCare'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.
 
   
     On May 17, 1995, the Company also entered into a $1,500,000 18-month level
amortizing 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 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
the Gamma Knife owned by the Company. The payments on this loan were
restructured in September 1995 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.
    
 
     In connection with the financing of the Notes Repurchase, the lenders that
provided the New Revolver and the Term Loan required a personal guarantee from
the Company's Chairman and Chief Executive Officer. In consideration of the
guarantee and of his continued service to the Company, the Chairman and Chief
Executive Officer was issued 184,000 Common Shares and, after obtaining
shareholder approval on October 6, 1995, an immediately exercisable 10-year
option to acquire 1,495,000 Common Shares for $0.01 per share.
 
                                USE OF PROCEEDS
 
     The Company will not receive any of the proceeds from the sale of the
Securities. All of the proceeds will be received by the Selling Securityholders.
See "Selling Securityholders." Upon exercise of any of the Warrants, the Company
shall receive proceeds equal to the aggregate respective exercise price in
return for the Common Shares.
 
                        DETERMINATION OF OFFERING PRICE
 
     The offering price of the Securities will be determined by the Selling
Securityholders in transactions entered into by them regarding the Securities.
See "Plan of Distribution."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
Comparison of Six Months Ended June 30, 1995 to Six Months Ended June 30, 1994
 
MEDICAL SERVICES REVENUES
 
     Medical services revenues of $17,140,000 for the six months ended June 30,
1995 represent a 12% decline compared to medical services revenues of
$19,451,000 for the six months ended June 30, 1994.
 
     Revenues from MRI for the six month period ended June 30, 1995 increased
$1,343,000 compared to the same period in the prior year. The increase was due
primarily to the commencement of new customer contracts and increased
utilization from contracts commenced in prior periods. The Company had a net
increase of approximately 14 new customer contracts as of June 30, 1995 compared
to June 30, 1994.
 
     CT revenues declined $395,000 for the six month period ended June 30, 1995
compared to the same period in the prior year due to the operation of two fewer
scanners and lower revenue generation from mobile routes. Nuclear medicine and
ultrasound revenues decreased $616,000 for the six month period ended June 30,
1995 compared to the same period in the prior year as a result of the December
31, 1994 sale by the Company of two ultrasound contracts as a part of its
respiratory therapy department contract sale and the continued decline in mobile
ultrasound usage.
 
     Respiratory therapy services revenues decreased $2,643,000 for the six
month period ended June 30, 1995 compared to the same period in the prior year
due to the sale of eight respiratory therapy contracts and the respiratory
registry in December 1994, and the termination of three contracts in the first
six months of 1995. During the remainder of 1995 an additional two contracts
will terminate.
 
     Gamma Knife revenues remained constant for the six month period ended June
30, 1995 compared to the same period in the prior year. Gamma Knife revenues are
currently not a significant component of the Company's revenues.
 
COST OF OPERATIONS
 
     Total Costs of Operations increased $1,208,000 for the six month period
ended June 30, 1995 compared to the same period in the prior year. The increase
in total costs of operations resulted primarily from the write-down of equipment
and deferred assets of $3,825,000. Medical services payroll, the largest routine
component of total costs of operations, decreased $1,742,000 for the six month
period ended June 30, 1995 compared to the same period in the prior year. The
decrease is primarily attributable to the Company's sale of certain respiratory
therapy contracts and the respiratory therapy registry during the fourth quarter
of 1994. Maintenance and supplies decreased $109,000 for the six month period
ended June 30, 1995 compared to the same period in the prior year. The decrease
is primarily attributable to pricing reductions on MRI maintenance contracts and
a decrease in supply usage associated with the sale and termination of
respiratory therapy contracts. Depreciation and amortization increased $658,000
for the six month period ended June 30, 1995 compared to the same period in the
prior year. The increase is primarily attributable to the Company's Lease
Restructuring with its primary equipment lessor which was effective January 1,
1994 but recorded cumulatively in the fourth quarter of 1994. Equipment leases
previously accounted for as rentals were accounted for as capitalized leases
(increased depreciation and interest expense) due to the Lease Restructuring.
Equipment rental decreased $1,107,000 for the six month period ended June 30,
1995 compared to the same period in the prior year as a result of the Lease
Restructuring. Other operating costs decreased $317,000 for the six month period
ended June 30, 1995 compared to the same period in the prior year primarily due
to a reduction in regional office and property related costs.
 
     In connection with the 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 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
 
                                       14
<PAGE>   18
 
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 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 determined by third parties and the recorded values of
certain assets. The impairment loss is comprised of a charge for the write-downs
of equipment and deferred assets of $3,825,000 (primarily MRI, CT and nuclear
medicine) and goodwill of $600,000.
 
SELLING AND ADMINISTRATIVE COSTS
 
     Selling and administrative costs decreased $67,000 for the six month period
ended June 30, 1995 compared to the same period in the prior year. The six month
period ended June 30, 1995 results would have reflected a higher decrease in
expenses except for a second quarter 1995 charge of $265,000 to salary and wage
expense for the 184,000 Common Shares issued to the Company's Chairman and Chief
Executive Officer, Ernest A. Bates, M.D., for his continued services to the
Company and his personal guarantee of $6,500,000 of indebtedness of the Company.
See "Liquidity and Capital Resources".
 
INTEREST EXPENSE
 
     Interest expense increased $192,000 for the six month period ended June 30,
1995 compared to the same period in the prior year. The increase is primarily
due to the Lease Restructuring and utilization of a new credit facility
commencing May 17, 1995 (see "Liquidity and Capital Resources"), offset by the
reduction in interest from the Notes Repurchase on May 17, 1995 (see "Liquidity
and Capital Resources") and the repayment of the Company's revolving credit
facility on February 28, 1995. In addition, the GE Warrants issued on May 17,
1995 resulted in a charge to interest expense of $167,000.
 
INCOME (LOSS) BEFORE INCOME TAXES AND EXTRAORDINARY ITEM
 
     The Company had a loss before extraordinary items of $8,053,000 for the six
month period ended June 30, 1995 as compared to a loss of $3,685,000 for the
same period in the prior year. Included in the Company's loss for the six month
period ended June 30, 1995 was a charge of $4,425,000 due to adoption of FAS
121.
 
NET INCOME
 
     The Company had net income of $12,325,000 for the six month period ended
June 30, 1995 compared to a net loss of $3,685,000 for the same period in the
prior year. The Company's net income for the six month period ended June 30,
1995 included an extraordinary gain of $20,378,000 on its debt restructuring
recorded on May 17, 1995. The gain resulted from the repurchase of $17,694,000
of face amount plus $8,854,000 of accrued and unpaid interest of the
Subordinated Notes net of cash, Common Shares and Warrants issued, and
transaction related costs of $3,893,000, $1,250,000 and $1,027,000 respectively.
 
Comparison of 1994 to 1993 and 1993 to 1992
 
MEDICAL SERVICES REVENUES
 
     Medical services revenues decreased 2.4% in 1994 compared to 1993 and
decreased 19.1% in 1993 compared to 1992. The 2.4% and 19.1% decreases in 1994
and 1993, respectively, were caused primarily by an 18% decrease ($1,398,000) in
respiratory therapy revenues in 1994 and a 19% decrease ($6,891,000) in
diagnostic imaging services revenues in 1993.
 
     MRI revenues increased 11% ($2,223,000) in 1994 compared to 1993 and
decreased 12% ($2,859,000) in 1993 compared to 1992. The increase in 1994
compared to 1993 was primarily due to the commencement of new customer contracts
and increased utilization from contracts commenced in 1993. The decrease in 1993
compared to 1992 was due to the termination of services at three fixed site
locations and a decline in revenues
 
                                       15
<PAGE>   19
 
from the mobile MRI units. MRI revenues from mobile units decreased due to the
termination of certain long standing contracts and the replacement of those
contracts with new contracts with lower pricing and procedure volumes. In
addition, the marketing time required to replace terminating customers
lengthened because of increased competition and the fact that more health care
providers already had access to MRI services. Revenues were also negatively
impacted by delays in the commencement of replacement contracts due to
regulatory and site improvement delays and termination notification periods
which certain customers were obligated to provide to previous providers. MRI
revenues as a percentage of total medical services revenues were 59%, 52% and
48% in years 1994, 1993 and 1992, respectively.
 
     The Company's non-MRI diagnostic imaging services revenues declined 19%
($1,905,000) in 1994 compared to 1993 after a 29% ($4,032,000) decrease in 1993
compared to 1992. The decline in both years was attributable to decreased CT
revenue from the reduction in the CT fleet by two scanners in 1994 and three
scanners in 1993, lower revenue generated on mobile routes, reductions in per
study wholesale prices and competition. The Company has had to convert the
majority of its CT fleet from higher revenue and cost mobile routes to lower
revenue and cost interim rental placement units to maintain utilization.
Revenues from CT operations decreased $1,170,000 in 1994 and $2,209,000 in 1993
from 1992 revenues of $7,395,000. In addition, nuclear medicine and ultrasound
revenues decreased in 1994 compared to 1993 and in 1993 compared to 1992 as a
result of the Company's continued de-emphasis of mobile nuclear and ultrasound
contracts and the expiration of one in-house ultrasound contract in 1994 and
four ultrasound contracts in 1993. The decrease in nuclear medicine and
ultrasound revenues was $735,000 in 1994 and $1,823,000 in 1993 from a 1992
revenue base of $6,560,000. Non-MRI diagnostic imaging services revenues as a
percentage of total medical services revenues was 21%, 25% and 29% for the years
ended 1994, 1993 and 1992, respectively. The Company on December 31, 1994 sold
two ultrasound department contracts as a part of its respiratory therapy
department contract sale. These contracts had 1994 revenues of approximately
$850,000.
 
     Respiratory therapy services revenues in 1994 decreased $1,398,000 compared
to 1993 due to the termination of six contracts at various periods during 1993.
Revenues in 1993 decreased $2,415,000 from 1992 primarily due to the termination
of six contracts. The Company on December 31, 1994 sold eight respiratory
therapy department contracts and its respiratory therapy registry which had
aggregate revenues in 1994 of approximately $5,300,000.
 
COST OF OPERATIONS
 
     The Company's cost of operations, consisting of payroll, maintenance and
supplies, depreciation and amortization, equipment rental, other operating
expenses (such as vehicle fuel, building rents, regional office costs,
insurance, property taxes, bad debt expense, fees and training expenses), and
write-down of equipment decreased in absolute dollars both in 1994 and 1993
compared to prior years.
 
     Medical services payroll costs decreased by $1,158,000 in 1994 compared to
1993 and $2,431,000 in 1993 compared to 1992 and remained constant as a percent
of medical services revenues (27% in 1994, 29% in 1993, 28% in 1992). The
medical services payroll cost decline was due to the continued decrease in labor
intensive (Respiratory Therapy, mobile CT, Ultrasound, Nuclear Medicine) service
revenues due to contract expirations and termination of marginally profitable
and unprofitable contracts.
 
     Depreciation and amortization increased $1,789,000 in 1994 compared to
1993. The increase in depreciation was primarily due to the impact of the Lease
Restructuring. Effective January 1, 1994, equipment leases previously accounted
for as rentals are accounted for as capitalized leases due to the Lease
Restructuring. Secondarily, depreciation increased due to the full year's impact
of depreciation on capital expenditures related to upgrades performed on certain
MRI units in the last half of 1993. Depreciation and amortization decreased
$1,040,000 in 1993 compared to 1992 primarily due to equipment acquired in the
CuraCare acquisition in October 1987 being depreciated to salvage value during
1992 and 1993 and suspension of depreciation for certain MRI systems while in
upgrade.
 
     The Company's maintenance and supplies costs were 20%, 19%, and 19% as a
percent of medical service revenues in 1994, 1993, and 1992, respectively.
Maintenance and supplies costs increased $377,000 in 1994 compared to 1993 and
decreased $1,961,000 in 1993 compared to 1992. The increase in 1994 was
primarily
 
                                       16
<PAGE>   20
 
attributable to equipment aging and additional equipment utilization. The
decrease in 1993 was primarily attributable to improved pricing on MRI
maintenance contracts. In addition, cost reductions were achieved in both 1994
and 1993 due to reduced medical supplies costs associated with fewer respiratory
therapy contracts and fixed site MRI units and improved pricing on MRI cryogen
supply contracts.
 
     Equipment rental as a percentage of medical services revenue was 4% in
1994, 13% in 1993 and 8% in 1992. The decrease in equipment rental of $3,487,000
in 1994 compared to 1993 was primarily attributable to the Lease Restructuring
in which equipment previously accounted for as rentals, effective as of January
1, 1994, is being accounted for as capitalized leases and to less reliance on
interim equipment rentals. The increase in equipment rental of $891,000 in 1993
compared to 1992 was primarily attributable to the addition of one operating
lease, several MRI units under short term rental and the full year's impact in
1993 of the two operating leases entered into in 1992.
 
     Other costs of operations as a percentage of medical services revenue was
13%, 13% and 11% in 1994, 1993 and 1992, respectively. The $4,000 decrease in
1994 was due to the continued reduction in regional office costs. The $546,000
decrease in other costs in 1993 was due primarily to the continued reduction in
regional office costs, building rent and relocation costs related to certain
fixed site MRI units.
 
   
     In the fourth quarter of 1993 and the third and fourth quarters of 1992,
the Company wrote down the carrying value of certain equipment to estimated net
realizable value which reflects its future estimated income producing capacity.
In 1993, the write-down of $443,000 resulted from the decline in market
acceptance of two of the Company's less technologically advanced MRI units.
Efforts to re-market these units have been unsuccessful. In 1992, the write-down
resulted from the decline in market acceptance of five of the Company's less
technologically advanced MRI units, six CT units and certain ultrasound and
nuclear medicine equipment. After efforts to remarket these units during 1992,
it became evident that there was a permanent impairment in their estimated net
realizable value. The write-downs resulted in a charge to operations of
$3,454,000 for the year ended December 31, 1992.
    
 
SELLING AND ADMINISTRATIVE COSTS
 
     The Company's selling and administrative costs decreased $849,000 in 1994
compared to 1993 and increased $547,000 in 1993 compared to 1992. The decrease
in 1994 was primarily attributable to a reduction in the costs associated with
the fourth quarter of 1993 write-down of intangible assets associated with the
Company's CuraCare acquisition, reduced travel related expenses and building
rent. The increase in 1993 compared to 1992 was due to the increase in sales
force initiated in the second half of 1992 in recognition of the more
competitive MRI environment, costs associated with a reduction in force,
relocation of the corporate office and restructuring fees totalling $340,000.
 
INTEREST EXPENSE
 
     The Company's interest expense increased by $671,000 in 1994 compared to
1993 due to the Lease Restructuring in which equipment previously accounted for
as rentals is treated as capitalized leases effective January 1, 1994.
 
     The Company's interest expense decreased by $768,000 in 1993 compared to
1992. The decrease occurred due to the maturation of existing equipment leases
and long-term debt and the replacement of three MRI units sold or returned at
lease maturity with two MRI units under capital lease financing.
 
WRITEDOWN OF INTANGIBLE ASSETS
 
     During 1993, the Company's management continued to evaluate the
realizability of intangible assets associated with its acquisition of CuraCare.
CuraCare operates substantially all of the Company's non-MRI businesses,
including CT, Respiratory Therapy, Ultrasound and Nuclear Medicine. Revenues and
operating profits from CuraCare have continued to decline significantly over the
past few years despite strategic plans implemented by management. During the
fourth quarter of 1993, the Company's management determined it was unlikely that
the Company's non-MRI businesses would have significant growth potential in the
 
                                       17
<PAGE>   21
 
foreseeable future. The Company's management, therefore, reduced the operational
management and sales force for its non-MRI businesses.
 
     The changing health care environment and reduced barriers of entry due to
decreased equipment costs for non-MRI businesses contributed to losses in 1992
and 1993. The Company determined, based on its methodology of evaluating the
recoverability of intangible assets, that the forecasted cash flow for non-MRI
businesses did not support the future amortization of the intangible asset
balance of $5,308,000 at December 31, 1993, for these modalities.
 
     The Company projected forward its results from operations, and cash flows,
including interest expense, for five years to analyze the recoverability of its
intangible assets. In formulating the financial forecasts, the Company
considered historical trends, current market conditions and potential new trends
and their impact on revenues. Based on these forecasts it was determined that
the cumulative results of operations and cash flows for non-MRI businesses were
inadequate to recover any portion of the intangible asset balance associated
with CuraCare. Accordingly, the Company wrote-down the intangible asset balance
of $5,308,000 in the fourth quarter of 1993. The Company's remaining intangible
asset balance of $2,118,000 at December 31, 1994 related primarily to its MRI
business.
 
GAIN ON SALE OF ASSETS
 
     The gain on sale of assets of $3,294,000 in 1994 was primarily due to a
gain of $3,199,000 on the sale of certain respiratory therapy contracts. The
sale resulted in the Company receiving cash of approximately $4,000,000 and the
buyer assuming approximately $300,000 in liabilities. Gain (Loss) on sale of
equipment fluctuates depending on the timing of asset dispositions. The Company
continued selling non-essential assets during 1994.
 
INTEREST AND OTHER INCOME
 
     Interest and other income decreased $644,000 in 1994 compared to 1993
because during 1993 the Company's insurance carrier paid a business interruption
insurance claim of $575,000 for lost MRI service revenues in the United Kingdom.
Interest and other income increased in 1993 compared to 1992 primarily due to
the business interruption insurance payment.
 
INCOME TAX PROVISION
 
     The 1994, 1993 and 1992 amounts relate to miscellaneous payments and
refunds of federal and state income taxes and adjustments of amounts paid and
accrued in prior years.
 
NET LOSS
 
     The 1994 net loss of $5,175,000 was primarily attributable to a continued
decline in medical services revenues without a corresponding reduction in
operating costs, partially offset by the gain on the sale of respiratory therapy
contracts.
 
     During September 1994, the Company recognized an extraordinary gain on the
early extinguishment of indebtedness of $362,000. The extraordinary gain
resulted from the repurchase of $321,000 face amount plus $115,000 of accrued
and unpaid interest of the Company's 14 3/4% Notes, net of income tax and
deferred financing costs of $10,000, for $64,000 in cash.
 
     The 1993 net loss of $15,644,000 was primarily attributable to the
significant reduction in medical services revenues, the write-down of intangible
CuraCare assets and interest on the Subordinated Notes.
 
     The 1992 net loss of $9,515,000 was primarily attributable to the
significant reduction in medical services revenues, the write-down of equipment
and interest payments on the Subordinated Notes.

BALANCE SHEET DATA
 
Liquidity and Capital Resources
 
     The Company had cash and cash equivalents of $461,000 at June 30, 1995
compared to $1,225,000 at December 31, 1994. The Company's cash position
decreased in 1995 as a result of its operating losses.
 
     On May 17, 1995, the Company repurchased for cash and securities
approximately 96% of its outstanding Subordinated Notes. The Notes Repurchase,
together with the December 1994 Lease Restructuring and the availability of up
to $8,000,000 of new debt financing, concluded restructuring the Company's
obligations.
 
     In 1992, the Company determined that it would not generate sufficient
revenues or achieve sufficient expense reductions to meet in full its scheduled
debt and lease obligations. Accordingly, the Company suspended interest payments
under the Subordinated Notes beginning with the October 15, 1992 semi-annual
interest payment and suspended lease payments on a significant portion of its
equipment leases from December 1, 1992. As a result, the Company was in default
under substantially all of its debt and lease obligations and the holders had
the right to accelerate such obligations. The Company stated that any such
acceleration would cause it to seek a liquidation in bankruptcy.
 
     The Company engaged in restructuring negotiations with its creditors
following the actions referred to in the immediately preceding paragraph. As a
result of these negotiations, the Company restructured certain of its
outstanding obligations as described below.
 
     1. Secured Credit Facility.  The Company's revolving credit facility was
repaid in full and terminated on February 28, 1995 with a portion of the
proceeds of the sale of eight respiratory therapy contracts. The New Revolver
was entered into in May 1995 in connection with the Notes Repurchase.
 
     2. Equipment Leases.  On December 30, 1994, the Company entered into the
Lease Restructuring. Under the Lease Restructuring, the leases covering
substantially all of the Company's medical equipment were modified to extend the
lease terms and to reduce scheduled lease payments. During 1994, the Company
made monthly aggregate payments based on the estimated restructured lease
payments. In addition, certain accrued and unpaid lease and service payments
were converted into the GE Note, a $2,000,000 secured seven year note. The GE
Note bears interest at an annual rate of 4%, payable in arrears, and will mature
in February 2002. Monthly payments of interest only are due through November,
1995. Thereafter the principal balance of the GE Note will amortize in 75 equal
monthly installments until maturity. The GE Note is secured by a lien on the
accounts receivable of CuraCare and AS-C. The GE Note is also secured by a lien
on two CT units and one Ultrasound unit.
 
     In connection with the issuance of GE Note, the Company issued the GE
Warrants to purchase an aggregate of 225,000 Common Shares for $0.01 per share.
 
     3. Subordinated Notes.  On May 12, 1995, in lieu of a previously negotiated
restructuring that would have resulted in the exchange of approximately 96% of
the Subordinated Notes for new common shares that would have represented
approximately 89.4% of the Company's common equity, the Company agreed to
repurchase such Subordinated Notes (including accrued and unpaid interest) for a
combination of cash and equity securities equal to approximately 25% of the
Company's fully diluted shares. On May 17, 1995 the Company completed the Notes
Repurchase. After giving effect to certain subsequent adjustments, these holders
received $3,892,681 in cash, plus a total of 1,193,000 Common Shares (equal to
approximately 20% of ASHS's fully diluted Common Shares), and Warrants for an
additional 314,000 Common Shares (equal to approximately 5% of the fully diluted
Common Shares). The Warrants are immediately exercisable at $0.75 per share.
 
     The Restructuring results in annual interest savings related to the
Subordinated Notes of approximately $2,890,000. After the Restructuring there
remain outstanding approximately $773,000 principal amount of Subordinated Notes
that mature in October 1996 with required annual interest payments of $125,000.
The Company paid accrued and unpaid interest through April 15, 1995 of
approximately $460,000 to holders of Subordinated Notes that were not purchased
on May 17, 1995. The subsequent semi-annual interest payment due October 15,
1995 was paid timely by the Company.
 
                                       19
<PAGE>   23
 
   
     The Notes Repurchase was completed with the proceeds of the Term Loan, New
Revolver and the Gamma Knife Loan. The Term Loan is a 48 month level amortizing
loan of $2,500,000 at an annual interest rate of 15%. The Term Loan is secured
by various unencumbered equipment, CuraCare's Modesto real property and certain
accounts receivable. The proceeds were used to repurchase the Subordinated
Notes, refinance certain equipment and provide working capital. The New Revolver
is a two year, $4,000,000 interest only revolving credit facility at Bank of
America prime lending rate plus 5%. The New Revolver is secured by AS-C's and
CuraCare's accounts receivable and had a balance of $3,201,000 as of September
30, 1995. The proceeds were used to repurchase Subordinated Notes. The Company
had additional borrowing capacity under its revolving credit facility, based on
its eligible accounts receivable valuation, of $209,000 at September 30, 1995.
The Gamma Knife Loan is an 18 month level amortizing loan of $1,500,000 at an
annual interest rate of 10.5%. The proceeds were utilized to refinance the
Company's Gamma Knife and provide additional working capital. The payments on
this loan were restructured in September 1995 from $90,431 per month to $40,203
per month, effective September 17, 1995, and to extend the loan term until
September 17, 1998.
    
 
     At the Company's annual shareholder meeting held on October 6, 1995, the
Company's shareholders approved the issuance of an option for additional Common
Shares to Dr. Bates 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. As a result of this issuance, Dr. Bates held approximately 46% of
the Company's then fully diluted outstanding shares and the Selling
Securityholders received additional shares and warrants to maintain their
respective fully diluted ownership of the Common Shares. Existing shareholders
own approximately 30% of the Common Shares, fully diluted.
 
   
     The various restructuring transactions described above cured all of the
Company's 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 cash
equipment lease payments during the 12 months from July 1995 to June 1996 are
$10,778,000 and scheduled interest and principal payments under the Company's
other loan obligations during such period are approximately $2,167,000. The
Company's revenues during the first six months of 1995 were not sufficient to
make these payments. In addition, the Company has loan and other debt maturities
of approximately $10,692,000 due prior to October 31, 1996 and an additional
$8,359,000 due and the outstanding balance (currently approximately $3,200,000)
of the New Revolver prior to October 31, 1997. Accordingly, the Company during
the 12 months from July 1995 to June 1996 must increase its revenues and reduce
its cost structure, and secure refinancing, in order to meet its obligations as
they become due. There can be no assurance that the Company will be able to meet
its scheduled obligations during the next 12 months.

                                    BUSINESS
 
GENERAL DEVELOPMENT
 
     The Company provides shared diagnostic imaging services to approximately
224 hospitals, medical centers and medical offices located in 20 states and one
hospital in the United Kingdom. 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 a Gamma
Knife to a major university medical center and has an option to acquire a second
Gamma Knife located in another major university medical center.
 
     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. 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 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, Inc., ASHS's co-venturer in AS-C, from Tenet for
$4,200,000. MMRI's only asset is its 50% interest in AS-C.
 
     In November 1990 the Company started a new wholly owned subsidiary,
European Shared Medical Services Limited, an English registered company, to
provide MRI services in the United Kingdom. In addition, in August 1993, the
Company incorporated a new wholly owned subsidiary in California, American
Shared Radiosurgery Services, to provide Gamma Knife services.
 
     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
Therapy Registry for approximately $4,000,000 in cash plus the assumption by the
buyer of $300,000 in liabilities and agreed that it would no longer compete in
such business.
 
   
     In June 1995, ASHS 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 the state of California.
    
 
     On October 17, 1995, ASHS, through its wholly owned subsidiary, American
Shared Radiosurgery Services ("ASRS") and Elekta AB, through its wholly owned
United States subsidiary, GKV Investments, Inc., a Georgia corporation ("GKV"),
entered into an agreement to form GK Financing, LLC, a limited liability company
to provide alternative financing of Elekta Gamma Knife units in the United
States and Brazil. See "Gamma Knife Joint Ventures."
 
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 diagnosis can often be performed on a 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 to
approximately 224 health care providers including hospitals, clinics and
physicians' offices located in 20 states and the United Kingdom. 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
 
                                       21
<PAGE>   25
 
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. Non-MRI diagnostic imaging services revenues as a
percentage of total medical services revenues were 21%, 25% and 29% in 1994,
1993, 1992, respectively. Following the sale of a substantial portion of its
respiratory therapy contract management business in December 1994, the portion
of the Company's revenues provided by non-MRI diagnostic imaging services is
expected to decline. For the six month period ended June 30, 1995, non-MRI
diagnostic imaging services revenues as a percentage of total medical services
revenues were 20%. See "Management's Discussion and Analysis -- Total 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 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 MRIs 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, 1994, 19 of such units are 1.5 Tesla units, three are 1.0 Tesla units, and
five are 0.5 Tesla units. All 27 of the MRI units are mobile or transportable.
In addition, the Company has two 1.5T less technologically advanced fixed site
MRI units for sale. The Company had 104 MRI customers at December 31, 1994
compared to 90 customers as of December 31, 1993. In addition, effective January
5, 1995 the Company entered into a management agreement with an equipment
leasing company to manage three of its mobile MRI units. MRI revenues constitute
59%, 52% and 48% of total medical services revenues in years 1994, 1993 and
1992, 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 operates 16 CT units, 15 of which
are housed in specially designed mobile vans serving one or more hospitals and
one of which is a fixed-site unit. CT utilizes multiple X-Ray beams and
detectors to derive information which 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 lumbo-sacral spine, 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
 
                                       22
<PAGE>   26
 
were approximately 10% of medical services revenues in 1994 and 13% and 15% in
1993 and 1992, respectively.
 
     Ultrasound and Nuclear Medicine.  The Company owns and operates
approximately 30 systems providing ultrasound and nuclear medicine services.
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 physician to
establish the presence or absence of disease. Nuclear medicine not only provides
an anatomic image but also provides functional information which cannot be
provided by MRI or CT.
 
     Nuclear medicine services of the Company are primarily composed of Single
Photon Emission Computed Tomography ("SPECT") wherein radioisotopes are injected
into the patient and the patient is subsequently imaged by a camera which 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 both a
shared service and full-time 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. Ultrasound
and nuclear medicine revenues were approximately 10% of medical services
revenues in 1994 and 12% and 13% in 1993 and 1992, respectively.
 
GAMMA KNIFE
 
     The Company's first Gamma Knife, which is operated at a major university
medical center on a fee-per-procedure basis, commenced operation in September
1991. The Gamma Knife treats certain vascular malformations and intracranial
tumors without surgery.
 
     In January 1993, the Company entered into a purchase agreement with the
manufacturer for $2,900,000 plus sales tax on its second Gamma Knife and a
fee-for-service lease with another university medical center. During 1993, the
Company advanced $1,090,000 to the equipment manufacturer. Included in this
amount was $800,000 advanced by a third party lessor and guaranteed by the
Company's Chairman and Chief Executive Officer. The Company was unable to fund
the next required advance payment and was notified by the manufacturer that the
Company was in default under the provisions of the purchase agreement.
 
     On April 6, 1994, the Company's agreements to purchase the Gamma Knife from
the manufacturer and lease the Gamma Knife to such university medical center
were formally terminated. Settlement of these agreements entailed the payment of
$130,000 in interest and costs to the manufacturer and the university medical
center. The Company's Chairman and Chief Executive Officer simultaneously agreed
to enter into substantially identical purchase and lease obligations as those
previously executed by the Company. On April 6, 1994 new purchase and lease
agreements were entered into by the Company's Chairman and Chief Executive
Officer and the manufacturer and the university medical center. Of the
$1,090,000 in advances previously paid to the manufacturer, $800,000 was
refunded to the third party lessor and $290,000 (less certain settlement costs)
was refunded to the Company and the Company simultaneously advanced $290,000 to
the Chairman and Chief Executive Officer who executed a Promissory Note. As of
September 30, 1995, the balance outstanding on the Promissory Note was
approximately $262,000. The Promissory Note is repayable over 60 months
including interest at 6% per annum. Concurrently, the third party lessor agreed
to fund the remaining $2,610,000 purchase price of the Gamma Knife on behalf of
the Chairman and Chief Executive Officer and the Company received an option to
purchase the Gamma Knife. The option entitles the Company to purchase the Gamma
Knife from its Chairman and Chief Executive Officer for an amount equal to the
remaining debt obligation associated with the Gamma Knife plus costs and losses,
if any, incurred by the Chairman and Chief Executive Officer, when the Company
is able to obtain financing for this purchase. The Gamma Knife became
operational on August 3, 1994.

GAMMA KNIFE JOINT VENTURE
 
   
     ASHS, through ASRS, a California corporation, and Elekta Holdings U.S.,
Inc., through its wholly owned subsidiary, GKV, entered into an agreement on
October 17, 1995 to form GK Financing, LLC ("GKF"), a California limited
liability corporation. In exchange for a 78% ownership interest held by ASRS in
GKF the Company will contribute two Gamma Knives (each subject to a financing
lease) and the respective leases relating thereto to GKF. GKV will contribute
$800,000 for a 22% ownership interest in GKF and lend 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. Financing by GKV will most likely
occur when an alternative payment method such as a fee-for-service arrangement
is desired. GKF has placed orders for four new Gamma Knife systems.
    
 
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. 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 acquire newer, more advanced replacement equipment when appropriate.
 
     During the normal course of business, the Company has customer contracts
which 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.
 
     The Company employed at the end of 1994 eight sales and marketing and four
operational managers located in the Western, Southeastern, and Midwest regions
of the country. 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 1994 nor for the Company's revenues for each of the
first and second fiscal quarters of 1995.
 
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,
 
                                       24
<PAGE>   28
 
some of which may have greater financial resources than those of the Company,
and from 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. Adverse
market conditions have significantly impacted providers of mobile services of
which there are only approximately five operating on a national basis. Those
with greater financial resources are better able to withstand adverse market
conditions.
 
     Competition in the MRI service industry has increased since 1992 due to
deterioration of market conditions in that industry. Recent deterioration is
based partly upon a temporary increase in purchases of MRI units by physician
partnerships in the late 1980s and early 1990s, which has largely been halted by
legislation that limits self-referrals. The increased competition among MRI
equipment manufacturers has resulted in greater availability to end users of new
imaging equipment from manufacturers at more competitive pricing than
contracting with full-service providers such as the Company.
 
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, and consequently many health
care providers have an incentive to use contracted shared services on an
out-patient basis. 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 has 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.
 
     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, or induce the
purchase, lease, order, or arrangement or the recommendation for the purchase,
lease on order of items or services, in each case for which payment may be made
under the Medicare and Medicaid programs and certain other government funded
programs. The Social Security Act provides authority to the Office of Inspector
General through civil proceedings to exclude an individual or entity from
participation in the Medicare and state health programs if it is determined any
such party has violated Section 1128B(b) of the Social Security Act. The Company
believes that it is in compliance with the federal anti-kickback statute.
Additionally, the Omnibus Budget Reconciliation Act of 1993, often referred to
 
                                       25
<PAGE>   29
 
as "Stark II" bans physician 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 believes
that it is in compliance with the Physician Ownership and Referral Act of 1993.
The Company cannot determine what impact this legislation (which applies to all
payors) will have upon 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 has passed all such reviews. The Company's other services
are not generally subject to inspection or review by regulatory bodies.
 
     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.
 
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 September 30, 1995, the Company employed approximately 200 employees on
a full-time basis and approximately 130 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.

                                   PROPERTIES
 
     The Company owns approximately two acres of land and 27,000 square feet of
office and warehouse space located thereon in Modesto, California. Title to the
property has been pledged to secure its obligations under the Term Loan.
 
     The Company's corporate offices are located at Four Embarcadero Center,
Suite 3620, San Francisco, California where it leases 2,996 square feet for
$7,740 per month. This lease runs through September 1999.
 
   
     An additional property leased by the Company principally for field
operations and sales support is located in West Chicago, Illinois. The Company's
Tennessee office was closed in March 1995.
    
 
     For the year ended December 31, 1994 and the six month period ended June
30, 1995, the Company's aggregate net rental expenses for all properties and
equipment were approximately $2,326,000 and $1,500,000 respectively.
 
                               LEGAL PROCEEDINGS
 
     There are no material pending legal proceedings involving the Company or
any of its property. The Company knows of no legal or administrative proceedings
against the Company contemplated by governmental authorities.

        MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S COMMON SHARES
 
     The Common Shares are currently traded on the AMEX and PSE. The
announcement by the Company of the terms of the Prior Restructuring in early
April 1994 was followed by a significant decline in the market price of the
Common Shares. 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 $1.625 at June 30, 1995. The Company has been
advised that its net capital deficiency is inconsistent with the criteria
applied by the PSE for continued listing on such exchange. The AMEX and PSE are
currently reviewing the Company's financial condition following the
restructuring 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 ASHS on the American Stock Exchange Consolidated Reporting
System for each full quarter for the last two fiscal years.

1995 STOCK OPTION PLAN
 
     On August 15, 1995, the Board of Directors approved the Company's 1995
Stock Option Plan (the "1995 Plan") providing for non-qualified stock options
and "incentive stock options," subject to approval by the Company's
shareholders. At the 1995 Annual Meeting held on October 6, 1995, the
shareholders approved the 1995 Plan. Under the 1995 Plan, 330,000 Common Shares
have been reserved for awards to officers and other key employees, non-employee
directors, and advisors subject to adjustment in the event of a stock split,
stock dividend, recapitalization, reorganization, merger or other similar event
or change in capitalization. Approximately six employees and five non-employee
directors are eligible to participate in the 1995 Plan. Any person who
beneficially owns more than 15% of the outstanding Common Shares is not be
eligible to participate in the 1995 Plan.
 
     The 1995 Plan is administered by the Stock Option Committee of the Board of
Directors (the "Committee") which determines when options become exercisable,
provided that no option shall be exercisable later than ten years after its date
of grant. Options may be exercised during the lifetime of the optionee only by
such optionee and are not transferable other than by optionee's will or by the
laws of descent or distribution or pursuant to beneficiary designation
procedures specified in the 1995 Plan.
 
     Upon shareholder approval, the 1995 Plan became effective as of August 15,
1995 and will terminate ten years thereafter, unless terminated earlier by the
Board of Directors. The Board of Directors may amend the 1995 Plan at any time
except that, without the approval of the shareholders of the Company, no
amendment may, among other things, (i) increase the number of Common Shares
available under the 1995 Plan, (ii) reduce the minimum purchase price of a
Common Share subject to an option or (iii) extend the term of the 1995 Plan.
 
                                       32
<PAGE>   36
 
     Non-qualified stock options.  On August 15, 1995, the Committee granted
243,500 non-qualified options to certain officers of the Company and other
eligible persons, subject to approval of the 1995 Plan by the Company's
shareholders. See "Security Ownership of Certain Beneficial Owners and
Management." Each such option had an initial exercise price of $1.625 per Common
Share, which was the closing price of the Common Shares on the AMEX on the date
of grant, and vested immediately. The exercise price of all non-qualified stock
options must be no less than 25% of the fair market value of the Common Shares
on the date of the grant. Non-qualified options to purchase 4,000 Common Shares
are also granted automatically to non-employee directors (up to an aggregate of
12,000 options granted to each non-employee director under any plan of the
Company) on the date of each annual meeting of shareholders of the Company and,
on the date a person first becomes a non-employee director, such non-employee
director will be granted a number of options pro-rated for the period of time
until the next annual meeting of shareholders. Such options will be fully
exercisable one year after their date of grant with special provisions for death
and termination for disability and will expire ten years after the date of
grant.
 
     At its meeting on August 15, 1995, the Committee amended the terms of
substantially all options outstanding under the Company's 1984 Option Plan
(covering an aggregate of approximately 165,000 Common Shares) to reduce the
initial exercise price to $1.625 per Common Share, which was the closing price
of Common Shares on the AMEX on such date.
 
     In the event of certain change of control events or the approval by
shareholders of a reorganization, merger or consolidation (unless the Company's
shareholders receive 60% or more of the stock of the surviving company) or the
approval by shareholders of a liquidation, dissolution or sale of all or
substantially all of the Company's assets, all awards will become fully vested
and be "cashed-out" by the Company except, in the case of a merger or similar
transaction in which the shareholders receive publicly traded common stock, all
outstanding options will become exercisable in full, and each option will
represent a right to acquire the appropriate number of shares of common stock
received in the merger or similar transaction. Special provisions regarding
exercise exist in the event of death or termination for disability.
 
     Incentive Stock Options.  No incentive stock option will be exercisable
more than ten years after its date of grant, unless the recipient of the
incentive stock option owns greater than ten percent of the voting power of all
shares of capital stock of the Company (a "ten percent holder"), in which case
the option must be exercised within five years after its date of grant. The
option exercise price of an incentive stock option will not be less than the
fair market value of the Common Shares on the date of grant of such option,
unless the recipient of the incentive stock option is a ten percent holder, in
which case the option exercise price will be 110% of fair market value. Special
provisions regarding exercise exist in the event of death or termination for
disability.

    approval of the 1995 Plan, at an exercise price equal to $1.625, which was
    the closing price of the Common Shares on the AMEX on such date.
 
(2) Comprises four individuals who were granted options on August 15, 1995,
    subject to shareholder approval of the 1995 Plan, at an exercise price equal

(3) Comprises two individuals who were granted options on August 15, 1995,
    subject to shareholder approval of the 1995 Plan, at an exercise price equal
    to $1.625, which was the closing price of the Common Shares on the AMEX on
    such date.
 
(4) The option exercise price per share would be the closing sale price of the
    Common Shares on the AMEX on the date of grant. On October 6, 1995, the
    closing sale price of Common Shares on the AMEX was $1.625 per share. Each
    option will be fully exercisable one year after the date of grant and will
    expire ten years after the date of grant.
 
(5) Dollar value of options granted is calculated as the number of Common Shares
    underlying the options multiplied by the closing sale price of the Common
    Shares on the AMEX on the date of the grant. The taxable benefit received by
    each grantee upon exercise of the options will consist of any increase in
    the price of the Common Shares on the AMEX on the date of exercise from the
    closing price on the date of grant.
 
     In addition, the Board of Directors and the Company's shareholders have
approved the terms of a NonQualified Stock Option Agreement between the Company
and Dr. Bates. Pursuant to this Agreement, Dr. Bates may purchase, at any time
prior to August 15, 2005, up to 1,495,000 Common Shares at an initial exercise
price of $0.01 per share.
 
COMPENSATION OF DIRECTORS
 
     During 1994, non-employee directors were scheduled to receive an annual
retainer fee of $5,000 each. The non-employee directors agreed to defer payment
of the retainer fee during 1994 to assist the Company
 
                                       34
<PAGE>   38
 
with its cash flow. The 1994 retainer fees were paid in February 1995.
Non-employee directors also were entitled to receive $1,000 for attendance in
person at each regular and special meeting of the Board of Directors. In
addition, non-employee directors who were members of a committee of the Board of
Directors were entitled to receive $200 for attendance in person at each
committee meeting. Non-employee directors are not entitled to any fee for Board
of Directors or committee meetings held by conference telephone at which they
are not present in person. Of the four Board meetings held during 1994, one was
a regular meeting which directors attended in person, and three were special
meetings which were held by conference telephone. Non-employee directors also
received reimbursement of expenses incurred in attending meetings. No payment is
made for attendance at meetings by any director who is an employee of the
Company. The director compensation schedule for 1995 will not change from the
1994 schedule.
 
EMPLOYMENT AGREEMENTS
 
     In 1984, the Company entered into employment agreements with Ernest A.
Bates, M.D. (the Company's Chairman and Chief Executive Officer) and James R.
Brock (then the Company's Vice President -- Marketing) each of which was
automatically extended for successive one-year periods through January 1994 when
such agreements terminated in accordance with their terms. Each of the
agreements provided that, in the event of a change in control or sale of all or
substantially all of the assets of the Company, the employment agreements would
not terminate and the surviving, resulting or acquiring corporation would be
bound by the terms of the agreements. Each of these employment agreements
provided for salary increases to be determined by the Board of Directors and
certain other benefits.
 
BOARD OF DIRECTORS AND STOCK OPTION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     This Report of the Board of Directors and Stock Option Committee describes
the Company's method of compensating its executive officers, and describes the
basis on which 1994 compensation was paid to such executive officers, including
those named in the Summary Compensation Table.
 
     The Board of Directors determined that compensation paid in 1994 by the
Company to its Chief Executive Officer and other executive officers would be
based on policies in effect in recent prior years. As a result, it was
unnecessary for the Compensation Committee to meet, and it did not meet, during
1994.
 
     The Company's compensation program seeks to establish compensation that is
competitive in both the healthcare industry and among entrepreneurial,
growth-oriented companies in order to attract and retain high quality employees.
Compensation is linked to each employee's level of responsibility and personal
achievements with respect to operational and financial goals established by the
Chief Executive Officer and the Board of Directors. Depending on the individual
officer's area of responsibility, such goals may include new business and
revenue acquisition, operating expense reduction and control, operating
efficiencies, etc. In addition, the compensation system seeks to develop and
encourage employee ownership of the Company's stock through stock options.
 
     The primary component of executive compensation for the Company is base
salary, except in the case of the Senior Vice President -- Sales and Marketing
where sales commissions are a substantial component of compensation and are
included under "salary" in the Summary Compensation Table. Discretionary bonuses
may be paid, based on a formula, if financial and other results of the
individual executive's area of responsibility meet or exceed financial and
operational targets established at the beginning of the fiscal year. No bonuses
have been paid by the Company during the last three fiscal years, except in the
case of bonuses paid pursuant to pre-established formulae based on goals and
targets of a specific business area.
 
     Base salary was established for the Chief Executive Officer and other
executive officers with the assistance of an outside consulting firm in 1991.
Such compensation was designed to fall in the mid-range for the relevant
executive position or compensation paid by a group of entrepreneurial,
growth-oriented companies believed by the Company to be comparable in their
stage of development and business condition, based on information provided by
the independent compensation consulting organization. The companies surveyed
were not identical to those reflected in the performance graph set forth in this
Registration Statement. The compensation of most of the Company's senior
executives, including the Chief Executive Officer, was reduced
 
                                       35
<PAGE>   39
 
by up to 10% during the period from June 1991 through March 1992. Such executive
officers were compensated throughout 1993 at the level in effect prior to the
reductions. Any other increases in base compensation during the past three
fiscal years have been made only to reflect the increased responsibilities of
the particular executive officer. The compensation of certain of the Company's
executive officers again was reduced, beginning in February 1994, by 5%.
 
     In addition to base compensation, the Company has used grants of stock
options to retain senior executives (other than the Chief Executive Officer) and
to motivate them to improve long-term stock market performance. No new options
were granted during 1994. The number of options granted in the past was
determined by reference to the level of responsibility of the particular
executive in the Company and such executive's proposed role in the Company's
future operations. On August 15, 1995, the Board of Directors approved the 1995
Stock Option Plan and issued stock options to key employees and directors,
subject to shareholder approval. See "1995 Stock Option Plan."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION; CERTAIN
RELATIONSHIPS AND RELATED TRANSACTIONS
 
     On April 6, 1994, the Company entered into settlement agreements with each
of Elekta Instruments, Inc. ("Elekta"), the manufacturer of the Gamma Knife, and
NME Hospitals, Inc., d/b/a USC University Hospital ("USC Hospital"), the lessor
of a Gamma Knife, to resolve disputes arising out of the Company's inability to
make a required progress payment under the agreement to purchase such Gamma
Knife. The settlement agreements required that the Company terminate its
original agreement to purchase the Gamma Knife from Elekta and to lease the
Gamma Knife to USC Hospital. Further conditions to execution of the settlement
agreements included that Dr. Bates, the Company's Chairman and Chief Executive
Officer, enter into a purchase agreement and lease agreement with Elekta and USC
Hospital, respectively, substantially identical to the respective terminated
agreements.
 
     Pursuant to the new purchase agreement, Dr. Bates was entitled to purchase
the Gamma Knife from Elekta for an aggregate purchase price of $2,900,000 plus
sales tax. Dr. Bates obtained financing for the Gamma Knife purchase from an
unaffiliated third party. Dr. Bates' lender has financed the total purchase
price, less $290,000 advanced by the Company, pursuant to an interest bearing
installment note and security agreement. The Company has advanced $290,000 of
the purchase price, to be repaid by Dr. Bates over the term of the new lease
agreement, pursuant to a promissory note bearing interest at 6% per annum and
repayable over 60 months.
 
     The Company and Dr. Bates, have entered into an option agreement entitling
the Company to purchase the Gamma Knife from Dr. Bates for an amount equal to
the remaining debt obligations associated with the Gamma Knife plus costs and
losses, if any, incurred by the Chief Executive Officer, when the Company is
able to obtain financing for this purchase. It is the Company's intent to
exercise the option to purchase the Gamma Knife from Dr. Bates as soon as the
Company is able to obtain the required funds.
 
     On October 6, 1995 the Company entered into the Option Agreement with its
Chairman and Chief Executive Officer. Under the Option Agreement, Dr. Bates was
granted a ten-year option to purchase 1,495,000 Common Shares for an initial
exercise price of $0.01 per share. In addition, on May 17, 1995, as part of the
Notes Repurchase, the Company issued 184,000 Common Shares to Dr. Bates in
partial consideration of his personal guarantee of $6,500,000 of indebtedness of
the Company.

     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 during 1994 and 1995. 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.

     Because the Selling Securityholders may sell all or a part of their Common
Shares and Warrants, no estimate can be given as to the number of Common Shares
or Warrants to be held by any Selling Securityholders upon termination of the
offering. The Common Shares owned by the Selling Securityholders represent
approximately 28% of the issued and outstanding Common Shares and the Common
Shares underlying the Warrants represent approximately 11% of the issued and
outstanding Common Shares plus those Common Shares underlying the Warrants.

                           DESCRIPTION OF SECURITIES
 
COMMON SHARES
 
     The authorized capital stock of the Company consists of 10,000,000 Common
Shares, no par value. At October 6, 1995, 4,244,401 shares were issued and
outstanding and were held of record by 425 persons. The Company estimates there
were approximately 1700 beneficial holders of its Common Shares as of October 6,
1995. The Common Shares of the Company are listed on the American Stock Exchange
and The Pacific Stock Exchange under the symbol "AMS." The Company's Board of
Directors has authorized completion of listing applications for additional
Common Shares with the AMEX and PSE with respect to the Securities. See "Market
Price on and Dividends on the Registrant's Common Shares."
 
     Each Common Share has the same rights, privileges and preferences as every
other share and will share equally in the Company's net assets upon liquidation
or dissolution. The Common Shares have no conversion or redemption rights or
sinking fund provisions. All Common Shares outstanding are, and all Common
Shares issued upon exercise of the Warrants will be, validly issued, fully paid
and non-assessable. The Common Shares have no preemptive rights. Shareholders
are entitled to one vote for each share owned on all matters submitted to the
shareholders and have the right, subject to certain conditions, to elect to
cumulate their votes in the election of directors. Shareholders are entitled to
receive such dividends as may be declared by the Board of Directors out of funds
legally available therefor. The Company did not pay dividends in 1993 or 1994
and does not intend to pay dividends in the near future. See "Market Price on
and Dividends on the Registrant's Common Shares" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" for a description
of financing agreements that prohibit or restrict the declaration of dividends
on the Common Shares.
 
     The transfer agent and registrar for the Common Shares is American Stock
Transfer & Trust Company, New York, New York.
 
WARRANTS
 
     GE Warrants.  The GE Warrants entitle the registered holder thereof to
acquire up to 225,000 Common Shares at an initial exercise price of $0.01 per
share, of which 97,853 Common Shares may be purchased to and including March 31,
1996 and 127,147 Common Shares may be purchased to and including September 30,
1996. The GE Warrants were issued in certificated form. The GE Warrants may be
exercised by surrendering the warrant certificate evidencing such Warrants, a
written election to exercise the GE Warrant specifying the number of Common
Shares to be purchased and the payment of the exercise price. Payment of the
exercise price may be made by check payable to the Company. Upon surrender of
the warrant certificate and payment of the purchase price, the Company will
deliver or cause to be delivered stock certificates representing the number of
whole Common Shares to which such holder is entitled. If less than all of the GE
Warrants evidenced by a warrant certificate are to be exercised, a new warrant
certificate will be issued for the remaining number of GE Warrants. No
fractional Common Shares will be issued upon exercise of the GE Warrants. A
fractional share otherwise issuable will be rounded up to the nearest whole
share.
 
     The number of Common Shares purchasable upon the exercise of the GE
Warrants and the exercise price are subject to adjustment in certain events (and
subject to certain limitations set forth in the warrant certificate) including:
(i) the payment by the Company of a dividend or the making of a distribution on
its Common Shares in additional Common Shares or in securities convertible into
Common Shares other than convertible indebtedness or convertible preferred
stock, (ii) subdivisions and combinations of the Common Shares, and (iii)
reclassifications of the Common Shares.
 
     Until exercise of the GE Warrant and the purchase of Common Shares, the
holder of the GE Warrants has no right to vote on matters submitted to the
shareholders of the Company and has no right to receive dividends. Until such
time, the holder of the GE Warrants is not entitled to share in the net assets
of the Company in the event of liquidation, dissolution or the winding up of the
Company's affairs.
 
                                       42
<PAGE>   46
 
     Noteholder Warrants.  The Noteholder Warrants entitle the registered
holders thereof to acquire up to 314,000 Common Shares at an initial exercise
price of $0.75 per share up to and including May 17, 2002. The Noteholder
Warrants were issued in certificated form. The Noteholder Warrants may be
exercised by surrendering the warrant certificate evidencing such warrants, a
written election to exercise the Noteholder Warrant specifying the number of
Common Shares to be purchased and the payment of the exercise price. Payment of
the exercise price may be made at the holder's option (a) in cash, (b) by
certified or official bank check payable to order of the Company, or (c) by the
Company withholding that number of shares of Common Shares with a value as of
the date of exercise equal to the aggregate exercise price. Upon surrender of
the warrant certificate and the purchase price, the Company will deliver or
cause to be delivered stock certificates representing the number of Common
Shares designated to be exercised, less the number of Common Shares withheld by
the Company as payment therefor, if applicable. If less than all of the
Noteholder Warrants evidenced by a warrant certificate are to be exercised, a
new warrant certificate will be issued for the remaining number of Noteholder
Warrants. No fractional Common Shares will be issued upon exercise of the
Noteholder Warrants. The Company shall pay to the holder of the Noteholder
Warrant an amount in cash equal to the same fraction of the current value per
share on the date of the exercise.
 
     The number of Common Shares purchasable upon the exercise of the Noteholder
Warrants and the exercise price are subject to adjustment in certain events (and
subject to certain limitations set forth in the warrant certificate) including:
(i) the payment of a dividend on its Common Shares in additional shares of
Common Shares, (ii) the payment of a dividend or other distribution on its
Common Shares or other issuance to all holders of its Common Shares of rights or
warrants entitling them to subscribe for Common Shares at a price per share less
than the current market price on the record date of such dividend, distribution
or issuance, (iii) subdivisions, combinations and reclassifications of the
Common Shares, (iv) subject to an election to receive such dividend or
distribution, the distribution to all holders of Common Shares of evidences of
indebtedness, shares of capital stock, cash or assets (including securities, but
excluding any dividend or distribution referred to in clauses (i) or (ii) above
for which an adjustment is made), and (v) the issuance or sale of shares of
Common Shares by the Company for consideration per share less than the current
market price.
 
     No adjustment in the number of Common Shares purchasable and the exercise
price will be required unless such adjustment would require an increase or
decrease of at least 1% in the exercise price; provided, however, that any
adjustment that is not made will be carried forward and taken into account in
any subsequent adjustment.
 
     In case of certain consolidations, mergers or capital reorganizations or
reclassifications of the Company, each holder of a Noteholder Warrant shall be
entitled to receive, in lieu of the Common Shares of the Company, the kind and
amount of securities, cash or other property to which such holder would have
been entitled upon such consummation if such holder had exercised the Noteholder
Warrant in full immediately prior thereto.
 
     The holders of the Noteholder Warrants have no right to vote on matters
submitted to the shareholders of the Company. Except as set forth in the warrant
certificate with respect to the right to elect to receive certain distributions,
the holders of the Noteholder Warrants have no right to receive dividends. The
holders of the Noteholder Warrants are not entitled to share in the net assets
of the Company in the event of liquidation, dissolution or the winding up of the
Company's affairs.
 
                              PLAN OF DISTRIBUTION
 
     The Selling Securityholders may sell the Securities: (i) in an underwritten
offering or offerings, (ii) through brokers and dealers, (iii) "at the market"
to or through a market maker or into an existing trading market, on an exchange
or otherwise, for such shares, (iv) in other ways not involving market makers or
established trading markets, including direct sales to purchasers and (v) to the
extent not prohibited by applicable securities law, in ways other than pursuant
to the distribution plan presented in the Prospectus. Pursuant to the terms of
the Registration Rights Agreement, the Company has agreed to maintain the
 
                                       43
<PAGE>   47
 
effectiveness of the registration statement for a period of 36 months or until
all of the Securities have been sold, if earlier.
 
     The distribution of Securities may be effected from time to time in one or
more underwritten transactions at a fixed price or prices, which may be changed,
or at market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices. Any such underwritten offering
may be on a "best efforts" or a "firm commitment" basis.
 
     In connection with any such underwritten offering, underwriters or agents
may receive compensation from the Selling Securityholders for whom they may act
as agents in the form of discounts, concessions or commissions. Underwriters may
sell Securities to or through dealers, and such dealers may receive compensation
in the form of discounts, concessions or commissions from the underwriters
and/or commissions from the purchasers for whom they may act as agents.
 
     At any time a particular offer of Securities is made, if required, a
Prospectus Supplement will be distributed that will set forth the names of the
Selling Securityholder(s) offering such Securities, the aggregate amount of such
Securities being offered and the terms of the offering, including the name or
names of any underwriters, dealers or agents, any discounts, commissions and
other items constituting compensation from the Selling Securityholders and any
discounts, commissions or concessions allowed or reallowed or paid to dealers.
Such Prospectus Supplement and, if necessary, a post-effective amendment to the
Registration statement of which this Prospectus is a part will be filed with the
Commission to reflect the disclosure of additional information with respect to
the distribution of such Securities.
 
     The Selling Securityholders and any underwriters, dealers or agents that
participate in the distribution of Securities may be deemed to be underwriters,
and any profit on the sale of Securities by the Selling Securityholders and any
discounts, commissions or concessions received by any such underwriters, dealers
or agents might be deemed to be underwriting discounts and commissions under the
Act.
 
     Under an agreement that may be entered into by the Company, underwriters,
dealers, and agents who participate in the distribution of Securities may be
entitled to indemnification by the Company against certain liabilities,
including liabilities under the Act, or to contribution with respect to payments
which such underwriters, dealers or agents may be required to make in respect
thereof.
 
     The sale of the Securities by the Selling Securityholders may also be
effected from time to time by Selling Securities directly to purchasers or to or
through certain broker-dealers. In connection with any such sale, any such
broker-dealer may act as agent for the Selling Securityholders or may purchase
from the Selling Securityholders all or a portion of the Securities as principal
and thereafter may resell any Securities so purchased. Sales by any such
broker-dealer, acting as agent or as principal, may be made pursuant to any of
the methods described below. Such sales may be made on the AMEX or PSE or other
exchanges on which the Common Shares are then traded, in the over-the-counter
market, in negotiated transactions or otherwise at prices and at terms then
prevailing or at prices related to the then-current market prices or at prices
otherwise negotiated.
 
     The Securities may also be sold in one or more of the following
transactions: (a) block transactions (which may involve crosses) in which a
broker-dealer may sell all or a portion of such shares as agent but may position
and resell all or a portion of the block as principal to facilitate the
transaction; (b) purchases by any such broker-dealer as principal and resale by
such broker-dealer for its own account pursuant to this Prospectus which is part
of the Registration Statement; (c) a special offering, an exchange distribution
or a secondary distribution in accordance with applicable stock exchange rules;
and (d) ordinary brokerage transactions and transactions in which any such
broker-dealer solicits purchasers. In effecting sales, broker-dealers engaged by
the Selling Securityholders may arrange for other broker-dealers to participate.
Broker-dealers will receive commissions or other compensation from the Selling
Securityholders in amounts to be negotiated immediately prior to the sale that
will not exceed those customary in the types of transaction involved.
Broker-dealers may also receive compensation from purchasers of the shares which
is not expected to exceed that customary in the types of transactions involved.

                         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, 1994 and 1993, 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, 1994. 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, 1994 and 1993, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1994, 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 substantial operating losses in
1994, 1993 and 1992 and has a significant working capital deficiency and a net
capital deficiency at December 31, 1994. 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. 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1994
                   (INFORMATION AS OF AND FOR THE SIX MONTHS
                       ENDED JUNE 30, 1995 IS UNAUDITED)
 
1. BUSINESS AND BASIS OF PRESENTATION
 
   
     American Shared Hospital Services (the "Company") provides multimodality
diagnostic and respiratory therapy services to hospitals and other medical care
providers. The consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries, CuraCare, Inc. ("CuraCare"), MMRI,
Inc., European Shared Medical Services Ltd., American Shared Radiosurgery
Services, African American Church Health & Economic Services, Inc., and ACHES
Insurance Services, Inc. All significant intercompany accounts and transactions
have been eliminated. The Company accounts for its investment in partnerships
using the equity method.
    
 
     The Company incurred net losses of $5,175,000, $15,644,000 and $9,515,000
in 1994, 1993 and 1992, respectively. At December 31, 1994, the Company has a
working capital deficiency of $33,369,000 (including $18,467,000 in senior
subordinated notes in default and classified as current liabilities) and a net
capital deficiency of $22,341,000. This condition raises 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.
 
     The financial information as of June 30, 1995 and for the six months ended
June 30, 1995 is unaudited, but includes all adjustments (consisting of only
normal recurring adjustments) that the Company considers necessary for a fair
presentation of the financial position at such date and the operating results
and cash flows for those periods. Operating results for the six months ended
June 30, 1995 are not necessarily indicative of the results that may be expected
for the entire year ending December 31, 1995.
 
2. ACCOUNTING POLICIES
 
  Revenues and Accounts Receivable
 
     Revenue is recognized on a fee-for-service 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's revenues from its
foreign operations comprised approximately 1% of total 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.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of three months or less at the date of purchase to be cash
equivalents.
 
  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).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
                               DECEMBER 31, 1994
                   (INFORMATION AS OF AND FOR THE SIX MONTHS
                       ENDED JUNE 30, 1995 IS UNAUDITED)
 
  Property and Equipment
 
     Property and equipment is stated at cost, or estimated net recoverable
value if less, and is depreciated by the straightline method over the estimated
useful lives of the assets which are generally as follows:
 
<TABLE>
            <S>                                                      <C>
            Building and improvements..............................  25-40 years
            Medical and transportation equipment...................  2-10 years
</TABLE>
 
     Capitalized leased equipment consists primarily of fixed and mobile
Magnetic Resonance Imaging ("MRI") units, which include scanners and mobile
vans. Capitalized leased equipment is amortized over the term of lease, which
range from 24 to 60 months, or the estimated useful life of the equipment if a
bargain purchase option exists (eight years). Leasehold improvements are
amortized over the shorter of the lease terms or the estimated useful lives.
 
     During 1993 and 1992, the Company experienced a decline in the market
acceptance of certain of its less advanced MRI and CT scanning equipment.
Accordingly, the Company reduced the carrying value of this equipment to the
Company's estimate of the future revenue generating capacities of the equipment.
These write-downs resulted in a charge to operations of $443,000 and $3,454,000
in 1993 and 1992, respectively. (See Unaudited Note 16 for further discussion.)
 
     During the six months ended June 30, 1995 and years ended December 31,
1994, 1993 and 1992, the Company incurred interest costs of $3,274,000,
$7,423,000, $6,828,000 and $7,569,000, respectively. The Company capitalized
interest related to construction in progress of $0, $0, $76,000 and $49,000 for
the six months ended June 30, 1995 and the years ended December 31, 1994, 1993,
and 1992, respectively.
 
  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 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.
 
  Per Share Amounts
 
     Per share information has been computed based on the weighted average
number of common shares and dilutive common share equivalents outstanding.
 
  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.
 
3. WRITE-DOWN OF INTANGIBLE ASSETS
 
     During 1993, the Company's management continued to evaluate the
realizability of intangible assets recorded in connection with its acquisition
of CuraCare in 1987, which subsidiary conducts substantially all of the
Company's non-MRI operations, including CT scanning, respiratory therapy,
ultrasound and nuclear

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
                               DECEMBER 31, 1994
                   (INFORMATION AS OF AND FOR THE SIX MONTHS
                       ENDED JUNE 30, 1995 IS UNAUDITED)
 
medicine. Revenues and operating profits from CuraCare, have continued to
decline significantly over the past few years despite several strategic plans
implemented by management. In the fourth quarter of 1993, management continued
to evaluate its non-MRI operations and determined that significant revenue
growth was unlikely and reduced its operations management and sales force
accordingly.
 
     These conditions helped to contribute to higher than expected losses in
1992 and 1993 and an accumulated deficit at December 31, 1993, before the
write-off of goodwill. The Company has determined, based on its methodology of
evaluating the recoverability of goodwill, that the forecasted results of
operations for non-MRI operations (which were based on historic financial trends
and current market conditions) did not support the future amortization of the
recorded goodwill balance of $5,308,000 at December 31, 1993, for these
modalities.
 
     The methodology employed to assess the recoverability of the Company's
goodwill was to forecast results of operations, including interest expense,
forward five years. The Company then evaluated the recoverability of goodwill on
the basis of these forecasts of future operations. In formulating the financial
forecasts, the Company considered the near-term, as well as the longer-term
business outlook. These near-term forecasts took into consideration recent
historical financial results and current market conditions, as well as
foreseeable opportunities for future growth. For the longer-term, the Company
also considered the possible emergence of new trends and their potential impact
upon each of the modalities.
 
     Based on such forecasts, the cumulative results of operations for non-MRI
operations were insufficient to recover any portion of the respective goodwill
balances. Accordingly, the Company wrote off its remaining goodwill balances for
these operations of $5,308,000 in the fourth quarter of 1993.
 
4. INVESTMENT IN PARTNERSHIPS
 
     The Company has entered into partnerships with health care providers for
the acquisition and operation of CT scanners, and records its investment and its
share of partnership earnings under the equity method. The summarized combined
financial position and results of operations of the partnerships are as follows:

6. SENIOR SUBORDINATED NOTES
 
     In 1988, the Company completed a concurrent public common stock and debt
offering consisting of $30,000,000 of senior subordinated exchangeable reset
notes (the "Notes") due in 1996. The Notes bore interest at an initial rate of
14% per annum payable semiannually commencing April 15, 1989. On October 15,
1989, the interest rate on the Notes not previously exchanged, as described
below, was reset to 16.5%.
 
     Prior to the October 15, 1989 reset date, $2,140,000 of Notes were
exchanged into 14.75% senior subordinated notes due 1996. Except for the
interest rate, optional and mandatory redemption provisions of the Notes and the
fact that the 14.75% Notes were not exchangeable, the terms of the 14.75% Notes
are substantially the same as the terms of the Notes. The Company may redeem all
or part of the Notes for 100% of the principal amount, together with accrued and
unpaid interest to the redemption date.
 
     The Company was required to make mandatory sinking fund payments of
$4,500,000 annually commencing October 15, 1994, reduced by the principal amount
of notes previously repurchased and canceled. These payments are calculated to
retire 30% of the issue prior to maturity. Previously repurchased and canceled
notes were adequate to satisfy mandatory sinking fund payments.
 
     Under the terms of the loan indenture, the Company is required to maintain
consolidated net worth (shareholders' equity as defined) of at least $7,000,000.
In the event consolidated net worth is below $7,000,000 at the end of any two
consecutive fiscal quarters, the Company is required to make an offer within 65
days to repurchase 25% ($7,500,000) of the original principal amount of the
Notes at face value plus accrued interest. The debt agreement limits the
Company's ability to adopt a plan of sale or liquidation and to incur certain
types of additional indebtedness subject to meeting certain earnings to fixed
charge ratios, as defined. The debt agreement also limits the amount of
dividends the Company can declare on capital stock to the sum of (1) 50% of
consolidated net income, or 100% of net loss, since June 30, 1988; (2) 50% of
the net proceeds from the sale of capital stock, or debt that has subsequently
been converted to capital stock; (3) $2,000,000.

  Foothill Loan
 
     In March 1991, the Company entered into a loan agreement (as amended),
which initially expired in March 1993 and was extended for periodic terms
through March 1994, under which it could generally borrow up to 66% of eligible
accounts receivable, reduced to 50% if total borrowings equal or exceed
$4,000,000, up to a maximum of $5,000,000. On March 30, 1994, the agreement was
modified to extend its term through February 28, 1995. Proceeds from loans under
the agreement can only be used to repurchase the Company's senior subordinated
notes. Borrowings under the agreement bear interest at the prime rate plus 4%
(12.5% at December 31, 1994), payable monthly. 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 security interest in all accounts
receivable and certain land and buildings. The loan agreement prohibits the
Company from acquiring, merging or consolidating with any other business
organization, from making any change in its financial structure and from
prepaying existing indebtedness, without the consent of the lender. A former
Director of the Company is the President and Co-Chief Executive of the lender.
 
     On December 31, 1994, with the proceeds from the sale of certain of the
Company's respiratory therapy contracts (see Note 12), the Company deposited
approximately $2,900,000 cash as collateral with the lender. On February 28,
1995 the loan agreement was terminated.
 
  Restructuring Notes
 
     On December 30,1994 the Company converted various service and other
payments that were due and unpaid into a $2,000,000 promissory note with its
primary provider of medical equipment. The note is dated January 1, 1995 and was
issued by the Company in conjunction with the lease restructuring (see Note 11).
The note matures in February 2002 and bears interest at an annual rate of 4%
payable in arrears. Monthly payments of interest only are due for the first
eleven months through November 1995. Thereafter, the principal balance of the
note will amortize in 75 equal monthly installments until maturity. The note is
secured by a second priority lien on the accounts receivable of the Company and
a first priority lien on certain medical equipment.
 
     The Company also 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.
 
     The restructuring notes limit the Company's ability to merge with any other
entity, to create subsidiaries, to pay cash dividends, to repurchase stock for
cash, or to change the status of the equipment acting as collateral in such a
way as to impair its value.

     The decrease in the valuation allowance from December 31, 1994 to June 30,
1995 and from December 31, 1993 to December 31, 1994 of $2,264,000 and
$4,538,000, respectively was due primarily to a decline in the net operating
loss carryforward for 1995 and to an increase in total deferred tax assets
related to fixed assets for 1994.

     At December 31, 1994, the Company had a net operating loss carryforward for
federal income tax return purposes of approximately $30,000,000 which expires
between 1999 and 2008. This carryforward is subject, in part, to separate return
limitations. The Company's ability to utilize the net operating loss
carryforward may be limited in the event of a 50% or more ownership change
within any three-year period. Approximately $22,600,000 (unaudited) of the net
operating loss carryforward was used to offset the gain on early extinguishment
of the senior subordinated notes in May 1995.
    
 
9. STOCKHOLDERS' EQUITY
 
  Stock Options
 
     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 may be designated either as
"incentive stock options" (as defined in the Internal Revenue Code, as amended)
or as nonqualified options. Under the Plan, the exercise price must be at least
100% of the fair market value of the Company's common stock as of the date of
grant. Options granted generally become exercisable at the rate of 20% per year,
on a cumulative basis, beginning 11 months after the date of the grant. Options
granted pursuant to the Plan generally were good for 10 years from the date of
grant, subject to earlier expiration in certain cases, such as termination of
the grantee's employment.

11. LEASES
 
     On December 30, 1994 (effective as of November 1, 1994 for most capital
leases and January 1, 1994 for operating leases) the Company and its major
provider of medical equipment entered into a restructuring of the obligations of
the Company under its capital leases and operating leases.
 
  Modification of Leases
 
     Substantially all equipment financed by the Company under capital leases
was restructured and after restructuring continues to meet the criteria of and
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 now meet the
criteria for capitalization, and are accounted for as capital leases in the
accompanying financial statements. Under all the modified leases the Company
will be entitled to purchase the equipment at its fair market value, or to
extend the relevant lease, at the end of the lease term.
 
  Capital Leases
 
     The Company leases MRI units and other equipment under capital leases
having an aggregate net book value of $20,584,000 at June 30, 1995 and
$28,177,000 at December 31, 1994. Amortization of assets recorded under capital
leases is included with depreciation expense.
 
     Future minimum lease payments, together with the present value of the net
minimum lease payments under capital leases are summarized as follows:

12. SALE OF RESPIRATORY THERAPY CONTRACTS
 
     The Company sold eight of fourteen respiratory therapy contracts to an
unrelated third party on December 31, 1994 for approximately $4,000,000 in cash.
As a result of the sale, the Company wrote off $180,000 in assets relating to
the contracts. In addition, the purchaser agreed to assume $300,000 in lease
obligations related to the assets. The Company recognized a gain on this
transaction of $3,199,000. Revenues generated under these contracts was
approximately $5,300,000 in 1994. A net loss in 1994 of $400,000 was recognized
on these contracts on a fully costed basis. The sale of the contracts
constitutes a sale of a portion of a product line in which the Company is
reducing its emphasis.
 
13. NOTE RECEIVABLE FROM OFFICER
 
     At December 31, 1994, the Company has advanced $290,000 to the Chief
Executive Officer who executed a promissory note payable to the Company. The
note bears interest at 6% and is payable in 60 monthly fully amortizing payments
beginning in January 1995. Interest income recognized during the year was
$12,000 and has been added to the note receivable balance.
 
14. COMMITMENTS AND CONTINGENCIES
 
     In January 1993, the Company entered into a commitment to purchase a Gamma
Knife for $2,900,000 and lease the Gamma Knife to a hospital. During 1993,
$1,090,000 was advanced to the equipment manufacturer ("the Manufacturer")
including $800,000 advanced by a third party lessor and guaranteed by the Chief
Executive Officer of the Company. The Company was unable to pay or finance
scheduled progress

payments and had been informed by the manufacturer that the Company was in
default under the terms of the purchase agreement and that such agreement was
terminated.
 
     On April 6, 1994, the Company's agreements to purchase a Gamma Knife from
an equipment manufacturer and lease the Gamma Knife to a hospital were
terminated. As a settlement, the Company paid approximately $130,000 in interest
and costs to the parties and the Company's Chief Executive Officer agreed to
enter into purchase and lease obligations substantially identical to those
previously entered into by the Company. The Manufacturer has agreed to sell the
Gamma Knife to, and the hospital agreed to lease the Gamma Knife from, the
Company's Chief Executive Officer. Of the $1,090,000 in deposits previously paid
to the Manufacturer, $800,000 was returned to the third party lessor and
$290,000 previously paid by the Company was advanced by the Company to the Chief
Executive Officer who executed a promissory note payable (Note 13).
Concurrently, the third party lessor agreed to fund the remaining $2,610,000
purchase price of the Gamma Knife on behalf of the Chief Executive Officer and
the Company received an option to purchase the Gamma Knife from the Chief
Executive Officer for an amount equal to the remaining debt obligation
associated with the Gamma Knife plus costs and operating losses, if any, on the
Gamma Knife if and when the Company is able to obtain financing for the
purchase.
 
15. SUBSEQUENT EVENTS -- DEBT RESTRUCTURING
 
     Subsequent to year-end, on May 12, 1995, the Company entered into a revised
debt restructuring agreement with four holders of approximately 96% of its
Senior Subordinated Notes. On May 17, 1995, these Senior Subordinated
Noteholders received approximately $3,900,000 in cash, plus 819,000 shares of
common stock (equal to approximately 20% of the Company's then fully diluted
outstanding shares), and warrants for an additional 216,000 shares of common
stock (equal to approximately 5% of the then fully diluted common shares). The
warrants are immediately exercisable at $0.75 per share. As part of the
restructuring, the debt covenants were amended to remove the restrictions on the
payment of dividends, to remove the maintenance of consolidated net worth
requirements, and to remove the limitations on entering into additional
indebtedness which thereby cured the events of default on the Senior
Subordinated Notes.
 
     Concurrent with the closing of the Notes repurchase, the Company obtained
three new credit facilities totaling $8 million. Proceeds from the new credit
facilities were used for the Notes repurchase, for reduction of other term debt,
for refinancing certain equipment, and for working capital.
 
     Simultaneous with the Notes repurchase, Ernest A. Bates, M.D. the Company's
Chairman and Chief Executive Officer, was issued an additional 184,000 shares of
the Company's common stock. The common shares were granted to Dr. Bates in
partial consideration for his personal guarantees of the new credit facilities
and for his continued employment with the Company.
 
     The remaining holders of the Company's Senior Subordinated Notes which was
not repurchased were paid their past due interest.
 
     As a result of the debt restructuring, the Company recognized an
extraordinary gain of $20,378,000 for the six months ended June 30, 1995.

Dr. Bates, the ex-Noteholders of the Senior Subordinated Notes were granted
374,000 additional common shares and 98,000 additional warrants to purchase

  Stock Option Plan
 
     On October 6, 1995, the shareholders approved the Company's 1995 Stock
Option Plan. Under the Plan, 330,000 shares of common stock have been reserved
for award to officers and other key employees, and to non-employee directors. On
August 15, 1995, the Stock Option Committee of the Board of Directors granted
243,500 options under the Plan, subject to shareholder approval. All such
options were immediately exercisable at an exercise price of $1.625 per share.
On October 6, 1995, options for an additional 12,000 shares were automatically
granted in accordance with terms of the Plan to three Directors. The options
were immediately exercisable at $1.625 per share.
 
  Adoption of FASB 121 -- Accounting for Long Lived Assets
 
     In connection with the 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 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 future forecasted operating results for certain
assets which were 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
provisions of FAS 121. An impairment loss of $4,425,000 was recorded in the
second quarter of 1995 based on the differences between the fair value
determined by third parties and the recorded values of certain assets. The
impairment loss is comprised of write-downs of equipment of $3,650,000
(primarily MRI, CT and nuclear medicine); goodwill of $600,000; and deferred
assets of $175,000.
 
  New Subsidiaries and Ventures
 
     GK FINANCING, LLC.
 
     On October 6, 1995, the Company through its wholly owned subsidiary
American Shared Radiosurgery Services (ASRS) and Elekta AB through its wholly
owned United States subsidiary GKV Investments, Inc. (GKV) reached an agreement
in principle to form GK Financing, LLC (GKF).
 
   
     ASRS intends to contribute its ownership of two existing Gamma Knife units
in return for approximately a 78% ownership interest in GKF. GKV is contributing
approximately $800,000 in cash for its 22% ownership interest. GKV has also
committed to making an initial loan to GKF of $1,300,000.
    
 
   
     GK Financing, LLC will provide alternative financing of Elekta Gamma Knife
units in the United States and in Brazil. GKF will be a preferred provider of
financing arrangements such as fee-for-service lease arrangements. GKF has
placed deposits totalling $1,000,000 for four (4) Gamma Knife Systems.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 204(10) of the California General Corporation Law ("GCL") permits
the inclusion in the articles of incorporation of a California corporation of a
provision eliminating or limiting the personal liability of a director for
monetary damages in an action brought by or in the right of the corporation for
breach of a director's duties to the corporation and its shareholders. The
foregoing provision is subject to certain qualifications set forth in the GCL
including, without limitation, that such provision may not limit or eliminate
liability of directors for (i) intentional misconduct, (ii) transactions from
which a director derived an improper personal benefit, (iii) reckless disregard
of the director's duties, and (iv) an unexcused pattern of inattention. The
Company's Articles of Incorporation, as amended, contains an article eliminating
the liability of the directors for monetary damages to the fullest extent
permissible under California law.
 
     Section 317 of the GCL permits the indemnification of officers, directors,
employees and agents of California corporations. Article Fifth, Section 2, of
the Company's Articles of Incorporation, as amended, provides that the
Registrant is authorized to provide indemnification to its agents in excess of
the indemnification otherwise permitted by Section 317 of the GCL.
 
     Article IX, Section 7, of the Bylaws of the Company contains the following
indemnification provision:
 
     Section 7. Indemnification of Corporate Agents; Purchase of Liability
Insurance.  (a) The Corporation shall, to the maximum extent permitted by the
General Corporation Law of the state of California, and as the same may from
time to time be amended, indemnify each of its agents against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with any proceeding to which such person was or is a party or is
threatened to be made a party arising by reason of the fact that such person is
or was an agent of the Corporation. For purposes of this Section 7, an "agent"
of the Corporation includes any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another foreign or
domestic corporation, partnership, joint venture, trust or other enterprise, or
was a director, officer, employee or agent of a foreign or domestic corporation
which was a predecessor corporation of the Corporation or of another enterprise
at the request of the such predecessor corporation; "proceeding" means any
threatened, pending or completed action or proceeding, whether civil, criminal,
administrative or investigative, and includes an action or proceeding by or in
the right of the Corporation to procure a judgment in its favor; and "expenses"
includes attorneys' fees and any expenses of establishing a right to
indemnification under this subdivision (a).
 
                                      II-1
<PAGE>   71
 
     (b) The Corporation shall, if and to the extent the Board of Directors so
determines by resolution, purchase and maintain insurance in an amount and on
behalf of such agents of the Corporation as the Board may specify in such
resolution against any liability asserted against or incurred by the agent in
such capacity or arising out of the agent's status as such whether or not the
Corporation would have the capacity to indemnify the agent against such
liability under the provisions of this Section 7.
 
     Each of the directors of the Corporation has entered into an
Indemnification Agreement with the Company pursuant to which the Company is,
subject to the limitations in the following sentence, obligated to indemnify the
directors to the fullest extent provided by law, notwithstanding such
indemnification not specifically being provided in the Company's Articles,
Bylaws or by statute. The Company is not obligated under the Indemnification
Agreement to indemnify directors for the following: acts or omission or
transactions from which a director may not be relieved from liability under
Section 204 of the California General Corporation Law, a proceeding or action
instituted by an appropriate bank regulatory agency, claims initiated by such
director except with respect to proceedings to enforce a right of
indemnification unless the Board has approved the initiation or bringing of such
suit, a proceeding instituted by a director to enforce the Indemnification
Agreement which is found by a court of competent jurisdiction to be not in good
faith or frivolous, insured claims or claims under Section 16(b) of the
Securities Exchange Act of 1934.

ITEM 17.  UNDERTAKINGS
 
     The undersigned hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (A) To include any prospectus required by Section 10(a)(3) of the
        Act;
 
             (B) To reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration
 
                                      II-4
<PAGE>   74
 
        Statement. Notwithstanding the foregoing, any increase or decrease in
        volume of securities offered (if the total dollar value of securities
        offered would not exceed that which was registered) and any deviation
        from the low or high and of the estimated maximum offering range may be
        reflected in the form of prospectus filed with the Commission pursuant
        to Rule 424(b) if, in the aggregate, the changes in volume and price
        represent no more than 20 percent change in the maximum offering price
        set forth in the "Calculation of Registration Fee" table in the
        effective Registration Statement;
 
             (C) To include any material information with respect to the plan of
        distribution not previously disclosed in the Registration Statement or
        any material change to such information in the Registration Statement.
 
          (2) That, for the purpose of determining any liability under the Act,
     each such post-effective amendment shall be deemed to be a new registration
     statement relating to the securities offered therein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the Securities being registered which remain unsold at the
     termination of the offering.
 
     b. Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Company pursuant
to the foregoing provisions, or otherwise, the registrant has been advised that
in the opinion of the Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
American Shared Hospital Services
 
     We have audited the consolidated financial statements of American Shared
Hospital Services as of December 31, 1994 and 1993, and for each of the three
years in the period ended December 31, 1994, and have issued our report thereon
dated March 24, 1995, except for Note 15, as to which the date is May 17, 1995
(included elsewhere in this Registration statement). Our audits also included
the financial statement schedule listed in Item 16(b) of this Registration
statement. This schedule is the responsibility of the Company's management. Our
responsibility is to express an opinion based on our audits.
 
   
     In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly in all material respects the information set forth
therein. The financial statement schedule does 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.

business office in the State of California.

        Section 2.  Change in Location or Number of Offices.  The Board of

        Section 1.  Place of Meetings.  Meetings of the shareholders shall be

<PAGE>   6
        Section 3.  Special Meetings.  (a) Special meetings of the shareholders
may be called by the Board of Directors, the Chairman of the Board and the
President or by the shareholders upon the request of the holders of shares
entitled to cast not less than 10 percent of the votes at such meeting.

        (b)  Any request for the calling of a special meeting of the
shareholders shall (1) be in writing, (2) specify the date and time thereof,
which date shall be not less than 35 nor more than 60 days after receipt of the
request, (3) specify the general nature of the business to be transacted
thereat and (4) be given either personally or by first-class mail, postage
prepaid, or other means of written communication to the Chairman of the Board,

receiving a proper request to call a special meeting of the shareholders shall
cause notice to be given pursuant to the provisions of Section 4 of this
article to the shareholders entitled to vote thereat that a meeting will be
held at the date and time specified by the person or persons calling the
meeting. If notice is not given within 20 days of the receipt of the request,
the shareholders making the request may give notice of such meeting so long as
the notice given complies with the other provisions of this subsection.

        (c)  No business may be transacted at a special meeting unless the
general nature thereof was stated in the notice of such meeting.

        Section 4.  Notice of Annual, Special or Adjourned Meetings.  (a)
Whenever any meeting of the shareholders is to be held, a written notice of
such meeting shall be given in the manner described in subdivision (d) of this
section not less than 10 nor more than 60 days before the date thereof to each
shareholder entitled to vote thereat. The notice shall state the place, date
and hour of the meeting and (1) in the case of a special meeting, the general
nature of the business to be transacted or (2) in the case of the annual
meeting, those matters which the Board of Directors, at the time of the giving
of the notice, intends to present for action by the shareholders. The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, management intends to
present for election.

        (b)  Any proper matter may be presented at an annual meeting for action.
However, any action to approve (1) a contract or transaction in which a
director has a direct or indirect financial interest under Section 310 of the
Corporations Code of California, (2) an amendment of the articles


                                      2


<PAGE>   7
of incorporation under Section 902 of that code, (3) a reorganization of the
corporation, under Section 1201 of that code, (4) a voluntary dissolution of
the corporation under Section 1900 of that code, or (5) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares under Section 2007 of that code may be taken only if the notice of the
meeting states the general nature of the matter to be approved.

        (c)  Notice need not be given of an adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken,
except that if the adjournment is for more than 45 days or if after the
adjournment a new record date is provided for the adjourned meeting, a notice
of the adjourned meeting shall be given to each shareholder of record entitled
to vote at that meeting.

        (d)  Notice of any meeting of the shareholders shall be given
personally, by first class mail, or by telegraph or other written
communication, addressed to the shareholder at his address appearing on the
books of the Corporation or given by him to the Corporation for the purpose of
notice; or if no such address appears or is given, at the place where the
principal executive office of the Corporation is located or by publication at
least once in a newspaper of general circulation in the county in which the
principal executive office is located.  Notice shall be deemed to have been
given at the time when delivered personally to the recipient, deposited in the
mail, delivered to a common carrier for transmission to the recipient or sent
by other means of written communication.  An affidavit of the mailing or other
means of giving notice may be executed by the Secretary, assistant secretary or
any transfer agent of the Corporation giving the notice and shall be prima
facie evidence of the giving of the notice.  Such affidavits shall be filed and
maintained in the minute books of the Corporation.

        (e)  If any notice or report addressed to the shareholder at his
address appearing on the books of the Corporation is returned to the
Corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice or report to the
shareholder at such address, all future notices or reports shall be deemed to
have been duly given without further mailing if the same shall be available for
the shareholder upon his written demand at the principal executive office of
the Corporation for a period of one year from the date of the giving of the
notice or report to all other shareholders.

        Section 5.  Record Date.  (a) The Board of Directors may fix a time in
the future as a record date for




                                      3
<PAGE>   8
determination of the shareholders (1) entitled to notice of any meeting or to
vote thereat, (2) entitled to give written consent to any corporate action
without a meeting, (3) entitled to receive payment of any dividend or other
distribution or allotment of any rights or (4) entitled to exercise any rights
in respect of any other lawful action.  The record date so fixed shall be not
more than 60 nor less than 10 days prior to the date of any meeting of the
shareholders nor more than 60 days prior to any other action.

        (b)  In the event no record date is fixed:

             (1)  The record date for determining the shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given
or, if notice is waived, at the close of business on the business day next
preceding the day on which the meeting is held.

             (2)  The record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors has been taken, shall be the day on which the first
written consent is given.

             (3)  The record date for determining shareholders for any other 
purpose shall be at the close of business on the day on which the Board of 
Directors adopts the resolution relating thereto, or the 60th day prior to 
the date of such other action, whichever is later.

        (c)  Only shareholders of record on the close of business on the record
date are entitled to notice and to vote, to give written consent or to receive
a dividend, distribution or allotment of rights or to exercise the rights, as
the case may be, notwithstanding any transfer of any shares on the books of the
Corporation after the record date.

        (d)  A determination of shareholders of record entitled to notice of or
to vote at a meeting of shareholders shall apply to any adjournment of the
meeting unless the Board of Directors fixes a new record date for the adjourned
meeting, but the Board shall fix a new record date if the meeting is adjourned
for more than 45 days from the date set for the original meeting.

        Section 6.  Quorum.  (a) A majority of the shares entitled to vote at a
meeting of the shareholders, represented in person or by proxy, shall
constitute a quorum for the transaction of business thereat.



                                      4
<PAGE>   9
        (b)  The shareholders present at a duly called or held meeting at which
a quorum is present may continue to transact business until adjournment
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum, if any action taken (other than adjournment) is approved by at least a
majority of the shares required to constitute a quorum.

        Section 7.  Adjournment.  Any meeting of the shareholders may be
adjourned from time to time whether or not a quorum is present by the vote of a
majority of the shares represented thereat either in person or by proxy. At the
adjourned meeting the Corporation may transact any business which might have
been transacted at the original meeting.

        Section 8.  Validation of Actions Taken at Defectively Called, Noticed
or Held Meetings.  (a) The transactions of any meeting of the shareholders,
however called and noticed, and wherever held, are as valid as though had at a
meeting duly held after regular call and notice, if a quorum is present either
in person or by proxy, and if, either before or after the meeting, each of the
persons entitled to vote thereat, not present in person or by proxy, signs a
written waiver of notice or a consent to the holding of the meeting or an
approval of the minutes thereof. Any written waiver of notice shall comply with
subdivision (f) of Section 601 of the Corporations Code of the State of
California. All such waivers, consents and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

        (b)  Attendance of a person at a meeting shall constitute a waiver of
notice of and presence at such meeting, except (1) when the person objects, at
the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened and (2) that attendance at a meeting
is not a waiver of any right to object to the consideration of any matter
required by the General Corporation Law of the State of California to be
included in the notice but not so included, if such objection is expressly made
at the meeting.

        Section 9.  Voting for Election of Directors. (a) Except as provided in
subdivision (c) of this section, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting at which a quorum is
present (which shares voting affirmatively also constitute at least a majority
of the required quorum) shall be the act of the shareholders, unless the vote
of a greater number is required by law or the Articles of Incorporation.


                                      5




<PAGE>   10
        (b)  Every shareholder complying with subdivision (c) of this section
and entitled to vote at any election of directors may cumulate his votes and
give one candidate a number of votes equal to the number of directors to be
elected multiplied by the number of votes to which his shares are normally
entitled, or distribute his votes on the same principle among as many
candidates as he thinks fit.

        (c)  No shareholder shall be entitled to cumulate his votes (i.e., cast
for any candidate a number of votes greater than the number of votes which such
shareholder normally is entitled to cast) unless the candidate's or candidates'
names for which he desires to cumulate his votes have been placed in nomination
prior to the voting and the shareholder has given notice at the meeting prior
to the voting of his intention to cumulate his votes. If any one shareholder
has given such notice, all shareholders may cumulate their votes for candidates
in nomination.

        (d)  Elections for directors may be by voice vote or by ballot unless
any shareholder entitled to vote demands election by ballot at the meeting
prior to the voting, in which case the vote shall be by ballot.

        (e)  In any election of directors, the candidates receiving the highest
number of affirmative votes of the shares entitled to be voted for them up to
the number of directors to be elected by such shares are elected as directors.

        Section 10.  Proxies.  (a) Every person entitled to vote shares may
authorize another person or persons to act with respect to such shares by a
written proxy signed by him or his attorney-in-fact and filed with the
Secretary of the Corporation. A proxy shall be deemed signed if the
shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by him or his
attorney-in-fact.

        (b)  Any validly executed proxy, except a proxy which is irrevocable
pursuant to subdivision (c) of this section, shall continue in full force and
effect until the expiration of the term specified therein or upon its earlier
revocation by the person executing it prior to the vote pursuant thereto (1) by
a writing delivered to the Corporation stating that it is revoked, (2) by
written notice of death of the person executing the proxy, delivered to the
Corporation, (3) by a subsequent proxy executed by the person executing the
prior proxy and presented to the meeting or (4) as to any meeting by attendance
at such meeting and voting in person by the person executing the proxy. No
proxy shall be 


                                      6


<PAGE>   11
valid after the expiration of 11 months from the date thereof unless otherwise
provided in the proxy. The date contained on the form of proxy shall be deemed
to be the date of its execution.

        (c)  A proxy which states that it is irrevocable is irrevocable for the
period specified therein subject to the provisions of subdivisions (e) and (f)
of Section 705 of the Corporations Code of the State of California.

        Section 11.  Inspectors of Election.  (a) In advance of any meeting of
the shareholders, the Board of Directors may appoint either one or three
persons (other than nominees for the office of director) as inspectors of
election to act at such meeting or any adjournments thereof. If inspectors of
election are not so appointed, or if any person so appointed fails to appear or
refuses to act, the chairman of any such meeting may, and on the request of any
shareholder or his proxy shall, appoint inspectors of election (or persons to
replace those who so fail or refuse to act) at the meeting. If appointed at a
meeting on the request of one or more shareholders or the proxies thereof, the
majority of shares represented in person or by proxy shall determine whether
one or three inspectors are to be appointed.

        (b)  The duties of inspectors of election and the manner of performance
thereof shall be as prescribed in subdivisions (b) and (c) of Section 707 of
the Corporations Code of the State of California.

        Section 12.  Action by Written Consent.  (a) Subject to subdivisions
(b) and (c) of this section, any action which may be taken at any annual or
special meeting of the shareholders may be taken without a meeting, without a
vote and without prior notice, if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding shares having not less
than the minimum number of votes which would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted. All such consents shall be filed with the Secretary of the
Corporation and maintained with the corporate records.

        (b)  Except for the election of a director by written consent to fill a
vacancy (other than a vacancy created by removal), directors may be elected by
written consent only by the unanimous written consent of all shares entitled to
vote for the election of directors. In the case of an election of a director by
written consent to fill a vacancy (other than a vacancy created by removal),
any such election requires the consent of a majority of the outstanding shares
entitled to vote for the election of directors.


                                      7


<PAGE>   12
        (c)  Unless the consents of all shareholders entitled to vote have been
solicited in writing, the secretary shall give prompt notice of the corporate
action approved by the shareholders without a meeting.  This notice shall be
given in the manner specified in subdivision (d) of Section 4 of this Article
III.  In the case of approval of (1) contracts or transactions in which a
director has a direct or indirect financial interest under Section 310 of the
Corporations Code of California, (2) indemnification of agents of the
corporation, under Section 317 of that code, (3) a reorganization of the
corporation, under Section 1201 of that code, or (4) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares, under Section 2007 of that code, notice of such approval shall be given
at least ten (10) days before the consummation of any action authorized by that
approval.

        (d)  Any shareholder giving a written consent, or his proxyholders, or
a transferee of the shares or a personal representative of the shareholder or
their respective proxyholders, may revoke the consent by a writing received by
the Corporation prior to the time that written consents of the number of shares
required to authorize the proposed action have been filed with the Secretary of
the Corporation, but may not do so thereafter.  Such revocation is effective
upon its receipt by the Secretary of the Corporation.

                                  ARTICLE IV

                                  DIRECTORS

        Section 1.  Number of Directors.  (a) The authorized number of
directors shall depend upon the number of shareholders.  If there is only one
shareholder, then there will only be one director.  Whenever there is more than
one shareholder, then there will be no less than seven nor more than thirteen
directors.  The exact number of directors shall be fixed from time to time,
within the limits specified in this subdivision, by an amendment of subdivision
(b) of this section adopted by the Board of Directors.

        (b)  The exact number of directors shall be one (1) until changed as

        Section 9.  PAYMENT OF EXPENSES IN ADVANCE.  Expenses incurred in
defending any civil or criminal action or proceeding for which indemnification
is required pursuant to Section 7 or for which indemnification is permitted
pursuant to Section 8 following authorization thereof by the Board of
Directors, in the case of directors shall and in the case of other agents of
the corporation entitled to indemnification may, be paid by the corporation in
advance of the final disposition of such action or proceeding upon receipt of
an undertaking by or on behalf of the indemnified party to repay such amount if
it shall ultimately be determined that the indemnified party is not entitled to
be indemnified as authorized in this Article IX.

        Section 10.  INDEMNITY NOT EXCLUSIVE.  The indemnification provided by
this Article IX shall not be deemed exclusive of any other rights to which
those seeking indemnification may be entitled under any bylaw, agreement, vote
of shareholders or disinterested directors or otherwise, both as to action in
an official capacity and as to action in another capacity while holding such
office, to the extent that such additional rights to indemnification are
authorized in the Articles of Incorporation.

        Section 11.  INSURANCE INDEMNIFICATION.  The corporation shall have the
power to purchase and maintain insurance on behalf of any person who is or was
an agent of the corporation against any liability asserted against or incurred
by such person in such capacity or arising out of such person's status as such,
whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this Article IX.

        Section 12.  CONFLICTS.  No indemnification or advance shall be made
under this Article IX, except where such indemnification or advance is mandated
by law or the order, judgment or decree of any court of competent jurisdiction,
in any circumstance where it appears:

                (1)  That it would be inconsistent with a provision of the
Articles of Incorporation, these bylaws, a resolution of the shareholders of an
agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

                (2)  That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

                 2. Exercise of Warrant.

                 2.1 Manner of Exercise. This Warrant may be exercised by the
Holder hereof, in whole or in part, during normal business hours on any Business
Day, by surrender of this Warrant to the Company at its office maintained
pursuant to Section 9, accompanied by a subscription in substantially the form
attached to this Warrant (or a reasonable facsimile thereof), duly executed by
such Holder and, in the case of clause (a) below, accompanied by payment of the
aggregate Exercise Price of the number of shares of Common Stock designated in
such subscription. Payment of such Exercise Price may be made, at the option of
the Holder (a) in cash, by certified or official bank check payable to the order
of the Company, or (b) by the Company withholding that number of shares of
Common Stock with an aggregate Closing Price as of the date of exercise equal to
such aggregate Exercise Price.


                                       2
<PAGE>   3

                 2.2 When Exercise Effective. Each exercise of this Warrant
shall be deemed to have been effected immediately prior to the close of business
on the Business Day on which this Warrant and the accompanying subscription
shall have been duly surrendered to the Company as provided in Section 2.1, and
at such time the Holder shall be deemed to have become the holder of record of a
number of shares of Common Stock equal to the number of shares designated in
such subscription less, in the case of clause 2.1(b), the number of shares of
Common Stock withheld by the Company as payment therefor.

                 2.3 Delivery of Stock Certificates, etc. As soon as practicable
after each exercise of this Warrant, in whole or in part, in accordance with the
terms of Section 2.1, the Company shall cause to be issued in the name of the
Holder (or its designee), and delivered to the Holder (or at its direction),

                          (a) a certificate or certificates for the number of
duly authorized, validly issued, fully paid and nonassessable shares of Common
Stock to which such Holder shall be entitled upon such exercise plus, in lieu of
any fractional share to which such Holder would otherwise be entitled, cash in
an amount equal to the same fraction of the Closing Price per share on the date
of such exercise, and

                          (b) in case such exercise is in part only, a new
Warrant of like tenor, calling in the aggregate on the face or faces thereof for
the number of shares of Common Stock equal to the number of such shares called
for on the face of this Warrant (after giving effect to any adjustment thereof
after the date hereof) minus the number of such shares designated by the Holder
upon such exercise as provided in Section 2.1.

                 3. Adjustments.

                 3.1 General. The number of shares of Common Stock that the
Holder shall be entitled to receive upon each exercise hereof shall be
determined by multiplying the number of shares of Common Stock that would
otherwise (but for the provisions of this Section 3) be issuable upon such
exercise, by a fraction (i) the numerator of which is $0.75 and (ii) the
denominator of which is the Exercise Price on the date of such exercise.

                 The "Exercise Price" shall initially be $0.75 per share;
provided, that the Exercise Price shall be adjusted and readjusted from time to
time as provided in this Section 3; provided, however, that no such adjustment
shall be made to the Exercise Price in connection with the issuance of (i) up to
1,495,000 shares of Common Stock to the chairman and chief executive officer of
the Company on or prior to May 17, 1996, (ii) warrants to purchase shares of
Common Stock to General Electric Company, a New York corporation acting through
GE Medical Systems ("GE") on or prior to May 17, 1996, and (iii) options granted
to members of management (other than the chairman and chief executive officer)
pursuant to an incentive stock option plan approved by a majority of the
Company's shareholders to purchase up to five percent (5%) of the fully-diluted
shares of Common Stock outstanding on the date of adoption of the plan.

                 3.2 Stock Dividends. If, after the date hereof, the Company
shall declare or pay any dividend on the Common Stock payable in Common Stock,
then, and in each such case, the Exercise Price shall be reduced, as of the
close of business on the Record Date, by multiplying such Exercise Price by a
fraction (a) the numerator of which shall be the number of shares of Common
Stock outstanding at the close of business on such Record Date


                                        3
<PAGE>   4

and (b) the denominator of which shall be the sum of such number of shares and
the total number of shares constituting such dividend or other distribution.

                 3.3 Rights. If, after the date hereof, the Company shall pay or
make a dividend or other distribution on its Common Stock consisting exclusively
of, or shall otherwise issue to all holders of its Common Stock, rights or
warrants entitling the holders thereof to subscribe for or purchase shares of
Common Stock at a price per share less than the Current Market Price on the
Record Date, the Exercise Price shall be reduced, as of the close of business on
the Record Date, by multiplying such Exercise Price by a fraction (a) the
numerator of which shall be the number of shares of Common Stock outstanding at
the close of business on such Record Date plus the number of shares of Common
Stock that the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
Closing Price and (b) the denominator of which shall be the number of shares of
Common Stock outstanding at the close of business on such record date plus the
number of shares of Common Stock so offered for subscription or purchase. For
purposes of this Section 3.3, the issuance of rights or warrants to subscribe
for or purchase stock or securities convertible into shares of Common Stock
shall be deemed to be the issuance of rights or warrants to purchase the shares
of Common Stock into which such stock or securities are convertible at an
aggregate offering price equal to the aggregate offering price of such stock or
securities plus the minimum aggregate amount (if any) payable upon conversion of
such stock or securities into Common Stock.

                 3.4 Stock Splits, etc. If, after the date hereof, the
outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock or combined into a smaller number of shares of Common
Stock by stock split, combination, reclassification or otherwise, the Exercise
Price in effect at the close of business on the day upon which such subdivision
or combination becomes effective shall be proportionately reduced or increased,
such reduction or increase, as the case may be, to become effective immediately
prior to the opening of business on the day following the day upon which such
subdivision or combination becomes effective.

                 3.5 Other Distributions. If, after the date hereof, the Company
shall, by dividend or otherwise, distribute to all holders of record of its
Common Stock evidences of indebtedness, shares of capital stock, cash or assets
(including securities, but excluding any dividend or distribution for which an
adjustment is made pursuant to Section 3.2 or 3.3 above), the Exercise Price
shall be reduced, as of the close of business on the Record Date, by multiplying
such Exercise Price by a fraction (a) the numerator of which shall be the
Closing Price per share of Common Stock on the Record Date less the fair market
value on such Record Date, of such evidences of indebtedness, shares of capital
stock, cash and assets that are distributed to a holder of one share of Common
Stock and (b) the denominator of which shall be such Closing Price per share of
the Common Stock. For purposes of this Section 3.5, any dividend or distribution
that includes shares of Common Stock or rights or warrants to subscribe for or
purchase shares of Common Stock shall be deemed instead to be (1) a dividend or
distribution of the evidences of indebtedness, cash, assets or shares of capital
stock other that such shares of Common Stock, rights or warrants (so that any
Exercise Price reduction required by this Section 3.5 is made) immediately
followed by (2) a dividend or distribution of such shares of Common Stock,
rights or warrants (so that there is made any further Exercise Price reduction
required by Section 3.2 or 3.3 hereof).

                 In lieu of any adjustment to the Exercise Price provided for in
this Section 3.5, the Holder may elect, in its sole discretion, to receive such
dividend or distribution as would be received by a holder of the number


                                        4

<PAGE>   5

of shares of Common Stock issuable upon the exercise of this Warrant. Such
dividend or distribution shall be declared, ordered, made or paid at the time
such dividend or distribution is declared, ordered, made or paid on the Common
Stock, without any requirement of any exercise hereof.

                 3.6 Sales Below Market Price. If, after the date hereof, the
Company shall issue or sell its shares of Common Stock for consideration per
share that is less than the Current Market Price on the Trading Day next
preceding the date of such issuance (unless (i) the provisions of 3.2, 3.3, 3.4
or 3.5 shall be applicable, (ii) such issuance or sale is in connection with a
bona fide underwritten public offering, or (iii) such issuance or sale is in
consideration for assets or ownership interests acquired by the Company in an
arm's length transaction with a bona fide third party) the Exercise Price shall
be adjusted to equal the product of the Exercise Price in effect immediately
prior to such action, multiplied by a fraction (a) the numerator of which is the
Adjusted Fair Market Value per share and (b) the denominator of which is such
Current Market Price.

                 "Adjusted Fair Market Value" shall mean (i) the sum of (x) the
product of (A) the number of shares of Common Stock outstanding immediately
prior to such issue or sale times (B) the Current Market Price, plus (y) the
consideration, if any, received by the Company upon such issue or sale, divided
by (ii) the number of shares of Common Stock outstanding immediately after such
issue or sale.

                 3.7 Minimum Adjustment of Warrant Price. If the amount of any
adjustment of the Exercise Price required pursuant to this Section 3 would be
less than one percent (1%) of the Exercise Price in effect at the time such
adjustment is otherwise so required to be made, such amount shall be carried
forward and adjustment with respect thereto made at the time of and together
with any subsequent adjustment which, together with such amount and any other
amount or amounts so carried forward, shall aggregate at least one percent (1%)
of such Exercise Price, provided, that all such adjustments required pursuant to
Section 3 and carried forward under this Section 3.7 shall be made upon (and in
connection with) any exercise of the Warrant.

                 3.8 Form of Warrants. Irrespective of any adjustments in the
Exercise Price or the number of shares of Common Stock purchasable upon the
exercise of this Warrant, this Warrant (and any Warrant hereafter issued) may
continue to express the same price and number and kind of shares as are stated
in the Warrant initially issued.

                 4. Consolidation, Merger, etc. If, after the date hereof, the
Company shall

                          (a) consolidate with or merge into any other Person
and shall not be the continuing or surviving corporation of such consolidation
or merger, or

                          (b) permit any other Person to consolidate with or
merge into the Company and the Company shall be the continuing or surviving
Person but, in connection with such consolidation or merger, the Common Stock
shall be changed into or exchanged for stock or other securities of any other
Person or cash or any other property, or

                          (c) effect a capital reorganization or
reclassification of the Common Stock,


                                        5
<PAGE>   6

then (i) lawful and adequate provision shall be made so that, upon the basis and
the terms and in the manner provided in this Warrant, the Holder of this
Warrant, upon the exercise hereof after the consummation of such transaction,
shall be entitled to receive, in lieu of the Common Stock issuable upon such
exercise, the kind and amount of securities, cash or other property to which
such Holder would have been entitled upon such consummation if such Holder had
exercised the rights represented by this Warrant in full immediately prior
thereto and (ii) appropriate provision shall be made with respect to rights and
interests of the Holder to the end that the provisions hereof (including without
limitation provisions for adjustment of the Exercise Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of any conversion rights
hereunder.

                 5. Certain Covenants. The Company shall (a) not permit the par
value of any shares of stock receivable upon the exercise of this Warrant to
exceed the amount payable therefor upon such exercise, and (b) take all such
action as may be necessary or appropriate to validly and legally issue fully
paid and nonassessable shares of stock on the exercise of this Warrant.

                 6. Accountants' Report as to Adjustments. Upon the occurrence
of any event requiring adjustment or readjustment in the Exercise Price or the
shares of Common Stock issuable upon the exercise of this Warrant, the Company
will promptly compute such adjustment or readjustment in accordance with the
terms of this Warrant and cause independent certified public accountants of
recognized national standing (which may be the regular auditors of the Company)
to verify such computation and prepare a report setting forth such adjustment or
readjustment and showing in reasonable detail the method of calculation thereof
and the facts upon which such adjustment or readjustment is based. The Company
will promptly mail a copy of each such report to the Holder.

                 7. Payment of Taxes. The Company shall pay any and all issue or
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock upon exercise of the Warrants. The Company shall not, however, be
required to pay any tax payable in respect of any transfer involved in the issue
or delivery of Warrants or shares of Common Stock issued upon exercise of the
Warrants (or other securities or assets) in a name other than that in which the
Warrants so exercised were registered.

                 8. Reservation of Stock, etc. The Company shall at all times
reserve and keep available, solely for issuance and delivery upon exercise of
this Warrant, the number of shares of Common Stock from time to time issuable
upon exercise of this Warrant. All shares of Common Stock issuable upon exercise
of this Warrant shall be duly authorized and, when issued upon such exercise in
accordance with the terms hereof, shall be validly issued, fully paid and
nonassessable, with no liability on the part of the holders thereof.

                 9. Ownership and Transfer.

                          (a) The Company shall treat the person in whose name
this Warrant is registered on the register (the "Warrant Register") kept at the
office of the Company maintained pursuant to this Section 9 as the owner and

                          (b) This Warrant shall be transferable only on the
Warrant Register, upon delivery hereof, accompanied by a written instrument or
instruments of transfer, duly executed by the registered Holder hereof or

order of the Holder hereof a new Warrant or Warrants of like tenor, in the name
of such Holder or as such Holder may direct, calling in the aggregate on the
face or faces thereof for the number of shares of Common Stock called for on the
face hereof.

                          (c) The Company will maintain an office in the State
of California, which office shall initially be at Four Embarcadero Center, Suite
3620, San Francisco, California 94111-4115, until such time as the Company shall
notify the Holder of any change of location of such office.

                          (d) If any warrant certificate shall be mutilated,
lost, stolen or destroyed, the Company shall issue and deliver in exchange and
substitution for and upon cancellation of the mutilated certificate, or in lieu

theft of any certificate and such security or indemnity as may reasonably be
required by them to save each of them and any of their agents harmless, to issue
a new certificate of like tenor and representing an equivalent right or
interest.

                 10. No Rights or Liabilities as Stockholder. Nothing contained
in this Warrant shall be construed as conferring upon the Holder any rights as a
stockholder of the Company or as imposing any obligation on such Holder to
purchase any securities or as imposing any liabilities on such Holder as a
stockholder of the Company, whether such obligation or liabilities are asserted
by the Company or by creditors of the Company.

                 11. Notices. All notices, demands, requests, consents,

below, and this Warrant are received by the Company as described above and all
taxes required to be paid by Holder, if any, pursuant to Section 2.2 prior to
the issuance of such shares have been paid or agreed to be paid when finally
determined.

                 Payment of the Warrant Price shall be made by check.

         2.2 Payment of Taxes. All shares of Common Stock issuable upon the
exercise of this Warrant pursuant to the terms hereof shall be validly issued,
fully paid and nonassessable. The Company shall pay all expenses in connection
with, and all taxes and other governmental charges that may be imposed with
respect to, the issue or delivery thereof, unless such tax or charge is imposed
by law upon Holder, in which case such taxes or charges shall be paid by Holder.
The Company shall not be required, however, to pay any tax or other charge
imposed in connection with any transfer involved in the issuance of any
certificate for shares of Common Stock issuable upon exercise of this Warrant in
any name other than that of Holder, and in such case the Company shall not be
required to issue or deliver any stock certificate until such tax or other
charge has been paid or it has been established to the satisfaction of the
Company that no such tax or other charge is due.

         2.3 Fractional Shares. The Company shall not issue a fractional share
of Common Stock upon exercise of this Warrant. A fractional share otherwise
issuable shall be rounded up to the nearest whole share.

         2.4 Continued Validity. A holder of shares of Common Stock issued upon
the exercise of this Warrant (other than a holder who acquires such shares after
the same have been publicly sold pursuant to a Registration Statement under the
Securities Act or sold pursuant to Rule 144 thereunder) shall continue to be
entitled with respect to such shares to all rights to which it would have been
entitled as Holder under Sections 9, 10, 13, and 16 of this

                                       -5-

Warrant. The Company shall, at the time of each exercise of this Warrant upon
the request of the holder of the shares of Common Stock issued upon such
exercise hereof, acknowledge in writing, in form reasonably satisfactory to such
holder, its continuing obligation to afford to such holder all such rights;
provided, however, that if such holder shall fail to make any such request, such
failure shall not affect the continuing obligation of the Company to afford to
such holder all such rights.

3.       TRANSFER, DIVISION AND COMBINATION

         3.1 Transfer. This Warrant shall be nontransferable other than to a
division, subsidiary or affiliate of GE Medical except by merger of the Holder
with another entity or otherwise as specifically contemplated in Section 9
hereof or by operation of law. Subject to compliance with Section 9, transfer of
this Warrant and all rights hereunder, in whole or in part, shall be registered
on the books of the Company to be maintained for such purpose, upon surrender of
this Warrant at the principal office of the Company referred to in Section 2.1
or the office or agency designated by the Company pursuant to Section 12,
together with a written assignment of this Warrant substantially in the form of
Exhibit B hereto duly executed by Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such transfer.
Upon such surrender and, if required, such payment, the Company shall, subject
to Section 9, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination specified in such instrument of
assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A
Warrant, if properly assigned in compliance with Section 9, may be exercised by
a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued. If requested by the Company, a new Holder shall acknowledge in
writing, in form reasonably satisfactory to the Company, such Holder's
continuing obligations under Section 9 of this Warrant.

         3.2 Division and Combination. Subject to Section 9, this Warrant may be
divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by Holder or its agent or attorney. Subject to compliance with Section
3.1 and with Section 9, as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

<PAGE>   10



         3.3 Expenses. The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 3.

         3.4 Maintenance of Books. The Company shall maintain, at its aforesaid
office or agency, books for the registration, and the registration of transfer,
of this Warrant.

4.       ADJUSTMENTS

         The number of shares of Common Stock for which this Warrant is
exercisable, or the price at which such shares may be purchased upon exercise of
this Warrant shall be subject to adjustment from time to time as set forth in
this Section 4. The Company shall give each Holder notice of any event described
below which requires an adjustment pursuant to this Section 4 at the time of
such event.

         4.1 Stock Dividends, Subdivisions, Combinations and Reclassification.
If at any time the Company shall with respect to its Common Stock or Convertible
Securities:

                 (a) pay a dividend or make distribution of Additional Shares of
         Common Stock or Convertible Securities other than convertible
         indebtedness or convertible Preferred Stock (in which event such
         Additional Shares of Common Stock issuable upon exchange or conversion
         shall be deemed distributed),

                 (b) subdivide its outstanding shares of Common Stock into a
         larger number of shares of Common Stock,

                 (c) combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock, or

                 (d) reclassify its Common Stock (other than a change in par
         value, or from par value to no par value) into shares of Common Stock
         and shares of any other class of stock; and, if the Outstanding shares
         of Common Stock shall be changed into a larger or smaller number of
         shares of Common Stock as a part of such reclassification, such change
         shall be deemed a subdivision or combination, as the case may be, of
         the Outstanding shares of Common Stock within the meaning of this
         Section 4.1.,

then (i) the number of shares of Common Stock for which this Warrant is
exercisable after the occurrence of any such event shall be equal to (A) the
maximum number of shares of Common Stock underlying this Warrant prior to the
occurrence of any such event, multiplied by (B) the number of Fully Diluted
Outstanding shares of Common Stock after any such event, divided by the number
of Fully Diluted Outstanding shares of Common Stock prior to any such event, and
(ii) the Current Warrant Price shall be adjusted to equal the Current Warrant
Price multiplied (A) by the number of shares of

                                       -7-


<PAGE>   11



Common Stock for which this Warrant is exercisable immediately prior to the
adjustment divided by (B) the number of shares for which this Warrant is
exercisable immediately after such adjustment. Any increased number of shares of
Common Stock subject to this Warrant resulting from application of the foregoing
shall be allocated ratably among all shares of Common Stock subject to this
Warrant prior to each such event and the shares (including the newly allocated
shares) not subject to clause (i) of Section 2.1 shall remain subject to the
conditions precedent to exercise described in clause (ii) of Section 2.1.

         4.2 Other Provisions Applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable provided
for in this Section 4:

                 (a) When Adjustments to Be Made. The adjustments required by
         this Section 4 shall be made whenever and as often as any specified
         event requiring an adjustment shall occur. For the purpose of any
         adjustment, any specified event shall be deemed to have occurred at the
         close of business on the date of its occurrence.

                 (b) When Adjustment Not Required. If the Company shall take a
         record of the holders of its Common Stock for the purpose of entitling
         them to receive a dividend or distribution or subscription or purchase
         rights and shall, thereafter and before the distribution to
         stockholders thereof, legally abandon its plan to pay or deliver such
         dividend, distribution, subscription or purchase rights, then
         thereafter no adjustment shall be required by reason of the taking of
         such record and any such adjustment previously made in respect thereof
         shall be rescinded and annulled.

5.       NOTICES TO WARRANT HOLDERS

         5.1 Notice of Adjustments. Whenever the number of shares of Common
Stock for which this Warrant is exercisable, or whenever the price at which a
share of such Common Stock may be purchased upon exercise of this Warrant, shall
be adjusted pursuant to Section 4, the Company shall forthwith prepare a
certificate to be executed by the chief financial officer of the Company setting
forth, in reasonable detail, the event requiring the adjustment and the method
by which such adjustment was calculated, specifying the number of shares of
Common Stock for which this Warrant is exercisable, and any change in the
purchase price or prices thereof, after giving effect to such adjustment or
change. The Company shall promptly cause a signed copy of such certificate to be
delivered to each Holder in accordance with Section 16.2. The Company shall keep
at its office or agency designated pursuant to Section 12 copies of all such
certificates and cause the same to be available for inspection at said office
during normal business

                                       -8-


<PAGE>   12



hours by any Holder or any prospective purchaser of a Warrant designated by a
Holder thereof.

         5.2 Notice of Certain Corporate Action. The Holder shall be entitled to
the same rights to receive notice of corporate action as any holder of Common
Stock.

6.       NO IMPAIRMENT

         The Company shall not by any action including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
against impairment. Without limiting the generality of the foregoing, the
Company will (a) not increase the par value, if any, of any shares of Common
Stock receivable upon the exercise of this Warrant above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (b)
take all such action as may be reasonably necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use its best efforts to
obtain all such authorizations, exemptions or consents from any public
regulatory body having jurisdiction thereof as may be necessary to enable the
Company to perform its obligations under this Warrant.

         Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form satisfactory
to Holder, the continuing validity of this Warrant and the obligations of the
Company hereunder.

7.       RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
         APPROVAL OF ANY GOVERNMENTAL AUTHORITY

         From and after the Closing Date, the Company shall at all times reserve
and keep available for issuance upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of all outstanding Warrants. All shares of Common Stock
which shall be so issuable, when issued upon exercise of any Warrant and payment
therefor in accordance with the terms of such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.

         Before taking any action which would cause an adjustment reducing the
Current Warrant Price below the then par value, if any, of the shares of Common
Stock issuable upon exercise of the Warrants, the Company shall take any
corporate action which may be

                                       -9-


<PAGE>   13



reasonably necessary in order that the Company may validly and legally issue
fully paid and nonassessable shares of such Common Stock at such adjusted
Current Warrant Price.

         Before taking any action which would result in an adjustment in the
number of shares of Common Stock for which this Warrant is exercisable or in the
Current Warrant Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be reasonably necessary from any
public regulatory body or bodies having jurisdiction thereof.

         If any shares of Common Stock required to be reserved for issuance upon
exercise of warrants require registration or qualification with any governmental
authority under any federal or state law (otherwise than as provided in Section
9) before such shares may be so issued, the Company will in good faith and as
expeditiously as possible and at its expense endeavor to cause such shares to be
duly registered or qualified; provided that the provisions of Section 9 shall
govern with respect to Company's obligation to effect the registration of its
securities under the Securities Act.

8.       TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

         In the case of all dividends or other distributions by the Company to
the holders of its Common Stock with respect to which any provision of Section 4
refers to the taking of a record of such holders, the Company will in each such
case take such a record and will take such record as of the close of business on
a Business Day. The Company will not at any time, except upon dissolution,
liquidation or winding up of the Company, close its stock transfer books or
Warrant transfer books so as to result in preventing or delaying the exercise or
transfer of any Warrant.

9.       RESTRICTIONS ON TRANSFERABILITY

         This Warrant shall not be transferable except to a division, subsidiary
or affiliate of GE Medical or by merger of the Holder with another entity or
otherwise by operation of law. Furthermore, this Warrant and the Warrant Stock
shall not be transferred, hypothecated or assigned before satisfaction of the
conditions specified in this Section 9, which conditions are intended to ensure
compliance with the provisions of the Securities Act and state law, with respect
to the Transfer of this Warrant or any Warrant Stock. Holder, by acceptance of
this Warrant, agrees to be bound by the provisions of this Section 9.
Furthermore, Holder, by acceptance of this Warrant and by acceptance and
delivery of the Subscription Form in the form of Exhibit A hereto, represents
and warrants to the Company for its reliance in connection with issuing this
Warrant and the Warrant Stock, respectively, that (i) Holder is acquiring the
Warrant, and if applicable, the Warrant Stock for

                                      -10-


<PAGE>   14



Holder's own account for investment and not for sale or other disposition
thereof; (ii) Holder understands that such securities are not registered under
the Securities Act and must be held indefinitely unless subsequently registered
under the Securities Act or unless an exemption from such registration is
available; (iii) Holder, by reason of its business and financial experience has
the capacity to protect its own interests in connection with purchase and
transfer of such securities and is able to bear the economic risk thereof; and
(iv) the Company has made available to Holder all documents and information
regarding an investment in such securities requested by or on behalf of Holder,
including but not limited to all publicly available information on file with the
Commission.

         9.1     Restrictive Legend.

                 (a) Except as otherwise provided in this Section 9, each
         certificate for Warrant Stock initially issued upon the exercise of
         this Warrant, and each certificate for Warrant Stock issued to any
         subsequent transferee of any such certificate, shall be stamped or
         otherwise imprinted with a legend in substantially the following form:

                             The shares represented by this certificate have not
                             been registered under the Securities Act of 1933,
                             as amended, and are subject to the conditions
                             specified in a certain Common Stock Purchase
                             Warrant dated May 17, 1995, originally issued by
                             American Shared Hospital Services. No transfer of
                             the shares represented by this certificate shall be
                             valid or effective until such conditions and any
                             requirements of state law have been fulfilled. A
                             copy of the form of said Warrant is on file with
                             the Secretary of American Shared Hospital Services.
                             The holder of this certificate, by acceptance of
                             this certificate, agrees to be bound by the
                             provisions of such Warrant.

                             b) Except as otherwise provided in this Section 9,
                    each Warrant shall be stamped or otherwise imprinted with a
                    legend in substantially the following form:

                             This Common Stock Purchase Warrant and the
                             securities for which it can be exercised have not
                             been registered under the Securities Act of 1933,
                             as

                                      -11-


<PAGE>   15



                             amended, and may not be transferred in violation of
                             such Act or state law, the rules and regulations
                             thereunder or the transfer restrictions of this
                             Warrant.

          9.2 Notice of Proposed Transfers. Prior to any Transfer or attempted
Transfer of any Warrants or any shares of Warrant Stock, the holder of such
Warrants or Warrant Stock shall give 10 days prior written notice (a "Transfer
Notice") to the Company of such holder's intention to effect such Transfer,
describing the manner and circumstances of the proposed Transfer, and shall
obtain and deliver to the Company an opinion in form and substance reasonably
satisfactory to the Company (addressed to the Company and upon which the Company
may rely) from counsel to such holder who shall be reasonably satisfactory to
the Company, that the proposed Transfer of such Warrants or such Warrant Stock
may be effected without registration under the Securities Act and any applicable
state securities laws. After receipt of the Transfer Notice and opinion, the
Company shall, within five days thereof, so notify the holder of such Warrants
or Warrant Stock and such holder shall thereupon be entitled to Transfer such
Warrants or such Warrant Stock, in accordance with the terms of the Transfer
Notice. Each certificate, if any, evidencing such shares of Warrant Stock issued
upon such Transfer shall bear the restrictive legend set forth in Section
9.1(a), and each Warrant issued upon such Transfer shall bear the restrictive
legend set forth in Section 9.1(b), unless in the opinion of such counsel such
legend is not required in order to ensure compliance with the Securities Act and
any applicable state securities laws. The holder of the Warrants or the Warrant
Stock, as the case may be, giving the Transfer Notice shall not be entitled to
transfer and shall not transfer such Warrants or such Warrant Stock until (i)
the Company receives a written statement of investment intent and sophistication
from the proposed transferee of such Warrants or Warrant Stock in substance
substantially similar to clauses (i), (ii) and (iii) of the final sentence of
the first paragraph of Section 9 and (ii) such holder receives notice from the
Company under this Section 9.2.

          9.3 Termination of Restrictions. Notwithstanding the foregoing
provisions of Section 9, the restrictions imposed by this Section upon the
transferability after the Exercise Date of the Warrants and the Warrant Stock
and the legend requirements of Section 9.1 shall terminate as to any particular
Warrant or share of Warrant Stock (i) when and so long as such security shall
have been effectively registered under the Securities Act and disposed of
pursuant thereto or (ii) when the Company shall have received an opinion of
counsel reasonably satisfactory to it that such legend is not required in order
to ensure compliance with the Securities Act. Whenever after the Exercise Date
the restrictions imposed by Section 9 shall terminate as to this Warrant, as

                                      -12-


<PAGE>   16



hereinabove provided, the Holder hereof shall be entitled to receive from the
Company, at the expense of the Company, a new Warrant bearing the following
legend in place of the restrictive legend set forth hereon:

                           "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN
                           WARRANT CONTAINED IN SECTION 9 HEREOF TERMINATED
                           ON___________, ______, AND ARE OF NO FURTHER FORCE
                           AND EFFECT."

All Warrants thereafter issued upon registration of transfer, division or
combination of, or in substitution for, any Warrant or Warrants entitled to bear
such legend shall have a similar legend endorsed thereon. Whenever the
restrictions imposed by this Section shall terminate as to any share of Warrant
Stock, as hereinabove provided, the holder thereof shall be entitled to receive
from the Company, at the Company's expense, a new certificate representing such
Warrant Stock not bearing the restrictive legend set forth in Section 9.1(a).

10.       SUPPLYING INFORMATION

          The Company shall cooperate with each Holder of a Warrant and each
holder of Warrant Stock in supplying such information as may be reasonably
necessary for such Holder to complete and file any information reporting forms
presently or hereafter required by the Commission as a condition to the
availability of an exemption from the Securities Act for the sale of any Warrant
or Restricted Common Stock.

11.       LOSS OR MUTILATION

          Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and indemnity reasonably satisfactory to it (it being
understood that the written agreement of GE Medical shall be sufficient
indemnity) and in case of mutilation upon surrender and cancellation hereof, the
Company will execute and deliver in lieu hereof a new Warrant of like tenor to
such Holder; provided, in the case of mutilation, no indemnity shall be required
if this Warrant in identifiable form is surrendered to the Company for
cancellation.

12.       OFFICE OF THE COMPANY

         As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency (which shall initially be the principal executive
offices of the Company) where the Warrants may be presented for exercise,
registration of transfer, division or combination as provided in this Warrant.
The Company

                                      -13-


<PAGE>   17



shall notify Holder in writing prior to any change of the address of the office
at which the Warrants may be presented.

13.       FINANCIAL AND BUSINESS INFORMATION

          13.1 Information. Except during any period when the Company is a
Public Company (as hereinafter defined), it will deliver to each Holder, as soon
as practicable after the end of each month, and in any event within 30 days
thereafter, and after the end of each quarter and in any event within 45 days
thereafter, one copy of an unaudited consolidated balance sheet, statement of
income and statement of cash flow of the Company and its Subsidiaries for such
period setting forth in each case in comparative form the figures for the
corresponding periods in the previous fiscal years. Such financial statements
shall be prepared by the Company in accordance with GAAP and shall be
accompanied by the certification of the Company's chief executive officer or
chief financial officer that such financial statements are complete and correct
and present fairly the consolidated financial position, results of operations
and cash flow of the Company and its Subsidiaries as at the end of such period
and for such year-to-date period, as the case may be.

                    For purposes of this Section 13, the term "Public Company"
shall mean a company (i) that is subject to the reporting requirements of
Section 15(d) of the Exchange Act, or (ii) any of whose securities are
registered pursuant to Section 12(b) or 12(g) of the Exchange Act.

          13.2 Annual Information. Except during any period when the Company is
a Public Company, it will deliver to each Holder as soon as practicable after
the end of each fiscal year of the Company, and in any event within 90 days
thereafter, one copy of:

                             (i) an audited consolidated balance sheet of the
                    Company and its Subsidiaries as at the end of such year, and

                             (ii) audited consolidated statements of income and
                    retained earnings and cash flow of the Company and its
                    Subsidiaries for such year;

setting forth in each case in comparative form the figures for the corresponding
periods in the previous fiscal year; all prepared in accordance with GAAP, and
which audited financial statements shall be accompanied by (i) an opinion
thereon of the independent certified public accountants regularly retained by
the Company, or any other firm of independent certified public accountants of
recognized national standing selected by the Company and (ii) a report of such
independent certified public accountants confirming, or describing the agreed
upon procedures applied to the Company's schedules computing, any adjustment,
made pursuant

                                      -14-


<PAGE>   18



to Section 4 during such year. Such report shall include a description of any
errors determined by the accountants in the Company's schedules.

          13.3 Filings. The Company will file on or before the required date all
required regular or periodic reports (pursuant to the Exchange Act) with the
Commission and will deliver to Holder promptly upon their becoming available one
copy of each report, notice or proxy statement sent by the Company to its
stockholders generally, and of each regular or periodic report (pursuant to the
Exchange Act) and any Registration Statement, prospectus or written
communication (other than transmittal letters) pursuant to the Securities Act,
filed by the Company with (i) the Commission or (ii) any securities exchange on
which shares of Common Stock are listed (provided, however, that the Company may
request filing extensions pursuant to Rule 12b-25 under the Securities and
Exchange Act of 1934, as amended).

[14.      Intentionally Omitted.]

15.       LIMITATION OF LIABILITY

          No provision hereof, in the absence of affirmative action by the
Holder to purchase shares of Common Stock, and no enumeration herein of the
rights or privileges of Holder hereof, shall give rise to any liability of such

recipient, or three Business Days after the same shall have been deposited in
the United States mail. Failure or delay in delivering copies of any notice,
demand, request, approval, declaration, delivery or other communication to the

          16.3 Remedies. Each holder of Warrant and Warrant Stock, in addition
to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under Section 9
of this Warrant. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of Section 9 of this Warrant and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

          16.4 Successors and Assigns. Subject to the provisions of Sections 3.1
and 9, this Warrant and the rights evidenced hereby shall inure to the benefit
of and be binding upon the successors of the Company and the successors and
assigns of Holder. The provisions of this Warrant are intended to be for the
benefit of all Holders from time to time of this Warrant, and shall be
enforceable by any such Holder.

          16.5 Amendment. This Warrant and all other Warrants may be modified or
amended or the provisions hereof waived with the written consent of the Company
and the Holder, provided that no such Warrant may be modified or amended to
reduce the number of shares of Common Stock for which such Warrant is
exercisable or to increase the price at which such shares may be purchased upon
exercise of such Warrant (before giving effect to any adjustment as provided
therein) without the prior written consent of the Holder thereof.

          16.6 Severability. Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.

          16.7 Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part

                                      -17-


<PAGE>   21



laws of the state of the Company's incorporation applicable to contracts made
and performed in such state, without regard to the principles thereof regarding
conflict of laws, and any applicable laws of the United States of America.
Service of process on the Company or Holder in any action arising out of or
relating to this Agreement shall be effective if mailed to such party in
accordance with the procedures and requirements set forth in Section 16.2.

          16.9 MUTUAL WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN
CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY
RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE COMPANY AND HOLDER HEREOF
WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES),
THE COMPANY AND HOLDER HEREOF DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE
APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE
BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE COMPANY AND HOLDER
HEREOF WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION.

          IN WITNESS WHEREOF, the Company has caused this Warrant to be duly
executed and its corporate seal to be impressed hereon and attested by its

prepare and file with the SEC a Registration Statement under the Securities Act
for an offering to be made on a continuous basis pursuant to Rule 415 (or any
similar rule that may be adopted by the SEC) under the Securities Act covering
all the Registrable Securities (the "Shelf Registration").

                          (b)  The Shelf Registration shall be on Form S-1 or
another appropriate Form (reasonably acceptable to the holders of the
Registrable Securities offered thereby) permitting registration of such
Registrable Securities for resale by such holders in the manner or manners
designated by them (including, without limitation, one or more underwritten
offerings). The Company shall not permit any securities other than the
Registrable Securities to be included in the Shelf Registration.

                          (c)  The Company shall use its best efforts to cause
the Shelf Registration to become effective under the Securities Act on or prior
to 60 days after the filing thereof and shall keep the Shelf Registration
continuously effective for a period of 36 months from the date on which the
Shelf Registration becomes effective under the Securities Act (subject to
extension pursuant to Section 4(a) and Section 5 hereof), or such shorter period
that will terminate when all Registrable Securities covered by the Shelf
Registration have been sold. The Company shall also supplement or make
amendments to the Shelf Registration if required by the rules, regulations or

required by the Securities


                                        3
<PAGE>   4

Act or if reasonably requested by holders of a majority of the Registrable
Securities covered by the Shelf Registration or any underwriter of the
Registrable Securities.

                          (d)  If any of the Registrable Securities registered
pursuant to the Shelf Registration are to be sold in one or more firm commitment
underwritten offerings, and the managing underwriter advises the Shareholders of
such securities in writing that in its opinion the total number or dollar amount
of Registrable Securities proposed to be sold in such offering is such as to
materially and adversely affect the success of such offering, then there shall
be included in such firm commitment underwritten offering the number or dollar
amount of Registrable Securities held by the Shareholders that in the opinion of
such managing underwriter can be sold, and such Registrable Securities shall be
allocated pro rata on the basis of the number or dollar amount of securities
owned by each such Shareholder participating in such offering.

3.       Piggyback Registration

                          (a)  Right to Piggyback. If at any time the Company
proposes to file a registration statement under the Securities Act with respect
to an offering of any class of equity securities (other than a registration
statement (i) on Form S-4 or S-8 or any successor forms thereto, or (ii) filed
in connection with an offering made solely to employees of the Company), whether
or not for its own account, then the Company shall give written notice of such
proposed filing to the Shareholders of Registrable Securities at least fifteen
days before the anticipated filing date. Such notice shall offer such
Shareholders the opportunity to register such amount of Registrable Securities
as each such Shareholder may request (a "Piggyback Registration"). Subject to
Section 3(b) hereof, the Company shall include in each such Piggyback
Registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein. The Shareholders of Registrable
Securities shall be permitted to withdraw all or part of the Registrable
Securities from a Piggyback Registration at any time prior to the effective date
of such Piggyback Registration.

                          (b)  Priority on Piggyback Registrations. The Company
shall cause the managing underwriter of a proposed underwritten offering to
permit Shareholders of Registrable Securities requested to be included in the
registration for such offering to include all such Registrable Securities on the
same terms and conditions as any similar securities, if any, of the Company
included therein. Notwithstanding the foregoing, if the managing underwriter of
such offering delivers an opinion to the holders of Registrable Securities that
the total number or dollar amount of securities that such Shareholders, the
Company and any other Persons having rights to participate in


                                        4

<PAGE>   5

such registration ("Other Holders"), propose to include in such offering is such
as to materially and adversely affect the success of such offering, then:

                                  (i) if such Piggyback Registration is a
primary registration on behalf of the Company, the amount of securities to be
offered for the account of Shareholders of Registrable Securities and Other
Holders, shall be reduced (to zero if necessary) pro rata on the basis of the
number or dollar amounts of securities owned by each such holder participating
in such offering to the extent necessary to reduce the total amount of
securities to be included in such offering to the amount recommended by such
managing underwriter or underwriters; and

                                  (ii) if such Piggyback Registration is an
underwritten secondary registration on behalf of holders of securities of the
Company pursuant to demand registration rights, the Company shall include in
such registration: (x) first, up to the full number or dollar amount of
securities of such Persons exercising "demand" registration rights that in the
opinion of such managing underwriter or underwriters can be sold or allocated
among such holders as they may otherwise so determine, and (y) second, any
securities to be sold for the account of the Company and (z) third, the number
or dollar amount of Registrable Securities and securities held by Shareholders
and Other Holders in excess of the amount of securities such Persons exercising
"demand" registration rights propose to sell that, in the opinion of such
managing underwriter or underwriters, can be sold (allocated pro rata among the
Shareholders of such Registrable Securities and Other Holders on the basis of
the number or dollar amount of securities owned by such holders).

4.       Hold-Back Agreements

                          (a)  Restrictions on Sale by Shareholders of
Registrable Securities. Each Shareholder agrees not to effect any sale or
transfer of the Registrable Securities issued to it as part of the consideration
under the Note Purchase Agreement until the earlier to occur of (i) September
17, 1995, and (ii) the shareholder vote with respect to the Additional Issuance.
In addition, each Shareholder whose Registrable Securities are covered by a
Registration Statement filed pursuant to Section 2 or 3 hereof, agrees that, if
such Shareholder is requested (pursuant to a timely written notice) by the
managing underwriter in an underwritten offering, not to effect any public sale
or distribution of any of the Company's equity securities, including a sale
pursuant to Rule 144 (except as part of such underwritten registration), during
the 10-day period prior to, and during the 90-day period beginning on, the
closing date of each underwritten offering made pursuant to such Registration
Statement. If a request is made pursuant to this Section 4(a), the time period
during which a Shelf Registration is required to remain continu-


                                        5
<PAGE>   6

ously effective pursuant to Section 2(c) shall be extended by 100 days or such
shorter period that will terminate when all such Registrable Securities not so
included have been sold pursuant to such Registration Statement.

                          (b)  Restrictions on Sale by the Company and Others.
The Company shall not effect any registration of its securities (other than a
registration statement on Form S-8 or any successor form thereto), or effect any
public or private sale or distribution of any of its securities other than in
connection with the Additional Issuance, including a sale pursuant to Regulation
D under the Securities Act, whether on its own behalf or at the request of any
holder or holders of such securities (other than pursuant to and in accordance
with this Agreement), (i) from the date hereof until 90 days after the effective
date of the Shelf Registration, and (ii) for a 90 day period from the date of
each notice to the Company of a Shareholder's intent to sell Registrable
Securities pursuant to an underwritten public offering, unless the Company shall
have first notified in writing the Shareholders of Registrable Securities
covered by such Registration Statement of its intention to do so, and the
Shareholders of a majority of the Registrable Securities requested to be
registered pursuant to Section 2 shall have consented thereto in writing;
provided that the Company shall not be obligated to refrain from sales or
transfers pursuant to clause (ii) above with respect to more than one such
underwritten public offering during any 12-month period.

                 The Company shall cause each holder of its equity securities
purchased from the Company at any time on or after the date of this Agreement
(other than in a registered public offering) to agree not to effect any public
sale or distribution of any such securities during such period, including a sale
pursuant to Rule 144.

5.       Registration Procedures

                 In connection with the Company's registration obligations
pursuant to Sections 2 and 3 hereof, the Company shall effect such registrations
to permit the sale of such Registrable Securities in accordance with the
intended method or methods of disposition thereof, and pursuant thereto the
Company shall as expeditiously as possible:

                          (a)  Prepare and file with the SEC a Registration
Statement or Registration Statements on any appropriate Form under the
Securities Act available for the sale of the Registrable Securities by the
holders thereof in accordance with the intended method or methods of
distribution thereof, and cause each such Registration Statement to become
effective and remain effective as provided herein; provided, however, that
before filing a Registration Statement or Prospectus or any amendments or
supplements thereto (including documents that would be incorporated or deemed to


                                        6
<PAGE>   7

be incorporated therein by reference) the Company shall furnish to the
Shareholders of the Registrable Securities covered by such Registration
Statement, the Special Counsel and the managing underwriters, if any, copies of
all such documents proposed to be filed, which documents will be subject to the
review of such Shareholders, the Special Counsel and such underwriters, and the
Company shall not file any such Registration Statement or amendment thereto or
any Prospectus or any supplement thereto (including such documents which, upon
filing, would or would be incorporated or deemed to be incorporated by reference
therein) to which the Shareholders of a majority of the Registrable Securities
covered by such Registration Statement, the Special Counsel or the managing
underwriter, if any, shall reasonably object to the contents thereof on a timely
basis.

                          (b)  Prepare and file with the SEC such amendments and
post-effective amendments to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective for the applicable
period specified in Section 2; cause the related Prospectus to be supplemented
by any required Prospectus supplement, and as so supplemented to be filed
pursuant to Rule 424 (or any similar provisions then in force) under the
Securities Act; and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such Registration
Statement during the applicable period in accordance with the intended methods
of disposition by the sellers thereof set forth in such Registration Statement
as so amended or to such Prospectus as so supplemented.

                          (c)  Notify the selling Shareholders of Registrable
Securities, the Special Counsel and the managing underwriters, if any, promptly,
and (if requested by any such Person) confirm such notice in writing, (i) when a
Prospectus or any Prospectus supplement or post-effective amendment has been

purpose, (vi) of the happening of any event which makes any statement made in
such Registration Statement or related Prospectus or any document

incorporated or deemed to be incorporated therein by reference untrue or which
requires the making of any changes in a Registration Statement, Prospectus or
documents so that, in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading, and that in the case of the Prospectus, it will not contain any
untrue statement of a material fact required to be stated therein is necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading, and (vii) of the Company's reasonable determination
that a post-effective amendment to a Registration Statement would be

                          (d)  Use every reasonable effort to obtain the
withdrawal of any order suspending the effectiveness of a Registration
Statement, or the lifting of any suspension of the qualification (or exemption

by such Prospectus or any amendment or supplement thereto.

Registrable Securities, the underwriters, if any, and their respective counsel

amendment to each Registration Statement or a supplement to the related

an untrue statement of a material fact or omit to state a material fact required

the circumstances under which they were made, not misleading.

requested; (ii) obtain opinions of counsel to the Company and updates thereof
(which counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to the managing underwriters, if any, and the Shareholders of a
majority of the Registrable Securities being sold) addressed to each selling
Shareholder of Registrable Securities and each of the underwriters, if any,

<PAGE>   11

such selling Shareholders or underwriter, all financial and other records,
pertinent corporate documents and properties of the Company and its
subsidiaries, and cause the officers, directors and employees of the Company and
its subsidiaries to supply all information reasonably requested by any such
representative, underwriter, attorney or accountant in connection with such
Registration Statement; provided, however, that any records,

                          (n)  File any reports required to be filed by it under
the Securities Act and the Securities Exchange Act of 1934, as amended, and that
it will take such further action as any Shareholder may reasonably request, all
to the extent required from time to time to enable Shareholders to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 or Rule 144A under the
Securities Act, as such Rules may be amended from time to time, or (b) any
similar rule or regulation hereafter adopted by the SEC. Upon the request of any
Shareholder, the Company will deliver to such Shareholder a written statement as
to whether it has complied with such requirements.

                          (o)  Use its best efforts to comply with all 
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering a
period of 12 months, beginning within three months after the effective date of
the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act.

                          (p)  Prior to the effective date of the Shelf

                          (q)  In connection with an underwritten offering,

the offering or the Holders, in customary efforts to sell the securities under
the offering, including, without


                                       11
<PAGE>   12

limitation, participating in "road shows"; provided that the Company shall not
be obligated so to participate in more than one such offering in any 12-month
period.




                 The Company may require each seller of Registrable Securities
as to which any registration is being effected to furnish to the Company such
information regarding the distribution of such Registrable Securities as the
Company may, from time to time, reasonably request in writing.

                 Each Shareholder of Registrable Securities agrees by
acquisition of such Registrable Securities that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
5(c)(ii), 5(c)(iii), 5(c)(v), 5(c)(vi) or 5(c)(vii) hereof, such Shareholder
will forthwith discontinue disposition of such Registrable Securities covered by
such Registration Statement or Prospectus until such Shareholder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
5(j) hereof, or until it is advised in writing (the "Advice") by the Company
that the use of the applicable Prospectus may be resumed, and has received
copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such Prospectus. In the event the Company
shall give any such notice, the time period mentioned in Section 2(c) hereof
shall be extended by the number of days during the time period from and
including the date of the giving of such notice to and including the date when
each seller of Registrable Securities covered by such Registration Statement
shall have received (x) the copies of the supplemented or amended Prospectus
contemplated by Section 5(j) hereof or (y) the Advice.

6.       Registration Expenses

                          (a)  All fees and expenses incident to the performance
of or compliance with this Agreement by the Company shall be borne by the
Company whether or not any of the Registration Statements become effective. Such
fees and expenses shall include, without limitation, (i) all registration and
filing fees (including, without limitation, fees and expenses (x) with respect
to filings required to be made with the National Association of Securities
Dealers, Inc. and (y) of compliance with securities or "blue sky" laws
(including without limitation fees and disbursements of counsel for the
underwriters or selling holders in connection with "blue sky" qualifications of
the Registrable Securities and determination of the eligibility of the
Registrable Securities for investment under the laws of such jurisdictions as
the managing under-

                                       12
<PAGE>   13

writers, if any, or Shareholders of a majority of the Registrable Securities
being sold may designate)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities in a
form eligible for deposit with DTC and of printing prospectuses if the printing
of prospectuses is requested by the Shareholders of a majority of the
Registrable Securities included in any Registration Statement), (iii) messenger,
telephone and delivery expenses, (iv) fees and disbursements of counsel for the

accountants referred to in Section (5)(m)(iii) hereof (including the expenses of
any annual or special audit and "cold comfort" letters required by or incident

                          (b)  In connection with any Shelf Registration or
Piggyback Registration hereunder, the Company shall reimburse the Shareholders
of the Registrable Securities being registered in such registration for the
reasonable fees and disbursements of not more than one counsel (or more than one
counsel if a conflict exists among such selling Shareholders in the exercise of
the reasonable judgment of counsel for the selling Shareholders and counsel for
the Company), together with appropriate local counsel, chosen by the
Shareholders of a majority of the Registrable Securities being registered.

7.       Indemnification

                          (a)  Indemnification by the Company. The Company 
shall, without limitation as to time, indemnify and hold harmless, to the
fullest extent permitted by law, each Shareholder of Registrable Securities, the
partners, officers, directors, agents and employees of each of them, each Person
who controls such Shareholder (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) and the partners, officers,
directors, agents and employees of each such controlling person, from and
against all losses, claims, damages, liabilities, costs (including, without
limitation, the costs of preparation and attorneys' fees) and expenses
(collectively, "Losses") to be reimbursed promptly, as incurred, arising out of
or based upon any untrue or alleged untrue statement of a material fact
contained in any Registration Statement, Prospectus or form of Prospectus or in
any amendment or supplement thereto or in any preliminary prospectus, or arising
out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are based solely upon
information furnished in writing to the Company by such Shareholder expressly
for use therein. The Company shall also indemnify each underwriter, selling
broker, dealer manager and similar securities industry professional
participating in the distribution, and each of their officers, directors, agents
and employees and each Person


                                       13
<PAGE>   14

who controls such Persons (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) to the same extent as provided above with
respect to the indemnification of the holders of Registrable Securities.

                          (b)  Indemnification by Shareholder of Registrable
Securities. In connection with any Registration Statement in which a Shareholder
of Registrable Securities is participating, such Shareholder of Registrable
Securities shall furnish to the Company in writing such information as the
Company reasonably requests for use in connection with any Registration
Statement or Prospectus and agrees to indemnify, to the fullest extent permitted
by law, the Company, its directors and officers, agents and employees, each
Person who controls the Company (within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act), and the directors, officers,
agents or employees of such controlling persons, from and against all Losses
arising out of or based upon any untrue statement of a material fact contained
in any Registration Statement, Prospectus or preliminary prospectus or arising
out of or based upon any omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, to the
extent, but only to the extent, that such untrue statement or omission is
contained in and in conformity with any information so furnished in writing by
such Shareholder to the Company expressly for use in such Registration Statement
or Prospectus and that such information was solely relied upon by the Company in
preparation of such Registration Statement, Prospectus or preliminary
prospectus. In no event shall the liability of any selling Shareholder of
Registrable Securities hereunder be greater in amount than the dollar amount of
the proceeds (net of payment of all expenses) received by such Shareholder upon
the sale of the Registrable Securities giving rise to such indemnification
obligation.

                          (c)  Conduct of Indemnification Proceedings. If any
Person shall be entitled to indemnity hereunder (an "indemnified party"), such
indemnified party shall give prompt notice to the party from which such
indemnity is sought (the "indemnifying party") of any claim or of the
commencement of any Proceeding with respect to which such indemnified party
seeks indemnification or contribution pursuant hereto; provided, however, that
the failure to so notify the indemnifying party shall not relieve the
indemnifying party from any obligation or liability except to the extent that
the indemnifying party has been prejudiced materially by such failure. All such
fees and expenses (including any fees and expenses incurred in connection with
investigating or preparing to defend such action or proceeding) shall be paid to
the indemnified party, as incurred, within five days of written notice thereof
to the indemnifying party (regardless of whether it is ultimately determined
that an indemnified party is not entitled to indemnification hereunder). The
indemnifying party shall not consent to entry of any judgment or enter into any
settlement or otherwise seek to terminate any Proceeding in


                                       14
<PAGE>   15

which any indemnified party is or could be a party and as to which
indemnification or contribution could be sought by such indemnified party under
this Section 7, unless such judgment, settlement or other termination includes
as an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release, in form and substance satisfactory to the
indemnified party, from all liability in respect of such claim or litigation for
which such indemnified party would be entitled to indemnification hereunder.

                          (d)  Contribution. If the indemnification provided for
in this Section 7 is unavailable to an indemnified party under Section 7(a) or
7(b) hereof in respect of any Losses or is insufficient to hold such indemnified
party harmless, then each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall, jointly and severally, contribute to the amount
paid or payable by such indemnified party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party or indemnifying parties, on the one hand, and such indemnified party, on
the other hand, in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such indemnifying party or indemnifying parties, on the
one hand, and such indemnified party, on the other hand, shall be determined by
reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact or omission or alleged
omission of a material fact, has been taken or made by, or relates to
information supplied by, such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include any
legal or other fees or expenses incurred by such party in connection with any
Proceeding.

                 The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by
pro rata allocation or by any other method of allocation that
does not take into account the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provision of this Section
7(d), an indemnifying party that is a selling Shareholder of Registrable
Securities shall not be required to contribute any amount in excess of the
amount by which the total price at which the Registrable Securities sold by such
indemnifying party and distributed to the public were offered to the public
exceeds the amount of any damages which such indemnifying party has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section


                                       15
<PAGE>   16

11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

                 The indemnity, contribution and expense reimbursement
obligations of the Company hereunder shall be in addition to any liability the
Company may otherwise have hereunder or otherwise. The provisions of this
Section 7 shall survive so long as Registrable Securities remain outstanding,
notwithstanding any transfer of the Registrable Securities by any Shareholder or
any termination of this Agreement.

8.       Underwritten Registrations

                 If any of the Registrable Securities covered by a Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will manage the offering will
be selected by the Shareholders of a majority of such Registrable Securities
included in such offering. If any Piggyback Registration is an underwritten
offering, the Company shall have the right to select the investment banker or
investment bankers and managers to administer the offering; provided,
however, that such investment bank or manager shall be reasonably
satisfactory to the Shareholders of a majority of the Registrable Securities
included in such offering.

9.       Miscellaneous

                          (a) Remedies. In the event of a breach by the Company
of its obligations under this Agreement, each Shareholder of Registrable
Securities, in addition to being entitled to exercise all rights granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Agreement. The Company agrees that monetary damages would not
be adequate compensation for any loss incurred by reason of a breach by it of
any of the provisions of this Agreement and hereby further agrees that, in the
event of any action for specific performance in respect of such breach, it shall
waive the defense that a remedy at law would be adequate.

                          (b) No Inconsistent Agreements. The Company has not,
as of the date hereof, and shall not, on or after the date of this Agreement,
enter into any agreement with respect to its securities which is inconsistent
with the rights granted to the Shareholders of Registrable Securities in this
Agreement or otherwise conflicts with the provisions hereof. The Company has not
entered into any agreement with respect to its securities granting any
registration rights to any Person other than this Agreement.


                                       16

                          (c) Amendments and Waivers. This Agreement may be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may be given, provided the same are in writing and signed
by the Company and each of the Shareholders of Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Shareholders of Registrable Securities whose securities are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect the
rights of other Shareholders of Registrable Securities may, in lieu of complying
with the first sentence of this Section 9(c), be given by all Shareholders of
the Registrable Securities being sold; provided, however, that the provisions of
this sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

                          (d) Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing and shall be deemed

next-day courier, postage prepaid, to the parties as follows:

         the Company in accordance with the provisions of this Section 9(d),
         which address initially is the address set forth on its respective
         signature page attached hereto; and

                                  (y) if to the Company, initially at Four
         Embarcadero Center, Suite 3620, San Francisco, California 94111-4115,

         at such other address, notice of which is given in accordance with the
         provisions of this Section 9(d);

or to such other address as any party may have furnished to the other parties in
writing in accordance herewith.

                          (e) Owner of Registrable Securities. The Company will
maintain, or will cause its registrar and transfer agent to maintain, a stock
book with respect to the Common Stock and the Warrants, in which all transfers
of Registrable Securities of which the Company has received notice will be
recorded. The Company may deem and treat the person in whose name Registrable
Securities are registered in the stock book of the Company as the owner thereof
for all purposes, including without limitation, the giving of notices under this
Agreement.


                                       17
<PAGE>   18

                          (f) Successors and Assigns. This Agreement shall be
binding upon and shall inure to the benefit of any and all successors and
assigns of each of the parties and shall inure to the benefit of each
Shareholder of any Registrable Securities. The Company may not assign its rights
or obligations hereunder without the prior written consent of each Shareholder
of any Registrable Securities. Notwithstanding the foregoing, no transferee
shall have any of the rights granted under this Agreement (i) until such
transferee shall acknowledge its rights and obligations hereunder by a signed
written statement of such transferee's acceptance of such rights and obligations
or (ii) if the transferor notifies the Company in writing on or prior to such
transfer that the transferee shall not have such rights.

                          (g) Counterparts. This Agreement may be executed in
any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of

                                PROMISSORY NOTE

                                  May 17, 1995

Four Embarcadero Ctr. Suite 3620          San Francisco          CA 94111-4155


FOUR VALUE RECEIVED, American Shared Hospital Services ("Maker") promises, 
jointly and severally if more than one, to pay to the order of GENERAL ELECTRIC 
COMPANY or any subsequent holder hereof (each, a "Payee") at its office located 
at 20825 Swenson Drive, Waukesha, WI 53186 or at such other place as Payee may 
designate, the principal sum of One million five hundred thousand and 00/100 
($1,500,000.00), with interest on the unpaid principal balance from and 
including the date hereof at the rate of ten and 50/100 percent (10.50%) per 
annum, to be paid in lawful money of the United States, in 18 consecutive 
monthly installments of principal and interest of Ninety thousand four hundred 
thirty-one and 33/100 calculated in arrears ($90,431.33) and a final 
installment which shall be in the amount of the total outstanding principal and 
interest. The first installment shall be due and payable June 17, 1995 and the 
following installments shall be due and payable on the same day of each 
succeeding month (each, a "Payment Date").

All payments shall be applied first to interest and then to principal. The 
acceptance by Payee of any payment which is less than payment in full of all 
amounts due and owing at such time shall not constitute a waiver of Payee's 
right to receive payment in full at such time or at any prior or subsequent 
time. Interest shall be calculated on the basis of a 365 day year and will be 
charged for each calendar day on which any principal is outstanding.

The Maker hereby expressly authorizes General Electric Company to insert the 
date value is actually given in the blank space on the face hereof.

Time is of the essence hereof. If any installment of principal and interest or 
any other sum due under this Note is not received within ten (10) days after 
the applicable Payment Date, the Maker agrees to pay in addition to the amount 
of each such installment a late payment charge of five percent (5%) of said 
installment, but not exceeding any lawful maximum. In the event that (i) Maker 
fails to make payment of any amount due hereunder within ten (10) days after 
the same becomes due and payable; or (ii) Maker defaults or fails to perform 
under any term or condition contained in any other agreement with Payee, then 
the entire principal sum remaining unpaid, together with all interest thereon 
and any other sum payable under this Note, at the election of Payee, shall 
immediately become due and payable, with interest thereon at 20% per annum from 
the date of such accelerated maturity until paid.

The Maker may prepay in full, but not in part, its entire indebtedness 
hereunder upon payment of an additional sum as a premium equal to the following 
percentages of the original principal balance for the indicated period:

[Prior to the first annual anniversary date of this Note: five percent (5%)
Prior to the second annual anniversary date of this Note: four percent (4%)
Prior to the third annual anniversary date of this Note: three percent (3%)
Prior to the fourth annual anniversary date of this Note: two percent (2%)
Prior to the fifth annual anniversary date of this Note: one percent (1%)
and zero percent (0%) thereafter, plus all other sums due hereunder.]

Your default under a Schedule or default by you or any entity managed or 
controlled by you or by any principal of yours under any other agreement or 
contract with us, regardless of when the agreement or contract was entered 
into, will, at our sole option, if the default is not cured within ten days 
after written notice of default, constitute a default of that Schedule and all 
other agreements and contracts between you and/or such a principal or entity 
and us.

Language indicated as being shown by strike out in the typeset document is 
enclosed in brackets "[" and "]" in the electronic format.


                                       1

It is the intention of the parties hereto to comply with the 
applicable usury laws; accordingly, it is agreed that, 
notwithstanding any provision to the contrary in this Note, in no 
event shall this Note require the payment or permit the collection of 
interest in excess of the maximum amount permitted by applicable law. 
If any such excess interest is contracted for, charged or received 
under this Note, or in the event that all of the principal balance 
shall be prepaid, so that under any of such circumstances the amount 
of interest contracted for, charged or received under this Note on 
the principal balance shall exceed the maximum amount of interest 
permitted by applicable law, then in such event (a) the provisions 
of this paragraph shall govern and control, (b) neither Maker nor 
any other person or entity now or hereafter liable for the payment 
hereof shall be obligated to pay the amount of such interest to the 
extent that it is in excess of the maximum amount of interest 
permitted by applicable law, (c) any such excess which may have 
been collected shall be either applied as a credit against the then 
unpaid principal balance or refunded to Maker, at the option of the 
Payee, and (d) the effective rate of interest shall be 
automatically reduced to the maximum lawful contract rate allowed under 
applicable law as now or hereafter construed by the courts having jurisdiction 
thereof. It is further agreed that without limitation of the foregoing, all 
calculations of the rate of interest contracted for, charged or received under 
this Note which are made for the purpose of determining whether such rate 
exceeds the maximum lawful contract rate, shall be made, to the extent 
permitted by applicable law, by amortizing, prorating, allocating and spreading 
in equal parts during the period of the full stated term of the indebtedness 
evidenced hereby, all interest at any time contracted for, charged or received 
from Maker or otherwise by Payee in connection with such indebtedness; 
provided, however, that if any applicable state law is amended or the law of 
the United States of America preempts any applicable state law, so that it 
becomes lawful for the Payee to receive a greater simple interest per annum 
rate than is presently allowed, the Maker agrees that, on the effective date of 
such amendment or preemption, as the case may be, the lawful maximum hereunder 
shall be increased to the maximum simple interest per annum rate allowed by the 
higher of the amended state law or the law of the United States of America.

The Maker and all sureties, endorsers, guarantors or any others (each such 
person, other than the Maker, an "Obligor") who may at any time become liable 
for the payment hereof jointly and severally consent hereby to any and all 
extensions of time, renewals, waivers or modifications of, and all 
substitutions or releases of any party primarily or secondarily liable on this 
Note or any term and provision hereof, which may be made, granted or consented 
to by Payee, and agree that suit may be brought and maintained against any one 
or more of them, at the election of payee without joinder of any other as a 
party thereto. The Maker and each Obligor hereby waives presentment, demand for 
payment, notice of nonpayment, protest, notice of protest, notice of dishonor, 
and all other notices in connection herewith, as well as filing of suit (if 
permitted by law) and diligence in collecting this Note, and agrees to pay (if 
permitted by law) all expenses incurred in collection, including Payee's actual 
attorneys' fees. Maker and each Obligor agrees that fees not in excess of 
twenty percent (20%) of the amount then due shall be deemed reasonable. Maker 
and each Obligor hereby waives all benefits of valuation, appraisement and 
exemption laws.

                AMENDMENT TO PROMISSORY NOTE DATED MAY 17, 1995
                              CONTRACT 8508100-001

                            SAN FRANCISCO, CA 94111


This is an Amendment to Promissory Note ("Note") (contract 8508100) from 
AMERICAN SHARED HOSPITAL SERVICES ("ASHS") in favor of GENERAL ELECTRIC COMPANY 
("GE") dated May 17, 1995. The Note was for $1,500,00.00 and was collateralized 
by the Gamma Knife at UCSF. The Note commenced billing June 17, 1995 (in 
arrears) for eighteen (18) months.

It is agreed and understood that ASHS has obtained an extension to its contract 
with UCSF to provide the Gamma Knife on a per procedure basis. The contract 
between ASHS and UCSF will now run through September 17, 1998. In consideration 
of this contract extension, GE is extending the terms of its Note with ASHS 
effective September 17, 1995 and lowering the monthly payment. A new 
amortization schedule is attached as Exhibit A.

All other Terms and Conditions from the original Note, to the extent not 
inconsistent herewith, shall remain as initially written and apply to this
Amendment.

                 FOR VALUE RECEIVED, the undersigned AMERICAN SHARED-CURACARE 
and CURACARE, INC. (collectively and individually "Maker") jointly and severally
hereby promise to pay to DVI BUSINESS CREDIT CORPORATION or its assignee (the
"Holder), or order, the principal sum of Four Million and No/100 Dollars
($4,000,000) or such amount thereof as may be from time to time advanced
hereunder, pursuant to the terms of that certain Loan and Security Agreement
dated as of the date hereof between Holder as Lender, Maker as Borrower,
American Shared Hospital Services as Guarantor and Ernest A. Bates, M.D. as
Individual Guarantor (the "Agreement"), with interest on the unpaid principal
balance from time to time outstanding until paid at the fluctuating rate of
interest announced publicly by Bank of America, NT&SA in San Francisco,
California, from time to time as its base rate plus Five percent (5.0%) per
annum, computed on the basis of a 360-day year and actual days elapsed, until
paid. Interest shall be payable at the end of each month this Note is
outstanding in accordance with the terms of the Agreement, with all unpaid
principal and interest due and payable in full on May 31, 1997.

                 If any part of the interest due on this Note is not paid when
due, it shall be added to the principal amount of this Note and thereafter bear
interest at the rate provided above. If the specified interest rate shall at any
time exceed the maximum allowed by law, then the applicable interest rate shall
be reduced to the maximum allowed by law.

                 1. This Note shall be subject to prepayment or redemption in
whole or in part at any time without penalty or premium. Notwithstanding the
foregoing, the Agreement may not be terminated, and will not be terminated by
any prepayment, without payment of the termination fee required pursuant to
Section 2.7 of the Agreement.

                 2. Principal and interest shall be payable to Holder at 4041
MacArthur Avenue, Suite 401, Newport Beach, California 92660, or such other
place as the Holder may, from time to time in writing, appoint.

                 3. This Note is made pursuant to, and secured by the Agreement.
This Note is also secured by any Security Documents referred to in the
Agreement. The Agreement and the Security Documents create a lien on and
security interest in, the personal property described therein
("Collateral"). The Agreement and the Security Documents shall
hereinafter be collectively referred to as the "Loan and Security
Documents" and are hereby incorporated by reference in and made a part of
this Note.

                 4. The occurrence of any Event of Default under the Agreement
shall, at the election of the Holder, make the entire unpaid balance of the
principal amount of this Note and accrued interest immediately due and payable
without notice of default, presentment or demand for payment, protest or notice
of nonpayment or dishonor, or other notices or demands of any kind or character.

                 5. Failure of the Holder to exercise the acceleration option of
paragraph 4 of this Note on the occurrence of any of the events enumerated
therein shall not constitute waiver of the right to exercise such option on the
subsequent occurrence of any of the events enumerated therein.

                 6. Principal and interest shall be payable in lawful money of
the United States of America which shall be legal tender in payment of all debts
and dues, public and private, at the time of payment. Maker waives presentment,
demand for payment, notice of nonpayment, protest and notice of protest, and all
other notices and demands in connection with the delivery, acceptance,
performance, default or enforcement of this Note. Maker consents to any and all
assignments of this Note, extensions of time, renewals and waivers that may be
made or granted by the Holder. Maker expressly agrees that such assignments,
extensions of time, renewals or waivers shall not affect Maker's liability.
Maker agrees that Holder may, without notice to Maker and without affecting the
liability of Maker, accept additional or substitute security for this Note,
release any security or any party liable for this Note or extend or renew this
Note.

                 7. If Maker shall fail to make any payment of interest or
principal, including the payment due upon maturity, when the same is due and
payable and such failure shall continue for five (5) business days after
nonpayment, a late charge by way of damages shall be immediately due and
payable. Maker recognizes that default by Maker in making the payments herein
agreed to be paid when due will result in the Holder incurring additional
expenses, in loss to the Holder of the use of the money due and in frustration
to the Holder in meeting its other commitments. Maker agrees that, if for any
reason Maker fails to pay any amount due under this Note when due, the Holder
shall be entitled to damages for the detriment caused thereby, but that it is
extremely difficult and impractical to ascertain the extent of such damages.
Maker therefore agrees that a sum equal to ten cents ($.10) for each one dollar
($1.00) of each payment which is not received within five (5) business days
after the date it is due and payable is a reasonable estimate of the said
damages to the Holder, which sum Maker agrees to pay on demand.

                 8. If action be instituted on this Note (including without
limitation, any proceedings for collection hereof in any bankruptcy or probate
matter or case), or if proceedings are commenced on or under any of the Loan and
Security Documents, Maker promises to pay the Holder all costs of collection and
enforcement including, without limitation, reasonable attorneys' fees.

                 9. Any and all notices or other communications or payments
required or permitted to be given hereunder shall be effective when received or
refused if given or rendered in writing, in the manner provided in the
Agreement.

                 10. This Note shall inure to the benefit of the Holder's
successors and assigns. References to the "Holder" shall be deemed to refer to
the holder(s) of this Note at the time such reference becomes relevant.

                 11. If any term, provision, covenant, or condition of this Note
is held by a court of competent jurisdiction to be invalid, void, or
unenforceable, the rest of this Note shall remain in full force and effect to
the greatest extent permitted by law and shall in no other way be affected,
impaired or invalidated.

                 12. Nothing contained herein or in the Loan and Security
Documents shall be deemed to prevent recourse to and the enforcement against
Maker and the Collateral of all liabilities, obligations and undertakings
contained herein and in the Loan and Security Documents.

                 13. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS
OF THE STATE OF CALIFORNIA AND MAKER AGREES TO SUBMIT TO THE JURISDICTION OF THE
STATE AND/OR FEDERAL COURTS IN THE STATE OF CALIFORNIA.

                                Due June 1, 1999

                 FOR VALUE RECEIVED, the undersigned AMERICAN SHARED-CURACARE
AND CURACARE, INC. (collectively and individually "Maker") hereby promise to pay

payable in full on June 1, 1999.

                 If any part of the principal or interest of this Note is not
paid when due, it shall thereafter bear interest a rate equal to the "Prime
Rate" announced by National Westminster Bank, USA (which is not necessarily the
best rate charged to its customers) plus two percent (2%) from and as of the

                 2. Principal and interest shall be payable to Holder at 500

without notice of default, presentment or demand for payment, protest or notice

of the right to exercise such option on the subsequent occurrence of any of the
events enumerated therein.

                 6. Principal and interest shall be payable in lawful money of

Obligor in favor of GE prior to the date hereof or pursuant to this Security
Agreement.

                 (d) Upon GE taking all actions required under each applicable
Code to perfect the security interest granted hereunder, this Security Agreement
creates a valid and perfected first priority security interest in and Lien on
all right, title and interest of Obligor in the Collateral, securing payment of
the Obligations prior to all other liens, encumbrances, security interests and
rights of others created under the UCC in the Collateral and is or will be, as
applicable, enforceable as such as against creditors of and purchasers from
Obligor to the extent provided in the Code. Obligor hereby warrants that, except
for such actions required under the applicable Code to be taken by GE in order
to perfect its security interest granted pursuant to this Security Agreement,
all filings and other actions necessary or desirable to protect and perfect such
lien and security interest in the Collateral have been duly made or taken.

         5. Covenants. Unless GE otherwise consents in writing, Obligor, with
respect to itself and the Collateral, hereby covenants and agrees with GE,
subject to the rights of the holders of the Permitted Liens, that from and after
the date of this Security Agreement and until the Obligations are fully
satisfied:

                 (a) At any time and from time to time, upon the written request
of GE, and at the sole expense of Obligor, Obligor will promptly and duly
execute and deliver any and all such further instruments and documents and take
such further action that may be necessary or desirable or that GE may reasonably
request in order to perfect and protect the security interest granted or
purported to be granted hereby or to enable GE to exercise and enforce its
rights and remedies hereunder with respect to the Collateral. Upon the written
request of GE, Obligor will execute and file such financing or continuation
statements, or amendments thereto, and such other instruments or notices, as may
be necessary or desirable, or as GE may reasonably request, in order to perfect
and preserve the security interests granted or purported to be granted hereby.

                 (b) Obligor hereby authorizes GE to file one or more financing
or continuation statements, and amendments thereto, relative to all or any part
of the Collateral without the signature of Obligor where permitted by law.

                 (c) Obligor will perform and comply in all material respects
with all obligations under contracts and all other agreements to which it is a
party or by which it is bound relating to the Collateral, the nonperformance of
which would have a Material Adverse Effect on Obligor.

                 (d) Other than Permitted Liens, Obligor will not create, permit
or suffer to exist, and Obligor will defend the Collateral against and take such
other action as is necessary to remove, any lien, security interest,
encumbrance, claim or right, in or to the Collateral; and Obligor will defend
the right, title and interest of GE in and to any of Obligor's rights to the
Collateral, including, without limitation, in and to the Proceeds and products
thereof against the claims and demands of all Persons whomsoever.

                 (e) Obligor shall not sell, transfer, assign (by operation of
law or otherwise), lease or otherwise dispose of or transfer any Collateral or
any interest therein, or attempt, offer or contract to do so.

                 (f) Obligor shall not enter into any transaction that is
reasonably likely to have a Material Adverse Effect on the Collateral.

                 (g) Obligor will advise GE promptly, in reasonable detail, of
(i) any lien, security interest, encumbrance or claim made or asserted against
any of the Collateral, other than the Permitted Liens, (ii) any material change
in the Collateral, and (iii) the occurrence of any other event which would be
reasonably likely to have a Material Adverse Effect on the aggregate value of
the Collateral or on the security interest created hereunder.

                 (h) GE shall at all times have full and free access during
normal business hours to all the books, correspondence and records of Obligor,
and GE or its representatives may examine the same, take extracts therefrom and
make photocopies thereof, and Obligor agrees to render to GE, at Obligor's sole
cost and expense, such clerical and other assistance as may be reasonably
requested with regard thereto. GE and its representatives shall at all times
also have the right to enter into and upon any premises where the Collateral is
located for the purpose of inspecting the same, or protecting its interests
therein.

                 (i) Obligor shall not change its corporate name without giving
GE at least thirty (30) days prior written notice of its intent to do so.

         6.      GE's Appointment as Attorney-in-Fact.

                 (a) Obligor hereby irrevocably constitutes and appoints GE and
any officer or agent thereof, with full power of substitution, as its true and
lawful attorney-in-fact with full irrevocable power and authority in the place
and stead of Obligor and in the name of Obligor or in GE's own name, from time
to time in GE's discretion, for the purpose of carrying out the terms of this
Security Agreement, to take any and all appropriate action and to execute any
and all documents and instruments which may be necessary or desirable to
accomplish the purposes of this Security Agreement and, without limiting the
generality of the foregoing, Obligor hereby gives GE the power and right, on
behalf of Obligor, without prior notice to or the consent of Obligor, to do the
following after the occurrence and during the continuance of an Event of
Default, subject, however, to the rights of the holders of the Permitted Liens:

                          (i) in the name of Obligor or in GE's own name or
otherwise, to take possession of and endorse and collect any checks, drafts,
notes, acceptances or other instruments for the payment of monies due with
respect to the Collateral;

                          (ii) to enforce the rights of GE with respect to the
Collateral;

                          (iii) to defend any suit, action or proceeding brought
with respect to the Collateral;

                          (iv) to settle, compromise or adjust any suit, action
or proceedings described above and, in connection therewith, to give such
discharges or releases as GE may deem appropriate;

                          (v) in connection with the dispositions provided in
Section 8 below, to sell, transfer, pledge, make any agreement with respect to
or otherwise deal with the Collateral as fully and completely as though GE were
the absolute owner thereof for all purposes; and

                                       -5-


<PAGE>   7



                          (vi) to do, at GE's option and Obligor's sole expense,
at any time, or from time to time, all acts and things which GE deems necessary
to protect, preserve or realize upon the Collateral and GE's security interest
therein, in order to effect the intent of this Security Agreement, all as fully
and effectively as Obligor might do.

                          Obligor hereby ratifies all that said attorney-in-fact
shall lawfully do or cause to be done by virtue hereof. This power of attorney
is a power coupled with an interest and shall be irrevocable.

                 (b) If Obligor fails to perform any agreement contained herein,
GE may itself perform, or cause performance of, such agreement.

                 (c) The powers conferred on GE hereunder are solely to protect
its interests in the Collateral and shall not impose any duty upon it to
exercise any such powers. GE shall be accountable only for amounts that it
actually receives as a result of the exercise of such powers, and neither it nor
any of its officers, directors, employees or agents shall be responsible to
Obligor for any act or failure to act, except for its own gross negligence or
willful misconduct.

         7.      Term; Performance by GE of Obligor's Obligations.

                 (a) This Security Agreement shall remain in full force and
effect until the payment and satisfaction in full of the Obligations.

                 (b) If Obligor fails to perform or comply with any of its
agreements contained herein and GE, as provided by the terms of this Security
Agreement, shall itself perform or comply, or otherwise cause performance or
compliance, with such agreement, the expenses of GE incurred in connection with
such performance or compliance, together with interest thereon at four percent
(4%) per annum shall be payable by Obligor to GE on demand and shall constitute
additional Obligations secured hereby.

         8.      Remedies, Rights Upon Default.  Upon and after an Event of 
Default:

                 (a) GE may, subject to the rights of the holders of the
Permitted Liens, exercise, in addition to all other rights and remedies granted
to it in this Security Agreement and in any other instrument or agreement
securing, evidencing or relating to the Obligations, all rights and remedies of
a secured party or lien creditor under the Code (whether or not the Code applies
to the affected Collateral) or under any other applicable law of any
jurisdiction. Without limiting the generality of the foregoing, Obligor
expressly agrees that in any such event GE shall have the right, subject,
however, to the rights of the holders of the Permitted Liens to (i) enter upon
the premises of Obligor, or any

                                       -6-


<PAGE>   8



other place where the Collateral is located and kept, through self-help and
without judicial process, without first obtaining a final judgment or giving
Obligor notice and opportunity for a hearing on the validity of GE's claim and
without any obligation to pay rent to Obligor, and to remove the Collateral
and/or (ii) to require Obligor to assemble, and Obligor hereby agrees to
assemble, the Collateral and make it available to GE at a place to be designated
by GE, in its sole discretion. GE, without demand of performance or other
demand, advertisement or notice of any kind (except the notice specified below
of the time and place of public or private sale) to or upon Obligor or any other
Person (all and each of which demands, advertisements and/or notices are hereby
expressly waived), may, subject to the rights of the holders of the Permitted
Liens, forthwith receive, appropriate and realize upon the Collateral, or any
part thereof and/or may forthwith sell, assign, give an option or options to
purchase, or otherwise dispose of and deliver said Collateral (or contract to do
so), or any part thereof, at public or private sale or sales board or at any of
GE's offices or elsewhere at such prices as it may deem best, for cash or on
credit without assumption of any credit risk. Any such sales may be adjourned
from time to time with or without notice. GE shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. GE shall have
the right upon any such public sale or sales, and, to the extent permitted by
law, upon any such private sale or sales, to purchase the whole or any part of
said Collateral so sold, free of any right or equity of redemption of Obligor
released and, in lieu of actual payment of the purchase price therefor, to set
off the amount of such purchase price against the Obligations. The net proceeds
of any such collection, recovery, receipt, appropriation, realization or sale,
after deducting all reasonable costs and expenses of every kind incurred therein
or incidental to the care, safekeeping or otherwise of any or all of the
Collateral or in any way relating to the rights of GE hereunder, including
reasonable attorneys' fees and legal expenses, shall be applied by GE to the
payment in whole or in part of the Obligations, in such order as GE may elect.
Obligor shall remain liable for any deficiency remaining unpaid after such
application, and only after (i) so paying over such net proceeds and after the
payment by GE of any other amount required by any provision of law, including
the Code, and (ii) paying to DVI any surplus amounts held by GE which DVI has
advised GE are payable to DVI, need GE account for the surplus, if any, to
Obligor. To the extent permitted by applicable law, Obligor waives all claims,
damages and demands against GE arising out of the repossession, retention or
sale of the Collateral. Obligor agrees that GE need not give more than ten (10)
days' notice of the time and place of any public sale or of the time after which
a private sale may take place and that such notice is reasonable notification of
such matters. Obligor shall remain liable for any deficiency if the proceeds of
any sale or disposition of the Collateral are insufficient to pay all amounts to
which GE is entitled, Obligor also being liable for the

                                       -7-


<PAGE>   9



reasonable fees and expenses of any attorneys employed by GE to collect such
deficiency.

                 (b) Except as otherwise provided in the Agreement and this
Security Agreement, Obligor hereby waives presentment, demand, protest or any
notice (to the extent permitted by applicable law) of any kind in connection
with this Security Agreement or any Collateral.

         9. Limitation on GE's Duty in Respect of Collateral. Beyond the safe
custody thereof, GE shall not have any duty as to any Collateral in its
possession or control or in the possession or control of any agent or nominee of
it or any income thereon or as to the preservation of rights against prior
parties or any other rights pertaining thereto.

         10. Attorneys' Fees and Expenses. If, during the existence and
continuance of an Event of Default, GE employs legal counsel or any other third
person for advice, consultation or other representation or incurs legal and/or
other costs and expenses in connection with: (a) the administration of this
Security Agreement or the Note and the transactions contemplated hereby and
thereby; (b) the custody, preservation, use or operation of, or the sale of,
collection from, or other realization upon, any of the Collateral, (c) the
exercise or enforcement of any of the rights of GE hereunder, (d) the failure by
Obligor to perform or observe any of the provisions hereof, or (e) any
litigation, contest, dispute, suit, proceeding or action (whether instituted by
GE, Obligor or any other Person) in any way relating to the Collateral, this
Security Agreement or the Note or Obligor's affairs; (f) any attempt to collect
any of the amounts under the Note or to enforce any rights of GE against Obligor
or any other Person which may be obligated to GE by virtue of this Security
Agreement or the Note; and/or (g) any attempt to inspect, verify, protect,
collect, sell, liquidate or otherwise dispose of the Collateral; then, in any
such event, the reasonable attorneys' fees arising from such services and all
reasonably incurred expenses, costs, charges and other fees of such counsel or
third party or of GE or relating to any of the events or actions described in
this Section 10 shall be payable, on demand, by Obligor to GE and shall be
additional Obligations secured by the Collateral.

         11. Waivers by Obligor. Except as otherwise provided for in the
Agreement and in this Security Agreement, Obligor hereby waives to the extent
allowed by law (a) presentment, demand and protest and notice of presentment,
protest, default, nonpayment, maturity, release, compromise, settlement,
extension or renewal of any or all commercial paper, documents, instruments and
guaranties at any time held by GE on which Obligor may in any way be liable and
hereby ratifies and confirms whatever GE may do in this regard; (b) notice prior
to taking possession or control of the Collateral or any bond or security which
might be required by any court prior to allowing GE to exercise any of GE's
remedies;

                                       -8-


<PAGE>   10



and (c) the benefit of all valuation, appraisement and exemption laws.

         12. Indemnity.

             (a) Obligor shall indemnify GE and its affiliates from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever (including, without limitation, fees and disbursements of counsel)
which may be imposed on, incurred by, or asserted against GE in any litigation,
proceeding or investigation instituted or conducted by any governmental agency
or instrumentality or any other Person with respect to any aspect of, or any
transaction contemplated by, or referred to in, or any matter related to, this
Security Agreement or the Note, except to the extent that any of the foregoing
arises out of the gross negligence or wilful misconduct of GE.

             (b) Obligor shall upon demand pay to GE the amount of any and all
reasonable expenses which GE may incur in connection with (i) the administration
of this Security Agreement, (ii) the custody, preservation, use or operation of,
or the sale of, collection from, or other realization upon, any of the
Collateral, (iii) the exercise or enforcement of any of the rights of GE
hereunder, or (iv) the failure by Obligor to perform or observe any of the
provisions hereof.

         13. Termination Statements. Obligor acknowledges and agrees that it is
Obligor's intent that all financing statements filed hereunder shall remain in
full force and effect until this Security Agreement and the Note shall have been
terminated in accordance with the provisions hereunder and thereunder.
Accordingly, Obligor waives any rights which it may have under the Code to
demand the filing of termination statements with respect to the Collateral, and
agrees that GE shall not be required to send such termination statements to
Obligor, or to file them with any filing office, unless and until this Security
Agreement and the Note shall have been terminated in accordance with their
respective terms as a result of the performance of all covenants of Obligor,
including the payment in full of all Obligations in immediately available funds.

         14. Notices. All notices and other communications under this Security
Agreement shall be given to GE and Obligor in accordance with Section 8.11 of
the Agreement.

         15. Severability. Any provision of this Security Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         16. No Waiver; Cumulative Remedies. GE shall not by any act, delay,
omission or otherwise be deemed to have waived any of its rights or remedies
hereunder, and no waiver shall be valid unless in writing, signed by GE, and
then only to the extent therein set forth. A waiver by GE of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or
remedy which GE would otherwise have had on any future occasion. No failure to
exercise nor any delay in exercising on the part of GE, any right, power or
privilege hereunder, shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies hereunder provided are cumulative and may be
exercised singly or concurrently, and are not exclusive of any rights and
remedies provided by law. None of the terms or provisions of this Security
Agreement may be waived, altered, modified or amended except by an instrument in
writing, duly executed by GE.

         17. Successors and Assigns; Governing Law. This Security Agreement and
all obligations of Obligor hereunder shall be binding upon the successors and
assigns of Obligor, and shall, together with the rights and remedies of GE
hereunder, inure to the benefit of GE and its successors and assigns. This
Security Agreement shall be governed by, and be construed and interpreted in
accordance with, the laws of the State of California, without giving effect to
any choice of law or conflict of law provision or rule (whether the State of
California or any other jurisdiction) that would cause the application of the
laws of any jurisdiction other than the State of California.

         18. No Third-Party Beneficiary. None of the provisions herein contained
are intended by the parties, nor shall they be deemed, to confer any benefit on
any person not a party to this Security Agreement.

         IN WITNESS WHEREOF, the parties have caused this Security Agreement to
the executed by their duly authorized officers on the date first specified
above.

                               AGREEMENT AND PROXY

                 This AGREEMENT AND PROXY (the "Agreement"), dated as of May 12,
1995, is made by Ernest A. Bates, M.D. ("Dr. Bates"), in order to induce ANCHOR
NATIONAL LIFE INSURANCE COMPANY, a California corporation, SUN LIFE INSURANCE
COMPANY OF AMERICA, an Arizona corporation, and SUNAMERICA INC., a Maryland
corporation (collectively, "SunAmerica"), AIF II, L.P., a Delaware limited
partnership, LION ADVISORS, L.P., a Delaware limited partnership, on behalf of
an account under management (together with AIF II, L.P., "Apollo"), GRACE
BROTHERS, LTD., an Illinois limited partnership, and UPCHURCH LIVING TRUST U/A/D
12/14/90 (each a "Holder," and collectively the "Holders") to enter into the
Note Purchase Agreement, dated the date hereof (the "Note Purchase Agreement").

                 NOW THEREFORE, Dr. Bates hereby agrees as follows:

                 1. Dr. Bates shall (a) not revoke any proxy granted by him or
on his behalf in connection with the April 7, 1995 shareholders meeting of
American Shared Hospital Services, a California corporation (the "Company") or
any adjournments thereof; and (b) cause the Company to reconvene the April 7,
1995 shareholders meeting on May 18, 1995 and to take the shareholders vote and
all related actions at such meeting with respect to the matters described in the
Company's Proxy Statement dated February 14, 1995 (the "Matters") on such date.

                 2. Dr. Bates hereby represents that he is the legal and
beneficial owner of 1,005,000 shares of Common Stock, no par value (the "Common
Stock"), of the Company and he hereby irrevocably appoints and constitutes
Apollo Advisors, L.P. and SunAmerica Inc., jointly and not severally, in
accordance with the provisions of Section 705 of the California General
Corporation Law, as his attorney and proxy, with full power of substitution, to
attend meetings, vote, give consents and to otherwise act on his behalf to (a)
cause the Company to reconvene the April 7, 1995 shareholders meeting (including
all adjournments thereof) and take the shareholders vote with respect to all
Matters, and (b) vote such shares with respect to all Matters; provided,
that this proxy shall (i) not become effective until the first to occur of a
default or other breach (x) by Dr. Bates of any provision hereof, or (y) by the
Corporation of the penultimate paragraph of the Letter Agreement, dated May 5,
1995, among the Company, Apollo and SunAmerica, and (ii) terminate (x)
immediately if it is used for any purpose other than as specified herein or (y)
on May 25, 1995 if the transactions contemplated by the Exchange Agreement,
dated February 14, 1995, as amended by the Note Purchase Agreement (the
"Exchange Agreement") have not been consummated by such date.


<PAGE>   2



                 3. Dr. Bates hereby represents that (a) this Agreement is a
valid and binding obligation of Dr. Bates enforceable in accordance with its
terms, except to the extent that such enforcement may be limited by bankruptcy,
insolvency, reorganization, moratorium, or other similar laws affecting
enforcement of creditor's rights generally, and by general principles of equity
(regardless of whether enforcement is considered in a proceeding at law or in
equity) and (b) the proxy granted herein is given in consideration of the
continuation of credit to the Company by the Holders.

                 4. Dr. Bates shall use all reasonable efforts to obtain all
consents and approvals, and to do all other things, necessary for the
transactions contemplated by this Agreement and the Note Purchase Agreement and
to take such further action and to deliver or cause to be delivered to each
other at the closing and at such other times thereafter as shall be reasonably
agreed by such additional agreements or instruments as any of them may
reasonably request for the purpose of carrying out this Agreement and the
agreements and transactions contemplated hereby.

                 5. Dr. Bates hereby acknowledges and agrees that irreparable
harm, for which there may be no adequate remedy at law and for which the
ascertainment of damages would be difficult, would occur in the event any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. Consequently, Dr. Bates hereby agrees
that each Holder shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically the
terms and provisions hereof in any court of the United States or any state
thereof having jurisdiction, in each instance without being required to post
bond or other security and in addition to, and without having to prove the
inadequacy of, other remedies at law.

                 6. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA, AS APPLIED TO CONTRACTS
MADE AND PERFORMED WITHIN THE STATE OF CALIFORNIA, WITHOUT REGARD TO PRINCIPLES
OF CONFLICT OF LAWS.

                 IN WITNESS WHEREOF, the undersigned has caused this Agreement
to be duly executed and delivered as of the date first above written. By their
acceptance hereof, the Holders hereby agree that the exercise of the proxy
granted to them by Dr. Bates pursuant to Section 2 hereof shall constitute their
agreement to waive any then remaining conditions to the Holders' performance
under the Exchange Agreement so long as the transactions contemplated by the
Exchange Agreement are consummated on or before May 25, 1995.

                          (b) Section 1(b) of the Exchange Agreement is hereby
amended in its entirety by substituting therefore the following:

                          "(b) The Company hereby agrees to cause all of the
         Notes tendered into the Exchange Offer to be returned to the respective

                                   Each of the Company and Dr. Bates hereby 
                 acknowledges and agrees that irreparable harm, for which there
                 may be no adequate remedy at law and for which the
                 ascertainment of damages would be difficult, would occur in the
                 event any of the provisions of this Agreement or any of the
                 Documents or any of the Restructuring Transactions were not
                 performed in accordance with their specific terms or were
                 otherwise breached. Consequently, each of the Company and Dr.
                 Bates hereby agrees that each Holder shall be entitled to an
                 injunction or injunctions to prevent breaches of the provisions
                 of this Agreement or any other Document or any of the
                 Restructuring Transactions and to enforce specifically the
                 terms and provisions hereof or thereof in any court of the
                 United States or any state thereof having jurisdiction, in each
                 instance without being required to post bond or other security
                 and in addition to, and without having to prove the inadequacy
                 of, other remedies at law."

                             (e) Section 6.1(d) of the Exchange Agreement is
hereby amended in its entirety by substituting therefore the following:

                             "(d) automatically on the earlier of (i) the
closing of the purchase of the Notes held by each Holder pursuant to the Note
Purchase Agreement, dated as of May 12, 1995, by and among the parties hereto
and (ii) May 25, 1995 or such earlier date on or after May 15, 1995 designated
by Apollo and SunAmerica in a written notice to the Company."

                             (f) Except as expressly set forth herein, all terms
and conditions of the Exchange Agreement shall remain unaffected. All references
to the term "Agreement" therein shall be deemed to refer to the Exchange
Agreement as modified hereby.

subsidiaries of the Documents to which it is a party, the performance by each of
the Company and each of its subsidiaries of its obligations under this Agreement

Adverse Effect on the Company after the date on which the transactions
contemplated hereby or thereby are consummated, or (ii) except as set forth in
the Proxy Statement on the date hereof, result in the imposition of any penalty

(i) for which consents have already been obtained; and (ii) which could not,
singly or in the aggregate, have a Material Adverse Effect on the Company.

                 The execution and delivery of this Agreement and the

respective stockholders or affiliates are necessary to authorize this Agreement
or to consummate the Note Purchase. This Agreement is a valid and binding
obligation of such Holder, enforceable in accordance with its terms, except to
the extent that enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws
affecting enforcement of creditor's rights generally, and by general principles
of equity (regardless of whether enforcement is considered in a proceeding at
law or in equity).

                            (a) Such Holder understands that the Note Purchase
is intended to be exempt from registration under the Securities Act of 1933, as
amended (the "Securities Act").

                            (b) The shares of Common Stock and Warrants
(including the Delayed Securities, if any) to be acquired by such Holder in the

any state securities laws which may be applicable.

                            (c) Such Holder has sufficient knowledge and
experience in financial and business matters so as to be capable of evaluating
the merits and risks of its investment in such shares of Common Stock and
Warrants (including the Delayed Securities, if any) and such Holder is capable
of bearing the economic risks of such investment, including a complete loss of
its investment.

                            (d) Such Holder is an "accredited investor" as such
term is defined in Regulation D under the Securities Act.

the shares of Common Stock and Warrants being acquired by it (including the
Delayed Securities, if any) shall bear a legend substantially in the form of
Schedule B hereto.

                            (b) that the exercise of the proxy granted by Dr.
Bates pursuant to that certain Agreement and Proxy, dated as of the date hereof,

obtain all consents and approvals, and to do all other things, necessary for the
transactions contemplated by this Agreement on or prior to the termination of
this Agreement pursuant to Section 7.1 hereof. The parties agree to take such
further action and to deliver or cause to be delivered to each other at the
closing and at such other times thereafter as shall be reasonably agreed by such
additional agreements or instruments as any of them may reasonably request for

SECTION 7.                Miscellaneous

          Section 7.1       Termination

                 This Agreement may be terminated and the Note Purchase may be

respect (other than those qualified by a materiality standard which shall have
been breached in any respect); or (ii) the Company's board of directors fails to

                 This Agreement shall be binding upon and shall inure to the
benefit of any and all successors and assigns of the parties hereto. This
Agreement may not be assigned by any party, by operation of law or otherwise,
without the express prior written consent of each of the other parties, which
consent may be granted or withheld in each such party's sole discretion;

          Section 7.3              Specific Performance

                 Each of the Company and Dr. Bates and, with respect to Section
6.3, the Holders hereby acknowledges and agrees that irreparable harm, for which
there may be no adequate remedy at law and for which the ascertainment of
damages would be difficult, would occur in the event any of the provisions of
this Agreement or any of the Documents or any of the Purchase Transactions were
not performed in accordance with their specific terms or were otherwise
breached. Consequently, each of the Company and Dr. Bates and, with respect to
Section 6.3, the Holders hereby agrees that each party hereto shall be entitled
to an injunction or injunctions to prevent breaches of the provisions of this
Agreement or any other Document or any of the Purchase Transactions and to
enforce specifically the terms and provisions hereof or thereof in any court of
the United States or any state thereof having jurisdiction, in each instance
without being required to post bond or other security and in addition to, and
without having to prove the inadequacy of, other remedies at law.

                  SECTION 1.3. CONSTRUCTION.

                  (a) Unless the context of this Agreement clearly requires

calculated on a daily basis on the reports delivered to Lender pursuant to
Section 5.4.

                  SECTION 2.2. REVOLVING NATURE OF THE LOAN. On a daily basis
the Borrowing Base will be recalculated by adding daily billings to the prior

and then multiplying this amount by the Net Collectable Percentage. The Loan may
be repaid or prepaid pursuant to Sections 2.5 or 2.6 and shall be mandatorily
prepaid pursuant to Section 2.6 by the Borrower. Subject to the provisions of
this Agreement, any amounts repaid may be reborrowed, up to the amounts
available under Section 2.1 at the time of such Borrowing, until prepaid the
business day immediately preceding the Termination Date. Lender's commitments to
make Advances shall expire, and the amount of Loan then outstanding shall mature
and be repaid by Borrower, without further action on the part of Lender, on the
Termination Date.

                  SECTION 2.3. INTEGRAL AMOUNTS OF LOANS. Advances may be of any
minimum amount.

                  SECTION 2.4. NOTICE OF BORROWING. Whenever Borrower desires to

proposed funding date. The Drawdown Request Form shall specify (i) the funding
date (which shall be a business day) with respect to the requested Loan and (ii)
the amount of the proposed Advance.

                  SECTION 2.5. REPAYMENT OF LOAN. All receipts from Borrower's
and its Affiliates' accounts receivable shall be deposited on a daily basis in a
bank depository lock box in accordance with the terms of the Lock Box Agreement.
Lender will debit the lock box account at the end of each day in payment of (i)
Lender's fees then due and payable in accordance with Section 2.7, (ii) amounts
then due and payable under the Other Loan Document, and (iii) on the first day
of each month with respect to interest accrued on the Loan during the preceding
month. Excess receipts remaining in the lock box account after the payment of
fees and interest shall be applied to the principal amount of the Loan on a
daily basis. Lender will credit Borrower's account in 


                                       9
<PAGE>   16

foregoing, after the occurrence and during the continuance of an Event of
Default, receipts in the lock box will be distributed in accordance with the
relative priorities set forth in and the terms and conditions of the
Intercreditor Agreement.

                  SECTION 2.6. PREPAYMENT. The Loan shall be subject to

terminated by any prepayment, without payment of the termination fee required
pursuant to Section 2.7. If any aging report or Borrowing Base report delivered
to Lender pursuant to Section 5.4 indicates that the outstanding Loan amount
exceeds the Borrowing Base, Borrower shall immediately prepay a portion of the
outstanding Loan amount such that after such prepayment the Borrowing Base
equals or exceeds the outstanding Loan amount.

immediately previous month-end. If Borrower elects to terminate this Agreement
at any time before the Termination Date, Borrower shall pay Lender a termination
fee of Eighty Thousand Dollars ($80,000) if terminated prior to the anniversary
date of this Agreement and Forty Thousand Dollars ($40,000) thereafter. Lender's
fees will be deducted, when due, directly from receipts from accounts receivable
deposited in accordance with Section 2.5.

                  SECTION 7.1. TITLE. Borrower has good and marketable title to
the Collateral, and the Liens granted to Lender pursuant to this Agreement are
fully perfected first-priority Liens, subject only to the terms of the
Intercreditor Agreement and the proper filing of any financing statement or
notice necessary to provide notice to third parties of the existence of such
Liens, in and to the Collateral with priority over the rights of every person in

person other than Lender except for Permitted Liens.

                  SECTION 7.2. FURTHER ASSURANCES. Borrower shall execute and

affidavits, reports, notices, schedules of accounts, letters of authority and
all other documents Lender may reasonably request, in form satisfactory to
Lender, to perfect and maintain perfected Lender's Liens in the Collateral and
in order to consummate fully all of the transactions contemplated under the Loan
Documents. Borrower and Guarantor hereby irrevocably make, constitute and
appoint Lender (and any of Lender's officers, employees or agents designated by
Lender) as Borrower's and its Affiliates' true and lawful attorney with power to
sign the name of Borrower and its Affiliates on any of the above-described
documents or on any other similar documents that need to be executed, recorded
or filed in order to perfect or continue perfected Lender's Liens in the
Collateral. The appointment of Lender as Borrower's and its Affiliates' attorney
is irrevocable as long as any Obligations are outstanding. Any person dealing

                  SECTION 7.3. LENDER'S DUTY OF CARE. Lender shall have no duty
of care with respect to the Collateral except that Lender shall exercise
reasonable care with respect to the Collateral in Lender's custody. Lender shall
be deemed to have exercised reasonable care if such property is accorded
treatment substantially equal to that which Lender accords its own property or
if Lender takes such action with respect to the Collateral as the Borrower shall
request or agree to in writing provided that no failure to comply with any such
request nor any omission to do any such act requested by the Borrower shall be
deemed a failure to exercise reasonable care. Lender's failure to take steps to
preserve rights against any parties or property shall not be deemed to be
failure to exercise reasonable care with respect to the Collateral in Lender's
custody. All risk, loss, damage or destruction of the Collateral shall be borne
by Borrower.

                  SECTION 7.4. REINSTATEMENT OF LIENS. If, at any time after
payment in full by Borrower of all Obligations and termination of Lender's
Liens, any payments on Obligations previously made by Borrower or any other
Person must be disgorged by Lender for any reason whatsoever (including, without
limitation, the insolvency, bankruptcy, or reorganization of Borrower or such
other Person), this Agreement and Lender's Liens granted hereunder shall be
reinstated as to all disgorged payments as though such payments had not been
made, and Borrower shall sign and deliver to Lender all documents and things
necessary to perfect all terminated Liens.

                  SECTION 7.5. LENDER EXPENSES. If Borrower or an Affiliate
fails to pay any moneys (whether taxes, assessments, insurance premiums or
otherwise) due to third persons or entities, fails to make any deposits or
furnish any required proof of payment or deposit or fails to discharge any Lien
not permitted hereby, all as required under the terms of this Agreement, then
Lender may, to the extent that it determines that such failure by Borrower or
its Affiliates could have a material adverse effect on Lender's interests in the
Collateral, in its discretion and without prior notice to Borrower, make payment
of the same or any part thereof. Any amounts paid or deposited by Lender shall
constitute Lender Expenses, shall become part of the Obligations, shall bear
interest at the rate of eighteen percent (18%) per annum, and shall be 

                                       20
<PAGE>   27

secured by the Collateral. Any payments made by Lender shall not constitute (a)
an agreement by Lender to make similar payments in the future or (b) a waiver by
Lender of any Event of Default under this Agreement. Lender need not inquire as
to, or contest the validity of, any such expense, tax, security interest,
encumbrance or Lien and the receipt of the usual official notice for the payment
of moneys to a governmental entity shall be conclusive evidence that the same
was validly due and owing.

                  Borrower shall immediately and without demand reimburse Lender
for all sums expended by Lender that constitute Lender Expenses, and Borrower
hereby authorizes and approves all advances and payments by Lender for items
constituting Lender Expenses.

                  SECTION 7.6. INSPECTION OF RECORDS. During usual business
hours, Lender shall have the right to inspect and verify Borrower's Books in
order to verify the amount or condition of, or any other matter relating to, the
Collateral and Guarantor's and Borrower's financial condition and Borrower
agrees to reimburse Lender for its costs and expenses in doing so and to copy
and make extracts therefrom. Guarantor and Borrower waive the right to assert a
confidential relationship, if any, it may have with any accounting firm or
service bureau in connection with any information requested by Lender pursuant
to this Agreement and agrees that Lender may directly contact any such
accounting firm or service bureau in order to obtain such information.

                  SECTION 7.7. WAIVERS. Except as specifically provided for
herein, Borrower waives demand, protest, notice of protest, notice of default or
dishonor, notice of payment and nonpayment, notice of any default, nonpayment at
maturity, release, compromise, settlement, extension or renewal of any or all
commercial paper, accounts, documents, instruments, chattel paper and guaranties
at any time held by Lender on which Borrower may in any way be liable.

Forty Thousand Dollars ($240,000) with respect to such unit of equipment and
assets that are related to the operation of such unit of equipment; provided,
however, that Borrower and its Affiliates are expressly permitted to remain
lessee under, and make all payments required by, any leases with GE, entered

interest or any other payment on the Note or any other Obligation when due and

however, with respect to any default under the GE Affected Debt (as defined in
the Intercreditor Agreement) an Event of Default shall not be deemed to exist
under this Agreement until such default constitutes an "Event of Default", as
such term is defined with respect to the GE Affected Debt;

Affiliates, with or without judicial process, and take possession of the
Collateral; provided however, that Lender may only exercise such remedy if it

premises and use the premises for the purpose of collecting, preparing and
disposing of the Collateral, without any liability for rent or occupancy
charges. Borrower shall, upon request of Lender, assemble the Collateral and any
records pertaining thereto and make them available at a place designated by

name to change the address for delivery of Borrower's or its Affiliates' mail to
an address designated by Lender, receive and open all mail addressed to Borrower
or an Affiliate, copy all mail, return all mail relating to Collateral, and hold
all other mail available for pickup by Borrower or an Affiliate.

                  (i) Lender may sell the Collateral at public or private sale
and is not required to repossess Collateral before selling it. Any requirement
of reasonable notice of any disposition of the Collateral shall be satisfied if
such notice is sent to Borrower, ten (10) days prior to such disposition by any
of the methods provided in Section 13.5 hereof. Borrower shall be credited with
the net proceeds of such sale only when they are actually received by Lender,
and Borrower shall continue to be liable for any deficiency remaining after the
Collateral is sold or collected.

                  (j) If the sale is to be a public sale, Lender shall also give
notice of the time and place by publishing a notice one time at least five (5)
days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held.

                  (k) To the maximum extent permitted by applicable law, Lender
may be the purchaser of any or all of the Collateral at any public sale and
shall be entitled, for the purpose of bidding and making settlement or payment
of the purchase price for all or any portion of the Collateral sold at any
public sale, to use and apply all or any part of the Obligations as a credit on
account of the purchase price of any Collateral payable by Lender at such sale.

                  SECTION 11.2. POWER OF ATTORNEY. Guarantor and Borrower hereby
appoints Lender (and any of Lender's officers, employees, or agents designated
by Lender) as Guarantor's and Borrower's attorney, with power whether before or
after the occurrence of an Event of Default: (a) to endorse Borrower's or its
Affiliates' name on any checks, notes, acceptances, money orders, drafts or
other forms of payment or security that may come into Lender's possession; (b)
to sign Borrower's or its Affiliates' name on 

                                       34
<PAGE>   41

drafts against Account Debtors, on schedules and assignments of Accounts, on
verifications of Accounts, and on notices to Account Debtors; (c) to notify the
post office authorities to change the address for delivery of Borrower's or its
Affiliates' mail to an address designated by Lender, to receive and open all
mail addressed to Borrower or an Affiliate and to retain all mail relating to
the Collateral and forward all other mail to Borrower or an Affiliate; (d) to
send requests for verification of Accounts; (e) to execute UCC Financing
Statements; and (f) to do all things necessary to carry out this Agreement. The
appointment of Lender as Borrower's attorney and each and every one of Lender's
rights and powers, being coupled with an interest, are irrevocable as long as
any Obligations are outstanding. Lender agrees not to exercise the power granted
in clauses 11.2(a) through 11.2(c) prior to the occurrence of an Event of
Default and agrees not to exercise the power granted in clause 11.2(d) prior to
notification of Borrower of its intent to do so, but such limitations do not
limit the effectiveness of such power of attorney at any time. Any person
dealing with Lender shall be entitled to rely conclusively on any written or
oral statement of Lender that this power of attorney is in effect. Lender may
also use Borrower's stationery in connection with exercising its rights and
remedies and performing the Obligations of Borrower.

                  SECTION 11.3. EXPENSES SECURED. All expenses, including
attorney fees, incurred by Lender in the exercise of its rights and remedies
provided in this Agreement, in the Other Loan Document or by law shall be
payable by Borrower to Lender, shall be part of the Obligations, and shall be
secured by the Collateral.

                  SECTION 11.4. EQUITABLE RELIEF. Borrower recognizes that in
the event Borrower fails to perform, observe, or discharge any of its
Obligations or liabilities under this Agreement, no remedy of law will provide
adequate relief to Lender, and Borrower agrees that Lender shall be entitled to
temporary and permanent injunctive relief in any such case without the necessity
of proving actual damages.

                  SECTION 11.5. REMEDIES ARE CUMULATIVE. No remedy set forth
herein is exclusive of any other available remedy or remedies, but each is
cumulative and in addition to every other right or remedy given under this
Agreement or under any other agreement between Lender and Borrower or Guarantor
or now or hereafter existing at law or in equity or by statute. Lender may

                                       35
<PAGE>   42

pursue its rights and remedies concurrently or in any sequence, and no exercise
of one right or remedy shall be deemed to be an election. No delay by Lender
shall constitute a waiver, election or acquiescence by it. Borrower on its
behalf waives any rights to require Lender to (i) proceed against Guarantor or
any other party; or (ii) proceed against or exhaust any security held from
Guarantor. Lender may at any time and from time to time, without notice to, or
consent of, Borrower, and without affecting or impairing the obligation of
Borrower hereunder do any of the following: (i) renew or extend any Obligations
of Guarantor, or of any other party at any time directly or contingently liable
for payment of any of the Obligations of Guarantor; (ii) accept partial payments
of the Obligations of Guarantor; (iii) settle, release (by operation of law or
otherwise), compound, compromise, collect or liquidate any of the Obligations of
Guarantor and the security therefor in any manner; (iv) consent to the transfer
or sale of any security or bid and purchase at any sale of any security of
Guarantor. Borrower expressly agrees that the validity of this Agreement and the
Obligations of Borrower shall not be terminated, affected or impaired by reason
of the waiving, delaying, exercising or non-exercising, of any of Lender's
rights against Guarantor or as a result of the substitution, release,
repossession, sale, disposition or destruction of any Collateral securing any
Obligations of Guarantor. Lender shall not be released or discharged, either in
whole or in part, by Lender's failure or delay to perfect or continue the
perfection of any security interest in any Collateral which secures the
Obligations of Guarantor or to protect the property covered by such security
interest.

                                   SECTION 12

                                    INDEMNITY

                  SECTION 12.1. GENERAL INDEMNITY. Borrower shall protect,
indemnify and defend and save harmless Lender and its directors, officers,
agents and employees from and against any and all loss, cost, liability
(including negligence, tort and strict liability), expense, damage, suits or
demands (including fees and disbursements of counsel) on account of any suit or
proceeding before any Governmental Authority which arises from the transactions
contemplated in this Agreement or otherwise arising in connection with or
relating to the Loan and any security therefor, 

                                       36
<PAGE>   43

unless such suit, claim or damages are caused by the negligence or intentional
malfeasance of Lender or its directors, officer, agents or employees. Upon
receiving knowledge of any suit, claim or demand asserted by a third-party that
Lender believes is covered by this indemnity, Lender shall give Borrower timely
notice of the matter and an opportunity to defend it, at Borrower's sole cost
and expense, with legal counsel acceptable to Lender. Lender may, at its option,
also require Borrower to so defend the matter. This obligation on the part of
Borrower shall survive the termination of this Agreement and the repayment of
the Note.

                                   SECTION 13

                                  MISCELLANEOUS

                  SECTION 13.1. DELAY AND WAIVER. No delay or omission to
exercise any right shall impair any such right or be a waiver thereof, but any
such right may be exercised from time to time and as often as may be deemed
expedient. A waiver on one occasion shall be limited to that particular
occasion.

                  SECTION 13.2. COMPLETE AGREEMENT. This Agreement and the
Schedules are the complete agreement of the parties hereto and supersede all
previous understandings relating to the subject matter hereof. This Agreement
may be amended only by an instrument in writing that explicitly states that it
amends this Agreement and is signed by the party against whom enforcement of the
amendment is sought. This Agreement may be executed in counterparts, each of
which will be an original and all of which will constitute a single agreement.

                  SECTION 13.3. SEVERABILITY; HEADINGS. If any part of this
Agreement or the application thereof to any person or circumstance is held
invalid, the remainder of this Agreement shall not be affected thereby. The
section headings herein are included for convenience only and shall not be
deemed to be a part of this Agreement.

                  SECTION 13.4. BINDING EFFECT. This Agreement shall be binding
upon and inure to the benefit of the respective legal representatives,
successors and assigns of the parties hereto; however, Borrower may not assign
any of its rights or delegate any of its Obligations hereunder. Lender (and any
subsequent assignee) 

                                       37
<PAGE>   44

may transfer and assign this Agreement and deliver the Collateral to the
assignee, who shall thereupon have all of the rights of Lender; and Lender (or
such subsequent assignee who in turn assigns as aforesaid) shall then be
relieved and discharged of any responsibility or liability with respect to this
Agreement and said Collateral.

                  SECTION 13.5. NOTICES. Any notices under or pursuant to this
Agreement shall be deemed duly sent when delivered in hand or when mailed by
registered or certified mail, return receipt requested, or when delivered by
courier or when transmitted by telex, telecopy, or similar electronic medium to
the following addresses:

initiates proceedings have jurisdiction over all matters arising out of this
Agreement and that service of process in any such proceeding shall be effective

Agreement. Borrower waives any right it may have to assert the defense of forum
non conveniens or to object to such venue and hereby consents to any
court-ordered relief.

encumbrance, charge or Lien that, in the opinion of Lender, appears to be prior
or superior to its Lien and pay all reasonable expenses incurred in connection
therewith.

                 (f) Lender may (i) endorse Borrower's or its Affiliates' name
on all checks, notes, drafts, money orders or other forms of payment of or
security for Accounts or other Collateral; (ii) sign Borrower's or its
Affiliates' name on drafts drawn on Account Debtors or issuers of letters of
credit; and (iii) notify the postal authorities in Borrower's or its Affiliates'
name to change the address for delivery of Borrower's or its Affiliates' mail to
an address designated by Lender, receive and open all mail addressed to Borrower
or an Affiliate, copy all mail, return all mail relating to Collateral, and hold
all other mail available for pickup by Borrower or an Affiliate.

                 (g) Lender may sell the Collateral at public or private sale
and is not required to repossess Collateral before selling it. Any requirement
of reasonable notice of any disposition of the Collateral shall be satisfied if
such notice is sent to Borrower, ten (10) days prior to such disposition by any
of the methods provided in Section 11.5 hereof. Borrower shall be credited with
the net proceeds of such sale only when they are actually received by Lender,
and Borrower shall continue to be liable for any deficiency remaining after the
Collateral is sold or collected.

                 (h) If the sale is to be a public sale, Lender shall also give
notice of the time and place by publishing a notice one time at least five (5)
days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held.

                 (i) To the maximum extent permitted by applicable law, Lender
may be the purchaser of any or all of the Collateral at any public sale and
shall be entitled, for the purpose of bidding and making settlement or payment
of the purchase price for all or any portion of the Collateral sold at any
public sale, to use and apply all or any part of the Obligations as a credit on
account of the purchase price of any Collateral payable by Lender at such sale.

                 SECTION 9.2. POWER OF ATTORNEY. Guarantor and Borrower hereby
appoint Lender (and any of Lender's officers, employees, or

                                       25


<PAGE>   30

agents designated by Lender) as Guarantor's and Borrower's attorney, with power
whether before or after the occurrence of an Event of Default: (a) to endorse
Borrower's or its Affiliates' name on any checks, notes, acceptances, money
orders, drafts or other forms of payment or security that may come into Lender's
possession; (b) to sign Borrower's or its Affiliates' name on drafts against
Account Debtors, on schedules and assignments of Accounts, on verifications of
Accounts, and on notices to Account Debtors; (c) to notify the post office
authorities to change the address for delivery of Borrower's or its Affiliates'
mail to an address designated by Lender, to receive and open all mail addressed
to Borrower or an Affiliate and to retain all mail relating to the Collateral
and forward all other mail to Borrower or an Affiliate; (d) to send requests for
verification of Accounts; (e) to execute UCC Financing Statements; and (f) to do
all things necessary to carry out this Agreement. The appointment of Lender as
Borrower's attorney and each and every one of Lender's rights and powers, being
coupled with an interest, are irrevocable as long as any Obligations are
outstanding. Lender agrees not to exercise the power granted in clauses 9.2(a)
through 9.2(c) prior to the occurrence of an Event of Default and agrees not to
exercise the power granted in clause 9.2(d) prior to notification of Borrower of
its intent to do so, but such limitations do not limit the effectiveness of such
power of attorney at any time. Any person dealing with Lender shall be entitled
to rely conclusively on any written or oral statement of Lender that this power
of attorney is in effect. Lender may also use Borrower's stationery in
connection with exercising its rights and remedies and performing the
Obligations of Borrower.

                 SECTION 9.3. EXPENSES SECURED. All expenses, including attorney
fees, incurred by Lender in the exercise of its rights and remedies provided in
this Agreement, in the Other Loan Document or by law shall be payable by
Borrower to Lender, shall be part of the Obligations, and shall be secured by
the Collateral.

                 SECTION 9.4. EQUITABLE RELIEF. Borrower recognizes that in the
event Borrower fails to perform, observe, or discharge any of its Obligations or
liabilities under this Agreement, no remedy of law will provide adequate relief
to Lender, and Borrower agrees that Lender shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

                 SECTION 9.5. REMEDIES ARE CUMULATIVE. No remedy set forth
herein is exclusive of any other available remedy or remedies, but each is
cumulative and in addition to every other right or remedy given under this
Agreement or under any other agreement between Lender and Borrower or Guarantor
or now or hereafter existing at law or in equity or by statute. Lender may
pursue its rights and remedies concurrently or in any sequence, and no exercise
of one right or remedy shall be deemed to be an election. No delay by Lender
shall constitute a waiver, election, or acquiescence by it. Borrower on its
behalf waives any rights to

                                       26


<PAGE>   31

require Lender to (i) proceed against Guarantor or any other party; or (ii)
proceed against or exhaust any security held from Guarantor. Lender may at any
time and from time to time, without notice to, or consent of, Borrower, and
without affecting or impairing the obligation of Borrower hereunder do any of
the following: (i) renew or extend any Obligations of Guarantor, or of any other
party at any time directly or contingently liable for payment of any of the
Obligations of Guarantor; (ii) accept partial payments of the Obligations of
Guarantor; (iii) settle, release (by operation of law or otherwise), compound,
compromise, collect or liquidate any of the Obligations of Guarantor and the
security therefor in any manner; (iv) consent to the transfer or sale of any
security or bid and purchase at any sale of any security of Guarantor. Borrower
expressly agrees that the validity of this Agreement and the Obligations of
Borrower shall not be terminated, affected or impaired by reason of the waiving,
delaying, exercising or non-exercising, of any of Lender's rights against
Guarantor or as a result of the substitution, release, repossession, sale,
disposition or destruction of any Collateral securing any Obligations of
Guarantor. Lender shall not be released or discharged, either in whole or in
part, by Lender's failure or delay to perfect or continue the perfection of any
security interest in any Collateral which secures the Obligations of Guarantor
or to protect the property covered by such security interest.

                                   SECTION 10

                                    INDEMNITY

                 SECTION 10.1. GENERAL INDEMNITY. Borrower shall protect,
indemnify and defend and save harmless Lender and its directors, officers,
agents and employees from and against any and all loss, cost, liability
including negligence, tort and strict liability), expense, damage, suits or
demands (including fees and disbursements of counsel) on account of any suit or
proceeding before any Governmental Authority which arises from the transactions
contemplated in this Agreement or otherwise arising in connection with or
relating to the Loan and any security therefor, unless such suit, claim or
damages are caused by the negligence or intentional malfeasance of Lender or its
directors, officer, agents or employees. Upon receiving knowledge of any suit,
claim or demand asserted by a third-party that Lender believes is covered by
this indemnity, Lender shall give Borrower timely notice of the matter and an
opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel acceptable to Lender. Lender may, at its option, also require Borrower
to so defend the matter. This obligation on the part of Borrower shall survive
the termination of this Agreement and the repayment of the Note.

                 SECTION 10.2. SPECIFIC ENVIRONMENTAL INDEMNITY. Borrower hereby
agrees unconditionally to indemnify, defend and

                                       27
<PAGE>   32

hold harmless Lender, its directors, officers, employees and agents against any
loss, liability, damage or expense or claim arising under any Environmental
Laws having jurisdiction over the property or assets of Borrower or its
Affiliates or any portion thereof or its use.


                                   SECTION 11

                                 MISCELLANEOUS

                 SECTION 11.1.  DELAY AND WAIVER.  No delay or omission to
exercise any right shall impair any such right or be a waiver thereof, but any
such right may be exercised from time to time and as often as may be deemed
expedient.  A waiver on one occasion shall be limited to that particular
occasion.

                 SECTION 11.2.  COMPLETE AGREEMENT.  This Agreement and the
Schedules are the complete agreement of the parties hereto and supersede all
previous understandings relating to the subject matter hereof.  This Agreement
may be amended only by an instrument in writing that explicitly states that it
amends this Agreement and is signed by the party against whom enforcement of
the amendment is sought.  This Agreement may be executed in counterparts, each
of which will be an original and all of which will constitute a single
agreement.

                 SECTION 11.3.  SEVERABILITY; HEADINGS.  If any part of this
Agreement or the application thereof to any person or circumstance is held
invalid, the remainder of this Agreement shall not be affected thereby.  The
section headings herein are included for convenience only and shall not be
deemed to be a part of this Agreement.

                 SECTION 11.4.  BINDING EFFECT.  This Agreement shall be
binding upon and inure to the benefit of the respective legal representatives,
successors and assigns of the parties hereto; however, Borrower may not assign
any of its rights or delegate any of its Obligations hereunder.  Lender (and
any subsequent assignee) may transfer and assign this Agreement and deliver the
Collateral to the assignee, who shall thereupon have all of the rights of
Lender; and Lender (or such subsequent assignee who in turn assigns as
aforesaid) shall then be relieved and discharged of any responsibility or
liability with respect to this Agreement and said Collateral.

                 SECTION 11.5.  NOTICES.  Any notices under or pursuant to this
Agreement shall be deemed duly sent when delivered in hand or when mailed by
registered or certified mail, return receipt requested, or when delivered by
courier or when transmitted by telex, telecopy, or similar electronic medium to
the following addresses:

                       UNCONDITIONAL CONTINUING GUARANTY
                                (Loan Agreement)

THIS UNCONDITIONAL CONTINUING GUARANTY ("Guaranty") is made and entered into as 
of May 17, 1995, for the benefit of _________________________________ 
("Lender"), whose principal place of business is located at 4041 MacArthur 
Ave., Suite 401, Newport Beach, California 92660, by American Shared Hospital 
Services, a California corporation ("Guarantor"), whose principal place of 
business is located at Four Embarcadero Center, Suite 3620, San Francisco 
California 94111.

RECITALS

         A.  Guarantor directly or indirectly owns all of the ownership
interests in American Shared-CuraCare, a California general partnership, and
CuraCare, Inc., a Delaware corporation ("collectively and individually,
"Borrower").


AGREEMENT

        1.  Guaranty.  In order to induce Lender, and in consideration thereof, 
to enter into that certain Loan and Security Agreement dated as of the date 
hereof (the "Agreement") with Borrower, Guarantor and Ernest A. Bates, M.D., 
and any future agreements with Borrower, Guarantor unconditionally, absolutely 
and irrevocably guarantees and promises to Lender to pay, perform and 
discharge, any and all present and future indebtedness, liabilities and 
obligations (collectively "Obligations") of Borrower to Lender, including but 
not limited to the repayment to Lender of all sums presently due and owing and 
of all sums that shall in the future become due and owing from Borrower whether 
arising under the Agreement or otherwise.

        2.  Obligations.  The Obligations of Borrower include any and all 
loans, advances, indebtedness and other obligations owed by Borrower to Lender 
of every description whether now existing or hereafter arising (including those 
owed to others by Borrower and acquired by Lender by purchase, assignment or 
otherwise) and include Obligations that are: (a) direct or indirect; (b) fixed 
or contingent; (c) primary or as guarantor or surety; (d) liquidated or 
unliquidated; (e) matured or unmatured; (f) acquired by pledge, assignment, 
security interest or purchase; (g) secured or unsecured; (h) primary or 
secondary; (i) joint, several or joint and several; (j) represented by letters 
of credit now or hereafter issued by Lender for the benefit of or at the 
request of Borrower; and (k) all of Lender's expenses, included but not limited 
to (i) all reasonable costs or expenses, including without limitation, taxes 
and insurance premiums, required to be paid by Borrower under the Agreement 
that are paid or advanced by Lender, (ii) all filing, recording, publication 
and search fees paid or incurred by Lender in connection with Lender's 
transactions with Borrower, (iii) all costs and expenses incurred by Lender to 
correct any Event of Default (as defined in the Agreement) or enforce any 
provision of the Agreement, or in gaining possession of, maintaining, handling, 
preserving, storing, shipping, selling, preparing for sale or advertising to 
sell any security for the Obligations, whether or not a sale is consummated, 
after the occurrence of an Event of Default (iv) all costs and expenses of suit 
incurred by Lender and enforcing or defending the Agreement or any portion 
thereof, and (v) all reasonable Lender's attorney's fees and expenses incurred 
in advising, structuring, drafting,

                                       1
<PAGE>   2
reviewing, negotiating, amending, terminating, enforcing, defending or 
concerning the Agreement or any portion thereof, irrespective  of whether suit 
is brought, and includes each Borrower's prompt, full and faithful performance, 
observance and discharge of each and every term, condition, agreement, 
representation, warranty, undertaking and provision to be performed by Borrower 
under the Agreement.

        3.  Attorneys' Fees.  Guarantor agrees to pay Lender the costs and 
expenses of the enforcement of this Guaranty, including attorneys' fees.

        4.  Waivers.

            (a)  Scope of Risk Defenses.  Lender may at any time and from time 
to time, without notice to, or the consent of, Guarantor, and without affecting 
or impairing the obligation of Guarantor hereunder, do any of the following:  
(i) renew or extend any Obligations of Borrower, of its customers, of any 
co-guarantors (whether hereunder or under a separate instrument) or of any 
other party at any time directly or contingently liable for the payment of any 
of the Obligations; (ii) accept partial payments of the Obligations; (iii) 
settle, release (by operation of law or otherwise), compound, compromise, 
collect or liquidate any of the Obligations and the security therefor in any 
manner; (iv) consent to the transfer or sale of security, or (v) bid and 
purchase at any sale of any security.

            (b)  Primary Obligation Defenses.  Guarantor waives any rights to 
require Lender to (i) proceed against Borrower or any other party; (ii) proceed 
against or exhaust any security held from Borrower; or (iii) pursue any other 
remedy in Lender's power whatsoever. Guarantor waives any defense based on or 
arising out of any defense of Borrower other than payment in full of the 
Obligations, including without limitation any defense based on or arising out 
of any disability of Borrower, or the unenforceability of the Obligations or 
any part thereof from any cause, or the cessation from any cause of the 
liability of Borrower.

            (c)  Commercially Reasonable Sale and Anti-deficiency Laws.  Lender 
may, at Lender's election, foreclose on any security held by Lender by one or 
more judicial or nonjudicial sales, whether or not every aspect of any such 
sale is commercially reasonable, or exercise any other right or remedy Lender 
may have against Borrower, or any security, without affecting or impairing in 
any way the liability of Guarantor except to the extent the Obligations have 
been paid.  Guarantor waives any defense arising out of any such election by 
Lender, even though such election operates to impair or extinguish any right of 
reimbursement or subrogation or other right or remedy of Lender against 
Borrower or any security. In the absence of agreeing to the waivers contained 
in this subsection 4(c), Guarantor may have the right of subrogation or 
reimbursement against a Borrower.  For example, if Lender elects to foreclose, 
by nonjudicial sale, any deeds of trust securing any indebtedness of Borrower 
to Lender, causing Guarantor to lose any such rights or create defenses to 
enforcement of this Guaranty, Guarantor gives up any such potential defenses by 
agreeing to these waivers.  Guarantor also expressly waives any defense or 
benefit that may be derived from California Code of Civil Procedure Sections 
580a, 580d or 726 or comparable provisions of the laws of any other state and 
all securityship defenses it would otherwise under California law or under the 
laws of any other state.



                                       2
<PAGE>   3
            (d)     Disclosure Defenses.   Guarantor expressly waives all
set-offs and counterclaims and waives all notices, protests and demands
including, but not limited to, notice of default in payment or in the
performance or observance of any of the terms, provisions, covenants or
conditions contained in any agreement between Lender and any Borrower.

            (e)     Borrowers' Defenses On Underlying Obligations.   Guarantor
expressly agrees that the validity of this Guaranty and the obligations of
Guarantor shall not be terminated, affected or impaired by reason of the
waiving, delaying, exercising or nonexercising, of any of Lender's rights
against any Borrower pursuant to any of the Agreement against Guarantor by
reason of this Guaranty or as a result of the substitution, release,
repossession, sale, disposition or destruction of any collateral securing the
Obligations.

            (f)     Impairment of Collateral Defenses.   Guarantor shall not be
released or discharged, either in whole or in part, by Lender's failure or delay
to perfect or continue the perfection of any security interest in any property
which secures the Obligations of any Borrower or Guarantor to Lender, or to
protect the property covered by such security interest.

            (g)     Guarantor's Right to Revoke.   Guarantor expressly waives
the right to revoke or terminate this continuing Guaranty, including any
statutory right of revocation under California Civil Code Section 2815, or
comparable provisions of the laws of any other state.

        5.  Financial Condition of Borrower.   Guarantor assumes all 
responsibility for being and keeping informed of Borrower's financial condition 
and assets and of all other circumstances bearing upon the risk of nonpayment 
of the Obligations and the nature, scope and extent of the risks which 
Guarantor assumes and incurs hereunder, and agrees that Lender shall have no 
duty to advise Guarantor of information known to it regarding such 
circumstances or risks.

        6.  Guarantor Not Entitled To Subrogation.   No payment by Guarantor 
hereunder shall entitle Guarantor, by subrogation, indemnity, reimbursement, 
contribution or otherwise, to any payment by Borrower or to any subrogation, 
indemnity, reimbursement or contribution out of the property of Borrower until 
the Obligations have been paid in full.

        7.  Recovery of Preferences.   If a claim is made upon Lender at any 
time for repayment or recovery of any amount(s) or other value received by 
Lender, from any source, in payment of or on account of any of the Obligations 
of Borrower guaranteed hereunder and Lender repays or otherwise becomes liable 
for all or any part of such claim by reason of (a) any judgment, decree or 
order of any court or administrative body having competent jurisdiction, or (b) 
any settlement or compromise of any such claim, Guarantor shall remain liable 
to Lender hereunder for the amount so repaid or for which Lender is otherwise 
liable to the same extent as if such amount(s) had never been received by 
Lender, notwithstanding any termination hereof or the termination of any 
agreements evidencing any of the Obligations of Borrower.

        8.  Events Of Default.   The occurrence of any Event of Default under 
the Agreement shall constitute an event of default under this Guaranty and upon

Guarantor's legal representatives, successors and assigns, and shall inure to 
the benefit of Lender's successors and assigns, including, but not limited to, 
any party to whom Lender may assign the Agreement or any other agreements, and 
Guarantor hereby waives notice of any such assignment. All of Lender's rights

guaranteed nor any other circumstance which might be a legal defense of a 
guarantor shall affect, impair, or be a defense to this Guaranty. Each of the 
persons who has signed this or any other Guaranty has unconditionally delivered 
it to Lender, and the failure to sign this or any other Guaranty by any other 
person shall not discharge the liability of any signer. The unconditional 
liability of the signer applies whether the signer is jointly and severally 
liable for the entire amount of the debt, or for only a pro-rata portion.

        11.  Choice of Law and Forum. THIS GUARANTY SHALL IN ALL RESPECTS BE 
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF 
CALIFORNIA, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE AND

AGREEMENT

        1.  Guaranty. In order to induce Lender, and in consideration thereof, 
to enter into that certain Loan and Security Agreement dated as of the date 
hereof (the "Agreement") with Borrower, Guarantor and Individual Guarantor and 
any future agreements with Borrower, Individual Guarantor unconditionally, 
absolutely and irrevocably guarantees and promises to Lender to pay, perform 
and discharge, any and all present and future indebtedness, liabilities and 
obligations (collectively "Obligations") of Borrower to Lender, including
but not limited to the repayment to Lender of all sums presently due and owing 
and of all sums that shall in the future become due and owing from Borrower 
whether arising under the Agreement or otherwise.

        2.  Obligations. The Obligations of Borrower include any and all loans, 
advances, indebtedness and other obligations owned by Borrower to Lender of 
every description whether now existing or hereafter arising (including those 
owed to others by Borrower and acquired by Lender by purchase, assignment or

or contingent; (c) primary or as guarantor or surety; (d) liquidated or 
unliquidated; (e) matured or unmatured; (f) acquired by pledge, assignment, 
security interest or purchase; (g) secured or unsecured; (h) primary or

and insurance premiums, required to be paid by Borrower under the Agreement 
that are paid or advanced by Lender, (ii) all filing, recording, publication 
and search fees paid or incurred by Lender in connection with Lender's 
transactions with Borrower, (iii) all costs and expenses incurred by Lender to 
correct any Event of Default (as defined in the Agreement) or enforce any 
provision of the Agreement, or in gaining possession of, maintaining, handling, 
preserving, storing, shipping, selling, 




                                       1
<PAGE>   2
preparing for sale or advertising to sell any security for the Obligations, 
whether or not a sale is consummated, after the occurrence of an Event of 
Default (iv) all costs and expenses of suit incurred by Lender and enforcing 
or defending the Agreement or any portion thereof, and (v) all reasonable 
Lender's attorney's fees and expenses incurred in advising, structuring, 
drafting, reviewing, negotiating, amending, terminating, enforcing, defending 
or concerning the Agreement or any portion thereof, irrespective of whether 
suit is brought, and includes each Borrower's prompt, full and faithful 
performance, observance and discharge of each and every term, condition, 
agreement, representation, warranty, undertaking and provision to be performed 
by Borrower under the Agreement.

        3.  Attorneys' Fees.  Individual Guarantor agrees to pay Lender the 
costs and expenses of the enforcement of this Guaranty, including attorneys'
fees.

        4.  Waivers.

            (a)  Scope of Risk Defenses.  Lender may at any time and from time 
to time, without notice to, or the consent of, Individual Guarantor, and 
without affecting or impairing the obligation of Individual Guarantor 
hereunder, do any of the following: (i) renew or extend any Obligations of 
Borrower, of its customers, of any co-guarantors (whether hereunder or under a 
separate instrument) or of any other party at any time directly or contingently 
liable for the payment of any of the Obligations; (ii) accept partial payments 
of the Obligations; (iii) settle, release (by operation of law or otherwise), 
compound, compromise, collect or liquidate any of the Obligations and the 
security therefor in any manner; (iv) consent to the transfer or sale of 
security, or (v) bid and purchase at any sale of any security.

            (b)  Primary Obligation Defenses.  Individual Guarantor waives any 
rights to require Lender to (i) proceed against Borrower or any other party; 
(ii) proceed against or exhaust any security held from Borrower; or (iii) 
pursue any other remedy in Lender's power whatsoever. Individual Guarantor 
waives any defense based on or arising out of any defense of Borrower other 
than payment in full of the Obligations, including without limitation any 
defense based on or arising out of any disability of Borrower, or the 
unenforceability of the Obligations or any part thereof from any cause, or the 
cessation from any cause of the liability of Borrower.

            (c)  Commercially Reasonable Sale and Anti-deficiency Laws.  Lender 
may, at Lender's election, foreclose on any security held by Lender by one or 
more judicial or nonjudicial sales, whether or not every aspect of any such 
sale is commercially reasonable, or exercise any other right or remedy Lender 
may have against Borrower, or any security, without affecting or impairing in 
any way the liability of Individual Guarantor except to the extent the 
Obligations have been paid. Individual Guarantor waives any defense arising out 
of any such election by Lender, even though such election operates to impair or 
extinguish any right of reimbursement or subrogation or other right or remedy 
of Lender against Borrower or any security. In the absence of agreeing to the 
waivers contained in this subsection 4(c), Individual Guarantor may have the 
right of subrogation or reimbursement against a Borrower. For example, if 
Lender elects to foreclose, by nonjudicial sale, any deeds of trust securing 
any indebtedness of Borrower to Lender, causing Individual Guarantor to lose 
any such rights or create defenses to enforcement of this Guaranty, Individual 
Guarantor gives up any such 

                                       2
<PAGE>   3
potential defenses by agreeing to these waivers. Individual Guarantor also 
expressly waives any defense or benefit that may be derived from California 
Code of Civil Procedure Sections 580a, 580d or 726 or comparable provisions of 
the laws of any other state and all securityship defenses it would otherwise 
under California law or under the laws of any other state.

            (d)  Disclosure Defenses.  Individual Guarantor expressly waives all
set-offs and counterclaims and waives all notices, protests and demands
including, but not limited to, notice of default in payment or in the
performance or observance of any of the terms, provisions, covenants or
conditions contained in any agreement between Lender and any Borrower.

            (e)  Borrowers' Defenses On Underlying Obligations.  Individual
Guarantor expressly agrees that the validity of this Guaranty and the
obligations of Individual Guarantor shall not be terminated, affected or
impaired by reason of the waiving, delaying, exercising or nonexercising, of any
of Lender's rights against any Borrower pursuant to any of the Agreement against
Individual Guarantor by reason of this Guaranty or as a result of the
substitution, release, repossession, sale, disposition or destruction of any
collateral securing the Obligations.

            (f)  Impairment of Collateral Defenses.  Individual Guarantor
shall not be released or discharged, either in whole or in part, by Lender's
failure or delay to perfect or continue the perfection of any security interest
in any property which secures the Obligations of any Borrower or Individual
Guarantor to Lender, or to protect the property covered by such security
interest.

            (g)  Individual Guarantor's Right to Revoke.  Individual Guarantor 
expressly waives the right to revoke or terminate this continuing Guaranty, 
including any statutory right of revocation under California Civil Code Section 
2815, or comparable provisions of the laws of any other state.

        5.  Financial Condition of Borrower.  Individual Guarantor assumes all 
responsibility for being and keeping informed of Borrower's financial condition 
and assets and of all other circumstances bearing upon the risk of nonpayment
of the Obligations and the nature, scope and extent of the risks which
Individual Guarantor assumes and incurs hereunder, and agrees that Lender shall
have no duty to advise Individual Guarantor of information known to it
regarding such circumstances or risks.

        6.  Individual Guarantor Not Entitled To Subrogation.  No payment by 
Individual Guarantor hereunder shall entitle Individual Guarantor, by 
subrogation, indemnity, reimbursement, contribution or otherwise, to any 
payment by Borrower or to any subrogation, indemnity, reimbursement or 
contribution out of the property of Borrower until the Obligations have been 
paid in full.

        7.  Recovery of Preferences.  If a claim is made upon Lender at any 
time for repayment or recovery of any amount(s) or other value received by 
Lender, from any source, in payment of or on account of any of the Obligations 
of Borrower guaranteed hereunder and Lender repays or otherwise becomes liable 
for all or any part of such claim by reason of (a) any judgment, decree or 
order of any court or administrative body having competent jurisdiction,

                                       3
<PAGE>   4
or (b) any settlement or compromise of any such claim, Individual Guarantor 
shall remain liable to Lender hereunder for the amount so repaid or for which 
Lender is otherwise liable to the same extent as if such amount(s) had never 
been received by Lender, notwithstanding any termination hereof or the 
termination of any agreements evidencing any of the Obligations of Borrower.

        8.      Events of Default.   The occurrence of any Event of Default 
under the Agreement shall constitute an event of default under this Guaranty 
and upon the occurrence thereof and at Lender's election without notice or 
demand, Individual Guarantor's obligations hereunder shall become due, payable 
and enforceable against Individual Guarantor, whether or not the Obligations 
are then due and payable.

        9.      Binding On Successors and Assigns.    This Guaranty shall bind 
Individual Guarantor's legal representatives, successors and assigns, and shall 
inure to the benefit of Lender's successors and assigns, including, but not 
limited to, any party to whom Lender may assign the Agreement or any other 
agreements, and Individual Guarantor hereby waives notice of any such 
assignment. All of Lender's rights are cumulative and not alternative.

        10.     Miscellaneous.    This Guaranty contains the entire agreement 
of the parties hereto and no other oral or written agreement exists. This 
Guaranty may not be amended or modified except by a writing signed by Lender 
and Individual Guarantor. This Guaranty is a valid and subsisting legal 
instrument and no provision which may be deemed unenforceable shall in any way 
invalidate any other provision or provisions, all of which shall remain in full 
force and effect. No invalidity, irregularity or unenforceability of all or any 
part of the Obligations guaranteed nor any other circumstance which might be a 
legal defense of a guarantor shall affect, impair, or be a defense to this 
Guaranty. Each of the persons who has signed this or any other Guaranty has 
unconditionally delivered it to Lender, and the failure to sign this or any 
other Guaranty by any other person shall not discharge the liability of any 
signer. The unconditional liability of the signer applies whether the signer is 
jointly and severally liable for the entire amount of the debt, or for only a 
pro-rata portion.

        11.     Choice of Law and Forum.   THIS GUARANTY SHALL IN ALL RESPECTS 
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF 
CALIFORNIA, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE AND

various equipment leases between (a) GE and CuraCare and (b) GE and AS-C (the

1994 (collectively the "Security Agreements") have granted to GE a lien and

and make advances to Debtor.

         C. GE has been requested by Debtor to provide Debtor with an additional
loan, secured by certain collateral, more particularly described as the

                 2. Relative Priorities relating to Accounts Receivable
Collateral.

                          (a) The parties agree at all times, whether before,
during or after the pendency of any bankruptcy, reorganization or other
insolvency proceeding, and notwithstanding the time of granting or of perfection
of any security interest or lien or the time of filing or of recording of any
financing statements or any other documents, instruments or agreements under the
UCC or any other applicable law and as relates only to DVIBC Debt (i) DVIBC
shall have a first priority lien upon and security interest in the Accounts
Receivable Collateral superior to GE's security interest therein, and any
security interest of GE therein, whether now existing or hereafter acquired,
shall be subordinate to DVIBC's security interest therein; and (ii) each of GE
and DVIFS shall have a second and junior lien upon and security interest in the
Accounts Receivable Collateral ranking equally in priority.

                          (b) In the event that either of DVIBC or DVIFS elects
to accelerate any or all of Debtor's obligations pursuant to the DVI Debt, DVI
shall, forthwith upon such acceleration, notify GE in writing of such election
and the date thereof. In the event that GE elects to accelerate any or all of
Debtor's obligations pursuant to the GE Affected Debt, GE shall, forthwith upon
such acceleration, notify DVI in writing of such election and the date thereof.
The failure of either party to give the notice required by this section 2(b)
shall not affect the validity of the acceleration of the indebtedness with
respect to Debtor or create any claim or right on behalf of any third party. The
sending of such notice by either party shall not impose on the recipient thereof
any obligation to cure any default or Event of Default.

                          (c) GE and DVIFS (as related only to DVIFS Debt) shall
share in equal amounts and on an equal basis (pari passu) in all Second Lien
Liquidation Proceeds, if any, from any Liquidation of Accounts Receivable
Collateral.

                          (d) Irrespective of whether any Event of Default shall
have occurred under any agreements evidencing the DVI Debt or the GE Debt, and
notwithstanding any provisions of the UCC, so long as any DVI Debt remains
unpaid, and DVIBC retains a security interest in the Accounts Receivable
Collateral, GE shall not take 

                                       4
<PAGE>   5

any action to foreclose or realize upon or enforce any of its rights with
respect to the Accounts Receivable Collateral, including but not limited to,
notifying any account debtor, without the prior written consent of DVI, and
shall hold all Accounts Receivable Collateral and proceeds thereof, which may
come into GE's possession in trust for DVI, and shall turn over any such
collateral to DVI upon request. This provision does not limit GE's exercise of
any rights and remedies it may have under the GE Leases.

                 3. Relative Priorities Relating to UCSF Gamma Knife.

                          (a) The parties agree, at all times, whether before,
during or after the pendency of any bankruptcy, reorganization or other
insolvency proceeding, and notwithstanding the time of granting or of perfection
of any security interest or lien or the time of filing or of recording of any
financing statements or any other documents, instruments or agreements under the
UCC or any other applicable law that GE shall have a first priority lien upon
and security interest in the UCSF Gamma Knife superior to DVI's security
interest therein, and any security interest of DVI therein, whether now existing
or hereafter acquired, shall be subordinate to GE's security interest therein.

                          (b) Irrespective of whether any Event of Default shall
have occurred under the terms of any agreements evidencing the GE Debt or the
DVI Debt, and notwithstanding any provisions of the UCC, so long as any of the
GE Debt remains unpaid, and GE retains a security interest in the UCSF Gamma
Knife, DVI shall not take any action to foreclose or realize upon or enforce any
of its rights with respect to the UCSF Gamma Knife without the prior written
consent of GE, and shall hold all collateral and proceeds thereof, which may
come into DVI's possession in trust for GE, and shall turn over any such
proceeds to GE upon request.

                          (c) All proceeds realized from any disposition of the
UCSF Gamma Knife shall be allocated between, and shared by, GE and DVI in
conformity with their respective lien priorities.

                  4. Waivers and Consents. DVI and GE, and each of them, may at
any time, and from time to time, without notice to, or consent of the other
party, and without affecting or impairing 


                                       5
<PAGE>   6

the priority, subordination, rights and obligations under this Agreement, do any
of the following:

to the DVI Debt) renew or extend any DVI Debt or GE Debt respectively;

                          (b) Accept partial payment of any DVI Debt or GE Debt,

                          (d) Consent to the transfer or sale of any collateral
securing any DVI Debt or GE Debt, respectively; or

                          (e) Bid and purchase at any sale of any sale of any
collateral securing any DVI Debt or GE Debt, respectively.

                          (f) Except for the notices required by Section 2(b) of
this Agreement, DVI and GE, and each of them, waive all notices, protests and
demands, including, but not limited to, notice of (i) default or (ii) payment or
in performance or observance of any of the terms, provisions, covenants or
conditions contained in any agreement or instrument with Debtor evidencing any
senior DVI Debt or senior GE Debt, respectively.

                          (g) DVI and GE, and each of them, agree that the
validity of this Agreement and the subordination, priority, rights and
obligations of DVI and GE, and each of them, shall not be terminated, affected
or impaired by reason of the waiving, delaying, exercising or non-exercising of
either party's rights relating to its debt or as a result of the substitution,
release, repossession, sale, disposition or destruction of any collateral, or by
either party's failure or delay to perfect or continue the perfection of any
security interest in any Collateral or to perfect the Collateral securing the
indebtedness owed to either party by Debtor.

                          (h) DVIBC may at any time, and from time to time,
without notice to, or consent of GE, and without affecting or impairing the
priority, subordination, rights and obligations 

                                       6
<PAGE>   7

under this Agreement, and with respect to the DVIBC Debt only, subject to the
limitations set forth in Section 1(c) above, increase or reduce the amount of
the DVIBC Debt, modify any formula or requirements for determining Eligible
Accounts, modify the Net Collectible Value or Net Collectible Percentage of the
Accounts, and modify the amounts of, and formula for determining, Advances and
Advance Percentages. All capitalized terms in this Subsection 4(h) shall have
the meanings set forth in the Loan Agreement between DVIBC and Debtor.

                  5. Debtor Repayment. GE hereby agrees that, at any time a
payment with respect to the GE Debt is made thereto by Debtor and DVI has
provided written notice to GE within thirty (30) days of such payment that
amounts are then due and payable to DVI under the DVI Debt, GE shall pay over to
DVI the amount then due and payable to DVI pursuant to the DVI Debt (including
any balloon payments but excluding any amounts which have been accelerated by
DVI), in each case as of the date of receipt of such notice by GE, provided,
however, that any such payment by GE to DVI shall not exceed the amount of such
payment by Debtor to GE. Debtor acknowledges that any such payment by GE to DVI
will be deemed to reduce the amount of any such payment by Debtor with respect
to such portion of the Affected GE Debt, as determined by GE, and that Debtor
will therefore be in default with respect to such Affected GE Debt. Debtor
agrees, on the date of payment, to notify DVI in writing of the date and amount
of any payment made to GE with respect to the GE Debt.

                  6. Parties Intended to be Benefitted. All of the
understandings, covenants and agreements contained herein are solely for the
benefit of DVI and GE, and there are no other parties (including Debtor or any
of its creditors, successors or assigns) which are intended to be benefitted, in
any way, by this Agreement.

                  7. No Limitation Intended. Nothing contained in this Agreement
is intended to or shall affect or limit, in any way, the rights that DVI and GE
have with respect to Debtor or any third parties pursuant to any written
agreement or otherwise. DVI and GE hereby specifically reserve all of their
respective rights against Debtor and all other third parties. DVI shall be
entitled to deal with Debtor free from interference by GE, and GE shall be
entitled to deal with Debtor free from interference by DVI. Nothing contained in
this Agreement, nor any action taken 

                                       7
<PAGE>   8

by any of the parties hereto, is intended to constitute or shall be deemed to
constitute DVI and GE as a partnership, association, joint venture or other
entity.

                  8. Waiver of Marshalling. GE specifically waives and renounces
any right, under any applicable law, including California Civil Code Section
3433 or any analogous statute, which it may have, whether at law or in equity,
to require DVI to marshall the collateral unless it has been granted a security
interest by Debtor, or any portion thereof, or to otherwise seek satisfaction
from any particular assets of Debtor or from any third party.

                  9. Term. This Agreement shall have a term expiring upon the
later of (a) the repayment, performance and satisfaction in full of the DVI Debt
and the release by DVIBC and DVIFS of their respective security interests in the
Accounts Receivable Collateral, or (b) the repayment, performance and
satisfaction in full of the GE Debt and the release by GE of its respective
security interest in the UCSF Gamma Knife.

concerning the matter in question that would cause such reliance to be 
unwarranted:

Manager reasonably believes to be reliable and competent in the matters
presented;

              (b) any attorney, public accountant, or other person as to matters

care as an ordinarily prudent person in a like position would use under similar
circumstances, and in accordance with the Articles, this Agreement and
applicable law. A Person who so performs its duties shall not have any liability
by reason of being or having been a Manager of Company.

         Manager shall maintain a separate capital account (a "Capital Account")
for each Member in accordance with the requirements of Regulations Section
1.704-1(b)(2)(iv). To the extent that the results determined under any provision
of this Article IV vary from the results that would be required under the rules
described in Regulations Section 1.704-1(b)(2)(iv), the rules set forth in
Regulations Section 1.704-1(b)(2)(iv) shall be used and govern the maintenance
of Capital Accounts under the Agreement.

4.2           RESERVED

4.3           CAPITAL ACCOUNT MAINTENANCE

         Subject to the other Paragraphs of this Article, the Capital Account of
any Member shall be maintained for such Member in accordance with the following
provisions:

         A. To each Member's Capital Account there shall be credited the amount
of cash contributed by such Member, the initial Gross Asset Value of any
property contributed by such Member, such Member's distributive share of Net
Profits and any items in the nature of income or gains which are specially
allocated, and the amount of any liabilities of Company assumed by the Member or
which are secured by any property distributed to the Member.

         B. To each Capital Account there shall be debited the amount of cash
and the Gross Asset Value of any property distributed to the Member pursuant to
any provision of the Agreement, the Member's distributive share of Net Losses
and any items in the nature of expenses or losses which are specially allocated,
and the amount of any liabilities of the Member assumed by Company or which are
secured by any property contributed by the Member to Company.

         C. In the event all or a portion of a Membership Interest is
transferred in accordance with the terms of the

                                       30


<PAGE>   32

Agreement, the transferee shall succeed to the Capital Account of the transferor
to the extent it relates to the transferred interest.

         D. In the event that assets of Company other than cash are distributed
in kind to a Member, Capital Accounts shall be adjusted for the hypothetical
"book" gain or loss that would have been realized by Company if the distributed
assets had been sold for their fair market values in a cash sale (in order to
reflect unrealized gain or loss).

4.4           DEFINITIONS USED IN CAPITAL ACCOUNT MAINTENANCE

         A.   "Gross Asset Value" means, with respect to any asset, the asset's
adjusted basis for federal income tax purposes, except as follows:

              a. The initial Gross Asset Value of any asset contributed by a
Member to Company shall, except as otherwise provided in Section 2.3 hereof in
relation to Gamma Knife units, be the gross fair market value of such asset, as
determined by the Policy Committee.

              b. The Gross Asset Values of all assets of Company shall be
adjusted to equal their respective gross fair market values, as determined by
the Policy Committee, as of the following times: (i) the acquisition of an
additional Interest by any new or existing Member in exchange for more than a de
minimis Capital Contribution; (ii) the distribution by Company to a Member of
more than a de minimis amount of property as consideration for an Interest; and
(iii) the liquidation of Company within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g); provided, however, that adjustments pursuant to clauses
(i) and (ii) above shall be made only if the Policy Committee reasonably
determines that such adjustments are necessary or appropriate to reflect the
relative economic interests of the Members in Company.

              c. The Gross Asset Value of any asset of Company distributed to
any Member shall be adjusted to equal the gross fair market value of such asset
on the date of Distribution, as determined by the distributee and the Manager,
provided that, if

                                       31


<PAGE>   33

the distributee is a Manager, the determination of the fair market value of the
distributed asset shall require the consent of the non-distributee Members; or
if the parties cannot agree, an appraiser mutually acceptable to both parties
shall be selected to determine the Gross Asset Value of such asset.

              d. The Gross Asset Values of assets of Company shall be increased
(or decreased) to reflect any adjustments to the adjusted basis of such assets
pursuant to Code Section 734(b) or Code Section 743(b), but only to the extent
that such adjustments are taken into account in determining Capital Accounts
pursuant to Regulations Section 1.704-1(b)(2)(iv)(m); provided, however, that
Gross Asset Values shall not be adjusted pursuant to this Subparagraph to the
extent the Manager determines that an adjustment pursuant to Subparagraph
4.4.A.b above is necessary or appropriate in connection with a transaction that
would otherwise result in an adjustment pursuant to this Subparagraph.

              e. If the Gross Asset Value of an asset has been determined or
adjusted pursuant to any of the Subparagraphs above, such Gross Asset Value
shall thereafter be adjusted by the Depreciation taken into account with respect
to such asset and shall be utilized for purposes of computing Net Profits and
Net Losses.

         B.   "Net Profits" and "Net Losses" shall have the meanings set forth
in Subparagraph 5.2.G.

4.5           POWER TO MODIFY CAPITAL ACCOUNTS TO COMPLY WITH REGULATIONS

         The foregoing provisions and the other provisions of the Agreement
relating to the maintenance of Capital Accounts are intended to comply with
Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner
consistent with such Regulations. In the event the Policy Committee determines
that it is necessary to modify the manner in which the Capital Accounts are
computed in order to comply with such Regulations and to reflect the agreed upon
sharing of the distribution of cash, the Policy Committee may make such
modification, provided that it is not likely to have a material effect on the
amounts

                                       32


<PAGE>   34



distributable to any Member upon the dissolution of Company. The Policy
Committee also shall make any appropriate modifications in the event
unanticipated events occur that might otherwise cause the Agreement not to
comply with Regulations Section 1.704-1(b).

                                    ARTICLE V

           ALLOCATIONS OF NET PROFITS AND NET LOSSES AND DISTRIBUTIONS

5.1           ALLOCATIONS OF NET PROFITS AND NET LOSSES

         A.   General Allocations of Net Profits and Net Losses

              After giving effect to the special allocations set forth elsewhere
herein, Net Profits and Net Losses for any fiscal year of the Company shall 
be allocated as follows:

              (I)   Allocation of Net Profits

                    Net Profits for any fiscal year shall be allocated to each
Member in accordance with its Percentage Interest.

              (II)  Allocation of Net Losses

                    Net Losses for any fiscal year shall be allocated to each
Member in accordance with its Percentage Interest.

         B.   Certain Special Allocations

              The following special allocations shall be made in the following
order:

              (I)   Company Minimum Gain Chargeback

                    If there is a net decrease in Company Minimum Gain for a
Company taxable year, then each Member shall be allocated items of income and
gain for such year (and, if necessary, for subsequent years) in the manner and
to the extent required by Regulations Section 1.704-2(f).

                                       33


<PAGE>   35



              (II)  Member Minimum Gain Chargeback

                    If there is a net decrease during a Company fiscal year in
Member Minimum Gain, then any Member with a share of Member Minimum Gain
(determined under Regulations Section 1.704-2(i)(5)) at the beginning of such
year shall be allocated items of Company income and gain for such year (and, if
necessary, subsequent years) in the manner and to the extent required by
Regulations Section 1.704-2(i)(4).

              (III) Qualified Income Offset

                    Any Member who unexpectedly receives an adjustment,
allocation or distribution described in Regulations Section 1.704-1(b)(2)(ii)
(d)(4), (5), or (6) will be allocated items of income and gain (consisting 
of a pro rata portion of each item of Company income, including gross income 
and gain, for such year) in an amount and manner sufficient to eliminate 
any Adjusted Capital Account Deficit as quickly as possible, provided that 
such allocation shall be made if and only to the extent such Member would
have an Adjusted Capital Account Deficit after all other allocations pursuant 
to this Subparagraph 5.1.B have been made tentatively as if this Subparagraph
5.1.B(III) were not in the Agreement.

              (IV)  Gross Income Allocation

                    In the event any Member has a deficit Capital Account at the
end of any Company fiscal year which is in excess of the sum of (i) the amount
such Member is obligated to restore, and (ii) the amount such Member is deemed
to be obligated to restore pursuant to the penultimate sentences of Regulations
Section 1.704-2(g)(1) and Section 1.704-2(i)(5), each such Member shall be
specially allocated items of Company income and gain in the amount of such
excess as quickly as possible, provided that any allocation pursuant to this
Subparagraph 5.1.B(IV) shall be made if and only to the extent that such Member
would have a deficit Capital Account in excess of such sum after all other
allocations provided for in this Subparagraph 5.1.B have been tentatively made
as if this Subparagraph 5.1.B(IV) and Subparagraph 5.1.B(III) were not in the
Agreement.

                                       34


<PAGE>   36


              (V)   Allocation of Nonrecourse Deductions

                    Member Nonrecourse Deductions shall be allocated to the
Member, if any, that bears the economic risk of loss for the Member Nonrecourse
Debt to which the Member Nonrecourse Deductions are attributable in accordance
with Regulations Section 1.704-2(i)(1). Company Nonrecourse Deductions shall be
allocated in the same manner as Net Profits.

              (VI)  Syndication Expenses

                    In the event that additional Members are admitted to the
Company on different dates, all syndication expenses shall be divided among the
persons who are Members from time to time so that, to the extent possible, the
cumulative amount of syndication expenses allocated with respect to each Member
at any time is in proportion to that Member's Percentage Interest as determined
after such admission. In the event the Manager shall determine that such result
is not likely to be achieved through future allocations of syndication expenses,
the Manager may allocate other items of income, gain, deduction or loss so as to
achieve the same effect on the Capital Accounts of the Members.

         C.   Certain Other Allocation Rules

              (I)   Allocation of Income, Gains and Losses Related to 
                    Contributed Property

                    In accordance with Code Section 704(c) and the Regulations
thereunder, income, gain, loss, and deduction with respect to any property
contributed to the capital of Company shall, solely for tax purposes, be
allocated among the Members so as to take account of any variation between the
adjusted basis of such property to Company for federal income tax purposes and
its Gross Asset Value. In the event the Gross Asset Value of any Company asset
is adjusted pursuant to the provisions of this Agreement, subsequent allocations
of income, gain, loss, and deduction with respect to such asset shall take
account of any variation between the adjusted basis of such asset for federal
income tax purposes and its Gross Asset Value in the same manner as under Code
Section 704(c) and the Regulations

                                       35


<PAGE>   37

thereunder. Any elections or other decisions relating to such allocations shall
be made by the Policy Committee in any manner permitted by the Regulations that
reasonably reflects the purpose and intention of the Agreement. Unless the
Policy Committee determines otherwise, the method of allocation with respect to
each item of contributed property shall be chosen in a manner that results in
the greatest allocation of depreciation or amortization with respect to such
item of property to the Members other than the Member that contributed such item
of property. Allocations pursuant to this Subparagraph are solely for purposes
of federal, state, and local taxes and shall not affect, or in any way be taken
into account in computing, any member's Capital Account or share of Net Profits,
Net Losses, or other items or distributions pursuant to any other provision of
the Agreement.

              (III) Allocations to Avoid Adjusted Capital Account Deficit

                    Notwithstanding any other provision of this Article, no
Member shall receive an allocation of Net Losses or any other item of loss or
deduction that would create or increase an Adjusted Capital Account Deficit of
the Member. Any Net Loss, or item thereof, that cannot be allocated to a Member
as a result of the foregoing limitation shall be allocated to all Members who do
not have an Adjusted Capital Account Deficit. Any Net Loss, or item thereof,
allocated to Members pursuant to the preceding sentence shall be taken into
account in computing subsequent allocations of Net Profits so that the net
amount of any items so allocated to each Member shall, to the extent possible,
be equal to the net amount that would have been allocated to each Member if the
allocations required by the preceding sentence had not been made.

              (IV)  Excess Nonrecourse Liabilities

                    Solely for purposes of determining a Member's proportionate
share of the "excess nonrecourse liabilities" of the Company within the meaning
of Regulations Section 1.752-3(a)(3), the Member's interests in the Company
equal their respective Percentage Interests determined from time to time.

             (V)  Allocation of Net Profits and Losses and Distributions in
Respect of a Transferred Interest

                  If any Interest is transferred, or is increased or decreased
by reason of the admission of a new Member or otherwise, during any fiscal year
of Company, each item of income, gain, loss, deduction, or credit of Company for
such fiscal year shall be allocated to the Members based upon the pro rata
method, except that any gain or loss of Company realized in connection with a
sale or other disposition of any of the assets of Company shall be allocated
solely to the parties owning Interests in Company as of the date such sale or
other disposition occurs.

             (VI) Curative Allocations

                  The allocations set forth in Subparagraph 5.1.B hereof (the
"Regulatory Allocations") are intended to comply with certain requirements in
the Regulations. It is the intent of the Members that, to the extent possible,
all Regulatory Allocations shall be offset either with other Regulatory
Allocations or with special allocations of other items of Company income, gain,
loss or deduction pursuant to this Subparagraph 5.1.C(VI). Therefore,
notwithstanding any other provisions of this Agreement (other than the
Regulatory Allocations), the Manager shall make such offsetting special
allocations of Company income gain, loss or deduction in whatever manner the
Manager determines appropriate so that, after such offsetting allocations are
made, each Member's Capital Account balance is, to the extent possible, equal to
the Capital Account balance such Member would have had if the Regulatory
Allocations were not part of this Agreement and all Company items were
located pursuant to Subparagraph 5.1.A. In exercising its discretion
hereunder, the Manager shall take into account any future Regulatory Allocations
that are likely to offset other Regulatory Allocations previously made.

5.2          DEFINITIONS OF TECHNICAL TERMS USED FOR ALLOCATION PURPOSES

recovery deduction allowable with respect to an asset for such year or other
period, except that, if the Gross Asset Value of an asset differs from its
adjusted basis for federal income tax purposes at the beginning of such year or

beginning Gross Asset Value as the federal income tax depreciation,
amortization, or other cost recovery deduction for such year or other period
bears to such beginning adjusted tax basis; provided, that if the adjusted basis
for federal income tax purposes of an asset at the beginning of such fiscal year

                       CONSEQUENCES OF DEATH, DISSOLUTION,
                       RETIREMENT OR BANKRUPTCY OF MEMBER

7.1                       CONSENT TO CONTINUE BUSINESS OF COMPANY

                 Upon the occurrence of any Dissolution Event, Company shall
dissolve unless the remaining Members holding a Majority-In-Interest consent to
the continuation of the business of Company. A Member whose actions or conduct
result in the Dissolution Event is referred to herein as the "Former Member".

7.2                       PURCHASE OF MEMBER'S INTEREST

                 Upon the occurrence of any Dissolution Event specified in
Subparagraph 9.1(iii) and the consent of the remaining Members holding a
Majority-In-Interest (excluding for this purpose the Membership Interest of the
Former Member) to continue the business of Company, the other Members (the
"Remaining Members") shall have an option to purchase the Former Member's
Membership Interest. Within ninety (90) days of such consent, or


                                       44

<PAGE>   46



within ninety (90) days of the inheritance or transfer by operation of law to a
person of the Former Member's Membership Interest, the Remaining Members shall
notify the Manager in writing of their desires to purchase a portion of the
Former Member's Interest.

7.3                 FAILURE TO SUBMIT NOTICE OF PURCHASE

                 The failure of any Remaining Member to submit a notice within
the applicable period shall constitute an election on the part of the Member not
to purchase any of the Former Member's Interest. Each Remaining Member shall be
entitled to purchase a portion of the Former Member's Interest on a pro rata
basis based on the Remaining Member's Percentage of Interest on the date of the
consent referred to in Paragraph 7.2 hereof.

7.4                 ELECTION TO PURCHASE LESS THAN ALL OF AN INTEREST

                 In the event any Remaining Member elects to purchase none or
less than all of its pro rata part of the Former Member's Interest, then, at its
election, those Remaining Members can elect to purchase more than their pro rata
part, i.e., the proportion that the Percentage Interest of the Former Member
bears to the aggregate of the Percentage Interests of all Members and the Former
Member. If the Remaining Members fail to purchase the entire interest of the
Former Member, Company may elect to purchase the unpurchased portion of the
Former Member's Interest. If none of the above elects to purchase, the same
shall pass by operation of law to any assignee or shall remain in the hands of
the Former Member. Notwithstanding any provision of the Agreement to the
contrary, the remaining Members may mutually agree to an allocation of the
Former Member's Interest to be purchased by each of them.

7.5                 VALUATION OF INTEREST OF MEMBER

                 The Former Member's Interest shall be valued according to its
book value determined in accordance with generally accepted accounting
principles, provided, however, if the Former Member or such Former Member's
trustee or heirs or any Remaining Member electing to purchase or Company if it
elects to purchase, deems the book value to vary from fair market value by more
than 


                                       45
<PAGE>   47


five percent (5%), such person shall be entitled to require an appraisal. In
such event, the value of the Former Member's Interest shall equal the fair
market value of the Interest as determined by agreement within ninety (90) days
after the notice to remaining Members or, in case of a failure to agree within
such ninety (90) day period, as determined by three appraisers, one selected by
the Former Member or such Former Member's trustee(s) or heir(s), one selected by
the Remaining Member, and one selected by the two appraisers so named. All
appraisers appointed under this Paragraph 7.5 shall be generally known and
respected with respect to appraisals in the Company's industry. The fair market
value of the Former Member's interest in Company shall be the average of the two
appraisals closest in amount to each other except that if one appraisal is equal
to the average of all three appraisals, the fair market value shall be equal to
such average. In the event the fair market value is determined to be within five
percent (5%) of book value, the party requesting such appraisal shall pay all
expense of the same otherwise incurred by the parties offering to enter into the
transaction at the book valuation. In the event the fair market value is
determined not to be within five percent (5%) of book value, the expense of such
appraisal shall be paid by the Company.

7.6                 PAYMENT OF PURCHASE PRICE

                 The purchase price shall be paid by Company or the Remaining
Member, as the case may be, within 60 days after the determination of the fair
market value of the Former Member's Interest in Company as provided herein.

7.7                 PURCHASE TERMS VARIED BY AGREEMENT

                 Nothing contained herein is intended to prohibit Members from
agreeing upon terms and conditions for the purchase by Company or any Member of
the Interest of any Member in Company desiring to retire, withdraw or resign, in
whole or in part, as a Member (on such terms and conditions as may be agreed
upon by the selling Member and Company or the remaining Members as the case may
be), nor is anything herein intended to limit or otherwise affect the ability of
a Member to demand a return of his or its contribution to Company as may be
required in the Act.

satisfactory to Company that registration under such laws is not required; or
(ii) if the Interest to be sold or exchanged, when added to the total of all
other Interests sold or exchanged in the preceding twelve (12) consecutive
months prior thereto, would result in the termination of Company under Code
Section 708.

8.3                 SUBSTITUTION OF MEMBERS AFTER TRANSFER OF INTEREST

                 Notwithstanding anything herein to the contrary, a transferee

absolute discretion of each Member), (ii) the requirements of Paragraph 8.2
relating to securities and tax requirements hereof are met, (which approval may
be granted, delayed or withheld in their sole and absolute discretion), (iii)
such Person executes an instrument satisfactory to the Remaining Members
accepting and adopting the terms and provisions of the Agreement, and (iv) such
Person pays any reasonable expenses in connection with his or her admission as a
new Member. An assignee who becomes a substituted Member has, to the extent

Management and Voting Rights or Information Rights. Until the assignee of an

Agreement; provided that this Subparagraph (vii) shall become void and of no
further effect on the day on which the Company receives an equity capital
contribution from a Member that is not ASRS or GKV; or

                 (viii)   If the Policy Committee is unable to attain a

9.2                 STATEMENT OF INTENT TO DISSOLVE

                 As soon as possible following the occurrence of any of the
events specified in Paragraph 9.1, the Manager on behalf of Company shall file a
certificate of dissolution and form prescribed by the Secretary of State as
required by the Act. The Manager shall deliver two signed copies of the

on its business, except insofar as may be necessary for the winding up of its
business, but its separate existence continues until the certificate of
cancellation of articles of organization has been filed with the Secretary of
State or until a decree dissolving the company has been entered by a court of
competent jurisdiction.

9.3                 WINDING UP

                 Upon the occurrence of any of the events specified in Paragraph
9.1, Company shall continue solely for the purpose of winding up its affairs in
an orderly manner, liquidating its assets, disposing of and conveying its
property, collecting and dividing its assets, satisfying the claims of its
creditors and prescribing and defending actions by or against Company in order
to collect and discharge obligations. No Member shall take any action that is
inconsistent with, or not necessary to or appropriate for, winding up the
business and affairs of Company. To the extent not inconsistent with the
foregoing, all covenants and obligations in the Agreement shall continue in full
force and effect until such time as the assets have been distributed and Company
has terminated. If any Member receives a distribution in kind such item or items
shall be deemed to have been sold for fair market value, and Capital Accounts
shall be adjusted to reflect deemed gain or loss on each such transaction. Upon
the filing of the Statement of Intent to Dissolve, the following shall occur:

     A.           ASRS shall have the right (but not the obligation) to purchase
from the Company either or both of the Company's Gamma Knife projects (including
all physical assets and all intangible assets associated with such projects)
located at the USC University Hospital and at the University of California San
Francisco Hospital previously transferred by ASRS to the Company. At the time 
of such transfer(s), if any, ASRS shall pay to the Company cash in an amount 
equal to the fair market value of such transferred assets as of the time of 
transfer.

     B.           GKV shall have the right and obligation to purchase from the 
Company the rights of the Company under the LGK Purchase Agreement relating to
each Gamma Knife for which the Company has not entered into an alternative
financing agreement with an end-


                                       50
<PAGE>   52


user (and each such Gamma Knife if title thereto shall have passed to the
Company), and the consideration for such rights shall consist of: (i) the
assumption by GKV of all of the Company's obligations under the LGK Purchase
Agreement relating to each such Gamma Knife; and (ii) a cash amount equal to any
advance payments theretofore actually paid by the Company to EII and/or its
Affiliates in relation to Gamma Knife units ordered by the Company but for which
no alternative financing agreement has been entered by the Company with an
end-user. However, GKV shall have the right to offset such cash payment against
the then outstanding principal and accrued interest under the GKV Loan and/or
the Draw Down Loan, whether or not such principal or accrued interest is then
payable.

C.                In addition, the Members shall have the option to acquire the 
rights of the Company to other existing alternative financing agreements with
end-users relating to Gamma Knives (which shall include any Gamma Knife related
thereto) and other assets by paying to the Company cash in an amount equal to
the fair market value of such transferred assets. Such fair market value shall
be determined in accordance with the procedures described in Subparagraph
2.1.B.2. In the event more than one Member desires to exercise such right, such
rights shall be exercised by the Members as closely as practicable in proportion
to their Percentage Interests.

9.4                 RESPONSIBILITIES FOR WINDING UP

                 The Manager shall be responsible and be compensated for
overseeing the winding up and liquidation of Company, shall take full account of
the liabilities of Company and assets, shall cause its assets to be liquidated
as promptly as is consistent with obtaining the fair market value thereof, and
shall cause the proceeds therefrom, to the extent sufficient therefor, to be
applied and distributed as next provided. The persons responsible for winding up
the affairs of Company shall give written notice of the commencement of winding
up by mail for all known creditors and claimants whose addresses appear on the
records of Company.

9.5                 ORDER OF PAYMENT UPON DISSOLUTION

                 In settling accounts of Company after dissolution, the Manager
shall settle the liabilities of Company with payments in the following order, as
required by the Act:

                 (i)      To creditors, including Members, in the order of 
priority as provided by law, except those to Members of Company on account of
their contributions;

                 (ii)     To Members of Company in accordance with the 
respective positive Capital Account balances after giving effect to all Capital
Contributions, distributions, revaluations and allocations required under this
Agreement, in an amount equal to the sum of such positive Capital Account
balances; and

                 (iii)    Any remaining assets shall be distributed to the 
members in proportion to their Percentage Interests.

9.6                 COMPLIANCE WITH REGULATIONS

                 All distributions to the Members upon the winding up and
dissolution of Company shall be strictly in accordance with the positive Capital
Account balance limitation and other requirements of Regulations Section
1.704-1(b)(2)(ii)(d), provided however that no Member shall be required to
restore a negative balance in its Capital Account upon dissolution of Company.

9.7                 LIMITATIONS ON PAYMENTS MADE IN DISSOLUTION

                 Except as otherwise specifically provided in the Agreement,
each Member shall only be entitled to look solely at the assets of Company for
the return of his positive Capital Account balance. The Manager shall be
entitled to reasonable compensation for winding up the affairs of the Company.

10.1                INDEMNIFICATION OF MEMBERS AND MANAGER

                 Company shall indemnify against expenses and liabilities any
Member, Manager or Officer made a party or who was threatened to be made a party
to any proceeding by Company or another because such party is or was a Member,
Manager or Officer, as a matter of right, against all liability incurred by such
individual in connection with any action, suit, or proceeding or any threatened,
pending or complete action, suit or proceeding; whether civil, criminal,
administrative, or investigative provided that it shall be determined in the
specific case in accordance with Paragraph 10.5 of this Article X that
indemnification of such individual is permissible in the circumstances because
the individual has met the standard of conduct for indemnification set forth in
this Article X.

10.2                ADVANCE UNDERTAKINGS FOR INDEMNIFICATION

                 Company shall pay for or reimburse the reasonable expenses
incurred by a Member, Manager or Officer in connection with any such proceeding
as incurred in advance of final disposition of the action, suit, or proceeding
thereof if (i) the person furnishes Company a written affirmation of the
person's good faith belief that it has met the standard of conduct for
indemnification described in Paragraph 10.5, (ii) the person furnishes Company a
written undertaking, executed personally or on such person's behalf, to repay
the advance if it is ultimately determined by a court of competent jurisdiction
that such person did not meet such standard of conduct and that it is not
entitled to be indemnified, and (iii) a determination is made in accordance with
Paragraph 10.6 that based upon facts then known to those making the
determination, indemnification would not be precluded under this Article.

                 The undertaking described above must be a general obligation of
the individual, subject to such reasonable limitations as Company may permit,
but need not be secured and may be accepted without reference to financial
ability to make 


                                       53
<PAGE>   55


repayment. Company shall indemnify a Member, Manager or Officer
who is wholly successful, on the merits or otherwise, in the defense of any such
proceeding, as a matter of right, against reasonable expenses incurred by the
person in connection with the proceeding without the requirement of a
determination as set forth in Paragraph 10.6.

10.3                ADVANCEMENT OF EXPENSES

                 Upon demand by a Member, Manager or Officer for indemnification
or advancement of expenses incurred in defending a civil or criminal suit or
proceeding, as the case may be, Company shall expeditiously determine whether
the Member, Manager or Officer is entitled thereto in accordance with this
Article X.

10.4                INDEMNIFICATION OF OTHERS

                 Company shall be empowered, but shall not be obligated, to
indemnify any individual who is or was an employee or agent of Company to the
same extent as if such individual were a Member, Manager or Officer. Such
indemnification shall occur only after unanimous approval by the Policy
Committee.

10.5                STANDARDS OF CONDUCT FOR INDEMNIFICATION

                 Indemnification of a Manager, Member or Officer is permissible
under this Article X only if (i) such person conducted itself in good faith and
within the scope of authority granted by the Policy Committee, and (ii)
reasonably believed that its conduct was in or at least not opposed to Company's
best interest; and (iii) in the case of any criminal proceeding, it had no
reasonable cause to believe its conduct was unlawful. The termination of a
proceeding by judgment, order, settlement, conviction or upon a plea of nolo
contendere or its equivalent is not, of itself, determinative that the person
did not meet the standard of conduct described in this Paragraph 10.5.

Loan into a capital contribution, the Percentage Interests of the Members shall
be adjusted in the manner described in Subparagraph 2.1.B hereof.

that the UCSF Contract, the UCSF Lease, the USC Contract and the USC Lease are
in full force and effect and neither party to each such contract or lease is in
breach thereof and that ASRS has heretofore delivered to GKV true, correct and
complete copies of all such contracts and leases.

(6)              ASRS hereby represents and warrants to the Company and to GKV 
that there is no suit, action, claim or investigation pending or threatened
against, affecting or relating to or arising from the UCSF Assets or the USC
Assets, and there exists no basis or grounds for same.

less direct cash operating expenses) generated by the UCSF Assets or the USC
Assets, is insufficient to service the lease payments under the UCSF Lease or
