U. S. NeuroSurgical, Inc.
FO
General

      USN, was organized in July 1993 to own and operate stereotactic
radiosurgery centers, utilizing the Gamma Knife technology. USN currently owns
and operates two


                                       2
<PAGE>

Gamma Knife centers, one on the premises of Research Medical Center (RMC) in
Kansas City, Missouri, and one on the premises of New York University Medical
Center (NYU) in New York, New York. The Company, intends to continue to explore
opportunities to open additional Gamma Knife Centers. USN's business strategy is
to provide a mechanism whereby hospitals, physicians, and patients can have
access to Gamma Knife treatment capability, a high capital cost item. USN
provides the Gamma Knife to medical facilities on a "cost per treatment" basis.
USN owns the Gamma Knife units, and is reimbursed by the facility where it is
housed, based on utilization.

      USN's principal target market is medical centers in major health care
catchment areas that have physicians experienced with and dedicated to the use
of the Gamma Knife. As it has with its RMC and NYU Gamma Knife centers, USN
would seek cooperative ventures with these facilities if it were to explore
opening additional centers. USN believes that, as of December 31, 2000, there
were approximately 50 Gamma Knife treatment centers in the United States.

Gamma Knife Technology

      The Leksell Gamma Knife is a unique stereotactic radiosurgical device used
to treat brain tumors and other malformations of the brain without invasive
surgery. The Gamma Knife delivers a single, high dose of ionizing radiation
emanating from 201 cobalt-60 sources positioned about a hemispherical, precision
machined cavity. The lesion is first targeted with precision accuracy using
advanced imaging and three dimensional treatment planning techniques such as CT
Scans, MR Scans, conventional X-rays, or angiography. Each individual beam is
focused on a common target producing an intense concentration of radiation at
the target site, destroying the lesion while spreading the entry radiation dose
uniformly and harmlessly over the patient's skull . The mechanical precision at
the target site is +/- 0.1mm (1/10 of 1 millimeter). Because of the


                                       3
<PAGE>

steep fall-off in the radiation intensity surrounding the target, the lesion can
be destroyed, while sparing the surrounding tissue.

      The procedure, performed in a single treatment, sharply reduces hospital
stay times and eliminates post-surgical bleeding and infection. When compared
with conventional neurosurgery, Gamma Knife treatment is less expensive.
However, not all patients are candidates for radiosurgery since the decision to
use the Gamma Knife depends on the type, size, and location of the lesion.

      Kansas City and New York Centers

      In July 1993, USN purchased its first Leksell Gamma Knife from Elekta
Instruments, Inc. (Elekta), for the purpose of installing it at RMC in Kansas
City, Missouri. USN paid approximately $3,000,000 for the Gamma Knife through a
capital lease financing.

      USN opened its first Gamma Knife Center on the premises of RMC in
September 1994. RMC is part of Health Midwest, a consortium of eleven hospitals
and numerous affiliates. USN formed a cooperative venture with RMC in September,
1993. Per an agreement with RMC, GHS, Inc., USN's former parent, ("GHS") sold
500,000 shares of its common stock for $500,000 to RMC to secure additional
working capital in order to enable USN to develop and construct a Gamma Knife
Facility. USN installed the Gamma Knife in the facility, where it is being
utilized by neurosurgeons credentialled by RMC. USN is reimbursed for use of the
Gamma Knife by RMC based on a percentage of the fees collected by RMC for Gamma
Knife procedures. USN is responsible for the maintenance and insurance for the
Gamma Knife equipment at the RMC facility. Pursuant to a ground lease agreement,
RMC leased to USN the land on which to build the Gamma Knife facility. USN's
facility agreements with RMC expire in 2015 and there are no renewal options.
For the year ended December 31, 2000 and the fiscal years 1999 and 1998 USN
derived revenues from the RMC center of approximately $1,341,000,


                                       4
<PAGE>

$2,081,000 and $1,425,000, respectively, as a result of 116, 153 and 124
procedures performed, respectively, during such periods.

      USN opened its second treatment center in July 1997 on the campus of NYU
in New York, New York. Construction of the Gamma Knife suite was completed in
July 1997. The Gamma Knife cost and the cost of the facility improvements
totaled approximately $4,700,000. DVI Financial Services, Inc. (DVI) provided
the capital lease financing for the NYU facility. The lease term is six years
with incremental payments for the first year and fixed payments thereafter. The
interest rate for such capital lease is 12%. The Company has retained a
marketing representative to help introduce the technology to neurosurgeons in
the New York tri-state region. Pursuant to USN's facility agreement with NYU,
USN is responsible for the maintenance and insurance for the Gamma Knife
equipment at the NYU facility and is reimbursed for use of the Gamma Knife based
on a fee per procedure performed with the equipment. NYU provides the medical
and technical staff to operate the facility. USN's agreement with NYU expires in
November 2003 and NYU has options to renew the agreement for successive three
year periods thereafter. For the years ended December 31, 2000, 1999, and 1998,
USN derived revenues from the NYU center of approximately $1,207,000, $980,000,
and $890,000, respectively, as a result of 121, 98, and 89 procedures performed,
respectively, during such periods.

      In March 1997, USN refinanced the lease on the RMC Gamma Knife with DVI.
The effects of this transaction were to lower its interest costs to 10.4 % per
annum and provide proceeds to pay for the buildout of The NYU Gamma Knife suite.
USN also commenced loans with DVI for working capital of $188,000 to finance the
remainder of the buildout. These loans had three year terms and were paid off in
1999 and 2000.

Regulatory Environment

      The levels of revenues and profitability of companies involved in the
health services industry, such as USN, may be affected by the continuing efforts
of


                                       5
<PAGE>

governmental and third party payors to contain or reduce the costs of health
care through various means. Although the Company does not believe that its
business activities will be materially affected by changes in the regulatory
environment, it is uncertain what legislative proposals will be adopted or what
actions federal, state or private payors for healthcare goods and services may
take in response to any healthcare reform proposals or legislation. The Company
cannot predict the effects healthcare reform may have on its business, and no
assurance can be given that any such reforms will not have a material effect on
USN.

      In addition, the provision of medical services in the United States is
dependent on the availability of reimbursement to consumers from third party
payors, such as government and private insurance companies. Although patients
are ultimately responsible for services rendered, the Company expects that the
majority of its revenues will be derived from reimbursements by third party
payors. Medicare has authorized reimbursement for Gamma Knife treatment. Over
the last several years, such third party payors are increasingly challenging the
cost effectiveness of medical products and services and taking other
cost-containment measures. Therefore, although treatment costs using the Gamma
Knife compare favorably to traditional invasive brain surgery, it is unclear how
this trend among third party payors and future regulatory reforms affecting
governmental reimbursement will affect procedures in the higher end of the cost
scale.

      In the future, the Company may establish additional Gamma Knife centers.
Completion of future centers would require approvals and arrangements with
hospitals, health care organizations, or other third parties, including certain
regulatory authorities. The Food and Drug Administration has issued the
requisite pre-market approval for the Gamma Knife to be utilized by USN. In
addition, many states require hospitals to obtain a Certificate of Need (CON)
before they can acquire a significant piece of medical equipment. Should the
Company enter into future ventures such "need" will be demonstrable, but it can
have no assurance that Certificates of Need will be granted.

      In addition, the Nuclear Regulatory Commission (NRC) must issue a permit
to


                                       6
<PAGE>

USN to permit loading the COBALT at each Gamma Knife site. While the Company
believes that it can obtain a NRC permit for each Gamma Knife machine, there is
no assurance that it will.

Liability Insurance

      Although USN does not directly provide medical services, it has obtained
professional medical liability insurance, and has general liability insurance as
well. USN's professional medical liability and general liability policies have
limits of $2 million each and USN has also purchased an excess coverage policy
providing an additional $8 million of insurance coverage The Company believes
that its insurance is adequate for providing treatment facilities and
non-medical services, although there can be no assurance that the coverage
limits of such insurance will be adequate or that coverage will not be reduced
or become unavailable in the future.

Competition

      The health care industry, in general, is highly competitive and the
Company expects to have substantial competition from other independent
organizations, as well as from hospitals in establishing future Gamma Knife
centers. There are other companies that provide the Gamma Knife on a "cost per
treatment basis". In addition, larger hospitals may be expected to install Gamma
Knife technology as part of their regular inpatient services. Some of these
competitors have greater financial and other resources than the Company.
Principal competitive factors include quality and timeliness of test results,
ability to develop and maintain relationships with referring physicians,
facility location, convenience of scheduling and availability of patient
appointment times. The


                                       7
<PAGE>

Company believes that cost containment measures will encourage hospitals to seek
companies that are providing the technology, instead of incurring the capital
cost of establishing their own Gamma Knife centers.

Gamma Knife Supply and Servicing

      Currently the only company that manufactures, sells, and services the
Gamma Knife is Elekta Instruments, Inc., a subsidiary of AB Elekta of Stockholm,
Sweden. In 1993, USN entered into purchase agreements with Elekta for the
purchase of the Gamma Knives at its RMC and NYU centers. The purchase price for
each Gamma Knife was approximately $3,000,000. Elekta was responsible for the
installation and testing of the equipment and the training of the hospital staff
in the operation of the equipment. As part of the purchase of the Gamma Knife
devices from Elekta, USN entered into purchase and maintenance agreements
pursuant to which Elekta provides USN with ongoing maintenance, repairs and
software upgrades for the RMC and NYU Gamma knives at an aggregate cost of
$120,000 per year. Any interruption in the supply or services from Elekta would
adversely affect USN's ability to maintain its Gamma Knife treatment centers.

Gamma Knife Financing

      The Gamma Knife is an expensive piece of equipment presently costing
approximately $3,400,000. Therefore, the Company's development of new Gamma
Knife centers is dependent on its ability to secure favorable financing. On
February 8, 2000, the Company entered into a cobalt reloading agreement with
Elekta for the RMC Gamma Knife in the amount of $650,000, which is being
financed by DVI pursuant to an agreement dated March 16, 2000 at the rate of
prime plus one percent, payable in forty monthly installments of $19,383. In the
fourth quarter of 2000 the Company completed


                                       8
<PAGE>

the reload on the RMC unit. The cost to transport it and install into the
machine were approximately $200,000 and were financed by DVI at the same terms
as above, requiring forty monthly installments of $5,782.

New Technology/Possible Obsolescence

      Gamma Knife technology may be subject to technological change.
Consequently, the Company will have to rely on the Gamma Knife's manufacturer,
Elekta, to introduce improvements or upgrades in order to keep pace with
technological change. Any such improvements or upgrades which the Company may be
required to introduce will require additional financing. In addition, newly
developed techniques and devices for performing brain surgery may render the
Gamma Knife less competitive or obsolete.

Employees

      U.S. Neurosurgical, Inc. has five full-time employees and one part-time
employee. Of these employees, three are engaged in sales and marketing, one
physicist, and two in administration and office support.

ITEM 2. PROPERTIES

      The Company's base facility, from which it conducts substantially all of
its administrative operations, is located in Rockville, Maryland and occupies
approximately 1,300 square feet. The rent is approximately $35,000 per year. USN
occupies approximately 1,600 square feet in its RMC facility. This facility is
located on the campus of RMC in Kansas City, Missouri. USN also occupies about
2,000 square feet at the NYU Medical Center in New York, New York. Pursuant to
the facility agreements with RMC and NYU, USN is not required to pay separate
rent for the premises occupied by its Gamma Knife centers. USN's agreements with
RMC expire in September 2015 and


                                       9
<PAGE>

there are no renewal options. USN's agreement with NYU expires in November 2003
and NYU has options to renew the agreement for successive three year periods
thereafter.

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

      The following discussion should be read in conjunction with the Financial
Statements and Notes set forth elsewhere in this report.

Results of Operations

2000 Compared to 1999

      Patient revenue decreased 17% to $2,575,000 in 2000 from $3,089,000 in
1999. The decrease was a result of two factors. The center in Kansas City closed
for more than one month at the end of the third quarter 2000 in order to reload
the cobalt source. In addition, effective August 1, 2000, the Department of
Health and Human Services implemented the Ambulatory Product Classifications
("APC") Medicare outpatient payment system. Gamma Knife patients, with Medicare
as their primary insurer and treated on either an in-patient or out-patient
basis, comprise an estimated 20% to 30% of the total patients treated. The
reimbursement for Medicare patients receiving Gamma Knife services on an
outpatient basis has decreased by as much as 80%. Patient expenses decreased 2%
to $1,097,000 in 2000 from $1,115,000 in 1999. Selling, general and
administrative expense (S,G & A) decreased 6% to $1,366,000 in 2000 from
$1,455,000 in 1999, primarily due to reduced professional fees.

      As a result of the above income from operations declined to $112,000 from
$529,000 in 1999. Interest expense declined to $318,000 in 2000 from $409,000 in
1999. This was due to the paydown of principal on the Gamma Knife lease. The
Company also had extraordinary income of $109,000, net of taxes, in 2000 from a
collection of a receivable which originated with GHS. The net loss was $17,000
in 2000 compared to net income of $66,000 in 1999.

1999 Compared to 1998

      Patient revenue increased 32% to $3,089,000 in 1999 from $2,332,000 in
1998. The increase was due to an increase in the number of treatments at our New
York and Kansas City centers. The Company has increased its marketing and
training of physicians at the NYU facility and expects to continue to increase
its presence at both of the centers. Patient expenses decreased 9% to $1,115,000
in 1999 from $1,221,000 in 1998. S,G & A


                                       13
<PAGE>

increased 26% to $1,445,000 in 1999 from $1,148,000 in 1998. The increase was
due to professional fees related to the spin-off of USN by GHS, Inc of $250,000.
In 1998 the Company incurred expenses of $934,000 related to a litigation
settlement (See Item 13). There was no such expense in 1999.

      For the year ended December 31, 1999 income from operations was $529,000
compared to a loss of $971,000 in 1998. Interest expense decreased to $409,000
in 1999 compared to $555,000 in 1998. The decrease was due to paydown of
principal on the Gamma Knife capital leases. Net income in 1999 was $66,000 as
compared to a loss of $1,011,000 in 1998.

Liquidity and Capital Resources

      At December 31, 2000 the Company had a working capital deficit of $787,000
as compared to $742,000 at December 31, 1999. Cash and cash equivalents at
December 31, 2000 were $286,000 as compared to $464,000 at December 31, 1999.
The decrease is primarily due to a lengthy collection process from one of its
clients. Net cash provided by operating activities was $910,000 as compared with
$1,334,000 for the same period, a year earlier. Depreciation and amortization
was $1,174,000 as compared to $1,136,000 in 1999.

      Net cash used in investing activities for the year ended 2000 was $850,000
as compared to $42,000 in the year ago period. The Company reloaded the cobalt
on its Kansas City unit during the current year.

      Net cash used in financing activities for the year ended December 31, 2000
was $238,000 as compared to $849,000 in 1998. The Company paid $1,079,000
towards its capital leases in 2000 as compared to $1,423,000 in 1999. During
2000 the lease for the Kansas City Gamma Knife was paid in full. The Company
financed $844,000 for the reload of the cobalt and improvements. There were cash
and services received by GHS of $674,000 in 1999.

      The leases for the NYU equipment require annual payments of $792,000. The
Kansas City Cobalt reload has annual payments of $300,000. In addition, as part
of the


                                       14
<PAGE>

settlement of litigation involving GHS and USN in May 1999, USN issued
promissory notes in the aggregate amount of $450,000, bearing interest at the
rate of 6% per annum, and payable over a four-year period as follows: $100,000
on the first, third and fourth anniversaries of closing of the settlement and
$150,000 on the second anniversary of such closing. Management believes that the
capital resources derived through internally generated funds from operations and
current cash balances will be sufficient to satisfy the Company's operating and
capital needs for the forseeable future.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      In 1993, pursuant to an agreement (the "USN Agreement") between the
Company and A. Hyman Kirshenbaum, M.D. ("Kirshenbaum") and Jerry Brown, Ph.D
("Brown") , the Company, among other things, granted an aggregate 20% interest
in USN to Brown and Kirshenbaum. In addition, following the execution of the USN
agreement, Kirshenbaum was appointed as an officer of USN and Brown was
appointed to the Company's Board of Directors and executed an employment
agreement with USN. Under the terms of the USN Agreement, the Company possessed
the right to repurchase for cash or Common Stock such 20% interest during each
of the third through sixth full fiscal years of the USN Agreement at a value to
be calculated by the Company in accordance with the terms of the USN Agreement.
The Company exercised its right to repurchase the 20% interest in USN in
November 1996 at a value of $38,781.40, which value was disputed by Brown and
Kirshenbaum.

      In June 1997, the Company instituted an action (the "Declaratory Action")
in the United States District Court of Maryland, Southern Division against
Kirshenbaum and Brown seeking a declaration from the Court that its repurchase
of Brown's and Kirshenbaum's 20% interest in USN for $38,781.40 was fair and
equitable. In response to the Declaratory Action, Brown and Kirshenbaum filed a
counterclaim and third party claim against GHS, USN, Alan Gold and Allen & Co.
Incorporated, a significant stockholder of GHS, citing various claims including
causes of action for breach of contract and fraud. USN filed a counterclaim
against Brown and Kirshenbaum alleging various torts claims arising out of the
business relationship.

      In addition to the above described federal court action, Brown filed a
state court action in the District Court in and for Montgomery County, Maryland
against USN and other parties seeking breach of contract damages for lost
salary, unreimbursed expenses and for consequential damages and costs arising
out of what he claims to be an improper termination from USN.

      On May 25, 1999, the parties to the above-described actions settled all of
above described legal proceedings pursuant to an Agreement and Plan of
Settlement dated March 22, 1999 between Brown, Kirshenbaum, GHS, USN, Alan Gold,
and Allen & Company. As part of the closing of such settlement, GHS delivered
$200,000 in cash and 68,688 additional shares of GHS common stock to Brown and
Kirshenbaum. In addition,


                                       21
<PAGE>

USN delivered to Brown and Kirshenbaum promissory notes (the "Settlement Notes")
in the aggreagate amount of $450,000, bearing interest at the rate of 6 % per
annum, and payable over a four-year period as follows: $100,000 on the first,
third and fourth anniversaries of such closing and $150,000 on the second
anniversary of such closing. USN will be solely responsible for the payment of
the Settlement Notes.. The Settlement Notes are secured by a second-priority
security interest in USN's receivables from its Kansas City and New York Gamma
Knife centers. On June 9, 1999, the Declaratory Action was dismissed with
prejudice by the parties, and said dismissal was approved by the District Court
judge.

      As consideration for financial advisory services rendered by Allen &
Company Incorporated ("Allen") to GHS in connection with GHS's acquisition of
ChangeYourLife.com, LLC and Concept Development Inc. on May 27, 1999, GHS agreed
to pay Allen a financial advisory fee of $400,000, payable in installments of
$100,000 on each of August 1, 1999, August 1, 2000, September 1, 2000 and
October 1, 2000. As a result of the Assignment and Assumption Agreement entered
into between GHS and USN in connection with USN's Spinoff from GHS, USN will be
solely responsible for the payment of such fees because such fees relate to
events occurring prior to May 27 , 1999. Allen is a significant shareholder of
the Company.

      In May 1999, GHS retained Scott & Stringfellow, an investment banking
firm, to prepare an appraisal of USN in connection with the Spin-off. Mr.

INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
U.S. NeuroSurgical, Inc.
Rockville, Maryland

We have audited the accompanying consolidated balance sheets of U.S.
NeuroSurgical, Inc. and subsidiary as of December 31, 2000 and 1999, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the years in the three-year period ended December 31, 2000.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 enumerated above present
fairly, in all material respects, the consolidated financial position of U.S.
NeuroSurgical, Inc. and subsidiary as of December 31, 2000 and 1999, and the
consolidated results of their operations and cash flows for each of the years in
the three-year period ended December 31, 2000 in conformity with generally
accepted accounting principles.

U.S. NEUROSURGICAL, INC. AND SUBSIDIARY

Notes to Consolidated Financial Statements

NOTE A - THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES

[1]   Basis of preparation:

      U.S. NeuroSurgical, Inc. ("USN") owns and operates stereotactic
      radiosurgery centers, utilizing the Gamma Knife technology. U.S.
      NeuroSurgical Physics, Inc. ("USNP") administers the billing and
      collection of the fees charged by the physicist who operates the Kansas
      City gamma knife. USN and USNP are collectively referred to herein as the
      Company. The Company was a wholly owned subsidiary of GHS, Inc. ("GHS"), a
      publicly owned company. Effective May 27, 1999, GHS transferred its
      investment in USNP to USN. On May 20, 1999 the Board of Directors of USN
      authorized a stock split of USN's common stock which would result in the
      number of outstanding shares of USN common stock equaling the number of
      shares of GHS common stock outstanding on the date of the spin-off. The
      Board of Directors of GHS resolved to distribute such common shares to its
      own stockholders on a one-to-one basis in a spin-off transaction.
      Immediately following the spin-off, USN became a publicly held company.

      The consolidated financial statements include the accounts of USN and
      USNP. All intercompany transactions and balances have been eliminated.

      Management of the Company believes that its cash from operations plus cash
      on hand as of December 31, 2000 will be sufficient to fund its cash
      requirements through at least January 1, 2002, although there can be no
      assurances that this will be the case.

[2]   Revenue recognition:

      Patient revenue is recognized when the Gamma Knife procedure is rendered.

[3]   Long-lived assets:

      The Company reviews its long-lived assets for impairment whenever events
      or changes in circumstances indicate that the carrying amount of an asset
      may not be recoverable.

[4]   Depreciation and amortization:

      The Gamma Knives are being depreciated on the straight-line method over an
      estimated useful life of seven years. Leasehold improvements are being
      amortized on the straight-line method over 7 to 20 years, the life of the
      leases.

[5]   Net earnings (loss) per share:

      Net earnings (loss) per share gives retroactive effect to the stock split
      and spin-off described in Note A[1].

[6]   Statements of cash flows:

      For purposes of the statements of cash flows, the Company considers all
      highly liquid debt instruments purchased with a maturity of three months
      or less to be cash equivalents.

[7]   Estimates and assumptions:

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      contingent assets and liabilities at the date of the financial statements
      and the reported amounts of revenues and expenses during the reporting
      period. Actual results could differ from those estimates.


                                                                             F-7

Notes to Consolidated Financial Statements

NOTE A - THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

[8]   Fair values of financial instruments:

      The estimated fair value of financial instruments has been determined
      based on available market information and appropriate valuation
      methodologies. The carrying amounts of cash, certificates of deposit,
      accounts receivable, other current assets and accounts payable approximate
      fair value at December 31, 2000 and 1999 because of the short maturity of
      these financial instruments. The carrying values of the obligations under
      capital leases and loans payable approximate fair value because the
      interest rates on these instruments approximate the market rates at
      December 31, 2000 and 1999.

NOTE B - AGREEMENTS WITH RESEARCH MEDICAL CENTER ("RMC")

[1]   Gamma Knife neuroradiosurgery equipment agreement:

      USN entered into a neuroradiosurgery equipment agreement (the "equipment
      agreement") with RMC, a stockholder of the Company for a period of 21
      years, which commenced, with the completion of the neuroradiosurgery
      facility (the "facility") in September 1994. The equipment agreement,
      among other matters, requires USN to provide (i) the use of the Gamma
      Knife equipment (the "equipment") to RMC, (ii) the necessary technical
      personnel for the proper operation of the equipment, (iii) sufficient
      supplies for the equipment, (iv) the operation, maintenance and repair of
      the equipment, (v) all basic hardware and software updates to the
      equipment and, (vi) an uptime guarantee. In return, RMC pays USN 80% of
      RMC's fees for the use of the equipment and the facility. The agreement
      also provides for USN to establish for the benefit of RMC an escrow
      account funded with an amount equal to one month's average of the
      compensation payable to USN. USN is the owner of and entitled to the
      income from the escrow account so long as no event of default has
      occurred. As of December 31, 2000 and 1999, the escrow account had a
      balance of $101,000 and $96,000, respectively. The equipment agreement
      terminates automatically upon termination of the ground lease agreement
      (see Note B[2]). The Company had patient revenue from RMC in the amounts
      of $1,341,000, $2,081,000 and $1,425,000 for the years ended December 31,
      2000, 1999 and 1998, respectively.

[2]   Ground lease agreement:

      USN constructed a facility in Kansas City, Missouri on property which the
      Company leases from RMC. The lease term is for a period of 21 years
      commencing September 1994. The lease provides for rent at $3,600 per
      annum. The terms of the lease include escalation clauses for increases in
      certain operating expenses and for payment of real estate taxes and
      utilities. Title to all improvements upon the land vests in RMC.

NOTE C - AGREEMENT WITH NEW YORK UNIVERSITY ON BEHALF OF NEW YORK UNIVERSITY
         MEDICAL CENTER ("NYU")

During November 1996, USN entered into a neuroradiosurgery equipment agreement
("NYU agreement") with NYU for a period of seven years ("the term"), with an
option for NYU to extend the term for successive three-year periods or to
purchase the Gamma Knife equipment at an appraised market value price. USN may
negotiate the purchase price and upon failure of the parties to agree may
request that the facility be closed. All costs associated with closing and
restoring the facility to its original condition will be the liability of USN.
The equipment agreement, among other matters, requires USN to provide (i) the
use of the Gamma Knife equipment to NYU, (ii) training necessary for the proper
operation of the Gamma Knife equipment, (iii) sufficient supplies for the
equipment, (iv) the repair and maintenance of the equipment, (v) all basic
hardware and software upgrades to the equipment and, (vi) an uptime guarantee.
In return, NYU is to pay USN a scheduled fee based on the number of patient
procedures performed. The Company had patient revenue from NYU in the amounts of
$1,234,000, $1,008,000 and $907,000 for the years ended December 31, 2000, 1999
and 1998, respectively.


                                                                             F-8

NOTE D - OBLIGATION UNDER CAPITAL LEASE AND LOANS PAYABLE

USN acquired its first Gamma Knife ("Knife 1") from Elekta Instruments
("Elekta") for $2,900,000 under a capital lease. The Company refinanced the
lease with DVI Financial Services, Inc. ("DVI") under a 39-month capital lease
with an implicit interest rate of approximately 10.4%.

On December 6, 1994, USN entered into an additional agreement with Elekta to
acquire a second Gamma Knife ("Knife 2') for $2,900,000 which was also financed
by DVI pursuant to a capital lease obligation. The lease terms provide for
interest at the higher of 12.0% or that rate adjusted for any increase in the
thirty month Treasury Note rate.

In addition, USN had entered into two (2) three-year loans with DVI in the
amounts of $325,000 and $163,000 to finance the leasehold improvements required
to install the Gamma Knife at NYU. The loans were repaid in full during 1999 and
2000, respectively. The leases and loans payable were collateralized by all the
assets of the Company.

During 2000, USN entered into two(2) three-year loans with DVI in the amounts of
$625,000 and $194,000 to finance the removal and reinstallation of the supply of
cobalt at RMC. The loans bear interest at 10.7% per annum and are collateralized
by the Gamma Knife at RMC.

The obligations under the capital lease and loans payable are as follows:

Notes to Consolidated Financial Statements

NOTE F - TAXES (CONTINUED)

In 2000 and 1999, no valuation allowance was provided for the deferred tax asset
because management believes that it is more likely than not that the benefit
will be realized through future taxable income.

NOTE G - LITIGATION

In settlement of a litigation in May 1999, the Company paid $200,000 cash and
issued promissory notes (the "Settlement Notes") in the aggregate amount of
$450,000, bearing interest at the rate of 6% per annum, and payable over a
four-year period as follows: $100,000 on the first, third and fourth
anniversaries of such closing and $150,000 on the second anniversary of such
closing. The Settlement Notes are secured by a second-priority security interest
in the Company's receivables from its Kansas City and New York Gamma Knife
centers. During 1998, $934,000 was charged to expense for this settlement
including the value of 68,688 shares of common stock issued by GHS.
