Disclosure Regarding Forward Looking Statements

Statements contained in this Annual Report on Form 10-K that are not
historical facts are forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Investors are cautioned that
forward-looking statements are inherently uncertain. Actual performance and
results may differ materially from that projected or suggested herein due to
certain risks and uncertainties including, without limitation, the outcome of
the Company's payment, timing and ultimate collectability of accounts receivable
for Gamma Knife procedures from different payor groups such as Medicare and
private payors; competition; technological obsolescence; government regulation;
and malpractice liability. Additional information concerning certain risks and
uncertainties that could cause actual results to differ materially from that

filings with the Securities and Exchange Commission (SEC) and the Company's
public announcements, copies of which are available from the SEC or from the
Company upon request.

U. S. NeuroSurgical, Inc.

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 Gamma Knife centers, one on the premises of Research Medical
Center (RMC) in Kansas


2


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, 2001, there
were approximately 55 Gamma Knife treatment centers in the United States.

Through September 9, 1999, USN was a wholly owned subsidiary of GHS, Inc
("GHS"). Effective on September 17, 1999 GHS distributed its shares of USN to
the stockholders of GHS ( the "Spinoff").

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


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., 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, 2001 and the fiscal years 2000 and 1999 USN derived revenues from the RMC
center of approximately $1,397,000, $1,341,000 and $2,081,000


4


respectively, as a result of 114, 116 and 153 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, 2001, 2000, and 1999,
USN derived revenues from the NYU center of approximately $1,176,000, $1,234,000
and $1,008,000, respectively, as a result of 148, 121 and 98 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


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 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


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


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


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. In May of 2001 the
Company borrowed $200,000 to fund its short term obligations. The term of the
loan is 40 months and carries an interest rate of 9.5% and has a monthly payment
of $5,851.

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 is a
physicist, and two are 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 $36,000 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


9


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 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

2001 Compared to 2000

Patient revenue was $2,573,000 in 2001 compared to $2,575,000 in 2000. The
Company continues to experience the effects of the Department of Health and
Human Services implementation of the Ambulatory Product Classifications ("APC")
Medicare outpatient payment system in August 2000. 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 8% to $1,013,000 in 2001 from $1,097,000 in 2000. The reason for the
decrease is that one of the knives has been fully depreciated. Selling, general
and administrative expense (S,G & A) increased 3% to $1,402,000 in 2001 from
$1,366,000 in 2000.

As a result of the above income from operations increased to $158,000 in
2001 from $112,000 in 2000. Interest expense declined to $277,000 in 2001 from
$318,000 in 2000. This was due to the paydown of principal on the Gamma Knife
lease. The Company also had extraordinary income of $67,000, net of taxes, in
2001 from a collection of a receivable which originated with GHS. The benefit of
income taxes in 2001 was $163,000 compared to $68,000 in 2000. This was
primarily due to the finalization of the tax effects of the spinoff which took
place in 1999. Net income was $120,000 in 2001 compared to a net loss of $17,000
in 2000.

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,


13


the Medicare APC payment system was implemented. 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.

Liquidity and Capital Resources

At December 31, 2001 the Company had a working capital deficit of $677,000
as compared to a working capital deficit of $787,000 at December 31, 2000. Cash
and cash equivalents at December 31, 2001 were $311,000 as compared to $286,000
at December 31, 2000. Net cash provided by operating activities was $763,000 as
compared with $910,000 for the same period a year earlier. In the previous year
the Company made a provision for doubtful accounts of $150,000. During 2001 the
Company wrote off those receivables. Depreciation and amortization was
$1,129,000 as compared to $1,174,000 in 2000. The Company issued $40,000 worth
of stock as compensation to officers and directors in 2001.

Net cash used in investing activities for the year ended 2001 was $4,000
as compared to $850,000 in the year ago period. The Company reloaded the cobalt
on its Kansas City unit during 2000.

Net cash used in financing activities for the year ended December 31, 2001
was $734,000 as compared to $238,000 in 2000. The Company paid $922,000 towards
its capital leases in 2001 as compared to $1,079,000 in 2000. 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 during 2000. The Company
also bought back 250,500 shares of common stock during 2001 at a cost of
$12,000.


14


The leases for the NYU equipment require annual payments of $792,000. The
Kansas City Cobalt reload has annual payments of $360,000. In addition, as part
of the 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


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.
Charles H. Merriman III, a director of GHS and USN , is a Managing Director of
Scott & Stringfellow.

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. & subsidiary as of December 31, 2001 and 2000, 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, 2001.
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 auditing standards generally accepted
in the United States of America. 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. & subsidiary as of December 31, 2001 and 2000, and the
consolidated results of their operations and their cash flows for each of the
years in the three-year period ended December 31, 2001 in conformity with
accounting principles generally accepted in the United States of America.

DRAFT- SUBJECT TO REVIEW
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 resulted 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 and the Company did
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. 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, 2001 will be sufficient to fund its cash
requirements through at least January 1, 2003, 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 accounting
principles generally accepted in the United States of America 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.

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, accounts receivable, other
current assets and accounts payable approximate fair value at December 31,
2001 and 2000 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, 2001 and
2000.

[9] Recently issued accounting pronouncement:

In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143, "Accounting for Asset Retirement
Obligations" ("SFAS 143"). SFAS 143 is effective for fiscal years
beginning after June 15, 2002 and requires companies with legal
obligations associated with the retirement of a tangible long-lived asset
to recognize the fair value of the liability in the period in which it is
incurred if a reasonable estimate of the fair value can be made. Such
liability is to be capitalized as a cost of the related asset.
Additionally, if an asset is acquired with a legal obligation for its
retirement, the fair value of the liability shall be recorded upon
acquisition.

The Company will be required to adopt SFAS 143 in the year ending December
31, 2003 and has not yet determined the effect of such adoption. As
disclosed in Note C, the Company has an obligation to restore its gamma
knife facility at New York University Medical Center ("NYU") to its
original condition upon the closing of the facility. The timing and the
ultimate cost of such restoration have not been determined.

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, subject to adjustments, 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, 2001 and 2000, the escrow account
had a balance of $105,000 and $101,000, 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 $1,397,000, $1,341,000 and $2,081,000 for the years ended
December 31, 2001, 2000 and 1999, 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 responsibility 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 pays USN a scheduled fee based on the number of patient
procedures performed. The Company had patient revenue from NYU in the amounts of
$1,176,000, $1,234,000 and $1,008,000 for the years ended December 31, 2001,
2000 and 1999, respectively.

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.

On May 22, 2001, USN entered into a forty-month loan agreement with DVI in the
amount of $200,000. The loan bears interest at 9.479% per annum and is
