                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A - Basis of Preparation

      The accompanying financial statements at September 30, 2003, and for the
three and nine months ended September 30, 2003 and 2002, are unaudited. However,
in the opinion of management, such statements include all adjustments necessary
for a fair statement of the information presented therein. The balance sheet at
December 31, 2002 has been derived from the audited financial statements at that
date appearing in the Company's Annual Report on Form 10-K.

      Pursuant to accounting requirements of the Securities and Exchange
Commission applicable to quarterly reports on Form 10-Q, the accompanying
financial statements and these notes do not include all disclosures required by
accounting principles generally accepted in the United States of America for
complete financial statements. Accordingly, these statements should be read in
conjunction with the Company's most recent annual financial statements.

      Results of operations for interim periods are not necessarily indicative
of those to be achieved for full fiscal years.

Note B - Treasury Stock

      During the nine months ended September 30, 2003, the Company purchased as
part of its buyback program, 204,000 shares of its own common stock at an
aggregate cost of $8,000.

                             ANALYSIS OF OPERATIONS
                             AND FINANCIAL CONDITION

Critical Accounting Policies

Our condensed financial statements have been prepared in accordance with
accounting principles generally accepted in the United States of America. As
such, some accounting policies have a significant impact on amounts reported in
the financial statements. A summary of those significant accounting policies can
be found in our 2002 Annual Report on Form 10-K, filed on March 28, 2003, in the
Notes to the Financial Statements, Note A. In particular, judgment is used in
areas such as determining the allowance for doubtful accounts, and asset
impairments.

The following discussion and analysis provides information, which the Company's
management believes is relevant to an assessment and understanding of the
Company's results of operations and financial condition. This discussion should
be read in conjunction with the consolidated financial statements and notes
thereto appearing elsewhere herein.

Results of Operations

Third Quarter 2003 Compared to Third Quarter 2002 and Nine Months Ended
September 30, 2003 Compared to Nine Months Ended September 30, 2002

      Patient revenue decreased 26% to $490,000 in the quarter ended September
30, 2003 from $660,000 for the quarter ended September 30, 2002. The reason for
the decline was a decrease in revenue from NYU caused by temporary closure of
the facility during the quarter to reload the cobalt source. In addition, NYU
has had a reduced patient flow during the quarter. Patient expenses increased
11% to $261,000 from $235,000 in the same period from a year earlier primarily
due to increased depreciation on our NYU gamma knife related to the cobalt
reload. Selling, general and administrative expense for the quarter ended
September 30 increased 7% to $386,000 from $361,000 a year ago. The increase was
primarily due to higher insurance costs. Interest expense decreased 42% to
$21,000 from $36,000 in the same period a year earlier due to repayment of our
leases on the Gamma Knife properties. As a result of decreased revenue and
increase in expenses for the quarter ended September 30, 2003, net loss was
$110,000 as compared to income of $19,000 for the same period a year earlier.

      The reload of the cobalt source at NYU in August of 2003, was financed by
the Company's leasing company, DVI, Inc. On August 13, 2003 DVI, Inc. filed for
reorganization under Chapter 11 of the U.S. Bankruptcy Code. Shortly thereafter
the Company discovered that DVI, Inc. had failed to make the final 20% of the
payments for the reload due to Elekta Instruments, the supplier. The lease was
assigned by DVI, Inc. to U.S. Bank Corporation for the full amount of the cobalt
of $732,000 even though only $582,000 was funded by DVI, Inc. U. S. Bank Corp
claims that $732,000 is due under the lease. The Company vigorously refutes this
claim. Should U.S. Bank Corporation prevail, the Company believes that it may
have liability to U.S. Bank Corporation for the $732,000 in addition to the
$150,000 representing the remaining unfunded amount, still


                                       7
<PAGE>

due to Elekta. The Company recorded a total liability of $732,000 during the
quarter ended September 30, 2003 consisting of obligations under capital leases
of $582,000 and the remaining amount of $150,000, which is included in accounts
payable.

      For the nine months ended September 30, revenue decreased 8% to $1,874,000
from $2,044,000 in the same period a year earlier due to the same reasons as
explained above. Patient expenses increased 5% to $724,000 in 2003 from $691,000
in the same period in 2002. Selling, general and administrative expenses
increased 8% to $1,106,000 as compared to $1,024,000 in the same period, a year
earlier. The increase was due to increased insurance costs. Interest expense
decreased 50% to $68,000 from $135,000 in the same period a year ago. The
decrease was due to repayment of our leases on the Gamma Knife properties. The
net loss was $16,000 for the nine months ended September 30, 2003 as compared to
income of 118,000 for the nine months ended September 30, 2002, due to the
reasons noted above.

Liquidity and Capital Resources

      At September 30, 2003 the Company had a working capital deficit of
$340,000 as compared to a deficit of $665,000 at December 31, 2002. Cash and
cash equivalents at September 30, 2003 were $109,000 as compared with $88,000 at
December 31, 2002. Net cash provided by operating activities was $898,000 for
the nine months ended September 30, 2003 as compared with $630,000 for the same
period, a year earlier. The increase was primarily due to better collection of
accounts receivable from NYU. Depreciation and amortization was $697,000 for the
nine month period ended September 30, 2003 and was 675,000 in the 2002 period.
There was a decrease in accounts receivable of $59,000 in 2003 compared to an
increase of $240,000 during the nine months ended September 30, 2002.

      Accounts payable and accrued expenses increased $185,000 for the nine
months ended September 30, 2003 as compared to $35,000 for the same period in
2002 primarily due to an increase of $150,000 for the liability with Elekta
regarding the cobalt reload and increase in income tax payable.

      Net cash used in financing activities was $136,000 for the nine months
ended September 30, 2003 as compared to $791,000 for the same period a year ago.
The Company incurred $732,000 for the cobalt reload offset by a funding of
$582,000 by DVI, Inc. In addition, the Company paid $710,000 towards repayment
of its capital lease obligations and notes payable for the nine months ended
September 30, 2003 as compared to $783,000 in the same period in 2002.

      The Company expects cash flow from operations and cash on hand to be
sufficient to finance the business for the next twelve months.

Disclosure Regarding Forward Looking Statements

      The Securities and Exchange Commission encourages companies to disclose
forward-looking information so that investors can better understand a company's
future prospects and make informed investment decisions. This document contains
such "forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995, particularly statements anticipating future
growth in revenues and cash flow. Words such as "anticipates," "estimates,"
"expects," "projects," "intends," "plans," "believes," "will be," "will
continue," "will likely result," and words and terms of similar substance used
in connection with any discussion of future operating or financial performance
identify such forward-looking statements. Those forward-looking statements


                                       8
<PAGE>

are based on management's present expectations about future events. As with any
projection or forecast, they are inherently susceptible to uncertainty and
changes in circumstances, and USN is under no obligation to (and expressly
disclaims any such obligation to) update or alter its forward-looking statements
whether as a result of such changes, new information, future events or
otherwise.

      USN operates in a highly competitive and rapidly changing environment and
business segments that are dependent on our ability to: achieve profitability;
increase revenues; sustain our current level of operation; introduce on a timely
basis new products; maintain satisfactory relations with our customers; attract
and retain key personnel; maintain and expand our strategic alliances; and
protect our know-how. USN's actual results could differ materially from
management's expectations because of changes in such factors. New risk factors
can arise and it is not possible for management to predict all such risk
factors, nor can it assess the impact of all such risk factors on the company's
business or the extent to which any factor, or combination of factors, may cause
actual results to differ materially from those contained in any forward-looking
statements. Given these risks and uncertainties, investors should not place
undue reliance on forward-looking statements as a prediction of actual results.

      Investors should also be aware that while the company might, from time to
time, communicate with securities analysts, it is against the company's policy
to disclose to them any material non-public information or other confidential
commercial information. Accordingly, investors should not assume that the
company agrees with any statement or report issued by any analyst irrespective
of the content of the statement or report. Furthermore, the company has a policy
against issuing or confirming financial forecasts or projections issued by
others. Thus, to the extent that reports issued by securities analysts or others
contain any projections, forecasts or opinions, such reports are not the
responsibility of the company.

In addition, USN's overall financial strategy, including growth in operations,
maintaining financial ratios and strengthening the balance sheet, could be
adversely affected by increased interest rates, failure to meet earnings
expectations, significant acquisitions or other transactions, economic slowdowns
and changes in USN's plans, strategies and intentions

ITEM 4. CONTROLS AND PROCEDURES

      U.S. Neurosurgical management, including the President and the Chief
Financial Officer, conducted an evaluation of the effectiveness of disclosure
controls and procedures pursuant to Exchange Act Rule 13a-14 within 90 days of
the filing of this report. Based on that evaluation, the President and the Chief
Financial Officer concluded that the disclosure controls and procedures are
effective in ensuring that all material information required to be filed in this
quarterly report has been made known to them in a timely fashion. There have
been no significant changes in internal controls, or in factors that could
significantly affect internal controls, subsequent to the date the President and
the Chief Financial Officer completed their evaluation.
