                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY ACCOUNTING POLICIES

          The Company - National Surgery Centers, Inc. and subsidiaries
(collectively the "Company") acquires, develops and manages ambulatory surgery
centers.  Many of the Company's surgery centers are operated in partnership with
physicians and other health care providers.

          The accompanying unaudited interim financial statements of the Company
have been prepared in accordance with generally accepted accounting principles
for interim financial information.  In the opinion of management, all
adjustments (consisting only of normal recurring adjustments) have been made
which are necessary for a fair presentation of the financial position, results
of operations, and cash flows for the interim periods presented.  The interim
statements presented herein do not include all disclosures normally provided in
annual financial statements.

          Principles of Consolidation - The consolidated financial statements
include all accounts of the Company and its wholly-owned subsidiaries and
controlled partnerships.  All significant intercompany balances and transactions
have been eliminated in consolidation.

          Common Share Data - Primary income per common and common equivalent
share and income per common and common equivalent share assuming full dilution
are computed using the weighted average number of shares outstanding adjusted
for the incremental shares attributable to outstanding options and warrants to
purchase common stock.  Certain convertible debt is dilutive and, therefore, is
included in the fully diluted weighted average number of shares outstanding for
the three and nine month periods ending September 30, 1996.

          Stock Exchange - Effective May 31, 1996, the Company effected a 3-for-
2 stock split in the form of a 50% stock dividend.  Accordingly, all references
in these unaudited interim financial statements to shares, average number of
shares outstanding and per share amounts have been restated to reflect this
stock split.

NOTE 2 - ACQUISITIONS

          Purchases - During January, February, April and May, 1996, the Company
acquired three multi-specialty surgery centers and two companies which operated
specialty endoscopy centers.  The aggregate purchase price was $13.6 million in
cash and of this purchase price, $ 11.9 million was recorded as goodwill.  Also,
during each of August and October, 1995, the Company acquired a multi-specialty
surgery center.  The following unaudited results of operations give effect to
the operations of the entities acquired in the first and second quarters of 1996
and during 1995 as if these respective transactions had occurred as of the first
day of 1995.  The pro forma results of operations do not purport to represent
what the Company's results would have been had such transactions in fact
occurred at the beginning of the periods presented or to project the Company's
results of operations in any future period.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

OVERVIEW

          The Company's growth has resulted primarily from the acquisition and
development of ambulatory surgery centers.  Since 1991, the Company has
completed the acquisition of 28 ambulatory surgery centers, including two
centers in which the Company has minority ownership positions; developed two
centers in which it has majority equity ownership; and developed centers for
other health care providers, including one hospital.

          In January, April and May, 1996, the Company acquired three multi-
specialty surgery centers; in February 1996, the Company acquired a convertible
subordinated note which was converted in March 1996 into 90% of the common stock
of Endoscopy Center Affiliates, Inc., which operates and develops specialty
endoscopy centers; and in May 1996, the Company acquired a majority interest in
three specialty endoscopy centers.  Additionally, in September 1996, the Company
acquired a ten percent interest in a multi-specialty surgery center and divested
its interest in a multi-specialty center in Dallas, Texas. In each of August and
October 1995, the Company acquired a multi-specialty surgery center, each of
which is operating as a limited partnership.  All of these acquisitions have
been accounted for under the purchase method of accounting.

          During July and September 1996, the Company redeemed $1.4 million of
its convertible subordinated notes into 97,293 shares of common stock.

          Because of the financial impact of the Company's recent acquisitions
and developments, it is difficult to make meaningful comparisons between the
Company's financial statements to the comparable period in 1995.  In addition,
due to the limited number of operated surgery centers, each additional center
acquired or developed can affect the overall operating margin of the Company.
Upon the acquisition of a surgery center, the Company has typically implemented
certain steps to improve operating margins.  The impact of such actions and of
other activities to improve operating margins may not occur immediately.
Consequently, the financial performance of an acquired surgery center may
adversely affect overall operating margins in the near-term.  As the Company
makes additional surgery center acquisitions, the Company expects that this
effect will be mitigated by the expanded financial base of the existing surgery
centers.

          The Company's principal source of revenue is a facility fee charged
for surgical procedures performed in its surgery centers.  This fee varies
depending on the procedure performed, but usually includes all charges for
operating room usage, special equipment usage, supplies, recovery room usage,
nursing staff and medications.  Facility fees do not include the charges of the
patients' surgeons, anesthesiologists or attending physicians, which are billed
directly by such physicians. For those surgery centers providing extended
recovery care, an additional fee is typically charged for an overnight stay.
This fee generally includes a flat fee for post-operative care and may include
itemized amounts for medications and other supplies.

THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995

          Net Revenue. Net revenue is net of provisions for contractual
adjustments and doubtful accounts. Net revenue increased 50.1% to $20.1 million
in 1996 from $13.4 million in 1995. Overall net revenue per case declined 10.6%
to $880 in 1996 from $984 in 1995, primarily due to the inclusion of eleven
specialty endoscopy centers acquired during 1996. Separately, net revenue per
case was $1,018 for the multi-specialty centers and $482 for the specialty
endoscopy centers. Same center net revenue increased $1.7 million or 13.4 % due
to a 11.7% increase in cases combined with a 1.5% increase in net revenue per
case to $997 from $982.

          Operating Expenses. Operating expenses include salaries and benefits,
drugs and medical supplies, utilities, marketing, maintenance costs and rent
expense of the centers. Operating expenses increased 39.8% to $13.3 million in
1996 from $9.5 million in 1995. Of this increase, $3.2 million resulted from
centers acquired in 1996 and 1995. As a percentage of net revenue, operating
expenses decreased to 66.2% in 1996 from 71.1% in 1995.

          General and Administrative Expenses. General and administrative
expenses include only corporate-level expenses and do not include any center-
level administrative expenses. General and administrative expenses increased
69.1% to $942,000 in 1996 from $557,000 in 1995. As a percentage of net revenue,
general and administrative expenses increased to 4.7% in 1996 from 4.2% in 1995.

          Depreciation and Amortization Expense. Depreciation and amortization
expenses increased 77.3% to $1.6 million in 1996 from $916,000 in 1995. Of this
increase, $589,000 resulted from centers acquired in 1996 and 1995. As a
percentage of net revenue, depreciation and amortization expense increased to
8.1% in 1996 from 6.8% in 1995.

          Interest Expense. Interest expense decreased 34.5% to $714,000 in 1996
from $1.1 million in 1995. The decrease in interest expense was primarily the
result of the repayment of the $20.0 million subordinated debt in November 1995
with proceeds from the Company's public offering offset by additional interest
expense related to debt assumed from acquisitions in 1996 and 1995. As a
percentage of net revenue, interest expense decreased to 3.5% in 1996 from 8.1%
in 1995.

          Minority Interests. Minority interests include the limited partners'
ownership share in the earnings (losses) of the operating center partnerships.
Minority interests increased 144.4% to $880,000 in 1996 from $360,000 in 1995.
Of this increase, $356,000 was attributable to centers acquired in 1996 and 1995
with the remaining increase resulting from improved center operating
performance. As a percentage of net revenue, minority interests increased to
4.4% in 1996 from 2.7% in 1995.

     Provision for Income Taxes.  Provision for income taxes increased to $1.1
million in 1996 from $370,000 in 1995. The effective tax rate decreased to 39.4%
in 1996 from 40.9% in 1995 due primarily to the effects of tax-exempt interest
earned during 1996 from short-term investments.

     Net Income.  Net income increased to $1.7 million in 1996 from $535,000 in
1995. As a percentage of net revenue, net income increased to 8.5% in 1996 from

$38.5 million in 1995. Overall net revenue per case declined 8.2% to $912 in
1996 from $993 in 1995, primarily due to the inclusion of the eleven specialty
endoscopy centers acquired in 1996. Seperately, net revenue per case was $1,015
for the multi-specialty centers and $476 for the specialty endoscopy centers.
Same center net revenue increased $5.8 million or 16.0% due to a 13.7% increase
in cases combined with a 2.0% increase in net revenue per case to $1,009 from
$989.

from $3.3 million in 1995. The decrease in interest expense was primarily the
result of the repayment of the $20.0 million subordinated debt in November 1995

expense related to debt assumed from acquisitions in 1996 and 1995. As a
percentage of net revenue, interest expense decreased to 3.6% in 1996 from 8.6%
in 1995.

million in 1996 from $1.2 million in 1995. The effective tax rate decreased to
39.2% in 1996 from 40.0% in 1995 due primarily to the effects of tax-exempt
interest earned during 1996 from short-term investments.

     Net Income.  Net income increased to $5.0 million in 1996 from $1.8 million
in 1995. A a percentage of net revenues, net income increased to 8.9% in 1996
from 4.7% in 1995.

SEASONALITY

     The Company's business experiences some degree of seasonality because
patients have discretion in scheduling elective surgery. The first quarter tends
to be lower due to beginning of the year deductibles while the third quarter
reflects the effects of vacations taken both by patients and physicians.
Although the Company's growth and development of centers may obscure the effects
of seasonality in the Company's financial results, the Company's first and third
quarters generally reflect lower net revenue and operating income margins on a
same center basis when compared to the Company's second and fourth quarters.

LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1996, the Company had working capital of $7.6 million
including cash and cash equivalents and short-term investments of $9.4 million.
The Company's cash flow from operations increased to $7.3 million for the nine
months ended September 30, 1996 from $5.9 million in 1995. The Company's cash
flow from operations combined with proceeds from sale of short-term investments
of $7.9 million, proceeds from sales of assets of $1.0 million and existing cash
and cash equivalents were used primarily to finance acquisitions of $13.9
million, an investment in a partnership of $1.5 million, capital expenditures of
$3.5 million, and repayment of long-term debt of $3.7 million.

     The Company expects that its principal use of funds in the near future will
be in connection with the acquisition and development of surgery centers,
working capital requirements, debt repayments and purchases of property and
equipment. The Company expects that cash and cash equivalents, short-term
investments, cash generated from operations and available credit borrowings will
be adequate to provide for the Company's cash requirements for at least the next
twelve months, unless the rate of acquisitions significantly increases. No
assurances can be given that cash and borrowings will be sufficient to provide
for the Company's cash requirements beyond the next twelve months.

     The Company's credit agreement provides for revolving and term loans of up
to $20.0 million, to be used by the Company for acquisitions and development of
surgery centers and related businesses. As of September 30, 1996, no amount was
outstanding under the credit agreement. Loans under the credit agreement are
secured by substantially all the assets of the Company (including the capital
stock or partnership units of the Company's subsidiaries) and matures on June
30, 2000. Loans under the credit agreement are denominated at the Company's
option as either Eurodollar Tranches (loans bearing interest at a rate of 1.5%
above the London Interbank Offered Rate) or Base Rate Tranches (loans bearing
interest at 0.5% above the prime rate for U.S. commercial loans) subject to
adjustments in certain circumstances.

SUBSEQUENT EVENTS

     During October and November 1996, the Company completed an offering of
2,415,511 common shares priced at $24.25 per share with net proceeds of
approximately $55.2 million. The Company anticipates to use net proceeds to
repay certain indebtedness totaling $10 million, which bears interest at rates
ranging from 7.5% to 13.4% annually. The remaining proceeds will be used for
general corporate purposes, which may include future acquisitions and the
development of surgery centers.

     During September 1996, the Company issued redemption notices with respect
to $4.3 million principal amount of convertible subordinated notes. In October,
$4.2 million of the notes were converted into 359,272 shares of common stock and
$71,000 of such notes were redeemed.
