                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and consolidated financial
statements, including the notes thereto, appearing elsewhere in this Prospectus.
All figures have been adjusted to give effect to a recapitalization on December
3, 1997 pursuant to which every three shares of the Company's then outstanding
common stock were converted into one share of Class A Common Stock. Unless
otherwise indicated, the information contained in this Prospectus assumes (i)
the conversion of the Company's Series B Convertible Preferred Stock (the
"Series B Preferred Stock") into approximately 607,500 shares of Class A Common
Stock upon the completion of the Offering and (ii) no exercise of the
Underwriters' over-allotment option. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from the results discussed in the forward-looking
statements. Factors that might cause such a difference include, but are not
limited to, those discussed in "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business," as
well as those described elsewhere in this Prospectus.
 
                                  THE COMPANY
 
   
     The Company develops, acquires and operates practice-based ambulatory
surgery centers, in partnership with physician practice groups, throughout the
United States. As of May 1, 1998, the Company owned a majority interest in 44
surgery centers and a minority interest in one center in 20 states and the
District of Columbia. The Company also had six centers under development, had
executed letters of intent to develop or acquire six additional centers and had
two centers awaiting certificate of need ("CON") approval. The Company believes
that it is a leader in the ownership and operation of practice-based ambulatory
surgery centers.
    
 
     The Company's centers are licensed for outpatient surgery, are generally
equipped and staffed for a single medical specialty and are usually located in
or adjacent to the offices of a physician group practice. The Company has
targeted ownership in centers that perform gastrointestinal endoscopy,
ophthalmology, urology, orthopaedics or otolaryngology procedures. Surgical
procedures associated with these specialties include many types of high volume,
lower-risk procedures that are appropriate for the practice-based setting. The
Company believes its single specialty centers have significantly lower capital
and operating costs than hospital and freestanding ambulatory surgery center
alternatives that are designed to accommodate a broader array of surgical
specialties and procedures. In addition, the practice-based surgery center
provides a more convenient setting for the patient and for the physician
performing the procedure.
 
     In recent years, government programs, private insurance companies, managed
care organizations and self-insured employers have implemented various
cost-containment measures to limit the growth of healthcare expenditures. These
cost-containment measures, together with technological advances, have resulted
in a significant shift in the delivery of healthcare services away from
traditional inpatient hospitals to more cost-effective alternate sites,
including ambulatory surgery centers. According to SMG Marketing Group Inc.'s
Freestanding Outpatient Surgery Center Directory (June 1997), an industry
publication, outpatient surgical procedures represented approximately 69% of all
surgical procedures performed in the United States in 1996. The number of
outpatient surgery cases increased 54% from 3.1 million in 1993 to 4.8 million
in 1996. As of December 31, 1996, there were 2,425 freestanding ambulatory
surgery centers in the United States, of which 171 were owned by hospitals and
607 were owned by corporate entities. The remaining 1,647 centers were
independently owned, primarily by physicians.
 
     The Company's strategy focuses on providing high volume, lower-risk
ambulatory surgery services in single specialty settings, which results in lower
costs, improved operating efficiencies and greater convenience and appeal to
patients, physicians, private and governmental payers and managed care
organizations. The Company intends to continue to grow through the acquisition
of existing centers and the development of new centers. In addition, the
Company's center operations are designed to enhance physician productivity and
maximize the efficient use of the centers. Furthermore, the Company believes
that it can make its centers more attractive to managed care organizations
through the development of single specialty physician networks
 
                                        1
<PAGE>   6
 
   
in combination with practice-based ambulatory surgery centers strategically
located in markets serving the managed care organizations' members.
    
 
   
     While the Company currently owns majority interests in two physician
practices, in May 1998 the Board of Directors approved a plan for the Company to
dispose of its physician practice interests as part of the Company's overall
strategy to exit the practice management business and focus solely on the
development, acquisition and operation of ambulatory surgery centers and
specialty networks.
    
 
     The Company typically owns its surgery centers through limited or general
partnerships or limited liability companies in which a subsidiary of the Company
is a general partner or member and holds a majority interest. The other partners
of the partnerships or members of the limited liability companies are physician
practice groups that generally have offices adjacent to or in close proximity to
the surgery center. In development projects, the capital contributed by the
physicians and the Company, together with bank financing, provides the
partnership or limited liability company with the funds necessary to construct
and equip the surgery center and to provide initial working capital.
 
     The start-up specialty physician networks are also owned through limited
partnerships or limited liability companies in which a subsidiary of the Company
is a general partner or member and holds a majority interest. The other partners
or members are individual physicians who provide the medical services to the
patient population covered by contracts which the network will seek to enter
into with managed care payers. These entities are funded by the Company and the
physicians on a pro rata basis based on their ownership interests.
 
     The Company was a majority-owned subsidiary of American Healthcorp, Inc.
("AHC") from 1992 until December 3, 1997 when AHC distributed to its
stockholders all of its holdings of AmSurg common stock (the "Distribution"). As
a result of the Distribution, the Company became an independent public company.
 
     The Company was incorporated in Tennessee in April 1992. Its principal
executive offices are located at One Burton Hills Boulevard, Nashville,
Tennessee 37215. Its telephone number is (615) 665-1283.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus,
prospective investors should consider carefully the following factors in
evaluating an investment in the Class A Common Stock offered hereby.
 
     Dependence on Acquisition and Development Growth Strategy.  The Company
intends to increase its revenues and earnings, in part, by continuing to develop
and acquire practice-based ambulatory surgery centers and by developing
specialty physician networks. The Company's ability to develop and acquire
additional centers may be affected by its ability to identify suitable
candidates, negotiate and close acquisition and development transactions and
minimize start-up losses for its developed centers. A developed center typically
incurs start-up losses during its initial months of operations and will
experience lower revenues and operating margins than an established center until
the case load grows to a more optimal operating level, which generally is
expected to occur within 12 months after a center opens. There can be no
assurance that the Company will be able to acquire or develop additional surgery
centers, complete the development of centers or achieve satisfactory operating
results at newly developed centers within the expected period of time or develop
and place in operation specialty physician networks. There can also be no
assurance that the assets acquired by the Company in the future will ultimately
produce returns that justify their related investment by the Company. See
"Business -- Strategy; and -- Acquisition and Development of Surgery Centers."
 
     Growth Strategy Requires Substantial Capital Investment.  Capital will be
needed not only for the acquisition of the assets of surgery centers, but also
for their development, effective integration, operation and expansion. The
Company may finance future center development and acquisition by raising
additional capital through debt or equity financings or using shares of its
capital stock for all or a portion of the consideration to be paid in
acquisitions. To the extent that the Company undertakes such financings or uses
capital stock as consideration, the Company's shareholders will experience
future ownership dilution. In the event that the Class A Common Stock does not
maintain a sufficient valuation, or potential acquisition candidates are
unwilling to accept Class A Common Stock as part of the consideration for the
sale of the assets of their businesses, the Company may be required to utilize
more of its cash resources, if available, or rely solely on additional financing
arrangements in order to pursue its acquisition strategy. In such an instance,
if the Company does not have sufficient capital resources, its growth could be
limited and its operations impaired. There can be no assurance that the Company
will be able to obtain financing or that, if available, such financing will be
on terms acceptable to the Company. See "Business -- Strategy."
 
     Ability to Manage Growth.  The Company has recently experienced rapid
growth that has resulted in new and increased responsibilities for management
personnel and has placed increased demands on the Company's management,
operational and financial systems and resources. To accommodate this recent
growth and to compete effectively and manage future growth, the Company will be
required to continue to implement and improve its operational, financial and
management information systems and to expand, train, motivate and manage its
workforce. There can be no assurance that the Company's personnel, systems,
procedures and controls will be adequate to support the Company's operations.
Any failure to implement and improve the Company's operational, financial and
management systems or to expand, train, motivate or manage employees could have
a material adverse effect on the Company's financial condition and results of
operation.
 
     Dependence on Relationships with Physician Partners; Risks of Conflicts of
Interest and Disputes.  The Company's business depends upon, among other things,
the efforts and success of the physicians who provide medical services at the
surgery centers or who are employed by the Company's physician practices and the
strength of the Company's relationship with such physicians. The Company's
business could be adversely affected by any failure of these physicians to
maintain the quality of medical care or otherwise adhere to required
professional guidelines at the Company's surgery centers and physician
practices, any damage to the reputation of a key physician or group of
physicians or the impairment of the Company's relationship with a key physician
or group of physicians. The Company's ownership interests in practice-based
ambulatory surgery centers and specialty physician networks generally are
structured through limited or general partnerships or limited liability
companies. The Company generally maintains a majority interest in each
partnership or limited liability company with physicians or physician practice
groups holding minority limited
 
                                        4
<PAGE>   9
 
partnership interests or serving as minority members. The Company, as owner of
majority interests in such partnerships and limited liability companies, owes a
fiduciary duty to the minority interest holders in such entities and may
encounter conflicts between the respective interests of the Company and the
minority holders. In such cases, the Company's directors are obligated to
exercise reasonable, good-faith judgment to resolve the conflicts and may not be
free to act solely in the best interests of the Company. The Company, in its
role as general partner or as the chief manager of the limited liability
company, generally exercises its discretion in managing the business. Disputes
may arise between the Company and its physician partners with respect to a
particular business decision or regarding the interpretation of the provisions
of the partnership agreement or limited liability company operating agreement,
in which event the agreements provide for arbitration as a dispute resolution
process. No assurances can be given that any such dispute will be resolved or
that any dispute resolution will be on terms satisfactory to the Company.
 
   
     Contingent Obligations.  In the limited partnerships in which the Company
is the general partner, the Company is liable for 100% of the debts and other
obligations of the partnership; however, the partnership agreement requires the
physician partners to guarantee their pro rata share of any indebtedness or
lease agreements to which the partnership is a party, based on the limited
partner's ownership interest in the partnership. The Company also has primary
liability with respect to the bank debt incurred for the benefit of the limited
liability companies, and guarantees are also required of the physician members.
There can be no assurance that a third party lender or lessor would seek
performance of the guarantees rather than seek repayment from the Company of any
obligation of the partnership should it default thereunder or that the physician
partners would have sufficient assets to satisfy their guarantee obligations.
See Note 7 to the Consolidated Financial Statements.
    
 
     Contingent Purchase Obligations.  Upon the occurrence of certain
fundamental regulatory changes, the Company will be obligated to purchase some
or all of the minority interests of the physicians affiliated with the Company
in the partnerships or limited liability companies which own and operate the
Company's surgery centers. The regulatory changes that could create such an
obligation include changes that: (i) make the referral of Medicare and other
patients to the Company's surgery centers by physicians affiliated with the
Company illegal; (ii) create the substantial likelihood that cash distributions
from the partnership or limited liability company to the physicians associated
therewith will be illegal; or (iii) cause the ownership by the physicians of
interests in the partnerships or limited liability companies to be illegal.
There can be no assurance that the Company's existing capital resources would be
sufficient for it to meet the obligation, if it arises, to purchase minority
interests held by physicians in the partnerships or limited liability companies
which own and operate the Company's surgery centers. The determination of
whether such an obligation has been created is made by the concurrence of
counsel for the Company and the physician partners or, in the absence of such
concurrence, by independent counsel having an expertise in healthcare law and
who is chosen by both parties. Accordingly, such determination is not within the
control of the Company. While the Company has structured the purchase
obligations to be as favorable as possible to the Company, the creation of these
obligations could have a material adverse effect on the financial condition and
results of operations of the Company. See "Business -- Acquisition and
Development of Surgery Centers; and -- Government Regulation."
 
     Risks Associated with Capitated Payment Arrangements.  In 1997,
approximately 11% of the Company's total revenues were derived from capitated
payment arrangements. A significant part of the Company's growth strategy
involves assisting its surgery centers, owned physician practices and specialty
physician networks in obtaining capitated managed care contracts and managing
the medical risk associated with such contracts. These capitated managed care
contracts typically are with health maintenance organizations ("HMOs"). Under
such contracts the provider accepts a pre-determined amount per patient per
month, referred to as a "capitation" payment, and in return is responsible for
providing all necessary specified covered services to the patients covered by
the contract, thus shifting much of the risk of providing care from the payer to
the provider. Such an arrangement results in a greater predictability of
revenue, but exposes the provider to the risk of controlling the costs of
providing the services. To the extent that patients covered by such contracts
require more frequent or extensive care than is anticipated, operating margins
may be reduced and the revenue derived from such contracts may be insufficient
to cover the costs of the services provided. There can be no
 
                                        5
<PAGE>   10
 
assurance that the Company will be able to negotiate satisfactory risk-sharing
or capitated arrangements on behalf of its surgery centers, owned physician
practices and specialty physician networks. See "Business."
 
   
     Dependence on Third-Party Reimbursement; Risk of Fee Reductions or
Exclusion from Managed Care Arrangements.  The Company is dependent upon private
and governmental third-party sources of reimbursement for services provided to
patients in its centers and physician practices. In addition to market and cost
factors affecting the fee structure implemented by centers and practices
operated by the Company, numerous Medicare and Medicaid regulations, cost
containment and utilization decisions of third-party payers and other payment
factors over which the Company has no control may adversely affect the amount of
payment a center or practice may receive for its services. On or before January
1, 1999, outpatient surgery services will be reimbursed by Medicare under a
revised prospective payment system, utilizing approximately 100 ambulatory
patient classifications, rather than the eight codes currently utilized. There
can be no assurance that the Company's revenues will not be adversely affected
under this revised payment system. The Company derived approximately 37%, 36%,
37% and 40% of its revenues in 1995, 1996, 1997 and the three months ended March
31, 1998, respectively, from governmental healthcare programs, including
Medicare and Medicaid. The market share growth of managed care has resulted in
substantial competition among providers of services for inclusion in managed
care contracting in some locations. Exclusion from participation in a managed
care contract in a specific location can result in material reductions in
patient volume and reimbursement to a physician practice or to a practice-based
ambulatory surgery center. The Company's financial condition and results of
operations may be adversely affected by fixed fee schedules, capitation payment
arrangements, reduced payments to physicians generally, exclusion from
participation in managed care programs or other changes in payments for
healthcare services. In May 1998 the Company received notification from a payer
with which one of its physician practices and surgery centers has a capitated
contract for professional and surgical gastroenterology services covering
approximately 120,000 lives that the contract would not be renewed beyond the
June 30, 1998 anniversary date of the contract. The payer has advised the
Company that it plans to negotiate a new contract. At this time, the Company
cannot determine the outcome of these negotiations; however, an unfavorable
outcome in these negotiations may have an adverse impact on the Company's
results of operations. This contract contributed $676,000, or 5%, and $617,000,
or 3%, to the Company's consolidated revenues in the three months ended March
31, 1997 and 1998, respectively. See "Business -- Government
Regulation -- Reimbursement" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Sources of Revenues."
    
 
     Risks Associated with Medicare-Medicaid Illegal Remuneration
("anti-kickback") Laws.  Federal anti-kickback laws prohibit the offer, payment,
solicitation or receipt of any form of remuneration in return for the referral
of Medicare or state health program patients or patient care opportunities, or
in return for the purchase, lease or order of items or services that are covered
by Medicare or state health programs. The anti-kickback statute is very broad in
scope and its provisions are not well defined by existing case law or
regulations. Violations of the anti-kickback laws may result in substantial
civil or criminal penalties for individuals or entities. A violation of the
anti-kickback law is a felony punishable by a fine of up to $25,000 or
imprisonment for up to five years, or both. A violation may also result in civil
penalties of up to $10,000 for each violation, plus three times the amount
claimed and exclusion from participation in the Medicare and Medicaid programs.
Such exclusion, if applied to the Company's surgery centers or networks, could
result in significant loss of reimbursement and could have a material adverse
effect on the Company. In July 1991, the Department of Health and Human Services
("DHHS") Inspector General issued final regulations identifying various "safe
harbors," including two related to investment interests, which offer exemption
from the anti-kickback laws. The structure of the partnerships and limited
liability companies operating the Company's surgery centers and physician
networks, as well as certain relationships with physician group practices, do
not satisfy all of the requirements of either of the "investment interest" safe
harbors or the "personal services and management contracts" safe harbor and,
therefore, are not immune from government review or prosecution. Notwithstanding
the Company's belief that the relationships of physician partners with the
Company's surgery centers should not constitute illegal remuneration under the
anti-kickback laws, no assurances can be given that a federal or state agency
charged with enforcement of the anti-kickback laws and similar laws or a private
party might not assert a contrary position or that new federal or state laws
might not be enacted that would cause the physician partners' relationships with
the Company's surgery centers to become illegal or result in
                                        6
<PAGE>   11
 
the imposition of penalties on the Company or certain of its facilities. Even
the assertion of a violation could have a material adverse effect upon the
financial condition and results of operations of the Company. See
"Business -- Government Regulation -- Medicare-Medicaid Illegal Remuneration
Provisions."
 
     Risks Associated with Physician Self-Referral Laws.  At both the state and
federal level, there are legislative restrictions on the ability of a physician
to refer patients to healthcare entities when the physician (or immediate family
member) has a financial relationship, directly or indirectly, with the entity
receiving the referral. The financial relationship giving rise to prohibition on
referrals may be either an ownership or investment interest or a compensatory
arrangement. At the federal level, this legislation (42 USC sec.sec. 1395nn) is
known as the "Stark bill" because of its sponsor, Representative Pete Stark.
Originally, the Stark bill applied only to entities providing clinical
laboratory services. However, as of January 1, 1995, the ban on physician
financial relationships with healthcare entities extended to entities providing
certain defined "designated health services" ("Stark II"). The Company believes
physician ownership of practice-based ambulatory surgery centers to which they
refer patients and physician networks is not prohibited under Stark II or other
similar statutes recently enacted at the state level. However, these statutes
are subject to different interpretations with respect to many important
provisions. Violations of these "self-referral" laws may result in substantial
civil or criminal penalties for individuals or entities, including large civil
monetary penalties and exclusion from participation in the Medicare and Medicaid
programs. Such exclusion, if applied to the Company's surgery centers, could
result in significant loss of reimbursement and could have a material adverse
effect on the Company. There can be no assurances that further judicial or
agency interpretation of existing law or further legislative restrictions on
physician ownership of healthcare entities will not be issued which could have a
material adverse effect upon the financial condition and results of operations
of the Company. See "Business -- Government Regulation -- Prohibition on
Physician Ownership of Healthcare Facilities."
 
   
     Risks Related to Laws Governing Corporate Practice of Medicine.  The laws
of certain states in which the Company operates or may operate in the future do
not permit business corporations to practice medicine, exercise control over
physicians who practice medicine or engage in certain business practices such as
fee-splitting with physicians. The Company is not required to obtain a license
to practice medicine in any jurisdiction in which it owns and operates an
ambulatory surgery center because the surgery centers are not engaged in the
practice of medicine. The physician partners who utilize the center are
individually licensed to practice medicine. The group practices, with the
exception of the two physician practices majority owned by the Company, are not
affiliated with the Company other than through the physicians' ownership in the
partnerships and limited liability companies that own the surgery centers. The
Company owns a majority interest in two group practices in Florida, a state
which permits physicians to practice medicine through an entity that is not
wholly-owned by physicians. A recent ruling by the Florida Board of Medicine
that an agreement between a physician practice and a practice management company
constituted impermissible fee-splitting, if upheld on judicial appeal, would
cause the Company to restructure its relationship with one of the two group
practices. The Company does not believe that any such restructuring would have a
material adverse effect on the Company. There can be no assurance, however, that
future changes in the law in Florida will not require the Company to restructure
its ownership of these group practices and that such restructuring will not have
a material adverse effect on the Company. See "Business -- Government
Regulation -- Corporate Practice of Medicine."
    
 
     Risks of Potential Applicability of Insurance Regulations and Antitrust
Laws.  Laws in all states regulate the business of insurance and the operations
of HMOs. Many states also regulate the establishment and operation of networks
of healthcare providers. The Company believes that its operations are in
compliance with these laws in the states in which it currently does business.
The National Association of Insurance Commissioners (the "NAIC") has endorsed a
policy proposing the state regulation of risk assumption by healthcare
providers. The policy proposes prohibiting providers from entering into
capitated payment or other risk sharing contracts except through HMOs or
insurance companies. Several states have adopted regulations implementing the
NAIC policy in some form. In states where such regulations have been adopted,
healthcare providers will be precluded from entering into capitated contracts
directly with employers and benefit plans other than HMOs or insurance
companies.

     The Company and its affiliated physician groups may in the future enter
into additional contracts with managed care organizations, such as HMOs, whereby
the Company and its affiliated physician groups would assume risk in connection
with providing healthcare services under capitation arrangements. If the Company
or its affiliated physician groups are considered to be in the business of
insurance as a result of entering into such risk sharing arrangements, they
could become subject to a variety of regulatory and licensing requirements
applicable to insurance companies or HMOs, which could have a material adverse
effect on the Company's ability to enter into such contracts. See
"Business -- Government Regulation -- Insurance and Antitrust Laws."
 
     With respect to managed care contracts that do not involve capitated
payments or some other form of financial risk sharing, federal and state
antitrust laws restrict the ability of healthcare provider networks such as the
Company's specialty physician networks to negotiate payments on a collective
basis.
 
     Risks of Compliance with Other Government Regulation.  All facets of the
healthcare industry are highly regulated at the federal and state levels. The
Company's ability to be profitable may be adversely affected by licensing and
certification requirements, reimbursement restrictions or reductions and other
governmental regulatory factors. In addition, the Company's ability to expand
its services in the future may be adversely affected by health planning laws,
including CON requirements, at the state and/or federal level. A number of other
initiatives have developed during the past several years to reform various
aspects of the healthcare system in the United States. There can be no assurance
that current or future legislative initiatives or government regulation will not
have a material adverse effect on the financial condition or results of
operations of the Company or reduce the demand for its services. See
"Business -- Government Regulation -- CONs and State Licensing."
 
   
     Prior Reliance on AHC.  The Company historically relied upon AHC for
certain corporate management, administrative and accounting services. The
Company is now responsible for maintaining its own management, administrative
and accounting functions, except for certain financial and accounting services
provided by AHC on a transitional basis until December 1998 pursuant to the
Administrative Services Agreement (as defined herein) and for certain advisory
services provided by members of AHC senior management pursuant to advisory
agreements expiring in December 1999. In particular, Thomas G. Cigarran, who was
the Chairman and Chief Executive Officer of the Company, no longer serves as an
officer of the Company, although he continues to serve as Chairman of the Board
of Directors and is now an advisor to the Company. Henry D. Herr, who was Vice
President and Secretary of the Company, now serves as a director and an advisor
to the Company, but no longer serves as an officer of the Company. See "Certain
Relationships and Related Transactions."
    
 
   
     Risks Related to Intangible Assets.  As a result of purchase accounting for
the Company's various acquisition transactions, the Company's balance sheet at
March 31, 1998 contains an intangible asset designated as excess of cost over
net assets of purchased operations totaling $44.1 million. Using an amortization
period of 25 years, amortization expense relating to this intangible asset will
be approximately $1.9 million per year. Purchases of interests in practice-based
surgery centers that result in the recognition of additional intangible assets
would cause amortization expense to increase further.
    
 
   
     On an ongoing basis, the Company evaluates, based upon projected
undiscounted cash flows, whether facts and circumstances indicate any impairment
of value of intangible assets and if the amortization period continues to be
appropriate. As the underlying facts and circumstances subsequent to the date of
acquisition can change, there can be no assurance that the value of such
intangible assets will be realized by the Company. Any determination that a
significant impairment has occurred would require the write-off of the impaired
portion of unamortized intangible assets, which could have a material adverse
effect on the Company's results of operations. In that regard, in 1997 the
Company recorded an impairment loss which ultimately resulted in a net loss of
$2.0 million in connection with one partnership and in the second quarter of
1998 the Company expects to record a charge of $3.6 million net of income tax
benefit in conjunction with its plan to exit the physician practice management
business. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and Notes 4 and 16 to the Consolidated Financial
Statements.

     Proposed Treasury Regulation Regarding Tax Deduction for Amortization of
Goodwill.  Effective on August 10, 1993, Section 197 of the Internal Revenue
Code of 1986, as amended (the "Code"), was enacted to allow goodwill and other
intangible assets purchased after that date to be amortized over a fifteen-year
period for tax purposes. Previously, no tax deduction was allowed for purchases
of goodwill. On January 16, 1997, the Internal Revenue Service (the "IRS")
published proposed regulations regarding Section 197 amortization of intangible
assets including goodwill. The proposed regulations cover certain
"anti-churning" provisions which deny a deduction for goodwill amortization in
several situations, including situations in which the taxpayer acquired the
goodwill in a transaction immediately before or after which the seller of the
goodwill is related to the acquiring taxpayer. The anti-churning rules are
designed to prevent taxpayers from converting existing goodwill for which an
amortization deduction would not have been allowable prior to the enactment of
Section 197 into an asset with respect to which Section 197 would currently
allow an amortization deduction. These proposed regulations do not specifically
contain an exception for the form of transaction that the Company has utilized
in its acquisition of interests in practice-based ambulatory surgery centers and
interests in physician practices. However, because the goodwill for which the
Company has been claiming amortization deductions was purchased by the Company
from unrelated parties after the effective date of Section 197 and, as per
agreement with the sellers, the tax deduction for goodwill amortization is
specifically allocated exclusively to the Company (and therefore, the seller
receives no tax benefit from the amortization of the goodwill), the Company
believes that the proposed regulations should not affect the Company's
amortization deductions. Together with other taxpayers similarly affected, the
Company will vigorously attempt to persuade the IRS to revise the proposed
regulations to recognize that the methodology utilized by the Company is
consistent with the intent of Section 197 and the anti-churning rules and to
preserve the amortization deduction with respect to the Company's acquired
goodwill. However, there can be no assurance that the proposed regulations will
be amended or modified by the IRS. If the proposed regulations are adopted as
currently written, it will not be clear whether the Company would be entitled to
the deduction for the amortization of goodwill associated with the purchase of
interests in practice-based surgery centers and physician practices and these
deductions could be subject to challenge by the IRS. Loss of these tax
deductions would have a material adverse effect on the Company's results of
operations. Due to the lengthy public hearing and adoption process, the Company
is not able to estimate a date by which the IRS will take action on the proposed
regulations.
 
     Competition.  The healthcare business is highly competitive. There are
other companies in the same or similar business of developing, acquiring and
operating practice-based ambulatory surgery centers, specialty physician
networks and physician practices, or who may decide to enter the practice-based
ambulatory surgery center business, the development of specialty physician
networks or the acquisition of physician practices, who have greater financial,
research, marketing and staff resources than the Company. In addition, the
Company competes with other healthcare providers for contracting with managed
care payers in each of its markets. There can be no assurance the Company can
compete effectively with such entities. See "Business -- Competition."
 
     Risks Relating to Year 2000 Compliance.  Many existing computer software
programs and operating systems were designed such that the year 1999 is the
maximum date that many computer systems will be able to process. The Company is
addressing the potential problems posed by this limitation in its systems
software to assure that the Company is prepared for the Year 2000. The Company
also intends to seek verification from third parties with which it conducts
material business, such as payers, that such parties will be Year 2000
compliant. If modifications and conversions to deal with Year 2000 issues are
not completed on a timely basis by the Company or by third parties with which
the Company conducts material business, such issues may have a material adverse
effect on the results of operations of the Company. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Year 2000."
 
   
     Shares Eligible for Future Sale.  Upon completion of the Offering, the
Company will have outstanding an aggregate of 9,462,391 shares of Class A Common
Stock (10,017,391 shares if the Underwriters' over-allotment option is exercised
in full) and 4,787,131 shares of Class B Common Stock. The 3,700,000 shares of
Class A Common Stock sold in the Offering will be freely tradeable without
restriction under the Securities Act of 1933, as amended (the "Securities Act")
unless acquired by "affiliates" of the Company as that term is
    
 
                                        9

defined in Rule 144 under the Securities Act, which shares would be subject to
the resale limitations of Rule 144. In addition, the 743,000 shares of Class A
Common Stock that were issued to holders of AHC common stock in the Distribution
are freely tradeable without restriction or further registration under the
Securities Act, unless held by affiliates of the Company (which shares also
would be subject to certain resale limitations and other restrictions under Rule
144 described below).
 
   
     Of the remaining 5,019,391 outstanding shares of Class A Common Stock,
4,753,298 have not been issued in transactions registered under the Securities
Act, which means that under current law, absent registration or an exemption
from registration other than Rule 144, such shares are "restricted securities"
as that term is defined in Rule 144 under the Securities Act and are eligible
for sale or transfer only in accordance with Rule 144. Substantially all of
these shares of Class A Common Stock have met the one-year holding period
requirement of Rule 144, and therefore are eligible for sale thereunder.
    
 
     Anti-takeover Provisions.  Certain provisions of the Company's Amended and
Restated Charter (the "Charter") and Amended and Restated Bylaws (the "Bylaws")
establish staggered terms for members of the Company's Board of Directors and
include advance notice procedures for shareholders to nominate candidates for
election as directors of the Company and for shareholders to submit proposals
for consideration at shareholders' meetings. In addition, the Company is subject
to the Tennessee Business Combination Act (the "Combination Act") of the
Tennessee Business Corporation Act ("TBCA") which limits transactions between a
publicly held company and "interested shareholders" (generally, those
shareholders who, together with their affiliates and associates, own 10% or more
of the voting power of any class or series of a company's stock). The
restrictions of the Combination Act would not apply to those who were
"interested shareholders" prior to the consummation of the Offering. These
provisions of the TBCA may have the effect of deterring certain potential
acquirors of the Company. The Company's Charter provides for 5,000,000
authorized shares of preferred stock, the rights, preferences, qualifications,
limitations and restrictions of which may be fixed by the Board of Directors
without any further action by the shareholders. See "Description of Capital
Stock -- Certain Provisions of the Charter, Bylaws and Tennessee Law."

     On May 18, 1998, the last reported sale prices for the Class A Common Stock
and the Class B Common Stock were $10.13 and $10.13 per share, respectively. The
Company estimates that as of March 15, 1998, there were approximately 160
holders of record and 2,084 beneficial owners of the Class A Common Stock and 95
holders of record and 2,124 beneficial owners of the Class B Common Stock.
    
 
     The Company has never declared or paid a cash dividend on its Common Stock.
It is the current policy of the Board of Directors to retain all earnings to
support operations and to finance expansion of the Company's business;
therefore, the Company does not anticipate declaring or paying dividends on the
Common Stock in the foreseeable future. The declaration and payment of cash
dividends in the future will be at the Board of Directors' discretion and will
depend on the Company's earnings, financial condition, capital needs and other
factors deemed pertinent by the Board of Directors, including limitations, if
any, on the payment of dividends under state law and any then-existing credit
agreement. Pursuant to the terms of the Company's bank credit facility, the
Company is prohibited from declaring or paying cash dividends.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the Class A Common Stock
offered hereby, at an assumed public offering price of $10.13 per share, are
estimated to be $35.1 million ($40.4 million if the Underwriters' over-allotment
option is exercised in full), after deduction of the underwriting discount and
estimated offering expenses payable by the Company. Approximately $33.1 million
of the net proceeds will be used to repay borrowings under the revolving credit
facility of the Company's Third Amended and Restated Loan Agreement (the "Loan
Agreement"). Borrowings under the Loan Agreement mature in January 2001, and
bear interest at a rate equal to, at the Company's option, the prime rate or
LIBOR plus a spread of 1.0% to 2.25%, depending upon borrowing levels. The Loan
Agreement also provides for a fee ranging between .15% and .40% of unused
commitments based on borrowing levels. The Company will have $50.0 million
available for borrowing under the Loan Agreement upon completion of the Offering
and application of the net proceeds. The indebtedness under the Loan Agreement
was incurred primarily to finance the development and acquisition of surgery
centers, and the Company intends to continue to utilize borrowings under the
Loan Agreement for the same purpose. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources." The Company intends to use the balance of the net proceeds for
working capital and for other general corporate purposes, including the
development and acquisition of surgery centers. Pending such uses, the net
proceeds will be invested in short-term, investment-grade or government,
interest-bearing securities.

    The following table sets forth selected consolidated financial data which
have been derived from the Company's consolidated financial statements. The
financial statements at and for the periods ended December 31, 1993 through 1997
have been audited. The pro forma combined statement of operations data for the
year ended December 31, 1997 and the three months ended March 31, 1998 set forth
below reflect the effect of six acquisitions in 1997 and three acquisitions in
1998 occurring subsequent to the beginning of the period as if such transactions
were completed at January 1, 1997. The pro forma balance sheet data at March 31,
1998 set forth below reflect the effect of an acquisition of a surgery center
occurring subsequent to March 31, 1998 as if such transaction had been completed
as of March 31, 1998. Comparability of data on a year-to-year basis is affected
by the number of centers acquired or opened in each year. All the information
set forth below should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the Consolidated
Financial Statements and related notes included elsewhere herein. See "Index to

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     "Management's Discussion and Analysis of Financial Condition and Results of
Operations" contains forward-looking statements. These statements, which have
been included in reliance on the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995, involve risks and uncertainties. The
Company's actual operations and results may differ materially from the results
discussed in the forward-looking statements. Factors that might cause such a
difference include, but are not limited to, the Company's ability to enter into
partnership or operating agreements for new practice-based ambulatory surgery
centers and new specialty physician networks; its ability to identify suitable
acquisition candidates and negotiate and close acquisition transactions; its
ability to obtain the necessary financing or capital on terms satisfactory to
the Company in order to execute its expansion strategy; its ability to manage
growth; its ability to contract with managed care payers on terms satisfactory
to the Company for its existing centers and its centers that are currently under
development; its ability to obtain and retain appropriate licensing approvals
for its existing centers and centers currently under development; its ability to
minimize start-up losses of its development centers; its ability to maintain
favorable relations with its physician partners; and its ability to sell the two
physician practices.
    
 
OVERVIEW
 
   
     The Company develops, acquires and operates practice-based ambulatory
surgery centers in partnership with physician practice groups. As of March 31,
1998, the Company owned a majority interest (51% or greater) in 41 surgery
centers, owned a minority interest in one surgery center, owned a majority
interest (60% or greater) in two physician practices and had established and was
the majority owner (51%) of five start-up specialty physician networks.
    
 
     The Company operated as a majority-owned subsidiary of AHC from 1992 until
the Distribution on December 3, 1997. Prior to the Distribution, the Company
effected a recapitalization pursuant to which every three shares of the
Company's then outstanding common stock were converted into one share of Class A
Common Stock. Immediately following the Recapitalization, AHC exchanged a
portion of its shares of Class A Common Stock for shares of Class B Common
Stock. The principal purpose of the Distribution was to enable the Company to
have access to debt and equity capital markets as an independent, publicly
traded company. Upon the Distribution, the Company became a publicly traded
company.
 
   
     The following table presents the changes in the number of surgery centers
in operation and centers under development for the periods indicated. A center
is deemed to be under development when a partnership or limited liability
company has been formed with the physician group partner to develop the center.

     Thirty-two of the surgery centers in operation as of March 31, 1998 perform
gastrointestinal endoscopy procedures; eight centers perform ophthalmology
procedures; one center performs orthopaedic procedures; and one center performs
ophthalmology, urology, general surgery and otolaryngology procedures. The other
partner or member in each partnership or limited liability company is in each
case an entity owned by physicians who perform procedures at the center.
    
 
                                       14
<PAGE>   19
 
   
     In addition, the Company has a majority interest in two physician practices
which were acquired in January 1996 and January 1997, the other partners of
which are entities owned by the principal physicians who provide professional
medical services to patients of the practices. In May 1998, the Company's Board
of Directors approved a plan to dispose of the Company's interests in these two
specialty physician practices as part of an overall strategy to exit the
practice management business and focus solely on the development, acquisition
and operation of ambulatory surgery centers and specialty networks. Accordingly,
the Company will record a charge of $3.6 million, net of income tax benefit of
$1.8 million, in the second quarter of 1998 for the estimated loss on the
disposal of these assets. Although the Company is currently in negotiations
regarding the possible sale of one of the two practices, there are no definitive
agreements or arrangements with regard thereto. Therefore, there can be no
assurance that the Company will sell these operations; however, the Company
believes that the estimated disposal loss will be adequate in the sale of the
practices. See Note 16 of the Consolidated Financial Statements.
    
 
   
     The start-up specialty physician networks are owned through limited
partnerships and limited liability companies in which the Company owns a
majority interest. The other partners or members are individual physicians who
will provide the medical services to the patient population covered by the
contracts the network will seek to enter into with managed care payers. The
Company does not expect that the specialty physician networks alone will be a
significant source of income for the Company. These networks were and will be
formed in selected markets primarily as a contracting vehicle for certain
managed care arrangements to generate revenues for the Company's practice-based
surgery centers. As of March 31, 1998, one network had secured a managed care
contract and was operational.
    
 
     The Company intends to expand primarily through the development and
acquisition of additional practice-based ambulatory surgery centers in targeted
surgical specialties. In addition, the Company believes that its surgery
centers, combined with the Company's relationships with specialty physician
practices in the surgery centers' markets, will provide the Company with other
opportunities for growth from specialty network development. By using its
surgery centers as a base to develop specialty physician networks that are
designed to serve large numbers of covered lives, the Company believes that it
will strengthen its market position in contracting with managed care
organizations.
 
     While the Company generally owns 51% to 70% of the entities that own the
surgery center or physician group practice, the Company's consolidated
statements of operations include 100% of the results of operations of the
entities, reduced by the minority partners' share of the net earnings or loss of
the surgery center/practice entities.
 
SOURCES OF REVENUES
 
     The Company's principal source of revenues is a facility fee charged for
surgical procedures performed in its surgery centers. This fee varies depending
on the procedure, 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 patient's surgeon,
anesthesiologist or other attending physicians, which are billed directly to
third-party payers by such physicians. The Company's other significant source of
revenues is the fee for physician services performed by the two physician group
practices in which the Company owns a majority interest.
 
   
     Practice-based ambulatory surgery centers and physician practices such as
those in which the Company owns a majority interest depend upon third-party
reimbursement programs, including governmental and private insurance programs,
to pay for services rendered to patients. The Company derived approximately 37%,
36%, 37% and 40% of its net revenues from governmental healthcare programs,
including Medicare and Medicaid, in 1995, 1996, 1997 and the three months ended
March 31, 1998, respectively. The Medicare program currently pays ambulatory
surgery centers and physicians in accordance with fee schedules which are
prospectively determined.
    
 
   
     Approximately 10%, 11% and 9% of the Company's revenues for 1996, 1997 and
the three months ended March 31, 1998, respectively, were generated by capitated
payment contracts with HMOs. These revenues generally were attributable to
contracts held by physician practices and a surgery center in which the
    
                                       15
<PAGE>   20
 
   
Company holds a majority interest. These contracts require the practices to
provide specialty physician and certain outpatient surgery services for the HMO
members on an exclusive basis. These contracts do not require the practices to
provide or to be at risk for hospital or other ancillary services such as
laboratory or imaging services. The services required by these contracts are
provided almost solely by surgery centers and the physician practices in which
the Company owns a majority interest. Because the Company is only at risk for
the cost of providing relatively limited healthcare services to these HMO
members, the Company's risk of overutilization by HMO members is limited to the
cost of the physician's time and the supply, drug and nursing staff expense
required for outpatient surgery. In May 1998 the Company received notification
from a payer with which one of its physician practices and surgery centers has a
capitated contract for professional and surgical gastroenterology services
covering approximately 120,000 lives that the contract would not be renewed
beyond the June 30, 1998 anniversary date of the contract. The payer has advised
the Company that it plans to negotiate a new contract. At this time, the Company
cannot determine the outcome of these negotiations; however, an unfavorable
outcome in these negotiations may have an adverse impact on the Company's
results of operations. This contract contributed $676,000, or 5%, and $617,000,
or 3%, to the Company's consolidated revenues in the three months ended March
31, 1997 and 1998, respectively. See Note 16 of the Consolidated Financial
Statements.
    
 
   
     The Company's sources of revenues as a percentage of total revenues for the
periods indicated are as follows:

  Three Months Ended March 31, 1998 Compared to Three Months Ended March 31,
1997
    
 
   
     Revenues were $17.8 million in the three months ended March 31, 1998, an
increase of $5.2 million, or 42%, over revenues in the comparable 1997 period.
The increase is primarily attributable to additional centers in operation in the
three months ended March 31, 1998. Same-center revenues in the three months
ended March 31, 1998, increased by 14%. Same-center revenue growth resulted
primarily from increased procedure volume. The Company anticipates further
revenue growth during 1998 as a result of additional start-up and acquired
centers expected to be placed in operation and from same-center revenue growth,
net of a revenue reduction due to the expected disposition of the physician
practices and any possible adverse impact of the renegotiated capitated
contract, as discussed above.
    
 
   
     Salaries and benefits expense was $5.4 million in the three months ended
March 31, 1998, an increase of $1.4 million, or 35%, over salaries and benefits
expense in the comparable 1997 period. Other operating expenses were $6.4
million in the three months ended March 31, 1998, an increase of $1.9 million,
or 43%, over other operating expenses in the comparable 1997 period. These
increases resulted primarily from additional centers in operation, from an
increase in corporate staff primarily to support growth in the number of centers
in operation and anticipated future growth and from additional corporate costs
associated with being a publicly traded company.
    
 
   
     The Company anticipates further increases in operating expenses in 1998,
primarily due to additional start-up centers and acquired centers expected to be
placed in operation, offset by the expected elimination of physician practice
operating expenses upon the planned disposal of these practices. Typically, a
start-up center will incur start-up losses during its initial months of
operation and will experience lower revenues and operating margins than an
established center until its case load increases to a more optimal operating
level, which generally is expected to occur within 12 months after a center
opens.
    
 
   
     Depreciation and amortization expense increased $481,000, or 44%, in the
three months ended March 31, 1998, over the comparable 1997 period, primarily
due to 13 additional surgery centers in operation in the three months ended
March 31, 1998 compared to the comparable 1997 period.
    
 
   
     During the three months ended March 31, 1998, the Company incurred a net
loss of $43,000 related to the sale of a surgery center to an unaffiliated third
party. The Company does not believe that this sale will have a significant
impact on the Company's future ongoing results of operations. During the
comparable 1997 period, the Company recorded an impairment loss of $2.3 million,
which ultimately resulted in a net loss of $2.0 million, in connection with a
partnership that operated two surgery centers.
    
 
   
     The minority interest in earnings in the three months ended March 31, 1998,
increased by $860,000, or 44%, over the comparable 1997 period primarily as a
result of minority partners' interests in earnings of surgery centers recently
added to operations and from increased same-center profitability.
    
 
   
     Interest expense increased $185,000, or 60%, during the three months ended
March 31, 1998, over the comparable 1997 period due to debt assumed or incurred
in connection with additional acquisitions of interests in surgery centers,
together with the interest expense associated with newly opened start-up surgery
centers financed partially with bank debt.
    
 
   
     The Company recognized income tax expense of $467,000 in the three months
ended March 31, 1998, compared to $329,000 in the comparable 1997 period. In the
three months ended March 31, 1997, the Company recognized no tax benefit
associated with the net loss on sale of assets. The Company's effective tax rate
in both periods was 40% of earnings prior to the impact of the net loss on sale
of assets and differed from the federal statutory income tax rate of 34%
primarily due to the impact of state income taxes.
    
 
   
     Accretion of preferred stock discount in the three months ended March 31,
1997 resulted from the issuance during November 1996 of redeemable preferred
stock with a redemption amount of $3.0 million. The preferred stock was recorded
at its fair market value, net of issuance costs. From the time of issuance, the
Series A Redeemable Preferred Stock (the "Series A Preferred Stock") has been
accreted toward its redemption value, including potential dividends, over the
redemption term. During the three months ended March 31, 1998, the holders of
this series of preferred stock elected to convert their preferred shares into
    
 
                                       17
<PAGE>   22
 
   
380,952 shares of Class A Common Stock pursuant to the provisions of the
Company's Charter using a conversion ratio based on the market price of the
Company's Class A Common Stock. Accordingly, the Company will no longer record
accretion of preferred stock discount.
    
 
  Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
   
     Revenues were $57.4 million in 1997, an increase of $22.5 million, or 65%,
over revenues in 1996. The increase is primarily attributable to additional
centers in operation in 1997 and the acquisition of a urology physician practice
on January 1, 1997. Excluding the three centers which were disposed as described
below, same-center revenues in 1997 increased by 6%. Same-center growth resulted
from increased case volume and increases in fees.
    
 
     Salaries and benefits expense was $17.4 million in 1997, an increase of
$5.7 million, or 50%, over salaries and benefits expense in 1996. Other
operating expenses were $20.4 million in 1997, an increase of $8.8 million, or
76%, over other operating expenses in 1996. This increase resulted primarily
from additional centers in operation, the acquisition of the interest in the
urology physician practice and from an increase in corporate staff primarily to
support growth in the number of centers in operation and anticipated future
growth. Salaries and benefits expense and other operating expenses in the
aggregate as a percentage of revenues remained comparable at 66% in 1997 and
1996. However, salaries and benefits expense as a percentage of revenues
decreased in 1997 while other operating expenses as a percentage of revenues
increased proportionately in 1997 compared to 1996, primarily due to the
addition of contracted physician service expense for the physician practice
acquired in January 1997 within other operating expenses.
 
   
     Depreciation and amortization expense increased $1.9 million, or 65%, in
1997 over 1996, primarily due to 12 additional surgery centers and one physician
practice in operation in 1997 compared to 1996.
    
 
     Included in net loss on sale of assets in 1997 is a loss of approximately
$2.0 million from the disposition of the Company's investment in a partnership
that owned two surgery centers acquired in 1994. Various disagreements with the
sole physician partner over the operation of these centers had adversely
affected the operations of these centers. After a series of discussions and
attempts to resolve these differences, the Company determined that the partners
could not resolve their disagreements, and that, as a result, the carrying value
of the assets associated with this partnership would not likely be fully
recovered. The Company projected the undiscounted cash flows from these centers
and determined these cash flows to be less than the carrying value of the
long-lived assets attributable to this partnership. Accordingly, an impairment
loss equal to the excess of the carrying value of the long-lived assets over the
present value of the estimated future cash flows was recorded in the first
quarter of 1997 in accordance with Statement of Financial Accounting Standards
No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed of." In September 1997, the Company sold its interest in
the partnership assets to its physician partner and recognized a partial loss
recovery. The Company believes that it has good relationships with its other
physician partners and that the loss attributable to the partnership discussed
above resulted from a unique set of circumstances.
 
     In addition, net loss on sale of assets includes a pretax gain of
approximately $460,000 from the sale in July 1997 of a surgery center building
and equipment which the Company had leased to a gastrointestinal physician
practice. Concurrently with the sale, the Company terminated its management
agreement with the physician practice for the surgery center in which the
Company had no ownership interest but had managed since 1994.
 
     The minority interest in earnings in 1997 increased by $3.7 million, or
67%, over 1996 primarily as a result of minority partners' interest in earnings
at surgery centers recently added to operations and from increased same-center
profitability.
 
     Interest expense increased $745,000, or 92%, in 1997 over 1996 due to debt
assumed or incurred in connection with additional acquisitions of interests in
surgery centers and a physician practice, together with the interest expense
associated with newly opened start-up surgery centers financed partially with
bank debt.
 
     Distribution cost in 1997 represents costs incurred by the Company related
to effecting the Distribution.
                                       18
<PAGE>   23
 
     The Company recognized income tax expense of $1.8 million in 1997, compared
to $1.0 million in 1996. The Company has recognized no tax benefit associated
with distribution cost and net loss on sale of assets, while certain tax aspects
of the gain transaction recorded in July 1997 resulted in income tax expense of
approximately $100,000. The Company's effective tax rate in both periods was 40%
of earnings prior to the impact of distribution cost and net loss on sale of
assets and differed from the federal statutory income tax rate of 34%, primarily
due to the impact of state income taxes.
 
     Accretion of preferred stock discount resulted from the issuance during
November 1996 of redeemable preferred stock with a redemption amount of $3.0
million. The preferred stock was recorded at its fair market value, net of
issuance costs. From the time of issuance, the Series A Preferred Stock has been
accreted toward its redemption value, including potential dividends, over the
redemption term. Subsequent to December 31, 1997, using a conversion ratio based
on the market price of the Company's Class A Common Stock, the holders of this
preferred stock elected to convert their preferred shares into 380,952 shares of
Class A Common Stock pursuant to the provisions of the Company's Charter.
 
  Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
     Revenues were $34.9 million in 1996, an increase of $12.5 million, or 56%,
over revenues in 1995. The increase resulted primarily from the growth in the
number of surgery centers in operation, the acquisition of a majority interest
in a physician practice as of January 31, 1996 and an increase of 14% in
same-center revenues for the 15 centers in operation since January 1, 1995.
 
     Salaries and benefits expense increased by $5.4 million, or 86%, while
other operating expenses increased by $4.0 million, or 53%, in 1996 over 1995.
These increases resulted primarily from the acquisition of the interest in a
physician practice, additional centers in operation and an increase in corporate
staff primarily to support growth in the number of centers in operation and
anticipated future growth. Salaries and benefits expense and other operating
expenses represented in the aggregate approximately 66% of revenues for 1996 as
compared to approximately 62% of revenues for 1995. Physician group practices
generally have lower operating margins than ambulatory surgery centers. Because
the physician practice has both greater revenues and greater operating expenses
as a percentage of revenues than any single center, its acquisition had a
disproportionately large impact on operating margins.
 
     Depreciation and amortization expense increased $603,000, or 25%, in 1996
over 1995, primarily due to the acquisition of majority interests in additional
surgery centers, the acquisition of the interest in a physician practice and new
start-up surgery centers placed in operation. The increase of $182,000, or 29%,
in interest expense in 1996 over 1995 is primarily attributable to debt assumed
or incurred in connection with additional acquisitions of interests in surgery
centers and a physician practice, together with the interest expense associated
with newly opened start-up surgery centers financed partially with bank debt.
 
     Minority partners' interest in center earnings in 1996 rose to $5.4 million
from $3.9 million in 1995, an increase of 38%, primarily as a result of minority
partners' interest in earnings at surgery centers added to operations and from
increased same-center profitability.
 
     Income tax expense increased 70% in 1996 to $985,000 as a result of
increased income before income taxes and an increase in the Company's effective
income tax rate to 40% from 36%. The increase in the effective income tax rate
resulted from the utilization of prior period net operating loss carryforwards
during 1995. The difference between the federal statutory income tax rate of 34%
and the Company's effective income tax rates resulted primarily from the
utilization of prior period net operating loss carryforwards in 1995 and the
impact of state income taxes.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     At March 31, 1998 and December 31, 1997, the Company had working capital of
$11.2 million and $9.3 million compared to $4.8 million and $4.7 million in the
comparable prior periods. Operating activities for 1997 generated $4.0 million
in cash flow from operations compared to $3.8 million in 1996. Operating
activities for the three months ended March 31, 1998 generated $1.1 million in
cash flow from operations compared to $1.6 million in the comparable 1997
period. Cash and cash equivalents at March 31, 1998 and December 31, 1997 were
$3.8 million and $3.4 million compared to $2.4 million and $3.2 million in the
comparable prior periods.
    
 
   
     During 1997 the Company used $12.6 million to acquire interests in five
additional practice-based ambulatory surgery centers and a urology physician
practice. In addition, the Company made capital expenditures primarily for new
start-up surgery centers and for new or replacement property at existing centers
which totaled $10.6 million in 1997, of which $3.0 million was funded from the
capital contributions of the Company's minority partners. The Company used its
cash flow from operations and net borrowings on long-term debt of $14.1 million
to fund its acquisition and development obligations. During the three months
ended March 31, 1998, the Company used $4.6 million to acquire interests in two
additional practice-based ambulatory surgery centers. In addition, the Company
made capital expenditures primarily for new start-up surgery centers and for new
or replacement property at existing centers which totaled $2.4 million in the
three months ended March 31, 1998, of which $804,000 was funded from the capital
contributions of the Company's minority partners. The Company used its cash flow
from operations and net borrowings on long-term debt of $4.8 million to fund
these acquisitions and development obligations.
    
 
   
     During 1997 the Company received cash proceeds of $2.0 million from the
sale of a surgery center building and equipment and the sale of a partnership
interest in two surgery centers. In addition, the Company received proceeds of
$524,000 from the sale of common stock to its minority partners in 1997. During
the three months ended March 31, 1998, the Company received cash proceeds of
$641,000 from the sale of a surgery center. In addition, the Company received
proceeds of $18,000 from the issuance of common stock.

     At March 31, 1998, the Company's partnerships and limited liability
companies had unfunded construction and equipment purchase commitments for
centers under development of approximately $2.0 million, of which the Company
expects that approximately $943,000 will be borrowed under the Loan Agreement
(and guaranteed on a pro rata basis by the physicians), and that the remaining
amount will be provided by the Company and the physician partners in proportion
to their respective ownership interests in the partnerships and limited
liability companies. The Company intends to fund its portion out of future cash
flows from operations.
    
 
   
     Under the terms of the Loan Agreement, all borrowings outstanding under the
Company's term loan were converted to its revolving credit facility. At March
31, 1998, borrowings under the Loan Agreement were $27.6 million, are due in
January 2001 and are guaranteed by the wholly owned subsidiaries of the Company,
and in some instances, are secured by the underlying assets of certain developed
centers or the stock of the wholly owned subsidiaries of the Company. The Loan
Agreement permits the Company to borrow up to $50.0 million to finance the
Company's acquisition and development projects at a rate equal to, at the
Company's option, the prime rate or LIBOR plus a spread of 1.0% to 2.25%,
depending upon borrowing levels. The Loan Agreement also provides for a fee
ranging between .15% and .40% of unused commitments based on borrowing levels.
The Loan Agreement also prohibits the payment of dividends and contains
covenants relating to the ratio of debt to net worth, operating performance and
minimum net worth. The Company was in compliance with all covenants at March 31,
1998.
    
 
   
     On November 20, 1996, the Company issued shares of its Series A Preferred
Stock and Series B Preferred Stock to certain unaffiliated institutional
investors for net cash proceeds of approximately $5.0 million. The purpose of
the offering was to fund the acquisition and development of surgery centers and
to provide other working capital as needed prior to being in position to access
capital markets as an independent public company. The Series A Preferred Stock,
which had a liquidation value of $3.0 million and was subject to redemption at
any time at the option of the Company, upon the occurrence of certain events and
in 2002 at the option of the holders, was converted during the three months
ended March 31, 1998 by its holders into 380,952 shares of Class A Common Stock
using a conversion ratio based on market price of the Class A Common Stock
pursuant to the provisions of the Company's Charter. Upon the occurrence of
certain events, including an Initial Public Offering (as that term is defined in
the Company's Charter), the Series B Preferred Stock will automatically convert
into a number of shares of Class A Common Stock that approximates 6% of the
equity of the Company determined as of November 20, 1996, with that percentage
being ratably increased to 8% of the equity of the Company if a triggering event
has not occurred by November 20, 2000. This Offering, if consummated, will
constitute such a triggering event, and the Series B Preferred Stock will
convert into approximately 607,500 shares of Class A Common Stock. If a
triggering event does not occur by November 20, 2002, the holders of the Series
B Preferred Stock will have the right to sell such preferred stock to the
Company on an as-if-converted basis at the current market price of the
underlying Class A Common Stock.
    
 
     Historically, the Company depended on AHC for the majority of its equity
financing. A principal purpose of the Distribution was to permit the Company to
have access to public debt and equity capital markets as an independent public
company. While the Company anticipates that its operating activities will
continue to provide increased revenues and cash flow, the Company will require
additional financing in order to fund its development and acquisition plans and
to achieve its long-term strategic growth plans. This additional financing could
take the form of a private or public offering of debt or equity securities or
additional bank financing. No assurances can be given that the necessary
financing will be obtainable on terms satisfactory to the Company. The failure
to raise the funds necessary to finance its future cash requirements could
adversely affect the Company's ability to pursue its strategy and could
adversely affect its results of operations for future periods.
 
YEAR 2000
 
     The Company is evaluating the Year 2000 issues and the impact upon
information systems and computer technologies. While certain applications in
system software critical to processing financial and operational information are
Year 2000 compliant, the Company expects to incur some costs in testing and
implementing
                                       21
<PAGE>   26
 
updates to such software. The Company is also evaluating the impact of the Year
2000 on other computer technologies and software. All costs to evaluate and make
modifications will be expensed as incurred and are not expected to have a
significant impact on the Company's ongoing results of operations.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
   
     Statement of Financial Accounting Standard ("SFAS") No. 130 "Reporting
Comprehensive Income" became effective for the Company during the first quarter
of 1998 and its adoption did not have a material impact on the Company's
financial reporting practices. SFAS No. 131 "Disclosures about Segments of an
Enterprise and Related Information" becomes effective for the Company for the
year ended December 31, 1998. The Company is still evaluating the effects of
adopting this statement, but does not expect its adoption to have a material
effect on the Company's consolidated financial statements.
    
 
   
     Statement of Position ("SOP") No. 98-5 "Reporting on the Costs of Start-Up
Activities" becomes effective for the Company for the year ended December 31,
1999. SOP No. 98-5 requires that start-up costs be expensed as incurred and that
upon adoption, all deferred start-up costs be expensed as a cumulative effect of
a change in accounting principle. The Company does not anticipate that the
adoption of SOP No. 98-5 will have a material effect on the Company's financial
position or ongoing results of operations.

                                    BUSINESS
 
   
     The Company develops, acquires and operates practice-based ambulatory
surgery centers, in partnership with physician practice groups, throughout the
United States. As of May 1, 1998, the Company owned a majority interest in 44
surgery centers and a minority interest in one center in 20 states and the
District of Columbia. The Company also had six centers under development, had
executed letters of intent to develop or acquire six additional centers and had
two centers awaiting CON approval. The Company believes that it is a leader in
the ownership and operation of practice-based ambulatory surgery centers.
    
 
     The Company's centers are licensed for outpatient surgery, are generally
equipped and staffed for a single medical specialty and are usually located in
or adjacent to the offices of a physician group practice. The Company has
targeted ownership in centers that perform gastrointestinal endoscopy,
ophthalmology, urology, orthopaedics or otolaryngology procedures. Surgical
procedures associated with these specialties include many types of high volume,
lower-risk procedures that are appropriate for the practice-based setting. The
Company believes its single specialty centers have significantly lower capital
and operating costs than hospital and freestanding ambulatory surgery center
alternatives that are designed to accommodate a broader array of surgical
specialties and procedures. In addition, the practice-based surgery center
provides a more convenient setting for the patient and for the physician
performing the procedure.
 
   
     The Company is utilizing its surgery centers in selected markets as a base
to develop start-up specialty physician networks that are designed to serve
large numbers of covered lives and thus strengthen the Company's position in
contracting with managed care organizations. As of May 1, 1998, the Company had
established five start-up specialty physician networks, located in Alabama,
Florida, Ohio, Tennessee and Texas.
    
 
INDUSTRY OVERVIEW
 
     In recent years, government programs, private insurance companies, managed
care organizations and self-insured employers have implemented various
cost-containment measures to limit the growth of healthcare expenditures. These
cost-containment measures, together with technological advances, have resulted
in a significant shift in the delivery of healthcare services away from
traditional inpatient hospitals to more cost-effective alternate sites,
including ambulatory surgery centers.
 
     According to SMG Marketing Group Inc.'s Freestanding Outpatient Surgery
Center Directory (June 1997), an industry publication, outpatient surgical
procedures represented approximately 69% of all surgical procedures performed in
the United States in 1996 and the number of outpatient surgery cases increased
54% from 3.1 million in 1993 to 4.8 million in 1996. As of December 31, 1996,
there were 2,425 freestanding ambulatory surgery centers in the United States,
of which 171 were owned by hospitals and 607 were owned by corporate entities.
The remaining 1,647 centers were independently owned, primarily by physicians.
 
     The Company believes that the following factors have contributed to the
growth of ambulatory surgery:
 
          Cost-Effective Alternative.  Ambulatory surgery is generally less
     expensive than hospital inpatient surgery. In addition, the Company
     believes that surgery performed at a practice-based ambulatory surgery
     center is generally less expensive than hospital-based ambulatory surgery
     for a number of reasons, including lower facility development costs, more
     efficient staffing and space utilization and a specialized operating
     environment focused on cost containment. Interest in ambulatory surgery
     centers has grown as managed care organizations have continued to seek a
     cost-effective alternative to inpatient services.
 
          Physician and Patient Preference.  The Company believes that many
     physicians prefer practice-based ambulatory surgery centers. The Company
     believes that such centers enhance physicians' productivity by providing
     them with greater scheduling flexibility, more consistent nurse staffing
     and faster turnaround time between cases, allowing them to perform more
     surgeries in a defined period of time. In contrast, hospitals and
     freestanding multi-specialty ambulatory surgery centers generally serve a
     broader group of physicians, including those involved with emergency
     procedures, resulting in postponed or delayed surgeries. Additionally, many
     physicians choose to perform surgery in a practice-based
                                       23
<PAGE>   28
 
     ambulatory surgery center because their patients prefer the simplified
     admissions and discharge procedures and the less institutional atmosphere.
 
          New Technology.  New technology and advances in anesthesia, which have
     been increasingly accepted by physicians, have significantly expanded the
     types of surgical procedures that are being performed in ambulatory surgery
     centers. Lasers, enhanced endoscopic techniques and fiber optics have
     reduced the trauma and recovery time associated with many surgical
     procedures. Improved anesthesia has shortened recovery time by minimizing
     post-operative side effects such as nausea and drowsiness, thereby
     avoiding, in some cases, overnight hospitalization.
 
STRATEGY
 
     The Company believes it is a leader in the development, acquisition and
operation of practice-based ambulatory surgery centers. The key components of
the Company's strategy are:
 
          Develop and Acquire Practice-Based Ambulatory Surgery Centers.  The
     Company expects to grow through a combination of acquisitions and
     development of single specialty centers throughout the United States.
     Although the Company historically has grown primarily by acquisition of
     existing centers, it anticipates that its future growth will come
     increasingly from development of new practice-based ambulatory surgery
     centers.
 
          Achieve Growth in Surgery Center Revenues and Profitability.  The
     Company enhances physician productivity and promotes increased same-center
     revenues and profitability by creating operating efficiencies, including
     improved scheduling, group purchasing programs and the clinical
     efficiencies associated with operating a single specialty surgery center.
     In addition, the Company's operations are designed to attract additional
     managed care contracts by emphasizing convenience, a single specialty
     focus, lower cost procedures and the ability to contract for large numbers
     of covered lives.
 
          Develop Specialty Networks.  Utilizing single specialty ambulatory
     surgery centers to provide a cost advantage, the Company's strategy has
     evolved to include the development and ownership of specialty physician
     networks which offer specialty physician services, as well as outpatient
     surgery procedures with wide geographic coverage to managed care payers.
     These specialty networks will be developed in selected markets to provide
     broad geographic patient access points in the market through the network
     participation of high quality and strategically located practices.
 
   
          As part of this strategy, the Company has established and is the
     majority owner of five start-up specialty physician networks. By
     establishing these networks, the Company believes it will be able to obtain
     additional contracts with managed care payers and increase the
     profitability of its surgery centers and associated physician practices.
    
 
ACQUISITION AND DEVELOPMENT OF SURGERY CENTERS
 
     The Company's practice-based ambulatory surgery centers are licensed
outpatient surgery centers generally equipped and staffed for a single medical
specialty and generally are located in or adjacent to a physician group
practice. The Company has targeted ownership in centers that perform
gastrointestinal endoscopy, ophthalmology, urology, orthopaedics or
otolaryngology procedures. These specialties perform many high volume,
lower-risk procedures that are appropriate for the practice-based setting. The
focus at each center on only the procedures in a single specialty results in
these centers generally having significantly lower capital and operating costs
than the costs of hospital and freestanding ambulatory surgery center
alternatives that are designed to provide more intensive services in a broader
array of surgical specialties. In addition, the practice-based surgery center,
which is located in or adjacent to the group practice, provides a more
convenient setting for the patient and for the physician performing the
procedure. Improvements in technology are also enabling additional types of
procedures to be performed in the practice-based setting.
 
     The Company's development staff identifies existing centers that are
potential acquisition candidates and identifies physician practices that are
potential partners for new center development in the medical specialties
 
                                       24
<PAGE>   29
 
which the Company has targeted for development. These candidates are evaluated
against the Company's project criteria which include several factors such as the
number of procedures currently being performed by the practice, competition from
and the fees being charged by other surgical providers, relative competitive
market position of the physician practice under consideration, and state CON
requirements for development of a new center.
 
     In presenting the advantages to physicians of developing a new
practice-based ambulatory surgery center in partnership with the Company, the
Company's development staff emphasizes the proximity of a practice-based surgery
center to a physician's office, the simplified administrative procedures, the
ability to schedule consecutive cases without preemption by inpatient or
emergency procedures, the rapid turnaround time between cases, the high
technical competency of the center's clinical staff that performs only a limited
number of specialized procedures and the availability of state-of-the-art
surgical equipment. The Company also focuses on its expertise in developing and
operating centers. In addition, as part of the Company's role as the general
partner or manager of the surgery center partnerships and limited liability
companies, the Company markets the centers to third party payers.
 
     In a development project, the Company, among other things, provides the
following services:
 
     - Financial feasibility pro forma analysis;
     - Assistance in state CON approval process;
     - Site selection;
     - Assistance in space analysis and schematic floor plan design;
     - Analysis of local, state and federal building codes;
     - Negotiation of equipment financing with lenders;
     - Equipment budgeting, specification, bidding and purchasing;
     - Construction financing;
     - Architectural oversight;
     - Contractor bidding;
     - Construction management; and
     - Assistance with licensing, Medicare certification and third party payer
contracts.
 
     The Company's ownership interests in practice-based ambulatory surgery
centers generally are structured through limited or general partnerships or
limited liability companies. The Company generally owns 51% to 70% of the
partnerships or limited liability companies and acts as the general partner in
each limited partnership. In development transactions, capital contributed by
the physicians and the Company plus bank financing provides the partnership or
limited liability company with the funds necessary to construct and equip a new
surgery center and to provide initial working capital.
 
     As part of each development and acquisition transaction, the Company enters
into a partnership agreement or, in the case of a limited liability company, an
operating agreement with its physician group partner. Under these agreements,
the Company receives a percentage of the net income and cash distributions of
the entity equal to its percentage interest in the entity and has the right to
the same percentage of the proceeds of a sale or liquidation of the entity. As
sole general partner, the Company is generally liable for the debts of the
partnership.
 
     These agreements generally provide that the Company will oversee the
business and administrative operations of the surgery center, and that the
physician group partner will provide the center with a medical director, and
with certain specified services such as billing and collections, transcription,
and accounts payable processing. In connection with the Company's management of
the business operations at each center, the Company historically received a
management fee paid by the partnership or limited liability company. The
partnership or limited liability company also paid a physician group partner a
medical director fee and a fee for providing certain administrative services to
the center. Because the management fee usually approximates the value of
services provided to the center by the physician practice, on an ongoing basis,
the Company has structured its agreements so that the Company generally no
longer provides for any of such fees. Now, the respective parties are required
to provide the services pursuant to the terms of the partnership or operating
 
                                       25
<PAGE>   30
 
agreement. For start-up centers that are being developed, the partnership or
limited liability company generally pays a fee to the Company for management of
the planning, construction and opening of the center.
 
     In addition, these agreements typically provide that the partnership or
limited liability company will lease certain non-physician personnel from the
physician practice, who will provide services at the center. The cost of the
salary and benefits of these personnel are reimbursed to the practice by the
partnership or limited liability company. Certain significant aspects of the
partnership's or limited liability company's governance are overseen by an
operating board, which is comprised of equal representation by the Company and
the physician partners.
 
     The partnership and operating agreements provide that if certain regulatory
changes take place the Company will be obligated to purchase some or all of the
minority interests of the physicians affiliated with the Company in the
partnerships or limited liability companies which own and operate the Company's
surgery centers. The regulatory changes that could trigger such an obligation
include changes that: (i) make the referral of Medicare and other patients to
the Company's surgery centers by physicians affiliated with the Company illegal;
(ii) create the substantial likelihood that cash distributions from the
partnership or limited liability company to the physicians associated therewith
will be illegal; or (iii) cause the ownership by the physicians of interests in
the partnerships or limited liability companies to be illegal. There can be no
assurance that the Company's existing capital resources would be sufficient for
it to meet the obligation, if it arises, to purchase minority interests held by
physicians in the partnerships or limited liability companies which own and
operate the Company's surgery centers. The determination of whether a triggering
event has occurred is made by the concurrence of counsel for the Company and the
physician partners or, in the absence of such concurrence, by independent
counsel having an expertise in healthcare law and who is chosen by both parties.
Such determination is therefore not within the control of the Company. While the
Company has structured the purchase obligations to be as favorable as possible
to the Company, the triggering of these obligations could have a material
adverse effect on the financial condition and results of operations of the
Company. See "-- Government Regulation."

     The Company's partnerships and limited liability companies lease certain of
the real property in which its centers operate and the equipment used in certain
of its centers, either from the physician partners or from unaffiliated parties.
 
SURGERY CENTER OPERATIONS
 
   
     The Company generally designs, builds, staffs and equips each of its
facilities to meet the specific needs of a single specialty physician practice
group. The Company's typical ambulatory surgery center averages 3,000 square
feet and is located adjacent to or in the immediate vicinity of the specialty
physicians' offices. Each center developed by the Company typically has two to
three operating or procedure rooms with areas for reception, preparation,
recovery and administration. As of May 1, 1998, 34 of the Company's centers in
operation performed gastrointestinal endoscopy procedures, nine centers
performed ophthalmology procedures, one center performed orthopaedic procedures
and one center performed ophthalmology, urology, general surgery and
otolaryngology procedures. The procedures performed at the Company's centers
generally do not require an extended recovery period following the procedures.
The Company's centers are typically staffed with three to five clinical
professionals and administrative personnel, some of whom may be shared with the
physician practice group. The clinical staff includes nurses and surgical
technicians.
    
 
     The types of procedures performed at each center depend on the specialty of
the practicing physicians. The typical procedures performed or to be performed
most commonly at the Company's centers in operation or under development within
each specialty are:
 
     - Gastroenterology -- colonoscopy and endoscopy procedures
     - Ophthalmology -- cataracts and retinal laser surgery
     - Orthopaedics -- knee arthroscopy and carpal tunnel repair
     - Urology -- cystoscopy and biopsy
     - Otolaryngology -- myringotomy and tonsillectomy
 
     The Company markets its surgery centers and networks directly to
third-party payers, including HMOs, preferred provider organizations ("PPOs"),
other managed care organizations and employers. Payer-group marketing activities
conducted by the Company's management and center administrators emphasize the
high quality of care, cost advantages and convenience of the Company's surgery
centers and are focused on making each center an approved provider under local
managed care plans. In addition, the Company is pursuing relationships with
selected physician groups in its markets in order to market a comprehensive
specialty physician network that includes its surgery centers to managed care
payers.
 
JCAHO ACCREDITATION
 
     Twenty of the Company's surgery centers are currently accredited by the
Joint Commission for the Accreditation of Healthcare Organizations ("JCAHO") and
17 additional surgery centers are scheduled for accreditation surveys during
1998. Of the accredited centers, all have received three-year certification with
15 of the 20 receiving commendation. The Company believes that JCAHO
accreditation is the quality benchmark for managed care organizations. Many
managed care organizations will not contract with a facility until it is JCAHO
accredited. The Company believes that its historical performance in the
accreditation process reflects the Company's commitment to providing high
quality care in its surgery centers.
 
SPECIALTY PHYSICIAN NETWORKS
 
     Managed care organizations with significant numbers of covered lives are
seeking to direct large numbers of patients to high-quality, low-cost providers
and provider groups. The Company believes that specialty physician networks that
include its practice-based surgery centers are attractive to managed care
organizations because of the geographic coverage of the network, the lower costs
associated with treatment, the availability of the complete delivery system for
a specific specialty and high levels of patient satisfaction. As a result, the
Company believes the development of such networks will position it to capture an
increased volume of managed care contracts, including capitated contracts, and
will increase the market share and profitability of the Company's surgery
centers and physician practices.
                                       28
<PAGE>   33
 
     The Company does not expect that the specialty physician networks
themselves will be a significant source of income for the Company. These
networks were and will be formed primarily as a contracting vehicle to generate
revenues for the Company's practice-based surgery centers and physician
practices.
 
   
     As of March 31, 1998, the Company had established and was the majority
owner and operator of five start-up specialty physician networks consisting of a
gastroenterology network in Miami and four ophthalmology/eye care networks
located in Knoxville, Tennessee; Montgomery, Alabama; Cleveland, Ohio; and
Abilene, Texas. These networks had not generated any revenues as of March 31,
1998. Each specialty physician network is formed either as a limited partnership
or limited liability company in which the Company owns a majority interest.
Individual physicians practicing in the medical specialty on which the network
focuses own the minority interests in the network. These minority physician
owners, who may or may not be affiliated with a Company surgery center or
physician practice, provide the medical services to the patient population
covered by the contracts the network enters into with managed care payers.
Following the establishment of a network, the Company provides management
services and marketing services to the network in an effort to secure patient
service contracts with managed care payers. Fees paid by these networks to the
Company are nominal and generally are intended to cover only the Company's cost
in providing such services.
    
 
   
     In addition, as part of its network development strategy, in January 1996
and January 1997 the Company acquired a majority interest in the assets of two
physician practices in Miami, Florida. As a result of the Company's experience
in developing specialty physician networks, the Company does not believe that
ownership of physician practices is required in order to establish a specialty
physician network. In May 1998, the Board of Directors approved a plan for the
Company to dispose of its physician practice interests as part of an overall
strategy to exit the practice management business and focus solely on the
development, acquisition and operation of ambulatory surgery centers and
specialty networks.
    
 
REVENUES
 
     The Company's principal source of revenues is a facility fee charged for
surgical procedures performed in its surgery centers. This fee varies depending
on the procedure, 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 patient's surgeon,
anesthesiologist or other attending physicians, which are billed directly to
third-party payers by such physicians. The Company's other significant source of
revenues is the fee for physician services performed by the two physician group
practices in which the Company owns a majority interest.
 
     Practice-based ambulatory surgery centers and physician practices such as
those in which the Company owns a majority interest depend upon third-party
reimbursement programs, including governmental and private insurance programs,
to pay for services rendered to patients. The Company derived approximately 37%
of its net revenues from governmental healthcare programs, including Medicare
and Medicaid, in 1997. The Medicare program currently pays ambulatory surgery
centers and physicians in accordance with fee schedules which are prospectively
determined. On or before January 1, 1999, outpatient surgery services will be
reimbursed by Medicare under a revised prospective payment system, utilizing
approximately 100 ambulatory patient classifications, rather than the eight
codes currently utilized. There can be no assurance that the Company's revenues
will not be adversely affected under this revised payment system. There may be
continuing legislative and regulatory initiatives to limit the rate of increase
in expenditures under the Medicare and Medicaid programs in an effort to curtail
or reduce the federal budget deficit. These limitations, if enacted, may
negatively impact the Company's revenues and operations.
 
     In addition to payment from governmental programs, ambulatory surgery
centers derive a significant portion of their net revenues from private
healthcare reimbursement plans. These plans include both standard indemnity
insurance programs, as well as managed care structures such as PPOs, HMOs and
other similar structures. The strengthening of managed care systems nationally
has resulted in substantial competition among providers of services, including
providers of surgery center services with greater financial resources and market
penetration than the Company, to contract with these systems. The Company
believes that all payers, both governmental and private, will continue their
efforts over the next several years to reduce healthcare costs
 
                                       29
<PAGE>   34
 
and that their efforts generally will result in a less stable market for
healthcare services. While no assurances can be given concerning the ultimate
success of the Company's efforts to contract with healthcare payers, the Company
believes that its position as a low-cost alternative for certain surgical
procedures should enable the Company's centers to compete effectively in the
evolving healthcare marketplace.
 
     Approximately 11% of the Company's revenues for 1997 were generated by
capitated payment contracts with HMOs. These revenues generally were
attributable to contracts held by physician practices and a surgery center in
which the Company holds a majority interest. These contracts require the
practices to provide specialty physician and certain outpatient surgery services
for the HMO members on an exclusive basis. These contracts do not require the
practices to provide or to be at risk for hospital or other ancillary services
such as laboratory or imaging services. The services required by these contracts
are provided almost solely by surgery centers and the physician practices in
which the Company owns a majority interest. Because the Company is only at risk
for the cost of providing relatively limited healthcare services to these HMO
members, the Company's risk of overutilization by HMO members is limited to the
cost of the physician's time and the supply, drug and nursing staff expense
required for outpatient surgery.
 
COMPETITION
 
     The Company encounters competition in two separate areas: competition with
other companies for its physician partnership relationships and competition with
other providers for patients and for contracting with managed care payers in
each of its markets.
 
     Competition for Partnership Relationships.  The Company believes that it
does not have a direct competitor in the development of practice-based
ambulatory surgery centers across the specialties of gastroenterology,
ophthalmology, otolaryngology, urology, and orthopaedic surgery. There are,
however, several large, publicly-held companies, or divisions or subsidiaries of
large publicly-held companies, that develop freestanding multi-specialty surgery
centers, and these companies may compete with the Company in the development of
centers.
 
     Many physician groups develop surgery centers without a corporate partner.
It is generally difficult, however, in the rapidly evolving healthcare industry,
for a single practice to create effectively the efficient operations and
marketing programs necessary to compete with other provider networks and
companies. Because of this, as well as the financial investment necessary to
develop surgery centers, physician groups are attracted to corporate partners,
such as the Company. Other factors that may influence the physicians' decisions
concerning the choice of a corporate partner are the potential corporate
partner's experience, reputation and access to capital.
 
     There are several companies, many in niche markets, that acquire existing
practice-based ambulatory surgery centers and specialty physician practices.
Many of these competitors have greater resources than the Company. Most of the
Company's competitors acquire centers through the acquisition of the related
physician practice. The principal competitive factors that affect the ability of
the Company and its competitors to acquire surgery centers are price, experience
and reputation, access to capital and willingness to acquire a surgery center
without acquiring the physician practice.
 
     While there are a few national networking companies that specialize in the
establishment and operation of single specialty networks similar to the
Company's networks, most networks are either multi-specialty or primary care
based. The competitive factors the Company primarily experiences in the
development of specialty networks include the ability to attract physician
practice groups to the network and to achieve market penetration and geographic
coverage.
 
     Competition for Patients and Managed Care Contracts.  The Company believes
that its surgery centers can provide lower-cost, high quality surgery in a more
comfortable environment for the patient in comparison to hospitals and to
freestanding surgery centers with which the Company competes for managed care
contracts. In addition, the existence of the Company's specialty physician
networks are designed to provide the geographic access within local markets that
managed care companies desire. Competition for managed care
 
                                       30
<PAGE>   35
 
contracts with other providers is focused on pricing of services, quality of
services, and affiliation with key physician groups in a particular market.
 
GOVERNMENT REGULATION
 
     The healthcare industry is subject to extensive regulation by a number of
governmental entities at the federal, state and local level. Regulatory
activities affect the business activities of the Company by controlling the
Company's growth, requiring licensure and certification for its facilities,
regulating the use of the Company's properties, and controlling reimbursement to
the Company for the services it provides.
 
     CONs and State Licensing.  CON regulations control the development of
ambulatory surgery centers in certain states. CONs generally provide that prior
to the expansion of existing centers, the construction of new centers, the
acquisition of major items of equipment or the introduction of certain new
services, approval must be obtained from the designated state health planning
agency. State CON statutes generally provide that, prior to the construction of
new facilities or the introduction of new services, a designated state health
planning agency must determine that a need exists for those facilities or
services. The Company's development of ambulatory surgery centers generally
focuses on states that do not require CONs. However, acquisitions of existing
surgery centers, even in states that require CONs for new centers, generally do
not require CON regulatory approval.
 
     State licensing of ambulatory surgery centers is generally a prerequisite
to the operation of each center and to participation in federally funded
programs, such as Medicare and Medicaid. Once a center becomes licensed and
operational, it must continue to comply with federal, state and local licensing
and certification requirements in addition to local building and life safety
codes. In addition, every state imposes licensing requirements on individual
physicians, and facilities and services operated and owned by physicians.
Physician practices are also subject to federal, state and local laws dealing
with issues such as occupational safety, employment, medical leave, insurance
regulations, civil rights and discrimination, and medical waste and other
environmental issues.
 
     Corporate Practice of Medicine.  The Company is not required to obtain a
license to practice medicine in any jurisdiction in which it owns and operates
an ambulatory surgery center, because the surgery centers are not engaged in the
practice of medicine. The physicians who perform procedures at the surgery
centers are individually licensed to practice medicine. The group practices,
with the exception of the two physician practices majority owned by the Company,
are not affiliated with the Company other than through the physicians' ownership
in the partnerships and limited liability companies that own the surgery
centers. The Company owns a majority interest in two group practices in Florida,
a state which permits physicians to practice medicine through an entity that is
not wholly owned by physicians. All third party payer contracts for physician
services are in the name of the group practice entities in which the Company
owns a majority interest. The physicians associated with these group practices
provide medical services to the patients of the practice entities and are
compensated for these services pursuant to either an employment contract or an
independent contractor arrangement with the practice entity. The Company's
operations do not require the Company to otherwise obtain any license to
practice medicine in any other jurisdiction. A recent ruling by the Florida
Board of Medicine that an agreement between a physician practice and a practice
management company constituted impermissible fee-splitting, if upheld on
judicial appeal, would cause the Company to restructure its relationship with
one of the two group practices. The Company does not believe that any such
restructuring would have a material adverse effect on the Company.
 
     Insurance and Antitrust Laws.  Laws in all states regulate the business of
insurance and the operation of HMOs. Many states also regulate the establishment
and operation of networks of healthcare providers. The Company believes that its
operations are in compliance with these laws in the states in which it currently
does business. The NAIC recently endorsed a policy proposing the state
regulation of risk assumption by healthcare providers. The policy proposes
prohibiting providers from entering into capitated payment or other risk sharing
contracts except through HMOs or insurance companies. Several states have
adopted regulations implementing the NAIC policy in some form. In states where
such regulations have been adopted, healthcare providers
 
                                       31
<PAGE>   36
 
will be precluded from entering into capitated contracts directly with employers
and benefit plans other than HMOs and insurance companies.
 
     The Company and its affiliated groups may in the future enter into
additional contracts with managed care organizations, such as HMOs, whereby the
Company and its affiliated groups would assume risk in connection with providing
healthcare services under capitation arrangements. If the Company or its
affiliated groups are considered to be in the business of insurance as a result
of entering into such risk sharing arrangements, they could become subject to a
variety of regulatory and licensing requirements applicable to insurance
companies or HMOs, which could have a material adverse effect upon the Company's
ability to enter into such contracts.
 
     With respect to managed care contracts that do not involve capitated
payments or some other form of financial risk sharing, federal and state
antitrust laws restrict the ability of healthcare provider networks such as the
Company's specialty physician networks to negotiate payments on a collective
basis.
 
     Reimbursement.  The Company depends upon third-party programs, including
governmental and private health insurance programs, to reimburse it for services
rendered to patients in its ambulatory surgery centers. In order to receive
Medicare reimbursement, each ambulatory surgery center must meet the applicable
conditions of participation set forth by the Department of Health and Human
Services ("DHHS") relating to the type of facility, its equipment, personnel and
standard of medical care, as well as compliance with state and local laws and
regulations, all of which are subject to change from time to time. Ambulatory
surgery centers undergo periodic on-site Medicare certification surveys. Each of
the Company's existing centers is certified as a Medicare provider. Although the
Company intends for its centers to participate in Medicare and other government
reimbursement programs, there can be no assurance that these centers will
continue to qualify for participation.
 
     Medicare-Medicaid Illegal Remuneration Provisions.  The anti-kickback
statute makes unlawful knowingly and willfully soliciting, receiving, offering
or paying any remuneration (including any kickback, bribe, or rebate) directly
or indirectly to induce or in return for referring an individual to a person for
the furnishing or arranging for the furnishing of any item or service for which
payment may be made in whole or in part under Medicare or Medicaid. Violation is
a felony punishable by a fine of up to $25,000 or imprisonment for up to five
years, or both. The Medicare and Medicaid Patient Program Protection Act of 1987
(the "1987 Act") provides administrative penalties for healthcare practices
which encourage overutilization or illegal remuneration when the costs of
services are reimbursed under the Medicare program. Loss of Medicare
certification and severe financial penalties are included among the 1987 Act's
sanctions. The 1987 Act, which adds to the criminal penalties under preexisting
law, also directs the Inspector General of the DHHS to investigate practices
which may constitute overutilization, including investments by healthcare
providers in medical diagnostic facilities, and to promulgate regulations
establishing exemptions or "safe harbors" for investments by medical service
providers in legitimate business ventures that will be deemed not to violate the
law even though those providers may also refer patients to such a venture.
Regulations identifying safe harbors were published in final form in July 1991
(the "Regulations").
 
     The Regulations set forth two specific exemptions or "safe harbors" related
to "investment interests": the first concerning investment interests in large
publicly traded companies ($50,000,000 in net tangible assets) and the second
for investments in smaller entities. The partnerships and limited liability
companies that own the Company's centers do not meet all of the criteria of
either existing "investment interests" safe harbor as announced in the
Regulations.
 
     While several federal court decisions have aggressively applied the
restrictions of the anti-kickback statute, they provide little guidance as to
the application of the anti-kickback statute to the Company's partnerships and
limited liability companies. The Company believes that the physician partner's
ownership
 
                                       32
<PAGE>   37
 
interest in the Company's centers is in compliance with the current requirements
of applicable federal and state law because among other factors:
 
          i. the partnerships and limited liability companies exist to effect
     legitimate business purposes, including the ownership, operation and
     continued improvement of quality, cost effective and efficient services to
     their patients;
 
          ii. the partnerships and limited liability companies function as an
     extension of the group practices of physicians who are affiliated with the
     surgery centers and the surgical procedures are performed personally by
     these physicians without referring the patients outside of their practice;
 
          iii. the physician partners have a substantial investment at risk in
     the partnership or limited liability company;
 
          iv. terms of the investment do not take into account volume of the
     physician partner's past or anticipated future services provided to
     patients of the centers;
 
          v. the physician partners are not required or encouraged as a
     condition of the investment to treat Medicare or Medicaid patients at the
     centers or to influence others to refer such patients to the centers for
     treatment;
 
          vi. neither the partnership, limited liability company, the Company
     subsidiary, nor any of their affiliates will loan any funds or guarantee
     any debt on behalf of the physician partners; and
 
          vii. distributions by the partnerships and limited liability companies
     are allocated uniformly in proportion to ownership interests.
 
     The Regulations also set forth a safe harbor for personal services and
management contracts. Certain of the Company's partnerships and limited
liability companies have entered into ancillary services agreements with their
physician partners' group practice pursuant to which the practice provides the
center with billing and collections, transcription, payables processing and
payroll services. The consideration payable by the partnership or limited
liability company for these services is based on the volume of services provided
by the practice which is measured by the partnership or limited liability
company's revenues. Although these relationships do not meet all of the criteria
of the personal services and management contracts safe harbor, the Company
believes that the ancillary services agreements are in compliance with the
current requirements of applicable federal and state law because, among other
factors, the fees payable to the physician practice approximate the practice's
cost of providing the services thereunder.
 
     Notwithstanding the Company's belief that the relationship of physician
partners to the Company's surgery centers should not constitute illegal
remuneration under the anti-kickback statute, no assurances can be given that a
federal or state agency charged with enforcement of the anti-kickback statute
and similar laws might not assert a contrary position or that new federal or
state laws might not be enacted that would cause the physician partners'
relationships with the Company's centers to become illegal, or result in the
imposition of penalties on the Company or certain of its facilities. Even the
assertion of a violation could have a material adverse effect upon the Company.
 
     Prohibition on Physician Ownership of Healthcare Facilities.  The so-called
"Stark II" provisions of the Omnibus Budget Reconciliation Act of 1993 ("OBRA
93") amend the federal Medicare statute to prohibit the making by a physician of
referrals for "designated health services" to an entity in which the physician
has an investment interest or other financial relationship, subject to certain
exceptions. A referral under Stark II that does not fall within an exception is
strictly prohibited. This prohibition took effect on January 1, 1995. Sanctions
for violating Stark II can include civil monetary penalties and exclusion from
Medicare and Medicaid.
 
     Ambulatory surgery is not identified as a "designated health service", and
the Company, therefore, does not believe that ambulatory surgery is otherwise
subject to the restrictions set forth in Stark II. Proposed regulations pursuant
to Stark II that were published on January 9, 1998 specifically provide that
services provided in an ambulatory surgery center and reimbursed under the
composite payment rate are not
 
                                       33
<PAGE>   38
 
designated health services. However, unfavorable final Stark II regulations or
subsequent adverse court interpretations concerning similar provisions found in
recently enacted state statutes could prohibit reimbursement for treatment
provided by the physicians affiliated with the Company's centers to their
patients. The Company cannot predict whether other regulatory or statutory
provisions will be enacted by federal or state authorities which would prohibit
or otherwise regulate relationships which the Company has established or may
establish with other healthcare providers or the possibility of material adverse
effects on its business or revenues arising from such future actions. The
Company believes, however, that it will be able to adjust its operations so as
to be in compliance with any regulatory or statutory provision, as may be
applicable.
 
     The Company is subject to state and federal laws that govern the submission
of claims for reimbursement. These laws generally prohibit an individual or
entity from knowingly and willfully presenting a claim (or causing a claim to be
presented) for payment from Medicare, Medicaid or other third party payers that
is false or fraudulent. The standard for "knowing and willful" often includes
conduct that amounts to a reckless disregard for whether accurate information is
presented by claims processors. Penalties under these statutes include
substantial civil and criminal fines, exclusion from the Medicare program, and
imprisonment. One of the most prominent of these laws is the federal False
Claims Act, which may be enforced by the federal government directly, or by a
qui tam plaintiff on the government's behalf. Under the False Claims Act, both
the government and the private plaintiff, if successful, are permitted to
recover substantial monetary penalties, as well as an amount equal to three
times actual damages. In recent cases, some qui tam plaintiffs have taken the
position that violations of the anti-kickback statute and Stark II should also
be prosecuted as violations of the federal False Claims Act. The Company
believes that it has procedures in place to ensure the accurate completion of
claims forms and requests for payment. However, the laws and regulations
defining the proper parameters of proper Medicare or Medicaid billing are
frequently unclear and have not been subjected to extensive judicial or agency
interpretation. Billing errors can occur despite the Company's best efforts to
prevent or correct them, and no assurances can be given that the government will
regard such errors as inadvertent and not in violation of the False Claims Act
or related statutes.
 
     Under its agreements with its physician partners, the Company is obligated
to purchase the interests of the physicians at the greater of the physicians'
capital account or a multiple of earnings in the event that their continued
ownership of interests in the partnerships and limited liability companies
becomes prohibited by the statutes or regulations described above. The
determination of such a prohibition is required to be made by counsel of the
Company in concurrence with counsel of the physician partners, or if they cannot
concur, by a nationally recognized law firm with an expertise in healthcare law
jointly selected by the Company and the physician partners. The interest
required to be purchased by the Company will not exceed the minimum interest
required as a result of the change in the statute or regulation causing such
prohibition.
 
PROPERTIES
 
   
     The Company's principal executive offices are located in Nashville,
Tennessee and contain an aggregate of approximately 15,000 square feet of office
space, which the Company subleases from AHC pursuant to an agreement that
expires in December 1999. The Company's partnerships and limited liability
companies generally lease space for their surgery centers. Forty-three of the
centers and the physician practices in operation at May 1, 1998 lease space
ranging from 1,200 to 13,500 square feet with remaining lease terms ranging from
two to 18 years. Two centers in operation at May 1, 1998 are located in
buildings owned indirectly by the Company.
    
 
EMPLOYEES
 
     As of December 31, 1997, the Company and its affiliated entities employed
approximately 250 persons, 200 of whom were full-time employees and 50 of whom
were part-time employees. Of the above, 64 were employed at the Company's
headquarters in Nashville, Tennessee. In addition, approximately 190 employees
are leased on a full-time basis and 110 are leased on a part-time basis from the
associated physician practices. None of these employees are represented by a
union. The Company believes its employee relations to be good.

COMPENSATION OF DIRECTORS
 
     Members of the Board of Directors, other than those who are employees of
the Company, receive an annual fee of $10,000, adjusted annually to reflect
changes in the Consumer Price Index, U.S. All City Average Report, of the U.S.
Bureau of Labor Statistics (the "CPI") for their services as directors and as
members of any committees of the Board of Directors on which they serve. In
addition, each non-employee director is reimbursed for out-of-pocket expenses
incurred in attending Board of Directors' meetings and committee meetings. Also,
Outside Directors (as defined below) are eligible to receive annual restricted
stock awards ("Outside Director Restricted Stock") pursuant to the 1997 Plan. An
"Outside Director" is a member of the Board of Directors who is not an officer
or employee of the Company, its subsidiaries or affiliates. A director serving
as medical director of the Company but not as an employee of the Company will be
treated as an Outside Director for purposes of the 1997 Plan. On the date of
each annual meeting of shareholders of the Company, each Outside Director who is
elected or reelected to the Board of Directors or who otherwise continues as a
director shall automatically receive on the date of the annual meeting of
shareholders a grant of that number of shares of restricted Class A Common Stock
having an aggregate fair market value on such date equal to $10,000, adjusted
annually for changes in the CPI. Members of the Board of Directors who are
employees of the Company will not receive any additional compensation for their
services as directors or as members of committees.
 
   
     Each grant of Outside Director Restricted Stock shall vest in increments of
one-third of the shares of Class A Common Stock subject to such grant, with the
first one-third increment vesting on the date of grant, the second one-third
increment vesting on the first anniversary of the date of grant and the final
one-third increment vesting on the second anniversary of the date of grant, if
the grantee is still a member of the Board of Directors on each of such dates.
Until the earlier of (i) five years from the date of grant and (ii) the date on
which the Outside Director ceases to serve as a director of the Company, no
Outside Director Restricted Stock may be sold, transferred, pledged, assigned,
or otherwise alienated or hypothecated, except by will or by the laws of descent
and distribution. Upon termination of an Outside Director's service as a member
of the Board of Directors for any reason other than death, disability or
retirement, all shares of Outside Director Restricted Stock not vested at such
time will be forfeited. Upon termination of an Outside Director's service as a
member of the Board of Directors due to death, disability or retirement, all
shares of Outside Director Restricted Stock will immediately vest. Pursuant to
Section 9 of the 1997 Plan, during December 1997 and May 1998, each Outside
Director received a grant of Outside Director Restricted Stock having an
aggregate fair market value on such date equal in value to $10,000 on each of
such dates.

EMPLOYMENT AGREEMENTS
 
     The Company has employment agreements with each of Mr. McDonald, Ms. Gulmi,
Mr. Harrell, Mr. Lunn and Mr. Manning (the "Employment Agreements"). The
Employment Agreements have an initial one-year term, but contain a provision
that automatically extends the term for an additional one year on the first and
each successive anniversary date of the Employment Agreements until such
employee reaches age 65, after which term the Employment Agreement shall not be
automatically extended. The automatic renewal provision can be canceled by the
Company prior to each anniversary date of the Employment Agreements. The
Employment Agreements provide that if the Company elects not to extend the
executive's employment, the executive will be considered to have been terminated
without cause and will receive his or her base salary,
 
                                       40
<PAGE>   45
 
reduced by any salary earned by the executive from another employer, plus
certain benefits for a period of one year. The executive will also receive the
same compensation as provided above if the executive terminates his or her
employment with the Company under certain circumstances at any time within
twelve months following a Change In Control (as defined in the Employment
Agreements). The Employment Agreements also contain a restrictive covenant
pursuant to which each executive has agreed not to compete with the Company
during the time the Company is obligated to compensate him or her pursuant to
the Employment Agreement.
 
STOCK INCENTIVE PLANS
 
     1992 Stock Option Plan.  The Company has adopted, and its shareholders have
approved, the 1992 Plan pursuant to which a committee of the Board of Directors
(the "Plan Committee"), currently composed of the Members of the Compensation
Committee has the authority (i) to determine which of the eligible persons shall
be granted options to purchase shares of Class A Common Stock, (ii) to determine
whether such options shall be incentive or non-statutory stock options, (iii) to
determine the number of shares for which each option shall be granted, (iv) to
construe, interpret and administer the 1992 Plan, (v) to prescribe the terms and
provisions of each option granted, (vi) to amend the 1992 Plan, and (vii)
generally, to exercise such powers and to perform such acts as are deemed
necessary or expedient to promote the best interests of the Company.
 
     There are 918,624 shares of Class A Common Stock reserved for issuance upon
exercise of options granted under the 1992 Plan. The price per share under each
option granted shall be determined by the Board or the Plan Committee, but in
the case of incentive stock options, shall be no less than 100% of the fair
market value of the Class A Common Stock on the date of grant, and, in the case
of non-statutory options, shall in no event be less than 85% of the fair market
value of the Class A Common Stock on the date of grant.
 
     The option exercise period shall be determined by the Board or the Plan
Committee, however, incentive stock options shall not be exercisable more than
10 years from the date of grant (and five years for any individual who, at the
time of grant, owns more than 10% of the total combined voting power of all
classes of stock of the Company). No option shall be transferable otherwise than
by will or the laws of descent and distribution and an option is exercisable
during the lifetime of the optionee only by such optionee.
 
     As of the date hereof, non-qualified stock options for the purchase of
868,262 shares of Class A Common Stock have been granted to certain management
employees. The options granted will generally vest in four equal annual
installments. The options are subject to the terms of the 1992 Plan, will expire
10 years from the date of grant, and are exercisable at an average exercise
price of approximately $2.50 per share. In the event of certain fundamental
changes to the Company (including liquidation, dissolution, merger,
reorganization or sale of all or substantially all of the assets of the
Company), the stock options shall immediately vest and be fully exercisable by
the optionees. If shares subject to an option or stock appreciation right under
the 1992 Plan cease to be subject to such option or stock appreciation right
without the exercise of such option or stock appreciation right, or if shares of
restricted stock or shares underlying other stock-based awards under the 1992
Plan are forfeited or otherwise terminate without a payment being made in the
form of Class A Common Stock and without the payment of any dividends thereon,
such shares will again be available for future distribution under the 1992 Plan.
 
     1997 Stock Incentive Plan.  The Company has adopted, and its shareholders
have approved, the 1997 Plan pursuant to which the Plan Committee has the
authority to grant to key employees and consultants of the Company the following
types of awards: (1) stock options; (2) stock appreciation rights; (3)
restricted stock; and/or (4) other stock-based awards. Pursuant to the 1997
Plan, 650,000 shares of Common Stock have been reserved and will be available
for distribution, which may include authorized and unissued shares or treasury
shares. Any shares as to which an option or other award expires, lapses
unexpired, or is forfeited, terminated or canceled may become subject to a new
option or other award. The Plan will terminate on, and no award may be granted
later than December 2007, but the exercise date of awards granted prior to such
tenth anniversary may extend beyond that date. As of April 15, 1998, options for
the purchase of 470,266 shares of Class A Common Stock were outstanding at a
weighted average exercise price per share of $7.63.
 
                                       41
<PAGE>   46
 
     Incentive stock options ("ISOs") and non-qualified stock options may be
granted for such number of shares as the Plan Committee may determine and may be
granted alone, in conjunction with, or in tandem with other awards under the
1997 Plan or cash awards outside the 1997 Plan. A stock option will be
exercisable at such times and subject to such terms and conditions as the Plan
Committee will determine. However, in the case of an ISO, the term will be no
more than ten years after the date of grant (five years in the case of ISOs for
certain 10% shareholders). The option price for an ISO will not be less than
100% (110% in the case of certain 10% shareholders) of the fair market value of
the Class A Common Stock as of the date of grant and for any non-qualified stock
option will not be less than 50% of the fair market value as of the date of
grant. Stock options and stock appreciation rights granted under the 1997 Plan
may not be assigned or transferred without the prior written consent of the Plan
Committee other than (i) transfers by the optionee to a member of his or her
immediate family or a trust for the benefit of the optionee or a member of his
or her immediate family or (ii) transfers by will or by the laws of descent and
distribution.
 
     Stock appreciation rights may be granted under the 1997 Plan in conjunction
with all or part of a stock option and will be exercisable only when the
underlying stock option is exercisable. Once a stock appreciation right has been
exercised, the related portion of the stock option underlying the stock
appreciation right will terminate. Upon the exercise of a stock appreciation
right, the Plan Committee will pay to the employee or consultant in cash, Class
A Common Stock or a combination thereof (the method of payment to be at the
discretion of the Plan Committee), an amount equal to the excess of the fair
market value of the Class A Common Stock on the exercise date over the option
price, multiplied by the number of stock appreciation rights being exercised.
 
     Restricted stock awards may be granted alone, in addition to, or in tandem
with, other awards under the 1997 Plan or cash awards made outside the 1997
Plan. The provisions attendant to a grant of restricted stock may vary from
participant to participant. In making an award of restricted stock, the Plan
Committee will determine the periods during which the restricted stock is
subject to forfeiture and may provide such other awards designed to guarantee a
minimum of value for such stock. During the restricted period, the employee or
consultant may not sell, transfer, pledge, or assign the restricted stock but
will be entitled to vote the restricted stock and to receive, at the election of
the Plan Committee, cash or deferred dividends.
 
     The Plan Committee also may grant other types of awards such as performance
shares, convertible preferred stock, convertible debentures or other
exchangeable securities that are valued, as a whole or in part, by reference to
or otherwise based on the Class A Common Stock. These awards may be granted
alone, in addition to, in tandem with, stock options, stock appreciation rights,
restricted stock, or cash awards outside of the 1997 Plan. Awards will be made
upon such terms and conditions as the Plan Committee may determine.
 
     If there is a change in control or a potential change in control of the
Company (as defined in the 1997 Plan), stock appreciation rights and limited
stock appreciation rights outstanding for at least six months and any stock
options which are not then exercisable, in the discretion of the Board, may
become fully exercisable and vested. Notwithstanding the foregoing, stock
appreciation rights held by persons subject to Section 16(b) of the Exchange Act
will be automatically exercised if the change in control or potential change in
control is not within the control of such person for purposes of Rule
16b-3(e)(3) of the Exchange Act. Also, in the discretion of the Board, the
restrictions and deferral limitations applicable to restricted stock and other
stock-based awards may lapse, and such shares and awards will be deemed fully
vested. Stock options, stock appreciation rights, limited stock appreciation
rights, restricted stock and other stock-based awards, will unless otherwise
determined by the Plan Committee in its sole discretion, be cashed out on the
basis of the change in control price (as defined in the 1997 Plan and as
described below). The change in control price will be the highest price per
share paid in any transaction reported on the Nasdaq National Market or paid or
offered to be paid in any bona fide transaction relating to a change in control
or potential change in control at any time during the immediately preceding
60-day period. The Plan Committee has the discretion to determine the change in
control price, based on the parameters described in the preceding sentence.
 
     Other Stock Options.  The Company also has granted non-qualified stock
options for the purchase of 20,667 shares of Class A Common Stock to certain
non-employee directors of the Company and to the Company's Medical Director and
Associate Medical Director, of which options for 4,000 shares have been
 
                                       42
<PAGE>   47
 
exercised and/or terminated. The outstanding options granted will vest in four
equal annual installments, will expire 10 years from the date of grant, and are
exercisable at an average exercise price of approximately $4.92 per share. In
the event of certain fundamental changes to the Company (including liquidation,
dissolution, merger, reorganization or sale of all or substantially all of the
assets of the Company), the stock options shall immediately vest and be fully
exercisable by the optionees.
 
DIRECTOR AND OFFICER INDEMNIFICATION AND LIMITATION OF LIABILITY
 
     The Tennessee Business Corporation Act (the "TBCA") provides that a
corporation may indemnify any of its directors and officers against liability
incurred in connection with a proceeding if: (a) such person acted in good
faith; (b) in the case of conduct in an official capacity with the corporation,
he reasonably believed such conduct was in the corporation's best interests; (c)
in all other cases, he reasonably believed that his conduct was at least not
opposed to the best interests of the corporation; and (d) in connection with any
criminal proceeding, such person had no reasonable cause to believe his conduct
was unlawful. In actions brought by or in the right of the corporation, however,
the TBCA provides that no indemnification may be made if the director or officer
was adjudged to be liable to the corporation. The TBCA also provides that in
connection with any proceeding charging improper personal benefit to an officer
or director, no indemnification may be made if such officer or director is
adjudged liable on the basis that such personal benefit was improperly received.
Notwithstanding the foregoing, the TBCA provides that a court of competent
jurisdiction, unless the corporation's charter provides otherwise, upon
application, may order that an officer or director be indemnified for reasonable
expenses if, in consideration of all relevant circumstances, the court
determines that such individual is fairly and reasonably entitled to
indemnification, notwithstanding the fact that: (a) such officer or director was
adjudged liable to the corporation in a proceeding by or in the right of the
corporation; (b) such officer or director was adjudged liable on the basis that
personal benefit was improperly received by him; or (c) such officer or director
breached his duty of care to the corporation.
 
     The Charter and Bylaws require the Company to indemnify its directors and
officers to the fullest extent permitted by law with respect to all liability
and loss suffered and expense reasonably incurred by such person in any action,
suit or proceeding in which such person was or is made, or threatened to be
made, a party, or is otherwise involved by reason of the fact that such person
is or was a director or officer of the Company.
 
     In addition, the Charter provides that its directors shall not be
personally liable to the Company or its shareholders for monetary damages for
breach of any fiduciary duty as a director of the Company except to the extent
such exemption from liability or limitation thereof is not permitted under the
TBCA. Under the TBCA, this provision does not relieve the Company's directors
from personal liability to the Company or its shareholders for monetary damages
for breach of fiduciary duty as a director, to the extent such liability arises
from a judgment or other final adjudication establishing: (a) any breach of the
director's duty of loyalty; (b) acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; or (c) any
unlawful distributions. Nor does this provision eliminate the duty of care and,
in appropriate circumstances, equitable remedies such as injunctive or other
forms of non-monetary relief will remain available under Tennessee law. Finally,
this provision does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental laws.
 
     The Company has entered into indemnification agreements with all of its
directors and executive officers providing that it will indemnify those persons
to the fullest extent permitted by law against claims arising out of their
actions as officers or directors of the Company and will advance expenses of
defending claims against them. The Company believes that indemnification under
these agreements covers at least negligence and gross negligence by the
directors and officers and requires the Company to advance litigation expenses
in the case of actions, including shareholder derivative actions, against an
undertaking by the officer or director to repay any advances if it is ultimately
determined that the officer or director is not entitled to indemnification.
 
     The Company believes that its Charter and Bylaw provisions and
indemnification agreements are necessary to attract and retain qualified persons
as directors and officers.
 
                                       43
<PAGE>   48
 
     At present, there is no litigation or proceeding involving a director or
officer of the Company as to which indemnification is being sought, nor is the
Company aware of any threatened litigation that may result in claims for
indemnification by any officer or director.
 
     Pursuant to the Administrative Services Agreement (as hereinafter defined),
the Company will indemnify and hold AHC, its directors, officers, employees and
agents and any person who controls AHC within the meaning of the Securities Act
in the absence of gross negligence, harmless from and against any and all
liabilities, claims or damages (including the cost of investigating any claim
and reasonable attorneys' fees and disbursements) in connection with any
services performed by AHC pursuant to the Management Agreement or any
transactions or conduct in connection therewith. See "Certain Relationships and
Related Transactions -- Management and Administrative Services Agreements."
 
     The Company maintains an executive liability insurance policy which
provides coverage for its directors and officers. Under this policy, the insurer
has agreed to pay, subject to certain exclusions (including violations of
securities laws), for any claim made against a director or officer of the
Company for a wrongful act by such director or officer, but only if and to the
extent such director or officer becomes legally obligated to pay such claim or
the Company is required to indemnify the director or officer for such claim.

and (iv) each other person known to be a "beneficial owner" of more than five
percent (5%) of any class of capital stock of the Company based on information
available to the Company on April 15, 1998. Except as otherwise indicated, the

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
MANAGEMENT AND ADMINISTRATIVE SERVICES AGREEMENTS
 
     Until December 31, 1996, the Company and AHC were parties to a management
agreement dated November 30, 1992 (the "1992 Management Agreement"), pursuant to
which Henry D. Herr and Thomas G. Cigarran provided general supervision and
business management services to the Company, and AHC provided accounting,
financial and administrative services for the operations of the Company and each
of the Company's surgery centers. Under the 1992 Management Agreement, the
Company paid AHC $186,215 and $213,820 for the years ended December 31, 1995 and
1996, respectively. By letter agreement dated January 1, 1997 (the "1997 Letter
Agreement"), AHC and the Company agreed to continue, on a modified basis, the
arrangements provided under the 1992 Management Agreement. Under the 1997 Letter
Agreement, the Company paid AHC an aggregate of $382,467 for these services
during the fiscal year ended December 31, 1997. The 1997 Letter Agreement was
terminated in December 1997.
 
     In December 1997, the Company and AHC entered into an administrative
services agreement (the "Administrative Services Agreement") pursuant to which
AHC provides certain financial and accounting services to the Company and its
subsidiaries on a transitional basis, with the intent that the Company acquire
the personnel, systems and expertise necessary to become self-sufficient in the
provision of these services during the period beginning on the date of the
Administrative Services Agreement and ending one year later (or earlier if so
elected by the Company). Pursuant to the Administrative Services Agreement, AHC
provides the Company with services, including processing payroll and associated
payroll tax returns and accounts payable for the Company's corporate office,
maintaining general accounting records for the Company's corporate operations
and operations of the Company's subsidiaries (including the partnerships and
limited liability companies), preparing the Company's consolidated financial
statements, preparing the Company's corporate tax returns and tax returns for
its subsidiaries, preparing estimated tax reports, and preparing financial
statements in connection with periodic reports required to be filed by the
Company with the Commission.
 
     Under the Administrative Services Agreement, as amended, the Company pays
AHC $11,210 per month for all services provided thereunder, subject to
adjustment as the Company assumes the responsibility for such services. In
addition, in the absence of gross negligence on the part of AHC, the Company
will indemnify and hold AHC, its directors, officers, employees and agents and
any person who controls AHC within the meaning of the Securities Act harmless
from and against any and all liabilities, claims or damages (including the cost
of investigating any claim and reasonable attorneys' fees and disbursements) in
connection with any services performed by AHC or any transactions or conduct in
connection therewith.
 
ADVISORY AGREEMENTS
 
   
     Effective as of December 1997, the Company entered into advisory agreements
with Thomas G. Cigarran and Henry D. Herr (the "Advisory Agreements"), pursuant
to which Messrs. Cigarran and Herr will provide certain continuing services to
the Company through December 1999. Immediately prior to December 1997, Mr.
Cigarran served as Chairman of the Board of the Company, and Mr. Herr served as
Vice President and Secretary of the Company. Pursuant to the Advisory
Agreements, Messrs. Cigarran and Herr provide advisory services to the senior
management of the Company in the areas of strategy, operations, management and
organizational development. As compensation for these services, the Company paid
compensation of $200,000 to Mr. Cigarran and $150,000 to Mr. Herr in shares of
Class A Common Stock, which shares were issued as restricted stock pursuant to
the terms of the 1997 Plan. One-third of the shares paid as compensation vested
immediately, one-third will vest on December 3, 1998 and the remaining one-third
of the shares will vest on December 3, 1999. The Advisory Agreements provide
that Messrs. Cigarran and Herr will not sell the shares of the Class A Common
Stock received pursuant to the agreement until December 1999, subject to certain
limited exceptions. The Advisory Agreements also contain certain non-compete and
confidentiality provisions. In addition, Messrs. Cigarran and Herr are eligible
to receive compensation as Outside Directors. Messrs. Cigarran and Herr also are
entitled to indemnification as provided in the indemnification agreement that
each entered into with the Company on the Distribution Date.

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
 
     The Company is authorized to issue 20,000,000 shares of Class A Common
Stock, 4,800,000 shares of Class B Common Stock and 5,000,000 shares of
preferred stock, no par value. As of April 15, 1998, 5,145,966 shares of the
Class A Common Stock and 4,787,131 shares of the Class B Common Stock are issued
and outstanding. As of March 15, 1998, there are approximately 160 holders of
record and 2,084 beneficial owners of Class A Common Stock and approximately 95
holders of record and 2,124 beneficial owners of Class B Common Stock. The
Company may issue preferred stock from time to time in one or more series, each
such series to be so designated as to distinguish the shares thereof from the
shares of all other series and classes. The Board of Directors is vested with
the authority to divide any or all classes of authorized but unissued preferred
stock into series and to fix and determine the relative rights and preferences
of the shares of any series so established. As of April 15, 1998, stock options
for the purchase of 1,355,192 shares of Class A Common Stock are outstanding, of
which options to purchase 834,286 shares of Class A Common Stock having an
average exercise price of $2.59 per share are currently exercisable. The options
granted generally will vest in four equal annual installments, and will expire
10 years from the date of grant. In the event of certain fundamental changes to
the Company (including liquidation, dissolution, merger, reorganization or sale
of all or substantially all of the assets of the Company), the stock options
shall immediately vest and be fully exercisable by the optionees.
 
     As of April 15, 1998, the Company's executive officers and directors or
their affiliates beneficially own approximately 19.3% of the outstanding Class A
Common Stock and 16.0% of the Class B Common Stock. The holders of Class A
Common Stock and the Class B Common Stock are entitled to receive such
dividends, if any, as may be declared from time to time by the Board of
Directors in its discretion from funds legally available therefor. No dividends
have been paid to date and the management of the Company does not anticipate
dividends being paid in the foreseeable future.

<PAGE>   52
 
     The following summary of certain terms of the Company's capital stock
describes briefly the material provisions of the Charter and Bylaws, and
applicable provisions of Tennessee corporate law (including but not limited to
the TBCA).
 
     Class A Common Stock.  The holders of Class A Common Stock are entitled to
one vote per share on all matters to be submitted to a vote of the shareholders
and are not entitled to cumulative voting in the election of directors. Subject
to prior dividend rights and sinking fund or redemption or purchase rights which
may be applicable to any outstanding preferred stock, the holders of Class A
Common Stock are entitled to share ratably with the shares of Class B Common
Stock in such dividends, if any, as may be declared from time to time by the
Board of Directors in its discretion out of funds legally available therefor.
The holders of Class A Common Stock are entitled to share ratably with the
shares of Class B Common Stock in any assets remaining after satisfaction of all
prior claims upon liquidation of the Company, including prior claims of any
outstanding preferred stock. The Charter does not give holders of Class A Common
Stock any preemptive or other subscription rights, and Class A Common Stock is
not redeemable at the option of the holders, does not have any conversion
rights, and is not subject to call. The rights, preferences and privileges of
holders of Class A Common Stock are subject to, and may be adversely affected
by, the rights of holders of any other series of preferred stock that the
Company may designate and issue in the future.
 
     Class B Common Stock.  The holders of Class B Common Stock are entitled to
ten votes per share in the election and removal of the Board of Directors and
are not entitled to cumulative voting in the election and removal of such
directors. The holders of Class B Common Stock are entitled to one vote per
share on all other matters to be submitted to a vote of the shareholders. The
holders of Class B Common Stock are entitled to vote separately as a group with
respect to (i) amendments to the Charter that alter or change the powers,
preferences or special rights of the holders of Class B Common Stock so as to
affect them adversely and (ii) such other matters as may require separate group
voting under the TBCA. Subject to prior dividend rights and sinking fund or
redemption or purchase rights which may be applicable to any outstanding
preferred stock, the holders of Class B Common Stock are entitled to share
ratably with the shares of Class A Common Stock in such dividends, if any, as
may be declared from time to time by the Board of Directors in its discretion
out of funds legally available therefor. The holders of Class B Common Stock are
entitled to share ratably with the shares of Class A Common Stock in any assets
remaining after satisfaction of all prior claims upon liquidation of the
Company, including prior claims of any outstanding preferred stock. The Charter
does not give holders of Class B Common Stock preemptive or other subscription
rights, and Class B Common Stock is not redeemable at the option of the holders,
and is not subject to call. The rights, preferences and privileges of holders of
the Class B Common Stock are subject to, and may be adversely affected by, the
rights of holders of shares of any series of preferred stock that the Company
may designate and issue in the future.
 
     Dividend Policy.  The Company has never declared a cash dividend on the
shares of Common Stock and does not currently intend to declare or pay a cash
dividend on the shares of Common Stock. In addition, the payment of cash
dividends in the future will depend on the Company's earnings, financial
condition, capital needs and other factors deemed relevant by the Board of
Directors, including corporate law restrictions on the availability of capital
for the payment of dividends, the rights of holders of any series of preferred
stock that may hereafter be issued and the limitations, if any, on the payment
of dividends under any documents relating to equity investments, then-existing
credit facilities or other indebtedness. Pursuant to the Loan Agreement, the
Company is prohibited from declaring or paying any dividend to any person other
than itself or a subsidiary. It is the current intention of the Board of
Directors to retain earnings, if any, in order to finance the operations and
expansion of the Company's business.
 
     Preferred Stock.  The Company is authorized to issue 5,000,000 shares of
undesignated preferred stock, no par value. The Company established and
designated two series of shares out of the 5,000,000 authorized shares. On
November 20, 1996, the Company issued 500,000 shares of Series A Preferred Stock
for a purchase price of $6.00 per share and 416,666 shares of Series B Preferred
Stock for a purchase price of $6.00 per share. On March 3, 1998, the holders of
the Series A Preferred Stock converted their shares at fair market value into
380,952 shares of Class A Common Stock. Accordingly, the Series A Preferred
Stock has been canceled and no longer exists under the Charter. Upon completion
of this Offering, all of the shares of Series B Preferred Stock will convert
into shares of Class A Common Stock. Pursuant to the conversion terms, the
                                       48
<PAGE>   53
 
outstanding Series B Preferred Stock will be converted into approximately
607,500 shares of Class A Common Stock. Thereafter, the Series B Preferred Stock
will be canceled and cease to exist under the Charter, and the Company will have
no outstanding class of preferred stock but will have 5,000,000 shares of
preferred stock authorized and available for issuance.
 
     The authorized preferred stock may be issued from time to time in one or
more designated series or classes. Subject to the provisions of the Charter and
limitations prescribed by law, the Board of Directors, without further action or
vote by the shareholders, is authorized to establish the voting, dividend,
redemption, conversion, liquidation, and other relative provisions as may be
provided in a particular series or class. The issuance of preferred stock, while
providing flexibility in connection with possible acquisitions and other
corporate purposes, could, among other things, adversely affect the voting power
of the holders of Common Stock and, under certain circumstances, make it more
difficult for a third party to acquire, or discourage a third party from
acquiring, a majority of the outstanding voting stock of the Company. The
Company has no present intention to issue any series or class of preferred
stock.
 
TRANSFER AGENT AND REGISTRAR
 
     SunTrust Bank, Atlanta, is the transfer agent and registrar for the Common
Stock.
 
REGISTRATION AGREEMENT
 
     Certain private investors entered into a registration agreement dated April
2, 1992, as amended (the "Registration Agreement"). Pursuant thereto, the
holders of at least 66 2/3% of certain of the Registrable Shares after a
Qualified Initial Public Offering (as those terms are defined in the
Registration Agreement), may by written notice demand registration on Form S-1
or any similar long-form registration under the Securities Act of up to all of
the Registrable Shares owned by such holders. These holders of Registrable
Shares are entitled to only one such long-form demand registration. In
connection with the equity financing of preferred stock in November 1996, the
purchasers of preferred stock became parties to the Registration Agreement. As a
result, shares of Class A Common Stock issued upon conversion of the Series B
Preferred Stock have been included in the definition of Registrable Shares, and
as such, have certain registration rights. The holders of the shares of Class A
Common Stock issued upon conversion of the Series B Preferred Stock are entitled
to two demand registrations. In addition, any holder or holders of Registrable
Shares may demand registration of any or all of their Registrable Shares on or
after the date upon which the Company has become entitled as a registrant to use
Form S-3 or any similar short-form registration. This short-form demand
registration right may be invoked on unlimited occasions, provided the aggregate
offering value of the Registrable Shares requested to be registered is at least
$1,000,000. The shareholders are also entitled to unlimited "piggyback"
registration rights whenever the Company proposes to register any of its
securities under the Securities Act (other than on Forms S-4 or S-8 or any
successor forms). These "piggyback" registration rights entitle these
shareholders to include any of their Registrable Shares in any registration
statement which the Company proposes to file, including the registration
statement of which this Prospectus is a part, subject to certain limitations
generally imposed by the managing underwriter regarding the number of shares to
be included in the offering.
 
SHAREHOLDERS' AGREEMENTS
 
     Substantially all shareholders who purchased the Company's Class A Common
Stock in connection with its acquisitions of ambulatory surgery centers and
physician practices and other investments entered into shareholders' agreements
with the Company. The shareholders' agreements provide for "piggyback"
registration rights. See "Shares Eligible for Future Sale." In March 1997, the
Board of Directors waived the provision in the shareholders' agreements
prohibiting the shareholders from effecting any public sale or distribution of
such shares for 180 days following the effective date of any underwritten sale
registered under the Securities Act by the Company of its securities for its own
account. Except with respect to the registration rights of such shareholders,
the shareholders' agreements terminate upon the closing of this Offering. The
registration rights granted pursuant to the shareholders' agreements terminate
upon the later of three years after the date of the shareholders' agreement or
six months following the closing of this Offering.

CERTAIN PROVISIONS OF THE CHARTER, BYLAWS, AND TENNESSEE LAW
 
     General.  The provisions of the Charter, the Bylaws, and Tennessee
statutory law described in this section may delay or make more difficult
acquisitions or changes of control of the Company that are not approved by the
Board of Directors. Such provisions have been implemented to enable the Company,
particularly (but not exclusively) in the initial years of its existence as an
independent, publicly-owned company, to develop its business in a manner that
will foster its long-term growth without the disruption of the threat of a
takeover not deemed by the Board of Directors to be in the best interests of the
Company and its shareholders.
 
     Classified Board of Directors.  The Bylaws provide that the number of
directors shall be no fewer than three or more than 12, with the exact number to
be established by the Board of Directors and subject to change from time to time
as determined by the Board of Directors. The Charter provides for the
classification of the Board of Directors. Under the terms of the Charter, the
members of the Board of Directors are divided into three classes, serving
staggered three-year terms. As a result, one-third of the Board of Directors
will be elected each year. See "Management." This provision could prevent a
party who acquires control of a majority of the outstanding voting stock from
obtaining control of the Board of Directors until the second annual
shareholders' meeting following the date the acquiror obtains the controlling
stock interest. This provision may have the effect of discouraging a potential
acquiror from making a tender offer or otherwise attempting to obtain control of
the Company, and could also increase the likelihood that incumbent directors
will retain their positions.
 
     The Charter provides that directors may be removed only for "cause" and
only by the affirmative vote of the holders of a majority of the voting power of
all the shares of the Company's capital stock then entitled to vote in the
election of directors, voting together as a single class, unless the vote of a
special voting group is otherwise required by law. "Cause" is defined in the
Charter as: (i) a felony conviction of a director or the failure of a director
to contest prosecution for a felony; (ii) conviction of a crime involving moral
turpitude; or (iii) willful and continued misconduct or gross negligence by a
director in the performance of his or her duties as a director. The Charter also
provides that in order to call a special meeting of shareholders, written
demands of the holders of at least 15% of the voting power of each class of the
Common Stock must be received. These provisions, in conjunction with the
provision of the Bylaws authorizing the Board of Directors to fill vacant
directorships, may prevent shareholders from removing incumbent directors
without cause and filling the resulting vacancies with their own nominees.
 
     Advance Notice for Shareholder Proposals or Making Nominations at
Meetings.  The Bylaws establish an advance notice procedure for shareholder
proposals to be brought before a meeting of shareholders of the Company and for
nominations by shareholders of candidates for election as directors at an annual
meeting or a special meeting at which directors are to be elected. Subject to
any other applicable requirements, only such business may be conducted at a
meeting of shareholders as has been brought before the meeting by, or at the
direction of, the Board of Directors, or by a shareholder who has given to the
Secretary timely written notice in proper form, of the shareholder's intention
to bring that business before the meeting. The presiding officer at such meeting
has the authority to make such determinations. Only persons who are selected and
recommended by the Board of Directors, or the committee of the Board of
Directors designated to make nominations, or who are nominated by a shareholder
who has given timely written notice, in proper form, to the Secretary prior to a
meeting at which directors are to be elected will be eligible for election as
directors.
 
     To be timely, notice of nominations or other business to be brought before
any meeting must be received by the Secretary not later than 120 days in advance
of the mailing date of the Company's proxy statement for the previous year's
annual meeting or, in the case of special meetings, at the close of business on
the tenth day following the date on which notice of such meeting is first given
to shareholders.
 
     The notice of any shareholder proposal or nomination for election as
director must set forth various information required under the Bylaws. The
person submitting the notice of nomination and any person acting in concert with
such person must provide, among other things, the name and address under which
they appear on the Company's books (if they so appear) and the class and number
of shares of the Company's capital stock that are beneficially owned by them.
                                       50
<PAGE>   55
 
     Amendment of the Bylaws and Charter.  Except with respect to amendments to
the Bylaws or Charter relating to the classified structure of the Board of
Directors which are required to be approved by the affirmative vote of
two-thirds of the voting power of the shares entitled to vote in the election of
directors, the Bylaws provide that a majority of the members of the Board of
Directors who are present at any regular or special meeting or the holders of a
majority of the voting power of all shares of the Company's capital stock
represented at a regular or special meeting have the power to amend, alter,
change, repeal, or restate the Bylaws.
 
     Except as may be set forth in resolutions providing for any class or series
of preferred stock, any proposal to amend, alter, change, or repeal any
provision of the Charter requires approval by the affirmative vote of both a
majority of the members of the Board of Directors then in office and the holders
of a majority of the voting power of all of the shares of the Company's capital
stock entitled to vote on the amendments, with shareholders entitled to
dissenters' rights as a result of the charter amendment voting together as a
single class. Shareholders entitled to dissenters' rights as a result of a
charter amendment are those whose rights would be materially and adversely
affected because the amendment (i) alters or abolishes a preferential right of
the shares; (ii) creates, alters, or abolishes a right in respect of redemption;
(iii) alters or abolishes a preemptive right; (iv) excludes or limits the right
of the shares to vote on any matter, or to cumulate votes other than a
limitation by dilution through issuance of shares or other securities with
similar voting rights; or (v) reduces the number of shares held by such holder
to a fraction if the fractional share is to be acquired for cash. In general,
however, no shareholder is entitled to dissenters' rights if the security he or
she holds is listed on a national securities exchange or the Nasdaq National
Market.
 
     Tennessee Law.  The Combination Act provides, among other things, that any
corporation to which the Combination Act applies, including the Company, shall
not engage in any "business combination" with an "interested shareholder" for a
period of five years following the date that such shareholder became an
interested shareholder unless prior to such date the board of directors of the
corporation approved either the business combination or the transaction which
resulted in the shareholder becoming an interested shareholder.
 
     The Combination Act defines "business combination," generally, to mean any:
(i) merger or consolidation; (ii) share exchange; (iii) sale, lease, exchange,
mortgage, pledge, or other transfer (in one transaction or a series of
transactions) of assets representing 10% or more of (A) the market value of
consolidated assets, (B) the market value of the corporation's outstanding
shares or (C) the corporation's consolidated net income; (iv) issuance or
transfer of shares from the corporation to the interested shareholder; (v) plan
of liquidation; (vi) transaction in which the interested shareholder's
proportionate share of the outstanding shares of any class of securities is
increased; or (vii) financing arrangements pursuant to which the interested
shareholder, directly or indirectly, receives a benefit except proportionately
as a shareholder.
 
     The Combination Act defines "interested shareholder," generally, to mean
any person who is the beneficial owner, either directly or indirectly, of 10% or
more of any class or series of the outstanding voting stock, or any affiliate or
associate of the corporation who has been the beneficial owner, either directly
or indirectly, of 10% or more of the voting power of any class or series of the
corporation's stock at any time within the five year period preceding the date
in question. Consummation of a business combination that is subject to the
five-year moratorium is permitted after such period if the transaction (i)
complies with all applicable charter and bylaw requirements and applicable
Tennessee law and (ii) is approved by at least two-thirds of the outstanding
voting stock not beneficially owned by the interested shareholder, or when the
transaction meets certain fair price criteria. The fair price criteria include,
among others, the requirement that the per share consideration received in any
such business combination by each of the shareholders is equal to the highest of
(i) the highest per share price paid by the interested shareholder during the
preceding five-year period for shares of the same class or series plus interest
thereon from such date at a treasury bill rate less the aggregate amount of any
cash dividends paid and the market value of any dividends paid other than in
cash since such earliest date, up to the amount of such interest, (ii) the
highest preferential amount, if any, such class or series is entitled to receive
on liquidation, or (iii) the market value of the shares on either the date the
business combination is announced or the date when the interested shareholder
reaches the 10% threshold, whichever is higher, plus interest thereon less
dividends as noted above.
 
                                       51
<PAGE>   56
 
     The Tennessee Control Share Acquisition Act (the "Acquisition Act")
prohibits certain shareholders from exercising in excess of 20% of the voting
power in a corporation acquired in a "control share acquisition," as defined in
the Acquisition Act, unless such voting rights have been previously approved by
the disinterested shareholders of the corporation. The Company has not elected
to make the Acquisition Act applicable to it. No assurance can be given that
such election, which must be expressed in a charter or bylaw amendment, will or
will not be made in the future.
 
     The Tennessee Greenmail Act (the "Greenmail Act") prohibits the Company
from purchasing or agreeing to purchase any of its securities, at a price in
excess of fair market value, from a holder of 3% or more of any class of such
securities who has beneficially owned such securities for less than two years,
unless such purchase has been approved by the affirmative vote of a majority of
the outstanding shares of each class of voting stock issued by the Company or
the Company makes an offer of at least equal value per share to all holders of
shares of such class. The effect of the Greenmail Act may be to render more
difficult a change of control of the Company.
 
     Other Change-of-Control Provisions.  For a description of certain other
change-of-control provisions, see "Management -- Employment Agreements" and
"-- Stock Incentive Plans."
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of the Offering, the Company will have outstanding an
aggregate of 9,462,391 shares of Class A Common Stock (10,017,391 shares if the
Underwriters' over-allotment option is exercised in full) and 4,787,131 shares
of Class B Common Stock. The 3,700,000 shares of Class A Common Stock sold in
the Offering will be freely tradeable without restriction under the Securities
Act unless acquired by "affiliates" of the Company as that term is defined in
Rule 144 under the Securities Act, which sales would be subject to the resale
limitations of Rule 144. In addition, the 743,000 shares of Class A Common Stock
that were issued to holders of AHC common stock in the Distribution are freely
tradeable without restriction or further registration under the Securities Act,
unless held by affiliates of the Company (which sales also would be subject to
certain resale limitations and other restrictions under Rule 144 described
below).
    
 
   
     Of the remaining 5,019,391 outstanding shares of Class A Common Stock,
4,753,298 have not been issued in transactions registered under the Securities
Act, which means that under current law, absent registration or an exemption
from registration other than Rule 144, such shares are "restricted securities"
as that term is defined in Rule 144 under the Securities Act and are eligible
for sale or transfer only in accordance with Rule 144. Substantially all of
these shares of Class A Common Stock have met the one-year holding period
requirement of Rule 144 and therefore are eligible for sale thereunder.
    
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose share are aggregated), including an affiliate, who has beneficially owned
shares for at least one year (including, if the shares are transferred, the
holding period of any prior owner except an affiliate) is entitled to sell in
"broker's transactions" or to market makers, within any three-month period, a
number of shares that does not exceed the greater of (i) 1% of then outstanding
shares of the Class A Common Stock (approximately 51,460 shares as of April 15,
1998) or (ii) generally, the average weekly trading volume in the Class A Common
Stock during the four calendar weeks preceding the filing of a Form 144 with
respect to such sale, and subject to certain other limitations and restrictions.
In addition, a person who is not deemed to have been an affiliate of the Company
at any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years, would be entitled
to sell such shares under Rule 144(k) without regard to the volume and other
requirements described above. Shares of Class A Common Stock that would
otherwise be deemed "restricted securities" could be sold at any time through an
effective registration statement relating to such shares of Class A Common
Stock. Substantially all of the shares of Class A Common Stock that are believed
to be "restricted securities" as of the date of this Prospectus have satisfied a
one-year holding period.
 
     Pursuant to the Registration Agreement, certain shareholders of the Company
have several demand and unlimited "piggyback" registration rights. In addition,
the other shareholders of the Company are entitled to
 
                                       52
<PAGE>   57
 
unlimited "piggyback" registration rights in connection with any proposed
registration of equity securities by the Company (with certain specified
exceptions) pursuant to shareholders' agreements entered into between the
Company and these shareholders. For a more complete description of these
registration rights, see "Description of Capital Stock."
 
     As of April 15, 1998, the Company has outstanding options to purchase
1,355,192 shares of Class A Common Stock. The Company has filed a registration
statement on Form S-8 with respect to these options and approximately 834,000 of
these options are currently exercisable and may be resold in the public market.
See "Management -- Stock Incentive Plans."
 
     No assurance can be given that market sales of shares or the availability
of shares for sale will not have an effect on the market price prevailing from
time to time. Sales of substantial amounts of Class A Common Stock in the public
market, or the perception that such sales could occur, could adversely affect
the prevailing market price of the Class A Common Stock.

     In the Underwriting Agreement, the Underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all shares of Class A Common
Stock offered hereby, if any of such shares are purchased.
 
   
     The Company has been advised by the Representatives that the Underwriters
propose initially to offer the shares of Class A Common Stock to the public at
the offering price set forth on the cover page of this Prospectus and to certain
dealers at such price less a concession not in excess of $          per share.
The Underwriters may allow, and such dealers may reallow, a concession not in
excess of $          per share to certain brokers or dealers. After the
Offering, the public offering price and concessions may be changed by the
Representatives.
    
 
     The Offering of the shares of Class A Common Stock is made for delivery
when, as and if accepted by the Underwriters and subject to prior sale and to
withdrawal, cancellation or modification of the offer without notice. The
Underwriters reserve the right to reject any order for the purchase of shares.
 
     The Company has granted the Underwriters an option, exercisable not later
than 30 days after the date of the effectiveness of the Offering, to purchase up
to an aggregate of 555,000 additional shares of Class A Common Stock to cover
over-allotments, if any. To the extent the Underwriters exercise the option,
each of the Underwriters will have a firm commitment to purchase approximately
the same percentage thereof which the number of shares of Class A Common Stock
to be purchased by it shown in the table above bears to the total number of
shares in such table, and the Company will be obligated, pursuant to the option,
to sell such shares to the Underwriters. The Underwriters may exercise such
option only to cover over-allotments made in connection with the sale of the
shares of Class A Common Stock offered hereby. If purchased, the Underwriters
will sell these additional shares on the same terms as those on which the
3,700,000 shares are being offered.
 
   
     The Company and its executive officers and directors have agreed with the
Representatives that they will not, except in limited circumstances, without the
prior written consent of J.C. Bradford & Co. issue, sell, transfer, assign, or
otherwise dispose of any of the Class A Common Stock or options, warrants, or
rights to acquire Class A Common Stock owned by them prior to the expiration of
120 days from the date of this Prospectus.
    
 
   
     The Underwriting Agreement provides that the Company generally will
severally indemnify the Underwriters and their controlling persons, if any,
against certain liabilities, including civil liabilities under the Securities
Act, or will contribute to payments that the Underwriters or any such
controlling persons may be required to make in respect thereof.
    
 
     In connection with the Offering, the Underwriters and other persons
participating in the Offering may engage in transactions that stabilize,
maintain or otherwise affect the price of Common Stock. Specifically, the
Underwriters may over-allot in connection with the Offering, creating a short
position in Common Stock for their own account. To cover over-allotments or to
stabilize the price of Common Stock, the Underwriters may bid for and purchase,
shares of Common Stock in the open market. The Underwriters may also impose a
penalty bid whereby they may reclaim selling concessions allowed to an
underwriter or a dealer for distributing
                                       54

Common Stock in the Offering, if the Underwriters repurchase previously
distributed Common Stock in transactions to cover their short position, in
stabilization transactions or otherwise. Finally, the Underwriters may bid for
and purchase, shares of Common Stock in market making transactions. These
activities may stabilize or maintain the market price of Common Stock above
market levels that may otherwise prevail. The Underwriters are not required to
engage in these activities and may end any of these activities at any time.
 
     J.C. Bradford & Co. has from time to time provided investment banking and
financial advisory services to the Company for which it has received customary
compensation.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
AmSurg Corp.
Nashville, Tennessee
 
     We have audited the accompanying consolidated balance sheets of AmSurg
Corp. and subsidiaries as of December 31, 1996 and 1997, and the related
consolidated statements of operations, shareholders' equity and cash flows for
each of the years in the three-year period ended December 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. 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, such consolidated financial statements present fairly, in
all material respects, the financial position of AmSurg Corp. and subsidiaries
as of December 31, 1996 and 1997 and the results of their operations and their
cash flows for each of the years in the three-year period ended December 31,
1997 in conformity with generally accepted accounting principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
A. PRINCIPLES OF CONSOLIDATION
 
     AmSurg Corp. (the "Company"), through its wholly owned subsidiaries, owns
majority interests primarily between 51% and 70% in limited partnerships and
limited liability companies ("LLCs") which own and operate practice-based
ambulatory surgery centers and physician practices. The Company also has
majority ownership interests in other partnerships and LLCs formed to develop
additional centers. The consolidated financial statements include the accounts
of the Company and its subsidiaries and the majority owned limited partnerships
and LLCs in which the Company is the general partner or member. Consolidation of
such partnerships and LLCs is necessary as the Company has 51% or more of the
financial interest, is the general partner or majority member with all the
duties, rights and responsibilities thereof and is responsible for the
day-to-day management of the partnership or LLC. The limited partner or minority
member responsibilities are to supervise the delivery of medical services with
their rights being restricted to those which protect their financial interests,
such as approval of the acquisition of significant assets or incurring debt
which they, as physician limited partners or members, are required to guarantee
on a pro rata basis based upon their respective ownership interests. All
material intercompany profits, transactions and balances have been eliminated.
All subsidiaries and minority owners are herein referred to as partnerships and
partners, respectively.
 
B. CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents are comprised principally of demand deposits at
banks and other highly liquid short-term investments with maturities less than
three months when purchased.
 
C. OTHER CURRENT ASSETS
 
     Other current assets are comprised of prepaid expenses and other
receivables.
 
D. PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Equipment held under capital
leases is stated at the present value of minimum lease payments at the inception
of the related leases. Depreciation for buildings and improvements is recognized
under the straight-line method over 20 years, or for leasehold improvements,
over the remaining term of the lease plus renewal options. Depreciation for
moveable equipment is recognized over useful lives of five to ten years.
 
E. INTANGIBLE ASSETS
 
  Excess of Cost over Net Assets of Purchased Operations
 
     Excess of cost over net assets of purchased operations is being amortized
over 25 years. The Company has consistently assessed impairment of the excess of
cost over net assets of purchased operations and other long-lived assets in
accordance with criteria consistent with the provisions of Statement of
Financial Accounting Standard ("SFAS") No. 121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Whenever events
or changes in circumstances indicate that the carrying amount of long-term
assets may not be recoverable, management assesses whether or not an impairment
loss should be recorded by comparing estimated undiscounted future cash flows
with the assets' carrying amount at the partnership level. If the assets'
carrying amount is in excess of the estimated undiscounted future cash flows, an
impairment loss is recognized as the excess of the carrying amount over
estimated future cash flows discounted at an applicable rate. Intangibles and
other long-lived assets to be disposed of are reported at the lower of the
carrying amount or fair value less cost to sell.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Deferred Pre-opening Costs
 
     Deferred pre-opening costs consist of costs incurred for surgery centers
while under development. Deferred pre-opening costs are amortized over one year,
starting upon the commencement date of operations.
 
  Other Intangible Assets
 
     Other intangible assets consist of deferred organization costs and deferred
financing costs of the Company and the entities included in the Company's
consolidated financial statements. Deferred organization costs are amortized
over five years and deferred financing costs are amortized over the term of the
related debt.
 
F. INCOME TAXES
 
     The Company files a consolidated federal income tax return. Income taxes
are accounted for under the asset and liability method. Deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
G. EARNINGS PER SHARE
 
     Effective December 31, 1997, the Company has adopted the provisions of SFAS
No. 128 "Earnings Per Share" and has restated all previously reported amounts to
conform to the new standard. Basic earnings (loss) per share is computed by
dividing net earnings (loss) available to common shareholders by the combined
weighted average number of Class A and Class B common shares while diluted
earnings (loss) per share is computed by dividing net earnings (loss) available
to common shareholders by the weighted average number of such common shares and
potentially dilutive shares.
 
H. STOCK OPTION PLAN
 
     Prior to January 1, 1996, the Company accounted for its stock option plan
in accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25 "Accounting for Stock Issued to Employees," and related interpretations.
As such, compensation expense would be recorded on the date of grant only if the
current market price of the underlying stock exceeded the exercise price. On
January 1, 1996, the Company adopted SFAS No. 123 "Accounting for Stock-Based
Compensation," which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net earnings and pro
forma earnings per share disclosures for employee stock option grants made in
1995 and future years as if the fair-value-based method defined in SFAS No. 123
had been applied. The Company has elected to continue to apply the provisions of
APB Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No.
123.
 
I. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     SFAS No. 107, "Disclosures About Fair Value of Financial Instruments"
requires disclosure of the fair value of certain financial instruments. Cash and
cash equivalents, receivables, notes receivable and payables are reflected in
the financial statements at cost which approximates fair value. Management
believes that the carrying amounts of long-term debt approximate market value,
because it believes the terms of its borrowings approximate terms which it would
incur currently.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
J. USE OF ESTIMATES
 
     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
disclosure of 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.
 
K. RECLASSIFICATIONS
 
     Distributions to minority partners, disclosed as a financing activity in
prior years' consolidated statements of cash flows, is classified as an
operating activity in order to present cash flows provided by operating
activities more comparably to industry practices. Certain other prior year
amounts have been reclassified to conform to the 1997 presentation.
 
L. RECENT ACCOUNTING PRONOUNCEMENTS
 
     Statements of Financial Accounting Standards No. 130 "Reporting
Comprehensive Income" and No. 131 "Disclosures about Segments of an Enterprise
and Related Information" become effective for the Company for the year ended
December 31, 1998. The Company is continuing to evaluate the effects of adopting
these two statements, but does not expect the adoption of either pronouncement
to have a material effect on the Company's consolidated financial statements.
 
   
M. UNAUDITED INTERIM INFORMATION
    
 
   
     The unaudited interim financial statements include all adjustments,
consisting only of normal recurring adjustments, which management considers
necessary for a fair presentation of the financial position and results of
operations. The results of operations for the three-month period ended March 31,
1998 are not necessarily indicative of the results that may be expected for a
full year.
    
 
2.  REVENUE RECOGNITION
 
     Revenues for the years ended December 31, 1995, 1996 and 1997 are comprised
of the following:
 
<TABLE>

Revenues........................................  $22,388,739   $34,898,496   $57,413,812
                                                  ===========   ===========   ===========
</TABLE>
 
     Surgery center revenues consist of the billing for the use of the Centers'
facilities (the "usage fee") directly to the patient or third party payer. The
usage fee excludes any amounts billed for physicians' services which are billed
separately by the physicians to the patient or third party payer.
 
     Physician practice revenues consist of the billing for physician services
of the Company's two majority owned physician practices acquired in 1996 and
1997. The billings are made by the practice directly to the patient or third
party payer.
 
     Revenues from surgery centers and physician practices are recognized on the
date of service, net of estimated contractual allowances from third party
medical service payers including Medicare and Medicaid. During the years ended
December 31, 1995, 1996 and 1997 approximately 37%, 36% and 37%, respectively,
of the Company's revenues were derived from the provision of services to
patients covered under Medicare and

Medicaid. Concentration of credit risk with respect to other payers is limited
due to the large number of such payers.
 
3.  PUBLIC DISTRIBUTION OF COMMON STOCK
 
     The Company operated as a majority owned subsidiary of American Healthcorp,
Inc. ("AHC") from 1992 until the distribution by AHC to its stockholders of the
shares of the AmSurg common stock owned by it (the "Distribution") on December
3, 1997. Prior to the Distribution, the Company effected a recapitalization
pursuant to which every three shares of the Company's then outstanding common
stock were converted into one share of Class A Common Stock. Immediately
following the Recapitalization, AHC exchanged a portion of its shares of Class A
Common Stock for shares of Class B Common Stock. The principal purpose of the
Distribution was to enable the Company to have access to debt and equity capital
markets as an independent, publicly traded company. Upon the Distribution, the
Company became a publicly traded company. All shares and earnings per share data
included herein have been adjusted to reflect the recapitalization. Expenses
incurred in connection with the Distribution are reflected as distribution cost
in the consolidated statement of operations for the year ended December 31,
1997.
 
4.  ACQUISITIONS AND DISPOSITIONS
 
A. ACQUISITIONS
 
   
     The Company, through wholly owned subsidiaries and in separate
transactions, acquired a majority interest in two, four and five practice-based
surgery centers during 1995, 1996 and 1997, respectively. In addition, the
Company acquired through wholly owned subsidiaries one physician practice and
related entities in each of 1996 and 1997. Consideration paid for the acquired
interests consisted of cash, common stock, note payable or a combination
thereof. Total consideration paid in 1995, 1996 and 1997 for all acquisitions
was $4,415,000, $13,561,661 and $14,471,503, respectively, of which the Company
assigned $3,976,358, $12,289,386 and $13,738,220, respectively, to excess of
cost over net assets of purchased operations. The acquisitions were accounted
for as purchases, and the accompanying consolidated financial statements include
the results of their operations from the dates of acquisition.
    
 
     An acquisition which occurred in 1995 was structured such that if certain
operating results were not achieved, the purchase price would be adjusted.
Subsequent operations of the center did not meet the predefined levels, and the
purchase price adjustment, which is reflected as a long-term receivable in the
accompanying consolidated balance sheets, is being repaid to the Company over a
thirty-month period.
 
B. PRO FORMA INFORMATION
 
     The unaudited consolidated pro forma results for the years ended December
31, 1996 and 1997, assuming all 1996 and 1997 acquisitions had been consummated
on January 1, 1996, are as follows:

C. DISPOSITIONS
 
     In two separate transactions in 1997, the Company sold its investment in a
partnership that owned two surgery centers acquired in 1994 and a surgery center
building and equipment which the Company leased to a physician practice. In
conjunction with the sale of the surgery center building and equipment, the
Company also terminated its management agreement with the physician practice for
the surgery center in which it had no ownership interest but had managed since
1994. The net loss associated with these transactions was $1,494,000.
 
D. SUBSEQUENT ACQUISITIONS
 
     In January 1998, the Company, through a wholly owned subsidiary, acquired a
majority interest in a practiced-based surgery center. Consideration paid for

     On December 19, 1997, the Company amended its credit agreement. Under the
terms of the newly amended agreement, all borrowings outstanding under the
Company's term loan with the same lending institutions were converted to its
revolving credit facility. The borrowings under the credit facility are
guaranteed by the wholly owned subsidiaries of the Company, and in some
instances, the underlying assets of certain developed centers. The credit
agreement permits the Company to borrow up to $35,000,000 to finance the
Company's acquisition and development projects at prime or 1.75% above LIBOR or
a combination thereof, provides for a fee of .35% on unused commitments,
prohibits the payment of dividends and contains covenants relating to the ratio
of debt to net worth, operating performance and minimum net worth. The Company
was in compliance with all covenants at December 31, 1997.
 
     Certain partnerships and LLCs included in the Company's consolidated
financial statements have loans with local lending institutions which are
collateralized by certain assets of the centers with a book value of
approximately $6,300,000. The Company and the partners or members have
guaranteed payment of the loans.
 
     Principal payments required on long-term debt in the five years subsequent
to December 31, 1997 are $1,330,595, $1,118,876, $693,653, $22,957,821 and
$199,368.

</TABLE>
 
     On November 20, 1996, the Company issued to unaffiliated institutional
investors a combination of redeemable and convertible preferred stock for net
proceeds of $4,960,000. The Series A Redeemable Preferred Stock, with a stated
amount of $3,000,000, was to pay a cumulative dividend of 8% commencing November
21, 1998. Subsequent to December 31, 1997, the holders of the Series A
Redeemable Preferred Stock converted their preferred shares into 380,952 shares
of Class A Common Stock using a conversion ratio based on market price of the
Class A Common Stock pursuant to the provisions of the Company's Charter. The
Series B Convertible Preferred Stock, with a stated amount of $2,500,000, is
convertible into that number of shares of Class A Common Stock that approximates
6% of the equity of the Company determined as of November 20, 1996, with that
percentage being ratably increased to 8% of the equity of the Company if an
event of liquidity has not occurred by November 20, 2000. An event of liquidity
is defined as an initial public offering of common stock or sale of the Company
yielding net cash proceeds to the Company of at least $25,000,000, or in the
event the Company has completed a spin-off, yielding net proceeds of $20,000,000
to the Company and/or its shareholders. If such events of liquidity do not occur
by November 20, 2002, the holders of the Series B Convertible Preferred Stock
have the right to require the Company to redeem the stock at current market
price as defined by the Company's Charter. The preferred stock was recorded at
its fair value, net of issuance costs. From the time of issuance, the Series A
Redeemable Preferred Convertible Stock has been accreted toward its stated
amount, including potential dividends, over the redemption term. The Series B
Preferred Stock is not being accreted because management expects a conversion
upon an event of liquidity.
 
10.  SHAREHOLDERS' EQUITY
 
A. COMMON STOCK
 
     From the time of the Company's inception, the Company has sold Class A
Common Stock to AHC, partners and members of certain of its partnerships and
LLCs and other private investors at fair value. In addition, the Company has
issued shares of Class A Common Stock in connection with acquisitions of surgery
center assets. On December 3, 1997, the Company issued Class B Common Stock in
connection with the Distribution (see note 3). Class B Common Stock differs from
Class A Common Stock only in that it has ten votes per share in the election and
removal of directors of the Company, while the Class A Common Stock has one vote
per share. Other than the election and removal of directors of the Company, the
Class A Common Stock and the Class B Common Stock have equal voting and other
rights. The Company does not have the right to issue additional Class B Common
Stock.

     Options to purchase 1,174,849 shares of common stock at prices ranging from
$0.75 to $8.70, representing common share equivalents of 335,927 under the
treasury stock method, were outstanding at December 31, 1997 but were not
included in the computation of diluted earnings per share for the year then
ended because to do so would have been anti-dilutive to the net loss per share
available to common shareholders. The options will expire at various dates
through December 2007. The effect of the conversion of 500,000 shares of Series
A Redeemable Preferred Stock to 380,952 shares of Class A Common Stock, which
occurred subsequent to December 31, 1997 (see note 9), has also been excluded
from the computation of diluted earnings per share for the year ended December
31, 1997 because to do so would have been anti-dilutive after giving
consideration to the elimination of related accretion of preferred stock.
 
C. STOCK OPTIONS
 
     The Company has two stock option plans under which it has granted
non-qualified options to purchase shares of Class A Common Stock to employees
and outside directors. Options are granted at market value on the date of the
grant and vest over 4 years at the rate of 25% per year. Options have a term of

     The Company accounts for its stock options issued to employees and outside
directors pursuant to APB No. 25. Accordingly, no compensation expense has been
recognized in connection with the issuance of stock options. The estimated
weighted average fair values of the options at the date of grant using the
Black-Scholes option pricing model as promulgated by SFAS No. 123 in 1995, 1996
and 1997 were $1.80, $2.73 and $3.93 per share, respectively. In applying the
Black-Scholes model, the Company assumed no dividends, an expected life for the
options of seven years and a forfeiture rate of 3% in 1995, 1996 and 1997 and an
average risk free interest rate of 6.6% in 1995, 6.2% in 1996 and 6.4% in 1997.
The Company also assumed a volatility rate of 46% and 49% in 1995 and 1996,
respectively, based upon an average of comparable companies, and 54% in 1997,
based upon the volatility rate of AHC. Had the Company used the Black-Scholes
estimates to determine compensation expense for the options granted in the years
ended December 31, 1995, 1996 and 1997 net income and net income per share
attributable to common shareholders would have been reduced to the following pro
forma amounts.

12.  RELATED PARTY TRANSACTIONS
 
     Included in other operating expenses for the years ended December 31, 1995,
1996 and 1997 is $186,215, $213,820 and $382,467, respectively, paid to AHC for
management and financial services provided by AHC to the Company. These expenses
were incurred pursuant to an agreement under which AHC was paid for the services
of AHC's chief executive officer and chief financial officer as well as ongoing
accounting and tax services for surgery center and corporate operations. Upon
the Distribution, the Company issued to AHC's chief executive officer and chief
financial officer, who also serve as directors of the Company, restricted shares
of Class A Common Stock valued at approximately $350,000, in accordance with an
agreement in which they are to provide advisory services to the Company through
December 3, 1999. Deferred compensation associated with the restricted stock is
amortized over the term of the agreement.
 
     The Company also rents approximately 15,000 square feet of office space
from AHC pursuant to a sublease which expires December 1999. Included in other
operating expenses for the years ended December 31, 1996 and 1997 is $163,212
and $271,194, respectively, related to this sublease.
 
     The Company leases space for certain surgery centers from its physician
partners affiliated with its centers at rates the Company believes approximate
fair market value. Payments on these leases were $871,054, $1,205,849 and
$2,198,802 for the years ended December 31, 1995, 1996 and 1997, respectively.
 
     The Company reimburses certain of its limited partners for salaries and
benefits related to time spent by employees of their practices on activities of
the centers. Total reimbursement of such salary and benefit costs

totaled $3,538,925, $4,616,745 and $7,024,657 for the years ended December 31,
1995, 1996 and 1997, respectively.
 
     The Company believes that the foregoing transactions are in its best
interests. It is the Company's current policy that all transactions by the
Company with officers, directors, five percent shareholders and their affiliates
will be entered into only if such transactions are on terms no less favorable to
the Company than could be obtained from unaffiliated parties, are reasonably
expected to benefit the Company and are approved by a majority of the
disinterested independent members of the Company's Board of Directors.
 
13.  COMMITMENTS AND CONTINGENCIES
 
     The Company and its partnerships are insured with respect to medical
malpractice risk on a claims made basis. Management is not aware of any claims
against it or its partnerships which would have a material financial impact.
 
     The Company or its wholly owned subsidiaries, as general partners in the
limited partnerships, are responsible for all debts incurred but unpaid by the
partnership. As manager of the operations of the partnership, the Company has
the ability to limit its potential liabilities by curtailing operations or
taking other operating actions.
 
     In the event of a change in current law which would prohibit the
physicians' current form of ownership in the partnerships or LLCs, the Company
is obligated to purchase the physicians' interests in the partnerships or LLCs.
The purchase price to be paid in such event is generally the greater of the
physicians' capital account or a multiple of earnings.

15.  SUBSEQUENT EVENTS
 
   
     On March 31, 1998, the Company, through a wholly-owned subsidiary, acquired
a majority interest in a practice-based surgery center. Consideration paid for
the acquired interest was $3,125,553, consisting primarily of cash, of which the
Company assigned approximately $2,900,000 to excess of cost over net assets of
purchased operations.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     Also on March 31, 1998, a partnership in which the Company, through a
wholly-owned subsidiary, owned a 51% interest, sold certain assets comprising a
surgery center developed in 1995 for approximately $640,000, and incurred a net
loss of $42,914.
    
 
   
     On April 30, 1998, the Company through a wholly owned subsidiary, acquired
a 60% interest in a physician practice-based surgery center for approximately
$5,400,000, of which the Company assigned approximately $4,900,000 to excess of
cost over net assets of purchased operations.
    
 
   
16.  UNAUDITED SUBSEQUENT EVENTS
    
 
   
     In May 1998, the Company's Board of Directors approved a plan to dispose of
the Company's interests in the two specialty physician practices in which it
owns a majority interest as part of an overall strategy to exit the practice
management business and focus solely on the development, acquisition and
operation of ambulatory surgery centers and specialty networks. While the
Company's past strategy for network development included the ownership of
related physician practices, the Company's experience in specialty network
development has made it clear that physician practice ownership is not necessary
for the successful development of these networks. Because of this change in
strategy and the fact that the ownership of physician practices is management
intensive and produces lower profit margins than surgery centers, the Company
believes that its capital and management resources are better allocated to the
development and acquisition of surgery centers and networks. In addition, the
Company believes that the ownership of only two physician practices does not
allow for the economies of scale and growth opportunities needed to be
successful in the physician practice management business.
    
 
   
     In conjunction with the plan of disposal of these practices, the Company
will reduce the carrying value of the long-lived assets held for sale by
approximately $5,400,000 in the second quarter of 1998, based on the estimated
sales proceeds less estimated costs to sell. The Company will recognize a
deferred income tax benefit of approximately $1,800,000 associated with the
estimated loss. The remaining carrying value of the net assets of the practices
is approximately $1,700,000.
    
 
   
     The Company expects to dispose of these practice interests through a sale.
Although the Company is currently in negotiations regarding the possible sale of
one of the two practices, there are no definitive agreements or arrangements
with regard thereto. Therefore, there can be no assurance that the Company will
sell these operations; however, the Company believes that the estimated disposal
loss will be adequate in the sale of the practices.
    
 
   
     A summary of the information about the operations of the physician
practices for the years ended December 31, 1995, 1996 and 1997 and for the three
months ended March 31, 1997 and 1998 is as follows:

     Concurrent with the Company's decision to exit the physician practice
management business, one of the Company's physician practices received
notification from a payer with which it has a capitated contract for
gastroenterology services covering approximately 120,000 lives that the contract
would not be renewed beyond the June 30, 1998 anniversary date of the contract.
The payer has advised the Company that it plans to negotiate a new contract. At
this time, the Company cannot determine the outcome of these negotiations;
however, an unfavorable outcome in these negotiations may have an adverse impact
on the results of operations of the Company during the period this practice is

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                             BASIS OF PRESENTATION
 
   
     The unaudited pro forma balance sheet of AmSurg Corp. as of December 31,
1997, is presented to show the effects of an April 1998 acquisition, as if it
had occurred on March 31, 1998. The unaudited pro forma combined statements of
operations are presented to show the effects of the 1997 and 1998 acquisitions
as if they had occurred on January 1, 1997. The pro forma information is based
on the historical financial statements of the Company and the acquired centers,
giving effect to the acquisitions under the purchase method of accounting, and
the assumptions and adjustments in the accompanying notes to the pro forma
consolidated financial information. The allocation of the purchase price is
preliminary, but management does not believe it will change materially.
    
 
     The unaudited pro forma financial information does not purport to represent
what the Company's financial position or results of operations would actually
have been had the transactions in fact occurred on the dates indicated above,
nor to project the Company's financial position or results of operations for any
future date or period. In the opinion of the Company's management, all
adjustments necessary for a fair presentation have been made. This unaudited pro
forma financial information should be read in conjunction with the accompanying
notes and the consolidated financial statements of AmSurg Corp. and the related
notes included elsewhere herein.

       NOTES TO PRO FORMA CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)
 
   
     In 1997 the Company acquired majority interests in the assets and certain
liabilities comprising the business operations of five surgery centers and one
physician practice. Through April 1998, the Company acquired majority interests
in the assets and certain liabilities comprising the business operations of
three surgery centers. The accompanying pro forma consolidated balance sheet
includes the purchased assets and assumed liabilities and effects of financing,
as if a surgery center acquired in April 1998 had been acquired on March 31,
1998. The accompanying pro forma consolidated statements of operations reflects
the pro forma results of operations of the Company, as if the surgery centers
and physician practice had been acquired on January 1, 1997. Two acquisitions
were completed in early 1997, and therefore the results of their operations for
the year ended December 31, 1997 are included in the historical amounts.
    
 
PRO FORMA ADJUSTMENTS
 
     The adjustments reflected in the pro forma consolidated statement of
operations are as follows:
 
          1. To reflect cash used to fund acquisitions, net of cash not
     acquired.
 
   
          2. To reflect other current assets not acquired.
    
 
   
          3. To reflect additional excess of cost over net assets acquired
     resulting from acquisitions.
    
 
   
          4. To reflect obligations of acquired entities not assumed.
    
 
   
          5. To reflect additional long-term debt used to finance acquisitions,
     net of long-term debt not assumed.
    
 
   
          6. To reflect minority owners' interest in earnings of acquired
     operations.
    
 
   
          7. To eliminate equity of acquired entities.
    
 
   
          8. To reflect $275,000 in additional corporate general and
     administrative salary costs as a result of an increase in the number of
     centers managed, net of $120,000 in salaries based on a reduction in salary
     expense allocated to the surgery center following the acquisition, for the
     year ended December 31, 1997, and $39,000 in additional corporate general
     and administrative salary costs as a result of an increase in the number of
     centers managed for the three months ended March 31, 1998.
    
 
   
          9. To reflect $36,000 in additional miscellaneous general and
     administrative cost as a result of increase in number of centers managed,
     net of $33,000 in reduced rent expense pursuant to new lease agreements.
    
 
   
          10. To reflect amortization of additional excess of cost over net
     assets of purchased operations assets and differences in depreciation of
     purchased equipment.
    
 
   
          11. To reflect interest on acquisition-related borrowings.
    
 
   
          12. To record estimated additional federal and state income taxes at a
     combined rate of 40%, as a result of the incremental increase in earnings
     before income taxes.
    
 
   
          13. To reflect weighted average shares for stock issued in
     acquisition.
    
 
   
          14. To reflect weighted average shares for stock issued in acquisition
     and the effect of potential common shares due to existing securities
     options which are dilutive upon consideration of the adjusted pro forma net
     earnings.

                         NOTES TO FINANCIAL STATEMENTS
                          YEAR ENDED DECEMBER 31, 1997
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The South Denver Endoscopy Center, Inc. ("SDEC") began operations in 1994
in Englewood, Colorado (a suburb of Denver). SDEC is owned by a group of
shareholders who perform endoscopy procedures through their related physician
practice.
 
   
     Revenue Recognition.  Revenue consists of the billing for the use of SDEC
facilities (the "usage fee") directly to the patient or third party payer. The
usage fee excludes amounts billed for physicians' services, which are billed
separately by the physicians to the patient or third party payer. Revenues are
reported at the estimated net realizable amounts from patients, third-party
payers and others, including Medicare. Such revenues are recognized as the
related services are performed. Contractual adjustments resulting from
agreements with various organizations to provide services for amounts which
differ from billed charges, are recorded as deductions from patient service
revenues. During 1997, approximately 22% of the Center's revenues were provided
to patients covered under Medicare. Amounts which are determined to be
uncollectible are charged against the allowance for uncollectible accounts.
    
 
     Equipment.  Equipment acquisitions are recorded at cost. Depreciation is
provided over the estimated useful life and is computed using the straight-line
method. The estimated useful life for the depreciation of equipment is 5-10
years.
 
     Income Taxes.  SDEC has elected Subchapter S status of the Internal Revenue
Code, and accordingly, income taxes are the responsibility of the individual
shareholders of SDEC. Therefore, no provision for income taxes has been
reflected by SDEC.
 
     Management Estimates.  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 disclosure of 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 the estimates.
 
   
     Unaudited Interim Information.  The unaudited interim financial statements
include all adjustments, consisting only of normal recurring adjustments, which
management considers necessary for a fair presentation of the financial position
and results of operations. The results of operations for the three-month period
ended March 31, 1998 are not necessarily indicative of the results that may be
expected for a full year.
    
 
2. RELATED PARTY TRANSACTIONS
 
   
     For the year ended December 31, 1997, the shareholders of SDEC owned 100%
of SDEC as well as 100% of the South Denver Gastroenterology Center (SDGC). SDGC
provides SDEC with billing, collection, accounts payable and other bookkeeping
services. A monthly overhead charge is paid by SDEC in the amount of $2,000.
Total expense incurred for these services of $24,000 has been included in the
statement of earnings and retained earnings for the year ended December 31,
1997.
    
 
   
     In addition, the SDGC maintains a defined benefit pension plan as well as a
profit sharing plan which is open to all employees of SDEC. Employees may
participate after completing 2 years of service. SDGC is responsible for making
the contributions to the plans on behalf of the SDEC. Contributions in the
amounts of $5,933 and $10,563 were contributed to the pension plan and profit
sharing plan, respectively during 1997.

4. SUBSEQUENT EVENT
 
     Effective March 31, 1998, AmSurg Holdings, Inc. ("Holdings"), a subsidiary
of AmSurg Corp. ("AmSurg") acquired from SDEC a fifty-one percent ownership
interest in the assets and assumed certain liabilities comprising the business
operations of the endoscopy center.
 
     Pursuant to the terms of the Asset Purchase Agreement, dated as of March
18, 1998, by and among Holdings, AmSurg and SDEC, Holdings paid $3,116,290 in
cash and AmSurg issued 1,131 shares of its Class A Common Stock to SDEC.
Following the asset purchase, Holdings and SDEC contributed their respective
ownership in the assets of the center into a newly formed limited liability
company, The Englewood ASC, LLC, and received proportionate membership therein.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
    
   
    
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The Boswell Eye Center, LLC (the "Center") owns and operates an
ophthalmology surgery center in Sun City, Arizona. The Center is owned by a
group of physicians who perform ophthalmic procedures at the Center through
their related physician practices.
 
     The accompanying financial statements have been prepared on the accrual
basis of accounting and include the accounts and transactions of the Boswell Eye
Center, LLC and the Boswell Eye Institute, Inc. which are under common control.
Significant intercompany balances and transactions have been eliminated.
 
   
     Furniture and equipment.  Furniture and equipment are stated at cost less
accumulated depreciation. Depreciation for furniture and equipment is recognized
on the straight line method over five to seven years, and for leasehold
improvements over the remaining term of the lease plus renewal options.
    
 
   
     Revenue recognition.  Revenues consist of the billing of the use of the
Center's facilities (the "usage fee") directly to the patient or third-party
payer. The usage fee excludes amounts billed for physicians' services, which are
billed separately by the physicians to the patient or third-party payer.
Revenues are reported at the estimated net realizable amounts from patients,
third-party payers and others, including Medicare. Such revenues are recognized
as the related services are performed. Contractual adjustments resulting from
agreements with various organizations to provide services for amounts which
differ from billed charges, are recorded as deductions from patient service
revenues. During the years ended December 31, 1996 and 1997, approximately 52%
and 48%, respectively, of the Center's revenues were provided to patients
covered under Medicare. Amounts that are determined to be uncollectible are
charged against the allowance for uncollectible accounts.
    
 
   
     Income taxes.  The Center has elected SubChapter S status of the Internal
Revenue Code, and accordingly, income taxes are the responsibility of the
individual members of the Center. Therefore, no provision for income taxes has
been reflected in the accompanying financial statements.
    
 
     Management estimates.  The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements an the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from the estimates.
 
   
     Unaudited interim information.  The unaudited interim financial statements
include all adjustments, consisting only of normal recurring adjustments which
management considers necessary for a fair presentation of the financial position
and results of operations. The results of operations for the three-month period
ended March 31, 1998 are not necessarily indicative of the results that may be
expected for a full year.

                         NOTES TO FINANCIAL STATEMENTS
 YEARS ENDED DECEMBER 31, 1995 AND 1996 AND EIGHT MONTHS ENDED AUGUST 31, 1997
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The Endoscopy Center Inc. ("TEC") began operations in 1994 and operates two
gastrointestinal surgery centers in Independence and Kansas City, Missouri. TEC
is owned by a group of stockholders which perform gastroenterology procedures at
the centers through their related physician practice.
 
A. REVENUE RECOGNITION
 
     Revenue consists of the billing for the use of TEC's facilities (the "usage
fee") directly to the patient or third-party payor. The usage fee excludes
amounts billed for physicians' services, which are billed separately by the
physicians to the patient or third-party payor. Revenues are reported at the
estimated net realizable amounts from patients, third-party payors and others,
including Medicare and Medicaid. Such revenues are recognized as the related
services are performed. Contractual adjustments resulting from agreements with
various organizations to provide services for amounts which differ from billed
charges, are recorded as deductions from patient service revenues. During the
1995, 1996 and 1997 periods, approximately 29%, 39% and 28%, respectively, of
the Centers' revenues were provided to patients covered under Medicare and
Medicaid. Amounts, which are determined to be uncollectible, are charged against
the allowance for uncollectible accounts.
 
B. AMORTIZATION
 
     Amortization of organization cost is provided on a straight-line basis over
four years.
 
C. INCOME TAXES
 
     TEC has elected Subchapter S status of the Internal Revenue Code, and
accordingly, income taxes are the responsibility of the individual stockholders
of TEC. Therefore, no provision for income taxes has been reflected by TEC.
 
D. MANAGEMENT ESTIMATES
 
     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
disclosure of 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 the estimates.
 
E. UNAUDITED INTERIM INFORMATION
 
     The unaudited interim financial statements include all adjustments,
consisting only of normal recurring adjustments, which management considers
necessary for a fair presentation of the financial position and results of
operations. The results of operations for the eight month periods ended August
31, 1996 and 1997 are not necessarily indicative of the results that may be
expected for a full year.
 
2.  RELATED PARTY TRANSACTIONS
 
     Both centers rent equipment and furniture and one center occupies space

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Tennessee Business Corporation Act ("TBCA") provides that a corporation
may indemnify any director or officer against liability incurred in connection
with a proceeding if (i) the director or officer acted in good faith, (ii) the
director or officer reasonably believed, in the case of conduct in his or her
official capacity with the corporation, that such conduct was in the
corporation's best interest, or, in all other cases, that his or her conduct was
not opposed to the best interests of the corporation, and (iii) in connection
with any criminal proceeding, the director or officer had no reasonable cause to
believe that his or her conduct was unlawful. In actions brought by or in the
right of the corporation, however, the TBCA provides that no indemnification may
be made if the director or officer is adjudged to be liable to the corporation.
Similarly, the TBCA prohibits indemnification in connection with any proceeding
charging improper personal benefit to director or officer, if such director or
officer is adjudged liable on the basis that a personal benefit was improperly
received. In cases where the director or officer is wholly successful, on the
merits or otherwise, in the defense of any proceeding instigated because of his
or her status as a director or officer of a corporation, the TBCA mandates that
the corporation indemnify the director or officer against reasonable expenses
incurred in the proceeding. Notwithstanding the foregoing, the TBCA provides
that a court of competent jurisdiction, upon application, may order that a
director or officer be indemnified for reasonable expense if, in consideration
of all relevant circumstances, the court determines that such individual is
fairly and reasonably entitled to indemnification, whether or not the standard
of conduct set forth above was met.
 
     The Charter and Bylaws require the Company to indemnify its directors and
officers to the fullest extent permitted by law with respect to all liability
and loss suffered and expense reasonably incurred by such person in any action,
suit or proceeding in which such person was or is made, or threatened to be
made, a party, or is otherwise involved by reason of the fact that such person
is or was a director or officer of the Company.
 
     In addition, the Charter provides that the Company's directors shall not be
personally liable to the Company or its shareholders for monetary damages for
breach of any fiduciary duty as a director of the Company except to the extent
such exemption from liability or limitation thereof is not permitted under the
TBCA. Under the TBCA, this provision does not relieve the Company's directors
from personal liability to the Company or its shareholders for monetary damages
for breach of fiduciary duty as a director, to the extent such liability arises
from a judgment or other final adjudication establishing: (a) any breach of the
director's duty of loyalty; (b) acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; or (c) any
unlawful distributions. Nor does this provision eliminate the duty of care and,
in
 
                                      II-1
<PAGE>   112
 
appropriate circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Tennessee law. Finally, this
provision does not affect a director's responsibilities under any other law,
such as the federal securities laws or state or federal environmental laws.
 
     The Company has entered into indemnification agreements with all of its
directors and executive officers providing that it will indemnify those persons
to the fullest extent permitted by law against claims arising out of their
actions as officers or directors of the Company and will advance expenses of
defending claims against them. The Company believes that indemnification under
these agreements covers at least negligence and gross negligence by the
directors and officers, and requires the Company to advance litigation expenses
in the case of actions, including shareholder derivative actions, against an
undertaking by the officer of director to repay any advances if it is ultimately
determined that the officer or director is not entitled to indemnification.
 
     The Company believes that its Charter and Bylaw provisions and
indemnification agreements are necessary to attract and retain qualified persons
as directors and officers.
 
     At present, there is no litigation or proceeding involving a director or
officer of the Company as to which indemnification is being sought, not is the
Company aware of any threatened litigation that may result in claims for
indemnification by any officer or director.
 
     Pursuant to the Management Agreement, the Company will indemnify and hold
AHC, its directors, officers, employees and agents and any person who controls
AHC within the meaning of the Securities Act in the absence of gross negligence,
harmless from and against any and all liabilities, claims or damages (including
the cost of investigating any claim and reasonable attorneys' fees and
disbursements) in connection with any services performed by AHC pursuant to the
Management Agreement or any transactions or conduct in connection therewith. See
"Certain Relationships and Related Transactions -- Management and Administrative
Services Agreements."
 
     The Company has in effect an executive liability insurance policy which
will provide coverage for its directors and officers. Under this policy, the
insurer agrees to pay, subject to certain exclusions (including violations of
securities laws), for any claim made against a director or officer of the
Company for a wrongful act by such director or officer, but only if and to the
extent such director or officer becomes legally obligated to pay such claim or
the Company is required to indemnify the director or officer for such claim.
 
     The proposed form of the Underwriting Agreement filed as Exhibit 1 to this
Registration Statement contains certain provisions relating to the
indemnification of the Company and its controlling persons by the Underwriters
and relating to the indemnification of the Underwriters by the Company, its
controlling persons and the Selling Shareholders.

     in connection with the acquisitions of surgery centers and in private

          (F) On December 3, 1997, the Company issued shares of Class A Common
     Stock and Class B Common Stock in the Recapitalization, pursuant to which
     every three shares of the Company's then outstanding common stock were
     converted into one share of Class A Common Stock, and in an exchange in
     which AHC exchanged a portion of its shares of Class A Common Stock for
     shares of newly issued Class B Common Stock.
 
          (G) On March 3, 1998, the Company issued 380,952 shares of Class A
     Common Stock to the holders of the Series A Redeemable Preferred Stock upon
     conversion of such preferred stock pursuant to the terms of the Charter.
 
     The shares described in (A) through (E) above were issued without
registration under the Securities Act in reliance upon the exemptions from
registration afforded by Section 4(2) of the Securities Act and Regulation D of
the Securities Act. The shares described in (F) and (G) above were issued
without registration under the Securities Act in reliance upon the exemption
from registration afforded by Section 3(a)(9) of the Securities Act.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered hereunder, the
Registrant will, unless in the opinion of its counsel the question has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

   J.C. Bradford Financial Center
   330 Commerce Street
   Nashville, Tennessee 37201

Ladies and Gentlemen:

          AmSurg Corp., a Tennessee corporation (the "Company"), proposes to 
sell to the several underwriters named in Schedule I hereto (the
"Underwriters"), for whom you are acting as the representatives (the
"Representatives"), 3,700,000 shares (the "Firm Shares"), of the Class A Common
Stock, no par value per share (the "Class A Common Stock"), of the Company. The
Company proposes to grant to the Underwriters an option to purchase up to
555,000 additional shares of Class A Common Stock as provided for in Section 3
of this Agreement for the purpose of covering over-allotments (the "Option
Shares"). The Underwriters, severally and not jointly, are willing to purchase
the Firm Shares set forth opposite their respective names on Schedule I hereto
and their pro-rata share of the Option Shares in the event the Representatives
elect to exercise the over-allotment taken in whole or in part. The Firm Shares
and the Option Shares purchased pursuant to this Underwriting Agreement (the
"Agreement") are collectively referred to herein as the "Shares."

         1. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, each of the Underwriters that:

                  (a) The Company has filed with the Securities and Exchange
         Commission (the "Commission"), under the Securities Act of 1933, as
         amended (the "Securities Act"), a registration statement on Form S-1
         (Registration No. 333-50813), including the related preliminary
         prospectus relating to the Shares, and has filed one or more amendments
         thereto. Copies of such registration statement and any amendments,
         including any post-effective amendments, and all forms of the related
         prospectuses contained therein and any supplements thereto, have been
         delivered to you. Such registration statement, including the 


<PAGE>   2

         prospectus, Part II, all financial schedules and exhibits thereto, all
         information deemed to be a part of such registration statement pursuant
         to Rule 430A under the Rules and Regulations (as hereinafter defined)
         and any related registration statement filed pursuant to Rule 462(b)
         under the Rules and Regulations, at the time when they became
         effective, are herein referred to as the "Registration Statement," and
         the prospectus included as part of the Registration Statement on file
         with the Commission that discloses all the information that was omitted
         from the prospectus pursuant to Rule 430A under the Rules and
         Regulations on the date that the Registration Statement became
         effective and in the form filed pursuant to Rule 424(b) Rules and
         Regulations, is herein referred to as the "Final Prospectus." The
         prospectus included as part of the Registration Statement on the date
         when the Registration Statement became effective is referred to herein
         as the "Effective Prospectus." Any prospectus included in the
         Registration Statement and in any amendment thereto prior to the date
         on which the Registration Statement became effective is referred to
         herein as a "Preliminary Prospectus." For purposes of this Agreement,
         "Rules and Regulations" means the rules and regulations promulgated by
         the Commission under either the Securities Act or the Securities
         Exchange Act of 1934, as amended (the "Exchange Act"), as applicable.

                  (b) The Commission has not issued any order preventing or
         suspending the use of any Preliminary Prospectus and no proceeding for
         that purpose has been instituted or threatened by the Commission or the
         securities authority of any state or other jurisdiction. Each
         Preliminary Prospectus, at the time of filing thereof, complied with
         the requirements of the Securities Act and the Rules and Regulations,
         and did not include any untrue statement of a material fact or omit to
         state any material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading; except that the foregoing does
         not apply to statements or omissions made in reliance upon and in
         conformity with written information furnished to the Company by any
         Underwriter through J.C. Bradford & Co. ("Bradford") specifically for
         use therein (it being understood that the only information so provided
         is the information included in the last paragraph on the cover page and
         in the third, fourth, fifth and eighth paragraphs under the caption
         "Underwriting" in the Final Prospectus). When the Registration
         Statement becomes effective and at all times subsequent thereto up to
         and including the First Closing Date (as hereinafter defined), (i) the
         Registration Statement, the Effective Prospectus and the Final
         Prospectus and any amendments or supplements thereto will contain all
         statements which are required to be stated therein in accordance with
         the Securities Act and the Rules and Regulations and will comply with
         the requirements of the Securities Act and the Rules and Regulations,
         and (ii) neither the Registration Statement, the Effective Prospectus
         nor the Final 



                                       2

         Prospectus nor any amendment or supplement thereto will include any
         untrue statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading; except that the foregoing does not apply to statements
         or omissions made in reliance upon and in conformity with written
         information furnished to the Company by any Underwriter through
         Bradford specifically for use therein (it being understood that the
         only information so provided is the information included in the last
         paragraph on the cover page and in the third, fourth, fifth and eighth
         paragraphs under the caption "Underwriting" in the Final Prospectus).

                  (c) The Company is duly organized and validly existing and in
         good standing under the laws of the jurisdiction of its incorporation
         or organization with full corporate power and corporate authority to
         own its properties and conduct its business as now conducted and is
         duly qualified or authorized to do business and is in good standing in
         all jurisdictions wherein the nature of its business or the character
         of property owned or leased may require it to be authorized or
         qualified to do business, except where failure to obtain such
         authorization or qualification would not have a material adverse effect
         on the Company's condition (financial or otherwise). The Company holds
         all licenses, consents and approvals, and has satisfied all eligibility
         and other similar requirements imposed by federal, state and local
         regulatory bodies, administrative agencies or other governmental
         bodies, agencies or officials, in each case as material to the conduct
         of the business in which it is engaged as set forth in the Effective
         Prospectus.

                  (d) All of the consolidated corporations, partnerships
         (including, without limitation, general and limited partnerships) and
         limited liability companies in which the Company has a direct or
         indirect ownership interest are listed in Exhibit 21 to the
         Registration Statement (collectively, the "Subsidiaries"). Each
         Subsidiary that is a corporation (a "Corporate Subsidiary") has been
         duly organized and is validly existing as a corporation in good
         standing under the laws of the jurisdiction of its incorporation, with
         corporate power and corporate authority to own, lease and operate its
         properties and to conduct its business as described in the Registration
         Statement. Each Corporate Subsidiary is duly qualified and in good
         standing as a foreign corporation authorized to do business in each
         other jurisdiction in which the nature of its business or its ownership
         or leasing of property requires such qualification, except where the
         failure to be so qualified would not have a material adverse effect on
         the Company's condition (financial or otherwise). All of the
         outstanding shares of capital stock of each Corporate Subsidiary have
         been duly authorized and validly issued, are fully paid and
         non-assessable, were not issued in violation of or subject to any
         preemptive or similar rights, and, except as set forth in the
         Registration Statement, are owned by the Company directly, or
         indirectly through one 



                                       3
<PAGE>   4

         of the other Subsidiaries, free and clear of all security interests,
         liens, encumbrances and equities and claims; and no options, warrants
         or other rights to purchase, agreements or other obligations to issue
         or other rights to convert any obligations into shares of capital stock
         or ownership interests in any Corporate Subsidiary are outstanding.

                  (e) Each Subsidiary that is a partnership (a "Partnership")
         has been duly organized, is validly existing as a partnership under the
         laws of its jurisdiction of organization and has the partnership power
         and partnership authority to own, lease and operate its properties and
         to conduct its business as described in the Registration Statement.
         Each Partnership is duly qualified as a foreign partnership authorized
         to do business in each other jurisdiction in which the nature of its
         business or its ownership or leasing of property requires such
         qualification, except where the failure to be so qualified would not
         have a material adverse effect on the Company's condition (financial or
         otherwise). The initial capital contributions with respect to the
         outstanding units of each Partnership have been made to the
         Partnership. Except as set forth in Schedule 1(e), the general and
         limited partnership interests therein held directly or indirectly by
         the Company are owned free and clear of all security interests, liens,
         encumbrances and equities and claims; and no options, warrants or other
         rights to purchase, agreements or other obligations to issue or other
         rights to convert any obligations into ownership interests in any
         Partnership are outstanding. Each partnership agreement pursuant to
         which the Company or a Subsidiary holds an interest in a Partnership is
         in full force and effect and constitutes the legal, valid and binding
         agreement of the parties thereto, enforceable against such parties in
         accordance with the terms thereof, except as enforcement thereof may be
         limited by bankruptcy, insolvency, fraudulent conveyance or other
         similar laws affecting the enforcement of creditors' rights generally.
         There has been no material breach of or default under, and no event
         which with notice or lapse of time would constitute a material breach
         of or default under, such partnership agreements by the Company or any
         Subsidiary or, to the Company's knowledge, any other party to such
         agreements.

                  (f) Each Subsidiary that is a limited liability company (an
         "LLC") has been duly organized, is validly existing as a limited
         liability company under the laws of its jurisdiction of organization
         and has the limited liability company power and limited liability
         company authority to own, lease and operate its properties and to
         conduct its business as described in the Registration Statement. Each
         LLC is duly qualified as a foreign limited liability company authorized
         to do business in each other jurisdiction in which the nature of its
         business or its ownership or leasing of property requires such
         qualification, except where the failure to be so qualified would not
         have a material adverse effect on the Company's condition (financial or
         otherwise). The initial capital contributions with respect to the
         outstanding 



                                       4
<PAGE>   5
         membership interests of each LLC have been made to the LLC. All 
         outstanding membership interests in the LLCs were issued and sold in
         compliance with the applicable operating agreements of such LLCs and
         all applicable federal and state securities laws, and, except as set
         forth in Schedule 1(f), the membership interests therein held directly
         or indirectly by the Company are owned free and clear of all security
         interests, liens, encumbrances and equities and claims; and no options,
         warrants or other rights to purchase, agreements or other obligations
         to issue or other rights to convert any obligations into ownership
         interests in any LLC are outstanding. Each operating agreement pursuant
         to which the Company or a Subsidiary holds a membership interest in an
         LLC is in full force and effect and constitutes the legal, valid and
         binding agreement of the parties thereto, enforceable against such
         parties in accordance with the terms thereof, except as enforcement
         thereof may be limited by bankruptcy, insolvency, fraudulent conveyance
         or other similar laws affecting the enforcement of creditors' rights
         generally. There has been no material breach of or default under, and
         no event which with notice or lapse of time would constitute a material
         breach of or default under, such operating agreements by the Company or
         any Subsidiary or, to the Company's knowledge, any other party to such
         agreements.

                  (g) Except to the extent disclosed in the Prospectus, each of
         the centers described in the Prospectus as owned by the Company is
         owned and operated by a Subsidiary in which the Company directly or
         indirectly owns at least 51% of the outstanding ownership interests.
         Except as disclosed in the Prospectus, there are no consensual
         encumbrances or restrictions on the ability of any Subsidiary (i) to
         pay any dividends or make any distributions on such Corporate
         Subsidiary's capital stock, such Partnership's partnership interests or
         such LLC's membership interests or to pay any indebtedness owed to the
         Company or any other Subsidiary, (ii) to make any loans or advances to,
         or investments in, the Company or any other Subsidiary, or (iii) to
         transfer any of its property or assets to the Company or any other
         Subsidiary.

                  (h) The capitalization of the Company as of March 31, 1998 is
         as set forth under the caption "Capitalization" in the Effective
         Prospectus and the Final Prospectus, and the Company's capital stock
         conforms to the description thereof contained under the caption
         "Description of Capital Stock" in the Effective Prospectus and the
         Final Prospectus. All the issued shares of the Company's Class A Common
         Stock have been duly authorized and validly issued, and are fully paid
         and nonassessable. None of the issued shares of the Company's Class A
         Common Stock have been issued in violation of any preemptive or similar
         rights. The Shares have been duly and validly authorized and, upon
         issuance and delivery and payment therefor in the manner herein
         described, will be validly issued, fully paid and nonassessable. Except
         as set forth in the Effective 



                                       5
<PAGE>   6

         Prospectus and the Final Prospectus, (i) the Company does not have
         outstanding any options to purchase, or any rights or warrants to
         subscribe for, or any securities or obligations convertible into, or
         any contracts or commitments to issue or sell, any shares of capital
         stock, and (ii) there are no preemptive rights or other rights to
         subscribe for or to purchase, or any restriction upon the transfer of,
         any shares of capital stock pursuant to the Company's charter, bylaws
         or any agreement or other instrument to which the Company is a party or
         by which it may be bound. Neither the filing of the Registration
         Statement nor the issuance, offer or sale of the Shares as contemplated
         by this Agreement gives rise to any rights, other than those which have
         been waived or satisfied, for or relating to the registration of any
         shares of Common Stock or any other securities of the Company. The
         Underwriters will receive good and marketable title to the Shares to be
         issued and delivered hereunder, free and clear of all liens,
         encumbrances, claims, security interests, restrictions, shareholders'
         agreements, voting trusts or any other claims of third parties
         whatsoever.

                  (i) All offers and sales by the Company of the Company's
         securities prior to the date hereof were at all relevant times duly
         registered or the subject of an available exemption from the
         registration requirements of the Securities Act and were duly
         registered or the subject of an available exemption from the
         registration requirements of the applicable state securities or Blue
         Sky laws, and any private placement memoranda delivered in connection
         with offers and sales of the Company's securities prior to the date
         hereof did not include any untrue statement of a material fact or omit
         to state any material fact necessary in order to make the statements
         therein not misleading.

                  (j) The Company has full legal right, power and authority to
         enter into this Agreement and to sell and deliver the Shares to be sold
         by it to the Underwriters as provided herein, and this Agreement has
         been duly authorized, executed and delivered by the Company and
         constitutes a valid and binding agreement of the Company enforceable
         against the Company in accordance with its terms. No consent, approval,
         authorization or order of any court or governmental agency or body or
         third party is required for the performance of this Agreement by the
         Company or the consummation by the Company of the transactions
         contemplated hereby, except such as have been obtained and such as may
         be required by the National Association of Securities Dealers, Inc.
         (the "NASD") or under the Securities Act or state securities or Blue
         Sky laws in connection with the purchase and distribution of the Shares
         by the Underwriters. The issuance and sale of the Shares by 



                                       6
<PAGE>   7

         the Company, the Company's performance of this Agreement and the
         consummation of the transactions contemplated hereby will not result in
         a breach or violation of, or conflict with, any of the terms and
         provisions of, or constitute a default by the Company under, any
         indenture, mortgage, deed of trust, loan agreement, lease or other
         agreement or instrument to which the Company is a party or to which the
         Company or any of its properties is subject, the charter, bylaws or
         other governing instruments of the Company or any statute or any
         judgment, decree, order, rule or regulation of any court or
         governmental agency or body applicable to the Company or any of its
         properties. The Company is not in violation of its charter, bylaws or
         any law, administrative rule or regulation or arbitrators' or
         administrative court decree, judgment or order or in violation or
         default (there being no existing state of facts which with notice or
         lapse of time or both would constitute a default) in the performance or
         observance of any material obligation, agreement, covenant or condition
         contained in any contract, indenture, deed of trust, mortgage, loan
         agreement, note, lease, agreement or other instrument or permit to
         which it is a party or by which it or any of its properties is or may
         be bound, other than violations and defaults which would not have a
         material adverse effect on the business condition (financial or
         otherwise) of the Company. To the best knowledge of the Company, no
         other party under any such contract or other material instrument to
         which the Company and the Subsidiaries are a party is in default in any
         material respect thereunder.

                  (k) The historical consolidated financial statements, together
         with the related schedules and notes, of the Company, included in the
         Registration Statement, the Effective Prospectus and the Final
         Prospectus, comply with the requirements of the Securities Act and the
         Rules and Regulations. Such financial statements fairly present the
         financial position of the Company at the respective dates indicated in
         accordance with generally accepted accounting principles applied on a
         consistent basis for the periods indicated. The financial and
         statistical data set forth in the Effective Prospectus and the Final
         Prospectus fairly present the information set forth therein on the
         basis stated in the Effective Prospectus and the Final Prospectus.
         Deloitte & Touche, LLP, whose reports are included in the Effective
         Prospectus and the Final Prospectus, are independent accountants as
         required by the Securities Act and the Rules and Regulations. The other
         financial statements and schedules included in or as schedules to the
         Registration Statement, the Effective Prospectus and the Final
         Prospectus conform to the requirements of the Act and the Regulations
         and present fairly the information presented therein for the periods
         shown. The unaudited pro forma financial statements and notes thereto
         are in conformity with generally accepted accounting principles and are
         presented on the basis of appropriate and reasonable pro forma
         adjustments. The accounts receivable of the Company and its
         Subsidiaries have been and will continue to be adjusted to reflect
         reimbursement policies of third party payors such as Medicare,
         Medicaid, MediCal, Blue Cross/Blue Shield, private insurance companies,
         health maintenance organizations, preferred provider organizations,
         managed care systems and other third party payors. The accounts
         receivable relating to such third party payors do not and shall not
         exceed amounts the Company and its Subsidiaries are entitled to
         receive, subject to adjustments to reflect reimbursement policies of
         third party payors and normal discounts in the ordinary course of
         business. 


                  (l) Subsequent to December 31, 1997, the Company and the
         Subsidiaries have not sustained any material loss or interference with
         its business or properties from fire, flood, hurricane, accident or
         other calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, which is not
         disclosed in the Effective 





                                       7

         Prospectus and the Final Prospectus; and subsequent to the respective
         dates as of which information is given in the Registration Statement,
         the Effective Prospectus and the Final Prospectus, (i) the Company and
         the Subsidiaries have not incurred any material liabilities or
         obligations, direct or contingent, or entered into any material
         transactions not in the ordinary course of business, and (ii) there has
         not been any issuance of options, warrants or rights to purchase
         interests or the capital stock of the Company and the Subsidiaries, or
         any material adverse change, or any development involving a prospective
         material adverse change, in the general affairs, management, business,
         prospects, financial position, net worth or results of operations of
         the Company and the Subsidiaries, except in each case as described in
         the Effective Prospectus and the Final Prospectus.

                  (m) Except as described in the Effective Prospectus and the
         Final Prospectus, there is not pending, or to the knowledge of the
         Company threatened, any legal or governmental action, suit, proceeding,
         inquiry or investigation, to which the Company, the Subsidiaries or any
         of the Company's officers or directors is a party, or to which its
         property is subject, before or brought by any court or governmental
         agency or body, wherein an unfavorable decision, ruling or finding
         could prevent or materially hinder the consummation of this Agreement
         or result in a material adverse change in the business condition
         (financial or other), prospects, financial position, net worth or
         results of operations of the Company.

                  (n) 4,255,000 additional shares of Class A Common Stock
         have been approved for listing on the Nasdaq National Market (the
         "Nasdaq National Market"), subject to official notice of issuance.

                  (o) Neither the Company nor any of its directors, officers or
         controlling persons, has taken or will take, directly or indirectly,
         any action resulting in a violation of Regulation M under the Exchange
         Act, or designed to cause or result under the Exchange Act or otherwise
         in, or which has constituted or which reasonably might be expected to
         constitute, the stabilization or manipulation of the price of any
         securities of the Company or facilitation of the sale or resale of the
         Shares.

                  (p) There are no contracts or other documents required by the
         Securities Act or by the Rules and Regulations to be described in the
         Registration Statement, the Effective Prospectus or the Final
         Prospectus or to be filed as exhibits to the Registration Statement
         which have not been described or filed as required. All such contracts
         to which the Company and the Subsidiaries are a party have been duly
         authorized, executed and delivered by the Company and the Subsidiaries,
         constitute valid and binding agreements of the Company and the
         Subsidiaries and are enforceable against the Company and the
         Subsidiaries in accordance with the terms thereof.  



                                       8
<PAGE>   9

         Company and the Subsidiaries have performed all obligations required to
         be performed by them, and are neither in default nor have they received
         notice of any default or dispute under, any such contract or other
         material instrument to which they are a party or by which their
         property is bound or affected.

                  (q) Except as described in the Effective Prospectus and the
         Final Prospectus, the Company and the Subsidiaries have good and
         marketable title to all real and material personal property owned by
         them, free and clear of all liens, charges, encumbrances or defects,
         except those reflected in the financial statements hereinabove
         described. The real and personal property and buildings referred to in
         the Effective Prospectus and the Final Prospectus which are leased from
         others by the Company and the Subsidiaries are held under valid,
         subsisting enforceable leases. The Company and the Subsidiaries own or
         lease all such properties as is necessary to the Company's operations
         as now conducted.

                  (r) The Company's system of internal accounting controls is
         sufficient to meet the broad objectives of internal accounting controls
         insofar as those objectives pertain to the prevention or detection of
         errors or irregularities in amounts that would be material in relation
         to the Company's financial statements.

                  (s) The Company and the Subsidiaries have filed all foreign,
         federal, state and local income and franchise tax returns required to
         be filed through the date hereof (with the exception or any returns for
         which valid extensions for the filing have been obtained) and have paid
         all taxes shown as due thereon to the extent such taxes have become due
         and are not being contested in good faith; and there is no tax
         deficiency that has been, nor does the Company have knowledge of any
         tax deficiency which is likely to be, asserted against the Company or
         any of the Subsidiaries which, if determined adversely, could
         materially and adversely affect the earnings, assets, affairs, business
         prospects or condition (financial or other) of the Company.

                  (t) The Company and its Subsidiaries have operated and
         currently operate their business in conformity with all applicable
         laws, rules and regulations of each jurisdiction in which they conduct
         business, except where the failure to so be in compliance would not
         reasonably be expected to, individually or in the aggregate, have a 
         material adverse effect on the Company's condition (financial or
         otherwise). The Company and each of the Subsidiaries and, to the
         Company's knowledge, its affiliated physician practices hold all
         material certificates, consents, exemptions, orders, licenses,
         authorizations, accreditations, permits or other approvals or rights
         from all governmental authorities, all self-regulatory organizations,
         all governmental and private accrediting bodies and all courts and
         other tribunals (collectively, "Permits") which are necessary to own
         their properties and to conduct their businesses, including, without
         limitation, such permits as are required (i) under such federal and
         state healthcare laws as are applicable to the Company and its
         Subsidiaries and (ii) with respect to those facilities operated by the
         Company or any Subsidiary that participate in Medicare and/or Medicaid,
         to receive reimbursement thereunder, except for such failures to have
         Permits which would not reasonably be expected to, individually or in
         the aggregate, result in a material adverse effect. The Company and
         each of its Subsidiaries have fulfilled and performed all of their
         material obligations with respect to such Permits, and no event or
         change in condition has occurred which allows, or after notice or lapse
         of time would allow, revocation or termination thereof or results in
         any other material impairment of the rights of the holder of any such
         Permit, except as to such qualifications as may be set forth in the
         Prospectus and except for such failures which would not reasonably be
         expected to, individually or in the aggregate, result in a material
         adverse effect on the Company's condition (financial or otherwise).
         During the period for which financial statements are included in the
         Prospectus, denials by third party payers of claims for reimbursement
         for services rendered by the Company, its Subsidiaries or, to the
         Company's knowledge, its affiliated physician practices have not had a
         material adverse effect on the Company's condition (financial or
         otherwise). Neither the Company nor any of its Subsidiaries or, to the
         Company's knowledge, its affiliated physician practices has failed to
         file with applicable regulatory authorities any statement, report,
         information or form required by any applicable law, regulation or
         order, except where the failure to be so in compliance would not
         reasonably be expected to, individually or in the aggregate, have a
         material adverse effect on the Company's condition (financial or
         otherwise), all such filings or submissions were in material compliance
         with applicable laws when filed and no material deficiencies have been
         asserted by any regulatory commission, agency or authority with respect
         to any such filings or submissions.

<PAGE>   10

                  (u) Neither the Company nor any of its Subsidiaries is in
         violation of any federal, state, local or foreign law or regulation
         relating to occupational safety and health and other employment
         matters or to the storage, handling or transportation of hazardous or
         toxic materials, and the Company and the Subsidiaries have received all
         permits, licenses or other approvals required of them under applicable
         federal, state and foreign occupational safety and health and
         environmental laws and regulations to conduct their respective
         businesses, and the Company and the Subsidiaries are in compliance with
         all terms and conditions of any such permit, license or approval,
         except for any such violation of law or regulation, failure to receive
         required permits, licenses or other approvals or failure to comply with
         the terms and conditions of such permits, licenses or approvals which
         would not result in a material adverse change in the condition,
         financial or otherwise, or in the earnings, business affairs or
         prospects of the Company.

                  (v) Neither the Company nor any of its Subsidiaries has failed
         to file with the applicable regulatory authorities any statements,
         reports, information or forms required by all applicable laws,
         regulations or orders where the failure to file the same would have a
         material adverse effect on the Company; all such filings or submissions
         were in material compliance with applicable laws when filed, and no
         material deficiencies have been asserted by any regulatory commission,
         agency or authority with respect to such filings or submissions.
         Neither the Company nor any of its Subsidiaries has failed to maintain
         in full force and effect any licenses, registrations or permits
         necessary or proper for the conduct of their respective businesses, or
         received any notification that any revocation or limitation thereof is
         threatened or pending, and, except as disclosed in the Effective
         Prospectus and the Final Prospectus, there is not to the knowledge of
         the Company pending any change under any law, regulation, license or
         permit which could materially adversely affect the business,
         operations, properties or business prospects of the Company and the
         Subsidiaries. Neither the Company nor any of its Subsidiaries has
         received any notice of violation of or been threatened with a charge of
         violating or, to the Company's knowledge, is under investigation with
         respect to a possible violation of any provision of any law, regulation
         or order.

                  (w) No labor dispute exists or is imminent with any of the
         employees of the Company and the Subsidiaries or otherwise which could
         materially adversely affect the Company. The Company is not aware of
         any existing or imminent labor disturbance by employees of the Company
         and the Subsidiaries which could be expected to materially adversely
         affect the condition (financial or otherwise), results of operations,
         properties, affairs, management, business affairs or business prospects
         of the Company.

                  (x) The Company and its Subsidiaries and, to the Company's
         knowledge, its affiliated practice groups own or possess all licenses,
         patents, copyrights, trademarks, service marks and trade names
         currently employed by them in connection with the businesses currently
         operated or proposed to be operated by them, and none of such parties
         has received any notice of infringement of or conflict with asserted
         rights of others with respect to any of the foregoing which, alone or
         in the aggregate, if the subject of an unfavorable decision, ruling or
         finding, would result in any material adverse change in the condition,
         financial or otherwise, or in the earnings, business affairs or
         business prospects of the Company.

                  (y) The Company and its Subsidiaries are insured by insurers
         of recognized financial responsibility against such losses and risks
         and in such amounts as are prudent and customary in the businesses in
         which they are engaged and in which they propose to engage, and the
         Company has no reason to believe that it and the Subsidiaries will not
         be able to renew its existing insurance coverage as and when such
         coverage expires or to obtain similar coverage from similar insurers as
         may be necessary to continue its business.

                  (z) Neither the Company, its Subsidiaries, nor, to the
         Company's knowledge, any director, officer, agent, employee or other
         person acting on behalf of the Company has (i) used, or authorized the
         use of, any corporate or other funds for unlawful payments,
         contributions, gifts or entertainment, (ii) made unlawful expenditures
         relating to political activity to government officials or others, or
         (iii) established or maintained any unlawful or unrecorded funds in
         violation of any federal, state, local or foreign law or regulation,
         including Section 30A of the Exchange Act. Neither the Company nor, to
         the Company's knowledge, any director, officer, agent, employee or
         other person acting on behalf of the Company has accepted or received
         any unlawful contributions, payments, gifts or expenditures.

                  (aa) The Company is not, will not become as a result of the
         transactions contemplated hereby, and does not intend to conduct its
         business in a manner that would cause it to become, an "investment
         company" or a company "controlled" by an "investment company" within
         the meaning of the Investment Company Act of 1940.

                  (bb) Except as disclosed in the Registration Statement and the
         Effective Prospectus, there are no business relationships or related
         party transactions required to be disclosed therein by Item 404 of
         Regulation S-K promulgated by the Commission.

                  (cc) None of the Company nor any of its officers or directors,
         or, to the knowledge of the Company, any employee, member of an LLC,
         partner of a Partnership, contractor or other agent of the Company or
         any of its Subsidiaries or affiliated physician practices, has ever
         been excluded from participation in a federal health care program for
         the provision of items or services for which payment may be made under
         such a program, nor has engaged on behalf of the Company in any of the
         following: (i) knowingly and willfully making or causing to be made a
         false statement or representation of a material fact in any
         applications for any benefit or payment under the Medicare or Medicaid
         program or from any third party (where applicable federal or state law
         prohibits such payments to third parties); (ii) knowingly and willfully
         making or causing to be made any false statement or representation of a
         material fact for use in determining rights to any benefit or payment
         under the Medicare or Medicaid program or from any third party (where
         applicable federal or state law prohibits such payments to third
         parties); (iii) failing to disclose knowledge by a claimant of the
         occurrence of any event affecting the initial or continued right to any
         benefit or payment under the Medicare or Medicaid program or from any
         third party (where applicable federal or state law prohibits such
         payments to third parties) on its own behalf or on behalf of another,
         with intent to secure such benefit or payment fraudulently; (iv)
         knowingly and willfully offering, paying, soliciting or receiving any
         remuneration (including any kickback, bribe or rebate), directly or
         indirectly overtly or covertly, in cash or in kind (a) in return for
         referring an individual to a person for the furnishing or arranging for
         the furnishing of any item or service for which payment may be made in
         whole or in part by Medicare or Medicaid or any third party (where
         applicable federal or state law prohibits such payments to third
         parties), or (b) in return for purchasing, leasing or ordering or
         arranging for or recommending the purchasing, leasing or ordering of
         any good, facility, service, or item for which payment may be made in
         whole or in part by Medicare or Medicaid or any third party (where
         applicable federal or state law prohibits such payments to third
         parties.

         2.       Purchase, Sale and Delivery of the Shares.

                  (a) On the basis of the representations, warranties,
         agreements and covenants herein contained and subject to the terms and
         conditions herein set forth, the Company agrees to sell to the several
         Underwriters 3,700,000 Firm Shares, and each of the Underwriters,
         severally and not jointly, agrees to purchase at a purchase price of
         $______ per share, the number of Firm Shares set forth opposite such
         Underwriter's name in Schedule I hereto, plus such additional number
         of Firm Shares which such Underwriter may become obligated to purchase
         pursuant to Section 8 hereof.

                  (b) The Company hereby grants to the Underwriters an option to
         purchase, solely for the purpose of covering over-allotments in the
         sale of Firm Shares, all or any portion of the Option Shares at the
         purchase price per share set forth above. The option granted hereby may
         be exercised as to all or any part of the Option Shares at any time
         within 30 days after the date of the Final Prospectus. The Underwriters
         shall not be under any obligation 



                                       13
<PAGE>   14

         to purchase any Option Shares prior to the exercise of such option. The
         option granted hereby may be exercised by the Underwriters by Bradford
         giving written notice to the Company setting forth the number of Option
         Shares to be purchased and the date and time for delivery of and
         payment for such Option Shares and stating that the Option Shares
         referred to therein are to be used for the purpose of covering
         over-allotments in connection with the distribution and sale of the
         Firm Shares. If such notice is given prior to the First Closing Date
         (as hereinafter defined), the date set forth therein for such delivery
         and payment shall not be earlier than two full business days thereafter
         or the First Closing Date, whichever occurs later. If such notice is
         given on or after the First Closing Date, the date set forth therein
         for such delivery and payment shall not be earlier than three full
         business days thereafter. In either event, the date so set forth shall
         not be more than four full business days after the date of such notice.
         The date and time set forth in such notice is herein called the "Option
         Closing Date." Upon exercise of the option, the Company shall become
         obligated to sell to the Underwriters, and, subject to the terms and
         conditions herein set forth, the Underwriters shall become obligated to
         purchase, for the account of each Underwriter, from the Company,
         severally and not jointly, the number of Option Shares specified in
         such notice. Option Shares shall be purchased for the accounts of the
         Underwriters in proportion to the number of Firm Shares set forth
         opposite such Underwriter's name in Schedule I hereto, except that the
         respective purchase obligations of each Underwriter shall be adjusted
         so that no Underwriter shall be obligated to purchase fractional Option
         Shares.

                  (c) Certificates in definitive form for the Firm Shares which
         each Underwriter has agreed to purchase hereunder shall be delivered by
         or on behalf of the Company to the Underwriters for the account of such
         Underwriter against payment by such Underwriter or on its behalf of the
         purchase price therefor by wire transfer of immediately available funds
         to the order of the Company, at the offices of Bradford, 330 Commerce
         Street, Nashville, Tennessee 37201, or at such other place as may be
         agreed upon by Bradford and the Company, at 10:00 A.M., Nashville time,
         on the third full business day after this Agreement becomes effective,
         or, at the election of the Underwriters, on the fourth full business
         day after this Agreement becomes effective, if it becomes effective
         after 4:30 P.M. Eastern time, or at such other time not later than the
         seventh full business day thereafter as the Underwriters and the
         Company may determine, such time of delivery against payment being
         herein referred to as the "First Closing Date." The First Closing Date
         and the Option Closing Date are herein individually referred to as the
         "Closing Date" and collectively referred to as the "Closing Dates."
         Certificates in definitive form for the Option Shares which each
         Underwriter shall have agreed to purchase hereunder shall be similarly
         delivered by or on behalf of the Company on the Option Closing Date.
         The certificates in definitive form for the Shares to be delivered will
         be in good delivery form 



                                       14
<PAGE>   15

         and in such denominations and registered in such names as Bradford may
         request not less than 48 hours prior to the First Closing Date or the
         Option Closing Date, as the case may be. Such certificates will be made
         available for checking and packaging at a location in New York, New
         York as may be designated by Bradford, at least 24 hours prior to the
         First Closing Date or the Option Closing Date, as the case may be. It
         is understood that Bradford may (but shall not be obligated to) make
         payment on behalf of any Underwriter or Underwriters for the Shares to
         be purchased by such Underwriter or Underwriters. No such payment shall
         relieve such Underwriter or Underwriters from any of its or their
         obligations hereunder.

         3. Offering by the Underwriters. After the Registration Statement
becomes effective, the several Underwriters propose to offer for sale to the
public the Firm Shares and any Option Shares which may be sold at the price and
upon the terms set forth in the Final Prospectus.

         4. Covenants of the Company. The Company covenants and agrees with each
of the Underwriters that:

                           (i) The Company shall comply with the provisions of
                  and make all requisite filings with the Commission pursuant to
                  Rules 424 and 430A of the Rules and Regulations and shall
                  notify the Representatives promptly (in writing, if requested)
                  of all such filings. The Company shall notify the
                  Representatives promptly of any request by the Commission for
                  any amendment of or supplement to the Registration Statement,
                  the Effective Prospectus or the Final Prospectus or for
                  additional information; the Company shall prepare and file
                  with the Commission, promptly upon the Underwriters' request,
                  any amendments of or supplements to the Registration
                  Statement, the Effective Prospectus or the Final Prospectus
                  which, in the Underwriters' opinion, based on the advice of
                  legal counsel, may be necessary or advisable in connection
                  with the distribution of the Shares; and the Company shall not
                  file any amendment of or supplement to the Registration
                  Statement, the Effective Prospectus or the Final Prospectus
                  which is not approved by the Representatives after reasonable
                  notice thereof. The Company shall advise the Representatives
                  promptly of the issuance by the Commission or any jurisdiction
                  or other regulatory body of any stop order or other order
                  suspending the effectiveness of the Registration Statement,
                  suspending or preventing the use of any Preliminary
                  Prospectus, the Effective Prospectus or the Final Prospectus
                  or suspending the qualification of the Shares for offering or
                  sale in any jurisdiction, or of the institution of any
                  proceedings for any such purpose; and the Company shall use
                  its best efforts to prevent the 



                                       15
<PAGE>   16

                  issuance of any stop order or other such order and, should a
                  stop order or other such order be issued, to obtain as soon as
                  possible the lifting thereof.

                           (ii)  The Company will take or cause to be taken, in
                  cooperation with the Underwriters and their counsel, all
                  necessary action and furnish to whomever the Representatives
                  direct, such information as may be reasonably required in
                  qualifying the Shares for offer and sale under the securities
                  or Blue Sky laws of such jurisdictions as the Underwriters may
                  designate and will continue such qualifications in effect for
                  as long as may be reasonably necessary to complete the
                  distribution of the Shares. The foregoing notwithstanding,
                  the Company shall not be required to qualify as a foreign
                  corporation or to take any action which would subject it to
                  general service of process in any jurisdiction where it is not
                  presently qualified or where it would be subject to taxation
                  as a foreign corporation.

                           (iii) Within the time during which a Final Prospectus
                  relating to the Shares is required to be delivered under the
                  Securities Act, the Company shall comply with all requirements
                  imposed upon it by the Securities Act, as now and hereafter
                  amended, and by the Rules and Regulations, as from time to
                  time in force, so far as is necessary to permit the
                  continuance of sales of or dealings in the Shares as
                  contemplated by the provisions hereof and the Final
                  Prospectus. If during such period any event occurs as a result
                  of which the Final Prospectus as then amended or supplemented
                  would include an untrue statement of a material fact or omit
                  to state a material fact necessary to make the statements
                  therein, in the light of the circumstances then existing, not
                  misleading, or if during such period it is necessary to amend
                  the Registration Statement or supplement the Final Prospectus
                  to comply with the Securities Act, the Company shall promptly
                  notify the Representatives and shall amend the Registration
                  Statement or supplement the Final Prospectus (at the expense
                  of the Company) so as to correct such statement or omission or
                  effect such compliance.

                           (iv)  The Company will furnish without charge to the
                  Representatives and make available to the Underwriters copies
                  of the Registration Statement (four of which shall be signed
                  and shall be accompanied by all exhibits), each Preliminary
                  Prospectus, the Effective Prospectus and the Final Prospectus,
                  and all amendments and supplements thereto, including any
                  prospectus or supplement prepared after the effective date of
                  the Registration Statement, in each case as soon as available
                  and in such quantities as the Underwriters may reasonably
                  request.

                           (v)   The Company will (A) deliver to the
                  Representatives at such office or offices as the
                  Representatives may designate as many copies of the
                  Preliminary Prospectus and Final Prospectus as the
                  Representatives may reasonably request, and (B) for a period 
                  of not more than nine months after the Registration Statement
                  becomes effective, 



                                       16
<PAGE>   17

                  send to the Representatives as many additional copies of the
                  Final Prospectus and any supplement thereto as the 
                  Representatives may reasonably request.

                           (vi)   The Company shall make generally available to
                  its security holders, in the manner contemplated by Rule
                  158(b) under the Rules and Regulations as promptly as
                  practicable and in any event no later than 45 days after the
                  end of its fiscal quarter in which the first anniversary of
                  the effective date of the Registration Statement occurs, an
                  earnings statement satisfying the provisions of Section 11(a)
                  of the Securities Act covering a period of at least 12
                  consecutive months beginning after the effective date of the
                  Registration Statement.

                           (vii)  The Company will apply the net proceeds from
                  the sale of the Shares to be sold by it as set forth under the
                  caption "Use of Proceeds" in the Final Prospectus and will
                  timely report such use of proceeds in its periodic reports
                  filed pursuant to sections 13(a) and 15(d) of the Exchange Act
                  in accordance with Rule 463 of the Securities Act or any
                  successor provision.

                           (viii) During a period of five years from the
                  effective date of the Registration Statement or such longer
                  period as the Representatives may reasonably request, the
                  Company will furnish to the Representatives copies of all
                  reports and other communications (financial or other)
                  furnished by the Company to its shareholders and, as soon as
                  available, copies of any reports or financial statements
                  furnished or filed by the Company to or with the Commission or
                  any national securities exchange or over-the-counter market on
                  which any class of securities of the Company may be listed for
                  trading.

                           (ix)   The Company will, from time to time, after the
                  effective date of the Registration Statement file with the
                  Commission such reports as are required by the Securities Act,
                  the Exchange Act and the Rules and Regulations, and shall also
                  file with foreign, state and other governmental securities
                  commissions in jurisdictions where the Shares have been sold
                  by the Underwriters (as the Representatives shall have advised
                  the Company in writing) such reports as are required to be
                  filed by the securities acts and the regulations of those
                  jurisdictions.

                           (x)    Except pursuant to this Agreement or with the
                  Representatives' written consent, for a period of 120 days
                  from the effective date of the Registration Statement, the
                  Company will not, 



                                       17
<PAGE>   18

                  and the Company has provided agreements (the "Lockup
                  Agreements") executed by each of its officers, directors and
                  5% or greater Shareholders providing that for a period of 120
                  days from the effective date of the Registration Statement,
                  such person will not, offer for sale, sell (other than the
                  issuance by the Company of shares of Common Stock pursuant to
                  acquisitions or the exercise of options granted pursuant to
                  existing employee benefit plans and agreements), grant any
                  options (other than pursuant to existing employee benefit
                  plans and agreements), rights or warrants with respect to any
                  shares of Common Stock, securities convertible into shares of

                  otherwise dispose of, directly or indirectly, any shares of
                  Common Stock or such other securities or capital stock.

                           (xi)   Neither the Company nor any of its directors,
                  officers or controlling persons, has taken or will take,
                  directly or indirectly, any action resulting in a violation of
                  Regulation M under the Exchange Act, or designed to cause or
                  result in, or which has constituted or which reasonably might
                  be expected to constitute, the stabilization or manipulation
                  of the price of any securities of the Company or facilitation
                  of the sale or resale of the Shares.

                           (xii)  The Company will either conduct its business
                  and operations as described in the Final Prospectus or, if the
                  Company makes any material change to its business or
                  operations as so conducted, promptly disclose such change
                  generally to the Company's security holders.

                  thereto; to such counsel's knowledge, the partnership 
                  interests in the Partnerships held directly or indirectly by
                  the Company are free and clear of all liens, encumbrances and

                  in the Partnerships are outstanding.

                           (iii) Each of the LLCs has been duly organized and is

                  qualified as a foreign limited liability company in those
                  states listed on a schedule thereto; to such counsel's
                  knowledge, the membership interests in the LLCs held directly

                           (iv)  As of the date specified therein, the Company
                  had historically authorized and issued capital stock as set
                  forth under the caption "Capitalization" in the Final
                  Prospectus. All of the outstanding shares of Common Stock have
                  been duly authorized and are validly issued, fully paid and
                  nonassessable, and the Shares to be sold by the Company have
                  been duly authorized, and upon issuance thereof and payment
                  therefor as provided herein, will be validly issued, fully
                  paid and nonassessable; none of the issued shares have been
                  issued in violation of or subject to any preemptive rights
                  provided for by law, any agreement known to such counsel or
                  the Company's charter. To such counsel's knowledge, the
                  Company does not have outstanding any options to purchase, or
                  any rights or warrants to subscribe for, or any securities or
                  obligations convertible into, or any 



                                       21
<PAGE>   22

                  contracts or commitments to issue or sell any shares of
                  capital stock, and there are no preemptive rights or other
                  rights to subscribe for or purchase any shares of the capital
                  stock of the Company, or any restriction upon the transfer of,
                  the Shares pursuant to the Company's charter or bylaws or any
                  agreement or other instrument known to such counsel to which
                  the Company is a party or by which it may be bound, except as
                  described in the Effective Prospectus and Final Prospectus. To
                  such counsel's knowledge, neither the filing of the
                  Registration Statement nor the offer or sale of the Shares as
                  contemplated by this Agreement gives rise to any rights, other
                  than those which have been waived or satisfied, for or
                  relating to the registration of any Common Stock or any other
                  securities of the Company. The Underwriters will receive good
                  and marketable title to the Shares to be issued and delivered
                  by the Company pursuant to this Agreement, free and clear of
                  all liens, encumbrances, claims, security interests,
                  restrictions, shareholders agreements, voting trusts and the
                  rights of any third party whatsoever. The capital stock of the
                  Company and the Shares conform to the description thereof
                  contained in the Final Prospectus. All offers and sales of the
                  Company's interests and securities prior to the date hereof
                  were made in reliance upon available exemptions from the
                  registration requirements of the Securities Act and the
                  registration requirements of applicable state securities or
                  Blue Sky laws or, if not exempt, properly registered in
                  compliance with such laws.

                           (v) No consent, approval, authorization or order of
                  any court or governmental agency or body or, to such counsel's
                  knowledge, third party is required for the performance of this
                  Agreement by the Company or the consummation by the Company of
                  the transactions contemplated hereby, except such as have been
                  obtained under the Securities Act and such as may be required
                  by the NASD and under state securities or Blue Sky laws in
                  connection with the purchase and distribution of the Shares by
                  several Underwriters, as to which such counsel need not
                  express an opinion. The performance of this Agreement by the
                  Company and the consummation by the Company of the
                  transactions contemplated hereby will not conflict with or
                  result in a breach or violation by the Company or any of its
                  Subsidiaries of any of the terms or provisions of, or
                  constitute a default by the Company or any of its Subsidiaries
                  under, any material contract, agreement, indenture, mortgage,
                  deed of trust, loan agreement, lease or other agreement or
                  instrument to which either the Company or any of its
                  Subsidiaries is a party or to which either the Company or any
                  of its Subsidiaries or their properties is subject, the
                  charter or bylaws of the Company, any statute, or any 



                                       22
<PAGE>   23
                  judgment, decree, order, rule or regulation of any court or
                  governmental agency or body applicable to the Company and
                  known to such counsel (except that such counsel need not
                  express an opinion as to whether performance of the
                  indemnification provisions of this Agreement would be
                  permitted).

                           (vi) The Company has full legal right and all
                  corporate power and authority to enter into this Agreement and
                  to issue, sell and deliver the Shares to be sold by it to the
                  Underwriters as provided herein, and this Agreement has been
                  duly authorized, executed and delivered by the Company and
                  constitutes the valid and legally binding obligation of the
                  Company enforceable against the Company in accordance with its
                  terms.

                           (vii) Except as described in the Final Prospectus,
                  to such counsel's knowledge, there is not pending or
                  threatened, any action, suit, proceeding, inquiry or
                  investigation, to which the Company or any of the Subsidiaries
                  are a party, or to which the property of the Company or any of
                  the Subsidiaries are subject, before or brought by any court
                  or governmental agency or body, which, if determined adversely
                  to the Company or any of the Subsidiaries, would result in any
                  material adverse change in the business, financial position,
                  net worth or results of operations, or would materially
                  adversely affect the properties or assets, of the Company or
                  any of the Subsidiaries.

                           (viii)  To such counsel's knowledge, no default
                  exists, and no event has occurred which with notice or after
                  the lapse of time to cure or both, would constitute a default,
                  in the due performance and observance of any term, covenant or
                  condition of any material indenture, mortgage, deed of trust,
                  loan agreement, lease or other agreement or instrument to
                  which either the Company or any of its Subsidiaries is a party
                  or to which their respective properties are subject, or of the
                  charter or bylaws of the Company.

                           (ix) The Company is not an "investment company" or
                  an entity "controlled" by an "investment company," as such
                  terms are defined in the Investment Company Act of 1940, as
                  amended.

                           (x) The Registration Statement and all 
                  post-effective amendments thereto have become effective under
                  the Securities Act, and, to such counsel's knowledge, no stop
                  order suspending the effectiveness of the Registration
                  Statement has been issued and no proceedings for that purpose
                  have been instituted or are threatened, pending or
                  contemplated by the Commission. All filings required by Rule
                  424 and Rule 430A of the 



                                       23
<PAGE>   24

                  Rules and Regulations have been made; the Registration
                  Statement, the Effective Prospectus and Final Prospectus, and
                  any amendments or supplements thereto, as of their respective
                  effective or issue dates, complied as to form in all material
                  respects with the requirements of the Securities Act and the
                  Rules and Regulations; the descriptions in the Registration
                  Statement, the Effective Prospectus and the Final Prospectus
                  of statutes, regulations, legal and governmental proceedings,
                  and contracts and other documents are accurate in all material
                  respects and present fairly in all material respects the
                  information purported to be summarized; and counsel does not
                  know of any pending or threatened legal or governmental
                  proceedings, statutes or regulations required to be described
                  in the Final Prospectus which are not described as required
                  nor of any contracts or documents of a character required to
                  be described in the Registration Statement or the Final
                  Prospectus or to be filed as exhibits to the Registration
                  Statement which are not described and filed as required.

                             (xi) To such counsel's knowledge in the course of
                  their representation, neither the Company, its Subsidiaries
                  nor any of the affiliated physician practices is in violation
                  of any material healthcare laws applicable to the Company or
                  any of the Subsidiaries or any of the affiliated physician
                  practices or of any decree of any court or governmental agency
                  or body having jurisdiction over the Company or any of the
                  Subsidiaries. To such counsel's knowledge, neither the
                  Company, its Subsidiaries nor any of the affiliated physician
                  practices is in violation of applicable state licensure,
                  Medicare or Medicaid requirements, which violation is likely
                  to have a material adverse effect on the Company's condition
                  (financial or otherwise).

                           (xii) To such counsel's knowledge, the Company and
                  each of its Subsidiaries have all necessary Permits (except
                  where the failure to have such Permits, individually or in the
                  aggregate, would not have a material adverse effect on the

                  to receive reimbursement thereunder.

                           (xiii) The descriptions of statutes and regulations

         In addition to the matters set forth above, such opinion shall also
include a statement to the effect that nothing has come to the attention of such
counsel which leads them to believe that the Registration Statement, the
Effective Prospectus and the Final Prospectus or any amendment or supplement
thereto contains an untrue statement of a material fact or omits to state a
material fact necessary to make the statements therein not misleading in light
of the circumstances under which they were made (except that such counsel need
express no view as to financial statements, schedules and other financial or
statistical information included therein).

         The opinion to be rendered pursuant to paragraph (c) may be limited to
federal law, and as to foreign and state law matters, to the laws of the states
or jurisdictions in which such counsel is admitted to practice. Such counsel may
rely upon opinions of other counsel in rendering such opinions provided that
such counsel shall state that they believe that both the Representatives and
they are justified in relying upon such opinions and that such counsel is
reasonably satisfactory to you.

                  (d) The Underwriters shall have received an opinion or
         opinions, dated the Closing Date, of Waller Lansden Dortch & Davis, A
         Professional Limited Liability Company, counsel for the Underwriters,
         with respect to the Registration Statement and the Final Prospectus,
         and such other related matters as the Underwriters may require, and the
         Company shall have furnished to such counsel such documents as they may
         reasonably request for the purpose of enabling them to pass upon such
         matters.

                  (e) The Representatives shall have received from Deloitte &
         Touche, LLP, a letter dated the date hereof and, at the Closing Date, a
         second letter dated the Closing Date, in form and substance
         satisfactory to the Representatives, stating that they are independent
         public accountants with respect to the Company and its subsidiaries
         within the meaning of the Securities Act and the applicable Rules and
         Regulations, and containing statements and information of the type
         ordinarily included in accountants' "comfort letters" to underwriters
         with respect to the financial statements and certain financial
         information of the Company contained in the Registration Statement and
         the Prospectus.

         In the event that the letters to be delivered referred to above set
forth any such changes, decreases or increases, it shall be a further condition
to the obligations of the Underwriters that the Underwriters shall have
determined, after discussions with officers of Company responsible for financial
and accounting matters and with Deloitte & Touche, LLP that such changes,
decreases or increases as are set forth in such letters do not reflect a
material adverse change in the total assets, shareholders' equity or long-term
debt of Company as compared with the amounts shown in the latest balance sheets
of Company included in the Final Prospectus, or a material 



                                       25
<PAGE>   26

adverse change in revenues or net income of Company, in each case as compared
with the corresponding period of the prior year.

                  (f) There shall have been furnished to the Representatives a
         certificate, dated the Closing Date and addressed to you, signed by the
         Chief Executive Officer and Chief Financial Officer of the Company, to
         the effect that:

                           (i)   the representations and warranties of the 
                  Company in Section 1 of this Agreement are true and correct,
                  as if made at and as of the Closing Date, and the Company has
                  complied with all the agreements and satisfied all the
                  conditions on its part to be performed or satisfied at or
                  prior to the Closing Date;

                           (ii)  no stop order suspending the effectiveness of
                  the Registration Statement has been issued, and no proceedings
                  for that purpose have been initiated or are pending, or to
                  their knowledge, threatened under the Securities Act;

                           (iii)  they have carefully examined the Registration
                  Statement, the Effective Prospectus and the Final Prospectus,
                  and any amendments or supplements thereto, and such documents
                  do not include any untrue statement of a material fact or omit
                  to state any material fact required to be stated therein or
                  necessary to make the statements therein not misleading in
                  light of the circumstances under which they were made; and

                           (iv)   since the effective date of the Registration
                  Statement, there has occurred no event required to be set
                  forth in an amendment or supplement to the Registration
                  Statement, the Effective Prospectus or the Final Prospectus
                  which has not been so set forth.

                  (g) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Final Prospectus, and
         except as stated therein, the Company has not sustained any material
         loss or interference with its business or properties from fire, flood,
         hurricane, accident or other calamity, whether or not covered by
         insurance, or from any 



                                       26
<PAGE>   27

         labor dispute or any court or governmental action, order or decree, or
         become a party to or the subject of any litigation which is material to
         the Company, nor shall there have been any material adverse change, or
         any development involving a prospective material adverse change, in the
         business, properties, key personnel, capitalization, prospects, net
         worth, results of operations or condition (financial or other) of the
         Company, which loss, interference, litigation or change, in the
         Representatives' reasonable judgment shall render it inadvisable to
         commence or continue the offering of the Shares at the offering price
         to the public set forth on the cover page of the Prospectus or to
         proceed with the delivery of the Shares.

                  (h) The Shares shall be listed on the Nasdaq National Market.

                  (i) The Representatives shall have received the Lockup
         Agreements.

         All such opinions, certificates, letters and documents delivered
pursuant to this Agreement will comply with the provisions hereof only if they
are reasonably satisfactory to the Representatives and their counsel. The
Company shall furnish to the Representatives such conformed copies of such
opinions, certificates, letters and documents in such quantities as the
Representatives shall reasonably request.

         The respective obligations of the Underwriters to purchase and pay for
the Option Shares shall be subject, in their discretion, to the conditions of
this Section 6, except that all references to the "Closing Date" shall be deemed
to refer to the Option Closing Date, if it shall be a date other than the
Closing Date.

         7. Condition of the Company's Obligations. The obligations hereunder
of the Company are subject to the condition set forth in Section 6(a) hereof.

         8. Indemnification and Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
         Underwriter, and each person, if any, who controls any Underwriter
         within the meaning of the Securities Act, against any losses, claims,
         damages or liabilities to which such Underwriter or controlling person
         may become subject under the Securities Act or otherwise, insofar as
         such losses, claims, damages or liabilities (or actions in respect
         thereof) arise out of or are based in whole or in part upon: (i) any
         inaccuracy in the representations and warranties of the Company
         contained herein; (ii) any failure of the Company to perform its
         obligations hereunder or under law; (iii) any untrue statement or
         alleged untrue statement of any material fact contained in (A) the
         Registration Statement, any Preliminary Prospectus, the Effective
         Prospectus or Final Prospectus, or any amendment or supplement thereto,



                                       27
<PAGE>   28

         or (B) in any Blue Sky application or other written information 
         furnished by the Company filed in any state or other jurisdiction in
         order to qualify any or all of the Shares under the securities laws
         thereof (a "Blue Sky Application"); (iv) or the omission or alleged
         omission to state in the Registration Statement, any Preliminary
         Prospectus, the Effective Prospectus or Final Prospectus or any
         amendment or supplement thereto, or Blue Sky Application a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading; or (v) any act or failure to act or any alleged
         act or failure to act by any Underwriter in connection with, or
         relating in any manner to, the Shares or the offering contemplated
         hereby, and which is included as part of or referred to in any loss,
         claim, damage, liability or action arising out of or based upon matters
         covered by clause (i), (ii), (iii) or (iv) above (provided that the
         Company shall not be liable under this clause (v) to the extent that it
         is determined in a final judgment by a court of competent jurisdiction
         that such loss, claim, damage, liability or action resulted directly
         from any such acts or failures to act undertaken or omitted to be taken
         by such Underwriter through its gross negligence or willful
         misconduct); and will reimburse each Underwriter and each such
         controlling person for any legal or other expenses reasonably incurred
         by such Underwriter or such controlling person in connection with
         investigating or defending any such loss, claim, damage, liability or
         action as such expenses are incurred; provided, however, that the
         Company will not be liable in any such case to the extent that any such
         loss, claim, damage, or liability arises out of or is based upon any
         untrue statement or alleged untrue statement or omission or alleged
         omission made in the Registration Statement, the Preliminary
         Prospectus, the Effective Prospectus or Final Prospectus, or any
         amendment or supplement thereto, or any Blue Sky Application in
         reliance upon and in conformity with written information furnished to
         the Company by any Underwriter specifically for use therein (it being
         understood that the only information so provided is the information
         included in the last paragraph on the cover page and in the third,
         fourth, fifth and eighth paragraphs under the caption "Underwriting" in
         any Preliminary Prospectus and the Final Prospectus and the Effective
         Prospectus).

<PAGE>   29

         
                  (b) Each Underwriter, will indemnify and hold harmless the
         Company, each of its directors, each of the Company's officers who
         signed the Registration Statement and each person, if any, who controls
         the Company within the meaning of the Securities Act against any
         losses, claims, damages or liabilities to which the Company or any
         such director, officer or controlling person may become subject, under
         the Securities Act or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions in respect thereof) arise out of or
         are based upon any untrue statement or alleged untrue statement of any
         material fact contained in the Registration Statement, any Preliminary
         Prospectus, the Effective Prospectus or Final Prospectus, or any
         amendment or supplement thereto, or any Blue Sky Application, or arise
         out of or are based upon the omission or the alleged omission to state
         in the Registration Statement, any Preliminary Prospectus, the
         Effective Prospectus or Final Prospectus, or any amendment or
         supplement thereto, or any Blue Sky Application a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, in each case to the extent, but only to the
         extent, that such untrue statement or alleged untrue statement or
         omission or alleged omission was made in reliance upon and in
         conformity with written information furnished to the Company by any
         Underwriter specifically for use therein (it being understood that the
         only information so provided is the information included in the last
         paragraph on the cover page and in the third, fourth, fifth and eighth
         paragraphs under the caption "Underwriting" in any Preliminary
         Prospectus and in the Effective Prospectus and the Final Prospectus).

<PAGE>   30

                  (c) Promptly after receipt by an indemnified party under this
         Section 8 of notice of the commencement of any action, including
         governmental proceedings, such indemnified party will, if a claim in
         respect thereof is to be made against the indemnifying party under this
         Section 8 notify the indemnifying party of the commencement thereof;
         but the omission so to notify the indemnifying party will not relieve
         it from any liability which it may have to any indemnified party
         hereunder unless the indemnifying party has been materially prejudiced
         thereby and in any event shall not relieve it from liability otherwise
         than under this Section 8. In case any such action is brought against
         any indemnified party, and it notifies the indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate therein, and to the extent that it may wish, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof, with counsel reasonably satisfactory to such indemnified
         party; and after notice from the indemnifying party to such indemnified
         party of its election so to assume the defense thereof, the
         indemnifying party will not be liable to such indemnified party under
         this Section 8 for any legal or other expenses subsequently incurred by
         such indemnified party in connection with the defense thereof other
         than reasonable costs of investigation except that the indemnified
         party shall have the right to employ separate counsel if, in the
         indemnified party's reasonable judgment, it is advisable for the
         indemnified party to be represented by separate counsel, and in that
         event the fees and expenses of separate counsel shall be paid by the
         indemnifying party.

                  (d) In order to provide for just and equitable contribution in
         circumstances in which the indemnity agreement provided for in the
         preceding part of this Section 8 is for any reason held to be
         unavailable to the Underwriters or the Company or is insufficient to
         hold harmless an indemnified party, then the Company shall contribute
         to the damages paid by the Underwriters, and the Underwriters shall
         contribute to the damages paid by the Company; provided, however, that
         no person guilty of fraudulent misrepresentation (within the meaning of
         Section 11(f)) of the Securities Act) shall be entitled to contribution
         from any person who was not guilty of such fraudulent
         misrepresentation. The amount of such contribution shall (i) be in such
         proportion as shall be appropriate to reflect the relative benefits
         received by the Company on the one hand and the Underwriters on the
         other from the offering of the Shares or (ii) if the allocation
         provided by clause (i) above is not permitted by applicable law, be in
         such proportion as is appropriate to reflect not only the relative
         benefits referred to in clause (i) above but also the relative fault of
         the Company on the one hand and the Underwriters on the other with
         respect to the statements or omissions which resulted in such loss,
         claim, damage or liability, or action in respect thereof, as well as
         any other relevant equitable considerations. The relative benefits
         received by the Company on the one hand and


                                       30
<PAGE>   31

         the Underwriters on the other with respect to such offering shall be
         deemed to be in the same proportion as the total net proceeds from the
         offering of the Shares purchased under this Agreement (before deducting
         expenses) received by the Company, in the case of the Company, and the
         total underwriting discounts and commissions received by the
         Underwriters with respect to the Shares purchased under this Agreement,
         in the case of the Underwriters, bear to the total gross proceeds from
         the offering of the Shares under this Agreement, in each case as set
         forth in the Prospectus. The relative fault shall be determined by
         reference to whether the untrue or alleged untrue statement of a
         material fact or omission or alleged omission to state a material fact
         relates to information supplied by the Company or the Underwriters, the
         intent of the parties and their relative knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The Company and the Underwriters agree that it would not be
         equitable if the amount of such contribution were determined by pro
         rata or per capita allocation (even if the Underwriters were treated as
         one entity for such purpose). Notwithstanding the foregoing, no
         Underwriter or person controlling such Underwriter shall be obligated
         to make contribution hereunder which in the aggregate exceeds the
         underwriting discount applicable to the Shares purchased by such
         Underwriter under this Agreement, less the aggregate amount of any
         damages which such Underwriter and its controlling persons have
         otherwise been required to pay in respect of the same or any similar
         claim. The Underwriters' obligations to contribute hereunder are
         several in proportion to their respective obligations and not joint.
         For purposes of this Section, each person, if any, who controls an
         Underwriter within the meaning of Section 15 of the Securities Act
         shall have the same rights to contribution as such Underwriters, and
         each director of the Company, each officer of the Company who signed
         the Registration Statement, and each person, if any, who controls the
         Company within the meaning of Section 15 of the Securities Act shall
         have the same rights to contribution as the Company, as the case 
         may be.

                  (e) No indemnifying party shall, without the prior written
         consent of the indemnified party, effect any settlement of any pending
         or threatened action, suit or proceeding in respect of which any
         indemnified party is a party or is (or would be, if a claim were to be
         made against such indemnified party) entitled to indemnity hereunder,
         unless such settlement includes an unconditional release of such
         indemnified party from all liability on claims that are the subject
         matter of such action, suit or proceeding.



                                       31

         9. Default of Underwriters. If any Underwriter defaults in its
obligation to purchase Shares hereunder and if the total number of Shares which
such defaulting Underwriter agreed but failed to purchase is ten percent or less
of the total number of Shares to be sold hereunder, the non-defaulting
Underwriters shall be obligated severally to purchase (in the respective
proportions which the number of Shares set forth opposite the name of each
non-defaulting Underwriter in Schedule I hereto bears to the total number of
Shares set forth opposite the names of all the non-defaulting Underwriters), the
Shares which such defaulting Underwriter or Underwriters agreed but failed to
purchase. If any Underwriter so defaults and the total number of Shares with
respect to which such default or defaults occur is more than ten percent of the
total number of Shares to be sold hereunder, and arrangements satisfactory to
the other Underwriters and the Company for the purchase of such Shares by other
persons (who may include the non-defaulting Underwriters) are not made within 36
hours after such default, this Agreement, insofar as it relates to the sale of
the Shares, will terminate without liability on the part of the non-defaulting
Underwriters or the Company except for (i) the provisions of Section 8 hereof,
and (ii) the expenses to be paid or reimbursed by the Company pursuant to
Section 5. As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 9. Nothing herein shall
relieve a defaulting Underwriter from liability for its default.

         10. Survival Clause. The respective representations, warranties,
agreements, covenants, indemnities and other statements of the Company or its
officers and the Underwriters set forth in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement shall remain in full
force and effect, regardless of (a) any investigation made by or on behalf of
the Company, any of its officers or its directors, any Underwriter or any 



                                       32
<PAGE>   33

controlling person, (b) any termination of this Agreement and (c) delivery of
and payment for the Shares.

         11. Effective Date. This Agreement shall become effective at whichever
of the following times shall first occur: (i) at 11:30 am Washington D.C. time,
on the next full business day following the date in which the Registration
Statement becomes effective or (ii) at such time after the Registration
Statement has become effective as the Representatives shall release the Firm
Shares for sale to the public; provided, however, that the provisions of
Sections 5,8,10, and 11 hereof shall at all times be effective. For purposes of
this Section 11, the Firm Shares shall be deemed to have been so released upon
the release by the Representatives for publication, at any time after the
Registration Statement has become effective, of any newspaper advertisement
relating to the Firm Shares or upon the release by the Representatives of
telegrams offering the Firm Shares for sale to securities dealers, whichever may
occur first.

         12. Termination.

                  (a) The Company's obligations under this Agreement may be
         terminated by the Company by notice to the Representatives (i) at any

         Re:     REGISTRATION STATEMENT ON FORM S-1 (File No. 333-50813)

Dear Ladies and Gentlemen:

         We have acted as your counsel in connection with the preparation of a
Registration Statement on Form S-1 (the "Registration Statement") filed by you
with the Securities and Exchange Commission, covering 4,255,000 shares of Class
A Common Stock, no par value (the "Class A Common Stock"), of AmSurg Corp., a
Tennessee corporation (the "Company"), to be offered by the Company.

         In connection with this opinion, we have examined and relied upon such
records, documents and other instruments as in our judgment are necessary or
appropriate in order to express the opinions hereinafter set forth and have
assumed the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, and the conformity to original documents of all
documents submitted to us as certified or photostatic copies.

         Based upon the foregoing and such other matters as we have deemed
relevant, we are of the opinion that the shares of Class A Common Stock to be
offered by the Company, when and as described in the Registration Statement 
(after the Registration Statement is declared effective), will be validly
issued, fully paid and nonassessable.

         We hereby consent to the reference to our law firm in the Registration
Statement under the caption "Legal Matters" and to the use of this opinion as
an exhibit to the Registration Statement.


                                                      Sincerely,






                                                      /s/ Bass, Berry & Sims PLC

         an Applicable Interest Rate on the Borrowing Request, then it shall be
         conclusively presumed that the Borrower has elected the Base Rate.

                  (b) At any time that the outstanding principal balance of an
         Advance bears interest at the Base Rate, the Borrower may elect upon
         two (2) Business Days prior written notice and delivery to Agent of a
         Notice of Interest Rate Election to convert the Applicable Interest
         Rate to a LIBOR Based Rate.

                  (c) Once the Borrower has selected the LIBOR Based Rate, such
         rate shall remain applicable until the expiration of the then
         applicable LIBOR Based Rate Period. Two (2) Business Days prior to the
         expiration of any applicable LIBOR Based Rate Period, the Borrower
         shall deliver to Agent a Notice of Interest Rate Election. Should the
         Borrower fail to deliver such Notice of Interest Rate Election in a
         timely manner, then it shall be conclusively presumed that the Borrower
         has selected the Base Rate as the Applicable Interest Rate.

                  (d) At any time, no more than six (6) different LIBOR Based
         Rate Periods may be applicable to all Advances.

                  (e) The Applicable Interest Rate shall be computed on the
         basis of a year of 360 days for the actual number of days elapsed.

                  (f) The following provisions shall apply at any time that the
         LIBOR Based Rate is applicable:

                           (i) Increased Cost. If, as a result of any change in
                  applicable law, regulation, treaty or directive, in the
                  interpretation or application thereof or compliance by Agent
                  or any of the Lenders with any request or directive (whether
                  or not having the force of law) from any court or governmental
                  authority, agency or instrumentality:

                                     (A) the basis of taxation of payments to
                           any of the Lenders of the principal of or interest on
                           any loan on which a LIBOR Based Rate is applicable
                           (other than taxes imposed on the overall net income
                           of either of the Lenders) is changed;





                                       12

                                     (B) any reserve, special deposit or similar
                           requirements against assets of, deposits with or for
                           the account of, or credit extended by, Agent or any
                           of the Lenders are imposed, modified or deemed
                           applicable; or

                                     (C) any other condition affecting this
                           Agreement or the LIBOR Based Rate is imposed on Agent
                           or any of the Lenders or the London eurodollar
                           market;

                  and Agent or any of the Lenders determines that, by reason
                  thereof, the actual out-of-pocket cost to Agent or any of the
                  Lenders of offering, making, or maintaining the LIBOR Based
                  Rate is increased, or the amount of any sum receivable by
                  Agent or any of the Lenders hereunder in respect of any of the
                  LIBOR Based Rate is reduced;

                  then, Borrower shall pay to Agent or such of the Lenders as
                  designated by Agent upon demand (which demand shall be
                  accompanied by a statement setting forth the basis for the
                  calculation thereof but only to the extent not theretofore
                  provided to Borrower) such additional amount or amounts as
                  will compensate Agent or any of the Lenders for such
                  additional cost or reduction. Determinations by the Agent for
                  purpose of this section of the additional amounts required to
                  compensate Agent or any of the Lenders in respect of the
                  foregoing shall be conclusive, absent demonstrable error.

                           (ii) Eurodollar Deposits Unavailable or Interest Rate
                  Unascertainable. In the event that the Agent shall have
                  reasonably determined (which determination shall be conclusive
                  and binding on the parties hereto, absent demonstrable error)
                  that deposits of the necessary amount for the relevant LIBOR
                  Based Rate Period are not available to Agent or any of the
                  Lenders in the London Eurodollar market or that, by reason of
                  circumstances affecting such market, adequate and reasonable
                  means do not exist for ascertaining the LIBOR Based Rate
                  applicable to such period or term, as the case may be, or that
                  the application or use of the LIBOR Based Rate would be
                  impracticable as a result of a contingency occurring after the
                  Closing Date that materially and adversely affects the London
                  interbank market, then Agent shall promptly give notice of
                  such determination to Borrower and (i) any notice of new LIBOR
                  Based Rate selection previously given by Borrower and not yet
                  converted shall be deemed a selection of the Base Rate and
                  (ii) the existing LIBOR Based Rate shall be converted to the
                  Base Rate on the last day of the then current LIBOR Based Rate
                  Period with respect thereof.

                           (iii) Changes in Law Rendering the LIBOR Based Rate
                  Unlawful. If at any time due to any new law, treaty or
                  regulation, or any interpretation thereof by any governmental
                  or other regulatory authority charged with the administration
                  thereof, or for any other reason arising subsequent to the
                  date hereof, it shall become unlawful for Agent or any of the
                  Lenders to offer, charge or collect




                                       13
<PAGE>   18

                  interest based on the LIBOR Based Rate, the obligation of
                  Agent or such of the Lenders to provide the LIBOR Based Rate
                  shall, upon the happening of such event, forthwith be
                  suspended for the duration of such illegality. Upon the
                  happening of such event, Agent or any of the Lenders shall
                  notify Borrower thereof in writing, and Borrower, at its
                  election, shall, on the earlier of (i) the last day of the
                  then current LIBOR Based Rate Period or (ii) if required by
                  such law, regulation or interpretation, on such date as shall
                  be specified in such notice, either convert the unlawful LIBOR
                  Based Rate to the Base Rate or repay such of the Revolving
                  Credit Notes, without penalty, to Agent or any of the Lenders,
                  as designated by Agent, in full, together with all interest
                  accrued thereon.

                           (iv) Other Changes Rendering Use of LIBOR Based Rate
                  a Severe Hardship. In the event that on any date after the
                  Closing Date Agent or any of the Lenders shall reasonably
                  determine (which determination shall be conclusive and binding
                  on the parties hereto, absent demonstrable error) that the use
                  and/or application of the LIBOR Based Rate will cause the
                  Agent or any of the Lenders severe hardship as a result of a
                  contingency occurring after the date of this Agreement; then,
                  and in any such event, the Agent and the affected Lenders
                  shall give telephonic notice (immediately confirmed in
                  writing) to the Borrower of such determination, and the
                  obligation of the Agent and such of the affected Lenders to
                  offer or permit the selection of the LIBOR Based Rate shall be
                  terminated at the earlier of the end of the then current LIBOR
                  Based Rate Period, and upon such date the Borrower, at its
                  option shall either repay such Revolving Credit Note, without
                  penalty, together with all interest accrued thereon, or
                  convert such Revolving Credit Note to the Base Rate.

                           (v) Adjustments to Rate to Cover Additional Cost. It
                  is the intention of the parties that the LIBOR Based Rate
                  shall accurately reflect the cost to the Lenders of
                  maintaining loans at the LIBOR Based Rate during the
                  applicable LIBOR Based Rate Period.
                  Accordingly:

                                     (i) if by reason of any change after the
                           date hereof in any applicable law or governmental
                           rule, regulation or order (or any interpretation
                           thereof and including the introduction of any new law
                           or governmental rule, regulation or order), including
                           any change in the LIBOR reserve requirement, the cost
                           to either of the Lenders of maintaining loans at the
                           LIBOR Based Rate or funding the same by means of a
                           London interbank market time deposit, as the case may
                           be, shall increase, the LIBOR Based Rate then charged
                           by any of the Lenders shall be adjusted as necessary
                           to reflect such change in cost to any of the Lenders,
                           effective as of the date on which such change in any
                           applicable law, governmental rule, regulation or
                           order becomes effective.

                                     (ii) if the Agent shall have determined
                           that the adoption after the Closing Date of any law,
                           rule, regulation or guideline regarding capital
                           adequacy, or any change in any of the foregoing or in
                           the interpretation or administration of any of the
                           foregoing by any governmental authority or agency,
                           central bank or comparable agency charged with the
                           interpretation or administration thereof, or
                           compliance by any of the Lenders (or any lending
                           office of any of the Lenders) or any of the Lenders'
                           holding company with any request or directive
                           regarding capital adequacy (whether or not having the
                           force of law) of any such governmental authority or
                           agency, central bank or comparable agency, has or
                           would have the effect of reducing the rate of return
                           on any of the Lenders' capital or on the capital of
                           any of the Lenders' holding company, as a consequence
                           of the Lenders' obligations under this Agreement or
                           the Advances made by any of the Lenders pursuant
                           hereto to a level below that which any of the Lenders
                           or either of the Lenders' holding company could have
                           achieved but for such adoption, change or compliance
                           (taking into consideration the Lenders' guidelines
                           with respect to capital adequacy) by an amount deemed
                           by any of the Lenders to be material, then from time
                           to time the Borrower shall pay to the Agent for
                           delivery to the Lenders such additional amount or
                           amounts as will compensate such of the Lenders or
                           such of the Lenders' holding company for any such
                           reduction suffered.

                  (g) Borrower may prepay the principal amount evidenced by any
         Advance at any time that the Applicable Interest Rate is the Base Rate.
         Except as provided specifically in Section 2.06(f)(i), (iii) and (iv),
         Borrower may not prepay any Advance so long as the Applicable Interest
         Rate is the LIBOR Based Rate, except at the maturity of any applicable
         LIBOR Based Rate Period.

         Section 2.07 Participation. The Lenders shall have the right to enter
into one or more participation agreements with affiliates of Lenders, but not
further or otherwise.

         Section 2.08 Use of Proceeds. Proceeds of the Revolving Credit Notes
will be used to: (i) permit the issuance of Letters of Credit, (ii) enable the
Borrower to make (x) loans to Partnerships or LLC's for the construction and
renovation of Projects and/or (y) Acquisitions and Physician Practice
Acquisitions, or (iii) for working capital.

         Section 2.09 Payments to Principal Office; Debit Authority. Each
payment under the Revolving Credit Notes (including any permitted prepayment and
payment of interest) shall be made to Agent at its Principal Office for the
account of Lenders in U.S. dollars and in immediately available funds before
11:00 a.m. Nashville time on the date such payment is due.

         Section 2.10 Letters of Credit. (a) Provided no Event of Default or
Default Condition exists and subject to the terms and conditions of the Loan
Documents, the Lenders have agreed



                                       15
<PAGE>   20

that the Agent on behalf of the Lenders will issue to third party beneficiaries
on the Borrower's account standby Letters of Credit.

                  (b) In connection with the issuance of each Letter of Credit,
         the Borrower shall complete a Letter of Credit Application Agreement
         and such other documentation, in form and substance as required by the
         Agent.

                  (c) In connection with each Letter of Credit, the Borrower
         shall pay to the Agent a Letter of Credit Fee to be apportioned and
         paid by Agent to each of the Lenders pursuant to the Pro Rata Share of
         each Lender.

                  (d) In connection with each Letter of Credit, the Borrower
         shall pay to the Agent administrative and documentation fees in such
         amount as established by Agent from time to time, which administrative
         and documentation fees shall be retained by Agent and shall not be
         apportioned among the Lenders.

                  (e) The issuance by the Agent of a Letter of Credit shall
         reduce the Borrower's ability to receive Advances under the Revolving
         Credit Notes by an amount equal to the face amount of the Letter of
         Credit for so long as the Letter of Credit remains outstanding.

                  (f) In the event that the Agent is required to pay to any
         Person the proceeds (partially or in full) of a Letter of Credit, the
         Borrower agrees to pay to the Agent immediately on demand by the Agent,
         an amount equal to the proceeds paid by the Agent to such Person, plus
         interest from the date of such payment at an amount equal to the Base
         Rate.

                  (g) Letters of Credit issued by the Agent shall not be issued
         for a time period in excess of twelve months.

                  (h) The Agent shall have no obligation to issue Letters of
         Credit on or after January 10, 2000.

                  (i) The Lenders shall participate in all Letters of Credit
         issued by the Agent. Each Lender, upon the issuance of a Letter of
         Credit by the Agent, shall be deemed to have purchased without recourse
         a risk participation from the Agent in such Letter of Credit and the
         obligations arising thereunder, in each case in an amount equal to its
         Pro Rata Share of all obligations under such Letter of Credit and shall
         absolutely, unconditionally, and irrevocably assume, as primary obligor
         and not as a surety, and be obligated to pay to the Agent therefor and
         discharge when due, its Pro Rata Share of all obligations arising under
         such Letter of Credit. Without limiting the scope and nature of each
         Lender's participation in any Letter of Credit, to the extent that the
         Agent has not been reimbursed as required hereunder or under any such
         Letter of Credit, each such Lender shall pay to the Agent its Pro Rata
         Share of such unreimbursed drawing in same



                                       16
<PAGE>   21

         day funds on the day of notification by the Agent of an unreimbursed
         drawing. The obligation of each Lender to so reimburse the Agent shall
         be absolute and unconditional and shall not be affected by the
         occurrence of a Default Condition or an Event of Default or any other
         occurrence or event.

         Section 2.11 Right of Offset, Etc. The Borrower hereby agrees that, in
addition to (and without limitation of) any right of set-off, banker's lien or
counterclaim the Agent or the Lenders may otherwise have, the Agent and the
Lenders shall be entitled, at their option, to offset balances held by any of
Agent or Lenders at any of their offices against any principal of or interest on
the Obligations hereunder which is not paid within fifteen (15) days after such
payment is due, and in the event Agent or any of the Lenders does offset against
such balances, it shall promptly notify the Borrower, provided that its failure
to give such notice shall not affect the validity thereof.

         Section 2.12 Usury. The parties to this Agreement intend to conform
strictly to applicable usury laws as presently in effect. Accordingly, if the
transactions contemplated hereby would be usurious under applicable law
(including the laws of the United States of America and the State of Tennessee),
then, in that event, notwithstanding anything to the contrary in any Loan
Document or agreement executed in connection with or as security for the
Obligations, Borrower, Agent, and the Lenders agree as follows: (i) the
aggregate of all consideration that constitutes interest under applicable law
which is contracted for, charged, or received under any of the Loan Documents or
agreements, or otherwise in connection with the Obligations, shall under no
circumstance exceed the maximum lawful rate of interest permitted by applicable
law, and any excess shall be credited on the Obligations by the holder thereof
(or, if the Obligations shall have been paid in full, refunded to Borrower); and
(ii) in the event that the maturity of the Obligations is accelerated by reason
of an election of the holder resulting from any Event of Default under this
Agreement or otherwise, or in the event of any required or permitted prepayment,
then such consideration that constitutes interest may never include more than
the maximum amount of interest permitted by applicable law, and excess interest,
if any, for which this Agreement provides, or otherwise, shall be cancelled
automatically as of the date of such acceleration or prepayment and, if
previously paid, shall be credited on the Obligations (or, if the Obligations
shall have been paid in full, refunded to Borrower).

Article III. Collateral and Guarantees.

         Section 3.01 Collateral. The Indebtedness and Obligations shall be
secured by the following:

                  (a) all Partnership Notes, Partnership Note Collateral, LLC
         Notes, and LLC Note Collateral;

                  (b) all deposit accounts, monies, and items of value of
         Borrower now or hereafter placed in the possession of Agent or any of
         the Lenders;



                                       17
<PAGE>   22

                  (c) all securities pledged to Agent on behalf of Lenders

corporations duly organized, and validly existing, and in good standing under
the laws of the states of their respective incorporation, and the Borrower and
each Subsidiary are duly qualified as a foreign corporation in all jurisdictions
in which the Property owned or the business transacted by each of them makes

general partner in a Partnership or member in an LLC.

         Each Partnership and LLC that has executed LLC Notes or Partnership
Notes, as applicable, as of the date hereof is duly formed and validly existing

Properties of Borrower, other than those contemplated by the Loan Documents.

provisions contained in any Loan Document for any reason shall be held invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or

Lenders under each Loan Document shall be cumulative, and the exercise or
partial exercise of any such right or remedy shall not preclude the exercise of

                  similar credit facilities for its own account.

                           (ii) The Agent shall not, without the consent of the

                           Loan Document or to collect the Indebtedness
                           described herein.

                           (iii) The Agent shall not, without the consent of
                           all of the Lenders, take any of the following 
                           actions:

                                     (A) extend the maturity of any payment of
                           principal of or interest on the Indebtedness
                           described herein;

                                     (B) reduce any fees paid to or for the
                           benefit of Lenders under the Loan Agreement;

                                     (C) reduce the rate of interest charged on
                           the Indebtedness described herein;

                                     (E) postpone any date fixed for the
                           payment in respect of principal of, or interest on
                           the Indebtedness described herein, or any fees
                           hereunder;

                                     (F) modify the definition of Majority
                           Lenders; or

                                     (G) modify this Section 11.02(b)(iii).

                  (c)      The Agent, upon its receipt of actual notice 
         thereof, shall notify the Lenders of: (i) each proposed action that
         would require the consent of the Lenders as set forth herein, or (ii)
         any action proposed to be taken by the Agent in the administration of
         the Loans and Loan Documents not in the ordinary course of business;
         provided that any failure of the Agent to give the Lenders any such
         notice shall not alone be the basis for any liability of the Agent to
         the Lenders except for the Agent's gross negligence or willful
         misconduct.

                  (d)    The Lenders agree that the Agent shall incur no 
         liability under or in respect of this Agreement with respect to
         anything which it may do or refrain from doing in the



                                       42
<PAGE>   47

         reasonable exercise of its judgment or which may seem to it to be
         necessary or desirable in the circumstances, except for its gross
         negligence or willful misconduct. Agent shall incur no liability to
         any of the Lenders for giving consent on behalf of the Lenders when
         under the terms of this Agreement consent may not be unreasonably
         withheld.

                  (e)    The Agent shall not be liable to the Lenders or to any
         Lender in acting or refraining from acting under this Agreement or any
         other Loan Document in accordance with the instructions of the
         Majority Lenders or all of the Lenders, where expressly required by
         this Agreement, and any action taken or failure to act pursuant to
         such instructions shall be binding on all Lenders. In each
         circumstance where any consent of or direction from the Majority
         Lenders or all of the Lenders is required or requested by Agent, the
         Agent shall send to the Lenders a notice setting forth a description
         in reasonable detail of the matter as to which consent or direction is
         requested and the Agent's proposed course of action with respect
         thereto. In the event the Agent shall not have received a response
         from any Lender within five (5) Business Days after Agent sends such
         notice, such Lender shall be deemed to have agreed to the course of
         action proposed by the Agent.

         Section 11.03 Agent's Duties Limited; No Fiduciary Duty. The Lenders
agree that the Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and the other Loan Documents. The Lenders
agree that none of the Agent nor any of its respective officers, directors,
employees or agents shall be liable for any action taken or omitted by it as
such hereunder or in connection herewith, unless caused by its or their gross
negligence or willful misconduct. The Agent shall not have by reason of this
Agreement a fiduciary relationship to or in respect of any of the Lenders, and
nothing in this Agreement, express or implied, is intended to or shall be so
construed as to impose upon the Agent any obligations in respect of this
Agreement or the other Loan Documents except as expressly set forth herein.

         SECTION 11.04 NO RELIANCE ON THE AGENT. (a) EACH OF THE LENDERS
REPRESENTS AND WARRANTS TO THE AGENT AND THE OTHER LENDERS THAT INDEPENDENTLY
AND WITHOUT RELIANCE UPON THE AGENT, EACH OF THE LENDERS, TO THE EXTENT IT
DEEMS APPROPRIATE, HAS MADE AND SHALL CONTINUE TO MAKE (I) ITS OWN INDEPENDENT
INVESTIGATION OF THE FINANCIAL CONDITION AND AFFAIRS OF THE BORROWER AND THE
GUARANTORS IN CONNECTION WITH THE TAKING OR NOT TAKING OF ANY ACTION IN
CONNECTION HEREWITH, AND (II) ITS OWN APPRAISAL OF THE CREDIT WORTHINESS OF THE
BORROWER AND THE GUARANTORS, AND EACH OF THE LENDERS FURTHER AGREES THAT,
EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, THE AGENT SHALL HAVE NO DUTY OR
RESPONSIBILITY, EITHER INITIALLY OR ON A CONTINUING BASIS, TO PROVIDE ANY OF
THE LENDERS WITH ANY CREDIT OR OTHER INFORMATION WITH RESPECT THERETO, WHETHER
COMING INTO ITS POSSESSION BEFORE THE MAKING OF THE LOANS OR AT ANY TIME OR
TIMES THEREAFTER. AS LONG AS ANY OF THE LOANS ARE OUTSTANDING AND/OR ANY AMOUNT
IS AVAILABLE TO BE REQUESTED OR BORROWED HEREUNDER, OR THIS AGREEMENT AND THE
LOAN DOCUMENTS



                                       43
<PAGE>   48

HAVE NOT BEEN CANCELLED AND TERMINATED, EACH OF THE LENDERS SHALL CONTINUE TO
MAKE ITS OWN INDEPENDENT EVALUATION OF THE FINANCIAL CONDITION AND AFFAIRS OF
THE BORROWERS AND THE GUARANTORS.

                  (b)    The Agent shall not be responsible to any of the 
         Lenders for any recitals, statements, information, representations or
         warranties herein or in any document, certificate or other writing
         delivered in connection herewith or for the execution, effectiveness,
         genuineness, validity, enforceability, collectability, priority or
         sufficiency of this Agreement, the Revolving Credit Notes, the
         Guarantees, the other Loan Documents, or any other documents
         contemplated hereby or thereby, or the financial condition of the
         Borrower or the Guarantors, or be required to make any inquiry
         concerning either the performance or observance of any of the terms,
         provisions or conditions of this Agreement, the Revolving Credit
         Notes, the Guarantees, the other Loan Documents or the other documents
         contemplated hereby or thereby, or the financial condition of the
         Borrower or the Guarantors, or the existence or possible existence of
         any Default Condition or Event of Default.

         Section 11.05 Certain Rights of Agent. The Lenders agree that if the
Agent shall request instructions from the Majority Lenders (or all of the
Lenders where unanimity is expressly required under the terms of this
Agreement) with respect to any action or actions (including the failure to act)
in connection with this Agreement, the Agent shall be entitled to refrain from
such act or taking such act, unless and until the Agent shall have received
instructions from the Majority Lenders (or all of the Lenders where unanimity
is expressly required under the terms of this Agreement); and the Agent shall
not incur liability to any Person by reason of so refraining. Without limiting
the foregoing, none of the Lenders shall have any right of action whatsoever
against the Agent as a result of the Agent acting or refraining from acting
hereunder in accordance with the instructions of the Majority Lenders (or, with
regard to acts for which the consent of all of the Lenders is expressly
required under the terms of this Agreement, in accordance with the instructions
of all of the Lenders).

         Section 11.06 Reliance by Agent. The Lenders agree that the Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
note, writing, resolution, notice, statement, certificate, telex, teletype or
telecopier message, cablegram, radiogram, order or other documentary,
teletransmission or telephone message reasonably believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person. The
Lenders agree that the Agent may consult with legal counsel (including counsel
for any of the Lenders), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken by it in good faith in accordance with the advice of such counsel,
accountants or experts.

         Section 11.07 Indemnification of Agent. To the extent the Agent is not
reimbursed and indemnified by the Borrower, each of the Lenders will reimburse
and indemnify the Agent, ratably according to their respective Pro Rata Share,
for, from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including fees of
experts, consultants and counsel and disbursements) or disbursements of any
kind or nature



                                       44
<PAGE>   49

whatsoever that may be imposed on, incurred by or asserted against the Agent in
performing its duties hereunder, in any way relating to or arising out of this
Agreement or the other Loan Documents; provided that none of the Lenders shall
be liable to the Agent for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful
misconduct. The obligations and indemnifications arising under this Section
11.07 shall survive termination of this Agreement, repayment of the Loans and
indebtedness arising in connection with the Letters of Credit and expiration of
the Letters of Credit.

         Section 11.08 The Agent in its Individual Capacity. With respect to
its obligation to lend under this Agreement and the Loans made by it, the Agent
shall have the same rights and powers hereunder as any other of the Lenders,
and may exercise the same as though it were not performing the duties of Agent
specified herein; and the terms "Lenders" and "Majority Lenders" or any similar
terms shall, unless the context clearly otherwise indicates, include the Agent
in its individual capacity. The Agent and its affiliates may accept deposits
from, lend money to, and generally engage in any kind of banking, trust,
financial advisory or other business with the Borrower and the Guarantors, and
any affiliate of the Borrower as if it were not performing the duties specified
herein as Agent, and may accept fees and other consideration from the Borrower
for services in connection with this Agreement and otherwise without having to
account for the same to the Lenders.

         Section 11.09 Successor Agent. (a) The Agent may resign at any time by
giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with cause by the Majority Lenders; provided, however, the
Agent may not resign or be removed until (i) a successor Agent has been
appointed and shall have accepted such appointment and (ii) the successor Agent
has assumed all responsibility for issuance of the Letters of Credit and the
successor Agent has assumed in the place and stead of the Agent all existing
liability under outstanding Letters of Credit. The transactions described in
the immediately preceding sentence shall be accomplished pursuant to written
agreements reasonably satisfactory to the Agent and the successor Agent. Upon
any such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Agent. If no successor Agent shall have been so appointed
by the Majority Lenders, and shall have accepted such appointment, within
thirty (30) days after the retiring Agent's giving of notice of resignation or
the Majority Lenders' removal of the retiring Agent, then the retiring Agent
may, on behalf of the Lenders, appoint a successor Agent, which shall be a bank
that maintains an office in the United States, or a commercial bank organized
under the laws of the United States of America or any State thereof, or any
Affiliate of such bank, having a combined capital and surplus of at least
$100,000,000.

                  (b)    Upon the acceptance of any appointment as the Agent
         hereunder by a successor Agent, such successor Agent shall thereupon
         succeed to and become vested with all the rights, powers, privileges
         and duties of the retiring Agent, and the retiring Agent shall be
         discharged from its duties and obligations under this Agreement. After
         any retiring Agent's resignation or removal hereunder as Agent, the
         provisions of this Article XI shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was an Agent under
         this Agreement.



                                       45

         Section 11.10 Notice of Default or Event of Default. In the event that
the Agent or any of the Lenders shall acquire actual knowledge, or shall have
been notified, of any Default Condition or Event of Default (other than through
a notice by one party hereto to all other parties), the Agent or such Lender
shall promptly notify the Agent, and the Agent shall take such action and
assert such rights under this Agreement as the Majority Lenders shall request
in writing, and the Agent shall not be subject to any liability by reason of
its acting pursuant to any such request. If, following notification by Agent to
Lenders, the Majority Lenders (or all of the Lenders if required hereunder)
shall fail to request the Agent to take action or to assert rights under this
Agreement in respect of any Default Condition or Event of Default within five
(5) Business Days after their receipt of the notice of any Default Condition or
Event of Default from the Agent or any Lender, or shall request inconsistent
action with respect to such Default Condition or Event of Default, the Agent
may, but shall not be required to, take such action and assert such rights as
it deems in its discretion to be advisable for the protection of the Lenders.

         Section 11.11 Sharing of Payments, etc. Each of the Lenders agrees
that if it shall, through the exercise of a right of banker's lien, set-off,
counterclaim or otherwise, obtain payment with respect to the Indebtedness
which results in its receiving more than its Pro Rata Share of the aggregate
payments with respect to all of the Indebtedness, then (a) such Lender shall be
deemed to have simultaneously purchased from the other Lender a share in the
Indebtedness so that the amount of the Indebtedness held by each of the Lenders
shall continue to equal their respective Pro Rata Shares, and (b) such other
adjustments shall be made from time to time as shall be equitable to insure
that the Lenders share such payments ratably.

         Section 11.12 Separate Liens on Collateral. Each Lender agrees with
the other Lenders that it will not take or permit to exist any Lien in its
favor on any of the Collateral or other property of any of the Borrowers other
than Liens securing the Indebtedness.

         Section 11.13 Payments Between Agent and Lenders. All payments by the
Agent to any Lender, and all payments by any Lender to the Agent, under the
terms of this Agreement shall be made by wire transfer in immediately available
funds to the receiving party's address specified in or pursuant to Section 9.01
hereof. If the Agent or any of the Lenders shall fail to pay when due any sum
payable to the Agent or any other Lender, such sum shall bear interest until
paid at the interest rate per annum for overnight borrowing by the payee from
the Federal Reserve Bank for the period commencing on the date such payment was
due and ending on, but excluding, the date such payment is made.

         Section 11.14 Independent Agreements. The provisions contained in
Sections 11.01 through 11.10 and Sections 11.12, 11.13, and 11.15 constitute
independent obligations and agreements of the Agent and the Lenders, and the
Borrower shall not be deemed a party thereto or bound thereby or entitled to
any benefit thereunder. The Borrower acknowledges the rights of the Lenders and
the Agent under Section 11.11.

         Section 11.15 Limitation on Lenders. The Borrower agrees and
acknowledges that neither the Agent nor STB shall have liability to the
Borrower for any damages or claim of any kind whatsoever, whether seen or
unforeseen, arising out of or in connection with the failure of NBT



                                       46
<PAGE>   51

to fund through the Agent its Pro Rata Share of any Advance, and that
Borrower's sole recourse for such conduct by NBT shall be to NBT.

         The Borrower agrees and acknowledges that NBT shall not have liability
to the Borrower for any damages or claims of any kind whatsoever, whether seen
or unforeseen, arising out of or in connection with the failure of STB to fund
through the Agent its Pro Rata Share of any Advance, and that Borrower's sole
recourse for such conduct by STB shall be to STB.

               FORM OF AMENDED AND RESTATED REVOLVING CREDIT NOTE

         FOR VALUE RECEIVED, AMSURG CORP., a Tennessee corporation (hereinafter
referred to as "Borrower"), promises and agrees to pay to the order of SUNTRUST
BANK, NASHVILLE, N.A., a national bank (the "Lender") at the Nashville,
Tennessee offices of SunTrust Bank, Nashville, N.A., Agent (the "Agent"), in
lawful money of the United States of America, the principal sum
of_______________ and no/100 Dollars ($_______________ ), or so much thereof as
may be advanced from time to time by the Lender, together with interest on the
unpaid principal balance outstanding from time to time hereon computed from the
date of each advance until maturity at the rate of interest set forth in that
certain Third Amended and Restated Loan Agreement executed among Borrower,
Lender, NationsBank of Tennessee, N.A., and Agent dated May___, 1998, as such
may be amended from time to time (herein referred to as the "Loan Agreement").
Interest for each year shall be computed on the basis of a year of 360 days for
the actual number of days elapsed.

         So long as no default has occurred and is continuing hereunder and so
long as no Event of Default or Default Condition has occurred and is continuing
under the Loan Agreement, and subject to the terms of the Loan Agreement, the
Borrower may borrow hereunder, repay such borrowings, and reborrow hereunder as
provided in the Loan Agreement. Lender shall keep records of all borrowings and
repayments. Draws under this Note shall be evidenced by such documentation as
required by Article II of the Loan Agreement.

         Advances under this Note shall be made pursuant to the procedure
specified in the Loan Agreement.

         This Note shall be repaid as follows:

                  (a) Commencing on the tenth (10th) day of ___,___, and on the
         tenth day of each consecutive month through and including December 10,
         2000, the Borrower shall pay to Lender an amount equal to all then
         accrued interest; and

                  (b) On January 10, 2001, this Note shall mature at which time
         the Borrower shall pay to Lender an amount equal to all outstanding
         principal, plus all then accrued interest.

         This Note is subject to the terms of the Loan Agreement.

         Notwithstanding any provision to the contrary, it is the intent of the
Lender, the Borrower, and all parties liable on this Note, that neither the
Lender nor any subsequent holder shall be entitled to receive, collect, reserve
or apply, as interest, any amount in excess of the maximum
<PAGE>   59

lawful rate of interest permitted to be charged by applicable law or
regulations, as amended or enacted from time to time. In the event the Note
calls for an interest payment that exceeds the maximum lawful rate of interest
then applicable, such interest shall not be received, collected, charged, or
reserved until such time as that interest, together with all other interest
then payable, falls within the then applicable maximum lawful rate of interest.
In the event the Lender, or any subsequent holder, receives any such interest
in excess of the then maximum lawful rate of interest, such amount which would
be excessive interest shall be deemed a partial prepayment of principal and
treated hereunder as such, or, if the principal indebtedness evidenced hereby
is paid in full, any remaining excess funds shall immediately be paid to the
Borrower. In determining whether or not the interest paid or payable, under any
specific contingency, exceeds the maximum lawful rate of interest, the Borrower
and the Lender shall, to the maximum extent permitted under applicable law, (a)
exclude voluntary prepayments and the effects thereof, and (b) amortize,
prorate, allocate, and spread, in equal parts, the total amount of interest
throughout the entire term of the indebtedness; provided that if the
indebtedness is paid in full prior to the end of the full contemplated term
hereof, and if the interest received for the actual period of existence hereof
exceeds the maximum lawful rate of interest, the holder of the Note shall
refund to the Borrower the amount of such excess or credit the amount of such
excess against the principal portion of the indebtedness as of the date it was
received, and, in such event, the Lender shall not be subject to any penalties
provided by any laws for contracting for, charging, reserving, collecting or
receiving interest in excess of the maximum lawful rate of interest.

         Principal and unpaid interest bear interest during the continuance of
any default in payment of principal and interest as herein provided at the
lesser of (i) the Base Rate (as defined in the Loan Agreement) plus 4% per
annum, or the maximum lawful rate of interest permitted by law. In case of
suit, or if this obligation is placed in an attorney's hands for collection, or
to protect the security for its payment, the undersigned will pay all costs of
collection and litigation, including a reasonable attorney's fee.

         In the event that there occurs any breach of any promise made in this
Note and such breach continues for longer than fifteen (15) days, or upon the
occurrence of an Event of Default as defined in the Loan Agreement, then,
during the continuance of any of such events, at the option of the holder, the
entire indebtedness hereby evidenced shall become due, payable and collectible
then or thereafter, without notice, as the holder may elect regardless of the
date of maturity. The holder may waive any default before or after the same has
been declared and restore this Note to full force and effect without impairing
any rights hereunder, such right of waiver being a continuing one.

         The makers, endorsers, guarantors and all parties to this Note and all
who may become liable for same, jointly and severally waive presentment for
payment, protest, notice of protest, notice of nonpayment of this Note, demand
and all legal diligence in enforcing collection, and hereby expressly agree
that the lawful owner or holder of this Note may defer or postpone collection
of the whole or any part thereof, either principal and/or interest, or may
extend or renew the whole or any part thereof, either principal and/or
interest, or may accept additional collateral or security for the payment of
this Note, or may release the whole or any part of any



                                      -2-
<PAGE>   60

collateral security and/or liens given to secure the payment of this Note, or
may release from liability on account of this Note any one or more of the
makers, endorsers, guarantors and/or other parties thereto, all without notice
to them or any of them; and such deferment, postponement, renewal, extension,
acceptance of additional collateral or security and/or release shall not in any
way affect or change the obligation of any such maker, endorser, guarantor or
other party to this Note, or of any who may become liable for the payment
thereof.

         The Borrower shall pay a "late charge" of five percent (5%) of any
payments of principal and/or interest due when paid more than five days after
the due date thereof (provided that in no event shall said "late charge" result
in the payment of interest in excess of the maximum lawful rate of interest
permitted by applicable law), to cover the extra expenses involved in handling
delinquent payments; and provided that the late charge shall not be applicable
to the payment due on the Maturity Date.

         The term "maximum lawful rate of interest" as used herein shall mean a
rate of interest equal to the higher or greater of the following: (a) the
"applicable formula rate" defined in Tennessee Code Annotated Section
47-14-102(2), or (b) such other rate of interest as may be charged under other
applicable laws or regulations.

         This Note is a secured Note.

         This Note has been executed and delivered in, and shall be governed by
and construed according to the laws of the State of Tennessee except to the
extent pre-empted by applicable laws of the United States of America.

         This Note may not be changed or terminated without the prior written
approval of the Lender and the Borrower. No waiver of any term or provision
hereof shall be valid unless in writing signed by the holder.

         This Note is one of the Revolving Credit Notes issued by Borrower
pursuant to the Loan Agreement. This Note reflects in part an amendment,
restatement, and increase to the revolving credit indebtedness previously
evidenced by that certain Amended and Restated Revolving Credit Note payable to
the order of SunTrust Bank, Nashville, N.A. in the principal amount of
$12,000,000 dated as of June 25, 1996, which Amended and Restated Revolving
Credit Note was assigned by SunTrust Bank, Nashville, N.A. to Agent. Subsequent
to the assignment to Agent, the revolving credit indebtedness was increased
from time to time, the last such increase being an increase to $35,000,000 and
separate amended and restated notes were issued to the Lenders (as defined in
the Loan Agreement) to evidence the amended, restated, and increased revolving
credit indebtedness. This Note is not (and is not intended to be) a novation of
the revolving credit indebtedness evidenced by the previously issued amended
and restated revolving credit notes, but is intended to reflect an increase in
the principal amount and an amendment to the terms thereof.

                  FORM OF OPINION LETTER OF BORROWER'S COUNSEL

                             May ____________, 1998


SunTrust Bank, Nashville, N.A., Agent
201 Fourth Avenue North
Nashville, TN 37219
Attention: Karen Ahern

Dear Ms. Ahern:

         We have acted as counsel to AmSurg Corp., a Tennessee corporation (the
"Borrower"), in connection with the execution by the Borrower of that certain
Third Amended and Restated Loan Agreement dated as of May ______, 1998 by and 
among Borrower, SunTrust Bank, Nashville, N.A., Agent (the "Agent"), and the
Lenders, described therein (the "Loan Agreement"), the Revolving Credit Notes,
and certain other loan documents executed in connection with the Loan Agreement
(the Loan Agreement, the Revolving Credit Notes, and such other loan documents
executed by the Borrower are collectively referred to herein as the
"Transaction Documents").

         This Opinion Letter is delivered to, and for the benefit of, the Agent
and the Lenders, pursuant to the requirements of the Loan Agreement. All terms
used, but not defined herein shall have the meanings ascribed to them in the
Loan Agreement or the Accord (see below).

         This Opinion Letter is governed by, and shall be interpreted in
accordance with, the Legal Opinion Accord (the "Accord") of the ABA Section of
Business Law (1991). As a consequence, it is subject to a number of
qualifications, exceptions, definitions, limitations on coverage and other
limitations, all as more particularly described in the Accord, and this Opinion
Letter should be read in conjunction therewith.

         Solely as to matters of fact, but not as to the legal conclusions that
are the subject of this opinion, we have relied upon representations made by
Borrower in the Transaction Documents.

         The Law covered by the opinions expressed herein is limited to the
federal Law of the United States and the Law of the State of Tennessee.

         Based on the foregoing, and subject to the assumptions, limitations,
and qualifications set forth herein, we are of the opinion that:
<PAGE>   74

         1. Borrower is a corporation, duly organized, validly existing, and in
good standing under the laws of the State of Tennessee. Borrower has the
corporate power and corporate authority under such laws to enter into and
perform its obligations under the Transaction Documents.

         2. The Transaction Documents have been duly authorized by all
necessary Corporate action on the part of Borrower and have been duly executed
and delivered by the Borrower.

         3. The Transaction Documents are enforceable against the Borrower.

         Our opinion in paragraph 3 is further subject to the qualification
that certain waivers, procedures, remedies, and other provisions of the
Transaction Documents may be unenforceable under or limited by applicable law;
provided, however, that the inclusion of such waivers, procedures, remedies,
and other provisions does not render the Transaction Documents invalid as a
whole, and subject to the other qualifications and limitations set forth
herein, there exist in the Transaction Documents or pursuant to applicable law,
legally adequate remedies for the practical realization of the principal
benefits reasonably intended to be provided by the Transaction Documents,
subject to the consequences of any delay that may result from limitations
imposed by applicable law.

         In making our examinations and in expressing our opinions, we have
assumed that the Transaction Documents have been executed and delivered for
adequate consideration.

         The General Qualifications apply to all of the opinions set forth
above.

         We hereby confirm to you that there are no actions or proceedings
against the Borrower, pending or threatened in writing, before any court,
governmental agency or arbitrator that affect the enforceability of the
Transaction Documents.

         This Opinion Letter may be relied upon by Agent and the Lenders only
in connection with the Transaction Documents and may not be used or relied upon
by any other person for any purpose whatsoever, except to the extent authorized
in the Accord, without in each instance our prior written consent.

                               Very truly yours,
