                           FORWARD-LOOKING STATEMENTS

         This report and other information that is provided by PhyCor, Inc.
("PhyCor" or the "Company") contain forward-looking statements including those
regarding the acquisition of additional clinics, the development of additional
IPAs, the adequacy of PhyCor's capital resources and other statements regarding
trends relating to various revenue and expense items. Many factors, including
PhyCor's ability to consolidate clinics and operate them profitably,
competition, regulatory developments and changes, the profitability of capitated
fee arrangements and other methods of payment for medical services, the fact
that the physician groups with which PhyCor affiliates are exposed to the risk
of professional liability claims, its dependence on the revenue generated by its
affiliated clinics and other uncertainties, could cause actual results to differ
materially from those projected in such forward-looking statements. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Risk Factors."


                                     PART I

ITEM 1. BUSINESS

COMPANY OVERVIEW

         PhyCor is a physician practice management company ("PPM") that
acquires and operates multi-specialty medical clinics and develops and manages
independent practice associations ("IPAs"). PhyCor's objective is to organize
physicians into professionally managed networks that assist physicians in
assuming increased responsibility for delivering cost-effective medical care,
while attaining quality clinical outcomes and patient satisfaction. As of
December 31, 1997, the Company operated 55 clinics with 3,863 physicians in 28
states. The Company also manages IPAs, which are networks of independent
physicians, that, as of December 31, 1997, included over 19,000 physicians in 28
markets. As of December 31, 1997, the Company's affiliated physicians provided
capitated medical services to approximately 1,132,000 members, including
approximately 174,000 Medicare members.

         The Company's strategy is to position its affiliated multi-specialty
medical clinics and IPAs to be the physician component of organized health care
systems. PhyCor targets 




                                       2
<PAGE>   3

for acquisition primary care-oriented multi-specialty medical clinics with
significant market shares and established reputations for providing quality
medical care. The Company is also assisting independent physicians in particular
markets in developing new physician groups that enter into long-term agreements
with the Company. The Company focuses its IPA development and management efforts
in markets that have characteristics indicating opportunities for rapid
enrollment growth and attractive capitation rates. The Company generates
increased demand for the services and capabilities of its affiliated physician
organizations and achieves growth through the addition of physicians, the
expansion of managed care relationships and the addition and expansion of
ancillary services.

         PhyCor believes that primary care-oriented multi-specialty physician
organizations are a critical element of organized health care systems, because
physician decisions determine the cost and quality of care. PhyCor believes that
physician-driven organizations, including multi-specialty medical clinics, IPAs
and the combination of such organizations, present more attractive alternatives
for physician consolidation than hospital or insurer/health maintenance
organization ("HMO")-controlled organizations. The combination of PhyCor's
multi-specialty medical clinic, IPA management capabilities and new
group-formation efforts enables the Company to offer physician practice
management services to substantially all types of physician organizations.

         PhyCor implements a number of programs and services at each clinic in
order to promote growth and efficiency, including strategic planning and
budgeting, which focus on cost containment and expense reduction. PhyCor
negotiates managed care contracts, enters into national purchasing agreements,
conducts productivity and procedure coding and charge capturing studies and
assists the clinics in physician recruitment efforts. The Company maintains
information processing systems for each of its clinics, which have expanded the
Company's accounting, billing, receivables management, scheduling and reporting
systems capabilities. The Company has also implemented a quality improvement
initiative designed to enhance the quality of patient service delivery systems
at each affiliated clinic through the maintenance and measurement of performance
standards and collection and review of patient evaluations.

MULTI-SPECIALTY MEDICAL CLINICS

         A multi-specialty medical clinic provides a wide range of primary and
specialty physician care and ancillary services through an organized physician
group practice representing various medical specialties. Multi-specialty medical
clinics historically have been locally owned organizations managed by practicing
physicians.

         PhyCor targets for acquisition primary care-oriented multi-specialty
clinics typically comprised of between 25 and 200 physicians that have
significant market shares and established reputations for providing quality
medical care. Most of the clinics with which PhyCor seeks to affiliate are the
largest multi-specialty clinics in their local markets. See "Clinic Operations"
below.

         The Company generates increased demand for the services and
capabilities of its affiliated physician organizations and achieves growth
through the addition of physicians, the expansion of managed care relationships
and the addition and expansion of ancillary 


                                       3
<PAGE>   4
 services. During 1997, the Company assisted its affiliated clinics in
recruiting approximately 400 new physicians. The Company also merged the
practices of 103 additional physicians into its existing clinics. The Company is
also assisting formerly unaffiliated physicians in particular markets to develop
new physician groups which enter into long-term service agreements with the
Company. In addition, the Company is developing physician networks around its
physician groups to enhance managed care contracting and to provide the
physician component of organized health care systems. Physicians in affiliated
physician groups may participate in IPAs developed and managed by North American
Medical Management, Inc. ("North American"), an entity acquired by the Company
in 1995, or PhyCor Management Corporation ("PMC"), an entity in which PhyCor
purchased a minority interest in 1995 and completed the acquisition of such
interests on March 31, 1998. See "Physician Networks." PhyCor is also
positioning the clinics for participation in organized health care systems by
establishing strategic alliances with HMOs, insurers, hospitals and other health
care providers and by enhancing medical management systems.

         Clinic Operations

         Upon the acquisition by PhyCor of a clinic's operating assets, the
affiliated physician group simultaneously enters into a long-term service
agreement with the Company. The Company, under the terms of the service
agreement, provides the physician group with the equipment and facilities used
in its medical practice, manages clinic operations, employs most of the clinic's
non-physician personnel, other than certain diagnostic technicians, and receives
a service fee.

         During 1997, the Company acquired the assets of 11 multi-specialty
clinics located in California, Florida, Hawaii, Indiana, Maryland, Tennessee,
Virginia and Washington. The Company's California, Hawaii, Maryland and
Washington affiliated clinics are the Company's first clinics in those states.
The Company also entered into an interim management services agreement with
Lakeview Medical Center, Inc. in Suffolk, Virginia in December 1997 and entered
into a long-term service agreement with the 31-physician multi-specialty clinic
effective January 1, 1998. The Company has also reached an agreement in
principle to acquire certain assets of a 70-physician multi-specialty group. The
Company expects to complete the acquisition on or about April 1, 1998. The
Company is pursuing other possible clinic acquisitions in both existing and new
markets. There can be no assurance that additional clinic acquisitions will be
successfully completed.

         In the third quarter of 1997, PhyCor announced that it had signed a
letter of intent with New York and Presbyterian Hospitals Care Network, Inc. to
create and operate a regional managed care contracting network, which will
include hospitals and IPAs in New York City, northern New Jersey and southern
Connecticut.

         In addition, on December 19, 1997, the Company executed a definitive
Agreement and Plan of Merger with Atlanta-based First Physician Care, Inc.
("FPC"), a physician management company which currently manages three
multi-specialty physician groups pursuant to long-term service agreements, one
multi-specialty group pursuant to an interim service agreement and directly
delivers medical services through three wholly-owned subsidiaries and owns a 395
physician IPA in New York. FPC is currently affiliated with approximately 200
physicians in the states of Florida, Georgia, Missouri, New York and Texas. On
December 22, 1997, the Company executed an Agreement and Plan of Merger with
Seattle-based CareWise, Inc. ("CareWise"), a demand management



                                       4
<PAGE>   5
services company which provides consumer decision support services to patients
to better enable patients to control their medical care. The Company anticipates
that both the FPC and CareWise transactions will be consummated during the
second quarter of 1998. There can be no assurance that any of the foregoing
transactions will be successfully completed.

         In January 1998, the Company announced its plans to restructure five of
its multi-specialty clinic operations with approximately 300 physicians and
provide for the divestiture of two additional clinics with approximately 70
physicians. In connection with these plans, the Company recorded a pre-tax
charge for asset revaluation of approximately $83 million in the fourth quarter
of 1997 and will incur approximately $22 million in the first quarter of 1998 in
pre-tax restructuring charges relating to anticipated costs which are to provide
for consolidating facilities and clinic operations and reduced overhead costs.

         In addition to the 3,863 physicians affiliated with the Company at
December 31, 1997, the PhyCor-affiliated physician groups employ approximately
550 physician extenders, which include physician assistants, nurse practitioners
and other mid-level providers. The Company believes physician extenders comprise
an important component of its integrated network strategy by efficiently
expanding the level of services offered in its clinics.

         The physician groups offer a wide range of primary and specialty
physician care and ancillary services. Approximately 53.0% of PhyCor's 
affiliated physicians are primary care providers, and approximately 47.0%
practice various medical and surgical specialties. The primary care physicians
are those in family practice, general internal medicine, obstetrics, pediatrics
and emergency and urgent care. The Company is assisting all of its clinics in
recruiting additional primary care physicians. Medical specialties include
allergy, cardiology, dermatology, endocrinology, gastroenterology, infectious
diseases, nephrology, neurology, occupational medicine, oncology, pulmonology
and rheumatology. Surgical specialties include general surgery, ophthalmology,
orthopedics, otolaryngology, thoracic surgery and urology. The clinics vary in
the number and types of specialties offered. Substantially all of the physicians
practicing in the clinics are certified or eligible to be certified by the
applicable medical specialty boards.

         The clinics also offer a wide array of ancillary services. Most clinics
provide a range of imaging services, which may include CAT scanning,
mammography, nuclear medicine, ultrasound and x-ray. In addition, many of the
clinics have clinical laboratories and pharmacies. Ambulatory surgery units and
rehabilitation services are in place or being planned in many clinics, in some
cases through joint ventures. Several of the clinics have diabetes centers,
pharmaceutical clinical trial programs and weight management programs. Some
offer renal dialysis and participate, usually by joint venture, in home infusion
therapy. Ancillary revenue accounted for approximately 26.7% of gross clinic
revenue for the year ended December 31, 1997 compared to 25.2% for the year
ended December 31, 1996.

         In connection with an acquisition of assets and execution of a service
agreement, the Company investigates the history and reputation of the physician
group and the individual physicians. The Company obtains representations and
covenants from the physician group with respect to historical financial
performance and employment and licensure of individual physicians. As part of
its services performed under the service agreement, PhyCor personnel undertake
administrative tasks in connection with obtaining and maintaining liability
insurance for the physician group, including maintaining and reviewing files
relating to physician licensure and certification. PhyCor does not, however,
control the practice of medicine by physicians or compliance by them with
licensure or certification requirements. PhyCor's affiliated physicians maintain
full professional control over their medical practices, determine which
physicians to hire or terminate and set their own standards of practice in order
to promote high quality health care.

         PhyCor Operations

         Pursuant to its service agreements with physician groups, PhyCor
manages all aspects of the clinics other than the provision of medical services,
which is controlled by the physician groups. At each clinic, a joint policy
board equally comprised of physicians and



                                       7
<PAGE>   8

PhyCor personnel focuses on strategic and operational planning, marketing,
managed care arrangements and other major issues facing the clinic. The joint
policy board involves experienced health care managers in the decision making
process and brings increased discipline and accountability to clinic operations.
PhyCor is not engaged in the practice of medicine.

         PhyCor enhances clinic growth by expanding managed care arrangements,
assisting in the recruitment and merger of physicians and expanding and adding
ancillary services. PhyCor works closely with the physician groups in targeting
and recruiting physicians from outside the community and merging physicians in
sole practice or single specialty groups, especially primary care groups, into
the clinics' physician groups. PhyCor assists in the development of new and
expanded ancillary services by providing the needed capital resources and
management services.

         Management believes its clinics have the opportunity to form
relationships with managed care organizations, insurance companies and hospitals
to create high-quality, cost-effective health care delivery systems. The Company
is aligning its affiliated clinics with low-cost, high-quality hospitals and
related providers in each of its markets and through various relationships is
seeking to more closely coordinate the overall delivery of health care to
patients. These plans may include participation by affiliated physicians in
physician networks developed and managed by PhyCor or PMC. See "Physician
Networks." Pursuant to certain of the Company's relationships with managed care
organizations and insurance companies, responsibility for physician services,
hospital utilization and overall medical management is assumed by the physician
networks being developed by PhyCor-affiliated clinics. The Company believes that
medical management performed within physician organizations can yield the
greatest value in quality-driven, cost-effective health care and that premiums
collected from purchasers of health care will be allocated based upon the value
of the services performed by the health care provider members of organized
health care systems.

         The Company sponsors the PhyCor Institute for Healthcare Management
which provides practical managed care and medical management training for
physicians affiliated or considering affiliation with PhyCor. Through the
Institute's efforts, physicians in many locations work together to achieve
"economies of intellect" and best practice performance through shared data and
experience. The Company believes that, in the future, its ability to
differentiate its physician organizations based upon quality clinical
performance will increasingly impact financial performance.

         The Company focuses the attention of the physician groups on practice
patterns. This effort emphasizes outcomes measurement and management and is
intended to improve the physicians' ability to attain the desired clinical
results while containing the utilization of health resources. Similarly, the
Company's quality service initiative seeks to improve the patient's overall
experience with the health care delivered within the Company's affiliated
clinics and networks.

         The Company provides support for the selection and implementation of
information systems at its clinics. The Company has selected certain practice
management and other systems considered to be most effective for capitated risk
management, provider profiling and outcomes analysis for implementation at its
clinics. These systems are designed to



                                       8
<PAGE>   9

allow physician organizations to successfully capture information that will
enable them to more effectively manage the risk associated with capitated
arrangements.

         The Company also negotiates national arrangements that provide cost
savings to its clinics through economies of scale in malpractice insurance,
supplies and equipment. In addition, PhyCor has a service improvement program
that aligns staffing with the volume and service needs of its physician
organizations and focuses on measuring and improving patient satisfaction. Upon
assuming the operations of a clinic, the Company implements certain business
operating policies and reviews procedure coding practices in each clinic.

         Service Agreements

         The long-term service agreements currently entered into by the Company
are for terms of 40 years. Long-term agreements entered into prior to 1994 are
generally for terms of 30 years. These agreements cannot be terminated by the
Company or the physician groups without cause, which includes material default
or bankruptcy. Upon the expiration of the term of a service agreement or in the
event of termination, the physician group must purchase all of the related
tangible and intangible assets owned by the subsidiary of the Company providing
services to that physician group, generally at then current book value. The
physician group agrees not to compete with PhyCor during the term of the service
agreement and substantially all of the physicians agree not to compete with the
physician group for a period of time or agree to pay liquidated damages if they
compete. The Company agrees not to affiliate with other multi-specialty groups
in the clinic's service area during the term of the service agreement.

         Under substantially all of its service agreements, the Company receives
a service fee equal to the clinic expenses it incurred plus a percentage of
operating income of the clinic (net clinic revenue less certain contractually
agreed upon clinic expenses before physician distributions) and, under all other
service agreements except one described below, a percentage of net clinic
revenue. In 1997, approximately 94% of revenue from clinics was derived from
contracts based on a percentage of clinic operating income, approximately 1% of
revenue from clinics was derived from contracts based on a percentage of net
clinic revenue and approximately 4% of revenue from clinics was derived from
contracts based on a combination of a percentage of clinic operating income and
net clinic revenue. As clinic operating income improves, whether as a result of
increased revenue or lower expenses, PhyCor's service fees increase. Under one
service agreement, PhyCor's revenue is based on a flat fee, and it represented
approximately 1% of revenue from clinics in 1997.

         Several of the Company's service agreements contain provisions granting
the physician groups termination rights or rights of first refusal in certain
events. Many of the service agreements provide that if any person or persons
acquire the right to vote 50% or more of PhyCor's Common Stock, the physician
group may terminate the service agreement, unless the transaction was approved
by PhyCor's Board of Directors or subsequently approved by two-thirds of
PhyCor's directors who are not members of management or affiliates of the
acquiring person. The physician group in Lexington, Kentucky may also terminate
its service agreement if an entity named therein acquires 15% or more of the
Company's outstanding Common Stock. Other groups may terminate their service
agreement in the event of a merger where PhyCor does not survive or a takeover
or sale of substantially all the assets of PhyCor or in the event of a sale of
all or substantially all of the assets or capital stock of the PhyCor subsidiary
with whom the 



                                       9
<PAGE>   10

service agreement was entered into. Some physician groups have rights of first
refusal to purchase the clinic assets owned by PhyCor if PhyCor determines to
sell such assets. The above provisions could have an adverse effect on any
efforts to take control of PhyCor without the consent of the Board of Directors
and the physician groups having these rights.

PHYSICIAN NETWORKS

         The Company believes that the health care industry will continue to be
driven by local market factors and that organized providers of health care, like
IPAs, will play a significant role in delivering cost-effective, quality medical
care. IPAs offer physicians an opportunity to participate in expanding organized
health care systems and assistance in contracting with insurance companies and
HMOs, and other large purchasers of health care services. IPAs consolidate
independent physicians by providing general organizational structure and
management to the physician network. IPAs provide or contract for medical
management services to assist physician networks in obtaining and servicing
managed care contracts and enable previously unaffiliated physicians to assume
and more effectively manage capitated risk.

         As of December 31, 1997, PhyCor managed IPAs with over 19,000
physicians in 28 markets. The Company establishes management companies through
which all health plan contracts are negotiated. These management companies, in
which physicians may have an equity interest, provide information and operating
systems, actuarial and financial analysis, medical management and provider
contract services to the IPA. PhyCor assists physicians in forming networks to
develop a managed care delivery system in which the IPA accepts fiscal
responsibility for providing a wide range of medical services. PhyCor intends to
continue to develop primary care-oriented health care delivery systems in
certain markets that do not have established managed care networks.

         In June 1995, PhyCor purchased a minority interest in PMC and manages
PMC pursuant to a ten-year administrative services agreement. PMC develops and
manages IPAs and provides other services to physician organizations. In February
1998, PhyCor sent notices to the PMC shareholders of its intention to exercise
its option to purchase the remaining equity interest of PMC. The acquisition was
completed on March 31, 1998.

REGULATION

         General

         The health care industry is highly regulated, and there can be no
assurance that the regulatory environment in which the Company operates will not
change significantly in the future. In general, regulation of health care
companies is increasing.

         Every state imposes licensing requirements on individual physicians and
on facilities and services operated by physicians. In addition, federal and
state laws regulate HMOs and other managed care organizations. Many states
require regulatory approval, including certificates of need, before establishing
certain types of health care facilities, offering certain services or making
expenditures in excess of statutory thresholds for health care equipment,
facilities or programs. To date, neither the Company's clinics nor its managed
IPAs have been required to obtain certificates of need for their activities.



                                       10
<PAGE>   11
         In connection with the expansion of existing operations and the entry
into new markets and managed care arrangements, the Company and its affiliated
practice groups as well as its managed IPAs may become subject to compliance
with additional regulation.

         The Company and its clinics and managed IPAs 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. At an
increasing rate, federal, state and local governments are expanding the
regulatory requirements on businesses, including medical practices. The
imposition of these regulatory requirements may have the effect of increasing
operating costs and reducing the profitability of the Company's operations.

         PhyCor's managed IPAs and affiliated physician groups enter into
contracts and joint ventures with licensed insurance companies, such as HMOs,
whereby the IPAs and affiliated physician groups may be paid on a capitated fee
basis. Under capitation arrangements, health care providers bear the risk,
subject to certain loss limits, that the aggregate costs of providing medical
services to members will exceed the premiums received. To the extent that the
IPAs and affiliated physician groups subcontract with physicians or other
providers for those physicians or other providers to provide services on a
fee-for-service basis, the managed IPAs and affiliated physician groups may be
deemed to be in the business of insurance, and thus, subject to a variety of
regulatory and licensing requirements applicable to insurance companies or HMOs
resulting in increased costs to the managed IPAs and affiliated physician
groups, and corresponding lower revenue to PhyCor. There can be no assurance,
however, that the Company or its managed IPAs and affiliated physician groups
will not be adversely affected by such regulations. In connection with two
recent multi-specialty medical clinic acquisitions, the Company acquired HMOs
previously affiliated with the clinics and in another multi-specialty medical
clinic acquisition, the Company agreed to provide management services to the
physician group and the HMO owned by the physician group. The HMO industry is
highly regulated at the state level and is highly competitive. Additionally, the
HMO industry has been subject to numerous legislative initiatives within the
past several years that would increase potential HMO liability to patients,
resulting in increased costs to HMOs and correspondingly reduced revenue to
PhyCor. Certain aspects of health care reform legislation being considered at
the federal level have direct and indirect consequences for the HMO industry.
There can be no assurance that developments in any of these areas will not have
an adverse effect on the Company's wholly-owned HMOs or on HMOs in which the
Company has a partial ownership interest or other financial involvement.

         Many of the payor contracts entered into on behalf of PhyCor-managed
IPAs are based on capitated fee arrangements. Under capitation arrangements,
health care providers bear the risk, generally subject to certain loss limits,
that the aggregate costs of providing medical services to the members will
exceed the premiums received. The IPA management fees are based, in part, upon a
share of the remaining portion, if any, of capitated amounts of revenue after
payment of expenses. Some agreements with payors also contain shared risk
provisions under which the Company and IPA can earn additional compensation
based on utilization of hospital services by members and may be required to bear
a portion of any loss in connection with such shared risk provisions. Any such
loss could have a material adverse effect on the Company. The profitability of
the managed IPAs is dependent upon the ability of the providers to effectively
manage the per patient costs of providing medical services and the 


                                       11
<PAGE>   12
level of utilization of medical services. The management fees are also based
upon a percentage of revenue collected by the IPAs. Any loss of revenue by the
IPAs as a result of losing affiliated physicians, the termination of third party
payor contracts or otherwise could have a material adverse effect on management
fees derived by the Company from its management of IPAs. Through its service
fees, the Company also shares indirectly in capitation risk assumed by its
affiliated physician groups. Managed care providers and management companies
such as the Company are increasingly subject to liability claims arising from
utilization management, provider compensation arrangements and other activities
designed to control costs by reducing services. A successful claim on this basis
against PhyCor or an affiliated clinic or IPA could have a material adverse
effect on the Company.

         Federal and state antitrust laws also prohibit agreements in restraint
of trade, the exercise of monopoly power and other practices that are considered
to be anti-competitive. The Company believes that it is in material compliance
with federal and state antitrust laws in connection with the operation of its
clinics and its managed IPAs.

         The Company believes its operations are in material compliance with
applicable law and expects to modify its agreements and operations to conform in
all material respects to future regulatory changes. The ability of the Company
to operate profitably will depend in part upon the Company and its affiliated
physician groups and its managed IPAs obtaining and maintaining all necessary
licenses, certificates of need and other approvals and operating in compliance
with applicable health care regulations. The Company is unable to predict what
additional government regulations, if any, affecting its business may be enacted
in the future or how existing or future laws and regulations might be
interpreted. The failure of the Company or any of its affiliated physician
groups or managed IPAs to comply with applicable law could have a material
adverse effect on the Company.

         State Legislation

         At the state level, all state laws restrict the unlicensed practice of
medicine and many states also prohibit the splitting or sharing of fees with
non-physician entities and the enforcement of noncompetition agreements against
physicians. Many states also prohibit the corporate practice of medicine by an
unlicensed corporation or other non-physician entity and prohibit referrals to
facilities in which physicians have a financial interest. Additionally, the
Florida Board of Medicine has interpreted the Florida fee-splitting law very
broadly so as to arguably include the payment of any percentage-based management
fee, even to a management company that does not refer patients to a managed
group. PhyCor is affiliated with five physician groups in Florida, the service
agreements with these groups provide for percentage-based management fees. The
Florida Board of Medicine decision has been stayed pending judicial
interpretation of the decision. There can be no assurance that future
interpretations of, or changes in, these laws will not require structural and
organizational modifications of the Company's existing relationships with its
clinics or modifications in the existing relationships with its affiliated IPAs,
and there can be no assurance that the Company would be able to appropriately
modify its relationships. In addition, statutes in some states could restrict
expansion of the operations of the Company to those jurisdictions.

         Medicare Payment System

         The Company's affiliated physician groups and IPAs derived
approximately 22% of their net revenue in 1997 from payments for services
provided to patients enrolled in the federal Medicare program, including
patients covered by risk contracts. Clinics and IPAs managed by the Company
provide medical services under risk contracts to approximately 174,000 Medicare
members. The prior system of Medicare payments, other than for risk



                                       12
<PAGE>   13

contracts, was based on customary, prevailing and reasonable physician charges
and was phased out from 1992 through 1996 and replaced with an annually-adjusted
resource-based relative value scale ("RBRVS"). The Company believes that the
RBRVS fee scale may provide modest increases from historical levels in the per
patient fee-for-service Medicare revenue received by the physician groups and
IPAs with which the Company is affiliated, but does not believe that such
restraints on fee increases will result in a material adverse change in the
results of operations of the Company.

         Medicare Fraud and Abuse and Anti-Referral Provisions

         The provisions of the Social Security Act addressing illegal
remuneration (the "anti-kickback statute") prohibit providers and others from
soliciting, receiving, offering or paying, directly or indirectly, any form of
remuneration in return for the referral of, or the arranging for the referral
of, Medicare and other federal or state health program patients or patient care
opportunities, or in return for the purchase, lease arrangements or order of any
item or service that is covered by Medicare, certain other federal health
programs, or a state health program. The applicability of these provisions to
many business transactions in the health care industry, including the Company's
service agreements with physician groups, management agreements with IPAs and
joint ventures with other health care providers, has not been subject to any
significant judicial and regulatory interpretation.

         Management believes that although it is receiving remuneration under
its service agreements for management services and management fees under
management agreements for services to IPAs, the Company is not in a position to
make or influence referrals of patients or services reimbursed under Medicare or
state health programs to the physician groups or networks. Consequently, the
Company does not believe that the service fees and management fees payable to it
could be viewed as remuneration for referring or influencing referrals of
patients or services covered by such programs as prohibited by the anti-kickback
statute. Currently, the Company is not a separate provider of Medicare or state
health program reimbursed services, however, upon the consummation of the
Company's pending transaction with FPC, the Company, through its subsidiaries,
will be a provider in the states of Florida and Georgia. To the extent that the
Company is deemed to be a separate provider of medical services under its
service agreements or management agreements and to receive referrals from
physicians, the financial arrangements could be subject to scrutiny under the
anti-kickback statute. The Company does not believe that its operation of one
pharmacy under a provider number that is separate from the clinic's creates a
material risk under the anti-kickback statute.

         In connection with the transaction with Straub Clinic & Hospital,
Incorporated ("Straub"), the Company provides certain management services to
both a physician group practice and a hospital owned by the group. Because the
hospital is subject to extensive regulation and because hospital management
companies have, in some instances, been viewed as referral sources by federal
regulatory agencies, the relationship between PhyCor and the physician group
could come under increased scrutiny under the Medicare fraud and abuse law. In
addition, the federal government could in certain circumstances suspend or
prevent Straub from participating in government programs, which would have a
negative impact on PhyCor's revenues under its service agreement with Straub.

         In July 1991, the federal government published regulations that provide
exceptions, or "safe harbors," for business transactions that will be deemed not
to violate the 


                                       13
<PAGE>   14

anti-kickback statute. In September 1993, additional safe harbors were proposed
for eight activities including referrals within group practices consisting of
active investors. Although the arrangements between the Company, the clinics and
third parties, including the arrangements between North American and providers
and provider groups, do not in all instances fall within the protection offered
by these safe harbors or the proposed safe harbors, the Company believes its
operations are in material compliance with applicable Medicare fraud and abuse
laws. If the arrangements were found to be illegal, the Company, the physician
groups and/or the individual physicians would be subject to civil and criminal
penalties, including exclusion from participation in government reimbursement
programs, which could materially adversely affect the Company.

         Under legislation known as the "Stark Bill," referrals of Medicare and
Medicaid patients for certain services to entities by physicians with an
ownership interest in, or financial relationship with, that entity have been
prohibited. The covered services include physical therapy services, occupational
therapy services, radiology services, including MRI, CT and ultrasound,
radiation therapy services, durable medical equipment, parenteral and enteral
nutrients, equipment and supplies, prosthetics, orthotics and prosthetic
devices, home health services, outpatient prescription drugs and inpatient and
outpatient hospital services. The Company believes that its clinics are
operating in compliance with the language of statutory exceptions to the Stark
Bill, including, but not limited to, the exceptions for referrals to in-office
ancillary services within a group practice. As a result, the Company does not
believe that physicians who are members of the group practices practicing at its
clinics are prohibited from making referrals of designated health services to
the clinics.

         Impact of Health Care Regulatory Changes

         The United States Congress and many state legislatures routinely
consider proposals to reform or modify the health care system, including
measures that would control health care spending, convert all or a portion of
government reimbursement programs to managed care arrangements and balance the
federal budget by reducing spending for Medicare and state health programs.
These measures can affect a health care company's cost of doing business and
contractual relationships. For example, recent developments that affect the
Company's activities include: (i) federal legislation requiring a health plan to
continue coverage for individuals who are no longer eligible for group health
benefits and prohibiting the use of "pre-existing condition" exclusions that
limit the scope of coverage; (ii) a Health Care Financing Administration policy
prohibiting restrictions in Medicare risk HMO plans on a physician's
recommendation of other health plans and treatment options to patients; and
(iii) regulations imposing restrictions on physician incentive provisions in
physician provider agreements. There can be no assurance that such legislation,
programs and other regulatory changes will not have a material adverse effect on
PhyCor.

COMPETITION

         The business of providing health care related services is highly
competitive. Many companies, including professionally managed physician practice
management companies, have been organized to pursue the acquisition of medical
clinics, manage such clinics, employ clinic physicians or provide services to
IPAs. Large hospitals, other multi-specialty clinics and health care companies,
HMOs and insurance companies are also involved in 



                                       14
<PAGE>   15

activities similar to those of the Company. Some of these competitors have
longer operating histories and significantly greater resources than the Company.
There can be no assurance that the Company will be able to compete effectively,
that additional competitors will not enter the market, or that such competition
will not make it more difficult to acquire the assets of medical clinics or
develop or manage IPAs on terms beneficial to the Company. To the extent that
health care industry reforms make prepaid medical care more attractive and
provide incentives to form organized health care systems, the Company
anticipates facing greater competition. PhyCor's revenues are dependent upon the
continued success of the medical groups with which it has long-term service
agreements and IPAs that it manages. These organizations face competition from
several sources, including sole practitioners, single and multi-specialty groups
and staff model HMOs.

INSURANCE

         The Company maintains medical professional liability insurance on a
claims made basis for all of its operations. Insurance coverage under such
policies is contingent upon a policy being in effect when a claim is made,
regardless of when the events which caused the claim occurred. The Company also
maintains general liability and umbrella coverage on an occurrence basis. The
cost and availability of such coverage has varied widely in recent years. While
the Company believes its insurance policies are adequate in amount and coverage
for its current operations, there can be no assurance that the coverage
maintained by the Company is sufficient to cover all future claims or will
continue to be available in adequate amounts or at a reasonable cost. PhyCor and
its subsidiary operating the affiliated physician group are named as additional
insureds on the various policies maintained by each affiliated physician group,
including the professional liability insurance policies carried by the physician
group.

EMPLOYEES

         As of December 31, 1997, the Company employed approximately 19,000
people, including 135 in the corporate office. None of the Company's employees
is a member of a labor union, and the Company considers its relations with its
employees to be excellent.

ITEM 2. PROPERTIES

         The Company leases approximately 49,000 square feet of rentable space
at 30 Burton Hills Boulevard in Nashville, Tennessee, where the Company's
headquarters are located. The Company pays approximately $83,000 per month in
rent, which rental amount increases over the term of the lease to approximately
$87,000 per month in the final year. The lease expires in 2003. The Company
believes these arrangements and other available space are adequate for its
current uses. The Company plans to build new corporate headquarters adjacent to
its existing headquarters. The Company anticipates the new building, which is
scheduled to be completed in the third quarter of 1999, will be adequate for its
long-term uses. The Company currently is negotiating a synthetic lease
arrangement with Citibank, N.A. to finance the construction of the new building.
The Company intends to sublet its existing facility until the expiration of its
lease in 2003.

         The Company leases, subleases or occupies pursuant to its service
agreements the clinic facilities. In many cases, facilities are leased from the
physician groups with the lease cost generally included in the service fees paid
to PhyCor. In connection with the acquisition of the Company's affiliated clinic
in Lexington, Kentucky, the Company 


                                       15
<PAGE>   16

acquired the real estate used by the physician group, including the clinic's
main clinic facility in Lexington and other satellite facilities in Lexington
and the surrounding communities. Certain of such properties are subject to
mortgages assumed by the Company as a result of the transaction with an
aggregate outstanding principal balance as of February 28, 1998 of $3.7 million
and bear interest at rates ranging from 8.25% to 10.5%.

         In connection with the Company's acquisitions of its affiliated clinics
in Lafayette, Indiana, and St. Petersburg, Florida, the Company acquired the
real estate used by each of the physician groups. At the time of such
acquisitions, certain of the properties were subject to a mortgage, which
indebtedness was assumed by PhyCor as a result of the transactions and repaid in
full. The Company makes these facilities available to the physician groups
pursuant to the long-term service agreements with Lexington Clinic, Arnett
Clinic and St. Petersburg-Suncoast Medical Clinic, respectively.

         The Company may from time to time acquire real estate in connection
with the acquisition of clinic assets. The Company anticipates that as the
clinics continue to grow and add new services, expanded facilities will be
required. Such transactions may require PhyCor's assistance in obtaining
financing of the property on behalf of the physician groups.

ITEM 3. LEGAL PROCEEDINGS

         Certain litigation is pending against the physician groups affiliated
with the Company and IPAs managed by the Company. The Company has not assumed
any liability in connection with such litigation. Claims against the physician
groups and IPAs could result in substantial damage awards to the claimants which
may exceed applicable insurance coverage limits. While there can be no assurance
that the physician groups and IPAs will be successful in any such litigation,
the Company does not believe any such litigation will have a material adverse
effect on the Company. Certain other litigation is pending against the Company
and certain subsidiaries of the Company none of which management believes would
have a material adverse effect on the Company's financial position or results of
operations on a consolidated basis. Certain litigation is pending against
subsidiaries of North American which was outstanding prior to the acquisition of
North American by the Company. The Company is indemnified by certain former
shareholders of North American for any damages as a result of the litigation and
the amount of any additional payments to be made to the former shareholders of
North American would be offset by any damages resulting from such litigation.
While there can be no assurance that the North American subsidiaries will be
successful in any such litigation, the Company does not believe that the gross
contingency related to North American is material and the Company does not
believe that any such litigation will have a material adverse effect on the
Company.

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


OVERVIEW

         The Company acquires and operates primary care-oriented multi-specialty
medical clinics and develops and manages IPAs. A substantial majority of the
Company's revenue in 1997 and 1996 was earned under service agreements with
multi-specialty clinics. Revenue earned under substantially all of the service
agreements is equal to the net revenue of the clinics, less amounts retained by
physician groups. The service agreements contain financial incentives for the
Company to assist the physician groups in increasing clinic revenues and
controlling expenses.

         Upon the acquisition by PhyCor of a clinic's operating assets, the
affiliated physician group simultaneously enters into a long-term service
agreement with the Company. Under the terms of the service agreement, the
Company provides the physician group with the equipment and facilities used in
its medical practice, manages clinic operations, employs most of the clinic's
non-physician personnel, other than certain diagnostic technicians, and receives
a service fee.

         The affiliated physicians maintain full professional control over their
medical practices, determine which physicians to hire or terminate and set their
own standards of practice in order to promote high quality health care. Pursuant
to its service agreements with physician groups, PhyCor manages all aspects of
the clinic other than the provision of medical services, which is controlled by
the physician groups. At each clinic, a joint policy board equally comprised of
physicians and PhyCor personnel focuses on strategic and operational planning,
marketing, managed care arrangements and other major issues facing the clinic.

         Under substantially all of its service agreements, the Company receives
a service fee equal to the clinic expenses it has incurred plus a percentage of
operating income of the clinic (net clinic revenue less certain contractually
agreed upon clinic expenses before physician distributions) and, under all other
service agreements except one described below, a percentage of net clinic
revenue. In 1997, approximately 94% of revenue from clinics was derived from
contracts based on a percentage of clinic operating income, approximately 1% of
revenue from clinics was derived from contracts based on a percentage of net
clinic revenue and approximately 4% of revenue from clinics was derived from
contracts based on a combination of a percentage of clinic operating income and
net clinic revenue. As clinic operating income improves, whether as a result of
increased revenue or lower expenses, PhyCor's service fees increase. Under one
service agreement, PhyCor's revenue is based on a flat fee, and it represented
approximately 1% of revenue from clinics in 1997.

         The Company currently amortizes the goodwill and other intangible
assets related to its service agreements over the periods during which the
agreements are effective, ranging from 25 to 40 years.  The Company recently
has engaged in discussions with the staff of the Securities and Exchange 
Commission (the "Commission") regarding the appropriate amortization period for
goodwill and other intangible assets related to the Company's service
agreements. The Company has had discussions with the staff regarding the use of
a 25 year amortization period for such assets for all transactions to be entered
into in the future. There can be no assurance as to the outcome of the current
discussions with the Commission staff or the adoption by the Company of this
policy.  Had this policy been in place for 1997, the effect would have been an
approximate 3% reduction in net income before the nonrecurring charge discussed
below in "Liquidity." Management expects a similar effect on 1998 net income 
would result based on its current preliminary internal estimates of intangible
asset additions.

         To increase clinic revenue, the Company works with the affiliated
physician groups to recruit additional physicians, merge other physicians
practicing in the area into the affiliated physician groups, negotiate contracts
with managed care organizations and provide additional ancillary services. To
reduce or control expenses, among other things, PhyCor utilizes national
purchasing contracts for key items, reviews staffing levels to


                                       18
<PAGE>   19

make sure they are appropriate and assists the physicians in developing more
cost-effective clinical practice patterns.

         In November 1997, the Emerging Issues Task Force reached a consensus on
EITF 97-2, "Application of APB Opinion No. 16 and FASB Statement No. 94 to
Physician Practice Entities", which was passed in November 1997, and relates
primarily to the consolidation of physician practices controlled by a company.
The Company has not consolidated the physician practices it manages as it does
not have operating control as defined in EITF 97-2.

         The Company has increased its focus on the development of IPAs to
enable the Company to provide services to a broader range of physician
organizations, to enhance the operating performance of existing clinics and to
further develop physician relationships. The Company develops IPAs that include
affiliated clinic physicians to enhance the clinics' attractiveness as providers
to managed care organizations. Fees earned from managing the IPAs are based upon
a percentage of revenue collected by the IPAs and also upon a share of surplus,
if any, of capitated revenue of the IPAs. In 1997, approximately 6% of the
Company's revenue was earned under IPA management agreements.

         The table below indicates the number of clinics and physicians
affiliated with the Company and provides certain information with respect to the
Company's IPA operations at the end of the years indicated:

(1)Includes HMO, PPO, Medicare risk contracts and direct employer contracts, of
which approximately two-thirds of 1997 revenue was attributable to capitated
contracts.

         The payor mix varies from clinic to clinic and changes as acquisitions
are made. Since 1993, managed care revenue as a percentage of all revenue has  


                                       19

increased with significant increases since 1994 relating to the management of
IPAs. PhyCor believes that this trend will continue as a greater portion of the
population in the Company's markets joins managed care plans. The Company also
believes that the revenue received from managed care plans will increasingly be
in the form of capitation rather than fee-for-service contracts. Other changes
in payor mix have resulted from the acquisition of clinics with payor mixes
different from historical payor mixes experienced by the Company's affiliated
groups.

         Many of the payor contracts entered into on behalf of PhyCor-managed
IPAs are based on capitated fee arrangements. Under capitation arrangements,
health care providers bear the risk, subject to certain loss limits, that the
aggregate costs of providing medical services to members will exceed the
payments received. The IPA management fees are based, in part, upon a share of
the remaining portion, if any, of capitated amounts of revenues after payment of
expenses. Agreements with payors also contain shared risk provisions under which
the Company and the IPA can earn additional compensation based on utilization of
hospital services by members and may be required to bear a portion of any loss
in connection with such shared risk provisions. The profitability of the managed
IPAs is dependent upon the ability of the providers to effectively manage the
per patient costs of providing medical services and the level of utilization of
medical services. The management fees are also based upon a percentage of
revenue collected by the IPAs. Through its service fees, the Company also shares
indirectly in capitation risk assumed by its affiliated physician groups.

         During 1997, PhyCor affiliated with 11 multi-specialty clinics and
numerous smaller medical practices, and completed its previously announced
merger with Straub, located in Honolulu, Hawaii, adding $430.8 million in
assets. The principal assets acquired were accounts receivable, property and
equipment and service agreement costs, an intangible asset. The consideration
for the 1997 clinic acquisitions consisted of approximately 65% cash, 30%
liabilities assumed and 5% stock and convertible notes. The cash portion of the
consideration was funded by a combination of operating cash flow and borrowings
under the Company's bank credit facility. Property and equipment acquired
consisted mostly of clinic operating equipment, although the Company has
purchased certain land and buildings. Service agreement costs are amortized over
the life of the related service agreement, with recoverability assessed
periodically.

         In the third quarter of 1997, PhyCor announced that it had signed a
letter of intent with New York and Presbyterian Hospitals Care Network, Inc. to
create and operate a regional managed care contracting network, which will
include hospitals and IPAs in New York City, northern New Jersey and southern
Connecticut.

         In December 1997, the Company announced that it had signed two separate
agreements to purchase Atlanta-based First Physician Care, Inc., a provider of
practice management services, and Seattle-based CareWise, Inc., a nationally
recognized leader in the consumer decision support industry. Both transactions,
which are expected to be accounted for as pooling-of-interests, are expected to
close in the second quarter of 1998. The Company expects to issue approximately
5.6 million shares of Common Stock in conjunction with these transactions.

</TABLE>

(1)Excluding the effect of the nonrecurring charge in 1997, net operating
expenses, earnings from operations, earnings before income taxes and minority
interest, income tax expense and net earnings, as a percent of net revenue,
would have been 88.9%, 11.1%, 9.3%, 3.2% and 5.1%, respectively.


1997 COMPARED TO 1996

         Net revenue increased from $766.3 million for 1996 to $1.12 billion for
1997, an increase of 46.2%. Net revenue from the 31 service agreements and 13
IPA markets in effect for both years increased $75.3 million, or 12.8%, in 1997
compared with 1996. Same market growth resulted from the addition of new
physicians, the expansion of ancillary services, and increases in patient volume
and fees. The remaining increase results from the addition of new clinic service
agreements in 1997 and the timing of entering into new service agreements in
1996.

         During 1997, most categories of operating expenses were relatively
stable as a percentage of net revenue when compared to 1996, despite the large
increase in the dollar amounts resulting from acquisitions and clinic growth.
The decrease in clinic salaries, wages and benefits and other clinic expenses as
a percentage of net revenue resulted from the acquisition of clinics with lower
levels of these expenses compared to the existing base of clinics. The increase
in clinic supplies and rents and lease expense as a percentage of net 


                                       21
<PAGE>   22

revenue resulted from the acquisition of clinics with higher levels of these
expenses compared to the existing base of clinics. The addition of pharmacies at
certain existing clinics and new clinics which operate pharmacies also resulted
in increased clinic supplies expense as a percentage of net revenue. While
general corporate expenses decreased as a percentage of net revenue, the dollar
amount of general corporate expenses increased as a result of the addition of
corporate personnel to accommodate increased acquisition activity and to respond
to increasing physician group needs for support in managed care negotiations,
information systems implementation and clinical outcomes management programs.
The nonrecurring charge in 1997 relates to the asset revaluation of seven of the
Company's multi-specialty clinics. For a more detailed discussion of the
nonrecurring charge, see "See Liquidity and Capital Resources".

         The Company's effective tax rate was approximately 38.5% in 1997 and
1996.

1996 COMPARED TO 1995

         Net revenue increased from $441.6 million for 1995 to $766.3 million
for 1996, an increase of $324.7 million, or 73.5%. Net revenue from the 23
service agreements in effect as of January 1, 1995 increased $62.1 million, or
16.1%, in 1996. Same clinic growth resulted from the addition of new physicians,
the expansion of ancillary services, increases in both patient volume and fees.
The remaining increase results from the addition of new clinic service
agreements in 1996 and the timing of entering into new service agreements in
1995.

         During 1996, most categories of operating expenses were relatively
stable as a percentage of net revenue when compared to 1995, despite the large
increase in the dollar amounts resulting from acquisitions and clinic growth.
The increase in clinic salaries, wages and benefits resulted from the
acquisition of clinics with higher levels of these expenses compared to the
existing base of clinics and the addition of primary care physicians at existing
clinics. The ratio of staffing costs to net revenues is higher for primary care
practices than for specialty care. The reduction in purchased medical services
as a percentage of net revenue resulted from the Company's continuing efforts to
reduce clinic operating costs by improving the productivity of non-physician
personnel and limiting payments for outside medical services. While general
corporate expenses decreased as a percentage of net revenue, the dollar amount
of general corporate expenses increased as a result of the addition of corporate
personnel to accommodate increased acquisition activity and to respond to
increasing physician group needs for support in managed care negotiations,
information systems implementation and clinical outcomes management programs.

         Income tax expense increased from the prior year as a result of the
Company's increased profitability. The Company's effective tax rate was
approximately 38.5% in 1996.

SUMMARY OF OPERATIONS BY QUARTER

(1) Excluding the effect of nonrecurring charges, the Company's earnings before
taxes, net earnings and net earnings per share-diluted for the fourth quarter of
1997 would have been approximately $25.8 million, $16.0 million and $.24,
respectively. 
(2) Adjusted to reflect the three-for-two stock split effected June 1996.


LIQUIDITY AND CAPITAL RESOURCES

         At December 31, 1997, the Company had $203.3 million in working
capital, up from $182.6 million as of December 31, 1996. Also, the Company
generated $116.0 million of cash flow from operations in 1997 compared to $75.1
million in 1996. At December 31, 1997, net accounts receivable of $391.7 million
amounted to 72 days of net clinic revenue compared to $295.4 million and 73 days
at the end of the prior year.

         In the first quarter of 1997, the Company completed a public offering
of 7,295,000 shares of its Common Stock at a price of $30.00 per share. Net
proceeds from the offering of approximately $210.0 million were used to repay
bank debt and accrued interest. As a result of the issuance of Common Stock
during 1997, debt was 41.4% of total capitalization at December 31, 1997,
compared to 49.6% at the end of 1996.

         In 1997, $14.8 million of convertible subordinated notes issued in
connection with physician group asset acquisitions were converted into Common
Stock. These conversions, the issuance of Common Stock, option exercises and net
earnings for 1997 resulted in an increase of $258.8 million in shareholders'
equity compared to December 31, 1996.

         Capital expenditures during 1997 totaled $66.5 million. The Company is
responsible for capital expenditures at its affiliated clinics under the terms
of its service agreements. The Company expects to make approximately $75 million
in capital expenditures during 1998.

         Effective January 1, 1995, the Company completed its acquisition of
North American. The Company paid $20.0 million at closing and has made
additional payments pursuant to an earn-out formula during 1996 and 1997,
totaling $35.0 million. A final payment of $35.0 million will be made pursuant
to the earnout formula in 1998. A portion of the final payment will be paid in
shares of the Company's Common Stock.


                                       23
<PAGE>   24


         In addition, deferred acquisition payments are payable to physician
groups in the event such physician groups attain predetermined financial targets
during established periods of time following the acquisitions. If each group
satisfied its applicable financial targets for the periods covered, the Company
would be required to pay an aggregate of approximately $83.0 million of
additional consideration over the next five years, of which a maximum of $19.2
million would be payable during 1998.

         In the fourth quarter of 1997, PhyCor recorded a nonrecurring pre-tax
charge to earnings of $83.4 million related to the revaluation of assets of
seven of the Company's multi-specialty clinics. In addition, the Company also
announced that it expects to take an additional charge of approximately $22.0
million in the first quarter of 1998 relating to these clinics that will be
restructured or sold. The restructured groups primarily represent first
generation attempts at new group formations, and these charges address problems
that developed in these markets. The Company has modified its approach to this
type of market and the more recent new group formations have been more
successful.

         The Company also announced that it expects to record a pre-tax charge
to earnings of approximately $15.0 million in the first quarter of 1998 relating
to its terminated merger with MedPartners, Inc. This charge represents PhyCor's
share of investment-banking, legal, travel, accounting and other expenses
incurred during the merger process.

         In June 1995, the Company purchased a minority interest of 
approximately 9% in PMC and manages PMC pursuant to a 10-year administrative
services agreement. PMC develops and manages IPAs and provides other services to
physician organizations. PhyCor acquired the remaining interests of PMC on March
31, 1998 for an aggregate purchase price of approximately $23.0 million paid in
shares of the Company's Common Stock.

         PhyCor has been the subject of an audit by the Internal Revenue Service
(IRS) covering the years 1988 through 1993. The IRS has proposed adjustments
relating to the timing of recognition for tax purposes of certain revenue and
deductions relating to uncollectible accounts and the Company's relationship
with affiliated physician groups. PhyCor disagrees with the positions asserted
by the IRS, including any recharacterization, and is vigorously contesting these
proposed adjustments. The Company believes that any adjustments resulting from
resolution of this disagreement would not affect reported net earnings of
PhyCor, but would defer tax benefits and change the levels of current and
deferred tax assets and liabilities. For the years under audit, and potentially,
for subsequent years, any such adjustments could result in material cash
payments by the Company. PhyCor does not believe the resolution of this matter
will have a material adverse effect on its financial condition or results of
operations, although there can be no assurance as to the outcome of this matter.

         In July 1997, the Company completed modifications to its bank credit
facility, which included the revision of certain terms and condition and the
addition of seven participating financial institutions. The Company's bank
credit facility provides for a five-year, $250.0 million revolving line of
credit for use by the Company prior to July 2002 and a $150.0 million 364-day
facility for acquisitions, working capital, capital expenditures and general
corporate purposes. The total drawn cost under the facility is either .375% to
 .75% above the applicable eurodollar rate or the agents base rate plus .10% to
 .225% per annum. On 



                                       24
<PAGE>   25

October 17, 1997, the Company entered into an interest rate swap agreement to
fix the interest rate on $100.0 million of debt at 5.85% for a two-year period.
In March 1998, the Company obtained commitments from its bank group to expand
the existing bank credit facility to a total of $500.0 million. The expanded
facility, with terms similar to the existing facility, is expected to close in
the second quarter of 1998.

         The Company's current bank credit facility contains covenants which, 
among other things, require the Company to maintain certain financial ratios and
impose certain limitations or prohibitions on the Company with respect to: (i)
the incurrence of certain indebtedness, (ii) the creation of security interests
on the assets of the Company, (iii) the payment of cash dividends on, and the
redemption or repurchase of, securities of the Company, (iv) investments and (v)
acquisitions. The Company is required to obtain bank consent for an acquisition
with an aggregate purchase price of $75.0 million or more. The Company was in
compliance with such covenants at December 31, 1997.

         PhyCor has assessed its practice management systems, managed care
information systems, business information systems and other clinic systems for
compliance with the Year 2000 issue. The Company is in its normal process of
standardizing the various systems utilized by its clinics and IPAs. This
standardization includes implementation of Year 2000 compliant systems. The
Company has performed an assessment of its various clinics and IPAs to identify
which systems specifically require replacement or upgrade due to the Year 2000
issue in order to ensure timely upgrade or installation. The Company believes it
has a replacement strategy in place such that the Year 2000 issue will not have
a significant effect on its operations. Total capital costs to implement new
systems and to address the Year 2000 issue are expected to be less than $20.0
million.

         At March 19, 1998, the Company had cash and cash equivalents of
approximately $38.0 million and $134.6 million available under its current bank
credit facility. The Company believes that the combination of funds available
under the Company's anticipated expanded bank credit facility, together with
cash reserves and cash flow from operations, should be sufficient to meet the
Company's current planned acquisition, expansion, capital expenditure and
working capital needs through 1998. In addition, in order to provide the funds
necessary for the continued pursuit of the Company's long-term expansion
strategy, the Company expects to continue to incur, from time to time,
additional short-term and long-term indebtedness and to issue equity and debt
securities, the availability and terms of which will depend upon market and
other conditions. There can be no assurance that such additional financing will
be available on terms acceptable to the Company or that the expanded bank credit
facility will be entered into.

RISK FACTORS

         This discussion also identifies important cautionary factors that could
cause PhyCor's actual results to differ materially from those projected in
forward-looking statements of PhyCor and included herein or incorporated by
reference. In particular, forward-looking statements including, but not limited
to, those regarding future business prospects, the acquisition of additional
clinics, the development of additional IPAs, the adequacy of PhyCor's capital
resources, the future profitability of capitated fee arrangements and other
statements regarding trends relating to various revenue and expense items, could
be affected by a number of risks and uncertainties including those described
below.


                                       25

<PAGE>   26

         No Assurance of Continued Rapid Growth

         PhyCor's continued growth will be primarily dependent upon its ability
to achieve significant consolidation of multi-specialty medical clinics, to
sustain and enhance the profitability of those clinics and to develop and manage
IPAs. The process of identifying suitable acquisition candidates and proposing,
negotiating and implementing an economically feasible affiliation with a
physician group or formation or management of a physician network is lengthy and
complex. Clinic and physician network operations require intensive management in
a dynamic marketplace increasingly subject to cost containment pressures. There
can be no assurance that PhyCor will be able to sustain its historically rapid
rate of growth. The success of PhyCor's strategy to develop and manage IPAs is
largely dependent upon its ability to form networks of physicians, to obtain
favorable payor contracts, to manage and control costs and to realize economies
of scale. Many of the agreements entered into by physicians participating in
PhyCor-managed IPAs are not exclusive arrangements. The physicians, therefore,
could join competing networks or terminate their relationships with the IPAs.
There can be no assurance that PhyCor will be successful in acquiring additional
physician practice assets or PPMs, establishing new IPA networks or maintaining
relationships with affiliated physicians.

         Additional Financings

         PhyCor's multi-specialty medical clinic acquisition and expansion
program and its IPA development and management plans require substantial capital
resources. The operations of existing clinics require ongoing capital
expenditures for renovation and expansion and the addition of costly medical
equipment and technology utilized in providing ancillary services. PhyCor, in
certain circumstances, has acquired real estate in connection with clinic
acquisitions. PhyCor will require additional financing for the development of
additional IPAs and expansion and management of existing IPAs. PhyCor expects
that its capital needs over the next several years will exceed capital generated
from operations. PhyCor plans to incur indebtedness and to issue, from time to
time, additional debt or equity securities, including the issuance of PhyCor
Common Stock or convertible notes in connection with acquisitions. PhyCor's bank
credit facility requires the lenders' consent for borrowings in connection with
the acquisition of certain clinic assets. There can be no assurance that
sufficient financing will be available on terms satisfactory to PhyCor or at
all.

         Competition

         The business of providing health care related services is highly
competitive. Many companies, including professionally managed PPM companies like
PhyCor have been organized to pursue the acquisition of medical clinics, manage
such clinics, employ clinic physicians or provide services to IPAs. Large
hospitals, other multi-specialty clinics and health care companies HMOs and
insurance companies are also involved in activities similar to those of PhyCor.
Some of these competitors have longer operating histories and significantly
greater resources than PhyCor. There can be no assurance that PhyCor will be
able to compete effectively, that additional competitors will not enter the
market, or that such competition will not make it more difficult to acquire the
assets of multi-specialty clinics on terms beneficial to PhyCor.

         Dependence on Affiliated Physicians

         Substantially all of PhyCor's revenue is derived from service or
management agreements with PhyCor's affiliated clinics, the loss of certain of
which could have a material adverse effect on PhyCor as a result of the loss of
revenue from such agreements and the loss of any funds advanced by PhyCor to
cover expenses of such clinics. In addition, any material decline in revenue by
PhyCor's affiliated physician groups, whether as a result of physicians leaving
the affiliated physician groups or otherwise, could have a material adverse
effect on PhyCor.

         Risks Associated with Managed Care and Capitation; Reliance on 
Physician Networks

         Many of the payor contracts entered into on behalf of PhyCor-managed
IPAs are based on capitated fee arrangements. Under capitation arrangements,
health care providers bear the risk, subject to certain loss limits, that the
aggregate costs of providing medical services to the members will exceed the
premiums received. The IPA management fees are based, in part, upon a share of
the remaining portion, if any, of capitated amounts of revenue. Some agreements
with payors also contain "shared risk" provisions under which the Company and
IPA can earn additional compensation and may be required to bear a portion of
any loss in connection with such shared risk provisions based on utilization of
hospital services by members. Any such losses could have a material adverse
effect on PhyCor. The profitability of a capitated fee arrangement is dependent
upon the ability of the providers to effectively manage the per patient costs of
providing medical services and the level of utilization of medical services. The
management fees are also based upon a percentage of revenue collected by the
IPA. Any loss of revenue by the IPAs as a result of losing affiliated
physicians, the termination of third party payor contracts or otherwise could
have a material adverse effect on management fees derived by PhyCor. Managed
care providers and management entities such as PhyCor are increasingly subject
to liability claims arising from utilization management, provider compensation
arrangements and other activities designed to control costs by reducing
services. A successful claim on this basis against PhyCor or an affiliated
clinic or IPA could have a material adverse effect on PhyCor.

         Risks of Changes in Payment for Medical Services

         The United States Congress and many state legislatures routinely
consider proposals to reform or modify the health care system, including
measures that would control health care spending, convert all or a portion of
government reimbursement programs to managed care arrangements and reduce
spending for Medicare and state health programs. These measures can affect a
health care company's cost of doing business and contractual relationships. For
example, recent developments that affect PhyCor's activities include: (i)
federal legislation requiring a health plan to continue coverage for individuals
who are no longer eligible for group health benefits and prohibiting the use of
"pre-existing condition" exclusions that limit the scope of coverage; (ii) a
Health Care Financing Administration policy prohibiting restrictions in Medicare
risk HMO plans on a physician's recommendation of other health plans and
treatment options to patients; and (iii) regulations imposing restrictions on
physician incentive provisions in physician


                                       27
<PAGE>   28

provider agreements. There can be no assurance that such legislation, programs
and other regulatory changes will not have a material adverse effect on PhyCor.

         The profitability of PhyCor may be adversely affected by Medicare and
Medicaid regulations, cost containment decisions of third party payors and other
payment factors over which PhyCor has no control. The federal Medicare program
has undergone significant legislative and regulatory changes in the
reimbursement and fraud and abuse areas, including the adoption of the
resource-based relative value scale ("RBRVS") schedule for physician
compensation under Medicare, which may continue to have a negative impact on
PhyCor's revenue. Efforts to control the cost of health care services are
increasing. Many of PhyCor's physician groups are becoming affiliated with
provider networks, managed care organizations and other organized health care
systems, which often provide fixed fee schedules or capitation payment
arrangements that are lower than standard charges. Future profitability in the
changing health care environment, with differing methods of payment for medical
services, is likely to be affected significantly by management of health care
costs, pricing of services and agreements with payors. Because PhyCor derives
its revenues from the revenues generated by its affiliated physician groups and
from managed IPAs, further reductions in payments to physicians generally or
other changes in payment for health care services could have a material adverse
effect on PhyCor.

         Additional Regulatory Risks

         The health care industry and physicians' medical practices are highly
regulated at the state and federal levels. At the state level, all state laws
restrict the unlicensed practice of medicine, and many states also prohibit the
splitting or sharing of fees with nonphysician entities and the enforcement of
noncompetition agreements against physicians. Furthermore, most state
fee-splitting laws provide that it is a violation only if a physician shares
fees with a referral source. PhyCor is not a referral source for its managed
groups, and therefore the fee-splitting laws in most states should not restrict
the payment of a management fee by the physician groups to PhyCor. Many states
also prohibit the "corporate practice of medicine" by an unlicensed corporation
or other nonphysician entity that employs physicians. Currently, PhyCor merely
manages physician groups, and the physicians continued to be employed at the
group level by professional associations or corporations, which are specifically
authorized under most state laws to employ physicians. Upon consummation of the
FPC transaction, however, subsidiaries of PhyCor will directly employ physicians
in the states of Florida and Georgia.

         Additionally, the Florida Board of Medicine has interpreted the Florida
fee-splitting law very broadly so as to arguably include the payment of any
percentage-based management fee, even to a management company that does not
refer patients to a managed group. PhyCor is affiliated with five physician
groups in Florida, the service agreements with which provide for
percentage-based management fees. The Florida Board of Medicine decision has
been stayed pending judicial interpretation of the decision. Because of the
structure of the relationships of PhyCor with its affiliated physician groups
and managed IPAs, and because of the recent broad fee-splitting interpretation
in the State of Florida, there can be no assurance that review of PhyCor's
business by courts or health care, or other regulatory authorities will not
result in determinations that could adversely affect the financial condition or
results of operations of PhyCor. If for any reason PhyCor were found to have
violated the corporate practice of medicine or fee-splitting statutes, possible
consequences could include revocation or suspension of the physicians' license,
resulting in lowered revenue to PhyCor. Courts could also refuse to uphold the
contracts between PhyCor and its managed physicians on the


                                       28
<PAGE>   29

grounds that PhyCor was engaging in the unlicensed practice of medicine and that
therefore its contracts were invalid.

         On the federal level, federal law prohibits the offer, payment,
solicitation, or receipt of any form of remuneration in return for the referral
of, or the arranging for the referral of, Medicare or other federal 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
other federal or state health programs. In addition, federal law prohibits
physicians with certain financial relationships with health care providers from
referring certain types of Medicare or Medicaid reimbursed "designated health
services" to those providers unless the referral fits within an exception to the
law. One of the exceptions that is used most often requires that physician
groups be included within a definition of "group practice" in order to be
permitted to make referrals within the group. Federal antitrust laws also
prohibit conduct that may result in price fixing or other anticompetitive
conduct.

         The PhyCor arrangements have been carefully structured so that the
physician groups being managed fit within the definition of "group practice",
and all referrals from those physicians to ancillary centers are structured to
fit within an applicable exception to federal law. In addition, PhyCor does not
make or influence referrals to its managed or employed physicians, and the
compensation received by PhyCor is not directly related to any referral levels
between the parties. Nevertheless, because of the structure of the relationships
of PhyCor with its affiliated physician groups and managed IPAs, there can be no
assurance that review of PhyCor's business by courts or healthcare, tax,
regulatory authorities will not result in determinations that could adversely
affect the financial condition or results of operations of PhyCor, or that the
health care regulatory environment will not change in the manner that would
restrict PhyCor's existing operations or limit the expansion of PhyCor's
business or otherwise adversely affect PhyCor. In addition to civil and, in some
cases, criminal penalties for violation of Medicare and Medicaid statutes,
violators of these statutes may be excluded from further participation in
Medicare or state health care programs.

         Increased Government Scrutiny of Health Care Arrangements

         There is increasing scrutiny by law enforcement authorities, the Office
of Inspector General ("OIG") of the Department of Health and Human Services
("DHHS"), the courts, and the United States Congress of arrangements between
health care providers and potential referral sources to ensure that the
arrangements are not designed as a mechanism to exchange remuneration for
patient care referrals and opportunities. Investigators have also demonstrated a
willingness to look behind the documents evidencing a business transaction to
determine the underlying purpose of payments between health care providers and
potential referral sources. Enforcement actions have increased as evidenced by
recent highly publicized enforcement investigations of certain hospital
activities. Although, to its knowledge PhyCor is not currently the subject of
any investigation which is likely to have a material adverse effect on their
respective businesses, there can be no assurance that they will not be the
subject of investigations or inquiries in the future.


                                       29
<PAGE>   30

         Risks Associated with Straub Transaction

         In January 1997, PhyCor consummated its merger with Straub, an
integrated health care system with a 152-physician multi-specialty clinic and
159-bed acute care hospital located in Honolulu, Hawaii. In connection with the
transaction with Straub, PhyCor agreed to provide certain management services to
both a physician group practice and a hospital owned by the group. Because the
hospital is subject to extensive regulation and because hospital management
companies have, in some instances, been viewed as referral sources by federal
regulatory agencies, the relationship between PhyCor and the physician group
could come under increased scrutiny under the Medicare fraud and abuse law.

         Tax Audit

         PhyCor has been subject to an audit by the IRS covering the years 1988 
through 1993. The IRS has proposed adjustments relating to the timing of
recognition for tax purposes of certain revenue and deductions relating to
uncollectible accounts and PhyCor's relationship with affiliated physician
groups. PhyCor disagrees with the positions asserted by the IRS including any
recharacterization and is vigorously contesting these proposed adjustments.
PhyCor believes that any adjustments resulting from resolution of this
disagreement would not affect reported net earnings of PhyCor but would defer
tax benefits and change the levels of current and deferred tax assets and
liabilities. For the years under audit and, potentially, for subsequent years,
any such adjustments could result in material cash payments by PhyCor. PhyCor
does not believe the resolution of this matter will have a material adverse
effect on its financial condition, although there can be no assurance as to the
outcome of this matter.

         Applicability of Insurance Regulations

         PhyCor's managed IPAs enter into contracts and joint ventures with
licensed insurance companies, such as HMOs, whereby the IPAs may be paid on a
capitated fee basis. Under capitation arrangements, health care providers bear
the risk, subject to certain loss limits, that the aggregate costs of providing
medical services to members will exceed the premiums received. To the extent
that the IPAs subcontract with physicians or other providers for those
physicians or other providers to provide services on a fee-for-service basis,
the managed IPAs may be deemed to be in the business of insurance, and thus,
subject to a variety of regulatory and licensing requirements applicable to
insurance companies or HMOs resulting in increased costs to the managed IPAs,
and corresponding lower revenue to PhyCor. In connection with multi-specialty
medical clinic acquisitions, PhyCor has and may continue to acquire HMOs
previously affiliated with such clinics. The HMO industry is highly regulated at
the state level and is highly competitive. Additionally, the HMO industry has
been subject to numerous legislative initiatives within the past several years,
including initiatives that would pose additional liabilities on HMOs for patient
malpractice, thereby increasing costs to HMOs, which would result in
correspondingly lower revenue to PhyCor. There can be no assurance that
developments in any of these areas will not have an adverse effect on PhyCor's
wholly-owned HMOs or on HMOs in which PhyCor has a partial ownership interest or
other financial involvement.



                                       30
<PAGE>   31

         Risks Inherent in Provision of Medical Services

         The physician groups with which PhyCor affiliates and the physicians
participating in networks developed and managed by PhyCor are involved in the
delivery of medical services to the public and, therefore, are exposed to the
risk of professional liability claims. Claims of this nature, if successful,
could result in substantial damage awards to the claimants which may exceed the
limits of any applicable insurance coverage. Insurance against losses related to
claims of this type can be expensive and varies widely from state to state.
PhyCor does not control the practice of medicine by affiliated physicians or the
compliance with certain regulatory and other requirements directly applicable to
physicians, physician networks and physician groups. PhyCor is indemnified under
its service agreements for claims against the physician groups, maintains
liability insurance for itself and negotiates liability insurance for the
physicians affiliated with its clinics and under its management agreements for
claims against the IPAs and physician members. Successful malpractice claims
asserted against the physician groups, the managed IPAs or PhyCor, however,
could have a material adverse effect on PhyCor. Moreover, PhyCor may in the
future acquire entities, such as other PPMs that directly employ physicians. The
acquisition of such companies would subject PhyCor to increased risk of
malpractice liability, as well as increased scrutiny under healthcare
regulations and laws. 

         Anti-takeover Considerations

         PhyCor is authorized to issue up to 10,000,000 shares of preferred
stock, the rights of which may be fixed by the Board of Directors. In February
1994, the Board of Directors approved the adoption of a Shareholder Rights Plan
(the "PhyCor Rights Plan"). The PhyCor Rights Plan is intended to encourage
potential acquirers to negotiate with PhyCor's Board of Directors and to
discourage coercive, discriminatory and unfair proposals. PhyCor's stock
incentive plans provide for the acceleration of the vesting of options in the
event of a change in control. The PhyCor Charter provides for the classification
of its Board of Directors into three classes, with each class of directors
serving staggered terms of three years. Provisions in the executive officers'
employment agreements provide for post-termination compensation, including
payment of certain of the executive officers' salaries for 24 months, following
a change in control. Most physician groups may terminate their service
agreements with PhyCor in certain events, including a change in control of
PhyCor which is not approved by a majority of PhyCor's Board of Directors. A
change in control of PhyCor also constitutes an event of default under PhyCor's
bank credit facility. The foregoing matters may, together or separately, have
the effect of discouraging or making more difficult an acquisition or change of
control of PhyCor.

                   AMENDED AND RESTATED EMPLOYMENT AGREEMENT


                  This Amended and Restated Employment Agreement is made this
first day of August, 1997, between PhyCor, Inc., a Tennessee corporation (the
"Company") and ______________ ("Employee").

                              W I T N E S S E T H :

                  WHEREAS, the Company and Employee entered into an Employment
Agreement, dated August 30, 1991, as amended and restated March 25, 1994, and
have renegotiated the terms of such Employment Agreement; and

                  WHEREAS, the Company desires to continue to employ Employee
and Employee desires to accept such continued employment by the Company subject
to the terms and conditions contained herein; and

                  WHEREAS, in serving as an employee of the Company, Employee
will be in a position in which Employee will participate in the use and
development of confidential proprietary information about the Company's present
and future products, its customers and suppliers and the methods which the
Company and its employees use in competition with other companies, as to which
the Company desires to protect fully its rights;

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants and agreements herein set forth, the parties hereto agree as
follows:

                  1. Employment. The Company hereby employs Employee and
Employee accepts such employment with the Company, subject to the terms and
conditions set forth herein. Employee shall be employed as Chairman, President
and Chief Executive Officer of the Company, shall perform all duties and
services incident to his position, and such other duties and services as may be
prescribed by the Bylaws of the Company or established by the Board of Directors
of the Company from time to time; provided, however, that without Employee's
written consent: (i) the duties and services of Employee hereunder shall not be
materially altered in a manner inconsistent with Employee's position and
original duties hereunder, and (ii) Employee shall not be required to relocate
more than 25 miles from the Company's Nashville, Tennessee office. During his
employment hereunder, Employee shall devote his best efforts and attention, on a
full-time basis, to the performance of the duties required of him as an employee
of the Company.

                  2. Compensation. As compensation for services rendered by
Employee hereunder, Employee shall receive:

                           (a) An annual salary of $______, or such higher
                  salary as shall be determined by the Company's


<PAGE>   2



                  Compensation Committee payable in arrears in equal monthly
                  installments, plus insurance and other benefits equivalent to
                  the benefits provided other similar employees of the Company,
                  which are set forth in Appendix I hereto; and

                           (b) Six weeks of compensated vacation time, to be
                  taken at any time during each year of the term of this
                  Agreement;

                           (c) Participation in the Company's employee bonus
                  program as such program may be amended or modified by the
                  Company from time to time; and

                           (d) Reimbursement for all reasonable expenses
                  incurred by Employee in the performance of his duties under
                  this Agreement, provided that Employee submits verification of
                  such expenses in accordance with the policies of the Company.

                           (e) Immediate vesting of all options granted under
                  the Company's Employee Incentive Stock Plan or any
                  similar plan adopted by the Company.

                  3. Confidential Information and Trade Secrets.

                  3.1 Employee recognizes that Employee's position with the
Company requires considerable responsibility and trust, and, in reliance on
Employee's loyalty, the Company may entrust Employee with highly sensitive
confidential, restricted and proprietary information involving Trade Secrets and
Confidential Information.

                  3.2 For purposes of this Agreement, a "Trade Secret" is any
scientific or technical information, design, process, procedure, formula or
improvement that is valuable and not generally known to competitors of the
Company. "Confidential Information" is any data or information, other than Trade
Secrets, that is important, competitively sensitive, and not generally known by
the public, including, but not limited to, the Company's initial business plan,
business prospects, training manuals, product development plans, bidding and
pricing procedures, market strategies, internal performance statistics,
financial data, confidential personnel information concerning employees of the
Company, supplier data, operational or administrative plans, policy manuals, and
terms and conditions of contracts and agreements. The terms "Trade Secret" and
"Confidential Information" shall not apply to information which is (i) already
in Employee's possession at the time of employment (unless such information was
used in connection with formulating the Company's initial business plan,
obtained by Employee from the Company or was obtained by Employee in the course
of Employee's employment by the Company), (ii) received by Employee



                                        2

<PAGE>   3



from a third party with no restriction on disclosure, or (iii) required to be
disclosed by any applicable law.

                  3.3 Except as required to perform Employee's duties hereunder,
Employee will not use or disclose any Trade Secrets or Confidential Information
of the Company during employment, at any time after termination of employment
and prior to such time as they cease to be Trade Secrets or Confidential
Information through no act of Employee in violation of Section 3.

                  3.4 Upon the request of the Company and, in any event, upon
the termination of employment hereunder, Employee will surrender to the Company
all memoranda, notes, records, drawings, manuals or other documents pertaining
to the Company's business or Employee's employment (including all copies
thereof). Employee will also leave with the Company all materials involving any
Trade Secrets or Confidential Information of the Company. All such information
and materials, whether or not made or developed by Employee, shall be the sole
and exclusive property of the Company, and Employee hereby assigns to the
Company all of Employee's right, title and interest in and to any and all of
such information and materials.

                  4. Covenant Not to Compete.

                  4.1 Employee hereby covenants and agrees with the Company that
except as provided below, commencing on the date hereof and ending 24 months
after the stated expiration date of this Agreement (whether or not this
Agreement terminates at an earlier date), Employee will not directly or
indirectly (i) operate, develop or own any interest other than the ownership of
less than 5% of the equity securities of a publicly traded company, in any
business which has significant activities (viewed in relation to the business of
the Company, its subsidiaries and affiliates), or has announced intentions to
focus significant resources, relating to the ownership, management or operation
of multi-specialty medical clinics, physician group practices, independent
practice associations, or other similar entities (a "Business"); (ii) compete
with the Company or its subsidiaries and affiliates in the operation or
development of any Business within the United States of America; (iii) be
employed by any business which owns, manages or operates a Business; (iv)
interfere with, solicit, disrupt or attempt to disrupt any past, present or
prospective relationship, contractual or otherwise, between the Company, or its
subsidiaries or affiliates, and any customer, client, supplier or employee of
the Company, or its subsidiaries or affiliates; or (v) solicit any employee of
the Company, or its subsidiaries or affiliates, to leave their employment with
the Company or its subsidiaries or affiliates, as the case may be, or hire any
such employee to work for a Business; provided, however, that if Employee's
employment hereunder is terminated without cause prior to the expiration of this
Agreement, this provision shall



                                        3

<PAGE>   4



apply only for the period in which the Company is obligated to pay
and pays Employee's compensation.

                  4.2 If a judicial determination is made that any of the
provisions of this Section 4 constitutes an unreasonable or otherwise
unenforceable restriction against Employee, the provisions of this Section 4
shall be rendered void only to the extent that such judicial determination finds
such provisions to be unreasonable or otherwise unenforceable. In this regard,
the parties hereto hereby agree that any judicial authority construing this
Agreement shall be empowered to sever any portion of the territory or prohibited
business activity from the coverage of this Section 4 and to apply the
provisions of this Section 4 to the remaining portion of the territory or the
remaining business activities not so severed by such judicial authority.
Moreover, notwithstanding the fact that any provisions of this Section 4 are
determined not to be specifically enforceable, the Company shall nevertheless be
entitled to recover monetary damages as a result of the breach of such provision
by Employee. The time period during which the prohibitions set forth in this
Section 4 shall apply shall be tolled and suspended as to Employee for a period
equal to the aggregate quantity of time during which Employee violates such
prohibitions in any respect.

                  5. Specific Enforcement. Employee specifically acknowledges
and agrees that the restrictions set forth in Sections 3 and 4 hereof are
reasonable and necessary to protect the legitimate interest of the Company and
that the Company would not have entered into this Agreement in the absence of
such restrictions. Employee further acknowledges and agrees that any violation
of the provisions of Sections 3 or 4 hereof will result in irreparable injury to
the Company, that the remedy at law for any violation or threatened violation of
such Sections will be inadequate and that in the event of any such breach, the
Company, in addition to any other remedies or damages available to it at law or
in equity, shall be entitled to temporary injunctive relief before trial from
any court of competent jurisdiction as a matter of course and to permanent
injunctive relief without the necessity of proving actual damages.

                  6. Term. This Agreement shall continue for an initial period
of five years from the date hereof, unless sooner terminated by either party in
the manner set forth herein. Commencing 30 months prior to the end of the
initial term (and thereafter commencing on each date which is 30 months prior to
the end of the then term), the Company and Employee will negotiate in good faith
for the renewal of this Agreement for an additional term with the intent that
this Agreement shall at all times have a remaining term of greater than 24
months, subject to earlier termination as hereinafter provided. In the event (a)
the Company elects not to renew this Agreement or (b) the parties have failed to
enter into a renewal agreement by 24 months prior to the end of the then term



                                        4

<PAGE>   5



or extend the negotiation period, or (c) the parties have failed to enter into a
renewal agreement by the end of the extended negotiation period, then the
Company shall be deemed to have terminated this Agreement pursuant to the
provisions of Section 10 hereof, effective 24 months prior to the end of the
then term or effective the date the extended negotiation period terminates,
whichever is later. In the event Employee elects not to renew this Agreement,
Employee shall continue to be employed and perform his obligations and
responsibilities hereunder for the remaining term of this Agreement, and be
bound by the provisions of Section 4 of this Agreement as hereinafter provided.
The date upon which this Agreement and Employee's employment hereunder shall
terminate, whether pursuant to the terms of this Section or pursuant to any
other provision of this Agreement shall hereafter be referred to as the
"Termination Date."

                  7. Termination Upon Death of the Employee. In the event the
Employee dies during the term of this Agreement, this Agreement shall
immediately terminate and neither the Employee nor the Company shall have any
further obligations hereunder, except that (a) the Company shall continue to be
obligated under Section 2(a) hereof for any unpaid salary, bonus or unreimbursed
expenses owed to Employee or his estate that have accrued but not been paid as
of the Termination Date and any death benefits to which Employee is entitled
under the Company's benefit programs and (b) the Company shall pay to Employee's
estate an amount equal to three months salary.

                  8. Termination by Employee. Employee may at any time terminate
his employment by giving the Company ninety (90) days prior written notice of
his intent to terminate the Agreement. At the Termination Date, the Company
shall have no further obligation to Employee and Employee shall have no further
rights or obligations hereunder, except as set forth in Sections 3 and 4 above,
and except for the Company's obligation under Section 2(a) hereof for unpaid
salary, bonus or unreimbursed expenses that have accrued but have not been paid
as of the Termination Date. A termination by Employee pursuant to the last
sentence of Section 10 hereof shall not constitute a termination under this
Section 8.

                  9. Termination for Cause. The Company shall have the right at
any time to terminate Employee's employment immediately for cause, which shall
include any of the following reasons:

                           (a) If Employee shall violate the provisions of
                  Sections 3 or 4 of this Agreement, or shall fail to comply
                  with any other material term or condition of this Agreement or
                  shall engage in any material misconduct, neglect of duties or
                  failure to act which materially and adversely affects the
                  business or affairs of the Company; or

                           (b) If Employee shall (i) be convicted of a felony or
                  (ii) commit an act of dishonesty, fraud or embezzlement
                  against the Company.

Employee's obligations under Sections 3 and 4 hereof shall survive the
termination of the Agreement pursuant to this Section 9. In the event Employee's
employment hereunder is terminated in accordance with this Section, the Company
shall have no further obligation to make any payments to Employee hereunder
except for unpaid salary, bonus or unreimbursed expenses that have accrued but
have not been paid as of the Termination Date.

                  10. Termination Without Cause. In the event Employee is
terminated without cause during the term hereof (which shall not include a
termination pursuant to Sections 7, 8, 9 or 11), the Company shall pay Employee
all bonuses and unreimbursed expenses owed to Employee that have accrued but
have not been paid as of the Termination Date. The Company shall (a) continue to
pay to Employee his salary set forth in Section 2(a) hereof for the longer of
(i) the remaining term of this Agreement or (ii) a period of 24 months, (b)
continue to provide the insurance and other benefits of Section 2(a) hereof for
the period the salary is paid, (c) cause all grants of outstanding options,
restricted stock, bonus stock and any other incentive stock award to become
fully vested, and (d) cause all deferred compensation, supplemental retirement
programs and similar programs to become fully funded. The Company's obligations
pursuant to this Section 10 shall terminate immediately if Employee obtains
employment which is in violation of Section 4 hereof, whether or not the
provisions of Section 4 are then applicable to Employee.

                  In the event the Company is merged or consolidated with or
into another company and the Company does not survive the transaction or
survives only as a subsidiary of another company, or in the event any person or
group (as such terms are defined in Section 13 (d) of the Securities Exchange
Act of 1934, as amended) becomes the holder of 50% or more of the outstanding
voting securities of the Company or has the power, directly or indirectly, to
designate a majority of the members of the Board of Directors of the Company,
then in any such event a termination of this Agreement by Employee for any
reason within the first two years after the consummation of any of the foregoing
transactions shall constitute a termination without cause by the Company and
Employee shall be entitled to the amounts provided for in this Section 10.

                  11. Disability of Employee. If, on account of physical or
mental disability, Employee shall fail or be unable to perform his assigned
duties in any material respect for a period of sixty (60) consecutive days, the
Company shall pay Employee his full salary as set forth in Section 2(a) hereof
and shall provide the insurance, bonus and other benefits of Section 2(a) for a
period of six months from the date such disability began or for such shorter



                                        6

period as Employee is unable to perform his duties hereunder; provided, however,
that Employee's salary shall be reduced by any disability income paid to him
pursuant to any disability insurance policy maintained under this Agreement. In
the event Employee is unable to perform his duties hereunder after the
expiration of the six-month period, this Agreement shall automatically
terminate. Employee shall not be required to perform his obligations under
Section 1 hereof during any period of disability. Furthermore, the Company's
obligations pursuant to this Section 11 shall continue regardless of whether
Employee seeks, accepts or undertakes other employment during the six-month
period unless such employment is in violation of Section 4 hereof, as determined
in good faith by the Board of Directors.

                  12. Assignment.

                           (a) The rights and benefits of Employee under this
                  Agreement, other than accrued and unpaid amounts due under
                  Section 2(a) hereof, are personal to him and shall not be
                  assignable. Discharge of Employee's undertakings in Sections 3
                  and 4 hereof shall be an obligation of Employee's executors,
                  administrators, or other legal representatives or heirs.

                           (b) This Agreement may not be assigned by the Company
                  except to an affiliate of the Company, provided, however, that
                  if the Company shall merge or effect a share exchange with or
                  into, or sell or otherwise transfer substantially all its
                  assets to, another corporation, the Company shall assign its
                  rights hereunder to that corporation and cause such
                  corporation to assume the Company's obligations under this
                  Agreement.

                  13. Notices. Any notice or other communications under this
Agreement shall be in writing, signed by the party making the same, and shall be

         SECTION 2.01.  The Committed Rate Advances.

         (a) Each Bank severally agrees, on the terms and conditions hereinafter
set forth, to make Committed Rate Advances to the Borrower from time to time on
any Business Day during the period from the Closing Date until the Revolver
Termination Date, in an amount for each such Advance not to exceed such Bank's

not be obligated to make such Committed Rate Advance if, after giving effect to
such Committed Rate Advance and the other Committed Rate Advances to be made by
the other Banks as part of the same Borrowing, the then outstanding aggregate
principal amount of all Committed Rate Advances shall exceed the aggregate
Commitments of the Banks less the then outstanding aggregate principal amount of

Percentage (the "Competitive Bid Reduction"). Each Committed Rate Borrowing

<PAGE>   30

         (b) Each Committed Rate Borrowing shall be made on notice, given not
later than 11:00 A.M. (New York City time) (i) on the second Business Day prior
to the date of the proposed Borrowing, in the case of Eurodollar Rate Advances,
and (ii) on the date of the proposed Borrowing, in the case of Base Rate
Advances, by the Borrower to the Agent, which shall give each Bank prompt notice
thereof by telecopier, telex or cable. Each such notice of a Borrowing (a
"Notice of Borrowing") shall be by telecopier, telex or cable, confirmed
immediately in writing, in substantially the form of Exhibit B-1 hereto,
specifying therein (i) the requested date of such Borrowing, (ii) the requested
Type of Advances comprising such Borrowing, (iii) the requested aggregate amount
of such Borrowing, and (iv) in the case of a Borrowing comprised of Eurodollar
Rate Advances, the requested initial Interest Period for each such Advance. Each
Bank shall, before 12:00 noon (New York City time) on the date of such
Borrowing, make available for the account of its Applicable Lending Office to
the Agent at its address referred to in Section 8.02, in same day funds, such
Bank's ratable portion of such Borrowing. After the Agent's receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article
III, the Agent will make such funds available to the Borrower at the Agent's
aforesaid address. Anything in this subsection (b) above to the contrary
notwithstanding, (A) the Borrower may not select Eurodollar Rate Advances for
any Committed Rate Borrowing if the obligation of the Banks to make Eurodollar
Rate Advances shall then be suspended pursuant to Section 2.11 and (B) no more
than eight Committed Rate Borrowings consisting of Eurodollar Rate Advances may
be outstanding at any one time.

         (c) Each Notice of Borrowing shall be irrevocable and binding on the
Borrower. In the case of any Committed Rate Borrowing which the related Notice
of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the
Borrower shall indemnify each Bank against any loss (including loss of
anticipated profits), cost or expense incurred by such Bank as a result of any
failure to fulfill on or before the date specified in such Notice of Borrowing
for such Borrowing the applicable conditions set forth in Article III,
including, without limitation, any loss, cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such Bank
to fund the Advance to be made by such Bank as part of such Borrowing when such
Advance, as a result of such failure, is not made on such date.

         (d) Unless the Agent shall have received notice from a Bank prior to
the date of any Committed Rate Borrowing that such Bank will not make available
to the Agent such Bank's ratable portion of such Borrowing, the Agent may assume
that such Bank has made such portion available to the Agent on the date of such
Borrowing in accordance with subsection (b) above and the Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such ratable portion available to the Agent, such Bank and the Borrower
severally agree to repay to the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount is
made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Advances comprising such Borrowing and (ii) in the case of such Bank,
the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding
amount, such amount so repaid shall constitute such Bank's Advance as part of
such Borrowing for purposes of this Agreement. To 


                                       25
<PAGE>   31

the extent that any Bank makes a payment of principal or interest to the Agent
pursuant to this subsection (d), the Borrower shall not be obligated to make
such payment.

         (e) The failure of any Bank to make the Advance to be made by it as
part of any Committed Rate Borrowing shall not relieve any other Bank of its
obligation, if any, hereunder to make its Advance on the date of such Borrowing,
but no Bank shall be responsible for the failure of any other Bank to make the
Advance to be made by such other Bank on the date of any Committed Rate
Borrowing.

         (a) Each Designated Bidder severally agrees, on the terms and

amount of Competitive Bid Advances made on any Business Day may not exceed the
aggregate Unused Commitments of the Banks on such Business Day and the then
outstanding principal amount of any other Competitive Bid Advances; provided
further that Competitive Bid Advances may not be made while there are any Unused
Commitments (as defined in the $250,000,000 Credit Agreement) other than in

$250,000,000 Credit Agreement).

         but may not exceed the principal amount of the Competitive Bid Advances

provided that if the Agent in its capacity as a Designated Bidder shall, in its
sole discretion, elect to make any such Competitive Bid, it shall notify the
Borrower of such Competitive Bid before 9:30 A.M. (New York City time) on the
Bid Due Date. If any Designated Bidder shall elect not to make such a
Competitive Bid, such Designated Bidder shall so notify the Agent, before 10:00
A.M. (New York City time) on the Bid Due Date, and such Designated Bidder shall
not be obligated to, and shall not, make any Advance as part of such Competitive
Bid Borrowing; provided that the failure by any Designated Bidder to give such
notice shall not cause such Designated Bidder to be obligated to make any
Advance as part of such proposed Competitive Bid Borrowing. Unless otherwise
agreed by the Borrower and the Agent, no Competitive Bid shall contain
qualifying, conditional or similar language or propose terms other than or in
addition to those set forth in the Competitive Bid Request and, in particular,
no Competitive Bid may be conditioned upon acceptance by the Borrower of all (or
some specified minimum) of the principal amount of the Competitive Bid Advances
offered.

         (d) The Agent shall, as promptly as practicable after the Competitive
Bid is submitted (but in any event not later than 10:15 A.M. (New York City
time) on the Bid Due Date), notify the Borrower of the terms (A) of any
Competitive Bid submitted that is in accordance with subsection (c) above and
(B) of any Competitive Bid that amends, modifies or is otherwise inconsistent
with a previous Competitive Bid with respect to the same Competitive Bid
Request. Any such subsequent Competitive Bid may be submitted solely to correct
a manifest error in such former Competitive Bid. The Agent's notice to the
Borrower shall specify (1) the aggregate principal amount of the Competitive Bid
Borrowing for which Competitive Bids have been received and (2) the respective
principal amounts and the Fixed Rates and LIBOR Margins, as



                                       27
<PAGE>   33

the case may be, so offered by each Designated Bidder (identifying the
Designated Bidder that made each Competitive Bid).

         (e) The Borrower shall, in turn, before 11:00 A.M. (New York City time)
(i) on the day of the proposed Competitive Bid Borrowing, in the case of
requests for Fixed Rate Advances, or (ii) on the third Business Day prior to the
date of the proposed Competitive Bid Advances, in the case of a request for
LIBOR Advances, (or, in any such case, such other time and date as the Borrower
and the Agent, with the consent of the Majority Banks, may agree), either:

             (i) cancel such Competitive Bid Borrowing by giving the Agent
         notice to that effect, or

             (ii) accept one or more of the Competitive Bids, in its sole
         discretion, by giving notice to the Agent of the amount of each
         Competitive Bid Advance to be made by each Designated Bidder as part of
         such Competitive Bid Borrowing, and reject any remaining Competitive
         Bids by giving the Agent notice to that effect; provided that (A) the
         Borrower may only accept Competitive Bids in the order of the lowest to
         the highest Fixed Rates or LIBOR Margins, as the case may be, offered,
         (B) the Borrower may not accept Competitive Bids in excess of the
         amount requested pursuant to subsection (b) above, or the amount
         offered pursuant to subsection (c) above, for any maturity date or
         Interest Period, and (C) if two or more Designated Bidders make
         Competitive Bids at the same Fixed Rates or LIBOR Margins, as the case
         may be, for the same maturity date or Interest Period, the Borrower may
         only accept such Competitive Bids in proportion (as nearly as possible)
         to the amounts which such Designated Bidders offered at such rate for
         such maturity or Interest Period (in amounts of not less than
         $1,000,000 or an integral multiple of $100,000 in excess thereof).

         (f) If the Borrower notifies the Agent that such Competitive Bid
Borrowing is canceled pursuant to subsection (d)(i) above, the Agent shall give
prompt notice thereof to the Designated Bidders, and such Competitive Bid
Borrowing shall not be made.

         (g) If the Borrower accepts one or more of the Competitive Bids made by
any Designated Bidder or Designated Bidders pursuant to subsection (d)(ii)
above, the Agent shall in turn promptly notify (A) each Designated Bidder that
has made a Competitive Bid as described in subsection (c) above, of the date and
aggregate amount of such Competitive Bid Borrowing and whether or not any
Competitive Bid or Bids made by such Designated Bidder pursuant to subsection
(c) above have been accepted by the Borrower, (B) each Designated Bidder that is
to make an Advance as part of such Competitive Bid Borrowing, of the amount of
each Advance to be made by such Bank as part of such Borrowing, and (C) each
Designated Bidder that is to make an Advance as part of such Competitive Bid
Borrowing, as to whether such Competitive Bid Borrowing conforms of the
requirements of Section 2.02. Each Designated Bidder that is to make an Advance
as part of such Competitive Bid Borrowing shall, before 11:30 A.M. (New York
City time) on the date of such Competitive Bid Borrowing specified in the notice
received from the Agent pursuant to clause (A) of the preceding sentence
(provided such Designated


                                       28
<PAGE>   34

Bidder shall have received a Competitive Bid Note and a favorable notice from
the Agent pursuant to clause (C) of the preceding sentence), make available to
the Agent at its address referred to in Section 8.02, in same day funds, such
Designated Bidder's portion of such Competitive Bid Borrowing. Upon fulfillment
of the applicable conditions set forth in Article III and after receipt by the
Agent of such funds, the Agent will make such funds available to the Borrower at
the Agent's aforesaid address. Promptly after each Competitive Bid Borrowing,
the Agent shall notify each Bank of the amount of the Competitive Bid Borrowing,
the consequent Competitive Bid Reduction and the dates upon which such
Competitive Bid Reduction commenced and will terminate.

         (h) Each Competitive Bid Borrowing shall be in an aggregate amount not
less than $3,000,000 or an integral multiple of $1,000,000 in excess thereof
and, following the making of such Competitive Bid Borrowing, the Borrower shall
be in compliance with the limitations set forth in the proviso to the first
sentence of subsection (a) above.

         (i) Each acceptance by Borrower pursuant to subsection (g) above shall
be irrevocable and binding on the Borrower. In the case of any acceptance of a
Competitive Bid for LIBOR Advances, the Borrower shall indemnify each Designated
Bidder against any loss (including loss of anticipated profits), cost or expense
incurred by such Designated Bidder as a result of any failure to fulfill on or
before the date specified pursuant to subsection (g) above for such Competitive
Bid Borrowing the applicable conditions set forth in Article III, including,
without limitation, any loss, cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such
Designated Bidder to fund the LIBOR Advance to be made by such Bank as part of
such Borrowing when such Advance, as a result of such failure, is not made on
such date.

         (j) The failure of any Designated Bidder to make the Advance to be made
by it as part of any Competitive Bid Borrowing shall not relieve any other
Designated Bidder of its obligation, if any, hereunder to make its Advance on
the date of such Borrowing, but no Designated Bidder shall be responsible for
the failure of any other Designated Bidder to make the Advance to be made by
such other Designated Bidder on the date of any Competitive Bid Borrowing.

         (k) Within the limits and on the conditions set forth in this Section
2.02, the Borrower may from time to time borrow under this Section 2.02, repay
pursuant to Section 2.05 and reborrow under this Section 2.02; provided that not
more than ten Competitive Bid Borrowings may be outstanding at any time (for
which purpose Competitive Bid Advances made on the same date, but having
different maturities or representing Borrowings under different Commitments,
shall be deemed to be separate Competitive Bid Borrowings).

         SECTION 2.03.  Fees.

         (a) Facility Fees. The Borrower agrees to pay to the Agent, for the
account of each of the Banks, a facility fee on the average daily Commitment of
such Bank from the Closing Date until the Revolver Termination Date at the
Applicable Facility Fee Rate from time to time in 



                                       29
<PAGE>   35

effect, payable quarterly in arrears on the last day of September and December
1997 and March 1998 and on the Revolver Termination Date.

         (b) Agency, Auction and Arrangement Fees. The Borrower agrees to pay to
the Agent, for its own account, the agency fees and the auction fees and to an
Affiliate of the Agent, the arrangement fee, in such amounts and on such dates
as are specified in the letter agreement dated as of June 2, 1997, between the
Borrower and the Agent.

         SECTION 2.04. Optional Reduction of the Commitments. The Borrower shall
have the right, upon at least three Business Days' notice to the Agent,
permanently to terminate in whole or reduce ratably in part the Unused
Commitments; provided that (a) each partial reduction shall be in the aggregate
amount of $3,000,000 or an integral $1,000,000 multiple in excess thereof, (b)
each reduction shall be made ratably among the Banks in accordance with their
Unused Commitments, and (c) no reduction may reduce the aggregate Commitments of
the Banks below the aggregate amount of the then outstanding principal amount of
the Competitive Bid Advances.

         SECTION 2.05.  Repayment.

         (a) The Borrower shall repay on the Revolver Termination Date the
aggregate principal amount of the Committed Rate Advances of each Bank
outstanding on the Revolver Termination Date, together with accrued interest
thereon.

         (b) The Borrower shall repay the aggregate principal amount of the
Competitive Bid Advances of each Designated Bidder, together with accrued
interest thereon, in such amounts and on such dates as specified pursuant to
Section 2.02(b).

         SECTION 2.06.  Interest.

         (a) The Borrower shall pay interest on the unpaid principal amount of
each Committed Rate Advance made by each Bank from the date of such Advance
until such principal amount shall be paid in full, at the following rates per
annum:

             (i) Base Rate Advances. During such periods as such Advance is a 
         Base Rate Advance, a rate per annum equal at all times to the sum
         of the Base Rate in effect from time to time, payable quarterly in
         arrears on the last day of each March, June, September and December
         during such periods and on the date such Base Rate Advance shall be
         Converted or paid in full. Notwithstanding the foregoing, during the
         continuance of an Event of Default, the principal amount of each Base
         Rate Advance shall bear interest, to the fullest extent permitted by
         law, from the date on which such amount is due until such amount is
         paid in full, payable on demand, at a fluctuating rate per annum equal
         at all times to 2% per annum above the Base Rate in effect from time to
         time.

             (ii) Eurodollar Rate Advances. During such periods as such Advance 
         is a Eurodollar Rate Advance, a rate per annum equal at all times 
         during the Interest Period for such Advance to the sum of the 
         Eurodollar Rate for such Interest Period plus the Applicable Eurodollar
         Rate Margin, payable on the last day of such Interest Period and, if


                                       30
<PAGE>   36


         such Interest Period has a duration of six months, on the day that
         occurs during such Interest Period three months from the first day of
         such Interest Period; provided, however, that in the event that the
         Applicable Eurodollar Rate Margin for any fiscal quarter of the
         Borrower has not yet been determined in accordance with the provisions
         of the definition of Applicable Eurodollar Rate Margin in Section 1.01
         as of the time when interest on a Eurodollar Rate Advance becomes due,
         the Borrower shall pay such interest on the date when due based on the
         then existing Applicable Eurodollar Rate Margin and any necessary
         subsequent adjustments in the amount of interest payable hereunder (due
         to any subsequent change in the Applicable Eurodollar Rate Margin)
         shall be made on the first date on which any interest on any Committed
         Rate Advance is payable after the date of determination of the
         Applicable Eurodollar Rate Margin. Notwithstanding the foregoing,
         during the continuance of an Event of Default, the principal amount of
         each Eurodollar Rate Advance shall bear interest, to the fullest extent
         permitted by law, from the date on which such amount is due until such
         amount is paid in full, payable on demand, at a rate per annum equal at
         all times to 2% per annum above the Eurodollar Rate plus the Applicable
         Eurodollar Rate Margin until the end of the Interest Period applicable
         to such Eurodollar Rate Advance, at which time the rate per annum shall
         become 2% per annum above the Base Rate, in each case as in effect from
         time to time.

         (b) The Borrower shall pay interest on the unpaid principal amount of
each Competitive Bid Advance from the date of such Advance until such principal
amount shall be paid in full, at the rate of interest for such Advance specified
by the Designated Bidder making such Advance in its Competitive Bid with respect
thereto delivered pursuant to Section 2.02(c), payable on the interest payment
date or dates specified by the Borrower for such Advance in the related
Competitive Bid Request delivered pursuant to Section 2.02(b) and on the
maturity date of such Competitive Bid Advance. Notwithstanding the foregoing,
during the continuance of an Event of Default, the principal amount of each
Competitive Bid Advance shall bear interest, to the fullest extent permitted by
law, from the date on which such amount is due until such amount is paid in
full, payable on demand, at a rate equal to 2% per annum above the interest rate
specified by the Designated Bidder that made such Advance in its Competitive Bid
with respect thereto delivered pursuant to Section 2.02(c).

         SECTION 2.07.  Interest Rate Determination and Protection.

         (a) The Agent shall give prompt notice to the Borrower and the Banks of
the applicable interest rate under Section 2.06(a)(i) or (ii).

         (b) If, with respect to any Eurodollar Rate Advance, the Majority Banks
notify the Agent that the Eurodollar Rate for any Interest Period for such
Advance will not adequately reflect the cost to such Majority Banks of making,
funding or maintaining their respective Eurodollar Rate Advance for such
Interest Period, the Agent shall forthwith so notify the Borrower and the Banks,
whereupon:
             
             (i) each Eurodollar Rate Advance will automatically, on the last 
         day of the then existing Interest Period therefor, Convert into a
         Base Rate Advance, and

                                       31
<PAGE>   37

             (ii) the obligation of the Banks to make, or to Convert Advances 
         into, Eurodollar Rate Advances shall be suspended until the Agent 
         shall notify the Borrower and the Banks that the circumstances causing 
         such suspension no longer exist.

         (c) If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advance in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the Agent will
forthwith so notify the Borrower and the Banks and such Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into Base Rate Advances.

         SECTION 2.08. Voluntary and Automatic Conversion of Committed Rate
Advances.

         (a) The Borrower may on any Business Day, upon notice given to the
Agent not later than 11:00 A.M. (New York City time) on the second Business Day
prior to the date of the proposed Conversion and subject to the provisions of
Sections 2.07 and 2.11, Convert all Committed Rate Advances of one Type
comprising the same Borrowing into Committed Rate Advances of another Type;
provided, however, that any Conversion of any Eurodollar Rate Advances into Base
Rate Advances shall be made on, and only on, the last day of an Interest Period
for such Eurodollar Rate Advances. Each such notice of Conversion shall, within
the restrictions specified above, specify (i) the date of such Conversion, (ii)
the Advances to be Converted, and (iii) if such Conversion is into Eurodollar
Rate Advances, the duration of the Interest Period for each such Advance.

         (b) On the date on which the unpaid aggregate principal amount of
Eurodollar Rate Advances comprising any Committed Rate Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $3,000,000, the
Eurodollar Rate Advances comprising such Borrowing shall automatically Convert
into Base Rate Advances, and on and after such date the Borrower may not convert
such Base Rate Advances to Eurodollar Rate Advances until such time as the
aggregate principal amount of Base Rate Advances equals or exceeds $3,000,000.

         SECTION 2.09.  Prepayments.

         (a) Voluntary Prepayments. The Borrower may, upon at least (i) in the
case of Eurodollar Rate Advances, two Business Days' and (ii) in the case of
Base Rate Advances, the same Business Day's notice to the Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such
notice is given, the Borrower shall, prepay the outstanding principal amounts of
the Advances comprising part of the same Committed Rate Borrowing in whole or
ratably in part, together with accrued interest to the date of such prepayment
on the principal amount prepaid and, in the case of Eurodollar Rate Advances,
any amounts payable under Section 8.04(b); provided, however, that each partial
prepayment shall be in an aggregate principal amount not less than $3,000,000 or
any integral multiple of $1,000,000 in excess thereof. The Borrower may not
prepay any Competitive Bid Advances.

         (b) Asset Sales Mandatory Prepayments. Subject to Section 2.09(f), upon
the sale, lease or other disposition by the Borrower or any Subsidiary of the
Borrower of assets of the Borrower and its Subsidiaries constituting more than
5% of the Consolidated Total Assets of the 



                                       32
<PAGE>   38

Borrower and its Subsidiaries at the time of sale, lease or other disposition,
then (x) the Net Cash Proceeds of such sale, lease or other disposition shall be
delivered as soon as practicable to the Agent and (y) any deferred cash proceeds
of such sale, lease, or other disposition shall be delivered to the Agent as
soon as practicable after their receipt (at which time the same shall become Net
Cash Proceeds). Any such Net Cash Proceeds shall be applied in accordance with
Section 2.09(e).

         (c) Subordinated Debt Issuance Mandatory Prepayments. Subject to
Section 2.09(f), upon the issuance, if permitted in writing by the Majority
Banks, by the Borrower or any of its Subsidiaries of any Subordinated Debt,
whether or not convertible into or exchangeable for Securities (other than the
subordinated convertible notes issued by the Borrower or any of its Subsidiaries
as consideration for the acquisition of Facilities (or the assets thereof), any
Existing Clinic Acquisitions or the acquisition of Related Businesses), then (x)
75% of the Net Cash Proceeds of such issuance shall be delivered as soon as
practicable to the Agent and (y) 75% of any deferred cash proceeds of such
issuance shall be delivered to the Agent as soon as practicable after their
receipt (at which time the same shall become Net Cash Proceeds). Any such Net
Cash Proceeds shall be applied in accordance with Section 2.09(e).

         (d) Securities Issuance Mandatory Prepayment. Subject to Section
2.09(f), upon the sale or issuance by the Borrower or any of its Subsidiaries of
any Securities, any securities convertible into or exchangeable for Securities
(other than Subordinated Debt subject to Section 2.09(c)), or any warrants,
rights or options to acquire Securities to any Person other than the Borrower or
any of its Subsidiaries other than such sale or issuance pursuant to the
Borrower's employee stock purchase plans or employee and director stock option
plans or similar plan available to physicians practicing at a Facility or
Related Business and other than the issuance of Securities as consideration for,
or the proceeds of which are within 180 days after receipt used for, or the
issuance of subordinated convertible notes as consideration for, the acquisition
of any Facility (or the assets thereof) or any Existing Clinic Acquisitions or
the acquisition of any Related Businesses to the extent such acquisition
satisfies all the requirements of Section 5.02(f)(i) or (ii), as the case may
be), then (x) 50% of the Net Cash Proceeds of such sale or issuance shall be
delivered as soon as practicable to the Agent and (y) 50% of any deferred cash
proceeds of such sale or issuance shall be delivered to the Agent as soon as
practicable after their receipt (at which time the same shall become Net Cash
Proceeds). Any such Net Cash Proceeds shall be applied in accordance with
Section 2.09(e).

         (e) Application of Prepayments. Mandatory prepayments pursuant to
Section 2.09(b), (c) or (d) shall be: first, applied to the payment of any
amount then owing to the Agent or any Bank pursuant to Section 8.04(a); second,
applied to the ratable payment of outstanding Committed Rate Advances, together
with accrued interest to the date of such payment on the principal amount repaid
and any amounts payable pursuant to Section 8.04(b) in respect thereof; and
third, delivered to the Agent to be held as pledged collateral to be applied to
the ratable payment when due of outstanding Competitive Bid Advances, together
with accrued interest to the date of such payment on the principal amount
repaid, to the extent of the aggregate amount of such principal and interest.


                                       33
<PAGE>   39

         (f) Effect of Investment Grade Rating. Notwithstanding Sections
2.09(b), (c), (d) or (e), no prepayment shall be required by any of such
sections if at the time of the sale, lease or other disposition, issuance or
sale referred to therein any of the then outstanding Debt of the Borrower shall
then be rated Investment Grade.

         SECTION 2.10.  Increased Costs.

         (a) If, due to either (i) the introduction of or any change (other than
any change by way of imposition or increase of reserve requirements, in the case
of Eurodollar Rate Advances or LIBOR Advances, included in the Eurodollar Rate
Reserve Percentage) in or in the interpretation of any law or regulation or (ii)
the compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be
any increase in the cost to any Bank of agreeing to make or making, funding or
maintaining Eurodollar Rate Advances or LIBOR Advances, then the Borrower shall
from time to time, upon demand by such Bank (with a copy of such demand to the
Agent), pay to the Agent for the account of such Bank additional amounts
sufficient to compensate such Bank for such increased cost. A certificate as to
the amount of such increased cost, submitted to the Borrower and the Agent by
such Bank, shall be conclusive and binding for all purposes, absent manifest
error.

         (b) If any Bank determines that compliance with any law or regulation
or any guideline or request from any central bank or other governmental
authority (whether or not having the force of law) affects or would affect the
amount of capital (or the rate of return on capital) required or expected to be
maintained by such Bank or any corporation controlling such Bank and that the
amount of such capital is increased (or such rate of return is reduced) by or
based upon the existence of such Bank's commitment, or offer or agreement, to
lend hereunder and other commitments, or offers or agreements, of this type,
then, upon notice by such Bank (with a copy of such notice to the Agent), the
Borrower shall immediately pay to the Agent for the account of such Bank, from
time to time as specified by such Bank, additional amounts sufficient to
compensate such Bank or such corporation in the light of such circumstances, to
the extent that such Bank reasonably determines such increase in capital (or
reduction in rate of return) to be allocable to the existence of such Bank's
commitment, or offer or agreement, to lend hereunder. Such notice as to such
amounts submitted and delivered to the Borrower and the Agent by such Bank shall
set forth in summary fashion the basis of such allocation and shall be
conclusive and binding for all purposes, absent manifest error.

         SECTION 2.11. Illegality. Notwithstanding any other provision of this
Agreement, if any Bank shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful,
or any central bank or other governmental authority asserts that it is unlawful,
for any Bank or its Eurodollar Lending Office to perform its obligations or
agreements hereunder to make Eurodollar Rate Advances or LIBOR Advances or to
fund or maintain Eurodollar Rate Advances or LIBOR Advances hereunder: (a) in
the case of Eurodollar Rate Advances, (i) the obligation of the Banks to make,
or to Convert Advances into, Eurodollar Rate Advances shall be suspended until
the Agent shall notify the Borrower and the Banks that the circumstances causing
such suspension no longer exist and (ii) the Borrower shall 


                                       34
<PAGE>   40

forthwith prepay in full all Eurodollar Rate Advances of all Banks then
outstanding, together with interest accrued thereon and any costs payable
pursuant to Section 8.04(b), unless the Borrower, within five Business Days of
notice from the Agent, Converts all Eurodollar Rate Advances of all Banks then
outstanding into Base Rate Advances in accordance with Section 2.08, and (b) in
the case of LIBOR Advances, such Bank shall no longer be obligated to fund any
LIBOR Advance it has agreed to fund thereafter.

         SECTION 2.12.  Payments and Computations.

         (a) The Borrower shall make each payment hereunder and under the Notes
not later than 11:00 A.M. (New York City time) on the day when due free and
clear of any taxes, offset or other charge in United States dollars to the Agent
at its address referred to in Section 8.02 in same day funds. The Agent will
promptly thereafter cause to be distributed like funds relating to the payment
of principal or interest or facility fees (i) ratably (other than amounts
payable pursuant to Section 2.10, 2.13 or 8.04) to the Banks for the account of
their respective Applicable Lending Offices, in the case of Committed Rate
Advances, and to the applicable Designated Bidder (for the account of its
Applicable Lending Office), in the case of Competitive Bid Advances, and like
funds relating to the payment of any other amount payable to any Bank to such
Bank for the account of its Applicable Lending Office, in each case to be
applied in accordance with the terms of this Agreement. Upon its acceptance of
an Assignment and Acceptance and recording of the information contained therein
in the Register pursuant to Section 8.08(d), from and after the effective date
specified in such Assignment and Acceptance, the Agent shall make all payments
hereunder in respect of the interest assigned thereby to the Bank assignee
thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

         (b) The Borrower hereby authorizes each Bank, if and to the extent
payment owed to such Bank is not made when due hereunder or under the Note held
by such Bank, to charge from time to time against any or all of the Borrower's
accounts with such Bank any amount so due.

         (c) All computations of interest (other than interest on Base Rate
Advances) and of fees shall be made on the basis of a year of 360 days, and all
computations of interest on Base Rate Advances shall be made on the basis of a
year of 365 or 366 days (as the case may be), in each case for the actual number
of days (including the first day but excluding the last day) occurring in the
period for which such interest or fees are payable. Each determination by the
Agent of an interest rate or fee hereunder shall be conclusive and binding for
all purposes, absent manifest error.

         (d) Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or facility fee, as the case
may be; provided, however, if such extension would cause payment of interest on
or principal of Eurodollar Rate Advances or LIBOR Advances to be made 

                                       35

<PAGE>   41

in the next following calendar month, such payment shall be made on the next
preceding Business Day.

         (e) Unless the Agent shall have received notice from the Borrower prior
to the date on which any payment is due to the Banks hereunder in respect of
Committed Rate Advances that the Borrower will not make such payment in full,
the Agent may assume that the Borrower has made such payment in full to the
Agent on such date and the Agent may, in reliance upon such assumption, cause to
be distributed to each Bank on such due date an amount equal to the amount then
due such Bank. If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Bank shall repay to the Agent forthwith on
demand such amount distributed to such Bank together with interest thereon, for
each day from the date such amount is distributed to such Bank until the date
such Bank repays such amount to the Agent, at the Federal Funds Rate.

         (f) Notwithstanding any provision in this Agreement or any other Loan
Document to the contrary, all payments received by the Agent under the other
Loan Documents, the application of which are not provided for in such Loan
Documents, may be then or at any time thereafter be applied in whole or in part
by the Agent for the ratable benefit of the Banks (except in the case of
Competitive Bid Advances), against all or part of the Advances or other
obligations of the Borrower hereunder or under the other Loan Documents, in such
order and manner as the Agent shall elect.

         SECTION 2.13.  Taxes.

         (a) Any and all payments by the Borrower hereunder or under the Notes
shall be made, in accordance with Section 2.12, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding, in
the case of each Bank and the Agent, taxes imposed on its income, and franchise
taxes imposed on it, by the jurisdiction under the laws of which such Bank or
the Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Bank, taxes imposed on its income, and franchise taxes
imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or
any political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note to any Bank or the
Agent, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 2.13) such Bank or the Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

         (b) In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or under the Notes or from
the execution, delivery or 


                                       36
<PAGE>   42

registration of, or otherwise with respect to, this Agreement or the Notes
(hereinafter referred to as "Other Taxes").

         (c) The Borrower will indemnify each Bank and the Agent for the full
amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
2.13) paid by such Bank or the Agent (as the case may be) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. This indemnification shall be made within 30 days from the date such
Bank or the Agent (as the case may be) makes written demand therefor.

         (d) Within 30 days after the date of any payment of Taxes, the Borrower
will furnish to the Agent, at its address referred to in Section 8.02, the
original or a certified copy of a receipt evidencing payment thereof.

         (e) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.13 shall survive the payment in full of principal and interest
hereunder and under the Notes.

         (f) Prior to the date of the first Borrowing under this Agreement in
the case of each Bank party hereto on the date hereof, on the date of the
effectiveness of the Assignment and Acceptance pursuant to which it became a
Bank in the case of each other Bank, and within 30 days following the first day
of each calendar year or if otherwise requested from time to time by the
Borrower or the Agent, each Bank organized under the laws of a jurisdiction
outside the United States shall provide the Agent and the Borrower with two
counterparts of each of the forms prescribed by the Internal Revenue Service
(Form 1001 or 4224, or successor form(s), as the case may be, or another
appropriate form) of the United States certifying as to such Bank's status for
purposes of determining exemption from United States withholding taxes with
respect to all payments to be made to such Bank under any Loan Document. Unless
the Borrower and the Agent have received such forms or other documents
satisfactory to them indicating that payments under any Loan Document are not
subject to United States withholding tax, the Borrower or the Agent (if not
withheld by the Borrower) shall withhold taxes from such payments at the
applicable statutory rate, without any obligation to "gross-up" or make such
Bank or the Agent whole under Section 2.13(a); provided, however, that the
Borrower shall have the obligation to make such Bank or the Agent whole and to
"gross-up" under Section 2.13(a), if the failure to so deliver such forms or
make such statements (other than the forms and statements required to be
delivered on or made prior to the date of the initial Borrowing, on the date of
the Assignment and Acceptance pursuant to which an Eligible Assignee became a
Bank) is the result of the occurrence of an event (including, without
limitation, any change in treaty, law or regulation) which (alone or in
conjunction with other events) renders such forms inapplicable, that would
prevent such Bank or the Agent from making the statements contemplated by such
forms or which removes or reduces an exemption (whether partial or complete)
from withholding tax previously available to such Bank or the Agent. Each Bank
(and the Agent, if applicable) will promptly notify the Borrower of the
occurrence (when known to it) of an event contemplated by the foregoing proviso.

         SECTION 2.14. Sharing of Payments. Etc. If any Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of any Committed Rate Advances made by it
(other than pursuant to Section 2.10, 2.13 or 8.04) in excess of its ratable
share of payments on account of such Committed Rate Advances obtained by all the
Banks, such Bank shall forthwith purchase from the other Banks such
participations in such Committed Rate Advances made by them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Bank, such purchase from
each Bank shall be rescinded and such Bank shall repay to the purchasing Bank
the purchase price to the extent of such recovery together with an amount equal
to such Bank's ratable share (according to the proportion of (i) the amount of
such Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. The Borrower agrees
that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.14 may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off) with respect to such
participation as fully as if such Bank were the direct creditor of the Borrower
in the amount of such participation.

         SECTION 2.15.  Evidence of Debt/Register.

         (a) The Debt of the Borrower resulting from the Committed Rate Advances
and Competitive Bid Advances shall be evidenced by the Committed Rate Notes and
the Competitive Bid Notes, respectively, delivered to the Banks pursuant to
Article III, and the remaining principal amount thereof shall be recorded by the
Banks, and, prior to any transfer, endorsed on the grids thereto in accordance
with the terms of the Notes. The Agent shall also maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the
Borrower under this Agreement and the amounts of principal and interest payable
and paid to each Bank from time to time under this Agreement.

         (b) The Register maintained by the Agent pursuant to Section 8.08(c)
shall include a control account, and a subsidiary account for each Bank, in
which accounts (taken together) shall be recorded: (i) the date and amount of
each Borrowing, the Commitment to which such Borrowing relates, the Type of
Advance comprising such Borrowing and the Interest Period applicable thereto (if
any) from time to time, (ii) the terms of each Assignment and Acceptance
delivered to and accepted by it, (iii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Bank, and
(iv) the amount of any sum received by the Agent from the Borrower hereunder and
each Bank's share thereof.

         SECTION 2.16. Use of Proceeds. The proceeds of the Advances shall be
used by the Borrower for Capital Investments (to the extent permitted under this
Agreement), including, without limitation, acquisitions of Facilities and
Related Businesses (to the extent permitted under this Agreement), and other
general corporate purposes.

                        Collateral

         (a) Existing Credit Agreement B Advances, Termination of B Commitment
Under Existing Credit Agreement. On the Closing Date: (i) there shall be no
outstanding B Advances (as defined in the Existing Credit Agreement) and (ii)
the B Commitments (as such term is defined in the Existing Credit Agreement)
shall be permanently terminated in full.

         (b) Release of Collateral. On the Closing Date, all Liens on the
Collateral (as defined in the Existing Credit Agreement) shall be released and
terminated, and from and after the Closing Date, the Agent shall execute and
deliver, at the Borrower's expense, such termination statements and other
documents as the Borrower may reasonably request to evidence the release and
termination of such Liens.

statements shall be true and the Agent shall have received a certificate signed
by a duly authorized officer of the Borrower, dated the date of such Borrowing,

         both;

and (b) the Competitive Bid Note, duly executed by the Borrower, to the order of
the appropriate Designated Bidder, shall have been received by the Agent, and

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         SECTION 4.01. Representations and Warranties of the Borrower. The
Borrower represents and warrants as follows:

                  (a) The Borrower is a corporation duly incorporated, validly
         existing and in good standing under the laws of its jurisdiction of
         incorporation, is duly qualified as a foreign corporation and is in
         good standing in each jurisdiction as to which the location of its
         assets or the nature of its business makes qualification necessary, and
         has all power, corporate or otherwise, to conduct its business and to
         own, or hold under lease, its assets, and to execute and deliver, and
         to perform all of its obligations under, each of the Loan Documents to
         which it is or will be a party. Each of the Borrower's Subsidiaries
         other than Immaterial Subsidiaries is a corporation, limited liability
         company or partnership duly organized, validly existing and in good
         standing under the laws of its respective jurisdiction of organization,
         is duly qualified as a foreign corporation, limited liability company
         or partnership and is in good standing in each jurisdiction as to which
         the location of its assets or the nature of its business makes
         qualification necessary, and has all power (corporate, limited
         liability company, partnership or otherwise) to conduct its business
         and to own, or hold under lease, its assets, and to execute and
         deliver, and to 

                                       41
<PAGE>   47

         perform all of its obligations under, each of the Loan Documents to
         which it is or will be a party.

                  (b) The execution, delivery and performance by each Loan Party
         of each Loan Document to which it is or will be a party are within such
         Loan Party's corporate, limited liability company or partnership
         powers, have been duly authorized by all necessary corporate, limited
         liability company or partnership action, and do not contravene (i) such
         Loan Party's certificate or articles of incorporation, by-laws or other
         constituent instruments, or (ii) any law, rule, regulation (including,
         without limitation, Regulation G, T, U or X of the Board of Governors
         of the Federal Reserve System), order, writ, judgment, injunction,
         decree, determination or award binding on or affecting such Loan Party
         or any of its properties, or (iii) any contractual restriction binding
         on or affecting such Loan Party or any of its properties, and do not
         result in or require the creation of any Lien upon or with respect to
         any of its properties; and no Loan Party is in default in any material
         respect under any such law, rule, regulation, order, writ, judgment,
         injunction, decree, determination, award or restriction.

                  (c) No authorization or approval or other action by, and no
         notice to or filing with, any governmental authority or regulatory body
         is required for the due execution, delivery and performance by any Loan
         Party of any Loan Document to which it is or will be a party except for
         those which have been duly obtained or made and are in full force and
         effect.

                  (d) This Agreement is, and each other Loan Document to which
         each Loan Party will be a party when executed and delivered hereunder
         will be, the legal, valid and binding obligation of such Loan Party
         enforceable against such Loan Party in accordance with its terms.

                  (e) The Consolidated balance sheets of the Borrower and its
         Subsidiaries as at December 31, 1996 and March 31, 1997 and the related
         Consolidated statements of operations, stockholders' equity and cash
         flow of the Borrower and its Subsidiaries for the fiscal year and three
         months, respectively, then ended have been furnished to the Agent. Such
         financial statements, and all financial statements hereafter delivered
         pursuant to Sections 5.04(b) and (c), fairly present, or will fairly
         present, the financial condition of the Borrower and its Subsidiaries
         as at the dates thereof and the results of the operations of the
         Borrower and its Subsidiaries for the periods then ended or ending, all
         in accordance with generally accepted accounting principles
         consistently applied. Since December 31, 1996, there has been no
         material adverse change, in the business, prospects or condition
         (financial or otherwise) or in the results of operations of the
         Borrower and its Subsidiaries taken as a whole.

                  (f) Each Loan Party has good title to all of its material
         property, free and clear of all Liens, except for Permitted Liens. Each
         Lease or other agreement relating to the Real Property described in
         Schedule I operated by each Loan Party is a valid and subsisting Lease
         or other agreement and is in full force and effect in accordance with 
         the


                                       42
<PAGE>   48


         terms thereof; and the Borrower or its Subsidiary is in possession
         of all such leaseholds and no material default by the Borrower or any
         of its Subsidiaries exists under any such Lease or other agreement and,
         to the best of the Borrower's knowledge, no lessor has any accrued
         right to terminate any such Lease or other agreement on account of a

Expenditures or any other component of the ratios referred to in such
subsections (the "Ratio Components") is required to be made as to any period
prior to the date of such determination (a "Determination Period"), such
determination shall be made so as to give effect to the following:

                   (i) if any Person, Facility or Related Business (an "Acquired
         Business") shall have been acquired in compliance with this Agreement

                  arrangements, all of which shall be consistent with the terms
                  and conditions of any Service Agreement entered into in
                  connection with such acquisition and (2) other planned cost
                  savings which will be realized by such Acquired Business as a
                  consequence of such acquisition to the

                  completion of one full fiscal quarter after the date of such
                  acquisition, the actual Ratio Components for the period
                  through the end of the then most recently ended fiscal quarter
                  shall be annualized for the Determination Period; and

                  (ii)     if any Person, Facility or Related Business (a
         "Disposed Business") which shall have been Consolidated with the
         Borrower and its Subsidiaries shall have been discontinued, lost, sold
         or otherwise disposed of as of the date of determination, the Ratio

then, and in any such event, the Agent (i) shall at the request, or may with the
consent, of the Majority Banks, by notice to the Borrower, declare the
obligation of each Bank to make Advances to be terminated, whereupon the same
shall forthwith terminate, (ii) shall at the request, or may with the consent,
of the Majority Banks, by notice to the Borrower, declare the Notes, all
interest thereon and all other amounts payable under this Agreement to be
forthwith due and payable, whereupon the Notes, all such interest and all such

demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Borrower and (iii) shall at the request, or may with the consent,
of the Majority Banks exercise any other remedies provided hereunder or by law;
provided, however, that in the event of an actual or deemed entry of an order
for relief with respect to the Borrower or any of its Subsidiaries under the
Federal Bankruptcy Code, (A) the obligation of each Bank to make Advances shall
automatically be terminated and (B) the Notes, all such interest and all such
amounts shall automatically become and be due and payable, without presentment,
demand, protest or any notice of any kind, all of which are hereby expressly
waived by the Borrower.

                                   ARTICLE VII

                                    THE AGENT

         SECTION 7.01. Authorization and Action. Each Bank hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto. As to
any matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the Notes), the Agent shall not be
required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Majority Banks, and such
instructions shall be binding upon all Banks and all holders of Notes; provided,
however, that the Agent shall not be required to take any action which exposes
the Agent to personal liability or which is contrary to any Loan Document or
applicable law. The Agent agrees to give to each Bank prompt notice of each
notice given to it by the Borrower pursuant to the terms of this Agreement.

         SECTION 7.02. Agent's Reliance, Etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in connection with this Agreement,
except for its or their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent: (i) may treat the
payee of any Note as the holder thereof until the Agent receives written notice
of the assignment or transfer thereof signed by such payee and including the
agreement of the assignee or transferee to be bound hereby as it would have been
if it had been an original Bank party hereto, in form satisfactory to the Agent;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (iii) makes
no warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties or representations (whether written or oral)
made in or in connection with any Loan Document; (iv) shall not have any duty to
ascertain or to inquire as to the performance or observance of any of the terms,
covenants or conditions of any Loan Document on the part of the Borrower or any
Subsidiary of the Borrower or to inspect the property (including the books and
records) of the Borrower or any such Subsidiary; (v) shall not be responsible to
any Bank for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Loan Document or any other instrument or document
furnished pursuant thereto; and (vi) shall incur no liability under or in
respect of any Loan Document by acting upon any notice, consent, certificate or
other instrument or writing (which may be by telecopier, telegram, cable
facsimile or telex) believed by it to be genuine and signed or sent by the
proper party or parties.

         SECTION 7.03. Citibank and Affiliates. With respect to its Commitment,
the Advances made by it and the Notes issued to it, Citibank shall have the same
rights and powers under this Agreement as any other Bank and may exercise the
same as though it were not the Agent; and the term "Bank" or "Banks" shall,
unless otherwise expressly indicated, include Citibank in its individual
capacity. Citibank and its Affiliates may accept deposits from, lend money to,
act as


                                       66
<PAGE>   72

trustee under indentures of, and generally engage in any kind of business
with, the Borrower, any of its Subsidiaries and any Person who may do business
with or own securities of the Borrower or any such Subsidiary, all as if
Citibank were not the Agent and without any duty to account therefor to the
Banks.

         SECTION 7.04. Bank Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank and based on
the financial statements referred to in Section 4.01(e) and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Loan Documents. Each Bank
also acknowledges that it will, independently and without reliance upon the
Agent or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents.

         SECTION 7.05. Indemnification. The Banks agree to indemnify the Agent
(to the extent not reimbursed by the Borrower), ratably according to the
respective principal amounts of the Committed Rate Advances then held by each of
them (or if no Committed Rate Advances are at the time outstanding ratably
according to the respective amounts of their Commitments), from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against the Agent
in any way relating to or arising out of this Agreement or any other Loan
Document or any action taken or omitted by the Agent under this Agreement or any
other Loan Document, provided that no Bank shall be liable 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. Without limitation of the foregoing, each Bank
agrees to reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement to the extent that the Agent is not
reimbursed for such expenses by the Borrower.

         SECTION 7.06. Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Banks and the Borrower and the Agent may be
removed at any time with or without cause by the Majority Banks. Upon any such
resignation or removal, in the case of the Agent, the Majority Banks shall have
the right, subject to the approval of the Borrower (which shall not be
unreasonably withheld), to appoint a successor Agent. If no successor Agent
shall have been so appointed by the Majority Banks, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving of notice of
resignation or the Majority Banks' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Banks, appoint a successor Agent, which
shall be a commercial bank organized under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $100,000,000. Upon the acceptance of any appointment as 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


                                       67
<PAGE>   73

from its duties and obligations under this Agreement and the other Loan
Documents. After any retiring Agent's resignation or removal hereunder as Agent,
the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement and
the other Loan Documents.

         SECTION 7.07.  Documentation Agent.  The Documentation Agent, as such,
shall have no duties or obligations whatsoever with respect to this Agreement, 
the Notes or any of the other Loan Documents.


                                  ARTICLE VIII

                                  MISCELLANEOUS

         SECTION 8.01. Amendments, Etc. No amendment or waiver of any provision
of this Agreement or the Notes or the Loan Documents, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Majority Banks (or consented to in
writing in the case of the Loan Documents), and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, however, that no amendment, waiver or consent shall,
unless in writing and signed by all the Banks, do any of following: (a) waive
any of the conditions specified in Article III, (b) increase the Commitments of
the Banks or subject the Banks to any additional monetary obligations, (c)
reduce the principal of, or interest on, the Committed Rate Advances or the
Committed Rate Notes or any fees or other amounts payable hereunder, (d)
postpone the date fixed for the scheduled payment of principal of, or interest
on, the Committed Rate Advances or the Committed Rate Notes or any fees or other
amounts payable hereunder or waive any such payment when due, (e) change the
percentage of the Commitments or of the aggregate unpaid principal amount of the
Committed Rate Advances or the Committed Rate Notes, or the number or percentage
of Banks, which shall be required for the Banks or any of them to take any
action hereunder or (f) amend this Section 8.01; provided, further, that no
amendment, waiver or consent shall, in writing and signed by the Agent in
addition to the Banks required above to take such action, affect the rights or
duties of the Agent under this Agreement or any Note; and provided also that no
amendment, waiver or consent, unless in writing and signed by the Designated
Bidder holding such Note, affect the rights of the holder of a Competitive Bid
Note under such Note.

         SECTION 8.02. Notices, Etc. All notices and other communications
provided for hereunder shall be in writing (including telecopier, telegraphic,
telex or cable communication) and mailed (by certified mail, return receipt
requested), telecopied, telegraphed, telexed, cabled or delivered, if to the
Borrower, at its address at 30 Burton Hills Blvd., Suite 400, Nashville, TN

telecopier number as shall be designated by such party in a written notice to
the other parties. All such notices and communications shall, when mailed (by

to the telegraph company, confirmed by telex answerback, delivered to the cable
company or confirmed received in the case of a telecopy or facsimile,
respectively, except that notices and communications to the Agent pursuant to
Article II or VII shall not be effective until received by the Agent.

         SECTION 8.03. No Waiver: Remedies. No failure on the part of any Bank
or the Agent to exercise, and no delay in exercising, any right under any Loan
Document shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

         SECTION 8.04.  Costs. Expenses and Taxes.

         (a) The Borrower agrees to pay the Agent on demand all reasonable costs
and expenses of the Agent in connection with the preparation, negotiation,
approval, execution, delivery, filing, recording, administration, modification
and amendment of the Loan Documents and the other documents to be delivered
under the Loan Documents, including, without limitation, the reasonable fees and
out-of-pocket expenses of special and local counsel for the Agent with respect
thereto and with respect to advising the Agent as to its rights and
responsibilities under the Loan Documents and the other documents to be
delivered hereunder and thereunder. The Borrower further agrees to pay on demand
(i) all costs and expenses, if any, of the Agent or any Bank in connection with
the enforcement (whether through negotiations or legal proceedings, in
bankruptcy, reorganization or other insolvency proceedings or otherwise) of the
Loan Documents and the other documents to be delivered under the Loan Documents,
including, without limitation, reasonable counsel fees and expenses in
connection with the enforcement of rights under this Section 8.04(a), and (ii)
all costs and expenses in connection with appraisals, valuations, audits and
search reports, all insurance and title costs, and all filing and recording fees
required hereby or associated with any enforcement of rights or remedies
specified in clause (i).

         (b) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance or LIBOR Advance is made other than on the last day of an Interest
Period relating to such Advance, as a result of a payment (including, without
limitation, any payment pursuant to Section 2.09) or Conversion pursuant to
Section 2.08 or 2.11 or acceleration of the maturity of the Notes pursuant to
Section 6.01 or for any other reason, the Borrower shall, upon demand by any
Bank (with a copy of such demand to the Agent), pay to the Agent for the account
of such Bank any amounts required to compensate such Bank for any additional
losses (including loss of anticipated profits), costs or expenses which it may
reasonably incur as a result of such payment or Conversion, including, without
limitation, any loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Bank to fund or
maintain such Advance.


                                       69
<PAGE>   75

         SECTION 8.05. Right of Set-off. Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the Agent to
declare the Notes due and payable pursuant to the provisions of Section 6.01,
each Bank is hereby authorized at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Bank to or for the credit or the account
of the Borrower against any and all of the obligations of the Borrower now or
hereafter existing under any Loan Document to such Bank, whether or not such
Bank shall have made any demand under this Agreement or such Note and although
such obligations may be unmatured. Each Bank agrees promptly to notify the
Borrower after any such set-off and application made by such Bank, provided that
the failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Bank under this Section 8.05 are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which such Bank may have.

         SECTION 8.06. Indemnification. The Borrower agrees to defend, protect,
indemnify and hold harmless the Agent, each Bank and their respective Affiliates
and the directors, officers, employees, attorneys and agents of the Agent, each
Bank and such Affiliates (each of the foregoing being an "Indemnitee" and all of
the foregoing being collectively the "Indemnitees") from and against any and all
claims, actions, damages, liabilities, costs and expenses (including, without
limitation, all fees and disbursements of counsel and environmental consultants
which may be incurred in the investigation or defense of any matter) imposed
upon, incurred by or asserted against any Indemnitee by any third party, whether
direct, indirect or consequential and whether based on any federal, state or
foreign laws or other statutes or regulations (including, without limitation,
securities laws, commercial laws and Environmental Laws and regulations), under
common law or on equitable cause, or on contract, tort or otherwise, including,
without limitation, those arising:

                  (a) by reason of, relating to or in connection with the
         execution, delivery, performance or enforcement of any Loan Document,
         any commitments relating thereto, or any transaction contemplated by
         any Loan Document; or

                  (b) in connection with any investigation, litigation,
         proceeding or other action relating to any Loan Document (whether or
         not any Indemnitee is a party thereto); or

                  (c) by reason of, relating to or in connection with any credit
         extended or used under the Loan Documents or any act done or omitted by
         any Person, or any event occurring, in connection therewith, or the
         exercise of any rights or remedies thereunder, including, without
         limitation, any Environmental Activity or Environmental Law; or

                  (d) arising out of, related to or in connection with any
         acquisition or proposed acquisition (including, without limitation, by
         tender offer, merger or other method) by the Borrower or any of its
         Subsidiaries or Affiliates of any Facility (or the assets thereof) or
         any Related Businesses or any Existing Clinic Acquisition, whether or
         not an Indemnitee is a party thereto;


                                       70
<PAGE>   76

provided, however, that, notwithstanding the foregoing, the Borrower shall not
be liable to any Indemnitee for any portion of such claims, damages, liabilities
and expenses resulting from such Indemnitee's or such Indemnitee's Affiliate's,
director's, officer's, employee's, attorney's or agent's gross negligence or
willful misconduct. In the event this indemnity is unenforceable as a matter of
law as to a particular matter or consequence referred to herein, it shall be
enforceable to the full extent permitted by law.

         This indemnification applies, without limitation, to any act, omission,
event or circumstance existing or occurring on or prior to the date of payment
in full of the Advances, including any Environmental Activity or Environmental
Law, regardless of whether the act, omission, event or circumstance constituted
a violation of any Environmental Law at the time of its existence or occurrence.
The indemnification provisions set forth above shall be in addition to any
liability the Borrower may otherwise have. Without prejudice to the survival of
any other obligation of the Borrower hereunder, the indemnities and obligations
of the Borrower contained in this Section 8.06 shall survive the payment in full
of the Advances.

         SECTION 8.07. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Borrower and the Agent and when the
Agent shall have been notified by each Bank that such Bank has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, the
Agent and each Bank and their respective successors and assigns, except that the
Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Banks.

         SECTION 8.08.  Assignments and Participations.

         (a) Each Bank may assign, with the prior consent of the Borrower and
the Agent (which, in either case, shall not be unreasonably withheld), to one or
more banks, financial institutions or other entities all or a portion of its
rights and obligations as a Bank under this Agreement and the other Loan
Documents (including, without limitation, all or a portion of its Commitment,
the Advances owing to it and the Notes held by it in respect of the Committed
Rate Advances); provided, however, that (i) each such assignment shall be of a
constant, and not a varying, percentage of all of the assigning Bank's rights
and obligations under the Loan Documents, (ii) the amount of the Commitments, if
any, of the assigning Bank being assigned pursuant to each such assignment
(determined as of the date of the Assignment and Acceptance with respect to such
assignment) shall in no event be less than $10,000,000, and shall be an integral
multiple of $1,000,000 in excess thereof, or the remaining amount of such Bank's
Commitments, (iii) each such assignment shall be to an Eligible Assignee, and
(iv) the parties to each such assignment shall execute and deliver to the Agent,
for its acceptance and recording in the Register, an Assignment and Acceptance,
together with any Notes subject to such assignment and a processing and
recordation fee of $3,000; provided, further, that each Bank may, without the
consent of the Borrower or the Agent, assign, as collateral or otherwise, any of
its rights under this Agreement and the other Loan Documents (including, without
limitation, the right to payment of principal and interest under the Notes) to
any Federal Reserve Bank, and such assignment of rights to the Federal Reserve
Bank shall not be subject to the conditions and restrictions set forth in items
(i) through (iv) of the immediately foregoing proviso; and provided,


                                       71
<PAGE>   77

further, that each Bank may, without the consent of (but with prior written
notice to) the Borrower or the Agent, assign, in whole or in part, any of its
rights and obligations under this Agreement and the other Loan Documents to any
of its Affiliates, and such assignment to Affiliates shall not be subject to the
conditions and restrictions set forth in items (i) through (iv) of the proviso
above. Upon such execution, delivery, acceptance and recording, from and after
the effective date specified in each Assignment and Acceptance, (x) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations under the Loan Documents have been assigned to it pursuant to such
Assignment and Acceptance, have the rights and obligations of a Bank hereunder
and thereunder and (y) the Bank assignor thereunder shall, to the extent that
rights and obligations under the Loan Documents have been assigned by it
pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Loan Documents (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Bank's rights and obligations under the Loan Documents, such Bank shall cease to
be a party hereto).

         (b) By executing and delivering an Assignment and Acceptance, the Bank
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with any Loan Document or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Loan Document or any other instrument or document furnished
pursuant hereto or thereto; (ii) such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of any Loan Party or the performance or observance by any Loan Party of any of
its obligations under any Loan Document or any other instrument or document
furnished pursuant hereto or thereto; (iii) such assignee confirms that it has
received a copy of each of the Loan Documents, together with copies of the
financial statements referred to in Section 4.01(e) and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, such assigning Bank or any
other Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement or any other Loan Document; (v) such
assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement and the other Loan Documents as are
delegated to the Agent by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of the Loan Documents are required to be performed by it as a Bank.

         (c) The Agent shall maintain at its address referred to in Section 8.02
a copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Banks and the
Commitment and principal amount of the Advances owing to, each Bank from time to
time (the "Register"). The entries in the Register shall be conclusive and
binding for all purposes, absent manifest error, and the Borrower, the


                                       72
<PAGE>   78

Agent and the Banks may treat each Person whose name is recorded in the Register
as a Bank hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Bank at any reasonable time and
from time to time upon reasonable prior notice.

         (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and an assignee representing that it is an Eligible Assignee,
together with any Notes subject to such assignment, the Agent shall, if such
Assignment and Acceptance has been completed and is in substantially the form of
Exhibit E, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to the Borrower. Within five Business Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the Agent
in exchange for the surrendered Committed Rate Notes, new Committed Rate Notes
to the order of such Eligible Assignee in an aggregate principal amount equal to
the principal amount of Committed Rate Advances owed to it pursuant to such
Assignment and Acceptance and, if the assigning Bank has retained any principal
amount of Committed Rate Advances hereunder, new Committed Rate Notes to the
order of the assigning Bank in an aggregate principal amount equal to such
principal amount. Such new Committed Rate Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Committed Rate Notes, shall be dated the effective date of such Assignment and
Acceptance, shall consist of Committed Rate Notes payable to the order of such
Eligible Assignee and, if the assigning Bank has retained ownership of any
Committed Rate Advances hereunder, the assigning Bank in the appropriate
principal amounts, and shall otherwise be in substantially the forms required by
this Agreement.

         (e) Each Bank may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under the Loan
Documents (including, without limitation, all or a portion of its Commitments,
the Notes held by it and reimbursement obligations of the Borrower in respect of
Letters of Credit); provided, however, that (i) such Bank's obligations under
the Loan Documents (including, without limitation, its Commitments to the
Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Bank shall remain the holder of any such Notes for all purposes of
the Loan Documents, and (iv) the Borrower, the Agent and the other Banks shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under the Loan Documents; provided, further, that,
to the extent of any such participation (unless otherwise stated therein and
subject to the preceding proviso), the assignee or purchaser of such
participation shall, to the fullest extent permitted by law, have the same
rights and benefits hereunder as it would have if it were a Bank hereunder; and
provided, further, that each such participation shall be granted pursuant to an
agreement providing that the purchaser thereof shall not have the right to
consent or object to any action by the selling Bank (who shall retain such
right) other than an action which would (i) reduce principal of or interest on
any Advance or fees in which such purchaser has an interest or (ii) postpone any
date fixed for payment of principal of or interest on any such Advance or such
fees.


                                       73
<PAGE>   79

         (f) The Borrower agrees that any Bank purchasing a participation from
another Bank pursuant to Section 2.14 or 8.08(e) may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Bank were the
direct creditor of the Borrower in the amount of such participation.

         (g) Notwithstanding any other provision of this Section 8.08, each
Designated Bidder may assign to one or more Eligible Assignees any Competitive
Bid Note.

         SECTION 8.09. Headings. Article and Section headings in this Agreement
are included for convenience of reference only and shall not constitute a part
of this Agreement for any other purpose.

         SECTION 8.10. Confidentiality. Neither the Agent nor any Bank shall
disclose to any third party any Confidential Information disclosed to the Agent
or such Bank pursuant to the Loan Documents, except that (i) the Agent or any
Bank may disclose Confidential Information to a third party to the extent
compelled by law, subpoena, civil investigative demand, interrogatory or similar
legal process or by any rule, regulation or request of any regulatory authority
having jurisdiction over the Agent or such Bank, as the case may be, (ii) the
Agent or any Bank may disclose Confidential Information to a potential
transferee who is an Eligible Assignee, provided that such potential transferee
agrees to be bound by the same confidentiality obligations as the Banks under
this Section and (iii) the Agent or any Bank may disclose Confidential
Information to its affiliates or its legal counsel or other agents provided that
prior to any such disclosure the Agent or such Bank, as the case may be, informs
such affiliates, counsel or agent of the confidential nature of such
Confidential Information. For purposes hereof, "Confidential Information" is
written information disclosed by the Borrower or any of its Subsidiaries to the
Agent or any Bank pursuant hereto that is not information which (x) has become
generally available to the public, other than as a result of disclosure by the
Agent or such Bank, (y) was available on a non-confidential basis prior to its
disclosure to the Agent or such Bank by the Borrower or any of its Subsidiaries,
or (z) becomes available to the Agent or such Bank on a non-confidential basis
from a source other than the Borrower or any of its Subsidiaries. The Agent and
the Banks acknowledge that the Confidential Information may from time to time
include material non-public information relating to the Borrower or its
Subsidiaries.

         SECTION 8.11. Severability of Provisions. Each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
or unenforceable in any jurisdiction, such provision shall, as to such
jurisdiction, be ineffective only to the extent of such prohibition or
unenforceability without invalidating the remainder of such provision or the
remaining provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

         SECTION 8.12. Independence of Provisions. All agreements and covenants
hereunder and under the Loan Documents shall be given independent effect such
that if a particular action or condition is prohibited by the terms of any such
agreement or covenant, the fact that such 


                                       74
<PAGE>   80

action or condition would be permitted within the limitations of another
agreement or covenant shall not be construed as allowing such action to be taken
or condition to exist.

         SECTION 8.13.  Consent to Jurisdiction.

         (a) The Borrower hereby irrevocably submits to the jurisdiction of any
New York State or Federal court sitting in New York City in any action or
proceeding arising out of or relating to this Agreement or any Loan Document,
and the Borrower hereby irrevocably agrees that all claims in respect of such
action or proceeding may be heard and determined in such New York State or
Federal court. The Borrower hereby irrevocably waives, to the fullest extent it
may effectively do so, the defense of an inconvenient forum to the maintenance
of such action or proceeding. The Borrower hereby irrevocably appoints CT
Corporation System (the "Process Agent"), with an office on the date hereof at
1633 Broadway, New York, New York 10019, United States, as its agent to receive
on behalf of the Borrower and its property service of copies of the summons and
complaint and any other process which may be served in any such action or
proceeding. Such service may be made by mailing or delivering a copy of such
process to the Borrower in care of the Process Agent at the Process Agent's
above address, and the Borrower hereby irrevocably authorizes and directs the
Process Agent to accept such service on his behalf. As an alternative method of
service, the Borrower also irrevocably consents to the service of any and all
process in any such action or proceeding by the mailing of copies of such
process to the Borrower at its address specified in Section 8.02. The Borrower
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.

         (b) Nothing in this section shall affect the right of any Bank or the
Agent to serve legal process in any other manner permitted by law or affect the
right of any Bank or the Agent to bring any action or proceeding against the
Borrower or its property in the courts of any other jurisdictions.

         SECTION 8.14. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION
OF ANY OTHER LAW.

         SECTION 8.15. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENT,
THE ISSUING BANK AND THE BANKS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT' OF OR RELATING TO
ANY OF THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY.

         SECTION 8.16. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                                   ARTICLE II

                       AMOUNTS AND TERMS OF THE ADVANCES

     SECTION 2.01.  The Committed Rate Advances.

     (a) Each Bank severally agrees, on the terms and conditions hereinafter
set forth, to make Committed Rate Advances to the Borrower from time to time on
any Business Day during the period from the Closing Date until the Revolver
Termination Date, in an amount for each such Advance not to exceed such Bank's
Unused Commitment on such Business Day; provided, however, that such Bank shall
not be obligated to make such Committed Rate Advance if, after giving effect to
such Committed Rate Advance and the other Committed Rate Advances to be made by
the other Banks as part of the same Borrowing, the then outstanding aggregate
principal amount of all Committed Rate Advances plus the then existing Letter
of Credit Liability shall exceed the aggregate Commitments of the Banks less
the then outstanding aggregate principal amount of all Competitive Bid
Advances; provided further that, for the purposes of this Section 2.01(a), such
Bank's Unused Commitment shall be deemed to be reduced on such Business Day by
an amount equal to the product of (i) the then outstanding principal amount of
all Competitive Bid Advances and (ii) such Bank's Commitment Percentage (the
"Competitive Bid Reduction").  Each Committed Rate Borrowing shall be in an
aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess
thereof, and shall consist of Advances made on the same day by the Banks
ratably according to their respective Commitments.  Within the limits of each
Bank's Unused Commitment (as deemed reduced by the Competitive Bid Reduction)
in effect from time to time, the Borrower may borrow under this Section
2.01(a), prepay pursuant to Section 2.09 and reborrow under this Section
2.01(a).

     (b) Each Committed Rate Borrowing shall be made on notice, given not later
than 11:00 A.M. (New York City time) (i) on the second Business Day prior to the
date of the proposed Borrowing, in the case of Eurodollar Rate Advances, and
(ii) on the date of the proposed Borrowing, in the case of Base Rate Advances,
by the Borrower to the Agent, which shall give each Bank prompt notice thereof
by telecopier, telex or cable. Each such notice of a Borrowing (a "Notice of
Borrowing") shall be by telecopier, telex or cable, confirmed immediately in
writing, in substantially the form of Exhibit B-1 hereto, specifying therein
(i) the requested date of such Borrowing, (ii) the requested Type of Advances
comprising such Borrowing, (iii) the requested aggregate amount of such
Borrowing, and (iv) in the case of a Borrowing comprised of Eurodollar Rate
Advances, the requested initial Interest Period for each such Advance.  Each
Bank shall, before 12:00 noon (New York City time) on the date of such
Borrowing, make available for the account of its Applicable Lending Office to
the Agent at its address referred to in Section 9.02, in same day funds, such
Bank's ratable portion of such Borrowing.  After the Agent's receipt of such
funds and upon fulfillment of the applicable conditions set forth in Article
IV, the Agent will make such funds available to the Borrower at the Agent's
aforesaid address.  Anything in this subsection (b) above to the contrary
notwithstanding, (A) the Borrower may not select Eurodollar Rate Advances for
any Committed Rate Borrowing if the obligation of the Banks to make Eurodollar
Rate Advances shall then be 

                                     25


<PAGE>   32


suspended pursuant to Section 2.11 and (B) no more than eight Committed Rate 
Borrowings consisting of Eurodollar Rate Advances may be outstanding at any one 
time.

     (c) Each Notice of Borrowing shall be irrevocable and binding on the
Borrower. In the case of any Committed Rate Borrowing which the related Notice
of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the
Borrower shall indemnify each Bank against any loss (including loss of
anticipated profits), cost or expense incurred by such Bank as a result of any
failure to fulfill on or before the date specified in such Notice of Borrowing
for such Borrowing the applicable conditions set forth in Article IV,
including, without limitation, any loss, cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Bank to fund the Advance to be made by such Bank as part of such Borrowing when
such Advance, as a result of such failure, is not made on such date.

     (d) Unless the Agent shall have received notice from a Bank prior to the 
date of any Committed Rate Borrowing that such Bank will not make available to 
the Agent such Bank's ratable portion of such Borrowing, the Agent may assume 
that such Bank has made such portion available to the Agent on the date of such
Borrowing in accordance with subsection (b) above and the Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If and to the extent that such Bank shall not have so    
made such ratable portion available to the Agent, such Bank and the Borrower
severally agree to repay to the Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount
is made available to the Borrower until the date such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the
time to Advances comprising such Borrowing and (ii) in the case of such Bank,
the Federal Funds Rate.  If such Bank shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Bank's
Advance as part of such Borrowing for purposes of this Agreement.  To the
extent that any Bank makes a payment of principal or interest to the Agent
pursuant to this subsection (d), the Borrower shall not be obligated to make
such payment.

     (e) The failure of any Bank to make the Advance to be made by it as part
of any Committed Rate Borrowing shall not relieve any other Bank of its
obligation, if any, hereunder to make its Advance on the date of such
Borrowing, but no Bank shall be responsible for the failure of any other Bank
to make the Advance to be made by such other Bank on the date of any Committed
Rate Borrowing.

     SECTION 2.02.  The Competitive Bid Advances.

     (a) Each Designated Bidder severally agrees, on the terms and conditions
hereinafter set forth, that the Borrower may avail itself of Competitive Bid
Advances from time to time on any Business Day during the period from the
Closing Date until 30 days prior to the Revolver Termination Date, in the
manner set forth in this Section 2.02; provided that the aggregate principal
amount of Competitive Bid Advances made on any Business Day may not exceed the
aggregate Unused Commitments of the Banks on such Business Day less the then
existing Letter of Credit Liability and the then outstanding principal amount
of any other Competitive Bid Advances.                                       


                                     26

     (b) The Borrower may request a Competitive Bid Borrowing by delivering to
the Agent, by telecopier, telex or cable, confirmed immediately in writing, a
request, in substantially the form of Exhibit B-2 (a "Competitive Bid
Request"), specifying therein (i) whether Fixed Rate Advances or LIBOR Advances
are being requested, (ii) the date (which shall be a Business Day) and
aggregate amount of the proposed Competitive Bid Borrowing, (iii) the maturity
date for repayment of the Competitive Bid Advances to be made as part of such
Borrowing (which maturity date shall be a date occurring (A) not less than
seven days after the date of such Borrowing in the case of a request for Fixed
Rate Advances or 30 days after the date of such Borrowing in the case of a
request for LIBOR Advances, but (B) not later than the Revolver Termination
Date), (iv) the interest payment date or dates relating thereto, in the case of
a request for Fixed Rate Advances, and the applicable Interest Period, in the
case of a request for LIBOR Advances, and (v) any other terms to be applicable
to such Borrowing, not later than 11:00 A.M. (New York City time) at least (A)
one Business Day, in the case of a request for Fixed Rate Advances, or (B) four
Business Days, in the case of a request for LIBOR Advances, prior to the date 
of the proposed Competitive Bid Borrowing.  The Agent shall in turn promptly 
notify each Designated Bidder of each request for such Competitive Bid 
Borrowing received by it by sending such Designated Bidder a copy of the 
related Competitive Bid Request.

     (c) Each Designated Bidder may, if, in its sole discretion, it elects to
do so, irrevocably offer to make one or more Competitive Bid Advances to the
Borrower as part of such proposed Competitive Bid Borrowing at a rate or rates
of interest specified by such Designated Bidder in its sole discretion.  Any
such offer (a "Competitive Bid") may be made by notifying the Agent (i) before
10:00 A.M. (New York City time) on the date of such proposed Competitive Bid
Borrowing, in the case of a request for Fixed Rate Advances, and (ii) before
10:00 A.M. (New York City time) on the third Business Day before the date of
such proposed Competitive Bid Borrowing, in the case of a request for LIBOR
Advances (the "Bid Due Date"), specifying the following:

           (A) the amount of each Competitive Bid Borrowing which such
      Designated Bidder would be willing to make as part of such proposed
      Competitive Bid Borrowing (which amount may, subject to the proviso to
      the first sentence of subsection (a) above, exceed a Bank's Commitment
      but may not exceed the principal amount of the Competitive Bid Advances
      of the Type and maturity requested by the Borrower);

           (B) in the case of a request for a LIBOR Advance, the margin above
      or below the applicable Eurodollar Rate (the "LIBOR Margin") offered for
      such Competitive Bid Advance, expressed as a percentage (rounded upwards,
      if necessary, to the nearest 1/16 of one percent) to be added to or
      subtracted from the applicable Eurodollar Rate;

           (C) in the case of a request for a Fixed Rate Advance, the rate of
      interest per annum (rounded upwards, if necessary, to the nearest 1/16 of
      one percent) (the "Fixed Rate") offered for such Competitive Bid Advance;
      and

           (D) the identity of the Designated Bidder submitting the Competitive
      Bid;


                                     27

<PAGE>   34

provided that if the Agent in its capacity as a Designated Bidder shall, in its
sole discretion, elect to make any such Competitive Bid, it shall notify the
Borrower of such Competitive Bid before 9:30 A.M. (New York City time)
on the Bid Due Date.  If any Designated Bidder shall elect not to make such a
Competitive Bid, such Designated Bidder shall so notify the Agent, before 10:00
A.M. (New York City time) on the Bid Due Date, and such Designated Bidder shall
not be obligated to, and shall not, make any Advance as part of such
Competitive Bid Borrowing; provided that the failure by any Designated Bidder
to give such notice shall not cause such Designated Bidder to be obligated to
make any Advance as part of such proposed Competitive Bid Borrowing.  Unless
otherwise agreed by the Borrower and the Agent, no Competitive Bid shall
contain qualifying, conditional or similar language or propose terms other than
or in addition to those set forth in the Competitive Bid Request and, in
particular, no Competitive Bid may be conditioned upon acceptance by the
Borrower of all (or some specified minimum) of the principal amount of the
Competitive Bid Advances offered.

     (d) The Agent shall, as promptly as practicable after the Competitive Bid
is submitted (but in any event not later than 10:15 A.M. (New York City time)
on the Bid Due Date), notify the Borrower of the terms (A) of any Competitive
Bid submitted that is in accordance with subsection (c) above and (B) of any
Competitive Bid that amends, modifies or is otherwise inconsistent with a
previous Competitive Bid with respect to the same Competitive Bid Request.  Any
such subsequent Competitive Bid may be submitted solely to correct a manifest
error in such former Competitive Bid.  The Agent's notice to the Borrower shall
specify (1) the aggregate principal amount of the Competitive Bid Borrowing for
which Competitive Bids have been received and (2) the respective principal
amounts and the Fixed Rates and LIBOR Margins, as the case may be, so offered
by each Designated Bidder (identifying the Designated Bidder that made each
Competitive Bid).

     (e) The Borrower shall, in turn, before 11:00 A.M. (New York City time)
(i) on the day of the proposed Competitive Bid Borrowing, in the case of
requests for Fixed Rate Advances, or (ii) on the third Business Day prior to
the date of the proposed Competitive Bid Advances, in the case of a request for
LIBOR Advances, (or, in any such case, such other time and date as the Borrower
and the Agent, with the consent of the Majority Banks, may agree), either:

           (i)  cancel such Competitive Bid Borrowing by giving the Agent notice
      to that effect, or

           (ii) accept one or more of the Competitive Bids, in its sole
      discretion, by giving notice to the Agent of the amount of each
      Competitive Bid Advance to be made by each Designated Bidder as part of
      such Competitive Bid Borrowing, and reject any remaining Competitive Bids
      by giving the Agent notice to that effect; provided that (A) the Borrower
      may only accept Competitive Bids in the order of the lowest to the
      highest Fixed Rates or LIBOR Margins, as the case may be, offered, (B)
      the Borrower may not accept Competitive Bids in excess of the amount
      requested pursuant to subsection (b) above, or the amount offered
      pursuant to subsection (c) above, for any maturity date or Interest 
      Period, and (C) if two or more Designated Bidders make 


                                     28                                        
<PAGE>   35

     Competitive Bids at the same Fixed Rates or LIBOR Margins, as the  case
     may be, for the same maturity date or Interest Period, the Borrower may
     only accept such Competitive Bids in proportion (as nearly as possible) to
     the amounts which such Designated Bidders offered at such rate for such
     maturity or Interest Period (in amounts of not less than $1,000,000 or an
     integral multiple of $100,000 in excess thereof).

     (f) If the Borrower notifies the Agent that such Competitive Bid Borrowing
is canceled pursuant to subsection (d)(i) above, the Agent shall give prompt
notice thereof to the Designated Bidders, and such Competitive Bid Borrowing
shall not be made.

     (g) If the Borrower accepts one or more of the Competitive Bids made by
any Designated Bidder or Designated Bidders pursuant to subsection (d)(ii)
above, the Agent shall in turn promptly notify (A) each Designated Bidder that
has made a Competitive Bid as described in subsection (c) above, of the date
and aggregate amount of such Competitive Bid Borrowing and whether or not any
Competitive Bid or Bids made by such Designated Bidder pursuant to subsection
(c) above have been accepted by the Borrower, (B) each Designated Bidder that
is to make an Advance as part of such Competitive Bid Borrowing, of the amount
of each Advance to be made by such Bank as part of such Borrowing, and (C) each
Designated Bidder that is to make an Advance as part of such Competitive Bid
Borrowing, as to whether such Competitive Bid Borrowing conforms of the
requirements of Section 2.02.  Each Designated Bidder that is to make an
Advance as part of such Competitive Bid Borrowing shall, before 11:30 A.M. (New
York City time) on the date of such Competitive Bid Borrowing specified in the
notice received from the Agent pursuant to clause (A) of the preceding sentence
(provided such Designated Bidder shall have received a Competitive Bid Note and
a favorable notice from the Agent pursuant to clause (C) of the preceding
sentence), make available to the Agent at its address referred to in Section
9.02, in same day funds, such Designated Bidder's portion of such Competitive
Bid Borrowing.  Upon fulfillment of the applicable conditions set forth in
Article IV and after receipt by the Agent of such funds, the Agent will make
such funds available to the Borrower at the Agent's aforesaid address.
Promptly after each Competitive Bid Borrowing, the Agent shall notify each Bank
of the amount of the Competitive Bid Borrowing, the consequent Competitive Bid
Reduction and the dates upon which such Competitive Bid Reduction commenced and
will terminate.

     (h) Each Competitive Bid Borrowing shall be in an aggregate amount not less
than $3,000,000 or an integral multiple of $1,000,000 in excess thereof and,
following the making of such Competitive Bid Borrowing, the Borrower shall be in
compliance with the limitations set forth in the proviso to the first sentence
of subsection (a) above.

     (i) Each acceptance by Borrower pursuant to subsection (g) above shall be
irrevocable and binding on the Borrower.  In the case of any acceptance of a
Competitive Bid for LIBOR Advances, the Borrower shall indemnify each
Designated Bidder against any loss (including loss of anticipated profits),
cost or expense incurred by such Designated Bidder as a result of any failure
to fulfill on or before the date specified pursuant to subsection (g) above for
such Competitive Bid Borrowing the applicable conditions set forth in Article
IV, including, without limitation, any loss, cost or expense incurred by reason
of the liquidation or 


                                     29
<PAGE>   36


reemployment of deposits or other funds acquired by such Designated Bidder to 
fund the LIBOR Advance to be made by such Bank as part of such Borrowing when 
such Advance, as a result of such failure, is not made on such date.

     (j) The failure of any Designated Bidder to make the Advance to be made by
it as part of any Competitive Bid Borrowing shall not relieve any other
Designated Bidder of its obligation, if any, hereunder to make its Advance on
the date of such Borrowing, but no Designated Bidder shall be responsible for
the failure of any other Designated Bidder to make the Advance to be made by
such other Designated Bidder on the date of any Competitive Bid Borrowing.

     (k) Within the limits and on the conditions set forth in this Section
2.02, the Borrower may from time to time borrow under this Section 2.02, repay
pursuant to Section 2.05 and reborrow under this Section 2.02; provided that
not more than ten Competitive Bid Borrowings may be outstanding at any time
(for which purpose Competitive Bid Advances made on the same date, but having
different maturities or representing Borrowings under different Commitments,
shall be deemed to be separate Competitive Bid Borrowings).

     SECTION 2.03.  Fees.

     (a) Facility Fees.  The Borrower agrees to pay to the Agent, for the
account of each of the Banks, a facility fee on the average daily Commitment of
such Bank from the Closing Date until the Revolver Termination Date at the
Applicable Facility Fee Rate from time to time in effect, payable quarterly in
arrears on the last day of each March, June, September and December, commencing
September 30, 1997, and on the Revolver Termination Date.

     (b) Agency, Auction and Arrangement Fees.  The Borrower agrees to pay to
the Agent, for its own account, the agency fees and the auction fees and to an
Affiliate of the Agent, the arrangement fee, in such amounts and on such dates
as are specified in the letter agreement dated as of June 2, 1997, between the
Borrower and the Agent.

     SECTION 2.04.  Optional Reduction of the Commitments.  The Borrower shall
have the right, upon at least three Business Days' notice to the Agent,
permanently to terminate in whole or reduce ratably in part the Unused
Commitments; provided that (a) each partial reduction shall be in the aggregate
amount of $3,000,000 or an integral $1,000,000 multiple in excess thereof, (b)
each reduction shall be made ratably among the Banks in accordance with their
Unused Commitments, (c) no reduction may reduce the aggregate Commitments of
the Banks below the aggregate amount of the then outstanding Letter of Credit
Liability and the then outstanding principal amount of the Competitive Bid
Advances, and (d) no reduction may reduce the aggregate Commitments of the
Banks while any commitments to lend are in effect under the $150,000,000 Credit
Agreement.

<PAGE>   37

     SECTION 2.05.  Repayment.

     (a) The Borrower shall repay on the Revolver Termination Date the
aggregate principal amount of the Committed Rate Advances of each Bank
outstanding on the Revolver Termination Date, together with accrued interest
thereon.

     (b) The Borrower shall repay the aggregate principal amount of the
Competitive Bid Advances of each Designated Bidder, together with accrued
interest thereon, in such amounts and on such dates as specified pursuant to
Section 2.02(b).

     SECTION 2.06.  Interest.

     (a) The Borrower shall pay interest on the unpaid principal amount of each
Committed Rate Advance made by each Bank from the date of such Advance until
such principal amount shall be paid in full, at the following rates per annum:

         (i) Base Rate Advances.  During such periods as such Advance is a Base
     Rate Advance, a rate per annum equal at all times to the sum of the Base   
     Rate in effect from time to time, payable quarterly in arrears on the last
     day of each March, June, September and December during such periods and on
     the date such Base Rate Advance shall be Converted or paid in full.
     Notwithstanding the foregoing, during the continuance of an Event of
     Default, the principal amount of each Base Rate Advance shall bear
     interest, to the fullest extent permitted by law, from the date on which
     such amount is due until such amount is paid in full, payable on demand,
     at a fluctuating rate per annum equal at all times to 2% per annum above
     the Base Rate in effect from time to time.

         (ii) Eurodollar Rate Advances.  During such periods as such Advance
      is a Eurodollar Rate Advance, a rate per annum equal at all times during
      the Interest Period for such Advance to the sum of the Eurodollar Rate
      for such Interest Period plus the Applicable Eurodollar Rate Margin,
      payable on the last day of such Interest Period and, if such Interest
      Period has a duration of six months, on the day that occurs during such
      Interest Period three months from the first day of such Interest Period;
      provided, however, that in the event that the Applicable Eurodollar Rate
      Margin for any fiscal quarter of the Borrower has not yet been determined
      in accordance with the provisions of the definition of Applicable
      Eurodollar Rate Margin in Section 1.01 as of the time when interest on a
      Eurodollar Rate Advance becomes due, the Borrower shall pay such interest
      on the date when due based on the then existing Applicable Eurodollar
      Rate Margin and any necessary subsequent adjustments in the amount of
      interest payable hereunder (due to any subsequent change in the
      Applicable Eurodollar Rate Margin) shall be made on the first date on
      which any interest on any Committed Rate Advance is payable after the
      date of determination of the Applicable Eurodollar Rate Margin.
      Notwithstanding the foregoing, during the continuance of an Event of
      Default, the principal amount of each Eurodollar Rate Advance shall bear
      interest, to the fullest extent permitted by law, from the date on which
      such amount is due until such amount is paid in full, payable on demand,
      at a rate per annum equal at all times to 2% per annum above the
      Eurodollar 


                                     31

<PAGE>   38


     Rate plus the Applicable Eurodollar Rate Margin until the end
     of the Interest Period applicable to such Eurodollar Rate Advance, at
     which time the rate per annum shall become 2% per annum above the Base
     Rate, in each case as in effect from time to time.

     (b) The Borrower shall pay interest on the unpaid principal amount of each
Competitive Bid Advance from the date of such Advance until such principal
amount shall be paid in full, at the rate of interest for such Advance specified
by the Designated Bidder making such Advance in its Competitive Bid with respect
thereto delivered pursuant to Section 2.02(c), payable on the interest payment
date or dates specified by the Borrower for such Advance in the related
Competitive Bid Request delivered pursuant to Section 2.02(b) and on the
maturity date of such Competitive Bid Advance.  Notwithstanding the foregoing,
during the continuance of an Event of Default, the principal amount of each
Competitive Bid Advance shall bear interest, to the fullest extent permitted by
law, from the date on which such amount is due until such amount is paid in
full, payable on demand, at a rate equal to 2% per annum above the interest rate
specified by the Designated Bidder that made such Advance in its Competitive Bid
with respect thereto delivered pursuant to Section 2.02(c).

     SECTION 2.07.  Interest Rate Determination and Protection.

     (a) The Agent shall give prompt notice to the Borrower and the Banks of
the applicable interest rate under Section 2.06(a)(i) or (ii).

     (b) If, with respect to any Eurodollar Rate Advance, the Majority Banks
notify the Agent that the Eurodollar Rate for any Interest Period for such
Advance will not adequately reflect the cost to such Majority Banks of making,
funding or maintaining their respective Eurodollar Rate Advance for such
Interest Period, the Agent shall forthwith so notify the Borrower and the
Banks, whereupon:

           (i) each Eurodollar Rate Advance will automatically, on the last day
      of the then existing Interest Period therefor, Convert into a Base Rate
      Advance, and

           (ii) the obligation of the Banks to make, or to Convert Advances
      into, Eurodollar Rate Advances shall be suspended until the Agent shall
      notify the Borrower and the Banks that the circumstances causing such
      suspension no longer exist.

     (c) If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advance in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the Agent
will forthwith so notify the Borrower and the Banks and such Advance will
automatically, on the last day of the then existing Interest Period therefor,
Convert into Base Rate Advances.

     SECTION 2.08.  Voluntary and Automatic Conversion of Committed Rate 
                    Advances.

     (a) The Borrower may on any Business Day, upon notice given to the Agent
not later than 11:00 A.M. (New York City time) on the second Business Day prior
to the date of the proposed Conversion and subject to the provisions of
Sections 2.07 and 2.11, Convert all 


                                     32
<PAGE>   39


Committed Rate Advances of one Type comprising the same Borrowing into Committed
Rate Advances of another Type; provided, however, that any Conversion of any
Eurodollar Rate Advances into Base Rate Advances shall be made on, and only on,
the last day of an Interest Period for such Eurodollar Rate Advances. Each such
notice of Conversion shall, within the restrictions specified above, specify (i)
the date of such Conversion, (ii) the Advances to be Converted, and (iii) if
such Conversion is into Eurodollar Rate Advances, the duration of the Interest
Period for each such Advance.

     (b) On the date on which the unpaid aggregate principal amount of
Eurodollar Rate Advances comprising any Committed Rate Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $3,000,000, the
Eurodollar Rate Advances comprising such Borrowing shall automatically Convert
into Base Rate Advances, and on and after such date the Borrower may not
convert such Base Rate Advances to Eurodollar Rate Advances until such time as
the aggregate principal amount of Base Rate Advances equals or exceeds
$3,000,000.

     SECTION 2.09.  Prepayments.

     (a) Voluntary Prepayments.  The Borrower may, upon at least (i) in the
case of Eurodollar Rate Advances, two Business Days' and (ii) in the case of
Base Rate Advances, the same Business Day's notice to the Agent stating the
proposed date and aggregate principal amount of the prepayment, and if such
notice is given, the Borrower shall, prepay the outstanding principal amounts
of the Advances comprising part of the same Committed Rate Borrowing in whole
or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid and, in the case of Eurodollar Rate
Advances, any amounts payable under Section 9.04(b); provided, however, that
(i) each partial prepayment shall be in an aggregate principal amount not less
than $3,000,000 or any integral multiple of $1,000,000 in excess thereof and
(ii) Advances may not be prepaid if any Committed Rate Advances (as defined in
the $150,000,000 Credit Agreement) are outstanding under the $150,000,000
Credit Agreement.  The Borrower may not prepay any Competitive Bid Advances.

     (b) Asset Sales Mandatory Prepayments.  Subject to Section 2.09(f), upon
the sale, lease or other disposition by the Borrower or any Subsidiary of the
Borrower of assets of the Borrower and its Subsidiaries constituting more than
5% of the Consolidated Total Assets of the Borrower and its Subsidiaries at the
time of sale, lease or other disposition, then (x) the Net Cash Proceeds of
such sale, lease or other disposition shall be delivered as soon as practicable
to the Agent and (y) any deferred cash proceeds of such sale, lease, or other
disposition shall be delivered to the Agent as soon as practicable after their
receipt (at which time the same shall become Net Cash Proceeds).  Any such Net 
Cash Proceeds shall be applied in accordance with Section 2.09(e).

     (c) Subordinated Debt Issuance Mandatory Prepayments.  Subject to Section
2.09(f), upon the issuance, if permitted in writing by the Majority Banks, by
the Borrower or any of its Subsidiaries of any Subordinated Debt, whether or
not convertible into or exchangeable for Securities (other than the
subordinated convertible notes issued by the Borrower or any of its
Subsidiaries as consideration for the acquisition of Facilities (or the assets
thereof), any Existing 


                                     33
<PAGE>   40
 Clinic Acquisitions or the acquisition of Related Businesses), then (x) 75% of
the Net Cash Proceeds of such issuance shall be delivered as soon as practicable
to the Agent and (y) 75% of any deferred cash proceeds of such issuance shall be
delivered to the Agent as soon as practicable after their receipt (at which time
the same shall become Net Cash Proceeds).  Any such Net Cash Proceeds shall be
applied in accordance with Section 2.09(e).

     (d) Securities Issuance Mandatory Prepayment.  Subject to Section 2.09(f),
upon the sale or issuance by the Borrower or any of its Subsidiaries of any
Securities, any securities convertible into or exchangeable for Securities
(other than Subordinated Debt subject to Section 2.09(c)), or any warrants,
rights or options to acquire Securities to any Person other than the Borrower
or any of its Subsidiaries other than such sale or issuance pursuant to the
Borrower's employee stock purchase plans or employee and director stock option
plans or similar plan available to physicians practicing at a Facility or
Related Business and other than the issuance of Securities as consideration
for, or the proceeds of which are within 180 days after receipt used for, or
the issuance of subordinated convertible notes as consideration for, the
acquisition of any Facility (or the assets thereof) or any Existing Clinic
Acquisitions or the acquisition of any Related Businesses to the extent such
acquisition satisfies all the requirements of Section 6.02(f)(i) or (ii), as
the case may be), then (x) 50% of the Net Cash Proceeds of such sale or
issuance shall be delivered as soon as practicable to the Agent and (y) 50% of
any deferred cash proceeds of such sale or issuance shall be delivered to the
Agent as soon as practicable after their receipt (at which time the same shall
become Net Cash Proceeds).  Any such Net Cash Proceeds shall be applied in
accordance with Section 2.09(e).

     (e) Application of Prepayments.  Mandatory prepayments pursuant to Section
2.09(b), (c) or (d) shall be:  first, applied to the payment of any amount
required to be prepaid or pledged under the $150,000,000 Credit Agreement;
second, applied to the ratable payment of outstanding Committed Rate Advances,
together with accrued interest to the date of such payment on the principal
amount repaid and any amounts payable pursuant to Section 9.04(b)
in respect thereof; and third, delivered to the Agent to be held as pledged
collateral to be applied to the ratable payment when due of outstanding
Competitive Bid Advances, together with accrued interest to the date of such
payment on the principal amount repaid, to the aggregate amount of such
principal and interest.

     (f) Effect of Investment Grade Rating.  Notwithstanding Sections 2.09(b),
(c), (d) or (e), no prepayment shall be required by any of such sections if at
the time of the sale, lease or other disposition, issuance or sale referred to
therein any of the then outstanding Debt of the Borrower shall then be rated
Investment Grade.

     SECTION 2.10.  Increased Costs.

     (a) If, due to either (i) the introduction of or any change (other than
any change by way of imposition or increase of reserve requirements, in the
case of Eurodollar Rate Advances or LIBOR Advances, included in the Eurodollar
Rate Reserve Percentage) in or in the interpretation of any law or regulation
or (ii) the compliance with any guideline or request from any central bank or
other governmental authority (whether or not having the force of law), there


                                     34


<PAGE>   41

shall be any increase in the cost to any Bank of agreeing to make or making,
funding or maintaining Eurodollar Rate Advances or LIBOR Advances, then the
Borrower shall from time to time, upon demand by such Bank (with a copy of such
demand to the Agent), pay to the Agent for the account of such Bank additional
amounts sufficient to compensate such Bank for such increased cost. A
certificate as to the amount of such increased cost, submitted to the Borrower
and the Agent by such Bank, shall be conclusive and binding for all purposes,
absent manifest error.

     (b) If any Bank determines that compliance with any law or regulation or
any guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital (or the rate of return on capital) required or expected to be
maintained by such Bank or any corporation controlling such Bank and that the
amount of such capital is increased (or such rate of return is reduced) by or
based upon the existence of such Bank's commitment, or offer or agreement, to
lend hereunder and other commitments, or offers or agreements, of this type,
then, upon notice by such Bank (with a copy of such notice to the Agent), the
Borrower shall immediately pay to the Agent for the account of such Bank, from
time to time as specified by such Bank, additional amounts sufficient to
compensate such Bank or such corporation in the light of such circumstances, to
the extent that such Bank reasonably determines such increase in capital (or
reduction in rate of return) to be allocable to the existence of such Bank's
commitment, or offer or agreement, to lend hereunder. Such notice as to such
amounts submitted and delivered to the Borrower and the Agent by such Bank
shall set forth in summary fashion the basis of such allocation and shall be 
conclusive and binding for all purposes, absent manifest error.

     SECTION 2.11.  Illegality.  Notwithstanding any other provision of this
Agreement, if any Bank shall notify the Agent that the introduction of or any
change in or in the interpretation of any law or regulation makes it unlawful,
or any central bank or other governmental authority asserts that it is
unlawful, for any Bank or its Eurodollar Lending Office to perform its
obligations or agreements hereunder to make Eurodollar Rate Advances or LIBOR
Advances or to fund or maintain Eurodollar Rate Advances or LIBOR Advances
hereunder:  (a) in the case of Eurodollar Rate Advances, (i) the obligation of
the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall
be suspended until the Agent shall notify the Borrower and the Banks that the
circumstances causing such suspension no longer exist and (ii) the Borrower
shall forthwith prepay in full all Eurodollar Rate Advances of all Banks then
outstanding, together with interest accrued thereon and any costs payable
pursuant to Section 9.04(b), unless the Borrower, within five Business Days of
notice from the Agent, Converts all Eurodollar Rate Advances of all Banks then
outstanding into Base Rate Advances in accordance with Section 2.08, and (b) in
the case of LIBOR Advances, such Bank shall no longer be obligated to fund any
LIBOR Advance it has agreed to fund thereafter.
     
     SECTION 2.12.  Payments and Computations.

     (a) The Borrower shall make each payment hereunder and under the Notes not
later than 11:00 A.M. (New York City time) on the day when due free and clear
of any taxes, offset or other charge in United States dollars to the Agent at
its address referred to in Section 9.02 in 


                                       35
<PAGE>   42


same day funds. The Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal or interest or facility fees (i)
ratably (other than amounts payable pursuant to Section 2.10, 2.13 or 9.04) to
the Banks for the account of their respective Applicable Lending Offices, in the
case of Committed Rate Advances, and to the applicable Designated Bidder (for
the account of its Applicable Lending Office), in the case of Competitive Bid
Advances, and like funds relating to the payment of any other amount payable to
any Bank to such Bank for the account of its Applicable Lending Office, in each
case to be applied in accordance with the terms of this Agreement.  Upon its
acceptance of an Assignment and Acceptance and recording of the information
contained therein in the Register pursuant to Section 9.08(d), from and after
the effective date specified in such Assignment and Acceptance, the Agent shall
make all payments hereunder in respect of the interest assigned thereby to the
Bank assignee thereunder, and the parties to such Assignment and Acceptance
shall make all appropriate adjustments in such payments for periods prior to
such effective date directly between themselves.

     (b) The Borrower hereby authorizes each Bank, if and to the extent payment
owed to such Bank is not made when due hereunder or under the Note held by such
Bank, to charge from time to time against any or all of the Borrower's accounts
with such Bank any amount so due.

     (c) All computations of interest (other than interest on Base Rate
Advances) and of fees shall be made on the basis of a year of 360 days, and all
computations of interest on Base Rate Advances shall be made on the basis of a
year of 365 or 366 days (as the case may be), in each case for the actual
number of days (including the first day but excluding the last day) occurring
in the period for which such interest or fees are payable. Each determination
by the Agent of an interest rate or fee hereunder shall be conclusive and
binding for all purposes, absent manifest error.

     (d) Whenever any payment hereunder or under the Notes shall be stated to
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or facility fee, as the case
may be; provided, however, if such extension would cause payment of interest on
or principal of Eurodollar Rate Advances or LIBOR Advances to be made in the
next following calendar month, such payment shall be made on the next preceding
Business Day.

     (e) Unless the Agent shall have received notice from the Borrower prior to
the date on which any payment is due to the Banks hereunder in respect of
Committed Rate Advances that the Borrower will not make such payment in full,
the Agent may assume that the Borrower has made such payment in full to the
Agent on such date and the Agent may, in reliance upon such assumption, cause
to be distributed to each Bank on such due date an amount equal to the amount
then due such Bank. If and to the extent the Borrower shall not have so made
such payment in full to the Agent, each Bank shall repay to the Agent forthwith
on demand such amount distributed to such Bank together with interest thereon,
for each day from the date such amount is distributed to such Bank until the
date such Bank repays such amount to the Agent, at the Federal Funds Rate.



                                     36

     (f) Notwithstanding any provision in this Agreement or any other Loan 
Document to the contrary, all payments received by the Agent under the other 
Loan Documents, the application of which are not provided for in such Loan
Documents, may be then or at any time thereafter be applied in whole or
in part by the Agent for the ratable benefit of the Banks (except in the case
of Competitive Bid Advances), against all or part of the Advances or other
obligations of the Borrower hereunder or under the other Loan Documents, in
such order and manner as the Agent shall elect.

     SECTION 2.13.  Taxes.

     (a) Any and all payments by the Borrower hereunder or under the Notes
shall be made, in accordance with Section 2.12, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding,
in the case of each Bank and the Agent, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction under the laws of which such
Bank or the Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Bank, taxes imposed on its income,
and franchise taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall
be required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Bank or the Agent, (i) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.13) such Bank or the Agent (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

     (b) In addition, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or under the Notes or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Notes (hereinafter referred to as "Other Taxes").

     (c) The Borrower will indemnify each Bank and the Agent for the full
amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
2.13) paid by such Bank or the Agent (as the case may be) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date such Bank or the Agent (as the case may be) makes written demand therefor.

     (d) Within 30 days after the date of any payment of Taxes, the Borrower
will furnish to the Agent, at its address referred to in Section 9.02, the
original or a certified copy of a receipt evidencing payment thereof.


                                     37
<PAGE>   44

     (e) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.13 shall survive the payment in full of principal and interest
hereunder and under the Notes.

     (f) Prior to the date of the first Borrowing under this Agreement in the
case of each Bank party hereto on the date hereof, on the date of the
effectiveness of the Assignment and Acceptance pursuant to which it became a
Bank in the case of each other Bank, and within 30 days following the first day
of each calendar year or if otherwise requested from time to time by the
Borrower or the Agent, each Bank organized under the laws of a jurisdiction
outside the United States shall provide the Agent and the Borrower with two
counterparts of each of the forms prescribed by the Internal Revenue Service
(Form 1001 or 4224, or successor form(s), as the case may be, or another
appropriate form) of the United States certifying as to such Bank's status for
purposes of determining exemption from United States withholding taxes with
respect to all payments to be made to such Bank under any Loan Document.
Unless the Borrower and the Agent have received such forms or other documents
satisfactory to them indicating that payments under any Loan Document are not
subject to United States withholding tax, the Borrower or the Agent (if not
withheld by the Borrower) shall withhold taxes from such payments at the
applicable statutory rate, without any obligation to "gross-up" or make such
Bank or the Agent whole under Section 2.13(a); provided, however, that the
Borrower shall have the obligation to make such Bank or the Agent whole and to
"gross-up" under Section 2.13(a), if the failure to so deliver such forms or
make such statements (other than the forms and statements required to be
delivered on or made prior to the date of the initial Borrowing, on the date of
the Assignment and Acceptance pursuant to which an Eligible Assignee became a
Bank) is the result of the occurrence of an event (including, without
limitation, any change in treaty, law or regulation) which (alone or in
conjunction with other events) renders such forms inapplicable, that would
prevent such Bank or the Agent from making the statements contemplated by such
forms or which removes or reduces an exemption (whether partial or complete)
from withholding tax previously available to such Bank or the Agent. Each Bank
(and the Agent, if applicable) will promptly notify the Borrower of the
occurrence (when known to it) of an event contemplated by the foregoing
proviso.

     SECTION 2.14.  Sharing of Payments. Etc.  If any Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of any Committed Rate Advances made by it
(other than pursuant to Section 2.10, 2.13 or 9.04) in excess of its ratable
share of payments on account of such Committed Rate Advances obtained by all the
Banks, such Bank shall forthwith purchase from the other Banks such
participations in such Committed Rate Advances made by them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Bank, such purchase from
each Bank shall be rescinded and such Bank shall repay to the purchasing Bank
the purchase price to the extent of such recovery together with an amount equal
to such Bank's ratable share (according to the proportion of (i) the amount of
such Bank's required repayment to (ii) the total amount so recovered from the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The Borrower
agrees that any Bank so purchasing a participation from another Bank 


                                     38
<PAGE>   45


pursuant to this Section 2.14 may, to the fullest extent permitted by law, 
exercise all its rights of payment (including the right of set-off) with 
respect to such participation as fully as if such Bank were the direct creditor
of the Borrower in the amount of such participation.

     SECTION 2.15.  Evidence of Debt/Register.

     (a) The Debt of the Borrower resulting from the Committed Rate Advances
and Competitive Bid Advances shall be evidenced by the Committed Rate Notes and
the Competitive Bid Notes, respectively, delivered to the Banks pursuant to
Article IV, and the remaining principal amount thereof shall be recorded by the
Banks, and, prior to any transfer, endorsed on the grids thereto in accordance
with the terms of the Notes. The Agent shall also maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the
Borrower under this Agreement and the amounts of principal and interest payable
and paid to each Bank from time to time under this Agreement.

     (b) The Register maintained by the Agent pursuant to Section 9.08(c) shall
include a control account, and a subsidiary account for each Bank, in which
accounts (taken together) shall be recorded:  (i) the date and amount of each
Borrowing, the Commitment to which such Borrowing relates, the Type of Advance
comprising such Borrowing and the Interest Period applicable thereto (if any)
from time to time, (ii) the terms of each Assignment and Acceptance delivered
to and accepted by it, (iii) the amount of any principal or interest due
and payable or to become due and payable from the Borrower to each Bank, and
(iv) the amount of any sum received by the Agent from the Borrower hereunder
and each Bank's share thereof.

     SECTION 2.16.  Use of Proceeds.  The proceeds of the Advances shall be
used by the Borrower for Capital Investments (to the extent permitted under
this Agreement), including, without limitation, acquisitions of Facilities and
Related Businesses (to the extent permitted under this Agreement), and other
general corporate purposes.

     SECTION 2.17.  Outstanding Advances; Existing Collateral

     (a) Conversion to Advances; Termination of Commitment under Existing
Credit Agreement.  On the Closing Date:  (i) all outstanding Base Rate Advances
(as defined in the Existing Credit Agreement) shall automatically become Base
Rate Advances under the Commitments as if borrowed on the Closing Date and
shall thereafter bear interest as provided herein and payable at such times and
otherwise on such terms as are provided herein for Base Rate Advances under the
Commitments, (ii) there shall be no outstanding Eurodollar Rate Advances,
Competitive Bid Advances, or B Advances (as such terms are defined in the
Existing Credit Agreement) and (iii) the A Commitments (as such term is defined
in the Existing Credit Agreement) shall be permanently terminated in full.

     (b) Adjustment Assignments and Payments Among Banks.  Notwithstanding the
requirements set forth in Section 9.08 or any other provision to the contrary
contained herein, on the Closing Date, through the Agent, the Banks shall enter
into such assignments and make such payments (including any accrued interest or
fees) in immediately available funds among themselves as shall be necessary for
each Bank to have funded its ratable share, in accordance 


                                     39
<PAGE>   46



with its Commitment hereunder, of all Existing Base Rate Advances as if such 
Advances were borrowed on the Closing Date hereunder and to participate, in 
accordance with its Commitment hereunder, in all Letters of Credit outstanding 
on the Closing Date.

     (c) Release of Collateral.  On the Closing Date, all Liens on the
Collateral (as defined in the Existing Credit Agreement) shall be released and
terminated, and from and after the Closing Date, the Agent shall execute and
deliver, at the Borrower's expense, such termination statements and other
documents as the Borrower may reasonably request to evidence the release and
termination of such liens.

                                  ARTICLE III

                         AMOUNT AND TERMS OF LETTERS OF
                       CREDIT AND PARTICIPATIONS THEREIN

     SECTION 3.01.  Letters of Credit.  Each Issuing Bank agrees, on the terms
and conditions hereinafter set forth, to Issue for the account of the Borrower,
one or more Letters of Credit from time to time during the period from the
Closing Date until the date which occurs 30 days before the Revolver
Termination Date in an aggregate undrawn amount not to exceed at any time
$20,000,000, each such Letter of Credit upon its Issuance to expire on or
before the earlier of (x) the date which occurs one year from the date of its
Issuance or (y) the Revolver Termination Date; provided, however, that any
letter of credit issued under the Existing Credit Agreement which continues to
be undrawn in whole or in part on the Closing Date shall be deemed to be a
Letter of Credit Issued hereunder from and after the Closing Date; provided,
further, no Issuing Bank shall be obligated or permitted to Issue any Letter of
Credit if:

           (i) after giving effect to the Issuance of such Letter of Credit,
      the then outstanding aggregate amount of the Letter of Credit Liability
      and all Advances (including any Advances required to be made but not
      funded) shall exceed the aggregate amount of the Commitments of the
      Banks; or

           (ii) the Agent or the Majority Banks shall have notified such
      Issuing Bank and the Borrower, that no further Letters of Credit are to
      be Issued by such Issuing Bank due to failure to meet any of the
      applicable conditions set forth in Article IV, and such notice has not
      expired or been withdrawn by the Majority Banks.

Within the limits of the obligations of each Issuing Bank set forth above, the
Borrower may request an Issuing Bank to Issue one or more Letters of Credit,
reimburse such Issuing Bank for payments made thereunder pursuant to Section
3.03(a), and request any Issuing Bank to Issue one or more additional Letters
of Credit under this Section 3.01.

     SECTION 3.02.  Issuing the Letters of Credit.  Each Letter of Credit shall
be Issued on at least five Business Days' notice from the Borrower to the
Issuing Bank specifying the date, amount, expiry, and beneficiary thereof,
accompanied by such application and agreement for letter of credit and other
documents as the Issuing Bank may specify to the Borrower, each in form and
substance satisfactory to the Issuing Bank.  On the date specified by the
Borrower in 


                                     40
<PAGE>   47


such notice and upon fulfillment of the applicable conditions set forth in 
Section 3.01 and Article IV, the Issuing Bank shall Issue such Letter of Credit 
in the form specified in such notice and such application and agreement for 
letter of credit and shall promptly notify the Agent thereof.

     SECTION 3.03.  Reimbursement Obligations.

     (a) Notwithstanding any provisions to the contrary in any application and
agreement for letter of credit applicable to any Letter of Credit, the Borrower
shall:

           (i) pay to the Issuing Bank an amount equal to, and in reimbursement
      for, each amount which such Issuing Bank pays under any Letter of Credit
      on or before the earlier of (A) the time specified therefor in the
      application and agreement for letter of credit applicable to such Letter
      of Credit or (B) the date which occurs one Business Day after payment of
      such amount by such Issuing Bank under such Letter of Credit; and

           (ii) pay to the Issuing Bank interest on any amount remaining unpaid
      under clause (i) above from the date on which such Issuing Bank pays such
      amount under any Letter of Credit until such amount is reimbursed in full
      to such Issuing Bank pursuant to clause (i) above, payable on demand, at
      a fluctuating rate per annum equal to the sum of the Base Rate in effect
      from time to time, provided that any such amount which is not reimbursed
      to such Issuing Bank within one Business Day after notice thereof by the
      Issuing Bank shall thereafter bear interest, until such amount is
      reimbursed in full to such Issuing Bank pursuant to clause (i) above,
      payable on demand, at the Base Rate in effect from time to time plus
      2-1/2% per annum.

     (b) All amounts to be reimbursed to the Issuing Bank in accordance with
subsection (a) above may, subject to the limitations set forth in Section 2.01
(exclusive of the minimum borrowing limitations), be paid from the proceeds of
Committed Rate Advances.  The Borrower hereby authorizes the Banks to make
pursuant to Section 2.01 Committed Rate Advances which are in the amounts of
the reimbursement obligations of the Borrower set forth in subsection (a)
above, and further authorizes the Agent (i) to give the Banks, pursuant to
Section 2.01(b), a Notice of Borrowing with respect to the Borrowing comprised
of such Advances (which shall be Base Rate Advances) and (ii) to distribute the
proceeds of such Advances to the Issuing Bank to pay such amounts. The Borrower
agrees that all such Advances so made shall be deemed to have been requested by
it, and directs that all proceeds thereof shall be used to pay such
reimbursement obligations under subsection (a) above.

     SECTION 3.04.  Participations Purchased by the Banks.

     (a) On the date of Issuance of each Letter of Credit, the Issuing Bank
shall be deemed irrevocably and unconditionally to have sold and transferred to
each Bank without recourse or warranty, and each Bank shall be deemed to have
irrevocably and unconditionally purchased and received from such Issuing Bank,
an undivided interest and participation, to the extent of such Bank's
Commitment Percentage, in effect from time to time, in such Letter of Credit
and all Letter of Credit Liability relating to such Letter of Credit and all
Loan Documents securing,

guaranteeing, supporting, or otherwise benefiting the payment of such Letter of
Credit Liability.  As to each Letter of Credit Issued or to be Issued by the 
Issuing Bank, the Agent will promptly (after it receives notification from the 
Issuing Bank pursuant to Section 3.02) notify each Bank of such Letter of 
Credit and its date of Issue, amount, expiry, and reference number.

     (b) In the event that any reimbursement obligation under Section 3.03(a)
is not paid when due to the Issuing Bank with respect to any Letter of Credit,
the Issuing Bank shall promptly notify the Agent to that effect, and the Agent
shall promptly notify the Banks of the amount of such reimbursement obligation
and each Bank shall immediately pay to the Issuing Bank, in lawful money of the
United States and in same day funds, an amount equal to such Bank's Commitment
Percentage then in effect of the amount of such unpaid reimbursement obligation
with interest at the Federal Funds Rate for each day after such notification
until such amount is paid to the Agent.

     (c) Promptly after the Issuing Bank receives a payment on account of a
reimbursement obligation with respect to any Letter of Credit, the Issuing Bank
shall promptly pay to the Agent, and the Agent shall promptly pay to each Bank
which funded its participation therein, in lawful money of the United States
and in the kind of funds so received, an amount equal to such Bank's ratable
share thereof.

     (d) Upon the request of any Bank, the Agent shall furnish to such Bank
copies of any Letter of Credit and any application and agreement for letter of
credit and other documents related thereto as may be reasonably requested by
such Bank.

     (e) The obligation of each Bank to make payments under Section 3.04(b)
above shall be unconditional and irrevocable and shall be made under all
circumstances, including, without limitation, any of the circumstances referred
to in Section 3.06(b).

     (f) If any payment received on account of any reimbursement obligation
with respect to a Letter of Credit and distributed to a Bank as a participant
under Section 3.04(c) is thereafter recovered from the Issuing Bank in
connection with any bankruptcy or insolvency proceeding relating to the
Borrower, each Bank which received such distribution shall, upon demand by the
Agent, repay to the Issuing Bank such Bank's ratable share of the amount so
recovered together with an amount equal to such Bank's ratable share (according
to the proportion of (i) the amount of such Bank's required repayment to (ii)
the total amount so recovered) of any interest or other amount paid or payable
by such Issuing Bank in respect of the total amount so recovered.

     SECTION 3.05.  Letter of Credit Fees.

     (a) The Borrower hereby agrees to pay nonrefundable letter of credit fees

assume compliance with all conditions for drawing) from the date of Issuance of
such Letter of Credit until the expiry date of such Letter of Credit, (i) to
each Bank (in accordance with its Commitment Percentage) at a rate equal to (A)
the Applicable Eurodollar Rate Margin in effect on the date of Issuance thereof

<PAGE>   49


(ii) to the Issuing Bank at a rate equal to 1/8 of one percent per annum, for
the number of months or any fraction thereof that such Letter of Credit is
outstanding, payable in advance on the  date of Issuance of each Letter of
Credit and on the last day of each March, June, September and December
thereafter prior to the expiry date of such Letter of Credit for the number of
months or fraction thereof until the earlier of (A) the expiry date of such
Letter of Credit and (B) the date three months after such date.

     (b) The Borrower shall pay to the Issuing Bank, for its own account and on
demand, sums equal to standard fees (other than its letter of credit fee),

connection with the Issuance, amendment, administration, transfer or
cancellation of any or all Letters of Credit or in connection with any payment
by such Issuing Bank thereunder.

     SECTION 3.06.  Indemnification: Nature of the Issuing Bank's Duties.

     (a) The Borrower agrees to indemnify and save harmless the Agent, each
Issuing Bank and each Bank from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees) which the Agent, such Issuing Bank or such Bank may incur or 
be subject to as a consequence, direct or indirect, of (i) the Issuance of any 
Letter of Credit or (ii) any action or proceeding relating to a court order, 
injunction, or other process or decree restraining or seeking to restrain such 
Issuing Bank from paying any amount under any Letter of Credit.

     (b) The obligations of the Borrower hereunder with respect to Letters of
Credit shall be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms hereof under all circumstances, including, without
limitation, any of the following circumstances:

           (i)   any lack of validity or enforceability of any Letter of Credit
      or Loan Document or any agreement or instrument relating thereto;

           (ii)  the existence of any claim, setoff, defense or other right
      which the Borrower may have at any time against the beneficiary, or any
      transferee, of any Letter of Credit, or any Issuing Bank, any Bank, or
      any other Person;

           (iii) any draft, certificate, or other document presented under any
      Letter of Credit proving to be forged, fraudulent, invalid or
      insufficient in any respect or any statement therein being untrue or
      inaccurate in any respect;

           (iv)  any lack of validity, effectiveness, or sufficiency of any
      instrument transferring or assigning or purporting to transfer or assign
      any Letter of Credit or the rights or benefits thereunder or proceeds
      thereof, in whole or in part;

           (v)   any loss or delay in the transmission or otherwise of any
      document required in order to make a drawing under any Letter of Credit
      or of the proceeds thereof;

           (vi)  the release or non-perfection of any collateral;


                                     43

<PAGE>   50

           (vii)  any failure of the beneficiary of a Letter of Credit to
      strictly comply with the conditions required in order to draw upon any
      Letter of Credit;

           (viii) any misapplication by the beneficiary of any Letter of Credit
      of the proceeds of any drawing under such Letter of Credit; or

           (ix)   any other circumstance or happening whatsoever, whether or not
      similar to the foregoing;

provided, that, notwithstanding the foregoing, neither an Issuing Bank nor the 
Agent shall be relieved of any liability it may otherwise have as a result of 
its gross negligence or willful misconduct.

     SECTION 3.07.  Increased Costs.

     (a) Change in Law.  If any change in any law or regulation or in the
interpretation thereof by any court or administrative or governmental authority
charged with the administration thereof shall either (i) impose, modify or deem
applicable any reserve, special deposit or similar requirement against letters
of credit issued by an Issuing Bank or (ii) impose on such Issuing Bank or any
Bank any other condition regarding letters of credit or, in the case of such
Bank, its participation hereunder in Letters of Credit, and the result of any
event referred to in the preceding clause (i) or (ii) shall be to increase the
cost to such Issuing Bank of Issuing or maintaining or, in the case of such
Bank, having a participation in Letters of Credit, then, upon demand by such
Issuing Bank or such Bank (with a copy to the Agent), the Borrower shall
immediately pay to such Issuing Bank or such Bank from time to time as
specified by such or such Bank (with a copy to the Agent) additional amounts
which shall be to compensate such Issuing Bank or such Bank for such increased
cost.  Each certificate as to such increased cost, and amount thereof, incurred
by any Issuing Bank or any Bank as a result of any event mentioned in clause
(i) or (ii) above, submitted by such Issuing Bank or such Bank to the Borrower
and the Agent, shall set out in reasonable detail the calculation of such
amounts and shall be conclusive and binding for all purposes, absent manifest
error.

     (b) Capital.  If any Issuing Bank or any Bank determines that compliance
with any law or regulation or with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law)
has or would have the effect of reducing the rate of return on the capital of
any Issuing Bank or such Bank or any corporation controlling such Issuing Bank
or such Bank as a consequence of, or with reference to, such Issuing Bank's
commitment to issue, issuance of, or, with respect to such Bank's commitment,
to participate in, any Letter of Credit hereunder below the rate that such
Issuing Bank, such Bank or such other corporation could have achieved but for
compliance (taking into account the policies of such Issuing Bank, such Bank or
corporation with capital), then the Borrower, shall from time to time, upon
demand by such Issuing Bank or such Bank (with a copy of such demand to the
Agent), immediately pay to such Issuing Bank or such Bank additional amounts
sufficient to compensate such Issuing Bank or other corporation for such
reduction.  A certificate as to such amounts, to the Borrower and the Agent by
such Issuing Bank or such Bank, shall be conclusive and binding 


                                     44

<PAGE>   51

for all purposes, absent manifest error.  Each Issuing Bank and each Bank agree
promptly to notify the Borrower and the Agent of any circumstances that would
Borrower to pay additional amounts pursuant to this subsection (b), provided 
that the failure to give such notice shall not affect the Borrower's 
obligation to pay such additional amounts hereunder.

     (c) Survival of Obligations.  Without prejudice to the survival of any
other obligation of the Borrower hereunder, the agreements and obligations of
the Borrower contained in this Section 3.07 shall survive the payment in full
of the Advances (after the Revolver Termination Date).

     SECTION 3.08.  Uniform Customs and Practice.  The Uniform Customs and
Practice for Documentary Credits as most recently published by the
International Chamber of Commerce ("UCP") shall in all respects be deemed a
part of this Article III as if incorporated herein and shall apply to the
Letters of Credit.

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

     SECTION 5.01.  Representations and Warranties of the Borrower.  The
Borrower represents and warrants as follows:

           (a) The Borrower is a corporation duly incorporated, validly
      existing and in good standing under the laws of its jurisdiction of
      incorporation, is duly qualified as a foreign corporation and is in good
      standing in each jurisdiction as to which the location of its assets or

      hold under lease, its assets, and to execute and deliver, and to perform
      all of its obligations under, each of the Loan Documents to which it is
      or will be a party.  Each of the Borrower's Subsidiaries other than
      Immaterial Subsidiaries is a corporation, limited liability company or
      partnership 


                                     47

      duly organized, validly existing and in good standing under
      the laws of its respective jurisdiction of organization, is duly
      qualified as a foreign corporation, limited liability company or
      partnership and is in good standing in each jurisdiction as to which the
      location of its assets or the nature of its business makes qualification
      necessary, and has all power (corporate, limited liability company,
      partnership or otherwise) to conduct its business and to own, or hold
      under lease, its assets, and to execute and deliver, and to perform all
      of its obligations under, each of the Loan Documents to which it is or
      will be a party.

           (b) The execution, delivery and performance by each Loan Party of
      each Loan Document to which it is or will be a party are within such Loan
      Party's corporate, limited liability company or partnership powers, have
      been duly authorized by all necessary corporate, limited liability
      company or partnership action, and do not contravene (i) such Loan
      Party's certificate or articles of incorporation, by-laws or other
      constituent instruments, or (ii) any law, rule, regulation (including,
      without limitation, Regulation G, T, U or X of the Board of Governors of
      the Federal Reserve System), order, writ, judgment, injunction, decree,
      determination or award binding on or affecting such Loan Party or any of
      its properties, or (iii) any contractual restriction binding on or
      affecting such Loan Party or any of its properties, and do not result in
      or require the creation of any Lien upon or with respect to any of its
      properties; and no Loan Party is in default in any material respect under
      any such law, rule, regulation, order, writ, judgment, injunction,
      decree, determination, award or restriction.

           (c) No authorization or approval or other action by, and no notice
      to or filing with, any governmental authority or regulatory body is
      required for the due execution, delivery and performance by any Loan
      Party of any Loan Document to which it is or will be a party except for
      those which have been duly obtained or made and are in full force and
      effect.

           (d) This Agreement is, and each other Loan Document to which each
      Loan Party will be a party when executed and delivered hereunder will be,
      the legal, valid and binding obligation of such Loan Party enforceable
      against such Loan Party in accordance with its terms.

           (e) The Consolidated balance sheets of the Borrower and its
      Subsidiaries as at December 31, 1996 and March 31, 1997 and the related
      Consolidated statements of operations, stockholders' equity and cash flow
      of the Borrower and its Subsidiaries for the fiscal year and three
      months, respectively, then ended have been furnished to the Agent.  Such
      financial statements, and all financial statements hereafter delivered
      pursuant to Sections 6.04(b) and (c), fairly present, or will fairly
      present, the financial condition of the Borrower and its Subsidiaries as
      at the dates thereof and the results of the operations of the Borrower
      and its Subsidiaries for the periods then ended or ending, all in
      accordance with generally accepted accounting principles consistently
      applied.  Since December 31, 1996, there has been no material adverse
      change, in the business, prospects 


                                     48


<PAGE>   55

      or condition (financial or otherwise) or in the results of operations of 
      the Borrower and its Subsidiaries taken as a whole.

           (f) Each Loan Party has good title to all of its material property,
      free and clear of all Liens, except for Permitted Liens.  Each Lease or
      other agreement relating to the Real Property described in Schedule I
      operated by each Loan Party is a valid and subsisting Lease or other
      agreement and is in full force and effect in accordance with the terms
      thereof; and the Borrower or its Subsidiary is in possession of all such
      leaseholds and no material default by the Borrower or any of its
      Subsidiaries exists under any such Lease or other agreement and, to the
      best of the Borrower's knowledge, no lessor has any accrued right to
      terminate any such Lease or other agreement on account of a default by
      the Borrower or its Subsidiaries.

           (g) Each Service Agreement is a valid and subsisting agreement and
      is in full force and effect in accordance with the terms thereof; and no
      material default by the Borrower or any of its Subsidiaries exists under
      any Service Agreement and, to the best of the Borrower's knowledge, no
      party to any of the Service Agreements has any accrued right to terminate
      any Service Agreement on account of a default by the Borrower or any of
      its Subsidiaries.

           (h) Other than as set forth on Schedule VI, no judgment, order,
      decree, injunction or other restraint affecting any Loan Party has been
      rendered or imposed by any court, governmental agency or arbitrator, and
      there is no pending or, to the best knowledge of the Borrower, threatened
      action or proceeding affecting any Loan Party before any court,
      governmental agency or arbitrator, which could reasonably be expected to
      have a material adverse effect on the business, prospects or condition
      (financial or otherwise) or operations of the Borrower and its
      Subsidiaries, taken as a whole, or which purports to affect the legality,

      of any material term or provision of any Loan Document; or

           (j) any one or more Service Agreements shall be terminated during
      any period of four consecutive fiscal quarters that represent, in the
      aggregate, 5% of the Consolidated EBITDA of the Borrower and its
      Subsidiaries for such period, measured as of the end of any fiscal
      quarter ending after the date of any such termination, provided that it
      shall not be an Event of Default hereunder if the Service Agreement for
      the Facility owned by PhyCor of Ruston, Inc. is terminated without cause;
      or

           (k) any ERISA Event with respect to a Plan shall have occurred and,
      30 days after notice thereof shall have been given to the Borrower by the
      Agent, (i) such ERISA Event shall still exist and (ii) the sum
      (determined as of the date of occurrence of such 


                                     70

      ERISA Event) of the Insufficiency of such Plan and the Insufficiency of
      any and all other Plans with respect to which an ERISA Event shall have
      occurred and then exist (or in the case of a Plan with respect to which an
      ERISA Event described in clauses (iii) through (vi) of the definition of
      ERISA Event shall have occurred and then exist, the liability related
      thereto) is equal to or greater than $5,000,000 for any fiscal year; or

           (l) the Borrower or any ERISA Affiliate shall have been notified by
      the sponsor of a Multiemployer Plan that it has incurred Withdrawal
      Liability to such Multiemployer Plan in an amount that, when aggregated
      with all other amounts required to be paid to Multiemployer Plans by the
      Borrower and its ERISA Affiliates as Withdrawal Liability (determined as
      of the date of such notification), exceeds $5,000,000 for any fiscal
      year; or

           (m) the Borrower or any ERISA Affiliate shall have been notified by
      the sponsor of a Multiemployer Plan that such Multiemployer Plan is in
      reorganization or is being terminated, within the meaning of Title IV of
      ERISA, if as a result of such reorganization or termination the aggregate
      annual contributions of the Borrower and its ERISA Affiliates to all
      Multiemployer Plans that are then in reorganization or being terminated
      have been or will be increased over the amounts contributed to such
      Multiemployer Plans for the respective plan year of each such
      Multiemployer Plan immediately preceding the plan year in which the
      reorganization or termination occurs by an amount exceeding $5,000,000;
      or

           (n) there shall occur any Change of Control; or

           (o) any three of Messrs. Joseph C. Hutts, Thompson S. Dent, Derril
      W. Reeves or Richard D. Wright shall, within any six-month period, cease
      to be employed full time as officers of the Borrower other than by reason
      of the death or incapacity of any such person; or

           (p) since December 31, 1996 there has been, in the reasonable
      judgment of the Agent or the Majority Banks, any material adverse change
      in the Consolidated condition, financial or otherwise, operations,
      properties or prospects of the Borrower and its Subsidiaries taken as a
      whole;

then, and in any such event, the Agent (i) shall at the request, or may with
the consent, of the Majority Banks, by notice to the Borrower, declare the
obligation of each Bank to make Advances and the obligations of the Issuing
Bank to Issue Letters of Credit to be terminated, whereupon the same shall
forthwith terminate, (ii) shall at the request, or may with the consent, of the
Majority Banks, by notice to the Borrower, declare the Notes, all interest
thereon and all other amounts payable under this Agreement to be forthwith due
and payable, whereupon the Notes, all such interest and all such amounts shall
become and be forthwith due and payable, without presentment, demand, protest
or further notice of any kind, all of which are hereby expressly waived by the
Borrower, (iii) shall at the request, or may with the consent, of the Majority
Banks demand that the Borrower, and if such demand is made the Borrower shall,
pay 


                                     71

<PAGE>   78


to the Agent for the benefit of the Issuing Banks, an amount in immediately
available funds equal to the then outstanding Letter of Credit Liability which
shall be held by the Agent (or the Issuing Banks) as cash collateral in a cash
collateral account under the exclusive control and dominion of the Agent (or
Issuing Banks) and applied to the reduction of such Letter of Credit Liability
as drawings are made on outstanding Letters of Credit and (iv) shall at the
request, or may with the consent, of the Majority Banks exercise any other
remedies provided hereunder or by law; provided, however, that in the event of
an actual or deemed entry of an order for relief with respect to the Borrower
or any of its Subsidiaries under the Federal Bankruptcy Code, (A) the
obligation of each Bank to make Advances and of the Issuing Banks to Issue
Letters of Credit shall automatically be terminated and (B) the Notes, all such
interest and all such amounts (including the amounts referred to in clause
(iii) above) shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower.

                                  ARTICLE VIII

                                   THE AGENT

     SECTION 8.01.  Authorization and Action.  Each Bank and each Issuing Bank
hereby appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement as are delegated to the
Agent by the terms hereof, together with such powers as are reasonably
incidental thereto. As to any matters not expressly provided for by this
Agreement (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Majority Banks, and such instructions shall be binding upon all Banks and
all holders of Notes; provided, however, that the Agent shall not be required to
take any action which exposes the Agent to personal liability or which is
contrary to any Loan Document or applicable law.  The Agent agrees to give to
each Bank prompt notice of each notice given to it by the Borrower pursuant to
the terms of this Agreement.

     SECTION 8.02.  Agent's Reliance, Etc.  Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in connection with this
Agreement, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent:  (i) may
treat the payee of any Note as the holder thereof, and treat the Bank that
purchased or funded a participation with respect to a Letter of Credit as the
holder or owner of the Debt resulting therefrom, until the Agent receives
written notice of the assignment or transfer thereof signed by such payee and
including the agreement of the assignee or transferee to be bound hereby as it
would have been if it had been an original Bank party hereto, in form
satisfactory to the Agent; (ii) may consult with legal counsel (including
counsel for the Borrower), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (iii) makes no warranty or representation to any Bank
and shall not be responsible to any Bank for any statements, warranties or
representations (whether written or oral) made in or in 


                                     72



<PAGE>   79
connection with any Loan Document; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of any Loan Document on the part of the Borrower or any Subsidiary of
the Borrower or to inspect the property (including the books and records) of the
Borrower or any such Subsidiary; (v) shall not be responsible to any Bank for
the due execution, legality, validity, enforceability, genuineness, sufficiency
or value of any Loan Document or any other instrument or document furnished
pursuant thereto; and (vi) shall incur no liability under or in respect of any
Loan Document by acting upon any notice, consent, certificate or other
instrument or writing (which may be by telecopier, telegram, cable facsimile or
telex) believed by it to be genuine and signed or sent by the proper party or
parties.

     SECTION 8.03.  Citibank and Affiliates.  With respect to its Commitment,
the Advances made by it, the Notes issued to it and the participations in
Letters of Credit purchased by it, Citibank shall have the same rights and
powers under this Agreement as any other Bank and may exercise the same as
though it were not the Agent; and the term "Bank" or "Banks" shall, unless
otherwise expressly indicated, include Citibank in its individual capacity.
Citibank and its Affiliates may accept deposits from, lend money to, act as
trustee under indentures of, and generally engage in any kind of business with,
the Borrower, any of its Subsidiaries and any Person who may do business with
or own securities of the Borrower or any such Subsidiary, all as if Citibank
were not the Agent and without any duty to account therefor to the Banks.

     SECTION 8.04.  Bank Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent, the Issuing Bank or any
other Bank and based on the financial statements referred to in Section 5.01(e)
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement and the other
Loan Documents.  Each Bank also acknowledges that it will, independently and
without reliance upon the Agent, any Issuing Bank or any other Bank and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Loan Documents.

     SECTION 8.05.  Indemnification.  The Banks agree to indemnify the Agent
and each Issuing Bank (in each case, to the extent not reimbursed by the
Borrower), ratably according to the respective principal amounts of the
Committed Rate Advances then held by each of them (or if no Committed Rate
Advances are at the time outstanding ratably according to the respective
amounts of their Commitments), from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent or any Issuing Bank, as the case
may be, in any way relating to or arising out of this Agreement or any other
Loan Document or any Letter of Credit or any action taken or omitted by the
Agent or such Issuing Bank, as the case may be, under this Agreement or any
other Loan Document or any Letter of Credit, provided that no Bank shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's or any Issuing Bank's, as the case may be, gross
negligence or willful misconduct. Without limitation of the foregoing, each
Bank agrees to 


                                     73

<PAGE>   80
reimburse the Agent and each Issuing Bank promptly upon demand for its ratable
share of any out-of-pocket expenses (including counsel fees) incurred by the
Agent or such Issuing Bank, as the case may be, in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement
or any Letter of Credit, to the extent that the Agent or such Issuing Bank, as
the case may be, is not reimbursed for such expenses by the Borrower.

     SECTION 8.06.  Successor Agent/Issuing Bank.  The Agent may resign at any
time by giving written notice thereof to the Banks and the Borrower and the
Agent and/or any Issuing Bank may be removed at any time with or without cause
by the Majority Banks.  Upon any such resignation or removal, in the case of
the Agent, or removal, in the case of any Issuing Bank, the Majority Banks
shall have the right, subject to the approval of the Borrower (which shall not
be unreasonably withheld), to appoint a successor Agent or a successor Issuing
Bank, as the case may be. If no successor Agent or successor Issuing Bank, as
the case may be, shall have been so appointed by the Majority Banks, and shall
have accepted such appointment, within 30 days after the retiring Agent's
giving of notice of resignation or the Majority Banks' removal of the retiring
Agent or the retiring Issuing Bank, then the retiring Agent or the retiring
Issuing Bank, as the case may be, may, on behalf of the Banks, appoint a
successor Agent or a successor Issuing Bank, as the case may be, which shall be
a commercial bank organized under the laws of the United States of America or
of any State thereof and having a combined capital and surplus of at least
$100,000,000.  Upon the acceptance of any appointment as Agent or as an Issuing
Bank hereunder by a successor Agent or a successor Issuing Bank, respectively,
such successor Agent or Issuing Bank shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent
or the retiring Issuing Bank, as the case may be, and the retiring Agent or the
retiring Issuing Bank, as the case may be, shall be discharged from its duties
and obligations under this Agreement and the other Loan Documents. After any
retiring Agent's resignation or removal hereunder as Agent, or any retiring
Issuing Bank's removal hereunder as an Issuing Bank, the provisions of this
Article VIII shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent or an Issuing Bank, as the case may be, under
this Agreement and the other Loan Documents.  Notwithstanding the foregoing, no
Issuing Bank may be removed unless prior to or contemporaneously with such
removal it shall have received an amount, in immediately available funds, equal
to all outstanding Letter of Credit Liability then outstanding and then owing
to such Issuing Bank and shall have been indemnified by the Borrower, the Banks
and such successor Issuing Bank, to the Issuing Bank's satisfaction, against
all such Letter of Credit Liability. The fees referred to in Section 3.05(b)
shall continue to inure to such Issuing Bank's benefit, with respect to each
Letter of Credit Issued by it, until such time as all Letter of Credit
Liability in respect of such Letter of Credit has been discharged in full.

     SECTION 8.07.  Documentation Agent.  The Documentation Agent, as such,
shall have no duties or obligations whatsoever with respect to this Agreement,
the Notes or any of the other Loan Documents.


                                     74

                                   ARTICLE IX

                                 MISCELLANEOUS

     SECTION 9.01.  Amendments, Etc.  No amendment or waiver of any provision
of this Agreement or the Notes or the Loan Documents, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Majority Banks (or consented to in
writing in the case of the Loan Documents), and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given; provided, however, that no amendment, waiver or consent shall,
unless in writing and signed by all the Banks, do any of following:  (a) waive
any of the conditions specified in Article IV, (b) increase the Commitments of
the Banks or subject the Banks to any additional monetary obligations, (c)
reduce the principal of, or interest on, the Committed Rate Advances or the
Committed Rate Notes or any fees or other amounts payable hereunder, (d)

other amounts payable hereunder or waive any such payment when due, (e) change
the percentage of the Commitments or of the aggregate unpaid principal amount
of the Committed Rate Advances or the Committed Rate Notes, or the number or
percentage of Banks, which shall be required for the Banks or any of them to
take any action hereunder or (f) amend this Section 9.01; provided, further,
that no amendment, waiver or consent shall, in writing and signed by the Agent
in addition to the Banks required above to take such action, affect the rights
or duties of the Agent under this Agreement or any Note; and provided, further,
that no amendment, waiver or consent shall, unless in writing and signed by any
Issuing Bank in addition to the Banks required above to take such action,
affect the rights or duties of such Issuing Bank under this Agreement; and
provided also that no amendment, waiver or consent, unless in writing and
signed by the Designated Bidder holding such Note, affect the rights of the
holder of a Competitive Bid Note under such Note.

     SECTION 9.02.  Notices, Etc.  All notices and other communications provided
for hereunder shall be in writing (including telecopier, telegraphic, telex or
cable communication) and mailed (by certified mail, return receipt requested),
telecopied, telegraphed, telexed, cabled or delivered, if to the Borrower, at
its address at 30 Burton Hills Blvd., Suite 400, Nashville, TN 37215, Attention:

<PAGE>   82

pursuant to Article III or VIII shall not be effective until received by the 
Agent or such Issuing Bank, as the case may be.

     SECTION 9.03.  No Waiver: Remedies.  No failure on the part of any Bank,
any Issuing Bank or the Agent to exercise, and no delay in exercising, any
right under any Loan Document shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right.  The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

     SECTION 9.04.  Costs. Expenses and Taxes.

     (a) The Borrower agrees to pay the Agent and each Issuing Bank on demand
all reasonable costs and expenses of the Agent and such Issuing Bank in
connection with the preparation, negotiation, approval, execution, delivery,
filing, recording, administration, modification and amendment of the Loan
Documents and the other documents to be delivered under the Loan Documents,
including, without limitation, the reasonable fees and out-of-pocket expenses of
special and local counsel for the Agent and such Issuing Bank with respect
thereto and with respect to advising the Agent and such Issuing Bank as to its
rights and responsibilities under the Loan Documents and the other documents to
be delivered hereunder and thereunder. The Borrower further agrees to pay on
demand (i) all costs and expenses, if any, of the Agent, each Issuing Bank or
any Bank in connection with the enforcement (whether through negotiations or
legal proceedings, in bankruptcy, reorganization or other insolvency proceedings
or otherwise) of the Loan Documents and the other documents to be delivered
under the Loan Documents, including, without limitation, reasonable counsel fees
and expenses in connection with the enforcement of rights under this Section
9.04(a), and (ii) all costs and expenses in connection with appraisals,
valuations, audits and search reports, all insurance and title costs, and all
filing and recording fees required hereby or associated with any enforcement of
rights or remedies specified in clause (i).

     (b) If any payment of principal of, or Conversion of, any Eurodollar Rate
Advance or LIBOR Advance is made other than on the last day of an Interest
Period relating to such Advance, as a result of a payment (including, without
limitation, any payment pursuant to Section 2.09) or Conversion pursuant to
Section 2.08 or 2.11 or acceleration of the maturity of the Notes pursuant to
Section 7.01 or for any other reason, the Borrower shall, upon demand by any
Bank (with a copy of such demand to the Agent), pay to the Agent for the
account of such Bank any amounts required to compensate such Bank for any
additional losses (including loss of anticipated profits), costs or expenses
which it may reasonably incur as a result of such payment or Conversion,
including, without limitation, any loss, cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by such
Bank to fund or maintain such Advance.

     SECTION 9.05.  Right of Set-off.  Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making of the request or the
granting of the consent specified by Section 7.01 to authorize the Agent to
declare the Notes due and payable pursuant to the provisions of Section 7.01 or
to demand payment of (or cash collateralization of) all then 


                                     76

<PAGE>   83
outstanding Letter of Credit Liability, each Bank is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by such Bank
to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under any Loan Document to
such Bank (including, to the fullest extent permitted by law, obligations
indirectly owed to such Bank by virtue of its purchase of a participation of the
Letter of Credit Liability pursuant to Section 3.04), whether or not such Bank
shall have made any demand under this Agreement or such Note and although such
obligations may be unmatured.  Each Bank agrees promptly to notify the Borrower
after any such set-off and application made by such Bank, provided that the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Bank under this Section 9.05 are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) which such Bank may have.

     SECTION 9.06.  Indemnification.  The Borrower agrees to defend, protect,
indemnify and hold harmless the Agent, each Bank and each Issuing Bank and
their respective Affiliates and the directors, officers, employees, attorneys
and agents of the Agent, each Bank, each Issuing Bank and such Affiliates (each
of the foregoing being an "Indemnitee" and all of the foregoing being
collectively the "Indemnitees") from and against any and all claims, actions,
damages, liabilities, costs and expenses (including, without limitation, all
fees and disbursements of counsel and environmental consultants which may be 
incurred in the investigation or defense of any matter) imposed upon, incurred 
by or asserted against any Indemnitee by any third party, whether direct, 
indirect or consequential and whether based on any federal, state or foreign 
laws or other statutes or regulations (including, without limitation, 
securities laws, commercial laws and Environmental Laws and regulations), 
under common law or on equitable cause, or on contract, tort or otherwise, 
including, without limitation, those arising:

           (a) by reason of, relating to or in connection with the execution,
      delivery, performance or enforcement of any Loan Document, any
      commitments relating thereto, or any transaction contemplated by any Loan
      Document; or

           (b) in connection with any investigation, litigation, proceeding or
      other action relating to any Loan Document (whether or not any Indemnitee
      is a party thereto); or

           (c) by reason of, relating to or in connection with any credit
      extended or used under the Loan Documents or any act done or omitted by
      any Person, or any event occurring, in connection therewith, or the
      exercise of any rights or remedies thereunder, including, without
      limitation, any Environmental Activity or Environmental Law; or

           (d) arising out of, related to or in connection with any acquisition
      or proposed acquisition (including, without limitation, by tender offer,
      merger or other method) by the Borrower or any of its Subsidiaries or
      Affiliates of any Facility (or the assets thereof) or any Related
      Businesses or any Existing Clinic Acquisition, whether or not an
      Indemnitee is a party thereto;


                                     77
<PAGE>   84

provided, however, that, notwithstanding the foregoing, the Borrower shall not
be liable to any Indemnitee for any portion of such claims, damages,
liabilities and expenses resulting from such Indemnitee's or such Indemnitee's
Affiliate's, director's, officer's, employee's, attorney's or agent's gross
negligence or willful misconduct.  In the event this indemnity is unenforceable
as a matter of law as to a particular matter or consequence referred to herein,
it shall be enforceable to the full extent permitted by law.

     This indemnification applies, without limitation, to any act, omission, 
event or circumstance existing or occurring on or prior to the date of payment 
in full of the Advances, including any Environmental Activity or Environmental
Law, regardless of whether the act, omission, event or circumstance constituted
a violation of any Environmental Law at the time of its existence or
occurrence.  The indemnification provisions set forth above shall be in
addition to any liability the Borrower may otherwise have.  Without prejudice
to the survival of any other obligation of the Borrower hereunder, the
indemnities and obligations of the Borrower contained in this Section 9.06
shall survive the payment in full of the Advances.

     SECTION 9.07.  Binding Effect.  This Agreement shall become effective when
it shall have been executed by the Borrower, the Agent and each Issuing Bank
and when the Agent shall have been notified by each Bank that such Bank has
executed it and thereafter shall be binding upon and inure to the benefit of
the Borrower, the Agent, each Issuing Bank and each Bank and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Banks.

     SECTION 9.08.  Assignments and Participations.

     (a) Each Bank may assign, with the prior consent of the Borrower, any
Issuing Bank and the Agent (which, in either case, shall not be unreasonably
withheld), to one or more banks, financial institutions or other entities all
or a portion of its rights and obligations as a Bank under this Agreement and
the other Loan Documents (including, without limitation, all or a portion of
its Commitment, the Advances owing to it and the Notes held by it in respect of
the Committed Rate Advances and its participation in reimbursement obligations
of the Borrower in respect of Letters of Credit); provided, however, that (i)
each such assignment shall be of a constant, and not a varying, percentage of
all of the assigning Bank's rights and obligations under the Loan Documents,
(ii) the amount of the Commitments, if any, of the assigning Bank being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be
less than $10,000,000, and shall be an integral multiple of $1,000,000 in
excess thereof, or the remaining amount of such Bank's Commitments, (iii) each
such assignment shall be to an Eligible Assignee, and (iv) the parties to each
such assignment shall execute and deliver to the Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any
Notes subject to such assignment and a processing and recordation fee of
$3,000; provided, further, that each Bank may, without the consent of the
Borrower or the Agent, assign, as collateral or otherwise, any of its rights
under this Agreement and the other Loan Documents (including, without
limitation, the right to payment of principal and interest under the Notes) to
any Federal Reserve Bank, and such assignment of rights to the Federal
Reserve Bank shall not be subject to the conditions and restrictions set forth
in items (i) through (iv) of the immediately foregoing proviso; and provided,
further, that each Bank may, without the consent of (but with prior written
notice to) the Borrower or the Agent, assign, in whole or in part, any of its
rights and obligations under this Agreement and the other Loan Documents to any
of its Affiliates, and such assignment to Affiliates shall not be subject to
the conditions and

restrictions set forth in items (i) through (iv) of the proviso above.  Upon
such execution, delivery, acceptance and recording, from and after the effective
date specified in each Assignment and Acceptance, (x) the assignee thereunder
shall be a party hereto and, to the extent that rights and obligations under the
Loan Documents have been assigned to it pursuant to such Assignment and
Acceptance, have the rights and obligations of a Bank hereunder and thereunder
and (y) the Bank assignor thereunder shall, to the extent that rights and
obligations under the Loan Documents have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under the Loan Documents (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Bank's rights
and obligations under the Loan Documents, such Bank shall cease to be a party
hereto).

     (b) By executing and delivering an Assignment and Acceptance, the Bank
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows:  (i) other than as provided in
such Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with any Loan Document or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Loan Document or any other instrument or document furnished
pursuant hereto or thereto; (ii) such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of any Loan Party or the performance or observance by any Loan Party of any of
its obligations under any Loan Document or any other instrument or document
furnished pursuant hereto or thereto; (iii) such assignee confirms that it has
received a copy of each of the Loan Documents, together with copies of the
financial statements referred to in Section 5.01(e) and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Agent, any Issuing Bank, such
assigning Bank or any other Bank and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement or any other Loan Document;
(v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the other Loan Documents as are
delegated to the Agent by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of the Loan Documents are required to be performed by it as a Bank.

     (c) The Agent shall maintain at its address referred to in Section 9.02 a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Banks and the
Commitment and principal amount of the Advances owing to, each Bank from time
to time (the "Register").  The entries in the Register 


                                     79

<PAGE>   86

shall be conclusive and binding for all purposes, absent manifest error,        
and the Borrower, the Agent and the Banks may treat each Person whose name is
recorded in the Register as a Bank hereunder for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower or
any Bank at any reasonable time and from time to time upon reasonable prior     
notice.

     (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and an assignee representing that it is an Eligible Assignee,
together with any Notes subject to such assignment, the Agent shall, if such
Assignment and Acceptance has been completed and is in substantially the form
of Exhibit E, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register, and (iii) give prompt notice
thereof to the Borrower.  Within five Business Days after its receipt of such
notice, the Borrower, at its own expense, shall execute and deliver to the
Agent in exchange for the surrendered Committed Rate Notes, new Committed Rate
Notes to the order of such Eligible Assignee in an aggregate principal amount
equal to the principal amount of Committed Rate Advances owed to it pursuant to
such Assignment and Acceptance and, if the assigning Bank has retained any
principal amount of Committed Rate Advances hereunder, new Committed Rate Notes
to the order of the assigning Bank in an aggregate principal amount equal to
such principal amount.  Such new Committed Rate Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Committed Rate Notes, shall be dated the effective date of such Assignment and
Acceptance, shall consist of Committed Rate Notes payable to the order of such
Eligible Assignee and, if the assigning Bank has retained ownership of any
Committed Rate Advances hereunder, the assigning Bank in the appropriate
principal amounts, and shall otherwise be in substantially the forms required
by this Agreement.

     (e) Each Bank may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under the Loan
Documents (including, without limitation, all or a portion of its Commitments,
the Notes held by it and reimbursement obligations of the Borrower in respect
of Letters of Credit); provided, however, that (i) such Bank's obligations
under the Loan Documents (including, without limitation, its Commitments to the
Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely
responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of any such Notes for all
purposes of the Loan Documents, and (iv) the Borrower, the Agent, each Issuing
Bank and the other Banks shall continue to deal solely and directly with such
Bank in connection with such Bank's rights and obligations under the Loan
Documents; provided, further, that, to the extent of any such participation
(unless otherwise stated therein and subject to the preceding proviso), the
assignee or purchaser of such participation shall, to the fullest extent
permitted by law, have the same rights and benefits hereunder as it would have
if it were a Bank hereunder; and provided, further, that each such
participation shall be granted pursuant to an agreement providing that the
purchaser thereof shall not have the right to consent or object to any action
by the selling Bank (who shall retain such right) other than an action which
would (i) reduce principal of or interest on any Advance or fees in which such
purchaser has an interest or (ii) postpone any date fixed for payment of
principal of or interest on any such Advance or such fees.


                                     80
<PAGE>   87


     (f) The Borrower agrees that any Bank purchasing a participation from
another Bank pursuant to Section 2.14 or 9.08(e) may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Bank were the
direct creditor of the Borrower in the amount of such participation.

     (g) Notwithstanding any other provision of this Section 9.08, each
Designated Bidder may assign to one or more Eligible Assignees any Competitive
Bid Note.

     SECTION 9.09.  Headings.  Article and Section headings in this Agreement
are included for convenience of reference only and shall not constitute a part
of this Agreement for any other purpose.

     SECTION 9.10.  Confidentiality.  Neither the Agent nor any Bank shall
disclose to any third party any Confidential Information disclosed to the Agent
or such Bank pursuant to the Loan Documents, except that (i) the Agent or any
Bank may disclose Confidential Information to a third party to the extent
compelled by law, subpoena, civil investigative demand, interrogatory or
similar legal process or by any rule, regulation or request of any regulatory
authority having jurisdiction over the Agent or such Bank, as the case may be,
(ii) the Agent or any Bank may disclose Confidential Information to a potential
transferee who is an Eligible Assignee, provided that such potential transferee
agrees to be bound by the same confidentiality obligations as the Banks under
this Section and (iii) the Agent or any Bank may disclose Confidential
Information to its affiliates or its legal counsel or other agents provided 
that prior to any such disclosure the Agent or such Bank, as the case may be, 
informs such affiliates, counsel or agent of the confidential nature of
such Confidential Information.  For purposes hereof, "Confidential Information"
is written information disclosed by the Borrower or any of its Subsidiaries to
the Agent or any Bank pursuant hereto that is not information which (x) has
become generally available to the public, other than as a result of disclosure
by the Agent or such Bank, (y) was available on a non-confidential basis prior
to its disclosure to the Agent or such Bank by the Borrower or any of its
Subsidiaries, or (z) becomes available to the Agent or such Bank on a
non-confidential basis from a source other than the Borrower or any of its
Subsidiaries.  The Agent and the Banks acknowledge that the Confidential
Information may from time to time include material non-public information
relating to the Borrower or its Subsidiaries.

     SECTION 9.11.  Severability of Provisions.  Each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
or unenforceable in any jurisdiction, such provision shall, as to such
jurisdiction, be ineffective only to the extent of such prohibition or
unenforceability without invalidating the remainder of such provision or the
remaining provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

     SECTION 9.12.  Independence of Provisions.  All agreements and covenants
hereunder and under the Loan Documents shall be given independent effect such
that if a particular action or condition is prohibited by the terms of any such
agreement or covenant, the fact that such 


                                     81

<PAGE>   88

action or condition would be permitted within the limitations of another 
agreement or covenant shall not be construed as allowing such action to be 
taken or condition to exist.

     SECTION 9.13.  Consent to Jurisdiction.

     (a) The Borrower hereby irrevocably submits to the jurisdiction of any New
York State or Federal court sitting in New York City in any action or proceeding
arising out of or relating to this Agreement or any Loan Document, and the
Borrower hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in such New York State or Federal court. 
The Borrower hereby irrevocably waives, to the fullest extent it may
effectively do so, the defense of an inconvenient forum to the maintenance of
such action or proceeding.  The Borrower hereby irrevocably appoints CT
Corporation System (the "Process Agent"), with an office on the date hereof at
1633 Broadway, New York, New York 10019, United States, as its agent to receive
on behalf of the Borrower and its property service of copies of the summons and
complaint and any other process which may be served in any such action or
proceeding.  Such service may be made by mailing or delivering a copy of such
process to the Borrower in care of the Process Agent at the Process Agent's
above address, and the Borrower hereby irrevocably authorizes and directs the
Process Agent to accept such service on his behalf.  As an alternative method
of service, the Borrower also irrevocably consents to the service of any and
all process in any such action or proceeding by the mailing of copies of such
process to the Borrower at its address specified in Section 9.02.  The Borrower
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law.

     (b) Nothing in this section shall affect the right of any Bank, any
Issuing Bank or the Agent to serve legal process in any other manner permitted
by law or affect the right of any Bank, any Issuing Bank or the Agent to bring
any action or proceeding against the Borrower or its property in the courts of
any other jurisdictions.

     SECTION 9.14.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE
APPLICATION OF ANY OTHER LAW.

     SECTION 9.15.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE AGENT, THE
ISSUING BANK AND THE BANKS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT' OF OR RELATING TO ANY OF
THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY.

     SECTION 9.16.  Execution in Counterparts.  This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN


                               I. NAME AND PURPOSE

         PhyCor, Inc. ("PhyCor") has determined that it is reasonable, desirable
and necessary to provide for retirement benefits to certain executive employees
of PhyCor that supplement the retirement benefits provided under the PhyCor,
Inc. Savings and Profit Sharing Plan. Accordingly, PhyCor has established this
PhyCor Supplemental Executive Retirement Plan (the "Plan") in order to enable
PhyCor to attract into and retain persons of outstanding competence. This Plan
is to be an unfunded plan of deferred compensation covering a select group of
management or highly compensated employees, within the meaning of sections
201(2), 301(a)(3), and 401(a)(1) of ERISA, and is intended to be exempt from
Parts 2, 3, and 4 of ERISA.

         This Plan shall be effective January 1, 1997, and shall continue
indefinitely until it is terminated by an amendment permissible under Section .


                                 II. DEFINITIONS

beneficial ownership or control of securities of PhyCor representing 50% or more
of the combined voting power of PhyCor's then outstanding securities; provided,
however, a Change in Control shall not be deemed to have occurred solely as a

         2.5      "Compensation" means the average of a Participant's annual
compensation, as defined under the Qualified Plan, that is paid over the three
consecutive fiscal years that will produce the highest average, adjusted as
follows:

                  (a)      Annual compensation under the Qualified Plan shall be
         calculated without regard to the limits on compensation imposed by
         section 401(a)(17) of the Code.

                  (b)      If termination of employment occurs after a Change in
         Control, Compensation shall be the Compensation on the date the Change
         in Control occurs compounded by the Interest Rate through the
         Commencement Date.

         2.6      "Death Benefit" means (a) in the case of a Participant who
dies prior to the Early Retirement Date, three times the Participant's
Compensation divided by one minus the maximum federal income tax rate in the
year of payment and (b) in any case of a Participant who dies after the Early
Retirement Date, one times the Participant's Compensation divided by one minus
the maximum federal income tax rate in the year of payment.

         2.7      "Disability" shall have the same meaning as under PhyCor's
long term disability plan.

         2.8      "Early Retirement Date" means, unless there is a Change in
Control, the date a Participant, other than Joe Hutts, attains 55 years of age

Control or date the Participant attains 60 years of age.

         2.13     "Normal Retirement Benefit" means the benefit described in
Section.

         2.14     "Participant" means an individual who is: (i) a member of a

compensated employees.

contributions made by PhyCor to the Qualified Plan on behalf of a Participant
over the three completed calendar years immediately preceding the date a

at the Interest Rate.

         2.16     "Qualified Benefit" means an amount equal to the maximum
annual payment which would be provided by an annuity that could be purchased

year term certain.

at a rate of interest equal to the Interest Rate. Where termination occurs after
a Change in Control, the Qualified Plan Balance shall be the amount of such
balance on the date of the Change in Control compounded at the Interest Rate
through the Commencement Date. For purposes of calculating the Normal Retirement
Benefit under Sections and , the Qualified Benefit shall be calculated on
January 1 following the date the Participant attains 60 years of age but the
Participant's Qualified Plan balance for purposes of such calculation shall be
deemed to be the amount of such balance upon the date employment terminated
compounded at the Interest Rate.

         2.19     "Trust" means the grantor trust which is described in Section
and has been established to hold, administer, and invest the assets accrued and
reserved to pay benefits under the Plan and for the purposes otherwise stated in

Participant upon designation as such by the Committee.


                                        3

<PAGE>   4



         3.2      Effective Date of Participation. An Executive employee shall
become a Participant in this Plan as of the date designated by the Committee.
All deferred compensation amounts that are accrued under this Plan shall be
deemed to have been accrued as of the last day of the fiscal year of the Plan
which includes the last day of PhyCor's fiscal year for which the accrual is
calculated.


                               IV. ADMINISTRATION

         4.1      Administration Committee. This Plan shall be administered by
the Committee. The Committee shall have full discretionary power and authority
to interpret, construe and administer this Plan and the Committee's
interpretations and constructions thereof, and actions thereunder, including the
amount or recipient of the payment to be made from this Plan including
determination of the Qualified Benefit, shall be binding and conclusive on all
persons for all purposes.

         4.2      Funding. All benefits payable hereunder shall be unfunded for
purposes of section 83 of the Code and Title I of ERISA.

                  (a)      PhyCor shall establish the Trust as a reserve for the
         benefits payable hereunder and for the purposes stated in the Trust
         instrument. PhyCor shall be the grantor of the Trust and the Trust
         shall be established for the benefit of the Participants herein and, in
         the case of the insolvency or bankruptcy of PhyCor, for the benefit of
         the general creditors of PhyCor. To the extent that the Participants'
         benefits are not paid from the Trust, such benefits shall be paid from
         the general assets of PhyCor. Except as provided in the Trust, the
         Participants shall have no funded, secured, or preferential right to
         payment hereunder, but rather shall at all times have the status of a
         general unsecured creditor.

                  (b)      The Committee, in its sole discretion, may at any
         time prior the time that a Change in Control is being considered by the
         officers, shareholders or directors of PhyCor, cease funding the Trust.

         4.3      Claims Procedure. Prior to or upon becoming entitled to
receive a benefit hereunder, a Participant or his beneficiary ("Claimant") shall
request payment of such benefits at the time and in the manner prescribed by the
Committee. The Committee may direct payment of benefits without requiring the
filing of a claim therefor, if the Committee has knowledge of such Claimant's
whereabouts. The Committee shall provide adequate notice in writing as
prescribed pursuant to paragraph (b) below to any Claimant whose claim for
benefits under the Plan has been denied.

                  (a)      Such notice must be sent within 90 days of the date
         the claim is received by the Committee unless special circumstances
         require an extension of time for processing the claim. Such extension
         shall not exceed 90 days and no extension shall be

                                        4

<PAGE>   5



         allowed unless, within the initial 90 day period, the claimant is sent
         an extension notice indicating the special circumstances requiring the
         extension and specifying a date by which the Committee expects to
         render its decision.

                  (b)      The Committee's notice of denial to the Claimant
         shall set forth the following:

                           (1) the specific reason or reasons for the denial;

                           (2) specific references to pertinent Plan provisions
                  on which the Committee based its denial;

                           (3) a description of any additional material and
                  information needed for the Claimant to perfect his or her
                  claim and an explanation of why the material or information is
                  needed;

                           (4) a statement that the Claimant may request a
                  review upon written application to the Committee, review
                  pertinent Plan documents, and submit issues and comments in
                  writing;

                           (5) a statement that any appeal of the Committee's
                  adverse determination must be made in writing to the Committee
                  within 60 days after receipt of the Committee's notice of
                  denial of benefits, and that failure to appeal the action to
                  the Committee in writing within the 60-day period will render
                  the Committee's determination final, binding, and conclusive;
                  and

                           (6) the address of the Committee to which the
                  Claimant may forward his or her appeal.

                  (c)      If the Claimant should appeal to the Committee, the
         Claimant or a duly authorized representative, may submit, in writing,
         whatever issues and comments the Claimant deems pertinent. The
         Committee shall re-examine all facts related to the appeal and make a
         final determination as to whether the denial of benefits is justified
         under the circumstances. The Committee shall advise the Claimant in
         writing of its decision on the appeal, the specific reasons for the
         decision, and the specific Plan provisions on which the decision is
         based. The notice of the decision shall be given within 60 days of the
         Claimant's written request for review, unless special circumstances
         (such as a hearing) would make the rendering of a decision within the
         60 day period infeasible, but in no event shall the Committee render a
         decision regarding the denial of a claim for benefits later than 120
         days after its receipt of a request for review. If an extension of time
         for review is required because of special circumstances, written notice
         of the extension shall be furnished to the claimant prior to the date
         the extension period commences.

         4.4      Designation of Beneficiaries. Each Participant shall designate
in a writing prescribed by the Committee a Beneficiary(ies) and contingent
Beneficiary(ies) to whom benefits due hereunder shall be paid. If any
Participant fails to designate a Beneficiary or if the designated Beneficiary
predeceases the Participant, benefits due hereunder at that Participant's death
shall be paid to his or her contingent Beneficiary or, if none, to the deceased
Participant's surviving spouse, if any, and if none, to the deceased
Participant's estate. Beneficiaries may be changed at any time by filing a new
Participation Agreement without the consent of any prior Beneficiaries.
Provided, however, that the Participant must designate his spouse as his
beneficiary or must obtain his spouse's written consent to the designation of
another beneficiary. Such spousal consent must be witnessed by the Committee or
a notary public. Any attempted designation of a beneficiary without the written
consent of the Participant's spouse shall be void. A Participant may change a
Beneficiary designation in writing in accordance with the above procedures at
any time prior to his death.


                                   V. BENEFITS

         5.1      Death Benefit. The Death Benefit will be paid to the
Beneficiaries of a Participant on the January 1 following the date of a
Participant's death.

         5.2      Normal Retirement Benefit. A Participant whose employment
terminates on or after the Normal Retirement Date shall begin receiving the
Normal Retirement Benefit on the Commencement Date. The Normal Retirement
Benefit shall be calculated as follows:

                  (a)      Prior to the occurrence of a Change in Control, the
         Normal Retirement Benefit shall be the sum of amounts that have been
         set aside or reserved through a "rabbi trust," insurance contract or
         any other funding medium that has been selected by the Company to fund
         benefits under the Plan.

                  (b)      After the occurrence of a Change in Control, the
         Normal Retirement Benefit shall be an annuity for life with a ten year
         term certain, with annual payments equal to: (the greater of (a) 55% or
         (b) 2.5% multiplied by the Participant's Years of Service)) multiplied
         by (the sum of the Participant's Compensation and the PhyCor Qualified
         Contributions) less (the Qualified Benefit).

         5.3      Early Retirement Benefit. A Participant whose employment
terminates prior to the Normal Retirement Date, other than as a result of
Disability, shall begin receiving the Early Retirement Benefit on January 1
following the Early Retirement Date.

         5.4      Disability Benefit. A Participant whose employment terminates
prior to the Normal Retirement Date as a result of Disability shall be entitled
to begin receiving the Normal Retirement Benefit on January 1 following the date
he attains the age of 60.


                                        6

<PAGE>   7



         5.5      Distribution After Termination of Employment. A Participant's
benefits hereunder will be paid as follows to the Participant or his
Beneficiary, if the Participant is deceased:

                  (a)      Generally, a payment of a Participant's benefit will
         commence on the Commencement Date and will be made in the form of a
         Normal Retirement Benefit, or, as appropriate, an Early Retirement
         Benefit or a Death Benefit.

                  (b)      The Committee may, in its absolute discretion, give
         its consent to any alternate payment election made by the Participant,
         provided that such consent is given on account of a change in PhyCor's
         business and/or financial considerations that the Committee deems
         appropriate. The decision of the Committee to consent or deny consent
         to a Participant's election described in this Section shall for all
         purposes be deemed to have been made pursuant to valid business or
         financial considerations.

                  (c)      Any payments that are made hereunder in a form other
         than the Normal Retirement Benefit shall be actuarially calculated to
         be equivalent to the Normal Retirement Benefit form by utilizing the
         interest rate and mortality assumptions that are specified in section
         417(e) of the Code, but without regard to pre-retirement mortality
         calculations and, provided further, that the interest rate utilized
         shall be the lowest rate available during the period for which the
         calculations are being made.

                  (d)      Notwithstanding the provisions of Section , following
         a Change in Control the Committee may not consent to or provide for a
         Plan distribution other than the payments described in Section without
         the approval of PhyCor (or its successor).


         5.6      Additional Change in Control Payments.

                  (a)      Anything in this Agreement to the contrary
         notwithstanding, in the event it shall be determined that any payment
         or distribution by or on behalf of PhyCor to or for the benefit of the
         Participant as a result of a change in control, as defined in Section
         280G of the Code, (whether paid or payable or distributed or
         distributable pursuant to the terms of this Agreement or otherwise, but
         determined without regard to any additional payments required under
         this Section (a "Payment")) would be subject to the excise tax imposed
         by Section 4999 of the Code, or any interest or penalties are incurred
         by the Participant with respect to such excise tax (such excise tax,
         together with any such interest and penalties, are hereinafter
         collectively referred to as the "Excise Tax"), then the Participant
         shall be entitled to receive an additional payment (a "Gross-Up
         Payment") in an amount such that after payment by the Participant of
         all taxes (including any interest or penalties imposed with respect to
         such taxes), including, without limitation, any income taxes (and any
         interest and penalties imposed with respect thereto) and Excise Tax
         imposed upon the Gross-Up Payment, the Participant retains an amount of
         the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

                                        7

<PAGE>   8




                  (b)      Subject to the provisions of Section , all
         determinations required to be made under this Section , including
         whether and when a Gross-Up Payment is required and the amount of such
         Gross-Up Payment and the assumptions to be utilized in arriving at such
         determination, shall be made by a nationally recognized accounting firm
         selected by the Participant, subject to the consent of PhyCor, which
         consent shall not be unreasonably withheld (the "Accounting Firm");
         provided, however, that the Accounting Firm shall not determine that no
         Excise Tax is payable by the Participant unless it delivers to the
         Participant a written opinion (the "Accounting Opinion") that failure
         to pay the Excise Tax and to report the Excise Tax and the payments
         potentially subject thereto on or with the Participant's applicable
         federal income tax return will not result in the imposition of an
         accuracy-related or other penalty on the Participant. All fees and
         expenses of the Accounting Firm shall be borne solely by PhyCor. Within
         15 business days of the receipt of notice from the Participant that
         there has been a Payment, or such earlier time as is requested by
         PhyCor, the Accounting Firm shall make all determinations required
         under this Section , shall provide to PhyCor and the Participant a
         written report setting forth such determinations, together with
         detailed supporting calculations, and, if the Accounting Firm
         determines that no Excise Tax is payable, shall deliver the Accounting
         Opinion to the Participant. Any Gross-Up Payment, as determined
         pursuant to this Section , shall be paid by PhyCor to the Participant
         within fifteen days of the receipt of the Accounting Firm's
         determination. Subject to the remainder of this Section , any
         determination by the Accounting Firm shall be binding upon PhyCor and
         the Participant; provided, however, that the Participant shall only be
         bound to the extent that the determinations of the Accounting Firm
         hereunder, including the determinations made in the Accounting Opinion,
         are reasonable and reasonably supported by applicable law. As a result
         of the uncertainty in the application of Section 4999 of the Code at
         the time of the initial determination by the Accounting Firm hereunder,
         it is possible that Gross-Up Payments which will not have been made by
         PhyCor should have been made ("Underpayment"), consistent with the
         calculations required to be made hereunder. In the event that it is
         ultimately determined in accordance with the procedures set forth in
         Section that the Participant is required to make a payment of any
         Excise Tax, the Accounting Firm shall reasonably determine the amount
         of the Underpayment that has occurred and any such Underpayment shall
         be promptly paid by PhyCor to or for the benefit of the Participant. In
         determining the reasonableness of Accounting Firm's determinations
         hereunder, and the effect thereof, the Participant shall be provided a
         reasonable opportunity to review such determinations with Accounting
         Firm and the Participant's tax counsel. Accounting Firm's
         determinations hereunder, and the Accounting Opinion, shall not be
         deemed reasonable until the Participant's reasonable objections and
         comments thereto have been satisfactorily accommodated by Accounting
         Firm.

                  (c)      The Participant shall notify PhyCor in writing of any
         claims by the Internal Revenue Service that, if successful, would
         require the payment by PhyCor of the Gross-Up Payment. Such
         notification shall be given as soon as practicable but no later than 30
         calendar days after the Participant actually receives notice in writing
         of such

                                        8

<PAGE>   9



         claim and shall apprise PhyCor of the nature of such claim and the date
         on which such claim is requested to be paid; provided, however, that
         the failure of the Participant to notify PhyCor of such claim (or to
         provide any required information with respect thereto) shall not affect
         any rights granted to the Participant under this Section except to the
         extent that PhyCor is materially prejudiced in the defense of such
         claim as a direct result of such failure. The Participant shall not pay
         such claim prior to the expiration of the 30-day period following the
         date on which he gives such notice to PhyCor (or such shorter period
         ending on the date that any payment of taxes with respect to such claim
         is due). If PhyCor notifies the Participant in writing prior to the
         expiration of such period that it desires to contest such claim, the
         Participant shall:

                           (1)      give PhyCor any information reasonably
                  requested by PhyCor relating to such claim;

                           (2)      take such action in connection with
                  contesting such claim as PhyCor shall reasonably request in
                  writing from time to time, including, without limitation,
                  accepting legal representation with respect to such claim by
                  an attorney selected by PhyCor and reasonably acceptable to
                  the Participant;

                           (3)      cooperate with PhyCor in good faith in order
                  effectively to contest such claim; and

                           (4)      if PhyCor elects not to assume and control
                  the defense of such claim, permit PhyCor to participate in any
                  proceedings relating to such claim;

         provided, however, that PhyCor shall bear and pay directly all costs
         and expenses (including additional interest and penalties) incurred in
         connection with such contest and shall indemnify and hold the
         Participant harmless, on an after-tax basis, for any Excise Tax or
         income tax (including interest and penalties with respect thereto)
         imposed as a result of such representation and payment of costs and
         expenses. Without limiting the foregoing provisions of this Section ,
         PhyCor shall have the right, at its sole option, to assume the defense
         of and control all proceedings in connection with such contest, in
         which case it may pursue or forego any and all administrative appeals,
         proceedings, hearings and conferences with the taxing authority in
         respect of such claim and may either direct the Participant to pay the
         tax claimed and sue for a refund or contest the claim in any
         permissible manner, and the Participant agrees to prosecute such
         contest to a determination before any administrative tribunal, in a
         court of initial jurisdiction and in one or more appellate courts, as
         PhyCor shall determine; provided, however, that if PhyCor directs the
         Participant to pay such claim and sue for a refund, PhyCor shall
         advance the amount of such payment to the Participant, on an
         interest-free basis and shall indemnify and hold the Participant
         harmless, on an after-tax basis, from any Excise Tax or income tax
         (including interest or penalties with respect thereto) imposed with
         respect to such advance or with respect to any imputed income with
         respect to such advance; and further provided that any extension of the
         statute of limitations

                                        9

<PAGE>   10



         relating to payment of taxes for the taxable year of the Participant
         with respect to which such contested amount is claimed to be due is
         limited solely to such contested amount. Furthermore, PhyCor's right to
         assume the defense of and control the contest shall be limited to
         issues with respect to which a Gross-Up Payment would be payable
         hereunder and the Participant shall be entitled to settle or contest,
         as the case may be, any other issue raised by the Internal Revenue
         Service or any other taxing authority.

                  (d)      If, after the receipt by the Participant of an amount
         advanced by PhyCor pursuant to Section the Participant becomes entitled
         to receive any refund with respect to such claim, the Participant shall
         (subject to PhyCor's complying with the requirements of Section )
         promptly pay to PhyCor the amount of such refund (together with any
         interest paid or credited thereon after taxes applicable thereto). If,
         after the receipt by the Participant of an amount advanced by PhyCor
         pursuant to Section , a determination is made that the Participant is
         not entitled to a refund with respect to such claim and PhyCor does not
         notify the Participant in writing of its intent to contest such denial
         of refund prior to the expiration of 30 days after such determination,
         then such advance shall, to the extent of such denial, be forgiven and
         shall not be required to be repaid and the amount of forgiven advance
         shall offset, to the extent thereof, the amount of Gross-Up Payment
         required to be paid.


                           VI. FORFEITURE OF BENEFITS

         6.1      Noncompete Violation. A Participant who violates the
non-competition provision contained in his Employment Agreement shall forfeit
his right to any and all benefits under this Plan.

         6.2      For Cause Termination. A Participant who is terminated "for
cause," as herein defined, shall forfeit his right to any and all benefits under
this Plan. Termination "for cause" shall mean termination upon:

                  (a)      the Participant's final conviction of a felony crime
         involving moral turpitude, or the Participant's deliberate and
         intentional continuing refusal to substantially perform his duties and
         obligations under his employment (except by reason of incapacity due to
         illness or accident) if he shall have either failed to remedy such
         alleged breach within 45 days from his receipt of written notice from
         PhyCor demanding that he remedy such alleged breach, or shall have
         failed to take reasonable steps in good faith to that end during such
         45 day period and thereafter; or

                  (b)      a determination that the Participant has engaged in
         willful fraud and defalcation or other dishonesty involving the funds,
         assets or the operation of PhyCor.

         6.3      Effect of Change in Control. The occurrence of a Change in
Control shall not result in any acceleration of vesting of benefits or the
removal of any conditions of forfeiture.

                                       10

<PAGE>   11



However, all determinations under the Plan, including a determination under this
Article , shall be made by the Committee as it is configured following a Change
in Control pursuant to Section .


                               VII. MISCELLANEOUS

         7.1.     Non-assignment of Interest. No right or interest to or in any
payment or benefit to a Participant shall be assignable by such Participant
except by will or the laws of descent and distribution. No right, benefit or
interest of a Participant hereunder shall be subject to anticipation,
alienation, sale, assignment, encumbrance, charge, pledge, hypothecation or
set-off in respect of any claim, debt or obligation, or to execution,
attachment, levy or similar process, or assignment by operation of law. Any
attempt, voluntarily or involuntarily, to effect any action specified in the
immediately preceding sentence shall, to the full extent permitted by law, be
null, void and of no effect; provided, however, that this provision shall not
preclude a Participant from designating one or more Beneficiaries to receive any
amount that may be payable to such Participant under the Plan after his death
and shall not preclude the legal representatives of the Participant's estate
from assigning any right hereunder to the person or persons entitled thereto
under his will, or, in the case of intestacy, to the person or persons entitled
thereto under the laws of intestacy applicable to his estate.

         7.2      Successors. This Plan shall be binding upon and inure to the
benefit of PhyCor, its successors and assigns and the Participants and their
heirs, executors, administrators, duly appointed legal representatives.

         7.3      Amendment and Termination. PhyCor may at any time modify or
terminate this Plan by an amendment pursuant to an action that is approved or
ratified by PhyCor's board of directors. Provided, however, that amendments that
would reduce benefits or rights of an individual who is a Participant at the
time of the amendment shall not be binding with respect to such Participant
without the Participant's prior written consent.

         7.4      Taxes. All payments made hereunder shall be subject to all
taxes required to be withheld under applicable laws and regulations of any
governmental authorities in effect at the time of such payments.

         7.5      Controlling Law. Except to the extent superseded by federal
law, the internal laws of the State of Tennessee shall be controlling in all
materials relating to the Plan, including construction and performance hereof.

                         INDEPENDENT AUDITORS' REPORT





The Board of Directors and Shareholders
PhyCor, Inc.:


     We have audited the consolidated balance sheets of PhyCor, Inc.
and subsidiaries as of December 31, 1997 and 1996 and the related
consolidated statements of income, shareholders' equity and cash flows
for each of the years in the three-year period ended December 31, 1997.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audits.

     We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for
our opinion.

     In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial position
of PhyCor, Inc. and subsidiaries as of December 31, 1997 and 1996, 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 Consolidated Financial Statements

                        December 31, 1997, 1996, and 1995


(1)    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PRACTICES

       (A)    DESCRIPTION OF BUSINESS

              PhyCor, Inc. (Company) is a physician practice management company
              that acquires and operates multi-specialty medical clinics and
              develops and manages independent practice associations ("IPAs").
              PhyCor's objective is to organize physicians into professionally
              managed networks that assist physicians in assuming increased
              responsibility for delivering cost-effective medical care while
              attaining high-quality clinical outcomes and patient satisfaction.
              The Company, through wholly-owned subsidiaries, acquires certain
              assets of and operates clinics under long-term service agreements
              with affiliated physician groups that practice exclusively through
              such clinics. The Company provides administrative and technical
              support for professional services rendered by the physician groups
              under service agreements. Under most service agreements, the
              Company is reimbursed for all clinic expenses, as defined in the
              agreement, and participates at varying levels in the excess of net
              clinic revenue over clinic expenses. As of December 31, 1997, the
              Company operated 55 clinics in 28 states.

              The Company also manages IPAs which are networks of independent
              physicians. Fees earned from managing the IPAs are based upon a
              percentage of revenue collected by the IPAs and also upon a share
              of surplus, if any, of capitated revenue of the IPAs. At December
              31, 1997, these IPAs include over 19,000 physicians in 28 markets
              which provide capitated medical services to approximately
              1,132,000 members, including approximately 174,000 Medicare
              members.

       (B)    PRINCIPLES OF CONSOLIDATION

              The consolidated financial statements include the accounts of the
              Company and its majority owned subsidiaries, partnerships and
              other entities in which the company has more than 50% ownership
              interest or exercises control. All significant intercompany
              balances and transactions are eliminated in consolidation. The
              Company does not consolidate the physician practices it manages as
              it does not have operating control as defined in EITF 97-2,
              "Application of APB Opinion No. 16 and FASB Statement No. 94 to
              Physician Practice Entities."

       (C)    CASH AND CASH EQUIVALENTS

              The Company considers all highly liquid investments with a
              maturity of three months or less when purchased to be cash
              equivalents. Cash and cash equivalents as of December 31, 1997
              include approximately $2,943,000 of consolidated partnership cash.
              These balances may only be used for the operations of the
              respective partnerships.

       (D)    ACCOUNTS RECEIVABLE

              Accounts receivable principally represent receivables from
              patients and third-party payors for medical services provided by
              physician groups. Terms of the service agreements require the
              Company to purchase receivables generated by the physician groups
              on a monthly basis. Such amounts are recorded net of contractual
              allowances and estimated bad debts. Accounts receivable are a
              function of net clinic revenue rather than net revenue of the
              Company (See note 2).

                                                                     (Continued)

                   Notes to Consolidated Financial Statements




(E)    INVENTORIES

       Inventories are comprised primarily of medical supplies,
       medications and other materials used in the delivery of health
       care services by the physician groups at the Company's clinics.
       The Company values inventories at the lower of cost or market with
       cost determined using the first-in, first-out (FIFO) method.

(F)    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 of
       property and equipment is calculated using the straight-line
       method over the estimated useful lives of the assets. Equipment
       held under capital leases and leasehold improvements are amortized
       on a straight line basis over the shorter of the lease term or
       estimated useful life of the assets.

(G)    INTANGIBLE ASSETS

       CLINIC SERVICE AGREEMENTS

       Costs of obtaining clinic service agreements are amortized using
       the straight-line method over the periods during which the
       agreements are effective, currently twenty-five to forty years.
       Clinic service agreements represent the exclusive right to operate
       the Company's clinics in affiliation with the related physician
       groups during the term of the agreements. In the event of
       termination of a service agreement, the related physician group is
       required to purchase all clinic assets, including the unamortized
       portion of intangible assets, generally at then current net book
       value.

       EXCESS OF COST OF ACQUIRED ASSETS OVER FAIR VALUE

       Excess of cost of acquired assets over fair value (goodwill) is
       amortized using the straight line method over thirty years.

       OTHER INTANGIBLE ASSETS

       Other intangible assets include costs associated with obtaining
       long-term financing which are being amortized systematically over
       the terms of the related debt agreements.

       AMORTIZATION AND RECOVERABILITY

       The Company periodically reviews its intangible assets to assess
       whether recoverability and impairments would be recognized in the
       statement of operations if a permanent impairment were determined
       to have occurred. Recoverability of intangibles is determined
       based on undiscounted future operating cash flows from the related
       business unit or activity. The amount of impairment, if any, is
       measured based on discounted future operating cash flows using a
       discount rate reflecting the Company's average cost of funds or
       based on the fair value of the related business unit or activity.
       The assessment of the recoverability of intangible assets will be
       impacted if estimated future operating cash flows are not
       achieved. Amortization of intangibles amounted to $23,865,000,
       $15,150,000, and $7,441,000, and for 1997, 1996 and 1995,
       respectively.

(H)    IMPAIRMENT OF LONG-LIVED ASSETS

       The Company reviews long-lived assets and certain identifiable
       intangibles for impairment whenever events or changes in
       circumstances indicate that the carrying amount of an asset may
       not be recoverable. Recoverability of assets to be held and used
       is measured by a comparison of the carrying amount of an asset to
       future net cash flows expected to be generated by the asset. If
       such assets are considered to be impaired, the impairment to be
       recognized is measured by the amount by which the carrying amount
       of the assets exceeded the fair value of the assets.

(I)    INCOME TAXES

       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 the tax rates
       is recognized in income in the period that includes the enactment
       date.

(J)    FINANCIAL INSTRUMENTS

       In 1997, the Company entered into an interest rate swap agreement
       to reduce the exposure to fluctuating interest rates with respect
       to $100,000,000 of its bank credit facility. The interest rate
       swap agreement matures in October 2002, with a lender's option to
       terminate beginning October 1999, and is accounted for on the
       accrual method. Gains and losses resulting from this instrument
       are recognized in the same period as the related interest expense.
       Gains and losses are included in interest expense. The Company
       does not use interest rate swap agreements or other derivative
       financial instruments for speculative or trading purposes.

                   Notes to Consolidated Financial Statements



       (K)    STOCK OPTION PLANS

              The Company accounts for its compensation and stock option plans
              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. In accordance
              with SFAS No. 123, Accounting for Stock-Based Compensation (SFAS
              No. 123), the Company provides pro forma net income 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.

       (L)    EARNINGS PER SHARE

              The Company adopted Statement of Financial Accounting Standards
              No. 128, Earnings Per Share, in 1997. This statement requires that
              a dual presentation of both Basic and Diluted earnings per share.
              Basic earnings per share is computed based on weighted average
              shares outstanding and excludes any potential dilution. Diluted
              earnings per share reflects the potential dilution from the
              exercise or conversion of all dilutive securities into common
              stock based on the average market price of common shares
              outstanding during the period. All periods presented have been
              restated to conform with the provisions of the new statement.

       (M)    USE OF ESTIMATES

              Management of the Company has made certain estimates and
              assumptions relating to the reporting of assets and liabilities
              and the disclosure of contingent assets and liabilities to prepare
              these consolidated financial statements in conformity with
              generally accepted accounting principles. Actual results could
              differ from those estimates.

       (N)    RECLASSIFICATIONS

              Certain  prior year amounts have been reclassified to conform to
              the 1997 presentation.

(2)    NET REVENUE

       Clinic service agreement revenue is equal to the net revenue of the
       clinics, less amounts retained by physician groups. Net clinic revenue is
       recorded by the physician groups at established rates reduced by
       provisions for doubtful accounts, contractual adjustments and amounts
       retained by physician groups. Contractual adjustments arise due to the
       terms of certain reimbursement and managed care contracts. Such
       adjustments represent the difference between charges at established rates
       and estimated recoverable amounts and are recognized in the period the
       services are rendered. Any differences between estimated contractual
       adjustments and actual final settlements under reimbursement contracts
       are recognized as contractual adjustments in the year final settlements
       are determined. The physician groups, rather than the Company, enter into
       managed care contracts. Through calculation of its service fees, the
       Company shares indirectly in any capitation risk assumed by its
       affiliated physician groups.

       IPA management revenue is equal to the difference between the amount of
       capitation and risk pool payments due to the IPA's managed by the
       Company, less amounts retained by the IPA.

  

                                                                     (Continued)

</TABLE>

The Company derives most of its net revenue from 55 physician groups located in
28 states with which it has service agreements at December 31, 1997. The
Company's affiliated physician groups derived approximately 20% of their net
revenues from services provided under the Medicare program for the years ended
December 31, 1997, 1996 and 1995. Other than the Medicare program, the physician
groups have no customers which represent more than 10% of aggregate net clinic
revenue or 5% of accounts receivables at December 31, 1997 and 1996.

         agreement between November 1, 1995 and December 31, 1995. Effective
         January 1, 1996 the Company completed the purchase of certain clinic
         operating assets and entered into a long-term service agreement with

         five years and agreed, pending satisfaction of certain conditions, to
         acquire certain assets of the clinic prior to the termination or
         expiration of the interim management agreement.

         In addition, the Company acquired certain operating assets of various
         individual physician practices and single specialty groups which were
         merged into clinics already operated by the Company.

The Company acquires operating assets and liabilities in exchange for cash,
convertible debentures, common stock or a combination thereof. Such
consideration for the above clinic acquisitions and single specialty mergers was
$430,757,000 for 1997, $357,458,000 for 1996, and $239,620,000 for 1995. The
acquisitions were accounted for as purchases, and the accompanying consolidated
financial statements include the results of their operations from the dates of
acquisition. Simultaneous with each acquisition, the Company entered into a
long-term service agreement with each physician group. In conjunction with
certain acquisitions, the Company is obligated at December 31, 1997 to make
deferred payments to physician groups of which $100,988,000 are due on demand or
within one year and $18,366,000, $4,300,000, and $879,000 are due in 1999, 2000,
and 2001, respectively. Such payments are included in purchase price payable in

       In June 1995, the Company purchased a minority interest of approximately
       9% in PMC and manages PMC pursuant to a 10-year administrative services
       agreement. PMC develops and manages IPA's and provides other services to

       will be approximately $23,000,000 and paid in shares of the Company's
       common stock. In connection with the PMC transaction, the Company
       established a revolving line of credit of $2,000,000 for PMC for a period
       of five years of which $1,550,000 was outstanding as of December 31, 1997
       and none was outstanding at December 31, 1996.

(7)    FAIR VALUE OF FINANCIAL INSTRUMENTS

       As of December 31, 1997 and 1996, the fair value of the Company's cash
       and cash equivalents, accounts receivable, accounts payable, due to
       physician groups, and accrued expenses approximated their carrying value
       because of the short maturities of those financial instruments. The fair
       value of the Company's long-term debt also approximates its carrying
       value since the related notes bear interest at current market rates.

       The estimated fair value of the convertible subordinated notes payable to
       physician groups was approximately $65,218,000 and $102,723,000 as of
       December 31, 1997 and 1996, respectively. The carrying value of these
       notes was approximately $61,576,000 and $83,918,000 at December 31, 1997
       and 1996, respectively. The estimated fair value of these convertible
       securities is based on the greater of their face value and the closing
       market value of the common shares into which they could have been
       converted at the respective balance sheet date. The estimated fair value
       of the Company's convertible subordinated debentures was $195,000,000 and
       $198,000,000 as of December 31, 1997 and 1996, respectively, compared to
       a carrying value of $200,000,000. The estimated fair value of these
       convertible debentures is based on current market indicators or quotes
       from brokers.

(8)    CONVERTIBLE SUBORDINATED NOTES PAYABLE TO PHYSICIAN GROUPS

       At December 31, 1997 and 1996, the Company had outstanding subordinated
       convertible notes payable to affiliated physician groups in the aggregate
       principal amount of approximately $61,576,000 and $83,918,000,
       respectively. These notes bear interest at rates of 5.84% to 7.0% and are
       convertible into shares of the Company's common stock at conversion
       prices ranging from $9.59 to $57.78 per share. A convertible subordinated
       note of $33,295,000 issued in connection with the Guthrie Clinic
       transaction will be convertible into approximately 903,000 shares of
       common stock upon the Company's acquisition of the clinic's assets prior
       to November 17, 2005. If the then current price of the common stock is
       less than the conversion price, PhyCor will pay the clinic the principal
       amount of the note. The remaining convertible notes may be converted into
       approximately 1,263,000 shares of common stock, with 648,000 shares
       convertible at December 31, 1997 and 615,000 shares convertible
       commencing on varying dates in 1998 through 2002 at the option of the
       holders.

                                                                     (Continued)

(9)    CONVERTIBLE SUBORDINATED DEBENTURES

       At December 31, 1994, the Company had $28,655,000 of convertible
       subordinated debentures outstanding. The debentures had a coupon rate of
       6.5% and were convertible into the Company's common stock at $5.87 per
       share. The Company called for redemption effective January 20, 1995, all
       outstanding debentures at a redemption price of 105.2% of par value plus
       accrued interest. In January 1995, prior to the redemption date, the
       debentures were converted into common stock of the Company.

       During February 1996, the Company completed a public offering of
       convertible subordinated debentures, which mature in 2003. Gross and net
       proceeds from the offering were $200,000,000 and approximately
       $194,395,000, respectively. The debentures were priced at par with a
       coupon rate of 4.5% and are convertible into the Company's common stock
       at $38.67 per share. The debentures may not be redeemed at the Company's
       option prior to February 15, 1998. From February 15, 1998 to February 15,
       1999, the bonds may be redeemed only if the price of the Company's common
       stock exceeds $54.13. From February 15, 1999 to maturity, the bonds may
       be redeemed at prices decreasing from 102.572% of face value to face
       value.

       (D)    1988 STOCK INCENTIVE PLAN AND DIRECTORS' STOCK PLAN

              The Company has two stock option plans. Under the Amended 1988
              Incentive Stock Plan ("Incentive Plan"), the Company has reserved
              17,000,000 shares of its common stock for issuance pursuant to
              option and stock grants to employees and directors. Under the
              Amended 1992 Directors Stock Plan ("Directors Plan"), 337,500
              shares of common stock are reserved. Under both plans, stock
              options are granted with an exercise price equal to the estimated
              fair market value of the Company's common stock on the date of
              grant. All options have a term of ten years and become exercisable
              in installments over periods ranging up to five years. In addition
              to options granted under the two plans, the Company has granted
              options for the purchase of 25,313 shares of its common stock to a
              director of the Company and a consultant.

              At December 31, 1997, there were approximately 2,758,000 and
              134,000 additional shares available for grant under the Incentive
              Plan and the Directors Plan, respectively.

              The per share weighted-average fair value of stock options granted
              during 1997, 1996 and 1995 was $15.18, $16.97, and $9.25 on the
              date of grant using the Black Scholes option-pricing model with
              the following assumptions: an expected dividend yield of 0.0% for
              all years, expected volatility of 56% in 1997 and 1996, and 43% in
              1995, risk-free interest rate ranging from 5.88% to 6.63% in 1997,
              5.25% to 6.63% in 1996 and 5.50% to 7.75% in 1995, and an expected
              life of five years for all years.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements




The Company applies APB Opinion No. 25 in accounting for its Plans and,
accordingly, no compensation cost has been recognized for its stock options in
the financial statements. Had the Company determined compensation cost based on
the fair value at the grant date for its stock options under SFAS No. 123, the
Company's net income would have been reduced to the pro forma amounts indicated
below (in thousands except for earnings per share):

Pro forma net income reflects only options granted beginning in 1995. Therefore,
the full impact of calculating compensation cost for stock options under SFAS
No. 123 is not reflected in the pro forma net income amounts presented above
because compensation cost is reflected over the options' vesting period and
compensation cost for options granted prior to January 1, 1995 is not
considered.

Stock option activity during the periods indicated is as follows (shares in
thousands):

                   Notes to Consolidated Financial Statements




At December 31, 1997, the range of exercise prices and weighted-average
remaining contractual life of outstanding options was $2.97 - $38.33 and 8.16
years, respectively.

At December 31, 1997, 1996, and 1995, the number of options exercisable was
2,268,000, 1,392,000, and 854,000, respectively, and the weighted-average
exercise price of those options was $7.02, $5.23, and $4.15, respectively.

(E) STOCK PURCHASE PLANS 

The Company has reserved 843,750 common shares for issuance pursuant to its
employee stock purchase plan. During 1997 and 1996, approximately 82,000 and
110,000 shares were issued relative to the plan. Shares issued under the
employee stock purchase plan will generally be priced at the lower of 85% of the
fair market value of the Company's common stock on the first or the last trading
days of the plan year.

The Company also established the 1996 Affiliate Stock Purchase Plan and has
reserved 2,250,000 common shares for this plan. Eligible participants generally
include physicians and other employees of medical clinics with which the Company
has a management or service agreement and employees of limited liability
companies and partnerships in which the Company has an equity interest of at
least 50%. Shares issued under the plan will be priced using a similar method as
that of the employee stock purchase plan. During 1997, approximately 343,000
shares were issued under this plan and no shares were issued in 1996.

Pro forma compensation expense included in the pro forma calculation above is
recognized for the fair value of each stock purchase right estimated on the date
of grant using the Black Scholes pricing model. The following assumptions were
used for stock purchases: an expected dividend yield of 0.0% for all years,
expected volatility of 56% in 1997 and 1996, risk-free interest rate of 6.0% in
1997 and 6.25% in 1996 and an expected life of one year for all years.

Options and warrants to purchase 162,000 and 18,000 shares of common stock were
outstanding during 1997 and 1996, respectively, but were not included in the
computation of diluted EPS because the options' exercise price was greater than
the average market price of the common shares, resulting in the options being
antidilutive. Interest paid on the convertible notes is offset by service
agreement fees received by the Company of an equal amount.

(13)   NONRECURRING CHARGE

The following table sets forth the components of the nonrecurring charge:

                                                                            -----------

</TABLE>


The Company determined to dispose of certain clinics in the fourth quarter of
1997 due to circumstances arising in that quarter that indicated to the Company
that those clinics could not be operated at an acceptable profit level. The
Company expects to dispose of the assets and service agreements related to such
clinics in 1998. Clinic net assets to be disposed of totaling $3,237,000 have
been included in prepaid expense and other current assets. Net losses from the
clinics to be disposed of totaled $666,000 in 1997.

In addition, the Company reviewed certain of its clinics, consistent with SFAS
121, when specific events occurred in the fourth quarter that indicated that the
individual clinics involved could be impaired (i.e. physician group declared
bankruptcy, notifications of physician termination, etc.). The Company
determined that an impairment had occurred and wrote down the associated clinic
assets and service agreement intangibles to fair value determined by discounting
future operating cash flows of the related physician groups.

                   Notes to Consolidated Financial Statements



For federal income tax purposes, the Company receives a deduction arising from
the exercise of non-qualified stock options equal to the difference between the
fair market value at date of exercise and the exercise price. This tax benefit
was recorded as a credit to common stock in the amount of $5,464,000,
$2,940,000, and $625,000 in 1997, 1996, and 1995, respectively.

Total income tax expense differed from the amount computed by applying the U.S.
federal income tax rate of 35 percent in 1997, 1996, and 1995 to earnings before
income taxes as a result of the following (in thousands):

       The significant components of the deferred tax expense as of December
       31, 1997 and 1996 are as follows (in thousands):

</TABLE>

       The net change in the total valuation allowance for the year ended
       December 31, 1997, which primarily relates to federal and state net
       operating loss carryforwards and expenses relating to the nonrecurring
       charge not expected to be deductible for state tax purposes, was an
       increase of $8,874,000. As of December 31, 1997, the Company had
       approximately $6,950,000 of federal and $118,034,000 of state net
       operating loss carryforwards which begin to expire in 2007. The
       utilization of these carryforwards is subject to the future level of
       taxable income of the applicable subsidiaries.

       The Company has been the subject of an audit by the IRS since 1991, and
       the IRS has proposed adjustments relating to the timing of recognition
       for tax purposes of certain revenue and deductions relating to
       uncollectable accounts. PhyCor disagrees with the positions asserted by
       the IRS and is vigorously contesting these proposed adjustments. The
       Company believes that any adjustments resulting from resolution of this
       disagreement would not affect reported net earnings of PhyCor but would
       defer tax benefits and change the levels of current and deferred tax
       assets and liabilities.

(15)   EMPLOYEE BENEFIT PLANS

       As of January 1, 1989, the Company adopted the PhyCor, Inc. Savings and
       Profit Sharing Plan. The Plan is a defined contribution plan covering
       substantially all employees. Company contributions are based on specified
       percentages of employee compensation. The Company funds contributions as
       accrued. The contributions for 1997, 1996, and 1995 amounted to
       $10,245,000, $7,803,000, and $3,976,000, respectively.

       In connection with certain of the Company's acquisitions, the Company
       adopted employee retirement plans previously sponsored solely by the
       physician groups. The Company has recognized as expense its required
       contributions to be made to the plans of approximately $4,789,000,
       $3,174,000, and $1,248,000 relative to its employees for 1997, 1996, and
       1995, respectively.


                                                                     (Continued)

(16)   COMMITMENTS AND CONTINGENCIES

       (A)   EMPLOYMENT AGREEMENTS

              The Company has entered into employment agreements with certain of
              its management employees, which include, among other terms,
              noncompete provisions and salary and benefits continuation.

       (B)   COMMITMENTS TO PHYSICIAN GROUPS

              Under terms of certain of its service agreements, the Company is
              committed to provide capital for the improvement and expansion of
              clinic facilities. The commitments vary depending on such factors
              as total capital expenditures, the number of physicians practicing
              at each clinic, and the cost of specific planned projects. All
              projects funded under these commitments must be approved by the
              Company before they commence.

              The Company is also committed to provide, under certain
              circumstances, advances to physician groups to principally finance
              the recruitment of new physicians. These advances will be repaid
              out of the physician groups' share of future clinic revenue. At
              December 31, 1997 and 1996, $4,038,000, and $2,230,000,
              respectively, of such advances were outstanding.

        (C)   LITIGATION

              The Company is subject to various claims and legal actions which
              arise in the ordinary course of business, certain of which could
              be material. In the opinion of management, the ultimate resolution
              of such matters will be adequately covered by the insurance and
              will not have a material adverse effect on the Company's financial
              position, results of operations or liquidity.

        (D)   INSURANCE

              The Company and its affiliated physician groups are insured with
              respect to medical malpractice risks on a claims-made basis. There
              are known claims and incidents that may result in the assertion of
              additional claims, as well as claims from unknown incidents that
              may be asserted. Management is not aware of any claims against it
              or its affiliated physician groups which might have a material
              impact on the Company's financial position.

        (E)   CONTINGENT CONSIDERATION

              In connection with the acquisition of clinic operating assets, the
              Company is contingently obligated to pay an estimated additional
              $83,000,000 in future years, depending on the achievement of
              certain financial and operational objectives by the related
              physician groups. Such liability, if any, will be recorded in the
              period in which the outcome of the contingency becomes known. Any
              payment made will be allocated among the assets acquired and will
              not immediately be charged to expense.
