ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

       Effective August 4, 1998, AmSurg Westlake, Inc. ("AmSurg"), a subsidiary
of AmSurg Corp. (the "Company") acquired from Michael Kaslow, M.D., a
Professional Corporation, George S. Hoffman, M.D., a Professional Corporation,
Michael Kaslow, M.D., George S. Hoffman, M.D., John J. Darin, M.D., Henry Curry,

ownership interest in the assets comprising the business operations of an
ophthalmic ambulatory surgery center (the "Center") in Westlake Village,
California.

       Pursuant to the terms of the Asset Purchase Agreements, dated as of
August 4, 1998, by and among AmSurg and the Sellers, AmSurg and the Company paid
$1,792,823 in cash and 23,571 shares of Class A Common Stock, valued at

Bank, Nashville and NationsBank of Tennessee. The consideration paid to the
Sellers was determined through arm's-length negotiations between the Company and
the Sellers. Following the asset purchase, AmSurg and Westlake Eye Surgery

interests in the assets of the Center into a newly formed partnership, The

ASSET PURCHASE AGREEMENT
- -------------------------------------------------------------------------------


         THIS ASSET PURCHASE AGREEMENT (the "Agreement"), dated August 4, 1998,
is by and among AmSurg Westlake, Inc., a Tennessee corporation ("AmSurg"),
Westlake Eye Surgery Center, a California partnership ("Westlake"), Michael
Kaslow, M.D., a Professional Corporation ("Seller"), and the individual set
forth on the signature pages attached hereto ("Doctor").

         WHEREAS, AmSurg desires to purchase and Seller desires to sell certain
of its assets, as more fully described herein, upon and subject to the terms and
conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties and covenants of the parties hereinafter set forth,
the parties agree as follows:

ARTICLE 1.        PURCHASE AND SALE OF ASSETS

         1.1. PURCHASE AND SALE OF ASSETS. Subject to the terms and conditions
of this Agreement, at the Closing, Seller shall sell, transfer, convey, assign
and deliver to AmSurg and AmSurg shall purchase, acquire and accept from Seller
an undivided 3% interest in the assets comprising the business operations of the
ophthalmic ambulatory surgery center (the "Center") owned and operated by
Westlake and located in Westlake Village, California, tangible or intangible,
recorded or unrecorded, known or unknown, of whatsoever type, kind, description,
or nature owned, leased, held, possessed, vested in or claimed in whole or in
part by Seller on the Closing Date (the "Purchased Assets"), which Purchased
Assets shall specifically include the accounts receivable of the Center, but
which shall specifically exclude cash and the account receivable from Westlake
Laser Surgery Center in the approximate amount of $47,656.

         1.2. ASSUMPTION OF LIABILITIES. Except as described in Schedule 1.2,
AmSurg will not assume any debts, liabilities, obligations, expenses, taxes,
contracts or commitments of Seller, Westlake, Doctor or the Center of any kind,
character or description, whether accrued, absolute, contingent or otherwise
("Liabilities"), no matter whether arising before or after the Closing, and
whether or not reflected or reserved against in Seller's, Westlake's, Doctor's
or the Center's financial statements, books of account or records. Westlake,
Seller and Doctor will indemnify AmSurg against and hold it harmless from any
such Liabilities. AmSurg will cause The Westlake Ophthalmology ASC, L.P., a
Tennessee limited partnership (the "Partnership"), to assume all Liabilities
arising after the effective date of the transaction which relate to supplies
received by the Center or services rendered to the Center after the effective
date of the transaction, regardless of the date such Liabilities arose.

ARTICLE 2.        PURCHASE PRICE

         The initial purchase price of the Purchased Assets (the "Initial
Purchase Price") shall be $102,594.00 in cash.

         AmSurg and Seller acknowledge that the rule proposed in June 1998 by
the Health Care Financing Administration ("HCFA") providing in part for a change
in the payment rates utilized by HCFA to reimburse ambulatory surgery centers as
it may be adopted or amended (the "proposed Rule"), could have a negative effect
on the future revenues and earnings of the Center. In order to address the
uncertainty regarding the Proposed Rule and its effect on the Center, the
Initial Purchase Price has been calculated based on the financial statements for
the Center for the calendar year 1997 and the annualized procedure volume for
Medicare cases performed in the Center from January 1, 1998 through May 31,
1998, as set forth in Exhibit 2(a). Exhibit 2(b) sets forth what the purchase
price would have been without any adjustment for the proposed Medicare
reimbursement rate changes (the "Potential Purchase Price"). The difference
between the Initial Purchase Price and the Potential Purchase Price (the
"Purchase Price Differential") is set forth on Exhibit 2(c).

         During the six (6) years following the Closing, at the end of each six
(6) month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such
determination. In no event will the purchase price

<PAGE>   2





recalculation cause (x) Seller to return any portion of the purchase price
previously paid to Seller by AmSurg or (y) the aggregate consideration paid by
AmSurg to exceed the Potential Purchase Price.


ARTICLE 3.        CLOSING

         3.1.     CLOSING. The closing ("Closing") of the sale and purchase of
the Purchased Assets shall take place at the offices of Bass, Berry & Sims PLC,
First American Center, Nashville, Tennessee 37238, within 10 business days after
the satisfaction of all conditions to the parties' obligations to consummate the
transactions contemplated hereby, which shall in no event be later than August
31, 1998, or at such other time as shall be agreed upon by all the parties
hereto (the "Closing Date"). The Closing shall be effective as of August 4,

any agreement, indenture, instrument, lease, security agreement, mortgage or

<PAGE>   4





         4.5.     OWNERSHIP OF PURCHASED ASSETS. Westlake owns and possesses and
has good and marketable title to all of the Purchased Assets, free and clear of
all mortgages, pledges, liens, security interests, conditional sale agreements,
defects, charges, encumbrances and rights of third parties, and no conditions
exist which could give rise to any such mortgage, pledge, lien, security
interest, defect, charge, encumbrance on, or right of any such third party to,
the Purchased Assets.

         Schedule 4.5 contains an accurate and complete description of the
Purchased Assets, which include, but are not limited to, supplies, inventory,
uncollected accounts receivable and equipment owned by Westlake, and which are
all of the assets which are in any way necessary to the continued operation of
the Center as it is now being conducted. All of the Purchased Assets are in good
working condition and repair, normal wear and tear excepted, and are adequate
for the uses for which they are intended. Schedule 4.5 also sets forth the
current book value of all equipment included in the Purchased Assets.

undivided 57% interest in the Purchased Assets, including a 3% undivided
interest to Seller.

         4.6.     NO LIABILITIES OR ADVERSE CONDITIONS. Except as and to the
extent of the amounts specifically reflected in the Financial Information,
Westlake does not have any material liabilities or obligations of any nature
with respect to the Center, whether, absolute, accrued, contingent or otherwise
and whether due or to become due (including, without limitation, liabilities for
taxes and interest, penalties and other charges payable with respect thereto).

         Furthermore, Westlake does not know or have reason to know of any basis
for the assertion against Westlake of any such liability or obligation of any
nature not fully reflected in the Financial Information. There are no conditions
existing with respect to any of Westlake's facilities, properties, assets or
personnel, which might materially and adversely affect any of the Center's
properties, business or prospects.

         4.7.     ABSENCE OF CERTAIN CHANGES. Since December 31, 1997, with
respect to the Center, Westlake has not:

of conducting its business, other than changes in the ordinary course of

debt, contingency or other reserve;

         (d)      paid, discharged or satisfied any claim, lien, encumbrance or

since December 31, 1997 in the ordinary course of business consistent with past
practice;

         (e)      written off as uncollectible any notes or accounts receivable
or any portion thereof, except for immaterial write-offs made in the ordinary
course of business consistent with past practice;

         (f)      canceled any other debts or claims, or waived any rights, of

the Health Care Financing Administration ("HCFA") providing in part for a change
in the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).


         During the six (6) years following the Closing, at the end of each six
(6) month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such


<PAGE>   2

determination. In no event will the purchase price recalculation cause (x)
Seller to return any portion of the purchase price previously paid to Seller by
AmSurg or (y) the aggregate consideration paid by AmSurg to exceed the Potential
Purchase Price.

ASSET PURCHASE AGREEMENT


         THIS ASSET PURCHASE AGREEMENT (the "Agreement"), dated August 4, 1998,
is by and among AmSurg Westlake, Inc., a Tennessee corporation ("AmSurg"),
AmSurg Corp., a Tennessee corporation and the owner of all the outstanding
capital stock of AmSurg ("ASC"), Westlake Eye Surgery Center, a California
partnership ("Westlake"), and the individual set forth on the signature pages
attached hereto ("Seller").

         WHEREAS, AmSurg desires to purchase and Seller desires to sell certain
of Seller's assets, as more fully described herein, upon and subject to the
terms and conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties and covenants of the parties hereinafter set forth,
the parties agree as follows:

ARTICLE 1.        PURCHASE AND SALE OF ASSETS

         1.1.     PURCHASE AND SALE OF ASSETS. Subject to the terms and
conditions of this Agreement, at the Closing, Seller shall sell, transfer,
convey, assign and deliver to AmSurg and AmSurg shall purchase, acquire and
accept from Seller an undivided 10% interest in the assets comprising the
business operations of the ophthalmic ambulatory surgery center (the "Center")
owned and operated by Westlake and located in Westlake Village, California,
tangible or intangible, recorded or unrecorded, known or unknown, of whatsoever
type, kind, description, or nature owned, leased, held, possessed, vested in or
claimed in whole or in part by Seller on the Closing Date (the "Purchased
Assets"), which Purchased Assets shall specifically include the accounts
receivable of the Center, but which shall specifically exclude cash and the
account receivable from Westlake Laser Surgery Center in the approximate amount
of $47,656.

         1.2.     ASSUMPTION OF LIABILITIES. Except as described in Schedule
1.2, AmSurg will not assume any debts, liabilities, obligations, expenses,
taxes, contracts or commitments of Seller, Westlake or the Center of any kind,
character or description, whether accrued, absolute, contingent or otherwise
("Liabilities"), no matter whether arising before or after the Closing, and
whether or not reflected or reserved against in Seller's, Westlake's or the
Center's financial statements, books of account or records. Westlake and Seller
will indemnify AmSurg against and hold it harmless from any such Liabilities.
AmSurg will cause The Westlake Ophthalmology ASC, L.P., a Tennessee limited
partnership (the "Partnership"), to assume all Liabilities arising after the
effective date of the transaction which relate to supplies received by the
Center or services rendered to the Center after the effective date of the
transaction, regardless of the date such Liabilities arose.

ARTICLE 2.        PURCHASE PRICE

         The initial purchase price of the Purchased Assets (the "Initial
Purchase Price") shall be $341,978.00. The Initial Purchase Price shall be paid
(a) $297,521.00 in cash and (b) in 6698 shares of the Class A common stock of
ASC (the "AmSurg Common Stock").

         AmSurg and Seller acknowledge that the rule proposed in June 1998 by
the Health Care Financing Administration ("HCFA") providing in part for a change
in the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).

         During the six (6) years following the Closing, at the end of each six
(6) month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any

<PAGE>   2
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such
determination. In no event will the purchase price recalculation cause (x)
Seller to return any portion of the purchase price previously paid to Seller by
AmSurg or (y) the aggregate consideration paid by AmSurg to exceed the Potential
Purchase Price.

ARTICLE 3.        CLOSING

         3.1.     CLOSING. The closing ("Closing") of the sale and purchase of
the Purchased Assets shall take place at the offices of Bass, Berry & Sims PLC,
First American Center, Nashville, Tennessee 37238, within 10 business days after
the satisfaction of all conditions to the parties' obligations to consummate the
transactions contemplated hereby, which shall in no event be later than August
31, 1998, or at such other time as shall be agreed upon by all the parties
hereto (the "Closing Date"). The Closing shall be effective as of August 4,
1998.

         3.2.     OBLIGATIONS OF THE PARTIES AT THE CLOSING.

ARTICLE 4.        REPRESENTATIONS AND WARRANTIES BY WESTLAKE

         Westlake represents and warrants as follows:

         4.1.     ORGANIZATION. Westlake is a partnership organized under the

business as now conducted and to own, lease or operate its properties and assets
as now owned, leased or operated.

         4.2.     AUTHORIZATION. Westlake has full power and authority to enter
into this Agreement and perform its obligations hereunder and carry out the
transactions contemplated hereby. The execution, delivery and performance by
Westlake of this Agreement, the distribution by Westlake of the Purchased Assets
to Seller and the consummation of the transactions contemplated hereby,
including the conveyance, assignment, transfer and delivery of the Purchased
Assets, have been duly authorized and approved by all necessary partnership and
partner action, and this Agreement, when executed, will constitute a valid and
binding obligation of Westlake enforceable against Westlake in accordance with
its terms.

         4.3.     NO VIOLATION. The execution and delivery of this Agreement and
the distribution of the Purchased Assets to Seller by Westlake does not, and the
consummation of the transactions contemplated hereby will not, (a) violate any
provision of, or result in the creation of any lien or security interest under,
any agreement, indenture, instrument, lease, security agreement, mortgage or
lien to which Westlake is a party or by which any of Westlake's assets or
properties are bound which violation or lien would have a material adverse
effect on the business or operations of Westlake or the Center; (b) violate any
provision of the partnership agreement of Westlake; (c) violate any order,
arbitration award, judgment, writ, injunction, decree, statute, rule or
regulation applicable to Westlake which violation would have a material adverse
effect on the business or operations of Westlake or the Center; or (d) violate
any other contractual or legal obligation or restriction to which Westlake is
subject which violation would have a material adverse effect on the business or
operations of Westlake or the Center.

         4.4.     FINANCIAL INFORMATION. Westlake has delivered to AmSurg:
statements of Center charges and cash receipts by month for the years ended
December 31, 1996 and December 31, 1997 attached hereto as Schedule 4.4(a), cash
basis unaudited statements of income for the Center for the years ended December

unaudited balance sheets of the Center at December 31, 1997 and March 31, 1998
attached hereto as Schedule 4.4(c), and details of patient accounts receivable
for the Center at the Closing Date attached hereto as Schedule 4.4(d)
(hereinafter collectively referred to as "Financial Information"). The Financial
Information fairly presents the assets, liabilities, financial condition and
results of operation of the Center as at the respective dates thereof and for
the periods therein referred to, prepared on a cash basis and accurately
reflects the revenues and expenses of the Center for the periods covered thereby
and, in particular, reflects all expenses necessary for the efficient operation
of the Center as a stand-alone entity. The Financial Information reflects the
consistent application of such accounting principles throughout the periods
involved.

         4.5.     OWNERSHIP OF PURCHASED ASSETS. Westlake owns and possesses and
has good and marketable title to all of the Purchased Assets, free and clear of
all mortgages, pledges, liens, security interests, conditional sale agreements,
defects, charges, encumbrances and rights of third parties, and no conditions
exist which could give rise to any such mortgage, pledge, lien, security
interest, defect, charge, encumbrance on, or right of any such third party to,
the Purchased Assets.

         Schedule 4.5 contains an accurate and complete description of the
Purchased Assets, which include, but are not limited to, supplies, inventory,
uncollected accounts receivable and equipment owned by Westlake, and which are
all of the assets which are in any way necessary to the continued operation of
the Center as it is

now being conducted. All of the Purchased Assets are in good working condition
and repair, normal wear and tear excepted, and are adequate for the uses for
which they are intended. Schedule 4.5 also sets forth the current book value of
all equipment included in the Purchased Assets.

undivided 57% interest in the Purchased Assets, including a 10% undivided
interest to Seller.

         4.6.     NO LIABILITIES OR ADVERSE CONDITIONS. Except as and to the
extent of the amounts specifically reflected in the Financial Information,
Westlake does not have any material liabilities or obligations of any nature
with respect to the Center, whether, absolute, accrued, contingent or otherwise
and whether due or to become due (including, without limitation, liabilities for
taxes and interest, penalties and other charges payable with respect thereto).

         Furthermore, Westlake does not know or have reason to know of any basis
for the assertion against Westlake of any such liability or obligation of any
nature not fully reflected in the Financial Information. There are no conditions
existing with respect to any of Westlake's facilities, properties, assets or
personnel, which might materially and adversely affect any of the Center's
properties, business or prospects.

respect to the Center, Westlake has not:

of conducting its business, other than changes in the ordinary course of
business;

         (c)      incurred any obligations or liabilities (whether absolute,
accrued, contingent or otherwise and whether due or to become due), except items
incurred in the ordinary course of business and consistent with past practice,
or experienced any change in any assumptions or methods of calculating any bad

         (d)      paid, discharged or satisfied any claim, lien, encumbrance or

which were paid, discharged or satisfied since the date thereof in the ordinary
course of business consistent with past practice, or

                  (ii)     which were incurred and paid, discharged or satisfied
since December 31, 1997 in the ordinary course of business consistent with past
practice;

         (e)      written off as uncollectible any notes or accounts receivable
or any portion thereof, except for immaterial write-offs made in the ordinary

substantial value;

         (g)      sold, transferred or conveyed any of its properties or assets,

respect to such Losses shall be made by Westlake and Seller only to the extent
of such excess over the Basket.

transaction, regardless of the date such Liabilities arose.

ARTICLE 2.        PURCHASE PRICE

         The initial purchase price of the Purchased Assets (the "Initial
Purchase Price") shall be $341,978.00. The Initial Purchase Price shall be paid
(a) $297,521.00 in cash and (b) in 6698 shares of the Class A common stock of
ASC (the "AmSurg Common Stock").

         AmSurg and Seller acknowledge that the rule proposed in June 1998 by
the Health Care Financing Administration ("HCFA") providing in part for a change
in the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).

         During the six (6) years following the Closing, at the end of each six
(6) month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any

<PAGE>   2
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such
determination. In no event will the purchase price recalculation cause (x)
Seller to return any portion of the purchase price previously paid to Seller by
AmSurg or (y) the aggregate consideration paid by AmSurg to exceed the Potential
Purchase Price.

ARTICLE 3.        CLOSING

         3.1.     CLOSING. The closing ("Closing") of the sale and purchase of

         (b)      Any other Loss incidental to the foregoing.

         12.3.    PROCEDURE.

         (a)      The indemnified party shall promptly notify the indemnifying
party of any claim, demand, action or proceeding for which indemnification will
be sought under Sections 12.1 or 12.2 of this Agreement, and, if such claim,
demand, action or proceeding is a third party claim, demand, action or
proceeding, the indemnifying party will have the right at its expense to assume
the defense thereof using counsel reasonably acceptable to the indemnified
party. The indemnified party shall have the right to participate, at its own
expense, with respect to any such third party claim, demand, action or
proceeding. In connection with any such third party claim, demand, action or
proceeding, AmSurg, ASC, Westlake and Seller shall cooperate with each other and
provide each other with access to relevant books and records in their
possession. No such third party claim, demand, action or proceeding shall be
settled without the prior written consent of the indemnified party. If a firm
written offer is made to settle any such third party claim, demand, action or
proceeding and the indemnifying party proposes to accept such settlement and the
indemnified party refuses to consent to such settlement, then: (i) the
indemnifying party shall be excused from, and the indemnified party shall be
solely responsible for, all further defense of such third party claim, demand,
action or proceeding; and (ii) the maximum liability of the indemnifying party
relating to such third party claim, demand, action or proceeding shall be the
amount of the proposed settlement if the amount thereafter recovered from the
indemnified party on such third party claim, demand, action or proceeding is
greater than the amount of the proposed settlement.

         (b)      Any claim of indemnity of AmSurg or ASC against Westlake with
respect to Section 12.1 hereof may in AmSurg's discretion be discharged by
setoff against any amounts owed or owing to Westlake under the Agreement of
Limited Partnership between Westlake and AmSurg.

         (c)      Notwithstanding the foregoing, Seller shall not be required to
indemnify AmSurg or ASC for any amount in excess of the Purchase Price.

         (d)      Notwithstanding the foregoing, Westlake and Seller shall not
be obligated to make any indemnification under Section 12.1 unless the aggregate
amount of Losses exceeds $10,000 (the "Basket"), and such indemnification with
respect to such Losses shall be made by Westlake and Seller only to the extent
of such excess over the Basket.

ARTICLE 13.       SURVIVAL OF REPRESENTATIONS AND WARRANTIES

         13.1.    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties contained herein shall survive the Closing Date
and any investigation made by or on behalf of any party hereto, and shall

described in Section 12.1(b), which shall survive for the applicable statute of
limitations, including any waivers thereof, Section 12.1(c), which shall not
terminate, and any breach of the representations and warranties contained in
Sections 4.6 and 4.9 with respect to professional malpractice claims arising
before the Closing Date, which shall not terminate).

         In addition, in the event that all of the Partnership, AmSurg, ASC, or
their successors or assigns, dissolves, liquidates or otherwise ceases to exist,
the provisions of Section 5.16 hereof shall terminate and be of no further force
or effect.

         13.2.    REMEDIES CUMULATIVE. The remedies provided herein shall be
cumulative and shall not preclude the assertion by any party hereto of any other
rights or the seeking of any other remedies against the other party hereto.

         (a)      by mutual agreement of Seller and AmSurg;

         (b)      by AmSurg, if there has been a material violation or breach by
Westlake or Seller of any of the agreements, representations or warranties
contained in this Agreement which has not been waived in writing, or if any of
the conditions set forth in Article 10 hereof have not been satisfied by the
Closing or have not been waived in writing by AmSurg;

         (c)      by Seller, if there has been a material violation or breach by

         (e)      By either AmSurg or Seller if the other makes an assignment
for the benefit of creditors, files a voluntary petition in bankruptcy or seeks
or consents to any reorganization or similar relief under any present or future

ASSET PURCHASE AGREEMENT
- --------------------------------------------------------------------------------

      THIS ASSET PURCHASE AGREEMENT (the "Agreement"), dated August 4, 1998, is
by and among AmSurg Westlake, Inc., a Tennessee corporation ("AmSurg"), AmSurg
Corp., a Tennessee corporation and the owner of all the outstanding capital
stock of AmSurg ("ASC"), Westlake Eye Surgery Center, a California partnership
("Westlake"), and the individual set forth on the signature pages attached
hereto ("Seller").

      WHEREAS, AmSurg desires to purchase and Seller desires to sell certain of
Seller's assets, as more fully described herein, upon and subject to the terms
and conditions contained in this Agreement.

      NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties and covenants of the parties hereinafter set forth,
the parties agree as follows:

ARTICLE 1.    PURCHASE AND SALE OF ASSETS

      1.1.    PURCHASE AND SALE OF ASSETS. Subject to the terms and conditions
of this Agreement, at the Closing, Seller shall sell, transfer, convey, assign
and deliver to AmSurg and AmSurg shall purchase, acquire and accept from Seller
an undivided 8 1/2% interest in the assets comprising the business operations of
the ophthalmic ambulatory surgery center (the "Center") owned and operated by
Westlake and located in Westlake Village, California, tangible or intangible,
recorded or unrecorded, known or unknown, of whatsoever type, kind, description,
or nature owned, leased, held, possessed, vested in or claimed in whole or in
part by Seller on the Closing Date (the "Purchased Assets"), which Purchased
Assets shall specifically include the accounts receivable of the Center, but
which shall specifically exclude cash and the account receivable from Westlake
Laser Surgery Center in the approximate amount of $47,656.

      1.2.    ASSUMPTION OF LIABILITIES. Except as described in Schedule 1.2,
AmSurg will not assume any debts, liabilities, obligations, expenses, taxes,
contracts or commitments of Seller, Westlake or the Center of any kind,
character or description, whether accrued, absolute, contingent or otherwise
("Liabilities"), no matter whether arising before or after the Closing, and
whether or not reflected or reserved against in Seller's, Westlake's or the
Center's financial statements, books of account or records. Westlake and Seller
will indemnify AmSurg against and hold it harmless from any such Liabilities.
AmSurg will cause The Westlake Ophthalmology ASC, L.P., a Tennessee limited
partnership (the "Partnership"), to assume all Liabilities arising after the
effective date of the transaction which relate to supplies received by the
Center or services rendered to the Center after the effective date of the
transaction, regardless of the date such Liabilities arose.

ARTICLE 2.    PURCHASE PRICE

      The initial purchase price of the Purchased Assets (the "Initial Purchase
Price") shall be $290,682.00. The Initial Purchase Price shall be paid (a)
$261,614.00 in cash and (b) in 4379 shares of the Class A common stock of ASC
(the "AmSurg Common Stock").

      AmSurg and Seller acknowledge that the rule proposed in June 1998 by the
Health Care Financing Administration ("HCFA") providing in part for a change in
the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).

      During the six (6) years following the Closing, at the end of each six (6)
month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional


<PAGE>   2

consideration within sixty (60) days after such determination. In no event will
the purchase price recalculation cause (x) Seller to return any portion of the
purchase price previously paid to Seller by AmSurg or (y) the aggregate
consideration paid by AmSurg to exceed the Potential Purchase Price.

ARTICLE 3.    CLOSING

      3.1.    CLOSING. The closing ("Closing") of the sale and purchase of the
Purchased Assets shall take place at the offices of Bass, Berry & Sims PLC,
First American Center, Nashville, Tennessee 37238, within 10 business days after
the satisfaction of all conditions to the parties' obligations to consummate the
transactions contemplated hereby, which shall in no event be later than August
31, 1998, or at such other time as shall be agreed upon by all the parties
hereto (the "Closing Date"). The Closing shall be effective as of August 4,
1998.

      3.2.    OBLIGATIONS OF THE PARTIES AT THE CLOSING.

              (iv)     such deeds, bills of sale, endorsements, assignments and
other good and sufficient instruments of conveyance and transfer, in form and
substance reasonably satisfactory to AmSurg, as shall be effective to vest in

ARTICLE 4.    REPRESENTATIONS AND WARRANTIES BY WESTLAKE

      Westlake represents and warrants as follows:

      4.1.    ORGANIZATION. Westlake is a partnership organized under the laws
of the State of California with full power and authority to conduct its business
as now conducted and to own, lease or operate its properties and assets as now
owned, leased or operated.

      4.2.    AUTHORIZATION. Westlake has full power and authority to enter into
this Agreement and perform its obligations hereunder and carry out the
transactions contemplated hereby. The execution, delivery and performance by
Westlake of this Agreement, the distribution by Westlake of the Purchased Assets
to Seller and the consummation of the transactions contemplated hereby,
including the conveyance, assignment, transfer and delivery of the Purchased
Assets, have been duly authorized and approved by all necessary partnership and
partner action, and this Agreement, when executed, will constitute a valid and
binding obligation of Westlake enforceable against Westlake in accordance with
its terms.

      4.3.    NO VIOLATION. The execution and delivery of this Agreement and the
distribution of the Purchased Assets to Seller by Westlake does not, and the
consummation of the transactions contemplated hereby will not, (a) violate any
provision of, or result in the creation of any lien or security interest under,
any agreement, indenture, instrument, lease, security agreement, mortgage or
lien to which Westlake is a party or by which any of Westlake's assets or
properties are bound which violation or lien would have a material adverse
effect on the business or operations of Westlake or the Center; (b) violate any
provision of the partnership agreement of Westlake; (c) violate any order,
arbitration award, judgment, writ, injunction, decree, statute, rule or
regulation applicable to Westlake which violation would have a material adverse
effect on the business or operations of Westlake or the Center; or (d) violate
any other contractual or legal obligation or restriction to which Westlake is
subject which violation would have a material adverse effect on the business or
operations of Westlake or the Center.

      4.4.    FINANCIAL INFORMATION. Westlake has delivered to AmSurg:
statements of Center charges and cash receipts by month for the years ended
December 31, 1996 and December 31, 1997 attached hereto as Schedule 4.4(a), cash
basis unaudited statements of income for the Center for the years ended December

attached hereto as Schedule 4.4(c), and details of patient accounts receivable
for the Center at the Closing Date attached hereto as Schedule 4.4(d)
(hereinafter collectively referred to as "Financial Information"). The Financial
Information fairly presents the assets, liabilities, financial condition and
results of operation of the Center as at the respective dates thereof and for
the periods therein referred to, prepared on a cash basis and accurately
reflects the revenues and expenses of the Center for the periods covered thereby
and, in particular, reflects all expenses necessary for the efficient operation
of the Center as a stand-alone entity. The Financial Information reflects the
consistent application of such accounting principles throughout the periods
involved.

      4.5.    OWNERSHIP OF PURCHASED ASSETS. Westlake owns and possesses and has
good and marketable title to all of the Purchased Assets, free and clear of all
mortgages, pledges, liens, security interests, conditional sale agreements,
defects, charges, encumbrances and rights of third parties, and no conditions
exist which could give rise to any such mortgage, pledge, lien, security
interest, defect, charge, encumbrance on, or right of any such third party to,
the Purchased Assets.

      Schedule 4.5 contains an accurate and complete description of the
Purchased Assets, which include, but are not limited to, supplies, inventory,
uncollected accounts receivable and equipment owned by Westlake, and which are
all of the assets which are in any way necessary to the continued operation of
the Center as it is

- --------------------------------------------------------------------------------

now being conducted. All of the Purchased Assets are in good working condition
and repair, normal wear and tear excepted, and are adequate for the uses for
which they are intended. Schedule 4.5 also sets forth the current book value of
all equipment included in the Purchased Assets.

interest to Seller.

      4.6.    NO LIABILITIES OR ADVERSE CONDITIONS. Except as and to the extent
of the amounts specifically reflected in the Financial Information, Westlake
does not have any material liabilities or obligations of any nature with respect
to the Center, whether, absolute, accrued, contingent or otherwise and whether
due or to become due (including, without limitation, liabilities for taxes and
interest, penalties and other charges payable with respect thereto).

      Furthermore, Westlake does not know or have reason to know of any basis
for the assertion against Westlake of any such liability or obligation of any
nature not fully reflected in the Financial Information. There are no conditions
existing with respect to any of Westlake's facilities, properties, assets or
personnel, which might materially and adversely affect any of the Center's
properties, business or prospects.

      4.7.    ABSENCE OF CERTAIN CHANGES. Since December 31, 1997, with respect 
to the Center, Westlake has not:

financial condition, assets, liabilities, business or prospects, or suffered any

conducting its business, other than changes in the ordinary course of business;

      (c)     incurred any obligations or liabilities (whether absolute,
accrued, contingent or otherwise and whether due or to become due), except items
incurred in the ordinary course of business and consistent with past practice,

      (c)     Notwithstanding the foregoing, Seller shall not be required to
indemnify AmSurg or ASC for any amount in excess of the Purchase Price.

      (d)     Notwithstanding the foregoing, Westlake and Seller shall not be
obligated to make any indemnification under Section 12.1 unless the aggregate
amount of Losses exceeds $10,000 (the "Basket"), and such indemnification with
respect to such Losses shall be made by Westlake and Seller only to the extent
of such excess over the Basket.

ASSET PURCHASE AGREEMENT
- --------------------------------------------------------------------------------

      THIS ASSET PURCHASE AGREEMENT (the "Agreement"), dated August 4, 1998, is
by and among AmSurg Westlake, Inc., a Tennessee corporation ("AmSurg"), AmSurg
Corp., a Tennessee corporation and the owner of all the outstanding capital
stock of AmSurg ("ASC"), Westlake Eye Surgery Center, a California partnership
("Westlake"), and the individual set forth on the signature pages attached
hereto ("Seller").

      WHEREAS, AmSurg desires to purchase and Seller desires to sell certain of
Seller's assets, as more fully described herein, upon and subject to the terms
and conditions contained in this Agreement.

      NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties and covenants of the parties hereinafter set forth,
the parties agree as follows:

ARTICLE 1.    PURCHASE AND SALE OF ASSETS

      1.1.    PURCHASE AND SALE OF ASSETS. Subject to the terms and conditions
of this Agreement, at the Closing, Seller shall sell, transfer, convey, assign
and deliver to AmSurg and AmSurg shall purchase, acquire and accept from Seller
an undivided 11 1/4% interest in the assets comprising the business operations
of the ophthalmic ambulatory surgery center (the "Center") owned and operated by
Westlake and located in Westlake Village, California, tangible or intangible,
recorded or unrecorded, known or unknown, of whatsoever type, kind, description,
or nature owned, leased, held, possessed, vested in or claimed in whole or in
part by Seller on the Closing Date (the "Purchased Assets"), which Purchased
Assets shall specifically include the accounts receivable of the Center, but
which shall specifically exclude cash and the account receivable from Westlake
Laser Surgery Center in the approximate amount of $47,656.

      1.2.    ASSUMPTION OF LIABILITIES. Except as described in Schedule 1.2,
AmSurg will not assume any debts, liabilities, obligations, expenses, taxes,
contracts or commitments of Seller, Westlake or the Center of any kind,
character or description, whether accrued, absolute, contingent or otherwise
("Liabilities"), no matter whether arising before or after the Closing, and
whether or not reflected or reserved against in Seller's, Westlake's or the
Center's financial statements, books of account or records. Westlake and Seller
will indemnify AmSurg against and hold it harmless from any such Liabilities.
AmSurg will cause The Westlake Ophthalmology ASC, L.P., a Tennessee limited
partnership (the "Partnership"), to assume all Liabilities arising after the
effective date of the transaction which relate to supplies received by the
Center or services rendered to the Center after the effective date of the
transaction, regardless of the date such Liabilities arose.

ARTICLE 2.    PURCHASE PRICE

      The initial purchase price of the Purchased Assets (the "Initial Purchase
Price") shall be $384,726.00. The Initial Purchase Price shall be paid (a)
$346,253.00 in cash and (b) in 5796 shares of the Class A common stock of ASC
(the "AmSurg Common Stock").

      AmSurg and Seller acknowledge that the rule proposed in June 1998 by the
Health Care Financing Administration ("HCFA") providing in part for a change in
the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).

      During the six (6) years following the Closing, at the end of each six (6)
month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any

Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such
determination. In no event will the purchase price recalculation cause (x)
Seller to return any portion of the purchase price previously paid to Seller by
AmSurg or (y) the aggregate consideration paid by AmSurg to exceed the Potential
Purchase Price.

agrees that AmSurg, in addition to all other remedies it may have, shall have
the right to injunctive relief if there is such a breach.

ASSET PURCHASE AGREEMENT
- --------------------------------------------------------------------------------


         THIS ASSET PURCHASE AGREEMENT (the "Agreement"), dated August 4, 1998,
is by and among AmSurg Westlake, Inc., a Tennessee corporation ("AmSurg"),
Westlake Eye Surgery Center, a California partnership ("Westlake"), and the
individual set forth on the signature pages attached hereto ("Seller").

         WHEREAS, AmSurg desires to purchase and Seller desires to sell certain
of Seller's assets, as more fully described herein, upon and subject to the
terms and conditions contained in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties and covenants of the parties hereinafter set forth,
the parties agree as follows:

ARTICLE 1.    PURCHASE AND SALE OF ASSETS

      1.1.    PURCHASE AND SALE OF ASSETS. Subject to the terms and conditions
of this Agreement, at the Closing, Seller shall sell, transfer, convey, assign
and deliver to AmSurg and AmSurg shall purchase, acquire and accept from Seller
an undivided 11 1/4% interest in the assets comprising the business operations
of the ophthalmic ambulatory surgery center (the "Center") owned and operated by
Westlake and located in Westlake Village, California, tangible or intangible,
recorded or unrecorded, known or unknown, of whatsoever type, kind, description,
or nature owned, leased, held, possessed, vested in or claimed in whole or in
part by Seller on the Closing Date (the "Purchased Assets"), which Purchased
Assets shall specifically include the accounts receivable of the Center, but
which shall specifically exclude cash and the account receivable from Westlake
Laser Surgery Center in the approximate amount of $47,656.

      1.2.    ASSUMPTION OF LIABILITIES. Except as described Schedule 1.2,
AmSurg will not assume any debts, liabilities, obligations, expenses, taxes,
contracts or commitments of Seller, Westlake or the Center of any kind,
character or description, whether accrued, absolute, contingent or otherwise
("Liabilities"), no matter whether arising before or after the Closing, and
whether or not reflected or reserved against in Seller's, Westlake's or the
Center's financial statements, books of account or records. Westlake and Seller
will indemnify AmSurg against and hold it harmless from any such Liabilities.
AmSurg will cause The Westlake Ophthalmology ASC, L.P., a Tennessee limited
partnership (the "Partnership"), to assume all Liabilities arising after the
effective date of the transaction which relate to supplies received by the
Center or services rendered to the Center after the effective date of the
transaction, regardless of the date such Liabilities arose.

ARTICLE 2.    PURCHASE PRICE

      The initial purchase price of the Purchased Assets (the "Initial Purchase
Price") shall be $384,726.00 in cash.

      AmSurg and Seller acknowledge that the rule proposed in June 1998 by the
Health Care Financing Administration ("HCFA") providing in part for a change in
the payment methodology and payment rates utilized by HCFA to reimburse
ambulatory surgery centers as it may be adopted or amended (the "Proposed
Rule"), could have a negative effect on the future revenues and earnings of the
Center. In order to address the uncertainty regarding the Proposed Rule and its
effect on the Center, the Initial Purchase Price has been calculated based on
the financial statements for the Center for the calendar year 1997 and the
annualized procedure volume for Medicare cases performed in the Center from
January 1, 1998 through May 31, 1998, as set forth in Exhibit 2(a). Exhibit 2(b)
sets forth what the purchase price would have been without any adjustment for
the proposed Medicare reimbursement rate changes (the "Potential Purchase
Price"). The difference between the Initial Purchase Price and the Potential
Purchase Price (the "Purchase Price Differential") is set forth on Exhibit 2(c).

      During the six (6) years following the Closing, at the end of each six (6)
month period, if a final version of the Proposed Rule has not been adopted
during such period, then AmSurg will pay as additional consideration
("Additional Purchase Price") an amount in cash equal to one twelfth (1/12) of
the Purchase Price Differential as set forth on Exhibit 2(c), together with
interest thereon at the rate equal to the prime rate as published from time to
time by SunTrust Bank in Nashville, Tennessee, accruing from the Closing Date.
In the event that a final version of the Proposed Rule is adopted during the six
(6) years following the Closing, then the purchase price will be recalculated
and adjusted utilizing the formula set forth on Exhibit 2(a) and substituting
the final Medicare reimbursement rates for the proposed Medicare reimbursement
rates set forth therein (the "Adjusted Purchase Price"). If the Adjusted
Purchase Price exceeds the sum of (a) the Initial Purchase Price and (b) any
Additional Purchase Price previously paid by AmSurg, AmSurg will pay in cash
such amount as additional consideration within sixty (60) days after such
determination. In no event will the purchase price recalculation cause (x)
Seller to return any portion of the purchase price previously paid to Seller by
AmSurg or (y)

<PAGE>   2

the aggregate consideration paid by AmSurg to exceed the Potential Purchase
Price.

ARTICLE 3.    CLOSING

      3.1.    CLOSING. The closing ("Closing") of the sale and purchase of the
Purchased Assets shall take place at the offices of Bass, Berry & Sims PLC,
First American Center, Nashville, Tennessee 37238, within 10 business days after
the satisfaction of all conditions to the parties' obligations to consummate the
transactions contemplated hereby, which shall in no event be later than August

hereto (the "Closing Date"). The Closing shall be effective as of August 4,

consummation of the transactions contemplated hereby will not, (a) violate any
provision of, or result in the creation of any lien or security interest under,
any agreement, indenture, instrument, lease, security agreement, mortgage or
lien to which Westlake is a party or by which any of Westlake's assets or
properties are bound which violation or lien would have a material adverse
effect on the business or operations of Westlake or the Center; (b) violate any
provision of the partnership agreement of Westlake; (c) violate any order,
arbitration award, judgment, writ, injunction, decree, statute, rule or

operations of Westlake or the Center.

      4.4.    FINANCIAL INFORMATION. Westlake has delivered to AmSurg:

(hereinafter collectively referred to as "Financial Information"). The Financial
Information fairly presents the assets, liabilities, financial condition and

good and marketable title to all of the Purchased Assets, free and clear of all

<PAGE>   4

encumbrance on, or right of any such third party to, the Purchased Assets.

      Schedule 4.5 contains an accurate and complete description of the
Purchased Assets, which include, but are not limited to, supplies, inventory,
uncollected accounts receivable and equipment owned by Westlake, and which are
all of the assets which are in any way necessary to the continued operation of

due or to become due (including, without limitation, liabilities for taxes and
interest, penalties and other charges payable with respect thereto).

business or operations of the Center. Schedule 4.9 sets forth a true and
accurate description of all claims, actions, investigations or proceedings
relating to the Center and its operations initiated since January 1, 1995.

      4.10.   COMPLIANCE WITH LAWS AND OTHER REGULATIONS. Westlake is in

      (a)     The indemnified party shall promptly notify the indemnifying party

sought under Sections 11.1 or 11.2 of this Agreement, and, if such claim,
demand, action or proceeding is a third party claim, demand, action or
proceeding, the indemnifying party will have the right at its expense to assume
the defense thereof using counsel reasonably acceptable to the indemnified
party. The indemnified party shall have the right to participate, at its own
expense, with respect to any such third party claim, demand, action or
proceeding. In connection with any such third party claim, demand, action or

settled without the prior written consent of the indemnified party. If a firm
written offer is made to settle any such third party claim, demand, action or

indemnifying party shall be excused from, and the indemnified party shall be
solely responsible for, all further defense of such third party claim, demand,
action or proceeding; and (ii) the maximum liability of the indemnifying party
relating to such third party claim, demand, action or proceeding shall be the
amount of the proposed settlement if the amount thereafter recovered from the
indemnified party on such third party claim, demand, action or proceeding is
greater than the amount of the proposed settlement.

      (b)     Any claim of indemnity of AmSurg against Westlake with respect to
Section 11.1 hereof may in AmSurg's discretion be discharged by setoff against
any amounts owed or owing to Westlake under the Agreement of Limited Partnership
between Westlake and
AmSurg.

      (c)     Notwithstanding the foregoing, Seller shall not be required to
indemnify AmSurg for any amount in excess of the Purchase Price.

      (d)     Notwithstanding the foregoing, Westlake and Seller shall not be
obligated to make any indemnification under Section 11.1 unless the aggregate
amount of Losses exceeds $10,000 (the "Basket"), and such indemnification with
respect to such Losses shall be made by Westlake and Seller only to the extent
of such excess over the Basket.

provisions of Section 5.16 hereof shall terminate and be of no further force or
effect.
