         Section 1.24     Contracts and Commitments.

                 (1)      Schedule 5.14 contains a true, accurate and complete
list, and Seller has delivered to APPM true and complete copies, of each
contract, agreement and other instrument (other than insurance contracts
identified in Schedule 5.24 or Lease Agreements identified in Schedule 5.20) to
which Seller is a party or by which it or any of its properties or assets are
bound including, without limitation, (i) all agreements between Seller, on the
one hand, and any government entity, Payor, provider, hospital, health
maintenance organization, other managed care organization or other third-party
provider, on the other hand, relating to the provision of medical, diagnostic
imaging or consulting services, treatments, patient referrals or other similar
activities; (ii) all indentures, mortgages, notes, loan or credit agreements
and other agreements and obligations relating to the borrowing of money or to
the direct or indirect guarantee or assumption of obligations of third parties
requiring Seller to make, or setting forth conditions under which Seller would
be required to make, aggregate future payments in excess of $10,000 in any
fiscal year or $25,000 in the aggregate; (iii) all agreements for capital
improvements or acquisitions involving an amount of $75,000 in any fiscal year
or $75,000 in the aggregate; (iv) all agreements containing a covenant limiting
the freedom of Seller (or any Physician Employee of Seller) to compete in any
line of business with any person or entity or in any geographic area; or (v)
all written contracts and commitments to which aggregate future payments by
Seller are in excess of $10,000 in any fiscal year or $25,000 in the aggregate
and that are not cancelable by providing notice of sixty (60) days or less.
Except as noted in Schedule 5.14, all such contracts, agreements or other
instruments are in full force and effect, there has been no threatened
cancellation thereof, there are no outstanding disputes thereunder, each is
with unrelated third parties and was entered into on an arms-length basis in
the ordinary course of business and, assuming the receipt of the appropriate
consents, each constituting an Assumed Contract will continue to be binding in
accordance with their terms after consummation of the transaction contemplated
herein.  Except as noted in Schedule 5.14, there are no contracts, agreements
or other instruments to which Seller is a party or is bound (other than
physician employment contracts and insurance policies) which could either
singularly or in the aggregate have a Material Adverse Effect on the value to
Buyer of the Purchased Assets, or which could inhibit or prevent Seller from
transferring to or vesting in Buyer good and sufficient title to the Purchased
Assets.  For each of the Assumed Liabilities, in every instance where consent
is necessary, Seller obtained and delivered to Buyer in writing, effective as
of the date hereof, such consents as are necessary to effect a valid and
binding transfer or assignment so as to enable Buyer to enjoy all of the rights
now enjoyed by Seller under such contracts.  Notwithstanding the foregoing,
Seller shall not transfer to Buyer any contracts or agreements relating to the
provision of professional medical services or other such agreements and
contracts that Buyer consents to in writing to be retained by Seller.  Except
as set forth in Schedule 5.14, no contract with a health care provider or Payor
has been materially amended or terminated within the last twelve (12) months.

                 (2)      Except as disclosed in Schedule 5.14, (i) Seller has
not received notice of any plan or intention of any other party to exercise any
right to cancel or terminate such contract, agreement or instrument, and Seller
is not aware of any fact(s) that would justify the exercise of such a right;
and (ii) Seller does not currently contemplate, or have reason to believe any
other Person currently contemplates, any amendment or change to any such
contract, agreement or instrument.

         Section 1.25     No Brokers.  Seller has not entered into and will not
enter into any agreement, arrangement or understanding with any person or firm
which will result in the obligation of Buyer to pay any finder's fee, brokerage
commission or similar payment.

         Section 1.26     No Other Agreements to Sell the Assets of the
Business.  Seller does not have any legal obligation, absolute or contingent,
to any Person to sell any of the Purchased Assets (other than agreements for
the sale of Inventory in the ordinary course), or to effect any sale of the
Business or to enter into any agreement with respect thereto.

         Section 1.27     Employee Matters.

                 (1)      Employment Contracts.  Except as set forth in
Schedule 5.17(a), Seller is not currently a party to any employment contract
(except for oral employment agreements which are terminable at will),

1974, as amended, and all rules and regulations from time to time promulgated
thereunder ("ERISA")), profit sharing, bonus, stock option, stock purchase or
other nonqualified benefit or compensation commitments, benefit plans,
arrangements or plans (whether written or oral), including all welfare plans
(as defined in Section 3(1) of ERISA) of or pertaining to Seller and any of its
present or former employees, or any predecessors in interest.

                 (2)      Employees.  As of February 28, 1998, Seller employed
a collective total of eight (8) full-time and part-time employees.  Schedule
5.17(b) lists each employee of, or consultant to, Seller who received combined
salary, benefits and bonuses for 1997 in excess of $50,000 or who is expected
to receive combined salary, benefits and bonuses in 1998 in excess of $50,000.
Seller is not delinquent in payment to any of its employees or Physician
Employees for wages, salaries, bonuses or other direct compensation for any
services performed for it to the date hereof or amounts required to be
reimbursed to such employees.

                 (3)      Severance Arrangements.  Except as set forth on
Schedule 5.17(c), upon termination of employment of any employee or Physician
Employee, no severance or other payments will become due and Seller has no
policy, past practice or plan of paying severance on termination of employment.

         Section 1.28     Labor Relations.

                 (1)      Except as set forth on Schedule 5.18(a), to the

plans to terminate employment with Seller, except by reason of terminating such
relationship by becoming an employee of Buyer in connection with Buyer's
purchase of the Business pursuant hereto.

                 (2)      Except as set forth in Schedule 5.18(b), there is no
unfair labor practice, charge or complaint or any other employment-related
matter against or involving Seller pending or threatened before the National
Labor Relations Board or any federal, state or local agency, authority or
court.

                 (3)      Except as set forth in Schedule 5.18(c), there are no
charges, investigations, administrative proceedings or formal complaints of
discrimination (including discrimination based upon sex, age, marital status,
race, national origin, the making of workers' compensation claims, sexual
preference, handicap or veteran status) pending or threatened before the Equal
Employment Opportunity Commission or any federal, state or local agency,
authority or court against Seller.  There have been no governmental audits of
the equal employment opportunity practices of Seller and no basis for any such
audit exists which, if conducted would result in a Material Adverse Effect on
Seller.

                 (4)      Except as set forth in Schedule 5.18(d), there are no
inquiries, investigations or monitoring activities of any licensed, registered,
or certified professional personnel employed or retained by, credentialed or
privileged, or otherwise affiliated with Seller pending or threatened by any
state professional board or agency charged with regulating the professional
activities of health care practitioners.

                 (1)      Identification.  Schedule 5.19(a) contains a complete
and accurate list of all employee benefit plans (within the meaning of Section
3(3) of ERISA) sponsored by Seller or to which Seller contributes on behalf of
its employees and all employee benefit plans previously sponsored or
contributed to on behalf of its employees within the three years preceding the
date hereof (the "Employee Benefit Plans").  Seller has provided to Buyer
copies of all plan documents (as they may have been amended to the date
hereof), determination letters, pending determination letter applications,
trust instruments, insurance contracts or policies related to an Employee
Benefit Plan, administrative services contracts, annual reports, actuarial
valuations, summary plan descriptions, summaries of material modifications,
administrative forms and other documents that constitute a part of or are
incident to the administration of the Employee Benefit Plans.  In addition,
Seller has provided or made available to Buyer a written description of all
existing practices engaged in by Seller that constitute Employee Benefit Plans.
Except as set forth in Schedule 5.19(a), subject to the requirements of ERISA,
each of the Employee Benefit Plans can be terminated or amended at will by
Seller without any further liability or obligation on the part of such entity
to make further contributions or payments in connection therewith following
such termination.  Except as set forth in Schedule 5.19(a), no unwritten
amendment exists with respect to any Employee Benefit Plan.

                 (2)      Administration.  Each Employee Benefit Plan has been
administered and maintained in compliance with all applicable laws, rules and
regulations, except where the failure to be in compliance would not,
individually or in the aggregate, result in a Material Adverse Effect to
Seller.

                 (3)      Examinations.  Except as set forth in Schedule
5.19(c), Seller has not received any notice that any Employee Benefit Plan is
currently the subject of an audit, investigation, enforcement action or other
similar proceeding conducted by any state or federal agency or authority.

                 (4)      Prohibited Transactions.  No prohibited transactions
(within the meaning of Section 4975 of the Code or Section 406 of ERISA) have
occurred with respect to any Employee Benefit Plan.  There has been no breach
of any duty under ERISA or applicable law (including, without limitation, any
health care contractor requirements or any other tax law requirements, or
conditions to favorable tax treatment, applicable to such plan), which could
result, directly or indirectly, (including through any obligation of
indemnification or contribution), in any taxes, penalties or other liability to
Seller, APPM or any of their respective Affiliates.

                 (5)      Claims and Litigation.  Except as set forth in
Schedule 5.19(e), no pending or threatened claims, suits or other proceedings
exist with respect to any Employee Benefit Plan other than normal benefit
claims filed by participants or beneficiaries.

                 (6)      Qualification.  Seller has received a favorable
determination letter or ruling from the IRS for each of the Employee Benefit
Plans intended to be qualified within the meaning of Section 401(a) or
501(c)(9) of the Code and/or tax-exempt within the meaning of Section 501(a) of
the Code and, to the best knowledge of Seller and each Principal Stockholder,
has been continually qualified under the applicable section of the Code since
the effective date of such Employee Benefit Plan.  No proceedings exist or have
been threatened that could result in the revocation of any such favorable
determination letter or ruling.

                 (7)      Funding Status.  Except as set forth in Schedule
5.19(g), no accumulated funding deficiency (within the meaning of Section 412
of the Code), whether waived or unwaived, exists with respect to any Employee
Benefit Plan or any plan sponsored by any member of a controlled group (within
the meaning of Section 412(n)(6)(B) of the Code) in which Seller is a member (a
"Controlled Group").  Except as set forth in Schedule 5.19(g), with respect to
each Employee Benefit Plan subject to Title IV of ERISA, the assets of each
such plan are at least equal in value to the present value of accrued benefits
determined on an ongoing basis as of the date hereof.  With respect to each
Employee Benefit Plan described in Section 501(c)(9) of the Code, the assets of
each such plan are at least equal in value to the present value of accrued
benefits, based upon the most


                                      12
<PAGE>   19
recent actuarial valuation as of a date no more than ninety (90) days prior to
the date hereof.  Schedule 5.19(g) contains a complete and accurate statement
of all actuarial assumptions applied to determine the present value of accrued
benefits under all Employee Benefit Plans subject to actuarial assumptions.

                 (8)      Excise Taxes.  Neither Seller nor any member of a
Controlled Group has any liability to pay excise taxes with respect to any
Employee Benefit Plan under applicable provisions of the Code or ERISA.

                 (9)      Multiemployer Plans.  Neither Seller nor any member
of a Controlled Group is or ever has been obligated to contribute to a
multiemployer plan within the meaning of Section 3(37) of ERISA or any other
Employee Benefit Plan which has been subject to Title IV of ERISA or Section
412 of the Code.

                 (10)     PBGC.  No facts or circumstances exist that would
result in the imposition of liability against APPM, Buyer or any of its
Affiliates by the Pension Benefit Guaranty Corporation ("PBGC") as a result of
any act or omission by Seller or any member of a Controlled Group.  No
reportable event (within the meaning of Section 4043 of ERISA) for which the
notice requirement has not been waived has occurred with respect to any
Employee Benefit Plan subject to the requirements of Title IV of ERISA.

                 (11)     Retirees.  Seller has no obligation or commitment to
provide medical, dental or life insurance benefits to or on behalf of any of
its employees who may retire or any of its former employees who have retired
except as may be required pursuant to the continuation of coverage provisions
of Section 4980B of the Code and the applicable provisions of ERISA.

                 (12)     Other Compensation Arrangements.  Except as set forth
in Schedule 5.19(l), neither Seller nor any Principal Stockholder or Physician
Employee of Seller is a party to any compensation or debt arrangement with any
Person relating to the provision of health care related services other than
arrangements with Seller.

         Section 1.30     Lease Agreements.  Schedule 5.20 contains a true,
accurate and complete list of all the lease agreements and license agreements
to which Seller or any Seller Subsidiary is a party and pursuant to which
Seller or any Seller Subsidiary leases (whether as lessor or lessee) or
licenses (whether as licensor or licensee) any real or personal property
related to the operation of its business and which requires payments in excess
of $10,000 per year (the "Lease Agreements").  Seller has delivered to Buyer
true and complete copies of all of the Lease Agreements.  Each Lease Agreement
is valid, effective and in full force in accordance with its terms, and there
is not under any such lease (i) any existing or claimed material default by
Seller or any Seller Subsidiary (as applicable) or event of material default or
event which with notice or lapse of time, or both, would constitute a material
default by Seller or any Seller Subsidiary (as applicable) and, individually or
in the aggregate, result in a Material Adverse Effect on Seller; or (ii) any
existing material default by any other party under any of the Lease Agreements
or, to the knowledge of Seller, any event of material default or event which
with notice or lapse of time, or both, would constitute a material default by
any such party.  There is no pending or threatened reassessment of any property
covered by the Lease Agreements.  Seller or a Seller Subsidiary (as applicable)
has obtained the consent of each landlord or lessor whose consent is required
to the assignment of the Lease Agreements and has delivered to Buyer in writing
such consents as are necessary to effect a valid and binding transfer or
assignment of Seller's or any Seller Subsidiary's rights thereunder.  Seller
has a good, clear, valid and enforceable leasehold interest under each of the
Lease Agreements.  The Lease Agreements are in compliance with all applicable
safe harbor provisions promulgated by the Department of Health and Human
Services in connection with the enforcement of the federal Fraud and Abuse
Statute, 42 CFR Part 1001 and any similar applicable state law safe harbor or
other exemption provisions.

permit, certificate, license, approval, registration or authorization required
pursuant to any Environmental Law in connection with the conduct of its
business; or (iii) alleged illegal Regulated Activity (as defined in subsection
(e) below) by Seller.

                 (2)      Neither Seller nor any Seller Subsidiary has used,
transported, disposed of or arranged for the disposal of (as those terms are
defined in and construed under the Comprehensive Environmental Response,
Compensation and Liability Act) any Hazardous Substance (as defined herein in
subsection (e) below) that would give rise to any Environmental Liabilities (as
defined in subsection (e) below) for Seller under any applicable Environmental
Law that had, or could likely have, a Material Adverse Effect on Seller.
Neither Seller nor any Seller Subsidiary has engaged in any activity or failed
to undertake any activity which action or failure to act has given, or could
likely give, rise to any Environmental Liabilities or enforcement action by any
federal, state or local regulatory agency or authority, or has resulted, or
could likely result, in any fine or penalty imposed pursuant to any
Environmental Law.  Schedule 5.22(b) discloses any known presence of asbestos
in or on Seller's or any Seller Subsidiary's owned or leased premises.  There
is no friable asbestos in or on Seller's or any Seller Subsidiary's owned or

Material Adverse Effect on Seller.

                 (4)      Schedule 5.22(d) contains a list of all environmental
audits and other similar reports which have been prepared by, for or concerning

filings of any kind or nature necessary to be filed by Seller with any
governmental agency or authority have been properly completed and timely filed
in compliance with all applicable requirements, except where failure to so file
would not have a Material Adverse Effect on Seller.

         Section 1.34     Insurance Policies.  Schedule 5.24 lists and briefly
describes Seller's policies of insurance to which Seller or any Affiliate is a
party or under which Seller or any Affiliate, officer or director thereof is or
has been covered at any time during the last five (5) years preceding the date
of this Agreement relating to the business of Seller or any of its Affiliates
(the "Insurance Policies").  Except as set forth in Schedule 5.24, all of the
Insurance Policies are issued by insurers that are financially sound and
reputable and are valid, outstanding and enforceable policies, except as may be
limited by applicable bankruptcy, insolvency or similar laws affecting
creditors' rights generally or the availability of equitable remedies and all
premiums with respect thereto are currently paid.  All Insurance Policies
currently maintained by Seller or any Affiliate thereof ("Current Policies")
taken together (i) provide adequate insurance coverage for the assets,
properties and operations of Seller and its Affiliates for all risks normally
insured against by a Person carrying on a substantially similar business or
businesses as Seller and its Affiliates; (ii) are sufficient for compliance
with legal and contractual requirements to which Seller or any of its
Affiliates is a party or by which any of them may be bound; and (iii) shall be
maintained in force (including the payment of all premiums and compliance with
their terms without interruption up to and including the date hereof.  True,
complete and correct copies of all Insurance Policies have been provided to
APPM.  Except as set forth in Schedule 5.24, neither Seller nor any of its
Affiliates nor any officer or director thereof has received any notice or other
communication from any issuer of any Current Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, or
materially increasing the annual or other premiums payable thereunder and, to
the knowledge of Seller and the Principal Stockholders, no such cancellation or
increase of deductibles, retainages or premiums is threatened.  Except as set
forth in Schedule 5.24, there are no outstanding claims, settlements or
premiums owed against any Insurance Policy, and all required notices have been
given and all potential or actual claims under any Insurance Policy have been
presented in due and timely fashion.  Except as set forth in Schedule 5.24,
since January 1, 1993, neither Seller nor any Affiliate thereof has filed a
written application for any professional liability insurance coverage which has
been denied by an insurance agency or carrier.  Schedule 5.24 also sets forth a
list of all claims under any Insurance Policy in excess of $10,000 per
occurrence filed by Seller or any Affiliate thereof during the immediately
preceding three-year period.  Except as set forth in Schedule 5.24, each
Physician Employee has, at all times while a Physician Employee, maintained or
been covered by professional malpractice insurance in such types and amounts as
customary for such a physician practicing the same type of medicine in the same
geographic area.

                 (1)      Attached hereto as Schedule 5.25(a) is a list and
aging of all accounts receivable of Seller as of February 28, 1998, which list

receivable arose in the ordinary course of business and have not been
previously written off as bad debts and, are, to the extent still uncollected,
collectible in the ordinary course of business, net of contractual allowances,
reserves for doubtful and uncollectible accounts shown in Seller Financial
Statements or on the accounting records of Seller (which reserves are adequate
and calculated consistent with past practice).

                 (2)      Schedule 5.25(b) sets forth a true, correct and
complete list of the names and addresses of each Payor including, but not
limited to, all private-pay patients as a single Payor, of Seller which
accounted 

                                      15
<PAGE>   22
for more than 5% of the revenues of Seller in the fiscal year ended February
28, 1998, or which is reasonably expected to account for more than 5% of the
revenues of Seller for the fiscal year ended December 31, 1998.  Except as set
forth in Schedule 5.25(b), Seller has satisfactory relations with such Payors
and none of such Payors has notified Seller that it intends to discontinue its
relationship with Seller or to deny any payments due from, or any claims for
payment submitted to any such party.

         Section 1.36     Suppliers.

                 (1)      Intentionally Omitted.

Employee providers of care to patients) which accounted for a dollar volume of
purchases paid for by Seller in excess of $2,500 for the fiscal year ended
December 31, 1997, or which is reasonably expected to account for a dollar
volume of purchases paid for by Seller in excess of $2,500 for the fiscal year
ended December 31, 1998.

         Section 1.37     Intentionally Omitted.

each Physician Employee and other licensed employee or independent contractor

permits, registrations, qualifications and other rights and authorizations
required by law, ordinance, regulation or ruling of any governmental regulatory
authority necessary to operate its/his/her business and (ii) is certified for
participation under Titles XVIII and XIX of the Social Security Act (the
"Medicare and Medicaid Programs") (Medicare and Medicaid Programs and such
other similar federal, state or local reimbursement or governmental programs
for which Seller is eligible are hereinafter referred to collectively as the
"Governmental Programs") and has current provider numbers for such Governmental
Programs and with such private non-governmental programs (including without
limitation any private insurance program) under which Seller is presently
receiving payments directly or indirectly from any Payor for patient care (such
non-governmental programs herein referred to as "Private Programs").  A true,
correct and complete list of such licenses, permits and other authorizations,
and provider agreements, is set forth in Schedule 5.28(a), true, complete and
correct copies of which have been provided to APPM.  No violation, default,
order or deficiency exists with respect to any of the items listed in Schedule
5.28(a) except for such violations, defaults, orders or deficiencies which
would not be reasonably likely to have a Material Adverse Effect on Seller, and
there is no action pending or recommended by any state or federal agencies
having jurisdiction over the items listed in Schedule 5.28(a), either to
revoke, withdraw or suspend any material license or to terminate the
participation of Seller in any Governmental Program or Private Program, and no
event has occurred which, with or without notice or lapse of time, or both,
would constitute grounds for a violation, order or deficiency with respect to
any of the items listed in Schedule 5.28(a) or to revoke, withdraw or suspend
any material license to operate its business as is presently being conducted by
it.  To the knowledge of Seller, there has been no decision not to renew any
existing agreement with any provider or Payor relating to Seller's business as
presently being conducted by it.  Except as set forth in Schedule 5.28(a) or
Schedule 5.12 hereof, neither Seller nor any Physician Employee (i) has had
his/her/its professional license, Drug Enforcement Agency number,
Medicare/Medicaid provider status or staff privileges at any hospital or
diagnostic imaging center suspended, relinquished, terminated or revoked; (ii)
has been reprimanded, sentenced, or disciplined by any licensing board, state
agency, regulatory body or authority, hospital, Payor or specialty board; or
(iii) has had a final judgment or settlement entered against him/her/its in
connection with a malpractice or similar action.

                 (2)      Except as set forth in Schedule 5.28(b), Seller is
not required, and for the 72-month period prior to the Effective Time was not
required, to file any cost reports or other reports with any Governmental
Program or Private Program.

         Section 1.39     Inspections and Investigations.  Neither the right of
Seller, or any Physician Employee, nor the right of any licensed professional
or other individual affiliated with Seller to receive reimbursements pursuant
to any Governmental Program or Private Program has been terminated or otherwise
materially and adversely affected as a result of any investigation or action
whether by any federal or state governmental regulatory authority or other
third party.  Except as set forth and described in Schedule 5.29, no Physician
Employee, licensed professional or other individual affiliated with the
business has, during the past three (3) years prior to the Effective Time, had
their license suspended or revoked by any governmental regulatory authority or
agency, hospital, integrated delivery system, trade association, professional
review organization, accrediting organization or certifying agency.  True,
correct and complete copies of all reports, correspondence, notices and other
documents relating to any matter described or referenced in Schedule 5.29 have
been provided to Buyer.

         Section 1.40     Proprietary Rights and Information.

designations, including common law rights, registrations and applications
therefor, currently owned in whole or part, or used by Seller or any of its
Affiliates; (ii) all patents and applications therefor and inventories and
discoveries that may be patentable currently owned, in whole or in part, or

assignments thereof to which Seller or any of its Affiliates are a party; (iv)
all copyrights (for published and unpublished works) currently owned in whole
or part, or used by Seller or any of its Affiliates; and (v) other similar
agreements relating to the foregoing to which Seller or any of its affiliates
is a party (including expiration date if applicable) (collectively, the
"Proprietary Rights").

                 (2)      Schedule 5.30(b) contains a complete and accurate
list and summary description of all agreements relating to technology, trade
secrets, know-how or processes that Seller is licensed or authorized to use by
others (other than technology, know-how or processes generally available to
other health care providers) or which it licenses or authorizes others to use,
true, correct and complete copies of which have been provided to Buyer or APPM.
There are no outstanding or, to Seller's knowledge, threatened disputes or
disagreements with respect to any such agreement.

                 (3)      Seller owns or has the legal right to use the
Proprietary Rights without conflicting with, infringing or violating the rights
of any other person.  Except as disclosed in Schedule 5.30(c), no consent of
any person will be required for the use thereof by Buyer or APPM upon
consummation of the transactions contemplated hereby and the Proprietary Rights
are freely transferable.  No claim has been asserted by any person to the
ownership of or for infringement by Seller of any Proprietary Right of any
other Person, and neither Seller nor any Principal Stockholder is aware of any
valid basis for any such claim.  To the best knowledge of Seller, no
proceedings have been threatened which challenge the Proprietary Rights of
Seller.  Seller has the right to use, free and clear of any adverse claims or
rights of others, all trade secrets, customer lists and proprietary information
required for the performance and marketing of all merchandise and services
formerly or presently sold or marketed by them.

         Section 1.41     Taxes.

all Tax Returns and reports required to be filed by the United States or any
state or any political 


                                      17

reports are complete and accurate in all material respects and properly reflect
the taxes of Seller for the periods covered thereby.

the payment of any tax, assessment or governmental charge.

                 (3)      No Pending Deficiencies, Delinquencies, Assessments
or Audits.  Except as set forth in Schedule 5.31(c), Seller has not received
any notice that any tax deficiency or delinquency has been asserted against
Seller, and to the best knowledge of Seller, there is no threat of such
assertion.  There is no unpaid assessment, proposal for additional taxes,
deficiency or delinquency in the payment of any of the taxes of Seller that
could be asserted by any taxing authority.  Since January 1, 1993, there has
been no taxing authority audit and there is no taxing authority audit of Seller
pending, or to the actual knowledge of Seller, threatened against Seller or any
Seller Subsidiary (and the results of any completed audits are properly
reflected in Seller Financial Statements).  Seller has not violated any

required to be withheld by Seller and paid to governmental agencies for all

taxes have been collected or withheld and timely paid to the respective

1445(f)(3) of the Code and Treasury Regulations Section 1.1445-2.

                 (7)      Safe Harbor Lease.  None of the properties or assets
of Seller constitutes property that Seller, APPM, Buyer or any Affiliate of
APPM, will be required to treat as being owned by another person pursuant to

repeal by the Tax Equity and Fiscal Responsibility Act of 1982.

                 (8)      Tax Exempt Entity.  None of the assets or properties

payment" within the meaning of Section 280G of the Code.

                 (12)     S Corporation.  Seller has not made an election to be
taxed as an "S" corporation under Section 1362(a) of the Code.

not been a personal holding company within the meaning of Section 542 of the
Code.

         Section 1.42     Related Party Arrangements.  Schedule 5.32 sets forth
a description of any interest held, directly or indirectly, by any officer,
director or other Affiliate of Seller in any property, real or personal or
mixed, tangible or intangible, used in or pertaining to Seller's business and
any arrangement or agreement with any such Person concerning the provision of
goods or services or other matters pertaining to Seller's business.  There is
no commitment to, and no income reflected in Seller Financial Statements that

judgment, injunction, order or decree binding upon Seller, any Seller
Subsidiary or officer, director or key employee (including, but not limited to,
Physician Employees) of Seller or Seller Subsidiary, which has or reasonably
could be expected to have the effect of prohibiting or materially impairing any
current or future business practice of Seller or any Seller Subsidiary, any
acquisition of property by Seller, any Seller Subsidiary or the conduct of
business by Seller or any Seller Subsidiary.

         Section 1.46     Agreements in Full Force and Effect.  Except as

Affiliates (collectively, the "Buyer Indemnitees") harmless from and against

such representation or warranty) or covenant of Seller contained herein or in
any Schedule or certificate delivered hereunder;

                 (2)      any violation (or alleged violation) by Seller and/or
any of its past or present directors, officers, partners, shareholders,

and abuse (including, but not limited to, fraud and abuse in the Medicare and

or obligation (or alleged overpayment or obligation) arising out of or

any Seller Subsidiary) or any Principal Stockholder, and provided to APPM or

         Section 1.68     Conditions of Indemnification.  All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                 (1)      A party claiming indemnification under this Agreement
(an "Indemnified Party") shall promptly (and, in any event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party from whom indemnification is sought (the
"Indemnifying Party") of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying
Party a written notice ("Claim Notice") describing in reasonable detail the
nature of the Third Party Claim, a copy of all papers served with respect to
such claim (if any), an estimate of the amount of Damages attributable to the
Third Party Claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.  Except as set forth in Section 14.6, the
failure to promptly deliver a Claim Notice shall not relieve the Indemnifying
Party of its obligations to the Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim.

                          Within thirty (30) days after receipt of any Claim
Notice (the "Election Period"), the Indemnifying Party shall notify the
Indemnified Party (i) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article XIV with respect to such
Third Party Claim; and (ii) whether the Indemnifying Party desires, at the sole
cost and expense of the Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

                 (2)      If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at its sole cost and expense, such Third Party Claim by
all appropriate proceedings, which proceedings shall be prosecuted diligently
by the Indemnifying Party to a final conclusion or settled at the discretion of
the Indemnifying Party in accordance with this Section 14.3(b).  The
Indemnifying Party shall have full control of such defense and proceedings,
including any compromise or settlement thereof.  The Indemnified Party is
hereby authorized, at the sole cost and expense of the Indemnifying Party (but
only if the Indemnified Party is entitled to indemnification hereunder), to
file, during the Election Period, any motion, answer or other pleadings that
the Indemnified Party shall deem necessary or appropriate to protect its
interests or those of the Indemnifying Party and not prejudicial to the
Indemnifying Party (it being understood and agreed that if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to such Third Party Claim).  If
requested by the Indemnifying Party, the Indemnified Party agrees, at the sole
cost and expense of the Indemnifying Party, to cooperate with the Indemnifying
Party and its counsel in contesting any Third Party Claim that the Indemnifying
Party elects to contest, including, without limitation, the making of any
related counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to this Section 14.3(b) and shall bear its
own costs and expenses with respect to such participation; provided, however,
that if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.

<PAGE>   32
                 (3)      If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes its
potential liability to the Indemnified Party under this Article XIV and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnified Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to it that are different from or additional to those available to the
Indemnified Party, then the Indemnifying Party may employ separate counsel and
upon written notification thereof, the Indemnified Party shall not have the
right to assume the defense of such action on behalf of the Indemnifying Party.

                 (4)      In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction if the parties do
not reach a settlement of such dispute within thirty (30) days after notice of
a dispute is given.

                 (5)      Payments of all amounts owing by an Indemnifying
Party pursuant to this Article XIV relating to a Third Party Claim shall be
made within thirty (30) days after the latest of (i) the settlement of such
Third Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim, or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by an
Indemnifying Party pursuant to Section 14.3(d) shall be made within 30 days
after the later of (i) the expiration of the 60-day Indemnity Notice period or
(ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                 (6)      Notwithstanding any provision herein to the contrary,
the obligation of APPM or Buyer, on the one hand, or Seller or any Principal
Stockholder, on the other hand, to provide indemnification for breach of any
representation or warranty as provided in Section 14.1(a) or Section 14.2(a)
hereof shall not take effect unless and until the Damages asserted against or
incurred in the aggregate and on a collective basis by APPM or Buyer, on the
one hand, or Seller, on the other hand, as a result of such a breach or
breaches exceeds 


                                      26
<PAGE>   33
$5,000.00, and then such Indemnifying Party shall indemnify the Indemnified
Party to the full amount of such Damages.

         Section 1.69     Remedies Not Exclusive.

                 (1)      The remedies provided in this Agreement shall not be
exclusive of any other rights or remedies available to one party against the
other, either at law or in equity.

         Section 1.70     Costs, Expenses and Legal Fees.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement or (b) proving that another party breached
any of the terms of this Agreement.

         Section 1.71     Tax Benefits; Insurance Proceeds.  The total amount
of any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds, and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

         Section 1.72     Commencing Actions.  Any action against any party
hereto that is not commenced on or before the third anniversary of the Closing
Date shall be deemed waived, and no person shall have any remedy against any
party therefor; provided, however, that actions by Buyer or APPM against any
Seller or Principal Stockholder may be commenced at any time with respect to
actions (i) that constitute fraud or intentional misrepresentation by any
Seller or Principal Stockholder; (ii) that result from the failure of any
Seller or Principal Stockholder to pay any taxes or any penalties, assessments
or interest thereon; (iii) that result from the failure of any Seller or
Principal Stockholder to deliver to Buyer or APPM good, valid and marketable
title to the Purchased Assets; or (iv) that result from any breach of Section
5.13 or Section 5.22 or any misrepresentation relating to the representations
and warranties set forth therein.

                                  ARTICLE XVI
                   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

         Section 1.73     Non-Disclosure Covenant.  Seller recognizes and
acknowledges that it has in the past, currently has, and in the future may
possibly have, access to certain Confidential Information of APPM that is
valuable, special and unique assets of APPM's businesses.  Seller shall not
disclose such Confidential Information to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, unless (i)
such information becomes available to or known by the public generally through
no fault of Seller; (ii) disclosure is required by law or the order of any
governmental authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii), Seller shall, if possible, give
prior written notice thereof to APPM and provide APPM with the opportunity to
contest such disclosure; or (iii) the disclosing party reasonably believes that
such disclosure is required by applicable law in connection with the defense of
a lawsuit against the disclosing party.  In the event of a breach or threatened
breach by Seller of the provisions of this Section, APPM shall be entitled to
an injunction restraining the other party, as the case may be, from disclosing,
in whole or in part, such Confidential Information.  Nothing herein shall be
construed as prohibiting APPM from pursuing any other available remedy for such
breach or threatened breach, including the recovery of damages.

<PAGE>   34
         Section 1.74     Damages.  Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
they would have no other adequate remedy, Seller agrees that, in the event of a
breach by it of the foregoing covenant, the covenant may be enforced against it
by injunctions and restraining orders.

         Section 1.75     Survival.  The obligations of Seller under this
Article XVI shall survive the consummation of the transactions as described in
this Agreement.

                                  ARTICLE XVII
                                 MISCELLANEOUS

         Section 1.76     Amendment; Waivers.  This Agreement may be amended,
modified or supplemented only by an instrument in writing executed by all the
parties hereto.  Any waiver of any terms and conditions hereof must be in
writing, and signed by the parties hereto.  The waiver of any of the terms and
conditions of this Agreement shall not be construed as a waiver of any other
terms and conditions hereof.

         Section 1.77     Assignment.  Neither this Agreement nor any right
created hereby or in any agreement entered into in connection with the
transactions contemplated hereby shall be assignable by any party hereto,
except by APPM to a wholly owned subsidiary of APPM, provided that any such
assignment shall not relieve APPM of its obligations hereunder.

         Section 1.78     Parties in Interest; No Third Party Beneficiaries.
Except as otherwise provided herein, the terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and assigns of the parties hereto.  Neither this
Agreement nor any other agreement contemplated hereby shall be deemed to confer
upon any Person not a party hereto or thereto any rights or remedies hereunder
or thereunder.

         Section 1.79     Entire Agreement.  This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding
the subject matter hereof, and supersede all prior agreements and
understandings, both written and oral, among the parties, or any of them, with
respect to the subject matter hereof.

         Section 1.80     Severability.  If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws
effective during the term hereof, such provision shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
therefrom.  Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         Section 1.81     Survival of Representations, Warranties, Covenants
and Indemnifications.  The representations, warranties, covenants,
indemnifications, and undertakings contained herein shall survive the
