and Seller has delivered to APPM true and complete copies, of each contract,

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

other Person currently contemplates, any amendment or change to any such
contract, agreement or instrument.

              (a)    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.

              (b)    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.

              (c)    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.

              (d)    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.

              (e)    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

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





                                       17
<PAGE>   24
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.

              (g)    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 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.

Controlled Group is or ever has been obligated to contribute to a multiemployer

Plan which has been subject to Title IV of ERISA or Section 412 of the Code.

              (j)    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.

              (k)    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.

              (l)    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 5.20  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





                                       18
<PAGE>   25
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.  To the
knowledge of Seller, neither Seller nor any Principal Stockholder has received
notice of any 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.

Agreements) in real property.

                     (ii)   Except as set forth in Schedule 5.3(b), Seller and
any Seller Subsidiary (i) has good and marketable title to all of its

any rights or interests therein which it purports to own including, without
limitation, all the property and assets reflected in Seller Financial
Statements; and (ii) owns such rights, interests, assets and property free and
clear of all Encumbrances, title defects or objections (except for taxes not
yet due and payable).  Seller Financial Statements reflect all personal
property used in connection with the operation of the business subject to
disposition in the ordinary course of business and such personal property are
the necessary assets to continue operation of Seller and any Seller Subsidiary.

       Section 5.22  Environmental Matters.

              (a)    Neither Seller nor any Seller Subsidiary has, within the
five (5) years preceding the date hereof, through the Effective Time, received

entity, or any other Person, any written notice, demand, citation, summons,
complaint or order or any notice of any penalty, lien or assessment, and no
investigation or review is pending by any governmental entity, with respect to
any (i) alleged violation by Seller of any Environmental Law (as defined in
subsection (e) below); (ii) alleged failure by Seller to have any environmental
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

transported, disposed of or arranged for the disposal of (as those terms are

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,





                                       19
<PAGE>   26
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
leased premises.

              (c)    No soil or water in or under any assets currently or
formerly held for use or sale by Seller or any Seller Subsidiary is or has been

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

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

all accounts receivable of Seller as of December 15, 1997, which list is
complete, true and accurate in all material respects.  All such accounts

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 for more
than 5% of the revenues of Seller in the fiscal year ended December 31, 1997,

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.

thereto (calculated consistent with past practice), of items of a quality and a
quantity usable and saleable in the ordinary course of Seller's business and
conform to generally accepted standards in the industry of which Seller is a
part.  The value of the inventories reflected on Seller Current Balance Sheet
contained in Seller Financial Statements are net of adequate reserves for
damaged, excess, and unusable items.  Purchase commitments of Seller for
inventory are not materially in excess of normal requirements, and none of such
purchase commitments are at prices in excess of prevailing market prices at the
time of such purchase commitment.

       Section 5.28  Licenses, Authorization and Provider Programs.

              (a)    Except as listed in Schedule 5.28(a), Seller, and each
Physician Employee and other licensed employee or independent contractor of

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

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

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,

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.

              (c)    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

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

failure to pay (or alleged failure to pay) taxes.

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

              (f)    Foreign Person.  Neither Seller nor any Principal
Stockholder is a foreign person, as such term is referred to in Section
1445(f)(3) of the Code and Treasury Regulations Section 1.1445-2.

              (g)    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 the
"Safe Harbor Lease" provisions of Section 168(f)(8) of the Code prior to repeal
by the Tax Equity and Fiscal Responsibility Act of 1982.

              (h)    Tax Exempt Entity.  None of the assets or properties of
Seller are subject to a lease to a "tax exempt entity" as such term is defined
in Section 168(h)(2) of the Code.

to be made by Seller will be characterized as an "excess parachute payment"
within the meaning of Section 280G of the Code.

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

              (m)    Personal Holding Companies.  Seller is not and has not
been a personal holding company within the meaning of Section 542 of the Code.

       Section 5.32  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
has been derived from an Affiliate.  Except as set forth in Schedule 5.32, none
of the Assumed Liabilities includes any obligation of any kind or designation
to any Affiliate of Seller or the Principal Stockholders.

       Section 5.33  Banking Relations.  Set forth in Schedule 5.33 is a

       Section 5.34  Fraud and Abuse and Self Referral.  Neither Seller nor any
Seller Subsidiary has engaged and, to the knowledge of Seller, neither Seller's

regulations, or which are prohibited by applicable rules of professional
conduct.

       Section 5.35  Restrictions on Business Activities.  Except as disclosed
in Schedule 5.14 or Schedule 5.35, there is no material agreement, 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 5.36  Agreements in Full Force and Effect.  Except as expressly
set forth in Seller's Schedules to this Agreement, all contracts, agreements,
plans, leases, policies and licenses referred to, or required to be referred
to, in Seller's Schedules delivered hereunder are valid and binding, and are in
full force and effect and are enforceable in accordance with their terms,
except to the extent that the validity or enforceability thereof may be limited

generally, or by general equity principles, or by public policy.  There is no
pending or, to the knowledge of Seller, threatened bankruptcy, insolvency or
similar proceeding with respect to any other party to such agreements, and no
event has occurred which (whether with or without notice, lapse of time or the





                                       25

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

an estimate of the amount of Damages attributable to the Third Party Claim and

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

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.

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.

              (c)    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





                                       32

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.

              (d)    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.

              (e)    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.

              (f)    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 $10,000.00, and then such Indemnifying Party shall indemnify
the Indemnified Party to the full amount of such Damages.

              (g)    Notwithstanding any provision herein to the contrary, the
Principal Stockholders shall not have any liability to Buyer or APPM under this
Agreement after the Principal Stockholders have, collectively, paid to Buyer or
APPM pursuant to this Article XIV indemnification payments in an aggregate
amount (together with the applicable value (as determined pursuant to Section
14(c)) of any APPM Shares retained by APPM pursuant to Section 4.1(c)), equal
to $_______________.

       Section 14.4  Remedies Not Exclusive.

              (a)    The Buyer Indemnitees' rights to be indemnified, defended
and held harmless by Seller and the Principal Stockholders shall be the Buyer
Indemnitees' exclusive remedy against Seller and the Principal Stockholders for
matters arising out of this Agreement; provided, however, that the limitation
set forth in this sentence shall not limit any Buyer Indemnitee's remedies
against Seller and the Principal





                                       33
<PAGE>   41
Stockholders for matters arising out of this Agreement that constitute fraud or
intentional misrepresentation by any Seller or Principal Stockholder, failure
of any Seller or Principal Stockholder to deliver to Buyer or APPM good, valid
and marketable title to the Purchased Assets, or failure of any Seller or
Principal Stockholder to pay any taxes or any penalties, assessments or
interest relating thereto.  This Section shall not limit APPM's right to
injunctive relief against a breach by any Seller or Principal Stockholder of
any covenant set forth in this Agreement.

              (b)    The Seller Indemnitees' rights to be indemnified, defended
and held harmless by Buyer and APPM shall be the Seller Indemnitees' exclusive
remedy against Buyer and APPM for matters arising out of this Agreement;
provided, however, that the limitation set forth in this sentence shall not
limit any Seller Indemnitee's remedies against Buyer or APPM for matters
arising out of this Agreement that constitute fraud or intentional
misrepresentation by Buyer or APPM.  This Section shall not limit Seller's
right to injunctive relief against a breach by APPM or Buyer of any covenant
set forth in this Agreement.

              (c)    Except as set forth in Sections 14.4(a) or 14.4(b) above,
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 14.5  No Effect on Liability.  None of (i) the consummation of
the transactions contemplated by this Agreement or the Other Agreements, (ii)
the delay or omission of any party to exercise any of its rights under this
Agreement or any Other Agreement or (iii) any investigation or disclosure that
any party makes, any notice that any party gives, or any knowledge that any
party obtains as a result thereof, or otherwise, shall (A) affect the liability
of the parties to one another for breaches of this Agreement, any Other
Agreement or any related agreement between the parties hereto, or (B) prevent
any party from relying on the representations or warranties contained in this
Agreement, any Other Agreement or any related agreement between the parties
hereto.

       Section 14.6  Commencing Actions.  Any action against any party hereto
that is not commenced on or before the second 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 5.22 or
Section 5.13 or any misrepresentation relating to the representations and
warranties set forth therein.

       Section 14.7  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 14.8  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.

                                  ARTICLE XVI
                   NONDISCLOSURE OF CONFIDENTIAL INFORMATION

       Section 16.1  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.

       Section 16.2  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 16.3  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 17.1  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 17.2  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 17.3  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 17.4  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 17.5  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 17.6  Survival of Representations, Warranties and Covenants.
The representations, warranties, covenants and undertakings contained herein
shall survive the consummation of the transactions described herein and all
statements contained in any certificate, exhibit or other instrument delivered
by or on behalf of Seller, any Principal Stockholder, APPM or Buyer pursuant to
this Agreement shall be deemed to have been representations and warranties by
such Seller, such Principal Stockholder, APPM or Buyer.

       Section 17.7  Governing Law.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF MARYLAND.

       Section 17.8  Captions.  The captions in this Agreement are for
convenience of reference only and shall not limit or otherwise affect any of
the terms or provisions hereof.

       Section 17.9  Gender and Number.  When the context requires, the gender
of all words used herein shall include the masculine, feminine and neuter and
the number of all words shall include the singular and plural.

       Section 17.10 Reference to Agreement.  Use of the words "herein,"
"hereof," "hereto" and the like in this Agreement shall be construed as
references to this Agreement as a whole and not to any particular Article,
Section or provision of this Agreement, unless otherwise noted.

       Section 17.11 Confidentiality; Publicity and Disclosures.  Each party
shall keep this Agreement and its terms confidential, and shall make no press
release or public disclosure, either written or oral, regarding the
transactions contemplated by this Agreement without the prior knowledge and
consent of the other parties hereto; provided that the foregoing shall not
prohibit any disclosure (a) by press release, filing or otherwise that APPM has
determined in its good faith judgment to be required by federal securities laws
or the rules of the National Association of Securities Dealers, (b) to
attorneys, accountants, investment bankers or other agents of the parties
assisting the parties in connection with the transactions contemplated by this
Agreement and (c) by APPM in connection with conducting an examination of the
operations and assets of Seller; provided that APPM shall reasonably promptly
provide notice of any release.

       Section 17.12 Notice.  Whenever this Agreement requires or permits any
notice, request, or demand from one party to another, the notice, request or
demand must be in writing to be effective and shall be deemed to be delivered
and received (i) if personally delivered or if delivered by telex, telegram,
facsimile or courier service, when actually received by the party to whom
notice is sent; or (ii) if delivered by mail

       Section 17.13 No Waiver; Remedies.  No party hereto shall by any act
(except by written instrument pursuant to Section 17.1 hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default in or breach of any of the terms
