          (b)  If any payment to be made on or under this Term Note B-2 is
stated to be due or becomes due and payable on a day other than a Business Day,
the due date thereof shall be extended to, and such payment shall be made on,
the next succeeding Business Day and interest thereon shall be payable at the

or delivered, or any other action taken in reliance hereon, and all other
demands and notices of any description. No renewal or extension of this Term

security interests or remedies hereunder or under any of the Loan Documents or
under applicable law or otherwise.

          (b)  The enumeration of the foregoing rights and remedies is not
intended to be exhaustive. The rights and remedies of Lender described herein

otherwise, shall the interest and other charges paid or agreed to be paid to the

maximum rate permissible under applicable law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto. If due to
any circumstance whatsoever, fulfillment of any provision hereof, at the time
performance of such provision shall be due, shall exceed any such limit, then,
the obligation to be so fulfilled shall be reduced to such lawful limit, and if
the Lender shall have received interest, or any other payment of any kind which
might be deemed to be interest under applicable law in excess of the highest
maximum lawful rate, then such excess amount shall be applied first to any
unpaid fees and charges hereunder, then to unpaid principal balance owed by the
Company hereunder, and if the then remaining excess interest is greater than the
previously unpaid principal balance hereunder, Lender shall promptly refund such
excess amount to the Company and the provisions hereof shall be deemed amended
to provide for such permissible rate. The terms and provisions of this SECTION
10 shall control to the extent any other provision of this Term Note B-2 or any
Loan Document is inconsistent herewith.

     11.  GOVERNING LAW. This Term Note B-2 shall be governed by and construed
in accordance with the internal laws of the State of New York without giving
effect to its choice of laws rules (other than Section 5-1401 of the New York
General Obligation Law).

subrogated to the rights of Lender hereunder or under the Loan Agreement unless
and until the Obligations have been performed in full and paid irrevocably in
full in cash and the Loan Agreement has been terminated.

          (b) Section 2.14 of the Loan Agreement contains certain terms and
conditions under which all or a portion of the amounts due hereunder must be
prepaid by the Company to Lender.

     7. METHOD OF PAYMENT; PAYMENTS DUE ON A DAY OTHER THAN A BUSINESS DAY.

          (a) Principal, interest and any fees or other amounts owed hereunder
shall be paid to the Lender, by wire transfer, in lawful money of the United
States of America on the date when due without offset or counterclaim in
immediately available funds. Each Advance made by the Lender to the Company, and
all payments made on account of principal thereof, shall be recorded by the
Lender and, prior to any permitted transfer hereof, endorsed on SCHEDULE A
attached hereto which is part of this Bridge Note; PROVIDED, HOWEVER, that the
failure to make any such recordation or endorsement shall not affect or in any
way discharge or release the obligations of the Company under this Bridge Note.

          (b) If any payment to be made on or under this Bridge Note is stated
to be due or becomes due and payable on a day other than a Business Day, the due
date thereof shall be extended to, and such payment shall be made on, the next
succeeding Business Day and interest thereon shall be payable at the applicable
rate during such extension and such extension of time

                                       -2-
<Page>

in such case shall be included in the computation of payment of any interest
and/or fees, as the case may be.

     8. WAIVERS. The Company hereby waives presentment, protest, demand, notice
of dishonor or non-payments, as well as all defenses with respect to this Bridge
Note, the Loan Agreement and/or any Obligation, notice of acceptance hereof,
notice of loans or Advances made, credit extended, collateral received or
delivered, or any other action taken in reliance hereon, and all other demands
and notices of any description. No renewal or extension of this Bridge Note, the
Loan Agreement or any rights hereunder or thereunder, no release of the Company
or any Guarantor, or delay or omission on Lender's part in enforcing this Bridge
Note or any other Loan Document or in exercising or enforcing any right, remedy,
option or power hereunder or under any other Loan Document, shall affect the
liability of the Company or any Guarantor or operate as a waiver of such or any
other right, remedy, power or option or of any default. The pleading of any
statute of limitations as a defense to any demand against the Company is
expressly waived by the Company.

     9. EXERCISE OF RIGHTS.

          (a) Lender shall have the right in its sole discretion to determine
which rights, powers, Liens, security interests or remedies Lender may at any
time pursue, relinquish, subordinate or modify or to take any other action with
respect thereto, and such determination will not in any way modify or affect any
of Lender's rights, powers, Liens, security interests or remedies hereunder or
under any of the Loan Documents or under applicable law or otherwise.

          (b) The enumeration of the foregoing rights and remedies is not
intended to be exhaustive. The rights and remedies of Lender described herein
are cumulative and are not alternative to or exclusive of any other rights or
remedies which Lender otherwise may have by contract or at law or in equity, and
the partial or complete exercise of any right or remedy shall not preclude any
other further exercise of such or any other right or remedy.

     10. LAWFUL LIMITS. This Bridge Note is hereby expressly limited so that in
no contingency or event whatsoever, whether by reason of acceleration or
otherwise, shall the interest and other charges paid or agreed to be paid to the
Lender for the use, forbearance or detention of money hereunder exceed the
maximum rate permissible under applicable law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto. If due to
any circumstance whatsoever, fulfillment of any provision hereof, at the time
performance of such provision shall be due, shall exceed any such limit, then,
the obligation to be so fulfilled shall be reduced to such lawful limit, and if
the Lender shall have received interest, or any other payment of any kind which
might be deemed to be interest under applicable law in excess of the highest
maximum lawful rate, then such excess amount shall be applied first to any
unpaid fees and charges hereunder, then to unpaid principal balance owed by the
Company hereunder, and if the then remaining excess interest is greater than the
previously unpaid principal balance hereunder, Lender shall promptly refund such
excess amount to the Company and the provisions hereof shall be deemed amended
to provide for such permissible rate. The terms and provisions of this SECTION
10 shall control to the extent any other provision of this Bridge Note or any
Loan Document is inconsistent herewith.

                                       -3-

     11. GOVERNING LAW. This Bridge Note shall be governed by and construed in
accordance with the internal laws of the State of New York without giving effect
to its choice of laws rules (other than Section 5-1401 of the New York General
Obligation Law).

the event an HMO Subsidiary seeks to enter into a Subcapitation Arrangement, the
HMO Subsidiary shall notify APS at least 90 days prior to the proposed effective
date of such arrangement and shall use commercially reasonable efforts to offer,
on terms reasonably acceptable to the applicable HMO Subsidiary and provider
sponsored networks, APS an opportunity to provide or administer the mental
health/substance abuse component under such arrangement. APS may accept or
reject any such offer in its sole discretion. If APS is not engaged to provide
or administer the behavioral health component under any such Subcapitation
Arrangement, the applicable HMO Subsidiary may nevertheless enter into such
Subcapitation Arrangement and terminate this Agreement with respect to the
Capitated Members covered thereunder.

      4.3.  GEOGRAPHIC ACCESS.

            4.3.1 NETWORK CONFIGURATION. APS shall configure its network of MHSA

that HMO Subsidiary's

                                       12

Service Area. In the event an HMO Subsidiary reasonably determines that there
are not sufficient MHSA Providers to provide MHSA Services to Members, an HMO
Subsidiary shall notify APS of the alleged deficiency and within 30 days, the
HMO Subsidiary and APS shall meet to assess the alleged deficiency, and if
appropriate, develop a mutually satisfactory plan of correction. The adequacy of
APS' network of MHSA Providers and Members' accessibility to MHSA Providers
shall be measured in accordance with Section 4.8.3 of this Agreement and the
Provider Availability and Provider Accessibility Standards set forth in
Attachment D-1, Goal Performance Standards to the Agreement.

            4.3.2 SERVICE AREA MODIFICATION. HMO Subsidiary shall notify APS in
writing as soon as practicable but in no event later than 30 days prior to any
modification to its Service Area. In the event of any expansion to the Service
Area, APS shall arrange, as required under this Agreement, for MHSA Providers in
proportion to reasonably anticipated enrollment in such expanded Service Area
within 90 days of receiving notice of such Service Area expansion, at which time
the definition of Service Area in this Agreement shall include such expansion
without further compliance with SECTION 17.1. Notwithstanding the foregoing, the
adequacy of APS' network of MHSA Providers and Members' accessibility to MHSA
Providers shall be measured in accordance with the actual results reported
pursuant to Section 4.8.3 as compared to the Provider Availability and Provider
Accessibility Standards set forth in Attachment D-1, Goal Performance Standards.
Nothing in this Section 4.3.2 shall be deemed or construed as relieving HMO
Subsidiaries' of their respective obligations to notify APS of their active
Service Areas pursuant to Exhibit 1 to Attachment D-1, Goal Performance
Standards.

      4.4.  APS TRIAGE OF CARE.

            A 24-hour toll-free telephone line shall be available for Members.
During regular business hours, services provided through such phone line shall
include referral of Members for required MHSA Services, and responding to Member
inquiries and questions regarding MHSA Services. Outside of regular business
hours, services provided through such phone line shall include crisis
intervention and referrals for Emergency MHSA Services. The services of an
appropriately qualified behavioral health care professional shall be available
through such telephone line.

      4.5.  PROVISION OF MHSA SERVICES AND UM SERVICES.

            4.5.1 GENERALLY. APS shall provide or arrange for the provision of
MHSA Services and UM Services to Members pursuant to this Agreement beginning on
the Effective Date.

            4.5.2 REVIEW OF MEDICAL NECESSITY. APS shall develop and apply
standards of Medical Necessity, appropriateness and efficiency which reflect
patterns of care found in established managed behavioral health care
environments and that are consistent with the applicable Benefit Contract. APS
shall involve an appropriately licensed behavioral health care professional
whenever rendering a recommendation that mental health and/or substance abuse
services that have been requested or for which payment has been requested are
not Medically Necessary consistent with the applicable Benefit Contract. In the
event of a dispute regarding

                                       13
<PAGE>

whether requested services are Medically Necessary, such dispute shall be
resolved pursuant to SECTION 6.4. OR 6.5, as applicable.

            4.5.3 UM SERVICES GENERALLY. Each of the HMO Subsidiaries hereby
delegates to APS and APS hereby assumes responsibility for UM Services. APS
shall conduct such UM Services in accordance with protocols APS develops, which
protocols shall be approved by CHC and the HMO Subsidiaries. APS's protocols for
the provision of UM Services shall also comply with the applicable requirements
of NCQA or other Accrediting Bodies. Attachment 1-2 describes the agreement for
delegated UM Services.

            4.5.4 AUTHORIZATION OF MHSA SERVICES. APS shall have the right to
determine, consistent with the applicable Benefit Contract, the level and extent
of MHSA Services which are appropriate for the treatment of Members, including
whether MHSA Services shall be rendered on an inpatient or an outpatient basis.
APS shall have the right to require Members to receive In-Network MHSA Services
from MHSA Providers when such care can be provided consistent with the standards
of practice set forth in this SECTION 4.5, the applicable Benefit Contract and
the Performance Standards set forth in SECTION 4.8 and ATTACHMENT D. Except in
the case of MHSA Services rendered in an Emergency, or as otherwise required
under this Agreement or as agreed to by APS in writing, APS shall not in any way
be financially or otherwise responsible for providing, arranging or paying for
any mental health and/or substance abuse services APS has not authorized (unless
such lack of authorization resulted from an MHSA Provider not adhering to the
referral and authorization requirements of APS), provided, however, that in the
event of an Emergency APS shall not be liable for any continued MHSA Services
unless APS is notified within the period specified in the applicable Benefit
Contract after the Emergency MHSA Services were commenced and APS authorizes
continued MHSA Services.

            4.5.5 EFFECT OF UM SERVICES. APS shall use reasonable efforts to
advise MHSA Providers that its utilization management is a recommendation of
Medical Necessity only and not a confirmation of eligibility and/or benefit
coverage.

      4.6.  AVAILABILITY OF IN-NETWORK MHSA SERVICES.

            APS shall use commercially reasonable efforts to comply with the
following standards in arranging for the provision of In-Network MHSA Services:

            to a Member immediately in the applicable Service Area.

                  b. Urgent In-Network MHSA Services shall be made available to
            a Member in the applicable Service Area within 48 hours of the time

            be made available in the applicable Service Area to a Member within
            10 working days of the time the MHSA Services are requested.

                                       14
<PAGE>

                  d. APS shall use commercially reasonable efforts to make
            Out-of-Area MHSA Services available to Members outside their home
            Service Area but within another Service Area where APS has
            contracted with MHSA Providers.

            APS shall be deemed to be in compliance with the requirements of
this SECTION 4.6 if an appointment at two geographically appropriate MHSA
Providers is offered as available to a Member within the time period specified,
notwithstanding the Member's preference or availability for other appointment
times.

      4.7.  MIXED SERVICES.

            When a Member has a condition or illness that requires MHSA Services
and other Covered Services, APS shall be responsible for arranging and paying
for only the MHSA Covered Services and for coordinating referrals and
authorizations for non-MHSA Services with the applicable HMO Subsidiary. The HMO
Subsidiaries, the Affiliated Payor or the Member, as the case may be, shall be
responsible for payment of any non-MHSA Covered Services. In determining whether
certain services shall be considered MHSA Services or non-MHSA Covered Services,
APS and the applicable HMO Subsidiary shall refer to ATTACHMENT E.

      4.8.  PERFORMANCE STANDARDS.

            4.8.1 GENERALLY. APS shall use commercially reasonable efforts to
meet or exceed the Performance Standards set forth in ATTACHMENTS D-L AND D-2
HERETO with respect to each HMO Subsidiary and Operating Unit. The Performance
Standards are not applicable to any administration of Pre-Commencement Date IBNR
pursuant to SECTION 4.1.5. As specified in ATTACHMENTS D-L AND D-2, the
Performance Standards are divided into Goal Standards, the attainment of which
represents optimal performance and Termination Standards, which reflect the
level of performance which will provide a basis for termination of this
Agreement.

            4.8.2. REVIEW OF PERFORMANCE STANDARDS. The Performance Standards
are intended to reflect prevailing performance standards and other criteria by
which clients measure performance of the managed behavioral health care
component of the health maintenance organization industry. Accordingly, the
parties shall review the Performance Standards periodically after January 1,
2001 and if appropriate, modify them to reflect prevailing industry standards.
If the parties are unable to agree on such modifications, they will submit the
dispute to arbitration pursuant to SECTION 14.1.

            4.8.3 PERFORMANCE STANDARD REPORTING. APS shall deliver the reports
listed below to CHC and each of the HMO Subsidiaries showing APS's actual
performance during the applicable period compared with the Performance
Standards. APS shall prepare separate reports for each HMO Subsidiary and
Operating Unit showing actual performance for that HMO Subsidiary or Operating
Unit with respect to Performance Standards that can reasonably be measured
separately.

<PAGE>

                  (a) MONTHLY REPORTS. The monthly reports shall show actual
            performance compared to those Performance Standards that are
            designated on ATTACHMENTS D-1 AND D-2 as being measured on a monthly
            basis. The monthly reports shall be delivered within 25 days after
            the end of the month (unless a shorter time period is required by an
            Enrolling Unit) to which they relate with the first report for the
            month of September, 1997 being due on October 25, 1998. Monthly
            reports for the last month of a quarter shall be incorporated in the
            quarterly report for such quarter and shall be due on the due date
            for such reports;

                  (b) QUARTERLY REPORTS. The quarterly reports shall show actual
            performance compared to those Performance Standards that are
            designated on ATTACHMENTS D-1 AND D-2 as being measured on a
            quarterly basis as well as monthly Performance Standards for the
            last month of the quarter. The quarterly reports shall be delivered
            within 30 days after the end of the quarter to which they relate
            with the first report for the quarter ended September, 1997 being
            due on October 30, 1998. The report for the second and fourth
            quarters of each year shall include data with respect to Performance
            Standards, if any, designated as being measured on a semi-annual
            basis.

                  (c) ANNUAL REPORTS. The annual reports shall show actual
            performance compared to those Performance Standards that are
            designated on ATTACHMENTS D-1 AND D-2 as being measured on an annual
            basis. The annual reports shall be delivered within 45 days after
            the end of the year to which they relate with the first report for
            the year 1997 being due on February 14, 1998. Notwithstanding the
            foregoing, annual reports due for 1999 and each annual period
            thereafter shall be due on February 15.

                  If the due date for a report falls on a weekend or holiday,
            then the report shall be due on the next business day. For purposes
            of the annual report, the period reported on shall be the calendar
            year commencing January 1 and ending December 31.

            4.8.4 PLAN OF CORRECTION. If a report shows that APS has failed to
perform at or above the applicable Performance Standard for any HMO Subsidiary
or Operating Unit, CHC may, by written notice, request that APS prepare a plan
to correct such non-attainment as rapidly as practicable but In no event later
than the end of the "Deficiency Response Time" designated on ATTACHMENT D-1 OR
D-2, as applicable.

            4.8.5 PENALTY FOR NON-ATTAINMENT OF GOAL PERFORMANCE STANDARD. If,
after the expiration of the applicable cure period described in Attachment D-1,
"Goal Performance Standards," APS has failed to attain the Goal Performance
Standard, then APS shall pay CHC the penalty provided for in Attachment D-1.
Such payment from APS shall be due within thirty (30) days from the end of the
applicable cure period. In calculating the amount of the penalty, the number of
Members shall be based on the number of Members APS received Capitation Payments
for during the applicable reporting period. The penalty shall be calculated from
the first day of the cure period until the standard has been met by APS.

                                       16

            4.8.6 PERFORMANCE DEFAULT BEYOND APS' CONTROL. In the event the
operations of APS or any substantial portion thereof are interrupted by war,
fire, insurrection, labor/provider contract troubles, riots, the elements,
earthquakes, acts of God, or similar circumstance that is beyond APS control,
the provisions of this Agreement (or such portions hereof as APS is thereby
rendered incapable of performing), including CHC's obligation to compensate APS
for any services which APS is incapable of performing, shall be suspended for
the duration of such interruption. Such suspension shall not be deemed or
construed as a breach of this Agreement by APS or the failure by APS to comply
with a Goal Performance Standard.

      5.1.  QUALITY MANAGEMENT AND OTHER PROGRAMS.

            APS shall establish and maintain its own quality management program
and shall cooperate with any such reasonable and similar programs established or
required by an HMO Subsidiary or the applicable Benefit Contract with respect to
MHSA Services and/or UM Services. Each of the HMO Subsidiaries hereby delegates

shall pay from its own funds, claims for MHSA Services provided to Capitated
Members, subject to applicable Coinsurance, Copayments, and Deductibles.

Pre-Commencement Date IBNR claims or claims for MHSA Services provided to ASO
Members or other Members under arrangements where APS is not financially at risk
for utilization of MHSA Services. CHC or the applicable HMO Subsidiary or
Affiliated Payor shall be financially responsible for and shall fund payment of
such claims, and APS shall process payment for such claims, in accordance with
the funding procedures set forth on ATTACHMENT F hereto.

            6.1.4 IBNR Reserve. No later than September 25, 1998, APS shall
establish an escrow account (the "IBNR RESERVE") with a commercial bank having
capital and remained earnings of at least $250,000,000 or another financial
institution reasonably acceptable to CHC to be maintained as security for APS's
obligations under this Agreement to pay claims for MHSA Services, including any
subrogation claims of CHC or any HMO Subsidiary arising from its payment of any
such claim for MHSA Services on behalf of APS. The IBNR Reserve shall be
established pursuant to an Escrow Agreement in form and substance reasonably
acceptable to CHC and APS. Commencing on October 1, 1998 and continuing on the
first day of every month thereafter until the funds on deposit in the IBNR
Reserve aggregate at least $2,000,000, APS shall deposit into the IBNR Reserve
the following amounts: $22,000 on the first day of each mouth during the period
October 1, 1999 through September 30, 1999, $44,000 on the first day of each
month during the period October 1, 1998 through September 30, 2000 and $50,000
on the first day of each month thereafter; provided, however, that APS shall
have no further obligation to deposit amounts into the IBNR Reserve, and the
contents of the IBNR Reserve shall be delivered to APS, at such time as APS
demonstrates to CHC's reasonable satisfaction that APSH has a consolidated net
worth (determined in accordance with GAAP based upon the then most recently
prepared consolidated financial statements of APSH) of at least $2,500,000;
provided further, that if at any time thereafter the consolidated net worth of
APSH (as so determined) falls below $2,500,000, APSH shall again be obligated to
maintain the IBNR Reserve as provided in this SECTION 6.1.4. Any failure by APS
(i) to establish the IBNR Reserve on or before September 25, 1998 or (ii) to
deposit into the IBNR Reserve any amount required to be deposited pursuant
hereto shall be deemed to be a material breach by APS of a material term of this
Agreement and shall entitle CHC or any HMO Subsidiary to terminate this
Agreement in accordance with SECTION 15.2.1.

      6.2.  BENEFIT ADMINISTRATION.

            APS shall make initial determinations whether services and/or
supplies requested by or on behalf of a Member or for which a Member has
requested reimbursement are MHSA Services covered by a Member's Benefit
Contract. If a determination is made that the requested services and/or supplies
are not MHSA Services, the Member shall be advised of the determination
regarding the lack of coverage and the Member's rights under the Benefit
Contract to appeal a denial of coverage as required by the Benefit Contract and
applicable law, including ERISA.

appeal). The HMO Subsidiary or Affiliated Payor must make an attempt to resolve
the matter within 30 days but no later than 45 days following referral of the
dispute from APS. The HMO Subsidiary's or Affiliated Payor's decision shall be
binding unless the Member appeals. If the Member appeals the decision of the HMO
Subsidiary or Affiliated Payor, then the appeal shall be referred to the
appropriate state regulatory agency (or appropriate plan representative if the
Member's claim is subject to ERISA) for resolution. Such decision shall be
binding. The foregoing shall not be deemed or construed as limiting or otherwise
restricting APS's rights under Section 14.1.

financial responsibility for the provision of the services and/or supplies in
dispute, and the parties shall proceed with the dispute resolution procedure

the other parties in resolving the Dispute. An HMO Subsidiary shall, or shall
advise the Affiliated Payor to, cooperate with APS in the defense of the
Dispute, unless the HMO Subsidiary, or the Affiliated Payor and/or APS elects to
settle the Dispute, provided that no Dispute may be settled by APS without the
written consent of the applicable HMO Subsidiary or

                                       20
<PAGE>

Affiliated Payor, unless the applicable HMO Subsidiary or Affiliated Payor, as
the case may be, are not liable under such settlement and are released
unconditionally from all liability with respect to such Dispute. In the event an
HMO Subsidiary or the Affiliated Payor and APS, as the case may be, agree
regarding the terms and conditions of a settlement of the Dispute, the parties
shall perform their respective obligations under the terms of the settlement. in
the event an HMO Subsidiary or the Affiliated Payor at any time elects to scale
the Dispute and APS does not agree with the terms of the settlement, the HMO
Subsidiary or the Affiliated Payor shall pay for the provision of the services
and/or supplies in dispute, and the parties shall proceed with the dispute
resolution procedure described in SECTION 6.5. Each party shall indemnify the
other(s) in accordance with SECTION 11.2.

      6.5.  COVERAGE DISPUTE BETWEEN APS, AN HMO SUBSIDIARY OR AN AFFILIATED
            PAYOR REGARDING MEMBERS.

            In the event of a dispute between APS and an HMO Subsidiary or an
Affiliated Payor regarding whether particular services and/or supplies for a
Member are MHSA Services for which APS had or will have financial responsibility
or if an HMO Subsidiary or the Affiliated Payor enters into a settlement
agreement with a Member as a result of an actual or threatened grievance
arbitration or litigation and APS and the HMO Subsidiary or Affiliated Payor do
not agree on financial liability for such services ("COVERAGE DISPUTE"), the
respective parties shall comply with the following Coverage Dispute Resolution
Procedure.

            (a) The Coverage Dispute shall be submitted to the respective HMO
      Subsidiary's Medical Director and APS's Medical Director for review;

            (b) The Medical Directors shall issue their determination in a
      timely manner in accordance with law and the applicable Benefit Contract.
      In the event there continues to be a Coverage Dispute after review by the
      Medical Directors, the parties shall submit the Coverage Dispute to the
      MHSA Liaison Committee described in SECTION 5.3 for consideration at the
      next or at a special meeting of the MHSA Liaison Committee;

            (c) The MHSA Liaison Committee shall review the Coverage Dispute. In
      the event the parties' representatives on the Liaison Committee agree on a
      resolution of the Coverage Dispute, such resolution shall be binding on

adjustments of eligibility for previous months, subject to SECTION 2.1.3. Such
retroactive adjustments shall be made monthly.

            9.1.2 COPAYMENT EXPENSES. Neither CHC nor any HMO Subsidiary shall
have any liability if APS incurs any expense due to a Member exceeding his or
her out-of-pocket Copayment maximum, even if APS is required to reimburse an

Participation Agreement.

            9.1.3 PAYMENT OF ASO FEES. Each HMO Subsidiary shall pay APS the

<PAGE>

made each month and shall be based on the then current information available to
the HMO Subsidiary regarding the number of ASO Members for that month.

            9.1.4 TIMING OF PAYMENTS. THE HMO Subsidiaries shall pay APS the
Capitation Payments and ASO Fees no later than the 15th of the month for which
such payment is due; provided that the payments due with respect to the last 5

execution and delivery of this Agreement. Payments may be made directly by an
HMO Subsidiary or by CHC on behalf of any or all of the HMO Subsidiaries.

            9.1.5 LATE PAYMENT PENALTIES. In the event any payment due hereunder
is more than five days past due, APS may deliver a late notice to the HMO
Subsidiary responsible for such payment. In the event an aggregate past due
amount of $100,000 or more remains unpaid five days after such late notice, the
applicable HMO Subsidiary(ies) shall pay APS interest on such past due amount
from the due date through the date of payment at a rate equal to the prime rate
of a major money center bank in the City of New York reasonably selected by APS
on the date such money first became due, as reported by the Wall Street Journal,
plus 2%.

            9.1.6 CHC GUARANTEE. CHC hereby guarantees the prompt payment of all
amounts due hereunder from the HMO Subsidiaries to APS, provided that, with
respect to each HMO Subsidiary, such guarantee shall cease immediately (without
any action by any party hereto) and shall no longer be effective as to any
amounts thereafter payable under this Agreement upon the occurrence of a Change
of Control Transaction with respect to such HMO Subsidiary.

HMO Subsidiary hereunder shall be several and not joint, and each HMO Subsidiary
shall be liable solely for its own obligations hereunder.

      Commencing on January 1, 2002 and continuing for twelve (12) consecutive
months thereafter, within five (5) days of APS' receipt of each monthly
Capitation Payment, APS shall pay to CFIC One Hundred Sixty-six Thousand, Six
Hundred Sixty-six and 67/100 dollars ($166,666.67) (which monthly payments will
total Two Million dollars ($2,000,000).

      9.3.  ANNUAL ADJUSTMENTS FOR INFLATION.

      Beginning on January 1, 2004, and annually thereafter on the first (1st)

      9.4   FINANCIAL LIABILITY FOR MHSA SERVICES.

            APS acknowledges that it is financially liable for MHSA Services
provided to Capitated Members and any other Members for which it is financially
responsible under this Agreement. However, if any HMO Subsidiary shall fail to
pay APS any monthly Capitation Payment required pursuant to SECTION 9.1.1. by
the last day of any month, upon five (5) days prior written notice given to CHC
and such HMO Subsidiary, APS shall cease to have any financial responsibility
for any MHSA Services provided to Capitated Members of such HMO Subsidiary
thereafter, until all such Capitation Payments for which any such notice has
been given and all other Capitation Payments then due hereunder from such HMO
Subsidiary shall have been paid to APS, it being understood that in no event may
APS withhold any services prior to the effective date of any termination of this
Agreement. In the event an Affiliated Payor does not pay an HMO Subsidiary
amounts due under the terms of its agreement with the HMO Subsidiary, the HMO
Subsidiary shall nevertheless remain liable to APS pursuant to the terms of this
Agreement.

      9.5.  PAYMENT IN FULL.

            APS shall accept and shall require MHSA Providers to accept as
payment in full for MHSA Services provided to Members such amounts as are paid
pursuant to the agreements with the MI-ISA Providers. MI-ISA Providers may

covered as provided under the Member's Benefit Contract.

      9.6.  MEMBER PROTECTION PROVISION.

            9.6.1 This Section applies when any applicable Benefit Contract,
statute or regulation requires that the Member be held harmless from any and all
costs which are the legal obligation of an HMO Subsidiary or the Affiliated
Payor.

            9.6.2 In no event, including, but not limited to, non-payment for
MHSA Services provided to Members; insolvency of an HMO Subsidiary, the

      9.7   COORDINATION OF BENEFITS AND SUBROGATION FOR CAPITALIZED MEMBERS.

            Each HMO Subsidiary shall not seek coordination of benefits or
subrogation for MHSA Services provided to Capitated Members. APS shall seek
coordination of benefits or subrogation for MHSA Services provided to Members
and APS shall (i) retain all amounts APS recovers for MHSA Services provided to
Capitated Member through the coordination of benefits or subrogation and (ii)
promptly pay over to the applicable HMO Subsidiary all amounts APS recovers for
MHSA Services provided to Members other than Capitated Members through the

illness that requires MHSA Services and non-MHSA Services, APS, each HMO
Subsidiary and CHC shall cooperate with each other in subrogation and
coordination of benefits actions.

      9.8.  CAPITATION RATES FOR LARGE ACCOUNTS.

            Notwithstanding the Capitation Rates set forth in ATTACHMENTS B1-11
or anything to the contrary contained in this Agreement, new accounts that are
contracted by or proposed to be contracted by an HMO Subsidiary after the
Effective Date and that have 1,000 or more employees (not including dependents)
shall, at the option of the HMO Subsidiary, either be included in this Agreement
at the Capitation Rates set forth on ATTACHMENT B or be treated as if such
accounts were a CHC Acquired Person under SECTION 10.5.2.

      9.9.  ACTUARIAL SUPPORT FOR CAPITATION RATES.

            APS shall provide actuarial support for the Capitation Rates as

10.   EXCLUSIVITY, NON-COMPETITION

      10.1. EXCLUSIVE ENGAGEMENT.

            10.1.1 EXCLUSIVITY. Except as provided in SECTION 10.1.2, CHC and
each HMO Subsidiary hereby engage APS during the term of this Agreement as their
exclusive provider of the managed behavioral health care services contemplated
in this Agreement with respect to the Covered Products. Except as otherwise
provided herein, none of CHC or the HMO Subsidiaries, shall engage or otherwise
contract with any party other than APS to perform any such services during the
term of this Agreement.

            10.1.2 EXCEPTIONS TO EXCLUSIVITY AND NON-COMPETITION. The
exclusivity requirements in this SECTION 10.1 and the non-competition provisions
in SECTION 10.2 shall not apply to the following:

                  (a) The performance by the HMO Subsidiaries of their
      obligations under existing third party service agreements that have been
      disclosed to APSH in writing prior to the Commencement Date.

                                       26
<PAGE>

                  (b) Any mental health and substance abuse service agreements
      to which any CHC Acquired Person is a party as of the time of becoming a
      CHC Acquired Person.

                  (c) (i) Subject to CHC's compliance with clause (ii) below,
      any Competing Services (as defined in SECTION 10.2) provided directly or
      indirectly by a CHC Acquired Person as long as such Competing Services are
      provided primarily through or for the benefit of such CFIC Acquired Person
      or its affiliates as part of their managed care products and not as
      stand-alone carve out behavioral health care products offered
      independently.

                        ii) (A) If a CHC Acquired Person, as of the time of
      becoming a CHC Acquired Person, provides any Competing Services (other
      than those permitted under clause (i) above), CHC shall, and shall cause
      its subsidiaries to, comply with the provisions of this clause (ii).

                              (B) CHC and APSH shall negotiate in good faith and
      in a commercially reasonable manner the amount in cash (the "CASH PURCHASE
      PRICE") a willing third party purchaser that is similarly situated to APSH
      would pay for the business segment of such CHC Acquired Person that
      provides the Competing Services (the "Competing Business Segment"). If,
      after 30 days of such negotiations, CHC and APSH are unable to agree upon
      a Cash Purchase Price for the Competing Business Segment, CHC and APSH
      shall engage a Business Valuer to determine in a commercially reasonable
      manner the Cash Purchase Price in respect of such Competing Business
      Segment. The Business Valuer shall deliver its determination of the Cash
      Purchase Price for the Competing Business Segment to CHC and APSH in
      writing no later than 60 days following its appointment as Business
      Valuer. The costs and expenses associated with such Business Valuer shall
      be borne equally between CHC and APSH.

                              (C) Once the Cash Purchase Price for the Competing
      Business Segment has been established pursuant to clause (B) above, CHC,
      within 10 days following such date, shall deliver a written notice (the
      "COMPETING BUSINESS SEGMENT NOTICE") to APSH offering to sell the
      Competing Business Segment to APSFI for the Cash Purchase Price and on
      other customary terms and conditions. For a period of 30 days following
      receipt of the Competing Business Segment Notice, APSH shall have the
      exclusive and nontransferable right to purchase, or to cause any
      wholly-owned direct or indirect subsidiary to purchase, the Competing
      Business Segment from CHC on the terms and conditions specified in the
      Competing Business Segment Notice. If APSH elects to purchase (directly or
      indirectly) the Competing Business Segment on such terms and conditions,
      it shall so notify CHC in writing within such 30-day period, and APSFI and
      CHC shall exercise commercially reasonable efforts to consummate such
      purchase as soon as practicable thereafter. If APSH declines to elect to
      purchase the Competing Business Segment within such 30-day period, CFIC,
      or the subsidiary of CHC which acquired the CHC Acquired Person, may
      retain its interest in and operate the Competing

                                       27
<PAGE>

      Business Segment without any further obligation to APSH or any other
      person hereunder with respect thereto.

            (d) A Subcapitation Arrangement permitted under SECTION 4.2.3.

            (e) The provision of or arranging for the provision of managed
      health care services by or for an HMO Subsidiary or Operating Unit in
      respect of a New Line of Business if such services are not incorporated
      into this Agreement.

            (f) The provision of or arranging for the provision of managed
      health care services by or for a CHC Acquired Person that does not become
      a party to this Agreement.

            10.1.3 NEW LINE OF BUSINESS. APS recognizes that when an HMO
Subsidiary offers a New Line of Business, price and quality of the MI-ISA
Services to be provided in connection therewith must be competitive.
Accordingly, in the event that any HMO Subsidiary chooses during the term of
this Agreement to offer a New Line of Business to its customers, including in
the event such HMO Subsidiary responds to Requests for Proposals ("RFP") for new
Governmental Programs, such HMO Subsidiary shall offer APS the first opportunity
to provide such MHSA Services. APS shall have 10 business days (or, in the case
of an RFP, such shorter period of time as the applicable HMO Subsidiary shall
prescribe to allow it to timely respond to such RFP) of receiving notice and the
relevant information regarding the New Line of Business to make a proposal as to
the terms on which it will provide such MHSA Services. If such proposal is
reasonably acceptable to the applicable HMO Subsidiary, the Products which
comprise such New Line of Business shall become Covered Products hereunder and
APS shall provide such MHSA Services in accordance with the terms of such
proposal; provided that if the proposal is made in connection with an HMO
Subsidiary's response to an RFP, such proposal shall be incorporated into such
response. If APS's proposal with respect to such MHSA Services is not reasonably
acceptable to such HMO Subsidiary, the HMO Subsidiary may solicit proposals from
other national managed behavioral health companies to provide such services,
provided that such proposals must be at a level of service quality comparable to
APS's proposal. Before accepting any such proposal from a third party managed
behavioral health company, the HMO Subsidiary shall offer APS an opportunity to
match such proposal. If APS notifies the HMO Subsidiary in writing within 5
business days of receiving notice and relevant information as to such proposal
(or within such earlier deadline as required to allow such HMO Subsidiary to
timely respond to an RFP) that APS will match the proposal, (a) the Products
which comprise such New Line of Business shall become Covered Products hereunder
and APS shall provide such MHSA Services in accordance with the terms of such
proposal (provided that if the proposal is made in connection with an HMO
Subsidiary's response to an RFP, such proposal shall be incorporated into such
response) and (b) notwithstanding anything to the contrary contained in SECTION
16.3.1, CHC shall not be entitled to any Commission based on such New Company
Business. If APS does not so match the proposal, (i) the HMO Subsidiary may
accept such proposal from such third party managed behavioral health company and
(ii) neither CHC nor the applicable HMO Subsidiary shall have any further
obligation to APS under this Agreement with respect to such New Line of
Business.

                                       28
<PAGE>

      10.2. NON-COMPETITION.

            Except as provided in SECTION 10.1.2, without APS's prior written
consent, CHC and each HMO Subsidiary agree that neither they nor their
respective subsidiaries shall, directly or indirectly (whether in conjunction
with a third party or otherwise), during the term of this Agreement provide any
managed behavioral health care services within the Service Area in a manner that
competes directly with the managed behavioral health care and administrative
services APS offers or performs, including, without limitation, the managed
health care services provided under this Agreement ("COMPETING SERVICES").

      10.3. NO SOLICITATION OF APS EMPLOYEES.

            During the term of this Agreement and for a period of one year
following the termination of this Agreement, none of the HMO Subsidiaries or CHC
shall, without the prior consent of APS, directly or indirectly, solicit, employ
or engage any employee of APS. The foregoing obligations shall not apply to
employees who are terminated or given notice thereof by APS or who terminate
their employment for cause.

      10.4. NO SOLICITATION OF CHC OR HMO SUBSIDIARY EMPLOYEES.

            During the term of this Agreement and for a period of one year
following the termination of this Agreement, neither APSH or APS shall, without
the prior consent of CHC or an HMO Subsidiary, as applicable, directly or
indirectly solicit, employ or engage any employee of CHC or an HMO Subsidiary.
The foregoing obligations shall not apply to employees of CHC or any HMO
Subsidiary who are terminated or given notice thereof by CHC or such HMO
Subsidiary or who terminate their employment for cause.

      10.5. HMO SUBSIDIARIES.

            10.5.1. CURRENT HMO SUBSIDIARIES. The Current HMO Subsidiaries shall
be bound by this Agreement as of the Effective Date and this Agreement shall be
binding upon any successor of an HMO Subsidiary in a Change of Control
Transaction unless terminated pursuant to SECTION 15.2.5(B).

            10.5.2. CHC ACQUIRED PERSONS. If CHC or any direct or indirect
subsidiary thereof, including any HMO Subsidiary, acquires any CHC Acquired
Person during the term of this Agreement (i) the acquiror or such CHC Acquired
Person may honor such CHC Acquired Person's existing managed behavioral health
contracts for the duration of the terms thereof and (ii) upon consummation of
the acquisition or, if such CHC Acquired Person has such an existing contract,
upon termination thereof, the acquiror shall offer APS the first opportunity to
provide MI-ISA Services in respect of such CHC Acquired Person. APS shall have
10 business days of receiving notice and the relevant information regarding the
CHC Acquired Business to make a proposal as to the terms on which it will
provide such MI-ISA Services. If such proposal is reasonably acceptable to the
acquiror, such acquiror shall (if not already a party hereto) become a party to
this Agreement, and APS shall provide such MHSA Services with respect to such
CHC Acquired Person in accordance with the terms of such proposal. If APS's
proposal with respect

                                       29
<PAGE>

to such MHSA Services is not reasonably acceptable to such acquiror, such
acquiror may solicit and accept proposals from other national managed behavioral
health companies to provide such services, provided that such proposal must be
at a level of service quality comparable to APS's proposal. Before accepting any
such proposal from a third party managed behavioral health company, such
acquiror shall offer APS an opportunity to match such proposal. If APS notifies
such acquiror in writing within 5 business days of receiving notice and relevant
information as to such proposal that APS will match the proposal, (a) such
acquiror shall (if not already a party hereto) become a party to this Agreement,
and APS shall provide such MHSA Services with respect to such CHC Acquired
Person in accordance with the terms of such proposal and (b) notwithstanding
anything to the contrary contained in SECTION 16.3.1, CHC shall not be entitled
to any Commission based the New Company Business consisting of such MHSA
Services. If APS does not so match the proposal, (i) the acquiror may accept
such proposal from such third party managed behavioral health company and (ii)
neither CHC nor such acquiror shall have any further obligation to APS under
this Agreement with respect to such CHC Acquired Business.

      10.6. OPERATION OF BUSINESS.

            Nothing contained in this Agreement shall be deemed to (1) require
any HMO Subsidiary to enter into any Benefit Contract with any Enrolling Unit or
to renew any such Benefit Contract, (ii) preclude any HMO Subsidiary from
terminating any such Benefit Contract, (iii) require any HMO Subsidiary to
maintain any minimum amount of Members at any time, (iv) prevent any HMO

            Subject to SECTION 15.3, in the event a dispute between APS and an
HMO Subsidiary or CHC arises out of or is related to this Agreement, APS and the
applicable HMO Subsidiary or CHC, as the case may be, shall meet and negotiate
in good faith to attempt to resolve the dispute. In the event the dispute is not
resolved within 30 days of the date one of the parties sent written notice of
the dispute to the other party, and if one of the parties wishes to pursue the
dispute, it shall be submitted to binding arbitration in accordance with the
rules of the American Arbitration Association. In no event may arbitration be
initiated more than one year following the sending of written notice of the
dispute. Any arbitration proceeding under this Agreement shall be conducted in
the State of Maryland. The arbitrators shall have no authority to award any
punitive or exemplary damages or to vary or ignore the terms of this Agreement
and shall be bound by controlling law.

      14.2. RENEGOTIATION OF THIS AGREEMENT DUE TO A SIGNIFICANT CHANGE OF
CIRCUMSTANCES.

            In the event a significant change of circumstances occurs during the
term of this Agreement, which presents a fundamental departure from the
assumptions and the intent of the parties in entering into this Agreement, and,
as a result thereof, the Capitation Rates for the services to be provided by APS
thereafter no longer reflect prevailing rates in the managed behavioral health
market for such services, then the parties shall, upon the request of CHC or
APS, adjust such Capitation Rates in accordance with the process set forth in
SECTION 9.3 hereof. A significant change of circumstances shall include, but is
not limited to, (a) a significant change in law or an order for compliance
issued by a government authority having competent jurisdiction; and/or (b)
significant changes in NCQA standards applicable to managed behavioral health
organizations or in prevailing industry standards with respect to NCQA
compliance. Any

                                       34
<PAGE>

adjustment to the Capitation Rates pursuant to this SECTION 14.2 shall be
retroactive to the first day of the month following the month in which the
request to adjust the Capitation Rates was made.

      14.3. RENEGOTIATION PROCEDURE.

            If SECTION 3.4 provides for renegotiation of this Agreement pursuant
to this SECTION 14.3, the parties shall engage in good faith negotiations with
the intent and goal of reaching a consensus which will preserve each party's
anticipated benefit and respective rights and obligations under this Agreement
and avoid default of this Agreement. Failure to agree upon renegotiated amounts
pursuant to SECTION 3.4 within 75 days after request for renegotiation shall be
submitted to arbitration pursuant to SECTION 14.1. When an event occurs which
allows for renegotiation of the amounts to be paid to APS under this Agreement,
the HMO Subsidiaries shall pay the amounts specified in SECTION 9.1 until final
resolution of the dispute. Any adjustments to the amounts paid to APS that are
subsequently agreed to by the parties shall be retroactive to the effective date
of the event which allowed for such renegotiation.

            15.2.3 PERFORMANCE BELOW TERMINATION STANDARDS

            (a) TERMINATION STANDARDS. By any HMO Subsidiary (as to such HMO
      Subsidiary or any of its Operating Units) at any time if (i) APS fails,
      with respect to such HMO Subsidiary or any such Operating Unit, to perform

            (b) HMO LICENSURE. By any HMO Subsidiary (as to such HMO Subsidiary
      or any of its Operating Units) if APS fails to perform at a level above

            15.2.6 TERMINATION FOR PARTIAL CAUSE.

            Any HMO Subsidiary shall have the right to terminate this Agreement
      with respect to that HMO Subsidiary pursuant to the terms set forth below
      by providing thirty (30) days written notice and paying the associated
      partial CBA payment as set forth in Section 15.3 hereof:

            (a) During any consecutive twelve (12) month period, more than
      twenty percent (20%) of any HMO Subsidiary's Members are required to seek
      alternative MHSA Providers from an Out-of-Network Provider due to MHSA
      Providers terminating their Participation Agreements with APS; and APS is
      unable to provide an alternative network of MHSA Providers which
      reasonably satisfies the majority of the dislocated Members. Such
      alternative network of MHSA Providers must be provided by APS within forty
      five (45) days of APS' receipt of written notice from the applicable HMO
      Subsidiary of the 20% threshold referenced above being exceeded. Further,
      any Members who have out-of-network benefits will not be counted for
      purposes of the above-referenced 20% threshold; or

            (b) There are pervasive documented MHSA Provider or Member
      complaints to regulators or Governmental Bodies which establish a
      significant risk to that HMO Subsidiary and thus results in any one of the
      following:

            (i) Suspension or revocation of the HMO Subsidiary's license or
            certificate of authority; or

            (ii) A sanction, fine or public censure of the HMO Subsidiary by a
            Governmental Body due to APS' failure to perform its obligations
            under this Agreement and for which such failure to perform is
            significant. In order to terminate the contract based on this
            Section 15.2(b)(ii), the HMO Subsidiary shall have provided APS with
            45 days prior written notice of the failure to perform and APS shall
            have failed to cure its nonperformance within such period. Payment
            by any HMO Subsidiary of a fine or sanction equal to or exceeding
            $50,000 due to APS' actions shall be evidence of a significant
            failure to perform by APS; or

            (iii) The limitation by a Governmental Body of a HMO Subsidiary's
            ability to enroll Members; or

            (iv) Legal action is instituted in state or federal court by a
            Governmental Body against a HMO Subsidiary seeking legal, equitable
            or statutory remedies based upon APS' performance or nonperformance
            of its obligations hereunder; or

                                       37
<PAGE>

            (v) In a legal action instituted in state or federal court by a
            Governmental Body against a HMO Subsidiary based upon APS'
            performance or nonperformance its obligations hereunder, a final
            judgment is entered against a health plan awarding legal, equitable
            or statutory damages. Notwithstanding the foregoing, a HMO
            Subsidiary shall notify APS in writing within 10 days of that HMO
            Subsidiary's receipt of notice that a legal action has been
            instituted and shall provide APS with the opportunity to negotiate a
            settlement of the action to avoid the entering of a final judgment.

            15.2.7 SCOPE OF TERMINATION. APS's termination of this Agreement
pursuant to SECTION 15.2.2 as to any HMO Subsidiary shall be effective only as
to that HMO Subsidiary and its constituent Operating Unit, if any, and its
termination of this Agreement pursuant to SECTION 15.2.2 as to any Operating
Unit shall be effective only as to that Operating Unit, and, in either such
case, this Agreement shall remain in effect as to the remaining parties. Any HMO
Subsidiary's termination of this Agreement pursuant to SECTION 15.2.1, 15.2.3.
15.2.4 OR 15.2.5(B) shall be effective only as to that HMO Subsidiary and its
constituent Operating Units, if any, and this Agreement shall remain in full
force and effect as to the remaining HMO Subsidiaries and Operating Units.

            15.2.8. PAYMENT OF CAPITATED BENEFICIARY ADJUSTMENT. Notwithstanding
anything to the contrary set forth in this Agreement, no termination pursuant so
this SECTION 15.2 shall be effective unless and until the payment of the
Capitated Beneficiary Adjustment, if any, as set forth in SECTION 15.3 below,
has been made to APSH; provided, however, that in the event CFIC or any HMO
Subsidiary seeks to terminate this Agreement pursuant to this SECTION 15.2 and,
in connection therewith, pays the Capitated Beneficiary Adjustment that CHC or
such HMO Subsidiary believes in good faith is required by such SECTION 15.3 in
respect of such termination, such termination shall be deemed effective upon
such payment, regardless of whether APS or APSH disputes the amount of such
payment, and the sole right of CHC and APSH shall be to seek arbitration
pursuant to SECTION 15.4 regarding the amount of such payment.

      15.3. CAPITATED BENEFICIARY ADJUSTMENT.

            15.3.1 CAPITATED BENEFICIARY ADJUSTMENT Subject to Sections 15.3.2,
15.3.3 and 15.3.4 hereof:

      15.2.6(b)(v) hereof, no CBA payment shall be due or payable by CHC with
      respect to such termination.

            (b) If this Agreement is terminated pursuant to SECTION 15.2.4 or

      names of the Original HMO Subsidiaries that are parties to this Agreement
      immediately prior to such termination.

            (c) If this Agreement is terminated pursuant to SECTION 15.2.5(a) or
      15.2.5(c) hereof, CHC shall pay APSH 100% of the CBA with respect to the
      number of Capitated

                                       38
<PAGE>

      Members set forth on ATTACHMENT K hereto opposite the names of the
      Original HMO Subsidiaries that are parties to this Agreement immediately
      prior to such termination.

            (d) If this Agreement is terminated with respect to any Original HMO
      Subsidiary or Original Operating Unit pursuant to SECTION 15.2.5(b)
      hereof, CHC shall pay APSH 100% of the CBA with respect to the number of
      Capitated Members set forth on ATTACHMENT K hereto opposite the name of
      such Original HMO Subsidiary or Original Operating Unit; provided,
      however, that if, contemporaneously with any such. termination (i) the
      acquiror offers to enter into (or to cause such Original HMO Subsidiary to
      enter into) a service agreement with APSH or APS with respect to the
      Capitated Members of such Original HMO Subsidiary or Original Operating
      Unit as to whom this Agreement is then being terminated, on terms
      substantially identical to those contained in this Agreement relating to
      such Capitated Members, then no CRA shall be payable by CHC with respect
      to such termination or (ii) the acquiror or such Original HMO Subsidiary
      enters into a service agreement (the "NEW SERVICE AGREEMENT") with APSH or
      APS with respect to any or all of the Capitated Members of such Original
      HMO Subsidiary or Original Operating Unit as to whom this Agreement is
      then being terminated and such New Service Agreement involves services to
      be provided by APSH or APS comparable to those services provided by APS
      under this Agreement in respect of such Capitated Members, then (x) if the
      monthly capitation payments payable under the New Service Agreement with
      respect to such Capitated Members (the "NEW CAPITATION PAYMENTS") equal or
      exceed the monthly Capitation Payments payable under this Agreement with
      respect to such Capitated Members (the "OLD CAPITATION PAYMENTS"), no CBA
      shall be due or payable by CHC with respect to such termination and (y) if
      the New Capitation Payments are less than the Old Capitation Payments, CHC
      shall pay APSH an amount equal to the lesser of (A) the CBA payment
      provided for above in this clause (d) with respect to such termination,
      (B) if the number of such Capitated Members covered by the New Service
      Agreement is equal to or less than the number of Capitated Members set
      forth on ATTACHMENT K hereto opposite the name of such Original HMO
      Subsidiary or Original Operating Unit, the excess of the then present
      value (calculated using a interest rate of 10% per annum compounded
      quarterly) of the aggregate Capitation Payments that would have been
      payable under this Agreement over its remaining term with respect to such
      Capitated Members over the then present value (calculated in the same
      manner) of the aggregate capitation payments payable under the New Service
      Agreement over the same period with respect to such Capitated Members
      (such excess being hereinafter referred to as the "EXCESS PRESENT VALUE")
      and (C) if the number of such Capitated Members covered by the New Service
      Agreement is more than the number of Capitated Members set forth on
      ATTACHMENT K hereto opposite the name of such Original HMO Subsidiary or
      Original Operating Unit, an amount equal to the product of the Excess
      Present Value multiplied by a fraction, the numerator of which is equal to
      the number of Capitated Members so set forth on ATTACHMENT K hereto and
      the denominator of which is equal to the number of Capitated Members so
      covered by the New Service Agreement.

            (e) If this Agreement is terminated pursuant to SECTION 15.2.6(a)
      hereof, CHC shall pay APSH 62.5% of the CBA with respect to the number of
      Capitated Members set

                                       39
<PAGE>

      forth on ATTACHMENT K hereto opposite the name of such Original HMO
      Subsidiary or Original Operating Unit.

            (f) If (i) this Agreement is terminated with respect to any or all
      of the Capitated Members of any Original HMO Subsidiary pursuant to
      SECTION 4.2.3 hereof; (ii) such Original HMO Subsidiary does not enter
      into a Subcapitation Arrangement in connection therewith in which either
      APS or APSH or any Affiliate of either thereof is engaged to provide or
      administer behavioral health services, and (iii) the number of Capitated
      Members of such Original HMO Subsidiary covered by this Agreement
      immediately after giving effect to such termination (the "REMAINING
      CAPITATED MEMBERS") is less than the number of Capitated Members set forth
      on ATTACHMENT K hereto opposite the name of such Original HMO Subsidiary,
      then CHC shall pay APSH 100% of the CBA with respect to a portion of the
      number of Capitated Members set forth on ATTACHMENT K hereto opposite the
      name of such Original HMO Subsidiary equal to the product of such number
      of Capitated Members multiplied by a fraction, the numerator of which is
      equal to the lesser of (A) the excess of (x) the number of Capitated
      Members set forth on ATTACHMENT K hereto opposite the name of such
      Original HMO Subsidiary over (y) the number of Remaining Capitated Members
      and (B) the number of Capitated Members of such Original HMO Subsidiary as
      to whom this Agreement is then being terminated and the denominator of
      which is the number of Capitated Members set forth on ATTACHMENT K hereto
      opposite the name of such Original HMO Subsidiary.

            (g) If this Agreement is terminated with respect to any Original HMO
      Subsidiary or Original Operating Unit pursuant to SECTION 15.2.2 hereof,
      CHC shall pay APSH 125% of the CBA with respect to the number of Capitated
      Members set forth on ATTACHMENT K hereto opposite the name of such
      Original HMO Subsidiary or Original Operating Unit.

            (h) If this Agreement is terminated pursuant to SECTION
      15.2.6(b)(iv) hereof, CFIC shall pay APSH 75% of the CBA with respect to
      the number of Capitated Members set forth on ATTACHMENT K hereto opposite
      the name of such Original HMO Subsidiary or Original Operating Unit.

            (i) If this Agreement is terminated pursuant to SECTION
      15.2.6(b)(iii) hereof, CHC shall pay APSH 25% of the CBA with respect to
      the number of Capitated Members set forth on ATTACHMENT K hereto opposite
      the name of such Original HMO Subsidiary or Original Operating Unit.

            (j) Except as specifically provided herein, in the event of a
      termination of this Agreement, neither CHC nor any HMO Subsidiary or
      Operating Unit shall have any obligation or responsibility to pay any
      Capitated Beneficiary Adjustment.

            15.3.2 OFFSET FOR NEW ENROLLMENT. Notwithstanding anything to the
contrary set forth in this Agreement, if (a) this Agreement is terminated with
respect to any Original HMO Subsidiary (or part thereof) or Original Operating
Unit pursuant to SECTION 15.2.5(b) OR SECTION 4.2.3 hereof and any amounts would
(but for this SECTION 15.3.2) be payable or have been paid pursuant to SECTION
15.3.1(d) or (f) hereof in respect of such termination and (b) any

                                       40
<PAGE>

New Company Business (as defined in Section 16.3.1 hereof) within the meaning of
clause (X) of the definition thereof has been or is acquired by CHC or any HMO
Subsidiary within one year before or after such termination, then any Capitated
Beneficiary Adjustment that was paid, or THAT WOULD OTHERWISE BE PAYABLE,
PURSUANT TO SECTION 15.3.1(d) OR (f) hereof (the "TERMINATION PAYMENT") in
respect of such termination shall be repaid by APSH to CHC or, to the extent not
theretofore paid, shall be reduced, in each case in an amount (not to exceed the
amount of the Termination Payment) equal to the product of the Termination
Payment multiplied by a fraction, the numerator of which shall be the number of
Capitated Members added to this Agreement as a result of such New Company
Business who have not yet been deemed to be Capitated Members included on
ATTACHMENT K hereto (the "NEW CAPITATED MEMBERS") and the denominator of which
shall be (i) in the case of a termination under SECTION 15.2.5(b) of this
Agreement, the number of Capitated Members set forth on ATTACHMENT K hereto
opposite the name of such Original HMO Subsidiary or Original Operating Unit and
(ii) in the case of a termination under SECTION 4.2.3 of this Agreement, the
number of Capitated Members as to whom the CBA payment was or (but for this
SECTION 15.3.2) would be made pursuant to SECTION 15.3.1(f) hereof; provided
that if any such New Company Business is not acquired until more than ninety
(90) days after the date of any such termination of this Agreement, the amount
to be repaid by APSH to CHC shall be reduced by an amount equal to 10% of the
Capitation Payments that would have been payable under this Agreement (had the
termination not taken place) with respect to a number of Capitated Members equal
to the number of Capitated Members as to whom the CBA payment was then made
pursuant to SECTION 15.3.1(f) in respect of the period commencing on the ninety
first (1st) day following such termination and ending on the date of such
acquisition of New Company Business. If any CBA payment is reduced or repaid
pursuant to this SECTION 15.3.2 and (x) the New Company Business was acquired by
any Original HMO Subsidiary, the number of Capitated Members set forth on
ATTACHMENT K hereto opposite the name of such Original HMO Subsidiary shall be
increased by an amount equal to the number of New Capitated Members applicable
to such reduction or repayment and (y) the New Company Business was acquired by
a person or entity other than an Original HMO Subsidiary, such person or entity
shall be deemed to be an Original HMO Subsidiary having a number of Capitated
Members equal to the number of New Capitated Members applicable to such
reduction or repayment. New Capitated Members used to offset the Capitated
Beneficiary Adjustment as contemplated hereunder shall not constitute New
Company Business with respect to which APSH is required to pay a Commission
pursuant to SECTION 16.3.1 of this Agreement and in the event such a Commission
was previously paid, CHC shall return such Commission. Any repayment of CBA by
APSH to CHC required pursuant to this SECTION 15.3.2 shall be made within ten
(10) days following the acquisition of the New Company Business giving rise to
such repayment. Notwithstanding anything to the contrary contained herein, in
the event that the ASO Members (as defined in this Agreement) of Coventry Health
Care of the Carolinas, Inc. ("CHC-CAROLINA") become Capitated Members within one
year before or after a Termination Payment was paid or would otherwise be
payable, then at CHC's option, such Capitated Members shall be deemed to be New
Capitated Members, in which case (A) the amount by which such Termination
Payment (the "CHC-CAROLINA TERMINATION PAYMENT") would otherwise be repaid or
reduced pursuant to this SECTION 15.3.2, shall itself be reduced proportionately
to reflect the difference between ASO Fees that had been payable for the ASO
Members of CHC-Carolina immediately prior to their becoming Capitated Members
and the Capitation Rate payable for the Capitated Members of CHC-Carolina
immediately thereafter, and (B) in the event any CBA

                                       41
<PAGE>

payment ever becomes payable for any reason pursuant to SECTION 15.3 in respect
of such Capitated Members of CHC-Carolina, the amount of such CBA payment shall
be reduced to reflect the fact that the CHC-Carolina Termination Payment was
reduced as provided herein.

            15.3.3 EFFECT OF CERTAIN TERMINATIONS Notwithstanding anything to
the contrary set forth in this Agreement (i) if this Agreement is terminated as
to any Original HMO Subsidiary, no separate payment shall be required under
SECTION 15.3.1 hereof with respect to any Original Operating Units that are part
of such Original HMO Subsidiary, (ii) upon any termination of this Agreement as
to less than all of the Capitated Members of any Original HMO Subsidiary or
Original Operating Unit (including, without limitation, a termination pursuant
to SECTION 4.2.3 hereof), the number of Capitated Members set forth on
ATTACHMENT K hereto opposite the name of such Original HMO Subsidiary or
Original Operating Unit shall be appropriately reduced to reflect the number of
such Capitated Members with respect to whom this Agreement is then being
terminated (it being understood that if this Agreement is terminated as to all
of the Capitated Members of any Original Operating Unit but not as to all of the
remaining Capitated Members of the Original HMO Subsidiary of which such
Original Operating Unit is a part, the number of Capitated Members set forth on
ATTACHMENT K hereto opposite the name of such HMO Subsidiary shall be reduced by
the number of Capitated Members set forth on ATTACHMENT K hereto opposite the
name of such Original Operating Unit), (iii) upon termination of this Agreement
as to any Original HMO Subsidiary or Original Operating Unit, such Original HMO
Subsidiary or Original Operating Unit, as applicable, shall cease to be an
Original HMO Subsidiary or Original Operating Unit for any purpose and (iv)
following any Change of Control Transaction with respect to any Original HMO
Subsidiary or Original Operating Unit, such Original HMO Subsidiary or Original
Operating Unit, as applicable, shall cease to be an Original HMO Subsidiary or
Original Operating Unit for any purpose.

            15.3.4 PAYMENT OF CAPITATED BENEFICIARY ADJUSTMENT PAYMENT OF ANY
Capitated Beneficiary Adjustment required under SECTION 15.3.1 hereof shall be
made on and as of the effective date of the applicable termination of this
Agreement in a combination of cash and shares of APSH Common Stock as provided
in ATTACHMENT L hereto; provided, however, that in no event will CHC ever be
required in the aggregate to deliver to APSFI more than 2,705,182 shares of APSH
Common Stock (subject to appropriate adjustment in the event of any stock split,
stock dividend or other subdivision or combination of the outstanding shares of
APSH Common Stock). For purposes of calculating the value of APSH Common Stock
to be delivered by CHC to APSH as part of the Capitated Beneficiary Adjustment,
the following provisions shall apply:

            (i) if a Current Market Price exists with respect to the APSH Common
      Stock for each trading thy in the period beginning on the date that is 30
      days prior to the date on which CHC first receives notice of the
      applicable termination and ending on the date that is 20 days prior to
      such date (the "CALCULATION PERIOD"), then each share of such APSH Common
      Stock shall be valued for purposes of such delivery at the average Current
      Market Price during such Calculation Period; and

            (ii) if clause (i) does not apply with respect to a particular
      delivery of APSH Common Stock, each share of such APSH Common Stock shall
      be valued by a business

                                       42
<PAGE>

      Valuer at its fair market value as of the date immediately prior to the
      date of the applicable termination (which valuation shall, other than in
      the case of a termination pursuant to SECTION 15.2.1 or 15.2.5(A) of this
      Agreement, assume such termination shall not occur and that this Agreement
      shall otherwise remain in full force and effect until the expiration of
      its term).

      If CHC shall have sold, transferred or otherwise disposed of any shares of
APSH Common Stock (the "TRANSFERRED SHARES") in lieu of delivering such
Transferred Shares pursuant to the provisions of ATTACHMENT L hereto, CHC may
deliver to APSH cash in an amount equal to $1.44 per share (subject to
appropriate adjustment in the event of any stock split, stock dividend or other
subdivision or combination of the outstanding shares of APSH Common Stock) of
such Transferred Shares and, upon such payments CHC shall be deemed to have
delivered such Transferred Shares to APSH for all purposes hereof.

      15.4. ARBITRATION IN CERTAIN EVENTS.

            Any disputes over whether a party is entitled to terminate this
Agreement pursuant to SECTION 15.2.1. 15.2.2 OR 15.2.3(b) shall, at any party's
request, be submitted to arbitration in accordance with SECTION 14.1 and during
the pendency of any such arbitration proceeding, this Agreement shall remain in
full force and effect, subject to the following sentence. Any disputes over
whether a party is entitled to terminate this Agreement pursuant to SECTION
15.2.3(a), 15.2.4, 15.2.5 OR 15.2.6 shall not prevent the termination of this
Agreement as otherwise specified herein, provided that the foregoing shall not
preclude a party from thereafter seeking arbitration to assess damages in
respect of a wrongful termination of this Agreement by the other party. Any
disputes as to whether the correct amount of Capitated Beneficiary Adjustment
has been paid to APSH in connection with a particular termination of this
Agreement shall not prevent the termination of this Agreement as otherwise
specified herein, provided that the foregoing shall not preclude APSH or APS
from thereafter seeking arbitration to determine whether an incorrect payment
was made.

      15.5. EFFECT OF TERMINATION.

            15.5.1 Immediately upon termination of this Agreement as to any HMO
Subsidiary, such HMO Subsidiary shall notify Members subject to this Agreement
of such termination.

            15.5.2 APS shall cooperate with an HMO Subsidiary as to which this
Agreement has been terminated or such HMO Subsidiary's new mental health and
substance abuse vendor ("Vendor") in transitioning the care and management of
Members in treatment on the date of such termination. The HMO Subsidiary shall
or shall require Vendor to take and maintain the records in APS's possession
upon such terms and conditions as are agreed to an HMO Subsidiary, Vendor and
APS, but which grant APS subsequent access to such records.

            15.5.3 With respect to MHSA Services after the effective date of
termination of this Agreement:

                                       43
<PAGE>

            a. OUTPATIENT MHSA SERVICES. APS has no obligation to provide or
            arrange for the provision of outpatient MHSA Services after the
            effective date of termination of this Agreement.

            b. INPATIENT MHSA SERVICES. In the event a Member was admitted to a
            hospital pursuant to the terms of this Agreement prior to the
            effective date of termination, APS shall continue to provide and
            arrange for the provision of inpatient MHSA Services after the
            effective date of termination until the earlier of the date of the
            Member's discharge or the date on which APS recommends discharge or
            the date on which Member's coverage ceases under a Benefit Contract,
            provided, however, that CHC shall be financially liable for the
            payment of such inpatient MBSA Services.

            15.5.4 Termination of this Agreement by CHC or any HMO Subsidiary
pursuant to SECTION 15.2.3 OR 15.2.4 shall be deemed to be a termination for
breach of this Agreement by APS. In the event of a termination of this Agreement
pursuant to SECTION 15.2.1. 15.2.3 OR 15.2.4, the terminating party shall retain
all of its respective rights and remedies in respect of any breach of this
Agreement arising prior to such termination, including, without limitation, its
right to recover damages. Notwithstanding anything to the contrary contained in
this Agreement, if at any time APS terminates this Agreement pursuant to SECTION
15.2.2 as to CHC, any HMO Subsidiary or any Operating Unit, (i) APS' s sole and
exclusive remedy in respect of such termination shall be for APSFI to receive,
as liquidated damages for such termination, the Capitated Beneficiary
Adjustment, if any, payable in respect of such termination pursuant to Section
______ hereof and (ii) neither APSH nor APS shall have any other rights or
claims against CHC or any HMO Subsidiary or Operating Unit in respect of such
termination or any breach of this Agreement giving rise thereto (other than a
breach committed in bad faith); provided, however, that this sentence shall not
prevent APS from recovering any payments due and owing under this Agreement in
respect of any period prior to the effective date of such termination.

16.   OTHER AGREEMENTS

      16.1. APSH GUARANTEE.

            APSH hereby unconditionally guarantees to CHC and the HMO
Subsidiaries the prompt payment of all amounts due hereunder from APS and the
prompt performance by APS of all of its obligations hereunder, including,
without limitation, APS's obligations to pay claims pursuant to SECTION 6.1
hereof.

      16.2. SERVICES.

      If APSH, directly or indirectly through any subsidiary or affiliate, shall
desire to provide or arrange for the provision of mental health and substance
abuse services to any person or entity other than pursuant to this Agreement, it
shall do so only in one of the following manners: (I) APSFI OR APS shall provide
or arrange FOR THE provision of such services; or (ii) a wholly owned direct or
indirect subsidiary of APSFI or APS shall provide or arrange for the provision
of such

                                       44
<PAGE>

services, provided that such subsidiary guarantees the obligations of APS
hereunder to the same extent as the APSH guarantee set forth in SECTION 16.1
pursuant to an agreement reasonably acceptable to CHC.

      16.3. COMMISSION FOR NEW BUSINESS.

            16.3.1. COMMISSION. As an incentive for CHC and its affiliates to
increase the number of Members covered under this Agreement or participating in
managed behavioral health care plans and products or Employee Assistance Plans
("EAP") administered by APS, APS shall pay CHC a commission (the "Commission")
based on New Company Business obtained during the term of this Agreement. The
Commission shall be paid in cash during the term of this Agreement on an annual
basis no later than one hundred and twenty (120) days after the end of the
calendar year to which the Commission relates. The Commission for each item of
New Company Business shall equal (A) three percent (3 %) of direct annual
revenues recognized by APS for such item for the calendar year in which such
item of New Company Business commences, (B) one and one-half percent (1.5%) of
such direct annual revenues recognized by APS in the following calendar year,
and (C) one-half percent (.5%) of such direct annual revenues recognized by APS
in the next following calendar year. The aggregate annual Commission in any year
shall equal the sum of Commissions accrued during such year with respect to
revenue recognized during such year from each item of New Company Business. For
purposes of this SECTION 16.3.1, "NEW COMPANY BUSINESS" shall mean new business
of APS arising from (X) the addition of a CHC Acquired Person that becomes a
party or subject to this Agreement or (Y) the addition of any new customer of
any affiliate of CHC (other than any HMO Subsidiary) as a new managed behavioral
health care or EAP client of APS, in each case other than (i) non-commercial new
business such as Medicare, Medicaid, or CHAMPUS business or (ii) new business
sold by CHC's Healthcare Network Sales Unit ("HNS").

            16.3.2. AGREEMENT WITH HNS. After the Commencement Date, APSH and
APS shall negotiate in good faith with CHC with respect to an agreement to be
entered into between APS and CHC pursuant to which HNS would sell EAP and
managed behavioral health care products offered or administered by APS OR BY
APSFI (directly or indirectly (other than through APS)). Such agreement would
provide, among other things, that CHC would receive compensation appropriate to
cover a portion of HNS overhead costs plus incentive compensation costs
associated with the sale of such products by HNS, which compensation would be
negotiated by the parties in good faith.

                                 MIXED SERVICES

                  MEDICAL VS PSYCH CLAIMS PAYING RESPONSIBILITY

A.    HOSPITAL

      The intent of this policy statement is to establish guidelines to help
determine responsibility for medically necessary care provided to clients. APS
Healthcare Bethesda, Inc. ("APS") will certify care when the primary treatment
is psychiatric or substance abuse and being provided by a psychiatrist. Coventry
Health Care, Inc. or its individual health plans ("CHC") will certify when the
primary treatment is medical or surgical and being provided by a
non-psychiatrist physician. Individual physician charges and charges for
diagnostics and therapeutics which the physician orders (or causes to be
ordered) will be the responsibility of the review agency to which the physician
belongs, i.e., APS when the physician is a psychiatrist; CHC when the physician
is a non-psychiatrist medical attending.

      The following guidelines will be used in utilization review and in
processing claims when the services rendered include a combination of mental
health and medical care:

1.    When a patient is admitted for the treatment of a medical problem and
      there is a concomitant psychiatric problem, the medical care rendered will
      be certified by CHC. If the patient is medically cleared and transferred
      to a psych unit, APS will assume responsibility at that point. For
      example, if a patient ingests a toxic substance in a suicide attempt and
      requires medical care in a ICU, CHC will be responsible for certifying the
      patient's care until the patient is medically cleared and transferred to a
      psych unit.

2.    When a patient is admitted with multiple diagnoses associated with
      substance abuse including both mental and medical diagnosis, CHC and APS
      will be responsible for certifying their respective portions of the
      hospitalization. For example, if a patient is primarily being admitted and
      treated for alcoholic hepatitis or pneumonia with a secondary diagnosis of
      alcohol withdrawal, the care rendered by a non-psychiatrist physician will
      be ceded by CHC. If the patient is admitted to a designated detox unit or
      psych unit for detox EVEN IF ATTENDED BY A NON-PSYCHIATRIST PHYSICIAN, APS
      will be responsible for review. If multiple diagnoses are present, the
      most critical care should be given, patient stabilized and then
      transferred to the other service with review being done by each APS and
      CHC for their respective areas.

                                      E-1
<PAGE>

3.    If a patient is admitted for a medical complaint, but the medical
      evaluation does not lead to a medical diagnosis and a psychiatric
      diagnosis is then assigned to the case, subsequent care will be certified
      by APS. When the patient is transferred to a psych unit and the primary
      care giver is a psychiatrist, APS will be responsible. For example, if a
      patient is admitted for evaluation of pain of unknown etiology, but no
      organic etiology is identified and the patient is then given a diagnosis
      of psychogenic pain, the care rendered will be reviewed by CHC. If the
      patient is then transferred to a psych unit, the care will become the
      certification responsibility of APS.

4.    Each party will make reasonable efforts to ensure that the hospitalized
      patient will receive necessary and appropriate treatment in a facility
      participating in the Network of the party certifying the primary treatment
      taking into account appropriate continuity and quality of care.

5.    If psych consults are requested by a non-psychiatrist physician, CHC will
      authorize such consultants. If med/surg consults are requested by a
      psychiatrist attending, APS will authorize such consultations. The psych
      consultation will be the financial responsibility of APS and the med/surg
      consultation will be the financial responsibility of CHC.

6.    When a patient is admitted for medical or neurologic problem, but is
      placed on a psych unit because the patient is a management problem, care
      will be certified by CHC. For example, in the case where a patient with
      organic brain syndrome housed on a psych unit for management purposes CHC
      will review regardless, as to whether the patient is attended by a
      psychiatrist or a non-psychiatrist physician.

7.    On occasion, psychiatric patient will be admitted by a psychiatrist to a
      Med/Sug unit of a rural hospital without a psych unit. Such
      hospitalization will be reviewed by APS. CHC providers are not
      credentialed to provide psych care and will only manage care medically
      until a credentialed psychiatrist is available.

B.    NEUROPSYCHOLOGICAL SCREENING VS. ASSESSMENT

      Neuropsychological SCREENING can be done by most testing psychologist and
is considered a part of standard psychological testing, which is certified by
APS. Neuropsychological ASSESSMENT is a time consuming, expensive, series of
testing procedures directed at determining special neurological deficits.
Neuropsychological assessment is one of several diagnostic procedures used to
determine organic brain disease or deficit. Neurologist are in the best position
to assess whether such testing would be useful as compared to an EMI scan, EEG,
etc. APS recommends that such testing only be approved after neuropsychological
consultation and certified by whichever agency is already reviewing the patient
care plan irrespective of whether such testing is done on an inpatient or
outpatient basis.

C.    CHRONIC PAIN

      APS' position on pain management is that there are two types of chronic
pain patients and two types of chronic pain programs developed to meet the
different needs of each type of patient.

TYPE A: TRUE CHRONIC PAIN PATIENT

The distinguishing characteristic of this group of patients is that chronic pain
is primary and substance dependence is secondary and often iatrogenic. Other
distinguishing characteristics sometimes found are listed below.

1.    Such patients usually have a relatively benign premorbid history and
      family history.

2.    Such patients often have an objectively verifiable cause for pain and
      usually a clear-cut single diagnosis.

3.    The dependence of such patients on narcotic analgesics develops when no
      other approach appears to work (or is even tried).

4.    "Chronic pain" treatment programs for these patients are generally
      directed by neurosurgeons, neurologists, physiatrist, or psychiatrists.
      Treatment approaches range from psychosurgery and cordotomy to
      transcutaneous nerve stimulation and acupuncture to biofeedback, hypnosis,
      transcendental medication/yoga, and specific exercise techniques. The
      primary responsibility for Type A patients is medical (i.e., CHC's).
      Psychiatric involvement is usually to identify and intervene with Type B
      patients (see below).

TYPE B: PSEUDO CHRONIC PAIN PATIENT

The distinguishing characteristic of this group of patients is that they are
psychiatrically-disturbed patients who are substance abusers (or potential
substance abusers) whose complaints of pain appear secondary to their
psychiatric problems. Other distinguishing characteristics are listed below.

1.    Such patients usually have a premorbid history of previous substance abuse
      and often a family history of substance abuse.

2.    Such patients often do not have pain which is objectively verifiable and
      their diagnoses are often unclear. Such patients often present multiple
      pain-related diagnoses to justify the use of narcotic analgesics.

                                      E-3
<PAGE>

3.    Such patients are usually resistant to trying other forms of pain relief,
      such as those described in the previous section, and sometimes say they
      will be "forced" into using street drugs unless their physician prescribes
      narcotic analgesics.

4.    Treatment programs (also often called "chronic pain" centers or clinics)
      are usually under the direction of psychologists or psychiatrists.
      Although some alternative pain relief treatment modalities may be
      available, the objective of such programs is generally to help the patient
      confront his/her substance abuse and addictive personality. Intensive
      group and individual counseling, urine monitoring and methadone
      maintenance are used in treatment.

      Type A patients should have access to the appropriate form of treatment
available for their chronic pain through the Plan and should be reviewed by CHC.
Type B patients are the review responsibility of APS.

D.    BIOFEEDBACK

      Biofeedback is not covered as a primary treatment modality under the
mental health benefits. However, an APS provider may use biofeedback as an
adjunctive modality (like one might use hypnosis) in the course of an otherwise
approved treatment modality in the course of treating a patient with a DSM-III
diagnosis, i.e., when biofeedback is used in the treatment of selected patients
with anxiety, panic or phobic disorders.

      Biofeedback has been demonstrated to be effective in the treatment of
conditions which are primarily medical in nature, such as migraine or tension
headache, Raynaud's disease, chronic pain, etc. Although APS endorses the use of
biofeedback in such treatment, CHC must review for medical necessity if a
nonpsychiatric physician is the prescribing physician.

E.    NON-PSYCHIATRIC PHYSICIANS TREATING DSM III R DIAGNOSES

      Not uncommonly non-psychiatric physicians will treat a patient for a DSM
III R diagnosis. Ordinarily such care will occur on an outpatient basis and
review will be the responsibility of CHC. On occasion a patient will be admitted
for a DSM III R diagnosis to a primary care unit, E.G., eating disorders,
chronic pain, substance abuse withdrawal. For example, when a pediatrician is
treating an anorexic teenager on a pediatric unit when the patient is in no
immediate medical danger, the case will be reviewed by a CHC reviewer who can
assess the limits of the pediatrician's competence in treating the primary
diagnosis of anorexia nervosa and judge the need for continued hospitalization.
Should CHC determine the need for transfer to a Child Psychiatrist, APS will
review the treatment plan and approve care.

      activity, CHC of Delaware shall give 10 days notice to APS and APS shall
      in turn notify its Affiliated Provider to cease such collection activity.
      If an Affiliated Provider fails to cease such activity during that time,
      APS will terminate its Participation Agreement with such Affiliated
      Provider specific to DelawareCare and take all other appropriate action
      consistent with the terms of this Amendment to eliminate such other
      appropriate action consistent with the terms of this Amendment to
      eliminate such collections, including requiring Affiliated Providers to
      return to Medicaid Members all sums collected. The parties agree that
      Affiliated Providers shall not maintain any action at law or equity
      against a Medicaid Member to collect any sums owed by CHC of Delaware.
      Nothing in this Amendment, however, shall be construed to prevent an
      Affiliated Provider from providing non-Medicaid Covered Services on usual
      and customary fee-for-service basis to Medicaid Members.

            Services to Medicare Members. APS further agrees that it shall
            require its MHSA Providers not to differentiate or discriminate in
            the treatment of Medicare Members on the basis of race, sex, age,
            religion, place of residence, health status or source of payment.

      2.2   Compliance

            2.2.1 APS agrees to use its best efforts to require MHSA Providers
                  to maintain such records and provide such information to HMO,
                  CMS, and the state of Florida as may be necessary to comply
                  with all rules and regulations adopted thereby. APS shall use
                  its best efforts to cause the MHSA Provider to retain such
                  records for such time as is required by appropriate
                  regulations.

            2.2.2 APS agrees to use its best efforts to require MHSA Providers
                  not to surcharge Medicare Members. A surcharge is any
                  additional fee, other than the applicable Copayments, that is
                  charged to a Medicare Member for Medicare Covered Services.

            2.2.3 APS agrees to cooperate with and be bound by, and to use its
                  best efforts to require MHSA Providers to cooperate with and
                  be bound by, all of the rules and regulations of the HMO with
                  respect to the Medicare Program, including, but not limited
                  to, HMO's quality assurance program, member grievance system,
                  utilization management program, or Medicare appeals program.

            2.2.4 APS shall use its best efforts to cause each MHSA Provider to
                  comply with the terms and conditions of this Amendment
                  applicable to the delivery of Medicare MHSA Covered Services
                  to Medicare Members.

      2.3   Collection of Charges from Medicare Members

            APS shall require MHSA Providers to collect applicable Copayments
            from Medicare Members upon the rendering of service. With the
            exception of Copayments, APS shall require MHSA Providers not to
            charge, collect, or receive payment from any Medicare Member for
            Medicare MHSA Covered Services provided pursuant to this Amendment.
            Upon discovery of collection activity, HMO shall give 10 days notice
            to APS and APS shall in turn notify the applicable

                                     G-2-3
<PAGE>

            MHSA Provider to cease such collection activity. If an MHSA Provider
            fails to cease such activity during that time, APS will terminate
            its Participation Agreement with such MHSA Provider specific to the
            Medicare Program and take all other appropriate action consistent
            with the terms of this Amendment to eliminate such collections,
            including requiring MHSA Providers to return to Medicare Members all
            sums collected. The parties agree that MHSA Providers shall not
            maintain any action at law or equity against a Medicare Member to
            collect any sums owed by HMO, including in the event of HMO's
            insolvency. Nothing in this Amendment, however, shall be construed
            to prevent an MHSA Provider from providing non-Medicare Covered
            Services on usual and customary fee-for-service basis to Medicare
            Members provided the Medicare Member has agreed in writing to be
            financially liable for such non-Covered Services prior to the
            rendering of the non-Covered Services.

      2.4   Collection of Payment from Third Party Where Medicare is not the
            Primary Payor

            Medicare is not the primary payor for Medicare MHSA Covered Services
            where the Medicare Member is entitled to benefits under a state or
            federal worker's compensation law, an automobile medical or no-fault
            insurance policy, or an employer group health plan. In such
            instances, the HMO may charge the insurance carrier, employer or
            other entity that is liable for such services or the Medicare
            Member, to the extent that the Medicare Member has received, or may
            be eligible to receive, compensation for such services. APS agrees
            to cooperate with HMO in collecting any third party payments payable
            to HMO. If Medicare is not the primary payor, collection of payment
            will be handled as a Coordination of Benefits pursuant to the
            Agreement and HMO policies.

      2.5   Required Notifications

            2.5.1 APS shall require MHSA Providers to notify APS of any action
                  to revoke, restrict, or suspend such MHSA Provider's license.

            2.5.2 APS agrees to provide CHC and HMO with a minimum of 10 days
                  advance notice in the event of termination, cancellation, or
                  reduction of the professional liability coverage required
                  pursuant to the terms of this Amendment.

            2.5.3 APS shall require MHSA Providers to immediately notify APS in
                  the event an MHSA Provider's medical staff membership and/or
                  clinical privileges are modified, suspended, or revoked,
                  regardless of whether such action occurs at a Participating
                  Provider hospital or non-Participating Provider hospital.

      2.6   Documentation

            APS shall require MHSA Providers to maintain medical records, for
            each Medicare Member, which records shall document the existence of
            any advance directive in accordance with the Patient Self
            Determination Act, as amended from time to time.

      2.7   Procedures

            APS agrees to provide policies and procedures to MHSA Providers for
            such MHSA Provider's participation in HMO's Medicare Program.
            Further, APS shall provide MHSA Providers with prior written notice
            in the event of any changes to such procedures.

      2.8   Subcontracts

            APS agrees to maintain its books, records, Participation Agreements,
            and other documentation of Medicare MHSA Covered Services rendered
            to Medicare Members at APS's principal place of business in the
            State of Maryland. Further, upon HMO's or CHC's request and within
            20 days of such request, APS agrees to provide CHC and/or HMO access
            to any Participation Agreement entered into by and between APS and
            MHSA Providers.

      2.9   Utilization Data Reports

            APS shall provide HMO with periodic reports concerning utilization
            of Medicare MHSA Covered Services and claims paid by APS for
            Medicare Members. Such reports shall be provided to CHC and HMO in a
            mutually agreeable format, and shall allow HMO to monitor the
            appropriateness of payments made and Medicare MHSA Covered Services
            received by Medicare Members.

3.    OBLIGATIONS OF HMO

      3.1   Identification Cards and Verification of Eligibility

            HMO shall provide appropriate identification cards for Medicare
            Members. The cards will assist APS and MHSA Providers in determining
            the level of Copayments to be collected from a Medicare Member, as
            well as a toll-free telephone number for verification of eligibility
            and Utilization Review requirements. HMO agrees to use its
            commercially reasonable efforts to include APS's phone number on
            identification cards for Medicare Members and to use its
            commercially reasonable efforts to include instructions for Medicare
            Members to contact APS in order to access Medicare MHSA Covered
            Services.

      3.2   Procedures

            HMO shall provide APS with a provider manual which describes the
            operational policies and procedures that APS and MHSA Providers must
            comply with as a condition of participation in HMO's Medicare
            Program. Further, HMO shall provide APS with prior written notice in
            the event of any changes to the procedures, including, but not
            limited to, changes in the benefits covered under a Medicare
            Member's Evidence of Coverage.

      3.3   Notification of Benefit Changes

            Prior to the effective date of this Amendment and any renewal term
            of this Amendment, HMO shall provide Copies of Medicare Member's
            Evidence of Coverage to APS, which shall describe Medicare Covered
            Services.

4     COMPENSATION

      4.1   Capitation Payment

            HMO shall remit to APS the Medicare Capitation Payment amount set
            forth on ATTACHMENT B-3 of the Agreement pursuant to the terms of
            the Agreement and this Amendment. Further, APS agrees to accept
            payment from HMO as payment in full for Medicare MHSA Covered
            Services and shall not bill Medicare Members except as set forth in
            SECTION 4.2 of this Amendment.

                                     G-2-6
<PAGE>

      4.2   Hold Harmless and Continuation of Benefits

            4.2.1 APS agrees, and shall require MHSA Providers to agree, that in
                  no event, including but not limited to, HMO's nonpayment,
                  HMO's insolvency, or a breach of this Agreement, shall APS or
                  an MHSA Provider bill, charge, collect a deposit from, seek
                  compensation, remuneration or reimbursement from, or have any
                  recourse against, a Medicare Member or persons (other than the
                  HMO) acting on his/their behalf for services provided pursuant
                  to this Amendment. This provision does not prohibit APS or an
                  MHSA Provider from collecting Copayments, as specifically
                  provided in the Evidence of Coverage, or fees for non-Medicare
                  covered Services delivered o a fee-for-service basis to
                  Medicare Members provided the Medicare Member has agreed in
                  writing to be financially liable for such non-Covered Services
                  prior to the rendering of the non-Covered Services.

            4.2.2 APS agrees that in the event of the HMO's insolvency or other
                  cessation of operations benefits to Medicare Members will
                  continue through the period for which premium has been paid,
                  and that benefits to Medicare Members confined in an inpatient
                  facility on the date of insolvency or other cessation of
                  operations will continue until the Medicare Member's
                  discharge.

            4.2.3 APS agrees that this SECTION 4.2 shall survive the termination
                  of this Amendment regardless of the reason for termination,
                  including HMO's or APS's insolvency, and shall be construed to
                  be for the benefit of the Medicare Members.

            4.2.4 APS agrees that this SECTION 4.2 supersedes any oral or
                  written contrary agreement now existing or hereafter entered
                  into between the APS and Medicare Members or persons acting on
                  their behalf insofar as such contrary agreement relates to
                  liability for payment for, or continuation of Medicare MHSA
                  Covered Services provided under the terms and conditions of
                  this Amendment.

            4.2.5 HMO shall not make any modifications, additions, or deletions
                  to the provisions of this SECTION 4.2 without prior written
                  approval of the Secretary of Health and Human Services or
                  his/her designee.

                     SPECIAL TERMS RELATING TO MHSA SERVICES
                     RELATING TO THE MEDICARE+CHOICE PROGRAM

      1. GOVERNMENT RIGHT TO INSPECT. APS shall give the U. S. Department of
Health and Human Services (HHS) and U. S. General Accounting Office (GAO), and
their authorized designees, the right to audit, evaluate and inspect all books,
contracts, medical records, patient care documentation and other records of APS
relating to this Agreement with CHC and to services furnished to the
Medicare+Choice Program ("M+C") Members and other Medicare Members (hereinafter
"Advantra Members") during the term of the Agreement and for a period of 6 years
following termination or expiration of the Agreement for any reason, or until
completion of an audit, whichever is later, unless such time frame is extended
pursuant to 42 C. F. R. ss. 422.502(e)(4) (such as in the event of fraud). This
provision shall survive termination of the Agreement.

      2. PRIVACY/CONFIDENTIALITY. APS agrees to safeguard the privacy of any
information that identifies a particular Advantra Member in accordance with
federal and state laws and Plan policy; and maintain all "Advantra" Members'
records in an accurate and timely manner.

      3. NON-DISCRIMINATION BASED ON HEALTH STATUS. APS shall not deny, limit or
condition coverage or the furnishing of health care services or benefits to
Advantra Members based on health factors, such as medical condition (including
mental as well as physical illness), claims experience, receipt of health care,
medical history, genetic information, evidence of insurability (including
conditions arising out of acts of domestic violence), and disability. See also
APS' non-discrimination obligations as set forth in Section 13 below.

      4. IDENTIFICATION OF ADVANTRA MEMBERS WITH COMPLEX OR SERIOUS MEDICAL

enrollment of each such person.

      7. PROFESSIONALLY RECOGNIZED STANDARDS. APS shall arrange for Covered
Services to Advantra Members in a manner consistent with professionally

notified by CHC for reason of coordination of benefits or subrogation. APS and
APSH shall not bill, charge, collect a deposit from, seek compensation,
remuneration or reimbursement from, or have claim or recourse against an
Advantra Member or anyone acting on behalf of an Advantra Member, under any
circumstance unless explicitly approved for reason of coordination of benefits

APS and APSH further agree that-this paragraph shall survive the termination (or
expiration) of this Agreement regardless of cause of such termination, and that
they have not, and will not, enter into any agreement with an Advantra Member or
any other party contrary to this paragraph. This provision shall not prohibit
collection of charges for services which are not Covered Services as defined in
the relevant Evidence of Coverage provided that the Covered Person has been
informed in advance of delivery of such services that such services are not
covered and the Covered Person patient has agreed in writing, in a form
substantially similar to the one attached hereto, to accept responsibility for
payment for such services. Nor shall this provision prohibit payment for any
Covered Services delivered after expiration of benefits under the relevant
Evidence of Coverage. APS and/or APSH shall require MHSA Providers to submit to
CHC any Advantra Member's written acknowledgement to accept responsibility for
non-covered services provided by MHSA Providers.

      Any modifications, additions or deletions to the provisions of this
section shall become effective on a date no earlier than fifteen days after the
Commissioner of Insurance of the relevant state of has received written notice
of such proposed changes.

becomes insolvent, through the date of each such Member's discharge or for the
remainder of the period for which the Advantra Member's Medicare premium has
been paid, and such continuation of services shall be made in accordance with
the terms and conditions of the Agreement as it may be amended and in effect at
the time, including but not limited to the compensation rates and terms set
forth therein. This paragraph shall survive termination of the Agreement.

      10. DELEGATION. If CHC in a separate contract has delegated to APS certain
of CHC's M+C obligations, APS shall perform such obligations as set forth
between the parties and in compliance with all applicable Medicare and other
federal laws, regulations and Governmental pronouncements and the terms of this
Amendment. In the event that CHC, an HMO Subsidiary, an Operating Unit or CMS
determine that such delegated functions have not been performed satisfactorily,
or if requisite reporting and disclosure requirements are not otherwise fully
met in a timely manner, CHC may initiate one or all of the following remedial
measures to effectuate CHC's ultimate responsibility to its HMO Subsidiaries and
Operating Units for the performance of all M+C requirements:

      a. APS shall develop written action plans to describe how APS shall
correct the standards which do not meet compliance requirements within two weeks
of receipt of written notice of non-compliance by CHC. APS shall maintain its
right to demonstrate its compliance with such standards. In the event of a
dispute between APS and CHC regarding the achievement of such compliance, either
party may refer to the CMS regulations and interpretation, and request a formal
written clarification from CMS.

      b. Written action plans shall include specific timeframes for completion,
and shall identify APS staff members responsible for ensuring compliance with
such standards.

      c. CHC may re-audit APS on site or via paper documentation in order to
ensure compliance with action plans. CHC must give APS at least two weeks notice
prior to an on-site audit.

      d. CHC may revoke delegation of activities to APS at any time, in the
event there is a finding that APS is not conducting such activities in
compliance with CHC's reasonable expectations, or NCQA or CMS standards.

      If the Agreement or another written agreement between CHC and APS
delegates to APS the responsibility for selection and/or credentialing of
providers, the HMO Subsidiaries and Operating Units nonetheless retain the right
to approve, suspend, or terminate any individual provider selected or
credentialed by APS. APS' credentialing process shall be subject at all times to

MHSA Providers and "downstream" entities with which APS contracts, accurately
disclose(s) such payment and incentive arrangements to CHC and CMS upon request
(and in the format requested). APS agrees to require that all such payment and
incentive arrangements shall be structured consistent with the physician
incentive plan requirements and limitations imposed by the Medicare+Choice
Program as set forth in 42 C. F. R. ss.ss. 422.208 and 422.210.

      12. PROMPT PAYMENT. APS agrees to use reasonable efforts to adjudicate

eligible Advantra Member; (c) billed according to arrangements set forth in this
Agreement and CHC policy; and (d) have no third party involvement.

      13. COMPLIANCE WITH FEDERAL AND STATE LAWS. APS agrees to comply, and to
require all MHSA Providers and "downstream" entities with which APS contracts to

policies, QA programs and medical management programs.

      17. TERMINATION WITHOUT CAUSE. In the event that APS and/or APSR or CHC
seeks to terminate the Agreement other than for "cause" as defined in the
Agreement, such party seeking to terminate shall provide the other party with at
least 60 days advance written notice. The foregoing shall not be deemed or
construed as affording CHC a right to terminate the Agreement other than
pursuant to Section 15 of the Agreement, as it may be amended from time to time.

      18. EXCLUSION OF CERTAIN PERSONS. APS and APSH shall not; and shall
require that no MHSA Provider or "downstream" entity with which APS contracts
shall, employ or contract for the provision of health care, utilization review,
medical social work or administrative services with any individual excluded from
participation in Medicare under Section 1128 or 1128A of the Social Security
Act. APS and APSH hereby certify that no such excluded person currently is
employed by or under contract with APS and/or APSR or with any MHSA Provider or
"downstream" entity with which APS contracts relating to the furnishing of these
services to Advantra Members.

      19. COMPLIANCE WITH APPEALS PROCEDURES REQUIREMENTS. APS shall, and shall

contracts to cooperate and comply with all requirements of Medicare, the HMO
Subsidiaries and Operating Units regarding the processing of Advantra Member

requested for such purpose. Information requested from APS for purposes of
processing a Member's request for immediate PRO review of noncoverage of
inpatient hospital care shall be provided to HMO Subsidiaries or Operating Units
within one (1) full business day immediately following the day such HMO
subsidiary or Operating Unit makes the request.

      20. EFFECTIVENESS OF CONTRACTS AND AMENDMENTS. No new contract with APS
and/or APSH, or provider or "downstream" entity with which APS and/or APSR
contracts, shall be effective unless signed and dated by the relevant parties.
The foregoing shall not apply to amendments to existing contracts which shall be
signed and dated by APS or APSH, as applicable. The parties agree to comply with
the laws, regulations and other requirements related to the Medicare+Choice
Program. The parties further agree to meet and discuss in good faith any change
or amendment to this Agreement that is required due to a change in law,
regulation or other requirement relating to the Medicare+Choice Program. The
parties shall use their best efforts to reach agreement on an amendment within
thirty (30) days of commencing negotiation, or by the effective date of the
change in the Medicare+Choice Program that necessitated the amendment if later.
However, no modification or amendment to this Agreement shall be effective
unless reduced to writing and agreed to by APS, APSH and CHC.

      21. COMPLIANCE WITH POLICIES, PROCEDURES AND MANUALS. APS and MSR agree,
and shall require all MHSA Providers and "downstream" entities with which APS
contracts to agree, to comply with all applicable CHC policies, procedures and
manual provisions, which specifically include but are not limited to, where

                                     G-3-4
<PAGE>

      22. CLAIMS FOR PAYMENT. As required by 42 C. F. R. ss.1001.952(m)(l)(i),
in the case of services furnished to Advantra Members, APS and/or MSR shall not
claim payment in any form from CMS or from any other agency of the United States
or from any state for items and services furnished in accordance with this
Agreement, except as may be approved by CMS or a State agency, nor shall APS
and/or APSH otherwise engage in any shifting of costs or seek increased payments
from the Medicare+Choice Program or any State health care program as a result of
furnishing such services to Advantra Members.

      23. Y2K COMPLIANCE. APS and APSH shall ensure, and shall require for all
MHSA Providers and "downstream" entities with which APS contracts, that all
necessary actions and system changes to internal mission-critical systems have
been made and tested so that they are Year 2000 compliant. Year 2000 compliant
means that APS and/or APSH's information technology accurately processes date
and time data (including, but not limited to, calculating, comparing, and
sequencing) from, into, and between the nineteenth, twentieth and twenty-first
centuries, and the years 1999 and 2000 and leap year calculations. Further, Year
2000 compliant information technology, when used in combination with other
information technology, must accurately process date and time data if the other
information technology property exchanges date and time data with it.
Mission-critical systems are defined as those systems and interfaces which
materially affect APS' and/or APSH's accurate and timely performance of the
functions under the Agreement.

      24. HEALTHCARE INTEGRITY AND PROTECTION DATA. APS shall require MHSA
Providers to report in writing to CHC within thirty (30) calendar days of the
MRSA Provider's knowledge any and all civil judgments and "other adjudicated
actions or decisions" against the MHSA Provider related to the delivery of any
health care item or service (regardless of whether the civil judgment or other
adjudicated action or decision is the subject of a pending appeal).

      "Other adjudicated actions or decisions" means any action taken by a
governmental entity or a health plan against a health care provider, supplier or
practitioner based on acts or omissions that affect or could significantly
affect the delivery or payment of a health care item or service. An action taken
following adequate notice and hearing requirement that meets the standards of
due process set out in section 412(b) of the Health Care Quality Improvement Act
(42 U. S. C. ss. 11112(b)) also would qualify as a reportable action under this
definition. The fact that the MHSA Provider elects not to use the due process
mechanism provided by the authority bringing the action is immaterial, as long
as such a process is available to the subject before the adjudicated action or
decision is made final.

      In compliance with CHC's policy on the reporting of Health Care Integrity
and Protection Data, APS and/or APSH shall report to CHC in writing within
thirty (30) calendar days of APS and/or APSR's knowledge the information set
forth in the CHC Manual.

      25. INCONSISTENCIES. In the event of any inconsistencies between this
Attachment G-3 and any provision of the Agreement with respect to Advantra
Members, the provisions of this Attachment shall govern.

      26. SUBCONTRACTS AND "DOWNSTREAM" ENTITIES. APS shall ensure that all of
the requirements set forth in this Attachment that are applicable to MHSA
Providers and/or "downstream" entities with whom APS contracts or any downstream
entity to whom APS delegates any of its obligations under the Agreement (as
authorized pursuant to this Agreement with CHC) shall be incorporated into APS'
contract with such provider or entity. APS shall enforce those provisions in its
contracts to the fullest extent of the law.

                        CAPITATED BENEFICIARY ADJUSTMENT

Subject to Section 15.3, the Capitated Beneficiary Adjustment shall equal the
following:

      Cash payment = (X/Y)*Z*T

      Stock delivery = (X/Y)*S*T

Where:

      X = the number of Capitated Members set forth opposite the name of the
          relevant Original HMO Subsidiary or Original Operating Unit on
          Attachment K

      Y = 575,418, representing the aggregate number of Capitated Members of
          all of the Original HMO Subsidiaries as of August 31, 1997

      Z = $7,000,000

      S = $3,895,462

      T = a fraction, the numerator of which equals 120 minus the aggregate
          number of months (including partial months) from the Closing Date
          through the date of determination of the amount of the relevant
          Capitated Beneficiary Adjustment, and the denominator of which
          equals 120.

As provided in Section 15.3:

      (i)   stock to be delivered as part of a Capitated Beneficiary Adjustment
            shall be valued at the Current Market Price, as determined pursuant
            to Section 15.3.4;

      (ii)  if CHC shall have sold, transferred or otherwise disposed of any
            shares of APSH Common Stock, then in lieu of delivering such shares
            as part of the Capitated Beneficiary Adjustment, CHC may deliver
            cash in an amount equal to $1.44 per share (subject to appropriate
            adjustment in the event of any stock split, stock dividend or other
            subdivision or combination of the outstanding shares of APSH Common
            Stock) for each such shares; and

(iii) in no event will CHC ever be required to deliver to APSH more than
2,705,182 shares of APSH Common Stock in the aggregate (subject to appropriate
adjustment in the event of any stock split, stock dividend or other subdivision
or combination of the outstanding shares of APSH Common Stock).
