having its principal office at 4900 North Lamar Boulevard, 4th Floor, Austin
Texas 78751, and AMERICAID Texas, Inc. d/b/a AMERIKIDS ("CONTRACTOR"), a
corporation organized under the laws of the State of Texas, possessing a
certificate of authority issued by the Texas Department of Insurance to operate
as a health maintenance organization and having its principal office at 2730
North Stemmons Freeway, Suite 608, West Tower, Dallas, Texas 75207.

       The Parties agree that the following terms and conditions apply to the
services to be provided by CONTRACTOR under this Agreement in consideration of
certain payments to be made by HHSC.


               ARTICLE 2. BACKGROUND, INDUCEMENTS AND OBJECTIVES


       SECTION 2.01 BACKGROUND.

       (a)    Federal legislative authorization.

       This Agreement is entered into in connection with the Texas Legislature's
decision to participate in the federally-authorized State Children's Health
Insurance Program ("CHIP"). CHIP is authorized under Title XXI of the federal
Social Security Act, 42 U.S.C. Sections 1397aa-1397jj. The CHIP program is an
optional joint state-federal program designed to provide affordable insurance to
low-income families with uninsured children.

       (b)    State enabling legislation.

       Approximately 1.4 million children in Texas are uninsured. The costs,
both economic and social, to the State of Texas are immeasurable. In recognition
of this need, the 76th Texas Legislature authorized the state's participation in
the CHIP program. The enabling legislation, Senate Bill 445, is codified as
Chapter 62, Health & Safety Code. The principal objective of the state
legislation is to provide primary and preventative health care to low-income,
uninsured children of Texas, including children with special health care needs,
who are not served by or eligible for other state-assisted health insurance
programs.

       (c)    State child health plan.

       Under chapter 62 of the Health and Safety Code, HHSC is directed to
develop and file with the federal government a state-designed health plan
program that ensures the state's eligibility for federal funding under Title XXI
of the Social Security Act. The federal government has approved the State's
plan. HHSC desires the participation of qualified organizations to assist with
the implementation of the plan in Texas.

       (d)    Participation of the private sector.

       As expressed in section 62.055, Health & Safety Code, the Texas
Legislature intends that HHSC, in administering the state child health plan,
maximize the use of private resources, including nonprofit organizations. In
fulfilling this mandate, HHSC has solicited assistance with many aspects of the
program, including delivery of health plan coverage to CHIP-eligible children
through health maintenance organizations (HMOs).

       (e)    Procurement of comprehensive health plan coverage through health
              maintenance organizations (HMOs).

Request for Proposals ("RFP") dated August 2, 1999. The procurement that is the
subject of this Agreement is undertaken as a "best value" procurement under to
the terms of Chapter 531, Texas Government Code, Chapter 62, Health & Safety
Code, and section 2155.144, Government Code. In response to the RFP, CONTRACTOR
submitted its Proposal, dated September 28, 1999 (the "Proposal"). Following
review of proposals, the evaluators appointed by HHSC recommended CONTRACTOR's
Proposal as a best value for the state in one or more of the coverage areas in
the state. HHSC desires to implement the terms of CONTRACTOR's Proposal, subject
to the terms and conditions of this Agreement.

              Agreement to uninsured, low-income children, and the needs and
              requirements of the State as provided in the Agreement;

              (4)    CONTRACTOR has had the opportunity to review and understand

negotiate in good faith appropriate modifications or alterations to the
Agreement and any schedule(s) or attachment(s) made a part of this Agreement.
Such modifications or alterations must equitably adjust the terms and conditions
of this Agreement and must be limited to those provisions of this Agreement
affected by the change.

       (b)    Modifications resulting from imposition of remedies.

       This Agreement may be modified under the terms of Article 20 (relating to

              (1)    If HHSC seeks modifications to the Agreement as a condition
              of any annual extension, HHSC's notice to CONTRACTOR will specify
              those modifications to the Scope of Work, the Agreement pricing
              terms, or other terms and conditions of the Agreement HHSC seeks.

              (2)    Modifications proposed by HHSC may apply to the services

                            (C)    The anticipated time schedule for

              (4)    Upon HHSC's receipt of a Change Order and Change Order
              Response, the Parties shall negotiate a resolution of the
              requested Change in good faith. The Parties will exchange

General of the United States, the United States Department of Health and Human
Services, a State or Federal law enforcement agency, or their representatives

documents, along with interviews with key staff) not resulting from a complaint.
HHSC will provide CONTRACTOR written notice at least ten (10) business days
prior to any site visit at CONTRACTOR's offices (a general inspection and
interviews with CONTRACTOR's staff) not resulting from a complaint. If an
on-site visit or audit is the result of a complaint against CONTRACTOR, HHSC
will send written notice to CONTRACTOR via facsimile at least 24 hours prior to

       SECTION 9.03 ACCESS TO RECORDS, BOOKS, AND DOCUMENTS.

       (a)    CONTRACTOR must provide the officials and entities identified in
paragraph (b) of this section 9.03 with prompt, reasonable, and adequate access

                  ARTICLE 10. TERMS AND CONDITIONS OF PAYMENT.


       SECTION 10.01 MONTHLY PREMIUM PAYMENTS.

       (a)    CONTRACTOR agrees to provide the Services and Deliverables
described in this Agreement for monthly premium payments to be paid by HHSC to
CONTRACTOR.

       (b)    CONTRACTOR understands and expressly assumes the risks associated
with the performance of the duties and responsibilities under this Agreement,
including the failure, termination or suspension of funding to HHSC, delays or
denials of required approvals, and cost overruns not reasonably attributable to
HHSC. To the extent that funding or required approvals are not provided,
CONTRACTOR is not further obligated to provide Services or Deliverables beyond
any Service or Deliverable for which HHSC can provide acceptable assurances of
available funding.

       (c)    CONTRACTOR further agrees that:

              (1)    No additional charges, fees, or costs will be added to the
              monthly premium amount and the delivery supplemental payment
              described in section 10.03 or sought except for properly
              authorized and executed Change Orders; and

              (2)    No other charges for tasks, functions, or activities that
              are incidental or ancillary to the delivery of the Services and
              Deliverables will be sought from HHSC or any other state agency,
              nor will the failure of HHSC or any other party to pay for such
              incidental or ancillary services entitle CONTRACTOR to withhold
              Services or Deliverables due under the Agreement.

       (d)    A CONTRACTOR's monthly premium payment will not be reduced for a
family's failure to make its premium payment. There is no relationship between
the per member/per month amount owed to an CONTRACTOR for coverage provided
during a month and the family's payment of its premium obligation for that
month.


       SECTION 10.02 TIME AND MANNER OF PREMIUM PAYMENT.

       CONTRACTOR will be paid based on per member/per month premiums and new
and current enrollment figures (including disenrollment adjustments to previous
monthly enrollment totals). The Administrative Services Contractor will convey
premiums payable information to CONTRACTOR for data reconciliation and to the
Management Services Contractor. CONTRACTOR must reconcile the data and report
any errors to the Management Services Contractor by the cut-off date of the next
month. The Management Services Contractor will pay



                                 Page 41 of 77
<PAGE>   42

CONTRACTOR by the first business day following the 14th day of each month.
CONTRACTOR must accept payment for premiums by direct deposit into CONTRACTOR's
account. For the first year of the Initial Term, these premium rates are:

--------------------------------------------------------------------------------------------
</TABLE>

       CONTRACTOR does not bill HHSC, the Administrative Services Contractor,
other state agencies, or institutions for the monthly premium payment.


       SECTION 10.03 DELIVERY SUPPLEMENTAL PAYMENT (DSP).

       HHSC shall pay to CONTRACTOR a one-time-per-pregnancy Delivery
Supplemental Payment (DSP) in the amount of $3,000.00 for each live or still
birth delivery. The one-time payment is made regardless of whether there is a
single birth or multiple births at the time of delivery. For purposes of this
section, a "delivery" is the birth of a live-born infant, regardless of the
duration of the pregnancy, or a stillborn (fetal death) infant of 22 weeks or
more gestation.

       CONTRACTOR should make its best effort to report all deliveries to the
Administrative Services Contractor within 10 days of the delivery and no later
than 45 days from the date of delivery. No DSP will be made for deliveries that
are not reported by CONTRACTOR to the Administrative Services Contractor within
120 days from the receipt of claim, or within 60 days from the date of discharge
from the hospital for the stay related to the delivery, whichever is later.

       HHSC reserves the right to audit the claims submitted for DSP to ensure
the accuracy of those claims. The DSP will be paid to CONTRACTOR as part of the
monthly premium payment after receiving an accurate report from CONTRACTOR.


       SECTION 10.04 PREMIUM RATES AFTER THE FIRST YEAR OF THE INITIAL TERM.

       (a)    Second year.

       HHSC will review the methodology submitted by CONTRACTOR for determining
subsequent premium rate changes and re-examine the premium rates paid to
CONTRACTOR during the first year of the Initial Term to determine if a rate
change is needed for the second year of the Initial Term. HHSC will establish
the premium rates for each year. HHSC will provide any proposed revisions to the
premium rate changes for the second year of the Initial Term no later than 30
days before the first Anniversary Date. If CONTRACTOR disagrees with any
proposed revisions to the premium rates, the Parties will exchange actuarial
data supporting each of their positions as to what the premium rates for the
second year should be. HHSC and CONTRACTOR only will negotiate in good faith to
reach an agreement on the premium rates for the second year. Failing timely
agreement, CONTRACTOR and HHSC will select a neutral actuary who is agreeable to
both parties to review each of the Party's recommended premium rates and the
supporting actuarial data. The Parties will share the cost of the neutral
actuary equally. Full payment to the actuary may be made by CONTRACTOR, with
HHSC reimbursing CONTRACTOR for HHSC's share. The neutral actuary will make
non-binding recommendations



                                 Page 42 of 77
<PAGE>   43

for the premium rates for the second year after reviewing each of the Party's
data. HHSC will then determine the premium rates for the second year.

       (b)    Third year.

       HHSC will review the methodology submitted by CONTRACTOR for determining
subsequent premium rate changes and re-examine the premium rates paid to
CONTRACTOR during the first and second years of the Initial Term to determine if
a rate change is needed for the third year of the Initial Term. HHSC will
establish the premium rates for each year. HHSC will provide any proposed
revisions to the premium rate changes for the third year of the Initial Term no
later than 30 days before the second Anniversary Date. If CONTRACTOR disagrees
with any proposed revisions to the premium rates, the Parties will exchange
actuarial data supporting each of their positions as to what the premium rates
for the third year should be. HHSC and CONTRACTOR only will negotiate in good
faith to reach an agreement on the premium rates for the third year. Failing
timely agreement, CONTRACTOR and HHSC will select a neutral actuary who is
agreeable to both parties to review each of the Party's recommended premium
rates and the supporting actuarial data. The Parties will share the cost of the
neutral actuary equally. Full payment to the actuary may be made by CONTRACTOR,
with HHSC reimbursing CONTRACTOR for HHSC's share. The neutral actuary will make
non-binding recommendations for the premium rates for the third year after
reviewing the Parties' data. HHSC will then determine the premium rates for the
third year.


       SECTION 10.05 ADJUSTMENTS TO PREMIUM PAYMENTS.

       As provided below, HHSC or the Administrative Services Contractor may
adjust or recoup premiums paid to CONTRACTOR in error, which may be either human
or machine error on the part of HHSC. HHSC may recoup or adjust premiums paid to
CONTRACTOR if a CHIP-eligible child is enrolled into CONTRACTOR in error and
CONTRACTOR provides no covered services to the child for the period of time for
which the monthly premium payment was made. If CONTRACTOR arranged for services
to be provided to the Member as a result of the error during the time period for
which the monthly premium payment was made, no recoupment will occur. Under no
circumstances may HHSC recoup premiums paid for a period greater than two (2)
months.

       HHSC or the Administrative Services Contractor may recoup monthly premium
payments paid to CONTRACTOR if an Member for whom the monthly premium payment is
made was deceased during any full month for which CONTRACTOR received a premium
payment for that Member.

       HHSC or the Administrative Services Contractor may adjust a monthly
premium or recoup a monthly premium payment made to CONTRACTOR for a Member if
the Member's eligibility status is changed, corrected, or retroactively adjusted
as a result of error. Adjustments to premium or recoupment may be appealed by
CONTRACTOR using the dispute resolution process outlined in section 20.16.


       SECTION 10.06 EXPERIENCE REBATE.

       For the Initial Term, CONTRACTOR must pay to HHSC an experience rebate
calculated in



                                 Page 43 of 77
<PAGE>   44

accordance with the tiered rebate method listed below based on the excess of
allowable CHIP HMO revenues over allowable CHIP HMO expenses as measured by any
positive amount on Line 7, Net Income Before Taxes, of "Part 1: CHIP Financial
Summary, All Coverage Groups Combined" of the annual Financial-Statistical
Report contained in Appendix D, as reviewed and confirmed by HHSC.

--------------------------------------------------------------------------------
</TABLE>

       The financial governance document for calculating the experience rebate
is the governance document used in the Texas Medicaid STAR program on the
Effective Date of this Agreement.

       Losses incurred for one contract year may be carried forward only to the
next contract year. If CONTRACTOR operates in multiple CHIP Service Areas,
losses in one CHIP Service Area cannot be used to offset net income before taxes
in another CHIP Service Area.

       CONTRACTOR may subtract from an experience rebate that is owed to HHSC
any expenses for population-based health initiatives that have been approved by
HHSC.

       A population-based initiative is a project or program designed to improve
some aspect of quality of care, quality of life, or health care knowledge for
children and/or their adult caretakers, as a whole.

       There will be two settlements for payment(s) of the state share of the
experience rebate. The first settlement shall equal 100% of the state share of
the experience rebate as derived from Line 7, Net Income Before Taxes, of "Part
1: CHIP Financial Summary, All Groups Combined" of the annual CHIP
Financial-Statistical (CFS) Report contained in Appendix D and shall be paid on
the same day the first annual CFS Report is submitted to the Administrative
Services Contractor or HHSC. The second settlement shall be an adjustment to the
first settlement and shall be paid to HHSC on the same day that the second
annual CFS Report is submitted to the Administrative Services Contractor or HHSC
if the adjustment is a payment from CONTRACTOR to HHSC. HHSC or its agent may
audit or review the CFS reports. If HHSC determines that corrections to the CFS
reports are required based on an HHSC audit/review or other documentation
acceptable to HHSC, to determine an adjustment to the amount of the second
settlement, then final adjustment shall be made within two years from the date
that CONTRACTOR submits the second annual CFS report. CONTRACTOR must pay the
first and second settlements on the due dates for the first and second CFS
reports respectively as identified in section 17.02. HHSC may adjust the
experience rebate if HHSC determines that CONTRACTOR has paid affiliates amounts
for goods or services that are higher than the fair market value of the goods
and services in that CHIP Service Area. Fair market value may be



                                 Page 44 of 77
<PAGE>   45

based on the amount CONTRACTOR pays a non-affiliate(s) or the amount another
health maintenance organization pays for the same or similar service in that
CHIP Service Area. HHSC has final authority in auditing and determining the
amount of the experience rebate.


       SECTION 10.07 RESTRICTION ON ASSIGNMENT OF FEES.

       During the term of the Agreement CONTRACTOR may not, directly or
indirectly, assign to any third party any beneficial or legal interest of
CONTRACTOR in or to any payments to be made by HHSC pursuant to this Agreement.


       SECTION 10.08 LIABILITY FOR TAXES.

       HHSC is not responsible in any way for the payment of any Federal, state
or local taxes related to or incurred in connection with the Services or
Deliverables or this Agreement. CONTRACTOR must pay and discharge any and all
such taxes, including any penalties and interest.


       SECTION 10.09 LIABILITY FOR EMPLOYMENT-RELATED CHARGES AND BENEFITS.

       CONTRACTOR will perform work under this Agreement as an independent
contractor and not as agent or representative of HHSC. CONTRACTOR is solely and
exclusively liable for all taxes and employment-related charges incurred in
connection with the performance of this Agreement. HHSC will not be liable for
any employment-related charges or benefits of CONTRACTOR, such as workers
compensation benefits, unemployment insurance and benefits, or fringe benefits.


       SECTION 10.10 LIABILITY FOR OVERTIME COMPENSATION.

       CONTRACTOR will be solely responsible for any obligations of overtime pay
due employees.


    ARTICLE 11. CHIP ELIGIBILITY, ENROLLMENT, DISENROLLMENT, AND COST-SHARING


       SECTION 11.01 CHIP ELIGIBILITY.

       (a)    Generally.

       CHIP eligibility will be determined by the Administrative Services
Contractor. The Administrative Services Contractor will enroll and disenroll
eligible individuals into and out of CHIP. Parents or guardians will enroll
eligible individuals in a health plan.

       (b)    Continuous coverage for first twelve months.

       A child who is CHIP-eligible will, for at least the first year of CHIP,
have twelve months of continuous coverage. That coverage begins on the first day
of the month following the child's enrollment into a health plan unless
enrollment occurs after the cut-off date, in which case


                                  Page 45 of 77
<PAGE>   46

coverage begins on the first day of the next month.

       (c)    Pregnant Members and infants.

       Becoming pregnant, in and of itself, does not make a Member ineligible
for CHIP. If, after becoming pregnant, a Member chooses to apply for Medicaid
and is determined to be Medicaid-eligible, she is no longer eligible for CHIP.
The Administrative Services Contractor will notify the Member about her
potential Medicaid eligibility and of her ability to apply for Medicaid and will
provide appropriate resource information.

       Infants are automatically enrolled in the mother's CHIP health plan at
birth with CHIP eligibility and re-enrollment following the same timeframe as
those of the mother.

       CONTRACTOR through electronic means or the providers through calls to the
provider hotline will notify the Administrative Services Contractor when a
pregnancy is diagnosed. The administrative contractor will suspend the pregnant
Member's eligibility expiration date after notification is received. The
Administrative Services Contractor will unsuspend the mother's eligibility
expiration date and set the mother's and baby's eligibility expiration dates at
the later of (1) the end of the second month following the month of the baby's
birth or (2) the date when the mother's eligibility would have expired if it had
not been suspended during her pregnancy.

       To further ensure the reliability of the data, families also will be
encouraged to notify the Administrative Services Contractor by phone or in
writing when delivery of a baby to a CHIP-enrolled Member occurs.

       (d)    Span of Coverage.

       If a Member's effective date of coverage occurs while the Member is
confined in a hospital, the CONTRACTOR is responsible for the Member's costs of
Covered Services beginning on the Effective Date of Coverage. For each day that
the Member is hospitalized beginning on the Effective Date of Coverage, HHSC
will pay to CONTRACTOR $700 for non-ICU care and $1400 for ICU care. If a Member
is disenrolled while the Member is confined in a hospital, CONTRACTOR's
responsibility for the Member's costs of Covered Services terminates on the Date
of Disenrollment. Six months after the Implementation Date, the Parties will
review CONTRACTOR's data, and if either party believes that these payments are
insufficient, either Party can instigate the Change Order process set out in
Article 8. The Parties agree to negotiate any requested Change Order in good
faith.


       SECTION 11.02 ENROLLMENT.

       To enroll in CONTRACTOR's health plan, the Member's permanent residence
must be located within CONTRACTOR's CSA.

       HHSC makes no guarantees or representations to CONTRACTOR regarding the
number of eligible Members who will ultimately be enrolled into CONTRACTOR's
health plan.

       The Administrative Services Contractor will electronically transmit to
CONTRACTOR new Member information, PCP selections, and change information
applicable to active Members five




                                 Page 46 of 77
<PAGE>   47

business days prior to the first day of each month. This monthly transmittal
date is defined as the "cut-off date." Twelve months of continuous coverage
begins on the first day of the month following enrollment unless enrollment
occurs after the cut-off date, in which case coverage begins on the first day of
the next month. CONTRACTOR must accept all persons who reside within
CONTRACTOR's CSA and chose to enroll in CONTRACTOR's health plan without regard
to the Member's health status or any other factor.

       A Member is enrolled in a health plan initially selected for twelve (12)
months from the date that the individual is first covered by that health plan or
the applicable time period if the Member is pregnant as is set out in section
11.01(c). However, CONTRACTOR must accommodate Member requests to change health
plans for exceptional reason or good cause including, but not limited to:

       (a)    permanent relocation from a CHIP Service Area; or

       (b)    permanent relocation within CONTRACTOR's CSA that necessitates a
change in the Member's Primary Care Provider that CONTRACTOR cannot accommodate
within the prescribed TDI access standards;

       Additional reasons that qualify as an exceptional reason or good cause
will be determined by HHSC on a case-by-case basis or by rule. Members may
change health plans the first day of the month following the month in which
exceptional reason or good cause situation occurred, in accordance with the same
cut-off processing timeframes applied to new Members. All changes must be
handled through the Administrative Services Contractor. If a Member changes
health plans while the Member is confined in a hospital, the health plan from
which the Member is moving is responsible for all charges until the Member is
discharged.

       There is no retroactive enrollment in CHIP.


       SECTION 11.03 RE-ENROLLMENT.

       At the beginning of the tenth month of coverage, the Administrative
Services Contractor will send a notice to the family outlining the next steps
for renewal or continuation of coverage. The Administrative Services Contractor
will also send a notice to CONTRACTOR regarding its Members and to a
community-based outreach organization providing follow-up assistance in the
Members' areas. To promote continuity of care for children eligible for
re-enrollment, CONTRACTOR may facilitate re-enrollment through reminders to
Members and other appropriate means. Failure of the family to respond to the
Administrative Services Contractor's renewal notice will result in disenrollment
from the plan and from CHIP.


       SECTION 11.04 DISENROLLMENT DUE TO LOSS OF ELIGIBILITY.

       For those Members who are disenrolled because they are no longer eligible
for CHIP, CONTRACTOR will receive from the Administrative Services Contractor
notice informing CONTRACTOR that the Members' coverage will end on a particular
date. Disenrollment due to loss of eligibility includes, but is not limited to:

       "Aging-out" when a child turns nineteen;



                                 Page 47 of 77
<PAGE>   48

              Failure to re-enroll at the conclusion of the 12-month eligibility
              period;

              Change in health insurance status, such as a child enrolling in an
              employer-sponsored health plan;

              Failure to meet monthly cost-sharing obligation;

              Death of a child;

              The child permanently moves out of the state; and

              Data match with the Medicaid system indicates dual enrollment in
              Medicaid and CHIP.

       If a child is disenrolled from CHIP, the child loses his or her CHIP
eligibility and must re-apply for a determination of CHIP eligibility in the
future.

       Regardless of the reason for retroactive disenrollment, recoupment of
premium payments by HHSC shall be in accordance with section 10.05. Under no
circumstances may HHSC recoup premiums paid for a period greater than two (2)
months.


       SECTION 11.05 DISENROLLMENT BY CONTRACTOR.

       CONTRACTOR has a limited right to request a Member be disenrolled from
CONTRACTOR without the Member's consent. HHSC must approve any CONTRACTOR
request for disenrollment of a Member for cause within thirty (30) days from
date request is received. Disenrollment of a Member may be permitted for the
reasons set out in 11 T.A.C. Section 11.506(a)(3). Disenrollment of a Member at
the request of CONTRACTOR may not occur during an inpatient stay.

       CONTRACTOR must notify the Member of HHSC's approval of the disenrollment
of the Member. IF THE MEMBER DISAGREES WITH THE DECISION TO DISENROLL THE MEMBER
FROM CONTRACTOR, CONTRACTOR MUST NOTIFY THE MEMBER OF THE AVAILABILITY OF
CONTRACTOR'S COMPLAINT PROCEDURE.

       THE CONTRACTOR CANNOT REQUEST A DISENROLLMENT BASED ON ADVERSE CHANGE IN
THE MEMBER'S HEALTH STATUS OR UTILIZATION OF SERVICES THAT ARE MEDICALLY
NECESSARY FOR TREATMENT OF A MEMBER'S CONDITION.


       SECTION 11.06 COST-SHARING.

       Health care providers within CONTRACTOR's network are responsible for
collecting all Member copayments and deductibles at the time of service. No
co-payments apply, at any income level, to well-child or well-baby visits or
immunizations.

       No co-payments for families under 100% of the federal poverty level (FPL)

       Co-payments for families between 100% and 150% FPL are as follows:

                     $2 per office visit


                                 Page 48 of 77
<PAGE>   49

                     $5 per emergency room visit
                     $1 per prescription valued up to and including $15; $2 per
                     prescription valued at more than
                     $15 (based on retail value)
                     An annual self-declared co-payment cap of $100 per family

       Co-payments for families above 150% FPL and up to and including 185% FPL
are as follows:

              $5 per office visit
              $25 per emergency room visit
              $5 per generic prescription and $10 per brand-name prescription

       Co-payments for families above 185% FPL are as follows:

              $10 per office visit
              $35 per emergency room visit
              $5 per generic prescription and $10 per brand-name prescription

       For families with incomes between 186% and 200% FPL, a per-family annual
deductible of $200 for inpatient hospital services and $50 for outpatient
hospital services will apply. This $50 deductible for outpatient hospital stays
does not include applicable pharmacy co-pays.

       Upon notification from the Administrative Services Contractor that a
family is approaching its cost-sharing limit for the Coverage Year, CONTRACTOR
will generate and mail to the Member a new Member ID card, showing that the
Member's cost-sharing obligation for that Coverage Year has been met. No
cost-sharing may be collected from these Members for the balance of their
Coverage Year.

       Except for costs associated with unauthorized non-emergency services
provided to a Member by out-of-network providers and for non-covered services,
the co-payments and deductibles outlined in this section are the only amounts
that a provider may collect from a CHIP-eligible family.

       Federal law prohibits charging co-payments or deductibles to Members of
Native American Tribes. The Administrative Services Contractor will notify
CONTRACTOR of Members who are Native Americans and who are not subject to
cost-sharing requirements. CONTRACTOR is responsible for educating providers
about the cost-sharing waiver for this population.

       A CONTRACTOR's monthly premium payment will not be reduced for a family's
failure to make its premium payment. There is no relationship between the per
member/per month amount owed to an CONTRACTOR for coverage provided during a
month and the family's payment of its premium obligation for that month.


                   ARTICLE 12. SCOPE OF CHIP COVERED SERVICES


       SECTION 12.01 BASIC REQUIRED COVERED SERVICES.

       CONTRACTOR is paid capitation for all services that are Covered Services
as described in the RFP. Unless the RFP specifies otherwise, CONTRACTOR may
determine if a covered service requires prior authorization, pre-certification,
or physician prescription. CONTRACTOR must pay for or reimburse for all
CHIP-covered services provided to Members for whom


                                 Page 49 of 77
<PAGE>   50

CONTRACTOR is paid capitation.

       Out-of-network and emergency services also must be provided in accordance
with the Texas Insurance Code and TDI regulations as they apply to HMOs. Covered
services are subject to change due to changes in federal law, changes in CHIP
policy, and/or responses to changes in medicine, clinical protocols, or
technology. If covered services change, the change will be the subject of a
change order as provided in Article 8 of this Agreement. Any proposed change in
the scope of Covered Services, as set out in the RFP, will be made through a
Change Order under Article 8 of this Agreement.


       SECTION 12.02 DRUG FORMULARIES.

       If CONTRACTOR utilizes a prescription drug formulary for Members,
CONTRACTOR must fully disclose its use of the formulary in its marketing
materials. During the term of the Agreement, CONTRACTOR cannot create a new
formulary or significantly revise an existing formulary; however, minor
revisions to include new drugs, or to remove drugs in compliance with FDA
directives are allowed. HHSC will determine if a revision is significant.
CONTRACTOR may revise the formulary on a annual basis, subject to HHSC review
and approval.

       SECTION 12.03 VALUE-ADDED SERVICES.

       CONTRACTOR must also provide or arrange for the provision of the
Value-added services, offered by CONTRACTOR in its proposal. CONTRACTOR must
provide these Value-added Services at no additional cost to HHSC. CONTRACTOR
must not pass on the cost of the Value-added Services to providers. CONTRACTOR
must specify the conditions and specific parameters regarding the delivery of
the Value-added Services in CONTRACTOR's marketing materials and evidence of
coverage or member handbook. CONTRACTOR must clearly state to Members any
limitations or conditions specific to the Value-added Services.

       Value-added Services can be added or removed only by written amendment of
this Agreement. CONTRACTOR cannot include a Value-added Service in any material
distributed to Members or prospective Members until this Agreement has been
amended to include that Value-added Service or CONTRACTOR has received written
approval of the suggested Value-added Service from HHSC pending finalization of
the amendment.

       If a Value-added Service is deleted by amendment, CONTRACTOR must notify
each Member that the service is no longer available through CONTRACTOR.
CONTRACTOR must also revise all materials distributed to prospective Members to
reflect the change in Value-added Services.


       SECTION 12.04 DENTAL SERVICES.

       CONTRACTOR is not responsible for providing preventive and therapeutic
dental services to Members. However, hospital and related medical charges, such
as anesthesia, that are associated with dental care, are covered CHIP services.
CONTRACTOR must provide access to facilities and physician services that are
medically necessary to support the dentist who is providing CHIP dental services
under general anesthesia or intravenous (IV) sedation. Covered Services relating


                                 Page 50 of 77
<PAGE>   51

to dental services are set forth in the RFP; this section does not expand the
scope of the Covered Services set out in the RFP.

       CONTRACTOR must inform network facilities, anesthesiologists, and PCPs
what authorization procedures are required, and how providers are to be
reimbursed for the preoperative evaluations by the PCP and/or anesthesiologist
and for the facility services. For dental-related medical emergency services,
CONTRACTOR must reimburse in-network and out-of-network providers in accordance
with federal and state statutes and regulations.


       SECTION 12.05 CASE MANAGEMENT SERVICES FOR CHILDREN WITH COMPLEX SPECIAL
HEALTH CARE NEEDS

       CONTRACTOR must have a documented process for identifying and tracking
the services of CHIP-eligible children with complex special health care needs
(CCSHCN).

       A child, a child's family, a health care provider, the CHIP
Administrative Services Contractor, or CONTRACTOR may preliminarily identify a
CCSHCN. CONTRACTOR must confirm the designation of a CCSHCN utilizing the
standardized screening instrument provided by the State. That screening
instrument will be substantially in the form attached hereto as Appendix E.
Procedures for collecting and processing data for CCSHCN are being developed;
however, CONTRACTOR will be required to electronically transmit CCSHCN
information to the Administrative Services Contractor on a quarterly basis.

       CCSHCN are eligible for case management services beyond the scope
normally provided to other CHIP-eligible children. CONTRACTOR must provide the
following enhanced case management services to CCSHCN as appropriate:

       (a)    Outreach and Informing

       Upon CCSHCN designation by CONTRACTOR, CONTRACTOR must contact the
CCSHCN's family to discuss covered services, including specialty services, the
family's right to select a specialist as a primary care provider, out-of-network
services applicable to the child's condition, if not available within network,
the availability of enhanced care coordination, and community referrals.

       (b)    Enhanced Care Coordination

       Upon CCSHCN designation by CONTRACTOR, CCSHCNs, their families, or their
health providers may request enhanced care coordination from CONTRACTOR.
CONTRACTOR must furnish a care coordinator when requested. CONTRACTOR may also
recommend to the CCSHCN's family that a care coordinator be furnished if
CONTRACTOR determines that care coordination would benefit the child. Care
coordinators are responsible for working with CCSHCN, their families, and their
health care providers to develop a seamless package of care in which primary,
acute, and specialty service needs are met through a single plan that is
understandable to the family. A written plan of care must be developed and
updated at least annually. The care coordinator will coordinate all services
with the PCP and, as necessary, with the child's pediatric specialty care
physician. The care coordinator also makes referrals for other community
services.

       (c)    Community Referrals


                                 Page 51 of 77
<PAGE>   52

       CONTRACTOR must make a best effort to implement a systematic process to
enlist the involvement of community organizations that may not be providing
CHIP-covered services but are otherwise important to the health and well being
of Members. CONTRACTOR also must make a best effort to establish relationships
with these community organizations in order to make referrals for CCSHCN and
other children who need community services. These organizations may include, but
are not limited to:

       Early Childhood Intervention Program (512/424-6745)

       Department of Mental Health and Mental Retardation (MHMR) ( 512/206-4830)

       Texas Department of Health (TDH) Title V Program (512/458-7321)

       Local School District (Special Education)

       Other state and local agencies and programs with jurisdiction over
children's services, including food stamps, Women, Infants, and Children's (WIC)
Program

       Texas Information and Referral Network

       Texas Commission for the Blind (TCB)

       Child-serving civic and religious organizations and consumer and advocacy
groups, such as United Cerebral Palsy, that also work on behalf of the CCSHCN
population


       SECTION 12.06 PRE-EXISTING CONDITIONS.

       CONTRACTOR may not impose any pre-existing condition limitations or
exclusions or require evidence of insurability to provide coverage to any
CHIP-eligible child.


       SECTION 12.07 COURT-ORDERED COMMITMENTS.

       CONTRACTOR must provide inpatient psychiatric services to Members under
the age of 19 who have been ordered to receive the services by a court of
competent jurisdiction under the provisions of Chapters 573 and 574 of the Texas
Health and Safety Code, relating to court-ordered commitments to psychiatric
facilities.

       Any modification or termination of services must be presented to the
court with jurisdiction over the matter for determination.

       A Member who has been ordered to receive treatment under the provisions
of Chapter 573 or 574 of the Texas Health and Safety Code cannot appeal the
commitment through CONTRACTOR's complaint or appeals process as described in
section 13.06 of this Agreement.

       CONTRACTOR must comply with 28 TAC Sections 3.8001, et seq. regarding
utilization review of chemical dependency treatment.

       SECTION 12.08 EARLY CHILDHOOD INTERVENTION (ECI).




                                 Page 52 of 77
<PAGE>   53

       (a)    ECI Services.

       CONTRACTOR must provide all federally mandated services contained at 34
C.F.R. 303.1, et seq., and 25 TAC Section 621.21 et seq., relating to
identification and referral for health care services contained in the Member's
Individual Family Service Plan (IFSP). An IFSP is the written plan which: (1)
identifies a Member's disability or chronic or complex condition(s) or
developmental delay; (2) describes the course of action developed to meet those
needs; and (3) identifies the person or persons responsible for each action in
the plan. The plan is a mutual agreement of the Member's PCP, case manager, and
the Member/family, and is part of the Member's medical record.

       (b)    Identification and Referral.

       CONTRACTOR must ensure that network providers are educated regarding the
identification of Members under age 3 who have or are at risk for having
disabilities and/or developmental delays. CONTRACTOR must use written education
material developed or approved by the Texas Interagency Council on Early
Childhood Intervention. CONTRACTOR must ensure that all providers refer
identified Members to ECI service providers within two business days from the
day the Member is identified. Eligibility for ECI services is determined by the
local ECI program using the criteria contained in 25 T.A.C. Section 621.21, et
seq.

       (c)    Intervention.

       CONTRACTOR must require, through contract provisions, that all medically
necessary Covered Services contained in the Member's IFSP are provided to the
Member in amount, duration and scope established by the IFSP. Medical necessity
for health and behavioral health care services is determined by the
interdisciplinary team as approved by the Member's PCP. CONTRACTOR cannot modify
the plan of care or alter the amount, duration and scope of services required by
the Member's IFSP. CONTRACTOR cannot create unnecessary barriers for the Member
to obtain IFSP services, including requiring prior authorization for the ECI
assessment and insufficient authorization periods for prior authorized services.


                          ARTICLE 13. MEMBER SERVICES


       SECTION 13.01 MEMBER EDUCATION.

       CONTRACTOR must, at a minimum, develop and implement health education
initiatives that educate Members about:

              (a)    How the HMO system operates;

              (b)    How to obtain services, including:

                     (1)    Accessing OB/GYN and plan requirements concerning
                     specialty care;

                     (2)    Emergency services;

                     (3)    Behavioral health care services;



                                 Page 53 of 77
<PAGE>   54

                     (4)    Prenatal services and unique aspects of
                     CHIP/Medicaid eligibility prior- and post-partum;

                     (5)    Care and treatment, under CONTRACTOR's plan, for
                     Members with disabilities and Children with Complex,
                     Special Health Care Needs; and

                     (6)    Early Childhood Intervention (ECI) Services;

              (c)    Covered Services, limitations and any Value-added Services
              offered by CONTRACTOR;

              (d)    Member co-payments, if applicable; and

              (e)    The value of screening and preventive care.

       CONTRACTOR also must provide child-oriented, disease specific-information
and educational materials to Members.

       In addition to the above requirements, CONTRACTOR must make any
additional educational initiatives outlined in its Proposal appropriately
available to Members.

       CONTRACTOR may respond to inquiries from pregnant Members or their
families regarding their potential Medicaid eligibility and making an informed
choice. CONTRACTOR's presentation should be balanced, presenting and explaining
the advantages and disadvantages to the Member of both CHIP and Medicaid as
appropriate in response to the Member's inquiries.


       SECTION 13.02 MEMBER MATERIALS.

       CONTRACTOR must design, print, and distribute Member identification (ID)
cards, provider directories, and evidence of coverage or Member handbooks
detailing Covered and any Value-added Services and the complaint and appeals
process as set out in section 13.06 of this Agreement.

       (a)    Member Handbook.

       Except as noted below, CONTRACTOR must submit to HHSC a Member handbook
that complies with 28 T.A.C. Section 11.1600(b).

              (1)    Exceptions to Section 11.1600(b) requirements.

              Readability. The Member handbook should have a 6th grade reading
              level as measured by the appropriate score on the Flesch reading
              ease test.

              Cost-sharing. The Member handbook section regarding cost-sharing
              should illustrate the variations in Member financial
              responsibility by income levels.

              Provider Directory. CONTRACTOR need not mail a provider directory
              along with the member handbook to individuals at the time of their
              enrollment with CONTRACTOR's health plan. The Texas Department of
              Insurance has approved this exception to 28 TAC Section 11.1600.
              The Administrative Services Contractor will send CONTRACTOR's
              provider directory to an individual after the individual's program
              application is approved. This section does not preclude


                                 Page 54 of 77
<PAGE>   55


              CONTRACTOR from mailing a provider directory to CONTRACTOR's
              Members.

              (2)    Additional requirements.

              Cultural competency. The Member handbook must be available in a
              format accessible to the visually-impaired. The accessible format
              may include large print, Braille, and audio tapes.

              Languages other than English. The Member handbook must be
              available in English, Spanish, and the languages of other major
              population groups making up 10% or more of the enrolled CHIP
              population within the CHIP Service Area, as specified by HHSC.
              HHSC will provide CONTRACTOR with reasonable notice when the
              enrolled CHIP population reaches 10% within the CONTRACTOR's CSA.

       (b)    Evidence of Coverage.

       CONTRACTOR's evidence of coverage must be approved by HHSC and TDI and
comply with applicable Texas insurance law and regulation.

       (c)    Provider Directory.

       The font in the provider directory must be no more or less than 10 points
in height and lowercase unspaced alphabet length of no more or less than 120
points. The weight of the provider directory cannot exceed three (3) ounces. The
provider directory cannot measure larger than 8 1/2" by 11" and the content of
the directory is limited to:

       1.     listing of all network providers, their locations, phone numbers
and office hours, with the exception of specialty providers, who may be listed
by name and location, which may be by county, and by a complete alphabetical
list; and

       2.     two pages (1-page front and back) introducing the plan to the
prospective Member.

       The introduction of the plan to the prospective Member must be at a 6th
grade reading level, as measured by the appropriate score on the Flesch reading
ease test, and must be available in Spanish, English, and the languages of other
major population groups making up 10% or more of the enrolled CHIP population
within the CHIP Service Area, as specified by HHSC. HHSC will provide CONTRACTOR
with reasonable notice when the enrolled CHIP population reaches 10% within the
CONTRACTOR's CSA. The provider directory must be available in a format
accessible to the visually-impaired. The accessible format may include large
print, Braille, and audio tapes.

       (d)    HHSC review of Member material.

       HHSC has 15 business days from the date the Member material is received
to review the submitted material and to recommend any suggestions or required
changes. If HHSC has not responded to CONTRACTOR by the fifteenth day,

<PAGE>   74

impose or pursue one or more remedies for each item of noncompliance and will

identified in CONTRACTOR's Proposal, the RFP, or this Agreement must improve
within thirty (30) days of written notice from HHSC regarding the deficiency.

material delay in the implementation or operation of the CHIP health plan
coverage through HMOs. CONTRACTOR will, within five (5) business days of receipt
of written notice of a non-material deficiency, provide HHSC with a written
response that:

              (A)    Explains the reasons for the deficiency, CONTRACTOR's plan
              to address or cure the deficiency, and the date and time by which
              the deficiency will be cured; or

              (B)    If CONTRACTOR disagrees with HHSC's findings, its reasons

to the approval of HHSC. CONTRACTOR's repeated commission of non-material
deficiencies or repeated failure to resolve any such deficiencies may be
regarded by HHSC as a material deficiency and entitle HHSC to pursue any other
remedy provided in this Agreement or any other appropriate remedy HHSC may have
at law or equity.

       (c)    Notice and opportunity to cure.

specified time period will result in HHSC pursuing an additional remedy or
remedies, including, but not limited to, additional damages and/or termination

       failure to report efforts and compliance as required in section 15.04;

       (2)    CONTRACTOR's placing the health and safety of the Members in
       jeopardy;

       (3)    Exclusion of the CONTRACTOR or any of the managing employees or

       Section 1124(a) of the Social Security Act from the Medicaid or Medicare
       program under the provisions of Section 1128(a) and/or (b) of the Social

       Medicaid or Medicare program under the provisions of Section 1128(a)
       and/or (b) of the Social Security if the exclusion will materially affect
       the CONTRACTOR's performance under this Agreement; and

       (5)    A CONTRACTOR'S failure to report potential or suspected fraud or

       (e)    Corrective Action Plan.

       (1)    In the event HHSC assesses a liquidated damage as provided in this
article, HHSC may require CONTRACTOR to submit to HHSC a detailed written plan
(the "Corrective Action Plan") to correct or resolve the deficiency or event
causing the assessment of the liquidated damage. The Corrective Action Plan must
provide a detailed explanation of the reasons for the cited deficiency,
CONTRACTOR's assessment or diagnosis of the cause, and a specific proposal to
cure or resolve the deficiency. The Corrective Action Plan must be submitted
within ten (10) business days following the request for the plan by HHSC and is
subject to approval by HHSC, which approval will not unreasonably be withheld.

       (2)    Notwithstanding the submission and acceptance of a Corrective
Action Plan, CONTRACTOR remains responsible for achieving all written
performance criteria. The acceptance of a Corrective Action Plan under this
section will not excuse prior substandard performance, relieve CONTRACTOR of its
duty to comply with performance standards, or prohibit HHSC from assessing
additional liquidated damages or pursuing other appropriate remedies for
continued substandard performance.

       (f)    Additional remedies.

       HHSC at its own discretion may impose one or more the following remedies
for each item of noncompliance and will determine the scope and severity of the
remedy on a case-by-case basis. Both Parties agree that a state or federal
statute, rule, regulation or federal guideline will prevail over the provisions
of this section unless the statute, rule, regulation, or guidelines can be read
together with this section to give effect to both.

       (1)    Assess liquidated damages in accordance with section 20.03 and
       deduct such damages against payments to CONTRACTOR as set-off in
       accordance with section 20.04;

       (2)    Conduct accelerated monitoring of CONTRACTOR. Accelerated
       monitoring means more frequent or more extensive monitoring will be
       performed by HHSC than would routinely be accomplished;

       (3)    Require additional, more detailed, financial and/or programmatic
       reports to be submitted by CONTRACTOR in accordance with Article 17 of
       this Agreement; or

       (4)    Suspend new enrollment.

                     (a)    HHSC must give the CONTRACTOR 30 days notice of
                     intent to suspend new enrollment other than for imminent
                     danger to the health or safety of Members. The suspension
                     date will be calculated as 30 days following the date that
                     the CONTRACTOR receives the notice of intent to suspend new
                     enrollment.

                     (b)    HHSC may immediately suspend new enrollment into the
                     CONTRACTOR for a default declared as a result of imminent
                     danger to the health and safety of Members.

                     (c)    The suspension of new enrollment may be for any
                     duration, up to the termination date of the Agreement. HHSC
                     will base the duration of the suspension upon the type and
                     severity of the default and upon the CONTRACTOR's ability,
                     if any, to cure the default.


                                 Page 76 of 77
<PAGE>   77

              (5)    Decline to renew this Agreement.

       HHSC will formally notify CONTRACTOR of the imposition of an
administrative remedy in writing in accordance with paragraph (b) of this
section, with the exception of accelerated monitoring, which may be unannounced.
CONTRACTOR is required to file a written response to in accordance with
paragraph (b) of this section.

              (g)    Informal review of administrative remedies.

       CONTRACTOR may request an informal review of the imposition of the
foregoing remedies in accordance with section 20.16 within ten (10) business
days of receipt of written notification of the imposition of a remedy by HHSC.

       SECTION 20.03 LIQUIDATED DAMAGES.

       The liquidated damages prescribed in this section are not intended to be
in the nature of a penalty, but are intended to be reasonable estimates of
HHSC's projected financial loss and damage resulting from CONTRACTOR's
non-performance, including financial loss as a result of project delays.

       The Parties intend to negotiate liquidated damages specifically tailored
for particular events of non-performance, which schedule will be attached to
this Agreement through amendment. In the event that the Parties fail to reach
agreement on the liquidated damages to be assessed, the events on which they are
to be assessed, or the amount of the damages, the liquidated damages set out in
this section will apply.

       Accordingly, in the event CONTRACTOR fails to perform in accordance with
this Agreement, HHSC may assess liquidated damages as provided in this section.

       (a)    Failure to provide contracted services or support.

       If CONTRACTOR fails to perform any of the Services described in this
Agreement, HHSC may assess a liquidated damage of $1,000.00 each business day
such Service is not provided.

              (1)    Maximum damages.

       Liquidated damages assessed pursuant to this paragraph shall not, in any
single month, exceed 25% of the fee due CONTRACTOR for that month. However, if
CONTRACTOR fails to perform any Service or combination of Services, and such
failure represents a budgeted sum greater than 25% of the fee due CONTRACTOR for
that month, HHSC may terminate the Agreement in accordance with this article.

              (2)    CONTRACTOR responsibility for associated costs.

       If HHSC terminates this Agreement pursuant to paragraph (a)(i) of this
section, CONTRACTOR will be responsible to HHSC for all costs incurred by HHSC,
the State of Texas or any of its administrative agencies to replace CONTRACTOR.
These costs include, but are not limited to, the costs of procuring a substitute
vendor following termination of this Agreement and the cost of any claim or
litigation that is reasonably attributable to CONTRACTOR's failure



                                 Page 77 of 77
<PAGE>   78


to perform any Service in accordance with the Agreement.


       SECTION 20.04 METHOD OF COLLECTION.

       HHSC may elect to assess a liquidated damage directly to CONTRACTOR, or
it may deduct amounts assessed as liquidated damages as set-off against payments
then due to CONTRACTOR for the Services or Deliverables or which become due at
any time thereafter.


       SECTION 20.05 MODIFICATION OF AGREEMENT IN THE EVENT OF REMEDIES.

       As provided in section 8.01(b) of this Agreement, HHSC may propose a
modification of this Agreement in response to the imposition of a remedy under
this article. Any modifications under this section must be reasonable, limited
to the matters causing the exercise of a remedy, and in writing. CONTRACTOR must
negotiate such proposed modifications in good faith.


       SECTION 20.06 TERMINATION OF AGREEMENT.

       In addition to other provisions of this article allowing termination,
this Agreement will terminate upon the Expiration Date unless extended in
accordance with Article 4 of this Agreement, or terminated sooner under the
terms of section 20.07 through section 20.09 of this Agreement. Prior to
completion of the Initial Term and any extensions or renewal thereof, all or a
part of this Agreement may be terminated for any of the following reasons:


       SECTION 20.07 TERMINATION BY MUTUAL AGREEMENT OF THE PARTIES.

       This Agreement may be terminated by mutual agreement of the Parties. Such
agreement must be in writing.

       SECTION 20.08 TERMINATION FOR CAUSE.

       HHSC reserves the right to terminate this Agreement, in whole or in part,
upon the following conditions:

       (a)    Assignment for the benefit of creditors, appointment of receiver,
       or inability to pay debts.

       HHSC may terminate this Agreement if CONTRACTOR:

              (1)    Makes an assignment for the benefit of its creditors;

              (2)    Admits in writing its inability to pay its debts generally
              as they become due; or

              (3)    Consents to the appointment of a receiver, trustee, or
              liquidator of CONTRACTOR or of all or any part of its property.

       (b)    Judgment and execution.

       (1)    HHSC may terminate this Agreement if judgment for the payment of
money in excess of $50,000.00 (fifty thousand dollars and zero cents) which is
not covered by insurance is rendered


                                 Page 78 of 77
<PAGE>   79


by any court or governmental body against CONTRACTOR, and CONTRACTOR does not

              (i)    Discharge the judgment or provide for its discharge in
              accordance with the terms of the judgment;

              (ii)   Procure a stay of execution thereof within 30 days from the
              date of entry thereof; or

              (iii)  Perfect an appeal of such judgment and cause the execution
              of such judgment to be stayed during the appeal, providing such
              financial reserves as may be required under generally accepted
              accounting principles.

       (2)    If a writ or warrant of attachment or any similar process is
issued by any court against all or any material portion of the property of
CONTRACTOR, and such writ or warrant of attachment or any similar process is not
released or bonded within 30 days after its entry, HHSC may terminate this
Agreement in accordance with this section.

       (c)    Failure to adhere to laws, rules, ordinances, or orders.

       HHSC may terminate this Agreement if a court of competent jurisdiction
finds CONTRACTOR failed to adhere to any laws, ordinances, rules, regulations or
orders of any public authority having jurisdiction and such violation prevents
or substantially impairs performance of CONTRACTOR's duties under this
Agreement.

       (d)    Breach of confidentiality.

       HHSC may terminate this Agreement if CONTRACTOR breaches confidentiality
laws with respect to the Services provided under this Agreement.

       (e)    Failure to maintain adequate personnel or resources.

       HHSC may terminate this Agreement if, after providing notice and an
opportunity to correct in accordance with section 20.02 of this Agreement, HHSC
determines that CONTRACTOR has either failed to provide the personnel and
resources described in its Proposal or has failed to supply personnel or
resources and such failure results in CONTRACTOR's inability to fulfill its
duties under this Agreement and substantially compromises HHSC's ability to
comply with legislative mandates regarding the implementation or administration
of CHIP.

       (f)    Termination for insolvency.

       (1)    HHSC may, by giving written notice of termination to CONTRACTOR,
terminate this Agreement as of a date specified in such notice of termination if
CONTRACTOR:

              (A)    files for bankruptcy;

              (B)    becomes or is declared insolvent, or is the subject of any
              proceedings related to its liquidation, insolvency or the
              appointment of a receiver or similar officer for it;

              (C)    makes an assignment for the benefit of all or substantially
              all of its creditors; or

              (D)    enters into a contract for the composition, extension, or
              readjustment of substantially all of its


                                 Page 79 of 77
<PAGE>   80


              obligations.

       (2)    CONTRACTOR agrees to pay for all reasonable expenses of HHSC
including the cost of counsel, incident to:

              (A)    The enforcement of payment of all obligations of CONTRACTOR
              by any action or participation in, or in connection with a case or
              proceeding under chapters 7, 11, or 13 of the United States
              Bankruptcy Code, or any successor statute;

              (B)    A case or proceeding involving a receiver or other similar
              officer duly appointed to handle CONTRACTOR's business; or

              (C)    A case or proceeding in a State court initiated by HHSC
              when previous collection attempts have been unsuccessful.

       (g)    Termination for gifts and gratuities.

       (1)    HHSC may terminate this Agreement on one (1) days' notice to
CONTRACTOR following the determination by a competent judicial or quasi-judicial
authority and CONTRACTOR's exhaustion of all legal remedies that CONTRACTOR, its
employees, agents or representatives have either offered or given any thing of
value an officer or employee of HHSC or the State of Texas in violation of state
law.

       (2)    CONTRACTOR must include a similar provision in each of its
subcontracts and shall enforce this provision against a subcontractor who has
offered or given any thing of value to any of the persons or entities described
in this section, whether or not the offer or gift was in CONTRACTOR's behalf.


       SECTION 20.09 TERMINATION FOR NON-APPROPRIATION OF FUNDS.

       (a)    Notwithstanding any other provision of this Agreement, if funds
for the continued fulfillment of this Agreement by HHSC are at any time not
forthcoming or are insufficient, through failure of any entity to appropriate
funds or otherwise, then HHSC will have the right to terminate this Agreement at
no additional cost and with no penalty whatsoever by giving prior written notice
documenting the lack of funding.

       (b)    In such instance, unless otherwise agreed to by the Parties, this
Agreement will terminate and become null and void on the last day of the fiscal
period for which appropriations were received. HHSC will use all reasonable
efforts to ensure appropriated funds are available.


       SECTION 20.10 TERMINATION IN THE EVENT OF HHSC's FAILURE TO PAY.

       CONTRACTOR may terminate this Agreement if HHSC fails to pay the
CONTRACTOR undisputed charges when due as required under this Agreement.
Retaining premium, recoupment, sanctions, or penalties that are allowed under
this Agreement or that result from the CONTRACTOR's failure to perform or the
CONTRACTOR's default under the terms of this Agreement is not cause for
termination. Termination for failure to pay does not release HHSC from the
obligation to pay undisputed charges for services provided prior to the
termination date.


                                 Page 80 of 77
<PAGE>   81


       CONTRACTOR must give HHSC 90 days written notice of intent to terminate
this Agreement. The termination date will be calculated as the last day of the
month following 90 days from the date the notice of intent to terminate is
received by HHSC.

       HHSC must be given 30 days from the date HHSC receives the CONTRACTOR's
written notice of intent to terminate for failure to pay to pay the CONTRACTOR
all undisputed amounts due. If HHSC pays all undisputed amounts then due within
this 30-day period, the CONTRACTOR cannot terminate the Agreement under this
article for that reason.


       SECTION 20.11 TERMINATION FOR HHSC's MATERIAL BREACH OF THIS AGREEMENT.

       (a)    Generally.

       HHSC's failure to perform a material duty or responsibility as set out in
this Agreement is a default under this Agreement.

       (b)    Notice of default and opportunity to cure.

       CONTRACTOR will provide HHSC with written notice of default (Notice of
Default) under this Agreement. The Notice of Default may be given by any means
that provides verification of receipt. The Notice of Default must contain the
following information:

       1.     A clear and concise statement of the circumstances or conditions
       that CONTRACTOR contends constitute a default under this Agreement;

       2.     The Agreement provision(s) under which CONTRACTOR is declaring a
       default; and

       3.     A statement that HHSC has thirty (30) days from the date HHSC
       receives the Notice of Default to cure the alleged breach.


       SECTION 20.12 NOTICE OF TERMINATION.

       Each Party will provide written notice of termination of this Agreement
at least 90 days prior to the intended date of termination unless the health or
safety of the Members is at issue, in which case HHSC may terminate immediately.


       SECTION 20.13 EXTENSION OF TERMINATION EFFECTIVE DATE.

       HHSC may extend the effective date of termination one or more times as it
elects, in its sole discretion, provided that the total of all such extensions
shall not exceed 90 calendar days following the original effective date of
termination, excluding termination under section 20.11.


       SECTION 20.14 INJUNCTIVE RELIEF.

       Each Party acknowledges and agrees that, in the event of a breach or
threatened breach of any of the provisions of this Agreement, such Party may
have no adequate remedy in damages. Accordingly, each Party will be entitled to
seek an injunction to prevent such breach or threatened breach. However, the
specification of a particular legal or equitable remedy will not


                                 Page 81 of 77
<PAGE>   82

be construed as a waiver, prohibition, or limitation of any other legal or
equitable remedies in the event of a breach of this Agreement.


       SECTION 20.15 PAYMENT AND OTHER PROVISIONS AT AGREEMENT TERMINATION.

       (a)    If HHSC terminates this Agreement, HHSC will pay CONTRACTOR on the
effective date of termination (or as soon as possible thereafter taking into
account appropriation and fund accounting requirements) any undisputed amounts
due for all completed, approved, and accepted Services or Deliverables.

       (b)    HHSC further agrees to negotiate in good faith with CONTRACTOR to
equitably adjust and settle any accrued or outstanding liabilities for any
unaccepted Service or deliverable and Change Order that

              (1)    Is due or delivered prior to or upon contract termination;

              (2)    Is complete or substantially complete, or for which
              CONTRACTOR can document to the satisfaction of HHSC substantial
              progress; and

              (3)    Benefits HHSC or the State of Texas, notwithstanding its
              unaccepted status.

       (c)    CONTRACTOR must provide HHSC all reasonable access to records,
facilities, and documentation as is required to efficiently and expeditiously
close out the Services under this Agreement.

       (d)    HHSC and the CONTRACTOR must prepare a transition plan, which is
acceptable to and approved by HHSC, to ensure that Members are reassigned to
other plans without interruption of services. That transition plan will be
implemented during the 90-day period between receipt of notice and the
termination date unless termination is the result of HHSC's reasonable belief
that the CONTRACTOR is placing the health or welfare of Members in jeopardy.

       CONTRACTOR must continue to perform Services under the transition plan
until the last day of the month following 90 days from the date of receipt of
notice if the termination is for any reason other than HHSC's reasonable belief
that the CONTRACTOR is placing the health and safety of the Members in jeopardy.
If termination is due to this reason, HHSC may prohibit the CONTRACTOR's further
performance of Services under this Agreement.

       (1)    If HHSC terminates this Agreement for any reason other than
non-appropriation of funds under section 20.10:

              (a)    HHSC is responsible for notifying all Members of the date
              of termination and how Members can continue to receive Covered
              Services;

              (b)    CONTRACTOR is responsible for all expenses related to
              giving notice to Members; and

              (c)    CONTRACTOR is responsible for all expenses incurred by HHSC
              in implementing the transition plan.

       (2)    If the Agreement is terminated by the CONTRACTOR for any reason:


                                 Page 82 of 77
<PAGE>   83

              (a)    HHSC is responsible for notifying all Members of the date
              of termination and how Members can continue to receive Covered
              Services;

              (b)    HHSC is responsible for all expenses related to giving
              notice to Members; and

              (c)    HHSC is responsible for all expenses it incurs in
              implementing the transition plan.

       (3)    If the Agreement is terminated by mutual agreement of the Parties
under section 20.07:

              (a)    HHSC is responsible for notifying all Members of the date
              of termination and how Members can continue to receive Covered
              Services;

              (b)    CONTRACTOR is responsible for all expenses related to
              giving notice to Members; and

              (c)    HHSC is responsible for all expenses it incurs in
              implementing the transition plan.


       SECTION 20.16 DISPUTE RESOLUTION.

       (a)    General agreement of the Parties.

       The Parties mutually agree that the interests of fairness, efficiency,
and good business practices are best served when the Parties employ all
reasonable and informal means to resolve any dispute under this Agreement. The
Parties express their mutual commitment to using all reasonable and informal
means of resolving disputes including, but not limited to, the informal review
of liquidated damage assessments under section 20.02 of this Agreement, prior to
invoking a remedy provided elsewhere in this section.

       (b)    Duty to negotiate in good faith.

       Any dispute that in the judgment of any Party to this Agreement may
materially or substantially affect the performance of any Party will be reduced
to writing and delivered to the other Party. The Parties must then negotiate in
good faith and use every reasonable effort to resolve such dispute and the
Parties shall not resort to any formal proceedings unless they have reasonably
determined that a negotiated resolution is not possible. The resolution of any
dispute disposed of by agreement between the Parties shall be reduced to writing
and delivered to all Parties within ten (10) business days.

       (c)    Claims for breach of Agreement.

       (1)    General requirement. As required by Chapter 2260, Government Code,
CONTRACTOR's claim for breach of this Agreement must resolved in accordance with
the dispute resolution process established by HHSC in accordance with Chapter
2260, Government Code.

       (2)    Negotiation of claims. A CONTRACTOR's claim for breach of this
Agreement that the Parties cannot resolve in the ordinary course of business or
through the use of all reasonable and informal means must be submitted to the
negotiation process provided in Chapter 2260, subchapter B, Government Code.

              (A)    To initiate the process, CONTRACTOR must submit written
              notice in accordance with


                                 Page 83 of 77
<PAGE>   84

              Section 4.04 of this Agreement that specifically states that
              CONTRACTOR invokes the provisions of Chapter 2260, subchapter B,
              Government Code.

              (B)    Compliance by CONTRACTOR with Chapter 2260, subchapter B,
              Government Code, is a condition precedent to the filing of a
              contested case proceeding under Chapter 2260, subchapter C, of the
              Government Code.

       (3)    Contested case proceedings. The contested case process provided in
Chapter 2260, subchapter C, Government Code, is CONTRACTOR's sole and exclusive
process for seeking a remedy for any and all alleged breaches of contract by
HHSC if the Parties are unable to resolve their disputes under subsection (d)(2)
of this section.

              (A)    Compliance with the contested case process provided in
              Chapter 2260, Subchapter C, Government Code, is a condition
              precedent to seeking consent to sue from the Texas Legislature
              under Chapter 107, Civil Practices & Remedies Code. Neither the
              execution of this Agreement by HHSC nor any other conduct of any
              representative of HHSC relating to this Agreement shall be
              considered a waiver of the State's sovereign immunity to suit.

       (4)    HHSC rules. The submission, processing and resolution of
CONTRACTOR's claim is governed by the rules to be adopted by HHSC pursuant to
