Aetna shall pay Spinco the amount specified in or calculated in accordance with
the method applicable to such Service as set forth on SCHEDULE 12 (the "PRICING
SCHEDULE"). For any Service priced on a monthly basis, the monthly charge will

first calendar day or the last calendar day, respectively, of a calendar month.
Unless otherwise indicated on a Schedule, all pricing listed on the Pricing
Schedule is applicable to the period from the commencement of such Service
through the end of calendar year 2001 only. It is the intent of the parties
hereto that no party shall realize a gain or a loss as a result of the provision
of Services under this Agreement through the end of 2001. Thereafter, the prices
may increase as indicated in Section 2.02 (b), below.

     (b) PRICE INCREASES. For Services continuing for a period after December
31, 2001, on January 1, 2002 and on each January 1 thereafter during the term
hereof, the prices listed on the Pricing Schedule shall be adjusted based upon
the actual cost for Services plus such additional charges (excluding, however,
those services for which such additional charges are prohibited by law) as are
reasonable and customary in the respective service industry for the
administration of such services (excluding, however, any profit to Spinco).

     (c)  SALES TAX.

          (i) For state and local sales tax purposes, Spinco and Aetna will
     cooperate in good faith to segregate amounts payable under this Agreement
     into the following categories: (a) taxable Services; (b) non-taxable
     Services; and (c) payments made by Spinco merely as a payment agent for
     Aetna in procuring goods, supplies or Services that otherwise are
     non-taxable or that have previously been subject to sales tax.

          (ii) Spinco shall collect from Aetna all state and local sales tax and
     shall timely remit such taxes to the appropriate state and local tax
     authorities. Aetna shall pay such taxes to Spinco monthly, or as otherwise
     required by Spinco. Spinco shall be responsible for any interest or
     penalties imposed as a result of its failure to timely collect and remit
     taxes. Aetna shall be responsible for any additional taxes, interest or
     penalties imposed as a result of a sales tax audit by any taxing authority.

     parking lots pursuant to its lease with Aetna Life Insurance Company dated
     December 13, 2000.

     against service levels.

          (iii) If Aetna becomes aware of a material deficiency in Spinco's
delivery of Services (a "SERVICE LEVEL BREACH"), Aetna may deliver a written
notice thereof to Spinco. Upon receipt of such notice, Spinco shall use
reasonable efforts to remedy the Service Level Breach as soon as possible.

          (iv) Except to the extent that a schedule to this Agreement specifies
     a different period, if Spinco fails to cure a Service Level Breach within

     shall forfeit (and, if previously collected from Aetna, refund) the fees or
     charges otherwise due with respect to such Service from the date that the
     Service Level Breach commenced, and Spinco shall not be entitled to collect
     fees with respect to such Service until it has cured such Service Level
     Breach. The remedy for a Service Level Breach provided under this Section
     2.03(a)(iv) shall be the sole remedy available to Aetna for a Service Level
     Breach.

     (b) PERSONNEL. Spinco, in its sole discretion, will either: (i) employ and
retain staff, (ii) contract with third party subcontractors and other vendors,
or (iii) utilize any combination thereof as needed to perform the Services
Spinco is obligated to perform hereunder. Any such personnel shall have a level
of experience, skill, diligence and expertise consistent with Spinco's normal
business practices. The delegation of performance to a subcontractor shall not
relieve Spinco of any of its duties or obligations under this Agreement.

     Section 2.04. BILLING AND CASH SETTLEMENT PROCEDURES; DEFAULT.

     except as otherwise indicated on the Schedules. Each Service provider shall

     to identify the Services that are the subject of any such bills. Spinco and
     Aetna shall settle amounts so due within fourteen (14) calendar days
     following the receipt of a monthly bill in good order and supported by


                                       8


     proper documentation. Any billing or payment errors shall be corrected
     promptly after discovery thereof.

     (b) PAYROLL REIMBURSEMENTS. On each payroll issue date, Aetna shall
reimburse Spinco for amounts Spinco (i) paid or will pay to Aetna Group (as
defined in the Transition Services Agreement dated the date hereof by and
between Aetna Inc. and Aetna U.S. Healthcare Inc. [the "TSA"]) employees on such
payroll issue date and (ii) withheld or will withhold from such employees
earnings and paid on their behalf to Governmental Entities (as defined in the
TSA), benefit providers or other third parties. Aetna shall reimburse Spinco by
wire transfer of immediately available funds on the same Business Day it
receives advice from Spinco of any amounts that Spinco has paid on behalf of
Aetna for medical/dental premiums or claims (or on the following Business Day if
such advice is received after 9:00 a.m., Eastern time). VENDOR REIMBURSEMENTS.

the prior five (5) business days to vendors on Aetna's behalf. Aetna shall
reimburse Spinco for such amount by wire transfer of immediately available
funds. Each reimbursement shall be due the Friday of the week during which
Spinco advises Aetna of the reimbursement amount (or on the following business
day if such advice is received after 5:00 p.m., Eastern time on the immediately
preceding business day or if such Friday is not a business day). In addition to
the remedy specified below in Section 2.04(e), Aetna shall reimburse Spinco for
any costs incurred arising from Aetna's failure to timely reimburse Spinco.

     (c) REIMBURSEMENT NOTICE FORM OF SETTLEMENT. Reimbursement notices shall be
communicated to Aetna via fax to: 770-933-3664 (Immediate Attention: ING
Treasury). Settlement for amounts due under this Section 2.04 shall be made by
wire transfer of immediately available funds. If any amount remains unsettled
after the date when due, such amount shall bear interest at the 90-Day Treasury
Rate from the date due until the full settlement thereof. The "90-Day Treasury
Rate" means the annual yield rate, as of any given date, of actively traded U.S.
Treasury securities having a remaining duration to maturity of three months, as
such rate is published under "Treasury Constant Maturities" in Federal Reserve
Statistical Release H.l5(5.19).

     (d) DEFAULT IN PAYMENT. If payment for Services is not made within thirty
(30) days of the date when due, then Spinco, upon delivery of written notice to
Aetna, may suspend any such Services until Aetna has cured such payment default.

     any third party's computer systems, software, information and/or data to
     which they are provided access and/or use in connection with this Agreement
     and (b) take such other actions and execute such additional documentation
     required by any vendor in order to access and/or use such vendor's software
     in connection with such vendor's contracts with Spinco.

     (b) LIMITATION OF REMEDIES. Except if and to the extent arising out of
     Spinco's gross


                                       10


     negligence or willful misconduct, in no event shall Spinco be obligated to
     pay to Aetna in respect of breaches or alleged breaches of this Agreement
     any amount in excess of the amount received by Spinco for the Services it
     renders. This cumulative limitation shall apply to all monetary remedies
     provided for in this Agreement or any Schedule thereto, regardless of
     whether they are characterized as damages, indemnification (including,
     without limitation, indemnification for defense costs), refund of fees or
     otherwise.

          (c) HOME OFFICE MOVES. Having moved three hundred seven (307)

     equally (50/50) the costs of any moves beyond this number that are directly
     attributable to the separation.
