         SECTION 4.01. SPINCO INDEMNIFICATION OF AETNA GROUP. (a) Subject to
Section 4.03, from and after the Distribution Date, Spinco shall indemnify,
defend and hold harmless each member of the Aetna Group, their Affiliates

directors and employees (each, an "AETNA INDEMNITEE") from and against any and
all Damages incurred or suffered by any Aetna Indemnitee arising out of (i) any
and all Spinco Group Liabilities or (ii) the breach by any member of the Spinco
Group of any obligation under any Distribution Document (subject to any
limitation set forth therein), other than the Tax Sharing Agreement (all
indemnities thereunder being governed by the specific terms of the Tax Sharing
Agreement).

          (b) Subject to Section 4.03, from and after the Distribution Date,
Spinco shall indemnify, defend and hold harmless each Aetna Indemnitee and each
Person, if any, who controls any Aetna Indemnitee within the meaning of either

<PAGE>

Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all Damages caused by any untrue statement or alleged untrue
statement of a material fact contained in the Form 10 or any amendment thereof
or the Information Statement or Proxy Statement (in each case as amended or
supplemented if Spinco shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, except to the extent
that those Damages are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information that is furnished to
Spinco by Parent or any of its Affiliates (other than any member of the Aetna
Group) specifically for use therein.

         SECTION 4.02. AETNA INDEMNIFICATION OF SPINCO GROUP. (a) Subject to
Section 4.03, from and after the Distribution Date, Aetna shall indemnify,
defend and hold harmless each member of the Spinco Group, their Affiliates and
their respective officers, directors and employees (each, a "SPINCO INDEMNITEE")
from and against any and all Damages incurred or suffered by any Spinco
Indemnitee arising out of (i) any and all Aetna Group Liabilities or (ii) the
breach by any member of the Aetna Group of any obligation under any Distribution
Document (subject to any limitation set forth therein), other than the Tax
Sharing Agreement (all indemnities thereunder being governed by the specific
terms of the Tax Sharing Agreement).

          (b) Subject to Section 4.03, from and after the Distribution Date,
Aetna shall indemnify, defend and hold harmless each Spinco Indemnitee and each
Person, if any, who controls any Spinco Indemnitee within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all Damages caused by any untrue statement or alleged untrue
statement of a material fact contained in the Form 10 or any amendment thereof
or the Information Statement or Proxy Statement (in each case as amended or
supplemented if Spinco shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, in each case to the
extent, but only to the extent, that those Damages are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information that is furnished to Spinco by Parent or any of its Affiliates
(other than any member of the Aetna Group) specifically for use therein.

         SECTION 4.03. INSURANCE AND THIRD PARTY OBLIGATIONS; LIMITATION ON
LIABILITY. (a) Upon indemnification of the Indemnified Party (as defined below),
the Indemnifying Party shall be subrogated to the rights of the Indemnified
Party against any insurer or other third party with respect to such indemnified
amount. It is expressly agreed that no insurer or any other third party shall be
(i) entitled to a benefit it would not be entitled to receive in the absence of
the foregoing

<PAGE>

indemnification provisions, (ii) relieved of the responsibility to pay any
Insured Claims or any other claims to which it is obligated or (iii) entitled to
any subrogation rights with respect to any obligation hereunder.

          (b) Each party shall use its reasonable best efforts to mitigate its
Damages and not to cause or worsen any Liability which would be a Liability of
the other party. If an Indemnified Party shall receive any amount of Insurance
Proceeds or any other amount from a third party in connection with a specific
Liability giving rise to indemnification hereunder (i) at any time subsequent to
the actual receipt of payment in full indemnification of such Liability
hereunder, then such Indemnified Party shall reimburse the Indemnifying Party
for any such indemnification payment made up to the amount of such Insurance
Proceeds or other amounts actually received or (ii) at any time prior to the
receipt of payment in full indemnification of such Liability hereunder, then the
indemnification to be paid under Section 4.01 or 4.02 shall be paid net of the
amount of any such Insurance Proceeds or other amounts actually received (with
such reimbursement as may be required to give effect to such netting).
Notwithstanding this Section 4.03, (x) in no event shall any Indemnified Party
be required (i) to take any action, or forebear from exercising any right, under
the Merger Agreement or any Distribution Document or (ii) to take any action
with respect to, make any demand under or claim any coverage in connection with,
any Policy, and (y) nothing herein shall permit any Indemnifying Party to delay
or refrain from making any payment to any Indemnified Party because of the
availability or alleged availability of any Policy or Insurance Proceeds
(provided that the foregoing shall not limit the subrogation rights of an
Indemnifying Party under Section 4.03(a)).

         SECTION 4.04. NOTICE AND PAYMENT OF CLAIMS. If any Aetna Indemnitee or
Spinco Indemnitee (the "INDEMNIFIED PARTY") determines that it is or may be
entitled to indemnification by any party (the "INDEMNIFYING PARTY") under this
Article 4 (other than in connection with any Action subject to Section 4.05),
the Indemnified Party shall deliver to the Indemnifying Party a written notice
specifying, to the extent reasonably practicable, the basis for its claim for
indemnification and the amount for which the Indemnified Party reasonably
believes it is entitled to be indemnified. Within 30 calendar days after receipt
of such notice, the Indemnifying Party shall pay the Indemnified Party such
amount in cash or other immediately available funds unless the Indemnifying
Party objects in writing to the claim for indemnification or the amount thereof.
In the event of such an objection or failure to pay by the Indemnifying Party,
the amount, if any, that is Finally Determined to be required to be paid by the
Indemnifying Party in respect of such indemnity claim shall be paid by the
Indemnifying Party to the Indemnified Party in cash within 15 calendar days
after such indemnity claim has been so Finally Determined, with interest thereon
at the prime rate of Citibank N.A. in effect from time to time for the period
commencing on the 30th day following receipt of the initial notice of the claim
from the Indemnified Party until

<PAGE>

the date of actual payment (inclusive).

         SECTION 4.05. NOTICE AND DEFENSE OF THIRD-PARTY CLAIMS. (a) Promptly
(and in any event within 10 Business Days) following the earlier of (i) receipt
of notice, whether by service of process or otherwise, of the commencement by a
third party of any Action against or otherwise involving any Indemnified Party
or (ii) receipt of information from a third party alleging the existence of a
claim against an Indemnified Party, in either case, with respect to which
indemnification may be sought pursuant to this Agreement (a "THIRD-PARTY
CLAIM"), the Indemnified Party shall give the Indemnifying Party written notice
thereof. The failure of the Indemnified Party to give notice as provided in this
Section 4.05 shall not relieve the Indemnifying Party of its obligations under
this Agreement, except to the extent that the Indemnifying Party is actually and
materially prejudiced by such failure to give notice.

          (b) Within 30 calendar days after receipt of notice from the
Indemnified Party pursuant to Section 4.05(a), the Indemnifying Party may (by
giving written notice thereof to the Indemnified Party) elect at its option to,
and shall at the request of the Indemnified Party, assume the defense of such
Third-Party Claim at the Indemnifying Party's sole cost and expense unless the
Indemnifying Party objects in writing to such indemnification claim (in which
case the Indemnified Party may not require the Indemnifying Party to assume the
defense and the Indemnifying Party shall only assume the defense with the
consent of the Indemnified Party). During such 30-calendar day period, unless
and until the Indemnifying Party assumes the defense of a Third-Party Claim or
objects in writing, the Indemnified Party shall take such action as it deems
appropriate, acting in good faith, in connection with the Third-Party Claim;
PROVIDED, however, that the Indemnified Party shall not settle or compromise, or
make any offer to settle or compromise, the Third-Party Claim without the prior
written consent of the Indemnifying Party (which shall not be unreasonably
withheld).

          (c) If the Indemnifying Party assumes the defense of a Third-Party
Claim, (w) it shall keep the Indemnified Party timely informed of all
significant developments in connection therewith, (x) the defense shall be
conducted by counsel retained by the Indemnifying Party, PROVIDED that the
Indemnified Party shall have the right to participate in such proceedings and to
be represented by counsel of its own choosing at the Indemnified Party's sole
cost and expense; and (y) the Indemnifying Party may settle or compromise the
Third-Party Claim without the prior written consent of the Indemnified Party so
long as such settlement or compromise includes an unconditional release of the
Indemnified Party from all claims that are the subject of such Third-Party
Claim, PROVIDED that the Indemnifying Party may not agree to any such settlement
or compromise pursuant to which there is any finding or admission of any
violation of Law or pursuant to which any remedy or relief (including but not
limited to the imposition of a consent order, injunction or decree which would
restrict the future activity or

<PAGE>

conduct of the Indemnified Party or any Subsidiary or Affiliate thereof), other
than monetary damages for which the Indemnifying Party shall be responsible
hereunder, shall be applied to or against the Indemnified Party, without the
prior written consent of the Indemnified Party (which shall not be unreasonably
withheld).

          (d) If the Indemnifying Party has not objected in writing to such
indemnification claim, and, if at the end of the 30-calendar day period referred
to in Section 4.05(b) the Indemnifying Party has not assumed the defense of such
Third-Party Claim, or, if earlier, beginning at such time as the Indemnifying
Party has declined in writing to assume the defense of a Third-Party Claim, (x)
the Indemnified Party will take such steps as it deems appropriate to defend
that Third-Party Claim and the defense shall be conducted by counsel retained by
the Indemnified Party, PROVIDED that the Indemnifying Party shall have the right
to participate in such proceedings and to be represented by counsel of its own
choosing at the Indemnifying Party's sole cost and expense; and (y) the
Indemnifying Party shall reimburse the Indemnified Party on a current basis (and
in any event within 30-calendar days after the submission of invoices and bills
by an Indemnified Party) for its expenses of investigation, attorneys' and
expert witnesses' fees and other out-of-pocket expenses incurred in defending
against such Third-Party Claim and the Indemnifying Party shall be bound by the
result obtained with respect thereto by the Indemnified Party; PROVIDED further,
that the Indemnified Party shall not settle or compromise, or make any offer to
settle or compromise, the Third-Party Claim without the prior written consent of
the Indemnifying Party (which shall not be unreasonably withheld).

          (e) The Indemnifying Party shall pay to (or at the direction of) the
Indemnified Party in cash the amount, if any, for which the Indemnified Party is
entitled to be indemnified hereunder within 15 calendar days after such
Third-Party Claim has been Finally Determined, in the case of an indemnity claim
as to which the Indemnifying Party has acknowledged liability or, in the case of
any indemnity claim as to which the Indemnifying Party has not acknowledged
liability, within 15 calendar days after such Indemnifying Party's liability, if
any, hereunder has been Finally Determined.

          (f) Notwithstanding any other provision of this Agreement, Aetna
acknowledges and agrees that Spinco shall (solely at its own cost and expense)
assume and continue the defense of all the Spinco Litigation and that, as long
as such settlement or compromise includes an unconditional release of all Aetna
Indemnitees, Spinco shall be permitted to settle or compromise such Actions
without the consent of Aetna or any of its Affiliates; PROVIDED that Spinco may
not agree to any such settlement or compromise pursuant to which there is any
finding or admission of any violation of Law or pursuant to which any remedy or
relief (including but not limited to the imposition of a consent order,
injunction or decree which would restrict the future activity or conduct of the
Aetna Indemnitees), other than monetary damages for which Spinco shall be
responsible

<PAGE>

hereunder, shall be applied to or against such Aetna Indemnitee, without the
prior written consent of such Aetna Indemnitee (which shall not be unreasonably
withheld); PROVIDED, FURTHER, that Spinco shall use its reasonable best efforts
to defend any Aetna Indemnitee and to cause any Aetna Indemnitee to be dismissed
with prejudice as a party to any pending or future Spinco Litigation and, to the
extent any Aetna Indemnitee believes, in its reasonable judgment, that Spinco
has failed to diligently pursue such defense or dismissal, the Aetna Indemnitee
shall be entitled (at its own cost and expense) to independently move for or
otherwise pursue such defense or dismissal and to take such related actions as
it may deem necessary or appropriate in connection therewith. Spinco shall keep
Aetna timely informed of all significant developments with respect to the Spinco
Litigation to which any Aetna Indemnitee is a party.

          (g) Subject to Article 6, each party shall cooperate, and cause their
respective Representatives to cooperate, in the defense or prosecution of any
Third-Party Claim and shall furnish or cause to be furnished such records,
information and testimony, and attend such conferences, discovery proceedings,
hearings, trials or appeals, as may be reasonably requested in connection
therewith.

         SECTION 4.06. NON-EXCLUSIVITY OF REMEDIES. The remedies provided for in
this Article 4 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to any Indemnified Party at law or in equity.
If the indemnification provided for in this Article 4 is unavailable to any
Indemnified Party (x) that is a member of the Aetna Group on the grounds that
such Indemnified Party was a former Affiliate of Spinco or (y) on other public
policy grounds, then the Indemnifying Party shall pay to the Indemnified Party's
parent such amount that represents the diminution in value to such parent as a
result of the Indemnifying Party's inability to so indemnify such Indemnified
Party (PROVIDED that such amount shall not exceed the amount that would
otherwise have been payable by the Indemnifying Party to such Indemnified Party
in respect of such claim pursuant to this Article 4).

                                    ARTICLE 5
                    EMPLOYEE MATTERS AND TRANSITION SERVICES

         SECTION 5.01. EMPLOYEE MATTERS GENERALLY. With respect to employee
matters and employee benefits arrangements, the parties hereto agree as set
forth herein and in the Employee Benefits Agreement and in the Tax Sharing
Agreement.

         SECTION 5.02. OTHER MATTERS GENERALLY. With respect to the provision of
certain services by either Group to the other Group after the Distribution Time
and other matters, the parties hereto agree as set forth herein and in the
Transition Services Agreement, the CityPlace Agreements, the Lease Agreement,
the Real
<PAGE>

Estate Services Agreement, the VDC Agreement, the Policy Cancellation
Agreement, the Software Licensing Agreement, the 10 State House Square Services
Agreement, the Information Technology Closing Agreement and the Assignment of
Letters Patent.

                                    ARTICLE 6
                              ACCESS TO INFORMATION

         SECTION 6.01. PROVISION OF CORPORATE RECORDS. Except as otherwise
specifically set forth in this Agreement or any Ancillary Agreement, immediately
prior to or as soon as practicable following the Distribution Date, each Group
shall provide to the other Group all documents, Contracts, books, records and
data (including but not limited to minute books, stock registers, stock
certificates and documents of title) in its possession relating primarily to the
other Group or its business, assets and affairs (after giving effect to the
transactions contemplated hereby); PROVIDED that if any such documents,
Contracts, books, records or data relate to both Groups or the business and
operations of both Groups, each such Group shall provide to the other Group true
and complete copies of such documents, Contracts, books, records or data. Data
stored in electronic form shall be provided in the format in which it existed at
the Distribution Date, except as otherwise specifically set forth in this
Agreement or any Ancillary Agreement.

         SECTION 6.02. ACCESS TO INFORMATION. From and after the Distribution
Date, each Group shall, for a reasonable period of time, afford promptly to the
other Group and its accountants, counsel and other designated Representatives
reasonable access during normal business hours to all documents, Contracts,
books, records, computer data and other data in such Group's possession relating
to such other Group or the business and affairs of such other Group (after
giving effect to the transactions contemplated hereby) (other than data and
information that is (i) specifically not subject to the provisions of this
Article 6 or (ii) subject to, in the case of access provisions in any joint
defense arrangements between a member or members of one Group and a member or
members of the other Group, the terms of the relevant joint defense agreement),
insofar as such access is reasonably required by such other Group, including,
without limitation, for audit, accounting, litigation, regulatory compliance and
disclosure and reporting purposes.

         SECTION 6.03. LITIGATION COOPERATION. From and after the Distribution
Date: (a) Each Group shall use all reasonable best efforts to make available to
the other Group and its accountants, counsel, and other designated
representatives, upon written request, its current and former directors,
officers, employees and representatives as witnesses, and shall otherwise
cooperate with the other Group, to the extent reasonably required in connection
with any Action or threatened

<PAGE>

Action arising out of either Group's business and operations in which the
requesting party may from time to time be involved.

          (b) Each party hereto shall promptly notify the other party hereto,
upon its receipt or the receipt by any of its Affiliates, of a request or
requirement (by oral questions, interrogatories, requests for information or
documents, subpoenas, civil investigative demands or other similar processes)
which relates to the business and operations of the other party (a "REQUEST")
reasonably regarded as calling for the inspection or production of any documents
or other information in its possession, custody or control, as received from any
Person that is a party in any Action, or in the event the Person delivering the
Request is not a party to such Action, as received from such Person. In addition
to complying with the applicable provisions of Section 6.06, each party shall
assert and maintain, or cause its Affiliates to assert and maintain, any
applicable claim to privilege, immunity, confidentiality or protection in order
to protect such documents and other information from disclosure, and shall seek
to condition any disclosure which may be required on such protective terms as
may be appropriate. No party may waive, undermine or fail to take any action
necessary to preserve an applicable privilege without the prior written consent
of the affected party hereto (or any affected Affiliate or Affiliates of any
such party) except, in the opinion of such party's counsel, as required by law.

          (c) Aetna, on its own behalf and on behalf of all of its Affiliates,
hereby waives any conflict which might preclude counsel currently representing
Aetna, Spinco or any of their respective Affiliates from representing Spinco
and/or any of its Affiliates following the Distribution Date in connection with
the Spinco Litigation existing at the Merger Effective Time.

          (d) Aetna and Spinco shall enter into such joint defense agreements,
in customary form, as Aetna and Spinco shall determine are advisable.

         SECTION 6.04. REIMBURSEMENT. Except to the extent that any member of
one Group is obligated to indemnify any member of the other Group under Article
4 for that cost or expense, each Group providing information or witnesses to the
other Group, or otherwise incurring any expense in connection with cooperating,
under Sections 6.01, 6.02 or 6.03 shall be entitled to receive from the
recipient thereof, upon the presentation of invoices therefor, payment for all
out-of-pocket costs and expenses that may be incurred in providing such
information, witnesses or cooperation.

         SECTION 6.05. RETENTION OF RECORDS. From and after the Distribution
Date, except as otherwise required by law or agreed to in writing, each party
shall, and shall cause the members of its respective Group to, retain all
information relating to the other Group's business and operations in accordance
with the then general practice of such party with respect to information
relating to its own business and operations. Notwithstanding the foregoing, any
party may destroy or otherwise

<PAGE>

dispose of any such information at any time, PROVIDED that, prior to such
destruction or disposal, (i) such party shall provide not less than 90 calendar
days' prior written notice to the other party, specifying the information
proposed to be destroyed or disposed of and the scheduled date for such
destruction or disposal, and (ii) if the recipient of such notice shall request
in writing prior to the scheduled date for such destruction or disposal that any
of the information proposed to be destroyed or disposed of be delivered to such
requesting party, the party proposing the destruction or disposal shall promptly
arrange for the delivery of such of the information as was requested at the
expense of the requesting party.

         SECTION 6.06. CONFIDENTIALITY. From and after the Distribution Date,
each party shall hold and shall cause its Affiliates and their respective
directors, officers, employees, counsel, accountants, agents, consultants,
advisors and other authorized representatives ("REPRESENTATIVES") to hold in
strict confidence, and not misuse, all documents and other information (other
than any such documents and other information relating solely to the business or
affairs of such party) concerning the other party and/or its Affiliates
("CONFIDENTIAL INFORMATION"), unless such party is compelled to disclose such
documents and/or other information by judicial or administrative process or, in
the opinion of its counsel, by other requirements of law or the rules of any
applicable stock exchange. Confidential Information shall not include such
documents and/or other information which can be shown to have been (A) in the
public domain through no fault of such party, (B) lawfully acquired after the
Distribution Date on a non-confidential basis from other sources or (C) acquired
or developed independently by such party without violating this Section 6.06 or
the Confidentiality Agreement. Notwithstanding the foregoing, such party may
disclose such Confidential Information to its Representatives so long as such
Persons are informed by such party of the confidential nature of such
Confidential Information and are directed by such party to treat such documents
and/or other information confidentially. In the event that such party or any of
its Representatives is requested or required (by oral questions,
interrogatories, requests for information or documents, subpoenas, civil
investigative demands or other similar processes) to disclose any of the
Confidential Information, such party will promptly notify the other party so
that the other party may seek a protective order or other remedy or waive such
party's compliance with this Section 6.06. Such party shall exercise reasonable
best efforts to preserve the confidentiality of the Confidential Information,
including, but not limited to, by cooperating with the other party to obtain an
appropriate protective order or other reliable assurance that confidential
treatment will be accorded the Confidential Information. If, in the absence of a
protective order or other remedy or the absence of receipt of a waiver of the
other party, such party or any of its Representatives is nonetheless legally
compelled to disclose any of the Confidential Information, such party or such
Representative may disclose only that portion of the Confidential Information
which is legally required to be disclosed. Each party agrees to be responsible
for any breach of

<PAGE>

this Section 6.06 by it and/or its Representatives.

         SECTION 6.07. PRESERVATION OF PRIVILEGE. The parties hereto recognize
that as a consequence of the transactions contemplated by this Agreement or the
Merger Agreement or the Ancillary Agreements, the parties may have common
interests in the defense of certain pending or threatened litigation which may
necessitate the exchange between the parties or their counsel of documents or
other information that is subject to the attorney-client privilege, the work
product doctrine or other legally recognized privileges, protections or
immunities from discovery. Each party agrees to take in addition to, and not in
limitation of, its obligations under Section 6.03(b) all reasonable best and
necessary efforts to protect and maintain, and to cause its Affiliates to
protect and maintain, any applicable claim to privilege, immunity, protection or
confidentiality in order to protect such documents and other information from
improper disclosure or use. In addition to, and not in limitation of, its
obligations under Section 6.03(b) and without limiting the generality of the
foregoing, and to the maximum extent permitted by law, none of the parties or
their respective Affiliates may waive or undermine, or fail to defend in a
commercially reasonable manner, any privilege or protection or take or fail to
take any other commercially reasonable action (a) that could result in the
disclosure of any common-interest or joint-defense materials to any Person that
is neither a party to this Agreement nor an Affiliate of any such party or (b)
that would have the effect of waiving or undermining such privilege or
protection, in either case, without the prior written consent of the affected
party and any affected Affiliate of such affected party.

         SECTION 6.08. INAPPLICABILITY OF ARTICLE 6 TO TAX MATTERS.
Notwithstanding anything to the contrary in this Article 6, this Article 6 shall
not apply with respect to documents, other information and/or other matters
relating to Taxes, all of which shall be governed by the Tax Sharing Agreement.

                                    ARTICLE 7
                            CERTAIN OTHER AGREEMENTS

         SECTION 7.01. INTERCOMPANY ACCOUNTS. (a) Except as otherwise
specifically set forth herein or in any of the Ancillary Agreements or in the
Merger Agreement, (i) all intercompany loan balances in existence as of the
Distribution Time between any member of the Aetna Group and any member of the
Spinco Group will be settled or paid in cash or other immediately available
funds prior to or as of the Distribution Time and (ii) all intercompany accounts
receivable and accounts payable between any member of one Group and any member
of another Group in existence at the Distribution Time shall be paid in full, in
cash or other immediately available funds, by the party or parties owing such
obligations as

<PAGE>

soon as practicable (but in no event more than 30 calendar days after the
Distribution Time). It is understood and agreed that all or a portion of the
intercompany loan balances owed by Spinco to Aetna Services will be paid in cash
by Spinco.

          (b) At or prior to the Distribution Time, Aetna shall repay or cause
to be repaid all Short Term Debt of any member of the Aetna Group, other than
(i) not more than $17.4 million aggregate principal amount (together with
accrued and unpaid interest thereon) of Short Term Debt issued by Cruz Blanca
S.A., AFP Santa Maria S.A., Aetna Credito Hipotecario S.A., and Aetna Life
Insurance Company of America, Taiwan Branch, and (ii) any Short Term Debt of any
Person that is not a Subsidiary of Aetna.

          (c) Except as otherwise contemplated hereby or as set forth on
Schedule 7.01 or in any of the other Distribution Documents or in the Merger
Agreement, all prior agreements and arrangements, including those relating to
goods, rights or services provided or licensed, between any member of the Spinco
Group and any member of the Aetna Group are hereby terminated effective as of
the Distribution Time, if not previously terminated and Aetna and Spinco shall
cause each of their Subsidiaries to take those actions that may be necessary to
cause such termination and take such further actions (including executing any
documents as may be necessary to terminate and void (including retroactively)
any amendment to the agreements listed on Schedule 7.01 entered into since the
date of the Merger Agreement to which Parent does not consent) as may be
reasonably requested by the other party to effect the foregoing. No such
agreements or arrangements shall be in effect after the Distribution Time unless
embodied in this Agreement, the Distribution Documents or set forth on Schedule
7.01.

         SECTION 7.02. TRADEMARKS; TRADE NAMES. (a) Prior to the Distribution
Time, Aetna and Spinco will enter into the Trademark Assignment Agreements, the
Chinese Mark Agreement and the Trademark Licensing Agreement.

          (b) From and after the Distribution Date, (i) Aetna will not, and will
not permit any of its Affiliates to, use any of (A) the Licensed Marks and
Names, except as specifically permitted by the Trademark Licensing Agreement,
and (B) the Spinco Group's logos, marks or names (other than the Licensed Marks
and Names), and (ii) Spinco will not, and will not permit any of its Affiliates
to, use the Aetna China Name Rights except as specifically permitted by the
Chinese Mark Agreement.

          (c) From and after the Distribution Date, Spinco will not, and will
not permit any of its Affiliates to, infringe upon the Aeltus Name Rights.

          (d) As promptly as practicable following the Distribution Time, Aetna
will file with the applicable Governmental Entity amendments to its articles or
certificate of incorporation and, except as otherwise provided under the Chinese
Mark Agreement, otherwise take all action necessary to delete from its name the
word "Aetna" or any marks and names derived therefrom, and shall do or cause to

<PAGE>

be done all other acts, including the payment of any fees required in connection
therewith, to cause such amendments or other actions to become effective. Aetna
will cause all other members of the Aetna Group to take the foregoing actions
with respect to the names of the Aetna Subsidiaries as promptly as practicable
prior to the end of the Permitted Trademark Period.

          (e) From and after the Distribution Date, each party agrees to
cooperate with the other party in connection with any regulatory matters
relating to the Trademark Licensing Agreement, the Chinese Mark Agreement and
the Trademark Assignment Agreements, subject to the terms of each such
agreement.

          (f) Aetna acknowledges that from and after the Distribution Date,
notwithstanding the use of the marks and names (the "LICENSED MARKS AND NAMES")
licensed by Spinco as licensor pursuant to the Trademark Licensing Agreement,
the Aetna Name Rights will remain an asset of the Spinco Group and shall include
any goodwill associated with the use of the "Aetna" name, and any derivative
thereof, in combination with one or more of the Acquiror's existing names or
marks as permitted by the Trademark Licensing Agreement.

         SECTION 7.03. FURTHER ASSURANCES AND CONSENTS. In addition to the
actions specifically provided for elsewhere in this Agreement, each of the
parties hereto shall use its reasonable best efforts to take, or cause to be
taken, all actions, and to do, or cause to be done, all things, reasonably
necessary, proper or advisable under applicable laws, regulations and agreements
or otherwise to consummate and make effective the transactions contemplated by
this Agreement, including, without limitation, using its reasonable best efforts
to obtain any consents and approvals and to make any filings and applications
necessary or desirable in order to consummate the transactions contemplated by
this Agreement; PROVIDED that no party hereto shall be obligated to pay any
consideration therefor (except for filing fees and other similar charges) to any
third party from whom such consents or approvals are requested or to take any
action or omit to take any action if the taking of or the omission to take such
action would be unreasonably burdensome to the party, its Group or its Group's
business. The parties agree to enter into and execute such additional
Distribution Documents as may be reasonably necessary, proper or advisable to
effect the transactions contemplated by this Agreement or the Ancillary
Agreements, PROVIDED, however that such additional Distribution Documents shall
not diminish any of the rights granted or increase any of the Liabilities
assumed under this Agreement or the Ancillary Agreements.

         SECTION 7.04. NONCOMPETITION AND NON-SOLICITATION. (a)(i) For a period
of three (3) years following the Merger Effective Time, neither Spinco nor any
of its Affiliates (after giving effect to the Distribution) will engage in the
following businesses conducted by the Aetna Group immediately prior to the
Merger Effective Time: (A) in the United States, underwriting and/or issuance of
defined contribution group annuities for pension plans maintained by employer or
similar groups pursuant to Section 401(k), 403(b) or 457 of the U.S. Internal
Revenue Code of 1986, as amended (or any successor law), underwriting and/or
issuance of

<PAGE>

individual annuities, providing investment advisory or broker-dealer
services, or the management of mutual funds, and (B) in those jurisdictions
outside of the United States listed in Schedule 7.04(a)(I), those businesses
specified with respect to each such jurisdiction ((A) and (B) collectively, the
"Prohibited Businesses"), and (i) for an additional period of 12 months, to the
extent that Spinco or any of its Affiliates (after giving effect to the
Distribution) engages directly or indirectly in any Prohibited Business, it will
do so using a brand other than "Aetna" (except and only to such extent as may be
required by Law); PROVIDED that the foregoing shall not prohibit Spinco or any
of its Affiliates from (x) conducting any of the activities set forth in
Schedule 7.04(a)(II), (y) engaging in any Prohibited Business in any
jurisdiction specified in Schedule 7.04(a) if the Aetna Group ceases to engage
in such business in such jurisdiction, or (z) owning, acquiring or investing in
any Person, PROVIDED that if such Person derives in excess of 10% of its
consolidated gross revenue in the most recently completed four fiscal quarters
from business activities which would be restricted hereunder, Spinco will, or
will cause such Affiliate to, divest a portion of such business representing
such excess within 12 months of the acquisition date (unless, in the case of the
restriction specified in (i) above, such 12-month period would terminate
subsequent to the termination of the 3-year restriction period). It is
understood that the restrictions set forth in the immediately preceding sentence
will not apply to any Person that acquires (by acquisition, merger or otherwise)
an interest in Spinco or any of its Affiliates so long as such Person was not an
Affiliate of Spinco that was subject to such restrictions prior to the
aforementioned acquisition, merger or other acquisitive transaction (it being
further understood that, following the aforementioned acquisition, merger or
other acquisitive transaction, such restrictions will continue to apply to
Spinco and its Affiliates that were subject to such restrictions prior to such
acquisition, merger or other transaction).

          (b) Except as otherwise specifically permitted by any Ancillary
Agreement, for a period of two years from the Merger Effective Date, neither
Group nor any of its Affiliates shall, directly or indirectly, solicit or
attempt to employ or employ any employee of the other Group. Notwithstanding the
foregoing, the restriction set forth in the immediately preceding sentence shall
not apply to (i) with respect to all employees other than officers and other
senior management of any member of a Group, any Person who contacts such Group
or any of its Affiliates in response to general advertisements or searches or
other broad-based hiring methods or (ii) individuals who choose to leave for
Good Reason the employment of, or are terminated by, a Group without the other
Group having taken any action otherwise prohibited by this Section 7.04(b).
"GOOD REASON" for the purposes of this Section 7.04(b) shall mean a significant
or long-term reduction in compensation, a relocation of more than 50 miles from
the employee's current place of employment or a material diminution of the
employee's duties and responsibilities.
<PAGE>

         (c) If any provision contained in this Section 7.04 shall for any
reason be held invalid, illegal or unenforceable in any respect, such
invalidity, illegality or unenforceability shall not affect any other provisions
of this Section, but this Section shall be construed as if such invalid, illegal
or unenforceable provision had never been contained herein. It is the intention
of the parties that if any of the restrictions or covenants contained herein is
held to cover a geographic area or to be for a length of time which is not
permitted by applicable law, or in any way construed to be too broad or to any
extent invalid, such provision shall not be construed to be null, void and of no
effect, but to the extent such provision would be valid or enforceable under
applicable law, a court of competent jurisdiction shall construe and interpret
or reform this Section to provide for a covenant having the maximum enforceable
geographic area, time period and other provisions (not greater than those
contained herein) as shall be valid and enforceable under such applicable law.
In addition to and not in limitation of the parties' obligations under Section
8.14, each of the parties hereto acknowledges that the other party would be
irreparably harmed by any breach of this Section and that there would be no
adequate remedy at law or in damages to compensate such party for any such
breach. Each of the parties hereto agrees that the other party shall be entitled
to injunctive relief requiring specific performance by such party of this
Section, and consents to the entry thereof.

         SECTION 7.05. THIRD PARTY BENEFICIARIES. Acquiror and Parent shall be
third party beneficiaries of this Agreement. Except as contemplated in the
preceding sentence, nothing contained in this Agreement is intended to confer
upon any Person or entity other than the parties hereto and their respective
successors and permitted assigns and Acquiror and Parent, any benefit, right or
remedies under or by reason of this Agreement, except that the provisions of
Article 4 shall inure to the benefit of the Spinco Indemnitees and the Aetna
Indemnitees.

         SECTION 7.06. INTELLECTUAL PROPERTY RIGHTS AND LICENSES. Except as
otherwise specifically set forth in this Agreement or in any of the other
Ancillary Agreements, neither Group shall have any right or license in or to any
technology, software, Intellectual Property Right or other proprietary right
owned, licensed or held for use by the other Group.

         SECTION 7.07. INSURANCE. (a) The Spinco Assets shall include any and
all rights of an insured party under each of the Group Policies, subject to
the terms of such Group Policies and any limitations or obligations of Spinco
contemplated by this Section 7.07 or Schedule 7.07, specifically including
rights of indemnity and the right to be defended by or at the expense of the
insurer, with respect to all Actions and Liabilities incurred or claimed to
have been incurred prior to the Distribution Date by any party in or in
connection with the conduct of any of the Spinco Group or the Aetna Group or
their respective businesses and operations,

<PAGE>

and which Actions and Liabilities may arise out of an insured or insurable
occurrence under one or more of such Group Policies. With respect to all of the
applicable Group Policies, Spinco shall use its reasonable best efforts, at its
option, either (x) to cause Aetna and its Affiliates to be named or maintained
as additional insured parties thereunder to the extent of, or (y) to obtain a
run-off or tail coverage policy with respect to, in each case, their respective
insurable interests in respect of the Aetna Group Liabilities incurred or
claimed to have been incurred prior to the Distribution Date and insured
thereunder, and the Aetna Assets shall include such rights, to the extent they
relate to the Aetna Group Liabilities, of an additional insured party under each
such Group Policy or under such run-off or tail policy, as applicable, subject
to the terms of such Policy.

          (b) Spinco shall administer all Group Policies. Where Aetna Group
Liabilities are covered under the Group Policies for periods prior to the
Distribution Date, or under any Group Policy covering claims made after the
Distribution Date with respect to an action, error, omission or occurrence prior
to the Distribution Date, then from and after the Distribution Date, upon
request from Aetna, Spinco shall claim coverage for Insured Claims under such
Group Policy as and to the extent that such insurance is available (subject to
Section 7.07(c)) up to the full extent of the applicable limits of liability of
such Group Policy.

          (c) Spinco shall use its reasonable best efforts to cause Insurance
Proceeds received with respect to claims, costs and expenses under the Group
Policies (i) relating to Aetna Group Liabilities, to be paid directly to Aetna
(or the applicable member of the Aetna Group) and (ii) relating to the Spinco
Group Liabilities to be paid directly to Spinco (or the applicable member of the
Spinco Group). In the event Spinco has been unable to cause Insurance Proceeds
to be paid directly to a Aetna Group member in accordance with the preceding
sentence, or to cause Aetna and its Affiliates to be named or maintained as
additional insureds or to obtain run-off or tail policies in accordance with the
last sentence of Section 7.07(a), Spinco shall inform Aetna of the reasons
therefor and Aetna shall be entitled, at its own cost and expense, to take such
actions as may be necessary to achieve such payment or such additional insured
status or to obtain such run-off or tail policy (so long as such actions are not
materially adverse to Spinco). Payment of the allocable portions of indemnity
costs out of Insurance Proceeds resulting from such Group Policies will be made
by Spinco to the appropriate party upon receipt from the insurance carrier (to
the extent not paid directly to a Aetna Group member pursuant to the first
sentence of this Section 7.01(c)). In the event that the aggregate limits on any
Group Policies are exceeded by the aggregate of outstanding Insured Claims by
the parties hereto, the parties shall agree on an equitable allocation of
Insurance Proceeds based upon their respective bona fide claims. Each party
agrees to use reasonable best efforts to maximize available coverage under those
Group Policies applicable to such

<PAGE>

party, and to take all reasonable steps to recover from all other responsible
parties in respect of an Insured Claim to the extent coverage limits under a
Group Policy have been exceeded or would be exceeded as a result of such Insured
Claim. Notwithstanding any other provision of this Agreement, Spinco shall not
be required to renew, extend or expand the coverage available under any of the
Group Policies PROVIDED, that prior to any termination (or failure to reinstate)
such Group Policies with respect to coverage of any Aetna Group Liabilities
insured thereunder, Spinco shall afford Aetna the opportunity of taking such
commercially reasonable steps as may be necessary to maintain such coverage in
place.

         SECTION 7.08. PROHIBITION ON CERTAIN SALES. Aetna agrees that for one
year from the Merger Effective Time, unless there is a material change at
Acquiror and its Subsidiaries, Aetna will not sell or permit to be sold the
interests of Aetna International, Inc. in Taiwan, Hong Kong and Malaysia;
PROVIDED, that the foregoing shall not limit the right of Aetna to sell minority
interests in such Subsidiaries.

         SECTION 7.09. BRAZILIAN CERTIFICATE OF FOREIGN CAPITAL REGISTRATION.
Prior to the Distribution Date, Aetna shall use its reasonable best efforts to
provide to Parent a copy of the Certificate of Foreign Capital Registration for
Sul America Aetna Seguros e Previdencia S.A., and if not prior to the
Distribution Date, Spinco shall provide such certificate to Parent within one
year from the Distribution Date.

         Any party may, by written notice so delivered to the other parties,
change the address to which delivery of any notice shall thereafter be made.

         SECTION 8.02. AMENDMENTS; NO WAIVERS. (a) Any provision of this
Agreement may be amended or waived if, and only if, such amendment or waiver is
in writing and signed, in the case of an amendment, by Aetna and Spinco, or in

<PAGE>

the case of a waiver, by the party against whom the waiver is to be effective.
In addition, unless the Merger Agreement shall have been terminated in
accordance with its terms, any such amendment or waiver that is adverse in
interest to any member of the Aetna Group shall be subject to the written
consent of Parent.

          (b) No failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

         SECTION 8.03. EXPENSES. (a) All costs and expenses incurred by Aetna or
Spinco in connection with the preparation, execution and delivery of the
Ancillary Agreements and the consummation of the Distribution and the other
transactions contemplated hereby and therein (including the fees and expenses of
all counsel, accountants and financial and other advisors of both Groups in
connection therewith, and all expenses in connection with preparation, filing
and printing of the Form 10, the Information Statement and the Proxy Statement)
shall be paid by Spinco; PROVIDED that the Parent and its Affiliates shall pay
their own expenses, if any, incurred in connection with the Distribution and
Spinco shall pay all Transaction Expenses (as defined in the Merger Agreement),
in each case except as specifically provided otherwise herein, in the Merger
Agreement or any Ancillary Agreement.

          (b) Each reference in this Agreement to expenses, fees and
out-of-pocket costs shall mean such expenses, fees and out-of-pocket costs as
the party incurring such expenses, fees or out-of-pocket costs would reasonably
incur in connection with its own business under circumstances where such
expenses, fees and out-of-pocket costs are not subject to reimbursement.

         SECTION 8.04. SUCCESSORS AND ASSIGNS. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; PROVIDED that neither party may assign,
delegate or otherwise transfer any of its rights or obligations under this
Agreement without the prior written consent of Parent and the other party
hereto. If any party or any of its successors or assigns (i) shall consolidate
with or merge into any other Person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger or (ii) shall transfer all
or substantially all of its properties and assets to any Person, then, and in
each such case, proper provisions shall be made so that the successors and
assigns of such party shall assume all of the obligations of such party under
the Distribution Documents.

         SECTION 8.05. GOVERNING LAW. This Agreement shall be construed in
accordance with and governed by the law of the State of Delaware, without regard
to the conflict of laws rules thereof.
<PAGE>

         SECTION 8.06. COUNTERPARTS; EFFECTIVENESS. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have received
a counterpart hereof signed by the other party hereto.

         SECTION 8.07. ENTIRE AGREEMENT. This Agreement, the Merger Agreement,
the Confidentiality Agreement and the other Distribution Documents constitute
the entire understanding of the parties with respect to the subject matter
hereof and thereof and supersede all prior agreements, understandings and
negotiations, both written and oral, between the parties with respect to the
subject matter hereof and thereof. No representation, inducement, promise,
understanding, condition or warranty not set forth herein or in the
Confidentiality Agreement, the Merger Agreement or the other Distribution
Documents has been made or relied upon by any party hereto. To the extent that
the provisions of this Agreement are inconsistent with the provisions of any
other Ancillary Agreement, the provisions of such other Ancillary Agreement
shall prevail.

         SECTION 8.08. TAX SHARING AGREEMENT; SET-OFF; PAYMENT OF AFTER-TAX
AMOUNTS; CERTAIN TRANSFER TAXES. (a) Except as otherwise specifically provided
herein and not inconsistent with the Tax Sharing Agreement, this Agreement shall
not govern any Tax, and any and all claims, losses, damages, demands, costs,
expenses or liabilities relating to Taxes shall be exclusively governed by the
Tax Sharing Agreement.

          (b) If, at the time Spinco is required to make any payment to Aetna or
any of its Affiliates under this Agreement, Aetna or any of its Affiliates owes
Spinco or any of its Affiliates any amount under this Agreement or any Ancillary
Agreement, then such amounts shall be offset and the excess shall be paid by the
party liable for such excess. Similarly, if at the time Aetna is required to
make any payment to Spinco or any of its Affiliates under this Agreement, and
Spinco or any of its Affiliates owes Aetna or any of its Affiliates any amount
under this Agreement or any Ancillary Agreement, then such amounts shall be
offset and the excess shall be paid by the party liable for such excess.

          (c) If Aetna, Spinco or any of their respective post-Distribution
Affiliates makes a payment pursuant to Section 4.01 or 4.02 of this Agreement,
then such Person shall also pay the recipient of such payment the related
After-Tax Amount (as defined in the Tax Sharing Agreement). This Section 8.08(c)
shall be interpreted in accordance with the principles set forth in the Tax
Sharing Agreement and shall be subject to the dispute resolution provisions
contained in Section 10.09 of the Tax Sharing Agreement.

          (d) Except as otherwise specifically provided in the Ancillary
Agreements, all transfer, documentary, sales, use, stamp and registration taxes
and fees (including any penalties and interest) incurred in connection with any
of the

<PAGE>

transactions described in Article 2 of this Agreement shall be borne and
paid equally by Spinco and Aetna. The party that is required by applicable law
to file any Return (as defined in the Tax Sharing Agreement) or make any payment
with respect to any of those taxes shall do so, and the other party shall
cooperate with respect to that filing or payment as necessary. The non-paying
party shall reimburse the paying party in accordance with this Section 8.08, as
appropriate, within 5 Business Days after it receives notice of the payment of
those taxes. This Section 8.08(d) shall be interpreted in accordance with the
principles set forth in the Tax Sharing Agreement and shall be subject to the
dispute resolution provisions contained in Section 10.09 of the Tax Sharing
Agreement.

         SECTION 8.09. JURISDICTION. Except as otherwise expressly provided in
this Agreement, any Action seeking to enforce any provision of, or based on any
matter arising out of or in connection with, this Agreement or the transactions
contemplated hereby may be brought in the United States District Court for the
District of Delaware, and each of the parties hereby consents to the
jurisdiction of such court (and of the appropriate appellate courts therefrom)
in any such Action and irrevocably waives, to the fullest extent permitted by
law, any objection which it may now or hereafter have to the laying of the venue
of any such Action in any such court or that any such Action which is brought in
any such court has been brought in an inconvenient forum. Process in any such
Action may be served on any party anywhere in the world, whether within or
without the jurisdiction of any such court. Without limiting the foregoing, each
party agrees that service of process on such party as provided in Section 8.01
shall be deemed effective service of process on such party.

         SECTION 8.10. PRE-LITIGATION DISPUTE RESOLUTION. Prior to the bringing
of any Action against the other, senior officers of Aetna and Spinco shall
confer, consult and in good faith attempt for a period of 30 calendar days to
resolve any dispute between such parties relating to this Agreement or any of
the other Distribution Documents (other than the Tax Sharing Agreement) without
resort to legal remedies.

         SECTION 8.11. SEVERABILITY. If any one or more of the provisions
contained in this Agreement should be declared invalid, illegal or unenforceable
in any respect, the validity, legality and enforceability of the remaining
provisions contained in this Agreement shall not in any way be affected or
impaired thereby so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such a declaration, the parties shall modify this Agreement so as to
effect the original intent of the parties as closely as possible in an
acceptable manner so that the transactions contemplated hereby are consummated
as originally contemplated to the fullest extent possible.

<PAGE>

         SECTION 8.12. SURVIVAL. All covenants and agreements of the parties
contained in this Agreement and the Confidentiality Agreement shall survive the
Distribution Date indefinitely, unless a specific survival or other applicable
period is expressly set forth therein.

         SECTION 8.13.  CAPTIONS.  The captions herein are included for
convenience of reference only and shall be ignored in the construction or
interpretation hereof.

         SECTION 8.14. SPECIFIC PERFORMANCE. Each party to this Agreement
acknowledges and agrees that damages for a breach or threatened breach of any of
the provisions of this Agreement would be inadequate and irreparable harm would
occur. In recognition of this fact, each party agrees that, if there is a breach
or threatened breach, in addition to any damages, the other nonbreaching party
to this Agreement, without posting any bond, shall be entitled to seek and
obtain equitable relief in the form of specific performance, temporary
restraining order, temporary or permanent injunction, attachment, or any other
equitable remedy which may then be available to obligate the breaching party (i)
to perform its obligations under this Agreement or (ii) if the breaching party
is unable, for whatever reason, to perform those obligations, to take any other
actions as are necessary, advisable or appropriate to give the other party to
this Agreement the economic effect which comes as close as possible to the
performance of those obligations (including, but not limited to, transferring,
or granting liens on, the assets of the breaching party to secure the
performance by the breaching party of those obligations).

<PAGE>

         IN WITNESS WHEREOF the parties hereto have caused this Distribution
Agreement to be duly executed by their respective authorized officers as of the
date first above written.

for, or be the sponsor of, and ceases to be a "participating employer" in or

         (a) Effective Immediately after the Distribution Date, AI or an AI

2000 amendments to the Severance and Salary Continuation, Benefits Plan, and
also including PTO) made available to such Employees immediately prior to the

New AI Plan to the same extent as if those items occurred under the New AI Plans
specified in (a) above and any other benefit plan, arrangement or policy
applicable after the Distribution Date to AI Employees, except to the extent
that duplication of benefits would result. AUSHC shall provide appropriate data
to AI about such past service.

BONUS PAYMENTS.

         least equal to the amount, if any, by which the AI Stock Value exceeds
         the option exercise price.

         (ii) In connection with the Restructuring and Distribution and
         effective as of the Distribution Date, AI and AUSHC shall cause each
         option to acquire AI Stock held by members of the AUSHC Employee Group
         and by Severed Employees under the AI Equity-Based Plans and all other
         options to acquire AI Stock not subject to Section 2.04(b)(i) to (x) be
         equitably adjusted to reflect the Distribution, (y) converted into an
         option to purchase AUSHC Stock (provided, however, than in no event
         shall such AUSHC options cover more than 45,000,000 shares of AUSHC
         Stock) or the right to receive cash or a similar benefit from AUSHC and
         (z) cease to relate to AI Stock. Each such AUSHC option may continue to
         have and be subject to the same terms and conditions set forth in the
         AI Equity-Based Plans and as provided in the respective option
         agreements governing such AI options as of the Distribution Date.
         Neither AI nor any Affiliate shall have any Liability with respect to
         AUSHC options, AI options or, except as provided in

<PAGE>

         Section 2.04(a), under the AI Equity-Based Plans or the Aetna
         Performance Excellence Unit Plan.

         (c) AI hereby assumes Liability for all annual bonus payments to AI
Employees under the "SCHEDULED BONUS PLANS" (designated as such on Schedule
3) to the extent accrued on the books and records of any AI Company (such
Liabilities, the "AI BONUS LIABILITIES") and any assets allocated to such
Liabilities shall be transferred to AI. AUSHC hereby assumes Liability for
all bonus payments in excess of the AI Bonus Liabilities (including amounts
in excess of amounts so accrued on the books and records of any AI Company
relating to transaction bonus program payments referred to in Section 5.1(f)
of the Company Disclosure Letter provided in connection with the Merger
Agreement and amounts owed to AUSHC Employees), notwithstanding the
foregoing, AUSHC shall have no Liabilities for any bonus payments to AI
Employees in excess of the target bonus amount so accrued for such AI
Employees (such Liabilities, the "AUSHC BONUS LIABILITIES").

                    Savings, Supplemental and Pension Plans

         Section 3.01. THE SAVINGS PLAN.

         (a) (i) AUSHC shall retain all Liabilities and obligations in respect
of benefits accrued by each member of the AI Employee Group under the Savings
Plan until, in the case of AI Employees, such Liabilities are transferred to and
assumed by the DC Plan as described below. Prior to such transfer, AUSHC and AI
shall work together to develop a process whereby AI Employees who have loans
outstanding under the Savings Plan will be permitted to continue to make
periodic repayments on such outstanding loans through a reduction of salary paid
by AI and AI remitting such payments to the Savings Plan on a timely basis
(including AI charging such AI employees a reasonable administrative fee, if
any, for such services).

         (ii) Effective immediately after the Distribution Date, AI or an AI
         ERISA Affiliate shall adopt (in consultation with ING America Insurance
         Holdings, Inc.) a savings plan for the benefit of AI Employees that is
         substantially similar to the Savings Plan and is intended to qualify
         under Section 401(a) of the Code (the "DC PLAN"). For at least twelve
         months after the Distribution Date the DC Plan shall permit deferrals
         and require matching contributions at least equal to those provided
         under the Savings Plan immediately prior to the Distribution Date to
         the extent permissible under applicable law and without altering any
         benefit under any other plan maintained by AI or any AI ERISA
         Affiliate. In one or more transactions in the first calendar year
         beginning after the Distribution Date (provided that (A) AI has
         received a favorable determination letter from the Internal Revenue
         Service to the effect that the DC Plan meets the requirements for
         qualification under Section 401(a) of the Code (or a certification by
         AI, reasonably satisfactory to AUSHC, to such effect), (B) AUSHC has
         received a favorable determination letter from the Internal Revenue
         Service to the effect that

<PAGE>

         the Savings Plan meets the requirements for qualification under Section
         401(a) of the Code (or a certification by AUSHC, reasonably
         satisfactory to AI, to such effect), and (C) the applicable regulatory
         filing requirements have been met) (1) AUSHC shall cause the Savings
         Plan accounts of AI Employees not otherwise rehired by AUSHC after the
         Distribution Date which are held by the Saving Plan's related trust to
         be transferred to the DC Plan and its related trust, and AI shall cause
         those transferred accounts, all of which shall be 100% vested as of the
         Distribution Date, to be accepted by the DC Plan and its related trust
         and (2) the DC Plan shall assume and be solely responsible for
         Liabilities only with respect to transferred accounts of such AI
         Employees (al(ii)abl such assumed liabilities "AI DC PLAN
         LIABILITIES"). Such transfer shall be in-kind to the maximum extent
         practicable and shall not favor participants who are AUSHC Employees
         over participants who are AI Employees; provided, however, that AUSHC
         shall use its reasonable efforts to effect an equitable partition of
         the Stable Value Fund. Any DC Plan fund relating to AUSHC Stock shall
         be administered so as to permit transfers out of, but not additions to,
         such fund.

         (b) After the Distribution Date, AUSHC shall retain all assets and
Liabilities under the Savings Plan except as otherwise provided in Section
3.01(a) ("RETAINED SAVINGS PLAN LIABILITIES").

         Section 3.02. SUPPLEMENTAL PLANS AND DEFERRED COMPENSATION PLANS.

         (a) (i) Effective Immediately after the Distribution Date, all
Liabilities accrued on the books and records of any AI Company with respect to
the Supplemental Plans to the extent applicable to any AI Employee and assets
allocable to such Liabilities, if any, shall be transferred to and assumed by AI
effective as of Immediately after the Distribution Date ("AI SUPPLEMENTAL
LIABILITIES") under the New AI Plans that correspond to the Supplemental Plans.

         (ii) All other Liabilities under the Supplemental Plans are hereby
transferred to and assumed or otherwise retained by AUSHC ("RETAINED
SUPPLEMENTAL LIABILITIES").

         (b) (i) AI hereby assumes and shall be responsible for all deferred
compensation plan Liabilities accrued on the books and records of any AI Company
with respect to any member of the AI Employee Group ("AI DEFERRED COMPENSATION
LIABILITIES") and any assets allocated to such Liabilities shall be transferred
to AI.

         (ii) AUSHC hereby assumes and shall be responsible, for all other
deferred compensation plan Liabilities whenever incurred, accrued in respect of
any member of the AI Employee Group (except as provided in (i)) and in respect
of each AUSHC Employee Group member ("AUSHC DEFERRED COMPENSATION LIABILITIES").

         (iii) AUSHC and AI shall cooperate to ensure that no deferred
compensation amount is distributed prematurely in respect of any AI Employee.

         Section 3.03. PENSION PLAN.

         (a) Subject to completion of the asset transfer specified in Section
3.03(b), effective as of Immediately after the Distribution Date, AI or an AI
ERISA Affiliate shall adopt or become a participating employer in a defined
benefit plan intended to qualify under Section 401(a) of the Code (the "DB
PLAN"), and AI shall designate effective as of the Distribution Date such plan
as a plan for the benefit of AI Employees who immediately prior to the
Distribution Date participated in the Pension Plan and shall cause the DB Plan

<PAGE>

to provide benefits and entitlements as of the Distribution Date and, except
as provided below, for the twelve month period beginning on the Distribution
Date, to such AI Employees which are at least substantially equivalent to the
benefits and entitlements provided to such AI Employee under the Pension Plan
immediately prior to the Distribution Date and under which (x) each such AI
Employee is given credit under the DB Plan for service to the extent
recognized immediately prior to the Distribution Date by the Pension Plan,
for all purposes, including eligibility, vesting, benefit accrual,
eligibility for early retirement, subsidized early retirement and death
benefits, (y) each such AI Employee is given credit under the DB Plan for
service with AI after the Distribution Date for purposes of vesting and early
retirement eligibility in respect of the Transferred Benefits, and (z) each
AI Employee who was a "TRANSITION PARTICIPANT" (as defined in the Pension
Plan) in the Pension Plan on the Distribution Date will have his or her pay
with AI (or an AI ERISA Affiliate) after the Distribution Date recognized
through December 31, 2006 using the Pension Plan's "transition final average
pay" formula in calculating his or her minimum DB Plan benefit. In
calculating a Transition Participant's otherwise applicable DB Plan benefit,
the transition final average pay benefit shall apply as a minimum benefit. If
AI does not recognize service through December 31, 2006 in the DB Plan in
calculating the "transition final average pay" formula minimum benefit for
Specified Participants, then AI will use reasonable efforts to provide, in
the aggregate, the economic equivalent impact of such benefits under the DC
Plan (only taking into account the incremental employer contributions), the
DB Plan and/or such other retirement benefit plans or arrangements as AI may
establish.

         (b) As soon as practicable after the Distribution Date, AUSHC shall
cause to be transferred from the Pension Plan an amount to the DB Plan an
amount in cash or other assets acceptable to AI and the trustee of the DB
Plan at least equal to all accrued benefits and other liabilities of the
Pension Plan relating to AI Employees (the "TRANSFERRED BENEFITS"),
calculated as of the Distribution Date, in the form and manner described
below. Following the completion of the transfer of assets and liabilities
from the Pension Plan to the DB Plan as provided herein, AUSHC and its
Affiliates shall have no further liability whatsoever (either under this
Agreement or otherwise) with respect to such benefits of the AI Employees
under the Pension Plan. As of the Distribution Date, AUSHC shall cause AI
Employees to cease further accrual of benefits under the Pension Plan.

         (i) AUSHC shall cause Hewitt Associates LLC ("AUSHC'S ACTUARY") to
         determine the value of the Transferred Benefits under Section 414(l)
         of the Code as if the Pension Plan were terminated on the Distribution
         Date using the safe harbor assumptions that would be used by the PBGC
         upon plan termination (assuming no ancillary benefits have been
         amended out of the Pension Plan prior to such calculation) except that
         the Pension Plan's actuarial valuation turnover assumptions (as used
         in the Hewitt Associates report dated June 7, 2000) shall be used (the
         "TRANSFER AMOUNT"), but in no event shall such Transfer Amount be less
         than (i) the minimum amount needed to satisfy the requirements of
         Section 414(l) of the Code or (ii) if greater, the projected benefit
         obligation for the AI Employees (as determined under SFAS 87 using the
         same actuarial assumptions and methods used in AI's 2000 financial
         statements), to the extent permitted by Section 414(l) of the Code.

         (ii) The actuarial calculation of the liabilities as well as
         assumptions and

<PAGE>

         methodologies used to calculate such liability underlying the Transfer
         Amount determined by AUSHC's Actuary shall be subject to review and
         challenge by an actuarial firm designated by AI. In the event those two
         actuaries cannot agree, the matter will be sent to a third independent
         actuary for the final determination. Promptly after the Closing Date,
         (provided that (A) AUSHC has received a certification by AI, reasonably
         satisfactory to AUSHC, to the effect that the DB Plan meets the
         requirements for qualification under Section 401(a) of the Code, (B) AI
         has received a certification by AUSHC, reasonably satisfactory to AI,
         to the effect that the Pension Plan meets the requirements for
         qualification under Section 401(a) of the Code, and (C) the applicable
         regulatory filing requirements have been met), AUSHC shall cause to be
         transferred from the trust for the Pension Plan to the trust
         established for the DB Plan, an amount equal to 85% of the amount
         reasonably estimated by AUSHC's Actuary in good faith to be equal to
         the Transfer Amount (the "INITIAL TRANSFER AMOUNT"). As soon as
         practicable after the final determination of the Transfer Amount (the
         "TRUE-UP DATE"), AUSHC shall cause a second transfer to be made to the
         DB Plan, in cash, of the "TRUE-UP AMOUNT". The True-Up Amount shall be
         a positive amount equal to the Transfer Amount minus the sum of (i) the
         Initial Transfer Amount and (ii) distributions, if any, from, and
         reasonable expenses of administration (consistent with past practice)
         under, the Pension Plan for benefits or other purposes made with
         respect to AI Employees from the Closing Date through the True-Up Date
         plus interest on the True-Up Amount at the rate of the 5%, compounded
         annually (the "PLAN RATE") from and including the Closing Date through
         but excluding the True-Up Date or, in the case of distributions
         and reasonable administrative expenses, from and including the Closing
         Date through the date such distribution is made or such expense is
         paid.

         (iii) If for any reason the Initial Transfer Amount exceeds the
         Transfer Amount, then on the True-Up Date or as soon thereafter as
         practicable, AI shall cause the DB Plan to transfer to the Pension Plan
         an amount, in cash, equal to the amount by which the Initial Transfer
         Amount exceeds the Transfer Amount, plus interest thereon from and
         including the Closing Date through but excluding the True-Up Date (or,
         if later, the date on which such amount is transferred to the Pension
         Plan) at the Plan Rate, plus an amount equal to distributions, if any,
         from, and reasonable expenses of administration (consistent with past
         practice) under, the Pension Plan for benefits or other purposes made
         with respect to AI Employees from the Distribution Date through the
         date of such transfer adjusted for interest at the Plan Rate,
         consistent with the approach set forth in (ii) above.

         (c) AUSHC and AI shall cooperate after the Distribution Date so as to
ensure the proper administration of the Pension Plan and the DB Plan.

         (d) Notwithstanding any provision of this Agreement to the contrary, if
at any time before the Distribution Date, the PBGC asserts any issue with
respect to the Pension Plan, AUSHC may, in its sole discretion (i) enter into
negotiations with the PBGC to resolve any such issues and, upon satisfactorily
resolving such issues, AUSHC shall fully comply with the terms of this Article;
(ii) reach such other agreement as may be satisfactory to AI and AUSHC or (iii)
take such actions in lieu of the transfer of assets and liabilities contemplated
above as AUSHC may deem appropriate; provided, however, that any such actions
under this sub-section (iii) shall not have an adverse financial

<PAGE>

impact on ING America Insurance Holdings, Inc. or AI.

                            Health and Welfare Plans

         Section 4.01. ASSUMPTION OF HEALTH AND WELFARE PLAN LIABILITIES;
GENERAL PROVISIONS.

         (a) Effective as of Immediately after the Distribution Date and except
as provided in Section 4.02(a), all Liabilities to or relating to claims
incurred after the Distribution Date by each AI Employee under the "AUSHC HEALTH
AND WELFARE PLANS" (designated as such on Schedule 3 hereto) shall cease to be
Liabilities of the AUSHC Health and Welfare Plans and are hereby transferred to
and assumed by AI as of Immediately after the Distribution Date ("AI HEALTH AND
WELFARE LIABILITIES") under the New AI Plans that correspond to the AUSHC Health
and Welfare Plans (the "NEW AI HEALTH AND WELFARE PLANS" (designated as such on
Schedule 5 hereto)); provided, however, if insured coverage shall have been
purchased for the month by the AI Employee such AUSHC coverage shall continue
until the end of that coverage month. AUSHC hereby retains all other
Liabilities, including claims relating to AI Employees incurred but unreported
prior to the Distribution Date under the AUSHC Health and Welfare Plans ("AUSHC
HEALTH AND WELFARE LIABILITIES").

         (b) Notwithstanding Section 4.01, all treatments which have been
precertified for or are being provided to an AI Employee as of the Distribution
Date, to the extent not provided in a New AI Health and Welfare Plan, shall be
provided without interruption under the appropriate AUSHC Health and Welfare
Plan until such treatment is concluded or discontinued pursuant to applicable
plan rules and limitations (but not beyond December 31, 2001), but AI shall
continue to be responsible for all Liabilities relating to, arising out of or
resulting from such on-going treatments as of the Distribution Date.

         (c) AI shall cause the New AI Health and Welfare Plans to recognize and
maintain all coverage and contribution elections made by AI Employees under the
AUSHC Health and Welfare Plans as of the Distribution Date and apply such
elections under the New AI Health and Welfare Plans for the remainder of the
period or periods for which such elections are by their terms applicable. The
transfer or other movement of employment from AUSHC to AI at any time before the
Close of the Distribution Date shall neither constitute nor be treated as a
"status change" under the AUSHC Health and Welfare Plans or the New AI Health
and Welfare Plans.

         (d) AI shall cause the New AI Health and Welfare Plans to recognize and
give credit for all amounts applied to deductibles, out-of-pocket maximums, and
other applicable benefit coverage limits with respect to which such expenses
have been incurred by AI Employees under the AUSHC Health and Welfare Plans for
the remainder of the year in which the Distribution Date occurs to the extent
recognized under the comparable AUSHC Health and Welfare Plans.

         (e) AI shall provide coverage to AI Employees under the New AI Health
and Welfare Plans without the need to undergo a physical examination or
otherwise provide

<PAGE>

evidence of insurability to the extent recognized under the comparable
AUSHC Health and Welfare Plans.

         (f) AI shall cause the New AI Health and Welfare Plans to recognize and
credit all service of each AI Employee recognized by the corresponding AUSHC
Health and Welfare Plan before the Close of the Distribution Date for all
purposes, including, but not limited to, severance, disability and PTO.

         Section 4.02. POST-RETIREMENT HEALTH AND LIFE INSURANCE BENEFITS.

         (a) (i) AUSHC shall be responsible for providing to AI Employees who
are eligible to receive post-retirement medical or dental or life insurance
coverages under the AUSHC Health and Welfare Plans were they to retire
immediately before the Close of the Distribution Date and to all members of the
AUSHC Employee Group such coverage under the AUSHC Health and Welfare Plans
("RETAINED RETIREE HEALTH AND LIFE LIABILITIES"). Nothing shall prevent AUSHC
from amending or terminating such plans.

         (ii) Any AI Employee who is at least 45 years of age with at least 10
years of credited service and whose credited age and service under AUSHC's
Health and Welfare Plans on the Distribution Date equals 65 ("GROUP 1
EMPLOYEES") shall, if employed by any AI Company during the period ending
December 31, 2001, be eligible for credit thereunder for up to one additional
completed year of service and up to one additional year of attained age, and
further provided that any AI employee who is not a Group 1 Employee and who is
at least 45 years of age with 10 years of credited service under such Plans on
the Distribution Date and who is employed by any AI Company during the period
ending December 31, 2001 shall also be eligible to receive such credit. In each
case, such additional age and service credit shall only be provided through the
earlier of December 31, 2001 and the date such Employee ceases to be employed by
any AI Company. In consideration of the foregoing, immediately after the
Distribution Date AI shall pay to AUSHC an initial payment of $300,000 (the
"Initial Payment"). On January 2, 2002, AI shall pay to AUSHC an additional
payment of $300,000 (the "Final Amount"); provided, however, that solely in the
event that any provision of AUSHC's Health and Welfare Plans relating to Group 1
Employees is amended on or prior to December 31, 2001 in a manner adverse to any
Group 1 Employee, the Final Amount shall be determined as hereinafter provided.
In such case, on or as soon as practicable after December 31, 2001, AUSHC shall
cause AUSHC's Actuary to determine the cost to AUSHC (the "Applicable Cost") of
providing the foregoing credits as of December 31, 2001 under AUSHC's Health and
Welfare Plans as in effect on such date. The actuarial calculation of such cost
liabilities as well as assumptions and methodologies used to calculate such cost
determined by AUSHC's Actuary shall be subject to review and challenge by an
actuarial firm designated by AI. In the event those two actuaries cannot agree,
the matter will be sent to a third independent actuary for the final
determination of the Applicable Cost. The Final Amount shall be the positive
amount by which the Applicable Cost exceeds the Initial Payment. As soon as
practicable after the final determination of the Applicable Cost, AI shall pay
to AUSHC the Final Amount.

         (b) AI shall provide to AI Employees not eligible for coverage pursuant
to sub-section (a) above, post-retirement medical, dental or life insurance
coverages under the New AI Health and Welfare Plans equivalent to coverage
provided to similarly situated employees of ING America Insurance Holdings, Inc.
("AI RETIREE HEALTH AND
<PAGE>

LIFE LIABILITIES") and, except as provided in Section 6.01(b)(v), shall
have no obligations or Liabilities in respect of such medical, dental or life
insurance coverages whether or not assumed by AUSHC.

         Section 4.03. EFFECT OF CHANGE IN RATES. AUSHC and AI shall use their
reasonable efforts to cause each of the insurance companies, HMOs,
point-of-service vendors and third-party administrators providing services and
benefits under the AUSHC Health and Welfare Plans and the New AI Health and
Welfare Plans to maintain the premium and/or administrative rates based on the
aggregate number of participants in both the AUSHC Health and Welfare Plans and
the New AI Health and Welfare Plans through the expiration of the financial fee
or rate guarantees in effect as of the Close of the Distribution Date under the
respective contracts, policies, and agreements separately rated or adjusted for
the demographics, experience or other relevant factors related to the covered
participants of AUSHC and AI, respectively. To the extent they are not
successful in such efforts, AUSHC and AI shall each bear the revised premium or
administrative rates attributable to the individuals covered by their respective
health and welfare plans.

         Section 4.04. COBRA and HIPPA.

         (a) AUSHC shall be responsible for administering compliance with the
health care continuation coverage requirements of COBRA and the AUSHC Health and
Welfare Plans with respect to all members of the AUSHC Employee Group.

         (b) Effective as of Immediately after the Distribution Date, AI shall
solely be responsible for administering compliance with the health care
continuation coverage requirements of COBRA and the New AI Health and Welfare
plans with respect to AI Employees who have a qualifying event within the
meaning of COBRA at any time beginning Immediately after the Distribution Date.

         (c) For periods before the Distribution Date, AUSHC shall be
responsible for administering compliance with the portability requirements under
the Health Insurance Portability and Accountability Act of 1996 with respect to
AI Employees and other employees and former employees of the AI and
beneficiaries and dependents thereof and AI shall be responsible for filing all
necessary employee change notices with respect to AI Employees in accordance
with applicable AUSHC policies and procedures. Effective immediately after the
Distribution Date, AI shall be solely responsible for administering compliance
with such health care continuation coverage and portability requirements with
respect to AI Employees, and AUSHC shall be solely responsible for administering
compliance with such requirements with respect to members of the AUSHC Employee
Group.

         Section 4.05. LEAVE OF ABSENCE PROGRAMS AND FMLA.

         (a) AUSHC shall be responsible for administering compliance with the
AUSHC leave of absence programs and FMLA with respect to each member of the
AUSHC Employee Group.

         (b) Effective as of Immediately after the Distribution Date: (i) AI
shall adopt, and shall cause each AI Company to adopt, leave of absence
programs; (ii) AI shall honor, and shall cause each AI Company to honor, all
terms and conditions of leaves of absence which have been granted to any AI
Employee under an AUSHC leave of absence

<PAGE>

program or FMLA before the Distribution Date by AI, including such leaves that
are to commence after the Distribution Date; (iii) AI and each AI Company shall
be solely responsible for administering leaves of absence and compliance with
FMLA with respect to their employees; and (iv) AI and each AI Company shall
recognize all periods of service of each AI Employee with the Aetna Companies or
any of their Subsidiaries, as applicable, to the extent such service is
recognized by AUSHC for the purpose of eligibility for leave entitlement under
the AUSHC leave of absence programs and FMLA.

         (c) As soon as administratively possible and not later than the
Distribution Date, AUSHC shall provide to AI copies of all records pertaining to
the AUSHC leave of absence programs and FMLA with respect to all AI Employees to
the extent such records have not been provided previously to AI or an AI
Company.

         Section 4.06. AUSHC WORKERS COMPENSATION PROGRAM.

         (a) Effective immediately after the Distribution Date, AI hereby
assumes and shall be responsible for all workers' compensation Liabilities
relating to AI Employees to the extent accrued on the books and records of any
AI Company (the "AI WCP LIABILITIES") and any assets allocated to such
Liabilities shall be transferred to AI.

         (b) Effective immediately after the Distribution Date, AUSHC hereby
assumes and shall be responsible for all workers compensation Liabilities in
respect of members of the AUSHC Employee Group and worker's compensation
Liabilities in respect of AI Employees that are not AI WCP Liabilities, ("AUSHC
WCP LIABILITIES")

         (c) AI and AUSHC shall cooperate with respect to the issuance of new,
or transfer of, existing workers' compensation policies and licenses.

         Section 4.07. FLEXIBLE BENEFIT PLANS.

         (a) To the extent any AI Employee contributed to an account under the
AUSHC Health Care Spending Account Plan ("AUSHC HCSAP") during the calendar year
that includes the Distribution Date, effective as of Immediately after the
Distribution Date, AUSHC shall transfer to the corresponding New AI Health and
Welfare Plan the account balances of AI Employees for such calendar year under
the AUSHC HCSAP, regardless of whether the account balance is positive or
negative, unless the Distribution Date shall occur in December 2000, in which
case, AUSHC shall retain such account balances and shall permit AI Employees to
submit eligible expenses incurred during calendar year 2000 under applicable
AUSHC HCSAP rules.

         (b) To the extent any AI Employee contributed to the AUSHC Dependant
Care Spending Account Plan ("AUSHC DCSAP") during the calendar year that
includes the Distribution Date, effective as of Immediately after the
Distribution Date, AUSHC shall transfer to the corresponding New AI Health and
Welfare Plan the account balances of AI Employees for such calendar year in the
AUSHC DCSAP Plan, unless the Distribution Date shall occur in December 2000, in
which case, AUSHC shall retain such account balances and shall permit AI
employees to submit eligible expenses incurred during calendar year 2000 under
applicable AUSHC DCSAP rules.

         Section 4.08. PTO Policy. During the calendar year in which the
Distribution Date occurs, each AI Employee shall be permitted under the relevant
New AI Plan to accrue paid time off ("PTO") days calculated under the relevant
AUSHC Health and

<PAGE>

Welfare Plan's PTO POLICY immediately before the Close of the Distribution Date,
and to use such PTO days during such calendar year as if the Distribution Date
had not occurred, or to carry over to the following calendar year five such PTO
days.

         Section 4.09. APPLICATION OF ARTICLE 4 TO THE AI COMPANIES. Any
reference in this Article 4 to "AI" shall include a reference to the AI
Companies when and to the extent AI has caused an AI Company to (a) become a
party to a vendor contract, group insurance contract, or HMO letter agreement
associated with a New AI Health and Welfare Plan, (b) become a self-insured
entity for the purposes of one or more New AI Health and Welfare Plans, (c)
assume all or a portion of the liabilities or administrative responsibilities
for benefits which arose before the Distribution Date under an AUSHC Health and
